RESUMEN
BACKGROUND: Gout is a common type of inflammatory arthritis in patients seen by primary care physicians. PURPOSE: To review evidence about treatment of acute gout attacks, management of hyperuricemia to prevent attacks, and discontinuation of medications for chronic gout in adults. DATA SOURCES: Multiple electronic databases from January 2010 to March 2016, reference mining, and pharmaceutical manufacturers. STUDY SELECTION: Studies of drugs approved by the U.S. Food and Drug Administration and commonly prescribed by primary care physicians, randomized trials for effectiveness, and trials and observational studies for adverse events. DATA EXTRACTION: Data extraction was performed by one reviewer and checked by a second reviewer. Study quality was assessed by 2 independent reviewers. Strength-of-evidence assessment was done by group discussion. DATA SYNTHESIS: High-strength evidence from 28 trials (only 3 of which were placebo-controlled) shows that colchicine, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroids reduce pain in patients with acute gout. Moderate-strength evidence suggests that low-dose colchicine is as effective as high-dose colchicine and causes fewer gastrointestinal adverse events. Moderate-strength evidence suggests that urate-lowering therapy (allopurinol or febuxostat) reduces long-term risk for acute gout attacks after 1 year or more. High-strength evidence shows that prophylaxis with daily colchicine or NSAIDs reduces the risk for acute gout attacks by at least half in patients starting urate-lowering therapy, and moderate-strength evidence indicates that duration of prophylaxis should be longer than 8 weeks. Although lower urate levels reduce risk for recurrent acute attacks, treatment to a specific target level has not been tested. LIMITATION: Few studies of acute gout treatments, no placebo-controlled trials of management of hyperuricemia lasting longer than 6 months, and few studies in primary care populations. CONCLUSION: Colchicine, NSAIDs, and corticosteroids relieve pain in adults with acute gout. Urate-lowering therapy decreases serum urate levels and reduces risk for acute gout attacks.

BACKGROUND: Alternative strategies exist for diagnosing gout that do not rely solely on the documentation of monosodium urate (MSU) crystals. PURPOSE: To summarize evidence regarding the accuracy of clinical tests and classification algorithms compared with that of a reference standard of MSU crystals in joint aspirate for diagnosing gout. DATA SOURCES: Several electronic databases from inception to 29 February 2016. STUDY SELECTION: 21 prospective cohort, cross-sectional, and case-control studies including participants with joint inflammation and no previous definitive gout diagnosis who had MSU analysis of joint aspirate. DATA EXTRACTION: Data extraction and risk-of-bias assessment by 2 reviewers independently; overall strength of evidence (SOE) judgment by group. DATA SYNTHESIS: Recently developed algorithms including clinical, laboratory, and imaging criteria demonstrated good sensitivity (up to 88%) and fair to good specificity (up to 96%) for diagnosing gout (moderate SOE). Three studies of dual-energy computed tomography (DECT) showed sensitivities of 85% to 100% and specificities of 83% to 92% for diagnosing gout (low SOE). Six studies of ultrasonography showed sensitivities of 37% to 100% and specificities of 68% to 97%, depending on the ultrasonography signs assessed (pooled sensitivity and specificity for the double contour sign: 74% [95% CI, 52% to 88%] and 88% [CI, 68% to 96%], respectively [low SOE]). LIMITATION: Important study heterogeneity and selection bias; scant evidence in primary and urgent care settings and in patients with conditions that may be confused with or occur with gout. CONCLUSION: Multidimensional algorithms, which must be validated in primary and urgent care settings, may help clinicians make a provisional diagnosis of gout. Although DECT and ultrasonography also show promise for gout diagnosis, accessibility to these methods may be limited. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

