RESUMEN
BACKGROUND: The proportion of women in medicine, especially in pediatrics, is noticeably increasing. Yet, leadership positions are predominantly occupied by men. METHODS: Academic authorships of 156,642 pediatric original research articles were analyzed with regard to gender disparities. The evaluation included the proportion of female authorships (FAP), distributions over first-, co- and last-authorships, gender-related citation rates, a productivity analysis and investigations on journals, countries and pediatric sub-disciplines. RESULTS: In all, 46.6% of all authorships in pediatric research were held by female authors. Women held relatively more first-authorships (FAP = 52%) and had higher odds for first- (OR = 1.3) and co- (OR = 1.11) authorships, compared to men. The Prestige Index of -0.13 indicated an underrepresentation of female authors at prestigious first- and last-authorships. Citation rates were not affected by the gender of the key authors. At the country-level pronounced gender-related differences were detected. The time trend showed increasing female prospects forecasting a female-dominated Prestige Index of 0.05 in 2023. CONCLUSION: The integration of women in pediatric research has advanced. Opportunities for female authors differ at the country-level, but overall women are lacking in leadership positions. Improving career opportunities for women in pediatric research can be expected in the coming years. IMPACT: There is a measurable progress in the integration of female scientists. Gender-neutrality is partially achieved in pediatric research with yet a female underrepresentation in leading positions. Our descriptive study presents gender-related dynamics in pediatric research that forecast improving career opportunities for female scientists.

BACKGROUND: The number of operations by the German emergency medical service almost doubled between 1994 and 2016. The associated expenses increased by 380% in a similar period. Operations with treatment on-site, which retrospectively proved to be misallocated (OFF-Missions), have a substantial proportion of the assignment of the emergency medical service (EMS). Besides OFF-Missions, operations with patient transport play a dominant role (named as ON-Missions). The aim of this study is to work out the medical and economic relevance of both operation types. METHODS: This analysis examined N = 819,780 missions of the EMS and patient transport service (PTS) in the catchment area of the emergency medical dispatch centre (EMDC) Bad Kreuznach over the period from 01/01/2007 to 12/31/2016 in terms of triage and disposition, urban-rural distribution, duration of operations and economic relevance (p < .01). RESULTS: 53.4% of ON-Missions are triaged with the indication non-life-threatening patient transport; however, 63.7% are processed by the devices of the EMS. Within the OFF-Mission cohort, 78.2 and 85.8% are triaged or dispatched for the EMS. 74% of all ON-Missions are located in urban areas, 26% in rural areas; 81.3% of rural operations are performed by the EMS. 66% of OFF-Missions are in cities. 93.2% of the remaining 34% of operations in rural locations are also performed by the EMS. The odds for both ON- and OFF-Missions in rural areas are significantly higher than for PTS (ORON 3.6, 95% CI 3.21-3.30; OROFF 3.18, 95% CI 3.04-3.32). OFF-Missions last 47.2 min (SD 42.3; CI 46.9-47.4), while ON-Missions are processed after 79.7 min on average (SD 47.6; CI 79.6-79.9). ON-Missions generated a turnover of more than 114 million, while OFF-Missions made a loss of almost 13 million. CONCLUSIONS: This study particularly highlights the increasing utilization of emergency devices; especially in OFF-Missions, the resources of the EMS have a higher number of operations than PTS. OFF-Missions cause immensely high costs due to misallocations from an economic point of view. Appropriate patient management appears necessary from both medical and economic perspective, which requires multiple solution approaches.

BACKGROUND: Since mammography belongs to the most important preventive techniques in modern medicine, this study maps the related worldwide research output, which encompasses quantitative and qualitative aspects of the scientific activity and socio-economic features. METHODS: The New Quality and Quantity Indices in Science (NewQIS) computing platform identified all mammography-specific articles in the Web of Science within two time periods, from 1900 to 2014 (P1) and from 2015 to 2020 (P2), a combination of density-equalizing mapping projections (DEMP) and socio-economic benchmarking was applied for analysis. RESULTS: A total of 13,629 articles were retrieved. 8,744 articles were identified in P1 and 4,885 in P2. More than 100 articles were published annually since the 1980s. Regarding productivity and collaborative efforts, the United States was the leading nation in both evaluation periods. In our socioeconomic analysis, it was also ranked at the first place in P1 [72.68 mammography-related publications per GDP/capita (RGDP)]. The US was followed by the UK and Germany in P1 and by UK and India in P2. When population sizes were related to mammography research activities, Scandinavian countries and the Netherlands showed the highest research activity in P1 (e.g., Sweden: 31.89 publications per 1 million inhabitants). Gender analysis illustrated a relative dominance of female researchers in most countries with the exception of Japan. CONCLUSIONS: The global mammography research activity over the last century is paralleled by strong international collaborative efforts and follows largely economic figures and prevalence rates but displays distinct differences in comparison to the research landscape of other biomedical entities.
RESUMEN
Objective: The purpose of this study was to examine the influence of a total knee arthroplasty (TKA) on linked cranial and caudal structures. Methods: Thirty-five (14f/21m) subjects participated in this study: 15 subjects (9f, 6m) pre- and post- TKA and a control group of 20 subjects (5f, 15m). The measurements included: jaw condyle position and movement, back scan, plantar pressure distribution, and body sway. Results: There were no significant differences in electronic position analysis of the jaw; however, the protrusion of the TKA group improved (p = 0.001). The test group had a more anteriorly inclined thoracic spine and a less pronounced lumbar lordosis. Before and after surgery, the body sway in the test group was larger. Conclusion: The TKA affected most prominently the static mechanisms of the postural control and the spine position. The trajectories of the mandible during protrusion also changed slightly.

BACKGROUND AND AIMS: Despite decades of effort, numerous aspects on ulcerative colitis (UC) remain unknown and require further investigation. Scientists experience numerous challenges to survey >40,000 items that have been published on UC since 1900, to evaluate their scientific impact or to identify collaborative networks publishing the most relevant work. Hence, no current, detailed and comprehensive knowledge regarding the worldwide research architecture of UC has been established until now. METHODS: We conducted a scientometric study employing the previously validated NewQIS (New Quality and Quantity Indices in Science) platform to quantify the global research activity in the field of UC. Hereby, the total research productivity, scientific output of countries, individual institutions, authors, journals, their collaborative networks as well as semiqualitative aspects were assessed. Results were visualized via state-of-the-art density-equalizing mapping projections. RESULTS: The United States, Germany, and the United Kingdom play leading roles regarding scientific activity, multilateral and bilateral cooperations. Within the past decades, research on UC diversified into a field covering numerous subject areas. Recently published studies predict that the scientific progress will be mainly depending on international cooperations; we can confirm that development by now. CONCLUSIONS: Scientometrics proofed to be a useful methodical approach to evaluate quantitative and semiqualitative aspects regarding UC. Also, we conclude that the influence of international cooperations on the scientific progress in the field of UC is constantly progressing.

Systematic reviews represent the core and backbone of evidence-based medicine (EBM) strategies in all fields of medicine. In order to depict a first global sketch of the international efforts in the Cochrane database systematic reviews (CDSR), we analyzed the systematic reviews of the Cochrane database. Our global maps of systematic reviewing offer intriguing structural insights into the world of EBM strategies. They demonstrate that for the CDSR, the UK and Commonwealth countries take the lead position. Since patients, care providers and health systems all over the world benefit from systematic reviewing, institutions in other countries should increase their commitment.

