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...

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....

Anthropometric characteristics of postmenopausal women depending on appendicular skeletal mass

Povoroznyuk Vlayslav , Dzerovych Nataliia , Povoroznyuk Roksolana

The aim of our study was to evaluate the anthropometric characteristics in postmenopausal women depending on appendicular skeletal mass.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), among them anthropometric measures were performed in 79 postmenopausal women aged 40–82 years (mean age – 63.53±1....

The effect of levothyroxine therapy on vitamin D and bone mineral density

Cayir Atilla , Turan Mehmet Ibrahim , Ozkan Behzat

Introduction: Treatment in thyroid function disorders, which lead to clinical hypothyroidism, is replacement with levothyroxine. We aimed to investigate the effect of long-term levothyroxine therapy on vitamin D metabolism and bone mineral density in children.Materials and methods: Twenty-seven children with hypothyroidism receiving levothyroxine therapy (M/F: 13/14, mean age, 12.1±0.7 years) and 21 healthy controls (M/F: 13/8, mean age, 11.8±0...

Hyperuricemia, bone mineral density and TBS of Ukrainian men

Povoroznyuk Vladyslav , Dubetska Halyna

Aim of research: To determine the prevalence of hyperuricemia affecting the Ukrainian men in relation to the bone mineral density and TBS.Object of research: The Ukrainian men (n=132), age of the examined patients –from 50 to 80 years. Average age of examined patients was 58.2±1.3 years. According to the levels of uric acid in the blood serum, all patients were divided in four quartiles.Methods of research: Uric ...

A mixture of GOS/FOS ® added to a low calcium (ca) diet improved ca, phosphorus (p) and magnesium (mg) absorption: experimental model in normal growing rats

Bryk Gabriel , Chaves Macarena Gonzales , Marotte Clarisa , Medina Daniela , Coronel Magali Zeni , de Portela Maria Luz , Zeni Susana Noemi

A mixture of Galacto-oligosaccharides (GOS) and Fructooligosaccharides (FOS) are added to commercial infant formula to promote an intestinal microbiota similar to that prevalent in breast-fed infants to improve Ca bioavailability and general health, but their mechanisms are under debate.Our objective was to evaluate the beneficial effects of the mixture of GOS/FOS added to infant formulae, on the absorption of Ca, Mg and P of a low Ca diet. Changes in in...

Subsequent hip fracture in Inchon and Bucheon area of Korea (Cohort study)

Moon Kyoung Ho , Kim Ju Young , Lee Kee Haeng

Introduction: A significant number of patient who have experienced previous surgical treatment for an osteoporotic hip fracture, experienced a subsequent hip fracture (SHF) on the opposite side. The incidence of asynchronous bilateral hip fractures is 1.7–14.8%. All hip fracture patients treated at five university hospitals in the Inchon and Bucheon area of Korea, were reviewed. The patients were divided into two groups, a group that had experienced subsequent hip fractur...
