ABSTRACT Amid the advances in nanotechnology, the use of metal oxide nanoparticles has increased, standing out the use of copper oxide and zinc oxide, due to their abundance and their specific properties of great relevance, such as antimicrobial effects, and the improved electrical conductivity and catalysis. The bioaccumulation and interaction of this type of nanoparticles in the environment are largely unknown, generating concern about potentially toxic effects that have not yet been adequately studied, hence the importance of knowing their effects on the environment. Among the proposals for environmental studies of nanomaterials, plants stand out as bioindicators, especially after the capture of particles from the atmosphere. This review compiles information about different studies on applications of zinc oxide and copper oxide nanoparticles, how they can be detected, and how they can be captured and characterized by using plants. It also highlights the importance of studies on toxicity and the effects that are generated after the interaction with different plant species, which contribute to understanding the diverse mechanisms of toxicity, interaction, and accumulation of metals, as well as their degradation in the environment. Finally, alternatives are mentioned to improve the biocompatibility of nanoparticles with the environment and the organisms. Knowing the current state of the topic will allow to consolidate the information obtained so far and the direction to take, for the efficient and responsible use of nanotechnology, ensuring its continuity and development.

RESUMEN Con los avances de la nanotecnología ha aumentado el uso de nanopartículas óxido metálicas, entre las que destacan las de óxido de cobre y óxido de zinc, por su abundancia y por sus propiedades específicas de gran relevancia, tales como efectos antimicrobianos y la mejora de la conductividad eléctrica y la catálisis. La bioacumulación e interacción de este tipo de nanopartículas en el ambiente son desconocidos en gran parte, generando preocupación por los efectos potencialmente tóxicos que aún no han sido estudiados de forma adecuada, de ahí la importancia de conocer sus efectos en el ambiente. Entre las propuestas para los estudios ambientales de los nanomateriales, destacan las plantas como bioindicadores, en especial tras la captación de partículas desde la atmósfera. La presente revisión, recopila información de distintos estudios sobre aplicaciones de nanopartículas de óxido de zinc y óxido de cobre, la manera en que pueden detectarse, y el cómo pueden ser captadas y caracterizadas mediante el uso de plantas. También resalta la importancia de los estudios sobre la toxicidad y los efectos que se generan a través de la interacción con distintas especies de plantas, que contribuyen a entender los diversos mecanismos de toxicidad, interacción y acumulación de metales, así como su degradación en el ambiente. Finalmente, se mencionan alternativas para mejorar la biocompatibilidad de las nanopartículas con el ambiente y los organismos. El conocer el estado actual del tema permitirá consolidar la información obtenida hasta el momento y la dirección a tomar para el uso eficiente y responsable de la nanotecnología, asegurando su continuidad y desarrollo.

ABSTRACT A principle of abyssal thinking is that scientific knowledge is not equitably distributed. The university-school relationship may be read under this principle where there is a subject of knowledge (academic knowledge), and an object of knowledge (teachers and school knowledge). More specifically, we connect the problem of the (de)coloniality of power and knowledge with science education through a work of epistemic care. The case of CIDSTEM-PUCV is presented as an experimental center that challenges the traditional role of research by including the epistemic and cultural diversity that exists in schools and its communities. We reflect on the challenges of a decolonial and Latina science education capable of recognizing the plurality of knowledge with which it is related.

RESUMEN Un principio del pensamiento abismal es que el conocimiento científico no se distribuye equitativamente. La relación universidad-escuela puede leerse bajo este principio donde existe un sujeto de conocimiento, el saber académico y un objeto de conocimiento, el saber docente-escolar. Más específicamente, conectamos el problema de la (de)colonialidad del poder y el saber con la educación en ciencias a través de un trabajo de cuidado epistémico. Se presenta el caso de CIDSTEM-PUCV como un centro experimental que desafía el rol tradicional de la investigación para incluir la diversidad epistémica y cultural que existe en escuelas y sus comunidades. Reflexionamos sobre los desafíos de una educación científica decolonial y latina capaz de reconocer la pluralidad de saberes con que se relaciona.

