Educación infantil, pandemiay reflexiones acerca del derribar muros

O texto objetiva tratarda Educação Infantil no contexto da pandemia da COVID-19, considerando as orientações legais da Base Nacional Comum Curricular e das Diretrizes Curriculares Nacionais para Educação Infantil. Realizamos uma reflexão exploratória sobre o momento histórico e de crise vivido no ano de 2020 com a pandemia, e, posteriormente, apresentamosuma aproximação conceitual com o processo de desemparedamento como forma de interaturar com as infâncias e com a Educação Infantil a partir de uma educação mais coletiva e humana.Concluímos que o desemparedamento das infâncias e das escolas de Educação Infantil pode se tornar uma prática e uma experiência nesses novos tempos de retorno àpresencialidade nas escolas. Tempos estes que estamos sendo desafiadas e desafiados a transformar bruscamente nossa prática pedagógica, exigindo de nós ações diversas, por vezes,poucas reflexões, novos desafios e incontáveis desacomodações.The text aims to address Early Childhood Education within the context of the COVID-19 pandemic, considering the legal guidelines of the Base Nacional Comum Curricular (Common National Curriculum Base) and the Diretrizes Curriculares Nacionais para Educação Infantil (the National Curriculum Guidelines for Early Childhood Education). We carried out an exploratory reflection on the historical moment and crisis experienced in 2020 due to the pandemic, and later presented a conceptual approach with the process of knocking down of walls as a way to interact with childhoods and with Early Childhood Education from a more collective and humane educational approach. We concluded that the knocking down of walls that confine childhoods and Early Childhood Education schools can become a practice and an experience in these challenging new times of a return to attendance in schools; a period in which we are being challenged to abruptly transform our pedagogical practice, requiring from us diverse actions, new challenges as well as countless disaccommodations and leaving, sometimes, little chance for thought.El texto tiene el objetivo de abordar la Educación Infantil en el contexto pandémico causado por el COVID-19, considerando las directrices legales de la Base Nacional Común Curricular y de las Directrices Curriculares Nacionales para la Educación Infantil.Desarrollamos una reflexión exploratoria sobre el momento histórico y de crisis vivido en 2020 con la pandemia, y, luego, presentamos un acercamiento con los conceptos del proceso de derribar muros, como forma de interaccionar con las infancias y con la Educación Infantil a partir de una educación más colectiva y humana. Concluimos que derribar las barreras de las infancias y de las escuelas de educación infantil pueden tornarse una práctica y una experiencia en estos nuevos tiempos de retorno a la presencialidad en las escuelas. Tiempos estos que nos desafían a transformar bruscamente nuestra práctica pedagógica, exigiéndonos acciones múltiples, a veces pocas reflexiones, nuevos desafíos e incontables incomodidades

Incidence and factors associated with pericardial effusion after cardiac valve surgery

Introduction: Pericardial effusion (PE) is a postoperative complication of cardiac valve surgery, related to early hospital readmissions and death. We aimed to describe its incidence and to identify predictive factors of moderate-to-severe PE in a contemporary cohort. Methods: We retrospectively reviewed medical records of all consecutive patients submitted to cardiac valve surgery in a tertiary teaching hospital from January 2012 to July 2014, where echocardiography was routinely performed before patient discharge. Moderate-to-severe PE was defined as ≥ 10 mm of thickness, or signs of cardiac tamponade on echocardiography. Additional clinical and perioperative data were extracted from medical records using a standardized protocol. Results: Of 353 patients, 335 underwent a predischarge echocardiography. From these, 27 patients (8%; mean age: 62 years; standard deviation 12 years; 70% male) had moderate-to-severe PE. These patients had a higher prevalence of previous stroke (22% vs. 8%; p = 0.009) and oral anticoagulation (international normalized ratio > 2) prior to the surgery (11 vs. 2%; P = 0.002). In patients with moderate-to-severe PE, surgeries had longer ischemia (p < 0.001) and cardiopulmonary bypass (p < 0.001) times, and the prevalence of postoperative atrial fibrillation was higher (56% vs. 32%; p = 0.011) than in patients with absent or small PE. Hospital mortality was also higher (15% vs. 3%; p = 0.002) in patients with moderate-to-severe PE. Conclusions: Eight percent of patients submitted to cardiac valve surgery developed moderate-to-severe PE. Moreover, PE was associated with pre- and post-surgery conditions likely related to the coagulation state, though a cause-effect relationship could not be inferred. Noteworthy, this condition was associated with higher in-hospital morbidity and mortality.Keywords: Adult; pericardium; postoperative car

Capacidad para el trabajo y síntomas osteomusculares en trabajadores de un hospital público

