Trends and hotspots of global ultra-processed food research(2010-2023):A scientometric study

Background:Recently,ultra-processed foods(UPFs)have attracted considerable attention,leading to numerous studies worldwide.Scientometrics is currently gaining popularity among scientific communities,offering advantage of providing critical references to scholars of specific fields.Methods:This scientometric study aimed to analyze trends and hotspots of UPF research using English articles or reviews related to UPFs retrieved from the Web of Science Core Collection on March 5,2023.Two independent researchers selected the identified records on titles,abstracts,and author’s keywords,and the data were analyzed using R-bibliometrix,CiteSpace,and VOSviewer.Results:A total of 1018 publications(901 articles and 117 reviews)published from 2010 to 2023 were included.The result showed a significant increase in UPF publications over the past decades.Brazil published the highest number of papers(n=473),with over half of the top 10 active institutions were located in Brazil.The University of São Paulo contributed the most publications(n=206)and the 10 most productive authors belonged to this institution,with Monteiro CA and Levy RB contributing the most publications.The main research foundations included the NOVA system,the definition of UPFs,the prevalence of UPFs,and the impact of UPFs on dietary quality and health status.The main research frontiers included topics such as“systematic review,”“NOVA food classification,”“COVID-19,”“diabetes,”“pregnancy,”“food addiction,”“warning labels,”“plant-based diet,”and“commercial determinants of health”.Conclusions:This study provided a comprehensive overview of development trends and research hotspots of global UPF studies.

Exploring the pathogenesis of idiopathic granulomatous mastitis based on the prolactin theory

Prolactin(PRL),as a cytokine,plays a variety of multidirectional roles in immunity and inflammation.An autoimmune condition known as idiopathic granulomatous mastitis(IGM)involves many inflammatory cells and cytokines.PRL links neuroendocrine and immune systems and plays an active role in the inflammatory and immune processes.Based on the theory of PRL and combined with the latest research review at home and abroad,this paper aims to review the mechanism of action of PRL on IGM from the aspects of various inflammatory cells,cytokines and pathways,revealing the influence of PRL theory on IGM and the mechanism of action,so as to effectively control inflammation in the long-term.

SnS_(2) nanosheets decorated SnO_(2) hollow multishelled nanostructures for enhanced sensing of triethylamine gas

Highly sensitive,fast and low-temperature detection of triethylamine(TEA)gas based on SnO_(2) is attractive yet remains challenging.Herein,SnS_(2) nanosheets(NSs)/SnO_(2) hollow multishelled structures(HoMSs)-based sensors are designed by the synthesis of SnO_(2) HoMSs,followed by in situ sulfuration with thioacetamide.By varying the thioacetamide levels,Sn S_(2)/SnO_(2) heterostructures with different SnS_(2) contents were obtained and their TEA gas sensing performances were investigated.
