Philadelphia-area lung researcher up to six retractions

A lung researcher is up to six retractions for problematic images.

Dilip Shah’s last academic post was at Cooper University Hospital in Camden, N.J., where he worked as a post-doc in the lab of Vineet Bhandari. While there, Shah landed first authorship on a 2020 article in the European Respiratory Journal titled “miR-184 mediates hyperoxia-induced injury by targeting cell death and angiogenesis signalling pathways in the developing lung.”

University recommends seven more retractions for psychology researcher

Two years after a psychology researcher in The Netherlands was found guilty of misconduct, including manipulating data and cutting co-workers out of publications, a new report says she deserves more retractions.

In November 2019, as we reported, Lorenza Colzato was found guilty by an investigation at Leiden University of having failed to obtain ethics ethics approval for some of her studies, manipulating her data and fabricating results in grant applications.

At the time, the institution – which Colzato had left for TU Dresden – called for the retraction of two of the researcher’s papers. Both were pulled, and we spoke to the three whistleblowers about lessons of the case.

However, the Leiden University weekly newspaper Mare has learned that a subsequent inquiry – a report on which appeared without announcement in November 2021– concluded that 15 of Colzato’s articles appeared to contain evidence of misconduct:

Two abstracts about unapproved heart technology retracted

A group of heart researchers have lost two meeting abstracts after, according to one of the authors, companies said the data were proprietary and couldn’t be published. But it’s not clear the companies did so.

The studies appeared in the journal Heart Rhythm, the official journal of the Heart Rhythm Society, and were presented at the group’s 2021 annual meeting.

The first author on both abstracts was Andrea Natale, a cardiac electrophysiologist at the Texas Cardiac Arrhythmia Institute at St. David’s Medical Center in Austin. We wrote about Natale in 2016, after the researcher lost a paper in the Journal of the American College of Cardiology – again based on work he presented at the Heart Rhythm Society conference about which he raised concerns over industry meddling. (Natale disputes that he was the first author on the now-retracted posters, for reasons that aren’t clear to us.)

Exclusive: How a researcher faked data and gaslit a labmate for years

Sometime in early 2019, a postdoc in a veterinary microbiology lab at Washington State University (WSU) in Pullman came to suspect that a research assistant in her lab was fabricating data.

The postdoc had noticed that the research assistant’s experiments always produced positive results, while hers were always negative. And the experiments she performed with materials from the assistant gave “alarmingly inconsistent” results for no apparent reason, she said in an interview with an investigation committee.

She brought her concerns to a senior researcher, and the research assistant, Ryan Evanoff, was asked to “detail what he had done,” but apparently nothing came of it.

The supervisor indicated that the postdoc’s initial message outlining her concerns “was not clear enough,” but the postdoc thought she’d been clear and says she’d been “extremely careful” due to the severity of the situation.

‘Highly professional, but the process seems to take a long time’: Is this the best way to correct the record?

A Nature journal has retracted a 2021 paper which made a bold claim about certain chemical reactions after several researchers raised questions about the analysis – but not before another group pulled their own article which built on the flawed findings.

The first article, “The amine-catalysed Suzuki–Miyaura-type coupling of aryl halides and arylboronic acids,” appeared in Nature Catalysis in January. Most of the authors were affiliated with Hefei University of Technology, in China. The paper has been cited five times, according to Clarivate Analytics’ Web of Science.

After publication, at least three groups of researchers published Matters Arising letters in the journal questioning the validity of the results, all of which appeared on December 2:

Researchers ‘devastated’ after finding manipulated data in study of pediatric brain tumors

An international group of cancer researchers has lost an influential 2020 paper in Nature Neuroscience after finding problems with the data that triggered an institutional investigation.

The article, “Tumor necrosis factor overcomes immune evasion in p53-mutant medulloblastoma,” represented a potentially major advance in the treatment of pediatric brain tumors, according to Robert Wechsler-Reya, the director of the Tumor Initiation & Maintenance Program at the Sanford Burnham Prebys Medical Discovery Institute, in La Jolla, Calif., and the senior author of the paper, which has been cited 17 times, per Clarivate Analytics’ Web of Science:

Exercise researcher earns more retractions as investigations mount

Co-author James Steele, one of the sleuths who brought the issues to attention

Retractions are slowly stacking up for an exercise researcher in Brazil whose work has come under scrutiny by data sleuths, including a couple of his erstwhile co-authors. The concerns prompted an investigation by his former institution into one of his academic supervisors, who may be facing sanctions, Retraction Watch has learned.

In June 2020, the sleuths posted a preprint calling for the retraction of seven papers by the researcher, Matheus Barbalho, a PhD student at the Centro de Ciências Biológicas e da Saúde, part of the Universidade da Amazônia, in Belém. The reason, according to the sleuths – who included James Steele and James Fisher, of Solent University in the United Kingdom, both of whom were co-authors on papers with Barbalho: the data were, in their view “atypical, improbable, and to put it bluntly, pretty weird.”

Since then, journals have retracted two of Barbalho’s papers (he had lost one in April 2020), citing concerns about the data in the articles.

Paper on canine gastrointestinal illness dogged by lack of disclosures

A veterinary journal has retracted — in a big way — a 2021 paper about bowel disease in dogs by a group of authors who failed to disclose key conflicts of interest and then appear to have lied about the omission when pressed.

The article, “Utility of the combined use of 3 serologic markers in the diagnosis and monitoring of chronic enteropathies in dogs,” appeared in the Journal of Veterinary Internal Medicine, an official title of the American College of Veterinary Internal Medicine.

The first author was Juan Estruch, of Vetica Labs, a rather opaque company based in San Diego and of which Estruch is listed in securities documents as having been the CEO back in 2015.

AHA “regrets any confusion” and is reviewing meeting policies after outcry over Covid-19 vaccine abstract

Days after a leading heart journal issued an expression of concern for a meeting abstract suggesting that vaccines against Covid-19 may cause cardiac damage, its publisher, the American Heart Association (AHA), says it is reviewing how it screens such submissions.

As we reported late last month, “Mrna COVID Vaccines Dramatically Increase Endothelial Inflammatory Markers and ACS Risk as Measured by the PULS Cardiac Test: a Warning,” was presented at the AHA’s 2021 Scientific Sessions in mid-November and was published in Circulation.

The author was Steven Gundry, a cardiac surgeon by training who now sells dietary supplements on his website. Gundry also sees patients at the Center for Restorative Medicine and International Heart & Lung Institute in California and offers advice on YouTube. (His critics say what Gundry peddles costs much more than it’s worth.)

After an outcry, Circulation flagged the published poster with the following notice:

Authors retract, resubmit “very poorly conducted” meta-analysis of COVID-19 treatment

A journal has retracted a meta-analysis on Covid-19 after concerned readers complained about the quality — or lack thereof — of the study.

The article, “A meta-analysis of granulocyte-macrophage colony-stimulating factor (GM-CSF) antibody treatment for COVID-19 patients,” appeared in Therapeutic Advances in Chronic Disease, a SAGE title.
