Filter by:This investigation will be a randomized interventional prospective quality improvement study. Patients undergoing plastic surgery with flap procedures (n =123) will be randomized to evaluate the effect of the implementation bundle for sleep quality improvement in the surgical intensive care unit (SICU). Roughly one half of the patients (n =62) will be randomized to the intervention group. This group will receive the intervention bundle which consists of providing ear plugs and eye masks to patients and their family members. Roughly one half of the patients (n =62) will be randomized to the control group. This group will receive "usual care", which does not include ear plugs or eye masks and lacks specified times for laboratory draws and imaging studies. For each of the two groups, the investigators will collect Richards-Campbell Sleep Questionnaire (RCSQ) scores, Confusion Assessment Method for the ICU (CAM-ICU) scores, and modified Family Satisfaction in the Intensive Care Unit (FS-ICU) scores. The investigators will administer the RCSQ to these patients following every night they spend in the SICU and the FS-ICU questionnaire immediately prior to their discharge from the ICU.
This study seeks to examine a novel interpersonal target; namely, parent-teen conversations about youth health behavior change. The rationale is that parents have profound impacts on teen risk and vulnerability. Yet parents receive minimal training in the elements of conversations that optimally inspire their children toward engaging in healthy behaviors. A theoretically grounded and reliable taxonomy of behavior change techniques (BCTs) will be used as a basis for scientifically deriving the conversational elements, or micro-mechanisms, that reduce parent-teen conflict and facilitate upward spirals of healthful behavior change. This proposal builds on pilot data from a recently completed NICHD-funded R01 in which a sleep treatment improved sleep and reduced risk on selected outcomes in youth. While sleep-related health behaviors will be the focus of this R21, the research is designed to be relevant to a broad range of health behavior change. As part of an Administrative Supplement to the R21 awarded in Fall, 2019, two changes are made. First, measures of psychophysiology have been added to the Hot Topics Task. Second, an independent sample of teens who are healthy sleepers (n = 20), and their parents, will be tested on the protocol twice, 9 weeks apart. This comparison group is included to control for the passage of time and for completing the protocol twice. They do not receive an intervention.
Our research question is: Are changes in sleep duration that occur naturally over school holidays associated with changes in blood pressure (BP) in sleep-deprived adolescents? In this study, the investigators will take advantage of changes in sleep duration that occur during school holidays in adolescents who are sleep deprived (>6 months' history of sleeping <8 hours per night during school term). The investigators will monitor the changes in ambulatory BP and sleep duration over a period of 3 weeks which consist of a week at school, followed by a week of holiday when natural sleep extension takes place, and then another week of school after the holiday. Sleep-wake cycle will be recorded throughout the whole study period with actigraphy and sleep diary. Twenty-four hour ambulatory BP monitoring will be performed on the same weekday during each study week, when salivary cortisol will also be collected. The primary outcome measure is the difference in ambulatory BP parameters between school term and holiday. A control group without sleep deprivation (history of sleeping >8 hours per night) will also be studied concurrently It is hypothesized that changes in sleep duration are negatively associated with changes in BP. If this study confirms our hypothesis, sleep extension can be used as a relatively inexpensive and simple behavioural intervention in the management and prevention of blood pressure abnormalities. More importantly positive results from this project will provide background information on which government and local school policy can be based and altered for the betterment of our youths.
Nocturia is prevalent in older adults and it vastly reduces quality of life. Yet its treatment remains inadequate because its causes are not well understood, especially nocturnal polyuria or increased urine production at night. This study, which builds on the investigators' ongoing research, would be the first of its kind to explore the role of sleep in nighttime urine production. The findings will contribute important knowledge to guide development of better targeted and more effective therapy for this prevalent and morbid condition.
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.
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.
