RESUMEN Introducción: el lupus eritematoso sistémico (LES) se conoce como una enfermedad autoinmune multisistémica, cuya causa es desconocida, se caracteriza por la presencia de complejos inmunes y autoanticuerpos. En series internacionales se describe una presentación de procesos infecciosos en estos pacientes hasta en un 75 % de los casos, las infecciones ocurren tanto al inicio de la enfermedad como en etapas tardías, y son causa directa de muerte en 30 % a 60 % de los casos y motivo de hospitalización hasta de 30 %. Objetivos: determinar los procesos infecciosos más frecuentes en pacientes con lupus eritematoso sistémico internados en el Servicio de Clínica Médica del Hospital Nacional en el periodo 2022-2023. Metodología: diseño observacional, descriptivo de corte transversal de pacientes con diagnóstico de lupus eritematoso sistémico según criterios de European League Against Rheumatism (EULAR)-2019 que se encuentran internados en el servicio de Clínica Médica del Hospital Nacional (Itaugua-Paraguay) en el periodo de 2022-2023. Resultados: la edad media de los pacientes fue de 34 años, con predominio del sexo femenino en el 88.18 %. Las infecciones del aparato respiratorio fue la más frecuentemente diagnosticada en 50 (45.45 %) pacientes, seguido por la infección de vías urinarias 47 (42.38 %) pacientes, el condicionante de riesgo predominante fue el uso de corticoides en un total 105 (96.40 %) pacientes, se estableció en un total de 97 (88.18 %) pacientes con antibioticoterapia, dentro del aspecto demográfico de la zona urbana 56 (50.90 %) pacientes y rural 54(49.1 %). Conclusión: la infección del aparato respiratorio fue la infección más frecuente, el condicionante de riesgo predominante es el uso de corticoides y recibieron antibioticoterapia la cual en monoterapia fue la más utilizada

ABSTRACT Introduction: systemic lupus erythematosus (SLE) is known as a multisystem autoimmune disease, whose cause is unknown, and is characterized by the presence of immune complexes and autoantibodies. In international series, presentation of infectious processes is described in these patients in up to 75 % of cases. Infections occur both at the beginning of the disease and in late stages, and are a direct cause of death in 30 % to 60 % of patients. Cases and reason for hospitalization up to 30 %. Objectives: determine the most frequent infectious processes in patients with systemic lupus erythematosus admitted to the Medical Clinic Service of the Hospital Nacional in the period 2022-2023. Methodology: observational, descriptive cross-sectional design of patients with a diagnosis of systemic lupus erythematosus according to criteria of European League Against Rheumatism (EULAR)-2019 who are admitted to the Medical Clinic service of the Hospital Nacional (Itauguá-Paraguay) in the period of 2022-2023. Results: the average age of the patients was 34 years, with a predominance of the female sex in 88.18 %. Respiratory system infections were the most frequently diagnosed in 50 (45.45 %) patients, followed by urinary tract infection in 47 (42.38 %) patients. The predominant risk factor was the use of corticosteroids in a total of 105 (96.40 %) patients, it was established in a total of 97 (88.18 %) patients with antibiotic therapy, within the demographic aspect of the urban area 56 (50.90 %) patients and rural 54 (49.1 %). Conclusion: respiratory tract infection was the most frequent infection, the predominant risk factor is the use of corticosteroids and they received antibiotic therapy, which in monotherapy was the most used.

RESUMEN Introducción: la diabetes mellitus es una enfermedad crónica que, al no ser controlada, puede desencadenar en complicaciones macro y microvasculares. Uno de los indicadores de un adecuado control glucémico es la hemoglobina glicosilada. Objetivos: determinar la frecuencia de complicaciones macro y microvasculares en pacientes diabéticos tipo 2 con hemoglobina glicosilada alterada internados en el Hospital Nacional de Itauguá periodo 2022 - 2023 Metodología: estudio observacional, descriptivo de corte transversal que incluyó a 170 pacientes adultos internados en el servicio de clínica médica del Hospital Nacional (Itauguá, Paraguay) durante los años 2022 y 2023. Resultados: la edad media fue de 58 ± 12 años, con predominio del sexo femenino (51 %). La complicación más frecuentemente diagnosticada fue la enfermedad del pie relacionada a la diabetes con 83 pacientes (49 %), seguido por retinopatía diabética 23 (14 %). El valor promedio de hemoglobina glicosilada fue de 10 ± 2 %. Solamente 6 (4 %) del total de pacientes presentó un valor de HbA1C≥ 7,1 %. La comorbilidad asociada más frecuente fue la hipertensión arterial 87 (51 %). El 91 % de los pacientes conocía ser portador de la enfermedad, el 80 % recibía algún tipo de tratamiento. Conclusiones: el pie diabético fue la complicación vascular diagnosticada con mayor ,frecuencia, especialmente en pacientes con HbA1C≥ 7,1 %.

