The evolution of public attention in acute kidney injury and continuous renal replacement therapy: trends analysis from 2004 to 2024.

Acute kidney injury (AKI) and the need for Continuous Renal Replacement Therapy (CRRT) are critically important health concerns. This study analyzes global and regional Internet search queries to understand public attention in AKI and CRRT over time. We used Google Trends™ to analyze search queries for AKI and CRRT from January 2004 to March 2024. The study examined global trends and detailed insights from the United States, including state-by-state breakdowns. We identified patterns, peaks of attention, and temporal trends in public attention, comparing regional variations across the US and top-ranking countries worldwide. Global attention in AKI peaked in October 2022, with Portugal, Zambia, and Spain showing the highest regional attention. Within the United States, peak attention was in February 2008. Tennessee, Pennsylvania, and West Virginia were the top states that paid attention to AKI. Attention in CRRT peaked globally in March 2024. South Korea, Saudi Arabia, and Bahrain have led the global attention to CRRT. In the United States, peak attention was in April 2020. West Virginia, Tennessee, and Kentucky showed the highest state-specific attention in CRRT. This study reveals significant temporal and geographical variations in online search patterns for AKI and CRRT, suggesting evolving public attention to these critical health issues. This knowledge can guide the development of targeted public health initiatives, enhance medical education efforts, and help healthcare systems tailor their approach to improving awareness and outcomes in kidney health across diverse populations.

Spatial Assessment of the Digital Economy at the National and Sub-National Level

The study examines the concept of the digital economy, highlights the challenges in measuring it, and explores the development of indexes as a tool for assessing its growth and the effectiveness of policies and strategies. The proposed index is suitable for both national and sub-national spatial assessments, and it was tested and validated using examples from regions in Russia and European countries. The selected indicators comprehensively capture the geographical distribution of digital economic activity, including the concentration of digital businesses in specific regions, the availability of high-speed internet and mobile networks, the distribution of ICT-related jobs across different regions, and the level of e-commerce activity. The authors initiated an analysis and comparison of available data sources, which resulted in a list of indicators that allows for a sufficient assessment of the levels of digital economy development. The resulting index was used to assess the digital economy’s development in regions in Russia and European countries. The top-ranking countries were Scandinavian, while Moscow dominated the rankings among Russian regions. The results also highlighted significant disparities in the development of the digital economy within Russia and Europe. The study’s findings align with those of other international and domestic studies, confirming the reliability of the proposed methodology.

Формування інноваційного потенціалу підприємств в умовах цифрової економіки

The article analyzes the features of formation of innovative potential of enterprises under conditions determined by the transition from industrial-market to information-network economy, which combine different regularities and mixed forms, have signs of emerging digitalization of traditional business processes, application of innovative tools for production, support and development of business. The signs of economic models of development today are digitalization (integration of digital technologies into business processes), inclusion (taking into account the social factor), circularity (use of high technologies for the production of alternative types of energy, environmental protection). The results of scientific and technological progress provide companies and project teams with strategic opportunities to respond quickly to market demands, create innovative products, ensure flexibility and uniqueness of decision-making and, thus, predetermine the appearance of new business systems and business processes, create a new value essence of innovative products and services (for example, Uber, Airbnb, digital banking, etc.). The carried out analysis of conditions, status and prospects of innovative development of the world-wide leading companies and of their experience provided an opportunity to highlight the best practices of the top-ranking countries in the field of industrial innovations and priority directions for improving traditional management techniques and methods, to identify relevant strategizing tools for the integration of domestic enterprises into the international business environment.

Regional well-being inequalities arising from healthcare expenditure public policies in Spain.

