ABSTRACT
Background and aims: Liver transplant surgery has been performed in India for the last 25 years. We aimed to analyse the trends, characteristics, and key elements in the field of liver transplantation research from India. Methods: On April 23, 2023, we conducted a search of the Scopus database for the literature on liver transplantation research, using a well-defined search strategy. MS Excel and VOS viewer software programs were used to examine the articles for organisation, author, journal, keywords, and high-cited literature. Results: This analysis examined a total of 556 papers, which constituted only a 1.55% share of the global output. These papers involved 442 organizations, 1575 authors, and 147 journals. External funding was received in 4.13% and 23.56% were involved in international collaboration. Three Delhi-NCR organizations, namely the Medanta-The Medicity (n = 63), Institute of Liver & Biliary Sciences (n = 60), and Indraprastha Apollo Hospital (n = 48) led in publication productivity. M. Rela (n = 90) and A.S. Soin (n = 63) were the leading authors in publication productivity, while S. Sudhindran and P. Bhangui were the most impactful authors. Liver Transplantation (n = 96) and Journal of Clinical & Experimental Hepatology (n = 65) published the maximum number of these papers, whereas, Annals of Surgery and Journal of Hepatology led in the citation impact per paper. The most significant keywords were "Liver Transplantation" (n = 484), and "Living Donor" (n = 254). Only 1.80% (n = 10) of the papers were highly cited papers that received 50 to 142 citations and they together registered 69.9 citations per paper. Conclusion: Although the number of publications on liver transplantation from India started growing recently, it forms only 1.55% of the global report. There is an unmet need to increase government-supported research and multicenter collaborative studies at national and international levels for high-quality patient care.
ABSTRACT
Introduction: The non-alcoholic fatty liver disease (NAFLD) is common in the Indian Subcontinent. We aimed to examine the bibliometric characteristics of the publications arising from the countries of the Indian Subcontinent on NAFLD, over the last two decades. Methods: Publications on NAFLD from Indian Subcontinent during the period of 2001-2022 were retrieved from the Scopus database. Various important bibliometric parameters were studied from the retrieved publications and were exported to MS-Excel for analysis. VOSviewer software was used for analyzing co-author collaborative networks and keyword co-occurrence networks. Results: There is a rising trend of publications, especially in the last decade, with an average annual growth of 28.95% and an absolute growth of 526.21% between 2013 and 2022, compared to 2001-2012. From Indian Subcontinent's authors, 1053 papers were indexed in Scopus, with the majority (81.3%) being from India. Indian Subcontinent holds 13th rank globally with 3.43% share of global output. External funding was received for 15.76% publications and 24.59% papers were prepared with international collaboration, and these received much higher citations per paper. Research output is low, only 3.43% of global share. Regional research cooperation among countries of Indian subcontinent is also poor. Further, only 3.61% of papers were highly cited. Conclusion: Despite a high prevalence of NAFLD in Indian Subcontinent, the research output is low and of low impact. Further, the research collaboration between these Indian Subcontinent needs improvement.
ABSTRACT
INTRODUCTION: The paper analysis the performance of CSIR at the overall level as well as laboratory level in terms of various indicators during 2007-11. It identifies the strength and weakness of CSIR at the overall level as well as under laboratory level under 13 broad subjects. MATERIALS AND METHODS: The paper uses Scopes database for analyzing publications on CSIR and its 37 laboratories during 2007-11. RESULTS: The largest contribution of CSIR has been in the area of chemistry, followed by biochemistry, genetics and molecular biology, materials science, chemical engineering, physics, engineering, pharmacology, toxicology and pharmaceutics, agricultural and biological sciences, environmental science, medicine, earth and planetary sciences and energy.
ABSTRACT
This study analyses the research output of India in epilepsy research during 2002-11 on several parameters including the growth, rank and global publications share, citation impact, share of international collaborative papers, contribution of major collaborative partner countries, contribution of various subject-fields, contribution and impact of most productive institutions and authors, media of communication and characteristics of high cited papers. The Scopus Citation Database has been used to retrieve the data for 10 years (2002-11) by searching the keywords "epilepsy research" in the combined Title, Abstract and Keywords fields. Among the top 20 most productive countries in epilepsy research, India ranks at 11(th) position (with 1550 papers) with a global publication share of 2.88% and an annual average publication growth rate of 15.31% during 2002-11. Its global publication share has increased over the years, rising from 2.06% in 2002 to 4.65% during 2011. Its citation impact per paper was 2.77 during 2002-11, which decreased from 3.48 during 2002-06 to 2.41 during 2007-11. Its international collaborative publications share was 12.32% during 2002-11, which decreased from 12.45% during 2002-06 to 12.26% during 2007-11. Concludes that India needs to increase both the quantity and quality of research and also the need to share research data and stimulate national and international collaborative research, which will increase both the quantity and quality of research in epilepsy. There is a need to develop a national program on epilepsy as a part of national health plan, besides suggesting the funding agencies to establish a more ambitious funding program into the causes, prevention, cure and care of epilepsy. There is a need to build capacity at all levels of human resources for the management of epilepsy.
