This paper studies the political and economic factors that determine successful export diversification (ED) and export sophistication (ES) strategies in the Sub-Saharan African (SSA) countries and also the way in which successful ED and sophistication strategies contribute to explain the improving in some of the millennium development goals (MDG). We run separate regressions for the determinants of ES and ED, using disaggregated data of the 48 SSA countries, from 1960 to 2005. The results suggest that better governance is an important determinant for the success of diversification and sophistication strategies in SSA. In particular the level of corruption, transparency and accountability are important factors in limiting or promoting the scope of diversification and the level of sophistication of the exports. The results also suggest that increases in human capital in SSA countries promote both ED and ES, showing that the level of education of the workforce is positively related with ES and ED, with higher levels of education (tertiary) playing a more important role in explaining ES, while lower levels of education (primary) being more important as determinants of ED. In the second part we explore the links between ED and ES and growth presenting evidence that ED and ES are linked to growth stability in SSA. This study also suggests that the Sub-Saharan countries that were more successful in achieving ED and ES tend to be more successful in improving the living conditions of their population. Using different variables of Infant Mortality (one of the MDG) and life expectancy as dependent variables, we present evidence that suggests that in SSA higher ED and ES are associated with lower infant mortality and higher life expectancy. We show that this result is robust, presenting positive and significant results even when a large number of different control variables are introduced, or when fixed effects and instrumental variables are considered. The evidence suggests that ED and ES are part of the solution for a successful development of SSA.

We assess the determinants of Chinese direct investment in Africa compared with those of global FDI. We find that economic size and macroeconomic stability are positively correlated with Chinese and global FDI in Africa. Institutional variables, such as accountability and rule of law, are not significant in either case and the same can be said about FDI-aid complementarities. The presence of oil is a determinant of Chinese FDI but not of global FDI into Africa. Conversely, the openness of the economy is a determinant for global FDI but not of Chinese FDI, which appears to favour closed economies possibly due to industrial organizational concerns. While these differences accord with intuition, we find no evidence for the claim that Chinese FDI in Africa is related to non-economic governance in a specific way that differs from global practice. More refined governance indicators should be used to verify whether Chinese and global FDI into Africa remain indistinguishable on this score: we plan to do this in future research.

In an endemic area of North-East Brazil (the town of Picos, State of Piauí), a nongovernmental organization (NGO) supported the activity against leprosy in connection with governmental health organizations and local agents. The indicators of leprosy elimination were compared over time (within Picos) and across space (Picos versus Piauí). The case detection rate, above 8 per 10,000 people in the last two years of observation, increased over time in Picos (p=0.010). This finding could be due to active detection activities rather than expanding endemicity, as suggested by the reduction in leprosy in children (p=0.053) and the decrease in the proportion of new cases with grade 2 disability (p<0.001). These indicators showed a more favorable time trend in the city than in the State, suggesting that NGO activity was supportive in the battle towards leprosy control.

This work presents the archaeometallurgical study of a group of metallic artefacts found in Moinhos de Golas site, Vila Real (North of Portugal), that can generically be attributed to Proto-history (1st millennium BC, Late Bronze Age and Iron Age). The collection is composed by 35 objects: weapons, ornaments and tools, and others of difficult classification, as rings, bars and one small thin bent sheet. Some of the objects can typologically be attributed to Late Bronze Age, others are of more difficult specific attribution. The archaeometallurgical study involved x-ray digital radiography, elemental analysis by micro-energy dispersive X-ray fluorescence spectrometry and scanning electron microscopy with energy dispersive spectroscopy, microstructural observations by optical microscopy and scanning electron microscopy. The radiographic images revealed structural heterogeneities frequently related with the degradation of some artefacts and the elemental analysis showed that the majority of the artefacts was produced in a binary bronze alloy (Cu-Sn) (73%), being others produced in copper (15%) and three artefacts in brass (Cu-Zn(-Sn-Pb)). Among each type of alloy there’s certain variability in the composition and in the type of inclusions. The microstructural observations revealed that the majority of the artefacts suffered cycles of thermo-mechanical processing after casting. The diversity of metals/alloys identified was a discovery of great interest, specifically due to the presence of brasses. Their presence can be interpreted as importations related to the circulation of exogenous products during the Proto-history and/or to the deposition of materials during different moments at the site, from the transition of Late Bronze Age/Early Iron Age (Orientalizing period) onwards, as during the Roman period.

