What makes a good scientific presentation on artificial intelligence in medical imaging?

PURPOSE: Adequate communication of scientific findings is crucial to enhance knowledge transfer. This study aimed to determine the key features of a good scientific oral presentation on artificial intelligence (AI) in medical imaging. METHODS: A total of 26 oral presentations dealing with original research on AI studies in medical imaging at the 2023 RSNA annual meeting were included and systematically assessed by three observers. The presentation quality of the research question, inclusion criteria, reference standard, method, results, clinical impact, presentation clarity, presenter engagement, and the presentation's quality of knowledge transfer were assessed using five-point Likert scales. The number of slides, the average number of words per slide, the number of interactive slides, the number of figures, and the number of tables were also determined for each presentation. Mixed-effects ordinal regression was used to assess the association between the above-mentioned variables and the quality of knowledge transfer of the presentation. RESULTS: A significant positive association was found between the quality of the presentation of the research question and the presentation's quality of knowledge transfer (odds ratio [OR]: 2.5, P = 0.005). The average number of words per slide was significantly negatively associated with the presentation's quality of knowledge transfer (OR: 0.9, P < 0.001). No other significant associations were found. CONCLUSION: Researchers who orally present their scientific findings in the field of AI and medical imaging should pay attention to clearly communicating their research question and minimizing the number of words per slide to maximize the value of their presentation.

The crisis of medical congresses and the future ahead.

The landscape of medical congresses is currently facing a crisis due to various factors. The COVID-19 pandemic has led to the cancellation or transition of many in-person events to virtual formats, impacting the benefits of face-to-face interactions and networking opportunities. Declining attendance, concerns about the quality of content, and ethical issues related to the pharmaceutical industry's influence have further contributed to this crisis. To address these challenges, potential solutions have been identified. Combining in-person and virtual components, hybrid events are gaining popularity and offer increased flexibility and accessibility. Reducing costs and expanding access can be achieved through tiered registration fees based on income or professional status, utilising lower-cost venues, collaborating with sponsors, and leveraging technology for administrative processes. Improving content quality and transparency involves rigorous peer review processes and clear guidelines for disclosing conflicts of interest. The future of medical congresses will be shaped by trends such as the increasing use of digital technology, interdisciplinary collaboration, and patient-centred care. Virtual platforms and immersive technologies will enhance educational content and networking experiences. Addressing ethical concerns requires stricter guidelines for sponsorship, transparency, and evidence-based content. Broader societal issues, such as health equity and climate change, must be incorporated into congress agendas. In conclusion, the crisis involving medical congresses presents challenges and opportunities for transformation. By embracing innovative solutions, adapting to changing needs, and addressing ethical and societal concerns, medical congresses can continue to play a crucial role in advancing healthcare and improving patient outcomes.

Assessing the level of evidence of presented studies at the Brazilian Congress of Coloproctology

Introduction: Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods: A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results: A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions: Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

We gathered the data through observation in academic contexts and based on elements of anonymous satisfaction surveys, with prior informed consent of participants. Results: fourteen students participated, six in 2021 and eight in 2022. All were women and medical students (50% fourth year, 35% sixth year, and 15% fifth year). The techniques implemented favored participation and promoted active, project-based learning. They mentioned positive aspects such as the practical academic approach, the availability of the teaching team for any doubts, the time and enthusiasm for teaching, and encouraging participation. The theory videos were a valuable review tool, and team meetings received high praise even if the one-on-one meetings received much attention as help and support before the scientific congresses. In general, they stated that it was an enriching experience that showed that you can achieve what you thought impossible. All of them actively participated in at least one scientific congress, and 50% were co-authors of an academic publication. Conclusion: the students assumed commitments and responsibilities and incorporated competencies and skills in project implementation and dissemination. This educational experience helped to optimize class time for exchange, discussion, and doubts. The resources produced, the activities developed, and the contents addressed are now available at the institutional level. (AU)

[History of congresses of surgeons in Russia (1900-2022)]. / Istoriya s"ezdov khirurgov Rossii (1900­2022).

