Speaker: Casey Taylor, Johns Hopkins University

Title: Clinical decision support for unsolicited genomic results.


Poster: Taylor Poster 20230922

Abstract: Given that clinical genomic tests can be initiated outside of the clinical setting (for example, in a research study), from the clinician’s perspective, they can be characterized as “unsolicited,” which brings the challenge of how to determine the value and use of those data in patient care. Dr. Taylor will describe her ongoing research investigating the information and technical requirements for software to enable risk-benefit stratification of clinical decision support (CDS) for unsolicited genomic results (UGR) and the attributes needed for genomic service providers to decide how to prioritize and implement CDS based on UGR. Furthermore, Dr. Taylor is exploring how approaches used for UGR apply for prediction models. The broader impacts of this work are enhancing the productivity and effectiveness of genomic service providers; a greater awareness of how software can be used to support the work of genomic service providers; and an increased ability to implement CDS based upon UGR and prediction models within heterogeneous clinical IT infrastructures.

  • Title: Establishing the Causal Genetic Imaging Clinical Pathway for Brain-Related Disorders
  • NOTE – Alternate location: 1345 HSLC
  • Zoom:
  • Abstract: Our causal genetic imaging clinical (CGIC) pathway is motivated by the joint analysis of genetic, imaging, and clinical (GIC) data collected in many large-scale biomedical studies, such as the UK Biobank study and the Alzheimer’s Disease Neuroimaging Initiative (ADNI) study. We propose a statistical framework based on partially functional linear regression models and varying coefficient models to map CGIC pathway for phenotypes associated with brain-related disorders. We develop a joint model selection, estimation, and inference procedure by embedding imaging data in the reproducing kernel Hilbert space and imposing the penalty for the coefficients of scalar variables. We systematically investigate the theoretical properties of scalar and functional efficient estimators, including non-asymptotic error bound, minimax error bound, and asymptotic normality. We apply the proposed method to the ADNI and UKB datasets to identify important features from several millions of genetic polymorphisms and study the effects of a certain set of informative genetic variants and the hippocampus surface on different clinical variables.

Speaker: Joseph Ibrahim, University of North Carolina at Chapel Hill

Title: The Scale Transformed Power Prior for Time-to-Event Data

Poster: Ibrahim_Poster 20230915

Abstract: In clinical trials, data is often available from a previous trial with a different outcome (i.e., binary vs time-to-event). The power prior proposed by Ibrahim and Chen (2000) does not account for different data types in the context discussed here. To accommodate settings in which the historical data and the current data involve different data types, we develop the partial-borrowing scale transformed power prior (straPP) for several commonly used time-to-event models. The partial-borrowing straPP is developed through rescaling the parameter vector from the historical data to align with that of the new data using a transformation based on the Fisher information matrices from the two data models. We also develop the generalized scale transformed power prior (Gen-straPP) to provide added robustness for the case in which the scaled parameters are not equal. Several real data sets from the Eastern Cooperative Oncology Group are used to motivate the use of the proposed methods. We demonstrate the advantages of the partial-borrowing straPP over other common priors via simulation and real data analyses using the proportional hazards model and the mixture cure rate model.
