Análisis de interacciones de los actores de la red de conocimiento en salud ambiental del Observatorio Nacional de Salud de Colombia

Introducción: Las interrelaciones positivas y negativas entre el hombre y el medioambiente impactan en la salud general de la población, por esto, la gestión del conocimiento y la transformación social, orientadas a la prevención de la exposición a factores de riesgo ambiental y a la creación de ambientes propicios, deben realizarse a través de acciones multidisciplinares intersectoriales, como el trabajo colaborativo de redes del conocimiento. Objetivo: Describir las interacciones entre los actores de la Red de Conocimiento de Salud Ambiental del Observatorio Nacional de Salud de Colombia (ONS), con el fin de promover, mejorar y fortalecer la colaboración, intercambio de información y planificación conjunta de acciones. Metodología: Estudio descriptivo transversal de análisis de redes sociales mediante herramientas de minería de texto del lenguaje de programación R. Se analizaron las categorías de agua y saneamiento, clima, calidad del aire, radiaciones electromagnéticas e intoxicaciones químicas de un corpus documental de 99 textos de los actores de la red general de conocimiento en salud pública del ONS. Se calcularon medidas de centralidad y prestigio y se graficaron redes dirigidas multicapa con Power BI. Resultados: Los actores con mayor centralidad en la red fueron: Ministerio de Salud y Protección Social, Superintendencia de Salud, Profamilia, universidades de Antioquia y La Salle, ONS, Observatorio de Salud Ambiental de Bogotá, Organización Panamericana de la Salud y Organización Mundial de la Salud. Las cinco categorías analizadas presentaron bajas centralidades de grado, y las categorías de agua y clima mostraron mayor participación de los actores (más nodos e interacciones). Conclusiones: El análisis de redes sociales permitió identificar temas relevantes de salud ambiental entre los actores de la red del ONS, además de actores clave para desarrollar espacios de interacción y gestión del conocimiento. Acorde con las limitaciones del análisis, se sugiere la inclusión de aproximaciones bibliométricas para la actualización de las interacciones de la red.

Introduction: Positive and negative interactions between the human beings and the environment have an impact on the general health of the population. Therefore, it is necessary to use knowledge management and social transformation, in order to limit exposure to environmental risk factors by creating a favorable environment for healthcare. This should be carried out through multidisciplinary and intersectorial actions, such as the collaborative work of knowledge networks. Objective: To describe the interactions between the actors within the Environmental Health Knowledge Network Colombia's National Observatory of Health (ONS acronym in Spanish), in order to promote, improve and strengthen collaboration, information exchange and planning of collaborative actions. Methodology: Cross-sectional descriptive study to analyze social interactions through text mining tools by R, programmer language. Categories analyzed: Water and sanitation, climate, air quality, electromagnetic radiation and chemical poisoning. Data source: a documentary corpus of 99 texts done by actors of Environmental Health Knowledge Network of Colombia's ONS. We calculated centrality and prestige measures. We used Power BI in order to plot multi-layered directed networks. Results: Actors with greatest centrality in the network: Ministry of Health and Social Protection, Health Superintendency, Profamilia, Antioquia and La Salle universities, National Health Observatory, Bogota's Observatory of Environmental Health, the Pan American Health Organization and the World Health Organization. The five categories analyzed provides a low centrality degree, and water and climate categories presented greater participation by actors (more nodes and links). Conclusions: Social interactions analysis provides the identification of relevant environmental health issues in Colombia and key actors in order to develop interaction spaces for knowledge management. The analysis had limitations that suggest the inclusion of bibliometric approaches for updating the interactions within the network.

Educational inequalities in heart failure mortality and the cycles of the internal armed conflict in Colombia: An observational panel study of ecological data, 1999-2017.

