Background: The prevalence of childhood obesity (CHO) has gradually increased in India over the past two decades and has necessitated advanced research to address it. Assessing CHO-related research conducted so far is necessary to guide future research. However, a bibliometric assessment of Indian CHO research is unavailable. Aim: The study aimed to map the CHO research published in India during the last two decades. Materials and Methods: The publication data was retrieved from Elsevier's Scopus database using a predefined search strategy. The quality of publications was assessed using indicators such as citations per paper (CPP), relative citation index (RCI), and Hirsch index (HI). Results: India contributed 705 (1.8%) to a global total of 37,762 publications and is currently ranked 15th in CHO-related research; the top 3 countries are the USA, UK, and Australia with 38.1%, 9.6%, and 6.5% publication share respectively. The annual growth in India's publications was 27.4% compared to the global average of 8.7%. The research quality has declined (average CPP 50.6 during 2002-2011 and 25.4 during 2012-2021). Only 25.2% of publications were internationally collaborative. The most productive organizations were AIIMS, New Delhi, PGIMER, Chandigarh, and St. John's Research Institute, Bengaluru, whereas Amrita Institute of Medical Sciences, Sher-i-Kashmir Institute of Medical Sciences, J&K, and Sitaram Bhartia Institute of Science and Research, New Delhi were the most impactful. CS Yajnik, N Tandon, and V Khadilkar were the most prolific, whereas A Laxmaiah, HPS Sachdev, and V Mohan were the most impactful authors. Seven of the ten top productive journals were Indian, but only three were among the most impactful. Conclusion: India lags in CHO research behind other countries having similar current and future projections for the prevalence of CHO. Its research output, but not impact, has increased over the past two decades. India's international collaboration in CHO research is meager. Our analysis identifies the contributions of various stakeholders in addressing CHO and provides a framework for researchers, policymakers, organizations, and national government for future research to develop interventions for effective prevention and control of CHO.

Introduction: Mucormycosis is a well-researched infection worldwide. The Indian contribution to global Mucormycosis research remains unevaluated. Materials and Methods: Elsevier's Scopus database was used to retrieve Indian publications on mucormycosis during 1998-2021. The extracted data were analyzed in terms of the number of publications, citation metrics, top productive organizations and authors, research collaborations, and active journals, using appropriate bibliometric tools. Results: India produced 799 publications on mucormycosis during 1998-2021. The publications grew at 8.5% annually and 175.1% cumulatively and received on average 9.6 citations per paper (CPP). Only 8.7% of publications involved international collaboration. The most researched types of mucormycosis were pulmonary and gastrointestinal, while diabetes mellitus and diabetic ketoacidosis were the top risk factors studied. Most of the research focused on clinical studies and treatment, while genetics was the least researched aspect of mucormycosis. The top 20 of the 294 organizations and 384 authors that participated in research contributed 59.7% and 29.4% to the total national output, and 97.3% and 76.2% to total citations, respectively. The most productive organizations were PGIMER-Chandigarh, AIIMS-New Delhi, and CMC-Vellore, and the most prolific authors were A. Chakrabarti, M.R. Shivprakash, and J. Chander. Indian Journal of Otolaryngology and Head and Neck Surgery, Mycosis, and BMJ Case Reports were the high-yielding journals, whereas Medical Mycology, Mycosis, and Journal of Postgraduate Medicine were the most impactful. Conclusion: Indian research in mucormycosis has shown consistent growth during 1998-2021. There is, however, a need to improve on collaborative research and focus on emerging areas such as the genetics of mucormycosis. [ABSTRACT FROM AUTHOR]

The study focuses on the various aspects of performance of India's suicide research, such as the publication growth, citation impact, international collaboration, subject-wise distribution of publications, contribution and citation impact of Indian organizations and authors, medium of communication, and characteristics of its high-cited papers. This study reveals that India's research output on suicides research witnessed an annual average growth rate of 10.49%, registered an average citation impact per paper of 9.75, and a share of 16.23% of international collaborative publications. India's global publication and share to world suicide research was 2.47% during 1999-2014. Medicine contributed the largest publication share of 84.32%, followed by pharmacology, toxicology, and pharmaceutics and social sciences (19.94%), environment science (9.37%), biochemistry, genetics and molecular biology (8.35% share), psychology (7.05% share), neuroscience (4.36% share), economics, econometrics, and finance (2.23% share), and immunology and microbiology (1.95% share) during 2005-2014. About 294 organizations and 356 authors participated in 1078 Indian papers in suicide research, of which the top 15 most productive Indian organizations and authors together contributed 36.18% and 17.44% publications share and 49.58% and 56.06% citation share to the India's publications and citation output on suicide research during 2005-2014. This study also suggests the need for taking up of measures at population, sub-population, and individual levels to prevent suicide and suicide attempts. Suicide is a complex issue and therefore suicide prevention efforts require coordination and collaboration among multiple sectors of society. [ABSTRACT FROM AUTHOR]

Objectives: Analyses were done on the Indian publication outputs on liver disorder research during 2003-2012, on several parameters, including contribution and citation impact of the most productive countries, India's overall contribution, its growth pattern, citation impact, the share of international collaboration, identifi cation of the signifi cant participating countries in India's international collaboration, contribution and impact of different types of liver disorders, productivity and impact of leading Indian institutions and authors, and pattern of communication of Indian output in most productive journals. Materials and Methods: The Scopus Citation Database has been used to retrieve the data for 10 years (2003-2012) by searching with the keyword 'liver,' in the combined Title, Abstract, and Keywords fi eld. Results: The Indian publication's output in the liver disorder research consisted of 2380 articles during 2003-2012, which increased from 143 articles in 2003 to 378 articles in 2012, witnessing an annual average growth rate of 11.92%. The average citation impact per article registered by the Indian publications for liver disorder research was 4.68 during 2003-2012, which decreased from 6.43 during 2003-2007 to 3.71 during 2008-2012. The international collaborative share of India in the overall liver disorder research was 15.34% during 2003-2012, which increased from 12.65% during 2003-2007 to 16.84% during 2008-2012. Conclusions: Keeping in view the severity of liver disorders in India, there is a need to increase the investment in Research and Development (R and D) to bring about improvements in supportive care and a need to set up a Hepatitis Registry. Efforts must be made to develop state- and government-supported prevention and control strategies, including conducting mass awareness programs, formulation of universal guidelines for immunization, promotion of partnerships, development of an evidence-based policy, and development of programs for prevention of transmission, along with better fi nancial and social support initiatives.
