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.
Sleep disorders and disturbances are mostly underestimated in clinical practice. Moreover, this problem is generally neglected by the pregnant themselves. Today, it is important to underline any problem that may have an affect to improve the quality of life during pregnancy. This study assesses the sleep quality, insomnia patterns and obstructive sleep apnea in the second and third trimesters of pregnancy.
The present project is aimed to contribute with new knowledge concerning how light conditions in the physical environment can be manipulated to alter the sleep and circadian rhythms of individuals with an evening-type circadian rhythm. More precisely, the study will explore whether exposure to blue light (compared to a full spectrum light control condition) during the morning hours advance the circadian rhythms of evening-type individuals, towards that which is more similar to the daily rhythm of morning-type individuals. This study is important as it has been found that evening-type adolescents and adults are at higher risk of poor academic performance and demonstrate lower intellectual performance when tested at their nonoptimal early times of day, and given the fact that most schools and workplaces structure their working hours during such early hours of the day. Such an intervention could thus help evening-type individuals better adjust to the different early day requirements that they are exposed to. The project involves a three-day intervention where participants will be exposed to blue monochromatic light, administered through ceiling mounted light emitting diode (LED)-based room lighting, in the early hours of each morning for a duration of 60 min. The participants' sleep, circadian rhythm and waking function will be assessed both objectively and subjectively. The effects of the intervention are transferable to real life educational and work settings and can thus be applied in naturalistic settings. The intervention is based on the new laboratory infrastructure available at the sleep laboratory situated in Christies gate 12.
BACKGROUND: The influence of sleep extension on glucose homeostasis in adolescents at risk for type 2 diabetes is unknown. This issue is of high clinical relevance given the high prevalence of sleep deprivation in this population and the accumulating body of evidence indicating that having a good night's sleep is important for the prevention of chronic diseases including type 2 diabetes. OBJECTIVE: To determine if extending sleep duration improves insulin sensitivity in adolescents presenting with risk factors for type 2 diabetes. HYPOTHESIS: It was hypothesized that compared with decreasing sleep duration, increasing sleep duration by 1.5 hours over 1 week will improve insulin sensitivity. METHODS: Using a randomized, counterbalanced, 2-condition crossover design, 30 obese adolescents between 13 and 18 years of age who have insulin resistance will complete the study. Participants will sleep their typical amount at home for 1 week and will then be randomized to either increase or decrease their time in bed by 1.5 hours per night for 1 week, completing the alternate schedule on the fourth week (washout period of at least 1 week between sleep conditions). This procedure will result in a targeted 3-hour time in bed difference between conditions. Sleep will be objectively measured using actigraphy (Actiwatch) and sleep schedule adherence will be promoted by providing fixed bedtimes and wake times during the experimental weeks, and will be monitored through phone calls to the research center. Participants will also be compensated for keeping the sleep schedule and daily calls to enhance adherence. The outcome measures will then be compared between both sleep conditions at the end (on day 8 of each study week). The primary outcome measure will be insulin sensitivity as measured by the Matsuda index (total body insulin sensitivity). Secondary outcomes will include the homeostasis model assessment of insulin resistance (HOMA-IR), blood lipids, food intake and physical activity. Repeated measures analysis using the mixed model will be used to assess the effect of the two sleep interventions on insulin sensitivity. RELEVANCE: The study will provide the first robust clinical evidence to determine if increasing sleep duration in youth at risk for type 2 diabetes improves insulin sensitivity. This information will be essential for clinical and public health guidelines for type 2 diabetes prevention among adolescents.
This study aims to evaluate the accuracy of automated sleep analysis by the Dreem dry-EEG headband and deep learning algorithm in comparison to the consensus of 5 sleep technologists' manual scoring of a gold-standard clinical polysomnogram (PSG) record in healthy adult volunteers during an overnight clinic-based sleep study.
Sleep is essential for children's daytime functioning and health. Poorer sleep hygiene can negatively affect sleep outcomes in children. Urban Latino children are at greater risk for poor sleep hygiene and poor quality sleep due to exposure to higher levels of urban and cultural stressors. This project aims to refine and test a novel school-based intervention to improve sleep hygiene and in turn, sleep quality in urban Latino middle school children. An existing sleep hygiene intervention that has been shown to improve sleep in urban children will be culturally and contextually tailored and has the potential to exert greater improvements in sleep hygiene and sleep outcomes for this high-risk group.
The importance of good sleep has been gaining interest in critically ill patients as poor sleep is associated with increased rates of delirium, non-invasive ventilation failure and stress to the patient. The use of earplugs and eye masks has been shown to result in longer sleep time and better sleep quality. The primary outcome of this randomized control trial is to evaluate if the use of eye masks and earplugs in patients undergoing major abdominal surgery will lead to improved sleep quality. Secondary outcomes include the level of noise intensity in the various monitored units, incidence of delirium, nursing demand, length of hospitalization and anaesthetic techniques. With these findings, we hope to be able to improve patients' overall satisfaction with the healthcare received.
The aim of this trial is to investigate the effects of a single bout of aerobic exercise on sleep in patients with depression.
Sleep is one of the basic and indispensable daily life activities that affect the quality of life and health of individuals and is a concept with physiological, psychological and social dimensions. In the literature, sleep difficulties and problems have begun to be investigated in children with acute lymphoblastic leukemia and have not been found in national publications. In these children, sleep quality, strengths and disorders and a study evaluating this variation on a scale have not been found. For this reason, our study will be done in order to determine the factors affecting sleep and sleep in children with cancer and to show the effect of exercise on these factors.
This study aims to evaluate the accuracy of apnea detection and automated sleep analysis by the Dreem dry-EEG headband and deep learning algorithm in comparison to the consensus of 5 sleep technologists' manual scoring of a gold-standard clinical polysomnogram (PSG) record in adults during a physician-referred overnight sleep study due to suspicion of sleep-disordered breathing.
