First evidence of Schmallenberg virus introduction in Portugal, 2014

Objectives: Serra da Estrela native (SEN) breed of sheep is one of the most important in Portugal, standing responsible for the production of one of the most internationally recognized cheeses in the world, "Queijo Serra da Estrela” (protected designation of origin). One of the major risks to the sustainability of SEN dairy flocks if footrot, an infectious diseases that causes lameness, decrease in milk production, weight loss and decrease in fertility. The aim of this work was to determine which parameters become decisive for the appearance of footrot in SEN dairy flocks, while establishing associations with environmental and nutritional variables. Materials and Methods: The present study was carried out by performing an especially designed 27 multiple choice questionnaire, based on the underlying causes of lameness in livestock and in the clinical diagnosis performed by the vet techinichian of the clinical cases evaluated at the moment of the inquiry. The survey was performed during the execution of the oficial veterinary health program between February and September of 2014 by a veterinarian team from the Association of SEN Sheep Breeders (ANCOSE). The ovine producers (N=30, with a total of 1270 animals) were randomly selected from the extense area of production of “Queijo Serra da Estrela”. The parameters evaluated in the study were: season and consequent weather changes during the period of the study, floor types, hygiene conditions, bed types, the existence and use of footbaths, location of footbaths, foot trimming and foot hygiene procedures. After the construction of the database and using the Statistical Package for Social Sciences version 16.0 the frequency response for each item was calculated. Results: All SEN livestock producers are proactive in the treatment of lameness (70%). About 99.7% of lameness was related with footroot and most appeared in winter (36.7%). In some occasions there was not a specific season distribution (56.7% rainiest years). From the analyzed farms, 70% use straw as a floor bed, followed by bush (21%). 45.6% of animals were clinically diagnosed with footrot and were sheltered in straw floor. Bed quality is good in 40%, however frequent changes in the floor bed in the preceding 15 days had a higher rate of footroot diagnosed cases (33,23%) compared to monthly changes. Regarding sheepfold animal number, the distribution is proper in 36.7%, elevated in 30%, overcrowded in 6.7% and low in 23.3%. Clinically ill diagnosed animals in last category were the lowest observed (3%). Concerning hoof trimming, 76.7% trims while 23.3% reported not to perform that task. From those that perform trimming, 73.9% do it only when necessary, 21.7% at the time of clipping and 4.4% when the animal is affected. One curious result was that animals who perform trimming at clipping had higher footrot cases (52.6%), unlike those who trim only when necessary (40.2%) or even when animals are clinically ill (0.91%). Mostly all in the presence of footrot choose a local treatment (95.2%) using antibiotic sprays, instead of parenteral antibiotic treatment. Footbath is rarely used in the prevention (13.3%) of this disease and when it is misconceived (25%) and incorrectly formulated (100%). Conclusions: This study was the first performed in Portugal focusing footrot caracterization in native SEN flocks.Economic impact in SEN dairy flocks is atributed to factors such as direct decrease in milk and meat production,early slaughter of affected animals due to non responsive treatment and medical expenses.The most effective eradication method combines first of all the ability to understand the problems of SEN producers and implementation of preventive measures and treatment of footrot.Often linked to lack of formation, the advance age of portuguese producers the mentality and social factors block the advance of veterinarian intervention itself.

Literacia em saúde, dos dados à ação: tradução, validação e aplicação do European Health Literacy Survey em Portugal

Nos últimos anos, diferentes estudos têm demonstrado que um nível inadequado de literacia em saúde pode ter implicac¸ões significativas nos resultados em saúde, na utilizac¸ão dos servic¸os de saúde e, consequentemente, nos gastos em saúde. O conceito de literacia em saúde evoluiu de uma definic¸ão meramente cognitiva para uma definic¸ão que engloba as componentes pessoal e social do indivíduo, assumindo-se como a capacidade de tomar decisões fundamentadas no seu dia-a-dia. O presente estudo transversal analítico teve como objetivo traduzir e validar para a populac¸ão portuguesa o European Health Literacy Survey (HLS-EU). O HLS-EU-PT foi aplicado em todo o território nacional, incluindo as regiões autónomas, através de investigadores de uma rede académica. A recolha de dados foi realizada por entrevista presencial. A amostra final ficou constituída por 1.004 indivíduos com idades ≥ 16 anos. Este estudo disponibilizou o instrumento de avaliac¸ão do nível de literacia para a saúde em Portugal, tão importante na gestão da saúde. O HLS-EU-PT apresenta-se como um instrumento adequado para aferir o nível de literacia em saúde da populac¸ão portuguesa e evidencia propriedades psicométricas comparáveis às versões utilizadas nos outros países. Em Portugal, 61% da populac¸ão inquirida apresenta um nível de literacia geral em saúde problemático ou inadequado, situando-se a média dos 9 países em 49,2%. Relativamente à dimensão cuidados de saúde, apenas 44,2% apresenta um nível suficiente ou excelente de literacia em saúde. No que respeita à prevenc¸ão da doenc¸a, cerca de 45% dos inquiridos revela ter um nível suficiente ou excelente de literacia em saúde, comparativamente com a média dos 9 países, que nesta dimensão apresenta o valor de 54,5%. Na dimensão promoc¸ão da saúde, 60,2% da populac¸ão auscultada apresenta um nível de literacia em saúde problemático ou inadequado, sendo que a média se situa nos 52,1%. Assim, considera-se fundamental e urgente a conceção e implementação de uma estratégia nacional de literacia em saúde.

Prevalence of hepatitis E virus antibodies in workers occupationally exposed to swine in Portugal

The concept of zoonotic hepatitis E in industrialized countries has emerged with the discovery of swine strains of hepatitis E virus (HEV) genotype 3, closely related to human HEV. Different routes of zoonotic HEV transmission have been recognized, including contact with infected pigs. Workers occupationally exposed to swine (WOES) have been considered a risk group for HEV infection, but contradictory results have been reported. In the present study, we searched for anti-HEV IgG in WOES (butchers, slaughterhouse workers, veterinarians and pig farmers; n = 114) and in the general population (n = 804) in order to investigate the potential occupational risk of zoonotic HEV infection in this work group. A significantly higher (p = 0.008) anti-HEV IgG seroprevalence was found in WOES (30.7 %) when compared with the general population (19.9 %). Multivariate analysis showed that having professions with exposure to pigs for more than 16.5 years was a risk factor for being positive for anti-HEV IgG (aOR of 5.4, 95 % CI 1.9-15.6, p = 0.002). To our knowledge, this is the first study on the prevalence of anti-HEV IgG in WOES in Portugal, also showing increased probability for infection in this group.
