OBJECTIVE: To evaluate the risk of IgE sensitization and symptoms to shrimp in a population that has received AIT with polymerized mite extract. METHODS: Patients with allergic rhinitis sensitized to dust mites (Dermatophogides spp) with an indication for mite AIT were included. Those patients who had not yet received AIT or had received less than 6 doses were included as controls and those who had received more than 24 doses of AIT were included as cases. Sensitization to shrimp was assessed by skin prick test with complete shrimp extract and/or shrimp-specific IgE. RESULTS: A total of 68 patients were included; 47 cases and 21 controls. When calculating the odds ratio of sensitization according to time with immunotherapy we observed that there were no differences between the group of cases and controls (OR 0.76 95% CI 0.26 to 2.22 p 0.7 by MacNemar technique). Factors such as consumption or not of shrimp and frequency of consumption do not seem to be related to the outcome. CONCLUSION: In contrast to what was reported with aqueous extracts, we observed that AIT with polymerized extracts is not a risk factor for shrimp sensitization. It is necessary to reproduce these results with a larger sample size to explore other factors.


OBJETIVO: Evaluar el riesgo de sensibilización IgE y síntomas a camarón en una población que ha recibido AIT con extracto polimerizado para ácaros. MÉTODOS: Se incluyeron pacientes con rinitis alérgica sensibilizados a ácaros del polvo (Dermatophogides spp) con indicación de AIT para ácaros. Aquellos pacientes que no habían aún recibido AIT o llevaban menos de seis dosis, fueron incluidos como controles, y aquellos que llevaban más de 24 dosis de AIT, fueron incluidos como casos. Se evaluó la sensibilización a camarón mediante prueba cutánea con extracto completo de camarón y/o IgE específica a camarón. RESULTADOS: En total, 68 pacientes fueron incluidos; 47 casos y 21 controles. Al calcular el odds ratio de la sensibilización de acuerdo al tiempo con la inmunoterapia, observamos que no había diferencias entre el grupo de casos y controles (OR 0,76 95% IC 0,26 a 2,22 p 0,7 por técnica de MacNemar). Factores como el consumo o no de camarón y la frecuencia de consumo, no parecen estar relacionados con el desenlace. CONCLUSIÓN: A diferencia de lo reportado con extractos acuosos, observamos de AIT con extractos polimerizados para no es un factor de riesgo para la sensibilización a camarón. Es necesario reproducir estos resultados con un mayor tamaño de muestra que permita explorar otros factores.

According to the World Health Organization, dengue is a neglected tropical disease. Latin America, specifically Colombia is in alert regarding this arbovirosis as there was a spike in the number of reported dengue cases at the beginning of 2019. Although there has been a worldwide decrease in the number of reported dengue cases, Colombia has shown a growing trend over the past few years. This study performed a Poisson multilevel analysis with mixed effects on STATA® version 16 and R to assess sociodemographic, climatic, and entomological factors that may influence the occurrence of dengue in three municipalities for the period 2010-2015. Information on dengue cases and their sociodemographic variables was collected from the National Public Health Surveillance System (SIVIGILA) records. For climatic variables (temperature, relative humidity, and precipitation), we used the information registered by the weather stations located in the study area, which are managed by the Instituto de Hidrologia, Meteorologia y Estudios Ambientales (IDEAM) or the Corporación Autónoma Regional (CAR). The entomological variables (house index, container index, and Breteau index) were provided by the Health office of the Cundinamarca department. SIVIGILA reported 1921 dengue cases and 56 severe dengue cases in the three municipalities; of them, three died. One out of four cases occurred in rural areas. The age category most affected was adulthood, and there were no statistical differences in the number of cases between sexes. The Poisson multilevel analysis with the best fit model explained the presentation of cases were temperature, relative humidity, precipitation, childhood, live in urban area and the contributory healthcare system. The temperature had the biggest influence on the presentation of dengue cases in this region between 2010 and 2015.

This study evaluated the sustainability of a set of interventions to prevent dengue and diarrhea in 33 rural schools in the municipalities (counties) of Anapoima and La Mesa, Colombia, two years post-project. The study measured sustainability in two categories: maintenance of the benefits and the interventions, and institutionalization and community capacity-building. The sustainability of the interventions was compared across four arms: interventions to prevent diarrhea, to prevent dengue, combined interventions to prevent diarrhea and dengue, and control. The final score for each arm was classified in five levels of sustainability: regressive, not sustainable, moderately sustainable, sustainable, and highly sustainable. The arms were compared with ANOVA and Kruskal-Wallis test, with significance set at 0.05. At two years post-project, the overall sustainability for the prevention of diarrhea was moderate in the four arms, while dengue prevention was not sustainable in three of the four arms, without statistically significant differences. Sustainability levels also varied in terms of benefits, interventions, capacity-building, and institutionalization. Maintenance of benefits and interventions in both diseases was more sustainable than institutionalization and capacity-building. The analysis of these variables is important for identifying the different factors that influence projects' sustainability, related to their design and execution, organizational framework, and social context.


