Small business development and resource use in Russian regions
Relevance. The living standards in any country largely depend on how developed is this country’s business sector. The latter, in its turn, relies on the availability and efficient use of resources. The problem that arises in this respect and that this study seeks to address is how to measure the resource potential available for the development of small businesses in order to choose the optimal strategy of stimulating this sector for this or that region.Research objective. The aim of this research is to study resources available to small businesses and their use in Russian regions.Data and methods. The set of indicators used in our analysis helps us measure the activity of small businesses in Russian federal districts. The key elements of the assessment are based on the official statistics and include the following: average labor productivity of small businesses, the unit turnover per small enterprise, the number of small firms per 10,000 people. Each of these indicators was analyzed by using the methods of mathematical statistics according to the three criteria: stability (S); average values (M); and the variability of the results (V), which characterizes interregional differentiation within a federal district/country.Results. The article proposes a system of indicators for diagnosing small business development based on the concentration and performance of small-sized enterprises. The quantitative results of such analysis can be used for choosing strategies of small business development.Conclusion. There was a significant decline in entrepreneurial activity during the post-crisis period of 2017-2018 in Russia, which could be explained by the impact of foreign sanctions and the difficult economic situation in the country (inflation, a sharp rise in the price of resources, difficulties in communication with international partners, and the difficulty or even impossibility to adopt efficient technologies in a short time). As our analysis has shown, some of the Russian territories still have underutilized resource potential that can be used for stimulating small business development
Clinical and laboratory characteristics of influenza infection in hospitalized adult patients during the 2018-2019 epidemic season
Despite the success in prevention and therapy, influenza remains a mass disease with mortality rate up to 0.01—0.2% worldwide.Purpose. Conducting clinical and laboratory analysis of influenza infection cases and evaluating their etiological significance in adult hospitalized patients during 2018—2019 epidemic season. Materials and methods. There were analyzed 569 case histories of patients hospitalized at the Clinical Infectious Diseases Hospital named after S.P. Botkin. Patients were examined by PCR that resulted in verified influenza virus in 260 cases. Nasopharyngeal swabs collected from 36 patients were examined by virological method on MDCK cell culture. 24 influenza virus strains were isolated and identified.Results. The study allowed to identify a viral landscape represented by influenza viruses A and B found in 98.5% and 1.5% cases, respectively. Influenza viruses isolated on cell culture in 50% of cases were identified. Among the influenza viruses isolated on cell culture there were identified serotype A influenza viruses (H1N1) closely related to the pandemic influenza A (H1N1)pdm09. Some isolates (41.7%) belonged to serotype A (H3N2), which were related to strain A/Singapore/16-0019/16. Influenza B virus strain of the Victoria lineage isolated from a hospitalized patient possessed a triple deletion in hemagglutinin gene, which antigenic properties substantially differed from those of the influenza virus strain being included into current influenza vaccines. Upon admission, the condition of most patients was estimated as moderate (males — 48.7%, females — 51.3%). The median patient age was 35 years old, with comorbidities being registered in 50% cases. The clinical picture for 2018—2019 seasonal influenza displayed no distinctive features as compared to previous epidemic seasons. The duration of intoxication and catarrhal syndrome was 4.3±0.13 and 6.9±0.29 days, respectively, with median body temperature ranging within 39.2±0.06°С. All patients received standard pathogenetic therapy. Complications were noted in 86.7% cases such as pneumonia — 11.1%, sinusitis — 6.9%, bronchitis — 56.9%. The bed day length was 5.93±0.29, no lethal outcomes were recorded.Conclusion. It was found that influenza A viruses were dominant in patients observed comprising up to 98.5% cases, whereas influenza viruses B were found in as few as 1.5% patients. The clinical picture was characterized by severe intoxication and catarrhal syndrome, being frequently associated with complications

