Sarcopenia
Sarcopenia Is Associated With Increased Risk of Abnormal Sleep Duration in the Older People: A 10-Year Cohort Study From China.
With the acceleration of the aging process, health issues of older people have gradually become one of the most important research topics. The older people experience significant reductions in muscle mass and physical performance. Cross-sectional studies have found an association...
Comment on 'A Causal Effect of Serum 25(OH)D Level on Appendicular Muscle Mass: Evidence From NHANES Data and Mendelian Randomization Analyses' by Ren etย al.
The JOHAS (Judgment of Objective Hypersteatosis and Atrophy in sarcopenia) index; an index for sarcopenia or low muscle mass?
Impact of sarcopenia and changes in skeletal muscle mass on prognosis of patients with pancreatic ductal adenocarcinoma receiving chemotherapy with first-line gemcitabine and nab-paclitaxel: a prospective study.
Sarcopenia is an important prognostic factor for cancer patients. Here, we prospectively examined the effects of sarcopenia on progression-free survival (PFS) and overall survival (OS) of patients with pancreatic ductal adenocarcinoma (PDAC) treated with first-line gemcitabine and nab-paclitaxel (GnP). This...
Thymic Microenvironment Remodeling in Cancer Cachexia as a Determinant of Checkpoint Inhibitor Efficacy and Toxicity.
The discovery of immune checkpoints links autoimmunity and cancer, with thymus atrophy reportedly causing autoimmune multiorgan inflammation. The impact of cancer cachexia on thymic involution and its clinical significance remains unclear. This study aimed to investigate this effect and its...
The Combination of Fat Distribution and BMI Redefines Obesity: Result From NHANES.
Body mass index (BMI) has well-recognized limitations, particularly in the context of the 'obesity paradox', where higher BMI does not consistently evaluate adverse outcomes. These limitations underscore the need for alternative approaches. This study aimed to redefine obesity using anthropometric...
Oral apigenin prevents obesity-related muscular atrophy, but not obesity itself, in middle-aged rats fed a high-calorie diet.
Obesity constitutes a growing global health concern, affecting individuals during the aging process. Flavonoids that increase tissue NAD+โฏlevels, such as apigenin (Api), are proposed for the treatment of obesity and age-related diseases. Thus, this study aimed to provide initial preclinical...
The role of body composition in the development of diabetes mellitus among childhood cancer survivors, and novel intervention strategies to mitigate diabetes risk.
The growing population of childhood cancer survivors (CCSs) experiences a large burden of comorbidities, including a markedly increased risk of diabetes mellitus. Among CCSs, prediabetes and diabetes are important risk factors for subsequent cardiovascular disease, which is a leading cause...
TAVI Success Is More Than Just the Valve: CT-Derived Sarcopenia as a Major Determinant of Long-Term Survival.
Sarcopenia, characterized by progressive skeletal muscle loss, is a silent yet powerful marker associated with survival, yet its impact on long-term outcomes in transcatheter aortic valve implantation (TAVI) remains underestimated. While frailty has been recognized as a main factor of...
Skeletal Muscle-Specific Deletion of E3 Ligase Asb2 Enhances Muscle Mass and Strength.
Maintaining skeletal muscle mass and strength is crucial to prevent sarcopenia during healthy ageing. Ankyrin repeat and suppressor of cytokine signalling box protein 2 (Asb2), an E3 ligase, has been implicated in regulating muscle mass; however, its roles on muscle...
Prediagnosis Insights Into Amyotrophic Lateral Sclerosis: Clinical Symptoms and Medication Use.
Amyotrophic lateral sclerosis (ALS) has a prolonged latency period, though its preclinical characteristics remain poorly understood. This study uses UK Biobank data to explore and compare ALS's pre-diagnostic features, including symptoms and medication use, aiming to provide insights into the...
EIF4A3 Promotes Muscle Atrophy and Aging by Inhibiting the FAK Pathway Through NEDD9 mRNA Destabilization.
Muscle atrophy has a poor prognosis, caused by various factors. Identifying a shared treatment target could address an unmet clinical need. The exon junction complex (EJC), a protein complex assembly that binds to RNA, facilitates post-transcriptional regulation by participating in...
Impact of Adipose Tissue and Lipids on Skeletal Muscle in Sarcopenia.
Although the decline in muscle mass, function and increased visceral obesity are attracting substantial attention in the ageing society, approved treatment modalities for sarcopenia/sarcopenic obesity (SO) remain limited. Elucidating effects and mechanisms of adipose tissue and lipids on skeletal muscle...
Late-Stage Skeletal Muscle Transcriptome in Duchenne Muscular Dystrophy Shows a BMP4-Induced Molecular Signature.
Duchenne muscular dystrophy (DMD) is a fatal X-linked recessive disease due to loss-of-function variants in the DYSTROPHIN gene. DMD-related skeletal muscle wasting is typified by an aberrant immune response involving upregulation of the TGFฮฒ family of cytokines, like TGFฮฒ1 and...
Impaired Autophagic Flux in Skeletal Muscle of Plectin-Related Epidermolysis Bullosa Simplex With Muscular Dystrophy.
Plectin, a multifunctional cytolinker and intermediate filament stabilizing protein, is essential for muscle fibre integrity and function. Mutations in the human plectin gene (PLEC) cause autosomal recessive epidermolysis bullosa simplex with muscular dystrophy (EBS-MD). The disorganization and aggregation of desmin...
