The aim of the study was features of ultrastructural changes in cellular elements and connective tissue carcass of the great saphenous vein (GSV) at varicose disease in depending on the duration of the disease in persons of different ages. An examination by light microscopy of 133 fragments of BPV, excised during phlebectomy in 19 patients, and an electron microscopic examination of 532 preparations were performed. Depending on the age of the patients, four age groups was distinguished: 18-44 years old (young people); 45-59 years (middle-aged people); 60-74 years old (the elderly), 75-90 years old (persons of senile age). In the wall of the GSV of young people with a small duration of the disease, there were poorly expressed pathomorphological changes characterized by moderately expressed endothelial dysfunction and minor hypertrophy of smooth muscle cells (SMC) of the middle shell. In the group of middle-aged people, in addition to age-related changes in the structure of the wall of varicose dilated GSV, pathological changes are noted that are characteristic of the long course of the disease with the development of endothelial dysfunction. The phenotypic heterogeneity of the SMC in the middle shell intensifies, and the communication links between them is altered. Disorganization of connective tissue leads to a decrease in the strength of the connective tissue vein skeleton. Hypertrophy of SMC, as a universal compensatory-adaptive response of cells, develops in response to an increase in functional load with hemodynamic disturbances in the veins of the lower limbs and to compensate for the quantitative deficiency of SMC as a result of their death. In elderly and senile age the duration of varicose disease is more than 10 years, on average - up to 25-30 years. The number of destructively altered SMC is increasing, degenerative processes and sclerotic changes are progressing. The ultrastructural analysis of biopsies showed that at the initial stage of development of varicose disease in young people with a small duration of varicose disease, morphological changes in the structure of the GSV wall are poorly expressed. With the increase in the age of the patient and the duration of the disease, changes in GSV are progressed. Involute degenerative-dystrophic changes are most pronounced in patients over 60 years of age and are an aggravating factor during varicose transformation of the GSV wall. In elderly and senile age, the compensatory possibilities of the cells decrease, the sclerotic degenerative changes in the wall of the GSV are progressed.

Background: Multimorbidity not only affects the quality of patients’ lives, but can also bring a heavy economic burden to individuals, families and society. The purpose of this study was to reveal the connections between diseases, especially the important role each disease played in the entire multimorbidity network. Methods: A total of 1,155,734 inpatients were enrolled through multistage stratified random sampling in Jilin Province in 2017. Categorical variables were compared using the Rao–Scott-χ2 test. Weighted networks were adopted to present the complex relationships of multimorbidity. Results: The distributions of the number of diseases differed significantly by gender, age and health insurance scheme (P < 0.001). Diseases of the respiratory system had the highest weight in multimorbidity in young people. Endocrine, nutritional and metabolic diseases and circulatory system diseases were often associated with other systemic diseases in middle aged and old people. Conclusions: Multimorbidity with respiratory system diseases in young people should not be overlooked. Additionally, effective prevention efforts that target endocrine, nutritional and metabolic diseases and circulatory system diseases are needed in middle aged and old people.

The article presents the results of a study of the dynamics of recurrent disability due to malignant neoplasms (ZNO) of the adult population in the Chechen Republic for the period 2008-2017. in comparison with the figures for the Russian Federation. In the Russian Federation, the dynamics of re-disability of the adult population due to the ZNO in the period 2008-2017 was characterized by an increase in the number of repeatedly recognized disabled (PPI), the level of which increased from 19.9 to 27.0 per 10 thousand people. Compared to 2008 (taken as 100%), the indicator of visibility of PPI was 135%. In the PPI contingent, the elderly prevailed with a negative trend of growth in their numbers. The proportion of young and middle-aged PPI decreased. In the Chechen Republic, the epidemiological picture of the disability of the adult population due to the ZNO was characterized by different dynamics. The number of PPI due to ZNO in the country decreased. Compared to 2008 (taken as 100%), the visibility index of the PPI was 57.0%; In the structure of recurrent disability due to ZNO, middle-aged and old-aged PPI prevailed, however, their proportion declined. There is a negative growth trend in the proportion of young people.

Abstract As smartphones came into wide use recently, it has become increasingly popular not only among young people, but among middle-aged people as well. Most smartphones adopt capacitive full touch screen, so touch commands are made by fingers unlike the PDAs in the past that use touch pens. In this case, a significant portion of the smartphone's screen is blocked by the finger so it is impossible to see the screens around the finger touching the screen; this causes difficulties in making precise inputs. To solve this problem, this research proposes a method of using simple AR markers to improve the interface of smartphones. A marker is placed in front of the smartphone camera. Then, the camera image of the marker is analyzed to determine the position of the marker as the position of the mouse cursor. This method can enable click, double-click, drag-and-drop used in PCs as well as touch, slide, long-touch-input in smartphones. Through this research, smartphone inputs can be made more precise and simple, and show the possibility of the application of a new concept of smartphone interface.

We measured the personalities, values, and preferences of more than 19,000 people who ranged in age from 18 to 68 and asked them to report how much they had changed in the past decade and/or to predict how much they would change in the next decade. Young people, middle-aged people, and older people all believed they had changed a lot in the past but would change relatively little in the future. People, it seems, regard the present as a watershed moment at which they have finally become the person they will be for the rest of their lives. This “end of history illusion” had practical consequences, leading people to overpay for future opportunities to indulge their current preferences.

Introduction. The process of involving children, adolescents and youth in the constantly developing information space is an objective reality. At the same time, the lack of monitored indices of the safety of electronic devices (ED) for the health of children and adolescents, the lack of a clearly built system of preventive measures require its development and improvement, which will reduce the risk of the digital information environment impact on the health of the younger generation. Materials and methods. The survey using a questionnaire, developed by specialists from the Research Institute of Hygiene and Health Protection of Children and Adolescents in 2017-2020, was used to collect data on the nature of ED using by schoolchildren and students in educational and leisure activities (1218 questionnaires). In 2017-2020, 805 schoolchildren and students from the Moscow gymnasium №12 and the Pirogov Russian National Research Medical University underwent an ophthalmological examination. Results. All the surveyed schoolchildren and students used ED. Analysis of the questionnaire data allowed us to determine the duration of continuous use of ED (computer, laptop, tablet, smartphone, etc.) by children, adolescents, and young people during school and vacation time. All categories of respondents both during the academic period and during holidays showed a high duration of continuous use of ED. Thus, the presence of a behavioral risk factor for the uncontrolled use of ED (long duration of continuous work with ED) was shown among all categories of respondents, which may cause the development of eye diseases. The analysis of the results obtained revealed significant negative values of the correlation coefficients between students’ visual acuity and the duration of their continuous use of both stationary (computer) and mobile (smartphone, tablet) ED. Discussion. The introduction of these preventive measures into the daily routine and lifestyle of children, adolescents, and young people will help prevent visual acuity disorders. Conclusion. It is necessary to introduce hygienic rationing of the frequency and duration of the possible influence of ED not only during the educational process but also in leisure time to increase the awareness of parents and the degree of their control over the use of ED. To elevate awareness of all ED users’ categories it is necessary to intensify work to promote the rules for the safe use of ED and related foundations of a healthy lifestyle and self-control over ED use. In connection with the development of the digital educational environment, it is advisable to improve the hygienic standardization of text information in electronic publications for children, adolescents, and students. To prevent the symptoms of eye fatigue, it is advisable to limit continuous work with a bright screen (no more than 60 minutes), followed by a break of at least 15-20 minutes, not related to viewing the illuminated screen, in compliance with the recommendations for relieving stress from the visual analyzer.
