DUPAN-2 was an effective surrogate biomarker for monitoring treatment response in patients with #PancreaticCancer who are carbohydrate antigen 19-9 nonexpressors, and normal levels were associated with improved outcomes. ja.ma/4xissRB
Research poster from JAMA Surgery: DUPAN-2 as a biomarker for 2,418 pancreatic cancer patients, particularly CA19-9 non-expressors. Survival curves & bar charts show DUPAN-2's correlation with overall survival for monitoring treatment.

Retromuscular mesh placement and intraperitoneal onlay mesh were associated with higher risk of reoperation for recurrence and bowel obstruction vs onlay placement after primary ventral hernia repair. ja.ma/4vzg4uJ
JAMA Surgery: Study on mesh placement & risk of reoperation/bowel obstruction after primary ventral hernia repair. 17,832 repairs (2014-2025) in Denmark. Compares Onlay, Retromuscular, Preperitoneal, IPOM. Graphs show cumulative reoperation & bowel obstruction rates over 10 years. Onlay & preperitoneal are preferable options.
