AI Article Synopsis
- - The study examines the effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on recovery from acute skeletal muscle injuries, focusing on outcomes like strength loss, soreness, and blood creatine kinase levels.
- - A systematic review analyzed 41 studies out of 5343 screened reports, revealing that NSAID use resulted in a significant reduction in injury markers, with a positive effect size (ES = +0.34; P = .0001).
- - The findings indicate that NSAIDs can help improve recovery in humans after muscle injuries, though results varied depending on the type of muscle injured and duration of NSAID use, underscoring the need for further research.
Article Abstract
Background: There is debate as to whether the use of nonsteroidal anti-inflammatory drugs (NSAIDs) is beneficial after acute skeletal muscle injury. Some studies have suggested that NSAID use may be detrimental to injured muscle.
Purpose: To determine whether NSAID use affects recovery from skeletal muscle injury as assessed by strength loss, soreness, and/or blood creatine kinase level.
Study Design: Systematic review and meta-analysis.
Methods: An extensive systematic review was completed searching 16 databases (eg, PubMed, Cochrane Library, EMBASE). Inclusion criteria were (1) acute injury to skeletal muscle, (2) use of a control condition, (3) certainty of the NSAID dose administered, and (4) use of 1 or more of the 3 desired outcome measures. A total of 5343 study reports were screened, of which 41 studies were deemed suitable for inclusion. The standardized mean difference was used as the effect size (ES) and was calculated such that a positive ES indicated NSAID efficacy. Meta-analyses were run using a random-effects model.
Results: For all studies, time points after injury, and injury markers combined, NSAID use was found to elicit a small to medium, significant decrease in the markers of injury (overall ES = +0.34; P = .0001). Because heterogeneity in study ES was apparent (ie, Q- df = 52.4, P = .000005; I = 57%), subgroup meta-analyses and meta-regressions were run in an attempt to explain the heterogeneity. In human studies, study ESs were higher when lower body muscles were injured ( P = .045). In animal studies, study ESs were lower with longer NSAID administration durations ( P = .023) and at longer follow-up times after injury ( P = .010).
Conclusion: Overall, our analysis supports NSAID use for reducing strength loss, soreness, and blood creatine kinase level after an acute muscle injury, at least for humans and in the short term. Additional research is required to determine why NSAID use appears to be more effective when lower-body muscles in humans are injured. It would also be important to determine why NSAID use appears detrimental at later times after injury in animals but not humans.

Background: DNA methylation (DNAm) data from human samples has been leveraged to develop "epigenetic clock" algorithms that predict age and other aging-related phenotypes. Some DNAm clocks were trained using DNAm obtained from blood cells, while other clocks were trained using data from diverse tissue/cell types. To assess how DNAm clocks perform across non-blood tissue types, we applied DNAm algorithms to DNAm data generated from 9 different human tissue types.

Arthrogryposis multiplex congenita (AMC) is a heterogeneous disorder associated with 1/3000 to 1/5000 live births. We report a consanguineous family with multiple affected members with AMC and identified a recessive mutation in the highly conserved splice donor site, resulting in the mis-splicing of the affected exons. SENP7 is a deSUMOylase that is critical for sarcomere assembly and skeletal muscle contraction by regulating the transcriptional program in the skeletal muscle.

In vertebrates, skeletal muscle comprises fast and slow fibers. Slow and fast muscle cells in fish are spatially segregated; slow muscle cells are located only in a superficial region, and comprise a small fraction of the total muscle cell mass. Slow muscles support low-speed, low-force movements, while fast muscles are responsible for high-speed, high-force movements.

Objective: The objective of this study was to analyse the association between body composition and changes in health-related quality of life (HRQoL) of patients followed for hip and knee osteoarthritis (OA).
Methods: Longitudinal data from the Knee and Hip OsteoArthritis Long-term Assessments (KHOALA) cohort, a multicentre cohort of 878 patients with symptomatic knee and/or hip OA, were used. The main outcome criteria were changes in patient-reported outcomes measures, the Study Short Form-36 (physical functioning, pain, mental health and vitality) and the OsteoArthritis Knee and Hip Quality Of Life (OAKHQOL)(physical activity, pain and mental health).
Introduction And Importance: Neglected posterior hip dislocations in adults are rare, particularly when untreated for years. In developing nations, patients often rely on traditional bone setters, leading to delayed diagnosis and increased complications. Adult hip dislocations carry a higher risk of avascular necrosis and require complex treatments.
