BACKGROUND:The prevalence of global health in graduate medical education in the United States (US) has soared over the past two decades. The majority of US internal medicine and pediatric residency programs now offer global health electives abroad. Despite the prevalence of global health electives among US graduate medical programs today, challenges exist that may impact the experience for visiting trainees and/or host institutions. Previous reviews have predominately focused on experiences of undergraduate medical students and have primarily described positive outcomes. OBJECTIVES/OBJECTIVE:The aim of this study was to summarize the overall impact of global health electives on US internal medicine, medicine-pediatric, and pediatric residents, paying specific attention to any negative themes reported in the literature. METHODS:An Ovid MEDLINE and Ovid EMBASE literature search was conducted to identify studies that evaluated the effects of global health electives on US internal medicine, medicine-pediatric, and pediatric residents. FINDINGS/RESULTS:Ten studies were included. Four positive themes emerged: (1) improvement of medical knowledge, physical examination, and procedural skills, (2) improvement in resourcefulness and cost-effectiveness, (3) improvement in cultural and interpersonal competence, and (4) professional and career development. Two negative themes were identified: (1) health risks and (2) safety risks. CONCLUSIONS:Global health electives provide a number of perceived benefits for US medical trainees; however, we importantly highlight health and safety concerns described while abroad. Global health educators should recognize the host of unique challenges experienced during a global health elective and investigate how to best mitigate these concerns. Incorporation of mandatory pre-, intra-, and post-elective training programs and establishment of universally adopted global health best practice guidelines may serve to address some the challenges visiting trainees encounter while abroad.

Aims:Pathologic evidence supports unique sex-specific mechanisms as precursors for acute cardiovascular (CV) events. Current evidence on long-term CV risk among women when compared with men based on measures of coronary artery calcium (CAC) remains incomplete. Methods and results:A total of 63 215 asymptomatic women and men were enrolled in the multicentre, CAC Consortium with median follow-up of 12.6 years. Pooled cohort equation (PCE) risk scores and risk factor data were collected with the Agatston score and other CAC measures (number of lesions and vessels, lesion size, volume, and plaque density). Cox proportional hazard models were employed to estimate CV mortality (n = 919). Sex interactions were calculated. Women and men had average PCE risk scores of 5.8% and 9.1% (P < 0.001). Within CAC subgroups, women had fewer calcified lesions (P < 0.0001) and vessels (P = 0.017), greater lesion size (P < 0.0001), and higher plaque density (P = 0.013) when compared with men. For women and men without CAC, long-term CV mortality was similar (P = 0.67), whereas detectable CAC was associated with 1.3-higher hazard for CV death among women when compared with men (P < 0001). Cardiovascular mortality was higher among women with more extensive, numerous, or larger CAC lesions. The relative hazard for cardiovascular disease (CVD) mortality for women and men was 8.2 vs. 5.1 for multivessel CAC, 8.6 vs. 5.9 for ≥5 CAC lesions, and 8.5 vs. 4.4 for a lesion size ≥15 mm3, respectively. Additional explorations revealed that women with larger sized and more numerous CAC lesions had 2.2-fold higher CVD mortality (P < 0.0001) as compared to men. Moreover, CAC density was not predictive of CV mortality in women (P = 0.51) but was for men (P < 0.001), when controlling for CAC volume and cardiac risk factors. Conclusion:Our overall findings support that measures beyond the Agatston score provide important clues to sex differences in atherosclerotic plaque and may further refine risk detection and focus preventive strategies of care.

CONTEXT:Treatment options for chronic hepatitis C virus (HCV) have improved in recent years. The burden of HCV in New York City (NYC) is high. Measuring treatment and cure among NYC residents with HCV infection will allow the NYC Department of Health and Mental Hygiene (DOHMH) to appropriately plan interventions, allocate resources, and identify disparities to combat the hepatitis C epidemic in NYC. OBJECTIVE:To validate algorithms designed to estimate treatment and cure of HCV using RNA test results reported through routine surveillance. DESIGN:Investigation by NYC DOHMH to determine the true treatment and cure status of HCV-infected individuals using chart review and HCV test data. Treatment and cure status as determined by investigation are compared with the status determined by the algorithms. SETTING:New York City health care facilities. PARTICIPANTS:A total of 250 individuals with HCV reported to the New York City Department of Health and Mental Hygiene (NYC DOHMH) prior to March 2016 randomly selected from 15 health care facilities. MAIN OUTCOME MEASURES:The sensitivity and specificity of the algorithms. RESULTS:Of 235 individuals successfully investigated, 161 (69%) initiated treatment and 96 (41%) achieved cure since the beginning of 2014. The treatment algorithm had a sensitivity of 93.2% (95% confidence interval [CI], 89.2%-97.1%) and a specificity of 83.8% (95% CI, 75.3%-92.2%). The cure algorithm had a sensitivity of 93.8% (95% CI, 88.9%-98.6%) and a specificity of 89.4% (95% CI, 83.5%-95.4%). Applying the algorithms to 68 088 individuals with HCV reported to DOHMH between July 1, 2014, and December 31, 2016, 28 392 (41.7%) received treatment and 16 921 (24.9%) were cured. CONCLUSIONS:The algorithms developed by DOHMH are able to accurately identify HCV treatment and cure using only routinely reported surveillance data. Such algorithms can be used to measure treatment and cure jurisdiction-wide and will be vital for monitoring and addressing HCV. NYC DOHMH will apply these algorithms to surveillance data to monitor treatment and cure rates at city-wide and programmatic levels, and use the algorithms to measure progress towards defined treatment and cure targets for the city.

