Authors: Dziak L. A. , Shulha O. O. , Suk V. M.
Published: April 2023

Assessment of chronic factors of acute lumbosacral radiculopathy is an urgent problem due to the disease impact on the quality of life of patients, possible loss of work capacity and disability.
The aim of the work is to identify chronicity factors of acute compressive lumbosacral radiculopathy depending on the severity of degenerative-dystrophic changes in the spine and pathomorphological changes in the zone of disc-radicular conflict based on complex clinical-neurological, neuro-orthopedic, neuroimaging, neurophysiological and statistical methods of examination.
Materials and methods. 100 patients with acute lumbosacral radiculopathy were examined. The patients were divided into two groups: 45 patients with radiculopathy and both discogenic pathology and stenotic process in the spinal canal and/or lateral openings, and 55 patients with radiculopathy developed secondary to a pathology between the vertebral disc at the level of one vertebromotor segment. All the patients underwent neurological, neuroorthopedic, neurophysiological examinations. The study was conducted in two stages – 3–7 days and one months after the disease onset.
Results. On the basis of comprehensive clinical, neuroimaging, neurophysiological examinations and statistical processing of the obtained data, factors affecting the chronicity of acute compressive lumbosacral radiculopathy were identified: age (rs = 0.25, P = 0.012), sex (rs = 0.25, P = 0.012), pain syndrome severity according to the VAS (rs = 0.25, P = 0.011), the presence of a neuropathic component of pain according to the PainDETECT questionnaire (rs = 0.74, P < 0.001), biomechanical disorders of the spine during the Schober test (rs = -0.41, P < 0.001), lateroflexion (rs = -0.30, P = 0.003), extension (rs = 0.28, p = 0.004), damage to Aβ fibers (rs = -0.36, P = 0.009), Aδ-fibers (rs = -0.38, P = 0.006), C-fibers (rs = -0.37, P = 0.008), allodynia (rs = 0.38, P < 0.001), hyperalgesia (rs = -0.24, p = 0.014), muscular-tonic syndrome index (rs = 0.26, p = 0.008), the presence of lumbar canal stenosis (rs = 0.42, P < 0.001), spondyloarthrosis (rs = 0.22, P = 0.028), spondylolisthesis (rs = 0.20, P = 0.047).
Conclusions. The conducted study has revealed the main factors contributing to the development of acute lumbosacral radiculopathy chronicity. The presence of a neuropathic component of pain in the mechanism of pain syndrome development in the acute period of the disease and the involvement of C-fibers in the pathological process in the late stages of the disease are among the important markers contributing to the disease prolongation. Assessment of the factors that determine the chronicity of the course in the acute period of the disease allows to prescribe complex differential therapy at the early stage of the disease.
Fake accounts on social media, epistemic uncertainty and the need for an independent auditing of accounts
Authors: Moore Martin
Published: April 2023

This article seeks to understand why so little is known about the nature and extent of ‘fake or spam accounts’ across the leading social media companies, why this lack of knowledge is even greater outside the companies themselves and the implications of this epistemic uncertainty. It concludes that authorities, investors and the public should not be solely reliant on the companies for user account figures, and that there is a need for regular, independent, external audits of inauthentic accounts on social media.
Design of a compact metamaterial absorber with wide angular stability and polarisation insensitive for C, X and broad Ku band applications
Authors: Puri Vishal , Singh Hari Shankar
Published: April 2023

