Francesca Vitali, PhD

After completing her Bachelor's Degree and Master's Degree in Biomedical Engineering at the University of Pavia, Dr. Vitali received her PhD in Bioinformatics and Biomedical Engineering from the University of Pavia, Italy. Before joining the Lussier Research Group, she was a postdoctoral researcher at the Bioinformatics, Mathematical Modelling and Synthetic Biology (BMS) Lab at the University of Pavia under the mentorship of Prof. Riccardo Bellazzi. Her work mainly focused on developing computational methods to support drug repurposing and polypharmacology. During her career, Dr. Vitali developed strong programming experience with different languages and solid knowledge of data mining, statistics, graph theory, machine learning, and data integration techniques. One of the key aspects in these methods is their flexibility to make them suitable for use in different contexts. Her research was conducted in an expert multi¬disciplinary collaborative team, which included collaborations with international laboratories and pharmaceutical industries such as Sanofi and AstraZeneca.

Jungwei Fan, PhD

Jungwei received his Ph.D. in Biomedical Informatics from Columbia University. His dissertation was on reciprocal solutions to make biomedical terminology/ontology and natural language process (NLP) benefit each other. In one direction, he developed NLP methods that used context- and content-based features to audit semantic classification of the Unified Medical Language System (UMLS) concepts. In the other direction, he developed methods of using the UMLS semantic information to improve NLP tasks such as word sense disambiguation (WSD) and syntactic parsing. Two of the derived journal articles were selected as best papers in Yearbook of Medical Informatics by the International Medical Informatics Association. After completing Ph.D. in 2010, Jungwei joined Kaiser Permanente Southern California as an informatics scientist to work with real world data and requirements in healthcare industry. He spent six years with hands-on architecting and developing a full-fledged, scalable NLP pipeline based on the Unstructured Information Management Architecture (UIMA). The pipeline generated significant value through applications in computer-assisted medical coding and preventive medicine. In addition to operational duties, he continued research along several tracks: 1) applied NLP for preventive medicine of cardiovascular diseases, 2) investigated technical benefits and issues in cross-institution NLP collaboration, 3) developed syntactic annotation guidelines with emphasis on handling ungrammatical clinical sentences, and 4) used NLP and big data technology to identify health issues in massive consumer product reviews. In 2016, Jungwei joined the Center for Biomedical Informatics & Biostatistics at the University of Arizona to contribute his clinical informatics skills for precision medicine and health disparity research. His current endeavor is on innovating solutions that use electronic medical records and genomic data to facilitate clinical research. The active projects involve investigation into comorbidities and methods of case-based reasoning.

PRECISION HEALTH INITIATIVE

FACT SHEET: Obama Administration Announces Key Actions to Accelerate Precision Medicine Initiative

White House Announcement: UA Health Sciences Commits Biomedical Informatics and Genome Medicine Teams to National Precision Medicine Initiative

In response to the national Precision Medicine Initiative (PMI), UAHS has committed significant resources to expand the clinical utility of its open-source, patient-centric analytic methods, such as the N-of-1-pathways software, which aids physicians in interpreting the dynamic changes of disease-associated gene expression arising from patients’ own DNA blueprints. As part of the initiative, UAHS will translate large-scale clinical and genomic data into actionable individual outcomes through two of its centers: the UA Center for Biomedical Informatics and Biostatistics (CB2) and the UA Center for Applied Genetics and Genomic Medicine (TCAG2M). Both centers bring together physicians, scientists, patients and other key stakeholders to develop strategies that advance understanding of the factors contributing to individual health and disease and personalized approaches to disease prevention, early detection and treatment.

Yves Lussier, MD, FACMI, will lead the UAHS patient-centric analytical methods and was invited to attend the Precision Medicine Initiative Summit held Feb 25th in Washington, D.C. UAHS’ involvement in the PMI was initiated and facilitated by Ikbel Achour, PhD, who serves as CB2’s director for precision health. Dr. Lussier collaborates closely with Kenneth S. Ramos, MD, PhD, PharmB, associate vice president for precision health sciences, director of the UA TCAG2M and an elected member of the National Academy of Medicine.

ICD-9/ICD-10

ICD-9-CM To ICD-10-CM Conversion Tool

Vol.3 ICD-9-CM to ICD-10-PCS Conversion Tool

Impact. ICD-9 to ICD-10 transition based on:

  • All reimbursed payments for primary care patients of University of Illinois
  • 38,644 patients
  • 1,446,581 patient encounters
  • $382 million in payments

N-OF-1-PATHWAYS

N-of-1-Pathways Tool

In this era of precision medicine, accurate personal transcriptome interpretation and N-of-1 (single-subject) efficacy trials remain unmet challenges. We therefore developed a method, “N-of-1-pathways,” that translates gene expression data profiles into disease mechanism significance for a pair of samples - one patient at the time.

The emergence of precision medicine ushered in the opportunity to incorporate individual molecular data into patient care. In contrast to personal DNA sequencing profiling increasingly pursued in clinical practice, genome-wide transcriptome profiling has often provided biological information at the gene and pathway levels that are common and applicable only to a larger cohort. The N-of-1-pathways method, a global framework, relies on three principles: i) the statistical universe is a single patient/sample; ii) significance is derived from genesets/biomodules; and iii) similarity metric of inter-mechanisms’ relationships. N-of-1-pathways provides a unique and novel framework for N-of-1-studies (e.g. patients, cell-lines, tissues, etc.) aimed at predicting individual response to therapy and biomarker discovery. N-of-1-pathways offers opportunities to include patient-centered “omics” reports into electronic medical records for individualized clinical interpretation and precise treatment.

Integrative genomics analyses unveil downstream biological effectors of disease-specific polymorphisms buried in intergenic regions

Functionally altered biological mechanisms arising from disease-associated polymorphisms, remain difficult to characterise when those variants are intergenic, or, fall between genes. We sought to identify shared downstream mechanisms by which inter- and intragenic single-nucleotide polymorphisms (SNPs) contribute to a specific physiopathology. Using computational modelling of 2 million pairs of disease-associated SNPs drawn from genome-wide association studies (GWAS), integrated with expression Quantitative Trait Loci (eQTL) and Gene Ontology functional annotations, we predicted 3,870 inter–intra and inter–intra SNP pairs with convergent biological mechanisms (FDR 0.05). These prioritised SNP pairs with overlapping messenger RNA targets or similar functional annotations were more likely to be associated with the same disease than unrelated pathologies (OR412). We additionally confirmed synergistic and antagonistic genetic interactions for a subset of prioritised SNP pairs in independent studies of Alzheimer’s disease (entropy P = 0.046), bladder cancer (entropy P = 0.039), and rheumatoid arthritis (PheWAS case–control Po10− 4). Using ENCODE data sets, we further statistically validated that the biological mechanisms shared within prioritised SNP pairs are frequently governed by matching transcription factor binding sites and long-range chromatin interactions. These results provide a ‘roadmap’ of disease mechanisms emerging from GWAS and further identify candidate therapeutic targets among downstream effectors of intergenic SNPs.
