RESUMO

Introduction: Research is essential in all areas of health development. However, medical students and residents frequently lack the time and training on performing research. This is especially prevalent in resource-limited settings. We aimed to compare the word counts of undergraduate and postgraduate dissertations with published projects in Rwanda, and to identify the proportion of postgraduate pediatric research projects that have been published since 2012. Methods: Retrospective, cross-sectional study of undergraduate and postgraduate research dissertations at the University of Rwanda. Dissertations were then compared to randomly selected published papers of Rwandan research. Each IMRaD (Introduction, Methodology, Results and Discussion) section word count was compared using Student's t-test. Results: 19/190 (10%) undergraduate dissertations and 22/41 (54%) postgraduate dissertations, were available in electronic format for word-count analysis. The mean total word count for postgraduate dissertations (5163 words) was significantly longer (p<0.001) than the randomly selected peer-reviewed journal articles (2959 words). Each section of the IMRaD structure of postgraduate dissertations was significantly longer than those of the control group. Undergraduates used a similar number of words to published papers, but used significantly more tables and figures. Of the 41 postgraduate dissertations, only four (10%), were published in peer-reviewed journals. Conclusion: This is the first study to assess the writing style of Rwandan medical students and pediatric postgraduate residents. A simple step to increase dissemination of research findings would be for institutions to modify academic regulations so that students write-up in manuscript form rather than dissertation format.

RESUMO

OBJECTIVE: To determine the history of malpractice literature using forensic science based on a bibliometric and graph theory. METHODS: Documented data were retrieved from the Web of Science Core Collection of Clarivate Analytics on February 22, 2019. We selected articles for the years 1975-2018 from among documents concerning malpractice in the "Medicine, Legal" section and the Science Citation Index Expanded and the Social Sciences Citation Index. Descriptive statistics and co-occurrence analyses were performed using Microsoft Excel 2016, Gephi 0.9.2, and VOSviewer 1.6.10 software. RESULTS: In all, 379 papers and 3160 citing articles were retrieved. The most active publication year was 2013. Relative growth rate showed no malpractice explosion during the study period. Full articles comprised 83.11% of all papers. There were marked differences between the number of publications during the first 21 years and the last 23 years. More studies were published in the United States than in other countries and regions, but malpractice research has diminished during the most recent 3 years. Journal of Law, Medicine and Ethics contributed the most to the field, with 51 documents. The journal with the highest impact factor, however, was Forensic Science International: Genetics. B. Madea topped the list of authors with the highest number of documents. Three clusters were identified, led by authors C. Terranova, B. Madea, and T.A. Brennan, respectively. The malpractice topics that received the most attention were malpractice claims, the types of malpractice, and the causes of medical malpractice. Our study of the citing papers also provided interesting results. CONCLUSION: This bibliometric analysis indicated that studying the field of medical malpractice was poor during 1975-2018. United States was the most prolific country, and B. Madea published more documents in the field. The studies in Medicine, Legal mostly focused on the claims, appraisement methods, and causes of medical malpractice. In the future, forensic scientists should pay more attention to medical malpractice.

RESUMO

During 2012-2018 in the Russian Federation, pursuant to Presidential Decree No. 599 of 05.07.2012, a set of state support measures was implemented aimed at increasing the specific gravity of Russian publications indexed in international databases. The national project 'Science' (NPS) designed to realize the goals set by Presidential Decree No.204 of 05.07.2018 'On the National Goals and Strategic Tasks for Development of the Russian Federation until 2024' continues and develops the theme of increasing the publication activity of the Russian Federation in the internationalized space. One of the six NPS targets is 'The place of the Russian Federation in terms of specific gravity in the total number of articles in areas defined by the priorities of scientific and technological development in publications indexed in international databases'. The purpose of this study was to evaluate the basic value of this indicator for biomedical disciplines related to the priority direction (paragraph 20c) of the Strategy for Scientific and Technological Development of the Russian Federation. We compared volumes of publication flows of the Russian Federation in 20 biomedical disciplines with a similar indicator of countries ranked fifth in the number of publications on the subject area under consideration, indexed in the Web of Science Core Collection (WoS CC). A 5-10 fold lag of the Russian Federation was recorded for the most part of the priority areas in the field of biomedicine identified by the NTS passport. The impact of public policy measures aimed at increasing the national biomedical publication stream for the period of 2012-2018 was estimated as insufficient to meet the considered NTS target.

