- Bone mineral density and body composition among individuals who practice sports with mechanical impact and sedentary activitiesPublication . Pinheiro, João; Ribeiro, Luís Pedro; Coelho-e-Silva, ManuelThe purpose of this study was to evaluate indicators of bone health associated with sports practice in male adolescents using dual-energy X-ray absorptiometry (DXA) to measure bone mineral content (BMC), density (BMD), and body composition (BC) for the whole body (WB) and specific regions. This cross-sectional study involved 65 individuals (18–35 years). Athletes had higher BMD for WB (1.064 ± 0.121 g/m−2) than sedentary individuals (0.753 ± 0.129 g/cm−2). Differences were also observed within specific regions such as the trunk, upper and lower limbs. Individuals who practice regular sports present improved bone health indicators compared to their sedentary peers.
- Commentary on: nurses’ perceptions of artificial intelligence (AI) integration into practice: an integrative reviewPublication . Xavier, Tânia; Oliveira, ClaudiaWe are writing this letter to congratulate you on the paper ‘Nurses’ perceptions of artificial intelligence (AI) integration into practice: An integrative review’ by Lora and Foran, recently published in your journal. In this paper the authors synthesise remarkable, valuable and challenging aspects of the new era of artificial intelligence (AI) in the clinical practice of nursing. AI has been introduced into the most diverse areas of knowledge, opening a vast range of possibilities. This integrative review makes a timely and relevant contribution to the growing body of literature on the intersection between nursing and AI. The authors show that the practice of nursing, especially in the perioperative environment, is no exception.
- Densidade dos Côndilos Mandibulares medidos por Tomografia Computorizada - estimativa da Idade à MortePublication . Pinheiro, João Pedro Alexandre; Godinho, RicardoA estimativa da idade à morte (IM) representa um foco central da análise antropológica e arqueológica dos remanescentes esqueléticos humanos. Vários fatores confundidores e especificidades atuam sob o ambiente em que estes foram depositados. O presente trabalho testa a possibilidade de estimar a IM de espécimes arqueológicos usando uma amostra populacional contemporânea de dados biométricos conhecidos como referência, com recurso a um equipamento de tomografia computadorizada para medição de indicadores ósseos. A amostra conhecida tem correlação estatisticamente significativa entre o aumento da idade e a diminuição da densidade mineral óssea (p<0.05), para a densidade dos côndilos mandibulares no plano axial e coronal, bem como a densidade cortical na base e tuberosidade (sig. 0.002 e 0.009 para p<0.05). No entanto, a amostra apresenta também grande variabilidade de densidade para as várias faixas etárias. Quando comparada, a amostra arqueológica, interseta vários valores de densidade óssea para indivíduos entre os 25 e os 75 anos de idade. O osso cortical apresenta os valores de densidade óssea mais próximos da amostra de referência e poderá ser uma via de investigação futura noutros locais do esqueleto. Apesar de existir correlação entre a densidade óssea e a idade para regiões específicas dos côndilos mandibulares não foi possível predizer com fiabilidade a IM das amostras a arqueológicas.
- Does a 12-week yoga program influence the decision-making capacity of military aviation pilots?Publication . Santos, Sara; Fernandes, Orlando; Cabo, Carolina A.; Parraca, José A.; Melo, FilipeDoes a 12-week yoga program influence the decision-making capacity of military aviation pilots? Rationale and aims: This study investigates whether the incorporation of yoga practice into the training regimen of Portuguese Airforce Aviation Pilots can enhance their decision-making capacity, in order to promote better occupational health safety. Methods: A randomized controlled trial with Portuguese Airforce pilots had the Control Group (n = 8), follow standard military aviation training, and the Intervention Group (n = 10), receive additional yoga training twice a week for 12 weeks. Cognitive/performance assessments included the Aviation Safety Attitude Scale (ASAS). The procedures were approved by the Évora University research ethics committee (approval number: 21050), and participants gave written informed consent per the Helsinki declaration. The study was registered on April 19, 2023, on ClinicalTrials.gov (identifier NCT05821270). Analysis: Data analysis used Jamovi (version 2.3.16). Normality was assessed with the Shapiro-Wilk test, non-parametric data analysis used Wilcoxon rank test and Rank Biserial Correlation for effect sizes. Statistical significance was generally determined with a threshold of 0.05. Findings: Results showed significant differences in ASAS: it indicated significant increases in Self-Confidence (p = 0.021), Risk Orientation (p = 0.024), and Safety Orientation (p = 0.021) within the yoga group. Conclusions: This research offers a unique contribution: studying the hard-to-access population of military aviation pilots, due to security and workload constraints. Portuguese Airforce pilots, facing high stress and lacking a structured training regimen, will benefit from the findings of this study. Results could influence policymakers to implement mandatory exercise programs, enhancing work safety. These insights are also applicable to Airforce teams in other nations, commercial and civil aviation sectors.
