La escuela es el espacio social por excelencia para educar en el principio de acogida como elemento básico para la convivencia intercultural, así como en la conciencia crítica para saber detectar y modificar los factores generadores de incomprensión e injusticia. Este artículo narra cómo educar ciudadanos con diferentes identidades culturales, acercándonos a la comprensión cultural y ética del otro, a partir de unos valores comunes para que se favorezca así la cohesión social. Esta solidaridad moral acerca de la pluralidad cultural significa un cambio de percepción basado en la confianza depositada en las posibilidades de cada ser humano. Por eso se reclama al profesorado de educación secundaria, a través de la elaboración de una guía didáctica en valores, una actitud abierta, plural y acogedora, que genere elementos de cohesión social y superación de prejuicios.

Background: While several studies have analysed sex and socioeconomic differences in cancer incidence and mortality, sex differences in oncological health care have been seldom considered. Objective: To investigate sex based inequalities in hospital readmission among patients diagnosed with colorectal cancer. Design: Prospective cohort study. Setting: Hospital Universitary in L¿Hospitalet (Barcelona, Spain). Participants: Four hundred and three patients diagnosed with colorectal between January 1996 and December 1998 were actively followed up until 2002. Main outcome measurements and methods: Hospital readmission times related to colorectal cancer after surgical procedure. Cox proportional model with random effect (frailty) was used to estimate hazard rate ratios and 95% confidence intervals of readmission time for covariates analysed. Results: Crude hazard rate ratio of hospital readmission in men was 1.61 (95% CI 1.21 to 2.15). When other significant determinants of readmission were controlled for (including Dukes¿s stage, mortality, and Charlson¿s index) a significant risk of readmission was still present for men (hazard rate ratio: 1.52, 95% CI 1.17 to 1.96). Conclusions: In the case of colorectal cancer, women are less likely than men to be readmitted to the hospital, even after controlling for tumour characteristics, mortality, and comorbidity. New studies should investigate the role of other non-clinical variable such as differences in help seeking behaviours or structural or personal sex bias in the attention given to patients.

Background: Chronic Obstructive Pulmonary Disease (COPD) is characterized by an enhanced inflammatory response to smoking that persists despite quitting. The resolution of inflammation (catabasis) is a complex and highly regulated process where tissue resident macrophages play a key role since they phagocytose apoptotic cells (efferocytosis), preventing their secondary necrosis and the spill-over of their pro-inflammatory cytoplasmic content, and release pro-resolution and tissue repair molecules, such as TGFβ, VEGF and HGF. Because inflammation does not resolve in COPD, we hypothesized that catabasis may be abnormal in these patients. Methods: To explore this hypothesis, we studied lung tissue samples obtained at surgery from 21 COPD patients,22 smokers with normal spirometry and 13 non-smokers controls. In these samples we used: (1)immunohistochemistry to assess the expression of CD44, CD36, VEGF and TGFβ in lung macrophages; (2) real time PCR to determine HGF, PPARγ, TGFβ, VEGF and MMP-9 gene expression; and, (3) ELISA to quantify lipoxin A4, a lipid mediator of catabasis. Results: We found that current and former smokers with COPD showed: (1) more inflammation (higher MMP-9 expression); (2) reduced macrophage surface expression of CD44, a key efferocytosis receptor; and, (3) similar levels of TGFβ, VEGF, HGF, PPARγ, and lipoxin A4 than smokers with normal spirometry, despite the presence of inflammation and disease. Conclusions: These results identify several potential abnormalities of catabasis in patients with COPD.

Background: In recent years, microRNA (miRNA) pathways have emerged as a crucial system for the regulation of tumorogenesis. miR-SNPs are a novel class of single nucleotide polymorphisms that can affect miRNA pathways. Design and Methods: We analyzed eight miR-SNPs by allelic discrimination in 141 patients with Hodgkin lymphoma and correlated the results with treatment-related toxicity, response, disease-free survival (DFS) and overall survival (OS). Results: The KRT81 (rs3660) GG genotype was associated with an increased risk of neurological toxicity (P=0.016), while patients with XPO5 (rs11077) AA or CC genotypes had a higher rate of bleomycin-associated pulmonary toxicity (P=0.048). Both miR-SNPs emerged as independent factors in the multivariate analysis. The XPO5 AA and CC genotypes were also associated with a lower response rate (P=0.036). XPO5 (P=0.039) and TRBP (rs784567) (P=0.022) genotypes emerged as prognostic markers for DFS, and XPO5 was also associated with OS (P=0.033). In the multivariate analysis, only XPO5 emerged as an independent prognostic factor for DFS (HR: 2.622; 95%CI 1.039-6.620; P=0.041). Given the influence of XPO5 and TRBP as individual markers, we then investigated the combined effect of these miR-SNPs. Patients with both the XPO5 AA/CC and TRBP TT/TC genotypes had the shortest DFS (P=0.008) and OS (P=0.008). Conclusion: miR-SNPs can add useful prognostic information on treatment-related toxicity and clinical outcome in Hodgkin lymphoma and can be used to identify patients likely to be chemoresistant or to relapse.