The article presents the design and development of a metamaterial-based microwave absorber having polarisation insensitivity, broad angle of incidence, low profile, and compactness in the microwave frequency range. The unit cell focuses to achieve maximum absorption at C-, X- and broad Ku-bands. The structure is simulated and the results are analysed for different angles of polarisation and angle of incidence. The dimension of the proposed structure is ultrathin and compact having an overall dimension of 8 mm × 8 mm × 0.8 mm. The dimensions are optimized in such a fashion to achieve three different peaks at three different bands thereby making the triple-band behaviour of the metamaterial absorber possible. The structure is providing absorption of 99.14% absorption at 6.08 GHz (C-Band) while absorption of 98.29% is achieved at 9.49 GHz (X-band) and 265 MHz bandwidth with above 95% absorption from 16.57 GHz to 16.83 GHz (Ku-Band) in the microwave regime. The absorber patch is a composition of square ring patches and a central square ring annexed with triangles on four sides, the split ring providing a combinational effect witnessing the desired absorption at designated frequencies. The unit cell dimension at a lower cut-off frequency is 0.162 λ
lowest. The proposed structure is verified for polarisation sensitivity and has a wide angle of incidence. The structure is experimentally verified for results and is found to be in close agreement with simulated ones. The compactness of structure with the attainment of the highest form of absorption in different bands including the 265 MHz high absorption band provides the scope of applicability in various engineering applications at microwave regimes.

Severe maternal thrombocytopenia and prenatal invasive procedures: still a grey zone
Authors: D’Alberti Elena , Brunelli Roberto , D’Ambrosio Valentina , Galoppi Paola , Santoro Cristina , Giancotti Antonella
Published: April 2023

Management of severe thrombocytopenia, particularly of ITP, in pregnancy is mainly based on expert consensus and clinical experience while there are no clear indications about the minimum platelet count requested for prenatal diagnosis invasive procedures. Since the lack of specific recommendations we reported our clinical management of a patient suffering from severe thrombocytopenia, undergoing amniocentesis. Due to the anecdotic possibility of maternal and fetal bleeding in case of severe thrombocytopenia, prophylaxis with IVIG or even corticosteroids could be considered as a safer strategy to prevent post-procedural adverse outcomes.
Nietzsche’s Heraclitus: Historical Figure and Personal-Philosophical Archetype
Authors: Rayman Joshua
Published: April 2023

The multiple sources and functions of Heraclitus in Nietzsche’s writings should not be underestimated. Nietzsche’s early readings of Heraclitus are steeped in the Greek fragments, the doxographical tradition, and in philological scholarship. Hence, they are largely either fair interpretations of the extant fragments, clear translations of a select group of fragments into his own language, or improvisations based in part on a narrow subset of the spurious remarks set down in the doxographical tradition. Nietzsche’s later departures from this tradition articulate an anti-metaphysical Heraclitus that he found in the Heraclitean fragments, which he takes to prefigure and later parrot his doctrines of becoming, the child, strife, chance, and eternal recurrence. For this reason, Nietzsche’s Heraclitus is necessarily no objective, individual historical person, but at various times and to various degrees a copy, an appropriative invention, and a personal-philological-philosophical archetype filtered through the lenses of ancient Greek understandings of how he must have lived, given what he said and what philosophy is; nineteenth-century German philological reconstructions of Heraclitean thought; and Nietzsche’s own need for such a precursor to voice his own doctrines and thereby lend them heft against the Platonic tradition of metaphysical philosophy.
Sociolinguistic variation, or lack thereof, in the use of the Italian subjunctive: mood selection with factive and semi-factive governors
Authors: Cerruti Massimo , Ballarè Silvia
Published: April 2023

This paper deals with various aspects of the use of the subjunctive in spoken Italian. Firstly, a brief overview is provided of the interplay of linguistic and extra-linguistic factors underlying the selection of the subjunctive in various syntactic structures. Special attention is paid to the differences in subjunctive use in factual and non-factual contexts, pointing out that the former are less studied and less affected by normative injunctions than the latter. The focus then falls on factual contexts, in particular subordinate clauses which depend on factive and semi-factive governors. The investigation is based on KIParla, a corpus of spoken Italian consisting of different types of interactions with speakers of various origins and social backgrounds. It is argued that in the factual context at hand the subjunctive fulfills a specific set of functions, mostly related to the speaker’s stance towards the content of the subordinate clause. Finally, a statistical analysis is performed using conditional inference trees and random forests in order to uncover the linguistic and extra-linguistic conditioning of subjunctive use. The analysis shows that in the context under observation it is only linguistic factors that significantly condition mood selection; the use of the subjunctive is substantially insensitive to socio-stylistic and geographic variation, and therefore a socially shared pattern of variation has emerged.

