Question: Paragraph: Virtually unknown just months ago, New York congressional candidate Alexandria Ocasio-Cortez arrived in Los Angeles as a rising political star, about a month after her improbable upset of 10-term U.S. Rep. Joe Crowley in a New York City Democratic primary. On Thursday, she intentionally avoided politicians and Hollywood celebrities, instead choosing to share the stage at the low-dollar fundraiser with activists pushing for broader rent-control laws in California and a public-backed banking system in the city. In her speech, she warned of a broken economy in which luxury apartments stand vacant while homeless crowd the streets, and talked of a Democratic Party in which the working class and marginalized are ascendant. Bursts of applause followed her calls for universal health care and a cost-free education through college. She swiped repeatedly, if indirectly, at President Donald Trump. "It is not us who are crazy, not with that man in the White House," the former Bernie Sanders organizer said to cheers. Ocasio-Cortez was lauded by those who paid $27, or $10 for students, to see the candidate seen as the new face of the emerging democratic socialist movement. "She really inspires me, because she's so young and she's getting so far," said Melainey Jane Foerster, 16, a high-school student from suburban Santa Clarita. Salesman Jon Pelzer, 65, said he's "impressed by and energized by what she was able to do in New York." "We share all the same values," added Pelzer, a Democrat who ran on a similar platform in California's 30th Congressional District but didn't advance to November. The surprise victory by the political novice in a district that includes parts of the Bronx and Queens came after a low-budget campaign that she built around liberal and social causes, not the traditional Democratic Party machine. Crowley had been expected to win easily. Her platform includes expanding the Medicare program to people of all ages and abolishing Immigrations and Customs Enforcement. Her trip to California comes at a time when state and national Democrats have been contending with friction between their establishment and liberal wings. California Sen. Dianne Feinstein is being challenged in November by a fellow Democrat, state Sen. Kevin de Leon, who has positioned himself as a liberal alternative to the long-serving centrist. She warned of the influence of "coastal elites" in politics, and she recalled that her candidacy was largely dismissed. Ocasio-Cortez said she didn't receive an endorsement from any incumbent "but we won anyway." She urged the crowd to "engage in the fights that you know that are right." Claim: Rising liberal Democrat star on West Coast fundraising swing.

Answer: She visited Los Angeles' notorious Skid Row neighborhood, where the homeless crowd the streets. She met with liberal activists eager to see universal health care and expanded rent-control laws. And she was cheered by hundreds of supporters at a downtown fundraiser, where she warned of those who scheme to turn liberal-minded Americans against each other.

Question: Paragraph: The significant costs of both drugs were mentioned. Nice job. Good job describing the benefits reported in the two drug studies. The two papers present a bewildering array of statistics. This story did a nice job distilling the information into a couple of very understandable sentences. Good job explaining signifcant potential harms of both drugs something competitors didn't do at all. Nice job, including linking (in the online version) to the papers in the New England Journal of Medicine. No disease-mongering of melanoma. Several independent sources cited. The story adequately explained the comparisons between both new drugs and the older dacarbazine chemo drug. Vemurafenib was described as experimental and as "expected to be approved by the FDA within a few months." Ipilimumab was explained to be approved in March and already on the market. The relative novelty of both drugs was well explained. It's clear that the story did not rely on a news release. Claim: Drugs Show Promise Slowing Advanced Melanoma

Answer: The story made strong, clear attempts to report in a restrained manner, using terms/phrases such as: "notable progress" "do not cure" "might add two to several moths to expected lifespans" "To be sure, more than half of patients with metastatic melanoma would not be helped all that much by either drug." Stories about cancer perhaps especially melanoma because of its treatment challenges should balance promise with realistic context. This story did a better job of that than the competitors' efforts we reviewed.

