Quel type de citoyenneté en Anthropocène ?
Authors: Wallenhorst Nathanaël
Published: November 2023

Cette contribution prend acte de l’altération de nature anthropique du système Terre et pose la question du type de citoyenneté en référence auquel penser l’éducation au politique en Anthropocène. Après avoir discuté la thèse de Daniel Curnier autour de l’apprentissage d’une citoyenneté critique à l’égard du néolibéralisme de l’école, nous explorons la figure du citoyen existentiel de Christian Arnsperger. Ces deux premières sections permettent ensuite d’interroger les travaux du philosophe et biologiste allemand Andreas Weber avec sa thèse de l’être appréhendée comme un partage entre humains et non-humains, à partir de laquelle nous proposons l’idée de citoyenneté conviviale caractérisée par une coexistence avec ces autres terriens, les non-humains.
Transition et éducation écologiques en odyssée
Authors: Prouteau François
Published: November 2023

Nous vivons un changement de monde, déstabilisant pour beaucoup. Ceux qui se croyaient maîtres et possesseurs de la nature déchantent au regard des catastrophes qui nous arrivent. Au plus près du terrain, des individus, les jeunes générations en particulier, les « Télémaque » d’aujourd’hui, se mobilisent. Serait-ce une invitation à lire avec des yeux neufs l’épopée homérique ? À penser la transition écologique et l’éducation comme une odyssée ?
Éduquer, c’est déjà lutter
Authors: Hétier Renaud
Published: November 2023

L’Anthropocène se profile comme un temps d’effondrements. Or, il nous semble qu’il est déjà la résultante d’effondrements précédents, qui sont d’ordre spirituel et psychique, qu’il s’agit d’analyser, pour penser une éducation qui redonne les forces nécessaires. Les enfants et les adolescents sont aujourd’hui dans une position particulière : surprotégés, surinformés, ils sont en même temps « exclus » de la vie politique, qui, notamment en matière d’écologie, les concerne au premier chef. Il s’agit alors de voir comment les aider à sentir, penser et participer. À notre sens, l’éducation est déjà une lutte, dans la mesure où elle doit aller contre la virtualisation et l’abstraction de nos vies, et refonder un pouvoir de sentir. Seront résistants les individus qui seront suffisamment « enracinés ». Cet enracinement n’est pas seulement un enracinement dans la nature, il est aussi un enracinement dans la vie. Il importe que les enfants et les adolescents sentent le « plaisir d’être », de façon à éprouver le « désir d’être », et à vouloir aussi que le monde soit.
La relation d’aide
Authors: de Mijolla-Mellor Sophie
Published: November 2023

Partant de l’idée que toute relation d’aide est rendue possible par le fait que l’aidant trouve en l’aidé un prolongement de son propre narcissisme, ce texte étudie à partir de la notion de détresse (désaide ou Hilflosichkeit ) ce qui advient lorsque l’aidant est un parent vis-à-vis d’un enfant, un enfant vis-à-vis d’un parent âgé ou quand, dans un couple, l’un des deux entre dans une maladie incurable.
Clinique du COVID. Transfert et écriture à l’épreuve de la crise
Authors: Desjardins Ludovic
Published: November 2023

La crise sanitaire est venue bousculer nos quotidiens, nos pratiques et nos institutions d’une manière à la fois soudaine et durable. Au cœur de la crise, une clinique se dessine. Elle parle d’une colère, d’une coupure des liens et d’une impuissance. Entendre ces mouvements est un enjeu important pour la clinique. Cet article retrace une expérience au sein d’une unité « Covid ». Au sein de ce service si particulier, l’impossible a finalement pu laisser place à quelques surprises.
L’ambiguïté du Rot un Wiss
Authors: Vaillot Benoît
Published: November 2023

À l’issue de la guerre de 1870, la France défaite se voit contrainte de céder des territoires à l’Empire allemand qui formeront jusqu’en 1918 la Terre d’Empire d’Alsace-Lorraine ( Reichsland Elsaß - Lothringe n ). Au cours de cette période où la souveraineté allemande est contestée, les habitants emploient de façon croissante un drapeau rouge et blanc à bandes horizontales appelé tardivement  Rot un Wiss (« rouge et blanc » en dialecte), dont les autorités ne réussissent pas tout à fait à comprendre le sens politique. Les avancées institutionnelles accordées à l’Alsace-Lorraine au début du 20 e  siècle permettent d’engager une discussion institutionnelle quant à l’adopter officiellement, mais sans jamais aboutir. L’étude des débats relatifs à l’attribution d’un pavillon pour ce territoire et l’analyse de ses usages, ses perceptions et son appropriation par les populations permettent de comprendre la place ambiguë que peut occuper un drapeau dans la construction des identités collectives.
Au drapeau !
Authors: Lapille Jean-Félix
Published: November 2023

