L’acte psychanalytique face à l’expérience post-traumatique de l’explosion de Beyrouth
Authors: Dagher Hoda , Husseini Aline
Published: April 2021

L’explosion du port de Beyrouth, qui est survenue le 4 août 2020 dans une période critique de l’histoire libanaise, a réveillé chez beaucoup de Libanais des blessures anciennes non travaillées. Des survivants de cet évènement traumatique, qui viennent consulter, évoquent, dans leurs récits, une sensation de dépersonnalisation, un mécanisme de survivance face au traumatisme, une espèce de diversion psychique là où le refoulement n’a pas pu opérer. L’évènement traumatique actuel ramène les traces des traumatismes antérieurs, les réactive, les réactualise. Avec ces sujets traumatisés par l’explosion du port de Beyrouth, le travail du psychanalyste consiste, par le biais d’un transfert particulier, en un repérage des besoins du Moi, une contenance du surplus d’excitation qui fait effraction dans la psyché, et en une traduction de leur expérience en contenu assimilable pour la psyché, une production de sens, une activité de symbolisation.
Génération et sélection d’idées dans le processus d’innovation : cas de la méthodologie Delphi dans la logistique 4.0
Authors: Kin Vichara , Rollet Anne , Senkel Marie-Pascale , Jan François
Published: April 2021

La digitalisation et l’hypercompétition participent à un environnement turbulent pour les entreprises qui doivent innover et nouer des relations inter-organisationnelles (RIO) complexes. Dans cette perspective, la « créativité ouverte » et les moyens de génération et sélection d’idées dans le processus d’innovation peuvent offrir une solution. Le recours à des ressources externes, au travers d’une démarche prospective sur la logistique dite « 4.0 », constitue l’objet de cette recherche. L’investigation suit une méthode Delphi-Prodin, peu mobilisée dans la littérature, sur près de huit mois, auprès d’une communauté d’experts. Sur le plan théorique et opérationnel, elle confirme l’intérêt d’un appel à des ressources externes dès l’amont du processus d’innovation. Elle met en avant l’importance des acteurs frontières pour générer et entretenir les liens nécessaires à la création de valeur collective en assumant une partie de la gestion des paradoxes. Sur le plan méthodologique, Delphi-Prodin explicite les étapes de sélection des idées. Codes JEL : O360
Devenir quelqu’un en tuant
Authors: Le Breton David
Published: April 2021

Les djihadistes et les school shooters possèdent un certain nombre de traits en commun : l’impossibilité de s’identifier aux autres, une absence radicale d’empathie, un désir éperdu d’exister enfin dans le regard des autres. Ils ne peuvent se décentrer d’eux-mêmes. Ils incarnent une banalité du mal. Le monde est uniquement leur monde. Leurs victimes ne sont pas susceptibles de les toucher, ils entendent mourir dans un ultime rite de virilité.
Troubles dans la scène punk rock
Authors: Hein Fabien
Published: April 2021

Aux États-Unis, vers le milieu des années 1970, le déclin économique des grands pôles urbains conduit inexorablement à l’abandon des centres-villes. À cette période, les centres-villes sont généralement des zones de relégation ou les plus pauvres, assignés à résidence, côtoient des artistes désargentés. À New York, cette décrépitude urbaine va constituer la toile de fond de la scène musicale punk rock émergente. À cette période, certains artistes semblent s’épanouir dans ce délabrement urbain.
Trajectoires scolaires des enfants roms vivant en bidonvilles. Facteurs d’influence et conséquences
Authors: Grigoras Costel
Published: April 2021

Cet article traite le sujet des trajectoires scolaires des enfants roms qui habitent en bidonvilles en France. On s’intéresse aux différents facteurs d’influence de leurs trajectoires scolaires comme la famille rom et le mode de vie communautaire et l’instabilité de l’habitat informel qu’ils occupent. En même temps, nous cherchons à comprendre quel est l’impact des facteurs institutionnels tels que la pédagogie scolaire employée ou les relations enseignant - élève - parent. En outre, notre regard se pose également sur les conséquences des trajectoires scolaires sur les relations familiales et la communauté rom.

Authors: Estela Scheinvar , Luan Sávio , de Mello Dias Aline
Published: April 2021

Dans le contexte de la société disciplinaire, l’école est structurée sur des bases pénales et morales et exige que les élèves remplissent des conditions préalables en matière d’organisation et d’éducation familiale. À partir des expériences vécues par des enseignants de la ville de Rio de Janeiro, le texte problématise les tensions, l’encadrement et la violence des relations pédagogiques établies, en analysant certains de leurs effets sur la vie quotidienne.
De la différenciation des contextes à la création des écoles fragiles : sources des inégalités d’apprentissage de la petite enfance marocaine
Authors: Ibourk Aomar , Taha Salah Eddine
Published: April 2021

