Practice Guidelines for the Diagnosis and Treatment of Subepithelial Lesion Observed in Upper Gastrointestinal Endoscopy

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Subepithelial lesions (SELs) of the upper gastrointestinal tract are commonly detected during endoscopic examinations and encompass a broad spectrum of benign, potentially malignant, and malignant tumors. While most SELs are asymptomatic and incidentally found, accurate diagnosis remains challenging due to their subepithelial location ...

Gut Microbial Variations Associated With Proton Pump Inhibitor Use in the Boston Puerto Rican Health Study

Pharmacology Research &Perspectives, Volume 14, Issue 1, February 2026.
ABSTRACT Proton pump inhibitors (PPI), used to treat gastrointestinal disorders, are associated with alterations in the gut microbiome. However, this is understudied in Puerto Ricans who have unique lifestyle characteristics. Puerto Ricans, including participants of the Boston‐Puerto Rican Health Study (BPRHS), report high PPI use.

Controversies in NEN: An ENETS position statement on the endoscopic management of localised gastric, duodenal and rectal neuroendocrine neoplasms

Journal of Neuroendocrinology, Volume 37, Issue 12, December 2025.
Abstract Gastric, duodenal and rectal neuroendocrine tumours (NETs) are increasingly detected due to advances in endoscopic imaging. While international guidelines provide criteria for endoscopic management, several aspects remain controversial due to limited high‐quality evidence.

Controversies in NEN: An ENETS position statement on nutritional support in neuroendocrine neoplasms

Journal of Neuroendocrinology, Volume 37, Issue 12, December 2025.
Abstract Neuroendocrine neoplasms (NEN) themselves and also their treatment may cause malnutrition, inducing changes in physiological behaviour and eventually leading to increased rates of morbidity and mortality. Malnutrition is a common, under‐recognised and under‐treated condition in patients with NEN, and there are limited data available on the ...

Association of Omeprazole‐Related Myopathy With Drug–Drug and Drug–Gene Interactions Involving CYP2C19 and CYP3A4: A Nested Case–Control Study

Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, Volume 45, Issue 10, Page 654-666, October 2025.
ABSTRACT Background Omeprazole, a widely used proton pump inhibitor, has been associated with rare but serious adverse events such as myopathy. Previous research suggests that concurrent use of omeprazole with fluconazole, a potent cytochrome P450 (CYP) 2C19/3A4 inhibitor, may increase the risk of myopathy.

Step‐by‐Step Approach to the Incidental Diagnosis of Type I Gastric Neuroendocrine Tumors: Practical Insights

JGH Open, Volume 9, Issue 9, September 2025.
ABSTRACT Objective The incidental diagnosis of type I gastric neuroendocrine tumors (gNETs) has become increasingly frequent in clinical practice, largely due to the widespread use of upper gastrointestinal endoscopy and improved recognition of these lesions.

Differences in Endoscopic Features of Gastric Neuroendocrine Tumor and Neuroendocrine Carcinoma From a Clinicopathological Perspective

JGH Open, Volume 9, Issue 9, September 2025.
ABSTRACT Gastric neuroendocrine neoplasms are a rare type of stomach cancer, classified into well‐differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Gastric NETs (G‐NETs) originate from endocrine progenitor cells in the basal layer of the mucosa, primarily in the setting of chronic atrophic gastritis,
