Incident hypertension among pre-hypertensive adolescents: Evaluation of pre-hypertension as an independent risk factor among secondary school students in the Houston area

Cardiovascular disease has been the leading cause of death in the United States for over fifty years. While multiple risk factors for cardiovascular disease have been identified, hypertension is one of the most commonly recognized and treatable. Recent studies indicate that the prevalence of hypertension among children and adolescents is between 3-5%, much higher than originally estimated and likely rising due to the epidemic of obesity in the U.S. In 2004, the National High Blood Pressure Education Program Working Group on High Blood Pressure in Children and Adolescents published new guidelines for the diagnosis and treatment of hypertension in this population. Included in these recommendations was the creation of a new diagnosis, pre-hypertension, aimed at identifying children at-risk for hypertension to provide early lifestyle interventions in an effort to prevent its ultimate development. In order to determine the risk associated with pre-hypertension for the development of incident HTN, a secondary analysis of a repeated cross-sectional study measuring blood pressure in Houston area adolescents from 2000 to 2007 was performed. Of 1006 students participating in the blood pressure screening on more than one occasion not diagnosed with hypertension at initial encounter, eleven were later found to have hypertension providing an overall incident rate of 0.5% per year. Incidence rates were higher among overweight adolescents–1.9% per year [IRR 8.6 (1.97, 51.63)]; students “at-risk for hypertension” (pre-hypertensive or initial blood pressure in the hypertensive range but falling on subsequent measures)–1.4% per year [IRR 4.77 (1.21, 19.78)]; and those with blood pressure ≥90th percentile on three occasions–6.6% per year [IRR 21.87 (3.40, 112.40)]. Students with pre-hypertension as currently defined by the Task Force did have an increased rate of hypertension (1.1% per year) but it did not reach statistical significance [IRR 2.44 (0.42, 10.18)]. Further research is needed to determine the morbidity and mortality associated with pre-hypertension in this age group as well as the effectiveness of various interventions for preventing the development of hypertensive disease among these at-risk individuals. ^

Learning by Not Doing: Subsidy Disciplines in Services Trade

This paper explores the hitherto futile quest for developing disciplines on the trade- and investment-distorting effects of services subsidies. It sheds light on the multiplicity of factors that have weighed on the conduct of negotiations on subsidy disciplines in a services trade context at both the global and preferential levels, and advances a few thoughts on what the future may hold for the adoption of such disciplines. The analysis suggests that it is rather unlikely that WTO Members will any time soon reach a consensus on the matter of subsidy disciplines for services beyond those that currently (and timidly) obtain in the GATS and in many preferential trade agreements. The main reason behind such a conclusion stems from a marked rise in the value of preserving policy space in a trading environment characterized by considerably greater global market contestability than two decades ago.

Assesing the usefulness of the ACM/IEEE-CS Computing Curricula for the design of Computer-Related Engineering Curricula, an experience in Telematics

This paper presents the rationale to build up a Telematics Engineering curriculum. Telematics is a strongly computing oriented area; then, the authors have initially intended to apply the common requirements described in the computing curricula elaborated by the ACM/EEEE-CS Joint Curriculum Task Force. This experience has revealed some problematic aspects in the ACM/IEEE-CS proposal. From the analysis of these problems, a model to guide the selection and specially the approach of the Telematics curriculum contents is proposed. This model can be easily generalized to other strongly computing oriented curricula, whose number is growing everyday

Desarrollo de un portal de monitorización y análisis de estadísticas de sesiones de comunicación en tiempo real