Resumen Desde hace algunas décadas, la convergencia de medios a través de pantallas, la digitalización de los procesos comunicativos y la emergencia de nuevas prácticas informativas reconfiguran el ejercicio y la formación periodística. El presente artículo muestra los resultados de un estudio exploratorio en torno a la manera en que los estudiantes de periodismo se informan en la actualidad y discriminan cierto contenido noticioso. El objetivo es indagar las disposiciones y preferencias de consumo informativo de estudiantes de periodismo. Para ello, se aplicó un sondeo de opinión a estudiantes de segundo año de dos universidades privadas de la Región Metropolitana de Chile como muestra intencionada. La investigación sugiere que existen habilidades digitales generalizadas en los estudiantes con énfasis distintos al informarse, es decir, esquemas de percepción que podrían generar distinciones entre preferencias informativas y verificación de la información recibida según el género y la universidad en la que estudian. Además, un ejercicio en línea realizado posteriormente arrojó que, pese a la prevalencia de habilidades digitales, sus prácticas informativas distan de una valoración noticiosa basada en métodos de comprobación.

Abstract Since some decades ago, the convergence of media through a screen, the digitalization of communicative processes and the emergence of new informational practices reconfigure the journalism exercise and formation. This article shows the results of exploratory research around how journalism students get informed on current events and how they disfavor a certain type of news content. The main goal is to inquire about the disposition and preferences of information consumption in journalism students. For that, an opinion poll was performed to students of two private universities in the Metropolitan Region of Chile as an intentional sample. The research suggests that there are some generalized digital abilities among the students with different emphasis for informing themselves, i.e. perception schemes that might generate distinctions between informational preferences and verification of the information received according to their gender and university. Furthermore, an online exercise performed afterward, showed that despite the prevalence of digital abilities, their information practices are far from a newsworthy assessment based on checking methods.

Este artigo mostra os resultados de um estudo exploratório sobre como os estudantes de Jornalismo se informam na atualidade e selecionam as notícias. O objetivo é questionar as disposições e as preferências de consumo informativo de estudantes de Jornalismo. Para isso, foi aplicada pesquisa de opinião a estudantes do segundo ano de duas universidades particulares da Região Metropolitana do Chile como amostra intencional. Esta pesquisa sugere que haja habilidades digitais generalizadas nos estudantes com ênfases diferentes ao se informarem, isto é, esquemas de percepção que poderiam gerar distinções entre preferências informativas e verificação da informação recebida segundo o gênero e a universidade em que estudam. Além disso, o exercício on-line realizado posteriormente demonstrou que, embora haja prevalência de habilidades digitais, suas práticas informativas se baseiam em uma avaliação da notícia baseada em métodos de comprovação.

Resumen La encefalitis letárgica de von Economo es un trastorno neuropsiquiátrico de posible origen autoinmunitario, en el cual se afectan los ganglios basales. Esta reacción puede ocurrir luego de una infección aguda por diversos agentes virales o bacterianos. Dado que aparece cuando ya se ha resuelto el cuadro agudo, se ha propuesto el mecanismo del mimetismo molecular para explicar la lesión autoinmunitaria. Se han reportado diversos casos a lo largo del tiempo, pero fue con la pandemia de influenza de 1918, conocida como la gripe española, que la encefalitis letárgica alcanzó niveles de epidemia, con casos reportados hasta 1923 en diversos países. La pandemia de la gripe española se extendió a Colombia durante los últimos meses de 1918 y afectó varias ciudades, principalmente Bogotá, donde se reportó el mayor número de enfermos y muertos. Con este trabajo se busca rememorar, cien años después, el ingreso de la gripe española a nuestro país y sus principales complicaciones, entre las que se describieron algunos casos de encefalitis letárgica.

