Risk Factors For Developing Complications From Sleep Apnea Surgery
Patients undergoing surgery to correct sleep apnea are more likely to have complications if their condition is severe, they have a high body mass index, they have other medical problems or they are undergoing certain other surgical procedures at the same time, according to a report in the October issue of Archives of Otolaryngology—Head & Neck Surgery, one of the JAMA/Archives journals.

Studying sleep deprivation's effect on decisions
Everyone needs sleep, but temporary periods with no sleep can be a reality of military operations. To get answers on sleep questions for the military as well as civilians, for nearly four years Dr. Sean Drummond, a Department of Defense-funded researcher, has studied the effects of sleep deprivation on the brain, namely in decision making, as well as how long it takes to recover from periods of no sleep.

New sleep gene discovery wakes up scientists
Proteins that regulate sleep and biological timing in the body work much differently than previously thought, meaning drug makers must change their approach to making drugs for sleep disorders and depression and other timing-related illnesses. The surprise finding is an about-face from previous research, said Daniel Forger, assistant professor of math at the University of Michigan. Forger and his collaborators from the University of Utah's Huntsman Cancer Institute have written a paper on the topic, which will appear on in the July 11 issue of the Proceedings of the National Academy of Science.

Diphenhydramine Does Not Improve Infant Sleep
An antihistamine often recommended to parents whose infants do not sleep through the night may not be effective in reducing nighttime awakenings or improving parents' happiness with their children's sleep, according to a report in the July issue of the Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. Between 20 and 46 percent of parents have reported that their infants have trouble sleeping, according to background information in the article. Some parents let their children cry for extended periods at night-this method, known as crying out, is popular but controversial among parents and health care professionals. Another commonly used method is to give children medications-such as antihistamines, normally used to treat allergies-to sedate them at bedtime. Diphenhydramine hydrochloride, sold as Benadryl, is often used by parents and recommended by physicians despite the fact that it has not been studied in children younger than age 2 years.

People sleep even less than they think
A study of the sleep characteristics of 669 middle-aged adults found that people sleep much less than they should, and even less than they think. Published in the July issue in the American Journal of Epidemiology, the study also found that blacks sleep less than whites, men sleep less than women, and the poor sleep less than the wealthy.

Computer models may reveal what makes human body clock tick
Scientists at the University of Edinburgh are using digital technology to develop an artificial body clock which can tell them more about the causes of sleeplessness. The computer-designed clock, which mimics the workings of key genes and proteins in the brain, can shed new light on the complex biological processes which influence our internal rhythms. The study is part of major Europe-wide investigation into sleep disturbance, which is a growing problem in the EU where one in every five employees now works shifts.

New fruit fly protein JET illuminates circadian response to light
Researchers at the University of Pennsylvania School of Medicine have identified a new protein required for the circadian response to light in fruit flies. The discovery of this protein – named JET – brings investigators one step closer to understanding the process by which the body's internal clock synchronizes to light. Understanding how light affects circadian (24-hour) rhythms will likely open doors to future treatments of jetlag.

Children with fetal alcohol spectrum disorders exhibit altered sleeping and eating patterns
Children with fetal alcohol spectrum disorders (FASD) suffer from a variety of behavioral alterations. For example, they may exhibit alterations in sleeping and eating patterns, which may indicate that their circadian systems – which control biological rhythms – have been affected by alcohol exposure during development. A rodent study in the May issue of Alcoholism: Clinical & Experimental Research confirms that alcohol exposure during a period equivalent to the third human trimester influences the ability to synchronize circadian rhythms to light cues.

