Active clinical trials for "Osteoporosis"

The objective of the study is to demonstrate the effects that lasofoxifene has on serum markers of bone metabolism.

Study consists of an eight day inpatient visit on the General Clinical Research Center. The investigators' specific aims are to: To define the maximum safe dose of a seven day continuous administration of parathyroid hormone [PTH(1-34)] in healthy human volunteers. To estimate the effect of a seven day continuous administration of parathyroid Hormone (PTH) in escalating doses on vitamin D metabolism, markers of bone turnover and fractional excretion of urine.

This study investigated the effectiveness of a Healthy Living Awareness Program for the Prevention of Osteoporosis based on the Information-Motivation-Behavioral Skills Model (HLAPPO-IMB) in university students. The study adopted a randomized controlled trial intervention pretest, posttest, and follow-up research design. Participants were randomized into intervention (n=43) and control groups (n=44). Data were collected using a personal information form, the Osteoporosis Knowledge Test, the Osteoporosis Health Belief Scale, the Osteoporosis Self-Effective Scale, and the International Physical Activity Questionnaire Short Form. The primary outcome measure was the participants' knowledge and health beliefs about osteoporosis. The secondary outcome measure was the participants' healthy lifestyle behavior skills (self-efficacy in weight-bearing exercises, taking calcium, and engaging in physical activity). Research questions (RQ) RQ1: Does "Healthy Living Awareness Program for the Prevention of Osteoporosis based on the Information-Motivation-Behavioral Skills Model" expand participants' knowledge of osteoporosis? RQ2: Does "Healthy Living Awareness Program for the Prevention of Osteoporosis based on the Information-Motivation-Behavioral Skills Model" enhance participants' health beliefs? RQ3: Does "Healthy Living Awareness Program for the Prevention of Osteoporosis based on the Information-Motivation-Behavioral Skills Model" improve participants' self-efficacy in doing weight-bearing exercises and taking calcium? RQ4: Does "Healthy Living Awareness Program for the Prevention of Osteoporosis based on the Information-Motivation-Behavioral Skills Model" improve participants' self-efficacy in engaging in physical activity?

Determine the safety of 2MD, a vitamin D analog, when administered orally once daily for 28 days in healthy normal postmenopausal women.

Background: Circulating osteoprogenitors and RANKL expression in immune cells have been implicated in the pathogenesis of osteoporosis and vascular calcification. The role played by statin therapy in the bone-vascular axis is unknown. Methods: Twenty naïve post-menopausal osteoporotic hypercholesterolemic women will be treated with Atorvastatin 40 mg/day for three months. Blood samples will be collected at baseline and at the end of the treatment. Gene expression analysis will be performed to assess modification in OPG/RANK/RANKL expression in isolated T-cells and monocytes. A flow cytometry analysis will be used to study changes in the levels of circulating osteoprogenitor cells.

Teriparatide is a potent osteoporosis medication that helps prevent fractures, however, the investigators know little about its effect on the hip. The investigators will evaluate hip bone samples from patients treated with teriparatide before undergoing hip replacement. The information will help us understand how teriparatide might help reduce hip fracture risk.

In this study, the investigators will develop and evaluate a novel intervention using standardized patients (SPs) -- or actors playing the roles of patients -- to enhance physicians' patient-centered counseling skills regarding two frequently overused, potentially inappropriate services in primary care: magnetic resonance imaging (MRI) for acute low back pain and bone densitometry in women at low-risk for osteoporosis. The investigators will further evaluate whether intervention effects on physician patient-centeredness generalize to counseling regarding other costly, unnecessary diagnostic tests.

Harrington's metaphorical depiction captures the essence of the problem : "Osteoporosis care of fracture patients has been characterized as the Bermuda Triangle made up of orthopaedists, primary care physicians and osteoporosis experts into which the fracture patient disappears". The most effective way to achieve this goal is through implementation of coordinator-based post fracture models of care. Exemplar models have been refered to as "Fracture Liaison Service" (United-Kingdom [1-3], Europe [4,5] and Australia [6-8]) "Osteoporosis Coordinator Program" (Canada [9,10]) or "Care Manager Programs" (USA [11,12]). The objective of this trial is to assess efficacy of a new coordinator-based post-fracture program in the Saint-Joseph Hospital in Paris to improve the management of osteoporosis after fracture thanks to an optimal recommendations practice to reduce the incidence of secondary fractures. Men and women are included aged over 45 years with fragility wrist and hip fractures. Evaluation criteria are based on the evidence-based assessment (stratify risk, identify secondary causes of osteoporosis, fracture evaluation), the medication adherence, others prescriptions adherence (osteodensitometry), the incidence of secondary fractures and number of falls. Number of patients : 200 Duration of the study: 3 years Patients' participation duration: 6 months

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.