ABSTRACT Introduction: diabetes mellitus is a chronic disease that, if not controlled, can lead to macro- and microvascular complications. One of the indicators of adequate glycemic control is glycosylated hemoglobin. Objectives: to determine the frequency of macro and microvascular complications in type 2 diabetic patients with altered glycosylated hemoglobin admitted to the Hospital Nacional from 2022 to 2023 Methodology: this was an observational, descriptive, cross-sectional study that included 170 adult patients admitted to the Internal Medicine service of the Hospital Nacional (Itauguá, Paraguay) during the years 2022 and 2023. Results: the mean age was 58 ± 12 years, with a predominance of the female sex (51 %). The most frequently diagnosed complication was foot disease related to diabetes with 83 patients (49 %), followed by diabetic retinopathy 23 (14 %). The average value of glycosylated hemoglobin was 10 ± 2 %. Only 6 (4 %) of the total patients had an HbA1C value ≤7 %. The most frequent associated comorbidity was arterial hypertension 87 (51 %). 91 % of the patients knew they were carriers of the disease, 80 % received some type of treatment. Conclusions: diabetic foot was the most frequently diagnosed vascular complication, especially in patients with HbA1C ≥7.1 %.

Abstract In Brazil, 65% of the electric power production comes from hydroelectric power plants (HPPs). In some cases, these power plants divert the course of rivers, resulting in regions impacted by the absence of water, which are known as reduced fow sections (RFS). These sections are regulated by legislation and aim to maintain the minimum fow necessary to preserve the fauna, flora, fish, and human consumption in the region. Depending on the time of year, this minimum flow, also known as ecological flow (residual flow), can reach significant values, resulting in the interruption of power generation in these HPPs. This article presents a study case of two hydroelectric power plants located in different Brazilian states. The objective of this study is to explore the feasibility of implementing auxiliary generator groups that can operate uninterruptedly at different drop heights while ensuring the preservation of residual flow during low flow periods or taking advantage of the overflow flow by spillways during high flow periods. This auxiliary system would use the same set of structures and transmission systems as the main power plant, minimizing environmental impacts and implementation costs, allowing this solution to be implemented in HPPs that face this type of problem in Brazil. The results obtained indicate that HPPs with larger reservoirs have a greater ability to maintain residual flows with minimal generation loss and that run-of-the-river power plants are the most impacted by the maintenance of residual flow.

Abstract Background: Currently, there is no uniform and official terminology in Portuguese for reflectance confocal microscopy analysis, despite the increasing number of Brazilian dermatologists using this new tool. Objective: To present the terminology in Brazilian Portuguese for the description of reflectance confocal microscopy and establish the first Brazilian consensus on terms related to normal skin and cutaneous tumors. Methods: 10 Brazilian specialists from different institutions and states of Brazil were selected to evaluate the best corresponding terms in Portuguese for normal skin, melanocytic and non-melanocytic tumors. The terms used were translated from international consensuses in the English language. The modified Delphi method was used to create the consensus in 3 steps. Results: The terms considered the most appropriate in the Portuguese language to describe the findings of normal skin, melanocytic and non-melanocytic lesions in the reflectance confocal microscopy analysis were presented. Study limitations: The limitations of the present study include the number of participants and limited regional representation (only two of the five Brazilian regions were represented). Conclusion: This Brazilian consensus represents an opportunity for dermatologists and physicians specializing in cutaneous oncology to become familiar with reflectance confocal microscopy, propagating the technique in clinical and research environments to stimulate national and international publications on this subject.

