A scary unknown for many children, the prospect of surgery can cause intense preoperative anxiety. While some amount of stress is normal, what many parents do not know is that extreme anxiety before surgery can contribute to the occurrence of emergence delirium, a distressing incidence of acute behavioral changes experienced when "waking up" from anesthesia.
WHAT: Food prices rose by 5.5 percent in the past year and are expected to increase up to an additional 4 percent in 2009. Americans are seeking to get the most out of their dollar, and since together, dairy foods provide a unique package of nine essential nutrients, they are a nutritional bang for the buck.
Tampa, Fla. (July 1, 2009) – The frontiers of cell transplantation for cardiac repair are discussed in the current issue of Cell Transplantation (Vol. 18 No.3), now available on-line without charge at http://www.ingentaconnect.com/content/cog/ct.
Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications because the device holds promise as a stylus for sensing very small forces or as an interface for efficient transfer of individual light particles for quantum communications.
Rosemont, Ill. — People with ankle injuries who do not respond successfully to initial treatment may have a second chance at recovery, thanks to two new procedures developed to restore the injured area, according to a study published in the July 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS).
The study reviews emerging techniques that have proven successful in treating injuries to the talus, the small bone, which is located between the heel bone and the lower bones of the leg. The talus helps form the ankle joint.
Clinical pathways have been used in surgeries since the 1980s, but their nature and usefulness are still subjects of much debate, especially as procedures such as hip and knee joint replacement represent a significant cost to hospitals. Now authors publishing in the open access journal BMC Medicine have concluded that using clinical pathways can effectively improve the quality of the care provided to patients undergoing joint replacement.
Use of several older and newer biomarkers appears to offer minimal added benefit in the prediction of cardiovascular events compared to conventional risk factors such as high cholesterol and high blood pressure, according to a study in the July 1 issue of JAMA.
ANN ARBOR, Mich.---Researchers at the University of Michigan have devised a microscale tool to help them understand the mechanical behavior of biofilms, slimy colonies of bacteria involved in most human infectious diseases.
Most bacteria in nature take the form of biofilms. Bacteria are single-celled organisms, but they rarely live alone, said John Younger, associate chair for research in the Department of Emergency Medicine at the U-M Health System. Younger is a co-author of a paper about the research that will be the cover story of the July 7 edition of Langmuir.
It's a frequent scene in television crime dramas: Clever police technicians zoom in on a security camera video to read a license plate or capture the face of a hold-up artist. But in real life, enhancing this low-quality video to focus in on important clues hasn't been an easy task. Until now.
