A hygienic estimation of the actual average daily dose (AADD) of iron, consumed by the adolescent population with the sources of its per oral administration in human bodies in the conditions of iron excess (0.8 mg/l) in tap water has been performed. An object of the study was a random sample of 156 schoolchildren aged 14-17 years from Vladivostok. Methods: all adolescents were interviewed with use of a questionnaire that included questions about daily consumption of tap water, bottled water, 21 food products and dishes. Iron concentration in food and drinking water was determined according to the reference tables and laboratory findings. Results: the harmless levels of AADD of iron for adolescent health (about 17 mg/day) were stated. An occurrence frequency of iron consumption deficiency was equal to 28.08 (boys) and 58,54 (girls) cases per 100 adolescents. Conclusions: against iron excess in tap water according to the organoleptic limiting sign of iron content harmfulness (up to 2.7 MPC), iron consumption deficiency is formed by lower intake of high bioavailable iron sources: eggs, fishes (girls), eggs, sausage products and animal meat (boys).

Cervical cancer is an important public health problem. The incidence of cervical cancer in the world is 10.6 per 100,000 women. Often in the literature, cervical cancer is called a disease of inequality due to a significant difference in the morbidity and mortality rates between the developed and developing countries. In Russia, the mortality and incidence rates of cervical cancer do not tend to a decrease. High prevalence of human papilloma viral infection, lack of organized screening, an organized cytological registry and quality-controlled cytology can be the reasons of the low success rate in implementation of cervical cancer prevention programs. There is a need of studies of human papilloma virus (HPV) prevalence in Russia, a need of national screening programs, development of laws regulating use of HPV vaccine.

The aim of this study was to assess the level of psychoemotional stress and its association with eating behavior in the town of Turkestan, Southern Kazakhstan. Turkestan region is considered as one of the most unfavourable regions in Kazakhstan with poor ecologic conditions. Altogether, 637 individuals from the population served by the policlinic of the International Kazakh-Turkish University participated in a cross-sectional study. The level of stress was assessed using the Perceived Stress Scale-10 questionnaire. Eating behavior was assessed using the Dutch Eating Behaviour Questionnaire. Multinomial logistic regression models and multivariable linear models were applied to study associations between stress and eating behavior. The prevalence of light, moderate and intensive stress was 38.5 %, 50.2 % and 11.3 %, respectively. The prevalence of restrictive, emotional and external types of eating behavior was 30.3 %, 37.5 % and 32.2 %, respectively. We observed positive and statistically significant association between the level of stress and external type of eating behavior. Moreover, eating behavior was also associated with gender, age and education.

The purpose of this study was to investigate biological properties of S. aureus isolated from a poultry plant staff, birds and bacteria carriers. Almost all the isolates of S. aureus had a number of virulence factors. All strains of S. aureus were characterized by an ability to form biofilms. In spite of the fact that individual values of biofilm biomass of different strains varied widely, there were no significant statistical differences between the mean values of these strains isolated from various sources. The study of antibiotic susceptibility revealed that the cultures isolated from bacteria carriers were sensitive to a wide spectrum of antibacterial agents. At the same time, strains isolated from the birds and a number of strains isolated from the staff were resistant to antibacterial agents used in poultry keeping. Almost all the isolates of bacteria carriers were lysed by typical bacteriophages of the "H" set ("Human"). Most of the isolates from the birds and the third part of the staff-strains were not sensitive to bacteriophages. The cultures isolated from the bacteria carriers belonged to the Ekovar A ("Human"). Some strains isolated from the birds and the poultry farm staff also belonged to this Ekovar, while most of the "bird" S. aureus cultures belonged to the Ekovar B ("Chicken"). Thus at the poultry farm, there was observed an exchange of S. aureus strains among the staff and the birds.
