Objectives: Our aim was to assess articles published in the field of radiology, nuclear medicine, and medical imaging in 2020, analyzing the linkage of radiology-related topics with coronavirus disease 2019 (COVID-19) through literature mapping, along with a bibliometric analysis for publications. Methods: We performed a search on Web of Science Core Collection database for articles in the field of radiology, nuclear medicine, and medical imaging published in 2020. We analyzed the included articles using VOS viewer software, where we analyzed the co-occurrence of keywords, which represents major topics discussed. Of the resulting topics, literature map created, and linkage analysis done. Results: A total of 24,748 articles were published in the field of radiology, nuclear medicine, and medical imaging in 2020. We found a total of 61,267 keywords, only 78 keywords occurred more than 250 times. COVID-19 had 449 occurrences, 29 links, with a total link strength of 271. MRI was the topic most commonly appearing in 2020 radiology publications, while “computed tomography” has the highest linkage strength with COVID-19, with a linkage strength of 149, representing 54.98% of the total COVID-19 linkage strength, followed by “radiotherapy, and “deep and machine learning”. The top cited paper had a total of 1,687 citations. Nine out of the 10 most cited articles discussed COVID-19 and included “COVID-19” or “coronavirus” in their title, including the top cited paper. Conclusion: While MRI was the topic that dominated, CT had the highest linkage strength with COVID-19 and represent the topic of top cited articles in 2020 radiology publications.

The Relationship

The involvement of governments and public institutions in entrepreneurial activity has grown considerably in the last years. Public governance has begun to pay more attention to the fact that, in order to achieve the goal of economic development in a country, it is necessary to increase entrepreneurship both qualitatively and quantitatively. Most governments have created significant actions that encouraged and supported the entrepreneurial activity and also they have contributed to supporting the private sector in the economy. The present paper analyses the scientific works related to entrepreneurship and public governance, as well as to investigate the connection between these topics. The study presents a bibliometric analysis of the importance of the nexus public governance and entrepreneurship. The proposed research studies 201 references collected from the Clarivate Analytics, Web of Science Core Collection database. The research methodology performed to graphically map the literature is bibliometric analysis. The analysis is carried out on three distinct levels, namely the analysis of the co-occurrence of keywords, co-citation and co-author by means of (VOS) viewer program. This approach allows us to highlight the main results presented in journals, magazines, documents, subjects, authors, institutions but also results recorded at the country level. The study also evidence the main trends and impact of research in the form of a visual and schematic research framework on the relationship between public governance and entrepreneurship and its related elements, namely innovation and development.

Introduction : Le syndrome d’apnées obstructives du sommeil (SAOS) est une affection très répandue et insuffisamment diagnostiquée, ce qui en fait un problème majeur de santé publique et de sécurité. La rééducation myofonctionnelle orofaciale (RMO) a été montrée efficace dans le traitement multidisciplinaire des SAOS de l’enfant, de l’adolescent et de l’adulte et elle est prescrite à plusieurs étapes de ces prises en charge. Objectifs : L’objectif principal de cette revue systématique de la littérature était d’évaluer l’efficacité de la rééducation myofonctionnelle orofaciale (RMO), active ou passive, dans le traitement du syndrome d’apnées obstructives du sommeil chez les enfants, les adolescents et les adultes. Matériel et méthodes : La revue systématique de la littérature fut entreprise à partir des trois bases de données électroniques : Medline (via PubMed),Cochrane Library, Web of Science Core Collection, et complétée par une recherche limitée de la littérature grise (Google Scholar) afin d’identifier les études évaluant l’efficacité de la RMO sur le SAOS. Le critère de jugement principal était une diminution de l’indice d’apnées/hypopnées (IHA) d’au moins cinq épisodes par heure par rapport à l’état initial. Les critères de jugement secondaires étaient une amélioration de la qualité subjective du sommeil, de la qualité du sommeil mesurée par polysomnographie nocturne et de la qualité de vie mesurée subjectivement. Résultats : Seulement dix études répondaient à tous les critères d’inclusion. Huit étaient des essais cliniques contrôlés randomisés, une était une étude de cohorte prospective et une autre était une étude de cohorte rétrospective. Six études étaient consacrées au SAOS de l’adulte et quatre au SAOS pédiatrique. Toutes les études incluses ont été évaluées à « faible risque de biais » d’après les douze critères de risque de biais du Cochrane Back Review Group. D’après les données probantes disponibles, la RMO permet une réduction significative de l’IAH, jusqu’à 90,6 % chez l’enfant et jusqu’à 92,06 % chez l’adulte. Elle permet une diminution significative de l’intensité et de la fréquence du ronflement, participe à une réduction de la somnolence diurne, limite la réapparition des symptômes d’apnée obstructive du sommeil (AOS) après adénoamygdalectomie chez l’enfant et améliore l’adhésion au traitement par ventilation en pression positive continue (PPC). La RMO passive, avec l’assistance apportée au patient par le port d’une orthèse sur mesure à bille, augmente l’observance à la rééducation, permet une réduction significative de l’intensité du ronflement, de l’IAH et un accroissement significatif des voies aérifères supérieures. Conclusions : Les données publiées montrent que la rééducation myofonctionnelle orofaciale est efficace dans les traitements multidisciplinaires des SAOS de l’enfant, de l’adolescent et de l’adulte et devrait être largement prescrite à plusieurs étapes de ces prises en charge. La RMO passive, avec l’orthèse d’avancée mandibulaire à bille conçue par Michèle Hervy-Auboiron, aide à pallier les fréquents défauts d’observance observés lors des traitements par RMO active.

