Single‐cell RNA sequencing revealed the T‐cell heterogeneity and exhaustion subsets of Helicobacter pylori‐induced gastritis‐to‐cancer transformation

open access: yesVIEW, EarlyView.
H. pylori infection is a major cause of stomach cancer, but its effect on immune cells in tumors is unclear. Using single‐cell sequencing, we mapped the stomach tumor environment and discovered a specific exhausted T‐cell subtype, marked by the FYB1 gene, that is abundant in H. pylori‐positive tumors and linked to patient prognosis. Our findings reveal

The OLGIMA system for gastric cancer risk assessment. A useful method based on the histological Sydney consensus

open access: yesHistopathology, EarlyView.
The new OLGIMA method for histological gastric cancer risk assessment is based on the severity of glandular atrophy and intestinal metaplasia, in both antrum and corpus, according to the Updated Sydney classification. The highest score of either atrophy or intestinal metaplasia from each location will be used for the final OLGIMA stage.

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

open access: yesJournal 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 ...

Olmesartan‐induced gastritis with no lower gastrointestinal symptoms: A case report

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
Abstract A 74‐year‐old man with decreased appetite, weight, and heartburn was referred to our hospital. His medications included olmesartan. Esophagogastroduodenoscopy (EGD) revealed antral‐dominant erosive gastritis and nodular mucosa. A gastric biopsy revealed inflammatory cell infiltration.

Visibility Evaluation of Fundic Gland Polyp Associated With Proton Pump Inhibitor in Texture and Color Enhancement Imaging

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives A ‘gray color sign’ (GCS) is a new endoscopic feature of fundic gland polyp associated with proton pump inhibitor (PPI‐FGP). Here, we compare the ability of texture and color enhancement imaging (TXI) to white light imaging (WLI) with regard to the detection of GCS. Methods In this prospective study, 19 consecutive patients with PPI‐
