Symposium on molecular radiotherapy dosimetry: The first of a series?

The EFOMP Special Interest Group for Radionuclide Internal Dosimetry (SIG_FRID) organised its first scientific meeting, the Symposium on Molecular Radiotherapy Dosimetry, in Athens on November 9th-11th 2023. The Symposium was hosted by the Hellenic Association of Medical Physicists and the National and Kapodistrian University of Athens. This meeting gathered more than 180 scientists from 28 countries. Scientific, clinical and regulatory aspects were addressed by 8 invited experts. Two continuous professional development sessions were organised. A special round table gathering medical physics experts, physicians regulatory authority experts and patient representatives addressed the possibilities to increase clinical dosimetry dissemination. The event was supported by companies and a specific industry session allowed sponsors to present their products, innovations and future perspective in this field.

Welcome to the 2024 ACMT Annual Scientific Meeting.

Two hundred sixteen abstracts were selected for presentation at the 2024 American College of Medical Toxicology (ACMT) Annual Scientific Meeting on April 12-14, 2024, in Washington, DC. The quality and breadth of toxicology scholarship continues to grow as our field expands. The complete 2024 ASM abstract book in the April issue of JMT includes original research studies from around the world and the ToxIC Investigators Consortium, clinically significant case reports describing toxicologic phenomena, and selected encore research presentations from other scientific meetings.

When to Attend a Webinar?

OBJECTIVE: To determine the most appropriate delay to start a webinar. METHODS: This cross-sectional study was conducted on weekly general staff scientific webinars held by the Institute of Human Virology (IHV), University of Maryland School of Medicine, Baltimore, USA. 35 observations were made at arbitrary chosen times of three consecutive IHV webinars. After standardizing the number of participants, a 4th-degree polynomial fit was applied to the data. A cost function was defined as the sum of the time wasted for those who attended the webinar early and the lost for those who attend with delay. The cost function was minimized to compute the most appropriate delay to start the webinar. RESULTS: The model could explain almost 95% of the observed variance in the number of participants. Normally, half of the participants attended the meeting at the webinar set starting time. The cost was a minimum if the webinar was delayed for about 3 minutes. CONCLUSION: It seems that the most appropriate time for starting the IHV general staff meetings is around 3 minutes after the webinar set starting time.

How to Present Your Research Findings at a Scientific Meeting.

The next step following acceptance of an abstract submitted for a scientific meeting is to create the poster. Poster presentations provide an avenue for dissemination of research findings as well as the opportunity to highlight the work and network with other clinicians. Requirements for poster presentations vary among scientific meetings. Therefore, it is important to follow instructions set forth by the specific conference at which the work will be presented. Important considerations for poster design include the elements it should contain, font type and size, use of tables and figures, and poster size. Research indicates visual appeal has a greater influence in attracting attention than content. In addition to creating the poster, preparing for presentation is an essential step in the process. Practicing the presentation prior to the meeting, anticipating questions, and being familiar with the poster content are principal factors in preparing for the presentation. Oral presentations for posters are typically brief and should only focus on the key points. The purpose of this paper is to review poster design and provide general guidelines for presenting an abstract at a scientific meeting.

Fostering the Next Generation of Researchers: a Sustainable Mentoring Program for Early Career Toxicologists in Scientific Abstract Review.

The presentation of abstracts at scientific meetings is an important step in the dissemination of scientific discovery. Most scientific meetings recruit volunteer experts to evaluate and score submitted abstracts to determine which ones qualify for presentation. Reviewing an abstract is an important service to one's specialty, but there is typically no formal training or required instruction during medical toxicology fellowship on scientific abstract scoring. In order to provide structured training in abstract review, the American College of Medical Toxicology (ACMT) Research Committee launched the Annual Scientific Meeting (ASM) Abstract Review Mentor program in 2021. The goals of this program were to train fellows how to score scientific abstracts and provide them with new mentor connections to toxicologists outside of their training program. After evaluating 3 years of data from participating fellows-in-training and faculty mentors, we conclude that ACMT's Abstract Review Mentor program was successful in training future reviewers and fostering external mentorship relationships. All participants reported their experience in this program will change how they submit future abstracts to scientific meetings, help their future service as an abstract reviewer, and motivate their involvement in other specialty-related research activities. Implementing an abstract review training program is sustainable and a vital strategy for enhancing the dissemination of scientific discovery and training the next generation of medical toxicology researchers.

