Abstract: Este artículo presenta el resultado del proyecto de investigación "Eficacia del incidente de desacato. Estudio de caso, Bogotá (2007)", cuyo propósito era identificar y analizar las variables que inciden en la eficacia de los incidentes de desacato que se interponen en búsqueda del cumplimiento de las sentencias de tutela. Se trata de una investigación cuantitativa de alcance exploratorio, en la que se examinaron 431 expedientes de desacato de juzgados penales, civiles, administrativos, laborales y de familia en la ciudad de Bogotá del a o 2007. El estudio muestra un panorama de ineficacia del incidente de desacato y la necesidad no solo de repensar el incidente de desacato, sino de desarrollar otras herramientas para promover el cumplimiento desde otras perspectivas teóricas. This paper presents the results of the research project "The Effectiveness of Judicial Contempt Power in Writ of Protection Cases. A Case Study, Bogotá (2007)".

Iatreia , 1996,
Abstract: Con el objeto de evaluar la respuesta a dos esquemas de Inmunoterapia alergénica para el tratamiento de la conjuntivitis alérgica crónica (CAC) en Individuos sensibles a Dermatophagoides farinae (ácaro del polvo) y refractarios a los tratamientos convencionales, se realizó un ensayo clínico controlado y ciego en el Hospital Universitario San Vicente de Paúl de Medellín, Colombia, entre agosto de 1990 y junio de 1993. Se estudiaron 18 hombres (82%) y 4 (18%) mujeres con edades entre los 5 y 25 a os pero en su mayoría menores de 11 a os (63.6%); la evolución de su enfermedad era mayor de 5 meses. Se excluyeron los pacientes que habían recibido previamente algún esquema de Inmunoterapia o que eran sensibles a otros aeroalergenos. En 14 pacientes (63.6%) se administró el esquema agrupado (tipo cluster) y en ocho (36.4%) el convencional. No se encontraron diferencias estadísticamente significativas entre las dos modalidades; en 16 pacientes (72.7%) hubo mejoría subjetiva parcial, demostrada por el interrogatorio, y en 15 (68.2%) mejoría objetiva parcial evidenciada por el examen oftalmológico. En tres pacientes de tratamiento agrupado no se obtuvo mejoría. Los síntomas que más disminuyeron al finalizar el seguimiento fueron el prurito en 16 casos (72.7%) y ellagrimeo (15 casos; 68.2%); sólo en 4 de los 11 pacientes (36.4%) que al Inicio del estudio tenían papllas se observó la desaparición de éstas, a pesar de una buena respuesta clínica. Se concluyó que la inmunoterapla es útil en el manejo de la CAC refractaria a tratamientos convencionales y no se encontraron diferencias significativas entre los dos esquemas utilizados. Between August 1990 and June 1993, a blind clinic assay was carried out at Hospital Universitario San Vicente de Paúl, in Mede1lín, Colombia, with the purpose of evaluating the response to two Immunotherapy schemes (cluster and conventional), for treatment of Chronic Allergic Conjunctivitis (CAC) refractory to conventional pharmacological treatments. In patients sensitized to Dermatophagoides farinae. The study was performed on 22 patients aged 5-25 years. The evolution of the disease had been 6 months or longer. Patients who had previously received an Im. munotherapy scheme or showed sensitivity to other aeroallergens were excluded. Fourteen patients (63.6%) received the cluster scheme and eight (36.4%) the conventional one. No statistically significant differences were found between the two groups. In 16 patientes (72.7%) partial subjective Improvement and in 15 (68.2%) partial objective improvement were observed. Most notoriously Improv

Abstract: the column generation algorithm (cga) is commonly cited in the bibliography as alternative to solve large scale optimization problems. this article deals with the description of the gc algorithm in the context of the student assignation to the public schools. ksome of the weaknesses and shortcomings encountered in the implementation and application to a real problem are discussed and some strategies to sort it out are presented. this workpointed out how the cga could be used within a general branch and price procedure to solve problems with additional constrains.
Aspectos controvertidos en el trastorno de déficit de atención
Etchepareborda,Máximo C.; Díaz Lucero,Andrés;
Medicina (Buenos Aires) , 2009,
Abstract: in the last decades there have been those in favor of recognizing the attention deficit disorder (add) as a neurodevelopment entity with a strong neurobiological basis responding to a specific interdisciplinary treatment versus those who think, sustain and defend that the accumulated scientific evidence is not sufficient to justify the disorder as a development anomaly in need of a specific therapeutic outline. the attention model versus the autoregulation model are described. the neurological basis of the disorder is discussed analyzing the use of functional neuroimages such as pet (positron emission tomography), spect (single photon emission tomography) and fmr (functional magnetic resonance) neuroanatomy, neurophysiology, neurochemistry of neurotransmitters up to genetics. the importance of an adequate diagnosis is emphasized, analyzing the cognitive areas involved and trying to differentiate the add types, and to determine in some cases the phenotype or phenocopy of the disorder. the different treatments advocated are discussed taking into account the interdisciplinary approaches. finally, a complete analysis of the information available is presented and conclusions are drawn to facilitate the understanding of this disorder.
Aspectos controvertidos en el trastorno de déficit de atención Controversial aspects of the attention deficit disorder

