El uso sabio de los antibióticos

LONDRES – Para resolver el problema de la resistencia a los antimicrobianos, el mundo necesita no sólo nuevos medicamentos, sino que también un nuevo comportamiento – es decir, es necesario que  todos nosotros, los siete mil millones de personas que lo habitamos, cambiemos de comportamiento. Debido al mal uso y abuso de los antibióticos, infecciones comunes, tales como la neumonía y la tuberculosis, se hacen cada vez más resistentes a los tratamientos existentes; en algunos casos, se han hecho completamente inmunes.

La amenaza es de escala mundial. De acuerdo al proyecto de Estudio sobre resistencia a los antimicrobianos  que yo presido, las infecciones resistentes a los fármacos matan al menos a 700.000 personas cada año. Hasta el año 2050, si no se hace nada para abordar el problema,  unos diez millones de personas al año podrían morir a causa de enfermedades que alguna vez sí fueron tratables.

El desarrollo de nuevos medicamentos es un abordaje importante dentro de una respuesta coordinada para combatir la resistencia a los antimicrobianos. Sin embargo, no va a ser suficiente. También debemos reducir nuestra demanda de antibióticos y debemos entender que a veces pueden causar más daño que beneficio. Según un cálculo aproximado, casi la mitad de todas las recetas de antibióticos en Estados Unidos son inadecuadas o innecesarias. Por lo tanto, el pronunciado ascenso en la resistencia a los antibióticos no es nada sorprendente.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
