Aim: Obstructive sleep apnea (OSA) is characterized by repetitive upper airway collapse during sleep, resulting in frequent cortical arousals. However, currently used frequency-based arousal metrics do not sufficiently capture the heterogeneity and clinical significance of arousal responses. The odds ratio product (ORP) is a novel electroencephalographic marker that provides a continuous assessment of sleep depth and has the potential to serve as an objective measure of arousal intensity.

We investigated whether K-complex metrics (frequency, density, duration, amplitude) independently predict psychomotor vigilance in patients with OSA.
Methods: In 140 young and middle-aged adults, K-complexes were automatically detected via a U-Net neural network analyzing F3-M2 electroencephalogram recording.
Background: Obstructive sleep apnea (OSA) is one of the leading causes of sleep disorders and often exhibits psychological impairments. Brain asymmetry (BA), a recognized marker of psychological traits, has been found to be significantly elevated in OSA and associated with anxiety and personality traits. However, evidence for a causal relationship between BA and respiratory events remains lacking.

Background: Sleep patterns, including daytime napping and nighttime sleep duration, have complex relationships with cognitive health, yet the nonlinear associations across diverse populations remain underexplored.
Methods: Utilizing harmonized cognitive assessment protocol from the China Health and Retirement Longitudinal Study (CHARLS-HCAP) and the Survey of Health, Ageing, and Retirement in Europe(SHARE-HCAP). Cognitive function was assessed based on Minimum Mental State Examination (MMSE), Brief Community Screening Instrument-Dementia (BCSID,10/66).
Study Objectives: Obstructive sleep apnea (OSA) disrupts sleep, leading to cognitive impairment and sleepiness, but risk stratification remains unclear. We developed an EEG-based arousal marker to quantify sleep fragmentation and assessed its associations with neurocognitive function and daytime sleepiness.
Methods: Arousal intensity was derived from EEG signals in 1070 APPLES (Apnea Positive Pressure Long-term Efficacy Study) study participants.

Background: Decision-making on how to conduct the concurrent hearing and genetic screening of newborns lacks a health economics basis. To estimate the cost-effectiveness of different newborn hearing screening strategy is necessary.
Methods: A decision tree for a simulated cohort population of 9.

Electroencephalography (EEG) is widely utilized for train driver state detection due to its high accuracy and low latency. However, existing methods for driver status detection rarely use the rich physiological information in EEG to improve detection performance. Moreover, there is currently a lack of EEG datasets for abnormal states of train drivers.

Previous observational studies showed associations between obstructive sleep apnea (OSA) and depression and other negative moods. However, the causality has not been determined. Single nucleotide polymorphisms were identified as instrumental variables by screening from genome-wide association studies.
View Article and Find Full Text PDFBackground: Sleep duration (SD) is a critical determinant of health, with both short and long SD associated with increased risks of morbidity and mortality. However, distinct ages may exhibit unequal sleep needs. Few studies have addressed the modulation of age on SD associated all-cause mortality (AM).

However, PSG can be expensive and is often limited in availability. This study aimed to develop a cost-effective diagnostic strategy by integrating a screening model with PSG.

Purpose: To evaluate the correlation between median frequency (MF) as a measure of genioglossus (GG) fatigue and overnight repetitive respiratory events in male patients with severe obstructive sleep apnea (OSA).
Methods: GG electromyography (EMG) data were collected synchronously with polysomnography (PSG). Overnight respiratory events were divided based on whether they occurred during the first or second halves of the total number of overnight respiratory events, and differences in MF in the respiratory phase were compared in the same segments.

Objective: Oral appliances (OA) are the recommended first-line option for mild-to-moderate obstructive sleep apnea (OSA)-hypopnea. However, there is a lack of evidence to compare the effectiveness of OA in different severities of OSA. The purpose of this study was to investigate the therapeutic effects of preferred OA (tongue retention devices [TRD] and mandibular advancement device [MAD]) in different severities of OSA.

Aims/objective: Our aim is to build an automatic deep learning model for OSA event detection using combined signals from the electrocardiogram (ECG) and thoracic movement signals.
Materials And Methods: We retrospectively obtained 420 cases of PSG data and extracted the signals of ECG, as well as the thoracic movement signal.
Purpose: This study aimed to investigate the association between sleep spindle metrics and executive function in individuals with obstructive sleep apnea (OSA). Furthermore, we examined the association of age and education on executive function.
Patients And Methods: A total of 230 (40.
Unlabelled: The modern practice of sleep medicine in China was introduced in the 1980s and has undergone significant development over the past few decades. The field has witnessed an increase in sleep laboratories, the publication of guidelines for the diagnosis and treatment of sleep disorders, and the establishment of several sleep medicine associations. Despite these achievements, there is still much to be done in this field.

Objective: To determine facial contour features, measured on computed tomography (CT), related to upper airway morphology in patients with obstructive sleep apnea (OSA); certain phenotype of facial abnormalities implying restriction of craniofacial skeleton and adipose tissue nimiety has predicted the value of the severity of OSA.
Materials And Method: Sixty-four male patients with OSA [apnea-hypopnea index (AHI) ≥10/h] who had upper airway CT were randomly selected to quantitatively measure indicators of facial contour and upper airway structures. Pearson correlation analyses were performed.
Concurrent screening has been proven to provide a comprehensive approach for management of congenital deafness and prevention of ototoxicity. The SLC26A4 gene is associated with late-onset hearing loss and is of great clinical concern. For much earlier detection of newborns with deafness-causing mutations in the SLC26A4 gene, the Beijing Municipal Government launched a chip for optimized genetic screening of 15 variants of 4 genes causing deafness based on a chip to screen for 9 variants of 4 genes, and 6 variants of the SLC26A4 gene have now been added.

Background: Obstructive sleep apnea (OSA) is a common sleep disorder. However, current diagnostic methods are labor-intensive and require professionally trained personnel. We aimed to develop a deep learning model using upper airway computed tomography (CT) to predict OSA and to warn the medical technician if a patient has OSA while the patient is undergoing any head and neck CT scan, even for other diseases.

This study aimed to explore the regulatory mechanisms of NR in patients with obstructive sleep apnea (OSA) during postural changes.
Methods: Healthy controls (apnea-hypopnea index < 5 events/h) and patients with OSA were recruited.