ABSTRACT Objective. To provide a comprehensive overview of geographical patterns (2001–2010) and time trends (1993–2012) of cancer incidence in children aged 0–19 years in Latin America and the Caribbean (LAC) and interpret the findings in the context of global patterns. Methods. Geographical variations in 2001–2010 and incidence trends over 1993–2012 in the population of LAC younger than 20 years were described using the database of the third volume of the International Incidence of Childhood Cancer study containing comparable data. Age-specific incidence per million person-years (ASR) was calculated for population subgroups and age-standardized (WSR) using the world standard population. Results. Overall, 36 744 unique cases were included in this study. In 2001–2010 the overall WSR in age 0–14 years was 132.6. The most frequent were leukemia (WSR 48.7), central nervous system neoplasms (WSR 23.0), and lymphoma (WSR 16.6). The overall ASR in age group 15–19 years was 152.3 with lymphoma ranking first (ASR 30.2). Incidence was higher in males than in females, and higher in South America than in Central America and the Caribbean. Compared with global data LAC incidence was lower overall, except for leukemia and lymphoma at age 0–14 years and the other and unspecified tumors at any age. Overall incidence at age 0–19 years increased by 1.0% per year (95% CI [0.6, 1.3]) over 1993–2012. The included registries covered 16% of population aged 0–14 years and 10% of population aged 15–19 years. Conclusions. The observed patterns provide a baseline to assess the status and evolution of childhood cancer occurrence in the region. Extended and sustained support of cancer registration is required to improve representativeness and timeliness of data for childhood cancer control in LAC.

RESUMO Objetivo. Apresentar uma visão abrangente dos padrões geográficos (2001 a 2010) e das tendências temporais (1993 a 2012) da incidência de câncer em crianças e jovens de 0 a 19 anos na América Latina e no Caribe (ALC) e interpretar os resultados no contexto de padrões mundiais. Métodos. Foram descritas variações geográficas de 2001 a 2010 e tendências de incidência de 1993 a 2012 na população com menos de 20 anos da ALC usando informações comparáveis da base de dados do terceiro volume do estudo International Incidence of Childhood Cancer. Foram calculadas taxas de incidência específica por idade por milhão de pessoas-ano (ASR, na sigla em inglês) para subgrupos populacionais e taxas padronizadas por idade usando a população padrão mundial (WSR, na sigla em inglês). Resultados. No total, foram incluídos 36 744 casos únicos. No período de 2001 a 2010, a WSR para todos os tumores combinados na faixa etária de 0 a 14 anos foi de 132,6. Os diagnósticos mais frequentes foram leucemia (WSR de 48,7), neoplasias do sistema nervoso central (WSR de 23,0) e linfoma (WSR de 16,6). A ASR para todos os tumores combinados na faixa etária de 15 a 19 anos foi de 152,3, e a maior taxa foi a de linfoma (ASR de 30,2). A incidência foi maior no sexo masculino do que no sexo feminino e maior na América do Sul do que na América Central e no Caribe. De modo geral, em comparação com as estimativas mundiais, a incidência na ALC foi menor, exceto para leucemia e linfoma entre 0 e 14 anos e para outros tumores e tumores não especificados em qualquer idade. A taxa de incidência na faixa etária de 0 a 19 anos aumentou em 1,0% ao ano (IC de 95% [0,6, 1,3]) entre 1993 e 2012. Os registros incluídos cobriam 16% da população de 0 a 14 anos e 10% da população de 15 a 19 anos. Conclusões. Os padrões observados servem de referência para avaliar o status e a evolução da ocorrência de câncer infantil na região. É necessário garantir um apoio ampliado e consistente aos registros de câncer para aprimorar a representatividade e a disponibilidade das informações em tempo adequado para o controle do câncer infantil na ALC.

ABSTRACT Objective: To compare cancer mortality among workers exposed to gamma and X radiation and the general population of the city of São Paulo, as well as that of the subgroup monitored with those not monitored for gamma and X radiation in a work unit with ionizing radiation based in the city of São Paulo. Methods: Between 2016 and 2021, a retrospective open cohort study was carried out with workers who were employed from 08/31/1956 to 12/31/2016 based on data collected at the company and in official institutions. Standardized mortality ratios (SMR) were calculated by sex, age and calendar period of cancers grouped according to type, risk factor and organ system in two analyses: in the external analysis, the mortality of the study population was compared with that of the general population of the city of São Paulo; In the internal analysis, the mortality of the monitored subgroup was compared with that of the subgroup not monitored for gamma and X radiation. Results: The external mortality analysis showed SMR=0.224 (95%CI 0.208–0.240) and the healthy worker effect, while the internal mortality analysis showed SMR=0.685 (95%CI 0.618–0.758). Conclusion: This study showed lower cancer mortality among exposed workers when compared to mortality in the general population and the healthy worker effect. Among workers monitored for gamma and X radiation, cancer mortality was lower when compared to those not monitored.

