Can Wang, Jianxin Peng, Lijuan Song, Xiaowen Zhang
Obstructive sleep apnea hypopnea syndrome (OSAHS) is a serious respiratory disorder. Snoring is the most intuitively characteristic symptom of OSAHS. Recently, many studies have attempted to develop snore analysis technology for diagnosing OSAHS. The preliminary and essential step in such diagnosis is to automatically segment snoring sounds from original sleep sounds. This study presents an automatic snoring detection algorithm that detects potential snoring episodes using an adaptive effective-value threshold method, linear and nonlinear feature extraction using maximum power ratio, sum of positive/negative amplitudes, 500 Hz power ratio, spectral entropy (SE) and sample entropy (SampEn), and automatic snore/nonsnore classification using a support vector machine...

REVIEW
Patricia Tung Md, Elad Anter Md
Atrial fibrillation (AF) is the most common cardiac arrhythmia and shares many of the same risk factors as another common clinical condition, sleep apnea. The estimated prevalence of sleep apnea has increased over the past decade, and reflects a parallel increase in the most prominent risk factors of obesity and overweight. Both obstructive and central sleep apnea have been associated with AF in multiple studies, with the risk of AF increasing 2-4-fold compared to those without sleep breathing disorder. Continuous positive airway pressure (CPAP) has been shown to reduce the rate of AF recurrence following catheter ablation in patients with sleep apnea...

BACKGROUND: Sleep-disordered breathing, predominantly obstructive sleep apnea (OSA), is highly prevalent in patients with hypertension. OSA may underlie the progression to resistant hypertension, partly due to increased activation of the sympathetic nervous system. This analysis of patients with and without OSA evaluated the blood pressure (BP)-lowering effect of sympathetic modulation by renal denervation (RDN) in a real-world setting. METHODS: The Global SYMPLICITY Registry (NCT01534299) is a prospective, open-label, multicenter registry conducted worldwide to evaluate the safety and effectiveness of RDN in patients with uncontrolled hypertension...

BACKGROUND: Obstructive sleep apnea (OSA) is strongly correlated with an increased risk of systemic hypertension. However, the link between systemic hypertension and nocturnal apneas remains incompletely understood. Animal studies suggest an implication of the endothelin system. The aim of the present study is to determine if endogenous endothelin plays a role in the increase in blood pressure observed during hypoxic episodes in OSA patients, in addition to peripheral chemoreflex and neural sympathetic activation...

BACKGROUND: Perceived Health Related Quality of Life (HRQoL) is impaired in obstructive sleep apnea (OSA). This study examines changes in HRQoL aspects occurring immediately after CPAP titration. Furthermore, we analyzed variations in each gender and in patients undergoing home or laboratory-based CPAP titration pathways. METHODS: Twohundredfive outpatients (151 M) (56.7 ± 10.3 years) were evaluated, before first visit and nocturnal diagnostic examination (T0), and the morning after CPAP titration (T1)...

The incidence of cardiovascular disease and mortality rates are high among patients with left ventricular hypertrophy (LVH). Obstructive sleep apnea (OSA) has been reported to increase left ventricular mass (LVM) and cause LVH. The prevalence of hypertension, a major cause of increased LVM, is high in OSA; however, it is still unknown whether OSA is an independent factor that increases LVM in addition to triggering LVH. This study investigated out-of-office blood pressure (BP) via ambulatory BP monitoring (ABPM) in patients with OSA diagnosed by polysomnography (PSG) and sought to determine the effects of OSA and hypertension on LVM...

Caffeine is a methylxanthine that is widely used to treat apnea of prematurity (AOP). In preterm infants, caffeine reduces the duration of respiratory support, improves survival rates and lowers the incidence of cerebral palsy and cognitive delay. There is, however, little evidence relating to the immediate and long-term effects of caffeine on brain development, especially at the cellular and molecular levels. Experimental data are conflicting, with studies showing that caffeine can have either adverse or benefical effects in the developing brain...

BACKGROUND: Obesity worsens asthma control partly through enhanced airway neutrophilia, altered lung mechanics and comorbidities, including obstructive sleep apnea syndrome, gastroesophageal reflux disease and depression. Although controversial, obesity may also cause poorer outcomes in acute asthma. IL-17 is associated with neutrophilic inflammation, steroid resistance and severe asthma, but its importance in the association between asthma and obesity is unknown. OBJECTIVE: To investigate the role of IL-17 in obese asthma in both acute and stable settings...

BACKGROUND: Non-anesthesia administered propofol (NAAP) has been shown to be a safe and effective method of sedation for patients undergoing gastrointestinal endoscopy. Bariatric surgery patients are potentially at a higher risk for sedation-related complications due to co-morbidities including obstructive sleep apnea. The outcomes of NAAP in bariatric patients have not been previously reported. METHODS: In this retrospective cohort study, severely obese patients undergoing pre-surgical outpatient esophagogastroduodenoscopy (EGD) were compared to non-obese control patients (BMI ≤ 25 kg/m(2)) undergoing diagnostic EGD at our institution from March 2011-September 2015 using our endoscopy database...

A Steffen, L Maibücher, I R König
BACKGROUND: When considering supine position and REM dependence, many studies refer to the traditional definition in which obstructive sleep apnea (OSA) severity is at least doubled in the corresponding position/sleep stage (Cartwright index). The lack of consideration of the time spent in that particular sleep situation can lead to clinical bias. PATIENTS AND METHODS: Two cohorts of patients with at least moderate OSA were analyzed retrospectively for anthropometric associations and correlations with OSA severity...

BACKGROUND: The nocturnal intermittent hypoxia caused by obstructive sleep apnea syndrome (OSAS) can provoke the sympathetic nervous activity (SNA). Salivary alpha-amylase (sAA) is a sensitive, non-invasive biomarker for reflecting the SNA, and a useful marker for pediatric OSAS subjects. Adenotonsillar hypertrophy (ATH) is the most commonly identified risk factor in OSAS childhood, therefore, several studies showed that the adenotonsillectomy (T&A) may alleviate nocturnal enuresis (NE) in children with OSAS...

BACKGROUND: Expiratory pressure relief continuous positive airway pressure (pressure relief CPAP; C-Flex™) causes increases in inspiratory duty cycle and shortening of expiratory time. It has been suggested that these changes are caused by an increase in work of breathing. OBJECTIVES: We studied the effects of C-Flex on work of breathing and intrinsic positive end-expiratory pressure as compared to fixed CPAP. METHODS: Work of breathing was analyzed in 24 patients with obstructive sleep apnea during treatment with fixed CPAP and C-Flex with 3 different pressure relief settings in a randomized order during rapid-eye-movement (REM) and non-REM sleep...
