Obstructive sleep apnea (OSA) is a highly prevalent condition related to several cardiovascular complications. We assessed the effects of continuous positive airway pressure (CPAP) treatment on myocardial performance and various somatometric parameters in patients with severe OSA receiving CPAP. ⋯ CPAP therapy in OSA patients was found to improve right heart chambers remodeling and performance as well as somatometric characteristics. The impact of CPAP on LV performance seems less pronounced.

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.

Comparative Study
Diagnostic accuracy of sleep bruxism scoring in absence of audio-video recording: a pilot study.
Based on the most recent polysomnographic (PSG) research diagnostic criteria, sleep bruxism is diagnosed when >2 rhythmic masticatory muscle activity (RMMA)/h of sleep are scored on the masseter and/or temporalis muscles. These criteria have not yet been validated for portable PSG systems. This pilot study aimed to assess the diagnostic accuracy of scoring sleep bruxism in absence of audio-video recordings. ⋯ Although the absence of audio-video recording, the diagnostic accuracy of assessing RMMA with portable PSG systems appeared to remain good, supporting their use for both research and clinical purposes. However, the risk of moderate overestimation in absence of audio-video must be taken into account.

Comparative Study
Critical evaluation of screening questionnaires for obstructive sleep apnea in patients undergoing coronary artery bypass grafting and abdominal surgery.
Obstructive sleep apnea (OSA) is an independent risk factor for complications after surgery. However, OSA remains largely under recognized, and questionnaires designed to detect OSA have shown inconsistent results. Patients with cardiovascular diseases may not present with the typical symptoms of OSA. We therefore sought to compare the performance of screening questionnaires of patients referred for coronary artery bypass grafting (CABG) versus abdominal surgery (Abd surgery). ⋯ Presenting clinical characteristics of OSA are modulated by the population evaluated and may affect the performance of screening questionnaires.

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.
