Tasa de publicaciones de trabajos presentados sobre artritis reumatoidea en congresos de Reumatología / Publication rates of papers on rheumatoid arthritis submitted to Congresses of Rheumatology

Resumen Introducción: se publica una minoría de todos los trabajos presentados en los Congresos Argentinos de Reumatología (CAR). Objetivos: analizar los temas de estudio (TDE) de los trabajos sobre artritis reumatoidea (AR) presentados en los CAR y su tasa de publicación. Materiales y métodos: se analizaron todos los resúmenes sobre AR, como motivo primario de estudio, presentados en los CAR entre 2008 y 2017. Se agruparon según TDE, y se determinaron los TDE repetidos definidos como, al menos, dos estudios similares presentados sobre el mismo tema. Se determinó la tasa de publicación, el número de estudios similares por TDE, el número de centros participantes y el número de pacientes estudiados. Resultados: sobre 346 trabajos presentados, 51 (14,7%) fueron publicados. Se publicaron 14 (11,9%) de los 118 estudios sobre TDE repetidos versus 37 (16,2%) del resto de los TDE (p=0,4). Los trabajos sobre TDE repetidos no incluyeron más pacientes ni involucraron a un número mayor de centros. Se encontraron 13 TDE repetidos con al menos tres estudios similares y ningún estudio publicado. Conclusiones: solo una minoría de los trabajos sobre AR se publicó. Un tercio de los trabajos presentados en los CAR correspondió a TDE repetidos, que no mejoraron la tasa de publicación.

Abstract Introduction: only a few articles submitted to the Argentine Congress of Rheumatology (ACOR) are published. Objectives: to analyse the topics of study (TOS) and the publication rate of articles on rheumatoid arthritis (RA) submitted to the ACOR. Materials and methods: every abstract submitted to the ACOR between 2008 and 2017, whose primary research subject was RA, was analyzed and sorted according to TOS. Repeated TOS, defined as at least two similar studies on the same topic, were identified. The publication rate and the number of similar studies according to TOS, participating centers, and patients were determined. Results: out of 346 articles submitted, 51 (14.7%) were published. Fourteen (11.9%) of the 118 studies on repeated TOS were published vs. 37 (16.2%) of the rest of the TOS (p: 0.4). The articles on repeated TOS neither included more patients nor involved a higher number of centers. Thirteen repeated TOS with at least three similar studies, but no published articles were identified. Conclusions: only a few articles on RA were published. One third of the studies submitted to the ACOR are repeated TOS, a fact that does not improve the publication rate.

Discrepancies of abstracts presented in coloproctology congresses and later publish as full manuscripts: a Brazilian perspective

Introduction: The purpose of this retrospective bibliometric study was to assess the discrepancies between coloproctology surgery meeting abstracts and subsequent full-length manuscript publications. Methods: Abstracts presented at the Brazilian Congress of Coloproctology Surgery from 2015 to 2019 were compared with matching manuscript publications. Discrepancies between the abstract and therefore the subsequent manuscript were categorized as major (changes within the purpose, methods, study design, sample size, statistical analysis, results, and conclusions) and minor (changes within the title, authorship, and number of female authors) variations. Results: The conversion rate of abstracts in published manuscripts was 6,9% (121 abstracts). There were inconsistencies between the study title (66,1%), authorship (69,5%), study design (3,3%), sample size (39,2%), statistical analysis (24,8%), results (25,6%), and conclusions (12,4%) of manuscripts compared with their corresponding meeting abstracts. Conclusion: As changes occur before manuscript publication of coloproctology surgery meeting abstracts, caution should be exercised in referencing abstracts or altering surgical practices based on abstracts content.

An American and Brazilian perspective on abstracts presented in coloproctology conferences converted into published manuscripts

Introduction: The presentation of abstracts in a congress is an important step for the dissemination of scientific information. The American Congress of Coloproctology is promoted by the American Society of Colon & Rectal Surgeons (ASCRS), and it is the largest in number of participants within the specialty, followed by the Brazilian Congress of Coloproctology. The present study aims to evaluate variables related to the quality of the scientific production of the abstracts presented in these two events and their conversion rate to published manuscripts. Materials and Methods: The present bibliometric study assesses secondary data from the review of abstracts presented in these 2 important conferences in 2016, followed by a research of the publications from these congress presentations. Results: The total number of abstracts evaluated was 854. The rate of articles containing statistical analyses was of 73.7% in the American congress, and of 34.1% in the Brazilian congress. Multicentric studies were more prevalent in the American congress (23.1%). Regarding study design, the most common were case reports in the Brazilian (44.8%) congress and retrospective studies in the American congress (67.7%). As for the works presented, the rate of conversion into full manuscripts in the American congress was of 24.2% compared with 10.6% in the Brazilian congress. Most papers from the American congress (93.7%) have citations compared with 68.6% of the other event evaluated. Conclusion: The scientific performance demonstrated by the conversion rate of abstracts into publications is below ideal, mainly in relation to the Brazilian meeting; yet, there were significant differences between the two events in terms of the profile of the presentations and several variables analyzed.

