Fonctions et processus psychiques d’un groupe à médiation artistique avec des hommes migrants
Authors: Fréard Anne , Feldman Marion 
Published: April 2022

Cet article livre des éléments de compréhension sur les spécificités de la dynamique psychique groupale d’un atelier thérapeutique à médiation artistique avec des hommes migrants. Pendant neuf mois, à raison d’une heure et demi hebdomadaire, le « groupe dessinature » – comme le baptisera l’un des hommes du groupe –, nous fait voyager dans une clinique riche et passionnante. Le verbatim et les créations que nous avons recueillis nous renseignent sur les principaux enjeux d’un tel dispositif. Nous proposons, ainsi, de soulever les points de chiasme qui se révèlent entre la problématique groupale et individuelle de l’histoire migratoire et culturelle de chacun. Précisément, le groupe semble réactualiser des conflits psychiques du deuil, de l’exil, de la rupture du « cadre culturel » contenant, ainsi que les défenses qui y sont associées. La médiation artistique permet d’observer ces mouvements psychiques convoqués par la situation groupale tout en même temps qu’elle contient la possibilité de les symboliser.

Au vu de la pression démographique et des transformations technologiques de la production, l’Inde est particulièrement confrontée au défi de l’emploi. Si l’Organisation internationale du travail (OIT) a commencé à interroger l’impact de l’automatisation sur la division mondiale du travail, elle l’a fait à travers le prisme d’un emploi décent ou « typique », alors que le focus devrait être mis sur le potentiel d’égalité et de justice des emplois futurs.
Roger Nols: a mayor to be forgotten?
Authors: Jaumain Serge , Vaesen Joost 
Published: April 2022

Faut-il déboulonner le buste de Roger Nols ? La question fait aujourd’hui débat. Interrogeant les raisons pour lesquelles la représentation et le souvenir de l’ancien bourgmestre de Schaerbeek paraissent si encombrants dans l’espace public, cet article souligne la nécessité́ de replacer les évènements contestés dans un contexte historique plus large. Il met en garde contre une critique centrée sur la seule personne de Roger Nols qui pourrait exonérer à bon compte celles et ceux qui ont soutenu ouvertement ou dans le secret des urnes, des discours et politiques racistes et xénophobes, tant à Schaerbeek que dans d’autres communes de la capitale. Cette réflexion permet de discuter les risques du « présentisme », c’est-à-dire l’utilisation du passé en fonction d’objectifs politiques actuels sans tenir compte de la réalité́ historique. Elle montre qu’il ne revient pas aux historiens de prendre une décision sur l’avenir d’un tel buste mais qu’ils ont par contre un rôle essentiel à jouer pour documenter le contexte dans lequel l’action de la personne contestée s’est inscrite.

Introduction: Patients with sepsis or severe sepsis usually present to the Emergency Department (ED). The overall mortality rate for patients admitted with severe sepsis is 35% - approximately five times higher than that of ST-elevation myocardial infarction. Prompt recognition and treatment are essential to improve survival. Our aim was to study the time to recognition, identify aetiology, and obtain antibiotic sensitivity patterns and outcome of patients presenting with suspected sepsis.
Methodology: A prospective observational study including all patients suspected of having sepsis was carried out from July 1, 2016, to June 30, 2017, at the Emergency Department (ED) of the Provincial General Hospital Kurunegala, Sri Lanka. The study instrument was a data sheet comprising of the surviving sepsis guidelines (Sepsis 2) of the United Kingdom and demographics and background information from patient records. All the patients were followed up for one month.
Results: One hundred and four patients (Age:61 ±17, 54.8% males) were studied. Blood culture results were available in 94 patients (90.4%) of which 19 (20%) were positive. The most common organisms identified were coagulase-negative Staphylococcus (CoNS) (42%) and Escherichia coli (42%). Door to blood culture time was 38.6 ± 26.7 minutes with 98% having blood cultures taken within 45 minutes of admission. Door to antibiotic time was 43.3 ±27.2 minutes. The most common primary foci of infection were pneumonia (34.6%) and cellulitis (28.8%). All CoNS were sensitive to teicoplanin and vancomycin, while all Escherichia coli isolates were sensitive to meropenem. The median (IQR) duration of hospital stay was 6 (3 to 9.1) days.
The in-hospital mortality was 30 (28.9%) and 30-day mortality was 36 (34.6%). There was no statistical significance regarding mortality among blood culture positive and negative patients.
Conclusion: The sepsis bundle had been activated within 45 minutes in most of our patients. The outcome of sepsis at our hospital is better than data published from other centres around the world.

Published: April 2022

Background:
The aim of this study was to compare the effect of adding oral clonidine to standard treatments on pain intensity in patients with acute renal colic.

