Second breast cancers may be prevented by moderate doses of radiation therapy to unaffected breast
Date: Jan-28-2014Survivors of breast cancer have a one in six chance of developing breast cancer in the other breast. But a study conducted in mice suggests that survivors can dramatically reduce that risk through treatment with moderate doses of radiation to the unaffected breast at the same time that they receive radiation therapy to their affected breast. The treatment, if it works as well in humans as in mice, could prevent tens of thousands of second breast cancers. The study, conducted by researchers at Columbia University Medical Center (CUMC), was published recently in the online journal PLOS ONE.
Progress reported in national plan for preventing healthcare-associated infections
Date: Jan-28-2014Independent evaluators have found that measurable progress in reducing the rates of some targeted HAIs has been achieved under the umbrella of a national plan to prevent HAIs that was developed by the U.S. Department of Health and Human Services (HHS). The evaluation appears in a special February supplement to Medical Care. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
The lung microbiome: A new frontier in pulmonary medicine
Date: Jan-28-2014The Annals of the American Thoracic Society has released a comprehensive supplement on the 56th annual Thomas L. Petty Aspen Lung Conference entitled "The Lung Microbiome: A New Frontier in Pulmonary Medicine."More than 170 microbiologists, basic respiratory scientists, and pulmonary clinicians traveled from nine countries to convene at the three-day conference, which took place in June 2013 in Aspen, CO.

A key identified to the body's use of free calcium
Date: Jan-28-2014Scientists at Johns Hopkins report they have figured out a key step in how "free" calcium - the kind not contained in bones - is managed in the body, a finding that could aid in the development of new treatments for a variety of neurological disorders that include Parkinson's disease.Appearing online in Nature Chemical Biology, the researchers describe their use of tiny "lights" and chemical "leashes" to unveil how calcium is controlled.
Vitamin D deficiency in pregnancy 'increases preeclampsia risk'
Date: Jan-28-2014Research led by investigators from the University of Pittsburgh Graduate School of Public Health suggests that women who have a vitamin D deficiency in the first 26 weeks of pregnancy are more likely to develop severe preeclampsia. This is according to a study recently published in the journal Epidemiology.Preeclampsia is a potentially life-threatening pregnancy complication that usually occurs after the first 20 weeks of gestation or shortly after birth. According to the Preeclampsia Foundation, around 5-8% of pregnancies are affected by the condition.
Weakened immunity to fungus found in space-raised flies
Date: Jan-28-2014Venturing into space might be a bold adventure, but it may not be good for your immune system. Now a study by researchers at the University of California, Davis and published in the journal PLOS ONE shows how growing up on the Space Shuttle weakened a key arm of the immune system in Drosophila flies.It's well-established that spaceflight affects immune responses, said Deborah Kimbrell, a researcher in the Department of Molecular and Cellular Biology in the UC Davis College of Biological Sciences, who lead the study.

Scientists discover deadly plague cause
Date: Jan-28-2014The Justinian plague and the Black Death are two of the deadliest plagues in human history - both responsible for killing almost half of the European population. Now, an international research team has discovered that both plagues were caused by different strains of the same bacterium.This is according to a study recently published online in The Lancet Infectious Disease.The Justinian plague occurred in the sixth century. It is estimated to have have killed between 30 and 50 million people as it spread across Asia, North Africa, Arabia and Europe.
