Article Abstract
Objectives: To examine whether social participation affects the association between frailty and disability.
Methods: A baseline survey conducted from December 1 to 15, 2006, included 11,992 participants who were classified based on the Kihon Checklist into three categories and based on the number of activities in which they socially participated into four categories. The study outcome, incident functional disability, was defined as in Long-Term Care Insurance certification. A Cox proportional hazards model was used to calculate hazard ratios (HRs) for incident functional disability according to frailty and social participation categories. Combination analysis was performed between the nine groups using the above-mentioned Cox proportional hazards model.
Results: During the 13-year follow-up (107,170 person-years), 5,732 incident cases of functional disability were certified. Compared with the robust group, the other groups had significantly higher incident functional disability. However, the HRs for those participating in social activities were lower than that for those not participating in any activity [1.52 (pre-frail + none group); 1.31 (pre-frail + one activity group); 1.42 (pre-frail + two activities group); 1.37 (pre-frail + three activities group); 2.35 (frail + none group); 1.87 (frail + one activity group); 1.85 (frail + two activities group); and 1.71 (frail + three activities group)].
Conclusions: The risk of functional disability for those participating in social activities was lower than that for those not participating in any activity, irrespective of being pre-frail or frail. Comprehensive social systems for disability prevention need to focus on social participation in frail older adults.

The etiology of uveitis, choroid inflammation, is diverse, the disease is often recurrent, difficult to treat, and frequently results in disability at a young age. Studies investigating the tear fluid composition in uveitis have revealed promising biomarkers relevant for prognosis and treatment optimization. This review presents literature data on changes in the tear fluid content of proteins involved in local immune responses, intercellular interactions, proteolytic and free radical processes, nitric oxide metabolism, and other metabolic pathways in different forms of uveitis.

Processing delays can negatively affect listening experience, especially in cases where the (processed) delayed sound interferes with an un-delayed (or direct) sound component, as it is the case for (open-fit) hearing devices. In this study, psychometric functions for delay perception in individual frequency bands were measured. Also, it was assessed how noticeability adds up across frequency bands for frequency-dependent processing delays.

Musculoskeletal disorders, including bone fractures, osteoarthritis, and muscle injuries, represent a leading cause of global disability, revealing the urgency for advanced therapeutic solutions. However, current therapies face limitations including donor-site morbidity, immune rejection, and inadequate mimicry of dynamic tissue repair processes. DNA-based hydrogels emerge as transformative platforms for musculoskeletal reconstruction, with their sequence programmability, dynamic adaptability, and biocompatibility to balance structural support and biological functions.

Background And Purpose: Ciprofol, a novel intravenous anesthetic, has been shown to exert protective effects against ischemic stroke, a leading cause of death and disability; however, its molecular mechanisms remain unclear. This study aimed to explore the molecular mechanisms underlying the neuroprotective effects of ciprofol using metabolomics.
Methods: This study used a middle cerebral artery occlusion (MCAO) rat model to simulate cerebral ischemia-reperfusion injury (CIRI).

Background: In the clinical practice of Korean Medicine, pharmacopuncture therapy and acupotomy (PA) are being increasingly explored as potential treatment options for degenerative lumbar spinal stenosis (LSS). In this study, we aimed to evaluate the effectiveness and safety of combining PA with conventional Korean Medicine treatment (CKMT) in patients with degenerative LSS.
Methods: A pragmatic, assessor-blinded, randomized controlled trial was conducted with 104 participants aged 40-75 years diagnosed with degenerative LSS.
