Utiliser les antibiotiques judicieusement

LONDRES – Pour résoudre le problème de résistance aux antimicrobiens, le monde a besoin non seulement de nouveaux médicaments, mais également de nouveaux comportements – de la part des sept milliards d’entre nous. En raison de la mauvaise utilisation et de la surutilisation d’antibiotiques, des infections courantes comme la pneumonie et la tuberculose deviennent de plus en plus résistantes aux traitements existants ; et dans certains cas, elles sont devenues complètement immunisées aux traitements.

La menace est d’échelle mondiale. Selon la Commission d’examen sur la résistance aux antimicrobiens, que je préside, les infections qui résistent aux médicaments causent au moins 700 000 décès par an. D’ici 2050, si rien n’est fait pour s’attaquer au problème, près de dix millions de personnes par an pourraient mourir de maladies qui étaient auparavant traitables.

La mise au point de nouveaux médicaments est une démarche importante dans une réplique coordonnée pour combattre la résistance aux antimicrobiens. Mais cela ne suffira pas. Nous avons besoin de réduire notre demande d’antibiotiques et de reconnaître qu’ils peuvent parfois faire plus de mal que de bien. Selon une estimation, presque la moitié de toutes les prescriptions d’antibiotiques aux États-Unis sont inappropriées ou inutiles. L’essor de la résistance aux antibiotiques n’est donc pas vraiment surprenant.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
