Serious adverse drug reactions are an important cause of hospitalization and can result in the withdrawal of licensed drugs. Genetic variation has been shown to influence adverse drug reaction susceptibility, and predictive genetic tests have been developed for a limited number of adverse drug reactions. The identification of patients with adverse drug reactions, obtaining samples for genetic analysis and rigorous evaluation of clinical test effectiveness represent significant challenges to predictive genetic test development. Using the example of serious drug-induced liver injury, we illustrate how a database of routinely collected electronic health records (EHRs) could be used to overcome these barriers by facilitating rapid recruitment to genome-wide association studies and supporting efficient randomized controlled trials of predictive genetic test effectiveness.

Highly multiplexed imaging reveals prognostic immune and stromal spatial biomarkers in breast cancer.

Spatial profiling of tissues promises to elucidate tumor-microenvironment interactions and generate prognostic and predictive biomarkers. We analyzed single-cell, spatial data from three multiplex imaging technologies: cyclic immunofluorescence (CycIF) data we generated from 102 breast cancer patients with clinical follow-up, and publicly available imaging mass cytometry and multiplex ion-beam imaging datasets. Similar single-cell phenotyping results across imaging platforms enabled combined analysis of epithelial phenotypes to delineate prognostic subtypes among estrogen-receptor positive (ER+) patients.

Baicalein, one of the major active flavonoids found in Scutellaria baicalensis, has been revealed to exhibit potent anti-inflammatory properties in allergic airway inflammation. This study aimed to explore the role of baicalein and its relevant mechanism in the treatment of allergic rhinitis (AR). The bioinformatics tools were used to predict the targets of baicalein and AR-related genes.

Objectives: This study aimed to identify factors predicting postoperative ICU admission, the need for orotracheal intubation (OTI), and the occurrence of supraglottic stenosis in children undergoing supraglottoplasty for laryngomalacia.
Methods: A retrospective analysis was conducted on 31 children (Dear Reviewer, we would have greatly preferred to include a larger sample size. However, as you know, this type of management is rare, and we deliberately selected a 7-year period to ensure a minimum of 30 children while avoiding significant differences in management guidelines over time.

Leukemia covers a broad category of cancer malignancies that specifically affect bone marrow and blood cells. While different kinds of leukemia have been identified, effective treatments are still lacking for most forms, and even those treatments considered effective can lead to relapses. MicroRNAs, or miRNAs, are short endogenous non-coding single-stranded RNAs that help control the epigenetics of gene expression.

Pancreatic ductal adenocarcinoma (PDAC) is projected to be the second leading cause of cancer-related death by 2030. Early identification is rare, with a 5-year overall survival (OS) of less than 10%. Advances in the understanding of PDAC tumor biology are needed to improve these outcomes.
