Abstract

Abstract Background During the COVID-19 pandemic, a great number of patients required Mechanical Ventilation (MV). Tracheostomy is the preferred procedure when difficult weaning is presented. Surgical techniques available for performing tracheostomy are open and percutaneous, with contradictory reports on the right choice. This paper aims to describe the clinical results after performing a tracheostomy in patients with COVID-19, regarding both surgical techniques. Methods An observational, analytical study of a retrospective cohort was designed. All patients admitted to the Hospital Universitario Mayor Méderi, between March 2020 and April 2021 who presented COVID-19 requiring MV and who underwent tracheostomy were reviewed. Open versus percutaneous tracheostomy groups were compared and the primary outcome evaluated was in-hospital mortality. Results A total of 113 patients were included in the final analysis. The median age was 66.0 (IQR: 57.2 – 72.0) years old and 77 (68.14%) were male. Open tracheostomy was performed in 64.6% (n = 73) of the patients and percutaneous tracheostomy in 35.4% (n = 40) with an in-hospital mortality of 65.7% (n = 48) and 25% (n = 10), respectively (p

Abstract

Los cultivares de pimentón (Capsicum annuum L.) cultivados en Colombia provienen de países con zonas templadas, lo que limita su producción en las condiciones climáticas y agroecológicas del país, al no alcanzar su adaptabilidad y potencial de rendimiento, debido a los factores que afectan la expresión de los genes. En Colombia el 95% del pimentón se siembra a campo abierto, sin embargo, los agricultores buscan alternativas para mejorar el rendimiento, como la agricultura protegida con techo plástico y ventilación natural. El objetivo de la investigación fue evaluar el comportamiento agronómico de cuatro cultivares de pimentón (BG2, Cuadrado rojo, Cacique y Nathalie) producidos en tres ambientes: campo abierto en el 2014 y protegido en dos ciclos (2013 y 2014). Los ensayos se establecieron en el Centro de Investigación La Selva (AGROSAVIA), Rionegro-Antioquia (Colombia), con experimentos multilocacionales en un diseño de bloques completos al azar. Se midieron las variables rendimiento, número, longitud y diámetro ecuatorial de frutos, clasif icándolos por categorías; también se determinó la incidencia de plagas y enfermedades. No se encontraron diferencias estadísticas signif icativas en el rendimiento obtenido en los tres ambientes evaluados. El efecto genético del cultivar fue más determinante que el efecto ambiente en las variables del rendimiento. Los cultivares más rendidores fueron Cacique y Nathalie, mientras que BG2 y Cuadrado rojo presentaron los mayores descartes de frutos en condiciones protegidas. La incidencia de plagas y enfermedades fue irregular, la mayor ocurrencia se presentó en condiciones protegidas, pero sin tener relación directa con los cultivares.

Abstract

Introducción. En el cultivo de pimentón se han recomendado las podas para mejorar la intercepción de luz, aumentar el cuajado y la calidad de los frutos. Objetivo. Evaluar el efecto de las podas sobre los componentes de rendimiento de dos híbridos de pimentón establecidos en dos ambientes: campo abierto y campo protegido bajo techo plástico con ventilación natural. Materiales y métodos. Se realizaron dos ensayos en el Centro Investigación La Selva de la Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA), Rionegro, Antioquia, Colombia. Se evaluaron dos híbridos de pimentón tipo bloque en dos ambientes: campo abierto (en el ciclo 2013-2014) y campo protegido bajo techo plástico (en los ciclos 2013-2014, 2014-2015) y tres sistemas de podas de formación: dos tallos, tres tallos y sin podar. Para el primer ensayo se empleó un diseño de bloques completos al azar con seis tratamientos (dos híbridos y tres sistemas de poda) y cinco repeticiones. Para el segundo se establecieron los mismos tratamientos solo bajo el ambiente protegido, en un diseño de bloques completos al azar. Resultados. Hubo diferencias estadísticas para rendimiento total en el sistema sin podar en ambos ensayos. En el ambiente protegido–2013 los híbridos alcanzaron una producción media de 36,7 t ha-1, el sistema sin podas fue el más rendidor (promedio 49,7 t ha-1). A campo abierto el rendimiento fue de 23,6 t ha-1. Los rendimientos totales obtenidos bajo el ambiente protegido-2014 (36,2 t ha-1), igualaron al obtenido en 2013 y superaron estadísticamente los de campo abierto. Conclusión. Las plantas sin podar mostraron los mejores rendimientos en ambos ensayos. En algunas variables se presentaron diferencias entre los ambientes, los híbridos de pimentón y su interacción. Se deben realizar estudios adicionales para determinar si el ambiente protegido es adecuado para el desarrollo de los híbridos.

