Les conseillers principaux d’éducation saisis par la « crise ». Enquête sur des agents scolaires dans l’ombre de la « continuité pédagogique »
Authors: Douat Étienne , Michoux Clémence 
Published: December 2021

Prenant principalement appui sur une enquête auprès de Conseillers principaux d’éducation (CPE) réalisée au cours de l’épidémie de coronavirus au printemps 2020, cet article analyse la manière dont cette séquence a reconfiguré les pratiques professionnelles de ces agents scolaires à l’heure de la « continuité pédagogique ». Oubliés dans les discours publics et n’ayant pas reçu de consignes officielles sur le rôle qu’ils devaient jouer lors de la fermeture des établissements, les CPE se sont pourtant retrouvés en première ligne pour faire face aux élèves mis le plus en difficulté par « l’école à la maison ». Le travail relationnel qu’ils ont accompli (l’écoute, le soin et la prise en compte renforcée des conditions matérielles d’existence d’une partie des familles) a produit une confrontation exacerbée avec des situations déstabilisatrices et parfois éprouvantes. Sa montée en puissance a néanmoins permis de renouer avec ce que les CPE considèrent comme leur « cœur de métier », ce dont témoigne une certaine satisfaction professionnelle qu’ils ont pu exprimer pendant la période.

Cette note de synthèse présente les recherches, conduites au cours des trente dernières années, relatives à la place respective des filles/femmes et des garçons/hommes dans les cursus scientifiques. Le corpus intègre 140 publications, en sociologie, sciences de l’éducation, psychologie sociale, histoire et économie. La première partie interroge les enjeux – scientifiques et sociaux – associés à cette thématique. La partie suivante analyse les attitudes des élèves/étudiant.es face aux sciences. La troisième partie présente la façon dont se façonnent ces attitudes différenciées face aux sciences. Elle analyse également les travaux qui considèrent les sciences comme une construction sociale fondamentalement genrée. Enfin, un dernier temps expose des pistes de recherches moins explorées.
Étudier et enseigner les musiques actuelles : les frontières floues d’une expertise en devenir
Authors: Trottier Danick 
Published: December 2021

Suite à un rappel de l’expérience que j’ai acquise à titre de musicologue dans les médias écrits et à la radio, l’article questionne la façon dont l’expertise musicale est perçue puis partagée, autant dans les disciplines ayant pour principal sujet la musique que les disciplines s’y intéressant comme la sociologie et les communications. Le cas des musiques actuelles est au cœur de la réflexion dans la mesure où l’actualité musicale est éloignée de la quête scientifique du musicologue. En outre, le passé musical retient davantage son attention, ce qui s’explique par sa formation universitaire et son travail scientifique. Ce faisant, je rappelle les défis que j’ai dû surmonter lors de la mise sur pied en 2018 d’un cours intitulé Musiques actuelles et scènes pop au Département de musique de l’Université du Québec à Montréal (UQAM). À la lumière de cette expérience et celle acquise dans les médias, il appert que l’expertise en matière de musiques actuelles est davantage le fruit d’une construction et d’un partage au présent entre différentes disciplines et différents groupes d’individus (membres de l’industrie musicale, journalistes, étudiants, fans, etc.) que l’unique chasse gardée des sciences consacrées à la musique, en l’occurrence la musicologie. La réflexion approfondit plusieurs enjeux dans cette perspective et en arrive à la conclusion que le binôme entre experts et non-experts perd de sa consistance dans la connaissance des musiques actuelles.
« Maybe it’s the third world / Maybe it’s the first time around » : variations autour du terme world music chez Paul Simon, de Graceland à Songs from the Capeman
Authors: Fraysse Claire 
Published: December 2021

