Filter by:This is a double-blind, single center, parallel group, placebo and active comparator, controlled study to characterize the wake promoting effects of single doses of SPD489 in healthy adult male undergoing acute sleep deprivation.
The purpose of this study is to determine if sleep deprivation results in increased esophageal acid exposure in healthy controls and gastroesophageal reflux disease (GERD) patients.
Sleep deprivation in healthy volunteers is associated with immune dysfunction. This adverse effect of sleep deprivation likely occurs in patients suffering from acute injury and critical illness requiring intensive care unit (ICU) admission. Studies have demonstrated that sleep in ICU patients is highly abnormal. The global hypothesis for this proposal is that a strategy to promote sleep in ICU patients will increase time in rapid eye movement (REM) and slow wave sleep (SWS). This three phase proposal examines the feasibility of a sleep promotion strategy for injured and critically ill patients in the ICU. Phase I (Development and Training): Develop an intervention manual for sleep promotion, Sleep Enhancement Program (SEP), and train ICU staff. Phase II (Validation and Safety): Implement SEP and test for protocol fidelity and safety. Phase III (Efficacy): Conduct a pilot trail to determine efficacy of SEP to improve SWS in ICU patients.
The purpose of this study is to understand patients' neurocognitive performance shortly after discharge from the Medical Intensive Care Unit (MICU) and the potential effect of sleep quality in the MICU on those neurocognitive outcomes. The investigators hypothesize that post-ICU neurocognitive function and patient overall ICU sleep experience will improve through a pre-existing MICU sleep improvement initiative.
The overall goal of this research is to elucidate how environmental, healthcare, and patient-level factors and patients' level of perceived control impact sleep duration and quality in hospitalized older patients and to assess whether better in-hospital sleep is associated with improved physical activity and health outcomes. We hypothesize that environment, healthcare disruptions and patient symptoms will be significantly associated with objective and subjective sleep duration and sleep quality in hospitalized older patients. We also hypothesize that a high level of perceived control will be associated with improved sleep duration and quality in hospitalized older patients. We further hypothesize that shorter sleep duration and quality in hospitalized older adults will be associated with adverse health outcomes, namely higher blood pressure and blood sugar.
The purpose of this study is to determine whether reducing intern work hours and eliminating extended shifts in the intensive care unit will reduce prescribing errors and improve intern well-being.
Evidence that shortened period of sleep could be a risk factor for weight gain and obesity has grown over the past decade. Concurrent with the obesity epidemic, numerous studies have reported a parallel epidemic of chronic sleep deprivation. Sleep is important in maintaining energy balance (i.e. acute sleep deprivation impact the normal secretion of ghrelin and decreases leptin plasma levels). Surprisingly, in humans, there is no direct evidence that a shortened night has direct effect on energy metabolism during the following day. This study is set up to determine whether a partial sleep deprivation night has an impact on appetite and food energy intake and, concomitantly, on physical activity, during the following day.
This study will test the feasibility and effectiveness of protected time for physicians in training during 30 hour shifts in a medical intensive care unit. The primary outcome will be fatigue. Secondary outcomes include the amount slept while on call, depression, and burnout.
Observational and epidemiological studies have found a link between obesity and short sleep duration with the prevalence of both increasing in the past decades. At this time, it is unknown whether short sleep is a cause of obesity and how short sleep would lead to obesity. Some studies associate short sleep with increased levels of hormone that stimulate appetite. This study will examine how food intake and energy expenditure can be modified by sleep duration as a means of understanding a potential causal pathway.
Long and unorthodox working hours (e.g. 24 hours or 23pm-07am shifts for doctors and nurses respectively) combined with sleep deprivation, may affect cognitive functions such as response time and concentration. These parameters may be tested using a driving simulator. Apart from the obvious consequences of driving skills impairment for the medical personal, it may serve as a quality assessment tool in evaluating the impact of workload and sleep deprivation on medical staff's function. This study aims to assess the effect of work load and sleep deprivation on medical staff's driving skills.
