Insufficient sleep has both health and safety risks, but currently there are no quick, accurate and inexpensive ways to measure sleep deficiency. The current study aims to use a cutting-edge technology, small molecule analysis (e.g. metabolomics), to detect compounds in breath that reliably change with sleep-wake state and those whose levels vary by time of day.
NCT02978053
This project examines 1) the effects of appropriately timed bright light on adaptation (in terms of sleep and sleepiness) to three consecutive night shifts; and 2) the effects of such bright light on re-adaptation (in terms of sleep and sleepiness) to a day-oriented schedule after the night shift period.
NCT03087435
It is necessary and important to design tools to evaluate a central aspect of medical residents formation. The research group has been working with resident well-being since a few years in order to improve the global quality of the education and working environment. The investigators present a plan to develop and validate a tool to assess residents well-being. A tool designed with this characteristics would be of much importance to monitored as a security event, managed and actively promoted well being in residents.
NCT03153917
Nonstandard time-schedules work are widespread in the world of work. Shift and night work have been shown to be responsible for a desynchronization of biological rhythms, associated with melatonin secretion impairment and sleep disturbances. However, while health consequences of night and shift work are widely recognized and represent a major public health concern (High Authority of Health 2012 Recommendations and National Agency for Public Health Food, Environment and Work 2016 Report), the mechanisms by which the circadian system is affected by shift work remain poorly understood. Indeed most of the studies in the fields are cross-sectional, based on few blood or urinary samples in a single work position, in workers whose shift work patterns are often misidentified and heterogeneous. Moreover, few studies have assessed melatonin secretion alterations in relation to objective sleep measurement (actigraphy). The aim of this study is to assess the dynamics of melatonin secretion adaptation in 12-hour shift work and to correlate these data to sleep-wake cycle recording.

Firefighters work some of the most demanding schedules known under highly stressful and demanding conditions. The need to work frequent extended shifts and long work weeks leads to acute and chronic partial sleep deprivation as well as misalignment of circadian phase. Sleep disorders are common, costly, and treatable, but often remain undiagnosed and untreated and it is likely that a significant proportion of firefighters suffer from undiagnosed sleep disorders which will further impair their sleep and exacerbate fatigue.In the current proposal, we aim to address the health, performance and safety issues related to fatigue in firefighters and test the effectiveness of a Comprehensive Firefighter Fatigue Management Program (CFFMP) that we have termed 'Operation Healthy Sleep.'
NCT01264913
The overall goal of the present application is to test the hypothesis that shift workers, who are chronically exposed to circadian misalignment and sleep loss, have a higher cardio-metabolic risk than day workers, and that the accumulated sleep debt and the degree of circadian misalignment both predict their elevated cardio-metabolic risk.
NCT00078312
The primary objective of this study is to evaluate the safety and tolerability of Armodafinil (CEP-10953) administered on a flexible-dosage regimen of 100 to 250 mg/day for up to 12 months to patients with excessive sleepiness associated with a current diagnosis of narcolepsy, obstructive sleep apnea/hypopnea syndrome (OSAHS)(regular users of nasal continuous positive airway pressure \[nCPAP\] therapy), or chronic shift work sleep disorder (SWSD).
NCT00786266
The purpose of this study is to determine if a modified version of the Sleep Enhancement Fatigue Reduction Training (SEFRT) system can improve sleep and health-related symptoms and quality of life in shiftwork-naive new nurse graduates.
