Pretreating a vein graft with edifoligide prior to coronary bypass graft surgery does not lower the rate of graft failure

Coronary artery bypass graft (CABG) surgery is one of the most common surgical procedures performed in the United States, according to background information in the article. In appropriately selected patients, CABG surgery results in improved survival, relief of angina, and improved quality of life. Despite frequent use of artery grafts, vein grafts remain the most frequently used conduit.

New digital angiography flat panel system reduces the radiation dose to patients undergoing interventional treatment for liver cancer

The study compared the radiation dose to patient's skin during transcatheter arterial embolization, a procedure that blocks the flow of a blood to a tumor. Doses were assessed for 12 patients using a new angiography unit with a digital flat-panel system and 12 using a conventional unit for angiographic imaging.

Separate studies produce conflicting results on race and gender disparities in U.S. health system

Two newly released studies in the U.S. have to some extent come to conflicting results. According to one study, by researchers at Emory University, attempts over the last decade to address race and gender disparities in the treatment of U.S. patients hospitalized for heart attacks, still in some respects raise cause for concern.

Treatment options for skull base tumors

It is estimated that in 2000, more than 359,000 persons were living with a diagnosis of a primary brain tumor in the United States. In 2005, it is estimated that nearly 12,800 deaths will be associated with malignant tumors of the brain and other parts of the central nervous system. Brain tumors are the leading cause of cancer-related deaths in children age 19 and younger.
