Sentinel Lymph‑Node Biopsy or Targeted Axillary Dissection in Node‑Positive B...
Sousa, Nuno; Pinto, Catarina; Peleteiro, Barbara; Fougo, JoséIntroduction: Targeted axillary dissection (TAD) was designed for nodal staging in cN+ breast cancer (BC) patients submitted to neoadjuvant therapy (NAT). A recent study questioned the need to mark suspicious nodes pre-NAT. Methods: cT1-4 N1-2 BC patients scheduled for NAT were selected for retrospective appraisal. Patients were divided according with SLNB/TAD and ycN0/ycN+ status. Detection rate (DR), concorda...
CHATBOTS NA CIÊNCIA DA INFORMAÇÃO
Sousa, Nuno; Rockembach, MoisésA presença da Inteligência Artificial (IA) tem vindo a crescer em vários setores, e arquivos e bibliotecas não são exceção. Entre as soluções tecnológicas mais adotadas recentemente, os chatbots têm assumido um papel relevante, ajudando na comunicação com os utilizadores e facilitando o acesso a recursos informacionais. Estes sistemas permitem automatizar tarefas repetitivas, tornando os serviços mais ágeis e a...
Models for light propagation in the head: trends and implementation of Finite E...
Fernandes, Filipa Gracinda Silva; Silva, Filipe Samuel; Sousa, Nuno; Carvalho, Óscar Samuel Novais; Catarino, Susana OliveiraThe simulation of light propagation in the head tissues has become of interest due to its applicability in transcranial photobiomodulation (tPBM). In silico studies appear as an effective way to research tPBM dosimetry and understand the light reach in the head tissues, as well as potential issues regarding tissue heating. Nonetheless, these computer models are still very simple and come with several limitation...
Experimental and in silico models for studying light propagation in the head
Fernandes, Filipa Gracinda Silva; Silva, Filipe Samuel; Sousa, Nuno; Carvalho, Óscar Samuel Novais; Catarino, Susana OliveiraTranscranial photobiomodulation (tPBM) is an alternative therapy to conventional approaches, with clinical studies that show promising results for the treatment of several neurological pathologies, such as stroke and dementia related conditions. Despite its potential, the optimal light parameters and dosimetry for effective tPBM therapy remain uncertain, with most literature on this topic highlighting the need ...
Development and Validation of the “Physical Functional Impact Index on Chronic ...
Antunes, Filipe; Sousa, Nuno; Teixeira, PedroIntroduction: The development and validation of reliable and valid instruments to assess chronic pain and its impact on daily functioning are crucial in both clinical and research settings. The aim of this study was to develop and validate the scale ‘Physical Function Impact Index on Chronic Pain’ – PFIICP, a novel 12-item questionnaire designed to evaluate the physical functional impact on chronic pain.Methods...
Determinants of fare evasion in urban bus lines: case study of a large database...
Freiria, Susana; Sousa, NunoThis article presents a large case study of fare evasion on bus lines in the city of Lisbon, Portugal, a common problem in dense urban areas. Focus is put on geographic factors, and an analysis is carried out using a generalized spatial two-step least-squares regression (GS2SLS). The large database, spanning one year of fare evasion reports, made it possible to segregate the analysis according to type of day (w...
Walking to public transport: rethinking catchment areas considering topography ...
Pais, Filipe; Sousa, Nuno; Monteiro, João Pedro Medina; Rodrigues, João Coutinho; Jesus, Eduardo NatividadeService, or catchment areas of public transport stops are traditionally assessed using Euclidean or network distances, often neglecting other relevant factors such as topography. This study proposes a refined approach that integrates network-based accessibility with terrain variations and the effect they have on walking time and on the physical effort required for pedestrian movement. Using geographic informati...
Face-to-face interactions estimated using mobile phone data to support contact ...
Cumbane, Silvino; Gidófalvi, Gyözö; Cossa, Osvaldo; Madivadua Júnior, Afonso; Branco, Frederico; Sousa, NunoUnderstanding people’s face-to-face interactions is crucial for effective infectious disease management. Traditional contact tracing, often relying on interviews or smartphone applications, faces limitations such as incomplete recall, low adoption rates, and privacy concerns. This study proposes utilizing anonymized Call Detail Records (CDRs) as a substitute for in-person meetings. We assume that when two indiv...
Hybrid learning in the age of Generative AI
Bidarra, José; Rocio, Vitor; Sousa, NunoUniversities must have the aspiration to become key institutions in this new era of Artificial Intelligence (AI), as generators of knowledge, science and research, promoting the democratisation of knowledge. Also, management in Higher Education must increase faculty readiness for e-learning changes, particularly since e-learning remains essential to maintaining curriculum delivery during emergencies and crises....
Do people adapt to where they live?: a comparative analysis of perceived physic...
Medina Monteiro, João Pedro; Sousa, Nuno; Jesus, Eduardo Natividade; Rodrigues, João Coutinho; Oliveira, Leise Kelli; Santos, Patrícia da SilvaThis article examines the question of whether people perceive their own urban environment more favourably than people from other urban environments, i.e., whether residents, in a sense, adapt to where they live. To analyse this question, a quantitative statistical model that uses geometric and land use elements was applied to a case study of Belo Horizonte, Brazil, to estimate the perception of physical pleasan...
