Background: Requiring authors to base their research on a systematic review of the existing literature prevents the generation of redundant scientific studies, thereby avoiding the deprivation of effective therapies for trial participants and the waste of research funds. Scientific medical journals could require this in their author guidelines. While this applies to all areas of research, it is also relevant to physiotherapy and rehabilitation research, which predominantly involve interventional trials in patients.
Objective: The aim of this study was to determine the extent to which the use of systematic reviews to justify a new trial is already being requested by physiotherapy-related scientific medical journals (PTJs). In addition, a comparison was made between PTJs and scientific medical journals with the highest impact factor in the Science Citation Index Extended (SCIE).
Methods: This meta-research study is based on a systematic examination of the author guidelines of 149 PTJs. The journals were identified and included based on the number of publications with physiotherapy as a keyword in the databases PEDro, and Medline (Pubmed). The included author guidelines were analysed for the extent to which they specified that a new trial should be justified by a systematic review of the literature. Additionally, they were compared with 14 scientific medical journals with the highest impact factor in the SCIE (LJs).
Results: In their author guidelines, none of the included PTJs required or recommended the use of a systematic review to justify a new trial. Among LJs, four journals (28.57%), all associated with the Lancet group, required the study justification through a systematic review of the literature.
Conclusion: Neither PTJs nor LJs require or recommend the use of a systematic review to justify a new trial in their author guidelines. This potentially leaves room for unethical scientific practices and should be critically considered in future research.

The issue of obesity continues to reach new levels globally, affecting individuals across the age continuum. Obesity in pregnancy is associated with myriad comorbidities which may negatively impact the fetus, particularly dysfunctional labor and failure to progress ending in unplanned cesarean delivery. Neuraxial anesthesia represents the gold standard for cesarean delivery anesthesia and is increasingly beneficial for obese patients due to the risk of difficult airway.

Study Question: How accurately can artificial intelligence (AI) models predict sperm retrieval in non-obstructive azoospermia (NOA) patients undergoing micro-testicular sperm extraction (m-TESE) surgery?
Summary Answer: AI predictive models hold significant promise in predicting successful sperm retrieval in NOA patients undergoing m-TESE, although limitations regarding variability of study designs, small sample sizes, and a lack of validation studies restrict the overall generalizability of studies in this area.
What Is Known Already: Previous studies have explored various predictors of successful sperm retrieval in m-TESE, including clinical and hormonal factors. However, no consistent predictive model has yet been established.

Background: Immune checkpoint inhibitors (ICIs) have been widely applicated for the treatment of patients with advanced esophageal cancer. Skin-related adverse reactions are frequent with ICIs, with toxic epidermal necrolysis (TEN) being a severe and potentially life-threatening cutaneous reaction.
Case Presentation: We present a case of a 70-year-old male with locally advanced esophageal cancer who developed severe toxic epidermal necrolysis (TEN) after 18 days of tislelizumab combined with chemotherapy.
Purpose: This study aimed to compare the return to sports, return to competition, Tegner score and anterior cruciate ligament-return to sports injury (ACL-RSI) scores between patients who underwent ACL reconstruction (ACLR) combined with anterolateral ligament reconstruction (ALLR) and those who underwent ACLR alone.
Methods: Two independent reviewers conducted a literature search in PubMed (MEDLINE), EMBASE, Google Scholar and the Cochrane Library in July 2024, followed by data extraction and quality assessment. This study followed the Preferred Reporting Items for Systematic Reviews and meta-analysis guidelines.