Well-being inequalities arising from different healthcare expenditure public policies is currently a hot topic at a national scale, but especially so at a sub-national level because the inequalities in question are among citizens of the same country. Spain is an optimal study area to carry out research on this topic because it is considered to have one of the best health systems in the world, it is one of the top-ranking countries in terms of life expectancy rates (the indicators we use for well-being), and it has a decentralized public health system with significantly different regional healthcare expenditure public policies. Given that the factors involved in the complex direct, indirect, and second-order relationships between well-being and health spending are latent in nature, and that there are more hypotheses than certainties regarding these relationships, we propose a partial least squares structural equation modeling specification to test the research hypotheses and to estimate the corresponding impacts. These constructs are proxied by a set of 26 indicators, for which annual values at a regional scale were used for the period 2005–2018. From the estimation of this model, it can be concluded that mortality, expenditure and resources are the factors that have the greatest impact on well-being. In addition, a cluster analysis of the indicators for the constructs included in this research reveals the existence of three clearly differentiated groups of autonomous communities: the northern part of the country plus Extremadura (characterized by the lowest well-being and the highest mortality rates), Madrid (with the best results in well-being and mortality, the lowest public health expenditure per inhabitant and percentage of pharmaceutical spending, and the highest percentage in specialty care services and medical staff spending), and the rest of the country (south-eastern regions, with similar well-being values to those of the first group but with less health expenditure). Finally, a principal component analysis reveals that “healthiness” and “basic spending” are the optimal factors for mapping well-being and health spending in Spain.

Open innovation in SMEs a bibliometric literature review using VOSviewer

Purpose – The focus of this study is to evaluate the features of open innovation using data accessed from the Scopus online database. We are looking at two keywords: open innovation and SMEs. Design/methodology/approach – The study measured a bibliometric analysis of 1,214 articles from 157 journals during 2007-2020. Findings: The findings showed that the publication trend on open innovation kept increasing. The most cited article was Open Innovation in SMEs: Trends, Motives, and Management Challenges by Van de Vrande with 1,107 citations, followed by Lee et al. with 699 citations. The publication journal with the highest citation was Technovation and Research Policy. The United Kingdom and Italy were in the top-ranking countries for publications on this topic. The document citation category showed that Belgium ranked the highest with 1,990, followed by the Netherland with 1,212. Research limitation/implications: This study provides a literature search on open innovation and has several limitations that require future study recognition. These limitations include that databases are limited to sources originating from one database only in data collection and data synthesis. Practical implications: The practical implications provide benefits about open innovation, which can help SMEs understand open innovation and apply it as their preferred strategy in developing business. This study also allows SMEs owners and managers to understand open innovation as a strategic choice to consider as the concept is a part of the strategic intervention for their business. Originality/value: This study provides the most influential contribution and impact on the research interest of open innovation that develops from various fields, including leading researchers and their home countries. Second, a co-citation analysis addressed the second question in this research study.

Global and Chinese publications in plastic surgery journals between 2010 and 2020: a bibliometric analysis.

BackgroundPlastic surgery has evolved rapidly in recent years. We performed a bibliometric analysis of plastic surgery publications from 2010 to 2020 to evaluate global developments in plastic surgery and the Chinese contribution to this field.MethodsThe 2020 Journal Citation Reports (JCR) was used to identify all plastic surgery journals; those that were available on the Web of Science database were retrieved and analyzed according to their number of published articles, citation rates, impact factors (IFs), research funding, and article references. We also determined the most popular journals for research from the 8 top-ranking countries in terms of contributed articles, including China.ResultsFrom 2010 to 2020, 55,554 articles were published in the 35 selected plastic surgery journals. China, which contributed 9.48% of these articles, was the country with the second-highest number of articles published, a number which has been increasing annually. The average IF of Chinese articles was 1.74, with an average citation count of 6.68. These figures were significantly lower than those for articles from developed countries. China contributed 1,641 articles to the 10 highest impact plastic surgery journals. The Journal of Craniofacial Surgery was the most popular in terms of contributions by China. China had the highest rate of articles supported by funding (45.30%). The top 12 research-topic clusters were obtained by analyzing the references in the articles. Emerging research-topic trends worldwide and in China included fat grafting and blindness after filler injection.ConclusionsFrom 2010 to 2020, research into plastic surgery increased continuously, both worldwide and in China. However, the quality of the Chinese articles was lower than that of other top-ranked countries. Researchers who have elected to conduct research might consider emerging trends when designing future studies.

