Objective: To examine relationships among daily activity levels, body composition and bone outcomes in children aged 6.7 years who were born at term with birth weights <20th centile.
Methods: Activity data collected using accelerometers were correlated with body composition and bone outcome z-scores from dual-energy X-ray absorptiometry in 36 children.
Results: Activity levels were related to body composition outcomes; for example, lean mass index (lean mass/height(2)) was positively associated with time spent in moderate activity (r=0.40, p=0.02) and negatively with time spent in sedentary activity (r=-0.50, p=0.002). Per cent time spent in sedentary activity correlated negatively with whole body bone mineral density z-score (r=-0.44, p=0.01) and hip bone mineral content (r=-0.38, p=0.03).
Conclusions: Moderate and vigorous activity levels were associated with increased lean and bone mass in this population but not with conventional measures of adiposity such as weight and body mass index z-scores. Standard measures of adiposity may mask potential benefits of regular activity.

Article Synopsis
- This systematic review investigates how body composition, particularly skeletal muscle mass, impacts vascular health measures like arterial stiffness and structure.
- Researchers conducted a thorough literature search and included 15 observational studies with over 21,000 participants, assessing various vascular health indices.
- The findings show that higher fat-free mass correlates positively with carotid artery thickness, while body fat percentage is linked to arterial stiffness, indicating a need for further research on specific body composition factors and their health implications.

Sarcopenic obesity (SO) is a body composition phenotype derived from the simultaneous presence in the same individual of an increase in fat mass and a decrease in skeletal muscle mass and/or function. Several protocols for the diagnosis of SO have been proposed in the last two decades making prevalence and disease risk estimates of SO heterogeneous and challenging to interpret. Dementia is a complex neurological disorder that significantly impacts patients, carers and healthcare systems.

Amino acid starvation by the chemotherapy agent asparaginase is a potent activator of the integrated stress response (ISR) in liver and can upregulate autophagy in some cell types. We hypothesized that autophagy related 7 (ATG7), a protein that is essential for autophagy and an ISR target gene, was necessary during exposure to asparaginase to maintain liver health. We knocked down Atg7 systemically (Atg7) or in hepatocytes only (ls-Atg7KO) in mice before exposure to pegylated asparaginase for 5 d.

Article Synopsis
- The human microbiome consists of microorganisms like bacteria and fungi that impact health, with imbalances (dysbiosis) linked to diseases such as asthma and obesity.
- Current research is exploring how the gut microbiome specifically affects joint health and diseases like osteoarthritis through inflammatory responses triggered by dysbiosis.
- The review aims to enhance our understanding of the microbiome's role in disease and emphasizes the need for further studies on the joint microbiome's impact on conditions like periprosthetic joint infection.
