Commentary: A Radiologist's Guide to Peer-Reviewing Manuscripts.

The Institute for Scientific Information (ISI) defines substantive articles as source items, which include only research and review (R&R) articles. This policy encourages some Journals to publish a significant number of original reports in the category of letters to the editor and reviews in the category of Editorials. Consequently, the Impact Factor (IF) fails to provide a fair comparison between medical journals. We introduce a new value, the Comprehensive Citation Factor (CCF), which would include in the denominator all original reports and review articles. We reassessed the 2007 ISI IF rankings of 39 dermatology journals using the CCF formula. Along with research and review articles, research letters, editorials and case reports were also included in the denominator value. The CCF was calculated for each journal and then compared with the IF provided by the ISI for 2007. The rank orders of 27/39 journals (69%) were altered by two or more places bi-directionally. Journals with a significant number of editorial and/or letters had a lower CCF. Only 4 of the 39 journals (10%) kept the same rank when evaluated with the new CCF formula. The CCF is a more accurate quantitative representation to use for individual journal comparison. This formula would encourage editors to publish more manuscripts as original or review articles, rather letters or editorials, and eliminate the need for the controversial subjective classification.

Background: Whether the journal impact factor (JIF) indicator reflects the number of citations to an average article of a journal in different subject categories is controversial. We sought to further investigate this issue in general and internal medicine journals.Methods: We selected to evaluate three journals of the above subject category, in each of three different JIF levels (high: 15.5–28.6, moderate: 4.4–4.9 and low: 1.6). Using the Scopus database, we retrieved the original research articles (after detailed screening) and review articles (as classified by Scopus) that were published in the selected journals in 2005 along with the number of citations they received in 2006 and 2007. We pooled the citations for articles of the same type in journals with the same JIF level into distinct variables.Results: There was no marked association between the distribution of citations per article published in general medical journals and their JIF. All distributions studied were skewed to the right (higher number of citations). Specifically, 16–22% of the original research articles accounted for 50% of the total citations to this type of article for all three categories of studied journals; 34–37% of original research articles accounted for 75% of citations. The respective values for review articles were 12–18% and 29–39%.Conclusion: The distribution of citations received by articles published in high, moderate and low impact factor journals in clinical medicine seems similar. The JIF is not an accurate indicator of the citations the average article receives; articles published in low impact factor journals can still be highly cited and vice versa.

ESC Heart Failure (ESC-HF) is an open access journal of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) that published its first issue in 2014, with the help of Wiley Publishing. The journal focuses on basic, clinical, and epidemiological heart failure research. Prof. Stefan D. Anker is Editor-in-Chief and Deputy Editors are Prof. Zoltán Papp (Basic Science) and Prof. Stephan von Haehling (Clinical). In the first year, ESC-HF published two issues, which further increased over time to currently six issues per year (2 in 2014, 4 in 2015/2016/2017, 6 in 2018, 6 expected in 2019). Of course, the number of articles published each year also increased during those years (16 in 2014, 39 in 2015, 38 in 2016, 92 in 2017, 147 in 2018, and 135 in the first 4 issues in 2019). In 2019 we expect to publish about 200 articles in ESC-HF, which is 12 times more than in the beginning year of the journal. We would therefore like to thank all publishing authors that have put their trust into our journal and decided to submit their work to ESC-HF for review. We would also like to thank all reviewers, statisticians, and associate editors, as well as the editorial board. Special thanks go to our editorial office – Monika Diek, Anja Janssen, and Corinna Denecke – without them it would not be possible to publish ESC-HF. Like every year, during summer Thomson Scientific published the new journal impact factors. In Europe and the USA, it is perceived as the most important measure for each journal. Not many people know how this impact factor is calculated: the number of citations of a journal X from the last 2 years are counted for the relevant year and then divided by the number of all original and review articles that were also published in the last 2 years. The formula for calculating the impact factor of journal X in 2018 is shown in Figure 1. This year, ESC-HF received its first impact factor of 3.407, which we think is a great accomplishment, reflecting the hard work everyone involved has put into the journal. If one looks at the best cited papers of the last 3 years, one can see continued interest into the published papers (Tables 1-3 1-75 according to Web of Science76). Of these articles, already 15 have been cited ≥10 times. Many of them are original articles, but also editorials, short communications and reviews are of great interest for the scientific community. In order to estimate how the impact factor of ESC-HF might develop, we compared it to the European Journal of Heart Failure (EJHF, 2018 impact factor 12.129) and European Journal of Preventive Cardiology (EJPC, 2018 impact factor 5.640). Both journals also belong to the ESC Journal Family and have continuously increased their impact factor over the last years (Figure 2). We expect that ESC-HF will equally increase its impact factor over the next years. Looking at the most cited articles of EJHF in the past 3 years, one can see that there is a very broad mix of papers that are of increased relevance to the scientific community: ESC guidelines, HFA practice guidelines, HFA position papers, trial designs, original, and review articles (Tables 4-6).77-151 In EJPC, the most cited articles in the past 3 years were predominatly original and review articles (Tables 7-9).152-226 In total, ESC-HF has published 467 articles so far, EJHF 3717 articles and EJPC 2726 articles. To further look into the best papers ever published in the three different journals, we compared the top 10 ever published papers of all three journals (Tables 10-12).1-3, 26, 27, 77-79, 152, 153, 227-246 The average number of citations of the top 10 cited papes in ESC-HF is 36.1, in EJHF 214.6, and in EJPC 167.7. The best paper so far in ESC-HF received 143 citations,226 in EJHF 624,75 and in EJPC 342.79 Therefore, one can see that all three journals are on a great path that will lead to further success. Conflict of interest: none declared. A full list of references is available at onlinelibrary.wiley.com/doi/10.1002/ejhf.1665.

