Patients are often referred to osteoporosis clinics with a radiological diagnosis of osteoporosis. Previous studies attempting to ascertain risk of osteoporosis from radiographs have been conflicting. The aim of our study was to determine how reliable spinal radiographs were at detecting low bone density compared with Dual Energy X ray Absorptiometry (DXA). We retrospectively measured the Bone ...

Background: osteoporosis is characterized by a reduction in bone mineral density, skeletal microstructure breakdown, increased fragility, and fracture susceptibility. Osteopenia the preceding step to because it causes decrease mass, reduces person's quality of life. Periostin (encoded Postn), its name derived from fact that was first detected periosteal osteocytes osteoblasts. deficiency has be...

BACKGROUND To assess the cost-effectiveness of drug therapy to prevent osteoporotic fractures in postmenopausal women with osteopenia in Korea. METHODS A Markov cohort simulation was conducted for lifetime with a hypothetical cohort of postmenopausal women with osteopenia and without prior fractures. They were assumed to receive calcium/vitamin D supplements only or drug therapy (i.e., raloxi...

1. The mechanisms underlying gastrectomy osteopenia are not yet clear. The gastrectomy-associated cobalamin (vitamin B12) deficiency may favour osteopenia and skeletal fractures. Also, the exclusion of the duodenum from the food passage may contribute to gastrectomy osteopenia. To investigate this, rats were gastrectomized and the passage of nutrients restored either with the duodenum excluded ...

INTRODUCTION Reduced bone mass density (BMD) is a frequent observation in HIV-infected persons. Relationship between body mass index (BMI), weight, height and BMD was reported for many populations. In particular, BMI has been found to be inversely related to the risk of osteoporosis. METHODS This is a cross-sectional, monocentric study where all HIV-infected patients referred to first DXA sca...

Introduction. Patients with rheumatoid arthritis (RA) are twice as likely to have osteoporosis (OP) compared the general population. The strength of bones depends on mineral substances, mainly represented by calcium phosphate microcrystals. chief role in regulation calcium-phosphorus metabolism is played vitamin D and parathormone (PTH). aim study. To investigate markers patients accompanied bo...

CONTEXT Sleep deprivation has detrimental metabolic consequences. Osteopenia and sarcopenia usually occur together and increase risk of fractures and disease. Results from studies linking sleep parameters to osteopenia or sarcopenia are scarce and inconsistent. OBJECTIVE To examine the associations of sleep parameters with osteopenia and sarcopenia, considering the influence of sex and menopa...

OBJECTIVE To investigate rates and predictors of change in bone mineral density (BMD) in a cohort of aging men with or at risk for HIV infection. DESIGN A prospective cohort study among 230 HIV-infected and 159 HIV-uninfected men aged at least 49 years. METHODS Longitudinal analyses of annual change in BMD at the femoral neck, total hip, and lumbar spine. RESULTS At baseline, 46% of men h...

OBJECTIVES The goal of this study was to examine the associations between severe osteopenia and osteoporosis and/or sarcopenia on frailty status, a major geriatric syndrome in community-dwelling older women. DESIGN Cross-sectional analysis. SETTING Women's Health and Aging Studies II (WHAS-II), Baltimore, Maryland. PARTICIPANTS AND MEASUREMENTS The analytic sample for this study included ...

BACKGROUND AND AIMS Children with Crohn disease are at increased risk for osteopenia and osteoporosis. Early development of osteopenia can increase the lifetime risk for fractures and may be amenable to early intervention. The gold standard for measuring bone mineral density (BMD) and fracture risk is dual x-ray absorptiometry (DXA), but this involves some radiation and specialized programs for...
