Obesity is among the leading risk factors for obstructive sleep apnea (OSA). A reciprocal relationship between obesity and OSA has been proposed, which may be due to excessive food intake. We conducted a pilot study to test the effects of continuous positive airway pressure (CPAP) on energy intake (EI) in OSA patients using a sham-controlled crossover design. In-laboratory total daily EI was assessed after 2mo of active and sham CPAP. Four men were enrolled (age±SEM: 51.8±2.1y; body mass index: 31.5±1.5kg/m(2))...

Obesity, along with hypertrophy of the adenoids and the tonsils, represents one of the major risk factors for obstructive sleep apnea (OSA) in children. Obesity is associated with an increase in the prevalence and the severity of OSA and is a major factor in the persistence and aggravation of OSA over time. Neurocognitive dysfunction and abnormal behavior are the most important and frequent end-organ morbidities associated with OSA in children. Other deleterious consequences such as cardiovascular stress and metabolic syndrome are less common in children than in adults with OSA...

BACKGROUND: Over 300 million patients undergo surgery worldwide each year. Postoperative morbidity - particularly respiratory complications - are most frequent and severe among high-risk patients undergoing major abdominal surgery. However, standard treatments, like physiotherapy or supplemental oxygen, often fail to prevent these. Preliminary research suggests that prophylactic continuous positive airways pressure (CPAP) can reduce the risk of postoperative respiratory complications...

Resistant hypertension is defined as blood pressure that remains above 140/90 mmHg in spite of the concurrent use of three antihypertensive agents of different classes at optimal dosing, of which one should be a diuretic. Accordingly, it is not synonymous with uncontrolled hypertension. Among a variety of risk factors, obstructive sleep apnea (OSA), which is a common type of sleep-disordered breathing, has been recognized a well-established risk factor for resistant hypertension. Indeed, both European and American guidelines for the management of arterial hypertension stated that OSA is a modifiable cause of resistant hypertension...

OBJECTIVE: Obstructive sleep apnoea (OSA) is known to commonly co-exist with primary aldosteronism (PA), but it is unknown if treatment via mineralocorticoid receptor blockade or adrenalectomy (for aldosterone producing adenoma, APA), improves sleep apnoea parameters in these patients. We therefore aimed to determine if specific medical or surgical treatment of PA improves OSA, as measured by the apnoea hypopnoea index (AHI). DESIGN AND METHOD: Patients undergoing diagnostic workup for PA were recruited if they had symptoms suggestive of OSA...

OBJECTIVE: There is uncertainty over whether treatment of obstructive sleep apnea (OSA) can prevent serious cardiovascular (CV) events. DESIGN AND METHOD: SAVE (NCT00738179; ACTRN12608000409370) was designed to determine whether treatment of OSA with CPAP reduces the risk of serious CV events in patients with established CV disease. Participants were centrally randomised to CPAP treatment or usual care between 2008 and 2013,with follow-up completed late 2015 and the results will be announced in August 2016...

Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular diseases. Aldosterone was reported to be increased in patients with OSA and correlated with OSA severity. Many studies investigated the effect of continuous positive airway pressure (CPAP) therapy on plasma aldosterone concentrations (PAC) in OSA patients. The results, however, were inconsistent. In the present study, we aimed to evaluate the effects of CPAP therapy on PAC by performing a meta-analysis. Literature search was carried out in electronic databases including PubMed/Medline, Cochrane Library, Embase and Web of Science...

BACKGROUND: Continuous positive airway pressure (CPAP) in asthma patients with concomitant obstructive sleep apnea syndrome (OSAS) seems to have a favorable impact on asthma, but data are inconsistent due to methodological limitations of previous studies METHODS: Prospective, multicenter study. We examined asthma outcomes after six months of CPAP in 99 adult asthma patients (mean age 57 years) with OSAS (respiratory disturbance index ≥20). Asthma control and quality of life were assessed with the Asthma Control Questionnaire (ACQ) and the Mini Asthma Quality of Life Questionnaire (MiniAQLQ), respectively...

BACKGROUND: Patients with acute respiratory failure are at risk of deterioration during prehospital transport. Ventilatory support with continuous positive airway pressure (CPAP) can be initiated in the prehospital setting. The objective of the study is to evaluate adherence to treatment and effectiveness of CPAP as an addition to standard care. METHODS: In North Denmark Region, patients with acute respiratory failure, whom paramedics assessed as suffering from acute cardiopulmonary oedema, acute exacerbation of chronic obstructive pulmonary disease or asthma were treated with CPAP using 100 % O2 from 1 March 2014 to 3 May 2015...

PURPOSE: The aim of the study was to investigate cardiopulmonary coupling (CPC) as a tool for evaluating the efficacy of continuous positive airway pressure (CPAP) in the treatment of obstructive sleep apnea (OSA). METHOD: The medical records of patients who had undergone either standard polysomnography (PSG-only group, n = 62) or split-night CPAP titration (CPAP titration group, n = 115) due to habitual snoring or sleep apnea were analyzed. RESULT: The apnea-hypopnea index, CPC variables, and sleep stage (%) during the first 2 h of the sleep study did not differ between the PSG-only and CPAP titration groups...