Éléments essentiels du répertoire symbolique, les drapeaux des partis fascistes de France et de Belgique n’ont pas fait l’objet d’une étude spécifique. Ceux-ci permettent pourtant d’appréhender les stratégies et les cultures politiques d’un parti. Leur étude se fonde plus particulièrement sur l’exemple du francisme, du rexisme, du PPF qui traversent les années 1930 dans l’orbite des fascismes. Avec la défaite et l’occupation, ces trois partis, auxquels s’ajoute le RNP, font le choix de la collaboration avec le Reich , ce qui entraîne la modification ou la réinterprétation des symboles passés dans lesquels se fondait et se reconnaissait un groupe.
Des moments vexillaires de réflexivité
Authors: Lagadec Philippe , Le Gall Laurent
Published: November 2023

Depuis le printemps 2021, nous nous entretenons avec des habitants d’une rue de Brest en posant cette question : « Pour vous, qu’est-ce qu’un drapeau ? » Le drapeau se fait alors discours. Discours sur la vie qui défile à travers le choix de certains moments qui, dans une trajectoire, ont été des moments vexillaires. Discours sur les attachements différenciés à la nation entendue peu ou prou à travers ce qui serait son symétrique, la communauté civique. Discours sur les formes de la loyauté à ce que le drapeau est surtout en ses atours nationaux : une « institution de repos » dont la prégnance permet des indifférences proclamées ou des attachements conjoncturels. Compagnonner avec la nation, puisque c’est ce qui nous semble qualifier au mieux les relations qu’entretiennent des individus avec un ordre dont on postule ou l’élision ou la résistance dans un monde mondialisé : tel est, in fine , l’enjeu qui ressort d’une ethnographie soucieuse de comprendre ce que le drapeau dévoile, un espace social qui existe tout autant à travers des positions individuelles qu’à partir de ce que des situations font aux gens.
Évolution des représentations de la famille et soutien à la parentalité
Authors: Neyrand Gérard
Published: November 2023

Au regard d’une famille devenue plurielle sous l’effet des mutations sociales, le soutien à la parentalité se constitue en dispositif au tournant du xxi e siècle, à la suite des initiatives associatives des années 1970-1980 (crèches parentales, lieux d’accueil enfant-parents, médiation familiale, espaces rencontre, groupes de parole…). Il a pour objectif de coordonner et développer les différentes actions d’accompagnement des parents dans leur travail éducatif, mais il est confronté à une diversité de façons de le concevoir selon les acteurs politiques et les politiques familiales et parentales, à l’heure où désormais c’est l’enfant qui fait famille. L’importance de la réflexion éthique devient centrale pour éviter les risques d’un parentalisme éducatif qui se focalise sur les seuls parents et tend à gérer le dispositif de façon managériale.

Familles… honnies, omises, requises… ? Ou les formes du déni en psychiatrie
Authors: Skiredj-Hahn Catherine
Published: November 2023

Le collectif puis l’association Le Fil conducteur psy sont nés de la rencontre de familles, de soignants, de patients lors des assises « Quelle hospitalité pour la folie ? », en 2013, organisées par les CÉMÉA et le Collectif des 39. Durant sept années, les témoignages se sont accumulés. Ces échanges sur le vécu de la maladie, le véritable « travail » des familles et les pratiques de soins sont à lire à la fois comme l’expression d’une expérience partageable et souvent d’une souffrance partagée au sein d’un groupe et le vecteur d’une volonté de distanciation sur les vécus douloureux relatés.
Le secteur médico-social dans les paradoxes du changement
Authors: Le Capitaine Jean-Yves
Published: November 2023

Des changements importants sont en cours dans le fonctionnement des services et l’accompagnement des personnes en situation de handicap, mettant en jeu les acteurs de ce fonctionnement que sont le discours sociétal et les politiques publiques, les organisations de services et les professionnels. Toutefois, ces changements se heurtent à des résistances, dont l’une des causes pourrait se trouver dans les paradoxes mêmes des modalités de mise en oeuvre des changements. En effet, du côté des professionnels, les changements sont opérés de manière unilatérale par les politiques publiques et les organisations, dépouillant les professionnels de toute créativité et tout sens, en les contraignant à adhérer à des représentations, actions et organisations élaborées loin d’eux. Pour lever les obstacles de ces résistances, qui nuisent à la pleine participation des personnes en situation de handicap, il conviendrait de penser autrement l’engagement des professionnels dans la mise en sens de leur action.
Le fantôme du traumatisme
Authors: Germani Stéphanie
Published: November 2023

