Objectives: We aimed to analyze bone mineralization in postmenopausal women of Southern Apulia and to evaluate the effect of obesity-related phenotypes as BMI ≥30 kg/m2, diabetes, hypertension and cardiovascular diseases.Methods: The PROF project is a population-based study on 3.356 subjects (40–99 years) analyzed by phalangeal quantitative ultrasound (QUS) to evaluate bone mineral status. A total of 2.756 postmenopausal women were ...

Background: Osteoporosis is a leading cause of morbidity in patients affected by β-thalassaemia major (TM) and intermediate thalassaemia (TI). Appropriate supportive care and identification of long-term sequels of therapy are important in thalassaemic patients. As low bone mineral quality (BMQ) in patients can be considered a marker of possible degeneration to osteopenia and osteoporosis in adulthood, we evaluated bone features in a young population followed at ‘A. P...

Objective(s): We aimed to determine the impact of microgravity-induced osteoporosis on the future of space programs.Material and methods: We performed a metanalysis of the available literature, finding out different studies about i) muscle atrophy due to the absence of workload, which can consequently induce bone loss; ii) the effect of long term inactivity on bone mass; iii) the effect of calcium and vitamin D supplementation in women and men in order t...

Objectives: Type 2 diabetes mellitus (T2DM) is associated to an higher risk of fractures despite a normal or increased bone mineral density measured by dual-energy X-ray absorptiometry (DXA).The purpose of this 3-years longitudinal study was to assess the changes of quantitative ultrasound (QUS) parameters in a group of postmenopausal women with T2DM and in healthy controls.Materials and method: The analyses were performed on a gro...

Teriparatide is the active fragment (1–34) of the endogenous human parathyroid hormone (PTH). Studies showed that chronic administration of PTH results in decreased bone mass while intermittent exposure to PTH activates osteoblast bone deposition. Most of the structural studies published so far about the effect of Teriparatide focused their attention on the amount of newly-deposed bone without investigating the quality of the newly-formed bone tissue; moreover, most of th...

Background: Adult GH Deficiency (GHD) is associated with decreased bone mass and increased fracture risk. Recombinant human GH (rhGH) replacement therapy leads to progressive increases in bone mineral density (BMD) for up to 7 years of treatment, but little is known on longer term effects of rhGH therapy on bone mass or fracture risk.Methods: 230 GHD patients (mean age 47.1 years, 52.6% female) on rhGH replacement therapy for ≥5 years were included...

Introduction: Vascularised fibula autograft combined with a massive bone allograft (Capanna 2007) is used in skeletal reconstructions in children. If vascularisation is successful a clear remodelling of the reconstruction can be observed. This study aims to define a protocol to characterise bone’s structural evolution in skeletal reconstructions through a computer-aided analysis, and attempts a biomechanical interpretation of the observed phenomena through a multiscale mo...
