RESUMO

Suicides involving more than one suicide method are termed "complex suicides" and need to be differentiated from murders. Self-immolation is the action of setting fire to oneself and is an infrequent method of suicide method in Western countries. However, burned corpses must be carefully examined because setting fire to a body after death can be a way of covering up a crime. Complex suicides involving self-immolation are rare, but careful analysis is necessary if we are to identify the manner of death. A systematic search of the literature concerning self-incineration in cases of complex suicides was carried out. This covered the age, gender and psychiatric condition of the victims, any history of previous suicide attempts, the existence of suicide notes, evidence of fire accelerants, signs of vital exposure to the fire, toxicology, the other suicide methods used in combination with burning and the characteristics of the burns. 46 cases were found in 22 papers published since 1985, but few of these studies provide any detailed analysis and in several cases many important data were missing. There is, therefore, a need to study this topic and to use an approach based on careful examination of the corpse, detailed investigation of the scene, toxicological examination and an evaluation of the victim's physical and psychiatric state.

RESUMO

OBJECTIVES: Women remain underrepresented on faculties of medicine and the life sciences more broadly. Whether gender differences in self presentation of clinical research exist and may contribute to this gender gap has been challenging to explore empirically. The objective of this study was to analyze whether men and women differ in how positively they frame their research findings and to analyze whether the positive framing of research is associated with higher downstream citations. DESIGN: Retrospective observational study. DATA SOURCES: Titles and abstracts from 101 720 clinical research articles and approximately 6.2 million general life science articles indexed in PubMed and published between 2002 and 2017. MAIN OUTCOME MEASURES: Analysis of article titles and abstracts to determine whether men and women differ in how positively they present their research through use of terms such as "novel" or "excellent." For a set of 25 positive terms, we estimated the relative probability of positive framing as a function of the gender composition of the first and last authors, adjusting for scientific journal, year of publication, journal impact, and scientific field. RESULTS: Articles in which both the first and last author were women used at least one of the 25 positive terms in 10.9% of titles or abstracts versus 12.2% for articles involving a male first or last author, corresponding to a 12.3% relative difference (95% CI 5.7% to 18.9%). Gender differences in positive presentation were greatest in high impact clinical journals (impact factor >10), in which women were 21.4% less likely to present research positively. Across all clinical journals, positive presentation was associated with 9.4% (6.6% to 12.2%) higher subsequent citations, and in high impact clinical journals 13.0% (9.5% to 16.5%) higher citations. Results were similar when broadened to general life science articles published in journals indexed by PubMed, suggesting that gender differences in positive word use generalize to broader samples. CONCLUSIONS: Clinical articles involving a male first or last author were more likely to present research findings positively in titles and abstracts compared with articles in which both the first and last author were women, particularly in the highest impact journals. Positive presentation of research findings was associated with higher downstream citations.

RESUMO

INTRODUCTION: The Journal of the Royal Army Medical Corps (JRAMC) is published with the aim of propagating current knowledge and expertise while also acting as institutional memory for the practice of medicine within the military. This work aimed to examine how the interests of the JRAMC, and by inference the Army Medical Services, have changed over time as reflected by the articles published in the journal. METHODS: A text mining analysis of the titles of all published articles in the JRAMC between 1903 and 2019 was performed. The most commonly used terms were identified and their relative frequency over the decades analysed to identify trends. Article content and contemporary events were compared with the observed trends to identify explanatory events and themes of interest. RESULTS: Medical topics of interest centred around specific infectious diseases, particularly during the early/mid-20th century, and trauma and battle injury. The medical specialties of surgery, anaesthetics and mental health were all well represented in nearly all decades, while primary care only came to prominence as a named specialty from the 1960s onwards. India, France, Egypt and wider Africa were the most commonly cited geographical regions, although there were spikes of interest associated with specific conflicts in the Falklands, Bosnia, Afghanistan and Iraq. CONCLUSION: The interests of the JRAMC have changed considerably over the years primarily driven by the geopolitical interests of Britain-in particular its colonial interests and the conflicts it has been involved in, but also by medical advances seen in contemporary society.

