Article Abstract
Purpose: We aimed to examine the regional disparities in secondary fracture incidence among patients with hip fractures in South Korea.
Methods: This observational, retrospective, cohort study was conducted using data of 6,213 South Korean nationals from the National Health Insurance Service-National Sample Cohort (2004-2019). Secondary fractures included hip, wrist, humerus, spine, ankle, and pelvis fractures that occurred 6 months after hip fracture. The position value for relative composite index was used to identify medically vulnerable regions. Cox proportional hazards models were used for statistical analysis.
Results: Among the 6,213 (1,949 male, 4,264 female) patients with hip fracture, 981 lived in medically vulnerable areas and 5,232 in non-vulnerable areas. Patients residing in vulnerable areas had a higher risk of secondary fractures than did those residing in non-vulnerable areas (hazard ratio [HR]: 1.24, 95 % confidence interval [CI]: 1.05-1.47); the factors that increased their risk included female sex (HR: 1.30, 95 % CI: 1.08-1.57), age ≥71 years (HR: 1.23, 95 % CI: 1.01-1.44), and not receiving osteoporosis medication (HR: 1.47, 95 % CI: 1.14-1.89). Ten years after hip fracture surgery, the risk of secondary fracture more than tripled in the vulnerable areas than that in the non-vulnerable areas.
Conclusion: Patients living in vulnerable regions had a higher risk of secondary fractures than that of those in non-vulnerable regions. Prevention and medication policies should thus be implemented to reduce regional healthcare disparities.

Prevention of Incisional Hernias With Prophylactic Synthetic Mesh Placement During Stoma Reversal: A Randomized Clinical Trial.
JAMA Surg
September 2025
Department of Surgery, Meander Medical Center, Amersfoort, the Netherlands.
Importance: Stoma reversal is associated with few complications. However, recent studies show that 1 in 3 patients develop an incisional hernia, for which half of the patients receive surgical correction.
Objective: To investigate whether prophylactic synthetic mesh placement in the retromuscular space during stoma reversal reduces the rate of stomal site incisional hernias.
Do psycho-behavioural interventions improve mental and physical health in chronic kidney disease? A systematic review of randomised controlled trials.

Background: Depression and anxiety are common in chronic kidney disease (CKD) and worsen clinical outcomes. Psycho-behavioural interventions offer a promising, non-pharmacological approach. However, most evidence comes from people with kidney failure with distinct treatment needs, limiting relevance to earlier stages of CKD, where timely support may enhance self-management and slow progression.

School of Public Health Sciences, University of Waterloo, Waterloo, Canada.
Purpose: Sleep disturbance is prevalent in long-term care facilities (LTCFs), yet there is limited understanding of individual factors predicting changes in sleep within these populations. Our objective was to determine predictors of sleep disturbance in LTCFs and investigate variation in prevalence across facilities in two Canadian provinces-New Brunswick and Saskatchewan.
Method: This retrospective longitudinal cohort study used interRAI comprehensive health assessment data from 2016 to 2021, encompassing 21,394 older adults aged ≥ 65 years across 228 LTCFs.
Do generic population utility scores accurately represent real-world experienced health?
Qual Life Res

School of Pharmacy, CHOICE Institute, University of Washington, 1956 NE Pacific St H362, Seattle, WA, 98195, USA.
Purpose: Typically, cost-effectiveness analyses use societal utility weights for health states. These anticipated utility weights are derived from asking the general population to assess the impacts of hypothetical health states on their quality-of-life. This study evaluates how these weights align with real-world self-reported experienced health statuses.

External exposure due to secondary photons (predominantly bremsstrahlung) generated from electron source emissions in environmental soil are of concern due to their ability to deposit significant amounts of ionizing energy to organs and tissues within the body. The "condensed history method" employed in many modern Monte Carlo (MC) codes may be used to simulate secondary photon yields (given as photons per beta decay) arising from electron source emissions with relatively few assumptions regarding the secondary photon spatial, energy, and angular dependencies. These yields may in turn be used to derive protection quantities such as secondary photon effective dose rate (DR) and risk coefficients for a variety of idealized external exposure scenarios.