IMPORTANCE: Previous studies examined sex distributions in different medical faculties, especially because increasingly more women entered the medical field in recent decades. Little is known at present about the female representation in ophthalmic research. OBJECTIVE: To clarify sex equalities in ophthalmic research by evaluating the representation of female authorships. DESIGN AND SETTING: This bibliometric analysis included original English-language articles published in ophthalmologic journals indexed in the Web of Science from January 2008 to August 2018. Authorships were assigned by sex according to first name. MAIN OUTCOMES AND MEASURES: Outcomes included the proportion of female authorships, odds ratios of women holding prestigious first and last authorships compared with men (measured by the prestige index), citation rates, a productivity analysis, and cross-journal and transnational female representation within ophthalmic research. The hypothesis was formulated during data collection. RESULTS: Bibliometric data were abstracted from 87â¯640 original articles published in 248 ophthalmologic journals. Of 344â¯433 total authorships, female scholars held 34.9% (120â¯305 of 344â¯433) of all authorships, 37.1% (24â¯924 of 67â¯226) of first authorships, 36.7% (77â¯295 of 210â¯372) of coauthorships, and 27.1% (18â¯086 of 66â¯835) of last authorships. The female-to-male odds ratio was 1.12 (95% CI, 1.10-1.14) for first authorships, 1.20 (95% CI, 1.18-1.22) for coauthorships, and 0.63 (95% CI, 0.62-0.64) for last authorships, with annual growth rates of 1.6% overall, 1.6% for first authorships, 1.3% for coauthorships, and 2.5% for last authorships. Women were underrepresented in prestigious authorships (prestige index = -0.22). The underrepresentation remains almost stable for articles with many authors (prestige index = -0.17 for articles with >9 authors per article). Articles with female key authors were cited slightly less frequently (95% CI for female vs male authors, 10.8-11.0 vs 11.5-11.7 citations/articles). Women published fewer papers than men (42.5% [n = 41â¯383]; women held 34.9% [n = 120â¯207] of the authorships), show cross-journal uniformity and differences among single countries (change in prestige index = 0.66 vs 1.96). Overall, 44.1% of female authorships and a sex-neutral distribution of prestigious authorships are prognosticated for 2028. CONCLUSIONS AND RELEVANCE: This algorithm analysis suggests the integration of women into ophthalmic research is average compared with other disciplines. A sex-specific gap exists for last authorship, suggesting career inequalities. With a growing number of female researchers in ophthalmology, the number of women in senior ranks may increase in the future.
RESUMEN
BACKGROUND: Alzheimer's disease and dementia are an increasing burden affecting more than 50 million patients worldwide. Hence, research has increased significantly in recent decades. It is recognized that female authors are systematically underrepresented in research in general. OBJECTIVE: In this article, we examine gender disparities in academic research on dementia and Alzheimer's disease in the last decade. METHODS: 104,858 male and female authorships from 37,961 original research articles were analyzed. The global and country-specific distribution of women across first, co, and last authorships was determined with the inclusion of a citation and productivity analysis. RESULTS: 42.1% of all authorships and 50.2% of the first, 42.2% of the co, and 32.8% of the last authorships were held by women. Women were less commonly cited, published fewer articles and were also less likely to secure prestigious authorships in articles with multiple authors compared with men. Distinct differences were observed among the countries. CONCLUSION: Substantial growth in the number of prestigious female authorships has been observed to date and is predicted to continue in the future, with an emphasis on the progressive representation of women and a diminishing gender gap.

The presubiculum contains head direction cells that are crucial for spatial orientation. Here, we examined the connectivity and strengths of thalamic inputs to presubicular layer 3 neurons projecting to the medial entorhinal cortex in the mouse. We recorded pairs of projection neurons and interneurons while optogenetically stimulating afferent fibers from the anterior thalamic nuclei. Thalamic input differentially affects presubicular neurons: layer 3 pyramidal neurons and fast-spiking parvalbumin-expressing interneurons are directly and monosynaptically activated, with depressing dynamics, whereas somatostatin-expressing interneurons are indirectly excited, during repetitive anterior thalamic nuclei activity. This arrangement ensures that the thalamic excitation of layer 3 cells is often followed by disynaptic inhibition. Feedforward inhibition is largely mediated by parvalbumin interneurons, which have a high probability of connection to presubicular pyramidal cells, and it may enforce temporally precise head direction tuning during head turns. Our data point to the potential contribution of presubicular microcircuits for fine-tuning thalamic head direction signals transmitted to medial entorhinal cortex.SIGNIFICANCE STATEMENT How microcircuits participate in shaping neural inputs is crucial to understanding information processing in the brain. Here, we show how the presubiculum may process thalamic head directional information before transmitting it to the medial entorhinal cortex. Synaptic inputs from the anterior thalamic nuclei excite layer 3 pyramidal cells and parvalbumin interneurons, which mediate disynaptic feedforward inhibition. Somatostatin interneurons are excited indirectly. Presubicular circuits may switch between two regimens depending on the angular velocity of head movements. During immobility, somatostatin-pyramidal cell interactions could support maintained head directional firing with attractor-like dynamics. During rapid head turns, in contrast, parvalbumin-mediated feedforward inhibition may act to tune the head direction signal transmitted to medial entorhinal cortex.

