[Q]: 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.

[Q]: The decision by Cleveland County District Judge Thad Balkman in Norman, Oklahoma, came in the first case to go to trial out of 2,700 nationally by states, counties and cities seeking to hold drug companies responsible for the deadly epidemic. Balkman reduced the amount he had awarded in August by $107 million after agreeing with New Brunswick, New Jersey-based J&J that he had made a math error. J&J said it will appeal, and that the award and finding of liability were "neither supported by the facts nor the law." A spokesman for Oklahoma Attorney General Mike Hunter said that office is reviewing the decision and will formally respond within the next few days. Opioids were involved in almost 400,000 overdose deaths from 1999 to 2017, according to the U.S. Centers for Disease Control and Prevention. Following a non-jury trial, Balkman ruled in August that Oklahoma had proven that J&J engaged in misleading marketing about the benefits of painkillers, and that their addictive risks caused a public nuisance in the form of the opioid crisis. Hunter had sought to have J&J pay $17 billion to help fund addiction treatment and other services to repair damage from the opioid epidemic over the next 30 years. Balkman, however, awarded only enough money for one year of programs, saying Oklahoma failed to support its claims regarding the need to abate the epidemic in future years. Following the August ruling, Oklahoma asked Balkman for permission to return to his courtroom annually to prove those costs, but Balkman on Friday maintained his prior ruling. J&J, meanwhile, argued that it deserved a $355 million credit, reflecting pre-trial settlements by the drugmakers Purdue Pharma LP and Teva Pharmaceutical Industries Ltd. Balkman concluded on Friday that state law did not allow such credits. Last month, J&J and four other companies proposed a $48 billion settlement framework to resolve all of the opioid cases they face, with J&J paying $4 billion. Lawyers for the local governments have opposed the proposal. If approved, the settlement would let J&J resolve some of the thousands of product liability lawsuits it faces. The company also faces litigation over whether its baby powder causes cancer, a claim it denies.

[Q]: North Pole, Alaska - the Fairbanks suburb, not the spot at the top of the globe - has posted some of the nation's worst air-quality readings in recent days, thanks to high levels of wood smoke streaming into stagnant cold air. Concentrations of particulates have made North Pole's air "very unhealthy," meaning children, the elderly and other vulnerable people should stay indoors and all residents should refrain from prolonged exercise, according to local government officials. The "very unhealthy" classification was given in the past few days. A search of airnow.gov - the government portal which monitors air quality - did not reveal any other U.S. community currently with such poor quality air. The problem stems from residents' dependence on wood-burning stoves for heat in an extremely cold region prone to pollution-trapping temperature inversions, said officials with the Fairbanks North Star Borough, the regional government. "As long as it's cold and the air is still, we have a particulate problem," said Jim McCormick, a technician with the borough's Air Quality Division. With temperatures in some spots below minus-30 degrees Fahrenheit (-34.4 C) and no relief forecast until next week, the air is expected to stay dirty, McCormick said. As of Friday, particulate pollution in North Pole was worse than in Beijing, which is notorious for chronic air pollution, a Fairbanks newspaper columnist reported, although Reuters was unable to verify the claim independently. Dermot Cole of the Fairbanks News-Miner said his research found only one city in the world, Guangzhou in southern China, with particulate readings that are currently worse than those in North Pole. Alaska's pristine, mountainous landscapes suggest crystal clean air. But the city of Fairbanks also has had recent problems, with air quality classified by the borough on Friday as "unhealthy" - not as dire as in North Pole, but still triggering warnings against outdoor activities. The entire Fairbanks North Star Borough has been plagued for years with wintertime air pollution. It is consistently in violation of federal air-quality standards and is required under federal and state laws to come up with measures to clear the air, although they have proved elusive. A local program that allowed residents to swap out old wood stoves for more efficient models was halted by an anti-regulation initiative that borough voters passed in October. "That stopped it cold," McCormick said.
