- Non-Newtonian Blood Flow in Portal Vein with Thrombosis: A Study by Computational Fluid DynamicsPublication . Soares, A. A.; Gonzaga, S.; Silva, José Silvestre; Marinho, D.; Silva, A.; Rouboa, AbelWe investigate the effects on non‐Newtonian blood flow model on the wall shear stress (wss), velocity and viscosity distributions. The 3D Navier‐Stokes equations coupled with viscosity models describing the steady flow in Portal Vein have been solved numerically. Three blood viscosity models (Newtonian, Power‐law and Carreau) are used in numerical simulations. The results highlight the influence of these models on the blood flow and show that the viscosity model of blood may have significant impact on the numerical results especially in the region of the thrombosis.
- A textured scale-based approach to melanocytic skin lesions in dermoscopyPublication . Fonseca-Pinto, Rui; Marlene MachadoMelanoma is the most dangerous and lethal form of human skin cancer and the early detection is a fundamental key for its successful management. In recent years the use of automatic classification algorithms in the context of Computer Aided Diagnosis (CAD) systems have been an important tool, by improving quantification metrics and also assisting in the decision regarding lesion management. This paper presents a novel and robust textured-based approach to detect melanomas among melanocytic images obtained by dermoscopy, using Local Binary Pattern Variance (LBPV) histograms after the Bidimensional Empirical Mode Decomposition (BEMD) scale-based decomposition methodology. The results show that it is possible to develop a robust CAD system for the classification of dermoscopy images obtained from different databases and acquired in diverse conditions. After the initial texture-scale based classification a post-processing refinement is proposed using reticular pattern and color achieving to 97.83, 94.44 and 96.00 for Sensitivity, Specificity and Accuracy.
- Saúde das Mulheres em Cabo VerdePublication . Henriques, Carolina; Frade, João; Santos, PauloFalarmos da saúde das mulheres é falarmos da saúde genésica das populações, já que as mulheres são as principais responsáveis pelo cuidado ao outro. Neste estudo procurámos conhecer a saúde e o bemestar das mulheres em cabo verde, seja a nível físico, seja do ponto de vista emocional, através de um estudo quantitativo e descritivo, dirigido a 104 mulheres cabo-verdianas. Os dados mostram-nos que é necessário investirmos na saúde da mulher em Cabo-Verde, já que as experiências de doença nas mulheres tendem a ser ocultadas e vivenciadas em silêncio, parecendo que a mulher carrega o fardo da resignação e sofrimento, já que as mulheres cabo-verdianas tendem a continuar como de costume, guardando esse facto somente para elas.
- Evidence-based practice a relevant piece to update knowledge in mental health nursingPublication . Laranjeira, C.; Querido, A.; Valentim, O.Introduction Web Journal Club as a collaborative learning method, is an effective method to enhance the knowledge base of nursing students, their presentation skills, problem-solving skills and ability to critically appraise literature. Objectives To describe the experience of a online journal club on education of MHN undergraduate students. Methods We implemented a journal club in the online classroom with a total of 24 portuguese undergraduate students enrolled in clinical training of MHN (sixth semester). Over a two-week period, five 2-hour online journal club sessions were conducted in April 2020. During each session, five journal articles were presented synchronously to a live online audience via the Zoom Classroom technology. After all sessions, students were invited by e-mail to complete an anonymous and voluntary online questionnaire via Google Forms. Results All students were all very positive about the journal club sessions and found the opportunity to discuss and reflect on practice issues in depth very helpful. They found the sessions supportive, they helped to bond the group, they learnt a great deal from each others experiences, and they felt that they gained in confidence as a group. Survey results also indicated that few participants experienced technical difficulties during sessions. Conclusions This pedagogical practice enhances gains in the various actors involved: 1) in students, contributing to their learning process and acquisition of competences, articulating research and clinical practice; and 2) lastly, even more indirectly, in people receiving care, since a evidence-based practice ensures safe and quality of nursing care delivery.
- Personal narratives about death and dying: a case study with nursing studentsPublication . Laranjeira, Carlos; Afonso, Catarina; Querido, AnaThis study aimed to qualitatively explore students' meanings of a significant death or dying experience described in the first-person: psycho-emotional and spiritual life reflections. Using a narrative-reflection approach, we performed a multiple case study. Ten nursing students from a 3 rd-year palliative nursing course were selected based on the richness of their experiences. Topics such as the timing of the loss, the manner of death, role changes after the loss, and adjustment patterns were discussed. The role of the narrative is clearly multi faceted – contributing to the development of a student's identity, providing comfort, and helping to make sense of a 'senseless' event.
- Impact of the COVID-19 Pandemic on Adherence to Exercise Prescription: The case of Cardiac Rehabilitation ProgramsPublication . Fonseca-Pinto, Rui; Ferreira, Fábio; Alves, João; Januario, Filipa; Antunes, AlexandreCardiac Rehabilitation Programs (CRPs) are an important tool of secondary prevention and their implementation within health services, despite the uneven geographical distribution, has been receiving attention from decision-makers in recent years. Adherence to the CRPs is one of the great challenges faced by the multidisciplinary team, and there are several strategies to maintain adherence, particularly in CRP-Phase III, which occurs outside the hospital environment. One of the strategies followed is the use of remote performance monitoring and recording of possible alert symptoms. With the pandemic due to COVID-19, these challenges have become even more evident as Phase II programs have been suspended, thus increasing the importance of the home-based CRPs. In this work, the results of a study aiming to understand the impact of the pandemic on adherence to the prescription of exercise and the perception of patients regarding the effects of physical activity on health conditions are shown. The results indicate that the pandemic did not have a major effect on the adherence to home-based exercises, in particular, in patients undergoing programs using a telemonitoring system. Moreover, the perception of the importance of physical activity for health and well-being was reinforced in the context of the pandemic.

- A Conversational Agent for Promoting Physical Activity Among COPD PatientsPublication . Rodrigues, Ricardo; Caceiro, Ruben; Brites, Marcelo; Flora, Sofia; Cruz, Joana; Silva, Fernando; Ribeiro, JoséChronic Obstructive Pulmonary Disease (COPD) is one of the most prevalent diseases in the world, affecting respiratory performance of many people, limiting the airflow and is not fully reversible. It is a clinical syndrome characterized by chronic respiratory symptoms, structural pulmonary abnormalities or impairment of lung function. In order to help people with this disease, we propose an innovative personalized mHealth coaching platform that will address patient preferences and contextual factors – the OnTRACK platform. This platform is composed of a mobile application for patients, a web platform for healthcare professionals – and a conversational agent (or chatbot), named “Hígia”, which acts as an alternative interface between patients and the platform. This conversational agent includes several of the main functionalities already available in OnTRACK’s smartphone app, complementing and extending it. It allows consulting prescription information in a multitude of ways, getting and setting all personal data, inserting physical activity measurements, and obtaining historical data on physical activity and prescriptions, among others. The evaluation of the conversational agent yielded encouraging results, with users reporting being happier, more motivated, dedicated and confident when interacting with the systems using their voice, while allowing the development team to identify topics for improvement.
