How to get restful sleep and avoid stress during Sept. 11 anniversary

As the clock ticks down the hours to the start of ceremonies on the morning of September 11, 2008, commemorating the terror attacks of September 11, 2001, there is something we must all remember: it is okay to turn off the TV and not watch.

According to several studies done at three-month, six-months, and one-year following September 11, 2001, many people around the country had problems sleeping, especially in the first month following that tragic morning.

Later start time has positive impacts in schools

Delaying an adolescent’s school start time by one hour has a positive effect on his or her cognitive performance, according to a research abstract presented at Sleep 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).

The study, authored by Orna Tzischinsky, PhD, of Emek Yezreel College in Israel, focused on 47 eighth graders from two classes, who were divided into experimental and control groups for a two-week period. On week one, the experimental class began their school day one hour later than usual 8:30 a.m. start time. The control class, however, started right on time, as far as the school district was concerned: promptly at 7:30 a.m. On week two, both classes began at 7:30 a.m.

Sleep deprivation affects ability to make sense of what we see

Neuroscience researchers at the , located in Singapore, have shown for the first time what happens to the visual perceptions of healthy but sleep-deprived volunteers who fight to stay awake, like people who try to drive through the night.

The scientists found that even after sleep deprivation, people had periods of near-normal brain function in which they could finish tasks quickly. This normalcy mixed with periods of slow response and severe drops in visual processing and attention, according to their paper, published in the May 21, 2008 edition of .

Study takes a step toward better defining fatigue

In an effort to better define and ultimately address fatigue more effectively, a qualitative study from the has identified three primary themes loss of strength or energy, major effects of fatigue and associated sensations - among patients being treated with standard radiation therapy.

Presenting at the (), , , , an instructor in the Department of Symptom Research at , detailed commonalities of 21 patients who shared personal stories of dealing with cancer’s most distressing and common symptom.

"While fatigue is a well-recognized symptom of cancer and its treatment, the measurement of fatigue has been based on many different ideas and definitions. Few of these definitions have included patient input. We’re trying to define fatigue based on patient experience," said Williams.

"Once we’re able to determine the critical elements of fatigue, we’ll be better equipped to ask the right questions of patients to assess fatigue. Healthcare professionals — including nurses — will be in a much better position to intervene with patients to manage or prevent fatigue," Williams added.

The study included open-ended, audio-taped interviews with 21 patients, all who were receiving radiation therapy at M.D. Anderson. The patients were evenly divided with diagnoses of breast, prostate and head and neck cancer. Of the 21 patients who were interviewed during the fifth week of radiation therapy, 57 percent were women and the average patient was 54 years old.

In the study, patients reported a loss of strength or energy that included feelings of tiredness or weakness, which may progress to exhaustion, and lack of energy and stamina.

Because of the qualitative technique that Williams and her team used, their dialogues with patients revealed comments such as, "I don’t have a body part that is tired. My whole body is tired", "I just have a weak feeling … pretty well all over", and "Fatigue to me is just a feeling of no energy."

More than 85 percent of the patients in Williams’ study used the terms, "tiredness" and "lack of energy" to describe fatigue.

According to the researchers, these may be good terms for patients to use when speaking with health care providers about fatigue and terms that should alert the providers to patients experiencing it.

The team also reported that the effects of fatigue included a lack of motivation or inability to perform usual activities, decreased interest in social activities, and an overwhelming need to rest at times.

"Among the patients that we talked to, they often expressed an inability to do things that they could easily do before their treatment or before their diagnosis," said Williams. "They frequently reported that they didn’t want to be around others, that it took too much out of them to keep up a conversation or be cordial."

Williams and her team also pinpointed physical sensations associated with fatigue that included, "malaise, aching, feelings of heaviness or weight, slowness of movement, lack of appetite, and mental sensations of psychological distress and difficulty thinking or concentrating."

One patient described the physical sensations as "a feeling of heaviness," while another said, "I just felt myself dragged out, just tired, and it was distressing to me because that’s not my norm. I don’t like to feel like that."

"Defining the patient’s experience with a symptom is critical to assessing and managing that symptom," said Williams. "Assessing and managing symptoms, certainly fatigue, is a primary role of oncology nurses."

Collaborating with Williams on the study were Shannon Burkett, Ph.D.; Margaret H. White, B.A.; Ibrahima Gning, Ph.D.; and Charles Cleeland, Ph.D., and funding for the study was provided through a research grant from .

Apnea-related cognitive issues may be treated with green tea

Chemicals found in green tea may be able to stave off the cognitive deficits that occur with obstructive sleep apnea, according to a study published in the ’s second issue for May 2008 .

Researchers examined the effects green tea polyphenols, administered through drinking water, on rats who were intermittently deprived of oxygen during 12-hour "night" cycles, mimicking the intermittent hypoxia that humans with obstructive sleep apnea experience.
