Introduction: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portuguese population. Materials and methods: We developed a cross-sectional study based on a convenience sample of 626 sera collected during June 2014, covering all age groups, both gender and all administrative health regions of Portugal. Sera antibody titers for seasonal and new A(H3) drift influenza virus were evaluated by hemagglutination inhibition assay (HI). Seroprevalence to each seasonal influenza vaccine strain virus and to the new A(H3) drift circulating strain was estimated by age group, gender and region and compared with seasonal influenza-like illness (ILI) incidence rates before and after the study period. Results: Our findings suggest that seroprevalences of influenza A(H3) (39.9%; 95% CI: 36.2-43.8) and A (H1)pdm09 (29.7%; 95% CI: 26.3-33.4) antibodies were higher than for influenza B, in line with high ILI incidence rates for A(H3) followed by A(H1)pdm09, during 2013/2014 season.

Objetivo: identificar a percepção do condutor acidentado sobre os fatores que influenciaram no acidente motociclístico. Método: pesquisa descritiva, qualitativa, desenvolvida no mês de setembro de 2015, com quinze pessoas acidentadas, que conduziam a motocicleta no momento do acidente, na capital do Estado do Piauí. Os dados foram analisados pela técnica de análise temática. Resultados: emergiram neste estudo três categorias: percepção das vítimas de acidente motociclístico quanto ao seu comportamento de risco; associação do acidente ao comportamento de risco do outro condutor; e fatores externos relacionados ao acidente do motociclista na concepção do condutor acidentado. Considerações finais: Evidenciaram-se dois grandes desafios do poder público: instituir uma educação no trânsito tão eficaz quanto a política de venda de motocicletas e, envolver a sociedade em debates sobre os problemas que ocorrem no trânsito.

This chapter analyses Repair Café Porto (RCP) through the lens of a SWOT (strengths, weaknesses, opportunities, threats) method. It is based on the event-RCP held for three hours on a Saturday every two months from June 17, 2017 until April 28, 2018 and on a new economics approach of circular economy. It is intended to examine the potentialities and challenges of RCP. Repair Cafés are ‘workshops' for people to bring consumer products in need of repair where they with volunteer fixers learn repair, maintain their broken or faulty products, or try product modification. It is an RCP-requirement that visitors who bring products participate in repairs undertaken. Regular repair stations include bike, electrical and electronic, clothing, and jewellery. The SWOT method is used to assess internal and external aspects of RCP. It is concluded that the success of RCP is dependent on financial support, the maturity of repair notion, and the alteration of consumers and producers' attitudes to see waste as a resource and to extend the life of a product.
