Item Assessment of pesticide residues in processed foods in Chile(2011) Castillo, Cecilia; Rivas, Cecilia; Fuentes, Rodrigo; Pérez Santiago, Omar; Tur Mari, Josep A.Introduction: Pesticides can be present in food as a secondary waste treatment of the crops or contain high levels as a result of pollution. They produce public benefit by increasing agricultural productivity but also determine risks to human health. Objective: To identify in a processed food sample based on fruits, vegetables and/or cereals ingredient the presence of pesticide residues and review these results in relation with the limits allowed in the chilean and the European Economic Community food regulations. Methods: In a convenience sample of processed foods made with fruits, vegetables and/or cereal ingredients: two samples of orange juices, two samples of infant foods based on cereals, five based on vegetables or fruits and one product based on cereals and vegetables, we tested the presence of pesticide residues using for assessing a multiresidue methods. Results: Five samples showed pesticides residue. Carbaryl was found in one sample of orange juice (0.01 mg/kg), lprodione in three food samples: plum and raisins, multi-fruit and peach mush (0.04; 0,01 and 0.08 mg/kg respectively) and pirimiphos-methyl (0.02 mg/kg) was found in the of asparagus soup. Conclusion: Although the sample is not representative of the uiverse of the Chilean processed food, these results suggest the need to establish a surveillance system to ensure the safety of processed foods, especially in children, and define the maximum residue levels allowed in this kind of foodItem Case−Control Study of Risk Factors for Meningococcal Disease in Chile(Centers for Disease Control and Prevention, 2017) Olea, Andrea; Matute, Isabel; Gonzalez, Claudia; Delgado, Iris; Poffald, Lucy; Pedroni, Elena; Alfaro, Tania; Hirmas, Macarena; Nájera, Manuel; Gormaz, Ana; Lopez, Dario; Sergio, Loayza; Ferreccio, Catterina; Gallegos, Doris; Fuentes, Rodrigo; Vial, Pablo; Aguilera, XimenaAn outbreak of meningococcal disease with a case-fatality rate of 30% and caused by predominantly serogroup W of Neisseria meningitidis began in Chile in 2012. This outbreak required a case−control study to assess determinants and risk factors for infection. We identified confirmed cases during January 2012−March 2013 and selected controls by random sampling of the population, matched for age and sex, resulting in 135 case-patients and 618 controls. Sociodemographic variables, habits, and previous illnesses were studied. Analyses yielded adjusted odds ratios as estimators of the probability of disease development. Results indicated that conditions of social vulnerability, such as low income and overcrowding, as well as familial history of this disease and clinical histories, especially chronic diseases and hospitalization for respiratory conditions, increased the probability of illness. Findings should contribute to direction of intersectoral public policies toward a highly vulnerable social group to enable them to improve their living conditions and health.Item Estructura y funcionamiento del sistema de salud chileno. Serie de Salud Poblacional N°2(Universidad del Desarrollo, 2019) Aguilera, Ximena; Castillo, Carla; Covarrubias, Trinidad; Delgado, Iris; Fuentes, Rodrigo; Gómez, María Inés; González, Claudia; Hirmas, Macarena; Matute, Isabel; Olea, Andrea; Quiroga, Anita; Urrejola, Oscar; Soto, Marco; Aguilera, Ximena; Castillo, Carla; Covarrubias, Trinidad; Delgado, Iris; Fuentes, Rodrigo; Gómez, María Inés; González, Claudia; Hirmas, Macarena; Matute, Isabel; Olea, Andrea; Quiroga, Anita; Urrejola, Oscar; Soto, MarcoCon este documento ponemos a su disposición la segunda publicación de la serie Salud Poblacional del Centro de Epidemiología y Políticas de Salud, dedicada en esta oportunidad a entregar una visión global sobre la estructura, organización y funcionamiento del sistema de salud chileno, como una herramienta que permita a los estudiantes comprender su estructura, funciones y complejas interrelaciones.Publication Quemaduras: ¿por qué prestarles especial atención a los adolescentes en América Latina y El Caribe desde un enfoque de prevención primaria en salud?(2023) Blukacz, Alice; Cabieses, Báltica; Obach, Alexandra; Fuentes, Rodrigo; Carmina, Domic; Peredes, Carola; Saavedra, Rolando; Rojas, JorgeLa evidencia existente en materia de quemaduras en población menor de edad a nivel global se ha enfocado principalmente en niños y niñas menores de 10 años, dejando atrás al grupo etario definido como "adolescente" por la Organización Mundial de la Salud. Sin embargo, la etapa de la adolescencia presenta características propias que la diferencian de los rangos etarios menores con respecto a las quemaduras. Estas diferencias son relevantes desde una perspectiva de prevención primaria, la cual se centra en evitar la enfermedad o lesión. En este contexto, el presente artículo reflexiona en torno a los motivos por los cuales es necesario prestarles especial atención a las y los adolescentes en el marco de la prevención primaria de las quemaduras, con relevancia para Latinoamérica y El Caribe. Primero, los escenarios de quemaduras en adolescentes muchas veces se vinculan con la participación en actividades de riesgo por presión, deseabilidad social o baja percepción de los riesgos asociados. Segundo, es importante recalcar que los adolescentes pueden experimentar vulnerabilidad social, la cual los puede exponer al riesgo de sufrir una quemadura intencional o no. Tercero, el riesgo de quemaduras en adolescentes se puede asociar con la salud mental y escenarios de autolesión. Se requiere indagar en estos aspectos, tanto a través de estudios cuantitativos epidemiológicos como de estudios cualitativos, para poder diseñar e implementar estrategias de prevención primarias relevantes para este grupo de población en la región.Item Trends and correlates of cystic echinococcosis in Chile: 2001–2012(PLoS, 2017) Colombe, Soledad; Togami, Eri; Gelaw, Fkadu; Antillon, Marina; Fuentes, Rodrigo; Weinberger, DanielEchinococcosis is a neglected zoonotic disease affecting over 1 million people worldwide at any given time. It is the leading cause of hospital admissions for parasitic diseases in Chile. We conducted a retrospective investigation of hospitalized cases to describe the epidemiological trends of echinococcosis in Chile. We also examined the potential environmental risk factors for echinococcosis hospitalization rates. Through nation-wide hospital discharge data, a total of 11,516 hospitalized patients with cystic echinococcosis were identified between January 2001 and December 2012. The mean age of hospitalization was 40 years, with notable gender difference in pediatric patients. The hospitalization rate was found to be overall steadily decreasing from 2001 (7.02 per 100,000) to 2012 (4.53 per 100,000) with a 5% decrease per year (rate ratio = 0.95 [95% CI: 0.94, 0.96]). The hospitalization rate was higher in the south of Chile compared to the north. Goat density and intermediate precipitation were found to be significantly positively associated with the hospitalization rate while annual average temperature was found to be significantly negatively associated with the hospitalization rate. Findings of this study indicate that echinococcosis is still an important public health burden in Chile related to interaction with livestock and climate. Efforts should be placed on targeted prevention measures for farmers and raising awareness of echinococcosis among health care workers.
