Active clinical trials for "Osteoporosis"

This study aims to create a database of patients with stable and chronic heart failure with comprehensive assessment of bone, skeletal and vascular status. RoC-HF will facilitate cross-sectional and, eventually, longitudinal mechanistic epidemiological analyses to disentangle the role of the bone- vascular axis in chronic heart failure. Blood and urine samples will be stored to facilitate future biomarker analyses.

This study, which was designed as a prospective observational study, was planned to enroll 75 female patients with postmenopausal osteoporosis who had been using bisphosphonates for more than two years and did not respond to treatment. 2 doses of denosumab were administered to the patients every 6 months. Bone mineral density of patients were measured with DEXA at the beginning and end of the study. A total of 66 patients completed the study. At the end of the study, there was a significant improvement in the femur and lumbar total bone mineral density of the patients compared to the baseline. However, no statistically significant difference was found in terms of the frequency of new fractures.

Is to investigate the relation between 14-3-3η protein, disease activity, and bone mineral density in female patients with rheumatoid arthritis.

The risk for a subsequent fracture is significantly higher in patients presenting with a fracture compared to individuals without a previous fracture and is highest within the first 2 years after the initial fracture. The risk for a subsequent fracture is not dependent of BMD as measured by conventional DXA. In recent studies, it has been shown that HRpQCT measurements provide information about bone structure, bone quality and bone strength in addition to BMD measurements. Diagnostic strategies should be focussed on bone quality and bone strength and fall prediction in the patients at high risk for falls, subsequent fracture and mortality such as patients with a recent fracture. Therefore, the investigators conduct a prospective observational study in 500 patients aged 50 years and older who present with a clinical fracture for evaluation of bone strength, physical activity, falls, subsequent fractures and mortality during a follow-up period of 3 years.

A large-scale, community-based, cross-sectional study was conducted to evaluate the extent to which lifestyle was associated with osteoporosis among the Chinese population by using self-reported questionnaire methods.

This observational study will provide an opportunity to document local patterns of susceptibility, patient profile, and usefulness of screening in postmenopausal patients coming to gynecology outpatient clinics in Pakistan. This will also capture the initial management of PMO in diagnosed patients. The information gathered will serve as a foundation for developing national guidelines on screening and management of PMO in Pakistan.

Gaucher disease is a most common genetic metabolic disease characterized by low platelet number, liver and spleen enlargement and various forms of bone diseases including low bone mineral density leading to brittle bones. Various treatment options are now available for this disease. The purpose of this research study is to determine the prevalence of Gaucher disease in patients with low bone mineral density as observed by DEXA scan, which is a form of X-Ray of the bone.

The purpose and objective of this study is to determine the changes in bone metabolism after bariatric surgery in postmenopausal women. This is a prospective cohort study that will enroll up to 40 postmenopausal female subjects with class II and III obesity from the Duke Center for Metabolic and Weight Loss Surgery. The study team will enroll subjects that are already being scheduled for either sleeve gastrectomy or Roux-en-Y gastric bypass. The osteoclast activity, the osteoblast activity, and the bone mineral density will be measured in all subjects preoperatively and 12 months postoperatively through research specific blood tests and Dual energy x-ray Absorptiometry (DEXA) scans. The primary endpoints are change in osteoclast activity as measured by C-terminal telopeptide of type I collagen and change in bone density as measured by DEXA scan. These are continuous variable and given the small sample size the investigators will use a nonparametric Wilcoxon rank-sum test to compare the difference in one year change in these variables. There is a slight risk of loss of confidentiality. Every effort will be made to protect all PHI. There is also the risk of increased exposure to radiation from the DEXA scans performed twice with each subjects participating in the study.

The frequency of osteoporosis in Japan is increasing. Also, the frequency of osteoporosis-based fractures in postmenopausal women is increasing. Therefore, it is urgently required to improve osteoporosis. Life expectancy in Nagano prefecture is the longest in Japan, however, healthy life expectancy in Nagano is not very long in Japan. There are several problems in this issue from the medical site and the patient site. The aim of this study is, from the patient site, to increase the motivation of postmenopausal women for osteoporosis using osteoporotic diagnostic kit.

The DeFRA questionnaire is a new validated algorithm derived from FRAX. Here we use the DeFRA as a "primary anamnestic from" to identify subjects at risk of osteoporosis in a population never screened before and never treated for this disease.