Reviewer Feedback for Abstract Submissions to the Pediatric Academic Societies Meeting: A Pilot Project.

PURPOSE: To describe and evaluate a pilot project to provide reviewer comments to authors who submitted abstracts to the Hospital-based medicine topic area for the Pediatric Academic Societies (PAS) 2021 annual meeting METHODS: Abstract reviewers were encouraged via email to include reviewer comments for authors in their abstract reviews. Unedited comments were emailed to authors shortly after the abstract decision notifications were sent. We quantified the number of reviewers who commented per abstract. Additionally, we surveyed authors and reviewers to evaluate the perceived impact of the pilot project. RESULTS: For 123 abstracts submitted to the Hospital-based medicine topic area, every abstract received comments from at least one reviewer, and a median (IQR) of 4 (3-5) reviewers commented per abstract. The response rates for the author and reviewer surveys were 61/114 (54%) and 54/84 (64%), respectively, and both groups of respondents generally favored the pilot program. The majority of authors (59%) made changes to their project based on the feedback provided and 96% reported that they would like to continue to receive reviewer feedback for future PAS abstract submissions. Reviewers reported spending a mean of 11 minutes reviewing each abstract. Most (85%) felt that they spent the same or slightly more (1%-25%) time reviewing than in prior years. Multiple open-ended comments were provided, largely positive. CONCLUSION: A pilot program to incorporate reviewer feedback into abstract decision notification for a large national research meeting was successful. This approach should be considered for future meetings to enhance this integral component of academic development.

Charting the course from abstract to published article.

OBJECTIVE: Abstracts act as short, efficient sources of new information. This intentional brevity potentially diminishes scientific reliability of described findings. The authors' objective was to 1) determine the proportion of abstracts submitted to the American Association of Neurological Surgeons (AANS) annual meeting that subsequently are published in peer-reviewed journals, 2) assess AANS abstract publications for publication bias, and 3) assess AANS abstract publications for differing results. METHODS: The authors screened all abstracts from the annual 2012 AANS meeting and identified their corresponding full-text publication, if applicable, by searching PubMed/MEDLINE. The abstract and subsequent publication were analyzed for result type (positive or negative) and differences in results. RESULTS: Overall, 49.3% of abstracts were published as papers. Many (18.1%) of these published papers differed in message from their original abstract. Publication bias exists, with positive abstracts being 40% more likely to be published than negative abstracts. The top journals in which the full-text articles were published were Journal of Neurosurgery (13.1%), Neurosurgery (7.3%), and World Neurosurgery (5.4%). CONCLUSIONS: Here, the authors demonstrate that alone, abstracts are not reliable sources of information. Many abstracts ultimately remain unpublished; therefore, they do not attain a level of scientific scrutiny that merits alteration of clinical care. Furthermore, many that are published have differing results or conclusions. In addition, positive publication bias exists, as positive abstracts are more likely to be published than negative abstracts.

Lessons Learned from In-Person Conferences in the Times of COVID-19.

Scientific societies and conference secretariats have recently resumed in-person meetings after a long pause owing to the COVID-19 pandemic. Some safety measures continue to be implemented at these in-person events to limit the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). With increased numbers of waves of infection, caused by the emergence of SARS-CoV-2 variants, additional information is needed to ensure maximal safety at in-person events. The MEX-DART case study was conducted at the in-person Hep-DART 2021 conference, which was held in Los Cabos, Mexico, in December 2021. Many COVID-19 safety measures were implemented, and incidence of SARS-CoV-2 infection during the conference was tested onsite. In this study, we highlight the specific conditions and safety measures set in place at the conference. In addition to vaccination requirements, social distancing, and mask wearing, daily rapid testing was implemented for the duration of the conference. At the end of the 4-day meeting, none of the 166 delegates (and family members attending the conference) had tested antigen positive for SARS-CoV-2. Two delegates tested positive in the week after the conference; the timing of their positive test result suggests that they contracted the virus during their travels home or during postconference vacationing. We believe that this model can serve as a helpful template for organizing future in-person meetings in the era of COVID-19 and any other respiratory virus pandemics of the future. While the outcomes of this case study are encouraging, seasonal surges in respiratory virus infections such as SARS-CoV-2, RSV, and influenza virus incidence suggest that continued caution is warranted.

