Paragraph: The article states that acupuncture costs $45 to $100 per session. It does not say how this compares to other treatments and whether the cost of care is the same, more or less than alternatives. The story states the proportion of patients who successfully responded to each therapy, and clearly explains that "real" acupuncture was no better than sham needling. But it does not define success or otherwise quantify how much people improved clinically in either relative or absolute terms. For a treatment to be considered successful, a patient must have reported either a 33% improvement in pain or as little as a 12% improvement in function during an interview conducted over the telephone 6 months after enrollment. Nonethless we'll grade this criterion as satisfactory. The story did not mention harms from any of the treatments patients received. Previous research suggests that acupuncture poses few risks when performed with sterile, disposable needles. The article describes the largest randomized controlled trial to date investigating the effectiveness of acupuncture for treating chronic low back pain, and reports its published results. It discusses the three treatment groups studied and potential reasons for the outcomes observed. There are no obvious elements of disease mongering. The story explains that the study participants were people with chronic low back pain. These results wouldn't apply to other back pain conditions. The article cites one of the study's coauthors and two physicians who appear to be users and/or proponents of complementary therapies. It would have been interesting to hear from a skeptical observer. The story lists the therapies received by patients assigned to the conventional medicine group. The literature suggests that these treatments generally provide very modest benefits. The article does not mention other therapies that may be effective for managing chronic pain and improving flexibility and strength. These include cognitive therapy alone or in combination with intensive exercise and strengthening. Acupuncture is estimated to be the third most popular complementary therapy for chronic low back pain. Though the article does not say much about its availability, readers are likely to be familiar with it. The story notes that this is the largest study yet of acupuncture for chronic back pain, suggesting that the treatment is not new. There is no obvious use of text from a press release. Claim: Acupuncture, real or fake, called best for lower back pain
This article reports on the largest randomized controlled trial to date investigating the effectiveness of acupuncture for treating chronic low back pain. It explains that both acupuncture and sham needling are more effective than conventional medical therapies, but that "fake acupuncture works nearly as well as the real thing." In addition to describing the quality of the evidence, the story mentions several other treatment options, tells the reader the cost of acupuncture, and hints at its novelty. The story neglects to mention harms. (A recent systematic review reinforces the study's finding that acupuncture poses few risks; see Spine 2005;30:944-63). And it also provides an incomplete picture of the treatment's apparent benefits. Although it notes the proportion of patients who improved with each therapy, it does not define success or otherwise quantify how much people improved clinicallyin either relative or absolute terms. For a treatment to be considered successful, for example, a patient could have reported as little as a 12% improvement in function during an interview conducted over the telephone 6 months after enrollment. This is important information if people are to weigh the apparent benefit of a therapy against its cost. The article cites one of the study's coauthors and two physicians who appear to be users and/or proponents of complementary therapies. They attempt to explain why needling seems to work. To provide some balance, the study's coauthor suggests that the apparent benefit could merely be the result of patients' expectations of improvement from acupuncture, on the one hand, and of poor results from conventional medicine on the other. (Unfortunately, the researchers did not measure patients' expectations.) It would have been interesting to hear from others. Some might point out that the new study shows that acupuncture and sham needling are only more effective than treatments that are not themselves very effective. Others might make the case that acupuncture provides no specific treatment effect and is unethical to usebecause it could be construed as prescribing a placebo. People with chronic low back pain are desperate for anything that will help. When a large new study provides apparently strong evidence to buttress a therapy that previously had little high-quality evidence to support it, readers might also benefit from more context. A major systematic review that analyzed 35 randomized trials involving 2861 patients recently concluded that acupuncture appears to confer modest, short-term pain relief, but that the quality of the studies was not very good. The reviewers were careful not to overstate the benefits of acupuncture (Spine 2005;30:944-63). Overall, this was a good article that would have been helped by some more context.

Paragraph: The Paris regional administration suspended the job of removing hazardous substances from the fire-ravaged Paris cathedral last month under pressure from labor inspectors concerned about health risks for workers. The administration had said that when the lead-removal work resumed, stricter safety procedures, new equipment and allowing much fewer workers inside at a time would "prevent any release of polluting elements to the outside." But representatives from environmental groups and the CGT union said at a news conference Monday they don't think the government safeguards go far enough. They asked for a regularly updated chart showing the level of lead in the air. Labor and environmental groups are also pushing for the creation of a medical center to monitor of firefighters, workers and residents. Paris Deputy Mayor Anne Souyris said updated measurements of lead levels are set for release on Tuesday. The decontamination work is scheduled to resume Wednesday, starting with the square in front of Notre Dame and adjacent streets, Souyris said. Hundreds of tons of lead that was in Notre Dame's spire and roof melted during the April 15 fire, which came close to destroying the cathedral. Lead levels remain elevated at some spots inside and in the soil of the adjacent park and forecourt, according to the Paris regional health agency. Those areas have been closed to the public since the fire. The environmental activists and union officials said they want a containment shield built over Notre Dame to keep more lead from being released into the atmosphere. "For the efficiency of the decontamination measures within the area, it is absolutely necessary that the site is confined", Annie Thebaud-Mony, co-founder of health and environment group Henri Pezerat, said. Notre Dame rector Patrick Chauvet acknowledged that lead can escape into the environment from a big hole in the cathedral's roof but ruled out building a containment shield before the decontamination work resumes. Paris authorities ordered new checks of schools and day care centers in the Notre Dame neighborhood and recommended blood tests for children under age 7 and pregnant women who live nearby. Children are especially vulnerable to health problems from lead poisoning and exposure. Claim: France: Groups want Notre Dame enclosed during lead cleanup.
Environmental groups and one of France's largest labor unions called Monday for a containment shield and other safety measures to ensure decontamination work at Notre Dame Cathedral does not expose workers and residents to unsafe levels of lead.

Paragraph: The Trump administration has called for 30 days of measures, including staying at least six feet away from other people, that have upended American life as most people stay isolated at home, shuttering schools and closing businesses through at least the end of April, with some states continuing certain closures through May and June. Dr. Anthony Fauci, the head of the National Institute of Allergy and Infectious Diseases, said such steps must continue but that there are hopeful signs they are working. "If in fact we are successful, it makes sense to at least plan what a re-entry into normality would look like. That doesn't mean we're going to do it right now, but it means we need to be prepared to ease into that," Fauci, a member of the White House coronavirus task force, told Fox News in an interview. Fauci and other public health experts have said the strict measures are needed to control the fast-spreading and potentially fatal disease that has already led to about 400,000 confirmed COVID-19 U.S. cases and nearly 13,000 deaths, even as the shutdowns have roiled the U.S. economy. Dr. Deborah Birx, another task force member, said isolation measures must continue for now or else the country could risk a repeated spike despite the allure of warmer spring weather. "What's really important is that people don't turn these early signs of hope into releasing from the 30 days to stop the spread. It's really critical," she told NBC News' "Today" program. "If people start going out again and socially interacting, we could see a really acute second wave." Asked if 30-day distancing practices would be enough or that steps might have to continue longer, she said officials were looking at each area of the country differently as they weigh the data. "Clearly, there are metro areas that are struggling," Birx said. Claim: U.S. planning ways to 'ease' back to normal if virus efforts work: Fauci.
U.S. health officials are planning ways for the country to return to normal activities if distancing and other steps to mitigate COVID-19 this month prove successful in curbing the outbreak, the top U.S. infectious disease official said on Wednesday.
