Insulin Degludec v. Insulin Glargine U100: Overall risk of symptomatic hypoglycemia was reduced in patients with types 1 and 2 diabetes in the SWITCH 1 (pp. 33–44; W. Lane, mountaindiabetes@msn.com). and SWITCH 2 (pp. 45–56; C. Wysham, chwysham@comcast.net) trials. Study implications are analyzed in two related articles.
“Any basal insulin associated with a reduced rate of hypoglycemia would seem to represent an advance in therapy,” editorialists conclude after listing caveats (
pp. 31–2): “First, these insulin types were titrated using a set protocol that probably exceeds common clinical practice, so cautious clinicians may want to see the results of a more pragmatic trial. Second, the studies were funded by the manufacturer of insulin degludec; however, the study design with randomization and blinding of drug assignment to the study participants and study team helped reduce the risk of bias. Third, these results may not be generalizable to insulin glargine U300 or other alternative basal insulins. Fourth, insurance coverage and affordability are a critical component in the choice of basal insulin.” (E. R. Seaquist, seaqu001@umn.edu)
With pharmacy prices for long-acting insulin analogues such as these now exceeding $170 per vial, the costs of treating diabetes are too much for many patients with diabetes, Viewpoint authors add (
pp. 23–4). Even among patients with insurance, increased premiums and copayments are challenging, they write, adding this guidance for lower-cost human insulin: “Patients can safely switch from insulin analogues to human insulins. Total daily insulin dose can be initially reduced by 20%, because of the different profiles of action and because some patients may have been taking less analogue insulin than had been prescribed.
“For patients already treated with multiple insulin analogue injections, the number of injections and distribution of dosage can remain the same but with a 20% reduction of dosage for safety. Early contact between the physician and the patient by phone or in person is desirable to ensure that an unexpectedly large reduction of glucose has not occurred due to improved adherence.
“In summary, many patients with type 2 diabetes can be treated with human insulin. Due to high costs of analogue insulins, use of human insulin may be the only practical option for some patients, and clinicians should be familiar with its use.” (K. J. Lipska,

Cost-effectiveness of RA Therapy: In those with active rheumatoid arthritis (RA) despite 12 weeks of methotrexate therapy, moving directly to biologic therapy without first trying triple therapy provides “minimal incremental benefit,” according to RACAT researchers (pp. 8–16). Based on 24 weeks’ or lifetime therapy and societal or Medicare perspectives, the authors found that “[incremental cost-effectiveness ratios (ICERs)] for first-line etanercept–methotrexate and triple therapy were $2.7 million per [quality-adjusted life-years (QALYs)] and $0.98 million per QALY over 24 and 48 weeks, respectively. The lifetime analysis suggested that first-line etanercept–methotrexate would result in 0.15 additional lifetime QALY, but this gain would cost an incremental $77 290, leading to an ICER of $521,520 per QALY per patient.” (N. Bansback, nick.bansback@ubc.ca)
“This [study] suggests that if biosimilars can deliver the same clinical benefits at a fraction of the cost, they may offer new opportunities to revise cost-effectiveness estimates,” editorialists write (
pp. 55–6; E. Losina, elosina@bwh.harvard.edu).

Elagolix Treatment of Endometriosis-Associated Pain: An oral, nonpeptide, gonadotropin-releasing hormone (GnRH) antagonist, elagolix improved dysmenorrhea and nonmenstrual pelvic pain during a 6-month period in women with endometriosis-associated pain, researchers report (pp. 28–40). Both of two doses of the drug yielded positive results in phase 3 trials, as shown by these results: “A total of 872 women underwent randomization in Elaris EM-I and 817 in Elaris EM-II; of these women, 653 (74.9%) and 632 (77.4%), respectively, completed the intervention. At 3 months, a significantly greater proportion of women who received each elagolix dose met the clinical response criteria for the two primary end points than did those who received placebo. In Elaris EM-I, the percentage of women who had a clinical response with respect to dysmenorrhea was 46.4% in the lower-dose elagolix group and 75.8% in the higher-dose elagolix group, as compared with 19.6% in the placebo group; in Elaris EM-II, the corresponding percentages were 43.4% and 72.4%, as compared with 22.7% (P <0.001 for all comparisons). In Elaris EM-I, the percentage of women who had a clinical response with respect to nonmenstrual pelvic pain was 50.4% in the lower-dose elagolix group and 54.5% in the higher-dose elagolix group, as compared with 36.5% in the placebo group (P <0.001 for all comparisons); in Elaris EM-II, the corresponding percentages were 49.8% and 57.8%, as compared with 36.5% (P = 0.003 and P <0.001, respectively). The responses with respect to dysmenorrhea and nonmenstrual pelvic pain were sustained at 6 months. Women who received elagolix had higher rates of hot flushes (mostly mild or moderate), higher levels of serum lipids, and greater decreases from baseline in bone mineral density than did those who received placebo; there were no adverse endometrial findings.” (H. S. Taylor, hugh.taylor@yale.edu)
“A potential new drug for patients with this debilitating disease is welcome news,” an editorialist writes (
pp. 81–3). “Although surgical treatment of endometriosis-associated pelvic pain results in symptomatic improvement in most patients, medical treatment remains the mainstay of long-term management. However, no new class of drugs has been approved for endometriosis since the Food and Drug Administration approved the GnRH agonists, which are administered parenterally, more than 25 years ago.” (M. D. Hornstein)
Global Burden of Overweight & Obesity: The recent worldwide rapid increase in body-mass index (BMI) “highlights the need for continued focus on surveillance of BMI and identification, implementation, and evaluation of evidence-based interventions to address this problem,” conclude Global Burden of Disease (GBD) investigators (pp. 13–27). Between 1990 and 2015, BMI trends were as follows: “In 2015, a total of 107.7 million children and 603.7 million adults were obese. Since 1980, the prevalence of obesity has doubled in more than 70 countries and has continuously increased in most other countries. Although the prevalence of obesity among children has been lower than that among adults, the rate of increase in childhood obesity in many countries has been greater than the rate of increase in adult obesity. High BMI accounted for 4.0 million deaths globally, nearly 40% of which occurred in persons who were not obese. More than two thirds of deaths related to high BMI were due to cardiovascular disease. The disease burden related to high BMI has increased since 1990; however, the rate of this increase has been attenuated owing to decreases in underlying rates of death from cardiovascular disease.” (C. J. L. Murray, cjlm@uw.edu)
Noting gaps in the GBD data set, editorialists conclude, “Better data systems would permit policymakers in the hardest hit areas of the world to respond more quickly and to shorten the long learning period that is typically required to overcome chronic diseases.” (
pp. 80–1; E. W. Gregg).
Medications & Sudden Death in Heart Failure: The “cumulative benefit of evidence-based medications” is the likely reason for substantially reduced risks of sudden death among ambulatory patients with heart failure with reduced ejection fractions in clinical trials, a study shows (pp. 41–51; J. J. V. McMurray, john.mcmurray@glasgow.ac.uk).

Psychosis- & Antipsychotic-Related Diabetes: In a study of the Danish population, people with schizophrenia had a 3-fold greater risk of developing diabetes, and this risk was increased — but not significantly — when the condition was treated with first- or second-generation antipsychotic agents (pp. 686–94). National psychiatric and pharmacy registries yielded these estimates of endogenous and treatment-related risks for diabetes among patients with diagnoses of schizophrenia: “Of the cohort members, 14,118 (0.52%) developed diabetes, and 8,945 (0.33%) developed schizophrenia during follow-up (49,582,279 person–years). The adjusted hazard ratio for diabetes was 3.07 (95% confidence interval [CI], 1.71–5.41) in antipsychotic-naive schizophrenia compared with the general population. The risk for diabetes after starting antipsychotic treatment was significantly higher (adjusted hazard ratio, 3.64; 95% CI, 1.95–6.82) than the risk in antipsychotic-naive schizophrenia, after adjustment for family history of diabetes and other potential confounders. First-line treatment with either first-generation antipsychotics (adjusted hazard ratio, 3.06; 95% CI, 1.32–7.05) or second-generation antipsychotics (adjusted hazard ratio, 3.44; 95% CI, 1.73–6.83) increased the risk for diabetes without a statistically significant difference. Appropriate sensitivity analyses limited to type 2 diabetes corroborated these results.” (A. P. Rajkumar, anto.rajamani@kcl.ac.uk)
“Long before antipsychotic drugs became standard therapy, studies showed abnormal glucose tolerance in patients with ‘dementia praecox’ (schizophrenia),” an editorialist writes (
pp. 616–7). “Recent studies of patients in the early phase before initiating drug therapy also show impaired glucose tolerance at the group level. Together, with the data of Rajkumar et al., these findings suggest that some of the cause of diabetes in severe mental illness is linked to the disease itself.” (O. A. Andreassen, o.a.andreassen@medisin.uio.no)

Long-Term Metformin Outcomes in Diabetes Prevention Trial: Following 3.2 years of lifestyle and metformin interventions in patients with prediabetes, men had lower rates of coronary atherosclerosis when metformin treatment continued, researchers report (pp. 52–64). Coronary artery calcium (CAC) measurements after an average of 14 years of follow-up showed the following: “There were no CAC differences between lifestyle and placebo intervention groups in either sex. CAC severity and presence were significantly lower among men in the metformin versus the placebo group (age-adjusted mean CAC severity, 39.5 versus 66.9 Agatston units, P = 0.04; CAC presence, 75% versus 84%, P = 0.02), but no metformin effect was seen in women. In multivariate analysis, the metformin effect in men was not influenced by demographic, anthropometric, or metabolic factors; by the development of diabetes mellitus; or by use/nonuse of statin therapy.” (R. B. Goldberg, dppmail@bsc.gwu.edu)

Endo International yesterday agreed to voluntarily remove Opana ER (oxymorphone) from the market. FDA had requested the withdrawal last month, citing concerns that the product’s abuse potential created risks that exceeded benefits. Endo said that it plans to work with FDA to coordinate the orderly removal of the product “in a manner that looks to minimize treatment disruption for patients and allows patients sufficient time to seek guidance from their health care professionals.” The company also recommended that patients taking Opana ER discuss treatment options with their prescribing physician at their next visit.

PF-00547659 in Ulcerative Colitis: In a phase 2 trial of 357 patients with moderate-to-severe ulcerative colitis, the investigational monoclonal antibody PT-00547659 was safe and well tolerated and significantly more effective than placebo for induction of remission, researchers report (pp. 135–44). The agent, which binds to human mucosal addressin cell adhesion molecule-1 to selectively reduce lymphocyte homing to the intestinal tract, was effective in some but not nearly all participants on active therapy: “Remission rates at week 12 were significantly greater in three of four active-treatment groups than in the placebo group (2.7% [two of 73]): 7.5 mg (11.3% [eight of 71]), 22.5 mg (16.7% [12 of 72]), 75 mg (15.5% [11 of 71]), and 225 mg (5.7% [four of 70]).… Four of 73 (5.5%) patients had a serious adverse event in the placebo group, ten of 71 (14.1%) in the 7.5 mg group, one of 70 (1.4%) in the 22.5 mg group, three of 73 (4.1%) in the 75 mg group, and three of 70 (4.3%) in the 225 mg group. No safety signal was observed for the study drug.” (S. Vermeire, severine.vermeire@uzleuven.be)
NSAIDs in Knee and Hip Osteoarthritis: For reducing pain and maintaining function in patients with knee and hip osteoarthritis, diclofenac 150 mg/d is the most effective NSAID available, according to authors of a network meta-analysis (pp. e21–e33). Concluding acetaminophen should not be used alone in managing this condition, the authors report these results from 76 trials of 58,451 patients: “For six interventions (diclofenac 150 mg/day, etoricoxib 30 mg/day, 60 mg/day, and 90 mg/day, and rofecoxib 25 mg/day and 50 mg/day), the probability that the difference to placebo is at or below a prespecified minimum clinically important effect for pain reduction (effect size [ES] −0.37) was at least 95%. Among maximally approved daily doses, diclofenac 150 mg/day (ES −0.57, 95% credibility interval [CrI] −0.69 to −0.45) and etoricoxib 60 mg/day (ES −0.58, −0.74 to −0.43) had the highest probability to be the best intervention, both with 100% probability to reach the minimum clinically important difference. Treatment effects increased as drug dose increased, but corresponding tests for a linear dose effect were significant only for naproxen (p = 0.034).” (S. Trelle, sven.trelle@ctu.unibe.ch)

Benzodiazepines & All-Cause Mortality Risk: The risk of all-cause mortality changes little following initiation of benzodiazapine therapy in adults, according to a retrospective cohort study of a large American health care database (j2941). Among 1.2 million people in a user cohort and a nonuser control group, these trends were noted in 2004–13: “Over a six month follow-up period, 5,061 and 4,691 deaths occurred among high dimensional propensity score matched benzodiazepine initiators versus non-initiators (9.3 v 9.4 events per 1,000 person–years; hazard ratio 1.00, 95% confidence interval 0.96 to 1.04). A 4% (95% confidence interval 1% to 8%) to 9% (2% to 7%) increase in mortality risk was observed associated with the start of benzodiazepine treatment for follow-ups of 12 and 48 months and in subgroups of younger patients and patients initiating short acting agents. In secondary analyses comparing 1:1 high dimensional propensity score matched patients initiating benzodiazepines with an active comparator, ie, patients starting treatment with selective serotonin reuptake inhibitor antidepressants, benzodiazepine use was associated with a 9% (95% confidence interval 3% to 16%) increased risk.” (E.

Statins in Older Adults: In a post-hoc analysis from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial–Lipid-Lowering Trial (ALLHAT-LLT), older adults did not show benefit from pravastatin therapy for primary prevention, and those aged 75 years or older had a nonsignificant increase in all-cause mortality (pp. 955–65). Among 2,867 adults 65 years or older with moderate hyperlipidemia, pravastatin 40 mg/d or usual care (UC) produced these outcomes: “The baseline mean (SD) low-density lipoprotein cholesterol levels were 147.7 (19.8) mg/dL in the pravastatin group and 147.6 (19.4) mg/dL in the UC group; by year 6, the mean (SD) low-density lipoprotein cholesterol levels were 109.1 (35.4) mg/dL in the pravastatin group and 128.8 (27.5) mg/dL in the UC group. At year 6, of the participants assigned to pravastatin, 42 of 253 (16.6%) were not taking any statin; 71.0% in the UC group were not taking any statin. The hazard ratios for all-cause mortality in the pravastatin group vs the UC group were 1.18 (95% CI, 0.97–1.42; P = .09) for all adults 65 years and older, 1.08 (95% CI, 0.85–1.37; P = .55) for adults aged 65 to 74 years, and 1.34 (95% CI, 0.98–1.84; P = .07) for adults 75 years and older. Coronary heart disease event rates were not significantly different among the groups. In multivariable regression, the results remained nonsignificant, and there was no significant interaction between treatment group and age.” (B. H. Han, benjamin.han@nyumc.org)
“Statin therapy may be associated with a variety of musculoskeletal disorders, including myopathy, myalgias, muscle weakness, back conditions, injuries, and arthropathies,” an editorialist writes (
p. 966). “These disorders may be particularly problematic in older people and may contribute to physical deconditioning and frailty. Statins have also been associated with cognitive dysfunction, which may further contribute to reduced functional status, risk of falls, and disability. The combination of these multiple risks and the ALLHAT-LLT data showing that statin therapy in older adults may be associated with an increased mortality rate should be considered before prescribing or continuing statins for patients in this age category.” (G. Curfman, gregory_curfman@hms.harvard.edu)
Glucose Self-monitoring in Non–Insulin-Treated Type 2 Diabetes: Self-monitoring of blood glucose (SMBG) by patients with non–insulin-dependent type 2 diabetes produced no clinically or statistically significant differences at 1 year, even when enhanced with automated, tailored messaging, according to a study of glycemic control and health-related quality of life (HRQOL) (pp. 920–9). The Monitor Trial study produced the following open-label, pragmatic results at 15 North Carolina primary care practices: “A total of 450 patients were randomized and 418 (92.9%) completed the final visit. There were no significant differences in hemoglobin A1c levels across all 3 groups (P = .74; estimated adjusted mean hemoglobin A1c difference, SMBG with messaging vs no SMBG, −0.09%; 95% CI, −0.31% to 0.14%; SMBG vs no SMBG, −0.05%; 95% CI, −0.27% to 0.17%). There were also no significant differences found in HRQOL. There were no notable differences in key adverse events including hypoglycemia frequency, health care utilization, or insulin initiation.” (K. Donahue, kdonahue@med.unc.edu)
Community Health Worker Intervention in Type 2 Diabetes: Just one of three outcomes was significantly improved by a community health worker intervention in Latinos with type 2 diabetes, researchers report (pp. 948–54).

Antidepressant Switching/Augmentation in Resistant Depression: Augmentation of therapy with the second-generation antipsychotic agent aripiprazole following antidepressant failure in 1,522 VA patients with nonpsychotic major depressive disorder (MDD) yielded limited benefits but increased adverse effects, researchers report (pp. 132–45). Compared with a switch to or augmentation with bupropion, augmentation with aripiprazole produced these results during an acute treatment phase of 12 weeks in the VA Augmentation and Switching Treatments for Improving Depression Outcomes (VAST-D) study: “Remission rates at 12 weeks were 22.3% (n = 114) for the switch group, 26.9% (n = 136)for the augment-bupropion group, and 28.9% (n = 146) for the augment-aripiprazole group. The augment-aripiprazole group exceeded the switch group in remission (relative risk [RR], 1.30 [95% CI, 1.05–1.60]; P = .02), but other remission comparisons were not significant. Response was greater for the augment-aripiprazole group (74.3%) than for either the switch group (62.4%; RR, 1.19 [95% CI, 1.09-–1.29]) or the augment-bupropion group (65.6%; RR, 1.13 [95% CI, 1.04–1.23]). No significant treatment differences were observed for relapse. Anxiety was more frequent in the 2 bupropion groups (24.3% in the switch group [n = 124] vs 16.6% in the augment-aripiprazole group [n = 84]; and 22.5% in augment-bupropion group [n = 114]). Adverse effects more frequent in the augment-aripiprazole group included somnolence, akathisia, and weight gain.” (S. Mohamed, somaia.mohamed@va.gov)
These findings “showed a modest yet significant advantage for the aripiprazole augmentation compared with switching to bupropion (in terms of both higher remission and response rates) and bupropion augmentation (in terms of higher response rates only) in a population of patients with MDD and inadequate response to antidepressant therapy,” writes an editorialist (
pp. 126–8). “The VAST-D study was uniquely enriched by men and by those with [posttraumatic stress disorder] comorbidity, and offers an important perspective on the role of treatment using augmentation with atypical antipsychotic agents in this population commonly seen in VA clinics.” (M. Fava, mfava@mgh.harvard.edu)
Alendronate & Hip Fracture in Older Patients Using Oral Prednisolone: An observational study of the Swedish national health database shows benefits of alendronate therapy in older patients on medium-to-high doses of prednisolone (pp. 146–55). Over a median of 1.32 years, the risk of hip fracture was as follows in patients with a mean age of 79.9 years, 70% of whom were women: “There were 27 hip fractures in the alendronate group and 73 in the no-alendronate group, corresponding to incidence rates of 9.5 (95% CI, 6.5–13.9) and 27.2 (95% CI, 21.6–34.2) fractures per 1,000 person–years, with an absolute rate difference of −17.6 (95% CI, −24.8 to −10.4). The use of alendronate was associated with a lower risk of hip fracture in a multivariable-adjusted Cox model (hazard ratio, 0.35; 95% CI, 0.22–0.54). Alendronate treatment was not associated with increased risk of mild upper gastrointestinal tract symptoms (alendronate vs no alendronate, 15.6 [95% CI, 11.6–21.0] vs 12.9 [95% CI, 9.3–18.0] per 1,000 person–years; P = .40) or peptic ulcers (10.9 [95% CI, 7.7–15.5] vs 11.4 [95% CI, 8.0–16.2] per 1,000 person–years; P = .86). There were no cases of incident drug-induced osteonecrosis and only 1 case of femoral shaft fracture in each group.” (M. Lorentzon, mattias.lorentzon@medic.gu.se)

Clonal Hematopoiesis & Atherosclerosis: Evidence of increased risk of atherosclerotic cardiovascular disease associated with a genetic peripheral blood disorder comes from studies of mice and people (pp. 111–21). Clonal hematopoiesis of indeterminate potential (CHIP) is the presence of an expanded somatic blood-cell clone in people without other hematologic abnormalities, and it has been linked to an increased risk of hematologic cancer. Seeking to explore the relationship further, investigators conducted whole-exome sequencing of samples from four case–control studies of 8,255 participants and examined function of the Tet2 gene in atherosclerosis-prone mice. Results showed the following: “In nested case–control analyses from two prospective cohorts, carriers of CHIP had a risk of coronary heart disease that was 1.9 times as great as in noncarriers (95% confidence interval [CI], 1.4 to 2.7). In two retrospective case–control cohorts for the evaluation of early-onset myocardial infarction, participants with CHIP had a risk of myocardial infarction that was 4.0 times as great as in noncarriers (95% CI, 2.4 to 6.7). Mutations in DNMT3A, TET2, ASXL1, and JAK2 were each individually associated with coronary heart disease. CHIP carriers with these mutations also had increased coronary-artery calcification, a marker of coronary atherosclerosis burden. Hypercholesterolemia-prone mice that were engrafted with bone marrow obtained from homozygous or heterozygous Tet2 knockout mice had larger atherosclerotic lesions in the aortic root and aorta than did mice that had received control bone marrow. Analyses of macrophages from Tet2 knockout mice showed elevated expression of several chemokine and cytokine genes that contribute to atherosclerosis.” (B. L. Ebert, bebert@partners.org)
Adjuvant Pertuzumab & Trastuzumab in Early HER2-Positive Breast Cancer: Added to trastuzumab and chemotherapy, pertuzumab significantly improved the rates of invasive-disease–free survival among patients with HER2-positive, operable breast cancer, the APHINITY study shows (pp. 122–31): “Disease recurrence occurred in 171 patients (7.1%) in the pertuzumab group and 210 patients (8.7%) in the placebo group (hazard ratio, 0.81; 95% confidence interval [CI], 0.66 to 1.00; P = 0.045). The estimates of the 3-year rates of invasive-disease–free survival were 94.1% in the pertuzumab group and 93.2% in the placebo group. In the cohort of patients with node-positive disease, the 3-year rate of invasive-disease–free survival was 92.0% in the pertuzumab group, as compared with 90.2% in the placebo group (hazard ratio for an invasive-disease event, 0.77; 95% CI, 0.62 to 0.96; P = 0.02). In the cohort of patients with node-negative disease, the 3-year rate of invasive-disease–free survival was 97.5% in the pertuzumab group and 98.4% in the placebo group (hazard ratio for an invasive-disease event, 1.13; 95% CI, 0.68 to 1.86; P = 0.64). Heart failure, cardiac death, and cardiac dysfunction were infrequent in both treatment groups. Diarrhea of grade 3 or higher occurred almost exclusively during chemotherapy and was more frequent with pertuzumab than with placebo (9.8% vs. 3.7%).” (G. von Minckwitz, gunter.vonminckwitz@gbg.de)

* Based on a remission rate of 82.5% in a study of 63 patients with B-cell acute lymphoblastic leukemia, an FDA advisory panel yesterday recommended that the agency approve CTL019 (Novartis), according to articles in the Wall Street Journal and New York Times. If approved as expected, the drug would be the“first-ever treatment that genetically alters a patient’s own cells to fight cancer, transforming them into what scientists call ‘a living drug’ that powerfully bolsters the immune system to shut down the disease,” the Times reports. “To use the technique, a separate treatment must be created for each patient — their cells removed at an approved medical center, frozen, shipped to a Novartis plant for thawing and processing, frozen again and shipped back to the treatment center.”
* FDA has dropped a demand that Amicus Therapeutics conduct an additional clinical study of 
migalastat in treatment of Fabry disease, according to the Wall Street Journal. The shift in this high-profile case could be first indication of “a much more pragmatic and practical approach to drug development” at FDA with Commissioner Scott Gottlieb at the helm, an analyst says.

Pharmacist-Driven ID Care: At a single hospital, an automated, pharmacist-driven intervention improved the quality of care of patients with Staphylococcus aureus bacteremia (SAB), according to an antimicrobial stewardship program (ASP) report (pp. 194–200). A patient scoring tool integrated into the electronic health record alerted pharmacists to patients with SAB. “Pharmacists utilized the scoring tool and the institution’s evidence-based practice guideline to make standardized recommendations to promote adherence to SAB quality-of-care measures and encourage [infectious diseases (ID)] consultation,” the authors report, adding these results: “In sum, 84 patients were identified for study inclusion, 45 in the pre-intervention and 39 in the intervention group. As a whole, all 4 quality-of-care components for the management of SAB were significantly more frequently adhered to in the intervention group (68.9% vs 92.3%; P = .008). The incidence of ID consult improved significantly by almost 20% in the intervention group (75.6% vs 94.9%, P = .015). No statistically significant differences in duration of bacteremia, length-of-stay, infection-related length-of-stay, or readmission were observed between the groups. The incidence of all-cause mortality was 6-fold higher in the pre-intervention group compared to the intervention group (15.6% vs 2.6%, P = .063).” (E. Wenzler)
Subacute Sclerosing Panencephalitis After Measles: A potentially fatal complication of measles, subacute sclerosing panencephalitis (SSPE) may occur more frequently than previously thought, a study shows, especially among infants (pp. 226–32). California measles cases in 1998–2015 (n = 17) had these outcomes: “Males outnumbered females 2.4:1. Twelve (71%) cases had a history of measles-like illness; all 12 had illness prior to 15 months of age. Eight (67%) children were exposed to measles in California. SSPE was diagnosed at a median age of 12 years (3–35 years), with a latency period of 9.5 years (2.5–34 years). Among measles cases reported to [the California Department of Public Health] during 1988–1991, the incidence of SSPE was 1:1367 for children <5 years, and 1:609 for children <12 months at time of measles disease.” (K.

