The study was carried out concerning complex evaluation of financial load of opportunistic screening of breast cancer. The data of established cases of breast cancer and stages of disease are taken from collections "The state of oncologic care in Russia" 2014, 2015 and 2016. The financial expenses for implementation of analog mammography, sonography and physician's examination are taken from "The territorial tariff agreement 2014". The evaluation of X-ray finds was implemented using categories BI-RADS (Breast Imaging Reporting and Data System) proposed by the American College of Radiology. During 2014, in the Primorskiy Krai 40,825 of diagnostic and 50,824 cases of preventive mammography were implemented. In 2015 43,196 diagnostic and 58,567 preventive examinations and in 2016 47,359 diagnostic and 53 973 preventive examinations were implemented correspondingly. According the Foundation of mandatory medical insurance, the price of analog mammography made up to 292 rubles. The social financial load of diagnostic of a single case of breast cancer at stage T1 made up to 96,367 rubles in 2014, 90,966 rubles in 2015 and 73,303 rubles in 2016 correspondingly. The analysis of detection of breast cancer at early stage T1 and financial costs of early diagnostic demonstrated a distinct trend of decreasing of financial load at diagnostic of a single case of breast cancer of T1 during 2014-2016 at the expense of amelioration of quality of description of picture and training of radiologists. The model was proposed to form groups of higher risk with subsequent detailed examination and implementation of opportunistic screening in the group of common level of risk of development of breast cancer as a most perspective and less unprofitable one.

The article presents the results of comparative evaluation of health of students of I-III courses of the Pacific State Medical University during process of education. The study used data of sociological analysis (questionnaire survey) with evaluation of subjective attitude of students to personal health, work-rest regime and health risk factors. The analysis of general morbidity with temporary disability in 2014-2017 was implemented. The indices of physical development of medical students such as index Ketle (body mass-body height indicator), indicator of lungs vital capacity, power indicator (wrist dynamometry). The average indices specific to particular gender height groups of medical students are calculated. It is established that health of students of I-III courses is affected by a complex of such factors as education process, earning additionally after studies, low interest to physical culture and sport and harmful habits. The subjective evaluation by medical students their own health using a questionnaire survey technique testifies that out of number of risk factors negatively affecting students' health the most significant are harmful habits, wrong planning of recreation regimen and sedentary style of life. The evaluation of health state of students established a trend to increasing of morbidity with prevalence of diseases of respiratory organs in its structure. Hereinafter, the results of study can be applied for establishment of directions and development of preventive measures related to health promotion and healthy life-style formation in medical students.

The article presents the data of implemented in 2017 re-monitoring of prevalence of main forms of gastroduodenal pathology among 471 schoolchildren aged from 7 to 17 years in rural territory of the Republic of Tyva being a territory of extremely high morbidity of carcinoma of stomach of adult population, especially indigenous one. It is established that negative dynamics of prevalence of dyspepsia syndrome, a main clinical manifestation of pathology of stomach and duodenum observed during previous monitoring is absent among examined children. At that, among Caucasian schoolchildren there is an increasing of its rate as compared with data of analogous monitoring i 2008-2009. Besides, clinical course of dyspepsia has been changed: a pain alternative is marked more rarely in children of both populations. The positive result of monitoring of children of Tyva in 2017 is disappearance of cases of peptic ulcer from the structure of gastroduodenal pathology in indigenous residents. At that, on the whole in children no significant dynamics of structure of diseases of stomach and duodenum were detected. The results of monitoring testify positive dynamics in prevalence of gastroduodenal pathology in schoolchildren of the Republic of Tyva. The monitoring permits to obtain reliable data of prevalence of gastroduodenal pathology and main tendencies in their dynamics. The implementation of data collection and analysis of effecting social ecological factors during monitoring application will increase efficiency of prevention.

The purpose of study. To evaluate indices of morbidity and mortality of various types of strokes in the cohort of workers of the nuclear industry enterprise of the Ural Federal Okrug exposed to occupational prolonged irradiation. Materials and methods. The study was carried out in the cohort of 22,337 workers (25% of females) of the production association "Mayak" hired in 1948-1982 on the basis of medical dosimetry data base "Klinika" and data base "The Dosimetry System for Workers of the Production Association "Mayak" - 2008" The intensive (crude) indices and standardized indices of morbidity and mortality per 1,000 man-years were calculated. Results. The number of cases and deaths included in analysis made up to 2533 and 797 correspondingly. The most frequently occurring type of stroke is brain infarction. The largest number of cases and deaths of stroke (69% and 81% correspondingly) was registered in individuals aged older than 60 years. The results of implemented study demonstrated that morbidity and mortality of stroke in the analyzed cohort of workers depended on gender, age and calendar period. Conclusions. Because cerebrovascular diseases are one of the main causes of mortality and permanent disability of population of Russia, the results of study of unique cohort will input into analysis of epidemiology of cerebrovascular diseases. Alongside with the results of other large studies they can become a basis of development of preventive programs targeted to decreasing of morbidity and mortality of cerebrovascular diseases, including contingents working in contact with sources of ionizing radiation.

The article presents the results of complex hygienic and physiological studies of conditions of labor of workers of chemical industry. The age and seniority determinacy of health disorders. The alterations of cardio-vascular, nervous systems, ENT-organs, musculoskeletal system and connective tissue are established. In workers of main group unidirectional alterations are established concerning indices of peripheral blood characterized by anemic syndrome, neutrophil leukocytosis, lymphocytosis, eosinophilia and expressed thrombocytopenia.

The terms "performance" and "effectiveness" are frequently used in many national biomedical studies as synonyms. However, they have different significance and their inappropriate application often provide no possibility to evaluate properly this or that type of activity and results in difficulties of their comprehension.
