The pulmonary artery catheter (PAC), a device that measures pressures and flows in the heart, is frequently used to diagnose, monitor, and guide treatment of congestive heart failure and other conditions. However, use of the PAC has been controversial with varying opinions as to its risk and benefits. New findings from a multi-center study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health show that the PAC did not significantly increase or decrease deaths or the number of days hospitalized in patients with severe heart failure.
The results of the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) Trial are being presented today in the late-breaking clinical trials section of the American Heart Association’s Scientific Sessions 2004. “Heart failure affects about 5 million Americans and the numbers are growing. So it is important to find out the best way to diagnose and treat this serious condition. The ESCAPE study lays to rest concerns that use of a pulmonary artery catheter in patients with advanced heart failure is associated with increased death and hospitalization. At the same time, the study suggests that PAC should not be used routinely to guide therapy. This is an invasive procedure with potentially serious complications and, without a definite survival benefit, its use should be carefully evaluated,” said NHLBI Acting Director Barbara Alving, M.D.
About 4 percent of the patients undergoing pulmonary artery catheterization experienced complications, including cardiac arrest and infection but there were no PAC-related deaths. Patients in both groups studied – those who received a PAC and those whose therapy was guided by clinical assessment – spent about 8 days in the hospital.

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...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