ASCO Guideline on Potentially Curable Pancreatic Cancer: In an update to its guideline on management of potentially curable pancreatic cancer, the American Society of Clinical Oncology (ASCO) makes these recommendations (pp. 2324–8): “All patients with resected pancreatic cancer who did not receive preoperative therapy should be offered 6 months of adjuvant chemotherapy in the absence of medical or surgical contraindications. The doublet regimen of gemcitabine and capecitabine is preferred in the absence of concerns for toxicity or tolerance; alternatively, monotherapy with gemcitabine or fluorouracil plus folinic acid can be offered. Adjuvant treatment should be initiated within 8 weeks of surgical resection, assuming complete recovery. The remaining recommendations from the original 2016 ASCO guideline are unchanged.” (P. B.

“Pain Management and the Opioid Epidemic: Balancing Societal and Individual Benefits and Risks of Prescription Opioid Use” is the topic of a report issued yesterday by the National Academies of Sciences, Engineering, and Medicine (NASEM). “Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States,” NASEM writes. “The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function.” In thanking NASEM for compiling the report, FDA Commissioner Scott Gottlieb said, “We’re committed to doing our part and will continue to use our regulatory authority to reduce the scope of this immense public health crisis.”

Intraoperative Ketamine for Delirium/Pain Prophylaxis in Older Adults: In the Prevention of Delirium and Complications Associated with Surgical Treatments [PODCAST] study, adults aged 60 years or older showed few postoperative benefits from a single subanesthetic dose of ketamine during surgery (pp. 267–75). The authors note that subanesthetic ketamine is “often administered intraoperatively for postoperative analgesia, and some evidence suggests that ketamine prevents delirium.” However, among 1,360 patients undergoing major cardiac or noncardiac surgery, no decrease in delirium was noted, and the investigators conclude based on these results that the practice “might cause harm by inducing negative experiences”: “There was no difference in delirium incidence between patients in the combined ketamine groups and the placebo group (19.45% vs 19.82%, respectively; absolute difference 0.36%, 95% CI −6.07 to 7.38, p=0.92). There were more postoperative hallucinations (p = 0.01) and nightmares (p = 0.03) with increasing ketamine doses compared with placebo. Adverse events (cardiovascular, renal, infectious, gastrointestinal, and bleeding), whether viewed individually (p value for each >0.40) or collectively (36.9% in placebo, 39.6% in 0.5 mg/kg ketamine, and 40.8% in 1.0 mg/kg ketamine groups, p = 0.69), did not differ significantly across groups.” (M.

Postpregnancy Hypertension Following Hypertensive Disorders During Pregnancy: Two studies examine women’s risk of hypertension after having hypertensive disorders during pregnancy.
Analysis of the Danish nationwide registry shows that hypertension during pregnancy increased women’s risk for hypertension immediately after childbirth and continuing for 20 years (
j3078). “Up to one third of women with a hypertensive disorder of pregnancy may develop hypertension within a decade of an affected pregnancy, indicating that cardiovascular disease prevention in these women should include blood pressure monitoring initiated soon after pregnancy,” the investigators conclude. (H. A. Boyd, hoy@ssi.dk)
In the prospective cohort Nurses’ Health Study II conducted in 1991–2013, chronic hypertension after hypertensive disorders of pregnancy (HDP; gestational hypertension and pre-eclampsia) was reduced through lifestyle interventions (
j3024): “10% (n = 5,520) of women had a history of HDP at baseline. 13,971 cases of chronic hypertension occurred during 689,988 person years of follow-up. Being overweight or obese was the only lifestyle factor consistently associated with higher risk of chronic hypertension. Higher body mass index, in particular, also increased the risk of chronic hypertension associated with history of HDP (relative excess risk due to interaction P <0.01 for all age strata). For example, in women aged 40–49 years with previous HDP and obesity class I (body mass index 30.0–34.9), 25% (95% confidence interval 12% to 37%) of the risk of chronic hypertension was attributable to a potential effect of obesity that was specific to women with previous HDP. There was no clear evidence of effect modification by physical activity, DASH diet, or sodium/potassium intake on the association between HDP and chronic hypertension.” (S.

MMR Vaccines & Pretravel Health Consultations: Providers are missing opportunities to bring travelers up-to-date on measles, mumps, rubella (MMR) vaccine, according to results of surveys completed during pretravel consultations at 24 sites associated with the CDC-funded Global TravEpiNet (GTEN) (pp. 77–84). Adults born in or after 1957 and providers who saw them in 2009–14 gave these responses on structured questionnaires: “40,810 adult travelers were included; providers considered 6,612 (16%) to be eligible for MMR vaccine at the time of pretravel consultation. Of the MMR-eligible, 3,477 (53%) were not vaccinated at the visit; of these, 1,689 (48%) were not vaccinated because of traveler refusal, 966 (28%) because of provider decision, and 822 (24%) because of health systems barriers. Most MMR-eligible travelers who were not vaccinated were evaluated in the South (2,262 travelers [65%]) or at nonacademic centers (1,777 travelers [51%]). Nonvaccination due to traveler refusal was most frequent in the South (1,432 travelers [63%]) and in nonacademic centers (1,178 travelers [66%]).” (E. P. Hyle, ehyle@mgh.harvard.edu)
“All unvaccinated travelers who are medically able to receive MMR vaccine should do so,” editorialists write (
pp. 127–8). “The risks are minimal for the individual who receives the vaccine and are greatly outweighed by the benefit to the traveler, as well as to society, on his or her return. Furthermore, travel clinics present an additional contact with the health care system, through which adults and children may receive recommendations regarding all vaccinations, not only those recommended for travel. If persons traveling abroad continue to underestimate the importance of pretravel MMR vaccination, our society is destined to be affected by imported cases of measles, leading to morbidity and mortality from this disease.” (L. K. Handy, handyl@email.chop.edu)
Race & Glucose/A1C Levels: Hemoglobin A1c (HbA1c) levels overestimate mean glucose concentrations in black patients, a study shows (pp. 95–102). “However, because race only partially explains the observed HbA1c differences between black persons and white persons, future research should focus on identifying and modifying barriers impeding improved glycemic control in black persons with diabetes,” the authors add, based on these findings in this prospective, observational study of 104 black and 104 white persons aged 8 years or older with type 1 diabetes: “The mean HbA1c level was 9.1% in black persons and 8.3% in white persons. For a given HbA1c level, the mean glucose concentration was significantly lower in black persons than in white persons (P = 0.013), which was reflected in mean HbA1c values in black persons being 0.4 percentage points (95% CI, 0.2 to 0.6 percentage points) higher than those in white persons for a given mean glucose concentration. In contrast, no significant racial differences were found in the relationship of glycated albumin and fructosamine levels with the mean glucose concentration (P > 0.20 for both comparisons).” (R. L. Gal, rgal@jaeb.org)
This racial difference is not new, editorialists note (
pp. 131–2): “Data documenting this difference in the United States date back to at least the early 1980s, and much of the difference has been thought to relate to disparities in risk factors, glycemic control, access to care, and socioeconomic status.” (E. Selvin, eselvin@jhu.edu)
An Annual MIPS Fix? While the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) ended the need for the annual “doc fix” of the sustained growth rate (SGR) in Congress, a writer notes (pp. 122–4).

Vitamin D Doses & Wintertime Pediatric Viral Infections: In young healthy children, aggressive dosing of vitamin D supplements during winter months failed to reduce upper respiratory tract infections, researchers report (pp. 245–54). In Toronto, participants aged 1–5 years received vitamin D oral supplementation in doses of 400 IU/d or 2000 IU/d for 4 months or more between Sept. and May, with these results: “Among 703 participants who were randomized (mean age, 2.7 years, 57.7% boys), 699 (99.4%) completed the trial. The mean number of laboratory-confirmed upper respiratory tract infections per child was 1.05 (95% CI, 0.91–1.19) for the high-dose group and 1.03 (95% CI, 0.90–1.16) for the standard-dose group, for a between-group difference of 0.02 (95% CI, −0.17 to 0.21) per child. There was no statistically significant difference in number of laboratory-confirmed infections between groups (incidence rate ratio [RR], 0.97; 95% CI, 0.80–1.16). There was also no significant difference in the median time to the first laboratory-confirmed infection: 3.95 months (95% CI, 3.02–5.95 months) for the high-dose group vs 3.29 months (95% CI, 2.66–4.14 months) for the standard-dose group, or number of parent-reported upper respiratory tract illnesses between groups (625 for high-dose vs 600 for standard-dose groups, incidence RR, 1.01; 95% CI, 0.88–1.16). At study termination, serum 25-hydroxyvitamin D levels were 48.7 ng/mL (95% CI, 46.9–50.5 ng/mL) in the high-dose group and 36.8 ng/mL (95% CI, 35.4–38.2 ng/mL) in the standard-dose group.” (J. L. Maguire, jonathon.maguire@utoronto.ca)
Early-Life Weight Gain & Healthy Aging: Health professionals who gained weight between early and middle adulthood had poorer health outcomes in later life, including increased incidence of type 2 diabetes and obesity-related cancer in men and women, and cardiovascular disease and mortality in women, according to a cohort analysis of the Nurses’ Health Study and the Health Professionals Follow-Up Study (pp. 255–69). Participants were asked to recall their weights at 18 (women) or 21 (men) years of age. These relationships between weight gain at age 55 and later healthy aging outcomes were identified: “Among those who gained a moderate amount of weight [≥2.5–<10.0 kg], 3,651 women (24%) and 2,405 men (37%) achieved the composite healthy aging outcome [being free of 11 chronic diseases and major cognitive or physical impairment]. Among those who maintained a stable weight, 1,528 women (27%) and 989 men (39%) achieved the composite healthy aging outcome. The multivariable-adjusted odds ratio for the composite healthy aging outcome associated with moderate weight gain was 0.78 (95% CI, 0.72 to 0.84) in women and 0.88 (95% CI, 0.79 to 0.97) in men. Higher amounts of weight gain were associated with greater risks of major chronic diseases and lower likelihood of healthy aging.” (F. B. Hu, nhbfh@channing.harvard.edu)
“The prevalence of obesity emphasizes that it will not be possible to provide effective treatment for all of those affected,” an editorialist writes in response to these data (
pp. 241–2). “Therefore, efforts to prevent and control this widespread disease must be renewed. Reducing and preventing obesity and excessive weight gain in young adults provide a new target, and one that could offer an effective transgenerational approach for prevention.” (W. H.

ANGPTL3 & Cardiovascular Disease: Responding to two studies of the action of the human monoclonal antibody, evinacumab, against Angptl3 in dyslipidemic mice and against ANGPTL3 in healthy human volunteers with high triglyceride or LDL cholesterol levels (pp. 211–21, F. E. Dewey, frederick.dewey@regeneron.compp. 222–32, S. Tsimikas, stsimikas@ucsd.edu), editorialists write (pp. 280–3): “It is likely that lowering the levels of triglyceride-rich lipoproteins with agents that increase lipoprotein lipase activity will lead to a different spectrum of benefits and side effects than treatments that increase the activity of the LDL receptor. For example, increasing lipoprotein lipase activity might ameliorate insulin resistance and reduce the risk of diabetes. Insulin sensitization was shown in patients with ANGPTL3 mutations as well as in Angptl3-deficient mice, in which increased uptake of fatty acids into oxidative tissues such as muscle and brown adipose tissue led to decreased uptake of fatty acids and increased uptake of glucose in white adipose tissue. In humans, variants in lipoprotein lipase that increase its activity are associated with a reduced risk of coronary artery disease and a reduced risk of diabetes; the mechanisms linking lipoprotein lipase activity to decreased insulin resistance and diabetes may include storage of triglyceride in gluteofemoral rather than visceral fat. In contrast, genetic variants that compromise the function of 3-hydroxy-3-methylglutaryl–coenzyme A reductase (the target of statins) or PCSK9 are associated with increased diabetes risk.” (A. R. Tall)
Managing Advanced HIV Infection: In an open-label study of patients in sub-Saharan Africa of patients with advanced HIV infection, enhanced antimicrobial prophylaxis plus antiretroviral therapy (ART) reduced mortality at 24 and 48 weeks without worsening viral suppression or toxic effects, researchers report (pp. 233–45). HIV-infected adults and children aged 5 years or older with advanced immunosuppression received continuous trimethoprim–sulfamethoxazole plus at least 12 weeks of isoniazid–pyridoxine, 12 weeks of fluconazole, 5 days of azithromycin, and a single dose of albendazole, or standard prophylaxis (trimethoprim–sulfamethoxazole alone), with these results: “A total of 1,805 patients (1,733 adults and 72 children or adolescents) underwent randomization to receive either enhanced prophylaxis (906 patients) or standard prophylaxis (899 patients) and were followed for 48 weeks (loss to follow-up, 3.1%). The median baseline CD4+ count was 37 cells per cubic millimeter, but 854 patients (47.3%) were asymptomatic or mildly symptomatic. In the Kaplan–Meier analysis at 24 weeks, the rate of death with enhanced prophylaxis was lower than that with standard prophylaxis (80 patients [8.9% vs. 108 [12.2%]; hazard ratio, 0.73; 95% confidence interval [CI], 0.55 to 0.98; P = 0.03); 98 patients (11.0%) and 127 (14.4%), respectively, had died by 48 weeks (hazard ratio, 0.76; 95% CI, 0.58 to 0.99; P = 0.04). Patients in the enhanced-prophylaxis group had significantly lower rates of tuberculosis (P = 0.02), cryptococcal infection (P = 0.01), oral or esophageal candidiasis (P = 0.02), death of unknown cause (P = 0.03), and new hospitalization (P = 0.03). However, there was no significant between-group difference in the rate of severe bacterial infection (P = 0.32). There were nonsignificantly lower rates of serious adverse events and grade 4 adverse events in the enhanced-prophylaxis group (P = 0.08 and P = 0.09, respectively). Rates of HIV viral suppression and adherence to ART were similar in the two groups.” (A. Walker, rmjlasw@ucl.ac.uk)
“With the advent of new treatment options, HIV infection has evolved from a probable death sentence to a chronic disease,” editorialists write (
pp. 283–4). “If patients start ART early, they can expect a near-normal life expectancy. Early treatment also reduces the risk of HIV transmission, and much of the focus today is on reducing the spread of new infections to achieve epidemic control. Nevertheless, the relatively consistent proportion of patients who newly present for care with a low CD4+ count, together with an additional number of seriously ill patients who return for care after a period of treatment interruption, calls for a renewed focus to respond to the needs of patients with advanced HIV infection who are at high risk for illness and death.” (N. Ford)

Treat-to-Target Education in Rheumatoid Arthritis: Improved adherence resulted when patients with rheumatoid arthritis participated in a 9-month, group-based learning collaborative that focused on the treat-to-target (TTT) paradigm, researchers report (pp. 1374–80). At 5 U.S. sites, these results were recorded for 621 patients cluster-randomized to the intervention or a control group: “At baseline, the mean TTT implementation score was 11% in both arms; after the 9-month intervention, the mean TTT implementation score was 57% in the intervention group and 25% in the control group (change in score of 46% for intervention and 14% for control; P = 0.004).

Rituximab in Primary Sjögren’s Syndrome: The anti-B cell agent rituximab failed produce significant, cost-effective improvement in fatigue and oral dryness symptoms in patients with primary Sjögren’s syndrome (SS) (pp. 1440–50). At 25 U.K. rheumatology clinics, anti-Ro-positive patients were randomized to I.V. saline or rituximab 1,000 mg in saline in 2 courses over 26 weeks. Results showed: “All 133 patients who were randomized to receive placebo (n = 66) or rituximab (n = 67) were included in the primary analysis. Among patients with complete data, 21 of 56 placebo-treated patients and 24 of 61 rituximab-treated patients achieved the primary end point. After multiple imputation of missing outcomes, response rates in the placebo and rituximab groups were 36.8% and 39.8%, respectively (adjusted odds ratio 1.13 [95% confidence interval 0.50, 2.55]). There were no significant improvements in any outcome measure except for unstimulated salivary flow. The mean ± SD costs per patient for rituximab and placebo were £10,752 ± 264.75 and £2,672 ± 241.71, respectively. There were slightly more adverse events (AEs) reported in total for rituximab, but there was no difference in serious AEs (10 in each group).” (S. J. Bowman, Simon.Bowman@uhb.nhs.uk)
“Based on [these] results of the TRACTISS trial, one might be reluctant to use rituximab to treat patients with primary SS,” editorialists write (
pp. 1346–9). “However, some studies show that rituximab has a beneficial effect in a subgroup of patients, i.e., nonresponders to rituximab treatment can be characterized, and rituximab has objective biologic effects. In other words, rituximab is not the wrong drug in primary SS, but it has to be applied in a particular subgroup of patients with the disease. The same will probably hold true for other biologic agents that are tested in primary SS. The better we can identify the specific characteristics of a patient with primary SS, the better we can prescribe a particular targeted biologic agent. Precision medicine is about to become a reality in primary SS!” (H. Bootsma, h.bootsma@umcg.nl)

Allergen Immunotherapy in House Dust Mite Allergy: An expert panel provides recommendations on treatment of asthma and allergic rhinitis (AR) and use of allergen immunotherapy (AIT) in patients with house dust mite (HDM) allergy (pp. 41–52): “Most guidelines and key position papers did not provide specific recommendations on treatment of allergic asthma (AA) caused by HDM allergy, although some included AIT as a treatment option for AA in general. Around half of the guidelines stated that AIT with HDM extract was an effective treatment for AR, with several indicating sublingual immunotherapy as an option. This heterogeneity is caused by quality issues affecting studies of AIT with perennial allergens in patients with AA and AR, including use of different diagnosis and severity criteria, lack of consistent scoring or grading systems for primary and safety outcomes, and lack of consensus on treatment parameters. There is a need for well-designed clinical trials to serve as a basis for guideline recommendations. Although results from recent studies strengthen the evidence base for the efficacy and safety of sublingual immunotherapy in patients with HDM-induced AA and AR, their effect on subsequent guideline updates will depend on the methodology and evidence model used by each guideline.” (P.

Perinatal Antidepressants & Autism: Confounding may not fully explain the association between maternal use of antidepressants and development of autism, researchers report, especially in affected individuals without intellectual disabilities (j2811). In Stockholm County, Sweden, outcomes of 254,610 children born in 2001–11, including 5,378 with autism, were analyzed. Concluding that “study of the potential underlying biological mechanisms could help the understanding of modifiable mechanisms in the aetiology of autism,” the authors report these findings: “Of the 3,342 children exposed to antidepressants during pregnancy, 4.1% (n = 136) had a diagnosis of autism compared with a 2.9% prevalence (n = 353) in 12,325 children not exposed to antidepressants whose mothers had a history of a psychiatric disorder (adjusted odds ratio 1.45, 95% confidence interval 1.13 to 1.85). Propensity score analysis led to similar results. The results of a sibling control analysis were in the same direction, although with wider confidence intervals. In a negative control comparison, there was no evidence of any increased risk of autism in children whose fathers were prescribed antidepressants during the mothers’ pregnancy (1.13, 0.68 to 1.88). In all analyses, the risk increase concerned only autism without intellectual disability.” (D. Rai, Dheeraj.rai@bristol.ac.uk)
Lifestyle Interventions in Pregnancy: Using individual participant data (IPD) from studies identified through systematic review, investigators show that “diet and physical activity based interventions during pregnancy reduce gestational weight gain and lower the odds of caesarean section” (j3119): “IPD were obtained from 36 randomised trials (12,526 women). Less weight gain occurred in the intervention group than control group (mean difference −0.70 kg, 95% confidence interval −0.92 to −0.48 kg, I2 = 14.1%; 33 studies, 9,320 women). Although summary effect estimates favoured the intervention, the reductions in maternal (odds ratio 0.90, 95% confidence interval 0.79 to 1.03, I2 = 26.7%; 24 studies, 8,852 women) and offspring (0.94, 0.83 to 1.08, I2 = 0%; 18 studies, 7,981 women) composite outcomes were not statistically significant. No evidence was found of differential intervention effects across subgroups, for either gestational weight gain or composite outcomes. There was strong evidence that interventions reduced the odds of caesarean section (0.91, 0.83 to 0.99, I2 = 0%; 32 studies, 11,410 women), but not for other individual complications in IPD meta-analysis. When IPD were supplemented with study level data from studies that did not provide IPD, the overall effect was similar, with stronger evidence of benefit for gestational diabetes (0.76, 0.65 to 0.89, I2 = 36.8%; 59 studies, 16,885 women).” (K.

Continuing Statin Prescriptions After Adverse Reactions: Mortality and cardiovascular events occur less frequently when patients continue rather than stop statin therapy after adverse reactions, researchers report (10.7326/M16-0838). Structured electronic medical record data from primary care practices affiliated with two academic medical centers provide these estimates of risk of a primary composite outcome of time to a cardiovascular event (myocardial infarction or stroke) or death when statins were continued at any time during the 12 months after an adverse reaction: “Among 28,266 study patients, 19,989 (70.7%) continued receiving statin prescriptions after the adverse reaction. Four years after the presumed adverse event, the cumulative incidence of the composite primary outcome was 12.2% for patients with continued statin prescriptions, compared with 13.9% for those without them (difference, 1.7% [95% CI, 0.8% to 2.7%]; P < 0.001). In a secondary analysis of 7,604 patients for whom a different statin was prescribed after the adverse reaction, 2,014 (26.5%) had a documented adverse reaction to the second statin, but 1,696 (84.2%) of those patients continued receiving statin prescriptions.” (A. Turchin, aturchin@bwh.harvard.edu)
Internet propaganda promoting bizarre and unscientific criticisms of statins has given these life-saving drugs a bad reputation, according to a Commentary author (
10.7326/M17-1566): “What can thoughtful physicians do to counter these dangerous cults? We must work together to educate the public and enlist media support, and we must take the time to explain to our patients that discontinuing statin treatment may be a life-threatening mistake. Passive acceptance of harmful pseudoscience is not an option.” (S. E. Nissen, nissens@ccf.org)

Anticoagulant-Related Major Bleeding: In a cohort comparison of consecutive patients older than 65 years of age at five Ontario hospitals who were taking warfarin or direct oral anticoagulants (DOACs), lower in-hospital mortality rates “support the safety of DOACs in routine care and present useful baseline measures for evaluations of DOAC-specific reversal agents” (pp. 81–91): “Among 19,061 records screened, 2,002 (460 receiving DOAC, 1,542 receiving warfarin) were eligible. Reversal agents (72.9% vitamin K, 40.7% prothrombin complex concentrates) were frequently used in warfarin bleeding events. Red blood cell transfusions occurred more often in DOAC bleeding events than in warfarin events (52.0% vs 39.5%; adjusted relative risk [aRR], 1.32; 95% CI, 1.19–2.47). However, units of blood products transfused were not different between the two groups. Thirty-four DOAC cases (7.4%) received activated prothrombin complex concentrates or recombinant factor VIIa. In-hospital mortality was lower following DOAC bleeding events (9.8% vs 15.2%; aRR, 0.66; 95% CI, 0.49–0.89), although differences in 30-day mortality did not reach statistical significance (12.6% vs 16.3%; aRR, 0.79; 95% CI, 0.61–1.03).” (A. P. Johnson, ana.johnson@queensu.ca)
IV Magnesium Sulfate for Bronchiolitis: Among 162 infants and young children with bronchiolitis, IV magnesium did not provide benefit and might have been harmful, a study shows (pp. 113–9). Outcomes following a single 100 mg/kg dose of the drug were as follows: “Geometric mean time until medical readiness for discharge was 24.1 h (95% CI, 20.0–29.1) for the 78 magnesium-treated patients and 25.3 h (95% CI, 20.3–31.5) for the 82 patients receiving placebo (ratio, 0.95 [95% CI, 0.52–1.80]; P = .91). Mean bronchiolitis severity scores over time were similar for the two groups. The frequency of clinic visits in the subsequent 2 weeks (33.8% and 27.2%, respectively) was also similar. Fifteen magnesium recipients (19.5%) vs five placebo recipients (6.2%) were readmitted to the infirmary or hospital within 2 weeks (P = .016). No acute cardiorespiratory side effects were reported.” (K. Alansari, dkmaa@hotmail.com)

PPI Usage & Risk of Pneumonia in Dementia: In a retrospective cohort study based on the Taiwanese National Health Insurance Research Database, patients with dementia had an 89% increased risk of pneumonia when taking PPIs (pp. 1441–7). Pneumonia occurred with these frequencies in 786 patients on PPIs and 786 matched controls, all of whom had dementia: “Incidence of pneumonia was higher among patients with PPI usage (adjusted hazard ratio (HR) = 1.89; 95% CI = 1.51–2.37). Cox model analysis also demonstrated that age (adjusted HR = 1.05; 95% CI = 1.03–1.06), male gender (adjusted HR = 1.57; 95% CI = 1.25–1.98), underlying cerebrovascular disease (adjusted HR = 1.30; 95% CI = 1.04–1.62), chronic pulmonary disease (adjusted HR = 1.39; 95% CI = 1.09–1.76), congestive heart failure (adjusted HR = 1.54; 95% CI = 1.11–2.13), diabetes mellitus (adjusted HR = 1.54; 95% CI = 1.22–1.95), and usage of antipsychotics (adjusted HR = 1.29; 95% CI = 1.03–1.61) were independent risk factors for pneumonia. However, usage of cholinesterase inhibitors and histamine receptor-2 antagonists were shown to decrease pneumonia risk.” (C-B Yeh, sky5ff@gmail.com)
Managing Medications & Finances in Older Adults: Sizable proportions of adults aged 65 years or older need help managing medications and finances as they age, according to a prospective cohort study of 9,434 participants in the Health and Retirement Study (HRS), researchers report (pp. 1455–61): “The 10 years incidence of difficulty increased markedly with age, ranging from 10.3% (95% CI 9.3–11.6) for managing medications and 23.1% (95% CI 21.6–24.7) for managing finances in those aged 65–69, to 38.2% (95% CI 33.4–43.5) for medicines and 69% (95% CI 63.7–74.3) for finances in those over age 85. Women had a higher probability of developing difficulty managing medications and managing finances than men.” (N. Bleijenberg, n.bleijenberg@umcutrecht.nl)

Reducing Antipsychotics for Dementia in Nursing Homes: Analysis of 86,163 state recertification surveys of U.S. nursing homes shows the impact of three CMS strategies initiated in 2012 and 2013 for reducing antipsychotic use for managing behavioral symptoms of dementia (pp. 1299–308): “We found that these strategies were associated with increases in citations for only one of two targeted deficiencies (unnecessary drug use) and only after the third strategy (revisions to the federal guidelines for the citations) was implemented. Each strategy was associated with a modest but significant reduction in antipsychotic prevalence in the general nursing home population. Initial reductions were greater in the ten states with the highest prevalence of antipsychotic use in nursing homes, compared to the ten states with the lowest prevalence. Use of other psychoactive medications, some of which are potential substitutes for antipsychotics, varied with each strategy and by state. Continuous monitoring and consistent enforcement are needed to ensure the continued decline in unnecessary use of antipsychotics and psychoactive medications in nursing homes.” (J. A.

