Researchers from the University of Toledo Medical College in Ohio followed 152 patients who underwent CPAP therapy for 1 month. Of the patients, 119 (78 percent) gained an average of 3 lbs. Weight gain occurred in 81 percent of men and 73 percent of women.

But researchers at Saint Louis University say further research is needed to determine if surgery is the best option for these patients. "We know surgery is associated with improvements in children with sleep apnea, but this research will be the first to allow us to investigate whether or not the surgery causes those improvements," says Ron Mitchell, M.D. Sleep / Sleep Disorders / Insomnia Wed, 04 Nov 2009 04:00:00 PST http://www.medicalnewstoday.com/articles/169775.php http://www.medicalnewstoday.com/articles/169775.php Night-shift workers should avoid drinking coffee if they wish to improve their sleep, according to research published in the journal Sleep Medicine. A new study led by Julie Carrier, a Université de Montréal psychology professor and a researcher at the affiliated Hôpital du Sacré-Coeur Sleep Disorders Centre, has found the main byproduct of coffee, caffeine, interferes with sleep and this side-effect worsens as people age.

Researchers from Kosair Children's Hospital in Kentucky conducted before and after chart reviews of 292 patients younger than 18 years who were hospitalized with status asthmaticus.

It occurs when there is an accidental loss of urine during sleep. Bedwetting is also known as nocturnal enuresis or nighttime incontinence. It is normal in children who are under five years old. At this age, nighttime bladder control may not be established. Bedwetting is the most common pediatric-health issue. Studies show that parents become worried too quickly because they expect children to stay dry too early.

New research presented at CHEST 2009, the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), found that nearly 1 in 4 patients with OSA suffers from nighttime teeth grinding; this seems to be especially more prevalent in men and in Caucasians compared with other ethnic groups.

A new study presented at CHEST 2009, the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), found that golfers with obstructive sleep apnea (OSA) who received nasal positive airway pressure (NPAP) for their disorder improved their daytime sleepiness scores and lowered their golf handicap by as much as three strokes.

The study, presented at CHEST 2009, the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), found that, overall, non-African-American (NAA) patients experienced RLS four times more often than African-Americans (AA).

GE Sensing & Inspection Technologies (NYSE: GE) has developed the Nova Pressure Amplified (NPA) series of pressure sensors for medical devices. Small and effective, the NPA is a critical component in creating cost-effective sleep apnea monitors that are more accurate and reliable than those currently on the market.

Findings suggest that this general improvement in sleep is likely to result from the removal of work-related demands and stress rather than from actual health benefits of retirement. Results show that the odds of having disturbed sleep in the seven years after retirement were 26 percent lower (adjusted odds ratio of 0.

This use of rule-based strategies in a task in which information-integration strategies are optimal can lead to potentially devastating errors when quick and accurate categorization is fundamental to survival.

Endemic countries have now begun the process of ordering the new combination treatment and kits through the World Health Organization (WHO). Developed by DNDi and its partners, NECT cuts the cost of treatment by half and significantly reduces the burden on health workers.

The NDA, submitted by Transcept in September 2008, seeks approval to market Intermezzo® for use as-needed for the treatment of insomnia when a middle of the night awakening is followed by difficulty returning to sleep.

Research published in BioMed Central's open access journal, Arthritis Research & Therapy found that inflammation is associated with heightened pain sensitivity at joint sites, whereas increased sleep problems are associated with heightened pain sensitivity at both joint and non-joint sites.

Just as important, the team believes that the cognitive deficits caused by sleep deprivation, such as an inability to focus, learn or memorize, may be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain.

Researchers found that mice housed in a lighted room 24 hours a day exhibited more depressive symptoms than did similar mice that had a normal light-dark cycle.

Circadian rhythm is the roughly 24-hour cycle of physiological activities of humans, animals and even bacteria, Shi explains.

The findings offer insight into the neurobiological factors behind the obesity epidemic in the United States and other developed countries.

Results show improvement in typical OSA symptoms including snoring, daytime sleepiness, impaired vigilance, poor quality of life and mood after the completion of a 16-week diet and exercise program.

These babies are therefore often given caffeine because of its qualities as a respiratory stimulant. Until recently, the long-term effects of this treatment in humans have not been examined.

The research, conducted in collaboration with scientists at the Mayo Clinic, is published in the September issue of the Mayo Clinic Proceedings.

Understanding how the human biological clock works is an essential step toward correcting sleep problems like insomnia and jet lag. Sleep / Sleep Disorders / Insomnia
