Background: The spread of ticks has also led to the emergence of regional, previously unknown tick-borne diseases (TBDs) that pose an immediate threat to public health systems worldwide. People who spend time or work outdoors are at risk without closer awareness of regional exposures. That is especially true for tourists, who very easily come into contact with ticks and get bitten while hiking and climbing. A regional lack of surveillance, lack of awareness, lack of scientific background, and misdiagnosis makes it hard to assess the actual threat properly., Methods: Therefore, this bibliometric study aims to assess the global research on ticks and some TBDs. Geographical and temporal patterns are elaborated under epidemiological and socioeconomic aspects. That will provide a factual basis for targeted action at the scientific, societal, and policy levels against the growing threat associated with ticks., Results: The USA and Brazil can be identified as the key players in tick research, followed by Russia and some Central European countries. The socioeconomic analysis points to epidemiologically relevant regions, as also shown by comparison with the TBD analysis. A correlation between countries' gross domestic product and publication performance was found. Lack of scientific resources limits the necessary research and surveillance programs., Conclusions: Many regions that are popular travel destinations are threatened by new tick species and thus new health risks. Therefore, outdoor activities in many locations may pose an unknown hazard that requires regionally differentiated scientific investigation and better, globally networked research strategies., Competing Interests: Declaration of competing interest The authors have declared no conflicts of interest., (Copyright © 2022 Elsevier Ltd.

Objectives: Inadequate oral hygiene still leads to many serious diseases all over the world. Therefore, this study aimed to analyze scientific research in the field of oral health in order to be able to comprehend their relevant subject areas, research connections, or developments. Methods : This study shows the actual key players of research on oral hygiene in high-income economies with only marginal participation from lower economies. This still corresponds to the current burden situations, but they are more and more shifting to the disadvantage of the low-income countries. There is a clear North-South and West-East gradient, with the USA and the Western European nations being the most publishing nations on oral hygiene. As an emerging country, Brazil plays a role in the research. Results : This study shows the actual key players of research on oral hygiene in high-income economies with only marginal participation from lower economies. This still corresponds to the current burden situations, but they are more and more shifting to the disadvantage of the low-income countries. There is a clear North-South and West-East gradient, with the USA and the Western European nations being the most publishing nations on oral hygiene. As an emerging country, Brazil plays a role in the research. Conclusions : The scientific power players were concentrated in high-income countries. However, the changing epidemiological situation requires a different scientific approach to oral hygiene. This requires an expansion of the international network to meet the demands of future global oral health burdens, which are mainly related to oral hygiene.

Obstructive Sleep Apnea is emerging as a global health epidemic, particularly due to the obesity pandemic. However, comprehensive prevalence data are still lacking and global OSA research has not yet been structurally evaluated. Using the latest comprehensive age/gender-specific BMI and obesity data, a global landscape estimating the risk/burden of OSA was created. Results were presented in relation to an in-depth analysis of OSA research and countries' socioeconomic/scientific background. While the USA, Canada, and Japan are the highest publishing countries on OSA, Iceland, Greece, and Israel appeared at the forefront when relating the scientific output to socioeconomic parameters. Conversely, China, India, and Russia showed relatively low performances in these relations. Analysis of the estimated population at risk (EPR) of OSA showed the USA, China, India, and Brazil as the leading countries. Although the EPR and OSA research correlated strongly, major regional discrepancies between the estimated demand and actual research performances were identified, mainly in, but not limited to, developing nations. Our study highlights regional challenges/imbalances in the global activity on OSA and allows targeted measures to mitigate the burden of undiagnosed/untreated OSA. Furthermore, the inclusion of disadvantaged countries in international collaborations could stimulate local research efforts and provide valuable insights into the regional epidemiology of OSA.