RESUMO Objetivo: Comparar a mortalidade por câncer entre trabalhadores expostos à radiação gama e X e a população geral do município de São Paulo, bem como a do subgrupo monitorado com o não monitorado para radiação gama e X em uma unidade de trabalho sediada no município de São Paulo. Métodos: Entre 2016 e 2021 foi realizado estudo de coorte aberta retrospectiva com trabalhadores que tiveram vínculo empregatício desde 31/08/1956 até 31/12/2016 a partir de dados coletados na empresa e em instituições oficiais. Foram calculadas as razões de mortalidade padronizadas (RMP) por sexo, idade e período calendário de cânceres agrupados segundo o tipo, o fator de risco e o sistema orgânico em duas análises: na análise externa, comparou-se a mortalidade da população de estudo com a da população geral do município de São Paulo; já na análise interna, comparou-se a mortalidade do subgrupo monitorado com a do subgrupo não monitorado para radiação gama e X. Resultados: A análise externa de mortalidade mostrou RMP=0,224 (IC95% 0,208–0,240) e o efeito do trabalhador sadio, enquanto a análise interna de mortalidade mostrou RMP = 0,685 (IC95% 0,618–0,758). Conclusão: Este estudo mostrou menor mortalidade por câncer entre os trabalhadores expostos quando comparada com a mortalidade da população geral e o efeito do trabalhador sadio. Entre os trabalhadores monitorados para radiação gama e X, a mortalidade por câncer foi menor quando comparada com a dos não monitorados.

SUMMARY OBJECTIVE: The growing availability of devices for mobile learning has created new opportunities for teaching. With the development of smartphone apps based on audience response systems, there is a possibility to quickly assess student knowledge. The education of health professionals, including medical students, is an essential strategy for tuberculosis control. In the context of the coronavirus disease 2019 pandemic, audience response systems are very useful as online assessment tools. The aim of this study was to use the audience response systems Socrative to assess medical students during a class on tuberculosis. METHODS: This is a quasi-experimental before-and-after study, with pre- and post-tests carried out through the Socrative app, respectively, before and after a lecture on tuberculosis for medical students. Also, a cross-sectional study was carried out after the course to evaluate the participant's satisfaction through an electronic, structured questionnaire with a Likert-type scale. RESULTS: A total of 126 students were included in the study. The overall mean pre- and post-test scores were 5.98±1.59 and 8.37±1.36, respectively, with a statistically significant difference (p<0.0001). Almost all students were totally satisfied with the use of Socrative on pre- and post-tests. CONCLUSION: This study describes how the use of Socrative in a tuberculosis class was well received by students. In addition, the baseline knowledge on tuberculosis was low in some topics, with some improvement after the lecture. These findings emphasize the need to further improve the students’ knowledge on tuberculosis and help instructors customize the lecture based on the gaps identified in the Socrative assessment.

ABSTRACT The physical and microbiological characteristics of the soil are indicators considered in the assessment of the conditions of anthropized areas and are tools to identify levels of degradation, define the best crops, and thus, propose actions that help the producer to choose the appropriate soil management. In this regard, the aim of this work was to analyze the physical and microbiological properties of the soil in different agricultural production systems and in a preserved area. The research was carried out at a property located in the municipality of Campo Novo do Parecis - MT, Cerrado`s Biome. For the physical analysis, samples at depths of 0-0.10 m, 0.10-0.20 m and 0.20-0.30 m in five locations were collected randomly, within each production system and in the forest fragment. To evaluate the microbial activity of the soil, soil samples were collected at the 0-0.10 m layer also in five locations. All uses showed changes in physical characteristics, when compared to natural conditions. In the microbiological analysis, the integrated systems did not present significant differences in relation to the organic matter and the basal respiration of the soil when compared with the conventional systems and the forest fragment. The carbon of the microbial biomass of the soil and the metabolic quotient showed a difference between the systems of use and the preserved area.

