Filter by:Investigators will evaluate the efficacy of postoperative oral suvorexant treatment on nighttime wakefulness after persistent sleep onset (WASO) among adult cardiac surgical patients recovering in the cardiac intensive care unit (ICU). The study include patients ≥ 60 years old undergoing coronary artery bypass graft surgery (CABG), with or without valve surgery (aortic or mitral). Patients will receive either oral suvorexant or placebo for 7 nights starting the night after extubation. The primary hypothesis is that suvorexant compared with placebo decreases WASO, as measured by a specialized electroencephalogram (EEG), the SedLine monitor, during the first night in the cardiac ICU. Investigators will also assess total sleep time (TST), time to sleep onset (TSO), and postoperative delirium and delirium-free days.
This study evaluates the acceptability, feasibility, and efficacy of an intervention using wearable sensors and a mHealth application, SOmNI, to promote sleep for adolescents. The investigators hypothesize that a behavioural intervention delivered through a mobile app will be a cost-effective and accessible method of engaging adolescents in the self-management of sleep behaviours. Participants will be randomized to either the SOmNI Intervention group or the Control group. Participants receiving the SOmNI app will attempt to incrementally move their school night bedtime earlier in the evening.
A quasi-experimental design where internal medicine residents in a high complexity hospital were assessed after a 24-hour shift for cognitive impairment by a trained neurologist.
The purpose of this study is to evaluate the efficacy of later school start times in increasing student sleep, and examine the association between later start times and physical activity, screen time, and commute time. Subjects will wear a FitBit activity tracker wristband for two separate 3-month periods (the year before and the year after the Francis Parker High School start time change in the Fall of 2020) and be advised to wear it as much as possible, especially while sleeping or performing physical activity. At the beginning and end of each study period (at 4 occasions), subjects will fill out a few short, non-invasive surveys about their commute, after-school activities, sleepiness, and preferences for morning or evening, and perform the non-invasive psychomotor vigilance test to measure alertness.
Investigators will enroll up to 20 participants from 3 Children's Hospital of Philadelphia (CHOP) primary care locations. The primary objective is to determine the whether the Sleep Well! behavioral sleep intervention is feasible to be implemented in primary care offices and acceptable to families. The direction and magnitude of change in child sleep from pre-intervention to post-intervention will also be examined.
The study is a case-controlled observational trial. Forty patients will be divided into 2 groups (good or poor sleepers) depending on their first postoperative night Bispectral index data. Firstly, this study aims to characterise the lung microbiota in patients treated with thyroid surgery. Secondly, it aims to evaluate microbiota and its influence on plasma kynurenine.
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.
