Is Appendicular Lean Soft Tissue Mass a Clinically Valid Diagnostic Marker for Sarcopenia?

<p><b>AIM</b></p><p>Geriatric experts have long debated the inclusion of appendicular lean soft tissue mass (ALSTM) in the diagnostic criteria for sarcopenia. This study examined whether a diagnostic model for sarcopenia that excludes appendicular lean soft tissue mass (ALSTM) is equivalent to...

Rethinking Muscle Aging Through the Lens of Fibro-Adipogenic Progenitors.

Aging of skeletal muscles is accompanied by a progressive deposition of adipose and fibrotic tissue within the interstitial compartment. This process profoundly disrupts the structural integrity and contractile function of the muscle. Such maladaptive remodeling not only compromises muscle performance...

Therapeutic potential of FGF19 in combatting osteosarcopenia: effects on muscle strength and bone health in aged male mice.

Osteosarcopenia, characterized by the coexistence of osteopenia/osteoporosis and sarcopenia, represents a significant health concern in geriatrics, with an increased risk of falls and fractures. The enterokine fibroblast growth factor 19 (FGF19) was recently shown to prevent muscle weakness in preclinical...

Jianpi Qiangji Granule ameliorates aging-associated sarcopenia via AMPK/PGC-1ฮฑ axis in SAMP8 mice.

<p><b>BACKGROUND</b></p><p>Sarcopenia is an age-related syndrome characterized primarily by the progressive decline of muscle mass and function. It is frequently associated with adverse outcomes such as falls, fractures, and hospitalization, often leading to substantial economic burdens and severe health hazards. At...

PRDX5 Regulates Mitochondrial Function and Nuclear Spreading in Myogenesis and Acts With PRDX3 to Delay Muscle Aging.

<p><b>BACKGROUND</b></p><p>Skeletal muscle aging is associated with oxidative stress and mitochondrial dysfunction. Peroxiredoxins (PRDXs), particularly PRDX3 and PRDX5, are antioxidant enzymes that are uniquely localized to mitochondria. While PRDX3 has been reported to play a role in maintaining mitochondrial function in...

Implementation of blood flow restriction training in the acute geriatric unit.

<p><b>BACKGROUND</b></p><p>Hospital-associated physical decline is common among older adults. High-load training mitigates this but, is often impractical in acute care settings. Blood flow restriction (BFR) training is a promising low-load alternative, yet clinical utility during hospitalisation is unclear.</p><p><b>OBJECTIVE</b></p><p>To evaluate feasibility, safety...

Advancing Single-Cell Transcriptomic Analysis to Reveal Age-Related Skeletal Muscle Changes: A Systematic Review.

Population aging has become a widespread health problem that leads to huge socioeconomic burden. Skeletal muscle as an important component of motor system, gradually degenerates with age. Age-related muscle disorders, such as sarcopenia is associated with higher risks of falls,...

Microenvironment-driven satellite cell regeneration and repair in aging-related sarcopenia: mechanisms and therapeutic frontiers.

Sarcopenia, a progressive age-related decline in skeletal muscle mass and function, is closely linked to impaired regenerative capacity of satellite cells (SCs), also known as satellite cells.

Muscle-Specific Strength Better Predicts Physical Performance Decline Than Conventional Metrics: The I-Lan Longitudinal Aging Study.

Muscle-specific strength (MSS), defined as grip strength normalized to arm muscle mass, may better reflect muscle efficiency than grip strength.
