Common data models standardize the structures and semantics of health datasets, enabling reproducibility large-scale studies that leverage from multiple locations settings. The Observational Medical Outcomes Partnership Data Model (OMOP CDM) is one leading common models. While there a strong incentive to convert datasets OMOP, conversion time resource-intensive, leaving research community in need tools for mapping OMOP. We propose an extract, transform, load (ETL) framework metadata-driven...

Machine learning (ML) has enabled healthcare discoveries by facilitating efficient modeling, such as for cancer screening. Unlike clinical trials, real-world data used in ML are often gathered multiple purposes, leading to bias and missing information a specific classification task. This challenge is especially pronounced because of stringent ethical considerations resource constraints.This study proposed an integrated approach enhance the quality health evidence from task predicting...

Abstract Vibrio cholerae, the bacterial pathogen responsible for diarrheal disease cholera, resides in aquatic environment between outbreaks. For bacteria, genetic variation by lateral gene transfer (LGT) is important survival and adaptation. In environment, V. cholerae predominantly found biofilms associated with chitinous organisms or chitin “rain”. Chitin induces competency which can lead to LGT. also subjected predation pressure protist. Here we investigated whether protozoal affected...
