AI Article Synopsis
- The study analyzed data from over 218,000 participants in the World Health Survey to compare disability prevalence and wealth-related inequalities across various countries.
- Findings revealed that disability was more common in low-income countries and among poorer individuals in all countries, with significant pro-rich inequality observed in 43 out of 49 countries.
- The researchers emphasized the importance of including equity considerations in monitoring disability trends to ensure effective interventions for the most disadvantaged populations.
Article Abstract
Objectives: We compared national prevalence and wealth-related inequality in disability across a large number of countries from all income groups.
Methods: Data on 218,737 respondents participating in the World Health Survey 2002-2004 were analyzed. A composite disability score (0-100) identified respondents who experienced significant disability in physical, mental, and social functioning irrespective of their underlying health condition. Disabled persons had disability composite scores above 40. Wealth was evaluated using an index of economic status in households based on ownership of selected assets. Socioeconomic inequalities were measured using the slope index of inequality and the relative index of inequality.
Results: Median age-standardized disability prevalence was higher in the low- and lower middle-income countries. In all the study countries, disability was more prevalent in the poorest than in the richest wealth quintiles. Pro-rich inequality was statistically significant in 43 of 49 countries, with disability prevalence higher among populations with lower wealth. Median relative inequality was higher in the high- and upper middle-income countries.
Conclusions: Integrating equity components into the monitoring of disability trends would help ensure that interventions reach and benefit populations with greatest need.

Background: The utility of aging metrics that incorporate cognitive and physical function is not fully understood.
Objective: We aim to compare the predictive capacities of 3 distinct aging metrics-motoric cognitive risk syndrome (MCR), physio-cognitive decline syndrome (PCDS), and cognitive frailty (CF)-for incident dementia and all-cause mortality among community-dwelling older adults.
Methods: We used longitudinal data from waves 10-15 of the Health and Retirement Study.
Long-Term Treatment With Ocrelizumab in Patients With Early-Stage Relapsing MS: Nine-Year Data From the OPERA Studies Open-Label Extension.

Background And Objectives: Patients with multiple sclerosis (MS) may demonstrate better disease control when treatment is initiated on high-efficacy disease-modifying therapies (DMTs) from onset. This subgroup analysis assessed the long-term efficacy and safety profile of the high-efficacy DMT ocrelizumab (OCR) as first-line therapy for early-stage relapsing MS (RMS).
Methods: Post hoc exploratory analyses of efficacy and safety were performed in a subgroup of treatment-naive patients with RMS who received ≥1 dose of OCR in the multicenter OPERA I/II (NCT01247324/NCT01412333) studies.
Advances in clinical translation of stem cell-based therapy in neurological diseases.

Stem cell-based therapies have raised considerable interest to develop regenerative treatment for neurological disorders with high disability. In this review, we focus on recent preclinical and clinical evidence of stem cell therapy in the treatment of degenerative neurological diseases and discuss different cell types, delivery routes and biodistribution of stem cell therapy. In addition, recent advances of mechanistic insights of stem cell therapy, including functional replacement by exogenous cells, immunomodulation and paracrine effects of stem cell therapies are also demonstrated.

Early repair of flexor tendon injuries is ideal, but delays are common. We studied the outcomes of flexor tendon repairs delayed from 5 days to 6 months and carried out under wide-awake local anaesthesia with no tourniquet (WALANT). Twenty-four patients (29 fingers) who underwent primary flexor tendon repair on zone II using a four- to six-strand core suture technique, followed by controlled early active motion therapy.

The association of muscle weakness with poor outcomes is well defined in general older population, but there is insufficient data on the association of muscle weakness with functionality in older patients with diabetes mellitus (DM). We aimed to investigate the predictivity of muscle weakness defined as low grip strength thresholds determined by EWGSOP2, and two regional thresholds in older patients with DM for functional disability. Activities of Daily Living (ADL), Instrumental ADL (IADL), grip strength, comorbidities, anthropometric and biochemical data from outpatient clinic medical records were screened retrospectively.
