Artesunate + amodiaquine versus artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria in the Colombian Pacific region: a noninferiority trial

INTRODUCTION: In Colombia, there are no published studies for the treatment of uncomplicated Plasmodium falciparum malaria comparing artemisinin combination therapies. Hence, it is intended to demonstrate the non-inferior efficacy/safety profiles of artesunate + amodiaquine versus artemether-lumefantrine treatments. METHODS: A randomized, controlled, open-label, noninferiority (Δ≤5%) clinical trial was performed in adults with uncomplicated P. falciparum malaria using the 28‑day World Health Organization validated design/definitions. Patients were randomized 1:1 to either oral artesunate + amodiaquine or artemether-lumefantrine. The primary efficacy endpoint: adequate clinical and parasitological response; secondary endpoints: - treatment failures defined per the World Health Organization. Safety: assessed through adverse events. RESULTS: A total of 105 patients was included in each group: zero censored observations. Mean (95%CI - Confidence interval) adequate clinical and parasitological response rates: 100% for artesunate + amodiaquine and 99% for artemether-lumefantrine; the noninferiority criteria was met (Δ=1.7%). There was one late parasitological therapeutic failure (1%; artemether-lumefantrine group), typified by polymerase chain reaction as the MAD20 MSP1 allele. The fever clearance time (artesunate + amodiaquine group) was significantly shorter (p=0.002). Respectively, abdominal pain for artesunate + amodiaquine and artemether-lumefantrine was 1.9% and 3.8% at baseline (p=0.68) and 1% and 13.3% after treatment (p<0.001). CONCLUSIONS: Uncomplicated P. falciparum malaria treatment with artesunate + amodiaquine is noninferior to the artemether-lumefantrine standard treatment. The efficacy/safety profiles grant further studies in this and similar populations.

Financial depth, stock markets and economic growth in the EU-15 countries

The aim of this paper is to assess the impact of financial depth on economic growth in the EU-15 countries from 1970 until 2012, using the two-step System GMM estimator. Even though it might be expected a positive impact, the results show it is negative and sometimes even negative and statistically significant. Among the reasons presented for this, the existence of banking crises seems to better explain these results. In tranquil periods, financial deepening appears to have a positive impact, whereas in banking crises it is persistently negative and statistically significant. Also, after an assessment of the impact of stock markets on economic growth, it appears that more developed countries in the EU-15 have an economy more reliant on this segment of the financial system rather than in bank intermediation.

UK Mental health professionals volunteering in LMIC-benefits to UK and host countries

RESUMO: O Royal College of Psychiatrists tem um programa de voluntariado internacional desde 2005. O interesse no Reino Unido tem crescido nos últimos 15 anos com muitos projetos novos. Os benefícios para vários países têm sido reconhecidos. O que está menos claro são os benefícios da experiência para o Reino Unido e do programa de voluntariado do Royal College of Psychiatrists. O objectivo desta dissertação é explorar os benefícios do voluntariado para o Sistema Nacional de Saúde focando principalmente, mas não exclusivamente, o programa de voluntariado do Royal College of Psychiatrists. Nesta dissertação abordamos primeiro o contexto antes de discutirmos dois grandes estudos de psiquiatras e hospitais do Sistema Nacional de Saúde no Reino Unido. Incluimos no estudo todos os psiquiatras registados como Voluntários no Royal College of Psychiatrists e o Grupo de Interesse Especial associado. Foi ainda possível incluir os Diretores Médicos de todos os hospitais do Reino Unido. Os estudos foram desenhados para analisar as opiniões dos Voluntários do Reino Unido sobre os benefícios para os países recetores de baixo e médio rendimento e para o Reino Unido. Todos os 60 hospitais do Sistema Nacional de Saúde foram incluí dos para analisar a opinião sobre Voluntariado. As limitações dos estudos foram a baixa taxa de resposta, mas esta foi comparável a outros estudos do College. É provável haver um enviezamento de resposta e favorecimento dos que estão envolvidos no Voluntariado. Os resultados mostraram um interesse forte no voluntariado e benefícios no Sistema Nacional de Saúde, nas. áreas de liderança, transculturalismo, gestão e recursos e capacidades pessoais. Os hospitais do Sistema Nacional de Saúde valorizaram o voluntariado e, em contrapartida, o valor acrescido para competências profissionais. Os obstáculos contra o Voluntariado a nível individual e dos hospitais foram maioritariamente de natureza prática, tais como obter dispensa do trabalho, substituição no trabalho e custos. As implicações destes estudos são que o programa de voluntariado do College precisa de ser fortalecido. Para assegurar que este trabalho continua é necessário existir uma sensibilização nacional e maior responsabilização sobre os benefícios para o Reino Unido e a nível global. -------------------------- ABSTRACT: The Royal College of Psychiatrists has had an international volunteering programme since 2005. The interest in UK has grown over the past 15 years with many new projects. The benefits in various countries has been acknowledged. What has been less clear are the benefits of the experience back in the UK and of the Royal College of Psychiatrists Volunteer Scheme. The aim of this dissertation is to explore the benefit of volunteering to the NHS focusing mainly, but not exclusively on the Royal College of Psychiatrists Volunteering scheme. In this dissertation we first look at background information before discussing two large surveys of Psychiatrists and NHS Trusts in UK. We surveyed all those registered as Volunteers at the Royal College of Psychiatrists and the associated Special Interest Group. We also were able to survey the Medical Directors of all UK Trusts. The Surveys were designed to assess views of UK Volunteers of benefits to hosts in LMIC and back in UK. All 60 NHS Trusts were surveyed to assess the view of Volunteering. Limitation of the surveys were the low response rate but this was comparable to other College surveys. There is likely to be a bias in response and favour those who are engaged in the Volunteering agenda. Results showed a strong interest in volunteering and perceived benefits in NHS. These areas included leadership, transcultural, resource management and personal skills. NHS trusts valued volunteering and added value to professional competencies on return. Obstacles to Volunteering at individual and Trust level were mainly practical issues such as getting time off, cover and costs. Implications of these surveys are that the College volunteering scheme needs strengthening. There needs to be a National advocacy to ensure that this work continues and greater accountability as to benefits in UK and globally.

