El flujómetro de Wright: Una herramienta indispensable en la práctica ambulatoria
Sepúlveda M,Ricardo;
Revista chilena de enfermedades respiratorias , 2004, DOI: 10.4067/S0717-73482004000200004
Abstract: in spite of the general agreement of proven utility of pulmonary function evaluation in helping health care professionals to make right decisions with respiratory patients in specific clinical circumstances, the daily life activity does not include these measurements. this approach differs with the regular use of ecg, glucose, cholesterol, arterial blood pressure measurement or even chest x ray. spirometer limited availability in out-patient setting was the most common argument to back this attitude. for more than 20 years a very economic, reliable and portable equipment to measure the peak expiratory flows, is available to be used in out-patient clinics. this portable flow meter, allows to evaluate the obstructive component of the respiratory diseases in patients home, work and clinics and to make evident, possible changes produced by therapeutic interventions. the big proportion of obstructive diseases in clinical practice make necessary to get such instrument on daily activities, all international guidelines to treat asthmatic patients include the regular measurement of peak expiratory flow in their exacerbations, as well as in their out-patient clinics medical control. this information is a basic requirement to get proper asthma control and to get good quality intervention in respiratory patients with a bronchial obstructive component
El flujómetro de Wright: Una herramienta indispensable en la práctica ambulatoria Wright portable Peak Flow-meter: A "must" in out-patient clinic

Abstract: La evaluación de la Función Respiratoria (FR) a pesar de su demostrada utilidad diagnóstica, pronóstica y de evaluación de la eficacia terapéutica, no ha sido incorporada en forma habitual a la práctica clínica ambulatoria, como lo ha sido el ECG, la glicemia, el esfingomanómetro e incluso la radiografía de tórax. La falta de accesibilidad al equipamiento necesario ha sido una de sus justificaciones. Hace más de 20 a os que se dispone de un sencillo equipo portátil, de bajo costo que puede medir los flujos espiratorios máximos denominado flujómetro y que en variadas versiones ha venido a colaborar en la objetivación del componente obstructivo de las enfermedades respiratorias en la consulta ambulatoria, e incluso en el domicilio o trabajo del paciente. Esta evaluación parcial de la FR, viene a cubrir al grupo mayoritario de pacientes respiratorios crónicos, y a pesar de sus limitaciones asociadas a la necesaria cooperación para su ejecución, su fácil repetición en el tiempo y en diversas condiciones, le confiere un valor inapreciable en la práctica médica diaria. Los asmáticos, tanto durante sus exacerbaciones como en los controles periódicos, son el grupo que lo requiere en forma imprescindible si se quieren cumplir los objetivos terapéuticos acordados internacionalmente como normas mínimas de calidad In spite of the general agreement of proven utility of pulmonary function evaluation in helping health care professionals to make right decisions with respiratory patients in specific clinical circumstances, the daily life activity does not include these measurements.

Abstract: Antecedentes: En embarazadas seropositivas sin profilaxis antirretroviral la transmisión vertical (TV) del VIH es de 30%, cifra que disminuye bajo al 2% con un manejo integral de prevención. Objetivo: Conocer el comportamiento epidemiológico de la TV en Chile desde la creación del programa nacional de prevención. Método: Datos aportados por el Departamento de Epidemiología del MINSAL y CONASIDA (1984-2006). Estudió de situación VIH/SIDA por a o, regiones, grupo etario y sexo, con especial énfasis en TV. Resultados: Se notificaron 9.317 casos de VIH y 7.886 casos de SIDA (1984-2006), prevalencia en aumento hasta el 2003 con tendencia descendente posteriormente. La razón actual de VIH entre hombres y mujeres es de 4:1, con clara tendencia al aumento de notificación en mujeres. La principal vía de exposición sigue siendo la vía sexual (93,4%). El grupo más afectado está entre los 20-39 a os (73,1% para VIH y 63,1% para SIDA), cabe destacar que entre 0-9 a os se encuentra el 1,1% de los afectados por VIH y el 1,4% por SIDA, todos infectados por TV. Conclusiones: La transmisión vertical de VIH en Chile es responsable de un bajo porcentaje de las personas notificadas de VIH/SIDA, pero es la causa de la totalidad de los ni os afectados por la infección en nuestro país. Se observa una importante reducción de la TV, llegando a niveles muy cercanos a los objetivos ministeriales. Background: The risk of transmitting HIV from mother to unborn child, without any antiretroviral prophylaxis, reaches 30%. It can be reduced to less than 2% by implementing integral preventive strategies. Objective: To assess the epidemiological profile of HIV vertical transmission in Chile since the implementation of the national AIDS transmission prevention program. Method: Data from the Epidemiology Department of the Health Ministry and the National Commission for AIDS grouped by year, location, ageandgender. Withspecial emphasis on vertical transmission. Results: 9317 cases of HIV infection and 7886 cases of AIDS have been reported in Chile (1984-2006), with a decreasing tendency since 2003. Sexual exposure continues to be the primary route with 93.4% of the cases. The male/female ratio for case notif cation is 4:1, with a rising tendency among women. The most affected is between 20-39 years old (73% HIV notification and 63.1% for AIDS). Among children between 0-9 years of age is 1.1% of the HIV and 1.4% of AIDS notifications, all of them for vertical transmission. Conclusions: HIV vertical transmission in Chile is responsible for a small percentage of HIV/AIDS notifications, but it a

