More than a bad night's sleep

Study finds sleep apnea widely undiagnosed among obese type 2 diabetics

Sleep apnea has long been known to be associated with obesity. But a new study published in the June issue of Diabetes Care finds that the disorder is widely undiagnosed among obese individuals with type 2 diabetes – nearly 87 percent of participants reported symptoms, but were never diagnosed.

For those with untreated sleep apnea, it doesn't just mean their sleep is disrupted; existing research shows that it can also mean an increased risk of heart disease and stroke.

"The high prevalence of undiagnosed, and therefore, untreated sleep apnea among obese patients with diabetes constitutes a serious public health problem," said Gary Foster, PhD, lead author and director of the Center for Obesity Research and Education at Temple University.

The new study, called Sleep AHEAD, looked at 306 obese patients with type 2 diabetes already enrolled in the Look AHEAD trial, a 16-site study investigating the long-term health impact of an intensive lifestyle intervention in 5, 145 overweight or obese adults with type 2 diabetes.

Each participant had a sleep study (polysomnogram) that measures various breathing and brain activity during sleep. Participants also filled out a series of questions about symptoms related to sleep (snoring, sleepiness during the day), and had their weight, height, waist and neck circumferences measured.

Researchers found that 86.6 percent of participants had sleep apnea, yet reported never being diagnosed. More than 30 percent of these had between 16 and 20 episodes per hour where they would stop breathing, and 22 percent had more than 30 episodes per hour, considered severe sleep apnea. Most of these also had a larger waist circumference, which researchers found, along with higher BMI, to be significantly associated with sleep apnea.

Obesity has long been known to be associated with sleep apnea, but researchers say that these findings are alarming.

"Doctors who have obese patients with type 2 diabetes need to be aware of the possibility of sleep apnea, even if no symptoms are present, especially in cases where the patient has a high BMI or waist circumference," said Foster.

Currently, more than half of obese or overweight individuals have diabetes, the seventh leading cause of death in the United States.

Other authors on the study were Kelley Borradaile, PhD from Temple University; Mark Sanders, MD, Anne Newman, MD, David Kelley, MD, from the University of Pittsburgh; Richard Millman, MD, Rena Wing, PhD from Brown University; Garry Zammit, MD from Clinilabs; Thomas Wadden, PhD, Valerie Darcey, MS, and Samuel Kuna from the University of Pennsylvania; F. Xavier Pi SUnyer from Columbia University; and the Sleep AHEAD Research Group.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
