PSYCHOLOGY OF CONSUMER CHOICE AND ITS INFLUENCE ON PRICING IN MARKET CONDITIONS

The schemes of the decision-making process of an individual when consuming various goods and services using the components of economic psychology have been considered. Relevant from the point of view of economic psychology characteristics of buyer behavior that have a direct impact on his attitude to the price level of a product or service and on his reaction when the price changes for them have been presented and reviewed. The used “models” of consumer behavior of motivation, explaining not only the purchase by him of this product, but also his decision to have this product have been shown. Building models of purchase motivation allows manufacturers not only to explain consumer behavior, but also to influence it. Knowing all these nuances and skilful use of them, manufacturers have the opportunity significantly facilitate the pricing process for their goods and make a more accurate calculation of the “fair” price, which will not alienate the consumer. Two global approaches to segmentation of the consumer market have been considered, the use of which allows the manufacturer to assess the company’s competitiveness, assess the market size, and assess the customer’s commitment

Genetic determinants of the development and course of membranous nephropathy

Membranous nephropathy (MN) is one of the most common causes of nephrotic syndrome in adults and is classified as either primary (idiopatic) or secondary MN according to underlying etiology (the later result from some known disease such as systemic autoimmune diseases, infections, malignancies, drugs, etc). In recent years, phospholipase A2 receptor 1 (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A) were identified as two major podocytic antigens involved in the pathogenesis of idiopatic MN (IMN). And the discovery of circulating antibodies specific for these target antigens has transformed the diagnostic workup and significally improved management of IMN. However why do such antibodies develop is not conclusively established. The role of underlying genetic factors is discussed. The review presents the results of recent studies, that have shown significant associations of specific genetic factors (particularly human leucocyte antigen class II and PLA2R1 genes) with IMN

New interaction paradigm of ecological, social and economic structures of human activity

Realities of the XXI century demand searching and grounding measures on changing economic, political, and the main thing, ideological institutions that determine trends of evolution and managing vital human activity at national and over-national levels. Using synergetic approach, the authors made an attempt to synthesize conclusions and main theses of neo-institutionalism theory, onto-psychology, as well as results of biological evolution for determining the way to overcome global ecological crisis at nano-level and to form a model of the mankind's optimal evolution on the base of principle "priorities through parities", using DNAsymbol as a code of survival, through co-evolution of economy and ecology. The main problem, existing even in economically developed countries, is the realization of the fact that the paradigm of the stationary economy is the only condition for the mankind's survival. To solve this problem serious transformation of ideological institutions is necessary, at the expense of comprehensive and based on onto-psychological methods program of ecological literacy, that should harmonically blend with the presented by the authors triads of state strategic management and achieving the goal of development. It is the transformation of the national matrix, content and direction of which are set in order to ensure a balance of interests of all participants in ecological and economic development, will lay the necessary rules, both formal and informal, in the style of human behavior, social groups, the national economy. Realization of the program ecological literacy within the national policy on ecological development of the regions is one of the most important conditions for a natural, not imposed from the outside, prepare to use the paradigm of a sustainable economy as the basis of economic, political and ideological institutions of modern society, which is primarily the formation of a new paradigm of human device - devices nano-level decision-making, consumer behavior

Neurogenic dysfunction of the lower urinary tract in infectious and inflammatory diseases of the spine: is there a correlation with clinical and radiological variants of myelopathy? Preliminary result of the analysis of a single-center cohort

Objective. To study the relationship between clinical and radiation variants of myelopathy and types of the neurogenic dysfunction of the lower urinary tract in patients with infectious spondylitis. Material and Methods. A single-center cohort observational study was conducted with the analysis of medical records and a prospective examination of 20 patients with infectious spondylitis complicated by neurogenic dysfunction of the lower urinary tract. Results. Infectious spondylitis can be complicated by the development of various urodynamic disorders, including neurogenic detrusor hyperactivity (30 %), its combination with detrusor-sphincter dissinergia (30 %) and a decrease in detrusor contractility (40 %). In 50 % of patients, an urodynamic examination revealed an increase in detrusor pressure of more than 40 cm water. There was no connection between the development of any type of lower urinary tract dysfunction and MRI types of myelopathy according to Vendatam, as well as between the level of spinal cord compression and the severity of neurological disorders according to AIS. Conclusion. The results of the study do not confirm the existence of a relationship between the various characteristics of myelopathy in infectious spondylitis and the results of urodynamic examination. The limitation of the reliability of the results is the small number of observations. Studies with a larger sample are required to assess the relationship between the clinical and radiation characteristics of myelopathy and variants of neurogenic dysfunction of the lower urinary tract in patients with infectious spondylitis

Тенденции в эндопротезировании крупных суставов у пациентов с ревматическими заболеваниями: опыт специализированного травматолого-ортопедического отделения

