RESUMO
Background: Schizophrenia is a chronic mental illness that affects millions of individuals worldwide. The etiological origin of schizophrenia is heterogeneous, but it has been shown to be associated with dysfunction in serotonin activity, serotonin receptors, and serotonin metabolism in the brain. Bibliometric analysis is a tool used to scrutinise and analyse research activities and evidence in a specific research area. No existing bibliometric analyses have considered both serotonin and schizophrenia. Methods: We conducted a bibliometric analysis including 12,027 studies related to the schizophrenia-serotonin link published from the inception of the study to 2023 and available in the Scopus database. We used VOSviewer software to identify global trends, analyse the author and editors keywords, the most cited articles and author, as well as the most productive institutes and journals publishing research on schizophrenia-serotonin link. Results: Most publications related to the link between schizophrenia and serotonin are focused on adult humans and examine topics such as antipsychotic agents, depression, and serotonin uptake inhibitors. The Journal of Clinical Psychiatry has published the most papers on the schizophrenia-serotonin relationship. Among nations, the United States is the leader in publications. King's College London is the institution with the highest number of publications, and H. Y. Meltzer is the most influential author. Growing trends in schizophrenia-serotonin research are personalised medicine, alternative medicine, transcranial magnetic stimulation, artificial intelligence, nervous system inflammation, brain-gut axis, and the gut microbiome. Conclusion: Since 1950, there have been several fluctuations in the number of published studies related to schizophrenia and serotonin. We believe that the development of novel medications and treatments for schizophrenia will be increased in the future, as well as research into genetic risks, psychological factors, and cranial neuroimaging components. Future schizophrenia and serotonin research is likely to focus on personalised medicine, alternative therapies, novel pathogenesis of schizophrenia, and the use of emerging technologies such as artificial intelligence.

Background: Helicobacter pylori (H. pylori) infection is prevalent and associated with the development of various gastric diseases. On the other hand, inflammatory bowel disease (IBD) is an immune-related intestinal disorder influenced by factors like gut microbiota imbalance, genetic predisposition, and environmental influences. Despite extensive research on the H. pylori-IBD relationship, a comprehensive bibliometric analysis in this area is lacking. Therefore, this study aims to use bibliometric methods to explore research trends, hotspots, and frontiers in H. pylori and IBD-related research, offering valuable insights for future research and clinical practice. Methods: We retrieved relevant literature on H. pylori and IBD from the Web of Science Core Collection (WoSCC) and Scopus databases covering 2007 to 2024. We perform a comprehensive analysis within the WoSCC literature. We compare these findings with relevant results from Scopus. Results: Research on H. pylori and IBD has remained prominent in recent years. The United States leads in output, with strong contributions from authors, institutions, and journals. China, despite being a developing country, shows rapid article growth, signaling growing research potential. Key topics include Crohn's disease, gut microbiota, H. pylori infection, and ulcerative colitis. Newer interests include health, cancer prevention, and chronic gastritis. Conclusion: Over the past, research on H. pylori and IBD has primarily centered around epidemiology and clinical studies. The question of whether H. pylori definitively offers protective effects against IBD remains unresolved. Therefore, further investigation could explore the underlying mechanisms of their relationship or initiate long-term prospective cohort studies to gather more compelling evidence.

RESUMO
Trypanosoma and Leishmania species are responsible of a range of Neglected Tropical Diseases (NTDs) from disfiguring conditions to fatal processes in humans. Both genera also affect wild and domestic animals causing diseases of public health significance and high economic impact on farm economy of developing areas. Japan has been actively involved in overseas cooperation and the country has a large scientific community. However, there is no information on the scientific output of Japanese scientists and institutions on these two NTDs. To explore the Japanese contribution and its profile, we have mined Web of Science database from 1971 to 2022 the articles by Japanese scientists, scientific areas and institutions, time-related variations of these parameters, and involvement in cooperation activities with foreign scientists. Research on Trypanosoma has been present in all the studied period, with higher production, whereas Leishmania-related activities showed a delay. A steady increased of Japanese scientific output was found up to the beginning of 2000s, whereas a certain stagnation was found in the present century. Low growth rate of research output on these two NTDs by Japanese authors in the 21st century is not correlated neither to the pattern found globally nor the situation in other parasitic infections. Thus, other elements should be considered in future analysis including the actual number of scientists involved and the available funding. Reinforcement of research groups from Japanese institutions and widening the scope of collaborations, particularly with health and academic centers from endemic regions, could trigger the Japanese productivity in the research area.
