Active clinical trials for "Sleep Wake Disorders"

Brain health and cognitive functioning can be affected by aging. Exercise is a potentially effective method for promoting "successful brain aging" by improving cardiovascular fitness, brain function and possibly sleep quality. This project will measure the effects of exercise on brain health and attempt to develop a better way to track brain health, by measuring brain activity during sleep.

The purpose of the study is to test the effect of a sleep disorders detection and treatment program for police officers on their safety, quality of life, and job performance. The program is called Operation Healthy Sleep. We will develop and test a sleep health detection and treatment program that we aim to apply nationwide to reduce police officer fatigue and stress; enhance the ability of officers and their families to cope with police work; improve the health, safety and performance of law enforcement officers; and thereby improve public safety. Part of this program will include a questionnaire asking about about work hours and health related issues. We will then look at how these survey data relate with data on police officer safety and job performance that we are collecting through police department's databases. Sleep disorders are common and treatable, but often remain undiagnosed and untreated. Police officers work some of the most demanding schedules known, which increases their risk of sleep disorders. The public expects officers to perform flawlessly, but unrecognized sleep disorders lead to severe disruption of sleep, which significantly reduces an individual's ability to think clearly and perform well. In addition, sleep loss and sleep disruption affect personal health, increasing the risk of gastrointestinal and cardiovascular. We also know that sleep loss increases the risk of injury due to motor vehicle crashes. The goals of Operation Healthy Sleep are to improve officers' health, safety, and performance by reducing the impact of fatigue. The study will take place over two years. In the first year, half of the police officers will take part in Operation Healthy Sleep, and in the second year, the second half will participate. We will carefully select the year 1 and year 2 groups so that the data collected across the two years can be validly compared.

The purpose of this study is to determine whether a newly developed, brief cognitive behavioral intervention, relative to supportive counseling, is effective in reducing acute stress disorder (ASD) and preventing post traumatic stress disorder (PTSD) and depression.

Recruitment strategies comparing different strategies.

Objective: To determine the effect of breathing exercises on certain physiological parameters, sleep quality and vitality in the elderly. Method: In this randomized controlled, experimental study, pre and post tests were applied to 26 elderly participants in the intervention group and to 25 elderly patients in the control group. The intervention group underwent breathing exercises for 30 minutes at the same time of the day, three days a week for three months (pursed-lip breathing exercise, deep breathing exercise, coughing exercise), while no such exercise was carried out by the control group. Pittsburg Sleep Quality Index, the Subjective Vitality Scale, spirometer, sphygmomanometer and pulse oximetry device measurements were used for the collection of data. The data was evaluated with an independent sample t-test, a paired-sample t-test and a two-way repeated measures ANOVA.

Some preliminary epidemiological research conduct in China in health workers involved in the care of Covid-19 patients has shown high rates of depression (>50%), generalized anxiety disorder (>44%), insomnia (>36%) and stress symptoms (>73%), which negatively impact their well-being as well as their ability to work effectively . These rates were observed during the epidemic peak, but they can also have a long-term mental health effect, both individually, but also in a systemic manner , similar to what has been reported relative to the SARS-CoV-1 . Cognitive behavioral therapy (CBT) is recognized as an effective treatment for stress-reduction, as well as for the prevention of multiple mental health problems in at-risk individuals . Moreover, CBT has been found to be effective in brief online formats , which could make it feasible during the current Covid-19 epidemic. To our knowledge, there are no online CBT programmes targeting stress problems in health workers involved in the care of patients during the current epidemic context. The aim of our study is to evaluate the efficacy of the online CBT programme we have developped to specifically address immediate perceived stress in health workers, as well as the prevention of mental health problems at 3- and 6-months follow-up

Heart disease is a major cause of ill-health and death in adults. The risk factors for heart disease, if present in children, carry over into adult life. Childhood obesity has reached epidemic proportions in Canada and is associated with many heart disease risk factors such as high blood pressure. Another complication of obesity is obstructive sleep apnea. Sleep apnea is marked by snoring at night, pauses in breathing and low oxygen levels and occurs in up to 60% of obese children, but it is diagnosed in less than 20% of obese children. Importantly, sleep apnea in children, like obesity, is linked with high blood pressure and heart disease. Thus, children with sleep apnea who are obese are likely to have an increased risk for high blood pressure and heart disease. Currently, there is little knowledge of the extent of heart disease in obese children with sleep apnea. The best treatment for both obesity and sleep apnea is weight loss. Weight loss strategies are generally not very successful and since 75% of obese children will become obese adults, urgent treatments are needed to reduce heart disease in the long-term. Treating sleep apnea in obese children may be one of the ways to reduce heart disease. Sleep apnea can be treated with continuous positive airway pressure (CPAP), which involves wearing a mask attached to a breathing machine while asleep. It is unknown how effective CPAP is in reducing heart disease in obese children. The investigators will recruit children with sleep apnea who are obese and test for heart disease risk. The investigators will then treat these children with CPAP. After 6 months of CPAP, the investigators will repeat the tests to determine if CPAP lowers the risk for heart disease. At the end of the 6 months, those receiving CPAP will be randomized to either continue CPAP or discontinue CPAP for a 2 week period. At the end of the 2 week period the participants will repeat the tests again to determine the magnitude of the effect of CPAP. The investigators expect that CPAP treatment for sleep apnea in obese children will reduce blood pressure and lower heart disease. These results will increase awareness of the dangers of sleep apnea in obese children, which will facilitate early diagnosis and treatment, ultimately reducing heart disease long-term.

This study evaluates the effect of different dietary conducts in the nocturnal period on the postprandial metabolism and food perceptions of night workers of the Hospital of Clinics of Uberlândia, Federal University of Uberlândia.

The study aims are to: 1) optimize the Transdiagnostic Sleep and Circadian Intervention (TranS-C) for delivery to Veterans in cardiac rehabilitation, 2) test and refine the adapted TranS-C treatment manual and protocol, and 3) conduct a pilot randomized trial to establish the feasibility, acceptability, and plausibility of the intervention protocol and study procedures.

The ultimate goal of this work is to establish a method for control bleeding after tonsillectomy in awake children. Treatment of post-tonsillectomy bleeding in children typically requires general anesthesia with currently used electrocautery techniques. Micropolysaccharide hemosphere technology is a unique absorbable agent that helps clot form. These hemospheres consist of 100% purified plant starch that enhances natural clotting by concentrating blood solids such as platelets, red blood cells, and blood proteins on the particle surfaces to form a gelled matrix. This device provides painless, non-irritating control of bleeding, and has been used effectively for control of nosebleeds in awake adult patients. This device, however, has not been tested in the tonsillar fossae in children; thus, this study is performed to determine if at least 50% of children with bleeding tonsillar fossae can be spared rescue treatment with electrocautery.
