Volume 18, Issue 6 (11-2024)
Abstract
Background: Upper gastrointestinal (GI) lesions are significant contributors to morbidity, with endoscopy serving as a crucial minimally invasive tool for their visualization and biopsy. This study explores the demographic patterns of upper GI lesions by age, sex, and biopsy site, comparing the prevalence of neoplastic and non-neoplastic lesions across the esophagus, stomach, and duodenum, while underscoring the importance of early detection and management.
Methods: This cross-sectional retrospective study was conducted at a tertiary care center in Gujarat, India, from July 2019 to October 2021. A total of 104 upper GIT biopsies were included and categorized based on age, sex, site, endoscopic findings, and histomorphology. Histopathological analysis involved routine processing, staining, and microscopic examination by a histopathologist.
Results: Out of the 104 endoscopic biopsies, the majority were from the 46-55 age group, followed by the 66-75 age group, with a male-to-female ratio of 1.7:1. Esophageal biopsies were the most common (48%). Non-neoplastic lesions (52.8%) were predominant, with duodenitis (48%) and celiac disease (33.3%) being the most frequent. Neoplastic lesions (47.1%) were prevalent in the esophagus (36.5%), primarily squamous cell carcinoma. Gastric biopsies showed more benign lesions, such as gastritis, than malignant ones, with adenocarcinoma being the most common. Endoscopic findings included thickening, scalloping, nodularity, polyps, and fragile growths, emphasizing the diversity of upper GIT lesions and the need for early detection and treatment.
Conclusion: The study emphasizes the crucial role of biopsies in promptly diagnosing esophageal malignancies and identifying premalignant conditions like Barrett's esophagus for timely intervention. It reaffirms the pivotal role of endoscopic biopsy in clinical management, stressing the necessity of a multidisciplinary approach.
 

Investigation of simultaneous effect of resistance training and atorvastatin in improving nonalcoholic fatty liver disease in Rats fed high fat/fructose diet

Volume 19, Issue 2 (3-2025)
Abstract
Background and objectives: Non-alcoholic fatty liver disease (NAFLD), a highly prevalent and chronic liver disease, is characterized by a diverse range of conditions that span across a broad spectrum. Engaging in consistent physical activity has proven to be a successful method in effectively managing NAFLD, as it has demonstrated the ability to enhance crucial elements implicated in the development of the condition
Methods: Twenty-one male Wistar rats were divided into three groups: 1) NAFLD, 2) NAFLD + resistance training (RT), 3) NAFLD + RT + atorvastatin (ATO). The groups received high fat/fructose diet (HFFD) to induce NAFLD and it was confirmed through evaluation of histopathological analysis (H&E staining) and measurement of aminotransferase enzymes. ATO was administrated at the dose of 2 mg/kg/day. The interventions were done for eight weeks.
Results: Triglyceride (TG), Alanine transaminase (ALT), and aspartate transaminase (AST) were significantly reduced in the NAFLD + RT + ATO. Also, low-density lipoprotein (LDL) had lower level in NAFLD + RT in compared to NAFLD + RT + ATO. Alkaline phosphatase (ALP) was reduced in both NAFLD + RT and NAFLD + RT + ATO groups compared to NAFLD. There was no significant difference in weight between the groups except first, second, and forth week.
Conclusion: RT in combination with the administration of ATO can be deemed as an efficacious and supplementary strategy for the purpose of effectively controlling and addressing NAFLD.

Volume 19, Issue 2 (3-2025)
Abstract
Background: Gastric cancer (GC) is one of the widespread gastrointestinal tumors in the worldwide, with mortality rates among the highest. In the world, we face more than one million newly diagnosed stomach cancer patients every year. Various factors closely associated with formation of GC. One of these factors is the change in the level of components of the extracellular matrix in the microenvironment of the stomach tumor. Fibulins are one of the secreted glycoproteins of extracellular matrix, which are known as matrix organizers. The purpose of this study is to investigate the changes in fibulins in gastric tumor tissue compared to control samples.
Methods: Scopus, PubMed, and Web of Science databases were searched for articles that examined FBLN gene family and protein expression in patients with gastric cancer and gastric cancer cell lines.
Results: A total of 853 gastric cancer tumor samples, ranging from 8 to 197 per study, were analyzed across eight studies published between 2008 and 2023, all conducted in China. Several gastric cancer cell lines were also included, such as AGS, Kato III, MKN28, MKN45, SNU1, SNU16, NCI-N87, MGC-803, BGC-823, SGC-7901, and HGC27. Tumor size was reported in 4 studies, while histopathological grade and lymph node metastasis were each evaluated in 4 studies.
Conclusion: The downregulation of Fibulin-1 and Fibulin-2 supports their potential tumor-suppressive roles in gastric cancer, while the upregulation of Fibulin-5 is associated to tumor progression and worse prognosis, making it a candidate biomarker for aggressive disease.
