The authors report a case of a male patient from Bacabal, MA with diffuse cutaneous leishmaniasis (DCL), for at least nine years, with 168 lesions on his body. These were tumour-like nodules with some ulceratmi. He usedpentavalent antimonial (glucantime®) and an association of gamma interferon plus glucantime with improvement of the lesions but relapsed later. Recently, pentamidine isethionate (pentacarinat®) was given a dosage of 4mg/kg/weight/day on alternate days for 20 applications. After 3 months a similar course of 10 application was given 2 times. Later he developed diabetic signs with weight loss of 10kg, polydypsia, polyuria and xerostomia. The lower limbs lesions showed signs of activity. Blood glucose levels normalised and remain like this at moment. Attention is drawn to the fact that pentamidine isethionate should be used as a therapy option with care, obeyng rigorous laboratory controls including a glucose tolerance test.

RESUMO: Em 2006, foi aprovada uma nova política governamental para a saúde mental intitulada “Uma Visão para a Mudança”, a qual está neste momento no sétimo ano de implementação. A política descreve um enquadramento para o desenvolvimento e promoção da saúde mental positiva para toda a Comunidade e para a prestação de serviços acessíveis, baseados na comunidade, serviços especializados para pessoas com doença mental. A implementação da política e o tornar a “Vision for Change” uma realidade têm sido problemáticos, com críticas consideráveis por parte dos intervenientes, relativas à lenta e desconexa implementação. Este estudo fornece informação sobre as características dos serviços de três importantes tipos de instituições de saúde mental comunitária a nível nacional, nomeadamente Hospitais de Dia, Centros de Dia e residências comunitárias operantes 24 horas. A pesquisa analisa objetivos e funções, perfis dos pacientes, atividades terapêuticas, a eficácia das redes de comunicação e beneficia da perspectiva dos funcionários sobre o que mudou no terreno ao longo dos últimos sete anos. As questões identificadas a partir das características dos três serviços dizem respeito a todos. Os participantes indicaram que o ethos da recuperação parece ter alcançado um papel mais central no tratamento do paciente na comunidade mas reconheceram que o desafio de integrar os princípios de recuperação na prática clínica se mantém presente. Parece ser reconhecida a importância da planificação do cuidado individual nos serviços comunitários e os entrevistados indicaram que existe um empenho para garantir o envolvimento do usuário do serviço. Há diferenças entre os „pontos de vista do pessoal‟ e os „pontos de vista dos representantes‟ sobre uma série de aspetos da prestação de serviços. Este é o primeiro estudo irlandês deste género a examinar a prestação de serviços das três principais instituições comunitárias de saúde mental num só estudo. Estes serviços representam um enorme investimento em recursos, quer a nível monetário, quer humano. O estudo examinou os desafios e as questões fundamentais que lhe são aplicáveis e que têm impacto nestes três tipos de prestação de serviços. Também forneceu informações sobre os elementos de mudança positiva, os quais se começam a focar lentamente na prestação do serviço, assim como na importância da centralidade do utilizador do serviço e na promoção de um ethos da recuperação.----------ABSTRACT: In 2006, a new Government policy for mental health “A Vision for Change” was endorsed and is currently in the seventh year of implementation. The policy describes a comprehensive framework for building and fostering positive mental health across the entire community and for providing accessible, community based, specialist services for people with mental illness. The implementation of the policy and turning “Vision for Change” into reality has been problematic with considerable criticism from stakeholders concerning slow and disjointed implementation. This study provides information on three key community mental health service settings, namely Day Hospitals, Day Centres and 24 Hour Community Residences at a national level. The research looks at aims and functions, patient profiles, therapeutic activities, effectiveness of key communication networks and gains an insight from staff on what has changed on the ground over the past seven years. Issues identified from the three service settings pertain to all. Participants indicated that the recovery ethos appears to have moved to a more central role in patient care in the community but acknowledged that the challenge of integrating recovery principles in clinical practice remains present. The importance of individual care planning appears to be recognised in community services and respondents indicated that efforts are being made to ensure service user involvement. There were differences between „staff views‟ and „advocate views‟ on a number of aspects of service provision. This is the first Irish study of its kind to examine service provision across the three main community mental health settings in one study. These services represent a huge investment in resources both on a monetary and human level. This study has examined the challenges and key issues which are applicable and impacting on all three types of service provision. It has also provided information on the elements of positive change, which are slowly embedding themselves in service provision such as the importance of the centricity of the service user and the promotion of a recovery ethos.