Les travaux sur l’analyse des inégalités d’apprentissage cognitif mettent en lumière entre autres les déterminants sociaux, la qualité de l’environnement de l’école et les caractéristiques des éducatrices. Le présent article s’inscrit dans cette lignée, et ce, en cherchant d’un côté à vérifier l’existence des inégalités d’apprentissage dès le préscolaire. D’un autre, nous allons identifier les sources qui peuvent alimenter potentiellement ces inégalités. Les traits majeurs de notre recherche révèlent que dans le contexte marocain, les enfants appartenant à des sous-groupes socialement différents (urbain vs rural ; genre ; statut socioprofessionnel) ne parviennent pas à tirer les mêmes avantages de l’école. Également, le niveau d’instruction des parents, la qualité de l’environnement, la formation des éducatrices et la taille de classe sont parmi les sources clés des inégalités d’apprentissage en âge préscolaire. La modélisation multiniveaux est appliquée sur les données d’une enquête ad hoc menée auprès de 780 enfants et parents répartis sur plus de 45 établissements préscolaires.
De la transmission des valeurs républicaines à un développement professionnel des enseignants : une étude de cas en Enseignement Moral et Civique (EMC)
Authors: Denny Jean-Luc
Published: April 2021

L’article documente l’activité d’enseignants en situation d’incertitudes professionnelles, car engagés à faire débattre les élèves sur les valeurs en tant qu’objet d’apprentissage-développement dans une visée émancipatoire. La revue de littérature fait état d’enseignants en difficulté avec des tâches visant le développement personnel des élèves en dépit de leur conformité avec les instructions officielles. Défendant une approche compréhensive et transformative de l’activité, nous mobilisons l’expérience dans une visée heuristique. Nous l’abordons sous l’angle des normes et des valeurs par le prisme des outils conceptuels et méthodologiques issus de la démarche ergologique (Schwartz, 2000). Un dispositif longitudinal de recueil de données a été mis en place pendant une année scolaire. Les résultats montrent un développement professionnel marqué tout d’abord par une épreuve de professionnalité qui perturbe les normes du métier. Ensuite nous repérons des transformations par l’activité des normes du métier faisant émerger un obstacle de professionnalité. La mobilisation de gestes contre-intuitifs, à l’opposé des logiques d’agir routinières, est reconnue comme un levier produisant possiblement les effets escomptés sur les élèves. Or, cette configuration nécessite d’aborder la professionnalité comme une dynamique et non comme un état, un fait stable.
Les stratégies d’intervention utilisées par une intervenante dans le cadre d’une démarche préventive des troubles musculosquelettiques et contraintes psychologiques et organisationnelles en milieu hospitalier
Authors: Laneyrie Elsa , Caroly Sandrine , Landry Aurélie
Published: April 2021

Cette recherche a pour objectif d’enrichir les connaissances sur les interventions en organisation ayant pour objet le développement des individus, des collectifs et des organisations. Cet article montre quelles stratégies sont utilisées par un intervenant lors du déploiement d’une intervention afin de la rendre plus efficace. Pour cela, nous avons suivi l’intervention d’une psychologue du travail déployant une démarche préventive appelée ORSOSA (Organisation des Soins et de la Santé des soignants) dans un service de soins. Afin de suivre longitudinalement le processus d’intervention, nous avons utilisé une approche qualitative (journaux de bord, observations, entretiens). L’analyse de nos données permet d’identifier trois principales stratégies utilisées par l’intervenante à des temps distincts de l’intervention visant à : légitimer la pertinence de la démarche, s’adapter au contexte du service de soins, évaluer les résultats de l’intervention. Pour chacune de ces stratégies, les objectifs et modes opératoires ont été décrits.
Pratiques d’ergonomes et dynamiques de transformation dans le cadre de l’expertise SSCT pour les CSE
Authors: Violleau Claire , Dugué Bernard
Published: April 2021

L’expertise CHSCT – désormais expertise pour les CSE en santé, sécurité et conditions de travail – est une forme de pratique de l’ergonomie. Si ce n’est pas la seule discipline à intervenir dans ce cadre, nous supposons néanmoins qu’elle y répond avec certaines spécificités contribuant à la mise en œuvre de transformations. En se basant sur l’étude de plusieurs cas d’intervention dans le cadre d’expertises « projet important », nos analyses démontrent que les transformations sont possibles et multiples : portant sur les relations sociales, les représentations des acteurs, leurs modes d’interactions, mais aussi sur l’intervenant. La posture et l’intelligence situationnelle de ce dernier sont d’ailleurs des éléments clés de la réussite d’une expertise. Ainsi, si ce mode d’intervention est souvent source de critiques en ergonomie, cela vient sans doute de la nature de ses transformations, moins visibles, qui ne sont pas forcément techniques, matérielles ou organisationnelles, mais avant tout profondément sociales.
Analyse du cours de l’action et projet anthropocentré : contributions à la conception de systèmes automatisés
Authors: Antunes Lima Francisco de Paula , Ribeiro Rodrigo , La Guardia Marcelle , Nagem Samira
Published: April 2021

Depuis la décennie de 1950, les échecs de développement de technologies anthropocentriques laissent à penser que les principes généraux de conception ouvrent la voie aux projets sociotechniques bien que ces derniers soient peu opérationnels pour articuler les aspects sociaux, subjectifs et techniques. Cet article démontre comment la théorie du « cours de l’action », qui appartient au champ de l’ergonomie de « l’activité », contribue à rendre cette articulation effective. Sur la base d’un cas d’automation de petites centrales hydro-électriques (PCHs), où des concepts et méthodes de la théorie du cours de l’action ont été utilisés, nous démontrons la nécessité d’une praxéologie empirique afin de traiter les interfaces entre H-H (formation) et H-M (automation), appelées aussi systèmes H-H-M. Du point de vue théorique, les contributions de cet article s’inscrivent au niveau du pôle technologique du Programme de Recherche du Cours de l’Action et, en termes pratiques, il s’agit d’une alerte afin que l’industrie 4.0 ne reproduise pas le mythe de l’usine « sans hommes ».
Modélisation théorique de l’expérience mimétique et cours d’action : analyse de situations de formation en enseignement, santé, et sport
Authors: Leblanc Serge , Bouchot Hélène , Secheppet Mélanie
Published: April 2021

Cet article présente une réflexion théorique pour étudier les processus d’apprentissage-développement à l’œuvre dans des environnements de formation qui confrontent intentionnellement les formés au monde d’autrui. Ces environnements conçus à partir de films du travail réel ou à partir d’observation en situation de simulation et/ou de pratiques accompagnées sollicitent l’articulation de processus mimétiques, réflexifs, projectifs et ludiques. Au cours de la période 2011-2020, trois études relatives à des situations de vidéoformation et/ou de simulation dans des domaines professionnels différents (formation d’enseignants, de sages-femmes, de meneurs d’attelage de chevaux) ont été conduites dans le cadre du programme de recherche empirique dit du « Cours d’action » (Theureau, 2004, 2006) ou d’« anthropologie culturelle enactive » (Theureau, 2015). Une modélisation théorique a été développée pour rendre compte de ces processus de mimésis sociale silencieux et complexes (Wulf, 2007) de mises en relation d’expériences vécues par les acteurs (immersion, imitation, émulation, faire le semblable de, représentation, anticipation). Cette réduction théorique basée sur l’hexatomie de l’unité d’action ouvre des pistes méthodologiques à la fois pour mieux saisir les dimensions implicites de l’activité corporelle et sensible très présentes dans ce rapport au monde d’autrui et, en même temps, permet de mieux comprendre les conditions de performativité de l’action (mimésis comme reprise créative vs mimétisme comme copie du réel).
“L’évaluation ergonomique de dispositifs connectés en santé pour le domicile patient dans le cadre de la chirurgie ambulatoire : Vers un modèle de l’utilisabilité adapté à la e‑santé” [Résumé]
Authors: Chaniaud Noémie
Published: April 2021

Les dispositifs en santé connectée utilisés au domicile du patient sont en pleine expansion. Pourtant, lors de leur conception, des évaluations holistiques de l’utilisabilité – cruciales pour la sécurité du patient – ne sont pas systématiquement standardisées. Afin de pallier ces lacunes, nous proposons dans cette thèse un modèle d’évaluations itératives et cumulatives de l’utilisabilité (HANDLED - Home medicAl coNnected Devices usabiLity Evaluation moDel). Nous avons éprouvé puis validé ce modèle à travers 5 études portant sur la conception et l’évaluation d’un dispositif connecté en santé (Smart Angel) pour le suivi des patients sortant de chirurgie ambulatoire. Ce modèle théorique permet in fine d’assister la conception de dispositifs en santé connectée.
En haine de Sénèque le tragique : formes, enjeux et limites d’un discrédit, de la fin de l’âge classique au romantisme
Authors: Humbert-Mougin Sylvie
Published: April 2021

Cette introduction propose un panorama de la réception européenne de Seneca tragicus, depuis le dernier quart du dix-septième siècle jusqu’à la première moitié du xixe siècle. Alors que le Tragique latin avait représenté un modèle privilégié pour les théoriciens comme pour les poètes tragiques de la première modernité, les deux siècles ici envisagés marquent au contraire un spectaculaire effacement de Sénèque le tragique, que manifestent la décrue du nombre de traductions ainsi que la sévérité du discours critique. Le Théâtre des Grecs du père Brumoy (1730), le Cours de littérature dramatique (1811) d’A.-W. Schlegel, les Études sur les poètes latins de la Décadence (1834) de Désiré Nisard ont joué un rôle décisif dans ce discrédit. La virulence de ces trois textes critiques révèle combien l’appréciation de Sénèque le tragique devient un enjeu sensible, qui mobilise la question passionnelle des « racines » de la culture européenne. Ce discrédit n’empêche pas cependant une forme de résistance plus ou moins souterraine du tragique latin au cours de ces deux siècles de traversée du désert, voire une fascination persistante qui continue de s’exercer jusque sur les détracteurs les plus acharnés. Ce mixte d’attraction et de répulsion forme l’objet des contributions réunies dans ce dossier, qui éclaire une phase mal connue de la longue et complexe histoire de la fortune du tragique latin.

Platform coopetition in two-sided markets
Authors: Raizonville Adrien
Published: April 2021

This paper explores the welfare effects of coopetition between two-sided platforms in the context of a competitive bottleneck, i.e., when participants on one side of the market (the buyers) choose at most one platform (i.e., singlehome), while participants on the other side (the sellers) can be active on both platforms (i.e., multihome). Under coopetition, when platforms set their sellers’ subscription prices cooperatively and buyers’ subscription prices non-cooperatively, platforms internalize that when they reduce their price on the seller side, this will harm the rival platform by making it less attractive to buyers, and through the indirect network effects, to sellers too. Therefore, coopetition leads the platforms to raise their subscription price for sellers compared to the case of full competition. However, as sellers become more valuable under coopetition and buyers exert a positive cross-group network effect on sellers, the competition for buyers is intensified, which leads to a lower price for buyers under coopetition than under competition. Coopetition can increase total surplus compared to full competition if additional participants on the singlehoming side join the market.JEL classification: D43, L13, L86.

Published: April 2021

In present investigation, an attempt was made to optimise the peak stress for paper laminate composite using FRANC2D software. It was observed that the laminate having the triangular geometry supposed to be most appropriate as it has the lowest value of peak stress contour compared to other models like parallel strip, up-down tapered and down-up tapered. The minimum peak stress was observed for the samples having triangular geometry while the maximum was observed for down-up tapered samples. Therefore, the hypothesis adopted to use in-built materials with variables reinforcement area and strip geometry and length in the FRANC2D software to optimize the sample geometry and then apply it to the paper laminate by considering its mechanical properties might be use to optimize the peak stress of paper laminate composite in tensile loading conditions. It was also observed a length of one-quarter of the length of the plane strip, might be the optimum length of the paper laminate samples. However, it feels that, the above model can be further modified considering a more significant mechanical properties as well as different sample geometries.
Laser Photocatalysis of the Chlorophyll Dye Using the Cyclic Voltammetry Method
Authors: Alhasan Huda S.
Published: April 2021

Cyclic voltammetry is a widely used technique in electrochemistry due to its simplicity and large amount of data and information that can be obtained. This study utilises this technique to study chlorophyll a and total chlorophyll (Tchl) alongside a laser light to induce photosynthesis. No oxidative peak was observed, regardless of the solution pH in either a dark or light environment when using a solution with an electrolyte of tetrabutylammonium perchlorate (TBAP) in both dichloromethane (DCM) and acetonitrile (MeCN), whereas in a solution of aqueous HCl a small anodic peak was observed. The concentration of the droplet of Tchl pigment on the surface of macro glassy carbon electrode (GCE) was increased, which resulted in a similar trend and the oxidation peak was observed to be slightly larger when in the presence of light. It was observed that the filtered solution of Tchl pigment produced a weaker signal than the unfiltered solution and there were slightly reduced oxidative peak currents when the concentration of VK1 was increased. were no observed changes in the peak charges or currents over a wide potential range (0.0, 0.2, 0.4, 0.6 and 0.8 V) in the presence or absence of light by using coulometry and amperometry methods, therefore, more information on the 3-D formation is required for the photoreduction processes.
A Review on Chemical Mechanical Planarization of Barrier Layer Metals
Authors: Shukla Arpita , Victoria S. Noyel , Manivannan R.
Published: April 2021

Chemical mechanical planarization (CMP) is recognized to be one of the finest polishing techniques which provides a smooth and globally planarized metal surface in the field of semiconductor device manufacturing. This process aids in material removal followed with a well finished and planarized surface by a combination of both chemical and mechanical action imparted by oxidizer and abrasive particle respectively. Semiconductor device manufacturing process is an amalgamation of two sub processes i.e. front end of line (FEOL) and back end of line (BEOL). The whole process consists of different segments comprising of several types of material that need to be planarized. The slurry components play an imperative role in metal CMP. It comprises abrasive, oxidizer, and several additives such as complexing agent, corrosion inhibitor, pH adjustor, slurry stabilizer, etc. and each imparts diverse impact on the material needs to be polished. One of the main topics of concern in this area is the removal rate selectivity of interconnects metal to the barrier layer metal. Thus, the reported review work efforts to emphasize the planarization of barrier layer materials, the various key ingredients employed in metal CMP and removal rate selectivity between interconnects and barrier layer metal.
Nesting of the Spotless Starling, Sturnus unicolor, on the island of Favignana (Aegadian Islands, Sicily)
Authors: Lo Valvo Mario , Pieri Domenico
Published: April 2021

The presence of the Spotless Starling in Sicily was reported for the first time at the beginning of the XIX century, although the first nests for the province of Trapani are reported almost at the end of the XX century. As a breeder, the Spotless Starling remained absent from all the circumsicilian islands until the first report for the island of Pantelleria, in 2012. In 2020, the nest of Spotless Starling was observed on the island of Favignana, within a hole on an antenna. The couple fed the chicks with Ligia italica crustacean isopod of the family Ligiidae. The nesting on the island of Favignana confirms the continuous expansion of the species in Sicily.