Heart failure (HF) is a significant clinical problem and an important public health issue due to the morbidity and mortality that it causes, especially in a population that is aging and affected by social stressors such as armed conflict. We aim to describe the inequalities and trends of HF mortality by educational level in Colombia between 1999 and 2017 compared with the cycles of the internal armed conflict during the same period. An observational study of ecological data panels, with aggregates at the national level, was conducted. Information from death certificates with HF as the basic cause of death (COD) was used. Variables of the year of death, sex, age, department of residence, and educational level were considered. Mortality rates adjusted for age were calculated. A joinpoint regression was used to model the trend of rates by educational level. We found that both men and women with primary education had the highest adjusted mortality rates: among men, RR_primary = 19.06 deaths/100,000 inhabitants, SE = 0.13 vs. RR_tertiary = 4.85, SE = 0.17, and similar differences among women. Mortality rates tended to decrease at all educational levels, with a greater reduction in people with higher educational levels. In both sexes, the behavior of the relative index of inequality showed significant inequality, albeit with a strong reduction during the last decade. Mortality due to HF in Colombia shows inequalities by educational level. In the prevention of HF, education should be considered a structural social determinant. In addition, we analyzed the potential role of the Colombian long-term armed conflict in the observed trends. We highlighted the role of the health sector, together with other sectors (education, work, and housing), in developing intersectoral public policies that contribute to the reduction of cardiovascular mortality disparities.

Introduction: Malaria is a disease with a high impact on Colombian population, which must be approached from the point of view of teamwork of institutions for knowledge exchange. Objective: To analyze the interactions of the Red de Gestión del Conocimiento, Investigación e Innovación en Malaria de Colombia. Materials and methods: An analysis of social networks was applied that allowed identifying the proximity between actors and the degree of knowledge between them. Indicators of density, diameter, average distance, and degree of centrality were observed. The documentary corpus for the study consisted of 193 technical documents published between 2016 and 2021, which were analyzed using text mining using the R programming language. The network was categorized based on five variables: comprehensive patient care, diagnosis, epidemiology and health information analysis systems, public policy and promotion and prevention. Results: The analysis of interactions indicated that the network was made up by 99 actors. The main interest in knowledge production was on epidemiology and health information analysis systems (98 % of the actors), followed by the integral patient care (80 % of the actors). On the contrary, the least approached category was malaria promotion and prevention practices (54 % of the actors). Conclusions: In general, this study contributes to the strengthening of key strategies in the dissemination of knowledge about malaria in Colombia.

Inequalities in dental prenatal control in Colombia: An analysis based on the IV National Oral Health Study, 2013-2014 / [Desigualdades en el control odontológico prenatal en Colombia, un análisis a partir del IV Estudio Nacional de Salud Bucal 2013-2014].

Introduction: Dental care is essential in guaranteeing the right to healthy motherhood. In Colombia, prenatal care policies incorporate the promotion, prevention, and care in oral health as part of the comprehensive care that pregnant women must receive within the health system. However, there is no systematic monitoring of compliance with these guidelines. Objective: To explore effective care and social inequalities in the provision and use of prenatal dental control in Colombia. Materials and methods: This was a descriptive study with data on pregnant women reported in the Fourth National Oral Health Study, 2013-2014. Absolute and relative social inequalities were estimated according to the area of residence, ethnicity, education level, health affiliation regime, and socioeconomic stratum. Results: We analyzed the data from 1,050 pregnant women. In total, 88.37% received prenatal control and 57.19%, dental control. We observed a general pattern of social gaps in the effective use of the latter, mainly due to the health insurance regime. The pregnant women with the greatest possibility of having some prenatal dental control, were those with some health insurance (prevalence ratio [RP]=2.62; CI 95%: 2.12-3.12), residents in urban areas (RP= 1,37; CI95%: 1.18-1.56), with higher and/or technical education level (RP=1.20; CI95%: 1.02-1.38) or from mid-high social strata (RP=1.15; CI95%: 1.01-1.29). Conclusions: In Colombia, the effective provision of dental control to pregnant women as part of comprehensive prenatal care continues to be a challenge. Significant efforts are required to comply with regulations and reduce social inequalities in access to this service.

