Veno-venous extracorporeal membrane oxygenation (VV ECMO) cannula malposition identified with point-of-care ultrasound.

Background: Point-of-care ultrasound (POCUS) has become a mainstay in the evaluation of critically ill patients in the intensive care unit (ICU). ECMO patients are susceptible to complications during prolonged ICU stay, including cannula malposition, which has deleterious consequences. Although the literature surrounding utility of ultrasound on ECMO patients is expansive, direct comparison between radiographic imaging versus ultrasound for identification of cannula malposition is lacking.

Implementing a 3 year, longitudinal point of care ultrasound curriculum in an internal medicine residency program.

Purpose: Point-of-care ultrasound (POCUS) is highly utilized in the critical care setting. There is also growing evidence supporting use of POCUS by internal medicine (IM) physicians as an extension of traditional physical diagnostic skills. As part of the newly formed curriculum at our residency program, we performed pre and post curriculum assessment of the residents' ability to acquire focused cardiac, lung, pleural, abdominal and vascular images.

Glucose tolerance status associates with improvements in cognitive function following high-intensity exercise in adults with obesity.

Purpose: Obesity, insulin resistance (IR), and proinflammatory cytokines associate with cognitive decline. Numerous studies document cognitive benefits of acute exercise bouts in lean individuals. However, how co-morbidities such as obesity and IR influence cognitive changes induced by acute exercise is unclear.

A meal enriched in saturated fat acutely impairs cognitive performance in obese men.

Background: Diets chronically high in saturated fat (SFA) associate with obesity and insulin resistance (IR), which in turn associate with cognitive decline and dementia. However, understanding how acute SFA consumption influences cognition is less clear despite short-term SFA-enriched diets inducing whole-body IR. We examined how consuming meals enriched with SFA or monounsaturated fat (MUFA) acutely influence cognitive function in lean and obese men.