Bibliometric analysis and conversion rate of abstracts presented at the Brazilian Congress of Coloproctology into publication of full articles / Análise bibliométrica e taxa de conversão de resumos apresentados no Congresso Brasileiro de Coloproctologia em publicação de artigos completos

ABSTRACT Introduction: the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates. Methods: Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors. Results: 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones. Conclusion: the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

RESUMO Introdução: a apresentação de pesquisas em um congresso é meio interessante para disseminação científica, porém apenas com a publicação em revista indexada é que os dados se tornam acessíveis e disseminados. A taxa de conversão em artigos publicados de resumos apresentados em congressos é um indicador para avaliar a qualidade científica de seus eventos. O objetivo deste estudo é avaliar características bibliométricas dos resumos apresentados no Congresso Brasileiro de Coloproctologia e determinar os fatores que afetam as taxas de publicação. Métodos: avaliação retrospectiva de todos os resumos apresentados nos Congressos Brasileiros de Coloproctologia dos anos de 2015 a 2019. Análise de múltiplas bases de dados para estimar a taxa de conversão dos trabalhos apresentados, assim como variáveis associadas à conversão dos resumos em manuscritos completos através de análises bivariadas e multivariadas desses preditores. Resultados: foram analisados 1756 resumos. A maioria dos estudos são retrospectivos, séries ou relatos de casos e até experiência pessoal. A taxa de conversão foi de 6,9%. A presença de análise estatística foi o dobro para os resumos publicados frente aos não publicados. Conclusão: os dados apresentados demonstram uma baixa produtividade científica da especialidade, já que as pesquisas realizadas não são publicadas, em sua maioria, como manuscritos completos. Os fatores preditores de publicação dos resumos foram: estudos multicêntricos, estudos contendo análise estatística, desenhos de estudo de maior nível de evidência e estudos premiados pelo congresso.

How to write medical abstracts? The rhetorical structure and phrases used in Epidemiology / Como escrever resumos da área médica? A estrutura retórica e frases usadas na Epidemiologia

Introduction: Abstracts are critical in medical contexts. They contain formulaic building blocks called Lexical Frames (LFs), which are high-frequency word sequences with variable slots that can be formed around collocation nodes. LFs are abundant in written academic discourse, and , for this reason, have great importance for the production of abstracts. Extensive research has been conducted on formulaic language, especially on medical genres. Fewer studies, however, have focused on LFs from specialty-specific corpora (.e.g., epidemiology) and their relationship with the rhetorical structure of abstracts. Objective: This study aims to fill this gap by describing the structure of epidemiology abstracts, presenting their rhetorical functions, and identifying the LFs that linguistically realize these functions to help researchers write more conventional abstracts. Methods: We put together three corpora of abstracts in the field, published in English in peer-reviewed journals, and combined genre analysis and Corpus Linguistics principles to identify the linguistic realizations of the rhetorical functions in the texts. First, the rhetorical structure was described; then, the LFs were identified and analyzed. Results: 92% of the texts follow a pre-established pattern, whose structure consists of five to nine sections. Eight saliently frequent nodes (study, result, method, conclusion, review, analysis, patients, and findings) around which the LFs are constructed were identified. Conclusion: Even though both the content and function words that make up the LFs show some variation, it is possible to notice that the LFs elicited typify the linguistic realizations of the corresponding sections' rhetorical functions and, thus, are suitable to the observation of a pattern. For that reason, the data obtained in this study were used to inform the creation of a support framework for the writing of specialty-specific medical abstracts.