The authors describe a history of surgical congresses in the Russian Empire, the USSR and the Russian Federation from the I Congress of Russian Surgeons held on December 28-30, 1900 in Moscow in the building of the Moscow Meeting of Doctors to the XLVIII (XIV) Congress of Surgeons of Russia held on November 25-27, 2022 in Moscow in the hotel «Cosmos¼. The time and place of congresses, as well as chairmen are named. The main issues are listed. Scientific issues of congresses between 1900 and 1986 are summarized in tables. The authors present a brief history of Russian surgical societies including the current Russian Society of Surgeons. Surgical forums of the 21st century are considered in detail (Congresses of Surgeons of Russia, National Surgical Congresses, All-Russian Surgical Forums). Finally, the authors came to conclusion that 55 surgical forums have been held in Russia for more than 120 years. Surgeons presented all aspects of surgery in Russia. Their issues are essentially the history of Russian surgery, and their works are sources for analysis of the past and present of Russian surgery.

Primum Non Discernere: Glass Ceilings and Female Representation at the European Association of Urology and European Society for Paediatric Urology Annual Meetings, 2012-2022.

Background: The term glass ceiling coined by Loden in 1978 is commonly used to describe difficulties faced by minorities and women when trying to move into senior roles. Objective: To analyse trends and patterns for female representation at the European Association of Urology (EAU) and European Society for Paediatric Urology (ESPU) annual general meetings over the past decade. Design setting and participants: We used objective data on female representation in the roles of chairs, moderators, and lecture speakers at the EAU and ESPU meetings from 2012 to 2022. Outcome measurements and statistical analysis: We evaluated gender based representation in paediatric urology sessions at the EAU and ESPU meetings, collecting data on the overall number of sessions, lectures, symposiums, abstract/poster sessions, and courses, and analysed the male/female ratio. Data were derived from printed and digital programmes for the relevant meetings. Results and limitations: During the period from 2012 to 2022, the percentage female representation varied from 0% (2012) to a maximum of 35% (2022) at EUA paediatric urology sessions, and from 13.5% (2014) to a maximum of 32% (2022) at ESPU meetings. Both associations show clear progression towards equality. Conclusions: Female representation at EAU and ESPU meetings has risen over the years, reaching 35% and 32%, respectively, in 2022, which is in line with the number of female members. We hope that this motivates a move towards the equality objectives for 2030. A clear and fundamental societal change is needed, with fair and more consistent institutional policies and framework commitments in the areas of science, medicine, and global health. Gender equality and diversity taskforces are essential to achieve these goals. Patient summary: We analysed the male/female ratio for participants in annual meetings held by the European Association of Urology and the European Society for Paediatric Urology. From a low level in 2012, the ratio increased to over 30% in 2022, in line with the female membership of the societies. Focus on fair and consistent policies is needed to ensure that women are well represented in medicine.

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.

Reporting inconsistency between published conference abstracts and article abstracts of randomised controlled trials in prosthodontics presented at IADR general sessions.

Background: There is commonly a discrepancy between conference abstracts and published article abstracts in prosthodontic randomized controlled trials (RCTs), which may mislead the scholars those attend conferences. Objective: To identify the characteristics predicting inconsistency between conference abstracts and published article abstracts in prosthodontic RCTs. Methods: The conference abstracts of prosthodontic RCTs presented at the IADR general sessions from 2002 to 2015 were searched. Electronic searches of MEDLINE, EMBASE, the Cochrane Library, and Google Scholar databases were conducted to match full-text publications for conference abstracts. Two investigators extracted basic characteristics and assessed the consistency and reporting quality independently and in duplicate. The linear regression model was used to analyze the predictors of inconsistency. Results: A total of 147 conference abstracts were matched with published articles. Results for the secondary outcome measure, Statistical analysis, and precision measure were less than 50% consistent, and even nearly 5% of the studies had opposite conclusions. Multiple linear regression analysis showed that three factors were correlated with lower inconsistency, including continent of origin (p = 0.011), presentation type (p = 0.017), and difference in reporting quality (p = 0.013). Conclusion: Conference attendees should cautiously treat the findings of the conference abstracts. Researchers should improve the precision of the information delivered at conferences. We recommend the authors of RCTs to explain the primary difference between conference abstracts and article abstracts.

Publication rates of congress abstracts is associated with abstract quality: Evaluation of Turkish National Medical Education Congresses and Symposia between 2010 and 2014 using MERSQI.