Acupuncture has been suggested as a treatment for posttraumatic stress disorder (PTSD), yet its clinical effects are unclear. This review aims to estimate effects of acupuncture on PTSD symptoms, depressive symptoms, anxiety symptoms, and sleep quality for adults with PTSD. We searched 10 databases in January 2016 to identify eligible randomized controlled trials (RCTs). We performed random effects meta-analyses and examined quality of the body of evidence (QoE) using the GRADE approach to rate confidence in meta-analytic effect estimates. Seven RCTs with 709 participants met inclusion criteria. We identified very low QoE indicating significant differences favoring acupuncture (versus any comparator) at post-intervention on PTSD symptoms (standardized mean difference [SMD] = -0.80, 95% confidence interval [CI] [-1.59, -0.01], 6 RCTs), and low QoE at longer follow-up on PTSD (SMD = -0.46, 95% CI [-0.85, -0.06], 4 RCTs) and depressive symptoms (SMD = -0.56; 95% CI [-0.88, -0.23], 4 RCTs). No significant differences were observed between acupuncture and comparators at post-intervention for depressive symptoms (SMD = -0.58, 95% CI [-1.18, 0.01], 6 RCTs, very low QoE), anxiety symptoms (SMD = -0.82, 95% CI [-2.16, 0.53], 4 RCTs, very low QoE), and sleep quality (SMD = -0.46, 95% CI [-3.95, 3.03], 2 RCTs, low QoE). Safety data (7 RCTs) suggest little risk of serious adverse events, though some participants experienced minor/moderate pain, superficial bleeding, and hematoma at needle insertion sites. To increase confidence in findings, sufficiently powered replication trials are needed that measure all relevant clinical outcomes and dedicate study resources to minimizing participant attrition.

BACKGROUND: The presenting symptoms and rate of progression of multiple sclerosis (MS) are very heterogeneous. The diverse clinical manifestations and the clinical course of the disease may vary with modifiable risk factors. OBJECTIVE: To systematically review modifiable risk factors and exposures associated with MS progression. METHODS: We searched six databases till March 2015, reference-mined reviews, and consulted with experts (PROSPERO 2015:CRD42015016461). Two reviewers screened and extracted data. We used random meta-analysis models and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) to assess the quality of evidence. RESULTS: In total, 59 studies met inclusion criteria. Lower vitamin D levels were associated with higher Expanded Disability Status Scale (EDSS) scores ( r = -0.22; confidence interval (CI) = -0.32, -0.12; 11 studies; I2 = 66%), smokers had an increased risk of MS progression (hazard ratio (HR) = 1.55; CI = 1.10, 2.19; I2 = 72%; seven studies), and there was no association of MS progression with the use of epidural analgesics during childbirth delivery (three studies). There was insufficient evidence to draw conclusions for 11 risk factors due to conflicting results or use of different predictor and outcome measures. CONCLUSION: MS progression was consistently associated with low vitamin D levels, and smoking was associated with a more rapid decline in MS disability. Studies used a variety of methods, predictors, and outcomes making it difficult to draw conclusions. Future studies should focus on prospective assessments.

BACKGROUND: Several risk factors are associated with multiple sclerosis (MS) progression and may be amenable to intervention. OBJECTIVE: To systematically review the evidence for interventions targeting risk factors for MS progression. METHODS: We searched six databases and existing reviews till March 2015 and consulted with experts to identify randomized controlled trials (RCTs) of interventions targeting MS risk factors (PROSPERO 2015:CRD42015016461). RESULTS: In total, 37 RCTs met inclusion criteria. Expanded Disability Status Scale (EDSS) scores after exercise interventions did not differ compared with untreated controls (standardized mean differences (SMDs): 0.02; confidence interval (CI): -0.40, 0.44; I2: 0%; seven RCTs; very low quality of evidence (QoE)). Dietary interventions did not show a statistically significant effect on the relative risk (RR) of progression (RR: 0.86; CI: 0.67, 1.05; I2: 0%; four RCTs; moderate QoE) compared to placebo. EDSS scores after vitamin D supplementation were not significantly different from placebo (SMD: -0.15; CI: -0.33, 0.02; I2: 0%; five RCTs; very low QoE). CONCLUSION: We did not identify any risk factor interventions with significant effects on MS progression, but the overall QoE was limited. More adequately powered trials are needed on vitamin D supplementation, long-term exercise, and smoking cessation.