Introdução: Resumos são cruciais em contextos médicos. Tais textos contêm blocos formulaicos do discurso acadêmico, denominados Estruturas Lexicais (ELes), sequências de palavras de alta frequência compostas de termos variáveis, organizados a partir de nódulos colocacionais. Estruturas Lexicais são abundantes no discurso acadêmico escrito, tendo grande importância para a produção de resumos. Extensas pesquisas já foram conduzidas acerca de linguagem formulaica, especialmente em gêneros médicos. Poucos estudos se concentraram em Estruturas Lexicais em corpora de especialidades (como epidemiologia) e sua relação com a estrutura dos resumos. Objetivo: Este estudo busca suprir a lacuna apontada descrevendo a estrutura dos resumos de epidemiologia, apresentando suas funções retóricas e identificando as Estruturas Lexicais que realizam essas funções, para promover escrita de resumos mais convencionais. Métodos: Compilamos três corpora de resumos no campo publicados em inglês em revistas indexadas e revisadas por pares e combinamos a análise de gênero e os princípios da Linguística de Corpus para identificar as realizações das funções retóricas dos textos. Primeiramente, a estrutura retórica foi descrita. Em seguida, as foram identificadas, extraídas e analisadas. Resultados: Do total, 92% dos textos seguem um padrão, composto de cinco a nove seções. Oito nódulos colocacionais frequentes foram identificados (study, result, method, conclusion, review, analysis, patients e findings), em torno dos quais as Estruturas Lexicais se constroem. Conclusão: Embora tanto as palavras que remetem a conteúdo quanto as que se referem a funções das Estruturas Lexicais apresentem alguma variação, é possível perceber que as Estruturas Lexicais tipificam as realizações linguísticas das funções retóricas das seções correspondentes (background & objectives, methods, results e conclusion) e são adequadas para a observação de um padrão. Os dados obtidos foram usados para informar a criação de um quadro para a redação de resumos da especialidade.

REVISTA DE INVESTIGACIóN CLíNICA -CLINICAL AND TRANSLATIONAL INVESTIGATION-: EDITORS' CHOICES 6 YEARS LATER.

In this article, a series of original manuscripts and reviews published between 2015 and 2021 in the Revista de Investigación Clínica -Clinical and Translational Investigation- chosen by the Editors are presented. The articles were selected according to what the editors considered are the most outstanding contributions based on originality, and the potential impact of the information provided on translational medicine, rather than on the number of readings and citations.

A Crossover Randomized Trial of Visual Abstracts Versus Plain-Text Tweets for Disseminating Orthopedics Research.

BACKGROUND: Scientists, surgeons, and trainees are increasingly taking an active role on Twitter to find, disseminate, and exchange knowledge. The purpose of this study was to determine if peer-reviewed journal articles shared on Twitter using visual abstracts (VAs) improve user engagement compared with plain-text tweets. METHODS: A two-arm randomized controlled trial with crossover was performed. Manuscripts from the Journal of Arthroplasty were allocated to one of two arms and disseminated via the journal Twitter account (@JArthroplasty) as either a text-based tweet or a VA. The primary outcome was online engagement (a composite of retweets, replies, and likes) at 7 and 30 days after posting. Univariate analysis for nonparametric and parametric data was performed using Mann-Whitney test or Student t-tests, respectively; alpha was set at 0.05. RESULTS: 20 in-press manuscripts were randomized to standard tweets (10) or VAs (10) the same day of online publication. The mean number of engagements was higher in the VA group at seven (412 ± 216 vs 195 ± 133; P = .016) and 30 days (495 ± 204 vs 244 ± 162; P = .007). After the crossover, similar results were reported. Overall, VAs attracted a significantly greater number of engagements than standard tweets. Most engagement for both plain-text tweets and VAs occurred shortly after the tweet is posted. CONCLUSION: Online, public engagement with orthopedic research is generally low. However, when VAs are used to communicate research through social media outlets such as Twitter, the overall research engagement significantly increases compared with plain-text tweets.

Factors associated with the reporting quality of low back pain systematic review abstracts in physical therapy: a methodological study.