ABSTRACT The coffee sector is estimated to have a retail market value in excess of USD 83 billion, and over 125 million jobs have been created in the global coffee chain. The coffee specialty market has recently increased significantly, generating opportunities to certify coffee beans produced by sustainable practices. This avoids practices potentially harmful to the environment. Agroforestry, organic farming, intercropping, and soil conservation strategies are examples of sustainable alternatives in the production of coffee. In this review, we focus on practices for the sustainable management of coffee plantations that can help farmers fight problems caused by global warming. More specifically, we address soil organic matter and microbiota, the use of Urochloa grass as intercrop in coffee plantations, shading systems (including agroforestry), and organic coffee production. We concluded that from the agronomic viewpoint, we already have production techniques that can replace traditional ones with significant advantages accruing to the quality of coffee orchard ecosystems. Nevertheless, we need scientific research efforts to deal with the existing gaps and the engagement of the whole coffee chain as a means of guaranteeing an adequate profit to those smallholders who adopt and maintain sustainable practice and are capable of bringing several positive changes to the coffee crop, including the use of microbia-based commercial products and new organic sources of nutrients to complement chemical fertilizers and improve coffee quality.

Resumen La disrupción económica y social generada por el COVID-19 incrementó la investigación y nuestro conocimiento sobre la transformación digital; sin embargo, carecemos de una definición formal conceptual de transformación digital. Un concepto claro y conciso, a partir de definiciones existentes en la literatura, es necesario para la investigación empírica en el campo de gerencia y negocios. Utilizar el método de descomposición semántica nos permite alcanzar el objetivo de investigación y construir una definición formal conceptual manejable y fácil de entender, donde se define la transformación digital como “un proceso que tiene como objetivo mejorar la sociedad desencadenando cambios significativos en el modelo de negocio de las empresas a través del uso de tecnologías digitales”. Los resultados consistentes y medibles que genera una definición formal conceptual apuntalan la investigación académica y permiten a los profesionales explotar nuevo conocimiento esencial al momento de adaptar el modelo de negocio a la nueva realidad digital.

Abstract Economic and social disruption generated by COVID-19 increased research on digital transformation processes; however, consensus about the formal conceptual definition of digital transformation is yet to be reached. A concise and clear concept built using existing definitions in literature is needed for empirical research in the business and management fields. Using semantic decomposition method to systematically decompose the extant definitions collected from the business literature, this study proposes the following formal conceptual definition of digital transformation: “a process that aims to improve society by triggering significant changes to the enterprise business model using digital technologies”. Consistent measurable properties caused by a formal conceptual definition support academic research and enable practitioners to exploit new knowledge essential when adapting the firm's business model to the new digital reality.

ABSTRACT COVID-19 is a multisystemic disease, with functional and late consequences still under study. Psychological and neurocognitive sequelae impact workers’ quality of life and may compromise the Work Ability (WA). The objective was to investigate the WA of people infected with SARS-CoV-2, correlating it with the assessment of sleepiness, anxiety, depression and fatigue. Cross-sectional study, involving workers diagnosed with COVID-19 under follow-up at the Department of Neurology of Universidade Estadual de Campinas (UNICAMP). Application of the Work Ability Index (WAI) analyzed with sociodemographic and occupational variables, as well the sleepiness, anxiety, depression and fatigue scales. Multiple logistic regression analysis was performed. 119 workers participated in the study and, among them, more than half had WA impairment (52.9%). Emotional disorders were the most frequent reported problem (31.9%). Multiple logistic regression showed that the interaction between anxiety and sleepiness was associated with WA impairment (OR=4.50, p=0.002). Anxiety and sleepiness were associated with previous COVID-19 and they were associated with WA impairment among workers. This study shows the WA evaluation should be provided for all workers with a previous history of COVID-19, when they return to work. This assessment can guide health promotion actions, functional rehabilitation and work adaptation to the sequelae presented by workers, singularly.

