T-cell branched glycosylation as a mediator of colitis-associated colorectal ca...
Leite-Gomes, E; Silva, MC; Dias, AM; Fernandes, Â; Faria, G; Nogueira, R; Santos-Pereira, B; Fernandes-Mendes, H; Azevedo, CM; Raposo, J; Portero, JLBackground and Aims: Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract, established as a risk factor for colorectal cancer (CRC) development. Long-standing inflammation appears to play a central role in colitis-associated colorectal cancer (CAC). However, the molecular mechanism underlying CAC progression is still elusive. Previous evidence showed that levels of b...
Composite Outcomes in Observational Studies of Ulcerative Colitis: a Systematic...
Magro, F; Alves, C; Santiago, M; Ministro, P; Lago, P; Correia, L; Gonçalves, R; Carvalho, D; Portela, F; Dias, C; Dignass, A; Danese, SBackground: Ulcerative colitis (UC) has been the focus of numerous observational studies over the years and a common strategy employed in their design is the use of composite and aggregate outcomes. Objective: This systematic review and meta-analysis aims to identify composite and aggregate outcomes of observational studies in UC and to evaluate how the number and type of variables included and the length of fo...
Genetic Variants of the MGAT5 Gene Are Functionally Implicated in the Modulatio...
Pereira, MS; Durães, C; Catarino, TA; Costa, JL; Cleynen, I; Novokmet, M; Krištic, J; Štambuk, J; Conceição-Neto, N; Machado, JC; Marcos-Pinto, ROBJECTIVES: The impact of genetic variants (single nucleotide polymorphisms [SNPs]) in the clinical heterogeneity of ulcerative colitis (UC) remains unclear. We showed that patients with UC exhibit a deficiency in MGAT5 glycogene transcription in intestinal T cells associated with a hyperimmune response. Herein, we evaluated whether MGAT5 SNPs might functionally impact on T cells glycosylation and plasma IgG gl...
Low Golimumab Trough Levels at Week 6 Are Associated With Poor Clinical, Endosc...
Magro, F; Lopes, S; Silva, M; Coelho, R; Portela, F; Branquinho, D; Correia, L; Fernandes, S; Cravo, M; Caldeira, P; Sousa, H T; Patita, M; Lago, PBackground and aims: Golimumab has an established exposure-response relationship in patients with ulcerative colitis [UC]. However, the association of serum golimumab trough levels [TL] with objective markers of disease activity, such as endoscopic and histological activity scores and concentrations of biomarkers, remains less understood. This report describes the relationship of serum golimumab TL at the end o...
Accuracy of the new rapid test for monitoring adalimumab levels
Rocha, C; Afonso, J; Lago, P; Arroja, B; Vieira, AI; Dias, CC; Magro, FThe loss of response to adalimumab (ADL) has been related to low serum concentrations at trough. Currently, most methods commercially available for the quantification of ADL are enzyme-linked immunosorbent assay (ELISA) based, with a turnaround time of approximately 8 h, delaying the target dosage adjustment to the subsequent infusion. In this study, we aimed to evaluate the performance of the newly available r...
Soluble Human Suppression of Tumorigenicity 2 Is Associated with Endoscopic Act...
Magro, F; Lopes, S; Silva, M; Coelho, R; Portela, F; Branquinho, D; Correia, L; Fernandes, S; Cravo, M; Caldeira, P; Tavares de Sousa, H; Patita, MBackground: Suppressor of Tumorigenicity 2 (ST2) is an IL33 receptor detected in the mucosa and serum of ulcerative colitis (UC) patients. We evaluated soluble ST2 (sST2) as a surrogate biomarker of disease outcome and therapeutic response, in moderate-to-severe UC patients treated with golimumab. Methods: We conducted an open-label single-arm multicentre prospective study. At screening/baseline, week 6 (W6) an...
The who-when-why triangle of CAM use among Portuguese IBD patients
Portela, F; Dias, C; Caldeira, P; Cravo, M; Deus, JR; Gonçalves, R; Lago, P; Morna, H; Peixe, P; Ramos, J; Sousa, H; Tavares, L; Vasconcelos, HThe use of complementary and alternative medicines is increasing among chronic patients, particularly those afflicted with inflammatory bowel diseases. AIM: This study aimed to address the prevalence of complementary and alternative medicines use among Portuguese inflammatory bowel diseases' patients. METHODS: Patients were invited to fill an anonymous questionnaire concerning the use of complementary and alter...

Assessment of Continuous Pain in Newborns Admitted to NICUs in 18 European Coun...
Anand, K; Eriksson, M; Boyle, E; Avila-Alvarez, A; Andersen, R; Sarafidis, K; Polkki, T; Matos, C; Lago, P; Papadouri, T; Attard-Montalto, S; Ilmoja, MLAIM: Continuous pain occurs routinely, even after invasive procedures, or inflammation and surgery, but clinical practices associated with assessments of continuous pain remain unknown. METHODS: A prospective cohort study in 243 neonatal intensive care units (NICUs) from 18 European countries recorded the frequency of pain assessments, use of mechanical ventilation, sedation, analgesia or neuromuscular blockade...
Association between Polymorphisms in Antioxidant Genes and Inflammatory Bowel D...
Pereira, CC; Durães, C; Coelho, R; Grácio, D; Silva, M; Peixoto, A; Lago, P; Pereira, M; Catarino, T; Pinho, S; Teixeira, JP; Macedo, G; Annese, VInflammation is the driving force in inflammatory bowel disease (IBD) and its link to oxidative stress and carcinogenesis has long been accepted. The antioxidant system of the intestinal mucosa in IBD is compromised resulting in increased oxidative injury. This defective antioxidant system may be the result of genetic variants in antioxidant genes, which can represent susceptibility factors for IBD, namely Croh...