L’objectiu prioritari d’aquesta intervenció, presentada en el marc dels MQD (Mòduls de qualitat docent) del curs 2010-2011, titulada Projecte Gutenberg, ha estat la pràctica de realitzar uns treballs cooperatius amb un grup classe per tal d’assolir la competència bàsica de saber treballar en equip i de ser conscient de la responsabilitat que aquest treball requereix per part de cada alumne. La finalitat, però, d’aquest projecte ha estat també la publicació d’un opuscle (llibret amb ISBN) amb un total de deu articles a partir de cinc temàtiques diferents triades pels mateixos alumnes. Cada un d’aquests temes s’ha tractat des de dues perspectives diferents: una més global, des d’una visió social, i l’altra més concreta, des d’una visió educativa. Aquest projecte proposava tanmateix una activitat transversal programada duta a terme en el marc de la Trobada Internacional per la Pau celebrada a Barcelona i organitzada per la Comunitat de Sant Egidi, dels dies 3 al 5 d’octubre del 2010. El grup classe que ha participat d’aquest esdeveniment ha estat el de segon curs de Magisteri del Grau de Primària (EP, tarda). El projecte s’ha realitzat des del mòdul d’Humanitats Cristianisme i Cultura i des dels seminaris corresponents al mòdul 2, amb la col·laboració dels seus tutors/es durant el primer semestre del curs 2010-2011.

O objetivo deste trabalho foi avaliar os efeitos da suplementação da dieta de tambacus com concentrações de vitamina E sobre variáveis de desempenho e hematológicas, bem como determinar a relação da atividade da glutationa peroxidase com a inclusão de vitamina E e selênio na dieta. Foram utilizados 250 juvenis de tambacu, divididos em 25 aquários. A dieta basal constituiu-se de ração peletizada com 32% de proteína bruta e 3.300 kcal kg-1 de energia digestível, e inclusão de 0,40 mg kg-1 de Se. As dietas-teste - isoprotéicas e isoenergéticas - foram compostas da dieta basal com diferentes concentrações de vitamina E (0, 100, 200, 300, 400 mg kg-1), em delineamento inteiramente ao acaso, com cinco tratamentos e cinco repetições. Não foi observado efeito significativo da suplementação com vitamina E sobre o comprimento total, volume corpuscular médio, concentração de hemoglobina corpuscular média e número de eritrócitos, nem sobre a atividade da glutationa peroxidase. Peso final e conversão alimentar aparente, no entanto, sofreram efeito dos tratamentos suplementados. O teor de 400 mg kg-1 de vitamina E melhorou o comprimento padrão e ganho de peso. A suplementação da dieta com vitamina E resulta em melhor desempenho produtivo de tambacus.

The addition of some fat co- and by-products to feeds is usual nowadays; however, the regulations of their use are not always clear and vary between countries. For instance, the use of recycled cooking oils is not allowed in the European Union, but they are used in other countries. However, oils recovered from industrial frying processes could show satisfactory quality for this purpose. Here we studied the effects of including oils recovered from the frying industry in rabbit and chicken feeds (at 30 and 60 g/kg, respectively) on the fatty acid (FA) and tocol (tocopherol + tocotrienol) compositon of meat, liver and plasma, and on their oxidative stability. Three dietary treatments (replicated eight times) were compared: fresh non-used oil (LOX); oil discarded from the frying industry, having a high content of secondary oxidation compounds (HOX); and an intermediate level (MOX) obtained by mixing 50 : 50 of LOX and HOX. The FA composition of oil diets and tissues was assessed by GC, their tocol content by HPLC, the thiobarbituric acid value was used to assess tissue oxidation status, and the ferrous oxidation-xylenol orange method was used to assess the susceptibility of tissues to oxidation. Our results indicate that FA composition of rabbit and chicken meat, liver and plasma was scarcely altered by the addition of recovered frying oils to feed. Differences were encountered in the FA composition between species, which might be attributed mainly to differences in the FA digestion, absorption and metabolism between species, and to some physiological dietary factors (i.e. coprophagy in rabbits that involves fermentation with FA structure modification). The α-tocopherol (αT) content of tissues was reduced in response to the lower αT content in the recovered frying oil. Differences in the content of other tocols were encountered between chickens and rabbits, which might be attributable to the different tocol composition of their feeds, as well as to species differences in the digestion and metabolism of tocols. Tissue oxidation and susceptibility to oxidation were in general low and were not greatly affected by the degree of oxidation of the oil added to the feeds. The relative content of polyunsaturated fatty acids/αT in these types of samples would explain the differences observed between species in the susceptibility of each tissue to oxidation. According to our results, oils recovered from the frying industry could be useful for feed uses.

Considering teams as complex adaptive systems (CAS) this study deals with changes in team effectiveness over time in a specific context: professional basketball. The sample comprised 23 basketball teams whose outcomes were analysed over a 12-year period according to two objective measures. The results reveal that all the teams showed chaotic dynamics, one of the key characteristics of CAS. A relationship was also found between teams showing low-dimensional chaotic dynamics and better outcomes, supporting the idea of healthy variability in organizational behaviour. The stability of the squad was likewise found to influence team outcomes, although it was not associated with the chaotic dynamics in team effectiveness. It is concluded that studying teams as CAS enables fluctuations in team effectiveness to be explained, and that the techniques derived from nonlinear dynamical systems, developed specifically for the study of CAS, are useful for this purpose.

La construcción del Espacio Europeo de Educación Superior (EEES) tiene como objetivo disponer de un espacio abierto en el que no existan obstáculos a la movilidad de estudiantes, titulados, profesores y personal de administración. El sistema se articula en torno al reconocimiento de titulaciones y otras calificaciones de educación superior, la transparencia (un sistema de titulaciones comprensibles y comparables organizado en tres ciclos) y la cooperación europea en la garantía de la calidad Ante este gran reto, la enseñanza universitaria ha tenido que reorganizarse y los planes de estudio de cada facultad han tenido que adaptarse a las nuevas exigencias del EEES. Además las metodologías docentes centran su interés en un seguimiento más tutorizado del alumno, para garantizar su aprendizaje, no sólo en la adquisición de conocimientos sino también de competencias.
