In the first one and a half decades of the 21st century, there is observed an intensive development of the medical prevention in health care facilities. New preventive treatment facilities and subdivisions were created and a new feature - preventive counseling was imputed to a wide range of doctors. This work included the evaluation of the preventive activity, lifestyle and health state of 221 health care providers, analysis of results of the preventive check-up of 154 nurses and analysis of the workplace assessment of 200 health workers. The results of the work showed just doctors to perform most of the preventive health care for patients. Only half of the surveyed physicians and one third of nurses noted that they gained knowledge about medical prevention in the process of training in a medical school. Most health care providers stated that they keep a healthy lifestyle. At once, a quarter of surveyed nurses answered that they smoke and more often do it at work. It should be noted that there was much less smokers among doctors. Nurses and doctors justified the cause of smoking by to the necessity to relieve work-related stress. A large part of health care providers noted a lack of physical activity, poor diet and insufficient sleep. An objective assessment of working conditions based on the analysis of workplaces assessment showed the increased work intensity and low lighting at the workplace of health care providers. Based on the findings it can be concluded health care providers to be motivated to perform work on preventive medicine. However, the training of physicians and nurses in the field of health lifestyle promotion and disease prevention requires the improvement. The personal commitment of health workers to the disease prevention for their own health preserving cannot be considered to be sufficient. A comprehensive approach to the training of health professionals and the organization of their work will allow to enhance of the professional activity health of care providers in the field of the disease prevention and improving their health.

150 years ago D. I. Mendeleev revealed the Periodic law to the world and since that time periodic dependencies have been increasingly used in various fields of basic and applied sciences. For the first time we consider the regularities of periodic dependences of the concentration of chemical elements in the ash residue of human hair on the number of the element. Such dependencies for various regions of Russia reveal strictly individual character. It is shown that distributions of the chemical elements for men and women also differ, as well as the distributions determined for the same groups in inhabitants of different regions of residence and depend to a significant extent on the genetic and physiological characteristics of human organism, variability of environmental conditions, earlier diseases and other impacts. This means that population of different urban regions (e.g., Siberian region) is characterized by a strictly individual distribution of biogenic elements. A hypothesis has been put forward that extrema observed on the studied dependences can be a kind of code for a given locality, reflecting correlation with various factors of genetic and ecological nature.

The article presents the analysis of the influence of specific professional activities of nurses on their health, quality and productivity when conducting diagnostic testing of patients. We studied the activities and structure of time expenditures of nurses when performing the medical diagnostic testing of patients under their specific operating conditions. The incidence and severity of clinical and functional disorders in nurses that result in reduced physical functioning, emotional state and quality of their professional activity, were studied. Using a dedicated questionnaire (“Professional Burnout (MBI)”), the severity and prevalence of the components of the emotional burnout syndrome was studied. Organizational and preventive measures to optimize their working conditions have been proposed. The developed method of integral evaluation of the performance quality and efficiency has been presented, as well we the process approach model of professional activities of nurses engaged in diagnostic testing of patients.

The creation of the Early Intervention Service as a structural unit of educational, medical or social welfare institutions in the Chuvash republic territory is especially in demand due to the preservation of the number of children with disabilities. The article discusses a model for constructing an early intervention system in the Chuvash Republic in terms of vertical and horizontal structure. The vector of work of the Early Intervention Service is the consolidation of the professional forces of principals and employees of educational institutions, organizations of the social protection and health care system, socially oriented nonprofit organizations, nongovernmental organizations and public associations. An interdisciplinary team that provides early intervention to clients of the target group, includes, as equal partners, representatives of the Orthodox, secular and professional community of various Ministries and departments, and the parent community. The content of the Early Intervention Service is the implementation of a comprehensive system of medical-psychological and socialpedagogical support for young children with disabilities and their parents, creation of a new active environment with high adaptive potential in the social space. This environment should activate inter-subjective (communication, patronage, cooperation), intra-subjective (resilience, semantic disposition) and non-subjective (sociocultural and physical environment) potentials and development resources of each subject included in the activities of the Early Intervention Service (children with disabilities, their parents, specialists). A generalization of the experience of the activities of the Early Intervention Services, organized and functioning on the territory of the Chuvash Republic made it possible to identify complex-parallel, sequentially-integrative, complex-collegial and collegiallyintegrative options for the implementation of integrated support. It has been established that the comprehensive-collegial and collegial-integrative options most fully meet modern requirements for organizing comprehensive support for the development process of children with disabilities and their parents in the Early Intervention Service. The purpose of this study was to study a regional version of the organization and functioning of the Early Intervention Service in the Chuvash Republic, models for the provision of comprehensive specialized medical, social, clinical, psychological, pedagogical support for atypical children and their parents.
