Physical activity during pregnancy: associations between levels and types of physical activity and low back pain–related disability in portuguese pregnant women
Publication . Teixeira, Isabel; Santos, Paula Clara; Festas, Clarinda; Bernardo, Diana
Low back pain (LBP) is one of the most prevalent musculoskeletal conditions during pregnancy and frequently impairs daily living activities and quality of life. The association between different levels and types of physical activity (PA) and LBP-related functional disability remains insufficiently explored. This study aimed to examine the association between PA levels and types and functional disability among pregnant women with LBP. A cross-sectional analytical study was conducted involving 192 Portuguese pregnant women. Data were collected through an online questionnaire comprising the Pregnancy Physical Activity Questionnaire and the Oswestry Disability Index (ODI). Most participants engaged predominantly in light-intensity or sedentary activity (69.1%), with minimal participation in vigorous activity (0.8%). Functional disability was generally mild (mean ODI = 11.5 ± 7.35); however, 42.2% of participants reported moderate disability and 11.0% severe disability. Advancing gestational age showed weak associations with increased domestic activity (r = 0.146, p = 0.044), decreased occupational activity (r = −0.295, p = 0.001), and higher functional disability scores (r = 0.142, p = 0.049). Parity was associated with differences in total PA levels (p = 0.005) and domestic activity (p = 0.001). Higher ODI scores were weakly associated with light-intensity and sedentary activity (r = 0.144, p = 0.047), whereas severe disability demonstrated a moderate association with sedentary behavior (r = 0.529, p = 0.014). Overall, lower levels of PA, particularly sedentary behavior, were weakly associated with higher LBP-related disability; however, the observed associations were generally weak and should be interpreted with caution considering the cross-sectional design.
Estimulação multissensorial nas AVDs
Publication . Carmo, Daniela; Lameirinhas, Maria Beatriz; Anes, Eugénia; Galvão, Ana Maria
Nos idosos que apresentam perda de capacidades funcionais, a estimulação sensorial é essencial. Esta estimulação pode ser efetuada através de programas de forma coordenada. Um programa de estimulação multissensorial consiste num combinado de ações que objetivam levar os idosos a experienciarem, sentirem, perceberem, interiorizarem e identificarem as sensações a partir do seu corpo. Objetivo: Esta pesquisa objetiva perceber de que forma a estimulação multissensorial nas atividades de vida diária pode contribuir para a melhoria da qualidade de vida das pessoas idosas. Metodologia: Foi efetuada uma revisão narrativa. Foram utilizados como descritores a estimulação multissensorial, idosos e atividades de vida diária. A pesquisa foi efetuada no Google Académico, da qual 4 artigos obedeciam aos critérios estabelecidos, integrando o presente estudo. Resultados: A investigação demonstrou que a estimulação multissensorial exibiu significativas melhorias a nível da orientação espaciotemporal e das funções cognitivas e sensoriais dos participantes, com resultados benéficos a nível da capacidade de memorização auditiva e visual. Foi demonstrado ainda uma diminuição dos comportamentos disruptivos, bem como um aumento da socialização, capacidade de comunicação e diminuição dos níveis de ansiedade. Conclusão: Pode-se concluir efetivamente que a estimulação multissensorial tem um impacto positivo nas atividades de vida diária, contribuindo para a melhoria da qualidade de vida do idoso. Estes resultados contribuem para uma efetiva tomada de decisão, no sentido de melhor contribuir para dar qualidade de vida aos anos ganhos.
Post-treatment Modification Using Deep Eutectic Solvent in PES and PES/ SAPO-34 Membranes for Gas Separation
Publication . Cardoso, Jonathan S.; Lin, Zhi; Brito, Paulo; Ferreira, Licínio
Mixed matrix membranes (MMM) are heavily studied and the main concern by researchers is the difficulty to obtain a high selectivity membrane with low defects, mainly interfacial voids due to the poor interaction between polymer matrix and filler. The functionalization of zeolite surface in PolyEtherSulphone (PES)/ Silico-AluminoPhosphate-34 (SAPO-34) led to membranes with higher compati-bility. Recently, the use of ionic liquids in the particles surface to improve the gas permeability and separation efficiency has presented advanced results. Although, the cost and environmental issues on Ionic Liquids (ILs) still represent a limit to its use. The Deep Eutectic Solvents (DESs) present an alternative route to replace ILs, with low-cost and environmentally friend. This paper aims to study the potential use of choline chloride/urea, a DES mixture, in ratio 1:2, to replace ILs as a post-healing methodology, showing a 20% increase in CO2 permeability in PES membranes and 15% increase in CO2/N2 selectivity in PES/SAPO-34 membranes due to an increase in compatibility between polymer and zeolite promoted by the post-treatment using DES.
Let´s get inclusive

In Portugal, higher education has been undergoing changes related to globalization and
democratization of access on the one hand and, on the other hand, to the expansion and diversification of the training offer. The increase in the number of foreign students brings greater diversity in terms of their individual, social, economic and cultural characteristics. Figures made available to Lusa by the Ministry of Science, Technology and Higher Education, confirm that the number of PALOP students has increased by 170% in five years, from 7.355 to almost 19.993, The number of students from Portuguese-speaking African countries in higher education in Portugal has almost tripled in five years, but many face difficulties and there are high levels of dropouts, warns Miguel Chaves from the New University of Lisbon, stressing that the communication difficulties of these students are reflected in a "big problem", namely in terms of academic success. With diversity comes new challenges, which include: a greater demand to ensure effective higher education for all; the need for culturally inclusive and responsive teaching, with a focus on promoting equity, equality, and respect for diversity; and creating a space that allows different people to learn differently [1]. The challenge: to highlight the need to provide sustainable psychosocial support to students from PALOP countries. The approach and process: the approach was based on the Design thinking (DT) process [2]. It took place over the course of a semester. DT is a humanistic approach to innovation and creativity and in this project, the process focused on the students Stakeholders), starting with a deep empathy and discovery of needs in terms of mental health and well-being issues; difficulties encountered in the IPB platform depending on the needs and motivations of the students [3]. The result achieved: in order to raise awareness among IPB managers, the project was presented to the IPB board and academic services. The need for an up-to-date, intuitive platform with clear communication was highlighted, both for academic aspects and for support in the health area. Based on the report, two part-time medical doctors were hired. The next steps planned: it is our goal to contribute to a healthy and happy academic environment, with emphasis on the area of psychological and social well-being.
