Acute renal failure, COVID-19 and deaths, worrying rates in intensive care units: a cross-sectional study.

Background: Acute kidney failure is a serious consequence of coronavirus disease 2019 (COVID-19).

Objectives: To identify the prevalence of COVID-19, kidney failure, frequency of death, and associated factors in patients receiving intensive care.

Design And Setting: Analytical cross-sectional study conducted in the intensive care unit (ICU) of a medium-sized philanthropic general hospital in center-west Minas Gerais.

Omeprazole use and risk of chronic kidney disease evolution.

Rationale, Aims And Objectives: In recent years, the use of proton pump inhibitors (PPI), especially omeprazole, has been associated with development of chronic kidney disease (CKD). These drugs are widely used worldwide. Although some studies have found an association between the use of PPI and the onset of acute renal failure and CKD.

Sickle cell disease: Hemostatic and inflammatory changes, and their interrelation.

Sickle cell disease, the most common genetic blood disorder in the world, has high clinical variability, negatively impacts quality of life and contributes to early mortality. Sickled erythrocytes cause blood flow obstruction, hemolysis, and several hemostatic changes that promote coagulation. These events, in turn, induce chronic inflammation, characterized by elevated plasma levels of pro-inflammatory markers, which aggravates the already unfavorable state of the circulatory system.
