Practical considerations for integrating proteomics and metabolomics in pediatric multi-omics research are discussed, including popular code- and web-based tools, and recent examples of multi-omics studies in pediatric cohorts, concluding with current challenges and future outlooks for integrative multi-omics studies.
Abstract
Personalized medicine is essential for delivering efficacious care to children, yet pediatric-specific research and treatment guidelines lag behind those for adults. Multi-omics integration may offer clinicians biologically grounded patient stratification beyond traditional clinical biomarkers. While this approach holds promise for advancing precision medicine, it remains incompletely validated, and significant barriers to routine clinical implementation persist. In this review, we discuss practical considerations for integrating proteomics and metabolomics in pediatric multi-omics research. We describe popular code- and web-based tools, and recent examples of multi-omics studies in pediatric cohorts, concluding with current challenges and future outlooks for integrative multi-omics studies.
The value of MODPM lies not in stacking additional data layers but in building a multiscale, continuously learnable framework to link biological heterogeneity to clinically interpretable and actionable decisions.
Metabolomics has become a mainstream approach that examines the metabolic composition of biological systems in relation to their physiological and disease states. Using analytical techniques such as nuclear magnetic resonance spectroscopy and mass spectrometry, metabolomics enables detailed profiling of small molecules...

Multi-omics studies provide opportunities to investigate complex biological systems, but their interpretation can be complicated by numerous sources of variation. Here, we discuss the biological, analytical, and computational factors that can affect the reproducibility of omics studies. We introduce practical recommend...
Schizophrenia is widely recognized as a multifactorial disorder involving interactions among the central nervous system, immune system, metabolism, and gut microbiome. Mardon et al. highlighted the potential importance of the gut-brain axis in schizophrenia. Building on this perspective, this commentary examines the ne...

Neuropsychiatric and neurodegenerative disorders show wide variability in treatment response, thus limiting the effectiveness of traditional symptom-based neuropharmacology. Precision medicine offers a more targeted approach by combining pharmacogenomics, multi-omics data, and artificial intelligence to guide individua...