RESUMO

The ideal of a pathology institute consisted of a large autopsy department and a wide collection of specimens for the training of students and clinically active doctors. Additional departments supporting the autopsy department were a chemical and bacteriological laboratory. Other departments were experimental laboratories for biology, immunology, and cell research as well as an animal facility.The main pillar of the training was the understanding of the concept of disease and the development of disease. In this context, the final state of a disease was usually presented in the context of the autopsy. The special contribution of Rudolf Virchow was the additional consideration of cellular changes using microscopic preparations.In contrast, in England and America, clinical care on patients was carried out within the institutes in addition to autopsies. For this purpose, some institutes had their own wards with patient beds. The areas of research were accordingly different. The analysis of journal articles from 1920 to 1940 in two German-language journals, Virchows Archive and Naunyn-Schmiedebergs Archiv für experimentelle Pathologie und Pharmakologie (today: Naunyn-Schmiedeberg's Archives of Pharmacology), and two English-language journals, Journal ofPathology and Bacteriology and American Journal of Pathology, showed different scopes and numbers of publications.On the basis of these publications, it was found that the German journals published a huge variety of diseases, especially series of identical tumors and often the first description of the disease. The British Journal of Pathology published mainly infectious topics and numerous animal experiments. The American journal covered a very broad spectrum of publications, including many on clinically relevant histological techniques.

RESUMO

BACKGROUND: Scientific journals play a fundamental role in the field of health sciences, contributing not only to the dissemination of scientific results but also to the progress of medicine and the training of researchers. The visibility of scientific production in the health area is fundamental to the development of medicine. This study aimed to find the relationship between the editorial quality of a sample of Portuguese scientific health journals and their national and international visibility. METHODS: This is an analytical, transversal and, essentially, quantitative study, based on the analysis of the compliance with Latindex editorial quality criteria in a sample of 46 scientific health journals and ascertaining their national and international visibility. RESULTS: The research showed that the global average of compliance with the criteria by the sample of journals is 91%. The average visibility of the sample is 24%. The hypothesis that the editing criteria are related to the visibility of a sample of Portuguese health journals is confirmed. CONCLUSION: Despite the high rate of compliance with editorial quality criteria, the international visibility of the journals analyzed is still scarce. This reveals the need for the development of complementary competences.

RESUMO

The Mozambican Field Epidemiology and Laboratory Training Program (Moz-FELTP) is a two-year, competency-based post-graduate training and service program designed to build sustainable public health capacity in applied epidemiology. Despite the efforts, Moz-FELTP residents have historically difficulty to publishing their work for a variety of reasons that includes language barriers, lack of writing skills and motivation, limited budgetary support and lack of effective mentorship. This outline the need for different approaches to continuous improving the publication, such scientific writing mentorship for non-English FELTP residents.

RESUMO

OBJECTIVE: To evaluate the methodological quality and reporting quality of Meta-analysis literature published by acupuncture journals included in Chinese Science Citation Database (CSCD), and to provide references and demonstration for relevant studies. METHODS: The Meta-analysis literature published before December 2017 in Chinese Acupuncture & Moxibustion, Acupuncture Research, Journal of Acupuncture and Tuina Science and World Journal of Acupuncture-Moxibustion was retrieved by computer. AMSTAR was used for methodology quality evaluation, and PRISMA was used for reporting quality evaluation. RESULTS: A total of 69 literature was included. Among them, the co-authorship rate was 100% and the cooperation degree was 5.45. The first authors came from 32 institutions, and 29 literature (42.0%) was funded. The cited rate was 98.6%, and averagely each paper was cited 16.3 times. The mean score of methodology quality evaluation was (7.78±1.14) points, including 14 high-quality literature (20.3%), 50 moderate-quality literature (72.5%) and 5 low-quality literature (7.2%). The average score of reporting quality evaluation was (20.33±2.36) points, including 24 relatively complete literature (34.8%), 41 literature with certain defects (59.4%) and 4 literature with serious defects (5.8%). CONCLUSION: The Meta-analysis reports published by acupuncture journals in CSCD have relatively high methodological quality and reporting quality, which could provide evidence for clinical decision making, but still the quality level needed to be further enhanced according to the writing standard of Meta-analysis report. At the same time, the overall level of experimental research should be constantly improved to promote the development of evidence-based research on acupuncture and promote the formation of high-quality evidence.