En 1986, l’album Graceland de Paul Simon provoque un engouement mondial pour les musiques extra-occidentales, en particulier la pop music sud-africaine : ce succès sans précédent et le bourgeonnement parallèle d’autres collaborations musicales multiculturelles permettent la création d’une nouvelle catégorie commerciale, la world music. Mais cette catégorie ne reflète pas un style unifié et ses définitions mouvantes posent de nombreux problèmes de classement musical, de détermination artistique, esthétique, voire sociologique et politique. L’étude des albums Graceland (1986), The Rhythm of the Saints (1990) et Songs from the Capeman (1997) permet toutefois de saisir trois approches différentes de la world music, tout en mettant en lumière le travail de créateur-enquêteur de Paul Simon. Ce dernier joue avec l’ambiguïté définitionnelle de la world music pour proposer différentes productions musicales, chacune centrée sur une problématique intrinsèque à cette catégorie : l’articulation pop locale/pop internationale dans Graceland, le brouillage des pistes entre pop music, folk music, et musique savante dans The Rhythm of the Saints et la déconstruction puis la réactualisation d’influences considérées comme pleinement assimilées à la musique nord-américaine dans Songs from the Capeman.
Efficacy of ultrasound-guided erector spinae plane block following breast surgery – A double–blinded randomised, controlled study
Authors: Thiagarajan Prathiba , Thota Raghu S. , Divatia J.V. 
Published: December 2021

Background and Aims:
Regional anaesthesia has been used to reduce acute post-operative pain as well as opioid-related side effects in breast cancer surgery. Erector spinae plane (ESP) block is a relatively new fascial plane block being tried in various surgical procedures. Our study is a double-blind randomised trial, designed to prove the efficacy of this block in breast surgeries.

Methods:
Seventy female patients scheduled for unilateral breast surgery were enroled in this prospective, randomised, double-blind study. Patients were randomised to group A and group B. All patients received general anaesthesia while group B received additional ultrasound-guided erector spinae block given at thoracic level—T5 with 20ml of 0.25% bupivacaine. Time to first rescue analgesia was the primary outcome. Secondary outcomes were total intraoperative opioid consumption, pain scores over 24 h, post-operative nausea and vomiting and patient satisfaction score at discharge. The Shapiro–Wilk test was used to check the normality of each variable. A comparison was done using Mann–Whitney test and the level of significance was set at 0.05.

Results:
The median time to first rescue analgesia in group A versus group B was 1 h (1–12h) versus 8 h (1–26h), respectively, with a P value of 0.044. Group B patients had lower pain scores post-operatively and better satisfaction scores at discharge. There was no statistically significant difference in intraoperative fentanyl consumption.

Conclusion:
Ultrasound-guided ESP block with general anaesthesia offers superior post-operative analgesia compared to general anaesthesia alone in patients undergoing unilateral nonreconstructive breast cancer surgeries.
Multi-Modality Medical Image Fusion Using Cross-Bilateral Filter and Neuro-Fuzzy Approach
Authors: Kaur Harmeet , Kumar Satish , Behgal Kuljinder Singh , Sharma Yagiyadeep 
Published: December 2021

Context:
The proposed technique uses the edge-preserving capabilities of cross-bilateral filter (CBF) and artificial intelligence technique adaptive neuro-fuzzy inference system (ANFIS) to fuse multi-modality medical images.

Aims:
The aim is to present the unlike information onto a single image as each modality of medical image contains the unalike domain of information.

Settings and Design:
First, the multi-modality medical images are decomposed using CBF by tuning its parameters: radiometric and geometric sigma producing CBF component and detail component. This detail is fed to ANFIS for fusion. On the other hand, the sub-bands obtained from DWT are fused using average rule. Reconstruction method gives final image.

Subjects and Methods:
ANFIS is used to train the Sugeno systems using neuro-adaptive learning. The fuzzy inference system in the ANFIS is used to define fuzzy rules for fusion. On the other hand, bior2.2 is used to decompose the source images.

Statistical Analysis Used:
The performance is verified on the Harvard database with five cases, and the results are equated with conventional metrics, objective metrics as well as visual inspection. The statistics of the metrics values is visualized in the form of column chart.

Results:
In Case 1, better results are obtained for all conventional metrics except for average gradient (AG) and spatial frequency (SF). It also achieved preferred objective metric values. In Case 2, all metrics except AG, mutual information, fusion symmetry, and SF are better values among all methods. In Cases 3, 4, and 5, all the metrics have achieved desired values.