RESUMO

OBJECTIVE: Most studies of tuberculosis originate from high-income countries with a low incidence of tuberculosis. A review of the scientific production on tuberculosis in Latin American countries, most of which are low- or middle-income countries (some with high or intermediate tuberculosis incidence rates), would improve the understanding of public health challenges, clinical needs, and research priorities. The aims of this systematic review were to determine what has been published recently in Latin America, to identify the leading authors involved, and to quantify the impact of international collaborations. METHODS: We used PubMed to identify relevant manuscripts on pulmonary tuberculosis (PTB), drug-resistant tuberculosis (DR-TB), or multidrug-resistant tuberculosis (MDR-TB), published between 2013 and 2018. We selected only studies conducted in countries with an annual tuberculosis incidence of ≥ 10,000 reported cases and an annual MDR-TB incidence of ≥ 300 estimated cases, including Brazil, Peru, Mexico, Colombia, and Argentina. Articles were stratified by country, type, and topic. RESULTS: We identified as eligible 395 studies on PTB and 188 studies on DR/MDR-TB-of which 96.4% and 96.8%, respectively, were original studies; 35.5% and 32.4%, respectively, had an epidemiological focus; and 52.7% and 36.2%, respectively, were conducted in Brazil. The recent Latin American Thoracic Association/European Respiratory Society/Brazilian Thoracic Association collaborative project boosted the production of high-quality articles on PTB and DR/MDR-TB in Latin America. CONCLUSIONS: Most of the recent Latin American studies on tuberculosis were conducted in Brazil, Mexico, or Peru. Collaboration among medical societies facilitates the production of scientific papers on tuberculosis. Such initiatives are in support of the World Health Organization call for intensified research and innovation in tuberculosis.

RESUMO

In accordance with the Physician Payment Sunshine Act, all industry payments to physicians in the United States have become publicly available. Previous research has indicated that orthopedic surgeons receive the greatest amount of industry compensation compared with other surgical subspecialists. However, the relationship between this compensation and research productivity is less clear. This study sought to investigate the relationship between consulting fees paid to orthopedic surgeons and academic productivity. Using the Centers for Medicare & Medicaid Services Open Payments Database, this study identified 2555 orthopedic surgeons who received at least one industry consulting fee in 2015. Physicians who received total consulting fees of at least $20,000 (US) were stratified into the high payment group. The number of publications and the h-index for each physician were used as metrics of scholarly impact. Mean publication number and h-index for the high payment group were compared with all other physicians in the sample using an independent-samples t test. A total of 2555 orthopedic surgeons received consulting payments totaling $62,323,143 in 2015. The mean consulting payment was $24,393 (SD, $45,465). The publication number was greater for the high payment group (mean, 61.6; SD, 135.6) compared with all other physicians in the sample (mean, 36.1; SD, 95.6). Additionally, the mean h-index for the high payment group was 13.7 (SD, 14.3) compared with 10.0 (SD, 11.6) for all other orthopedic surgeons. These findings indicate that the orthopedic surgeons who receive more in industry consulting fees are also those who contribute most substantially to the body of orthopedic literature.

RESUMO

OBJECTIVE: Web-based platforms have revolutionized the ability for researchers to perform global survey research. Methods to incentivize participation have been singularly focused on European and North American participants with varied results. With an ever increasing proportion of biomedical research being performed in non-western countries, assessment of novel methods to improve global survey response is timely and necessary. To that end, we created a three-arm nested randomized control trial (RCT) within a prospective cohort study to assess the impact of incentives on survey responsiveness in a global audience of biomedical researchers. RESULTS: Email invitations were sent to authors and editors involved in online publishing totaling 2426 participants from 111 countries. Overall we observed a 13.0% response rate: 13.3% for the control group, 14.4% for a group entered to win a gift card, and 11.1% for a group whose participation lead to donation to charity (p = 0.17). Year of publication nor country impacted response rate. Within subgroups, editors were significantly less likely to respond to the survey as compared to authors (6.5% vs. 18.9%; p-value < 0.01). With power to detect a 4.8% difference among groups, we could not detect an impact of incentives on global survey response.

