L’ambiance olfactive : de la théorie à la pratique d’enseignes de supermarchés
Authors: Frikha Azza
Published: May 2022

L’objectif de l’article est d’explorer les pratiques olfactives de certaines enseignes. Des entretiens semi-directifs avec des directeurs marketing d’enseignes de supermarchés ont permis, suite à une analyse de contenu, de mieux cerner l’intérêt accordé à l’odeur ambiante. Il a été observé que les interlocuteurs sont conscients de la puissance de l’odeur à générer une multitude de réactions des clients. L’utilisation d’une odeur plaisante au sein des supermarchés est toutefois limitée. Par ailleurs, il semble qu’une stimulation olfactive est déterminée à travers sa plaisance et sa congruence avec les produits, le magasin et ses composantes atmosphériques.
L’émergence de biais comportementaux en situation de trading : une étude exploratoire
Authors: Finet Alain , Kristoforidis Kevin , Viseur Robert
Published: May 2022

Les modèles de compréhension des marchés boursiers font principalement la part belle aux approches fondamentales et techniques, tout en prenant soin de se référer également à la finance comportementale, mais peu a été développé sur les biais psychologiques selon une approche qualitative, notamment pour les petits porteurs. En partant du constat que le traitement de l’information est plus aisé pour les acteurs institutionnels et que les outils techniques présentent des niveaux d’opérationnalité très variables, le petit investisseur est bien souvent livré à lui-même, influencé par des éléments qui dépassent le cadre de la rationalité. Notre analyse porte sur les biais comportementaux sous-tendus par des champs émotionnels qui pourraient influer sur le processus décisionnel de petits porteurs. À cette fin, nous avons mobilisé un groupe de 15 étudiants en situation de trading continu durant une semaine boursière. Cette expérimentation a correspondu à un contexte boursier spécifique ; il n’en demeure pas moins que les participants ont été soumis à des charges émotionnelles conduisant à l’émergence de certains biais comportementaux. Les conclusions auxquelles nous parvenons démontrent que ceux-ci peuvent, dans certains contextes, constituer des leviers de création de valeur financière.
La domination touristique
Authors: Hanson Pastran Sasha , Bordas Mathilde , Polet François
Published: May 2022

Les travers néocoloniaux du tourisme sont bien connus. De nouvelles niches sont apparues au sein de ce marché au cours des années 1980, qui proposent aux touristes un rapport plus respectueux et solidaire aux communautés et territoires visités. L’étude de ces initiatives sous l’angle des théories postcoloniales révèle néanmoins qu’elles peinent à s’extraire des mécanismes inégalitaires de la rencontre touristique.
La domination touristique
Authors: Jeannite Sadais , Sarrasin Bruno
Published: May 2022

Au fil des dernières décennies, les pouvoirs publics haïtiens ont élaboré des politiques de développement consacrant le processus de diffusion du tourisme dans l’économie. Sous l’égide des institutions financières internationales, cette mise en tourisme de la « perle des Antilles » a surtout consisté à créer les conditions propices à l’implantation d’entreprises étrangères et à la reproduction des asymétries structurelles du système mondial.
La Croix du Christ et le rapatriement de toute chair. Le rite ouessantin de proella
Authors: Montoux Arnaud
Published: May 2022

L’épreuve de la perte des corps, quand elle s’ajoute au deuil, creuse des abysses dans la chair des survivants. La pandémie à laquelle nous sommes confrontés depuis deux ans a fait ressurgir pour nombre de nos contemporains l’angoisse ancestrale d’avoir dû laisser l’aimé mourir seul et de n’avoir pas pu reconnaître son corps. Il y a plusieurs siècles, pour des raisons bien différentes liées aux dangers de la mer, les habitants de l’île d’Ouessant, en Finistère, ont cherché à trouver des rites et des objets capables de les aider à traverser l’épreuve de la disparition de leurs marins. Dans cette étude, nous chercherons à comprendre les mécanismes qui ont pu conduire cette population insulaire à choisir de petites croix de cire – les croix de proella – pour symboliser les corps des disparus dans une sorte de rite de rapatriement. Ce geste pauvre, ancré dans la parole donnée du Christ, ramène les chrétiens au Mystère dans lequel s’entrecroisent et se lient le « non-lieu » de la disparition et la « lieu-tenance » du Crucifié.
Mort dérobée ? Des conditions éthiques de la réintégration de la mort dans la vie
Authors: Trébuchet Marie-Dominique
Published: May 2022

