A pharmacology journal has retracted a 2011 paper after concluding images in three figures had been manipulated.
According to the British Journal of Pharmacology, four of the five authors claim they played no role in the manipulation. There is no comment from the remaining author, first author Ian Morecroft, a research associate at the University of Glasgow.
Here’s more from the notice, which says an investigation at the University of Glasgow is ongoing:
In February, Lusine Abrahamyan, an assistant professor at the University of Toronto, was contacted by ResearchGate. Her name was listed on a 2016 paper in a heart journal, the site told her — was Abrahamyan indeed a co-author?
Um, no, she was not. In fact, before that moment, she didn’t know such a paper existed.
It turns out, Abrahamyan had supervised the thesis of the first author — who, she soon learned, had also published an identical paper in another heart journal. Both have since been retracted.
How did this happen?
Attention Joachim Boldt: The 1990s are calling, and they want their papers back.
The Annals of Thoracic Surgery has retracted two papers from the early 1990s on which Boldt was the first author – bringing the retraction tally for the disgraced German anesthesiologist to 96, by our count. Both articles were found to contain manipulated data.
The first paper, from 1990, was titled “Acute Preoperative Plasmapheresis and Established Blood Conservation Techniques,” and was written when Boldt was on the faculty at Justus-Liebig University, in Giessen.
According to the notice:
One of the retracted papers in the Journal of Neurosurgery (JNS) had multiple problems that were “too extensive to revise,” according to the lengthy retraction notice, relating to issues with authorship, data analyses, and patient enrollment. The notice is signed by first author Hua Liu of the Nanjing Medical University in China.
Liu is also the first author of another recently retracted paper in Frontiers in Neuroscience, pulled for incorrectly categorizing patients.
A publisher in the Netherlands has retracted 13 published studies and withdrawn 52 that were under consideration (but not yet published) after learning that someone illegally accessed its workflows to add fake authors and manipulate text.
According to Seyyed Mohammad Miri, the founder, CEO, and managing director of Kowsar Publishing, the 13 retracted papers all included extra authors added by the same Internet Protocol (IP) address. Cyber police in Iran found the same IP address had also accessed the 52 other papers, which were in various stages of the publishing process (such as peer review) and not yet online, Miri told Retraction Watch.
Most of the authors on the 13 retracted papers are based in institutions in Iran; some were co-authors on the 58 retractions recently issued as part of a mass clean-up by publishers BioMed Central and Springer, citing fake reviews, adding inappropriate authors, and plagiarism.
Around six or seven months ago, the affected journals — in collaboration with Kowsar, their publisher — filed a court case in Tehran, Iran against this IP address, Miri said. Read the rest of this entry »
Researchers have retracted and replaced a 2014 paper in JAMA Internal Medicine after realizing a number of errors had affected the findings.
The authors note the mistakes do not have a significant impact on the overall proportion of heart patients who participated in cardiac rehab. However, a number of findings were affected, such as the difference in participation in cardiac rehab defined by race, and how the overall participation has changed throughout the years.
Therefore, JAMA Internal Medicine has published a lengthy notice of retraction and replacement, which explains the errors made in the original paper, and updated the first paper with a new version of the study.
The retraction notices, which appear in Clinical Science, mention investigations into the work of Kou-Gi Shyu at the Shin-Kong Wu Ho-Su Memorial Hospital and Taipei Medical University (TMU).
Shyu is listed as being affiliated with both institutions in the original papers, but a TMU official told us Shyu left his teaching role at TMU amidst the probe. Shyr-Yi Lin, professor of medicine and dean of research and development at TMU, noted: Read the rest of this entry »
A second paper about a major randomized trial in Japanese patients with heart disease is being retracted, after an investigation reportedly found multiple problems with the paper.
As predicted by Pharma Japan, Hypertension Research is retracting a 2011 paper, already the subject of two errata. Although a spokesperson said she couldn’t say why the paper was being retracted, as the notice was still in production, editor Toshihiko Ishimitsu told us: Read the rest of this entry »
A German district attorney has fined a doctor who participated in a bogus study showing chocolate helps weight loss, designed to illustrate how shady science can make the news, arguing it was unethical to ask people to participate unknowingly in such a scam.
As soon as the study was published, critics raised questions over whether it was appropriate to include volunteers in a bogus clinical trial, which included giving blood. Recently, a German district attorney for professional conduct of physicians ruled that it was not.
In an anonymized version of a decision from the district attorney – who investigates on possible violations of the physicians’ professional law – he fined the doctor who participated in a bogus study about the health benefits of chocolate 500 Euros for not obtaining proper consent from the people who volunteered to participate, and for not involving an ethics committee.

The Journal of the American College of Cardiology (JACC) has retracted a recently published paper that questioned the effectiveness of a treatment for irregular heartbeat, against the last author’s wishes.
Andrea Natale, the study’s last and corresponding author and Executive Medical Director of Texas Cardiac Arrhythmia at Austin, took to social media today to express his frustration in the retraction of the July paper, which showed electrical rotors were less effective at fixing irregular heartbeat than other treatments. On Twitter, Natale implied industry played a role in its demise.
However, according to the retraction notice, the paper was felled by problems with randomization; Natale has admitted that some patients were removed from the analysis after one center included them incorrectly.
