NCT01049191
Osteoporosis is a common disorder of compromised bone strength causing 40-50% of women and \~25% of men to sustain fragility fractures during their lifetime. The reduction of bone strength in osteoporotic people results from loss of bone density and deterioration of bone quality. Bone quality is a complex amalgamation including macro- and micro-architecture, mineralization, turnover and damage accumulation. Currently, medications to reduce fracture risk are prescribed primarily on the basis of bone mineral density (BMD) measurement. Unfortunately, currently available BMD measurement technologies do not detect the aforementioned properties of bone quality; as such, less than half of individuals who sustain osteoporotic fractures are classified as "osteoporotic" by currently available diagnostic tools. Clearly, measures to enhance identification of those at high fracture risk are needed. High-resolution magnetic resonance imaging (HR-MRI) technology, such as that provided by MicroMRI, Inc., has outstanding potential to be such a tool. Therefore, our long-term goal is to evaluate and optimize the use of HR-MRI in fracture risk prediction; this pilot work is an essential step in attaining this goal. This research will investigate 72 postmenopausal women with normal or osteopenic BMD by dual-energy x-ray absorptiometry (DXA), 36 with prior low-trauma fractures will be compared with 36 age-, race- and BMD matched women without fracture. We hypothesize that 1.) Women with fractures will have evidence of microarchitectural deterioration on HR-MRI and 2.) Newly developed, more rapid MRI sequences designed at the UW will provide similar trabecular microstructure information more rapidly than the currently used, albeit investigational, technology produced by MicroMRI, Inc. Our specific aims are to a) Evaluate differences in MicroMRI parameters of trabecular microstructure (bone volume fraction, trabecular thickness, surface/curve ratio and erosion index) between age-, race- and BMD-matched postmenopausal women with and without fracture; b.) Correlate T2\* relaxation time (a rapid indirect MRI measure of trabecular density and microstructure) with BMD measured by DXA, and microstructural parameters measured by MicroMRI. As an exploratory aim we will investigate HR-MRI parameters of trabecular microstructure obtained using a newly developed, rapid MRI sequence referred to as IDEAL-FSE with parameters obtained using the currently available MicroMRI, Inc. sequence.
NCT02549521
Calcium and vitamin D substitution has for a long time been used to improve osteoporosis.The main storage place for magnesium is in the bone. Magnesium is direct under calcium in the periodic system making it possible to interact with the crystal structure. Some small studies have shown beneficial effects of magnesium substitution on osteoporosis. Evidence has shown improvement with calcium, alcohol, fruit and vegetable nutrients on bone loss. It has been uncertain however, which of these factors can contribute to such a change. The effect of magnesium substitution 240 mg daily as therefore studied in two parallel groups where both received calcium carbonate 1000 mg/day and cholecalciferol 10 ug/day, one got placebo and the other received magnesium. This was studied on various expressions for bone metabolism after zero, seven and 28 days in elderly females aged 70 years old.
NCT00975013
The objective of this study is to assess changes bone mineral density and bone metabolism after laparoscopic Roux-en-Y gastric bypass surgery. The investigators hypothesize that weight loss after laparoscopic Roux-en-Y gastric bypass surgery will be associated with increased bone turnover, changes in bone metabolism, and loss of bone mass.
NCT01552122
This study will evaluate the therapeutic effects and safety of odanacatib on bone mineral density in osteoporotic postmenopausal women who were previously treated with alendronate.
NCT00863590
This study assessed the safety, tolerability, and pharmacokinetics of single-dose odanacatib (MK0822) with and without food.
