ORGANIZATION OF PROPHYLACTIC SCREENING OF PATIENTS WITH ONCOLOGICAL DISEASES

Aim - to substantiate the measures aimed at improvement of the prophylactic screening of patients with oncological diseases, and to estimate the effectiveness of these measures. Materials and methods. The materials of the study were the data of the extracts from medical records (a personal patient’s card from the outpatient department, a control card of the dispensary patient, a questionnaire). The statistical processing of the material was carried out using parametric methods, with the determination of the confidence interval at a probability of 95.0%. Results. The study revealed that the implementation of measures aimed at improving medical care in outpatient settings led to the following results: the proportion of identified diseases in the IV stage of the disease decreased from 20.8% in 2010-2012 to 15.0% in 2013-2015; the one-year mortality rate decreased from 28.1% to 18.3%; the five-year survival rate increased by 5.2%; the number of oncologist’s consultations increased from 3.6 to 6.3%. It was established that those patients who follow doctors’ recommendations, regularly visit oncologists and other medical specialists, attend health schools, and keep a healthy lifestyle in comparison with the patients who do not follow the treatment regimen, consume alcohol, and refused from subsidized pharmaceutical provision less likely have progression of the disease (22.5% and 62.0%), lethal outcome (18.6% and 23.0%), and disability (65.4% and 85.0%). Conclusion. It was established that compliance with the recommendations of doctors and adherence to a healthy lifestyle led to the decrease in the lethality, disability and progression of the oncological disease

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the 21st century

During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental changes that can have global consequences. The Northern Eurasia Future Initiative (NEFI) has been designed as an essential continuation of the Northern Eurasia Earth Science Partnership Initiative (NEESPI), which was launched in 2004. NEESPI sought to elucidate all aspects of ongoing environmental change, to inform societies and, thus, to better prepare societies for future developments. A key principle of NEFI is that these developments must now be secured through science-based strategies co-designed with regional decision makers to lead their societies to prosperity in the face of environmental and institutional challenges. NEESPI scientific research, data, and models have created a solid knowledge base to support the NEFI program. This paper presents the NEFI research vision consensus based on that knowledge. It provides the reader with samples of recent accomplishments in regional studies and formulates new NEFI science questions. To address these questions, nine research foci are identified and their selections are briefly justified. These foci include: warming of the Arctic; changing frequency, pattern, and intensity of extreme and inclement environmental conditions; retreat of the cryosphere; changes in terrestrial water cycles; changes in the biosphere; pressures on land-use; changes in infrastructure; societal actions in response to environmental change; and quantification of Northern Eurasia's role in the global Earth system. Powerful feedbacks between the Earth and human systems in Northern Eurasia (e.g., mega-fires, droughts, depletion of the cryosphere essential for water supply, retreat of sea ice) result from past and current human activities (e.g., large scale water withdrawals, land use and governance change) and potentially restrict or provide new opportunities for future human activities. Therefore, we propose that Integrated Assessment Models are needed as the final stage of global change assessment. The overarching goal of this NEFI modeling effort will enable evaluation of economic decisions in response to changing environmental conditions and justification of mitigation and adaptation efforts

Redescription of the Antarctic springtail Desoria klovstadi using morphological and molecular evidence

Isotoma klovstadi Carpenter, 1902 was one of the first Collembola described from the Antarctic continent. It was first collected in November 1899 during the British Antarctic Expedition on the north coast of Victoria Land in the Ross Sea region. It is now known to occur in an extensive area of northern Victoria Land, including the offshore Possession, Coulman, and Foyn Islands. More recently, L klovstadi was moved to the genus Gnathisotoma Cassagnau, 1957 and has been included in this genus in an unpublished checklist (online) of all described Collembola. Here, we redescribe the species and use morphological and molecular (COI and 18S genes) evidence to investigate its affinities within the Isotominae. We show that it does not belong to Gnathisotoma, or Isotoma s. str. (the viridis group) as currently conceived, but is likely to be part of the species complex of Isotoma s. lat. We discuss reasons for placing it in the genus Desoria Nicolet, 1841. Our results reinforce the already high level of endemicity in the Antarctic fauna and emphasise the value of both morphological and molecular studies in examining relict Gondwanan taxa and their evolutionary relationships with those of other Southern Hemisphere continents