The ordered assembly and synchronous contraction of striated muscle cells are highly complex processes that depend on the precise spatiotemporal formation of the sarcomeric and extrasarcomeric cytoskeleton alongside with specialized internal membranes that coordinately regulate Ca2+ cycling. The establishment of flexible molecular anchors that withstand stretch, between the contractile cytoskeleton and internal membranes, the superficial cytoskeleton and the sarcolemma, as well as the sarcolemma and the extracellular matrix, allows muscle cells to maintain their structural integrity and contractile activity. Recent advances using state-of-the-art, multidisciplinary, and integrated approaches have yielded a wealth of new information regarding these processes and have highlighted the next challenges for muscle physiologists, biochemists, and biophysicists. In the second volume of our Advances in Muscle Physiology and Pathophysiology special emphasis issue, we continued to solicit original and review articles from leading and emerging scientists who study muscle structure and function and with diverse expertise and interests. A wide array of topics is covered, including, but not limited to, thin and thick filament assembly, regulation of cross-bridges formation, force generation, stress and stretch sensors, and Ca2+ dynamics as well as injury and disease models. As the Editors of this special issue, we are grateful to all the authors who provided either original articles or comprehensive reviews of previous and current literature, making the second volume of this special issue attractive and interesting to a diverse audience of muscle researchers. Similar to our first volume, our aspiration was to include various aspects of muscle physiology and pathophysiology at the molecular, cellular, organ, and organismal levels. We are pleased to see the outcome of our call in the form of this second, special emphasis volume, and as before we expect that it will provide a wealth of information that will further inspire outstanding muscle research.

Análisis de la producción científica de A ctividad D ietética (1997-2007): ¿qué ha sido, qué es y qué se espera que sea la revista científica de la AED-N?

Oxidative stress is implicated in the pathophysiology of a wide variety of neurodegenerative and neurologic disorders. This special issue includes 11 articles that cover different aspects of the importance of oxidative stress in neurotoxicity, neurodegeneration, and potential therapies. Neurotoxicity can occur after exposure to natural or artificial molecules that alter the normal function of the nervous system. The review article by R. Lugo-Huitron et al. focuses on the toxicity of quinolinic acid, an endogenous metabolite of the kynurenine pathway, normally present in the brain and cerebrospinal fluid. This paper discusses the different mechanisms by which quinolinic acid acts as a neurotoxin, such as the activation of N-methyl-D-aspartate (NMDA) receptors, mitochondrial dysfunction, oxidative stress, inflammation, and cell death. B. Wang and Y. Du review the in vitro and in vivo evidence of the neurotoxic effects of cadmium, a heavy metal, in the central nervous system. Several original and review articles examine the role of oxidative stress in diverse neurodegenerative diseases. The original article by C. Savino et al. shows the implication of p66Shc protein and the mitochondrial permeability transition pore pathway in neurodegeneration in a mouse model of autoimmune encephalomyelitis. The role of mitochondria in neurodegeneration is further discussed in two review articles by V. Garcia-Escudero et al. and by Y. Zhao and B. Zhao. These authors present data on the role of mitochondrial dysfunction and oxidative stress in the initiation and progression of Alzheimer's disease, respectively. H. Ariga et al. describe the function of DJ-1 in the pathogenesis of Parkinson's disease. Furthermore, P. Milani et al. summarize the recent literature describing the interaction between Nrf2, a master regulator of the antioxidant response, and DJ-1 and SOD1 proteins and its interest in the development of therapeutic strategies for Parkinson's disease and amyotrophic lateral sclerosis. Two review articles focus on Friedreich's ataxia disease. C. M. Gomes and R. Santos overview the data supporting that oxidative stress is a central feature of this disease. In an opinion paper A. Bayot and P. Rustin present arguments in favor of the hypothesis that the reduction in the expression of PIP5K1B, the gene adjacent to the frataxin-encoding gene, in Friedreich's ataxia patient cells is implicated in disease onset and progression. The antioxidant effect of numerous phytochemicals has long been recognized and has been proposed as an alternative form of treatment, since still no drugs are available that prevent the progression of most neurodegenerative diseases. In an original article, H. Mo et al. describe the potential neuroprotective effect of tea polyphenols in an in vivo subarachnoid hemorrhage mice model. A. Tarozzi et al. present a review of the antioxidant properties of sulforaphane primarily attributed to its ability to activate the Nrf2/ARE pathway. We believe that these contributions provide an updated view on this dynamic field and evidence that supports the importance of considering oxidative stress as a player in neurodegenerative diseases as well as neurotoxicity.

