In this research, all the scientific publications of the Iran University of Medical Sciences (IUMS) from 1980 to 2020 are studied using bibliometric analysis and scientific network visualization. This research applied quantitative research using bibliometrics and visualization of scientific publications. The research population included all the scientific publications of IUSM on the Web of Science Core Collection (WOSCC) from 1980 to 2020. Data from the WOSCC were extracted via the advanced search by searching the Iran University of Medical Sciences in the affiliation field. Microsoft Excel and VOSviewer were used for data analysis. First, the frequency distribution of the scientific publications was identified. Then, the level of international collaborations was analyzed. Finally, the citation clusters of researchers' scientific publications and keyword co-occurrence were examined. IUMS had 9950 documents indexed in the WOSCC.  Malekzadeh jointly ranked first as the most prolific author. The Iranian Red Crescent Medical Journal, with 207 articles, has the highest number of articles. All highly-cited papers were published in high-level Q1 journals. The highest collaboration rate at a national level was with the Tehran University of Medical Sciences. Internationally, IUMS's researchers had the highest collaboration with authors from the United States, the United Kingdom, Canada, and Australia, respectively. Term clustering demonstrated five main clusters: pharmacological studies, epidemiological studies, general & and internal medicine, meta-analysis and systematic review, and Immunological studies. The methods and techniques of bibliometrics and visualization are optimal for depicting and analyzing the scientific status of researchers, publications, journals, universities, countries, and even the world. The current study can be a model for analyzing bibliometric indices of other universities and research institutes in Iran and elsewhere.

This study aims to perform a bibliometric analysis of documents published in the field of Public Administration during the years 1923-2020. In this bibliometric study, all Web of Science (WOS) databases were used to retrieve the publications in this field. Using a proper search strategy, 93093 records were retrieved in the WOS database from 1923 to 2020. Excel and VOSviewer software were used for bibliometric analysis and visualization of documents. The findings show that 64.31% of documents (59860 documents) were articles; most documents were published in the Public Administration Review-Journal (n= 9011). The United States (with 31930 documents), ENGLAND (with 14636 documents), and Canada (with 7104 documents) published the most documents in this field, respectively. The University of Birmingham was the most productive institution (n=1,441, 1.54 %). Meier, K. J. S was the most productive author (n= 119, 0.12%). Keywords with the highest frequency were "management", "governance", "government", "policy", "performance", "politics", "state", and "organizations". The most co-occurrence keywords existed within three clusters, the first including keywords related to policy issues, the second including author keywords about management and performance, and the third including keywords related to state and local management. The global trend of publications in the field of Public Administration has been upward, from 54 documents in 1923 to 4561 documents in 2020. This study not only presents a full view of global Public Administration research but also can contribute to future research in this field and bibliometric studies.

Urology and nephrology are the main sub-categories of internal medicine, and relevant research had been grown in recent years.  The present study aimed to analyze the Iranian scientific publications in urology and nephrology indexed in the Science Citation Index Expanded (SCIE) from 1900 to 2020.

 This cross-sectional and scientometric study was conducted in 2021. The urology and nephrology records were extracted from the Web of Science Core Collection (WSCC) with a time limitation from 1900 to 2020. Data analysis was performed in the Excel software in terms of descriptive statistics, and the scientific maps were visualized in VOSviewer.

 Until 2020, 3439 urology and nephrology scientific publications by Iranian researchers were indexed in the SCIE. These articles had received 25393 citations in total, with an h-index of 55. More than half of the articles (56.12%) were original, and the majority were published in 2012 (345; 10.03%). Tehran University of Medical Sciences was the most productive and top-cited organization on urology and nephrology, with 914 (26.57%) documents and total citations of 7741. Kajbafzadeh (140; 4.07%) and Basiri (133; 3.86%) were the most productive authors. The most productive journals were the Iranian Journal of Kidney Disease (650; 18.90%) and the Urology Journal (386; 11.22%).

 The results demonstrated increasing of Iranian scientific publications, citations, co-authorship, and international collaboration. While the authors published their articles in higher ranking journals, more significant research budgets and open scientific diplomacy are necessary to promote visibility and motivate international collaboration among Iranian researchers.

 This analysis aimed to investigate the global research output in Iron Deficiency Anemia from a bibliometric perspective.

All 29,789 publications in IDA indexed in Scopus from 1934-2019 were included. Using MeSH-assigned keyword search, this research analyzed and visualized the bibliometric data, including annual publication trends and languages and publications, as well as active and influential authors, research institutes, countries, and journals. The scientific visualization was done by co-authorship, co-citation, and word co-occurrence techniques in VOSviewer.

The trend in IDA annual publication growth was increasing. Publications were in over 40 languages, with English as the predominant one. The majority of publications were original research. The highest scientific collaboration was between the USA and UK. Seven out of 13 top authors were from the USA. The top high influential journals were the Lancet, New England Journal of Medicine and Blood, respectively. Highly-frequent keywords were in two clusters: epidemiology and IDA management, iron metabolism, and Iron Deficiency Anemia pathophysiology.

The increasing trend of publication growth in IDA demonstrates the importance of research on it and being as an international concern. IDA needs to be investigated from many perspectives, with the main contributions of developing countries where the disease has its causes and consequences. More prolific and highly-cited journals in Iron Deficiency Anemia are of prestigious and known journals that can potentially widen the reach of publications and increase their readability and citation rates. Research on Iron Deficiency Anemia has found its way, and many topics have been considered.
