Injury and hazards in home health care nursing are a growing concern

October 5, 2009 -- Patients continue to enter home healthcare ''sicker and quicker," often with complex health problems that may require extensive nursing care. This increases the risk of needlestick injuries in home healthcare nurses. While very few studies have focused on the risks of home healthcare, it is the fastest growing healthcare sector in the U.S.

Drug-eluting stents better than bare-metal stents for heart attack patients

SAN FRANCISCO, CA -- SEPTEMBER 25, 2009 -- Late-breaking data from the landmark HORIZONS-AMI clinical trial, presented at the 21st annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, demonstrated that after two years, in heart attack patients, the use of a drug-eluting stent (paclitaxel) was safer and more effective than a bare-metal stent; and that the administration

Pitt researchers net $5 million from NIH to explore better ways to grow cells

PITTSBURGH -- Regenerative medicine researchers at the University of Pittsburgh received two grants totaling more than $5 million from the National Institutes of Health (NIH) to explore new methods for cultivating replacement cells from existing tissues and organs.

North meets south? Glaciers move together in far-flung regions

Results of a new study add evidence that climate swings in the northern hemisphere over the past 12,000 years have been tightly linked to changes in the tropics.

Coronary imaging techniques helps to identify plaques likely to cause heart attacks

SAN FRANCISCO, CA -- SEPTEMBER 24, 2009 -- Late-breaking results from the PROSPECT clinical trial shed new light on the types of vulnerable plaque that are most likely to cause sudden, unexpected adverse cardiac events, and on the ability to identify them through imaging techniques before they occur.

Peruvian glacial retreats linked to European events of Little Ice Age

DURHAM, N.H. -- A new study that reports precise ages for glacial moraines in southern Peru links climate swings in the tropics to those of Europe and North America during the Little Ice Age approximately 150 to 350 years ago.

Researchers identify new brain pathway for regulating weight and bone mass

Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain, according to a recent study published in Cell by Yale School of Medicine researchers and colleagues at Columbia University.

SPIRIT IV trial shows everolimus stent sets new standard for event-free survival

SAN FRANCISCO, CA -- SEPTEMBER 23, 2009 -- Late-breaking data from SPIRIT IV, a large-scale multi-center study of nearly 4,000 patients in the U.S., shows that an everolimus-eluting stent demonstrated enhanced safety and efficacy in the treatment of de novo native coronary artery lesions when compared to a paclitaxel-eluting stent, and showed that "low late loss" may be achieved with drug-elu

Oxygen-saturated blood reduces levels of damaged heart tissue following a heart attack

NEW YORK -- SEPTEMBER 15, 2009 -- Results of a clinical trial published today in Circulation: Cardiovascular Interventions demonstrate that an infusion of blood that is "supersaturated" with oxygen (SS02) can reduce the amount of damaged heart muscle immediately following a life-threatening heart attack.

Two treatment innovations improve heart function after heart attack

Supersaturated oxygen (SSO2) administered during catheter-based treatments for heart attack can significantly reduce heart muscle damage, according to a new study reported in Circulation: Cardiovascular Interventions, a journal of the American Heart Association.

In another study from the same issue, a different group of researchers found that manually removing a blood clot provided greater

In study of low-income toddlers, spanking found to have negative effects

A new longitudinal study that looks at how low-income parents discipline their young children has found that spanking 1-year-olds leads to more aggressive behaviors and less sophisticated cognitive development in the next two years. Verbal punishment is not associated with such effects, especially when it is accompanied by emotional support from moms.

Genes may explain why children who live without dads have earlier sex

Previous research has found that children raised in homes without a biological father have sex earlier than children raised in traditional nuclear families. Now a new study that used a novel and complex design to investigate why this is so challenges a popular explanation of the reasons.

Study identifies which children do not need CT scans after head trauma

A substantial percentage of children who get CT scans after apparently minor head trauma do not need them, and as a result are put at increased risk of cancer due to radiation exposure.

Mandatory alcohol testing for truck and bus drivers reduces alcohol involvement in fatal crashes

September 10, 2009 -- Mandatory alcohol testing programs for truck and bus drivers have contributed to a significant reduction in alcohol involvement in fatal crashes, according to a new study by researchers at the Mailman School of Public Health and the Johns Hopkins Bloomberg School of Public Health.

New type of adult stem cells found in the prostate may be involved in prostate cancer development

NEW YORK -- A new type of stem cell discovered in the prostate of adult mice can be a source of prostate cancer, according to a new study by researchers at the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center and NewYork-Presbyterian Hospital.
