Period of Research Internship

Starting January 2017

Additional Information

Shift work is associated with daytime sleepiness, decreased alertness, work productivity and diminishing quality of life. In addition, relations have been found between shift work and a number of negative health effects. Besides the obvious disruption of circadian function, a major factor modulating aforementioned associations is the reduction of total sleep time in shift workers. It has been shown that, even in equal sleep opportunities, total sleep time after night shifts is significantly decreased as compared to total sleep time after day shifts.
A possible solution for shift workers to increase total sleep time after a night shift may be to adhere to a ‘split-sleep’ schedule. This means creating two or more sleep opportunities in a 24-h period eventually resulting in an increased total sleep time.
However, adherence to a split-sleep schedule appears to be difficult and needs adequate coaching of a user and proper timing of the user’s sleep in order to achieve the most optimal effects. Therefore, this study attempts to explore how shift workers should be advised, whether an implemented split-sleep schedule improves sleep and consequently cognitive performance, and what the experienced benefits and burdens are of a split-sleep schedule in a user’s daily life.

Description of Research Internship

Based on a monthly shift schedule, 20 (of a total sample of 40 nurses) nurses will be advised to adapt to a split-sleep schedule. The remaining 20 nurses will not receive any advice and are asked to sleep as they would normally do. During this month, sleep will be measured via a sleep wake diary and a Philips Spectrum PRO Actiwatch. During the night shifts, sleepiness and reaction time will be evaluated 3 times (beginning of the night shift, mid night shift and close towards the end of the night shift) via the Karolinska Sleepiness Scale and the Psychomotor Vigilance Task (PVT) respectively. Working memory and risk behavior will be assessed in the morning after a nightshift with the NBACK and BART. Subjective sleep is assessed via daily completion of a sleep-wake questionnaire.

 

 

Vanaf september-oktober 2016 zijn wij, onderzoekers aan de Universiteit van Bordeaux, Frankrijk, op zoek naar gemotiveerde Bachelor of Master studenten Neuroscience, Psychologie of soortgelijke studierichtingen die bij ons een stage
willen lopen.

We runnen twee onderzoeksprojecten waarbij onderzocht wordt hoe slaapproblemen leiden tot emotionele en cognitieve problemen overdag, door middel van beeldvormende technieken als EEG, fMRI en een rijsimulator. De onderzoeksgroep wordt geleid door Dr. Ellemarije Altena en is gevestigd in de SANPSY afdeling van het Pellegrin ziekenhuis in Bordeaux. We zoeken gemotiveerde stagiairs, die bij ons alle aspecten van een neurowetenschappelijk onderzoeksproject kunnen leren. Franse spreekvaardigheid is een voorwaarde, met de teamleider ook in het Nederlands of Engels worden gesproken. Duur en vergoeding van stage in overleg. Ben je geïnteresseerd, neem contact met ons op: tel. +33 557 82 11 03 of via neurosci.ealtena@gmail.com of yannick.daviaux@u-bordeaux.fr.
