Extracellular vesicles (EVs) are tiny particles secreted by cells that mediate intercellular communication and regulate immune responses. By carrying microRNAs, proteins, and lipids, EVs spread cellular senescence and promote the senescence-associated secretory phenotype (SASP), creating a cycle of "senescence-inflammation-dysfunction". In a recent review, researchers from China elaborate how EVs mediate cellular senescence in multiple chronic lung diseases. It also discusses the advances, existing challenges, and translational prospects of EV-based therapies for these aging-related pulmonary diseases.

A nationwide survey of 130 Chinese pancreatic surgeons finds that perioperative nutrition management for pancreatoduodenectomy has improved substantially since 2020. Preoperative nutritional assessment rose from 62.5% to 82.3% and dietitian involvement from 49.0% to 70.0%. However, total parenteral nutrition on the first postoperative day remained high at 52.3%, while early oral feeding was only 16.2%.
