Studies find more patients admitted to hospitals with cardiac conditions in winter months

Researchers found a significant increase in hospitalizations for aortic dissection and ST-Elevation Myocardial Infarctions (STEMI) during winter months. The studies, presented at the SCAI 2018 Scientific Sessions, used the Nationwide Inpatient Sample database to analyze seasonal variations in cardiac-related hospitalizations.

A simple method etches patterns at the atomic scale

Researchers at Penn State have developed a chemical-free method for etching nanoscale features on silicon wafers. The technique, called tribochemical reaction, uses a scanning probe microscope to remove single layers of atoms from the surface without damaging underlying layers.

New study shows length of hospital stay impacts outcomes after TAVR procedure

A new study has found that patients who undergo TAVR procedure and stay in the hospital for more than 72 hours may be at risk of negative short and long-term outcomes. The study identified independent predictors of both early and delayed discharge, with delayed discharge associated with worse one-year outcomes.

First-of-its-kind study associates obesity with poorer stroke outcomes in non-white patients

A recent study found that obesity contributes to poorer outcomes in non-white patients who have hemorrhagic strokes, with African-Americans being particularly vulnerable. The research highlights the need for targeted interventions to address nutritional needs and reduce the burden of obesity on recovery following stroke.
