Vanderbilt-led study reveals racial disparities in prostate cancer care

2012-08-23
(Press-News.org) A study led by investigators from Vanderbilt-Ingram Cancer Center (VICC), Nashville, Tenn., finds that black men with prostate cancer receive lower quality surgical care than white men. The racial differences persist even when controlling for factors such as the year of surgery, age, comorbidities and insurance status.

Daniel Barocas, M.D., MPH, assistant professor of Urologic Surgery, is first author of the study published in the Aug. 17 issue of the Journal of Urology.

Investigators from VICC, the Tennessee Valley Veterans Administration Geriatric Research, Education and Clinical Center, Nashville, and the Center for Quality Improvement and Patient Safety, Agency for Healthcare Research and Quality, Rockville, Md., were involved in the study of racial disparities.

The researchers analyzed records of 105,972 prostate cancer patients who received radical prostatectomies in all nonfederal hospitals in Florida, Maryland and New York state from 1996 to 2007. Of the patients, 81,112 (76.5 percent) were white, 14,006 (13.2 percent) were black, 6,999 (6.6 percent) were Hispanic and 3,855 (3.6 percent) represented all other races.

Previous studies have found that men who are treated at high volume hospitals (HVH) by surgeons who do a high volume of prostatectomies (HVS) have better outcomes and lower mortality.

In this study, black men had 33 percent lower odds of using a high volume surgeon and 27 percent lower odds of visiting a high volume hospital than white men. Furthermore, black men had a higher rate of blood transfusion and longer length of stay in the hospital. They also were more likely to die in the hospital.

Black men who used HVH and HVS were at substantially decreased risk for adverse outcomes, including death, than those using lower volume health care providers, but still had worse outcomes than their white counterparts.

"Our findings of racial variation in the quality of surgical care for prostate cancer adds to previous studies that have shown racial differences in screening behavior, stage at presentation and use of aggressive treatment, and may contribute to our understanding of why black men have much higher prostate cancer mortality than white men," said Barocas.

The results suggest that black men may have more difficulty gaining access to high quality care.

"Racial disparities in prostate cancer outcomes may be partially explained by differences in access to high quality care, which in turn may reflect differences in patient resources," explained Barocas. "To close this gap, we may need interventions aimed at improving access to high quality care for all men, including access to high volume health care providers."

###Investigators involved in the study include Sam Chang, M.D., Michael Cookson, M.D., Joseph Smith Jr., M.D., David Penson, M.D., MPH, Jay Fowke, Ph.D., MPH, Nathaniel Mercaldo, M.S., Jeffrey Blume, Ph.D., all of Vanderbilt, and Darryl Gray, M.D., ScD., with the Agency for Healthcare Research and Quality.

Funding for the research was provided by the National Institute of Environmental Health Sciences (K12 ES15855), and the National Center for Research Resources at the National Institutes of Health through the Vanderbilt CTSA Grant (UL1 RR024975).

Sensor detects glucose in saliva and tears for diabetes testing
2012-08-23
WEST LAFAYETTE, Ind. – Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine and might be manufactured at low cost because it does not require many processing steps to produce. "It's an inherently non-invasive way to estimate glucose content in the body," said Jonathan Claussen, a former Purdue doctoral student and now a research scientist at the U.S. Naval Research Laboratory. "Because it can detect glucose in the saliva and tears, it's a platform that might eventually help to eliminate or reduce ...

Field guide to the Epstein-Barr virus charts viral paths toward cancer
2012-08-23
Researchers from The Wistar Institute and Memorial Sloan-Kettering Cancer Center (MSKCC) have teamed to publish the first annotated atlas of the Epstein-Barr virus genome, creating the most comprehensive study of how the viral genome interacts with its human host during a latent infection. Epstein-Barr virus (EBV), which is thought to be responsible for one percent of all human cancers, establishes a latent infection in nearly 100 percent of infected adult humans. The atlas is designed to guide researchers toward new means of creating therapies against EBV-latent infection ...

For mitochondria, bigger may not be better

2012-08-23
Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the development of neurodegenerative diseases such as Alzheimer's. "There had been a fair amount of interest in mitochondria in Alzheimer's and tau-related diseases, but causality was unknown," said Brian DuBoff, first author of the study ...

Their research is published in the ...

Cancer survival in Germany after the fall of the Iron Curtain

2012-08-23
Data from the 1970s and 1980s show that people affected by cancer survived significantly longer in West Germany than cancer patients behind the Iron Curtain. Looking at a diagnosis period from 1984 to 1985 in the former German Democratic Republic, 28 percent of colorectal cancer patients, 46 percent of prostate cancer patients, and 52 percent of breast cancer patients survived the first five years after diagnosis. By contrast, 5-year survival rates for people in West Germany affected by these types of cancer were 44 percent, 68 percent, and 68 percent in the years from ...

Past tropical climate change linked to ocean circulation, says Texas A&M team

2012-08-23
A new record of past temperature change in the tropical Atlantic Ocean's subsurface provides clues as to why the Earth's climate is so sensitive to ocean circulation patterns, according to climate scientists at Texas A&M University. Geological oceanographer Matthew Schmidt and two of his graduate students teamed up with Ping Chang, a physical oceanographer and climate modeler, to help uncover an important climate connection between the tropics and the high latitude North Atlantic. Their new findings are in the current issue of PNAS (Proceedings of the National Academy ...

IBC 2012: New standard HEVC encodes films more efficiently

The opening ceremonies for the Olympic Games captivated countless viewers all over the world in front of their televisions, astounding them with a gigantic show. Relatively few people were able to have a live experience of the spectacle at the London stadium. Still, some of the fans watching the show felt as if they were there live, even though they were only sitting in front of a large cinema screen. That's because a few movie theaters showed the opening ceremonies in 8K-resolution, which corresponds to 33 megapixels. The resolution on home televisions will soon be enhanced ...

AGU: Link found between cold European winters and solar activity

2012-08-23
WASHINGTON – Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Yet records of average, seasonal temperatures do not date back far enough to confirm any patterns. Now, armed with a unique proxy, an international team of researchers show that unusually cold winters in Central Europe are related to low solar activity – when sunspot numbers are minimal. The freezing of Germany's largest river, the Rhine, is the key. Although the Earth's surface overall continues to warm, the new analysis has revealed a correlation ...
