Cheyne-Stokes respiration (CSR) is common in patients with congestive heart failure (CHF). This characteristic crescendo-decrescendo pattern of breathing is often seen during sleep in patients with CHF and is a form of central sleep apnoea. Disordered nocturnal breathing leads to oxygen desaturation, poor sleep quality, and altered sleep architecture. These features may lead to complaints of da...

Obstructive sleep apnea is associated with significant daytime sleepiness, reduced quality of life, insulin resistance, motor vehicle crashes, vascular morbidity and mortality. Current evidence supports the belief that all these parameters can be impacted favorably by treatment. Medical therapy with positive pressure eliminates snoring and favorably affects daytime sleepiness, driving risk, vas...

OBJECTIVE While individuals with insomnia consistently complain of cognitive impairment, previous studies on the effect of insomnia on objective measures of cognitive function have obtained ambiguous results. The relationship between daytime sleepiness and cognitive manifestations in insomnia patients is not clear. METHODS Thirty-six primary insomnia patients (PIPs) and 26 good sleep controls...

It was hypothesized that adult cystic fibrosis (CF) patients with severe lung disease have impaired daytime function related to nocturnal hypoxaemia and sleep disruption. Nineteen CF patients (forced expiratory volume in one second 28+/-7% predicted) and 10 healthy subjects completed sleep diaries, overnight polysomnography (PSG), and assessment of daytime sleepiness and neurocognitive function...

Abstract Artificial light at night has rapidly spread around the globe over last decades. Evidence is increasing that it adverse effects on behavior, physiology, and survival of animals plants with consequences for species interactions ecosystem functioning. For example, artificial disrupts plant-pollinator this can have plant reproductive output. By experimentally illuminating natural communit...

It was hypothesized that triazolam might decrease central apneas associated with arousal periods in patients with central sleep apnea by hastening the onset of consolidated sleep. Five male patients, diagnosed as having central sleep apnea on a screening night, participated in a double-blind randomized crossover study of the effect of placebo, 0.125 mg triazolam, and 0.25 mg triazolam on sleep,...

background the prevalence of vesicoureteral reflux (vur) is higher in enuretic children than in non-enuretic children. recent studies have reported vur in 6–23% of children with enuresis. objectives to clarify the association of nocturnal enuresis with vesicoureteral reflux (vur) and to identify children who are at risk for vur. conclusions vur is uncommon in children with mne and in those with...

Measures of excessive daytime sleepiness, neuropsychologic function, and mood were assessed in twenty-two persons with mid-stage Parkinson's disease (PD) and sixteen age-matched healthy controls. Levodopa dose equivalents (LDE) were computed for the patients. While Epworth sleepiness score (ESS), Mini Mental State Exam, logical memory, Stroop, and the mood scales, reliably distinguished patient...

Sulfur mustard (SM) is a toxic agent that targets several tissues. It is the leading cause of persistent lung disease, progressive deterioration in lung function and mortality among patients. Disturbed sleep and poor quality of sleep are common in SM-exposed patients with chronic respiratory problems. Melatonin is an alternative medication that has been widely used to treat poor sleep quality c...
