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...

Objectives: To determine the influence of conservative management upon genetically-determined metabolic derangements in osseous tissue among patients with vitamin D-dependent rickets type 2.Methods: The conservative management of the 39 patients with rickets-like diseases involved 4 stages (tab1). 1st stage included complete examination of the patient referring determination of the calcium and phosphorus in blood and urine, calcidiol and calcitriol in bl...

Although the optimal requirement of vitamin D for skeletal health in the general community remains uncertain, vitamin D deficiency impairs bone mineralisation, increases bone turnover, accelerates bone loss and increases fracture risk. Seasonal variation in the hip fracture incidenc, reported in several studies, supports a role for vitamin D deficiency in the epidemiology of hip fracture. We hypothesised that if the association is causal, then the amplitude of the seasonal var...

Introduction: Elevated FGF-23 serum levels are induced by hyperphosphatemia and are linked to poor skeletal mineralization and adverse outcomes including vascular calcification and mortality. Recently, it was shown that FGF-23 levels are substantially elevated in acute kidney injury (AKI), and that higher levels in AKI are associated with a greater risk of adverse outcomes.Methods: In 25 vitamin D deficient (25(OH)D <20 ng/ml) critically ill adults w...

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: Some of the risk factors for osteoporosis population include: chronic immobilisation, insufficient dietary supply of calcium and vitamin D, decreased physical activity and long-term pharmacological treatment (glucocorticoids, anticonvulsant drugs). In disabled children and adolescents, the negative impact of these factors may cumulate to considerably impair the quality of life.Objectives: The aim of our study was to assess the vitamin D statu...

Over 80% of Quebec woman initiate breastfeeding, and rates of exclusive breastfeeding at 6 months doubled from 2003 (9.7%) to 2009 (19.0%). To prevent deficiency, current recommendations for these infants include 400 IU/day of vitamin D. For 20 years, Quebec has offered a program of free vitamin D supplements through its public medication insurance plan (RAMQ).Objective: Program evaluation over the last decade.Methods: This is a re...

Objectives: We have previously described biochemical evidence of resistance to PTH in Indian toddlers, which reversed on calcium supplementation. We performed a post-hoc analysis on data from an RCT of vitamin D and calcium supplementation, which was designed to assess if supplementation would reduce infection rate in undernourished school children with adequate sun exposure. Specifically we investigated the effect of oral vitamin D and calcium supplementation on biochemical p...

Objectives: Previous studies have shown that burden of infections is greater in those with low body stores of vitamin D. Vitamin D is a key mediator of innate immunity and is crucial in production of cathelicidin, a potent antimicrobial agent. Vitamin D deficiency is common among Indian children; the prevalence of infections is high. Thus, aims of our study were to examine the association between: i) serum 25-hydroxyvitamin D (25OHD) concentrations and symptoms of infections a...

Objectives: To evaluate vitamin D and bone mineral density (BMD) status in children with Duchene muscular dystrophy (DMD) in relation to fractures and ambulation status using gross motor scale function classification system (GMFCS).Methods: Clinical data of 53 DMD patients (mean age 12.1 years, range 4.9–19.6) at the first visit to the Endocrine/Bone Clinic at Nationwide Children’s Hospital were retrospectively studied. The patients were strati...