BACKGROUND: Abstracts of systematic reviews (SR) are frequently used to guide clinical decision-making. However, if the abstract is inadequately reported, key information may be missing and it may not accurately summarize the results of the review. OBJECTIVE: We aimed to investigate 1) if abstracts are fully reported; 2) if abstract reporting is associated with review/journal characteristics in physical therapy for low back pain (LBP); and 3) if these abstracts are consistent with the corresponding full texts. METHODS: We searched the Physiotherapy Evidence Database for SRs in physical therapy for LBP published between 2015 and 2017. Associations between abstract reporting quality and review/journal characteristics were explored with linear regression. Abstract reporting was assessed with the 12 item Preferred Reporting Items for Systematic Reviews and Meta-Analyses for abstracts (PRISMA-A) checklist. Consistency of reporting between abstracts and the full text was evaluated by comparing responses to each item of the PRISMA-A using Kappa coefficients. Methodological quality of the reviews was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR-2). RESULTS: We included 66 SRs, 9 Cochrane and 57 non-Cochrane. Review methodological quality ranged from 'high' (8%) to 'critically low' (76%). The mean ± SD of the "total number of PRISMA-A fully reported items" (range 0-12 points for fully reported items) was 4.1 ±â€¯1.9 points for non-Cochrane review abstracts and 9.9 ±â€¯1.1 points for Cochrane abstracts. Factors associated with reporting quality of abstracts were: journal impact factor (ß 0.20; 95% CI: 0.06, 0.35), number of words in abstract (ß 0.01; 95% CI: 0.00, 0.01) and review methodological quality ('critically low' with ß -3.06; 95% CI: -5.30, -0.82; with 'high' as reference variable). There was typically inconsistent reporting between abstract and full text, with most Kappa values lower than 0.60. CONCLUSIONS: The abstracts of SRs in physical therapy for LBP were poorly reported and inconsistent with the full text. The reporting quality of abstracts was higher in journals with a higher impact factor, in abstracts with a greater number of words, and when the review was of higher methodological quality.

Eight in Every 10 Abstracts of Low Back Pain Systematic Reviews Presented Spin and Inconsistencies With the Full Text: An Analysis of 66 Systematic Reviews.

STUDY DESIGN: Overview study. BACKGROUND: Abstracts of systematic reviews have presented 'spin' (i.e. overstated interpretation of study results) and inconsistency with the full text. OBJECTIVES: 1. Do abstracts of low back pain reviews contain spin? 2. Do these abstracts consistently represent the full text? 3. Is abstract spin associated with the type of conclusion? METHODS: We searched the Physiotherapy Evidence Database (PEDro) on 10th January 2018. Data were extracted from systematic reviews of physiotherapy interventions for low back pain, published between 2015 and 2017. Spin was assessed using a 7-item checklist. We evaluated consistency by comparing information contained in the abstract and the full text using the 7-item checklist with Kappa coefficient analysis. We used logistic regression analysis to evaluate the association between spin in the abstract and type of conclusion. We evaluated methodological quality using the AMSTAR-2 (A MeaSurement Tool to Assess systematic Reviews). RESULTS: We included 66 eligible systematic reviews, subdivided into Cochrane (n=9) and non-Cochrane (n=57) reviews. There was some form of spin in 80% of abstracts. Abstracts of non-Cochrane reviews were not consistent with the full text (fair to moderate agreement). Cochrane review abstracts had substantial to almost perfect agreement with the full text. Spin was not associated with the type of conclusion in all systematic reviews (P < 0.05). The methodological quality ranged from 'high' to 'critically low'. CONCLUSIONS: The abstracts of systematic reviews evaluating physiotherapy interventions for low back pain need improvement. J Orthop Sports Phys Ther, Epub 23 Aug 2019. doi:10.2519/jospt.2020.8962.

Detection of incident breast and colorectal cancer cases from an administrative healthcare database in Catalonia, Spain.

OBJECTIVE: To validate the Catalan minimum basic data set (MBDS) of hospital discharges as an information source for detecting incident breast (BC) and colorectal cancer (CRC), against the Hospital del Mar Cancer Registry (RTHMar) in Barcelona (Spain) as the gold standard. METHODS: Using ASEDAT software (Analysis, Selection and Extraction of Tumour Data), we identified Catalan public hospital discharge abstracts in patients with a first-time diagnosis of BC and CRC in the years 2005, 2008, and 2011, aggregated by unique patient identifiers and sorted by date. Once merged with the RTHMar database and anonymized, tumour-specific algorithms were validated to extract data on incident cases, tumour stage, surgical treatment, and date of incidence. RESULTS: MBDS had a respective sensitivity and positive predictive value (PPV) of 78.0% (564/723) and 90.5% (564/623) for BC case detection; and 83.9% (387/461) and 94.9% (387/408) for CRC case detection. The staging algorithms overestimated the proportion of local-stage cases and underestimated the regional-stage cases in both cancers. When loco-regional stage and surgery were combined, sensitivity and PPV reached 98.3% and 99.8%, respectively, for BC and 96.4% and 98.4% for CRC. The differences between dates of incidence between RTHMar and MBDS were greater for BC cases without initial surgery, whereas they were generally smaller and homogeneous for CRC cases. CONCLUSIONS: The MBDS is a valid and efficient instrument to improve the completeness of a hospital-based cancer registry (HBCR), particularly in BC and CRC, which require hospitalization and are predominantly surgical.

Analysis of urinary VOCs using mass spectrometric methods to diagnose cancer: A review.

