The aim of this study was to evaluate (1) the prevalence of periodic leg movements during sleep (PLMs) in a consecutive sample of congestive heart failure (CHF) outpatients; (2) the presence of correlation between PLMs, subjective daytime sleepiness, and sleep architecture; and (3) the heart rate response to PLMs in CHF. Seventy-nine [50 men, age 59 ± 11(More)
The aim of this study was to evaluate the effects of a 2-month exercise training associated with continuous positive airway pressure (CPAP) treatment on the subjective and objective sleep measurements, quality of life, and mood in moderate to severe obstructive sleep apnea syndrome (OSAS) patients. Male patients were randomized into two treatment groups:(More)
Sleepiness is a physiological function, and can be defined as increased propension to fall asleep. However, excessive sleepiness (ES) or hypersomnia refer to an abnormal increase in the probability to fall asleep, to take involuntary naps, or to have sleep atacks, when sleep is not desired. The main causes of excessive sleepiness is chronic sleep(More)
The literature widely recognizes that shift workers have more health complaints than the general population. The objective of this study was to describe the prevalence of sleep complaints and verify the polysomnographic (PSG) variables of shift workers in two Brazilian nuclear power plants. We carried out a subjective evaluation with a sleep questionnaire.(More)
The aim of this study was to determine whether an orientation session led by a polysomnography (PSG) technician during the night of positive airway pressure (PAP) titration can improve objective sleep quality and acceptance of nasal mask in patients referred to a sleep laboratory. Consecutive patients (n = 1,481), referred for PAP titration during PSG, were(More)
Cases of violent behavior during sleep have been reported in the literature. However, the incidence of violent behavior during sleep is not known. One epidemiological study showed that approximately 2% of the general population, predominantly males, presented violent behavior while asleep. In the present study, the authors describe clinical and medico-legal(More)
INTRODUCTION Studies that assess the upper airways in sleep-related breathing disorders have been performed only in patients with obstructive sleep apnea syndrome who seek medical attention. Therefore, in addition to the need for population studies, there are no data on the orofacial-cervical physical examination in subjects with upper airway resistance(More)
INTRODUCTION The cardiovascular system (CVS) is heavily influenced by the autonomic nervous system. Additionally, there is a functional alteration during the various stages of sleep. In nonrapid eye movement (NREM), a state of cardiovascular relaxation occurs during stages three and four. A large amount of rapid ocular movements is concentrated in rapid eye(More)
Casos de comportamento violento (CV) durante o sono são relatados na literatura. A incidência de comportamento violento durante o sono não é muito conhecida. Um estudo epidemiológico mostra que cerca de 2% da população geral apresentava comportamento violento dormindo e eram predominantemente homens. Neste artigo, os autores descrevem aspectos clínicos e(More)
This article presents a software developed for analysis of phenomena related to the Power Quality (PQ) in industrial systems, as variation of voltage, harmonic distortion and imbalance voltage, where the results are conveniently visualized in an user-friendly interface. This software intends to replace, in most situations, measurements made by traditional(More)
