Rheumatology retracts lupus-cancer meta-analysis over multiple errors

Rheumatology has retracted a 2011 paper with too many errors to correct.

According to the notice, the article, titled “Meta-analysis of systemic lupus erythematosus and the risk of cervical neoplasia’, by Hongli Liu and colleagues at Huazhong University of Science and Technology in China, seems to have been deeply flawed: Continue reading Rheumatology retracts lupus-cancer meta-analysis over multiple errors

Paper linking vitamin C and reduced asthma retracted after authors find “severe” problems with data

It’s never a good sign when a paper has “severe” problems with its data. But when even the researchers are at a loss to explain how those problems made their way into the manuscript, well, that’s downright alarming.

Consider: The journal Clinical and Translational Allergy has retracted a 2011 article by researchers from Egypt and Finland, who have been studying the effects of vitamin C on childhood asthma. In a previous article, published in 2009 in Acta Paediatrica, members of the team reported that Continue reading Paper linking vitamin C and reduced asthma retracted after authors find “severe” problems with data

Authors retract paper claiming antidepressants prevent suicide

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 Acta Psychiatr Scand 2010;122:454–460 has been retracted.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.

The original paper linked “data on the toxicological detection of antidepressants in 18 922 suicides in Sweden 1992–2003” to “registers of psychiatric hospitalization as well as registers with sociodemographic data.” It found: Continue reading Authors retract paper claiming antidepressants prevent suicide

On second thought: Transplant paper retracted for researcher error

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

Update on stem cell-cancer link retraction: Why not everyone signed, and why authors ended up in another journal first

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