NCT02518763
The vitamin D deficiency (25OHD) is very common and affects about 80% of the population of French osteoporotic women over 50 years \[5\]. It contributes significantly to bone fragility and consequently the risk of fracture. To remedy this deficit, it is necessary to provide a suitable and sustainable supplementation. Changes in vitamin D deficiency ranging from undetectable to a 25OHD value very close to 30ng / ml lead to differences in therapeutic regimens, specific to each clinician in the absence of precise data in the literature. No consensus on supplementation dosages and methods have been proposed so far. Also, given the frequency of vitamin D deficiency including osteoporosis observed in the population, it became necessary to establish a single, uniform regimen for all patients with osteoporosis
NCT00558012
This trial will examine the safety, efficacy and feasibility of a single dose of intravenous zoledronic acid in the maintenance of skeletal integrity for frail, institutionalized women, who are most at risk for the deleterious outcomes of osteoporosis. The investigators will test the hypothesis that in institutionalized elderly women a single dose of intravenous zoledronic acid therapy will: (1) be efficacious as demonstrated by stability or improvement in bone mass measurements and reductions in bone turnover; (2) be safe and feasible; and (3) provide estimates for vertebral and nonvertebral fracture reduction in this cohort for use in planning a future study.
NCT00000412
During the first year after a heart transplant, people often rapidly lose bone from their spine and hips. About 35 percent of people who receive heart transplants will suffer broken bones during the first year after transplantation. This study will compare the safety and effectiveness of the drug alendronate (Fosamax) and the active form of vitamin D (calcitriol) in preventing bone loss at the spine and hip after a heart transplant. In this study, people who have had a successful heart transplant will receive either active alendronate and a "dummy pill" instead of calcitriol, or active calcitriol and a dummy pill instead of alendronate for the first year after their transplant, starting within 1 month after transplant surgery. We will measure bone density in the hip and spine at the start of the study and after 6 and 12 months, and will also check for broken bones in the spine. This research should lead to ways of preventing this crippling form of osteoporosis.
NCT00718432
Frailty, osteoporosis, and depression are three highly prevalent geriatric syndromes. Having these conditions are associated with adverse outcome in physical health, mental health, quality of life, and daily functioning. They are associated with higher mortality rates as well as increased health care cost. Risk factors, pathogenesis, clinical phenotypes, and interventions of these three geriatric syndromes are often related. Frailty is often defined as accumulations of multi-system deficiencies with increased vulnerability to multiple worse outcomes. Multifactorial, interdisciplinary integrated care models targeting frail older adults may have positive impacts on measurements associated with not only frailty, but also depression, or osteoporosis. The objective of this proposed study is to conduct a randomized control trial (RCT) to exam the effectiveness of integrated interventions on multiple outcomes among community-dwelling Taiwanese elders with high risks for frailty and/or osteoporosis, depression. We also plan to determine the differential effects of intervention between urban and rural area.
NCT00609830
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.
NCT01150071
Background: In a national Norwegian cohort of children born before 28 weeks gestation or with a birth weight less than 1000 g born in 1999 and 2000, 372 survived. Compared with earlier studies survival increased for the most immature infants, but at the cost of more early complications and a high rate of impairments, while the less immature children had fewer early complications and less impairments detectable within 5 years. These changes show the importance of monitoring outcome as treatment modalities change. Large brain haemorrhages were highly predictive of severe disabilities, but we have not found good predictive factors for milder impairments such as cognitive, behavioural and motor difficulties. However, at 5 years later function may be difficult to predict, and the children's potentials are better understood after completing several years in school. Objectives: The children will be re-examined at age 11 in order to assess their physical and mental health, and cognitive, motor and social function, and to determine if early life events and development at 2 and 5 years are predictive of long term health and functioning. MRI-studies, including functional MRI will be performed to examine if different outcomes related to brain function can be explained by differences in brain development. Methods: For all, data will be collected from the compulsory national test in 5th grade and questionnaires to the child, parents and teacher. For children in Western Norway (n=87) extensive examinations of lung and brain function, including clinical diagnostic tests and MRI, will be added. For all aspects of the study the investigators have appropriate current and historic reference populations for comparison. Implications: Knowledge on causes and of early predictions of outcome is needed to give appropriate advice to families, professionals and society, and to develop preventive programs.
