Bibliometric and thematic analysis of articles in the field of infertility (2011-2015)

Forty-five years of disability and rehabilitation research: review of the journal Disability and Rehabilitation through bibliometric analysis

PURPOSE

Disability and Rehabilitation has a history of 45 years. This article aims to comprehensively analyze the scientific production of this journal to celebrate and present its achievements over time.

METHODS

This study examines the performance of the journal's publications between 1978 and 2022, using indicators of bibliometric analysis and scientific mapping techniques. These techniques explore publication trends, emerging and discussed themes, institutions, countries, collaboration patterns, and citations.

RESULTS

In the journal's 45 years, 7369 documents were published, with an average annual growth rate of 15.18%, reaching 176976 citations in 7019 documents. The United Kingdom was the most productive, and the University of Toronto was the most representative (587 articles). Recurring themes were rehabilitation, stroke, and disability. The most consolidated research themes were rehabilitation, stroke, activities of daily living, and physiotherapy.

CONCLUSIONS

This study contributes to scientific development in the field of disability and rehabilitation. The findings provide data to advance the understanding of academic practices in these fields and also provide valuable insights for the strategic planning, potential innovations, and future actions of the editorial board of the journal Disability and Rehabilitation.

A 10-Year Bibliometric Analysis of Global Research on Gut Microbiota and Parkinson's Disease: Characteristics, Impact, and Trends

Objective

To perform a bibliometric analysis of scientific production related to gut microbiota and Parkinson's disease between 2011 and 2020.

Methods

A descriptive, retrospective, cross-sectional, and bibliometric study was carried out. The Scopus database was used as a source to evaluate the worldwide scientific production on intestinal microbiota and its relationship with Parkinson's disease. Data were extracted from Scopus using a formula developed with thesaurus terms MeSH (Medline) and Emtree (Embase).

Results

A total of 591 documents were found. The retrieved manuscripts received an average of 41.9 citations per document. Four of the 10 most productive authors were Italian. The University of Helsinki (Finland) was the institution with the highest scientific production (19 papers) and the highest impact (5921 citations). In terms of productivity and impact, Movement Disorders ranked first with 38 papers and 2782 citations, and those papers published in Q1 quartile journals exceeded the sum of the remaining quartiles. Papers with international collaboration were the most cited. Keyword analysis showed that the terms Parkinson Disease, Disease, and Intestine Flora were the most frequent.

Conclusion

The number of papers on Parkinson's disease and gut microbiota has been increasing; however, high-quality journals maintain the same high publication rate. International collaboration from high-income countries played an important role in the impact generated by the publications.

An In-Depth Bibliometric Analysis and Current Perspective on Male infertility Research

Purpose

Male infertility is emerging as a major, escalating global health problem that imposes the need to investigate research trends in male infertility. The purpose of this study is to analyze male infertility research trends in the past 20 years using the bibliometric database from Scopus.

Materials and Methods

In order to perform an in-depth bibliometric analysis, we propose a ‘Funnel Model’, which includes several layers representing different sub-areas of male infertility research. Adopting this Funnel Model, using Scopus, we retrieved relevant bibliometric data (articles per year, authors, affiliations, journals, and countries) for various areas of male infertility research and performed descriptive statistics.

Results

The bibliometric analysis showed an exponential increase in male infertility research in the last 20 years. USA dominated in research output, with Agarwal, A. as the most prolific researcher. Testicular cancer, obesity and metabolic syndrome, and azoospermia were found to dominate male infertility research, whereas erectile dysfunction and unexplained male infertility had lesser attention. Interestingly, prognostic/diagnostic and mechanistic studies have significantly increased in parallel over the last 20 years. Furthermore, our bibliometric analysis revealed fewer publications in proteomics, transcriptomics and metabolomics when compared to genomics. Also, an increasing trend in publication was seen in assisted reproductive technology (ART) research.

Conclusions

An integrated and steep escalation in the field of omics and ART research appears to be a prerequisite for further development of future diagnostic and therapeutic strategies for male infertility.
