L’Uso Accorto degli Antibiotici

LONDRA – Per risolvere il problema della resistenza agli antibiotici, il mondo non ha solo bisogno di nuovi farmaci, ma anche di nuovi comportamenti – da parte di noi tutti, i sette miliardi di persone che abitiamo la terra. A causa del cattivo uso e dell’abuso di antibiotici, infezioni comuni come polmonite e tubercolosi stanno diventando sempre più resistenti agli attuali trattamenti; in alcuni casi, sono diventate completamente immuni.

La minaccia è globale. Secondo la Review on Antimicrobial Resistance, rivista da me diretta, le infezioni resistenti ai farmaci uccidono almeno 700.000 persone ogni anno. Entro il 2050, se non si fa nulla per affrontare il problema, potrebbero morire una decina di milioni di persone all’anno a causa di malattie già curabili.

Lo sviluppo di nuovi farmaci costituisce un percorso importante nell’ambito di una strategia coordinata per combattere la resistenza antimicrobica. Ma ciò non sarà sufficiente. Sarebbe anche necessario ridurre la nostra richiesta di antibiotici e capire che a volte possono fare più male che bene. Secondo una stima, negli Stati Uniti quasi una prescrizione su due per antibiotici è inappropriata o non necessaria. Dunque non è sorprendente il forte aumento della resistenza agli antibiotici.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
