Researchers at the Sahlgrenska Academy at the University of Gothenburg and Chalmers University of Technology have now devised a new method that improves the accuracy of risk assessments.
Atrial fibrillation, or irregular heartbeat, is a very common heart rhythm disturbance that increases the risk of stroke and death. It is usually treated with warfarin, where the dose is calculated by measuring the coagulation of the blood. The dose is increased if coagulation is too quick, and decreased if it is too slow. Patients with unsatisfactory samples are tested more frequently, while satisfactory samples mean that the test interval can be extended.
New measurement method more reliable
In a study involving 20,000 patients in Sweden, Marcus Lind, postdoctoral researcher at the University of Gothenburg’s Sahlgrenska Academy and consultant at the NU group of hospitals, tested a new measurement method that assesses far more reliably who is at risk of serious complications and admission to hospital.
“Our method takes account of how blood viscosity goes up and down,” says Lind. “This meant that we could establish far more reliably which patients were at risk of a stroke, haemorrhaging or dying.”
Collaboration with Chalmers
The new method improves the chances of understanding which patients are at risk of complications, and is therefore an indicator for stepping up checks and probably reducing the risks.
“This is also important given the current debate about switching some patients who don’t settle on warfarin to a different kind of medication,” says Lind. “The new method pinpoints these patients more accurately.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
