Researchers pull Nature paper over first author’s objections

Researchers have retracted a 2015 Nature paper about the molecular underpinnings of immune function after discovering they could not replicate key parts of the results.

The first author, Wendy Huang — who started working as an assistant professor at the University of California, San Diego, only months after the paper appeared — did not sign the retraction letter, published last week. The research was conducted while Huang was working as a postdoctoral fellow at New York University, home of last author Dan Littman (also an investigator at the Howard Hughes Medical Institute).

What happened appears to be a case of “he said, she said:” Littman asked to retract the paper after his lab couldn’t reproduce it, and Huang insists the data remain correct, saying the process had been “unfair and done without due process:”

An author says his work should be “widely heralded and promoted.” So he published it 3 times.

Barislav Momčilović thinks that iodine status is — after iron deficiency — the “main public health” issue in the world today. So when he figured out what he believed was the best way to test levels of the mineral, he was determined to get the message out.

A little too determined, perhaps: He published the same information three times. And one journal caught on.  Last week, Thyroid retracted “Hair Iodine for Human Iodine Status Assessment,” a 2014 paper that they say overlapped with two earlier works.

While publishing duplicate work is considered by some to be just a violation of restrictive publisher copyright agreements, the presence of such duplicates in the literature can bias systematic reviews and other attempts to describe the state of the evidence in a given field. In a retraction notice, Thyroid noted that this was a case of Continue reading An author says his work should be “widely heralded and promoted.” So he published it 3 times.

After probe, journal removes flag from four papers, corrects manipulated images

Last year, Journal of Cell Science added notices to four papers after a reader contacted the editors with some concerns about issues with the figures. Now, it’s replacing the previous editorial notices with corrections, which address duplicated images and data.

When the journal issued expressions of concern for four papers co-authored by José Ignacio Rodriguez-Crespo about the allegations (which had also been raised on PubPeer), it notified his institution, the Universidad Complutense de Madrid (UCM). The newly issued correction notices explain that UCM investigated the four papers, and the data support the results and conclusions. In two cases, the authors supplied the original data, and in the others, they replicated the experiments.

Rodriguez-Crespo declined to comment, saying only that the journal

A journal decided to correct, rather than retract, a paper that contained “potentially contentious advice.” Do you agree with their call?

In March, a journal published a paper about blood sugar levels in newborns that caused an immediate outcry from outside experts, who were concerned it contained a sentence that could be potentially harmful if misinterpreted by doctors.

Recently, the journal explained — in impressive detail — why it’s not retracting the paper. That, of course, gives readers the ability to form their own opinions. After seeing the pros and cons, let us know if you think the journal made the right call in a poll at the bottom of the story.

When it first appeared, the paper — “Newborn plasma glucose concentration nadirs by gestational-age group,” published by Neonatology — included this sentence in its abstract:

In order to potentially prevent low glucose concentrations at the time of the nadir, exogenous glucose should be provided to all newborns as soon as possible after birth.

According to an editorial note published by the journal’s editors, that caused immediate concern for outside experts:

Fecal transplant paper pulled for “personal issue”

Last month, the Journal of Pediatric Gastroenterology and Nutrition pulled an article on fecal transplantation for a reason that, well, doesn’t pass the sniff test.

The paper, by Sonia Michail of Children’s Hospital Los Angeles, appeared online in October 2017 and described a randomized controlled trial of fecal transplants to treat kids with ulcerative colitis. (If you’re interested, here’s an overview of how fecal transplantation works.) The trial, or one awfully like it, is listed on ClinicalTrials.gov, and shows Michail as the lone investigator on the study, which is aiming to gather more than 100 participants.

But the journal retracted the article — which was the subject of a laudatory editorial in the journal pointing readers to the findings — with an entirely opaque statement, saying that the work

Journal holds firm on decision not to retract Macchiarini paper, despite outside pressure

Earlier this year, the president of the Karolinska Institute, Ole Petter Ottersen, contacted the journal Respiration, saying KI had conducted an investigation and determined that a 2015 paper co-authored by once-lauded surgeon Paolo Macchiarini had been tainted by misconduct. Please retract the paper, Ottersen said. When the journal said no — opting to publish correspondence from KI and the authors’ response instead — Ottersen posted some of their correspondence online, in an attempt to pressure the journal to do the right thing. It’s not going to work, according to Thomas H. Nold, publication manager at Karger, which publishes Respiration. We spoke to Nold about the journal’s plans for the paper.

Retraction Watch: How do you feel about KI’s decision to publish your correspondence?

An awkward correction later, these researchers have a warning for would-be authors

Mitchell Knutson

Mitchell Knutson learned to take a journal’s policies seriously the hard way.

Early in 2017, Knutson, a professor at the University of Florida in Gainesville who studies iron metabolism, had findings he and his team were excited about publishing in the Proceedings of the National Academy of Sciences (PNAS). So they submitted a manuscript on January 30. Continue reading An awkward correction later, these researchers have a warning for would-be authors

Does the Mediterranean diet prevent heart attacks? NEJM retracts (and replaces) high-profile paper

The New England Journal of Medicine has retracted a 2013 paper that provided some proof that the Mediterranean diet can directly prevent heart attacks, stroke, and other cardiovascular problems.

The original paper, “Primary Prevention of Cardiovascular Disease with a Mediterranean Diet,” has been cited 1,759 times, according to Clarivate Analytics’ Web of Science.

But the findings haven’t disappeared — the authors have replaced the paper with a new version, which softens its earlier claims. Continue reading Does the Mediterranean diet prevent heart attacks? NEJM retracts (and replaces) high-profile paper

Have you seen more detail in PLOS ONE retraction notices? You’re welcome

If you’ve been pausing at some detailed PLOS ONE notices lately — such as one issued last month for a cancer paper that lists 21 shortcomings — you’re not alone.

According to a spokesperson for the publisher, the journal has been progressively pushing towards more transparency in its notices — in part, because it was getting too many calls from our reporters, asking about details that weren’t in the notice but that were “easily answerable.” This isn’t the first time we’ve seen a journal become more transparent following these kinds of questions — the Journal of Biological Chemistry, for instance, has become much more informative in its retraction notice, following criticism for its previous opacity.

Both the spokesperson and editor Joerg Heber, who took the role in November 2016, were quick to clarify that the increase in detail of notices is not only due to our queries — instead, it’s meant to benefit the entire scientific community. According to the spokesperson:

Journals flag two papers by prominent researcher — who is also on trial for domestic abuse

Adeel Safdar was once a rising star in the field of kinesiology. After completing his doctorate degree at McMaster University in Canada, working with one of the titans of his field, Safdar took a postdoc at Harvard, then accepted a newly created chair position at another university in Ontario.

That all came crashing down last year, when Safdar went on trial in Canada, accused of horrifically abusing his wife. Over the course of the trial, allegations arose about his research, prompting two journals to flag papers he co-authored with his former mentor, Mark Tarnopolsky.

Tarnopolsky — author of more than 400 papers, which have collectively been cited more than 17,000 times, according to Clarivate Analytics’ Web of Science — told Retraction Watch:
