Hesitancy and Refusal of the COVID-19 Vaccine Among Healthcare Professionals: A...
Teófilo, Vanessa; Amaro, Joana; Matos, Pedro; Pinho, Paulo; Moreira, Salomé; Ribeiro, Rui; Miller, Mariana; Pinelas, Sofia; Silva, FilipaIntroduction: Vaccine hesitancy is recognized by the World Health Organization as a major global health threat. In the context of the COVID-19 pandemic, this issue has taken on unique dimensions. Healthcare professionals are considered one of the most reliable sources of information regarding vaccination. Their stance on immunization is a determining factor in their likelihood to recommend it to others, with po...
Synergistic effects in hybrid buckypapers of graphene nanoplatelets and carbon ...
Silva, Thais da; Silva, Thiély da; Corrêa, Rieyssa; Ribeiro, Rui; Morgado, Guilherme; Montagna, Larissa; Uribe, Braian Esneider BuitragoHybrid buckypapers (BPs) composed of graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs) hold great potential for applications in flexible electronics, electromagnetic shielding, and energy storage. In this study, hybrid BPs were fabricated and characterized to evaluate their structural, thermal, and electrical properties. Hybrid BPs with varying GNP/CNT mass ratios (0/100, 25/75, 50/50, 75/25, 85/15, 90/...
High lignin content polymer filaments as carbon fibre precursors
Ribeiro, Rui; Guerreiro, Miguel; Reis, Renato; Martins, Joana T.; Vieira, J.M.P.; Silva, Mariana Martins da; Covas, J. A.; Paiva, Maria C.The growing environmental awareness, the search for alternatives to fossil resources, and the goal of achieving a circular economy have all contributed to the increasing valorization of biowaste to produce bio-based polymers and other high-value products. Among the various biowaste materials, lignin has gained significant attention due to its high aromatic carbon content, low cost, and abundance. Lignin is pred...
OAGB bowel function in patients with up to 5 years follow-up: updated outcomes
Rossoni, Carina; Bragança, Rossela; Santos, Zélia; Viveiros, Octávio; Ribeiro, RuiObjective: One-anastomosis gastric bypass (OAGB) is considered an effective technique in weight reduction and remission of comorbidities. However, in common with many bariatric and metabolic/bariatric procedures, gastrointestinal side effects are frequently reported, but clinical experience varies. The objective of this study was to analyze the bowel function of patients who undergo OAGB looking at 5-year posto...
Beyond batch experiments: unveiling the potential of bimetallic carbon xerogels...
Silva, Adriano S.; Roman, Fernanda; Ribeiro, Rui; Garcia, Juan; Gomes, HelderSingle- and bimetallic carbon xerogels were prepared by incorporating iron and iron-cobalt precursors during their synthesis, respectively, and tested in the catalytic wet peroxide oxidation (CWPO) of ibuprofen spiked into a simulated matrix in batch mode. The bimetallic catalyst outperformed single and non-metallic catalyst by 25 and 85% after 360 min of reaction, at mild temperature (30 °C). The best-performi...
Spontaneous Pneumomediastinum: A Rare Cause of Chest Pain
Barroso, Daniela; Rocha, Diana I.; Abelha Pereira, Filipa; Ribeiro, Rui; Pimenta Fernandes, João; Pais Monteiro, Ana; Silva, Isabel FonsecaSpontaneous pneumomediastinum is a rare medical condition characterized by the presence of free air in the mediastinum, not preceded by trauma, surgery, or another medical procedure. It predominantly affects young adult males and usually has a benign course, and in most cases, it is not possible to identify the precipitating factor. There are some conditions that predispose to its occurrence, namely those that ...
A data-driven intelligent decision support system that combines predictive and ...
Ribeiro, Rui; Pilastri, Andre; Moura, Carla; Morgado, Jose; Cortez, PauloIn this paper, we propose an Intelligent Decision Support System (IDSS) for the design of new textile fabrics. The IDSS uses predictive analytics to estimate fabric properties (e.g., elasticity) and composition values (% cotton) and then prescriptive techniques to optimize the fabric design inputs that feed the predictive models (e.g., types of yarns used). Using thousands of data records from a Portuguese text...
Gastrointestinal reported outcomes following one anastomosis gastric bypass bas...
Sherf-Dagan, Shiri; Biton, Reut; Ribeiro, Rui; Kessler, Yafit; Ben-Porat, Tair; Raziel, Asnat; Rossoni, Carina; Kais, Hasan; Bragança, RosselaObjectives: To describe gastrointestinal-related side-effects reported following One Anastomosis Gastric Bypass (OAGB). Methods: A multicenter study among OAGB patients across Israel (n=277) and Portugal (n=111) who were recruited to the study based on time elapsed since surgery was performed. An online survey with information on demographics, anthropometrics, medical conditions, and gastrointestinal outcomes w...

Sherf-Dagan, Shiri; Biton, Reut; Ribeiro, Rui; Kessler, Yafit; Raziel, Asnat; Rossoni, Carina; Kais, Hasan; Bragança, Rossela; Santos, ZéliaThis study aimed to describe nutritional and lifestyle parameters following one-anastomosis gastric bypass (OAGB). A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) was performed. Patients were approached according to the time elapsed since surgery. An online survey with information regarding demographics, anthropometrics, and nutritional and lifestyle aspects was administer...
