Meld 3.0 for Liver Allocation: Results From the Liver Simulated Allocation Model
*Purpose: Priority on the US liver transplant waitlist is determined by the model for end-stage liver disease (MELD), a score composed of serum bilirubin, creatinine,…2022 American Transplant Congress
Evaluating the Performance and External Validity of Machine Learning-Based Prediction Models in Liver Transplantation: An International Study
*Purpose: National liver transplant (LT) registries are curated in many countries. We compared data from three national registries and developed machine learning algorithm (MLA)-based models…2022 American Transplant Congress
Computer vs Human-Based Prediction and Stratification of the Risk of Long-Term Kidney Allograft Failure
1Paris Transplant Group, Paris, France, 2NYU Langone Health, New York, NY, 3UCLA, Los Angeles, CA
*Purpose: Clinical decision-making process after transplantation is mainly driven by patient individual risk of allograft failure prediction assessed by physicians. However, this task remains difficult…2022 American Transplant Congress
A Hybrid Model Combining Survival Analysis, Knapsack Optimization and Supervised Learning to Extrapolate the Evolution of Kidney Transplantation Patients from Donors with Expanded Criteria After Controlled Circulatory Death
*Purpose: Kidney transplantation (KT) with expanded criteria donors (ECD) after controlled circulatory death (cDCD) in high-risk patients is being debated. We categorize patients via a…2022 American Transplant Congress
Dynamic Risk Prediction of Kidney Graft Failure After Deceased Donor Transplant
*Purpose: Identifying kidney transplant recipients at risk of graft failure allows for early intervention in clinical care. We developed a dynamic risk prediction model based…2022 American Transplant Congress
Four Separate Frailty Metrics Lack Concordance and Are Non-Reflective of the Kidney Transplant Listing Outcome: A Large Single Center Review
Transplant Surgery, Emory University Hospital, Atlanta, GA
*Purpose: It is well known that functional status has prognostic value for post-surgical outcomes, however pre-transplant patients are not required to undergo objective frailty testing.…2022 American Transplant Congress
Development of a Radiomics-Based Model to Predict Graft Fibrosis in Liver Transplant Recipients: A Pilot Study
*Purpose: Recurrent fibrosis complicates 40% of Liver transplants (LT), compromising long-term survival. We evaluated the ability of a model combining radiomic features on CT scans…2022 American Transplant Congress
Factors Predicting Early Extubation After Liver Transplantation
1Transplant Institute, Tampa General Hospital, Tampa, FL, 2University of South Florida, Tampa, FL
*Purpose: Early extubation (either intraoperative or within 6 hours post operatively) is an important component of enhanced recovery pathways. The goal of the study was…2022 American Transplant Congress
Non-Invasive Metabolite-Based Urine Signature Detects Over-Immunosuppression in Renal Transplant Recipients
*Purpose: Managing complications related to over-immunosuppression represents a growing challenge in post-transplant care, with infections accounting for the second leading cause of death with functioning…2022 American Transplant Congress
Clinical Impact of a Modified Lung Allocation Score That Mitigates Selection Bias
*Purpose: The U.S. lung allocation system uses the Lung Allocation Score (LAS) to prioritize lung transplant candidates. Selection bias, induced by dependent censoring of waitlisted…
