Diversity of academic general medicine: A cross-sectional bibliometric study of original English-language research articles in general medicine and cardiology in Japan

ABSTRACT

Although research in general medicine is diverse, it has not been compared with research in a different medical specialty. The study aim was to understand the characteristics of research produced at Japanese university departments of general medicine and published in English-language journals, via comparison with another academic specialty, cardiology.In this cross-sectional study, a nationwide survey of the official websites of 82 university-affiliated medical schools in Japan was conducted in April 2020 to identify the heads of general medicine departments. We then surveyed the research output of these individuals in terms of original article output and research field diversity for journals listed in the Web of Science Core Collection of journals from 2010 to 2019. A similar survey of cardiology department publications was also conducted to provide a reference for intergroup comparisons and analysis of covariance.The analysis included 128 researchers from 78 general medicine departments and 96 researchers from 81 cardiology departments. The dominant research field of general medicine was general and internal medicine; that of cardiology was cardiac/cardiovascular systems. Data stratification by research field showed that general medicine researchers published significantly more articles than researchers in cardiology, a field that contains relatively few researchers. Furthermore, a comparison of individual researchers with the same number of published articles showed that researchers in general medicine departments published across a significantly wider range of fields than those in cardiology.This is the first study to describe the research characteristics of general medicine university departments in Japan through comparison with research in a different academic specialty. General medicine researchers in Japan comprise a heterogeneous group that mainly publishes research on general and internal medicine. Some general medicine researchers take a multidisciplinary approach to research and publishing.

A Bibliometric Analysis and Global Trends in Fascioliasis Research: A Neglected Tropical Disease

Background: Fascioliasis is a zoonotic neglected tropical disease caused by Fasciola hepatica and F. gigantica. In endemic regions, fascioliasis represents a huge problem in livestock production and significantly threatens public health. The present study was performed to assess the key bibliometric indicators, plot the global research outcome, and strive to find the research frontiers and trends in fascioliasis. Methods: A descriptive bibliometric and visualized study was conducted. The data were extracted from the Web of Science Core Collection (WoSCC) database. The WoSCC was searched using key terms covering a wide range of synonyms related to the causative agent (Fasciola) and the disease (fascioliasis). The database search was performed for the period from the inception of WoSCC until 3 October 2021. The downloaded data were exported into VOSviewer software version 1.6.17 for Windows to construct co-authorship countries, keywords co-occurrence, bibliographic coupling sources, and citation and documents network visualization. Results: A total of 4165 documents were included in this bibliometric analysis. The included documents were published between the years 1913 and 2021 from 116 countries, mainly from the United States of America (USA) (n = 482, 11.6%). The most prolific year was 2018 (n = 108). The journal that attracted the most publications was Veterinary Parasitology (n = 324), while the most productive author in this area was Rondelaud D (n = 156). In terms of total link strength (TLS), the most influential country was Spain (TLS = 236), followed by the USA (TLS = 178). Conclusion: This study is of value for veterinarians, doctors, and researchers to explore insights into research frontiers and trends in research on fascioliasis. The number of publications on fascioliasis has increased over time. Above 35% of publications have been produced by the USA, France, England, and Spain. "Fasciola hepatica" and "cattle" were the most dominant and widely used keywords. Research collaboration should be established among the researchers from developing countries with developed countries to learn new advancements and effective control strategies for fascioliasis.