The development of non-invasive screening techniques for early cancer detection is one of the greatest scientific challenges of the 21st century. One promising emerging method is the analysis of volatile organic compounds (VOCs). VOCs are low molecular weight substances generated as final products of cellular metabolism and emitted through a variety of biological matrices, such as breath, blood, saliva and urine. Urine stands out for its non-invasive nature, availability in large volumes, and the high concentration of VOCs in the kidneys. This review provides an overview of the available data on urinary VOCs that have been investigated in cancer-focused clinical studies using mass spectrometric (MS) techniques. A literature search was conducted in ScienceDirect, Pubmed and Web of Science, using the keywords "Urinary VOCs", "VOCs biomarkers" and "Volatile cancer biomarkers" in combination with the term "Mass spectrometry". Only studies in English published between January 2011 and May 2020 were selected. The three most evaluated types of cancers in the reviewed studies were lung, breast and prostate, and the most frequently identified urinary VOC biomarkers were hexanal, dimethyl disulfide and phenol; with the latter seeming to be closely related to breast cancer. Additionally, the challenges of analyzing urinary VOCs using MS-based techniques and translation to clinical utility are discussed. The outcome of this review may provide valuable information to future studies regarding cancer urinary VOCs.

Lo mejor del Congreso 2019 del American College of Cardiology / The best of the 2019 American College of Cardiology Congress / O melhor do Congresso do Colégio Americano de Cardiologia 2019

Resumen: Como todos los años, en esta oportunidad se celebró el 68º Congreso del Colegio Americano de Cardiología (ACC, por su sigla en inglés) entre los días 16 y 18 de marzo en Nueva Orleans, Luisiana. Ambientado en la ciudad del Mardi Gras y el jazz, nuevamente convocó a la cardiología mundial para promover el conocimiento a través de la presentación de múltiples actividades científicas. Contó con la presencia de más de 16.000 asistentes y se recibieron 2.300 artículos, muchos de los cuales, sin duda, modificarán la práctica clínica actual. Cabe destacar, asimismo, la presentación de la Guía de Prevención Primaria de la Enfermedad Cardiovascular, donde resalta el casi total abandono del ácido acetilsalicílico en prevención primaria debido a la falta de beneficio neto. Realizaremos un breve resumen de algunos de los principales trabajos científicos presentados: - Antithrombotic Therapy after Acute Coronary Syndrome or PCI in Atrial Fibrillation - The AUGUSTUS Trial - Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients - The PARTNER 3 trial - The Safety and Efficacy of Femoral Access in STEMI: The SAFARI-STEMI Trial - One-Month Dual Antiplatelet Therapy Followed by Clopidogrel Monotherapy versus Standard 12-Month Dual Antiplatelet Therapy With Clopidogrel After Drug-Eluting Stent Implantation. STOP-DAPT 2 Trial - Results of a Large-scale, App-based Study to Identify Atrial Fibrillation Using a Smartwatch: The Apple Heart Study

Summary: As every year, on this occasion the 68th Congress of the American College of Cardiology was held from March 16 to 18 in New Orleans, Louisiana. Set in the city of Mardi Gras and jazz, it once again called on global cardiology to promote knowledge through the presentation of multiple scientific activities. It counted with the presence of more than 16.000 attendees and 2.300 articles were received, many of which will undoubtedly modify the current clinical practice. It is also worth mentioning the presentation of the Primary Prevention of Cardiovascular Disease Guideline, which highlights the almost total discontinuation of acetylsalicylic acid in primary prevention due to the lack of net benefit. We will make a brief summary of some of the main scientific papers presented: - Antithrombotic Therapy after Acute Coronary Syndrome or PCI in Atrial Fibrillation - The AUGUSTUS Trial - Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients - The PARTNER 3 trial - The Safety and Efficacy of Femoral Access in STEMI: The SAFARI-STEMI Trial - One-Month Dual Antiplatelet Therapy Followed by Clopidogrel Monotherapy versus Standard 12-Month Dual Antiplatelet Therapy With Clopidogrel After Drug-Eluting Stent Implantation.

Reporting Quality of Randomized Controlled Trials of Periodontal Diseases in Journal Abstracts-A Cross-sectional Survey and Bibliometric Analysis.