Background and purposeThe magnitude of the coronavirus disease 2019 (COVID-19) pandemic on the healthcare system, economy, education, and social networking is dreadful, the least to say. Surprisingly, and unlike previous epidemics, the impact has been universal, and even top-ranking countries with solid economies were not immune. The purpose of this study is to develop a better understanding of the Saudi community's response and reaction to the preventative measures implemented by the government to combat the COVID-19 pandemic.MethodologyA cross-sectional study using a self-administered online-based questionnaire was conducted among 920 participants from March 2020 to February 2021 among the Saudi community across the Kingdom.ResultsAmong the studied participants, the majority (60%) are always committed to washing their hands according to the Ministry of Health (MoH) instructions, and 74% indicated that they were always compliant with the sneezing etiquette outlined by the MoH. Studied participants were affected through different influencers of life aspects. Moreover, 63% of them gained new skills and behaviors during the pandemic curfew. Additionally, many studied participants assumed that "life will not return to what it used to be" as a future perception.ConclusionIn conclusion, the present findings proved the importance and power of the Saudi Vision (2030) represented by the National Transformation Program on enhancing the healthcare system, facilitating access to healthcare, and integrating technology among government parties addressed during the COVID-19 pandemic.

Global scientific research progress in mycetoma: a bibliometric analysis

Mycetoma is a neglected tropical disease that attracts little attention in regard to research and publications and hence this study was undertaken to determine the trends and global scientific research output in mycetoma-related fields. Mycetoma data were retrieved from the Web of Science (WoS) and Scopus databases. The MeSH Browser was used to extract relevant keywords. Biblioshiny software (R-studio cloud), VOSviewer v. 1.6.6 and SPSS software were used for data management. Research trends on mycetoma increased globally from 1999 to 2020. The results were 404 documents (4444 citations) in WoS and 513 documents (5709 citations) in Scopus, and the average number of citations per article was 11 in WoS and 11.13 in Scopus. There was a significant association between the total number of citations and the total citations per year in both WoS (r=0.833, p<0.0001) and Scopus (r=0.926, p<0.0001). Sudan, India, the Netherlands and Mexico were the top-ranking productive countries for mycetoma publications in WoS, while India, the USA and Mexico were the top-ranking countries in Scopus. Articles on mycetoma were mainly published in PLoS Neglected Tropical Diseases, the International Journal of Dermatology and the Journal of Clinical Microbiology. A. H. Fahal from the Mycetoma Research Centre, University of Khartoum, Sudan, had the highest number of citations in mycetoma research during 1999-2020, followed by W. W. J. van de Sande from the Erasmus Medical Centre, University of Rotterdam, the Netherlands, during 2003-2020. The analysis provides insight into a global overview of Mycetoma research. In addition, the analysis holds a better understanding of the development trends that have emerged in Mycetoma over the past 21 years, which can also offer a scientific reference for future research.

The study aimed to discuss Arab Gulf states in the global competitiveness index issued annually by the World Economic Forum during the period (2010- 2018) in terms of the economic efficiency index, and the efficiency factor of higher education and training economics. That is for the hypothesis claimed that there is an effect of the efficiency of higher education and training economics in Arab Gulf states on the economic efficiency considering global competitiveness index standards. The study analyzed the situation of each of Arab Gulf states (Saudi Arabia- Kuwait- United Arab Emirates- Oman- Bahrain- Qatar) in terms of the overall rate and ranking, and used first- degree mathematical equations with one, two and three variable to reach the result of the situation of Arab Gulf states regards the top-ranking countries and the backward ranking countries, whether in the economic efficiency or in the efficiency factor of higher education and training economics. The study used a mathematical equation to analyze the effect of the efficiency factor of higher education and training economics in Arab Gulf states on the economic efficiency, and came out with several results based on mathematical equations and economic aspects with regard to the efficiency factor of higher education and training economics in Arab Gulf states. The study found that the degree of impact of the efficiency factor of higher education and training economics on the economic efficiency in Arab Gulf states in light of global competitiveness index standards are considered medium to tend to rise, reaching (11.20%) out of (17%).

Contrasts in alcohol-related mortality in Czechia and Lithuania: Analysis of time trends and educational differences.

