NCT00670319
To study the effect of long-term treatment with raloxifene, compared with placebo, on the rate of new vertebral fractures in osteoporotic postmenopausal women with and without existing vertebral fractures.
NCT00668447
The purpose of this study is to test the effect of 1 year of added dietary soy protein and/or soy isoflavones on bone mineral density in late postmenopausal women.
NCT00664053
The purpose of this study is to examine whether muscle strength and balance will improve in women with frailty selected for dehydroepiandrosterone sulfate (DHEAS) levels below 550 ng/dl treated with DHEAS supplementation and Hatha yoga. Investigators believe the effects of both treatments will improve outcomes more than either treatment alone and may be additive; in addition, lean body mass, skeletal muscle mass, markers of bone turnover and physical performance will improve following treatment with DHEA and/or yoga.
NCT00655577
The significance of this population-based study is in producing new information for planning interventions and rehabilitation programs for the elderly, planning education of health care personnel and planning national health education programs for different age groups. The study consists of an epidemiological cross-sectional study and a randomized controlled intervention study. The study population consisted of all the 1689 home-dwelling women born during 1924-1927 residing in Oulu, Northern Finland, who were asked to a screening visit including bone mineral density (BMD) measurement of the distal radius in 1997. 1222 women attended the clinic and were afterwards mailed a postal questionnaire focusing on lifelong risk factors for osteoporosis, e.g. the amount of physical activity at work and during leisure time, daily intake of calcium and use of alcohol and cigarettes. Those with BMD value more than 20% lower than the reference value, underwent a densitometry of the hip. All women with femoral neck BMD more than 20% below the reference value (n=160) were randomly selected to either exercise (n=84) or control (n=76) group. At baseline and after that annually during the 30-month intervention, balance, muscle strength, aerobic capacity, walking speed, cognitive functions and mood are measured from all the participants. Hip BMD will be measured annually. The exercise group participates in a supervised training program with weekly sessions from the beginning of October to the end of April. In addition to the supervised sessions the participants train daily at home. From April to October the exercises are performed purely at home. The training regimen consists of balance, strength and impact exercises. The intervention group keeps diary of their daily physical activity. The number and severity of falls are recorded from both the groups. The purpose of the study is: 1. to identify factors accounting for low BMD in elderly home-dwelling women with severe osteopenia. 2. to evaluate how supervised regular weight-bearing exercise program affects BMD in elderly home-dwelling women with severe osteopenia 3. to evaluate how supervised regular balance and muscle training affects balance and muscle strength in elderly home-dwelling women with severe osteopenia. In addition the aim is to: 4. study how regular supervised exercise affects the incidence and severity of falls, mood and cognitive functions in women with severe osteopenia. Hypothesis and research methods The main hypothesis is that long-term supervised, mainly home- based regular impact-type and balance and muscle exercises can improve balance and muscle strength of lower extremities and maintain bone mass in elderly women. We also hypothesize that the incidence of falls is lower in the exercise group than in the controls and that the falls are more injurious in the control group than in the intervention group during the follow-up period
NCT00013546
This study will evaluate the effects of hormone replacement therapy on patients with Turner syndrome (TS)-a genetic disorder in females in which part or all of one X chromosome is missing. Most girls and women with TS have underdeveloped ovaries-the female reproductive organs that produce the female sex hormones estrogen and progesterone, and smaller amounts of the male sex hormone, testosterone. These hormones affect muscle and bone strength, sex drive, energy, and an overall sense of well being. Estrogen may also play a role in memory and mood and have a protective effect against heart disease. Women with TS have a much higher risk of developing osteoporosis (loss of bone density), high blood pressure, high cholesterol and diabetes than women without this disorder. Girls and women with Turner syndrome between the ages of 14 and 50 years may be eligible for this 2-year study. Three months before beginning treatment, all patients will wear an estrogen patch and take a progesterone tablet daily for 10 days each month. They will then be randomly assigned to one of two treatment groups to compare the effects of estrogen alone with estrogen plus testosterone on bone strength, muscle and fat mass and psychosocial well being. Both groups will wear an estrogen patch and take oral progesterone. One group will also wear a testosterone patch while the other group will wear a placebo patch (a patch that does not contain any testosterone). Neither study participants nor the doctors will know who is getting the testosterone until the study is complete. Patients will undergo the following procedures before beginning treatment and at 6, 12 and 24 months after starting treatment: * Physical examination. * DEXA scans (dual energy X-ray absorptiometry) to measure body composition and bone thickness. Low radiation X-rays scan the whole body to measure fat, muscle and bone mineral content.. * Magnetic resonance imaging (MRI) scan of the abdomen to measure the amount of fat around the internal organs. The patient lies on a stretcher in a large tube surrounded by a magnetic field during the scanning. The procedure uses a strong magnet and radio waves to produce the images. * Heel ultrasound to measure bone thickness. The heel is placed in a chamber and sound waves pass through it to produce images. * Oral glucose tolerance test (OGTT) for diabetes and problems with carbohydrate metabolism. The patient drinks a sugary substance. A small amount of blood is drawn before taking the drink and four times afterwards. * Blood and urine tests to measure blood counts, liver and kidney function, ovarian hormones, growth factors, thyroid function, blood lipids, bone strength markers, and to test for pregnancy. * Blood pressure measurements. * Psychological testing for the effect of treatment on mood, self-esteem, quality of life, social shyness, anxiety and sexual function. * Neurocognitive tests (at first inpatient visit and 1 and 2 years after starting treatment) to measure nonverbal memory and visual-perceptual abilities. During the hospital admissions, patients will be given a "metabolic diet" that contains specific amounts of salt and carbohydrates to ensure accurate blood pressure and sugar metabolism measurements. Patients will keep a record of their menstrual periods and physical activity throughout the treatment period.
