Assessment of Cardiac, Vascular, and Pulmonary Pathobiology In Vivo During Acute COVID-19.

Background Acute COVID-19-related myocardial, pulmonary, and vascular pathology and how these relate to each other remain unclear. To our knowledge, no studies have used complementary imaging techniques, including molecular imaging, to elucidate this. We used multimodality imaging and biochemical sampling in vivo to identify the pathobiology of acute COVID-19.

A multifaceted intervention to reduce rates of catheter-associated urinary tract infections in a resource-limited setting.

Background: Health care-associated infections such as catheter-associated urinary tract infections (CAUTIs) are prevalent in resource-limited settings. This study was carried out to determine whether a multifaceted intervention targeting health care personnel would reduce CAUTI rates in a public hospital located in a resource-limited setting.

Methods: A one group, pretest-posttest study was carried out from March to July 2012 in a public district hospital in Nairobi, Kenya.
