While 23andMe brings down the price of consumer genetic tests and builds up relations with big pharma (doesn’t share individual data though), it seems the DTC genetic testing is neither accurate in predictions nor beneficial to individuals according to a study described on Medical News Today.
Working under the supervision of Associate Professor Cecile Janssens, together with researchers from Leiden, The Netherlands, and Boston, USA, Ms Kalf examined the risk predictions supplied by two large DTC companies, deCODEme (Iceland) and 23andMe (USA). They simulated genotype data for 100,000 individuals based on established genotype frequencies and then used the formulas and risk data provided by the companies to obtain predicted risks for eight common multi-factorial diseases – age-related macular degeneration (AMD), atrial fibrillation, celiac disease, Crohn’s disease, heart attack, prostate cancer, and Type 1 and Type 2 diabetes (T2D).

When I was in medical school at Columbia University College of Physicians and Surgeons, Dr. Mehmet Oz had the reputation of being a competent and caring cardiothoracic surgeon whose research interest was reducing preoperative stress. I remember hearing about a music study of his in which soothing melodies reduced blood pressure and heart rates in patients preparing for heart surgery. I felt pleased that a surgeon was leading the charge in improving patients’ O.R. experiences, and had no inkling that 15 years later Dr. Oz would be America’s chief snake oil salesman.
I have been slow to criticize Dr. Oz on my blog because of a sense of loyalty to my medical school, however yesterday he crossed the line when things got personal – a friend of mine was negatively impacted by his misinformation to the point where her life was endangered. From watching his TV show, she was led to believe that she would put herself at risk for thyroid cancer if she got a mammogram. Several of her relatives have had breast cancer, and she should be particularly vigilant in her screening efforts. However, because Dr. Oz said that mammograms may themselves cause cancer, she opted out of appropriate screening.
But how does the average lay person know how to evaluate Dr. Oz’s health claims? When Oprah’s network promotes him as “America’s physician” the platform itself offers him credibility, and a reach that can damage and misinform millions like my friend. I have a feeling that many of my peers at Columbia are concerned about Dr. Oz’s promotion of quackery, but once they’ve invested in his brand for so long, it’s easier to turn a blind eye to his nuttiness than to oust him from his academic positions. At what point is a celebrity doctor doing more harm than good to an institution’s reputation? Is he now “too big to fail?”
But back to my main point – dear readers if you watch Dr. Oz and think that he’s a credible source of health information, please be aware that much of what he says is inaccurate, exaggerated, and based on mystical belief systems. Please don’t act on his advice without checking with your own physician first.
Sadly, good science doesn’t always make good television. But the truth can make you well. Be warned that you are unlikely to find the truth consistently on the Dr. Oz show.
Going to the Huffington Post for medical information is perhaps comparable to going to Vito Corleone for advice on income tax compliance. Another prominent blogger refers to is as “that hive of scum and quackery,” a lovely and accurate epithet for a media outlet which provides refuge and cover for anti-vaccationists, homeopaths and practictioners of reiki and other such pseudoscientific twaddle. I avoid the HuffPo like the plague. But, like a moth to the flame, sometimes I can’t help myself, and when a facebook friend (and former blogger) pointed to this contrarian article, my interest was piqued and I had to check it out.
First of all, I don’t know Dr Gottfried, and I don’t want to cast aspersions on him professionally. He might be a faith healer and snake-handler, or he might be a prominent researcher and expert in the field. I have no idea, and other than his questionable judgement in being affiliated with the HuffPo, I don’t want to make any judgement on him as a physician or a scientist. Read more »

More and more patients these days are seeing their physician pull out an iPhone or iPad to look up drug dosing information, review lab and radiology data, or help teach them more about their medical condition. And as developers, and the increasing number of physician-developers, continue to find more creative ways to bring medical resources to the point of care, we can certainly expect smartphone platforms and medical apps to become pervasive at the bedside. However, just as healthcare providers and patients are noticing this trend, there are number of others who are paying attention as well – for WebMD, one of the largest companies in this industry, it is the lawyers who may be watching that are worrisome.
As they put it in their annual statement to the SEC,
If our content, or content we obtain from third parties, contains inaccuracies, it is possible that consumers, employees, health plan members or others may sue us for various causes of action.
We’ve talked in the past about potential liability issues for healthcare providers using medical apps and the developers who produce them, as well as similar issues related to electronic health records. The fact that WebMD found the issue significant enough to report it to the SEC and their investors clearly indicates the issue is still unresolved and the remainder of their statement adds some further interesting perspective.

A German physician wrote me about this, so while CNN may have an international reach, it’s not always with an adoring audience.
The physician was reacting to the weekend “Paging Dr. Gupta” program, which Dr. Gupta referred to once as “SG, MD.” The first thing that struck me was his introduction, in which he said:
“I’m your doctor. I’m also your coach.”
Later in the program he said:
“Think of this as your appointment. No waiting. No insurance necessary.”
I find this very troubling. He’s not my doctor. He’s not my coach. When I watch a “news” program, it’s NOT my medical appointment. It’s supposed to be news, not medical advice.
But that’s not what the German physician wrote to me about, so I kept watching (the segment in question appears about 5 minutes and 30 seconds deep, and after the 30-second commercial you have to watch to get there):
Gupta reacted to a viewer’s message on Twitter in which the tweep asked: “Does anyone know a ‘miracle’ treatment for ovarian cancer?” Read more »

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
I met Dr. Marty Makary over lunch at Founding Farmers restaurant in DC about three years ago. We had an animated conversation about hospital safety the potential contribution of checklists to reducing medical errors and his upcoming book about the need for more transparency in the healthcare system.