Continuity of Care & Drug Interactions: Among 1 million Taiwanese beneficiaries, improved continuity of care (COC) was associated with reduced drug–drug interactions (DDIs) (pp. 744–51). In 2005 through 2013, national health insurance claims yielded these rnegative nominal regression results: “Higher COC was found to decrease the risk of DDI, and this risk reduction was even greater with physician COC and a higher Charlson comorbidity index. In the 1-year observation interval, patients exhibited a 3% reduction in DDIs for every 0.1 increment in their COC index. The ability of COC to reduce DDIs increased with the level of comorbidity. Similar results were observed when the observation interval was increased.” (J-Y Guo)

Tocilizumab in Giant-Cell Arteritis: Phase 3 results for tocilizumab, recently approved by FDA for treatment of patients with giant-cell arteritis, are presented (pp. 317–28). In the Giant-Cell Arteritis Actemra (GiACTA) trial, the agent was combined with a 26-week prednisone taper and compared with either 26- or 52-week prednisone tapering, with these results: “Sustained remission at week 52 occurred in 56% of the patients treated with tocilizumab weekly and in 53% of those treated with tocilizumab every other week, as compared with 14% of those in the placebo group that underwent the 26-week prednisone taper and 18% of those in the placebo group that underwent the 52-week prednisone taper (P <0.001 for the comparisons of either active treatment with placebo). The cumulative median prednisone dose over the 52-week period was 1,862 mg in each tocilizumab group, as compared with 3,296 mg in the placebo group that underwent the 26-week taper (P <0.001 for both comparisons) and 3,818 mg in the placebo group that underwent the 52-week taper (P <0.001 for both comparisons). Serious adverse events occurred in 15% of the patients in the group that received tocilizumab weekly, 14% of those in the group that received tocilizumab every other week, 22% of those in the placebo group that underwent the 26-week taper, and 25% of those in the placebo group that underwent the 52-week taper. Anterior ischemic optic neuropathy developed in one patient in the group that received tocilizumab every other week.” (J. H. Stone, jhstone@mgh.harvard.edu)
“Additional studies are needed before tocilizumab can be recommended for all patients with active giant-cell arteritis,” an editorialist writes (
pp. 385–6). “As Stone et al. emphasize, the long-term effect of tocilizumab cannot be determined in 1 year. Although tocilizumab was much more effective than prednisone alone, only approximately 50% of the patients treated with tocilizumab had prednisone-free remission. Perhaps blocking other cytokines or cells (such as T cells) or interrupting multiple pathways will be more effective. The previous report of a patient with giant-cell arteritis who appeared to have remission with tocilizumab but had a myocardial infarction and was found to have active arteritis suggests that tocilizumab may suppress manifestations of giant-cell arteritis (especially the elevated CRP level) without eliminating the arteritis.” (D. B. Hellmann)
Abiraterone for Prostate Cancer: Two clinical trials demonstrate benefits of abiraterone in men with prostate cancer sensitive to adrogen-deprivation therapy (ADT) or castration. In the Systemic Therapy in Advancing or Metastatic Prostate Cancer: Evaluation of Drug Efficacy (STAMPEDE) trial, ADT plus abiraterone and prednisolone was associated with significantly higher rates of overall and failure-free survival than ADT alone, investigators conclude (pp. 338–51). “There were 184 deaths in the combination group as compared with 262 in the ADT-alone group (hazard ratio, 0.63; 95% confidence interval [CI], 0.52 to 0.76; P <0.001); the hazard ratio was 0.75 in patients with nonmetastatic disease and 0.61 in those with metastatic disease,” the authors report. “There were 248 treatment-failure events in the combination group as compared with 535 in the ADT-alone group (hazard ratio, 0.29; 95% CI, 0.25 to 0.34; P <0.001); the hazard ratio was 0.21 in patients with nonmetastatic disease and 0.31 in those with metastatic disease.” (N.D. James, mrcctu.stampede_publications@ucl.ac.uk)
“The addition of abiraterone acetate and prednisone to androgen-deprivation therapy significantly increased overall survival and radiographic progression-free survival in men with newly diagnosed, metastatic, castration-sensitive prostate cancer,” according to Systemic Therapy in Advancing or Metastatic Prostate Cancer: Evaluation of Drug Efficacy (STAMPEDE) investigators (
pp. 352–60; K. Fizazi, karim.fizazi@gustaveroussy.fr).
“The results of these two trials establish new and positive directions for oncologists who treat patients with prostate cancer and provide mechanistic challenges for investigators who study metastatic prostate cancer,” concludes an editorialist (
pp. 388–90). “A focus on metastatic, castration-sensitive prostate cancer may achieve major improvements in survival in a patient population that will tolerate multiple agents.” (C. J. Logothetis)

Metformin v. GLP-1 Receptor Agonists for First-Line Type 2 Diabetes Therapy: In a point–counterpoint exchange, authors debate the role of metformin versus liraglutide or another GLP-1 receptor agonist (GLP-1 RA) as foundational therapy in patients with type 2 diabetes (T2D). Introducing the pair of articles, the ADA Chief Scientific, Medical & Mission Officer first points to metformin’s 30-year track record of affordability and tolerability. “However, based on the release of newer agents over the recent past, some have suggested that the modern approach to disease management should be based upon identification of its etiology and correcting the underlying biological disturbances,” W. T. Cefalu writes. “That is, we should use interventions that normalize or at least ameliorate the recognized derangements in physiology that drive the clinical manifestation of disease, in this circumstance, hyperglycemia. Thus, it is argued that therapeutic interventions that target glycemia but do not correct the underlying pathogenic disturbances are unlikely to result in a sustained benefit on the disease process.”
“The currently available clinical and scientific evidence is overwhelmingly in favor of the use of GLP-1 RAs over metformin as first-line therapy in newly diagnosed T2D patients,” proponents conclude (
pp. 1121–7). “GLP-1 RAs … (1) correct six of the eight components of the Ominous Octet, (2) prevent/reverse the progressive beta-cell failure and rise in HbA1c, and (3) lower cardiovascular risk in T2D independent of their glucose-lowering ability.” (M. Abdul-Ghani, abdulghani@uthscsa.edu)
“In order to replace metformin as the preferred initial drug in type 2 diabetes, a head-to-head trial with the proposed agent would need to be conducted, assessing the relative effects on glycemia and both macrovascular and microvascular outcomes,” the counterpoint author writes (
pp. 1128–32). He concludes, “Based on the medical community’s extensive experience and the drug’s demonstrated efficacy, safety, low cost, and cardiovascular benefits, metformin should remain the ‘foundation therapy’ for all patients with type 2 diabetes, barring contraindications. There is no convincing evidence at the present time to consider any other approach.” (S. E. Inzucchi, silvio.inzucchi@yale.edu)
A1C — The Fallacy of Average: “Estimating glycemic control from HbA1c alone is in essence applying a population average to an individual, which can be misleading,” authors write (pp. 994–9). “Thus, a patient’s [continuous glucose monitoring] profile has considerable value for optimizing his or her diabetes management. In this era of personalized, precision medicine, there are few better examples with respect to the fallacy of applying a population average to a specific patient rather than using specific information about the patient to determine the optimal approach to treatment.” (R. W. Beck, rbeck@jaeb.org)
Severe Hypoglycemia in Type 1 Diabetes: “Severe hypoglycemia persists and remains a challenge for patients with type 1 diabetes across their life span,” authors conclude based on 30 years of follow-up in the Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Inverventions and Complications (EDIC) cohort (pp. 1010–6): “One-half of the DCCT/EDIC cohort reported episodes of severe hypoglycemia. During EDIC, rates of severe hypoglycemia fell in the former DCCT intensive treatment group but rose in the former conventional treatment group, resulting in similar rates (36.6 vs. 40.8 episodes per 100 patient–years, respectively) with a relative risk of 1.12 (95% CI 0.91–1.37). A preceding episode of severe hypoglycemia was the most powerful predictor of subsequent episodes. Entry into the DCCT study as an adolescent was associated with an increased risk of severe hypoglycemia, whereas insulin pump use was associated with a lower risk. Severe hypoglycemia rates increased with lower HbA1c similarly among participants in both treatment groups.” (R. A. Gubitosi-Klug, rose.gubitosi-klug@case.edu)

Gastroprotection Needed In Older Adults on Aspirin: The risk of major bleeding is excessively high in the 75-or-older age group when taking aspirin for antiplatelet therapy without PPI protection, a study shows (pp. 490–9). “Given that half of the major bleeds in patients aged 75 years or older were upper gastrointestinal, the estimated [number needed to treat (NNT)] for routine PPI use to prevent such bleeds is low, and co-prescription should be encouraged,” Oxford Vascular Study investigators conclude. “The estimated NNT for routine PPI use to prevent one disabling or fatal upper gastrointestinal bleed over 5 years fell from 338 for individuals younger than 65 years, to 25 for individuals aged 85 years or older.” (P.

Smoking Cessation & E-cigarette Use: As Americans have increased use of electronic cigarettes, smoking cessation rates have increased, according to data from the U.S. Current Population Survey–Tobacco Use Supplement (CPS-TUS) for time periods between 2001 and 2014 (j3262). “These findings need to be weighed carefully in regulatory policy making regarding e-cigarettes and in planning tobacco control interventions,” the authors conclude based on these findings: “Of 161,054 respondents to the 2014–15 survey, 22,548 were current smokers and 2,136 recent quitters. Among them, 38.2% of current smokers and 49.3% of recent quitters had tried e-cigarettes, and 11.5% and 19.0% used them currently (every day or some days). E-cigarette users were more likely than non-users to attempt to quit smoking, 65.1% v 40.1% (change = 25.0%, 95% confidence interval 23.2% to 26.9%), and more likely to succeed in quitting, 8.2% v 4.8% (3.5%, 2.5% to 4.5%). The overall population cessation rate for 2014–15 was significantly higher than that for 2010–11, 5.6% v 4.5% (1.1%, 0.6% to 1.5%), and higher than those for all other survey years (range 4.3–4.5%).” (S-H Zhu, szhu@ucsd.edu)
“The study findings are not entirely novel: recent research using a different methodology published in this journal from the United Kingdom drew similar conclusions,” writes an editorialist (
j3506). “Notably, both studies analysed data from populations in countries with (currently) relatively liberal regulatory approaches towards e-cigarettes. The research by Zhu and colleagues suggests that where such permissive approaches to e-cigarettes exist—ones that enable smokers to have ready access to products that deliver nicotine effectively, at a price lower than that of tobacco cigarettes—then substantial numbers of smokers will make the transition away from smoking, and a substantial population benefit can result. In light of this evidence, policy makers in countries contemplating a more restrictive approach to the regulation of e-cigarettes should pause to consider if pursuing such a course of action is the right thing to do for population health.” (C.

Outcomes in Dose Reduction or Termination of Long-Term Opioid Therapy: Options for reducing or discontinuing long-term opioid therapy (LTOT) are numerous and possibly effective, authors of a systematic review report, but interventions are supported by very low quality evidence (pp. 181–91): “Sixty-seven studies (11 randomized trials and 56 observational studies) examining 8 intervention categories, including interdisciplinary pain programs, buprenorphine-assisted dose reduction, and behavioral interventions, were found. Study quality was good for 3 studies, fair for 13 studies, and poor for 51 studies. Many studies reported dose reduction, but rates of opioid discontinuation ranged widely across interventions and the overall quality of evidence was very low. Among 40 studies examining patient outcomes after dose reduction (very low overall quality of evidence), improvement was reported in pain severity (8 of 8 fair-quality studies), function (5 of 5 fair-quality studies), and quality of life (3 of 3 fair-quality studies).” (J. W. Frank, joseph.frank@ucdenver.edu)
“Although it will be important to confirm the results with more and higher-quality studies, Frank and colleagues’ review provides evidence that patients who work with clinicians to reduce or discontinue opioid use can expect improvements in pain, function, and quality of life,” editorialists write (
pp. 208–9). “Clinicians should find comfort in being able to communicate this hope to patients. As the authors note, ‘In the realm of opioid therapy, patient safety and pain relief have often been framed as conflicting and mutually exclusive goals…[new evidence] holds the potential to fundamentally alter the conversation about opioid tapering.’ It will be heartening for many clinicians and patients to realize that indefinite continuation of opioid therapy is not always a foregone conclusion. It is possible to reduce opioid use and associated risks while reducing pain and improving function and quality of life.” (D. Dowell, ddowell@cdc.gov)
Generic Drug Prices & Market Competition: The less competition among generic drug products, the higher the prices, according to a retrospective cohort study (pp. 145–51). Over 5.5 years, 11 study periods of 6 months each provided the following insights into the Herfindahl–Hirschman Index (HHI; sum of the squares of individual manufacturers’ market shares, with higher values indicating a less competitive market): “From 1.08 billion prescription claims, a cohort of 1,120 generic drugs was identified. After adjustment, drugs with quadropoly (HHI value of 2,500, indicating relatively high levels of competition), duopoly (HHI value of 5,000), near-monopoly (HHI value of 8,000), and monopoly (HHI value of 10,000) levels of baseline competition were associated with price changes of −31.7% (95% CI, −34.4% to −28.9%), −11.8% (CI, −18.6% to −4.4%), 20.1% (CI, 5.5% to 36.6%), and 47.4% (CI, 25.4% to 73.2%), respectively, over the study period.” (C.

Antithrombotic Therapy in Essential Thrombocythemia: At high risk for both thrombosis and hemorrhage, patients with essential thrombocythemia (ET) are often treated with antithrombotic therapy, but evidence supporting this intervention is lacking, researchers report (pp. 170–80). No relevant randomized trials were identified in a systematic review; results of 24 observational studies showed the following: “Findings were inconsistent and imprecise. The reported incidence rates of thrombosis, any bleeding, and major bleeding without antiplatelet therapy ranged from 5 to 110 (median, 20), from 3 to 39 (median, 8), and from 2 to 53 (median, 6) cases per 1,000 patient–years, respectively. The reported relative risks for thrombosis, any bleeding, and major bleeding with antiplatelet therapy compared with none ranged from 0.26 to 3.48 (median, 0.74), from 0.48 to 11.04 (median, 1.95), and from 0.48 to 5.17 (median, 1.30), respectively.” (D.

Oral Methylprednisolone in IgA Nephropathy: In the Therapeutic Evaluation of Steroids in IgA Nephropathy Global (TESTING) study, oral corticosteroid therapy increased the risk of adverse events in patients with IgA nephropathy and persistent proteinuria, researchers report (pp. 432–42). Oral methylprednisolone or placebo were administered for 2 months and tapered for 4–6 months, with these results before early study termination: “After randomization of 262 participants (mean age, 38.6 [SD, 11.1] years; 96 [37%] women; eGFR, 59.4 mL/min/1.73 m2; urine protein excretion, 2.40 g/d) and 2.1 years’ median follow-up, recruitment was discontinued because of excess serious adverse events. Serious events occurred in 20 participants (14.7%) in the methylprednisolone group vs 4 (3.2%) in the placebo group (P = .001; risk difference, 11.5% [95% CI, 4.8%–18.2%]), mostly due to excess serious infections (11 [8.1%] vs 0; risk difference, 8.1% [95% CI, 3.5%–13.9%]; P <.001), including 2 deaths. The primary renal outcome occurred in 8 participants (5.9%) in the methylprednisolone group vs 20 (15.9%) in the placebo group (hazard ratio, 0.37 [95% CI, 0.17–0.85]; risk difference, 10.0% [95% CI, 2.5%–17.9%]; P = .02).” (H. Zhang, hongzh@bjmu.edu.cn)
“Whether concomitant prescribing of prophylactic antibiotics can reduce the frequency of corticosteroid-associated infections warrants further evaluation,” editorialists write (
pp. 429–31). “The pursuit of safer and more effective alternatives to corticosteroids should also continue, despite disappointing or conflicting results from prior studies of azathioprine, mycophenolate mofetil, and rituximab. The efficacy of non–drug-based therapies, including tonsillectomy or dietary manipulation, also merit more rigorous evaluation. From a study design perspective, the TESTING trial raises some important questions regarding how best to adjudicate risks and benefits when evaluating study outcomes. Although the decision to halt TESTING prematurely due to safety concerns was reasonable, the appropriateness of the prevailing practice for [data and safety monitoring committees (DSMCs)] to examine treatment-related adverse events in isolation from likely benefits deserves further consideration. Indeed, a recent statement from the Clinical Trials Transformation Initiative outlining recommendations for DSMCs indicated that ‘attempting to assess harm alone, without the context of clinical benefit, would, in most cases, be ill advised.’ Engagement of patient advocates in study design might also be informative, because patients are best poised to weigh the relative import of beneficial and harmful effects. Patient-reported outcomes should also receive increased focus in glomerular disease clinical trials, as recently advocated.” (M. M. O’Shaughnessy, moshaugh@stanford.edu)
Fees & Finances of Medical Specialty Boards: Medical specialty boards take in substantially more money than their services cost, according to an analysis of the Internal Revenue Service returns of 24 organizations (pp. 477–9). With mean fees for initial examinations averaging nearly $2,000 and mean maintenance of certification fees of $257 per year, the specialty boards reported substantial excess revenues as well as net balances: “In FY 2013, member boards reported $263 million (95% CI, $212 million–$249 million) in revenue and $239 million (95% CI, $218 million–$258 million) in expenses; a difference of $24 million (95% CI, $22 million–$26 million) in surplus. Examination fees accounted for 87.7% (95% CI, 82.4%-93.0%) of revenue and 21.3% (95% CI, 17.0%–25.6%) of expenditures, whereas officer and employee compensation and benefits accounted for 42.2% (95% CI, 36.9%–47.5%) of expenses.
“In total, the boards reported $701 million (95% CI, $644 million–$758 million) in assets and $65.6 million (95% CI, $60 million–$71 million) in liabilities (difference, $635 million (95% CI, $584 million–$687 million).…” (B. C. Drolet,

Angiotensin II for Vasodilatory Shock: In patients with vasodilatory shock unresponsive to high-dose vasopressors, angiotensin II increased blood pressure, investigators conclude (pp. 419–30). In the placebo-controlled, phase 3 Angiotensin II for the Treatment of High-Output Shock (ATHOS-3) study, 344 participants had these outcomes based on a primary end point of increased mean arterial pressure 3 hours after the start of infusion without an increase in the dose of background vasopressors: “The primary end point was reached by more patients in the angiotensin II group (114 of 163 patients, 69.9%) than in the placebo group (37 of 158 patients, 23.4%) (odds ratio, 7.95; 95% confidence interval [CI], 4.76 to 13.3; P <0.001). At 48 hours, the mean improvement in the cardiovascular Sequential Organ Failure Assessment (SOFA) score (scores range from 0 to 4, with higher scores indicating more severe dysfunction) was greater in the angiotensin II group than in the placebo group (−1.75 vs. −1.28, P = 0.01). Serious adverse events were reported in 60.7% of the patients in the angiotensin II group and in 67.1% in the placebo group. Death by day 28 occurred in 75 of 163 patients (46%) in the angiotensin II group and in 85 of 158 patients (54%) in the placebo group (hazard ratio, 0.78; 95% CI, 0.57 to 1.07; P = 0.12).” (R. Bellomo, rinaldo.bellomo@austin.org.au)
“The promise of a new class of vasopressor is appealing, and the results of the ATHOS-3 trial are encouraging,” editorialists conclude (
pp. 486–7). “We do, however, urge considerable thought regarding the rapidity with which this agent is advanced to the bedside and the decision as to which patients are the best candidates. There are still important questions to be answered, important subgroups to be analyzed, and important comparisons to be made.” (R. P. Dellinger)
Idarucizumab for Dabigatran Reversal: Reporting data on the full cohort of 503 participants in the Reversal Effects of Idarucizumab on Active Dabigatran (RE-VERSE AD) study, researchers report that “idarucizumab rapidly, durably, and safely reversed the anticoagulant effect of dabigatran” in emergency situations (pp. 431–41). Patients were categorized as requiring anticoagulant reversal for uncontrolled bleeding (group A) or an urgent procedure (group B). Results showed: “A total of 503 patients were enrolled: 301 in group A, and 202 in group B. The median maximum percentage reversal of dabigatran was 100% (95% confidence interval, 100 to 100), on the basis of either the diluted thrombin time or the ecarin clotting time. In group A, 137 patients (45.5%) presented with gastrointestinal bleeding and 98 (32.6%) presented with intracranial hemorrhage; among the patients who could be assessed, the median time to the cessation of bleeding was 2.5 hours. In group B, the median time to the initiation of the intended procedure was 1.6 hours; periprocedural hemostasis was assessed as normal in 93.4% of the patients, mildly abnormal in 5.1%, and moderately abnormal in 1.5%. At 90 days, thrombotic events had occurred in 6.3% of the patients in group A and in 7.4% in group B, and the mortality rate was 18.8% and 18.9%, respectively. There were no serious adverse safety signals.” (C. V. Pollack, Jr., charles.pollack@jefferson.edu)

Medication & CBT for Hypochondriasis: A study of 195 patients with hypochondriasis shows benefits of fluoxetine treatment but little advantage to combining the drug with cognitive–behavioral therapy (pp. 756–64). “New or more intensive approaches are needed,” the authors conclude after noting that 50% of patients had not responded to any of the study treatments at 24 weeks: “The predicted pattern of response was statistically significant, as shown by the following responder rates: joint treatment group, 47.2%; single active treatment group, 41.8%; and placebo group, 29.6%. Responder rates for each active treatment were not significantly different from the rate for placebo. Secondary analyses of the Whiteley Index as a continuous measure revealed that, compared with placebo, fluoxetine (but not CBT) was significantly more effective at week 24 in reducing hypochondriasis and had a significantly faster rate of improvement over 24 weeks. Fluoxetine also resulted in significantly less anxiety and better quality of life than placebo. Dropout rates did not differ between groups, and treatment-emergent adverse events were evenly distributed.” (B. A. Fallon)
Suicidal Behavior With Lithium & Valproate in Bipolar Disorder: Lithium should be considered for patients with bipolar disorder with possible suicidal ideation, according to data linking outcomes in multiple Swedish national registries (pp. 795–802). While noting that “risk for suicide is only one of the considerations when providing clinical care” of those with bipolar disorder, the investigators report these findings for 51,535 individuals with the condition in 2005–13: “During follow-up, 10,648 suicide-related events occurred. The incidence rate was significantly decreased by 14% during lithium treatment (hazard ratio 0.86, 95% confidence interval [CI] 0.78–0.95) but not during valproate treatment (hazard ratio 1.02, 95% CI 0.89–1.15). The difference in hazard ratios of suicide-related events between lithium and valproate was statistically significant. Estimates of the population attributable fraction suggested that 12% (95% CI 4%−20%) of suicide-related events could have been avoided if patients had taken lithium during the entire follow-up.” (J.

Testing in Low-Risk Penicillin Allergy Symptoms: At a pediatric emergency department, none of 100 children whose parents reported low-risk penicillin allergy symptoms had true penicillin allergy, researchers report (10.1542/peds.2017-0471). Penicillin allergy testing showed these results: “The median (interquartile range) age at testing was 9 years (5–12). The median (interquartile range) age at allergy diagnosis was 1 year (9 months–3 years). Rash (97 [97%]) and itching (63 [63%]) were the most commonly reported allergy symptoms. Overall, 100 children (100%; 95% confidence interval 96.4%–100%) were found to have negative results for penicillin allergy and had their labeled penicillin allergy removed from their medical record.” (D.

