Focal ST-segment elevation without coronary occlusion: myocardial infarction with no obstructive coronary atherosclerosis associated with COVID-19-a case report.

Background: While it is understood that coronavirus disease 2019 (COVID-19) is primarily complicated by respiratory failure, more data are emerging on the cardiovascular complications of this disease. A subset of COVID-19 patients present with ST-elevations on electrocardiogram (ECG) yet normal coronary angiography, a presentation that can fit criteria for myocardial infarction with no obstructive coronary atherosclerosis (MINOCA). There is little known about non-coronary myocardial injury observed in patients with COVID-19, and we present a case that should encourage further conversation and study of this clinical challenge.

Effects of left ventricular assist device on pulmonary functions and pulmonary hemodynamics: A meta-analysis. waqasullah.dr@gmail.com.

Background: Given current evidence, the effect of left ventricular assist device (LVAD) implantation on pulmonary function tests remains controversial.

Aim: To better understand the factors contributing to the changes seen on pulmonary function testing and the correlation with pulmonary hemodynamics after LVAD implantation.

Methods: Electronic databases were queried to identify relevant articles.

Interpretation and Impact of Real-World Clinical Data for the Practicing Clinician.

Real-world studies have become increasingly important in providing evidence of treatment effectiveness in clinical practice. While randomized clinical trials (RCTs) are the "gold standard" for evaluating the safety and efficacy of new therapeutic agents, necessarily strict inclusion and exclusion criteria mean that trial populations are often not representative of the patient populations encountered in clinical practice. Real-world studies may use information from electronic health and claims databases, which provide large datasets from diverse patient populations, and/or may be observational, collecting prospective or retrospective data over a long period of time.

Nerve and tendon injury with percutaneous fibular pinning: a cadaveric study.

Objective: The purposes of this study were to measure the average distance from a percutaneous pin in each quadrant of the distal fibula to the sural nerve and nearest peroneal tendon, and define the safe zone for percutaneous pin placement as would be used during surgery.

Method: Ten fresh-frozen cadavers underwent percutaneous pin fixation into four quadrants of the distal fibula. The sural nerve and peroneal tendon were identified as they coursed around the lateral ankle.
