Publication . Agradém, Carla; Alves, Sara Elisa Brás; Sá, Leandro Moreira de; Mendes, Eugénia; Azevedo, Ana; Fernandes, Adília; Fernandes, Hélder; Vaz, Josiana A.; Pereira, Ana Maria Geraldes Rodrigues
O envelhecimento populacional representa um desafio crescente para a saúde pública, sobretudo na prevenção e gestão de doenças crónicas. A dieta mediterrânica, reconhecida pelos seus benefícios cardiometabólicos, continua a apresentar níveis reduzidos de adesão em Portugal, especialmente entre a população idosa. O presente estudo deteve como objetivo avaliar o efeito de uma inter-venção educativa nutricional, baseada nos princípios da dieta mediterrânica, na adesão ao padrão alimentar, composição corporal e marcadores bioquímicos de idosos. Trata-se de um estudo quase-experimental, longitudinal, realizado entre abril e junho de 2025, com 11 participantes (≥65 anos; 90.90% mulheres; idade média 70.30 ± 6.30 anos), em Bragança. A adesão à dieta mediterrânica foi avaliada pelo questionário MEDAS; a composição corporal por bioimpedância elétrica; e os marcadores bioquímicos por análise laboratorial. A intervenção incluiu sessões teóricas e práticas, com componentes interativas e sensoriais centradas na dieta mediterrânica. Verificou-se um aumento significativo na adesão à dieta mediterrânica (7.50 ± 2.70 para 9.00 ± 2.10 pontos; p=0.005), bem como reduções significativas na glicemia em jejum (77.80 para 57.50 mg/dL; p<0.001), HbA1c (5.76 para 5.65%; p=0.002) e colesterol total (179.60 para 130.20 mg/dL; p<0.001). Não se observaram alterações significativas na composição corporal, embora participantes com maior adesão tenham eviden-ciado um aumento da massa muscular esquelética. Intervenções educativas nutricionais de caráter prático e interativo demonstram eficácia na melhoria da adesão à dieta mediterrânica e de marca-dores metabólicos em idosos, contribuindo potencialmente para a prevenção de doenças crónicas.
Effect of aromatherapy massage with foeniculum vulgare mill. seed essential oil compared to massage on anxiety, well-being, and sleep quality: an exploratory randomized study
Publication . Félix,Beatriz Pires; Rodrigues, Andreia; Sousa, Maria João; Pereira, Olívia R.
Aromatherapy is a complementary and alternative medicine (CAM) widely used in the management of several mental and physical conditions. The fennel seed essential oil (FEO) has several biological activities and has been reported as potentially beneficial in the management of anxiety and sleep disorders. The present study aimed to evaluate the
effects of aromatherapy massage using FEO compared to massage alone on reducing anxiety and improve sleep quality and overall well ]being.
FEO was extracted by hydrodistillation, and its chemical composition was determined by GC‐MS. In the aromatherapy trial, 40 participants were randomly divided into the “Massage Group” (n = 20) and the “Aroma Massage Group” (n = 20). Individuals in the “Aroma Massage Group” were treated with 1.6% of FEO diluted in sweet almond oil, while the “Massage Group” only received the massage with sweet almond oil. The intervention consisted of one massage session every 15 days over a 2 months period. The questionnaires on anxiety (State‐Trait Anxiety Inventory), sleep quality (Pittsburgh Sleep
Quality), and well‐being (WHO‐Five Well‐Being Index (WHO‐5)) were performed at four different times. Data were analyzed using SPSS software with a significance level of 5%.
The major compound in FEO was trans‐Anethole (78.2%). In the aromatherapy trial, scores on the State Anxiety scale of the State‐Trait Anxiety Inventory (STAI), were significantly lower in the “Aroma Massage Group” compared to “Massage Group” with mean values of 32.47 ± 7.86 and 41.75 ± 11.74, respectively, in Questionnaire 3 (after the last session), corresponding to a difference of −9.28 (p = 0.007). No statistically significant differences were observed over time across the four assessment points, with p = 0.536 for the “Massage Group” and p = 0.381 for the “Aroma Massage Group.” Additionally, the “Aroma Massage Group” showed a higher proportion of individuals reporting strong well‐being (89%) and good sleep (32%) compared to the “Massage Group” (65% and 25%, respectively) in Questionnaire 4 (1 month after the end of the intervention), however, these differences were not statistically significant when considering mean questionnaire scores.
