Question: Paragraph: "The cost of the drug wasn't mentioned a big oversight. Other news stories pegged it at about $35,000 a year. Adequate job. The story explained: ""But experts stress that Benlysta is not a miracle drug: It only worked in 35 percent of North American patients tested and was not effective for patients with the deadliest form of the disease. Additionally, it did not show positive results in African Americans, who are disproportionately affected by lupus."" There was no discussion of harms. An NPR story, by comparison, pointed out that ""There are side effects, of course, and some of them are pretty serious. In clinical tests involving about 2,100 people, 11 taking Benlysta died compared with 4 getting placebo. About 6 percent of people taking Benlysta got serious infections compared with 5.2 percent on placebo."" The story offered an interesting historical perspective on the evidence: ""The company originally tested Benlysta, known generically as belimumab, as a treatment for rheumatoid arthritis. When a mid-stage trial in lupus patients failed to meet researchers' goals in 2006, many analysts wrote the drug off and downgraded the company's stock. But when scientists reanalyzed the data they found that the drug helped block the antibodies that cause lupus symptoms in a subset of patients."" No disease mongering of lupus. Two independent sources were quoted. Not applicable. With no other new drug approved for lupus in 56 years, there's not been much to compare it with. The story did state that some experts thought this ""could prompt development of other drugs that are even more effective in treating the debilitating immune system disorder."" The focus of the story is FDA approval of the new drug. The headline explains that the FDA approved the first new drug for lupus in 56 years. It's clear the story did not rely solely on a news release." Claim: FDA approves first new drug for lupus in 56 years

Answer: "Good caveats, including in the patient profiled, who said, ""It's a bittersweet thing for me because I have friends with lupus for whom this drug won't work. There's no one-size-fits-all for lupus and I'm just extremely fortunate that my lupus is mild and is helped by Benlysta."" The story should have discussed potential harms and costs. As the story explained, this was not only the first new lupus drug approved in 56 years, but it could be ""a milestone that medical experts say could prompt development of other drugs that are even more effective in treating the debilitating immune system disorder."""

Question: Paragraph: Homebred beef cattle are seen at a local cattle market in Hongseong, about 170 km (106 miles) south of Seoul July 29, 2008. A rare genetic mutation may underlie some cases of mad cow disease in cattle and its discovery may help shed light on where the epidemic started, U.S. researchers reported on Friday. REUTERS/Lee Jae-Won The mutation, in an Alabama cow that tested positive in 2006 for bovine spongiform encephalopathy, or BSE, is identical to one that causes a related brain-wasting disease in humans. This suggests BSE may sometimes arise spontaneously in cattle. Jurgen Richt of Kansas State University said cattle producers must never let down their guard against BSE because cattle anywhere, at any time, can develop the disease. The finding may support a 2005 theory that the BSE epidemic in cattle could be traced to feed contaminated with cattle remains from India, the researchers report in the Public Library of Science journal PLoS Pathogens. BSE or mad cow disease swept through British dairy herds in the 1980s, forcing the destruction of millions of animals. No one ever found where it came from but most experts thought at the time it came from cattle feed that contained the remains of sheep infected with a similar disease called scrapie. Cattle were never known to develop BSE before the epidemic, but some experts have argued they may have. This report lends credence to that idea. BSE, scrapie and a human version called Creutzfeldt-Jakob disease, or CJD, are brain-destroying illnesses called transmissible spongiform encephalopathies. In some cases, animals or people that eat brain and nervous system material from victims of these diseases can develop them, too. They are passed along by misfolded infectious protein fragments called prions. A very rare disease called variant CJD has been found in people who ate infected beef products. Fatal and incurable, it has affected just 167 people so far. Most countries now ban the use of meat and other parts from mammals in food for cattle. They also ban the use of potentially infectious tissues such as brain and spinal cord in human food. "There are tendencies around the world, now that the feed-borne epidemic has gone down, to relax these rules and regulations," Richt said in a telephone interview. "So if we have these genetic cases popping up here and there and we don't have our mitigations in place, we will have another epidemic somewhere." He suggested breeding the gene out of cattle. "We can clean the world cattle herd of that mutation," Richt said. CJD is also known to pop up spontaneously in the human population. A genetic mutation causes the disease in one in a million people globally. Richt and colleagues tested the brain of the Alabama cow and found a mutation identical to the prion gene mutation that causes some cases of CJD. It is probably rare in cattle, found in fewer than one in 2,000, they said in the report, published here But the animal passed along its mutation to its heifer, which suggests it is inherited. Claim: Gene mutation underlies some mad cow disease: study.

Answer: A rare genetic mutation may underlie some cases of mad cow disease in cattle and its discovery may help shed light on where the epidemic started, U.S. researchers reported on Friday.

Question: Paragraph: The measure would give state public health officials instead of local doctors the authority to decide which children can skip their shots before attending school. It's being considered by the state Assembly amid growing cases of measles. Newsom told reporters at the California Democratic Party Convention Saturday that although he supports immunization, he has concerns about having government officials sign off on vaccine exemptions. He said as a parent, he wouldn't want a bureaucrat to make a personal decision for his family. The Sacramento Bee reports Newsom didn't mention the bill explicitly. Opponents say the doctor-patient relationship will be compromised if it becomes law. California does not allow exemptions based on personal beliefs, but still allows exemptions for children who must avoid vaccinations for medical reasons. Claim: California governor has doubts about tougher vaccine rules.

Answer:
Gov. Gavin Newsom says he has concerns about enacting tougher rules that limit doctors from granting medical exemptions for children's vaccinations.
