In the present state of healthcare, usual medical care is generally given to the already diseased person, while the key link—personal health monitoring underlain by predictive, preventive, and personalised medicine (PPPM) techniques that are being intensively elaborated worldwide—is simply missing. It is this link, based on the recognition of subclinical conditions, prediction, and further preventive measures, that is capable of regulating morbidity and diminishing the rates of disability among able-bodied population, thus significantly cutting the traditionally high costs of treating the already diseased people. To achieve the above-mentioned goal—the elaboration of the PPPM concept and its practical implementation—it is necessary to create a fundamentally new strategy based upon the subclinical recognition of the signs—bioindicators of cryptic abnormalities long before the disease clinically manifests itself. The implementation of PPPM programme requires an adjusted technology for the proper interpretation of diagnostic data, which would allow for the current ‘physician-patient’ model to be gradually replaced by a novel model, ‘medical advisor-healthy men-at-risk’. This is the reason for an additional need in organising combinatorial scientific, clinical, training and educational projects in the area of PPPM to elicit the content of this new branch of medicine.

This narrative review examines the application of personalized nutrition (PN) through multi-OMICS and trans-OMICS in pediatric populations, particularly in relation to chronic conditions such as obesity, type 2 diabetes, and celiac disease. We synthesize evidence to identify biomarkers and gene–environment interactions and translate molecular insights into individualized dietary guidance. Even though PN represents a promising strategy for optimizing child health, significant challenges remain in translating molecular findings into practical, cost-effective, and equitable interventions. We advocate integrating this knowledge into clinical practice and developing policies and standardized methodologies that ensure accessibility for all pediatric populations.

The lecture presents up-to-date information on the prevalence of cancer in the world and in the Russian Federation. The main risk factors and causes of malignant tumors are considered. Particular attention is paid to the mechanisms of transformation of normal cells into tumor cells, and the role of oncogenes and anti-oncogenes in the initiation of malignant growth is shown. Based on modern information about carcinogenesis, the pathogenetic significance of the molecular mechanisms of malignant cell growth at various stages (initiation, promotion, progression) of the tumor process is shown. The mechanisms of evasion of tumors from the influence of immune and other mechanisms that restrain their emergence and development in the body are described, and it is also shown how the spread (metastasis) of malignant cells occurs. The modern tumor markers are presented, on the basis of which the earlier detection of malignant diseases is performed. Particular attention is paid to molecular diagnostic approaches to assessing the risk of occurrence and early diagnosis of malignant neoplasms. Genomic, epigenetic and interactomic tumor markers, which are used in leading domestic and foreign oncological centers, are considered. The most promising approaches to the creation of effective anticancer drugs obtained on the basis of the achievements of molecular biology and bioinformatics are highlighted.
