Time-related aortic inflammatory response, as assessed with F-FDG PET/CT, in patients hospitalized with severely or critical COVID-19: the COVAIR study.

Aim: Arterial involvement has been implicated in the coronavirus disease of 2019 (COVID-19). Fluorine 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) imaging is a valuable tool for the assessment of aortic inflammation and is a predictor of outcome. We sought to prospectively assess the presence of aortic inflammation and its time-dependent trend in patients with COVID-19.

Coexisting morbidity burden in elderly hospitalized patients with and without heart failure.

Introduction: Aging, cardiovascular disease (CVD), and heart failure (HF) increase the coexisting morbidity (CM) burden. This study compared the contribution of HF with this increase in elderly patients hospitalized for CVD by comparing patients with and without HF.

Methods: Consecutive patients aged >65 years, hospitalized with CVD, were included (104 with and 100 without HF).

Anomalous muscle causing ulnar nerve compression at Guyon's canal.

We report a rare anatomical variation of an anomalous supernumerary muscle in a male cadaver. It was crossing Guyon's canal, superficial to the ulnar nerve and ulnar artery, and inserted into the aponeurosis of the little finger. This muscle could potentially cause entrapment of the ulnar nerve in Guyon's canal.

Impact of dopamine infusion on renal function in hospitalized heart failure patients: results of the Dopamine in Acute Decompensated Heart Failure (DAD-HF) Trial.

Background: Worsening renal function (WRF) and hypokalemia related to diuretic use for acute decompensated heart failure (ADHF) are common and associated with poor prognosis. Low-dose dopamine infusion improves renal perfusion; its effect on diuresis or renal function specifically in ADHF is not known.

Methods And Results: Sixty consecutive ADHF patients (age 75.