El objetivo de este estudio fue conocer el perfil sociodemográfico, identificar las quejas osteomusculares y evaluar la capacidad para el trabajo de los trabajadores de un hospital público. Es un estudio cuantitativo, analítico y transversal. 31 servidores del Hospital das Clínicas de la Facultad de Medicina de Ribeirão Preto de la Universidad de São Paulo y de la Unidad de Emergencia de Ribeirão Preto fueron evaluados y encaminados al servicio de Fisioterapia en el Centro de Rehabilitación en el período de mayo a diciembre de 2012. Dos cuestionarios fueron aplicados: el Cuestionario Nórdico de Síntomas Osteomusculares, de carácter sociodemográfico y desarrollado por los pesquisidores deste estudio, para la tipificación y mensuración de relatos de los síntomas osteomusculares, y el Cuestionario Índice de Capacidad para el Trabajo, que posibilita la evaluación y detección precoz de alteraciones en la calidad de vida de los trabajadores. Los 31 evaluados tienen, en media, 46,5±11,8 años, siendo 27 mujeres y 4 hombres. Las ocupaciones con mayor prevalencia fueron: auxiliar de enfermería (19,3%), auxiliar de servicios (19,3%) y tesoreros (16,13%). 74,2% no practican actividades físicas, 38,7% tienen más de 20 años en el servicio y 64,5% pasan mucho tiempo de pie. La mayoría de las quejas osteomusculares tenía relación con las rodillas, después con los hombros y lumbar. La media del Índice de Capacidad para el Trabajo fue de 33,84±8,35, revelando una capacidad para el trabajo moderada. Los resultados presentados muestran la necesidad de la evaluación de las condiciones laborales, basada en una evaluación ergonómica con base en los aspectos físicos, cognitivos y organizacionales, cómo estrategia correctiva y/o preventiva de las lesiones osteomusculares y de la mejoría de la capacidad de realización del trabajo.O objetivo do estudo foi conhecer o perfil sociodemográfico, identificar as queixas osteomusculares e avaliar a capacidade para o trabalho de trabalhadores de um hospital público.

A total of 31 workers reviews have, on average, 46.5±11.8 years, being 27 women and 4 men. The prevalent occupations were: nursing assistant (19.3 %), auxiliary services (19.3 %) and clerks (16.13%). A number of 74.2 % did not engage in physical activity, 38.7 % have more than 20 years in service and 64.5 % are most of the time standing. The higher prevalence of musculoskeletal complaints was related to the knees, followed by shoulders and lower back. The average Index Capacity for Work was 33.84±8.35, revealing a moderate capacity to work. The presented results indicate the need to evaluate working conditions, based on an ergonomic evaluation consisted of physical, cognitive and organizational aspects of work, as well as corrective and/or preventive strategy of musculoskeletal injuries and improvements of the capacity to work

Docencia en educación física y maternidades : construyendo otras interrrelaciones

Este artigo objetiva refletir sobre a maternidade e os modos de viver essa experiência que impactam e são impactados pela docência em Educação Física na Educação Básica e no Ensino Superior, em Porto Alegre/RS e região metropolitana. A temática abordada se fundamenta na análise das interpretações de dois grupos de discussão, constituídos como estratégia metodológica e das informações obtidas que possibilitaram a construção de uma categoria de análise em uma pesquisa de Doutorado. As análises e as interpretações da pesquisa indicam que as professoras participantes do estudo percebem que apesar da maternidade ser uma experiência vivida de modo individual, cercada de exigências sociais e que localiza na mulher significativa responsabilidade pela criação dos/as filhos/as, há possibilidades de se conceitualizar e viver outras experiências de maternar de modo mais coletivo e comunitário.This article aims to reflect on motherhood and the ways of living this experience which impact and are impacted by teaching in Physical Education, Basic Education and Higher Education in Porto Alegre/Rio Grande do Sul/Brazil and metropolitan area. The theme addressed is based on the analysis of the interpretations of two discussion groups constituted as a methodological strategy and on information obtained that allowed the construction of a category of a Doctoral research. The analyzes and interpretations of the research indicate that the teachers collaborating in the study realize that despite motherhood being an experience lived individually, surrounded by social demands and which places significant responsibility for raising children on women, there are possibilities to conceptualize and live other experiences of mothering in a way that is more collective and communal.Este artículo busca reflexionar sobre la maternidad y los modos de vivir esta experiencia que impactan y son impactados por la docencia en Educación Física, de la Educación Básica y de la Enseñanza Superior en Porto Alegre/RS y región metropolitana.

Management of anticoagulation with vitamin K antagonists in a tertiary hospital outpatient clinic

Introduction: atrial fibrillation (AF) is one of the main risk factors for stroke. Vitamin K antagonists (VKA) reduce this risk, and the effectiveness of this treatment is directly related to time in therapeutic range (TTR). This study aimed to report the TTR in patients with non-valvular AF at an anticoagulation outpatient clinic; and to describe the profile of this population of patients in terms of risk of stroke, as well as the occurrence of adverse events during the follow-up. Methods: Retrospective cohort study involving patients of the anticoagulation outpatient clinic of the Department of Internal Medicine at Hospital de Clínicas de Porto Alegre. We evaluated outpatient visits, hospital admissions, and emergency visits from January to December 2011. TTR was calculated using the Rosendaal method. Results: Sixty-three patients were investigated. Their mean age was 74.3±10.9 years. The CHADS2 score was ≥ 4 in 44.5% of the patients; 63.5% of them had a CHA2DS2-VASc score ≥ 5. The TTR was 64.8%. During follow-up, the incidence of overall bleeding was 31.7%, with major and minor bleeding rates of 4.8% and 34.9%, respectively. There were no other complications related to AF or anticoagulation. Conclusion: The patients achieved a TTR of 64.8% during follow-up, which is deemed appropriate and in agreement with the literature. Patients had high risk for stroke, and the incidence of minor bleeding was higher than the rate found in the literature, whereas the incidence of major bleeding was similar to the one found in previous studies
