Introduction: The FRAX model is a new method to assess fracture risk and this aspect is important in menopause. The DXA is still the golden standard but the relationship between these two instruments is complex.Aim: We correlate the 10-year absolute fracture risk of hip (10-yH) and major fractures (10-yM) based on FRAX with or without bone mineral density (BMD) with lumbar DXA in menopause women, and we use a statistical model to find out whether the vit...

Background: Previous TBS studies in type 2 diabetes have suggested a deterioration of bone microarquitecture that could be related to a higher risk of fractures. However, there are no information in liver transplantation (LT) patients with new-onset diabetes after transplantation (NODAT).Our aim was to investigate TBS in LT patients and the influence of NODAT in these patients. Also, we investigated the relationship between TBS and body composition param...

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...

Sclerostin is a major negative regulator of osteoblastic activity. Serum sclerostin has a weak positive association with BMD but contradictory results have been described concerning associations with fractures. These contradictions could be explained by the fact that serum sclerostin does not reflect its action in bone. In this study we question whether serum sclerostin is associated with its expression in bone. In addition we aimed to detect associations between sclerostin in...

Objectives: Evaluation of influence the structural and functional condition of bone tissue on caries intensity in adolescents living with deficient of fluoride in drinking water (<0.4 mg/l).Methods: It was examined 200 school children (12 and 15 years old) living in Transcarpathian region.Oral examination was done to determine caries intensity in the subjects (DMFT-index). Bone quality was determined using quantitative ultrasou...

Objective: To study any possible relations of vitamin D status and metabolic syndrome (MetS) components in children, since there is evidence for extraskeletal functions of vitamin D, and its deficiency may contribute to the pathogenesis of several major diseases. In addition to explore any possible role of birth weight (BW).Methods: Clinically healthy children aged 3–9 years (n=152) were included in the study. Forty-six were born large for ...

Introduction: Most studies to date have focus on the effect of exercise interventions on bone remodeling. Furthermore, inflammation has been associated with those critical for bone physiology and remodeling. However, investigations analyzing the relationship between objective physical activity and bone metabolism and inflammatory markers and the potential interactions with BMD and body composition in older men are limited, which is the aim of the present study.<p class="ab...

Women suffer more fragility fractures in old age and have a higher incidence of fractures at the femoral neck region compared to men who have higher incidence of trochanteric femoral fractures. The purpose of this cross-sectional study was to analyze associations between physical activity (PA) and bone mass distribution at the femoral neck (FN) and trochanter (TR) in young adults. A left hip DXA scan was used to measure bone mineral density (BMD) at the integral, superolateral...

Background: The ‘adequate’ level of 25-hydroxyvitamin D (25OHD) in children remains unclear. For bone outcomes, parathyroid hormone (PTH) is an important functional biomarker. Prior studies have shown too weak a correlation between 25OHD and PTH levels to determine adequate 25OHD level.Objective: To determine adequate 25OHD level(s) in children using a normal PTH value of 65 pg/ml while adjusting for calcium intake.Design...

The R-spondins are a family of four small, secreted agonists of the Wnt signaling pathway. Growing evidence from both in vitro studies and in vivo models supports the major role of these proteins in the skeletal development processes. In humans, common genetic variation in the RSPO3 gene has been associated with BMD in large scale GWAS study.This study aimed at further investigation of the genetic and functional contributions of the R-s...
