Quantifying association and disparities between diabetes complications and COVID-19 outcomes: A retrospective study using electronic health records
PLOS ONE, 18(9).
TL;DR:
The presence of diabetes complications increases the risks of COVID-19 infection, hospitalization, and worse health outcomes with respect to in-hospital mortality and longer hospital length of stay, and health disparities in CO VID-19 outcomes across demographic groups in the diabetes population are shown.

Prediction of Sepsis Related Mortality: An Optimization Approach
IEEE JOURNAL OF BIOMEDICAL AND HEALTH INFORMATICS, 25(11), 4207–4216.
Contributors: *, N. Paramita n & O. Ozaltn
author keywords: Sepsis; SOFA score; optimization; mixed-integer programming; electronic health records
TL;DR:
This study proposes multiple strategies to adjust the SOFA score using mixed-integer programming to improve the in-hospital mortality prediction of septic patients based on Electronic Health Records (EHRs) to take advantage of optimization and data analysis while taking into account the medical expertise.
