Inter rater disagreements in applying the montreal classification for Crohn's d...
Ukashi, Offir; Amiot, Aurelien; Laharie, David; Menchén, Luis; Gutiérrez, Ana; Fernandes, Samuel; Pessarelli, Tommaso; Correia, FábioBackground: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification. Methods: An online survey ...
The Development of a Novel Nitrate Portable Measurement System Based on a UV Pa...
Fernandes, Samuel; Tlemçani, Mouhaydine; Bortoli, Daniele; Feliciano, Manuel; Lopes, Maria ElminaNitrates can cause severe ecological imbalances in aquatic ecosystems, with considerable consequences for human health. Therefore, monitoring this inorganic form of nitrogen is essential for any water quality management structure. This research was conducted to develop a novel Nitrate Portable Measurement System (NPMS) to monitor nitrate concentrations in water samples. NPMS is a reagent-free ultraviolet system...
A Portable Measurement Device Based on Phenanthroline Complex for Iron Determin...
Fernandes, Samuel; Tlemçani, Mouhaydine; Bortoli, Daniele; Feliciano, Manuel; Lopes, Maria Elmina: In this work, a newly developed self-contained, portable, and compact iron measurement system (IMS) based on spectroscopy absorption for determination of Fe2+ in water is presented. One of the main goals of the IMS is to operate the device in the field as opposed to instruments commonly used exclusively in the laboratory. In addition, the system has been tuned to quantify iron concentrations in accordance wit...
Rates of adverse events in patients with Ulcerative Colitis undergoing colectom...
Dragoni, Gabriele; Innocenti, Tommaso; Amiot, Aurelién; Castiglione, Fabiana; Melotti, Laura; Festa, Stefano; Savarino, Edoardo Vincenzo; Truyens, MarieINTRODUCTION: Patients with ulcerative colitis (UC) receiving immunosuppressive drugs are at substantial risk of colectomy. We aimed to assess the risk of postoperative complications of tofacitinib exposure before colectomy in comparison with biologics. METHODS: A multicenter, retrospective, observational study was conducted in patients with UC who underwent total colectomy for medically refractory disease, exp...

Development of portable water quality assessment instruments using embedded sys...
Fernandes, SamuelCurrently, most water parameters determinations are carried out into highly specialised laboratories, using the state-of-art bench top instruments, designed to provide precision and accuracy for a large variety of substances in samples that present very extreme complex matrices. This classical approach presents significant challenges in terms of sampling, analysis and costs. Nitrates are in important source of ...
Transmural remission improves clinical outcomes up to 5 years in Crohn's disease
Fernandes, Samuel; Serrazina, Juliana; Botto, Inês Ayala; Leal, Tiago; Guimarães, Andreia; Garcia, Joana Lemos; Rosa, Isadora; Prata, RitaIntroduction: Evidence supporting transmural remission (TR) as a long-term treatment target in Crohn's disease (CD) is still unavailable. Less stringent but more reachable targets such as isolated endoscopic (IER) or radiologic remission (IRR) may also be acceptable options in the long-term. Methods: Multicenter retrospective study including 404 CD patients evaluated by magnetic resonance enterography and colon...
Sexual quality of life in inflammatory bowel disease: A multicenter, national-l...
Roseira, Joana; Magro, Fernando; Fernandes, Samuel; Simoes, Carolina; Portela, Francisco; Vieira, Ana Isabel; Patita, Marta; Leal, Carina; Lago, PaulaBackground: The impact of inflammatory bowel disease (IBD) on sexual health is a leading concern among patients. Most studies focus on sexual dysfunction rather than patient-perceived sexual quality of life (SQoL). We aimed to assess SQoL in IBD patients compared with healthy controls. Methods: This is a multicenter, cross-sectional study of IBD patients (n = 575 with Crohn's disease and n = 294 with ulcerative...
Monitorização e controlo de qualidade do ar interior em gabinetes de edifícios ...
Fernandes, Samuel; Igrejas, Getúlio; Feliciano, ManuelUm sistema de monitorização e controlo de Qualidade do Ar Interior (QAI) foi construído com o objetivo de testar a sua viabilidade como solução na melhoria de QAI em gabinetes de edifícios escolares. O sistema tem a capacidade de monitorizar as concentrações de CO2, CO, humidade relativa e temperatura e integra um mecanismo de ventilação dinâmico capaz de regular os níveis de QAI em função dos níveis de CO e/ou...
Young Users and the Swipe Logic in Smartphones
Fernandes, Samuel; Rodrigues, Rui; Oliveira, LídiaIn a society of quick technological development, coupled with the growing use of smartphones, new habits of interaction and consumption of contents arise, namely, through gestures based on touch. One of these new habits of interaction is the swipe - quick movement done with the thumb. This gesture allows users to make decisions quickly, spontaneously and decisively, which may not only refer to the swipe logic a...