Analysis of challenges faced and the scientific content of a hybrid pediatric surgical conference arranged during the COVID-19 pandemic.

BACKGROUND: Scientific conferences which are considered as an important event for dissemination of research and related academic activities were badly affected during the COVID-19 pandemic. Virtual format for interaction was used as an alternative method to continue such academic discourse. However, this did not provide the same level of communication and interest as that of in-person meetings. With evolving knowledge about the COVID-19 pandemic especially its transmission, role of vaccine, and observing standard operating procedures (SOPs), fear among healthcare providers is mitigated to some extent. Keeping in mind the importance of scientific conferences in the context of sharing knowledge and its impact on the training of faculty members and postgraduate residents, a hybrid conference was planned by the national association of pediatric surgeons.The purpose of this study was to retrospectively review the challenges faced during the organization of this conference as well as to analyze the pattern of registration, number of abstracts received, the gender of the participants and their status, region of the country they represented, type of presentation made, and scientific subject covered. SPSS version 22 was used for data entry. Descriptive and inferential statistics were used to present data. Chi square test was applied to find out the association between categorical variables and a p value < 0.05 was considered as significant. RESULTS: A total of 170 pediatric surgeons and postgraduate residents participated from all over the country and abroad. Nearly half (47.1%) of the registrants were postgraduate residents. Most of the participants (90%) opted for in-person attendance. The venue was selected with a capacity to house more than double the number of registrants with provision of safe distance. Availability of face masks, gloves, and sanitizers was ensured by the organizers. Packed meal boxes were arranged and served at the venue site in an open place on the terrace. A total of 97 abstracts were accepted for presentation that included 57 (58.8%) long oral podium and 40 (41.2%) poster presentations. Most of the studies (n=48-49.4%) were related to the subject of gastroenterology including pancreatico-hepatobiliary system and spleen. Majority of the presenters were male (p = 0.046) and postgraduate residents (p = 0.001). CONCLUSION: It was possible to organize a hybrid annual medical conference where most of the participants preferred physical presence. A rich scientific program was made to cater the needs for pediatric surgical fraternity. Residents made attractive presentations. It was noted that physical presence during clinical conference produced effective communication and learning.

Prof. Dimitar Hrisoho, Md, Phd, Founder of Nephrology in the R. N. Macedonia.

