...Still, Fauci acknowledges that the sheer size of Kitahata's study gives its findings some weight. She presented the preliminary data to a government panel on HIV-treatment guidelines in February, and the results have since gotten HIV experts talking about whether waiting to begin treatment until the current threshold of 350 cells is reached is too late to improve HIV patients' survival...
...what is cost-effective and what is cost-ineffective. That is the "How much is life worth?" question. And there is no real empirical research to guide you. We have looked at what other government departments do. Our Department of Transport, for instance, has a cost-per-life-saved threshold for new road schemes of about 1.5 million GBP per life, or around 30,000 GBP per life year gained. The judgment of our health economists is that somewhere in the region of 20,000-30,000 GBP per quality-adjusted life year is the [threshold...
...Hard to argue with findings like that, but Woloshin and his co-authors offer a thought experiment: Imagine every single person who contracts Disease X dies of it at age 70. If you receive your diagnosis at age 67, you'll be gone well before the 10-year threshold is reached. Now imagine a new technology that spots early signs of the disease at age 57. If everyone gets the test, the 10-year survival rate soars to 100%, but no one in fact lives a single day longer. As with Zocor, early CT scans and early detection...
...Nearly every population group and age is experiencing a severe epidemic," the authors write. Only one of the city's eight wards - an affluent neighborhood in northwest D.C. - has a rate of infection below the 1% epidemic threshold...
...from glaciers around the world, which are pouring water into the oceans and causing them to rise. Up to 600 million people in coastal areas around the world could be at increased risk for flooding. "Unless we take urgent and significant mitigation actions, the climate could cross a threshold during the 21st century committing the world to a sea-level rise of meters," says John Church, an oceanographer at the Centre for Australian Weather and Climate Research and one of the study's co-authors...
