Active clinical trials for "Osteoporosis"

The purpose of this two year study is to examine the safety and effectiveness of alendronate (Fosamax) for the prevention of bone loss in men with prostate cancer who are on therapy to lower their testosterone levels. All men will receive appropriate calcium and vitamin D supplements and one to two years of alendronate therapy. Bone density tests will be done every six months.

This protocol is designed to compare the effect on bone of Zoledronic Acid 4 mg every 6 months when given upfront versus delayed start (based on a post-baseline BMD T- Score below -2.0 SD at either the lumbar spine or total hip, or any clinical fracture unrelated to trauma, or an asymptomatic fracture discovered at the month 36 scheduled visit) in stage I-IIIb postmenopausal women with hormone receptor positive breast cancer who will receive Letrozole 2.5 mg daily as an adjuvant therapy.

The purpose of this study is to determine whether educating parents about health and behavior management techniques will increase physical activity, calcium intake, fitness, and bone density in their children.

This is a 16-week intervention to determine the efficacy of an isoflavone-rich soy based meal supplement to improve bone health and prevent weight and fat gain in 18-19 year old college females. The primary hypothesis is that participants who receive soy will have favorable changes in blood markers of bone and less weight and fat gain. The soy is provided by Physicians Pharmaceuticals, Inc. (Revival Doctor-formulated soy protein).

Modification of individual life style factors and fall prevention programmes may have significant positive effects on fracture incidence. Also, a large number of studies have demonstrated that pharmacological therapy of osteoporosis is effective; however non-adherence to such therapy is a well recognized problem. Few studies, however, have examined the effect of particular patient education programmes on knowledge and adherence to therapy. We hypothesised that a group-based, multi-disciplinary, education programme increases the total quality of treatment for patients with osteoporosis, Patients' knowledge on osteoporosis and adherence with pharmacological therapy ect. A total of 300 patients, recently diagnosed with osteoporosis and started on specific treatment, were randomised to either the "school" or "control" group. In the school-group, patients attended four classes with 8-12 participants during four weeks (a total of 12 hours). Teaching was performed by nurses, physiotherapists, dieticians, and doctors and was based on dialogs and situated learning. The classes covered "facts on osteoporosis", "fractures and pain", "diet", "preventive measures", "balance and exercise", and "medical treatment". Teaching was designed to increase empowerment. The control group were offered the department's standard treatment including follow-up visits. All 300 patients received questionnaires regarding "Knowledge about Osteoporosis", "Level of Adherence", "Quality of life", "Dietary calcium intake", "Level of physical activity", "Falls events" registered every month by postcard, at inclusion and after 3, 12, and 24 month. BMD was examined by DXA-scan at inclusion and after 12 and 24 month. The last patient will answer the questionnaires first of May 2007.

This study will compare the bioequivalence of two new investigational combination formulations of Premarin and medroxyprogesterone acetate (MPA) with a currently marketed formulation of Premarin and medroxyprogesterone, Prempro™. Prempro is indicated for use after menopause in women with a uterus to reduce moderate to severe hot flashes; to treat moderate to severe dryness, itching, and burning, in and around the vagina; and to help reduce your chances of getting osteoporosis (thin weak bones). The purpose of this study is to determine if these new formulations of Premarin and MPA provide the same levels of estrogen and MPA in the blood as Prempro in healthy postmenopausal women.

The purpose of this study is to determine whether zoledronic acid given intravenously every 6 months can prevent reduction in bone mineral density in women with early stage breast cancer receiving adjuvant therapy with the aromatase inhibitor drug letrozole, after having received adjuvant tamoxifen.

To determine the acceptability and benefits of use of a dietary supplement of the phytoestrogen, genistein, versus placebo on heart disease risk factors, bone density, and psychosocial outcomes in postmenopausal women.

In this study we will investigate the effects of a high-impact exercise program involving jumping on bone mass (the amount of bone) of the hip and backbone in the growing skeleton. We will also look at the effects of gradually stopping the jumping program on bone mass in the growing skeleton. A high-impact exercise program may build more bone during childhood, while the skeleton is still growing. This may help prevent broken bones due to loss of bone mass later in life. We will recruit 200 children aged 5-10 to participate in the study. For 6 months we will train the children in either a jumping or stretching program. We will then gradually reduce the amount of exercise over 6 months. We will measure bone mass in the hip and backbone at the start of the study, after jumping, and 6 months after the jumping program is stopped. We will compare the results in the jumping and stretching groups.

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.