Introducción. La atención odontológica es esencial para garantizar el derecho a una maternidad saludable. En Colombia, las políticas de atención prenatal incorporan la promoción, prevención y atención en salud bucal como parte de la atención integral que deben recibir las mujeres gestantes en el sistema de salud, sin embargo, no se hace un seguimiento sistemático del cumplimiento de estas directrices. Objetivo. Explorar la atención efectiva y las desigualdades sociales en la prestación y el uso del control odontológico prenatal en Colombia. Materiales y métodos. Estudio descriptivo con datos de las mujeres gestantes reportadas en el Cuarto Estudio Nacional de Salud Bucal, 2013-2014. Se estimaron las desigualdades sociales absolutas y relativas, según zona de residencia, pertenencia étnica, nivel educativo, régimen de afiliación a los servicios de salud y estrato socioeconómico. Resultados. Se analizaron los datos de 1.050 mujeres gestantes. El 88,37 % recibió control prenatal y, el 57,19 %, control odontológico. Se observó un patrón general de brechas sociales en el uso efectivo de este último servicio, principalmente en función del aseguramiento. Las mujeres gestantes con mayor posibilidad de recibir atención odontológica prenatal fueron aquellas con algún aseguramiento en salud (razón de prevalencias, RP=2,62; IC95% 2,12-3,12), residentes en zonas urbanas (RP=1,37; IC95% 1,18-1,56), con nivel educativo técnico o superior (RP=1,20; IC95% 1,02-1,38) o de estratos sociales medios o altos (RP=1,15; IC95% 1,01-1,29). Conclusiones. En Colombia, la prestación efectiva del control odontológico a mujeres gestantes como parte de la atención prenatal integral, sigue siendo un reto. Se requieren importantes esfuerzos para cumplir las normas y reducir las desigualdades sociales en el acceso a este servicio.

Resumen Objetivo: Describir el riesgo de transmisión y severidad de las variantes de preocupación Alpha y Gamma del SARS-CoV-2 en comparación con otras variantes. Materiales y métodos: Revisión rápida y narrativa de literatura realizada en PubMed hasta mayo 10 de 2021. Resultados: La búsqueda capturó 262 artículos, de los cuales se incluyeron 15 estudios. Cuatro fueron incluidos en el control de referencias. De los 19 estudios, 6 corresponden con literatura gris. La mayoría de los estudios analizaron la variante de preocupación Alpha, solo uno para Gamma. La variante de preocupación Alpha es consistente con mayor riesgo de transmisión (entre el 35 y 89 % mayor riesgo), de hospitalización (entre 64 y 234 % mayor riesgo) y de muerte (entre 36 y 140 % mayor riesgo) en comparación con otras variantes. La variante de preocupación Gamma reporta una posible correlación fuerte y positiva entre proporción positivos y las muertes (Rho 0,71; p <0,01). Conclusiones: Se encuentra más información de la variante de preocupación Alpha que de Gamma. La variante de preocupación Alpha reporta mayor riesgo de transmisión, hospitalización y muerte en comparación con otras variantes; pero estos resultados deben tomarse con precaución.

Abstract Objective: To describe the transmission and severity risk of the Alpha and Gamma variants concerning SARS-CoV-2 compared with other variants. Materials and methods: Narrative and rapid review conducted in PubMed up to May 10, 2021. Results: The search captured 262 articles, of which 15 studies were included. Four studies were included from the reference control. Six out of the 19 studies were gray literature. Most of the studies analyzed the variant of concern, Alpha, and only one for the Gamma variant. The variant of concern, Alpha, is consistent with a higher risk of transmission (between 35 and 89% higher risk), hospitalization (between 64 and 234% higher risk) and death (between 36 and 140% higher risk) compared to other variants. The Gamma variant reports a possible strong and positive correlation between positive proportions and deaths (Rho 0.71; p <0.01). Conclusions: There is more information regarding the variant of concern Alpha than Gamma. The variant of concern Alpha reports a higher risk of transmission, hospitalization, and death; but these results should be viewed with caution.

Hospitalization costs due to severe acute respiratory infection (SARI) in three Central American countries / Costos de hospitalización de infección respiratoria aguda grave (IRAG) en tres países de América Central

Objective: To estimate the direct medical costs of severe acute respiratory infection (SARI) in children and adults from three Central American countries with a bottom-up costing approach. Methods: The costs of inpatients treatment were estimated through the retrospective bottom-up costing in a randomized sample of clinical records from SARI patients treated in teaching tertiary hospitals during 2009 - 2011 period. Activities incurred per patient were registered and a setting-specific cost per activity was acquired. Average cost per patient in the group of children and elderly adults was estimated for each country. In Nicaragua, only the pediatric population was included. Costs were expressed in local currency (2011), American dollars, and international dollars (2005) for country comparison. Results: The care cost per case in children in Guatemala was the cheaper (I$971.95) compared to Nicaragua (I$1,431.96) and Honduras (I$1,761.29). In adults, the treatment cost for Guatemala was the more expensive: I$4,065.00 vs. I$2,707.91 in Honduras. Conclusion: Bottom-up costing of SARI cases allowed the mean estimates per treated case that could have external validity for the target population diagnosed in hospitals with similar epidemiological profiles and level of complexity for the study countries. This information is very relevant for the decision-making.

