OBJECTIVES: To assess the extent to which stage at diagnosis and adherence to treatment guidelines may explain the persistent differences in colorectal cancer survival between the USA and Europe. DESIGN: A high-resolution study using detailed clinical data on Dukes' stage, diagnostic procedures, treatment and follow-up, collected directly from medical records by trained abstractors under a single protocol, with standardised quality control and central statistical analysis. SETTING AND PARTICIPANTS: 21 population-based registries in seven US states and nine European countries provided data for random samples comprising 12 523 adults (15-99 years) diagnosed with colorectal cancer during 1996-1998. OUTCOME MEASURES: Logistic regression models were used to compare adherence to 'standard care' in the USA and Europe. Net survival and excess risk of death were estimated with flexible parametric models. RESULTS: The proportion of Dukes' A and B tumours was similar in the USA and Europe, while that of Dukes' C was more frequent in the USA (38% vs 21%) and of Dukes' D more frequent in Europe (22% vs 10%). Resection with curative intent was more frequent in the USA (85% vs 75%). Elderly patients (75-99 years) were 70-90% less likely to receive radiotherapy and chemotherapy. Age-standardised 5-year net survival was similar in the USA (58%) and Northern and Western Europe (54-56%) and lowest in Eastern Europe (42%). The mean excess hazard up to 5 years after diagnosis was highest in Eastern Europe, especially among elderly patients and those with Dukes' D tumours. CONCLUSIONS: The wide differences in colorectal cancer survival between Europe and the USA in the late 1990s are probably attributable to earlier stage and more extensive use of surgery and adjuvant treatment in the USA. Elderly patients with colorectal cancer received surgery, chemotherapy or radiotherapy less often than younger patients, despite evidence that they could also have benefited.

INTRODUCTION The aim of the present study was to investigate the possible role of CD40 and CD40 ligand (CD40LG) genes in the susceptibility and phenotype expression of systemic sclerosis (SSc). METHODS In total, 2,670 SSc patients and 3,245 healthy individuals from four European populations (Spain, Germany, The Netherlands, and Italy) were included in the study. Five single-nucleotide polymorphisms (SNPs) of CD40 (rs1883832, rs4810485, rs1535045) and CD40LG (rs3092952, rs3092920) were genotyped by using a predesigned TaqMan allele-discrimination assay technology. Meta-analysis was assessed to determine whether an association exists between the genetic variants and SSc or its main clinical subtypes. RESULTS No evidence of association between CD40 and CD40LG genes variants and susceptibility to SSc was observed. Similarly, no significant statistical differences were observed when SSc patients were stratified by the clinical subtypes, the serologic features, and pulmonary fibrosis. CONCLUSIONS Our results do not suggest an important role of CD40 and CD40LG gene polymorphisms in the susceptibility to or clinical expression of SSc.

BACKGROUND Persistence of anti-tumor necrosis factor (TNF) therapy in rheumatoid arthritis (RA) is an overall marker of treatment success. OBJECTIVE To assess the survival of anti-TNF treatment and to define the potential predictors of drug discontinuation in RA, in order to verify the adequacy of current practices. DESIGN An observational, descriptive, longitudinal, retrospective study. SETTING The Hospital ClÃnico Universitario de Valladolid, Valladolid, Spain. PATIENTS RA patients treated with anti-TNF therapy between January 2011 and January 2012. MEASUREMENTS Demographic information and therapy assessments were gathered from medical and pharmaceutical records. Data is expressed as means (standard deviations) for quantitative variables and frequency distribution for qualitative variables. Kaplan-Meier survival analysis was used to assess persistence, and Cox multivariate regression models were used to assess potential predictors of treatment discontinuation. RESULTS In total, 126 treatment series with infliximab (n = 53), etanercept (n = 51) or adalimumab (n = 22) were administered to 91 patients. Infliximab has mostly been used as a first-line treatment, but it was the drug with the shortest time until a change of treatment. Significant predictors of drug survival were: age; the anti-TNF agent; and the previous response to an anti-TNF drug. LIMITATION The small sample size. CONCLUSION The overall efficacy of anti-TNF drugs diminishes with time, with infliximab having the shortest time until a change of treatment. The management of biologic therapy in patients with RA should be reconsidered in order to achieve disease control with a reduction in costs.

