The Mediterranean diet (MD), a widely recognized healthy dietary pattern, has demonstrated significant value in the prevention and management of metabolic syndrome (MetS). However, quantitative integrated analyses of its mechanisms of action remain scarce, highlighting an urgent need for systematic collation. This study retrieved relevant literature published between 2015 and 2025 from the Web of Science and Scopus databases, and conducted visual bibliometric analyses using R software (Bibliometrix package), VOSviewer, and CiteSpace. A total of 1723 valid articles were identified from the Web of Science, and 1061 from Scopus. The number of publications steadily increased from 2015 to 2022, with a particularly notable growth spurt between 2016 and 2018, followed by a slight decline from 2022 to 2024. Spain led significantly in the number of publications, followed by Italy, the United States, and Iran, and Spain has established an extensive international cooperation network. At the journal level, Nutrients serves as the core academic platform in this field, ranking first in both publication volume and citation frequency. Current research hotspots primarily focus on the regulatory effects of MD on blood glucose homeostasis, insulin sensitivity, lipid metabolism, and blood pressure in MetS patients, as well as the mechanisms by which bioactive components (e.g., polyphenols, unsaturated fatty acids, and vitamins) promote metabolic health through anti-inflammatory, antioxidant, and insulin-sensitizing pathways. Gut microbiota modulation has evolved into an emerging research direction in this domain. Over the past decade, interdisciplinary research on MD and MetS has gained increasing attention and is expected to become a core focus in the non-pharmacological intervention of MetS. This study systematically clarifies the research status, hot topics, and developmental context of this field, providing important references for future precision nutrition mechanism research and clinical intervention trials.

Debris flow, widely viewed by geo-scientists as a special combination of landslide and flash flood, causes devastating damages to people and environment in northern mountainous regions of Vietnam. Field observations in the areas damaged by debris flows in northern Vietnam identified types of soils and rocks that were more likely to cause debris flows. Unlike flash floods, almost debris flows occurred at the end of the rainy season when soils and rocks were water-oversaturated thus mechanically weak; this is when pore water pressure decreases, lowering the strength from the soil. Landslides causing debris flows are commonly current slides. The tip of a landslide is often confined within a stream that has a permanent or seasonal flow. Debris flows mainly occur in proluvium, colluvial deposits or tectonic breccia zones. However, not a debris flow initiated in a tectonic breccia zone has been recorded in the northern mountainous regions of Vietnam. Colluvial deposits have been intensively investigated by many researchers worldwide. These deposits are commonly formed in neo-tectonic active zones, weak bed rocks, particularly old metamorphic rocks such as sericite shale, terrigenous and Cenozoic or late Mesozoic volcanic sedimentary rocks that are distributed at steep slopes and/or highly differentiated reliefs. These features appear to be a prerequisite for the exogenous processes, including rolling stones, falling rocks, landslides and surface erosions to occur. To study the mechanical and physical properties of colluvial deposits, the most practical approach is conducting experiments with large-sized samples or on-site experiments. However, this approach is expensive and not always favorable. Applying the rock mechanical theory, it is possible to examine C, j values if values of geological characteristics of rock blocks are known. Thus, the present study attempts clarify the cause-feedback relationship between the change of geological environment and geological hazard in general, and debris flows, in particular, providing a basic scientific insight for studying and predicting debris flows.ReferencesBauziene L., 2000.

Rare flash floods and debris flows in southern Germany

Irisin is a peptide secreted by skeletal muscle following physical exercise that is being widely studied since its discovery over the last decade. Although a robust number of studies have advanced on understanding of the effects of this myokine as an endocrine molecule and a potential candidate for therapeutic intervention for many disorders, there is no bibliometric data cataloguing the main advances regarding this myokine and generating guidelines for future directions. Objective: The aim of this study was to analyse the scientific production of biomedical journals on the myokine Irisin effects by a bibliometric analysis. Methods: A search was conducted in the Web of Science and Scopus databases using the keyword “Irisin'' to identify studies between 2001 and 2020. The data from all publications were exported and analysed on the Bibliometrix package using R software. Results: A total of 1579 papers were included, and the trend of annual publications showed a remarkable growth between 2012-2020. China and the Harvard Medical School (United States of America, USA) were the most productive countries and institutions in the Irisin research field, and the USA was the country with most cited manuscripts regarding Irisin. The current research hotspots of Irisin are in “metabolic diseases,” and “central nervous system-related diseases”. Conclusion: The authors summarize that Irisin is becoming frontier and focus on the health topics following the exercise adaptations in the upcoming years, which are worthy of further exploitation.

