Angola renasce : um estudo sobre as perspectivas de ampliação das relações económicas entre Portugal e Angola

O objetivo deste trabalho é a identificação dos produtos portugueses, a quatro dígitos da Nomenclatura Combinada (NC), com maiores perspetivas de ampliação de comércio em Angola, através da avaliação da competitividade exportadora portuguesa e do dinamismo importador angolano. Usamos o Índice de Vantagem Comparativa Revelada (IVCR) para analisar a competitividade exportadora portuguesa, e apuramos o dinamismo importador angolano através da avaliação daqueles produtos que apresentaram maior crescimento das importações, no período de referência deste estudo (2005 a 2009). Além disso, identificou-se o grau de intensidade tecnológica desses produtos com maior potencial de crescimento das exportações portuguesas para a Angola. A análise qualitativa desses produtos mostrou que eles são, na sua maioria, de média-baixa e média-alta intensidade tecnológica e residualmente de baixa tecnologia, não existindo commodities ou produtos com alta intensidade tecnológica. Outro aspecto importante deste estudo é a constatação que os produtos identificados pela metodologia utilizada já se encontram na pauta de exportações efetivas de Portugal para Angola, embora os produtos com maior IVCR não sejam necessariamente os produtos mais exportados.N/

Effect of an educational nursing intervention on the mental adjustment of patients with chronic arterial hypertension: an interventional study

The objective of this analytical and interventional prospective quantitative study was to assess the effect of an educational intervention performed by nurses for mental adjustment to chronic disease in patients with hypertension. A convenience sample was studied, composed of 329 participants with chronic hypertension, followed in a primary healthcare unit in the Central Region of Portugal. Data collection was carried out by applying the Mental Adjustment to Disease Scale (MADS) before and 1 month after the educational nursing intervention between September 2017 and February 2018. Prior to the application of the educational intervention, 43.5% of the participants were classified as “unadjusted” in at least one of the subscales of MADS. After the educational intervention, 21.3% of the participants classified as “unadjusted” became “adjusted” in all MADS subscales. The success rate of the intervention varied from 26.9% (in the fatalism subscale) to 44.6% (for the anxious concern subscale). Participants were more likely to be mentally “unadjusted” to hypertension if they lived with other family members, had an active professional situation before the diagnosis of hypertension, still had an active professional situation now, were under 65 years old, had a shorter time to diagnosis (1–2 years), and measured blood pressure less regularly. The educational intervention performed by nurses is relevant for the mental adjustment of hypertensive patients, contributing to increased knowledge, as well as improvement in preventive and self-care practices, facilitating the experience of the health/disease transition process.publishe

Simulation of pace maker implantation for medical imaging professionals training

The learning process in a simulation context envisages the students to integrate a realistic situation probable in their professional future, in which they feel the difficulties, try to overcome them and acquires a real perception of the working environment. The greatest advantage of learning in a simulation context relies on the promotion of deep knowledge, since the student effectively participates in the scenario, instead of only being a passive element in the learning process [1]. In this work, a simulation of a pace maker implantation with imaging support requirement took place at the Clinical Simulation Centre of the University of Aveiro, "Simula", with the purpose of training future medical imaging professionals. The main objectives were to enhance and develop technical, problem-solving and interpersonal skills as well as to implant teamwork values [1].publishe

COMPOSTAGEM COMO ALTERNATIVA DE DESTINAÇÃO PARA O LODO FLOTADO DE ABATEDOURO DE FRANGOS

Qualquer atividade humana leva à produção de resíduos, no entanto a sociedade exige continuamente a manutenção e melhoria das condições ambientais, onde diversas técnicas de reaproveitamento ou transformação de resíduos podem ser utilizadas. Uma das técnicas que vem sendo amplamente empregada é a compostagem, onde ocorre a degradação biológica, aeróbica ou anaeróbica de resíduos orgânicos, de modo a produzir uma substância húmica para condicionar o solo. Os abatedouros de frangos constituem-se de grandes fontes geradores de poluição principalmente das águas. Dessa forma o presente trabalho relata a aplicação da compostagem como forma de disposição do lodo gerado no tratamento de efluentes de um abatedouro de frangos. Foram aplicados três tratamentos diferenciados e avaliou-se alguns parâmetros como temperatura, odor, moscas, formigas, larvas na leira, chorume e larvas no chorume e umidade, pH, Nitrogênio, Fósforo, Carbono e potássio. Os resultados apresentaram-se satisfatórios, havendo para cada parâmetro suas particularidades em aspectos positivos e negativos

Overexpression of Adenosine A2A receptors in rats: effects on depression, locomotion, and anxiety

Although this reciprocal antagonistic interaction is well-established in motor function, the outcome in dopamine-related behaviors remains uncertain, in particular in depression and anxiety. We have demonstrated an upsurge of A2AR associated to aging and chronic stress. Furthermore, Alzheimer's disease patients present A2AR accumulation in cortical areas together with depressive signs. We now tested the impact of overexpressing A2AR in forebrain neurons on dopamine-related behavior, namely depression. Adult male rats overexpressing human A2AR under the control of CaMKII promoter [Tg(CaMKII-hA2AR)] and aged-matched wild-types (WT) of the same strain (Sprague-Dawley) were studied. The forced swimming test (FST), sucrose preference test (SPT), and the open-field test (OFT) were performed to evaluate behavioral despair, anhedonia, locomotion, and anxiety. Tg(CaMKII-hA2AR) animals spent more time floating and less time swimming in the FST and presented a decreased sucrose preference at 48 h in the SPT. They also covered higher distances in the OFT and spent more time in the central zone than the WT. The results indicate that Tg(CaMKII-hA2AR) rats exhibit depressive-like behavior, hyperlocomotion, and altered exploratory behavior. This A2AR overexpression may explain the depressive signs found in aging, chronic stress, and Alzheimer's disease.Joana E. Coelho, Vânia L. Batalha and Diana G.

Multicomponent systems with cyclodextrins and hydrophilic polymers for the delivery of Efavirenz

AbstractEfavirenz (EFZ) is one of the most used drugs in the treatment of AIDS and is the first antiretroviral choice. However, since it has low solubility, it does not exhibit suitable bioavailability, which interferes with its therapeutic action and is classified as a class II drug according Biopharmaceutical Classification System (low solubility and high permeability). Among several drug delivery systems, the multicomponent systems with cyclodextrins and hydrophilic polymers are a promising alternative for increasing the aqueous solubility of the drug. The present study aimed to develop and characterize in a ternary system of EFZ, MβCD and PVP K30. The results showed that the solid ternary system provided a large increase in the dissolution rate which was greater than 80% and was characterized by DSC, TG, XRD, FT-IR and SEM. The use of the ternary system (EFZ, MβCD and PVP K30 1%) proved to be a viable, effective and safe delivery of the drug. The addition of the hydrophilic polymer appeared to be suitable for the development of a solid oral pharmaceutical product, with possible industrial scale-up and with low concentration of CDs (cyclodextrins)
