Filter by:The purpose of this study is to determine if the daily performance of a 7 step bedtime nursing protocol for hospitalized people living with dementia is feasible and if it has an effect on bedtime and daytime variables.
This study is a randomized controlled trial that will assess the effects of (1) the Family-Supportive Supervisor Behavior (FSSB) and Sleep Leadership training and (2) sleep/cognitive effectiveness feedback intervention on health and well-being among full-time employees in the Oregon National Guard, their supervisors, and their families. The interventions involving both health protection and health promotion are expected to contribute to improvements in employees' and their supervisors' sleep, risk behaviors, mental and physical health, and injury, as well as employees' and their spouse/partners' family experiences, health and well-being, and workplace outcomes.
Sleep disturbance is a significant issue in people undergoing dialysis. More than 80% of haemodialysis patients complain of difficulty sleeping. Inadequate sleep can cause poor daytime function and increased risk of motor vehicle incidents. One of the common reasons for sleep disturbance in dialysis patients is sleep apnoea. Sleep apnoea involves pauses in breathing that occur during sleep. Each pause can last only a few seconds or minutes. Severe sleep apnoea reduces oxygen supply and increases risk of heart attack and stroke, which are the leading causes of death in dialysis patients. In this project, the investigators will examine how a change of dialysis treatment might improve sleep. This project will first identify patients at risk of sleep disturbance using surveys and a subsequent sleep study. The investigators will then test different dialysis models to see the effect of dialysis treatment on sleep apnoea. The aim is to find a dialysis model that works better for patients with sleep apnoea.
The purpose of this study is to investigate whether a comprehensive group education combined with a lifestyle "activation" program that includes (a) sleep hygiene course, (b) physical activity promotion, and (c) bright light therapy, can improve both sleep quality and cognitive function among 96 community-dwelling older adults.
High fidelity simulation provide educational skills but the simulation of critical events could eventually provide anxiety among participants. The anxiety could raise before the simulation session and affect the perceived quality of sleep the night prior to the simulation session. The lack of sleep would eventually affect both participation and memorization during the simulation session. The investigators would like to investigate with a survey how much participants had their sleep affected before the simulation session.
The feasibility of using the Apnea Risk Evaluating System (ARESTM) device to take longitudinal measures of sleep parameters in asymptomatic men with prostate cancer who are about to initiate androgen deprivation therapy (ADT) will be evaluated. Study participants will complete serial questionnaires relating to sleep quality, hot flashes, and quality of life.
This study seeks to understand the physical, physiologic and biologic features that predispose a woman to the development of obstructive sleep apnea once they are exposed to the cardiopulmonary and metabolic physiological changes of pregnancy. Knowing these specific predictive factors can help identify a population at risk and guide clinicians to develop suitable targeting screening strategies.
This study evaluates the effect to a muscle stretching program combined with physical exercise versus a physical exercise program in patients with fibromyalgia.
This study aims to determine whether, compared with placebo, the nighttime administration of a intravenous dexmedetomidine is effective at inducing sleep and preventing postoperative delirium in extubated post-cardiac surgical patients.
The human eye has a dual role, which is reflected by the various photo-receptors used for vision of images and colors ,Image forming photoreceptors (IFP) and for entrainment of our "Biological clock" located in the hypothalamus through the retinal ganglions known as non-image forming photoreceptors (NIFP). The recently discovered new photo-pigment melanopsin which is sensitive to short wavelength (SWL) illumination exists in the-NIFP. The axons of the NIFP form a special nerve known as the Retino-hypothalamic-tract (RHT) that transfers the SWL signal to the biological clock resulting in suppression of pineal melatonin (MLT) production. This is the basic mechanism by which environmental light/dark cycles entrain the biological clock and transfer the message to organs, tissues and cell. The American Medical Association (AMA) issued a resolution in 2012 stating that light at night constitutes environmental pollution because it violates the daily cycles, including the waking and sleeping cycles, and suppresses the secretion of melatonin from the pineal gland at night. Results of other studies have shown that exposure to artificial light at night (ALAN) and mainly those emerging from SWL sources suppresses MLT-produced in the pineal gland. Computers, tablets, TVs, and smart-phones screens emit SWL illumination, during the day and night hours, whether as active or passive users. The results of previous studies show that, exposure to SWL-ALAN illumination suppresses MLT-secretion and disrupts sleep patterns. In order to understand better the effect of SWL-exposure emerging from screens on human behavior and health, the investigators will study the effects of SWL-exposure on the structure and quality of sleep, cognitive functioning in Continous Performance Test (CPT III), emotional state, and physiological, variables (melatonin secretion levels and body temperature) that were not tested in previous studies.