The Saudi Pediatric Pulmonology Association (SPPA) is a subsidiary of the Saudi Thoracic Society (STS), which consists of a group of Saudi experts with well-respected academic and clinical backgrounds in the fields of asthma and other respiratory diseases. The SPPA Expert Panel realized the need to draw up a clear, simple to understand, and easy to use guidance regarding the application of different aerosol therapies in respiratory diseases in children, due to the high prevalence and high economic burden of these diseases in Saudi Arabia. This statement was developed based on the available literature, new evidence, and experts' practice to come up with such consensuses about the usage of different aerosol therapies for the management of respiratory diseases in children (asthma and nonasthma) in different patient settings, including outpatient, emergency room, intensive care unit, and inpatient settings. For this purpose, SPPA has initiated and formed a national committee which consists of experts from concerned specialties (pediatric pulmonology, pediatric emergency, clinical pharmacology, pediatric respiratory therapy, as well as pediatric and neonatal intensive care). These committee members are from different healthcare sectors in Saudi Arabia (Ministry of Health, Ministry of Defence, Ministry of Education, and private healthcare sector). In addition to that, this committee is representing different regions in Saudi Arabia (Eastern, Central, and Western region). The subject was divided into several topics which were then assigned to at least two experts. The authors searched the literature according to their own strategies without central literature review. To achieve consensus, draft reports and recommendations were reviewed and voted on by the whole panel.
Peri-Operative and Anesthesia Considerations for Patient Recovered from COVID-19 Scheduled for Radical Cancer Surgery
Authors: Singh Daljeet , Hariharan Uma , Joshi Anumeha , Nandan Ganesh
Published: April 2021

The current COVID-19 pandemic has affected the health-care system worldwide. While there is a plenty of literature in recent times regarding the anesthetic management of COVID-positive patients for various surgeries, there is a paucity of publications on the concerns and anesthetic implications of COVID-19 recovered patients, posted for major oncology surgery. We, hereby, present a geriatric case of post-COVID-19 recovered patient posted for radical cystectomy following chemotherapy. These patients are immunosuppressed due to cancer per se as well as because of concurrent chemotherapy, and hence, they may have a stormy course of COVID-19 infection. Since, COVID-19 affects multiple organs, preoperative evaluation must thoroughly investigate all the systems. Anesthetic management and operating theatre preparedness for such cases is discussed in brief.
Knowledge and Awareness of Labor Analgesia Services Available in Our Tertiary Hospital among the Pregnant Women
Authors: Chandrashekaraiah Mahesh Madhugiri , Koshy Lena , Hakema Samah Haidar , Ahmed Sadiya S. , Mahammad Shakeel B. , Ibrahim Nusiba
Published: April 2021

Background:

Knowledge regarding labor analgesia is poor among the pregnant women. This hinders them from utilizing the services in centers where it is available. In this study, we tried to analyze the awareness and knowledge of the antenatal women and their beliefs regarding labor analgesia.

Patients and Methods:

This prospective, observational study done in antenatal clinic for 1 month. Antenatal women who attended the clinic voluntarily filled the semi-structured questionnaire after the written and informed consent.

Results:

A total of 170 women filled the questionnaire out of 1099 antenatal visits. 68.8% were multipara and 50.58% had previous vaginal delivery. 63.3% study population had prior information of labor analgesia; while only 42.6% had information that labor analgesia services are available in our hospital (P = 0.002). Age, education, and parity were considered as predictors; however, parity is the only predictor for knowledge of labor analgesia odds ratio = 2.368 (95% CI–1.24, 4.51; P = 0.009). Majority (60.23%) of the study sample believe that there is no effective method of pain relief during labor. Binary logistic regression and Chi-square test used for the statistical analysis.

Conclusion:

Antenatal women still believe that there is no effective method of labor analgesia. Women prefer obstetrician advice for getting information regarding labor analgesia. In our study, the level of education has no impact on awareness of labor analgesia. Only parity is a predictive factor for knowledge of labor analgesia.
Tourniquet Complications in an Upper Extremity Orthopedic Surgery Patients
Authors: Senapathi Tjokorda Gde Agung , Jobul Ivan Christianto , Suarjaya I Putu Pramana , Pradhana Adinda Putra , Ryalino Christopher
Published: April 2021

