CDC: Falsified data did not affect C. diff results

downloadDespite the fact that a former employee of the Oregon Health Authority falsified 56 case reports that were included in a report by the U.S. Centers for Disease Control and Prevention (CDC), a re-analysis has found that the results of the report remain valid.

The report included information about 10,342 cases of potentially deadly infections due to Clostridium difficile, so removing the cases affected by the misconduct — 57 in total — “did not” alter the results, according to an analysis published today by the CDC:

Paper on chemtrails, a favorite subject of conspiracy theorists, retracted

ijerph-logo

A paper claiming to expose the “tightly held secret” that long clouds trailing from jets are toxic coal fly ash — and not, as the U.S. government says, primarily composed of harmless ice crystals — has been retracted.

The paper is called “Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health,” and was published in the International Journal of Environmental Research and Public Health in August. Author J. Marvin Herndon — a geophysicist, and self-described “independent researcher” — also distributed a press release about the findings.

The abstract explains:

The author presents evidence that toxic coal combustion fly ash is the most likely aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification and climate-modification purposes and describes some of the multifold consequences on public health.

The detailed retraction note, authored by the academic editor of the paper, Paul B. Tchounwou, a biologist at Jackson State University, points out some errors with the science, and notes that the “language of the paper is often not sufficiently scientifically objective:” Continue reading Paper on chemtrails, a favorite subject of conspiracy theorists, retracted

A mess: PLOS mistakenly publishes rejected ADHD-herbicide paper, retracts it

logoPLOS One has retracted a paper that links the most commonly used herbicide to ADHD, after it was “published in error.”

According to the note, the paper was “editorially rejected following peer review and consultation with the Editorial Board,” but ended up going through the production process anyway.

When we contacted the authors, they filled us in with more details.

Journal that published bogus chocolate study delisted from open access directory

logo_croppedThe journal that recently published a bogus study showing the health benefits of chocolate has been kicked out of a membership organization for open access journals.

According to the Directory of Open Access Journals (DOAJ), the International Archives of Medicine was removed from the list of member journals August 20, due to “suspected editorial misconduct by publisher.”

The journal is still was listed in PubMed until November 2014.

According to the DOAJ website, membership to the organization serves as a stamp of approval for OA journals:

Analysis of pilots with prostate cancer retracted for “inappropriate data”

Aerospace Medicine and Human PerformanceIn case any pilots out there are worrying about their risk of prostate cancer based on a recent meta-analysis that found they are at least twice as likely to develop the disease, they should relax — the paper has been retracted.

The reason: “including inappropriate data from two studies that should be ineligible.”

“The risk of prostate cancer in pilots: a meta-analysis” reviewed eight studies to determine whether airline pilots, who are regularly exposed to radiation and other occupational hazards, have a higher incidence of prostate cancer. However, it also included studies that reported on prostate cancer among all U.S. Armed Forces servicemen, not pilots.

The retraction notice was posted in May — only months after it was published in Aerospace Medicine and Human Performance in February. The notice included a letter to the editor outlining flaws in the meta-analysis and an apologetic response from first author, David Raslau at the Mayo Clinic.

Here’s the notice (appearing at the bottom of page 2):

Plague or anthrax on the subway? Think again, says now-corrected study

Cell SystemsAuthors of a widely covered study that documented traces of plague and anthrax on surfaces across New York City have revised the paper after public health officials challenged their interpretations of the data.

It’s hard to overestimate the attention these findings received when first published.

“Bubonic plague found in NYC subway,” wrote The Daily Beast.

“Your subway seat mate: Bubonic plague, anthrax, & mysterious DNA,” said Yahoo!

“NY subway has bubonic plague,” declared Newser.

Not so fast. In an erratum published July 29, the authors write: Continue reading Plague or anthrax on the subway? Think again, says now-corrected study

Paper cited by New York Times for key stat gets retracted

the-new-york-times-logoA paper that had served as the key aspect of an April New York Times article about a recent surge of violence against immigrants in South Africa has since been retracted for plagiarism.

The research, which appeared in the Mediterranean Journal of Social Sciences, had served as the source of the newspaper’s statement that the country is “home to about five million immigrants.” That figure was later quoted in other media outlets about the issue.

However, a 2011 census put the number closer to 2.2 million immigrants, according to the non-profit fact-checking organization Africa Check. After issuing a report about the discrepancy, which also quotes experts who say the numbers are unlikely to have doubled by 2015, Africa Check contacted the Times. As Africa Check reports:

JAMA issues mega-correction for data breach letter due to “wording and data errors”

s_cover_jcv062315A JAMA letter published in April on data breaches accidentally included some data that shouldn’t have been published, either — specifically, “wording and data errors” that affected five sentences and more than 10 entries in a table. One result — a reported increase in breaches over time — also went from statistically significant to “borderline” significant, according to the first author. (So yeah, this post earns our “mega correction” category.)

According to an author, an “older version” of a table made it into the letter, “Data Breaches of Protected Health Information in the United States,” which was corrected in the journal’s June 23/30 issue.

The letter and table in question detail 949 breaches of “unencrypted protected health information.”  The letter says the number of breaches has increased from 2010 to 2013; the original article claimed that the P value on that increase was <.001, but the correction says it’s really 0.07. The original says 29.1 million personal records were affected in those breaches; the real number is 29.0. And so on.

Lancet Oncology updates conflicts of interest statement for cancer-cell phone paper

lanoncThe Lancet Oncology is correcting a 2011 article about the cancer risks of radiofrequency electromagnetic fields, such as those from cell phones, to clarify information about potential conflicts of interest for one of the experts who was involved in its preparation.

The assessments appeared as a monograph for the International Agency for Research on Cancer (IARC).

However, after the 2011 paper “Carcinogenicity of radiofrequency electromagnetic fields” appeared, a reader raised allegations of conflicts of interest among its participants, which sparked a reconsideration of their disclosures.

The correction concerns the conflicts of interest for Niels Kuster of the Swiss Federal Institute of Technology in Zurich, also a board member of the non-profit IT’IS foundation.

Kuster told Retraction Watch he disclosed everything upfront:

Article on suicide in Egypt retracted for double publication

JForensicSci_ak9A 2012 article published in the Journal of Forensic Sciences is being retracted because of an “overlap with a previous publication by the same authors.”

The corresponding author, Heba Yassa, a lecturer at Assiut University in Egypt, readily explained in an email exchange that the mix-up was due to a miscommunication with the editor of another journal, which she believed was not going to publish the article. “I know accidentally that the editor…published the article.”

The article, which examined suicides in one of the largest provinces in Egypt between 2005 and 2009, found rates had gone up since 1987, and men tended to use more violent methods than women.

Here’s the retraction notice: Continue reading Article on suicide in Egypt retracted for double publication