Obstructive sleep apnea is a common condition, primarily caused by narrowing of the nasal and pharyngeal airway. Treatment with continuous positive airway pressure (CPAP) is considered the first line of therapy, but long-term compliance is only about 40%, often because of nasal obstruction. Any nasal obstruction can worsen CPAP compliance. Treatment of the nasal obstruction with topical nasal steroid sprays or nasal dilators has been shown to improve sleep disordered breathing. Surgical treatment of nasal obstruction, has been shown to improve sleep disordered breathing, as well as CPAP requirement and compliance with CPAP...

A 43-year-old man was referred to our tertiary sleep center for the initiation of sleep apnea treatment. A prior diagnostic overnight polysomnography (Fig 1) had revealed an apnea-hypopnea index (AHI) of 22/h of sleep. The apneas were predominantly central (central AHI, 18.2/h; obstructive AHI, 3.8/h), more pronounced in the supine position (AHI supine, 36.6/h; AHI nonsupine, 11/h) and during non-rapid eye movement (non-REM) sleep (REM, 15.8/h; non-REM, 23.5/h). A continuous positive airway pressure (CPAP) trial in an outpatient setting had failed, as the fixed CPAP of 11 cm H2O was not tolerated by the patient because of a feeling of lightheadedness when wearing the mask...

The obstructive sleep apnea (OSA) is a mortality risk factor of the cardiovascular system diseases. One of the elements of this relationship is the occurrence of nocturnal cardiac arrhythmias. The arrhytmias in question are resistant to drug therapy so it is suggested to consider electrotherapy. However, the coexistence of OSA and thus recurrent episodes of nocturnal hypoxia, may have significant impact on the diagnosis and the treatment applied as shown in the following cases. In some cases, the decision of electrotherapy should be preceded by the use of therapy with continuous positive airway pressure (CPAP)...

OBJECTIVES: Inhaled nitric oxide (iNO) is effective in conjunction with tracheal intubation (TI) and mechanical ventilation (MV) for treating arterial pulmonary hypertension and hypoxemic respiratory failure (HRF) in near-term and term newborns. Non-invasive respiratory support with nasal continuous positive airway pressure (CPAP) is increasingly used to avoid morbidity associated with TI and MV, yet the effectiveness of iNO delivery via nasal CPAP remains unknown. To evaluate the effectiveness of iNO delivered via the bubble nasal CPAP system in term and preterm newborns with HRF...

STUDY OBJECTIVES: Posttraumatic stress disorder (PTSD) is common among veterans of the military, with sleep disturbance as a hallmark manifestation. A growing body of research has suggested a link between obstructive sleep apnea and PTSD, potentially due to obstructive sleep apnea (OSA) related sleep disruption, or via other mechanisms. We examined the hypothesis that treatment of OSA with positive airway pressure would reduce PTSD symptoms over 6 months. METHODS: A prospective study of Veterans with confirmed PTSD and new diagnosis of OSA not yet using PAP therapy were recruited from a Veteran's Affairs sleep medicine clinic...

BACKGROUND: Clinical presentation phenotypes of obstructive sleep apnoea (OSA) and their association with comorbidity as well as impact on adherence to continuous positive airway pressure (CPAP) treatment have not been established. METHODS: A prospective follow-up cohort of adult patients with OSA (apnoea-hypopnoea index (AHI) of ≥5/h) from 17 European countries and Israel (n = 6,555) was divided into four clinical presentation phenotypes based on daytime symptoms labelled as excessive daytime sleepiness ("EDS") and nocturnal sleep problems other than OSA (labelled as "insomnia"): 1) EDS (daytime+/nighttime-), 2) EDS/insomnia (daytime+/nighttime+), 3) non-EDS/non-insomnia (daytime-/nighttime-), 4) and insomnia (daytime-/nighttime+) phenotype...

BACKGROUND AND AIMS: Obstructive sleep apnea (OSA) is characterized by intermittent airway obstruction and systemic hypoxia during sleep, which can contribute to an increase in reactive oxygen species, vascular remodeling, vasoconstriction and ultimately cardiovascular disease. Continuous positive airway pressure (CPAP) is a clinical therapy that maintains airway patency and mitigates several symptoms of OSA. However, it is currently unknown whether CPAP therapy also reduces the overall inflammatory potential in the circulation; to address this in an unbiased manner, we applied a novel endothelial biosensor approach, the serum cumulative inflammatory potential (SCIP) assay...

OBJECTIVE: In obstructive sleep apnea (OSA), while both hypothyroidism and hyperthyroidism have been studied, the occurrence of non-thyroidal illness syndrome (NTIS) (normal thyroid stimulating hormone [TSH] with low triiodotironine) has not been investigated. We explored the occurrence of NTIS in patients with moderate to severe OSA and its relationship to the severity of nocturnal respiratory disorders. We also studied the occurrence of subclinical hypothyroidism (SH, ie, high TSH with normal thyroxine) in OSA and changes in circulating TSH, free triiodotironine (fT3) and free thyroxine (fT4) after CPAP treatment...

PURPOSE: This study aimed to test the hypothesis that erectile dysfunction (ED) is common in men with obstructive sleep apnea (OSA). We also assessed the efficacy of continuous positive airway pressure (CPAP) treatment for ED and sex hormone levels in patients with severe OSA and ED. METHODS: A total of 153 OSA patients and 60 healthy controls were enrolled in this study. The International Index of Erectile Dysfunction-5 (IIEF-5) score was obtained, and blood samples were collected for analysis of sex hormones after polysomnography...
