The Dementias Platform UK (DPUK) Data Portal

Area of Science:

• Neuroscience
• Data Science
• Bioinformatics

Background:

• The Dementias Platform UK (DPUK) Data Portal addresses the need for centralized, secure data access in dementia research.
• Managing large-scale, multi-cohort data for complex analyses presents significant logistical and technical challenges.

Purpose of the Study:

• To describe the architecture and functionality of the Dementias Platform UK Data Portal.
• To highlight its role in facilitating secure and efficient data access for dementia research.

Main Methods:

• The Data Portal utilizes UK Secure eResearch Platform infrastructure with a 7-layered architecture for data management.
• It provides secure, auditable, remote access environments (VMware 'labs' with two-factor authentication) for data analysis.
• Automated, standardized procedures streamline data ingestion, curation, discovery, access brokerage, and analysis.

Main Results:

• The portal provides access to data for 3,370,929 individuals across 42 cohorts.
• In the last two years, 160 project proposals and 579 data access requests were received from 268 applicants across 72 institutions in 16 countries.
• Projects encompass varied analyses including multi-modal, machine learning, and Mendelian randomization.

Conclusions:

• The Dementias Platform UK Data Portal successfully facilitates collaborative dementia research by providing a robust and secure data management solution.
• Its streamlined processes reduce administrative burden and enhance the efficiency of accessing and analyzing large-scale cohort data.
• The platform supports diverse research methodologies, accelerating discoveries in the field of dementia.
