Integrating genome and epigenome studies

The Key Role of Epigenetics in Human Disease Prevention and Mitigation

I've said it many times: beware of snake-oil sellers. Nowadays you may find it everywhere, specially on internet. You may get a genetic test for a disease that creates a false illusion of safety, or another that provides an unnecessary and avoidable concern. Only evidence based prescribed tests can be considered appropriate.
Therefore, if you want to confirm that genome is not enough, you have to check the review at NEJM on epigenetics. At the end of the article you'll find the explanation on why we do need integrated genome and epigenome association studies. You'll understand that cancer is fundamentally an epigenetic disease.
The current knowledge is changing quickly some conventional truths and "known unknowns" that we've had for years. This is good news for citizens, and bad news for snake-oil sellers if detected. Governments should help citizens on this screening effort, and protect citizens from fake medical information.

Practice makes perfect (2)

The Volume–Outcome Relationship Revisited: Practice Indeed Makes Perfect

Why is it so difficult to accept it? There is wide "evidence for the practice-makes-perfect hypothesis by showing that volume is a driving factor for quality". Unfortunately, the opportunities for the health system are still larger than it should be. There is a resistance in organizations, there is inertia, and all these drivers play a role. In planned health systems, there is no reason to be strict on it.
Just for those that are dubious, I would suggest a look at this article and to my former post.

The smart money in tech would not have made this mistake

It's about Theranos. You may find my previous posts in this link. Now SEC has confirmed that was a "massive fraud". That's it. If you want a good analysis check FT.
Microfluidics is not an easy prêt-à-porter technology. Many people knew it but Mrs Holmes has been selling it as snake-oil. And as usual in these cases, the end of the film is already written. She can't go to the lab for the next 10 years, a fine, and the company may be closed. All started with and article by Mathew Herper in WSJ. An innocent article with an innocent question that she couldn't answer. That's all. Silicon valley smart money would not have made this mistake.
