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...
Screening a Targeted Panel of Genes by Next-Generation Sequencing Improves Risk...
Matos, S; Bernardo, P; Esteves, S; Botelho de Sousa, A; Lemos, M; Ribeiro, P; Silva, M; Nunes, A; Lobato, J; Frade, MJ; Gomes da Silva, M; Chacim, SAlthough mutation profiling of defined genes is recommended for classification of acute myeloid leukemia (AML) patients, screening of targeted gene panels using next-generation sequencing (NGS) is not always routinely used as standard of care. The objective of this study was to prospectively assess whether extended molecular monitoring using NGS adds clinical value for risk assessment in real-world AML patients...
Management of ibrutinib treatment in patients with B-cell malignancies: clinica...
Carda, JP; Santos, L; Mariz, JM; Monteiro, P; Gonçalves, HM; Raposo, J; Silva, MGObjectives: Ibrutinib, a potent inhibitor of the Bruton tyrosine kinase, has revolutionized the treatment of many B-cell malignancies. Ibrutinib has an established favorable toxicity profile with up to 8 years of experience in clinical trials; however, despite ibrutinib’s favorable toxicity profile, dose reductions and treatment discontinuations are becoming more evident in clinical practice, particularly in th...
Budd-Chiari Syndrome and Acute Liver Failure: An Uncommon Presentation of Acute...
Costa, ARG; Freitas, I; Raposo, J; Barbosa, G; Miranda, HP; Nery, FAcute liver failure (ALF) is a rare entity, particularly in the context of Budd-Chiari syndrome (BCS). BCS is an uncommon disorder with multiple risk factors, most commonly myeloproliferative disorders. In BCS, active search and exclusion of underlying malignancy is mandatory, particularly in the context of ALF, as it may contraindicate liver transplantation (LT). We present the case of a healthy 29-year-old ma...
Agonistas dos Receptores do GLP-1 no Tratamento da Diabetes Tipo 2
Carvalho, D; Silva Nunes, J; Raposo, J; Medina, J; Jácome de Castro, J; Carrilho, FA Diabetes Mellitus tipo 2 é um flagelo individual, social e económico, em particular nas sociedades ocidentais. A metformina surge como fármaco de primeira linha na terapêutica farmacológica desta patologia, mas na impossibilidade de controlo metabólico adequado sob esta em monoterapia, as recomendações colocam as restantes classes de fármacos ao mesmo nível, reflectindo uma mudança de paradigma para a individ...
First Diabetic Retinopathy Prevalence Study in Portugal: RETINODIAB Study-Evalu...
Dutra-Medeiros, M; Mesquita, E; Papoila, AL; Genro, V; Raposo, JBACKGROUND/AIMS: In Portugal, so far, there is no study or even accurate data on the prevalence of diabetic retinopathy (DR), based on a large representative sample and on a long-term follow-up. The objective of our study was to determine the prevalence of DR based on a national screening community-based programme. METHODS: A 5-year retrospective analysis of the RETINODIAB screening programme results was implem...
A mathematical model of calcium and phosphorus metabolism in two forms of hyper...
Raposo, J; Pires, A; Yokota, H; Ferreira, HParathyroid hormone (PTH) plays a critical role in calcium and phosphorus metabolism. Interestingly, in two forms of hyperparathyroidism (excessive amount of PTH in the serum), the metabolic disturbances in patients with chronic kidney disease (CKD) significantly differ from those with primary hyperparathyroidism (PHP). Since an intuitive understanding of these PTH-linked regulatory mechanisms are hardly possib...
Carcinoma Oculto da Mama com Metástases Axilares. A Propósito de Dois Casos Clí...
Condeço, R; Santos, P; Raposo, J; Pereira, M; Pereira, H; Martins, M; Marcos, F; Morujão, I; Lopes, P; Vitorino, C; Correia, A; Costa, L; Albuquerque, JINTRODUÇÃO: O carcinoma oculto é uma entidade pouco frequente, que se define como a presença de metástases com tumor primário indetetável na altura da apresentação. O prognóstico da maioria dos casos de tumor oculto é reservado, no entanto, o desenvolvimento de técnicas imunohistoquímicas que permitem a caracterização do tumor, tornaram alguns subgrupos de tumor oculto potencialmente curáveis. A presença de ade...
Model-based analysis of FGF23 regulation in chronic kidney disease
Yokota, H; Pires, A; Raposo, J; Ferreira, HThe mechanism of FGF23 action in calcium/phosphorus metabolism of patients with chronic kidney disease (CKD) was studied using a mathematical model and clinical data in a public domain. We have previously built a physiological model that describes interactions of PTH, calcitriol, and FGF23 in mineral metabolism encompassing organs such as bone, intestine, kidney, and parathyroid glands. Since an elevated FGF23 ...
Aplastic anemia. Alternative treatment by bone marrow transplantation.
Fonseca, T; Raposo, J; Gomez, B; d'Oliveira, J J; de Lacerda, J MWe report a case of a 25-year-old woman, with the diagnosis of severe aplastic anemia without a histocompatible sibling donor for bone marrow transplantation. The patient has been treated successfully with a combination of two immunosuppressive agents, cyclosporine and antilymphocyte globulin, after not responding to primary therapy with corticosteroids and growth factors. She showed a complete response to trea...
