David Callans, MD, a professor of cardiovascular medicine at the University of Pennsylvania School of Medicine, will be available to comment on the New England Journal of Medicine study on the use of automated external defibrillators (AEDs) for sudden cardiac arrests that occur in the home. Callans, author of the journal editorial that accompanies the new study, serves as associate director of electrophysiology for the Penn Health System, and has extensive experience in studying ventricular arrhythmias.
The news that the devices, which deliver shocks to restore the heart to its normal rhythm, don’t improve survival for those who have cardiac arrests at home may seem counterintuitive, he says.
“Arguments in favor of access to AEDs have an emotional quality that is not completely captured by success rates or cost efficacy of therapy,” Callans says. “But in light of the study findings and the high cost of the devices, future efforts should turn toward education, modification of risk factors and other methods for primary prevention of heart disease.”
Of the 170,000 sudden cardiac arrests that occur outside hospitals in the United States each year, about 80 percent take place in the home – with just two percent of victims surviving. The Home Automated External Defibrillator Trial (HAT), led by researchers at the Seattle Institute for Cardiac Research and the Duke University Clinical Research Institute, examined whether placement of automatic external defibrillators in the homes of patients at risk of sudden cardiac arrest would improve these survival odds.
HAT study researchers found that AEDs, which are increasingly being used in public places like airports and sports arenas, did not significantly improve a patient’s chances for survival during cardiac arrests in the home, compared with conventional resuscitation methods like CPR. Results of the study, to be presented April 1 at the American College of Cardiology Annual Scientific Session in Chicago, will be published in the April 24, 2008 print edition of the journal.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