RESUMO

OBJECTIVE: The objective of this study was to explore the evolution footprints of simulated driving research in the past 20 years through rigorous and systematic bibliometric analysis, to provide insights regarding when and where the research was performed and by whom and how the mainstream content evolved over the years. METHODS: The analysis began with data retrieval in Web of Science with defined search terms related to simulated driving. BibExcel and CiteSpace were employed to conduct the performance analysis and co-citation network analysis; that is, probe of the performance of institutes, journals, authors, and research hotspots. RESULTS: A total of 3,766 documents were filtered out and presented an exponential growth from 1997 to 2016. The United States contributed the most publications as well as international collaborations followed by Germany and China. In addition, several universities in The Netherlands and the United States dominated the list of contributing institutes. The leading journals were in transportation and ergonomics. The leading researchers were also recognized among the 8,721 contributing authors, such as J. D. Lee, D. L. Fisher, J. H. Kim, and K. A. Brookhuis. Finally, the co-citation analysis illuminated the evolution of simulated driving research that covered the following topics roughly in chronological order: task-induced stress, drivers with neurological disorders, alertness and sleepiness while driving, trust toward driving assistance systems, driver distraction, the effect of drug use, the validity of simulators, and automated driving. CONCLUSIONS: This article employed bibliometric tools to probe the contributing countries, institutes, journals, authors, and mainstream hotspots of simulated driving research in the past 20 years. A systematic bibliometric analysis of this field will help researchers realize the panorama of global simulated driving and establish future research directions.

RESUMO

PURPOSE: To investigate whether publishing research is an important aspect of medical careers, and how it varies by specialty and rural or metropolitan location. METHODS: Annual national panel survey (postal or online) of Australian doctors between 2008 and 2016, with aggregated participants including 11 263 junior doctors not enrolled in a specialty ('pre-registrars'), 9745 junior doctors enrolled as specialist trainees, non-general practitioner (GP) ('registrars') and 35 983 qualified as specialist consultants, non-GP ('consultants'). Main outcome was in agreement that 'research publications are important to progress my training' (junior doctors) or 'research publications are important to my career' (consultants). RESULTS: Overall, the highest proportion agreeing were registrars (65%) and pre-registrars (60%), compared with consultants (36%). After accounting for key covariates, rural location was significantly associated with lower importance of publishing research for pre-registrars (OR 0.69, 95% CI 0.61 to 0.78) and consultants (OR 0.69, 95% CI 0.63 to 0.76), but not for registrars. Compared with anaesthetics, research importance was significantly higher for pre-registrars pursuing surgery (OR 4.46, 95% CI 3.57 to 5.57) and obstetrics/gynaecology careers, for registrars enrolled in surgery (OR 2.97, 95% CI 2.34 to 3.75) and internal medicine training, and consultants of internal medicine (OR 1.84, 95% CI 1.63 to 2.08), pathology, radiology and paediatrics. CONCLUSIONS: This study provides new quantitative evidence showing that the importance of publishing research is related to medical career stages, and is most important to junior doctors seeking and undertaking different specialty training options. Embedding research requirements more evenly into specialty college selection criteria may stimulate uptake of research. Expansion of rural training pathways should consider capacity building to support increased access to research opportunities in these locations.

RESUMO

In recent years, the algae-bacteria symbiotic system has played a significant role in the sustainable development of wastewater treatment. With the continuous expansion of research outputs, publications related to wastewater treatment via algal-bacterial consortia appear to be on the rise. Based on SCI-EXPANDED database, this study investigated the research activities and tendencies of algae-bacteria symbiotic wastewater treatment technology by bibliometric method from 1998 to 2017. The results indicated that environmental sciences and ecology was the most productive subject categories, followed by engineering. Bioresource Technology was the most prominent journal in this field with considerable academic influence. China (146), USA (139) and Spain (76) had the largest amount of publications. Among them, USA was in a leading position in international cooperation, with the highest h-index (67) in 79 countries/territories. The cooperation between China and USA was the closest. The cooperative publishing rate of the Chinese Academy of Sciences was 83.33%, but most of them were in cooperation with domestic institutions, while international cooperation was relatively limited. Methane production, biofuel production, and extracellular polymeric substance were future focal frontiers of research, and this field had gradually become a multi-perspective and inter-disciplinary approach combining biological, environmental and energy technologies.

