The gastric mucosal calcinosis is a benign condition corresponding to calcium deposits in the gastric mucosa. A 39-year-old women, with an history of transplantation, transplant rejection and hemodialysis, treated with corticosteroids and calcium/phosphoremic supplements, had chronic diarrhea. Gastroduodenal fibroscopy found an atypical atrophic gastritis appearance with small focal whitish deposits in the gastric mucosa. Histological examination revealed brown and gray-bluish crystalline deposits in superficial chorion, stained by Von Kossa, leading to a diagnosis of gastric mucosal calcinosis. This lesion can be categorized as systemic, dystrophic, iatrogenic and idiopathic. In our observation, gastric mucosal calcinosis was probably mixed, linked to renal disorders, and mainly to exogenous phosphocalcic drug intakes. The gastric mucosal calcinosis is commonly found in kidney transplant patients reaching a frequency of 15 to 29%.

Division of Nutritional Sciences, University of Illinois Urbana-Champaign, Urbana, IL, 61801, USA.
The gastrointestinal (GI) microbiota plays a crucial role in host health and disease in dogs, but the knowledge regarding the mucosal associated microbiota along the GI tract is limited in dogs. Therefore, the objective of this study was to characterize the phylogeny and predicted functional capacity of microbiota residing on the gut mucosa across five GI regions of healthy young adult and geriatric dogs fed different diets. Twelve weanling (8 weeks old) and 12 senior (11.

Reduced gastric mucosal nerve density in functional dyspepsia: clinical significance and functional correlation.
Am J Gastroenterol
January 2025
Department of Anatomy and Cell Biology.
Background: This study aimed to quantitatively examine gastric mucosal nerve density (GMND) in patients with functional dyspepsia (FD) and analyzed its clinical correlation.
Methods: We prospectively enrolled 35 patients with FD and 16 age-and gender-matched healthy controls for comparison of GMND on endoscopic biopsy, scores of Gastroparesis Cardinal Symptom Index (GCSI), and gastric emptying scintigraphy (GES).
Results: Patients with FD had lower GMND than the control subjects in gastric antrum, body, and fundus.
Identification and Validation of Epithelial Cell Centre Regulatory Transcription Factors in the Gastric Cancer Microenvironment.
Int J Gen Med
December 2024
Department of Pathology, The First Affiliated Hospital of Kunming Medical University, Kunming, Yun Nan, People's Republic of China.
Purpose: To identify the epithelial cell centre regulatory transcription factors in the gastric cancer (GC) microenvironment and provide a new strategy for the diagnosis and treatment of GC.
Methods: The GC single-cell dataset was downloaded from the Gene Expression Omnibus (GEO) database. The regulatory mechanisms of transcription factors in both pan-cancer and GC microenvironments were analysed using the Cancer Genome Atlas (TGCA) database.
Randomized clinical trial: the effects of mirtazapine in functional dyspepsia patients.

Center of Health Management, Qilu Hospital of Shandong University, 107 Wenhuaxi Road, Jinan, Shandong 250012, China.
Background: Functional dyspepsia (FD) is one of the most common gastrointestinal disorders worldwide. Currently, anti-gastric drugs, gastric acid inhibitors, prokinetic drugs, and mucosal protective drugs are widely used in FD patients, however, only a small proportion of patients benefit from these drugs. Studies reported mirtazapine may improve symptoms of FD patients but the efficacy and safety of mirtazapine in the treatment of FD is unclear.
