Filter by:Aim: to examine the effect of an exercise intervention for preventing osteoporosis among postmenopausal women. Objectives: To examine whether mean values for Broadband Ultrasound Attenuation (BUA) using Quantitative Ultrasound (QUS) among postmenopausal women following an eight-month exercise intervention (and at 3-month follow up), will be significantly higher than those obtained pre-intervention. To examine whether mean BUA values among postmenopausal women following an eight-month exercise intervention (and at 3-month follow up) will be significantly higher than mean values obtained from participants in a control group undertaking sham exercises for an equivalent duration. To examine the feasibility of the eight-month exercise intervention for a potential larger study (larger sample size, increased number of trial arms and increased outcome measures), in terms of recruitment, adherence, perceptions, barriers, and acceptability.
Older adults having chronic kidney disease (CKD) have a higher rate of fracture than those without chronic kidney disease. Osteoporosis and chronic kidney disease mineral and bone disorder (CKD-MBD) are risk factors for skeletal fractures. In addition, CKD-MBD is also a risk factor for cardiovascular disease. Pharmacological and non-pharmacological therapy are both important to prevent complications of chronic kidney disease and osteoporosis. Therefore, a prospective intervention study is purposed to investigate the effect of a multifaceted intervention including exercise, diet modification, and pharmacological therapy on their outcomes. Patients who are older than 50 years old and have chronic kidney disease G3-G4 (estimated glomerular filtration rate > 20 ml/min per 1.73 m2) with a high risk of fracture (screening by Fracture Risk Assessment Tool (FRAX®)) are enrolled. Baseline questionnaire, clinical, laboratory and radiological examination are performed. If CKD-MBD or osteoporosis are revealed, the intervention will be given accordingly. All examinations will be repeated every 3 months, except bone mineral density and x-ray film for the spine to investigate the effect of the intervention. After one-year, primary outcomes including mortality, cardiovascular events, subsequent fracture, and fall rate will be examined. The secondary outcomes include changes in biochemistry laboratory data before and after interventions (pharmacological therapy and lifestyle modifications). The bivariate analysis will be performed using the t-test or Mann-Whitney U test for continuous variables with normal or non-normal distribution, respectively. Chi-squared test for categorical variables will be used to test correlations between baseline characteristics, change of laboratory results and outcomes. The paired t-test will be used to examine the difference between before and after the interventions. Stepwise multivariate logistic regression models will be used to identify the correlates of outcomes after adjusting for potential confounders.
Osteoporosis has a devastating impact on quality of life of postmenopausal women, and is a significant cause of disability and morbidity. Many drugs are approved for the prevention and treatment of osteoporosis, but are associated with high costs and side effects. Some data from animal studies suggests that supplementation with probiotics can safely treat and prevent osteoporosis. The probiotic VSL#3 is commercially available, is safe for human consumption, and has been widely used in human clinical trials, and has known health-promoting effects in both children and adults. The double-blind, randomized, placebo-controlled trial of VSL#3 will be conducted for 12 months in 40 postmenopausal women to determine if VSL#3 improves bone mineral density and related bone markers. Study visits will include all or some of the following procedures: a medical exam, urine collection, height and weight measurement, a blood draw to assess bone biomarkers, a DEXA (dual energy X-ray absorptiometry) scan to measure bone density, and health questionnaires. This is one of the first clinical trials proposed to investigate the effects of probiotics in bone in humans. If successful, this proposal will provide the first evidence that nutritional supplementation with the probiotic VSL#3 is a safe and effective strategy for preventing postmenopausal bone loss.
The purpose of this study is to evaluate the tolerability of two different formulations of blosozumab in women who have reached menopause. This study will last approximately 12 weeks for each participant, not including screening. Screening is required within 28 days prior to starting the study.
This is a multi-center, randomized, double-blind, double-dummy study designed to compare the effects of risedronate, raloxifene, and placebo on BMD, bone turnover markers, and other markers of anabolic activity in postmenopausal women who previously received HRT.
The purpose of the event-driven base study is to determine the safety and efficacy, especially fracture risk reduction, of odanacatib in postmenopausal women diagnosed with osteoporosis. In a placebo-controlled extension of the base study, participants continued to receive the same blinded study medication for a total of up to 5 years of blinded study medication combined between the base study and the extension. After participants received 5 years of blinded study medication, they received open-label odanacatib through the end of the first extension. Participants were then invited to enroll in a second extension study in which they received open-label odanacatib for an additional 5 years. Two imaging substudies (PN032-Base/Extension and PN035) were conducted for participants in the MK-0822-018 Study. Additional safety information was collected for participants who discontinued from the base study or the blinded first extension in an observational follow-up study, MK-0822-083 (EudraCT number: 2007-002693-66) .
