Background: Resveratrol (RSV) is a natural polyphenolic compound, found in fx grapes, which possesses anti-inflammatory properties. RSV inhibits osteoclast activity and promotes osteoblastogenesis in vitro. Furthermore, RSV protects against bone loss after ovarectomy and immobilization in animal models. RSV treatment of obese men for 4 weeks resulted in an increase in bone specific alkaline phosphatase (BAP).Hypothesis: Low-grade inflammation is...

Objectives: To evaluate progression of BMD and bone mineral content (BMC) during pubertal development and Influence of body composition and vitamin D on BMD and BMC in children and adolescents.Material and method: This cross sectional study was part of an ongoing health survey of Delhi school children which recruited 1905 apparently healthy school children (835 boys; 1070 girls) in the age group of 6–17 years. After brief history, anthropometry and ...

Background: Current studies concerning the incidence of vertebral fractures are rare. Knowledge about age and sex dependency of these fractures could help focussing therapeutic decisions. Therefore, we performed a prospective study in order to find a reliable incidence of clinical vertebral fractures in an adult population.Methods: Included were all patients with radiologic confirmed clinical vertebral fractures, which occurred in the adult population (a...

Objective: Bone and muscle deficits are observed in patients with Crohn’s disease (CD). High-impact exercise (HIE), such as jumping based exercise, can provide hypertrophic and osteogenic stimulus, however to date there have been no studies of HIE in CD. This study aimed to assess the acceptability and feasibility of participating in HIE in adolescents and adults with CD.Methods: Two anonymous questionnaires surveyed adolescents and adults, respecti...

Previous studies found a negative correlation between vertebral bone marrow fat (MF) and bone density (BMD). Proposed mechanisms for this include i) a shift in stem cell lineage allocation from osteoblasts towards adipocytes, and ii) an increase in osteoclast-promoting cytokines with greater MF. However, little is known about the relationship between MF and bone markers. To assess these relationships in older adults, we used data from the AGES-Reykjavik cohort. MF was measured...

Background: In the National Osteoporosis Guide 2014 all the patients are first recommended adequate calcium and vitamin D intake. For additional treatment US FDA approves the use of medications within seven different drug groups, but no magnesium. We have therefore studied the beneficial effect of Mg added to a Ca/vitamin D regime.Study: Fifty healthy women aged above 70 years recruited from elderly center were randomized into a Mg supplementation group ...

Objectives: To evaluate musculoskeletal development using pQCT and DXA in childhood onset inflammatory bowel disease (IBD).Methods: Prospective longitudinal study with 12 months follow-up in 43 children (23 males) with IBD: 30 crohn’s disease(CD), 13 ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU). pQCT at 4% and 66% radius, DXA for total body (TB), lumbar spine (LS) bone mineral content were assessed at baseline and 12 mo...

Temporary brittle bone disease has been a controversial explanation of multiple unexplained fractures in early childhood. Evidence for its existence is growing. We report the clinical and laboratory features of 104 patients investigated personally. These patients had in aggregate 984 fractures or fracture-like lesions.Our patients included disproportionate numbers of infants born preterm or as a result of multiple pregnancy. The fractures were mainly ide...

Differentiation of osteoclast progenitor cells into mononucleated TRAcP+ pre-osteoclasts occurs in the bone marrow. But how are these cells dispatched to the future bone resorption sites? We hypothesized that the collagen type III/I-rich reticulin network of the bone marrow might provide a structural framework for localization and migration of differentiating pre-osteoclasts towards the bone surface. Therefore, adjacent sections from decalcified paraffin-embedded iliac crest b...
