Over-the-Counter Supplement Interventions to Prevent Cognitive Decline, Mild Cognitive Impairment, and Clinical Alzheimer-Type Dementia: A Systematic Review: Annals of Internal Medicine: Vol 168, No 1

Background: Optimal interventions to prevent or delay cognitive decline, mild cognitive impairment (MCI), or dementia are uncertain. Purpose: To summarize the evidence on efficacy and harms of over-the-counter (OTC) supplements to prevent or delay cognitive decline, MCI, or clinical Alzheimer-type dementia in adults with normal cognition or MCI but no dementia diagnosis. Data Sources: Multiple electronic databases from 2009 to July 2017 and bibliographies of systematic reviews. Study Selection: English-language trials of at least 6 months' duration that enrolled adults without dementia and compared cognitive outcomes with an OTC supplement versus placebo or active controls. Data Extraction: Extraction performed by a single reviewer and confirmed by a second reviewer; dual-reviewer assessment of risk of bias; consensus determination of strength of evidence. Data Synthesis: Thirty-eight trials with low to medium risk of bias compared ω-3 fatty acids, soy, ginkgo biloba, B vitamins, vitamin D plus calcium, vitamin C or β-carotene, multi-ingredient supplements, or other OTC interventions with placebo or other supplements. Few studies examined effects on clinical Alzheimer-type dementia or MCI, and those that did suggested no benefit. Daily folic acid plus vitamin B12 was associated with improvements in performance on some objectively measured memory tests that were statistically significant but of questionable clinical significance. Moderate-strength evidence showed that vitamin E had no benefit on cognition. Evidence about effects of ω-3 fatty acids, soy, ginkgo biloba, folic acid alone or with other B vitamins, β-carotene, vitamin C, vitamin D plus calcium, and multivitamins or multi-ingredient supplements was either insufficient or low-strength, suggesting that these supplements did not reduce risk for cognitive decline. Adverse events were rarely reported. Limitation: Studies had high attrition and short follow-up and used a highly variable set of cognitive outcome measures. Conclusion: Evidence is insufficient to recommend any OTC supplement for cognitive protection in adults with normal cognition or MCI.

Hydroxychloroquine Effectiveness in Reducing Symptoms of Hand Osteoarthritis: A Randomized Trial: Annals of Internal Medicine: Vol 168, No 6

Background: Synovitis is believed to play a role in producing symptoms in persons with hand osteoarthritis, but data on slow-acting anti-inflammatory treatments are sparse. Objective: To determine the effectiveness of hydroxychloroquine versus placebo as an analgesic treatment of hand osteoarthritis. Design: Randomized, double-blind, placebo-controlled clinical trial with 12-month follow-up. (ISRCTN registry number: ISRCTN91859104) Setting: 13 primary and secondary care centers in England. Participants: Of 316 patients screened, 248 participants (82% women; mean age, 62.7 years) with symptomatic (pain ≥4 on a 0- to 10-point visual analogue scale) and radiographic hand osteoarthritis were randomly assigned and 210 (84.7%) completed the 6-month primary end point. Intervention: Hydroxychloroquine (200 to 400 mg) or placebo (1:1) for 12 months with ongoing usual care. Measurements: The primary end point was average hand pain during the previous 2 weeks (on a 0- to 10-point numerical rating scale [NRS]) at 6 months. Secondary end points included self-reported pain and function, grip strength, quality of life, radiographic structural change, and adverse events. Baseline ultrasonography was done. Results: At 6 months, mean hand pain was 5.49 points in the placebo group and 5.66 points in the hydroxychloroquine group, with a treatment difference of −0.16 point (95% CI, −0.73 to 0.40 point) (P = 0.57). Results were robust to adjustments for adherence, missing data, and use of rescue medication. No significant treatment differences existed at 3, 6, or 12 months for any secondary outcomes. The percentage of participants with at least 1 joint with synovitis was 94% (134 of 143) on grayscale ultrasonography and 59% on power Doppler. Baseline structural damage or synovitis did not affect treatment response. Fifteen serious adverse events were reported (7 in the hydroxychloroquine group [3 defined as possibly related] and 8 in the placebo group). Limitation: Hydroxychloroquine dosage restrictions may have reduced efficacy. Conclusion: Hydroxychloroquine was no more effective than placebo for pain relief in patients with moderate to severe hand pain and radiographic osteoarthritis.

The Relationship of Health Insurance and Mortality: Is Lack of Insurance Deadly?

About 28 million Americans are currently uninsured, and millions more could lose coverage under policy reforms proposed in Congress. At the same time, a growing number of policy leaders have called for going beyond the Patient Protection and Affordable Care Act to a single-payer national health insurance system that would cover every American. These policy debates lend particular salience to studies evaluating the health effects of insurance coverage. In 2002, an Institute of Medicine review concluded that lack of insurance increases mortality, but several relevant studies have appeared since that time. This article summarizes current evidence concerning the relationship of insurance and mortality. The evidence strengthens confidence in the Institute of Medicine's conclusion that health insurance saves lives: The odds of dying among the insured relative to the uninsured is 0.71 to 0.97.