Este estudio evaluó la sostenibilidad de un conjunto de intervenciones para la prevención del dengue y la diarrea, en 33 escuelas rurales en los municipios de Anapoima y La Mesa, Colombia, dos años post-proyecto. Se midió la sostenibilidad en dos categorías: mantenimiento de los beneficios e intervenciones, e institucionalización y desarrollo de capacidades de la comunidad. Se comparó la sostenibilidad de las intervenciones que fueron distribuidas en cuatro brazos: intervenciones para prevenir la diarrea, para prevenir el dengue, combinadas para prevenir la diarrea y el dengue, y control. El puntaje final de cada brazo se clasificó en uno de cinco niveles de sostenibilidad: regresivo, no sostenible, moderadamente sostenible, sostenible y altamente sostenible. Se compararon los brazos mediante las pruebas ANOVA y Kruskal-Wallis, con un nivel de significancia de 0,05. A los dos años post-proyecto, se observa que el nivel total de sostenibilidad para la prevención de diarrea fue moderadamente sostenible en los cuatro brazos y para dengue no sostenible en tres de los cuatro brazos, sin encontrar diferencias estadísticamente significativas entre estos. También se observa que los niveles de sostenibilidad varían, en cuanto a los beneficios, intervenciones, desarrollo de capacidades e institucionalización. El mantenimiento de los beneficios y de las intervenciones en ambas enfermedades fue más sostenible que la institucionalización y desarrollo de capacidades. Es importante el análisis de estas variables para identificar los diferentes factores que influyen en la sostenibilidad de los proyectos, relacionados con el diseño y ejecución de estos, con el marco organizacional, y con el contexto social.

A sustentabilidade foi medida em duas categorias: manutenção dos benefícios e intervenções, e institucionalização e desenvolvimento de capacidades da comunidade. Foi comparada a sustentabilidade das intervenções que foram distribuídas em quatro áreas: intervenções para prevenir a diarreia, e também o dengue, combinadas para prevenir a diarreia e o dengue, e o controle. A pontuação final de cada área foi classificada em um entre cinco níveis de sustentabilidade: regressivo, não sustentável, moderadamente sustentável, sustentável e altamente sustentável. As diferentes áreas foram comparadas através das provas ANOVA e Kruskal-Wallis, com um nível de significância de 0,05. Em dois anos pós-projeto, foi observado que o nível total de sustentabilidade para a prevenção de diarreia foi moderadamente sustentável nas quatro áreas e para dengue não sustentável em três das quatro áreas, sem encontrar diferenças estatisticamente significativas entre elas. Também foi observado que os níveis de sustentabilidade variam, em quanto aos benefícios, intervenções, desenvolvimento de capacidades e institucionalização. A manutenção dos benefícios e das intervenções em ambas as doenças foi mais sustentável do que a institucionalização e desenvolvimento de capacidades. É importante o análise destas variáveis para identificar os diferentes fatores que influem na sustentabilidade dos projetos, em relação com o desenho e execução destes, com o marco organizativo, e com o contexto social.

Previous studies show that stress cross-sensitizes with or alters amphetamine (AMPH) effects in male rats; however, few studies include females. We investigated combining daily restraint stress (21 days for 6 h/day) with chronic AMPH (10 injections every other day) on locomotor activity, exploratory activity in an open field and object recognition, a memory task, in female rats. A synaptic protein, synaptophysin, was also quantified by radioimmunocytochemistry (RICC) in brain to determine possible mechanisms for behavioral changes. Beginning at 5 days after cessation of treatments, AMPH increased locomotion, modified exploration, impaired object recognition, and increased serum corticosterone (CORT) levels. Stress did not alter these parameters but blocked AMPH effects on exploration and object recognition, potentiated AMPH-dependent locomotor effects, and did not alter increased CORT levels. AMPH treatment decreased synatophysin expression in the hippocampus. In the caudate nucleus, the AMPH group showed increased synaptophysin expression which was reversed by stress. These results in females corroborate previously shown cross-sensitizations between stress and AMPH for locomotion in males and demonstrate that chronic stress counteracts AMPH-dependent impairments in recognition memory. Stress may counteract AMPH effects on the memory task by blocking both the induction of AMPH anxiety-like effects and neuroplastic changes in the caudate nucleus of female rats.
