Active clinical trials for "Osteoporosis"

To confirm the superiority of 5 mg daily risedronate as compared to placebo in maintaining or increasing bone mass in lumbar spine in osteopenic postmenopausal women To confirm the efficacy of 5 mg daily risedronate in osteopenic postmenopausal women in maintaining or increasing bone mass in proximal femur and decreasing bone resorption To confirm general safety of 5 mg daily risedronate as compared to placebo

There is increasing evidence that the acid-base balance of diet plays an important role in the health of bones and muscles. An excess of acid in the body can result in calcium loss and muscle breakdown. Potassium bicarbonate, a base supplement, can neutralize acid within the body. The purpose of this study is to determine the effectiveness of potassium and bicarbonate, alone and combined, at reducing bone loss and preventing muscle wasting in older adults.

The ultimate objective of the proposed research is to improve the health-related quality of life of individuals with rheumatoid arthritis by reducing their risk of developing osteoporosis secondary to glucocorticoid therapy. The study has four specific aims. Specific Aim 1: To obtain descriptive information concerning patients' knowledge, beliefs and behaviors with respect to osteoporosis and osteoporosis prevention. Specific Aim 2: To identify factors that discriminate among patients in different stages of change with respect to each behavior of interest. Specific Aim 3: To compare the effects of tailored versus generic educational materials on patient adherence to the ACR Guidelines for the Prevention of Glucocorticoid-Induced Osteoporosis. Specific Aim 4: To determine if the effects of tailored educational materials are enhanced by concurrent feedback of information concerning patients' behavioral risk factor status to their physicians.

This project wills to determine the incidence of osteoporosis in our population of HIV-infected patients and to assess the efficacy and security of ibandronate, whose efficacy in post-menopausal women has already been proved.

We hypothesize that anthocyans with calcium and vitamin D have a positive effect on bone reshaping in menopausal women.

The purpose of this study is to test whether strength/weight training exercises enhance the effectiveness of calcium, vitamin D, and risedronate for the prevention and treatment of osteoporosis in postmenopausal breast cancer survivors.

Falls and osteoporosis-related fractures cause substantial morbidity and mortality in the elderly, and are an increasingly important public health concern. A comprehensive multidisciplinary and integrated community-based approach is needed to identify and manage the population at highest risk of these complications. Unfortunately, current gaps in continuity of care and health intervention result in a sub-optimal state of health service for these individuals. The Falls, Fracture and Osteoporosis Risk Control and Evaluation (FORCE) Study is a two-year randomized controlled trial evaluated on the effect of coordinated community-based, multidisciplinary approach for fall and fracture prevention in Sault Ste. Marie.

This study will examine whether whole-body vibration slows down bone loss in healthy postmenopausal women with osteopenia. Whole-body vibration is a promising novel therapy that involves standing on a platform which produces extremely small and fast up-and-down movements. Some but not all research studies have found that whole-body vibration slowed down bone loss in postmenopausal women. One of the reasons why different studies found different results may be because they used various speeds of vibration. This study looks at how different speeds of whole-body vibration influence bone mineral density differently in postmenopausal women who have osteopenia. Two hundred postmenopausal women will take part in this 12-month study. Women will be randomly assigned into three groups (67 women per group) and these groups will be compared. Group 1 will receive very fast whole-body vibration, Group 2 will receive fast whole-body vibration, and Group 3 will not receive whole-body vibration. We will look at various bone mineral density and bone quality measurements, obtained with three different types of technologies, at the beginning of the study and at 12 months of follow-up. The hypothesis of this study is that the in comparison to Group 3 (no vibration), Groups 1 and 2 will experience reduced bone loss over 12 months, and that the greatest reduction in bone loss will be experienced by Group 1. The results of this study will help us determine whether whole-body vibration at different speeds produces variable effects on bone, hence explaining the inconsistency of the results obtained in previous studies.

Bone Mineral Density (BMD) as measured by X-ray shows the amount of calcium in the bone. Low BMD may reflect osteoporosis, a condition where there is an increased risk of fracture. Women who have gone through menopause have a higher risk of getting osteoporosis because they lose calcium from their bones much faster than younger women. Women with breast cancer may have an additional risk for getting osteoporosis because of the effects of their treatment with chemotherapy. The purpose of this study is to see what levels of BMD post-menopausal women with breast cancer have, and to see if the level of BMD changes during a women's treatment after her surgery. This trial studies changes in BMD and markers of bone activity in women receiving treatment for early stage breast cancer.

Osteoporosis is a major health problem in postmenopausal women. Our long-term goal is to develop a new alternative treatment that include a dietary supplement (green tea extract) and a mind-body exercise (Tai Chi) for lessening bone loss in postmenopausal women with low bone mass. A combination of dietary supplement and moderate intensity exercise now becomes a new alternative treatment in reducing bone loss in postmenopausal women with low bone mass, due to the possible stronger effects of the combination than individual treatments. Objective: To test a CAM intervention including green tea polyphenol (GTP) and Tai Chi (TC) exercise for feasibility, and to quantitatively assess their individual and conjugate effects on postmenopausal women with osteopenia. Hypotheses: (1) 24 weeks of GTP supplement, TC exercise, and their combination will benefit bone remodeling as measured by bone biomarkers and muscle strength/physical function in postmenopausal women with osteopenia compared to those receiving placebo only, and (2) the changes in bone biomarkers associated with bone remodeling will be correlated with the changes in oxidative stress.
