Preoperative nutritional status, frailty, and postoperative delirium in patients undergoing pancreatic cancer surgery: a prospective observational study (opens in new tab)

Patients undergoing pancreatic cancer surgery are particularly vulnerable to nutritional impairment and physiological decline, both of which may increase susceptibility to POD.
