Introduction: Sleep-disordered breathing (SDB) is common in children with PWS. In the current study, we aimed to evaluate the severity of SDB in patients with PWS using polysomnography (PSG), and assess the effect of the underlying genetic mechanism on PSG parameters.
Methods: Children with PWS, referred to our sleep laboratory between March 2016 and January 2020 were enrolled. PSG parameters, demographic data, body mass index (BMI), and symptoms related to SDB were recorded. The effect of non-invasive ventilation strategies and the outcome of therapy on PSG parameters were evaluated.
Results: In our study, 64.5% of the patients had severe sleep apnea syndrome (total apnea hypopnea index (AHI) ≥10 events/hour). 22.6% had significantly high (>5 events/hour) central sleep apnea. Patients with a deletion had significantly lower initial and mean SaO, longer sleep time SaO under 90%, oxygen desaturation % and total AHI when compared to those with uniparental disomy. PSG parameters were similar between patients who did or didn't receive growth hormone treatment.
Conclusion: The majority of the PWS patients had severe sleep apnea syndrome characterized mainly by hypopneas which were accompanied by central apneas. There was a more severe impact on oxygen parameters and total AHI in patients with deletions.
Objective/background: Obstructive sleep apnea (OSA) is a common disease, which poses a significant health threat. Initial diagnostics with polygraphy or polysomnography are time consuming and expensive. Therefore, there is an unmet medical need for simplification, especially to exclude healthy patients from elaborate and unnecessary diagnostics.
Objectives: The relationship between obstructive sleep apnea (OSA) and hearing loss (HL) remains uncertain. This study aimed to investigate the relationship between OSA and HL, and to identify which factors play a key role.
Methods: A retrospective review was conducted of 90 subjects diagnosed with OSA.

Objective: To evaluate the instant impact of transcranial alternating current stimulation (tACS) on sleep brain oscillations.
Methods: Thirty-six healthy subjects were randomly assigned to receive tACS and sham stimulation in a crossover design separated by a one-week washout period. After stimulation, a 2-h nap polysomnography (PSG) was performed to obtain Electroencephalogram (EEG) data and objective sleep variables, and self-reported subjective sleep parameters were collected at the end of the nap.
Background: Low-dose morphine may be prescribed to reduce chronic breathlessness in chronic obstructive pulmonary disease (COPD). Recent subjective findings suggest morphine may influence breathlessness through sleep-related mechanisms. However, concerns exist regarding opioid safety in COPD.
Study Objectives: Obstructive sleep apnea (OSA) is a common disorder in the pediatric population, primarily diagnosed through polysomnography (PSG). 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.