RESUMO

STUDY DESIGN: A bibliometric review of the literature. OBJECTIVE: The aim of this study was to identify the most highly cited articles relating to imaging of the spine and to analyze the most influential papers and evolving trends in spinal imaging research. SUMMARY OF BACKGROUND DATA: Spinal imaging is being performed with increasing frequency and is an essential step in the diagnosis and treatment planning of spinal pathology. A comprehensive review of the most influential articles in spinal imaging has not been performed, until now. METHODS: A selection of search terms and keywords were inputted into the "Web of Science" database and the most highly cited articles in spinal imaging were selected from high impact factor journals. The top 100 articles were analyzed for year of publication, authorship, publishing journals, institution and country of origin, subject matter, article type, and level of evidence. In addition to total citation count, the number of annual citations was also calculated. Citation counts from Scopus and Google Scholar were also obtained for comparison across other citation index platforms. RESULTS: The most highly cited articles in spinal imaging were published over 30 years, between 1983 and 2013. Total citation count ranged from 98 to 1243 with annual citation count ranging from 3.8 to 91.8. The greatest number of highly cited articles was produced in the United States (n = 49), involved magnetic resonance (n = 73) or multimodal (n = 17) imaging and focused on the lumbar spine (n = 42). The journals that contributed the most articles were Spine and Radiology each publishing 26 articles. CONCLUSION: Our study provided an extensive list of the most historically significant spinal imaging articles, acknowledging the key contributions made to the advancement of this specialist field. LEVEL OF EVIDENCE: 5.

RESUMO

OBJECTIVE: To describe the most-cited articles in public health scientific journals edited in Brazil. METHODS: Articles published between 2008 and 2010 by public health journals edited in Brazil and indexed in the Scopus database were included, and citations received up to five years after publication were ranked. We studied a total of 105 articles, as the last seven articles shared the same number of citations and so were given the same rank. RESULTS: The most-cited articles received a median of 28 citations, and the distribution ranged from 22 to 95 citations. These articles describe advances in the areas of Epidemiology (74%), Health Policies, Planning and Administration (19%), and Social and Human Sciences in Health (7%). Only half mentioned that they have received funding. About 75% of the articles were written by three or more authors and 90%, by authors affiliated to public institutions such as universities and government organizations. Fifteen individuals were responsible for authoring or coauthoring three or more of the 105 articles studied. The journals Cadernos de Saúde Pública, Revista de Saúde Pública, and Ciência & Saúde Coletiva have published the vast majority of the most-cited articles in the area (94%). CONCLUSIONS: In Brazil, the most-cited articles in public health mainly report Epidemiology research, are written by groups of authors and by researchers affiliated to public institutions and are published in journals with a greater impact. Periodical analyses of these data can show potential changes in the characteristics of articles that most attract public health scientists.

RESUMO

The scientific publication landscape is changing quickly, with an enormous increase in options and models. Articles can be published in a complex variety of journals that differ in their presentation format (online-only or in-print), editorial organizations that maintain them (commercial and/or society-based), editorial handling (academic or professional editors), editorial board composition (academic or professional), payment options to cover editorial costs (open access or pay-to-read), indexation, visibility, branding, and other aspects. Additionally, online submissions of non-revised versions of manuscripts prior to seeking publication in a peer-reviewed journal (a practice known as pre-printing) are a growing trend in biological sciences. In this changing landscape, researchers in biochemistry and molecular biology must re-think their priorities in terms of scientific output dissemination. The evaluation processes and institutional funding for scientific publications should also be revised accordingly. This article presents the results of discussions within the Department of Biochemistry, University of São Paulo, on this subject.