Systematics, functional morphology and distribution of a bivalve (Apachecorbula muriatica gen. et sp. nov.) from the rim of the ‘Valdivia Deep’ brine pool in the Red Sea

The deep brine pools of the Red Sea comprise extreme, inhospitable habitats yet house microbial communities that potentially may fuel adjacent fauna. We here describe a novel bivalve from a deep-sea (1525 m) brine pool in the Red Sea, where conditions of high salinity, lowered pH, partial anoxia and high temperatures are prevalent. Remotely operated vehicle (ROV) footage showed that the bivalves were present in a narrow (20 cm) band along the rim of the brine pool, suggesting that it is not only tolerant of such extreme conditions but is also limited to them. The bivalve is a member of the Corbulidae and named Apachecorbula muriatica gen. et sp. nov. The shell is atypical of the family in being modioliform and thin. The semi-infaunal habit is seen in ROV images and reflected in the anatomy by the lack of siphons. The ctenidia are large and typical of a suspension feeding bivalve, but the absence of guard cilia and the greatly reduced labial palps suggest that it is non-selective as a response to low food availability. It is proposed that the low body mass observed is a consequence of the extreme habitat and low food availability. It is postulated that the observed morphology of Apachecorbula is a result of paedomorphosis driven by the effects of the extreme environment on growth but is in part mitigated by the absence of high predation pressures.

Global warming in Amazonia: impacts and Mitigation

Global warming has potentially catastrophic impacts in Amazonia, while at the same time maintenance of the Amazon forest offers one of the most valuable and cost-effective options for mitigating climate change. We know that the El Niño phenomenon, caused by temperature oscillations of surface water in the Pacific, has serious impacts in Amazonia, causing droughts and forest fires (as in 1997-1998). Temperature oscillations in the Atlantic also provoke severe droughts (as in 2005). We also know that Amazonian trees die both from fires and from water stress under hot, dry conditions. In addition, water recycled through the forest provides rainfall that maintains climatic conditions appropriate for tropical forest, especially in the dry season. What we need to know quickly, through intensified research, includes progress in representing El Niño and the Atlantic oscillations in climatic models, representation of biotic feedbacks in models used for decision-making about global warming, and narrowing the range of estimating climate sensitivity to reduce uncertainty about the probability of very severe impacts. Items that need to be negotiated include the definition of "dangerous" climate change, with the corresponding maximum levels of greenhouse gases in the atmosphere. Mitigation of global warming must include maintaining the Amazon forest, which has benefits for combating global warming from two separate roles: cutting the flow the emissions of carbon each year from the rapid pace of deforestation, and avoiding emission of the stock of carbon in the remaining forest that can be released by various ways, including climate change itself. Barriers to rewarding forest maintenance include the need for financial rewards for both of these roles. Other needs are for continued reduction of uncertainty regarding emissions and deforestation processes, as well as agreement on the basis of carbon accounting. As one of the countries most subject to impacts of climate change, Brazil must assume the leadership in fighting global warming.