Published: April 2023

The industry is challenged to replace toxic chemical-based surfactants with environmentally friendly and biodegradable surfactants. In this study, binary mixtures of sodium lauryl sulfoacetate (SLSA) and an alkyl polyglucoside (APG10) in various proportions were investigated for their effectiveness as degreasing agents. Efficacy was characterised using surface tension measurements, oil dispersion tests, emulsification, pH and cleaning efficacy in removing engine oil from a metal plate. The surface tension results for all solutions showed a critical micelle concentration of 1500 ppm. The dispersion tests (with oil:surfactant ratios of 1:2 and 1:3) showed that the oil was fully dispersed at an oil:surfactant ratio of 1:2 i.e., at a concentration of 2500 ppm SLSA and 2000 ppm of a binary solution with a volume ratio of SLSA:APG10 of 75:25. At a ratio of 1:3, the oil was fully dispersed with 2500 ppm of a binary solution with a ratio of SLSA:APG10 of 75:25. Overall, the solution with a volume ratio of SLSA:APG10 of 75:25 was the most favourable. The results also showed that a solution containing only SLSA had good potential as a degreaser, as it achieved a cleaning performance of 90% in removing oil from the metal plate despite low emulsification levels (E24) for both surfactants. In summary, a combination of these two green surfactants can be used effectively as a degreasing agent.

Published: April 2023

The Ca2Pd2Ge-type stannides Sr2Pd2Sn and Eu2Pd2Sn were synthesized by reaction of the elements in sealed tantalum ampoules in a high-frequency furnace and characterized by powder X-ray diffraction. The structure of Sr2Pd2Sn (Fdd2, a = 1063.95(5), b = 1623.22(9), c = 594.63(14) pm, wR2 = 0.0472, 972 F
2 values and 26 variables) was refined from single-crystal X-ray diffractometer data. The striking structural motif features equidistant chains formed by the palladium atoms (304.7 pm Pd–Pd), which are interlinked by the tin atoms (266.9 and 268.7 pm Pd–Sn). Together, the palladium and tin atoms form a three-dimensional [Pd2Sn]
δ– polyanionic network in which the strontium atoms reside in larger cavities. The divalent character of europium in Eu2Pd2Sn was manifested by 151Eu Mössbauer spectroscopy. The isomer shift is δ = −9.48(1) mm s−1 at room temperature. The results of 119Sn Mössbauer-spectroscopic experiments have confirmed the tin site determined by the single-crystal study, the isomer shifts being δ = 1.71(1) mm s−1 for Eu2Pd2Sn and δ = 1.73(1) mm s−1 for Sr2Pd2Sn. Sr2Pd2Sn is a Pauli paramagnet with a susceptibility of 2.2(1) × 10−5 emu mol−1 at room temperature. Eu2Pd2Sn shows Curie-Weiss paramagnetism with an experimental magnetic moment of 7.85(1) µB per Eu atom, confirming divalent europium. The europium magnetic moments order antiferromagnetically at T
N = 14 K.

High‐content image‐based cell phenotyping provides fundamental insights into a broad variety of life science disciplines. Striving for accurate conclusions and meaningful impact demands high reproducibility standards, with particular relevance for high‐quality open‐access data sharing and meta‐analysis. However, the sources and degree of biological and technical variability, and thus the reproducibility and usefulness of meta‐analysis of results from live‐cell microscopy, have not been systematically investigated. Here, using high‐content data describing features of cell migration and morphology, we determine the sources of variability across different scales, including between laboratories, persons, experiments, technical repeats, cells, and time points. Significant technical variability occurred between laboratories and, to lesser extent, between persons, providing low value to direct meta‐analysis on the data from different laboratories. However, batch effect removal markedly improved the possibility to combine image‐based datasets of perturbation experiments. Thus, reproducible quantitative high‐content cell image analysis of perturbation effects and meta‐analysis depend on standardized procedures combined with batch correction.
Green Chemistry Education In The Emerging Economies In Asia
Authors: Jovero M. B. , Picardal J. P.
Published: April 2023

