Estimating the prevalence of text overlap in biomedical conference abstracts.

ABSTRACT:

Background

Scientists communicate progress and exchange information via publication and presentation at scientific meetings. We previously showed that text similarity analysis applied to Medline can identify and quantify plagiarism and duplicate publications in peer-reviewed biomedical journals. In the present study, we applied the same analysis to a large sample of conference abstracts.

Methods

We downloaded 144,149 abstracts from 207 national and international meetings of 63 biomedical conferences. Pairwise comparisons were made using eTBLAST: a text similarity engine. A domain expert then reviewed random samples of highly similar abstracts (1500 total) to estimate the extent of text overlap and possible plagiarism.

Results

Our main findings indicate that the vast majority of textual overlap occurred within the same meeting (2%) and between meetings of the same conference (3%), both of which were significantly higher than instances of plagiarism, which occurred in less than .5% of abstracts.

Conclusions

This analysis indicates that textual overlap in abstracts of papers presented at scientific meetings is one-tenth that of peer-reviewed publications, yet the plagiarism rate is approximately the same as previously measured in peer-reviewed publications. This latter finding underscores a need for monitoring scientific meeting submissions - as is now done when submitting manuscripts to peer-reviewed journals - to improve the integrity of scientific communications.

Project description:The language encompassing health conditions can also influence behaviors that affect health outcomes. Few published quantitative studies have been conducted that evaluate HIV-related terminology changes over time. To expand this research, this study included an analysis of a dataset of abstracts presented at the International AIDS Conference (IAC) from 1989 to 2014. These abstracts reflect the global response to HIV over 25 years. Two powerful methodologies were used to evaluate the dataset: text mining to convert the unstructured information into structured data for analysis and data visualization to represent the data visually to assess trends.The purpose of this project was to evaluate the evolving use of HIV-related language in abstracts presented at the IAC from 1989 to 2014.Over 80,000 abstracts were obtained from the International AIDS Society and imported into a Microsoft SQL Server database for data processing and text mining analyses. A text mining module within the KNIME Analytics Platform, an open source software, was then used to mine the partially processed data to create a terminology corpus of key HIV terms. Subject matter experts grouped the terms into categories. Tableau, a data visualization software, was used to visualize the frequency metrics associated with the terms as line graphs and word clouds. The visualized dashboards were reviewed to discern changes in terminology use across IAC years.The major findings identify trends in HIV-related terminology over 25 years. The term "AIDS epidemic" was dominantly used from 1989 to 1991 and then declined in use. In contrast, use of the term "HIV epidemic" increased through 2014. Beginning in the mid-1990s, the term "treatment experienced" appeared with increasing frequency in the abstracts. Use of terms identifying individuals as "carriers or victims" of HIV rarely appeared after 2008. Use of the terms "HIV positive" and "HIV infected" peaked in the early-1990s and then declined in use. The terms "men who have sex with men" and "MSM" were rarely used until 1994; subsequently, use of these terms increased through 2014. The term "sex worker" steadily increased in frequency throughout conference years, whereas the term "prostitute" decreased over time.The results of this study highlight changes in HIV terminology use over 25 years, including the addition, disappearance, and changing use of terms that reflect advances in HIV research and medical practice and destigmatization of the disease. Coupled with findings from related quantitative research, HIV-related terminology recommendations based on results of this study are included. Adoption of these recommendations will further efforts to use less stigmatizing language and facilitate effective communication between health professionals and people affected by HIV.

Project description:BACKGROUND: Current resuscitation guidelines recommend 3:1 Compression:Ventilation (C:V) ratio, however the most effective C:V ratio in newborns remains controversial. We recently demonstrate that if chest compressions (CC) are superimposed by sustained inflations (SI) return of spontaneous circulation (ROSC) and mortality are improved in asphyxiated newborn piglets when compared to standard coordinated 3:1 resuscitation. However, this has not been studied in newborns. OBJECTIVES: To determine if CC superimposed with SI impacts ROSC in infants <33 weeks with bradycardia or asystole compared to coordinated 3:1 C:V resuscitation. DESIGN/METHODS: In a pilot study, infants born <33 weeks gestational age with an heart rate <60/min or asystole were randomized to receive either “3:1 C:V” or “SS+CC”. Infants randomized to 3:1 received coordinated CC and ventilation according to the current resuscitation guidelines. Infants randomized to “SI+CC” received uninterrupted CC at a rate of 90/min superimposed by a SI of 30 sec. The default settings for airway pressures were peak inflation pressure of 24 cm H2O and a positive end expiratory pressure of 6 cm H2O. The primary outcome was duration of CC to achieve ROSC. Deferral of consent was approved by the institutional ethics committee. The trial was registered at ClinicalTrials.gov: NCT02083705. RESULTS: Five infants were randomized to each group; the mean (range) gestational age was 25 (24–27) weeks vs. 26 (23–28) weeks in the in the SI+CC and 3:1 group (P=0.433), respectively. Mean (SD) birth weight in the SI+CC group was 797 (208) g vs. 808 (182) g in the 3:1 group, (P=0.465) respectively. Mean (SD) ROSC was significantly decreased in the SI+CC group with 31 (8) sec vs. 138 (72) sec in the 3:1 group (P=0.011). One infant in each group died and only one infant in the 3:1 group received epinephrine. One infant in the SI+CC group and three in the 3:1 had intracranial hemorrhage grade 3 or greater. Three infants in the SI+CC group had necrotizing enterocolitis vs. one infant in the 3:1 group (P=0.197). CONCLUSION: Preterm infants <33 weeks had significant shorter ROSC when CC were superimposed by SI compared to using 3:1.