There are many parameters that could be used to evaluate the quality of scientific meetings such as publication rates of meeting abstracts as full-text articles after the meeting or scoring with validated quality scales/tools that evaluate individual papers, project proposals, or submitted abstracts. This study aimed to determine the full-text publication rates for abstracts presented at Turkish National Medical Education Congresses and Symposia and to assess the quality of given abstracts. Abstracts presented at national medical education congresses and symposia between 2010 and 2014 in Türkiye were evaluated. Initially, the abstracts were evaluated if they were published as full-text articles in international and national peer-reviewed journals following the meeting. Secondly, the quality of presented abstracts was assessed with the Medical Education Research Study Quality Instrument (MERSQI) scale. Overall publication rate for the abstracts was 11.3%. The publication rate of oral and poster presentations were 26.6% and 8.1%, respectively. Oral presentations had a statistically higher publication rate than poster presentations (p = .000). The mean MERSQI score for abstracts was 7.73 ± 2.59. The oral presentations had higher MERSQI mean scores than poster presentations (8.28 ± 2.46 vs. 7.61 ± 2.6; p = .032). Similarly, published abstracts had a significantly higher score compared to unpublished abstracts (10.07 ± 2.74 vs. 7.43 ± 2.41; p = .000). Interestingly, there was no statistical difference between the mean MERSQI scores of the published oral and poster presentations (9.33 ± 2.45 vs. 10.61 ± 2.72; p = .101). This study showed that the main factor for a meeting abstract to be published as a full-text article is the scientific quality of the study. The quality of presentations at annual medical education meetings in Türkiye were low compared with international meetings which did not improve over five years. An institutional policy that would set quality standards for medical education research and increase the awareness of researchers on the topic might help improve the design, execution, and reporting of such studies in Türkiye. The MERSQI could be a valuable tool to monitor the quality of submitted abstracts and to increase the awareness of novice researchers on high quality research.

Confiabilidad de una escala de valoración de resúmenes para congresos

Introducción: En 2013, desarrollamos una escala, para evaluar resúmenes de congresos de la Sociedad de Cirujanos de Chile (SOCICH). Objetivo: Determinar consistencia interna y confiabilidad interobservador de una escala para evaluar resúmenes de congresos. Material y Método: Estudio de confiabilidad. Doce cirujanos fueron capacitados de forma virtual durante 8 horas, para aplicar la escala. Una vez finalizado el entrenamiento, se les envió un cuestionario para evaluar contenidos de la capacitación, y varios resúmenescasos para ser evaluados con la escala antes señalada. Se aplicó estadística descriptiva, luego se estimó el grado de acuerdo entre observadores para cada ítem de la escala. Posteriormente, se evaluó el coeficiente de correlación (CCI), utilizando un modelo de dos factores mixtos en el que los efectos de los evaluadores son aleatorios y los ítems fijos; utilizando una definición de acuerdo absoluto. Además, se evaluó la consistencia interna de los ítems utilizando alfa de Cronbach, considerando intérvalos de confianza del 95% (IC 95%). Resultados: Luego de analizar las mediciones de los 9 ítems por los 12 observadores, se verificó que el CCI fue de 0,871; con un IC 95% de 0,700; 0,965. El valor de la consistencia interna fue de 0,7 considerando los 9 ítems, no se recomienda eliminar ningún ítem. Conclusión: La escala tiene buena confiabilidad interobservador y los ítems son consistentes entre sí; por lo que puede ser considerada como un instrumento confiable para la valoración de resúmenes de congresos.

Background: In 2013, we developed a scale to evaluate the abstracts of the congresses of the Society of Surgeons of Chile (SOCICH). Objective: To determine internal consistency and interobserver reliability of a scale to evaluate conference abstracts. Material and Methods: Reliability study. Twelve surgeons were trained virtually for 8 hours, to apply the scale. Once the training was finished, they were sent a questionnaire to evaluate the contents of the training, and several summaries-cases to be evaluated with the aforementioned scale. Descriptive statistics were applied, then the degree of agreement between observers was estimated for each item of the scale. Subsequently, intraclass correlation coefficient (ICC) was evaluated, using a mixed two-factor model where the effects of the evaluators are random and the items are fixed, using a definition of absolute agreement. In addition, the internal consistency of the items was evaluated using Cronbach's alpha, considering 95% confidence intervals (95% CI). Results: After analyzing the measurements of the 9 items by the 12 observers, it was verified that the ICC was 0.871; with a 95% CI of 0.700; 0.965. The internal consistency value was 0.7 considering the 9 items, it is not recommended to delete any item. Conclusions: The scale has good internal consistency and interobserver reliability. Therefore, it can be considered as reliable instrument to be used in the evaluation of abstracts for congresses.

