Active clinical trials for "Sleep Wake Disorders"

Monitoring patients with chronic, inflammatory airways disease particularly in the early stages is hampered by the relative insensitivity of current outcome measures to detect subtle changes. Multiple breath washout is a potential sensitive test that is a useful readout of disease at these early stages but it lacks standardisation and knowledge of variability with reference to standard lung function measures. This is a Cross sectional and longitudinal observation study. The hypothesis is that multiple breath washout-derived indices will provide a robust signal of gas mixing inhomogeneity, correlating with conventional measures of airway disease severity. Multiple breath washout performed on different devices will generate indices which correlate but differ in value.

There is an unmet demand for the evaluation of nocturnal hypoventilation in children with NMD. An ambulatory screening tool that can reliably facilitate timely diagnosis and treatment in these children would be invaluable. If an ambulatory, at home, tcCO2 monitoring device is shown to be diagnostically accurate, sleep physicians would be able to triage children on existing waiting lists and optimize screening of nocturnal hypoventilation as recommended by international guidelines.

A lot of effort has already been put into the development of smaller, wearable and more user-friendly devices to monitor seizures in patients with epilepsy. The investigators hypothesize that a wearable EEG ( in combination with additional non-EEG biosignals (motion, ECG, EMG, respiration, temperature,...) derived from Byteflies Sensor Dot and new medical patches (Plug 'n Patch system), will be able to objectively detect epileptic seizures and monitor sleep in the hospital and home environment for specific types of childhood epilepsy. The accuracy of seizure detection and sleep monitoring by the wearable miniature EEG device in combination with other (autonomic) biosignals (full PnP system) will be compared with the golden standard video-EEG and seizure and sleep diaries filled-out by the participants.

Recently, an association between active inflammatory bowel disease (IBD) and poor sleep quality has been proposed; however, the causal relationship has not yet been established. This study aimed to investigate prevalence of poor sleep quality in IBD and association with disease activity by subjective and objective measures. Prospective observational study is conducted with expected sample size of 100 patients. Participants are classified into active and inactive disease status according to standard IBD severity assessment measures. Demographic data, disease activity, quality of life, sleep questionnaire (validated PSQI questionaire), and seven-day sleep data acquired from ambulatory wrist actigraphy were obtained. Association between sleep quality and disease activity will be analyzed.

A prospective cohort study to evaluate the association between various triggers encountered in daily life and induction of atrial arrhythmias (atrial fibrillation, atrial flutter, atrial tachycardia and premature atrial contractions) with the use of long-term monitoring devices. The collected data of personalized triggers and risk factors will be used to define the individual phenotype of atrial arrhythmia.

Include participants who intend to practice Ramadan fasting and accept to complete the three part of the study .

The primary objective of the Nuvigil/Provigil Pregnancy Registry is to characterize the pregnancy and fetal outcomes associated with Nuvigil and Provigil exposure during pregnancy.

The purpose of this study is to test whether shifts in the timing of the biological clock to a later hour (phase delay shifts of the human circadian system) can be produced in response to four successive evenings of light exposure, and whether that phase shift will result in greater evening alertness and greater nighttime sleep efficiency. Three different light sources will be compared: 1) standard fluorescent light; 2) blue-enriched light; 3) incandescent fluorescent light.

This study will examine how depression, anxiety, and migraine run in families. It will help in defining the risk factors for physical, mental, and health problems-as well as define ways that those problems may be prevented and treated. A broad range of ages among family members will be included to evaluate the patterns of how these disorders are expressed throughout people's lives. Children of all ages will be included, and those ages 8 to 17 will be interviewed directly. Assessments will be collected through criteria of the Diagnostic and Statistical Manual of Mental Disorders IV as well as the spectrum, or range, of mood disorders and co-existing conditions. A member of the study team will visit the participants at home or will do an interview by telephone. Participation will take approximately 3 to 4 hours. Children will complete questionnaires given by the research team as well as questionnaires that they will do by themselves. The questions will pertain to the children's health, including physical and mental health and medical history, social relationships, problems, skills, and ways of dealing with important or stressful issues in their lives. These questionnaires will take up to 1 hour to complete. Health history gathered from adult participants will pertain to height, weight, exercise, and general function. Women will be asked about the use of oral contraceptives, estrogen, and progesterone. In addition, there will be questionnaires on personality and temperamental traits, that is, behavior and impulsiveness. Questions will also involve social intuition, family and other environmental factors, general functioning, and basic demographics such as ethnicity, race, socioeconomic status, marital status, education level, and employment history. Families enrolled in this phase of the research will be invited to participate in the next phase. There would be follow-up to evaluate the development of mood disorders, subtypes, and syndromes across the lifespan.

The current study is a prospective blinded study to collect data regarding the performance of the WP device in detecting sleep disorders. For that purpose, the WP with finger probe and chest sensor will be worn by the subject simultaneous to PSG in a sleep study at the clinical sleep lab. A PSG system will be recording the PSG data.
