Coronary artery surgery performed "off-pump", i.e., keeping the heart beating and not using the cardiopulmonary bypass machine, has similar outcomes after one year, and costs less, when compared to conventional coronary artery bypass grafting (CABG) using cardiopulmonary bypass, according to a study in the April 21 issue of The Journal of the American Medical Association (JAMA).
To try to avoid some of the complications attributable to cardiopulmonary bypass, U.S. surgeons performed approximately 21 percent of coronary artery bypass operations off-pump in 2002, according to background information in the article. In off-pump operations, the heart is kept beating, and with the help of a device, the beating heart is stabilized while the surgeon places the bypass grafts around the blocked arteries. During a conventional CABG surgery, a heart-lung machine allows the heart to stop and pumps blood throughout the body, and keeps the body stabilized. Concerns remains about the technical difficulty of off-pump coronary artery bypass (OPCAB), including the possibility of imprecise grafting and incomplete revascularization compromising patient outcomes, and long-term graft patency (keeping the graft open).
John D. Puskas, M.D., M.Sc., of the Emory University School of Medicine and Emory Center for Outcomes Research, Atlanta, and colleagues conducted the Surgical Management of Arterial Revascularization Therapies (SMART) trial, designed to compare graft patency, clinical outcomes, health-related quality of life, and costs in unselected patients referred for elective, isolated CABG surgery and randomized to OPCAB or CABG with cardiopulmonary bypass. The study included 197 patients who had follow-up at 30 days; 185 of those had follow-up at 1 year. The study was conducted between March 10, 2000, and August 20, 2001, at a U.S. academic center.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