Neonatal Psychotropic, Opioid Drug Withdrawal: Among 201,275 pregnant women on public insurance in the U.S., the use of psychotropic medications in addition to opioids is common, an observational study shows, leading to an increasing risk for and severity of neonatal drug withdrawal (j3326). The study included a nationwide sample of pregnancies among women exposed to opioids around the time of delivery whose records were in the Medicaid Analytic eXtract for 2000–10: “The absolute risk for neonatal drug withdrawal ranged from 1.0% in infants exposed in utero to prescription opioids alone to 11.4% for those exposed to opioids co-prescribed with gabapentin. Among neonates exposed in utero to prescription opioids, the relative risk adjusted for propensity score was 1.34 (95% confidence interval 1.22 to 1.47) with concomitant exposure to antidepressants, 1.49 (1.35 to 1.63) with benzodiazepines, 1.61 (1.26 to 2.06) with gabapentin, 1.20 (0.95 to 1.51) with antipsychotics, and 1.01 (0.88 to 1.15) with [nonbenzodiazepine hypnotics]. In utero exposure to two or more psychotropic medications along with opioids was associated with a twofold increased risk of withdrawal (2.05, 1.77 to 2.37). The severity of the withdrawal seemed increased in neonates exposed to both opioids and psychotropic medications compared with opioids alone.” (K. F. Huybrechts, khuybrechts@bwh.harvard.edu)
“These findings suggest a clear need for a comprehensive, evidence informed strategy regarding opioid use in pregnancy,” editorialists write (
j3616). “To be effective, the strategy would specify opportunities for intervention in clinical and public health settings in all time periods related to pre-pregnancy, antepartum/prenatal, peripartum/perinatal, and postpartum/infancy. There remains a paucity of clinical guidance for obstetricians and pediatricians caring for the mother–child unit; development of a strategy will help to prioritize the development of specific evidence. As the U.S. opioid epidemic accelerates in complexity, there is an urgent need to focus resources on this issue, including expansion of research funding for drug safety in pregnancy and improvement of outcomes for mothers and infants affected by opioid use disorder, more funding for the prevention of the disorder, and an expansion of treatment options for affected mothers and their infants.” (S.

Electronic, Financial & Social Support After MI: In a 12-month study of patients who survived acute myocardial infarction (AMI), a “compound intervention integrating wireless pill bottles, lottery-based incentives, and social support did not significantly improve medication adherence or vascular readmission outcomes,” according to HeartStrong investigators (pp. 1093–101). Conducted in 2013–16, the study included 1,509 participants who were taking at least two of four study medications (statins, aspirin, beta-blockers, antiplatelet agents). Based on a primary outcome of time to first vascular rehospitalization or death, the medication adherence intervention produced these outcomes in comparison with usual care: “A total of 35.5% of participants were female (n = 536); mean (SD) age was 61.0 (10.3) years. There were no statistically significant differences between study arms in time to first rehospitalization for a vascular event or death (hazard ratio, 1.04; 95% CI, 0.71 to 1.52; P = .84), time to first all-cause rehospitalization (hazard ratio, 0.89; 95% CI, 0.73 to 1.09; P = .27), or total number of repeated hospitalizations (hazard ratio, 0.94; 95% CI, 0.60 to 1.48; P = .79). Mean (SD) medication adherence did not differ between control (0.42 [0.39]) and intervention (0.46 [0.39]) (difference, 0.04; 95% CI, −0.01 to 0.09; P = .10). Mean (SD) medical costs in 12 months following enrollment did not differ between control ($29,811 [$74,850]) and intervention ($24,038 [$66,915]) (difference, −$5,773; 95% CI, −$13,682 to $2,137; P = .15).” (K. G. Volpp, volpp70@wharton.upenn.edu)
Behavioral Approach to Improving Antimicrobial Prescribing: Addressing the “complex behavioral process” of changing antimicrobial prescribing can result in increased appropriateness of antimicrobial prescribing, researchers report (pp. 1130–8). In the Dutch Unique Method for Antimicrobial Stewardship (DUMAS) study, prescribers “were stimulated to choose interventions with higher potential for success based on a root cause analysis of inappropriate prescribing,” leading to these results: “A total of 1,121 patient cases with 700 antimicrobial prescriptions were assessed during the baseline period and 882 patient cases with 531 antimicrobial prescriptions during the intervention period. The mean antimicrobial appropriateness increased from 64.1% at intervention start to 77.4% at 12-month follow-up (+13.3%; relative risk, 1.17; 95% CI, 1.04-1.27), without a change in slope. No decrease in antimicrobial consumption was found.” The authors conclude, “Use of a behavioral approach preserving prescriber autonomy resulted in an increase in antimicrobial appropriateness sustained for at least 12 months. The approach is inexpensive and could be easily transferable to various health care environments.” (J. J. Sikkens, j.sikkens@vumc.nl)
Prescription Drug Price Rebates in Medicare Part D: In a special communication that details how rebates are lowering out-of-pocket costs for Part D beneficiaries but raising Medicare costs, authors propose policy alternatives that “reconfigure cost sharing to lower patient out-of-pocket costs and reduce cost shifting to Medicare” (pp. 1185–8): “The increasing cost of prescription drugs is a burden for patients and threatens the financial stability of the U.S. health care system. Rebates are a form of price concession paid by a pharmaceutical manufacturer to the health plan sponsor or the pharmacy benefit manager working on the plan’s behalf. Proponents argue that rebates result from vigorous negotiations that help lower overall drug costs. Critics argue that rebates have perversely increased the costs patients pay out of pocket, as well as the costs for Medicare as a whole. This special communication discusses how the availability of rebates for drugs covered by the Medicare Part D program may raise costs for patients and Medicare while increasing the profits of Part D plan sponsors and pharmaceutical manufacturers.” (S.

Levosimendan in Low Cardiac Output Syndrome: In the Levosimendan in Coronary Artery Revascularization trial, patients with low ejection fraction who were undergoing coronary artery bypass grafting with cardiopulmonary bypass did not have improved outcomes with levosimendan compared with placebo (pp. 548–56). Based on a composite end point of prolonged catecholamine infusion, use of left ventricular mechanical assist device, or renal replacement therapy, results at 13 French cardiac surgical centers showed the following: “Among 336 randomized patients (mean age, 68 years; 16% women), 333 completed the trial. The primary end point occurred in 87 patients (52%) in the levosimendan group and 101 patients (61%) in the placebo group (absolute risk difference taking into account center effect, −7% [95% CI, −17% to 3%]; P = .15). Predefined subgroup analyses found no interaction with ejection fraction less than 30%, type of surgery, and preoperative use of beta-blockers, intra-aortic balloon pump, or catecholamines. The prevalence of hypotension (57% vs 48%), atrial fibrillation (50% vs 40%), and other adverse events did not significantly differ between levosimendan and placebo.” (B.

Azithromycin & Airflow Decline–Free Survival After Allogeneic HSCT: A trial terminated early showed worse airflow decline–free survival with early administration of azithromycin in patients undergoing allogeneic hematopoietic stem cell transplant (HSCT), researchers report (pp. 557–66). The ALLOZITHRO parallel-group trial, conducted in 19 French academic transplant centers, compared azithromycin with placebo in participants aged 16 years or older who had undergone allogeneic HSCT for hematologic malignancy. A primary efficacy end point of airflow decline–free survival at 2 years after randomization produced these findings: “Thirteen months after enrollment, the independent data and safety monitoring board detected an unanticipated imbalance across blinded groups in the number of hematological relapses, and the treatment was stopped December 26, 2016. Among 480 randomized participants, 465 (97%) were included in the modified intention-to-treat analysis (mean age, 52 [SD, 14] years; 75 women [35%]). At the time of data cutoff, 104 patients (22%; 54 azithromycin vs 50 placebo) had experienced an airflow decline; 138 patients (30%) died (78 azithromycin vs 60 placebo). Two-year airflow decline–free survival was 32.8% (95% CI, 25.9%–41.7%) with azithromycin and 41.3% (95% CI, 34.1%–50.1%) with placebo (unadjusted hazard ratio [HR], 1.3; 95% CI, 1.02–1.70; P = .03). Of the 22 patients (5%) who experienced bronchiolitis obliterans syndrome, 15 (6%) were in the azithromycin group and 7 (3%) in the placebo group (P = .08). The azithromycin group had increased mortality, with a 2-year survival of 56.6% (95% CI, 50.2%–63.7%) vs 70.1% (95% CI, 64.2%–76.5%) in the placebo group (unadjusted HR, 1.5; 95% CI, 1.1–2.0; P = .02). In a post hoc analysis, the 2-year cumulative incidence of hematological relapse was 33.5% (95% CI, 27.3%–39.7%) with azithromycin vs 22.3% (95% CI, 16.4%–28.2%) with placebo (unadjusted cause-specific HR, 1.7; 95% CI, 1.2–2.4; P = .002).” (A.

FDA yesterday announced plans to pursue a strategic, new public health education campaign aimed at discouraging the use of e-cigarettes and other electronic nicotine delivery systems (ENDS) by kids. The agency plans to expand its “The Real Cost” public education campaign to include messaging to teens about the dangers of using these products this fall while developing a full-scale campaign to launch in 2018. These efforts are part of the agency’s new comprehensive plan for tobacco and nicotine regulation, as well as ongoing efforts to educate youth about and protect them from the dangers associated with using all tobacco products. It is the first time FDA will be using public health education to specifically target youth use of e-cigarettes or other ENDS.

Olaparib for Metastatic Breast Cancer With BRCA Mutation: Among 302 patients with HER2-negative metastatic breast cancer and a germline BRCA mutation, a phase 3 trial demonstrated efficacy of the an oral poly(adenosine diphosphate–ribose) polymerase inhibitor, compared with standard therapy (pp. 523–33). Olaparib 300 mg twice daily or standard therapy with a single chemotherapy agent of the physician’s choice produced these results based on a primary end point of progression-free survival: “Median progression-free survival was significantly longer in the olaparib group than in the standard-therapy group (7.0 months vs. 4.2 months; hazard ratio for disease progression or death, 0.58; 95% confidence interval, 0.43 to 0.80; P <0.001). The response rate was 59.9% in the olaparib group and 28.8% in the standard-therapy group. The rate of grade 3 or higher adverse events was 36.6% in the olaparib group and 50.5% in the standard-therapy group, and the rate of treatment discontinuation due to toxic effects was 4.9% and 7.7%, respectively.” (M.

Influenza Vaccine Effectiveness in 2015–16: The Influenza Vaccine Effectiveness Network reports data on the 2015–16 season in the U.S., showing overall lowering of influenza illness but ineffectiveness of the live attenuated vaccine (pp. 534–43). Results for patients aged 6 months or older who presented at ambulatory clinics in the network had these outcomes for acute respiratory illness: “Among 6,879 eligible participants, 1,309 (19%) tested positive for influenza virus, predominantly for A(H1N1)pdm09 (11%) and influenza B (7%). The effectiveness of the influenza vaccine against any influenza illness was 48% (95% confidence interval [CI], 41 to 55; P <0.001). Among children 2 to 17 years of age, the inactivated influenza vaccine was 60% effective (95% CI, 47 to 70; P <0.001), and the live attenuated vaccine was not observed to be effective (vaccine effectiveness, 5%; 95% CI, −47 to 39; P = 0.80). Vaccine effectiveness against A(H1N1)pdm09 among children was 63% (95% CI, 45 to 75; P <0.001) for the inactivated vaccine, as compared with −19% (95% CI, −113 to 33; P = 0.55) for the live attenuated vaccine.” (M.

NAD Deficiency, Congenital Malformations & Niacin Supplementation: Seeking to identify a mechanism causing common co-occurring phenotypic congenital malformations, researchers showed that disruptions in nicotinomide synthesis were linked to birth defects in people and mice and that niacin supplementation during pregnancy prevented the problems in mice progeny (pp. 544–52). Genomic sequencing in families of individuals with multiple congenital malformations, assays of in vitro enzyme activity and metabolites in plasma of patients, and engineered mouse models showed the following: “Variants were identified in two genes that encode enzymes of the kynurenine pathway, 3-hydroxyanthranilic acid 3,4-dioxygenase (HAAO) and kynureninase (KYNU). Three patients carried homozygous variants predicting loss-of-function changes in the HAAO or KYNU proteins (HAAO p.D162*, HAAO p.W186*, or KYNU p.V57Efs*21). Another patient carried heterozygous KYNU variants (p.Y156* and p.F349Kfs*4). The mutant enzymes had greatly reduced activity in vitro. Nicotinamide adenine dinucleotide (NAD) is synthesized de novo from tryptophan through the kynurenine pathway. The patients had reduced levels of circulating NAD. Defects similar to those in the patients developed in the embryos of Haao-null or Kynu-null mice owing to NAD deficiency. In null mice, the prevention of NAD deficiency during gestation averted defects.” (S. L. Dunwoodie, s.dunwoodie@victorchang.edu.au)
Acute Respiratory Distress Syndrome: Progress in defining and recognizing acute respiratory distress syndrome (ARDS) is reviewed (pp. 562–72): “We now recognize that ARDS, like asthma, is a syndrome characterized by substantial heterogeneity. A much better understanding of the biologic and genetic underpinnings of the subphenotypes of ARDS should lead the way to more targeted therapies. Until then, ICU practices that prevent ARDS, early and effective treatment of the insults leading to ARDS, and lung-protective ventilation and sensible fluid management remain the essential elements for good outcomes.” (B.

Seminal Clearance of HIV With Antiretroviral Agents: Compared with ritonavir-boosted darunavir (DRVrtv), rilpivirine (RPV) or cobicistat-boosted elvitegravir (EVGcobi) more quickly achieve undetectable HIV load in seminal plasma (SP) when administered with tenofovir-disoproxil fumarate (DF) plus emtricitabine, researchers report (pp. 551–6). A phase 2, randomized, open-label study of treatment-naive patients with HIV showed the following: “In SP, the HIV-RNA decay rate with RPV was as fast as with EVGcobi; by week 12, all participants in the RPV and the EVGcobi groups reached an undetectable viral load but only 58.3% in the DRVrtv arm (P = .003). The highest SP/BP drug concentration ratio was for EVG (0.43), followed-up by RPV (0.19), and DRV (0.10). For both EVG and RPV, the SP concentrations exceeded >2-fold the protein binding-adjusted [90% effective concentrations (EC90)] for wild-type HIV-1; for DRV, only 33.7% of the SP showed concentrations above the protein binding-adjusted EC90.” (A.

Influenza-Associated Neurological Disease in Children: Longitudinal surveillance data from Australia show that influenza-associated encephalitis/encephalopathy (IAE) is an important cause of pediatric acute neurological disease, one associated with high morbidity and mortality (pp. 653–60). In 2013 through 2015, children hospitalized with seasonal influenza often had influenza–associated neurological disease (IAND): “Over 3 influenza seasons, we identified 54 cases of IAND at 2 tertiary children’s hospitals from Australia that accounted for 7.6% of hospitalized influenza. These included 10 cases of IAE (1.4% hospitalized influenza). The mean annual incidence of IAE among Australian children (aged ≤14 years) was 2.8 per 1,000,000. The spectrum of IAND was broad and included IAE (n = 10) including distinct acute encephalopathy syndromes, simple febrile seizures (n = 14), other seizures (n = 16), acute ataxia (n = 4), and other subacute syndromes (transverse myelitis [n = 1], opsoclonus myoclonus [n = 1]). Two-thirds of children with IAND were aged ≤4 years; less than half had preexisting neurological disease or other risk factors for severe influenza. IAE caused death or neurological morbidity in half of cases.” (P. N. Britton)

Falls Among Women With Chemo-Induced Peripheral Neuropathy: Among 512 women cancer survivors, those who had chemotherapy-induced peripheral neuropathy (CIPN) frequently reported persistence of symptoms years later, a study shows, indicating a need to assess patients for the condition earlier in the clinical pathway and develop strategies to limit symptom progression and improve function (pp. 2604–12): “After an average of 6 years after treatment, 47% of women still reported symptoms of CIPN. CIPN+ had significantly worse self-report and objectively measured function than did CIPN−, with the exception of maximal leg strength and base of support during a usual walk. Gait was slower among CIPN+, with those women taking significantly more, but slower and shorter, steps than did CIPN− (all P < .05). CIPN+ reported significantly more disability and 1.8 times the risk of falls compared with CIPN− (P < .0001). Increasing symptom severity was linearly associated with worsening function, increasing disability, and higher fall risk (all P < .05).” (K. M. Winters-Stone, wintersk@ohsu.edu)
“Until [risk classification and prevention strategies are available], the current evidence suggests the need for a broader perspective and altered clinical pathways to facilitate improved CIPN symptom management that addresses balance and functional mobility deficits both during active cancer treatment and through survivorship,” writes an editorialist (

Influenza Vaccine Delivered by Microneedle Patch: In a phase 1 trial, a dissolvable microneedle patch was used successfully for administration of the 2014–15 seasonal influenza vaccine in adults aged 18–49 years, researchers report (pp. 649–58). “Robust antibody responses” were found in the TIV-MNP 2015 study of 100 participants who were randomized to inactivated influenza vaccine delivered by a health professional using the microneedle patch or intramuscular injection, a placebo by microneedle patch administered by a health professional, or the vaccine patch administered by the participants. Results showed: “There were no treatment-related serious adverse events, no treatment-related unsolicited grade 3 or higher adverse events, and no new-onset chronic illnesses. Among vaccinated groups (vaccine via health-care worker administered microneedle patch or intramuscular injection, or self-administered microneedle patch), overall incidence of solicited adverse events (n = 89 vs n = 73 vs n = 73) and unsolicited adverse events (n = 18 vs n = 12 vs n = 14) were similar. Reactogenicity was mild, transient, and most commonly reported as tenderness (15 [60%] of 25 participants [95% CI 39–79]) and pain (11 [44%] of 25 [24–65]) after intramuscular injection; and as tenderness (33 [66%] of 50 [51–79]), erythema (20 [40%] of 50 [26–55]), and pruritus (41 [82%] of 50 [69–91]) after vaccination by microneedle patch application. The geometric mean [antibody] titres were similar at day 28 between the microneedle patch administered by a health-care worker versus the intramuscular route for the H1N1 strain (1197 [95% CI 855–1675] vs 997 [703–1415]; p = 0.5), the H3N2 strain (287 [192–430] vs 223 [160–312]; p = 0.4), and the B strain (126 [86–184] vs 94 [73–122]; p = 0.06). Similar geometric mean titres were reported in participants who self-administered the microneedle patch (all p >0.05). The seroconversion percentages were significantly higher at day 28 after microneedle patch vaccination compared with placebo (all p <0.0001) and were similar to intramuscular injection (all p >0.01).” (N.

Azithromycin in Adults With Persistent Uncontrolled Asthma: In the AMAZES trial, 420 participants with persistent symptomatic asthma had “fewer asthma exacerbations and improved quality of life when treated with oral azithromycin for 48 weeks,” investigators write (pp. 659–68). Those included in the trial were adults with symptomatic asthma despite current use of inhaled corticosteroid and long-acting bronchodilator, and who had no hearing impairment or abnormal prolongation of the corrected QT interval. Treatment with azithromycin 500 mg or placebo three times per week for 48 weeks yielded these results: “Azithromycin reduced asthma exacerbations (1.07 per patient–year [95% CI 0.85–1.29]) compared with placebo (1.86 per patient–year [1.54–2.18]; incidence rate ratio [IRR] 0.59 [95% CI 0.47–0.74]; p <0.0001). The proportion of patients experiencing at least one asthma exacerbation was reduced by azithromycin treatment (127 [61%] patients in the placebo group vs 94 [44%] patients in the azithromycin group, p <0.0001). Azithromycin significantly improved asthma-related quality of life (adjusted mean difference, 0.36 [95% CI 0.21–0.52]; p = 0.001). Diarrhoea was more common in azithromycin-treated patients (72 [34%] vs 39 [19%]; p = 0.001).” (P. G. Gibson, peter.gibson@hnehealth.nsw.gov.au)

Therapeutic Effects of Plant-Based Cannabis: Two reviews and an editorial examine evidence of benefits and harms associated with use of plant-based cannabis for chronic pain and posttraumatic stress disorder (PTSD).
Neuropathic pain may be an appropriate therapeutic target for plant-based cannabis products, a systematic review shows, but data are insufficient to evaluate use in other forms of chronic pain (
10.7326/M17-0155): “From 27 chronic pain trials, there is low-strength evidence that cannabis alleviates neuropathic pain but insufficient evidence in other pain populations. According to 11 systematic reviews and 32 primary studies, harms in general population studies include increased risk for motor vehicle accidents, psychotic symptoms, and short-term cognitive impairment. Although adverse pulmonary effects were not seen in younger populations, evidence on most other long-term physical harms, in heavy or long-term cannabis users, or in older populations is insufficient.” (S. M. Nugent, Shannon.Nugent@va.gov)
Evidence is lacking for assessing cannabis use in patients with PTSD, researchers report, but results of ongoing studies should shed light on the issue (
10.7326/M17-0477). Available studies provide “very scant evidence with medium to high risk of bias,” the authors conclude, adding these details: “Two systematic reviews, 3 observational studies, and no randomized trials were found. The systematic reviews reported insufficient evidence to draw conclusions about benefits and harms. The observational studies found that compared with nonuse, cannabis did not reduce PTSD symptoms. Studies had medium and high risk of bias, and overall evidence was judged insufficient. Two randomized trials and 6 other studies examining outcomes of cannabis use in patients with PTSD are ongoing and are expected to be completed within 3 years.” (M. E. O’Neil, maya.oneil@va.gov)
“The conclusions of both systematic reviews largely echo the National Academies of Sciences, Engineering, and Medicine’s recent comprehensive review on these and other health effects of cannabis, suggesting a growing consensus in the field,” an editorialist concludes (
10.7326/M17-1713). “Little high-quality evidence exists from which to draw firm conclusions about the efficacy of cannabis and cannabinoid products for treating pain and PTSD. Although several well-designed trials are under way to address this critical issue, to some degree the horse is out of the barn—and unlikely to return. Even if future studies reveal a clear lack of substantial benefit of cannabis for pain or PTSD, legislation is unlikely to remove these conditions from the lists of indications for medical cannabis. It will be up to front-line practicing physicians to learn about the harms and benefits of cannabis, educate their patients on these topics, and make evidence-based recommendations about using cannabis and related products for various health conditions. In parallel, the research community must pursue high-quality studies and disseminate the results to clinicians and the public. In this context, these reviews are must-reads for all physicians, especially those practicing in states where medical cannabis is legal.” (S. Patel, Sachin.patel@vanderbilt.edu)
Hormone Therapy in Transgender Adults: Lack of research into cardiovascular disease (CVD) among transgender adults muddles the safety of use of cross-sex hormone therapy (CSHT), according to authors of a narrative review (pp. 256–67): “For transgender adults, CSHT has been associated with the potential for worsening CVD risk factors (such as blood pressure elevation, insulin resistance, and lipid derangements), although these changes have not been associated with increases in morbidity or mortality in transgender men receiving CSHT. For transgender women, CSHT has known thromboembolic risk, and lower-dose transdermal estrogen formulations are preferred over high-dose oral formulations. In addition, many studies of transgender adults focus predominantly on younger persons, limiting the generalizability of CSHT in older transgender adults. The lack of randomized controlled trials comparing various routes and formulations of CSHT, as well as the paucity of prospective cohort studies, limits knowledge of any associations between CSHT and CVD.” (C.

Evidence v. Access in FDA Decisions: Researchers and an editorialist examine quality and other characteristics of studies used to support FDA decisions regarding medical devices and medications considered on an accelerated basis.
Medications granted accelerated approval by FDA in 2009–13 often but not always had efficacy confirmed in postapproval studies, but the trials often had weaknesses such as use of surrogate outcomes that were present in preapproval research (
pp. 626–36). Using publicly available documents, investigators found the following for 22 drugs with 24 indications (19 of which were oncologic): “A total of 30 preapproval studies supported the 24 indications. The median number of participants enrolled in the preapproval studies was 132 (interquartile range, 89-224). Eight studies (27%) included fewer than 100 participants and 20 (67%) included fewer than 200. At a minimum 3 years of follow-up, 19 of 38 (50%) required confirmatory studies were completed, including 18 published reports. Twenty-five of the 38 (66%) examined clinical efficacy, 7 (18%) evaluated longer follow-up, and 6 (16%) focused on safety The proportion of studies with randomized designs did not differ before and after accelerated approval (12/30 [40%] vs 10/18 [56%]; difference, 16%; 95% CI, −15% to 46%; P = .31). Postapproval requirements were completed and demonstrated efficacy in 10 of 24 indications (42%) on the basis of trials that evaluated surrogate measures. Among the 14 of 24 indications (58%) that had not yet completed all requirements, at least 1 of the confirmatory studies failed to demonstrate clinical benefit in 2 (8%), were terminated in 2 (8%), and were delayed by more than 1 year in 3 (13%). Studies were progressing according to target timelines for the remaining 7 indications (29%). Clinical benefit had not yet been confirmed for 8 indications that had been initially approved 5 or more years prior.” (H. Naci, Ph.naci@lse.ac.uk)
“Among clinical studies used to support FDA approval of high-risk medical device modifications, fewer than half were randomized, blinded, or controlled, and most primary outcomes were based on surrogate end points,” a second research team reports (
pp. 619–25). “These findings suggest that the quality of studies and data evaluated to support approval by the FDA of modifications of high-risk devices should be improved.” (R. F. Redberg, rita.redberg@ucsf.edu)
Referring to digital systems now available that link usage data with clinical end points, an editorialist concludes, “It is now time to seriously consider how to use these increasingly robust data and analytic capabilities and more efficient prospective research systems to deal with the issues raised by these articles” (
pp. 614–6). “Much of the objection to [randomized controlled trials (RCTs)] arises from the substantial cost and inflexibility of ‘traditional’ regulatory trials. But as technological improvements and nationally and globally connected networks of health systems make it feasible to conduct high-quality, low-cost RCTs and to continuously monitor product performance, the impediments to progress are mostly those built into the culture of medicine and health care.” (R. M. Califf, robert.califf@duke.edu)
Intensive Lifestyle Intervention in Type 2 Diabetes: Beneficial but not significant results followed a lifestyle intervention among 98 Danish adults whose type 2 diabetes of less than 10 years’ duration was being managed without insulin therapy, a study shows (pp. 637–46). Participants assigned to an exercise/weight loss intervention had these outcomes in comparison with those on standardized, target-driven medical therapy: “From baseline to 12-month follow-up, the mean HbA1c level changed from 6.65% to 6.34% in the lifestyle group and from 6.74% to 6.66% in the standard care group (mean between-group difference in change of −0.26% [95% CI, −0.52% to −0.01%]), not meeting the criteria for equivalence (P = .15). Reduction in glucose-lowering medications occurred in 47 participants (73.5%) in the lifestyle group and 9 participants (26.4%) in the standard care group (difference, 47.1 percentage points [95% CI, 28.6-65.3]). There were 32 adverse events (most commonly musculoskeletal pain or discomfort and mild hypoglycemia) in the lifestyle group and 5 in the standard care group.” (M.

