Race and sex disparities in heart attack care, survival not improving
Differences based on race and sex in treatment patterns for hospitalized American heart attack patients have remained unchanged over an eight-year period, despite improvements in quality of heart attack care during this time, Emory and Yale School of Medicine researchers write in the August 18 issue of New England Journal of Medicine.

Ways to avoid hazards of heart bypass under study
The heart-lung bypass machine that stills the heart while surgeons bypass an adult's clogged arteries or repair a baby's malformed heart can also trigger a potentially deadly inflammatory response.

Improving the potential of cancer vaccines
A special stretch of genetic material may turn off the immune suppression that stymies attempts to fight cancer with a vaccine, said researchers at Baylor College of Medicine (BCM) at Houston.

Researchers seek to discover what really happens when a virus enters the body
Does the immune system respond to viruses because they are foreign or when they cause harm?

New defibrillator signals doctor of patient's irregular heartbeat or device malfunction
In a major advance for heart patients, Loyola University Health System is the first hospital in the U.S. to implant into a patient a new FDA-approved defibrillator which automatically signals the doctor via wireless satellite transmission if the patient's heart beats abnormally or if the device malfunctions, e.g., battery failure.

K-State eye researchers focus on stopping spread of damaged eye cells
A team of four eye researchers at Kansas State University is examining how cells communicate.
