Filter by:In the study titled Operational Ground Testing Protocol to Optimize Astronaut Sleep Medication Efficacy and Individual Effects (Phase 11), two randomized , blinded , placebo-controlled , cross-over trials will be conducted. The hypnotic medication and the placebo will be indistinguishable by subjects. Experiment 1 will involve N=14 subjects randomized to placebo , 10 mg Zolpidem (Ambien) and 10 mg Zaleplon (Sonata) in counterbalanced order and will be awakened 90 min. post-placebo administration (half at 60 min and half at 90 min). The latter will be done to maintain some degree of blinding relative to the participants knowledge of conditions and the staff working on the protocol. Zolpidem is the most commonly , and Zaleplon is the second most commonly , used sleep aid medication used in spaceflight. Females and those subjects who have had a previous adverse experience with 10 mg zolpidem will be placed into Experiment 2, which will involve N=20 subjects randomized to placebo , 5 mg zolpidem and 10 mg zaleplon. Data acquisition for both experiments will occur in the Astronaut Quarantine Facility ("AQF") at Johnson Space Center (JSC). Experimental methods and cognitive outcomes will be the same as those used in the pilot investigation titled Develop and Implement Operational Ground Testing Protocols to Individualize Astronaut Sleep Medication Efficacy and Individual Effects (Phase I). Combined , Experiment 1 and 2 will provide data on zaleplon 10 mg compared to placebo on a total of 34 subjects consisting of astronauts and other subjects considered analogous to the astronaut population (e.g., Flight Controllers, Flight Directors , Flight Surgeons, medical residents and medical students on National Aeronautics and Space Administration (NASA) rotation, and NASA/contractor employed University of Texas Medical Branch physician's) , which will provide the larger sample needed to identify those subjects who have cognitive performance deficits on abrupt awakening to the less sedating 10 mg zaleplon.
The proposed research will examine the role of physical activity (PA) on altering sleep quality (SQ) while systematically examining novel mechanisms that may drive changes in SQ. Specifically, the study will examine how a 2 week reduction in PA alters sleep quality in young, healthy individuals. Additionally, during this reduction in PA, the study will examine changes in inflammation, oxidative stress, and sympathetic activity to identify potential mechanisms for alterations in sleep quality.
Many teenagers do not get enough sleep. Obesity and diabetes are increasing in teenagers as well. This study plans to learn more about sleep and insulin resistance (insulin not working) in teenagers, and how these things may be related depending on sleep. This is important to know so that the investigators understand how sleep may play a role in health conditions like extra weight gain (increased food intake and less physical activity) and diabetes. To answer this question, the investigators plan to enroll teenagers who get <7 hours of sleep on school nights and measure changes in insulin sensitivity and dietary intake after a week of typical sleep (sleeping on their normal school schedule) and a week of longer sleep (spending 1+ hour longer in bed each night).
In a sample of 120 officers from Dane County law enforcement agencies, the investigators are conducting a randomized controlled trial of an 8-week mindfulness-based training program for police officers, Madison Mindfulness-Based Resilience Training (mMBRT), and investigating the impact of this training on subjective responses to stress, stress-related psychological and physical health outcomes, and biological and behavioral correlates of perceived stress. While the benefits of mindfulness-based interventions have been documented in a variety of populations, this will be the largest and most comprehensive study of its kind of law enforcement personnel. In addition to self-report measures, this study assesses an array of objective biological and behavioral outcomes both in the laboratory and in the field that may speak to mechanisms of change involved in symptom reduction.
In the research, we enroll 120 postoperative patients in the ICU and they will be assigned to four group: the eye patch group, the Dexmedetomidine(DEX) group, the eye patch+DEX group and the usual group. The sleep quality would be evaluated by the EEG monitor and the metabolic level, the inflammation and nutrition status would be detected.
Findings in neuroscientific research show that the environment one lives in has measurable effects on brain morphology and functioning. Human exposure to airborne infra- and ultrasound has been constantly increasing during the last decades. For instance, the European Renewable Energy Directive, established in 2009, lead to an increased use of wind turbines, generating infrasound. The EU Directive states that until 2020 a 20% of the EUs' total energy needs is to be generated with renewables, therefore the current infrasound load in the European environment will increase further. Similarly, ultrasound is ubiquitous in the modern public environment, emitted from public address systems, animal repellents, industrial machines, even toothbrushes. The present study aims to investigate potential long-term effects of exposure to infra- and ultrasound on subjective well-being, cognitive and brain functioning, as well as on brain structure. The study will apply a randomized-(placebo) controlled single-blind approach to investigate this subject.
Studies consistently show the negative health impact of sleep problems in both Alzheimer's disease (AD) patients and their caregivers. However, only a few sleep interventions have been conducted for AD patients or their caregivers in community settings and none have addressed both members of the dyad concurrently. To fill these gaps, this study aims to develop a sleep intervention program specifically tailored for AD patient/caregiver dyads who both experience sleep difficulties.
Thermal comfort and subsequent sleep quality will improve with the use of bedding that incorporates thermoregulation technology, in comparison to standard bedding products.
Sleep is a key factor for normal brain development of the newborn. However, it is poorly studied and little is known about its characterization, especially in premature infants. Body movements during sleep are easy to evaluate but studies on their relationship to normal sleep states are scarce and limited. This project aims to characterize body movements during sleep, assessed by electroencephalography, in very premature infants. Then, a correlation between body movements, sleep organization and neurodevelopmental outcome will be evaluated at 3 years of age.
The Nutritarian Women's Health Study (NWHS) is a long-term hybrid effectiveness-implementation study on the effect of the Nutritarian Diet on the occurrence, recurrence, and progression of chronic diseases (including all forms of cancer and cardiometabolic risk factors).