BACKGROUND: Chronic pain patients increasingly seek treatment through mindfulness meditation. PURPOSE: This study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults. METHOD: We conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use. RESULTS: Thirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life. CONCLUSIONS: While mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.

CONTEXT: Probiotics are live microorganisms intended to confer a health benefit when consumed. One condition for which probiotics have been advocated is the diarrhea that is a common adverse effect of antibiotic use. OBJECTIVE: To evaluate the evidence for probiotic use in the prevention and treatment of antibiotic-associated diarrhea (AAD). DATA SOURCES: Twelve electronic databases were searched (DARE, Cochrane Library of Systematic Reviews, CENTRAL, PubMed, EMBASE, CINAHL, AMED, MANTIS, TOXLINE, ToxFILE, NTIS, and AGRICOLA) and references of included studies and reviews were screened from database inception to February 2012, without language restriction. STUDY SELECTION: Two independent reviewers identified parallel randomized controlled trials (RCTs) of probiotics (Lactobacillus, Bifidobacterium, Saccharomyces, Streptococcus, Enterococcus, and/or Bacillus) for the prevention or treatment of AAD. DATA EXTRACTION: Two independent reviewers extracted the data and assessed trial quality. RESULTS: A total of 82 RCTs met inclusion criteria. The majority used Lactobacillus-based interventions alone or in combination with other genera; strains were poorly documented. The pooled relative risk in a DerSimonian-Laird random-effects meta-analysis of 63 RCTs, which included 11 811 participants, indicated a statistically significant association of probiotic administration with reduction in AAD (relative risk, 0.58; 95% CI, 0.50 to 0.68; P < .001; I(2), 54%; [risk difference, -0.07; 95% CI, -0.10 to -0.05], [number needed to treat, 13; 95% CI, 10.3 to 19.1]) in trials reporting on the number of patients with AAD. This result was relatively insensitive to numerous subgroup analyses. However, there exists significant heterogeneity in pooled results and the evidence is insufficient to determine whether this association varies systematically by population, antibiotic characteristic, or probiotic preparation. CONCLUSIONS: The pooled evidence suggests that probiotics are associated with a reduction in AAD. More research is needed to determine which probiotics are associated with the greatest efficacy and for which patients receiving which specific antibiotics.

BACKGROUND: Whether collaborative care models that enable interactive communication (timely, 2-way exchange of pertinent clinical information directly between primary care and specialist physicians) improve patient outcomes is uncertain. PURPOSE: To assess the effects of interactive communication between collaborating primary care physicians and key specialists on outcomes for patients receiving ambulatory care. DATA SOURCES: PubMed, PsycInfo, EMBASE, CINAHL, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, and Web of Science through June 2008 and secondary references, with no language restriction. STUDY SELECTION: Studies that evaluated the effects of interactive communication between collaborating primary care physicians and specialists on outcomes for patients with diabetes, psychiatric conditions, or cancer. DATA EXTRACTION: Contextual, intervention, and outcome data from 23 studies were extracted by one reviewer and checked by another. Study quality was assessed with a 13-item checklist. Disagreement was resolved by consensus. Main outcomes for analysis were selected by reviewers who were blinded to study results. DATA SYNTHESIS: Meta-analysis indicated consistent effects across 11 randomized mental health studies (pooled effect size, -0.41 [95% CI, -0.73 to -0.10]), 7 nonrandomized mental health studies (pooled effect size, -0.47 [CI, -0.84 to -0.09]), and 5 nonrandomized diabetes studies (pooled effect size, -0.64 [CI, -0.93 to -0.34]). These findings remained robust to sensitivity analyses. Meta-regression indicated studies that included interventions to enhance the quality of information exchange had larger effects on patient outcomes than those that did not (-0.84 vs. -0.27; P = 0.002). LIMITATIONS: Because collaborative interventions were inherently multifaceted, the efficacy of interactive communication by itself cannot be established. Inclusion of study designs with lower internal validity increased risk for bias. No studies involved oncologists. CONCLUSION: Consistent and clinically important effects suggest a potential role of interactive communication for improving the effectiveness of primary care-specialist collaboration.

