Active clinical trials for "Sleep Deprivation"

Sleep deprivation is a major problem in military populations. Some major consequences of sleep loss are inability to concentrate, poor work efficiency, and increase in errors during daily tasks. There is some evidence that ketone ester supplements may lessen the adverse effects of sleep restriction. The main purpose of these supplements is to raise your blood concentration of ketones, which are safe, small molecules that appear in the blood during fasting, when following a ketogenic diet, or consuming ketone supplements. The main purpose of this study is to examine if ingesting a ketone ester supplement, twice daily, can improve cognitive and physical performance during short-term sleep restriction.

The study is designed to investigate the impact of three nights of sleep restricted to 4 hours per night, on the processing and regulation of emotional information compared to Insomnia Disorder and control. The investigators will address and attempt to answer two questions. (i) How do three nights of reduced sleep or a diagnosis of Insomnia Disorder affect the processing and regulation of emotional information compared to typical, undisturbed sleep? (ii) What overlapping and distinct neural mechanisms are engaged and associated with behavioral effects when attempting to process and regulate emotions in a sleep restricted state or with a clinical diagnosis of Insomnia Disorder? This study will investigate sleep's role in emotion processing and regulation. The findings will help further understanding of the role of sleep in healthy emotional functioning.

Good and quality sleep, which has an important place in the lives of all living things; important for the health and well-being of children. Proper sleep habits are needed for quality and adequate sleep. According to the National Sleep Foundation, these habits include practices such as regular bedtimes, sleep routines, screen restrictions before bed. With the age of starting school in children; Due to the roles brought by school, lessons and social obligations, problems such as delay in bedtime and shorter sleep time are seen. Shortening of sleep time causes sleep deprivation. sleep deprivation; It is defined as a delay in bedtime and a shorter sleep time than would normally be due to intentional or daily activities. The use of sleep hygiene interventions to address sleep deprivation in children is highly effective. Sleep hygiene is a cost-effective method that is performed without the need for any additional material, consisting of both environmental and behavioral habits. In our study, a quasi-experimental pretest-posttest-control study design with a control group will be used to determine the effect of sleep hygiene education applied with the combined package program on sleep deprivation and sleep habits in children. After the necessary permissions are obtained, the classes will be divided into experiments and controls by drawing lots. To the experimental group; After the pre-test is applied, training and tasks will be given. In addition, a sleep hygiene policy will be sent to the families by phone every day. The total intervention will last four weeks, at the end of which a post-test will be administered. Two weeks will be waited without intervention, two weeks later the control measurement will be made. To the control group; Pre-test and post-test will be applied at the same time with the experimental group and training will be given after the post-test. The research data will be evaluated with the Statistical Package for the Social Sciences (SPSS) statistical program on the computer and in the form of numbers, percentages, averages and standard deviations for descriptive statistics in the computer environment and with necessary statistical analyzes. Significance will be accepted as p<0.05 at α=95% confidence interval.

The goal of the project is to determine the effects of noise masking and noise reduction on stress related physiological parameters in critically ill patients admitted to the intensive care unit.

This is a randomized controlled cross-over trial designed to measure the effect of one night's sleep deprivation on exercise endurance, ventilation and breathlessness in outpatients with COPD.

Sleep deprivation is a major problem in military populations. Some major consequences of sleep loss are inability to concentrate, poor work efficiency, and increase in errors during daily tasks. Ketogenic supplementation is speculated to alleviate some sleep deprivation issues via action of ketones. Ketones are small molecules that appear in the blood when following a ketogenic diet or consuming ketone supplements. The goal of this project is to find out if diet and/or ketones can improve sleep deprivation detriments over 5 days of sleep restriction (-50% from habitual sleep).

Urban children with asthma are at high risk for short sleep, due to an environment that jeopardizes both sleep and asthma management. Further, urban children with asthma suffer from altered immune balance, a key biological process contributing to individual differences in asthma morbidity and sleep health. In the proposed research, the researchers will examine the effects of shortened and recovery sleep on immune balance and associated changes in lung function in urban children with allergic asthma through an experimental design.

In the pediatric population, electroencephalographic (EEG) recordings are frequently performed in sleep, as it reduces the amount of artifacts and might activate epileptiform discharges. To date, no agreed-upon guidelines are available for hypno-induction for EEG recordings . Among the strategies used, the most commonly used are sleep deprivation, either total or partial, and the use of melatonin, alone or in combination. The investigators proposed a study aiming at evaluating the efficacy of a melatonin-based solution for sleep induction during EEG video recording VS sleep deprivation. In a randomized, crossover study, 30 pediatric patients (aged 4-10 years) will be subjected to two EEG recordings: in one they will receive the melatonin solution (5 mg), in the other they undergo only partial sleep deprivation (about 50% of physiological sleep). The primary endpoint of the study is represented by the time to fall asleep, secondary objectives are represented by frequency of epileptiform discharges, presence/absence of epileptic seizures, In addition, the levels of 6-sulfatoxymelatonina, the primary metabolite of melatonin in saliva and urine, will be determined with a validated LC-MS method.

The goal of this randomized crossover clinical trial is to determine if habitual sleeping habits can predict endurance performance following a night of partial sleep deprivation in healthy untrained, recreationally trained, and trained cyclists (18-50 years, ~50% females). The main questions it aims to answer are: Can habitual sleeping habits predict, or do different types of sleepers alter, performance outcomes following sleep deprivation? Does sleep deprivation alter blood pressure, heart rate, or metabolic responses during a 20-minute time trial, and/or are these altered amongst different types of sleepers? Can habitual sleeping habits predict, or do different types of sleepers alter, flow-mediated dilation following a night of normal sleep and/or sleep deprivation? Participants will be asked to perform 4 performance tests (20-minute time trial), 2 for familiarization, and 2 testing visits (1 under normal sleep and 1 under partial sleep deprivation). For 1 week prior to each testing visit, sleep will be tracked using an ActiGraph device. During each testing visit, and prior to the performance test, the vascular function of the superficial femoral artery will be assessed using a flow-mediated dilation technique. The investigators hypothesize that habitual early sleepers, poor sleepers, those with greater variability in sleep duration, and females will show the greatest impairments in performance and flow-mediated dilation following partial sleep deprivation.

More than 5 million patients are admitted to the intensive care unit every year in the United States; most of these patients experience profound sleep and circadian disruption. Promotion of circadian alignment (i.e., alignment of the body's clocks) would make it possible to strategically schedule behaviors such as sleep and eating at normal body clock times, which is predicted to improve sleep quality and metabolic function. This project will test the ability of a sleep chronobundle (i.e., sleep promotion and circadian treatment bundle) to normalize circadian alignment and subsequently test if this realignment also improves sleep and metabolism.
