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 Acta Psychiatr Scand 2010;122:454–460 has been retracted.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

Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

The Journal of Agricultural and Food Chemistry has retracted three papers by Dipak Das, the resveratrol researcher found to have committed more than 100 counts of fraud by the University of Connecticut.

Journal editor James Seiber writes: Continue reading Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

Society error leads to published — then retracted — Alzheimer’s abstract from top group

Alzheimer’s & Dementia has retracted a meeting abstract the journal published without the OK of the researchers, a top group from Harvard, who submitted it but withdrew the work before the conference.

That, as they say, might require some unpacking. Maybe this will make things clearer.

Raj Hooli, a graduate student in the lab of Rudolph Tanzi, a leading neuroscientist at Harvard — where he holds the Joseph P. and Rose F. Kennedy endowed chair of neurology — had submitted the abstract, “Genome-wide assessment of copy number variations in early-onset Alzheimer’s disease,” for consideration at the International Conference on Alzheimer’s Disease (ICAD).

As Tanzi explains: Continue reading Society error leads to published — then retracted — Alzheimer’s abstract from top group

Plagiarism leads to seven retractions (and counting) in the conservation literature

Serge Valentin Pangou

An ecology researcher in the Congo has found himself at the center of a plagiarism scandal that has felled seven of his papers.

As Science reports today, Serge Valentin Pangou’s work began unraveling in August 2011 after Wageningen University ecologist Patrick Jansen thought a paper he’d been asked to review for the International Journal of Biodiversity and Conservation seemed familiar — because he’d written many of the same words in a 2007 paper in Conservation Biology. He ran the manuscript through the plagiarism detection software Turnitin, and sure enough, it was about 90% identical.

Unfortunately for Pangou, Jansen’s co-author on the Conservation Biology paper was Pierre-Michel Forget, whose father, as Science notes, “was a well-known private detective in France.” Forget and Jansen took a careful look at a number of Pangou’s papers, Continue reading Plagiarism leads to seven retractions (and counting) in the conservation literature

Journal yanks anemia paper over duplicate data

Blood Cells, Molecules, and Diseases (that’s one title) has retracted a 2011 paper, “Comparative proteomics reveals deficiency of NHE-1 (Slc9a1) in RBCs from the beta-adducin knockout mouse model of hemolytic anemia,” after learning from a reader that the data it contained were previously published by a competing publication.

As the notice explains: Continue reading Journal yanks anemia paper over duplicate data

Neuro journal retracts case study with redundant data

If that headline has you scratching your, well, head, we don’t blame you. After all, case studies are, by definition, unique — but not this one.

Neurological Sciences, the official journal of the Italian Society of Neurology, has retracted a 2009 article by a Korean scientist after learning that the manuscript contained elements of a 2007 publication in a different publication.

According to the notice: Continue reading Neuro journal retracts case study with redundant data

Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons

Bharat B. Aggarwal, the MD Anderson researcher under investigation at his institution over concerns of image manipulation, has withdrawn a second paper, although you’d never know why from the statement.

The notice for the article, “Evidence for the critical roles of NF-κB p65 and specificity proteins in the apoptosis-inducing activity of proteasome inhibitors in leukemia cells,” is pretty minimal: Continue reading Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons

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

Gastro journal retracts duplicate review, but what really happened?

Current Opinion in Gastroenterology is a bimonthly journal “offering a unique and wide ranging perspective on the key developments in the field” that “features hand-picked review articles from our team of expert editors.”

Apparently, those hands picked what amounted to the same “unique” article twice. The journal is retracting a 2004 paper, “Enteral feeding,” by Khursheed Jeejeebhoy, an expert in nutrition at the University of Toronto (he’s now emeritus), because it duplicates a 2003 paper with the same title.

Here’s what the notice, which, lamentably, sits behind a paywall, has to say: Continue reading Gastro journal retracts duplicate review, but what really happened?

Climate science critic Wegman reprimanded by one university committee while another finds no misconduct

The author of a controversial and now-retracted paper questioning the science of climate change has been reprimanded by his university for plagiarism. According to USA Today’s Dan Vergano, who broke the news:

[Edward] Wegman was the senior author of a 2006 report to Congress that criticized climate scientists as excessively collaborative, and found fault with a statistical technique used in two climate studies. Portions of the report analysis were published in the journal, Computational Statistics & Data Analysis, in a 2008 study.

University of Massachusetts professor Raymond Bradley filed a complaint against Wegman in 2010, noting that portions of the report and the CSDA study appeared lifted from one of his textbooks and from other sources, including Wikipedia. CSDA later retracted the study, noting the plagiarism, last year.

Here’s the explicit retraction notice: Continue reading Climate science critic Wegman reprimanded by one university committee while another finds no misconduct
