The Cincinnati team found that about 21 percent of young adult women with asthma experienced habitual snoring, the primary symptom of obstructive sleep apnea.
These findings, the researchers say, disprove a long-held notion that obstructive sleep apnea predominantly affects males, and highlights the importance of identifying specific groups of women who are at high risk for the condition.
This study is reported in the August edition of the journal Annals of Allergy, Asthma and Immunology.
"For a long time physicians believed that men were more likely than women to get obstructive sleep apnea, but we've shown that's not necessarily true," says Maninder Kalra, MD, lead author of the study and assistant professor of pediatrics at the UC College of Medicine. "Our study reinforces the need for awareness and early detection of the disease in women who are at increased risk for breathing disorders related to sleep."
Obstructive sleep apnea occurs when airways in the nose, mouth and throat narrow and disrupt a person's ability to breathe properly--primarily during sleep. When this happens, breathing can stop for short periods and cause blood-oxygen levels to become low.
Left untreated, obstructive sleep apnea can lead to impaired memory, mood swings, restless sleep, and extreme day-time fatigue. Long term effects can include higher blood pressure and decreased heart function.
"Physicians need to know the risk factors that predispose a patient to obstructive sleep apnea," Kalra adds, "so we can get those patients in for a conclusive test--such as a sleep study--and start treatment sooner."
The UC-led research team also found that women who smoked cigarettes were at a higher risk for snoring than those who did not smoke.
Researchers collected data from 677 mothers of infants enrolled in the UC environmental health department's Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) about their history of snoring, respiratory symptoms and cigarette smoking.
The CCAAPS, funded by the National Institute of Environmental Health Sciences, is a five-year study examining the effects of environmental particulates on childhood respiratory health and allergy development.
All families enrolled in the study had at least one confirmed allergy, in either the mother or the father. Environmental tobacco smoke exposure and any history of asthmatic conditions were measured by questionnaire. Researchers used this data to compare snorers with non-snorers and determine risk factors for snoring in women under 50.
Traditional treatment options for obstructive sleep apnea include surgery to remove tissue in the throat and use of a mask during sleep that applies continuous pressure to the airways to help restore airflow. According to the American Lung Association, more than 18 million Americans have sleep apnea.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
