Randomized Controlled Trial Comparative Study
Improving Daytime Functioning, Work Performance, and Quality of Life in Postmenopausal Women With Insomnia: Comparing Cognitive Behavioral Therapy for Insomnia, Sleep Restriction Therapy, and Sleep Hygiene Education.
Insomnia is a chief complaint among postmenopausal women, and insomnia impairs daytime functioning and reduces quality of life. Recent evidence supports the efficacy of cognitive behavioral therapy for insomnia (CBTI) for menopausal insomnia, but it remains unclear whether treating insomnia improves daytime function in this population. This study evaluated whether CBTI improves daytime fatigue, energy, self-reported sleepiness, work productivity, and quality of life in postmenopausal women with insomnia, and whether sleep restriction therapy (SRT)-a single component of CBTI-is equally efficacious. ⋯ Registry: ClinicalTrials.gov; Title: Behavioral Treatment of Menopausal Insomnia; Sleep and Daytime Outcomes; Identifier: NCT01933295; URL: https://clinicaltrials.gov/ct2/show/record/NCT01933295.

Randomized Controlled Trial
Effects of Medical Therapy on Mild Obstructive Sleep Apnea in Adult Patients.
Patients with obstructive sleep apnea (OSA) have been shown to have high levels of inflammatory markers. Anti-inflammatory treatment with montelukast and intranasal steroids have demonstrated efficacy for mild OSA in children; this has not been fully evaluated in adults. This study investigated the response of mild OSA in adults to anti-inflammatory medical therapy. ⋯ Registry: ClinicalTrials.gov; Title: Montelukast and Nasa ICS for Treatment of Mild Obstructive Sleep Apnea in Adults; Identifier: NCT01089647; URL: https://clinicaltrials.gov/ct2/show/record/NCT01089647.

Air Pollutants Are Associated With Obstructive Sleep Apnea Severity in Non-Rapid Eye Movement Sleep.
The relationship between seasonal variation of obstructive sleep apnea and ambient temperature and pollutants has been inconsistent in previous studies. It is also unknown whether the seasonal variation in apnea-hypopnea index influences continuous positive airway pressure treatment dose. This study aims to examine the seasonality of obstructive sleep apnea and continuous positive airway pressure treatment, and the association between air pollutants and apnea-hypopnea index in adults with different sleep apnea severity during different sleep stages. ⋯ An adjustment for continuous positive airway treatment dose by season is not warranted. Protection for air pollutant-vulnerable groups should be provided. The exact mechanism of the associations between apnea-hypopnea index and air conditions only in non-rapid eye movement sleep must be clarified.

Comparative Study
Adherence to Positive Airway Pressure for the Treatment of Obstructive Sleep Apnea in Children With Developmental Disabilities.
To determine whether adherence to positive airway pressure (PAP) differs in children with developmental disabilities (DD) compared to typically developing (TD) children. ⋯ Children with DD had better PAP adherence expressed as percentage of nights used than TD children. Hours of usage on nights used at 3 and 6 months were similar between groups and improved over time. Higher income and titration at or before 6 months were predictive of adherence in all children. These findings indicate that children with DD can successfully wear PAP.

Controversy exists as to whether elevated loop gain is a cause or consequence of obstructive sleep apnea (OSA). Upper airway surgery is commonly performed in Asian patients with OSA who have failed positive airway pressure therapy and who are thought to have anatomical predisposition to OSA. We hypothesized that high loop gain would decrease following surgical treatment of OSA due to reduced sleep apnea severity. ⋯ Registry: ClinicalTrials.gov, Title: The Impact of Sleep Apnea Treatment on Physiology Traits in Chinese Patients With Obstructive Sleep Apnea, Identifier: NCT02696629, URL: https://clinicaltrials.gov/show/NCT02696629.
