Primary Care for Gestational Diabetes: A Bibliometric Analysis of Publications from 1991 to 2024

Gestational diabetes mellitus (GDM) represents a significant medical complication during pregnancy, with a global prevalence ranging from 2% to 26% and increasing by over 30% in recent decades. Therefore, the aim of our study is to assess the trends and distribution of published studies, as well as the contributions of countries, institutions, journals, and authors to the development of primary care for pregnant women with gestational diabetes. In this bibliometric analysis, we examine the role of primary health care in GDM from 1991 to 2024. The data were sourced from Scopus and Web of Science, encompassing 276 articles from 150 sources and involving 1375 authors. The analysis reveals a steady increase in publications, with a 4.29% annual growth rate. This study identifies the USA and UK as leading countries in GDM research, and there are significant international collaborations, with the USA having 17 joint articles with other countries. The University of Eastern Finland, Ohio State University, and Harvard University are noted as the most prolific institutions, with 23, 17, and 16 articles, respectively. Additionally, the journal Diabetes Care published the highest number of articles, totaling 635. Prominent authors such as Bernstein J. and McCloskey L., with seven articles each, have made substantial contributions to the field. Our work highlights the need to pay special attention to primary care for gestational diabetes, as many negative consequences of the disease can be prevented at this stage. Innovative approaches to screening for GDM can significantly improve treatment outcomes and reduce health risks, which will have long-term positive effects both for individual patients and society as a whole.

Blowin' in the Wind: Mapping the Dispersion of Metal(loid)s From Atacama Mining

The Atacama Desert's naturally elevated metal(loid)s pose a unique challenge for assessing the environmental impact of mining, particularly for indigenous communities residing in these areas. This study investigates how copper mining influences the dispersion of these elements in the wind-transportable fraction (<75 μm) of surface sediments across an 80 km radius. We employed a multi-pronged approach, utilizing spatial modeling to map element distributions, exponential decay analysis to quantify concentration decline with distance, regime shift modeling to identify dispersion pattern variations, and pollution assessment to evaluate impact. Our results reveal significant mining-driven increases in surface concentrations of copper (Cu), molybdenum (Mo), and arsenic (As). Notably, within the first 20 km, concentrations peaked at 1,016 mg kg⁻1 for Cu, 31 mg kg⁻1 for Mo, and a remarkable 165 mg kg⁻1 for As. Cu and Mo displayed significant dispersion, extending up to 50 km from the source. However, As exhibited the most extensive reach, traveling up to 70 km downwind, highlighting the far-reaching ecological footprint of mining operations. Mineralogical analyses corroborated these findings, identifying mining-related minerals in surface sediments far beyond the immediate mining area. Although pollution indices based on the proposed Local Geochemical Background reveal significant contamination across the study area, establishing accurate pre-industrial baseline values is essential for a more reliable assessment. This study challenges the concept of "natural pollution" by demonstrating that human activities exacerbate baseline metal(loid)s levels. Expanding monitoring protocols is imperative to comprehensively assess the combined effects of multiple emission sources, including mining and natural processes, in safeguarding environmental and human health for future generations.

Do research collaborations age like wine? Absolute and relative measures of CANZUK research partnerships' strength since the 1950s

Although previous studies of today's globalised and competitive research landscape have mentioned the research collaborations of CANZUK countries (i.e., Australia, Canada, New Zealand, and the United Kingdom), none have yet studied them in detail. Further, such studies have used different measures of international research collaboration (IRC), resulting in disparate findings. This paper, therefore, analyses the strengths of CANZUK research collaborations, how those collaborations have changed over time, and assesses the effect of three ways of measures on the results (absolute strength, bilateral similarity, and multilateral similarity). We provide a detailed characterisation of the CANZUK research network and its relationships with partner countries, which reveals that the most collaborative CANZUK countries are the UK and Australia, among other findings. We also confirm that many findings differ depending on which measures are used. We offer an explanation of this difference with reference to the nature of the measures (i.e., what they really measure) and make suggestions for suitable measures in future studies depending on their purpose. Finally, we discuss how this study's findings can be used by research policy makers (in CANZUK and elsewhere) in deciding on research strategy and by researchers in appropriately measuring IRC.

The field of mRNA vaccines has witnessed rapid development in recent years, leading to significant changes in global scientific collaboration. In this study, a bibliometric and social network analysis was conducted to reveal the evolution of global scientific collaboration in mRNA vaccine research. Altogether 6974 articles published since 2010 were retrieved and categorized into Period 1 (2010-2019), Period 2 (2020-2021) and Period 3 (2022-2023). During Period 2 and 3, there was a significant rise in the proportion of publications involving domestic inter-institutional cooperation (42.0%, 54.0% and 59.1%, respectively in Period 1, 2, and 3), while a significant decrease in international cooperation (32.1%, 23.7% and 21.0%). More countries participated in international collaboration during Period 2 and 3, with the US, the UK and Germany remaining top three throughout all periods, while some other countries like Italy, Japan, and China experiencing significant shifts. Significant correlations between collaboration type and publication impact and between geographical distance and collaborative publication counts were detected. Furthermore, significant changes in research focuses and institutions that are major contributors in the mRNA vaccine development have been observed. In conclusion, the mRNA vaccine field has experienced rapid development over the past decade, with significant evolutions of global scientific collaboration detected in our study.

Research Topic Specialization of Universities in Information Science and Library Science and Its Impact on Inter-University Collaboration

Universities significantly empower the development of science and technology, and inter-university research collaborations have been one of the major approaches. Considering each university has its expertise regarding research topics in a given discipline, the present paper examines the specialization of university research and its impact on inter-university collaborations. Based on a keyword network constructed via research articles in Information Science and Library Science, 10 research topics are identified. Accordingly, the research topic diversity of a university and the research topic similarity between two universities are quantified. The universities with diverse research topics are found to be more collaborative. A further collaboration network analysis based on the Quadradic Assignment Procedure reveals the important role of research topic similarity on the closeness and impact of collaborations. The different research topic specializations largely prevent close collaborations between two universities, but on the other hand, have the potential to form a complementary combination of knowledge leading to more impactful research output. The analysis and results highlight the important role of research topic specialization and provide insights for the university- or department-level strategy for research collaborations.
