Intra-aortic balloon pumps (IABPs) are commonly used circulatory support devices. Mesenteric ischemia is a serious and poorly studied complication of IABP use. Here, we examine six cases of mesenteric ischemia associated with IABPs from a single urban academic medical center.

A growing cohort of studies has utilized message experiments to examine how different approaches for communicating scientific uncertainty impact public perceptions. Extending this program, we examine the effects of communicating different levels of uncertainty on public perceptions of advancements in HIV/AIDS research.

Several studies have suggested that MMAE improves the cost efficacy of cSDH treatment. However, further comprehensive analyses of the outcomes and healthcare costs of MMAE are necessary.

However, factors that promote sedentary lifestyle such as occupational obligations (desk-based work) or underlying health comorbidities can limit adherence to exercise regimes. Considering the current trends in physical inactivity, development of alternate strategies to replicate or mimic the beneficial adaptations associated with regular exercise may become a highly sought after commodity.

The aim of this study was to investigate the effects of acute caffeine supplementation on cycling time to exhaustion and thermoregulation in the heat.
Methods: In a double-blind, randomised, cross-over trial, 12 healthy caffeine-habituated and unacclimatised males cycled to exhaustion in the heat (35 °C, 40% RH) at an intensity associated with the thermoneutral gas exchange threshold, on two separate occasions, 60 min after ingesting caffeine (5 mg/kg) or placebo (5 mg/kg).
