Aim: To determine the safety, tolerability, pharmacokinetics and pharmacodynamics of the cathepsin K inhibitor MIV-711.Methods: A double-blind, placebo-controlled, randomized study in 27 healthy subjects of both genders. Single ascending doses 20–600 mg were investigated for adverse events, clinical chemistry, vital signs, ECG parameters, pharmacokinetics, and serum levels of CTX-I.Results: MIV-711 was well tolerated with no a...

Objective: Bone and muscle deficits are observed in patients with Crohn’s disease (CD). High-impact exercise (HIE), such as jumping based exercise, can provide hypertrophic and osteogenic stimulus, however to date there have been no studies of HIE in CD. This study aimed to assess the acceptability and feasibility of participating in HIE in adolescents and adults with CD.Methods: Two anonymous questionnaires surveyed adolescents and adults, respecti...

Objective: Childhood onset Crohn’s disease (CO-CD) is associated with musculoskeletal deficits. However, there are limited data regarding muscle-bone outcomes in adults with CO-CD. The current study aimed to comprehensively assess the muscle-fat-bone unit in young adults with CO-CD, using novel methods of MRI, in comparison with healthy controls.Methods: Trabecular microarchitecture and cortical geometry of the distal femur were assessed using 3T mi...

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...