En este Trabajo de Fin de Grado se va a explicar el procedimiento seguido a la hora de estudiar, diseñar y desarrollar Ackuaria, un portal de monitorización y análisis de estadísticas de comunicaciones en tiempo real. Después, se mostrarán los resultados obtenidos y la interfaz gráfica desarrollada para una mejor experiencia de usuario. Ackuaria se apoyará en el uso de Licode, un proyecto de código libre desarrollado en la Universidad Politécnica de Madrid, más concretamente en el Grupo de Internet de Nueva Generación de la Escuela Técnica Superior de Ingenieros de Telecomunicación. Licode ofrece la posibilidad de crear un servicio de streaming y videoconferencia en la propia infraestructura del usuario. Está diseñado para ser totalmente escalable y su uso está orientado principalmente al Cloud, aunque es perfectamente utilizable en una infraestructura física. Licode a su vez se basa en WebRTC, un protocolo desarrollado por la W3C (World Wide Web Consortium) y el IETF (Internet Engineering Task Force) pensado para poder transmitir y recibir flujos de audio, video y datos a través del navegador. No necesita ninguna instalación adicional, por lo que establecer una sesión de videoconferencia Peer-to-Peer es realmente sencillo. Con Licode se usa una MCU (Multipoint Control Unit) para evitar que todas las conexiones entre los usuarios sean Peer-To-Peer. Actúa como un cliente WebRTC más por el que pasan todos los flujos, que se encarga de multiplexar y redirigir donde sea necesario. De esta forma se ahorra ancho de banda y recursos del dispositivo de una forma muy significativa. Existe la creciente necesidad de los usuarios de Licode y de cualquier servicio de videoconferencia en general de poder gestionar su infraestructura a partir de datos y estadísticas fiables. Sus objetivos son muy variados: desde estudiar el comportamiento de WebRTC en distintos escenarios hasta monitorizar el uso de los usuarios para poder contabilizar después el tiempo publicado por cada uno. En todos los casos era común la necesidad de disponer de una herramienta que permitiese conocer en todo momento qué está pasando en el servicio de Licode, así como de almacenar toda la información para poder ser analizada posteriormente. Para conseguir desarrollar Ackuaria se ha realizado un estudio de las comunicaciones en tiempo real con el objetivo de determinar qué parámetros era indispensable y útil monitorizar. A partir de este estudio se ha actualizado la arquitectura de Licode para que obtuviese todos los datos necesarios y los enviase de forma que pudiesen ser recogidos por Ackuaria. El portal de monitorización entonces tratará esa información y la mostrará de forma clara y ordenada, además de proporcionar una API REST al usuario.

ANALISANDO A RELAÇÃO DOS VOLUMES DE EXPORTAÇÃO E DE IMPORTAÇÃO, PIB, TAXAS DE CÂMBIO E INFLAÇÃO NO PERÍODO DE 2004 A 2014.

Esta dissertação visa deslumbrar uma análise macroeconômica do Brasil, especialmente no que se refere à relação dos índices mensais dos volumes das exportações e das importações com os volumes mensais do PIB, da Taxa SELIC e as Taxas de Câmbio, conforme dados coletados no período de janeiro de 2004 a dezembro de 2014, através de pesquisa literária referente aos históricos sobre cada conceito envolvido no âmbito da macroeconomia das varáveis estudadas. Foi realizado um estudo de caso embasado em dados de sites governamentais, no período delimitado, empregando-se o método de regressão linear, com base na Teoria da correlação de Pearson, demonstrando os resultados obtidos no período do estudo para as varáveis estudadas. Desta maneira, conseguiu-se estudar e analisar como as variáveis dependentes (resposta): volume das exportações e volume das importações estão relacionadas com as varáveis independentes (explicativas): PIB, Taxa Selic e taxa de Câmbio. Os resultados apurados no presente estudo permitem identificar que existe correlação moderada e negativa, quando analisadas a Taxa Selic e a Taxa de Câmbio com os volumes das exportações e das importações, enquanto o PIB apresenta correlação forte e positiva na análise com os volumes das exportações e das importações

Utilizing Evidence-Based Psychology Practice in the University of Denver's Professional Psychology Center: A Proposal