Introduction and Aims. Globally, Czechia and Lithuania are among the top‐ranking countries in terms of high alcohol consumption. This study highlights notable contrasts in temporal trends in alcohol‐related mortality and identifies country‐specific patterns in educational differences. Design and Methods. The study uses harmonised cause‐of‐death series from the Human Cause of Death Database. Mortality disparities by education were assessed using census‐linked mortality data. Directly standardised death rates were used to estimate levels of national and group‐specific mortality. Relative and absolute mortality differences by education were assessed by range‐type measures (Poisson regression mortality ratios and rate differences) and Gini‐type measures. Results. Between 1994–1995 and 2016, the absolute difference between Czechia and Lithuania in terms of alcohol‐related age‐standardised death rates (per 1 000 000) decreased from 450 for males and 130 for females to 76 in males and 11 in females. In both countries, alcohol‐related mortality was markedly higher among persons of lower education levels. Lithuanian males experienced the highest absolute inequalities measured by rate difference between the low and high educated (740 per million), while Lithuanian females showed the most pronounced relative inequalities (6.70‐fold difference between low and high educated). The corresponding figures were less than half for Czechia. Discussion and Conclusions. Reducing educational disparities in alcohol‐related mortality within both countries would have a substantial impact on overall levels. Policies aimed at targeting the lowest priced and illegal alcohols and reducing levels of harmful drinking should be a priority, especially in Lithuania.

Societal Integration in Countries Ranking Similarly in Ease of Doing Business Index

Countries across the world differ in terms of macro-environmental factors. These differences reflect in their performance as well as growth and development. Most efficient countries have some common characteristics that make them distinct as compared to less efficient countries. Every year World Bank ranks countries on Ease of doing business Index. The present paper is an attempt to see if like other macro environmental factors (per capita income corruption etc.), there is any pattern in culture/social dimensions as well in two different groups of countries, i.e. countries which are ranked high and those which are ranked low on Ease of Doing Business Index. The data is taken from World Bank’s website. Top and bottom ranking countries were analyzed as two separate groups on two different parameters from Hofstede’s cultural dimension framework, viz., Individualistic vs. Collectivist and Power Distance.

Rhodiola rosea: A Quantitative and Qualitative Assessment of Global Publications Output during 2003-18

A quantitative and qualitative assessment of global research output (2016) on the “Rhodiola rosea” plant based on select bibliometric indicators, using Scopus database covering period 1993-2018, is presented here. Analyzed data on a series of bibliometric measures, like average annual growth, citations per paper, international collaborative papers, relative citation index, activity index, top productive countries, organizations, authors, journals and highly cited papers. The global publications registered an annual average growth rate of 12.97% and its citation impact averaged to 17.59 citations per paper. China and USA together account for more than 36% share of global output on Rhodiola rosea, whereas other 8 top ranking countries accounted each for global share between 4.06% and 7.60% during 2003-18. 83.04% global publication share and 89.95% global citation share has been contributed by top 10 countries during 2003-18. Sweden (2.78), Canada (1.17) and USA (1.11) registered the highest relative citation index among top 10 countries during 2003-81. Swedish Herbal Institute, Askloster, Sweden (21 papers), Medical University of Warsaw, Poland (14 papers), Corvinus University of Budapest, Hungary were the three the most productive organizations and Z. Gyorgy and A. Panossian (18 papers each) and G. Wikman (14 papers) were the three top most productive authors. Phytomedicine (25 papers), Phytotherapy Research (21 papers) and Evidence-based Complementary and Alternate Medicine (15 papers) were the three leading journals contributing research in this area.

The enigma of franchising in China

PurposeAlthough China is among the most populated and fastest growing markets in the world, the reason why China’s franchising scale and scope is so limited remains an enigma. The purpose of this paper is to shed light on franchising in China and offer strategies for practitioners to more effectively operate under a franchise model in the Chinese market.Design/methodology/approachThis paper reviews both literature and practical sources providing some primary data from interviews conducted with franchise industry practitioners in China.FindingsThe findings of this paper are that foreign entrants to China must carefully consider if they should enter the Chinese market through franchising or if the market may be too difficult to navigate. Franchisors, whose brand is unknown in China or have operations that are too Western-centric, should probably seek international markets closer to home. Those with a high value proposition in the local market and the capabilities to adapt effectively to China’s peculiarities may, however, find a promising and profitable niche to operate in.Originality/valueThis paper focuses on the under examined realities of franchising in the Chinese market. Based on the previous experiences of franchisors in China, the paper raises seven practical strategies that practitioners can use to more successfully enter the Chinese market through franchising. Although China is among the most populated and fastest growing markets in the world, the reason why China’s franchising scale and scope is so limited remains an enigma. According to the International Franchise Association and International Trade Administration reports, China is among the top-ranking countries in terms of trade opportunities, with the top 100 franchisor sales estimated at ¥428bn (about US$66bn). China is the largest franchise market in the world, with over 4,500 franchise systems and some 400,000 franchised outlets in over 70 industries. However, considering China’s US$13.6tn (2018) economy, this is still far lower than its full potential. In addition, the scope of franchising is limited and is mostly centered in food and beverage and retail outlets, which consists of approximately 40 per cent of all franchisors.

