Poor sleep quality during pregnancy is associated with adverse obstetric and neuropsychiatric outcomes. Despite its routine use as a sleep quality assessment scale among men and non-pregnant women, the psychometric properties of the Pittsburgh Sleep Quality Index (PSQI) have not been assessed among US pregnant women. We sought to evaluate the construct validity and factor structure of the PSQI among 1488 pregnant women. ⋯ The PSQI has good construct validity and reliability for assessing sleep quality among pregnant women.

Comparative Study
Comparison of the upper airway dynamics of oronasal and nasal masks with positive airway pressure treatment using cine magnetic resonance imaging.
It is known that oronasal masks are not as effective at opening the upper airway compared to nasal only continuous positive airway pressure (CPAP) masks in patients with sleep-disordered breathing. However, the physiological mechanism for this difference in efficacy is not known; although, it has been hypothesized to involve the retroglossal and/or retropalatal region of the upper airway. The objective of this study was to investigate differences in retroglossal and retropalatal anterior-posterior space with the use of oronasal vs. nasal CPAP masks using real-time cine magnetic resonance imaging (cMRI). ⋯ Our study confirmed previous findings showing differences in treatment efficacy between oronasal and nasal mask styles. We have shown anatomic evidence that the nasal mask is more effective in opening the upper airway compared to the oronasal mask in the retropalatal region.

Observational Study
Sleep disorders in pregnancy and their association with pregnancy outcomes: a prospective observational study.
Sleep disturbances such as insomnia, nocturnal awakenings, restless legs syndrome, habitual snoring, and excessive daytime sleepiness are frequent during pregnancy, and these have been linked to adverse maternal and fetal outcomes. ⋯ Snoring and high-risk MBQ in pregnant women are strong risk factors for GH and CS. In view of the significant morbidity and health care costs, simple screening of pregnant women with questionnaires such as MBQ may have clinical utility.

Randomized Controlled Trial Multicenter Study Comparative Study
Home-use servo-ventilation therapy in chronic pain patients with central sleep apnea: initial and 3-month follow-up.
Opioid treatment of non-malignant chronic pain can result in hypoxemia, hypercarbia, and central sleep apnea. The aim of this study was to determine the initial efficacy of auto servo-ventilation (ASV) and after 3 months of home use. ⋯ Initial and home use of ASV for 3 months resulted in significantly lower AHI, CAI, and OAI. This reduction attests to the efficacy of ASV treatment in chronic pain patients on high doses of opioids.

Comparative Study
Utility of the STOP-BANG components to identify sleep apnea using home respiratory polygraphy.
Utility of questionnaires to estimate the probability of obstructive sleep apneas (OSA) is varying, and it is challenging to know the performance of STOP (Snore, Tired, Observed apnea, and Pressure)-BANG (BMI, Age, Neck and Gender) with simplified methods. To assess the performance of STOP-BANG and its ability to predict sleep apnea in patients with high pre-test like-hood to present OSA referred for a home respiratory polygraphy (RP) were studied. ⋯ STOP-BANG shows different discrimination power for AHI >5 and ≥30/h using RP. Five components in any combination have acceptable diagnostic S to identify patients with severe OSA. STOP-BANG performed best to identify AHI ≥30/h.
