Filter by:This proposed study was designed to investigate the prevalence of a 5-year incident osteoporotic fracture and evaluate the association of a 5-year change of 25-hydroxyvitamin D (25[OH]D)/bone turnover makers/bone mineral density (BMD) with the incident fracture in the Chinese postmenopausal women, based on an endeavor of a 5-year post-baseline follow-up visit of a previous cross-sectional study, PK-VF, in which 1724 participants were enrolled and examined.
In Switzerland, the prevalence of vertebral fractures in community- dwelling women is unknown and the published data from the Swiss hospitals statistics represent only the tip of the iceberg. In addition, the percentages of women correctly identified with vertebral fractures due to osteoporosis and the treatment rate of these women with a drug proven to reduce the risk of further fractures are unknown. Furthermore, it is not known whether the prevalence of vertebral fractures differs between urban and rural areas or between mountain areas and plain country, e.g. due to possible differences in sun exposure (vitamin D production) and/ or in physical activity and/ or dietary habits. Clinical signs and symptoms leading to the suspicion of vertebral fracture(s) lack either sensitivity (wall-occiput distance) or specificity (rib-pelvis distance). Whether a combination of both would improve sensitivity and specificity is unknown. The gold standard for the diagnosis of vertebral fracture relies on antero-posterior and lateral X-Rays of the thoracic and lumbar spine. Despite standardization of X-Ray readings, a retrospective study of hospitalized elderly patients has shown that as many as 50% of the radiographic reports failed to note the presence of moderate to severe vertebral fractures. In a primary care setting, fewer than 2% of the women received diagnoses of osteoporosis or vertebral fracture, although expected prevalence is 20% to 30% and appropriate drug treatment was offered to only 36% of the diagnosed patients. The recent availability of software for vertebral fracture assessment (VFA) coupled to DXA measurements allows for the detection of vertebral deformities, which is critical for management of osteoporosis, as the existence of such deformities substantially increases the risk of subsequent fracture. Recently published results show that VFA allows the diagnosis of a vertebral fracture. The sensitivity of VFA for detection of vertebral fractures compared to expert radiologist reading of X-ray is excellent for grade 2 and 3 fractures, ranging between 90-94%.
The aim of this study was to investigate the levels of RANKL and Osteoprotegerin, and their relationship in gingival crevicular fluid of post-menopausal women with osteoporosis/osteopenia and chronic periodontitis simultaneously and evaluate the effect that the use of bisphosphonates in periodontal disease. Study hypothesis: "The osteoporosis / osteopenia in postmenopausal women patients with periodontal disease affect the ratio RANKL / OPG in gingival crevicular fluid samples favoring osteoclastogenesis processes "
The aim of the study is to assess the effect of an antiresorptive medication in combination with standard dose or alternate dose teriparatide. The study extension will evaluate the effect of one-dose of zoledronic acid after the teriparatide/denosumab combination.
This study will compare the effect of denosumab produced by two different manufacturing processes on bone mineral density at the lumbar spine in postmenopausal women with osteoporosis.
As a tertiary hospital the Traumatology department at the Kantonsspital Aarau looks after about 500 fracture patients hospitalized with an age over 50 years a year. First, we were interested in the effective rate of osteoporotic fractures in this cohort. As to this objective we offered subsequent diagnostics in suspected patients. 2012 we introduced a diagnostic pathway for every patient over 50 years of age with a fracture, including dual energy x-ray absorptiometry (DXA), a questionnaire about risk factors concerning osteoporosis and risk of fracture, the WHO Fracture Risk Assessment Tool (FRAX) and a laboratory workup focusing on this topic. Considering all these information we sent a detailed therapy-plan to the responsible General practitioner. The main goal of this study is to verify the persistence and compliance of the osteoporosis therapy 12-15 months after fracture and to clarify any obstacles potentially impeding therapy (prejudice, adverse events, contraindication overlooked, financial problems etc.). The investigators use a postal questionnaire provided to the patient and the general practitioner. Data collection is undertaken by a study nurse, in addition phoning for missing data by phone-call. With the aim to ameliorate the implementation of treatment, patients and general practitioners will be provided with the specifically tailored information found to be missing.
The miRNA plays an important regulation role in gene expression, and also closely related to bone metabolism. Previous research found that postmenopausal osteoporosis with kidney Yin deficiency syndrome (POP) is associated with CLCF1 gene. This project proposed by bioinformatics prediction CLCF1 targeted regulation of miRNAs, and use the 3 'UTR dual luciferase report system for target validation, aimed at the miRNA levels to explore postmenopausal osteoporosis molecular mechanism with kidney Yin deficiency syndrome.
The purpose(s) of this study is to measure how much of the study drug gets into the blood stream and how long it takes the body to get rid of it when given in multiple doses, subcutaneously (SC) (by inserting a needle just under the surface of the skin in the lower abdominal area), to postmenopausal (PMP) female participants. Information about any side effects that may occur will also be collected. This study will also be looking for special markers called "biomarkers" that can be used to study osteoporosis and/or the effects of the study drug. There will be 2 parts to this study. The first part will last approximately 6 weeks and the second part will last approximately 7 weeks.
The aim of this study is see the changes in bone mineral density after discontinuation or stop the use of bisphosphonates and make the switch to bazedoxifene).
The purpose of this study is to compare 2 formulations of romosozumab (AMG 785) on bone mineral density (BMD) in postmenopausal women with osteoporosis.
