Major heart journal retracts two papers from Oxford group for misconduct

The Journal of the American College of Cardiology (JACC) has retracted two 2018 papers out of the University of Oxford because of misconduct.

Both retraction notices blame first author Alexander Liu, a student in the lab at the time, who disputes the retractions. The studies were part of a larger effort to improve heart imaging that caught the attention of cardiologists and was highlighted by Oxford in 2015.

Here’s the notice for “Diagnosis of Microvascular Angina Using Cardiac Magnetic Resonance,” a paper that has been cited 59 times, according to Clarivate Analytics’ Web of Science, earning it a “highly cited paper” designation:

Given “wrong pathology slides,” heart journal retracts paper

A cardiology journal has retracted a paper after the authors were unable to provide correct pathology slides to replace the wrong ones submitted with the original manuscript.

The paper is titled “Aortic Valve Endocarditis and Coronary Angiography With Cerebral Embolic Protection,” published on April 10, 2017 in The Journal of the American College of Cardiology: Cardiovascular Interventions (JACC:CI). It has not yet been cited, according to Clarivate Analytics’ Web of Science.

JACC:CI retracted the paper on Aug. 14, providing this notice: Continue reading Given “wrong pathology slides,” heart journal retracts paper

Journal knew about problems in a high-profile study before it came out — and did nothing for over a month

In June, Gene Emery, a journalist for Reuters Health, was assigned to write a story about an upcoming paper in the Journal of the American College of Cardiology, set to come off embargo and be released to the public in a few days. Pretty quickly, he noticed something seemed off.

Emery saw that the data presented in the tables of the paper — about awareness of the problem of heart disease among women and their doctors — didn’t seem to match the authors’ conclusions. For instance, on a scale of 1 to 5 rating preparedness to assess female patients’ risk (with 5 being the most prepared), 64% of doctors answered 4 or 5; but the paper said “only a minority” of doctors felt well-prepared (findings echoed in an accompanying press release). On Monday June 19, four days before the paper was set to publish, Emery told the corresponding author — C. Noel Bairey Merz, Medical Director of the Women’s Heart Center at Cedars-Sinai in Los Angeles — about the discrepancy; she told him to rely on the data in the table.

But the more Emery and his editors looked, the more problems they found with the paper. They alerted the journal hours before it was set to publish, hoping that was enough to halt the process. It wasn’t.

Author objects to retraction of heart study, implies industry played role

JACC

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.

Here’s the retraction notice for “Impact of Rotor Ablation in Nonparoxysmal Atrial Fibrillation Patients Results From the Randomized OASIS Trial:” Continue reading Author objects to retraction of heart study, implies industry played role

Doctor suspended in UK after faking co-authors, data

Screen Shot 2016-02-24 at 11.04.56 AMA doctor in Manchester, UK has received a year’s suspension by the Medical Practitioners Tribunal Service.

Gemina Doolub admitted that she fabricated research data and submitted papers without the knowledge of her co-authors, including faking an email address for a co-author, a news story in the BMJ reports. The research in question was part of two retractions that Doolub received in 2013, one of which we covered at the time.

Doolub’s research examined ways to treat and avoid microvascular obstruction — that is, blocked arteries. Doolub did the work while at Oxford.

“Intracoronary Adenosine versus Intravenous Adenosine during Primary PCI for ST-Elevation Myocardial Infarction: Which One Offers Better Outcomes in terms of Microvascular Obstruction?” was published in International Scholarly Research Notices Cardiology and has not yet been cited, according to Thomson Reuters Web of Science.

As the BMJ reports, in that paper,

Yup, this happened: “Mystery” writer impersonated cardiovascular pathologist, penned published letter

A 2014 letter in the Journal of the American College of Cardiology has been retracted because editors aren’t sure who wrote it.

“Can Grayscale IVUS Detect Necrotic Core-Rich Plaque?”, a letter on the potential of intravascular ultrasound, was submitted under the name of a researcher at the University of Copenhagen, Erling Falk. The paper was sent with a Gmail account (a technique used by some academics to conduct fake peer reviews), and editors communicated with the author through the acceptance process.

Shortly after the letter was published, Erling Falk of Aarhus University contacted the journal and asked who wrote the letter. They discovered that nobody by that name worked at the University of Copenhagen and emails to the author’s Gmail address went unanswered. So the journal issued a retraction.

Here’s the complete notice:

Two detailed retraction notices correct the cardiology record

jaccTwo American College of Cardiology conference abstracts published earlier this year in the Journal of the American College of Cardiology (JACC) have been retracted, one because the authors were actually measuring something other than what they reported, and the other because newer software invalidated the results.

Here’s the notice for “Worsening of Pre-Existing Valvulopathy With A New Obesity Drug Lorcaserin, A Selective 5-Hydroxytryptamine 2C Receptor Agonist: A Meta-Analysis of Randomized Controlled Trials” by Hemang B. Panchal, Parthav Patel, Brijal Patel, Rakeshkumar Patel, and Henry Philip of East Tennessee State University: Continue reading Two detailed retraction notices correct the cardiology record

Pfizer database errors cause two voluminous retractions for JACC statin-biomarker papers

Jacc1212coverCoding errors in a database maintained by Pfizer have led authors to retract two heart biomarker papers in the Journal of the American College of Cardiology.

The two notices, for “Prediction of cardiovascular events in statin-treated patients by lipid and non-lipid biomarkers” and “Plasma PCSK9 levels and clinical outcomes in the TNT (Treating to New Targets) Trial,” are highly detailed and say the same thing: Continue reading Pfizer database errors cause two voluminous retractions for JACC statin-biomarker papers

Concern — in triplicate — arrives for Poldermans papers

Jacc1212coverThe Journal of the American College of Cardiology, or JACC, has issued expressions of concern for three papers by Don Poldermans, the Dutch cardiologist who was fired earlier this year amid allegations of misconduct.

Cardiobrief’s Larry Husten had the story first.

The, um, heart of the matter is that neither the investigators at Erasmus Medical Center, Poldermans’ former institution, nor the JACC editors, can say whether the researchers conduct rose to the level of fabricating data.
