A serological survey was carried out in Monteria (500 000 population), a mid-size city in Colombia. An overall prevalence of 55.3% (95% confidence interval, 52.5%–57.8%) was found among a sample of 1.368 people randomly selected from the population. Test positivity was related to economic characteristics with the highest prevalence found in the most impoverished areas, representing 83.8% of the city's population. We found a prevalence that might be associated with some important level of population immunity. [ABSTRACT FROM AUTHOR]

- Abstract
Objective. To economically estimate health Research in Colombia, partially financed by Colciencias starting from the administration of the Fund for Research in Health (FRH) 2001 - 2005. Materials and methods. An economic valuation was conducted from perspective of the society and the State, considering intermediate results for which two scenarios were adopted (maximum and minimum). Results. 338 projects were reviewed (48.7% financed by Colciencias). The mean cost per project was 287 millions. The growth of resources for project contributed by the FRH was of 75% in real terms and the financing ratio Colciencias / counter part, increased from 0.8 in 2001 to 1.1 in 2005. The department with greatest participation was Antioquia (30.2%), which through 2005 had concluded 57 (16.8%) with a cost of 8.889 million (9.7%). As products, the following stands out: 30 articles submitted to national journals and 35 submitted to international journals, 69 participations in congresses, and the training of four doctors and 24 Masters of Sciences. The formation of human talent represents more than 95% percent of the benefits. The benefitcost ratio oscillates between 4.72 and 6.34 (for each monetary unit invested in health research more than six times that investment is generated for society). Conclusions. The economic valuation highlights the important fact that, in the execution of research projects, researchers are trained, in front of the high returns that this implies. For this reason, Colciencias can strengthen the valuation of its funde, Objetivo. Valorar económicamente la investigación en salud en Colombia, financiada parcialmente por Colciencias a partir de la gestión del Fondo para la Investigación en Salud (FIS) 2001 � 2005. Materiales y métodos. Se realizó una valoración económica desde la perspectiva de la sociedad y el Estado teniendo en cuenta resultados intermedios, para los que se adoptaron dos escenarios (máximo y mínimo). Resultados. Se revisaron 338 proyectos (48.7% financiado por Conciencias). El costo medio de los proyectos fue 287 millones. El crecimiento de recursos por proyecto aportados por el FIS fue del 75% en términos reales y la razón de financiación Colciencias/contrapartida, pasó de 0.8 en 2001 a 1.1 en 2005. Antioquia fue el departamento con mayor participación (30.2%). A 2005 habían finalizado 57 (16.8%) con un costo de 8.889 millones (9.7%). Como productos se destacan 30 artículos sometidos en revistas nacionales y 35 en internacionales, 69 participaciones en congresos y la formación de 4 doctores y 24 magísteres. La formación de talento humano representa más del 95% por ciento de los beneficios. La razón beneficio/costo oscila entre 4.72 y 6.34 (por cada peso invertido en investigación en salud se generan, para la sociedad, más de seis veces dicha inversión). Conclusiones. La valoración económica destaca la importancia que en la ejecución de los proyectos de investigación se formen investigadores, frente a los altos retornos que ello implica. Por ello, debe consolidarse, por parte de Colciencias, como criterio de valoración positiva de un proyecto de investigación, el hecho de proponer la formación de investigadores.

Objetivo: Evaluar la prevalencia de algunos factores de riesgo cardiovasculares en población escolarizada de Barranquilla (Colombia). Material y métodos: estudio descriptivo transversal en 516 escolares de 6 a 17 años pertenecientes a escuelas públicas y privadas inscritas en la secretaria de educación distrital de la ciudad de Barranquilla; se evaluaron presión arterial e índice de masa corporal. Se trabajo con las definiciones de HTA del 4to reporte de diagnostico, evaluación y tratamiento de presión arterial elevada en niños y adolescentes del NHBPEP y de la Obesidad de la OMS. Resultados: La prevalencia global de PAD elevada fue de 7,3%. La prevalencia de PAD elevada en el sexo masculino fue de 7,8% mientras que en el sexo femenino fue de 6,6% (p=0,6). Por edades, fue más alta en el grupo etáreo en riesgo 14- 17 años con un 3,1%(p=0,5). Las personas con antecedentes paternos de HTA tuvieron una prevalencia de 15,7% que era significativamente más alta que en personas sin ese antecedente. (p=0,032). La prevalencia de obesidad en el sexo masculino fue de 7,8% y entre el sexo femenino fue de 6,0%(p=0,4). Conclusiones: existe una elevada prevalencia de PAD y PAS elevada así como de obesidad principalmente en los escolares varones, la asociación de PAD elevada con el antecedente familiar de hipertensión en el padre sigue siendo significativa después de ajustar por sexo, lo cual sugiere que es necesario continuar realizando investigaciones relacionadas con hipertensión arterial y sus factores asociados con el fin de plantear y ejecutar estrategias de soluciones efectivas que controlen la ocurrencia de estos eventos y los eviten en edades más tempranas. / Abstract. Objective: To evaluate the prevalence of cardiovascular risk factors in school population from Barranquilla (Colombia). Methods: Descriptive cross-sectional study in 516 schoolchildren aged 6 to 17 years old belonging to public and private schools registered with the secretary of education district of Barranquilla city, blood pressure and body mass index were assessed. It has been worked with the definitions of hypertension 4th report of diagnosis, evaluation and treatment of high blood pressure in children and adolescents of NHBPEP and WHO Obesity. Results: The overall prevalence of PAD was 7.3% higher. The high prevalence of PAD in males was 7.8% while in females was 6.6% (p = 0.6). By age, was higher in the age group at risk 14 to 17 years old with a 3.1% (p = 0.5). People with parental history of hypertension had a prevalence of 15.7% which was significantly higher than in people without that background. (p = 0.032). The prevalence of obesity in males was 7.8% and among females was 6.0% (p = 0.4). Conclusions: There is a high prevalence of elevated SBP and DBP and obesity among school children mainly boys, the association of elevated DBP with family history of hypertension in the father is still significant after adjusting for sex, suggesting the need to continue conducting research related to hypertension and its associated factors in order to raise and implement strategies for effective solutions to control the occurrence of these events and avoided in younger age.

- Abstract
During the pandemic, Latin American countries suffered the collapse of their health systems. This was caused by the high demand for care of patients infected with SARS-CoV-2, which was added to the care of patients with other diseases. The significant increase in demand for health services caused medical and laboratory supplies to decline rapidly. The COVID-19 pandemic exacerbated a health crisis in several developing countries, mainly caused by insufficient systematic policies for integrating scientific knowledge. The current Colombian government must formulate a Biotechnological or Biosecurity Sovereignty Law that guarantees scientific autonomy, ensuring that Colombia is self-sufficient in Science, Technology, and Innovation. Colombian government should also focus on establishing and developing pharmaceutical chemical production by acquiring active chemical ingredients from other countries. This strategy could reduce the production costs and final prices of medicines, as well as generate high-level employment and wealth for the country. In this way, the Colombian government could prevent shortage of essential medicines and excessive price increases by commercial intermediation. In conclusion, the manuscript focuses on the lack of biotechnological sovereignty in Colombia. We propose a model of a Latin American Science and Technology ecosystem to achieve biotechnological sovereignty via state funding of research, strengthening universities, and fostering participation among private companies and Ministries of Science, Education, Trade, and Health. Scientific autonomy based on innovative processes that strengthen biotechnological independence can contribute to the economy by generating gross added value, creating high-quality employment, and facilitating the appropriation and social dissemination of knowledge, and cost reduction.