Уровень жизни в любой стране во многом зависит от того, насколько развит деловой сектор этой страны. Последнее, в свою очередь, зависит от доступности и эффективного использования ресурсов. Проблема, которая возникает в этой связи и которую пытается решить данное исследование, заключается в том, как измерить ресурсный потенциал, доступный для развития малого бизнеса, чтобы выбрать оптимальную стратегию стимулирования этого сектора для того или иного региона. Цель исследования. Целью исследования является изучение ресурсов, доступных малому бизнесу, и их использования в регионах России. Данные и методы. Сформированная в работе серия относительных индикаторов направлена на выявление активности малого бизнеса по федеральным округам страны. Базовыми элементами оценки на основе данных официальной статистики выступают: средняя производительность труда в малом бизнесе, удельный оборот на одно малое предприятие, число малых фирм на 10000 населения. Каждый из указанных индикаторов проанализирован с помощью применения методов математической статистики по 3-м критериям: устойчивости (S); средним значениям (M); вариативности результатов (V), отражающей степень межрегиональной дифференциации в пределах Федерального округа/страны. Результаты. В работе предложена система показателей для диагностики деятельности сектора малого предпринимательства на основе системы показателей «концентрация-эффективность» и их статистических характеристик. Количественные значения полученных результатов служат основой для выбора направлений развития малого бизнеса в конкретной социально-экономической системе. Выводы. В посткризисный период 2017–2018 гг. в России наблюдался значительный спад предпринимательской активности, что можно объяснить влиянием внешних санкций и сложной экономической ситуацией в стране (инфляция, резкое удорожание ресурсов, трудности в общении с международными партнерами, а также сложность или даже невозможность внедрения эффективных технологий в короткие сроки). Как показал проведенный нами анализ, на некоторых территориях России все еще имеется недоиспользованный ресурсный потенциал, который может быть использован для стимулирования развития малого бизнеса
Особенности клинического течения риновирусной инфекции у госпитализированных взрослых больных в эпидемический сезон 2017–2018 гг.
Purpose. Rhinovirus infection has in the past been perceived as a disease capable of causing mild respiratory symptoms in most cases in children. Modern clinical and epidemiological studies have shown that rhinovirus infection in adults and children and has a moderate and severe course. The aim of this study was to conduct a clinical and laboratory analysis of cases of rhinovirus infection in adult hospitalized patients and evaluate the etiological role of rinoviruses in the epidemic season of 2017/18.Materials and methods. 1013 case histories of patients admitted to the hospital with a diagnosis of SARS were studied. These patients were taken nasopharyngeal swabs were investigated by PCR for the detection of respiratory pathogens. A positive result was obtained with rhinovirus infection of 51 patients.Results. Of the examined patients, 41,6% had influenza, 45,8% had no viruses and 12,6% had other viral infections, of which 40% were due to rhinovirus infection. Among them, young patients prevailed: the median age for men was 31,0 years, for women-27,5 years. The disease occurred in a moderate form – 78,8%, severe course was observed in 5,3% of patients and was accompanied by infectious and toxic shock. Most often the disease occurred with complications acute bronchitis – 22,1%, pneumonia joined in 15,7% of cases.Conclusion. rhinovirus infection ranks first (40%) among non-influenza causes of viral respiratory tract infection in the examined patients. It was registered mainly in young people. In most cases, it proceeded in a moderate form and had a complicated course, including pneumonia.Цель. Риновирусная (РВ) инфекция в прошлом воспринималась как заболевание, способное вызывать легкие респираторные симптомы в большинстве случаев у детей. Современные клинико-эпидемиологические исследования показали, что РВ-инфекция у взрослых и детей имеет среднетяжелое и тяжелое течение. Целью настоящего исследования было проведение клинико-лабораторного анализа случаев риновирусной инфекции у взрослых госпитализированных больных и оценка этиологического значения риновирусов в эпидемический сезон 2017–2018 гг.Материалы и методы. Изучено 1013 историй болезни пациентов, обследованных методом ПЦР, из них 51 с РВ инфекцией.Результаты. Из обследованных больных у 41,6% выявлен грипп, у 45,8% вирусы не обнаружены и у 12,6% выявлены другие вирусные инфекции, из которых 40% приходится на РВ. Среди них преобладали пациенты молодого возраста: медиана для мужчин – 31,0 лет, для женщин – 27,5 лет. Заболевание протекало в среднетяжелой форме – 78,8%, тяжелое течение было отмечено у 5,3% больных и сопровождалось инфекционно-токсическим шоком. Заболевание наиболее часто осложнялось острым бронхитом – 22,1%, в 15,7% случаев присоединялась пневмония.Заключение. РВ-инфекция занимает первое место (40%) среди негриппозных причин вирусного поражения респираторного тракта у обследованных пациентов. Она регистрировалась преимущественно у лиц молодого возраста. В большинстве случаев протекала в среднетяжелой форме и имела осложненное течение, в том числе пневмонией.
