Background: Clinical exposure to Pediatric and Adolescent Gynecology (PAG) varies amongst residency programs 1,2. In areas such as PAG where clinical exposure may be limited, residents need solid evidence-based practice (EBP) skills to guide future independent practice. The OSCE format presents an opportunity to simulate a clinical scenario that residents may not encounter in their training, objectively assess performance, and increase learner motivation to continue building skills. This study evaluates resident performance on an EBP OSCE station based on a core PAG topic in order to evaluate its ability to provide program-level evaluation of the skills of evidence-based practice in PAG and provide actionable feedback to learners.
Method(s): A hybrid simulation/OSCE station was developed to assess core skills of EBP in the management of labial adhesions. A behaviorally anchored scoring checklist was developed for each component of the station and scored separately and independently by a single medical librarian and standardized patient. Mixed methods evaluation of performance by residents of all levels of residency training was done, focusing on quantitative analysis of EBP performance with thematic analysis of qualitative evaluation data.
Result(s): 30 Obstetrics and Gynecology residents participated in the PAG EBP OSCE station (9 PGY1, 10 PGY2, 6 PGY3, 5 PGY4). The overall mean score for all residents was 57% (+/- 18 SD). Mean scores by PGY increased between first and second year, but did not increase further in later years of training with the largest variation in performance in the PGY4 year (Figure 1). Thematic analysis of the qualitative feedback on residents' search strategies revealed useful insights at a programmatic level (Table 1). Upper level residents often used a less robust search strategy of the literature, instead opting for a database they had some familiarity with to guide their recommendations without searching for corroborating evidence or additional sources.
Conclusion(s): OSCE provides a feasible standardized way to observe, assess and encourage development of core EBP skills. A slight developmental trend was seen with improving scores among junior residents between the first and second years of training. However, this trend did not continue between the final years of training. The fact that scores did not increase linearly suggests that clinical training may not reinforce EBP skills. The importance of EBP skills is magnified in PAG where clinical exposure and experience amongst trainees may be limited. In addition to improving resident education in PAG, medical educators must continue to develop and implement interventions to teach and reinforce EBP skills to trainees to bring to future independent practice.

The Federal Bureau of Investigation (FBI) defines an active shooter as "an individual actively engaged in killing or attempting to kill people in a confined and populated area".¹ A study of newspaper articles and press releases identified 154 active shooter incidents (ASIs) in hospitals in the United States in the 12-year period 2000-2011.² ASIs were more common in larger hospitals, with 29% taking place in the emergency department (ED) and 19% in patient rooms. In 50% of the ASIs in an ED, the perpetrator used a security officer's gun.

OBJECTIVES/OBJECTIVE:Double fascicular transfer is argued to result in improved elbow flexion compared to the traditional ulnar fascicular transfer because it reinnervates both the biceps and the brachialis. This study seeks to determine if double fascicular transfer should be preferred over ulnar fascicular transfer to restore elbow flexion in patients with upper trunk brachial plexus injuries (BPI) by analyzing the current database of literature on the topic. METHODS:A systematic review was conducted according to PRISMA guidelines. Inclusion criteria were studies reporting Medical Research Council (MRC) scores on individual patients undergoing ulnar fascicular transfer and double fascicular transfer (ulnar and median nerve fascicle donors). Patients were excluded if: age < 18 years old and follow-up <12 months. Demographics obtained include age, sex, extent of injury (C5-C6/C5-C7), preoperative interval, procedure type, and follow-up time. Outcomes included absolute MRC score and ability to achieve MRC score ≥3 and ≥4. Univariate and multivariate regression analyses were completed to evaluate predictors of postoperative outcomes. RESULTS:Eighteen studies (176 patients) were included for pooled analysis. Patients that underwent double fascicular transfer had a higher percentage of patients attain a MRC score ≥ 4 compared to ulnar fascicular transfer subjects (83.0% vs. 63.3%, p = .013). Double fascicular transfer was a predictor of achieving high MRC scores (OR = 2.829, p = .015). Multivariate analysis showed that procedure type was the only near significant predictor of ability to obtain MRC ≥4 (OR: 2.338, p = .054). CONCLUSIONS:This analysis demonstrates that double fascicular transfer is associated with superior postoperative outcomes and should be performed for restoring elbow flexion.

