A detenção e a criação de animais em explorações caseiras podem representar um risco para a transmissão de agentes patogénicos zoonóticos e de genes de resistência a antibióticos, com impacto na saúde pública. Em Portugal, a ausência de registo de sistemas de produção caseira (SPC) dificulta a caracterização das práticas de gestão e criação de animais, assim como o perfil dos seus proprietários. Este estudo pil...
Background: Foodborne diseases are a serious public health concern, and food-producing animals are a major source of contamination. Methods: The present study analysed Escherichia coli and Salmonella spp. isolated from faecal samples of 100 fattening pigs and from 52 samples of pork meat. Results: The results showed that the majority of the analysed meat samples were considered satisfactory in terms of microbio...
Objectives: To assess the role of food-producing animals as potential transmission vehicles of Salmonella spp. and E. coli to Humans, in order to understand the epidemiology and population structure of these zoonotic agents in Portugal.

The appearance of Klebsiella pneumoniae strains producing extended-spectrum β-lactamase (ESBL), and carbapenemase (KPC) has turned into a significant public health issue. ESBL- and KPC-producing K. pneumoniae’s ability to form biofilms is a significant concern as it can promote the spread of antibiotic resistance and prolong infections in healthcare facilities. A total of 45 K. pneumoniae strains were isolated ...
Escherichia coli are facultative, anaerobic Gram-negative rods with many facets. Within resistant bacterial populations, they play an important ecological role and can be used as a bioindicator of antimicrobial resistance. All animal species used for food production, as well as humans, carry E. coli in their intestinal tracts; plus, the genetic flexibility and adaptability of this bacteria to constantly changin...
A fenilcetonúria (PKU) é uma doença genética autossómica recessiva, devido a um erro hereditário do metabolismo dos aminoácidos. A PKU caracteriza-se por um aumento de fenilalanina, em resultado de uma deficiência da enzima hepática, fenilalanina hidroxilase (PAH), uma enzima codificada pelo gene PAH. É uma das 26 patologias integradas no painel das doenças rastreadas em Portugal, a partir de sangue colhido em ...
A cistinose é uma doença metabólica multisistémica, autossómica recessiva caracterizada por uma acumulação de cistina em diferentes órgãos e tecidos devido a uma deficiência no transporte de cistina para o exterior dos lisossomas. O gene responsável pela doença, CTNS, está localizado no cromossoma 17 e codifica para uma proteína de membrana lisossomal, a cistinosina. Neste trabalho foram estudados doentes não r...
Background: Cystinosis is a multisystemic autosomal recessive deficiency of the lysosomal membrane transporter protein (cystinosin) caused by mutations in CTNS gene. Objective : This study summarizes the Portuguese experience in the diagnosis and management of patients with this rare disease over the past few years and reports recurrent mutations in the CTNS gene . Methods : Unrelated patients from different pe...
Introduction: The outcomes of cardiovascular disease are consistently worse among women, regardless of age or disease severity. Such trend might arise from psychosocial factors, which should be examined in this population.Objective: To evaluate the influence of type-D personality on anxiety and depression symptoms reported by female patients after a first acute coronary syndrome.Material and Methods: As part of...
