Metformin plus lifestyle interventions versus lifestyle interventions alone for the delay or prevention of type 2 diabetes in individuals with prediabetes: a meta-analysis of randomized controlled trials.

Objectives: We conducted this meta-analysis of randomized controlled trials (RCTs) to compare the efficacy of adding metformin to lifestyle interventions versus lifestyle interventions alone in individuals with prediabetes.

Materials And Methods: We searched four databases from inception until March 20, 2024. Our primary outcomes included the incidence of type 2 diabetes, hemoglobin A1c (HbA1c), and fasting plasma glucose (FPG).

Effectiveness of different appendiceal stump closure methods in laparoscopic appendectomy a network meta-analysis.

Purpose: Choosing the best stump closure method for laparoscopic appendectomy has been a debated issue, especially for patients with acute appendicitis. The lack of consensus in the literature and the diverse techniques available have prompted the need for a comprehensive evaluation to guide surgeons in selecting the most optimal appendiceal stump closure method.

Methods: A comprehensive search was conducted on multiple databases from inception until December 2023 to find relevant studies according to eligibility criteria.

AI chatbots show promise but limitations on UK medical exam questions: a comparative performance study.

Large language models (LLMs) like ChatGPT have potential applications in medical education such as helping students study for their licensing exams by discussing unclear questions with them. However, they require evaluation on these complex tasks. The purpose of this study was to evaluate how well publicly accessible LLMs performed on simulated UK medical board exam questions.

Rigid ring vs. flexible band for tricuspid valve repair in patients with tricuspid valve regurgitation: A systematic review and meta-analysis.

Background & Objectives: Rigid ring and Flexible band are techniques used to repair tricuspid valve regurgitation. The comparison between both techniques' effectiveness is controversial in the literature. We conducted this systematic review and meta-analysis to compare the safety and efficacy of rigid ring versus flexible band for tricuspid valve repair in patients with tricuspid valve regurgitation.

A comprehensive exploration of novel biomarkers for the early diagnosis of aortic dissection.

Aortic dissection (AD) is a catastrophic life-threatening cardiovascular emergency with a 1-2% per hour mortality rate post-diagnosis, characterized physiologically by the separation of aortic wall layers. AD initially presents as intense pain that can then radiate to the back, arms, neck, or jaw along with neurological deficits like difficulty in speaking, and unilateral weakness in some patients. This spectrum of clinical features associated with AD is often confused with acute myocardial infarction, hence leading to a delay in AD diagnosis.

Dynamics around small irregularly shaped objects modeled as a mass dipole.

In this work, we investigate the dynamics of a spacecraft near two primary bodies. The massive body is considered to have a spherical shape, while the less massive one is elongated and modeled as a dipole. The dipole consists of two connected masses, one is spherical and the other is an oblate spheroid.

Does fully closed-loop automated insulin delivery improve glycaemic control in patients with type 2 diabetes? A meta-analysis of randomized controlled trials.

Aims: This meta-analysis investigated the efficacy and safety of fully closed-loop automated insulin delivery (AID) in patients with type 2 diabetes.

Materials And Methods: We systemically searched PubMed, Scopus, Web of Science, and Cochrane Central from inception until April 26, 2023. We included randomized controlled trials (RCTs) comparing fully closed-loop AID versus conventional insulin therapy.
