Uveítis pediática no infecciosa, una experiencia de una cohorte colombiana

Resumen: •Antecedentes: La uveítis pediátrica no infecciosa tiene el potencial de desencadenar severas complicaciones visuales y su manejo farmacológico convencional está asociado a importantes efectos secundarios. 1 Infliximab (INF) y Adalimumab (ADA), son dos medicamentos biológicos disponibles para el manejo de la uveítis pediátrica refractaria. Se unen específicamente al TNFα y previenen la unión del mismo con los receptores celulares; interacción directamente implicada en el proceso inflamatorio y el subsecuente daño tisular. 2,3 •Métodos: Se realizó estudio de tipo cohorte retrospectiva mediante revisión de historias clínicas de 35 pacientes pediátricos diagnosticados con uveítis durante los años 2009-2015. Se comparó control de la inflamación ocular, tiempo de respuesta y eventos adversos en pacientes tratados con ADA o INF con dosis bajas de Metotrexate vs. Metotrexate (MTX) como única terapia. •Resultados: El 45.7% de la población estudiada correspondía al sexo femenino, cuya edad promedio de inicio de síntomas y de diagnósticos fue de 9 años. El 80% de los casos fueron uveítis idiopáticas, seguido por Vogt-Koyanagi-Harada (8,5%) y AIJ (5,7%). El 91,4% presentó compromiso ocular bilateral y se documentaron 2 casos de ambliopía. El 12,9% de los pacientes que recibieron MTX como tratamiento de primera línea requirieron escalonamiento terapéutico por presentar eventos adversos (Elevación de enzimas hepáticas e intolerancia gastrointestinal (GI)). El tiempo promedio para alcanzar control de la inflamación con MTX fue 9 semanas, y para Adalimumab fue de 8,75 semanas (P: 0,90). Se comparó la capacidad de controlar la inflamación del MTX vs Anti-TNF, y no se observaron diferencias significativas (P: 0.88).

Innovación social: una reflexión sobre los beneficios en su implementación en el Estado colombiano.

La innovación social es un tipo de innovación que promueve la búsqueda de soluciones enfocadas a los problemas que se presentan en la sociedad. Estas soluciones generan además un valor agregado que ayudan al crecimiento del país. En Colombia este tipo de iniciativas han empezado a tener una gran importancia y han empezado a promover condiciones de vida más favorables y justas que buscan generar un beneficio a la sociedad y contribuir al desarrollo del país. A partir de la historia de la innovación social, ejemplos y grandes literatos en la administración y la sociología, comprenderemos la importancia de la innovación en nuestro país.

Natural disasters and clientelism: the case of floods and landslides in Colombia

What are the effects of natural disasters on electoral results? Some authors claim that catastrophes have a negative effect on the survival of leaders in a democracy because voters have a propensity to punish politicians for not preventing or poorly handling a crisis. In contrast, this paper finds that these events might be beneficial for leaders. Disasters are linked to leader survival through clientelism: they generate an in-flow of resources in the form of aid, which increase money for buying votes. Analyzing the rainy season of 2010-2011 in Colombia, considered its worst disaster in history, I use a difference-in-differences strategy to show that in the local election incumbent parties benefited from the disaster. The result is robust to different specifications and alternative explanations. Moreover, places receiving more aid and those with judicial evidence of vote-buying irregularities, are more likely to reelect the incumbent, supporting the mechanism proposed by this paper.

On the design of education conditional cash transfer programs and non education outcomes: the case of teenage pregnancy

We investigate the effect of education Conditional Cash Transfer programs (CCTs) on teenage pregnancy. Our main concern is with how the size and sign of the effect may depend on the design of the program. Using a simple model we show that an education CCT that conditions renewal on school performance reduces teenage pregnancy; the program can increase teenage pregnancy if it does not condition on school performance. Then, using an original data base, we estimate the causal impact on teenage pregnancy of two education CCTs implemented in Bogot´a (Subsidio Educativo, SE, and Familias en Acci´on, FA); both programs differ particularly on whether school success is a condition for renewal or not. We show that SE has negative average effect on teenage pregnancy while FA has a null average effect. We also find that SE has either null or no effect for adolescents in all age and grade groups while FA has positive, null or negative effects for adolescents in different age and grade groups. Since SE conditions renewal on school success and FA does not, we can argue that the empirical results are consistent with the predictions of our model and that conditioning renewal of the subsidy on school success crucially determines the effect of the subsidy on teenage pregnancy

Short Term Health Shocks and School Attendance: The Case of a Dengue Fever Outbreak in Colombia.

This paper makes use of a short, sharp, unexpected health shock in the form of the 2010 Colombian Dengue outbreak to examine the direct and indirect impact of negative health shocks on behaviour of households in affected areas. Our analysis combines data from several sources in order to obtain a comprehensive picture of the influence of the outbreak, and furthermore to understand the underlying mechanisms driving the effects. Our initial analysis indicates that the outbreak had a substantial negative effect on the health status of adults and adversely affected their ability to function as usual in their daily lives. In our aggregated school data, in areas with high levels of haemorrhagic Dengue we observe a reduction innational exam attendance (last year of secondary school) and on enrolment rates in primary education. Further analysis aims to exploit detailed individual level data to gain a more in depth understanding of the precise channels through which this disease influenced the behaviour and outcomes of the poor in Colombia.

Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

Violence and growth in colombia : a review of the quantitative literature

This is a critical review of the empirical literature on the relationship between violence and economic growth in Colombia: an interesting case study for social scientists studying violence, conflict, crime and development. We argue that, despite the rapid development of this literature and the increasing use of new techniques, there is still much room for research. After assessing the contribution of the most influential papers on the subject, we suggest directions for future research.