- Editorial: Innovative teaching and learning in health education and promotionPublication . da Costa, Emilia; Ruiz Fernández, María Dolores; Fernández Medina, Isabel María; Jimenez Lasserrotte, Maria del Mar; Ventura-Miranda, Maria IsabelHealth education and health promotion are undergoing profound transformation. Demographic transitions, aging populations, increasing multimorbidity, persistent inequities, and rapid technological change are reshaping how learners understand and navigate health. In this evolving context, traditional knowledge-transmission models are no longer sufficient to prepare future professionals for complex, multicultural and digitally mediated environments. Innovation in teaching and learning has therefore become essential, not only to improve learning outcomes, but to strengthen ethical reasoning, equity, and learner autonomy. This global shift echoes recent OECD (1) analyses highlighting how digitalisation, demographic aging and widening social disparities are redefining the competencies required of tomorrow’s health workforce and calling for educational approaches attuned to complexity and uncertainty. It is also consistent with the World Health Organization’s call for transformative health workforce education, which stresses that conventional training models can no longer meet the demands posed by demographic change, chronic disease burdens, technological acceleration and growing inequities.
- Food insecurity in higher education studentsPublication . Paula, Aline de; Carneiro, Beatriz; Mendes, Inês; Pacheco, Mariana; Gonçalves, Marta; Pinto, Ezequiel; Palma Mateus, MariaFood insecurity (FI) indicates a situation in which there is no regular access to food in satisfactory quantity and quality. To characterize FI in students from Portuguese higher education institutions, a study was conducted in a non-random sample of students, with an online questionnaire consisting of sociodemographic questions and the Portuguese version of the IF scale. There were 200 valid questionnaires and 27.5% of the participants were classified as having some degree of FI. Participants with FI reported fewer visits to the family’s home (p = 0.024) and less financial resources (p < 0.001). The results indicate that interventions are needed in this area.
- Gamification on mathematics engagement and motivation in secondary school and higher education: a systematic review and meta-analysisPublication . Ratinho, Elias; Figueiredo, Mauro; Estêvão, Maria Dulce da Mota Antunes de Oliveira ; Faísca, Luís; Martins, CátiaThis systematic review and meta-analysis examined the effects of gamification on students’ motivation and engagement in mathematics at the secondary and higher education levels. A literature search (April 2025) followed by an updated search (November 2025) across ten databases identified 45 studies for qualitative synthesis and 11 for meta-analysis. The review followed PRISMA 2020 guidelines with a pre-registered protocol, and study quality was appraised with the Mixed Methods Appraisal Tool. Meta-analytic results using a three-level Correlated and Hierarchical Effects model with robust variance estimation showed a significant small-to-moderate positive effect on motivation (g = .383, 95% CI [.11, .66], p = .0218). Motivation was assessed more consistently than engagement that could not be included in the meta-analysis due to the lack of validated measures. The systematic review indicates that gamification supports motivation and engagement, with only four studies reporting negative effects. Most interventions used digital platforms (e.g., Kahoot!; Classcraft) and common game elements such as points, leaderboards and instant feedback. Overall, gamification appears promising for enhancing motivation and engagement in mathematics when designs are aligned with students’ needs, balancing competition with mastery and cooperation. Therefore, educators should limit excessive competition and prioritize personal progress and cooperative tasks that foster social interaction. Future studies should employ validated measures, larger samples, and examine both motivation and engagement to strengthen the evidence base and guide effective implementation in education.