Materials and Methods:
This is a randomized clinical trial that was performed in 2020 in Isfahan. The study population consisted of 200 patients with renal colic. Pain of the patients was assessed using Visual Analog Scale. Patients were then randomized into 4 groups of 50 patients. Group A received 0.1 mg/kg morphine and clonidine tablets (0.2 mg). Group B received morphine and placebo. Group C received 30 mg ketorolac and clonidine tablets. Group D received 30 mg ketorolac and placebo tablets. Pain of patients was assessed. 0.05 mg/kg morphine was administered and repeated every 40 min if the pain was not reduced.

Results:
Our data showed that there was a significant difference between pains of patient by the time of admission in groups (P = 0.04). However, no significant differences were observed between pains of patients in different measuring times (P > 0.05). Using general linear model, we showed that the decreases in pain scores of each group were significant (P < 0.05) but there were no significant differences in pains of patients in different measuring times (P > 0.05). Our data showed that Group A and Group C had lowest frequencies of morphine administrations while Groups B and D had the highest frequencies (P < 0.001).

Conclusion:
We showed that administration of clonidine in patients with renal colic resulted in better pain control and lower morphine injections.

Published: April 2022

Background:
One of the basic practices in the field of waste management is the collection and treatment of leachate. Leachate from municipal waste due to high chemical oxygen demand (COD) and dark color is a potential pollutant of the environment, which causes a lot of problems in the absence of treatment and direct discharge to the environment. This study aimed to determine the efficiency of ultrasonic process in combination with coagulation and flocculation process using sodium ferrate in COD and color reduction.

Materials and Methods:
In this experimental study, all experiments were performed in batch conditions and with changing process variables such as pH and sonication time, and the effect of three parameters, including ultrasonic reaction time (15, 30, and 45 min), pH (2, 4, 5/5, and 7), and coagulant dosage (from 1 to 150 g/l) on the COD reduction and color removal, was evaluated. Coagulant concentration and then the removal efficiency of COD and color were analyzed by ANOVA using SPSS 18.

Results:
The COD reduction and color removal were 87.05% and 88.6% in optimal condition (using 120 g/L of sodium ferrate at pH 5.5), with coagulation/flocculation, after ultrasound (15 min). Ultrasound (15 min) + sodium ferrate (without coagulation/flocculation) achieved 46.25% of COD reduction and 90.35% of color elimination, whereas the ultrasonic process alone allowed removing the COD and color in the leachate by less than 50%.

Conclusion:
The results indicate that C–F followed by ultrasonic can be used to efficiently reduce the organic matter and color from municipal waste leachate, and it would be an ideal option for leachate treatment.

ABSTRACT
This study aimed to assess the role of prostate-specific antigen density (PSAD) and negative multiparametric magnetic resonance imaging (mpMRI) in predicting prostate cancer for biopsy-naïve men based on a large cohort of the Chinese population. From a prostate biopsy database between March 2017 and July 2021, we retrospectively identified 240 biopsy-naïve patients with negative prebiopsy mpMRI (Prostate Imaging Reporting and Data System version 2 [PI-RADS v2] score <3). Logistic regression analysis was performed to select the potential predictors for clinically significant prostate cancer (csPCa). Receiver operating characteristic (ROC) curve analysis and area under the ROC curve (AUC) were performed to assess the diagnostic accuracy. The negative predictive values of mpMRI in excluding any cancer and csPCa were 83.8% (201/240) and 90.8% (218/240), respectively. ROC curve analysis indicated that PSAD was the most promising predictor, with an AUC value of 0.786 (95% confidence interval [CI]: 0.699–0.874), and multiparametric logistic regression analysis confirmed that higher PSAD remained a significant marker for predicting csPCa (odds ratio [OR]: 10.99, 95% CI: 2.75–44.02, P < 0.001). Combining negative mpMRI and PSAD below 0.20 ng ml−2 obviously increased the predictive value in excluding PCa (91.0%, 101/111) or csPCa (100.0%, 111/111). If a PSAD below 0.20 ng ml−2 was set as the criterion to omit biopsy, nearly 46.3% of patients (463 per 1000) with negative mpMRI could safely avoid unnecessary biopsy, with approximately 4.2% of patients (42 per 1000) at risk of missed diagnosis of PCa and no patients with csPCa missed. A PI-RADS v2 score <3 and a PSAD <0.20 ng ml−2 could be potential criteria for the Chinese population to omit prompt biopsy safely.

Authors: Hoseini Maryam , Malekipour Mohammad Reza , Shirani Farzaneh 
Published: April 2022

Background:
This study investigated the impact of sonic vibration on the root dentin-glass fiber post bond strength using two resin cements.

