Active clinical trials for "Sleep Disorders, Circadian Rhythm"

The purpose of this study is to test the hypothesis that ingestion of the wake-inhibiting drug suvorexant 30 minutes prior to daytime sleep initiation in individuals working overnight shifts will significantly improve both objective (total sleep time, sleep efficiency, wake after sleep onset) and subjective (sleep quality) measures of daytime sleep.

Brain Entrainment Technology (BET), also known as Binaural Beat Technology (BBT); is an auditory-neurophysiologic technique which uses auditory tones (often embedded in music, nature sounds or white noise) dichotically via stereo headphones to manipulate brainwave activity in turn affecting the listener's mental, physical and/or emotional state. Although this technology is widely marketed to the general public and can be found free in on the internet, only a hand full of scientific studies have shown its efficacy. This study is a follow-on study to the "Sound Mind Warrior (SMW) Study" (ClinicalTrials.gov [NCT02328690]) conducted 2012-2015 which assessed the efficacy of the technology (in the "theta" brainwave frequency) on the cardiovascular stress response in a group of service members with complaint of chronic stress. This study will now assess BET (in the "delta" brainwave frequency) on sleep quality in a population of military healthcare beneficiaries with complaint of poor sleep quality.

Sleep has a number of health benefits, including memory and learning, vitality and energy as well as high quality of life levels. Lack of sleep impairs judgment, impacts longevity and safety, and increases the risk of a number of diseases including obesity, hypertension, heart disease, diabetes, mood disorders, and impaired immune function. In addition lack of sleep or disturbance of normal sleep cycle could have a major impact on people's lives and working performance such as driving. Daily sleepiness is a problem concerning professions with a non-fixed schedule. Specifically, professional long-haul drivers confront sleepiness problems and in combination with fatigue, they are prone to driving accidents and other incidents. Sleep quality and quantity are closed related to fatigue which is one of the most common reasons for driving and working accidents. In recent years, car accidents involving professional drives have increased significantly. The main reasons for those accidents were fatigue and sleepiness due to long hours of driving or difficult working conditions according to the recent European report (Driver Fatigue in European Road Transport - etf-europe.org). Lifestyle Medicine addresses health risk factors in primary, secondary, and tertiary prevention of developing disease rather than on acute care and reacting to illness, injury, and disease. Lifestyle Medicine strategies targeting modifiable risk factors, such as diet, sleep, stress, and physical activity. By applying those regimes the investigators could improve physical and mental health levels that can affect the quality of sleep, reducing daily sleepiness and fatigue, in professional drivers operating coaches and trucks. Any intervention that could improve alertness and reduce fatigue and sleepiness in those people, will automatically improve safety, reduce driving accidents and save lives and resources.

EuRhythDia II is a multicenter, randomized, double-blind controlled study. The rationale of EuRhythdia is to explore the effects of 12 weeks of timed melatonin treatment on circadian rhythm, metabolic control and cardiovascular function in night shift workers. The 12 weeks of intervention will be followed by 12 weeks of washing out.

Police officers work some of the most demanding schedules known, which increases their risk of sleep deprivation and sleep disorders. The need to work frequent overnight shifts and long work weeks leads to acute and chronic partial sleep deprivation as well as misalignment of circadian phase. The public expects officers to perform flawlessly, but sleep deprivation and unrecognized sleep disorders significantly degrade cognition, alertness, reaction time and performance. In addition, both acute and chronic sleep deprivation adversely affect personal health, increasing the risk of gastrointestinal and heart disease, impairing glucose metabolism, and substantially increasing the risk of injury due to motor vehicle crashes. We propose to conduct a randomized, prospective study of the effect on the safety, health, and performance of a police department of a Comprehensive Police Fatigue Management Program (CPFMP) consisting of the following interventions: identification and treatment of police with sleep disorders; caffeine re-education; and initiation of a sleep, health and safety educational program. These interventions were chosen because we believe them most likely to lead to measurable improvements on work hours, health, safety, and job performance, and because they are cost effective. The success of the CPFMP will be assessed through an experimental comparison with a standard treatment group that will receive sleep education in the absence of any accompanying interventions. The overall goal of our team will be sleep health detection and treatment program that can be disseminated to practitioners, policymakers and researchers nationwide to reduce police officer fatigue and stress; enhance the ability of officers to cope with shift schedules; improve the health, safety and performance of law enforcement officers; and thereby improve public safety.

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.

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.

Sustainable Methods, Algorithms, and Research Tools for Delivering Optimal Care Study (SMART DOCS) was designed to develop and evaluate a new approach (patient-centered outcomes and coordinated-care management [PCCM]) for the diagnosis and treatment of sleep disorders. Specialized and pertinent information and resources regarding sleep disorder management were developed and made available through an online portal, allowing patients to make informed health care decisions, and providers to assist patients in achieving what they feel are the most important goals regarding their care. Half of participants were randomized into the conventional diagnosis and treatment (CONV) arm and the other half into the patient-centered outcomes and coordinated-care management (PCCM) arm. Validated objective and subjective assessment measures were administered at intervals throughout a 13 month participation period in both the CONV and PCCM arms to determine whether the new PCCM approach for sleep medicine results in increased patient satisfaction, quality of care, and improved health outcomes. Qualifying participants were 18 years of age or older and presenting with a new sleep disorder. Patients received no monetary compensation.

Circadian rhythm disorders are a class of sleep disorders characterized by misalignment between the timing of sleep and the timing of rhythms driven by the biological clock. Light therapy can effectively treat these disorders, but the intensity and duration of light exposure required to do so has limited its practical use. In this study the investigators will test whether pre-exposure to dim light may enhance the response of the circadian system to light therapy. If so, this could result in shorter treatments that would have greater practical applications.

Particulate matter exposure during smoke inhalation provokes inflammatory immune responses in people exposed to burning biomass including fire fighters and civilians. Persistent occupational exposure to particulate matter represents a unique hazard for firefighters, underpinning a burgeoning research area. This trial will evaluate the effects of sleep deprivation and circadian rhythm disruption on the inflammatory response to woodsmoke associated particulate matter exposure. Participants will undergo 2 experimental trials in a randomized cross-over design. Participants will have either an 8-hour sleep opportunity or a 4-hour sleep opportunity prior to reporting to lab for a 45 minute simulated firefighting trial (wood smoke associated particulate matter filtered to 2.5 um at a concentration of 250 ug/m^3, while exercising at a moderate intensity). The effects of sleep restriction and simulated firefighting will be measured.