Objetivo: Estimar los costos directos de la atención de infección respiratoria aguda (IRAG) en niños y adultos en tres países de América Central. Métodos: Los costos de pacientes hospitalizados fueron estimados a través de análisis retrospectivo en una muestra aleatoria de registros de historias clínicas de casos de IRAG tratado en hospitales universitarios durante el periodo 2009-2011. Las actividades incurridas por paciente fueron registradas y un costo especifico para cada sitio fue estimado. El costo por cada niño y adulto mayor fue estimado para cada país. En Nicaragua sólo se incluyó población pediátrica. Los costos fueron expresados en moneda local (2011), dolar americano y dolar internacional (2005). Resultados: El costo por caso en niños en Guatemala fue el más barato (I$971.95) comparado al de Nicaragua (I$1,431.96) y Honduras (I$1,761.29). En adultos, el costo de tratamiento para Guatemala fue el más costoso: I$4,065.00 vs. I$2,707.91 en Honduras. Conclusión: Los costos de tratar casos IRAG estimados a partir de costos promedios pro caso pueden tener validez externa para hospitales con perfiles epidemiologicos similares y nivel de complejidad de atención para los países del estudio. Esta información es muy relevante para la toma de decisiones.

[Costs of Chagas' disease screening test in blood donors in two Colombian blood banks, 2015].

INTRODUCTION: Transfusion is a mechanism of transmission of Chagas' disease. There are no studies on the costs of the screening test in Colombian blood banks. OBJECTIVE: To estimate the costs of the screening test for Chagas' disease among blood donors in two Colombian blood banks, 2015. MATERIALS AND METHODS: We conducted a micro-costing study from the perspective of the health care provider to estimate the cost of Chagas' disease testing in two blood banks, Banco de Sangre de la Cruz Roja, Seccional Bolívar, and Banco de Sangre del Hospital de Yopal, Casanare, taking into account four cost categories: 1) Administrative costs: public services and insurance costs were calculated based on the blood bank area in square meters; 2) capital costs: building and equipment costs that were annualized using a 3% discount rate and a lifespan of 20 years for building and five for equipment; 3) costs of Chagas' disease test materials and reagents adjusted by blood bank production level, and 4) costs of staff in charge of Chagas' disease test processing. The costs of transfusion bagsand immunohematology tests are also reported. RESULTS: The cost of Chagas' disease test in the blood bank of Seccional Bolívar was COP$ 37,804 (USD$ 12), and the blood bag and immunohematology test costs were COP$ 25,941 (USD$ 8.2) and COP$ 6,800 (USD$ 2.2), respectively. In the blood bank of Yopal, Casanare, the costs were COP$ 77,384 (USD$ 24.6), COP$ 30,141 (USD$ 9.6) and COP$ 12,627 (USD$ 4), respectively. Personnel cost accounted for the highest percentage of the total cost for both blood banks (47.5% in Seccional Bolívar, and 55.7% in Yopal, Casanare). CONCLUSION: Our results are an important input for the planning of services and cost-effectiveness studies for screening tests for Chagas' disease in Colombian blood banks.

Individual and climate factors associated with acute respiratory infection in Colombian children.

