Climate warming in the Arctic may increase the risk of zoonoses due to expansion of vector habitats, improved chances of vector survival during winter, and permafrost degradation. Monitoring of soil temperatures at Siberian cryology control stations since 1970 showed correlations between air temperatures and the depth of permafrost layer that thawed during summer season. Between 1900s and 1980s, the temperature of surface layer of permafrost increased by 2–4°C; and a further increase of 3°C is expected. Frequent outbreaks of anthrax caused death of 1.5 million deer in Russian North between 1897 and 1925. Anthrax among people or cattle has been reported in 29,000 settlements of the Russian North, including more than 200 Yakutia settlements, which are located near the burial grounds of cattle that died from anthrax. Statistically significant positive trends in annual average temperatures were established in 8 out of 17 administrative districts of Yakutia for which sufficient meteorological data were available. At present, it is not known whether further warming of the permafrost will lead to the release of viable anthrax organisms. Nevertheless, we suggest that it would be prudent to undertake careful monitoring of permafrost conditions in all areas where an anthrax outbreak had occurred in the past.

In this study, the prevalence of EA across different regions of the Russian Federation was analyzed. The prevalence of EA in the period under study remained stable, and the relative risk of EA was associated with maternal age, birth weight and gravidity.

This article presents the results of analysis of mortality dynamics among population of 9 territories of Arctic and Subarctic regions, using linear regression technique. All-cause mortality reduction was significantly greater in the 4 territories of the country. These 4 regions were: Murmansk region and Komi Republic (for females), Archangelsk region (for both sexes) and Republic Sakha (Yakutia) (for males). The following regions displayed mortality reduction which was close to national averages or less: YaNAO, KhMAO and Magadan region. Mortality rates among males declined faster than that among females. Relatively lower mortality indicators in the territories of YaNAO and KhMAO could likely be attributed to migration of the population to mid-latitude regions with accumulated burden of northern pathology. Mortality reduction tendencies from the leading death causes (diseases of circulatory system, respiratory diseases, external causes) in the region are close to national averages. The most strongly mortality reduced from brain strokes, myocardial infarction and external causes of death. The mortality rates and the mortality dynamics can be described as relatively positive in the region on the whole, except for "other diseases of circulatory system" category, where mortality rates exceeded national average twice in particular years. Life expectancy in the Arctic region is close to that in Russia, except two autonomous regions - Khanty-Mansiisky and Yamalo-Nenetsky, where life expectancy was higher than national average by 1.7 and 2.6 years among males and by 0.4 and 0.7 years among females, respectively. The situation in Nenetsky and Chukotsky Autonomous Regions and in Magadan region remains unclear because of possible inaccuracy of primary data.

Omphalocele is a congenital malformation belonging to the group of abdominal wall defects. Objective. To determine the incidence of omphalocele and analyze its dynamics for the period 2011–2018 in the regions of the Russian Federation according to monitoring data of congenital anomalies. Materials and methods. Statistical analysis of omphalocele cases among newborns and fetuses with malformations for the period 2011–2018 in 22 regions of the Russian Federation was carried out. The incidence of malformations was calculated per 10,000 births. Results. A total of 1,073 cases of omphalocele were reported from 2011 to 2018, of which 69.34% were in fetuses eliminated due to the prenatal detection of malformation, 27.03% – in liveborn fetuses, and 3.63% – in stillborn fetuses. The male to female ratio was 1.56:1. The overall incidence of omphalocele was 2.95 (95% CI 2.77– 3.13) and the incidence among newborns excluding fetuses was 0.9 per 10,000 (95% CI 0.81– 1.01). There was a statistically significant positive time trend in the dynamics of the overall incidence of omphalocele between 2011 and 2018. Conclusion. The evaluation of the incidence of severe malformation – omphalocele – was obtained in different regions of the Russian Federation for the first time. The incidence of this malformation tended to increase over the study period. Male gender and maternal age over 35 years can be considered as risk factors. These results can be used in planning preventive measures. Key words: congenital malformation, monitoring, newborns, omphalocele, fetuses, incidence, epidemiology

Purpose. The study aims at assessing and analyzing the prevalence of congenital malformations in the Republic of Sakha (Yakutia) based on the data from birth defects surveillance from 2012 to 2019.Material and methods. The data of congenital malformations monitoring in the Republic of Sakha (Yakutia) for 2012–2019 are analyzed. There were revealed 1104 cases of congenital malformations of obligate registration. The total number of births was 122,413. The prevalence of birth defects was calculated per 10000 births.Results. The prevalence of congenital malformations in the Republic of Sakha was obtained. The analysis of the dynamics of the congenital malformations prevalence has been carried out. No changes in the birth defects prevalence for the analyzed period have been shown.Conclusion. Regional monitoring makes it possible to obtain and analyze congenital malformations prevalence.