BACKGROUND: The present study aims to elucidate the success concerning gender equality in cancer research in the last decade (from 2008 to 2017) with prostate cancer as the target parameter. RESULTS: 31.7% of all authorships and 36.3% of the first, 32.5% of the co- and 22.6% of the last authorships were held by women. The corresponding female-to-male odds ratio is 1.26 (CI: 1.22-1.30) for first, 1.15 (CI: 1.12-1.18) for co- and 0.59 (CI: 0.57-0.62) for last authorships. The annual growth rates are 0.6% overall and 0.9% for first, 0.2% for co-authorships, and 2.8% for last authorships. Women are slightly underrepresented at prestigious authorships compared to men. The female underrepresentation accentuates in articles with many authors that attract the highest citation rates. Multi-author articles with male key authors are more frequently cited. Men publish more articles compared to women (61.8% male authors are responsible for 68.3% of the authorships) and are overrepresented at productivity levels of more than 1 article per author. Major regional differences were found with best female odds in Sweden, Brazil, and Austria. The prognosis for the next decade forecasts a harmonization of authorship odds. CONCLUSION: Prostate cancer research is characterized by a career dichotomy with few women in academic leadership positions and many female early career researchers. This career dichotomy has been narrowed in the last decade and will likely be further reduced in the future. METHODS: On the basis of the Gendermetrics Platform, a total of 26,234 articles related to prostate cancer research were analyzed.
RESUMEN
OBJECTIVE: The study aims to elucidate the state of gender equality in high-impact medical research, analyzing the representation of female authorships from January, 2008 to September, 2017. METHODS: 133â893 male and female authorships from seven high-impact medical journals were analyzed. The key methodology was the combined analysis of the relative frequency, odds ratio and citations of female authorships. The Prestige Index measures the distribution of prestigious authorships between the two genders. RESULTS: 35.0â% of all authorships and 34.3â% of the first, 36.1â% of the co- and 24.2â% of the last authorships were held by women. Female authors have an odds ratio of 0.97 (KI: 0.93â-â1.01) for first, 1.36 (KI: 1.32â-â1.40) for co- und 0.57 (KI: 0.54â-â0.60) for last authorships compared to male authors. The proportion of female authorships exhibits an annual growth of 1.3â% overall, with 0.5â% for first, 1.2â% for co-, and 0.8â% for last authorships. Women are underrepresented at prestigious authorship compared to men (Prestige Indexâ=â-0.38). The underrepresentation accentuates in highly competitive articles attracting the highest citation rates, namely, articles with many authors and articles that were published in highest-impact journals. Multi-author articles with male key authors are more frequently cited than articles with female key authors. The gender-specific differences in citation rates increase the more authors contribute to an article. Women publish fewer articles compared to men (39.6â% female authors are responsible for 35.0â% of the authorships) and are underrepresented at productivity levels of more than 1 article per author. Distinct differences at the country level were revealed. CONCLUSION: High impact medical research is characterized by few female group leaders as last authors and many female researchers being first or co-authors early in their career. It is very likely that this gender-specific career dichotomy will persistent in the next decade.

OBJECTIVE: The present study aims to elucidate the state of gender equality in high-quality dermatological research by analysing the representation of female authorships from January 2008 to May 2017. DESIGN: Retrospective, descriptive study. SETTING: 113 189 male and female authorships from 23 373 research articles published in 23 dermatological Q1 journals were analysed with the aid of the Gendermetrics Platform. RESULTS: 43.0% of all authorships and 50.2% of the firstauthorships, 43.7% of the coauthorships and 33.1% of the last authorships are held by women. The corresponding female-to-male ORs are 1.41 (95% CI 1.37 to 1.45) for first authorships, 1.07 (95% CI 1.04 to 1.10) for coauthorships and 0.60 (95% CI 0.58 to 0.62) for last authorships. The annual growth rates are 1.74% overall and 1.45% for first authorships, 1.53% for coauthorships and 2.97% for last authorships. Women are slightly under-represented at prestigious authorships compared with men (Prestige Index=-0.11). The under-representation remains stable in highly competitive articles attracting the highest citation rates, namely, articles with many authors and articles that were published in highest-impact journals. Multiauthor articles with male key authors are only slightly more frequently cited than those with female key authors. Women publish slightly fewer papers compared with men (47.2% women hold 43.0% of the authorships). At the level of individual journals, there is a high degree of uniformity in gender-specific authorship odds. By contrast, distinct differences at country level were revealed. The prognosis for the next decades forecasts a consecutive harmonisation of authorship odds between the two genders. CONCLUSIONS: In high-quality dermatological research, the integration of female scholars is advanced as compared with other medical disciplines. A gender gap consists mainly in the form of a career dichotomy, with many female early career researchers and few women in academic leadership positions. However, this gender gap has been narrowed in the last decade and will likely be further reduced in the future.