This systematic review addresses the question: What are the effects of medication-assisted treatment (MAT) that use buprenorphine, buprenorphine combined with naloxone, methadone, or naltrexone for opioid use disorder (OUD) on functional outcomes compared with wait-list, placebo, treatment without medication, any other comparator, or each other (e.g., buprenorphine versus naltrexone)? Functional outcomes investigated included cognitive (e.g., memory), physical (e.g., fatigue), occupational (e.g., employment status), social/behavioral (e.g., criminal activity), and neurological (e.g., balance) function. The authors searched five scientific research databases from inception to 2017 and reference mined existing reviews. Two independent literature reviewers screened 6,292 citations; 1,327 full-text publications were reviewed in detail and 37 studies met inclusion criteria. Critical appraisals assessed studies in detail, and quality of evidence was rated using established criteria. Results were synthesized in meta-analyses and presented in comprehensive evidence tables. Although MAT patients performed significantly better on some functional outcomes than persons with OUD who did not receive MAT, MAT patients performed worse on several cognitive measures than did matched "healthy" controls with no history of substance use disorder (SUD) or OUD. Because of the moderate-to-high risk of bias of most studies, quality of evidence is low or very low for all findings. The small number of studies reporting on outcomes of interest and the weaknesses in the body of evidence prevent making strong conclusions about MAT effects on functional outcomes. The literature shows that more research is needed that targets functional outcomes specifically, and there is, in particular, a lack of research evaluating potential differences in functional effects among medication types, the route of administration, treatment modality, and length of treatment.
RESUMEN
Objectives: Massage therapy has been proposed for painful conditions, but it can be difficult to understand the breadth and depth of evidence, as various painful conditions may respond differently to massage. The authors conducted an evidence mapping process and generated an "evidence map" to visually depict the distribution of evidence available for massage and various pain indications to identify gaps in evidence and to inform future research priorities. Design: The authors searched PubMed, Embase, and Cochrane for systematic reviews reporting pain outcomes for massage therapy. The authors assessed the quality of each review using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) criteria. The authors used a bubble plot to depict the number of included articles, pain indication, effect of massage for pain, and strength of findings for each included systematic review. Results: The authors identified 49 systematic reviews, of which 32 were considered high quality. Types of pain frequently included in systematic reviews were cancer pain, low back pain, and neck pain. High quality reviews concluded that there was low strength of evidence of potential benefits of massage for labor, shoulder, neck, low back, cancer, arthritis, postoperative, delayed onset muscle soreness, and musculoskeletal pain. Reported attributes of massage interventions include style of massage, provider, co-interventions, duration, and comparators, with 14 high-quality reviews reporting all these attributes in their review. Conclusion: Prior reviews have conclusions of low strength of evidence because few primary studies of large samples with rigorous methods had been conducted, leaving evidence gaps about specific massage type for specific pain. Primary studies often do not provide adequate details of massage therapy provided, limiting the extent to which reviews are able to draw conclusions about characteristics such as provider type.

BACKGROUND: Mindfulness interventions aim to foster greater attention and awareness of present moment experiences. Uptake of mindfulness programs in the workplace has grown as organizations look to support employee health, wellbeing, and performance. OBJECTIVE: In support of evidence-based decision making in workplace contexts, we created an evidence map summarizing physical and mental health, cognitive, affective, and interpersonal outcomes from systematic reviews of randomized controlled trials (RCTs) of mindfulness interventions. METHODS: We searched nine electronic databases to July 2017, dually-screened all reviews, and consulted topic experts to identify systematic reviews on mindfulness interventions. The distribution of evidence is presented as an evidence map in a bubble plot. RESULTS: In total, 175 systematic reviews met inclusion criteria. Reviews included a variety of mindfulness-based interventions. The largest review included 109 randomized controlled trials. The majority of these addressed general health, psychological conditions, chronic illness, pain, and substance use. Twenty-six systematic reviews assessed studies conducted in workplace settings and with healthcare professionals, educators, and caregivers. The evidence map shows the prevalence of research by the primary area of focus. An outline of promising applications of mindfulness interventions is included. CONCLUSIONS: The evidence map provides an overview of existing mindfulness research. It shows the body of available evidence to inform policy and organizational decision-making supporting employee wellbeing in work contexts.

