BOSTON – Patients with Alzheimer's disease who suffered episodes of delirium while hospitalized had a sharply increased rate of mental decline for up to five years after being hospitalized compared to those who did not have any such episodes, according to a study by researchers at The Institute for Aging Research at Hebrew SeniorLife, an affiliate of Harvard Medical School.

ROCHESTER, Minn. -- Each year, hundreds of thousands of X-rays are performed across the country to help detect and treat common cardiovascular conditions such as coronary artery disease, valve disease and other heart problems. However, concern is growing within the medical community about the potential risks of radiation exposure from this imaging technology. Now, researchers at Mayo Clinic have been able to dramatically cut the amount of radiation that patients and medical personnel are exposed to during invasive cardiovascular procedures.
A new statistical model predicts that by 2100 the number of people older than 85 worldwide will increase more than previously estimated, and there will be fewer working-age adults to support them than previously expected.
The findings, reported by researchers at the University of Washington and the United Nations, suggest an even greater decrease in the coming decades in support for social security programs for elderly adults.
New research from Psychological Science explores factors operating in political attitudes that could explain why political ideology and prejudice are often linked.
While most studies have sought (and therefore found) that political conservatism is linked to prejudice toward various stereotyped groups, it is also established that all people select and interpret evidence consistent with their own preexisting attitudes and ideologies - so if it happens that a whole lot more social scientists are liberal or progressive, they find more flaws in libertarians and conservatives.
Films made of semiconductor nanocrystals — tiny crystals measuring just a few billionths of a meter across — are seen as a promising new material for a wide range of applications. Nanocrystals could be used in electronic or photonic circuits, detectors for biomolecules, or the glowing pixels on high-resolution display screens. They also hold promise for more efficient solar cells.
The number of new cases of heart failure in Ontario decreased 33% over a decade, suggesting preventive efforts may be working. However, mortality rates remain high for people with the disease, states a study published in CMAJ (Canadian Medical Association Journal).
DENVER — New research indicates that urban American Indian youth who follow American Indian traditional spiritual beliefs are less likely to use drugs and alcohol. Arizona State University social scientists will present their findings at the 107th Annual Meeting of the American Sociological Association.
PHILADELPHIA, Aug. 20, 2012 — A gallon of regular gasoline cost 31 cents, a first-class postage stamp 4 cents and an office visit to the doctor's office $5. John F. Kennedy was president. Lawrence of Arabia won the Academy Award for Best Picture. A new band called The Rolling Stones got lots of attention.
A new study from Indiana University suggests there may be benefits to the controversial activities of "pro-ana" bloggers, the online community for people with eating disorders.
Most of the 33 bloggers from seven countries interviewed for the study, which has just been published in the journal Health Communication, said their writing activities provide a way to express themselves without judgment, which the authors believe can be crucial to their treatment.
DENVER — A new study led by the University of Cincinnati examines stereotypes of immigrants from four global regions and measures opinions of the impact of immigration on U.S. society. The researchers say their findings provide the most solid evidence yet that perceptions of the characteristics of Latin American immigrants in particular are strongly linked to beliefs about the impact of immigration, especially on unemployment, schools, and crime. The research will be presented at the 107th Annual Meeting of the American Sociological Association.
DENVER — Many refugees to the U.S. travel thousands of miles to a safe harbor, but once here find that adjusting to linguistic and cultural differences is an equally daunting task, according to new research to be presented by two University of Dayton sociologists at the 107th Annual Meeting of the American Sociological Association.
DENVER — American megachurches use stagecraft, sensory pageantry, charismatic leadership and an upbeat, unchallenging vision of Christianity to provide their congregants with a powerful emotional religious experience, according to research from the University of Washington.
Married couples who undergo long-term separations appear to be those who can't afford to divorce, a new analysis of survey results suggests. They found that about 80 percent of all respondents who went through a marital separation ultimately divorced, most within three years.
About five percent attempted to reconcile. But 15 percent of separations didn't lead to divorce or reconciliation within 10 years. Couples in these long-term separations tended to be racial and ethnic minorities, have low family income and education, and have young children.
A study by Indiana University sociologist Jessica McCrory Calarco found that working-class and middle-class parents often take very deliberate -- but different -- approaches to helping their children with their school experiences.
Working-class parents, she found, coached their children on how to avoid problems, often through finding a solution on their own and by being polite and deferential to authority figures. Middle-class parents, on the other hand, were more likely to encourage their kids to ask questions or ask for help.
DENVER — New research examining relationships and the use of alcohol finds that while a long-term marriage appears to curb men's drinking, it's associated with a slightly higher level of alcohol use among women. The study, led by the University of Cincinnati (UC), will be presented at the 107th Annual Meeting of the American Sociological Association.
