A national survey finds most physicians believe Medicare reimbursement is inequitable, but there appears to be little consensus regarding proposed reforms, according to a report in the October 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

LOS ANGELES (STRICTLY EMBARGOED UNTIL 3 PM CDT ON OCT. 25, 2010) – Neighborhood barbers, by conducting a monitoring, education and physician-referral program, can help their African-American customers better control high blood pressure problems that pose special health risks for them, a new study from the Cedars-Sinai Heart Institute shows.
An international team of researchers based at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, including a physical anthropology professor at Washington University in St. Louis, has discovered well-dated human fossils in southern China that markedly change anthropologists perceptions of the emergence of modern humans in the eastern Old World.
The research was published Oct. 25 in the online early edition of the Proceedings of the National Academy of Sciences.
CHICAGO, Oct. 25, 2010 – Young children who consume substantial amounts of fluoride through infant formula and other beverages mixed with fluoridated water or by swallowing fluoride toothpaste have an increased chance of developing mild enamel fluorosis, according to research published in the October issue of The Journal of the American Dental Association and supported by the National Institute of Dental and Craniofacial Research.
While most commonly associated with mononucleosis, Epstein-Barr virus (EBV) has been linked to many diseases that affect people long after the initial infection takes place, including some forms of cancer. In the current issue of the Journal of Biological Chemistry, scientists at The Wistar Institute describe how viral microRNA – small segments of RNA that suppress the effects of gene activity – allows EBV to hide within cells and evade the immune system.
WEST LAFAYETTE, Ind. - Pathogenic listeria tricks intestinal cells into helping it pass through those cells to make people ill, and, if that doesn't work, the bacteria simply goes around the cells, according to a Purdue University study.
UBC researchers have identified the world's largest marine virus--an unusually complex 'mimi-like virus' that infects an ecologically important and widespread planktonic predator.
Cafeteria roenbergensis virus has a genome larger than those found in some cellular organisms, and boasts genetic complexity that blurs the distinction between "non-living" and "living" entities.
Those who are proud to have a piece of amber that holds a little animal trapped in it maybe should not continue to read this. For what can be seen in the millions of years-old tree resin is almost always just a paper-thin façade. If sliced down the middle, you would find no more than a hollow space covered in some sort of "insect photo wallpaper."
Turning up the heat might be the best thing for athletes competing in cool weather, according to a new study by human physiology researchers at the University of Oregon.
Published in the October issue of the Journal of Applied Physiology, the paper examined the impact of heat acclimation to improve athletic performance in hot and cool environments.
Thanks to a microwave oven, the fundamental nanotechnology process of self assembly may soon replace the lithographic processing use to make the ubiquitous semi-conductor chips. By using microwaves, researchers at Canada's National Institute for Nanotechnology (NINT) and the University of Alberta have dramatically decreased the cooking time for a specific molecular self-assembly process used to assemble block copolymers, and have now made it a viable alternative to the conventional lithography process for use in patterning semi-conductors.
Men with prostate cancer who take anticoagulants like aspirin in addition to radiation therapy or surgery may be able to cut their risk of dying of the disease by more than half, according to a large study presented on November 3, 2010, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO) in San Diego. The study involved more than 5,000 men with localized cancer whose disease had not spread beyond the prostate gland.
Men treated for prostate cancer who were diagnosed after the start of routine screening had a significantly reduced risk of the disease spreading to other parts of the body (metastases) within 10 years of treatment, compared to men who were treated prior to the use of routine screening, according to the first study-of-its-kind presented November 1, 2010, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO).
Prostate cancer patients who are treated with a combination of hormone therapy and radiation have a substantially improved chance of survival compared to patients who do not receive radiation, according to interim results of the largest randomized study of its kind presented at the plenary session, November 1, 2010, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO).
Men with prostate cancer treated with a specialized type of radiation called intensity modulated radiation therapy (IMRT) have fewer gastrointestinal complications compared to patients treated with conventional three-dimensional conformal radiotherapy (3D-CRT), according to a study presented November 1, 2010, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO).
Adding chemotherapy to radiation therapy for muscle invasive bladder cancer allows 67 percent of people to be free of disease in their bladders two years after treatment. This compares to 54 percent of people who receive radiation alone, according to the largest randomized study of its kind presented at the plenary session, November 1, 2010, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO).