Un abus sexuel vécu lors de son enfance peut provoquer de terribles troubles psychologiques. Lorsque cet événement est passé sous silence, les effets sont encore plus gravissimes. Le choc est équivalent à l’anéantissement du sentiment de soi, quant au secret, il est une commotion psychique pouvant hanter jusqu’à la vie adulte, prenant la forme d’un fantôme/esprit qui visite et qui tourmente. Nous présenterons monsieur V., un patient incarcéré sous mandat de déport criminel qui a effectué une psychothérapie pendant sa détention. Cette étude de cas laisse entrevoir les mécanismes de défense et les rouages inconscients qui peuvent être à l’œuvre après avoir vécu un traumatisme sexuel tel que le viol.
L’animation socio-sportive : de la Palestine aux « quartiers »
Authors: Segrestan Philippe
Published: November 2023

Les animations dites « socio-sportives » font maintenant partie des leviers éducatifs possibles pour agir dans les quartiers où la vie est difficile. Une équipe de formateurs de la FSGT et des CÉMÉA est impliquée dans un programme destiné aux encadrants des enfants palestiniens vivant dans les camps de réfugiés et les zones C. Ils dégagent de cette action des enseignements qui peuvent être utiles à d’autres situations d’exclusion. Le texte propose une définition de l’animation socio-sportive, il en présente les principales caractéristiques et montre les différences et les similitudes avec les pratiques sportives classiques.
The Individual as an Object of Love: The Property View of Love Meets the Hegelian View of Properties
Authors: Saunders Joe , Stern Robert
Published: November 2023

In this paper, we do two things: first, we offer a metaphysical account of what it is to be an individual person through Hegel’s understanding of the concrete universal; and second, we show how this account of an individual can help in thinking about love. The aim is to show that Hegel’s distinctive account of individuality and universality can do justice to two intuitions about love which appear to be in tension: on the one hand, that love can involve a response to properties that an individual possesses; but on the other hand, what it is to love someone is not just to love their properties, but to love them as the distinct individual they are. We claim that Hegel’s conception of the relation between individuals and their properties, which relies on his account of the concrete universal, can resolve this tension and make sense of this aspect of love.
Exploring the Role of Physical Exercise to Improve Cardiorespiratory Fitness and Muscular Strength Among Individuals With Severe Mental Disorder
Authors: Lopez-Moral Alvaro , Munguia-Izquierdo Diego , Bueno-Antequera Javier
Published: November 2023

Severe mental disorders (SMD) are a major contributor to mortality and one of the five leading causes of disability worldwide. Therefore, it is important to establish strategies aimed at improving the physical health in individuals with these disorders, with the aim of reducing the incidence of chronic diseases and promoting health improvement. Cardiorespiratory fitness and muscle strength, which are often impaired in individuals with severe mental disorders, are complementary and independent variables that are related to mortality risk. For this reason, it is necessary to improve the assessment of these parameters to identify vulnerable situations that require early intervention through physical exercise. This chapter examines the importance of physical fitness as a health factor and presents evidence for different physical exercise interventions aimed at improving physical fitness in individuals with SMD.
Diagnosis of Cardiovascular Diseases by Ensemble Optimization Deep Learning Techniques
Authors: Oyewola David Opeoluwa , Dada Emmanuel Gbenga , Misra Sanjay
Published: November 2023

Cardiovascular disease (CVD) is a variety of diseases that affect the blood vessels and the heart. The authors propose a set of deep learning inspired by the approach used in CVD support centers for the early diagnosis of CVD using deep learning techniques. Data were collected from patients who received CVD screening. The authors propose a prediction model to diagnose whether people have CVD or not and to provide awareness or diagnosis on that. The performance of each algorithm is compared with that of long-, short-time memory, feedforward, and cascade forward neural networks, and Elman neural networks. The results show that the ensemble deep learning classification and prediction model achieved 98.45% accuracy. Using the proposed early diagnosis model for CVD can help simplify the diagnosis of CVD by medical professionals.