Tout au long du xx e  siècle, les progrès des techniques biomédicales ont transformé le rapport à la mort en la soustrayant violemment à la vie ordinaire. Alors que les débats autour de la mort se polarisaient entre expropriation et réappropriation, l’apport de moralistes chrétiens a contribué à ouvrir une voie de réintégration de la mort dans la vie. Aujourd’hui, alors que le contexte de pandémie surexpose la mort tout en confrontant à nouveau violemment le sujet singulier à la disparition du mort, la réflexion éthique est sollicitée à partir de ses ressources propres. De la « mort dérobée », elle recueille la détresse de l’expression pour y discerner une quête d’humanisation en termes d’acceptation de la mort.
Esquisse d’une théorie générale de l’affectivité à partir de l’ontologie dynamique de Renaud Barbaras
Authors: Deudon Aurélien
Published: May 2022

La phénoménologie de Renaud Barbaras se réclame à maintes reprises de l’appel d’Edmund Husserl à déréifier le sujet et, en même temps, se refuse à faire de lui une instance extra-mondaine comme le soutient le transcendantalisme husserlien. Or, par rapport à cette double exigence, l’intimité subjective des phénomènes affectifs semble opposer une résistance particulièrement tenace. Cet article s’évertue à lever celle-ci en proposant une architectonique de l’affectivité, de ses ordres et de ses registres, qui s’appuie sur l’ontologie dynamique de Barbaras, prolonge certaines de ses indications, et intègre son analyse du Sentiment. Prenant distance ou relevant des filiations avec d’autres phénoménologies, cette Esquisse tente de montrer qu’on ne peut pas désubstantialiser les divers phénomènes affectifs sans faire droit à leurs puissances propres de manifestation du monde et de ses étants.
Reconnaissance ou mésentente ?
Authors: Deranty Jean-Philippe , Genel Katia
Published: May 2022

Axel Honneth a élaboré une critique de la société moderne au prisme du concept de reconnaissance. Jacques Rancière a construit une théorie de la politique moderne à partir du concept de mésentente. Ils s’attachent tous deux à analyser les logiques d’exclusion et de domination qui structurent les sociétés contemporaines. Dans un précieux dialogue, les deux philosophes explorent les affinités et les tensions entre leurs approches respectives. Ils contribuent ainsi à renouveler le cadre d’une théorie critique et à repenser les conditions du changement social et politique. La discussion est enrichie par des textes des deux penseurs, et elle est précédée d’une présentation substantielle qui remet en perspective ce dialogue critique.
Éthique de la nature ordinaire
Authors: Beau Rémi
Published: May 2022

Faut- il que la nature soit vierge ou intacte pour se voir reconnaître une valeur ?

C’est l’idée que les premières philosophies environnementales, apparues dans les années 1970 et centrées sur la nature sauvage ou la notion de wilderness, semblaient conforter. Ce faisant, elles laissaient penser que, sur les terres habitées ou transformées par les hommes - qui couvrent la majorité de la surface de la planète -, il fallait renoncer à penser la nature. Dépassant cette approche dualiste opposant préservationnistes et modernistes, l’auteur explore une voie médiane : contre l’idée que la nature résiderait seulement dans quelques lieux remarquables, il propose d’appréhender la gamme différenciée de nos rapports à la nature quotidienne. Car il y a bien de la nature dans les sociétés humaines et, en regard, nous faisons société avec elle. C’est en immersion dans les mondes agricoles et en avançant une description des pratiques multiples qui, dans les champs, les friches et les jardins, nous mettent en relation avec des partenaires non humains, que cet ouvrage propose donc l’élaboration d’une éthique de la nature ordinaire.
Married to the Cape: Adam West, Batman and Signature Roles on the Small Screen
Authors: Sweeney Carl
Published: May 2022

Influential theoretical paradigms posit that television is unlike cinema because it creates personalities rather than stars. Conversely, Deborah Jermyn challenges prior theories through analysis of Sarah Jessica Parker’s image, suggesting that it may be time to revisit the notion that true stardom needs to be associated with a range of different roles. However, though this is pertinent to contemporary figures, it is also relevant to those who came earlier. In particular, American television stars of the 1960s and 1970s were likely to be defined by their connection to a flagship part, due to a variety of factors that helped cement such associations.By theorising star status for someone linked with a single role, a distinct form of televisual fame comes into focus. To argue this, this article proposes a new category of stardom, described by the term ‘signature role TV star’. It evaluates Adam West, best known for his leading role on Batman (ABC, 1966-1968), as an archetypal example. Despite its initial popularity, Batman was cancelled after three seasons and West was unable to develop a lasting career as a mainstream leading man, meaning that his signature role remained the defining aspect of his stardom. Nevertheless, his image acquired productive new inflections over time, especially once his screen persona amplified the ludicrousness he displayed as Batman. Therefore, West embodies not just the ambivalences of being associated with a signature TV role, but also the advantages.
From Friends to “The Girl Friend”: the Early Evolution of Jennifer Aniston’s Star Image
Authors: Thrasher Chenot Jessica
Published: May 2022

