- Brincar e desenvolvimento infantil dos 0 aos 3 mesesPublication . Festas, C.; Ferreira, R.Enquadramento: A criança, como ser em desenvolvimento, tem direito a que lhe sejam proporcionadas condições favoráveis a um desenvolvimento global, o mais harmonioso possível. Na primeira infância, dos 0 aos 3 anos, o desenvolvimento infantil é diretamente influenciado pela qualidade de vida da criança. Deste modo, é importante conhecer estratégias que sejam promotoras do melhor desenvolvimento infantil possível, havendo consenso de que o brincar é uma das principais atividades para esse progresso. Objetivo: Identificar de que forma o brincar pode promover o desenvolvimento infantil. Metodologia: Realização de uma revisão da literatura através de pesquisa na base de dados BVS, utilizando descritores em Ciências da Saúde, identificando artigos publicados em inglês e português, com texto integral disponível, os quais foram posteriormente sujeitos a um processo de seleção. Resultados: Após o processo de seleção foram analisados 7 artigos, entre eles ensaios randomizados, revisões sistemáticas, estudos exploratórios transversais e estudos quantitativos, que relacionam o brincar, com o desenvolvimento infantil das crianças na primeira infância. O conteúdo dos artigos abrange a análise do brincar no ambiente familiar, as interações entre crianças e os seus pais e o uso do brincar como promotor do desenvolvimento, destacando os efeitos cognitivos, afetivos e comunicacionais e a sua importância como ferramenta de aprendizagem. Os estudos evidenciam também, que a presença de adultos, concretamente dos pais no brincar, é de primordial importância na interação com as crianças e por isso mais influenciadora do que a própria brincadeira, na estimulação do desenvolvimento infantil. Conclusões: A promoção do desenvolvimento infantil na primeira infância, é essencial para o desenvolvimento da criança, e terá um grande impacto na sua vida futura. Os artigos analisados mostram que, o brincar tem várias funções que estão relacionadas com o desenvolvimento da criança tanto a nível físico, como cognitivo e social As brincadeiras e formas de brincar, que os pais podem desenvolver com os filhos, têm uma grande influência na promoção de uma variedade de domínios do desenvolvimento da criança, mas a qualidade da interação interpessoal que se estabelece ao brincar com a criança, é muito mais relevante que a própria brincadeira ou o tipo de brinquedos que lhe são oferecidos.
- Effect of the pH of growth on the survival of Lactobacillus delbrueckii subsp. bulgaricus to stress conditions during spray-dryingPublication . Silva, J.; Carvalho, A. S.; Ferreira, R.; Vitorino, R.; Amado, F.; Domingues, P.; Teixeira, P.; Gibbs, P. A.Aims: The aim of this study was to optimize survival of Lactobacillus delbrueckii subsp. bulgaricus during spraydrying and subsequent storage through optimizing the pH of growth conditions. Methods and Results: Cell concentrates previously grown without or with pH controlled were spray-dried and stored at 20ºC and heat treated at 57ºC. Cells grown under noncontrolled pH were more resistant to both drying and heating than cells grown under controlled pH but no significant differences were observed during storage. The intracellular proteins profile of cells grown under both conditions was studied by two-dimensional SDS-polyacrylamide gel electrophoresis. Eight proteins were identified using automated mass spectrometry (MS) and tandem mass spectrometry (MS/MS) data acquisition. Of the identified proteins, only cochaperonin GroES corresponded to a known heat shock protein (HSP). The other proteins identified are proteins involved in glycolysis. For cells grown under noncontrolled pH the expression of the Hsp70, GroES and GroEL, measured by Western blotting, was enhanced. Conclusions: The higher resistance of cells grown under noncontrolled pH correlates with the enhanced production of heat shock proteins. Significance and Impact of the Study: Growth of L. bulgaricus under controlled pH (commonly used by the starter cultures production industry) results in cells more sensitive to stresses frequently encountered by the cells during starter cultures preparation/storage/utilization.
