Study demonstrates feasibility of a revolutionary, minimally invasive approach to introducing an electrical lead to stimulate the heart

Correcting the timing of heart contractions through cardiac resynchronization therapy can be a lifesaver for people with advanced heart failure. But the procedure, as it is done today, fails in about 15 percent of patients.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

New treatment for the pediatric eye cancer retinoblastoma

Investigators at St. Jude Children's Research Hospital have demonstrated in laboratory studies a new treatment for the pediatric eye cancer retinoblastoma that appears to be more effective than the current standard therapy, and more likely to prevent the recurrence of this cancer. A report on their work appears in the October 15 issue of Clinical Cancer Research.

Long-term smoking linked to diminished mental proficiency

The association between long-term smoking and diminished mental proficiency in 172 alcoholic and non-alcoholic men was a surprising finding from a study that set out to examine alcoholism's long-term effect on the brain and thinking skills.

Rates for new cases of kidney failure have stabilized

After 20 years of annual increases from 5 to 10 percent, rates for new cases of kidney failure have stabilized, according to new research from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). At the same time, dramatic racial disparities persist.

Eyes reveal risk of stroke

Looking into our eyes may help doctors predict who is at risk for stroke. A new study found that people with changes in the small blood vessels in their eyes are more likely to later suffer a stroke than people without these signs.

Association between long-term smoking and diminished mental proficiency

Smokers often say that smoking a cigarette helps them concentrate and feel more alert. But years of tobacco use may have the opposite effect, dimming the speed and accuracy of a person’s thinking ability and bringing down their IQ, according to a new study led by University of Michigan researchers.

New data demonstrates how CA4P has anti-tumor and anti-angiogenic activity

Anti-angiogenic agents have been successful in the clinic for blocking the growth of solid tumors. However, these agents used in combination with chemotherapy have improved the survival of patients with cancers by only several months.

PACs should not be used routinely in patients in intensive care units with severe heart failure

The use of a pulmonary artery catheter (PAC) -- a device used for more than 30 years to assess cardiovascular health and to help guide the treatment of critically ill patients -- does not appear to improve outcomes nor confer added risks to patients.