Three texts were prepared for delivery at the first honorary doctorate awarded simultaneously by three Lisbon universities on 27 February, 2012: an introduction, a lecture and a comment. The event included the award of member of the Lisbon Academy of Science (ACL) by Manuel Jacinto Nunes, dean of the economics and finance section of ACL who proposed his name and Olivier Blanchard’s on the 30th anniversary of James Tobin receiving an honorary doctorate from Nova University. On 24 February , Paul Krugman visited ACL and participated in a session of the project dubbed “Letter to the lusofonia Queen”. Since this project is promoted by Nova SBE’s Center for Globalization and Governance and has been featured in some of the graduate courses, a short note on the meeting is included in annex. On 15 June, the three universities authorized an edition in Portuguese and donated the copyrights to a student award on “Krugman economics”, in a way still to be determined by the editor. The lecture and the comment will be translated as soon as a suitable publisher is found. Since a lot of the teaching at Nova SBE is in English, it seemed appropriate to reproduce the original texts in the order in which they were presented. A lively question and answer period was also recorded by Nova TV and should be made available in the book, together with highlights of the media coverage. Introduced as a “militant economist”, he speaks about a crisis “his mind loves but does not let the heart forget the poor and the unemployed”. The Nobel prize winner described as a“progressist pessimist of the world economy” concludes with a severe indictment of the profession. “In normal times, when things are going pretty well, the world can function reasonably well without professional economic advice. It’s in times of crisis, when practical experience suddenly proves useless and events are beyond anyone’s normal experience, that we need professors with their models to light the path forward. And when the moment came, we failed”. The comment, by the official responsible for Paul Krugman’s mission to Portugal in 1976, contains an equally dire prediction: “I would very much like to see in the near future the weakening of the influence not only of freshwater economists but also of their conservative European followers. But I fear that this will not happen until we find ourselves in a more calamitous situation than at present”. Fortunately Silva Lopes closes in the hope “that the ideas of Paul Krugman will soon have more influence in policy makers than at present seems to be the case”.

This work demonstrates that deltamethrin in low doses produces an excito-repellency effect on triatomines, as already observed for mosquitoes. A wooden box covered with a cloth impregnated with deltamethrin at doses of 2.5 and 5mg ai/m² was utilized for the experiment. The triatomine species studied were Triatoma infestans, Panstrongylus megistus, Rhodnius neglectus and Triatoma sordida. Adults were released in one of the sides of the box and their position was noted in subsequent periods. The observations were realized on the day the cloth was impregnated and subsequently repeated at 30 and 60 days for T. sordida; on day 120, the remaining species were included. Insect mortality and attempts at flight from the box were also observed. Excito-repellency was evident for all species and doses up to day 120. The only species that attempted to fly was P. megistus. The excito-repellency effect may be considered as an additional advantage to the insecticide power, as it should be able to prevent the installation of new colonies by females that fly into the homes, and at the moment of the spraying, it should promote the flushing out of triatomines from the wall crevices and from other shelters.