Abstract

Introduction Severe asthma is a rare disease in children, for which three biologicals, anti-immunoglobulin E, anti-interleukin-5 and anti-IL4RA antibodies, are available in European countries. While global guidelines exist on who should receive biologicals, knowledge is lacking on how those guidelines are implemented in real life and which unmet needs exist in the field. In this survey, we aimed to investigate the status quo and identify open questions in biological therapy of childhood asthma across Europe. Methods Structured interviews regarding experience with biologicals, regulations on access to the different treatment options, drug selection, therapy success and discontinuation of therapy were performed. Content analysis was used to analyse data. Results We interviewed 37 experts from 25 European countries and Turkey and found a considerable range in the number of children treated with biologicals per centre. All participating countries provide public access to at least one biological. Most countries allow different medical disciplines to prescribe biologicals to children with asthma, and only a few restrict therapy to specialised centres. We observed significant variation in the time point at which treatment success is assessed, in therapy duration and in the success rate of discontinuation. Most participating centres intend to apply a personalised medicine approach in the future to match patients a priori to available biologicals. Conclusion Substantial differences exist in the management of childhood severe asthma across Europe, and the need for further studies on biomarkers supporting selection of biologicals, on criteria to assess therapy response and on how/when to end therapy in stable patients is evident.

Abstract

One of the causes of overusing compound and simple fertilizers in “Oriente Antioqueño” region is the low offer of research articles on fertilization in broccoli. Two experiments were carried out at municipality of Rionegro, Antioquia (Colombia). The first experiment was conducted in the second semester of 2013 in which two broccolis cultivars, Compact and De Cicco, were used. A randomized complete block design (RCBD) with four nitrogen doses (0, 50, 90 and 130 kg N ha-1) was arranged in a factorial 2 x 4, getting eight treatments. Using “San Cristobal” model in a RCBD design, Avenger and Legacy cultivars were grown in the second semester of 2014 including four levels of N, P2O5 and K2O as factors, arranging a total of 12 treatments in an incomplete factorial. Results of this experiment showed that in the first test, Compact cultivar reached a maximum production of 15.5 t ha-1 and De Cicco developed non-tradable inflorescences where a dose of 90 kg N ha-1 was applied, showing a low adaptation to this environmental conditions. In the second experiment, the relative growth height rates –stem diameter and yields- did not show significant statistical differences (P>0.05) regarding the treatments and cultivars evaluated. Avenger and Legacy got the highest yields, 19.0 and 12.2 t N ha-1 respectively, using doses of 60 kg N ha-1, 40 kg P2O5 ha-1 and 55 kg K2O ha-1.

Abstract

Some unappropriated techniques are found in bell pepper agricultural management. Those are: non-balancing nutritional profile among soil contribution, crop requirements and fertilizer efficiency, excessive use of composite sources and the lack of availability of studies on recommendations in different environments where this crop is grown. In order to mitigate the inadequate techniques in the agronomic management of bell pepper, an evaluation of four fertilization treatments under open field and protected conditions with plastic cover was conducted. Nathalie cultivar was grown during 2014-B and 2015-A at “Corporación Colombiana de Investigación Agropecuaria”, – CORPOICA research center, located in Llanogrande, township of Rionegro (Antioquia, Colombia). The treatments (T) evaluated were: T1: 250, 75, 180 and 90; T2: 170, 50, 120 and 60; T3, 100, 40, 80 and 40 and T4: 60, 25, 50 and 25 kg.ha-1 of N, P2O5, K2O and MgO, respectively. T2 and T4 correspond to crop requirements established by previous research. In addition, simple sources were used as follows: Urea, DAP, Potassium chloride and Magnesium sulphate, which were arranged in a split-plot design. For the relative crop growth rate (TCR) and yield variables, differences were shown under two evaluated conditions. In open field condition, the highest production and stem diameter were recorded; there were not differences among treatments. T3 is recommended because it showed similar yield to the other three ones. This Treatment allowed reestablishing and maintaining soil fertility levels, with a rational, efficient and low use of fertilizers, without generating contamination and salinity problems.

Abstract

This article presents the results of a pilot study about the implementation of informatics tools of social use HIUS (known as social software) perform on students of fourth grade on high school on a public school. We explored four dimensions: frequency of use, handling level, usage and type of interaction. The tools are grouped into 12 types. The population said they did not know/use many of the tools. We found that there is a high frequency of use and high skills in handling social networks, video sharing and chat services, while there is very little use and handling of tools like blogs and social bookmarking. The most commonly used mode was "chat/enjoy" followed by "to learn" and "to study". The use of tools comes from own accounts and in general they add and remove content more or less in the same proportion.

Abstract

Este ensayo busca señalar las diferencias de perspectiva que hay entre la economía institucional y la ciencia económica walrasiana, como parte de un intento por ilustrar la forma en que la economía institucional representa una alternativa, aunque incompleta, al enfoque convencional de la economía. La comparación entre las concepciones de individuo, el conocimiento, la eficiencia y el orden económico son las principales herramientas utilizadas para mostrar estas diferencias entre ambas perspectivas. Se señalan también algunas discusiones metodológicas derivadas de estas diferencias.