RESUMO

OBJECTIVE: This study is aimed to identify predictors of citation rate of original research published in the Canadian Association of Radiologists Journal (CARJ). METHODS: A search of MEDLINE was conducted from January 1, 2000-June 30, 2013 to identify all studies published in the CARJ. Original research studies were included. Reviews, pictorial essays, guidelines, case studies, case series, and original studies with a sample size <10 were excluded. Variables assessed for association with citation rate included number of authors, study design, sample size, multi-institutional study, multi-national study, study type, presence of statistically significant result, presence of funding, and number of references. Statistical analysis was completed using linear regression and Pearson correlation coefficients (r). RESULTS: A total of 714 studies were published in CARJ, of which 181 were original research publications that were cited a total of 1517 times. Twelve original research studies were uncited, while the most-cited one was cited 58 times. Sample size (r = 0.177, P = .017) and number of references (r = 0.164, P = .028) demonstrated statistically significant weak positive correlations with citation rate. Number of authors, study design, setting, statistically significant results, and funding were not associated with citation rate. CONCLUSION: Only a very small number of original research studies published at the CARJ remained uncited 5 or more years after the publication. Sample size and number of references were identified as significant, but weak predictors of citation rate in CARJ.

RESUMO

The deep sea remains the least known biome. Despite this fact, anthropic activities have affected these regions in various ways. The objective of this study was to outline the scientific production scenario based on deep sea research and to analyze trends present in the literature. For this, the bibliographical resources available from the Web of Science (WoS) were surveyed. Between 1987 and 2016, 11,079 articles on the deep sea were published. Growth was over 100% from the first to second decade and 75% from the second to third. The most productive countries were the USA, Germany, France, England and Japan. Of the 404 journals that published articles on the deep sea, 10% accounted for approximately 60% of the total published articles. The keyword with the highest occurrence was "diversity". In the first two decades, the keywords with the greatest "strength" were related to research on mining, especially for hydrocarbons. The description of new species and the analysis of the effects of climate change appear to be emerging trends in deep sea research. Mining continues to be primarily responsible for driving the development of deep sea research.

RESUMO

AIMS: Traditional journal level metrics, as the impact factor or Scimago journal ranking indicator (SJR) measure the impact of research on other researchers, but fail to assess the reach of these publications among wider audiences. This study aims to assess the correlation between SJR and metrics of presence on social networks of endocrinology journals. MATERIALS AND METHODS: Journals within the area of endocrinology, diabetes and metabolism were identified from the electronic portal Scimago Journal and Country Rank, and their metrics based on the number of citation collected. Different metrics of the presence on social networks, such as the number of followers and number of tweets, were assessed. The correlation between both metrics was evaluated by calculating the Spearman correlation coefficient. RESULTS: Of the 232 journals evaluated, 28 (12.1%) had social networks. The median SJR (1.53 vs 0.60, p < 0.01), and H index (58.5 vs 22, p < 0.01) were significantly higher among journals with social networks. The correlation between the number of followers on twitter and the SJR was moderate (r = 0.60, p < 0.05), and it was better in journals with more than 500 publications in the last 3 years (r = 0.85, p < 0.05). The number of tweets also had a moderate correlation with the SJR (r = 0.59, p < 0.05) CONCLUSIONS: Our results suggest that the dissemination of research on social networks is moderately related to the traditional metrics of impact. Both types of metrics offer complementary information: while metrics based on social media may not perfectly predict the impact a scientific journal, it does have the advantage of immediacy.

RESUMO

Objetive: To describe the characteristics of the scientific production of midwives in Latin American obstetrics and gynecology journals indexed to Scopus during the period 2011 to 2016. Methods: This paper reports a descriptive bibliometric study, with intentional non-probabilistic sampling. We analyzed articles of research papers published by midwives in medical specialty journals in obstetrics and gynecology of Latin America indexed to Scopus, in the 2011 to 2016 period. Results: We found eight obstetrics and gynecology journals in Latin America indexed in Scopus. There were 1,696 articles published between 2011 and 2016, of which 4.9% were authored or co-authored by midwives. Of these publications, 93.8% were related to topics of the specialty, 62.5% had midwives as corresponding authors, 64.1% of papers were in Spanish, only 3.1% were published in English, and 57.8% of midwives worked in Chile at the time of publication. In 2016, there was one-fifth the number of publications compared to 2012. Conclusions: We found little scientific production by midwives in Latin American obstetrics and gynecology journals indexed in Scopus. Strategies that encourage and allow research and scientific production by midwives are needed.
