    FCT_UIDB/05608/2020. FCT_UIDP/05608/2020.In poultry farms, the mixture of bedding material, chicken excrement, and feathers seems to play an important role in pathogen development which may contribute to a potential risk of zoonosis, spreading the disease through the food chain. The purpose of this study was to analyze microbial contamination in bedding material and other matrices as well as potential antimicrobial resistances in chicken production facilities and also to identify the sampling techniques and assays used. This study evidences the available data published, following the PRISMA methodology. Among the environmental samples, surface swabs were frequently used as a passive sampling technique. Morphological identification was performed in all studies. Of all the matrices, the bedding material was the most contaminated. Most studies focused on bacterial contamination, with Salmonella sp. and Campylobacter sp. being commonly reported and three studies evidenced fungal contamination, being Penicillium sp.- and Aspergillus sp.-dominant. Mycotoxin assessment was only performed in one study, being identified in all bedding samples. The screening for bacteria resistance evidenced bacteria multidrug resistance; however, fungal susceptibility to azoles was not assessed in any of the analyzed studies. Briefly, this review evidences microbial contamination in poultry facilities, emphasizing animals’ bedding as a potential source of contamination. Additionally, this study contributes to a sampling and analysis protocol proposal to assess microbial contamination in this setting. Additionally, the knowledge gaps identified highlight the need for further research regarding microbial contamination and toxicological potential on animals’ bedding in order to mitigate exposure in poultry pavilions.info:eu-repo/semantics/publishedVersio

Publisher Copyright: © 2023 by the authors.This study reports the search of available data published regarding microbial occupational exposure assessment in poultries, following the PRISMA methodology. Air collection through filtration was the most frequently used. The most commonly used passive sampling method was material collection such as dust, cages, soils, sediment, and wastewater. Regarding assays applied, the majority of studies comprised culture-based methods, but molecular tools were also frequently used. Screening for antimicrobial susceptibility was performed only for bacteria; cytotoxicity, virological and serological assays were also performed. Most of the selected studies focused on bacteria, although fungi, endotoxins, and β-glucans were also assessed. The only study concerning fungi and mycotoxins reported the carcinogenic mycotoxin AFB1. This study gives a comprehensive overview of microbial contamination in the poultry industry, emphasizing this setting as a potential reservoir of microbial pathogens threatening human, animal, and environmental health. Additionally, this research helps to provide a sampling and analysis protocol proposal to evaluate the microbiological contamination in these facilities. Few articles were found reporting fungal contamination in poultry farms worldwide. In addition, information concerning fungal resistance profile and mycotoxin contamination remain scarce. Overall, a One Health approach should be incorporated in exposure assessments and the knowledge gaps identified in this paper should be addressed in further research.publishersversionpublishe

    Ante los impactos negativos que las inundaciones han significado para la subcuenca del Rió Atoyac-Oaxaca de Juárez, es importante identificar qué zonas son vulnerables ante inundaciones, qué factores naturales se asocian con este fenómeno y qué áreas se encuentran en mayor riesgo. Estos son los objetivos de este trabajo. Para lograrlo, se siguió el enfoque geográfico de riesgo apoyado en el análisis espacial asistido por tecnología SIG. Con el fin de evaluar la vulnerabilidad biofísica, se construyó un índice (IVBF) utilizando el método multicriterio AHP. Los resultados indican que las áreas más vulnerables son el centro y los Valles de Tlacolula, Etla y Zaachila, explicado por los factores intrínsecos al territorio: su fisiografía, cercanía a cuerpos de agua, coberturas del suelo, tipos de suelo y geología. Asimismo las zonas en mayor riesgo se localizan en la zona conurbada de Oaxaca de Juárez, las cuales equivalente al 40% de la superficie total de la subcuenca. Dentro de esta región, los municipios de carácter urbano que son prioritarios de atender para evitar una condición de desastre son: San Jacinto Amilpas, Santa Lucía del Camino y Santa Cruz Xoxocotlán. En el contexto rural, la atención prioritaria deberá enfocarse en los municipios de Santa Cruz Papalutla, San Raymundo Jalpan y San Pedro Apóstol. Este trabajo abona al interés continuo del desarrollo métrico de la vulnerabilidad, el cual puede extenderse a otras dimensiones y a la evaluación integral del riesgo

Licensee MDPI, Basel, Switzerland.The composition of airborne microflora in sawmills may vary to a great degree depending on the kind of timber being processed and the technology of production being used. Cases of allergy alveolitis and asthma have been reported in woodworkers who were exposed to wood dust largely infected with microorganisms. The aim of this review article is to identify studies where the microbial occupational exposure assessment was performed in sawmills and the characteristics of the contamination found, as well as to identify which sampling methods and assays were applied. This study reports the search of available data published regarding microbial occupational exposure assessment in environmental samples from sawmills, following the Preferred Reporting Items for Systematic Reviews (PRISMA) methodology. The most used sampling method was air sampling, impaction being the most common method. Regarding analytical procedures for microbial characterization, morphological identification of fungi and bacteria was the most frequent approach. Screening for fungal susceptibility to azoles was performed in two studies and four studies applied molecular tools. Regarding microbial contamination, high fungal levels were frequent, as well as high bacteria levels. Fungal identification evidenced Penicillium as the most frequent genera followed by Aspergillus sp. Mycotoxins were not assessed in any of the analyzed studies. Microbial occupational exposure assessment in sawmills is crucial to allow this risk characterization and management.publishersversionpublishe

