Aim: Human gut microbiota is an important determinant of health and disease. Discoveries from recent microbiome studies have been postulated as actionable targets to treat malnutrition, diabetes, obesity among other conditions. The role of the gut microbiome on the development of the human musculoskeletal system is yet to be established. The aim of our study was to investigate the association between bacterial operational taxonomic units (OTUs) of the gut in relation to bone m...

Objective: The purpose of this study was to investigate the association between single nucleotide polymorphisms (SNPs) in leptin (LEP), its receptor (LEPR) and β adrenergic receptor (ADRB) genes and bone mineral density (BMD) in postmenopausal Korean women.Methods: The LEP c.280G>A, LEPR c.326A>G, c.668A>G, c.1968G>C, c.2096C>T, ADRB2 c.46A>G, c.79C>G, c.718T>C, c....

The objective of this study was to analyze measurement properties of BeamMed Omnisense quantitative ultrasound (QUS) of the radial and tibial speed of sound (SoS) for assessing bone health and screening bone fragility in youth. Bone fragility was defined as low whole body less head bone mineral density (WBLH BMD) measured by DXA (first tertile, 95% CI: −1.1– (−0.9)) and as past history of fractures evaluated by questionnaire. The study was conducted with 319 n...

Aim: To investigate the effect of psychoeducation program in families with osteogenesis imperfecta (OI).Methods: Sixteen family members of OI patients were included in the program. The research was designed as a semi structural, semi experimental pre and post test. The scales used were; Introductory Information Form, Burden Interview (BI), Coping Strategies Scale (CSS), Problem Solving Inventory (PSI), and Psychosocial Adjustment to Illness Scale (PAIS)....

We report a male child presenting with antenatally diagnosed bilateral talipes equinovarus, short stature, bilateral cryptorchidism and poor weight gain; born at 39 weeks gestation (birth weight 2.56 kg) to non-consanguineous Caucasian parents. Facial dysmorphism included a prominent forehead, brachycephaly, shallow orbits, a high anterior hairline, a narrow nasal bridge and small mouth with a thin upper lip. He had white sclera and was short for height (−4.4 SDS) with a...

The impact of sex and maturation on trabecular (Tb) and cortical (Ct) microarchitecture in children and young adults has not been well established. The new second-generation high-resolution peripheral quantitative CT (HR-pQCT) scanner (XCT II, Scanco Medical) incorporates three important advances to provide greater spatial resolution, direct measures of Tb thickness and spacing and measures in the Ct midshaft. The aim of this study was to identify sex and maturation effects on...

Odanacatib (ODN), a selective and reversible cathepsin K inhibitor was shown to histomorphometrically reduce trabecular (Tb) and intracortical (Ic) bone remodeling while preserving endocortical (Ec) and stimulating periosteal (Ps) bone formation (BF) in monkeys. Here, we investigate the bone site specific mechanism of ODN on bone modeling (Mo) versus remodeling (Re)-based osteons. Rhesus monkeys (13–19 yrs, n=8–11/group) were ovariectomized and treated with ...

Type 2 diabetes mellitus impairs bone quality and increases fracture risk. We showed that diabetic ZDF rats have low bone mass due to impaired osteoblastogenesis, which can be partially reversed with an intermittent parathyroid hormone 1–84 (PTH) therapy. It remains unclear, why PTH treatment does not fully restore osteoblast (OB) function in diabetic conditions. Here, we tested if high glucose (HG) conditions lead to a partial PTH resistance in osteoblasts. Pre-osteoblas...

Introduction: Benign osteopetrosis type 2 (OPTA2) (Albers-Schönberg disease) is usually associated with a heterozygous mutation in CLCN7. Patients may be asymptomatic and present following an x-ray taken for other reasons or with a low trauma fracture. There may be a family history. Homozygous mutations in CLCN7 usually result in severe disease which presents in the neonatal period or early infancy. We present a case of benign osteopetrosis associated wi...

Objectives: The aim of this study was to assess the impact of age, sex, location of injury, physical activity, dietary intake of calcium and vitamin D on injury outcome in otherwise healthy children.Materials: This study was a cross-sectional prospective study. Children aged 6 to 15 years who presented to the Emergency Department of a single tertiary paediatric referral hospital were recruited. Children were included it they were known not to have underl...