This paper aims to investigate and synthesize literature exploring the current state of Green Chemistry Education (GCE) in the emerging economies in Asia to determine what has been done and the continuing projects for the promotion of Green Chemistry (GC). The researchers used the integrative literature review approach to examine qualitative, quantitative, and mixed methods and empirical and theoretical literature related to GCE. This approach includes (a) problem identification, (b) search for structured literature, (c) data evaluation, (d) data analysis, and (e) presentation of findings. Published studies revealed that most initiatives in integrating GC principles in emerging economies in Asia focused on the secondary and tertiary levels but not graduate studies and non-chemistry-related courses. Most of its progress has been observed in Organic Chemistry and General Chemistry. Results also revealed that the barriers that hampered integrating GCE are pedagogical resources (insufficient or unavailability of time, financial and technological resources) and pedagogical content knowledge (misconceptions about GC, lack of expertise, and the need to update technical knowledge). It can be concluded that even in the initial stage of implementation of green chemistry education in the emerging economies in Asia, and despite numerous documented barriers, proactive efforts are being made by numerous institutions and even individuals who are tenaciously advocating green chemistry. These efforts are enriched through various educational programs, learner-centered pedagogical practices, and strategies that enhance teachers’ and students’ content knowledge and skills. Finally, economics is a major factor in determining a country’s state of Green Chemistry as the economic condition can be credited to outstanding or dismal achievements.

Effect of the surface finishing methods on particleboard volatile organic compounds and formaldehyde emission
Authors: Chen Feng , Shen Jun , Xia Xinghua
Published: April 2023

Chemical contaminants from wood-based panels, such as volatile organic compounds (VOCs) and formaldehyde, are the main sources of indoor air pollution. The particleboards were used as the substrate and five common finishing methods, including melamine-impregnated paper, high-density polyethylene decorative film, wood veneer, polypropylene water borne paintings coatings, and polyurethane water borne paintings coatings, were selected for this study. The emission curves in the first 6 h and the equilibrium concentrations of the total volatile organic compounds (TVOC) and formaldehyde processed with the finishing wood-based panel method for 24 h were obtained and measured using an airtight environmental chamber. The ingredients of the VOCs were investigated using the small chamber method and gas chromatography and mass spectrometry (GC/MS). The results indicated that the finishing methods were effective for reducing the emissions of TVOC (except the water borne coating) and formaldehyde of the particleboards. High density polyethylene film was the best finishing material to reduce the release of TVOC. The concentration of the veneered particleboard from the third to the tenth hour was higher than the unfinished particleboards. The veneered particleboard released six volatile ingredients to a lesser extent than the unfinished particleboard.
Fire Safety and Prevention Issues in Design of Tall Buildings
Authors: Yılmaz Didem Güneş
Published: April 2023

Fire safety design of tall buildings is crucial. The number of floors, the function, and the occupants' features build the complexity in the life and fire safety design of tall buildings. Because of the complexity of each tall building design, specific preventive measures are necessary more than the basic requirements given in the national and local codes. The fire safety design of the world-renowned tall buildings, including Guangzhou International Finance Centre (IFC), Capital Market Authority (CMA) Tower, and Jin Mao Tower are case studies and further focus is made on the facade design of tall buildings. The paper reviews the safety design issues and focuses on the fire evacuation models, estimations, and the effect of different parameters in the success of fire safety design of tall buildings. In addition to the various fire evacuation suggestions, the effect of human behavior in fire is also discussed through the literature review. Fire safety is not only an engineering problem to deal with, but also architects must know the holistic approach in the fire safety design of tall buildings since it involves their architectural design as well. The paper aimed to bring the most arguable issues in the fire safety design of tall buildings together and to highlight the value of different perspectives in achieving a promising fire safety design.

