Enteral Nutrition in Preterm Infants: Update of the National Consensus Document

Na presente actualização da recomendação sobre nutrição entérica no recém-nascido pré-termo, da Secção de Neonatologia da Sociedade Portuguesa de Pediatria, é dada especial relevância às necessidades nutricionais do recém-nascido pré-termo, aspetos particulares da nutrição entérica durante o internamento na unidade neonatal, nomeadamente em relação ao momento de iniciar a nutrição entérica, como progredir, modo de administração, especificidades do leite humano pré-termo, sua fortificação, nutrição em situações particulares e nutrição após alta hospitalar. É incluída informação sobre a composição das fórmulas especiais, fortificante e suplemento proteico do leite humano comercializados em Portugal

Recomendação de Curvas de Crescimento para Crianças Nascidas Pré-Termo

Em 2013, a Secção de Neonatologia da Sociedade Portuguesa de Pediatria, face à existência de várias curvas de avaliação de crescimento para crianças nascidas pré-termo e à falta de homogeneidade de critérios na sua escolha, nomeou um grupo de peritos que procedeu à revisão crítica das curvas disponíveis e recomenda as que considera mais adequadas para utilização na prática clínica em fases específicas da vida: ao nascimento (Fenton 2013), durante o internamento na unidade de Neonatologia (Fenton 2013 e Ehrenkranz 1999) e a longo prazo (OMS 2006). As decisões foram tomadas com base na classificação sistemática do nível de evidência e do grau de recomendação. A presente recomendação: é válida enquanto não forem publicados os resultados do estudo do consórcio multicêntrico INTERGROWTH-21st, recentemente incumbido da construção de valores de referência, mais próximos do padrão, de crianças nascidas pré-termo; tem o propósito de auxiliar os clínicos na decisão clínica, mas não ser o único instrumento de avaliação do crescimento das crianças nascidas pré-termo; pode não proporcionar elementos suficientes para orientação do crescimento de todas estas crianças

Successful treatment of feline leishmaniosis using an association of allopurinol and N-methyl-glucamine antimoniate

This work describes the diagnosis and successful treatment of a 2-year-old domestic cat infected with Leishmania species and presenting fever, and ulcerative and nodular skin lesions after being treated for pyodermatitis for 1 year without clinical improvement. After anamnesis the cat was submitted to a complete clinical examination. Blood was collected for determination of haematological and biochemical parameters, detection of feline leukaemia virus (FeLV), feline immunodeficiency virus (FIV), feline coronavirus (FCoV) and Leishmania amastigotes. Fine-needle aspiration puncture from the skin nodules was also performed. After definitive diagnosis the animal was treated and followed up over a 2 year period. The animal tested negative for FIV-specific antibodies, FeLV antigen and feline coronavirus RNA. Leishmania amastigotes in the skin nodules were confirmed by cytology and molecular diagnosis. Treatment was initiated with allopurinol, resulting in a slight clinical improvement. Thus, N-methyl-glucamine antimoniate was added and administered for 30 days, with complete closure of the ulcerative lesions in the hindlimbs requiring a surgical approach. Close monitoring of the patient in the following 24 months indicated that combined therapy was safe and clinical cure was achieved without further relapses or side effects.publishersversionpublishe

EDDS and EDTA-enhanced zinc accumulation by solanum nigrum inoculated with arbuscular mycorrhizal fungi grown in contaminated soil

The effect of two different chelating agents [EDTA and EDDS S,S-ethylenediaminedissucinic acid)] on Zn tissue accumulation in Solanum nigrum L. grown in a naturally contaminated soil was assessed. Under those conditions, the response of the plant to the inoculation with two different isolates of arbuscular mycorrhizal fungi (AMF) – Glomus claroideum and Glomus intraradices – was also studied. Plants grown in the local contaminated soil (Zn levels of 433 mg Kgˉ¹1) accumulated up to 1191 mg Kgˉ¹ of Zn in the roots, 3747 mg Kgˉ¹ in the stems and 3409 mg Kgˉ¹ in the leaves. S. nigrum plants grown in the same soil spiked with extra Zn (Zn levels of 964 mg Kgˉ¹) accumulated up to 4735, 8267 and 7948 mg Zn Kgˉ¹ in the leaves, stems and roots, respectively. The addition of EDTA promoted an increase in the concentration of Zn accumulated by S. nigrum of up to 231% in the leaves, 93% in the stems and 81% in the roots, while EDDS application enhanced the accumulation in leaves, stems and roots up to 140, 124 and 104%, respectively. In the stems, the presence of Zn was predominantly detected in the cortex collenchyma cells, the starch sheath and the internal phloem and xylem parenchyma, and the addition of chelating agents did not seem to have an effect on the localisation of accumulation sites. The devise of a chelate-enhanced phytoextraction strategy, using chelating agents and AMF, is discussed

Payment for environmental services: a critical review of schemes, concepts, and practice in Brazil.

The Payment for Environmental Services (PES) is often conceived through complex schemes without a clear definition of all concepts involved. This study presents the results of a systematic literature review on PES schemes in Brazil, accompanied by a critical assessment of their efficacy for potential environmental gains. The PES approaches were grouped into six categories based on the research focus, and those that were focused on PES policies were identified as the most studied. A particular emphasis has been given to the Amazon and Atlantic Forest biomes, where the ecosystem services studied were mostly centered on issues related to carbon and water, respectively. Approximately one-third of all schemes provided no clear definition of which ecosystem services are proposed for payment. In addition, the review showed no consensus among studies on the definition of services in similar schemes. Most schemes presented no payment system conditioned on the provision of environmental services. Furthermore, the review showed that the absence of clarity in the application of concepts may hinder the development of public policies to properly implement PES in Brazil. The conclusion is that standardizing terms used in the literature and in PES schemes is critical; therefore, the use of the Common International Classification of Ecosystem Services (CICES) as a reference is recommended to ensure clarity, objectivity and, more importantly, the expected environmental efficacy
