Active clinical trials for "Osteoporosis"

Inflammation increases with aging and is implicated in the reduction of bone mass, muscle mass, and strength. Resistance training is safe and effective for increasing muscle mass and strength in older adults,however resistance training by itself cannot suppress inflammation. Ibuprofen is a non-steroidal anti-inflammatory drug that may provide benefits to muscle mass and strength when given after resistance training sessions in older adults; however, more evidence is required to confirm effects across the lifespan. The objectives are to determine the effect of 9 months of exercise training and ibuprofen supplementation, compared to placebo, in older women (≥65years)on the following dependent variables: bone density, geometry, and architecture muscle mass and strength balance

The primary purpose of this study was to evaluate the efficacy of oral calcitonin (rsCT)tablets in the prevention of bone loss in postmenopausal women with lower bone mineral density at increased risk of fracture. The secondary purpose of this study was to determine if there is any food effect by comparing the efficacy and safety of oral calcitonin tablets administered at dinner or at bedtime.

The main objective of this study is to target risk factors for falling, such as improved quadriceps muscle strength,balance and bone mineral density (BMD), to reduce the risk of osteoporotic fractures. Furthermore, to improve quality of life for patients with osteoporosis through an active rehabilitation program. Sub-goals: To assess the effect of active rehabilitation on risk factors for osteoporotic fractures (muscle strength, bone mineral density, balance and frequency of falling) in women with low bone mineral density (BMD)(t-score<1.5) and radius fracture? To assess how active rehabilitation affect the quality of life of women with low bone mineral density(BMD) (t-score<1.5) and radius fracture?

Soluble corn fiber (SCF) has been shown to enhance calcium utilization and bone properties in rats and in adolescent boys and girls.

This pilot study evaluates the effect of theory menu-based mini-videos on vitamin D adherence in older adult with osteoporosis. Half of participants will watch the videos while the other half will receive usual care (treating physician advice).

Optimal calcium retention is important for building bone mass within the genetic potential, a key to reducing risk of osteoporosis later in life. Calcium retention is high during the rapid growth period. The investigators know that urinary calcium is affected by sodium intake but the investigators do not know the effects of sodium intake during the growth spurt or the differences in calcium retention between blacks and whites. Our hypothesis was that a high dietary sodium increases the calcium intakes required for optimal calcium retention in both black and white adolescent girls. The investigators tested calcium retention while girls consumed a low and high sodium diet during three week periods. The subjects were housed in a Purdue fraternity house during the summer and they were supervised at all times by trained staff. During the summer of 1999, subjects consumed diets with 2 levels of dietary Na+ with a fixed diet low in calcium. On the next summer, they switched to a high calcium diet. Subjects collected fecal and urine daily for 20 days. Other measurements included daily body weight, blood pressure every other day, blood sample at the end of each session. Baseline measures included bone mass, self-assessment of pubertal development, a physical examination and diet history.

Cardiovascular diseases (CVD) represent the most frequent cause of death among the elderly population. Hypertension, unfavorable lipid profile, obesity and physical inactivity are among the main risk factors for CVD. In contrast, mortality from CVD is inversely related to levels of physical activity, and is lower in individuals who exercise and have higher functional fitness levels. Thus, the Centers for Disease Control and Prevention, the American College of Sports Medicine, and the American Heart Association have recommended 20-30 min of moderate-to-vigorous aerobic training for the elderly, preferably every day or at least 3 days a week in the case of vigorous exercise.The same organizations also suggest the inclusion of resistance training in order to improve functional fitness. Therefore, the purpose of this study was to compare different exercise modalities in long-term changes of CVD risk factors and physical fitness among older adults.

Osteoporosis is a disease characterized by reduced bone mass and increased skeletal fragility, predisposing to an increased fracture risk. The presence of a low trauma fracture is a powerful predictor of future fractures and about 50% of patients with a fragility fracture will suffer a subsequent fracture in the next 10 years (Center Jacqueline R, 2007). Osteoporotic fractures are associated with an increased morbidity and mortality but also high financial costs. However, less than 20% of patients presenting a low trauma fracture receive an appropriate post-fracture osteoporosis management (Little and Eccles, 2010). The hypothesis of a lack of information and an under assessment of consequences by both patients and physicians has been raised to explain this gap between recommended care and usual practices. The aim of the PREVOST program is to assess the efficiency of patient-centered osteoporosis prevention program, after a fragility fracture of the upper limb, to improve post-fracture management of osteoporosis (ie BMD test and / or osteoporosis treatment) in women over 50 years old. This open randomized controlled trial aims to compare the BMD or osteoporosis treatment prescription rate at 6 months after inclusion between two groups: "intervention" receiving information on fracture and osteoporosis (oral and written), phone call reminders and written information to give to their family physician, and "control" receiving usual care without information.

Osteoporosis is defined as a systemic skeletal disease characterised by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. Osteoporosis is a serious public health problem that is responsible for approximately 3 million women with osteoporosis in France, with approximately 150,000 cases per year occurring in vertebral fractures, of which only one third would be diagnosed and 50,000 hip fractures (causing death in 20% of cases). The frequency of the disease increases with age, particularly among women: 10% among women aged 60 years and 20% among women aged 65 and 40% among women aged 75. At menopause, oestrogen deficiency causes alterations of the immune system, decreased bone formation, microarchitectural deterioration and a decrease in bone mass. Various factors may contribute to this decrease in bone density such as diet, lifestyle, or the genetic background. According to prospective studies, an overexpression of 135% of hip fractures is expected at European level in 50 years. Therefore, it is interesting to develop new prevention approaches aimed at maintaining the healthy aging population. Nutritional researches can consider setting up a real prevention. Studies suggest that specific milk protein fraction contain factors able to promote bone formation, inhibit bone resorption in vitro. In animal model, they showed that the specific fraction prevents bone loss in aged ovariectomised rats by reducing bone resorption. Furthermore, in human volunteers, a supplementation with the specific milk protein fraction maintains balanced bone remodelling and increase bone mineral density. For example, in healthy postmenopausal women, it has been reported that a mean rate of gain of lumbar BMD in the MPF group (1.21%) was significantly higher than in placebo group (-0.66%; p<0.05). The objective of this study is to assess the efficacy of daily consumption of the milk proteins fraction on bone mineral density improvement in healthy postmenopausal women.

This study will determine if daily oral intake of 200g of a marketed yogurt with fortified calcium content and a milk basic protein (MBP)80 mg benefits on bone cells activity in postmenopausal women. The efficacy of the product is measured by examining the variation of biochemical markers of bone turnover. MBP 80 is a particular protein contained in milk; it has been added to the yogurt provided for this study. The effects of MBP 80 on the quality of bone tissue have not yet been proven.
