简要总结
There is a lack of complex studies which could establish the association between genetic circadian factors with the features and short-term outcomes of ischemic stroke, as well as the effects of various auxiliary therapies for circadian rhythm modulation for neuroplasticity enhancement and improvement of short-term outcomes in ischemic stroke.
The main research hypothesis is that circadian factors influence the recovery from ischemic stroke via sleep-mediated regulation of synaptic plasticity.
The project aims at the investigation of the influence of combined melatonin therapy and blue light exposure on molecular circadian biomarkers, sleep characteristics, neuroplasticity markers and stroke outcome in acute stroke patients.
This study is a prospective, interventional, randomized placebo-controlled trial.
详细描述
The study will investigate the influence of combined blue light exposure and melatonin therapy on molecular biomarkers of circadian rhythms, sleep characteristics and stroke outcome in acute stroke patients This study is designed as a prospective study in acute stroke patients (approx 80 patients) admitted to the Stroke Unit. After initial assessment, the participants will be randomly assigned in 4 groups (the treatment or control) with approx.20 participants in each group.
In all participants, the following parameters will be assessed: medical records, stroke characteristics, sleep characteristics, cardiovascular circadian rhythms and blood samples for the evaluation of circadian molecular biomarkers at baseline and 14 days after inclusion. Stroke outcomes will be reassessed at 3-month follow-up.
The following associations will be assessed:
- the role of blue light exposure and melatonin treatment for stroke outcome
- the role of blue light exposure and melatonin treatment in the modulation of sleep parameters in acute stroke
- the association of molecular biomarkers of circadian rhythms with stroke outcome (the difference in neurological and functional deficit from admission to 14 and 90 days after study inclusion), with stroke characteristics (stroke subtype and neuroimaging stroke parameters, routine protocol) and with sleep characteristics.
- the association of sleep characteristics with stroke outcome (the difference in neurological and functional deficit from admission to 14 and 90 days after stroke) and with stroke characteristics (stroke subtype and neuroimaging stroke parameters, routine protocol).

时间窗: From baseline to 14 days after treatment initiation
Rivermead Mobility Index (a standardized scale used to assess mobility in patients with neurological deficits, a maximum of 15 points is possible; higher scores indicate better mobility performance)
Stroke-related disability assessed by the change in Barthel Index from baseline to 14 days after treatment initiation
时间窗: From baseline to 14 days after treatment initiation
Barthel Index (a common scale used to measure performance in activities of daily living, 0-100 scores, higher scores define better performance)
Stroke-related disability assessed by the change in modified Rankin scale from baseline to 14 days after treatment initiation
时间窗: From baseline to 14 days after treatment initiation
