Uma Luta Justa contra a Resistência Antimicrobiana

BRIGHTON – As drogas antimicrobianas existentes estão se tornando ineficazes. Se as tendências atuais continuarem, podemos acabar revivendo condições anteriores à descoberta dos antibióticos, quando as doenças infecciosas eram grandes assassinas.

Será difícil atender ao desafio de micróbios resistentes aos medicamentos. Exigirá não só grandes investimentos em pesquisa e desenvolvimento de novas drogas antimicrobianas, mas também um sistema para controlar e restringir novos tratamentos, a fim de preservar a sua eficácia. Como com a resposta às alterações climáticas, uma estratégia eficaz exigirá coordenação internacional. Em particular, as necessidades das empresas farmacêuticas devem ser conciliadas com as dos contribuintes do governo e a população pobre mundial.

Na verdade, engajar a população pobre será crucial para qualquer esforço. Países de baixa e média renda são uma importante fonte de organismos resistentes aos medicamentos. Os aglomerados habitacionais, a falta de saneamento básico e o sistema imunológico comprometido, seja devido à desnutrição ou infecções crônicas como o HIV, propiciam um terreno fértil para o contágio.  Frequentemente, os antibióticos são usados de maneira errada ou são de baixa qualidade, propiciando às bactérias a oportunidade de desenvolver resistência. Grandes volumes de antibióticos também são utilizados na pecuária. Enquanto isso, a infraestrutura de transporte melhorou muito – entre zonas rurais e urbanas e entre países – o que significa que genes resistentes rapidamente tornam-se parte de um pool global.

    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.
