In a study scheduled for publication in the February 2009 issue of The Journal of Urology, researchers report that for low-income men, the opposite is true, with more men undiagnosed until their cancers had reached more advanced stages.
Examining the records of 570 disadvantaged men from the California IMPACT (Improving Access, Counseling and Treatment for Californians with Prostate Cancer) program designed to provide high-quality care for prostate cancer patients, the authors from the University of Michigan, University of California, Los Angeles, UCLA’s Jonsson Comprehensive Cancer Center and the Veterans Administration, Greater Los Angeles Healthcare System, found that 19% of these men had metastatic cancer at diagnosis, in contrast to approximately 4% of men from the general population tracked in other studies. Further, the diagnosis rate for low-risk, less advanced cancers in the IMPACT patients did not increase, also in contrast with a significant rise in these diagnoses in the more affluent population.
The proportion of men in the program presenting with metastatic cancer did not change over time, indicating that low-income men were not receiving prostate cancer screening services that have been shown to reduce the diagnosis of late-stage cancers in the general population.
Writing in the article, David C. Miller states, “Our principal findings clarify some of the challenges (and opportunities) faced by public assistance programs designed to reduce cancer related disparities. Without question IMPACT enables eligible men to receive previously unattainable—and high quality—prostate cancer care…However, from a population perspective the persistent preponderance of metastatic and higher risk localized cancers suggests that more comprehensive strategies are needed to eradicate socioeconomic disparities in prostate cancer specific morbidity and mortality. …” while much attention now focuses on potential overdiagnosis and overtreatment of men with screen detected prostate cancer, our findings serve as a reminder that for disadvantaged men underdetection and undertreatment of prostate cancer remain significant concerns.”
In an accompanying editorial, M. Norman Oliver of the University of Virginia School of Medicine comments that men from minority groups who live in poverty and are diagnosed with prostate cancer are more likely to die of their disease than those men with a higher socioeconomic status. He writes, “However, we must address more than socioeconomic disparities in prostate cancer care…African-Americans have a disproportionately high rate of poverty with some 25% living below the federal poverty level compared to 8% of the white population in that category. This racial disparity in combination with the socioeconomic disparity already discussed places African- American men diagnosed with prostate cancer at an even greater risk of presenting with incurable disease.”

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...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
