Incidence of bradycardia with the use of remdesivir for coronavirus disease of 2019 and risk factor analysis.

Background: Remdesivir is commonly used for inpatient treatment of coronavirus disease of 2019 (COVID-19) and may be associated with bradycardia. The objective is to investigate the incidence of bradycardia in patients with COVID-19 receiving remdesivir and evaluate potential risk factors associated with bradycardia.

Methods: This single-center, retrospective, cohort study evaluated the incidence of bradycardia during and up to 48 h after remdesivir administration in adults admitted to the medical center for treatment of COVID-19.

Autophagy inhibition induces AML cell death and enhances the efficacy of chemotherapy under hypoxia.

Outcomes of relapsed/refractory acute myeloid leukemia (AML) are poor, and strategies to improve outcomes are urgently needed. One important factor promoting relapse and chemoresistance is the ability of AML cells to thrive in vivo within an intrinsically hypoxic bone marrow microenvironment. Here we show that human AML cells exhibit enhanced autophagy, specifically mitophagy (i.

Individualised prediction of major bleeding in patients with atrial fibrillation treated with anticoagulation.

Background: Anticoagulation in atrial fibrillation (AF) increases the risk of major bleeding. No predictive model has hitherto provided estimates of the absolute risk for individual patients.

Aim: To predict the individual 1-year risk of major bleeding in patients with AF taking anticoagulants and evaluate the importance of individual risk factors.

Assay for the quantification of abemaciclib, its metabolites, and olaparib in human plasma by liquid chromatography-tandem mass spectrometry.

An isotope-dilution bioanalytical assay for abemaciclib and its metabolites in combination with olaparib was developed and validated in human plasma K2 EDTA. For the quantitative assay, human plasma samples (or human plasma QC samples) were spiked with internal standard solution before a simple protein precipitation with methanol. The extract was injected onto a liquid chromatography-tandem mass spectrometry (LC-MS/MS) instrument where it was chromatographically separated by a polar end-capped reversed phase column and guard using gradient elution with water and methanol both modified with 0.
