Introduction: Eye emergencies make up nearly 3% of US emergency department (ED) visits. While emergency physicians (EP) should diagnose and treat these ophthalmologic emergencies, many trainees report limited ocular exposure and insufficient training throughout their residency to confidently conduct a thorough slit-lamp exam.

Methods: We created an interdisciplinary, simulation-based mastery learning (SBML) curriculum to teach emergency attending physicians how to operate the slit lamp with multimodal learning methodology at a tertiary academic center.

Despite physical activity being a key component of maintaining health and preventing disease progression, medical schools are not providing sufficient education on physical activity to medical students. As a result, medical students and new residents express a lack of confidence and knowledge when engaging in exercise prescription conversations with patients. A group of 20 first-year medical students at Sidney Kimmel Medical College (SKMC) attended a selective course on exercise prescription and the American College of Sports Medicine (ACSM) physical activity guidelines.

The present study is a follow-up of a prior study examining a broad range of longitudinal predictors of dimensional positive mental health (PMH) and negative mental health (NMH), using cross-cultural data from the Bochum Optimism and Mental Health (BOOM) study. The present study sought to expand prior findings on positive mental health predictors to a longer longitudinal timeframe. The analysis, specifically, tests our prior model using a third time point, The following positive constructs were examined in relation to later positive mental health: resilience, social support, social rhythm, family affluence, physical health and expectations for fertility.

International Medical Graduate (IMG) physicians applying to residency training programs in a country different from where they completed medical school, bring beneficial diversity to a training program, but also face significant challenges matching into an Accreditation Council for Graduate Medical Education (ACGME)-accredited residency program. Despite the growing number of IMG applications in Emergency Medicine (EM), there is a paucity of targeted recommendations for IMG applicants. As a result, the Council of Residency Directors (CORD) Advising Students Committee in EM (ASC-EM) created a dedicated IMG Advising Team to create a set of evidence-based advising recommendations based on longitudinal data from the National Residency Match Program (NRMP) and information collected from EM program directors and clerkship directors.