RESUMO

BACKGROUND: Discrepancies between pre-specified and reported outcomes are an important source of bias in trials. Despite legislation, guidelines and public commitments on correct reporting from journals, outcome misreporting continues to be prevalent. We aimed to document the extent of misreporting, establish whether it was possible to publish correction letters on all misreported trials as they were published, and monitor responses from editors and trialists to understand why outcome misreporting persists despite public commitments to address it. METHODS: We identified five high-impact journals endorsing Consolidated Standards of Reporting Trials (CONSORT) (New England Journal of Medicine, The Lancet, Journal of the American Medical Association, British Medical Journal, and Annals of Internal Medicine) and assessed all trials over a six-week period to identify every correctly and incorrectly reported outcome, comparing published reports against published protocols or registry entries, using CONSORT as the gold standard. A correction letter describing all discrepancies was submitted to the journal for all misreported trials, and detailed coding sheets were shared publicly. The proportion of letters published and delay to publication were assessed over 12 months of follow-up. Correspondence received from journals and authors was documented and themes were extracted. RESULTS: Sixty-seven trials were assessed in total. Outcome reporting was poor overall and there was wide variation between journals on pre-specified primary outcomes (mean 76% correctly reported, journal range 25-96%), secondary outcomes (mean 55%, range 31-72%), and number of undeclared additional outcomes per trial (mean 5.4, range 2.9-8.3). Fifty-eight trials had discrepancies requiring a correction letter (87%, journal range 67-100%). Twenty-three letters were published (40%) with extensive variation between journals (range 0-100%). Where letters were published, there were delays (median 99 days, range 0-257 days). Twenty-nine studies had a pre-trial protocol publicly available (43%, range 0-86%). Qualitative analysis demonstrated extensive misunderstandings among journal editors about correct outcome reporting and CONSORT. Some journals did not engage positively when provided correspondence that identified misreporting; we identified possible breaches of ethics and publishing guidelines. CONCLUSIONS: All five journals were listed as endorsing CONSORT, but all exhibited extensive breaches of this guidance, and most rejected correction letters documenting shortcomings. Readers are likely to be misled by this discrepancy. We discuss the advantages of prospective methodology research sharing all data openly and pro-actively in real time as feedback on critiqued studies. This is the first empirical study of major academic journals' willingness to publish a cohort of comparable and objective correction letters on misreported high-impact studies. Suggested improvements include changes to correspondence processes at journals, alternatives for indexed post-publication peer review, changes to CONSORT's mechanisms for enforcement, and novel strategies for research on methods and reporting.

RESUMO

The impact factor can undervalue the importance of smaller, specialized journals, and no single metric can serve as a perfect assessment of a journal's value or worth. This article provides a brief overview of various publication metrics, including the Scopus CiteScore, Eigenfactor®, and Altmetric attention score, using examples from the Oncology Nursing Forum. It also addresses the use of the Oncology Nursing Forum as a resource for research and answering clinical questions.

RESUMO

PURPOSE: To analyse the coverage and main bibliometric indicators of ANALES DE PEDIATRÍA in Scopus and Science Citation Index Expanded of the Web of Science (SCIE) databases. MATERIAL AND METHOD: The evolution of the journal production was identified according to the document types, collaboration indexes between authors and institutions, and citations, and impact indicators (number of citations, impact factor, 5-years impact factor and without self-citations, Scimago Journal Rank, quartile, h index and most cited works). RESULTS: A total of 10,128 papers were included in Scopus (a mean of around 225 per year) and 1,861 in SCIE (a mean of around 207 per year). The index of collaboration was 4.4 for authors and 2 for institutions. There was international collaboration in 4.2% of the papers. The number of citations received in Scopus (619) exceeded the number of citations received in SCIE (385) by 234. The mean number of citations per paper was lower in SCIE (2.27 in Scopus compared to 1.5 in SCIE). The h index was 18 in Scopus and 14 in SCIE. CONCLUSIONS: Discrepancies were observed in the indicators obtained in both databases due to the different indexation policies, coverage, and classification methods of the papers. The number of citations, the mean number of citations per work, and the h index were higher in Scopus due to the longer life of the journal in that database. There is a positive evolution of the impact factor in SCIE, of the impact factor excluding self-citations, and of the 5-year impact factor.

RESUMO

Academic output is just one aspect of a successful career as a plastic surgeon. However, for those with a strong interest in academia, the academic output of a department will likely be a key factor when deciding how to rank jobs. The aim of this study was to quantify and rank the academic output of plastic surgery units across the UK and Ireland. The Institute for Scientific Information (ISI) Web of Science Bibliometric analysis tool was used to collate cumulative (1950-2016), 10 year (2006-2016) and 3 years (2013-2015) research output data for plastic surgery units in the UK and Ireland. Sixty-six plastic surgery units were identified. Departments were ranked for each time period according to the number of papers produced, number of citations (Nc) and h-index (a measure of the impact of scientific output). The top 3 departments for number of papers in the last 10 years were The Royal Free Hospital, London (226) Broomfield Hospital, Chelmsford (218), and Morriston Hospital and Swansea (188). The top 3 for h-number were The Royal Free Hospital (21) Wythenshawe Hospital, Manchester (18) and Morriston Hospital (17). Academic output varies across plastic surgery units in the UK and Ireland. A number of departments have consistently maintained high academic outputs across the years and will be of interest to surgeons hoping to pursue a career in academia.

