Abstract: The aim of this study was to evaluate the design and implementation of the Information System for Cervical Cancer Detection Program in Women in the Institute for Social Security and Services for State Workers. We performed a retrospective study applying the framework and tools for Performance Routine Information System Management (PRISM). A sample of 38 subjects was interviewed in 13 health facilities. The information system’s evaluation showed an overall performance of 73.7% at the beginning of 2017. The improvement between versions was mainly observed in the quality of the data (64.6% vs 72.5%), while the use of the information was very similar (78.6% vs 78.9%). We concluded that this information system provides good information to follow-up and control of its beneficiary population. However, there is an opportunity to improve health staff training, also new indicators for health outcomes are required.

Objectives Identify the changes in some physiological and microbiological parameters in the saliva from a group of women during and after their pregnancies. Methods Stimulated whole saliva was collected from a cohort of 35 women during their pregnancy and afterwards to determine each sample's physicochemical (secretion rate, pH and buffer capacity) and microbiological characteristics (acidogenic bacteria count). Results The pH and buffer capacity of saliva during pregnancy were lower than after pregnancy. There were no statistically significant changes regarding S. mutans and Lactobacillus spp. count, but a tendency towards increased values during pregnancy was noted. Conclusions Changes occurring in the saliva of pregnant women can lead to an increase of risk of suffering disease affecting one's oral health, such as caries, gingivitis and periodontal disease; this could be prevented by appropriate diagnosis and dental follow-up, including education regarding pregnant women's oral health.

Objetivo Identificar las variaciones producidas en algunos parámetros fisicoquímicos y microbiológicos de la saliva en un grupo de mujeres durante y después de la gestación. Materiales y Métodos Se recolectó saliva total estimulada en una cohorte de 35 mujeres embarazadas y después del parto. A cada muestra le fueron determinadas características fisicoquímicas (tasa de secreción, pH y capacidad amortiguadora) y microbiológicas (recuentos de bacterias acidogénicas). Resultados El pH y la capacidad amortiguadora de la saliva durante el embarazo fueron más bajos que en el posparto, mientras que la tasa de secreción salival fue más alta en el embarazo. Los recuentos de S. mutans y Lactobacillus spp. no presentaron cambios significativos estadísticamente, pero se observa una tendencia al aumento en los recuentos durante la gestación. Conclusión Los cambios ocurridos en la saliva de las gestantes pueden llevar a un aumento del riesgo de aparición de enfermedades bucales como caries, gingivitis y enfermedad periodontal, los cuales podrían disminuirse, mediante un adecuado diagnóstico y seguimiento odontológico, que incluya educación en salud oral a la gestante.

Introduction: Population ageing is a main concern under the biosanitary point of view. Aim: To assess the nutritional status of people 65 year-old and older in Cantabria (Spain) Method: A total of 1605 persons were studied by means of the MNA (Mini Nutritional Assessment); a) by primary care (59.9% in the unit, and 4.7% at home) and, b) in nursing homes (35.4%). Results: Nutritional score (NS) was 23.4 ± 4.1 for women and 24.4 ± 4 in males (p < 0.001). We emphasize the fact that 22.3% of people studied in the nursing homes were malnourished or at risk of malnutrition, compared with 14.2% of those studied at the unit, and only 3.3% of the home visited elders. The correlation between the value of the NS and the subjective estimation of nutrition status showed a high value (0.65). We emphasize the negative correlation (-0.53) between BNI value and the incidence of skin lesions. Conclusion: Our results highlight the importance of identifying malnutrition or its risk in elders in order to prevent the negative consequences of this deficiency.

Introducción: El envejecimiento de la población representa uno de los retos más importantes desde el punto de vista biosanitario. Objetivo: Valorar el estado nutricional de las personas de 65 y más años de Cantabria. Métodos: Un total de 1605 personas fueron evaluadas por medio del MNA; a) en atención primaria (59,9% en la consulta y 4,7% en domicilios) y, b) en residencias de ancianos (35,4%). Resultados: La puntuación nutricional (PN) obtenida de la suma de los ítems del MNA fue 23,4 ± 4,1 para las mujeres y 24,4 ± 4 en los varones (p < 0,001). Destaca el hecho de que el 22,3% de las personas estudiadas en residencias está malnutrida o en riesgo de malnutrición, frente al 14,2% de las que acuden a consulta, y sólo el 3,3% de las estudiadas en su domicilio. La correlación entre los valores de la PN y la apreciación subjetiva del estado de nutrición mostró un valor elevado (0,65). Destacamos la correlación negativa (-0,53) entre los valores del IMC y la incidencia de lesiones cutáneas. Conclusiones: Nuestros resultados indican la importancia de la identificación de la desnutrición o su riesgo, en personas mayores, por las consecuencias negativas que presenta este estado carencial.