RESUMO A Covid-19 é uma doença multissistêmica e consequências funcionais e tardias estão em estudo. Sequelas psicológicas e neurocognitivas podem comprometer a Capacidade para o Trabalho (CT) dos trabalhadores. Objetivou-se investigar a CT de pessoas previamente infectadas pelo Sars-CoV-2, correlacionando-a com avaliação da sonolência, ansiedade, depressão e fadiga. Estudo transversal, com trabalhadores diagnosticados com Covid-19 e em acompanhamento no Serviço de Neurologia da Universidade Estadual de Campinas (Unicamp). Aplicou-se o instrumento Índice de Capacidade para o Trabalho (ICT), um formulário com dados sociodemográficos e ocupacionais, bem como escalas de sonolência, ansiedade, depressão e fadiga. Dos 119 trabalhadores que participaram do estudo, mais da metade apresentaram comprometimento da CT (52,9%). Distúrbio emocional foi o agravo relatado mais frequente (31,9%). A regressão logística múltipla mostrou que a interação entre ansiedade e sonolência esteve associada ao comprometimento da CT (OR=4,50 com p=0,002). Ansiedade e sonolência foram alterações tardias da Covid-19 e associadas ao comprometimento da CT dos trabalhadores avaliados. Este estudo demonstra a necessidade de que todos os trabalhadores com teste positivo por Covid-19 tenham sua CT avaliada por ocasião do retorno ao trabalho. Ações de promoção à saúde, reabilitação funcional e adaptação do trabalho de acordo com as sequelas apresentadas pelos trabalhadores.

Resumen Objetivo: Describir la evolución de las cadenas livianas libres séricas (CLL) en el período comprendido entre el trasplante cardíaco ortotópico (TCO) y el trasplante de células progenitoras hematopoyéticas (TCPH), la respuesta hematológica al año tras el TCPH y el tratamiento quimioterápico e inmunosupresor en pacientes con amiloidosis AL. Método: Serie de casos de pacientes consecutivos con diagnóstico de amiloidosis AL que recibieron TCO seguido de TCPH del Registro Institucional de Amiloidosis del Hospital Italiano de Buenos Aires, entre enero de 2010 y noviembre de 2021. Se reportaron los valores de CLL entre trasplantes y al año del TCPH. Las variables cuantitativas se describieron como mediana e intervalo intercuartil, y las variables categóricas como frecuencias absolutas y relativas. Resultados: De 106 pacientes con amiloidosis AL, seis tuvieron TCO seguido de TCPH. La mediana de edad fue de 55 años. La mayoría eran hombres (n = 5). En el período entre trasplantes, la CLL involucrada disminuyó en dos pacientes y se mantuvo estable en tres. Todos lograron la remisión hematológica completa al año del TCPH. Un solo paciente presentó recaída en el órgano sólido trasplantado. Tacrolimus, micofenolato de mofetilo y corticoides fue el esquema inmunosupresor utilizado después del TCO. Conclusiones: El TCO representa una opción de tratamiento en pacientes con falla cardíaca grave por amiloidosis, permitiendo luego un tratamiento intensivo con quimioterapia de inducción y TCPH. Si bien faltan estudios, la terapia inmunosupresora después del TCO podría tener algún efecto sobre las células plasmáticas clonales.

Abstract Objective: To describe the evolution of serum free light chains (FLC) in the period between orthotopic heart transplantation (OHT) and autologous stem cell transplantation (ASCT), the hematological response one year after ASCT and chemotherapy and immunosuppressive treatment in patients with AL amyloidosis. Method: Case series of consecutive patients diagnosed with AL amyloidosis who received OHT followed by ASCT from the Institutional Registry of Amyloidosis of the Italian Hospital of Buenos Aires, between January 2010 and November 2021. FLC values between transplants and at year post ASCT. Quantitative variables were described with their median and interquartile range. Categorical variables as absolute and relative frequencies. Results: Of 106 patients with AL amyloidosis, 6 had an OHT followed by ASCT. The median age was 55 years. Most were men (n = 5). In the period between transplants, the involved CLL decreased in two patients and remained stable in three. All achieved complete hematologic remission 1 year after ASCT. A single patient presented relapse in the transplanted solid organ. Tacrolimus, mycophenolate mofetil, and corticosteroids were the immunosuppressive regimen used after OHT. Conclusions: OHT represents a treatment option in patients with severe heart failure due to amyloidosis, allowing later intensive treatment with induction chemotherapy and ASCT. Although studies are lacking, immunosuppressive therapy after OHT might have some effect on clonal plasma cells.

