Healthy minds from 0-100 years: Optimising the use of European brain imaging cohorts


Lifebrain gender equity report (R)

The management in coordination with the Safety Board (SB) team will ensure and monitor that the consortium’s policy regarding gender issues is correctly implemented, including the awareness and sensitisation programmes.

Communication management routines and infrastructure implemented

Establish routines for communication amongst consortium partners including the exchange of information and materials, while ensuring maintenance the EC Grant Agreement and Consortium Agreement. Provide assistance and advice to partners regarding administrative matters, and to ensure compliance with EC rules including the communication with and reporting to the EC on behalf of the consortium

Multi-modal MRI-data processing stream which allows for a state-of-the art central integration of data across sites

A standardized analysis stream will be developed that all data can be run through, with special focus put on neuroimaging.

Enrichment of existing cohorts by home collection of DBS to be analysed across WP4 tasks 2-6

Kits for home collection of DBS will be sent to participants in all samples, which will send them back to Vitas for analyses, with the aim of getting 2000 samples

Lifebrain conference in Berlin

Organization and completion of conference

Risk and protective factors for cognitive and mental health in broader epidemiological samples

Divided into two parts: A) Using multivariate regression analysis and multilevel/hierarchical models, existing European Research Infrastructure Consortia (ERICs, SHARE) will be leveraged to analyze i) how cognitive performance and risks of depression and anxiety differ by socioeconomic status (SES), gender and age, ii) how these patterns differ across regions/countries, and iii) the extent to which the cognitive outcomes are associated with differences in health and everyday functioning. B) Based on results from task A, population-covering administrative register data from Scandinavian countries will be used to corroborate the real-world relevance of these findings

Online/mobile tools for stakeholder engagement conceptualized and developed

Prepare tools and platform for stakeholder engagement. Social media, like twitter, will be one area of interest. Also web-based questionnaires, tests and engagement tools will be considered, and possibly developed

Tool for post hoc harmonization of MRI data across sites, to allow integration of data from different scanners/sites

Implement and test a novel procedure to correct images for scanner-specific differences in tissue contrast and intensity non-uniformity.

Enrichment of existing cohorts by administration of buccal swabs for epigenetic analyses across WP4 tasks 2-6

Coordination of the sample collection, laboratory experiments and bioinformatic processing of the data for analysis in WP4

Input to the Dissemination, Exploitation and Communication(DEC) plan (T5.1)

Prepare tools and platform for stakeholder engagement, ensure that WP1 is fully aligned with WP5s DEC plan

DBS assays for relevant biomarkers for data enrichment

Develop and validate new additional biomarkers on DBS tailored for the Lifebrain project

DEC Strategy, Operative Plan and SOPs for the Lifebrain project

Details the communication and dissemination strategy including stakeholder engagement practices for targeting different audiences and resulting in the definition of a detailed activity plan for phase one (M1-30). The operative part of the DEC Plan will be updated based on project activities and experiences. Standard operating procedures (SOPs) for publications, participation in conferences and exploitation will be annexed to this plan

Data storage and processing system to share data, manage data access and integrated analysis

Establish an international image sharing, storage and processing platform for management of neuroimaging and harmonized target variables

Online platform for collection of questionnaire and test data for data enrichment

The implementation will include three major steps: (a) identifying and operationalizing (e.g., selecting standard and custom questionnaires, or neuropsychological tests) the variables to be assessed; (b) translating the instructions, questionnaires/test items or identifying language-specific version for standard questionnaires/tests); (c) implementing a OS independent internet browser-based platform which allows for data collection and transfer of data using secure file transfer protocol.

Exploitation and IP management strategy - I

An integrated IP and exploitation strategy will be defined and implemented along with innovative communication channels developed

List of relevant stakeholders for project engagement

Identify and invite research participant groups, patient groups, clinicians and policy makers that will have an interest in the project and that should be taken into consideration

Enrichment of existing cohorts by online data collection

Develop and apply a tool for online collection of data to enrich available database, allowing Lifebrain databases to attain data which not all sites have available and data on new variables, and by doing so optimize the utilization of the existing data

DEC strategy and Operative plan – Update

Update strategy report conducted under D5.1

Financial and legal management routines implemented

To establish a robust management structure to ensure that the objectives of the project are met within agreed budget and timeframe, granting that the administrative, legal and ethical aspects are fulfilled by each partner and ensuring that allocated finances are appropriately managed and reported, carrying out adequate quality control of the work performed and of the deliverables;

Data harmonization guidelines and standardized data management/processing protocol across sites

We will develop and implement harmonization protocols, i.e. develop technical and semantic data standards, and quality protocols to unify and bridge the different coding standards of target variables between sites

GWAS data and harmonization of genetic data across samples for genetic analyses across WP4 tasks 2-6

This will include re-calling of genotypes, from existing genome-wide SNP genotype data, quality checking, imputation, determination of population substructure, and producing of analysis-ready genotypes maximally harmonized across the different Lifebrain centres.

Novel longitudinal statistical tools, allowing to tackle challenges associated with multi-side mixed model lifespan data

Develop tools where goal is to identify models that optimally represent the consolidated findings of the consortium, and hence contribute to theory development and generalizability.

Dissemination tools and communication strategies - I

Tools include both printed material (flyers, flyer inlays, posters and factsheets etc.) as well as online / digital tools - website, social media accounts, newsletters and power point presentations. Project partners will be actively involved in determining appropriate tools, content generation and dissemination & communication opportunities associated with agreed DEC activities.

Kick-off meeting completed; advisory board, safety board, executive board instantiated

Organization of meeting and establishment of relevant boards

Dissemination tools and communication strategies II

Update strategy report conducted under D5.2

Data obtained from national registries; incl standardization, integration, quality control and pooling with existing data across sites

Coupling of existing data with national health, conscription and population registries. This will be done for the Nordic countries (Norway, Sweden, Denmark) as well as the Netherlands and Spain.

Policy reviews on cognitive & mental well-being across all age groups - I

Selected National/European policies will be reviewed and policy-makers engaged to determine the appropriateness and relevance of project results and how these results can lead to promotion of policies on ‘personalised health’ opportunities for European citizens
