University of Chicago scientists have dovered important new relationships between obesity, sleep-disordered breathing (SDB) and cognitive processing among elementary school children.

“The intricate interdependencies between BMI, SDB and cognition shown in our study are of particular importance in children, as their brains are still rapidly developing,” says study author Karen Spruyt, PhD, assistant professor in the Department of Pediatrics at the Pritzer School of Medicine. “Rising rates of obesity in children may amplify these relationships. Public health campaigns targeting obesity should emphasize not only the health benefits but the potential educational benefits of losing weight.”

The findings were published online ahead of print publication in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. Read the rest of this entry

New Home Sleep Testing Classification System

A new classification system detailing the type of signals measured by home sleep testing devices for diagnosing obstructive sleep apnea (OSA) appears in the latest issue of the Journal of Clinical Sleep Medicine.

The proposed system categorizes home sleep testing devices, called out-of-center (OOC) testing devices in the paper, based on measurements of Sleep, Cardiovascular, Oximetry, Position, Effort, and Respiratory (SCOPER) parameters. Criteria for evaluating the devices are also presented, based on pre-test and post-test probabilities.

The first widely used classification system for describing sleep testing devices was published by the American Academy of Sleep Medicine (AASM) in 1994. Read the rest of this entry

Provent Sleep Apnea Therapy Show High Compliance

A study appearing in the November 2011 issue of the Journal of  Clinical Sleep Medicine finds that obstructive sleep apnea (OSA)  patients treated with Provent Sleep Apnea Therapywere not only compliant  with the therapy but also showed a reduction in apnea-hypopnea index  (AHI).

“This study provides further validation that Provent Therapy is an  effective treatment for some OSA patients as it reduces daytime  sleepiness, apnea-hypopnea index (AHI), and snoring associated with this  prevalent condition,” said Meir Kryger, MD, of Gaylord Sleep Medicine  and past president of the American Academy of Sleep Medicine.

“Patients  reported wearing the device almost 90% of the nights, which represents  very high compliance. The current gold standard, continuous positive  airway pressure (CPAP) is very effective but many patients do not use it  adequately. Provent represents an important new treatment option for  many obstructive sleep apnea patients.” Read the rest of this entry

A newly concluded research study findings published online in the European Respiratory Journal, evaluated the impact a Mediterranean diet can have on obese people with sleep apnea, compared to those on a prudent diet.The study revealed that Mediterranean diet combined with physical activity can help to improve some of the symptoms of sleep apnea.

Obstructive sleep apnea syndrome (OSAS) causes frequent pauses of breathing to occur during sleep, which disrupts a person’s normal sleeping pattern. It is one of the most prevalent sleep-related breathing disorders with approximately 2-4% of the adult population experiencing the condition. This percentage increases up to 20-40% with obesity, and weight loss is often an essential part of the recommended treatment plan.

The researchers, from the University of Crete in Greece, examined 40 obese patients suffering from OSAS. Twenty patients were given a prudent diet to follow, while the other 20 followed a Mediterranean diet. Both groups were also encouraged to increase their physical activity, mainly involving walking for at least 30 minutes each day.

In both groups, the patients also received continuous positive airway pressure (CPAP) therapy which involves wearing a mask that generates an air stream, keeping the upper airway open during sleep. Read the rest of this entry

Aviisha Medical Institute, LLC has released its long-anticipated Guide  to Obstructive Sleep Apnea. The guide was authored by Aviisha’s Medical  Director, Dr. Avi Ishaaya, and is the only online guide written by a certified  sleep physician. The guide is free to download and share and can be accessed at

“In addition to testing and treating patients, one of our main goals at the  institute is raising awareness about sleep apnea,” said Dr. Avi. “Sleep apnea  affects one in every five to fifteen people, but 80-90% of them are undiagnosed  and in need of treatment. We created this ebook to help spread the word about  sleep apnea.”

