HAC faculty engage in bi-directional healthcare, nursing science, and biomedical research activities on a broad range of applications. Methods and techniques developed by HAC investigators are tested and validated on specific pilot projects and then translated into clinical settings. HAC investigators provide consultation on innovative approaches (e.g., visualization, connectomics, data mining and classification, pattern excenttraction, motion-charts, computable phenotypes, predictive big data analytics). For interrogating complex studies involving information obtained from multiple-sources (e.g., unstructured clinical notes, imaging, genetics, cognitive assessments), HAC faculty provide resources to manage, model and interpret the data. Below are some examples of case-studies, involving big healthcare data, that HAC faculty have recently investigated and published in peer-reviewed journals.

Big Alzheimer’s Disease Data

ADNI Archive

www.adni-info.org

Types of Data

Clinical data: demographics, clinical assessments, cognitive assessments
Imaging data: sMRI, fMRI, DTI, PiB/FDG PET
Genetics data: Ilumina SNP genotyping
Chemical biomarker: lab tests, proteomics

Sample Size

Each data modality comes with a different number of cohorts. Generally, 200 ≤ N ≤ 2,500 .
For instance, we had previously conducted ADNI studies with N > 500 [PMIDs: 26918190, 26444770, 25940587]

Clinical Relevance

ADNI provides interesting data modalities, multiple cohorts (e.g., early-onset, mild, and severe dementia, controls) that allow effective model training and validation

NACC Archive

www.alz.washington.edu

Types of Data

Clinical data: treatments, diagnosis, clinical assessments, cognitive tests
Imaging data: sMRI, fMRI
Genetics data: SNP genotypes
Biospecimen: blood, buffy coat, brain tissue
Demographics: family history, phenotypes

Sample Size

This collection includes over 5,000 unique subjects with an average of 6 years of follow-up. Not all data elements/cases are complete

Clinical Relevance

NACC data facilitates the exploration of GWAS and diverse phenotypes. These data provide means to do exploratory neuropathological studies of dementia and cognitive decline, accounting for risk alleles like APOE ε4 and protective alleles APOE ε2

Questions

  • Identify the relation between observed clinical phenotypes and expected behavior
  • Prognosticate future cognitive decline (3-12 months prospectively) as a function of imaging data and clinical assessment (both model-based and model-free machine learning prediction methods will be used)
  • Derive and interpret the classifications of subjects into clusters using the harmonized and aggregated data from multiple sources

Big Autism Research Data

ABIDE

www.goo.gl/QC6poj

Types of Data

sMRI (N=476)
fMRI (N=1,159)
Meta-data (CSV)
Pheno (lots of missing data)
Dictionary: ABIDE_Disctionary_V1.02

Sample Size

ABIDE (Autism Brain Imaging Data Exchange) includes functional and structural brain imaging data collected at 23 international brain imaging laboratories
and N = 1,100 and k= 2,100

Clinical Relevance

Aims to accelerate the understanding of the neural bases of autism. ABIDE ultimate goal is to facilitate discovery science and comparisons across samples

Questions

  • Identify the specific neural processes discriminating between HCs and ASDs subjects by examining performance brain activation (fMRI) and brain anatomy (sMRI)
  • Examine disease (ASD) heterogeneity, e.g., symptoms, symptom severity, differences in IQ, total brain volume, surface area, GM cortical thickness, and psychiatric comorbidity
  • Examine the effects of demographic (e.g., age, gender) and phenotypic/clinical factors
  • Examine differences (HC vs. ASD) in various functional domains (visual, executive, language, social processing, cognition), DSM-Dx, hand, FIQ/VIQ/PIQ, ADI-R Social/Verbal/RRB/Onset, ADOS, SRS, SCQ, AQ, EyesStatus rs-fMRI