As acceptance of the Evidence-based Psychology Practice (EBPP) model continues to grow (Pagoto, Spring, Coups, Mulvaney, Coutu, & Ozakinci, 2007), it seems pertinent to explore how this model can be applied in different settings. This topic is timely as practitioners in the field are being held ever more accountable for the efficacy of the treatments they employ (Pagoto et al., 2007). Increased scrutiny has resulted in a need to integrate research into practice in order to ensure continued relevance in the ever-changing realm of American health care (Luebbe, Radcliffe, Callands, Green & Thorn, 2007; Collins, Leffingwell & Belar, 2007; Chwalisz, 2003). This paper explores how the requirements set forth by the American Psychological Association Presidential Task Force on Evidence-Based Practice (2006) can be implemented at the University of Denver's (DU) Professional Psychology Center (PPC), a training clinic for students enrolled in the Psy.D. program at DU's Graduate School of Professional Psychology (GSPP). In doing so, the methods employed by Collins et al. (2007) at Oklahoma State University (OSU) are used as a template and modified to accommodate differences between these two institutions.

Avaliação dos níveis de radiação ambiental no laboratório de tomografia por emissão de pósitrons acoplada a tomografia computadorizada, microPET/CT

O sistema microPET/CT é um importante equipamento utilizado nas pesquisas de imagem diagnóstica em pequenos animais. O radiofármaco mais usado nesta tecnologia é o fluordeoxiglicose marcado com flúor-18. Este estudo tem como objetivo efetuar o controle radiológico no laboratório de pesquisa microPET/CT do Centro de Radiofarmácia do IPEN-CNEN/SP, de forma a satisfazer tanto as normas nacionais como as recomendações internacionais. O laboratório está classificado pela equipe de radioproteção da instalação como área supervisionada, nas quais embora não seja obrigatória a adoção de medidas específicas de proteção e segurança, devem ser submetidas reavaliações regulares das condições do ambiente de trabalho. Visando assegurar a proteção radiológica dos trabalhadores diretamente envolvidos no manuseio do equipamento, realizou-se o monitoramento do local de trabalho e a avaliação do controle de dose individual. Inicialmente foi feito o monitoramento pré-operacional, isto é, o levantamento radiométrico no laboratório. Além disso, mediu-se nível de radiação externa nas instalações do laboratório e suas adjacências, por meio da colocação de nove dosímetros termoluminescentes (TL) de CaSO4:Dy, em locais previamente selecionados. Os indivíduos ocupacionalmente expostos foram avaliados mensalmente por meio do uso de dosímetros TL posicionados no tórax e por medidas de corpo inteiro, tomadas a cada seis meses. O período do estudo foi de dois anos, com início em abril de 2014. Para o controle do microPET/CT realizou-se testes de desempenho de acordo com o protocolo padrão do equipamento e em conformidade com a norma desenvolvida pela força tarefa para estudos com PET em animais Animal PET Standard Task Force. O presente estudo permitiu demonstrar que os níveis de radiação das áreas (estimativas de dose ambiente e dose efetiva), assim como a blindagem do equipamento estão adequados de acordo com os limites da exposição ocupacional. Ressalta-se a importância de se seguir rigorosamente os princípios de radioproteção, já que se trata de pesquisas com fontes radioativas não seladas.

The future of the area of freedom, security and justice. Addressing mobility, protection and effectiveness in the long run. EPC Discussion Paper, 23 January 2014

With the Stockholm Programme coming to an end in 2014, the “Brussels Community” is increasing agitated with a recurring question: what will replace the Stockholm Programme? Paradoxically, this uncertainty is fuelled by the existence of a new and clear Treaty provision – Article 68 TFEU – which states “The European Council shall define the strategic guidelines for legislative and operational planning within the area of freedom, security and justice”. Clear in its wording, this provision may lead to different understandings and unclear implications in practice. In order to provide more clarity, the European Policy Centre (EPC) set up a Task Force to reflect on the impact of this provision and more generally the future of the area of freedom, security and justice after 2014. Results of this process are reflected in this discussion paper which addresses the process and content regarding the definition of future strategic guidelines.