INTRODUCTION/BACKGROUND:Prediction models for gestational hypertension and preeclampsia have been developed with data and assumptions from developed countries. Their suitability and application for low resource settings have not been tested. This review aimed to identify and assess the methodological quality of prediction models for gestational hypertension and pre-eclampsia with reference to their application in low resource settings. METHODS:Using combinations of keywords for gestational hypertension, preeclampsia and prediction models seven databases were searched to identify prediction models developed with maternal data obtained before 20 weeks of pregnancy and including at least three predictors (Prospero registration CRD 42017078786). Prediction model characteristics and performance measures were extracted using the CHARMS, STROBE and TRIPOD checklists. The National Institute of Health quality assessment tools for observational cohort and cross-sectional studies were used for study quality appraisal. RESULTS:We retrieved 8,309 articles out of which 40 articles were eligible for review. Seventy-seven percent of all the prediction models combined biomarkers with maternal clinical characteristics. Biomarkers used as predictors in most models were pregnancy associated plasma protein-A (PAPP-A) and placental growth factor (PlGF). Only five studies were conducted in a low-and middle income country. CONCLUSIONS:Most of the studies evaluated did not completely follow the CHARMS, TRIPOD and STROBE guidelines in prediction model development and reporting. Adherence to these guidelines will improve prediction modelling studies and subsequent application of prediction models in clinical practice. Prediction models using maternal characteristics, with good discrimination and calibration, should be externally validated for use in low and middle income countries where biomarker assays are not routinely available.

BACKGROUND:A severe neurological disorder, Guillain-Barré syndrome (GBS) is the leading cause of acute flaccid paralysis. Enhanced surveillance of GBS in Latin America and the Caribbean (LAC) following the 2015-2016 Zika virus (ZIKV) epidemic presents an opportunity to estimate, for the first time, the regional incidence of GBS. METHODS AND FINDINGS/RESULTS:For this systematic review and meta-analysis, we searched nine scientific databases and grey literature from January 1, 1980 to October 1, 2018. Sources with primary data on incident GBS cases in LAC within a well-defined population and timeframe, published in English, Spanish, Portuguese, or French, were included. We calculated the annual GBS incidence rates (IRs) and 95% confidence intervals (CIs) for each source based on published data. Following an assessment of heterogeneity, we used random-effects meta-analysis to calculate the pooled annual IR of GBS. The study is registered with PROSPERO, number CRD42018086659. Of the 6586 initial citation hits, 31 were eligible for inclusion. Background annual GBS IRs in Latin America ranged from 0.40 in Brazil to 2.12/100,000 in Chile. The pooled annual IR in the Caribbean was 1.64 (95% CI 1.29-2.12, I2<0.01, p = 0.44). During the ZIKV epidemic, GBS IRs ranged from 0.62 in Mexico to 9.35/100,000 in Martinique. GBS increased 2.6 (95% CI 2.3-2.9) times during ZIKV and 1.9 (95% CI 1.1-3.4) times during chikungunya outbreaks over background rates. A limitation of this review is that the studies included employed different methodologies to find and ascertain cases of GBS, which could contribute to IR heterogeneity. In addition, it is important to consider that data on GBS are lacking for many countries in the region. CONCLUSIONS:Background IRs of GBS appear to peak during arboviral disease outbreaks. The current review contributes to an understanding of the epidemiology of GBS in the LAC region, which can inform healthcare system planning and preparedness, particularly during arboviral epidemics. TRIAL REGISTRATION/BACKGROUND:Registered with PROSPERO: CRD42018086659.

