Filter by:This study aimed to investigate the effect of chronic neck pain on sleep quality and to determine the factors that may be related to sleep disturbance.
Recent studies in animal models have suggested a critical role for cerebrospinal fluid and Interstitial fluid flux through cerebral parenchyma for removal of byproducts of cellular metabolism and hence in maintaining the health of the brain. This effect is modulated during sleep, suggesting a potentially important mechanism for sleep to maintain both acute homeostasis and long-term cerebral health. The central goal of these studies is to develop a sensitive MRI biomarker of cerebral conformational changes during sleep. This exploratory work aims to establish the sensitivity and reproducibility of MRI as a non-invasive neuroimaging assessment of cerebral changes during natural sleep and sedation.
This study evaluates the use of actigraphy-derived measures to improve prognostication in patients with advanced cancer.
Wireless wearable devices (WWD) have been shown to be an effective means to measure patient activity and sleep-wake cycles in the ICU. However, no current studies involving WWD have demonstrated the ability of these devices to measure adverse outcomes, including delirium in critically ill patients. This study is unique because the investigators will implement monitoring with the WWD prior to extubation in the ICU to correctly measure first mobilization, as well as capture quality of sleep and episodes of delirium for the first five postoperative days.
This study will investigate the effect of two dietary patterns on sleep outcomes and measures of reported appetite. Participants will be given two different diets on two separate stays.
The study is divided into two stages, the purposes of the first stage are (1) to examine the feasibility and simplicity of the operation of bathtub machine for nurse aides; (2) to examine the safety and comfortability of the bathtub machine from the perspectives of the nurse aides. The purposes of the second stage are (1) to understand the experiences of nurse aides and the elderly with disability by using the bathtub machine(which has edde massage function); (2) to evaluate the effectiveness of using the bathtub machine on the sleep quality and body temperature in the elderly with disability.
To further understanding of the relationship between sleep and memory the investigators will address and attempt to answer three questions, (1) how memories evolve across wake and sleep, (2) how different aspects of this memory evolution are reflected both behaviorally and in the EEG signal, and (3) what stages and features of sleep affect memory evolution. Together, these studies will provide a greater breadth and depth of knowledge concerning sleep's role in memory consolidation. Such knowledge would be of practical importance for educational practices, whether in schools, on the job, or in the military, and would also provide valuable information to the fields of sleep medicine and psychiatry, where interactions between sleep disorders and cognitive functioning are of great importance.
Sleep deprivation produces changes including alteration of mood, irritability, fatigue, less focus and disorientation, also perceptive distortions, visual hallucinations and considering tasks harder and less pleasant. In resident physicians, these alterations have been shown to affect their work performance. Naps have proved to improve arousal and attention, alertness and performance. Those longer than 90 minutes promote a learning process similar to that occurring in REM sleep. Therefore a nap schedule could improve the decision making of residents during their working hours.
The project will contribute with new knowledge concerning how aspects of the physical work environment (lighting conditions) can be arranged to facilitate the workers' adaptation to night work. This is important given the reported adverse consequences of shift work for performance, safety, and health. The project involves a series of three experimental, laboratory based shift work simulation studies. The aim is to investigate how different lighting conditions (intensities and colour temperature), administered through light emitting diode (LED) based bright light integrated standard room lighting, affects adaptation to three consecutive simulated night shifts and re adaptation to a day oriented schedule on measures of alertness, cognitive performance, sleep and circadian rhythm. The proposed project examines the effects of interventions that can be applied in naturalistic settings and will be based on new laboratory infrastructure available at the laboratories situated in the Faculty of Psychology, University of Bergen.
The First 1000 Days (conception to age 2) is a crucial period for the development and prevention of obesity and its adverse consequences in mother-child pairs and their families. The overall aim of the First 1000 Days program is to work across early-life systems to prevent obesity, promote healthy routines and behaviors, address social determinants of health, and reduce health disparities among vulnerable children and families at community health centers in the Boston, MA area. The study aims to simultaneously implement and evaluate an obesity prevention program across early life systems to reduce the prevalence of obesity risk factors within racial/ethnic minority families, close the gap in maternal-child health disparities, and assess and address social determinants of health.
