Article Abstract
Background: The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years.
Methods: Analysis of primary and secondary endpoints at two years of follow-up was prespecified in the study protocol. We report the study results for the extended follow-up time here.
Results: In total, 6006 patients were enrolled, 3005 with ST-segment elevation MI (STEMI) and 3001 with Non-STEMI (NSTEMI), representing 70 % of all eligible patients with these diagnoses during the study. The primary endpoint occurred in 14.0 % (421 of 3004) in the bivalirudin group compared with 14.3 % (429 of 3002) in the heparin group (hazard ratio [HR] 0.97; 95 % confidence interval [CI], 0.85-1.11; P = 0.70) at one year and in 16.7 % (503 of 3004) compared with 17.1 % (514 of 3002), (HR 0.97; 95 % CI, 0.96-1.10; P = 0.66) at two years. The results were consistent in patients with STEMI and NSTEMI and across major subgroups.
Conclusions: Until the two-year follow-up, there were no differences in endpoints between patients with MI undergoing PCI and allocated to bivalirudin compared with those allocated to heparin.

Effect of virtual reality on perioperative anxiety, stress and pain in total hip arthroplasty: a randomized controlled trial.
BMC Anesthesiol
September 2025
Faculty of Medicine, Anesthesiology, Surgical Intensive Care and Pain Medicine Department, Tanta University, Tanta, El Gharbia, 31511, Egypt.
Background: Virtual reality (VR) has shown promise as a nonpharmacological alternative to pharmaceutical pain relievers and anxiety medications in clinical trials by decreasing pain and anxiety in orthopedic surgeries. The aim of the study was to evaluate the impact of VR on these outcomes in individuals undergoing total hip arthroplasty (THA).
Methods: This randomized, controlled, open-label research included 50 participants planned for THA with spinal anesthesia (SA).

Duchenne muscular dystrophy (DMD) is a severe, progressive genetic disorder caused by mutations in the DMD gene, resulting in the absence of dystrophin-a key structural protein at the sarcolemma. As the disease progresses, cardiac involvement becomes a leading cause of morbidity and mortality. By adolescence or early adulthood, many patients develop dilated cardiomyopathy and arrhythmias.

Background: Polygenic risk scores (PRS) are not yet standard in clinical risk assessments for familial breast cancer in Sweden. This study evaluated the distribution and impact of an established PRS (PRS) in women undergoing clinical sequencing for hereditary breast cancer.
Findings: We integrated PRS into a hereditary breast cancer gene panel used in clinical practice and calculated scores for 262 women.
A Prediction Model for Obstructive Sleep Apnea in Bariatric Surgery Candidates with Obesity.

Department of Surgery, Tongji Hospital of Tongji University, Shanghai, China.
Background: Our study aimed to develop a predictive model for the risk of obstructive sleep apnea (OSA) in bariatric surgery candidates for utilization during the preoperative evaluation.
Methods: Relevant clinical data were retrospectively collected for 453 patients who met the inclusion criteria and did not meet the exclusion criteria; the patients were randomized into training and test cohorts. Univariate analysis was performed on the training set.
Safety and Efficacy of Intracranial Stenting in Acute Stroke Patients Using a Pharmacological Treatment Protocol Including Low-Dose Intra-arterial Eptifibatide-A Single-center Retrospective Analysis.

Department of Neurology, Soroka Medical Center, Beer Sheva, Israel.
Purpose: Emergent intracranial stenting (EICS) has demonstrated efficacy in managing intracranial stenosis in patients undergoing mechanical thrombectomy (MT) for acute ischemic stroke. However, an optimal pharmacological regimen balancing thrombosis prevention and hemorrhagic risk following stent deployment remains undefined. This study aimed to assess the safety and efficacy of prophylactic low-dose intra-arterial Eptifibatide following EICS.
