The purpose of this study was to evaluate the prevalence and assess the response to nasal automatic positive airway pressure (APAP) therapy of less typical symptoms in patients diagnosed with obstructive sleep apnea (OSA), like fatigue, gasping, nocturia, nocturnal sweating, morning headaches, heartburn, and erectile dysfunction. ⋯ The findings suggest that APAP therapy is effective in controlling the majority of OSA symptoms beyond sleepiness and snoring.

Comparative Study Controlled Clinical Trial
Effects of continuous positive airway pressure on blood pressure and daytime sleepiness in obstructive sleep apnea patients with coronary heart diseases under optimal medications.
Continuous positive airway pressure (CPAP) is an effective therapy for obstructive sleep apnea (OSA). However, for patients who already have OSA and coronary heart diseases (CHD) with optimal medications, whether CPAP can reduce the blood pressure (BP) is not clear. This is a controlled study to evaluate the effects of CPAP on BP in Chinese cohorts with CHD under optimal medications. ⋯ CPAP treatment for 1 month was associated with significant reduction in diastolic BP and improvement in ESS score. For patients with moderate to severe OSA and CHD under optimal medications, CPAP treatment leads to effective reduction in diastolic blood pressure and improvement in daytime sleepiness.

Comparative Study
Prevalence, clinical features, and CPAP adherence in REM-related sleep-disordered breathing: a cross-sectional analysis of a large clinical population.
Due to inconsistent definitions used in the literature, the prevalence of rapid eye movement (REM)-related sleep-disordered breathing (SDB) has been quite variable and its clinical significance remains unclear. This study aimed to compare the prevalence of and clinical characteristics between various criteria for defining REM-related SDB. We also investigated how frequently CPAP therapy was recommended in patients with REM-related SDB and if they had lower CPAP adherence compared to non-stage-specific SDB. ⋯ Regardless of how REM-related SDB is defined, it was highly prevalent in our large clinical cohort. Compared to non-stage-specific OSA, these patients were equally hypersomnolent and adherent to CPAP therapy despite having overall significantly milder OSA. Further research is needed to better establish whether these patients will derive any benefit from long-term CPAP therapy.

This study aimed to evaluate the sleep quality and impact of thoracentesis on sleep in patients with a large pleural effusion. ⋯ Patients with large pleural effusion have poor subjective and objective sleep quality that improves after thoracentesis.

Obstructive sleep apnea (OSA) in children is associated with obesity, insulin resistance, and elevated baseline inflammation as measured by high-sensitivity C-reactive protein (hsCRP). Our goal was to evaluate whether inflammation increases overnight among children suspected of having OSA and to determine whether worsened inflammation is associated with the degree of OSA severity, obesity, and/or insulin resistance. ⋯ Among children being evaluated for OSA, degree of insulin resistance may be an important determinant of increased systemic inflammation overnight. Sleep study markers did not correlate with ΔhsCRP, leaving uncertain the role of OSA in increasing inflammation overnight. Further studies are needed to explore these associations and their potential mechanisms.