The objective of this study was to examine the association between acute respiratory infection recall (ARI-recall) and individual and environmental factors such as climate, precipitation, and altitude above sea level in Colombian children. A secondary analysis of 11,483 Colombian children, whose mothers were interviewed in the 2010 National Demographic and Health Survey, was carried out. The outcome variable was the mother's or caregiver's ARI-recall. The independent variables were expressed at individual, cluster, and municipal levels. At the individual level, we considered health and individual characteristics of the children; at cluster level, we incorporated the altitude above sea level; and at the municipal level, we included precipitation and annual average climate. The association between ARI-recall and independent variables was assessed using a multilevel logistic regression model. ARI-recall was significantly associated with age (OR = 0.61; 95%CI: 0.48-0.79), belonging to an indigenous group (OR = 1.51; 95%CI: 1.16-1.96), and a medium or very poor wealth index (OR = 2.03; 95%CI: 1.25-3.30 and OR = 1.75; 95%CI: 1.08-2.84, respectively). We found interaction between acute child malnutrition and average annual precipitation. Children with acute malnutrition and from municipalities with high annual precipitation had significantly 3.6-fold increased risk of ARI-recall (OR = 3.6; 95%CI: 1.3-10.1). Individual conditions and precipitation are risk factors for ARI-recall in Colombian children. These results could be useful to understand ARI occurrence in children living in tropical countries with similar characteristics.

El objetivo del estudio fue examinar la asociación entre el historial de infección respiratoria aguda (IRA) y factores individuales y ambientales, tales como clima, precipitación y altitud por encima del nivel del mar en niños colombianos. Se realizó un análisis secundario de datos de 11.483 niños colombianos, cuyas madres fueron entrevistadas por la Encuesta Nacional de Demografía y Salud de 2010. La variable dependiente era el historial de IRA informado por la madre o cuidador(a). Las variables independientes se expresaron en el nivel individual, de clúster y municipal. En el nivel individual, consideramos las características individuales y de salud de los niños; en nivel de clúster, incorporamos la altitud sobre el nivel del mar y, en nivel municipal, incluimos la precipitación y el clima medio anual. La asociación entre el historial de IRA y las variables independientes se evaluaron con un modelo de regresión logística multinivel. El historial de IRA mostró una asociación significativa con la edad (OR = 0,61; IC95%: 0,48-0,79), pertenecer a un grupo indígena (OR = 1,51; IC95%: 1,16-1,96) y al estrato socioeconómico médio o muy bajo (OR = 2,03; IC95%: 1,25-3,30 y OR = 1,75; IC95%: 1,08-2,84, respectivamente). Identificamos una interacción entre la desnutrición infantil aguda y la precipitación anual promedio. Los niños con desnutrición aguda y aquellos de municipios con precipitaciones anuales altas mostraron un riesgo significativo 3,6 veces mayor de historial de IRA (OR = 3,6; IC95%: 1,3-10,1). Las condiciones individuales y la precipitación son factores de riesgo para el historial de IRA en niños colombianos. Los resultados pueden ser útiles para comprender la ocurrencia de IRA en niños que viven en países tropicales con características semejantes.

A história de IRA mostrou associação significativa com idade (OR = 0,61; IC95%: 0,48-0,79), pertencer a grupo indígena (OR = 1,51; IC95%: 1,16-1,96) e estrato socioeconômico médio ou muito baixo (OR = 2,03; IC95%: 1,25-3,30 e OR = 1,75; IC95%: 1,08-2,84, respectivamente). Identificamos interação entre desnutrição infantil aguda e precipitação anual média. As crianças com desnutrição aguda e aquelas de municípios com precipitação anual alta mostraram um risco significativo 3,6 vezes maior de história de IRA (OR = 3,6; IC95%: 1,3-10,1). As condições individuais e a precipitação são fatores de risco para história de IRA em crianças colombianas. Os resultados podem ser úteis para compreender a ocorrência de IRA em crianças vivendo em países tropicais com características semelhantes.

Global, Regional, and National Burden of Cardiovascular Diseases for 10 Causes, 1990 to 2015.

