Background: Artificial intelligence (AI) has revolutionized the field of gastroenterology, particularly in endoscopic and colonoscopic procedures. These AI technologies aim to enhance diagnostic accuracy by facilitating the detection of gastrointestinal lesions, such as polyps and neoplasms. However, the rapid expansion of research in this area necessitates a comprehensive analysis to assess global trends and contributions.

Background: Dipeptidyl peptidase-4 (DPP-4) inhibitors are oral antihyperglycemic agents commonly prescribed for type 2 diabetes (T2DM). Due to the intricate relationship between glucose regulation and cardiovascular diseases (CVDs), DPP-4 inhibitors have attracted attention for their cardiovascular safety and efficacy. This bibliometric analysis aims to provide insights into the global research landscape on DPP-4 inhibitors and cardiovascular outcomes (CVOs).

Background & Aims: Type 2 diabetes mellitus (T2DM) poses a significant global health challenge due to various lifestyle factors contributing to its prevalence and associated complications. Chronic low-grade inflammation, characterized by elevated levels of inflammatory markers such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), plays a pivotal role in the pathogenesis of T2DM. Modulation of the gut microbiota through microbiome-targeted therapy (MTT), including probiotics, prebiotics, and synbiotics, has emerged as a potential strategy to mitigate inflammation and improve metabolic outcomes in T2DM.

Background: Primary aldosteronism (PA) is now recognized as the most prevalent form of secondary hypertension globally, contributing significantly to cardiovascular morbidity and mortality. This umbrella review aims to systematically compare cardiovascular outcomes and all-cause mortality in PA patients undergoing adrenalectomy versus mineralocorticoid receptor antagonist (MRA) treatment, aiming to inform optimal management strategies.

Method: Following PRISMA guidelines (Supplemental Digital Content 1, http://links.

Article Synopsis
  • This umbrella review synthesizes findings from previous meta-analyses about the Triglyceride and Glucose (TyG) Index to inform clinicians and policymakers about its clinical relevance and potential health outcomes.
  • The review included a total of 32 studies and used comprehensive methods to analyze how the TyG index correlates with various health issues, like increased risks of kidney diseases, type 2 diabetes, and specific metabolic conditions.
  • Notably, a high TyG index is linked to serious health risks, including chronic kidney disease, diabetes, cognitive impairments, and cardiovascular problems, highlighting its significance as a biomarker in clinical settings.

Background: Nonalcoholic fatty liver disease (NAFLD) is a global health challenge, with a rising rate in line with other metabolic diseases. We aimed to assess the global prevalence of NAFLD in adult and pediatric populations.

Methods: PubMed, Scopus and Web of Science databases were systematically searched up to May 2023.

Glutamatergic imbalance, particularly downregulation of -amino-3-hydroxy-5-methyl-4- isoxazole propionic acid receptor (AMPARs) endocytosis, has been addressed as a possible reason for cognitive dysfunctions in Alzheimer's disease (AD). We hypothesized that inhibition of AMPAR endocytosis may ameliorate memory impairment in AD model of rats. To approach this, twenty-four adults male Wistar rats were divided into three groups: saline + saline (control group), A + saline, and A + Tat-GluR23Y (AMPA endocytosis inhibitor).

Article Synopsis
  • Type 2 diabetes is a key factor contributing to non-alcoholic fatty liver disease (NAFLD), leading to increased fasting blood sugar, insulin levels, and insulin resistance in affected patients.
  • This meta-umbrella study analyzed existing research on how gut microbial treatments (probiotics, prebiotics, and synbiotics) influence glycemic indices in NAFLD patients.
  • Results indicated that these treatments significantly lowered insulin resistance and fasting insulin levels, but had no notable impact on fasting blood sugar levels.

Article Synopsis
  • - The meta-analysis examined the impact of a positive family history of cancer on colorectal cancer (CRC) risk in EMRO countries, analyzing 27 relevant articles from databases like PubMed and Scopus.
  • - The research utilized the Newcastle-Ottawa checklist to ensure article quality and calculated odds ratios (OR) to compare cases with controls, revealing a significant association between family history and CRC risk (OR 2.21; P < 0.001).
  • - The findings emphasize the need for timely screening and early detection for at-risk individuals, suggesting that improved coordination in healthcare facilities and increased screening could lower CRC mortality rates and financial costs for the public.

Background: Smoking poses a significant risk for colorectal cancer (CRC), considered the third leading reason for cancer-related deaths worldwide. However, there has been limited research on the relationship between smoking and CRC in the Eastern Mediterranean Regional Office (EMRO). Therefore, a meta-analysis was conducted to combine available data and gain a comprehensive understanding of the relationship between smoking and CRC in EMRO.

Objective: Burn trauma is a life-threatening incident that may be accompanied by several risk factors that increase morbidity and mortality. Drug abuse is one of the lifestyle dangers on the rise globally and can have an impact on the outcomes of burn injuries. This study aimed to evaluate the effect of drug abuse on the clinical outcomes of adult burn patients who were admitted to a burn center in the North of Iran.