Caring for women with gynecologic malignancies requires multidisciplinary communication and coordination across multiple providers. This article discusses a rapid review of the literature on characteristics of care coordination for gynecologic malignancies. Five electronic databases (from inception through March 2015) were searched for empirical studies on coordinated care models for female adults with gynecologic malignancies. A single reviewer extracted and synthesized information on how care was coordinated, how care teams made decisions, who performed what tasks, how care teams communicated information to coordinate care, and potential impact of the characteristic on delivering coordinated care. From 26 included studies, predominant characteristics of coordinated care were identified: multidisciplinary teams, patient navigators, scheduled follow-ups, survivorship care plans, and colocated services. Decision-making was best documented for studies that utilized teams that had periodic scheduled meetings with set agendas and consistent procedures. Providers' roles in coordinating care were numerous, reflecting professional backgrounds: oncologists had most authority in making treatment decisions; radiologists and pathologists shared vital biomedical information; and nurses coordinated care and communicated with patients. Communication tools and strategies across studies included having shared medical records, integrated treatment plans, and telephone-based or teleconferencing communication. There was limited information available on the impact of characteristics and accompanying strategies or tools. Several characteristics of care coordination models for gynecologic cancers have been published in the literature. Further investigation is needed to understand the relative effectiveness of these ways to coordinate care.

OBJECTIVE: Depression is a highly prevalent clinical condition. The use of technologies in the clinical care of depressive disorders may increase the reach of clinical services for these disorders and support more comprehensive treatment. The objective of this evidence map is to provide an overview of the use of technology in the clinical care of depression. DATA SOURCES: We searched PubMed, PsycINFO, and the Web of Science from inception to June 2017 to identify published randomized controlled trials (RCTs). STUDY SELECTION: Two reviewers used predetermined eligibility criteria to review 4,062 records and include 161 RCTs that met our inclusion criteria. We include studies evaluating any type of treatment-related technology in the clinical care of depression. DATA EXTRACTION: We extracted data on sample sizes, the type of technology examined, the function of that technology, the effectiveness of the technology, and publication year. RESULTS: Out of 161 RCTs, we found the greatest amount of research for psychotherapy by computer (51 RCTs). The majority of studies were published after 2012 (94 RCTs; 58%). Few published studies involved videoconferences or smartphones, or provider feedback or auto-reminders. 145 studies (90%) reported that the intervention had a positive outcome of symptom improvement compared to baseline. CONCLUSIONS: This evidence map provides a broad overview of the existing research evaluating technology in depression care. Computer applications are still most common. Almost all applications yield symptom improvement. More information is needed to evaluate the role of technology in clinical care.

CONTEXT: Influenza vaccination rates remain below Healthy People 2020 goals. This project sought to systematically review economic evaluations of healthcare-based quality improvement interventions for improving influenza vaccination uptake among general populations and healthcare workers. EVIDENCE ACQUISITION: The databases MEDLINE, Econlit, Centre for Reviews & Dissemination, Greylit, and Worldcat were searched in July 2016 for papers published from January 2004 to July 2016. Eligible studies evaluated efforts by bodies within the healthcare system to encourage influenza vaccination by means of an organizational or structural change. For each study, program costs per enrollee and per additional enrollee vaccinated were derived (excluding vaccine costs, standardized to 2017 U.S. dollars). Complete economic evaluations were examined when available. EVIDENCE SYNTHESIS: Of 2,350 records, 18 articles were eligible and described 29 unique interventions. Most interventions improved vaccine uptake. Among 23 interventions in general populations, the median program cost was $3.27 (interquartile range, $0.82-$11.53) per enrollee and $50.78 (interquartile range, $27.85-$124.84) per additional enrollee vaccinated. Among ten complete economic evaluations in general populations, three studies reported net cost savings, four reported costs <$50,000 per quality-adjusted life year, and three reported costs <$60,000 per life saved. Among six interventions in healthcare workers, the median program cost was $8.09 (interquartile range, $5.03-$10.31) per worker enrolled and $125.24 (interquartile range, $96.06-$171.38) per additional worker vaccinated (there were no complete economic analyses). CONCLUSIONS: Quality improvement interventions for influenza vaccination involve per-enrollee costs that are similar to the cost of the vaccine itself ($11.78-$36.08/dose). Based on limited available evidence in general populations, quality improvement interventions may be cost saving to cost effective for the health system.

