Fisher's exact test is widely used in biomedical research, particularly in genomic profile analysis. Since in most databases, the frequency distribution of genes is right skewed, we show here that its use can lead to excessive false-positive discoveries. We propose to apply Zelen's exact test on a stratification of the gene set; this solves the false discovery problem, and should avoid misleading interpretations of lists of genes produced by various genome-wide analysis technologies.

Background: The implementation of large language models (LLMs), such as BART (Bidirectional and Auto-Regressive Transformers) and GPT-4, has revolutionized the extraction of insights from unstructured text. These advancements have expanded into health care, allowing analysis of social media for public health insights. However, the detection of drug discontinuation events (DDEs) remains underexplored.

Background: Current evidence suggests higher physical activity (PA) levels are associated with a reduced risk of colorectal cancer (CRC). However, the mediating role of the circulating metabolome in this relationship remains unclear.
Methods: Targeted metabolomics data from 6,055 participants in the EPIC cohort were used to identify metabolites associated with PA and derive a metabolomic signature of PA levels.

Plastic pollution, particularly microplastics (MPs), poses a significant global threat to ecosystems and human health, necessitating innovative remediation strategies. Biocompatible and biodegradable plastic-binding peptides (PBPs) offer a potential solution through targeted adsorption and subsequent MP detection or removal from the environment. A challenge in discovering plastic-binding peptides is the vast combinatorial space of possible peptides (, over 10 for 12-mer peptides), which far exceeds the sample sizes typically reachable by experiments or biophysics-based computational methods.

High intraocular pressure (IOP) is an important risk factor for glaucoma, which is influenced by genetic and environmental factors. However, the etiology of high IOP remains uncertain. Metabolites are compounds involved in metabolism which provide a link between the internal (genetic) and external environments.

Per- and polyfluoroalkyl substances (PFASs) are widely used in consumer products and are easily encountered in daily life. PFASs that accumulate in the human body can negatively affect adolescent health. This study aimed to identify key exposure pathways that influence serum PFAS levels in Korean adolescents, using data from the Korean National Environmental Health Survey (2018-2020) cycle 4.
