TL;DR: The originator of the idea, Eugene Garfield, formulated several critical points in bibliometrics that have shaped citation indexes, for example, libraries with limited funding should be selective about the journals they acquire and a bibliography should selectively cover 'high quality' sources.
Abstract: The past five decades have witnessed the so-called data deluge and publication explosion across all branches of science (1). Numerous academic journals have been launched that use a systematic approach to the submission, peer review, and publishing of information. To facilitate the wide use of published sources, libraries across the world have expanded cataloguing and advanced literature search techniques.
The first major step towards indexing academic journals and helping libraries acquire the most influential sources was made by the Institute for Scientific Information (ISI) in Philadelphia, USA, in 1960. The idea behind indexing and distributing information on published articles was to facilitate scientific communication between authors and readers (2). In other words, indexing was proposed as a tool for finding relevant sources of interest to the consumers. The originator of the idea, Eugene Garfield, also the founder of the ISI, formulated several critical points in bibliometrics that have shaped citation indexes, for example, libraries with limited funding should be selective about the journals they acquire; most read and highly cited journals constitute 'quality' sources; highly cited articles influence science; citations from highly-cited journals are weighed more than those from low-cited ones; and a bibliography should selectively cover 'high quality' sources.

TL;DR: In this paper , a systematic literature search called preferred reporting items for systematic reviews and meta-analyses (PRISMA) was used to review bacterial inhibition zone of the different herbal plant bioactive loaded polymer electrospun nanofibrous mats used for wound dressing applications.
Abstract: Treating wound is challenging if there is microbial colonization. In this paper, we tried to review comparison of bacterial inhibition zone of different herbal plant bioactive loaded polymer electrospun nanofibrous wound dressings. A systematic literature search called preferred reporting items for systematic reviews and meta-analyses (PRISMA) was used to review bacterial inhibition zone of the different herbal plant bioactive loaded polymer electrospun nanofibrous mats used for wound dressing applications. The literatures were searched from PubMed, Scopus, Web of Science, and Google Scholar databases published in English from 2010 to 2021. Two hundred articles were searched out; from these, 93 articles are selected and studied their bacterial inhibition zone, among them eight have the highest bacterial inhibition zone greater than or equal to 20 mm. From the studied plant bioactive extract loaded polymer electrospun nanofibrous mat wound dressings, PVA/Tridax procumbensviz have the highest antibacterial property (42 mm and 35 mm bacterial inhibition zone to Staphylococcus aureus and Escherichia coli, respectively). The second highest antibacterial property is PVA/honey/Curcuma longa with bacterial inhibition zone of 38 mm to S. aureus and the third one is PCL/carboxyethyl chitosan/PVA/Matricaria chamomile L. with an inhibition zone of 37.5 mm to E. coli bacteria.

TL;DR: The topic of the study is interesting and the authors tried to shed light on the probable beneficial effect of KD in cancer through retrieving animal studies, but some aspects of this study should be correct.
Abstract: Dear Editor, We have recently read with great interest the article, “Tumor cells growth and survival time with the ketogenic diet (KD) in animal models: A systematic review” that was written by Khodadadi et al . [1] The topic of the study is interesting and the authors tried to shed light on the probable beneficial effect of KD in cancer through retrieving animal studies. We would like to correct some aspects of this study.

TL;DR: Although Google Scholar was the search engine with the highest capacity to retrieve selected articles, it was the least effective, compared with scientific search engines, at providing information on the retraction of articles.
Abstract: Nowadays, a multitude of scientific publications on health science are being developed that require correct bibliographic search in order to avoid the use and inclusion of retracted literature in them. The use of these articles could directly affect the consistency of the scientific studies and could affect clinical practice. The aim of the present study was to evaluate the capacity of the main scientific literature search engines, both general (Gooogle Scholar) and scientific (PubMed, EMBASE, SCOPUS, and Web of Science), used in health sciences in order to check their ability to detect and warn users of retracted articles in the searches carried out. The sample of retracted articles was obtained from RetractionWatch. The results showed that although Google Scholar was the search engine with the highest capacity to retrieve selected articles, it was the least effective, compared with scientific search engines, at providing information on the retraction of articles. The use of different scientific search engines to retrieve as many scientific articles as possible, as well as never using only a generic search engine, is highly recommended. This will reduce the possibility of including retracted articles and will avoid affecting the reliability of the scientific studies carried out.