Analysis of the Heat Treatment Effect of CsPbBr3 Photoanode on the Photoelectrochemical Performance: Preliminary Results
Authors: Prakoso Ahmad Fahmi , Maheswari Michaela Claresta Erja , Sutarsis Sutarsis , Pramata Azzah Dyah
Published: November 2023

The perovskite CsPbBr3 possesses good photoelectrochemical properties, making it a potential candidate for use as a photoanode. The commonly used photoanode is the FTO/TiO2/CsPbBr3 photoanode in water splitting applications. However, there has been no research conducted on the FTO/TiO2/CsPbBr3 photoanode for the oxidation of glucose derived from abundant biomass sources. This study aims to analyze the influence of heat treatment and glucose concentration on the performance of glucose oxidation, as well as the efficiency of glucose conversion and electricity production. First, CsPbBr3 solution is prepared under vacuum conditions using the Ligand Assisted Reprecipitation (LARP) method. Subsequently, the fabrication process of the FTO/TiO2/CsPbBr3 photoanode is carried out with variations including no heat treatment, heat treatment at a temperature of 110°C, and variations in glucose solution concentrations of 0.2 M and 0.5 M. XRD and SEM tests are conducted to determine the formed phases and morphology of CsPbBr3. The XRD and SEM results confirm the presence of CsPbBr3 phase and the formation of CsPb2Br5 phase due to the heat treatment process. The EIS testing reveals that the heat treatment process induces an oxidation process in the CsPbBr3 perovskite, which can decrease the glucose oxidation performance of the FTO/TiO2/CsPbBr3 photoanode. Based on HPLC analysis, the highest conversion efficiency of glucose is 97.37%, respectively under 110 oC heat treatment and with 0.5 M glucose.

Grey matter and white matter changes in epilepsy detected by Voxel-based morphometry (VBM) and Tensor-based morphometry (TBM) show notable similarities and differences to date. Therefore, a direct comparison of results using VBM and TBM is necessary to understand how different methods are sensitive in detecting structural brain changes in epilepsy. 45 patients with epilepsy (27.62 ±12.8 years old) and 46 healthy controls (34.25 ±16.0 years old) were scanned using a 3 Tesla MRI scanner. T1 weighted brain images were acquired, pre-processed, and further analyzed using Computational Anatomy Toolbox (CAT12). For VBM, voxel-wise grey matter volumes, white matter volumes and cerebrospinal fluid volumes were computed and smoothed (Full width at half maximum, FWHM= 8 mm) for each participant. For TBM, voxel-wise Jacobian determinant images were obtained and smoothed (FWHM= 8 mm). The group differences between patients and healthy controls were obtained using two-sample T-tests. Conjunction analyses were performed to explore the sensitivity of different methods in detecting grey matter and white matter. Our results showed that although both methods detected widespread structural changes, there are similarities and differences in grey matter and white matter findings detected by different methods. Only 35.07 % of grey matter (cerebellum, right temporal gyrus, left cuneus and left superior frontal) were commonly detected by VBM and TBM while only 26.08 % of white matter (anterior lobe of cerebellum, left occipital, frontal, and right temporal regions) were commonly detected by VBM and TBM. Therefore, we conclude that VBM and TBM are differently sensitive in detecting structural brain changes in epilepsy.

Published: November 2023

Big Data Analytics is swiftly growing and has revolutionized the field of business, through advanced analytics. Similarly, Sri Lanka is progressively embracing big data technology and the pioneering adopters include logistics companies. This emerging field has opened up many employment opportunities for big data professionals (BDP). However, Sri Lanka has encountered a shortage of BDP, amidst the significant growth in the field. Thus, this study analyze the factors that potentially impact the employability of BDP in the field of big data analytics, with the motive of finding solutions to reduce the skill shortage, which serves as the main objective of the research. The study was executed by analyzing qualitative and quantitative data collected through a questionnaire survey followed by a series of structured interviews. The questionnaire survey was distributed among 180 employees who are currently employed in the field of big data analytics, whereas, the structured interviews were carried out with 08 experts in the field. Based on the initial Exploratory Factor Analysis conducted, Education Factors, Skills and Competencies, and Job Market Factors were identified as the three main variables which affect the employability of BDP. Subsequently, a Thematic Analysis was carried out in order to investigate the impact of the aforementioned factors on the big data skill shortage, and to navigate possible remedies for it. Based on the data analysis conducted and results derived, it was depicted that the employability of BDP is directly related to Education Factors, Skills and Competencies and Job Market factors. As implications of the study it was revealed that certain educational and competency development factors should be enhanced in order to diminish the skill shortage of BDP.
The Impact of Lean Construction Tools on the Reduction of Contractor-Related Causes of Delay in Sri Lankan Construction Industry
Authors: Kalubovila K. A. O. T. , Kawmudi W. N.
Published: November 2023

