[Q]: Paragraph: The Food and Drug Administration approved Medtronic's CoreValve system based on U.S. clinical trials in which it was shown to be safe and effective while demonstrating low rates of stroke and valve leakage, the company said. CoreValve, in which the replacement valve is threaded into place through an artery using a catheter, spares patients chest-cracking surgery. The system has been available since 2007 in Europe, where it is not uncommon for medical devices to win approval several years ahead of the United States. Claim: U.S. FDA approves Medtronic heart valve replacement system.
[A]: Medtronic Inc's non-invasive systems for replacing diseased heart valves won U.S. approval for use in patients deemed too frail to endure traditional open heart surgery, the U.S. medical device maker said on Friday.

[Q]: 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
[A]: 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.

[Q]: Paragraph: "One of the questions about the state budget proposal that Gov. John Kasich is expected to announce in February is whether the state will follow through with the Affordable Care Act's expansion of Medicaid coverage. The federal health care law would expand coverage to people with incomes up to 138 percent of the poverty level -- a provision which was made optional under the U.S. Supreme Court ruling that otherwise upheld the law. A bipartisan group of 85 health coverage organizations has written to the governor saying anything less than the full 138 percent would cause people to drop or skip coverage, endangering their health. Terry Russell, executive director of the National Alliance on Mental Illness of Ohio, told Gongwer News Service that mentally ill Ohioans struggle to stay employed, and that local mental health agencies have marginal resources to help. ""The sad statistic that haunts us every day is that individuals with mental illnesses die an average of 25 years earlier than those without a mental illness,"" he said. ""Sixty percent of these premature deaths are the result of preventable and treatable diseases, such as heart disease, diabetes, cancer and infections."" PolitiFact Ohio checked into his claim about 25 years, and quickly found his statement was right on the money. A study published in 2006 by the National Association of State Mental Health Program Directors that was the focus of wide attention and concern in the mental health community looked at data from 16 states, including Ohio. It found that, on average, people with severe mental illness die 25 years earlier than the general population. The figure for Ohio was actually worse. People with severe mental illness die 32 years earlier. Calling it ""a serious public health problem for the people served by our state mental health systems,"" the study said about 60 percent of premature deaths are due to conditions such as cardiovascular, pulmonary and infectious diseases. A number of factors contribute to risk, the study said, including modifiable factors like obesity, poor nutrition and alcohol and tobacco use. People with severe mental illness have poorer access to appropriate health care, and may be additionally vulnerable because of higher rates of homelessness, victimization, unemployment and poverty. Among its recommendations, the report called for better access to physical health care for people with serious mental illnesses to fight what it called an ""epidemic of premature death and its contributing causes."" Russell said that people with mental illnesses, on average, die 25 years earlier than those without a mental illness. He accurately cited findings of a major study on the issue. And in Ohio, the average is actually greater than 25 years. On the Truth-O-Meter, his claim rates ." Claim: Individuals with mental illnesses die an average of 25 years earlier than those without a mental illness.
