Filter by:The overall goal is to determine how a sleep extension intervention (increasing time in bed) in individuals who maintain less than 6.5 hours sleep per night affects their plasma ceramides and insulin sensitivity. Participants will undergo a randomized controlled trial, with sleep extension (intervention) and healthy lifestyle (control) groups. The sleep extension is designed to increase participant's time in bed by 2 hours per night. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
Estimating that people sleep on average up to two hours less over the last decades, sleepiness and fatigue need to be considered as significant societal problems of the modern world. Jurisdiction is precise on how to deal with overtired offenders since they were not allowed to use machines or vehicles in the first place, similar to drunk individuals or consumers of illicit drugs. In contrast to alcohol or illicit drug use, however, there are no quick roadside or workplace tests as objective (analytical) biomarkers for sleepiness. Investigators hypothesize that increasing sleep drive or impaired wakefulness can be assessed by qualitative or quantitative fluctuations of certain metabolites in biological specimens, e.g., accumulation or decrease of endogenous substances related to sleep debt. Thus, this sleep study provides the necessary biological samples of either sleep-deprived, sleep-restricted, or control subjects, which are then analysed for appropriate metabolite biomarkers utilizing an untargeted metabolomics approach. In addition to established impairment tests, a state of the art driving simulator will be employed to objectively measure driving performance under all study conditions. Participants will also rate their subjective sleepiness using validated questionnaires.
The purpose of this study is to look at how sleep disordered breathing (SDB) and not getting enough sleep each night contribute to daytime sleepiness. The investigators also want to determine the treatment that works best for improving daytime sleepiness. In this study, the investigators are comparing 2 programs that may improve symptoms of daytime sleepiness.
This protocol will increase sleep duration in participants who maintain less than 6 hours sleep per night, to target the recommended 7 hours of sleep per night. The focus of this study is determine how increasing nightly sleep duration in these individuals who maintain less than 6 hours sleep per night changes their plasma metabolome and insulin sensitivity. The primary outcome will examine changes in branched-chain amino acids and the secondary outcome will examine changes in insulin sensitivity. The investigators will also determine if changes in plasma metabolites can be used as a biomarker to discriminate between adequate versus insufficient sleep.
This study is a nonrandomized, unblinded, uncontrolled case series clinical trial validating the SmartSleep product, including SleepMapper app in the home setting. It is intended to provide data related to product use and cognitive testing incorporating a longer baseline period for comparison purposes. It will include adults (21-50 yr. old) who are working full time and report shortened sleep due to lifestyle. For the purposes of this study, shortened sleep is defined as sleeping at least 5 hrs. of sleep per night, and sleeping less than or equal to 7 hrs. at least 3 nights per week. Participants also increase their sleep duration by ≥ 1 hour on the weekends. In addition, participants report a sleep latency ≤ 30 minutes less than or equal to 3 nights per week. Participants are generally healthy individuals who have not been diagnosed with any sleep-related medical conditions. In addition, participants diagnosed with major organ system diseases or requiring oxygen therapy are excluded from participation. Up to 75 individuals will be consented in order to complete a total of 50 participants using a nonrandomized design. The study involves an initial screening visit followed by home use of the SmartSleep device with SleepMapper app. The home use will include an initial week of baseline use followed by 3 weeks of use with boost on. Study staff will contact participants after the first week of use as a reminder. Participants will be asked to complete a battery of cognitive tests upon wake up each morning. Participants will be asked to complete a question twice daily during the home use period. Additional phone calls may occur on an as needed basis if issues arise. The final visit will be an in facility visit in which all study equipment will be returned. The anticipated study duration will be up to 6 weeks (including the 4 weeks of use period).
This study is a randomized, single-blind, sham-controlled pilot cross-over trial comparing the feasibility, and efficacy of 2 nights of in lab use with active versus sham conditions in adults with sleep restricted schedules. The study involves the testing of 2 different prototypes both in the sham and active conditions The expected duration of the study for each participant is up to 5 weeks. It will include adults (21-50 yr. old) who report shortened sleep due to lifestyle. For the purposes of this study, shortened sleep is defined as sleeping at least 5.5 of sleep per night, and sleeping less than or equal to 7 hours of sleep +/- 15 minutes on at least 3/5 work/school nights. Participants also increase their sleep duration by ≥ 1 hour on non-work/school days. In addition, participants report a sleep latency ≤ 30 minutes and wake after sleep onset ≤ 30 minutes. Participants are generally healthy individuals who have not been diagnosed with any sleep-related medical conditions such as obstructive sleep apnea, insomnia, difficulty falling asleep on a nightly basis and deny difficulty staying asleep if awoken during sleep. In addition, participants diagnosed with major organ system diseases or requiring oxygen therapy are excluded from participation. Up to 60 individuals will be consented in order to complete a total of 10 participants using a cross over design. The study involves an initial screening visit followed by 1 week of actigraphy measurement to determine eligibility. Post eligibility, participants will undergo an additional week of actigraphy measurement. Participants will complete 2 overnight visits in the sleep lab per week, with one washout night in between. They will be randomly assigned to sham or active condition during the first of the overnight visits, and the other condition during the second overnight condition. Participants will return to the lab on the same nights the next week and receive the second device in both conditions. Participants will be asked to complete a battery of cognitive tests upon wake up in the lab after each of the overnight visits.
The study aims to develop and test a user-friendly, accessible approach to sleep assessment which can function as an initial "triage" of targeted sleep conditions, such as insomnia, insufficient sleep syndrome, sleep apnea syndromes/snoring, and circadian sleep/wake disorders, within the clinical and community population. Specifically, this study will test the validity and reliability of a self-rated, digitized, and cost-effective diagnostic measure with sufficient sensitivity to accurately assess/diagnose common sleep conditions and/or risk for these conditions. Such an approach, would allow for faster assessment of common sleep conditions and disorders, and provide clinical knowledge to the individual, the physician, and if required insurance companies, as to those persons who need more immediate attention or treatment for their sleep condition.
The primary objective of this study is to evaluate the impact of provision of a child bed through the Beds for Kids program on objectively measured child sleep, and on daily child behavioral functioning and caregiver functioning over a 14-day period for preschool-aged children.
This study is a randomized, double-blind, placebo-controlled cross-over study designed to evaluate the effectiveness and efficacy of 2 consecutive work days of nightly use of active versus sham PowerSleep devices in adults with self-imposed restricted sleep schedules. The primary analysis will be intent-to-treat with the secondary analysis as an as-treated analysis. The expected duration of the study for each participant is up to 4 weeks.
Sleep and wakefulness disorders impact 50 to 70 million Americans and insufficient sleep is epidemic with over 50% of Americans reporting less than 7 hours of sleep per night. Health problems associated with insufficient sleep include inflammation, depression and anxiety, diabetes, stress, drug abuse, poor quality of life, obesity, and fatigue related accidents on the job/while driving. While the contribution of sleep to overall health, well-being, and public safety is recognized, no established clinical biomarkers of sleep deficiency exist. Such biomarkers would have utility as road-side biomarkers of sleepiness (e.g., drowsy driving), monitoring on the job fatigue/fitness for duty (e.g., transportation, military ops health care), monitoring sleep health, as well as for clinical diagnostics and measures of clinical treatment outcomes. Thus, investigators designed a controlled laboratory insufficient sleep protocol utilizing metabolomics to identify biomarkers of insufficient sleep. Investigators propose to identify changes in metabolites that consistently occur during insufficient sleep. As an exploratory outcome investigators will examine associated changes in metabolites and cognitive performance during insufficient sleep.
