During early life undernutrition impairs normal weight and height gain that affects bone health. During recovering it is required an extra-amount of Ca to ensure the high demands of bone mineralization. A mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) would be a useful tool to increase mineral intestinal absorption to enhancing the amount of Ca to be retained into bone. Our objective was to evaluate, in an experimental model of protein restriction (P...

Background: Hypercalcemia in childhood is rare, can be of various origin and might go unrecognized until severe signs appear. We demonstrate hypercalcemia of different causes in two infants.Case no 1.: 5-month old girl with failure to thrive, constipation, muscle hypotonia, dehydration, where total calcaemia peaked to 4.25 mmol/l. Low calcium diet, application of glucocorticoids and furosemide resulted in a drop in calcaemia to values below 3 mmol/l and ...

The first step to getting started as a post-doc is finding an appealing post-doc position. Be proactive and begin the search and application process early. One of the most critical aspects to think about is the research area. It should be something that excites you and something where you can imagine to work in for the next couple of years. Once you have decided on a research area, you can start thinking about choosing an adviser. The adviser has great power to help build a ca...

Objectives: This cross-sectional study was done in order to assess the prevalence and determinants of vitamin D deficiency in children taking in account the following parameters: children’s age, season, geographic region and ethnicity.Methods: A cross-sectional prospective study was conducted in Israeli children aged 0–18 from Meuhedet Health Services during the year of 2016 in primary care pediatric clinics throughout all different geographic ...

The relationship between BMD T-score and FX risk has not been established in patients receiving osteoporosis therapy. In the FREEDOM Extension study, continuous DMAb therapy for up to 10 years increased BMD levels with no therapeutic plateau at lumbar spine or TH [Bone et al, ASBMR 2015]. Such improvements would only be meaningful if associated with FX reductions. We investigated the relationship between TH BMD T-score and NVFX in women who received DMAb during FREEDOM and tho...

Bone has recently emerged as a novel endocrine organ regulating glucose metabolism. Ectonucleotide pyrophosphatase/phosphodiesterase-1 (NPP1) controls bone mineralisation by generating the mineralisation inhibitor pyrophosphate. In clinical studies increased activity of NPP1 has been found in patients with insulin resistance, and it has been shown to directly inhibit the insulin receptor. We hypothesised that mice lacking NPP1 (Enpp1−/−) would exhibit im...

Bone sialoprotein regulates osteoblast activity and bone formation. In knockout (BSP−/−) mouse bone marrow (BM) stromal cell cultures, the pool of osteoprogenitor (OP) cells (CFU-F number) is not different from wild-type (+/+), nor is their early differentiation (same numbers of alkaline phosphatase positive colonies=CFU-ALP, although these are smaller), while the number of osteoblast, mineralized colonies (CFU-OB) is dramatically reduced. Because ossifi...

Aim: Scoliosis is a common skeletal problem affecting 10–30% of patients with neurofibromatosis type 1 (NF1). NF1 patients have been shown to have reduced bone mineral density (BMD) which may play a role in the pathogenesis or progression of scoliosis. Our centre is one of four international centres currently evaluating the efficacy of various spinal imaging techniques and BMD as predictors for scoliosis in NF1. In our cohort we measured the lumbar spine (LS) BMD both by ...

Objective: Although metabolic syndrome is common in gout patients, recent reports that bone mineral density may actually be reduced (and falls common) in this group have led researchers to hypothesise that osteoporotic fracture may be more common in subjects with gout than in healthy controls. We tested this hypothesis in a national Danish registry.Material and Methods: We identified subjects as new users of allopurinol, a proxy for gout, for the years 1...
