Coordination dans un système complexe et concept de polycentricité : quelles perspectives ? Étude du cas des secours d’urgences pré-hospitaliers
Authors: Lenesley Pauline 
Published: March 2023

Étudier la coordination relève d’un défi si l’on souhaite mobiliser l’ensemble des perspectives théoriques (Okhyusen & Bechki, 2009). Nous proposons d’aborder la coordination en mobilisant le concept de polycentricité associé à la diversité institutionnelle d’Ostrom (2005). Cet article s’intéresse à la coordination du secours d’urgence pré hospitalier en pensant la coordination des activités comme une manifestation du travail dans la diversité institutionnelle. Cette diversité d’institutions travaillant de concert avec des mécanismes de résolution de conflits, de décisions partagées caractérise la gouvernance polycentrique. Celle-ci est définie comme une association de centres de décision autonomes mais interdépendants dans le cadre d’un objectif commun. Pour comprendre les systèmes polycentriques nous disposons d’un cadre d’Analyse et Développement Institutionnel, ADI (Ostrom, 2005) rassemblant différentes variables : des éléments institutionnels précis (système de règles, de normes, attributs d’une communauté) pris à un niveau d’analyse individuel (Aligica, 2014). Nous étudions donc la question : en quoi le recours au concept de polycentricité permet de mieux comprendre la coordination d’un système complexe ? Notre cadre théorique est centré sur les différentes perspectives de la coordination et l’apport de la polycentricité. À travers une recherche qualitative compréhensive réalisée à l’aide des principes de l’éthnoméhodologie sur le terrain du secours d’urgence pré-hospitalier nous proposons une approche articulée des différentes théories de la coordination applicable aux systèmes complexes polycentriques à l’aide de la conceptualisation en metacollectif. Nier l’existence de ce méta collectif revient à nier l’écosystème dans lequel toutes les organisations de travail interagissent.

Cet article vise à rendre compte des formes de représentation collective et des niveaux de dialogue social dans l’entreprise « éclatée » où s’exercent des rapports de dépendance via des relations de sous-traitance, de filialisation ou encore dans le cas d’entreprises multi-sites. Il s’appuie sur l’enquête REPONSE 2017 et ses post-enquêtes pour montrer le décalage entre la prédominance des entreprises « éclatées » et le manque d’instances de représentation centralisées. Six monographies font alors apparaître le contraste entre des directions capables de construire leur coordination et des salariés dont la représentation collective se retrouve mise en défaut.
Extension du domaine de la négociation d’entreprise. La négociation d’entreprise sous l’emprise du groupe ?
Authors: Didry Claude , Giordano Denis 
Published: March 2023

Les réformes de 2016 (loi El Khomri) et 2017-2018 (ordonnances et loi de ratification) ont aménagé les notions mêmes de négociation et de convention d’entreprise en ajoutant le niveau du groupe à ceux de l’« entreprise » et de l’établissement. Partant d’une analyse de l’enquête REPONSE montrant le caractère déterminant de ces niveaux de négociation, le retour sur des monographies marquées par la présence d’un groupe conduit à envisager plusieurs configurations, allant de l’action directe du groupe sur la négociation (ou son absence) à une influence moins directe du groupe, associée à une relative autonomie de l’entreprise ou de l’établissement. Si elles présentent le risque de « financiariser la négociation d’entreprise » en l’attachant aux intérêts financiers portés par le groupe, ces réformes laissent donc subsister des espaces pour le déploiement de tactiques syndicales variées.
Des compromis sous hégémonie patronale ? La reconfiguration des usages des dispositifs de la négociation collective dans les établissements français
Authors: Giraud Baptiste , Signoretto Camille , Alfandari François 
Published: March 2023

Comment se reconfigurent les pratiques et les usages des dispositifs de la négociation collective dans un contexte productif et institutionnel en mutations ? De nombreux travaux ont déjà montré les effets liés à la présence de syndicats et à la taille des établissements sur les dynamiques contrastées de la négociation collective. Dans leur prolongement, cet article porte sur l’analyse des liens entre contextes socio-productifs et dynamiques des relations professionnelles. Cette approche permet alors de mieux saisir la manière dont se renforce l’hégémonie patronale sur les pratiques de la négociation collective, sans négliger pour autant la diversité des usages patronaux du dialogue social et des rapports de force que les représentants du personnel sont en capacité de construire dans la production des compromis salariaux.