Conclusions:
Experiments conclude that conventional, objective, visual evaluation shows best results for Cases 1, 3, 4, and 5.
A cross-sectional study of pre- and posttraining evaluation of inhaler use technique among outpatients with bronchial asthma or chronic obstructive pulmonary disease at a tertiary care hospital in India
Authors: Nitya Selvaraj , Kiruthika Sivagourounadin , Meenakshi R. , Suriya H. , Yuvarajan S. 
Published: December 2021

Context:
Management of asthma and chronic obstructive pulmonary disease (COPD) includes use of inhalers as an integral component of drug delivery. Awareness about inhaler devices along with demonstration of the usage of inhaler technique aids in the optimization of therapeutic outcome.

Aim:
This study aimed to assess the correct use of inhaler technique following pre- and posttraining sessions for the management of COPD and asthma among pulmonary outpatients at a tertiary care hospital.

Settings:
This prospective cross-sectional study was carried out among patients diagnosed with asthma or COPD and prescribed with inhaler medication in the form of pressurized metered-dose inhaler (pMDI), MDI with spacer, or dry powder inhaler (DPI).

Subjects and Methods:
The inhaler device use by the patients was assessed initially, followed by a demonstration on inhaler device technique, and reassessed post training using a checklist.

Statistical Analysis:
Comparison of the median total score of pretraining and posttraining inhaler technique was analyzed by Wilcoxon signed rank test. P < 0.05 was considered statistically significant.

Results:
Out of 144 patients, 55.6%, 27.7%, and 16.7% of them were prescribed pMDI, MDI with spacer, and DPI, respectively. Post inhaler technique training, about 79.2% of the patients were able to demonstrate the inhaler technique correctly compared to 52.1% prior to training. A statistically significant difference in the median score of inhaler technique has been observed before and after training.

Conclusions:
This study reports a significant improvement in the correct use of inhaler technique post training. In addition, the most frequent error among inhaler users was revealed to be in the breath actuation.
Biphasic Change in Renal Function after Radical Cystectomy and Urinary Diversion
Authors: Attawettayanon Worapat , Anukoolphaiboon Apiwich , Chalieopanyarwong Virote , Pripatnanont Choosak 
Published: December 2021

Purpose:
Radical cystectomy (RC) with urinary diversion has been established as the gold standard treatment for muscle invasive bladder cancer. This provides excellent local control and increases the survival rate. The postoperative renal function (RF) usually declines, especially with those with risky conditions such as increasing age, hypertension, diabetes, or the presence of preoperative hydronephrosis (HN). However, there are limited data about the potential preoperative factors to predict the postoperative RF following the RC. The current retrospective article aims at reviewing patients treated with RC with urinary diversion presenting demographics data, assessing the RF after performing the operation and identifying the associated factors that reduce the RF.

Materials and Methods:
Bladder cancer patients who underwent RC with a urinary diversion from January 2001 to December 2017 were reviewed. RF was assessed by using the estimated glomerular filtration rate (eGFR) through the MDRD formula. Multivariate analysis was performed to evaluate the association of the changing of RF.

Results:
One hundred and fifty-six patients were included in the study. The median age was 65 years (interquartile ranges [IQR] 57, 72), and the median follow-up time was 16.4 months (IQR 7.1, 33.4). Overall, 86 patients (55.12%) had HN at the initial treatment of RC. Baseline mean eGFR was 57.7 mL/min/1.73 m2 (standard deviation [SD] = 23.7). The value of eGFR observed at 1, 12, and 60 months was 67.2 (SD = 29.5), 55.7 (SD = 26.3), and 55.8 (SD = 21.4) mL/min/1.73 m2, respectively. At 1 month, female gender, no HN, and neobladder were independently associated with worse RF outcomes in both univariate and multivariate analysis (P < 0.05). The factors associated with eGFR under 60 mL/min/1.73 m2 at 1 year were age, presence of HN, and adjuvant treatment.

Conclusion:
RF after cystectomy and urinary diversion improves for 1 month after the procedure, especially in patients with the presence of preoperative HN and then RF gradually decreases. There are no significant differences in preoperative and postoperative RF after a 5-year follow-up.

