Programa preventivo-educativo en niños escolares de Quilino, Córdoba

El docente universitario que trabaja en salud y como integrante de un equipo de salud debe transferir, difundir y poner en práctica una filosofía de la Prevención en relación con los aspectos sanitarios de la comunidad a través de la implementación de programas de salud y es en el ámbito escolar, donde educadores, alumnos y profesionales trabajan conjuntamente en actividades de Educación para la Salud y en la prevención de las enfermedades. Dentro de las acciones preventivas en el área de la salud bucal, las acciones preventivas-educativas, conjuntamente con su entorno socio-familiar tienen mayor impacto desde temprana edad, para la incorporación de las mismas. La finalidad es comparar el comportamiento de variables clínicas-odontológicas (CPOD, ceod e IHOS) después de la implementación de un Programa Educativo-Preventivo, sobre la salud bucal en escolares rurales.Se llevó a cabo la enseñanza de técnica de cepillado, aplicación de flúor profesional, talleres educativos-preventivos destinados a la comunidad educativa. Se realizaron dos controles anuales a los niños del Centro Educativo Manuel Belgrano de la localidad de Quilino, Córdoba. Se realizó el registro del estado de la salud bucal, índice ceod y CPOD, IHOS (Green y Vermillon).Relevando hábitos dietéticos, conocimientos previos y actitudes hacia la salud bucal. Luego de tres años de trabajo, con visitas cada seis meses, se observó la estabilización del componente caries, con un 46% ceod y 59% CPOD; una mejora en el IHOS; tanto docentes, padres y niños, demostraron un mayor conocimiento y apropiación de las medidas preventivas mediante jornadas de actividades grupales, manuales y creativas plasmando el aprendizaje realizado.Se concluye que la Educación es un instrumento de transformación social, toda acción educativa puede propiciar la reformulación de hábitos, la aceptación de nuevos valores, estimula la creatividad y el impacto en el mejoramiento de la Salud en el componente bucal.Palabras claves: Salud Bucal; Prevención;- Formación de Promotores

A Failure Detection Method for Gas Turbine Sensors Based on Arx, Neural Network and Fuzzy Logic Models

In a free energy market the reduction of operating costs becomes a primary goal and, in this context, energy producers require the availability of assistance systems, with a particular attention to maintenance periods and fault prevention. In order to accomplish this task, utilities need diagnostic systems able to describe plant components health state, analysing the measured data signals in real time. The present paper deals with the FDI (Fault Detection and Isolation) environment, focusing on the problem of sensor diagnostics. This work describes the development of a diagnosis system able to individuate and isolate faults of different entity occurring in gas turbine sensors, provided that the fault affects only one sensor at a time. The applied methodology is based on the gas path analysis using the technique of analytical redundancy, by means of three different kinds of black box simulators: ARX, Artificial Neural Network and Fuzzy Logic. The sensors control has been effected disposing in parallel the three above mentioned models, in order to reliably identify the monitored sensors faults. The diagnosis system has been implemented in the Matlab-Simulink environment and tested on a data series, coming from a single shaft gas turbine power plant supplied by Ansaldo Energia

Impact of Procedure Time on First Pass Effect in Mechanical Thrombectomy for Anterior Circulation Acute Ischemic Stroke

