Introduction and objectives: Male osteoporosis in the Arab World and the Middle East should be considered a major public health issue, and a problem in clinical medicine which deserves adequate attention similar to post-menopausal osteoporosis. There is a great lack of awareness among men about osteoporosis, and treatment is not as well codified as in women.The aim of this study was to evaluate referrals of male patients to Osteodensitometry Unit in a Un...

Nutrition and physical activity are two main important factors influencing bone mineral mass accumulation during childhood and adolescence. Newcomer immigrant/refugee children are at a high risk of poor nutritional status. Vitamin D deficiency, in particular, and its related diseases is a major concern due to minimal sun exposure in countries in high latitude and limited dietary sources. Using Healthy Immigrant Children (HIC) polite data (n=72), we previously...

The aims of this study were to establish the prevalence of the high bone mass (HBM) phenotype in a cohort of Spanish postmenapausal women (BARCOS); to determine whether any of the HBM cases carry LRP5 or DKK1 mutations; to test the hypothesis of an inverse correlation between the number of common variant risk alleles and HBM; and to characterize the expression of osteoblast-specific and Wnt pathway genes in primary osteoblast RNA samples from two HBM cases.</...

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...

Objectives: The aim of this study was to assess the impact of age, sex, location of injury, physical activity, dietary intake of calcium and vitamin D on injury outcome in otherwise healthy children.Materials: This study was a cross-sectional prospective study. Children aged 6 to 15 years who presented to the Emergency Department of a single tertiary paediatric referral hospital were recruited. Children were included it they were known not to have underl...

STRUCTURE was a phase 3, open-label study evaluating the effect of romosozumab or TPTD for 12 months in women with postmenopausal osteoporosis transitioning from bisphosphonate therapy (NCT01796301). This study enrolled women with postmenopausal osteoporosis who had taken an oral bisphosphonate for ≥3 years prior to screening and alendronate in the year prior to screening; had a BMD T-score ≤−2.5 at the total hip (TH), lumbar spine (LS), or femoral neck (FN);...

Biogenesis and function of microRNAs can be influenced by genetic variants in the pri-miRNA sequences leading to phenotype variability. The aim of this study was to identify osteoporosis-related SNPs by affecting the expression levels of mature microRNAs.The first approach was to perform an association analysis of putative functional SNPs located in pri-miRNA sequences of bone-related microRNAs with the lumbar spine and femoral neck (FN) bone mineral den...

Introduction: Vitamin D is essential for calcium metabolism as well as for fracture prevention. It plays a major role in bone health. A high prevalence of inadequacy has been reported in many studies. A serum 25-hydroxy vitamin D level of 30 ng/ml (75 nmol/l) has been proposed as the minimum for adequate vitamin D nutrition. The prevalence of inadequacy in different regions of the world has not been well characterized. The aim of this study was to evaluate and propose new base...

Aim: Low serum vitamin D levels are common in sunny Lebanon. Vitamin D is essential component of osteoporosis management strategies. This study surveys the referral rate of Lebanese males for vitamin D testing.Subjects and methods: A 13 000 Lebanese subjects included in this study were coming for routine check-ups. Patients on renal dialysis and cancer patients on chemotherapy were excluded. Serum 25-hydroxy vitamin D is considered the best indicator of ...
