A study published today in the journal Critical Care shows that the main risk factors for death in the intensive care unit are central nervous system failure and cardiovascular failure, and the most frequent cause of death is multiple organ failure. In the hospital, once patients have been discharged from the intensive care unit, the main causes of death are malignant tumours and exacerbation of cardiovascular disease.
Viktoria Mayr and colleagues from Innsbruck Medical University collaborated with colleagues from other institutions in Austria to analyse the cause of death in 3700 patients admitted to intensive care units (ICU's). They analysed the causes of death in the ICU, in the hospital after discharge from the ICU, and one year after admission to the ICU.
Mayr et al.'s results show that 47% of patients who died in the ICU died of multiple organ dysfunction. Acute and chronic multiple organ dysfunction were much more common causes of death in the ICU than single organ failure. In addition, patients with central nervous system failure had a 16.07% increased risk of dying while in the ICU and patients with cardiovascular failure had an almost 12% risk of dying – these were the main risk factors for death while in the ICU. Mayr et al.'s results also show that malignant tumour disease caused over a third of hospital deaths in patients who had been discharged from the ICU, and one year after admission to the ICU. Exacerbation of chronic cardiovascular disease caused 19.4% of deaths after discharge from the ICU and it is the second most frequent cause of death both after discharge from the ICU and one year after admission to the ICU.

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...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
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...
