[EX Q]: 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 provided data showing the large and growing amount our society is spending on vitamin D supplements ($430 million in 2009), with apparently little health benefit to show for it. The story was mostly concerned with discussing the lack of benefit from taking extra vitamin D and calcium. And in this area it excels. While the story does lack precision when it suggests that adolescent girls should be getting more calcium (it never specifies 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 that high levels of vitamin D may have adverse effects, such as increased risk for fractures and an increase in 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 from extra vitamin D are based on observational studies that most scientists agree “cannot determine cause and effect.” We also like that the story solicited opinions from a variety of experts with no obvious stake in the controversy. This produced a number of quotes that emphasized the need for restraint when interpreting the research on vitamin D. Examples: “I think this report will make people more cautious” and “The onus is on the people who propose extra calcium and vitamin D to show it is safe before they push it on people.” Although we agree with the story’s skeptical overall message, we think it may have slammed the door just a bit too hard on the possibility of benefit from supplemental vitamin D. While claims of benefit may not be supported by the currently available evidence, they have not been conclusively disproved in randomized controlled studies, either. In fact, research is now underway to determine whether the benefits found in 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, some of whom have been issuing recommendations that are untenable based on current evidence. The enthusiasm of some of these researchers might be explained by their significant career and financial interests in promoting vitamin D. Not applicable for this story. The approaches discussed are not new, and there’s not really any alternative to getting adequate amounts of 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
[EX A]: In one particularly effective passage, the story quoted a representative of a supplement industry group who disagreed with the report, saying that higher levels of vitamin D could be beneficial. But it then segued immediately into an explanation of why claims from supplementation advocates “are not supported by the available evidence.” The key problem, as the story points out, is that these claims are based almost exclusively on observational studies 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 the possibility that higher doses of vitamin D and calcium might cause harm–a stance which the story notes may not be justified. We applaud this story’s effort to show readers where the weight of the evidence lies on this issue. Vitamin D is the latest in a long line of “miracle” nutrients that people have turned to in the hope of improving their health. As we’ve learned from copious previous experience, these supplements rarely work as advertised and can sometimes cause harm at the higher doses people often think will be beneficial for them. More isn’t necessarily better when it comes to vitamin D–or most other health care interventions for that matter.

[EX Q]: Paragraph: The city said in a release that it will spend $9.4 million to boost its mobile mental health treatment teams, which were launched in 2016. The city said the new money will be part of a $21 million investment that will lead to the hiring of more social workers, housing specialists and legal assistance employees. The additional workers will be needed to process the 20% increase in mental health referrals the effort is expected to generate, the city said, adding that it will likely reach 900 more people annually. In addition, the city said it plans to spend $11 million to create hospital-based outreach teams to coordinate care for people who frequent emergency rooms and acute care facilities. Mayor Bill de Blasio said the initiative will keep neighborhoods safer. “We have an obligation to address our broken mental health system and do all we can to connect people who are struggling to treatment,” de Blasio said. “That includes the small percentage of those with mental illness that, left untreated, are at risk of committing violence against themselves or others.” The city said its mobile units are in addition to a program that teams up mental health professionals with police officers who engage clients with serious mental health needs and a history of violence. The goal, it said, is to connect those individuals to professional treatment and support systems such as housing or family. Claim: New York City expands mobile program to reach mentally ill.
[EX A]: New York City is expanding a program to use mobile units to reach hundreds of people who are mentally ill, the city announced Monday.

[EX Q]: Paragraph: The outbreak, the country’s worst, has killed 439 of the 713 people believed to have caught the disease. The fight against Ebola depends on tracing people who may have had contact with the disease and could fall ill and spread it further. But the outbreak in a region of Congo with frequent fighting makes it hard for health workers to move around and monitor potential sufferers and to spread messages about how to avoid becoming sick. Most of the cases since the start of the year have been in Katwa health zone, where the WHO said Ebola workers had faced “pockets of community mistrust” and most people falling ill were not on lists of people suspected of coming into contact with Ebola. “The outbreak has also extended southwards to Kayina health zone, a high security risk area,” the WHO said in its statement late on Thursday. There have been five cases in Kayina, which lies between the main outbreak zone and the major city of Goma, which is close to the Rwandan border. The WHO said that after running an Ebola simulation exercise in Rwanda, it was sending a team to beef up the country’s preparedness and to vaccinate health workers who would be first to come into contact with Ebola if it spread across the border. However, WHO spokeswoman Fadela Chaib said there had also been a decline in cases around the previous hotspot Beni. “It is very premature to shout victory, it’s true we had some success in Beni because all the steps we’ve taken have had an impact, but unfortunately we see cases turning up in other areas,” she said. “The country is not only facing Ebola but other health threats, just to name malaria, cholera, vaccine-derived polio, and also a very long humanitarian crisis and a lot of violence in several regions.”  More than 60,000 people have been vaccinated in Congo, as well as 2,500 in Uganda, one of the countries at “very high” risk from the disease. Chaib said there were 4,000 people with potential Ebola contact under surveillance and 156 patients in hospital. Claim: Ebola spreads to high-risk area of Congo: WHO.

Democratic Republic of Congo’s Ebola outbreak has spread southwards into an area with high security risks, the World Health Organization said.
