Background And Objectives: Evidence syntheses systematically compile and analyze information from multiple sources to support health care decision making. As many different types of questions need to be answered in health care, different evidence synthesis types have emerged. In this article, we introduce the most common types of evidence synthesis.
Study Design And Setting: We discuss the aims, key methodological features and illustrative examples of different evidence synthesis types and modes, drawing on our work with the Evidence Synthesis Taxonomy Initiative.
Results: Evidence synthesis types include systematic reviews, overviews of reviews, qualitative evidence syntheses, mixed-methods reviews, and 'big picture reviews' (scoping reviews, mapping reviews, and evidence gap maps). Additionally, we focus on rapid and living reviews as modes and how they can be applied to different evidence synthesis types.
Conclusions: It is essential for clinicians and researchers to understand the main types of evidence synthesis to choose the most suitable method for addressing a specific health-related question.

Background: To review the biological functions of ergothioneine (ERGO), its correlation with plasma levels in cognitive frailty, and research progress in treating frailty and cognitive impairment, with the aim of providing a reference for ERGO application in cognitive frailty treatment.
Methods: A comprehensive review of existing literature on ERGO's chemical structure, sources, antioxidant and anti-inflammatory effects, and its role in cognitive frailty was conducted. Clinical trial data and metabolomic studies were also analyzed to understand ERGO's therapeutic potential.

Findable, Accessible, Interoperable, and Reusable (FAIR) data advances are becoming more common and more important across research fields given the large amount of research data in need of synthesis and application. Many novel methods improve the efficiency and accuracy of data reuse, combination, and synthesis, which is necessary given that there are over 500 published randomized controlled trials of posttraumatic stress disorder treatments in adults; however, these methods are still relatively new to the field of traumatic stress research. We provide a brief overview of relevant FAIR data efforts from other fields and within trauma health care and research; share examples of trauma-related FAIR data efforts to demonstrate recent advances and challenges; and suggest potential next steps to continue making trauma data more FAIR.

Alzheimer's disease (AD), a leading cause of dementia, represents a critical unmet global medical need. While the precise mechanisms underlying AD pathogenesis remain elusive, increasing evidence underscores the pivotal role of neuroinflammation in driving cognitive impairment. N6-methyladenosine (m6A), an epigenetic modification regulating RNA metabolism, has been found to be dysregulated in AD.

A major cause of cancer death, colorectal cancer is becoming more common in younger people. The comparative effectiveness of robotic versus laparoscopic total mesorectal excision (TME) as surgical interventions for mid-low rectal cancer following neoadjuvant chemoradiotherapy (nCRT) remains uncertain. To systematically evaluate oncological, perioperative, and survival outcomes of robotic versus laparoscopic surgery for mid-low rectal cancer following nCRT.

Cardiovascular-kidney-metabolic (CKM) syndrome is a term that is increasingly used to describe interconnected conditions that lead to poor health outcomes, including cardiovascular disease, chronic kidney disease, type 2 diabetes, and obesity. Historically, there have been very few targeted pharmacotherapies available that have changed cardiovascular outcomes for people with CKM syndromes; however, over the past decade, new pharmacologic options have rapidly expanded, with strong evidence for cardiovascular and kidney protective benefits in CKM conditions. Of note, sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists have emerged as key therapeutic options and are now widely guideline-endorsed.
