Global burden of heart failure in children and adolescents from 1990 to 2019: an analysis from the Global Burden of Disease Study 2019.

Background: Heart failure (HF) significantly impacts the cardiovascular health of children and adolescents. This study aims to assess epidemiologic trends in HF across sex, age, region, and time period.

Methods: The number and age-standardized rate (ASR) of prevalence and years lived with disability (YLDs) were derived from the Global Burden of Disease Study 2019.

Effect of perioperative analgesia on immunity in lung cancer.

COX inhibitors are frequently used for pain management during the perioperative period and may influence tumor progression and the tumor microenvironment by modulating inflammation and immune responses. This study investigates the effects of COX inhibitors on tumor growth and the immune microenvironment. In vivo experiments demonstrate that COX inhibitors can reduce tumor cell growth, elevate PD-L1 expression on tumor cells, and enhance the proportion of myeloid cells within the tumor immune microenvironment.

Membranes of Polymer of Intrinsic Microporosity PIM-1 for Gas Separation: Modification Strategies and Meta-Analysis.

Polymers of intrinsic microporosity (PIMs) have received considerable attention for making high-performance membranes for carbon dioxide separation over the last two decades, owing to their highly permeable porous structures. However, challenges regarding its relatively low selectivity, physical aging, and plasticisation impede relevant industrial adoptions for gas separation. To address these issues, several strategies including chain modification, post-modification, blending with other polymers, and the addition of fillers, have been developed and explored.
