Changes in Bone Mineral Density and Fracture Risk in Patients Receiving Androgen Deprivation Therapy...
OsteoporosisThe aim of this study is to determine the long term effects of two types of hormonal treatment for advanced prostate cancer (LHRH agonists and the antiandrogen bicalutamide)on the bone mineral density of patients.
Risedronate in the Prevention of Osteoporosis in Postmenopausal Women
OsteoporosisPostmenopausalPrimary Objective: To demonstrate that risedronate 35-mg once weekly is more efficacious than placebo in increasing or maintaining bone mineral density (BMD) of the lumbar spine after 1 year of treatment in women who are non-osteoporotic and 0.5-5 years postmenopausal. Secondary objectives: To demonstrate that risedronate 35-mg once weekly is more efficacious than placebo in increasing or maintaining total proximal femur, femoral neck, and trochanter BMD after 1 year of treatment in women who are 0.5-5 years postmenopausal To assess the general safety of 35-mg risedronate administered once weekly.
Intravenous Zoledronic Acid for the Treatment of Osteoporosis and Osteonecrosis in Children With...
OsteoporosisOsteonecrosis1 moreThis study explores the effect of zoledronic acid on incident vertebral fractures and osteonecrotic lesions in children recently diagnosed with acute lymphoblastic leukemia.
Bone Healing in Healthy and Post-menopausal Osteoporotic Women
Post-menopausal OsteoporosisBoth the pathogenesis and the treatment of osteoporosis may potentially interfere at different levels on the multi-stage complex cascade of events involved in bone healing/regeneration. To our knowledge no human studies have been performed to clarify the potential effect of osteoporosis on post-extraction alveolar healing. The primary outcome of the study is to compare alveolar bone changes in width and height 3 months after tooth extraction in 10 post-menopausal osteoporotic women and 10 post menopausal non osteoporotic women by the use of cone-beam computer tomography (CBCT) images. The secondary outcomes considered are: clinical changes in the external contour of the ridge and periodontal parameters in the neighbouring teeth after a tooth extraction and 3 months later. In addition the accuracy of panoramic morphometric indexes in detecting osteoporosis will be measured.
Hesperidin and Bone Health in Postmenopausal Women
OsteoporosisPostmenopausalThe primary objective of this clinical trial is to test hesperidin with and without CALCILOCK® for bone resorption suppressing effect in postmenopausal women. The secondary objective is the comparison between 41Ca technology and classical biomarker to evaluate bone resorption.
Dose-dependent Effects of Vitamin D on Bone Health
Age-Related OsteoporosisWe propose to conduct a randomized double blind trial of three doses of vitamin D, 400, 4000, and 10,000 International Units (IU) per day, to assess the effect on bone density and architecture as assessed by high resolution peripheral quantitative tomography (HR-pQCT) measurements at the radius and distal tibia, and standard Dual X-ray absorptiometry (DXA). Other measures of bone and calcium metabolism will be assessed. The trial will last as long as three years. Approximately 300 healthy men and women, aged 50-70 years of age, will be recruited, and randomly assigned to one of the three doses of vitamin D. Other outcome variables assessed include quality of life, depression, muscle strength and balance.
Changes of GCF Levels of RANKL and Osteoprotegerin in Postmenopausal Osteoporosis
Chronic PeriodontitisThe investigators evaluated the effect of initial periodontal treatment on clinical findings and receptor activator of Nuclear Factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) in gingival crevicular fluid (GCF) of patients with osteoporosis under bisphosphonate therapy within 12 months' follow-up. Clinical recordings and GCF were obtained from postmenopausal women; with chronic periodontitis and osteoporosis (Group A, n=13), with chronic periodontitis and no osteoporosis (Group B, n=12), without chronic periodontitis and osteoporosis (Group C, n=12), systemically and periodontally healthy controls (Group D, n=10) at the baseline. Recordings were repeated at the 1st, 6th and 12th months in Group A, B and C. RANKL and OPG values were measured by enzyme-linked immunosorbent assays.
Effects of Yoga on Bone Metabolism in Premenopausal Women
Bone HealthOsteoporosisThis study examined the effects of 8 months of Yoga training on bone density and bone turnover markers in premenopausal women, ages 35-50 years. The style of Yoga used was power Yoga that involved postures with a jumping component. The investigators hypothesized that the Yoga intervention would result in beneficial improvements in bone turnover markers, by increasing the bone formation marker and decreasing the bone resorption marker.
Foot Orthoses and Elderly Women With Osteoporosis
OsteoporosisThe objective of this study was to determine if foot orthoses are effective in improving balance, pain and disability in elderly women with osteoporosis.
The Effects of Therapy With Teriparatide on Vascular Compliance and Osteoprotegerin/RANKL
OsteoporosisThe purpose of this study is to determine what effect teriparatide will have on vascular (blood vessel) compliance and osteoprotegerin (bone fluid)and RANKL levels (bone cells).
