Article Abstract
Aims: We aimed to establish sex-specific predictors for 1-year VT recurrence and 1-year all-cause mortality in patients with structural heart disease undergoing catheter ablation.
Methods: We analyzed data of 299 patients recorded in our structured registry. These included medical history, echocardiography parameters, laboratory results, VT properties, procedural data.
Results: Out of the 299 patients, 34 (11%) were female. No significant difference was found between women and men in terms of VT recurrence ( = 0.74) or mortality ( = 0.07). In females, severe mitral regurgitation (MR), tricuspid regurgitation (TR), presentation with incessant VT, and preprocedural electrical storm (ES) were associated with increased risk of VT recurrence. Diabetes, implanted CRT, VT with hemodynamic instability, ES and advanced MR were the risk factors of mortality in women. ACEi/ARB use predicted a favorable outcome in both endpoints among females. In men, independent predictors of VT recurrence were the composite parameter of ES and multiple ICD therapies, presentation with incessant VT, severe MR, while independent predictors of mortality were age, LVEF, creatinine and previously implanted CRT.
Conclusion: According to our investigation, there are pronounced sex differences in predictors of recurrence and mortality following VT ablation.

A Systematic Literature Review of Preference Studies in Migraine Treatments.

PPD Evidera Patient-Centered Research, Thermo Fisher Scientific, Waltham, MA, USA.
Background: Migraine care is often suboptimal owing to undertreatment, variation in clinical outcomes and administration methods among existing treatments, and between- and within-individual heterogeneity in the clinical course of migraine. In response to these challenges, preference studies have been increasingly conducted to inform treatment decision-making and development. However, gaps remain in understanding how treatment preferences have been assessed across different migraine studies.

Purpose: Living donor kidney transplantation is a critical strategy to address the growing burden of end-stage kidney disease (ESKD) in Malaysia. Whilst living donation is generally safe, concerns remain regarding long-term donor outcomes. This study aimed to evaluate renal function and morbidity changes in living kidney donors 1 year post-donation, and to identify predictors of impaired kidney function.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by complex disturbances in both innate and adaptive immune responses, often leading to multi-organ involvement. One of the key features of SLE pathogenesis is endothelial dysfunction, which contributes to immune cell infiltration and vascular inflammation. In this context, adhesion molecules such as platelet endothelial cell adhesion molecule-1 (PECAM-1), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) may reflect the degree of endothelial activation.

Objectives: The escalating global incidence of obesity, cardiometabolic disease and sarcopenia necessitates reliable body composition measurement tools. MRI-based assessment is the gold standard, with utility in both clinical and drug trial settings. This study aims to validate a new automated volumetric MRI method by comparing with manual ground truth, prior volumetric measurements, and against a new method for semi-automated single-slice area measurements.

Background: Comorbidities may affect incidence and management of cancers. The burden of comorbidities among AIAN cancer patients and survivors is unknown.
Methods: Using SEER-Medicare, we identified AIAN people aged 66+ years diagnosed with female breast, lung, and colorectal cancers (2000-2019), with at least one year of Medicare coverage prior to diagnosis.