Published: April 2023

The aim is to evaluate Rowling’s world of fairy tales and its adherence to the criteria of a fantasy secondary world according to the frameworks proposed by T. Todorov (1973), R. Jackson (1981), and F. Mendlesohn (2008). The secondary world in the Harry Potter series, the wizarding world, is open to the real world and shares its geography, yet hidden from non-magical people. It is consistently described with its own culture, customs, traditions, and social norms. The central conflict is between Good and Evil for domination, with Evil aiming to extend its power to both the magic world and the real world. The fantasy world is relatable to readers due to its handling of universal themes and issues relevant to their lives, transferring characters into new life conditions. Research methods include content analysis, psychological research, and comparative analysis.
Antonyms, or Antagonism in Language (on the Example of Feelings of Love and Hate)
Authors: Wójcik Magdalena Ambra
Published: April 2023

The aim of the article was to show the opposition of lexemes love and hate by carrying out a pragmatic-discursive analysis of them (with a particular emphasis on the Biblical Discourse). It was concluded that from the semantic point of view, love and hate are long-lasting feelings with a strong emotional charge in opposition to each other. The expressions containing such a component as hate in various word forms have an unambiguously negative connotation while using the words love in most cases makes the message positive. The antagonism of the language units mentioned above is particularly evident in the Biblical Discourse, which is conditioned by the didactic-moralistic nature of the text.

Students of Russian law universities in the context of the state of the professional educational environment
Authors: Levina Raisa
Published: April 2023

The article is dedicated to the issues of professional socialisation of legal students in modern Russia. The relevance of this research topic is defined by the meaningfulness of the successful formation of professional legal culture among legal students while studying at university and professional socialisation from the perspective of increasing the overall level of legal culture in the society and the efficiency of its legal institutions. The latter contains especially topical social and practical aspects for the contemporary Russian society which still experiences the consequences of social anomia and weakened legal control describing the initial period of system reforms. Making an attempt to solve the task, the author resorts to the methodology of Parson’s structural functional approach, as well as to the socio-cultural approach. The author gives a detailed review of functional and role specific features of legal community and their value for modern developed society. According to the author’s opinion, effective formation of professional legal culture while studying at university is required to provide the functionality of lawyers which first and foremost is related to comprehension of the rule of law as the highest professional value. Within this framework legal students are considered as representatives of young generation of Russian people. The author is pointing at the dominance of pragmatic and individualistic mindset when they enter legal educational establishments, which creates potential risk for the rule of law to be devalued in their professional motivation. The article underlines the communal value of effective professional socialization of legal students. The author studies the features of educational environment as its agent emphasizing the factors of insufficiency of students’ socialization in legal universities from the point of view of shaping the value of the rule of law as the fundamental professional priority

Authors: Garcia Teise de Oliveira , Adrião Theresa , Drabach Nadia , Santos Maria
Published: April 2023

Abstract This article analyzes the 2nd generation of public education privatization in São Paulo. Such categorization stems from a study of the processes that institutionalized the incidence of the private business sector in education since 1995. The period corresponds to the effectiveness of Resolution SEE no. 24, of April 5, 2005, during the Alckmin administration, which incorporated the recently created Associação Parceiros da Educação, a network of entrepreneurs, and instituted the Empresa Educadora program. The documentary research and the analysis of the educational offer conditions in 21 school units in the state of São Paulo indicated that the objective of promoting the improvement of the educational offer conditions was not verified. Corporate action in educational policy in an articulated way, however, was implemented.

RESUMO Na abertura da icônica exposição China/Avant-Garde (1989, Pequim), a artista Xiao Lu disparou dois tiros contra sua instalação Dialogue e entregou a arma ao artista Tang Song, que mais tarde se tornaria seu namorado. A partir daquele momento, o mundo da arte atribuiu a peça a Tang Song e Xiao Lu. Duas décadas depois, Xiao Lu disputou a autoria exclusiva da obra de arte em um livro de memórias ficcionais, Dialogue (2010). Nesse texto, ela apresentou uma historiografia de sua arte, refletindo sobre a performance e desafiando a apropriação da obra por Tang Song. Este artigo explora a reescrita de Xiao Lu a respeito da história oficial da arte e seus fundamentos patriarcais por intermédio de uma lente feminista. Abarca leituras complementares, contraditórias e contrastantes da arte de Xiao Lu e oferece uma nova abordagem tanto à dimensão terapêutica como política do relato autobiográfico da artista.

