Associating sporadic, foodborne illness caused by Shiga toxin-producing Escherichia coli with specific foods : a systematic review and meta-analysis of case-control studies

Shiga toxin-producing Escherichia coli (STEC) infections are a significant public health issue, with foodborne transmission causing >1 million illnesses worldwide each year. We conducted a systematic review and meta-analysis (PROSPERO registry # CRD42017074239), to determine the relative association of different food types with sporadic illnesses caused by STEC. Searches were conducted from 01 August to 30 September 2017, using bibliographic and grey literature databases, websites and expert consultation. We identified 22 case-control studies of sporadic STEC infection in humans, from 10 countries within four World Health Organization subregions, from 1985 to 2012. We extracted data from 21 studies, for 237 individual measures in 11 food categories and across three status types (raw or undercooked, not raw and unknown). Beef was the most significant food item associated with STEC illness in the Americas and Europe, but in the Western Pacific region, chicken was most significant. These findings were not significantly moderated by the raw or cooked status of the food item, nor the publication year of the study. Data from the African, South-East Asian and Eastern Mediterranean subregions were lacking and it is unclear whether our results are relevant to these regions

Rodent models of heart failure: an updated review

Heart failure (HF) is one of the major health and economic burdens worldwide, and its prevalence is continuously increasing. The study of HF requires reliable animal models to study the chronic changes and pharmacologic interventions in myocardial structure and function and to follow its progression toward HF. Indeed, during the past 40 years, basic and translational scientists have used small animal models to understand the pathophysiology of HF and find more efficient ways of preventing and managing patients suffering from congestive HF (CHF). Each species and each animal model has advantages and disadvantages, and the choice of one model over another should take them into account for a good experimental design. The aim of this review is to describe and highlight the advantages and drawbacks of some commonly used HF rodents models, including both non-genetically and genetically engineered models, with a specific subchapter concerning diastolic HF models

XMM-Newton observations of the low-luminosity cataclysmic variable V405 Pegasi

V405 Peg is a low-luminosity cataclysmic variable (CV) that was identified as the optical counterpart of the bright, high-latitude ROSAT all-sky survey source RBS1955. The system was suspected to belong to a largely undiscovered population of hibernating CVs. Despite intensive optical follow-up its subclass however remained undetermined. We want to further classify V405 Peg and understand its role in the CV zoo via its long-term behaviour, spectral properties, energy distribution and accretion luminosity. We perform a spectral and timing analysis of \textit{XMM-Newton} X-ray and ultra-violet data. Archival WISE, HST, and Swift observations are used to determine the spectral energy distribution and characterize the long-term variability. The X-ray spectrum is characterized by emission from a multi-temperature plasma. No evidence for a luminous soft X-ray component was found. Orbital phase-dependent X-ray photometric variability by $\sim50\%$ occurred without significant spectral changes. No further periodicity was significant in our X-ray data. The average X-ray luminosity during the XMM-Newton observations was L_X, bol simeq 5e30 erg/s but, based on the Swift observations, the corresponding luminosity varied between 5e29 erg/s and 2e31 erg/son timescales of years. The CV subclass of this object remains elusive. The spectral and timing properties show commonalities with both classes of magnetic and non-magnetic CVs. The accretion luminosity is far below than that expected for a standard accreting CV at the given orbital period. Objects like V405 Peg might represent the tip of an iceberg and thus may be important contributors to the Galactic Ridge X-ray Emission. If so they will be uncovered by future X-ray surveys, e.g. with eROSITA.Comment: A&A, in pres

Miniestaquia de Eucalyptus benthamii x E. dunnii em substratos a base de casca de arroz carbonizada.

Objetivou-se avaliar a viabilidade técnica da utilização de diferentes granulometrias de casca de arroz carbonizada, pura ou em mistura com fibra de coco, substrato comercial a base de casca de pinus e vermiculita como componentes de substratos para produção de mudas de Eucalyptus benthamii x E. dunnii via miniestaquia. Para tanto, foram montados 14 substratos, nos quais as miniestacas foram enraizadas para produção das mudas (60 dias em casa de vegetação, 30 dias em casa de sombra e 30 dias em área de pleno sol). Avaliou-se: 1) a sobrevivência das miniestacas, número de raízes e comprimento da maior raiz na saída da casa de vegetação; 2) a sobrevivência na saída da casa de sombra e; 3) o percentual final de enraizamento após a permanência na área de pleno sol. Com base nos resultados obtidos, conclui-se que a casca de arroz carbonizada pode ser utilizada pura (granulometria de 0,5 a 1 mm e em sua forma íntegra) ou em composição com vermiculita (50%) como substrato para produção de mudas do híbrido em questão via miniestaquia

Los efectos de las experiencias socioeducativas de adolescentes extranjeros en una sociedad de destino : ¿integración o des-integración?

Este texto se presentó como comunicación al II Congreso Internacional de Etnografía y Educación: Migraciones y Ciudadanías. Universidad Autónoma de Barcelona, Barcelona, 5-8 Septiembre 2008.La integración socioeducativa de los hijos e hijas de las personas inmigradas a España es una preocupación vigente. La presencia de diferentes comunidades inmigradas en Barcelona sigue provocando cambios en diversas áreas del panorama social, sobre todo en lo que se refiere a la educación. El crecimiento de estos colectivos ha incrementado los los debates relacionados con las medidas sociales, políticas y educacionales que puedan ayudar a "integrar" tanto a los recién llegados, como a los que ya llevan tiempo en la sociedad pero todavía no han descubierto su espacio social. Sin embargo, ¿Qué sería realmente estar "integrado" en una sociedad diferente a la sociedad de origen? ¿Hablar el idioma local? ¿Trabajar? ¿Estudiar? ¿Conocer personas del país? ¿Votar? ¿Dominar los códigos sociales? Apartir de las distintas vivencias por las cuales pueden pasar los nuevos alumnos en la sociedad de destino en su proceso de integración se podría preguntar por un lado ¿cómo las experiencias socioeducativas de adolescentes extranjeros pueden influenciar en este proceso? Por otro lado, en función de dichas experiencias ¿se les puede "encerrar" en una única clase de alumnos integrados o no integrados en el nuevo entorno socioeducativo? Este texto tiene como objetivo presentar los resultados de una investigación realizada para mi tesis doctoral sobre la integración socioeducativa de adolescentes brasileños en escuelas de Barcelona. El trabajo empírico de la investigación ha sido realizado durante el curso 2004-2005 en escuelas publicas y privadas de Barcelona y los 17 participantes eran adolescentes brasileños entre 12 y 16 años residentes en la ciudad entre 6 meses y 6 años. En un primer momento relataré algunas de las experiencias de los adolescentes brasileños al confrontarse con un nuevo sistema educativo y en un segundo momento trataré de abordar los efectos de estas experiencias en el proceso de integración de este grupo concreto en la nueva sociedad barcelonesa
