Active clinical trials for "Sleep Deprivation"

The overall goal of the present application is to test the hypothesis that shift workers, who are chronically exposed to circadian misalignment and sleep loss, have a higher cardio-metabolic risk than day workers, and that the accumulated sleep debt and the degree of circadian misalignment both predict their elevated cardio-metabolic risk.

Study the impact of the WHOOP fitness tracker on burnout in attending and resident otolaryngologists

The investigators are going to compare the sleep quality and quantity between dexmedetomidine group and midazolam group using 24 hour polysomnography in critically ill patients. And the investigators also compare the incidence of delirium between the two groups.

It is known from the literature that patients in the Intensive Care Unit do not get enough sleep impacting on short and longterm recovery (Tembo & Parker, 2009; Bihari et al, 2012; Kamdar et al, 2012). The use of non-pharmacological interventions such as massage with essential oils is supported by the literature as being useful in encouraging sleep (Richards et al, 2003; Matthews, 2011). Over 30% of cancer patients are accessing complementary therapies such as these (Rees et al, 2000; Lewith et al, 2002). We propose investigating whether aromatherapy massage and the use of essential oils in the form of an Inhalation Patch (Bioesse TM) prove to be a useful intervention for improving patient sleep whilst on the critical care unit.

The aims of this study are examine the effects of sleep deprivation in muscle recovery after a maximum eccentric resistance exercise session performed on an isokinetic dynamometer (24 series of 10 repetitions). The sample will consist of 10 men, sedentary, clinically healthy, aged between 20 and 31 years old. Two experimental groups will be developed: EXE-SLEEP, in which subjects will perform the exercise protocol (~18:00-19:00) and will be subject to normal period of sleep for 3 nights; EXE-TOTAL, in which subjects will perform the same exercise protocol and will be sleep deprived for 60 hours, followed by one night of sleep rebound.

Sleep deprivation in healthy volunteers is associated with immune dysfunction. This adverse effect of sleep deprivation likely occurs in patients suffering from acute injury and critical illness requiring intensive care unit (ICU) admission. Studies have demonstrated that sleep in ICU patients is highly abnormal. The global hypothesis for this proposal is that a strategy to promote sleep in ICU patients will increase time in rapid eye movement (REM) and slow wave sleep (SWS). This three phase proposal examines the feasibility of a sleep promotion strategy for injured and critically ill patients in the ICU. Phase I (Development and Training): Develop an intervention manual for sleep promotion, Sleep Enhancement Program (SEP), and train ICU staff. Phase II (Validation and Safety): Implement SEP and test for protocol fidelity and safety. Phase III (Efficacy): Conduct a pilot trail to determine efficacy of SEP to improve SWS in ICU patients.

The purpose of this study is to determine whether partial sleep deprivation, as compared with normal sleep, influences certain metabolic and cognitive parameters, related to food intake, hunger and memory functions, when participants are shielded from external time cues.

Very premature birth and the necessary hospitalization expose to a risk of morbidity and mortality which impacts the neurodevelopmental prognosis. Sleep and behavior monitoring have not been developed in the neonatal units. This has to be improved since it is known from clinical and animal studies that the quality, organization and quantity of sleep in very preterm infants impact neurological development and brain plasticity. The collection system provide neonatal care nurse with access to motion curves (evaluated by signal processing of live video) and real-time infrared video (also available in low-light conditions). This new non-invasive technology allows an evaluation of the activity cycles of the newborn by the caregivers which until now was only accessible occasionally by short recordings of actigraphy or polysomnography. The investigators wish to demonstrate that this can contribute to an organization of care that respects the sleep patterns of the newborn, which they know to condition the neurodevelopmental prognosis.

Metabolism is increasingly recognized as being highly regulated by anticipatory biological rhythms (circadian rhythms or "biorhythms"), which are driven by molecular feedback loops, and which are approximately 24 hours long ("circa diem"). These circadian rhythms exist both centrally, in the brain, but also in the periphery, and are specific to many tissues depending on their main biological function or functions. Whereas these circadian rhythms have been thoroughly characterized in other organisms, their role in humans remain poorly understood, partly because of the difficulty in studying these rhythms in peripheral tissues. The investigators therefore aim to characterize these rhythms in primarily skeletal muscle and adipose tissue in healthy young volunteers (using the so-called constant routine paradigm), and how these rhythms interact with one another at various genetic and molecular levels. At the same time, the investigators aim to study how an unhealthy vs. healthy diet can alter these circadian rhythms, and how they interact with circadian rhythms in other tissue compartments such as those expressed by blood cells.

The purpose of this study is to examine the consequences of chronic sleep restriction on nighttime sleep, daytime alertness, performance and memory functions, and metabolic and cardiovascular function, and to determine if the consequences of chronic sleep restriction differ between healthy young and older adults.
