López-Castillo,Christian A.; Díaz-Ramírez,Julieth; Gómez-Marín,Jorge E.;
Revista de Salud Pública , 2005, DOI: 10.1590/S0124-00642005000200006
Abstract: objectives: to determine the risk factors associated with acute toxoplasmosis during pregnancy in armenia. methods: case-control study; 14 cases and 34 controls (mean ages 23±5.5 and 23±5.1 respectively; p = 0.93). cases were pregnant women with serological criteria for acute toxoplasmosis and controls were seronegative pregnant women for toxoplasma igg. results: the risk factors more strongly predictive of acute toxoplasmosis in pregnant women were: eating undercooked meat (or: 13.2; 95% ci: 1.3-132; p = 0.01), drinking beverages prepared with un-boiled water (or: 4.5; 95% ci: 1.1-17; p = 0.01), and contact with cats aged less than 6 months (or: undefined, p = 0.01). drinking of bottled water was a protective factor (or: 0.24; 95% ci: 0.06-0.95; p = 0.02). conclusions: 42% of toxoplasma gondii infections in pregnant women armenia were associated to contact with young cats and to consumption of undercooked meat. drinking of bottled water to prevent toxoplasma infection during pregnancy is also recommended.
Cuestiones sobre la lógica de la argumentación Questions on the logic of the argumentation
Raúl Gómez-Marín
Ingeniería y Ciencia , 2009,
Abstract: En el ámbito de las teorías de la argumentación se suele decir que la lógica no cuenta con los elementos necesarios para fundamentar lógicamente los argumentos más relevantes que se realizan en el marco de las teorías jurídicas, políticas, psicológicas, humanísticas e incluso de las teorías científicas. Si con el término lógica se hace referencia a la lógica clásica, el autor está de acuerdo. Empero, si se tienen en cuenta los aportes de las familias de lógicas no–clásicas, el autor no cree que sea pertinente afirmar categóricamente tal asunto. Se puede comprender por qué la pregunta que orienta esta investigación es: para una determinada teoría que tenga alguna pretensión de objetividad, es posible hallar o construir un sistema de lógica que cuente con los elementos y la estructura necesaria para modelar la estructura de su lógica subyacente? Este trabajo busca ubicarse en un justo medio: se afirma que sí es posible, y se intentará mostrar que las lógicas no–clásicas abren vías, hasta ahora desconocidas, para repensar los fundamentos lógicos de la razón pragmática. Y no es posible, porque se reconoce que en una argumentación racional se usan reglas que no son puramente lógicas. In the argumentative theory eld is usually said that the logic has not the necessary elements to found the logical bases for the most relevant arguments in use in the juridical, political, and human theories, even the scienti c ones. If the term “logic” refers only to the classical logic, of course, the author agrees. But if one takes into account the contributions of the families of non–classical logics, the author does not believe relevant to state categorically that.One can understand why the question that guides this research is the following:Given a theory which has some pretension of objectivity, is it possible to nd a“non–classical logical system” having the elements and the structure necessary to model its underlying logic? In this research, it is o ered a intermediate answer: yes, it is possible, because the “non–classical logical system” open a way to research the foundation of pragmatic reason. And, no, it is not possible, because it is recognized that in a rational argument are used rules that are not purely logical.

Abstract: Objetivos: establecer el punto de corte de una prueba ELISA IgG de avidez casera en el Centro de Investigaciones Biomédicas de la Universidad del Quindío y correlacionar sus resultados con la fecha de gestación y resultados de IgM e IgA en sueros de pacientes gestantes, analizadas en el laboratorio para establecer el perfil de uso de la prueba. Materiales y métodos: se estudiaron sueros de 17 pacientes con fechas de infección conocidas, para definir la curva receptor operador (ROC) por la prueba ELISA IgG de avidez anti Toxoplasma y 91 sueros de pacientes embarazadas con resultados de pruebas IgM e IgA anti Toxoplasma analizadas en el mismo laboratorio. Resultados: obtuvimos un punto de corte de avidez menor a 30%, lo que permite una sensibilidad del 100% y una especificidad del 88% para definir si la infección tenía menos de 4 meses de adquirida. En el segundo grupo, de 91 pacientes, encontramos que el 63% tenía menos de 16 semanas de gestación al momento de la prueba y 3 pacientes tuvieron índices de avidez bajo (<30%). Se observa que a la mayoría de pacientes se les solicitó la prueba antes de la semana 16 de gestación, lo cual es un indicador de buen uso de la prueba. Conclusiones: un punto de corte de 30% para la prueba ELISA de avidez anti Toxoplasma casera en el Centro de Investigaciones Biomédicas de la Universidad del Quindío, identifica infecciones de menos de 4 meses de adquirida.