Abstract Von Economo’s encephalitis is a neuropsychiatric disorder of possible autoimmune origin, which affects basal ganglia. This reaction may occur secondary to infection by different viral or bacterial agents. Given that it appears after the acute episode has disappeared, molecular mimetism has been proposed to explain the autoimmune lesion. Several cases have been reported through time, but it was with the 1918 flu pandemic, known as the Spanish flu, that lethargic encephalitis reached epidemic levels with cases reported until 1923 in various countries. The Spanish flu pandemic appeared in Colombia at the end of 1918 in several cities but it affected especially Bogotá where the highest number of patients and deaths was reported. Our purpose with the present work was to commemorate the arrival of the Spanish flu to our country after one hundred years, as well as to reflect on its main complications, which included some lethargic encepahilitis cases.

Abstract: Science teachers are currently being called to teach using Big Ideas of Science Education, in order to integrate scientific knowledge that would be otherwise fragmented, to reduce the great amount of content planned for one school-year and allow teacher autonomy through the flexibility of the construct. This research aims to, through a dialogue between the main characters of this story, to describe the conceptualizations in both discourse and praxis of three teachers that use Big Ideas in Science Education in three schools in Valparaiso, Chile. We decided that the four main characters would tell the story, since the idea is not only to discuss the concept of “Big Ideas”, but also to illustrate the flexibility of this approach in praxis, and the common points of the experience for the three teachers in different schools.

Resumen: Actualmente, los profesores de Ciencias son llamados a enseñar con las Grandes Ideas de la Ciencia como una forma de integrar y agrupar conocimiento científico que de otra forma se mostraría fragmentado, reducir la gran cantidad de contenido que se supone para un año escolar y permitir autonomía por la flexibilidad del constructo. En esta investigación pretendemos, por medio de un diálogo narrado entre los protagonistas de esta historia, describir las conceptualizaciones en discurso y práctica de tres docentes enseñando Grandes Ideas de la Ciencia en tres escuelas de la región de Valparaíso, Chile. Decidimos contar esta historia entre los cuatro actores involucrados para poder, no solo discutir el concepto de “gran idea”, sino que también ilustrar la flexibilidad de este acercamiento en la práctica y la experiencia de docentes que, a pesar de enseñar en diferentes lugares, tienen puntos en común.

RESUMO Raciona l: A gastrectomia é o tratamento principal para o câncer de junção esofagogástrica (EGJ) e Siewert tipo II-III. Ela está associada à morbidade significativa. As taxas de morbidade total variam entre os diferentes estudos e poucos avaliaram a morbidade pós-operatória de acordo com a gravidade da complicação. Objetivo: Identificar os preditores de morbidade pós-operatória grave. Métodos: Este foi um estudo de coorte retrospectivo de um banco de dados prospectivo. Foram incluídos pacientes tratados com gastrectomia para câncer gástrico ou EGJ em um único centro. A morbidade severa foi definida como escore de Clavien-Dindo ≥3. Análise multivariada foi realizada para identificar preditores de morbidade grave. Resultados: Duzentos e oitenta e nove gastrectomias foram realizadas (67% homens, mediana de idade: 65 anos). A localização do tumor foi EGJ em 14%, o terço superior do estômago em 30%, o terço médio em 26% e o terço inferior em 28%. Em 196 (67%), foi realizada gastrectomia total com dissecção de linfonodos D2 em 85%. Duzentos e onze pacientes (79%) foram submetidos à gastrectomia aberta. O estado T foi T1 em 23% e T3/T4 em 68%. A mortalidade pós-operatória foi de 2,4% e a taxa de morbidade foi de 41%. A morbidade severa foi de 11% e foi representada principalmente por fístula esofagojejunal (2,4%), fístula duodenal (2,1%) e complicações respiratórias (2%). Na análise multivariada, a localização do EGJ e os tumores T3/T4 foram associados com maior morbidade pós-operatória grave. Conclusão: Morbidade pós-operatória severa após gastrectomia foi de 11%. A localização do tumor na junção esofagogástrica e o estado T3/T4 são fatores de risco para a morbidade pós-operatória grave.

