#1
Clodagh M Ryan, Kelly Wilton, T Douglas Bradley, Hisham Alshaer
PURPOSE: Sleep apnea (SA) is highly prevalent in post-stroke patients. Due to physical disability and relative inaccessibility of polysomnography (PSG) to test for SA, patients with stroke frequently remain undiagnosed and untreated. Portable SA monitoring can facilitate at-home or in-hospital testing for SA. However, portable SA monitoring is not recommended in those with complex medical conditions, such as stroke, due to the lack of validation of portable monitoring in such patients...

PURPOSE: Few studies have investigated myofunctional therapy in patients with obstructive sleep apnea syndrome (OSAS). The objective of this study was to evaluate the effect of myofunctional therapy on continuous positive airway pressure (CPAP) adherence. METHODS: The study was registered at ClinicalTrials.gov (NCT01289405). Male patients with OSAS were randomly divided into four treatment groups: placebo, patients undergoing placebo myofunctional therapy (N = 24); myofunctional therapy, undergoing myofunctional therapy (N = 27); CPAP, undergoing treatment with CPAP (N = 27); and combined, undergoing CPAP therapy and myofunctional therapy (N = 22)...

BACKGROUND: The sawtooth sign in spirometry is associated with redundant upper airway tissue and snoring, but its predictive value for identifying obstructive sleep apnea (OSA) is disputed. We retrospectively assessed the predictive value of the spirometric sawtooth sign in terms of the odds ratio (OR) of association with a diagnosis of OSA compared to those without the sign. METHODS: Consecutive spirometry reports showing a sawtooth sign were identified from our laboratory...

PURPOSE: Cheyne-Stokes respiration (CSR) during sleep has been studied extensively in patients with chronic heart failure (CHF). Prevalence and prognostic significance of CSR during wakefulness in CHF, however, are largely unknown. METHODS: CSR during wakefulness with an apnea-hypopnea cut-off ≥5/h and moderate to severe CSR with an apnea-hypopnea cutoff ≥15/h were analyzed using polysomnographic recordings in 267 patients with stable CHF with reduced left ventricular (LV) ejection fraction at our institution...

PURPOSE: This study aimed to explore the patterns of heart rate acceleration runs and deceleration runs in patients with obstructive sleep apnea syndrome and to investigate the influence of apnea events on this pattern. METHODS: The 6-h electrocardiography results of patients who were referred for overnight polysomnography were retrospectively analyzed. The frequencies of heart rate acceleration runs and deceleration runs of different lengths were calculated for each patient and compared among patients with obstructive sleep apnea syndrome of varying degrees of severity, between patients with obstructive sleep apnea on and off continuous positive airway pressure, and between two matched groups of patients with idiopathic central sleep apnea and obstructive sleep apnea...

BACKGROUND: Numerous mathematical formulas have been developed to determine continuous positive airway pressure (CPAP) without an in-laboratory titration study. Recent studies have shown that style of CPAP mask can affect the optimal pressure requirement. However, none of the current models take mask style into account. Therefore, the goal of this study was to develop new predictive models of CPAP that take into account the style of mask interface. METHODS: Data from 200 subjects with attended CPAP titrations during overnight polysomnograms using nasal masks and 132 subjects using oronasal masks were randomized and split into either a model development or validation group...

PURPOSE: REM (rapid eye movement) sleep behavior disorder (RBD) is characterized by increased muscle tone and violent limb movements and is a usual symptom of the early stages of Parkinson's disease (PD). PD patients with RBD represent faster motor and cognitive dysfunction progression. However, there are limited studies on possible structural brain changes underpinning this disorder. METHODS: Diffusion magnetic resonance imaging (DMRI) was used to assess whether microstructural abnormalities in the brain of 23 RBD positive PD are detectable compared to 31 RBD negative PD...

PURPOSE: In this report, we examined the association between obstructive sleep apnea (OSA) and upper and lower airway inflammation based on nitric oxide (NO) measurements. METHODS: Study subjects included 51 consecutive participants. Sleep-disordered breathing was evaluated by a type 3 portable monitor and quantified by respiratory disturbance index (RDI). Airway inflammation was noninvasively analyzed by the measurement of nasally and orally exhaled NO; nasal value was presented as nasally exhaled NO minus orally exhaled NO...

PURPOSE: Excessive daytime sleepiness is the most common complaint reported in sleep clinics. We hypothesised that utilising modern media to deliver an online Epworth Sleepiness Scale, age- and gender-related differences in subjective daytime sleepiness could be assessed. METHODS: Age, gender and online Epworth Sleepiness Scale (range 0-24 points) of 39,448 subjects were recorded between January 2013 and November 2015. RESULTS: A significant trend, for males but not females, was found between age and Epworth score (p < 0...

PURPOSE: Obstructive sleep apnea (OSA) is highly associated with type 2 diabetes mellitus (DM), and treatment of OSA may have a positive impact on cardiometabolic profile. This study investigates the effects of continuous positive airway pressure (CPAP) treatment on glycemic control and cardiometabolic parameters in patients with diabetes. METHODS: Diabetic patients, who were newly diagnosed of OSA with an apnea hypopnea index (AHI) ≥15 and HbA1c ≥7%, were randomly assigned to either CPAP treatment or no treatment (control) for 3 months...

PURPOSE: The relationship between the severity of the apnea-hypopnea index (AHI) and the quality of life (QOL) in patients with obstructive sleep apnea (OSA) has been inconsistent in previous studies. This study aimed to identify the core factor associated with the QOL of suspected OSA patients and to compare the QOL of subjects with OSA and simple snoring (SS). METHODS: Two hundred eighty-five subjects who were clinically suspected to have OSA underwent nocturnal polysomnography (PSG) and completed self-report questionnaires including the World Health Organization Quality of Life Short Form (WHOQOL-BREF) and the Pittsburgh Sleep Quality Index (PSQI)...

PURPOSE: A large number of asthmatic patients, particularly females, present inadequate disease control. Depressive symptoms are reportedly common in asthma and have been related to poor disease control, but the mechanism of this association is still unclear. Poor quality sleep, frequently observed in asthmatics, is also a manifestation of depression and has been related to uncontrolled asthma. This study aimed to investigate the relationship between depressive symptoms, sleep quality, and asthma control...

PURPOSE: Chronic sleep problems can lead to difficulties for both the individual and society at large, making it important to effectively measure sleep. This study assessed the accuracy of an iPhone application (app) that could potentially be used as a simple, inexpensive means to measure sleep over an extended period of time in the home. METHODS: Twenty-five subjects from the ages of 2-14 who were undergoing overnight polysomnography (PSG) were recruited. The phone was placed on the mattress, near their pillow, and recorded data simultaneously with the PSG...
