Effectiveness of interventions to prevent or treat prolonged grief symptoms amo...
Rosinhas, A; Gomes, A; Silva, R; Ramos, L; Alves, E; Sampaio, FObjective: The objective of this review is to evaluate the effectiveness of interventions to prevent or treat prolonged grief symptoms among families of patients who die in the intensive care unit (ICU). Introduction: Up to 52% of families of patients who die in an ICU may be at risk of experiencing prolonged grief symptoms. This psychological morbidity should be addressed as early as possible through effective...
Relatório científico da Expedição Oceano Azul - Cascais | Mafra | Sintra
Cabral, H; Afonso, CML; Almada, F; Almeida, S; Alonso, H; Andrade, J; Anjos, M; Batista, M; Bentes, L; Carvalho, AC; Celestino, S; Coelho, PD; Coxey, MA zona marítima dos concelhos de Cascais, Mafra e Sintra tem sido pouco estudada, não obstante situar-se frente a grandes centros urbanos e ser alvo de diversos usos e atividades humanas. Algumas das suas características geográficas e dos seus elementos notáveis ao nível dos fundos marinhos acrescem o seu interesse científico e patrimonial. Com o objectivo de ampliar o conhecimento científico sobre a biodiversi...
Clustering-Based Classification of Polygonal Wheels in a Railway Freight Vehicl...
Guedes, A; Silva, R; Ribeiro, D; Magalhaes, J; Jorge, T; Cecília Vale; Meixedo, A; Mosleh, A; Pedro Aires MontenegroPolygonal wheels are one of the most common defects in train wheels, causing a reduction in comfort levels for passengers and a higher degradation of vehicle and track components. With the aim of contributing to the safety and reliability of railway transport, this paper presents the development of an innovative methodology for classifying polygonal wheels based on a wayside system. To achieve that, a numerical...
Early identification of out-of-roundness damage wheels in railway freight vehic...
Jorge, T; Magalhaes, J; Silva, R; Guedes, A; Ribeiro, D; Cecília Vale; Meixedo, A; Mosleh, A; Pedro Aires Montenegro; Cury, AEarly identification of wheel defects can prevent serious damage to railways, considerably lowering maintenance costs for both railway administrations and rolling stock operators. Within this context, an unsupervised methodology based on artificial intelligence techniques is presented, which allows the detection and classification of out-of-roundness damage wheels, such as wheel flats and polygonal wheels, base...
A strategy for out-of-roundness damage wheels identification in railway vehicle...
Magalhaes, J; Jorge, T; Silva, R; Guedes, A; Ribeiro, D; Meixedo, A; Mosleh, A; Cecília Vale; Montenegro, P; Cury, AWayside monitoring is a promising cost-effective alternative to predict damage in the rolling stock. The main goal of this work is to present an unsupervised methodology to identify out-of-roundness (OOR) damage wheels, such as wheel flats and polygonal wheels. This automatic damage identification algorithm is based on the vertical acceleration evaluated on the rails using a virtual wayside monitoring system an...
Challenges in the Preventive Maintenance of Early 20th-Century Reinforced Concr...

Complete blood count parameters as biomarkers of retinopathy of prematurity: a ...
Fevereiro-Martins, M; Santos, AC; Marques-Neves, C; Guimarães, H; Bicho, M; Afonso, C; Ferreira, J; Espírito Santo, R; Teixeira, F; Rosa, RPurpose: To evaluate complete blood count (CBC) parameters in the first week of life as predictive biomarkers for the development of retinopathy of prematurity (ROP). Methods: Multicenter, prospective, observational study of a cohort of preterm infants born with gestational age (GA) < 32 weeks or birth weight < 1500 g in eight Portuguese neonatal intensive care units. All demographic, clinical, and laboratory d...
Clinical, Economic, and Humanistic Impact of Short-Bowel Syndrome/Chronic Intes...
Silva, R; Guerra, P; Rocha, A; Correia, M; Ferreira, R; Fonseca, J; Lima, E; Oliveira, A; Vargas Gomes, M; Ramos, D; Andreozzi, V; Santos, MDIntroduction: This study aimed to assess the clinical, economic, and humanistic impact of short-bowel syndrome/chronic intestinal failure (SBS/CIF) in Portugal. Methods: This is a retrospective multicenter cohort chart review study, with a cross-sectional component for quality-of-life (QoL) evaluation. Inclusion criteria comprised patients with SBS/CIF, aged ≥1 year, with stable parenteral nutrition (PN). Data ...
Characterization and biofouling potential analysis of two cyanobacterial strain...
Romeu, MJ; Morais, J; Luciana Gomes; Silva, R; Vitor Vasconcelos; Filipe MergulhãoThis work assesses the isolation, identification and characterization of two cyanobacterial strains isolated from Morocco and Cape Verde, as well as their biofilm-forming ability at two different surfaces, in a long-term assay under controlled hydrodynamic conditions. Cyanobacteria are new sources of value-added compounds but also ubiquitous and harmful microfoulers on marine biofouling. In this work, the isola...
Lessons from Four Decades of Systemic Amyloidosis with Renal Involvement
Oliveira-Silva, C; Marques, N; Pinho, A; Poínhos, Rui; Bergantim, R; Nunes, AT; Sampaio, S; Rodrigues-Pereira, P; Silva, R; Praça, A; Frazão, JBackground: Apart from ATTR amyloidosis, the epidemiology and outcomes of the most common subtypes of systemic amyloidosis in Portugal remain primarily unknown. Methods: This retrospective cohort study evaluated patients with renal biopsy-proven amyloidosis, diagnosed from January 1978 to December 2019. Follow-up started at kidney disease presentation and ended at death or August 2020. Clinical presentation, su...