Low-Dose Aspirin for Preeclampsia: In 1,776 women with high-risk singleton pregnancies, treatment with low-dose aspirin lowered the incidence of preterm preeclampsia in comparison with placebo, report Collaborative Low-Dose Aspirin Study in Pregnancy (CLASP) investigators (pp. 613–22). Administered from early in pregnancy (11–14 weeks’ gestation) until the 36th week, aspirin 150 mg/d produced these outcomes on an intention-to-treat basis: “A total of 152 women withdrew consent during the trial, and 4 were lost to follow up, which left 798 participants in the aspirin group and 822 in the placebo group. Preterm preeclampsia occurred in 13 participants (1.6%) in the aspirin group, as compared with 35 (4.3%) in the placebo group (odds ratio in the aspirin group, 0.38; 95% confidence interval, 0.20 to 0.74; P = 0.004). Results were materially unchanged in a sensitivity analysis that took into account participants who had withdrawn or were lost to follow-up. Adherence was good, with a reported intake of 85% or more of the required number of tablets in 79.9% of the participants. There were no significant between-group differences in the incidence of neonatal adverse outcomes or other adverse events.” (K. H. Nicolaides, kypros@fetalmedicine.com)
“On the basis of the 2014 systematic review, the [U.S. Preventive Services Task Force] currently recommends daily low-dose (81 mg) aspirin therapy beginning at 12 weeks of gestation in patients who are considered to be at ‘high risk for preeclampsia’ according to medical and obstetrical criteria,” editorialists write (
pp. 613–22). “The American College of Obstetricians and Gynecologists has endorsed these guidelines. Taken together with findings from other studies, [these] findings … support recommendations for the use of prophylactic low-dose aspirin in high-risk women. However, the effects of aspirin on several clinically important, preeclampsia-associated complications — in particular, perinatal mortality — remain unproved.” (M. F. Greene)
Canagliflozin & Outcomes in Type 2 Diabetes: While cardiovascular and renal outcomes were improved among patients treated with canagliflozin in two clinical trials, the risk of amputation was increased (pp. 644–57). The CANVAS program included 10,142 participants with type 2 diabetes and high cardiovascular risk. Based on a primary outcome of composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke, results showed: “The mean age of the participants was 63.3 years, 35.8% were women, the mean duration of diabetes was 13.5 years, and 65.6% had a history of cardiovascular disease. The rate of the primary outcome was lower with canagliflozin than with placebo (occurring in 26.9 vs. 31.5 participants per 1,000 patient–years; hazard ratio, 0.86; 95% confidence interval [CI], 0.75 to 0.97; P <0.001 for noninferiority; P = 0.02 for superiority). Although on the basis of the prespecified hypothesis testing sequence the renal outcomes are not viewed as statistically significant, the results showed a possible benefit of canagliflozin with respect to the progression of albuminuria (hazard ratio, 0.73; 95% CI, 0.67 to 0.79) and the composite outcome of a sustained 40% reduction in the estimated glomerular filtration rate, the need for renal-replacement therapy, or death from renal causes (hazard ratio, 0.60; 95% CI, 0.47 to 0.77). Adverse reactions were consistent with the previously reported risks associated with canagliflozin except for an increased risk of amputation (6.3 vs. 3.4 participants per 1,000 patient–years; hazard ratio, 1.97; 95% CI, 1.41 to 2.75); amputations were primarily at the level of the toe or metatarsal.” (B. Neal, bneal@georgeinstitute.org.au)
Reference Pricing & Drug Selection: Use of reference pricing for medications — payment of a fixed amount based on indication — has the potential to change drug selection and spending for patients covered by employment-based insurance, an analysis shows (pp. 658–65). Over 18 months when an employee group had reference pricing, employer spending fell by $1.34 million for 1.12 million prescriptions, while patient copayments rose by $120,000. (J. C.

Off-Label Antipsychotic Prescribing to Older Veterans: While prescribing of second-generation antipsychotics (SGAs) to older veterans with posttraumatic stress disorder (PTSD) has declined, “prescribing an SGA to those with dementia remained consistently higher than for those with PTSD alone and is problematic given the high prevalence of medical comorbidities in this aging population coupled with the lack of compelling evidence for effectiveness of SGAs in individuals with dementia,” investigators conclude (pp. 1789–95). National VA data for 2004–09 show these prescribing patterns : “SGA prescribing declined annually from 7.0% to 5.1% of elderly veterans with PTSD without dementia and 13.2% to 8.9% in those with dementia; findings over time consistently indicated that veterans with PTSD and dementia had at least twice the odds of being prescribed an SGA as those without PTSD (odds ratios 2.03 (95% confidence interval (CI) = 1.82–2.26) to 2.33 (95% CI = 2.10–2.58).” (T. P. Semla, todd.semla@va.gov)
Antibiotic Prescribing Pathway for Presumed UTIs in Nursing Homes: At 31 North Carolina nursing homes (NHs), 260 randomly selected cases of residents being treated for presumed urinary tract infections (UTIs) were more influenced by nonspecific signs and symptoms than urinary-tract–specific ones, researchers report (pp. 1719–25). Antibiotics were rarely stopped, with some used for “overly long periods” the authors conclude, adding these details uncovered in chart reviews: “Of 260 cases, 60% had documented signs/symptoms of the presenting illness and 15% met the Loeb criteria [for initiation of antibiotics]. Acute mental status change was the most commonly documented sign/symptom (24%). NH providers (81%) were the most common prescribers and ciprofloxacin (32%) was the most commonly prescribed antibiotic. Fourteen percent of presumed UTI cases included a white blood cell count, 71% included a urinalysis, and 72% had a urine culture. Seventy-five percent of cultures grew at least one organism with ≥100,000 colony-forming units/milliliter and 12% grew multi-drug resistant organisms; 28% of antibiotics were prescribed for more than 7 days, and 7% of cases had a subsequent death, emergency department visit, or hospitalization within 7 days.” (C.

Urinary Tract Dysbiosis: Rather than the “ambiguous, expansive, overused diagnosis” of urinary tract infection (UTI), the term urinary tract dysbiosis “might encourage mindful study of the relationships among host, aging, microbiome, disease, and antibiotic treatment,” a Special Article author writes (pp. 1650–5): “‘Significant bacteriuria,’ central to most definitions of ‘UTI,’ has little significance in identifying individuals who will benefit from treatment. ‘Urinary symptoms’ are similarly uninformative. Neither criterion is well defined. Bacteriuria and symptoms remit and recur spontaneously. Treatment is standard for acute uncomplicated cystitis and common for asymptomatic bacteriuria, but definite benefits are few. Treatment for ‘UTI’ in older adults with delirium and bacteriuria is widespread but no evidence supports the practice, and expert opinion opposes it.…
“Sensitive diagnostic tests now demonstrate that healthy urinary tracts host a ubiquitous, complex microbial community. Recognition of this microbiome, largely undetectable using standard agar-based cultures, offers a new perspective on ‘UTI.’ Everyone is bacteriuric.…
“Mindful decisions about antibiotic use will require a far better understanding of how pathogenicity arises within microbial communities. It is likely that public education and meaningful informed-consent discussions about antibiotic treatment of bacteriuria, emphasizing potential harms and uncertain benefits, would reduce overtreatment.” (T.

Management of Non-ST-Elevation Acute Coronary Syndrome: Using a meta-analysis to identify the optimal timing of invasive management of patients with non-ST-elevation acute coronary syndromes (NSTE-ACS), authors found that only high-risk patients had lower mortality with earlier interventions and even in those patients, statistics were inconclusive (pp. 737–46). The overall dataset showed no mortality difference between early and late invasive strategies, as show in these findings: “We included eight trials (n = 5,324 patients) with a median follow-up of 180 days (IQR 180–360). Overall, there was no significant mortality reduction in the early invasive group compared with the delayed invasive group HR 0.81, 95% CI 0.64–1.03; p = 0.0879). In pre-specified analyses of high-risk patients, we found lower mortality with an early invasive strategy in patients with elevated cardiac biomarkers at baseline (HR 0.761, 95% CI 0.581–0.996), diabetes (0.67, 0.45–0.99), a GRACE risk score more than 140 (0.70, 0.52–0.95), and aged 75 years older (0.65, 0.46–0.93), although tests for interaction were inconclusive.” (H.

Fibrinolytics in ST-Segment Elevation Myocardial Infarction: Outcomes differ among various fibrinolytic regimens available for reperfusion therapy in patients with ST-segment elevation myocardial infarction (STEMI) in resource-scarce settings, researchers report (pp. 747–59). A network meta-analysis based on a systematic review of randomised controlled trials showed these outcomes based on a primary efficacy outcome of all-cause mortality within 30–35 days and a primary safety outcome of major bleeding: “A total of 40 eligible studies involving 128,071 patients treated with 12 different fibrinolytic regimens were assessed. Compared with accelerated infusion of alteplase with parenteral anticoagulants as background therapy, streptokinase and non-accelerated infusion of alteplase were significantly associated with an increased risk of all-cause mortality (risk ratio [RR] 1.14 [95% CI 1.05–1.24] for streptokinase plus parenteral anticoagulants; RR 1.26 [1.10–1.45] for non-accelerated alteplase plus parenteral anticoagulants). No significant difference in mortality risk was recorded between accelerated infusion of alteplase, tenecteplase, and reteplase with parenteral anticoagulants as background therapy. For major bleeding, a tenecteplase-based regimen tended to be associated with lower risk of bleeding compared with other regimens (RR 0.79 [95% CI 0.63–1.00]). The addition of glycoprotein IIb or IIIa inhibitors to fibrinolytic therapy increased the risk of major bleeding by 1.27–8.82-times compared with accelerated infusion alteplase plus parenteral anticoagulants (RR 1.47 [95% CI 1.10–1.98] for tenecteplase plus parenteral anticoagulants plus glycoprotein inhibitors; RR 1.88 [1.24–2.86] for reteplase plus parenteral anticoagulants plus glycoprotein inhibitors).” (N.

Precision Medicine Needed for Inhaled Corticosteroids in COPD: A precision medicine approach should be used in management of inhaled corticosteroid (ICS) therapy in patients with chronic obstructive pulmonary disorder (COPD), according to authors of an editorial (pp. 227–31). “The excessive use of ICS in the treatment of COPD, currently estimated to be given to >70% of patients, could be reduced to target those patients who would receive greater benefit than harm,” the authors write. Based on their analysis showing that treatment of COPD with a long-acting beta-agonist (LABA) combined with an ICS instead of an LABA alone for 1 year will prevent 1 patient from having a COPD exacerbation but cause 2 patients to develop severe pneumonia, the authors conclude, “For the estimated 8 million American patients with COPD treated with ICS, … a precision medicine approach could provide a net benefit to an estimated 2 million who respond to these drugs by reducing hospitalizations by 60,000 yearly. Furthermore, it would protect the remaining 6 million from the needless harms of these drugs in the absence of any or trivial benefit, preventing an estimated 120,000 patients from being hospitalized unnecessarily for pneumonia yearly.” (S. Suissa, samy.suissa@mcgill.ca)
Clinical Characteristics of Pertussis-Associated Cough: Symptoms of pertussis differ between adults and children, according to a systematic review and meta-analysis (pp. 353–67). “In adult patients, the presence of whooping or posttussive vomiting should rule in a possible diagnosis of pertussis, whereas the lack of a paroxysmal cough or the presence of fever should rule it out,” the group concludes. “In children, posttussive vomiting is much less helpful as a clinical diagnostic test.” (A.

Atorvastatin in Patients With Bronchiectasis: Reduction of systemic inflammation by atorvastatin was beneficial in patients with bronchiectasis who were infected with Pseudomonas aeruginosa, improving their quality of life, a study shows (pp. 368–78). In a double-blind crossover trial of 27 patients, atorvastatin 80 mg daily for 3 months produced these outcomes in comparison with placebo: “Atorvastatin did not significantly improve the primary end point of cough as measured by the Leicester Cough Questionnaire (mean difference, 1.92; 95% CI for difference, –0.57-4.41; P = .12). However, atorvastatin treatment resulted in an improved St. Georges Respiratory Questionnaire (–5.62 points; P = .016) and reduced serum levels of CXCL8 (P = .04), tumor necrosis factor (P = .01), and intercellular adhesion molecule 1 (P = .04). There was a trend toward improvement in serum C-reactive protein and serum neutrophil counts (P = .07 and P = .06, respectively). We demonstrated in vitro that atorvastatin 10 μM reduced formyl-methionyl-leucyl phenylalanine-induced upregulation of CD11b expression and changes in calcium flux, reflecting an ability to decrease neutrophil activation.” (P.

Blood Pressure, Dialysis & Mortality: In an observational study of 17,729 U.S. veterans transitioning to maintenance dialysis therapy in 2007–11, investigators conclude that “lower predialysis [systolic blood pressure (SBP)] is associated with higher all-cause mortality in the immediate postdialysis period” (pp. 207–17). “Predialysis [diastolic blood pressure] showed no consistent association with postdialysis mortality. Further studies are needed to clarify ideal predialysis SBP levels among incident dialysis patients as a potential means to improve the excessively high early dialysis mortality.” (C. P.

Natriuretic Peptide–Guided Therapy in Heart Failure With Reduced Ejection Fraction: In the Guiding Evidence Based Therapy Using Biomarker Intensified Treatment in Heart Failure (GUIDE-IT) study, high-risk patients whose drug therapy was adjusted based on natriuretic peptide levels had no better outcomes than those managed with usual care, researchers report (pp. 713–20). Study participants, all with heart failure (HF) and reduced ejection fraction (HFrEF), had these outcomes: “The data and safety monitoring board recommended stopping the study for futility when 894 (median age, 63 years; 286 [32%] women) of the planned 1,100 patients had been enrolled with follow-up for a median of 15 months. The primary end point occurred in 164 patients (37%) in the biomarker-guided group and 164 patients (37%) in the usual care group (adjusted hazard ratio [HR], 0.98; 95% CI, 0.79–1.22; P = .88). Cardiovascular mortality was 12% (n = 53) in the biomarker-guided group and 13% (n = 57) in the usual care group (HR, 0.94; 95% CI; 0.65–1.37; P = .75). None of the secondary end points nor the decreases in the NT-proBNP levels achieved differed significantly between groups.” (G. M. Felker, michael.felker@duke.edu)
“There is a critical need for greater focus on achieving guideline-directed target dosing of guideline-directed therapies via focused quality measures, heart failure disease management programs, and performance improvement systems,” editorialists write (
pp. 707–8). “As demonstrated in the GUIDE-IT trial published in this issue of JAMA, serial monitoring of natriuretic peptide biomarkers do not appear to add incremental value to such efforts.” (G. C. Fonarow, gfonarow@mednet.ucla.edu)
Oral Prednisolone in Nonasthmatic Lower Respiratory Tract Infection: “Oral corticosteroids should not be used for acute lower respiratory tract infection symptoms in adults without asthma because they do not reduce symptom duration or severity,” conclude authors of a 401-patient study (pp. 721–30). At 54 family practices in England, adults with acute cough and 1 or more lower respiratory tract symptoms not requiring immediate antibiotic treatment and with no history of chronic pulmonary disease or use of asthma medication in the past 5 years had these outcomes when randomized to prednisolone 40 mg or placebo once daily for 5 days: “Among the 398 patients with baseline data (mean age, 47 [SD, 16.0] years; 63% women; 17% smokers; 77% phlegm; 70% shortness of breath; 47% wheezing; 46% chest pain; 42% abnormal peak flow), 334 (84%) provided cough duration and 369 (93%) symptom severity data. Median cough duration was 5 days (interquartile range [IQR], 3–8 days) in the prednisolone group and 5 days (IQR, 3–10 days) in the placebo group (adjusted hazard ratio, 1.11; 95% CI, 0.89–1.39; P = .36 at an alpha = .05). Mean symptom severity was 1.99 points in the prednisolone group and 2.16 points in the placebo group (adjusted difference, −0.20; 95% CI, −0.40 to 0.00; P = .05 at an alpha = .001). No significant treatment effects were observed for duration or severity of other acute lower respiratory tract infection symptoms, duration of abnormal peak flow, antibiotic use, or nonserious adverse events. There were no serious adverse events.” (A. D. Hay, alastair.hay@bristol.ac.uk)
Cost-effectiveness Analysis of PCSK9 Inhibitors: Even considering new evidence regarding reduction of major adverse cardiovascular events (MACE) by evolocumab, PCSK9 inhibitor use in patients with atherosclerotic cardiovascular disease remains not cost-effective at 2017 prices, according to a research letter (pp. 748–50). Updating 2015 figures, investigators found these results for 8.9 million U.S. adults meeting FOURIER criteria: “Adding PCSK9 inhibitors to statins was estimated to prevent 2,893,500 more MACE compared with adding ezetimibe, at an [incremental cost-effectiveness ratio (ICER; incremental health care costs per quality-adjusted life–year [QALY] gained)] of $450,000/QALY (80% uncertainty interval, $301,000–$787,000). Reducing annual drug costs by 71% (to ≤$4,215) would be needed for PCSK9 inhibitors to be cost-effective at a threshold of $100,000/QALY. Assuming no direct effect on cardiovascular death as observed in FOURIER, the ICER increased to $1,795,000/QALY.” (K. Bibbins-Domingo, kirsten.bibbins-domingo@ucsf.edu)

Degludec Outcomes in Type 2 Diabetes: Among 7,637 participants with type 2 diabetes in the DEVOTE study who were at high risk for cardiovascular events, insulin “degludec was noninferior to [insulin] glargine with respect to the incidence of major cardiovascular events,” investigators conclude (pp. 723–32). Insulin degludec, an ultralong-acting, once-daily basal insulin, or insulin glargine U100 was administered once daily between dinner and bedtime in this treat-to-target trial, with these results: “Of the patients who underwent randomization, 6,509 (85.2%) had established cardiovascular disease, chronic kidney disease, or both. At baseline, the mean age was 65.0 years, the mean duration of diabetes was 16.4 years, and the mean (± SD) glycated hemoglobin level was 8.4 ± 1.7%; 83.9% of the patients were receiving insulin. The primary [efficacy] outcome occurred in 325 patients (8.5%) in the degludec group and in 356 (9.3%) in the glargine group (hazard ratio, 0.91; 95% confidence interval, 0.78 to 1.06; P <0.001 for noninferiority). At 24 months, the mean glycated hemoglobin level was 7.5 ± 1.2% in each group, whereas the mean fasting plasma glucose level was significantly lower in the degludec group than in the glargine group (128 ± 56 vs. 136 ± 57 mg per deciliter, P <0.001). Prespecified adjudicated severe hypoglycemia occurred in 187 patients (4.9%) in the degludec group and in 252 (6.6%) in the glargine group, for an absolute difference of 1.7 percentage points (rate ratio, 0.60; P <0.001 for superiority; odds ratio, 0.73; P <0.001 for superiority). Rates of adverse events did not differ between the two groups.” (S. P. Marso, smarso@gmail.com)
Intensive Blood-Pressure Treatment & Patient-Reported Outcomes: In the Systolic Blood Pressure Intervention Trial (SPRINT), patient-reported outcomes were similar when hypertension was managed using intensive- and standard-treatment approaches, researchers report, supporting use of the more effective intensive approach (pp. 733–44). A total of 9,361 participants were treated to blood-pressure targets of <120 or <140 mm Hg, with these patient-reported outcomes on the Physical Component Summary (PCS) and Mental Component Summary (MCS) of the Veterans RAND 12-Item Health Survey, the Patient Health Questionnaire 9-item depression scale (PHQ-9): “Participants who received intensive treatment received an average of one additional antihypertensive medication, and the systolic blood pressure was 14.8 mm Hg (95% confidence interval, 14.3 to 15.4) lower in the group that received intensive treatment than in the group that received standard treatment. Mean PCS, MCS, and PHQ-9 scores were relatively stable over a median of 3 years of follow-up, with no significant differences between the two treatment groups. No significant differences between the treatment groups were noted when participants were stratified according to baseline measures of physical or cognitive function. Satisfaction with blood-pressure care was high in both treatment groups, and we found no significant difference in adherence to blood-pressure medications.” (D. R. Berlowitz, dan.berlowitz@va.gov)
Cost-Effectiveness of Intensive Blood-Pressure Control: Benefits of intensive blood-pressure control as demonstrated in SPRINT were cost-effective when trial data were analyzed in a microsimulation model (pp. 745–55). Applying treatment effects and health care costs to a hypothetical cohort of adults, authors “determined that the mean number of [quality-adjusted life-years (QALYs)] would be 0.27 higher among patients who received intensive control than among those who received standard control and would cost approximately $47,000 more per QALY gained if there were a reduction in adherence and treatment effects after 5 years; the cost would be approximately $28,000 more per QALY gained if the treatment effects persisted for the remaining lifetime of the patient.” (A.

Marginal Costs of Inpatient Adverse Drug Events: The importance of accounting for confounders in analysis of anticoagulant and hypoglycemic adverse drug events (ADEs) is demonstrated in a study of the 2010 to 2013 Healthcare Cost and Utilization Project State Inpatient Databases and Medicare Patient Safety Monitoring System (pp. 856–63). Investigators estimated “the marginal cost (MC) of ADEs associated with anticoagulants and hypoglycemic agents for adults in 5 patient groups during their hospital stay and the total annual ADE costs for all patients exposed to these drugs during their stay, with these results: “Adjusted MC estimates were smaller than unadjusted measures with most groups showing estimates that were at least 50% less. Adjusted anticoagulant ADE costs added >45% and hypoglycemic ADE costs added >20% to inpatient costs. The 2013 hospital cost estimates for ADEs associated with anticoagulants and hypoglycemic agents were >$2.5 billion for each drug class.” (W. D. Spector, william.spector@ahrq.hhs.gov)
ACA Dependent Coverage Mandate & Dental Care: Extension of employee dental coverage to older dependents (up to 26 years of age) by the Affordable Care Act (ACA) had little effect on overall preventive dental service utilization, a study shows, but restorative care increased after implementation of the law, especially for women (pp. 841–7). Using difference-in-difference regression approach comparing changes in dental care utilization for 25-year olds affected by the policy to unaffected 27-year olds, the authors found these patterns: “Compared to 27-year olds, 25-year olds were 8 percentage points more likely to have private dental coverage in the 3 years following the mandate. We do not find compelling evidence that young adults increased their use of preventive dental services in response to gaining insurance. We do find a nearly 5 percentage point increase in the likelihood of dental treatments among 25-year olds following the mandate, an effect that appears concentrated among women.” (D. M.

Greater Health Gains With FDA-Expedited Drugs: Drug products expedited by FDA are resulting in greater health gains than medications approved through regular processes, according to an analysis of drugs approved in 1999–2012 through expedited (n = 26) or regular processes (n = 59) (pp. 1408–15): “We found that drugs in at least one expedited review program offered greater gains than drugs reviewed through conventional processes (0.182 versus 0.003 [quality-adjusted life–years, or QALYs]). We also found that, compared to drugs not included in the same program, greater gains were provided by drugs in the priority review (0.175 versus 0.007 QALYs), accelerated approval (0.370 versus 0.031 QALYs), and fast track (0.254 versus 0.014 QALYs) programs.

The annual National Immunization Survey–Teen report found that 60% of teens ages 13 to 17 received one or more doses of HPV vaccine in 2016, an increase of 4 percentage points from 2015. The report also showed that HPV vaccination is becoming more common among boys. About 65% of girls received the first dose of HPV vaccine compared to 56% of boys receiving the first dose. These latest estimates represent a 6 percentage point increase from 2015 for boys and about the same for girls.

De-escalation of Antiplatelet Treatment in ACS/PCI: “Early de-escalation of antiplatelet treatment can be considered as an alternative approach in patients with acute coronary syndrome managed with [percutaneous coronary intervention (PCI)],” conclude investigators in the TROPICAL-ACS trial, citing noninferior results when the intervention was compared with standard prasugrel therapy at 1 year (10.1016/S0140-6736(17)32155-4). Using as a primary endpoint of net clinical benefit (cardiovascular death, myocardial infarction, stroke or bleeding grade 2 or higher according to Bleeding Academic Research Consortium [BARC]) criteria) 1 year after randomization, the study showed these results for a step-down prasugrel regimen of 1 week prasugrel followed by 1 week clopidogrel and platelet function testing–guided maintenance therapy with clopidogrel or prasugrel from day 14 after hospital discharge: “Between Dec 2, 2013, and May 20, 2016, 2,610 patients were assigned to study groups; 1,304 to the guided de-escalation group and 1,306 to the control group. The primary endpoint occurred in 95 patients (7%) in the guided de-escalation group and in 118 patients (9%) in the control group (pnon-inferiority = 0.0004; hazard ratio [HR] 0.81 [95% CI 0.62–1.06], psuperiority = 0.12). Despite early de-escalation, there was no increase in the combined risk of cardiovascular death, myocardial infarction, or stroke in the de-escalation group (32 patients [3%]) versus in the control group (42 patients [3%]; pnon-inferiority = 0.0115). There were 64 BARC 2 or higher bleeding events (5%) in the de-escalation group versus 79 events (6%) in the control group (HR 0.82 [95% CI 0.59–1.13]; p = 0.23).” (D.

