ABSTRACT
BACKGROUND: Since the consensus of ISAPP on the definition of the term "postbiotic" there has been an enthusiasm for publications in review form-their number being disproportionate to the primary research. The aim of this bibliometry is to analyze the bibliometric trends of this newfound interest in the field. METHODS: Search of the PubMed database for review articles on postbiotics, published between November 2021 and June 2024. RESULTS: Analysis was performed on 92 review articles, the number corresponding to 2.9 reviews per month. China, Poland, Italy, Iran and India had the maximum productivity among the 32 countries involved; 21 articles were published in 13 journals with the highest impact factor, while 45 were in 16 journals with an IF between 4.0 and 4.9. The authors were mainly affiliated to universities with specialization in both basic research and technology, as well as food science. The top five publications regarding the citations received, published in Foods (2), EBioMedicine, Biomolecules, and Front. Nutr., have collected between 138 and 109 citations. CONCLUSIONS: The ever-growing number of reviews regarding postbiotics is perhaps disproportionate to the actual original research in the field. Further clinical trials would extend and deepen the subject and facilitate the drowning of more robust conclusions in relation to their effects.

BACKGROUND: Bibliometric analysis is an effective method for measuring scientific contributions in a variety of fields. It enables the numerical analysis of publications in a specific field and period of time, as well as the relationships between these publications. The present bibliometric analysis of publications relating to obesity treatment by means of intragastric balloons aimed to identify the bariatric centers using intragastric balloons, through the publications relating to their productivity; and furthermore, to reveal collaborations, types of balloons used, number of patients involved, and authors' productivity and favored journals. METHOD: The PubMed and Scopus databases were used to retrieve only original articles presenting the results in body weight reduction. RESULTS: Bibliographic research identified 164 publications for the period 2000-2021. Italy was ranked first with 37 publications; USA participated as collaborator with 9 different countries; the fluid-filled Orbera balloon is featured in 126 publications; the journal Obesity Surgery hosted 86 publications; Brazil reported the greatest number of patients with 5874 cases; Lorenzo M and Genco A, co-authors from Italy, authored 14 and 12 publications, respectively, and the most cited article was that of Genco et al. [2007] with 441 citations. CONCLUSIONS: Bibliometric analysis gave us the opportunity to identify the centers through their scientific publications and to classify them in relation to their productivity in articles, in collaborations, in number of cases reported, and in the number of citations gained.
