Impact of Ghrelin‐Depleting Gastrectomy on Long‐Term Endocrine and Metabolic Health With a Focus on Skeletal Muscle and Bone Mineral Content

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study investigates the long‐term endocrine and metabolic consequences of ghrelin‐depleted gastrectomy, with a focus on skeletal muscle mass and bone mineral content. Sustained reductions in serum desacyl‐ghrelin were linked to lower IGF‐1 levels, resulting in significant loss of muscle and bone.

Long‐Term Particulate Matter Exposure May Increase Risk of Chronic Rhinosinusitis WIth Nasal Polyposis: Results from an Exposure‐Matched Study

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Particulate matter ⩽2.5 µm in diameter (PM2.5) and its role in chronic rhinosinusitis (CRS) pathogenesis have gained heightened attention. We previously demonstrated that PM2.5 exposure may bias the nasal mucosa in CRS toward a Type 2 inflammatory pathway.
