Active clinical trials for "Osteoporosis"

The aim of this study is to investigate potential metabolic effects of resveratrol in men with metabolic syndrome(otherwise healthy). The investigators hypothesize that resveratrol has an anti-inflammatory effect, and will increase insulin sensitivity, change the fat- and sugar-metabolism, and down-regulate bone-turnover.

The research question is, does a multifaceted, multidisciplinary intervention including small groups, chart audits and point of care tools, increase the number of people receiving optimal vitamin D therapy in the long term care (LTC) setting? Secondary outcomes include the number of falls and fractures experienced by the residents in each LTC home and the number of residents receiving appropriate bisphosphonate therapy.

This study hypothesize that radius subjecting to mechanical loading may affect excitability of alpha motor neuron innervating muscle, based on its bone mineral density or bone mineral content. A total of 80 voluntaries are planned to include in this study. Vibration will be applied the right forearm. Muscle electrical activity will be measured on ipsilateral and contralateral flexor carpi radialis (FCR) muscle at rest as EMGrms by surface electromyography (EMG). The rest-EMGrms will be measured at before and during vibration. An increase in muscle electrical activity at rest indicates an increase in motor neuron pool activation. The right distal radius bone mineral content (BMC) and density will be measured by dual energy X-ray absorptiometry (DXA). The right radius bone mineral density (BMD) and BMC will be evaluated by bone densitometer (GE-LUNAR DPX PRO). Motor unit potentials will be measured by electromyography at left flexor carpi radialis. Neurotrac ETS device will be used.

To characterize the effects of discontinuation of denosumab therapy on variables of bone histology in postmenopausal women with low bone mass or osteoporosis. Patients who have received denosumab and completed study 20050179 (NCT00293813), completed study 20050141 (NCT00330460), completed study 20060237 (NCT00515463), completed study 20030216 (NCT00089791) but did not enroll in study 20060289 (NCT00523341) will be included in this study. Patients who will participate in the off-treatment imaging study for 20080747 (NCT00890981) are also eligible.

The purpose of this study is to conduct a 12-month randomized controlled trial comparing the effects of strength and impact exercise training to flexibility/relaxation training on body composition (bone, muscle and fat mass), physical function (strength, gait, power, balance and self-report physical function and symptoms) in men currently treated with hormone therapy for prostate cancer.

SPECIFIC AIMS: We propose a three-year study to develop a high-intensity intervention to improve osteoporosis care and test a novel intervention in a group-randomized trial of 27 home health offices and 1,000 patients referred to home health care with a history of fracture. Aim 1. Develop an intervention to promote osteoporosis treatment that includes: (1) training to enhance nurse-patient and nurse-physician risk communication regarding osteoporosis and fracture risk; (2) automated prompts within the home health agency's electronic medical record system to promote appropriate osteoporosis management; and (3) implementation of osteoporosis-related standardized care pathways and order sets. Aim 2. Conduct a group-randomized trial to test the effectiveness of the intervention to promote initial use of osteoporosis medications and adherence to treatment after discharge from home health. We hypothesize that: H1: Patients in the intervention group will have increased initial receipt of osteoporosis prescription medications and calcium/vitamin D supplements to prevent and treat osteoporosis compared to patients receiving usual care; H2: Patients in the intervention group will demonstrate increased persistence in the use of these therapies compared to those receiving usual care. Secondary Aims (SA) will include exploratory analyses of fracture related morbidity and mortality, patient-reported quality of life, and health services utilization and costs.

The purpose of this study is to investigate the efficacy of systematic education (osteoporosis school) on fall frequency, compliance and quality of life of a group of patients more than fifty years of age. Hypothetically, systematic information can increase compliance to the medical treatment, decrease the frequency of falls and increase the quality of life.

RATIONALE: Zoledronate may reduce bone loss in patients receiving letrozole for breast cancer. PURPOSE: This clinical trial is studying how well zoledronate works in treating osteopenia or osteoporosis in postmenopausal women receiving letrozole for stage I, stage II, or stage IIIA primary breast cancer.

This is a dose escalation study to determine the maximum tolerable dose of Parathyroid Hormone-related Protein, PTHrP, that can be given safely over one week. The investigators plan to infuse low doses of intravenous PTHrP to determine if it leads to a sustained and progressive suppression of bone formation as occurs in humoral hypercalcemia of malignancy (HHM) or an increase in bone formation as occurs in hyperparathyroidism (HPT). Additionally, the investigators will assess the direct influence of PTHrp on markers of bone turnover, and plasma 1,25 (OH)2 vitamin D regulation in healthy human volunteers.

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Zoledronate may prevent bone loss in patients who are receiving letrozole. It is not yet known which schedule of zoledronate is more effective in preventing bone loss in patients with breast cancer. PURPOSE: This randomized phase III trial is studying two different schedules of zoledronate to compare how well they work in preventing bone loss in postmenopausal women who are receiving letrozole for stage I, stage II, or stage IIIA breast cancer.
