Schizophrenia research in India: A scientometric assessmentof India's publications during 1990-2019

Global trends in diabetic eye disease research from 2012 to 2021

JOURNAL/nrgr/04.03/01300535-202410000-00032/figure1/v/2024-02-06T055622Z/r/image-tiff Diabetic eye disease refers to a group of eye complications that occur in diabetic patients and include diabetic retinopathy, diabetic macular edema, diabetic cataracts, and diabetic glaucoma. However, the global epidemiology of these conditions has not been well characterized. In this study, we collected information on diabetic eye disease-related research grants from seven representative countries--the United States, China, Japan, the United Kingdom, Spain, Germany, and France--by searching for all global diabetic eye disease journal articles in the Web of Science and PubMed databases, all global registered clinical trials in the ClinicalTrials database, and new drugs approved by the United States, China, Japan, and EU agencies from 2012 to 2021. During this time period, diabetic retinopathy accounted for the vast majority (89.53%) of the 2288 government research grants that were funded to investigate diabetic eye disease, followed by diabetic macular edema (9.27%). The United States granted the most research funding for diabetic eye disease out of the seven countries assessed. The research objectives of grants focusing on diabetic retinopathy and diabetic macular edema differed by country. Additionally, the United States was dominant in terms of research output, publishing 17.53% of global papers about diabetic eye disease and receiving 22.58% of total citations. The United States and the United Kingdom led international collaborations in research into diabetic eye disease. Of the 415 clinical trials that we identified, diabetic macular edema was the major disease that was targeted for drug development (58.19%). Approximately half of the trials (49.13%) pertained to angiogenesis. However, few drugs were approved for ophthalmic (40 out of 1830; 2.19%) and diabetic eye disease (3 out of 1830; 0.02%) applications. Our findings show that basic and translational research related to diabetic eye disease in the past decade has not been highly active, and has yielded few new treatment methods and newly approved drugs.

Clozapine research from India: A systematic review

BACKGROUND

Although clozapine is much researched in western literature, a review on Indian research on clozapine published in 2010 reported limited data and need for further research in this area.

AIM

We aimed to conduct a systematic review of research on clozapine from India from 2010 to mid-2022 and also compare the same with research output before 2010.

METHODOLOGY

A systematic various search engines, i.e., PUBMED, Medknow, Hinari and Google Scholar was done using the key words clozapine and India. Published articles with clozapine in the title and having an author from India, published during 2010 to July 2022 were included.

RESULTS

Initial Internet and hand searches yielded 280 articles, out of which 126 articles were excluded due to various reasons and 154 articles, were included for the review. This included 84 case reports, 49 original articles, 11 review articles and 10 letters to the editor as comments. We found an increase in the number of publications during the period of 2010-2022 compared to 1997-2009 in all types of publications. Over the years a significant proportion of the articles focused on various side effects of clozapine, factors associated with response and non-response to clozapine and evaluation of outcomes other than efficacy/effectiveness. However, all the studies were limited to a single centre with no multicentric studies on clozapine.

CONCLUSION

Over the last 12 years or so, there is increase in the number of publications on clozapine. However, there is lack of multicentric studies.

Global research on Obsessive Compulsive Disorder and related disorders: A scientometric assessment of global research during 2002-2021

OBJECTIVES

to examine the global publication output on Obsessive Compulsive Disorder (OCD) during the last 20 years using bibliometric methods.

METHODS

The quantitative and qualitative analysis of global publications was performed for all the publications in Scopus database by using "OCD, Obsessive Compulsive Disorder, other related disorders" as keyword in "Title" tag.

RESULTS

10,365 publications on OCD and related disorders were indexed in Scopus international database in the last 20 years and these publications were cited 241,962 times, averaging 23.34 citations per paper (CPP). About 24.91% share of global publication output received funding support and registered a CPP of 36.57. Among various countries, authors from USA, U.K., and Germany contributed the largest number of publications (3585, 965, and 836 publications), and publications arising from Netherlands (36.79 and 1.58), U.K. (32.65 and 1.40), and USA (32.43 and 1.39) registered the highest CPP and relative citation index (RCI). The organizations that produced the highest number of publications were Harvard Medical School, USA (487 papers), Massachusetts General Hospital, USA (454 papers), and King's College London, U.K. (297 papers). The authors who published highest number of papers were E.A. Storch (254 papers), D. Mataix-Cols (178 papers), and D.J. Stein (178 papers). The authors whose publications had highest CPP and RCI were B.D. Greenberg (USA) (73.76 and 3.16), and S.A. Rasmussen (USA) (63.36 and 2.71).

CONCLUSIONS

This study reveals that majority of the research on OCD and related disorders is from the developed countries and compared to disorders like schizophrenia, OCD has received less research attention.

A Bibliometric Analysis of Dhat Syndrome

Dhat syndrome is a culture-bound syndrome, mostly prevailed in South East Asia that has been systematically defined approximately six decades ago. Assessment of the published literature would help to identify the research density as well as the gaps. We aim to do a bibliometric analysis of published global scientific literature on dhat syndrome. The Scopus database was systematically searched by using the keywords “Dhat syndrome”, “Semen loss syndrome”, “Semen loss anxiety” from inception to 11th August 2021. A total of 89 articles on dhat syndrome were found in the Scopus database. Most of the articles were from India and were published in the Indian Journal of Psychiatry and Asian Journal of Psychiatry. The majority (>58%) of research on dhat syndrome was published in the last decade. The PGIMER (Chandigarh), AIIMS (New Delhi) & KGMU (Lucknow) are the leading institutes in dhat syndrome research. The year 2004 had the highest number of total citations (n = 135), while the year 1975 had the highest number of citations per article (60 citations per article). This bibliometric review identified that despite dhat syndrome is a common condition in the South East Asian countries, research on the condition is limited.