Assessing Nurses’ Job Satisfaction in the Post-Pandemic Period: A Portuguese Cross-Sectional Study
Publication . Antão, Celeste; Rodrigues, Urbano; Fernandes, António; Ribeiro, Maria Isabel
Job satisfaction (JS) among nurses has been the subject of study by academia and organizations worldwide. Its potential impact on the quality and safety of patient care is described in several studies. Therefore, the aim of this research was to determine nurses’ level of JS in a hospital unit in Northeast Portugal. This cross-sectional and analytical study was conducted. A simple random sample of 149 nurses was surveyed through a questionnaire that included sociodemographic variables and the JS Scale by Siqueira (2008). The data were analyzed using software suitable for Social and Health Sciences. The internal consistency of the JS scale dimensions, assessed using Cronbach's alpha, was good to very good (α > 0.8). The JS was low (𝑥̄ = 3.6; SD = 0.987), primarily due to dissatisfaction with salaries (𝑥̄ = 2.1; SD = 1.182) and career progression (𝑥̄ = 2.4; SD = 1.267). Satisfaction with colleagues (𝑥̄ = 4.6; SD = 1.296), work’s nature (𝑥̄ = 4.4; SD = 1.224), and management (𝑥̄ = 4.3; SD = 1.518) contributed positively to JS. Furthermore, satisfaction with colleagues varied by age, service length, and contract type (p < 0.05). Additionally, gender was a significant factor in salary satisfaction (p<0.05). Finally, JS differed in service length (p < 0.05). Most nurses expressed dissatisfaction, highlighting the need to implement strategies to improve JS, particularly through more attractive salaries and opportunities for career advancement, as well as through gradual development of skills, knowledge, and responsibility.
Understanding Differences in Swimming Velocity and Propulsive Force in the Butterfly Stroke: A Comparison Between Male and Female Butterfly Swimmers Through Discrete and Continuous Variables
Publication . Pinto, Mafalda; Neiva, Henrique P.; Sampaio, Tatiana; Oliveira, João P.; Morais, J.E.; Marinho, D.A.; Barbosa, Tiago M.
The aim of this study was to verify differences in swimming velocity and propulsive force (PF) between male and female swimmers in the butterfly stroke based on discrete variables and Statistical Parametric Mapping (SPM—continuous variables). The sample comprised 20 young national-level swimmers (10 boys with 17.9 ± 1.2 years and 10 girls with 15.5 ± 1.4 years). Swimming velocity, intracyclic variation of swimming velocity, stroke frequency, stroke length, stroke index, and PF were measured as discrete variables. Swimming velocity and PF were also measured as continuous variables with SPM. As a discrete variable, swimming velocity presented significant differences between sexes with very large effect sizes (p < 0.001, d = 2.46). The average PF also presented significant differences between sexes with very large effect sizes (p < 0.001, d = 2.01). Male swimmers were faster and generated greater PF than female swimmers. As for SPM, velocity presented significant differences between sexes (t = 3.355, p < 0.001) between ∼31 and ∼56% of the stroke cycle. This corresponds mainly to the end of the pull and most of the push phase. PF followed the same trend, with differences in the same phase of the time series. SPM allowed for identification where, within the stroke cycle, differences between sexes occurred in velocity and PF. Being in the same phase of the time series highlights the existing velocity–PF relationship. SPM can allow researchers and coaches to pinpoint the exact moments within the stroke cycle where differences between swimmers may occur
O papel das redes sociais na aprendizagem dos alunos do ensino médio e superior em Moçambique
Publication . Rocha, Atumane Paulino; Posse, Sónia Deolinda Banguira; Gonçalves, Bruno F.
As redes sociais têm um impacto significativo na disseminação de informações e conhecimentos de maneira dinâmica, especialmente no contexto educacional. Nos últimos anos assiste-se a um rápido crescimento no uso das redes sociais em todos os sectores da sociedade. No contexto moçambicano, esse fenómeno intensificou-se ainda mais durante o pico da pandemia de COVID-19, quando as escolas foram forçadas a encontrar maneiras de continuar a ensinar remotamente. Este artigo busca compreender o papel das redes sociais no ensino e aprendizagem, considerando aspectos como colaboração, a partilha de conteúdos, os mecanismos de recomendação e a interação social. Em termos metodológicos, ao objetivar captar percepções sobre o papel das redes sociais, a pesquisa segue abordagem qualitativa, e a técnica de recolha de dados será suportada numa revisão bibliográfica e entrevista semiestruturada. Ao longo da discussão dos capítulos, foi possível verificar que os diversos autores que abordaram a temática, bem como os entrevistados, reforçam a percepção de que as redes sociais desempenham um papel duplo na vida educacional, combinando entretenimento e oportunidades de aprendizagem. No entanto, salientam-se a preocupação com a qualidade e a confiabilidade das informações partilhadas, a garantia da segurança e a privacidade dos utilizadores. A pesquisa apurou ainda que o WhatsApp é a rede social mais usada para partilhar informações e conteúdos relevantes, o Google Classroom é a ferramenta utilizada para a gestão e partilha de materiais e tarefas escolares e o Facebook é utilizado, mas não muito no contexto educacional.