Materials and methods:
Forty single-canal teeth were randomly divided into four groups (n = 10): Theracem self-adhesive using sonic vibration, Duo-link cement using sonic vibration and abrasion, Theracem self-adhesive, and Duo-link cement. Data were analyzed by one-way analysis of variance, Tukey test, and independent t test (α = 0.05).

Results:
In the coronal region, the bond strength was not significantly different among the four groups (P = 0.331). In the apical region, the bond strength was significantly higher in the Duo-link cement using sonic vibration than in the Theracem cement using sonic vibration (P = 0.010) and Theracem cement using the conventional method (P = 0.007).

Conclusion:
Sonic vibration has positively affects the push-out bond strength of glass fiber post to root dentin using Duo-link cement.

Published: April 2022

Objectives:
Trimethylbenzoyldiphenylphosphine oxide and phenylpropanedione photoinitiator components in resin composites have been used widely due to their white color. However, it seems that there are some limitations in the required polymerization initiator wavelength. This study aimed to evaluate the polywave and monowave light-activating devices (LEDs) on polymerization and shrinkage strain of two dental composites with different photoinitiator systems.

Methods:
In this experimental study, 24 samples were prepared in two groups, including G-Aenial A2 and bleach composites. Each group was divided into two subgroups: one cured by monowave LED unit and the other by polywave device. Then shrinkage strain of samples was evaluated using bonded disk technique.

Results:
Results showed the shrinkage strain of A2 and bleach composites using PW device was significantly greater than MW device. In addition, the A2 composite shrinkage action polymerized with MW device was significantly lower than shrinkage action of A2 and bleach composite using PW machine.

Conclusion:
The findings of this study revealed that polywave LEDs were more beneficial for the polymerization of resin composites.

Published: April 2022

Background and Objectives:
ICMR conducted a multicentric trial “PLACID” that allowed COVID convalescent plasma (CCP) as an experimental drug for the management of moderate COVID-19 disease and the authors' institute was one of the participating centers. The efficacy of CCP in COVID-19 is still debatable. However, unlike therapeutic efficacy, there is not enough literature on issues and challenges faced by health-care institutions in donor recruitment, and the entire vein-to-vein process and approach of CCP transfusion. The authors would like to share their experiences, challenges faced, and their mitigation during the course of donor recruitment, screening, testing, apheresis donation, storage, inventory management, and issue and transfusion of CCP including the regulatory provisions, as their evolution.

Methods:
This retrospective study was conducted over a period of 7 months at a large tertiary care hospital in north India. Based on ICMR guidelines, the study analyzed the screening process and donation from all consecutive potential CCP donors. The study also identified various issues and challenges faced by the institute and how they were resolved.

Results:
Prospective donors registered at the blood center were 843. Majority were males (96.6%), first-time CCP donors (93%), age interval 31–45 years (52.2%), who had a history of mild COVID-19 symptoms (86.9%), and were home-quarantined (83.8%). The most common blood group was B positive (50.6%). Only 6.3% of donors were deferred due to the absence of anti-COVID-19 antibodies. Of 843, 705 selected CCP donors donated 1488 CCP units and six donors (0.8%) experienced mild adverse reactions. Challenges faced by authors included donor recruitment, lack of regulatory approval for plasmapheresis, revisions of COVID-specific selection criteria, no “anti-COVID-19 antibody” kit, and CCP inventory management.

Conclusion:
This study provides real-world comprehensive data on process management of CCP donors and their donations. This understanding of the process, its challenges, and their mitigation could be a template for any possible future pandemic.

Authors: Koju Surendra , Bhatt Rajendra Dev , Shankhadev Ramita , Twitwi Rosna 
Published: April 2022

Background and Objectives:
Blood transfusion is a life-saving procedure and the selection of healthy blood donors is essential steps for safe blood transfusion. Proper selection of blood donors is needed for the safety of both blood donors and recipients. The aim of this study was to assess the demographic profile of blood donors and determine the frequency and reason of donor deferral in a university hospital of Nepal.

Methods:
This hospital-based retrospective study was carried out in the Blood Bank Unit of the tertiary care center of Nepal. Data were collected from the record book maintained in the blood bank from January 2016 to December 2020. Data were analyzed using Microsoft Office Excel 2010 for descriptive analysis.

Results:
A total of 3697 individuals came for blood donation during the study period; among them, 2802 (75.8%) were male and 895 (24.2%) were female. Total number of voluntary donation were 2175 (58.8%), while 1522 (41.2%) were family/replacement donation. Among all donors, 351 (9.5%) donors were deferred for different reasons. The most common cause of donor deferral was hypertension (15.0%), followed by medication (14.0%), while anemia (32.8%) was the leading cause of deferral in female donors. Out of total deferral cases, 92.6% of donors were temporary deferral, while 7.4% were deferred permanently.

Conclusion:
Most deferrals were temporarily due to hypertension, medication, and anemia. Awareness about these causes of deferral can increases the donor pool.

