Background: Among body composition phenotypes there is no consensus on definition and consequences of sarcopenic obese phenotype. The recommended method to quantify the muscle mass is the dual energy X-ray absorptiometry (DXA), based on measurement of total fat mass and appendicular lean mass. A high BMI may provide a great bone mineral density (BMD) in many individuals, but it does not guarantee optimal bone strength. The aim of our study is to investigate the influence of sa...

Background: Sarcopenic obesity is usually defined by the combination of sarcopenia and obesity but there is not a standard definition yet. The recommended method for the quantification of muscle mass is dual energy X-ray absorptiometry (DXA), based on assessment of total fat mass and appendicular lean mass. Low Body Mass Index (BMI) used to be considered as a risk factor for fragility fracture. However, recent evidences have demonstrated a correlation between BMI and vertebral...

Background: An inadequate intake of nutrients, low levels of physical activity, and chronic diseases contribute to reduce muscle mass and physical performance in elderly. WHO reported that number of individuals aged ≥60 years will triple in 2050, with the sub-population aged >85 years that will grow faster than the others. Market of nutraceuticals and dietary supplements is growing in Italy, in particular aimed to improve health in elderly. Objective of this scoping ...

Background: Post-menopausal women generally present reduced serum levels of vitamin D, reduced VDR expression in skeletal muscle cells, and a gradual loss of muscle mass and muscle function. The relationship between serum 25-hydroxyvitamin D [25(OH)D3] levels and muscle strength has been extensively investigated, even though there is no agreement in literature. Therefore, aim of our study was to evaluate the effects of vitamin D on 25(OH)D3 levels, muscle strength, and physica...

Background: Bone involvement in patients with β-thalassemia is well known, but only few studies have analyzed bone microarchitecture and the prevalence of intervertebral disc calcifications (IDCs) in these patients. The aim of our study was to evaluate the bone quality in a group of patients with β-thalassemia in terms of geometry and microarchitecture properties; moreover, we evaluated the presence of IDCs in these patients.Material and method...
