The authors of a study allegedly showing that antidepressants prevent suicide have retracted it over unspecified errors. Here’s the notice:
At the request of the authors and in agreement with the Editor-in-Chief and Wiley-Blackwell, the following article “Antidepressant medication prevents suicide in depression”. Acta Psychiatr Scand 2010;122:454–460 has been retracted. The retraction has been requested and agreed due to unintentional errors in the analysis of the data presented.
When a group from Saint Louis University published a case report in Pediatric Transplantation on a baby with an unusual infection after kidney transplant surgery, they thought they’d stumbled on a first. At the time they wrote:
[Acalculous candidal cholecystitis] caused by Candida is an uncommon entity usually seen in the critically ill. Here, we present the case of an 18-month-old renal transplant patient who developed candidal AAC during the post-operative period. Previous articles have addressed acalculous cholecystitis secondary to a variety of causes, or addressed a wide variety of Candida infections in the biliary tract, but this is the first discussion of cholecystitis caused by Candida without confounding factors such as biliary calculi or multiple pathogens. After the discussion of our patient’s case, we also reviewed the English-language literature regarding candidal AAC and discussed diagnosis, treatment, and mortality.
A year later, however, the group is walking back their article. A retraction notice in the journal states that: Continue reading On second thought: Transplant paper retracted for researcher error
Last month, we wrote about the retraction of a 2005 paper suggesting that some adult stem cells might give rise to cancer. That, of course, would be a problem if researchers tried treating heart disease and other conditions with them. The paper’s authors retracted it, however, when it became clear that instead of being transformed — that’s the scientific word for “became cancerous” — the cells had simply become contaminated and overgrown with tumor cells used in research.
We had some questions for the authors of the original paper, and for the editor of the journal. Last week, we heard back from one of the paper’s authors, Javier Garcia-Castro, who had been on vacation without Internet access for weeks. In an email to Retraction Watch, Garcia-Castro wrote: Continue reading Update on stem cell-cancer link retraction: Why not everyone signed, and why authors ended up in another journal first