Resumen: En el presente artículo compartimos los avances de la investigación que estamos impulsando en la Universidad Nacional de Quilmes, desde el proyecto de Emprendimientos sociales y salud comunitaria. En el objetivo general, nos propusimos estudiar en profundidad las transformaciones subjetivas que ocurren en el marco de las experiencias de cooperación social, con el fin de identificar y comprender los elementos que condicionan su expansión, así como aquellos tendientes al fortalecimiento del campo de la Economía Social y Solidaria (ESS). En ese sentido, abordamos la temática de la cooperación social entendiendo que la misma a través de experiencias socio-económicas favorece el acceso a los derechos - trabajo, educación y salud- de las personas en situación de vulnerabilidad. Del amplio campo de la cooperación social nos focalizamos más puntualmente en el estudio de las empresas sociales, es decir, esas organizaciones asociativas que realizan una actividad económica regular de producción de bienes o prestación de servicios con una definida finalidad social para la comunidad y la integración social de las personas, particularmente de los grupos socialmente vulnerables y vulnerados.Entre las reflexiones finales que venimos construyendo destacamos que entre los testimonios de les emprendedores, lo colectivo surge como estructurante de la organización, en tal sentido es acto participativo, es nosotres, horizontalidad y confianza. Ese nosotres es inclusivo y diverso. Se considera saludable ya que da marco a lo que se construye y a su vez oficia como un espacio simbólico productor de procesos identificatorios de les emprendedores con la organización.

Abstract: In this article we want to share the progress of the research that we are carrying out at the National University of Quilmes, from the Social Entrepreneurship and Community Health project. In the general objective of this project, we proposed to study in depth the subjective transformations that occur within the framework of social cooperation experiences, in order to identify and understand the elements that condition its expansion, as well as those tending to strengthen the field of the Social and Solidarity Economy (ESS). In this sense, we address the issue of social cooperation, understanding that it through socio-economic experiences favors access to rights - work, education and health - of people in vulnerable situations. From the broad field of social cooperation, we focus more specifically on the study of social enterprises, that is, those associative organizations that carry out a regular economic activity of producing goods or providing services with a defined social purpose, for the community and the social integration of people, particularly of socially vulnerable and vulnerable groups. Among the final reflections that we have been building, we are interested in highlighting that among the testimonies of the entrepreneurs, the collective emerges as a structuring of the organization, in this sense it is a participatory act, it is us, horizontality and trust. We are inclusive and diverse. It is considered healthy since it provides a framework for what is built and, in turn, acts as a symbolic space that produces identification processes of the entrepreneurs with the organization.

Resumo: Neste artigo queremos compartilhar o andamento da pesquisa que estamos realizando na Universidade Nacional de Quilmes, a partir do projeto Empreendedorismo Social e Saúde Comunitária. No objetivo geral deste projeto, nos propusemos a estudar em profundidade as transformações subjetivas que ocorrem no âmbito das experiências de cooperação social, a fim de identificar e compreender os elementos que condicionam sua expansão, bem como aqueles que tendem a fortalecer o campo da Economia Social e Solidária (ESS). Nesse sentido, abordamos a questão da cooperação social, entendendo que ela, por meio de experiências socioeconômicas, favorece o acesso a direitos - trabalho, educação e saúde - de pessoas em situação de vulnerabilidade. Do amplo campo da cooperação social, focamos mais especificamente no estudo do que se convencionou chamar de empresas sociais, ou seja, aquelas organizações associativas que desenvolvem uma atividade econômica regular de produção de bens ou prestação de serviços com finalidade social definida comunidade e a integração social das pessoas, em particular dos grupos socialmente vulneráveis e vulneráveis. Dentre as reflexões finais que fomos construindo, nos interessa destacar que dentre os depoimentos dos empreendedores, o coletivo surge como estruturante da organização, nesse sentido é um ato participativo, somos nós, horizontalidade e confiança. Que somos inclusivos e diversos. É considerado salutar por fornecer um arcabouço para o que é construído e, por sua vez, atuar como um espaço simbólico que produz processos de identificação dos empreendedores com a organização.
