Defibrillators save many
A total of 1,115 people suffered cardiac arrest at Sahlgrenska University Hospital between 1994 and 2002, of whom 37% survived, and 86% of those were still alive a year later. For patients who could be treated with a defibrillator, the chances of surviving sudden cardiac arrest were three times higher inside hospital than outside hospital.
Longer time to treatment outside hospitalFor those who could not be treated with a defibrillator, survival was seven times higher among those in hospital. The difference is partly because it takes much longer to start defibrillation outside hospital.
“Other factors also play a role, though,” says Dr Fredriksson. “For example, most patients in hospital have a type of cardiac arrest that can be treated with a defibrillator, and the quality of CPR is better in hospital where victims can quickly be given highly advanced care.”
More victims outside hospital now surviveThe number of people surviving cardiac arrest outside hospital has nevertheless increased over the past decade.
“This is probably due to several factors, including the introduction of mechanical chest compression, but CPR by bystanders is also becoming more common, and follow-up care in hospital has improved.”9% fully survive

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...
