The article presents a comparative analysis of the process of population aging in the context of demographic and professional risks of depopulation among working population in Russia. The values of the main medical and demographic indicators of population aging for Russia and developed countries were given. The results of UN forecasts, probabilistic forecasts of the total number and some characteristics of the age-sex structure for the population of the Russian Federation were analyzed. The state of demographic disadvantage in Russia and in the world was convincingly shown. Particular attention was paid to the consideration of the demographic risks of a reduction in the working-age population and an increase in the burden on the working-age population. The need for further research on the use of geroprotectors and modern gerontotechnologies as means and methods for preventing premature decline in work ability, slowing down the aging process of workers, reducing the mortality rate among working population and increasing professional longevity has been proven.

The paper continues the study of the population ageing in the regions of the Northwestern Federal District. It characterized population ageing based on prospective ageing indicators that take into account remaining life expectancy. The dynamics of life expectancy (LE) at birth was analyzed. A computation and comparative analysis of the old age threshold for the regions that are part of the Northwestern Federal District have been carried out. A comparative analysis of ageing indicators - traditional and prospective (the proportion of the elderly and the share of the population above the old age threshold) was carried out. It has been found that there are no fundamental differences in the dynamics of life expectancy in older ages, as well as in the of old age threshold, between the regions considered. It is shown that for the male population in almost all regions in 2021, the value of the old age threshold is below 60 years, while for the female population the opposite inequality is observed. Thus, in 2021, the share of men over the old age threshold exceeds the proportion of the elderly in almost all regions considered, and for the female population, the share of the elderly is expected to be higher than the values of the prospective indicator.

After cholecystectomy, elderly patients require special attention, due to the influence of involution processes in the body on the formation of complications. To identify prognostic criteria for the formation of fatty liver degeneration in the long-term period of minimally invasive cholecystectomy, 159 men were examined. Dysregulation of the biliary tract was determined using magnetic resonance cholangiopancreatography, elastography and magnetic resonance imaging of the liver. Microbial markers of the wall microbiome of the intestine were determined using chromatography-mass spectrometry. The relationship between an increase in body mass index and a decrease in the amount of obligate microbiome (r=-0,43, p<0,050), as well as with the formation of fatty liver degeneration in elderly patients, was revealed. The features of vegetative regulation in elderly people with fatty liver degeneration have been determined. It has been proven that in old age, a decrease in the number of obligate anaerobic association of microorganisms of the small intestine (on average from 15 659 to 7 630 in persons of the 2nd age subgroup and from 1 457 to 17 837 in the 3rd) is a predictor of fatty liver degeneration. The prognostic algorithm developed on the basis of the analysis of highly informative signs makes it possible to identify with an accuracy of at least 75% a high risk of fatty liver degeneration in the long-term period of cholecystectomy.

Almost 90% of patients with type 2 diabetes mellitus (DM2) are obese. Obesity increases the risk of developing DM2 several times. The calculation of anthropometric indices is used to diagnose the severity of obesity, as well as to assess the risk associated with obesity. The aim of the study is to study the relationship between Body Mass Index (BMI), waist circumference to hip circumference ratio (waist-to-hip ratio, WC/HR), Body Roundness Index (BRI) and Visceral Adiposity Index (VAI) with the risk of hypoglycemia in elderly and senile patients with DM2. The study included 122 elderly and senile patients (mean age 71±6,18 years) with DM2. The study participants were divided into 2 groups: patients with cases of hypoglycemia (n=65) and patients without a history of hypoglycemia (n=57). We have found that lower BMI, WC/HR, BRI, and VAI values are significantly associated with an increased risk of hypoglycemia in patients with DM2 of older age groups.

Visual impairment due to ophthalmological diseases significantly affects functional activity in everyday life, since good eyesight is crucial in daily activities. Data from 837 respondents were studied, allowing for analysis of such medical and demographic indicators as age, gender, level of education, visual acuity arterial hypertension and diabetes mellitus. To measure functional status, the main activities in daily life (ADL) and instrumental activities in daily life (IADL) were evaluated using a modified version of the Katz scale and the IADL OARS scale. Statistical methods of Mantel-Hansel Chi-squared analysis were used to assess differences in the prevalence of functional blindness and visual deficit. The study showed that medical and demographic factors have a relatively smaller impact on vision deficiency compared to functional blindness, with age being a significant factor in both cases. Among the medical and demographic factors, the age of patients, as well as diabetes mellitus, significantly increase the development of visual deficiency and functional blindness. Functional blindness, in comparison with visual deficiency, causes more significant restrictions on activities in everyday life and instrumental activities in everyday life, and also causes dependence on help from others.