OBJECTIVE: Quality improvement (QI) interventions can improve glycemic control, but little is known about their value. We systematically reviewed economic evaluations of QI interventions for glycemic control among adults with type 1 or type 2 diabetes. RESEARCH DESIGN AND METHODS: We used English-language studies from high-income countries that evaluated organizational changes and reported program and utilization-related costs, chosen from PubMed, EconLit, Centre for Reviews and Dissemination, New York Academy of Medicine's Grey Literature Report, and WorldCat (January 2004 to August 2016). We extracted data regarding intervention, study design, change in HbA1c, time horizon, perspective, incremental net cost (studies lasting ≤3 years), incremental cost-effectiveness ratio (ICER) (studies lasting ≥20 years), and study quality. Weighted least-squares regression analysis was used to estimate mean changes in HbA1c and incremental net cost. RESULTS: Of 3,646 records, 46 unique studies were eligible. Across 19 randomized controlled trials (RCTs), HbA1c declined by 0.26% (95% CI 0.17-0.35) or 3 mmol/mol (2 to 4) relative to usual care. In 8 RCTs lasting ≤3 years, incremental net costs were $116 (95% CI -$612 to $843) per patient annually. Long-term ICERs were $100,000-$115,000/quality-adjusted life year (QALY) in 3 RCTs, $50,000-$99,999/QALY in 1 RCT, $0-$49,999/QALY in 4 RCTs, and dominant in 1 RCT. Results were more favorable in non-RCTs. Our limitations include the fact that the studies had diverse designs and involved moderate risk of bias. CONCLUSIONS: Diverse multifaceted QI interventions that lower HbA1c appear to be a fair-to-good value relative to usual care, depending on society's willingness to pay for improvements in health.

This systematic review synthesizes evidence on the effects of Medication-Assisted Treatment (MAT) for opioid use disorder (OUD) on functional outcomes, including cognitive (e.g., memory), physical (e.g., fatigue), occupational (e.g., return to work), social/behavioral (e.g., criminal activity), and neurological (e.g., balance) function. Five databases were searched from inception to July 2017 to identify English-language controlled trials, case control studies, and cohort comparisons of one or more groups; cross-sectional studies were excluded. Two independent reviewers screened identified literature, abstracted study-level information, and assessed the quality of included studies. Meta-analyses used the Hartung-Knapp method for random-effects models. The quality of evidence was assessed using the GRADE approach. A comprehensive search followed by 1411 full text publication screenings yielded 30 randomized controlled trials (RCTs) and 10 observational studies meeting inclusion criteria. The studies reported highly diverse functional outcome measures. Only one RCT was rated as high quality, but several methodologically sound observational studies were identified. The statistical power to detect differences in functional outcomes was unclear in most studies. When compared with matched "healthy" controls with no history of substance use disorder (SUD), in two studies MAT patients had significantly poorer working memory and cognitive speed. One study found MAT patients scored worse in aggressive responding than did "healthy" controls. A large observational study found that MAT users had twice the odds of involvement in an injurious traffic accident as non-users. When compared with persons with OUD not on MAT, one cohort study found lower fatigue rates among buprenorphine-treated OUD patients. No differences were reported for occupational outcomes and results for criminal activity and other social/behavioral areas were mixed. There were few differences among MAT drug types. A pooled analysis of three RCTs found a significantly lower prevalence of fatigue with buprenorphine compared to methadone, while a meta-analysis of the same RCTs found no statistical difference in insomnia prevalence. Three RCTs that focused on cognitive function compared the effects of buprenorphine to methadone; no statistically significant differences in memory, cognitive speed and flexibility, attention, or vision were reported. The quality of evidence for most functional outcomes was rated low or very low. In sum, weaknesses in the body of evidence prevent strong conclusions about the effects of MAT for opioid use disorder on functional outcomes. Rigorous studies of functional effects would strengthen the body of literature.

