Aim.To describe the characteristics of patients who were invited in observational, prospective study on a value-based approach to assess the outcomes of treatment of patients with stable coronary artery disease (CAD) by percutaneous coronary intervention (PCI).Material and methods.We analyzed the baseline characteristics of patients with stable CAD enrolled in a planned PCI with stenting at Almazov National Medical Research Center in 2017. Statistical processing of the results was carried out using Statistica 6.0 (Statsoft Russia) and Microsoft Excel 2017. All registered patients were included in the statistical analysis. Based on the initial clinical characteristics of the patients included in the study, descriptive statistical parameters were calculated. For continuous variables, the mean value and standard deviation were calculated, for the categorical variables — the frequency of characteristic occurrence.Results. From January 1, 2017 to December 31, 2017, were performed 1740 PCI operations with stenting in 1458 patients aged 63,8±9,6 years (men — 1008 (69,1%)). At the time of admission to the hospital, the body mass index was 29,4±5,2 kg/m2, BP=132,3±15,1/79,6±8,5 mm Hg; HR=69,4±8,3 beats per minute. PCI of one coronary artery was performed in 75,6%, multivascular — in 16,6%, in chronic occlusions — in 4,6% and in bifurcation lesions — in 3,2% of patients, respectively. Type 4a myocardial infarction as a complication of PCI was registered in 2,9% of patients. The average duration of inpatient treatment was 5,5±3,4 days.Conclusion.Patients with stable CAD who underwent PCI are a representative sample which allows the assessment of treatment outcomes, an objective assessment of the intervention and the calculation of pharmacoeconomic parameters. An observational study will help identifying the factors affecting the efficiency of surgery and getting knowledge of patients’ opinions about this method.

Electrocardiography (ECG) takes the lead in assessing the prevalence of coronary artery disease (CAD) in the population. ECG disorders, grouped in the Major (certain) and Minor (possible) categories, are prognostic markers of a high risk of cardiovascular diseases and sudden cardiac death. Unified assessing methods of ECG disorders prevalence and their associations with socio-demographic parameters have not previously been made in Russia.Aim. To study the prevalence of ECG parameters of certain and possible coronary artery disease among population of Russia, depending on the socio-demographic characteristics — age, sex, education and place of residence (city or country).Material and methods. We used 17504 ECGs from representative samples of population (25-64 years old), who participated in the epidemiological study “Epidemiology of cardiovascular diseases and their risk factors in the Russian Federation”. The analysis using Minnesota code was carried out among men and women of four age groups, two educational levels, among citizens and countrymen.Results. The highest prevalence was observed in the “Certain” (5,7%) and “Possible signs of CAD” (7,1%) categories, in the “Certain” (3,8%) and “Possible myocardial ischemia” groups (4,9%), the smallest is in the “Rhythm and conduction disorder” (0,7%) and “STT changes in left ventricular hypertrophy” (0,4%) groups. It was shown that the frequency of ECG disorders increases with age, has an sharp increase after 55 years, regardless of sex. In the age dynamics of categories, STT changes and atrial fibrillation have a decrease of gender differences. All groups of ECG disorders are detected more often among men than women, except for STT changes. With an increase in the level of education, the frequency of ECG pathologies decreases, with the exception of the groups of “major” and “minor Q (QS)”, “major rhythm and conduction disorders”. The prevalence of most ECG disorders does not depend on the place of residence. However, signs of major myocardial ischemia in men are more common in country than in the city (3,9% vs. 2,7%, p<0,05).Conclusion. The results confirm the patterns identified earlier. There is a steady association of ECG data with socio-demographic characteristics.

Aim. To identify and assess the significance of clinical and functional data characterizing cardiac remodeling, as well as inflammatory and fibrosis markers in patients with various clinical forms that promote the progression of atrial fibrillation (AF).Material and methods. We observed 213 patients with arterial hypertension or in combination with coronary artery disease, who were diagnosed with AF. For the clinical and functional assessment of various clinical forms of AF, the significance of certain clinical, hemodynamic, structural, functional, and immunological risk factors for AF was studied. We used the method of binary logistic regression and calculated the significance of the risk factors odds ratio (OR).Results. We made a database consisting of 33 indicators characterizing the clinical, hemodynamic and structural-functional heart condition, inflammatory and fibrosis markers, the significance of which was ambiguous in various clinical groups of AF patients. We identified enough informativeness of the OR significance for indicators of atrial electrical remodeling, which significantly increases from the paroxysmal AF to the persistent form. It confirms a significant role for the heterogeneity of pulses in the atria during the progression of AF. The degree of structural remodeling of both the atria and ventricles also significantly increases with the progression of AF. We also noted that inflammatory markers have statistically significant role with paroxysmal AF. With persistent AF, the significance of OR for inflammatory markers increases, and with permanent AF, their significance decreases. The significance of the OR in fibrosis marker is significantly high with AF and in the further AF progression, and it significantly increases with the persistent AF form.Conclusion. We determined different degrees of electrical and structural remodeling of the atria and ventricles in patients with various clinical forms of AF. At the same time, there is an increase in the reliability of OR in inflammatory and fibrosis markers. However, in patients with persistent AF, the duration of AF and increase in the significance of the OR in fibrosis marker come to the fore.