Presencia de las distintas áreas quirúrgicas en el Congreso Nacional de Cirugía. Análisis de los últimos 12 años

Introducción: Los trabajos científicos permiten divulgar, compartir y contrastar resultados a terceros. Una de las formas de ver la actividad investigativa de cada especialidad es a través de las presentaciones que realizan en reuniones científicas. Objetivo: Describir el número de presentaciones de las distintas especialidades o áreas quirúrgicas en Chile en el principal congreso realizado a nivel nacional y evaluar si el comportamiento fue distinto durante los años de pandemia por coronavirus. Material y Método: Estudio bibliométrico del Congreso Chileno de Cirugía entre los años 2010 y 2021 evaluando el número total de presentaciones por área quirúrgica, año de presentación y período categorizado en 2010 a 2019 y 2020 a 2021. Se realiza estadística descriptiva y análisis de asociación de medias de publicaciones por área y período. Resultados: Se identificaron 4.462 presentaciones, incluyendo resúmenes orales, póster, videos y jornada de residentes. La media total fue 371,8 trabajos anuales. Coloproctología y Cirugía Gastroesofágica aportaron un total de 616 (13,8%) y 598 (13,4%) respectivamente. La media de presentaciones anuales previo a la pandemia por coronavirus fue de 414, en contraste a los 160 trabajos anuales durante ella, existiendo una disminución significativa de medias de presentaciones por área de 27,6 (± 18,8) a 10,7 (± 8,69) (p < 0,001), sin diferencias sus porcentajes de participación respecto del total (p = 0,776). Conclusión: Coloproctología y Cirugía Gastroesofágica son las áreas quirúrgicas más representadas. Si bien en el período contemporáneo a la pandemia por coronavirus significó una disminución en las presentaciones, no se observó una modificación en el porcentaje de participación de algún área en particular.

Introduction: Scientific studies allow the disclosure, sharing and comparison of results with third parties. One of the ways to see the investigative activity of each medical specialty is through the presentations they make at scientific meetings. Aim: To describe the number of presentations of the different surgical specialties or areas in Chile in the main congress held at a national level and to assess whether the behavior was different during the years of the coronavirus pandemic. Material and Method: Bibliometric study of the Chilean Congress of Surgery between 2010 and 2021, evaluating the total number of presentations by surgical area, year of presentation and two categorized periods (2010 to 2019 and 2020 to 2021). Descriptive statistics and association analysis of publication means by area and period are performed. Results: 4,462 presentations were identified, including oral summaries, posters, videos, and residents' sessions, with a mean of 371.8 per year. Coloproctology and Gastroesophageal Surgery contributed a total of 616 (13.8%) and 598 (13.4%) respectively. The mean number of annual presentations prior to the coronavirus pandemic was 414, in contrast to the 160 annual works during it, with a significant decrease in the mean number of presentations per area from 27.6 (± 18.8) to 10.7 (± 8.69) (p < 0.001), without differences in their percentages of participation with respect to the total (p = 0.776). Conclusion: Coloproctology and Gastroesophageal Surgery are the most represented surgical areas. Although the contemporary period of the coronavirus pandemic meant a decrease in presentations, no change was observed in the percentage of participation in any particular area.

Feminismo, cuidado infantil y derechos de la infancia. Las feministas en los primeros congresos nacionales de Pediatría / Feminism, childcare and children's rights. Feminists in the first national paediatrics congresses