OBJECTIVE: Randomized controlled trials (RCTs) by proper design, conduct, analysis, and reporting provide reliable information in clinical care. Reporting of RCT abstracts is of equal importance as there is evidence that many clinicians will change their clinical decisions based on RCT abstracts. The reporting quality of RCT abstracts has been suboptimal. It is not clear whether the reporting quality is related to the journal metrics. The main objective of this study is to conduct a cross-sectional survey to evaluate the reporting quality of RCTs of periodontal diseases in journal abstracts and to perform a bibliometric analysis. The null hypothesis was that there is no association between the journal metrics (5-year impact factor, Eigenfactor score, and Article Influence Score), abstract metrics (word count, and number of authors), journal endorsement of Consolidated Standards of Reporting Trials (CONSORT), and the overall quality of reporting of CONSORT RCT abstract-modified checklist questions. MATERIALS: CONSORT RCT abstract extension checklist with explanation and elaboration was used and modified to assess the quality of reporting of RCT abstracts of periodontal diseases in the journal abstracts in the year 2012. Bibliometric analysis of journal metrics (5-year impact factor, Eigenfactor score, and Article Influence Score) and abstract metrics (number of authors and abstract word count), the geographic distribution, and the CONSORT-endorsing journal abstracts was compared with the reporting quality of RCT abstracts in periodontal diseases. Calibration and intrarater agreement were done before the data collection and analysis. A second reviewer was consulted for independent evaluation and clarification as needed. For descriptive analysis, the values of continuous variables were expressed as median and interquartile ranges (IQRs) and as proportion percent for binary categorical variables. For association analysis between the binary (yes/no) response variable and the continuous variable, the Mann-Whitney test (for independent samples) was used. For examining the association between 2 categorical variables, Fisher's exact test was used. The chi-square test was performed to examine the association between 2 sets of binary response variables (yes/no). A P value of < .05 was considered statistically significant. All analyses were conducted using SAS, version 9.4. RESULTS: A total of 198 RCT abstracts of periodontal diseases in the year 2012 from 57 journals were included in the study. Fifteen journals, listed as endorsers of CONSORT, contributed 108 RCT abstracts. Four journals (Journal of Periodontology, Journal of Clinical Periodontology, Clinical Oral Implants Research, and European Journal of Oral Implantology) contributed 84 of 198 RCT abstracts in 2012. European countries contributed the majority (n = 81, 40.91%) of RCT abstracts. Among 31 countries in this study, United States contributed the most RCTs (n = 28, 14.14%) followed by India (24, 12.12%), Italy (n = 22, 11.11%), and Brazil (n = 20, 10.1%). The frequency of journal metrics were 5-year impact factor (median 2.316; IQR: 1.439-2.970); Eigenfactor score (0.00474; 0.00202-0.01395); and Article Influence Score (0.553; 0.382-0.755). The number of authors in 198 RCT abstracts ranged between 2 and 20 (median n = 5, IQR: 4-6), whereas the word count ranged between 48 and 569 (median 235, IQR: 205-269). All RCT abstracts reported the experimental interventions (checklist question #5, frequency 100%). Some items were almost always reported-participant eligibility criteria (#3, 99%); comparison interventions (#6, 99.5%); specific objective or hypothesis (#7, 99.5%); primary outcome (#8, 99.5%); and reporting trial results as a summary (#16, 98.5%). All RCT abstracts never reported how the allocations were concealed (#11, 0) and the source of funding for the trials (#23, 0). Some items were almost always never reported-the number of participants included in the analysis for each intervention (#15, 2%); trial registration number (#21, 2.5%); name of trial register (#22, 2.5%); and how the randomization or sequence generation was done (#22). Dismal reporting was noted in many checklist questions including the identification of the study as randomized in the title #1, 51%; design of the trial #2, 32.8%; trial setting #4, 3.5%; randomization #10, 3.5%; blinding #12, 21.7%; details about blinding #13, 8.1%; number of participants randomized to each intervention #14, 26.3%; effect size #17, 13.6%; precision of the estimate of the effect #18, 6.1%; and adverse effects #19, 14.1%. Strikingly, there was a very high reporting of statistical significance #25, 92.4%. European countries, in particular, reported relatively better than other countries in essential questions such as #17 effect size reporting, and #18 precision (uncertainty), which have been largely unreported by rest of the countries. Finally, despite the majority of RCTs published in 2012 were by CONSORT-endorsing journals, there was no difference in the quality of reporting in majority of checklist items when compared with journals not listed as CONSORT endorsers. With few exceptions, there was no statistically significant association between the majority of the CONSORT RCT abstract checklist questions and the journal metrics and abstract metrics analyzed in this study. Unexpectedly, lower ranking journals in journal metrics reported certain essential checklist questions relatively better. CONCLUSION: The reporting quality of RCT of periodontal diseases in the journal abstracts published in 2012 needs substantial improvement. These items have been laid out in this study to help all stakeholders-authors, clinicians, researchers, peer reviewers, journal editors, and publishers to take note and help with the improvement of the same. Despite few significant associations in the bibliometric factors analyzed with better reporting, the results overall led to the failure to reject the null hypothesis that there is no association between the journal metrics, word count, and number of authors and the quality of reporting of CONSORT RCT abstract-modified checklist questions.