Understanding the recovery process of functional abilities post-COVID-19 in older inpatients with arterial hypertension and ischemic heart disease is important for optimising healthcare delivery and resources. Participants in this study were individuals undergoing hospital-based rehabilitation following COVID-19 (average age 66, n=183). They were categorised into groups with arterial hypertension (n=92), ischemic heart disease (n=18), both conditions (n=38), and a control group without these diseases (n=35). Functional abilities were assessed via the distance walked until signs of exhaustion (meters), handgrip strength (kilograms), and breath-holding time (seconds). Multiple regression analysis revealed that inpatients with arterial hypertension walked shorter distances (β=-19,183; p=0,050) but showed higher handgrip strength (β=3,735; p=0,025) compared to the control group. Post-rehabilitation, inpatients with hypertension demonstrated greater performance (β=40,435, p=0,024) and better improvement rates (β=47,337; p=0,016) in walked distance than those in the control group. Significant interaction effects between groups and pre-/post-rehabilitation changes were observed only for walking distance (β=34,74; p=0,02), with no significant interactions found for other measures. The findings indicate that older inpatients with arterial hypertension may experience comparable or enhanced recovery of functional abilities post-COVID-19. The presence of ischemic heart disease, alone or combined with hypertension, does not significantly impair rehabilitation outcomes compared to those without such conditions.

This review presents data from the literature on the characteristics of the course of chronic kidney disease from the perspective of the geriatric patient. Chronic kidney disease and progression of renal failure is a prototype model of premature and accelerated aging. Many authors have stated that a better mechanistic understanding of the phenomenon of premature aging, early diagnosis of chronic kidney disease, and a geriatric approach to the patient can improve the effectiveness of management and prolongation of life in this category of patients. Comprehensive geriatric assessment is one of the most important tools used by geriatricians and their teams to globally assess elderly patients and plan effective interventions. It is concluded that the use of comprehensive geriatric assessment in patients with chronic kidney disease may improve the clinical status of patients and allow selection of patients who may benefit most from renal replacement therapy compared to a conservative approach. And even in the early stages of chronic kidney disease, a comprehensive geriatric assessment may be useful in formulating a complete intervention plan and optimizing quality of life, autonomy, and prognosis. However, despite recognition of the importance of comprehensive geriatric assessment, the means to implement this tool in nephrology departments have not been developed and require special training programs and appropriate skills. It is concluded that much more needs to be done to realize the continuity of nephrologists and geriatricians in the provision of meaningful skilled care to older patients with chronic kidney disease.

In recent years, complications of drug therapy are an important medical problem. Data on adverse drug reactions (ADR) in patients of older age groups were analyzed. The object of the study was notification cards for unwanted reactions received from medical organizations of the Irkutsk region for period 2009-2020 years. The Narangio scale was used to assess the causality between ADR and medicines. Of the 1021 ADR notifications in patients over 65 years of age, 2/3 (668) are presented with ADR notifications in women, 353 (34,6%) in men. The presence of background diseases was registered in 915 notifications (89,6%). There were no gender differences except for a higher incidence of chronic obstructive pulmonary disease in men (7,2 and 3,5% respectively, p<0,05) and diabetes mellitus in women (14 and 3,5% respectively, p<0,05). ADRs for antibacterial agents amounted to 31,8%, drugs for the treatment of cardiovascular diseases - 10,5%, cases of therapeutic inefficiency - 5,1%. The ADR data statement was in line with the recommended form of 76%. The most common filling defect was incomplete patient information. The validity of the Narango causation was high. The deadlines for reporting data were observed in 89,1%. For effective interaction in the pharmacovigilance system, it is necessary in each medical organization to constantly inform about the procedure for pharmacovigilance, types of ADRs, the rules for their detection and the timing of data reporting. The work should be supervised by a trained specialist.

A review of the use of comprehensive geriatric assessment and its components in oncology is introduced. The evidence base for the increasing incidence of cancer in the elderly worldwide also presented. The management of older adults with cancer is challenging. Comprehensive Geriatric Assessment (CGA) has been shown by many authors to be a strong predictor of adverse events in geriatric oncology patients. CGA is recommended in oncology practice for many reasons: to identify health problems not usually detected in routine oncologic screening, to perform non-oncologic interventions, and to modify the cancer treatment plan. Comprehensive geriatric assessment is the gold standard in geriatric oncology for identifying patients at high risk for adverse outcomes and optimizing cancer treatment and overall management. Nevertheless, it can be stated that the final point in the search for evidence-based and effective frailty assessment tools in the practice of geriatric oncology has not yet been reached. It is concluded that the development of new scales and index scores, as well as the application of the CGA model in general, can provide adequate care for elderly cancer patients.

The foundation of healthy aging is the prevention of disability. In modern medical usage, a syndrome refers to a collection of symptoms and signs with a single underlying cause that may not yet be known. Geriatric syndromes, on the other hand, refer to multifactorial health conditions and occur when the accumulated effects of impairments in multiple systems make an older person vulnerable to situational changes. The use of the term "syndrome" in geriatrics emphasizes the multiple causes of a single manifestation involving an abundance of factors involving multiple organs and systems and is characterized by unique features of common health problems in older adults. It is the geriatric syndromes that can have a significant impact on quality of life and disability. Therefore, early detection of these medical conditions using targeted geriatric assessment is essential in geriatrics. Understanding the essence and feminology of geriatric syndromes, their correct positioning and interpretation is an extremely urgent problem. The main purpose of the presented review is precisely to try to answer these questions. In addition, it has not yet been determined whether geriatric syndromes should be included in the diagnosis (the only exception is sarcopenia syndrome, which was officially included in the 10th International Classification of Diseases in 2016).
