4. La critique du productivisme est-elle réductible à une critique du capitalisme ? Une analyse des régimes de fonctionnement du concept de production chez Marx
Authors: Sobel Richard 
Published: June 2021

Cet article étudie le rapport qui pourrait sembler paradoxal entre productivisme et écologie dans la pensée de Marx. Pour ce faire, nous proposons d’analyser le productivisme chez Marx comme un dispositif conceptuel combinant un aspect explicatif et un aspect normatif, dispositif dont on ne peut comprendre pleinement le sens et la portée qu’en le référant à son arrière-plan ontologique, l’être comme production. Si ce dispositif est particulièrement efficace pour comprendre les tenants et aboutissants de la pathologie productiviste qui est au cœur du mode de production capitaliste, il semble faire croire que cette critique épuise toute critique du productivisme, laissant comme point aveugle la question du productivisme dans l’horizon de l’utopie communiste.

5. La place controversée de l’évaluation monétaire au sein du courant d’économie écologique : retour sur une histoire tumultueuse
Authors: Méral Philippe 
Published: June 2021

L’histoire de la pensée économique dans le domaine de l’environnement est marquée par la naissance à la fin des années 1980 du courant d’économie écologique. Initialement, ce courant se voulait en opposition à l’économie de l’environnement et des ressources naturelles issues de l’analyse néo-classique. Toutefois, au fil du temps, les lignes de fracture entre ces deux courants sont devenues de plus en plus floues ; créant des passerelles entre les auteurs, les concepts, les méthodologies et les outils. L’objectif de cet article est d’analyser cette évolution en prenant appui sur une des controverses : l’évaluation monétaire de l’environnement. Cette controverse se manifeste plus particulièrement suite à la parution de l’article « The value of the world’s ecosystem services and natural capital » , publié dans la revue Nature en 1997 et porté par un des fondateurs du courant d’économie écologique, Robert Costanza.

Changes in Central Corneal Thickness With Air-Puff–Induced Corneal Deformation Using a Method to Correct Scheimpflug and Refractive Distortion
Authors: Okon Monica D. , Ma Yanhui , Liu Jun , Roberts Cynthia J. 
Published: June 2021

PURPOSE:
To establish a method to determine central corneal thickness (CCT) and anterior chamber depth (ACD) of an air-puff–deformed cornea at the highest concavity (HC) state.

METHODS:
The Fink method for refractive correction of Scheimpflug images of a convex pre-deformed (PRE) cornea was implemented for 155 eyes of 155 participants imaged with the Corvis ST (Oculus Optikgeräte GmbH). This method was subsequently modified for the HC state of deformation. The tracked edges of each participant's cornea were exported at the PRE and HC states. Ten participants who had a visible crystalline lens in the image were selected to determine ACD in both states. The center points on the corneal tracked edges and lens were used to determine uncorrected CCT and ACD, respectively.

RESULTS:

Average undeformed CCTPRE was significantly lower than deformed CCT
HC
(584 ± 31 and 626 ± 34 µm, respectively) (
P
< .0001). No significant difference was found for the corrected ACD between the two states. Corrected CCT and ACD were significantly greater than the corresponding uncorrected values for both deformation states (
P
< .0001). Percent change in CCT was found to be correlated to change in arc length at HC (
P
< .0001).

CONCLUSIONS:
Distortion in Corvis ST images at the HC state can be corrected using a modified Fink method. CCT was found to increase in the HC state, compared to the PRE state. The CCT change during deformation may be important in the study of the compressive response of the cornea.

Authors: Schallhorn Steven C. , Schallhorn Craig S. , Teenan David , Venter Jan A. , Hannan Stephen J. , Schallhorn Julie M. 
Published: June 2021

