Role of a Chest X-ray Severity Score in a Multivariable Predictive Model for Mortality in Patients with COVID-19: A Single-Center, Retrospective Study.

Predicting the mortality risk of patients with Coronavirus Disease 2019 (COVID-19) can be valuable in allocating limited medical resources in the setting of outbreaks. This study assessed the role of a chest X-ray (CXR) scoring system in a multivariable model in predicting the mortality of COVID-19 patients by performing a single-center, retrospective, observational study including consecutive patients admitted with a confirmed diagnosis of COVID-19 and an initial CXR. The CXR severity score was calculated by three radiologists with 12 to 15 years of experience in thoracic imaging, based on the extent of lung involvement and density of lung opacities.

Renal recovery after acute kidney injury in a minority population of hospitalized COVID-19 patients: A retrospective cohort study.

This study aimed to characterize survivors of Coronavirus disease 2019 (COVID-19) infection and acute kidney injury (AKI) that recover their renal function or progress to acute kidney disease (AKD) on discharge; and determine factors associated with progression to AKD during hospital stay.One thousand seventy four patients with COVID-19 infection were followed up until discharge/death. The incidence of AKI was 59.

Empiric use of anticoagulation in hospitalized patients with COVID-19: a propensity score-matched study of risks and benefits.

Background: Hospitalized patients with COVID-19 demonstrate a higher risk of developing thromboembolism. Anticoagulation (AC) has been proposed for high-risk patients, even without confirmed thromboembolism. However, benefits and risks of AC are not well assessed due to insufficient clinical data.