In the more than twenty-five years since the spectacular success of the iconic television sitcom/cultural phenomenon Friends (NBC, 1994-2004), the ensemble program’s six actors have parlayed that visibility into careers of varying success on network and cable television, streaming platforms, and the film industry. One of them, Jennifer Aniston, has managed to maintain a consistently visible star image which continues to resonate with fans and critics alike. In her nearly thirty-year career Aniston has successfully transitioned from her role on the small screen to starring roles in feature films, and most recently gaining critical and popular attention (as well as a Screen Actor’s Guild award) for her role in The Morning Show on the Apple + streaming service. While scholars have already considered work from her late and post-Friends career, this article examines her breakout role as the appealing and attractive Rachel Green as an effective vehicle for the transition into her early film roles (1997-1998). Through an analysis of various texts and paratexts, the article traces the roots of the actress’ early star image and argues that understanding Aniston as capable of playing both erotically charged objects of desire as well as fully agential desiring subjects is key to explaining her early star image.
A “very politically correct, wholesome family show”: Jane Seymour’s white, heterosexual femininity in Dr. Quinn, Medicine Woman
Authors: Eaton Oline
Published: May 2022

In January 1993, the US television station CBS premiered a new TV drama about Michaela Quinn—a Boston doctor who moved alone to the Colorado frontier to establish her medical practice. Seymour’s biography played a critical role in the initial promotion of the show. The character of Dr. Quinn, as Seymour played her, was a feminist in the Hillary Rodham Clinton vein, and the show’s drama primarily revolved around Quinn’s gender deviance and issues arising from white patriarchy. Given this progressive, feminist bent, it’s surprising that the show resonated with conservative audiences and, in U.S. syndication, found a home on evangelical Christian networks such as PAX-TV and INSP. Combining media analysis, cultural analysis, and biographical research, this article analyzes how Jane Seymour’s star image and biography enabled Dr. Quinn to interrogate and challenge gender roles while also working to bolster the show’s position as “family values” TV. Ultimately, this analysis reveals the powerful role a star’s biography can play in disseminating ideas to diverse, sometimes potentially resistant, audiences.
“He’s Not Good, But He’s Not Bad”: Jason Bateman as the White, Middle-Class Devil
Authors: Selznick Barbara
Published: May 2022

Jason Bateman, as a former child star, a Hollywood party-boy-turned-family-man, and a seemingly un-aging actor imbued with privilege, created a persona that is instrumental for understanding the television shows (and films) in which he stars. Combining the rationality and order often associated with whiteness and the authoritative expertise connected to patriarchal privilege, examining Bateman in relation to his performances reveals the problematic position of dominance that he embodies. This essay argues that Bateman’s public image, as shaped by his publicity along with his role on Arrested Development, positioned him to – as an actor, executive producer, and director on Ozark – develop a character who offers a potential critique of hegemonic ideas about white, middle-class masculinity.
RETRACTED: Can We Fight EU-Racism in Football?
Authors: Tarnanidis Theodore , Tsaples Georgios , Papathanasiou Jason , Armenia Stefano
Published: May 2022

The current study aims to examine the phenomenon of racism in football. The researchers collected data from people of all ages in the countries of Italy, Romania, Greece, Hungary, Serbia, Bulgaria, and a number of experts from other countries as well. Data were analysed and studied through the use of descriptive statistics and correlation analysis. The findings suggest that racist incidences in football are very frequent. Furthermore, it was observed that social-demographic variables seem to affect people's propensity to racism, and usually, the respondents believe that racist acts are performed mainly due to lack of education, out of fear, and due to general social unrest. Finally, a thorough discussion and conclusions are given for the improvement of regulations at a European level to tackle the incidents of racism abuse in the sphere of soccer.

Adversarial Training for Predicting the Trend of the COVID-19 Pandemic
Authors: Wang Haishuai , Ma Jiali , Zhao Ziping , Jia Zhenyi , Ji Zhenyan , Wu Jun
Published: May 2022

It is significant to accurately predict the epidemic trend of COVID-19 due to its detrimental impact on the global health and economy. Although machine learning based approaches have been applied to predict epidemic trend, standard models have shown low accuracy for long-term prediction due to a high level of uncertainty and lack of essential training data. This paper proposes an improved machine learning framework employing Generative Adversarial Network (GAN) and Long Short-Term Memory (LSTM) for adversarial training to forecast the potential threat of COVID-19 in countries where COVID-19 is rapidly spreading. It also investigates the most updated COVID-19 epidemiological data before October 18, 2020 and model the epidemic trend as time series that can be fed into the proposed model for data augmentation and trend prediction of the epidemic. The proposed model is trained to predict daily numbers of cumulative confirmed cases of COVID-19 in Italy, USA, China, Germany, UK, and across the world. Paper further analyzes and suggests which populations are at risk of contracting COVID-19.
Promoting SMEs in Pacific Island Countries Through Effective Marketing Strategies
Authors: Jayawardena Nirma Sadamali , Boe Jack , Rohoia Angeline , Sharma Parmendra
Published: May 2022