Though lean construction is abundantly used in other countries, it is an underrated concept when it comes to Sri Lanka. Past research studies collectively demonstrate that construction industry in Sri Lankan is lagging in the effective implementation of lean in construction processes. Demonstrating the effectiveness of the lean construction tools to mitigate causes of delay will be a future research concern. Since, delays are still taking place within Sri Lanka, it is crucial to look at how lean construction tools can affect to reduce construction delays. This paper aims to identify the impact of Lean Construction Tools (5S, Last Planner System, Visual Management, First Run Studies) on reduction of Contractor related causes of delay. This was met by utilizing a mixed research methodology, which includes both the gathering of quantitative data through a questionnaire survey and the gathering of qualitative data by conducting semi-structured interviews with construction industry specialists. SPSS software was used to analyze data collected from the questionnaire survey, and content analysis was used to examine data obtained from the semi-structured interviews. The results revealed that implementation of Lean Construction Tools can lead to reduction of Contractor related causes of delay. Further, it was disclosed that 5S is the Lean Tool that has the highest impact on reduction of Contractor related delays. Findings have also revealed that lack of awareness about Lean Construction is the most critical challenge for successful implementation of Lean Construction Tools within Sri Lanka. The results depict that in order to overcome this barrier awareness on Lean Construction must be enhanced among construction industry professionals.
A Study on Workload of a Medical Linear Accelerator at a High Throughput Cancer Treatment Centre in Sri Lanka
Authors: Ramanathan V. , Gamage S. C. S. M. , Jayarathna L. W. M. N.
Published: November 2023

Radiotherapy bunker design depends on several factors, and among them, workload is one of the important factors. Workload is calculated from the radiation dose delivered at the isocenter. Due to the introduction of new radiotherapy treatment modalities and an increasing number of new cancer patients, there is a higher possibility to increase the workload. Therefore, this study aims to assess the workload of Varian linear accelerator vault at Apeksha Hospital, Maharagama. Data were collected from 1st of August 2020 to 30th November 2020. Dose delivered at isocenter from the 3D-CRT procedures with 6 MV and 15 MV photon energy, the IMRT procedures with 6 MV photon energy and the quality assurance (QA) procedures were collected from ARIA patient management system and transferred into Excel spread sheet for data analysis. The calculated weekly workload was 2326 Gy/week with a 43% contribution from the IMRT procedures with 6 MV, 39% contribution from the 3D-CDT procedures with 6 MV, 16% contribution from the 3D-CDT procedures with 15 MV and 2% contribution from physics workload (QA procedures). The evaluated workload is higher than the NCRP recommended workload of 1000 Gy/week. This study recommends for at least a one-year survey for more accuracy on workload assessment, and also to evaluate the use factor since most of the advanced radiotherapy treatment techniques use high number of monitor units which will increase the leakage radiation.
Dynamics of Optimal Growth and Overlapping Generations Models in Economic Convergence and Inequality: A Review
Authors: Samaranayake D. I. J.
Published: November 2023

This study explains the dynamics in the Optimal Growth [OGR] and Overlapping Generations [OGE]models and their implications for (real) GDP per capita [RGDPPC] in different countries, short-run and long-run. This analysis uses RGDPPCs for ten countries consisting of five per each developed and developing category for 116 years. Sri Lanka is used as the favourite destination and calculated the RGDPPC ratios. Data on RGDPPC for ten countries explains that the relative differences between RGDPPC ratios and the baseline are varying over time. Also, it demonstrates a high variation in the short-run dynamics between countries. Both models predict a convergence of economies into a steady-state having the same amount of RGDPPCs in the long run. This prediction appears to be acceptable in the analysis. Having Sri Lanka as the benchmark, Japan exhibits low RGDPPC values at the initial stage and eventually gets closer to the RGDPPCs of developed countries. This is not a direct convergence to the steady-state but convergence to the RGDPPC level of developed countries. Also, the concept of efficient contributions by generations in the OGE model was considered and it reflects a more realistic reasoning as per the short-run dynamics, but that resulted in making differences across countries per capita GDP in the long run. The long-run dynamics revealed that growing inequality is a common issue in developing nations as a very low percentage of populations enjoys a high proportion of national output.
Evaluating Occupational Radiation Exposure in Interventional Cardiology: An Investigation into Estimating Effective Dose
Authors: Wickramasinghe Sachini Udara , Ramanathan Vijitha , Sarasanandarajah Sivananthan
Published: November 2023

