Input: Consider Input: Paragraph: Repeated attacks on treatment centers by armed militiamen and community members who think Ebola is a conspiracy against them have hampered the response to the second-deadliest outbreak of the hemorrhagic fever in history. In the latest attack, on a hospital in the city of Butembo, a senior World Health Organization (WHO) epidemiologist from Cameroon was killed and two others wounded last Friday. At a protest on Wednesday in Butembo, the biggest city to be affected by the current outbreak, dozens of Congolese doctors and nurses marched behind a banner reading "Ebola exists" and urged authorities to take additional security measures. "If our security is not guaranteed, we will go on strike from the first week of May," Dr. Kalima Nzanzu said, reading from a memo to Butembo's mayor, Sylvain Kanyamanda. Kanyamanda told Reuters that he understood the health workers' frustrations and that the government was determined to respond to their demands. The latest outbreak of Ebola, which was declared last August and is Congo's tenth since the virus was discovered in 1976, is believed to have killed 880 people and infected nearly 500 more in North Kivu and Ituri provinces. The military prosecutor's office in North Kivu said on Wednesday that authorities had captured the suspected ringleader of last week's attack, as well as about a dozen other suspects. Prosecutors believe the assailants belong to an armed group called the Patriotic Union for the Liberation of Congo (UPLC) based on a tract left at the hospital threatening health workers. Dozens of militia are active in eastern Congo's borderlands with Rwanda, Uganda and Burundi, where they run lucrative rackets and fight over land, ethnicity and mineral resources. Claim: Ebola first responders threaten strike if security not improved.

Output: Health workers in one of the epicenters of eastern Democratic Republic of Congo's Ebola outbreak threatened on Wednesday to go on strike as early as next week if authorities don't do more to protect them.

Input: Consider Input: Paragraph: Most people know roughly what a bottle of vitamin D supplements might cost them, so the lack of information on cost is not a significant gap. We appreciate that the story provideddata showing the large and growing amount our society is spending on vitamin Dsupplements ($430 million in 2009), with apparently little health benefit to show for it. The story was mostly concerned with discussing the lack of benefit fromtaking extra vitamin D and calcium. And in this area it excels. While the story does lack precision when itsuggests thatadolescent girls should be getting more calcium (it neverspecifies how much they are getting now, how much more they'd need to meet the recommendations, or what benefits they might expect from this increased intake), it would be difficult for a journalist to come up with any sort of quantifiable benefit or harm estimate from the IOM report. The story captured the overall gist of the problem, which is that the evidence base is complex and still inadequate. The story notes that, contrary to the claims of many advocates for increased supplemental vitamin D, there is evidence thathigh levels of vitamin D mayhave adverseeffects, such as increased risk for fractures and an increasein the overall death rate. The story also explained that too much calcium has been linked to increased risk of kidney stones and, more tentatively, heart disease. The story did a good job of describing how the expert committee conducted its review and what evidence they found. Importantly, it noted that claims of benefit fromextra vitamin D are based onobservational studiesthat most scientists agree "cannot determine cause and effect." We also like that the story solicitedopinions froma variety of expertswith noobvious stake in the controversy. This produced a number of quotes that emphasizedthe need for restraint when interpreting the research on vitamin D. Examples: "I think thisreport will make people more cautious" and "The onus is on thepeople who propose extra calcium and vitamin D to show itis safe before they push it on people." Although we agree with the story's skeptical overall message,we think itmay haveslammed the door just a bit too hard on the possibilityof benefit from supplemental vitamin D. While claims of benefit may not be supported by the currentlyavailable evidence, they have not been conclusively disproved in randomized controlled studies, either. In fact,research isnow underway to determine whether the benefits foundin observational studies of vitamin D can be replicated in more rigorously designed trials. The story probably should have mentioned this research, and left the door to potential benefits open just a crack. No disease-mongering here. The diversity of independent voices included in this story is a real strength. Although it solicits the obligatory comment from a supplement industry spokesman, it didn't go out of its way to find any of the more widely known vitamin D experts,someof whom have been issuing recommendations that are untenable based on current evidence. The enthusiasm of some of these researchersmight beexplained bytheir significant career and financialinterests in promoting vitamin D. Notapplicable for this story. The approaches discussed are not new, and there's notreally any alternative to getting adequate amountsof these essential nutrients. The availability of vitamin D from diet, sunlight and supplements is clear from the story. The novelty of vitamin D and calcium is not really in question, so we'll call this not applicable. This story was not based on a news release. Claim: Report Questions Need for 2 Diet Supplements

