Aim: Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) is an invasive treatment able to control local disease and pain of bone tumors. Unfortunately, there is not any scientific evidence of the biological effect of MRgFUS treatment on tumor cells, especially in lower dose region, where tissues are only warmed to sub-lethal temperatures. Here we investigate the effect of in vitro MRgFUS treatment, at different levels of acoustic energy (200–630 J), on ...

Patients with improved health understanding have greater autonomy over, and motivation towards, health-related lifestyles. We compared self-perceived fracture risk and 3-year incident fracture rates in postmenopausal women for a range of co-morbid diseases using data from the Global Longitudinal study of Osteoporosis in Women (GLOW).GLOW is an international cohort study involving 723 physician practices across 10 countries in Europe, North America, Austr...

Introduction: The creatine kinase (CK) is a dimeric enzyme, involved in energetical metabolism. It is present in many tissues, but higher concentration in skeletal and cardiac muscle.Therefore, conditions that involve muscle tissue may increase this serum enzyme. Such enzyme elevation is usually observed in inflammatory myopathies and others autoimmune diseases.Sometimes some elevation in CK is not fully understood out off these co...

Heritability of bone mineral density (BMD) varies at skeletal sites, possibly reflecting different relative contributions of environmental and genetic influences. To quantify shared genetic influences across different sites, we estimated the genetic correlation of BMD at the upper limb (UL), lower limb (LL) and skull (S) obtained from whole body DXA scans, using bivariate genome-wide complex trait analysis (GCTA). The study (n=9395) combined data from the Avon Longitu...

Objectives: To describe the incidence of vertebral fractures in steroid-treated children.Methods: Fractures were assessed prospectively each year for 3 years according to the Genant semi-quantitative method. Proportions of children with incident fractures were determined annually over the study period. To examine associations with baseline clinical factors, the 3-year total number of incident fractures was analyzed using multivariable Poisson regression....

Background: Elevated plasma homocysteine levels are a risk factor for osteoporotic fractures. Supplementation with vitamin B12/folic acid lowers homocysteine levels. This study aimed to determine whether vitamin B12/folic acid supplementation reduces osteoporotic fracture incidence in hyperhomocysteinemic elderly.Methods: B-PROOF is a double-blind, randomized, placebo-controlled trial including 2 919 participants aged ≧65 years with elevated homocyste...

Objectives: Osteoporosis is a frequent cause of morbidity in boys with glucocorticoid (GC)-treated Duchenne Muscular Dystrophy (DMD). We sought to determine the frequency and characteristics of the two most debilitating types of fractures, vertebral and long bone (VF and LBF), in pediatric DMD.Methods: This was a prospective, bi-centre, single-visit observational study in boys 4 to 17 years of age with genetically-confirmed DMD. The bone health assessmen...

Objective: Evaluate the clinical characteristics of all Latin American pediatric patients with Gaucher disease type 1 (GD1) enrolled in the ICGG Gaucher Registry at baseline and investigate long-term outcomes and clinical benefit of prolonged imiglucerase/alglucerase therapy in patients with manifestations of GD1 at baseline.Methods: All Latin American patients with GD1 in the ICGG Gaucher Registry (NCT00358943) who were <18 years of age at the start...

Objective: Low dietary calcium intakes and increasing adiposity in Indian adolescents may increase their risk of hypertension (Sanwalka et al., Asia Pac J Clin Nutr. 2010, Khadilkar et al., Int J Pediatr Obes. 2010). Therefore, the aim of the present study was to explore association of dietary calcium intakes and body composition with blood pressure in 10–14 year old Indian adolescents.Method: 370 apparently healt...

Low fracture (FX) incidence has been demonstrated in women with postmenopausal osteoporosis (PMO) treated with DMAb for up to 10 years in the FREEDOM extension [Bone ASBMR 2015]. Bone biopsy-based assessment of DMAb’s effects at the tissue level has demonstrated a low remodelling rate consistent with DMAb’s mechanism of action (Reid JBMR 2010; Brown JBMR 2014). From FREEDOM, we report the effects of DMAb on bone matrix mineralization in women who un...
