INTRODUCTION: Night Continuous Saturometry (CSO2) is used in Neonatal Units to detect events of hypoxemia in Newborns (NB) with apnea episodes. Polygraphy (PG) has a larger number of measuring channels. Our goal was to evaluate the diagnostic performance of CSO2 compared to Polygra phy in NB with suspected sleep apneas. PATIENTS AND METHOD: Results of CSO2 and PG performed simultaneously in RN with suspected apneas were retrospectively analyzed over a three-year period...

Central alveolar hypoventilation is rarely encountered. This case report describes a young woman who was recently diagnosed with hypertension and ischemic heart disease. She presented to the emergency room with hypercapnic respiratory failure, for which she was mechanically ventilated. This was preceded by an acute upper respiratory tract infection. She was initially suspected to have Guillain-Barré syndrome, but further investigations ruled out neuromuscular or autoimmune disorders. Sleep-related hypoventilation was suspected after she experienced recurrent apneas at night that resulted in re-intubation...

Importance: Obstructive sleep apnea (OSA) is the most common clinically significant breathing abnormality during sleep. It is highly prevalent among patients with atrial fibrillation (AF), and it promotes arrhythmogenesis and impairs treatment efficacy. Observations: The prevalence of OSA ranges from 3% to 49% in population-based studies and from 21% to 74% in patients with AF. Diagnosis and treatment of OSA in patients with AF requires a close interdisciplinary collaboration between electrophysiologists, cardiologists, and sleep specialists...

OBJECTIVES: Hypoglossal nerve stimulation (HNS) therapy is an emerging surgical treatment for select patients with obstructive sleep apnea (OSA). This study aims to compare outcomes in patients with moderate to severe OSA who underwent HNS surgery (Inspire Medical Systems) and those who underwent traditional airway reconstructive surgery, specifically uvulopalatopharyngoplasty (UPPP). METHODS: Patients who underwent HNS implantation (n = 20), all with moderate to severe OSA, inability to adhere to positive pressure therapy, and compliant with previously published inclusion criteria, were compared to a historical cohort that were intolerant of CPAP with similar inclusion criteria who all underwent UPPP (n = 20) with some also undergoing additional procedures such as septoplasty/turbinate reduction...

Sleep studies conducted at an altitude that is different from the home altitude can yield misleading results regarding the severity of obstructive sleep apnea (OSA). The objective of the present study was to determine the sleep characteristics of a patient undergoing polysomnography (PSG) in three Colombian cities at different altitudes (Bogotá, at 2,640 m above sea level [ASL]; Bucaramanga, at 959 m ASL; and Santa Marta, at 15 m ASL). The patient was an obese man with diabetes and suspected OSA. All PSG recordings were scored and interpreted in accordance with American Academy of Sleep Medicine criteria...

MOTIVATION: Obstructive sleep apnea (OSA) can impair cerebral vasoreactivity and is associated with an increased risk of cerebrovascular disease. Unfortunately, an easy-to-use, non-invasive, portable monitor of cerebral vasoreactivity does not exist. Therefore, we have evaluated the use of near-infrared diffuse correlation spectroscopy to measure the microvascular cerebral blood flow (CBF) response to a mild head-of-bed position change as a biomarker for the evaluation of cerebral vasoreactivity alteration due to chronic OSA...

OBJECTIVE: To evaluate the relationship between the hyoid-related cephalometric measurements and the apnea-hypopnea index (AHI) in patients diagnosed with obstructive sleep apnea (OSA). METHODS: A total of 56 subjects were evaluated by lateral cephalometric radiography and polysomnography (PSG). The OSA diagnosis was made according to the patients' AHI. Included were 13 primary snoring, 16 mild OSA, 10 moderate OSA, and 17 severe OSA. C3-hyoid distance and mentum-hyoid distance were measured on lateral cephalogram...

Studies have reported an association between obstructive sleep apnea (OSA) and cardiovascular disease (CVD) morbidity and mortality. Proposed mechanisms include endothelial dysfunction and atherosclerosis. We aimed to investigate the associations of OSA with endothelial dysfunction and subclinical atherosclerotic coronary artery disease (CAD), and assess the impact of race on these associations. We used data from the Heart Strategies Concentrating on Risk Evaluation (Heart SCORE) study, a community-based prospective cohort with approximately equal representation of black and white participants...

Sleep-disordered breathing (SDB), encompassing both obstructive and central sleep apnea, is prevalent in at least 50% of stroke patients. Small studies have shown vast improvements in post-stroke functional recovery outcomes after the treatment of SDB by continuous positive airway pressure. However, compliance to this therapy is very poor in this complex patient group. There are alternative therapy options for SDB that may be more amenable for use in at least some post-stroke patients, including mandibular advancement, supine avoidance, and oxygen therapy...

