Assessment of Helicobacter pylori infection in Lebanon: Endoscopic and histopathological findings.
J Infect Public Health
January 2025
Department of Medical Laboratory Sciences, Faculty of Health Sciences, Beirut Arab University, Beirut 11-5020, Lebanon. Electronic address:
Helicobacter pylori (H. pylori), a pervasive pathobiont, colonizes the gastric mucosa and plays a crucial role in the pathogenesis of several gastroduodenal pathologies ranging from chronic gastritis to more severe disorders including peptic ulcer disease, gastric mucosa-associated lymphoid tissue lymphoma, and gastric adenocarcinoma. In symptomatic patients, endoscopy and histological examination of the gastric mucosa are the preferred tests for diagnosing H.

Initial evaluations, including laboratory tests and imaging, were unremarkable, prompting a series of diagnostic and therapeutic interventions. A multidisciplinary approach, including empiric gastroesophageal reflux disease (GERD) therapy, was started.

Background: Diagnosis of sarcoidosis often involves endobronchial biopsy (EBB), but studies have shown varying yields for EBB in suspected sarcoidosis, partly due to differences in identifying abnormal mucosa under white light (WL). Narrow band imaging (NBI) may assist in the visualization of abnormal mucosa, but its role in sarcoidosis remains to be characterized.
Methods: Individuals referred for suspected sarcoidosis were considered for enrollment.
Ag85B-Induced M1 Macrophage Polarization via the TLR4/TRAF6/NF-κB Axis Leading to Bronchial Epithelial Cell Damage and TH17/Treg Imbalance.

January 2025
Endoscopy Center, Hunan Chest Hospital, Changsha, 410016, China.
Background: Antigen 85B (Ag85B) is a signature antigen of Mycobacterium tuberculosis (MTB). In this study, we aimed to investigate the impact of macrophages stimulated with Ag85B on bronchial epithelial cells and T cells, as well as the underlying mechanisms involved.
Methods: We used Ag85B to stimulate macrophage and investigated the impact of Ag85B on macrophage polarization.
Background: Predicting successful outcomes of gastric peroral endoscopic myotomy (G-POEM) is essential for identifying patients who are most likely to benefit from the procedure. This study aimed to evaluate the utility of the balloon dilation test (BDT) in optimizing patient selection for G-POEM.
Methods: A retrospective study was conducted from February 2021 to December 2023, including patients with refractory gastroparesis unresponsive to conventional medical treatments.
