Hemodynamic and physical performance during maximal exercise in patients with an aortic bioprosthetic valve Comparison of stentless versus stented bioprostheses

AbstractOBJECTIVESThe objective of this study was to compare stentless bioprostheses with stented bioprostheses with regard to their hemodynamic behavior during exercise.BACKGROUNDStentless aortic bioprostheses have better hemodynamic performances at rest than stented bioprostheses, but very few comparisons were performed during exercise.METHODSThirty-eight patients with normally functioning stentless (n = 19) or stented (n = 19) bioprostheses were submitted to a maximal ramp upright bicycle exercise test. Valve effective orifice area and mean transvalvular pressure gradient at rest and during peak exercise were successfully measured using Doppler echocardiography in 30 of the 38 patients.RESULTSAt peak exercise, the mean gradient increased significantly less in stentless than in stented bioprostheses (+5 ± 3 vs. +12 ± 8 mm Hg; p = 0.002) despite similar increases in mean flow rates (+137 ± 58 vs. +125 ± 65 ml/s; p = 0.58); valve area also increased but with no significant difference between groups. Despite this hemodynamic difference, exercise capacity was not significantly different, but left ventricular (LV) mass and function were closer to normal in stentless bioprostheses. Overall, there was a strong inverse relation between the mean gradient during peak exercise and the indexed valve area at rest (r = 0.90).CONCLUSIONSHemodynamics during exercise are better in stentless than stented bioprostheses due to the larger resting indexed valve area of stentless bioprostheses. This is associated with beneficial effects with regard to LV mass and function. The relation found between the resting indexed valve area and the gradient during exercise can be used to project the hemodynamic behavior of these bioprostheses at the time of operation. It should thus be useful to select the optimal prosthesis given the patient’s body surface area and level of physical activity

For Good Measure:Advancing Research on Well-Being Metrics Beyond GDP

The 2009 Commission on the Measurement of Economic Performance and Social Progress (“Stiglitz-Sen-Fitoussi” Commission) concluded that we should move away from over-reliance on GDP when assessing a country’s health, towards a broader dashboard of indicators that would reflect concerns such as the distribution of well-being and sustainability in all of its dimensions. This book includes contributions from members of the OECD-hosted High Level Expert Group on the Measurement of Economic Performance and Social Progress, the successor of the Stiglitz-Sen-Fitoussi Commission, and their co-authors on the latest research in this field. These contributions look at key issues raised by the 2009 Commission that deserved more attention, such as how to better include the environment and sustainability in our measurement system, and how to improve the measurement of different types of inequalities, of economic insecurity, of subjective well-being and of trust. A companion volume Beyond GDP: Measuring What Counts for Economic and Social Performance presents an overview by the co-chairs of the High Level Expert Group, Joseph E. Stiglitz, Jean-Paul Fitoussi and Martine Durand of the progress accomplished since the 2009 report, of the work conducted by the Group over the past five years, and of what still needs to be done

Beyond GDP:Measuring What Counts for Economic and Social Performance

Metrics matter for policy and policy matters for well-being. In this report, the co-chairs of the OECD-hosted High Level Expert Group on the Measurement of Economic Performance and Social Progress, Joseph E. Stiglitz, Jean-Paul Fitoussi and Martine Durand, show how over-reliance on GDP as the yardstick of economic performance misled policy makers who did not see the 2008 crisis coming. When the crisis did hit, concentrating on the wrong indicators meant that governments made inadequate policy choices, with severe and long-lasting consequences for many people. While GDP is the most well-known, and most powerful economic indicator, it can’t tell us everything we need to know about the health of countries and societies. In fact, it can’t even tell us everything we need to know about economic performance. We need to develop dashboards of indicators that reveal who is benefitting from growth, whether that growth is environmentally sustainable, how people feel about their lives, what factors contribute to an individual’s or a country’s success. This book looks at progress made over the past 10 years in collecting well-being data, and in using them to inform policies. An accompanying volume, For Good Measure: Advancing Research on Well-being Metrics Beyond GDP, presents the latest findings from leading economists and statisticians on selected issues within the broader agenda on defining and measuring well-being

West Nile Virus in Horses, sub-Saharan Africa

To evaluate the presence and extension of West Nile virus where French soldiers are stationed in Africa, specific antibody prevalence was determined by using ELISA and Western blot. Among 245 horses living in close proximity to the soldiers, seroprevalence was particularly high in Chad (97%) and Senegal (92%)

Planeamiento estratégico del sistema educativo universitario privado de la región Arequipa

El plan estratégico elaborado para el sistema educativo universitario privado en la región Arequipa, busca priorizar las estrategias más apropiadas para el sector sobre la base de análisis internos y externos, combinación de fortalezas, debilidades, oportunidades, y amenazas, formulación de estrategias alineadas a la visión, y filtrado de cada una de las estrategias por nivel de atractividad. Luego de haber finalizado esta etapa de formulación, se ha procedido a la etapa de implementación que consiste en establecer los objetivos a corto plazo, asignar recursos, definir políticas, y proponer una nueva estructura organizacional. Finalmente, en la etapa de evaluación estratégica se han formulado los indicadores para controlar el nivel de avance en el tablero de control del Balance Scored Card. Es necesario señalar que a la fecha los diversos rankings a nivel mundial, destacan más las universidades privadas internacionales; asimismo, a nivel nacional también se presenta un notorio liderazgo de las universidades de la capital. Arequipa, como segunda ciudad del país, la cual se encuentra ubicada estratégicamente en la región sur del Perú y tiene todas las condiciones para poder crecer tanto en número de alumnos como en calidad educativa, mediante el aprovechamiento de su infraestructura, podrá lograr los objetivos que se proponga. El reto propuesto es lograr que para el año 2025, el Sistema Universitario Privado de Arequipa sea el mejor sistema universitario privado del Perú.The strategic plan developed for the Educational System Private University in Arequipa region, searches based on internal and external analyzes, the combination of strengths, weaknesses, opportunities and threats, to formulate strategies aligned to the vision, and filtering each strategies by level of attractiveness, have the necessary support to prioritize the most appropriate strategies for the sector. Having just completed this stage of development, we have proceeded to the implementation stage which is to establish short-term goals, allocate resources, define policies and propose a new organizational structure. Finally in the strategic evaluation stage are formulated, indicators to monitor the level of progress in the control board Balance Scored Card. It should be noted that currently the global ranking, private universities are more prominent international nationally is also true that it has a notorious leader of the university in the capital. Arequipa, as second city, which is strategically located in the southern region of Peru and has all the conditions to grow both in number of students and quality education through the use of their existing infrastructure, can achieve the objectives proposed. The proposed challenge is to ensure that by 2025, the Private University System of Arequipa is the best private university system in Peru.Tesi