A presente dissertação pretende analisar a luta contra a pobreza na Comunidade para o Desenvolvimento da África Austral (SADC), através do estudo do “Caso de Moçambique, 1987 – 2000”. Este estudo analisa também aspetos pertinentes para a Regionalização do Sistema Internacional, dando maior enfase ao surgimento da SADC, os seus obstáculos e a Segurança na região. Relativamente à luta contra a pobreza na Região, Moçambique tem como posição que o combate à pobreza é a forma de luta pela segurança, pois considera um risco existirem “pessoas que vegetam na pobreza e serem facilmente recrutados por grupos interessados em por em causa a segurança mundial, aliás a pobreza provou que é uma ameaça sistémica e sistemática à paz mundial” (Teleinforma 27/09/2013). Neste contexto, este trabalho enfoca o Plano de Ação para a Redução da Pobreza Absoluta (PARPA), estudando o caso do Fundo para o Desenvolvimento Local, vulgo 7 milhões de meticais em Moçambique, alocados anualmente aos Distritos e Municípios. Da pesquisa efetuada verifica-se que, a forma usada para a atribuição do Fundo para o Desenvolvimento Local aos camponeses, não tem sido a mais criteriosa, razão pela qual não reembolsam, depois dos prazos estabelecidos. Nota-se ainda, existência de fraca capacidade de controlo de aplicação pela entidade gestora. Como tal, conclui-se que o Governo tem agido como Banco, vocação que não lhe é competente. Assim, se propõe: a) Criação de um Instituto de Apoio ao Desenvolvimento Local onde cada Distrito teria um Gabinete de Apoio e Monotorização ao Fundo. b) O Gabinete assessoraria os camponeses na promoção dos produtos de forma a rentabilizar os projetos, devido a fraca sensibilização das comunidades locais na gestão do fundo, na elaboração de projetos que possam ser elegíveis ao financiamento bancário.

INTRODUCTION: Human T cell lymphotropic virus type 1 (HTLV-1) is endemic in the Caribbean, Japan, South America and regions of Africa. HTLV-2 is present in Native American populations and associated with IV drug use in Europe and North America. In Brazil, it is estimated that 1.5 million people are infected with HTLV-1/2. The study objective was to determine HTLV-1/2 prevalence in pregnant women in the prenatal care from three public services in São Luis, State of Maranhão, Brazil, and to counsel seropositive women to reduce viral transmission. METHODS: A cross-sectional study was conducted from February to December 2008; women with age of 18 to 45 years, with low risk for sexually transmitted disease (STD) were invited to participate. Blood samples were collected in filter paper, and HTLV-1/2 immunoenzymatic test (ELISA) was performed as a screening test. Women with reactive results were submitted to peripheral venous blood collection for ELISA repetition, followed by Western blot (WB) and real-time PCR to confirm and discriminate the infection between virus types 1 and 2. RESULTS: Of the 2,044 women tested, seven (0.3%) were ELISA reactive and confirmed positive (four were HTLV-1, and three were HTLV-2). All positive women were oriented not to breastfeed their newborns. CONCLUSIONS: This study showed that the virus is present in high prevalence in that population. Further studies covering other segments of the population are necessary to better characterize the presence of HTLV-1/2 in Maranhão and to elicit measures to prevent its spread.

INTRODUCTION: Infection by Neisseria meningitidis, termed as meningococcal disease, can cause meningococcal meningitis and septicemia with or without meningitis. Meningococcal disease is endemic in Brazil and has a high potential to cause large-scale epidemics; therefore, it requires the immediate notification of cases to the Information System for Notifiable Diseases (SINAN) in Brazil. The aim of this study was to describe an epidemiological profile using data from notified and confirmed cases in the State of Minas Gerais, Brazil, from January 2000 to December 2009, obtained from the investigation records of individuals with meningitis registered with SINAN. METHODS: This was a retrospective, population-based study. Descriptive analysis of the data was made using the simple and relative frequencies of the categorical variables in the investigation records. RESULTS: There were 1,688 confirmed patients in Minas Gerais of which 45.5% lived in the Central, North, and Triângulo Mineiro regions. The highest frequencies of cases were in the 1-4-years age group (26.3%), males (54.7%), caucasian (36.4%), and lived in an urban area (80%). In the patients with specified education, 650 (60.9%) patients had secondary education. Serogrouping of meningococci had been performed in 500 (29.6%) patients by age and gender; 285 (57%) belonged to serogroup C, 67 (13.4%) were in the 1-to 4-years age group, and 168 (33.6%) were male. CONCLUSIONS: The epidemiological profiles of patients in the Central, North, and Triângulo Mineiro regions were not significantly different from the profile of patients in Minas Gerais.

Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC), which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

RESUMO - Introdução: Os critérios de adequação (Appropriate Use Criteria - AUC) em Ecocardiografia Transtorácica (ETT) foram publicados com o intuito de permitir o uso racional da ecocardiografia, de influenciar decisões clinicas, prestar cuidados de saúde de elevada qualidade e melhorar o outcome dos pacientes. A relação entre a adequação destes e o seu impacto clinico ainda não se encontra largamente estudada. Objectivo: Neste estudo pretendeu-se avaliar o grau de adesão aos AUC em ETT, em diferentes contextos de atendimento e de acordo com diferentes especialidades, bem como o impacto clínico do exame no outcome do paciente, num hospital público terciário no Reino Unido. Metodologia: 859 ETTs realizados consecutivamente no mês de Janeiro de 2014, foram revistos por forma a avaliar a sua adequação e foram classificados como adequados, incertos ou inadequados de acordo com as guidelines de 2011. De seguida os registos dos pacientes foram revistos com o intuito de avaliar o impacto clinico dos ETTs e foram classificados de acordo com uma das 3 seguintes categorias: (1) alteração ativa dos cuidados – por continuação ou descontinuação dos cuidados como resultado do ETT, (2) continuação dos cuidados – sem continuação ou descontinuação dos cuidados, mas comunicação ao paciente dos resultados do ETT, (3) sem alteração dos cuidados – os cuidados ao paciente já estavam a ser aplicados previamente ao resultado do ETT, causa de sintomas já estabelecida no momento da requisição para exame, exame prévio explicativo dos sintomas e sem indicação aguda para novo ETT, terapêutica não alterada ou inexistência de documentação relativa aos achados ecocardiográficos. Pacientes cujos registos não se encontravam disponíveis foram excluídos (259). Todas as classificações foram avaliadas por uma cardiologista independente, sem relação direta com o estudo. Resultados: A nossa amostra apresentou uma média de idades de 63 ± 17 anos, com uma equilíbrio de géneros. A maioria dos exames foi solicitada em contexto de ambulatório (81,4%), pela Cardiologia (50,3%) e pela Medicina Geral e Familiar (13,4%). Relativamente aos achados ecocardiográficos dos exames, 7,6% demonstraram disfunção sistólica do ventrículo esquerdo moderada a grave, 4,0% revelaram doença valvular grave e 5,1% hipertensão pulmonar significativa. Em relação à adequação dos pedidos para ETTs, 76,5% foram adequados, 7,1% inadequados e 12,6% incertos. Relativamente ao impacto clínico dos ETTs, 42,7% dos exames revelaram uma alteração ativa nos cuidados, 15,6% mostraram uma continuação dos cuidados e 11,5% demonstraram não haver alteração nos cuidados. A idade (P=0,05), o contexto de atendimento (P<0,01) e o pedido realizado pela especialidade medicina geral e familiar (MGF) (P=0,02) foram os preditores mais importantes de uma alteração ativa nos cuidados. Numa perspectiva de prestação de cuidados a uma população mais idosa, o contexto de atendimento, a presença de achados ecocardiográficos significativos e a não alteração dos cuidados apresentam uma relação significativa com a idade. Conclusões: Os dados demonstram que quase 8 em cada 10 ETTs foram considerados adequados e que 4 em cada 10 exames não apresentaram alteração ativa dos cuidados.

The global prevalence of hepatitis B virus is estimated to be 350 million chronic carriers, varying widely from low (<2%, as in Western Europe, North America, New Zealand, Australia, and Japan) to high (>8% as in Africa, Southeast Asia, and China). The overall prevalence in Brazil is about 8%. There are currently 7 genotypic variations, from A to G, and also 4 main surface antigen subtypes: adw, ayw, adr, and ayr. There has been great interest in identifying the geographic distribution and prognosis associated with the various genotypes and subtypes. Although the serologic test is highly sensitive and specific, it does not detect cases of mutant hepatitis B, which is increasingly common worldwide due to resistance and vaccine escape, antiviral therapy, and immunosuppression, among other causes. Alterations in surface, polymerase, X region, core, and precore genes have been described. The main mutations occur in surface and in core/precore genes, also known as occult hepatitis, since its serologic markers of active infection (HBsAg) and viral replication (HBeAg) can be negative. Thus, mutation should be suspected when serologic tests to hepatitis B show control of immunity or replication coincident with worsened clinical status and exclusion of other causes of hepatitis.
