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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
