Conocimientos sobre la tuberculosis en usuarios del transporte masivo en Santiago de Cali, Colombia

Knowledge about Tuberculosis (TB) is limited among the general population of Cali, the second city in Colombia with the highest burden of TB. Here, we sought to determine the level of knowledge about TB among users of the public transportation system of the city. We conducted a cross-sectional study using a structured questionnaire to collect information in 12 main stations of the transport system. Data were collected in a working day of March 2017. Out of 193 interviewed users, 80% answered to have limited knowledge about TB. However, most of the participants identified coughing as a symptom of TB (74.6%) and recognized that TB is a contagious disease (75.1%) that could be transmitted by the air (61.7%). Seventy percent of participants knew that TB is a curable disease. On the other hand, there were misconceptions regarding TB transmission and the identification of other classical symptoms of TB was limited. Understanding the level of knowledge about TB among the general population is key to design communicative and educational strategies to control and prevent this disease.Poco se conoce sobre los conocimientos sobre tuberculosis (TB) en Cali, segunda ciudad colombiana con mayor carga de la enfermedad. Esta investigación buscó determinar el grado de conocimientos sobre TB en usuarios del transporte masivo. Se realizó un estudio descriptivo de corte transversal aplicando un cuestionario a usuarios de 12 estaciones principales del sistema de transporte público en un día laboral de marzo de 2017. De 193 encuestados, el 80% manifestó conocer poco o nada sobre TB. La mayoría identificó la tos como síntoma (74,6%) y refirió que es una enfermedad contagiosa (75,1%), transmitida por aire (61,7%) y curable (70,5%). No es tan frecuente la identificación de otros síntomas y hay concepciones erróneas sobre la transmisión. Identificar los conocimientos de la población acerca de la enfermedad permite orientar estrategias comunicativas y educativas para prevenir y controlar la TB, dirigidas al público que converge en el sistema de transporte masivo.&nbsp

Predictive modeling of indoor dust lead concentrations: Sources, risks, and benefits of intervention

Lead (Pb) contamination continues to contribute to world-wide morbidity in all countries, particularly low- and middle-income countries. Despite its continued widespread adverse effects on global populations, particularly children, accurate prediction of elevated household dust Pb and the potential implications of simple, low-cost household interventions at national and global scales have been lacking. A global dataset (∼40 countries, n = 1951) of community sourced household dust samples were used to predict whether indoor dust was elevated in Pb, expanding on recent work in the United States (U.S.). Binned housing age category alone was a significant (p < 0.01) predictor of elevated dust Pb, but only generated effective predictive accuracy for England and Australia (sensitivity of ∼80%), similar to previous results in the U.S. This likely reflects comparable Pb pollution legacies between these three countries, particularly with residential Pb paint. The heterogeneity associated with Pb pollution at a global scale complicates the predictive accuracy of our model, which is lower for countries outside England, the U.S., and Australia. This is likely due to differing environmental Pb regulations, sources, and the paucity of dust samples available outside of these three countries. In England, the U.S., and Australia, simple, low-cost household intervention strategies such as vacuuming and wet mopping could conservatively save 70 billion USD within a four-year period based on our model. Globally, up to 1.68 trillion USD could be saved with improved predictive modeling and primary intervention to reduce harmful exposure to Pb dust sources

Determination of antioxidant compounds in foodstuff

© 2017 Scrivener Publishing LLC. Phenolic compounds, vitamins and carotenoids are naturally found in different foodstuff. These antioxidant compounds play an important role in human health and are of interest for the food, pharmaceutical and cosmeceutical industries. Modern chromatographic and spectrometric techniques have made analysis easier than ever before, but their success depends on the extraction method used. In fact, the different antioxidants are identifified using chromatographic techniques coupled to diff erent specififi c detectors according to the characteristics of each molecule. Beyond their well-known health-promoting effects, antioxidant molecules can also be used to functionalize or preserve the freshness, nutritive value, flflavor and color of foodstuff s, which justify their incorporation into several matrices. In this chapter, the most common antioxidant compounds in foodstuff will be described, as well as the methodologies involved in their extraction, separation, identifification and quantifification. The bioactive properties and industrial applications of these compounds through innovative techniques will also be taken into account.info:eu-repo/semantics/publishedVersio

Geochemistry and characterization of intermediate temperature eclogites from the Acatlan Complex, southern Mexico

