Endoscopic features differentiating non‐Helicobacter pylori Helicobacter‐induced gastric mucosa‐associated lymphoid tissue lymphoma with a nodular gastritis‐like appearance and H. pylori‐induced conventional nodular gastritis

open access: yesDigestive Endoscopy, EarlyView.
Objectives Conventional nodular gastritis has been known to be caused by Helicobacter pylori infection. Several cases of gastric mucosa‐associated lymphoid tissue (MALT) lymphoma with non‐H. pylori Helicobacters (NHPH) exhibit endoscopic findings resembling nodular gastritis.

Gastric microbiota‐specific signatures in adults with obesity and Helicobacter pylori‐negative gastritis

open access: yesEuropean Journal of Clinical Investigation, EarlyView.
Abstract Background The role of the gastric microbiome in the pathophysiology of gastritis beyond Helicobacter pylori (HP) infection is poorly understood and has remained unexplored in patients with obesity. The aim of this study was to analyse gastric mucosa‐associated microbiota in patients with obesity and nonatrophic chronic gastritis in the ...

PI3Kγ in Tumour Inflammation: Bridging Immune Response and Cancer Progression—A Mini‐Review

open access: yesImmunology, EarlyView.
Myeloid cell PI3Kγ can be activated by G Protein‐Coupled Receptors or Receptor Tyrosine Kinases. Once activated, PI3Kγ promotes integrin activation as well as Akt and mTOR activation, thereby promoting transcription of immune‐suppressive and pro‐angiogenic factors, such as Arginase, IL‐10, TGFβ and VEGF‐A.

Gastric Cancer Mortality in a High Incidence Area: Long-term follow-up of Helicobacter pylori-related Precancerous Lesions in the General Population [PDF]

open access: yes
BACKGROUND: Due to a lack of clear criteria for recognizing subjects at risk of progression to gastric cancer (GC), this cohort study seeks to identify predictors of GC death in a high-risk population. METHODS: During 2000-2001, 1011 randomly selected

Evaluating Malignant Potential of Gastric Adenomas: The Role of Endoscopic Features and Genetic Alterations

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background and Aim There is no “gold standard” treatment for gastric adenomas due to uncertainty about their malignant potential. We wanted to understand better the factors contributing to their transformation into malignant tumors by analyzing their long‐term development, including endoscopic observations and genetic abnormalities.
