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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
