Ministry of Higher Education, Mataria Technical College, Cairo, 11718, Egypt.
The current work introduces the hybrid ensemble framework for the detection and segmentation of colorectal cancer. This framework will incorporate both supervised classification and unsupervised clustering methods to present more understandable and accurate diagnostic results. The method entails several steps with CNN models: ADa-22 and AD-22, transformer networks, and an SVM classifier, all inbuilt.

To investigate the clinicopathological features, diagnosis, genetic alterations, and biological behaviors of hamartomatous inverted hyperplastic polyp (HIHP) in the gastrointestinal tract. The clinical, sonographic, endoscopic and pathologic data of 10 HIHP cases diagnosed at the First Affiliated Hospital of Air Force Medical University, Xi'an, China from January 2013 to March 2024 were collected. Their clinicopathological features and histological morphology were analyzed.

Autoimmune gastritis (AIG) is a chronic inflammatory condition characterized by immune-mediated destruction of gastric parietal cells, leading to oxyntic atrophy, achlorhydria, and hypergastrinemia. While AIG was historically linked to gastric adenocarcinoma and type I neuroendocrine tumors (NETs), recent evidence suggests the risk of adenocarcinoma in AIG is lower than previously believed, particularly in Helicobacter pylori (H. pylori)-negative patients.

Introduction: The current understanding of colorectal carcinogenesis is based on the adenoma-carcinoma sequence, where genetics, intestinal microbiota changes and local immunity shifts seem to play the key roles. Despite the emerging evidence of dysbiotic intestinal state and immune-cell infiltration changes in patients with colorectal adenocarcinoma, early and advanced adenoma as precursors of colorectal cancer, and carcinoma as the following progression, are rather less studied. The newly colon-site adapted AI-based analysis of immune infiltrates is able to predict long-term outcomes of colon carcinoma.

Background: Invasive bacterial biofilms are implicated in colorectal cancer. However, their prevalence on histologically normal tissues and polyps is not well established, and risk factors of biofilms have not been previously investigated. Here we evaluated potential procedural and demographic risk factors associated with biofilm status using a cross-sectional observational cohort.