ObjectiveTo conduct bibliometric and visual analysis in the field of Mediterranean diet (MD) on brain health from 2005 to 2025.MethodsRelevant literature published between 2005 and 2025 was retrieved from the Web of Science and Scopus databases. R software and VOSviewer were used for data analysis and visualization.ResultsThe number of publications in this field showed a steady annual increase. The United States ranked first in terms of publication output, followed by Italy, Spain, China, and Australia. Notably, the United States also played a prominent role in international collaboration, with institutions such as Harvard University and the University of Barcelona actively cooperating with research centers worldwide.

Growing global attention to this dietary pattern highlights its potential to become a core research direction in dietary interventions for brain disorders. This study provides a comprehensive analysis of the current research landscape and key hotspots of MD on brain health, offering valuable references for future investigations.

Cancer poses a major global health challenge, and immunotherapy, known as the third revolution in cancer treatment, has brought new hope to patients. The emerging field of immunometabolism has further enhanced the safety and efficacy of immunotherapy. Over the past two decades, this field has rapidly evolved in oncology, leading to numerous significant findings. This review systematically examines the literature on immunometabolism in cancer, visualizing research trends and identifying future directions. A comprehensive literature search was conducted in the Web of Science, PubMed, and Scopus databases, covering publications from January 2000 to December 2023. We employed tools like Citespace, VOSviewer, and RStudio for visual analysis of publication trends, regional contributions, institutions, authors, journals, and keywords. A total of 3320 articles were published by 8090 authors across 1738 institutions, involving 71 countries. Leading contributors were China (n=469), the United States (n=361), and Germany (n=82). Harvard University was the most influential institution, while Frontiers in Immunology had the highest number of publications. The top research areas included glucose, lipid, and amino acid metabolism, the tumor microenvironment, and immune cell regulation. International collaboration and interdisciplinary efforts are advancing the field of cancer immunometabolism. Future research will likely focus on the interplay between metabolism and immunity, metabolic markers, immune cell reprogramming, and tumor-immune metabolic competition.

In today's dynamic and competitive environment, universities play a key role in generating, transmitting, and applying knowledge and innovation. The growing interest in evaluating university performance at national and international levels has led to developing and applying university maturity models as effective assessment tools. This article aims to present various approaches to modelling university maturity. A bibliometric analysis was based on publications in the Web of Science and Scopus databases. The research query included TITLE-ABS-KEY ("maturity model" and universit*) for Scopus and TS = ("maturity model" and universit*) for the Web of Sciences database. A total of 123 publication records were analysed. Materials published between 1994 and 2024 in English were examined. A total of 123 publications were selected for the final analysis. Based on the literature review, key factors that may influence university maturity across nine areas were identified. A theoretical University Maturity Model (UMM) is also presented, which should undergo expert evaluation in subsequent stages. Findings suggest that the application of maturity models can significantly enhance universities' management and operational efficiency, offering valuable insights for policymakers in formulating educational policies.

A detailed analysis is made of the current ideas concerning floods of a special type. We examine short-lasting torrential flash floods, one of the most widespread and hazardous natural phenomena in the world characterized by a high rate of development, and by a short duration. It is established that such floods are in a primitive stage of study, which is testified by the fact that there is no general consensus as to what should be treated as a flash flood. It is pointed out that a special term designating them is also absent in many countries. It is determined that the key formation conditions for flash floods include intense short-lasting cloudbursts, the occurrence of a river basin in mountainous regions and a small drainage area; on this basis, it is suggested that they be termed flash floods. It is shown that such floods are of the most widespread occurrence in the northern hemisphere in regions with a temperate and subtropical climate. We suggest the scheme of natural factors for formation of flash floods and their differences from debris flows and floods of other types. It is determined that the main problems of investigating the formation mechanisms and forecasting the aforementioned floods are associated with the small spatiotemporal scale of these phenomena.

In recent years, disasters caused by flash floods with many casualties have occurred frequently in China. In order to effectively prevent flash flood disasters, the State Council approved the National Flash Flood Control Planning (NFFCP) in 2006. In this planning, non-structural measures are recommended as the first step to be adopted in the prevention of flash floods, debris flow and landslide disasters caused by heavy rainfall. In order to effectively build up a comprehensive non-structural measure system for flash flood disaster prevention, the Ministry of Water Resources has asked the local authorities to conduct studies in 103 pilot counties aiming to explore practical schemes. Based on the experience from these pilot counties, the construction of non-structural measures on flash flood disaster prevention for 1836 counties was officially initiated in 2010. The contents of non-structural measures for flash flood disaster prevention at county level include eight aspects. This paper will systematically illustrate the main contents of this national project for the construction of non-structural measures for flash flood disaster prevention in China. This work could provide a reference for other countries and regions in terms of flash flood prevention.

