Use of iPads to Decrease Faculty Workload.

Background: Multiple faculty were present during a simulation for competency assessments of students, thus creating an increased workload and fatigue. Faculty used technology to reduce the workload and maintain interrater reliability, at little to no cost.

Method: The use of high-fidelity simulators, tablet computers, and a university video platform were used to record student competency assessments.

Effect of aging on cardiac function during cold stress in humans.

To determine whether skin surface cooling increases left ventricular preload and contractility to a greater extent in older compared with young adults we studied 11 young (28 +/- 2 yr; means +/- SE) and 11 older (64 +/- 3 yr) adults during normothermia (35 degrees C water perfused through a tube-lined suit) and cooling (15 degrees C water perfused for 20 min) using standard and tissue Doppler echocardiography. Cooling significantly decreased skin surface temperature in young (Delta2.8 +/- 0.

Aging affects the cardiovascular responses to cold stress in humans.

Cardiovascular-related mortality peaks during cold winter months, particularly in older adults. Acute physiological responses, such as increases in blood pressure, in response to cold exposure may contribute to these associations. To determine whether the blood pressure-raising effect (pressor response) of non-internal body temperature-reducing cold stress is greater with age, we measured physiological responses to 20 min of superficial skin cooling, via water-perfused suit, in 12 younger [25 +/- 1 (SE) yr old] and 12 older (65 +/- 2 yr old) adults.