An arterial tourniquet is a pneumatic device consisting of an inflated cuff connected to a supply of compressed gas. The most common use for these tourniquets is in surgical procedures on the extremities, where the tourniquet is very useful in optimizing the operating conditions by creating a bloodless surgical field. However, the exsanguination process followed by ischemia will result in physiological problems with local and systemic consequences. The patient in the case to be discussed is a 54-year-old woman with a diagnosis of implant loosening et causa nonunion left Montegia fracture who was scheduled for implant revision surgery. From these cases, it is possible that the patient experienced tourniquet-induced hypertension, which is one of the systemic complications that can arise due to the use of the tourniquet. It is said that tourniquet-induced hypertension is often difficult to control and is resistant so it is difficult to lower it. Emerging hypertension may not present a significant problem in young, noncomorbid patients, but in these patients with comorbid of hypertensive heart disease (HHD), elevated blood pressure can be very detrimental. Preoperative ketamine, clonidine, or lidocaine has been used to prevent tourniquet pain, which can lead to increased arterial pressure that is difficult to control. The anesthetist is also obliged to monitor the duration and pressure applied by the tourniquet so that it is not excessive so that detrimental complications can be prevented.

Published: April 2021

Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by vascular thrombosis or pregnancy complications with the presence of antiphospholipid antibodies. It is a rare disease affecting 40–50/100,000 population yet responsible for 10%–15% of recurrent pregnancy loss. Diagnosis requires at least one clinical and one laboratory criteria to be met. Perioperative management in obstetric APS underwent cesarean section stressed on the management of anticoagulation and proper choice of anesthesia technique. We report the case of a 21-years-old woman, 39 weeks pregnant, diagnosed with APS since the 8th week of gestation. She had two previous miscarriages and an elevated level of anticardiolipin antibody (aCL IgG: 21 GPL U/ml) with normal aCL IgM and lupus anticoagulant. She was treated with a prophylactic dose of low-molecular-weight heparin (0.4 IU subcutaneous enoxaparin) and oral aspirin 80 mg daily. She presented to the obstetric department and scheduled for an urgent cesarean section. Enoxaparin was held, and the surgery was done with spinal anesthesia. Anticoagulation resumed 12 h after surgery. No complications on the mother and baby were found after 3 days of observation.
Cisatracurium Versus Atracurium for Abdominal Surgeries Regarding Condition of Intubation and Hemodynamic Effect
Authors: Ranjan Rahul , Alam Mohammad Faseehullah , Avinash Raja
Published: April 2021

Background:

Neuromuscular-blocking drugs block neuromuscular transmission, causing paralysis of the affected skeletal muscles. In clinical use, neuromuscular block is used adjunctively to anesthesia to produce paralysis, first to paralyze the vocal cords, and permit intubation of the trachea, and second to optimize the surgical field by inhibiting spontaneous ventilation, and causing relaxation of skeletal muscles.

Patients and Methods:

This was a prospective, randomized study registered in Clinical Trials Registry of India (CTRI/2019/04/018580). We included 100 patients divided into two groups of 50 each. Group A received atracurium (0.5 mg/kg), whereas Group B received cisatracurium (0.15 mg/kg). Efficacy of both the drugs was compared in terms of onset of action, duration of action, duration of recovery, hemodynamic conditions during and after intubation, and signs of histamine release in both the drugs.

Results:

Mean duration of 25% recovery from the reversal in the atracurium group was 32.4 ± 1.90 min which was significantly less as compared to 49.46 ± 1.86 min of cisatracurium group (P < 0.001). The mean duration of recovery from the reversal in cisatracurium group was 2.18 ± 0.82 min which was significantly more as compared to 1.8 ± 0.75 min of atracurium group (P = 0.02).

Conclusion:

Cisatracurium in a dose of 0.15 mg/kg had a faster onset and duration of action than atracurium 0.5 mg/kg. At this dose, cisatracurium provides optimal intubating condition, rapid neuromuscular blocking with longer duration of action, stable hemodynamic status, no signs of histamine release clinically, and without any residual muscle paralysis compared to atracurium.
Quality of life after giant hiatus hernia repair
Authors: Date Akshay R. , Goh Yan Mei , Goh Yan Li , Rajendran Ilayaraja , Date Ravindra S.
Published: April 2021

Background:

Elective surgery is the treatment of choice for symptomatic giant hiatus hernia (GHH), and quality of life (QoL) has become an important outcome measure following surgery. The aim of this study is to review the literature assessing QoL following repair of GHH.

Methodology:

A systematic literature search was performed by two reviewers independently to identify original studies evaluating QoL outcomes after GHH surgery. MeSH terms such as paraoesophageal; hiatus hernia; giant hiatus hernia and quality of life were used in the initial search. Original studies in English language using validated questionnaires on humans were included. Review articles, conference abstracts and case reports and studies with duplicate data were excluded.

Results:

Two hundred and eight articles were identified on initial search, of which 38 studies (4404 patients) were included. Studies showed a significant heterogeneity in QoL assessment tools, surgical techniques and follow-up methods. All studies assessing both pre-operative and post-operative QoL (n = 31) reported improved QoL on follow-up after surgical repair of GHH. Improvement in QoL following GHH repair was not affected by patient age, surgical technique or the use of mesh. Recurrence of GHH after surgery may, however, adversely impact QoL.

