D-dimer levels is associated with severe COVID-19 infections: A meta-analysis.

Objective: The ongoing pandemic of COVID-19 caused by the novel coronavirus Syndrome-Coronavirus-2 (SARS-CoV-2) is an emerging, rapidly evolving situation. Excluded typical manifestation of pneumonia and acute respiratory symptoms, COVID-19 patients also have abnormal D-dimer concentration in the serum, but the results are controversial.

Method: A meta-analysis first aims to explored the connection between D-dimer concentration and COVID-19 patients.

Association of Ang-2, vWF, and EVLWI with risk of mortality in sepsis patients with concomitant ARDS: A retrospective study.

Background/purpose: This study aimed to determine the potential effects of angiopoietin-2 (Ang-2), von Willebrand factor (vWF), and extravascular lung water index (EVLWI) on the risk of mortality in sepsis patients with concomitant acute respiratory distress syndrome (ARDS).

Methods: This retrospective study recruited 41 sepsis patients with concomitant ARDS from January 2015 to June 2018. Data of Ang-2 and vWF levels, EVLWI, and sequential organ failure assessment scores were collected at 0, 24, and 48 h after admission to the hospital.
