Background: Lumbar disk herniation (LDH) is one of the main causes of discogenic low back pain. However, the evidence comparing different approaches for discectomy has lacked definitive conclusions, with conflicting results regarding the benefit of minimally invasive versus open techniques for LDH. We are now conducting a randomized controlled trial to figure out whether or not microendoscopic discectomy yields better clinical outcomes and causes less surgical trauma than open surgery.
Methods: This prospective, randomized, single-blind, controlled, superiority clinical trial was approved by the institutional review board in the People's Hospital of Jianyang City. The conduct of this study followed the Declaration of Helsinki principles and the reporting of this study adhered to the Consolidated Standards of Reporting Trials guidelines for randomized controlled trials. Subjects were randomized into 2 groups as follows: open surgery and microendoscopic group. The outcomes included pain score, functional outcome, satisfaction rate, radiological outcomes, and complications. The statistical analyses in this study were performed using the Statistical Package for the Social Sciences 20.0 software. P < .05 was accepted as statistically significant.
Results: The hypothesis was that the open technique would achieve similar clinical outcomes as compared to the microendoscopic technique in LDH.
Trial Registration: This study protocol was registered in Research Registry (researchregistry5708).

A Descriptive Analysis of the Seasonal Patterns of Bone Stress Injury Incidence in Division I Collegiate Distance Runners.
Am J Sports Med
January 2025
Department of Orthopaedic Surgery, Division of Physical Medicine and Rehabilitation, Stanford University, Stanford, California, USA.
Background: A bone stress injury (BSI) is a common overuse injury in collegiate athletes, particularly cross-country and track and field runners. Limited work describes the seasonality of BSIs or the differences in rates and anatomic locations of BSIs in collegiate runners.
Purpose: To describe seasonally related trends in anatomic locations of BSIs in National Collegiate Athletic Association (NCAA) Division I male and female middle- and long-distance runners.
MAPK pathway activating alteration and immunotherapy efficacy in squamous cell lung carcinoma: results from the randomized, prospective SQUINT trial.
Clin Cancer Res
January 2025
Istituti Fisioterapici Ospitalieri, Italy.
Background: The role of activating alterations in the MAPK pathway in predicting immunotherapy efficacy in lung squamous cell carcinoma (LSCC) patients is largely unknown. The aims of the randomized, phase II SQUINT trial were to assess the efficacy of nivolumab plus ipilimumab (NI) versus platinum-based chemotherapy plus nivolumab (N-CT) and to identify clinically available biomarkers of response to immunotherapy in patients with advanced or metastatic LSCC.
Methods: SQUINT was an open-label, randomized, parallel, non-comparative, phase II trial of NI versus N-CT in chemo-naïve, metastatic or recurrent LSCC adult patients.
Return to Sport and Graft Failure Rates After Primary Anterior Cruciate Ligament Reconstruction With a Bone-Patellar Tendon-Bone Versus Hamstring Tendon Autograft: A Systematic Review and Meta-analysis.
Am J Sports Med
January 2025
Department of Orthopedic Surgery, Boston Medical Center, Boston, Massachusetts, USA.
Background: Anterior cruciate ligament (ACL) tears are frequent injuries in athletes that often require surgical reconstruction so that patients may return to their previous levels of performance. While existing data on patient-reported outcomes are similar between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) autografts, the literature regarding return to sport (RTS), return to previous levels of sport activity, and graft failure rate remains limited.
Purpose: To compare rates of RTS, return to previous activity levels, and graft retears among athletes undergoing primary ACL reconstruction using a BTB versus HT autograft.
Efficacy and safety of laser interstitial thermal therapy versus radiofrequency ablation and stereotactic radiosurgery in the treatment of intractable mesial temporal lobe epilepsy: a systematic review and meta-analysis.
Neurosurg Rev

Department of neurosurgery, Faculty of Medicine, Mansoura University, Mansoura, Egypt.
Epilepsy is a common neurological disease that is treated with medications; however, patients with drug-resistant epilepsy, commonly intractable temporal lobe epilepsy, tend to have better control with surgical treatment. While the mainstay of surgical treatment is anterior temporal lobectomy, it carries risk of potential adverse effects hence minimally invasive techniques are now being used as an alternative to open surgery. This systematic review and meta-analysis compare the efficacy and safety of three of the most used techniques: laser interstitial thermal therapy (LITT), radiofrequency ablation (RFA) and stereotactic radiosurgery (SRS).

Department of Gastroenterology, Hospital das Clinicas HCFMUSP, Faculdade de Medicina, Universidade de Sao Paulo, São Paulo, Brazil.
Background: Gastric outlet obstruction due to unresectable tumours is usually managed with a gastrojejunostomy. Unfortunately, the unsatisfactory outcomes of this procedure have led to the search for alternatives, including gastric partitioning.
Methods: Monocentric, randomized, parallel, open-label trial that included patients with obstructive, unresectable distal gastric tumours.