Authors: Chang Li-Wen , Hung Sheng-Chun , Li Jian-Ri , Chen Chuan-Shu , Yang Cheng-Kuang , Cheng Chen-Li , Ou Yen-Chuan , Ho Hao-Chung , Chiu Kun-Yuan , Chang Chao-Hsiang , Wang Shian-Shiang 
Published: December 2021

Objectives:
To evaluate the efficacy of instillations with mitomycin C (MMC) or bacillus Calmette–Guérin (BCG) in patients with T1 high-grade bladder cancer (BC).

Patients and Methods:
From 2007 to 2015, 186 patients admitted to Taichung Veteran General Hospital with new diagnosis of T1 high-grade BC receive transurethral resection of the bladder tumor (TURBT) and 6 weekly adjuvant instillation following. Histological stage followed the WHO grading system. End point evaluation was recurrence and progression to muscle invasive BC.

Results:
A total of 118 patients received 6 weekly intravesical instillation chemotherapy with MMC and 68 with BCG. Above all, 93 patients received immediate intravesical MMC after TURBT. The mean follow-up period was 46.78 ± 19.05 months in the MMC group versus 50.13 ± 24.18 months in the BCG group (P = 0.512). The BCG group showed better outcomes with longer 5-year recurrence-free survivals (64.6% vs. 50.0%, P of log rank = 0.008*) and progression-free survivals (94.1% vs. 87.3%, P of log rank = 0.023*). The treatment efficacy of BCG in comparison to MMC was further adjusted in uni-multivariate analysis model (recurrence: Hazard ratio [HR] =0.511, 95% confidence interval [CI] = 0.304–0.858, P= 0.011*; progression: HR = 0.216, 95% CI = 0.068–0.683, P= 0.009*). We also explore smoker, multiple lesions, and tumor diameter >3 cm to be risk factors for recurrence.

Conclusions:
For patients with T1 high-grade nonmuscle invasive BC, the adjuvant therapy with BCG, as opposed to MMC, resulted in better outcomes based on recurrence and progression with tolerable complications. For immediate single instillations, in comparison, the efficacy was lower in preventing tumor recurrence and progression in the current stage.

Authors: Hany Normeen , Bahgat Amal , Youssef Omnya , Fayyad Amr , Kotb Amira , Al-Khatib Sara , Fathy Mona 
Published: December 2021

Purpose:
This study is aimed to assess the serum expression levels of miR-210 and microRNA-23b (miR-23b) in bladder cancer (BC) patients to evaluate their potential as noninvasive biomarkers.

Materials and Methods:
This study included 93 subjects divided into the following three groups: Group Ia, 31 patients newly diagnosed with BC; Group Ib, Group Ia patients 6 months after medical and/or surgical treatment; and Group II, 31 healthy controls. The gene expressions of miR-210 and miR-23b were determined using quantitative SYBR Green reverse transcription real-time polymerase chain reaction.

Results:
The expression of miR-210 was significantly higher in BC patients compared to the controls (P = 0.012), while miR-23b did not show any difference. miR-210 expression in BC patients did not differ before and after treatment (P = 0.89). Area under the curve of the receiver operating characteristic analysis for miR-210 in distinguishing BC from controls was 0.686 (95% confidence interval, 0.553–0.818) with 71% sensitivity and 61% specificity.

Conclusion:
miR-210 can serve as a noninvasive diagnostic marker for BC; however, it cannot be used during treatment follow-up. miR-23b cannot be used as a diagnostic nor prognostic marker for BC.

Authors: Huang Ching-Wei , Wang Ta-Min , Weng Li-Chueh , Chen Hsiao-Wen 
Published: December 2021

Introduction:
The study aimed to find a secure procedure for circumcision, using monopolar diathermy with several key steps of technique to facilitate the surgical process and minimize the postoperative complications.

Methods:
Patients who underwent the secure technique for circumcision, due to different reasons, from 2012 to 2016 were retrospectively reviewed. A monopolar coagulator with a needle point probe with energy ranging from 10 to 15 W was used to perform the circumcision by following several key steps. In addition, tissue glue was applied to the wound to provide operative wound care. All data referring to patient demographics were recorded. The outcomes and complications associated with the secure technique for circumcision were assessed.

