6 Clinical Trials for Various Conditions
Study to demonstrate that the Bone UltraSonic Scanner (BUSS) can aid in detection of osteoporosis and predict prevalent osteoporotic fractures. Measurements derived from the BUSS parameters will be able to discriminate between postmenopausal women with osteoporotic fractures when compared to matched controls without history of osteoporotic fracture.
The goal of this study is to determine whether two new, non-X-ray techniques can discriminate between high-energy fractures of normal bone (trauma) and low-energy fractures (fragility) of osteoporotic bone. The current gold-standard for assessing fracture risk areal bone mineral density (aBMD) by dual energy X-ray absorptiometry (DXA) is not particularly effective at identifying individuals who are at risk of suffering a fracture. Yet, there is a growing population of diabetics and elderly individuals prone to fractures. In effect, the age-related and diabetes-related increase in fracture risk is independent of a person's aBMD. These findings stress the urgency in developing diagnostic tools that can improve fracture risk prediction so that patients can be treated with the appropriate anti-fracture therapies.
This Phase II study is designed to evaluate the potential effects of a novel probiotic supplement on the severity of global menopause symptoms (e.g., psychological, somatic, urogenital symptoms) and on bone health in postmenopausal women.
The objective of this study is to determine whether a new minimally invasive method for in vivo measurement of cortical bone tissue properties can identify those who are at risk for fragility fractures of the hip and radius. The investigators hypothesis is that women with fragility fractures of the hip and radius have altered cortical bone tissue properties compared to non-fracture controls independent of standard clinical tests, such as bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA).
The researchers are trying to compare the effectiveness of Vertebral Fracture Assessment (VFA) in addition to the current standard of care spine x-ray in evaluation pre-liver transplant patients.
Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue leading to bone fragility (i.e., weakness) and an increased risk for fracture. Bone strength is a critical factor in a bone's ability to resist fracture and is clearly an important outcome in studies of osteoporosis. The current standard for assessing bone health and diagnosing osteoporosis is to use dual-energy x-ray absorptiometry (DXA) to quantify the areal bone mineral density (BMD), typically at the hip and spine. However, DXA-derived BMD has limited discriminatory accuracy for distinguishing individuals that experience fragility fracture from those who do not. One well known limitation of DXA-derived BMD is that it does not adequately assay bone strength. There is a critical unmet need to identify persons more accurately with diminished bone strength who are at high risk of experiencing a fragility fracture in order to determine an appropriate therapy. A potential new diagnostic approach to assess skeletal health and improve osteoporosis diagnosis is the use of Cortical Bone Mechanics Technology (CBMT). CBMT leverages multifrequency vibration analysis to conduct a noninvasive, dynamic 3-point bending test that makes direct, mechanical measurements of ulnar cortical bone. Data indicates that CBMT-derived ulnar flexural rigidity accurately estimates ulnar whole bone strength and provides information about cortical bone that is unique and independent of DXA-derived BMD. However, the clinical utility of CBMT-derived flexural rigidity has not yet been demonstrated. The investigators have designed a clinical study to assess the accuracy of CBMT-derived ulnar flexural rigidity in discriminating post-menopausal women who have suffered a fragility fracture from those who have not. These data will be compared to DXA-derived peripheral and central measures of BMD obtained from the same subjects.
