If you have stable cardiovascular disease, it is more than likely that you can safely engage in sexual activity, according to an American Heart Association scientific statement.

The statement, published online in Circulation: Journal of the American Heart Association, contains recommendations by experts from various fields, including heart disease, exercise physiology and sexual counseling.

A simple program involving color-coded food labeling and adjusting the way food items are positioned in display cases was successful in encouraging more healthful food choices in a large hospital cafeteria. The report from Massachusetts General Hospital (MGH) researchers will appear in the March American Journal of Public Health and has received early online release.

TORONTO, Ont. Jan. 19, 2012—Up to 30 per cent of patients hospitalized after a stroke develop delirium, according to a new study from St. Michael's Hospital.

Researchers found patients who experience delirium after stroke are five times more likely to die, and are more likely to be discharged to a long-term care facility, nursing home or have a longer stay in hospital.

RICHMOND, Va. – (Jan. 19, 2012) – More than 20 percent of U.S. adults receive periodic health examinations (PHE) each year, yet new research shows that patients who have an annual routine visit to their doctor may not receive recommended preventive screening tests and counseling services that could benefit their health.

More than 250,000 hip fractures occur every year in the U.S., often resulting in hospitalization, surgery, nursing-home admission, long-term disability, and/or extended periods of rehabilitation. Independent existing medical conditions (otherwise known as comorbidities) significantly increase the treatment cost and length of hospitalization for older adults who have sustained a hip fracture, according to a new study recently published in the Journal of Bone and Joint Surgery.

States reduced per-student funding for major public research universities by a fifth during the past decade, while foreign competitors invested heavily to challenge the United States' once dominant global position in science, innovation, and higher education, according to new data publicly released today by the National Science Board (NSB).

A researcher at the University of Barcelona has examined the construction of surface transportation infrastructure in Spain from 1720 to 2010. The economist and author of the study, Germà Bel explains how both the construction of train lines and state highways in Spain since the 18th century has been based radially around Madrid as the political capital and not on the commercial activity of routes.

An estimated 1.6 million Americans suffer moderate to severe leakage through their tricuspid valves, which are complex structures that allow blood to flow from the heart's upper right chamber to the ventricle. If left untreated, severe leakage can affect an individual's quality of life and can even lead to death.

A new study, published in the Journal of Marriage and Family reveals that married couples experience few advantages for psychological well-being, health, or social ties compared to unmarried couples who live together. While both marriage and cohabitation provide benefits over being single, these reduce over time following a honeymoon period.

NEWPORT, Ore. – A new study suggests that the impact of predation on juvenile Steller sea lions in the Gulf of Alaska has been significantly underestimated, creating a "productivity pit" from which their population will have difficulty recovering without a reduction of predators.

Scientists using "life history transmitters" to study Steller sea lions found evidence of age-structured predation by orcas (killer whales) and other large predators in Alaska's Prince William Sound and adjacent areas, which may change with the population density of the sea lions.

(SACRAMENTO, Calif.) -- UC Davis Health System dermatologists, using videoconferencing technology known as teledemedicine, have determined that live interactive consultations can improve clinical outcomes for patients because they usually involve beneficial changes in medical diagnosis and disease management that otherwise might not occur.

ANN ARBOR, Mich.—A program built around the concept that kids can and want to reduce violence and improve their neighborhoods led to lower crime rates, better upkeep on homes and more students who said they learned to resolve conflicts without violence.

Pain management is a high priority for patients with rheumatoid arthritis, so three researchers in Australia analysed existing study data to see whether two different classes of drugs can help. When looking at muscle relaxants, they discovered that neither the benzodiazepine agents, diazepam and triazolam, nor the non- benzodiazepine agent, zopiclone, reduce pain when taken for one to 14 days. However, even this short use was associated for both agents with drowsiness and dizziness.

Since mephedrone was made illegal in the UK in 2010, the street price of the drug has risen while the quality has degraded, which in turn may have reduced use of the drug. New research published online today reveals that young people who continued to use mephedrone after it became illegal would switch to a new legal high if it were pure and rated highly by their friends or on the Internet. They would be less deterred by a lack of scientific research on the new drug.
