L Lerousseau
Excessive daytime sleepiness is a major symptom in cases of the obstructive sleep apnea-hypopnea syndrome. Most often, it is vastly improved by treatment with continuous positive airway pressure (CPAP). The most effective way to confirm its disappearance is through wakefulness maintenance testing. If residual sleepiness remains, despite CPAP, further diagnostic investigation must be carried out. Firstly, it must be assessed whether the treatment is fully effective (apnea hypopnea index<10/h) by examining flow limitations under treatment (polysomnography) and whether it is sufficiently used (>6h/night)...

PURPOSE: A variety of statistical models based on overnight oximetry has been proposed to simplify the detection of children with suspected obstructive sleep apnea syndrome (OSAS). Despite the usefulness reported, additional thorough comparative analyses are required. This study was aimed at assessing common binary classification models from oximetry for the detection of childhood OSAS. METHODS: Overnight oximetry recordings from 176 children referred for clinical suspicion of OSAS were acquired during in-lab polysomnography...

Sleep quality appears to be altered by traumatic brain injury (TBI). However, whether persistent post-injury changes in sleep architecture are present is unknown and relatively unexplored. We conducted a systematic review and meta-analysis to assess the extent to which chronic TBI (>6 months since injury) is characterized by changes to sleep architecture. We also explored the relationship between sleep architecture and TBI severity. In the fourteen included studies, sleep was assessed with at least one night of polysomnography in both chronic TBI participants and controls...

PURPOSE: Sickle cell disease (SCD) imparts an increased risk for obstructive sleep apnea (OSA) in childhood. Studies of pediatric SCD have identified an increased risk for pain and neurologic complications with comorbid OSA. We determined the rate of a broad range of SCD-related medical complications to better characterize the spectrum of SCD complications related to OSA. METHODS: Retrospective chart review at a single hematology clinic identified 641 youth with SCD who received consistent screenings for OSA as part of routine hematological health maintenance visits over an 11-year period...

Importance: Hypertension in childhood may continue into adulthood and lead to adverse cardiovascular outcomes. Evidence suggests that adenotonsillectomy for childhood obstructive sleep apnea (OSA) may be associated with blood pressure (BP) improvement. However, how adenotonsillectomy is associated with BP in hypertensive and nonhypertensive children with OSA remains unclear. Objective: To investigate disparities in BP changes after adenotonsillectomy in hypertensive and nonhypertensive children with OSA...

Insomnia Disorder (ID) is the second-most common mental disorder and has a far-reaching impact on daytime functioning. A meta-analysis indicates that, of all cognitive domains, declarative memory involving the hippocampus is most affected in insomnia. Hippocampal functioning has consistently been shown to be sensitive to experimental sleep deprivation. Insomnia however differs from sleep deprivation in many aspects, and findings on hippocampal structure and function have been equivocal. The present study used both structural and resting-state functional Magnetic Resonance Imaging in a larger sample than previously reported to evaluate hippocampal volume and functional connectivity in ID...

OBJECTIVES: Pediatric obstructive sleep apnea has a relatively high prevalence and has various negative health and behavioral consequences. Among the various complications of pediatric obstructive sleep apnea, growth disturbance is still controversial. METHOD: 745 pediatric subjects with obstructive sleep apnea diagnosed by in-lab polysomnography were enrolled, after excluding ineligible subjects with abnormal growth related factors. Height, weight, and BMI of enrolled patients were measured and statistically converted to z-scores, and the converted data were analyzed statistically with the polysomnographic results...

Sleep apnea (SA), a common sleep disorder, can significantly decrease the quality of life, and is closely associated with major health risk such as cardiovascular disease, sudden death, depression, and hypertension. Normal diagnostic process of SA using polysomnography (PSG) is costly and time consuming. In addition, the accuracy of different classification methods to detect SA varies with the use of different physiological signals. If an effective, reliable, and accurate classification method is developed, then the diagnosis of SA and their associated treatment will be time-efficient and economical...

Study Objectives: Insomnia disorder (ID) is a frequent sleep disorder coupled with increased risks for somatic and mental illness. While subjective complaints are severe, polysomnography (PSG) parameters show only modest differences between groups. REM sleep as the most aroused sleep state may be especially vulnerable to be perceived as wake. To directly assess possible differences, we determined auditory waking thresholds and sleep perception in ID patients and healthy control subjects (GSC) in N2 and REM sleep...

The early prediction of atherosclerosis (AS) is important in the management of obstructive sleep apnea patients (OSA). MicroRNA (miRNA) plays a vital role in the evolution of OSA and AS. Its differential expression may therefore serve as a diagnostic and prognostic biomarker of AS in OSA. The aim of this study was to identify specific serum miRNAs that could serve as a novel screening signature of AS in OSA patients. The specificity and sensitivity of these miRNAs in the early diagnosis of AS in OSA patients were then determined...
