Cancer is frequently accompanied by cachexia, a systemic syndrome characterized by progressive loss of skeletal muscle mass, with or without loss of fat mass. Increasing evidence indicates that cancer can also induce cardiac muscle wasting, which is associated with structural...
The early screening of sarcopenia represents a critical clinical need amid the accelerating global aging population. Current diagnostic methods, relying on bioelectrical impedance analysis (BIA), handgrip strength testing, and other clinical examinations, depend on costly medical equipment and struggle to...
BACKGROUND
Metabolic and bariatric surgery (MBS) produces substantial and sustained weight loss, but concerns remain about skeletal muscle loss and sarcopenia.
METHODS
We conducted a systematic review of longitudinal and cross-sectional studies evaluating changes in muscle quantity, strength, and physical performance following MBS...
BACKGROUND
Ageing is an inevitable biological process that contributes to increased prevalence of age-associated diseases, including sarcopenia, defined by progressive loss of muscle mass, functional decline and a heightened risk of injury. Developing effective interventions remains a critical clinical priority. This...
Skeletal muscle mass and force decline with age, and the loss of muscle force precedes muscle atrophy. However, the underlying mechanisms remain unclear. Here, we investigated the role of the myosin co-chaperone, uncoordinated mutant number-45 myosin chaperone B (UNC45B), in...
BACKGROUND
Resistance training benefits patients with sarcopenia. However, trials demonstrating the effectiveness of Tai Chi combined with elastic band training are sparse, and the underlying neurocognitive mechanisms remain unclear.
METHODS
Forty-nine older sarcopenia patients (≥60 years) were recruited and randomly assigned to three groups:...
BACKGROUND
Longitudinal associations between age-related changes in body composition, physical performance and incident diabetes mellitus (DM) in older adults and the mediating role of branched-chain amino acids (BCAAs) remain understudied.
METHODS
This prospective cohort study included 4000 community-dwelling older adults at baseline. Longitudinal...
BACKGROUND
Sarcopenic obesity (SO) is well-characterized in older adults, but its impact on muscle development in children remains poorly understood. This study investigated the effects of childhood obesity on musculoskeletal health and the underlying mechanisms.
METHODS
We enrolled 1447 children (31.4% girls; median...
Skeletal muscle accounts for approximately 40% of total body mass and is essential for locomotion, metabolic regulation and systemic homeostasis. Adipose tissue is increasingly recognized as an active component of the muscle's regenerative microenvironment. During muscle repair, adipose tissue contributes...
Sarcopenic obesity (SO; defined as obesity with low skeletal muscle function and mass) has been recently recognized as a relevant obesity phenotype, with substantial negative clinical impact. The prevalence of SO is likely increasing, due to the growing prevalence of...
Sarcopenia is characterized by age-related declines in muscle strength and mass, along with impaired physical function. It remains an unmet medical need, and there are no pharmacological interventions approved for this indication. The activation of growth hormone secretagogue receptor (GHSR)-1a,...
BACKGROUND
Exercise has been proposed as both a preventive and therapeutic countermeasure; however, its effectiveness across different disuse conditions and timings of implementation remains uncertain.
METHODS
This systematic review and meta-analysis (PROSPERO: CRD42021256599) searched ClinicalTrials.gov, Cochrane Central, PubMed, SPORTDiscus, Web of Science, Scopus,...
BACKGROUND
Diabetes mellitus-a chronic metabolic disorder associated with an increased risk of muscle atrophy-can significantly impact patients' quality of life and overall health outcomes. While antidiabetic medications are crucial for managing blood glucose levels, some have been linked to muscle-related adverse...
BACKGROUND
Sepsis-induced myopathy (SIM) is a severe complication that contributes to late-stage mortality and functional impairment in sepsis patients. The NLRP3 inflammasome plays a pivotal role in the pathogenesis of SIM, and its selective inhibitor MCC950 has shown promising therapeutic potential....
