Global trends and hotspots in recent neurotrauma-related research in war-stricken countries: A bibliometric and...

The increase of interest in neurotrauma is growing worldwide due to the increase in military conflicts in war-stricken countries around the globe. There is an increasing trend of publishing about it worldwide. We aim to sort out the topic trends in the field of neurotrauma in countries experiencing military conflicts from the perspective of bibliometrics in the last 3 years, from 2020 to 2023. This will provide a status update on the current situation of publication productivity on the related topic, while simultaneously studying the potential effect of COVID-19 pandemic on it.

We looked into articles and reviews published between 2020 and 2023 in Scopus based on predefined inclusion criteria which included neurotrauma-related publications sourced or co-authored by authors from war-stricken countries. 80 articles were included in the final analysis. The global research publication output, contributions of countries, institutions, journals, authors, average citation index (ACI), and keywords were analyzed.

There was a rise in publication productivity in 2020, which declined in 2021 and then again increased in 2022 onward. The United States published the largest number of articles either sourced or co-authored with authors from war-stricken countries (32/80, 40%) while Russia had the highest total citations (70). The order of countries with the highest ACI was Azerbaijan (18.5) followed by Spain and Egypt (14.7). The American University of Beirut was the most prolific institution. It had the highest number of publications (8) and citations (41). Gardner R.C. was the author with the most publications (3), followed by F. Anwar, M. N. Kravtsov, and R. Darwazeh. (2). World Neurosurgery had the most publications (6), but Frontiers in Surgery was the most impactful journal (ACI = 4.5). The most recent keywords predominantly revolve around topics such as "traumatic brain injury" (occurred 22 times) followed by rehabilitation' (6), veterans (4) and humanitarian activities (3). There were significant collaborations among developed countries and war-stricken countries for publications related to the topic.

An increasing trend in publications regarding neurotrauma in war-stricken countries was seen. Enhanced collaborations tell us about the combined interest of countries, irrespective of being at peace or at war. Our findings could provide useful information to identify potential research fronts in the coming years.
