Mesenchymal stromal cells (MSC) have a potential to differentiate to osteoblasts and adipocytes. Differentiation can be stimulated or inhibited by different growth factors, including fibroblast growth factors (FGFs). In this study we evaluated the effect of FGF2 on the osteoblastic and adipocytic differentiation of MSCs in vitro.Mouse MSC-derived cells were cultured in differentiation medium that led to differentiation to osteoblasts in 14 days ...

Disorders of glucose metabolism are associated with adverse skeletal effects. Hyperglycemia impairs the function of osteoblast-like cells but the mechanisms underlying glucose toxicity are poorly understood. In this study we determined the effect of elevated extracellular glucose levels on the proliferation and osteogenic differentiation of mesenchymal stromal cells (MSC).Bone marrow cells were isolated from rat long bones, plastic-adherent MSCs were enr...

Objective: To compare whether interval BMD changes in adolescent females that can be detected using conventional dual energy X-ray absorptiometry (DXA) can also be detected using quantitative peripheral quantitative computerized tomography scans (pQCT) and quantitative ultrasound (QUS)of the os calcis.Methods: Two groups of adolescent females were recruited for assessment of BMD changes over an interval of 22–24 months. These included full time coll...

Background: Prolonged hypothalamic amenorrhoea with anovulation has been associated with hypo-oestrogenism in adolescents and has been shown to be associated with lower bone mineral density (BMD) values.Objective: To determine whether differences in BMD between oligo/amenorrhoeic adolescents at risk of low BMD and normal eumenorrhoeic controls can be detectable by quantitative ultrasound (QUS) of the os calcis.Methods: Adolescents ...

Objective: To assess the prevalence of co-morbidities in fracture neck of femur patients.Methodology: Study design: Retrospective cohort study.Setting: District General Hospital in United Kingdom.Study subject: a total of 75 patients with fracture neck of femur from 2012 to 2013 were ascertained for any associated co-morbid conditions by case note study.Results: Out of 75 patients, 61 (...

Objective: To assess the prevalence of post-operative medical and surgical complications among fracture neck of femur patients.Method: Study design: retrospective cohort study.Setting: District General Hospital in UK.Study subject: a total of 75 patients with fracture neck of femur from 2012 to 2013 were ascertained for any post-operative complications by case note study.Results: Out of...

Objectives: To assess the pharmacological management of osteoporosis in a cohort of hospitalized medical in-patients within a Welsh district general hospital.Materials and methods: We collected data using medical records on a structured proforma as a point prevalence study targeting medical inpatients aged fifty and above in an admitted hospital cohort.Results: Out of the 117 patients, 88 (75.21%) of them had greater than three ris...

Turner syndrome (TS) is known to be associated with increased risk of osteoporosis and fracture. Childhood treatment with GH has been considered standard of care for treatment of growth failure in TS, while the influence of GH on bone health has been poorly understood. The purpose of this study is to assess the influence of GH on bone microarchitecture on a cohort of TS subjects.TS subjects aged 16–45 were included. Bone mineral density (BMD) was as...

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 ...

Introduction: Effective screening for vitamin D (Vit-D) insufficiency is desirable. Pigmentation of unexposed (constitutive) skin and exposed (facultative) skin can be measured with skin colourimetry to assess dermal capability in synthesizing Vit-D and degree of sunlight exposure respectively. This study aimed at evaluating whether skin colourimetry could be used to screen Vit-D insufficiency among adolescents.Methods: 240 healthy adolescents (mean age=...