Эпидемиологические и клинические характеристики острых респираторных инфекций в Санкт-Петербурге в эпидемические сезоны 2017–2018 гг. и 2018–2019 гг.
Objective: to analyze the epidemiological and clinical features of acute respiratory infections occurring during the St. Petersburg 2017–2018 and 2018–2019 epidemic seasons.Materials and methods: the study included 457 patients, treated in St. Petersburg clinics from 2017–2019, displaying symptoms of acute respiratory infection (ARI), including evaluation of their clinical histories. Pathogen types were determined by polymerase chain reaction (PCR). Data analysis was carried out using mathematical statistics methods using the Statistica 10 software package (StatSoft Inc.).Results: in this study, we examined the epidemiological and clinical features of acute respiratory infections in St. Petersburg occurring during two epidemic seasons, 2017–2018 and 2018–2019. The 2017–2018 season was characterized by a prevalence of infections caused by influenza B viruses and influenza A subtype H3N2 viruses. In the 2018–2019 season, there was a greater number of acute respiratory viral infections (ARVIs) and infections caused by influenza A subtype H1N1pdm; influenza B virus was detected only in isolated cases. In the 2017–2018 sore throats and muscle aches were a characteristic symptom of influenza A H1N1pdm infections, of bacterial infections – only sore throats. It was shown that throat pain and vasodilation of the scleral and soft palate vessels were significantly more frequent in the 2017–2018 season, compared to the 2018–2019 season. Cough and redness of the posterior pharyngeal wall were hallmark signs of ARVIs in the 2018–2019 season.Conclusion: according to the data, each epidemic season is characterized not only by its own type-specific acute respiratory infection frequencies, but also by different clinical manifestation frequencies. For global monitoring, treatment effectiveness evaluation, and refined study of acute respiratory infection clinical features, it is advisable to use approaches which incorporate accurate, specific, and rapid molecular biological methods capable of identifying a broad range of pathogens. Цель: сравнительный анализ эпидемиологических данных и клинических характеристик течения острых респираторных инфекций у больных в Санкт-Петербурге в эпидемические сезоны 2017–2018 гг. и 2018–2019 гг.Материалы и методы: в исследование включено 457 пациентов, находившихся на лечении в клиниках Санкт-Петербурга в 2017–2019 гг., с симптомами острых респираторных инфекций, проведен анализ эпидемиологических данных и клинических характеристик течения заболевания. Методом полимеразной цепной реакции определен вид патогена. Статистический анализ проведен с использованием методов математической статистики при помощи пакета Statistica 10, StatSoft Inc.Результаты. В сезон 2017–2018 гг. было характерно превалирование инфекций, вызванных вирусами гриппа В и А (H3N2). В сезоне 2018–2019 гг. было отмечено большее число случаев острых респираторных вирусных инфекций, в том числе гриппа, вызванного вирусом гриппа А (H1N1pdm); вирус гриппа В регистрировали в единичных случаях. Характерным симптомом в сезоне 2017–2018 гг. для гриппа А (H1N1pdm) были мышечные боли и боли в горле, для бактериальных инфекций – также боли в горле. Боли в горле и инъекции сосудов склер и мягкого неба достоверно чаще были отмечены в сезоне 2017–2018 гг. по сравнению с сезоном 2018–2019 гг. Кашель и гиперемия задней стенки глотки были характерными симптомами для ОРВИ в сезоне 2018–2019 гг.Заключение: рассмотренные два эпидемических сезона характеризовались не только различной частотой острых респираторных инфекций, но и различной частотой их клинических проявлений. Для глобального мониторинга, оценки эффективности лечения и более детального изучения клинических особенностей острых респираторных инфекций целесообразно использовать точные, специфичные и быстрые молекулярно-биологические методы с большим количеством определяемых патогенов.
