Active clinical trials for "Osteoporosis"

Prebiotics have been linked to increased calcium absorption in animal and human studies (particularly in adolescents and in premenopausal women). Similarly, probiotics have been found to benefit calcium homeostasis in pregnant women, and to promote bio-mineralization in animal models. The effect of symbiotic on calcium absorption has been tested in rats, but not in human studies. The primary objective of this study is to investigate the effect of daily consumption of a functional symbiotic yogurt containing inulin and Lactobacillus rhamnosus compared to a control yogurt, on calcium absorption in young adult women. A secondary objective is to relate changes in calcium absorption following yogurt consumption, with calcium metabolism, vitamin D status, bone mass, calcium intake and overall composition of habitual diet.

This study evaluates the longitudinal, dose-dependent effects of jumping on bone health in young women. The women will be divided into 9 groups of varying jump height and repetitions, with a tenth group serving as control.

To minimize fracture risk, diverse and varied training of high intensity (multimodal training) is recommended to increase bone strength. However, the effectiveness of different training programmes performed in community settings remain uncertain. The present study aimed to evaluate the feasibility and the effectiveness of 19-week of multimodal training in a local community center in Copenhagen, Denmark. The health promotion initiative had special emphasis on musculoskeletal health in postmenopausal women.

Vitamin D deficiency is proposed to be prevalent in community-dwelling older adults, with prevalence substantially higher among older adults in residential care facilities. Musculoskeletal health is compromised in older vitamin D deficient individuals and alongside frailty, sarcopenia and osteoporosis associated with ageing, affected individuals are at increased risk of falls and fractures. Vitamin D supplementation is an effective intervention for fall prevention and, along with calcium supplementation, in fracture risk reduction in institutionalised older adults. Thus, monitoring vitamin D status and treating deficiency among older adults in residential care facilities may limit the substantial economic burden associated with falls/fractures in this population. The vitamin D status of older adults in residential care facilities in Northern Ireland (NI) is currently unknown, therefore, the aim of this pilot study is to determine the vitamin D status of this cohort of the population, and to define factors which may influence vitamin D status, including body mass index (BMI), mobility out-of-doors, medication use, dementia and diet. Vitamin D status will be determined via the measurement of 25-hydroxyvitamin D using liquid chromatography-tandem mass spectrometry (LC-MS/MS). In addition, biomarkers associated with vitamin D metabolism will be measured including calcium, albumin, creatinine, urea, bone turnover markers and parathyroid hormone. Factors that may affect vitamin D status will be assessed using a health and lifestyle questionnaire and dietary vitamin D intake will be estimated via analysis of the menus in the residential care facilities. Vitamin D supplementation practices in these facilities will also be assessed via analysis of drug prescription records, focusing on differences between residents who have/have not suffered a fracture. Physical measures such grip strength, timed up and go test and T-score measurement via Achilles ultrasound machine will be taken. This study will provide data on the prevalence of vitamin D deficiency in older adults in residential care facilities within NI and identify factors that predispose residents to increased risk of deficiency. Dissemination of these findings, along with analysis of current supplementation practices, will help practitioners to develop a strategy to identify those residents with vitamin D deficiency/insufficiency and thus requiring supplementation ultimately improving health and well-being. This study will also inform the design of a larger study to investigate vitamin D status, supplementation and musculoskeletal health in older adults in residential care facilities within Northern Ireland, providing important information that will ultimately contribute towards reducing falls and fractures within this population.

This study explores the effect of zoledronic acid on incident vertebral fractures and osteonecrotic lesions in children recently diagnosed with acute lymphoblastic leukemia.

Young postmenopausal women with osteopenia / or women with osteoporosis and a FRAX score below pharmacologic treatment indication have limited treatment options in the prevention of osteoporosis/treatment of osteopenia. Further, there is a concern about long-term side effects of bisphosphonate treatment among young postmenopausal women, and hormone replacement therapy has been controversial. In a pilot study 20 microgram Calcifediol Hy.D improved several muscle related function in this target population within 4 months of treatment, which can help to prevent falls and associated bone fractures. Thus the main aim of this study is to test whether Calcifediol Hy.D at a daily dose of 20 μg / day improves muscle function (lower extremity test battery) compared with (1) placebo and compared with (2) 3200 Vitamin D3 IU per day, at 3 and 6 month follow-up. As a secondary and exploratory objective of this study, the investigators will compare the beforementioned doses on muscle strength and the quality of the bones, beside muscle mass, body composition and systolic and diastolic blood pressure measurements.

This 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.

Both 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.

We 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.

The 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.
