Researchers in Spain have identified a link between obstructive sleep apnea and cancer growth in mice. The intermittent interruption of breathing that occurs in patients with obstructive sleep apnea (OSA) has shown association with enhanced proliferation of melanoma cancer cells and increased tumour growth in mice.

“To our knowledge, this study is the first one providing experimental evidence that a high-rate intermittent lack of oxygen, or hypoxia, mimicking the one experienced by obstructive sleep apnea (OSA) patients enhances tumour growth,” said Ramon Farre, professor of physiology at the University of Barcelona School of Medicine Biophysics and Bioengineering Lab.

Scientists say sleep deprivation also slows your metabolism down as well. Researchers from Uppsala University in Sweden found that insomnia could encourage you to pile on the pounds by slowing down the rate at which the body burns calories.

Study leader Christian Benedict, said: ‘Our findings show that one night of sleep deprivation acutely reduces energy expenditure in healthy men, which suggests sleep contributes to the acute regulation of daytime energy expenditure in huma

Older studies have linked sleep deprivation with weight gain and also shown how disrupted sleep also disrupts levels of stress – and hunger-related hormones during waking hours. Read the rest of this entry

Obese, asthmatic, anxious or depressed children are more likely to experience excessive daytime sleepiness, or EDS, according to Penn State College of Medicine sleep researchers.

“Although excessive daytime sleepiness in children is commonly assumed by physicians and the public to be the result of sleep-disordered breathing or inadequate sleep, our data suggest that EDS in young children is more strongly associated with obesity and mood issues as it is in adults,” said Edward Bixler, professor of psychiatry and vice chair of research at the Sleep Research and Treatment Center.

Excessive daytime sleepiness is the inability to stay awake during the day, while sleep-disordered breathing is a group of disorders that includes sleep apnea, characterized by pauses in breathing. Read the rest of this entry

Removing enlarged tonsils and adenoids may help prevent high blood pressure and heart damage in children who suffer from obstructive sleep apnea (OSA), according to a study conducted at Cincinnati Children’s Hospital Medical Center. In some children with obstructive sleep apnea (OSA), adenotonsillectomy can result in significantly lower blood pressure within 24 months of the procedure.

The results will be presented at the ATS 2011 International Conference in Denver.

Children with enlarged tonsils and adenoids are particularly prone to developing obstructive sleep apnea (OSA), said study lead author Lisa Burns, MD, (Pulmonary Fellow at Cincinnati Children’s Hospital Medical Center). And, in children and adults, obstructive sleep apnea (OSA) has been linked with elevations in both daytime and nighttime blood pressureobstructive sleep apnea (OSA) can also interfere with the normal “dip” in blood pressure levels that occur during sleep. Persistent elevations in blood pressure can result in organ damage, including heart damage. Read the rest of this entry

A study presented today at the American Psychiatric Association’s annual meeting suggests that sleep disturbances like obstructive sleep apnea (OSA), excessive awakening and insomnia, may be a normal result of combat experience, rather than a symptom of post-traumatic stress disorder (PTSD), traumatic brain injury (TBI), major depression or other psychiatric conditions.

The retrospective study, which will be published this summer as “Sleep Disruption Among Returning Combat Veterans from Iraq and Afghanistan” in the peer-reviewed journal Military Medicine, examined the electronic medical records of recently redeployed soldiers complaining of sleep disturbances. The purpose of the study was to uncover the relationship between common combat-related conditions among active duty military personnel and the frequency of a diagnosis of obstructive sleep apnea (OSA ) and other sleep problems.

Obesity Among Children Rises in Cincinati

Childhood obesity in Ohio is at 33.3% according to the National Conference of State Legislatures. Cincinnati weight loss problems mount as the state will pay $3.304 billion in annual medical costs of obesity.

One in three children are overweight or obese. Childhood obesity has increased over 300% in the past 30 years according to the CDC (Center for Disease Control). Obesity among children aged 6 to 11 years increased from 6.5% in 1980 to 19.6% in 2008. Obesity among adolescents aged 12 to 19 years increased from 5.0% to 18.1% during the same time period.

Your Laziness Is Costing You Money

Sleeping the day away can lead to insomnia, and that can be costly to treat. “This can be fairly common when people don’t have a regular schedule, if they’re on vacation, or unemployed,” says Dr. Michael J. Breus, WebMD’s sleep expert and author of the Sleep Doctor’s Diet Plan.

The insomnia borne of oversleep can lead to obstructive sleep apnea and hypertension; co-payments for related medications run $30 to $40 per month. Sleep aids like Tylenol PM run another $15 a month. And being up all night in the Internet age can lead to torching an extra few dollars on books at or downloads at Apple’s iTunes store. [ Read Complete Post at FORBES … ]

In a recently concluded research study the researchers aimed to evaluate the efficacy of oral appliance (OA) treatment for subjects with severe obstructive sleep apnea (OSA) and to determine the dental parameters associated with treatment outcomes.
This study uses a prospective longitudinal design. Consecutive Chinese subjects with severe obstructive sleep apnea (OSA ) who refused continuous positive airway pressure treatment were recruited. Their dental measurements were taken from lateral cephalometric radiographs. Polysomnograms with OA were repeated at 3 months and 1 year. Blood pressure was taken in the morning after sleep studiesRead the rest of this entry

Excessive daytime sleepiness (EDS) is a major but not universally present feature of obstructive sleep apnea syndrome (OSAS). The latter has been associated with glucose dysmetabolism and insulin resistance. The aim of this study was to examine the role of EDS by investigating potential differences between somnolent and non-somnolent OSAS patients in glucose metabolism, insulin resistance, and levels of cardiovascular risk factors.

Methods Included were 25 newly diagnosed otherwise healthy OSAS patients, reporting EDS and 25 age- and BMI-matched, non-somnolent OSAS patients, who served as controls. Fasting glucose and insulin levels, as well as homeostatic model assessment of insulin resistance (HOMAIR) index, levels of hs-CRP, and lipidemic profile were measured. Read the rest of this entry

Graymark Healthcare, Inc., the nation’s second largest  provider of diagnostic sleep services and an innovator in comprehensive care for  obstructive sleep apnea (OSA), has closed the sale of its Nocturna East Sleep  Centers unit for $2.5 million in gross cash proceeds.

The sale comprised a total of eight stand alone sleep centers, seven located  in western New York and one in Florida. Given that the company only performed  diagnostic sleep tests at these locations, the sale of this asset is expected to  have no effect on Graymark’s recurring revenue re-supply business.
