Randomized Controlled Trial Multicenter Study
A multicenter evaluation of oral pressure therapy for the treatment of obstructive sleep apnea.
We aimed to evaluate the impact of a novel noninvasive oral pressure therapy (OPT) (Winx®, ApniCure) system on polysomnographic measures of sleep-disordered breathing, sleep architecture, and sleep stability in obstructive sleep apnea (OSA). ⋯ Clinically significant improvements in sleep quality and continuity, AHI, ODI, ESS, and overall clinical status were achieved in an easily identified subgroup. OPT was safe and well-tolerated and nightly usage was high.

The evidence concerning the relationship between nonapnea sleep disorders and the risk for type 2 diabetes mellitus (DM) is scant and elusive. Our study aimed to examine if nonapnea sleep disorders increase the risk for DM using a population-based retrospective cohort study from 1997 to 2010. ⋯ Compared to patients without nonapnea sleep disorders, patients with nonapnea sleep disorders had a higher risk for developing DM, especially among those who were less than 40years of age and who had sleep disturbances.

Discrimination between narcolepsy, idiopathic hypersomnia, and behavior-induced inadequate sleep syndrome (BIISS) is based on clinical features and on specific nocturnal polysomnography (NPSG) and multiple sleep latency test (MSLT) results. However, previous studies have cast doubt on the specificity and sensitivity of these diagnostic tools. ⋯ The FREMP stage sequence may be a useful tool in the diagnosis of narcolepsy, particularly in conjunction with sleep-stage sequence analysis of sleep-onset REM periods (SOREMPs) in the MSLT; it also may provide a helpful intermediate phenotype in the clarification of heterogeneity in the N-C diagnostic group. However, larger prospective studies are necessary to confirm these findings.
