question:
Since this story doesn't make claims about efficacy, costs don't seem applicable. We give this story a satisfactory score, but the story could have helped readers understand why measuring surrogate markers such as homocysteine levels can be different than tracking true outcomes such as heart attack or stroke. Here, the surrogate endpoint (homocysteine levels) "improved," but the real endpoint heart attack and stroke did not. There is no discussion of any harms associated with consumption of vitamin B supplements, although such harms would occur from vitamin B intake unlike that studied, so this gets a satisfactory grade. Two of the three studies referred to in the journal article are detailed; a brief reference is given for the third. In addition to the discussion of the studies, a quote was pulled from an editorial in the journal that published the studies. No other treatment options for lowering risk of heart attacks or strokes are mentioned. It's clear from the story that B vitamins have been in use for some time by many people for these purposes. It's clear from the story that B vitamins have been in use for some time by many people for these purposes. We can't be sure if the story relied solely or largely on a news release.
answer:
Study: Heart attacks not cut by B vitamins

question:
The vaccine, developed by U.S. drugmaker Merck & Co, is already being used under emergency guidelines to try to protect people against the spread of a deadly Ebola outbreak in Democratic Republic of Congo. It protects against the Zaire strain of the Ebola virus - the one that most commonly causes outbreaks. The shot is also being reviewed under a fast-track system by regulators in the United States, with a decision expected in the first quarter of next year. "This vaccine has already saved many lives in the current Ebola outbreak, and the decision by European regulators will help it to eventually save many more," the WHO's director-general Tedros Adhanom Ghebreyesus said in a statement. The Congo Ebola outbreak has killed more than 2,100 people since the middle of last year. It is the second-largest Ebola outbreak in history, after a 2013-16 epidemic in West Africa that killed more than 11,300. The Merck vaccine, which the company has now brand-named Ervebo, is likely to get a full marketing license from the European Commission in a few weeks. Roger Perlmutter, president of Merck Research Laboratories, said the company's priority now was to get regulatory approval of its Ervebo manufacturing site in Germany so that licensed supply of the vaccine "can be used to support global public health preparedness". Merck's vaccine is being used in Congo in a so-called "ring vaccination" approach, in which people who may have been in contact with someone newly infected with Ebola are traced and offered the shot to protect them. Charlie Weller, head of vaccines at the Wellcome Trust global heath charity said the Merck shot had already saved "countless lives" in the country. "Having this vaccine available under research conditions has been key in preventing the ongoing outbreak in the DRC spiraling into a repeat of the 2014-16 epidemic, where 11,000 people died," she told Reuters. Health authorities in Kinshasa said last week they planned to introduce an experimental second Ebola vaccine, developed by drugmaker Johnson & Johnson, in the country's eastern provinces in November. The Ebola virus causes hemorrhagic fever and spreads from person to person through direct contact with body fluids. It kills around half of those it infects. There are currently no licensed treatments for the deadly infection, but scientists said in August they were a step closer to being able to cure it after two experimental drugs showed survival rates of as much as 90% in a clinical trial in Congo.

question:
In a study of nearly half-a-million British adults, coffee drinkers had a slightly lower risk of death over 10 years than abstainers. The apparent longevity boost was seen with instant, ground and decaffeinated, results that echo U.S. research. It's the first large study to suggest a benefit even in people with genetic glitches affecting how their bodies use caffeine. Overall, coffee drinkers were about 10 percent to 15 percent less likely to die than abstainers during a decade of follow-up. Differences by amount of coffee consumed and genetic variations were minimal. The results don't prove your coffee pot is a fountain of youth nor are they a reason for abstainers to start drinking coffee, said Alice Lichtenstein, a Tufts University nutrition expert who was not involved in the research. But she said the results reinforce previous research and add additional reassurance for coffee drinkers. "It's hard to believe that something we enjoy so much could be good for us. Or at least not be bad," Lichtenstein said. The study was published Monday in the journal JAMA Internal Medicine. It's not clear exactly how drinking coffee might affect longevity. Lead author Erikka Loftfield, a researcher at the U.S. National Cancer Institute, said coffee contains more than 1,000 chemical compounds including antioxidants, which help protect cells from damage. Other studies have suggested that substances in coffee may reduce inflammation and improve how the body uses insulin, which can reduce chances for developing diabetes. Loftfield said efforts to explain the potential longevity benefit are continuing. Adam Taylor, fetching two iced coffees for friends Monday in downtown Chicago, said the study results make sense. "Coffee makes you happy, it gives you something to look forward to in the morning," said Taylor, a sound engineer from Las Vegas. "I try to have just one cup daily," Taylor said. "Otherwise I get a little hyper." For the study, researchers invited 9 million British adults to take part; 498,134 women and men aged 40 to 69 agreed. The low participation rate means those involved may have been healthier than the general U.K. population, the researchers said. Participants filled out questionnaires about daily coffee consumption, exercise and other habits, and received physical exams including blood tests. Most were coffee drinkers; 154,000 or almost one-third drank two to three cups daily and 10,000 drank at least eight cups daily. During the next decade, 14,225 participants died, mostly of cancer or heart disease. Caffeine can cause short-term increases in blood pressure, and some smaller studies have suggested that it might be linked with high blood pressure, especially in people with a genetic variation that causes them to metabolize caffeine slowly. But coffee drinkers in the U.K. study didn't have higher risks than nondrinkers of dying from heart disease and other blood pressure-related causes. And when all causes of death were combined, even slow caffeine metabolizers had a longevity boost. As in previous studies, coffee drinkers were more likely than abstainers to drink alcohol and smoke, but the researchers took those factors into account, and coffee drinking seemed to cancel them out. The research didn't include whether participants drank coffee black or with cream and sugar. But Lichtenstein said loading coffee with extra fat and calories isn't healthy. ___ Follow AP Medical Writer Lindsey Tanner on Twitter: @LindseyTanner . ____ The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education.