Published: April 2022

Background and Objectives:
Red blood cell (RBC) transfusion continues to be administered on the basis of conventional wisdom and the notion of an average benefit per unit. The present study was aimed at estimating the hemoglobin (Hb) content in packed red blood cell (PRBC) units in three types of blood donors: Replacement blood donor (RD), First time voluntary blood donors (FTVD), and Regular/Repeat voluntary blood donors (RTVD).

Methods:
A total of 900 blood donors were divided equally into three groups of blood donors. Within each group, 100 collections were done in Double 350 ml, Triple 450 ml and quadruple 450 ml blood bags, respectively. The Hb concentration of the PRBC unit was done after the collection of representative samples from the PRBC unit. The volume of the PRBC unit was estimated by the formula: Weight of PRBC divided by its specific gravity. The net Hb content in the PRBC unit was calculated by the formula: Hb of PRBC multiply by its volume.

Results:
Net Hb content of 900 PRBC units were in the range of 30.77–87.36 g; mean was 52.91 ± 9.99 g. Net Hb content of PRBC bag was lower in PRBC prepared from RD as compared to FTVD and RTVD. We observed a range of net Hb content in the PRBC units and Hb content strongly correlated with the volume of PRBC.

Conclusion:
The present study shows that there is a range of Hb content of PRBC units. Adopting a policy of optimizing the dosage of RBC transfusion could have the potential to significantly improve RBC use and decrease patient exposure to allogeneic blood.
Comparison of the effect of propofol and isoflurane on hemodynamic parameters and stress response hormones during Laparoscopic Cholecystectomy surgery
Authors: Ghomeishi Ali , Mohtadi Ahmad Reza , Behaeen Kaveh , Nesioonpour Sholeh , Sheida Golbad Elham , Bakhtiari Nima 
Published: April 2022

Background and Aims:
General anesthesia induces endocrine, immunologic, and metabolic responses.Anesthetic drugs affect endocrine system by changing the level of stress hormones and hemodynamic of the patient . The purpose of this study was to compare the effects of propofol and isoflurane on hemodynamic parameters and stress-induced hormones in laparoscopic cholecystectomy (LC) surgery.

Material and Methods:
Seventy patients of elective LC were included in this study. Patients were randomly divided into two equal groups of 35 patients; group P received propofol (70–120 μg/kg/min) and group I received isoflurane (mac: 1.28%) as anesthesia maintenance. The following parameters were monitored, checked, and recorded from preanesthesia period to 10 min after PACU entry according to a planned method: hemodynamic parameters (heart rate and mean atrial pressure), level of blood sugar, and serum epinephrine level.

Results:
Heart rate and mean atrial pressure changes did not show significant differences between the two groups in all stage (P > 0.05), but isoflurane group tolerated lower fluctuating changes. Blood glucose and serum epinephrine level rise in the isoflurane group were significantly higher than the propofol group (P < 0.05).

Conclusion:
Maintenance anesthesia by inhalation gas base on isoflurane has not shown a significant difference with total intravenous anesthesia base on propofol on hemodynamic parameter. However, propofol has a consistent effect on decreasing stress hormone and suggested for LC surgery.
Risk factors for labor epidural conversion failure requiring general anesthesia for cesarean delivery
Authors: Grap Shannon M. , Patel Gaurav R. , Huang Jessica , Vaida Sonia J. 
Published: April 2022

Background and Aims:
To evaluate the rate and risk factors of labor epidural conversion failure requiring general anesthesia for Caesarean delivery (CD).

Material and Methods:
Pregnant patients requiring conversion from labor to CD with a pre-existing labor epidural at our institution from 2009 to 2014 were identified. Through a retrospective review, we compared successful epidural conversion with those who required general anesthesia for CD. Patient characteristics were analyzed to identify risk factors for failed epidural conversion for CD.

Results:
A total of 673 patients were included in the study. The rate of epidural conversion failure was 21%. Main risk factors for epidural conversion failure requiring general anesthesia included: younger maternal age (95% CI 0.94, P = 0.0002) and supplementation of intravenous fentanyl (95% CI 0.19, P < 0.0001) or midazolam (95% CI 0.26, P = 0.0008) during CD. A higher risk of conversion failure was also associated with a more urgent CD (CD category 1, 2, and 3 vs category 4).

Conclusion:
Consistent with previous reports, young age and the urgency of CD increases the likelihood of epidural conversion failure. While conversion failure is likely multifactorial and complex, many of these factors are suggestive of inadequate and poorly functioning labor epidurals prior to CD. Prospective studies to further evaluate these factors are necessary, and the best prevention of epidural conversion failure is diligent diagnosis and evaluation of ineffective labor epidural analgesia prior to impending CD.