BACKGROUND: The burden of cardiovascular diseases (CVDs) remains unclear in many regions of the world. OBJECTIVES: The GBD (Global Burden of Disease) 2015 study integrated data on disease incidence, prevalence, and mortality to produce consistent, up-to-date estimates for cardiovascular burden. METHODS: CVD mortality was estimated from vital registration and verbal autopsy data. CVD prevalence was estimated using modeling software and data from health surveys, prospective cohorts, health system administrative data, and registries. Years lived with disability (YLD) were estimated by multiplying prevalence by disability weights. Years of life lost (YLL) were estimated by multiplying age-specific CVD deaths by a reference life expectancy. A sociodemographic index (SDI) was created for each location based on income per capita, educational attainment, and fertility. RESULTS: In 2015, there were an estimated 422.7 million cases of CVD (95% uncertainty interval: 415.53 to 427.87 million cases) and 17.92 million CVD deaths (95% uncertainty interval: 17.59 to 18.28 million CVD deaths). Declines in the age-standardized CVD death rate occurred between 1990 and 2015 in all high-income and some middle-income countries. Ischemic heart disease was the leading cause of CVD health lost globally, as well as in each world region, followed by stroke. As SDI increased beyond 0.25, the highest CVD mortality shifted from women to men. CVD mortality decreased sharply for both sexes in countries with an SDI >0.75. CONCLUSIONS: CVDs remain a major cause of health loss for all regions of the world. Sociodemographic change over the past 25 years has been associated with dramatic declines in CVD in regions with very high SDI, but only a gradual decrease or no change in most regions. Future updates of the GBD study can be used to guide policymakers who are focused on reducing the overall burden of noncommunicable disease and achieving specific global health targets for CVD.

Salud materna indígena en mujeres Nasa y Misak del Cauca, Colombia: tensiones, subordinación y diálogo intercultural entre dos sistemas médicos / Indigenous maternal health in women from Nasa and Misak ethnicities from Cauca, Colombia: tensions, subordination, and intercultural dialogue between two medical systems

Resumen En este texto se pretende avanzar en la comprensión de los elementos que configuran la relación entre madres Nasa y Misak del Cauca y los servicios de salud materna tradicional y occidental, desde un abordaje cualitativo que armonizó el modelo de construcción de sentido y la teoría fundamentada. Se identificó la forma cómo cada sistema médico define la salud, la enfermedad y la maternidad, que está reflejada en las prácticas y cuidados, siendo el parto el momento de mayores tensiones. Se han identificado patrones de relacionamiento entre los dos agentes del sistema médico. El sistema médico tradicional con bajo desarrollo propio y pérdida progresiva de valores culturales, así como el sistema médico occidental con la ausencia de servicios de salud apropiados culturalmente, dejan a las madres en un espacio de incertidumbre en el que no es posible realizar las prácticas tradicionales, ni acceder a los servicios propuestos por el sistema médico occidental.

Abstract This study sought to understand the components of the relationship between mothers from Nasa and Misak ethnicities from Cauca, Colombia, and both the indigenous and Western health care services for maternal health, through qualitative approach harmonizing the model of construction of meaning and grounded theory. Elements about health, illness and motherhood conceptualization inside each system were rescued. These elements are expressed in care practices, being the labor the moment of greatest tension. Patterns of relationships between actors of both medical systems were also identified. An indigenous health system with low development and progressive loss of values, in conjunction with a Western medical system without culturally appropriate health services, results in mothers in an environment of uncertainty where it is not possible to carry out traditional practices, nor having access to proper allopathic services.

Dengue mortality in Colombia, 1985-2012.

INTRODUCTION: Dengue in Colombia is an important public health problem due to the huge economic and social costs it has caused, especially during the disease outbreaks.  OBJECTIVE: To describe the behavior of dengue mortality in Colombia between 1985 and 2012.  MATERIALS AND METHODS: We conducted a descriptive study. Information was obtained from mortality and population projection databases provided by the Departamento Administrativo Nacional de Estadística (DANE) for the 1985-2012 period. Mortality rates, rate ratios, and case fatality rates were estimated.  RESULTS: A total of 1,990 dengue deaths were registered during this period in Colombia. Dengue mortality rates presented an increasing trend with statistical significance between 1985 and 1998. Higher mortality rates were reported in men both younger than 5 years and older than 65 years. Between 1995 and 2012, category 1 to 4 municipalities reported the highest mortality rates. Case fatality rates varied during the period between 0.01% and 0.39%.  CONCLUSION: Dengue is an avoidable disease that should disappear from mortality statistics as a cause of death. The event is avoidable if the proposed activities from the Estrategia de Gestión Integrada (EGI)-Dengue are implemented and evaluated. We recommend encouraging the development of an informational culture to contribute to decision making and prioritizing resource allocation.