Output: In one particularly effective passage, the story quoted a representative of a supplement industry group who disagreed with the report, saying that higherlevels of vitamin D could be beneficial. But it then seguedimmediatelyinto an explanation of why claims from supplementation advocates "are not supported by the available evidence."The key problem, as the story points out, isthat these claimsare based almost exclusively on observationalstudies that can't prove cause and effect and are often skewed by factors the researchers haven't accounted for. Proponents of supplementation also have tended to downplay thepossibility that higher doses of vitamin Dand calcium might cause harma stance which the storynotesmay not be justified. We applaudthis story'seffort toshow readers where the weight of the evidence lies on this issue. Vitamin D isthe latest in a longline of "miracle" nutrients that people have turnedto in the hope of improvingtheir health. As we'velearnedfrom copiousprevious experience, these supplements rarely work as advertised andcan sometimes cause harm at the higher doses people often think will be beneficial for them. More isn't necessarilybetter when it comes to vitamin Dor most other health care interventions for that matter.

Input: Consider Input: Paragraph: "In the Florida governor's race, both Republicans and Democrats have highlighted an issue facing the Sunshine State: a shortage of nurses. For months now, Republican Agriculture Commissioner Adam Putnam has highlighted a surprising factoid about Florida's nursing workforce, often while emphasizing the importance of trade education and career training outside of a four-year bachelor's degree. ""The No. 1 job vacancy in Florida every month for seven years has been nursing,"" Putnam said Oct. 31 during a campaign stop at Whitey's Fish Camp in Fleming Island. Democratic Tallahassee Mayor Andrew Gillum (and Putnam's possible opponent) has also mentioned a nursing shortage in the state, so we wanted to take a look at it. We found that Putnam's claim is backed up by state data, and experts in Florida agreed that the shortage of nurses has been a problem since the 1990s. Data from the Department of Economic Opportunity shows that registered nurses have consistently topped the lists of monthly online job advertisements and annual job openings. Departmentspokeswoman Karen Smith told PolitiFact Florida the top online job advertisement in Florida has been registered nurses every month for the past seven years. We asked for a sample of that data and got a year's worth of monthly reports for Help Wanted OnLine, a tool used by the Department to measure real-time labor demand. These reports are posted on the DEO's site and updated monthly. The most recent month of data (October 2017) shows there were 13,619 online ads placed for registered nurses. The second-most popular ads sought retail salespersons at 7,207 postings, followed by ""first-line supervisors"" for retail sales workers with 6,467 ads. Putnam has also talked about the need for truck drivers, which place fourth for online job ads. In addition, Florida's Statewide Demand Occupations List shows that registered nurses have consistently ranked as the most in-demand occupation since at least 2011. Mary Lou Brunell is the executive director of the Florida Center for Nursing, which was set up in 2001 by the Florida Legislature to address the nursing shortages in the state. In recent years, she said the problem has been exacerbated by a lack of students studying to become nurses, a shortage of faculty teaching future students, and an aging workforce and state population. ""You put all those pieces together, and it's just not getting better,"" said Dianne Morrison-Beedy, the formerdean at the University of South Florida College of Nursing. The nursing workforce is also aging. According to a 2017 report from the Florida Center for Nursing, 44 percent of registered nurses are over the age of 50 and expected to retire in the next 5 to 10 years. The economic turnaround in the late 2000s also decreased the number of nurses in the workforce. When the economy plummeted in 2008, many people trained in nursing but not working returned to their job or delayed retirement. As the economy improved, there were once again more vacancies because those nurses returned home or retired. Brunell also said she's also concerned about the need for licensed practical nurses, which work under the guidance of registered nurses or physicians. She said there's been an increase in home care facilities, which is why she predicts more licensed practical nurses (LPNs)will be needed in the future. Morrison-Beedy said that in order to fix the problem, the focus has to be on the how to develop faculty and support for people who want to become nurses. In Florida, becoming a registered nurse requires either a two-year associate degree or a bachelor's of science degree in nursing. ""We need more students in the baccalaureate program, we need to provide financial support for students to go to school, and in order to do that we have to have enough faculty to teach those students,"" she said. ""We want the best educated and the best kind of nurses because that's where we'll see better outcomes."" Putnam said the No. 1 job vacancy in Florida every month for seven years has been nursing. He's right. The top online job advertisement in Florida has been registered nurses every month for the past seven years. Experts agreed that the shortage has been an issue for awhile in Florida." Claim: The No. 1 job vacancy in Florida every month for seven years has been nursing.
Output: Putnam said the No. 1 job vacancy in Florida every month for seven years has been nursing. He's right. The top online job advertisement in Florida has been registered nurses every month for the past seven years. Experts agreed that the shortage has been an issue for awhile in Florida.
