Filter by:Sleep is a crucial factor for athletes' health and recovery. Many variables are able to negatively influence the sleep of top-level athletes, such as: anxiety, long travels, high volume or high-intensity training period, and a nigth competition too. Therefore, the aim of this pilot study is to evalute how sleep quality changes in relation to a late nigth competition in athletes.
A feasibility study to evaluate the use of white noise to improve sleeping conditions in an ICU setting.
Currently, residents commonly experience dehydration and poor nutrition during nighttime duty hours as a result of heavy work load, lack of time to take nutrition and hydration breaks, or limited or no access to healthy food and drinks which may affect residents' work performance. The goal of this study is to compare the effects of two different meal compositions with no typical dietary practices (existing conditions) on work performance of the on-call residents during night shifts.
Partial sleep deprivation (PSD), is a common problem among current university students in Taiwan. Students often get inadequate sleep time due to burden schoolwork during exam period. In recent years, Issue of sleep quality has gradually been emphasized. According to previous research, lacking in sleep easily results in sleepiness, fatigue, and poor problem-solving performance. Sleep deprivation may also affects cognitive performance, like reducing working memory performance. Furthermore, sleep deprivation will probably alter autonomic nervous function, such as sympathetic/parasympathetic activity change. Previous researches also suggested that sleep deprivation may associated with the risk of being obesity or suffering from diabetes. However, most researches focused on the effects of total sleep deprivation, especially those who usually have night shift work, such as medical staff. Few studies investigated the cognitive function and physiological function of university students after a period of time of partial sleep deprivation. As a results, the aim of the study is to investigate how partial sleep deprivation affects the cognitive performance and physiological function before and after the final exam period in healthy young university students between 20 and 30 years old in Taiwan, in order to promote the importance of healthy sleep and improve sleep quality among university students.
The aim of this trial is to investigate the effects of a single bout of aerobic exercise on sleep in patients with depression.
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).
Chronic sleep deprivation among adolescents is a prevalent health problem across the world and is associated with a series of short and long term consequences. However, effective interventions targeting on this vulnerable adolescent population is very limited. Majority of the previous sleep education programme are conducted in a school context which personal factors and individualized problems were not addressed. In addition, failure to address "knowledge-action gap" may also explain why individual fail to enact health behaviors even holding positive motivation. In regard to this, investigators proposed an active and person-oriented protocol with the aid of advanced technology in order to improve adolescent sleep health.
Prior research studies have shown benefit for use of a technique called High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM®), to reduce symptoms of moderate to severe insomnia. HIRREM uses scalp sensors to monitor brain electrical activity, and software algorithms translate selected brain frequencies into audible tones in real time. Those tones (acoustic stimulation) are reflected back to participants via ear buds in as little as four milliseconds, providing the brain an opportunity to self-adjust and balance its electrical pattern. The purpose of this research study is to determine the effects of HIRREM-SOP, an updated version of this technology that is based on the HIRREM approach, but now includes new hardware and software, a standardized series of HIRREM protocols, and a fixed number of sessions. Adults over the age of 18 who have documented sleep trouble that place them in the category of subthreshold (mild), moderate, or severe clinical insomnia as defined by the Insomnia Severity Index, are eligible to participate in the study.
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 project is aimed at identifying how the adrenergic antagonist 'carvedilol' modulates the effects of sleep deprivation in healthy volunteers. The study is a double-blind, randomized, placebo-controlled, cross-over study. Investigators will include 20 healthy volunteers who will undergo three functional magnetic resonance (fMRI) imaging sessions, one at baseline, and two after sleep deprivation (one night without sleep). The two sleep-deprivation scans are performed in a randomized order where subjects receive placebo or carvedilol, in a within-subject, cross-over study design. The following domains will be described: 1) fMRI imaging of cerebrospinal fluid (CSF) pulsations (glymphatic flow) in the human brain, performed by a combination of fMRI protocols that includes structural (T1, T2, diffusion weighted) and functional (multiband/fast imaging, spectroscopy) imaging. 2) fMRI imaging during wakefulness and sleep are determined by simultaneous electroencephalographic (EEG) recordings. 3) The effects of sleep deprivation on the fMRI derived glymphatic flow signal. 4) The effects of the adrenergic antagonist carvedilol on fMRI measurements and sleep intensity. 5) Quantification of cognitive performance before and after a nap in the MRI. Cognitive testing includes: assessments of visual attention, reaction time, paired-associative memory, working memory, emotional recognition and subjective ratings of sleepiness and mood.
