Staying informed on the latest in cachexia, sarcopenia, and wasting disorders research is essential yet challenging. The SCWD Digest offers concise updates and expert insights into significant studies and developments. We highlight and link directly to leading research, making it easier for healthcare professionals to access and apply groundbreaking findings. Our goal: empower the medical community to advance patient care worldwide efficiently.
Background: C-reactive protein (CRP) is a well-established marker of systemic inflammation, while Growth Differentiation Factor-15 (GDF-15) has emerged as a potential biomarker of cellular stress. Their relative perioperative dynamics remain incompletely defined. This prospective observational study aimed to explicitly characterize...
Sarcopenia, an age-related degenerative disease of skeletal muscle, is closely associated with osteoporosis and other bone disorders, partly due to dysregulated endocrine function of skeletal muscle. However, the specific cellular sources and molecular mechanisms driving this pathological secretory phenotype remain...
BACKGROUND
Sarcopenia is an age-related condition that contributes to disability and healthcare burden worldwide. Yet cross-national evidence on prevalence and multi-level risk factors is limited.
METHODS
We pooled data from 10 nationally representative or population-based ageing studies, including 144 226 adults aged ≥50 years...
BACKGROUND
Sarcopenia is a progressive muscle-wasting condition driven in part by chronic inflammation; however, the specific inflammatory mediators that contribute to functional decline in humans and their responses to exercise remain poorly defined.
METHODS
We analyzed public ribonucleic acid (RNA) datasets to identify...
BACKGROUND
Skeletal muscle atrophy is a frequent comorbidity of metabolic disorders and chronic diseases, and despite its high prevalence, no pharmacological therapy is available, representing a major unmet clinical need. Adiponectin and its receptors are key regulators of skeletal muscle metabolism,...
BACKGROUND
Sarcopenia is characterized by progressive loss of muscle mass, strength and physical performance, yet current diagnostic tools are limited for practical and longitudinal monitoring. Extracellular vesicles (EVs) encapsulate various biomolecules, including proteins, nucleic acids, lipids and metabolites and have emerged...
INTRODUCTION
Sarcopenia, the accelerated loss of muscle mass, strength and function with age, is associated with adverse health outcomes. DNA methylation accumulates across life and methylation clocks (which provide a measure of biological age) could potentially be used to predict individuals...
BACKGROUND
Growth differentiation factor-15 (GDF-15), a stress-induced cytokine, has been implicated in pathways related to muscle degeneration, although findings regarding its association with sarcopenia remain heterogeneous. This study investigated the association between serum levels of GDF-15 and sarcopenia progression in community-dwelling...
Cancer cachexia significantly impacts the quality of life of cancer patients, predicting therapy response and survival. Cachexia prevalence and severity increases over the course of disease progression, affecting up to 80% of patients with metastatic cancer. Despite this, cachexia is...
PURPOSE
Cancer cachexia is a life-threatening complication of advanced malignancies, driven by profound systemic metabolic reprogramming and anorexia. Insulin action is markedly impaired in patients with cancer and may contribute directly to cachexia pathogenesis. However, the interplay between weight loss, food...
Cancer cachexia is characterised by progressive skeletal muscle wasting and dysfunction, yet the early events that precede overt muscle wasting remain poorly defined. Here, we utilised a time-coursed C26 carcinoma model in male and female mice to define the pre-cachectic...
Cancer cachexia is a metabolic syndrome commonly observed in patients with pancreatic ductal adenocarcinoma (PDAC), characterized by wasting of skeletal and cardiac muscle. This condition is associated with the neurohormonal stress response and activation of the sympathetic nervous system. However...
BACKGROUND
Sarcopenia is a progressive skeletal muscle disorder prevalent in older adults, yet its role as a risk factor for acute postoperative cognitive decline-an early manifestation within the spectrum of perioperative neurocognitive disorders (PND)-remains underexplored. We hypothesize that preoperative sarcopenia increases...
