Study of autism and vitamin D earns retraction after questions about reliability

Marco Vertch

A pediatrics journal has retracted a 2016 article purporting to be the first randomized controlled trial on the effects of vitamin D supplements on autism over concerns about the reliability of the findings.

The paper, “Randomized controlled trial of vitamin D supplementation in children with autism spectrum disorder,” appeared in the Journal of Child Psychology and Psychiatry and has been cited 27 times, according to Clarivate Analytics’ Web of Science, earning it a “highly cited paper” designation compared to its counterparts of a similar age.

The authors came from Egypt, Saudi Arabia, China, Chile, the UK and Norway. According to the abstract, the researchers looked at the effects of vitamin D supplements on 109 boys and girls with autism:

Majority of journal’s editorial board resigns after publisher’s handling of letter about move to open access

A leading journal in ecology and evolution is going through an evolution of its own, following the resignation of its editor in chief and more than half of its editorial board.

The mass exodus at Diversity & Distributions came after Wiley, which publishes the journal, allegedly blocked it from running a letter protesting the company’s decision to make D & D open access (the company disputes the claim, as we’ll detail in a bit). A letter about the issue, signed by scores of researchers worldwide, decried Wiley’s move: Continue reading Majority of journal’s editorial board resigns after publisher’s handling of letter about move to open access

Dental researcher in Spain up to 18 retractions

Jose Luis Calvo-Guirado

A researcher in Spain who studies dental implants has had another six papers retracted, for a total of 18.

José Luis Calvo-Guirado‘s latest retraction, which along with the other 17 appeared in Clinical Oral Implants Research, a Wiley title, was for “image discrepancies resulting in unreliable data.” Three appeared in June, and two in July, also for image issues. The researcher also has at least two corrections; one  in Annals of Anatomy — Anatomischer Anzeiger and one in Materials. Continue reading Dental researcher in Spain up to 18 retractions

When is asparagus not asparagus? Why, when it’s ginger, of course!

Allow us to explain that headline.

Food Science & Nutrition has retracted a 2018 article by a group of researchers in China and Pakistan for plagiarism. The article was titled “Experimentally investigated the asparagus (Asparagus officinalis L.) drying with flat-plate collector under the natural convection indirect solar dryer.”  

Per the retraction notice: Continue reading When is asparagus not asparagus? Why, when it’s ginger, of course!

“Sufficiently serious” issues in study prompt company to yank drug approval application in China

The maker of a leading over-the-counter antacid has withdrawn its application for approval of the drug in China because a clinical trial of the product in that country was marred by “major protocol deviations.”

Researchers for the company, Reckitt Benckiser, maker of Gaviscon, had published a report on the study in 2015 in the journal Alimentary Pharmacology & Therapeutics. But the journal has now retracted the article, “Randomised clinical trial: The clinical efficacy and safety of an alginate‐antacid (Gaviscon Double Action) versus placebo, for decreasing upper gastrointestinal symptoms in symptomatic gastroesophageal reflux disease (GERD) in China,” at the behest of the drug maker.

What should happen to a paper published by Theranos?

Last December, a group of scientists at a biotech firm published a paper on a “miniaturized, robotic clinical laboratory.” The technique, according to the authors, “would benefit patients and physicians alike.”

Nothing terribly unusual there. But what was — and what caught the eye of a Retraction Watch reader — was the name of the last author: Elizabeth Holmes.

Misconduct probe of once rising star prompts retraction of cat’s meow paper

A group of Australian researchers who studied the cat’s meow as a model for urinary incontinence and other motor-neural issues in people have lost a 2015 paper in the wake of a misconduct investigation.

The target of the inquiry was Hari Subramanian, a former senior research fellow at the Queensland Brain Institute, part of the University of Queensland (UQ). Subramanian was leading studies of incontinence in the elderly, for which he sometimes used nerve stimulators on live rodents and cats. As The Australian reported last September, animal rights activists have objected to his research methods — which sometimes involved sticking probes into the brains of living animals.  

Recently, the school launched an investigation — prompted by an unknown complainant — into the integrity of Subramanian’s data in two articles, including one, now retracted, that appeared in the Journal of Comparative Neurology.  

The case is controversial, to say the least, replete with allegations of unfair attacks. Subramanian’s lawyer told us the journal may be reviewing its decision to retract the paper. (We couldn’t confirm that with the editor.)

Here’s what we’ve found out so far.

Dental journal pulls a dozen papers for recycled images and “unreliable data”

A leading orthodontics journal has retracted 12 papers after determining that they contained either reused images, questionable data or both. Several of the articles involved experiments conducted in dogs — and one person familiar with the case told us that the duplication was an attempt to avoid sacrificing more animals than necessary for the research.  

Although the list of authors on the articles varies, the common denominator is Jose Luis Calvo-Guirado, of the UCAM Universidad Católica San Antonio de Murcia, in Spain. Calvo-Guirado’s title at the institution is director de la Cátedra Internacional de Investigación en Odontología, which Google translates as director of the International Research Chair in Dentistry.  Calvo-Guirado also holds (or has held) a research professorship at SUNY Stony Brook in the Department of Prosthodontics and Digital Medicine, according to his CV.

Calvo-Guirado’s name is on at least 187 entries in PubMed. Of those, 40 appeared in Clinical Oral Implants Research, a Wiley title on whose editorial board the researcher served, according to his CV.

Sturgeon researcher nets 13 retractions for fake peer review

A fish scientist in Iran has now lost 13 papers about the properties of Sturgeon sperm — try saying that five times fast — and other ichthyological topics over concerns about faked peer review.

The three most recent retractions come from the Journal of Animal Physiology and Animal Nutrition. According to the notice:

Author: “The retractions were about bureaucracy, not science”

A researcher has retracted two 2014 papers, after discovering they had not gone through the proper approval process before being submitted.

The papers were part of a collaboration funded by the U.S. National Institutes of Health, which focused on solving protein structures. Adam Godzik, the senior author, told Retraction Watch that all papers had to be approved by a special committee before being submitted to a journal. Given the scale of the collaboration, the committee for the Joint Center for Structural Genomics (JCSG) would assess whether researchers who had made a previous contribution to the work should be added as authors.

Proteins: Structure, Function, and Bioinformatics retracted both papers after Godzik informed the editor in August 2014 that neither article had undergone the required review before being submitted to the journal. Although Wiley agreed to the retractions in an email to Godzik in September 2014,  the papers were only pulled in January—more than three years later.
