Study Notes

Renal Replacement Therapy (RRT) Prediction

The study aims to predict the outcome of RRT at the time of diagnosis using clinical data.
The dataset consists of 451 patients with 1202 data points from the Department of Laboratory Medicine, Konkuk University Medical Center.
The study uses logistic regression to analyze the data and predict RRT probabilities.
The top 10 algorithms were used to predict RRT 12 months ahead, with the results showing AUC values above 0.7.
The best ROC curves were obtained by testing various configurations, including feature extraction, data balancing, and dimensionality reduction.

Covid-19 Prediction

The study aims to predict the risk of severe disease from Covid-19 infection using remotely collected data.
The retrospective study included 556 patients with confirmed Covid-19, analyzing patient demographics, symptoms, and past medical history.
Multivariable logistic regression analysis was used to identify predictors of severe disease.
The model demonstrated good discriminative ability, with potential for remote triage and prioritization of patients.

Mucormycosis Prediction

Mucormycosis is a life-threatening fungal infection with increasing cases in India, particularly in Covid-19 patients.
The study aims to develop AI-based models to predict the risk of mucormycosis among Covid-19 patients at the time of hospital discharge.
The goal is to improve treatment success by facilitating early diagnosis and prevention of relapse.
