Filter by:The purpose is to perform a one-year study designed to assess whether treatment of hypovitaminosis D increases intestinal absorption of calcium, subsequent retention of calcium within bone, decreases bone turnover, and favorably impacts upon skeletal muscle mass, functional status, measures of physical function and quality of life. I hypothesize that treatment of hypovitaminosis D results in improved intestinal calcium absorption, greater retention of calcium within the bone reservoir and improved physical function, quality of life and muscle mass.
This is a dose escalation study to determine the maximum tolerable dose of Parathyroid Hormone-related Protein, PTHrP, that can be given safely over one week. The investigators plan to infuse low doses of intravenous PTHrP to determine if it leads to a sustained and progressive suppression of bone formation as occurs in humoral hypercalcemia of malignancy (HHM) or an increase in bone formation as occurs in hyperparathyroidism (HPT). Additionally, the investigators will assess the direct influence of PTHrp on markers of bone turnover, and plasma 1,25 (OH)2 vitamin D regulation in healthy human volunteers.
To develop a decision aid to support the decision to use (or not use) bisphosphonates in postmenopausal women at risk for osteoporotic fractures, and to assess the impact of the decision aid on start and six month adherence to bisphosphonates.
This study is being conducted to collect information from subjects with osteoporosis regarding their experience using the Forteo B Pen to self-administer teriparatide in the community setting. Information collected during this study will be used to assess the need for changes to the Forteo B-Pen User Manual and patient educational tools. Additionally, the information generated from patients during this trial will be reviewed to assess the acceptability of the Forteo B Pen for commercial launch.
The primary objective of this study is to compare the urinary excretion of 14C-labeled risedronate and alendronate over 28 days.
We wish to investigate whether a weekly, 2½ hour group-based osteoporosis education intervention (the Osteoporosis Prevention and Self-Management Course), is different to one session course (1x 2½ hours) on osteoporosis knowledge, confidence to eat calcium-containing foods, confidence to exercise, and amount of exercise undertaken after three and nine months of follow-up in people aged over 50 years who have already had a bone fracture.
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.
The purpose of this study is to test whether strength/weight training exercises enhance the effectiveness of calcium, vitamin D, and risedronate for the prevention and treatment of osteoporosis in postmenopausal breast cancer survivors.
Osteoporosis is a common bone disease in older adults in which the bones become weaker and prone to fracture. Medications are available to slow or even stop disease progression. However, very few adults who are prescribed osteoporosis medications actually follow through with filling their prescriptions and taking the medications. Ways to improve medication use have not been well developed or adequately tested. The purpose of this study is to evaluate a telephone coaching program, with or without helpful adherence notifications to doctors, in improving treatment adherence in older adults who are starting an osteoporosis medication.
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.