Procalcitonin-Guided Sepsis Treatment in Neonates: In neonates with suspected early-onset sepsis, procalcitonin-guided decisions were superior to standard care in reducing antibiotic therapy, researchers report (pp. 871–81): “Between May 21, 2009, and Feb 14, 2015, we screened 2,440 neonates with suspected early-onset sepsis. 622 infants were excluded due to lack of parental consent, 93 were ineligible for reasons unknown (68), congenital malformation (22), or surgery in the first week of life (3). 14 neonates were excluded as 100% data monitoring or retrieval was not feasible, and one neonate was excluded because their procalcitonin measurements could not be taken. 1,710 neonates were enrolled and randomly assigned to either procalcitonin-guided therapy (n = 866) or standard therapy (n = 844). 1,408 neonates underwent per-protocol analysis (745 in the procalcitonin group and 663 standard group). For the procalcitonin group, the duration of antibiotic therapy was reduced (intention to treat: 55.1 vs 65.0 h, p <0.0001; per protocol: 51.8 vs 64.0 h; p <0.0001). No sepsis-related deaths occurred, and 9 (<1%) of 1,710 neonates had possible re-infection. The risk difference for non-inferiority was 0.1% (95% CI −4.6 to 4.8) in the intention-to-treat analysis (5 [0.6%] of 866 neonates in the procalcitonin group vs 4 [0.5%] of 844 neonates in the standard group) and 0.1% (−5.2 to 5.3) in the per-protocol analysis (5 [0.7%] of 745 neonates in the procalcitonin group vs 4 [0.6%] of 663 neonates in the standard group).” (W. van Herk, w.vanherk@erasmusmc.nl)

Community Pharmacist Training & CKD Care: In Quebec, pharmacists receiving training and patient-specific clinical summaries from hospital pharmacists provided better care to patients with chronic kidney disease (CKD), a study shows (pp. 386–96). Community pharmacies and their patients were randomized to ProFiL, a training-and-communication network program, or a control group, and performance was assessed based on a primary outcome of drug-related problems and other variables. Concluding that “providing community pharmacists with essential clinical data, appropriate training, and support from hospital pharmacists with expertise in nephrology increases pharmacists’ knowledge and reduces drug-related problems in patients with CKD who are followed up in clinics incorporating a multidisciplinary health care team,” the authors report these results: “207 community pharmacies, 494 pharmacists, and 442 patients with CKD participated. After 1 year, the mean number of drug-related problems per patient decreased from 2.16 to 1.60 and from 1.70 to 1.62 in the ProFiL and control groups, respectively. The difference in reduction of drug-related problems per patient between the ProFiL and control groups was −0.32 (95% CI, −0.63 to −0.01). Improvements in knowledge (difference, 4.5%; 95% CI, 1.6%–7.4%) and clinical competencies (difference, 7.4%; 95% CI, 3.5%–11.3%) were observed among ProFiL pharmacists. No significant differences in clinical attributes were observed across the groups.” (L. Lalonde, lyne.lalonde@umontreal.ca)
Treating to Target in Older Hypertensive Patients: In a commentary that assesses for nephrologists a clinical practice guideline from the American College of Physicians and the American Academy of Family Physicians (see PNN, Mar. 21) (ACP/AAFP), an author concludes that “future studies are needed to determine the value of more versus less intensive treatment in [older adults with hypertension] more typical of [patients] seen daily in clinical practice who commonly have multiple comorbid conditions that have excluded their participation in trials to date” (pp. 311–4). “To help nephrologists, studies are needed to determine optimal [blood pressure (BP)] thresholds and targets in patients with advanced CKD and those receiving renal replacement therapies,” the author writes, adding these details, “I find the recommendations of the current ACP/AAFP guideline to be reasonable to guide decisions on BP thresholds and targets in older hypertensive patients. A very important statement in the ACP/AAFP guideline should be kept in mind when applying any guideline recommendation to clinical practice. ‘Clinical practice guidelines are ‘guides’ only and may not apply to all patients and all clinical situations. Thus, they are not intended to override a clinician’s judgment.’ Clinicians should use all available evidence and individual patient factors to decide on best treatment thresholds and goals using the principles of shared decision making. Many patients encountered in clinical practice do not meet entry criteria for the studies used to inform guidelines.” (G. L. Schwartz, gschwartz@mayo.edu)

Diabetes & Hypertension: Reductions in cardiovascular events among patients with diabetes can be attributed to better control of blood pressure, the American Diabetes Association concludes in an updated position statement (pp. 1273–84). “Hypertension is a strong risk factor for atherosclerotic cardiovascular disease (ASCVD), heart failure, and microvascular complications,” the statement notes. “ASCVD—defined as acute coronary syndrome, myocardial infarction (MI), angina, coronary or other arterial revascularization, stroke, transient ischemic attack, or peripheral arterial disease presumed to be of atherosclerotic origin—is the leading cause of morbidity and mortality for individuals with diabetes and is the largest contributor to the direct and indirect costs of diabetes. Numerous studies have shown that antihypertensive therapy reduces ASCVD events, heart failure, and microvascular complications in people with diabetes. Large benefits are seen when multiple risk factors are addressed simultaneously. There is evidence that ASCVD morbidity and mortality have decreased for people with diabetes since 1990 likely due in large part to improvements in blood pressure control.” (G. Bakris, gbakris@medicine.bsd.uchicago.edu)
Declines in Incidence of Diabetes: “It is premature to declare victory against the epidemic of diabetes in the U.S.,” authors conclude, suggesting instead a focus on “current public health efforts, including a specific emphasis to address prediabetes” (pp. 1139–43). Based on multiple sources of data on the incidence of diabetes, these patterns are evident: “National surveillance data show a sustained decline in the incidence rate of diagnosed diabetes, which has been heralded as a success in the battle against diabetes in the U.S.… Although some of the incidence decline may represent real progress against diabetes, it is likely that there are also nonbiological factors at play, especially changes in diagnostic criteria for diabetes. We present and discuss data that suggest improved detection and changes in screening and diagnostic practices may have resulted in the depletion of the ‘susceptible population.’” (E. Selvin, eselvin@jhu.edu)
“The most important statement from [this] article is ‘the war is not yet won,’” writes an editorialist (
pp. 1152–3). “There is no inherent reason to celebrate the decline in incidence seen in adults. It is a victory of sorts, but the number of people living with diabetes is staggering and increasing. An alarmingly high and increasing proportion of our nation’s health care resources are expended in the care of diabetes and its complications and comorbidities. The burden of diabetes care not only impacts the quality of life of hundreds of millions of people globally but also stresses our health care systems and as a result our society to near the breaking point. Recent trends examining the incidence of diabetes in youth in the U.S. demonstrated significant increases, particularly in racial and ethnic groups other than non-Hispanic whites. One can only imagine the impact this will have on our health care system.” (L. A. Young, laura_young@med.unc.edu)
Glycemic Control & Hepatitis C Virus Treatment: Successful treatment of hepatitis C virus with direct-acting antiviral agents is associated with improved glycemic control in patients with type 2 diabetes, a study shows (pp. 1173–80; G. N. Ioannou, georgei@medicine.washington.edu).

Emicizumab Prophylaxis in Hemophilia A with Inhibitors: The recombinant, humanized, bispecific monoclonal antibody emicizumab significantly lowered the rate of bleeding events among study patients with hemophilia A with inhibitors, compared with no prophylaxis (pp. 809–18). HAVEN-1 participants were age 12 years or older and had hemophilia A with factor VIII inhibitors. Based on a primary end point of difference in bleeding rates, results showed: “The annualized bleeding rate was 2.9 events (95% confidence interval [CI], 1.7 to 5.0) among participants who were randomly assigned to emicizumab prophylaxis (group A, 35 participants) versus 23.3 events (95% CI, 12.3 to 43.9) among those assigned to no prophylaxis (group B, 18 participants), representing a significant difference of 87% in favor of emicizumab prophylaxis (P <0.001).” (J. Oldenburg, johannes.oldenburg@ukbonn.de)
“The results of this phase 3 trial are extremely important for the hemophilia treatment community, which has battled the hemostatic calamity of factor VIII inhibitor formation with the same bypassing therapies for the past 30 years,” writes an editorialist (
pp. 884–5). “Although the preferred treatment of the infrequent events of breakthrough bleeding during the administration of emicizumab is not clear, it is obvious that repeated high doses of activated prothrombin complex concentrate should be avoided. Similarly, how emicizumab prophylaxis will be integrated with current schedules for the induction of immune tolerance to factor VIII remains to be evaluated.” (D. Lillicrap)
Liraglutide and Renal Outcomes in Type 2 Diabetes: In the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) trial, liraglutide lowered rates of development and progression of diabetic kidney disease among 9,340 participants with type 2 diabetes and high cardiovascular risk, compared with placebo, researchers report (pp. 839–48). The current article includes results of prespecified secondary renal outcomes, including a composite of new-onset persistent macroalbuminuria, persistent doubling of the serum creatinine level, end-stage renal disease, or death due to renal disease. Investigators found these outcomes: “The renal outcome occurred in fewer participants in the liraglutide group than in the placebo group (268 of 4,668 patients vs. 337 of 4,672; hazard ratio, 0.78; 95% confidence interval [CI], 0.67 to 0.92; P = 0.003). This result was driven primarily by the new onset of persistent macroalbuminuria, which occurred in fewer participants in the liraglutide group than in the placebo group (161 vs. 215 patients; hazard ratio, 0.74; 95% CI, 0.60 to 0.91; P = 0.004). The rates of renal adverse events were similar in the liraglutide group and the placebo group (15.1 events and 16.5 events per 1,000 patient–years), including the rate of acute kidney injury (7.1 and 6.2 events per 1,000 patient–years, respectively).” (J.

Adverse Event Recurrence Following Immunization: Reimmunization of patients who had an adverse event following immunization (AEFI) is not studied well, conclude authors of a systematic review (10.1542/peds.2016-3707). “Published studies suggest that reimmunization is usually safe,” the group concludes. “However in these studies, severe cases were often not reimmunized.” Assessment of 29 articles published in English or French produced these findings: “Among patients with a history of hypotonic hyporesponsive episode (n = 398), anaphylaxis (n = 133), or seizures (n = 60) who were reimmunized, events recurred in 0% to 0.8%. Allergic-like events recurred in 30 of 594 reimmunized patients. Fever recurred in 0% to 84% of 836 reimmunized patients, depending on the vaccine and dose number. Among children with extensive limb swelling after the fourth dose of diphtheria–tetanus–acellular pertussis vaccine, recurrence was higher when the fifth dose was given with the full-antigen formulation (78%) compared with the reduced-antigen formulation (53%, P = .02).” (G. De Serres, gaston.deserres@inspq.qc.ca)
“This article … reinforces what vaccinologists and pediatricians have known for many years: vaccines are incredibly safe,” editorialists write (
10.1542/peds.2017-1760). “Considering that the vaccines in the infant schedule are administered to millions of children each year, the list of known adverse events, even rare ones, is impressively short. Although this article does not address the recurrence risk for all known AEFIs, particularly rare ones such as immune thrombocytopenic purpura after measles-containing vaccines and intussusception after rotavirus vaccine, it is impressively comprehensive and will be a useful reference for practicing pediatricians everywhere for years to come. This article will also help to reaffirm the overwhelming value and safety of vaccines in protecting infants and children from complications and death due to infectious diseases.” (S. T.

Antipsychotic Drug Trials in Acute Schizophrenia: During 60 years of placebo-controlled trials of antipsychotic agents in patients with acute schizophrenia, “approximately twice as many patients improved with antipsychotics as with placebo, but only a minority experienced a good response,” according to a systematic review, Bayesian meta-analysis, and meta-regression of efficacy predictors (10.1176/appi.ajp.2017.16121358): “The analysis included 167 double-blind randomized controlled trials with 28,102 mainly chronic participants. The standardized mean difference (SMD) for overall efficacy was 0.47 (95% credible interval 0.42, 0.51), but accounting for small-trial effects and publication bias reduced the SMD to 0.38. At least a ‘minimal’ response occurred in 51% of the antipsychotic group versus 30% in the placebo group, and 23% versus 14% had a ‘good’ response. Positive symptoms (SMD 0.45) improved more than negative symptoms (SMD 0.35) and depression (SMD 0.27). Quality of life (SMD 0.35) and functioning (SMD 0.34) improved even in the short term. Antipsychotics differed substantially in side effects. Of the response predictors analyzed, 16 trial characteristics changed over the decades. However, in a multivariable meta-regression, only industry sponsorship and increasing placebo response were significant moderators of effect sizes. Drug response remained stable over time.” (S.

Prescription Opioid Use & Use Disorders: The National Survey on Drug Use and Health (NSDUH) shows that one third of Americans used opioids during 2015, suggesting “a need to improve access to evidence-based pain management and to decrease excessive prescribing that may leave unused opioids available for potential misuse” (pp. 293–301). The survey of 51,200 civilian, noninstitutionalized adults showed these patterns of prescription opioid use, misuse, and use disorders: “Weighted NSDUH estimates suggested that, in 2015, 91.8 million (37.8%) U.S. civilian, noninstitutionalized adults used prescription opioids; 11.5 million (4.7%) misused them; and 1.9 million (0.8%) had a use disorder. Among adults with prescription opioid use, 12.5% reported misuse; of these, 16.7% reported a prescription opioid use disorder. The most commonly reported motivation for misuse was to relieve physical pain (63.4%). Misuse and use disorders were most commonly reported in adults who were uninsured, were unemployed, had low income, or had behavioral health problems. Among adults with misuse, 59.9% reported using opioids without a prescription, and 40.8% obtained prescription opioids for free from friends or relatives for their most recent episode of misuse.” (W.

Response rates were consistent across the 3 provider types: NPs, 89.3% (CI, 83.3% to 93.8%); PCPs, 86.9% (CI, 80.6% to 91.7%); and specialists, 83.8% (CI, 79.0% to 87.8%).

Nonspecific Vaccine Effects: Seeking to explain lower rates of hospitalization following measles and diphtheria, pertussis, and tetanus (DTP) vaccinations, researchers find that such nonspecific effects can occur with other vaccines and may be the result of healthy vaccinee bias (j3862). Compared with diphtheria, tetanus, pertussis, polio, and Haemophilus influenzae type b (DTaP-IPV-Hib)+pneumococcal vaccination (PCV) in the high-income country of the Netherlands, MMR at 2, 3, 4, and 11 months and MMR plus meningococcal C (MenC) vaccination at 14 months showed these associations with hospital admissions: “Having had MMR+MenC as the most recent vaccination was associated with a hazard ratio of 0.62 (95% confidence interval 0.57 to 0.67) for admission to hospital for infection and 0.84 (0.73 to 0.96) for injuries or poisoning, compared with the fourth DTaP-IPV-Hib+PCV as most recent vaccination. The fourth DTaP-IPV-Hib+PCV as most recent vaccination was associated with a hazard ratio of 0.69 (0.63 to 0.76) for admission to hospital for infection, compared with the third DTaP-IPV-Hib+PCV as most recent vaccination.” (M.

Immunization Exemptions in California: Medical exemptions (MEs) from compliance with California immunization requirements for schoolchildren increased in the first year under a law banning personal belief exemptions (PBEs), researchers report (pp. 863–4). “The statewide increase in the number of children with MEs in 2016 and the county-level correlation with past PBE use suggest that some vaccine-hesitant parents may have successfully located physicians willing to exercise the broader discretion provided by SB 277 for granting MEs,” the authors write. While the percentage of kindergarteners with MEs had been “largely stable” in the 20 years before passage of the law (SB 277), “the ME percentage increased from 0.17% to 0.51%. The PBE percentage decreased from 2.37% in 2015 to 0.56% in 2016, as PBEs for children who entered multiyear transitional kindergarten programs prior to 2016 remained valid. The total exemption percentage (PBEs + MEs) decreased from 2.54% in 2015 to 1.06% in 2016.” The investigators note that MEs rose in areas where PBEs had previously been high, creating a situation in which “portions of California may remain susceptible to vaccine-preventable disease outbreaks in the near future.” (P. L. Delamater, pld@email.unc.edu)
Personalized Management of Parkinson Disease: “The 2017 approach to the treatment of patients with [Parkinson disease (PD)] requires personalization of therapy and attention to the varied and changing symptoms,” conclude authors of a Viewpoint article (pp. 791–2). “Clinicians must be adept at diagnosing clusters of motor and nonmotor symptoms and mapping a comprehensive symptom-specific strategy that may necessitate involvement of a multidisciplinary team, including neurology, neuropsychology, psychiatry, neurosurgery, and rehabilitative services. Clinicians must also be aware that PD is dynamic and treatment strategies may need to shift abruptly as the disease progresses and the symptom clusters shift. The combination of medical therapy with exercise and in some cases surgical interventions can improve quality of life for most patients with PD and can transform a potentially debilitating disease into a livable condition.” (M. S. Okun, okun@neurology.ufl.edu)
Off-label Ketamine for Mood Disorders: Use of subanesthetic doses of ketamine for treating patients with mood disorders has generated enthusiasm among clinicians and patients whose depression has been refractory to standard therapies, according to a Viewpoint article (pp. 793–4). “However, considering the tremendous individual and societal burden of mood disorders, the high percentage of patients that do not achieve satisfactory responses from the currently available approved treatments, and the recent evidence of rising rates of suicide, expedited research into this potentially transformative treatment is needed,” the authors conclude. “Several ongoing studies (such as NCT01945047, NCT03113968, and NCT00088699) are attempting to address these knowledge gaps and enrollment in these trials should be encouraged when possible. In addition to the standard randomized clinical trials, the creation of a registry of patients receiving ketamine off-label as a treatment for mood disorders could serve as an efficient way to learn more about the longer-term effectiveness and safety of the treatment and could be beneficial in guiding the rational use of the treatment.” (G.

Third MMR Dose During Mumps Outbreaks: For managing mumps outbreaks in young adults, a third dose of measles–mumps–rubella (MMR) vaccine reverses waning immunity and improves disease control, researchers report (pp. 947–56). At the U. Iowa in 2015–16, investigators found these vaccine histories and immunity rates among 20,496 students, including 259 with mumps: “Before the outbreak, 98.1% of the students had received at least two doses of MMR vaccine. During the outbreak, 4,783 received a third dose. The attack rate was lower among the students who had received three doses than among those who had received two doses (6.7 vs. 14.5 cases per 1,000 population, P <0.001). Students had more than nine times the risk of mumps if they had received the second MMR dose 13 years or more before the outbreak. At 28 days after vaccination, receipt of the third vaccine dose was associated with a 78.1% lower risk of mumps than receipt of a second dose (adjusted hazard ratio, 0.22; 95% confidence interval, 0.12 to 0.39).

Based on a primary end point of forced expiratory volume in 1 second (FEV1) before bronchodilator use, once-daily inhaled tiotropium 18 mcg produced these results: “The FEV1 in patients who received tiotropium was higher than in those who received placebo throughout the trial (ranges of mean differences, 127 to 169 ml before bronchodilator use and 71 to 133 ml after bronchodilator use; P <0.001 for all comparisons). There was no significant amelioration of the mean (± SE) annual decline in the FEV1 before bronchodilator use: the decline was 38 ± 6 ml per year in the tiotropium group and 53 ± 6 ml per year in the placebo group (difference, 15 ml per year; 95% confidence interval [CI], −1 to 31; P = 0.06). In contrast, the annual decline in the FEV1 after bronchodilator use was significantly less in the tiotropium group than in the placebo group (29 ± 5 ml per year vs. 51 ± 6 ml per year; difference, 22 ml per year [95% CI, 6 to 37]; P = 0.006). The incidence of adverse events was generally similar in the two groups.” (P. Ran, pxran@gzhmu.edu.cn)
Editorialists speculate about the impact of more research into management of early COPD, which has historically not been treated (
pp. 988–9): “With the development of new drugs, would treatment with another drug in the class of long-acting muscarinic antagonists (LAMAs) or long-acting beta-agonists (LABAs) or a combination of LAMAs and LABAs help to improve lung function, slow the decline in lung function, improve quality of life, and decrease the incidence of exacerbations among patients with early COPD? Early intervention and treatment for patients with diabetes mellitus and hypertension certainly lead to better outcomes. Is such an early treatment strategy possible and effective for patients with mild COPD? Further studies of the newer drugs and longer-term studies are needed to improve available treatments for millions of patients with early-stage COPD worldwide. For now, the evidence supports the judicious use of treatment in patients with symptomatic early-stage COPD or in those who are recovering from an exacerbation.” (F. W. S. Ko)
Tezepelumab in Uncontrolled Asthma: In a phase 2 trial of 291 patients with asthma uncontrolled by long-acting beta-agonists and medium-to-high doses of inhaled glucocorticoids, tezepelumab reduced rates of clinically significant asthma exacerbations, compared with placebo (pp. 936–46). The agent is a human monoclonal antibody specific for the epithelial-cell–derived cytokine thymic stromal lymphopoietin. (J. Corren, jcorren@ucla.edu)

IVIg for Heparin-Induced Thrombocytopenia: Intravenous immunoglobulin (IVIg) treatment should be considered for patients with severe refractory heparin-induced thrombocytopenia (HIT), according to authors who described three cases and evaluated the mechanism of action in those patients and five others with severe HIT (pp. 478–85). Effects of a common polymorphism, H/R 131, in the platelet IgG receptor Fc-gamma-RIIa on IVIg-mediated inhibition of platelet activation, was also examined, with these results: “At levels attained in vivo, IVIg inhibits HIT antibody-mediated platelet activation. The constant domain of IgG (Fc) but not the antigen-binding portion (Fab) is required for this effect. Consistent with this finding, IVIg had no effect on HIT antibody binding in a solid-phase HIT immunoassay (platelet factor 4 enzyme-linked immunoassay). The H/R131 polymorphism in Fc-gamma-RIIa influences the susceptibility of platelets to IVIg treatment, with the HH131 genotype being most susceptible to IVIg-mediated inhibition of antibody-induced activation. However, at high doses of IVIg, activation of platelets of all Fc-gamma-RIIa genotypes was significantly inhibited. All three patients did well on long-term anticoagulation therapy with direct oral anticoagulants.” (A. Padmanabhan, anand.padmanabhan@bcw.edu)
“Although the concept of using IVIg for treating HIT has existed since at least 1994, it is a largely ignored treatment,” editorialists write (
pp. 453–5). “Moreover, a consensus conference guideline actually recommended against IVIg for treating HIT. However, the more recent observations describing IVIg as efficacious for HIT represent ‘rediscovery’ of an old therapy. Now, with the correlating clinical laboratory studies of Padmanabhan et al., together with the emerging concept of autoimmune HIT, it seems more likely that IVIg will become an important option for treating patients who have severe HIT.” (T. E. Warkentin, twarken@mcmaster.ca)
Statins in COPD: Administrative data from British Columbia suggest a role for statins in reducing lung-related and all-cause mortality in patients with chronic obstructive pulmonary disease (COPD), researchers report (pp. 486–93). Statin drug exposure in the year after COPD diagnosis was associated with these primary and secondary outcomes: “There were 39,678 patients with COPD that met the study inclusion criteria. Of them, 7,775 (19.6%) had received at least one statin drug dispensed in the exposure ascertainment window. There were 1,446 all-cause deaths recorded in the cohort in the 1-year period after exposure ascertainment. In multivariate analysis, the estimated hazard ratio (HR) for statin drug exposure was 0.79 (95% CI, 0.68–0.92; P = .0016), suggesting a 21% reduction in the risk from statin drug use on all-cause mortality. For lung-related mortality, there was also a considerable reduction in the risk for all-cause mortality from statin drug use (HR, 0.55; 95% CI, 0.32–0.93; P = .0254).” (L. D. Lynd, llynd@ubc.ca)
Vitamin D in Pediatric Asthma: Short- but not long-term reductions in asthma exacerbations were associated with rapid reversal of vitamin D deficiency in pediatric patients presenting in emergency departments with moderate-to-severe asthma exacerbations and vitamin D levels of 25 ng/mL or lower (pp. 527–36): “One hundred and sixteen patients in the IM + oral cohort vs 115 in the oral-only cohort had similar mean (SD) baseline levels: 15.1 (5.4) vs 15.8 (5.2) ng/mL (range, 3–25 ng/mL). There was no difference in the primary outcome [of patient-initiated unplanned visits for asthma exacerbations] over the entire 12-month observation period. However, rapid IM + oral supplementation significantly reduced unplanned visits for asthma exacerbations for children with baseline levels of 3 to 11 ng/mL during the initial 3 months: the relative exacerbation rate for the IM + oral cohort compared with the oral-only cohort at 3 months was 0.48 (95% CI, 0.28–0.89; P = .008); average exacerbation frequency per child analysis, relative rate 0.36 (95% CI, 0.13–0.87; P = .017). Otherwise, there were no significant differences between groups.” (B. L. Davidson, brucedavidson@pobox.com)

Safety Label Changes for Expedited Drugs: Medications approved by FDA under expedited pathways later need more and more serious safety labeling changes than other drugs, a study shows (j3837). Retrospective cohort analysis of public records for drugs approved in 1997–2016 showed the following: “Among the 382 eligible new drugs, 135 (35%) were associated with an expedited development or review pathway, and matches were available for 96 (71%). The matched pairs were associated with a total of 1,710 safety related label changes during the study period. Expedited pathway drugs were characterized by a rate of 0.94 safety related label changes for each drug per year, compared with 0.68 safety related label changes per year for non-expedited pathway drugs (rate ratio 1.38, 95% confidence interval 1.25 to 1.52). Compared with non-expedited pathway drugs, expedited pathway drugs had a 48% higher rate of changes to boxed warnings and contraindications, the two most clinically important categories of safety warnings (1.48, 95% confidence interval 1.07 to 2.06). A qualitative review of changes to the boxed warning sections revealed that less than 5% (3/67) were changed to describe reduced risks for patients.” (A. S. Kesselheim, akesselheim@bwh.harvard.edu)
Psychiatric Disorders & Antidepressant Use During Pregnancy: Exposure to antidepressants in utero is associated with increased risk of psychiatric disorders, according to data from the Danish national registry (j3668). Concluding that “focusing solely on a single psychiatric disorder among offspring in studies of in utero antidepressant exposure may be too restrictive,” the investigators report these findings for 905,383 liveborn singletons in 1998–2012 who were followed for up to 16.5 years: “Overall, psychiatric disorders were diagnosed in 32,400 children. The adjusted 15 year cumulative incidence of psychiatric disorders was 8.0% (95% confidence interval 7.9% to 8.2%) in the unexposed group, 11.5% (10.3% to 12.9%) in the antidepressant discontinuation group, 13.6% (11.3% to 16.3%) in the continuation group, and 14.5% (10.5% to 19.8%) in the new user group. The antidepressant continuation group had an increased risk of psychiatric disorders (hazard ratio 1.27, 1.17 to 1.38), compared with the discontinuation group.” (X. Liu, lxq@econ.au.dk)
Dental Procedures, Antibiotic Prophylaxis & Endocarditis: In adults with prosthetic heart valves, invasive dental procedures are associated with a small proportion of cases of infective endocarditis, a study shows, but the role of antibiotic prophylaxis requires further study (j3776). A nationwide, population-based cohort and a case–crossover study from France shows these relationships among dental procedures, antibiotic prophylaxis, and endocarditis: “The cohort included 138,876 adults with prosthetic heart valves (285,034 person years); 69,303 (49.9%) underwent at least one dental procedure. Among the 396,615 dental procedures performed, 103,463 (26.0%) were invasive and therefore presented an indication for antibiotic prophylaxis, which was performed in 52,280 (50.1%). With a median follow-up of 1.7 years, 267 people developed infective endocarditis associated with oral streptococci (incidence rate 93.7 per 100,000 person years, 95% confidence interval 82.4 to 104.9). Compared with non-exposure periods, no statistically significant increased rate of oral streptococcal infective endocarditis was observed during the three months after an invasive dental procedure (relative rate 1.25, 95% confidence interval 0.82 to 1.82; P = 0.26) and after an invasive dental procedure without antibiotic prophylaxis (1.57, 0.90 to 2.53; P = 0.08). In the case crossover analysis, exposure to invasive dental procedures was more frequent during case periods than during matched control periods (5.1% v 3.2%; odds ratio 1.66, 95% confidence interval 1.05 to 2.63; P = 0.03).” (S.