- Overview of clams packaging systems sustainabilityPublication . Carneiro, A.; Goes, C. B.; Mota, I.; Ferreira, R.; Cruz, A.; Marcos, Begonya; Sivertsvik, M.; Poças, F.Background: This work analyses the protection requirements and options for primary and transportation packaging of shellfish. It considers the properties of materials and the most recent developments and innovations in the arena created by legislation shaping packaging practices and frameworks of circularity and sustainability. A short review of the environmental profiles of typical packaging systems is provided. Fresh clams must be alive when sold, and the shelf-life period is defined based on the time the clams are alive. This product is highly perishable and valued, and losses and waste must be reduced. Scope and approach: a multidisciplinary approach was followed, bringing together data from the product, material properties, and packaging design. These were integrated in the analysis of the impact of non-fossil plastic alternatives, reusability, recyclability and incorporation of recycled in the clams packaging. This work provides a global view of the packaging system, focusing not only on the materials developments but also on the trends regarding primary packaging, labels, and secondary packaging for transport. Scientific reports from the last 10 years were used as well as an interview with major stakeholders in Europe (a retailer and a packaging supplier). Key findings and conclusions: there are a large body of research dedicated to studying the shelf-life of other bivalves, but studies focusing on clams are scarce. Furthermore, many studies do not consider the FAO recommendations on the need to keep the clams alive up to the purchasing time, and therefore conclusions are biased because they are based on monitoring parameters that are less relevant for this product. Novel packaging materials, such as bioplastics and bio-polymers functionalised with smart components seem very attractive and they have been targeted in several reviews and many published studies. However, results reported show that there is a gap between the performance required and effectively delivered by many of these new developed materials. Much less effort has been dedicated to optimising the more traditional materials, to improve their recyclability, thereby extending the usage cycle to save resources. This research need has been clearly identified for transportation packaging, particularly foamed materials, crucial for thermal insulation, and for nets used for primary packaging of bivalves. Optimisation of the mechanical properties under humid conditions are needed to permit the use of biobased materials, such as cellulosic fibres, as clams nets. MAP technology is not a sustainable solution for increasing the shelf-life of clams. The barrier materials required and the limited recyclability represent an unbalanced environmental impact. A critical analysis of the environmental profiles associated with different packaging systems highlights challenges and opportunities within the industry when addressing sustainability. This review provides insights into current trends, challenges, and future directions in clams packaging, promoting informed decision-making and fostering sustainable practices in the packaging industry.
- The child/family. The centrality of carePublication . Ferreira, R.; Goncalves, J.; Sousa, H.; Amendoeira, J.; Silva, M.Introduction The centrality of health care to the child emerges in the family. Decision-making results from this partnership, with results in health promotion and disease prevention. The nurse identifies a set of resources and strategies that constitute literacy and health gains. Objectives Map evidence related to nurses’ strategies in child/family care delivery. Methods Development of Scoping review according to Joanna Briggs Institute (JBI) with the question: "What strategies do nurses use in child care?’’ The population selected, children up to 18 years of age; concepts: nursing, patient-centred care, outcome assessment and family nursing; context: where the child / family is located. The search expression: "Patient-centered care" AND "family nursing" OR "Outcome assessment". All MeSH descriptors. Research on the EBSCOhost platform (CINAHL, MedicLatina, Medline and Nursing & Allied Health Database) and in the database: PubMed. 5-year chronological drawing (2014-2018). With PRISMA (JBI), we have included 12 articles. We mobilized the Data Extraction to systematize the results with methodological quality, ensuring their congruence with the revision question. Results The centrality of care in the family promotes literacy. Strategies included the presence, participation, collaborative work, evaluation and empowerment of the family/child, with results centered on health literacy. The promotion of sleep quality/ mood of the parents; systematic evaluation for individualized family/quality of life interventions; strengthening of coping mechanisms; family uniqueness; parental involvement in care; involvement and identification by the family/child promotes their literacy.
