Prévalence de pathogènes humains dans les sols français, effet des facteurs pédoclimatiques, biologiques et du mode d'utilisation des sols
2013
Soil contamination by bacterial pathogens can occur through manure, sewage sludge spreading or irrigation using waste water treatment plants effluents. Agricultural soils may act as reservoirs for these pathogens, play a significant role in their dissemination, leading to the potential contamination of food and water resources. Health risk associated with the occurrence of pathogens in environmental matrices has to be thoroughly evaluated. In this context, the objectives of this work were: i) to determine the prevalence of two pathogenic bacterial species (Listeria monocytogenes and Enterococcus faecalis) in a large collection of French soils originated from a systematic soil survey of the …

Facteurs épidémiologiques influençant la survie dans le lymphome à cellules du manteau
2017
Mantle Cell Lymphoma (MCL) is a recently defined entity, typically characterised by the genetic translocation t(11 ;14)(q13 ;q32) and counting for 2 - 10% of all non-Hodgkin Lymphomas. With a median survival between 3 and 5 years after diagnosis, MCL is an agressive disease and despite the recent therapeutic advances little in know about its prognostic factors. Some studies had investigated clinicopathological features and new treatment strategies, but there is a lack of knowledge regarding the impact of lifestyle and environnemental factors on outcome of MCL patients. From 2008 to 2012, the LYSA Group conducted in France two prospective multi center clinical trials on MCL : LM manteau 2010…
Prognosis of resected intrahepatic cholangiocarcinoma
2017
Introduction. Complete resection stands as the only curative option for intrahepatic cholangiocarcinoma (IHCC). Still, prognosis remains poor after resection due to a recurrence rate over 60% leading to actual 5-year survival rates below 20%. Reliable prognostic estimation and better understanding of tumor biology would be of interest for improving IHCC prognosis.Methods. Using clinical and biological data from two large cohort of resected IHCC (MSKCC, n=189 and AFC, n=522), three objectives have been explored. First, assessing the performances of different published prognostic models. Second, defining the reliability of preoperative prognostic estimation using imaging, tumoral genomic prof…
Retos en la internacionalización y supervivencia de los nuevos emprendimientos manufactureros
2015
El objetivo de este trabajo es analizar la relación entre la orientación internacional y la supervivencia de empresas manufactureras de reciente creación. Para ello se estudió una muestra de 2.975 nuevos emprendimientos constituidos durante el período 2001-2010 en la industria textil-confección de España. Metodológicamente, se han empleado modelos de duración mediante regresiones de Cox, que modelizan el riesgo relativo asociado con una variable en función del tiempo transcurrido hasta que sucede el evento. Los principales resultados evidencian que la internacionalización de los nuevos emprendimientos es una condición necesaria aunque no suficiente para sobrevivir en una industria globaliza…
