Introduction:Dengue is the most widespread arbovirus worldwide. In Paraguay, it reappeared in [1988][1989], with one of the largest epidemic outbreaks occurring in 2011. Objective: To evaluate the performance of the dengue epidemiological surveillance system in Paraguay between 2009 and 2011. Materials and methods:We conducted an ecological study with secondary epidemiological surveillance data. We analyzed notified cases of the disease based on the distribution expected by Benford's law. To this end, we used the first and second digits from the global records stratified by region, season, population density, indicators of housing conditions and heads of cattle. Results: The epidemiological surveillance system performed better during non-epidemic periods and in the states with better housing conditions and fewer heads of cattle. Conclusion: Given that a difference in the performance existed, we recommended that the system remains operating at the same high alert level even during periods when fewer cases are expected. The technology used by the method proposed to monitor the notification of cases is easy to transfer to operational staff. Materiales y métodos. Se hizo un estudio ecológico basado en datos secundarios de la vigilancia epidemiológica. Con base en la distribución esperada según la ley de Benford, se analizaron los casos notificados de la enfermedad; para tal fin, se usaron los primeros y segundos dígitos de los registros globales y estratificados por regiones, estaciones, densidad poblacional, indicadores de las condiciones de la vivienda y número de cabezas de ganado bovino. Resultados. El sistema de vigilancia epidemiológica se desempeñó mejor durante los periodos no epidémicos, y en los departamentos donde existen mejores condiciones de vivienda y pocas cabezas de ganado bovino.584 Biomédica 2016;36:583-92 Gómez-Camponovo M, Moreno J, Idrovo ÁJ, et al. Conclusión. Dadas las diferencias de desempeño, se recomendó que el sistema mantenga la alerta incluso cuando no se espere un mayor número de casos. El método propuesto para evaluar la notificación de casos es fácil de transferir al personal operativo.Palabras clave: control de vectores; notificación de enfermedad; vigilancia epidemiológica; dengue; distribuciones estadísticas; Paraguay. doi: http://dx

Esta pesquisa teve como objetivos identificar os grupos de usuários segundo o grau de satisfação com a atenção recebida nos Módulos Gerontológicos e determinar os principais fatores associados. Trata-se de estudo transversal realizado com 181 usuários nos 36 módulos do Seguro Social dos Trabalhadores Públicos, no México. O nível de satisfação foi avaliado segundo três aspectos: características gerais da atenção recebida, amabilidade no trato e infraestrutura. Foi realizada uma análise de conglomerados para identificar grupos de usuários segundo o grau de satisfação e um modelo de regressão logística ordinal para identificar os fatores associados. Estiveram satisfeitos com o serviço 53% dos usuários; medianamente satisfeitos, 34,3%; e insatisfeitos, 12,7%. Os principais fatores associados com maior grau de satisfação foram: ser mulher, maior idade e ser chefe/a de família. O sistema de saúde deve dirigir sua atenção para esse grupo populacional que é crescente e incentivar o desenvolvimento de uma atenção de qualidade que contemple as suas necessidades.

The objective of this study was to predict chloroform formation resulting from the process of disinfecting water, particularly trihalomethane which is most frequently produced. A statistical model was used which included repeated measurements of water parameters used for monitoring water quality at 51 sites covering the municipal water system of Montevideo. Samples were taken considering different seasons from June 2009 to July 2011 in Montevideo. Total samples (n = 330) were analytically studied using the headspace-gas chromatography method coupled with mass spectrometry. Chloroform was the dependent variable and the covariables were pH, temperature, free chlorine, and total chlorine. A Tobit analysis with an unstructured correlation matrix was performed, and a significant interaction was found between pH and free chlorine for the prediction of chloroform formation. We concluded that parameters for the continuous control of water quality for consumption can be used to predict the levels of chloroform that may be present. Given the large measurement to variability found in the repeated measurements, the use of averages that include more than one season is not recommended to determine the degree of compliance with acceptable levels established by norms.

Uruguay is in South America. It has 3,286,314 inhabitants, 1.6% of which lacks comprehensive health insurance. Detected cases of COVID-19 represent 0.022% of the population, 2.6% of which has resulted in death. Mortality from this illness is 0.6% per 100,000 inhabitants, and health workers represent 14% of detected cases. The country is slowly coming out of intensified social distancing. This article reports on accumulated, recovered, and active cases.  The authors also frame the causes of this zoonosis in terms of an environmental health problem, and thus a global health problem, requiring a “one health” approach. Human activity has changed natural habitats as a result of extraction activities, increased urbanization, growing populations, different cultural practices, and socio-economic conditions. This contributes to the emergence of zoonoses, particularly RNA viruses.  If the cause of this phenomenon is not addressed, we will continue to face increasingly greater challenges.