This study provides the first systematic review of the different marketing strategies used for promoting SMEs in Pacific Island Countries (PICs). Literature published in high-ranked management journals was reviewed in this area using PRISMA guidelines published between 2000 to 2020. The study identifies three major marketing communication strategies useful for SMEs in the PICs: digital marketing strategies, market orientation strategies and experience based marketing strategies. Further, this study includes a detailed future research agenda under these three major themes. The digital marketing strategies are divided further into social media marketing strategies, blogs, and company websites. Market orientation strategies were categorised as the role of infrastructure development and the role of innovation. The experience-based marketing is another marketing strategy to attract customers (Nair & Chelliah, 2012a). For example, it is identified through the literature that PICs can focus more on cultural festivals and cruise ship markets.
Antecedents of Buying Behavior Patterns of E-Consumers
Authors: Srivastava Gautam , Bag Surajit
Published: May 2022

In the new digitalized era, seller and buyer interact at the market space whereby the market space is provided on a different digital platform. Gradually, consumers are transforming into e-consumers. The COVID-19 pandemic has changed consumers' purchasing patterns. During the lockdown, e-commerce firms expanded at a breakneck rate. It becomes crucial for e-commerce companies to analyze the buying behaviour pattern of e-consumers during this phase. So, a study is needed to analyze the changing buying behaviour of consumers towards online shopping. A structured questionnaire was designed to collect the data from 400 respondents. SPSS 20 and AMOS 20 were further used for the analysis of data. Findings indicate important antecedents of the buying behaviour pattern of e-consumers. The proposed model represents the buying behaviour pattern of e-consumers during the COVID-19 pandemic, which may help e-commerce companies to acquire new consumers and retain the existing ones.

Published: May 2022

Consumers get innumerable product options, making it crucial to study their selection among brands v/s new brands. The study explores how in a post covid world, the online purchase behavior of Generation Z female consumers is impacted for new-brand beauty products. Using qualitative methods, the authors explored the online purchase behavior of Generation Z females for the purchase of beauty products in emerging economies and how blockchain technology (BCT) can play a crucial role in influencing consumer decision-making. Five focus group discussions were conducted. The study’s findings reveal four key themes – “It's too hard to be an innovator,” “Online stigma,” “New brand reservations,” and “BCT and new brands purchase decisions.” The authors portray that generation Z consumers don’t feel competent enough to buy new brands online without extrinsic motivation. They do not entirely trust the information marketers provide them in the current form. They are expected to buy new brands online if the authenticity of the complete product details can be verified using blockchain mechanisms.

Big Data Analytics Capability and Business Alignment for Organizational Agility
Authors: Xie Chaohong , Xu Xianhao , Gong Yeming , Xiong Jie
Published: May 2022

This paper investigates the impact of big data analytics capability (BDAC) on organizational agility under the moderating effect of BDAC–business alignment and its impact on performance through organizational agility. Data from a matched-pair survey of business, data technology, and financial executives in 161 organizations were used to examine the proposed research model. This paper used partial least squares–structural equation modeling and hierarchical component analysis to examine the data. The results suggest a positive mediation role of organizational agility in the relationship between big data analytics capability and organizational performance, except that the mediation effect of operational adjustment agility on BDAC and market performance is not statistically significant. This study also finds that alignment between the business strategy and the big data analytics strategy enhances the relationship between BDAC and market responsiveness agility. It proposes a new perspective which is to realize the value of BDAC in enhancing agility and performance.
The Effect of Social Support on Emotional Labor Through Professional Identity
Authors: Zhao Hengchun , Fan Youqing , Zheng Leven J. , Liang Xiaoyan , Chiu Weisheng , Jiang Xue , Liu Wei
Published: May 2022

Drawing on the conservation of resources (COR) theory, the authors investigate whether and how social support impacts the emotional labor of live streamers through professional identity. They also explore the boundary conditions by focusing on the moderation effect of emotional intelligence. Based on a sample of 331 live streamers in the content industry, the results show that social support weakens (enhances) live streamers' surface acting (deep acting) by enhancing their professional identity. Emotional intelligence significantly moderates the professional identity-emotional labor relationship. In addition, they find that emotional intelligence strengthens the negative indirect effect of social support on surface acting through professional identity but weakens the positive indirect effect of social support and deep acting through professional identity. They also discuss theoretical contribution in emotional labor literature and practical implications for live commerce.