RESUMO

Electronic cigarettes are at the center of a public health policy debate which leverages scientific publications. This study characterizes e-cigarette publication trends over the past 15 years via a bibliometric analysis. Scopus was searched for "electronic cigarette", "e-cig", "e-cigarette", "vape", "vaping", "juul", or "electronic nicotine delivery system" between 2003⁻2018. Data included Hirsch index, document type and frequency, and publications by institution, journal, and country. VOSviewer was used to visualize authorship network maps. A total of 4490 e-cigarette publications were identified, most (62.8%) being articles. After 2009, the annual growth rate for e-cigarette publications was the largest in 2014. The annual growth rate was nearly flat in 2017 but increased in 2018. The U.S. produced 51.6% of publications. Annual National Institutes of Health NIH funding for tobacco research mapped closely with the annual volume of e-cigarette publications. Author network analyses illustrated investigator collaborative patterns. The frequency of e-cigarette publications increased significantly in the past decade. A strong relationship of NIH funding for tobacco research and e-cigarette publications demonstrates the importance of e-cigarettes in tobacco research.

RESUMO

Electronic books are a substantial component of many academic libraries. Many libraries aim to make their collections easily discoverable through curated lists. The authors' library devised a methodology to identify and flag all e-books authored by our institution's faculty using MARCEdit and Microsoft Access. We highlight some of the challenges in gathering a comprehensive list of titles, the process of formulating such a list, and the measures needed to actively curate e-books by faculty for both content already in the collection and newly published titles.

RESUMO

OBJECTIVE: To investigate endometrial scratch injury (ESI) as an intervention to improve IVF outcome in women undergoing a first ET. DESIGN: Systematic review and meta-analysis. SETTING: Not applicable. PATIENT(S): Infertile women undergoing a first fresh/frozen embryo transfer. INTERVENTION(S): We included published and unpublished data from randomized controlled trials in which the intervention group received ESI and controls received placebo or no intervention. Pooled results were expressed as relative risk (RR) with 95% confidence interval (CI). The review protocol was registered in PROSPERO to start the data extraction (CRD42018087786). MAIN OUTCOME MEASURE(S): Ongoing pregnancy/live birth rate (OPR/LBR), clinical pregnancy rate (CPR), multiple pregnancy rate (MPR), miscarriage rate (MR), and ectopic pregnancy rate (EPR). RESULT(S): Seven studies were included (1,354 participants). We found a nonsignificant difference between groups in terms of OPR/LBR, CPR, MR, MPR, and EPR. Subgroup analysis found that ESI on the day of oocyte retrieval (achieved by a Novak curette) reduced OPR/LBR (RR 0.31, 95% CI 0.14-0.69) and CPR (RR 0.36, 95% CI 0.18-0.71), whereas ESI during the cycle preceding ET (performed through soft devices) had no effect on OPR/LBR and CPR. No difference in the impact of ESI was observed between fresh and frozen embryo transfer. CONCLUSION(S): Current evidence does not support performing ESI with the purpose of improving the success of a first ET attempt.

RESUMO

OBJECTIVE: To determine what factors of published urology research articles are associated with future citations. METHODS: We identified all primary research articles published between 1997 and 2007 in Journal of Urology, British Journal of Urology International, Urology, and European Urology. Only 50 articles in this period had accrued 0 or 1 citation in a 10-year period following publication. We compared the characteristics of the articles in the low citation cohort to the 50 articles with the highest number of citations from the same journals and time period. Student's t tests, Wilcoxon rank-sum tests, chi-squared tests, and Fisher's exact tests were used to analyze the data with predetermined level of significance set to P < .05. RESULTS: There were many significant differences between the 2 cohorts. When compared to the cohort of articles with 0 or 1 citation, highly cited articles were significantly more likely to be a clinical study, multi-institutional and multinational effort, and related to the field of urologic oncology. They were also significantly more likely to have a larger sample size, a statistically significant primary finding, more authors, more references, and more tables, as well as longer title, abstract, and overall manuscript word counts. CONCLUSION: Very few articles published in the major urology journals accrued 0 or 1 citation over a 10-year period. This suggests that the vast majority of articles selected for publication are used for further future research. Nevertheless, there were distinct differences between the 2 cohorts, showing that certain factors are associated with articles being cited more frequently.
