Filter by:Fighter pilots have to perform tasks requiring high mental workload during moderate-intensity acceleration phases (2 to 3G) that can last several minutes. When these accelerations are performed in the body axis (+Gz), they induce a redistribution of blood flow in the lower limbs associated with a decrease in cerebral blood flow, partially compensated by activation of the sympathetic nervous system (baroreflex). The main hypothesis is that the effects of these prolonged accelerations, even of moderate intensity (<+4Gz), could impair pilots' ability to perform complex cognitive tasks, with potential consequences for flight safety and mission conduct. Moreover, flight missions are often performed after sleep debt, which is known to induce cardiovascular responses, sympathetic nervous system activation and impaired mental performance. The secondary hypothesis is that sleep debt (3h of time spent in bed) may increase the impairment of cognitive performance during prolonged acceleration.
The goal of this randomized controlled trial is to evaluate the impacts of an attachment-based intervention (Attachment Biobehavioral Catch-Up (ABC) and Home Book-of-the-Week (HBOW) program on emerging health outcomes (i.e., common childhood illnesses, body mass index, and sleep) in low-income Latino children (N=260; 9 months at enrollment). It is hypothesized that children randomized to ABC will have better health outcomes in comparison to the HBOW control group.
The intensive care unit (ICU) is recognizably detrimental to sleep and circadian health, and critical survivors frequently report the presence of alterations in this regard after hospital discharge. However, an appropriate evaluation of sleep and circadian rhythms is often neglected given the high associated cost and/or the need of collaboration of the patients. In this project, the investigators propose alternatives to ultimately improve the management of sleep and circadian health after critical illness. The researchers will evaluate the role of microRNA (miRNAs) expression profile in identifying the compromised sleep and circadian health of critical patients during the ICU stay, in the short (3 months after hospital discharge), and in the long-term (12 months after hospital discharge). Also, models based on machine learning techniques will be developed to predict adverse outcomes in this regard after hospital discharge.
This study plans to explore whether specially chosen relaxing music can help improve sleep, reduce stress, and prevent burnout in healthcare workers, many of whom are often sleep-deprived. The researchers will measure changes in brain activity, sleep patterns, and self-reported stress levels before, during, and after participants listen to this music. The novel approach includes using advanced brain scanning technology, sleep monitoring devices, and carefully selected music. Ultimately, the aim is to create a scientifically backed music intervention that can be used widely to help healthcare providers get better sleep and manage stress, potentially reducing burnout rates.
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.
Unhealthy sleep and cardiometabolic risk are two major public health concerns in emerging Black/African American (BAA) adults. Evidence-based sleep interventions such as cognitive-behavioral therapy for insomnia (CBT-I) are available but not aligned with the needs of this at-risk group. Innovative work on the development of an artificial intelligence sleep chatbot using CBT-I guidelines will provide scalable and efficient sleep interventions for emerging BAA adults.
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: 1. Can habitual sleeping habits predict, or do different types of sleepers alter, performance outcomes following sleep deprivation? 2. 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? 3. 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.
In a laboratory protocol in healthy adults, exposed to a prolonged period of wakefulness with a restricted opportunity for sleep (40h of wakefulness / 3h of sleep / 21h of wakefulness), we hypothesize that the relative increase in spectral power of Delta waves [ 1 - 4 Hz] in NREM in the frontal territory, identified as a potential marker of the restorative function of sleep, during a night of sleep with limited recovery (3 h of time in bed) after sleep deprivation (40 h of continuous wakefulness), will be less important in subjects with poor recovery in terms of cognitive performance than in those with good recovery.
In the treatment of Major Depressive Disorder (MDD), total sleep deprivation can produce rapid but short-lasting improvements in mood. In order to develop a new generation of treatments with rapid and sustained efficacy, a better understanding of the mechanism of action is urgently needed. One candidate mechanism is the modulation of synaptic strength mediated by glutamatergic activity as sleep deprivation has been suggested to increase synaptic strength. Although determining how sleep deprivation impacts the glutamatergic system is essential to isolating its mechanism of action, the invasive nature of most assessment methods has limited our ability to do so in humans. The proposed research aims to determine if changes in glutamatergic activity, reflecting the modulation of synaptic strength, underlie the antidepressant effects of sleep deprivation. In this project, the investigators will utilize a novel measure of glutamate imaging, GluCEST, to assess changes in glutamatergic activity, in addition to using a proxy measure, waking EEG theta activity, to assess synaptic strength following total sleep deprivation. Ten individuals (aged 25-50) with a DSM-V diagnosis of MDD will undergo baseline GluCEST imaging and waking EEG prior to and following approximately 30 hours of total sleep deprivation. Both clinician-administered and subjective mood measures will be collected. It is predicted that sleep deprivation will improve mood and increase glutamatergic activity and synaptic strength. Results from this project have the potential to identify the modifiable mechanisms by which rapid antidepressants work which could ultimately stimulate the development of novel interventions that work through the modulation of glutamatergic activity.
This study aims to examine the effectiveness of ammonia inhalants in countering the effects of total sleep deprivation on cognitive and physical performance tests relevant to military personnel.
