    Seafood consumers engagement in reducing environmental impacts from packaging

    Packaging is essential to protect food, inform consumers, and avoid food waste, yet it can also contribute to the environmental footprint of products. Recycling waste treatment potentially provides more environmental benefits than other options (e.g., landfill), but only 66 % of packaging waste goes to recycling in the European Union. However, the prevention of packaging production with greater reuse, while extending the lifetime or improving packaging design should be firstly encouraged. This highlights the need to assess the willingness of consumers in reducing the environmental impact of seafood products from packaging. An online questionnaire was conducted in three countries (Portugal, Spain, and Ireland), composed of four sections: (i) seafood consumption, (ii) waste separation to be sent recycling, (iii) willingness to purchase seafood products with packaging designed to reduce environmental impact, and (iv) sociodemographic characteristics. Findings revealed that respondents from Spain and Portugal reported a slightly higher frequency of waste sent to recycle compared to Ireland. Irish respondents appear to have more difficulties about the type of plastic materials that can be sent to recycling due to Irish waste management capabilities; whereas Spanish and Portuguese respondents were not fully aware that packaging does not need to be washed prior to recycling. The most popular alternatives to improve the sustainability of seafood packaging were the use of reusable packaging, compostable packaging material, glass jars for canned seafood instead of cans, and intelligent packaging. Most respondents were willing to pay more for seafood products that use more sustainable packaging (62 % for Spain, 68 % for Ireland, 70 % for Portugal) and half of the respondents intimated that they avoid seafood products due to excessive packaging. With more detailed information on the waste management of packaging, seafood consumers could actively contribute with their attitudes where commensurate changes can improve environmental assessment of seafood.This work was supported by the NEPTUNUS project (EAPA_576/2018).

    OBJETIVO: Verificar a associação da força muscular respiratória com a capacidade funcional, força proximal de membros inferiores e variáveis bioquímicas em pacientes em hemodiálise (HD). MÉTODOS: Participaram deste estudo 30 indivíduos (18 homens), com 53,4 ± 12,9 anos e tempo de HD de 41,1 ± 55,7 meses. Foram avaliados pressão inspiratória máxima (PImax), pressão expiratória máxima (PEmax), distância percorrida no teste de caminhada de seis minutos (6MWT), número de repetições no teste de sentar-e-levantar em 30 segundos (TSL) e registrados os exames bioquímicos de rotina no serviço. RESULTADOS: Houve diminuição da PEmax em relação aos valores preditos (p = 0,015) e redução na distância percorrida no 6MWT quando comparados com equações de predição (p < 0,001). O logPImax e o logPEmax correlacionaram-se com o número de repetições no TSL (r = 0,476, p = 0,008; r = 0,540, p = 0,002, respectivamente), e com os níveis séricos de fósforo (r = 0,422, p = 0,020; r = 0,639, p < 0,001, respectivamente). A distância no 6MWT correlacionou-se com o logPEmax (r = 0,511; p = 0,004) e com o número de repetições no TSL (r = 0,561; p = 0,001). CONCLUSÃO: A redução da PEmax em pacientes com IRT em HD está associada à capacidade funcional, força proximal de membros inferiores e níveis de fósforo sérico, podendo representar, pelo menos em parte, o baixo desempenho físico-funcional desses pacientes.OBJECTIVE: to evaluate the association of respiratory muscle strength with functional capacity, lower limb strength and biochemical variables in hemodialysis (HD) patients. METHODS: a cross-sectional study involving 30 patients (18 male), 53.4 ± 12.9 years, 41.1 ± 55.7 months on HD therapy. Maximal inspiratory pressure (PImax),maximal expiratory pressure (PEmax),distance completed in a six-minute walk test (6MWT) and number of repetitions in sit-and-stand test (STST) were evaluated. The biochemical variables were recorded in the database routine work service. RESULTS: LogEPmax and 6MWT values were significantly lower than the predicted values (p = 0.015; p < 0.001, respectively). logPImax and logPEmax were correlated with number of repetitions in STST (r = 0.476, p = 0.008; r = 0.540, p = 0.002, respectively) and with phosphorus blood levels (r = 0.422, p = 0.020; r = 0.639, p < 0.001, respectively). 6MWT was correlated with logPEmax (r = 0.511; p = 0.004) and with number of repetitions in STST (r = 0.561; p = 0.001). CONCLUSION: PEmax reduction in patients with ESRD on HD is associated with functional capacity, lower limb strength and phosphorus blood levels, and may at least partly represent the low physical and functional performance of these patients