Antibiotic-Associated Adverse Events in Inpatients: As many as 20% of patients placed on antibiotic therapy while in the hospital have associated adverse effects, a study shows, including serious abnormalities of the gastrointestinal, renal, and hematologic systems (pp. 1308–15). Among 1,488 adults on general medicine wards at an academic medical center, these antibiotic-associated adverse drug events (ADEs) were identified within 30 days of treatment initiation: “The median age was 59 years (interquartile range, 49–69 years), and 758 (51%) participants were female. A total of 298 (20%) patients experienced at least 1 antibiotic-associated ADE. Furthermore, 56 (20%) non–clinically indicated antibiotic regimens were associated with an ADE, including 7 cases of Clostridium difficile infection. Every additional 10 days of antibiotic therapy conferred a 3% increased risk of an ADE. The most common ADEs were gastrointestinal, renal, and hematologic abnormalities, accounting for 78 (42%), 45 (24%), and 28 (15%) 30-day ADEs, respectively. Notable differences were identified between the incidence of ADEs associated with specific antibiotics.” (P. D. Tamma, ptamma1@jhmi.edu)
Long-term Opioid Therapy Guidelines in Primary Care: Use of a multicomponent intervention improved opioid treatment of patients on long-term analgesia, but the frequency of early-refill requests was unchanged, researchers report (pp. 1265–72). Cluster randomization of 53 primary care clinicians (PCCs) produced these outcomes when an intervention of nurse care management, an electronic registry, 1-on-1 academic detailing, and electronic decision tools for safe opioid prescribing was compared with a control consisting of only the decision tools: “Of the 985 participating patients, 519 were men, and 466 were women (mean [SD] patient age, 54.7 [11.5] years). Patients received a mean (SD) [morphine-equivalent daily dose (MEDD)] of 57.8 (78.5) mg. At 1 year, intervention patients were more likely than controls to receive guideline-concordant care (65.9% vs 37.8%; P <.001; adjusted odds ratio [AOR], 6.0; 95% CI, 3.6–10.2), to have a patient–PCC agreement (of the 376 without an agreement at baseline, 53.8% vs 6.0%; P <.001; AOR, 11.9; 95% CI, 4.4–32.2), and to undergo at least 1 [urine drug test] (74.6% vs 57.9%; P <.001; AOR, 3.0; 95% CI, 1.8–5.0). There was no difference in odds of early refill receipt between groups (20.7% vs 20.1%; AOR, 1.1; 95% CI, 0.7–1.8). Intervention patients were more likely than controls to have either a 10% dose reduction or opioid treatment discontinuation (AOR, 1.6; 95% CI, 1.3–2.1; P <.001). In adjusted analyses, intervention patients had a mean (SE) MEDD 6.8 (1.6) mg lower than controls (P <.001).” (J. M. Liebschutz, jane.liebschutz@bmc.org)
“Reversing the growth in opioid use for chronic pain is difficult because of the paucity of effective alternative treatments,” editorialists write (
p. 1272). “In the meantime, this study demonstrates that it is possible to increase safe prescribing habits among primary care physicians. We are encouraged by the increasing evidence of benefit of many nonnarcotic and nonpharmacologic approaches to chronic pain, such as mindfulness training or cognitive behavioral therapy, that appear as effective as opioids without the addiction and overdose risks. We hope to see more interventions focused on decreasing the use and harms of opioids among patients with chronic pain.” (S. R. Bauer, Scott.Bauer@ucsf.edu)

While emergency departments are preparing “for an influx of … visits from people suffering falls, cuts and other mishaps related to the recovery,” many of the 30 hospitals, 61 nursing homes, and 280 assisted-living facilities that closed over the weekend are dealing with a lack of power and in the Keys, no water or sewer service. Moving through Georgia as a tropical storm, Irma produced flooding in Savannah, downed trees and cut off power across much of the state, and changed wind patterns at the Atlanta Airport, forcing cancellation of hundreds of flights and affecting travel plans for many of the quarter million people who go through the facility on an average day.

Menopausal Hormone Therapy & Mortality: During a cumulative 18-year follow-up of the Women’s Health Initiative Estrogen Plus Progestin and Estrogen-Alone Trials, hormone therapy was not associated with increased risk of all-cause, cardiovascular, or cancer mortality, researchers report (pp. 927–38). Conjugated equine estrogens (CEE, 0.625 mg/d) plus medroxyprogesterone acetate (MPA, 2.5 mg/d) had these effects in comparison with placebo: “Among 27,347 women who were randomized (baseline mean [SD] age, 63.4 [7.2] years; 80.6% white), mortality follow-up was available for more than 98%. During the cumulative 18-year follow-up, 7,489 deaths occurred (1,088 deaths during the intervention phase and 6,401 deaths during postintervention follow-up). All-cause mortality was 27.1% in the hormone therapy group vs 27.6% in the placebo group (hazard ratio [HR], 0.99 [95% CI, 0.94–1.03]) in the overall pooled cohort; with CEE plus MPA, the HR was 1.02 (95% CI, 0.96–1.08); and with CEE alone, the HR was 0.94 (95% CI, 0.88–1.01). In the pooled cohort for cardiovascular mortality, the HR was 1.00 (95% CI, 0.92–1.08 [8.9 % with hormone therapy vs 9.0% with placebo]); for total cancer mortality, the HR was 1.03 (95% CI, 0.95–1.12 [8.2 % with hormone therapy vs 8.0% with placebo]); and for other causes, the HR was 0.95 (95% CI, 0.88–1.02 [10.0% with hormone therapy vs 10.7% with placebo]), and results did not differ significantly between trials. When examined by 10-year age groups comparing younger women (aged 50–59 years) to older women (aged 70–79 years) in the pooled cohort, the ratio of nominal HRs for all-cause mortality was 0.61 (95% CI, 0.43–0.87) during the intervention phase and the ratio was 0.87 (95% CI, 0.76–1.00) during cumulative 18-year follow-up, without significant heterogeneity between trials.” (J. E. Manson, jmanson@rics.bwh.harvard.edu)
“This information will be helpful in counseling women considering whether to start hormone therapy and hopefully will alleviate concerns that many patients and physicians have about the initiation of hormone therapy,” editorialists write (
pp. 911–3). “For women with troubling vasomotor symptoms, premature menopause, or early-onset osteoporosis, hormone therapy appears to be both safe and efficacious. The data presented by Manson et al fully support the newly released 2017 hormone therapy position statement of the North American Menopause Society and are a welcome addition to current knowledge regarding hormone therapy administration.” (M.

Genetic Variants Related to CETP Inhibitors & Statins: Reacting to a genetic variants trial of more than 100,000 participants showing that “the clinical benefit of lowering LDL-C levels may … depend on the corresponding reduction in apoB-containing lipoprotein particles” (pp. 947–56; B. A. Ference, bference@med.wayne.edu), editorialists explain, “Trapping of an apoB particle within the arterial wall is the fundamental step that initiates the atherosclerotic process” (pp. 915–7). “The evidence summarized indicates that this process may be more closely related to the number of circulating particles as estimated by apoB levels than to the mass of cholesterol within these particles estimated by LDL-C levels. The logical next step is to reframe the lipid hypothesis as the lipoprotein particle hypothesis.” (E. D. Peterson, eric.peterson@duke.edu)
Medication Reconciliation v. Medication Review: Obtaining the medication list “should result from a thorough medication review, founded in medication reconciliation,” write authors (pp. 965–6) in response to a previous publication (pp. 2057–8; A. J. Rose, arose@rand.org). “The medication review process encompasses the 6 levels of reconciliation and adds optimizing medication impact. The medication review process must include the complementary, primary, and essential step of medication reconciliation. Medication reconciliation is a foundation from which to examine the medical appropriateness and patient-centeredness needed to create the correct medication list.” (K. M.

Rapid Molecular Drug-Susceptibility Test for Tuberculosis: An investigational assay shows promise as a rapid point-of-care test for antibiotic susceptibility of Mycobacterium tuberculosis, researchers report (pp. 1043–54). The Xpert MTB/RIF assay and sputum culture was studied in adults in China and South Korea with symptoms of tuberculosis, with these results: “Among the 308 participants who were culture-positive for M. tuberculosis, when phenotypic drug-susceptibility testing was used as the reference standard, the sensitivities of the investigational assay for detecting resistance were 83.3% for isoniazid (95% confidence interval [CI], 77.1 to 88.5), 88.4% for ofloxacin (95% CI, 80.2 to 94.1), 87.6% for moxifloxacin at a critical concentration of 0.5 μg per milliliter (95% CI, 79.0 to 93.7), 96.2% for moxifloxacin at a critical concentration of 2.0 μg per milliliter (95% CI, 87.0 to 99.5), 71.4% for kanamycin (95% CI, 56.7 to 83.4), and 70.7% for amikacin (95% CI, 54.5 to 83.9). The specificity of the assay for the detection of phenotypic resistance was 94.3% or greater for all drugs except moxifloxacin at a critical concentration of 2.0 μg per milliliter (specificity, 84.0% [95% CI, 78.9 to 88.3]). When DNA sequencing was used as the reference standard, the sensitivities of the investigational assay for detecting mutations associated with resistance were 98.1% for isoniazid (95% CI, 94.4 to 99.6), 95.8% for fluoroquinolones (95% CI, 89.6 to 98.8), 92.7% for kanamycin (95% CI, 80.1 to 98.5), and 96.8% for amikacin (95% CI, 83.3 to 99.9), and the specificity for all drugs was 99.6% (95% CI, 97.9 to 100) or greater.” (S.

Sibling Vaccination Rates After a Child Develops Autism: As part of a study of “high risk” younger siblings of children with autism spectrum disorder, investigators show decreased vaccination rates with measles–mumps–rubella (MMR) vaccine among these children, compared with “low risk” siblings in unaffected families (pp. 1099–101). “Families with children who had autism spectrum disorder were less likely to vaccinate subsequent children,” authors of a letter report. “Specifically, the rate of vaccination among full biologic infant siblings of children with autism spectrum disorder was 83.1%, as compared with 97.0% among low-risk infants (Pearson chi-square value with one degree of freedom, 12.62; P <0.001). These findings are consistent with reported rates of MMR vaccination among children at older ages and across broader sampling regions.” (G. Glickman, glickman@ucsd.edu)
Patent Foramen Ovale Closure or Medical Management After Stroke: “How can we now have three trials showing that [patent foramen ovale (PFO)] closure prevents recurrent stroke, given that in the past 5 years, the Journal published articles from three other trials that showed the opposite?” asks an editorialist (pp. 1093–5; A. H. Ropper) Reports in the current issue show a lower rate of stroke recurrence among those assigned to PFO closure plus antiplatelet therapy, compared with antiplatelet therapy alone (pp. 1011–21; J-L Mas, jl.mas@ch-sainte-anne.fr); find a lower rate of recurrent ischemic strokes among adults with cryptogenic ischemic strokes managed with PFO closure plus medical therapy than with medical therapy alone (pp. 1022–32; J. L. Saver, jsaver@mednet.ucla.edu); demonstrate in a multinational trial fewer strokes with PFO closure/antiplatelet therapy than antiplatelet agents alone (pp. 1033–42; S. E.

Bacteriuria in VA Hospitals: The treatment of asymptomatic bacteriuria (ASB) with prolonged courses of antibiotics is quantified in a study of urinary tract infections (UTIs) among inpatients at Veterans Affairs hospitals (pp. 910–7). Manual chart review revealed these patterns of disease and treatment of inpatients with ASB or symptomatic UTIs: “Among 2,225 episodes of bacteriuria, 64% were classified as ASB. After excluding patients with non-UTI indications for antibiotics, 72% of patients with ASB received antibiotics. When evaluating only patients not meeting [Systemic Inflammatory Response Syndrome] criteria, 68% of patients with ASB received antibiotics. The mean (± SD) days of antibiotic therapy for ASB, cystitis, [catheter-associated]-UTI and pyelonephritis were 10.0 (4.5), 11.4 (4.7), 12.0 (6.1), and 13.6 (5.3), respectively. In sum, 14% of patients with ASB were treated for greater than 14 days, and fluoroquinolones were the most commonly used empiric antibiotic for ASB [245/691 (35%)]. Complications were rare but more common among patients with ASB treated with antibiotics.” (E. S. Spivak, emily.spivak@hsc.utah.edu)
Multidrug-Resistant Gonorrhea: A “cluster of genetically related gonococcal isolates with decreased ceftriaxone susceptibility and high-level azithromycin resistance may bring the threat of treatment failure in the United States with the current recommended dual therapy one step closer,” authors conclude based on a report of 7 patients in Hawaii (pp. 918–23). Over a period of less than 3 weeks in 2016, eight Neisseria gonorrhoeae isolates in these patients had elevated azithromycin minimum inhibitory concentrations (MICs) >256 mcg/mL and elevated ceftriaxone MICs (≥0.125 mcg/mL). Further study of the isolates and patient interviews showed the following: “All isolates had azithromycin MICs >16 µg/mL and 5 had ceftriaxone MICs = 0.125 µg/mL by agar dilution. All isolates were beta-lactamase positive and were resistant to penicillin, tetracycline, and ciprofloxacin. Genomic analysis revealed genetic relatedness. No patients reported recent travel or antibiotic use, and no male patients reported male sex partners. All patients were successfully treated.” (A. R. Katz, katz@hawaii.edu)

Arsenic & Anthracyclines in Acute Promyelocytic Leukemia: Arsenic trioxide (ATO) consolidation permitted significant reductions in cumulative anthracycline doses in pediatric patients with newly diagnosed acute promyelocytic leukemia (APL), Children’s Oncology Group AAML0631 investigators report (pp. 3021–9). With patients stratified as standard risk (SR) or high risk (HR) on the basis of diagnostic white blood cell count, the phase 3 trial shows: “One hundred one patients (66 SR and 35 HR) were evaluable for outcome. The 3-year overall survival was 94%, and event-free survival (EFS) was 91%. For SR and HR patients with APL, the overall survival was 98% versus 86% (P = .003), and EFS was 95% versus 83% (P = .03), respectively. The EFS for SR patients in AAML0631 was noninferior to that of patients in the AIDA 0493 historical control, which used a significantly higher anthracycline dose and did not include ATO consolidation. Relapse risk for patients in AAML0631 from end consolidation 1 (after ATO treatment) was only 4% at 3 years and did not differ significantly between SR and HR patients.” (M. A.

Global Burden of Disease Study 2016: In one of seven articles in this issue detailing results of the Global Burden of Disease Study 2016, authors examine worldwide mortality rates in young children and adults, age-specific mortality, and life expectancy, reaching this conclusion (pp. 1084–150): “Globally, mortality rates have decreased across all age groups over the past five decades, with the largest improvements occurring among children younger than 5 years. However, at the national level, considerable heterogeneity remains in terms of both level and rate of changes in age-specific mortality; increases in mortality for certain age groups occurred in some locations. We found evidence that the absolute gap between countries in age-specific death rates has declined, although the relative gap for some age-sex groups increased. Countries that now lead in terms of having higher observed life expectancy than that expected on the basis of development alone, or locations that have either increased this advantage or rapidly decreased the deficit from expected levels, could provide insight into the means to accelerate progress in nations where progress has stalled.” (C.

Anxiety Relapse After Antidepressant Discontinuation: Used in treatment of patients with diverse anxiety disorders, antidepressants continue to provide benefits when continued for up to 1 year, a study shows (j3927). Systematic review and meta-analyses of relapse prevention trials showed these results for patients with anxiety disorders, obsessive–compulsive disorder, or posttraumatic stress disorder: “The meta-analysis included 28 studies (n = 5,233) examining relapse with a maximum follow-up of one year. Across studies, risk of bias was considered low. Discontinuation increased the odds of relapse compared with continuing antidepressants (summary odds ratio 3.11, 95% confidence interval 2.48 to 3.89). Subgroup analyses and meta-regression analyses showed no statistical significance. Time to relapse (n = 3,002) was shorter when antidepressants were discontinued (summary hazard ratio 3.63, 2.58 to 5.10; n = 11 studies). Summary relapse prevalences were 36.4% (30.8% to 42.1%; n = 28 studies) for the placebo group and 16.4% (12.6% to 20.1%; n = 28 studies) for the antidepressant group, but prevalence varied considerably across studies, most likely owing to differences in the length of follow-up. Dropout was higher in the placebo group (summary odds ratio 1.31, 1.06 to 1.63; n = 27 studies).” (N. Batelaan, n.batelaan@ggzingeest.nl)
Glaucoma & Intraocular Pressure: As a measure for detecting glaucoma, intraocular pressure (IOP) “is inaccurate and probably not viable,” researchers conclude (j3889). In the EPIC-Norfolk Eye Study, 8,623 participants aged 48 to 92 years who underwent ocular examination to identify glaucoma had these outcomes: “The mean IOP in 8,401 participants was 16.3 mm Hg (95% confidence interval 16.2 mm Hg to 16.3 mm Hg; SD 3.6 mm Hg). In 363 participants (4%), glaucoma was present in either eye; 314 (87%) had primary open angle glaucoma. In the remaining participants, glaucoma was suspected in 607 (7%), and 863 (10.0%) had ocular hypertension. Two thirds (242) of those with glaucoma had previously already received the diagnosis. In 76% of patients with newly diagnosed primary open angle glaucoma (83/107), the mean IOP was under the threshold for ocular hypertension (21 mm Hg). No one IOP threshold provided adequately high sensitivity and specificity for diagnosis of glaucoma.” (P. Foster, p.foster@ucl.ac.uk)

Continuous Glucose Monitoring in Type 2 Diabetes: Patients on intensive glycemic therapy for type 2 diabetes more frequently use of continuous glucose monitoring (CGM), based on results of a study of adults conducted at 25 endocrinologic practices in North America (pp. 365–74). Among 158 patients randomized to CGM or usual care, these results were reported for glycemic control using multiple daily insulin injections over a 24-week period: “Mean HbA1c levels decreased to 7.7% in the CGM group and 8.0% in the control group at 24 weeks (adjusted difference in mean change, −0.3% [95% CI, −0.5% to 0.0%]; P = 0.022). The groups did not differ meaningfully in CGM-measured hypoglycemia or quality-of-life outcomes. The CGM group averaged 6.7 days (SD, 0.9) of CGM use per week.” (R. W. Beck, rbeck@jaeb.org)
Kidney, Cardiovascular Outcomes & Intensive SBP Control: While intensive control of systolic blood pressure (SBP) is connected to an increased risk of kidney disease, this is “outweighed by cardiovascular and all-cause mortality benefits,” SPRINT researchers report based on outcomes of 6,662 participants (pp. 375–83). A composite of all-cause death or cardiovascular event showed the following when analyzed along with changes in estimated glomerular filtration rates (eGFRs) and prespecified incident CKD: “The difference in adjusted mean eGFR between the intensive and standard groups was −3.32 mL/min/1.73 m2 (95% CI, −3.90 to −2.74 mL/min/1.73 m2) at 6 months, was −4.50 mL/min/1.73 m2 (CI, −5.16 to −3.85 mL/min/1.73 m2) at 18 months, and remained relatively stable thereafter. An incident CKD event occurred in 3.7% of participants in the intensive group and 1.0% in the standard group at 3-year follow-up, with a hazard ratio of 3.54 (CI, 2.50 to 5.02). The corresponding percentages for the composite of death or cardiovascular event were 4.9% and 7.1% at 3-year follow-up, with a hazard ratio of 0.71 (CI, 0.59 to 0.86).” (S.

Maraviroc-Containing Regimens for HIV Prophylaxis: For HIV preexposure prophylaxis (PrEP), the investigational drug maraviroc (MVC) was safe and well-tolerated compared with tenofovir disoproxil fumarate (TDF) plus emtricitabine (FTC) (pp. 384–93). A phase 2 trial produced these results among 188 participants who were not initially infected with HIV despite condomless vaginal or anal intercourse with at least one man with HIV infection or unknown serostatus within 90 days: “Grade 3 or 4 adverse events occurred in 5 (MVC), 13 (MVC–FTC), 9 (MVC–TDF), and 8 (TDF–FTC) participants; rates did not differ among regimens. One death (by suicide) occurred in the MVC–TDF group but was judged not to be related to study drugs. Of available plasma samples at week 48 (n = 126), 60% showed detectable drug concentrations. No new HIV infections occurred.” (R. M. Gulick, rgulick@med.cornell.edu)
ACP Reaffirms Opposition to Physician-Assisted Suicide: Citing ethical arguments and clinical, policy, legal, and other concerns, the American College of Physicians reaffirms its opposition to legalization of physician-assisted suicide in this issue of Annals, and also affirms a professional responsibility to improve the care of dying patients (10.7326/M17-0938). The update to a 2001 position paper discusses the role of palliative and hospice care, explores the nature of the patient–physician relationship and the critical distinction between refusal of life-sustaining treatment and physician-assisted suicide, and provides recommendations to physicians for responding to patient requests for physician-assisted suicide, recognizing that some individual cases will be medically and ethically challenging. The article notes that medical ethics and the law strongly support a patient’s right to refuse treatment, including life-sustaining treatment. The intent is to avoid or withdraw treatment judged by the patient as unduly burdensome and inconsistent with her health goals and preferences, ACP writes. Death follows naturally after the refusal due to underlying disease. Vigorous management of pain and symptoms such as nausea at the end of life is ethical and, indeed appropriate, even when the risk of shortening life is foreseeable, if the intent is to relieve those symptoms.

