In a study in the April 15th issue of Biological Psychiatry, researchers have found that an inexpensive, widely available drug was successful in reducing symptoms in chronic PTSD patients.
In a placebo-controlled, blinded study of 40 veterans of the Vietnam War (32 subjects), World War II (2), the Korean War (3), the Panama invasion (1) and the first Gulf War (2), prazosin was significantly more effective than placebo in reducing trauma nightmares, improving sleep quality and improving the general clinical condition of the treated patients.
Subjects were assessed using three primary outcome measures, the CAPS “recurrent distressing dreams” item, the Pittsburgh Sleep Quality Index (PSQI) and the Clinical Global Impression of Change (CGIC). The CAPS “recurrent distressing dreams” item measures frequency and intensity of trauma-related distressing dreams. The PSQI is a self-report scale assessing sleep quality and sleep disturbance. The CGIC is an investigator rated assessment of change in global clinical status, which was defined in this study as sense of well-being and ability to function in daily activities.
Improvements in all three measures were observed, with 71% of the subjects receiving prazosin having “moderately or markedly improved” CGIC scores at the end of the study, compared to 12% of those receiving placebo.
Writing in the article, Murray A. Raskind, MD, states, “These results support the therapeutic use of prazosin for PTSD in combat veterans who present with trauma nightmares and sleep disturbance. Clinical experience suggests that prazosin also is beneficial for PTSD trauma nightmares and sleep disturbance in young civilian trauma victims, young veterans of the current conflict in Iraq and Afghanistan and in elderly World War II and Korean War combat veterans and Holocaust survivors.”

Raskind, Elaine R. Peskind, David J. Hoff, Kimberly L. Hart, Hollie A. Holmes, Daniel Warren, Jane Shofer, James O’Connell, Fletcher Taylor, Christopher Gross, Kirsten Rohde, and Miles E. McFall.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