Conclusion:

Surgical repair of GHH improved QoL scores in all the 38 studies. The impact of recurrence on QoL needs further assessment. The authors also recommend uniform reporting of surgical outcomes in future studies.
A different suturing method of the duct-to-mucosa pancreaticojejunostomy for the normal pancreatic duct in laparoscopic pancreaticoduodenectomy
Authors: Wang Ziyao , Wang Xin , Ke Nengwen
Published: April 2021

Although laparoscopic pancreaticoduodenectomy (LPD) is safe and widely used in clinical practice, pancreaticojejunostomy is still one of the most challenging parts of LPD surgery. We introduce a simpler method of pancreaticoenterostomy which reduces the technical complexity and produces acceptable results.

Authors: Ismail Samina , Hameed Malika
Published: April 2021

Background and Objective:

In low and middle-income countries (LMICs), general anesthesia for cesarean section has shown to increase the odds of maternal mortality. Use of regional anesthesia for cesarean section is an indicator for safe practice of anesthesia; therefore, this study aims to evaluate the current practice of use of regional anesthesia and its failure rate for cesarean section. The current practice is analyzed in the light of previously published data from the same institution of LMIC.

Methods:

After hospital ethics committee approval, this prospective cross-sectional study was performed from January 1 to June 30, 2019. Prospective data collected on predesigned form included technique of anesthesia employed for different category of cesarean section, failure of regional anesthesia, and other related data. The cesarean section rate and trends of technique of anesthesia over last 10 years were collected from hospital record system.

Results:

Compared to the published data from the year 2012 from the same institution, the results from this prospective data have shown an increase rate of cesarean section rate from 31% to 52% with an overall decline in the use of general anesthesia from 49% to 12.3%. In addition, rate of regional anesthesia for category 1–3 cesarean section has increased from 46.4% to 79.8% and for category 1 from 37.1% to 63.4%. Decline in failure rate of regional technique was observed from 6.7% to 2.4%.

Conclusion:

Assessing and analyzing practices helps in taking initiative to implement safe practices which are needed to achieve the target for best practice.

Development of Fast Atrial Fibrillation in an Awake Parturient Undergoing Elective Caesarean Section
Authors: Baxter Gregg James
Published: April 2021

A 25 year-old, fit and well, G2P1 woman presented for elective caesarean section under spinal anaesthesia for breech presentation. Following a straight forward spinal anaesthetic and initial progression of surgery, the patient developed atrial fibrillation with a fast ventricular response shortly after delivery and bolus of 5 units of oxytocin. Attempts to restore sinus rhythm with pharmacological methods were unsuccessful and ultimately the patient required electrical cardioversion. An RSI was performed as the patient was still within the first 48 hours post-delivery. Upon laryngoscopy, the patient reverted to sinus rhythm without the need for DC cardioversion. After a short stay in the hospital, the patient was discharged with outpatient ECHO and follow-up awaited. Blood, including thyroid function tests, were unremarkable pre-, intra- and post-operatively. This case report highlights the rarity of development of AF whilst also covering the management of this arrhythmia in the context of the awake parturient.
Retinal artery occlusion following cosmetic injection of poly-L-lactic acid
Authors: Wu Chao-Wei , Wu Horng-Jiun
Published: April 2021

Ophthalmic vascular occlusion is an infrequent but devastating complication following cosmetic facial filler injection. We report a case of developing retinal artery occlusion after poly-L-lactic acid (PLLA) injection. A 49-year-old woman with multiple chronic diseases experienced sudden central visual loss and severe ocular pain in the right eye immediately after PLLA injection in the temporal region. Her best-corrected visual acuity in the right eye dropped from 20/20 to 20/200. Fundus photography showed marked optic disc edema and localized retinal whitening in the territory of the blocked vessels. Spectral-domain optical coherence tomography revealed localized hyperreflectivity of the inner retina and retinal edema. Fluorescein angiography showed delayed filling of the retinal arteries and absence of retinal perfusion in the affected areas. Despite prompt aggressive management of the condition with ocular massage, topical brimonidine eyedrops, and hyperbaric oxygen therapy, the patient suffered permanent visual loss due to optic atrophy. Among all the subcutaneous filler materials, PLLA has not been a common cause of vascular complications, especially when injected in the temporal region, as this area has not been considered dangerous in the previous literature. Practitioners should be aware of the risk of visual loss, and extra care should be given on those who originally have a higher risk for vascular complications.
Access to big data as a remedy in big tech
Authors: Dadson Nick , Snoddy Iain , White Joshua
Published: April 2021