First pass effect (FPE) is a metric increasingly used to determine the success of mechanical thrombectomy (MT) procedures. However, few studies have investigated whether the duration of the procedure can modify the clinical benefit of FPE. We sought to determine whether FPE after MT for anterior circulation large vessel occlusion acute ischemic stroke is modified by procedural time (PT). A multicenter, international data set was retrospectively analyzed for anterior circulation large vessel occlusion acute ischemic stroke treated by MT who achieved excellent reperfusion (thrombolysis in cerebral infarction 2c/3). The primary outcome was good functional outcome defined by 90-day modified Rankin scale scores of 0-2. The primary study exposure was first pass success (FPS, 1 pass vs ≥2 passes) and the secondary exposure was PT. We fit-adjusted logistic regression models and used marginal effects to assess the interaction between PT (≤30 vs >30 minutes) and FPS, adjusting for potential confounders including time from stroke presentation. A total of 1310 patients had excellent reperfusion. These patients were divided into 2 cohorts based on PT: ≤30 minutes (777 patients, 59.3%) and >30 minutes (533 patients, 40.7%). Good functional outcome was observed in 658 patients (50.2%). The interaction term between FPS and PT was significant ( P = .018). Individuals with FPS in ≤30 minutes had 11.5% higher adjusted predicted probability of good outcome compared with those who required ≥2 passes (58.2% vs 46.7%, P = .001). However, there was no significant difference in the adjusted predicted probability of good outcome in individuals with PT >30 minutes. This relationship appeared identical in models with PT treated as a continuous variable. FPE is modified by PT, with the added clinical benefit lost in longer procedures greater than 30 minutes. A comprehensive metric for MT procedures, namely, FPE 30 , may better represent the ideal of fast, complete reperfusion with a single pass of a thrombectomy device

Abstract 153: First Pass Effect in Mechanical Thrombectomy for Anterior Circulation Acute Ischemic Stroke is Modified by Procedure Time: Proposal of a New Measure for Thrombectomy Procedures

Abstract only Objective: To determine whether first pass effect (FPE) after mechanical thrombectomy (MT) for anterior circulation large vessel occlusion acute ischemic stroke (LVO-AIS) is modified by procedural time (PT). Methods: The Stroke Thrombectomy and Aneurysm Registry (STAR), a multi-center international dataset, was retrospectively analyzed for anterior circulation LVO-AIS treated by MT who achieved excellent reperfusion (TICI 2c/3). The primary outcome was good functional outcome as defined by a 90-day modified Rankin Scale (mRS) 0-2. The primary study exposure was first pass success (FPS, 1 pass vs ≥2 passes) and the secondary exposure was PT. Logistic regression models were fit-adjusted and marginal effects used to assess the interaction of PT (≤30 vs >30 minutes) and FPS, adjusting for potential confounders including time from last known well to start of MT. Results: A total of 1,310 patients had excellent reperfusion. These patients were divided into two cohorts based on PT: ≤30 minutes (777 patients, 59.3%) and > 30 minutes (533 patients, 40.7%). Good functional outcome was observed in 658 patients (50.2%). The interaction term between FPS and PT was significant (p=0.018). Individuals with FPS in ≤30 minutes had 11.5% higher adjusted predicted probability of good outcome compared with those who required ≥2 passes (58.2% vs. 46.7%, p=0.001). However, there was no significant difference in the adjusted predicted probability of good outcome based on FPS in individuals with PT >30 minutes (p=0.763). This relationship appeared identical in models with PT treated as a continuous variable. Conclusion: In a large, real-world, multi-national dataset, we find that FPE is importantly modified by PT. The added clinical benefit of FPE is lost in longer procedures (>30 minutes). These data argue for a new metric for MT procedures, namely, FPE 30 , that better represents the ideal of fast, complete reperfusion with a single pass of a thrombectomy device

Ciencias sociales : desafíos y perspectivas

Es evidente que el modelo actual de difusión de la información científica, que nació en el siglo XVII, debe ser repensado como modelo de gestión o, si el lector lo desea, “como modelo de negocio” si aceptamos el lucro en el “mercado del conocimiento”. A estas alturas del desarrollo de las sociedades en que ya la revolución industrial es cosa del pasado y la sociedad ha avanzado hacia la sociedad de la información, no es posible que información científica que la ciencia genera como sistema sea rehén de pagos y que la información emergida de procesos de investigación, largos y laboriosos, quede prisionera de “proveedores” que fijan elevadas tasas para acceder a sus bases de datos y consecuentemente sólo las instituciones poderosas tienen la posibilidad de pagar esos elevados costos