ABSTRACT Background: Gastrectomy is the main treatment for gastric and Siewert type II-III esophagogastric junction (EGJ) cancer. This surgery is associated with significant morbidity. Total morbidity rates vary across different studies and few have evaluated postoperative morbidity according to complication severity. Aim: To identify the predictors of severe postoperative morbidity. Methods: This was a retrospective cohort study from a prospective database. We included patients treated with gastrectomy for gastric or EGJ cancers between January 2012 and December 2016 at a single center. Severe morbidity was defined as Clavien-Dindo score ≥3. A multivariate analysis was performed to identify predictors of severe morbidity. Results: Two hundred and eighty-nine gastrectomies were performed (67% males, median age: 65 years). Tumor location was EGJ in 14%, upper third of the stomach in 30%, middle third in 26%, and lower third in 28%. In 196 (67%), a total gastrectomy was performed with a D2 lymph node dissection in 85%. Two hundred and eleven patients (79%) underwent an open gastrectomy. T status was T1 in 23% and T3/T4 in 68%. Postoperative mortality was 2.4% and morbidity rate was 41%. Severe morbidity was 11% and was mainly represented by esophagojejunostomy leak (2.4%), duodenal stump leak (2.1%), and respiratory complications (2%). On multivariate analysis, EGJ location and T3/T4 tumors were associated with a higher rate of severe postoperative morbidity. Conclusion: Severe postoperative morbidity after gastrectomy was 11%. Esophagogastric junction tumor location and T3/T4 status are risk factors for severe postoperative morbidity.

Resumen La diabetes mellitus es una enfermedad de alta prevalência, así como también lo son sus complicaciones agudas. Una de ellas es el estado hiperosmolar no cetósico que raramente se asocia con alteraciones involuntarias del movimiento. Sin embargo, existe una condición que asocia alteraciones glucémicas con desórdenes del movimiento, denominado síndrome de corea hiperglicemia y ganglios basales, de la cual presentamos un caso y hacemos revisión de la literatura.

Abstract Diabetes mellitus is a disease of high prevalence, as well as its acute complications. One of them is the nonketotic hyperosmolar state that is rarely associated with involuntary changes in movement. However, there is a condition that associates glycemic alterations with movement disorders, called chorea hyperglycemia basal ganglia syndrome, of which we present a case and review the literature.

ABSTRACT In Chile, the Eucalyptus nitens (H. Deane & Maiden) Maiden × E. globulus Labill. hybrid presents the highest production potential due to its desirable characteristics for the production of cellulose. Nevertheless, its low ability to rooting complicates the clonal propagation in nurseries, with the need for new alternatives to increase rooting. The objective of this research was to evaluate the effect of rhizobacteria in the adventitious rooting of mini-cuttings of two hybrid E. nitens × E. globulus clones, wherein 106 rhizospheric bacterial isolates from five species and hybrids of Eucalyptus spp. were used. The mini-cuttings were treated at the base with a 20 mL liquid suspension of rhizobacterial strains. In addition, cultured bacteria were applied by manual sprinklers in the rooting substrate. In the first trial, 38% of rhizobacteria increased significantly rooting of X-64 clone mini-cuttings. Of these, in a second trial, 50% of rhizobacteria maintained their effect in promoting the rooting in two clones, and in the third trial among the 20 strains evaluated, 10 strains increased rooting in both clones. The rhizobacteria that had the most consistent effect in the rooting increase of the mini-cuttings were species of Bacillus and Pseudomonas sp., as well as the genera Chryseobacterium, Mucilaginibacter and Rhodococcus sp., with these results, it is concluded that 10 rhizobacterial isolates have increased the adventitious rooting of minicuttings of two hybrid clones of E. nitens × E. globulus, and these inoculants could be used in periods of underperformance of minicuttings, in order to optimize their performance.

