Perfil de la microbiota en equipamiento de empresas tradicionales de embutidos crudo-curados

Las autoras de este artículo han elaborado un trabajo para caracterizar la microbiota tecnológica, deteriorante y patógena en el equipamiento principal de las fábricas de embutidos tradicionales representativas del sector cárnico en Cataluña.

Micropolítica de los espacios públicos interiores

Este ensayo intenta resaltar los posibles puentes de oración y diálogo que existen entre la teoría política contemporánea y algunos teóricos de la tradición psicoanalítica del siglo veinte, como es el caso de su propio inventor, Sigmund Freud, y también dos de sus más controvertidos discípulos: Melanie Klein y Heinz Kohut. En concreto, me propongo reflexionar en torno al problema de la interioridad política del individuo-ciudadano y de cómo, a partir del descubrimiento freudiano de las dimensiones no conscientes del pensamiento (Ello), categorías cuya genealogía se entiende como plenamente política –tales como omnipotencia/impotencia, infancia e identidad– son transferidas o metaforizadas a fin de alumbrar la comprensión del psiquismo individual. En armonía con una forma de pensar retórica, el artículo aborda ciertos tropoi del psicoanálisis, el complejo de Edipo y el relato de Ulises y su hijo Telémaco, como dos mitos que simbolizan las políticas del abandono y de la reparación en los espacios públicos interiores del ciudadano.

Methods and representativeness of European surveys in children and adolescents: the KIDSCREEN study

Background: The objective of the present study was to compare three different sampling and questionnaire administration methods used in the international KIDSCREEN study in terms of participation, response rates, and external validity. Methods: Children and adolescents aged 8–18 years were surveyed in 13 European countries using either telephone sampling and mail administration, random sampling of school listings followed by classroom or mail administration, or multistage random sampling of communities and households with self-administration of the survey materials at home. Cooperation, completion, and response rates were compared across countries and survey methods. Data on non-respondents was collected in 8 countries. The population fraction (PF, respondents in each sex-age, or educational level category, divided by the population in the same category from Eurostat census data) and population fraction ratio (PFR, ratio of PF) and their corresponding 95% confidence intervals were used to analyze differences by country between the KIDSCREEN samples and a reference Eurostat population. Results: Response rates by country ranged from 18.9% to 91.2%. Response rates were highest in the school-based surveys (69.0%–91.2%). Sample proportions by age and gender were similar to the reference Eurostat population in most countries, although boys and adolescents were slightly underrepresented (PFR <1). Parents in lower educational categories were less likely to participate (PFR <1 in 5 countries). Parents in higher educational categories were overrepresented when the school and household sampling strategies were used (PFR = 1.78–2.97). Conclusion: School-based sampling achieved the highest overall response rates but also produced slightly more biased samples than the other methods. The results suggest that the samples were sufficiently representative to provide reference population values for the KIDSCREEN instrument.

Setting priorities in clinical and health services research: Properties of an adapted and updated method

Objectives: The objectives of this study is to review the set of criteria of the Institute of Medicine (IOM) for priority-setting in research with addition of new criteria if necessary, and to develop and evaluate the reliability and validity of the final priority score. Methods: Based on the evaluation of 199 research topics, forty-five experts identified additional criteria for priority-setting, rated their relevance, and ranked and weighted them in a three-round modified Delphi technique. A final priority score was developed and evaluated. Internal consistency, test–retest and inter-rater reliability were assessed. Correlation with experts’ overall qualitative topic ratings were assessed as an approximation to validity. Results: All seven original IOM criteria were considered relevant and two new criteria were added (“potential for translation into practice”, and “need for knowledge”). Final ranks and relative weights differed from those of the original IOM criteria: “research impact on health outcomes” was considered the most important criterion (4.23), as opposed to “burden of disease” (3.92). Cronbach’s alpha (0.75) and test–retest stability (interclass correlation coefficient = 0.66) for the final set of criteria were acceptable. The area under the receiver operating characteristic curve for overall assessment of priority was 0.66. Conclusions: A reliable instrument for prioritizing topics in clinical and health services research has been developed. Further evaluation of its validity and impact on selecting research topics is required