To safeguard the safety and well-being of interventional cardiology healthcare workers, monitoring their occupational radiation exposure is crucial. This study evaluates the radiation dose of interventional cardiologists using the Swiss Ordinance for personal dosimetry approach. Its primary aim is to estimate the radiation dose for each operator engaged in interventional cardiology procedures to protect from dangerous levels of radiation. Additionally, this study assesses the correlation between under-apron and over-apron dosimeters. Notably, no previous studies in Sri Lanka have specifically assessed radiation dose in this context, making this research vital in shedding light on radiation exposure in an interventional cardiology environment. Two cardiologists conducted a total of 108 interventional cardiology procedures, including coronary angiograms and percutaneous coronary interventions for a month at the cardiac catheterization laboratory of Sri Jayewardenepura General Hospital, Sri Lanka. Active dosimeters were utilized to measure dose values using a two-dosimeter approach where one dosimeter was positioned above the thyroid collar and the other beneath the lead apron on the left side of the waist. The effective doses (E) were determined using the Swiss Ordinance algorithm. Furthermore, this study also examined the relationship between under and over-apron dose values. The Swiss Ordinance algorithm estimated the mean annual E values for each cardiologist, resulting in 3.0397 mSv/year and 0.9697 mSv/year, respectively showing that the estimated annual occupational doses remained well below the annual dose limit (20 mSv/year). The accuracy of the algorithm in interventional ionising radiation scenarios was also highlighted. A strong positive correlation (R2 = 0.9500) was observed between over-apron and under-apron dose values. Applying the Swiss Ordinance for personal dosimetry and studying the link between over and under-apron dosimeters in interventional cardiology improve our grasp of radiation dosimetry. Emphasizing precise dose estimation for the safety of cardiologists, this study enhances the radiation safety practices in interventional cardiology.
False-Positive Rates, Risk Factors, and Interpretations of the Vestibular/Ocular Motor Screening in Collegiate Athletes
Authors: Rosenblum Daniel , Donahue Catherine , Higgins Haven , Brna Madison , Resch Jacob
Published: November 2023

Context

Biological sex and history of motion sickness are known modifiers associated with a false-positive baseline Vestibular/Ocular Motor Screening (VOMS). However, other factors may be associated with a false-positive VOMS in collegiate athletes.

Objective

To identify contributing factors to false-positive VOMS assessments using population-specific criteria. We also critically appraised previously reported interpretation criteria.

Design

Descriptive laboratory study.

Setting

Single-site collegiate athletic training clinic.

Patients or Other Participants

National Collegiate Athletic Association Division I athletes (n = 462 [41% female]) aged 18.8 ± 1.4 years.

Main Outcome Measure(s)

Participants completed the Athlete Sleep Behavior Questionnaire, the 7-Item Generalized Anxiety Index, the Immediate Postconcussion Assessment and Cognitive Testing battery, the Patient Health Questionnaire-9, the Revised Head Injury Scale, the Sensory Organization Test, and the VOMS as part of a multidimensional baseline concussion assessment. Participants were classified into 2 groups based on whether they had a total symptom score of greater than or equal to 8 after VOMS administration, excluding the baseline checklist. We used χ2 and independent t tests to compare group demographics. A binary logistic regression with adjusted odds ratios (ORs) was used to evaluate the influence of sex, corrected vision, attention-deficit/hyperactivity disorder, Immediate Postconcussion Assessment and Cognitive Testing composite scores, concussion history, history of treatment for headache and/or migraine, Generalized Anxiety Index scores, Patient Health Questionnaire-9 scores, Athlete Sleep Behavior Questionnaire scores, and Sensory Organization Test equilibrium scores and somatosensory, visual, and vestibular sensory ratios on false-positive rates.

Results

Approximately 9.1% (42 of 462 [30 females]) met criteria for a false-positive VOMS. A significantly greater proportion of females had false positives (χ21 = 18.37, P < .001). Female sex (OR = 2.79; 95% CI = 1.17, 6.65; P = .02) and history of treatment for headache (OR = 4.99; 95% CI = 1.21, 20.59; P = .026) were the only significant predictors of false-positive VOMS. Depending on cutoff interpretation, false-positive rates using our data ranged from 9.1% to 22.5%.

Conclusions

Our results support the most recent interpretation guidelines for the VOMS in collegiate athletes due to a low false-positive rate and ease of interpretation. Biological sex and history of headaches should be considered when administering the VOMS in the absence of a baseline.
Challenges Faced During Professional Preparation and Transition to Practice Among Diverse Early Professional Athletic Trainers
Authors: Smith Alyssa D. , Moffit Dani M. , Lacayo Candace P. , Bowman Thomas G.
Published: November 2023

Context

Early professional (EP) athletic trainers (ATs) may encounter adjustments and develop individual identities to master a new role, which can be difficult while transitioning from student to autonomous professional. Previous literature lacks content about the transition to practice of credentialed ATs who identify as Black, Indigenous, or people of color (BIPOC).

Objective

To identify challenges during the professional education and transition to practice of EP ATs identifying as BIPOC.

Design

Qualitative study.