Total knee and hip arthroplasty (TKA and THA respectively) is frequently used in severe structural changes in patients with osteoarthritis (OA) and rheumatoid arthritis (RA).Objective: to evaluate the dynamics of the number of TKA of THA in patients with OA and RA treated in the Department of Traumatology and Orthopedics of V.A. Nasonova Research Institute of Rheumatology.Material and methods. The analysis of 11-year period (from 2012 to 2022) of surgical activity of the Department of Traumatology and Orthopedics of V.A. Nasonova Research Institute of Rheumatology.Results and discussion. Within the mentioned period, 2955 TKA and THA were performed in 1590 patients with OA and 1365 with RA. From 2012 to 2018, the number of surgeries in patients with OA and RA was approximately the same, but since 2019 there has been a significant increase in the number of total arthroplasties (TA) in OA. The median delta (Δ) of the number of TKA and THA performed annually over 11 years was 13.5 [-17.5; 75.7] in patients with OA and 2.5 [-10.25; 25.0] in patients with RA (p=0.032).Conclusion. In the last 11 years there was no significant dynamics in the number of TKA and THA in patients with RA. At the same time, there is a statistically significant increase in the number of TA in patients with OA, which is in line with the global trend.Тотальное эндопротезирование (ТЭ) коленного сустава (КС) и тазобедренного (ТБС) суставов широко используется при их тяжелых структурных изменениях у больных остеоартритом (ОА) и ревматоидным артритом (РА).Цель исследования – оценить динамику числа ТЭ КС и ТБС у пациентов с ОА и РА, находившихся на стационарном лечении в травматолого-ортопедическом отделении ФГБНУ «Научно-исследовательский институт ревматологии им. В.А. Насоновой» (НИИР им. В.А. Насоновой).Материал и методы. Проведен анализ хирургической активности травматолого-ортопедического отделения НИИР им. В.А.

Physiological Properties of Cholinergic and Non-Cholinergic Magnocellular Neurons in Acute Slices from Adult Mouse Nucleus Basalis

The basal forebrain is a series of nuclei that provides cholinergic input to much of the forebrain. The most posterior of these nuclei, nucleus basalis, provides cholinergic drive to neocortex and is involved in arousal and attention. The physiological properties of neurons in anterior basal forebrain nuclei, including medial septum, the diagonal band of Broca and substantia innominata, have been described previously. In contrast the physiological properties of neurons in nucleus basalis, the most posterior nucleus of the basal forebrain, are unknown.Here we investigate the physiological properties of neurons in adult mouse nucleus basalis. We obtained cell-attached and whole-cell recordings from magnocellular neurons in slices from P42-54 mice and compared cholinergic and non-cholinergic neurons, distinguished retrospectively by anti-choline acetyltransferase immunocytochemistry. The majority (70-80%) of cholinergic and non-cholinergic neurons were silent at rest. Spontaneously active cholinergic and non-cholinergic neurons exhibited irregular spiking at 3 Hz and at 0.3 to 13.4 Hz, respectively. Cholinergic neurons had smaller, broader action potentials than non-cholinergic neurons (amplitudes 64+/-3.4 and 75+/-2 mV; half widths 0.52+/-0.04 and 0.33+/-0.02 ms). Cholinergic neurons displayed a more pronounced slow after-hyperpolarization than non-cholinergic neurons (13.3+/-2.2 and 3.6+/-0.5 mV) and were unable to spike at high frequencies during tonic current injection (maximum frequencies of approximately 20 Hz and >120 Hz).Our results indicate that neurons in nucleus basalis share similar physiological properties with neurons in anterior regions of the basal forebrain. Furthermore, cholinergic and non-cholinergic neurons in nucleus basalis can be distinguished by their responses to injected current. To our knowledge, this is the first description of the physiological properties of cholinergic and non-cholinergic neurons in the posterior aspects of the basal forebrain complex and the first study of basal forebrain neurons from the mouse