FCT_UIDP/05608/2020.Best poster awardIntroduction: The microbial exposure, as well as their metabolic products, has been frequently reported as a high risk of respiratory effects and general health hazards. Regarding the Portuguese legislation for IAQ, the microbial assessment covers only air sampling and culture-based methods (malt extract agar as only culture media to be applied). Fungal legal criteria consist of a fungal load ratio between indoor and outdoor, which should be lower than 1 (I/O<1). Purpose: Analyze the importance of including the characterization of the azole resistance profile in indoor air quality assessments.info:eu-repo/semantics/publishedVersio

    This manuscript presents the levels of six indicator polychlorinated biphenyl (PCB) congeners (IUPAC nos. 28, 52, 101, 138, 153 and 180) in the serum of 1880 individuals from a representative sample of the Spanish working population recruited between March 2009 and July 2010. Three out of the six PCBs studied (180, 153 and 138) were quantified in more than 99% of participants. PCB 180 was the highest contributor, followed by PCBs 153 and 138, with relative abundances of 42.6%, 33.2% and 24.2%, respectively. In contrast, PCBs 28 and 52 were detected in only 1% of samples, whereas PCB 101 was detectable in 6% of samples. The geometric mean (GM) for ΣPCBs138/153/180 was 135.4 ng/g lipid (95% CI: 121.3-151.2 ng/g lipid) and the 95th percentile was 482.2 ng/g lipid. Men had higher PCB blood concentrations than women (GMs 138.9 and 129.9 ng/g lipid respectively). As expected, serum PCB levels increased with age and frequency of fish consumption, particularly in those participants younger than 30 years of age. The highest levels we found were for participants from the Basque Country, whereas the lowest concentrations were found for those from the Canary Islands. The Spanish population studied herein had similar levels to those found previously in Greece and southern Italy, lower levels than those in France and central Europe, and higher PCB levels than those in the USA, Canada and New Zealand. This paper provides the first baseline information regarding PCB exposure in the Spanish adult population on a national scale. The results will allow us to establish reference levels, follow temporal trends and identify high-exposure groups, as well as monitor implementation of the Stockholm Convention in Spain.This work was funded as part of a research agreement between the Spanish Ministry of Agriculture, Food and the Environment n° EG042007 and the Institute of Health Carlos III (project nos.

    Translational research: A concept emerged from health sciences and exportable to education sciences

    Get PDF
    The objective of this paper was to analyze the concept and evolution of translational research in order to explore if it can be used in fields other than health sciences such as higher education. A mini review was conducted using Medline as a main source for identifying papers. We selected papers that appeared to be relevant according to our objective. Data extraction of these papers was made by summarizing documents using short textual descriptions. Search results yielded 1186 papers, 28 of which were finally selected for the mini review. The main aim of translational research is bridging the know do gap. Several multiphase models have been identified. The first described model had two phases (T1, T2) but there are models with three (T1-T3) or four phases (T1-T4). However, regardless of the model used, three main gaps exist that can be placed in the knowledge chain underpinning translational research. Translational research could be seen as a bidirectional bridge connecting the laboratory to practice either in health or in education. Its interdisciplinary back and forth ultimately contributes to improved health or education outcomes. This improvement can be achieved if the three gaps of the knowledge chain are overcome. Namely, these gaps are located: (1) between the discovery of new knowledge and dissemination to potential users of that knowledge; (2) between knowledge dissemination to potential users and its routine application to health or education practice; and (3) between clinical or educational practice and improvement of health or education outcomes.L'objectiu d'aquest treball va ser analitzar el concepte i l'evolució de la investigació translacional per tal d'explorar si es pot utilitzar en altres àmbits a part de les ciències de la salut com ara l'educació superior.El objetivo de este trabajo fue analizar el concepto y la evolución de la investigación translacional para explorar si se puede utilizar en otros ámbitos aparte de las ciencias de la salud como la educación superior

    Evaluación de la conducta activa: el Registro Semanal de Actividad Física (RSAF)

    The aim of this study was to propose the Weekly Physical Activity Log (RSAF in Spanish) to assess physical activity behaviour in adults. To this end, 132 adults (mean = 28.53 years; SD = 11.20) completed the RSAF. The energy expenditure (METs) of daily physical activities was obtained for a week and the percentile scores were calculated in terms of gender and age. The energy expenditure data were compared with the physical activity level and measures of fitness. The results show that active participants tend to have higher energy expenditure level than non-active participants, and the correlation between aerobic fitness and average weekly energy consumption is significant. These results show that the RSAF is useful and suitable for assessing daily physical activity and fitness in adults