КЛИНИКО-ЛАБОРАТОРНЫЙ АНАЛИЗ ЛЕТАЛЬНЫХ СЛУЧАЕВ ТЯЖЕЛОЙ ФОРМЫ ГРИППА А(H1N1) PDM 2009 ЗА ПЕРИОД ЭПИДЕМИИ 2015/2016 ГГ. В САНКТ-ПЕТЕРБУРГЕ
The purpose of our study was to investigate the characteristics of severe form of influenza A (H1N1) pdm 2009 with a fatal outcome, given the comorbidities. Materials and methods. Medical histories of 105 people who died in hospitals of St. Petersburg for the period of the epidemic of 2015/16 served as material for analysis.The lethality caused by the pandemic virus type A/ H1N1 / 2009 pdm was higher in males. Most of the patients had concomitant chronic diseases in the anamnesis. Obesity was observed in 44.8% (47/105) of patients, diabetes mellitus — 28.5% (30/105), isolated heart disease — 19.0% (20/ 105), combined pathology — 48.6% (51/105). In the first biochemical analysis of blood, creatine phosphokinase, lactate dehydrogenase were increased, total protein and prothrombin consumption index were reduced. The patient's death occurred after 5 days of illness in 88.6% cases, in 11.4% — up to 5 days of illness (inclusive). The analysis of fatal cases up to 5 days of a disease and death from complications (2—4 week) didn't find significant differences in the character and frequency of comorbidity. Specific antiviral therapy has been assigned to all patients, but 48 hours later.Bilateral subtotal viral and bacterial pneumonia was identified on the section, in the majority of cases, in 70.5% with hemorrhagic component. 30% patients had cerebral oedema, 41% patients had severe toxic parenchymatouse degeneration of miocardium, liver and kidneys. The pathology of the cardiovascular system, diabetes and obesity worsen the prognosis of the disease. Increased creatine phosphokinase, lactate dehydrogenase, and reduced total protein and prothrombin consumption index can be considered as markers of severe influenza. The ineffectiveness of antiviral therapy due to its late appointment, thus timely initiation of etiotropic treatment is very impotent. Целью нашего исследования было изучение особенностей течения тяжелой формы гриппа А(H1N1) pdm 2009 с летальным исходом у взрослых с учетом преморбидного фона. Материалом для анализа послужили истории болезни 105 человек, умерших в стационарах Санкт-Петербурга за эпидемию 2015/16 гг.Показано, что летальные случаи, обусловленные пандемическим вирусом типа А/Н1N1/ pdm 2009 чаще регистрировались у мужчин. В анамнезе у большей части пациентов были отмечены сопутствующие хронические заболевания. Сочетанная патология — 48,6% (51/105), ожирение — 44,8% (47/105), сахарный диабет — 28,5% (30/105), изолировано сердечно-сосудистая патология — в 19,0% (20/105) случаев. Зарегистрировано значимое повышение креатинфосфокиназы и лактатдегидрогеназы уже при первичном биохимическом анализе крови, а также снижение протромбинового индекса и общего белка. У большей части пациентов смерть наступала после 5 дня болезни (88,6%), у 12 (11,4%) пациентов — до 5 дня болезни (включительно). Достоверных различий между сопутствующей патологией у больных, умерших до 5 дня, и от осложнений (в течение 2—4 недель) не выявлено. На секции выявлялясь в большинстве случаев двусторонняя субтотальная вирусно-бактериальная пневмония, в 70,5% — с геморрагический компонентом, отек головного мозга (30%), тяжелая токсическая паренхиматозная дистрофия миокарда, печени, почек у 43 пациентов (41%). Специфическая противовирусная терапия была назначена всем пациентам, но позже 48 часов.Неблагоприятными факторами, ухудшающими прогноз заболевания, являются: патология сердечно-сосудистой системы, сахарный диабет и ожирение. Повышение ферментов креатинфосфокиназы, лактатдегидрогеназы, а также снижение протромбинового индекса и общего белка можно расценивать как маркеры тяжелого гриппа. Неэффективность противовирусной терапии обусловлена поздним ее назначением, что еще раз подчеркивает важность своевременного начала лечения этиотропными препаратами.
