Fewer than half of patients diagnosed with colorectal cancer had received a screening procedure at least six months prior to their diagnosis, according to a new study. Researchers writing in the February 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, further say almost 94 percent of colorectal cancer patients had either not undergone a colonoscopy at all, or not until having the procedure that led to their diagnosis.
Professional societies unanimously recommend colorectal cancer screening in older adults. The premise is mortality and morbidity is reduced when a premalignant growth, which is generally at an earlier stage, is detected and treated. Clinicians can use tests as simple as the fecal occult blood test (FOBT), which is the cheapest but least sensitive test, to tests that examine part of the colon with the sigmoidoscopy, or all of it with a colonoscopy or barium enema. The colonoscopy is the most sensitive test.
In order to characterize the use of the various screening tests in the population and their association with cancer stage, Gregory S. Cooper, M.D. and Jonathan D. Payes, M.S. of the University Hospitals of Cleveland and Case Western Reserve University reviewed the screening history and cancer stage of 5,806 elderly patients diagnosed with colorectal cancer.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