BACKGROUND: The correct perioperative management of antiplatelet therapy (APT) in patients undergoing non-cardiac surgery (NCS) is often debated by clinicians. American College of Cardiology (ACC) and American Heart Association (AHA) guidelines recommend postponing elective NCS at least 3 months after stent implantation. Regardless of the timing of surgery, ACC/AHA guidelines recommend continuing at least ASA throughout the perioperative period and ideally continuing dual APT (DAPT) therapy "unless surgery demands discontinuation." The objective of this review was to ascertain the risks and benefits of APT in the perioperative period, to assess how these risks and benefits vary by APT management, and the significance of length of time since stent implantation before operative intervention. METHODS: PubMed, Web of Science, and Scopus were searched from inception through October 2017. Articles were included if patients were post PCI with stent placement (bare metal [BMS] or drug eluting [DES]), underwent elective NCS, and had rates of major adverse cardiac events (MACE) or bleeding events associated with pre and perioperative APT therapy. RESULTS: Of 4882 screened articles, we included 16 studies in the review (1 randomized controlled trial and 15 observational studies). Studies were small (< 50: n = 5, 51-150: n = 5, >150: n = 6). All studies included DES with 7 of 16 also including BMS. Average time from stent to NCS was variable (< 6 months: n = 3, 6-12 months: n = 1, > 12 months: n = 6). At least six different APT strategies were described. Six studies further utilized bridging protocols using three different pharmacologic agents. Studies typically included multiple surgical fields with varying degrees of invasiveness. Across all APT strategies, rates of MACE/bleeding ranged from 0 to 21% and 0 to 22%. There was no visible trend in MACE/bleeding rates within a given APT strategy. Stratifying the articles by type of surgery, timing of discontinuation of APT therapy, bridging vs. no bridging, and time since stent placement did not help explain the heterogeneity. CONCLUSIONS: Evidence regarding perioperative APT management in patients with cardiac stents undergoing NCS is insufficient to guide practice. Other clinical factors may have a greater impact than perioperative APT management on MACE and bleeding events. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016036607.

OBJECTIVES: Substance use disorder (SUD) is a prevalent health issue with serious personal and societal consequences. This review aims to estimate the effects and safety of Mindfulness-based Relapse Prevention (MBRP) for SUDs. METHODS: We searched electronic databases for randomized controlled trials evaluating MBRP for adult patients diagnosed with SUDs. Two reviewers independently assessed citations, extracted trial data, and assessed risks of bias. We conducted random-effects meta-analyses and assessed quality of the body of evidence (QoE) using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: We identified 9 randomized controlled trials comprising 901 participants. We did not detect statistically significant differences between MBRP and comparators on relapse (odds ratio [OR] 0.72, 95% confidence interval [CI] 0.46-1.13, low QoE), frequency of use (standardized mean difference [SMD] 0.02, 95% CI -0.40 to 0.44, low QoE), treatment dropout (OR 0.81, 95% CI 0.40 to 1.62, very low QoE), depressive symptoms (SMD -0.09, 95% CI -0.39 to 0.21, low QoE), anxiety symptoms (SMD -0.32, 95% CI -1.16 to 0.52, very low QoE), and mindfulness (SMD -0.28, 95% CI -0.72 to 0.16, very low QoE). We identified significant differences in favor of MBRP on withdrawal/craving symptoms (SMD -0.13, 95% CI -0.19 to -0.08, Iâ=â0%, low QoE) and negative consequences of substance use (SMD -0.23, 95% CI -0.39 to -0.07, Iâ=â0%, low QoE). We found negligible evidence of adverse events. CONCLUSIONS: We have limited confidence in estimates suggesting MBRP yields small effects on withdrawal/craving and negative consequences versus comparator interventions. We did not detect differences for any other outcome. Future trials should aim to minimize participant attrition to improve confidence in effect estimates.
