Conduction system pacing versus biventricular pacing in heart failure with reduced ejection fraction: A systematic review and meta-analysis of randomized controlled trials.

Conduction system pacing (CSP) has emerged as a promising alternative to biventricular pacing (BVP) in patients with heart failure with reduced ejection fraction (HFrEF) and ventricular dyssynchrony, but its benefits are uncertain. In this study, we aimed to evaluate clinical outcomes of CSP vs BVP for cardiac resynchronization in patients with HFrEF. PubMed, Scopus, and Cochrane databases were searched for randomized controlled trials comparing CSP to BVP for resynchronization therapy in patients with HFrEF.

Higher serum uric acid is associated with body fat, retinol-binding protein 4, and antioxidative status in Brazilian children.

Objective: The aim of this study was to evaluate the association of serum uric acid (SUA) with adiposity, adipokines, and anti- and oxidative markers in Brazilian children.

Methods: This was a cross-sectional investigation with 378 children ages 8 to 9 y in Viçosa, Minas Gerais, Brazil. Information on sociodemographic and lifestyle characteristics was obtained via questionnaires, and body fat was determined by dual energy x-ray absorptiometry.

The role of human milk banks in promoting maternal and infant health: a systematic review.

Aimed at strengthening breastfeeding policies, human milk banks (HMBs) play an important role in promoting, protecting and supporting this practice. The objective of this study was to undertake a systematic review to identify activities developed by HMBs that demonstrate their role in promoting maternal and infant health. Searches for relevant articles were performed in the following databases: PubMed, Virtual Health Library (BVS), and BVS Breastfeeding linked to the portal of the Brazilian Human Milk Bank Network.