Published: December 2018

Aim. To compare the known methods of blood pressure (BP) measurement in the morning and a new method for estimating the average morning BP for fixed time intervals, comparing their reproducibility and validity.Material and methods. We analyzed database containing 983 cases of ambulatory blood pressure monitoring (ABPM). Results of ABMP in patients with hypertension without severe associated diseases and weekly cancellation of antihypertensive therapy were analyzed. Blood pressure data per 24-hour period, day and night, level and rate of morning BP surge were assessed. In addition, we proposed new method for estimating the average morning BP level for fixed time intervals, based on calculating the average BP level for the following time windows: from 5:00 to 7:00 a.m., from 7:00 to 9:00 a.m., from 9:00 to 11:00 a.m. To assess the reproducibility of the new method, we determined correlations between the first and second group results calculated by the new method based on two repeated ABPM conducted with 1-2 weeks interval (n=90). To study the validity of the new method for measurement of average morning BP level, we used an objective validation criterion — Left Ventricular Myocardium Mass Index (LVMMI). There were performed 98 echocardiographic tests with the use of Acuson 128XP. LVMMI was calculated using the L. Teichholtz method (1976).Results. The new method for measurement of average morning BP level had good reproducibility while the reproducibility of dynamic showings of ABMP (level and rate of morning BP surge) was low. A new method for assessing morning blood pressure was characterized by a high level of validity: the indicators obtained using this technique reliably correlated with the validation criteria: LVMI and the average daily blood pressure level.Conclusion. The proposed new method for estimating the average morning level of blood pressure has a high level of validity and reproducibility. Time interval from 7 to 9 a. m. seems to be the most optimal. The maximum reproducibility of the showings was noted during this period.

En un contexto de expansión del capital hacia la Cordillera de Los Andes, el decreto nacional 225/17 dispuso la venta de inmuebles considerados ociosos o desaprovechados. Entre ellos, un terreno que desde 1901 ha sido administrado por el Ejército Nacional, denominado Campo Los Andes. Este se sitúa en el Valle de Uco (centro-oeste argentino), epicentro del desarrollo turístico-vitivinícola de vinos de alta gama. Para enfrentar la venta, sus moradores civiles junto a muy diversos actores sociales –entre ellos, integrantes de asambleas ciudadanas, partidos políticos, organizaciones campesinas y ambientalistas y distintos profesionales– llevaron a cabo una serie de acciones colectivas en defensa de dicho territorio y sus diversas materialidades ambientales e históricas. Por medio de observaciones en foros y cortes de ruta, de la consulta de notas periodísticas y documentos legales, describimos la diversidad de actores sociales que se articularon a lo largo de los meses posteriores a la publicación del decreto. Asimismo, analizamos cómo en este proceso la socialización de experiencias y del conocimiento socio-ambiental y cultural sobre Campo Los Andes propició la reconstrucción de una memoria social colectiva, la cual contrarrestó las propuestas hegemónicas de desarrollo orientadas al mercado financiero y al extractivismo, en este caso, el vitivinícola y el turismo de elite.
Abstract
In a context of capital expansion towards the Andes Mountains, the decree 225/17 ordered the sale of properties considered idle or unused. Among them was a land that since 1901 has been administered by the National Army, called Campo Los Andes. It is located in the Valle de Uco (Central-West Argentina), epicenter of the tourism-winegrowing development of high range wines. To stop this sale, its civil dwellers together with very diverse social actors –among them, members of citizen assemblies, political parties, peasant and environmental organizations and different professionals– carried out collective actions in defense of this territory and of the national sovereignty. Through observations in forums and road cuts, gathering of journalistic notes and legal documents, we describe the diversity of social actors that were articulated during the months following the publication of the decree. Likewise, we analyze how in this process, the socialization of experiences and socio-environmental and cultural knowledge about Campo Los Andes led to the reconstruction of a collective social memory, which counteracted the hegemonic proposals of development oriented to the financial market and extractivism, in this case, viticulture and elite tourism.
El territorio como campo de transformaciones socio-productivas. La posición de los agentes/ The territory as a field of socio-productive transformations. The position of agents