КОКЛЮШ У ДЕТЕЙ – КЛИНИКО-ЭПИДЕМИЧЕСКАЯ ХАРАКТЕРИСТИКА В САМАРСКОЙ ОБЛАСТИ

Objective: to study the features of the clinical and epidemiological characteristics of whooping cough in children in the Samara region.Materials and methods: 389 cases of pertussis in the Samara region for 2015–2016 were analyzed.Results: it is shown that in spite of 95–98% vaccination coverage, in recent years there has been an increase in the incidence of whooping cough. Seasonality of morbidity remains. Among the children observed, the youngest children were not vaccinated against pertussis. The clinical picture of the disease remains typical with the classic course of catarrhal and spasmodic periods. Moderately severe forms of the disease predominate. Complications were noted mainly in unvaccinated children of the first year of life. The most frequent complications were pneumonia and apnea. There is a hypodiagnosis of pertussis in outpatient conditions. Infection often occurs under the mask of ARVI, while the sensitivity of the bacteriological method of diagnosis is zero. Of the methods for confirming the diagnosis, the most reliable is ELISA and PCR.Conclusion: these epidemiological and clinical features of pertussis current testify to the need to further improve methods of early diagnosis, especially express methods, etiopathagenetic treatment, specific prevention, antiepidemic measures in the foci of infection.Цель: изучить особенности клинико-эпидемической характеристики коклюша у детей в Самарской области.Материалы и методы: проанализированы 389 случаев коклюша в Самарской области за 2015–2016 гг.Результаты: показано, что, несмотря на 95–98% охват прививками, в течение последних лет наблюдается подъем заболеваемости коклюшем. Сохраняется сезонность. Среди наблюдавшихся детей преобладали дети младшего возраста, не привитые от коклюша. Клиническая картина заболевания остается типичной с классическим течением катарального и спазматического периодов. Преобладают среднетяжелые формы заболевания. Осложнения отмечались в основном у непривитых детей первого года жизни. Наиболее частыми осложнениями являлись пневмонии и апноэ. Имеет место гиподиагностика коклюша в амбулаторных условиях. Инфекция нередко протекает под маской ОРВИ, при этом чувствительность бактериологического метода диагностики равна нулю. Из методов подтверждения диагноза наиболее достоверным является ИФА и ПЦР.Заключение: указанные эпидемиологические и клинические особенности течения коклюша свидетельствуют о необходимости дальнейшего совершенствования методов ранней диагностики, особенно экспресс-методов, этиопатагенетического лечения, специфической профилактики, противоэпидемических мероприятий в очагах инфекции.

Новая коронавирусная инфекция (COVID-19) у больных туберкулёзом в Санкт-Петербурге

The aim of this work was to attempt to analyze the demographic structure, clinical and radiological forms of tuberculosis and COVID-19, as well as the course and outcome of the disease in patients with this coinfection in the light of a new and still poorly understood problem of the mutual influence of tuberculosis and COVID-19.Material and methods. Examination and treatment were carried out in the infectious-tuberculosis departments of the Botkin Clinical Infectious Disease Hospital. We examined 63 patients identified in the first seven months of the epidemic in the multimillion city of St. Petersburg (Russia). Tuberculosis, confirmed by conventional bacteriological and molecular genetic methods, had an active phase in all of them. The new coronavirus infection was verified by a positive polymerase chain reaction test for SARS-CoV-2.Results. Tuberculosis in 43 patients was detected simultaneously with COVID-19, in 20 people it preceded coronavirus infection. Disseminated forms of tuberculosis prevailed - 50.8%; in 36.5%, two or more organs and systems were affected, which is associated with a high proportion (54.0%) of HIV-positive patients with an advanced stage of the disease. Lung damage with COVID-19 was noted in 36.5%. Fatal outcomes ended in 20.6% of cases of coinfection, the structure of the causes of death is given.Conclusion. An assumption was made about the possibility of an aggravating effect of tuberculosis on COVID-19 in the case of severe or widespread forms of these diseases. The negative influence of HIV infection on the outcome of the disease has also been shown. Further follow-up is required to identify more reliable associations between tuberculosis and COVID-19. Цель: попытка выполнить анализ демографической структуры, клинико-рентгенологических форм туберкулёза и COVID-19, а также течения и исхода заболевания у пациентов с указанной коинфекцией в свете новой и пока малоизученной проблемы взаимного влияния туберкулёза и COVID-19.Материалы и методы. Обследование и лечение проводилось в инфекционно-туберкулёзных отделениях Клинической инфекционной больницы им. С.П. Боткина. Обследованы 63 пациента, выявленные в первые 7 месяцев эпидемии в многомиллионном городе Санкт-Петербурге (Россия). Туберкулёз, подтверждённый общепринятыми бактериологическими и молекулярно-генетическими методами, у всех имел активную фазу течения. Новая коронавирусная инфекция верифицирована положительным тестом полимеразно-цепной реакции на SARS-CoV-2.Результаты. Туберкулёз у 43 больных был обнаружен одновременно с COVID-19, у 20 человек он предшествовал коронавирусной инфекции. Преобладали диссеминированные формы туберкулёза – 50,8%; в 36,5% имело место поражение двух и более органов и систем, что связано с высокой долей (54,0 %) ВИЧ-положительных пациентов с продвинутой стадией заболевания. Поражение лёгких при COVID-19 отмечено в 36,5%. Летальным исходом завершились 20,6% случаев коинфекции, приведена структура причин смерти.Заключение. Сделано предположение о возможности отягощающего влияния туберкулёза на COVID-19 в случае тяжёлых или распространённых форм этих заболеваний. Показано также отрицательное влияние ВИЧинфекции на исход заболевания. Требуются дальнейшие наблюдения для выявления более более достоверных взаимосвязей туберкулёза и COVID-19.