Authors: Li Mingyang , Bi Xinhua , Wang Limin , Han Xuming , Wang Lin , Zhou Wei
Published: May 2022

Text similarity measurement is a link between basic research such as text modeling and upper-level application research of text potential information. In order to improve the accuracy of text similarity measurement, this paper proposes a semantic similarity calculation method integrating word2vec model and TF-IDF, and applies it to the density peak clustering of Chinese text data consulted by patients in online medical community. Experimental results show that the proposed similarity measurement method is superior to the traditional method. Furthermore, the study is among the first to apply the density peak clustering algorithm to online medical community, which offers a reference for how to find out user demands from medical text data in the big data environment.
UTILIZAÇÃO DE MALHAS CIRÚRGICAS VERSUS OUTRAS TÉCNICAS NO TRATAMENTO DE HÉRNIAS: UMA REVISÃO SISTEMÁTICA
Authors: CARVALHO GABRIEL ALEIXO DOS SANTOS , Júlia Maia Guilherme Maria , Zayane Barros Freitas Damara , Lyev Bidô Alves Lincoln , Lopes Nóbrega Rafael , Nunes Alves de Sousa Milena
Published: May 2022

Introdução: hérnias são definidas como a distensão não fisiológica de algum órgão para fora da cavidade ou estrutura que a contém.  A hérnia comum no adulto é a inguinal, enquanto a hérnia mais comum na faixa etária pediátrica é a umbilical. Objetivo: avaliar, em pacientes submetidos à herniorrafia, a eficácia da malha cirúrgica em relação a outros materiais ou nenhum material para o reparo das hérnias. Método: trata-se de uma revisão sistemática realizada a partir de buscas nos seguintes bancos de dados: Biblioteca Virtual em Saúde (BVS), Medical Publisher (PubMed), EBSCOhost e Scientific Eletronic Library Online (SciELO). Foram utilizados os descritores “hérnias” AND “telas cirúrgicas” AND “próteses” e, em inglês, “hernias” AND “surgical mesh” AND “prostheses”. Dos 449 artigos encontrados, 5 foram utilizados para compor a discussão. Resultados: a maioria dos artigos não apontou diferenças importantes para o sucesso dos hernioplastias quando comparado o uso de malhas cirúrgicas à utilização de telas, nenhum material ou enxerto de pele (n=3), enquanto dois trabalhos apontaram melhores resultados com a fixação da malha. Conclusão: os ensaios clínicos utilizados na composição desse estudo, em sua maioria, tiveram achados pouco relevantes para compor uma preferência pela utilização de malhas cirúrgicas, em comparação à utilização de outros materiais, nos procedimentos de hernioplastia. Além disso, alguns estudos tiveram um período de acompanhamento dos pacientes relativamente curtos, o que prejudicou o nível de evidência e, consequentemente, a confiança nos achados.
A Novel Ig Domain–Containing C-Type Lectin Triggers the Intestine–Hemocyte Axis to Regulate Antibacterial Immunity in Crab
Authors: Zhou Kaimin , Qin Yukai , Song Yu , Zhao Ke , Pan Weijuan , Nan Xingyu , Wang Yue , Wang Qun , Li Weiwei
Published: May 2022

The C-type lectin family with the signature C-type lectin–like domain promotes antibacterial host defense within the animal kingdom. We examined the role of Chinese mitten crab, Eriocheir sinensis (H. Milne-Edwards) (Decapoda: Grapsidae) Ig domain–containing C-type lectin (EsIgLectin), a novel and poorly understood member of the C-type lectin family. EsIgLectin was expressed primarily by both hemocytes (E. sinensis) and intestines, with significantly induced mRNA expression on intestinal or hemolymph bacterial infections. As a soluble protein, both its C-type lectin–like domain and the Ig domain were required for bacterial binding, bacterial agglutination, bacterial growth inhibition, and in vivo bacterial clearance. Polymeric EsIgLectin could be constructed via the disulfide bond in the Ig domain, significantly enhancing EsIgLectin antibacterial activity. EsIgLectin promoted bacterial phagocytosis in an Ig domain–dependent manner in hemocytes, while it controlled microbial homeostasis and protected against bacteria-induced inflammation in the intestine. Protein interaction studies revealed that the EsIgLectin Ig domain bound to the first Ig domain of the polymeric Ig receptor, which was essential for EsIgLectin-induced bacterial phagocytosis. The temporal sequence of cell interactions during intestinal inflammation is only beginning to be understood. In this article, we show that hemocyte-derived EsIgLectin entered the intestinal wall at the later phase of intestinal inflammation. Moreover, EsIgLectin protected the host against intestinal and hemolymph infections in a polymeric Ig receptor–dependent manner. Therefore, the EsIgLectin promoted bacterial clearance and protected against inflammatory disease through an independent or synergistic effect of hemocytes and intestines in invertebrates.
Multi-method sensory approach to describe the effect of microwave-assisted extraction and addition of stems on the mouthfeel sensations of Bonarda wines from Mendoza (Argentina)