Setting

Virtual interviews.

Patients or Other Participants

Fifteen recently credentialed ATs (13 women, 2 men; age = 26.73 ± 1.41 years, experience = 13.80 ± 4.03 months) who self-identified as BIPOC.

Data Collection and Analysis

We used an interview guide, validated by peer (n = 1) and expert (n = 3) review, to structure the data collection sessions. Data saturation guided recruitment, and we achieved theoretical redundancy after the final interview. We analyzed the data with a phenomenological approach and used multianalyst triangulation (n = 2) and peer review (n = 2) as credibility strategies.

Results

All participants mentioned being victims of microaggressions because of their race during either their professional preparation, work environment, or both. Those who chose to report the incidents felt a lack of support from work supervisors, faculty, peers, and preceptors. Participants noted a preference for racially concordant mentoring to facilitate talking to a person who could better understand BIPOC EPs’ experiences. Respondents also relied on outside support from friends and family as coping mechanisms. Finally, participants experienced perceived incompetency from supervisors due to their limited work experience as EPs and felt their professional preparation was stunted by the COVID-19 pandemic.

Conclusions

Participants perceived that their transition to practice was stressful due to the microaggressions encountered, a lack of support, and a lack of racially concordant mentoring.

Context

Psychological skills training improves performance in athletes. However, authors of few studies have looked at the efficacy and satisfaction of mental skills training programs for collegiate athletes.

Objective

To evaluate the satisfaction of collegiate athletes with a 6-session mental skills course and to assess changes in mental toughness and coping skills before and after the course.

Design

Cohort study.

Setting

Division I collegiate athletic teams.

Patients or Other Participants

Fifty-four Division I female athletes (mean age = 19.8 years) participated in the program, and 42 (77.7%) completed precourse assessments, which subsequent evaluations were matched to.

Main Outcome Measure(s)

The Athletic Coping Skills Inventory (ACSI; range, 0–84) and Mental Toughness Index (MTI; range, 8–56) assessed coping skills and mental toughness precourse, immediately postcourse, and 4 months postcourse. Satisfaction was assessed on a 10-point scale.

Results

For participants with paired precourse and immediately postcourse data (n = 37, 68.5%), MTI scores improved by a mean 2.6 points (95% CI = 1.1, 4.1; P = .001), and ACSI scores improved by a mean 4.0 points (95% CI = 0.6, 7.4; P = .02). At the 4-month follow-up (n = 25, 46.2%), no change was detected from precourse in mean MTI score (P = .72), but a significant increase of 3.4 points in mean ACSI (95% CI = 0.4, 6.4; P = .03) occurred. Overall satisfaction had a median score of 9/10 (interquartile range, 8–10) at postcourse, and 18 participants (48.6%) shared positive free-text comments regarding course delivery, content, and impact. No negative feedback was reported.

Conclusions

Mental toughness and coping skills scores significantly improved at postcourse assessment, with coping skills scores maintaining their effect at 4 months. The improvements identified spark the question of the potential impact of mental skills training programs when studied in larger athlete populations or over more sustained periods of time. Athletes reported being highly satisfied with course content and reported overall positive experiences.
An Update on the Diagnosis and Management of Tic Disorders

Tic disorders (TDs) are a group of common neuropsychiatric disorders of childhood and adolescence. TDs may impact the physical, emotional, and social well-being of the affected person. In this review, we present an update on the clinical manifestations, pathophysiology, diagnosis, and treatment of TDs. We searched the PubMed database for articles on tics and Tourette syndrome. More than 400 articles were reviewed, of which 141 are included in this review. TDs are more prevalent in children than in adults and in males than in females. It may result from a complex interaction between various genetic, environmental, and immunological factors. Dysregulation in the cortico-striato-pallido-thalamo-cortical network is the most plausible pathophysiology resulting in tics. TD is a clinical diagnosis based on clinical features and findings on neurological examination, especially the identification of tic phenomenology. In addition to tics, TD patients may have sensory features, including premonitory urge; enhanced and persistent sensitivity to non-noxious external or internal stimuli; and behavioral manifestations, including attention deficit hyperactivity disorders, obsessive-compulsive disorders, and autism spectrum disorders. Clinical findings of hyperkinetic movements that usually mimic tics have been compared and contrasted with those of TD. Patients with TD may not require specific treatment if tics are not distressing. Psychoeducation and supportive therapy can help reduce tics when combined with medication. Dispelling myths and promoting acceptance are important to improve patient outcomes. Using European, Canadian, and American guidelines, the treatment of TD, including behavioral therapy, medical therapy, and emerging/experimental therapy, has been discussed.
Correlation of microvessel density with histopathological parameters of carcinoma breast

Published: November 2023

Background & objectives:

Microvessel density (MVD) is a surrogate measure of tumour angiogenesis, and is well known for over two decades to identify individuals with a high risk of recurrence with greater prevision than traditional markers. This study aims to assess the utility of MVD and its correlation with the Nottingham Prognostic Index (NPI) and other routine histopathological parameters in carcinoma breast.

