BACKGROUND Thalassemia major and its treatment by stem cell transplantation can have deleterious effects on bone integrity. This study assesses the adverse effects of transplantation on growing bones of pediatric thalassemic patients. METHODS Bone mineral density (BMD) of 20 patients from three thalassemia classes whose mean (SD) age was 7.4 (3.8) years were tested with a Norland XR-46 device...
Peak bone mass achieved in adolescence is a determinant of bone mass in later life. In order to identify genetic variants affecting bone mineral density (BMD), we performed a genome-wide association study of BMD and related traits in 1518 children from the Avon Longitudinal Study of Parents and Children (ALSPAC). We compared results with a scan of 134 adults with high or low hip BMD. We identif...
PURPOSE This study investigated the correlations among BMD, nutrient intake, basal physical fitness and serum markers in elderly women with osteopenia. METHODS Bone Mineral Density (BMD) was measured in 54 elderly women (60-77yrs) by using dual energy X-ray absorptiometry (DEXA). The subjects were divided into an osteopenia group (OG; n = 29) and a normal group (NG; n = 25). A physical fitnes...
BACKGROUND Reduced bone mineral density (BMD) is common in adults infected with human immunodeficiency virus (HIV). The role of proximal renal tubular dysfunction (PRTD) and alterations in bone metabolism in HIV-related low BMD are incompletely understood. METHODS We quantified BMD (dual-energy x-ray absorptiometry), blood and urinary markers of bone metabolism and renal function, and risk fa...
BACKGROUND The effect of diet on bone mineral density (BMD) remains controversial, mainly because of difficulties in isolating dietary factors from the confounding influences of age, lifestyle, and genetic factors. OBJECTIVE The aim of this study was to use a novel method to examine the relation between BMD and diet. DESIGN A co-twin control study design with linear regression modeling was ...
BACKGROUND Plasma total homocysteine (tHcy) has been associated with hip fracture but not directly with bone mineral density (BMD). We examined the association of hip BMD with levels of plasma tHcy, folate, and vitamin B12 and the methylenetetrahydrofolate reductase (MTHFR) 677C-->T and 1298A-->C polymorphisms. METHODS Bone mineral density was measured between 1997 and 2000 in 2268 men and 30...
Evidence suggests the existence of a close relation between lipid metabolism and bone remodeling. We hypothesized that polymorphisms of genes that play a role in lipid metabolism, such as those for forkhead box C2 (FOXC2) and perilipin (PLIN), might affect bone mineral density (BMD). We thus examined the possible relationships between a -512C --> T polymorphism of FOXC2 and a 1243C --> T polymo...
BACKGROUND AND PURPOSE Factors that lead to periprosthetic bone loss following total hip arthroplasty (THA) may not only depend on biomechanical implant-related factors, but also on various patient-related factors. We investigated the association between early changes in periprosthetic bone mineral density (BMD) and patient-related factors. PATIENTS AND METHODS 39 female patients underwent ce...
Raloxifene hydrochloride therapy effectiveness in bone mineral density (BMD) changes compared to calcium and vitamin D3 therapy over a 2-year period. Case-control study: a group of 254 women was prescribed raloxifene (raloxifene hydrochloride) together with calcium and vitamin D3 while other group of 254 women used calcium and vitamin D3 therapy. BMD was measured at the hip, spine and forearm a...
PURPOSE Osteoporosis is currently receiving particular attention as a sequela in survivors of childhood osteosarcoma. The aim of this study was to evaluate bone mineral density (BMD) changes during methotrexate-based chemotherapy in children and adolescents with osteosarcoma. METHODS Nine patients with osteosarcoma were included in this retrospective study and compared with eight healthy cont...
