Abstract The presence of generalized lymphadenopathy has usually been associated with systemic lupus erythematosus (SLE), however, it is not usual to find this finding as an initial manifestation of the disease. There are multiple differential diagnoses that include Kikuchi histiocytic necrotizing lymphadenitis, Castleman disease, infections and lymphoma when this finding is presented as an initial symptom of SLE. We present the case of a 56-year-old man who presented with 2 months of generalized lymphadenopathy without examination findings or history suggesting a diagnosis of SLE; Lymphoma or infectious disease was initially suspected and an exhaustive study was performed, including cervical lymph node biopsy. Laboratory investigation finally revealed leukopenia, significant proteinuria, positive ANA, positive anti-dsDNA, and hypocomplementemia, confirming the diagnosis of SLE-type autoimmune disease. This case illustrates the importance of recognizing this unusual presentation, given that it is a potentially fatal disease.

Resumen La presencia de linfadenopatías generalizadas se ha asociado de forma usual con lupus eritematoso sistémico (LES), sin embargo, no es usual encontrar este hallazgo como manifestación inicial de la enfermedad.

Presentamos el caso de un hombre de 56 años que se presentó con 2 meses de linfadenopatía generalizada sin datos al examen o antecedentes que sugirieran diagnóstico de LES; se sospechó inicialmente linfoma o enfermedad infecciosa y se realizó un estudio exhaustivo incluido biopsia de ganglio cervical. La investigación de laboratorio finalmente reveló leucopenia, proteinuria significativa, ANA y anti-dsDNA positivos e hipocomplementemia, lo que confirma el diagnóstico de enfermedad autoinmune tipo LES. Este caso ilustra la importancia de reconocer esta forma de presentación inusual, dado que se trata de una enfermedad potencialmente fatal.

Resumen En este artículo estudiamos cómo se movilizó el sentido para proponer un experimento que dio inicio a una secuencia didáctica sobre la luz. Ésta fue elaborada en un grupo de trabajo donde colaboraron docentes con investigadoras y fue implementada en diferentes aulas de primaria de un programa socioeducativo de Buenos Aires. Interesa explorar la potencialidad de esta modalidad colaborativa para propiciar la construcción de conocimiento didáctico. Se trata de un estudio de caso donde analizamos las interacciones entre las diferentes posturas de los integrantes cuando codiseñaron, implementaron y analizaron la secuencia. Identificamos que, al inicio, las discusiones del grupo estuvieron enfocadas en aspectos materiales de la planificación, pero, luego, la reflexión compartida sobre las escenas de aula posibilitó repensar las intervenciones docentes, las ideas de los alumnos y la evaluación de alternativas sobre cómo convocarlos, lo que motivó modificaciones en nuevas implementaciones y redefiniciones sobre los sentidos para proponer el experimento. Por último, pudimos comprender algunas razones que obstaculizan la aproximación de los docentes a las producciones de la investigación académica.

Abstract In this paper, we study how the intentionality to propose an experimental situation in a science lesson was mobilized. This situation initiated a didactic sequence about light that was implemented in different elementary classrooms (belonging to a socio-educational program from the City of Buenos Aires) and was conceived in a working group where teachers and researchers collaborate. We aim to explore the potentiality of this collaborative modality to promote the construction of ideas on teaching and learning science. We present a case study and we focus on the interactions between the different positions of the collaborative group members as they were involved in the co-design, implementation, and analysis of the sequence. We identified that, initially, the group discussions were centered on the material aspects of the lesson design; but, after the first implementations, the shared reflection about the classroom scenes made it possible to problematize the teachers’ interventions, the interpretation of the students’ ideas and the assessment of alternatives on how to promote student engagement. This motivated modifications in further implementations and redefinitions of the purpose to present the experiment in class. Finally, we were able to understand some reasons that obstruct teachers’ engagement with academic research proposals.

Abstract Policy evaluation and guidance on fluoride use and sugar consumption in Latin American and Caribbean countries (LACC) may provide a scientific evidence basis for policymakers, dental professionals, civil society organizations and individuals committed to improving public oral health. A cross-sectional study was conducted to evaluate the extent of implementation of policies/guidelines on fluoride use, and sugar consumption in LACC. The study had two stages. First a questionnaire covering four major areas was developed: fluoridation of public water supplies; salt fluoridation; fluoride dentifrices, and sugar consumption. Then, the questionnaire was applied to collect data among representative participants in public oral health from LACC. Ninety-six participants from 18 LACC answered the questionnaire. One-hundred seventy documents were attached, and 285 links of websites were provided by the respondents. Implementation of policies and guidelines on water and table salt fluoridation and processed and ultra-processed food consumption were found in most countries, with some issues in the consensus and coverage. Thus, differences were identified in the extent of implementation of public oral health strategies on sugar consumption and fluoridation among the countries. There is no consensus on the policies in LACC to reduce sugar consumption and for the use of fluoride. A few policies and guidelines were applied in isolated countries, with a variety of strategies and standards. For future actions, it will be important to encourage the development of strategies and public policies within countries, and to evaluate the effectiveness of existing policies in reducing dental caries and in improving oral health in LACC.