Published: May 2022

The Bonarda variety has been used as a base for common red wines due to its contribution to color and low level of astringency as a consequence of its relative low tannin concentration. The use of Microwave- Assisted Extraction (MWE) accelerates the maceration process, improving the diffusion of grape compounds into the must, while the stems addition during maceration/fermentation constitutes a sustainable technological alternative for increasing tannins at no additional cost. The present experimental design consisted of ten treatments (in triplicate), obtained combining both technologies. Two maceration strategies were applied: Control must (C) which was not treated, and must treated with microwavedassisted extraction after grape crushing. These were combined with five Stem-contact conditions (ST): C without ST, 50% ST addition, addition of 50% ST previously treated with MWE, 100% ST addition, and addition of 100% ST previously treated with MWE. The effect of the winemaking technologies on wine mouthfeel sensations was evaluated by different (static and dynamic) sensory methods: Sorting Task; Check-All-That-Applies (CATA) with different textiles as trans-modal references; and Temporal Dominance of Sensations (TDS). CATA evaluation revealed that three of the wine samples differed in their description. These were then dynamically described showing subtle differences in their TDS curves. The sequentiality of dominant sensations showed that the MWE treatment of the grapes and the combination ST with MWE did not modify dramatically mouthfeel sensations in Bonarda wines.
Perioperative Serum Creatinine Change and Delayed Urologic Complications Following Total Laparoscopic Hysterectomy for Benign Indications
Authors: Higami Shota , Tanaka Yusuke , Terada Mikiko , Hosoi Ayako , Koyama Shinsuke , Shiki Yasuhiko
Published: May 2022

Objectives:

The objective of the study was to investigate the association between perioperative serum creatinine change and delayed urologic complications following total laparoscopic hysterectomy (TLH) for benign indications.

Materials and Methods:

A total of 510 cases (503 cases without delayed urologic injuries and 7 cases with delayed urologic injuries) in which TLH was performed for benign indications were retrospectively reviewed. The patient characteristics and surgical outcomes were compared between patients with and without delayed urologic injuries. Laboratory markers (serum creatinine level at the preoperative and postoperative periods, white blood cell [WBC] ratio, and C-reactive protein [CRP] ratio) were analyzed to evaluate the diagnostic value of these laboratory markers.

Results:

There were no statistically significant differences in age, parity, body mass index, the presence of diabetes mellitus, preoperative GnRH agonist use, previous history of abdominal surgery or the performance of adnexal surgery, ASRM score, the presence of cul-de-sac obliteration, operative time, blood loss or weight of the resected specimens between the two groups. The proportions of patients who showed an elevated creatinine level on postoperative day 1 was significantly higher in the delayed urologic injury group (9.9% vs. 57%, P < 0.001). The combination of the three laboratory markers yielded an area under the ROC curve value of 0.75 (95% confidence interval, 0.491–1) in the detection of delayed urologic injuries.

Conclusion:

A change in the serum creatine level over baseline after surgery may indicate the possibility of urologic injuries. The combination of creatinine change and other factors, such as WBC or CRP would be helpful for detecting urologic complications after TLH.
Modified Thermal Balloon Endometrial Ablation for Treatment of Heavy Menstrual Bleeding
Authors: Al-Ibrahim Baraa Lukman Humo , Husaynei Ahmed Jasim Al
Published: May 2022

Objectives:

The objective of this study was to determine the efficacy of modified thermal balloon ablation using Foley's catheter in the treatment of heavy menstrual bleeding (HMB).

Materials and Methods:

Twelve patients with HMB aged 35–55 years underwent modified thermal balloon ablation using Foley's catheter. Patients were selected after complete clinical evaluation and investigations. The procedure was undertaken in the operation theater under general anesthesia/intravenous sedation. Three cycles of modified thermal balloon ablation using Foley's catheter were performed to ablate the endometrium. The time given to each cycle was 7 min. All the cycles were performed in the same setting. The main outcome measures that were studied were reduction in the menstrual flow, the need for further treatment, and relief of dysmenorrhea if present. Outcome measure regarding reduction in menstrual flow was statistically analyzed using Fisher's exact test. Statistical significance was determined at a level of P < 0.05.

Results:

Eighty-two percent of patients experienced a reasonable reduction in menstrual blood flow at 3-month follow-up. Eighteen percent observed no change in bleeding pattern and needed further treatment after failure of the procedure. Forty-two percent of patients complained of minor side effects such as cramp lower abdominal pain and fever. Rupture of balloon during the procedure occurred in only one case (8%).

Conclusion:

Modified thermal balloon ablation with Foley's catheter can be a promising management of HMB in resource-poor settings. It is a cost-effective alternative to the original endometrial ablation techniques.
Benefits of Laparoscopic Surgery for Bleeding Events in Patients with Implantable Left Ventricular Assist Devices during Antithrombotic Therapy
Authors: Nakae Aya , Kodama Michiko , Kobayashi Eiji , Hashimoto Kae , Tominaga Yuji , Kimura Tadashi
Published: May 2022

Hemorrhagic ovarian cysts (HOCs), a common gynecological disease causing intraabdominal bleeding, can be life threatening in patients undergoing antithrombotic therapy, especially those with left ventricular assist device (LVAD) implantation under strong antithrombotic therapy. We encountered three postLVAD implantation cases with intraabdominal bleeding due to suspected HOCs, which required surgery for hemostasis. Such patients are not only at a higher risk of bleeding but also have restrictions in available surgical incision sites to avoid damaging the LVAD driveline located underneath the abdominal wall. Laparoscopic surgery, which can be performed through minute incisions with flexible site selection, may benefit intraabdominal hemorrhage patients with LVADs.

