Racial and ethnic disparities in colorectal screening exist among the Medicare population, but researchers do not know whether these disparities differ across geographic regions.
To find out, Thomas Semrad, MD, of the University of California Davis led a team that examined colorectal cancer screening among Medicare enrollees within eight U.S. states. Individuals were considered up-to-date on screening if they had fecal occult blood testing in the prior year or sigmoidoscopy or colonoscopy in the prior five years.
There was little geographic variation in up-to-date status among whites, who were consistently more likely to be up-to-date on screening than other races (except in Hawaii). White versus non-white up-to-date status varied significantly across regions for blacks and Asian/Pacific Islanders but not Hispanics. While white versus black differences in up-to-date status were greatest in Atlanta, rural Georgia, and the San Francisco Bay Area (range: 10 percent to 16 percent differences), there were no significant white versus black differences in Connecticut, Seattle, or Iowa.
Whereas Asian/Pacific Islanders had significantly lower up-to-date prevalence than whites in Michigan, San Francisco, Los Angeles, and San Jose (range: 4 percent to 15 percent differences), Asian/Pacific Islanders in Hawaii had higher up-to-date status than whites (52 percent versus 38 percent). White versus Hispanic differences were substantial but homogeneous across regions (range: 8 percent to 16 percent differences).
The authors concluded that variations in racial and ethnic disparities in colorectal cancer testing among Medicare patients stems principally from regional differences in testing among non-whites. "This finding highlights the need to understand the regional determinants of health care provision for non-white groups," said Dr. Semrad. He noted that the overall proportion of Medicare enrollees who are up-to-date on colorectal cancer screening remains poor and that significant work needs to be done to improve overall screening rates in addition to closing disparities in screening rates amongst racial and ethnic groups.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
