Validity of the Actigraph-GT9X accelerometer for measuring steps and energy expenditures in heart failure patients.

Introduction: The ActiGraph (AG) accelerometer is widely used to assess physical activity (PA) in heart failure (HF) patients. However, the validity of the AG in this population remains unexplored.

Objective: Therefore, this study examined the criterion validity of the AG-GT9X for measuring step counts (SC) and energy expenditure (EE) among HF patients.

Association of creatinine-to-cystatin C ratio with computed tomography measures of skeletal muscle quantity and quality: The multi-ethnic study of atherosclerosis.

Background & Aims: Skeletal muscle (SM) health has significant prognostic value in geriatric and chronic disease populations, yet its assessment is frequently omitted due to challenges in evaluation. The creatinine-to-cystatin C ratio (CCR) is a simple serum-based measure that associates well with measured SM quantity (myopenia) and strength, but evidence for its association with SM quality (myosteatosis) is limited and conflicting. This study investigated the association between CCR and computed tomography (CT) measures of myopenia and myosteatosis.

Sex and Gender Differences in Weight-Related Biopsychosocial Factors Among Adults Receiving Buprenorphine for Opioid Use Disorder.

Introduction: Medication for opioid use disorder (MOUD) is the most efficacious treatment for opioid use disorder (OUD). MOUD uptake and continuation may be impacted by health concerns, including weight gain, and social factors, such as food insecurity, that vary between men and women. This study aimed to describe sex and gender differences in body mass index (BMI) and weight-related demographic, psychosocial, and clinical characteristics among adults receiving buprenorphine for OUD.

Highly neurogenic glia from human and mouse myenteric ganglia generate functional neurons following culture and transplantation into the gut.

Enteric neural stem cell (ENSC) therapy offers great promise for neurointestinal diseases; however, current isolation methods yield insufficient neurons for regenerative applications. Multiomic profiling of enteric glial cells (EGCs) suggests that subpopulations within myenteric ganglia (MyGa) are a reservoir of highly neurogenic ENSCs. Here, we describe protocols to enrich for intraganglionic EGCs by isolating intact fragments of MyGa, generating cultures with higher neuronal purity than traditional methodologies isolating intramuscular single cells (IM-SCs).
