Introduction: Sex-related differences in the epidemiology of malignant gliomas are acknowledged; however, information regarding their clinical characteristics and outcomes after surgery is limited.
Research Question: To identify sex-specific differences of all patients with high-grade glioma at our institution and assessed clinical outcomes and prognostic factors.
Material And Methods: This single-center study included those who underwent surgery for malignant gliomas between 2010 and 2020. Categorical, normally distributed, and skewed continuous variables were compared between men and women using the chi-square test, independent samples -test, and Mann-Whitney test, respectively. Survival was calculated using the log-rank and Kaplan-Meier methods.
Results: In total, 621 patients with WHO grade IV gliomas were identified (370 (59.58%) male). Men were significantly younger, underwent surgery faster after imaging diagnosis, and had a slightly higher surgical complications incidence than women. Women reported a worse preoperative performance status. Multivariate analysis showed that sex did not affect survival, surgical complications, nicotine or alcohol abuse, or preoperative tumor volume. Age, Karnofsky performance status, neurosurgical resection, and adjuvant radiotherapy with temozolomide showed a survival advantage.
Discussion And Conclusions: Men are diagnosed with malignant glioma at a younger age than women; however, no advantage in clinical outcomes was observed. No sex-related differences were observed.

Importance: Rotator cuff tendinopathy represents the most prevalent cause of shoulder pain, the third most common musculoskeletal disorder after low back pain and knee pain.
Objective: The objective of this study was to determine the effectiveness of corticosteroid injection(s), alone or in combination with anesthetic injection or any other physical therapist interventions, compared to physical therapist interventions alone in adults with rotator cuff tendinopathy.
Design: This study was a systematic review and meta-analysis of randomized controlled trials.
Mindfulness Training vs Recovery Support for Opioid Use, Craving, and Anxiety During Buprenorphine Treatment: A Randomized Clinical Trial.
JAMA Netw Open
January 2025
Department of Psychiatry, Harvard Medical School, Boston, Massachusetts.
Importance: During buprenorphine treatment for opioid use disorder (OUD), risk factors for opioid relapse or treatment dropout include comorbid substance use disorder, anxiety, or residual opioid craving. There is a need for a well-powered trial to evaluate virtually delivered groups, including both mindfulness and evidence-based approaches, to address these comorbidities during buprenorphine treatment.
Objective: To compare the effects of the Mindful Recovery Opioid Use Disorder Care Continuum (M-ROCC) vs active control among adults receiving buprenorphine for OUD.
Factors Associated With Semaglutide Initiation Among Adults With Obesity.
JAMA Netw Open
January 2025
Department of Global Health, School of Public Health, Boston University, Boston, Massachusetts.
Importance: Semaglutide, a novel glucagon-like peptide-1 (GLP-1) receptor agonist medication, was approved for weight management in individuals with obesity in June 2021. There is limited evidence on factors associated with uptake among individuals in this subgroup without diabetes.
Objective: To explore factors associated with semaglutide initiation among a population of commercially insured individuals with obesity but no diagnosed diabetes.
Use of Albumin-Adjusted Calcium Measurements in Clinical Practice.
JAMA Netw Open
January 2025
Division of Endocrinology and Metabolism, Department of Medicine, University of Calgary, Calgary, Alberta, Canada.
Importance: Using albumin-adjusted calcium is commonly recommended for for measuring calcium, but with little empirical evidence to support the practice.
Objective: To assess the correlation between total calcium measurements (with or without adjustment) vs the ionized calcium level as a reference standard.
Design, Setting, And Participants: This was a population-based cross-sectional study in the province of Alberta, Canada, including adults tested for serum total calcium and ionized calcium simultaneously between January 1, 2013, and October 31, 2019.
Travel Time as an Indicator of Poor Access to Care in Surgical Emergencies.
JAMA Netw Open
January 2025
Department of Surgery, University of Washington, Seattle.
Importance: Timely access to care is a key metric for health care systems and is particularly important in conditions that acutely worsen with delays in care, including surgical emergencies. However, the association between travel time to emergency care and risk for complex presentation is poorly understood.
Objective: To evaluate the impact of travel time on disease complexity at presentation among people with emergency general surgery conditions and to evaluate whether travel time was associated with clinical outcomes and measures of increased health resource utilization.
