Billing claims from health insurance companies can provide insights on the long-term health of kidney transplant patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings indicate that valuable health information can be obtained by analyzing medical insurers' reimbursement documents, a process that is much simpler and cheaper than many other forms of clinical investigation.

Washington, D.C. – The amount of time imaging equipment is in use in outpatient settings does not approach use rates President Obama and the Medicare Payment Advisory Commission (MedPAC) recommend Medicare utilize to calculate reimbursement for imaging, according to data recently collected by the Radiology Business Management Association (RBMA), a national association of business professionals in radiology.

TORONTO, ON – New research by a team of University of Toronto scientists could lead to substantial advancements in the performance of a variety of electronic devices including digital cameras.

Researchers created a light sensor – like a pixel in a digital camera – that benefits from a phenomenon known as multi-exciton generation (MEG). Until now, no group had collected an electrical current from a device that takes advantage of MEG.

In Los Angeles County, being disabled can cost a year's income. That's because the annual cost of in-home care services for seniors living alone is now $319 more than this group's median income of $17,029.

Combine long-term care expenses with other basic expenses, such as food and rent, and a Los Angeles senior living alone will need twice the median income to survive, according to new data released today by the UCLA Center for Health Policy Research and the Insight Center for Community Economic Development.

DURHAM, N.C. – Bioengineers at Duke University have developed a laboratory robot that can successfully locate tiny pieces of metal within flesh and guide a needle to its exact location -– all without the need for human assistance.

The successful proof-of-feasibility experiments lead the researchers to believe that in the future, such a robot could not only help treat shrapnel injuries on the battlefield, but might also be used for such medical procedures as placing and removing radioactive "seeds" used in the treatment of prostate and other cancers.

Researchers at the Max Planck Institute for Chemical Ecology in Jena and their colleagues from the Czech Academy of Sciences in Prague have developed a new method to quickly and reliably detect metabolites, such as sugars, fatty acids, amino acids and other organic substances from plant or animal tissue samples. One drop of blood -- less than one micro liter -- is sufficient to identify certain blood related metabolites.

Computers do not spell the demise of literacy -- in fact, they may help to create one of the most literate and engaged generations the world has seen.

Carl Whithaus, associate professor of writing at UC Davis, will make that argument during a 2-3:15 p.m. session on Saturday, June 20, in room 106 of Wellman Hall at UC Davis, part of a four-day Computers & Writing 2009 conference sponsored by the University Writing Program at UC Davis.

"When the human eye searches for an object it looks globally for the rough location, size and orientation of the object. Then it zeros in on the details," said Jiang, an assistant professor of computer science. "Our method behaves in a similar fashion, using a linear approximation to explore the search space globally and quickly; then it works to identify the moving object by frequently updating trust search regions."

Washington, DC – June 12, 2009 -- The Association for Molecular Pathology (AMP) today released the text of a comment letter it has provided to the Federal Coordinating Council for Comparative Effectiveness Research (CER) in which AMP sets forth its recommendations for priority areas on which to focus CER activities.

Electronic devices of the future could be smaller, faster, more powerful and consume less energy because of a discovery by researchers at the Department of Energy's Oak Ridge National Laboratory.
