A small study published today in the journal Critical Care, reveals that most Intensive Care Unit (ICU) patients who gave their informed consent to take part in a clinical trial remembered having participated in the trial ten days later. But two-thirds of the patients did not remember the purpose and risks of the trial, although they had been given information about them before the trial started.
Catherine Chenaud and colleagues from the University Hospital of Geneva, Switzerland, studied 44 ICU patients who had been selected for a clinical trial on inflammatory responses. The patients were given a 20-minute presentation about the study, its purpose and its risks and were given a leaflet to read, before agreeing to participate in the trial. They were then interviewed ten days later.
Chenaud et al.’ s results show that 35/44 patients remembered having taken part in the trial, but that only 20/44 patients remembered the purpose of the study and only 21/44 patients remembered the study risks. Furthermore, only 14/44 patients remembered both the purpose of the trial and its associated risks. The 14 patients who remembered all aspects of the trial did not differ from other patients, except that they had read the leaflet or had asked at least one question during the presentation, before signing the consent form.
The authors conclude that obtaining informed consent from patients should be a process which is revisited many times, rather than one event at the start of the trial, and that patients should be given information repeatedly during the course of a trial.

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...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...
