BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is related to arterial hypertension. In the present study, we test the hypothesis that patients with severe OSAS have excessive apnea induced blood pressure (BP). METHODS: We investigated 97 patients with an apnea/hypopnea index (AHI) greater than 30. Systolic BP (SBP) was continuously determined by using the pulse transit time (PTT). Apnea/hypopnea induced nocturnal BP fluctuations (NBPFs) were detected and showed phenomena of continuous increases of the SBP baseline...

PURPOSE: Hypoxic insults occurring during the perinatal period remain the leading cause of permanent brain impairment. Severe cognitive and motor dysfunction, as seen in cerebral palsy, will occur in 4-10% of post-hypoxic newborns. Subtle cognitive impairment, apparent in disorders of minimal brain dysfunction will occur in > 3 million post-hypoxic newborns. Analyses of post-hypoxic rodent brains reveal reduced extracellular levels of dopamine, a key neurotransmitter of vigilance, execute function, and behavior...

PURPOSE: We examined factors, including the severity of obstructive sleep apnea (OSA), that were associated with depressive symptoms and excessive daytime sleepiness in OSA patients. METHODS: We retrospectively reviewed data of 1203 subjects (861 men, mean age 48.2 years) who completed self-reported questionnaires and underwent polysomnography between September 2005 and May 2016 at the Center for Sleep and Chronobiology at Seoul National University Hospital. We compared scores on the Beck Depression Inventory (BDI) and Epworth sleepiness scale (ESS) between OSA and control groups...

PURPOSE: Home sleep testing devices are being widely used in diagnosis/screening for obstructive sleep apnea (OSA). We examined differences in OSA metrics obtained from two devices with divergent home monitoring strategies, the Apnea Risk Evaluation System (ARES™, multiple signals plus forehead reflectance oximetry) and the Nonin WristOx2™ (single channel finger transmission pulse oximeter), compared to differences from night-night variability of OSA. METHODS: One hundred fifty-two male/26 female subjects (BMI = 30...

PURPOSE: This study aimed to delineate the clinical and polysomnography (PSG) characteristics of sleep disorders in children with excessive daytime sleepiness (EDS). METHODS: Between February 2002 and June 2015, 622 pediatric patients with EDS were evaluated with overnight PSG and the Multiple Sleep Latency Test at the Samsung Medical Center. The medical records; questionnaire responses about depression, sleepiness, sleep habits; and sleep study data of 133 patients without obstructive sleep apnea (OSA) were reviewed retrospectively...

BACKGROUND: A small percentage of adult patients with severe obstructive sleep apnea (OSA) has been recognized to be extraordinarily difficult to treat with conventional continuous or Bi-level positive airway pressure (together referred to as PAP) therapy. AIM AND OBJECTIVES: The aim of this study was to determine polysomnographic (PSG) characteristics, which may help predict the requirement for advanced therapeutic options for OSA. METHODS: Consecutive patients who underwent PAP titration at our sleep laboratory over a 2-year period were included...

PURPOSE: Recent studies found that the non-contact screening device SleepMinder (ResMed Sensor Technologies, Dublin, Ireland) detects sleep-disordered breathing (SDB) with high diagnostic accuracy in cohorts suspected of this disorder. However, it was reported that in patients with periodic limb movement in sleep (PLMS), this non-contact device overestimates the apnea-hypopnea index (AHI). We aimed to overcome this limitation by introducing the novel sleep disorder index (SDI) which is sum of the AHI and the period limb movement index (PLMI)...

Obstructive sleep apnea (OSA) has many serious consequences, and one of these may be the exacerbation of type 2 diabetes mellitus (T2DM). Reports on the effect of continuous positive airway pressure (CPAP) on glucose metabolism in people with T2DM and OSA are conflicting. Therefore, the purpose of this review was to examine the effect of CPAP treatment on glucose metabolism by synthesizing findings from randomized controlled trials. The PRISMA review protocol was developed and registered in PROSPERO. A systematic search of PubMed, CINAHL, Embase, Web of Science, PsycInfo, and Cochrane was conducted from inception to March 2017...

PURPOSE: Although many studies have investigated the clinical importance of sleep apnea on rapid eye movement (REM) and non-REM (NREM) sleep, the relationship between behavioral performance and apneic events during different sleep phases remains unclear. In the present study, we sought to investigate the effect of sleep phase fragmentation due to sleep-disordered breathing (SDB) during REM and NREM on the vigilance and sustainability of attention based on psychomotor vigilance task (PVT) performance...

PURPOSE: Arousal plays an important protective role against life-threatening events by terminating the apneic events. However, arousal might also be considered as a contributor to obstructive sleep apnea (OSA) pathogenesis since ventilatory overshoot due to arousal leads to irregular breathing. Patients with OSA who have greater upper airway compensation, expressed by relatively high proportion of apneic events without arousal, could have less adverse events or consequences. Thus, our hypothesis was that the proportion of apneic events with or without arousal affects daytime systemic blood pressure and nocturnal sympathetic activity...

PURPOSE: Portable respiratory monitor (PRM) has been proposed for pre-diagnosis of obstructive sleep apnea syndrome (OSAS). However, discrepant physiological signal combinations were rarely studied for diagnostic assessment of OSAS. This study was designed to evaluate combination modes of key physiological signals collected by portable sensor modules for OSAS screening in comparison with polysomnography (PSG). METHODS: People with suspected OSAS were submitted to PRM at a sleep laboratory monitoring concurrently with PSG...

PURPOSE: Obstructive sleep apnea (OSA) has been linked to higher rates of perioperative complications. Practice guidelines recommend minimizing opioids in this cohort to reduce complications. However, a paucity of evidence exists relating different levels of opioid prescription to perioperative complications. Our aim was to investigate if different levels of opioid prescription are related to perioperative complication risk in patients with OSA. METHODS: A total of 107,610 OSA patients undergoing total knee or hip arthroplasty between 2006 and 2013 were identified in a nationwide database and divided into subgroups according to the amount of opioids prescribed...

PURPOSE: Pulmonary surfactant (PS) plays roles in promoting the removal of the liquid, host defense, and immune regulation in the tracheal, bronchial, and alveoli epithelium. PS protein expression level can be regulated by oxygen levels and related free radicals. Obstructive sleep apnea (OSA) is featured with oxygen free radical production for damaging epithelial tissues and thus may affect PS production. The study was to explore the relationship between PS protein and OSA severity. METHODS: We collected serum and bronchoalveolar lavage fluid (BALF) samples from 35 OSA patients and 22 healthy subjects...

BACKGROUND: With increasing use of atypical antipsychotic (AAP) agents, the concern has been raised about the association between AAP agents and medical complications. Obstructive sleep apnea (OSA) is a common breathing disorder that adversely affects health and quality of life. Because the major risk factors for OSA are weight gain and obesity by altering the upper airway anatomy, an association between AAP and development of OSA is predictable. However, we hypothesized that AAP may promote OSA not only by weight gain but also because of its potential effects on upper airway muscle function...

REVIEW
Mohamad Ammar Albdewi, Giuseppe Liistro, Riëm El Tahry
Sleep-disordered breathing (SDB) is relatively common in general population as well as in patients with neuromuscular disease. SDB comprises a wide spectrum of disorders varying from simple snoring to complete closure of the upper airway as seen in obstructive sleep apnoea (OSA). It includes also other disorders like prolonged hypoxemia, hypoventilation, and central sleep apnoea (CSA). Neuromuscular diseases (NMD) form a group of disorders that can cause significant reduction in the quality and span of life...