The Acatlan Complex of southern Mexico is one of two high-pressure metamorphic belts reported in Mexico. This complex contains an extensive sequence of metabasic, pelitic, granitic, mafic, ultramafic and carbonate rocks affected by an eclogite-facies metamorphic event of apparently Devonian age and subsequent overprinting of amphibolite and greenschist metamorphism. The purpose of this study was to characterize the metabasic eclogites from the Paleozoic Acatlan Complex, southern Mexico in terms of their thermobarometric conditions of formation as well as to identify the nature of the magmatic precursors. The approach was to place constraints on the petrogenetic history of the eclogites. Microtextures indicate that equilibrium existed among mineral phases of garnet, sodic pyroxene and sodic-calcic amphibole in the eclogites. This indicates that a complete equilibration to a sensu-stricto named eclogite did not occur and eclogitic assemblages were only locally developed. According to electron microprobe analyses conducted in high-pressure mineral assemblages from two-type areas, the petrogenetic evolution of these rocks is bracketed between a maximum P-T conditions of 565 ± 37°C and 11-15 kbar for basic metaeclogites from the areas of Izucar de Matamoros and Piaxtla-Tecomatlan. Minimum P-T conditions of 343°C, 3.5 kbar were constrained for greenschist metamorphism. The obtained P-T path for the polymetamorphic rocks from the Acatlan Complex has similarities with those of metamorphic rocks from New Caledonia which has a less complicated retrogressional history than alpine eclogites. Analyses of major, trace and REE abundances were determined for representative samples. The whole-rock REE-patterns suggest that there was no significant REE mobility of the protolith system. Consistent geochemistry allows identification of the protoliths as Mid Ocean Ridge Basalts (MORB), Oceanic Island Basalts (OIB) and Island Arc Volcanism (IAV). Geochemical evidence also indicates that the Acatlan Complex eclogites are tectonically emplaced slices of oceanic material suggesting a more complex tectonic regime. The data from this work suggest that the basic metaeclogites could be the product of two different convergent tectonic scenarios: (a) a collision of a small block(s) such as an island arc or a microcontinent or (b) lateral or non-frontal collision of a continent

Distribution of Arsenic and Risk Assessment of Activities on Soccer Pitches Irrigated with Arsenic-Contaminated Water

The aim of this research was to estimate the risk of human exposure to arsenic due to sporting activities in a private soccer club in Mexico, where arsenic-contaminated water was regularly used for irrigation. For this purpose, the total concentration in the topsoil was considered for risk assessment. This was accomplished through three main objectives: (1) measuring arsenic concentrations in irrigation water and irrigated soils, (2) determining arsenic spatial distribution in shallow soils with Geographical Information Systems (GIS) using geostatistical analysis, and (3) collecting field and survey data to develop a risk assessment calculation for soccer activities in the soccer club. The results showed that the average arsenic concentrations in shallow soils (138.1 mg/kg) were 6.2 times higher than the Mexican threshold for domestic soils (22 mg/kg). Furthermore, dermal contact between exposed users and contaminated soils accounted for a maximum carcinogenic risk value of 1.8 &times; 10&minus;5, which is one order of magnitude higher than the recommended risk value, while arsenic concentrations in the irrigation water were higher (6 mg/L) than the WHO&rsquo;s permissible threshold in drinking water, explaining the contamination of soils after irrigation. To the best of our knowledge, this is the first risk study regarding dermal contact with arsenic following regular grass irrigation with contaminated water in soccer pitches

Using a Sensitivity Analysis and Spatial Clustering to Determine Vulnerability to Potentially Toxic Elements in a Semiarid City in Northwest Mexico

The Getis-Ord Gi* statistic clustering technique was used to create a hot spot exposure map using 14 potentially toxic elements (PTEs) found in urban dust samples in a semiarid city in northwest Mexico. The dust distribution and deposition in this city are influenced by the seasonal wind and rain from the North American Monsoon. The spatial clustering patterns of hot spots were used in combination with a sensitivity analysis to determine which variables most influenced the PTE hot spot exposure base map. The hot spots areas (%) were used as indicators of environmental vulnerability, and a final integrated map was selected to represent the highest vulnerability of PTEs with a 99% level of confidence. The results of the sensitivity analysis indicated that the flood zones and pervious and impervious zones were the most sensitive variables due to their weight in the spatial distribution. The hot spot areas were reduced by 60.4% by not considering these variables. The hot spot analysis resulted in an effective tool that allowed the combination of different spatial layers with specific characteristics to determine areas that present greater vulnerability to the distribution of PTEs, with impacts on public and environmental health