Published: March 2023

Depuis les lois Auroux de 1982, de nombreuses réformes institutionnelles ont cherché à promouvoir la négociation collective d’entreprise au détriment de la négociation de branche. Les ordonnances de 2017, dites « ordonnances Macron », s’inscrivent dans cette tendance en refondant les domaines de compétences des niveaux de négociation que sont la branche et l’entreprise mais sans laisser à cette première la possibilité d’ouvrir ou non l’espace de la négociation d’entreprise. Dans cet article, nous interrogeons les conséquences de ces réformes en termes de pratiques et de positionnements des acteurs vis-à-vis de la branche en mobilisant de manière croisée une exploitation statistique de l’enquête Relations professionnelles et négociations d’entreprise (REPONSE) et des enquêtes qualitatives menées dans quatre branches (BTP, propreté et services associés, commerce de détail et de gros à prédominance alimentaire et bureaux d’études).
Le basculement du SYSCOHADA vers les normes IAS/IFRS, enjeux et perspectives dans les entités de l’Afrique Subsaharienne : Un mariage ou un divorce ?

Published: March 2023

La littérature sur l’harmonisation comptable reste un sujet mitigé. Elle devient de plus en plus sociale, évolutive au détriment de son prétendu caractère méthodologique. L’objectif est de s’interroger sur les enjeux du couple OHADA-IAS/IFRS pour les entités de l’Afrique Subsaharienne. A partir d’une étude qualitative menée auprès de six entités, les résultats suivants sont obtenus : les normes IAS/IFRS améliorent la qualité de l’information, stimulent l’activité. Par la transparence de l’information rendue possible, l’uniformisation du langage comptable, les marchés financiers connaitront un développement conséquent (Mariage/union). Seulement, le coût de mise en œuvre, la taille des entreprises et la culture constituent des freins (divorce/répudiation).
Après l’effort… que devient le corps ? Ruptures et continuités corporelles chez les ex-sportif•ve•s de haut niveau
Authors: Longchamp Philippe , Braizaz Marion , Tawfik Amal , Toffel Kevin 
Published: March 2023

Si les représentations et pratiques corporelles des sportif·ve·s de haut niveau sont bien connues, on ignore encore largement ce qu’elles deviennent lors de l’après-carrière. Reposant sur une enquête auprès de 30 ex-sportif•ve•s de haut niveau, cet article propose de décrire, au travers de trois portraits, les processus de socialisation constitutifs de rapports au corps spécifiques. Les résultats montrent que les rapports au corps de ces individus peuvent être rapportés, pour partie au moins, à l’articulation entre la socialisation familiale liée à l’origine sociale et la socialisation sportive.
S’engager dans une activité sportive ou physique : des pratiques socialement situées dès l’enfance
Authors: Bertrand Julien , Mennesson Christine 
Published: March 2023

Les pratiques sportives constituent, en France, l’activité de loisir encadré la plus répandue chez les enfants. Le texte présente les résultats d’une enquête menée par questionnaire auprès de 690 parents, dont les enfants, scolarisés en école élémentaire, sont inscrits dans une activité sportive ou physique. Il en ressort que, si la plupart des parents s’accordent sur l’intérêt de ces pratiques, ils ne les envisagent pas de la même manière. La propension au cumul des activités sportives, l’association avec des pratiques culturelles et les rapports à la compétition sont les traits les plus saillants qui distinguent les catégories sociales, leurs usages de ces activités et, in fine, les stratégies éducatives familiales.
Les « curriculums réels » d’une école supérieure en danse contemporaine
Authors: Christe Carole 
Published: March 2023

Les savoirs transmis lors de l’apprentissage de la danse contemporaine sont multiples : ce ne sont pas seulement les techniques physiques qui sont enseignées, mais également de véritables modes de vie. Ainsi, des pratiques de gestion corporelle comme l’alimentation ou les soins s’ajoutent à des interactions relationnelles spécifiques entre membres de l’école. Ces savoir-être permettent aux danseuse•eur•s en formation de se placer dans le champ des arts vivants contemporains grâce à un style de vie distinctif, qui constitue une ressource face aux coûts de la vocation artistique et sportive.
REDUCING CARBON EMISSIONS BY USING PREFABRICATED DECORATION FLOOR SYSTEMS