Sleep Disorders and Sleep Deprivation: An Unmet Public Health Problem
It is estimated that 50 to 70 million Americans chronically suffer from a disorder of sleep and wakefulness, hindering daily functioning and adversely affecting health and longevity. The cumulative long-term effects of sleep loss and sleep disorders have been associated with a wide range of deleterious health consequences including an increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke.
Hundreds of billions of dollars a year are spent on direct medical costs associated with doctor visits, hospital services, prescriptions, and over-the-counter medications. Almost 20 percent of all serious car crash injuries in the general population are associated with driver sleepiness, independent of alcohol effects.
Despite such huge societal consequences and costs, the Institute of Medicine (IOM) finds that the cumulative effects of sleep loss and sleep disorders are "under- recognized" and "awareness among the general public and health care professionals is low given the magnitude of the burden”

Children who sleep less are three times more likely to be overweight
The less a child sleeps, the more likely he or she is to become overweight, according to researchers from Université Laval's Faculty of Medicine in an article published in the latest edition of the International Journal of Obesity. The risk of becoming overweight is 3.5 times higher in children who get less sleep than in those who sleep a lot, according to researchers Jean-Philippe Chaput, Marc Brunet, and Angelo Tremblay.

Studies by Brown, Lifespan scientists are at cutting edge of sleep research
A new poll of teenagers across the US finds that many of them are losing out on quality of life because of a lack of sleep. The results, announced today by the National Sleep Foundation (NSF), cite sleeping in class, lack of energy to exercise, feelings of depression, and driving while drowsy as only some of the consequences for insufficient sleep.

Association noted between sleep apnea and cardiovascular disease
In the current issue of the New England Journal of Medicine, two studies draw attention to the newly recognized association between sleep disorders and heart trouble. The relevance of these studies to patients with sleep apnea is discussed in an accompanying editorial by Virend Somers, M.D., Ph.D., a Mayo Clinic cardiologist. The first study, on the use of continuous positive airway pressure (CPAP) for patients with central sleep apnea and heart failure, was led by T. Douglas Bradley, M.D., of Toronto General Hospital. The other study on obstructive sleep apnea as a risk factor for stroke and death was led by H. Klar Yaggi, M.D., of Yale Center for Sleep Medicine.

Avoid jet lag by resetting body clock
A simple, at-home treatment -- a single light box and the over-the-counter drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones, according to new research being published in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism. This treatment can also help those with delayed sleep phase syndrome (DSPS), a persistent condition that results from a misalignment between a person's internal biological clock and the external social environment.

Clocking in Pillow Time without the Pillow
If you snooze, you lose those uncomely grayish-brown crescents below your eyes. If you don’t snooze, you lose a lot more. The body can’t fight off infection, the muscles can’t regenerate as quickly, the mind can’t learn new words, and the eyes can’t focus on the road. You also gain things: a bad mood and increased risk for diabetes, high blood pressure, and heart problems. Indeed, the effects of sleep deprivation can be so serious that some sleep scientists liken lifetime sleep debt to a heavy backpack: every sleep hour missed adds an extra pound to your pack until it weighs you down.

Genetic disease offers clues to SIDS, sleep apnea
Imagine raising a child who stops breathing when falling asleep – and has to be reminded to visit the bathroom after drinking a Big Gulp. That's the dilemma faced by parents of children born with congenital central hypoventilation syndrome (CCHS). Afflicting about 250 children in the United States, the genetic disease wreaks havoc in areas of the brain that control involuntary actions such as breathing, fluid regulation and heart function.

Ramelteon demonstrates no abuse potential
Results of a clinical study indicated that ramelteon, an investigational compound currently under review by the FDA for insomnia treatment, had no more potential for abuse than placebo in individuals with a history of polydrug abuse. These results, presented at the 2005 American Psychiatric Association Annual Meeting, showed that patients exhibited no abuse potential or behavioral impairment at up to 20 times the proposed therapeutic dose of ramelteon compared to placebo.

Infant Sleep: A Precursor to Adult Sleep?
Sleep is absolutely essential for well-being. Just ask one of the 40 million Americans with sleep disorders who suffer crippling fatigue, impaired judgment, irritability, moodiness, and myriad health problems. Still, its precise function remains unclear. An intriguing role for REM sleep—the stage most closely associated with dreaming—was suggested almost 40 years ago when sleep researchers Howard Roffwarg and William Dement discovered that babies spend far more time in REM sleep than adults—prompting their hypothesis that infant REM sleep plays a role in central nervous system development.
