- Health literacy in Portugal: results of the health literacy population survey project 2019–2021Publication . Arriaga, Miguel; Francisco, Rita; Oliveira, Jorge; Silva, Carlota; Câmara, Gisele; Sørensen, Khristine; Dietscher, Christina; Costa, AndreiaHealth literacy entails the knowledge, motivation, and competencies to access, understand, appraise, and apply health information in order to make judgments and decisions in everyday life concerning health care, disease prevention, and health promotion to maintain or improve quality of life throughout the life course. It has become an essential concept in public health. It is considered a modifiable determinant of health decisions, health behaviors, health, and healthcare outcomes. Prior studies suggest highly variable levels of health literacy across European countries. Assessing and monitoring health literacy is critical to support interventions and policies to improve health literacy. This study aimed to describe the process of adaptation to Portugal of the short‐form version of the Health Literacy Survey (HLS19‐Q12) from the Health Literacy Population Survey Project 2019–2021, also establishing the health literacy levels in the Portuguese population. The sample comprised 1247 valid cases. The survey consisted of a brief questionnaire on the determinants of health literacy, plus the HLS19‐Q12 questionnaire and the specific health literacies packages on digital health literacy, navigational health literacy, and vaccination health literacy. The results suggest that 7 out of 10 people in Portugal (mainland) have high health literacy levels and support the results of other studies concerning the main socioeconomic determinants of general health literacy. Furthermore, the results suggest that “navigation in the health system” tasks are the most challenging tasks regarding specific health literacies. The overall data suggest the HLS19‐Q12 as a feasible measure to assess health literacy in the Portuguese population. Thus, it can be used in Portugal to assess the population’s needs and monitor and evaluate policies and initiatives to promote health literacy by addressing its societal, environmental, personal, and situational modifiable determinant factors.

- Prevenção de Úlceras de Pressão na posição de sentado: indicações práticasPublication . Alves, Paulo; Oliveira, Jorge; Dias, Vanessa; Mota, FilomenaAs úlceras de pressão são um dos problemas mais comuns dos sistemas nacionais de saúde, que afecta milhões de doentes e está associado a elevados custos de prevenção e tratamento. São feridas associadas maioritariamente aos doentes acamados, no entanto, os indivíduos de cadeira de rodas ou que passam longos períodos na posição de sentado, sem se mobilizarem, estão em elevado risco de as desenvolver. Elementos-chave na prevenção de úlceras de pressão são a seleção de superfícies de apoio e posicionamentos adequados ao indivíduo sentado. No entanto, existe pouca orientação nesta área que permita ao profissional encontrar respostas para planear as suas intervenções. Nem sempre os profissionais têm os recursos materiais e humanos suficientes para realizar intervenções ajustadas. O objectivo deste artigo é identificar na literatura recomendações que contribuam para um ambiente em que beneficie a viabilidade dos tecidos, evitando a lesão tecidular e contribuindo para o processo de cicatrização no doente sentado. Identificar estratégias de prevenção, dando especial relevo aos posicionamentos e às superfícies de redistribuição de pressão. Esta preocupação surge no contexto das mais diversas realidades, o que fez com que a Tissue Viability Society realizasse directrizes clínicas dirigidas para a prevenção das úlceras de pressão no doente sentado, a fim de minimizar este flagelo. As úlceras de pressão são frequentes na aposição de sentado, e levam a diversas complicações, como osteomielite, septicemia, e podem mesmo levar à morte.
- A quantitative approach to assess the contribution of seals to the permeability of water vapour and oxygen in thermosealed packagesPublication . Reinas, Isabel; Oliveira, Jorge; Pereira, Joel; Mahajan, Pramod; Poças, Maria de FátimaShelf-life of many foods is largely dependent on the barrier to moisture and oxygen of the respective package. Barrier is often assessed by measuring the transmission rate of films. However, in thermosealed packages leaks and weak seals can give rise to increased total mass transfer entering the system and reaching the food. While leaks are random defects and are associated to early failure, lower integrity of regular seals tends to affect whole batch causing a decrease in the product shelf-life. In the present work the contribution of the seals to total permeability of packages was assessed by measuring transmission rate of the film and of thermosealed packages of different sizes, therefore with different seals length. Packages made of PA/PE and PVDC coated PET/PE and their respective films were tested for moisture and oxygen transmission rate at different temperature and relative humidity. Results indicate that industrial regular produced seals can account for ca. 25% of the total mass transfer through the system. This decrease of the package barrier as compared to the material barrier will have a significant impact on the product shelf-life and it should be considered in the packaging design process.
