Patients did not okay publishing brain surgery details

Screen Shot 2016-05-03 at 2.37.02 PM

BioMed Central has retracted a paper after realizing it shared details on the brain surgeries of four patients without their consent.

Darlene Lobel, a neurosurgeon at the Cleveland Clinic in Ohio, agreed to the retraction, and told us she didn’t know that she needed consent from the patients since all identifying details had been removed. The paper describes a technique for craniotomy — opening up the skull to access the brain — and included CT scans of hemorrhaging and swelling that the patients experienced, as well as other details such as their gender and age.

Here’s the retraction notice:

Unwitting co-author requests retraction of melatonin paper

Screen Shot 2016-06-08 at 10.54.58 PMNine years ago, a well-known pharmacologist hosted a researcher from another university in his lab. On a Saturday night last September, he learned while surfing Google Scholar that they had published a paper together.

Marco Cosentino, who works at the University of Insubria in Italy, know that Seema Rai, a zoologist at Guru Ghasidas Vishwavidyalaya in India, had collected data during during her six months in his lab, but had warned her they were too preliminary to publish. She published the data — on melatonin’s role in immunity — anyway, last summer in the Journal of Clinical & Cellular Immunology, listing Cosentino as the second author.

The day after he discovered the paper, Cosentino sent an email to the editor in chief of the journal, Charles Malemud, explaining why he did not approve of the publication:

“We were completely shocked:” Plant biologists issue mega-correction

Plant Cell cover

Plant biologists have issued a major correction (what we dub “mega“) after realizing a significant mistake in their experiment.

The 2014 paper shows that a protein known as RAP plays a key role in chloroplast biogenesis. But as Ludwig Maximilians University-based authors Alexandra-Viola Bohne and Laura Kleinknecht continued to do their research, they found an error in the design of primers they used to synthesize the RNA for their experiments — and told us they are concerned other researchers could run into the same problem.

Although the authors considered retracting the paper, since its main conclusion was unaffected, they issued a correction notice, published in April in Plant Cell:

Here’s why this lawyer defends scientists accused of misconduct

Paul S. Thaler
Paul S. Thaler

More scientists are trying to settle accusations of misconduct in court, a trend very familiar to Washington, DC-based lawyer Paul Thaler. Regular readers may recall the name of one of Thaler’s clients — Rakesh Kumar, a scientist at George Washington University who filed an $8 million lawsuit for how the school handled an investigation into his work. He’s also representing Bharat Aggarwal, the subject of an investigation at MD Anderson who has threatened to sue us (and logged his ninth retraction this week). For 25 years, Thaler has been representing scientists embroiled in misconduct proceedings. He spoke to us about his family’s highly pedigreed background in science, and why everyone deserves an advocate.  

Some of your clients have committed misconduct, but you still work to protect their reputations and even help them continue to do research. Why?

HIV paper pulled for lack of consent, errors

AIDS JournalA researcher failed to obtain proper consent from HIV patients included in his study about risky sexual behavior, according to the journal that retracted his paper.

The study, based on interviews with 154 men and women living with HIV, concluded that experiencing negative life events correlated with risky sexual behavior. But although the author claimed to have complied with the journal’s standard of consent, the journal disagreed, and retracted the paper in 2014 (we think this case is interesting enough to share with you now). What’s more, according to the journal, the paper contains errors that invalidate its conclusions.

Here’s the notice:

Two journals retracting papers from University of Malaya featuring widely criticized figures

The image that excited twitter: Figure 6 from the Scientific Reports paper
The image that excited Twitter

One journal has retracted a paper containing images that recently raised suspicions of obvious duplications, and another journal is planning to do the same.

Scientists first leveled accusations against the newly retracted paper in Scientific Reports, along with two others by the same researchers, earlier this month on Twitter. One other journal — PeerJ — has announced that it plans to retract one of the questioned papers, as well. The third paper, in Frontiers in Pharmacology, bears an expression of concern.

It was unusually quick action on the part of the journals, as well as the authors’ host institution, the University of Malaya, which announced last week the authors had manipulated figures in all three papers, along with one other.

Here’s today’s retraction notice from Scientific Reports for “Novel piperazine core compound induces death in human liver cancer cells: possible pharmacological properties:”

Journal flags paper over allegations it used competitors’ text, plasmids

MGGA journal has issued an expression of concern (EOC) for a paper on a common crop virus after the authors were accused of using competitors’ unpublished text and plasmids.

Investigations by the journal and the involved institutions — the University of the Witwatersrand in South Africa, where the paper’s authors are based, and North Carolina State University (presumably, where the accusing group is from) — were inconclusive, the notice states.

So the editor flagged “Sequences enhancing cassava mosaic disease symptoms occur in the cassava genome and are associated with South African cassava mosaic virus infection” with an EOC:

Dental paper pulled for “wrong content with serious consequences”

Clinical Oral InvestigationsAn article on how missing teeth affect chewing was — well, pulled — when someone noticed a few errors. The journal later published a corrected version.

The retraction for “Chewing ability in an adult Chinese population” appeared in Clinical Oral Investigations in 2012, but we’re sharing it with you now because the notice contains some remarkable language:

This article has been withdrawn due to wrong content with serious consequences such as danger to people’s health.

Last author Nico H.J. Creugers, who works at Radboud University Medical Center in the Netherlands, told us:

JAMA authors retract (and replace) paper about moves and kids’ mental health

JAMAJAMA authors have retracted — and replaced — a 2014 paper about the mental health effects of household moves on kids, after they found errors while completing an additional analysis.

The original paper concluded that in “families who moved out of high-poverty neighborhoods, boys experienced an increase and girls a decrease in rates of depression and conduct disorder,” according to a press release issued by the journal along with the paper (which also got some press attention from Reuters). But part of that conclusion is wrong.

The authors write in a notice for “Associations of Housing Mobility Interventions for Children in High-Poverty Neighborhoods With Subsequent Mental Disorders During Adolescence” that:

Researcher suing PubPeer commenters earns 5 retractions following investigation

Fazlul Sarkar

An investigation at Wayne State University has prompted five retractions for a scientist who is suing PubPeer commenters after they criticized his work on the site.

The investigation into Fazlul Sarkar and his co-authors found that the papers contain images that were “inappropriately manipulated” or “inappropriately re-used and re-labeled.” All five retraction notices are from the Journal of Cellular Biochemistry.

Here’s the retraction notice for “Concurrent inhibition of NF-κB, cyclooxygenase-2, and epidermal growth factor receptor leads to greater anti-tumor activity in pancreatic cancer:
