Benefit of Linked‐Color Imaging in Artificial Intelligence‐Assisted Diagnosis of Early Gastric Cancer: A Pilot Study With Propensity Score Adjustment

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Background and Aims Artificial intelligence (AI)‐assisted endoscopy represents a promising approach for lesion detection, yet frequent false‐positive detections impair clinical utility by disrupting examinations and diminishing physician confidence.

Significance of serological atrophic gastritis on proton pump inhibitor prescriptions and referrals to gastroscopy in the general population

JGH Open
Background and Aim We aimed to investigate whether individuals with low pepsinogen I levels differed from those with normal pepsinogen I levels in terms of proton pump inhibitors (PPIs) use, referral to gastroscopy, and findings on gastroscopy.

Submucosal Invasion and Ulceration in Early Gastric Cancer Affect Mucosal Impedance

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives To investigate early changes in gastric cancers that are difficult to evaluate using endoscopic imaging through the assessment of mucosal impedance (MI) in endoscopic submucosal dissection (ESD) specimens. Methods In this single‐center prospective cohort study, we included patients who underwent ESD for early gastric cancer (EGC ...

Synchronous and Metachronous Multiple Gastric Epithelial Neoplasms Detected During Index Evaluation and Post‐Endoscopic Submucosal Dissection Surveillance: A Descriptive Comparison

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives We compared synchronous and metachronous gastric tumors detected during index evaluation and surveillance after endoscopic submucosal dissection (ESD), focusing on Kimura‐Takemoto O‐3 atrophy. Helicobacter pylori eradication history and the neutrophil‐to‐lymphocyte ratio (NLR) were exploratory.

Helicobacter pylori Outer Membrane Vesicles Engage TLR2 Through NapA to Promote Epithelial Association and Inflammatory Signalling

Journal of Extracellular Vesicles, Volume 15, Issue 10, October 2026.
ABSTRACT Helicobacter pylori infection is characterized by chronic gastric inflammation driven by persistent activation of innate immune signalling pathways. Outer membrane vesicles (OMVs) released by H. pylori are important mediators of host–pathogen interactions. Although several mechanisms of OMV internalization have been described, how specific OMV‐
