Patients who feel better live longer, say Mayo Clinic researchers, in study results. The team found that baseline quality of life was a strong predictor of survival.

Researchers have shown that an electric shock ranging from 120 to 52,000 volts can cause neurologic and neuropsychological symptoms in humans. Following an electrical injury, some patients may show various emotional and behavioral aftereffects, such as memory loss and symptoms of depression.

As men age, their risk of developing prostate cancer increases. Aging Vietnam veterans are giving researchers new opportunities to solidify the connection between in-country exposure to Agent Orange and subsequent prostate cancer development.

Researchers have discovered a drug combination that kills leukemia cells by shutting down their energy source and hastening cell starvation.

Acute kidney injury, a common complication of cardiac surgery during hospitalization, is linked to increased and prolonged risk of death in heart attack patients who have been discharged from the hospital, according to a study published in Archives of Internal Medicine.

A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help researchers more accurately determine a woman's risk for developing breast cancer and provide a new approach for treatment.

As unlikely as it sounds, scientists have shown that there is a link between prostate cancer and a higher risk of bone fracture. Men with prostate cancer face a 50% higher risk of fracture, which increases to nearly doubled risk if they are receiving treatment.

In the largest study of its kind to evaluate commonly used HIV drugs, researchers confirmed that one of the most frequently prescribed triple drug combinations for initial HIV infection is indeed the most effective at suppressing HIV. The study also found that a two-drug regimen performed comparably to the triple-drug regimens.

Obesity, unhealthy lifestyles and lower social economic status have been linked to more complex urinary problems in an American survey of 5,506 men and women. 58 percent were female, 32 percent were white, 32 percent were black and 34 percent were Hispanic.

In a discovery that could one day lead to an understanding of how to regenerate damaged heart tissue, researchers have found that parent cells involved in embryonic development of the epicardium -- the cell layer surrounding the outside of the heart -- give rise to three important types of cells with potential for cardiac repair.
