Evaluation of bone mineral density at the inhabitants of Karelia

Marusenko Irina , Pashkova Inga , Polskaya Irina , Vezikova Natalia

Age is one of the most important factors that influence bone condition. At the age of 40–45 years for women (F) and 50 years for men (M) processes of bone formation and resorption are balanced, then bone resorption predominates.We examined 103 M (20–78 years) and 360 F (20–87 years), residing in the Republic of Karelia. Densitometry was performed for all patients to assess age-related changes in bone mineral density (BMD) at the lumbar spi...

Is circulating sclerostin an endocrine modulator of bone mass?

Kulkarni Rishikesh , Schindeler Aaron , Croucher Peter , Little David , Baldock Paul

Mechanosenstitive osteocytes in bone supress the local production of sclerostin in response to mechanical loading, to increase osteoblast differentiation and bone mass. In addition, sclerostin is secreted from osteocytes into the circulation. Serum sclerostin has been shown to correlate with osteoporosis and low bone mass, however there is limited evidence by which to determine whether serum sclerostin is acting either a biomark...

Tibia microarchitecture in children with recent fractures

Moon Rebecca , Gillespie Tom , Quiney Naomi , Cooper Cyrus , Harvey Nicholas , Davies Justin

Objectives: Children who fracture have lower bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DXA) than children who do not sustain fractures, but there is little data on bone microarchitecture in relation to childhood fracture. We assessed tibia microarchitecture using high resolution peripheral quantitative computed tomography (HR-pQCT) in children with recent fracture and those without a history of fracture.Methods: Children ag...

Body composition and bone mineral density in postmenopausal women

Povoroznyuk Vladyslav , Dzerovych Nataliia , Povoroznyuk Roksolana

The aim of the study was to evaluate the peculiarities of body composition in postmenopausal women depending on bone mineral density (BMD).Materials and methods: We’ve examined 8882 women aged 20–89 years (mean age – 56.7±0.14 years; mean height – 162.5±0.07 cm; mean weight – 73.5±0.16 kg). Anthropometric measures were performed in 80 postmenopausal women aged 40–82 years (mean age – 63.53±1.08 years...

Calcium carbonate supplementation of pregnant rural Gambian mothers alters offspring IGF-1 at age 7.5 years in a sex-dependent manner

Prentice Ann , Nigdikar Shailja , Moore Sophie

Objective: We have observed sex-specific effects of pregnancy calcium carbonate supplementation in 8–12 year old Gambian children, indicating slower growth after infancy in girls born to calcium-supplemented mothers but faster in boys.1,2 IGF-1 is a key driver of growth and is responsive to calcium supplementation.3 The aim of this study was to determine whether the pregnancy supplement had resulted in sex-specific effects on mid-childhood IGF1 of th...

The effect of fluoride on the DEXA score and material properties of ex vivo emu tibiae

Omelon Sidney , Nhan Kevin , Reid-Schachter Gillian , Lacroix Nicolas , Miles-Rossouw Malaika , Variola Fabio

Bone is a tough composite material, comprised of a compliant collageneous matrix, brittle apatite mineral crystals and a suite of non-collageneous proteins (NCPs). Bone material properties depend on these components, and their interactions at the mineral-collagen interface. ‘Bone mineral density’ (BMD), a parameter used to predict fracture risk, is routinely quantified by DEXA. Previous studies used ex vivo emu tibiae as a model to test the effect of organic...

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...

Vertebral fractures in the 3-year period following steroid initiation among children with chronic illnesses

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....
