COMPREHENSIVE EVALUATION OF THE NATURAL TULAREMIA FOCUS IN THE CONFLUENCE OF IRTYSH AND OB RIVERS
Objective of the study is to conduct the complex investigations aimed at identification of circulation pathways of tularemia agent, as well as to define the main carriers and vectors of the disease. Materials and methods. Trap trench method, trap fences and trap-lines were used to catch small mammals for examination. Bacteriological testing on tularemia infection in animals was carried out using spleen samples. In addition, water samples were studied. Results and conclusions. In 2015, performed were complex zoological-parasitological and bacteriological studies aimed at identification of circulation pathways of tularemia agent in the natural focus of floodplain-river type in the Khanty-Mansiysk Autonomous District – Yugra, in the confluence of Irtysh and Ob rivers. The total volume of the material tested was 542 specimens of small mammals of 16 species and 447 specimens of amphibians belonging to 4 species. It was established that, compared to 2013, zoocoenosis restructuring in the floodplain habitats occurred. The main carrier and a massive source of tularemia infection – the water vole – was excluded from the small mammals’ community. Also, ectoparasites composition changed; no specific ectoparasites of the water vole were to be found. In 2015, in the confluence of Irtysh and Ob rivers, lukewarm epizooty among the small mammals was observed. Essential for the occurrence of acute tularemia epizooty prerequisites were absent

[Analysis of the results of epidemiological study on prevalence of erectile dysfunction in the Russian Federation].
With the aim of evaluation of prevalence of erectile dysfunction (ED) and other violations of the sexual function of men in the Russian Federation, anonymous questionnaire survey of 1400 men was performed. The study involved seven centers located in the most densely populated regions of the country. 1225 questionnaires were analyzed. It was found that ED symptoms were present in 1101 (89.9%) respondents. Age-related symptoms (by AMS questionnaire) were detected in 554 (45.2%) patients, most of whom were aged 45-59 years. The importance of active detection of ED in men, as it can be one of manifestation of a more serious disease, was demonstrated
Блохи (Siphonaptera) мелких млекопитающих северной тайги Западной Сибири
The purpose of the research is to identify the composition of fleas, and infection rates in small mammals in the northern taiga of Western Siberia; and to summarize information on fleas in the studied area. Materials and methods. In 2008, 2010, and 2016–2021, records of small mammals and their ectoparasites (fleas) were made in the northern taiga of Western Siberia. Parasitological survey was performed for 1363 specimens of insectivores and rodents of 13 species that were recorded using trap trenches, drift fences and trap-lines. A total of 1524 fleas of 18 species were recorded. Indices widely accepted in parasitology were used to assess quantitative indicators of fleas. Results and discussion. Based on the results of our own research and literature sources, small mammals in the northern taiga of Western Siberia were found to have specimens of 28 flea species. The flea fauna of the study area was represented by shrew fleas (Corrodopsylla birulai, Palaeopsylla sorecis), bird fleas (Ceratophyllus gallinae, C. garei), and specific species (Ceratophyllus anisus, C. indages, C. sciurorum, Megabothris walkeri, Leptopsylla segnis). Peromyscopsylla silvatica, Corrodopsylla birulai, Megabothris rectangulatus, Amalaraeus penicilliger, and Amphipsylla sibirica comprise the backbone of the flea fauna of small mammals in the northern taiga of Western Siberia.Цель исследований – установить состав блох, показатели заражения ими мелких млекопитающих северной тайги Западной Сибири; обобщить сведения по блохам изученной территории. Материалы и методы. В 2008, 2010, 2016–2021 гг. в северной тайге Западной Сибири проведен учет мелких млекопитающих и их эктопаразитов (блох). Паразитологической оценке подвергнуто 1363 особи насекомоядных и грызунов 13 видов, учтенных с помощью ловчих канавок, направляющих заборчиков и ловушко-линий. Всего зарегистрированы 1524 блохи 18 видов. Для оценки количественных показателей блох использованы общепринятые в паразитологии индексы. Результаты и обсуждение. По результатам собственных исследований и литературных источников у мелких млекопитающих в северной тайге Западной Сибири установлено обитание представителей 28 видов блох. Фауна блох изученной территории представлена блохами землероек (Corrodopsylla birulai, Palaeopsylla sorecis), блохами птиц (Ceratophyllus gallinae, C. garei), специфическими видами (Ceratophyllus anisus, C. indages, C. sciurorum, Megabothris walkeri, Leptopsylla segnis). Основу фауны блох мелких млекопитающих северной тайги Западной Сибири составляют Peromyscopsylla silvatica, Corrodopsylla birulai, Megabothris rectangulatus, Amalaraeus penicilliger и Amphipsylla sibirica
[Determinants of risk of the development of erectile dysfunction in the Russian Federation: analysis of epidemiological studies].
According to the results of epidemiological studies of prevalence of erectile dysfunction in the Russian Federation, the search for the determinants of risk of its development was performed. It was found that the leading risk factors for the development of erectile dysfunction, in descending order of statistical significance, include the amount of accumulation of points according to the IPSS score, arterial hypertension, L(IPSS) quality of life index, age, diabetes, and overweight and obesity