NCT00001916
In this study researchers would like to learn more about the low levels of bone mineral density seen in approximately half of women in their forties diagnosed as currently having or previously had depression. Bones are always undergoing a process of building (formation) and breakdown (resorption). This process is referred to as bone remodeling. When more bone is formed than resorbed, the density (level of calcium) in bone increases and the bones become stronger. However, if more bone is resorbed than formed the density of bone decreases and the bones become weak. This condition is called osteoporosis. It is unknown if women with depression have decreased bone mineral density as a result of too much breakdown of bone or not enough building. It is important to know the cause of low bone mineral density because it will influence the way a patient is treated. Medications like bisphosphonates are used when there is too much bone breakdown. Growth hormone replacement can be given in cases where there is not enough bone production. Presently, bone biopsy and a procedure known as histomorphometry can determine what processes are going on in bones. Researchers have decided to use a sample of bone (biopsy) from part of the hip bone (iliac crest). In addition, researchers will collect a sample of bone marrow (the soft tissue found in the center of bones) to tell them more about the biochemical, cellular, and molecular processes that may be contributing to the problem of decreased bone density in depressed premenopausal women.

NCT00523835
Klinefelter syndrome (KS) is the most common sex-chromosome disorder with a prevalence of one in 660 men and is a frequent cause of hypogonadism and infertility. It is caused by the presence of extra X-chromosomes, the most common karyotype being 47,XXY. The phenotype is variable, but the most constant finding is small hyalinized testes, hypergonadotrophic hypogonadism, infertility, eunuchoid body proportion, increased height and learning disabilities. Klinefelter syndrome has been associated with increased prevalence of diabetes, osteoporosis and cardiovascular diseases but the pathogenesis is unknown. Accordingly the aim of the study was to investigate measures of body composition, insulin sensitivity, bone mineral density, echocardiography, as well as biochemical markers of endocrine, metabolic and bone function in KS and an age-matched control group.
NCT00191425
The primary purpose of the study is to compare 3 different osteoporosis therapies following one year of teriparatide.In the first year,all eligible patients received open-label teriparatide 20 micrograms/day.After 1 year, patients are randomly assigned to one of 3 possible follow-up treatment regimens for the second 12 months: continuation of teriparatide, switch to raloxifene, or no pharmacological treatment(other than the calcium and vitamin D supplements that everyone receives). Patients are stratified into 3 subsets: (a) patients who have never received any anti-osteoporosis treatment before; (b) patients who received prior antiresorptive treatment successfully; (c) patients who failed to respond adequately to prior antiresorptive drugs (such as bisphosphonates or raloxifene) in the past. These latter patients are not randomized at month 12 but will continue treatment with teriparatide 20 micrograms/day throughout the second year.

The purpose of the study is to determine the effect of a short educational program on young women's knowledge and beliefs about osteoporosis. They hypothesis is that following the intervention women who receive the educational program will have greater knowledge and beliefs about osteoporosis.
NCT00465387
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.
NCT00346190
To determine whether administration of Alendronate early is more effective than late in the prevention of osteoporosis following a hip fracture
NCT00191802
The purposes of this study are to evaluate the acceptance of the subcutaneous drug teriparatide over 6 months of therapy in patients with severe osteoporosis in Canada, and to evaluate how often such patients are actually able to use the injection; to obtain additional safety data (side effect data) that will supplement the existing database of adverse events that have been reported to-date in clinical trials by patients treated with teriparatide; to document the prior use of other osteoporosis therapies in this patient population, and ongoing use of other osteoporosis therapies during the study; and to describe the baseline demographics and disease state of these severely osteoporotic patients.The purposes of the study extension are to continue to assess the acceptance of the subcutaneous drug teriparatide over up to 18 months of therapy in patients with severe osteoporosis in Canada, and to continue to assess how often such patients are actually able to use the injection; to obtain additional safety data (side effects) that will supplement the existing database of adverse events that have been reported to date in clinical trials by patients treated with teriparatide.
NCT00191321
A pilot study on the use of Teriparatide in severe osteoporotic women with hip fracture and submitted to hip replacement The primary objective of this study is to obtain preliminary data, in a pilot group of postmenopausal women with established osteoporosis and a recent hip fracture, who underwent hip replacement 3-6 months before screening phase, about the effect of teriparatide on: * bone turnover markers: CTx, PINP and BSAP when given at the dose of 20 mcg/day by subcutaneous route for 18 months. The secondary objectives of the study are as follows: * Effects of teriparatide on lumbar spine and non-prosthetic femur bone density, as assessed by BMD measurement with dual energy x-ray absorptiometry (DXA) * Effects of teriparatide on quality of life and back pain during treatment.
NCT00000413
This study will test an osteoporosis prevention program aimed at preadolescent girls between the ages of 10 and 12 who have not yet started their menstrual periods. Girls in this age group are adding large amounts of new bone to their skeletons. Adding more bone at this time of life can reduce a person's chances of developing osteoporosis (thinning bones) in later years. We will look at how this osteoporosis prevention program affects the amount of calcium in the girls' diets, the amount of weight-bearing exercise they do, and their bone mass measured using ultrasound testing of the heel.