Analizando la participación de las mujeres en los primeros congresos de Pediatría, llama la atención que una buena parte de ellas pertenecían a organizaciones feministas y que, además de su militancia, tenían una preocupación por los y las menores, por sus aspectos educativos y legales.Se han revisado las actas y publicaciones relacionadas con los cinco primeros congresos nacionales de Pediatría (CNP) (1914-1933), biografías de las participantes y publicaciones sobre el feminismo en los años 20 y 30 del pasado siglo.En los cinco primeros CNP participaron 14 mujeres: un 15% eran del ámbito sanitario, un 65%, del educativo y un 29%, del derecho. Siete de ellas pertenecían a organizaciones feministas (50%). Hay dos generaciones de feministas que participaron en los CNP. La primera militó en la Asociación Nacional de Mujeres Españolas, donde la mayoría de ellas ostentaba cargos orgánicos y su labor profesional fue la educación. La segunda, en torno a Juventud Universitaria Femenina, y su dedicación laboral fue el derecho. Su participación en los CNP fue sobre esos temas, educación y derechos de la infancia. Así mismo, impulsaron otras actividades en defensa de la infancia a nivel social, como las 'cantinas escolares', los 'desayunos escolares' o el 'club infantil' de tiempo libre para las clases más desfavorecidas.Las mujeres que se han estudiado, desde su concepción feminista de la vida, no solo trabajaron por los derechos de la mujer, sino que se esforzaron por mejorar la vida de la infancia y el reconocimiento de sus derechos. (AU)

Analysing the participation of women in the first paediatric congresses, it stands out that many of them belonged to feminist organisations and that, in addition to the pursuit of their cause, they were concerned about children, including educational and legal aspects.We reviewed the minutes and publications related to the first five National Paediatric Congresses (NCPs) (1914-1933), biographies of the participants and publications on feminism in the 1920s and 1930s.Fourteen women participated in the first 5 NPCs, 15% from the health care field, 65% from the field of education and 29% from the field of law. Seven of them belonged to feminist organisations (50%). Two generations of feminists participated in the NPCs. Women from the first generation were actively involved in the National Association of Spanish Women, most of who held positions in administration and worked in the education field. Women from the second generation were organised around the Juventud Universitaria Femenina (University Young Women’s Organization) and worked in law. Their participation in the NPCs had to do with these issues, education and children’s rights. They also promoted other activities to advocate for children at a social level, such as the “school canteens”, “school breakfasts” or the “Children’s Club”, which provided leisure activities for disadvantaged groups.The women whose activity we reviewed, through their feminist perspective of life, not only worked for women’s rights, but also strove to improve the lives of children and to achieve the recognition of their rights.

Presentation to publication: Changes in paediatric radiology research trends 2010-2016.

BACKGROUND: More than half of paediatric radiology research presented at annual conference meetings between 2010-2012 remains unpublished. It is unclear if there are any improvements in this statistic despite some initiatives to improve awareness of the importance of evidence-based medicine. OBJECTIVES: To determine the abstract to publication rates (APRs) originating from recent paediatric radiology meetings, trends in research topics and factors associated with publication success. MATERIALS AND METHODS: All PubMed cited articles originating from oral presentations at European Society of Paediatric Radiology, Society for Paediatric Radiology or International Paediatric Radiology conferences between 2013-2016 were evaluated, and compared to those from previously published data from the same conferences dated 2010-2012. Publication rates, study design and topic as well as characteristics of the research group (e.g., author affiliations and number) were evaluated and compared between published and unpublished groups. RESULTS: The APR increased to 433/937 (46%) for abstracts presented between 2013-2016, compared to 300/715 (42%) in 2010-2012 (P=0.094). The largest proportion of publications comes from academic and tertiary centres (324/433 [75%]). International collaboration increased to 49/433 (11%) from 18/300 (6%) in 2010-2012 (P=0.018). A greater proportion of work was published within 12 months of conference: 41% in 2013-2016, compared to 29% in 2010-2012 (P=0.02). Paediatric Radiology remained the most popular destination journal, publishing 167/433 (39%) articles. CONCLUSION: There was a slight increase over time in the proportion of abstracts that resulted in publication, yet more than half of abstracts still do not reach publication status. Further work should identify how radiologists (particularly those outside tertiary and academic centres) can be supported to share their research.

Discussing around a virtual fire: Citizen engagement in a shared Decision-Making conference.

An online conference was organized to promote the Interprofessional Shared Decision-Making model and maximize its dissemination among stakeholders (citizens, health care providers, administrative staffs, policy makers, academics) in Canada. The goal was to enhance knowledge of and engagement in shared decision-making in a patient-oriented research, since shared decision-making has been hampered by reduced face-to-face contact, fear of infection, and overworked health professionals due to the COVID-19 pandemic. Therefore, we share a summary of what has been done to engage citizens in shared decision-making and to inform the interprofessional community about active citizen engagement in an online conference.