Considering Alan Turing’s challenge in «Computing Machinery and Intelligence» (1950) – can machines play the «imitation game»? – it is proposed that the requirements of the Turing test are already implicitly being used for checking the credibility of virtual characters and avatars. Like characters, Avatars aim to visually express emotions (the exterior signs of the existence of feeling) and its creators have to resort to emotion codes. Traditional arts have profusely contributed for this field and, together with the science of anatomy, shaped the grounds for current Facial Action Coding System (FACS) and their databases. However, FACS researchers have to improve their «instruction tables» so that the machines will be able, in a near future, to be programmed to carry out the operation of recognizing human expressions (face and body) and classify them adequately. For the moment, the reproductions have to resort to the copy of real life expressions, and the presente smile of avatars comes from mirroring their human users.

Portugal was one of the first and most enduring European colonial powers of modern times: 1415 and 1975 mark the beginning and the end of a long empire cycle that left impressive imprints in many places. Since it started, the overseas expansion and the exploration of the colonial resources were closely articulated with state-building and the preservation of national independence. A forerunner at the Great Age of Discoveries, but a latecomer in the era of industrialization, in the 19th and early-20th centuries Portugal was a peripheral country, and the economic gap with the rich and industrialized core of Europe was wide. During this period, however, the country faced the critical challenge of ruling vast and geographically scattered overseas territories, and of preserving them from the greed of strong imperialist powers. This article starts by outlining the major developments in the Portuguese colonial policy over a century, since the 1820s until 1926. The independence of Brazil (1822) was a crucial turning point, which brought about a shift towards Africa. The First Republic (1910-1926), pervaded by a nationalist ideology, gave a new impetus to the efforts towards a more effective colonisation. Symptomatically, a Ministry of Colonies was then established for the first time. Second, it describes and analyses the transformation of the central office for colonial affairs – from a small ministerial department to an autonomous ministry -, stressing the increasing bureaucratic specialisation, the growth of the apparatus and its staff, and the introduction of new criteria for the selection and promotion of permanent officials (namely a higher profile given to careers in local colonial administration). Finally, it presents a collective biography of both the politicians (Cabinet ministers) and the administrators (directors-general) who ran the Colonial Office for a large period of the Constitutional Monarchy (from 1851 to 1910) and during the First Republic, thus enabling to assess the impact of regime change on elite circulation and career patterns.

As an introduction to a series of articles focused on the exploration of particular tools and/or methods to bring together digital technology and historical research, the aim of this paper is mainly to highlight and discuss in what measure those methodological approaches can contribute to improve analytical and interpretative capabilities available to historians. In a moment when the digital world present us with an ever-increasing variety of tools to perform extraction, analysis and visualization of large amounts of text, we thought it would be relevant to bring the digital closer to the vast historical academic community. More than repeating an idea of digital revolution introduced in the historical research, something recurring in the literature since the 1980s, the aim was to show the validity and usefulness of using digital tools and methods, as another set of highly relevant tools that the historians should consider. For this several case studies were used, combining the exploration of specific themes of historical knowledge and the development or discussion of digital methodologies, in order to highlight some changes and challenges that, in our opinion, are already affecting the historians' work, such as a greater focus given to interdisciplinarity and collaborative work, and a need for the form of communication of historical knowledge to become more interactive.

This paper addresses the study of a mosaic discovered in 2007 at the archaeological site of Alter do Chão, Portugal, whose central panel represents the penultimate scene narrated in the last Book of the Æneid – a Roman epic composed by the poet Publius Vergilius Maro (70 BC – AD 19), at the request of Gaius Julius Cæsar Octavianus Augustus (63 BC – AD 14): it shows the very moment when Turnus, the Latin king of the Rutuli, kneels before Æneas, considered the precursor to the foundation of Rome (Virgil, Æneid, XII, 926-950).