BACKGROUND AND GOALS: Crohn's disease (CD) is an inflammatory bowel disease, which can lead to abdominal pain, weight loss, fatigue, severe diarrhea, and malnutrition. Despite enormous efforts and progress in diagnosis and therapy, there are still many aspects of uncertainty leading to an increasing scientific interest in this topic. As it is challenging to survey all articles regarding CD and to measure their scientific importance, this study uses reliable scientometric tools to evaluate the global research output on CD related to quantitative and qualitative aspects and in chronological and geographical context. STUDY: We conducted a scientometric analysis to assess all global research activity on CD from 1900 until 2013. We analyzed the research output of countries, individual institutions, journals, authors and their collaborative networks and depicted our findings by density-equalizing map projections. RESULTS: The worldwide research architecture indicated that the United States, the United Kingdom, Germany, and France play leading role regarding scientific activity, h-indices, multilateral and bilateral cooperations. There is a dramatic increase of collaborative publications since the 1990s, which underlines recent studies pronouncing that the scientific progress will be mainly depending on international cooperations. CONCLUSIONS: We conclude that the field of CD is constantly progressing, in which the influence of international cooperations on the scientific productivity is of major and growing importance. North American and Western European nations constitute the scientific leaders in the field of CD whereas developing or underdeveloped countries did not exhibit considerable research productivity.

Inhaling particulate matter (PM) in environmental tobacco smoke (ETS) endangers the health of nonsmokers. Menthol, an additive in cigarettes, attenuates respiratory irritation of tobacco smoke. It reduces perceptibility of smoke and therefore passive smokers may inhale ETS unnoticed. To investigate a possible effect of menthol on PM concentrations (PM10, PM2.5, and PM1), ETS of four mentholated cigarette brands (Elixyr Menthol, Winston Menthol, Reyno Classic, and Pall Mall Menthol Blast) with varying menthol content was analyzed. ETS was generated in a standardized way using an automatic environmental tobacco smoke emitter (AETSE), followed by laser aerosol spectrometry. This analysis shows that the tested cigarette brands, despite having different menthol concentrations, do not show differences with regard to PM emissions, with the exception of Reyno Classic, which shows an increased emission, although the menthol level ranged in the midfield. More than 90% of the emitted particles had a size smaller than or equal to 1 µm. Regardless of the menthol level, the count median diameter (CMD) and the mass median diameter (MMD) were found to be 0.3 µm and 0.5 µm, respectively. These results point out that there is no effect of menthol on PM emission and that other additives might influence the increased PM emission of Reyno Classic. IMPLICATIONS: Particulate matter (PM) in ETS endangers the health of nonsmokers and smokers. This study considers the effect of menthol, an additive in cigarettes, on PM emissions. Does menthol increase the amount of PM? Due to the exposure to secondhand smoke nearly 900,000 people die each year worldwide. The aim of the study is to measure the particle concentration (L-1), mass concentration (µg m-3), and dust mass fractions shown as PM10, PM2.5, and PM1 of five different cigarette brands, including four with different menthol concentrations and one menthol-free reference cigarette, in a well-established standardized system.

BACKGROUND: The present study aims to elucidate the state of gender equality in high-quality research by analyzing the representation of female authorships in the last decade (from 2008 to 2016). METHODS: Based on the Gendermetrics platform, 293,557 research articles from 54 journals listed in the Nature Index were considered covering the categories Life Science, Multidisciplinary, Earth & Environmental and Chemistry. The core method was the combined analysis of the proportion of female authorships and the female-to-male odds ratio for first, co- and last authorships. The distribution of prestigious authorships was measured by the Prestige Index. RESULTS: 29.8% of all authorships and 33.1% of the first, 31.8% of the co- and 18.1% of the last authorships were held by women. The corresponding female-to-male odds ratio is 1.19 (CI: 1.18-1.20) for first, 1.35 (CI: 1.34-1.36) for co- and 0.47 (CI: 0.46-0.48) for last authorships. Women are underrepresented at prestigious authorships compared to men (Prestige Index = -0.42). The underrepresentation accentuates in highly competitive articles attracting the highest citation rates, namely, articles with many authors and articles that were published in highest-impact journals. More specifically, a large negative correlation between the 5-Year-Impact-Factor of a journal and the female representation at prestigious authorships was revealed (r(52) = -.63, P < .001). Women publish fewer articles compared to men (39.0% female authors are responsible for 29.8% of all authorships) and are underrepresented at productivity levels of more than 2 articles per author. Articles with female key authors are less frequently cited than articles with male key authors. The gender-specific differences in citation rates increase the more authors contribute to an article. Distinct differences at the journal, journal category, continent and country level were revealed. The prognosis for the next decades forecast a very slow harmonization of authorships odds between the two genders.

