Food article pulled when authors can’t serve up data

homeHeaderLogoImage_en_USAn article about a dietary plan to help people lose weight has been retracted after other researchers raised concerns, and the authors failed to provide the data that supported their findings.

The retraction is accompanied by a Letter to the Editor by a group of outside researchers — including David Allison at the University of Alabama at Birmingham — who noticed “several substantial issues with data and calculations.” For instance, before the experiment even started, the two groups had very different weights: The control group averaged 96.5 kg, and the test group 91 kg. According to the letter, that difference is striking: Continue reading Food article pulled when authors can’t serve up data

St. Jude investigation finds faked data in brain tumor paper

S00396060An investigation at St. Jude Children’s Hospital into “irregularities” in a figure featured in a neuroblastoma paper has concluded that the image was fabricated. The paper, published in Surgery in 2012, was retracted on Friday.

Here’s the full retraction notice for “Liposome-encapsulated curcumin suppresses neuroblastoma growth through nuclear factor-kappa B inhibition:”

Heart researcher who faked patient data gets third retraction

Screen Shot 2015-11-06 at 6.38.09 PMA heart researcher has notched her third retraction, a small 2006 trial in Annals of Internal Medicine which seemed to show that a blood pressure drug could help people with artery disease walk further with less pain.

Earlier this year, Anna Ahimastos, formerly a researcher at Baker IDI Heart and Diabetes Institute in Melbourne, lost a larger clinical trial in JAMA and a subanalysis in Circulation Research after it was discovered she’d fabricated patient records. As principle investigator Bronwyn Kingwell told us in September:

Specifically, records were fabricated for trial participants that did not exist.

Now, following an investigation by the institute, her co-authors are proactively retracting papers, with more to come. The Annals of Internal Medicine paper, “Ramipril Markedly Improves Walking Ability in Patients With Peripheral Arterial Disease,” is being pulled due to an “inability to adequately validate primary data sources.” According to the note, Ahimastos “maintains the integrity of the data and validity of reported results:”

Study claiming dramatically higher rates of male military sexual trauma is retracted

psychological servicesA study that found a 15-fold increase in the rate of sexual trauma among men in the U.S. military — and sparked suggestions of “an epidemic of male-on-male sex crimes” in the military among conservative media outlets — has been retracted because of a flaw in the analysis.

The study, published just last week, appeared in Psychological Services, an American Psychological Association (APA) journal. In an announcement Sunday titled “American Psychological Association Retracts Article Positing Excessively High Rates of Sexual Trauma Among Military Men,” the APA said that “Scholars raised valid concerns regarding the design and statistical analysis which compromise the findings.” Here’s the text: Continue reading Study claiming dramatically higher rates of male military sexual trauma is retracted

Child psych studies halted for “unanticipated event,” sparking misconduct investigation

Mani Pavuluri

We’ve just learned what sparked a University of Illinois at Chicago investigation that recently concluded a child psychiatrist had committed misconduct: An “unanticipated event during a study,” which halted three studies and resulted in a letter sent out to 350 research subjects.

Earlier this week, we reported that an investigation at the University of Illinois at Chicago found “a preponderance of evidence” that child psychiatrist Mani Pavuluri had committed misconduct. The university told the U.S. Department of Health and Human Services about the investigation in 2013. The findings of the investigation led the university to request the retractions of three papers, one of which has been pulled so far, for not properly disclosing how much medication children had received outside the study.

Today, we found out what prompted the university to launch that investigation, courtesy of a statement from a spokesperson: Continue reading Child psych studies halted for “unanticipated event,” sparking misconduct investigation

Authors withdraw two papers from JBC — and that’s all we know

44.cover

Two sets of authors have withdrawn their papers from the Journal of Biological Chemistry. We’re telling you about the both together because, true to JBC form, there’s not too much to say.

The retraction notices for both papers — about the molecular underpinnings of cardiac fibroblasts and melanoma cells — are identical:

Author’s coordination of peer review flags 13 math papers

home_cover (3)Thirteen papers in Mathematics and Mechanics of Solids now have an expression of concern, after it came to light that an author on most of the papers coordinated the peer-review process.

David Y. Gao, a well-known and prolific mathematician at the Federation University Australia, is the author of 11 of the papers, and also the guest editor of the special issue in which they were set to appear. The papers were published online earlier this year.

A spokesperson for SAGE, which publishes the journal, confirmed that the publisher decided to re-review the papers after learning about Gao’s role in the peer-review process:

Got the blues? You can still see blue: Popular paper on sadness, color perception retracted

home_coverA paper published in August that caught the media’s eye for concluding that feeling sad influences how you see colors has been retracted, after the authors identified problems that undermined their findings.

The authors explain the problems in a detailed retraction note released today by Psychological Science. They note that they found sadness influenced how people see blues and yellows but not reds and greens, but they needed to compare those findings to each other in order to prove the validity of the conclusion. And once they performed that additional test, the conclusion no longer held up.

In the retraction note for “Sadness impairs color perception,” the editor reinforces that there was no foul play:

Mega-correction to several images in gastric cancer study

20.cover

A journal has issued a rather large correction — what we call “mega-correction” — to a 2014 paper on a gastric cancer biomarker that fixes problems with several of the study’s figures.

The authors write that despite the corrections, “the results and conclusions put forth in the article remain unchanged.”

The paper, “TMEFF2 Deregulation Contributes to Gastric Carcinogenesis and Indicates Poor Survival Outcome” explored the role of TMEFF2 in gastric cancer. The researchers found that the protein acts as a tumor suppressor, and low levels can indicate the presence of cancerous cells.

Here’s the full correction notice, published by Clinical Cancer Research in August:

Authors object to duplication verdict by environmental journal

10661An environmental journal has pulled a 2011 paper following an investigation, which revealed it contained “extensive similarities” with another paper published two years earlier by some of the same authors.

Two of the authors of the newly retracted paper — Zulfiqar Ahmad from Quaid-i-Azam University and Arshad Ashraf of the National Agricultural Research Center, both in Islamabad, Pakistan — were the sole authors of a 2008 paper about modeling groundwater flow in Indus Basin, Pakistan. The 2011 paper  — posted online in 2010 — focused on the same topic, but included two additional authors, one of whom told us he was unaware of the previous paper and agrees with the journal’s decision. Ahmad, however, has defended the 2011 paper and asked that the journal remove the retraction note.

Here’s the note, published in April by Environmental Monitoring and Assessment: Continue reading Authors object to duplication verdict by environmental journal
