Article Abstract
Background: Tranexamic acid (TXA) is widely used to reduce blood loss in spine surgery. Different administration routes, including intravenous (IV), topical, and oral, have been studied, but a comprehensive comparison of their efficacy and safety remains lacking. This network meta-analysis aims to compare the effectiveness and safety of various TXA administration methods in spine surgery, focusing on blood loss, transfusion rates and other perioperative parameters.
Methods: We systematically reviewed randomized controlled trials (RCTs) published until January 2025, comparing different TXA regimens in spine surgery. Data on blood loss, transfusion rates, postoperative complications, post-drainage, length of hospital stay and operative time are extracted. A network meta-analysis is conducted using a Bayesian random effects model to rank the efficacy and safety of TXA routes.
Results: A total of 12 RCTs involving 1980 patients are included. Topical TXA + IV TXA demonstrated the highest efficacy in reducing intraoperative blood loss, post-operative blood loss, overall blood loss, Hct, Hgb, transfusion rates, post-drainage, operative time and hospital stay, with the highest probability of being the best treatment. Oral TXA showed fewer complications, making it a safer option for low-risk patients. Subgroup analysis confirmed the superiority of topical TXA + IV TXA in spine fusion surgeries, particularly for overall blood loss control and reducing transfusion requirements.
Conclusion: For open thoracolumbar fusion surgery, Topical TXA + IV TXA is the most effective regimen for reducing blood loss and enhancing recovery in high-risk surgeries. Oral TXA offers a safer alternative for low-risk patients. Extrapolating these findings to other spine procedures still requires further randomized controlled trials. Tailoring TXA administration to individual patient needs optimizes outcomes and reduces complications.

J Craniofac Surg
September 2025
Division of Plastic Surgery, Stanford University School of Medicine, Stanford.
Background: Spring-mediated cranioplasty (SMC) is a safe and effective treatment for craniosynostosis. The authors describe the largest cohort of endoscopic SMC for coronal craniosynostosis to date, highlighting the evolution of their technique.
Methods: The authors retrospectively reviewed patients who underwent endoscopic coronal suturectomy and SMC between 2017 and 2023.
A Retrospective Review of Craniosynostosis Reconstruction at a Community Children's Hospital Compared With Academic Centers.
J Craniofac Surg
September 2025
Department of Pediatric Plastic and Reconstructive Surgery, Children's Hospital Colorado.
Background: Craniosynostosis repair is traditionally performed at high-volume academic centers with multidisciplinary teams. Access barriers in rural or suburban regions raise the question of whether comparable outcomes can be achieved and if this surgery can be performed safely in community settings.
Objective: To evaluate the safety and perioperative outcomes of cranial vault reconstruction for craniosynostosis performed at a community-based children's hospital and compare these outcomes to those reported at academic institutions.
Changes in antral follicle dynamics following weight loss in women with polycystic ovary syndrome.
Hum Reprod
September 2025
Division of Nutritional Sciences, Cornell University, Ithaca, NY, USA.
Study Question: Does weight loss from a hypocaloric dietary intervention improve antral follicle dynamics in women with PCOS?
Summary Answer: During a 3-month hypocaloric dietary intervention, women with PCOS who experienced clinically meaningful weight loss showed more organized antral follicle development including fewer recruitment events, but no change in the overall frequency of selection, dominance, or ovulation.
What Is Known Already: There is a spectrum of disordered antral follicle development in women with PCOS including excessive follicle recruitment and turnover, decreased frequency of selection and dominance, and failure of ovulation. Lifestyle intervention aimed at weight loss is recommended to improve metabolic health in women with PCOS yet benefits on ovarian follicle development and ovulation are unclear.
COMPARING THE PREDICTIVE EFFICACY OF MELD AND ALBI SCORES IN LIVER CIRRHOSIS PATIENTS WITH ACUTE UPPER GASTROINTESTINAL BLEEDING.
Arq Gastroenterol

Alimentary Tract Research Center, Clinical Sciences Research Institute, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.
Background: Acute upper gastrointestinal bleeding (AUGIB) is a critical medical emergency and is a common cause of illness and death in individuals with liver cirrhosis.
Objective: The point of this study was to check how well the albumin-to-bilirubin ratio (ALBI) and model for end-stage liver disease (MELD) scores could predict how these patients would do in the future.
Methods: The Imam Khomeini Hospital gastroenterology department conducted a retrospective examination.
