- “Alimentos PT.ON.DATA” - Information Management System for The Analytical Data of Food Chain Official ControlPublication . Mascarenhas, Fernanda; Inácio, Patrícia; Viegas, Silvia; Costa, José Manuel; Ravasco, Francisco; Tomé, Sidney; Parreira, Diana; Azevedo, Ana; Brazão, Roberto; Oliveira, LuísaBACKGROUND: According to Article 33 of the Regulation (EC) 178/2002, Member States shall take the necessary measures to enable the transmission to EFSA of the data they collect in the fields of (a) food consumption and the exposure of individuals to risks related to the consumption of food; (b) incidence and prevalence of biological risk; (c) contaminants in food and feed; (d) residues. In addition, specific EU legislation on data collection exists for specific data collection domains, namely, pesticides, contaminants and zoonoses and zoonotic agents, specifying that the data from official control should be reported to EFSA. According to EFSA mission under Article 36 of the above mentioned regulation, the development and implementation of joint projects for promoting European networking is foreseen. Within this task, Portugal has developed in 2011, a national information management system “alimentos PT.ON.DATA” for chemical contaminants and is currently upgrading the system for food additives, pesticide residues, zoonotic agents and residues of veterinary medicinal products.
- Atypical adult-onset methylmalonic acidemia and homocystinuria presenting as hemolytic uremic syndromePublication . Navarro, David; Azevedo, Ana; Sequeira, Sílvia; Ferreira, Ana Carina; Carvalho, Fernanda; Fidalgo, Teresa; Vilarinho, Laura; Santos, Maria Céu; Calado, Joaquim; Nolasco, FernandoThrombotic microangiopathy (TMA) syndromes can be secondary to a multitude of different diseases. Most can be identified with a systematic approach and, when excluded, TMA is generally attributed to a dysregulation in the activity of the complement alternative pathways-atypical hemolytic uremic syndrome (aHUS). We present a challenging case of a 19-year-old woman who presented with thrombotic microangiopathy, which was found to be caused by methylmalonic acidemia and homocystinuria, a rare vitamin B12 metabolism deficiency. To our knowledge, this is the first time that an adult-onset methylmalonic acidemia and homocystinuria presents as TMA preceding CNS involvement.
- Pilot project on the implementation of SSD2 in the frame of the electronic transmission of harmonised data collection of analytical results to EFSAPublication . Ravasco, Francisco; Tomé, Sidney; Azevedo, Ana; Inácio, Patrícia; Oliveira, LuísaThe present report describes the work done in Portugal under the Pilot project on the implementation of SSD2 in the frame of the electronic transmission of harmonised data collection of analytical results to EFSA and corresponds to deliverable D6 “Report on SSD2 pilot results”. This document describes all the procedure to the encoding and mapping for the chemical contaminants, pesticide residues, biological monitoring and food additives data from the Portuguese authorities, how that correspondence is made for the Standard Sample Description ver.2 (SSD2), the transformations required to support the controlled terminology supplied by EFSA, the transformation made on the national database PT.ON.DATA to support the new domains and the SSD2 languages. This document describes also the challenges encountered during the implementation of the standard model and makes a general analysis on its limitations and potential developments.

Parreira, Diana; Azevedo, Ana; Tomé, Sidney; Ravasco, Francisco; Mascarenhas, Fernanda; Viegas, Silvia; Brazão, Roberto; Oliveira, LuisaEnquadramento: A EFSA foi criada com o Regulamento (CE) n.º 178/2002 com o objetivo de recolher e analisar dados que permitam a caracterização e o controlo dos riscos que tenham impacto direto ou indireto na segurança dos géneros alimentícios ou dos alimentos para animais (ponto 4 do Art. 22º). Avaliação do risco efetuada pela EFSA depende: • Utilização de toda a variedade de recursos especializados disponíveis; • Qualidade, consistência, atualidade e integridade dos dados utilizados nas análises científicas; • Monitorização dos riscos; • Considerações sobre os riscos em avaliação.
