- 2ARTs: A Platform for Exercise Prescriptions in Cardiac Recovery PatientsPublication . Pereira, Andreia; Martinho, Ricardo; Pinto, Rui; Rijo, Rui; Grilo, CarlosDue to limited access, increasing costs and an ageing population, the global healthcare system faces significant coverage problems that call for innovative approaches. Health professionals are actively seeking alternative methods to provide care to an increasingly needy population, without increasing human effort and associated costs. eHealth platforms, which use technology to provide patient care, are emerging as transformative solutions for addressing these problems. This study is centered on the demand for a Decision Support System (DSS) in cardiology to enable doctors to prescribe individualized care inside Cardiac Rehabilitation Programmes (CRPs). The 2ARTs project’s main objective is to include a cardiac rehabilitation platform with a DSS within the hospital infrastructure. This DSS uses models to classify patients into different groups, delivering crucial information to assist with decisions regarding treatment. Regarding the DSS, Principal Component Analysis (PCA) emerged as a standout technique for dimensionality reduction, due to its interoperability with clustering algorithms and superior evaluation metrics. The most appropriate clustering technique was determined to be the K-means algorithm, which was supported by the experts analysis. In accordance with the goals of the 2ARTs project, this integration of PCA and K-means provides meaningful insights that improve reasoned decision-making.
- Abieta-7,13-Diene in Nematode-Infected Pinewood Pinus pinaster Branch Extracts: Isolation and the Elucidation and Characterization of Its StructurePublication . Gaspar, Marisa C.; Cruz, Pedro F.; Brito, Rui M. M.; Sousa, Hermínio C. de; Braga, Mara E. M.The oleoresin and volatile fraction produced by conifers, such as Pinus pinaster, play a crucial role in plant defence, acting as precursors to resin acids and adapting in response to environmental stress or pathogen attacks. Abietadiene (abieta-7,13-diene), the biosynthetic precursor to abietic acid, has been identified as the most abundant compound in extracts from pinewood nematode (PWN)-infected P. pinaster trees. As abietadiene is not commercially available, this study aimed to achieve, for the first time, its isolation, structure elucidation, and detailed characterization from readily available forestry residues. Abietadiene was successfully isolated using thin-layer chromatography (TLC), and its purity and identity were evaluated using multiple analytical techniques: gas chromatography (GC), liquid chromatography (LC), nuclear magnetic resonance (NMR), and Fourier-transform infrared spectroscopy (FTIR). GC analysis indicated a purity of over 70% for the isolated compound, while LC provided the higher purity value of 98%. The identity of abietadiene was unequivocally confirmed through LC, FTIR, and NMR analysis. This work represents the first isolation and comprehensive characterization of abietadiene from a natural source, making detailed chemical data on this compound available to the scientific community. These findings may be used for future studies on the biological interactions and ecological roles of abietadiene, particularly in the context of plant defence and pathogen resistance.

- Acute effects of dynamic stretching on knee joint position sense and dynamic balance in recreational runners: A randomized controlled trialPublication . Simões, Edgar; Tavares, Nuno; Saraiva, MarinaObjectives: Proprioception and dynamic balance are crucial elements of neuromuscular control during running, supporting movement precision and postural adjustments. Dynamic stretching is commonly used in warm-ups to enhance muscle activation and sensorimotor readiness, but its acute effects on proprioception and balance remain unclear. Design: Randomized controlled trial. Participants: Sixty-two healthy recreational runners (25–45 years; ≥20 km/week), randomly assigned to a Dynamic Stretching group (n = 31) or a control group performing light walking (n = 31). Main outcome measures: Joint position sense was assessed through active joint repositioning using 2D video analysis, with Absolute Angular Error, Relative Angular Error, and Variable Angular Error as outcomes. Balance was evaluated using the Y-Balance Test, including anterior, posteromedial, and posterolateral reach directions, as well as a composite score. Results: The Dynamic Stretching group showed significant reductions in Absolute Angular Error (p < 0.05) and Variable Angular Error (p < 0.001), with a between-group difference in Relative Angular Error (p = 0.043). Both groups improved Y-Balance Test scores, but the Dynamic stretching group achieved significantly greater gains in posteromedial reach and Composite Score (p < 0.001). Conclusions: Dynamic stretching acutely improves proprioceptive accuracy and dynamic balance in recreational runners, supporting its inclusion in warm-up routines.
- Adolescent gender identity and sexual orientation: a school-based correlational studyPublication . Cordeiro, Ana Catarina Lobo Maurício; Da Mota, Ana João Dinis; Barros, Teresa Madalena Kraus Brincheiro Hüttel; Ramalho, Sónia; Gordo, Clementina Maria Gomes de Oliveira; Dixe, Maria dos Anjos Coelho Rodrigues; Moleiro, PascoalAdolescents are increasingly encouraged to freely express their sexuality. The purpose of this study was to compare non-cisgender adolescents with cisgender/heterosexual adolescents and those who have an undefined gender identity and/or sexual orientation, on their future prospects, emotional state, sexuality, risk behaviors, and their perception of health care and its accessibility. Adolescents who identify as non-cisgender/heterosexual seem to have higher future aspirations, however, they have a more unstable emotional state, higher risky behaviors, and fear being prejudiced by health care professionals. The undefined group appears to be undefined about their sexuality and future aspirations, while reporting less risky behaviors.

- An in-depth introduction to arts-based spiritual healthcare: Creatively seeking and expressing purpose and meaningPublication . Laranjeira, Carlos; Querido, AnaArt therapy entails a therapeutic relationship that allows the expression and exploration of mental and spiritual needs through art (Bell, 2011). It integrates artistic creation, making use of different artistic mediators (Martins, 2013). Through various forms of artistic expression, a person communicates and explores their feelings and intimacy (Lev, 2020). Creative development allows the individual to break forms of resistance, recognize their own capabilities, and feel greater self-esteem and wellbeing (Hu et al., 2021; Ryff, 2021). Exercising creativity enables a differentiated view of oneself and favors the encounter of alternative points of view regarding psychological and spiritual issues (Alvarenga et al., 2018). The aim is personal growth and contact with our sensitive world and emotional development. In the art-therapeutic process, the artistic experience through creation enriches the imaginary and contributes to self-knowledge, driving the elaboration of internal contents and personal transformation (Martins, 2013; Ettun et al., 2014). In the art-therapeutic setting, different artistic mediators facilitate creation, expression and communication, including plastic, musical, dramatic, body, literary, and playful expression. These constitute the technical and material basis for creation. Considering the particular symbolic, expressive, and creative characteristics of different resources and understanding the therapeutic potential of each resource and how they can meet individual needs is fundamental to effective Art Therapy.