Abstract: Introducción: Las condiciones sociales y factores biológicos representados por variables reproductivas, clínicas, de hábitos y la conducta de cuidado materno en prevención de enfermedades respiratorias, constituyen una prioridad en el contexto socioeconómico cultural de la IX Región. Objetivos: Relacionar la conducta de cuidado materno en prevención de Infecciones Respiratorias Agudas (IRA) con la presencia de SBO y NAC. Metodología: Investigación descriptiva, correlacional, en muestra probabilística, secuencial de 239 lactantes y sus madres. Los datos se recolectaron en cuestionario validado y adaptado a las necesidades de la investigación. Se realizó análisis descriptivo y analítico, con prueba de chi cuadrado, prueba exacta de Fisher. La investigación cumplió con los Requisitos éticos de Ezequiel Emmanuel. Resultados: La conducta "evita fuentes de contagio" frecuentemente 49,8%, "ventila su hogar" frecuentemente 42,4%, "se preocupa de calefaccionar su hogar" frecuentemente 43,5%, "evita exponer al lactante a cambios bruscos de temperatura" frecuentemente 39,0% y "se siente preparada para entregar cuidados básicos de salud a su hijo" frecuentemente, 42,8%. Discusión y Conclusiones: El Síndrome Bronquial Obstructivo (SBO) se asoció a la conducta de cuidado; las madres revelaron déficit en la conducta de cuidado hacia su hijo (conducta de calefaccionar, ventilar y evitar fuentes de contagio en su hogar), lo que reafirma el propósito de generar una línea educativa dirigida a madres de lactantes con factores de riesgo.

Abstract: considering the high level of concern caused by genetically modified foods (gmf) in developed countries, the relevance of this variable in decision-making about the purchase of fluid milk among consumers in temuco (la araucanía region, chile) was determined. by means of a personal survey of 400 people and using conjoint analysis, it was determined that the presence of genetic modifications in food was more important (44.7%) than brand (29.5%) and price (25.5%) in the decision-making process. by cluster analysis three segments were identified; the largest group (46.5%) gave similar relevance to food production and brand, preferring genetically modified milk. for the second group (41.5%), the presence or absence of genetic modification was the most important variable in the purchase, with a strong rejection of milk produced by genetic manipulation and preference for non-transgenic milk. the minority segment (12.0%) placed a higher value on price. these three segments prefer national brand milk, reject the product with private brands and react positively to lower prices. the most sensitive segment to genetic food manipulation had a higher proportion of people under 35 years of age and with no children. it is concluded that the absence of genetic manipulation in food is a desirable condition, mainly for young consumers of la araucanía region.

Abstract: in underground mining, daily a fleet of lhds must be allocated to a haulage network of drifts for extracting ore according to a plan-driven strategy. this plan is hierarchically decided by a higher management level and it contains the number of ore bucketfuls to be extracted from each drawpoint within a drift for each working shift. in this paper, an integer programming (ip) model for minimizing the makespan of drift workload is formulated and a polynomial time optimal algorithm for its resolution is proposed. next, a set of decision rules obtained from the algorithm above is integrated into the decision-making process (dmp). this dmp is simple to execute for lhd operators, determines the optimal makespan, and whether or not it can be carried out in the working shift. finally, a comparative analysis between the dmp proposed and the dmp used in el teniente copper underground chilean mine is studied. the results show that the cumulative operators experience has converged to solutions near to optimal makespan.