Abstract The aim of this multicenter study was to explore the early-life sugar consumption and dietary practices in Latin America as well as to investigate the association between breastfeeding duration and the age at which foods and beverages with added sugars are introduced. A cross-sectional study was conducted with 805 1- to 3-year-old children from 10 Latin American countries, as a complementary study to the Research Observatory for Dental Caries of the Latin American Region (OICAL). A Food Frequency Questionnaire previously tested in different countries was applied to children’s mothers and data on breastfeeding and age at introduction of sugary foods and beverages was collected. Statistical analysis included the Kruskal-Wallis test and Poisson regression with robust variance, with the calculation of crude and adjusted mean ratios (MR) and 95% of confidence intervals (CI). The average age at introduction of sugary foods and beverages was 10.1 months (95%CI 9.7–10.4) and 9.6 (95%CI 9.2–9.9) months, respectively, with a significant variation between countries (p < 0.001). The average daily frequency of sugary foods-beverages was 3.3 times per day (95%CI 3.1–3.5) and varied significantly between countries (p = 0.004). Breastfeeding duration of over six months was associated with an increase in the age of introduction of sweet drinks (16%; MR 1.16; 95%CI 1.05–1.28) and foods (21%; MR 1.21; 95%CI 1.10–1.33). In conclusion, most children from vulnerable settings in Latin America start consuming sugary products in the first year of life and a high frequency of consumption was reported through early childhood. Additionally, breastfeeding contributes to a delay in the introduction of sugary products. earlylife introduced crosssectional cross sectional 80 1 3yearold yearold 3 old OICAL. OICAL .

Abstract The aim of this study was to describe the initial oral microbiota and how delivery mode and feeding practices impact its diversity in 0-2-month-old infants. This was a cross-sectional study that consisted of one collection of saliva samples from 0-2-month infants at baseline. Ten pairs of mothers and infants were selected. Medical health history, pregnancy, birth, feeding practices (breastfeeding or milk formula), and infant health status was obtained. Pooled microbial samples were obtained from the oral surfaces using a sterile cotton swab. Infants did not receive any breast milk before sampling. After collection, each swab was analyzed through microbiological culture-based procedures, using selective mediums. Cultures were analyzed for the presence of Streptococci, Lactobacillus, Staphylococcus, Enterobacterium , and Candida albicans . Twenty percent of the samples were serially diluted (10-2) to assess the number of bacteria expressed as CFU. Bacillota was the leading phylogenetic group in the infant’s pooled microbial sample. The most prevalent genera were Streptococcus, Lactobacillus , and Staphylococcus . Two participants had a positive growth of Candida albicans . The association between genus group, type of delivery, and feeding practices was not statistically significant (p > 0.05). Lactobacillus genus was frequently present in the cesarean delivery group but with slightly higher counts in a vaginal delivery study subject. Exclusively breastfed infants showed presence of Streptococcus, Lactobacillus, Staphylococcus . The oral microbiome in infants (0-2 month-old) is highly heterogeneous and dynamic. Microbiota composition seems to be impacted by mode of delivery, with slight differences among groups. Breastmilk appears as an essential factor in maintaining the oral microbiome’s stability and diversity. 02monthold monthold 0 2 month old crosssectional cross sectional 02month baseline selected history pregnancy birth breastfeeding formula, formula formula) sampling culturebased culture based procedures mediums Streptococci 102 10 (10-2 CFU s sample Streptococcus p 0.05. 005 0.05 05 0.05) subject 02 (0- month-old dynamic groups microbiomes 1 (10- 00 0.0 (0 (10 0.