Published: May 2022

AIM:

The study was conducted to assess the changes in bone density before and after performing accelerated orthodontic maxillary canine retraction by microosteoperforations (MOPs).

MATERIALS AND METHODS:

Forty patients (120 cone-beam computed tomography [CBCT] images) within the age group of 15 to 25 years undergoing fixed orthodontic treatment with bilateral maxillary first premolar extraction were enrolled in this study. The right and left sides of the maxillary jaw in the same patients were selected as experimental and control sites. To accelerate the tooth movement, MOPs were performed distal to the canine root in the extraction space under local anesthesia with a miniscrew. Thereafter, the maxillary canine retraction was initiated using a NiTi closed coil spring. The CBCT images were taken and evaluated at the following time intervals: 1 week before MOPs(T0);1 week after MOPs(T1);3 weeks after MOPs(T2).

RESULTS:

A statistically significant reduction in bone density was observed at the center of resistance of canine on the experimental site (after MOPs) at 1 week and 3 weeks (T0-T1 = 0.000,0.115; T1-T2 = 0.0025,0.0117), whereas a statistically non-significant difference was found 1 week before and 3 weeks later in the control group.

CONCLUSION:

Accelerated orthodontics by MOPscan result in a substantial reduction in bone density during canine retraction, leading to an increase in the tooth movement rate, hence lowering the overall orthodontic treatment time.

OBJECTIVE:

To compare the efficacy of Icon resin infiltration and Clinpro XT varnish on remineralization of white spot lesions using a polarized light microscope (PLM).

MATERIALS & METHODS:

Artificial white spot lesions were created on a sample of 40 extracted human premolar teeth by immersing in a demineralizing solution. All samples were randomly allocated to two groups of 20 each; Group A: Icon resin infiltration and Group B: Clinpro XT varnish. Teeth were sectioned along the buccolingual plane using a diamond disc. Specimens were observed under the PLM (4× magnification) at three deepest measurements and their averages were calculated to obtain the mean penetration depth. The data obtained were analyzed using SPSS software (version 22.0). Independent samples t-test and group statistics were used to compare the two groups. In all statistical tests, the significance level was set at 5% (P < 0.05).

RESULTS:

Both Icon resin infiltration and Clinpro XT groups showed a statistically significant difference (P = 0.00) in the penetration depth. Icon resin infiltration group showed a significantly higher penetration depth (24.46 μm) compared to the Clinpro XT group (12.34 μm). Group A showed a greater mean penetration depth (17.07 ± 4.35 μm) when compared to group B (7.68 ± 1.81 μm).

CONCLUSION:

Icon resin infiltration showed a significantly higher penetration depth and is more effective on remineralization of white spot lesions when compared to Clinpro XT varnish.

Published: May 2022

OBJECTIVE:

The study was conducted to evaluate the relationship of various cephalometric skeletal patterns in the vertical and anteroposterior planes with intercanine width in untreated orthodontic patients.

METHOD AND MATERIAL:

This study included dental cast and cephalometric radiographs of 100 patients (69 females and 31 males) of the age range 13 to 33 years. Skeletal parameters including SNA, SNB, SNMP angles were found from lateral cephalometric radiographs. Intercanine widths including upper intercanine widths (UICW) and lower intercanine widths (LICW) were measured by a digital caliper.

RESULTS:

The correlation of intercanine width with SNA, SNB, and SNMP angles was analyzed by applying Pearson correlation coefficient. According to statistical analysis, the only insignificant correlation was analyzed between UICW with SNB and LICW with SN-MP.

CONCLUSIONS:

The overall result showed statistically significant relationship of various cephalometric skeletal patterns in the sagittal and vertical planes with intercanine width.

Published: May 2022

OBJECTIVE:

To investigate the effect of antioxidants on shear bond strength of brackets bonded to bleached enamel with and without titanium dioxide nanoparticles (Lase Peroxide Lite).

MATERIALS AND METHODS:

One hundred and five human maxillary premolars were randomly divided into seven groups (n = 15). Group I served as control, in group II-A bleaching was performed with Opalescent Boost. In group II-B and C, bleaching was performed with Opalescent Boost followed by application of 5% grape seed and 10% green tea extracts, respectively. Group III-A bleaching was performed with Lase Peroxide Lite. Group III-B and III-C bleaching was performed with Lase Peroxide Lite followed by application of 5% grape seed and 10% green tea extracts, respectively. Brackets were bonded with composite resin and cured with light emitting diode (LED) light. Shear bond strength of brackets was tested with a Universal testing machine.