Published: December 2018

La expansión del capitalismo, a fines del siglo pasado, ha provocado profundas transformaciones en las estructuras sociales y en las relaciones de producción en el agro. En el norte de Córdoba, Argentina, lugar donde se realizó este estudio de caso, la ampliación de la frontera agraria con centralidad en la soja propició la inclusión de nuevos agentes productivos y la exclusión de otros. Así, coexistían diferentes formas de ocupación y modalidades de apropiación y puesta en producción de la tierra. Asimismo, la selección de lugares aptos para que el capital desplegara sus estrategias de reproducción generó la fragmentación del espacio geográfico. Este artículo se propone identificar a los productores que configuran la estructura social agraria y comprender cómo estos agentes –definidos por el volumen y la estructura de capital que poseen– generan el campo productivo y las relaciones de fuerza que lo caracterizan. La estrategia metodológica combina el análisis de datos secundarios y primarios provenientes de entrevistas en profundidad realizadas a productores, referentes técnicos y agentes institucionales de la región.
Abstract
The expansion of capitalism at the end of the last century has led to profound changes in social structures and in the relations of production in agriculture. In the north of Córdoba, Argentina, where this case study was carried out, the expansion of the agricultural frontier with centrality in soy allowed the inclusion of new productive agents and the exclusion of others. Thus, different forms of occupation and modalities of appropriation and putting into production of the land coexisted. Likewise, the selection of suitable places for capital to display its reproduction strategies generated the fragmentation of the geographical space. This article aims to identify the producers that shape the agrarian social structure, and understand how these agents, defined by the volume and structure of capital they possess, generate the productive field and the relations of force that characterize it. The methodological strategy combines the analysis of secondary and primary data from in-depth interviews with producers, technical referents and institutional agents in the region.

El modelo del agronegocio en América Latina, marcado por el imperativo de flexibilidad, el desarrollo tecnológico y la producción en red ha supuesto profundas transformaciones en el empleo y en las pautas de movilidad territorial de capitales y trabajadores agrarios. Pese a su escasa visibilidad en los estudios recientes, los asalariados transitorios migrantes son un grupo complejo y heterogéneo, presente en una amplia variedad de mercados de trabajo. El objetivo de este artículo es reflexionar sobre la espacialidad de estos trabajadores, desde una perspectiva crítica. Se revisan los estudios sobre los trabajadores transitorios migrantes en América Latina (focalizando en Argentina, México y Brasil), con el fin de examinar el modo en que ha sido abordada la dimensión espacial, tomando como referencia el paso de las miradas estructuralistas sobre la movilidad a las post-estructuralistas. Se presenta un estudio de caso en el la región pampeana argentina, sobre asalariados especializados en nuevas tecnologías. Se desarrolla una propuesta teórico-conceptual y metodológica con eje en el concepto de “arreglo espacio-temporal”, el cual permite abordar de forma integrada y dialéctica los distintos sentidos de la espacialidad, la dimensión espacial y la temporal y las estrategias de los trabajadores en relación con las del capital.
Abstract
The model of agribusiness in Latin America, marked by the imperative of flexibility, technological development and network production, has led to profound changes in employment and in the patterns of spatial mobility of capital and agrarian workers. Despite their limited visibility in recent studies, migrant temporary agrarian workers are a complex and heterogeneous group, present in a wide variety of labor markets. The aim of this article is to reflect on the spatiality of these workers, from a critical perspective. We review studies referred to migrant temporary workers in Latin America (focusing on Argentina, Mexico and Brazil), in order to examine the way in which the spatial dimension has been approached, taking as reference the passage from structuralist perspectives on mobility to post-structuralist. We present a case study in the Pampas region (Argentina) about workers specialized in new technologies. We offer a theoretical-conceptual and methodological proposal with axis in the concept of “spatio-temporal fix”, which allows to approach in an integrated and dialectical way the different senses of spatiality, the spatial and temporal dimension and the strategies of workers in relation to those of capital.

<p>В статье молодежный аспект массовой культуры выводится из представления о ней как закономерного этапа общественного развития. В силу этого ее неверно связывать только с характеристиками индустриального общества. В современном обществе (информационном, сетевом, цифровом и т. д.) изменения в массовой культуре хорошо видны при выделении ее молодежного аспекта: естественные свойства молодежи в условиях широкого распространения новых коммуникативных технологий во многом определяют специфику массовой культуры начала XXI в., поскольку молодежь выступает одним из наиболее активных ее носителей.</p>