NCT00591747
Women aged 50 and older are disproportionately affected by breast cancer, not only in terms of new diagnoses, but also in terms of survivorship. Approximately 85% of women who receive a first diagnosis of breast cancer are aged 50 and over, thus older women constitute the largest group of breast cancer survivors. Yet, few studies have focused on evaluating whether physical activity and exercise interventions affect long-term symptoms, physical fitness and function, and body composition of older breast cancer survivors. Due to the combined effects of breast cancer, related treatments and aging it is likely that exercise is even more beneficial for older breast cancer survivors than for younger survivors. Along with the cancer-related symptom of fatigue common to cancer survivors, older survivors face age-related declines in bone and muscle mass, muscle strength, bone health and physical function (gait and balance) that are likely exacerbated by reduced physical activity in survivorship and side effects of adjuvant cancer treatment. All women, regardless of age, are at risk for breast cancer recurrence. Recent epidemiologic evidence suggests a link between exercise and reduced risk of cancer recurrence in breast cancer survivors. Strength training is specifically suited to reverse or slow age-related declines in bone, muscle, strength and function and has shown promise to reduce cancer-related fatigue. However, no controlled trials of strength training in older breast cancer survivors have been conducted.
NCT00659906
The purpose of this study is to conduct a 12-month randomized controlled trial comparing the effects of strength training exercise to stretching and relaxation exercise (control) on body composition (bone, muscle and fat mass), energy balance, bone turnover, and physical function (strength, power, gait, balance and self-report physical function and symptoms) in women who experienced premature menopause from chemotherapy for breast cancer.
NCT01870557

Participants: 100 type 1 diabetics and 100 type 2 diabetics recruited from outpatient clinics at Aalborg, Aarhus and Odense, general practitioners and flyers.
NCT00301353
Osteoporosis is a major health problem. It was hypothesized that isoflavone-containing products may be a potential alternative to HRT for preventing bone loss during the menopausal transition. We investigated whether one-year consumption of isoflavone-enriched foods affected bone mineral density, bone metabolism and hormonal status in early postmenopausal women in a randomized double-blind, placebo controlled parallel multi-centre trial.
NCT02445664
Osteoporosis is a highly prevalent disease in which non-adherence is a well-recognized problem. Non-adherence may be due to patients´ lack of knowledge, understanding, and involvement. In this study the investigators aimed to determine the effect of an educational video displayed on a tablet-device. The investigators hypothesized that an educational video would increase patients´ knowledge on osteoporosis and treatment at a two week follow up.
NCT01387672
Purpose: NABT: To compare five widely available nitrate formulations: (1) 15 of nitroglycerin (NTG) ointment, (2) 0.3 mg and (3) 0.6 mg of sublingual NTG, (4) 20 mg of isosorbide mononitrate (an oral tablet), and (5) 160 mg of glycerol trinitrate (a patch), for their efficacy on markers of bone formation and resorption and for the incidence and severity of headache they cause. Hypothesis: There is one ideal nitrate preparation which balances the clinical efficacy in bone remodeling against the common side effect of headache. NABT-B: To determine if nitrates affect markers of bone formation (serum BALP and P1NP) and resorption (serum CTX and urine NTX) in women who have recently discontinued treatment with alendronate, risedronate or zoledronate.
NCT00767299
The study is for Korean women who are postmenopausal and also suffer from osteoporosis. The study will test if women who are given 20 mg of arzoxifene once a day for six months have a less severe level of osteoporosis than those women who do not take arzoxifene. All patients will receive 500 mg of elemental calcium and 400 to 600 IU Vitamin D daily starting 4 weeks prior to study drug administration continuing through the 6 months of therapy.
NCT01397955
This study is a regulatory post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Julina for postmenopausal osteoporosis. The objective of this study is to assess safety and efficacy of using Julina in clinical practice. A total 100 patients will be recruited and followed 3 years since starting Julina administration.
NCT02416947
This study is designed to study the dose response effect of continuous Soluble Corn Fiber (SCF) intake over a 50 day period on bone resorption in healthy post menopausal women using the 41Calcium methodology. To further understand the dose response effect of SCF bone biomarkers will be studied. Our hypothesis is that soluble corn fiber will reduce bone resorption in a dose dependent manner in comparison to placebo when estimated by urinary 41Calcium excretion as well as bone biomarkers of resorption.