Published: March 2023

ABSTRACT
The construction industry is one of the three largest carbon emitting industries in the world, accounting for up to thirty percent of global greenhouse gas emissions each year. Since traditional cast-in-situ building operations significantly contribute to these emissions and cannot therefore meet green building requirements, prefabricated buildings have come in to their own as a construction method that effectively reduces carbon emissions. Although studies have been conducted in to reducing carbon emissions by using prefabricated techniques at the building construction stage, none have focused on the reduction of carbon emissions by using prefabricated instead of cast-in-situ decoration systems. This study therefore used a case study in China to evaluate the carbon reduction potential of prefabricated decoration floor systems compared with traditional cast-in-situ decoration floor systems, and to also consider the carbon reduction pathways of four different types of prefabricated floor system from the perspectives of work methods and materials. Since the case study results showed that the carbon emissions reduction of the prefabricated floor system was 69.7%, or 101.5 kg CO2e per cubic meter, it can be concluded that there is a significant carbon reduction potential for using a prefabricated decoration floor system compared with a traditional cast-in-situ decoration floor system. The key contribution of the study is that it provides valuable references for interior decoration practitioners and decision makers when considering ways to reduce carbon emissions through prefabricated decoration floor systems.
Lymphocytic Choriomeningitis Virus Clone 13 Infection Results in CD8 T Cell–Mediated Host Mortality in Diacylglycerol Kinase α–Deficient Mice

Published: March 2023

Abstract
Diacylglycerol is a potent element of intracellular secondary signaling cascades whose production is enhanced by cell-surface receptor agonism and function is regulated by enzymatic degradation by diacylglycerol kinases (DGKs). In T cells, stringent regulation of the activity of this second messenger maintains an appropriate balance between effector function and anergy. In this article, we demonstrate that DGKα is an indispensable regulator of TCR-mediated activation of CD8 T cells in lymphocytic choriomeningitis virus Clone 13 viral infection. In the absence of DGKα, Clone 13 infection in a murine model results in a pathologic, proinflammatory state and a multicellular immunopathologic host death that is predominantly driven by CD8 effector T cells.
Post-operative analgesic efficacy of 0.25% ropivacaine with dexmedetomidine versus dexamethasone as an adjuvant in bilateral superficial cervical plexus block for thyroidectomy under general anaesthesia - A comparative randomized clinical study
Authors: Jain Neena , Rathee Ritesh , Jain Kavita , Garg Deepak K. , Patodi Veena , Khare Arvind 
Published: March 2023

ABSTRACT

Background and Aims:
The bilateral superficial cervical plexus block (BSCPB) is efficacious for post-operative analgesia in thyroid surgeries. We assessed the analgesic efficacy of dexmedetomidine and dexamethasone administered as adjuvants with 0.25 percent ropivacaine in BSCPB for thyroidectomy under general anaesthesia with regard to the duration of analgesia, total amount of rescue analgesic requirement, changes in intra- and post-operative haemodynamic parameters, VAS scores, and adverse events, if any.

Methods:
A prospective double-blind trial was planned with 80 adults undergoing thyroidectomy, randomized into two equal groups and given BSCPB with 20 ml 0.25% ropivacaine with adjuvants as either dexmedetomidine 50mg (group A) or dexamethasone 4mg (group B), 10 ml on each side, after the induction of general anaesthesia. Post-operative pain was monitored using the visual analog scale and the duration of analgesia was measured by time to first rescue analgesia. Post-operative haemodynamics and any adverse events were recorded.

Results:
The mean duration of analgesia was slightly prolonged in group A but statistically non-significant as compared to group B (1037 ± 97 vs. 1004 ± 122 minutes; P0.18). The post-operative median VAS scores and vital parameters were relatively comparable for both groups (P > 0.05) for the first 24h. There was a significant reduction in the incidence of PONV (P < 0.05) in group B.

