Obstructive sleep apnea (OSA) is a risk factor for significant perioperative complications. This national survey study sought to determine the attitudes of physicians involved in the perioperative care of OSA patients. ⋯ The majority of physicians in this survey felt OSA was a significant risk factor for perioperative complications and most reported experience with OSA patients having an adverse outcome. Perioperative management guidelines for OSA are not available at most institutions. Further work is needed to help physicians identify and intervene on patients with OSA in the perioperative setting before adverse events develop.

The primary aim of the current study was to test the hypothesis that there is a seasonal component to snoring and obstructive sleep apnea (OSA) through the use of Google search engine query data. ⋯ Our findings indicate that there are significant seasonal trends for both snoring and sleep apnea internet search engine queries, with a peak in the winter and early spring. Further research is indicated to determine the mechanisms underlying these findings, whether they have clinical impact, and if they are associated with other comorbid medical conditions that have similar patterns of seasonal exacerbation.

Observational Study
Utility of extended cardiac monitoring to detect atrial fibrillation in patients with severe obstructive sleep apnea.
The relationship between obstructive sleep apnea (OSA) and increased risk for atrial fibrillation (AF) has been well established in previous studies. The relationship between OSA and silent AF is unknown. We hypothesized that patients with OSA but no known history of AF are at an increased risk for the arrhythmia and may be detectable by prolonged electrocardiogram (ECG) monitoring. In this study, we examined whether 7 days of extended cardiac monitoring with an ECG event recorder is an effective screening tool to detect intermittent, silent AF in patients with severe OSA. ⋯ In patients with severe OSA without a known history of AF, 7 days of extended cardiac monitoring with an ECG event recorder did not detect clinically meaningful, silent AF.

We sought to assess the rate of sleep complaints and sleep disorders among active duty soldiers with deployment-related PTSD and to determine whether any clinical features differentiated those with sleep disorders. ⋯ Sleep complaints are common among soldiers with PTSD. We observed significantly higher rates of OSAS among those without physical injuries, raising the possibility that underlying sleep-disordered breathing is a risk factor for the development of PTSD. This potential association requires further validation.

Electronic noses represent a technique for the measurement of exhaled breath volatile compound pattern which can discriminate patients with obstructive sleep apnoea (OSA) from control subjects. Although overnight changes in circulating biomarkers were reported, this effect on the exhaled volatile compound pattern has not been studied before. We aimed to compare breath patterns in the evening and in the morning in patients with OSA and to study the ability of the electronic nose to distinguish patients from controls based on these exhaled volatile patterns. ⋯ Evening and morning exhaled volatile compound patterns are different in OSA. This might affect the ability of electronic noses to identify this disorder. Overnight alterations in volatile substances need to be taken into account during exhaled breath measurements in OSA.
