Introduction: Endoscopic submucosal dissection (ESD) allows for curative en-bloc resection of dysplastic gastrointestinal (GI) tract lesions. However, it is associated with postoperative adverse events (AEs) such as pain, bleeding, and perforation. Dexmedetomidine, an α2-receptor agonist, has emerged as a promising adjunct sedative for ESD under moderate sedation, offering anxiolysis and analgesia.

Article Synopsis
  • Acute pancreatitis (AP) is a serious health issue that can recur, especially among individuals with type 2 diabetes (T2D) or obesity; this study examines how GLP-1 receptor agonists (GLP-1RAs) impact the recurrence risk of AP.
  • Researchers analyzed data from over 258,000 patients with T2D or obesity and a history of AP, finding that those who used GLP-1RAs had significantly lower recurrence rates compared to non-users.
  • Specifically, Semaglutide and Tirzepatide users showed the best outcomes, with Tirzepatide presenting the lowest recurrence risk at 6.2%, suggesting the need for

Background: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are increasingly used to manage type 2 diabetes (T2D) and obesity. Despite their recognized benefits in glycemic control and weight management, their impact on broader systemic has been less explored.

Objective: This study aimed to evaluate the impact of GLP-1RAs on a variety of systemic diseases in people with T2D or obesity.

Type 1 diabetes (T1D) is a chronic autoimmune condition that destroys insulin-producing beta cells in the pancreas, leading to insulin deficiency and hyper-glycemia. The management of T1D primarily focuses on exogenous insulin replacement to control blood glucose levels. However, this approach does not address the underlying autoimmune process or prevent the progressive loss of beta cells.

Article Synopsis
  • The study aimed to evaluate the link between non-alcoholic fatty liver disease (NAFLD) and various cardiovascular issues, including angina and heart attacks.
  • A thorough review of existing research included 32 studies with over 5.6 million participants, finding that NAFLD significantly increases the risk of several cardiovascular problems.
  • The results highlight the need for better prevention and management strategies for NAFLD, even after considering traditional risk factors for heart disease.

Background: Non-alcoholic fatty liver disease (NAFLD) has become a prevalent cause of chronic liver disease and ranks third among the causes of transplantation. In the United States alone, annual medical costs are approximately 100 billion dollars. Unfortunately, there is no Federal Drug Administration (FDA)-approved medication for its treatment.

Background: Heart and kidney dysfunction frequently coexist in patients with acute heart failure due to the overlap between these two organ systems. Cardiorenal syndrome (CRS) results from pathology occurring in the heart and kidneys along with the consequences of dysfunction in one organ contributing to dysfunction in the other and vice versa.

Aim: To evaluate the use of erythropoietin (EPO) in patients with CRS and its effects on hemoglobin (Hb), major cardiovascular (CV) events, and hospitalization rates.

Background And Aims: Diabetic retinopathy (DR) is one of the most common microvascular diabetic complications. Sarcolemmal membrane-associated protein (SLMAP) has been implicated in playing a role in microvascular endothelial dysfunction. This study aimed to assess the significance of SLMAP rs17058639C > T gene polymorphism among patients with type 2 diabetes mellitus (T2DM) and its relevance to microvascular endothelial diabetic retinopathy.

Background And Aims: This study aimed to review the available data on the role of coronary artery calcium (CAC) scoring as the preferred adjunct modality to improve risk prediction and reduce the incidence of major adverse cardiac events and mortality in T2DM patients.

Methods: We reviewed the findings of 21 studies.

Results: This study revealed that the CAC scoring system could enhance cardiovascular disease (CVD) risk stratification and positively affect the medical management of patients with T2DM.