RESUMEN La lengua azul (LA) es una enfermedad viral que afecta a los rumiantes domésticos y salvajes. El agente etiológico de esta enfermedad es el virus de la lengua azul (VLA) que se transmite principalmente por vectores hematófagos del género Culicoides y tiene una distribución global. Cuba se encuentra en una zona de circulación endémica del virus y a pesar que desde el año 2007 se reporta a la Organización Mundial de la Sanidad Animal (OMSA) la presencia de bovinos seroreactores, no existen evidencias de manifestaciones clínicas de la enfermedad ni se ha aislado el virus. El objetivo del presente trabajo fue aislar e identificar el virus de la lengua azul a partir de la sangre de un ternero naturalmente infectado de la provincia Mayabeque en 2018. El virus fue aislado en huevos embrionados de pollo y en cultivo celular a partir de la sangre del ternero a los 21 días de edad que resultó positiva a la presencia de virus por un ensayo de reverso transcripción acoplada a la reacción en cadena de la polimerasa anidada (nRT-PCR). Los embriones inoculados mostraron mortalidad embrionaria, disminución de la talla, coloración rojiza y/o edema como indicativo de multiplicación viral. En el cultivo celular se observaron focos de células redondeadas y refráctiles. La identificación del virus se realizó por los ensayos de nRT-PCR, un Kit comercial de RT-PCR en tiempo real (rRT-PCR) y rRT-PCR basado en SYBR Green-I para la detección especifica del VLA.

ABSTRACT Bluetongue (BT) is a viral disease that affects domestic and wild ruminants. The etiological agent of this disease is bluetongue virus (BTV) which is mostly transmitted by blood-borne vectors of the Culicoides genus and has a global distribution. Cuba is located in a zone of endemic circulation of the virus. Although the presence of bovine reactors has been reported to the World Organization for Animal Health (WOAH) since 2007, there is no evidence of clinical manifestations of the disease and the virus has not been isolated. This work aimed to isolate and identify bluetongue virus from the blood of a naturally infected calf from Mayabeque province in 2018. The virus was isolated in chicken embryonated eggs and in cell culture from the blood of the calf at 21 days of age, which tested positive for the presence of virus by a nested reverse transcription polymerase chain reaction assay (nRT-PCR). The inoculated embryos showed embryonic mortality, decreased size, reddish coloration and/or edema as indicative of viral multiplication. In cell culture, rounded and refractile cell foci were observed. Virus identification was performed by nRT-PCR assays, a commercial real-time RT-PCR kit (rRT-PCR) and rRT-PCR based on SYBR Green-I for specific detection of BTV.

Resumen Objetivo: presentar los aprendizajes de una sistematización como método, para la construcción de conocimiento basado en la experiencia vivida por los propios investigadores de varios proyectos sobre la educación en crianza, en el campo de la salud pública, llevado a cabo en la vereda Granizal, Antioquia, durante el período 2013-2019. Materiales y método: se empleó la sistematización de experiencias y los participantes fueron los mismos investigadores. Se inició con la organización de los materiales, los diarios de campo de los círculos de investigación temática y relatorías de las reuniones del equipo de investigación y de los actores comunitarios. Se siguió con la elaboración de una matriz con la recuperación histórica. Y, finalmente, de las reflexiones grupales, surgieron categorías y relaciones para la construcción teórica de visión de conjunto. Resultados: se presenta la propuesta teórica de la sistematización y los procedimientos para implementarla, orientada por cinco momentos: vivir la experiencia, formular un plan de sistematización, recuperar el proceso vivido, las reflexiones de fondo y los puntos de llegada. Se destacan cuatro rasgos de la sistematización: una investigación creativa; basada en un proceso de construcción colectiva; para aprender de la práctica y construir conocimiento; y como escenario transformador de esta y de quienes la realizaron. Conclusión: la “sistematización de la sistematización” permitió hacer conciencia sobre la propia praxis investigativa. Muestra la comprensión del grupo acerca de la conceptualización y metodología de esta perspectiva investigativa. Trasciende la recopilación y organización de la información del proceso vivido en la medida en que la reconstrucción de la experiencia es una comprensión más amplia que transforma la práctica de los sujetos involucrados.