Purpose:To perform an analysis of ophthalmic literature published by the Indian journal of ophthalmology (IJO) between 2005 and 2017 using scientometric techniques.Methods:The bibliographic records of all the literature published in the study period were collected from PubMed and exported as XML into Microsoft access for scientometric analysis. Subspecialty wise distribution across time, type of articles published (original articles, case reports, review articles, editorials, and letter to editor), reference analysis, author productivity analysis and citation analysis were performed as per well-established scientometric methodology.Results:A total of 2,633 papers were published in the IJO during the study period. Articles related to vitreoretinal diseases contributed 23% of all the articles published (n = 598) followed by corneal diseases (n = 313, 12%), and cataract (n = 293, 11%). There were equal numbers of case reports (n = 894, 34%) and original articles (n = 862, 33%) though case reports reduced over time. A total of 5490 unique authors from 64 countries published in the IJO with majority authors (63%) from India. Less than 80% of articles published in the IJO were cited (n = 2051, 78%) by 24,592 articles with retina-related papers contributing 20% of all citations. Original articles had three times more likelihood of being cited compared to case reports.Conclusion:The IJO showed a steady increase in the number of publications from year to year. Papers from the vitreoretinal domain were the commonest and were cited most often. Original articles and case reports contributed equally to the published content though the former were cited much more frequently than the latter.

The 150-year anniversary issue

EDITORIAL article Front. Physiol., 05 November 2012Sec. Computational Physiology and Medicine Volume 3 - 2012 | https://doi.org/10.3389/fphys.2012.00425

Aim: Using fluoride releasing materials such as Glass Ionomer Cement (GIC), can control the demineralization around brackets. In this study, the shear bond strength of resin reinforced GIC modified by Nano-hydroxyapatite (NHA) on ceramic bracket debonding is evaluated. In addition, using full-dimension wire for safe debonding is also examined. Study Design: Original article. Place and Duration of Study: Department of Dentistry, Shahed University, Tehran, IRAN, June 2013. Methods and Material: 80 extracted human premolars received from a clinic were partitioned into 4 groups. Bonding materials used in each group was as follows: Group 1: Transbond XT as a control group, Group 2: Resin Modified GIC (RMGIC), Group 3: RMGIC added 5% NHA and Group 4: RMGIC added 10% NHA. In all groups the enamel was etched with 37% phosphoric acid and ceramic brackets were used. Each group halved into 2 subgroups which just in one of them full dimension wire was employed at the time of debonding. The shear bond strength, Adhesive Remnant Index (ARI) and bracket failure figures were collected for each group. The data was latter analyzed using one-way Analysis Of Variance (ANOVA), Tukey’s HSD (Honestly Significant Difference) Post-hoc Original Research Article Article Annual Research & Review in Biology, 4(10): 1578-1586, 2014 1579 and Kruskal Wallis Test methods. Results: According to ANOVA, RMGIC added 5% NHA has no negative effect while adding 10% NHA lowered the shear bond strength significantly. No bracket failure occurred at debonding, either using or not using full dimension wire. ARI for RMGIC groups were more cohesive than the control group. Conclusion: RMGIC containing 5% NHA contributes bond strength similar to composite resins, in bonding ceramic brackets, while its known demineralization resistance is a favor.

Impact Factors and Prediction of Popular Topics in a Journal.

