A Survey of Iranian Retracted Publications Indexed in PubMed

Background: Retraction is a mechanism for correcting the literature and a warning for readers in relation to publications that contain serious flaws or erroneous data. As a result of growth and development of Iranian publications in the last two decades, that brings unethical behavior of researchers led to retraction of their publications. We aimed to investigate Iranian retracted publications indexed in PubMed database. Methods: All Iranian retracted publications published in PubMed up to Dec 2017 have been retrieved. Bibliographic information of retracted publications, retraction notice, time lag between article publication date and the date of retraction notice, reasons of retraction, Issuer of retraction and acknowledge information of retracted publication were recorded. Additionally, citation data of retracted publications before 2013 were analyzed. Results: Overall, 164 Iranian retracted publications were identified. Meantime lag was 20.8 months. "Islamic Azad University" and "Tehran University of Medical Sciences (TUMS)" were two affiliations that have received highest number of retracted publications. The most issuer of retraction publications was editor-in-chief and the most mentioned reasons for retractions were authorship issues, plagiarism, and redundant publication. Thirtythree (20.12%) publications have received funds from various agencies. Citation study of retracted publications indicates that these publications have received 789 citations (Citation per publication=11.6). Conclusion: Although Iranian retracted publications represent small portion of all Iranian publications, but the number of retracted publications has increased. More than half of retracted publications have had authorship issues and plagiarism that requires more attention to research ethics authorities.

Article title: “Hemopneumothorax associated with pneumorrachis following blunt chest trauma” Authors: Putu Eka Mardhika, Tjokorda Gde Bagus Mahadewa, Citra Aryanti Bibliometrics: Volume 2, Issue 2, pages 33-36 DOI: 10.36444/nsmc.v2i2.10 Neurologico Spinale Medico Chirurgico with Indoscholar is retracting the paper titled “Hemopneumothorax associated with pneumorrachis following blunt chest trauma” by Putu Eka Mardhika, Tjokorda Gde Bagus Mahadewa, Citra Aryanti, published in Volume 2, Issue 2, pages 33-36. Upon investigation, it was determined that a similar article, titled the same was submitted by the authors and simultaneously published in another journal (redundant publication) As a result, the article published in Neurologico Spinale Medico Chirurgico has been retracted and should not be cited in the electronic or print version of the journal.

(RETRACTED) Pengaruh Pemberian Model Latihan Isometrik Terhadap Kadar Glukosa Darah Pada Mencit (Mus Musculus) Diabetes Mellitus

AbstrakTHIS ARTICLE IS RETRACTED DUE TO REDUNDANT PUBLICATION. Berdasarkan penelitian terbaru, olahraga/ latihan mempunyai efek yang signifikan dalam menurunkan glukosa darah penelitian ini bertujuan untuk mengidentifikasi efek dari model latihan isometrik terhadap kadar glukosa darah pada mencit yang dikondisikan mengalami diabetes mellitus. Penelitian ini adalah penelitian eksperimen murni (True Experiment). Menggunakan rancangan eksperimen The Randomise Post Test Only Control Group Design. Sampel adalah mencit jantan dengan berat 20-27 gram. 27 ekor mencit jantan dibagi menjadi tiga kelompok yaitu kelompok control terdiri dari mencit normal yang diinjeksi NaCl sebagai placebo. Kelompok kedua adalah mencit diabetes yang tidak diberikan latihan isometrik dan kelompok ketiga adalah mencit diabetes diberikan latihan isometrik. Kelompok kedua dan ketiga diinjeksi streptozotocin (STZ) untuk meginduksi DM. Setelah 48 jam diinjeksi, kedua kelompok diberikan glukosa oral (Dextrose-40%). Kelompok ketiga diberikan latihan isometrik menggunakan treadmill selama 23.31 menit dengan kecepatan 21 cm/detik dan sudut elevasi 0°. Data dianalisa menggunakan One Kolmogorov-Smirnov test, ANOVA test dan Least Significance Difference (LSD) dengan α<0.05. Analisa One Kolmogorov-Smirnov test p=0.94 pada kelompok kontrol, p=0.50 pada kelompok mencit diabetes, and p=0.19 pada kelompok perlakuan. Hasil ANOVA tes adalah p=0.08. Hasil LSD untuk gluksa darah adalah p=0.23 untuk kelompok perlakuan. Hal ini mungkin terjadi karena pada kelompok kedua terdapat 2 mencit dengan glukosa darah normal dan pada kelompok ketiga kadar glukosa darah awal tidak diketahui. Sehingga, mungkin saja kelompok tersebut juga memiliki kadar glukosa darah normal. Dapat disimpulkan bahwa tidak ada efek latihan isometrik dalam menurunkan kadar glukosa darah. Penelitian selanjutnya disarankan mengidentifikasi lebih jauh tentang frekuensi dan intensitas latihan isometrik yang dapat mempengaruhi penurunan kadar glukosa darah.

This paper was published in BioImpacts in 2013 (doi: 10.5681/bi.2013.005).1 Based on an email received from a researcher recently, we were informed that this published paper presented some data (i.e., Fig. 3a and 3b) as same as data presented in three other published papers (i.e., doi: 10.1111/Cbdd.12318; doi: 10.1111/Cbdd.12318; and doi: 10.1186/1477-3155-10-46),2-4 which are considered as the ethical misconduct. This issue was brought up with and comprehensively investigated by the editorial team of BioImpacts through comparison of the papers and the within-data. As a result, in accordance with the Committee on Publication Ethics (COPE), the editors decided to retract this paper. The authors were informed and advised on this serious ethical breach. Based on the COPE guidelines on the retraction, BioImpacts considers retracting a publication if: - It has clear evidence that the findings are unreliable, either as a result of misconduct (e.g., data fabrication and/or falsification) or honest error (e.g. miscalculation or experimental error). - The findings have previously been published elsewhere without proper crossreferencing, permission or justification (i.e. cases of redundant publication). As a peer-review multidisciplinary international "Publish Free" and "Access Free" journal, BioImpacts strongly adheres to the "Publication Ethics", and its foremost goal is to preserve the integrity of the scientific reports in the highest standards, therefore, the journal takes all issues of publication misconduct seriously.
