This article presents a data science review and our own evaluation on bio-element mediated aging of the human body from the point of view of homeodynamics of bioelementome. The study of bio-element basis of aging is currently one of the actively developing fields in gerontology. During postnatal ontogenesis, the bio-elementome shows no signs of stability. Being extremely dependent on endogenous and exogenous circumstances, the levels of macro- and microelements can either remain within the normal range or undergo significant changes, especially with the body aging. These bio-element developments appear to be very important in terms of a large number of currently known molecular, subcellular, cellular, and tissue mechanisms of aging (oxidative stress, loss of proteostasis, excessive telomere attrition, epigenetic landscape alterations, apoptosis, altered intercellular communication, and many others). Better understanding of metabolic pathways of essential bio-elements (intake in the gastrointestinal tract; absorption, including due to interaction with specific transporting proteins; spread through the circulatory system and the entire body; inclusion in specialized macromolecules and participation in their composition in biochemical processes; excretion from the body), as well as realizing their role in the mechanisms of senile tissue and organ involution, and features of age-related homeodynamics can significantly improve existing knowledge on the biology of aging.

Computerized cognitive training (CCT) is a rapidly developing area of cognitive rehabilitation at the intersection of information technology and healthcare, the constantly updated results of which can be successfully translated into practical application in clinical medicine and in particular in gerontology. The basis of CCT, as a non-invasive method of influencing the functional activity of the brain and the processes of neuroplasticity, is software for stimulating cognitive functions in order to improve their productivity. The level of scientific and practical interest in CCP technology is growing rapidly. The article reports on the current state of research on the use of CCT aimed at correcting cognitive impairment. The purpose of this work is to systematize the available scientific data in this area, as well as to promote further integration of research in the field of information technology into clinical practice, in particular, to study the potential of CCT as a promising therapeutic tool in the paradigm of successful aging and prevention of the progression of cognitive impairment. This noninvasive intervention may improve global cognitive function in patients with clinically defined impairments and during normal aging in cognitively healthy older adults. However, new studies with fully comparable protocols are needed to evaluate in more detail the duration of the effect and the effectiveness of CCT in preventing cognitive decline in the long term.

A study was conducted to investigate the associations of the diseases of the organ of vision and its accessory apparatus with anxiety and depression in the elderly people. The study included 678 participants of the ESSE-RF3 population study in the Arkhangelsk region in the age of 60-74 years. We used a questionnaire, including the hospital scale of anxiety and depression score (HADS), and the assessment of the ophthalmological status. It was found that all the study participants had diseases of the visual organ. Elevated depression scores were associated with sex, age, marital status (being single), and disability, elevated anxiety scores - with sex. The scores on the anxiety scale were on average 25% higher in participants whose visual acuity decreased to 0,5 units, and showed no independent associations with diagnosed ophthalmological diseases. The scores on the depression scale were on average 33% higher in participants with visual acuity 0,5 units, and 22% higher in the presence of retinopathy. In conclusion, anxiety and depression in the elderly people were more associated with visual deficits rather than with the presence of ophthalmological diseases underlying a decrease in functional status.

Multi-omics methods for analysing postgenomic data have become firmly established in the tools of molecular gerontology only in recent years, since previously there were no comprehensive integrative approaches adequate to the task of calculating biological age. This paper provides an overview of existing papers on multi-omics integrative approaches in calculating the biological age of a human. An analysis of the most common options for integrating methylomic, transcriptomic, proteomic, microbiomic and metabolomic datasets was carried out. We defined (1) concatenation (machine learning), in which models are developed using a concatenated data matrix, formed by combining multiple omics data sets; (2) fusion model approaches that create multiple intermediate submodels for different omics data to then build a final integrated model from the various intermediate submodels; and (3) transformation methods (via artificial intelligence) that first transform each of the single omics data sets into core plots or matrices, and then combine them all into one graph before building an integral complex model. It is unlikely that multi-omics approaches will find application in anti-aging personalized medicine, but they will undoubtedly deepen and expand the understanding of the fundamental processes standing behind the phenomenon of the biological aging clocks.

Alzheimer's disease (AD) is the most common neurodegenerative disorder, characterized by progressive cognitive decline. This review discusses current therapeutic strategies for the treatment of Alzheimer's disease, their limitations, and potential prospects. The feasibility of comprehensive approach for AD therapy is considered in contrast to the classical method in the development of therapeutic strategy. Leu-Ile, Glu-Trp, Lys-Glu, Gly-Pro, Glu-Asp-Arg, Lys-Glu-Asp, Met-Glu-His-Phe-Pro-Gly-Pro short peptides are described as multitarget agents with a wide range of activity.

