Hmmm: SAGE’s attorney explains why weight loss retraction notices said less than those of other journals

In May, we broke the story of Edward Shang, a weight loss surgeon who made up most, if not all, of the patients he reported on in at least one study. We’ve been following the case since then, including three more retractions in the Journal of Parenteral and Enteral Nutrition (JPEN).

As we noted in a June 22 post, the notices in JPEN were a bit more lean than the first notice we found, in Surgery for Obesity and Related Diseases. The latter read: Continue reading Hmmm: SAGE’s attorney explains why weight loss retraction notices said less than those of other journals

Another retraction for grad student who specializes in plagiarism and forging co-authors’ names

We have an update on the case of Moêz Smiri, a graduate student working in a Tunisian-French laboratory, whose bold method of bulking up his CV  proved a bit trop ambitieux. 

As we reported back in August 2011, Smiri had plagiarized repeatedly from previously-published work, and forged the names of co-authors, in a 2010 article in Plant Science on the effects of cadmium on peas. That article was one of at least six papers on which Smiri appeared as first author — a pretty impressive output for a young researcher.

Among the list was article in Ecotoxicology and Environmental Safety, “Effect of cadmium on resumption of respiration in cotyledons of germinating pea seeds.” That paper is now retracted. According to the notice: Continue reading Another retraction for grad student who specializes in plagiarism and forging co-authors’ names

USA Today posts story on approval of diet drug too soon, takes it down

USA Today has yanked back a story about a diet drug’s approval by the FDA — because the FDA hasn’t actually approved the drug yet.

The FDA is scheduled to announce its decision on the subject of the story — Vivus’ Qnexa — today. The decision has been closely watched.

The story, headlined “New diet drug helps heavy patients lose 10% of weight,” includes a lot of reporting, including comments from the president of Vivus about a change in name from Qnexa to something else. (We’ll leave USA Today that apparent scoop, although others might not.) It was posted on the Salem, Oregon’s Statesman Journal at 12:16 p.m. today, presumably Eastern, since it was taken down before the West Coast arrived at 2 p.m. Continue reading USA Today posts story on approval of diet drug too soon, takes it down

Three papers by German management prof retracted for duplication, statistical issues

Ulrich Lichtenthaler, a management professor in Germany, has had three papers retracted by two different journals, after readers noticed statistical irregularities.

Lichtenthaler was at the WHU – Otto Beisheim School of Management when he published the papers in 2009 and 2010. He is now at the University of Mannheim. The retraction in Strategic Organization was first reported by the Strategy Profs blog. It reads: Continue reading Three papers by German management prof retracted for duplication, statistical issues

Primate journal cites duplication in erratum, but does not retract

The International Journal of Primatology has a commendably open notice this month about a 2012 paper on the dietary habits of monkeys — “Western Purple-faced Langurs (Semnopithecus vetulus nestor) Feed on Ripe and Ripening Fruits in Human-modified Environments in Sri Lanka” — with echoes of a 2007 article by the same Sri Lankan researcher: Continue reading Primate journal cites duplication in erratum, but does not retract

How can institutions prevent scientific misconduct?

There has been plenty of interest in scientific fraud and misconduct lately — and not just on Retraction Watch — from major news outlets and government agencies, among other parties. The rate of retractions is increasing, and some fraudsters are even setting new records. That has focused attention on how institutions can prevent misconduct — not something anyone thinks is easy to do.

To try to figure it out, Columbia University’s Donald Kornfeld decided to review 146 U.S. Office of Research Integrity (ORI) cases from 1992 to 2003, “based on 50 years of clinical experience in psychiatry and 19 years as the chairman of two institutional review boards.” (Of note, these only represent cases in which ORI concluded there was misconduct, as the agency doesn’t report on negative cases.) Here’s what he found, reported last month in Academic Medicine: Continue reading How can institutions prevent scientific misconduct?

Group retracts microRNA paper after realizing reagent was skewing results

A retraction from a high-profile group uncovered a technical limitation involving a widely used reagent.

Some quick background: the sequence hypothesis central hypothesis dogma of biology states that DNA gets transcribed to RNA that gets translated into proteins. Some RNAs, however, don’t code for proteins, but instead help to regulate gene expression. These microRNAs are tiny in size, but can regulate gene expression across animal and plant kingdoms.

In September 2011, the Molecular Cell published an entire issue with regulatory RNA as its theme. V. Narry Kim, associate professor at Seoul National University and high-profile microRNA researcher contributed a study that her group has now retracted just months later on June 29.

The problem? A reagent used to purify miRNAs favors some miRNAs and fails to isolate those rich low in guanine and cytosine — two of the four building blocks of RNA — or those with few secondary folding structures.

University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

A second psychology researcher has resigned after statistical scrutiny of his papers by another psychologist revealed data that was too good to be true.

Ed Yong, writing in Nature, reports that Lawrence Sanna, most recently of the University of Michigan, left his post at the end of May. That was several months after Uri Simonsohn, a University of Pennsylvania psychology researcher, presented Sanna, his co-authors, and Sanna’s former institution, the University of North Carolina, Chapel Hill, with evidence of “odd statistical patterns.”

Simonsohn is the researcher who also forced an investigation into the work of Dirk Smeesters, who resigned last month. Last week, Yong reported that Simonsohn had uncovered another case that hadn’t been made official yet.

According to today’s story, Sanna has asked the editor of the Journal of Experimental Social Psychology — which is also retracting one of Smeesters’ papers — to retract three papers published from 2009 to 2011. These are the three he seems to have published there during that time: Continue reading University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

Plagiarism leads to retraction of liver cancer paper

The journal Digestion has a retraction notice that’s, well, an amusing morsel.

At issue was a 2011 paper on a biomarker for liver cancer by a group of Turkish authors who plagiarized from the work of others.

Here’s the notice for the article, titled “Diagnostic and Prognostic Validity of Golgi Protein 73 in Hepatocellular Carcinoma“: Continue reading Plagiarism leads to retraction of liver cancer paper

Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

Note to authors: If a journal asks you to suggest reviewers for your submitted manuscript, don’t thank them by faking the reviewer’s emails.

You might just get caught.

That’s what happened recently at Experimental Parasitology, according to the retraction notice for “Entamoeba histolytica: Cloning, expression and evaluation of the efficacy of a recombinant amebiasis cysteine proteinase gene (ACP1) antigen in minipig:” Continue reading Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses
