The purpose of this clinical study is to confirm the efficacy and safety of the Kyphon®Xpede™ Bone Cement in human use in China.
This study will assess the pharmacokinetics and safety and explore therapeutic effects with once-weekly recombinant human parathyroid hormone for injection ( 1-34 ) ( G56W1 ) in women with post-menopausal osteoporosis .The anticipated time on study treatment is 24 weeks, and the target sample size is 148 individuals.
Effects of abaloparatide on bone formation and resorption in postmenopausal women with osteoporosis.
Bone disease and adrenal suppression are two of the many side effects of steroid use in pediatrics. Evidence has shown that adrenocorticotropic hormone (ACTH) protects against the adverse bone effects of steroids in animals and in vitro models, but this has not yet been evaluated in humans. The proposed mechanism in these studies is that ACTH stimulates osteoblasts in bone to release Vascular Endothelial Growth Factor (VEGF), which increases the vascularity in high risk areas of bone. This can potentially be protective against osteonecrosis and osteopenia, which can lead to bone fractures if not prevented. The VEGF release can also be used to demonstrate that an administration of exogenous ACTH occurred. This could be important in diagnosing adrenal insufficiency (AI). One of the tests to assess central AI is the low-dose ACTH stimulation test (LDAST). This test has a high rate of false positive results due to technical limitations. However, if an ACTH-stimulated VEGF level can be measured during the test as a marker of the test being done properly, it will allow for proper interpretation of the results (and identification of a false positive), which will reduce the number of patients being incorrectly diagnosed with central AI. This study will recruit ten healthy children and adolescents, ages 9-18, to assess the effects of ACTH on VEGF levels. The investigators will measure the response of VEGF and cortisol to an administration of a low dose and high dose of cosyntropin (the synthetic ACTH analog used in this test). The hypothesis of this study is that VEGF and cortisol will both increase after administration of cosyntropin. At this time, no other studies have demonstrated that VEGF is responsive to ACTH in humans. If the hypothesis is correct, the results will have two main implications. VEGF can be used as a marker of ACTH administration during the LDAST to identify false positive tests. Secondly, this will help further research into whether ACTH can be used to protect against bone disease in high-dose steroid-treated patients. Further studies can be done to assess whether this effect will be the same in patients with AI or steroid-induced adrenal suppression.
This study compared the bone health of KS patients who were actively monitored in our clinic by dual-energy X-ray absorptiometry (DXA) with that of a control group of healthy volunteers.
The aim of this study is to examine the efficacy and adverse events in the following 3 groups in osteoporosis patients: 1. The administration period of teriparatide is less than 6 months and thereafter, denosumab for 24 months. 2. The administration period of teriparatide is from 6 to 12 months and thereafter, denosumab for 24 months. 3. The administration period of teriparatide is more than 12 months and thereafter, denosumab for 24 months.
The process of bone remodeling exhibits pronounced diurnal pattern that is important for bone health. A balanced rate of bone resorption is required to maintain bone health, a balance that can be disturbed during the life-cycle to effect net rate of formation (as occurs during growth and development to adulthood) or net resorption (as occurs, for example, during the menopause). Bone turnover is a nutritionally modulated process and the investigators believe a milk-based protein supplement (MBPS) can modulate beneficially the rate of bone resorption over the time period when bone remodeling is most active i.e. late evening/overnight. In this novel approach to the timing of nutrient ingestion, the proposed nutrient intervention seeks to modify (reduce) the rate of bone resorption and promote the rate of bone formation to the benefit of bone health in this at risk population..
In this nationwide multi center study the investigators combine the low dose chest CT scan data with QCT technology, to measure the BMD of spine, VAT and liver fat in the health check subjects. The aim of this study is to evaluate the performance of QCT in the health check field, and further to evaluate the prevalence of osteoporosis, obesity and liver steatosis in health check population across China.
Background: It is well known that health risks change during lifespan. The weight of a single risk factor increases with aging. The clinical significance of a single risk factor is clear but there is a lack on the effectof multiple risk factors linked together along different hormones condition of women's life in particular regarding to metabolic syndrome, osteoporosis, and thromboembolic risk. Aim: 1) characterization and follow up of cardiometabolic risk in women of childbearing age; 2) characterization and follow up of cardiometabolic risk and osteoporosis in menopausal-transition women and in post-menopausal women;
This study aimed to compare teriparatide treatments and PVPs, focusing on its effects on life qualities and effect/coast ratio and evaluate which method is better for patients.
