Active clinical trials for "Osteoporosis"

Survivors of childhood cancers face a variety of long-term problems. The investigators' recent study found that osteoporosis and osteopenia were common among these patients. The factors leading to, as well as the best treatment option for, this morbidity are unclear. Bisphosphonates are currently the standard therapy for osteoporosis in the elderly. However, the efficacy and safety of bisphosphonates for treating osteoporosis in long-term cancer survivors have not been tested. The investigators hypothesize that alendronate, an orally active bisphosphonate, is efficacious and safe in the treatment of osteoporosis in these patients.

Bisphosphonates are a type of drug used to prevent and treat bone loss. The purpose of this study is to determine if zoledronate, an investigational bisphosphonate, can improve bone mineral density (BMD) in HIV-infected adults. Study hypothesis: Zoledronate will reduce bone resorption in HIV-infected persons with osteopenia.

This study aims to conduct a cost-effectiveness analysis (CEA) among the programs for preventing osteoporotic fracture. The main comparison will be made among the effects of three programs for preventing osteoporotic fractures: 1. health education; 2. exercise intervention for enhancing bone mineral density (BMD); 3. exercise intervention for preventing falls. The "cost" will be measured bases on the monetary cost of implementation of each program. The "effectiveness" will be measured includes the number of prevented osteoporotic fractures of each program, and related outcomes are the follows: 1. the medical cost of osteoporotic fracture; 2. the change of BMD in consecutive years; 3. the quality of life (QOL) of patients with osteoporotic fracture as compared to the reference population.

This study aims to improve understanding of the relationship between spinal alignment and walking and balance in people who have degenerative spinal conditions.

Sublesional bone loss after acute spinal cord injury (SCI) is sudden, progressive, and dramatic. After depletion of bone mass and the loss of architectural integrity, it may be difficult, if even possible, to restore skeletal mass and strength. Denosumab is a relative new, highly potent anti-resorptive agent that has proven efficacy in postmenopausal osteoporosis to improve bone mass and in solid tumor patients to prevent a skeletal-related event to a greater extent than that with bisphosphonate administration. In persons with complete motor lesions, bisphosphonates have not been effective at reducing bone loss at the knee, the site of greatest relevance because of its increased risk of fracture. Anti-RANKL therapy appears to be more potent than bisphosphonates in animal models of bone loss due to immobilization, suggesting that treatment with denosumab may prove to be an efficacious therapy for persons with acute SCI to preserve bone mass and strength.

Objective: To study the acute and chronic effects of whole-body vibration (WBV) exercises on the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status, and its feasibility as an intervention in frail elderly patients. Design: Randomized controlled trial. Subjects: The frail older persons meeting the Fried Frailty Criteria. Interventions: All eligible subjects were randomly assigned to 4 groups: (1) WBV group: Subjects received a whole-body vibration exercise alone; (2) Progressive resistance training (PRT) group: Subjects received progressive resistance training; (3) WBV+ PRT group: Subjects received the whole-body vibration and progressive resistance training; (4) Control group: Subjects received no intervention/training. The periods of intervention are 12 weeks. Main measures: The lower extremities blood flow (the diameters and red blood cell velocity of the common femoral artery), timed up and go test, 30-second chair stand test, five times sit to stand test, lower extremities muscle strength, balance function, balance confidence, bone density, and general health status was assessed at the beginning of the study, at instant, 12 weeks and 24 month after the intervention. Study hypothesis: Whole-body vibration exercise is a safe and effective method that can improve the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status in the frail elderly.

This study aims to evaluate the safety and analgesic effect (efficacy) of Gastrolith powder (GASP) on skeletal pain caused by osteoporotic vertebral compression fractures (OVCF) versus placebo, primarily as assessed by the Numeric Rating Scale (NRS), and Brief Pain Inventory (BPI). It is also intended to evaluate disability change with the Oswestry Low Back Pain Disability Index (ODI) and to evaluate whether GASP consumption leads to reduction in analgesic standard of care (ASOC) versus placebo, using weekly analgesic consumption diaries.

Vertebroplasty in the symptomatic osteoporotic vertebral fracture has become increasingly popular. However, there have been some limitations in restoring the height of the collapsed vertebrae and in preventing the leaking of cement. In the severely collapsed vertebrae of more than two thirds of their original height, vertebroplasty is regarded as a contraindication. We tried postural reduction using a soft pillow under the compressed level. This study was undertaken to investigate the effectiveness of the combination of postural reduction and vertebroplasty for re-expansion and stabilization of the osteoporotic vertebral fractures. single level vertebral compression fracture were treated with postural reduction followed by vertebroplasty. We analyzed the degree of re-expansion according to the onset duration.

Numerous geometric and bone mineral density (BMD) parameters can be derived from quantitative computed tomography (QCT) images of the proximal femur analyzed using dedicated software. The primary objective is to evaluate the contribution of QCT-image analysis to the prediction of the osteoporotic hip fracture risk, as compared to the reference standard, namely, dual energy X-ray absorptiometry (DXA). Study hypothesis: For predicting osteoporotic hip fracture, findings from QCT images of the proximal femur analyzed using dedicated software are superior over DXA measurements of proximal femoral BMD.

The purpose of this study is to examine the effects of essential fatty acid (EFA) supplementation on bone metabolism and frailty in postmenopausal women. The overall hypothesis is that EFA supplementation, via its immunoregulatory and anti-inflammatory activity, will decrease bone turnover, decrease prostaglandins and cytokines associated with bone metabolism and frailty, and change physical outcome measures associated with frailty in postmenopausal women with low bone mass and frailty.
