Background: Surgical treatment of type 2 diabetes, specially in obese patients, has provided good results in the control of blood glucose and Hb1Ac although its effect on bone health is not clear. The aim of this study was to evaluate gene expression of bone remodelling markers in type 2 diabetic Goto-Kakizaki (GK) non-obese rats after gastrojejunal bypass and sleeve gastroplasty, and their relationship with hormonal parameters.Materials and methods: We ...

Bone therapeutics is a bone cell therapy company addressing high unmet medical needs in the field of bone fracture repair, more specifically in non-union and delayed-union fractures where the bone repair process is impaired. The company has developed a unique allogeneic osteoblastic cell product (ALLOB®) derived from bone marrow which is currently tested in humans in the indication of delayed-union fractures. The purpose of the study was to directly compare ALL...

Objectives: Cross-sectional studies show that exercise may have positive effects on bone outcomes in youth. However, there is no evidence from longitudinal studies, which type of sports can induce improvements in bone acquisition in adolescent athletes. Therefore, this study aimed to investigate the longitudinal differences in bone acquisition and bone metabolism between adolescent males participating in osteogenic (football) and non-osteogenic (swimming, cycling) sports compa...

Dietary Ca insufficiency is a common finding, independently of socio-economic status. A low Ca intake (CaI) increases bone turnover leading to bone loss. This effect becomes more important during estrogen withdrawing. We previously found that a mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) enhances Ca and P absorption (Abs), being a suitable tool to optimize its bioavailability and consequently bone health. The present study evaluated the effect of ...

Objectives: To evaluate progression of BMD and bone mineral content (BMC) during pubertal development and Influence of body composition and vitamin D on BMD and BMC in children and adolescents.Material and method: This cross sectional study was part of an ongoing health survey of Delhi school children which recruited 1905 apparently healthy school children (835 boys; 1070 girls) in the age group of 6–17 years. After brief history, anthropometry and ...

Objectives: To evaluate musculoskeletal development using pQCT and DXA in childhood onset inflammatory bowel disease (IBD).Methods: Prospective longitudinal study with 12 months follow-up in 43 children (23 males) with IBD: 30 crohn’s disease(CD), 13 ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU). pQCT at 4% and 66% radius, DXA for total body (TB), lumbar spine (LS) bone mineral content were assessed at baseline and 12 mo...

Introduction: Osteoporosis is a common complication in patients with chronic cholestasis, usually characterized by reduced bone formation. Ursodeoxycholic acid (UDCA) improves differentiation and mineralization and counteracts the damaging effects of bilirubin and lithocholic acid (LCA) in osteoblastic cells. Moreover, UDCA decreases apoptosis in a number of cell lines, but this antiapoptotic effect has not been investigated in bone cells.Aims: To assess...

Low bone formation is considered to be the main feature in osteoporosis associated with cholestatic and end-stage liver diseases. Previous studies have demonstrated the deleterious consequences of retained substances such as lithocholic acid (LCA) and bilirubin (Bil) on osteoblastic cells. These effects are neutralized by ursodeoxycholic acid (UDCA). To gain new insights into cholestatic-induced osteoporosis, we have assessed the differential gene expression of osteoblastic ce...

Objectives: Children with Duchenne muscular dystrophy (DMD) receiving long-term glucocorticoid (GC) therapy are at risk for osteoporosis and fragility fractures. Recent studies showed that cortical thickness and areas were associated with increased fracture risk. Digital X-ray measurement of the cortical thickness of the metacarpal bones has a potential role as a marker for bone health in children, but has not been evaluated in DMD. The aim of this study was to compare bone ag...

Patients with osteoporosis require treatment with therapies that reduce the risk of fracture which at the spine is significantly influenced by bone microarchitecture. Quantitative computed tomography (QCT) and dual X-ray absorptiometry (DXA) allow measurement of bone mineral density (BMD), a known indicator of fracture risk. Trabecular bone score (TBS) is a novel gray-level measurement derived from spine DXA image texture that is related to microarchitecture and associates wit...
