The DRAGON score was 86 percent accurate in predicting the outcome three months after people had the stroke and received the drug within four-and-a-half hours after their first stroke symptoms.
“The DRAGON score is simple and fast to perform, it has no cost, and it consists solely of factors that are known when the patient is admitted to the hospital or soon after,” said study author Daniel Strbian, MD, PhD, of Helsinki University Central Hospital in Finland. “We found that we could determine the score in less than a minute. This can help the doctor, the patient, and the family to evaluate the situation, make choices and give the most relevant treatment with the greatest speed.”
Strbian said the score can help with the decision to try additional therapies when the likelihood is high that alteplase alone will not provide a good outcome.
The study involved 1,319 people with ischemic stroke with an average age of 69 who were treated with alteplase. Participants were given a score of zero to 10 based on their age, glucose level, time since stroke symptoms started, the severity of the stroke and other factors. The higher the score was, the more likely the person was to have a bad outcome three months later. A bad outcome was defined as being dead or being bedridden, incontinent and requiring constant nursing care and attention.
A total of 96 percent of those with scores of zero to two had a good outcome three months later. A good outcome was defined as being independent in daily activities. None of the people with DRAGON scores of eight to 10 had good outcomes three months later.
The score was also tested on a second group of 333 people at a hospital in Switzerland, with similar results.
The study was supported by Helsinki University Central Hospital, the Sigrid Juselius Foundation, the Finnish Medical Foundation and the Yrjö Jahnsson Foundation.

The American Academy of Neurology, an association of more than 25,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson’s disease and multiple sclerosis.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
