6 pages, 4 tables, 1 figure.-- Under a Creative Commons license, Listeria monocytogenes is a major foodborne pathogen which mainly infects susceptible individuals through the consumption of contaminated foods. To this end, ready-to-eat (RTE) food products are of particular concern as this microorganism is widely distributed, can survive, and even grow, under adverse conditions, and thus must be carefully controlled. In the present study, an interlaboratory ring trial was organized to evaluate an open formula qPCR-based method for the detection of L. monocytogenes. The molecular method was evaluated on a novel RTE seafood product, developed in the framework of a European project, the SEAFOODAGE (EAPA_758/2018). Six laboratories located in Spain and Portugal participated in the study, and the results obtained indicated that this new method presented high diagnostic sensitivity (100%) reaching a low limit of detection (, This work was financially supported by the Seafood Age project, which was co-financed by the Interreg Atlantic Area Program (EAPA_758/2018) though the European Development Fund (ERDF).

Primary cystic pancreatic neoplasms are rare tumors, with an approximate prevalence of 10% of cystic pancreatic lesions. Most of these lesions correspond to mucinous cystic neoplasm, serous cystoadenoma and intraductal papillary mucinous tumor (IPMT). IPMT is characterized by diffuse dilatation of the main pancreatic duct and/or side branches with inner defects related to mucin or tumor, or mucin extrusion from a patent ampulla. IPMT has a low potential for malignancy, with a low growth rate, a low rate of metastatic spread and postsurgical recurrence. Over the last few years, major advances have been made in the diagnostic and therapeutic management of this tumor.