Discussion:
One hundred and ten children underwent this technique, carried out by a senior teaching staff member and several senior residents. All patients were followed with a mean of 29.5 ± 30.1 days postoperatively. All these patients were satisfied with the operation and had no major complications, and no second revisions were needed during the follow-up period. Two patients (1.8%) had a minor wound infection, which was resolved with oral antibiotics within 1 week. However, the study limitations included its retrospective nature and the heterogeneity of the study population.

Conclusion:
Modified diathermy circumcision with the secure technique protects the penile phallus and urethra, and it is associated with a low rate of complications, as hemostasis can be simultaneously ensured. The technique is feasible, simple, and easy to learn. In addition, tissue glue was proved to facilitate postoperative wound care.
The Simple Solution for Infertile Patients with Aspermia in the Modern Era of Assisted Reproductive Technique
Authors: Fan Le-Wei , Shao I-Hung , Hsieh Ming-Li 
Published: December 2021

Purpose:
The purpose is to investigate the feasibility and outcomes of loupe-assisted vasostomy for sperm retrieval in male infertility due to anejaculation or retrograde ejaculation.

Materials and Methods:
We retrospectively reviewed the vasal sperm aspirations of 9 patients with anejaculation or retrograde ejaculation from 2015 to 2017. We collected preoperative serum hormone data (testosterone, follicle-stimulating hormone, luteinizing hormone, and prolactin) and comorbidities of each patient. The patients underwent standard loupe-assisted modified vasostomy by a single surgeon with immediate specimen interpretation, with follow-up at the clinic.

Results:
Of the 9 patients, 4 had retrograde ejaculation, and 5 had anejaculation. Seven patients had controlled diabetes mellitus; of them, one had an ejaculating duct stone, and only one had no comorbidity. Aspirations were performed for sequential assisted reproductive techniques in 7 patients and cryopreservation in another two. The average total sperm count was 213 × 106, with motility between 9% and 67% and normal sperm morphology between 4.5% and 50.0%. One patient had undergone microsurgical epididymal sperm aspiration before vasal aspiration, but the semen analysis indicated poor sperm quality and could not be used for in vitro fertilization. In total, 7 of the 8 aspirations (87.5%) resulted in pregnancy. No complications have been observed to date.

Conclusion:
Vasal sperm aspiration is a simple and effective alternative method for sperm retrieval, with the advantage of a high success rate and less invasiveness and destruction of the reproductive system. It may be performed before sperm retrieval from the epididymis or testis in infertile men with aspermia.
Comparison of the Effects of Tamsulosin, Silodosin, and Alfuzosin on Catheter-Free Trials after Acute Urinary Retention Due to Benign Prostatic Hyperplasia
Authors: Parikh Aditya , Yagnik Vipul D , Contractor Rajivkumar , Vyas Jigish , Dawka Sushil 
Published: December 2021

Purpose:
We compared tamsulosin, silodosin, and alfuzosin in catheter-free trials after acute urinary retention (AUR) due to benign prostatic hyperplasia (BPH). This study aims at assessing the efficacy of tamsulosin, silodosin, and alfuzosin, and the factors affecting the success of catheter-free trials.

Materials and Methods:
An observational, prospective, randomized study of 49 men with AUR due to BPH was performed from July 2015 to August 2017. Participants were catheterized after the assessment of prevoid urine volume. The prostate size was measured, and IPSS at presentation was calculated. The participants were divided into tamsulosin, silodosin, and alfuzosin groups and were given a catheter-free trial after administration of alpha-blockers for three doses. Descriptive analysis, independent t-test, and Chi-square test were used for data analysis. Univariate and multivariate analyses were done using STATA software version 14.2. P < 0.05 was considered to indicate statistical significance.

Results:
The overall success of trial without catheter (TWOC) was 62.5% (30 out of 49). There was no difference in the efficacy of tamsulosin, silodosin, and alfuzosin in catheter-free trials after AUR due to BPH. The success of TWOC was affected by median lobe enlargement, and patients with Grade 3 intravesical protrusion of prostate were less likely to have a successful TWOC.

Conclusion:
TWOC after administration of three doses of alpha-blockers was shown to be useful in most patients irrespective of prostate size. There was no difference in the efficacy of tamsulosin, silodosin, and alfuzosin in catheter-free trials.
