Clinical outcomes of transcatheter aortic valve replacement in patients with radiation-induced aortic stenosis: a systematic review and meta-analysis.

Background: Transcatheter aortic valve replacement (TAVR) is an effective treatment for severe aortic stenosis, particularly in high-risk patients unsuitable for surgical aortic valve replacement (SAVR). However, the efficacy of TAVR in patients with radiation-induced aortic stenosis remains uncertain and controversial. This meta-analysis evaluates clinical outcomes of TAVR in patients with prior chest radiation (C-XRT).

The impact of weight loss interventions on thyroid function: a systematic review and meta-analysis.

Background: This study explores how weight loss impacts thyroid hormone levels, particularly free T3 (FT3) and FT4, in obese individuals, given the key role these hormones play in regulating metabolism and gene expression.

Methods: A comprehensive literature search in PubMed, ISI/Web of Science, and Scopus databases identified studies examining the correlation between weight, body mass index (BMI), and thyroid hormone levels.

Results: The analysis revealed that BMI reduction significantly decreases FT3 levels [odds ratio (OR) = 2.

Preoperative risk factors for laparoscopic to open appendectomy conversion: a systematic review and meta-analysis.

Background: Laparoscopic appendectomy (LA) is a standard treatment for acute appendicitis (AA), offering reduced complications and improved patient outcomes. However, in certain cases, the need for conversion to open appendectomy (OA) may arise. The present systematic review and meta-analysis aimed to identify preoperative risk factors associated with conversion from LA to OA.

Clinical outcomes of transcatheter edge-to-edge repair in patients with acute mitral regurgitation complicated by cardiogenic shock: a systematic review and meta-analysis.

Background: Acute mitral regurgitation (AMR) complicated by cardiogenic shock (CS) is a critical cardiovascular emergency associated with high morbidity and mortality. Surgical intervention is often not feasible due to the unstable clinical status of these patients. Transcatheter edge-to-edge repair (TEER) has emerged as a minimally invasive alternative, yet its safety and efficacy in this specific population remain uncertain.

Research trends in CAR-T cell therapy: A comprehensive bibliometric analysis highlighting cardiovascular toxicity and clinical implications.

Background: Chimeric antigen receptor T cell (CAR-T) therapy is an innovation in oncology, which provides targeted treatment alternatives for certain tumors. CAR-T therapy has been associated to adverse cardiovascular consequences despite its potential for therapeutic benefit. As research in this field expands rapidly, a bibliometric study is needed to map the current state of knowledge and highlight emerging areas of interest to guide future studies and optimize patient outcomes.

Prevalence of metabolic syndrome in ankylosing spondylitis: a multi national meta-analysis study.

Background: Ankylosing spondylitis (AS) is a chronic inflammatory disease associated with an increased risk of metabolic syndrome (MetS), a cluster of cardiometabolic risk factors. However, the prevalence of MetS in AS remains uncertain. This meta-analysis estimates the global prevalence of MetS in AS patients and identifies factors contributing to its variability.

The predictive value of endocan as a novel biomarker: an umbrella study on meta-analyses.

Background And Aim: In recent years, endocan has emerged as a potential biomarker in various medical conditions. This multifaceted molecule, involved in key processes such as inflammation and endothelial dysfunction, has shown promise in predicting disease progression and therapeutic response across a spectrum of pathologies. However, the heterogeneity of studies and the complexity of endocan's role in different diseases necessitate a comprehensive review.

Artificial intelligence in cardiovascular procedures: a bibliometric and visual analysis study.

Background: The integration of artificial intelligence (AI) into cardiovascular procedures has significantly advanced diagnostic accuracy, outcome prediction, and robotic-assisted surgeries. However, a comprehensive bibliometric analysis of AI's impact in this field is lacking. This study examines research trends, key contributors, and emerging themes in AI-driven cardiovascular interventions.

Exploring the evolution of evidence synthesis: a bibliometric analysis of umbrella reviews in medicine.

Background: Umbrella review studies have become increasingly vital in evidence synthesis, offering a comprehensive overview by analyzing multiple systematic reviews and meta-analyses. This bibliometric study aimed to delineate the growth and thematic evolution of umbrella reviews within evidence-based medicine, illuminating their integral role in synthesizing high-level evidence.

Methods: Utilizing the Web of Science Core Collection, we performed a search for publications on umbrella reviews, identifying relevant articles through a refined strategy.

Clinical Outcomes and Prognostic Implications of TAVR in Patients With Active Cancer: A Meta-Analysis.

Background: Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) for high-risk patients with severe aortic stenosis (AS). However, the clinical outcomes and prognostic implications of TAVR in patients with active cancer remain uncertain. This meta-analysis evaluates procedural success, complications, and survival outcomes of TAVR in patients with and without active cancer.

Gut microbiota interventions in type 2 diabetes mellitus: An umbrella review of glycemic indices.

Background: We aimed to explore how probiotics, prebiotics, or synbiotics impact glycemic indices in patients with diabetes mellitus.

Method: A comprehensive search was conducted on PubMed, Scopus, and Web of Science from inception up to April 2023. The random-effects model was employed for the study analysis.

Global Prevalence of Nonalcoholic Fatty Liver Disease: An Updated Review Meta-Analysis comprising a Population of 78 million from 38 Countries.

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.

Efficacy of Radiofrequency Ablation in Autonomous Functioning Thyroid Nodules: A Comprehensive Systematic Review and Meta-analysis.

Background: Radiofrequency ablation (RFA) is a minimally invasive outpatient procedure that has recently emerged as a treatment option for autonomous functioning thyroid nodules (AFTNs), offering a less invasive alternative to surgery. The objective of this systematic review and meta-analysis is to evaluate the efficacy of RFA for AFTNs.

Method: Global databases of PubMed, Scopus, Embase, Web of Science, and Cochrane Library were systematically searched from 1990 until January 5, 2024, for studies on AFTNs undergoing RFA that presented volume reduction ratio (VRR) for at least one of 1, 3, 6 or 12 months post-operative follow-up with the results presented as means.

Can modulation of gut microbiota affect anthropometric indices in patients with non-alcoholic fatty liver disease? An umbrella meta-analysis of randomized controlled trials.

Background And Aim: Modulating the gut microbiota population by administration of probiotics, prebiotics, and synbiotics has shown to have a variety of health benefits in different populations, particularly those with metabolic disorders. Although the promising effects of these compounds have been observed in the management of patients with non-alcoholic fatty liver disease (NAFLD), the exact effects and the mechanisms of action are yet to be understood. In the present study, we aimed to evaluate how gut microbiota modulation affects anthropometric indices of NAFLD patients to achieve a comprehensive summary of current evidence-based knowledge.

The impact of pre-stroke metformin use on clinical outcomes after acute ischemic stroke: A systematic review and meta-analysis.

Objectives: Stroke is a leading cause of mortality and disability globally, with limited treatment options available for acute ischemic stroke (AIS) patients.
