I Brazilian guideline on hypertension in dialysis of the Brazilian Society of Nephrology.

Hypertension in dialysis patients (HTND) has a high prevalence, affecting at least 80% or more of patients, and its management in the nephrology practice is heterogeneous and often empirical. Knowing how to define, understand the pathophysiology, diagnose, monitor and treat with lifestyle changes, and adjust antihypertensive drugs to achieve the recommended blood pressure (BP) target - to reduce morbidity and mortality - requires specific knowl-edge and approaches within the contexts of hemodialysis (HD) and peritoneal dialysis (PD). This document is the first guideline of the Brazilian Society of Nephrology, developed by the departments of Hypertension and Dialysis.

Preterm Birth and SARS-CoV-2: Does a Correlation Exist?

The emergence of the SARS-CoV-2 virus and its subsequent global pandemic have raised significant concerns regarding its impact on pregnancy outcomes. This review aims to summarize the emerging data on the risk of preterm delivery in pregnant women infected with SARS-CoV-2. A systematic search was conducted from March 2020 to December 2023 using PubMed and Web of Science, following PRISMA guidelines.

Cardiac Tumors Causing Sudden Cardiac Death: A State-of-the-Art Review in Pathology.

Cardiac tumors (CTs), although rare, can be a significant cause of sudden cardiac death (SCD), particularly when not diagnosed early. The tumors most associated with SCD include myxomas, fibromas, rhabdomyomas, and sarcomas, which can cause fatal arrhythmias, blood flow obstruction, or embolization. Myxomas, which often develop in the left atrium, can cause valvular obstruction or cerebral emboli, while malignant tumors, such as sarcomas, can infiltrate the myocardium or conduction system, causing serious arrhythmias.