OBJECTIVE: To analyze metabolic and hormonal disorders resulting from the association between obesity and obstructive sleep apnea (OSA) syndrome that predispose to cardiovascular diseases and investigate the clinical benefits obtained from treatment approaches for both conditions. METHODS: A literature review between 1997 and 2017 was conducted in the PubMed search database. RESULTS: Obesity is the most important risk factor for OSA, and the progressive increase in its prevalence also affects OSA incidence...

Study Objectives: Sleep quality is poor among patients with COPD, and studies show sleep disturbance is associated with low overall quality of life in this population. We evaluated the impact of patient-reported sleep quality and sleep apnea risk on disease-specific and overall quality of life within COPD patients enrolled in the SPIROMICS study, after accounting for demographics and COPD disease severity. Methods: Baseline data from 1,341 participants [892 mild/moderate COPD (FEV1≥50% predicted); 449 severe COPD (FEV1<50%)], were used to perform three nested (blocks) regression models to predict quality of life (Short Form-12 mental and physical components and St...

Background: Sleep apnea (SA) is common and has prognostic significance among broad groups of patients with heart failure (HF). Among persons living with HIV (PLHIV), both SA and HF are reported. However, there are no data characterizing the presence, associations and prognostic significance of SA among PLHIV with HF. Methods: We conducted a single center study of PLHIV admitted with HFrEF (LVEF of <50%) and analyzed the relationship of SA with 30-day HF hospital readmission rate, cardiovascular (CV) and all-cause mortality...

BACKGROUND: Periodic leg movements during sleep (PLMS) have been associated with an increased risk for cardiovascular diseases and there is a high prevalence of PLMS found in patients with obstructive sleep apnea syndrome (OSAS). We evaluated patients with transient ischemic attack (TIA) for PLMS and respiratory related leg movements (RRLM), versus a control group without TIA. METHODS: Twenty-five patients with TIA and 34 patients with no vascular diagnosis were referred for polysomnography...

BACKGROUND: Patients with obstructive sleep apnea (OSA) experience intermittent hypoxia, hypercarbia, and sympathetic activation during sleep, which increases risk for paroxysmal atrial fibrillation and other cardiac arrhythmias. Whether patients with OSA experience increased episodes of atrial fibrillation after cardiac surgery is unclear. We examined whether patients at increased risk for OSA, assessed by the STOP-BANG (snoring, tired during the day, observed stop breathing during sleep, high blood pressure, body mass index more than 35 kg/m, age more than 50 years, neck circumference more than 40 cm, and male gender) questionnaire, had a higher incidence of new-onset postoperative atrial fibrillation after cardiac surgery...

The aim of the present study was to summarize the risk factors for bruxism that were identified by a systematic search of the literature published between 2007 and 2016. Depending on the size of the odds ratios (ORs) and the lower limit of the 95% confidence intervals indicated by the reports, four risk categories were differentiated. Among others, emotional stress, consumption of tobacco, alcohol, or coffee, sleep apnea syndrome, and anxiety disorders were recognized as important factors among adults. In children and adolescents, apart from distress, behavioral abnormalities and sleep disturbances predominated...

Sleepiness and cardiovascular disease share common molecular pathways; thus, metabolic risk factors for sleepiness may also predict cardiovascular disease risk. Daytime sleepiness predicts mortality and cardiovascular disease, although the mechanism is unidentified. This study explored the associations between subjective sleepiness and metabolite concentrations in human blood plasma within the oxidative and inflammatory pathways, in order to identify mechanisms that may contribute to sleepiness and cardiovascular disease risk...

BACKGROUND: Although excessive daytime sleepiness (EDS) is a common symptom of obstructive sleep apnea (OSA), and both EDS and OSA have separately been associated with increased risk of cardiovascular disease (CVD), their joint association with CVD risk is unknown. METHODS: Among 3874 Sleep Heart Health Study (SHHS) participants without prevalent CVD, moderate to severe OSA was defined by an apnea hypopnea index (AHI) ≥ 15 on an in-home polysomnography. EDS was defined as an Epworth Sleepiness Scale score ≥11...

Continuous positive airway pressure (CPAP) is being increasingly used in children of all age ranges. The limited number of commercially available masks especially in infants and young children may complicate its use and compliance. In this report, we describe our experience with the use of the Optiflow™ (Fisher and Paykel Healthcare) Nasal Cannula attached to a regular CPAP device in the setting of chronic CPAP use. This interface consists of a nasal cannula and was originally designed for the delivery of high-flow oxygen therapy...
