A UCLA/Veterans Affairs study showed that more than 40 percent of patients who initially had received a positive result on a fecal occult blood test (FOBT) -- an initial screening tool for colon cancer -- did not receive appropriate diagnostic follow-up tests such as a colonoscopy or barium enema in 2002. According to the authors, the study may even underestimate this problem in the United States, since previous studies have shown the VAs level of preventive care and follow-up traditionally has been higher than at most other health care settings.
Published in May in the journal Diseases of the Colon & Rectum, the UCLA/VA study is one of the largest reviews of colorectal screening and follow-up patient data to date. The study used data from the VA, the nations largest integrated health care system. The study was performed as a prelude to a national VA effort, now underway, to improve colorectal cancer screening and suggested the need for better medical follow-through for patients with potential colon cancer.
Study authors took advantage of the VAs ongoing quality improvement program to analyze 39,870 patient records. Overall, 61 percent of eligible VA patients had been screened for colorectal cancer, a rate significantly higher than the national average. Of the screened population, 313 patients had an abnormal FOBT result. Only 59 percent, or 185 patients, of this group received follow-up diagnostic tests such as a colonoscopy or a barium enema. Forty-one percent, or 128 patients, received no follow-up at all in the six months following the FOBT.

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...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
