Filter by:Studies have shown that schedules that most disrupt the normal circadian rhythm have the most harmful consequences. Firefighters positive for a sleep disorder have a higher risk of depression and anxiety; they report more traffic accidents, falling asleep during driving, and worth health felt. Furthermore, some studies suggest that sleep disorders are risk factors for cardiovascular disease. This activity is responsible of a worth quality of sleep that could induce a lower effectiveness of emergency response. The consequences of this schedules on sleep and health of French firemen have never been studied.
The purpose of this study is to compare a short, behavioral treatment for insomnia with sleep monitoring to determine whether these approaches are effective in reducing insomnia and improving sleep quality among patients with heart failure (HF). This study will also examine the relationship between insomnia and cognitive functioning in HF and the effects of the behavioral treatment on cognitive functioning, self-care, distress, HF symptoms, and functional status. Participants will be randomly assigned to four-sessions of a behavioral treatment (Brief Behavioral Treatment for Insomnia; BBTI) or sleep monitoring.
Insufficient sleep and sleep irregularity (variability in sleep duration) are increasingly recognized as important contributors to glucose control and diabetes distress in type 1 diabetes (T1D). Up to 40% of adults with T1D had a sleep duration less than 6-6.5 hours per night. Diabetes distress is reported (40% prevalence) in individuals with T1D and is associated with poor glucose control. Despite findings that sleep disturbances are common in T1D, the current understanding of the effects of strategies to improve sleep on diabetes distress, and glucose control is limited. The purpose of this pilot study is to evaluate the effects of a sleep intervention on sleep duration, diabetes distress and glucose control in individuals with T1D and habitual short sleep. A randomized controlled trial in 20 adults aged 18 to 65 years with T1D is proposed. Eligible participants will be randomly assigned to a sleep intervention group or a control group. Differences between the two groups on the outcomes of sleep duration, diabetes distress and glucose control will be evaluated. Findings from this proposed pilot study will serve as the foundation for a larger clinical trial to improve sleep, reduce diabetes distress, and improve glucose control.
Sleep disorder is often a complaint from the older people. Prevalence of sleep disorder increases with aging and reaches between 20 to 45% of the people of 65 years old and more. Sleep physiologically changes with aging. Sleep can also be disturbed by other factors such as intercurrent or related chronic pathologies, environmental change (institutionalized, death of a spouse…), or some medical treatments. Regardless of interindividual variabilities, normative criteria have been defined by a meta-analysis: insomnia can be diagnosed if night wakings are more than 60min and/or if sleep latency is more than 30 minutes. Various studies have proved the major role of sleep on health and wellbeing. Sleep disorders have an impact on the quality of perception of health and on the quality of life of people and their spouse. According to the French High Health Authority recommendations, sleep diary and validated scales are the tools to use to investigate sleep disorders. Results from previous studies brought us to consider sleep complaint more specifically and adjust to the heterogeneous population of the investigator's hospital with a subjective approach. This work intends to offer a program of individualized advice to older patients with no cognitive impairment, or with a mild or moderate cognitive impairment, who complain about their sleep quality. Patients with a moderate cognitive impairment who have a caregiver at home can also join the study. The main objective of the study is to evaluate the impact of individualized care for sleep disorders on quality of sleep using the Pittsburgh Sleep Quality Index which validity was demonstrated among the elderly.
The project is aimed at identifying how the adrenergic antagonist 'carvedilol' modulates the effects of sleep deprivation in healthy volunteers. The study is a double-blind, randomized, placebo-controlled, cross-over study. Investigators will include 20 healthy volunteers who will undergo three functional magnetic resonance (fMRI) imaging sessions, one at baseline, and two after sleep deprivation (one night without sleep). The two sleep-deprivation scans are performed in a randomized order where subjects receive placebo or carvedilol, in a within-subject, cross-over study design. The following domains will be described: 1) fMRI imaging of cerebrospinal fluid (CSF) pulsations (glymphatic flow) in the human brain, performed by a combination of fMRI protocols that includes structural (T1, T2, diffusion weighted) and functional (multiband/fast imaging, spectroscopy) imaging. 2) fMRI imaging during wakefulness and sleep are determined by simultaneous electroencephalographic (EEG) recordings. 3) The effects of sleep deprivation on the fMRI derived glymphatic flow signal. 4) The effects of the adrenergic antagonist carvedilol on fMRI measurements and sleep intensity. 5) Quantification of cognitive performance before and after a nap in the MRI. Cognitive testing includes: assessments of visual attention, reaction time, paired-associative memory, working memory, emotional recognition and subjective ratings of sleepiness and mood.
To evaluate the feasibility of providing daytime bright light in the ICU in a pilot randomized controlled trial.
The goal is to collect pilot data on an adapted version of the Transdiagnostic Sleep and Circadian intervention (TranS-C), referred to as 'Fitted TranS-C'.
The aim of this study is to examine sleep architecture in refugees with PTSD. Polysomnography (PSG) will be carried out to study the occurrence of sleep disorders in patients and healthy controls.
The Nightly medical application prototype is a potential, non-invasive class I medical device. The application has the potential to combine both diagnostic and therapeutic procedures for sleep. At home, Nightly measures the user's motion during sleep and then records the sleep pattern from the received data. The obtained data are then used for the diagnosis of sleep disorders (REM and NREM sleep). Using acoustic and visual stimulation, the application has the capability to support the natural process of falling asleep, provide a better night's sleep by minimizing sleep deprivation and nightmares, while awakening the user at the appropriate moment (during light sleep).
Primary Objective: To estimate the range of improvement of NOVANUIT® triple action on sleep quality global score. Secondary Objectives: - To estimate the range of improvement of NOVANUIT® triple action on following parameters: time for getting asleep, sleep time, number of nocturnal awakening, number of nightmares, sleep quality (score from 0 to 10), and mean tiredness during the day (score from 0 to 10). - To estimate persistency of NOVANUIT® triple action effects after end of study product consumption. - To assess dependency to NOVANUIT® triple action after study product cessation. - To assess tolerance of NOVANUIT® triple action during the study.