Cell division is a highly dynamic process where sister chromatids remain associated with each other from the moment of DNA replication until the later stages of mitosis, giving rise to two daughter cells with equal genomes. The “molecular glue” that links sister DNA molecules is called cohesin, a tripartite ring-like protein complex composed of two Structural Maintenance of Chromosome proteins (Smc1 and Smc3) bridged by a kleisin subunit Rad21/Scc1, that together prevent precocious sister chromatid separation. Accumulating evidence has suggested that cohesion decay may be the cause of segregation errors that underlie certain human pathologies. However it remains to be determined how much cohesin loss abolishes functional sister chromatid cohesion. To answer these questions, we have developed different experimental conditions aiming to titrate the levels of cohesin on mitotic chromosomes in a precise manner. Using these tools, we will determine the minimal amount of cohesin needed to confer functional cohesion. The approaches described here take advantage of a system in Drosophila melanogaster where the Tobacco Etch Virus (TEV) protease can cleave the Rad21 subunit of cohesin leading to precocious sister chromatid separation. Firstly, we tried to express different levels of TEV protease to obtain partial loss of cohesion. However, this approach has failed to produce systematic different levels of sister chromatid separation. Most of the work was therefore focused on a second strategy, for which we established strains with different levels of cohesin sensitive/cohesin resistant to TEV protease. Strains containing different amounts of functional cohesin (TEV resistant) were tested by in vitro cleavage and by in vivo injections in embryos for their ability to promote sister chromatid cohesion. Our results reveal that removal of half of the cohesin complexes does not impair chromosome segregation, implying that chromosome cohesion is less sensitive to cohesin amounts than previously anticipated.

RESUMO: A população mundial está a envelhecer de forma sustentada. O setor das farmácias em Portugal está a passar por um conjunto de alterações que conduzirá a uma ação mais interventiva ao nível da prestação de cuidados de saúde. Deste modo delineou-se um estudo descritivo, transversal e exploratório sem intervenção, de carácter qualitativo e quantitativo que compara diferentes grupos etários com o objectivo de compreender melhor o papel do farmacêutico no âmbito do envelhecimento das populações. Pretendemos assim optimizar práticas e serviços que podem ser realizados nas farmácias e alertar os utentes, para gerir melhor a sua condição de saúde, sensibilizando-os para o próprio processo de envelhecimento. Como principais resultados destacamos o papel de intervenção crucial da farmácia, quer pela sua acessibilidade quer pela contribuição que pode ter para a condição de saúde das populações. Pela amostra estudada em 100% das farmácias são feitos despistes e controlo da hipertensão arterial e hipercolesterolemia, factores fundamentais no controlo da aterosclerose e das doenças cardiovasculares. Podemos ainda concluir que a farmácia pode ser o elemento de otimização, revisão e reconciliação das terapêuticas dos resistentes em lares e ao domicílio, junto da população 65+. Em termos das pessoas idosas, o nosso estudo indicia que, apesar da crise sócio económica dos últimos anos, continuam a tomar os medicamentos mais essenciais, o que se relaciona com a política do medicamento implementada. Este trabalho pretende também, contribuir para o desenvolvimento de uma rede de competências da farmácia ao nível do envelhecimento ativo, podendo ser uma oportunidade futura.--------------ABSTRACT: World population is getting older in a sustained way. Portuguese community pharmacies are going through a change process, leading to a higher intervention in healthcare delivery. The study designed is descriptive, transversal and exploratory, with no intervention, with a qualitative and quantitative component that compares different age groups. The purpose is to better understand pharmacists’ role in population aging. One of our main goals is to optimize practices and services with potential to be performed in pharmacies and aware patients to better manage their health, becoming more conscious of their aging process. As main results we highlight the intervention of pharmacies, not only by its accessibility but also sustained on the unique contribution pharmacies deliver in the best benefit of populations’ health condition. In the sample studied, 100% of pharmacies perform screening and vigilance of hypertension and hypercholesterolemia, essential for the control of atherosclerosis and cardiovascular diseases. We may also determine the importance of pharmacies intervention over therapeutics optimization, revision and reconciliation in nursing homes and in domicile, mostly focusing patients over 65. In what concerns to elderly population our study indicates that, despite social and economic crises of recent years, the elderly keeps taking its essential medicines, which is related with medicines politics implemented at the present moment. This project intends to pay a relevant contribution to the development of a group of core competencies in pharmacies, related to the promotion of an active and healthy aging process, which represents an important future opportunity for Portuguese Pharmacies.