Methods:

This two year retrospective, cross-sectional and analytical study evaluated 143 women with breast cancer presenting to rural tertiary hospital in central India. These women were graded histopathologically, the immunophenotype was determined using ER (estrogen receptor), PR (progesterone receptor), Her2 neu (human epidermal growth factor receptor 2 neu) and Ki-67 proliferation index (Kiel-67) immunohistochemical markers and anti-CD34 antibody to stain the endothelial cell clusters displaying the microvessels. The NPI was generated for each participant based on the tumour size, histologic grade and involvement of lymph node. The parameters were compared with the CD34 scores. Differential and inferential statistics, including the independent t test, analysis of variance, Pearson’s correlation coefficient, Spearman’s rank correlation coefficient and point biserial correlation coefficient, were used for statistical analysis.

Results:

This study showed that CD34 values ranged from 6-36 microvessels/hpf, with 24.16±6.77 microvessels/hpf as the mean. The mean microvessel counts showed a significant positive correlation with the Bloom–Richardson histological grade, vascular invasion, LN (lymph node) positivity and NPI. However, there was no significant correlation of CD34 values with the participant’s age, tumour size neither any significant association of CD34 values with the individual’s immunophenotype.

Interpretations & conclusions:

A positive linear correlation of the microvessel counts and the NPI scores suggest that with an increase in tumour angiogenesis, there was increased proliferative potential. Based on the significant correlation between the microvessel counts and the vascular invasion of the tumour masses in this study, it can be assumed that there will be vascular invasion if the microvessel count is higher and vice-versa. Although it is established that angiogenesis and neovascularization are required for the expansion of the solid tumour tissue, the heterogeneous nature of this entity makes it difficult for obtaining a linear correlation. Hence, it is suggested that though neovascularization permits advanced tumour spread it, however, does not guarantee it.
Plantar Fasciitis: An Updated Review
Authors: Tseng Wen-Che , Chen Yun-Chang , Lee Tsung-Min , Chen Wen-Shiang
Published: November 2023

Plantar fasciitis (PF) is a common musculoskeletal disease. Histologic findings of patients with PF showed mainly chronic degenerative processes rather than inflammation. In addition to mechanical factors, such as repetitive stress and reduced ankle dorsiflexion, PF is also linked to rheumatologic diseases and genetic factors. Ultrasound is becoming a standard imaging technique for assessing PF. Major sonographic findings included increased plantar fascia thickness and hypoechoic plantar fascia. In addition to traditional B-mode ultrasound, sonoelastography can also be utilized to diagnose PF. Ultrasound can also be used to guide therapeutic interventions. Over 80% of patients with PF improved under nonsurgical treatment. Treatment options for PF include physical therapy, modalities (laser, therapeutic ultrasound), extracorporeal shock wave therapy (ESWT), injections, transcatheter arterial embolization, and surgery. For injections, corticosteroid was mostly used in the past but has been replaced gradually by other techniques such as platelet-rich plasma or dextrose prolotherapy. There is also more and more evidence about ESWT in treating PF. Surgery serves as an option for recalcitrant PF cases, and endoscopic fasciotomy seemed to have good outcomes. Ultrasound plays an important role in diagnosing of PF and evaluating the treatment effect, and the use of sonoelastography in addition to traditional B-mode ultrasound may help in the early detection of PF and assessment of the treatment effect.

Published: November 2023

Mucopolysaccharidosis are group of inherited metabolic diseases caused by the absence or malfunctioning of lysosomal enzymes resulting in accumulation of glycosaminoglycans. Over time this accumulation damages cells, tissues, and organs. There are seven types of MPS and 13 subtypes that are associated with multiple organ systems, such as the respiratory, liver, spleen, central nervous systems, arteries, skeletons, eyes, joints, ears, skin, and/or teeth. The various types share some common ocular features that differ in terms of the severity of the affection. Visual loss in MPS patients is varied and can be due to corneal clouding, glaucoma, retinopathy, and optic neuropathy. The primary focus of this review is on changes in the cornea and anterior segment in MPS patients, including clinical and novel investigative modalities, current surgical management, effects of systemic therapy like hematopoietic stem cell transplants (HSCT)and enzyme replacement therapy (ERT), as well as significant research developments.
