Results indicate that people with an apnea-hypopnea index (AHI), the average of the combined episodes of apnea and hypopnea that occur per hour of sleep, of over 15 had an increase in body mass index (BMI) of 0.52 kg/m2 compared to those with an AHI between 5 and 15, who saw an increase of 0.22 kg/m2.
According to lead author Mark Brown, MD, Department of Psychiatry at the University of Arizona College of Medicine in Tucson, people suffering from more severe OSA may be more likely to gain more weight than those with less severe OSA over time.
"OSA is a disorder characterized by decreases or cessation of breathing during sleep. Obesity is a known risk factor for the disorder; however, it is hypothesized that the effects of OSA itself may predispose patients to weight gain," said Brown.
The study included data from 3,001 men and women from the Sleep Heart Health Study (SHHS) with an average age of 62.19. Of the sample, 55.2 percent of participants were female and 76.1 percent were Caucasian. Participants were classified as having no (AHI of less than 5), moderate (AHI between 5 and 15), and severe OSA (AHI of over 15). Weight and polysomnograph information were collected. Linear regression was used to examine the association between AHI groups and the change in BMI over approximately five years. The final model was adjusted for age, gender, race, initial BMI and change in AHI over 5 years.

SLEEP 2009 will bring together an international body of 6,000 leading researchers and clinicians in the field of sleep medicine to present and discuss new findings and medical developments related to sleep and sleep disorders.
More than 1,300 research abstracts will be presented at SLEEP 2009, a joint venture of the AASM and the Sleep Research Society. The scientific meeting will bring to light new findings that enhance the understanding of the processes of sleep and aid the diagnosis and treatment of sleep disorders such as insomnia, narcolepsy and sleep apnea.Abstract Title: Sleep-Disorded Breathing and Weight Gain: The Sleep Heart Health Study.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