INTRODUCTION: The purpose of this study was to evaluate risk factors for physical disability at the moment of leprosy diagnosis. METHODS: This is a retrospective, descriptive and exploratory investigation of 19,283 patients with leprosy, registered in the State of Minas Gerais, Brazil, between 2000 and 2005. RESULTS: The risk of Grade 2 disability was 16.5-fold higher in patients with lepromatous leprosy, and 12.8-fold higher in patients presenting the borderline form, compared to patients presenting indeterminate leprosy. The occurrence of more than one thickened nerve increased the odds of a patient developing Grade 2 disability, 8.4-fold. Age <15 years, multibacillary leprosy and no formal education presented 7.0, 5.7 and 5.6 odds of developing physical disability, respectively. CONCLUSIONS: These factors should be considered as strong prognostic indicators in the development of physical disability at diagnosis.

The superfluous consumption of energy is faced by the modern society as a Socio-Economical and Environmental problem of the present days. This situation is worsening given that it is becoming clear that the tendency is to increase energy price every year. It is also noticeable that people, not necessarily proficient in technology, are not able to know where savings can be achieved, due to the absence of accessible awareness mechanisms. One of the home user concerns is to balance the need of reducing energy consumption, while producing the same activity with all the comfort and work efficiency. The common techniques to reduce the consumption are to use a less wasteful equipment, altering the equipment program to a more economical one or disconnecting appliances that are not necessary at the moment. However, there is no direct feedback from this performed actions, which leads to the situation where the user is not aware of the influence that these techniques have in the electrical bill. With the intension to give some control over the home consumption, Energy Management Systems (EMS) were developed. These systems allow the access to the consumption information and help understanding the energy waste. However, some studies have proven that these systems have a clear mismatch between the information that is presented and the one the user finds useful for his daily life, leading to demotivation of use. In order to create a solution more oriented towards the user’s demands, a specially tailored language (DSL) was implemented. This solution allows the user to acquire the information he considers useful, through the construction of questions about his energy consumption. The development of this language, following the Model Driven Development (MDD) approach, took into consideration the ideas of facility managers and home users in the phases of design and validation. These opinions were gathered through meetings with experts and a survey, which was conducted to the purpose of collecting statistics about what home users want to know.

Carbon dioxide valorization, will not only help to relieve the greenhouse effect but might also allow us to transform it in value-added chemicals that will help overcoming the energy crisis. To accomplish this goal, more research that focus on sequestering CO2 and endeavors through a carbon-neutral or carbon-negative strategy is needed in order to handle with the dwindling fossil fuel supplies and their environmental impact. Formate dehydrogenases are a promising means of turning CO2 into a biofuel that will allow for a reduction of greenhouse gas emissions and for a significant change to the economic paramount. The main objective of this work was to assess whether a NAD+-independent molybdenum-containing formate dehydrogenase is able to catalyze the reduction of CO2 to formate. To achieve this, a molybdenum-containing formate dehydrogenase was isolated from the sulfate reducing bacteria Desulfovibrio desulfuricans ATCC 27774. Growth conditions were found that allowed for a greater cellular mass recovery and formate dehydrogenase expression. After growth trials, kinetic assays for formate oxidation and CO2 reduction were performed and kinetic parameters determined. For the formate oxidation reaction, a KM of 49 μM and a turnover constant of 146 s-1 were determined. These kinetic parameters are in agreement with those determined by Mota, et al. (2011). Finally, we found that this molybdenum-containing enzyme was able to catalyze the reduction of CO2 to formate with a turnover constant of 4.6 s-1 and a KM of 13 μM. For the first time a NAD+-independent molybdenum-containing formate dehydrogenase was found to catalyze CO2 reduction, allowing its use as a biocatalyst in energetically efficient CO2 fixation processes that can be directed towards bioremediation or as an alternative and renewable energy source. Characterizing these enzymes may lead to the development of more efficient synthetic catalysts, make them readily available and more suited for practical applications.