From the age of 25-30, the likelihood of developing pathological processes associated with aging begins to increase. Age-associated diseases (AAD) are a heterogeneous group of pathologies that are more likely to develop as they age. Clinically, the early development of AAD is identical to premature aging with all the ensuing consequences. Timely targeted detection of AAD will slow down age-related processes. In order to study the peculiarities of age-related morbidity (by circulation), age-associated pathology, the study included 5 600 people with a newly diagnosed diagnosis who applied to the municipal polyclinic of St. Petersburg in 2017-2023. During the study, heterogeneity of the timing of the manifestation of AAD at the population level was found. In addition, the median age of patients was comparable to the value of the developed age-specific incidence index, which serves as a basis for continuing research in order to comprehensively assess the properties and limitations of the considered indicator.

Metabolic syndrome is a group of disorders that are closely related to both the risk of developing type 2 diabetes mellitus and cardiovascular diseases, and generally leading to the phenomenon of premature aging of the body. Excessive accumulation of adipose tissue contributes to the development of chronic immune inflammation and oxidative stress, which are both precursors to various disorders, such as insulin resistance, arterial hypertension and dyslipidemia, but also trigger inflammatory processes in patients. An increasing number of studies support the importance of chronic immune inflammation in the pathogenesis of metabolic syndrome, as pro-inflammatory markers such as TNF-α, IL-1β, IL-6, monocyte chemotactic protein-1 and growth of vascular endothelium. Among a wide range of cytokines, monocyte chemotactic protein-1 is considered one of the most important chemokines, which activates monocytes and other immune cells actively involved in inflammation. Another important point of chronic immune inflammation is its impact on the mental health of patients with metabolic syndrome. Increased levels of anxiety and depression are associated with levels of pro-inflammatory cytokines produced by adipose tissue, which ultimately has an adverse effect on the cognitive status of patients.

In the treatment of coronavirus infections, it is important not only to understand the course of the disease, but also to understand what is happening in the human body, especially in the circulatory system, that is, which disorders lead to deterioration and further complications. Hemostasis disorder in COVID-19 plays an important role in the etiology and clinical manifestations of the disease. The ability to identify factors and risk groups for the development of thrombotic complications, the ability to dynamically interpret peripheral blood parameters and coagulograms, knowledge of diagnostic criteria for possible hemostasis disorders (for example, DIC syndrome, sepsis-associated coagulopathy, antiphospholipids, hemophagocytosis and hypercoagulation syndrome) are necessary to determine the indications for the test. Differentiated prescribing of clinically justified therapy (including anticoagulants and blood components) is important, which determines the complexity of treatment and prognosis for patients with COVID-19. This article is a review of the literature on the topic of hemostasis disorders in elderly and senile patients with mesenteric thrombosis in COVID 19 over the past few years.

Assessing and monitoring social policies designed to enhance the well-being of older adults necessitates a comprehensive metric that encompasses all facets of their lives. In 2019, a cross-sectional study was carried out in Tehran, Iran, involving interviews with 1 280 older individuals to gauge their well-being. The Older Adults' Social Well-being Index (OSWI) was formulated following the composite indicator construction methodology advocated by the Organization for Economic Co-operation and Development. The study revealed that physical health, living standards, insurance coverage, subjective well-being, and social relationships collectively accounted for 54, 67% of the variation in social well-being. District 22 emerged as the most favorable locale in terms of OSWI, while District 18 lagged behind as the least suitable. The municipal districts of Tehran can be categorized into five distinct groups based on the well-being of their residents. By employing OSWI, the study succinctly encapsulates critical dimensions of older adults' lives, uncovering significant disparities in social well-being across Tehran's districts.

The review describes the involvement of various hyaluronic acid receptors, including CD44, RHAMM, HARE, TLR, LYVE-1, in maintaining normal homeostasis and aging, as well as in the development of age-associated inflammatory processes (inflamaging) and malignant tumors. The association of CD44 receptor activation with immune cells and the development of coronary heart disease has been shown. In addition, a link between the CD44 receptor and osteoarthritis has been shown, via TLR2 and TLR4. The oncogenic potential of RHAMM in relation to breast, prostate, leukemia, pancreas, lung and glioblastoma cancers has been described, with the strongest expression observed in metastatic tumors. In vivo and in vitro experiments, it was found that fragments of hyaluronic acid with a length of 4 to 25 disaccharides can contribute to the proliferation of lymphatic endothelial cells and lymphangiogenesis. Thus, hyaluronic acid receptors play an important role in the aging process through the regulation of inflamaging and in the development of malignant neoplasms.