Prof. Dr. Dimitar T. Hrisoho was born on June 11, 1924 in Bitola, R. Macedonia. He died in Struga on September 22, 1986, and was buried in Skopje. He completed primary and secondary education in Bitola. He graduated from the Medical Faculty in Belgrade in 1951 as one of the best students of his generation (average grade of 9.75). In 1953 he was employed at the Internal Clinic of the Medical Faculty in Skopje, where in 1955 he passed the specialist exam in internal medicine. He successfully defended his habilitation "Polyarthritis chronica evolutiva" and his doctoral dissertation "Clinical features of Vitina nephropathy". The doctoral dissertation indicates that Vitina nephropathy is a new site of the Balkan Endemic Nephropathy entity and that more genetic testing of patients were needed. Based on numerous clinical and scientific researches published in over 200 papers, he was elected a Full Professor of internal medicine at the Medical Faculty of the Ss. Cyril and Methodius University in Skopje in 1971. In 1970, he formed the nephrology section of the Macedonian Medical Association (MMA), which grew into the nephrology Association of MMA. Through the Association, the education of the medical staff from the field of nephrology was performed. He also set up a bio-cybernetics association. He achieved his vision and desire to transfer and apply the achievements of modern nephrology in the diagnosis and treatment of kidney patients in Macedonia at the Clinic of Nephrology of the Medical Faculty in Skopje, which was the first specialized institution established for examination and treatment of kidney patients in the former Yugoslavia and the Balkans. The Clinic educated nephrological staff and examined and treated kidney patients with new methods and drugs that positively affected the development of nephrology as a subspecialty of the internal medicine. D. Hrisoho was actively involved in the introduction of new methods for examination of kidney patients, as well as in the treatment of patients with acute and chronic renal insufficiency with dialysis since 1965. He also participated in the first two kidney transplantations from living donors performed in 1977. He wrote a chapter on "kidney examination", printed in the book of Prof. A. J. Ignjatovski "Fundamentals of Internal Propedeutics" Part III, published by "Prosvetno delo", 1963, in Skopje. This is the first text to investigate a patient with kidney disease published in a textbook in R. Macedonia. In 1984 he published the textbook "Clinical Nephrology" printed by the University of the Ss. Cyril and Methodius University in Skopje. Prof. D. Hrisoho organized the First Scientific Meeting of Yugoslav Nephrologists with international participation, from 26 to 28 September 1977, in Struga, R. Macedonia. The meeting was attended by prominent nephrologists from the former Yugoslavia, the Balkans, Europe and the United States, among them: J.S. Cameron from UK, J.L. Funck-Brentano from France, M. Burg and P. Ivanovich from the USA, R. Kluthe from Germany and A. Puchlev from Bulgaria. The scientific meeting was the largest nephrology event until then organized in the former Yugoslavia. The meeting provided an exchange of experiences with world-renowned nephrologists. D. Hrisoho presented the paper Artificial intelligence in nephrology. The author tried to apply bio-cybernetics in nephrology. Prof. D. Hrisoho was Vice Dean of the Medical Faculty in Skopje in the period 1963-1965 and Vice Rector of the University of the Ss. Cyril and Methodius University in Skopje in the period 1974-1975. Prof. Hrisoho was also active in socio-political organizations. For his medical, educational and scientific activities he received several awards and recognitions in the country and abroad. Thus, the work of Prof. D. Hrisoho was permanently embedded in the nephrology of R. Macedonia.

Transitioning to Virtual: ACMT's 2020 Annual Scientific Meeting.

The American College of Medical Toxicology (ACMT) 2020 Annual Scientific Meeting (ASM) was scheduled to be held in New York City, March 12-15, 2020, and had the largest conference registration in the history of ACMT's ASM. In the week prior to the conference, the severity of the COVID-19 pandemic in New York City and the USA was becoming apparent. On the first day of the conference, organizers canceled the live portion of the meeting and converted the conference into an entirely virtual meeting. We discuss the challenges of holding a virtual conference, future directions for online meetings, and why our conference was ultimately successful.

The voyage: Amalgating a social media platform through the annual scientific meeting.

Social media platforms are increasingly used by professional societies for improved member engagement, to raise awareness, for advocacy and for widespread dissemination of scientific meeting highlights. This article describes the inaugural social media campaign implemented at the American Society of Nuclear Cardiology (ASNC) 2019 Scientific Meeting. Campaign strategies, including development of an interactive social media curriculum, dedicated social media ambassadors and implementation and announcement of a Tweetup, are described in detail. These efforts resulted in significantly uplifting the profile of the conference, improving attendee engagement, reinforced conference highlights, and expanded meeting reach across the world. This manuscript provides a blueprint for other professional societies considering the launch of a Social Media campaign at their scientific meetings.

Factors affecting publication in peer-reviewed journals of abstracts presented from 2008 to 2012 ACVO meetings.

