Filter by:We are interested in determining if there exist a short-term response in the serum markers and hormones that participate in the regulation of bone tissue formation and breakdown to a single, high-intensity exercise session of weight lifting (resistance exercise) or jumping (plyometrics). We are also interested in determining if the bone marker response to exercise is altered by changing the negative energy state caused by the exercise treatment, when subjects are given a moderate calorie meal.
This study will compare the ability of two types of long term (12 months) weight-bearing exercise treatments (1. high-intensity jumping and 2. weight lifting) to increase bone mass of the total body, spine and hip in physically active men with osteopenia.
This 2 arm study will compare the effect of oral Bonviva (150mg, monthly) and placebo on parameters of bone micro-architecture, assessed by CT scan, bone turnover and bone mineral density. Patients will be randomized to receive either Bonviva 150mg po or placebo monthly, and measurements will be taken at baseline, and at intervals over 2 years. The anticipated time on study treatment is 2+ years, and the target sample size is 100-500 individuals.
The primary objective was to describe the safety and tolerability of up to 10 years or 7 years denosumab administration as measured by adverse event monitoring, immunogenicity and safety laboratory parameters in participants who previously received denosumab or placebo, respectively.
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.
Both tibolone and raloxifene have been demonstrated to prevent postmenopausal bone loss. During treatment with tibolone bone mineral density (BMD) of the spine has been shown to be increased between 1.8 and 5.8 % above baseline in two years, depending on the population studied. Since treatments aimed at prevention should ideally be used long-term, compliance with the treatment is crucial. Efficacy of and compliance with the two treatments will be measured and evaluated.
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.
Decreased bone strength is a serious medical problem present in many women with Anorexia Nervosa, or disordered eating. Women with weaker bones are more likely to suffer broken bones than women with normal bone strength. We are investigating whether a hormone that is naturally produced by the human body, called growth hormone, can help strengthen the bones of women with this type of disordered eating.
This trial will test the hypothesis that among 20 children and adolescents from Children's Hospital, Boston with Crohn's disease, ulcerative colitis, systemic-onset juvenile rheumatoid arthritis, juvenile dermatomyositis, systemic lupus erythematosus, mixed connective tissue disease and vasculitis, treatment of glucocorticoid-associated osteopenia and osteoporosis with 18 months of alendronate (FOSAMAX®, Merck & Co., Inc.) will result in greater improvement in the mean change of individual AP spine bone mineral density (BMD) (gm/cm2) determined by dual energy X-ray absorptiometry (DXA) than treatment with 18 months of standard of care therapy.
Estrogen is a hormone that helps prevent calcium loss and bone breakdown. During menopause, estrogen levels decrease. Insufficient amounts of estrogen may lead to bone loss and possibly osteoporosis. Isoflavones are natural compounds found in soy plants that may help provide protection against bone loss. This study will evaluate the effect of soy isoflavones on calcium absorption and bone loss in post menopausal women.
