CHICAGO --- A study published today in the European Heart Journal found no evidence that digoxin increases mortality in patients with atrial fibrillation (AF), the opposite of results just published by another group in the same journal analyzing the same data.

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill (UNC) have developed a new tool to help surgeons use X-rays to track devices used in "minimally invasive" surgical procedures while also limiting the patient's exposure to radiation from the X-rays.
The climate governs the seasonal activity of vegetation; humankind influences it. In the humid mid-latitudes, temperature is the largest influencing factor for plant growth. In predominantly dry areas, however, it is the availability of water and in the high latitudes incident solar radiation. Without a doubt, humankind also has a modifying impact on the ecosystem. Satellites have been recording how the vegetation on the Earth's surface is changing since the 1980s.
PHILADELPHIA - A study led by researchers at the Perelman School of Medicine at the University of Pennsylvania and Boston University School of Medicine has found that nearly one quarter of patients may return to the emergency department within 30 days of being discharged from a hospitalization. None of these emergency room visits that do not lead to subsequent admission are included in calculating hospital readmission rates, which are a key focus of health care cost containment and quality improvement efforts. The findings are published in Annals of Emergency Medicine.
Background checks and college admission questions don't predict criminal behavior (but gun clubs do)
Aurora shooting suspect James Holmes had no problem at all getting into graduate school for neuroscience at the University of Colorado but he was turned down for membership at a local gun club.
A new study published in the American College of Rheumatology (ACR) journal, Arthritis Care & Research, reveals that women with rheumatoid arthritis (RA) who were on methotrexate (MTX), a drug commonly used to reduce inflammation caused by RA, had lower rates of induced abortions compared to women with RA who were not exposed to the medication. Findings indicate that women with RA exposed to anti-tumor necrosis factor (anti-TNF) drugs may have increased abortion rates compared to unexposed women.
The use of social media by older people can offer valuable additional support in cases of sickness and diseases, new research from the University of Luxembourg has shown.
In a new publication, Dr Anja Leist from the University's Research Unit INSIDE, concludes that possibilities for a systematic application in clinical practice seem promising.
Patients' health outcomes improve when physicians individualize care and take their patients' life circumstances into account, according to a new study by the University of Illinois at Chicago and the U.S. Department of Veterans Affairs.
The study is the largest ever to be conducted using real patients to collect data about their doctors' behavior using concealed audio recorders. It appears in the April 16 issue of Annals of Internal Medicine and was funded by the U.S. Department of Veterans Affairs.
Research at Johns Hopkins suggests that if hospitals would show physicians the price of some diagnostic laboratory tests at the time the tests are ordered, doctors would order substantially fewer of them or search for lower-priced alternatives.
INDIANAPOLIS and WEST LAFAYETTE, Ind. -- Information collected from individual patients at doctor's office and hospital visits could be used to improve health care and reduce costs on a national scale, according to a discussion paper released by the Institute of Medicine.
Physicians at the Virginia Commonwealth University Medical Center have become the first in Virginia to successfully implant a telescope in a patient's eye to treat macular degeneration.
ANN ARBOR—The larger the group, the smaller the chance of forming interracial friendships, a new University of Michigan study shows.
Published in the Proceedings of the National Academy of Sciences, the study examines how the size of a community affects the realization of people's preferences for friends. U-M researchers Siwei Cheng and Yu Xie tested their theoretical model using both simulated and real data on actual friendships among 4,745 U.S. high school students.
TORONTO, April 15, 2013—A review of published research has found no evidence that drugs, herbal products or vitamin supplements help prevent cognitive decline in healthy older adults.
The review, conducted at St. Michael's Hospital, found some evidence that mental exercises, such as computerized memory training programs, might help.
"This review provides some evidence to help clinicians and their patients address what strategies might prevent cognitive decline," said Dr. Raza Naqvi, a University of Toronto resident and lead author of the review.
Sex apparently is like income: People are generally happy when they keep pace with the Joneses and they're even happier if they get a bit more.
That's one finding of Tim Wadsworth, an associate professor of sociology at the University of Colorado Boulder, who recently published the results of a study of how sexual frequency corresponds with happiness.
As has been well documented with income, the happiness linked with having more sex can rise or fall depending on how individuals believe they measure up to their peers, Wadsworth found.
New research from the University of Copenhagen shows how public opinion on homosexuality has changed dramatically over the past 25 years. In his Ph.D. thesis, "Somewhere, over the Rainbow", Michael Nebeling Petersen analyzes Danish legislation, press coverage and films and concludes that homosexuality has become a symbol of liberal Danish values.
