Potential Medical Applications For Interactive Data Eyeglasses
For car designers, secret agents in the movies and jet fighter pilots, data eyeglasses - also called head-mounted displays, or HMDs for short - are everyday objects. They transport the wearer into virtual worlds or provide the user with data from the real environment. At present these devices can only display information. "We want to make the eyeglasses bidirectional and interactive so that new areas of application can be opened up," says Dr. Michael Scholles, business unit manager at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden. A group of scientists at IPMS is working on a device which incorporates eye tracking - users can influence the content presented by moving their eyes or fixing on certain points in the image. Without having to use any other devices to enter instructions, the wearer can display new content, scroll through the menu or shift picture elements. Scholles believes that the bidirectional data eyeglasses will yield advantages wherever people need to consult additional information but do not have their hands free to operate a keyboard or mouse. The Dresden-based researchers have integrated their system"s eye tracker and image reproduction on a CMOS chip. This makes the HMDs small, light, easy to manufacture and inexpensive.

Family Physician Survey In Mainz: Patients With Depression Frequently Suffer From Medically Unexplained Pain
Pain symptoms that cannot be attributed, or at least not fully attributed, to an organic origin are more frequently and more severely experienced by patients with depression than by those without. "It is the case that women are much more frequently affected by depression and also by so-called somatoform pain disorder than men," explains Dirk Frieser, psychologist at the Institute of Psychology at Johannes Gutenberg University Mainz. For the purposes of his doctoral dissertation, Frieser and fellow psychologist Stephanie Kç¶rber questioned 308 patients attending two practices of general practitioners in Mainz. Patients were asked about their state of health and their pain symptoms, but also about their anxieties with regard to illness, how they react when ill, what social support they receive, and what psychological stress they experience, together with many other aspects. Subsequently, the pain symptoms reported by the patients were evaluated by their doctors.

Measurement Affects Racial Variations In Excessive Daytime Sleepiness

According to a research abstrac presented on Monday, June 8, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, white Americans are more likely to report experiencing excessive daytime sleepiness (EDS) more days per month than Asians, African Americans and Hispanics, but African Americans experience more severe EDS. Results indicate that of all racial groups in the study, white participants were most likely to report feeling excessively sleepy for more than five days a month. Of the total sample, 18.4 percent of white Americans reported EDS, as compared to 12.1 percent of Chinese, 14.3 percent of African Americans and 16.8 percent of Hispanics. The study also found that according to the Epworth Sleepiness Scale (ESS), a questionnaire used to measure the frequency of dozing off during the daytime, African Americans experienced higher rates of EDS than other racial groups. Of the total study, 13 percent of African Americans, 7.9 percent of whites, 7.7 percent of Chinese and 9.3 percent of Hispanics experience daytime sleepiness. According to lead author of the study Kelly Glaze Baron, PhD, postdoctoral fellow, at the Feinberg School of Medicine at Northwestern University in Chicago, Ill., the largest factor that explained higher EDS in African Americans was differences in physical health, including being more likely to be overweight and having higher rates of chronic diseases such as diabetes and high blood pressure. African Americans also reported to sleeping for less hours than other racial groups, which also contributes to higher rates of sleepiness. These results have public health implications. "If African Americans are less likely to report feeling overly sleepy but more likely to have pathological sleepiness, they may be less likely to get treatment for sleep disorders," said Baron. The study included data from 5,173 men and women with an average age of 66.4 years. Of the total sample, 40.7 percent of participants were white, 11.3 percent were Chinese, 26.2 percent were African American and 21.3 percent were Hispanic. Demographic information, health behavior (exercise and smoking), physical health and medications, sleep (self reported sleep time, diagnosis with sleep disturbance symptoms), depression, social support and chronic burden were collected. EDS was measured through self report of frequency (more than five days per month) and the ESS. Authors of the study claim that feeling overly sleepy takes into account attitudes, values and comparisons to family and friends. Findings of this study indicate that dozing off during the daytime has a stronger relationship to current health status.
