In order to develop approaches to prevention of organizational stress (OS) in law enforcement officers, 155 police officers have been examined. It has been revealed that one third of them had a high level of OS and were characterized by low adaptive capacity, signs of psychological maladjustment, symptoms of professional burnout. Basic principles for prevention of OS in law enforcement officers with separation of professional-organizational, social and individual-psychological areas of work contributing to formation of their high psychological stability have been grounded.

The growing incidence of child cancer in the Republic of Dagestan testifies troubled environmental situation. This is why it is critical to define dependence between child cancer incidence and impact of environmental factors in the Republic's regions with troubled environmental conditions. In this study for the first time, we have conducted a comprehensive medical and ecological monitoring and an analysis of the total child cancer incidence in the Republic of Dagestan based on our multiyear data. The key methods of used research were a routine and look back analysis of the regional health indicators, the cartographic method, mathematic and cartographic modeling and the methods of medical and geographical analysis. We have identified epidemiological peculiarities of the child cancer incidence. A cartographic document has been made to show a geographic association of child cancer with different regions and towns of the Republic. Ecological, geographical and epidemiological assessment based on mathematical and cartographic modeling made it possible to divide the territory of the Republic into districts according to the degrees of environmental problems and to forecast the child cancer incidence. The results of this research can be used in working out a policy and strategies in the field of social and economic development, environmental monitoring and the healthcare system in the Republic of Dagestan; they will help to develop scientifically based recommendations for cancer prevention important for the Republic's districts, which can be used by the Dagestan Ministry of Health institutions to screen the children's health status.

Changes of static and dynamic indicators of the external breath function during local cooling of the hand and foot skin in 30 young men and 30 girls aged 18-24 years which were born and constantly lived in the European North of Russia has been studied. The study was carried out with the ergospirometry system Oxycon Pro. At the initial stage, the indicators of functional state of external breath were estimated with the spirography. The following stage consisted of carrying out local cooling of the hand skin. The examinee put down a hand for 1 minute in a vessel with water which temperature successively was 24° С, 15° С and 8° С. Right after cooling repeated spirography was performed. The restoration interval between the tests was 25-30 minutes. In the same sequence, cooling of feet was carried out, and spirography was performed. It has been established that local cooling significantly influenced some indicators of external breath. Thus during cold impact on the skin peripheral thermoreceptors both of the hands and feet of the girls, a statistically significant increase in the respiratory minute volume (RMV) and respiratory rate (RR) indicators was observed, and in the young men, similar reactions were revealed only during feet cooling. During cooling of the young men's hands, only the RR value increased significantly, while the maximal breathing capacity (MBC) values and the breathing reserve (BR) values significantly decreased. Besides, a decrease in the RR indicators during cold impact on the foot skin in the young men was observed.

On the basis of a comparative analysis depending on a disease stage, there have been given the results of treatment of 42 patients with osteoarthrosis of the knee joint with the method of local injection therapy. The patients were treated on an outpatient basis by an orthopedist. It has been found that the best improvement results have been reached at the I stage of OA in 94.7 % of the patients, the results were slightly worse at the II stage - in 83.3 % and at the III stage - in 60.0 % of the patients. The patients did not show deterioration of the clinical picture of the knees' state, but in 14.3 %, a positive role of this type of treatment has not been subjectively established. Undoubtedly, that was due to the existing orthopedic pathologies of the knee joint - contractures, presence of chondromatosis, the changing axis of the extremity, degenerative-dystrophic changes of the menisci and the articular cartilage, state of the periarticular tissues. Thus, local injection therapy in patients with osteoarthritis of the knee takes an important place in the system of complex treatment. To a greater extent, it is indicated for treatment at the I and II degrees of gonarthrosis due to its maximum efficiency. At the III degree of gonartrosis, there are increased indications for operative treatment - knee arthroplasty.

We have studied the prevalence and socio-demographic determinants of anemia and also have investigated associations between anemia and metabolic syndrome in Turkestan, Southern Kazakhstan region, Kazakhstan. Southern Kazakhstan is one of the regions with the lowest level of incomes. The sample consisted of 839 patients from the polyclinic of the International Kazakh-Turkish University. The overall prevalence of anemia was 26.4 %. The highest prevalence of anemia was observed among women (30.4 %) and in the age group 30-39 years (39,0 %). A multiple logistic regression was performed to study independent associations between the studied factors and development of anemia with and without adjustment to other socio-demographic factors. The odds of anemia in persons from the oldest age category is 5 times lower than in the younger age categories. Odds of anemia in men by 2.4 times less compared to women. A multiple linear regression was used to study associations between hemoglobin levels and socio-demographic factors. There were statistically significant relationship between hemoglobin levels and age (β = 5.85; 95 % CI: 1.63; 10.06), between hemoglobin level and gender (β = 21.50; 95 % CI: 19.12 ; 23.89). Also, was found statistically significant interaction between the presence of metabolic syndrome and the level of hemoglobin after adjustment for all socio-demographic factors ((β = 3.12; 95 % CI: 0.53; 1.32).