Russian army justifies its reforms. OSW Commentary No. 109, 2013-06-25

The Armed Forces of the Russian Federation have been more active than usual since mid- -February this year, holding a number of previously unannounced military exercises aimed at testing combat readiness. They have also maintained, for many months, a Russian warship task force in the Mediterranean in connection with the civil war in Syria. Those activities stand out of the usual training routine of the Russian army. They have no precedent in Russia’s recent history in terms of the size of the forces involved, the measures employed, the territorial span, the number of exercises, or the scheduling and mode of carrying out the drills. The last combat-readiness tests on this scale were carried out by the Soviet army in the 1980s. The intensity of the Russian Navy’s activities in the Mediterranean and the military means engaged are comparable, in due proportion, with the activities of the Soviet fleet during the Vietnam war. The Russian leadership, including president Vladimir Putin, has been directly following the recent activities of the Russian Armed Forces and their evolution.

Coltan from Central Africa, International Trade and Implications for Any Certification. Bruges European Economic Policy (BEEP) 23/2012

The exploitation of coltan in Central Africa can be considered a case of conflict minerals due to its nature. Many international organizations and bodies, national governments and private sector organizations seek to address this conflict, in particular via transparency, certification and accountability along the material supply chain. This paper analyses the international trade dimension of coltan and gives evidence on the dimension of illicit trade of coltan. The authors start from the hypothesis that illicit trade of coltan sooner or later will enter the market and will be reflected in the statistics. The paper is structured in the following manner: first, a short section gives a profile of coltan production and markets; second, an overview of the mining situation in the Democratic Republic of Congo (DRC) and related actors. The third section addresses mechanisms, actors and measurement issues involved in the international trade of coltan. The final part draws lessons for certification and conflict analysis and offers some guidance for future research. The paper identifies two main possible gateways to trace illegal trade in coltan: the neighbouring countries, especially Rwanda, and the importing countries for downstream production, in particular China. Our estimation is that the value of such illicit trade comes close to $ 27 million annually (2009), roughly one fifth of the world market volume for tantalum production. With regard to any certification the paper concludes that this will become challenging for business and policy: (a) Central Africa currently is the largest supplier of coltan on the world market, many actors profit from the current situation and possess abilities to hide responsibility; (b) China will need to accept more responsibility, a first step would be the acceptance of the OECD guidelines on due diligence; (c) better regional governance in Central Africa comprises of resource taxation, a resource fund and fiscal coordination. An international task force may provide more robust data, however more research will also be needed.

Electrocardiographic features of disease progression in arrhythmogenic right ventricular cardiomyopathy/dysplasia.

BACKGROUND Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is considered a progressive cardiomyopathy. However, data on the clinical features of disease progression are limited. The aim of this study was to assess 12-lead surface electrocardiographic (ECG) changes during long-term follow-up, and to compare these findings with echocardiographic data in our large cohort of patients with ARVC/D. METHODS Baseline and follow-up ECGs of 111 patients from three tertiary care centers in Switzerland were systematically analyzed with digital calipers by two blinded observers, and correlated with findings from transthoracic echocardiography. RESULTS The median follow-up was 4 years (IQR 1.9-9.2 years). ECG progression was significant for epsilon waves (baseline 14% vs. follow-up 31%, p = 0.01) and QRS duration (111 ms vs. 114 ms, p = 0.04). Six patients with repolarization abnormalities according to the 2010 Task Force Criteria at baseline did not display these criteria at follow-up, whereas in all patients with epsilon waves at baseline these depolarization abnormalities also remained at follow-up. T wave inversions in inferior leads were common (36% of patients at baseline), and were significantly associated with major repolarization abnormalities (p = 0.02), extensive echocardiographic right ventricular involvement (p = 0.04), T wave inversions in lateral precordial leads (p = 0.05), and definite ARVC/D (p = 0.05). CONCLUSIONS Our data supports the concept that ARVC/D is generally progressive, which can be detected by 12-lead surface ECG. Repolarization abnormalities may disappear during the course of the disease. Furthermore, the presence of T wave inversions in inferior leads is common in ARVC/D.