PURPOSE: To examine variables that affect publication of ACVO meeting abstracts in peer-reviewed journals and compare results to ECVO publication rate (PR). METHODS: Published papers were identified via online searches for abstracts from 2008 to 2012 ACVO/ECVO meetings. Variables analyzed (via Pearson's chi-Squared test) included the following: oral presentation/poster, type of abstract (clinical/basic science/case report), species, ocular tissue, nationality, funding, first/last/any author a diplomate, resident as first author, and author affiliation (private practice/university). RESULTS: One hundred and eighty-six of 577 ACVO abstracts were published within 608 ± 479 days, with 103 published in Veterinary Ophthalmology. Significant factors included the following: nationality of first/last authors (P = .005); English as first language (P < .001); presentation type (P < .001, oral 40% PR, poster 22% PR); type of study (P = .037, clinical study 35% PR, basic science 30% PR, case report 16% PR); resident as first author (P < .001); diplomate as any author except first/last (P < .001); first author affiliation (P = .001, university 37% PR, practice 21% PR); last author affiliation (P = .003, university 36% PR, practice 22% PR); and species (P < .001, horses 53% PR, multiple species 50% PR, cats 35% PR, food animals 31% PR, exotics/wildlife 31% PR, dogs 27% PR, laboratory animals/in vitro 24%). Nonsignificant factors were as follows: diplomate as first/last author, funding, and ocular tissue. Presentation type, resident as first author, university affiliation of first author, and species had the greatest effect on publication probability. For the same period, ECVO PR was 87 of 299, which was not significantly different from ACVO PR (P = .342). CONCLUSION: At 32%, ACVO PR for the study years is similar to ECVO PR of 29%.

Factors affecting peer-reviewed publication of abstracts presented at meetings of the European College of Veterinary Ophthalmologists (2008-2012).

PURPOSE: To review abstracts presented at five consecutive meetings of the European College of Veterinary Ophthalmologists (ECVO), and identify abstract characteristics that affect the probability of their publication in peer-reviewed journals. METHODS: An online search was conducted for peer-reviewed publications (PRPs) stemming from abstracts from five ECVO meetings (2008-2012). Time to publication and journal were noted. Effects of ocular tissue/discipline, species, type of presentation and study, funding acknowledgment and affiliation, professional qualifications, and nationality of the first and last authors on probability of publication were analyzed. RESULTS: Of presented abstracts, 29% (87/299) were published as PRPs in Veterinary Ophthalmology (n = 50), other veterinary journals (n = 22), and nonveterinary journals (n = 15). During the 5 years studied, there was no significant difference between the impact factor of Veterinary Ophthalmology and the 25 other journals in which PRPs were published (P = 0.369). Median time to PRP acceptance or publication was 468 days. Independent variables most significant in determining the probability of PRP were oral presentation (P = 0.002), resident authorship (P < 0.0001), and species (P = 0.002), with food animal abstracts having the highest odds ratio. Ocular tissue/discipline (P = 0.13) and type of study (P = 0.33) did not affect publication probability. Funding acknowledgment (P = 0.02), author nationality (P = 0.02), and academic affiliation (P = 0.04) were also significant factors. CONCLUSIONS: Publication rate of ECVO abstracts is lower, but time to publication is similar, compared with most biomedical meetings.

These are the abstracts of the 2017 American College of Medical Toxicology (ACMT) Annual Scientific Meeting. Included here are 120 abstracts that will be presented in March 2017, including research studies from around the globe and the ToxIC collaboration, clinically significant case reports describing new toxicologic phenomena, and encore presentations from other scientific meetings.

Level of clinical evidence presented at the open and closed American Shoulder and Elbow Surgeons annual meeting over 10 years (2005-2014).

BACKGROUND: The American Shoulder and Elbow Surgeons (ASES) annual scientific meetings are premier forums whereby orthopaedic surgeons are informed of the latest research advances in shoulder and elbow surgery. The purpose of the present study was to assess the Level of evidence (LOE) in the clinical papers presented at both the open and closed ASES annual scientific meetings from 2005 to 2014. Secondarily, the study evaluated whether there were any changes in the distribution of LOE over this period of time. METHODS: Two reviewers independently evaluated the abstracts of 532 paper presentations at either the open or closed ASES annual meetings. The independent reviewers first screened the abstracts for clinical evidence and excluded cadaveric, biomechanical, technique, and review studies. The included abstracts were then independently graded for methodological quality using LOE from Level I (highest quality) to IV (lowest quality) based on the classification system created by The American Academy of Orthopaedic Surgeons (AAOS). RESULTS: Overall, 421 presentations were included and graded for LOE. In general, 17% of the presentations were graded level I; 15% level II; 25% level III; and 43% assigned a LOE of IV. Chi-square analysis demonstrated a statistically significant improvement in the LOE of presentations at the open and closed ASES meetings combined (p = 0.028) between the years 2005 and 2014. In particular, the proportion of presentations graded as level IV significantly decreased over this period (p = <0.001). CONCLUSIONS: While most presentations at the ASES annual scientific meetings were of lower LOEs the percentage of level I evidence is greater than that reported at other Orthopaedic meetings. There has been a significant improvement in the LOE of clinical research at open and closed ASES meetings from 2005 to 2014. Specifically, the proportion of level IV studies have dramatically decreased over time.