- High vs low protein intake in chronic critical illness: a systematic review and meta-analysisPublication . Castro, Sílvia; Tome, Ana Maria; Granja, C.; Macedo, A.; Binnie, AlexandraBackground & aims: Patients with persistent organ dysfunction after the first week of intensive care unit (ICU) admission are considered to have chronic critical illness (CCI). Acquired muscle weakness is a common feature of CCI that is accompanied by loss of muscle mass and electromyographic features of myopathy. Optimizing protein intake may help prevent acquired muscle weakness and/or promote muscle recovery, however, the optimal level of protein intake in CCI is uncertain and there is a lack of consensus in published nutritional guidelines. This systematic review focuses on the impact of high versus low protein intake as part of a nutritional strategy for patients with CCI. Methods: The terms “protein intake” and “critically ill” were systematically searched in PUBMED, CENTRAL (Cochrane Central Register of Controlled Trials), and WEB OF SCIENCE on 06/01/2023. We included studies that (1) enrolled critically ill adults (aged 18 years or over) who were in the ICU for more than 7 days and that compared (2) protein intake above and below 1.3 gr/kg administered by any route (enteral and/or parenteral), (3) had an intervention period that occurred primarily after the first 7 days of critical illness and (4) reported clinical outcomes including length of ICU and hospital stay, duration of invasive mechanical ventilation (IMV), mortality, ICU acquired infections, muscle mass and physical function. Studies pertaining to elective surgery, those with intervention periods shorter than 7 days or occurring primarily within the first 7 days of critical illness, those measuring only laboratory parameters as outcomes, and safety and feasibility studies were excluded. Results: Four studies were included (N ¼ 1730) in the meta-analysis and systematic review. Higher (>1.3 g/kg/d) versus lower protein intake was associated with a decrease in early mortality (defined as ICU or 28-day mortality) hazard ratio (HR) 0.42 (95 % confidence interval (CI): 0.26e0.70, P < 0.001), but had no impact on late mortality (defined as the latest mortality timepoint in each study): HR 0.93 (95 % CI 0.76e1.15, P ¼ 0.51). There was no significant difference between intervention and control groups with respect to duration of IMV, duration of ICU or hospital stay, muscle mass, or the incidence of ICUacquired infections. One study reported improvements in physical function at 3 and 6 months in the intervention group. Conclusion: After the first week of critical illness, increasing protein intake to >1.3 g/kg/d may improve early mortality but not late mortality or other clinical outcomes. The small number of relevant studies and the heterogeneity of outcomes assessed, weaken these conclusions. Further studies are warranted to discern whether higher protein intake is beneficial in chronic critical illness. PROSPERO registration number: CRD42023403554; PROSPERO registration name: “The effect of higher than 1,3 g/kg of protein versus lower intake in chronic critically ill patients”
- The immune tumor microenvironment in gliomas: may CITED2 play a role?Publication . Teotónio Fernandes, Mónica AlexandraGliomas are the most common brain cancers, resulting from transformed glial cells. CITED2 is a co-transcriptional regulator previously implicated in several types of cancer, affecting both cellintrinsic processes and the microenvironment. Because in breast cancer it was shown to contribute to the recruitment of macrophages and their polarization to an immunosuppressive phenotype, a potential similar role was explored in gliomas. By analyzing publicly available databases using a set of bioinformatics tools, it was found that CITED2 is overexpressed in higher-grade gliomas and contributes to an adverse prognosis. In addition, CITED2 expression correlates with macrophage infiltration and a M2 phenotype.
- Impact of bariatric and metabolic surgery on sarcopenia-related parameters according to the EWGSOP2 consensus criteria in persons living with obesityPublication . Cardoso, Paulo Alexandre e Castro; Santos, Tânia V.; Ramon-Krauel, Marta; Pais, Sandra; De Sousa-Coelho, Ana LuísaAlthough bariatric and metabolic surgery (BS) has proved effective in the treatment of obesity based on the reduction in fat mass and the remission of comorbidities, there is also loss of lean mass after BS which could compromise muscle functionality. According to the European Working Group on Sarcopenia in Older People (EWGSOP), sarcopenia is a disease associated with loss of muscle mass, strength, and function. Through a comprehensive review of the literature, we identified a range of studies focusing on evaluating sarcopenia-related parameters according to the EWGSOP2 consensus criteria, before and after BS. Although most studies reported reductions in skeletal muscle mass and absolute muscle strength after surgery, improvements in muscle functionality were generally achieved, independent of the type of BS.
