DURHAM, N.C. -- After swabbing the cheeks of more than 200 lemurs and related primates to collect their DNA, researchers at the Duke Institute for Genome Sciences & Policy (IGSP) and Duke Lemur Center now have a much clearer picture of their evolutionary family tree.
CHAPEL HILL Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. But as concern about drug-resistant bacteria grows, one novel approach under way at the University of North Carolina at Chapel Hill seeks to thwart the bug without a drug by taking a cue from nature.
BUFFALO, N.Y. -- Up to 20 percent of patients taking aspirin to lower the risk of suffering a second cerebrovascular event do not have an antiplatelet response from aspirin, the effect thought to produce the protective effect, researchers at the University at Buffalo have shown.
Millions of people use low-dose aspirin either for prevention of a second stroke, second heart attack or second episode of peripheral artery disease, said Francis M. Gengo, Pharm.D., lead researcher on the study.
DURHAM, N.C. Conventional wisdom holds that as the U.S. population ages, the incidence of heart failure will continue to rise. A new study from Duke University Medical Center challenges part of that assumption, however, finding that heart failure is actually declining among the very elderly. Yet the number of heart failure cases overall continues to rise.
TORRANCE Combined hormone therapy appears to increase the risk that women will have abnormal mammograms and breast biopsies, and it may decrease the effectiveness of both methods for detecting breast cancer, according to a report in the Feb. 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
The number of elderly individuals newly diagnosed with heart failure has declined during the past ten years, but the number of those living with the condition has increased, according to a report in the February 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Patients who develop a blood clot in their legs (deep vein thrombosis) or lungs (pulmonary embolism) are at risk for experiencing another blood clot within three years, and patients with pulmonary embolism have a higher risk of death, according to a report in the February 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Combined hormone therapy appears to increase the risk that women will have abnormal mammograms and breast biopsies and may decrease the effectiveness of both methods for detecting breast cancer, according to a report in the February 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Hormone therapy use remains common among women beginning menopause, according to background information in the article. For women with a uterus considering combined estrogen plus progestin use, identified breast cancer issues represent a concern, the authors write.
Antibiotics appear to be frequently prescribed to individuals with advanced dementia in nursing homes, especially in the two weeks before death, according to a report in the February 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
More than 5 million Americans have dementia, according to background information in the article. About 70 percent of them will live in nursing homes at the end of their lives. Recurrent infections and fever are common among these patients, who may receive antibiotics to treat these conditions.
ST. LOUIS -- A sophisticated robotic dog could be a good companion for your dog-loving grandmother who cant care for a living pet, a new Saint Louis University study suggests.
The researchers compared how residents of three nursing homes interacted with Sparky, a living, medium-sized gentle mutt, and Aibo, a doggie robot once manufactured by Sony that looks like a three-dimensional cartoon.