TL;DR: The content coverage and practical utility of PubMed, Scopus, Web of Science, and Google Scholar are compared and PubMed remains an optimal tool in biomedical electronic research.
Abstract: The evolution of the electronic age has led to the development of numerous medical databases on the World Wide Web, offering search facilities on a particular subject and the ability to perform citation analysis. We compared the content coverage and practical utility of PubMed, Scopus, Web of Science, and Google Scholar. The official Web pages of the databases were used to extract information on the range of journals covered, search facilities and restrictions, and update frequency. We used the example of a keyword search to evaluate the usefulness of these databases in biomedical information retrieval and a specific published article to evaluate their utility in performing citation analysis. All databases were practical in use and offered numerous search facilities. PubMed and Google Scholar are accessed for free. The keyword search with PubMed offers optimal update frequency and includes online early articles; other databases can rate articles by number of citations, as an index of importance. For citation analysis, Scopus offers about 20% more coverage than Web of Science, whereas Google Scholar offers results of inconsistent accuracy. PubMed remains an optimal tool in biomedical electronic research. Scopus covers a wider journal range, of help both in keyword searching and citation analysis, but it is currently limited to recent articles (published after 1995) compared with Web of Science. Google Scholar, as for the Web in general, can help in the retrieval of even the most obscure information but its use is marred by inadequate, less often updated, citation information.

TL;DR: ‘The uncritical citation of disputed data by a writer, whether it be deliberate or not, is a serious matter.
Abstract: Objectives To investigate whether longitudinal structural network efficiency is associated with cognitive decline and whether baseline network efficiency predicts mortality in cerebral small vessel disease (SVD). Methods A prospective, single-centre cohort consisting of 277 non-demented individuals with SVD was conducted. In 2011 and 2015, all participants were scanned with MRI and underwent neuropsychological assessment. We computed network properties using graph theory from probabilistic tractography and calculated changes in psychomotor speed and overall cognitive index. Multiple linear regressions were performed, while adjusting for potential confounders. We divided the group into mild-to-moderate white matter hyperintensities (WMH) and severe WMH group based on median split on WMH volume. Results The decline in global efficiency was significantly associated with a decline in psychomotor speed in the group with severe WMH (β=0.18, p=0.03) and a trend with change in cognitive index (β=0.14, p=0.068), which diminished after adjusting for imaging markers for SVD. Baseline global efficiency was associated with all-cause mortality (HR per decrease of 1 SD 0.43, 95% CI 0.23 to 0.80, p=0.008, C-statistic 0.76). Conclusion Disruption of the network efficiency, a metric assessing the efficiency of network information transfer, plays an important role in explaining cognitive decline in SVD, which was however not independent of imaging markers of SVD. Furthermore, baseline network efficiency predicts risk of mortality in SVD that may reflect the global health status of the brain in SVD. This emphasises the importance of structural network analysis in the context of SVD research and the use of network measures as surrogate markers in research setting.

TL;DR: The uncritical citation of disputed data by a writer, whether it be deliberate or not, is a serious matter as discussed by the authors, and many naive students may be swayed by unfounded assertions presented by a writers who is unaware of the criticisms.
Abstract: “The uncritical citation of disputed data by a writer, whether it be deliberate or not, is a serious matter. Of course, knowingly propagandizing unsubstantiated claims is particularly abhorrent, but just as many naive students may be swayed by unfounded assertions presented by a writer who is unaware of the criticisms. Buried in scholarly journals, critical notes are increasingly likely to be overlooked with the passage of time, while the studies to which they pertain, having been reported more widely, are apt to be rediscovered.” (I)