The ebook is packed useful information about diagnosing and treating sleep  apnea, including:

  •      Biology and Causes of Sleep Apnea
  •     Dangers and Complications
  •     Risk Factors
  •     Screening for OSA Read the rest of this entry

Apnex Medical, Inc., has received CE Mark approval for its Hypoglossal Nerve Stimulation (HGNS®) System for use by people who suffer from obstructive sleep apnea (OSA). The system was approved for sale in Europe based on the positive results of two clinical studies conducted in the United States and Australia. In those studies, the majority of patients demonstrated a significant reduction in their obstructive sleep apnea as well as substantial improvements in the quality of their sleep, quality of life, and overall health.

“CE Mark approval is an important confirmation of the substantial benefits that patients receive from our HGNS therapy for obstructive sleep apnea and is a key milestone for our company,” said Chas McKhann, Apnex Medical President and CEO. Read the rest of this entry

(Reuters Health) – New research shows high rates of sleep disorders among veterans of America’s wars in Iraq and Afghanistan who have post-traumatic stress disorder (PTSD) or head injuries.

The study conducted at Walter Reed Army Medical Center in Washington, DC, found that among some 300 soldiers with PTSD, head injuries or both, more than half had sleep apnea — a serious interruption of breathing during sleep — and nearly half had insomnia.

Sleep complaints were universal,” wrote Dr. Jacob Collen and his colleagues in their research summary. Collen’s team presented their findings this week at the annual meeting of the American College of Chest Physicians in Honolulu.

The researchers studied 135 soldiers with PTSD, 116 with traumatic brain injury and 66 with both conditions.

Sleep testing performed on most of the patients found obstructive sleep apnea in 56 percent of them and insomnia in 49 percent. Read the rest of this entry

SleepApneaDisorder/[ Press Release ]/ Falls Church, Virginia. / Obstructive sleep apnea, caused by narrowing or blockage of the airways when a person is asleep affects about 20% of the population. Typically a person with OSA will begin snoring loudly on falling asleep. If not treated, obstructive sleep apnea (OSA) can increase a person’s risk of death.  It is not clear whether an enlarged thyroid gland, known as a goiter, can worsen cause or worsen symptoms of OSA by compressing the airway.

Alexandra Reiher, MD, and colleagues from the University of Wisconsin, Madison, evaluated the impact of goiter on OSA by assessing OSA symptoms such as snoring before and after thyroidectomy to remove all or part of and enlarged thyroid gland. Patients who reported symptoms of OSA included snoring were asked to complete a questionnaire before and 8 weeks after undergoing thyroidectomy. Data presented today at the 81st Annual Meeting of the American Thyroid Association showed significantly fewer patients (51% versus 71%) were considered to be at high risk for OSA following surgical reduction or removal of the thyroid gland. Symptom scores improved substantially after thyroidectomy, including a significant decrease in snoring frequency and lower scores on the question of whether the snoring bothered others.

Obstructive sleep apnea is obviously a complex problem with numerous causes, but we find it encouraging that thyroidectomy alone can provide significant improvements in nearly a third of patients, regardless of gland size,” said study author Rebecca Sippel, MD, Assistant Professor, Division of General Surgery, and Chief, Section of Endocrine Surgery, at the University of Wisconsin School of Medicine and Public Health.

RespireAide Sleep Apnea Device Gets Patent

Harry Cutler, a sleep apnea patient, has been awarded patent protection in the United Kingdom. The patent protects a medical device created initially to treat Mr. Cutler’s own obstructive sleep apnea (OSA) which afflicts from 12% to 25% of the population. The device also reduces or eliminates snoring, one of the primary side effects of OSA. Unlike other oral appliances, it can be used by people with loose teeth, dentures, or no teeth at all, thereby eliminating costly dental preparation. It is being marketed as the “RespireAide Sleep Apnea Solution”.

In this case, necessity was indeed the mother of invention. Underemployed at the time and without insurance, Cutler’s sleep apnea became severe. “I was falling asleep while driving to work, in the middle of the day! I had to do something,” said Cutler.

He researched the condition and began to fashion a solution mostly from items found around the house or purchased from the local hardware and sporting goods stores. “The initial device was somewhat crude, but it did help. Over the following six years, using myself as a test subject, I refined and improved the device with the goal of creating an acceptable combination of comfort and effectiveness. The resultant device bears little resemblance to the original,” he added. Read the rest of this entry