Bibliometric analysis of scientific publications in rheumatology journals from China and other top-ranking countries between 2007 and 2017.

ObjectivesRheumatology-related diseases remain a significant burden worldwide. However, little is known about the comparative status of rheumatology research between Mainland China (MC) and the world’s leading countries. The aim of this study is to compare the quantity and quality of research output in the field of rheumatology that were written by researchers from MC, the USA, the UK, the Netherlands and France.MethodsBetween 2007 and 2017, all articles published in 30 rheumatology journals were identified via Science Citation Index Expanded database. The number of total and annual articles, article types (randomized controlled trials (RCTs), reviews, case reports, clinical trials and meta-analysis), impact factor (IF), citations, h-index and articles in the high-impact journals were collected for quantity and quality comparisons. The correlation of socioeconomic factors and annual publications was also analyzed.ResultsFrom 2007 to 2017, there were 53,439 articles published in rheumatology journals, of which researchers from the USA published 13,391 articles, followed by the UK, the Netherlands, France and MC with 6,179, 4,310, 4,066 and 2,898 articles, respectively. Publications from MC represented the ninth, but the number is growing rapidly. For total and average citations, MC still lags behind the other four countries in the study. Similar trends were observed in average IF, h-index and articles in the high-impact journals. In terms of article types, the USA occupies the dominant place, except for meta-analysis. The annual numbers of articles from MC and the USA were positively correlated with gross domestic product (p < 0.05).ConclusionsThe USA has played predominant role in rheumatology research for the last 11 years. The annual number of published articles from MC has increased notably from 2007 to 2017. Although MC has made progress in the number of published articles over the past decade, it still lags far behind the highly developed countries in most bibliometric indicators. Thus, the general quality of publications from MC needs further improvement.

Scientific publication in obstetrics and gynecology from Mainland China and other top-ranking countries: A 10-year survey of the literature.

To evaluate the output of scientific publications in obstetrics and gynecology journals from Mainland China and six other countries, to compare the difference of research situation between Mainland China and the developed countries in order to measure the trend of number of publication in the field of Obstetrics and Gynecology. Information on article amounts, impact factors (IF), citation and publication in high-impact obstetrics and gynecology journals by seven top-ranking countries between January 1, 2007 and August 31, 2017, was extracted from Web of Science databases. A total of 137 661 articles were published between 2007 and 2017 in the 98 obstetrics and gynecology journals. The cumulative IF and citations of articles from USA were the highest. The highest average citation was France and Mainland China ranked fourth. There were 52 631 papers published in the top 10 obstetrics and gynecology journals and the USA accounted for the majority of these papers (33 978, 64.6%), followed by England (8347, 15.9%). Articles from the USA were most often published in American Journal of Obstetrics and Gynecology (10658) and those from Mainland China were mostly published in Fertility and Sterility (809). The USA published the most articles having high IF, making the greatest contribution to the field of obstetrics and gynecology. Although the number of scientific publications from Mainland China has rapidly increased from 2007 to 2017, the quality of these publications has not been as satisfactory. It implys that Chinese current academic evaluation system should pay special attention to the quality of academic papers, instead of the number of papers published by scientists.

Mapping diabetes research in Middle Eastern countries during 2007-2013: A scientometric analysis

