Journal Retracts Gene Therapy/Diabetes Study

A study that claimed gene therapy led to remission of Type 1 diabetes in rats and mice has been retracted by the journal Nature at the request of three of the five authors.

The researchers asked for the retraction because they couldn't reproduce the results of their study, which was published more than eight years ago, said the Associated Press. A fourth author insists the results are still valid and a fifth author is deceased.

In the study, the researchers said they created a gene designed to produce an insulin-like chemical. After the gene was given to rodents with Type 1 diabetes, they no longer suffered from the disease, according to the study. At the time, the researchers said this technique might prove effective in people.

However, after the study was published, diabetes experts told the AP that it wasn't clear the gene therapy would work in humans.

Medical Groups Must Sever Industry Ties: Article

Professional medical groups must "wean" themselves from drug and medical device industry financial support and ties, a group of prominent physicians and researchers write in the April 1 issue of the Journal of the American Medical Association.

They urged medical associations to adopt stricter conflict-of-interest guidelines that go beyond requiring disclosure of financial links to companies. The group also wants medical associations to forbid members who receive industry money from serving in leadership positions and on influential committees, The New York Times reported.

The group also called for a ban on corporate money for things such as souvenir pens, tote bags and sponsorship of committees that develop clinically important guidelines and training programs.

The authors of the article said it would be difficult to achieve these reforms, but such action is necessary if medical groups want to maintain their scientific integrity and the trust of their patients, The Times reported.