Adding Metronidazole to Post-Cesarean Prophylaxis in Obesity: Higher risks of surgical site infections (SSIs) in patients with obesity may necessitate addition of metronidazole to cephalosporin prophylaxis in women with higher body mass indices who have cesarean deliveries, researchers report (pp. 1026–34). Compared with placebo in women with prepregnancy body mass indices of 30 or more, metronidazole produced these outcomes in 2010–15 among women treated with I.V. cephalexin before surgery and oral cephalexin afterwards: “Among 403 randomized participants who were included (mean age, 28 [SD, 6] years; mean BMI, 39.7 [SD, 7.8]), 382 (94.6%) completed the trial. The overall rate of SSI was 10.9% (95% CI, 7.9%–14.0%). Surgical site infection was diagnosed in 13 women (6.4%) in the cephalexin–metronidazole group vs 31 women (15.4%) in the placebo group (difference, 9.0% [95% CI, 2.9%-15.0%]; relative risk, 0.41 [95% CI, 0.22–0.77]; P = .01). There were no serious adverse events, including allergic reaction, reported in either the antibiotic group or the placebo group.” (C. R. Warshak, eaglercr@ucmail.uc.edu)
“The results of this study suggest that a brief course of postoperative antimicrobial prophylaxis may significantly reduce the incidence of SSI among women with a prepregnancy body mass index of 30 or higher,” editorialists write (
pp. 1012–3). “Additional studies are needed to confirm these findings and to a determine if there are specific subpopulations within this group to whom the benefit is limited to avoid unnecessary antibiotic exposure and its associated risks among those unlikely to benefit. Furthermore, despite the apparent effectiveness of the intervention, the rate of SSI observed among women assigned to the postoperative antimicrobial prophylaxis group of the study was higher than that typically observed among nonobese women. This finding is important because it highlights that this strategy is not a panacea, that obese women remain at high risk of infectious complications, and that additional strategies to mitigate this risk are needed.” (D. P. Calfee, dpc9003@med.cornell.edu)
Managing Agitated Delirium During Palliative Care: In a preliminary study of 90 patients with advanced cancer who were hospitalized in an acute palliative care unit, addition of lorazepam to haloperidol resulted in better control of agitated delirium at 8 hours (pp. 1047–56). In 2014–16, lorazepam 3 mg I.V. or placebo produced these changes a primary outcome of change in Richmond Agitation-Sedation Scale (RASS) score in patients who also received haloperidol 2 mg I.V.: “Lorazepam + haloperidol resulted in a significantly greater reduction of RASS score at 8 hours (−4.1 points) than placebo + haloperidol (−2.3 points) (mean difference, −1.9 points [95% CI, −2.8 to −0.9]; P <.001). The lorazepam + haloperidol group required less median rescue neuroleptics (2.0 mg) than the placebo + haloperidol group (4.0 mg) (median difference, −1.0 mg [95% CI, −2.0 to 0]; P = .009) and was perceived to be more comfortable by both blinded caregivers and nurses (caregivers: 84% for the lorazepam + haloperidol group vs 37% for the placebo + haloperidol group; mean difference, 47% [95% CI, 14% to 73%], P = .007; nurses: 77% for the lorazepam + haloperidol group vs 30% for the placebo + haloperidol group; mean difference, 47% [95% CI, 17% to 71%], P = .005). No significant between-group differences were found in delirium-related distress and survival. The most common adverse effect was hypokinesia (3 patients in the lorazepam + haloperidol group [19%] and 4 patients in the placebo + haloperidol group [27%]).” (D. Hui, dhui@mdanderson.org)
“In this fast-paced world of medicine, the challenge for clinicians is to show patience and balance in seeking to reduce distressing symptoms, such as those involving severe pain or hyperactive delirium,” two editorialists conclude (
pp. 1014–5). “Ultimately, as the study by Hui et al sought to demonstrate, it is essential for clinicians to focus on the humanness of medicine; to keep dying patients comfortable and as awake as they and their families would like them to be so they can make the last few hours or days of life meaningful; and to make reasonable efforts not to cloud their sensorium unless essential to alleviate patient pain or other severe symptoms.” (P.

Canakinumab for Atherosclerotic Disease: Acting independently of lipid levels, the anti-inflammatory agent canakinumab lowered the rate of recurrent cardiovascular events among 10,061 patients with previous myocardial infarction and high C-reactive protein, according to the CANTOS trial (pp. 1119–31). A primary efficacy end point of nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death showed these outcomes with the interleukin-1-beta–targeting agent: “At 48 months, the median reduction from baseline in the high-sensitivity C-reactive protein level was 26 percentage points greater in the group that received the 50-mg dose of canakinumab, 37 percentage points greater in the 150-mg group, and 41 percentage points greater in the 300-mg group than in the placebo group. Canakinumab did not reduce lipid levels from baseline. At a median follow-up of 3.7 years, the incidence rate for the primary end point was 4.50 events per 100 person–years in the placebo group, 4.11 events per 100 person-years in the 50-mg group, 3.86 events per 100 person–years in the 150-mg group, and 3.90 events per 100 person–years in the 300-mg group. The hazard ratios as compared with placebo were as follows: in the 50-mg group, 0.93 (95% confidence interval [CI], 0.80 to 1.07; P = 0.30); in the 150-mg group, 0.85 (95% CI, 0.74 to 0.98; P = 0.021); and in the 300-mg group, 0.86 (95% CI, 0.75 to 0.99; P = 0.031). The 150-mg dose, but not the other doses, met the prespecified multiplicity-adjusted threshold for statistical significance for the primary end point and the secondary end point that additionally included hospitalization for unstable angina that led to urgent revascularization (hazard ratio vs. placebo, 0.83; 95% CI, 0.73 to 0.95; P = 0.005). Canakinumab was associated with a higher incidence of fatal infection than was placebo. There was no significant difference in all-cause mortality (hazard ratio for all canakinumab doses vs. placebo, 0.94; 95% CI, 0.83 to 1.06; P = 0.31).” (P. M. Ridker, pridker@partners.org)
“CANTOS has helped move the inflammatory hypothesis of coronary artery disease forward scientifically,” an editorialist writes (
pp. 1197–8). “However, the modest absolute clinical benefit of canakinumab cannot justify its routine use in patients with previous myocardial infarction until we understand more about the efficacy and safety trade-offs and unless a price restructuring and formal cost-effectiveness evaluation supports it.” (R. A. Harrington)
Anticoagulation in STEMI/NSTEMI: Bivalirudin and heparin produced similar outcomes among more than 6,000 patients undergoing percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) (pp. 1132–42): “At 180 days, a primary end-point event [death from any cause, myocardial infarction, or major bleeding during 180 days of follow-up] had occurred in 12.3% of the patients (369 of 3,004) in the bivalirudin group and in 12.8% (383 of 3,002) in the heparin group (hazard ratio, 0.96; 95% confidence interval [CI], 0.83 to 1.10; P = 0.54). The results were consistent between patients with STEMI and those with NSTEMI and across other major subgroups. Myocardial infarction occurred in 2.0% of the patients in the bivalirudin group and in 2.4% in the heparin group (hazard ratio, 0.84; 95% CI, 0.60 to 1.19; P = 0.33), major bleeding in 8.6% and 8.6%, respectively (hazard ratio, 1.00; 95% CI, 0.84 to 1.19; P = 0.98), definite stent thrombosis in 0.4% and 0.7%, respectively (hazard ratio, 0.54; 95% CI, 0.27 to 1.10; P = 0.09), and death in 2.9% and 2.8%, respectively (hazard ratio, 1.05; 95% CI, 0.78 to 1.41; P = 0.76).” (D. Erlinge, david.erlinge@med.lu.se)
“Even after VALIDATE-SWEDEHEART, there is no definitive answer to the question of whether to use bivalirudin or heparin during PCI,” concludes an editorialist (
pp. 1198–200). “Detailed data from ongoing studies of more than 36,000 patients randomly assigned to bivalirudin or heparin should provide robust evidence to guide decisions regarding anticoagulation among patients with STEMI and NSTEMI according to various patient characteristics, procedures, and adjunct pharmacotherapies.” (G. W. Stone)

PBMs & Opioids: Sharing some of the details behind yesterday’s announcement of restrictions on opioid dispensing, CVS Health staff described in a blog the company’s respective roles as a pharmacy benefits manager and prescription dispenser (9/21/17 blog): “In the face of the opioid crisis…, we believe it is time to give greater weight to the CDC Guideline — based on patient care and safety. The CDC Guideline should become the default approach to prescribing opiates, a scenario in which physicians would have to seek exceptions for those patients who need more medication or longer duration of therapy. What is more, pharmacy benefit managers are better placed than others in the pharmacy supply chain to put this approach to the CDC Guideline into practice. Wholesalers have no real contact with patients or payers. Retail pharmacists have opportunities to provide patient counseling about opiates, and are required by the Controlled Substance Act to exercise a ‘corresponding responsibility’ as to whether a prescription was issued for legitimate medical purpose. But when faced with a valid prescription written by a medical professional, it is difficult, and often not appropriate, for retail pharmacists to take it upon themselves to limit prescribing.” (T. Brennan)
Preferred SNF Networks: “Establishing preferred provider networks of skilled nursing facilities (SNFs) is one approach hospital administrators are using to reduce excess thirty-day readmissions and avoid Medicare penalties or to reduce beneficiaries’ costs as part of value-based payment models,” write researchers who found reduced readmission rates among such networks (pp. 1591–8). “However, hospitals are also required to provide patients at discharge with a list of Medicare-eligible providers and cannot explicitly restrict patient choice. This requirement complicates the development of a SNF network. Furthermore, there is little evidence about the effectiveness of network development in reducing readmission rates. We used a concurrent mixed-methods approach, combining Medicare claims data for the period 2009–13 with qualitative data gathered from interviews during site visits to hospitals in eight US markets in March–October 2015, to examine changes in rehospitalization rates and differences in practices between hospitals that did and did not develop formal SNF networks. Four hospitals had developed formal SNF networks as part of their care management efforts. These hospitals saw a relative reduction from 2009 to 2013 in readmission rates for patients discharged to SNFs that was 4.5 percentage points greater than the reduction for hospitals without formal networks. Interviews revealed that those with networks expanded existing relationships with SNFs, effectively managed patient data, and exercised a looser interpretation of patient choice.” (J. P.

Corticosteroids for Sore Throat: Pain associated with sore throat is relieved by single low doses of corticosteroids, conclude investigators who conducted a systematic review and meta-analysis of 10 trials of 1,426 patients (j3887): “Patients who received single low dose corticosteroids (the most common intervention was oral dexamethasone with a maximum dose of 10 mg) were twice as likely to experience pain relief after 24 hours (relative risk 2.2, 95% confidence interval 1.2 to 4.3; risk difference 12.4%; moderate quality evidence) and 1.5 times more likely to have no pain at 48 hours (1.5, 1.3 to 1.8; risk difference 18.3%; high quality). The mean time to onset of pain relief in patients treated with corticosteroids was 4.8 hours earlier (95% confidence interval −1.9 to −7.8; moderate quality) and the mean time to complete resolution of pain was 11.1 hours earlier (−0.4 to −21.8; low quality) than in those treated with placebo. The absolute pain reduction at 24 hours (visual analogue scale 0–10) was greater in patients treated with corticosteroids (mean difference 1.3, 95% confidence interval 0.7 to 1.9; moderate quality).” (B. Sadeghirad, sadeghb@mcmaster.ca)
Childhood IBD & Cancer Risk: Data from the Swedish national patient register for 1964–2014 indicate an association between childhood-onset inflammatory bowel disease (IBD) and increased risk of cancer, especially those involving the gastrointestinal tract, that has persisted over time (j3951). Children with ulcerative colitis, Crohn disease, or unclassified IBD had these cancer risk patterns: “During follow-up through adulthood (median age at end of follow-up 27 years), 497 (3.3 per 1,000 person years) people with childhood onset inflammatory bowel disease had first cancers, compared with 2,256 (1.5 per 1,000 person years) in the general population comparators (hazard ratio 2.2, 95% confidence interval 2.0 to 2.5). Hazard ratios for any cancer were 2.6 in ulcerative colitis (2.3 to 3.0) and 1.7 in Crohn’s disease (1.5 to 2.1). Patients also had an increased risk of cancer before their 18th birthday (2.7, 1.6 to 4.4; 20 cancers in 9,405 patients, 0.6 per 1,000 person years). Gastrointestinal cancers had the highest relative risks, with a hazard ratio of 18.0 (14.4 to 22.7) corresponding to 202 cancers in patients with inflammatory bowel disease.…” (O.

Long-Term Oral Bisphosphonate Therapy: Prolonged use of oral bisphosphonates among those in the Women’s Health Initiative adds to concerns about safety of the agents when taken for very long time periods (pp. 1924–31). The analysis includes 5,120 older women who reported at least 2 years of bisphosphonates in 2008–09. Annually determined outcomes were as follows during 3–5, 6–9, and 10–13 years of use: “On average participants were 80 years old and were followed for 3.7 ± 1.2 years. There were 127 hip, 159 wrist or forearm, 235 clinical vertebral, and 1,313 clinical fractures. In multivariate-adjusted analysis, 10 to 13 years of bisphosphonate use was associated with higher risk of any clinical fracture than 2 years of use (hazard ratio (HR) = 1.29, 95% confidence interval (CI) = 1.07–1.57). This association persisted in analyses limited to women with a prior fracture (HR = 1.30, 95% CI = 1.01–1.67) and women with no history of cancer (HR = 1.36, 95% CI = 1.10–1.68). The association of 10 to 13 years of use, compared with 2 years of use, was not statistically significant for hip (HR = 1.66, 95% CI = 0.81–3.40), clinical vertebral (HR = 1.65, 95% CI = 0.99–2.76), or wrist fracture (HR = 1.16, 95% CI = 0.67–2.00).” (R. L. Drieling, rdrieling@stanford.edu)
PPIs & Mild Cognitive Impairment and Dementia: Contrary to recent reports, an observational longitudinal study of Alzheimer disease (AD) centers found no relationship between self-reported PPI use and conversion to mild cognitive impairment, dementia, and specifically AD (pp. 1969–74; F. C. Goldstein, fgoldst@emory.edu).
Statin Use in Nursing Homes: In Ontario, statin prescribing was substantial for residents of nursing homes, including those who were frail, a study of 631 facilities shows (pp. 2044–51). Likelihood of statin prescribing varied substantially across physicians, the researchers add, noting these results for 2013–14: “Among 76,226 nursing home residents assigned to 1,919 physicians, 25,648 (33.6%) were statin users. There were 13,331 (30.1%) statin users among the 44,290 residents categorized as frail. In an adjusted mixed-effects logistic regression model, frail residents (adjusted odds ratio = 0.62, 95% confidence interval 0.58–0.65) were significantly less likely to be statin users compared with non-frail residents. After adjustment for resident characteristics, the intraclass correlation coefficient indicated that between-physician variability accounted for 9.1% of the residual unexplained variation in statin use (P < .001). Among the 894 physicians assigned 20 or more residents, funnel plots confirmed there were more low-outlying (17.4%) and high-outlying (12.0%) prescribers of statins than expected by chance. Physicians who were high-outlying prescribers had higher historical rates of statin prescribing.” (M. Campitelli, michael.campitelli@ices.on.ca)
Defining Delirium: At three Dutch medical centers, two experts evaluating a common set of data on 167 older adults varied widely on presence of delirium, researchers report (pp. 1932–8). Dutch Delirium Detection Study Group investigators found the following for 424 postoperative assessments performed by evaluators who viewed videos and reviewed clinical information: “The overall kappa was 0.61 (95% confidence interval = 0.53–0.68). There was no agreement between the experts for 89 (21.0%) assessments and a third delirium expert was needed for the final classification. Delirium screening that nurses performed detected 32% of the assessments that the experts diagnosed as (possibly) delirious.” (T. Numan, tiannenuman@gmail.com)

Genotype-Guided Warfarin Dosing: Tested in older adults undergoing hip or knee arthroplasty, genotype-guided warfarin dosing yielded significantly better clinical outcomes than clinically guided dosing, researchers report (pp. 1115–24). At six U.S. medical centers in the Genetic Informatics Trial (GIFT) of Warfarin to Prevent Deep Vein Thrombosis, patients genotyped for VKORC1-1639G>A, CYP2C9*2, CYP2C9*3, and CYP4F2 V433M polymorphisms had these responses to warfarin therapy based on a primary end point of composite of major bleeding, INR of 4 or greater, venous thromboembolism, or death: “Among 1,650 randomized patients (mean age, 72.1 years [SD, 5.4 years]; 63.6% women; 91.0% white), 1,597 (96.8%) received at least 1 dose of warfarin therapy and completed the trial (n = 808 in genotype-guided group vs n = 789 in clinically guided group). A total of 87 patients (10.8%) in the genotype-guided group vs 116 patients (14.7%) in the clinically guided warfarin dosing group met at least 1 of the end points (absolute difference, 3.9% [95% CI, 0.7%–7.2%], P = .02; relative rate [RR], 0.73 [95% CI, 0.56–0.95]). The numbers of individual events in the genotype-guided group vs the clinically guided group were 2 vs 8 for major bleeding (RR, 0.24; 95% CI, 0.05–1.15), 56 vs 77 for INR of 4 or greater (RR, 0.71; 95% CI, 0.51–0.99), 33 vs 38 for venous thromboembolism (RR, 0.85; 95% CI, 0.54–1.34), and there were no deaths.” (B. F. Gage, bgage@dom.wustl.edu)
“In addition to questions about the generalizability of the GIFT trial results, there are remaining questions about the cost-effectiveness of this strategy,” writes an editorialist (
pp. 1110–2). “Based on the GIFT trial composite primary outcome, 26 patients would need to be genotyped to prevent 1 ‘event’ (most commonly an INR ≥4). Although the cost of genotyping continues to decline, health insurers and publically funded health systems have not yet been convinced that genotype-guided warfarin prescribing is a cost-effective strategy worthy of investment. This is despite modeling from [European Pharmacogenetics of Anticoagulant Therapy] trial data suggesting that from a Swedish or UK health system perspective, pharmacogenomic testing would be cost-effective for patients with atrial fibrillation initiating warfarin therapy. Ideally an updated meta-analysis of trial data should be applied to cost-effectiveness modeling to inform new policy.” (J. D. Emery, jon.emery@unimelb.edu.au)
Biotin Interference With Assays: Ingestion of biotin 10 mg/d for 7 days was associated with interference on immunoassays in a preliminary study of 6 healthy adults (pp. 1150–60): “Among the 2 women and 4 men (mean age, 38 years [range, 31–45 years]) who took 10 mg/d of biotin for 7 days, biotin ingestion–associated interference was found in 9 of the 23 (39%) biotinylated assays compared with none of the 14 nonbiotinylated assays (P = .007). Results from 5 of 8 biotinylated (63%) competitive immunoassays tested falsely high and results from 4 out of 15 (27%) biotinylated sandwich immunoassays tested falsely low.” (D. Li, dannili@umn.edu)
Delirium in Older Persons: Drug treatment of delirium in older adults remains controversial, according to authors who reviewed research studies of 11,616 patients and other published systematic reviews, meta-analyses, and articles of other types (pp. 1161–74): “Advances in diagnosis have included the development of brief screening tools with high sensitivity and specificity, such as the 3-Minute Diagnostic Assessment; 4 A’s Test; and proxy-based measures such as the Family Confusion Assessment Method. Measures of severity, such as the Confusion Assessment Method–Severity Score, can aid in monitoring response to treatment, risk stratification, and assessing prognosis. Nonpharmacologic approaches focused on risk factors such as immobility, functional decline, visual or hearing impairment, dehydration, and sleep deprivation are effective for delirium prevention and also are recommended for delirium treatment. Current recommendations for pharmacologic treatment of delirium, based on recent reviews of the evidence, recommend reserving use of antipsychotics and other sedating medications for treatment of severe agitation that poses risk to patient or staff safety or threatens interruption of essential medical therapies.” (E.

Anacetrapib in Atherosclerotic Vascular Disease: Addition of the cholesteryl ester transfer protein (CETP) inhibitor anacetrapib to intensive statin therapy lowered the incidence of major cardiovascular events among patients with atherosclerotic vascular disease by a significant but small amount, according to the HPS3/TIMI55–REVEAL Collaborative Group (pp. 1217–27). Results in 30,449 adults based on a primary outcome of first major coronary event (composite of coronary death, myocardial infarction, or coronary revascularization) were as follows: “During the median follow-up period of 4.1 years, the primary outcome occurred in significantly fewer patients in the anacetrapib group than in the placebo group (1,640 of 15,225 patients [10.8%] vs. 1,803 of 15,224 patients [11.8%]; rate ratio, 0.91; 95% confidence interval, 0.85 to 0.97; P = 0.004). The relative difference in risk was similar across multiple prespecified subgroups. At the trial midpoint, the mean level of HDL cholesterol was higher by 43 mg per deciliter (1.12 mmol per liter) in the anacetrapib group than in the placebo group (a relative difference of 104%), and the mean level of non-HDL cholesterol was lower by 17 mg per deciliter (0.44 mmol per liter), a relative difference of −18%. There were no significant between-group differences in the risk of death, cancer, or other serious adverse events.” (M. J. Landray, reveal@ndph.ox.ac.uk)
“Will the REVEAL findings sufficiently motivate the sponsor to file for approval from the Food and Drug Administration?” asks an editorialist (
pp. 1284–5). “Relevant factors include the relatively small beneficial effect and the possible need for a replication study, especially given the track record of CETP inhibitors. The clinical relevance of subtle changes in the creatine kinase level and the glomerular filtration rate, plus the propensity of anacetrapib to linger in adipose tissue for years, also need to be clarified. Nonetheless, the fact that CETP inhibition remains in play reinforces Yogi Berra’s adage, ‘It ain’t over till it’s over.’” (R. A. Hegele)
Once-Weekly Exenatide & Cardiovascular Outcomes: In 14,752 patients with type 2 diabetes, the incidence of major adverse cardiovascular events was unchanged when once-weekly exenatide was added to usual care (pp. 1228–39): “A primary composite outcome event [first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke] occurred in 839 of 7,356 patients (11.4%; 3.7 events per 100 person–years) in the exenatide group and in 905 of 7,396 patients (12.2%; 4.0 events per 100 person–years) in the placebo group (hazard ratio, 0.91; 95% confidence interval [CI], 0.83 to 1.00), with the intention-to-treat analysis indicating that exenatide, administered once weekly, was noninferior to placebo with respect to safety (P <0.001 for noninferiority) but was not superior to placebo with respect to efficacy (P = 0.06 for superiority).…” (R. R. Holman, rury.holman@dtu.ox.ac.uk)
Rituximab in Mantle-Cell Lymphoma: In a phase 3 trial of 299 patients younger than 66 years who had mantle-cell lymphoma, use of rituximab maintenance therapy after autologous stem-cell transplantation significantly prolonged event-free survival, progression-free survival, and overall survival (pp. 1250–60): “Starting from randomization, the rate of event-free survival at 4 years was 79% (95% confidence interval [CI], 70 to 86) in the rituximab group versus 61% (95% CI, 51 to 70) in the observation group (P = 0.001). The rate of progression-free survival at 4 years was 83% (95% CI, 73 to 88) in the rituximab group versus 64% (95% CI, 55 to 73) in the observation group (P <0.001). The rate of overall survival was 89% (95% CI, 81 to 94) in the rituximab group versus 80% (95% CI, 72 to 88) in the observation group (P = 0.04). According to a Cox regression unadjusted analysis, the rate of overall survival at 4 years was higher in the rituximab group than in the observation group (hazard ratio for death, 0.50; 95% CI, 0.26 to 0.99; P = 0.04).” (S.

Changing Tides of the Type 2 Diabetes Epidemic: In the Kelly West Award Lecture for 2016, the recipient notes that “rates of classic diabetes complications have declined in recent decades, representing a major success for people with diabetes as well as clinical and public health efforts that have driven these changes” (pp. 1289–97). “Despite these successes, several currents below the surface of the diabetes epidemic will present major challenges in the coming years. These currents include 1) the continued growth in the numbers of people with diabetes and continued increases in diabetes in youth, 2) a proportional shift in overall complications toward middle-aged adults, the relative persistence of microvascular disease, 3) diversification of diabetes-related morbidity following the reduction in [cardiovascular disease], 4) the continued high levels of diabetes complications in the overall population, and 5) the combined impact of increasing life span and high prevalence on the total years and cumulative morbidity burden in communities. These currents will all play major roles in the course of the diabetes epidemic in the future and will challenge all disciplines of epidemiology to continue to improve the monitoring and understanding of risk factors, risk stratification approaches, and the future prioritization of interventions.” (E. W. Gregg, edg7@cdc.gov)
Alpha-Cell Dysfunction in Chronic Pancreatitis: Results of glucose challenges in patients with diabetes caused by chronic pancreatitis showed similarities to findings in those with type 2 diabetes, researchers report, suggesting a common etiology (pp. 1314–22). A stepwise hypoglycemic clamp and an oral glucose tolerance test (OGTT) showed these results in 10 patients with diabetes secondary to chronic pancreatitis, 13 patients with type 2 diabetes, and 10 healthy control participants: “Glucose levels during the OGTT were higher in patients with diabetes and chronic pancreatitis and lower in control subjects (P <0.0001). Insulin and C-peptide levels were reduced, and the glucose-induced suppression of glucagon was impaired in both groups with diabetes (all P <0.0001 vs. control subjects). During hypoglycemia, glucagon concentrations were reduced in patients with chronic pancreatitis and with type 2 diabetes (P <0.05). The increase in glucagon during the clamp was inversely related to the glucose-induced glucagon suppression and positively related to beta-cell function. Growth hormone responses to hypoglycemia were lower in patients with type 2 diabetes (P = 0.0002) but not in patients with chronic pancreatitis.” (J. J. Meier, juris.meier@rub.de)
Falling Insulin Requirements & Placental Dysfunction: In women with preexisting diabetes, falling insulin requirements during pregnancy should alert clinicians to check for underlying placental dysfunction, a study of 158 women shows (pp. 1323–30; S. Padmanabhan, suja_padman@yahoo.com.au).

* Following a priority review of an agent with a “breakthrough” designation, FDA yesterday approved abemaciclib (Verzenio, Lilly) to treat adult patients who have hormone receptor–positive, human epidermal growth factor receptor 2–negative advanced or metastatic breast cancer that has progressed after endocrine therapy. Abemaciclib is approved for use in combination with the endocrine agent fulvestrant following tumor progression while on endocrine therapy. The agent is also approved for single-agent therapy in patients previously treated with endocrine therapy and chemotherapy after metastasis.
FDA has launched a new user-friendly search tool that improves access to data on adverse events associated with drug and biologic products through the FDA’s Adverse Event Reporting System. The new dashboard enables users to search for and organize data by criteria such as drug/biological product, age of the patient, type of adverse event, year the adverse event occurred, or within a specific timeframe. In addition to making it easier for consumers to search for adverse events reported with drug or biologic products, FDA hopes the increased transparency will spur the submission of more detailed and complete reports from consumers, health care professionals and others, by making it easier for people to see other reports that the FDA receives, and search the database for similar observations.
