Article Abstract
Prognostic factors for high-grade gliomas include patient age, IDH1 mutation, MGMT methylation, and Ki67 value. We assessed the predictive role of topographic location of gliomas for their biological signatures. Collecting all neuroradiological and histological data of patients with histologically proven HGG, we performed a retrospective monocentric study. A predictive value of frontal location for a lower Ki67 value (especially in the left hemisphere) and mutation of IDH1 (especially in the right hemisphere) was found. Temporal location was predictive for IDH1 wild-type. Involvement of the parietal lobe was found to be predictive of methylated MGMT, while insular lobe involvement predicted an unmethylated MGMT. There was no statistically significant difference of IDH1 mutation and MGMT methylation between left and right sides.

Background: Disparities in cancer burden between transgender and cisgender individuals remain an underexplored area of research.
Objective: This study aimed to examine the cumulative incidence and associated risk factors for cancer and precancerous conditions among transgender individuals compared with matched cisgender individuals.
Methods: We conducted a retrospective cohort study using patient-level electronic health record (EHR) data from the University of Florida Health Integrated Data Repository between 2012 and 2023.
Impact of Commercial Food Environments on Local Type 2 Diabetes Burden: Cross-Sectional and Ecological Multimodeling Study.
JMIR Public Health Surveill
September 2025

Background: Neighborhoods resulting from rapid urbanization processes are often saturated with eateries for local communities, potentially increasing exposure to unhealthy foods and creating diabetogenic residential habitats.
Objective: We examined the association between proximity of commercial food outlets to local neighborhood residences and type 2 diabetes (T2D) cases to explore how local T2D rates vary by location and provide policy-driven metrics to monitor food outlet density as a potential control for high local T2D rates.
Methods: This cross-sectional ecological study included 11,354 patients with active T2D aged ≥20 years geocoded using approximate neighborhood residence aggregated to area-level rates and counts by subdistricts (mukims) in Penang, northern Malaysia.
Robotic-Assisted Versus Manual Total Hip Arthroplasty Performed for Hip Dysplasia.

Introduction: Developmental dysplasia of the hip (DDH) poses challenges for component positioning during total hip arthroplasty (THA) secondary to abnormal bone morphology, soft-tissue contractures, and hip center migration. The objective of this study was to evaluate the radiographic and clinical outcomes of THA for DDH performed with robotic assistance versus manual (M) technique.
Methods: A retrospective review identified 115 patients with Crowe II to IV dysplasia undergoing primary THA at a single institution from 2016 to 2022.
Neuroimaging Findings in Children and Young Adults With Neurotoxicity After CAR T-Cell Therapy for B-Cell Malignancies.
Neurology

Norcliffe Foundation Center for Integrative Brain Research, Seattle Children's Research Institute, WA.
Background And Objectives: Neuroimaging findings in immune effector cell-associated neurotoxicity syndrome (ICANS) have not been systematically described. We created the chimeric antigen receptor (CAR) T-cell Neurotoxicity Imaging Virtual Archive Library (CARNIVAL), a centralized imaging database for children and young adults receiving CAR T-cell therapy. Objectives of this study were to (1) characterize neuroimaging findings associated with ICANS and (2) determine whether specific ICANS-related neuroimaging findings are associated with individual neurologic symptoms.

Background And Objectives: α-Synuclein seed amplification assays (αSAAs) can improve the diagnosis of synucleinopathies and detect α-synuclein (αSyn) copathology in vivo in clinical practice. We aimed to evaluate the diagnostic performance of αSAA for detecting αSyn in CSF for diagnosing dementia with Lewy bodies (DLB) in a clinical cohort of cognitively impaired individuals. We explored how the coexistence of Alzheimer disease (AD) and αSyn pathology influences biomarker levels and clinical profiles.
