简要总结
The main goal of DIANA is to investigate the potential discriminative power of multimodal biomarkers in COVID adverse outcomes. The study of the neuropathological underlying mechanisms in COVID from a translational approach at: (1) the behavioural-clinical level from cognitive, emotional and functional data; (2) the brain connectome level from structural and functional imaging data; and (3) biogenetic level from blood and stool data. Moreover, the investigators will develop machine learning based predictive models of cognitive, mental health, functionality, and brain connectivity evolution in post-COVID syndrome patients.
详细描述
DIANA project is an observational, descriptive, and cross-sectional study in which participants will not be randomized. Case people (adult survivors of severe COVID-19 N=134) will compare to healthy adult controls (n=66). It is a multicentric study where all the participants will be recruited from eleven Catalan public health institutions. The participants will be assessed on cognitive, emotional and functional status. The investigators will obtain a blood sample to study inflammation, vascular risk, growth factors, angiogenesis, neurogenesis, and cellular metabolism biomarkers and genes, and a stool sample for gut microbiota study. Structural and functional MRI will be performed on a subgroup of participants 40 COVID-19 survivors and 40 healthy controls.
The objectives of the project are:
- To examine the impact of the COVID-19 illness on cognition, emotion/behavior, and functionality.
- To examine the possible affectation in brain grey and white matter and functional connectivity of severe forms COVID-19 survivors.
- To relate demographic characteristics, previous pathologies, lifestyle, baseline cerebral status, genetic polymorphism, and clinical data in acute illness with cognitive, mental health, functionality, and brain connectivity outcomes of severe forms COVID-19 survivors.
- To study the post-COVID-19 biomarkers of inflammation, vascular risk, growth factors, angiogenesis, neurogenesis, and cellular metabolism and its relationship with the cognitive, mental health, functionality, and brain connectivity outcomes of severe forms COVID-19 survivors.
- To quantify the presence of different bacterial species in the post COVID stool sample and analyze the wealth and diversity of the diverse populations. To study if these values are related to the performance of neuropsychological and behavioral tests and neuroimaging data.
-
- To develop machine learning based predictive models of cognitive, mental health, functionality and brain connectivity evolution in post COVID 19 survivors.

结局指标
主要结局
Differences between groups in auditory attention
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Auditory attention is measured with Digit Span Forward. Participants are asked to repeat numbers in the same order as read aloud by the examiner. Higher scores mean a better outcome.
Differences between groups in working memory
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Working memory is measured with Digit Span Backward. Participants are asked to repeat the numbers in the reverse order of that presented by the examiner. Higher scores mean a better outcome.
Differences between groups in language
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Language is measured with the Boston Naming Test. It consists of 60 line drawings of objects of graded difficulty, ranging from very common things to less familiar objects. The total score is the sum of correct answers. Higher scores mean a better outcome.
Differences between groups in verbal memory
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Verbal memory is measured with the Auditory Verbal Learning Test (AVLT). It is a word-learning test where five presentations of a 15-word list are given, each followed by an attempted recall. This is followed by a second 15-word interference list (list B), followed by recall of list A. Delayed recall and recognition are also tested. Higher scores mean a better outcome.
Differences between groups in visual memory
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Visual memory is measured with the Rey-Osterrieth Complex Figure (ROCF) test. The participants are asked to copy complex geometric shapes and then reproduce them from memory. A delayed recall is also tested. Higher scores mean a better outcome.
Differences between groups in psychomotor speed
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Processing speed is measured with Coding subtest of WAIS. Participants are asked to use a key to put in the appropriate symbols for a list of numbers. Higher scores mean a better outcome.
Differences between groups in perceptual reasoning
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Perceptual reasoning is measured with Matrix reasoning subtest of WAIS. Participants are asked to choose which of some possible options the missing picture is from matrix of abstract pictures. Higher scores mean a better outcome.
Differences between groups in executive function
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
A composite score is made with the z-scores of phonemic (sum of the three letters) and semantic fluency, Trail Making Test B (time) and STROOP test (color-word interference total items in 120 seconds).
Differences between groups in social cognition
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Social cognition is measured with the Reading the Mind in the Eyes Test. Participants are asked to choose the emotional state that best describes the eyes, choosing between one of four possible emotions in the 36 photographs of male and female eyes depicting emotional states. Higher scores mean a better outcome.
Differences between groups in anxiety
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Anxiety is measured with the 7-item Generalized Anxiety Disorder Scale (GAD-7), a Likert-type scale with questions ranging from "not at all" (0 points) to "nearly every day" (3 points). The maximum score is 24. Higher scores mean a worse outcome.
Differences between groups in depression
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Depression is measured with the Patient Health Questionnaire-9 (PHQ-9) which scores each of the 9 DSM-IV criteria as "not at all" (0 points) to "nearly every day" (3 points). Higher scores mean a worse outcome.
Differences between groups in Post-traumatic Stress Disorder
时间窗: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19
Post-Traumatic Stress Disorder is measured with The Post-Traumatic Stress Disorder Checklist (PCL-5), a 20-item questionnaire corresponding to the DSM-5 symptom criteria for PTSD, which scores each criterion as "not at all" (0 points) to "extremely" (4 points). The ratings of items are added together to calculate the total score (range=0-80). Higher scores mean a worse outcome.