Resumo Objetivo: apresentar as aprendizagens de uma sistematização como método, para a construção de conhecimento baseado na experiência vivida pelos próprios pesquisadores de vários projetos sobre a educação em criação, no campo da saúde pública, levado a cabo no povoado Granizal, Antioquia, durante o período 2013-2019. Materiais e método: utilizou-se a sistematização de experiências os participantes foram os mesmos pesquisadores. Iniciou-se com a organização dos materiais, os diários de campo dos círculos de pesquisa temática e relatorias das reuniões da equipe de pesquisa e dos atores comunitários. Conseguiu-se com a elaboração de uma matriz com a recuperação histórica. E, finalmente, das reflexões grupais, surgiram categorias e relações para a construção teórica de visão de conjunto. Resultados: apresenta-se a proposta teórica da sistematização e os procedimentos para implementá-la, orientada por cinco momentos: viver a experiência, formular um plano de sistematização, recuperar os processos vividos, as reflexões de fundo e os pontos de chegada. Destacam-se quatro rasgos da sistematização: uma pesquisa criativa; baseada em um processo de construção coletiva; para aprender da prática e construir conhecimento; e como cenário transformador desta e de quem a realizaram. Conclusão: a “sistematização da sistematização” permitiu fazer consciência sobre a própria práxis pesquisaria. Amostra a compreensão do grupo acerca da conceptualização e metodologia desta perspectiva pesquisaria. Trascende a recopilação e organização da informação do processo vivido na medida em que a reconstrução da experiência é uma compreensão mais ampla que transforma a prática dos sujeitos envolvidos.

Abstract Objective: to present the learning of a systematization as a method, for the construction of knowledge based on the experience lived by the researchers of several projects on parenting education in the field of public health carried out in the rural settlement of Granizal, Antioquia, during the period 2013-2019. Materials and method: the systematization of experiences was used and the participants were the researchers. It began with the organization of the materials, the field diaries of the thematic research circles and reports of the meetings of the research team and community actors. It was continued with the elaboration of a matrix with the historical recovery. And, finally, reflections, categories and relationships emerged from the group for the theoretical construction of the overall vision. Results: the theoretical proposal of the systematization and the procedures to implement it are presented, guided by five moments: living the experience, formulating a systematization plan, recovering the lived process, the background reflections and the arrival points. Four features of systematization stand out: creative research; research based on a process of collective construction; learning from practice and building knowledge; and as a transforming scenario of this research and of those who carried it out. Conclusion: the “systematization of the systematization” allowed raising awareness of the research praxis itself. It shows the understanding of the group on conceptualization and methodology of this research perspective. It transcends the collection and organization of the information of the process lived to the extent that the reconstruction of the experience is a broader understanding that transforms the practice of the subjects involved.

Abstract Given the polysemic and multidimensional nature of the notion of quality and its centrality and growing relevance in higher education, it is necessary to lay the foundations for conceptualizing it in terms of its context of application, in order to provide support and consistency to the design of specific policies. This paper presents the main methodological guidelines and findings of an exhaustive literature review focused on identifying the conceptions of quality in higher education in papers published in high-impact international journals between 2016-2020. Following the axial guidelines of the PRISMA-P method, 186 articles were selected out of 53,290 identified as part of the initial universe. Using open deductive coding, prevailing conceptions of the quality of higher education and its valued components were identified. Another noteworthy finding is the relevance of grouping these conceptions into two categories –“quality en soi” and “quality pour soi”– which are very similar to the positions taken in two very influential publications in Latin America. A crucial question arose as a consequence of the analysis of the articles submitted for review: who is responsible for determining the quality of a product or service in higher education? The answer to this question gave rise to the emergence of an alternative theoretical and conceptual positioning to those underlying the two categories: “quality pour qui” (quality for whom).

Resumen Dado el carácter polisémico y multidimensional de la noción calidad y de su centralidad y relevancia creciente en la educación superior, resulta necesario sentar bases que permitan conceptualizarla en función de su contexto de aplicación, de modo de dar sustento y consistencia al diseño de políticas focalizadas. El artículo expone los principales lineamientos metodológicos y resultados de una exhaustiva revisión bibliográfica orientada a esos efectos, centrada en la identificación de las concepciones sobre calidad de la educación superior en artículos publicados entre 2016 y 2020 en revistas de alto impacto internacional. Una vez finalizada la revisión, que siguió los lineamientos axiales del método PRISMA-P, quedaron seleccionados 186 artículos del universo inicial de 53 290. Un análisis por codificación abierta deductiva permitió identificar las concepciones predominantes de la calidad de la educación superior y sus componentes valorados como sustantivos. Otro de los resultados destacables es la pertinencia de agrupar esas concepciones en dos categorías —“calidad en soi” y “calidad pour soi”—, muy afines con las posiciones asumidas en dos textos muy influyentes en Hispanoamérica. Del análisis de los artículos seleccionados surgió una interrogante crucial: ¿a quién le corresponde determinar la calidad de un producto o servicio en educación superior? La respuesta a esta pregunta dio lugar a la emergencia de un posicionamiento teórico-conceptual alternativo a los subyacentes en esas categorías: “calidad pour qui” (calidad para quién, calidad para quiénes).
