Muscle loss: The new malnutrition challenge in clinical practice.

Recent definitions of malnutrition include low muscle mass within its diagnostic criteria. In fact, malnutrition is one of the main risk factors of skeletal muscle loss contributing to the onset of sarcopenia. However, differences in the screening and diagnosis of skeletal muscle loss, especially as a result of malnutrition in clinical and community settings, still occur mainly as techniques and t...

Heparan Sulfate Proteoglycan Synthesis is Dysregulated in Human Osteoarthritic Cartilage.

Osteoarthritis (OA) is a common degenerative joint disease, characterized by cartilage loss and subchondral bone remodelling in response to abnormal mechanical load. Heparan sulfate (HS) proteoglycans bind to many proteins that regulate cartilage homeostasis, including growth factors, morphogens, proteases, and their inhibitors, and modulate their localization, retention, and biological activity. ...

Betulinic acid inhibits the migration and invasion of fibroblast-like synoviocytes from patients with rheumatoid arthritis.

The aggressive phenotype displayed by fibroblast-like synoviocytes (FLSs) contributes to cartilage and bone destruction in rheumatoid arthritis (RA). Betulinic acid has been demonstrated to have a positive therapeutic effect on tumor, inflammation and immune disorder, however, the effects of betulinic acid on RA FLSs have not been verified. Therefore, in the present study, we observed the effect o...

Association between prenatal opioid exposure, neonatal opioid withdrawal syndrome, and neurodevelopmental and behavioral outcomes at 5-8 months of age.

While use of prescription opioids and medication assisted therapy (MAT) for opioid use disorder in pregnancy, as well as the incidence of neonatal opioid withdrawal syndrome (NOWS) continue to rise, little is known about outcomes for children with NOWS beyond the newborn period.

Duchenne muscular dystrophy: Focus on arachidonic acid metabolites.

Duchenne muscular dystrophy (DMD) is an incurable disease, characterized by the muscle inflammation and progressive deterioration of muscle function. We discuss and review the role of arachidonic acid (AA) metabolites in DMD in muscle fiber degeneration and regeneration and new opportunities for developing new drugs by targeting the AA pathway, providing evidence that the AA pathway could represen...

TAKling GDF-15 and skeletal muscle atrophy in pulmonary hypertension: are we there yet?

Growth/differentiation factor 15 causes TGFβ-activated kinase 1-dependent muscle atrophy in pulmonary arterial hypertension.

Skeletal muscle dysfunction is a clinically important complication of pulmonary arterial hypertension (PAH). Growth/differentiation factor 15 (GDF-15), a prognostic marker in PAH, has been associated with muscle loss in other conditions. We aimed to define the associations of GDF-15 and muscle wasting in PAH, to assess its utility as a biomarker of muscle loss and to investigate its downstream sig...
