Transcript of GAAIN Newsletter Winter/Spring 2016
IN THIS ISSUE:
WELCOME From GAAIN’s PI, Arthur W. Toga
It is with great pleasure I introduce you to the inaugural issue of GAAINews, the newsletter for the Global Alzheimer’s Association Interactive
Network (GAAIN). Since its launch on September 15, 2013, GAAN has made tremendous strides to connect scientists worldwide with data and resources. This issue of GAAINews highlights the goals of the GAAIN project, an introduction of the GAAIN systems (the GAAIN Scoreboard and GAAIN Interrogator), GAAIN’s presence at the Alzheimer’s Association International Conference and the Data Integration in Life Sciences conference, the establishment of 30 active Data Partners and a note from our funders. I hope this issue shares our excitement and passion for connecting researchers around the global and accelerating big data research in the field of Alzheimer’s disease. As we continue our work, we look forward to establishing additional partnerships and creating novel approaches for big data science in dementia research. Lastly, I personally invite you to explore GAAIN by visiting www.gaain.org.
With Regards,

THE FIRST OF ITS KIND
The Global Alzheimer’s Association Interactive Network (GAAIN) has developed the first, usable online research platform to link scientists with the data and tools. Investigators can get answers to complex scientific questions about Alzheimer’s disease through facilitating and sharing Alzheimer’s disease research data by joining our global network of Alzheimer’s disease study centers that share data. Since the launch of GAAIN’s website (www.gaain.org) prior to September 15, 2013, the GAAIN team has recruited over one hundred data partners and affiliates to join the GAAIN effort to accelerate Alzheimer’s disease research. These groups provide resources and data that enable investigators to perform comparative data analysis and cohort discovery. GAAIN, funded by the Alzheimer’s Association, continues to improve and expand while reaching out to new potential Data Partners in order to develop a comprehensive and efficient platform where investigators can search and access Alzheimer’s disease data in a collaborative and innovative manner.
GAAIN AIMS TO CHANGE THE WAY INVESTIGATORS APPROACH ALZHEIMER’S DISEASE RESEARCH
GAAIN provides an unprecedented opportunity to the Alzheimer’s disease research community. By bringing investigators and data holders in a common, virtual space, scientific exchange and discovery can be rapid, conclusive and groundbreaking – unlike ever before across all complex diseases. GAAIN provides a unique solution for Data Partners by addressing specific access control issues related to data sharing in a way never done before. GAAIN leaves the control over data access in the hands of the data owner and provided mecha-nisms for sharing data that have a low cost for the data owner. In addition, GAAIN gives data owners credit by presenting the Partner’s logo and a link to website on all GAAIN interfaces. Furthermore, the GAAIN system maximizes usability of data by transforming individual source data into a common schema and encoding standard thereby
making direct comparisons possible without requiring investigators to first decode data from each data source. For investigators, the GAAIN system invites exploration by presenting an interactive graphical interface through which data may be quickly and easily understood. It also strengthens the validation of research results by maximizing cohort sample size and extending the opportunity for an independent cohort to replicate research findings.
GAAIN RECEIVES PRAISE AND POSITIVE FEEDBACK AT AAIC 2015
With thousands of attendees, the 2015 Alz-heimer’s Asso-
ciation International Conference in Washington D.C. presented itself as a fantastic opportunity to engage with Alzheimer’s disease researchers and demonstrate the GAAIN systems at the GAAIN booth in the exhibit hall. Overall, researchers expressed their excitement for the opportunity to interact and immediately receive responses to their scientific ques-tions. One researcher remarked, “I can directly see the power and impact these tools [the GAAIN systems] can have on Alzheimer’s disease research. I look forward to working
with them in the future.” Many researchers and clinicians conveyed their interest and are currently in various stages of becoming a GAAIN data partner. The GAAIN team also presented at the Worldwide Alzhei-mer’s Disease Neuroimaging Initia-tive (WW-ADNI) meeting, the Data Sharing Platform in Alzheimer’s focused topic session, the Collab-oration of Alzheimer’s Prevention meeting. GAAIN also hosted a Meet and Greet for our partners designed to develop cross-relationships among our partners and to provide insight of GAAIN’s next steps. Please visit us at AAIC 2016 at our booth in the Exhibition Hall.
GAAIN UPHOLDS DATA SECURITY STANDARDS – THE DATA LIVES WITH OUR PARTNERS
GAAIN aims to build a comfortable online research community for investiga-
tors and data partners. We created interfaces that are easy to use and do not infringe upon data ownership and security set forth by our partners. Firstly, GAAIN never copies Partner data to its server disks, leaving our Partners in full control of their data contributions to GAAIN. We believe

GAAIN is in the process of onboarding 160+ data partners from around the globe.

GAAIN LAUNCHES TWO INTERACTIVE RESEARCH INTERFACES
GAAIN investigators can see what kinds of data are available to them by interacting with the GAAIN Scoreboard. Using its sleek and animated interface, the GAAIN Scoreboard provides researchers an instantaneous count of the number of subjects each Data Partner has data for in the GAAIN system based the investigator’s search criteria. Investigators simply select different data attributes and are provided results to their request instantly, both graphically and numerically. Investigators may also apply directly to each Data Partner for the full set of their data from this interface. GAAIN investigators can search all the data made available by the Data Partners using the GAAIN Interro-gator. The Interrogator shows in-vestigators how data fits together by graphing the data in interconnected views. Instead of typing numbers into text boxes, investigators search the data by interacting with graphs. The data is “interrogated” by manipu-lating the graphs, which changes the search parameters and automatically update the entire display. Searching takes place by dynamically defining cohorts and visually exploring the differences between them. Every search result shows the number of subjects from each Data Partner and directs investigators where to obtain the data from each Data Partner.
DATA SECURITY STANDARDS
there is no safer solution than keeping the data where it originates. Secondly, the contributed data is always managed securely using in-dustry-standard transmission pro-tocols. Thirdly, investigator access is solely managed and determined by our Data Partners. It is up to the partners to decide who may use their data.

A NOTE FROM OUR FUNDERS:
THE ALZHEIMER’S ASSOCIATION
Advancing our understanding of Alzheimer’s disease requires big data that is cataloged, aggregated and accessible. By linking scien-tists, projects and data together, the Global Alzheimer’s Association Interactive Network (GAAIN™) is leading the way to a new level of collaboration that is critical to find-ing solutions for this disease. The Alzheimer’s Association is commit-ted to providing essential resources like GAAIN to engage global ex-pertise and solve this worldwide epidemic. With the significant participation of the research com-munity, GAAIN is transforming the field, improving the way we exchange and interrogate data, and leading us closer to understating and stopping this disease.
