“We made big mistakes:” Gastric paper pulled with unusual notice

without comments

Sometimes we come across a real head-scratcher.

That happened this week, when we saw a retraction notice for a 2015 paper on gastric cancer in the International Journal of Clinical and Experimental Medicine, which only says the authors “made big mistakes” and contains two fairly significant typos.

Although there’s no sign of a retraction on PubMed, the table of contents for the latest issue of the journal lists the retraction — but includes no hyperlink to the notice. The only way to see it is via a Web cached version. Here’s the text:

Authors retract two statin papers, one with problems “too extensive to revise”

without comments

Researchers in China have retracted two 2016 papers about the possible use of a cholesterol-lowering agent to treat bleeding on the brain.

One of the retracted papers in the Journal of Neurosurgery (JNS) had multiple problems that were “too extensive to revise,” according to the lengthy retraction notice, relating to issues with authorship, data analyses, and patient enrollment. The notice is signed by first author Hua Liu of the Nanjing Medical University in China.

Liu is also the first author of another recently retracted paper in Frontiers in Neuroscience, pulled for incorrectly categorizing patients.

Journal retracts gastric cancer study with multiple duplications, authors MIA

with 3 comments

An oncology journal has decided to retract a 2012 paper on gastric cancer after discovering duplicated data in multiple figures.

According to the retraction notice, the journal’s editorial board received a tip from a reader regarding the potential figure issues. Oncology Reports launched an investigation, which confirmed the allegations. The authors failed to respond to the journal’s multiple requests for more information.

Authors use same images in two studies — one is retracted, the other flagged by journal

without comments

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern. 

According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”

Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.

Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.

Journal cleans the house by retracting 6 cancer papers for plagiarism

with 3 comments

Following an investigation, a genetics journal has pulled six cancer papers published this year for plagiarizing from other sources.

According to an excerpt from the retraction notice in Genetics and Molecular Research, the journal has “strong reason to believe that the peer review process was [a] failure,” and has alerted the authors’ institutions.

The notice announcing the retraction of all six papers begins: Read the rest of this entry »

Journal issues three notices for plant biologist, two citing manipulation

without comments

Researchers have retracted a paper from a plant journal after a probe found problems with several figures.

According to the new retraction notice in The Plant Cell, some figures in the paper were manipulated, as well as “inappropriately duplicated and reused from a previous publication.” The authors assert that they believe the conclusions remain valid.

The journal has also issued two corrections that include some of the same authors — including one that cites inappropriate image manipulation.

Here’s the retraction notice, issued last month: Read the rest of this entry »

Oops: Supposedly untreated cancer patients had surgery, after all

with one comment

gmrThe first author of a 2016 paper has retracted it after realizing that all the lung cancer patients that were supposed to have been untreated did, in fact, have surgery to remove their tumors. 

Zhao Kai, the study’s first author from the Qilu Hospital of Shandong University and Zibo Central Hospital (both in China), took full responsibility for the error.

Here’s the retraction notice, published last month in Genetics and Molecular Research: Read the rest of this entry »

Journal pulls cancer paper that used others’ data; authors MIA

without comments

A journal has retracted a paper after a reader pointed out some of the data looked familiar — and the authors never responded to the allegations.

According to the retraction notice in the International Journal of Molecular Medicine, the reader showed the journal that the histological data in two of the figures were from another published paper by different researchers. But when the journal contacted the authors on several occasions, they didn’t hear back. 

Here’s the retraction notice: Read the rest of this entry »

Entomology journal retracts 2016 study with flawed analyses

with one comment

journal-of-medical-entomologyAn entomology journal has issued its first retraction during the current editor’s nearly 30-year tenure — for a 2016 study with serious flaws in the analyses. 

After the Journal of Medical Entomology (JME) published the study — about the identification of genes that enable an insect to detect odors — an outside researcher wrote a letter to the journal highlighting flaws in the paper. The journal then asked the authors to respond, and enlisted two additional peer reviewers to look into the study, the outside comment, and the authors’ response. They concluded the paper should be retracted.

William Reisen — the journal’s editor-in-chief from the University of California, Davis — said the journal believes the errors were unintentional and there was no fraud on the authors’ part. He added: Read the rest of this entry »

A first for us: Journal retracts obituary (but not for the reasons you think)

with one comment

journalofdigestivediseasesOn December 31st 2014, a pioneer in the study of inflammatory bowel disease passed away. An obituary published in the Journal of Digestive Diseases shortly thereafter is typical enough: It describes his achievements, importance to his patients, and battle with pancreatic cancer.

But “Loss in the Last Day of 2014: a Eulogy for Prof. Bing Xia” has now been retracted.

This is the first time we’ve seen an obituary pulled from a journal. Unfortunately, this was not a case of a premature obituary (which happens more often than you’d think)– the researcher did actually die, but it appears the journal published the obituary in the wrong place.

The retraction notice, published earlier this year, explains:
