AMA Calls For Ban On Direct-To-Consumer Advertising of Prescription Drugs (ap.org)
HughPickens.com writes: The Associated Press reports that the American Medical Association has called for a ban on direct-to-consumer ads for prescription drugs and implantable medical devices, saying they contribute to rising costs and patients' demands for inappropriate treatment. According to data cited in an AMA news release, ad dollars spent by drugmakers have risen to $4.5 billion in the last two years, a 30 percent increase. Physicians cited concerns that a growing proliferation of ads is driving demand for expensive treatments despite the clinical effectiveness of less costly alternatives. "Today's vote in support of an advertising ban reflects concerns among physicians about the negative impact of commercially-driven promotions, and the role that marketing costs play in fueling escalating drug prices," said the AMA's Patrice A. Harris. "Direct-to-consumer advertising also inflates demand for new and more expensive drugs, even when these drugs may not be appropriate."
The AMA also calls for convening a physician task force and launching an advocacy campaign to promote prescription drug affordability by demanding choice and competition in the pharmaceutical industry, and greater transparency in prescription drug prices and costs. Last month, the Kaiser Family Foundation released a report saying that a high cost of prescription drugs remains the public's top health care priority. In the past few years, prices on generic and brand-name prescription drugs have steadily risen and experienced a 4.7 percent spike in 2015, according to the Altarum Institute Center for Sustainable Health Spending. -
Does Higher Health Care Spending Lead To Better Patient Outcomes?
First time accepted submitter ericjones12398 writes "If you haven't seen the words 'health care' in news headlines lately, you must be living under a rock. What seems most controversial among the latest research and news is a flawed payment scale that undervalues primary care and overvalues specialty care. There is evidence suggesting that publicly funded health care spending (i.e., Medicare) has not been based on primary health care needs. Rather, In the U.S. Medicare spending relies on a resource-based relative value scale (RBRVS) which seems to promote higher spending without evidence of better patient outcomes. A study comparing spending and mortality rates in Ontario had the opposite findings however, supporting a link between higher spending and better outcomes for patients. What are we doing different in the U.S.? " -
Bionic Leg Undergoing Clinical Trials
fangmcgee writes "A 'bionic' leg designed for people who have lost a lower leg is undergoing clinical trials sponsored by the US Army. The researchers hope the leg will be able to learn the patient's nerve signal patterns and be able to move in response to the patient's own muscles and nerves (abstract). Electrodes are attached to nine muscles in the thigh to detect the patterns in which the nerve signals are fired. Different patterns correspond to different intended movements. In the current stages of training, the volunteers are wired up to the electrodes and learn how to use the muscles to make a computer avatar move on screen. Results showed that all the volunteers could control the avatar’s knee and ankle movements from neural information from the thigh, with amputees achieving 91 percent accuracy of movement and the non-amputees achieving 89 percent." -
Cell Phone Use Tied To Changes In Brain Activity
Takichi writes "The New York Times is reporting on research linking cell phone use and increased metabolism, with high statistical significance, in the areas of the brain close to the antenna. The study was led by Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, and is published (abstract) in the Journal of the American Medical Association. The impact, good or bad, of the increased stimulation is speculative, but this research shows there is a direct relationship between cell phone signals and the brain that warrants further study." -
Acupuncture May Trigger a Natural Painkiller
Pickens writes "USNWR is reporting that the needle pricks involved in acupuncture may help relieve pain by triggering the natural painkilling chemical adenosine. There are also indications that acupuncture's effectiveness can be enhanced by coupling the process with a well-known cancer drug — deoxycoformycin — that maintains adenosine levels longer than usual. Dr. Maiken Nedergaard of the University of Rochester Medical Center and her colleagues administered half-hour acupuncture treatments to a group of mice with paw discomfort. The investigators found adenosine levels in tissue near the needle insertion points was 24 times greater after treatment, and those mice with normal adenosine function experienced a two-thirds drop in paw pain. By contrast, mice that were genetically engineered to have no adenosine function gained no benefit from the treatment." Read below for some acupuncture skepticism engendered by other recent studies.
However, many remain skeptical of acupuncture claims. Ed Tong writes in Discover Magazine that previous clinical trials have used sophisticated methods to measure the benefits of acupuncture, including 'sham needles' (where the needle's point retracts back into the shaft like the blade of a movie knife) to determine if the benefits of acupuncture are really only due to the placebo effect. 'Last year, one such trial (which was widely misreported) found that acupuncture does help to relieve chronic back pain and outperformed "usual care". However, it didn't matter whether the needles actually pierce the skin [paper here with annoying interstitial], because sham needles were just as effective,' writes Tong. 'Nor did it matter where the needles were placed, contrary to what acupuncturists would have us believe.'" -
Ginkgo Doesn't Improve Memory Or Cognitive Skills
JumperCable writes "Ginkgo biloba has failed — again — to live up to its reputation for boosting memory and brain function. Just over a year after a study showed that the herb doesn't prevent dementia and Alzheimer's disease, a new study from the same team of researchers has found no evidence that ginkgo reduces the normal cognitive decline that comes with aging. In the new study, the largest of its kind to date, DeKosky and his colleagues followed more than 3,000 people between the ages of 72 and 96 for an average of six years. Half of the participants took two 120-milligram capsules of ginkgo a day during the study period, and the other half took a placebo. The people who took ginkgo showed no differences in attention, memory, and other cognitive measures compared to those who took the placebo, according to the study, which was published in this week's Journal of the American Medical Association." -
New Success For Brain-Controlled Prosthetic Arm
An anonymous reader writes "A number of amputees are now using a prosthetic arm that moves intuitively, when they think about moving their missing limb. Todd Kuiken and colleagues at the Rehabilitation Institute of Chicago surgically rearrange the nerves that normally connect to the lost limb and embed them in muscles in the chest. The muscles are then connected to sensors that translate muscle movements into movement in a robotic arm. The researchers first reported the technique in a single patient in 2007, and have now tested it in several more. The patients could all successfully move the arm in space, mimic hand motions, and pick up a variety of objects, including a water glass, a delicate cracker, and a checker rolling across a table. (Three patients are shown using the arm in the related video.) The findings are reported today in Journal of the American Medical Association." -
RFID Tags Can Interfere With Medical Devices
An anonymous reader writes "A new study suggests RFID systems can cause 'potentially hazardous incidents in medical devices.' (Here is the JAMA study's abstract.) Among other things, electrical interference changed breathing machines' ventilation rates and caused syringe pumps to stop. Some hospitals have already begun using RFID tags to track a wide variety of medical devices, but the new finding suggests the systems may have unintended consequences." -
YouTube Breeding Harmful Scientific Misinformation
Invisible Pink Unicorn writes "University of Toronto researchers have uncovered widespread misinformation in videos on YouTube related to vaccination and immunization. In the first-ever study of its kind, they found that over half of the 153 videos analyzed portrayed childhood, HPV, flu and other vaccinations negatively or ambiguously. They also found that videos highly skeptical of vaccinations received more views and better ratings by users than those videos that portray immunizations in a positive light. According to the lead researcher, 'YouTube is increasingly a resource people consult for health information, including vaccination. Our study shows that a significant amount of immunization content on YouTube contradicts the best scientific evidence at large. From a public health perspective, this is very concerning.' An extract from the Journal of the American Medical Association is available online." -
Does Computer Use Actually Cause Carpal Tunnel?
BoldAC writes "A geek physician has reviewed the medical literature that explores if a relationship exists between computer use and carpal tunnel syndrome. 'Typing at the keyboard or using the mouse for hours and hours upon end just seems like it has to be horrible for your joints, right?' His conclusions certainly seem to contradict the thinking of many: 'The current research shows that computer use has very little role in causing carpal tunnel syndrome.' It even seems that both Harvard and the Journal of the American Medical Association agree with his conclusions." -
Doctor Urges AMA To Classify Gaming Addiction
Doctor Mario writes "The AMA has issued a set of findings and recommendations (Word document) which follow a lengthy look at possible connections between gaming and violence, as well as gaming addiction. Ars Technica has a very good summary of the report, which suggests that gaming addiction is likely to be a subset of Internet addiction 'as it most frequently occurs in players of MMORPGs. In both of these addictions, the current definition is currently informal — the described symptoms actually most closely resemble pathological gambling, rather than an addiction. In either case, the report notes, "there is currently insufficient research to definitively conclude that video game overuse is an addiction."' The report also recommends that Internet and videogame addiction be included in a revision to the Diagnostic and Statistical Manual of Mental Disorders." -
Study Shows One Third of All Studies Are Nonsense
SydShamino writes "CNN has a report on new research to confirm claims made in initial, well-publicized studies. According to the new study, about a third of all major studies from the last 15 years were subsequently shown to be inaccurate or overblown. The study abstract is available." -
Killer Ozone?
Tufriast writes "This will make you think twice about an H2... The BBC News has reported that the death toll in U.S. cities might have a correlation to the ozone levels in them. The article mentions several major U.S. cities, and notices the upward trend in premature deaths as pollution levels rise. The results can also be found in the Journal of the American Medical Association." -
Game Content Ratings Not Always To Be Trusted?
Thanks to Reuters for its article discussing video games rated 'T' for teens containing 'explicit' content that's not noted on the game box. According to Harvard-based researchers checking on the voluntary ESRB ratings for videogames: "Although most of the games' content matched their ratings, [the survey] found that 48 percent of games contained some content that was not noted on the game box." The piece goes on to note specific examples: "For instance, 12 of the 81 games showed the use of substances such as tobacco and alcohol, while only 1 game had received that type of content descriptor from the ESRB. And while the researchers reported sexual content in 22 games, only 16 had received a sexual content descriptor" - the survey abstract at the American Medical Association's site has further information on the researchers' results. -
Designer Babies, Version 1.0
Stickerboy writes: "A 30 year-old woman in Chicago gave birth to a pre-pregnancy genetically screened and selected baby 17 months ago, which is being reported in the Journal of the American Medical Association today. Doctors at the Reproductive Genetics Institute in Chicago took 23 eggs from her, screened the eggs for a gene that causes an early form of Alzheimer's, and then fertilized and implanted the eggs back in her womb. Shades of the movie Gattaca - this is a good specific development, but the start of a very controversial trend. Read more about it in the Washington Post or read the abstract in JAMA." -
Scientists No Longer Sharing Information?
chill writes: "A little while back there was an item here on Slashdot about the debate over public funded research and whether or not it should be required to be "open". Well, here is some ammunition to one side of the debate. It seem there is an article in the Chicago Tribune about the increasing unwillingness of genetic researchers to share supporting information with colleagues. The study is from the Journal of the American Medical Association for those who want more than the second-hand summary of the Trib." -