Background: Scientometric studies are highly important, as they provide information about scientific products worldwide and empower scientists to compare research activities in different regions. The present study was conducted to map scientific research in diabetes mellitus using scientometric analysis in Middle Eastern countries during 2003- 2007. Methods: This was an analytical study with a scientometric approach. The study population was formed by the indexed scientific results of diabetes mellitus in the Web of Science database during 2007-2013. Data were analyzed using Excel, and HistCite to map the scientific texts. Results: A total of 6532 records were retrieved from 3926 institutions. These records belonged to 19 323 authors and were published in 1420 journals. The Journal of Diabetes Care, with 3928 citations, had the most global citation score (GCS). The Journal of Diabetes Research and Clinical Practice, with 185 citations, achieved the first degree of local citation score (LCS). Most of the scientific documents produced in the Middle East belonged to Turkey (31.91%) and Iran (21.7%). Seven scientific clusters based on LCS, and 5 based on GCS existed in the scientific mapping. Topical clusters based on global and local indices showed that the prevalence of diabetes, hyperglycemia, and pregnancy outcomes, diabetic risk factors, diabetic complications and their new treatments, and glucose monitoring in Type 1 diabetes were the fields being addressed in the main articles of the clusters. Conclusion: Scientific production and local and global citations in diabetes research in Iran (21.7% of diabetes research in the Middle East) have elevated the country to a prominent position. Top ranking countries in diabetic research were Turkey, Iran, and Israel, respectively. Moreover, this paper quantified the studies that were done on different aspects of diabetes. The results of this study can be used by health care providers to employ the best multidisciplinary approach for managing diabetes and its complications. Also, the results can help the policy-makers and governments to determine the priorities for budget allocation based on the burden of diseases. Establishing a regional diabetes network in the Middle East can be beneficial and lead to scientific collaboration and an increase in scientific production in this field.

Stature, bodyweight, BMI, dominant and non-dominant hand visual and auditory reaction time values of the participants were detected. At the end of the study, it was determined that there were statistically significant differences between the countries in terms of male dominant and non-dominant hand visual reaction values, and male dominant hand auditory reaction values. It was also determined that there were statistically significant differences between the countries in terms of female bodyweight, BMI, dominant and non-dominant hand visual reaction values, and female non-dominant hand auditory reaction values. There was statistically significant difference between female and male players with regards to dominant and non-dominant hand visual, and non-dominant hand auditory reaction values. In conclusion, it was determined that the reaction times of the top ranking countries in the fifth International Rumi Child Sport Games under-15 were at a better level, and it can be concluded that this factor played an important role for success alongside with technique and tactic features.

Scientific research output in orthopaedics from China and other top-ranking countries: a 10-year survey of the literature.

ObjectivesOrthopaedics-related diseases and conditions are a significant burden worldwide. In this study, we aimed to compare the quantity and quality of research output in the field of orthopaedics from Mainland China (MC), USA, UK, Japan and Germany.SettingThe USA, UK, Japan, Germany and MC.ParticipantsWe selected orthopaedics journals from the subject category ‘orthopedics’ from the Science Citation Index Expanded (SCIE).Outcome measuresThe number of publications, the number of publications in the surveyed publication types, impact factor (IF) and citations from the corresponding country from 2005 to 2014 were collected for quantity and quality comparisons.ResultsA total of 128 895 articles were published worldwide in orthopaedics-related journals from 2005 to 2014. The USA contributed the largest proportion (31 190 (24.20%)), followed by the UK (6703 (5.20%)), Japan (5718 (4.41%)), Germany (4701 (3.66%)) and MC (3389 (2.63%)). Publications from MC represented the fewest, but this quantity is rapidly increasing. The quantity of annual publications from MC has exceeded that of Germany since 2012. The USA plays a predominant role in all kinds of publication types under investigation in the study, except in the category of meta-analysis. MC was in the last place for cumulative IFs, and the average IF actually decreased from the beginning of the study. For total and average citations, MC still lags behind the other countries in the study.ConclusionsThe USA has occupied the dominant place in orthopaedics-related research for the last 10 years. Although MC has made great progress in the number of published works in the field of orthopaedics over the last 10 years, the quality of these publishing efforts needs further improvement.

Teachers’ perceptions of the quantity and quality of professional development activities in Turkey

AbstractProfessional development for teachers has been a substantial issue in contemporary educational research and policy. Yet, opportunities for professional development activities have been very limited in Turkey. In this study, we examined Turkish teachers’ involvement in professional development activities by comparing their participation with the level of participation in top-performing countries in the Trends in International Mathematics and Science Study 2011, including Singapore, South Korea, Hong Kong, Taiwan, and Japan. Then, we also conducted face-to-face interviews with 13 Turkish mathematics and science teachers in order to explore their views about the current professional development opportunities for teachers in Turkey. The results of this study indicate that, when compared with teachers from Turkey, a larger proportion of teachers in the top-ranking countries participated in professional development activities in most of the sub-categories of professional development in both mathematics ...
