Neural correlates of perceived physical and mental fatigability in older adults: A pilot study.

This pilot work examined associations of brain grey matter volumes (GMV) with perceived fatigability in older adults to elucidate disablement mechanisms. A subsample (n = 29; age = 77.2 ± 5.

Racial and Ethnic Heterogeneity in the Association Between Total Cholesterol and Pediatric Obesity.

Total cholesterol (TC) directly correlates with overweight/obesity, but it remains unclear if this association varies by race and ethnicity. We assessed the association as well as the racial/ethnic heterogeneity in this relationship. Data on 63,863 children were assessed using electronic medical records between 2010 and 2011.

A Comparison of Teaching Modalities and Fidelity of Simulation Levels in Teaching Resuscitation Scenarios.

Introduction: The purpose of our study was to examine the ability of novices to learn selected aspects of Advanced Cardiac Life Support (ACLS) in training conditions that did not incorporate simulation compared to those that contained low- and high-fidelity simulation activities. We sought to determine at what level additional educational opportunities and simulation fidelity become superfluous with respect to learning outcomes.

Methods: Totally 39 medical students and physician assistant students were randomly assigned to 4 training conditions: control (lecture only), video-based didactic instruction, low-, and high-fidelity simulation activities.