RESUMO - A qualidade e segurança são pilares essenciais dos sistemas de saúde modernos. A sua monitorização e avaliação tem como primeiro passo o conhecimento da realidade no que se refere aos eventos adversos que afetam os utentes. Existem diversas metodologias de medição de eventos adversos. A revisão de processos clínicos, apesar de constituir o padrão de ouro, não permite, ao contrário da análise dos dados administrativos, avaliar de forma abrangente, os episódios de internamento. Esta metodologia a partir de dados recolhidos rotineiramente em inúmeros países, como Portugal, apresenta porém diversas limitações, para as quais têm sido instituídas soluções tais como a sinalização do momento de aquisição do diagnóstico, que pela recente instituição não foi utilizada neste trabalho. Num hospital do Sistema nacional de saúde em Portugal, pela análise dos dados administrativos, determinou-se nos episódios de internamento cirúrgico uma incidência de 2,5% de eventos adversos. Comprovou-se a relação de idade, sexo masculino e admissão urgente com a sua ocorrência. Os doentes que sofreram um evento adverso apresentaram uma probabilidade de óbito bastante superior (odds ratio 12,2) e apresentaram tempos de internamento médio prolongados em cerca de vinte dias. Estes dados não são contudo ajustados para o risco do doente e das intervenções a que são sujeitos. Se forem considerados os tempos de internamento das tabelas de GDH em Portugal, o prolongamento do internamento é de 8,4 dias. A avaliação dos custos adicionais, realizada pelos dias de internamento adicionais, está condicionada à questão metodológica atrás reportada, estimando-se implicações de 1,1% a 8,8% de dias de internamento, com custos de 1.000.000 a 8.600.000 Euros. Em Portugal a monitorização sistemática da ocorrência de eventos, e consequentemente das implicações para a saúde do doente e custos financeiros, não é ainda uma realidade. A implementação do código "presente na admissão" permitirá dar o passo seguinte na utilização dos dados administrativos na compreensão do fenómeno dos eventos adversos.

RESUMO - Contexto: Admite-se a existência de variações no número e nível de experiência dos profissionais de saúde disponíveis nos hospitais durante a noite e o fim-de-semana. As consequências desta situação na qualidade dos cuidados de saúde prestados expõem a importância deste estudo realizado com o objetivo de avaliar o impacto do momento de admissão sobre a mortalidade e a demora média no internamento. Metodologia: Foram estudados 201 369 episódios urgentes, admitidos com um de 36 diagnósticos principais, de acordo com as informações na base de dados dos resumos de alta, para o ano de 2012. O momento de admissão foi definido por período (dias úteis/fim-de-semana) e por hora (dia/noite), e estimaram-se os efeitos fim-de-semana e noite ao nível da mortalidade e da demora média em modelos de regressão logística. Resultados: Registou-se um aumento de 3% no risco de morte, em doentes admitidos ao fim-de-semana. Diferenças que não se verificaram entre os doentes admitidos de dia e de noite. Relativamente à demora média, verificou-se um aumento de 3% na probabilidade dos doentes admitidos durante o fim-de-semana terem uma demora média de internamento superior. Assim como os doentes admitidos durante a noite apresentaram um aumento de 2,9% na probabilidade de terem demora média de internamento mais longa. Conclusão: Os dados apresentados permitem um melhor conhecimento sobre a influência da variação da atividade hospitalar ao longo do dia e da semana nos hospitais portugueses, identificando a necessidade de aprofundar o tema e de implementar medidas que suprimam os efeitos fim-de-semana e noite.