Análisis exploratorio de ondículas de los patrones de estacionalidad del dengue en Colombia / Exploratory wavelet analysis of dengue seasonal patterns in Colombia

Introducción. El dengue tiene un comportamiento estacional asociado a los cambios climáticos, los ciclos del vector, los serotipos circulantes y las dinámicas poblacionales. El análisis de ondículas permite descomponer una serie de tiempo muy larga en sus componentes de tiempo calendario y periodo. Esta es la primera vez que se utiliza esta técnica para generar un modelo exploratorio del comportamiento del dengue en Colombia. Objetivo. Examinar los patrones de estacionalidad interanual del dengue en Colombia, en particular en los cinco municipios más endémicos, para el periodo 2007 a 2012, y de los ciclos entre años entre 1978 y 2013 a nivel nacional. Materiales y métodos. Se hizo un análisis exploratorio de ondículas con base en los datos de los casos incidentes de dengue reportados por semana epidemiológica en el periodo de 2007 a 2012, y por año, en el periodo de 1978 a 2013. Se utilizó un modelo autorregresivo de primer orden como hipótesis nula. Resultados. Fue evidente el efecto de la epidemia de 2010 sobre la serie de tiempo a nivel nacional y la de los cinco municipios. Se observaron diferencias en los patrones de estacionalidad interanual por municipio. Asimismo, a nivel nacional se hallaron ciclos de dos a cinco años desde el 2004. Conclusiones. El análisis de ondícula permite estudiar una serie de tiempo larga con patrones de estacionalidad variables, como en el caso del dengue en Colombia, e identificar diferencias por regiones. Es necesario explorar estos patrones en niveles de agregación inferiores y evaluar su relación con diversas variables predictoras.

Introduction: Dengue has a seasonal behavior associated with climatic changes, vector cycles, circulating serotypes, and population dynamics. The wavelet analysis makes it possible to separate a very long time series into calendar time and periods. This is the first time this technique is used in an exploratory manner to model the behavior of dengue in Colombia. Objective: To explore the annual seasonal dengue patterns in Colombia and in its five most endemic municipalities for the period 2007 to 2012, and for roughly annual cycles between 1978 and 2013 at the national level. Materials and methods: We made an exploratory wavelet analysis using data from all incident cases of dengue per epidemiological week for the period 2007 to 2012, and per year for 1978 to 2013. We used a first-order autoregressive model as the null hypothesis. Results: The effect of the 2010 epidemic was evident in both the national time series and the series for the five municipalities. Differences in interannual seasonal patterns were observed among municipalities. In addition, we identified roughly annual cycles of 2 to 5 years since 2004 at a national level. Conclusions: Wavelet analysis is useful to study a long time series containing changing seasonal patterns, as is the case of dengue in Colombia, and to identify differences among regions. These patterns need to be explored at smaller aggregate levels, and their relationships with different predictive variables need to be investigated.

Comportamiento de la mortalidad por dengue en Colombia entre 1985 y 2012 / Dengue mortality in Colombia, 1985-2012

Introducción. El dengue en Colombia es un importante problema de salud pública debido a las enormes pérdidas económicas y sociales que ha provocado, especialmente durante los picos epidémicos. Objetivo. Describir el comportamiento de la mortalidad por dengue en Colombia entre 1985 y 2012. Materiales y métodos. Se hizo un estudio descriptivo. La información se obtuvo de las bases de datos de mortalidad y de las proyecciones de población de 1985 a 2012 del Departamento Administrativo Nacional de Estadística (DANE). Se estimaron tasas de mortalidad, razón de tasas y letalidad. Resultados. Se registraron 1.990 muertes por dengue durante el periodo señalado. Las tasas de mortalidad por dengue aumentaron entre 1985 y 1998. Las tasas más altas se presentaron en hombres menores de 5 años y de 65 o más años de edad. Entre 1995 y 2012 los municipios de categorías 1 a 4 también presentaron las tasas más altas. La letalidad durante el periodo varió entre 0,01 y 0,39 %. Conclusión. El dengue es una enfermedad evitable que debería desaparecer de las estadísticas de mortalidad como causa de defunción. La muerte es evitable en la medida en que se implementen y evalúen las actividades propuestas en la Estrategia de Gestión Integrada (EGI)-Dengue. Se recomienda impulsar el desarrollo de una cultura informática que contribuya a la toma de decisiones y a priorizar la utilización de los recursos asignados.