Question: Paragraph: The story doesn't address costs for any of the treatment options discussed. Is MBSR comparable to CBT? Does insurance cover either treatment option? The story tells readers what percentage of study participants who got MBSR treatment reported improvement in pain, as well as what percentage of MBSR participants "reported improvement in the activities they could do." It also offered the same numbers for participants who received CBT and for the control group, which received typical medical care for this condition. These detailsdeservea Satisfactory rating. But: The story notes: "The study did caution that 30 of the 103, or about one-third, of the participants in the meditation group reported an 'adverse event,' most often an increase in pain due to yoga." It's good to see that included. Since the story is effectively comparing MBSR to CBT and conventional treatment, it would also have been worth noting "adverse events" for those groups in the study. According to the study, 10 percent of the CBT group also experienced "adverse events," and no adverse events were mentioned for the control group. Defining "adverse events" would also have been good, since it's not clear whether they mean momentary pain or a debilitating flare-up of long-term pain. According to the study, the painfor both MBSR and CBT groupswas "mostly temporary" and no "serious" adverse events were reported. Those things are worth mentioning. (It's also worth finding out what "mostly" and "serious" mean.) The story describes the study in detail, explicitly stating the study size and the absolute percentages in each arm that had benefit. It also acknowledged the study was randomized. We'll count this as sufficient for Satisfactory, keeping in mind the following: As explained in the summary above, the story doesn't make clear MBSR and CBT were used in addition to conventional medical treatment, rather than instead of medical treatment. The story didn't mention that the study excluded participants with what the study authors term "a specific diagnosis (eg, spinal stenosis)." In other words, the study did not address treatments for back pain caused by issues like a herniated disc or rheumatoid arthritis. Many readers have these conditions, and should be informed thatthese study results may not be applicable to their situation. Lastly, we would have welcomed a discussion of the high rates of success within thecontrol group. Forty-four percent in that group experienced a gain in functionality, for example. That seems pretty good! What do the researchers have to say about that? No disease mongering here. However, we did want to point out that the story "fear mongers" in a sense, by stating back pain is "one reason why more and more people are addicted to painkillers." The story insinuates that these other treatment methodsespecially meditationcould help with that. And maybe they could. But the study itself says "No overall differences in treatment effects were observed forself-reported use of medications for back pain." So why the mentionof painkiller addiction? Conflicts of interest don't appear to be an issue here, and the story includesstatements froman accompanying editorial in JAMA, which was written by experts unaffiliated with the research. This squeaks by as Satisfactory, though it should be noted that most of this material was available via news releases (see below). The story is effectively all about comparing alternatives, thoughagainit should have made clear that MBSR and CBT were used in conjunction with conventional medical treatment, and it left out discussion of other well-known non-medication treatment methods, such as exercise. It's not clear from the story whether MBSR is widely available, is available in mainly metropolitan areas, or is a relatively new field that is still uncommon. The story does quote from a separate editorial in JAMA that says health care systems "should provide access to affordable mind-body therapies,"implying that it's not widely available. Is this the case, or can it be easily accessed? Given the constraints of a brief news story, the piece does a nice job of articulating the differences between MBSR and CBT. It wouldhave been even more helpful for the story to mention previous studies on the impact of MBSR and CBT on low back pain, to help us understand how novel this new study is. There is little in the story that is not found in the two news releases issued on this study. (Those releases can be found here and here.) Claim: Mindful meditation may be the answer to relieving chronic back pain, study suggests

Answer:
This story focuses on a JAMA studyinvestigating whethermindfulness-based stress reduction (MBSR) is as effective as cognitive behavior therapy (CBT) and standard treatment at helping patients reduce lower back pain. The story does a good job of quantifyingthe benefits and risks seen in the study. However, there were three things we wanted to call special attention to: Lower back pain is an extremely common problem around the world. For example, a 2012 paper reported that lower back pain was responsible for more than three percent of all emergency room visits in the United States. An earlier paper found that health care expenditures in the U.S. directly attributable to back pain came to around $26 billion. When we consider the number of people affected by back pain, and the related economic impact, it's clear that any research that offers insight into how to effectively treat lower back pain is worth covering.
