Accurate prediction of Adverse Drug Reactions (ADRs) at the patient level is essential for ensuring patient safety and optimizing healthcare outcomes. Traditional machine learning-based methods primarily focus on predicting potential ADRs for drugs, but they often fall short of capturing the complexity of individual demographics and the variations in ADRs experienced by different people. In this study, a novel framework called Precise Adverse Drug Reaction (PreciseADR) for patient-level ADR prediction is proposed.

Drug repurposing-identifying new therapeutic uses for approved drugs-is often a serendipitous and opportunistic endeavour to expand the use of drugs for new diseases. The clinical utility of drug-repurposing artificial intelligence (AI) models remains limited because these models focus narrowly on diseases for which some drugs already exist. Here we introduce TxGNN, a graph foundation model for zero-shot drug repurposing, identifying therapeutic candidates even for diseases with limited treatment options or no existing drugs.

Article Synopsis
  • Drug repurposing means using old, already approved medicines for new diseases.
  • The TXGNN model can help find new uses for drugs, even for diseases that have no treatments yet, and it's way better at predicting drug uses than other methods.
  • TXGNN not only predicts where drugs can be used but also explains its predictions clearly, making it easier for doctors to understand and investigate its suggestions.

Article Synopsis
  • Artificial intelligence is revolutionizing scientific discovery by enhancing research processes such as hypothesis generation, experiment design, and data interpretation.
  • Recent advances like self-supervised learning and geometric deep learning are improving model accuracy by utilizing vast amounts of unlabelled data and incorporating the structure of scientific data.
  • While generative AI is helping create innovations like drugs and proteins, challenges like data quality and the need for better understanding among AI developers and users persist, highlighting areas for further progress in AI research.

Developing personalized diagnostic strategies and targeted treatments requires a deep understanding of disease biology and the ability to dissect the relationship between molecular and genetic factors and their phenotypic consequences. However, such knowledge is fragmented across publications, non-standardized repositories, and evolving ontologies describing various scales of biological organization between genotypes and clinical phenotypes. Here, we present PrimeKG, a multimodal knowledge graph for precision medicine analyses.

Adverse drug reactions are the fourth leading cause of death in the US. Although women take longer to metabolize medications and experience twice the risk of developing adverse reactions compared with men, these sex differences are not comprehensively understood. Real-world clinical data provide an opportunity to estimate safety effects in otherwise understudied populations, i.
