Postmortem Biopsies of the Lung, Heart, Liver, and Spleen of COVID-19 Patients.

Objective We aimed to evaluate histopathologic alterations in the lung, heart, liver, and spleen of coronavirus disease 2019 (COVID-19) decedents through postmortem core needle biopsies. Materials and methods Patients who died of reverse transcription-polymerase chain reaction-proven COVID-19 were included in this postmortem case series. Postmortem percutaneous ultrasound-guided biopsies of the lungs, heart, liver, and spleen were performed using 14- and 16-gauge needles.

Brachial Artery Wall Stiffness Assessment by Shear Wave Elastography: A Promising New Diagnostic Tool for Endothelial Dysfunction Detection.

Objectives: This study was designed to measure the changes in brachial artery wall stiffness by shear wave elastography (SWE) and evaluate the accuracy of SWE changes for detection of endothelial dysfunction.

Methods: Sixty-five consecutive participants (19 patients with atherosclerosis proven by coronary angiography, 16 healthy young adults, 15 patients with cardiovascular risk factors, and 15 healthy older adults between 50 and 60 years) were prospectively included in this study. They were examined in the same week by SWE, and flow-mediated dilatation was evaluated for each patient.