Abstract: En | Text: En | PDF: En

Trace element concentrations in water from São Francisco River using Particle Induced X-ray Emission (PIXE) and Synchroton Total Reflection X-ray Fluorescence (STXRF) techniques are measured. The main objective of this work was to characterize and to monitor the trace elements in the water of São Francisco River, as well as to provide valuable information about the levels of metallic ions pollutants. Water samples were collected monthly at five locations along the course of the river from July 2003 to April 2004. As an internal standard, 11.6 ppm of Yttrium was added to 10 ml of the water sample. The PIXE and TXRF measurements were performed at the Ion Beams and Materials Laboratory (LAMFI) and the Brazilian National Synchrotron Light Laboratory (LNLS), using a proton beam and a polychromatic X-ray beam, respectively. Si(Li) detectors were used to collect the X-ray spectra. Due to the excellent detection limits of the PIXE and STXRF analysis, up to 15 elements were quantified. The highest total content of Cr, As, Cu and Zn detected in river water are above the limits recommended by the environmental legislation.

Abstract: En | Text: En | PDF: En

Concentrations of trace metallic element as well as macronutrients were measured in water and plants from pond water. The aquatic macrophyte Salvinia sp. was evaluated for its trace metals removal potential in river water under laboratory conditions. The experiment were performed using several healthy acclimatized plants Salvinia sp. The water and grown plants were collected from ponds. For the trace element removal´s test, 30-35 grams of fresh aquatic plants were grown in river water into a greenhouse for ten weeks. Control plants were also grown during the experiment. Every two weeks, both plants and water samples were collected. After the end of each experiment, the growth rate was calculated. Trace element concentrations in plants and pond water were obtained using TXRF techniques. Values for the elements (K, Ca, Ti, Fe, Cr, Mn, Cu, Zn and Sr) concentrations in plant dry weight have been obtained after deducting metal contents of control plants. For each trace element, the aquatic Salvinia sp. plant showed to possess different affinity for the incorporation of the metals in its biomass. Results suggest the use of aquatic macrophytes Salvinia sp. for metal abatement in dilute wastewaters.

Abstract: En Es | Text: En Es | PDF: En | PDF: Es

The use of simple linear regression to data of pollen rain and vegetation cover in Patagonia (Province of Chubut, Argentina) allowed us to develop quantitative relationships between modern pollen rain perecentages and vegetation cover for the taxa Poaceae, Papilionoideae, Senecio type, and Mulinum spinosum. The analysis revealed a good fit of data to regression lines for all taxa, with high Pearson r coefficient values in the case of M. spinosum (0.82) and Senecio type (0.81), and somewhat lower values in the case of Poaceae (0.66) and Papilionoideae (0.61). These regressions allowed us to infer the presence or absence of regional pollen and predict the quantity of pollen in the absence of the vegetation producing it. In this regard, the studied pollen rain includes the regional contribution (except Papilionoideae), even though M. spinosum has a low contribution. This overrepresentation is attributed to long-distance transport associated to the westerly winds. These quantitative relationships will allow us to know past vegetational changes of these taxa from fossil pollen spectra in the studied area

La aplicación de un análisis de regresión lineal simple a datos de lluvia de polen y de vegetación, en una zona de la Patagonia (Provincia de Chubut, Argentina) permitió relacionar cuantitativamente los porcentajes de lluvia polínica y de cobertura de la vegetación para los taxa Poaceae, Papilionoideae, tipo Senecio y Mulinum spinosum. Se obtuvo un buen ajuste de las rectas de regresión para cada uno de los taxa considerados, con coeficientes de correlación r de Pearson altos para M. spinosum (0,82) y tipo Senecio (0,81) y coeficientes algo menores en el caso de Poaceae (0,66) y Papilionoideae (0,61). Estas regresiones permitieron inferir la presencia o ausencia de polen regional y el valor predictivo de la presencia de polen en ausencia de la vegetación que lo produce. Al respecto, la lluvia de polen estudiada incluye el aporte regional (excepto Papilionoideae) aun cuando M. spinosum tiene una baja contribución. Esta sobrerrepresentación es atribuible al transporte de larga distancia, a través de los vientos que provienen del oeste. Estas relaciones cuantitativas nos permitirán extrapolar cambios vegetacionales pasados en estos taxa a partir de espectros de polen fósil para el área de estudio