BACKGROUND: Cancer research is critically dependent on a continuous recruitment of junior research staff that devotes its academic life not only to clinical duties but also to basic and translational research. The present study aims to elucidate the success concerning gender equality in cancer research in the last decade (from 2008 to 2016) with lung cancer as the target parameter. MATERIALS AND METHODS: On the basis of the Gendermetrics Platform, a total of 19,724 articles related to lung cancer research were analyzed. The key method was the combined analysis of the proportion of female authorships and the female-to-male odds ratio for first, co- and last authorships. The distribution of prestigious authorships was measured by the Prestige Index. RESULTS: 31.3% of all authorships and 35.2% of the first, 32.2% of the co- and 22.1% of the last authorships were held by women. The corresponding female-to-male odds ratio is 1.22 (CI: 1.18-1.27) for first, 1.19 (CI: 1.16-1.23) for co- and 0.59 (CI: 0.57-0.61) for last authorships. Women are underrepresented at prestigious authorships compared to men (Prestige Index = -0.22). The female underrepresentation accentuates in articles with many authors that attract the highest citation rates. CONCLUSIONS: While the current system promotes early career promotion of women, men still outnumber women in leadership positions. However, this male-female career dichotomy has been narrowed in the last decade and will likely be further reduced in the next decade.
RESUMEN
OBJECTIVE: The study aims to elucidate the state of gender equality in epilepsy research, analyzing the representation of female authorships from 2008 to 2016. METHODS: Gendermetrics aided in analyzing 106,282 authorships from 22,180 epilepsy-related original research articles. The key methodology was the combined analysis of the relative frequency and the odds ratio of female authorships. The Prestige Index measures the distribution of prestigious authorships between the two genders. RESULTS: The following were held by women: 39.6% of all authorships and 44.1% of the first, 41.0% of the co-, and 29.0% of the last authorships. Female authors have an odds ratio of 1.25 (95% CI 1.21-1.29) for first, 1.17 (CI 1.14-1.20) for co-, and 0.57 (CI 0.55-0.59) for last authorships. The female authorship ratios showed substantial growth in recent years, with an annual growth rate of 1.7% overall, with 2.4% for first, 1.4% for co-, and 1.9% for last authorships. Women publish fewer articles compared to men (43.8% female authors hold 39.6% of the authorships). Women are also less likely to secure prestigious authorships in articles with many authors that attract the highest citation rates. Multi-author articles with male key authors are cited slightly more frequently than articles with female key authors. Distinct differences at the country level were revealed. The prognosis for the next decade forecasts significantly increasing female odds for first authorships and only slightly higher female odds for last authorships. A female authorship ratio of 49.2% is predicted for the year 2026. SIGNIFICANCE: The integration of women in the scientific field of epilepsy is advanced. However, a dichotomy is present: Although the current system promotes early career steps, there is an apparent lack of female research leaders. This structural imbalance is expected to grow in the next decade due to the consistently high increase of female early career researchers.

Introduction Hirschsprung disease (HD) is a congenital bowel innervation disorder that involves several clinical specialties. There is an increasing interest on the topic reflected by the number of annually published items. It is therefore difficult for a single scientist to survey all published items and to gauge their scientific importance or value. Thus, tremendous efforts were made to establish sustainable parameters to evaluate scientific work within the past decades. It was the birth of scientometrics. Materials and Methods To quantify the global research activity in this field, a scientometric analysis was conducted. We analyzed the research output of countries, individual institutions, authors, and their collaborative networks by using the Web of Science database. Density-equalizing maps and network diagrams were employed as state of the art visualization techniques. Results The United States is the leading country in terms of published items (n = 685), institutions (n = 347), and cooperation (n = 112). However, although there is dominance in quantity, the most intensive international networks between authors and institutions are not linked to the United States. By contrast, most of the European countries combine the highest impact of publications. Further analysis reveal the influence of international cooperation and associated phenomena on the research field HD. Conclusion We conclude that the field of HD is constantly progressing. The importance of international cooperation in the scientific community is continuously growing.