Medicina (Buenos Aires) , 2009,
Abstract: En las últimas décadas hemos visto como se han ido distanciando quienes están a favor de reconocer al TDAH como un trastorno del neurodesarrollo con fuerte base neurobiológica, que responde a un tratamiento específico de modalidad interdisciplinar y por otro lado, quienes piensan, sostienen y defienden que la evidencia científica acumulada no es suficiente para justificar la presencia de este cuadro como una anormalidad del desarrollo que merecería un abordaje terapéutico propio. Se describen las hipótesis del modelo atencional versus modelo de autorregulación, Se exponen las bases neurobiológicas del trastorno, haciendo un análisis desde las neuroimágenes funcionales, como por ejemplo el PET (tomografía por emisión de positrones), SPECT (tomografía de emisión de fotón único) y la RMF (resonancia magnética funcional), neuroanatomía, neurofisiología, neuroquímica de neurotransmisores hasta la genética. Luego se hace hincapié en las características del abordaje diagnóstico adecuado, analizando las áreas cognitivas involucradas en el trastorno, que nos posibilitará diferenciar los tipos de TDAH y en algunos casos el origen del trastorno, ya sea fenotipo o fenocopia. También se enumera una recopilación sobre la evidencia preexistente con respecto al tratamiento del TDAH y cuales tienen que ser las características de un abordaje completo e interdisciplinar. Por ultimo se hace un análisis de toda la información y se dan conclusiones útiles para la comprensión del trastorno.

Abstract: This study investigated the effects of replacing casein with soy flour on the fatty acids profile and triglycerides metabolism in the liver of rats that were previously fed with normocaloric and hypercaloric diets based on casein. Wistar male rats were used; one group was fed with control diet (AIN-93) and another with hypercaloric diet (AIN-93 with 34.15% sucrose, 42% fat calories) for 9 weeks. Each group was then divided into two subgroups and casein was replaced with soybean in one of them, obtaining CC (control casein), CS (control soy), HC (hypercaloric casein) and HS (hypercaloric soy), which were fed for 6 weeks. We measured triglycerides in serum, and triglycerides, total lipids, fatty acids profile, the expression of apolipoprotein B (Apo B), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), sterol-regulatory element-binding protein 1c (SREBP-1c), mitochondrial glycerol-3-phosphate acyltransferase (mGPAT), diacylglycerol acyltransferase 2 (DGAT-2), carnitine palmitoyltransferase 1 (CPT-1) and peroxisome proliferator-activated receptors alpha (PPARα) in liver. Histological studies were also performed. When comparing HS vs. HC, a positive effect of soybean flour on hepatic triglycerides deposits was found, possibly through the reduction in DGAT-2 expression (P < 0.01) and the increase in Apo B (P < 0.001) expression. Soybean flour also decreased fat deposits in control diets when compared with casein, decreasing the DGAT-2 (P < 0.001) expression and increasing Apo B (P < 0.001), CPT-1 (P < 0.05) and PPARα (P < 0.01) expressions. Both soy diet subgroups increased unsaturated fatty acids respect to casein diets (P < 0.01). Hepatocytes showed few lipid droplets in HS, whereas a fat deposit in HC was observed. These results suggest that replacing casein with soybean flour in normocaloric and hypercaloric diets reduces triglycerides and improves fatty acids profile in rat liver.

Abstract: PURPOSE: To describe the tendency of reference tariffs in recent years in three colombian institutions (Sociedad Colombiana de Patología Clínica —SCPC—, Instituto de Seguros Sociales —ISS— and Ministry of Health), for the three laboratory tests with greater demand, namely: glucose test, urine analysis and blood count. Methodology: The tariffs for these tests in the aforementioned institutions were analyzed since first available until 2003. Tariffs of the SCPC are adjusted according to official price indexes and the minimum salary. A comparison year after year was carried out. Results: The proposed tariffs of the SCPC were very closely similar to the adjustments by economic indicators. Prices of the glucose test were on the average 61,3% lower in the ISS and 45,2% lower in the Ministry of Health as compared with the SCPC. Prices of the urine analysis were on the average 58,9% lower in the ISS and 49,4% lower in the Ministry of Health than in the SCPC. Prices for the blood count were on the average 36,5% lower in the ISS and 31,8% lower in the Ministry of Health than in the SCPC. Conclusion: Tariffs for the three evaluated tests are lower in the ISS and the Ministry of Health and the gap with those of the SCPC becomes wider every year. Objetivo: Describir el comportamiento en los últimos a os de las tarifas de referencia de la Sociedad Colombiana de Patología Clínica (SCPC), el Instituto de Seguros Sociales (ISS) y el Ministerio de Salud (MS), de los tres exámenes de mayor demanda en el laboratorio clínico: la glicemia, el citoquímico de orina y el hemograma. Metodología: Se tomó la tarifa propuesta para las tres pruebas por las tres instituciones desde su inicio hasta el 2003. Las de la SCPC fueron ajustadas también por el índice de precios al consumidor y el salario mínimo. Se realizó una comparación a o a a o. Resultados: Las tarifas propuestas por la SCPC fueron muy similares a los ajustes por indicadores económicos. Las tarifas de la glicemia fueron en promedio un 61,3% más bajas en el ISS y un 45,2% más bajas en el MS comparadas con las de la SCPC. Las tarifas del citoquímico de orina fueron en promedio un 58,9% más bajas en el ISS y un 49,4% más bajas en el MS comparadas con las de la SCPC. Las tarifas de los hemogramas fueron en promedio un 36,5% más bajas en el ISS y un 31,8% más bajas en el MS comparadas con las de la SCPC Conclusión: en las tres pruebas evaluadas la diferencia entre las tarifas del ISS y el MS se va haciendo mayor a o a a o comparadas con las de la Sociedad Colombiana de Patología Clínica.
