Authors retract heart disease paper for “nonscientific reason”

Researchers have retracted a 2018 paper about the genetic underpinnings of heart disease from the FASEB Journal — and it’s not entirely clear why.

The paywalled retraction notice simply cites a “nonscientific reason.” Cody Mooneyhan, the director of publications at the journal, declined to provide further details, and the authors have provided different accounts of what happened: The paper’s corresponding author, John Yu, told Retraction Watch that he requested the retraction because the first author, Chia‐Ti Tsai, refused to sign the journal’s copyright agreement. Tsai, a professor in the Department of Internal Medicine at National Taiwan University in Taipei, told us he was “not notified before the paper was submitted.” Continue reading Authors retract heart disease paper for “nonscientific reason”

Child psychiatrist’s research was suspended “indefinitely” following probe

Mani Pavuluri

The University of Illinois at Chicago (UIC) permanently suspended all research activities for a child psychiatrist years ago following an inquiry into her work, Retraction Watch has learned.

In 2015, a UIC spokesperson told us the university had suspended Mani Pavuluri’s clinical research in 2013, after a child in one of her studies had been hospitalized for exhibiting an increase in irritability and aggression. This prompted the university to launch a misconduct probe, and send letters to approximately 350 families of children participating in the research, notifying them of what happened. Now, a spokesperson has informed us that after the institution concluded its probe, it suspended her research “indefinitely.”

Caught Our Notice: 54 problems in three scientific images equals one expression of concern

Title: Effects of microRNA-223 on morphine analgesic tolerance by targeting NLRP3 in a rat model of neuropathic pain

What Caught Our Attention: Usually, an Expression of Concern (EOC) offers general language about “concerns regarding the validity of the data” or “concerns regarding the integrity of the study.” Here the language is anything but, saying that 54 Western blot bands within three figures have problems such as “visible pasted joints,” “square border,” and numerous “appear to be the same band.”  According to the notice, the authors have not responded to requests for the original blots, so the editors are allowing the article to remain intact, choosing instead “to alert readers to these issues and allow them to arrive at their own conclusions regarding the figures.” Continue reading Caught Our Notice: 54 problems in three scientific images equals one expression of concern

Authors retract, replace highly cited paper on ADHD in kids

Researchers have retracted and replaced a 2014 paper in JAMA Psychiatry, exploring a new way to classify attention deficit hyperactivity disorder (ADHD) in children, after discovering errors in the data.

Some experts have criticized the current diagnostic criteria for ADHD—noting, in some cases, it could inflate the rate of diagnosis. Sarah L. Karalunas, the paper’s corresponding author, told Retraction Watch that the aim of the study was to look beyond current criteria and “demonstrate an approach that could be used to better delineate the boundaries of ADHD and other psychiatric diagnostic categories.”   Continue reading Authors retract, replace highly cited paper on ADHD in kids

Highly cited paper by dep’t chair at Sloan Kettering is corrected — three times

A radiology journal has published an addendum to a 2005 review on cancer imaging techniques, alerting readers to figure duplication.

But that’s not what caught our attention about this case. The addendum, published in January, is the third notice that The British Journal of Radiology (BJR) has issued for the 2005 review by Hedvig Hricak, chair of the Department of Radiology at Memorial Sloan Kettering in New York City. The notices, published between 2014 and 2018, all describe duplication.

Why the series of notices, all describing a similar problem? Continue reading Highly cited paper by dep’t chair at Sloan Kettering is corrected — three times

PNAS wouldn’t let authors cite unpublished manuscript. Now, it admits it was wrong.

Question: Do you value Retraction Watch? If so, would you consider a tax-deductible donation of $25, or a recurring donation of an amount of your choosing, to support us?

When researchers submitted a paper about a type of microparticle to PNAS, they wanted to give credit where it was due, and cite an unpublished manuscript that helped guide their work. But the journal’s policy forbid citing unpublished work, and the reference was removed before publication. Now, concerns from the authors of that unpublished work have prompted the journal to have a change of heart.

Paper used to support WHO guidelines on preventing infections “has no scientific validity”

A surgery journal retracted a 2014 paper last month after discovering that the study has “no scientific validity.”

Mario Schietroma and his coauthors, based at the University of L’Aquila in Italy, reported that giving patients high concentrations of oxygen during and after colorectal surgery significantly reduced their risk of infections. Although the authors reported significant p-values, the retraction notice states that, “upon recalculation, no p-values were close to significant.” The University of L’Aquila told Retraction Watch it is investigating, but did not provide details.

Authors claim clinical trial data came from one center. It came from three.

A BMJ journal has retracted a 2017 paper that made a false claim about the clinical trial in question. 

The Acupuncture in Medicine paper reported the results of a clinical trial about the impact of acupuncture and Chinese herbal medicine on stroke, gathered from one center. However, in November, the editors of the journal discovered that the authors had completed the trial at three centers, and had already published the data in Scientific Reports in 2016. The authors say the duplication and misrepresentation of the data stemmed from “confusion and misunderstanding.” Continue reading Authors claim clinical trial data came from one center. It came from three.

Caught Our Notice: Former rising star loses fourth paper

Title: Haemophilus influenzae responds to glucocorticoids used in asthma therapy by modulation of biofilm formation and antibiotic resistance

What Caught Our Attention: This is the fourth retraction for Robert Ryan, formerly a high-profile researcher studying infections that can be deadly in people with lung diseases such as cystic fibrosis. In 2016, the University of Dundee in Scotland determined that Ryan had committed research misconduct, including misrepresenting clinical data and duplicating images in a dozen different publications. (Ryan tried to appeal the decision, then resigned.) The latest retraction cites a few problems with the paper, including uncertainty about the provenance of some data.

According to the notice, the second-to-last author, George A. O’Toole at Dartmouth, disagrees with the text of the notice, not the decision to retract. We contacted O’Toole, who declined to comment.

We received a statement from Ryan about the retraction:

Caught Our Notice: Retraction eight as errors in Wansink paper are “too voluminous” for a correction

Title: Shifts in the Enjoyment of Healthy and Unhealthy Behaviors Affect Short- and Long-Term Postbariatric Weight Loss

What Caught Our Attention: Cornell food marketing researcher Brian Wansink, the one-time media darling who has been dogged by mounting criticism of his findings, has lost another paper to retraction. As we’ve noted in the past, corrections for Wansink’s work tend to be long. This time, “the number of errors is too voluminous to be executed by issuing a correction statement,” according to the retraction notice for a paper about behaviors following weight loss surgery.
