Research Regarding Infant Deaths Linked To Japan’s Fukushima Meets Controversy

nuclear radiation, reporting on health, fukushima, vicente navarro, michael moyerLast week, I wrote about controversial research linking fallout from Japan’s earthquake-damaged Fukushima nuclear plant to infant deaths in the United States.

The research, which was harshly criticized by Scientific American’s Michael Moyer and others, was published in the peer-reviewed Journal of International Health Services, and I had asked the journal’s editor-in-chief Vicente Navarro for his response to the criticisms.

Navarro, professor of health policy at Johns Hopkins University’s Bloomberg School of Public Health, emailed me this comment today: Read more »

Book Review: “Tabloid Medicine: How The Internet Is Being Used To Hijack Medical Science For Fear And Profit”

This was the Guest Blog at Scientific American on February 23rd, 2011. 

In his new book, “Tabloid Medicine: How The Internet Is Being Used to Hijack Medical Science for Fear and Profit,” Robert Goldberg, PhD, explains why the Internet is a double-edged sword when it comes to health information. On the one hand, the Web can empower people with quality medical information that can help them make informed decisions. On the other hand, the Web is an unfiltered breeding ground for urban legends, fear-mongering and snake oil salesmen.

Goldberg uses case studies to expose the sinister side of health misinformation. Perhaps the most compelling example of a medical “manufactroversy” (defined as a manufactured controversy that is motivated by profit or extreme ideology to intentionally create public confusion about an issue that is not in dispute) is the anti-vaccine movement. Thanks to the efforts of corrupt scientists, personal injury lawyers, self-proclaimed medical experts, and Hollywood starlets, a false link between vaccines and autism has been promoted on a global scale via the Internet. The resulting panic, legal feeding frenzy, money-making alternative medicine sales, and reduction in childhood vaccination rates (causing countless preventable deaths), are sickening and tragic.

As Goldberg continues to explore the hyperbole behind specific “health threats,” a fascinating pattern emerges. Behind the most powerful manufactroversies, lies a predictable formula: First, a new problem is generated by redefining terminology. For example, an autism “epidemic” suddenly exists when a wide range of childhood mental health diagnoses are all reclassified as part of an autism spectrum. The reclassification creates the appearance of a surge in autism cases, and that sets the stage for cause-seeking.

Second, “instant experts” immediately proclaim that they have special insight into the cause. They enjoy the authority and attention that their unique “expertise” brings them and begin to position themselves as a “little guy” crusader against injustice. They also are likely to spin conspiracy theories about government cover-ups or pharmaceutical malfeasance to make their case more appealing to the media. In many cases the experts have a financial incentive in promoting their point of view (they sell treatments or promote their books, for example).

Third, because mainstream media craves David and Goliath stories and always wants to be the first to break news, they often report the information without thorough fact-checking. This results in the phenomenon of “Tabloid Medicine.” Read more »

MRI-Safe Pacemakers Available In U.S. Hospitals Soon: What It Means For Heart Patients

This was the Guest Blog at Scientific American on February 16th, 2011.

New wave of MRI-safe pacemakers set to ship to hospitals

This week Medtronic will begin shipping to hospitals in the United States the first pacemaker approved by the FDA as safe for most MRI scans. For consumers, it is a significant step in what is expected to be a wave of new MRI-compatible implanted cardiac devices.

But this is an example of one technology chasing another and the one being chased, the MRI scanner, is changing and is a step ahead of the new line of pacemakers. The pacemaker approved for U.S. distribution is Medtronic’s first-generation pacemaker with certain limitations, while its second-generation MRI-compatible pacemaker is already in use in Europe where approval for medical devices is not as demanding as it is in the U.S. So let’s check out what this is all about — what it means now for current and future heart patients and where it may be headed.

We are all born with a natural pacemaker that directs our heart to beat 60 to 100 times a minute at rest. The pacemaker is a little mass of muscle fibers the size and shape of an almond known medically as the sinoatrial node located in the right atrium, one of four chambers of the heart. The natural pacemaker can last a lifetime. Or it can become defective. And even if it keeps working normally, some point may not function well along the electrical pathway from the pacemaker to the heart’s ventricles which contract to force blood out to the body.

Millions of people in the world whose hearts beat too fast, too slow, or out of sync because their own pacemaker is not able to do the job right, follow their doctors’ recommendation to get an artificial pacemaker connected to their heart to direct its beating. The battery-run pacemaker in a titanium or titanium alloy case the size of a small cell phone, (why can’t it be the size of an almond?) is implanted in the upper left chest, just under the skin, with one or two insulated wire leads connecting to the heart. It can be programmed to run 24/7 or to only operate when the heart reaches a certain state of irregular beating.

Eat To Save Your Life: Another Half-True Diet Book