BACKGROUND:Circulating free DNA sequencing (cfDNA-Seq) can portray cancer genome landscapes, but highly sensitive and specific technologies are necessary to accurately detect mutations with often low variant frequencies. METHODS:We developed a customizable hybrid-capture cfDNA-Seq technology using off-the-shelf molecular barcodes and a novel duplex DNA molecule identification tool for enhanced error correction. RESULTS:mutations originating from clonal hematopoiesis. Furthermore, cfDNA-Seq off-target read analysis allowed simultaneous genome-wide copy number profile reconstruction in 20 of 28 cases. Copy number profiles were validated by low-coverage whole-genome sequencing. CONCLUSIONS:This error-corrected, ultradeep cfDNA-Seq technology with a customizable target region and publicly available bioinformatics tools enables broad insights into cancer genomes and evolution. CLINICALTRIALSGOV IDENTIFIER/UNASSIGNED:NCT02112357.

Introduction: Cardiovascular risk factors associated with the development of systemic atherosclerosis relate in part to socioeconomic environment, but the relationship between the socioeconomic environment and vascular disease is uncertain. Hypothesis: A poorer socioeconomic environment is associated with increased prevalence of lower extremity peripheral artery disease (PAD) and carotid artery stenosis (CAS) even after adjusting for traditional cardiovascular risk factors.
Method(s): Retrospective analysis of ~3 million participants in the cross-sectional pay-for-screening Life Line Screening survey in 2003-2008 at 20,000 sites across all 50 states. Socioeconomic environment scores (SES) were constructed from US Census data. Prevalence of PAD (ABI <0.9) and CAS (stenosis >=50% on carotid ultrasound) were compared by SES quartile within sex and race subgroups using the Cochran Armitage trend test. Logistic regression models were used to assess strength of association and adjusted for demographics, cardiovascular risk factors, and state of residence.
Result(s): Of 3,696,778 participants, 2,851,470 white and black participants were included for PAD and 2,981,111 for CAS; mean age was 63.7+/-10.4 years and 63.8% were female. The prevalence of PAD and CAS was greater with lower SES quartiles in all race and sex subgroups (Figure 1; p<0.0001 for trend for each comparison). The associations between SES and both PAD and CAS remained significant after multivariable adjustment including traditional cardiovascular risk factors and state of residence (Figure 2).
Conclusion(s): A poorer socioeconomic environment is associated with a higher prevalence of PAD and CAS and may be an independent risk factor beyond traditional cardiovascular risk factors. Figures: (Figure Presented)

In the version of this Letter originally published, in Fig. 2d, in the third graph, the label for the y axis was incorrect as 'TNF-α (pg ml^-1)'; it should have read 'IL-1β (pg ml^-1)'. This has now been corrected.

With the opioid overdose mortality rates rising nationally, The New York City Department of Health and Mental Hygiene (NYC DOHMH) has worked to expand overdose rescue training (ORT) and naloxone distribution. This study sought to determine rates of overdose witnessing and naloxone use among overdose rescue-trained visitors to the NYC jails on Rikers Island. We conducted a six-month prospective study of visitors to NYC jails on Rikers Island who received ORT. We collected baseline characteristics of study participants, characteristics of overdose events, and responses to witnessed overdose events, including whether the victim was the incarcerated individual the participant was visiting on the day of training. Bivariate analyses compared baseline characteristics of participants who witnessed overdoses to those who did not, and of participants who used naloxone to those who did not. Overall, we enrolled 283 participants visiting NYC's Rikers Island jails into the study. Six months after enrollment, we reached 226 participants for follow-up by phone. 40 participants witnessed 70 overdose events, and 28 participants reported using naloxone. Of the 70 overdose events, three victims were the incarcerated individuals visited on the day of training; nine additional victims were recently released from jail and/or prison. Visitors to persons incarcerated at Rikers Island witness overdose events and are able to perform overdose rescues with naloxone. This intervention reaches a population that includes not only those recently released, but also other people who experienced overdose.

Psoriasis is a chronic inflammatory disease with both a physical and psychosocial burden. To offer strategies for dermatology residents to assess and manage psychosocial aspects of psoriasis, a PubMed search of articles indexed for MEDLINE was performed using the following terms: psoriasis, depression, anxiety, work productivity, sexual functioning, and interpersonal relationships. Selected articles covered the prevalence, assessment, and management of each of the psychosocial domains of psoriasis. Depression is a common comorbidity in psoriasis patients, and the psychosocial burden of psoriasis is immense. Dermatology providers play a vital role in assessing and managing the psychosocial aspects of the disease along with medical management.