Interventions to Improve Follow-up of Positive Results on Fecal Blood Tests: A Systematic Review: Annals of Internal Medicine: Vol 167, No 8

Background: Fecal immunochemical testing is the most commonly used method for colorectal cancer screening worldwide. However, its effectiveness is frequently undermined by failure to obtain follow-up colonoscopy after positive test results. Purpose: To evaluate interventions to improve rates of follow-up colonoscopy for adults after a positive result on a fecal test (guaiac or immunochemical). Data Sources: English-language studies from the Cochrane Central Register of Controlled Trials, PubMed, and Embase from database inception through June 2017. Study Selection: Randomized and nonrandomized studies reporting an intervention for colonoscopy follow-up of asymptomatic adults with positive fecal test results. Data Extraction: Two reviewers independently extracted data and ranked study quality; 2 rated overall strength of evidence for each category of study type. Data Synthesis: Twenty-three studies were eligible for analysis, including 7 randomized and 16 nonrandomized studies. Three were at low risk of bias. Eleven studies described patient-level interventions (changes to invitation, provision of results or follow-up appointments, and patient navigators), 5 provider-level interventions (reminders or performance data), and 7 system-level interventions (automated referral, precolonoscopy telephone calls, patient registries, and quality improvement efforts). Moderate evidence supported patient navigators and provider reminders or performance data. Evidence for system-level interventions was low. Seventeen studies reported the proportion of test-positive patients who completed colonoscopy compared with a control population, with absolute differences of −7.4 percentage points (95% CI, −19 to 4.3 percentage points) to 25 percentage points (CI, 14 to 35 percentage points). Limitation: More than half of studies were at high or very high risk of bias; heterogeneous study designs and characteristics precluded meta-analysis. Conclusion: Patient navigators and giving providers reminders or performance data may help improve colonoscopy rates of asymptomatic adults with positive fecal blood test results. Current evidence about useful system-level interventions is scant and insufficient. Primary Funding Source: National Cancer Institute. (PROSPERO: CRD42016048286)

Mid- and Long-Term Outcome Comparisons of Everolimus-Eluting Bioresorbable Scaffolds Versus Everolimus-Eluting Metallic Stents: A Systematic Review and Meta-analysis: Annals of Internal Medicine: Vol 167, No 9

Background: Percutaneous coronary interventions to implant bioresorbable vascular scaffolds (BVSs) were designed to reduce the late thrombotic events that occur with metallic stents. Purpose: To estimate the incidence of scaffold thrombosis after BVS implantation and compare everolimus-eluting BVSs with everolimus-eluting metallic stents (EESs) in terms of safety and efficacy at mid- and long-term follow-up in adults who had a percutaneous coronary intervention. Data Sources: PubMed, EMBASE, the Cochrane Library, conference proceedings, and relevant Web sites from inception until 20 May 2017, without language restriction. Study Selection: 7 randomized trials and 38 observational studies (each with a minimum of 6 months and 100 patient-years of follow-up) in adults with coronary artery disease who had a BVS or an EES and reported scaffold or stent thrombosis (main outcome) or other secondary outcomes (such as death, myocardial infarction, or revascularization). Data Extraction: 2 reviewers independently extracted study data, rated study quality, and assessed strength of evidence. Data Synthesis: The pooled incidence of definite or probable scaffold thrombosis after BVS implantation was 1.8% (95% CI, 1.5% to 2.2%) at a median follow-up of 1 year (41 studies, 21 884 patients) and 0.8% (CI, 0.5% to 1.3%) beyond 1 year (14 studies, 4688 patients). Seven trials involving 5578 patients that directly compared BVSs with EESs showed an increased risk for definite or probable scaffold thrombosis (odds ratio [OR], 3.40 [CI, 2.01 to 5.76]) with BVSs at a median follow-up of 25 months. Increased risks were present at early (prominently subacute), late, and very late stages, and odds beyond 1 year were almost double those seen within 1 year. Bioresorbably vascular scaffolds increased risks for myocardial infarction (OR, 1.63 [CI, 1.26 to 2.10]), target lesion revascularization (OR, 1.31 [CI, 1.03 to 1.67]), and target lesion failure (OR, 1.37 [CI, 1.12 to 1.66]); the odds for these 3 end points also increased over time. The incidences of all-cause, cardiac, and noncardiac death and of target vessel and any revascularization did not differ. Limitation: Quality of observational studies was unclear, and some data were unpublished. Conclusion: Compared with EESs, BVSs increased the risks for scaffold thrombosis and other thrombotic events at mid- and long-term follow-up, and risks increased over time.

Curing Hepatitis C Virus Infection: Best Practices From the U.S. Department of Veterans Affairs

The U.S. Department of Veterans Affairs (VA) is the nation's largest care provider for hepatitis C virus (HCV)–infected patients and is uniquely suited to inform national efforts to eliminate HCV. An extensive array of delivery of services, policy guidance, outreach efforts, and funding has broadened the reach and capacity of the VA to deliver direct-acting antiviral (DAA) HCV therapy, supported by an infrastructure to effectively implement change and informed by extensive population health data analysis. The VA has treated more than 92 000 HCV-infected veterans since all-oral DAAs became available in January 2014, with cure rates exceeding 90%; only 51 000 veterans in VA care are known to remain potentially eligible for treatment. Key actions advancing the VA's aggressive treatment of HCV infection that are germane to non-VA settings include expansion of treatment capacity through the use of nonphysician providers, video telehealth, and electronic technologies; expansion of integrated care to address psychiatric and substance use comorbidities; and electronic data tools for patient tracking and outreach. A critical component of effective implementation has been building infrastructure through the creation of regional multidisciplinary HCV Innovation Teams, whose system redesign efforts have produced innovative HCV practice models addressing gaps in care while providing more efficient and effective HCV management for the populations they serve. Financing for HCV treatment and infrastructure resources coupled with reduced drug prices has been paramount to the VA's success in curing HCV infection. The VA is poised to share and extend best practices to other health care organizations and providers delivering HCV care, contributing to a concerted effort to reduce the overall burden of HCV infection.
