Clinical and genetic factors predicting response to therapy in patients with Cr...
Cravo, Marília; Ferreira, Paula; Sousa, Patrícia; Moura-Santos, Paula; Velho, Sónia; Tavares, Lurdes; Deus, João Ramos; Ministro, PaulaAim - To identify clinical and/or genetic predictors of response to several therapies in Crohn’s disease (CD) patients. Methods - We included 242 patients with CD (133 females) aged (mean ± standard deviation) 39 ± 12 years and a disease duration of 12 ± 8 years. The single-nucleotide polymorphisms (SNPs) studied were ABCB1 C3435T and G2677T/A, IL23R G1142A, C2370A, and G9T, CASP9 C93T, Fas G670A and LgC844T, a...
Glucose-6-Phosphate dehydrogenase deficiency in children from 0 to 14 years hos...
Brito, Miguel; Tchonhi, Chissengo Lucama; Santos, Brígida; Veiga, LuísaThe Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymatic defect in the world. The most common clinical manifestations are acute hemolytic anemia associated with drugs, infections, neonatal jaundice and hemolytic non-spherocytic chronic anemia. The main aim of this study was to determine the frequency of major genetic variants of G6PD leading to enzyme deficiency in children from 0 to...
Epidemiologic transition in northern Angola: discussion of cumulative results f...
Fançony, Cláudia; Pedro, João Mário; Brito, MiguelThe 41 years of armed conflict (1961 to 2002) resulted in a poor development of the health care and education infrastructures, and forced the relocation of people to safer places, namely major urban cities like Luanda. This phase was characterized by typical demographic, nutritional and epidemiological profiles. With the end of this period Angola has been repeatedly ranked as one of the three fastest growing ec...
Effect of deworming on hemoglobin concentration in children from 2 to 15 years ...
Brito, Miguel; Lemos, Manuel; Mirante, Clara; Moura, Sofia; Mayer, CarlosThe most common causes of anemia are micronutrient deficiencies, but other factors may influence namely inflammation, parasitic infections and inherited disorders. One strategy to combat micronutrient deficiencies is supplementation, yet, in zones with high prevalence of Schistosomiasis or Soil Transmitted Helminthes (STH), supplementation could be not sufficient. The aim of this study was to evaluate the effec...
Cytostatics occupational exposure: genotoxic effects assessment
Ladeira, Carina; Viegas, Susana; Carolino, Elisabete; Gomes, M. C.; Brito, MiguelThe use of cytostatics drugs in anticancer therapy is increasing. Health care workers can be occupationally exposed to these drugs classified as carcinogenic, mutagenic or teratogenic. Workers may be exposed to this drug, being in the hospital settings the main focus dwelled upon the pharmacy, and nursing personnel. Although the potential therapeutic benefits of hazardous drugs outweigh the risks of side effect...
Biomonitorization in hospital settings with cytostatics occupational exposure
Ladeira, Carina; Viegas, Susana; Carolino, Elisabete; Gomes, M. C.; Brito, MiguelExposure in a hospital setting is normally due to the use of several antineoplastic drugs simultaneously. Nevertheless, the effects of such mixtures at the cell level and on human health in general are unpredictable and unique due to differences in practice of hospital oncology departments, in the number of patients, protection devices available, and the experience and safety procedures of medical staff. Health...
Desacyl-ghrelin does not influence insulin sensitivity
Veiga, Luísa; Brito, Miguel; Oliveira, Ana; Silva-Fortes, Carina; Silva-Nunes, JoséAcyl-ghrelin has been reported to increase food intake and adiposity and it is the best studied of the orexigenic gastrointestinal hormones. On the other hand, desacyl-ghrelin – DAG (the unacylated form of the hormone) has been reported as a potential player on carbohydrate metabolism. However, the potential impact of DAG on glucose homeostasis remains uncertain. In this study we aim to assess the association b...
Application of alkaline comet assay in human biomonitoring for genotoxicity: a ...
Ladeira, Carina; Viegas, Susana; Carolino, Elisabete; Gomes, M. C.; Brito, MiguelThe use of cytostatics drugs in anticancer therapy is increasing. Health care workers can be occupationally exposed to these drugs classified as carcinogenic, mutagenic or teratogenic. Cytostatics drugs are a heterogeneous group of chemicals widely used in the treatment of cancer, nevertheless have been proved to be also mutagens, carcinogens and teratogens. Workers may be exposed to this drug, being in the hos...
Resultados preliminares do rastreio neonatal de doenças das células falciformes...
Brito, Miguel; Reis, Ana; Tchonhi, Chissengo; Clemente, Isabel; Deus, Inês; Mayer, CarlosAs Hemoglobinopatias são doenças hereditárias com uma prevalência de 10 a 30% de portadores na população africana. As alterações das hemoglobinas envolvem a síntese estrutural e quantitativa dos aminoácidos que compõem as diferentes cadeias de globinas. A Doença das Células Falciformes compreende um grupo de hemoglobinopatias que apresentam um conjunto de sinais e sintomas, sendo a forma mais grave da doença. D...
Diagnóstico da malária em Angola: um país em estreita ligação com Portugal
Moura, S.; Fançony, Cláudia; Mirante, Clara; Neves, M.; Bernardino, L.; Sambo, R.; Barros, H.; Brito, MiguelAs migrações e a globalização dos viajantes têm apresentado grandes desafios no controlo da transmissão de doenças. Em 2012, o número estimado de pessoas em risco de contraíram malária foi de 3,4 biliões. Na Europa, esta é uma doença rara que, em 2012, apenas teve reportados 255 casos autóctones. Para turistas e emigrantes de áreas não endémicas, a malária representa um sério risco de morte e deve ser uma forte...
