UPCOMING LECTURES AND SEMINARS

Please join us for a special summer Laboratory Medicine Grand Rounds (LMGR) on Wednesday, July 18, 2018 from 4-5 PM in HSB room T747:

The Importance of Reproducible Research in High-Throughput Biology: Case Studies in Forensic Bioinformatics

Keith Baggerly, PhD
Professor, Department of Bioinformatics and Computational Biology, Division of Quantitative Sciences
The University of Texas MD Anderson Cancer Center

Session description: Modern high-dimensional biological assays let us ask detailed questions about how diseases operate, but our intuition about what answers “should” look like in high dimensions is very poor. This lack of intuition means careful data processing is essential; without it we may have to apply “forensic bioinformatics” to work backwards from data and results to infer what the methods must have been. We describe case studies in which our reconstructions revealed analysis errors with the potential to impact patient care, and discuss implications for data sharing and ways to do things better.

After viewing this lecture, attendees should be able to:

  • List three common types of data analysis and processing errors
  • Relate examples of how these types of errors could negatively affect patient care
  • Discuss ways of reducing the problem and highlight outstanding challenges

This lecture can also be attended by live streaming via Zoom: https://www.zoom.us/j/414978331

Title: U-Net for Cerebral Cortical MR Image Segmentation

Abstract:

Cerebral cortex segmentation from three-dimensional structural Magnetic Resonance (MR) brain images plays an important role in measuring loss of cortical tissues for disorders such as Alzheimer’s disease (AD). U-Net, a type of deep convolutional neural networks architecture, is a widely-used approach for biomedical image segmentation in recent years.

In this thesis, I implemented 2D/3D U-Nets on MR images from 20 patients with labeled cerebral tissues and regions. A two-stage pipeline was designed for this task. In stage one, U-Net aims to generate a mask of grey matter to filter out other tissues in brain MRI images. In stage two, a similar U-Net architecture is used to label cerebral cortex sub-regions from images which only contains grey matter.

Both 2D U-Net and 3D U-Net do not work for labeling gyri/sulci, and only achieve approximate $55\%$ Dice overlap for labeling cortex regions. In contrast, the cerebral cortex segmentation package in FreeSurfer achieves over $90\%$ Dice overlap for labeling gyri/sulci by using a graphical-based probabilistic estimation method with prior information.

I believe that the main reason of bad performance of 2D/3D U-Net is the loss of global position information of pixels/voxels by cutting original MR images into small parts. The U-net architecture has weakness of handling high resolution 3D images with imbalanced number of classes. In the feature work, researchers could create hybrid methods to combine deep neural networks architectures with prior information to label cerebral cortical sub-regions.

Title: The Use of Inter-Provider Variation in Measuring Healthcare Performance

Abstract: To monitor and improve healthcare in the US, providers are required to report healthcare measures as part of regulatory and compensatory systems. However, there are growing concerns that the collection and reporting of these measures may be counter-productive to provider efforts to improve care. Variations in care are known to adversely affect quality, but studies on the relationship of variation within measures and performance of those measures are lacking. We aimed to test if inter-provider variation of a healthcare measure was associated with performance of that measure and thereby establish a model for identifying measures that might be more likely associated with opportunities to improve care. We found that between 14% and 23% of the performance of our chosen measure was associated with variation between providers. This finding suggests that inter-provider variance of a measure can be used to help identify measures where opportunities for improvement of clinical processes exist.

PUBLICATIONS AND PRESENTATIONS

Dr. Diane Korngiebel presented at a National Academies workshop in Washington, DC, “Improving Health for Small Populations,” Jan. 18-19, 2018. Dr. Korngiebel’s presentation, “Addressing the Challenges of Research with Small Populations,” focused on the ethical framing for research with populations whose numbers are small, how qualitative context—determined in collaboration with community partners—might inform quantitative “neighbor borrowing” for data aggregation, and concluded by describing the importance of co-production methods, in which users and other key stakeholders partner together, as the way forward for improving health research and powering healthcare innovation.

The final publication from the workshop, Improving Health Research on Small Populations, is now available. The electronic version can be viewed, read, and downloaded for free at:https://www.nap.edu/catalog/25112/improving-health-research-on-small-populations-proceedings-of-a-workshop.

 

Paper accepted to AMIA 2018:

A Closer Look at Health Information Seeking by Older Adults and Involved Family and Friends: Design Considerations for Health Information Technologies

Abstract

Older adults are the largest consumers of healthcare. As part of a broader study of personal health information management (PHIM), we interviewed older adults in King County, Washington, and their involved family and friends (FF), regarding health information (HI) sources they seek and utilize. Analysis of interview transcripts revealed four main themes: 1) older adults and FF consider healthcare providers the foundational source of HI; 2) older adults utilize FF for seeking, sharing, and interpreting HI, while FF serve as surrogate seekers and experience-based experts; 3) nline searching is common, but confidence in assessing the quality of online HI is often lacking; 4) a smorgasbord approach is frequently utilized by older adults and FF for gathering and clarifying HI. Design considerations include: facilitating access to quality provider-vetted HI, incorporating older adults and FF in the design process, and creating shared spaces for communication of HI among older adults, FF, and providers

 The NIH awarded a new 5-year center award: “The Center for Reproducible Biomedical Modeling”. The center is led by Herb Sauro (UW BioEngineering), and includes project leads John Gennari, Ion Moraru (U.Conn.) and Jonathan Karr (Mt. Sinai).

The goals of the project are to help scientists build comprehensive predictive models of biological systems. These biosimulation models should be understandable, reproducible, reusable, and composable. The center includes collaborative ties to biosimulation model repositories and curators at EBI and the U. of Auckland, as well as connections to relevant journal editors. The  BHI portion of the project will be to build ontologies and tools to semantically annotate biosimulation models, and to aid in making their construction more reproducible.  The project will be funded by the NIBIB and the NIGMS.