RESULTS:

There was statistically significant difference in the shear bond strength among the seven groups included in the study. There is a statistically significant decrease in shear bond strength in group II-A (8.2 ± 1.6 Mpa), group III-A (8.6 ± 2.1 Mpa) when compared with group I-A (15.9 ± 1.4 Mpa). Among all experimental groups, group II-A showed the lowest mean shear bond-strength values (8.2 ± 1.6 Mpa) (P < 0.005). Group III-C (14.9 ± 2.2 Mpa) has significantly higher shear bond strength.

CONCLUSION:

Bleaching reduced the shear bond strength of brackets below acceptable level while application of grape seed and green tea extracts has recovered the shear bond strength.
MHM bracket design on the path of Dr Andrews of true straight wire technique, prototype study design
Authors: Elkolaly Mohamed Abdelaal , Hasan Hasan S. , Foda Manal Y.
Published: May 2022

OBJECTIVE:

The authors invented an innovation in the bracket design; that targeted to fulfill the aim of Dr. Andrews for a true straight wire technique.

MATERIALS AND METHODS:

The use of the ball and socket design together with the ability to relocate the position of the slot in three dimensions enhances the control and precision of individual teeth.

RESULTS:

The revolutionary bracket eliminated any wire bending in the initial, intermediate or finishing stages of fixed orthodontic treatment. This was achieved together with complete 3D control on individual teeth positions to achieve the finest occlusion for individual patients.

CONCLUSIONS:

That system allowed for a true straight wire mechanics with no wire bending. The design could be used labially or lingually without the need of indirect bonding techniques. Additionally, any adjustments could be performed intraorally with simple pressure.

Published: May 2022

OBJECTIVE:

To compare the effects of comprehensive orthodontic treatment on palatal area, volume, inter-canine and inter-molar width in patients with Unilateral Cleft Lip and Palate (UCLP) using scanned models of the maxillary arch.

DESIGN:

Retrospective cohort study.

SETTING:

Tertiary setting.

PATIENTS:

Two hundred and ten plaster study models of 70 patients with Unilateral Cleft Lip and Palate (Study group SG) and Control Group (n = 70) were scanned using Maestro 3D Dental scanner. The study groupwas further divided into subgroups; Subgroup I: treated with orthodontic treatment only (non-surgical), Subgroup II: patientsmanaged with combined orthodontics and orthognathic surgery (either maxillary advancement or maxillary distraction), Subgroup A: age >14 years and Subgroup B: age <14 years.

INTERVENTIONS:

Comprehensive orthodontic and Orthosurgical treatment

MAIN OUTCOME MEASURES:

Pre- and post-treatment scanned maxillary models of the study group were compared for palatal area and volumeand intercanine and intermolar width. The palatal dimensions of post-treatment scanned models were also compared to that of the control group.

RESULTS:

The Palatal area and volume, intercanine and intermolar width were significantly higher in the post-treatment as compared to pre-treatment study models (P < 0.01). The measurements ofthe maxillary arch were significantly higher in the control group compared to the post-treatment measurements of the study group. The increase in palatal area and volume was greater in Subgroup I and A compared to Subgroup II and B patients, respectively.

CONCLUSION:

The 3-Dimensional palatal dimensions in UCLP group improved after orthodontic treatment but were still not comparable to the normal subjects. The patients with age >14 years showed more improvement in the maxillary arch.

Published: May 2022

Introduction:

Orthodontic appliances complicate daily oral hygiene maintenance and enhance the formation of microbial biofilm on tooth surfaces and orthodontic appliances.

Objective:

This trial was conducted to assess the effect of reminders on oral hygiene of patients during removable orthodontic treatment.

Methods:

In this 2-arm parallel randomized controlled trial, 66 orthodontic patients with removable maxillary appliance were randomly allocated with 1:1 ratio to message reminders and the control group. The patients in the messaging group received one or two message reminders and educational videos weekly during the course of treatment. A single blinded examiner measured the plaque index (PI), gingival index (GI), and dental caries index of patients in both groups at baseline (T0) and one (T1), three (T2), and six (T3) months after the first day of treatment to assess their oral hygiene status during treatment.

Results:

A total of 30 patients in control group and 28 in reminder group completed the study. The PI and GI scores were increased neither in control group nor in message reminder group during T0 and T1, significantly. The PI and GI scores in message reminder group were significantly lower than those in the control group at T2 (PI: P = 0.001, GI: P = 0.003) and T3 (PI: P = 0.024, GI: P = 0.022). Slight significant increasing in the PI and GI score were found during T2 and T3 in message reminder group. Caries index showed no significant difference between two groups during study.

Conclusion:

It seems that reminders can efficiently promote oral hygiene of patients undergoing removable orthodontic treatment.