ABSTRACT At the opening of the iconic exhibition China/Avant-Garde (1989, Beijing), the artist Xiao Lu fired two shots at her installation Dialogue and handed the gun to the artist Tang Song, who would later become her boyfriend. From that moment on, the artworld attributed the piece to Tang Song and Xiao Lu. Two decades after the event, Xiao Lu disputed the unique authorship of the artwork in a fictional memoir, Dialogue (2010). In this text, she presented a historiography of her art, reflecting on the performance and challenging Tang Song’s appropriation of the work. This article explores Xiao Lu’s re-writing of the official history of art and its patriarchal foundations through a feminist lens. It engages with complementary, contradictory, and contrasting readings of Xiao Lu's art and offers a new approach that addresses both the therapeutic and political dimensions of the artist's autobiographical account.

Abstract: Asymbiotic germination techniques are successful in species of the Catasetum genus. The diverse composition of the culture media can be critical; however, viable seeds are required for asymbiotic germination. The reliable method for viability assessment is the tetrazolium test. A decisive step in the efficiency of the tetrazolium test is the seeds preconditioning with sucrose solution, which has the potential to improve germination. Therefore, this work aimed to evaluate the seed germination of three species of the genus Catasetum in culture media, preconditioned or not with sucrose solution. Seeds of the species Catasetum osculatum, Ctsm. galeritum and Ctsm. complanatum were assessed by tetrazolium test and germinated in two different media, pretreated or not with 10% sucrose solution. The statistical analysis showed that the use of sucrose pretreatment significantly increased the germination rates of the species. We conclude that the pretreatment with 10% sucrose for 24 hours, regardless of the species and the culture medium, significantly increases the germination of Ctsm. complanatum, Ctsm. galeritum and Ctsm. osculatum seeds.

Introduction of molecules into the cells is part of gene transfection or cell-mediated drug delivery. The molecules can effectively decrease side effects of the drug and increase their targeting. Air microplasma discharge was used to treat rat intestinal cells to induce absorption of fluorescein isothiocyanate-dextran with a molecular weight of 150 kDa (FD-150). Absorption of FD-150 was confirmed by observation using fluorescence microscope. Efficiency of absorbance was estimated by a plate reader, and the viability of the cells was measured by a cell counter. The viability of the cells was proportional to the decrease in treatment time and the increase in treatment distance from the microplasma electrode. The absorption of FD-150 was found to be proportional to the increase in time and distance. No improvement in absorption or viability was observed during the incubation time. Cell treatment by the plasma-treated medium showed a lower absorption of FD-150 than direct treatment but the same cell viability. Concentration of ozone in the gas phase and OH radical in the liquid phase were observed.

La plongée sous-marine expose à des accidents très spécifiques que l’on répartit classiquement en fonction des lois
physiques qui régissent ce milieu hostile : les accidents barotraumatiques liés aux conséquences de la variation des
volumes gazeux soumis aux variations de pression, les accidents biochimiques (ou toxiques) liés à la réactivité
biologique des gaz sous pression, et les accidents de désaturation liés aux conséquences de la dissolution des gaz diluants
dans l’organisme. D’autre part, les contraintes environnementales du milieu génèrent également un accident cardiorespiratoire
spécifique de révélation récente : l’oedème pulmonaire d’immersion aux conséquences parfois dramatiques.
Narcose aux gaz inertes : risque cognitif pour l’équipage d’un sous-marin en détresse et pour son équipe de sauvetage

