Desplazamiento cotidiano de estudiantes entre comunas de Chile: evidencia y recomendaciones de política para la nueva institucionalidad de la Educación Pública

Donoso-Diaz, S (Donoso-Diaz, Sebastian) ; Arias-Rojas, O (Arias-Rojas, Oscar). Univ Talca, Talca, Chile.A key feature of the Chilean school system is the discrimination in educational provision, showing a strong association between learning outcomes, on the one hand, and cultural capital and income of households, on the other. This discrimination forces families to seek educational institutions according to their expectations, generating mobility of students from their communities of origin to other communities. The analysis of the Chilean survey of households in 2006 allowed to quantify this phenomenon (student commuting), and demonstrated the existence of patterns associated with the dynamics of settlement of the population along the country: low mobility in the end regions, intermediate in the central regions of the country, and high in the Metropolitan Region of Santiago. According to these results, we discuss policy recommendations essential to incorporate the territorial dimension in the design of the new institutions of public education in Chile

Determinants of Teacher Quality: Pedagogical Excellence Accreditation Program

Garcia, LY (Garcia, Leidy Y.); Cerda, AA (Cerda, Arcadio A.); Donoso-Diaz, S (Donoso-Diaz, Sebastian)Teachers at primary and secondary schools constitute a hey factor in the educative process and learning results of their students. Given the constitutional mandate that defines the slate's responsibility to provide high-quality public education, it must attract. retain and motivate "good" teachers through diverse mechanisms and incentives, and in the Chilean case it must generate efficient mechanisms to evaluate their teaching performance. The Program to Reward Pedagogical Excellence (AEP from its Spanish acronym) conic about in this framework as a mechanism lot evaluation and incentives, because it aims to evaluate significant aspects of the quality of teachers, awarding bonuses to the roost outstanding. Given the importance of educational quality in establishments subsidized by the state (both municipal and private) for the development of the country and society, this work aims to determine the characteristics of teachers who have obtained ALP quality accreditation, through a conditional probit model using data from a longitudinal Teaching Survey (ELD from its Spanish acronym), while also calculating the probability of participating in this program. We conclude that the factors that explain the probability of being accredited are: experience, the family's socioeconomic condition. the mother's educational level, the teacher's educational level training and internships, quality of health conditions, vocation and quality of the AEP program, which have significant hut reduced effect

Septic shock in pediatrics I. Current approach in diagnosis and therapeutics

Indexación: Web of Science; Scielo.El shock séptico es una de las principales causas de mortalidad infantil a nivel mundial y representa una compleja y progresiva vía inflamatoria secundaria a una enfermedad infecciosa, la cual origina disfunción cardiovascular aguda, no necesariamente hipotensión arterial, condicionando disoxia tisular y eventualmente falla celular y orgánica. Los paquetes de medidas de resucitación propuestos enfatizan el reconocimiento clínico y un tratamiento precoz. Estas intervenciones se basan en la pronta y agresiva resucitación con fluidos intravenosos para una adecuada perfusión tisular, administración de antibióticos, remoción del foco infeccioso y el uso de drogas vasoactivas en caso de ser necesario. La terapia debe evaluarse permanentemente según la normalización de metas clínicas y de laboratorio. En la presente publicación se actualiza el conocimiento de las características epidemiológicas y fisiopatológicas de la sepsis, una puesta al día en definiciones operacionales, campañas internacionales y referentes a las iniciativas propuestas para disminuir su morbimortalidad. Se aborda el enfoque terapéutico inicial en el servicio de urgencia. El objetivo de este artículo es dar a conocer el estado actual del conocimiento en el diagnóstico y tratamiento del paciente con shock séptico especialmente en su fase inicial previo al ingreso a UCI.Septic shock is a major cause of infant mortality worldwide and represents the progressive underlying inflammatory pathway secondary to an infectious disease, which causes acute cardiovascular dysfunction, not necessarily hypotension, tissue dysoxia and eventually cellular and organ failure. Standard resuscitative measures emphasize clinical recognition and early treatment. These interventions are based on early and aggressive resuscitation with intravenous fluids to optimize tissue perfusion, antibiotics, removal of the source of infection and the use of vasoactive drugs if necessary. Therapy should be permanently evaluated according to the standardized laboratory and clinical targets. This publication is an update on the epidemiology and pathophysiology of sepsis, operational definitions, current international campaigns and initiatives concerning proposals to decrease the morbidity and mortality of this condition. It also addresses initial therapeutic approaches in the emergency room. The aim of this study is to present the current state of knowledge in the diagnosis and treatment of patients with septic shock especially in the initial phase before admissions to intensive care units.http://ref.scielo.org/sbjrb

Septic shock in ICU: Advanced therapeutics, immunoparalysis and genomics. State of the art

Indexación: Web of Science; Scielo.En las últimas décadas, se han incorporado nuevos y trascendentes conceptos para el tratamiento avanzado del paciente en shock séptico. Se debe considerar el uso de terapia inmune en grupos seleccionados de pacientes. Las terapias de sustitución renal de carácter continuo sonbien toleradas y su empleo precoz evita sobrecargas de fluidos. El uso de hemofiltración de alto volumen puede jugar un papel en el paciente séptico hiperdinámico. La plasmaféresis es útil en el paciente con disfunción multiorgánica. El empleo de soporte extracorpóreo se debe considerar en quienes presentan shock séptico refractario. La inmunoparálisis se ha asociado con infecciones nosocomiales y mortalidad tardía. La información obtenida de los marcadores genéticos puede permitir la búsqueda de una medicina basada en la genómica.New and important concepts have emerged for the advanced management of the child with septic shock in the recent decades. Attending physicians in the Pediatric intensive care unit must be fully aware of them to improve patient care in the critical care unit. It should be considered the use of immune therapy only in selected groups of patients. Continuous renal replacement therapies are well tolerated and their early use prevents deleterious fluid overload. Removal of inflammatory mediators by using high volume hemofiltration may play a role in hyperdynamic septic patients. The use of plasmapheresis is recommended in patients with thrombocytopenia-associated multiple organ failure. Extracorporeal support use should be considered in those with refractory septic shock despite goals directed therapy. The immunoparalysis has been associated with nosocomial infections and late mortality. The information from genetic markers may allow early intervention and preventive genomics-based medicine.http://ref.scielo.org/g8m9m

Septic shock in intensive care units. Current focus on treatment

Indexación: Web of Science; Scielo.Los pilares terapéuticos del niño con shock séptico se mantienen en el tiempo, sin embargo, se han incorporado nuevos conceptos, siendo importante que el pediatra y el intensivista tengan conocimiento a cabalidad de ellos. La reanimación con fluidos es una intervención fundamental, no obstante, aún no se ha establecido un tipo de fluido ideal, presentando cada uno limitaciones específicas, no existiendo evidencia sobre la superioridad de un tipo de fluido. Si a pesar de una adecuada resucitación con fluidos persiste el shock, el inicio de inótropos y/o vasopresores está indicado. En caso de refractariedad al uso de vasopresores, nuevos fármacos vasoactivos pueden ser empleados y el uso de hidrocortisona debe considerarse en niños con sospecha de insuficiencia suprarrenal. Existe controversia respecto a la transfusión de glóbulos rojos o el nivel óptimo de glucemia, no existiendo consenso en el valor umbral para el uso de estos hemocomponentes o el inicio de insulina, respectivamente. Asimismo, la utilización de la hemofiltración de alto volumen (HFAV)aún permanece controversial, requiriendo mayores estudios para su recomendación en forma rutinaria en el curso de un shock séptico refractario. El soporte nutricional es primordial, ya que la desnutrición es una grave complicación que debe ser prevenida y tratada adecuadamente. El objetivo de la presente revisión es entregar una actualización en los más recientes avances en tratamiento del shock séptico en la población pediátrica.Essential therapeutic principles in children with septic shock persist over time, although some new concepts have been recently incorporated, and fully awareness of pediatricians and intensivists is essential. Fluid resuscitation is a fundamental intervention, but the kind of ideal fluid has not been established yet, as each of these interventions has specific limitations and there is no evidence supportive of the superiority of one type of fluid. Should septic shock persists despite adequate fluid resuscitation, the use of inotropic medication and/or vasopressors is indicated. New vasoactive drugs can be used in refractory septic shock caused by vasopressors, and the use of hydrocortisone should be considered in children with suspected adrenal insufficiency, as it reduces the need for vasopressors. The indications for red blood cells transfusion or the optimal level of glycemia are still controversial, with no consensus on the threshold value for the use of these blood products or the initiation of insulin administration, respectively. Likewise, the use of high-volume hemofiltration is a controversial issue and further study is needed on the routine recommendation in the course of septic shock. Nutritional support is crucial, as malnutrition is a serious complication that should be properly prevented and treated. The aim of this paper is to provide update on the most recent advances as concerns the treatment of septic shock in the pediatric population.http://ref.scielo.org/79wr6

Septic shock in pediatrics II. Current concepts in diagnosis and treatment

Indexación: Web of Science; Scielo.Aunque los principios básicos para el diagnóstico y los pilares terapéuticos del niño con shock séptico se mantienen en el tiempo, es innegable que en las últimas décadas se han incorporado nuevos y trascendentes conceptos, siendo importante que el médico tratante en el Servicio de Urgencia tenga conocimiento a cabalidad de ellos. En la segunda parte de esta actualización se discuten las similitudes y diferencias entre la población infantil y adulta, la utilidad de las metas de reanimación metabólicas, como también el enfoque terapéutico inicial en el paciente séptico. Los conceptos más importantes revisados se refieren a las diferencias entre el niño y adulto con shock séptico, especialmente en la fisiopatología, clínica y tratamiento. Se recalca la importancia de expansión de la volemia y el uso de drogas vasoactivas si no hay respuesta a fluidos de reanimación. El manejo terapéutico debe estar orientado a la búsqueda de la normalización de metas macrohemodinámicas y de perfusión sistémica. Se deben evitar los errores más frecuentes de observar en el tratamiento inicial del paciente séptico. Esta entidad presenta una elevada incidencia y mortalidad, por lo cual el manejo precoz y agresivo es de máxima importancia en pediatría.Although the basic concepts of diagnosis and therapy of the child with septic shock have remained similar over time, it is undeniable that in recent decades, new and important concepts have been added, and any treating physician either at the Emergency Department or Intensive Care Unit should be fully aware of them. This second part discusses the similarities and differences between pediatric and adult populations, the utility of metabolic resuscitation goals, as well as the initial therapeutic approach in septic patients. The most important concepts of this work make reference to the differences between children and adults with septic shock, specifically regarding to pathophysiology, clinical presentation and treatment. Volume expansion and vasoactive drugs are crucial if there is no response to fluid resuscitation. The therapeutic management should focus on finding the normalization of macrohemodynamic and systemic perfusion targets. Common observation mistakes in the initial treatment of septic patients should be avoided. This condition has a high incidence and mortality rate; therefore an early and aggressive treatment is essential.http://ref.scielo.org/cc6t3
