Because there are more risks with having a total knee replacement in both legs at the same time than having a knee replacement in one leg, doctors in recent years have been selecting younger and healthier patients for the bilateral procedure. Now a new study by researchers at Hospital for Special Surgery has revealed that although patients are younger and healthier than those undergoing only one-sided surgery, they are becoming sicker and some complication rates have risen.

Research undertaken by the University of Southampton and its associates in Venice has revealed that the sea surface temperature (SST) in coastal regions is rising as much as ten times faster than the global average of 0.13 degrees per decade.
Researchers believe that this is partly as a result of a process known as the 'urban heat island effect'; where regions experiencing rapid industrial and urban expansion produce vast amounts of heat, making the area warmer than its surroundings.
Soft horns and a tinkling piano form the backbone of "Fifty Degrees North, Four Degrees West," a jazz number with two interesting twists: it has no composer and no actual musicians. Unless you count bacteria and other tiny microbes, that is.
The song is the brainchild of Peter Larsen, a biologist at the U.S. Department of Energy's Argonne National Laboratory. Larsen, it turns out, has no musical training at all; his interests run less towards the blues and more towards blue-green algae.
Boston, MA – Previous research has shown that observation units in a hospital can be an efficient way to care for certain patients, but only about one-third of hospitals in the United States have such units. Now, researchers at Brigham and Women's Hospital (BWH) estimate that maximizing the potential of an observation unit in a hospital could result in $4.6 million in savings annually for the hospital and $3.1 billion in overall savings for the health care system in the United States.
BLOOMINGTON, Ind. -- A new research study led by an Indiana University professor has found that social bullying is just as prevalent in children's television as depictions of physical aggression.
The study, "Mean on the Screen: Social Aggression in Programs Popular With Children," which appears in the Journal of Communication, found that 92 percent of the top 50 program for children between the ages of two and 11 showed characters involved in social aggression.
On average, there were 14 different incidents of social aggression per hour - or once every four minutes.
A new study found that patients with gout who consumed cherries over a two-day period showed a 35% lower risk of gout attacks compared to those who did not eat the fruit. Findings from this case-crossover study published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also suggest that risk of gout flares was 75% lower when cherry intake was combined with the uric-acid reducing drug, allopurinol, than in periods without exposure to cherries or treatment.
Boston, MA—Over 20 million people in the United States take beta-blockers, a medication commonly prescribed for cardiovascular issues, anxiety, hypertension and more. Many of these same people also have trouble sleeping, a side effect possibly related to the fact that these medications suppress night-time melatonin production. Researchers at Brigham and Women's Hospital (BWH) have found that melatonin supplementation significantly improved sleep in hypertensive patients taking beta-blockers.
Improved treatment options, a multi-pronged treatment model, and federal funding from the Ryan White Program have helped an inner city Baltimore clinic improve outcomes for HIV patients across all groups, including those most often hardest hit by the disease. Published in Clinical Infectious Diseases, the results from the 15-year analysis of patients at a clinic serving a primarily poor, African-American patient population with high rates of injection drug use demonstrate what state-of-the-art HIV care can achieve, given appropriate support.
Gout is one of the most common forms of inflammatory arthritis, affecting nearly 4% of adult Americans. Newly approved guidelines that educate patients in effective methods to prevent gout attacks and provide physicians with recommended therapies for long-term management of this painful disease are published in Arthritis Care & Research, a peer-reviewed journal of the American College of Rheumatology (ACR).

The benefits and cost effectiveness of helicopter transport for severely injured patients is of continued debate. New research published in BioMed Central's open access journal Critical Care shows that for severe blunt trauma, patients transported by helicopter had a lower risk of death, compared to those transported by road.
WASHINGTON, D.C. —Nurses and other hospital workers, especially those who work long hours or the night shift, often report trying to juggle the demands of the job and family obligations. A study out today by The George Washington University School of Public Health and Health Services (SPHHS) suggests that the higher the work-family conflict the greater the risk that health care workers will suffer from neck and other types of musculoskeletal pain.
SALT LAKE CITY, Sept. 27, 2012 – Mostly isolated from outsiders until the 1950s, Papua New Guinea's Enga tribes fought with bows and arrows until 1990, when their young people and mercenary "Rambos" began using shotguns and semiautomatic rifles, igniting 20 years of warfare that killed 4,816 people.
A study published in Science magazine contains new population assessments for thousands of fisheries around the globe, providing insight on the health of data-poor fisheries that account for more than 80 percent of the world's catch. The research confirms suspicions that these fisheries are in decline, but it also highlights hope for the future: most of these fisheries have not yet collapsed. If we act quickly to prevent overfishing and allow depleted stocks to recover to sustainable levels, they could provide more seafood over the long-term.
Santa Barbara – A study published in Science magazine and co-authored by Bren School Sustainable Fisheries Group (SFG) researchers and their colleagues confirms suspicions that thousands of "data-poor" fisheries, representing some 80 percent of the world's fisheries, are in decline but could recover with proper management.
