Anversa cardiac stem cell lab earns 13 retractions
Two months after Harvard and the Brigham and Women’s Hospital said they were requesting the retraction of more than 30 papers from a former cardiac stem cell lab there, two American Heart Association journals have retracted more than a dozen papers from the lab. Yesterday, Circulation retracted three papers, and Circulation Research retracted 10. All 13 were … Continue reading Anversa cardiac stem cell lab earns 13 retractions
Caught Our Notice: Using this research tool? You’d better ask first
Title: Patient Education After CABG: Are We Teaching the Wrong Information? What Caught Our Attention: We’ve written about the controversy surrounding a commonly used tool to measure whether patients are sticking to their drug regimen, known as the Morisky Medication Adherence Scale (MMAS-8). It can cost thousands of dollars — and using it without payment/permission […]

A shadow was cast on a bone researcher’s work. What are journals doing about his papers?
Last year, a researcher cast doubt on a bone scientist’s clinical trials, suggesting some of the findings may not be legitimate. So what’s happened since? Since 2015, journals have retracted 14 papers by bone researcher Yoshihiro Sato, based at Mitate Hospital in Japan, for issues ranging from self-plagiarism, to problems with data, to including co-authors without their consent. […]

Author lifts from one paper in two different articles. Why does one journal retract, while the other corrects?
Are there instances when similarities between papers should be fixed by a correction, rather than a retraction? We’re asking ourselves that question after seeing two journals take very different approaches to a somewhat similar situation. Last year, Frontiers in Physiology retracted a paper by Anastasios Lymperopoulos at Nova Southeastern University in Florida because of an “an […]

Vector wasn’t a gift after all, correction notes
A paper accidentally credited the wrong researcher with providing part of an experiment. It turns out that one of the authors supplied an expression vector to a Circulation paper about the molecular underpinnings of atherosclerosis — not the outside researcher originally thanked in the acknowledgements section. The correction notice to the paper makes the situation sound more mysterious […]

Raw files help fix 2003 figure by heart researcher accused of fraud
A researcher accused of misconduct by an anonymous Japanese blogger has corrected a 2003 paper in Circulation Research, after providing a university investigation with the original source files. Allegations of fraud have dogged Shokei Kim-Mitsuyama for years, and even caused him to step down from his position as editor in chief at another journal. However, Kim-Mitsuyama and his […]

Biologist’s research under investigation in Sweden after being questioned on PubPeer
The University of Gothenburg in Sweden is investigating several papers co-authored by biologist Suchitra Sumitran-Holgersson after they were challenged on PubPeer. Sumitran-Holgersson already has one retraction under her belt — of a 2005 Blood paper, after another investigation concluded the results “cannot be considered reliable.” Sumitran-Holgersson and her husband, co-author Jan Holgersson, did not sign the retraction notice. Both were […]

8th retraction appears for researcher who faked patient records
An 8th paper has been retracted for Anna Ahimastos, a heart researcher who faked patient records. It’s the last in a chain of retractions that were the result of an investigation by her former workplace, Baker IDI Heart & Diabetes Institute in Australia. As with the others, she did not agree to the retraction. The investigation found fabricated patients records in […]

Investigation prompts 5th retraction for cancer researcher for “unresolvable concerns”
An investigation at the University of New South Wales in Australia has led to a fifth retraction for a cancer researcher long accused of misconduct, due to “unresolvable concerns” with some images. As we reported in December, UNSW cleared Levon Khachigian of misconduct, concluding that his previous issues stemmed from “genuine error or honest oversight.” Now, Circulation Research is retracting one […]
