Objective: Previous study in Hong Kong reported boy-to-girl ratio of limb fracture was 5.5:1 in the adolescent group. Chinese children have increased risk for forearm fracture during puberty. This study aimed to investigate cortical growth in healthy Chinese adolescents during pubertal growth.Methods: 214 boys and 219 girls aged between 7 and 17 years old with no bone diseases were recruited. Maturity was assessed by self-reported Tanner staging. Images ...

Objective: Grip strength is a marker of muscle mass which can optimize bone strength during puberty. While previous studies have shown AIS girls had poor bone qualities and mechanical properties when compared with non-AIS girls, the correlation between bone qualities and handgrip strength in AIS remains undefined. This study aimed to investigate the correlation between handgrip strength and bone qualities including volumetric bone mineral density (vBMD), bone geometry, trabecu...

The aim of the study was to evaluate the role of vitamin D and exercises in correction of age-related skeletal muscle changes in postmenopausal women.Materials and methods: 38 postmenopausal women aged 53–82 years (mean age – 67.00±7.08 yrs) were examined. The women were divided into the following groups: A – control group (n=10), B – women who took an individually-targeted vitamin D therapy (n=11), C – wom...

Burosumab, a monoclonal antibody targeting fibroblast growth factor 23, is now available for clinical use in children with X-linked hypophosphatemia (XLH). We aimed to explore the effects of burosumab in children with XLH in a clinical setting, considering: a) Biochemistry b) Growth c) Lower limb deformity (LLD) d) Radiology e) Motor function<p class="abstext"...

Objectives: To establish the correlations between the body composition, somatotypes and average bone mineral density (BMD) and bone mineral content (BMC) in young (17–18 y.o.) male living in Donbass region (Ukraine).Materials and methods: Anthropometric and skinfold measurements were carried out. Estimations of the calcaneal BMD (g/cm2) and BMC, (r), estimated on ALOKA-5.0 DXA machine among 156 male were done. Total body fat perc...

Objective: We investigated the effect of creatine administered in the diet for 10 weeks on bone turnover and bone quality in male Wistar rats.Methods: Rats were divided (after approval of Ethical committee 9814/2008–30 and 30793/2010–30) into four groups, ten animals in each group. G1 SLD-A group were fed a standard laboratory diet (SLD). G2 SLD-B group were fed SLD and 12 h before rats were sacrificed diet was removed. G3...

Introduction: Children with chronic kidney disease (CKD) who suffer from growth retardation have usually normal circulating GH but low IGF1, suggesting GH resistance. We have previously shown in growth retarded CKD rats an increase in suppressor of cytokine signaling 2 (SOCS2) levels, a key negative regulator of GH signaling. SOCS2 spontaneously mutated (HG) mice show an exaggerated body growth and increased bone mass. We investigated growth and GH receptor (GHR) signaling in ...

Bone marrow is the main hematopoietic organ of adults. There, hematopoietic stem cells from which all hematopoietic lineages can be generated are preferentially homing. Importantly, bone provides niches for early B cell differentiation and survival of long-lived plasma cells that produced antibodies. Thus, that perturbing bone homeostasis might impact B cell function and antibody production is a highly relevant hypothesis for patients receiving antiresorptive drugs.<p clas...

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...
