The valuation of neuroblastoma research heterogeneity at African country level is unspecified. Therefore, the study assesses the heterogeneity of neuroblastoma research in 54 African countries and develops recommendations for national cancer-control plans. Metadata of peer-reviewed scientific publications allied to African neuroblastoma research were retrieved from the Web of Science™ Core Collection Database for bibliometric analysis. Comprehensive science mapping analysis and statistical analyses were performed with bibliometric online platform2 and GraphPad Prism v. 10.2.3. This study revealed that African countries focused the neuroblastoma research publications mainly on the sustainable development goal of good health and well-being. The dominating research area in Africa is oncology followed by pharmacology. Only 26 of 54 African countries were accountable for total neuroblastoma research in Africa, with South Africa and Egypt contributing 61% of the whole continent’s neuroblastoma research. Egypt, South Africa, Tunisia, Morocco, and Nigeria are the five most active African countries, and they are funded by different funding agencies internationally and domestically. The collected analysed data of this study draws special attention to heterogeneity and enduring upward correlating trajectory of Africa’s neuroblastoma publication numbers, their citations, acquired funds, and countries’ cooperation. Furthermore, this heterogeneity finding flags the necessity of developing a comprehensive strategic plan and implementation to cultivate neuroblastoma research as a fundamental part of each African country’s national cancer control plans.

Objectives: To characterize the bibliometric characteristics of the global scientific production of original research on gasless laparoscopy in the Web of Science Core Collection (WoSCC) platform. Materials and methods: A bibliometric study of original articles published up to the year 2023 was carried out. Articles were included following the selection criteria in the Rayyan web application, indexed in the Scopus database. The bibliometric analysis was performed using the Bibliometrix program in the R programming language and VOSviewer. The bibliometric characteristics evaluated were articles, journals, citations, publications, ten most mentioned articles, journals with the highest number of publications, authors and institutional affiliations; and cooccurrence of terms. Results: A total of 223 publications were included, with the highest number of articles being published in the years 1999 and 2014. The publication with the most citations was found to be a randomized trial by Galizia G in 2001 with 132 citations. We identified 846 authors involved in the production of articles on gasless laparoscopy, with Nakamura H being the most productive author with 15 articles between the years 2007 and 2020, followed by Takeda A and Imoto S, all three affiliated with “Gifu Prefectural Tajimi Hospital”. The country with the highest production was Japan with 64 publications, followed by China and Italy with 46 and 18 publications, respectively. In the top 10 journals with the highest number of publications, “Surgical Endoscopy—Ultrasound and Interventional Techniques” is in first place with 20 articles published on gasless laparoscopy; in addition, most of these are located in Q1 and Q2. Regarding the terms or keywords, it was found that the initial studies had terms related to the disadvantages of pneumoperitoneum and later focused on more specific topics of the application of gasless laparoscopy. Conclusions: Production on gasless laparoscopy has stagnated, with the topics of interest currently being its application in new, less invasive techniques. The most productive countries are found in the Asian and European continents, with little information collected in Latin America. This fact makes it necessary to increase the production of studies to promote this technique and its possible advantages.

Recent years have seen the publication of numerous papers on the application of three-dimensional (3D) printing in plastic surgery. Despite this growing interest, a comprehensive bibliometric analysis of the field has yet to be conducted. To address this gap, we undertook a bibliometric study to map out the knowledge structure and identify research hotspots related to 3D printing in plastic surgery. We analyzed publications from 1995 to 2024, found in the Web of Science Core Collection (WoSCC), utilizing tools such as VOSviewer, CiteSpace, and the R package “bibliometrix”. Our analysis included 1,057 documents contributed by 5,545 authors from 1,620 organizations across 71 regions, and these were published in 400 journals. We observed a steady growth in annual publications, with Europe, Asia, North America, and Oceania leading in research output. Notably, Shanghai Jiao Tong University emerged as a primary research institution in this domain. The Journal of Craniofacial Surgery and Journal of Oral and Maxillofacial Surgery have made significant contributions to the field, with Thieringer, Florian M being the most prolific and frequently cited author. Key areas of focus include medical education and surgical procedures, with “3D printing”, “virtual surgical planning” and “reconstructive/orthognathic surgery” highlighted as future research hotspots. Our study provides a detailed bibliometric analysis, revealing the evolution and progress of 3D printing technologies in plastic surgery. As these technologies continue to advance, their impact on clinical practice and patient lives is expected to be profound.
