Skeletal muscle aging is a major cause of frailty, metabolic dysfunction, and loss of independence in later life, yet it cannot be explained by muscle mass loss alone. Recent single-cell, multi-omics, and translational studies show that aged muscle is shaped...
BACKGROUND
Malnutrition and muscle weakness are critical prognostic factors for mortality in older adults. While indices like the Geriatric Nutritional Risk Index (GNRI) are well-established, the long-term prognostic value of integrating nutrition with muscle strength (MS) remains insufficiently established in community-dwelling...
Aging, characterized by progressive physiological decline and systemic dysfunction, represents a major risk factor for age-related diseases such as sarcopenia, which involves fibrosis that disrupts muscle regeneration and function. Effective therapeutic strategies remain limited. Here we report UA-30, a novel...
BACKGROUND
Quantitative muscle MRI is increasingly used to assess structural muscle damage in inherited myopathies, but its application in primary mitochondrial myopathies (PMM) has not been systematically evaluated in large cohorts. Because PMM are clinically and genetically heterogeneous, objective imaging biomarkers...
OBJECTIVE
To investigate the potential of integrating muscle and fat compartments into a novel and unified score for outcome prediction in a bicentric European cohort of LT recipients.
BACKGROUND
Body composition (BC) reflects nutritional status and metabolic reserves and influences outcomes after orthotopic...
UNLABELLED
Cancer cachexia is a devastating wasting syndrome with no approved therapies. In this study, we identify the tumor-derived glycoprotein ADAMTSL4 as a circulating factor associated with body weight loss in preclinical cachexia models and patients with colorectal and lung cancers....
BACKGROUND
Skeletal muscle injuries significantly impair mobility and function, yet effective therapeutic interventions remain limited. Both eccentric exercise (EE) and concentric exercise (CE) promote muscle repair, but the underlying mechanisms are not fully understood. Muscle-derived extracellular vesicles (mEVs) have emerged as...
BACKGROUND
Ultra-endurance sports are increasingly popular, yet the long-term physiological consequences of sustained extreme training loads remain poorly understood. In particular, the effects of prolonged ultra-endurance exercise on skeletal muscle structure, function and molecular remodelling are largely unknown. This case study...
Sarcopenia is an age-related pathological syndrome characterized by progressive and generalized loss of skeletal muscle mass and function, with muscle atrophy representing its cardinal pathological hallmark. Ferroptosis, an iron-dependent regulated cell death, has been implicated in the pathogenesis of muscle...
BACKGROUND
Sarcopenia is highly prevalent in decompensated cirrhosis and independently predicts adverse outcomes. Although nutritional therapy is guideline-recommended, evidence comparing specialist dietitian-supervised nutritional care with routine physician-delivered dietary advice remains limited.
AIM
To compare the efficacy of dietitian-supervised intensive nutritional therapy with physician-led...
In mammals, nearly every cell contains an intrinsic circadian clock that functions both as a timekeeping system and an environmental sensor, integrating external cues to maintain alignment between internal physiology and the external environment. While the core clock machinery is...
Cancer-associated cachexia (CAC) is a multifactorial syndrome characterized by systemic inflammation, muscle wasting, and progressive functional decline, affecting up to 80% of patients with advanced cancer. The inconsistent diagnostic criteria limit comparability across studies and hinder translation into clinical practice....
Intermuscular adipose tissue (IMAT) refers to adipose tissue located between muscle groups or beneath the muscle fascia, and its accumulation is closely linked to impaired muscle quality, reduced contractile function, and adverse metabolic profiles, establishing it as a core component...
Cancer cachexia, affecting up to 80% of patients with advanced cancer, is characterized by metabolic and inflammatory dysregulation driven by tumour- and host-derived factors. Although cytokines are central to cachexia pathogenesis, their circulating profiles and transcriptional relevance across models and...