Dans un sous-marin en détresse avec une voie d’eau, la compression de l’air présent dans un compartiment augmente la
pression partielle d’azote, soumettant ainsi l’équipage à un risque de narcose. Afin de pouvoir se connecter à ce sousmarin,
le véhicule de secours doit être à la même pression. L’équipe médicale intervenante est ainsi soumise au même
risque. La narcose entraîne des symptômes apparents, mais aussi une dégradation du traitement sensorimoteur,
potentiellement dangereuse pour le bon déroulement de la mission de sauvetage. Le traitement sensorimoteur est en effet
à la base de la majeure partie des actions volontaires. Afin d’appréhender l’impact de la narcose dans le contexte du
sauvetage de sous-marin, nous avons bénéficié de sessions de plongées d’essais à saturation, ce qui nous a permis de
comparer une condition non narcotique (normobare) à une condition narcotique (hyperbare). Les plongeurs ont réalisé,
dans ces deux conditions, une tâche particulière permettant l’étude spécifique de l’étape décisionnelle du traitement
sensorimoteur. La méthode des facteurs additifs a confirmé l’altération de cette étape par la narcose.

La recherche biomédicale est définie par le Code de la santé publique comme « une recherche organisée et pratiquée sur
l’être humain en vue du développement des connaissances biologiques et médicales ». Plusieurs étapes historiques depuis
la fin du XXe siècle ont permis d’établir les grands principes de l’éthique dans l’expérimentation humaine avec des textes
internationaux (déclaration d’Helsinki), européens (Directives et règlements européens) et nationaux. La réglementation
en vigueur résulte de plusieurs textes de loi portant sur la protection de la personne humaine dans le cadre de la recherche
médicale et l’utilisation des données personnelles et des produits issus de la personne. La recherche clinique du Service de
santé des armées a pour but d’améliorer la santé de la communauté de Défense. L’article décrit les étapes incontournables
de la conduite d’une recherche biomédicale sur la personne humaine à destination des praticiens du Service de santé des
armées, en tenant compte des bonnes pratiques cliniques et des spécificités du Service.

Suite au déclenchement de l’opération « Serval » au Mali en janvier 2013, il s’est avéré rapidement nécessaire, compte
tenu des élongations importantes, de déployer un aéronef tactique médicalisé. Équipée du nouveau lot CM30, une équipe
MEDEVAC a effectué, durant le premier mois, dix missions aéro-sanitaires à bord d’un CASA CN 235-200. Trente-sept
patients ont été évacués, dans des états souvent graves, pour la plupart blessés de guerre. Il a semblé intéressant aux auteurs
d’effectuer une étude descriptive de cette mission.

Objectif : l’objectif du projet de recherche MoCoDeS (Motifs de Consultation Dentaire en urgence au cours de l’opération
« Serval ») est d’identifier le type de pathologies bucco-dentaires rencontrées en opération afin de pouvoir les prévenir par
la mise en place de mesures adaptées et ainsi de permettre aux armées de disposer en opération de militaires effectuant leur
mission sans perte de temps ni d’efficacité attribuable à une cause dentaire. Méthode: les données relatives à la prise en
charge des urgences au cabinet dentaire implanté au sein du groupement médico-chirurgical de Gao (Mali) ont été recueillies
du 19 juillet 2013 au 24 mai 2014. Résultats : 556 urgences dentaires ont été comptabilisées au cours de la période couverte
par le projet MoCoDeS. Les caries dentaires sont le premier motif de consultation dentaire en urgence (51,6 %). La majorité
des urgences dentaires (61,3 %) est liée à des pathologies préexistantes avant la projection et/ou à des comportements à
risque d’un point de vue odontologique (mauvaise hygiène alimentaire et bucco-dentaire). Conclusion : la majorité des
urgences dentaires au cours des opérations extérieures peut être prévenue par la mise en place d’une stratégie globale
d’amélioration de la santé bucco-dentaire des militaires incluant le dépistage, la prévention et les soins. Un partenariat avec
la caisse nationale militaire de sécurité sociale pourrait permettre le financement et la mise en oeuvre d’une telle stratégie
à travers une déclinaison militaire du bilan bucco-dentaire de prévention civil mis en place à destination des enfants et
des adolescents (bilan M’T dents) et une amélioration de l’hygiène alimentaire et bucco-dentaire au cours des opérations.
