BACKGROUND
Sarcopenia, an age-related loss of skeletal muscle strength, mass and function, is linked with dementia and Alzheimer's disease (AD). Current guideline-recommended tools to diagnose sarcopenia, such as appendicular skeletal muscle mass (ASM), calculated as the sum of lean muscle mass...
Role of Peptides in Skeletal Muscle Wasting: A Scoping Review.
BACKGROUND
Systemic muscle wasting is a prevalent condition that predicts adverse health outcomes in aging and disease. Despite its clinical relevance, the development of predictive biomarkers and effective pharmacological therapies remains limited. Peptides have recently gained attention for their diverse bioactive...
Integrating genetics and transcriptome analyses identify potential biomarkers and immune interactions in metabolic syndrome-related sarcopenia.
BACKGROUND
Increasing evidence has indicated that metabolic syndrome (MetS) exists in a close link with sarcopenia; however, the potential mechanism and biomarkers between them remain uninvestigated. This study leverages integrative genetics and transcriptome to identify potential biomarkers and immune interactions in...
Cachexia in Pancreatic Cancer: New Insights to Impact Quality of Life and Survival.
Introduction: Cancer cachexia is associated with systemic inflammation and metabolic derangement, leading to muscle atrophy, which affects over 80% of pancreatic cancer patients, the highest rate among all malignancies, negatively impacting quality of life and significantly reducing survival rate. Malnutrition,...
Adipose-tumor crosstalk in colorectal cancer: Identifying (Epi)genetic biomarkers for tumor progression and cachexia.
Colorectal cancer (CRC) is a leading cause of cancer-related deaths and obesity is a known risk factor for its development and poor prognosis. Adipose tissue (AT) actively contributes to CRC progression and cachexia. Here, we investigated molecular crosstalk between tumor...
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. Despite its potential utility in diagnosing sarcopenia, longitudinal studies evaluating MSS as a predictor of sarcopenia-related outcomes remain limited. This...
Exploration of Fully-Automated Body Composition Analysis Using Routine CT-Staging of Lung Cancer Patients for Survival Prognosis.
AI-driven automated body composition analysis (BCA) may provide quantitative prognostic biomarkers derived from routine staging CTs. This two-centre study evaluates the prognostic value of these volumetric markers for overall survival in lung cancer patients. Lung cancer cohorts from Hospital A...
Elevated Serum Gamma-Glutamyl Transferase as a Risk Factor for Frailty in Older Men: A Nationwide Population-Based Study.
Oxidative stress is a key driver of accelerated ageing, and gamma-glutamyl transferase (GGT), an essential enzyme involved in the metabolism of glutathione, a major antioxidant, plays a pivotal role in the generation of free radical species. This study aimed to...
Circulating miR-144-3p as a Novel Independent Biomarker Associated With Low Muscle Strength Among Older Adults.
Low muscle strength, a key component of sarcopenia, is significant in the development of adverse health outcomes among older adults. MicroRNAs (miRNAs) have been implicated in mechanisms of sarcopenia; however, their specific functions in sarcopenia components, particularly low muscle strength,...
GDF15: from biomarker to target in cancer cachexia.
Most patients with advanced cancer suffer from cachexia, a complex metabolic disorder characterized by unintentional body weight loss that diminishes their quality of life and reduces the effectiveness of therapies. Currently, effective treatments for cachexia remain elusive. Growth differentiation factor...
Therapeutic advances in sarcopenia management: From traditional interventions to personalized medicine.
Sarcopenia, a progressive decline in skeletal muscle mass and function, has emerged as a critical geriatric syndrome affecting 10-40% of older adults, contributing to increased disability and mortality. This comprehensive review evaluates evidence-based strategies for sarcopenia management, from established interventions...
Association of Alzheimer's Disease Blood Biomarkers With Sarcopenia Incidence and Progression: A 12-Year Population-Based Study.
Sarcopenia is a complex and multifactorial condition, and recent studies have explored the role of neurological markers in its diagnosis and prediction. Although associations have been identified between reduced muscle strength, slow walking speed and elevated neurofilament levels (NfL), long-term...
Haptoglobin and Glutamine Synthetase May Biomark Cachexia Induced by Antiacute Myeloid Leukaemia Chemotherapy.
Anticancer chemotherapy is an underappreciated contributor to cancer cachexia, an often-irreversible body-wasting condition that causes 20%-30% of cancer-related deaths. An obstacle to predicting, monitoring and understanding the mechanisms underlying chemotherapy cachexia is that each cancer (and subtype) is assigned different...
Serum C-Terminal Agrin Fragment With Acute and Long-Term Exercise and Angiotensin II Type I Receptor Blockade.
Sarcopenia represents a major clinical and societal challenge facing rapidly aging populations. Accessible and specific biomarkers represent valuable tools, both in diagnosis and assessing the efficacy of therapeutic interventions. C-terminal agrin fragment (CAF) is the most commonly used blood-based biomarker...
Plasma Extracellular Vesicles Biomarkers Linked to Lower Muscle Mass, Function and Physical Performance in Sarcopenia.
As society ages, identifying individuals at risk of sarcopenia becomes essential. Several plasma biomarkers are used to assess musculoskeletal status, but their results are inconsistent. Extracellular vesicles (EVs) are investigated as disease biomarkers due to their role in transporting molecules...