Abstract Objective This metanalysis aimed to evaluate the sensitivity and specificity of computed tomography colonography in colorectal polyp detection. Methods A literature search was performed in the PubMed and Web of Science databases. Results A total of 1,872 patients (males 57.2%, females 42.8%) aged 49 to 82 years old (mean age 59.7 ± 5.3 years) were included in this metanalysis. The estimated sensitivity of computed tomography colonography was 88.4% (46.3–95.7%, coefficient of variation [CV] = 28.5%) and the estimated specificity was 73.6% (47.4–100.0%, CV = 37.5%). For lesions up to 9 mm, the sensitivity was 82.5% (62.0–99.9%, CV = 25.1%) and the specificity was 79.2% (32.0–98.0%, CV = 22.9%). For lesions > 9 mm, the sensitivity was 90.2% (64.0–100.0%, CV = 7.4%) and the specificity was 94.7% (80.0–100.0%, CV = 6.2%). No statistically significant differences in sensitivity according to the size of the lesion were found (p = 0.0958); however, the specificity was higher for lesions > 9 mm (p < 0.0001). Conclusions Most of the studies analyzed in the present work were conducted before 2010, which is about a decade after computed tomography colonography started being indicated as a screening method by European and American guidelines. Therefore, more studies aimed at analyzing the technique after further technological advancements are necessary, which could lead to the development of more modern devices.

Abstract Objective To investigate peer review practices by medical imaging journals. Methods Journals in the category "radiology, nuclear medicine and medical imaging" of the 2018 Journal Citation Reports were included. Results Of 119 included journals, 62 (52.1%) used single-blinded peer review, 49 (41.2%) used double-blinded peer review, two (1.7%) used open peer review and one (0.8%) used both single-blinded and double-blinded peer reviews, while the peer review model of five journals (4.2%) remained unclear. The use of single-blinded peer review was significantly associated with a journal’s impact factor (correlation coefficient of 0.218, P = 0.022). On subgroup analysis, only subspecialty medical imaging journals had a significant association between the use of single-blinded peer review and a journal’s impact factor (correlation coefficient of 0.354, P = 0.025). Forty-eight journals (40.3%) had a reviewer preference option, 48 journals (40.3%) did not have a reviewer recommendation option, and 23 journals (19.3%) obliged authors to indicate reviewers on their manuscript submission systems. Sixty-four journals (53.8%) did not provide an explicit option on their manuscript submission Web site to indicate nonpreferred reviewers, whereas 55 (46.2%) did. There were no significant associations between the option or obligation to indicate preferred or nonpreferred reviewers and a journal’s impact factor. Conclusion Single-blinded peer review and the option or obligation to indicate preferred or nonpreferred reviewers are frequently employed by medical imaging journals. Single-blinded review is (weakly) associated with a higher impact factor, also for subspecialty journals. The option or obligation to indicate preferred or nonpreferred reviewers is evenly distributed among journals, regardless of impact factor.