Abstract: Introducción: el diagnóstico de catarata por ecografía prenatal es un hallazgo poco frecuente y se ha reportado aún con menor frecuencia en casos de infecciones congénitas. El presente reporte describe un caso de catarata congénita durante una infección por Toxoplasma en el embarazo. Los estudios prenatales y posnatales confirmaron la etiología. Metodología: estudio de caso y revisión de literatura. Se hizo búsqueda en PubMed de MEDLInE con los términos sin restricción: "ultrasonido", "ultrasonografía", "cataratas" y "prenatal". Resultados: se hallaron 43 referencias. Sólo uno de los documentos reportaba hallazgo de catarata por ecografía prenatal en toxoplasmosis congénita. Conclusión: la búsqueda cuidadosa de compromiso ocular durante el estudio ecográfico en la toxoplasmosis adquirida durante el embarazo debería ser un componente clave del estudio ecográfico durante esta infección.

Cadernos de Saúde Pública , 1997,
Abstract: Las tasas de mortalidad por cardiopatía isquémica (CI) han sido utilizadas ampliamente en el diagnóstico de la salud cardiovascular de regiones y países. Sin embargo, su validez ha sido cuestionada fundamentalmente por lo que le da origen: el certificado de defunción (CDD). El presente estudio tiene el objetivo de establecer la validez del diagnóstico "infarto de miocardio (IM)" como causa de muerte en los CDD de muertes intra-hospitalarias en la ciudad de Barquisimeto, Estado Lara, Venezuela. Entre julio de 1991 y junio de 1992, se identificaron todos los CDD con las características mencionadas, se trató de ubicar la historia clínica correspondiente a cada caso y cualquier otra información clínica pertinente. Se registraron 247 CDD elegibles y se ubicó información clínica adecuada en 136 casos (55%). Aplicando los criterios del Proyecto MONICA, se encontraron M-definitivo en 62 casos (45,6%), IM-probable en 31 casos (22,8%) y No-IM en 43 casos (31,6%). Los resultados indican que existe un sobre registro de casos de muerte por IM del 32% (intervalo de confianza del 95% = 23,8-39,4). A la luz de estos resultados es necesario estudiar los factores que inciden en la exactitud de los diagnósticos IM en los CDD. Con esto tendríamos elementos para revisar las normas y los procedimientos empleados en la producción y manejo de los CDD, así como preparar un programa de educación para mejorar la precisión de los mismos.

Abstract: La tuberculosis es uno de los problemas que demanda atención prioritaria en el municipio de Armenia, capital del departamento del Quindío (Colombia). En este estudio, se encontró que la población afectada, generalmente pertenece al género masculino (razón hombre: mujer 2:1) y en edad económicamente productiva (25-54 a os). La mayoría de enfermos son del régimen subsidiado (40%) o no asegurados (26%) y viven en condiciones socioeconómicas críticas. Se encontraron diferencias significativas de carga de enfermedad en las tasas entre comunas: en unas localidades fueron de 10 y en otras de 30 casos por 100.000 habitantes, indicando heterogeneidad de la situación en la ciudad. El análisis geoespacial permite caracterizar y precisar los escenarios donde se deben concentrar las acciones prioritarias del programa de control de la tuberculosis. Tuberculosis is an important public health problem that demands priority action in the city of Armenia (Colombia). In this study, we found that most cases of TB were males (ratio 2:1) and economically active population (25-54 years). TB patients had subvention health care (40%) or were uncovered by the national health insurance (26%), living in critical socioeconomic condi tions. Significant differences in the TB prevalence rate between town localities were found; in some zones were 10 and 30 cases per 100.000 inhabitants, indicating a heterogeneous situation. Spatial analysis might allow the definition and concentration of early actions in a region for the tuberculosis control.

Abstract: introduction: pcr detection offers a good opportunity to obtain fast results which is a priority in tuberculosis control programs. objectives: we assayed an in-house pcr method based on the detection of mycobaterial is6110 gene in clinical samples of patients with pulmonary and extrapulmonary tuberculosis to demonstrate its usefulness and reliability in the setting of a middle-resource region with high tuberculosis prevalence. materials and methods: pulmonary (n=317) and extrapulmonary (n=41) samples were collected from 358 patients with clinical suspicion of tuberculosis. all samples were processed to detect acid-fast bacilli by microscopy, culture on solid media and pcr. to remove pcr inhibitors, three washing steps of the decontaminated pellet were included before mycobacterial cell lysis. results: the overall sensitivity was 96% in clinical samples, and specificity was 100% for our in-house method in pulmonary and extrapulmonary samples. no inhibition was found among samples that were pcr negative, but culture positive for mycobacterium tuberculosis. no false positives were found. conclusions: in-house pcr in a middle-income setting region, with simple and strictly controlled methods, could efficiently complement conventional bacteriological tools for the rapid diagnosis of tuberculosis, especially in paucibacillary and extrapulmonary samples.