ABSTRACT – This study associated data of performance, gas exchange and morphometric analysis of the root system using the WinRhizo software. The main objective was to verify how the modifications in the root system contribute to maintain the photosynthetic rates and productivity in sorghum hybrids divergent regarding tolerance to water deficit. The 1G 282 tolerant hybrid presented higher tolerance to desiccation of the leaves, higher grain productivity (68.33%) and maintained its photosynthetic rate 2.13 times higher compared to the sensitive BRS 332 during the water deficit. Both hybrids presented responses related to desiccation prevention, characterized by modifications of the root system that are capable to benefit absorption of water and nutrients under stress. Besides, 1G 282 showed more developed and responsive root system, especially due to a higher superficial area of very fine roots (42.67%), volume of fine roots (36.90%) and very fine roots (53.18%) under water deficit when compared to the sensitive BRS 332 at the same conditions.Keywords: Sorghum bicolor, roots, WinRhizo, photosynthesis. MODIFICAÇÕES DO SISTEMA RADICULAR, TROCAS GASOSAS E PRODUTIVIDADE EM HÍBRIDOS DE SORGO CULTIVADOS SOB DÉFICIT HÍDRICO RESUMO – O estudo em questão associou dados de rendimento, trocas gasosas e morfometria do sistema radicular utilizando o software WinRhizo. O principal objetivo foi verificar como modificações do sistema radicular contribuem para a manutenção da taxa fotossintética e produtividade em híbridos de sorgo divergentes para tolerância ao déficit hídrico (WD), sendo um tolerante (1G 282) e outro sensível (BRS 332). O híbrido tolerante 1G 282 apresentou maior tolerância à desidratação do tecido foliar, além de manter uma taxa fotossintética 2,13 vezes maior e maior rendimento de grãos (68,33%) em relação ao sensível BRS 332 durante o WD. Ambos os híbridos apresentaram respostas de prevenção à seca, caracterizada por modificações do sistema radicular capazes de favorecer a absorção de água na condição de estresse. No entanto,1G 282 demonstrou possuir um sistema radicular mais desenvolvido e responsivo, especialmente por exibir maior área superficial de raízes muito finas (42,67%) e volume de raízes finas (36,90%) e muito finas (53,18%) em condição de WD, quando comparado com o sensível BRS 332 nas mesmas condições de cultivo.Palavras-chave: Sorghum bicolor, raízes, WinRhizo, fotossíntese.

RESUMO – O cultivo do sorgo granífero avança no Brasil. Todavia, existem evidências sugerindo efeito inibitório sobre a soja cultivada em sucessão. Objetivou-se investigar o efeito inibitório do cultivo de sorgo granífero (BRS 332) sobre o desempenho da soja (Glycine max (L.) Merrill) semeada em sucessão. Para isso, realizou-se um experimento de campo em blocos ao acaso em esquema de parcela subdivididas. As parcelas foram compostas pelas culturas antecessoras sorgo e milho e as subparcelas, por cinco datas de semeadura da soja após a colheita das culturas antecessoras (0, 20, 40, 60 e 80 dias após a colheita). Observou-se que o sorgo, como cultura antecessora, resultou em menores percentagens de emergência, índice de velocidade de emergência, altura de inserção de primeira vagem e número de vagens por planta de soja, apesar da produtividade de grãos não ter sido afetada. Conclui-se que o desenvolvimento vegetativo inicial da soja é afetado negativamente quando a semeadura é realizada em até 40 dias após a colheita do sorgo. Contudo, o cultivo anterior de sorgo na mesma área, comparativamente ao cultivo anterior do milho, não é capaz de afetar a produtividade da soja.Palavras-chave: Glicine max, Sorghum bicolor, sorgoleone, Zea mays. INHIBITORY EFFECT OF SORGHUM ON SOYBEAN IN SUCCESSION ABSTRACT - The cultivation of grain sorghum is advancing in Brazil, however, there is evidence suggesting an inhibitory effect on soybeans grown in succession. The objective of this study was to investigate the inhibitory effect of grain sorghum (BRS 332) on the performance of soybeans (Glycine max (L.) Merrill) seeded in succession. For this, a field experiment was carried out in a randomized blocks design in a subdivided plot scheme. The plots were composed of the predecessor crops sorghum and maize and the subplots were five soybean sowing dates after harvesting the predecessor crops (0, 20, 40, 60 and 80 days after harvest). It was observed that sorghum as a predecessor crop resulted in lower emergence percentages, emergence speed index, first pod insertion height and number of pods per soybean plant, although grain yield was not affected. As conclusion, the initial vegetative development of soybean was negatively affected when sowing was carried out up to 40 days after sorghum harvest. However the previous cultivation of sorghum in the same area did not affect soybean productivity, compared to the previous corn crop.Keywords: Glicine max, Sorghum bicolor, sorgoleone, Zea mays.