International guidelines include resistance exercise as part of osteoporosis treatment, although there is no clear agreement on exercise prescription. The aim of this study was to assess methodological quality of clinical guidelines that included exercise as a therapeutic intervention for osteoporosis, in order to establish the recommendations with the best level of evidence. A systematized review on clinical guidelines for osteoporosis published between 2010 and 2014 was performed. Each guide was assessed by 4 blinded reviewer experts on osteoporosis rehabilitation. Guidelines scored 4.5 or more were selected for data extraction. Intra-class concordance coefficient was obtained for overall guideline assessment. Three guidelines fulfilled our inclusion criteria. After Appraisal of Guidelines for Research & Evaluation II (AGREE-II) assessment, 2 obtained 4.5 or more AGREE-II score. Only exercise recommendations were included. Future clinical guidelines development and updates must enhance adequate methodological quality, considering age, comorbidities and functional assessment in exercise prescription for osteoporosis treatment.

Las guías de práctica clínica internacional comprenden ejercicios de resistencia como parte del tratamiento de osteoporosis, aunque no existe un consenso en la prescripción de ejercicio. El objetivo del presente estudio fue evaluar la calidad metodológica de guías de práctica clínica actuales que incluyeran al ejercicio como una intervención terapéutica para el tratamiento de osteoporosis, para establecer recomendaciones con mejor nivel de evidencia. Para ello, se realizó una revisión sistemática de guías de práctica clínica para osteoporosis publicadas entre 2010 y 2014. Cada guía fue evaluada en forma cegada por cuatro revisores expertos en rehabilitación de osteoporosis. Las guías con una puntuación igual o mayor a 4.5 fueron seleccionadas para la extracción de datos. Se calculó el coeficiente de concordancia intra-clase para la evaluación global de la guía clínica. Los resultados señalan que tres guías de práctica clínica cumplieron los criterios de inclusión. Posterior a la evaluación con el sistema Appraisal of Guidelines for Research & Evaluation II (AGREE-II, por sus siglas en inglés), dos guías obtuvieron un puntaje de 4.5 o mayor. Únicamente se incluyeron las recomendaciones sobre ejercicio. Se concluye que el desarrollo y actualización de guías de práctica clínica debe mejorar la calidad metodológica, considerando edad, comorbilidades y evaluación funcional de los pacientes para la prescripción de ejercicio en el tratamiento de osteoporosis.

Background: The laparoscopic approach for the treatment of gastric tumors has many advantages. Aim: To evaluate the results of a laparoscopic gastrectomy program developed in a public hospital. Patients and Methods: Retrospective review of epidemiological, perioperative and follow-up data of patients who were treated with a laparoscopic gastrectomy due to gastric tumors between 2006 and 2013. A totally laparoscopic technique was used for all cases. Complications were evaluated according to the Clavien-Dindo classification. Results: Fifty one patients, aged 65 (36-85) years, underwent a laparoscopic gastrectomy. In 22 patients a total gastrectomy was performed. Conversion rate to open surgery was 8%. Operative time was 330 (90-500) min and bleeding was 200 (20-500) ml. Median hospital stay was 7 (3-37) days. Postoperative morbidity was present in 17 (33%) patients, 3 (6%) patients had complications grade 3 or higher and one patient died (1.9%). Tumor pathology was adenocarcinoma in 39 patients. A complete resection was achieved in 97%. Twenty nine patients (74%) with gastric adenocarcinoma had early gastric cancer and 84% of patients were in stage one. Median lymph node count was 24. Median follow-up was 26 (1-91) months. There was no cancer related mortality among patients subjected to a curative resection. Overall survival for patients with adenocarcinoma was 92% at 3 years. Conclusions: This study supports the feasibility and safety of a laparoscopic gastrectomy program in a public hospital; with low morbidity, adequate lymph node dissection and long-term survival. This approach must be considered an option for selected patients with gastric cancer.