PURPOSE:To evaluate clinical outcomes 1 year after implantation of an extended depth of focus intraocular lens (IOL) in a large series of patients.METHODS:Outcomes of patients who underwent refractive lens exchange or cataract surgery with the implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec AG) were retrospectively reviewed. The near (40 cm), intermediate (66 cm), and distance visual acuity, refractive outcomes, and cumulative rate of adverse events and secondary procedures were evaluated at 12 months postoperatively.RESULTS:A total of 1,894 eyes of 977 patients were implanted with the AT LARA 829MP IOL, with 62.1% of eyes available for the 12-month visit. The overall secondary procedure rate for the whole cohort was: Nd:YAG = 7.8%, laser vision correction = 7.5%, and IOL explantation = 0.63%. The reasons for IOL exchange were intraoperative complications (3 eyes/0.16%) and quality of vision issues (9 eyes/0.48%). Of all eyes available for the 12-month visit that did not undergo laser vision correction or an IOL exchange, 72.0% had monocular uncorrected distance visual acuity of 20/20 or better and the percentage of eyes with monocular uncorrected intermediate and near visual acuity of 20/50 or better was 96.2% and 81.0%, respectively. At 12 months postoperatively, 87.6% of eyes were within ±0.50 diopters of emmetropia. No change in refraction occurred between the 6- and 12-month postoperative visits.CONCLUSIONS:The AT LARA 829MP extended depth of focus IOL is able to provide functional distance, intermediate, and near visual acuity. Complications related to the platform of the IOL were uncommon.[J Refract Surg. 2021;37(6):380–388.]
Use of Adjustable Intraocular Lens After Cataract Surgery in a Patient With Post-LASIK Ectasia Stabilized With CXL
Authors: Hura Arjan S. , Jee Kathleen J. , Wiley William F. 
Published: June 2021

PURPOSE:
To describe a case of a patient who developed corneal ectasia after laser in situ keratomileusis and first underwent corneal cross-linking, followed by sequential cataract surgery with implantation of the Light Adjustable Lens (RxSight).

METHODS:
Case report.

RESULTS:
The patient had a good postoperative outcome with an uncorrected visual acuity of 20/20 at distance and 20/30 at near. The patient reported overall satisfaction with the outcome.

CONCLUSIONS:
Despite careful planning and proper lens selection, refractive surprises are not uncommon when performing cataract surgery in eyes that have had refractive surgery or eyes with corneal ectasia after refractive surgery. In these cases, the Light Adjustable Lens may be a good option to achieve the desired postoperative refractive outcome.

Corneal Cross-linking for Keratoglobus Using Individualized Fluence
Authors: Hafezi Farhad , Torres-Netto Emilio A. , Randleman J. Bradley , Hafezi Nikki L. , Mazzotta Cosimo , Ambrósio Renato , Kollros Léonard 
Published: June 2021

PURPOSE:
To present a case of bilateral progressive keratoglobus that was successfully arrested with corneal cross-linking (CXL) applying the sub400 individualized fluence protocol.

METHODS:
Case report.

RESULTS:
A 36-year-old man with bilateral progressive keratoglobus and no history of eye rubbing presented with a corrected distance visual acuity (CDVA) of 20/200 in the left eye. Progression in the left eye was confirmed using previously taken corneal topographies and comparing them to high-resolution Scheimpflug imaging, high-speed dynamic Scheimpflug imaging, and anterior segment optical coherence tomography. Epithelium-off CXL was performed in the left eye using individualized fluence that was adapted to the thickness of the corneal stroma immediately prior to irradiation (sub400 protocol). Postoperative follow-up of 32 months showed stabilization of keratometric values and no endothelial cell loss.

CONCLUSIONS:
The sub400 epithelium-off CXL protocol using individualized fluence may arrest progressive keratoglobus and might represent a novel therapeutic approach for the management of keratoglobus.

Les représentations en psychologie du travail, de la formation, et en didactique des disciplines scientifiques
Authors: Rogalski Janine 
Published: June 2021

Cet article propose un tour d’horizon du terme et de la notion de « représentation » dans le cadre de la psychologie cognitive ; on en rappelle la polysémie et le caractère multidimensionnel. Ce cadre posé, on aborde deux problématiques actives en psychologie ergonomique et didactique professionnelle, et en didactique des disciplines scientifiques. On discute d’abord des relations entre représentations « internes », « états mentaux » d’un sujet, et représentations « externes », exprimées dans une diversité possible de registres sémiotiques. Les représentations internes sont des « constructs » inférés par l’analyste à partir des conduites du sujet (incluant les représentations externes qu’il produit, dont les verbalisations). Les représentations externes sont une forme de réalisation (donc matérialisée) de ce qui est représenté, manipulable dans le(s) registre (s) utilisé(s) : elles ont de ce fait des caractères producteurs mais aussi des caractères réducteurs, dont on discutera des effets didactiques. On présente ensuite une organisation de systèmes de représentations mettant en relation des représentations, épistémiques ou pragmatiques, socio-historiquement produites par des communautés de référence (de pratiques professionnelles ou d’enseignement) et les représentations du sujet, opérateur ou élève, et les représentations du point de vue de l’analyste. On conclut par deux questions vives : l’utilisation des représentations externes comme outils pour la formation, et le statut des représentations dans les activités collectives.