L’objectiu del present projecte és la proposta (disseny i estimació econòmica) d’un sistema de tractament de les aigües i els fangs generats a un escorxador porcà de Granollers. Per tal de portar a terme aquest estudi, es va realitzar una anà lisi de la situació prèvia a l’escorxador, del diagrama de flux de les instal·lacions existents, de les necessitats del sector, dels lÃmits d’abocament fixats pel Reglament del Consorci del Besòs, i finalment de la caracterització de les aigües residuals generades (en quantitat i qualitat) aixà com dels fangs produïts. Arran d’aquesta anà lisi es va realitzar un estudi experimental d’optimització del tractament fisicoquÃmic, i en base als resultats es van generar diferents alternatives de tractament, es va simular el seu comportament, i es va fer una avaluació comparativa dels costos i rendiments estimats

La metodologia del Treball per Projectes té cada cop més implantació en les nostres aules catalanes. No obstant, el cert es que aquest tipus de treball es realitza, majorità riament, als centres de primà ria. El treball que es presenta a continuació pretén cercar, a un institut públic les causes d’aquest desequilibri però també analitzar els punts forts i febles d’aquesta metodologia, a partir de les vivències i els coneixements de tots els agents implicats

Aquest projecte és l’exemplificació del punt on la teoria i la prà ctica s’uneixen. Mostra com la tasca socioeducativa que es duu a terme a un recurs on es dóna atenció residencial a joves (majors d’edat) amb una mesura judicial de règim obert, pot encaixar perfectament amb el que teoria de la resiliència argumenta. S’utilitza el model resilient de la casita el qual es fa servir de cinc possibles à rees d’intervenció. Es tracta d’un estudi on es justifiquen les raons de per què el Pis de Joves d’Emancipació pot ser definit com una Institució Resilient

We appreciate the interest shown by Vidal-Pérez et al. in our article published recently in Revista Española de CardiologÃa,1 which provides us with an opportunity to present some interesting additional information not included in the article itself. We agree on the importance of knowing the thromboembolic risk of the population included in the OFRECE study, both for patients with a diagnosis of atrial fibrillation and for the general population. In our study, the mean (standard deviation) CHADS2 and CHAD2DS2-VASc of patients with atrial fibrillation was 2.3 (1.3) and 3.8 (1.6), respectively. In the general population, the mean (standard deviation) CHADS2 and CHAD2DS2-VASc of patients with atrial fibrillation was 0.8 (1) and 1.8 (1.5), respectively. The distribution of both scales is in agreement with that of the Val-FAAP and AFABE studies,2, 3 although the similarity is greater in the 2 population-based studies (Figure). These data are, we believe, relevant because they show that the level of risk in the population with atrial fibrillation is very similar to that of the populations included in clinical trials with new oral anticoagulants. In addition, an increasing body of evidence suggests that thromboembolic risk, as measured with these scales in the population without a diagnosis of atrial fibrillation, is associated with the onset of events.

Not much has been said about the grammar of Iraqi Arabic. This research is an attempt to shed light on the nature of IA relative clauses. The research focuses on the behavior of the resumptive strategy as opposed to the gap strategy. We consider islandhood, Weak and Strong CrossOver, reconstruction and scope binding, in order to further understand the behavior of resumption. The final conclusion reached is that in Iraqi Arabic the resumptive strategy is actually related to the gap strategy in several respects; and in those where it differs we propose that gaps (traces) are replaced by trace+pronoun complex

Introducción Estudios en colecistectomÃas y cáncer colorrectal demostraron que la laparoscopia genera menor respuesta inflamatoria sistémica. Escasos trabajos en cáncer gástrico evalúan el impacto inflamatorio en laparoscopia y emplean metodologÃa deficiente. Hipótesis Demostrar mediante el estudio de tejido peritoneal la menor respuesta inflamatoria(protein-arrays) en pacientes gastrectomizados por laparoscopia vs. vÃa abierta. Material y métodos 26 pacientes: laparoscópica (12) vs. abierta (14); 2010-2012. Resultados Basados en TNF muestran incremento similar de respuesta a la agresión quirúrgica (aunque hubo diferencias en valores finales en ambos abordajes). Conclusiones Resultados preliminares apuntan hacia conclusiones estadÃsticamente significativas que apoyen nuestra hipótesis: menor respuesta inflamatoria en laparoscopia y correlación con datos clÃnicos.

L´ecocardiografia per a estimar volums i funció ventricular dreta en malalts amb Tetralogia de Fallot (TF) està limitada per la importà ncia del tracte de sortida de ventricle dret (TSVD).Objectiu: comparar diferents parà metres ecocardiogrà fics amb la RMN en malalts amb TF i IP severa. Resultats: L´excursió de l´anell tricuspidi i el valor de la ona S per Doppler tissular no es correlacionen amb la FE de VD calculada per RMN (FEVD). L´à rea fraccional a l´eix curt mostra una tendència no significativa (p=0,07) a correlacionarse amb la FEVD. Conclusions: els parà metres ecocardiogrà fics que inclouen el TSVD mostren una tendència a correlacionarse amb la FEVD, al contrari dels parà metres de l´anell tricuspidi.
