[EX Q]: Paragraph: The new measures may include screening air travelers for fever when they arrive in the United States from the worst-stricken countries in West Africa, on direct or indirect flights, Schumer said in a statement. He said U.S. Centers for Disease Control and Prevention (CDC) Director Dr. Thomas Frieden told him the agency might adopt some of the recommendations Schumer had made on Ebola screening over the weekend. Those included having the CDC and Customs and Border Protection conduct intense health screening of workers at U.S. ports of entry. The New York Democrat also urged the Department of Homeland Security to create a database of people flying to and from West Africa, which would be shared with hospitals around the country. "The CDC has been doing a very good job thus far in combating the threat, but you can't be too careful when it comes to stopping a deadly epidemic," Schumer said in the statement. The outbreak has killed at least 3,439 people out of 7,492 confirmed, probable and suspected cases since it emerged in Guinea in March, in the worst Ebola epidemic on record. Along with Guinea, the worst-hit countries have been Sierra Leone and Ebola. The disease has also spread to Nigeria and Senegal, but is considered contained there. A man who traveled to Dallas from Liberia last week became the first patient diagnosed with the disease on U.S. soil. In Spain, officials reported on Monday that a nurse had become the first person infected with the hemorrhagic virus in Europe. White House spokesman Josh Earnest said the administration had confidence in the system as it exists but was working on additional safety protocols that would be announced in the coming days. "The president's team is hard at work on developing additional protocols for additional screening measures," Earnest told reporters on Air Force One. Claim: U.S. to require tougher Ebola screening at airports: senator.
[EX A]: U.S. health officials are preparing to require tougher Ebola screening at American airports this week to keep the deadly virus from spreading to this country, Senator Chuck Schumer said on Tuesday.

[EX Q]: Paragraph: Cost is not a component of this story. That is an issue, as the story compares three weight-loss surgical options for morbidly obese individuals, and readers might well be interested in the economics. Also, it would be useful to discuss the costs ofnot having surgery in the matched population. The story does a nice job of making the weight loss comparisonsboth over time for gastric bypass surgery and across surgical optionsclear. The story makes no mention of harms. Bariatric procedures can lead to an array of complications that are worth considering. And on the flip side, it's worth noting that research also hasindicated thatbariatric surgery can both extend quantity and quality of life when compared to not having surgery. Details of the two-part study conducted here are includedand clearly described. And we were also pleased to see several study limitations discussed: "For example, the study included mostly men, so the findings may not apply to women." That said, we do wish more had been said about the study participants, such as averagebody mass index levels before and after the surgeries. Morbid obesity is a major and growing health issue with frustratingly few treatment options. Sources are clearly identified, along with information about their links to the study itself (one scientist was the study's lead researcher, and the other quoted in the story was independent). This is another strong point of the story. The study compared the longer term weight-loss outcomes of the three primary bariatric surgical procedures. The story doesn't make it readily clear how accessible these surgeries are, and who is a good candidate for one. Typically, these procedures are for people over a certain body-mass index, for example. And insurance coverage may or may not pay for it. The story is clear that this study contributes to a growing set of data about long-term weight-loss effects of these surgeries. Duke Medicine issued a newsrelease, and the HealthDay storydoes not rely solely on it. Claim: Weight-Loss Surgery Sheds Pounds Long Term
[EX A]: Bariatric surgeries have been identified as perhaps the most successful means for people who are morbidly obese to lose weight, and use of these procedures is increasing, according to the American Society for Metabolic and Bariatric Surgery. Information about whether the weight-loss results last, and for how long,is a useful addition to the growing medical literature on these surgeries. The study described here by HealthDay speaks directly to the issue in a couple of well-designed analyses, and the story does a good job of explaining both the methods and the results. Missing from an otherwise good narrative is information about the risks of these procedures, as well as their costs and overall availability to the general public. Obesity is a major health issue in the United States, and the use of bariatric surgical procedures is being used increasingly for those who are morbidly obese. Knowing how long people keep the weight offand by how muchis useful for those deciding whether to opt into the procedure. Also of interest is if the health benefits, such as remission of type 2 diabetes, were sustained, though this study didn't appear to investigate that.

[EX Q]: Paragraph: "As the products used in the study are not commercially available, there was no mention of their presumptive costs. (It might have been interesting to explore how fortified margarines compare in cost to those which are not.) The story indicate that there did not appear to be any advantage from the use of the fortified margarines. However the study actually found a suggestion of a statistical benefit in the sub-population of individuals who had had a prior heart attack and who also had diabetes. This is a correction of our originally-posted score on this criterion. The story did, indeed, report that ""there were no harmful side effects."" Adequate description of the study and of its possible limitations. No overt disease mongering. The story included quotes from sources not involved in the study. The story mentioned the increasing number of foods on the shelves that are fortified with omega-3 fatty acids and perhaps the results of this study will make readers question whether such fortification is actually value added. While indicating that the people in the study were receiving optimal medical therapy, the story did not mention other possible means by which individuals who have had a heart attack can lower their chance of having another one. Even one line of such context would have been appreciated and helpful. While indicating that Unilever makes an omega-3 fortified margarine, the story didn't mention that the margarines used in the study were specifically formulated for the study and are not commercially available. However there are commercially available margarines that are fortified with omega-3 fatty acids. Although the story was not clear that the margarines used in the study were prepared exclusively for use in the study, it did indicate that similarly fortified products are commercially available. It's clear that the story did not rely solely or largely on a news release." Claim: Study: More omega-3 fats didn't aid heart patients
[EX A]:
One of 3 stories we reviewed on this study (Reuters and HealthDay were the others), this one did raise some interesting thoughts about why the study failed to show a difference and reported on some of the other types of foods that are now commercially fortified with omega-3 fatty acids. Health claims in food marketing require a great deal of scrutiny. This new data casts some doubt on some past marketing practices. We'll see how and if that changes and if consumer behavior and health care advice changes at all. As a quote in the Reuters story suggests, don't hold your breath waiting for such change.
