Active clinical trials for "Osteoporosis"

This is an observational and cross-sectional study on the height loss, kyphosis indicators, bone mineral density and vertebral fractures in Chinese postmenopausal women

Syndromes such as sarcopenia, sarcopenic obesity and osteosarcopenic obesity are commonly seen in older adults. They result from the impairment of muscle, bone and adipose tissue. Thus, they lead to a decrease in quality of life and increase morbidity and mortality. The aim of this study is to report the prevalence of sarcopenia, sarcopenic obesity and osteosarcopenic obesity in community-dwelling outpatient older adults and to investigate the related factors.

The purpose of this study is to evaluate the follow-up of the osteoporotic patient by a physician-pharmacist collaboration.

Evaluate the support of osteoporosis in women over 50 years with severe osteoporotic fractures (hip, vertebral, rib, Humeral, pelvic fractures) in the Nîmes University Hospital taking prediction of treatment of osteoporosis as criterion.

Increased life expectancy has attracted research attention, interested in provide a quality and healthy aging. According to the latest census conducted in 2010 by IBGE, Brazilian population consists of 97,342,162 women, whom estimates 30 million are between 40 and 65 years old, a period that includes the climacteric. Therefore, clinical conditions such as osteoporosis becomes significant, either from public health policy standpoint or in relation to the social aspect, by compromising life quality. Women also suffer more from temporomandibular disorders (TMD) than men, and the beginning of this situation occurs after puberty, with peaks during the reproductive and remission periods after menopause. Female sex hormones involvement in osteoporosis is well established, but their participation in the TMD is still controversial. Thus, this study aims to investigate the role of systemic bone mass in menopausal women as a risk factor for articular TMD, as well as the TMD pain behavior during menopause transition periods (48 to 55 years), postmenopausal (56-65 years) and senescence (65-70 years). Therefore, 100 women attended by the HC - FMUSP Gynecology Division, Climacteric Sector, were clinically evaluated by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), used to obtain diagnoses and their associations, as well as to quantify the TMD pain sensitivity degree through the Craniomandibular Index (CMI), both applied by a single examiner. The bone densitometry provided bone mass data of femoral neck and lumbar spine (L1-L4). The RDC/TMD performance as a diagnostic test also was subjected to analysis, considering the 3.0 Tesla magnetic resonance imaging as reference standard, undergoing 30 women, of 100 assessed, in this imaging exam. After analyzing the results, it was shown that the risk posed by osteopenia was 1.33 (IC95% 1.20 - 1.46), with a risk increase of 0.33, while the risk of osteoporosis showed 1.39 (IC95% 1,20 - 1.23 to 1.55), increased by 0.39. Joint diagnoses predominated (68.0%), while 18.0% muscular diagnoses and 14.0% corresponds to the absence of clinically diagnosable conditions, according to the RDC/TMD. The performance of the RDC/TMD to diagnose articular DTM revealed accuracy of 68.0%, sensitivity of 83.0%, specificity 53.0%, pre-test probability of 52.0%, positive predictive value of 60.0 % and negative 74.0%, positive likelihood ratio of 1.77 and negative 0.32. As for the soreness sensibility in TMD, it was found that aging shows a clear tendency towards its reduction (A =- 4.5, p = 0.0324). Then, the study concluded that the decrease in female sex hormones, peculiar to aging, increases the risk of articular TMD, although this pain disfunction decreases with age. The RDC/TMD can be used for large populations screening, but its indication in clinical practice should be done with caution.

Bone mineral density (BMD) measurement using dual-energy x-ray absorptiometry (DXA) is the current gold standard for osteoporosis diagnosis and therapy monitoring. Like all quantitative tests, there is some variability in BMD results obtained when scanning a person more than once. As such, it is current clinical practice, based on the recommendation of the International Society for Clinical Densitometry, that each technologist perform a precision assessment. This approach consists of scanning 30 people twice; the data from which allow determination of what constitutes a real difference in BMD with 95% confidence. A precision assessment typically evaluates a specific clinic's population, using the age range and genders seen at that clinic. However men generally have larger, but often more arthritic, bones than women which may impact the precision results. Therefore, it is possible that gender-specific precision values should be used in clinical practice, however this issue has never been investigated.

This post marketing observational study will be conducted in a prospective, single country, multicenter format to assess the prevention of generalized bone loss in patients with active rheumatoid arthritis (RA) treated with adalimumab (Humira®) in pragmatic prescribing situations. The investigational sites will be centers with experience in the treatment of RA patients and anti-tumor necrosis factor-alpha (TNF-a) therapy. The investigators will be rheumatologists authorized by the Czech Rheumatologic Society for prescribing biological treatment.

Specific subgroups of children who survive treatment for childhood malignancies have been shown to develop relative osteopenia following chemotherapy and are felt to be at risk for developing osteoporosis later in life due to their inability to reach peak bone mass during childhood.

Patients who have received the appropriate number of years of alendronate or risedronate therapy will be recruited. Each patient will have received baseline BMD measurements performed at the spine and the hip by DXA. Each patient will receive tetracycline to label the bone and then have a transiliac bone biopsy. One year later teh bone label and biopsy procedure will be repeated.

This study analysed and reported on the study data from three similar, risedronate studies, 1996052, 2003073, and 2003096. The objective of the study was to determine the differences in the iliac crest bone histomorphometry and bone quality in postmenopausal women who had received long term therapy with risedronate.