Conversion of Plastic Surgery meeting abstract presentations to full manuscripts: a brazilian perspective / Conversão dos resumos apresentados em congressos de Cirurgia Plástica em manuscritos completos: uma perspectiva brasileira

ABSTRACT Objective: to assess the conversion rate of Plastic Surgery meeting abstract presentations to full manuscript publications and examine factors associated with this conversion. Methods: we assessed the abstracts presented at the 47th and 48th Brazilian Congresses of Plastic Surgery by cross-referencing with multiple databases. We analyzed the Abstracts' characteristics associated with full manuscript publications. Results: of the 200 abstracts presented, 50 abstracts were subsequently published in full, giving the conference a conversion rate of 25%. The mean time to publish was 15.00±13.75 months. In total, there were 4.93±1.63 authors per abstract and 67.8±163 subjects per abstract; 43.5% of the abstracts were of retrospective studies; 69% comprised the plastic surgery topics head and neck, and chest and trunk, and 88.5% had no statistical analysis. Overall, 80% of the manuscripts were published in plastic surgery journals, 76% had no impact factor and 52% had no citations. Bivariate and multivariate analyses revealed the presence of statistical analysis to be the most significant (p<0.05) predictive factor of conversion of abstracts into full manuscripts. Conclusion: the conversion rate found from this bibliometric research appeared a bit lower than the conversion trend of international plastic surgery meetings, and statistical analysis was a determinant of conversion success.

RESUMO Objetivo: avaliar a taxa de conversão de resumos apresentados em congressos de Cirurgia Plástica em publicações de manuscritos completos e examinar fatores associados a essa conversão. Métodos: resumos apresentados nos XLVII e XLVIII Congressos Brasileiros de Cirurgia Plástica foram avaliados por meio de referências cruzadas em diversos bancos de dados. Averiguaram-se as características dos resumos associadas às publicações de manuscritos completos. Resultados: dos 200 resumos apresentados, 50 foram posteriormente publicados na íntegra, determinando uma taxa de publicação de 25%. O tempo médio para publicação foi 15,00±13,75 meses. No total, houve 4,93±1,63 autores/resumo e 67,8±163 pacientes/resumo; 43,5% dos resumos foram estudos retrospectivos; 69% pertenciam aos tópicos crânio, cabeça e pescoço, e tórax e tronco e 88,5% não apresentavam análise estatística. No geral, 80% dos manuscritos foram publicados em revistas de Cirurgia Plástica, 76% não exibiam fator de impacto e 52% não possuíam citações. As análises bivariada e multivariada revelaram que a presença de análise estatística foi o fator preditivo significativo (p<0,05) para a conversão de resumos em manuscritos completos. Conclusão: a taxa de conversão deste estudo bibliométrico foi inferior à tendência de conversão descrita em congressos internacionais de Cirurgia Plástica, e a presença de análise estatística foi um determinante para o sucesso de conversão.

Publication rate of abstracts presented in a Brazilian experimental surgery congress

ABSTRACT PURPOSE: To verify the publication rate of the abstracts presented at the XII Brazilian Congress of Experimental Surgery. METHODS: We performed a cross-sectional study that evaluated if the abstracts accepted for presentation at the XII Brazilian Congress of Experimental Surgery were published in periodics. The information was acquired using the Scielo, Medline / Pubmed, LILACS and Google Scholar databases. RESULTS: From all the abstracts presented, only 77 (40.52%) were published in scientific journals. Of this total, 14 (18.18%) were published prior to the conference 35 (45.45%) in the same year that occurred congress, 56 (72.72%) in the period 2011-2013 and 63 (81, 81%) between the Congress and the year 2015. Regarding the geographical distribution of summaries, 42 (22%) were from the northern region, 19 (10%) from the Northeast, 8 (4%) Midwest, 116 (61%) from the Southeast and 5 (3%) from the south. CONCLUSION: The publication rate of the abstracts presented at the XII Brazilian Congress of Experimental Surgery was 40,52%, most from the state of Sao Paulo.

Discrepancies Between Plastic Surgery Meeting Abstracts and Subsequent Full-Length Manuscript Publications.