VET: a strategic approach for economic, organisational and personal development in EU countries

Vocational Education and Training (VET) is a continuous long-term process of economic, organisational and personal development. It envisions the construction of dynamic skills to improve performance, productivity and organisational, personal and social development. This article focuses on generating skills. It frames training as a process of work-linked training and as a primary source for generating skills whilst seeking to boost creativity. It sheds light upon the discussion pertaining to learning transfer as a necessary condition to structure performance and competitiveness. It highlights the Learning Transfer System Inventory (LTSI), because it allows to measure the effectiveness of training and it identifies the organisations' weaknesses. The data used were collected from the Eurostat Database.

Prevalência da doença arterial coronariana em diabéticos tipo 1 candidatos a transplante duplo (rim e pâncreas)

OBJETIVO: Avaliar a prevalência da doença arterial coronariana (DAC) em população de pacientes diabéticos tipo 1, nefropatas, em programa de diálise e candidatos a transplante duplo (rim e pâncreas). MÉTODOS: De janeiro/2000 a julho/2002, foram submetidos a cinecoronariografia, como protocolo de avaliação para transplante duplo, 58 pacientes diabéticos tipo 1. Doença arterial coronariana foi definida como qualquer irregularidade nas artérias coronárias, e classificada, de acordo com a grau de estenose luminal, em leve (<30%), moderada (>30 a 70%) e grave (>70%). RESULTADOS: A idade dos pacientes foi 34 ± 12 anos, sendo que 32 (55%) eram homens. Nenhum paciente tinha história de angina ou infarto agudo do miocárdio. Os principais fatores de risco para a doença foram hipertensão arterial sistêmica em 93%, dislipidemia em 38%, historia familiar em 25% e tabagismo 20%. O tempo médio de duração do diabetes foi 20,8 ± 9 anos, o tempo de diálise de 26 ± 9 meses. A coronariografia revelou doença arterial coronariana em 42 (72%) pacientes, sendo 20 (34%) discreta, 9 (16%) moderada e 13 (22%) grave. CONCLUSÃO: Pacientes diabéticos tipo 1 em programa de diálise e candidatos a transplante duplo têm elevada prevalência de doença arterial coronariana, tornando-se marcante a observação de que esses pacientes não apresentavam sintomas da doença.

Evolução clínica pós-stent coronariano em pacientes submetidos a transplante de rim

OBJETIVO: Avaliar a evolução clínica de pacientes submetidos a transplante de rim, portadores de doença arterial coronariana, que foram tratados com implante de stent coronariano (ATC-ST). MÉTODOS: Entre julho de 1998 e novembro de 2004, foram realizados, no total, 3.334 transplantes de rim em nossa Instituição (Hospital do Rim e Hipertensão). Desse total, 33 pacientes previamente submetidos a transplante de rim fizeram ATC-ST para o tratamento de 62 estenoses graves em 54 artérias coronárias, nos quais foi realizada análise retrospectiva. O registro dos eventos clínicos foi feito por meio de análise do prontuário médico, consulta médica e ligações telefônicas. RESULTADOS: No seguimento clínico de 30 meses, após a ATC-ST, observou-se que 67% dos pacientes permaneceram assintomáticos, 18% dos pacientes apresentaram quadro de angina estável, 6% apresentaram síndrome coronariana aguda sem supra de ST e 3% apresentaram síndrome coronariana aguda com supra de ST. Não houve pacientes com acidente vascular cerebral, insuficiência cardíaca congestiva ou morte cardíaca. Houve três mortes não-cardíacas. Foi observado índice de reestenose de 9%, que é comparável ao dos estudos de stent farmacológico. CONCLUSÃO: Concluímos que pacientes submetidos a transplante de rim que desenvolveram doença arterial coronariana e que foram tratados com stent coronariano tiveram baixo porcentual de reestenose clínica, provavelmente relacionado ao regime de imunossupressão administrado para evitar rejeição renal.
