Since 1927, obesity has been thought to be a risk factor for fatal pulmonary embolism (PE). Because of the high proportion of obesity in the general population, previous studies have not determined whether obesity is an independent risk factor for PE or deep venous thrombosis (DVT). In an extensive study published in the September issue of The American Journal of Medicine, researchers from St. Joseph Mercy Oakland Hospital, Pontiac, Michigan; Wayne State University, Detroit, Michigan; and Oakland University, Rochester, Michigan; analyzed over 20 years of patient records compiled by the National Hospital Discharge Survey (NHDS) to further investigate the potential risk of obesity in venous thromboembolism. The investigators concluded that obesity is a risk factor for venous thromboembolic disease in men as well as women, particularly those under age 40.
The NHDS is comprehensive in its scope including data on patients of all races and ages obtained annually from 181,000 to 307,000 sampled patient abstracts from 400 to 494 non-Federal short-stay hospitals in 50 states and the District of Columbia. There were more than 12,000,000 obese patients and almost 700,000,000 non-obese patients in the sampled data.
The relative risk of DVT, comparing obese patients with non-obese patients, was 2.50. The relative risk of PE was 2.21. Obese females had a greater relative risk for DVT than obese males, 2.75 versus 2.02. Obesity had the greatest impact on patients aged less than 40 years, in whom the relative risk for PE in obese patients was 5.19 and the relative risk for DVT was 5.20. In females aged less than 40 years, the relative risk for DVT comparing obese with non-obese patients was 6.10. In males less than 40 years of age, the relative risk for DVT was 3.71.

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...