The rapid development of digital technologies, digital transformation, business innovation, and the emergence of such technologies as artificial intelligence, blockchain, the Internet of Things provides significant potential for transforming business processes and creating new innovative models. The trend analysis conducted in this article (using the Google Trends tool) around the world for 2009-2023 showed that public interest in “business innovation” was almost constant until 2021 (according to the GT Scale, it ranged from 0.25 to 0.5). After 2021, it increased (according to the GT Scale, it was more than 0.5). At the same time, public interest in “digital transformation” has significantly increased since 2014, reaching almost maximum values in 2020-2023 (0.75 – 1.00 on the GT Scale). This confirms a growing need in society to acquire new knowledge related to the ability of businesses to adapt to digital transformation, including through creating innovative developments. Unlike trend analysis, bibliometric and comparative analyses identify trends in developing interest in this topic not among ordinary citizens – users of the Google search platform ‒ but among scientists who publish the results of their research either in monographs or in authoritative peer-reviewed scientific journals indexed by leading scientometric databases. The comparative analysis conducted in the article using the Google Books Ngram Viewer (Google) tool, which displays the frequency of references to relevant terms in English-language books for 2009-2019 worldwide, showed similar trends: the persistence of scholars’ attention to business innovation, while their interest in digital transformation is growing: in 2009-2013 – a slight increase, in 2013-2019 ‒ a significant increase. In the bibliometric analysis, a five-level mechanism for limiting the research sample was applied: only English-language and most recent (for 2018-2022) scientific articles indexed by the Scopus database in the subject area of Business, Management and Accounting were subject to analysis. Based on these limitations, the research sample for the keyword “digital transformation” was reduced from 12131 to 1700 papers, and for “business innovation” from 865 to 70. The analysis of the published articles, their views and citations, carried out using the SciVal tool, fully confirmed the conclusions drawn from the trend and comparative analysis results. In terms of digital transformation, the leaders in terms of the number of papers and the number of views are Germany, Italy, the UK and the US; in terms of citations – the UK, Germany, the US, and in terms of individual scientists – Brazil and Germany. As for the topic of business innovation, the United States is the undisputed leader in all these parameters, followed by China and the United Kingdom. Some scientists from Germany and Spain also attract the attention of the academic community (in terms of views and citations). Changes in trends and research priorities in each of the studied topics were identified and described using SciVal (analysis of the reference dynamics to the top 50 keywords in articles for 2018-2023). For example, in 2023, compared to 2022, scientific interest in issues related to “value creation” (+61.5%), “incumbents” (+66.7%), “service economy” (+83.3%), “digital marketing” (+75.0%), and “design thinking” (+150.0%) increased the most. VOSviewer software made it possible to cluster the scientific work by thematic areas. The largest cluster on digital transformation relates this concept to small and medium-sized businesses and technologies, and the largest cluster on business innovation relates it to the development of small and medium-sized enterprises and the protection of property rights.

Temporal evolution of measured and simulated infiltration following wildfire in the Colorado Front Range, USA: Shifting thresholds of runoff generation and hydrologic hazards

Objective: This research aimed to carry out a bibliographical survey through bibliometrics to know the state of the art on the anaerobic treatment of leachate from composting with nanoparticles. Theoretical Framework: Composting is one kind of waste treatment and its process generates an effluent named leachate. The anaerobic digestion can treat this material and generating biogas for energy use. Additionally, the use of nanoparticles appears as a technological tool capable of improving the production of biogas and the percentage of methane. Method: The tool used to produce this research was bibliometric analysis. Searches were performed in the Web of Science and Scopus databases in September 2024 with a focus on anaerobic digestion of compost leachate. No search period was defined. The strategy of using both databases was to expand the amount of work related to the topic. Results and Discussion: The first work indexed in both databases is from 2011. From 2011 to September 2024, 32 articles related to the topic were published with the participation of 18 countries, 153 authors and 70 institutions. The journal that accumulated the highest number of publications was Waste Management. Research Implications: The implication of this research is to provide general information about the researches being developed and thus to identify scientific gaps. From this overview, the research field can be better studied and new publications will emerge. Originality/Value: This research showed that the study of anaerobic digestion of composting leachate with nanoparticles is quite incipient and promising, as few articles on the subject have been reported. This is a scientific gap.
