Meta-analytic structural equation modeling (MASEM) combines the techniques of meta-analysis and structural equation modeling for the purpose of synthesizing correlation or covariance matrices and fitting structural equation models on the pooled correlation or covariance matrix. Both fixed-effects and random-effects models can be defined in MASEM. Random-effects models are well known in conventional meta-analysis but are less studied in MASEM. The primary objective of this paper was to address issues related to random-effects models in MASEM. Specifically, we compared two different random-effects models in MASEM-correlation-based MASEM and parameter-based MASEM-and explored their strengths and limitations. Two examples were used to illustrate the similarities and differences between these models. We offered some practical guidelines for choosing between these two models. Future directions for research on random-effects models in MASEM were also discussed. Copyright © 2016 John Wiley & Sons, Ltd.

Introduction: The Enhanced Recovery After Surgery (ERAS) protocol represents an advancement in perioperative care to reduce surgical stress and accelerate recovery. This meta-analysis evaluates the effectiveness of ERAS in pancreatic surgery.
Objective: To assess the impact of the ERAS protocol compared with conventional hospital care on postoperative outcomes, including length of hospital stay (LOS), hospital costs, readmission rates, and infection rates in patients undergoing pancreatic surgery.
Effectiveness of Virtual Reality for Pain Management in Musculoskeletal Disorders Across Anatomical Regions: A Systematic Review and Meta-Analysis.
Musculoskeletal Care

Laboratory of Healthcare Innovation Technologies, IRCCS San Camillo Hospital, Venice, Italy.
Introduction: The use of virtual reality (VR) in physiotherapy is expanding across various fields; however, while extensively researched in neurology, its application in musculoskeletal (MSK) disorders remains underexplored. This review aims to evaluate the effectiveness of VR in pain management across different anatomical regions.
Materials And Methods: The research was conducted using the MEDLINE (via PubMed), Cochrane Library, Scopus, Web of Science, and Embase databases, including randomized controlled trials that evaluated the effectiveness of VR interventions, encompassing immersive VR, specialised non-immersive VR, and gaming platforms.
Randomised controlled trials of dual antiplatelet therapy versus aspirin in patients with stroke or transient ischaemic attack: an updated meta-analysis.
Singapore Med J

Department of Radiology, Armed Forces Institute of Radiology, Pakistan.
Introduction: We explored the efficacy and safety of dual antiplatelet therapy (DAPT) for individuals diagnosed with stroke or transient ischaemic attack (TIA), incorporating the latest insights from randomised controlled trials (RCTs). The emerging evidence surrounding DAPT in stroke and TIA plays a pivotal role in guiding clinical decisions.
Methods: Our study included five RCTs (INSPIRES, THALES, POINT, CHANCE, FASTER) on DAPT (aspirin + P2Y12 inhibitor) initiated within 72 hours of acute stroke or TIA, which evaluated DAPT efficacy and safety over 21-90 days, focusing on new strokes and major bleeding.
Effects of pulmonary rehabilitation on respiratory function in mechanically ventilated patients: a systematic review and meta-analysis.

The First Affiliated Hospital of Sun Yat-Sen University, Guangdong, 510080, China.
Aim: The aim of this systematic review and meta-analysis was to explore the effects of different pulmonary rehabilitation on respiratory function in mechanically ventilated patients and to determine the optimal type of intervention.
Method: A comprehensive search was conducted using PubMed, Embase, Web of Science, Joanna Briggs Institute(JBI), and the Cochrane Library from their inception until September 16th, 2024. The search targeted randomized controlled trials (RCTs) comparing pulmonary rehabilitation or usual care, for improving respiratory function in mechanically ventilated patients.
