a clinical perspective

This article was funded by the project NORTE-08-5369-FSE-000018, supported by Norte Portugal Regional Programme (Norte2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF) and by FCT—Fundação para a Ciência e a Tecnologia [UID/ BIM/04293/2013].Background: In phenylketonuria (PKU), modified casein glycomacropeptide supplements (CGMP-AA) are used as an alternative to the traditional phenylalanine (Phe)-free L-amino acid supplements (L-AA). However, studies focusing on the long-term nutritional status of CGMP-AA are lacking. This retrospective study evaluated the long-term impact of CGMP-AA over a mean of 29 months in 11 patients with a mean age at CGMP-AA onset of 28 years (range 15–43) [8 females; 2 hyperphenylalaninaemia (HPA), 3 mild PKU, 3 classical PKU and 3 late-diagnosed]. Outcome measures included metabolic control, anthropometry, body composition and biochemical parameters. Results: CGMP-AA, providing 66% of protein equivalent intake from protein substitute, was associated with no significant change in blood Phe with CGMP-AA compared with baseline (562 ± 289 µmol/L vs 628 ± 317 µmol/L; p = 0.065). In contrast, blood tyrosine significantly increased on CGMP-AA (52.0 ± 19.2 μmol/L vs 61.4 ± 23.8 μmol/L; p = 0.027). Conclusions: Biochemical nutritional markers remained unchanged which is an encouraging finding in adults with PKU, many of whom are unable to maintain full adherence with nutritionally fortified protein substitutes. Longitudinal, prospective studies with larger sample sizes are necessary to fully understand the metabolic impact of using CGMP-AA in PKU.publishersversionpublishe

Perfil epidemiológico de casos notificados da doença falciforme no Ceará / Epidemiological profile of notified cases of sickle cell disease in Ceará

Introdução: A doença falciforme é uma das doenças mais comuns no mundo, é hereditária e caracteriza-se pela presença da hemoglobina S. O Programa Nacional de Triagem Neonatal tem proporcionado o diagnóstico precoce da doença falciforme em neonatos, contribuindo para melhor qualidade de vida dos casos confirmados. Objetivo: descrever o perfil epidemiológico quanto aos aspectos sócio demográficos e clínicos da doença falciforme. Métodos: Trata-se de estudodescritivo com dados secundários registrados de 1994 a 2018, que incluíram dados de prontuários de 668 pacientes com a doença falciforme no Estado do Ceará entre os anos de 1964 e 2018, por meio do sistema de informação de três unidades de referência, com atendimento do Sistema Único de Saúde. Realizou-se a descrição das variáveis por meio do cálculo das médias, medianas, frequência absoluta e relativa. Resultados: Observou-se que a maioria dos casos foi encontrado em Fortaleza (74,4%) com atendimento na hemorrede (51,5%). As mulheres foram maioria (53%), sendo a cor parda a de maior predominância (69%). Os dados clínicos da maioria dos casos apresentaram prevalência de hemoglobinopatia SS (HbSS) (69,9%), necessidade de transfusões (53,3%), crise álgica (54,9%), pneumonia (17,1%) e utilização de ácido fólico (89,1%). Conclusão: As mulheres e pessoas de cor parda representaram a maioria da amostra com anemia falciforme ao longo de meio século. Observou-se predominância da Hemoglobinopatia do tipo HbSS e ocorrência de transfusões, sem informações quanto ao número de sessões realizadas

The complete genome sequence of Chromobacterium violaceum reveals remarkable and exploitable bacterial adaptability

Chromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spread utilization of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in addition, a series of previously unknown but important enzymes and secondary metabolites including paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multiple chitinases, and proteins for the detoxification of xenobiotics that may have biotechnological applications

Experience of the spouse of a woman with breast cancer undergoing chemotherapy: a qualitative case study

Abstract Objective: To identify the meaning attributed to the experience of a spouse of a woman with breast cancer undergoing chemotherapy. Methods: Descriptive study, with a theoretical-methodological orientation based on medical anthropology and utilizing an ethnographic case study strategy. Data were collected through semi-structured interviews and participant observation. Results: The meanings revealed that the diagnosis cause suffering. Chemotherapy was seen as giving hope of healing the wife's cancer. During this process, the spouse had to deal with the strong adverse effects of the treatment and subordinate to his wife to reduce the conflict experienced by the couple, which violated the rules of his masculinity. Religion and family were important support networks on this path. Final considerations and implications for practice: The results showed the importance of considering cultural aspects of spouses when they are faced with disease in their wives. The way spouses deal with breast cancer will depend on their cultural systems. Nursing care must be comprehensive and extend to spouses whose wives have breast cancer

The first case of type F botulism, in Portugal

Poster abstract publicado em: Toxicon. 2016;123(Suppl. 25):S55-6. Disponível em: https://doi.org/10.1016/j.toxicon.2016.11.157The first case in Portugal of type F botulism was identified in July 2016. Type F botulinum toxin (BoNT/F) was detected and a BoNT/F producing strain was isolated in the stool of a patient with clinical signs of botulism. Worldwide, few cases of type F botulism have been reported in adults. Most cases of botulism described in humans have been caused by toxins of type A, B or E. The microorganisms that have been identified as producers of toxin F are C. botulinum and C. baratii. Ingestion of contaminated food or, more rarely, wound infection, toxin production in the intestinal tract if immunologically immature (infant botulism) or intestinal colonization in the adult, can produce the clinical syndrome of botulism.N/

The in vivo and in vitro roles of Trypanosoma cruzi Rad51 in the repair of DNA double strand breaks and oxidative lesions.

In Trypanosoma cruzi, the etiologic agent of Chagas disease, Rad51 (TcRad51) is a central enzyme for homologous recombination. Here we describe the different roles of TcRad51 in DNA repair. Epimastigotes of T. cruzi overexpressing TcRAD51 presented abundant TcRad51-labeled foci before gamma irradiation treatment, and a faster growth recovery when compared to single-knockout epimastigotes for RAD51. Overexpression of RAD51 also promoted increased resistance against hydrogen peroxide treatment, while the single-knockout epimastigotes for RAD51 exhibited increased sensitivity to this oxidant agent, which indicates a role for this gene in the repair of DNA oxidative lesions. In contrast, TcRad51 was not involved in the repair of crosslink lesions promoted by UV light and cisplatin treatment. Also, RAD51 single-knockout epimastigotes showed a similar growth rate to that exhibited by wild-type ones after treatment with hydroxyurea, but an increased sensitivity to methyl methane sulfonate. Besides its role in epimastigotes, TcRad51 is also important during mammalian infection, as shown by increased detection of T. cruzi cells overexpressing RAD51, and decreased detection of single-knockout cells for RAD51, in both fibroblasts and macrophages infected with amastigotes. Besides that, RAD51-overexpressing parasites infecting mice also presented increased infectivity and higher resistance against benznidazole. We thus show that TcRad51 is involved in the repair of DNA double strands breaks and oxidative lesions in two different T. cruzi developmental stages, possibly playing an important role in the infectivity of this parasite
