Calypso Medical Study Shows Potential For Improving Radiotherapy Treatment Accuracy Of Deadly Pancreatic Tumors
Calypso Medical Technologies, Inc., announced the publication of data from a clinician sponsored investigational study conducted at the University of Pennsylvania, demonstrating the utility of the Calypso® System in tracking tumor movement in the pancreas. The data will be presented at the 51st Annual Meeting of the American Association of Physicists in Medicine (AAPM), July 26-30, at the Anaheim Convention Center. "In areas of the body, such as the pancreas, that are susceptible to respiratory motion it can prove difficult to handle the spectrum of motion that can arise," said James Metz, M.D., Clinical Director, Department of Radiation Oncology, The University of Pennsylvania Health System.

'Life Force' Linked To Body's Ability To Withstand Stress
Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well, according to a study published in the July issue of the journal Brain, Behavior and Immunity. Especially in aging women, low levels of the personality trait extraversion may signal that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years.

A Bidirectional Relationship Between Chronic Stress And Sleep Problems shown by study

According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, people with chronic stress report shorter sleep duration, worse sleep quality, and more daytime functioning impairments. Conversely, daytime functioning impairments and shorter sleep duration demonstrated a predictive relationship with habitual stress complaints. Results indicate that poor sleep may be a potential cause of stress; individuals who report more fatigue and less total sleep are more likely to report more stress. According to principal investigator Eric Powell, PhD, director of research at the Research Center at Clayton Sleep Institute in St. Louis, Mo., factors that were the best predictors of high stress were daytime functioning and typical amount of sleep. "The simplest, and likely best advice for individuals with high stress and poor sleep is to look at some of the lifestyle choices they are making and ensuring sufficient sleep is at the core of those choices," said Powell. The study involved data from 544 patients at the Midwestern metropolitan sleep center who received diagnostic polysomnograms. Participants ranged in age from 18 to 79 years, were not shift workers, and had no prior sleep disorder diagnosis. Subjects completed a brief estimate of their state and trait stress, and sleepiness was assessed subjectively; individuals were divided into low and high-trait stress groups.
