Background: Operating room technologists are constantly exposed to sleep disturbances due to their occupationally sensitive nature and these disorders lead to physical and psychological complications. Job stress is one of the important factors of physical and mental complications, as well as reduction of efficiency in operating room technologists. Methods: In this descriptive-analytical study,...
Background: Diabetes mellitus is one of the leading causes of death in the world as a result of a defect in the secretion or function of insulin. Sometimes insomnia can be a complication of diabetes or it can be a factor in diabetes. On the other hand, impairment in sleep quality is associated with increased risk of diabetes and mortality. Some studies have also shown that sleep deprivation has...
Introduction: Communication between mobile phones and antenna BTS (Base Transceiver station) is carried by electromagnetic waves that have energy, according to their nature. Increasing use of mobile phones because of the proliferation of antennas the concerns about them are proposed in society. In the present study the correlation between distance from the BTS antennas and the ...
Sleep and epilepsy have a complex interrelationship that is influenced by various factors, including the distinct stages of sleep. Non-rapid eye movement sleep promotes epileptic activity, while rapid suppresses it. Seizures can be triggered sleep, deprivation increases seizure susceptibility. Epilepsy disrupts architecture quality, leading to disturbances comorbidities, like apnea restless leg...
Activity-based sleep-wake monitoring or actigraphy has gained a central role as a sleep assessment tool in sleep medicine. It is used for sleep assessment in clinical sleep research, and as a diagnostic tool in sleep medicine. This update indicates that according to most studies, actigraphy has reasonable validity and reliability in normal individuals with relatively good sleep patterns. The va...
BACKGROUND Sleep pattern is an important factor in a child's mental, behavioural and physical status. To evaluate the sleep patterns of children, subjective tools such as sleep logs and questionnaires are still widely used in addition to objective methods of sleep assessment. Despite the established correlation between subjective and objective sleep variables, the characteristic features of sub...
Sleep problems have not been directly reported in phenylketonuria (PKU). In PKU, the metabolic pathway of phenylalanine is disrupted, which, among others, causes deficits in the neurotransmitters and sleep modulators dopamine, norepinephrine, and serotonin. Understanding sleep problems in PKU patients may help explain the pathophysiology of brain dysfunction in PKU patients. In this explorative...
Resting state functional magnetic resonance imaging (rs-fMRI) in infants enables important studies of functional brain organization early in human development. However, rs-fMRI in infants has universally been obtained during sleep to reduce participant motion artifact, raising the question of whether differences in functional organization between awake adults and sleeping infants that are commo...
AIMS Chronic heart failure (CHF) and sleep-disordered breathing (SDB) are often co-existing problems among the elderly. Apnoeic events may cause cognitive impairment. The aim of the study was to compare sleep and wake patterns, insomnia, daytime sleepiness, and cognitive function in community-dwelling CHF patients, with and without SDB, and to investigate the association between sleep-related f...
How stable are neural activity patterns compared across periods of sleep? We evaluated this question in adult zebra finches, whose premotor neurons in the nucleus robustus arcopallialis (RA) exhibit sequences of bursts during daytime singing that are characterized by precise timing relative to song syllables. Each burst has a highly regulated pattern of spikes. We assessed these spike patterns ...