Anthelmintics: From discovery to resistance II (San Diego, 2016).

The second scientific meeting in the series: "Anthelmintics: From Discovery to Resistance" was held in San Diego in February, 2016. The focus topics of the meeting, related to anthelmintic discovery and resistance, were novel technologies, bioinformatics, commercial interests, anthelmintic modes of action and anthelmintic resistance. Basic scientific, human and veterinary interests were addressed in oral and poster presentations. The delegates were from universities and industries in the US, Europe, Australia and New Zealand. The papers were a great representation of the field, and included the use of C. elegans for lead discovery, mechanisms of anthelmintic resistance, nematode neuropeptides, proteases, B. thuringiensis crystal protein, nicotinic receptors, emodepside, benzimidazoles, P-glycoproteins, natural products, microfluidic techniques and bioinformatics approaches. The NIH also presented NIAID-specific parasite genomic priorities and initiatives. From these papers we introduce below selected papers with a focus on anthelmintic drug screening and development.

Can rasch analysis enhance the abstract ranking process in scientific conferences? Issues of interrater variability and abstract rating burden.

INTRODUCTION: Abstract ranking processes for scientific conferences are essential but controversial. This study examined the validity of a structured abstract rating instrument, evaluated interrater variability, and modeled the impact of interrater variability on abstract ranking decisions. Additionally, we examined whether a more efficient rating process (abstracts rated by two rather than three raters) supported valid abstract rankings. METHODS: Data were 4016 sets of abstract ratings from the 2011 and 2013 national scientific conferences for a health discipline. Many-faceted Rasch analysis procedures were used to examine validity of the abstract rating instrument and to identify and adjust for the presence of interrater variability. The two-rater simulation was created by the deletion of one set of ratings for each abstract in the 2013 data set. RESULTS: The abstract rating instrument demonstrated sound measurement properties. Although each rater applied the rating criteria consistently (intrarater reliability), there was significant variability between raters. Adjusting for interrater variability changed the final presentation format for approximately 10-20% of abstracts. The two-rater simulation demonstrated that abstract rankings derived through this process were valid, although the impact of interrater variability was more substantial. DISCUSSION: Interrater variability exerts a small but important influence on overall abstract acceptance outcome. The use of many-faceted Rasch analysis allows for this variability to be adjusted for. Additionally, Rasch processes allow for more efficient abstract ranking by reducing the need for multiple raters.

Publication rate of abstracts presented at the Canadian society of otolaryngology- head and neck surgery annual meetings: a five year study 2006-2010.

BACKGROUND: To determine the rate of publication in a peer-reviewed journal for all oral presentations made at the Canadian Society for Otolaryngology- Head and Neck Surgery's Annual Meetings from 2006-2010. METHODS: All abstracts were searched by keywords and authors' names in Medline via PubMed and Google Scholar. Authors of presented abstracts not found to be published were contacted directly for further information. RESULTS: 50.5% of presented abstracts (n = 198) were subsequently published with an average time to publication of 21 months. For those abstracts found not to be published 74.6% (n = 167) of authors responded with further information about their research, 66% (n = 89) of abstracts with author response that were not published were never submitted for publication. Authors' main reasons for not publishing were that the research was still in process (34%, n = 21) or that a resident or fellow working on the project "had moved on" (26%, n = 16). CONCLUSION: The publication rate for the Canadian Society for Otolaryngology- Head and Neck Surgery's Annual Meetings from 2006-2010 is within the range reported by other conferences and specifically other Canadian conferences in different specialties; however, roughly half of presentations went on to be published. The main barrier to publication was bringing projects to the submission stage and not rejection by journals. Resources such as more time for research or personnel to coordinate projects may result in a greater rate of project completion.
