STUDY OBJECTIVES To compare the efficacy and patient tolerance, compliance, and preference between auto-continuous positive airway pressure (CPAP) and constant CPAP. DESIGN Single-blinded, crossover, cohort study of consecutive patients with obstructive sleep apnea syndrome, with two treatment periods of 2 months each. PATIENTS Twenty-five patients (22 men, 3 women) with sleep apnea syndrom...

OBJECTIVE To study changes in sleep behavior and quality of life in obese children after adenotonsillectomy for obstructive sleep apnea. Study design and setting Prospective study at the University of New Mexico Children's Hospital. METHODS Children who met inclusion criteria and had a respiratory distress index (RDI) greater than 5 were enrolled in the study and underwent adenotonsillectomy....

BACKGROUND Respiratory failure is a significant cause of morbidity and mortality in neuromuscular diseases. Although clinical findings and respiratory function tests aid in diagnosing sleep-related breathing disorders, polysomnography is the gold standard for the diagnosis of these disorders. We aimed to investigate the role of sleep-wake symptoms and clinical findings of patients with Duchenne...

The aim of this study was to determine whether diaphragmatic fatigue develops over the course of the night in patients with obstructive sleep apnoea (OSA). Patients with severe OSA underwent overnight polysomnography with the addition of gastric and oesophageal catheters for measurement of transdiaphragmatic pressure (Pdi) (n = 7) and a gastro-oesophageal electrode for determination of diaphrag...

OBJECTIVE Sleep restriction results in decreased insulin sensitivity and glucose tolerance in healthy subjects. We hypothesized that sleep duration is also a determinant of insulin sensitivity in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS We studied seven patients (three men, four women) with type 1 diabetes: mean age 44 +/- 7 years, BMI 23.5 +/- 0.9 kg/m(2), and A1C 7.6 +/- 0...

Circadian phase resetting is sensitive to visual short wavelengths (450-480 nm). Selectively filtering this range of wavelengths may reduce circadian misalignment and sleep impairment during irregular light-dark schedules associated with shiftwork. We examined the effects of filtering short wavelengths (<480 nm) during night shifts on sleep and performance in nine nurses (five females and four ...

Introduction. The first night effect (FNE) is the tendency to have lower than usual sleep quality and quantity during polysomnography (PSG) recording, which alters architecture. FNE occurs in autism spectrum disorder (ASD), with studies suggesting that cardiac autonomic dysregulation altered patients this illness. Objective. To determine whether influences activity of ASD typically developing (...
