Filter by:In this multicentric controlled study, we aims to evaluate effect of caffeine on mental performances during a sleep deprivation protocol. Genetic polymorphisms are considered as a covariable.
Background:There are still many gaps in research concerning the effect of different physical training modalities on sleep quality in the population underwent coronary artery bypass graft surgeries(CABG).Purpose:The present study was conducted to compare the quality of sleep in subjects who underwent CABG, were submitted to two types of training (i.e, aerobic exercise alone or combined aerobic and resistance training
People living with HIV (PLWH) often have poor sleep, which may put them at a higher risk for many chronic diseases, including cardiovascular disease. One of the mechanisms by which this may occur is via chronic inflammation and endothelial dysfunction. Adenosine plays an important role in sleep homeostasis, with levels increasing in the CSF in response to sleep deprivation and falling with sleep. Peripherally, adenosine, via its signaling pathway, plays an important role in immunoregulation by suppressing the inflammatory response. PLWH, even on antiretroviral therapy, have suppressed peripheral adenosine levels which are predictive of adverse cardiovascular outcomes. The hypothesis underlying this study is that acute sleep deprivation in PLWH does not result in a compensatory increase in extracellular adenosine and its signaling peripherally, and this failure to appropriately compensate, leads to an increase in systemic inflammation and endothelial dysfunction.
Major surgery can lead to postoperative disturbances in sleep patterns with subjective deterioration of sleep quality according to patients' reports as well as objective alterations of sleep architecture, as recorded by polysomnography Factors implicated in postoperative sleep disturbances include but are not limited to the severity of the surgical procedure, the neuroendocrine response to surgery, inadequate treatment of postoperative pain and external factors interfering with sleep, such as light, noise and therapeutic procedures There are no adequate data from current literature as to whether regional anesthesia is superior to general anesthesia regarding postoperative sleep quality in patients subjected to either mode of anesthesia. So, the aim of this study will be to assess the effect of two different anesthetic techniques (general versus regional) in patients subjected to similar operations Patients will be assessed with the Pittsburgh Sleep Quality Questionnaire (PSQI), regarding preoperative and long term postoperative sleep quality and sleep diaries regarding early postoperative sleep quality
A sleep deprivation protocol combined with state-of-the-art, simultaneous positron emission tomography and magnetic resonance spectroscopy imaging will be employed to investigate the effects of sleep deprivation and aging on hypothesized molecular markers of sleep need.
The purpose of this study was to evaluate differences in cognitive functions at baseline and following night shift at a trauma center among faculty anesthesiologists.
It is well established that patients sleep poorly in the Intensive Care Unit (ICU), and excessive noise is considered to be a modifiable cause of this. Previous studies have tried to reduce ambient noise by educating staff and fixing noisy equipment. Other studies have tried to reduce the noise experienced by patients by supplying them with active noise cancelling headphones and earplugs. In this study we are combining Active Noise Cancelling headphones with white noise to try and reduce noise experienced by patients, with the aim of improving their sleep. Sleep deprivation is known to negatively impact health, and so improving sleep may improve patient outcomes as well as improve the patient's experience in critical care. The Investigators will screen all patients in the critical care wards in the Royal Infirmary of Edinburgh. Patients that are receiving ventilation, are delirious or have already been enrolled in the study will be excluded. After allowing patients to give informed consent, we will randomise them into one of two study groups: Study group A will receive standard care on the 1st night (no headphones), and will receive the intervention (active noise cancelling headphones with white noise) on the 2nd night. Study group B will receive the intervention on the 1st night, and will receive standard care on the 2nd night. All patients will wear a Xiaomi MiBand 2 wrist band, that tracks movement and sleep. Patients will fill in the Pittsburgh Sleep Quality Index at the beginning of the study to establish usual sleeping habits. Our primary outcome measure is the mean score on the Richard Campbell Sleep Questionnaire (RCSQ), which will be filled in by the patient the morning after each night. Our secondary outcome measure is the data from the wrist band, noise levels measured overnight, and patient experience of the intervention.
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.
To further understand the impact of acute sleep deprivation and recovery sleep on the processing of emotional information the investigators will address and attempt to answer three questions, (i) how both undisturbed sleep and sleep deprivation affect the processing and retrieval of emotional information, (ii) what neural and psychophysiological mechanisms are associated with these behavioral effects, and (iii) to explore the ability of recovery sleep to reverse the effects of sleep deprivation. Together, these studies will provide a greater breadth and depth of knowledge concerning sleep's role in emotion processing and regulation. Given the growing societal tendency to view sleep as unproductive-foregoing it to lengthen work days and increase social opportunities- such knowledge would be of practical importance for understanding the role of sleep in healthy emotional functioning, particular for individuals experiencing periods of increased stress and emotional distress (e.g., new parents, hospital staff, or combat troops).
A feasibility study to evaluate the use of white noise to improve sleeping conditions in an ICU setting.
