A new analysis showed that increases in bone mineral density (BMD) only accounted for 6 to 12 percent of the reduction in non-vertebral fracture risk that resulted from osteoporosis treatment over three years in postmenopausal women.
Previously, analyses of clinical trial data for three major osteoporosis therapies have shown that increases in BMD account for only a fraction (<1/3) of the total reduction in vertebral fracture risk. These new findings, presented today at ENDO 2003, the 85th annual meeting of The Endocrine Society, support that this is also the case for fractures at nonvertebral sites, such as the hip and wrist.
BMD measurement remains a good tool for evaluating patients who are not on treatment and for identifying patients on treatment who are not responding; however, BMD increases in response to therapy cannot replace fracture reduction as the ultimate goal of osteoporosis therapies and the most clinically relevant endpoint. Although BMD is often used as a surrogate marker of efficacy, this study provides further confirmation that BMD is only one of many factors that contribute to the efficacy of an osteoporosis therapy. "These results underscore the importance of physicians evaluating osteoporosis therapies based upon fracture reduction data," said Nelson B. Watts, MD, presenting author and Director, University of Cincinnati Bone Health and Osteoporosis Center. "Many factors of bone quality are important for strong bones, such as rate of bone turnover, bone microarchitecture, and material properties of bone. Therefore, BMD should not be used to compare fracture efficacy between osteoporosis therapies."

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
