Sarcopenia
Creatine/Creatinine Ratio and Myostatin as Biomarkers to Monitor Muscle Function in Duchenne Muscular Dystrophy Patients.
BACKGROUND
Duchenne Muscular Dystrophy (DMD) is characterized by progressive muscle wasting leading to early loss of motor function. Functional tests monitor disease progression and serve as clinical trial endpoints but are influenced by maturation in younger patients, high intra-patient variability and...
Hepatokines lipocalin 2 and osteopontin drive muscle atrophy in MASH.
A bidirectional relationship exists between metabolic dysfunction-associated steatotic liver disease (MASLD) and its progressive inflammatory form, metabolic dysfunction-associated steatohepatitis (MASH), and sarcopenia, with each worsening the prevalence and prognosis of the other. Hepatokines have recently been shown to affect skeletal...
Endocannabinoid system and skeletal muscle health: insights from cannabidiol.
The endocannabinoid (EC) system is a complex network comprising endogenous ligands, enzymes responsible for their synthesis and degradation, and various receptors (including CB1 and CB2). Present in many peripheral tissues, including skeletal muscle, EC system is now recognized to influence...
Lowered Abundance of Gut Bacteriophage Species Is Associated With Human Cancer Cachexia.
BACKGROUND
Cancer cachexia exemplifies a high medical need condition without effective treatment. Recent studies implicated bacterial gut microbiome alterations to cancer cachexia. Whether the gut bacteriophage profile, an important microbiome component for health and disease, is also related to cancer cachexia...
Sarcopenic obesity and dementia risk: Primary associations and landmark analyses of muscle strength and body composition trajectories.
BACKGROUND AND AIMS
Sarcopenic obesity (SO) has been proposed as a risk factor for cognitive impairment. Yet evidence is inconsistent and often limited by heterogeneous definitions and lack of longitudinal assessments. This study aimed to examine associations of SO with all-cause...
Muscle-Adipose Aging Dynamics and Inflammaging Patterns Across Ethnically Diverse Populations: Exploring Potential Roles of Lipolysis.
BACKGROUND
Muscle-adipose aging reflects interactions between body composition changes and chronic inflammatory processes, but age-related patterns in these measures across ethnically diverse populations remain incompletely described. Understanding population-specific patterns is crucial for developing tailored prevention and intervention strategies. We aimed to...
Positive allosteric modulator selective for adult muscle nicotinic acetylcholine receptor.
The muscle nicotinic acetylcholine receptor (AChR) is the key mediator of neuromuscular signal transmission and is essential for all voluntary movement in our body. In this study, we present DC-98-LC74, a positive allosteric modulator (PAM) for the adult skeletal muscle-type...
Novel Long-Acting Ghrelin Analogue PEP-064 Restores Energy Balance in C26 and Lewis Lung Carcinoma-Induced cachexia in Mice.
BACKGROUND
Cancer cachexia is a debilitating syndrome marked by involuntary weight loss resulting from reduced food intake and intricate metabolic reprogramming. Despite its high prevalence, cancer cachexia remains undertreated, with a lack of effective and approved pharmacotherapies. Ghrelin has emerged as...
Longitudinal Assessment of Muscle Involvement in Late-Onset Pompe Disease Using Quantitative MRI: A Prospective Cohort Study.
BACKGROUND
Late-onset Pompe disease (LOPD) is a progressive metabolic myopathy characterised by lysosomal glycogen accumulation and leading to secondary disruptions in autophagy and cellular energy metabolism. While enzyme replacement therapy (ERT) has improved outcomes, early detection remains critical, because irreversible muscle...
Sema4A Protects Against Muscle Atrophy and Promotes Repair by Regulating Intracellular Metabolic Signalling.
BACKGROUND
Skeletal muscle atrophy is a debilitating condition associated with diverse diseases and clinical interventions. Although triggers such as glucocorticoid excess or direct muscle injury disrupt the balance between protein homeostasis and tissue repair, the upstream molecular signals that actively preserve...
Handgrip Strength Thresholds to Detect Cardiometabolic Risk in Youth: Cross-Sectional Study and Meta-Analysis.
BACKGROUND
Muscular fitness, particularly handgrip strength, is increasingly recognized as a robust marker of cardiometabolic risk (CMR) in children and adolescents. However, evidence-based diagnostic thresholds for identifying at-risk individuals remain scarce, particularly in children. This study aimed to (1) establish sex-specific...
Combined Bisoprolol and Megestrol Acetate Improves Survival and Preserves Cardiac Performance in a Rat Model of Cancer Cachexia.
BACKGROUND
Cancer cachexia is associated with rapid body wasting and cardiac dysfunction. Bisoprolol (BIS) and megestrol acetate (MA) improve selected cachexia phenotypes in the Yoshida AH-130 model, but their combined effects are not defined. We tested reduced-dose combined treatment of BIS...
Food-derived bioactive peptides in gut-muscle Axis regulation: Potential and challenges from microbiota homeostasis to muscle metabolism remodeling.
The global population is aging at an accelerating pace, and sarcopenia has emerged as a central challenge to elderly health. Food-derived bioactive peptides, as natural functional compounds, can interact significantly with the gut microbiota, thereby indirectly influencing muscle metabolism and...
Automated abdominal aortic calcification, muscle health and incident falls: the UK Biobank Imaging Study.
Emerging evidence suggests that vascular disease is linked with poorer muscle strength and higher falls risk. We evaluated the association between abdominal aortic calcification (AAC), scored using a well-established and validated 24-point machine learning algorithm (ML-AAC24), with magnetic resonance imaging-derived...
From Pixels to Prediction: Reviewing the Role of Artificial Intelligence in Body Composition Analysis.
Evaluation of body composition (BC) is a set of biomarkers, including fat, muscle and bone, that allows the quantification of an individual's composition at different levels of complexity (whole body, tissues, macroscopic and microscopic). Recently, BC has gained medical interest...