‘Big data’ and ‘big tech’ have become central topics in recent antitrust debate and regulation. For example, the Competition and Markets Authority (CMA) recently published a report on online platforms, expressing concerns that the major platforms like Google are now protected from competition by such strong incumbency advantages. Underlying the CMA's theory of harm is the essential facility theory of antitrust, under which Google's ability to control access to its click-and-query data is seen as preventing its rivals from competing effectively. EU jurisprudence has identified three criteria to determine whether data are an essential facility and whether access should be mandated. First, the data must be indispensable to compete in the market. Secondly, absent data sharing, technical improvements by competitors must be hampered or precluded. Thirdly, there must be no objective justification to refuse competitors access to the data. It is difficult to reconcile the authorities’ concerns with Google's click-and-query data with these criteria, however. Actual and potential alternatives exist; Google's competitors have been innovating in the search market for more than a decade; and there are objective reasons to limit data access, including threats to innovation and privacy concerns.
EU merger control: life without the UK – Brexit and beyond
Authors: Bushell Gavin , Whyte Emma
Published: April 2021

Since 1 January 2021, the ‘one-stop shop’ principle under the EU Merger Regulation (EUMR) no longer applies to the UK, and UK turnover is no longer relevant for determining whether a merger satisfies the EUMR jurisdictional thresholds. Merger control analysis will now need to factor in possible interactions with both the European Commission (Commission) and the Competition and Markets Authority (CMA). The two regimes have different procedures, timelines and substantive tests, which will impact on deal planning and strategy. Dual reviews by both authorities will likely lead to an additional burden on merging parties as well as a risk of a deal being cleared by the Commission but blocked by the CMA, or vice-versa. This article assesses the procedural and practical implications of these changes and highlights some of the key risks businesses may face in merger control looking ahead.
Algorithms and competition: the latest theory and evidence
Authors: Descamps Ambroise , Klein Timo , Shier Gareth
Published: April 2021

In the modern economy, algorithms influence many aspects of our lives, from how much we pay for groceries and what adverts we see, to the decisions taken by health professionals. As is true with all new technologies, algorithms bring new economic opportunities and make our lives easier, but they also bring new challenges. Indeed, many competition authorities have voiced their concerns that under certain circumstances algorithms may harm consumers, lead to exclusion of some competitors and may even enable firms (knowingly or otherwise) to avoid competitive pressure and collude. In this article, we explain how algorithms work and what potential benefits and harms they bring to competition.
Ảnh hưởng của chất lượng báo cáo tài chính và nợ ngắn hạn đến hiệu quả đầu tư của các doanh nghiệp niêm yết tại sở giao dịch chứng khoán Thành phố Hồ Chí Minh (HOSE)
Authors: Anh Hoàng Thị Phương , Hà Vũ Minh , Hồng Nguyễn Thị Thu
Published: April 2021

Mục tiêu của bài nghiên cứu là xem xét ảnh hưởng của chất lượng báo cáo tài chính và nợ ngắn hạn đối với hiệu quả đầu tư trên một mẫu gồm 200 doanh nghiệp phi tài chính được niêm yết tại HOSE trong giai đoạn từ năm 2009-2015. Kết quả nghiên cứu cho thấy: việc tăng chất lượng báo cáo tài chính và mức nợ ngắn hạn sẽ góp phần làm gia tăng hiệu quả đầu tư cho các doanh nghiệp. Bên cạnh đó, bài nghiên cứu cũng tìm thấy được mối quan hệ thay thế giữa chất lượng báo cáo tài chính và nợ ngắn hạn trong việc nâng cao hiệu quả đầu tư: doanh nghiệp sử dụng nợ ngắn hạn ít hơn (nhiều hơn) thì mức độ tác động của chất lượng báo cáo tài chính lên hiệu quả đầu tư sẽ cao hơn (thấp hơn).

Quan hệ giữa bất bình đẳng thu nhập và tăng trưởng kinh tế đã thu hút nhiều sự chú ý của các nhà nghiên cứu kinh tế và cơ quan hoạch định chính sách. Tuy nhiên, bất bình đẳng thu nhập theo giới tính vẫn chưa dành được nhiều sự quan tâm, đặc biệt trong bối cảnh của các quốc gia mới nổi như Việt Nam. Nghiên cứu này được thực hiện để đánh giá và lượng hóa tác động của bất bình đẳng thu nhập theo giới lên tăng trưởng kinh tế địa phương cho 63 Tỉnh/thành trong giai đoạn 2004-2014, thời điểm mới nhất dữ liệu nghiên cứu có được từ cuộc khảo sát của Tổng cục Thống kê. Trong nghiên cứu này, bất bình đẳng thu nhập theo giới tính được đo lường bởi hai chỉ số khác nhau: (i) Chỉ số Gini; và (ii) Chỉ số Theil. Kết quả nghiên cứu chỉ ra rằng trong khi bất bình đẳng thu nhập theo nam giới có tác động và tác động cùng chiều đến tăng trưởng kinh tế, bất bình đẳng thu nhập theo nữ giới lại có tác động ngược chiều đến tăng trưởng kinh tế địa phương tại Việt Nam trong thời gian vừa qua.
