Introduction: Obstructive Sleep Apnea (OSA) has been associated with an elevated risk of cardiac arrhythmia. Continuous positive airway pressure (CPAP) is the selected treatment for moderate to severe OSA and could improve arrhythmias in the long term. However, the acute effect of CPAP has not been studied in detail. Methods: We conducted a prospective study with 25 patients with moderate to severe OSA diagnosed by home respiratory polygraphy (RP) and arrhythmia and/or pauses in 24-hour Holter ECG...

According to recent reports, sleep disorders affect 30% of the adult population and 5-10% of children. Obstructive Sleep Apnea Hypopnea Syndrome (OSA) has a considerable epidemiological impact and demand for consultation is growing in our community. Therefore, it is necessary to know the principles of interpretation of diagnostic methods. A suspicion of OSA requires confirmation. According to the guidelines of the Argentine Association of Respiratory Medicine, polysomnography (PSG) is the gold standard for OSA diagnosis, while home sleep testing (HST) can be accepted as a comparatively effective method depending on the clinical situation of the patient...

Introduction: Existing sleep questionnaires to assess sleep behaviors may not be sensitive in determining the unique sleep challenges faced by elite athletes. The purpose of the current study was to develop and validate the Athlete Sleep Behavior Questionnaire (ASBQ) to be used as a practical tool for support staff working with elite athletes. Methods: 564 participants (242 athletes, 322 non-athletes) completed the 18-item ASBQ and three previously validated questionnaires; the Sleep Hygiene Index (SHI), the Epworth Sleepiness Scale (ESS) and the Pittsburgh Sleep Quality Index (PSQI)...

Narcolepsy type 1 (NT1) is a chronic sleep disorder, characterized by excessive daytime sleepiness, cataplexy and fragmented nocturnal sleep. It is caused by a hypocretin deficiency due to a significant reduction of the neurons producing it. In the last years, it has been postulated that an autoimmune mechanism would be responsible for the destruction of these neurons in those genetically predisposed patients. The increased incidence of narcolepsy after the pandemic H1N1 influenza vaccination campaign in 2009-2010 is known...

Background: Attended polysomnography (PSG) is the standard diagnostic test for sleep apnea (SA). However, due to internight variability in SA, a single night PSG may not accurately reflect the true severity of SA. Although internight variability is a well-known phenomenon, its root causes have not been fully elucidated. The objective of this study was to determine factors associated with internight variability in the apnea-hypopnea index (AHI) and its magnitude in the home environment...

Stroke is an example of neurological diseases that can commonly drives Excessive Daytime Sleepiness (EDS). Extensive strokes with brain edema can leave a brain herniation and coma. Other causes of EDS after stroke are strategic lesions at Thalamus and brainstein. A 56-year-old man, right handed, with hypertension and hypercholesterolemia was admitted at Emergency Room due to 5 days onset of EDS, memory impairment, and left-sided weakness. A brain magnetic resonance imaging showed paramedian thalamic hyperintensity with rostral midbrain hyperintensity extending along the pial surface of the interpeduncular fossa...

Purpose: Athletes involved in team sports may be subject to varying degrees of sleep deprivation either before or after training and competition. Despite the belief among athletes and coaches of the importance of adequate sleep for ensuing performance, the effect of sleep loss on team-sport anaerobic performance remains unclear. There is conflicting evidence in the scientific literature as to the impact of acute sleep deprivation and caffeine supplementation on anaerobic performance indices...

The integrative care model is rooted in a biopsychosocial approach. Integrative is a term which refers to increasing the harmony and coherence of your whole being, and integrative care is therefore focused on the person, not on either the disease or a therapy. It is provided collaboratively by a health team comprising physicians, psychologists, physiotherapists, acupuncturists, and meditation, nutrition, and floral therapy. Previous studies have demonstrated that interventions based on the integrative care model improved womens lifestyle and quality of life...

Obstructive Sleep Apnea Syndrome (OSA) is a multifactorial disease that highly alters a persons quality of life. It is characterized by the repeated interruption of breathing during sleep, due to an obstruction or the collapse of the upper airways. Since it is a multifactorial etiological disorder, it requires a thorough diagnosis and treatment with an interdisciplinary team, which comprises several professionals such as a surgical dentist, phonoaudiologist, otorhinolaryngologist, sleep doctor, neurologist and physiotherapist...

Introduction: REM sleep deprivation increases unstimulated erections in rats, and total sleep deprivation increases erections during audiovisual sexual stimulation in men, but the effects of sleep problems on human unstimulated sexual arousal are unknown. Objective: We examined the associations of subjective sleep quality with unstimulated sexual arousal, satisfaction with sex life, and sexual frequency and desire over the past month. Methods: 275 Portuguese (169 women) reported their anxiety, sexual arousal and sexual desire during a resting state, and completed the Pittsburgh Sleep Quality Index, the sexual satisfaction subscale of the LiSat scale, the Desire dimensions of the Female Sexual Function Index (women only) and International Index of Erectile Function (men only)...

Introduction: Reduced sleep to increase work hours is common among police officers, when this situation is combined with Obstructive sleep apnea/hypopnea syndrome (OSAHS), health consequences are greater, therefore we believe there is a need of research for these alterations. The aim of this study was to measure the changes in sleep architecture (SA) in police officers who currently have Night shift work (NSW) and OSAHS. Methods: We compared SA in 107 subjects divided in three groups: the first group included police officers with NSW and severe OSAHS (n = 48); the second group were non-police officers with diurnal work time and severe OSAHS (n = 48) and the third group was formed by healthy controls (n = 11)...
