Authors retract surgery study that claimed to be randomized but wasn’t

spine-coverThe authors of a study about spinal fusion surgery have retracted it after realizing the cohort study was described as a prospective, randomized trial. 

The last author told us he believed the incorrect wording was added to the paper — and the title — by accident. Even though he said the journal Spine suggested correcting it, the authors chose to retract the paper entirely.

The abstract of the study describes the design as a:

Prospective, randomized, controlled trial.

But according to the retraction notice for “Prospective, randomized, controlled trial of silicate-substituted calcium phosphate versus rhBMP-2 in a minimally invasive transforaminal lumbar interbody fusion,” the abstract was not accurate:

Misidentified cell line fells cancer paper

Screen Shot 2016-04-15 at 2.52.06 PMResearchers have retracted a paper about a new molecular target for cancer after realizing they had mistaken the identity of their cell line.

It’s all too easy to mix up cell lines, so we see plenty of retractions for that reason — and, according to an expert in the area, many more cases lurk uncorrected in the literature.

The retraction notice for “Knockdown of tumor protein D52-like 2 induces cell growth inhibition and apoptosis in oral squamous cell carcinoma” in Cell Biology International explains the authors’ perspective on this case:

Environmental group alleges scientific fraud in disputed methane studies

icn-logoNote: We are reprinting below an article originally published at InsideClimate News.

The inspector general of the U.S. Environmental Protection Agency has been asked to examine whether a significant recent study of greenhouse gas emissions from oil and gas fields was technically flawed—and whether researchers brushed aside concerns that methane pollution was being understated.

The emission of methane, a much more potent greenhouse gas in the short term than carbon dioxide, has proven difficult to measure. The latest complaint is a volley in a long-running skirmish among academics, advocacy groups and regulators over how tightly methane should be regulated.

On Wednesday, a North Carolina environmental advocacy group, NC Warn, alleged that this dispute has risen to the level of fraud. Continue reading Environmental group alleges scientific fraud in disputed methane studies

Columbia investigation reveals researcher faked data — and a degree

InnateImmunityA researcher faked data and a masters degree, according to an investigation by Columbia University.

He’s also earned his fourth retraction. The new notice, along with one we’ve uncovered from 2014, provide some information on the extent of the deception of Robert Frumento, who left Columbia a decade ago, around the time that the now-retracted papers were published.

Here’s the new retraction notice:

Author denies accusations of blatant duplication

NPGTwitter is abuzz today over allegations that a recent paper in Scientific Reports contains a blatant example of duplication.

According to the allegations, a group of researchers in Malaysia have used the same four images to represent some 30 cells at different stages of cell death. One researcher has even suggested the allegedly doctored images appear in three different papers.

Is this a manipulated image? See for yourself:

Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Frontiers in PharmacologyAgainst the authors’ wishes, a pharmacology journal has retracted a paper after receiving two messages questioning the “soundness of the experimental results.”

The editors of the journal, Frontiers in Pharmacology, issued an expression of concern about the paper in April 2016, and investigated it following the allegations. According to the retraction notice, the authors disagree with the retraction.

Here’s the retraction notice for the paper: Continue reading Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Three more papers felled by suspected fake reviews

Food Processing and Preservation

So far, we’ve counted more than 300 papers that have been retracted after editors suspected the peer-review process had been compromised — and we’re adding three more to the list.

Editors of the Journal of Food Processing and Preservation became suspicious of the three papers after discovering similarities in reports from supposedly different reviewers. When they were unable to verify the identities of the reviewers, they pulled the papers.

An editor told us that he thinks the reviewer identities were fabricated entirely (as opposed to stolen):

“All co-authors are honorary:” Team earns fifth retraction

Movement DisordersA team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper.

Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed. He and the same co-authors recently lost three other papers about preventing hip fractures for “concerns regarding data integrity” and authorship issues — one of those papers, published in JAMA, specified that Sato was responsible for the data. All four authors were also included in a retraction last year of a paper with “concerns about the underlying data;” there, too, Sato said his co-authors were named “for honorary reasons.”

Here’s the retraction notice for “Alendronate and vitamin D2 for prevention of hip fracture in Parkinson’s disease: A randomized controlled trial,” published in Movement Disorders:

PLOS ONE retracts 2 malaria papers over doubts experiments ever took place

PLOS One

Authors have retracted a pair of PLOS ONE papers after an investigation suggested the articles might contain some fiction.

In the papers, the authors describe collecting and analyzing the DNA of mosquitoes to look for changes following the introduction of bed nets treated with insecticides to combat malaria. However, an investigation by the Institut de Recherche pour le Développement in France could not confirm some of the experiments ever took place.

Here’s the retraction notice for “How the Malaria Vector Anopheles gambiae Adapts to the Use of Insecticide-Treated Nets by African Populations,” which appears at the top of the paper:

Should researchers guilty of misconduct go to “rehab”?

Nature_latest-cover

A report on the first few years of “researcher rehab” suggests that three days of intensive training have a lasting impact on participants.

Specifically, among participants — all of whom had been found guilty of at least one type of misconduct — the authors report that:

A year later, follow-up surveys indicate that the vast majority have changed how they work.

The authors claim this shows the program is worth the time and investment — a $500,000 grant from the National Institutes of Health, and a cost of $3,000 per participant for the three-day course. Do you agree? Tell us what you think in our poll at the end of the story.

Infractions ranged from consent issues for human subjects, plagiarism, and outright fraud. Still, researchers who need this training aren’t much different from everyone else, the authors note in “Lessons of researcher rehab,” published today by Nature: Continue reading Should researchers guilty of misconduct go to “rehab”?
