Critical analysis of the definition of severe dengue, based on the Ecuador outbreak in 2012  [PDF]
Natalia Romero Sandoval, Pablo Lozano, Jacqueline Cevallos, Virginia Ruiz, Miguel Martín
Open Journal of Epidemiology (OJEpi) , 2014, DOI: 10.4236/ojepi.2014.41007
Abstract: Of the 238 cases reported to the Ecuador Health Authorities in 2012 as severe dengue, only 53.3% met diagnostic criteria. The definition of severe dengue should be based on more precise criteria. Information about compliance with criteria should be fed back to local levels.

Abstract: objective: among the most severe complications caused by the influenza a virus h1n1 pandemic is the acute respiratory distress syndrome (ards). the main objective of this study was to assess mortality after applying a strict protocol of ventilatory management and to describe the clinical characteristics of the patients. design: a prospective cohort study. setting: intensive care unit (icu) of the hospital enrique garcés of the city of quito. patients: patients admitted to the icu with a diagnosis of severe pneumonia, ards, and high suspicion of influenza a h1n1. primary variables of interest: demographic variables, severity, diagnostic scores of community-acquired pneumonia, ventilator management protocol and mortality at 28 days, as principal effect of the study, were collected. results: 24 patients were studied, 100% with a diagnosis of ards, mean age 41.1 (±14.8). severe viral pneumonia predominated in these patients, mean apache was 18, average pao2/fio2 on admission was 74.9, 100% had multisystemic involvement. a total of 91.3% received oseltamivir 150mg w/12h for 14 days, the mean time between onset of symptoms and antiviral administration was 6.74 days. intra-icu mortality was 16.6%, and 28 days was 16.6%. conclusions: after applying a strict management protocol for ventilatory management, mortality in this patient group was 16.6. we also stress that obesity and early renal failure were independent risk factors for mortality.

Abstract: Objetivo: La pandemia causada por el virus de la influenza A H1N1, entre sus complicaciones más severas esta el síndrome de distrés respiratorio agudo. El objetivo principal de esta trabajo fue evaluar la mortalidad luego de aplicar un protocolo estricto de manejo ventilatorio y describir las características clínicas de los pacientes. Dise o: Es un estudio de cohorte prospectivo. ámbito: UCI del Hospital Enrique Garcés del la Cuidad de Quito. Pacientes: Pacientes ingresados a la UCI con diagnóstico de neumonía grave, síndrome de distrés respiratorio agudo, y alta sospecha de influenza A H1N1. Principales variables de interés: Se recogieron variables demográficas, de gravedad, scores diagnósticos de neumonía adquirida en la comunidad, protocolo de manejo ventilatorio y mortalidad a los 28 días, como efecto principal del estudio. Resultados: Se estudiaron 24 pacientes, el 100% con diagnóstico de síndrome de distrés respiratorio agudo, media de edad de 41,1 (±14,8). La neumonía viral grave predominó en estos pacientes, la media de APACHE fue 18, la media de PaO2/FiO2 al ingreso fue 74,9, el 100% presentaron compromiso multisistémico. El 91,3% recibieron oseltamivir 150mg c/ 12h durante 14 días, la media entre inicio de síntomas y administración de antiviral fue 6,74 días. La mortalidad intra UCI fue del 16,6% y a los 28 días fue de 16,6%. Conclusiones: Después de la aplicar un protocolo de manejo estricto del manejo ventilatorio, la mortalidad de este grupo de pacientes fue del 16,6%, además destacamos que la obesidad y la falla renal temprana fueron factores de riesgo independiente para mortalidad.

El sector informal urbano del Ecuador: Una visión de su magnitud actual y la particular situación de la mujer en éste

Abstract: RESUMEN: El desempleo y el subempleo, pero de manera particular el segundo, han sido, son y serán (al menos en el mediano plazo) dos de los problemas socio-económicos de mayor impacto, complejo tratamiento y difícil solución que tiene el Ecuador y otros países con similar estructura socio-económica. Aunque el subempleo (conocido también como Sector Informal), llega a sus niveles más altos (medido a través del porcentaje de la PEA que está inmersa en él), en los tiempos de estancamiento e inestabilidad económica su configuración y evolución depende también, en una proporción significativa, de factores estructurales. ABSTRACT: The unemployment and the underemployment, spetially the second one, are among the problems of the ecuadorian society, that have the highest impact in the population, complex treatment and complicated solution. Although the underemployment, called too "Informal Sector" of the economy, gets its highest levels (measured by the percentaje of the "Econonically Active Population" wich is underemployed), in the years when the country has have recession and economic instability, its configuration and evolution depends on structural motivations, in an important proportion.

The Pedagogy of Visual Discourse: An Analytical Approach to Teaching and Evaluating the Rhetorical Image  [PDF]
Jacqueline Irwin
Art and Design Review (ADR) , 2014, DOI: 10.4236/adr.2014.22003
Abstract:

As the area of visual rhetoric develops and evolves, the approaches that critics take in evaluating images must be scrutinized for the overall exploration of the discipline. Incorporating areas of analytical criticism from rhetoric to aesthetics to design should be combined to create the best possible way of evaluating imagery. By expanding on the traditional analytical approach to rhetorical criticism, this paper explores how the additional understanding of aesthetic and design theory will help the critic to reach a fuller understanding of the image. The twelve major principles of design being line, shape and form, space, texture, value, color, repetition, variety, rhythm, balance, emphasis, and economy are combined to create the strategy of the visual aesthetic that works to compliment the existing rhetorical strategies. The more complete understanding of how visuals are created and how people interpret them will allow for a more complete development of the visual rhetorical approach to communication.

Carbon dioxide removal device: how long is long enough?

Critical Care , 2007, DOI: 10.1186/cc5130
Abstract: In 1969 Kolobow and coworkers [2] described use of VVCO2R in healthy sheep for 1 week, and they later demonstrated improved survival in injured sheep [3]. Clinical trials, however, failed to show improved outcomes [4]. Arteriovenous carbon dioxide removal (AVCO2R), as a simple arteriovenous shunt, eliminates several circuit components. AVCO2R removes near total carbon dioxide production with only 1 l/min (approximately 15% of cardiac output) blood flow and appears to be effective in acute respiratory distress disorder (ARDS), as shown in prospective randomized large animal and preliminary clinical trials.Our sheep model of severe ARDS is based on a third degree burn to 40% of the total body surface area and 48-breath smoke inhalation injury [5]. Because the median duration of AVCO2R treatment for ARDS is 4.8 days, our model allows comparison of ventilatory techniques over 5 days to evaluate pathophysiology and outcomes [6].Based on the experience with carbon dioxide removal, two major concerns arise. First, the circuit blood flow employed by Livigni and coworkers is only 5% of the cardiac output, which was inadequate to achieve normalization of arterial carbon dioxide pressure (PaCO2). Use of larger cannulae (12 to 15 Fr) would allow flows up to 1 l/min. Second, studies of such short duration in healthy animals have limited clinical relevance [7].We wonder whether the methods employed by Livigni and coworkers would have an impact on survival in 5-day large animal studies of lung injury or in clinical application.Sergio Livigni, Marco Vergano and Guido Bertolini.In response to the concerns raised by Cevallos and Zwischenberger, we should like to stress the following points.First, since the 1970s many things have changed both in research methodology and in clinical practice. From a research perspective, clear evidence of the efficacy/futility of techniques (in this case arteriovenous and venovenous) now requires much greater effort in terms of patient numbers (in some