Authors: Saillot Éric 
Published: June 2021

Cet article présente la caractérisation pragmatique de l’enrôlement des élèves en difficulté qui est issue d’une recherche descriptive et compréhensive de l’activité d’enseignement de cinq professeurs des écoles en situation d’aide personnalisée (Saillot, 2011), dispositif de soutien pédagogique institutionnalisé en France de 2008 à 2013. Menée dans la perspective de la didactique professionnelle (Pastré, Mayen, Vergnaud, 2006 ; Vinatier, 2009) de l’analyse de l’activité d’enseignement basée sur l’analyse pragmatique des discours-en-interaction (Kerbrat-Orecchioni, 2005), et spécifiquement sur le traitement des actes de langage (Austin, 1970 ; Kerbrat-Orecchioni, 2008) des professeurs des écoles lorsqu’ils communiquent à l’oral avec leurs élèves au cours des séances d’aide personnalisée, cette étude nous a permis de décrire du point de vue langagier les trois principales phases ainsi que les cinq principaux déterminants de l’enrôlement des élèves en difficulté.

Published: June 2021

Background:
Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients.

Main recommendations:
1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control.

Changes in management:
The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
A nomogram for predicting acute respiratory distress syndrome in COVID-19 patients
Authors: Ding Ning , Zhou Yang , Yang Guifang , Chai Xiangping 
Published: June 2021

Objective:
To predict the in-hospital incidence of acute respiratory distress syndrome (ARDS) in COVID-19 patients by developing a predictive nomogram.

Methods:
Patients with COVID-19 admitted to Changsha Public Health Centre between 30 January 2020, and 22 February 2020 were enrolled in this study. Clinical characteristics and laboratory variables were analyzed and compared between patients with or without ARDS. Clinical characteristics and laboratory variables that were risk factors of ARDS were screened by the least absolute shrinkage and selection operator binary logistic regression. Based on risk factors, a prediction model was established by logistic regression and the final nomogram prognostic model was performed. The calibration curve was applied to evaluate the consistency between the nomogram and the ideal observation.

Results:
A total of 113 patients, including 99 non-ARDS patients and 14 ARDS patients were included in this study. Eight variables including hypertension, chronic obstructive pulmonary disease, cough, lactate dehydrogenase, creatine kinase, white blood count, body temperature, and heart rate were included in the model. The area under receiver operating characteristic curve, specificity, sensitivity, and accuracy of the full model were 0.969, 1.000, 0.857, and 0.875, respectively. The calibration curve also showed good agreement between the predicted and observed values in the model.

Conclusions:
The nomogram can be used to predict the in-hospital incidence of ARDS in COVID-19 patients.
Dental Students' Perception Towards Feedback during Clinical Training
Authors: Nerali Jayashri Tamanna , Chakravarthy Pishipati Vinayak Kalyan , Telang Lahari Ajay , Telang Ajay 
Published: June 2021

Background and Aim:
Feedback is an essential element in the clinical training of dental students which paves way for the achievement of learning outcomes and also to improve their future performance. The aim of this study was to analyze dental students' perceptions of importance, process, and content of feedback received during their clinical training.

Materials and Methods:
A cross-sectional, questionnaire was developed and validated and distributed to dental students (n = 178) of years 3, 4, and 5. Descriptive analysis and one-way ANOVA were used to compare the mean scores between the three groups. Open-ended responses were analyzed qualitatively.

Results:
The majority of students agreed that feedback on clinical performance is needed to improve learning and identify areas for improvements. Most of the students prefer one-to-one feedback, in a timely and regular manner and immediately after the clinical session. Eighty-six percent believed that feedback should be given with mutual respect. Most of the students disagree (80%) that marks/grades are an important part of the feedback. Students preferred feedback with positive and negative comments about their clinical work (93%), which would help them to engage in the process of learning and to make an action plan for future learning process.

Conclusions:
Students are aware of the purpose and importance of feedback and preferred timely, structured, and constructive feedback on their clinical performance. The dental clinical environment is stimulating and dynamic and the role of faculty feedback is crucial for students to reflect on their learning and improve future performance.
Can Hospital Doctors Provide Quality Palliative Care Informed by End-of-Life Care Legislation
Authors: Wong Aaron K. , Carey Susan E. , Kenner David J. 
Published: June 2021

Background and Aim:
Approximately 50% of deaths in Australia occur in hospitals, and this number is growing. Studies consistently show that doctors have poor knowledge of end-of-life decision making; however, this has not been examined in specific groups of hospital doctors. We examined hospital doctors' knowledge of key elements of end-of-life care legislation.

Materials and Methods:
We conducted a prospective, observational, cross-sectional study of doctors from a large Australian public tertiary health network using six questions formulated on basic key elements of the legislation. Demographic data collected included years of work experience, clinical unit, and proportion of work hours spent with dying patients.

