Impact of Tweet Content on the Number of Retweets - "Tweet the Meeting 2022"

Background: Previous research has investigated the effectiveness of the "Tweet the Meeting" campaign, but the relationship between tweet content and the number of retweets has not been fully evaluated. Methods and Results: We analyzed the number of tweets and retweets during the Japanese Circulation Society's 2022 annual meeting. The ambassador group had significantly more session- and symposium-related tweets than the non-ambassador group (P<0.001), associated with the nubmer of retweets. Symposium-related tweets with figures generated more retweets than those without figures (mean [±SD] 3.47±3.31 vs. 2.48±1.94 retweets per tweet, respectively; P=0.001). Conclusions: The study revealed that official meeting-designated Twitter ambassadors disseminate more educational content than non-ambassadors, and generated more retweets.

Relationship Between Official Twitter Ambassadors and the Number of Retweets in the Annual Congress - "Tweet the Meeting"

Background: The relationship between Twitter ambassadors and retweets has not been fully evaluated for “tweet the meeting” activity.

Methods and Results: We collected data on the number of tweets and retweets during the Japanese Circulation Society’s (JCS) annual meetings in 2019, 2020, and 2021. After adjustment, JCS Twitter Ambassadors, selected by the JCS to increase the meeting’s visibility, increased the total number of retweets by 9%.

Conclusions: This is the first report on the numerical relationship between JCS Twitter Ambassadors and the total number of retweets during an annual congress. Original tweets by JCS Twitter Ambassadors increased the number of retweets, but retweets by influencers were more effective at stimulating social media engagement.

Two-Year Experience in "Tweeting the Meeting" During the Scientific Sessions - Rapid Report From the Japanese Circulation Society

Background: Twitter has become increasingly popular at annual medical congresses as a platform to communicate to attendees. The aim of this study is to reveal the twitter usage in the annual congress of the Japanese Cirsulation Society. Methods and Results: We compared the total number of tweets during the Japanese Circulation Society's annual meetings in 2019 and 2020. The total number of tweets increased from 7,587 in 2019 to 23,867 in 2020. Most tweets were retweets (>70%), and approximately half of Twitter users tweeted only once. Conclusions: Twitter usage during the Japanese Circulation Society's annual meeting increased from 2019 to 2020, and a large number of tweets were from Twitter ambassadors of the Japanese Circulation Society. However, further evaluation is needed, with future studies investigating the usefulness of this platform.

Highlights of the 30th Annual Congress of the EANM, Vienna 2017: "Yes we can - make nuclear medicine great again"

The 30th Annual Congress of the European Association of Nuclear Medicine (EANM) was held in Vienna, Austria, from 21 to 25 October 2017 under the chairmanship of Professor Francesco Giammarile. As always, the Congress was a great success: more than 6,379 participants came from 90 countries from all continents. Participants were presented with an excellent programme consisting of symposia, and scientific and featured sessions, CME sessions, and plenary lectures. These lectures were devoted to nuclear medicine imaging and therapy, including hybrid imaging and molecular life sciences. Additionally, the latest technology and innovations in the field were presented, and added to the success of the Congress. This review summarizes the major scientific contributions which were selected from more than 1,900 submitted abstracts, and presented in the closing highlights session. They cover the diverse areas of nuclear medicine, with particular focus on oncology, cardiovascular science, neurology, technological innovation and novel tracers, and also other clinical sciences. A particular focus of the Congress was on targeted radionuclide-based therapies, which all show promising and great innovations. The Congress was a unique opportunity to be thoroughly updated on this research. This Highlights Lecture could only be a brief summary of the large amount of data presented and discussed during the meeting, which can be found in much greater detail in the Congress proceedings book, published as volume 44, supplement 2 of the European Journal of Nuclear Medicine and Molecular Imaging in October 2017.
