Observational Study
Presence and severity of obstructive sleep apnea and remote outcomes of atrial fibrillation ablations - a long-term prospective, cross-sectional cohort study.
Prior studies suggested that obstructive sleep apnea (OSA) promotes recurrence of arrhythmia in patients after atrial fibrillation (AF) ablation. ⋯ OSA is highly prevalent in AF patients. The presence of OSA lowers chances on successful AF ablation. Early screening, and treatment for OSA in AF patients, may improve low success rates of AF ablation procedures.

Physiologic changes in the cardiac, respiratory, and renal systems in pregnancy likely impact ventilatory control. Though obstructive sleep apnea and snoring are common in the pregnant population, the predisposition to central respiratory events during sleep and the prevalence of such events is less well studied. The aim of this study was to assess the presence of central apneas during sleep in pregnant women and non-pregnant controls suspected of sleep disordered breathing. ⋯ Despite some physiologic changes of pregnancy that impact ventilatory control, the prevalence of central sleep apnea was low in our sample of overweight pregnant women with sleep-disordered breathing.

The goal of this study was to identify the prevalence and clinical correlates and severity of restless legs syndrome (RLS) among pregnant women in mainland China. ⋯ In our study, RLS was frequent in pregnant Chinese women, and anemia was identified as an independent predictor of the disease. Further, most participants reported their symptoms during the third trimester, and the severity of RLS and sleep disorders of participants was more prominent in the third trimester.

Randomized Controlled Trial Comparative Study
Comparison of three sedation regimens for drug-induced sleep endoscopy.
Drug-induced sleep endoscopy (DISE) allows for direct airway observation in patients with obstructive sleep apnea. This study compared the safety profiles and efficacies of three regimens for DISE. ⋯ The propofol-remifentanil combination was associated with a higher incidence of desaturation. The dexmedetomidine-remifentanil combination was associated with inadequate sedation in one half of the patients, even though it produced less respiratory depression. Addition of remifentanil reduced the cough reflex.