Objective: The purpose of this study was to assess the association between extent of brachial plexus injury and shoulder abduction/external rotation outcomes after spinal accessory nerve (SAN) to suprascapular nerve (SSN) transfer. Methods: A systematic review of the literature was conducted according to PRISMA guidelines. Inclusion criteria were studies reporting outcomes on patients undergoing SAN to SSN nerve transfer. Patients were excluded for the following reasons: age under 18, nerve transfer for reanimation of the shoulder other than SAN to SSN, and less than 12 months of follow-up postoperatively. Pooled analysis was performed, and primary outcomes were Medical Research Council (MRC) score and range of motion (ROM) for shoulder abduction and external rotation. Univariate logistic regression analysis was used to assess the association between extent of brachial plexus injury and shoulder abduction/external rotation outcomes after SAN to SSN transfer. A multivariate logistic regression analysis model including age, injury to surgery interval, and extent of injury as factors was also created. Results: Univariate logistic regression analysis showed greater extent of injury to be a predictor of poorer shoulder abduction outcomes (OR: 0.502; 95% CI: 0.260-0.971, p = 0.040). Multivariate logistic regression analysis confirmed this association (OR: 0.55; 95% CI: 0.236-0.877, p = 0.019). Extent of injury was not significantly associated with external rotation outcomes on univariate analysis (OR: 0.435; 95% CI: 0.095-1.995, p = 0.284) or multivariate analysis (OR: 0.445; 95% CI: 0.097-2.046, p = 0.298). Age and injury to surgery interval were not significantly associated with postoperative outcomes. Conclusions: More extensive brachial plexus injuries are associated with inferior outcomes after SAN to SSN transfer. A potential explanation for this finding includes lost contribution of muscles from the shoulder girdle that receive innervation from outside of the upper brachial plexus. The relationship between extent of injury and postoperative outcomes is important to recognize when determining and discussing operative intervention with patients.

OBJECTIVE:A review of the implementation outcomes of clean cookstove use, and its effects on blood pressure (BP) in low-income and middle-income countries (LMICs). DESIGN/METHODS:Systematic review of studies that reported the effect of clean cookstove use on BP among women, and implementation science outcomes in LMICs. DATA SOURCES/METHODS:We searched PubMed, Embase, INSPEC, Scielo, Cochrane Library, Global Health and Web of Science PLUS. We conducted searches in November 2017 with a repeat in May 2018. We did not restrict article publication date. ELIGIBILITY CRITERIA FOR SELECTING STUDIES/UNASSIGNED:We included only studies conducted in LMICs, published in English, regardless of publication year and studies that examined the use of improved or clean cookstove intervention on BP. Two authors independently screened journal article titles, abstracts and full-text articles to identify those that included the following search terms: high BP, hypertension and or household air pollution, LMICs, cookstove and implementation outcomes. RESULTS:Of the 461 non-duplicate articles identified, three randomised controlled trials (RCTs) (in Nigeria, Guatemala and Ghana) and two studies of pre-post design (in Bolivia and Nicaragua) met eligibility criteria. These articles evaluated the effect of cookstove use on BP in women. Two of the three RCTs reported a mean reduction in diastolic BP of -2.8 mm Hg (-5.0, -0.6; p=0.01) for the Nigerian study; -3.0 mm Hg; (-5.7, -0.4; p=0.02) for the Guatemalan study; while the study conducted in Ghana reported a non-significant change in BP. The pre-post studies reported a significant reduction in mean systolic BP of -5.5 mm Hg; (p=0.01) for the Bolivian study, and -5.9 mm Hg (-11.3, -0.4; p=0.05) for the Nicaraguan study. Implementation science outcomes were reported in all five studies (three reported feasibility, one reported adoption and one reported feasibility and adoption of cookstove interventions). CONCLUSION/CONCLUSIONS:Although this review demonstrated that there is limited evidence on the implementation of clean cookstove use in LMICs, the effects of clean cookstove on BP were significant for both systolic and diastolic BP among women. Future studies should consider standardised reporting of implementation outcomes.

