Trends in iron deficiency anemia research 2010 – 2023: a bibliometric analysis

Anemia is a health disorder marked by a reduction in hemoglobin concentration (Hb), hematocrit (Ht), and erythrocyte count. Iron deficiency anemia is marked by a reduction in hemoglobin synthesis, resulting in the production of hypochromic microcytic erythrocytes. The interest over time in the topic of iron deficiency anemia throughout the world is increasing. Many studies associated with iron deficiency anemia have been conducted by various authors and are increasing from year to year. The aim of the present review was to evaluate the literature on iron deficiency published between 2010 and 2023, with a focus on the trend in number of publications and citations, the trend of the link strength on the topic of iron deficiency anemia, and the low density of articles published from 2010 to 2023, to determine the trend and novelty of the topic of iron deficiency anemia. This review was a systematic study with the stages conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) diagram. The data on scientific publications on the topic of iron deficiency anemia were collected using dimensions.ai from 2010 to 2023. The data were subsequently analyzed with the Vosviewer program. This review resulted in the following findings. First, the number of publications and citations on the topic of iron deficiency anemia increased exponentially from year to year. Second, there were 139 items, 3 clusters, and 5579 links, with a link strength of 18253 for the topic of iron deficiency anemia. Third, the recommended study topics connected with iron deficiency anemia are topics of low density, namely clinician, pathogenesis, and biofortification. The study findings may assist the interested researchers to know the trends and novelties of studies on iron deficiency anemia, and may recommend suggestions for further research.

Thermal Treatment of Biomass: A Bibliometric Analysis—The Torrefaction Case

The aim of the paper was to summarize and discuss current research trends in biomass thermal treatment (torrefaction process). Quantitative analyses were carried out, in which the main countries, research units and scientists were indicated. The analysis showed a clear upward trend in number of publications after 2010. Most scientists on selected topics come from China, USA, Canada, South Korea, Republic of China, Poland (Web od Science—Core Collection (WoS-CC) and Scopus databases). Quantitative analysis also showed that the most relevant WoS-CC categories in the summary are: Energy Fuels, Engineering Chemical, Agricultural Engineering, Biotechnology Applied Microbiology and Thermodynamics and Scopus Subject area: Energy, Chemical Engineering, Environmental Science, Engineering and Chemistry. Thematic analysis included research topics, process parameters and raw materials used. Thematic groups were separated: torrefaction process (temp.: 150–400 °C), hydrothermal carbonization process (HTC) (temp: 120–500 °C), pyrolysis process (temp.: 200–650 °C) and gasification and co-combustion process (temp.: 350–1600 °C). In the years 2015–2019, current research topics were: new torrefaction technologies (e.g., HTC), improvement of the physico-mechanical, chemical and energetic properties of produced fuel as well as the use of torrefied biomass in the process of pyrolysis, gasification and co-combustion. The raw materials used in all types of biomass thermal treatment were: energy crops, wood from fast-growing and exotic trees, waste from the agri-food industry, sewage sludge and microalgae.

Trends in marine climate change research in the Nordic region since the first IPCC report

Oceans are exposed to anthropogenic climate change shifting marine systems toward potential instabilities. The physical, biological and social implications of such shifts can be assessed within individual scientific disciplines, but can only be fully understood by combining knowledge and expertise across disciplines. For climate change related problems these research directions have been well-established since the publication of the first IPCC report in 1990, however it is not well-documented to what extent these directions are reflected in published research. Focusing on the Nordic region, we evaluated the development of climate change related marine science by quantifying trends in number of publications, disciplinarity, and scientific focus of 1362 research articles published between 1990 and 2011. Our analysis showed a faster increase in publications within climate change related marine science than in general marine science indicating a growing prioritisation of research with a climate change focus. The composition of scientific disciplines producing climate change related publications, which initially was dominated by physical sciences, shifted toward a distribution with almost even representation of physical and biological sciences with social sciences constituting a minor constant proportion. These trends suggest that the predominantly model-based directions of the IPCC have favoured the more quantitatively oriented natural sciences rather than the qualitative traditions of social sciences. In addition, despite being an often declared prerequisite to successful climate science, we found surprisingly limited progress in implementing interdisciplinary research indicating that further initiatives nurturing scientific interactions are required.

Producción científica española en obesidad a través de PubMed (1988–2007)

Objective To analyse Spanish scientific research output related to obesity during a 20-year period from 1988 to 2007 into context with the European Union productivity Methods The bibliometric study was based on research of the MEDLINE database in PubMed. Search terms were «obesity» appearing in MeSH. Linear regression was used to estimate trends in number of publications. Results We retrieved 50,120 documents on obesity in the study period, and 1,407 were by Spanish authors (2.7% of the world production). Spain, accounting for 8.1% of scientific output in this area, was the fifth most productive country in the European Union; 932 (69.1%) of papers were published in English. The average yearly increase in publications was 15%, from 91 documents in the first five-year period to 702 in the last five-period. The most frequent specialty of first author was endocrinology (279 documents, or 22.8%), followed by physiology-nutrition-bromatology (203, or 16.6%), and biochemistry (161, or 13.2%). Journals publishing the largest numbers of papers on obesity were Medicina Clínica (83 or 6.1%), Obesity Surgery (79 or 5.8%), International Journal of Obesity (73) and Nutricion Hospitalaria (59). The most productive regions in Spain were Cataluña (338 or 24.9%), Madrid (286 or 20,6%), and Navarra (159 or 11,7%). The most productive institutions were hospitals, with 708 titles (52.1%), followed by universities, with 521 (38.5%). Conclusions Obesity research in Spain has increased over the last 20 years and accounted for a substantial proportion of European Union research in this field. Half of the papers by Spanish authors were published in international non-Spanish journals. Most of papers were carried out from hospital settings and universities.

Holography

HOLOGRAPHY IN 1970 This last year in holography has continued the hectic if somewhat unproductive pace of previous years - in terms of applications. The major journals continue to publish a wide variety of papers. The Journal of the Optical Society of America has 91 index entries, 25 of which are papers and nine letters to the editor. Well over half the entries refer to published abstracts of papers presented at meetings. Applied Optics contains approximately 100 index entries of which 49 are papers and 31 letters. In a recent paper an attempt was made to analyze this literature in a preliminary way by plotting the trends in number of publications. One plot concerned the number of indexed items in the two journals mentioned above. The trends inferred from these plots for the Journal of the Optical Society have proved to be correct as Table 1 shows.
