Title: Ghanaians Might Be at Risk of Inadequate Dietary Intake of Potassium

What Caught Our Attention: Potassium-rich diets are thought to be “heart-healthy,” and after examining the average dietary habits of Ghanaian adults, researchers determined the average potassium (K) intake to be well below global standards.  However, the authors’ calculations of potassium intake per capita were too low by factor of 10, resulting in the incorrect conclusion that the average potassium intake was only 856 mg per day, an amount substantially lower than the World Health Organization (WHO) recommendation of 3510 mg/day.  The new calculations show an average K intake of 8,560 mg/day, well over the WHO guideline.  

We asked the corresponding author, David Oscar Yawson, about the source of the error, and he responded:

Title: Endotoxaemia during left ventricular assist device insertion: relationship between risk factors and outcome

What Caught Our Attention: Robert J. Frumento first caught our notice in 2013, as a coauthor on a paper retracted with a nonspecific reference to author misconduct.  Three years later, Frumento was clearly identified as having fabricated data and a master’s degree, and added three retractions to his name. Now he’s got a fifth retraction, this one citing missing data and a lack of proof that data blinding was performed correctly.   Continue reading Caught Our Notice: Columbia researcher up to five retractions

Caught Our Notice: A retraction that is “useful for investigators”

Title:  Yeast CAF-1 assembles histone (H3-H4) 2 tetramers prior to DNA deposition

What Caught Our Attention: Informative retraction notices can be infrequent, but rarer still are notices that fulfill an oft-ignored function: To be a source of learning for others in the field. Here, the authors offer a nearly 800-word “detailed description of the issues” with “some observations that may be useful for investigators conducting similar studies.” These authors embraced the retraction process, carefully explaining their findings or the lack thereof, for each figure from their now-retracted paper.     Continue reading Caught Our Notice: A retraction that is “useful for investigators”

Caught Our Notice: How can a publication be a surprise to a corresponding author?

Title: Umbelliferone reverses depression-like behavior in chronic unpredictable mild stress-induced mice via RIP140/NF-κB pathway

What Caught Our Attention: One would think that the corresponding author would have to be aware that they are submitting an article for publication — but apparently not, as this retraction demonstrates. The 2016 paper listed two corresponding authors — along with both of their emails and mailing addresses — but according to the retraction notice, one of them did not give consent “in any form” to the publication. Often, we see authors unaware of the use of their name when their email has been faked, but here, it’s possible the journal simply relied on the other corresponding author for all correspondence.

Title: Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells

What Caught Our Attention: When authors decide they want to make their articles freely available after they’ve already been published, how should publishers indicate the change, if at all? Recently, Ross Mounce (@rmounce) thought it was odd a Springer journal issued a formal correction notice when the authors wanted to make their paper freely available, and we can’t say we disagree.  As he posted on Twitter:

Title: Exploration of inhibitory mechanisms of curcumin in lung cancer metastasis using a miRNA- transcription factor-target gene network

What Caught Our Attention: The researchers were studying how curcumin, a component of the spice turmeric, can inhibit lung cancer metastases. But upon learning that the primary material had been expired at the time of testing (and realizing they were unable to repeat their experiments), the researchers pulled their paper. Expiration dates do have safety factors built in, but attention to such details is imperative in research.  Continue reading Caught Our Notice: What if you find out a paper relied on expired herbal supplement?

Title: Molecular Characterization and Biological Activity of Interferon-α in Indian Peafowl (Pavo cristatus)

What Caught Our Attention: Soon after the paper appeared, the journal was alerted to the fact its findings were at odds with others in the field. When the editor approached the authors, everything fell apart: The authors couldn’t repeat the experiments, and “were also unsure of the molecular probes that were used in the study.” While it isn’t unusual to have doubts about data — since since research is a process of experimentation — it is odd not to know how your experiment was conducted. The paper was retracted less than two months after it was published. The manuscript was accepted two months after it was submitted in early May, theoretically giving reviewers enough time to catch these issues (along with the authors’ failure to cite relevant papers).

TitleChange Their Choice! Changing Behavior Using the CAN Approach and Activism Research

What Caught Our Attention: Food researcher Brian Wansink has had a rough time lately. After researchers began scrutinizing his work, he has racked up five retractions and multiple corrections. (We’re counting one retracted paper twice, as Wansink first retracted and replaced it with a new version, then retracted the replacement.)

These notices haven’t gone unnoticed, either by us or other media outlets — BuzzFeed reported on his most recent retraction this weekend, a paper a critic discussed with us, as well. Yesterday, BuzzFeed also reported that Cornell is investigating. (It wouldn’t be the first time — in April, Cornell announced that it had found evidence of mistakes, not misconduct, in Wansink’s papers.)  Below, we present his 13th correction, for duplicated text — 1,376 words of duplicated text, to be exact.

Title: Hepatitis B Virus Infection in Preconception Period Among Women of Reproductive Age in Rural China – A Nationwide Study

What Caught Our Attention: When researchers set out to study hepatitis B among women in rural China, and they wanted to know if the women had been vaccinated against the virus, they simply asked them. While that can sometimes be useful, apparently it was a mistake in this case, as the reliance on patient memory injected too much doubt into these findings.  Continue reading Caught Our Notice: To know if someone’s been vaccinated, just asking isn’t enough

Title: IRF9 inhibits human acute myeloid leukemia through the SIRT1-p53 signaling pathway

What Caught Our Attention: When authors fail to respond to editors’ requests for information, it isn’t hard to imagine that the submitted manuscript will lose its publishing appeal. In this case, the journal and publisher withdrew the article after “repeated attempts” to contact the authors were unsuccessful.

The notice doesn’t say why the journal needed to get in touch with the authors; of course, some authors may cease correspondence for a variety of reasons, but there is usually some backstory. Since the authors disappeared, the withdrawn article has, as well. Continue reading Caught Our Notice: When authors go MIA, the article may follow
