Type 2 diabetes (T2D) is a chronic disease characterized by long-term insulin resistance (IR) and pancreatic β-cell dysfunction. Conventional T2D medication ignores pancreatic β-cell damage. In this study, we designed an oral glucose-responsive nanoparticle for pancreatic β-cell regeneration and treatment of T2D. It was formed by carboxymethyl chitosan (CMC) grafted with 3-aminophenylboronic acid (APBA) as the shell and small-molecule citrus pectin (MCP) spheres encapsulating artemisinin (Art) connected by borate ester bonds. The prepared CMC-APBA wrapped Art-loaded MCP nanoparticles (CAM@Art) had therapeutic effects for the treatment of IR, antioxidant and promotion of pancreatic α-cell differentiation in vitro experiments. In addition, in vivo experiments showed that CAM@Art could reduce blood glucose, oxidative stress and inflammation levels and reverse IR in diabetic rats. Importantly, pancreatic β-cell regeneration was found in islets in vivo. Mechanistically, CAM@Art promotes pancreatic α-cell differentiation by promoting overexpression of the transcription factor Pax4 and ectopic expression of Arx. The results suggest that the present study provides a promising therapeutic strategy for the treatment of diabetic pancreatic β-cell dysfunction.

The effectiveness of a conservative approach in the management of groove pancreatitis.
Indian J Gastroenterol

Department of Gastroenterology, Christian Medical College, Vellore, 632 517, India.
Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.
Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.
Pancreas-guided C-shaped surgical procedure: a safer and more efficient procedure for laparoscopic left hemicolectomy in obese patients.

The surgical risk is higher for obese patients undergoing laparoscopic left hemicolectomy. To enhance the surgical safety and efficacy for obese patients, we have innovatively integrated the advantages of various surgical approaches to modify a pancreas-guided C-shaped surgical procedure. The safety and quality were assessed through a retrospective analysis.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Pancreatic ductal adenocarcinoma during pregnancy is extremely rare. Overall, including our case, only 19 cases confirmed antepartum have been reported to date. We report the case of a 37 year-old woman at 24 weeks of pregnancy in whom a pancreatic adenocarcinoma was identified during investigation of a suspected acute pancreatitis.

Rev Gastroenterol Peru
January 2025
Division of Gastroenterology, Department of Internal Medicine, Virginia Tech Carilion Clinic, Roanoke, Virginia, USA.
Objectives: Pancreatic duct leaks can cause ascites, and fluid amylase can be used as a marker to suggest pancreatic duct leak; however, there is no reference parameter or cutoff value for diagnosis. We assessed whether a novel ratio of ascitic fluid to serum amylase can reliably predict pancreatic leaks and need for endoscopic retrograde cholangiopancreatography (ERCP).
Materials And Methods: Patients who had fluid amylase from ascitic fluid and serum amylase within one week of confirmed pancreatic leaks via ERCP were included along with appropriate medical and surgical controls.