In 2003 Journal of Physics D: Applied Physics published three sequential review articles on the subject of biomedical applications of magnetic nanoparticles.At that time there was growing interest in basic research on the potential of magnetic nanoparticles in biomedicine, including the appropriate methods to synthesize the particles and how to functionalize them. Following that initial publication the field has burgeoned and is now of a scale that could never have been envisaged in 2003. In the original review articles the authors anticipated applications in three specific technical areas of drug delivery and cell separation, MRI contrast enhancement and hyperthermic heating of biological materials, either for cell destruction or to increase the efficacy of other associated treatments such as chemotherapy. Six years later, significant progress has been made in all three areas, with applications already having been realized. More significantly, in vivo applications of both MRI contrast and hyperthermic cell heating have been achieved in human patients. This rapid progress in such a complex field is due to the need for non-invasive therapies and more effective management of serious conditions than is possible by the simple use of drugs alone. Imaging techniques such as MRI have also improved beyond all expectation and hence the possibility of improved contrast is particularly appealing. However, none of these applications could have been realized without dramatic progress beyond the state of the art in 2003 in the areas of particle synthesis and functionalization. Hence, remarkable progress has been made in all areas of the physics, chemistry and biochemistry of this subject, leading to many publications and perhaps a ten-fold increase in the number of those actively involved in research in this area. In 2003 we were most fortunate to have several expert authors review the subject. Quentin Pankhurst, Puerto Morales and Catherine Berry are now recognized as leaders within their own areas of the field. Because that field is moving rapidly and has now become a major subject of study, we believe that a collection of updated reviews would be highly appropriate and beneficial to the community. We have been fortunate in getting the same authors to provide six-year updates of their original works. This offers continuity and also allows those who may be new to this area to refer back to the original reviews for a full description of the basic science. In the interests of economy and to avoid repetition, this new set of reviews should be read in conjunction with the original works.The Editorial Board of J. Phys D is particularly grateful to the authors for agreeing to write a second work for our journal. We are aware that the production of reviews is an onerous task and acknowledge their efforts in making available such clear and high quality papers. We trust these new works will prove as beneficial to readers and as successful for their authors as were their original reviews.

The aim of this review article is to present the current views and visions of the role of ultrasound (US) in the management of patients with multiple trauma. The article is divided into two parts. Part 1 (US findings and techniques) will mainly deal with the technical aspects of US imaging in trauma patients and is written also for educational purposes. Part 2 (pathophysiology and US imaging in trauma patients) will deal with integration of US in the clinical and pathophysiological management of multiple trauma patients. A non-systematic review of the literature through PubMed search (restricted to the last 10years) of original articles and review articles. 80 publications were selected for Part 1. Of these 80 articles, the author selected 50 according to personal criteria on the basis of their innovative or original contents (48 original articles and 2 literature review articles); 19 articles were furthermore extracted from the references of the selected publications. The information extracted from these 69 publications was organized into sections dealing with different fields of applications of US imaging in multiple trauma patients. US imaging in trauma has evolved from the initial use, i.e., early diagnosis of peritoneal effusion (focused abdominal sonography for trauma), to a wider use known as resuscitative ultrasonography, and is today considered as an extension of physical examination to implement a more effective approach to clinical problems and increase the timeliness and safety of interventions.

Intraoperative Neurophysiological Monitoring (IOMM) has been used worldwide in the attempt to reduce postsurgical neurological deficits, however, most of the publications are from developed countries. There is a global bibliometric analysis of IOMN in spinal surgery, however, the contribution of Latin America (LA) is not mentioned. The aim of this study is to describe scientific productivity, patterns of publications, and thematic trends of IONM in LA. Data was collected using Scopus database, by searching scientific articles with LA affiliation, using 18 keywords. We excluded duplicates, not original articles, reviews, surveys, and articles not related to humans. Articles were analyzed and classified as follows: year of publication, language of the original document, journals metrics, country, IONM modality, etiology, location of surgery, medical specialties, and outcome. Descriptive statistics were used. We obtained 8,699 scientific articles of which 41 scientific articles from 7 LA countries were selected. Mexico has the highest number of publications. In most countries, supratentorial location showed the highest frequency. Somatosensory evoked potentials and electrocorticography were the most performed modalities. Neurosurgery was the most involved specialty of our 41 scientific articles, and 95.1% of these publications concluded that IONM is useful to guide surgical procedures. Mexico and Brazil have led IONM publications in LA. The lower reference in publications of visual evoked potentials and brainstem auditory evoked potentials IONM modalities, could be considered in the future to boost tailored research in LA.

Pressure increases at each competitive career juncture, so it is imperative to get to grips with publishing now. In the United Kingdom (UK), several ‘points’ are awarded to students for publications when applying to the Foundation Programme for their first jobs as junior doctors. The main categories of paper in biomedicine are original articles, review articles, case reports, correspondence articles and miscellaneous articles. Abstracts are found in most articles, except correspondence, as the correspondence format is too terse to warrant them. The majority of articles have a rarely discussed feature: key words. These are written directly after the abstract, and so seems an appropriate place to discuss them. Key words are usually five to ten words that most pertinently summarise student's article. All major pieces of research are presented in original articles and take an accepted format.
