Social media platforms are essential for online scholarly activities in the time of the COVID-19 pandemic. Their use is critical in countries of non-mainstream science. This study aimed to evaluate the role of social media in scholarly activities in Eastern Europe. We collected responses from 127 scholars from Ukraine, Poland, Lithuania, and other Eastern European countries. They mainly reported spending 1–2 hours on social media activities. ResearchGate, Facebook, and LinkedIn were the most popular channels for post-publication article promotion. Only 17.3 % of respondents were familiar with metrics
generated by Altmetric.com and Plum Analytics. Increasing awareness of the role of social media platforms and metrics for scholarly purposes requires more attention in Eastern Europe.

2023 marks the 125th anniversary of the foundation of the Medical Commission of the Shevchenko Scientific Society’s publication, whose successor today is the journal Proceedings of the Shevchenko Scientific Society. Medical Sciences (Medical Sciences, ISSN 2708-8634; eISSN 2708–8642). Dr Eugen Ozarkevych, the founder and later the Chair of the Shevchenko Scientific Society’s Medical Commission in Lviv, initiated the publication of the scientific and practical journal “Medical Collection” («Лікарський збірник») in 1898. The journal’s primary purpose was to promulgate scientific achievements in the field of medicine in Ukrainian and to create Ukrainian medical terminology. This format allowed the reader to review scientific achievements in fundamental and clinical medicine, current medical problems, and new methods to in the prevention, diagnosis and treatment of various diseases. Ukrainian professional medical terminology was presented in this journal for the first time. Throughout its existence, this oldest medical journal, Medical Sciences, remains faithful to its historical multidisciplinary orientation. During the information and Russian war on the territory of Ukraine, Medical Sciences serves as a national heritage of Ukraine. It is recognized by international partners and indexed in scientometric bibliographic databases such as Scopus, Copernicus, Directory of Open Access Journals (DOAJ), and Google Scholar. As an Open Access Journal, it is read in 155 countries of the world.
