Mechanisms involved in Escherichia coli and Serratia marcescens removal during activated sludge wastewater treatment

Wastewater treatment reduces environmental contamination by removing gross solids and mitigating the effects of pollution. Treatment also reduces the number of indicator organisms and pathogens. In this work, the fates of two coliform bacteria, Escherichia coli and Serratia marcescens, were analyzed in an activated sludge process to determine the main mechanisms involved in the reduction of pathogenic microorganisms during wastewater treatment. These bacteria, modified to express green fluorescent protein, were inoculated in an activated sludge unit and in batch systems containing wastewater. The results suggested that, among the different biological factors implied in bacterial removal, bacterivorous protozoa play a key role. Moreover, a representative number of bacteria persisted in the system as free-living or embedded cells, but their distribution into liquid or solid fractions varied depending on the bacterium tested, questioning the real value of bacterial indicators for the control of wastewater treatment process. Additionally, viable but nonculturable cells constituted an important part of the bacterial population adhered to solid fractions, what can be derived from the competition relationships with native bacteria, present in high densities in this environment. These facts, taken together, emphasize the need for reliable quantitative and qualitative analysis tools for the evaluation of pathogenic microbial composition in sludge, which could represent an undefined risk to public health and ecosystem functions when considering its recycling.

Intervenciones grupales en mujeres con cáncer de mama para mejorar su calidad de vida

[Es]El propósito de este trabajo es realizar una revisión sistemática de las intervenciones de grupo llevadas a cabo con mujeres con cáncer de mama y comprobar en qué medida mejoran la calidad de vida de estas pacientes. Actualmente, debido a la creciente incidencia de este tipo de neoplasia, es preciso evaluar las intervenciones de las que se disponen para lograr un tratamiento efectivo, eficaz y eficiente. Para ello, la revisión se realizó empleando las bases de datos más relevantes, como PubMed, Scielo, Fundación Index y Cochrane Library, de manera que se seleccionaron 14 de los 24 artículos encontrados, rechazando 10 por no cumplir los objetivos del presente trabajo. Los resultados hallados mostraron que las intervenciones que se utilizaron para mejorar los factores psicológicos y sociales, fueron las más utilizadas, logrando mejorar el estado psicosocial de las pacientes. El resto de intervenciones grupales encontradas en esta revisión se empleó para reducir el dolor de las participantes, logrando disminuirlo y controlarlo. Para realizar estas valoraciones, los autores de los estudios analizados emplearon cuestionarios y escalas como el EORTC QLQ-C30, el EORTC QLQ-BR23, el HADS, el POMS, el STAI y la escala EVA. Finalmente se puede concluir que a pesar de la ayuda que estas intervenciones grupales suponen en la mejora de la calidad de vida para la paciente con cáncer de mama, estas no aumentan su supervivencia.

Implementation of the nursing process in a health area: models and assessment structures used

Objective: to analyze what nursing models and nursing assessment structures have been used in the implementation of the nursing process at the public and private centers in the health area Gipuzkoa (Basque Country). Method: a retrospective study was undertaken, based on the analysis of the nursing records used at the 158 centers studied. Results: the Henderson model, Carpenito's bifocal structure, Gordon's assessment structure and the Resident Assessment Instrument Nursing Home 2.0 have been used as nursing models and assessment structures to implement the nursing process. At some centers, the selected model or assessment structure has varied over time. Conclusion: Henderson's model has been the most used to implement the nursing process. Furthermore, the trend is observed to complement or replace Henderson's model by nursing assessment structures.

Community Turnover of Wood-Inhabiting Fungi across Hierarchical Spatial Scales

For efficient use of conservation resources it is important to determine how species diversity changes across spatial scales. In many poorly known species groups little is known about at which spatial scales the conservation efforts should be focused. Here we examined how the community turnover of wood-inhabiting fungi is realised at three hierarchical levels, and how much of community variation is explained by variation in resource composition and spatial proximity. The hierarchical study design consisted of management type (fixed factor), forest site (random factor, nested within management type) and study plots (randomly placed plots within each study site). To examine how species richness varied across the three hierarchical scales, randomized species accumulation curves and additive partitioning of species richness were applied. To analyse variation in wood-inhabiting species and dead wood composition at each scale, linear and Permanova modelling approaches were used. Wood-inhabiting fungal communities were dominated by rare and infrequent species. The similarity of fungal communities was higher within sites and within management categories than among sites or between the two management categories, and it decreased with increasing distance among the sampling plots and with decreasing similarity of dead wood resources. However, only a small part of community variation could be explained by these factors. The species present in managed forests were in a large extent a subset of those species present in natural forests. Our results suggest that in particular the protection of rare species requires a large total area. As managed forests have only little additional value complementing the diversity of natural forests, the conservation of natural forests is the key to ecologically effective conservation. As the dissimilarity of fungal communities increases with distance, the conserved natural forest sites should be broadly distributed in space, yet the individual conserved areas should be large enough to ensure local persistence.

El futuro del estado del bienestar

En este Trabajo fin de Grado se hace una reflexión interesante en torno al modelo social europeo, sus características en los distintos países, y, en comparación con el modelo americano. Se subrayan los pilares del Estado del Bienestar y su debilidad actual provocada por la crisis económica, proponiéndose posibles alternativas para su viabilidad. La Unión Europea se encuentra actualmente, en un momento crucial de su historia, donde las dudas sobre la viabilidad de su modelo social aumentan cada día, frente a las cuales tendrá que actuar adecuadamente para seguir garantizando el bienestar de su sociedad así como su crecimiento económico. Se explica las características del modelo social europeo; sus diferencias entre los países miembros, y, con otros modelos como el americano. Analizamos también el impacto de la crisis en el mercado de trabajo en los distintos escenarios y sus consecuencias sobre la pobreza, la cohesión social y la desigualdad, valorando el efecto negativo tanto en el crecimiento económico como en la democracia. En base a esos datos, que son distintos para cada país dependiendo de su historia y modelo social, se perfilan posibles medidas para superar la crisis económica y la supervivencia de bienestar europeo.

Do Nutritional Supplements Have a Role in Age Macular Degeneration Prevention?

Purpose. To review the proposed pathogenic mechanisms of age macular degeneration (AMD), as well as the role of antioxidants (AOX) and omega-3 fatty acids (omega-3) supplements in AMD prevention. Materials and Methods. Current knowledge on the cellular/molecular mechanisms of AMD and the epidemiologic/experimental studies on the effects of AOX and omega-3 were addressed all together with the scientific evidence and the personal opinion of professionals involved in the Retina Group of the OFTARED (Spain). Results. High dietary intakes of omega-3 and macular pigments lutein/zeaxanthin are associated with lower risk of prevalence and incidence in AMD. The Age-Related Eye Disease study (AREDS) showed a beneficial effect of high doses of vitamins C, E, beta-carotene, and zinc/copper in reducing the rate of progression to advanced AMD in patients with intermediate AMD or with one-sided late AMD. The AREDS-2 study has shown that lutein and zeaxanthin may substitute beta-carotene because of its potential relationship with increased lung cancer incidence. Conclusion. Research has proved that elder people with poor diets, especially with low AOX and omega-3 micronutrients intake and subsequently having low plasmatic levels, are more prone to developing AMD. Micronutrient supplementation enhances antioxidant defense and healthy eyes and might prevent/retard/modify AMD.