OBJECTIVE/UNASSIGNED:Workplace-based employee health promotion programs often target weight loss or physical activity, yet there is growing attention to sleep as it affects employee health and performance. The goal of this review is to systematically examine workplace-based employee health interventions that measure sleep duration as an outcome. DATA SOURCE/UNASSIGNED:We conducted systematic searches in PubMed, Web of Knowledge, EMBASE, Scopus, and PsycINFO (n = 6177 records). STUDY INCLUSION AND EXCLUSION CRITERIA/UNASSIGNED:To be included in this systematic review, studies must include (1) individuals aged >18 years, (2) a worker health-related intervention, (3) an employee population, and (4) sleep duration as a primary or secondary outcome. RESULTS/UNASSIGNED:Twenty studies met criteria. Mean health promotion program duration was 2.0 months (standard deviation [SD] = 1.3), and mean follow-up was 5.6 months (SD = 6.5). The mean sample size of 395 employees (SD = 700.8) had a mean age of 41.5 years (SD = 5.2). Measures of sleep duration included self-report from a general questionnaire (n = 12, 66.6%), self-report based on Pittsburgh Sleep Quality Index (n = 4, 22.2%), and self-report and actigraphy combined (n = 5, 27.7%). Studies most commonly included sleep hygiene (35.0%), yoga (25.0%), physical activity (10.0%), and cognitive-behavioral therapy for insomnia (10.0%) interventions. Across the interventions, 9 different behavior change techniques (BCTs) were utilized; the majority of interventions used 3 or fewer BCTs, while 1 intervention utilized 4 BCTs. Study quality, on average, was 68.9% (SD = 11.1). Half of the studies found workplace-based health promotion program exposure was associated with a desired increase in mean nightly sleep duration (n = 10, 50.0%). CONCLUSIONS/UNASSIGNED:Our study findings suggest health promotion programs may be helpful for increasing employee sleep duration and subsequent daytime performance.

Purpose of review/UNASSIGNED:To systematically review the available research studies that characterize the benefits, uncertainty, or weaknesses of commercially-available sleep tracking technology. Recent findings/UNASSIGNED:Sleep is a vital component of health and well-being. Research shows that tracking sleep using commercially available sleep tracking technology (e.g., wearable or smartphone-based) is increasingly popular in the general population. Methods/UNASSIGNED:Systematic literature searches were conducted using PubMed/Medline, Embase (Ovid) the Cochrane Library, PsycINFO (Ovid), CINAHL, and Web of Science Plus (which included results from Biosis Citation Index, INSPEC, and Food, Science & Technology Abstracts) (n=842). Study Inclusion and Exclusion Criteria/UNASSIGNED:Three independent reviewers reviewed eligible articles that administered a commercially-available sleep tracker to participants and reported on sleep parameters as captured by the tracker, including either sleep duration or quality. Eligible articles had to include sleep data from users for >=4 nights.

BACKGROUND:Integrated cardiovascular disease (CVD) and HIV (CVD-HIV) care interventions are being adopted to tackle the growing burden of noncommunicable diseases (NCDs) in low-and middle-income countries (LMICs) but there is a paucity of studies on the feasibility of these interventions in LMICs. This scoping review aims to present evidence of the feasibility of integrated CVD-HIV care in LMICs, and the alignment of feasibility reporting in LMICs with the existing implementation science methodology. METHODS:A systematic search of published articles including systematic and narrative reviews that reported on integrated CVD-HIV care was conducted, using multiple search engines including PubMed/Medline, Global Health, and Web of Science. We examined the articles for evidence of feasibility reporting. Adopting the definition of Proctor and colleagues (2011), feasibility was defined as the extent to which an intervention was plausible in a given agency or setting. Evidence from the articles was synthesized by level of integration, the chronic care continuum, and stages of intervention development. RESULTS:Twenty studies, reported in 18 articles and 3 conferences abstracts, reported on feasibility of integrated CVD-HIV care interventions. These studies were conducted in Sub-Saharan Africa, Southeast Asia and South America. Four of these studies were conducted as feasibility studies. Eighty percent of the studies reported feasibility, using descriptive sentences that included words synonymous with feasibility terminologies in existing definition recommended by Proctor and colleagues. There was also an overlap in the use of descriptive phrases for feasibility amongst the selected studies. CONCLUSIONS:Integrating CVD and HIV care is feasible in LMICs, although methodology for reporting feasibility is inconsistent. Assessing feasibility based on settings and integration goals will provide a unique perspective of the implementation landscape in LMICs. There is a need for consistency in measures in order to accurately assess the feasibility of integrated CVD-HIV care in LMICs.
