BackgroundCommunity integration in dengue control requires assessments of knowledge, attitudes and practices (KAPs), which can vary widely according to demographic and educational factors. We aimed to describe and compare the KAPs according to level of education in municipalities in the Caribbean region of Colombia.MethodsA survey was administered from October to December 2015, including families selected through probabilistic sampling in eleven municipalities. The analysis focused on the comparative description of the responses according to level of education. The KAP prevalence ratios (PR) according to education were estimated using Poisson regression (robust), including age and sex as adjustment variables.ResultsOut of 1057 participants, 1054 (99.7%) surveys were available for analysis, including 614 (58.3%) who had a high school level of education or higher and 440 (41.7%) who had a lower level of education (not high school graduates). The high school graduates showed a higher frequency of correct answers in relation to knowledge about dengue symptoms and transmission.On the other hand, graduates showed a higher probability of practices and attitudes that favor dengue control, including not storing water in containers (PR: 2.2; 95% Confidence Interval [CI]: 1.42–3.43), attend community meetings (PR: 1.33; 95% CI: 1.07–1.65), educate family members and neighbors in prevention measures (PR: 1.35; 95% CI: 1.15–1.59).ConclusionsLevel of education could be a key determinant of knowledge of the disease and its transmission, as well as attitudes and practices, especially those that involve the integration of community efforts for dengue control.

Results from the present study showed that haemophilia was associated with a higher frequency of LBMD. Severity of haemophilia, haemophilic arthropathy, and elevated C-reactive protein levels was directly associated with LBMD.

BackgroundThe increasing burden associated with dengue in Latin America makes it essential to understand the community’s interest in acquiring vaccines, as an input to plan its introduction in endemic regions. The objective of this study is to learn the felt demand for dengue vaccines by estimating the willingness to pay and its associated factors in endemic communities of the North Caribbean region of Colombia.MethodsA population survey was administered from October to December 2015, including 1037 families in 11 municipalities in Colombia. One adult per family was interviewed on their perception and history of dengue. Participants received a description of four hypothetical scenarios of dengue vaccines, administered in a single dose or in 3 doses, with an effectiveness of 70% for 5 years or 95% for 30 years. The willingness to pay for each one of these vaccines was inquired vs. 5 hypothetical prices in Colombian pesos.ResultsMost participants recognized dengue as a serious disease in children (99.3%) and adults (98.6%). 33 (3.2%) of the total respondents reported having suffered dengue and 19 (57.6%) of them required hospitalization. The price of the vaccine was inversely related to the willingness to pay. In addition, single dose vaccines (compared to 3 doses) and one with a protection of 95% for 30 years (compared to an effectiveness of 70% for 5 years), were associated with greater willingness to pay. Greater willingness to pay was observed among the respondents who considered it likely to get the disease, either themselves (OR 1.56; CI 95% 1.08–2.26) or their children (OR 1.89; CI 95% 1.28–2.81), in the next 5 years. The participants who have been diagnosed with dengue also showed greater willingness to pay (OR 1.89; CI 95% 1.01–3.54) compared to those who did not have this history.ConclusionFactors such as price, number of doses and effectiveness can independently influence the decision to purchase a vaccine against an endemic disease, such as dengue. Additionally, this study reveals that background and perceptions of the disease can affect individuals’ interest in acquiring this type of preventive interventions.

RESUMENLa investigación biomédica enfocada a la preservación de la salud y manejo de la enfermedad requiere hoy del trabajo articulado bidireccional entre básicos y clínicos, lo cual ha generado una nueva tendencia, denominada investigación traslacional. Este tipo de investigación se fundamenta en poder brindar una atención en salud oportuna, pertinente, eficaz y personalizada, para lo cual se requieren muestras biológicas e información clínica asociada, garantizando a su vez seguridad, calidad y confidencialidad para los donantes. Promover la investigación traslacional y la aplicación de los avances del conocimiento y de la tecnología derivados de la investigación y la innovación, requiere del apoyo de infraestructuras de fácil acceso que faciliten la rápida demostración experimental de una hipótesis o la comprobación de un modelo simulado previamente. Dentro de las diversas plataformas biomédicas y de salud existentes, los Biobancos, en sus diferentes modalidades, se constituyen en una de las más atractivas plataformas a la hora de contribuir a establecer puentes entre la investigación básica y clínica, con la práctica asistencial. La necesidad de contar con muestras biológicas humanas de alta calidad y, al mismo tiempo, la obligación de preservar los derechos de los donantes, ha elevado la gestión de los Biobancos a la categoría de disciplina científico-técnica, con una complejidad particular que involucra múltiples aspectos entre los cuales se incluyen aspectos científicos, técnicos, éticos, jurídicos y sociales. Esta serie de artículos, que serán publicados en los diferentes números de la revista durante el 2016, tienen como objetivo hacer una revisión crítica de los aspectos más relevantes en torno a la gestión de los Biobancos con fines de investigación y proponer una serie de guías de manejo del material biológico humano a conservar las cuales se han desarrollado en el marco del Programa Cardiecol.