BACKGROUND: The purpose of this bibliometric study was to assess the discrepancies between plastic surgery meeting abstracts and subsequent full-length manuscript publications. METHODS: Abstracts presented at the Brazilian Congress of Plastic Surgery from 2010 to 2011 were compared with matching manuscript publications. Discrepancies between the abstract and the subsequent manuscript were categorized as major (changes in the purpose, methods, study design, sample size, statistical analysis, results, and conclusions) and minor (changes in the title and authorship) variations. RESULTS: The overall discrepancy rate was 96 %, with at least one major (76 %) and/or minor (96 %) variation. There were inconsistencies between the study title (56 %), authorship (92 %), purpose (6 %), methods (20 %), study design (36 %), sample size (51.2 %), statistical analysis (14 %), results (20 %), and conclusions (8 %) of manuscripts compared with their corresponding meeting abstracts. CONCLUSION: As changes occur before manuscript publication of plastic surgery meeting abstracts, caution should be exercised in referencing abstracts or altering surgical practices based on abstracts' content. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Publications generated from abstracts presented at the 28thCongresso Brasileiro de Patologia and the 28th Congreso de la Sociedad Latinoamericana de Patologia, in 2011 / Publicações geradas a partir de resumos apresentados no XXVIII Congresso Brasileiro de Patologia e no XXVIII Congreso de la Sociedad Latinoamericana de Patología, realizados em 2011

ABSTRACTIntroduction:The medical congresses are an efficient way, although restricted, to expose the scientific production of a particular specialty. However, the number of complete articles published resulting from papers presented at congresses and published as abstracts is much lower than the number of papers presented during the meetings.Objective:Scale the number of complete articles published and indexed in online databases, from 2012 to January 2015, originally presented at the 28th Congresso Brasileiro de Patologia (28th Brazilian Congress of Pathology) and the 28th Congreso de la Sociedad Latinoamericana de Patología (28th Latin American Society of Pathology Congress).Material and method:In the meetings mentioned 701 papers were presented and their abstracts published in the congresses annals. An observational retrospective study was conducted consulting the following biomedical databases: Scientific Electronic Library Online (Scielo) and US National Library of Medicine on the National Institutes of Health (PubMed), with the help of the Google search engine, based on the article title and the list of authors.Results:From 701 studies analyzed, 635 (90.6%) were from Brazilian institutions, 60 (8.6%) from foreign institutions, and six (0.8%) did not identified their home institutions. There were found 63 (8.8%) complete articles published and indexed to consulted databases. International journals were the destination of 38 (60.3%) publications.Conclusion:The number of complete articles published in Pathology area arising from the papers presented in the studied meetings in the first three years after the meetings is relatively small. This number is low compared with other international conferences; however, it is higher than some Brazilian medical congresses analyzed in similar studies.

RESUMOIntrodução:Os congressos médicos são um meio eficiente, embora restrito, de expor a produção científica de uma determinada especialidade. Entretanto, o número de artigos completos publicados resultantes dos trabalhos apresentados em congressos e publicados como resumos é muito inferior ao número dos trabalhos apresentados durante os eventos.Objetivo:Dimensionar o número de artigos completos publicados e indexados em bases de dados virtuais, no período de 2012 a janeiro de 2015, apresentados originalmente no XXVIII Congresso Brasileiro de Patologia e no XXVIII Congreso de La Sociedade Latinoamericana de Patología.Material e método:Nos eventos mencionados, foram apresentados 701 trabalhos e seus resumos publicados nos anais do congresso. Efetuou-se um estudo retrospectivo observacional consultando as seguintes bases de dados biomédicas: Scientific Electronic Library Online (Scielo) e US National Library of Medicine do National Institutes of Health (PubMed), com o auxílio do buscador Google, tomando por base o título do trabalho e a lista de autores.Resultados:Dos 701 trabalhos analisados, 635 (90,6%) eram originados de instituições brasileiras, 60 (8,6%), de instituições estrangeiras e em seis (0,8%) não foram identificadas as instituições de origem. Foram encontrados 63 (8,8%) trabalhos completos publicados e indexados às bases de dados consultadas. As revistas internacionais foram o destino de 38 (60,3%) publicações.Conclusão:É relativamente pequeno o número de artigos completos publicados na área de Patologia, resultantes dos trabalhos apresentados nos eventos estudados, nos três primeiros anos após a realização do evento. Esse número é baixo, quando comparado com o de outros congressos internacionais, contudo, é superior ao de alguns congressos médicos brasileiros analisados em estudos semelhantes.
