Study claiming hate cuts 12 years off gay lives retracted

Low Library, Columbia University

After years of back and forth, a highly cited paper that appeared to show that gay people who live in areas where people were highly prejudiced against them had a significantly shorter life expectancy has been retracted.

The paper, “Structural stigma and all-cause mortality in sexual minority populations,”  was published in 2014 by Mark Hatzenbuehler of Columbia University and colleagues. As we reported last year, Mark Regnerus, of the University of Texas at Austin, published a paper describing his failed attempts to replicate the study in 2016: Continue reading Study claiming hate cuts 12 years off gay lives retracted

Journals stamp expressions of concern on 15 papers from Anversa’s cardiac stem cell lab

Piero Anversa

More than four and a half years after questions were first raised about work in a cardiac stem cell lab at Harvard and the Brigham and Women’s Hospital, a year and a half after the Brigham and Partners Healthcare paid $10 million to settle allegations of fraud in the lab’s data, a month after Harvard the Brigham disclosed that they were calling for the retractions of more than 30 papers from the lab, and three weeks after the NIH paused a clinical trial based on the work, two leading journals have issued an expression of concern about 15 papers from the lab.

But expressions of concern are not retractions, of course. From the notice, in Circulation and Circulation Research, both of which are published by the American Heart Association: Continue reading Journals stamp expressions of concern on 15 papers from Anversa’s cardiac stem cell lab

“The final verdict:” Lancet retracts two papers by Macchiarini

Paolo Macchiarini

The Lancet chapter of the Paolo Macchiarini saga appears to finally be over.

In an editorial titled “The final verdict on Paolo Macchiarini: guilty of misconduct,” the editors of the journal announce that they are retracting two papers by the now-disgraced surgeon and colleagues “after receiving requests to do so from the new President of the Karolinska Institute (KI), Ole Petter Ottersen.” Late last month, Ottersen declared Macchiarini and six other researchers — including one of the whistleblowers in the case — guilty of misconduct.

The long story took many twists and turns — for instance, in September 2015, Lancet editors wrote an editorial with close to the opposite title: “Paolo Macchiarini is not guilty of scientific misconduct,” published after KI released the results of a previous investigation:   Continue reading “The final verdict:” Lancet retracts two papers by Macchiarini

Caught Our Notice: A team from Harvard, Cornell, Cambridge, HHMI, and UCSF can’t reproduce a paper’s findings

What Caught Our Attention: Any time there’s an issue with a paper co-authored by researchers from such high-profile institutions as Harvard, Cornell, and the University of Cambridge, we take notice. In this case, the group — which included Laurie Glimcher, then-dean at Cornell, now president of the Dana-Farber Cancer Institute — chose to retract a 2013 paper from a Cell journal after learning they couldn’t reproduce some of the experiments.

Caught Our Notice: Retraction eight as errors in Wansink paper are “too voluminous” for a correction

Title: Shifts in the Enjoyment of Healthy and Unhealthy Behaviors Affect Short- and Long-Term Postbariatric Weight Loss

What Caught Our Attention: Cornell food marketing researcher Brian Wansink, the one-time media darling who has been dogged by mounting criticism of his findings, has lost another paper to retraction. As we’ve noted in the past, corrections for Wansink’s work tend to be long. This time, “the number of errors is too voluminous to be executed by issuing a correction statement,” according to the retraction notice for a paper about behaviors following weight loss surgery. Continue reading Caught Our Notice: Retraction eight as errors in Wansink paper are “too voluminous” for a correction

Macchiarini, 3 co-authors found guilty of misconduct in 2015 paper

The Karolinska Institutet in Sweden has declared that once-lauded surgeon Paolo Macchiarini and three co-authors committed misconduct in a 2015 paper.

The decision by KI’s vice chancellor will be followed by a request to retract the paper, published by the journal Respiration.

In the paper, the researchers described the case of a man with an acute lung disorder, in which he received an experimental treatment involving the use of his own blood-derived cells and the drug erythropoietin, which stimulates the production of red blood cells. The patient “demonstrated an immediate, albeit temporary, clinical improvement,” according to the authors. However, he ultimately died of multisystem organ failure.

Title: Endotoxaemia during left ventricular assist device insertion: relationship between risk factors and outcome

What Caught Our Attention: Robert J. Frumento first caught our notice in 2013, as a coauthor on a paper retracted with a nonspecific reference to author misconduct.  Three years later, Frumento was clearly identified as having fabricated data and a master’s degree, and added three retractions to his name. Now he’s got a fifth retraction, this one citing missing data and a lack of proof that data blinding was performed correctly.   Continue reading Caught Our Notice: Columbia researcher up to five retractions

Swedish review board finds misconduct by Macchiarini, calls for six retractions

Paolo Macchiarini

An ethical review board in Sweden is asking journals to retract six papers co-authored by former star surgeon Paolo Macchiarini, after concluding that he and his co-authors committed misconduct.

One of the papers is the seminal 2011 article in The Lancet, which described the first case of a transplant using an artificial trachea seeded with the patient’s own stem cells, and now bears an expression of concern from The Lancet editors. Over time, multiple authors have asked to be removed from the paper.

The Expert Group on Scientific Misconduct at the Central Ethical Review Board has determined that concerns over that paper — and five others co-authored by Macchiarini, once based at the Karolinska Institutet (KI) — were justified. In a press release, it says:

Title: Promoting child-initiated social-communication in children with autism: Son-Rise Program intervention effects

What caught our attention: When journalist Brendan Borrell was investigating a controversial autism treatment program for Spectrum, he came across a study where lead author Kat Houghton failed to disclose a prior relationship with the treatment center that taught the program, called Son-Rise.

The Spectrum article notes:

“No wrongdoing had occurred,” says Karolinska, following investigation of cancer research

A journal has removed an expression of concern for a 2011 paper after Karolinska Institutet (KI) “concluded no wrongdoing had occurred.” 

In June, Journal of Cell Science (JCS) issued the expression of concern, after a reader contacted the editors with questions about the data in one of the figures. JCS investigated but could not resolve the issue, and in March 2017 turned the case over to KI where the authors are based.

The 2011 paper had already received a correction in 2016, citing inadvertent figure duplication.

In late August, KI concluded its investigation into the 2011 paper by last author Boris Zhivotovsky; JCS has now updated the expression of concern with a publisher’s note: Continue reading “No wrongdoing had occurred,” says Karolinska, following investigation of cancer research
