Toward non-clinical validation of fractional flow reserve simulation software: A generic coronary artery geometry.

Medical image-based diagnostic techniques have become increasingly common in the clinic. Estimating fractional flow reserve in coronary stenoses from medical image data is among the most prominent examples. The modeling techniques used in these clinical tools require rigorous experimental validation yet there is currently no standardized, public toolset to help assess model credibility.

Trabecular Bone Score in Individuals with Chronic Spinal Cord Injury: A Cross-Sectional Study.

Objectives: To describe lumbar spine (LS) trabecular bone score (TBS) values after SCI, and to explore the differences in fractures risk assessment between FRAX® and TBS-adjusted FRAX® in individuals living with chronic SCI.

Methods: Baseline dual-energy x-ray absorptiometry (DXA) scans from an established cohort were acquired using a Hologic Discovery QDR 4500. TBS measurements were performed using the TBS iNsight software version 2.

Urban-Rural Disparities in Community Participation after Spinal Cord Injury in Ontario.

Background: Personal, social, and environmental factors may influence self-efficacy and social reintegration among people living with spinal cord injury or disease (SCI/D) in urban and rural areas. Novel data collection methods have the potential to characterize community participation (CP) in diverse settings.

Objectives: The objectives were (1) to describe and compare self-reported community participation (Reintegration to Normal Living Index (RNLI) and Moorong Self-Efficacy Scale (MSES)) levels of individuals with SCI/D living in urban or rural Ontario, Canada; and (2) to determine the accuracy of an artificial intelligence (AI) optical mark recognition tool for extracting data from CP surveys conducted among participants after transitioning from inpatient rehabilitation to home and residing in the community.

COVID-19 and Mortality in the Spinal Cord Injury Population: Examining the Impact of Sex, Mental Health, and Injury Etiology.

Background/objective: The purpose of this study was to investigate the impact of the COVID-19 pandemic on mortality rates in a community-dwelling spinal cord injury (SCI) population in Ontario.

Methods: Using health administrative databases, monthly mortality rates were evaluated pre-pandemic, during the pandemic, and post-pandemic from March 2014 to May 2024. Data were stratified by sex, injury etiology, and mental health status.