Results:
Of the 201 doctors censored, senior doctors (>10 years' experience) were the least knowledgeable group. Only approximately 20% of doctors correctly answered all questions. Thirty-two percent would potentially provide futile treatment if demanded by a competent patient. Fifty percent did not know how to locate an advance directive in the hospital record. There was confusion regarding the role of the substitute decision-maker.

Conclusions:
Approximately a quarter of hospital doctors practise with a poor understanding of the law over the various domains. The urgent call for education is further highlighted not only for students and junior doctors but also for senior doctors who scored poorly. Educational efforts could begin from addressing the simple key areas of legislation covered in the survey.
Prevalence of Psychological Morbidities and their Influential Variables among Nurses in a Designated COVID-19 Tertiary Care Hospital in India
Authors: Garg Sunny , Yadav Megha , Chauhan Alka , Verma Dinesh , Bansal Kirti 
Published: June 2021

Background and Aim:
Nurses are the main part of the health work force, performing their duties as frontline warriors against the novel coronavirus pandemic. Nurses involved in the care of infected (COVID-19) patients, may feel more discomfort physically, and experience greater psychological morbidities. The main aim of the study is to evaluate the prevalence of anxiety and stress among nurses in a designated COVID-19 hospital and variables that influence these psychological problems.

Materials and Methods:
Nurses working in the designated tertiary care hospital were invited to participate in an online cross-sectional survey (dated, 5–15 September 2020). A total sample size of 236 was calculated. A self-administered questionnaire regarding sociodemographic characteristics, COVID-19-related experiences, perceived threat regarding COVID-19 and two scales (Generalised Anxiety Disorder-7 and Perceived Stress Scale-10) for assessment of anxiety, and stress was applied to nurses. Chi-square test and multiple regression analysis were used to investigate the predictors (risk and protective) of psychological morbidities in nurses.

Results:
On analysis of 209 participants, it was revealed that 65 (31.1%) participants have anxiety symptoms and 35.40% have moderate-to-high level of stress. Being proud of working in this profession was the only protective factor from such psychological morbidities. The identified risk factors for greater anxiety symptoms and moderate-to-high level stress were working experience of more than 10 years (odds ratio [OR] = 3.36), direct involvement in care of suspected/diagnosed patients (OR = 3.4), feeling worried about being quarantined/isolated (OR = 1.69), and high risk of being infected at job (OR = 2.3 for anxiety and OR = 2.1 for moderate-to-high stress).

Conclusions:
Deteriorating psychic health of nurses is one of the major outcomes during COVID-19 pandemic in India which warrants the necessity of providing psychological support to all the nurses particularly those who are frontline workers and have working experience of more than 10 years and controlling the risk factors related to these problems.
A Study on Depression, Anxiety, Stress, and Life Quality among Medical Aspirants and Medical Students of Aligarh City in North India
Authors: Khursheed Manal , Naseem Sufia 
Published: June 2021

Background and Aim:
Rapid intellectual and psychosocial development occurs mainly during young adulthood. Coincidently, decisions regarding collegiate and professions are taken during this period. Thus, adulthood is vulnerable to psychological disorders. Contrary to most other professions, medical education is more likely to affect mental health. The present explicates the prevalence of depression, anxiety, and stress among premedical and medical students of Aligarh city, and various coping mechanisms they adopt to mitigate above symptoms. Assessment on students' quality of life (QOL) has also been made.

Materials and Methods:
The study sample (220) consisted of 11th and 12th pursuing and 12th passed students preparing for medical entrance examinations and those pursuing the medical course. The study protocol was approved by the Institutional Ethics Committee. The method of online survey was questionnaire through Google forms. Study lasted for 3 months. We used Depression Anxiety Stress Scale and World Health Organization QOL (WHOQOL)-BREF (QOL assessment scale developed by WHO) questionnaires.

Results:
Our study suggests that levels of extremely severe anxiety (37.7%) and depression (20%) were relatively higher than stress (10.9%) in the respondents. The Pearson's Chi-square alpha and the P value indicated that depression, stress and anxiety were quite gender centric. We also found significantly higher levels of depression, stress, and anxiety in 11th, 12th pursuing, 12th passed students preparing for medical entrance, final professional (Part 2) students, and interns. Furthermore, physical domain of QOL score showed strong negative correlation with depression, stress, and anxiety.

Conclusion:
The present study found that depression, stress, and anxiety are present among medical as well as premedical students. It is a matter of concern, as the conditions may severely affect the health as well as the performance of students.