Conclusion:
Although dexamethasone offers a slight advantage of decreased incidence of PONV, BSCPB using ropivacaine with either dexmedetomidine or dexamethasone as an adjuvant imparted adequate analgesia with stable haemodynamics and may be used as a pre-emptive analgesic technique in thyroid surgeries.
A comparative randomized controlled study of modified 4 in 1 block versus IPACK plus adductor canal block for post-operative analgesia in total knee arthroplasty
Authors: Roy Ritesh , Agarwal Gaurav , Latwal Basant S. , Patel Anamika , Mohta Ankita 
Published: March 2023

Abstract

Background and Aims:
Postoperative analgesia for Total Knee Arthroplasty (TKA) is paramount for early mobilisation and rehabilitation. The newer motor sparing peripheral nerve blocks for analgesia for TKA are 4 in 1 block, modified 4 in 1 block, infiltration between popliteal artery and capsule of the knee (IPACK) block along with adductor canal block (ACB). We hypothesised that Modified 4 in 1 block is as efficient as the already proven technique of combined IPACK and ACB in providing post-operative analgesia to the patients of TKA.

Methods:
Seventy patients fulfilling the inclusion criteria posted for TKA surgery were randomised into two groups: Modified 4 in 1 block group (Group - M) and combined IPACK + ACB group (Group - I). After thorough preoperative evaluation and with mimimum standard monitoring the patients received sub-arachnoid block followed by the desired peripheral nerve block as per the group. After the surgery the visual analog scale (VAS) pain score was compared at 3, 6, 12, 24 hours postoperatively and tabulated.

Results:
The mean pain scores between both the groups was comparable at 3 hours, 6 hours and 24 hours. But at 12 hours after the surgery, VAS was less in Group-M in comparison to Group-I, Haemodynamic parameters were comparable between both the groups. None of the patients in both the groups showed any complications like muscle weakness in the post-operative period.

Conclusion:
Modified 4 in 1 block is a new and novel technique for the TKA surgeries and is comparable with already established combined IPACK+ACB technique for providing adequate postoperative analgesia after TKA.
Ultrasound-guided quadratus lumborum block versus ilioinguinal–iliohypogastric nerve block with wound infiltration for postoperative analgesia in unilateral inguinal surgeries: A randomised controlled trial
Authors: Yadav Manoj , Agrawal Meenu , Bansal Pranav , Prateek  , Garg Mahinder K , Yadav Anita 
Published: March 2023

ABSTRACT

Background and Aims:
Ultrasound (US)-guided quadratus lumborum (QL) block is an abdominal field block that has high efficacy in providing postoperative analgesia for abdominal surgeries. This study was undertaken to compare the US-guided QL block with ilioinguinal–iliohypogastric (IIIH) nerve block and local wound infiltration in unilateral inguinal surgeries, in terms of analgesia and overall patient satisfaction.

Methods:
This randomised controlled trial was conducted in two groups of thirty each. After the completion of surgery under spinal anaesthesia, patients in Group QL received 20 ml of inj. ropivacaine 0.5% while patients in Group IL received 10 ml of inj. ropivacaine 0.5% at the ilioinguinal–iliohypogastric nerve site and 10 ml of inj. ropivacaine 0.5% that was locally infiltrated at the surgical site. Duration of analgesia, Visual Analogue Scale (VAS) score, total requirement of analgesic dosage in the first 24 hours, and patient satisfaction score were compared in both the groups. Statistical analysis was performed using unpaired student’s t test and Chi-squared test with IBM SPSS Statistics version 21 software.

Results:
Duration of analgesia was significantly higher in Group QL (544.83 ± 60.22 min) when compared with Group IL (350.67 ± 67.97 min; P < 0.0001). VAS scores and analgesic requirements were also lower in Group QL. The patient satisfaction score was significantly higher in Group QL (3.93 ± 0.91) when compared to Group IL (3.4 ± 1.0; P < 0.05).

Conclusion:
US-guided QL block significantly prolongs the duration and quality of postoperative analgesia, thereby reducing analgesic consumption and increasing overall patient satisfaction.

Authors: Dey Samarjit , Maurya Indubala , Lohiya Ayush , Arora Prateek , Abdulkader Rizwan Suliankatchi , Chanu Sairem Mangolnganbi 
Published: March 2023

ABSTRACT

Background and Aims:
Flupirtine has been used for various chronic pain conditions, but its utility in the perioperative period as an analgesic is still inconclusive. This systematic review and meta-analysis aimed to assess the efficacy of flupirtine for postoperative pain.

Methods:
PubMed, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) were explored for the randomised controlled trials (RCTs) which compared flupirtine with other analgesic/placebo for perioperative pain in adult patients undergoing surgery. The standardised mean difference (SMD) of pain scores, the need for rescue analgesia and all adverse effects were assessed. Heterogeneity was assessed using Cochrane’s Q statistic test and I2 statistic. Cochrane Collaboration’s tool was used to evaluate the risk of bias and the quality of the RCTs.

Results:
A total of 13 RCTs (including 1,014 patients) that evaluated the use of flupirtine for postoperative pain were included in the study. The pooled SMD of postoperative pain scores revealed that flupirtine and other analgesics were comparable at 0, 6, 12 and 24 hours (P > 0.05), while at 48 hours, flupirtine showed poor pain control (P = 0.04) as compared to other analgesics. There were no significant differences at other time points and on comparison of flupirtine with placebo. The side effect profile was comparable between flupirtine and other analgesics.

Conclusion:
The current evidence suggests that perioperative flupirtine was not superior to other most commonly used analgesics and placebo for the treatment of postoperative pain.
A single-arm prospective interventional study to assess the efficacy of continuous bronchial cuff pressure monitoring to detect the displacement of lung isolation devices in elective thoracic surgeries
Authors: Parab Swapnil Y. , Ranganathan Priya , Shetmahajan Madhavi G. , Majety Sarat C. 
Published: March 2023

ABSTRACT

Background and Aims:
During proximal or distal migration of lung isolation device (LID), the bronchial cuff would move into a wider or narrower portion of the bronchus, leading to a decrease or increase in the cuff pressure, respectively. To test this hypothesis, we conducted a study to find out the efficacy of continuous bronchial cuff pressure (BCP) monitoring for detecting the displacement of LID.

Methods:
A single-arm interventional study was conducted including hundred adult patients undergoing elective thoracic surgeries using a left-sided LID. BCP was monitored in a continuous manner using a pressure transducer connected to the bronchial cuff of the LID. The position of the LID was assessed using a paediatric bronchoscope. Changes in the BCP were noted when the LID was moved intentionally in the left main bronchus (part 1) and during the surgery (part 2). Bronchoscopic confirmation was performed at the end of the surgery to note any uncaptured movement of the LID (part 3).

Results:
During part 1 of the study, BCP consistently decreased on the proximal movement and increased on the distal movement of the LID, although the magnitude of change was not constant. During part 2 of the study, sensitivity, specificity, positive predictive value, negative predictive value and accuracy of continuous BCP monitoring to detect the dislodgement of LIDs (n = 41) during the surgery were 97.6%, 40%, 76.9%, 88.9% and 78.7%, respectively.

Conclusion:
Continuous BCP monitoring is a useful and sensitive method for monitoring the position of left-sided LIDs in limited-resource settings.
Assessment of cellular immunity by CD4+ and CD8+ lymphocyte counts in 2–12-year-old children with iron-deficiency anemia
Authors: Khalale Pratiksha , Patil Bharat Umakant , Ghongade Pravinkumar , Gupta Anupama 
Published: March 2023

Background:
Iron-deficiency anemia (IDA) in children and infants can have long-term adverse consequences on neurodevelopment and behavior, which can be irrevocable in some cases and detrimental to the immune system.

Aim:
The aim of this study was to investigate the role of IDA and its effects on immunity in CD8 and CD4 lymphocytes.

Settings and Designs:
This was a prospective study.

Materials and Methods:
A total of 40 pediatric cases (2–12 years) were first time diagnosed as IDA based on complete blood count (CBC) parameters, peripheral blood smear, and serum ferritin levels. Flow cytometric immune assays were used to determine the number of CD4+ and CD8+ lymphocytes and the ratio of CD4+/CD8+.

Statistical Analysis:
Pearson's correlation coefficient and Students' unpaired t-test were used.

Results:
The difference between the case and control groups in hemoglobin (Hb), red blood cell (RBC) indices, red cell distribution width, RBC count, and serum ferritin is highly significant. A significant linear positive association between CD3+ and CD4+ cell counts and serum ferritin and a significant linear positive correlation between CD4+ cell counts and Hb were observed. However, there was a nonsignificant linear positive association of both parameters, hemoglobin (Hb) and mean corpuscular volume (MCV) with CD3+ cell count, CD4+ cell count, and CD4+/CD8+ cell ratio.

Conclusion:
Iron deficiency does not affect total white blood cell count or differential leukocyte count on routine CBC, but it can alter cellular immunity (CD3+ cell count, CD4+ cell count, and CD4+/CD8+ cell ratio).
