À bout de souffle
Authors: Berton Jacques
Published: November 2023

Dans un contexte d’essoufflement des institutions du travail social, les groupes d’analyses de pratiques deviennent les témoins du malaise de ces institutions ayant subi l’impact d’un contexte sanitaire qui n’a fait que renforcer les fragilités des métiers du travail social. L’incertain constitutif de l’activité imprègne le cadre d’un travail en quête de sens. Ces espaces réflexifs sont aujourd’hui incontournables pour des équipes exténuées, et comme toute soupape, ils peuvent éviter une pression trop importante. Mais la surchauffe est réelle.
Travailleurs sociaux libanais à l’épreuve de l’histoire et de l’altérité
Authors: Matta Houwayda , Chouchani Rita , Salameh Maguy
Published: November 2023

La pratique professionnelle des travailleurs sociaux auprès des populations migrantes expose ces professionnels à des dilemmes majeurs relevant de différents registres. Au Liban, la question des liens interculturels pacifiques entre la population hôte et les déplacés syriens se situe au cœur des préoccupations. Pris dans cette dynamique, les travailleurs sociaux libanais se retrouvent parfois confrontés à leurs propres biais et incertitudes. Ces dilemmes nous ont incité à inviter certains d’entre eux qui travaillent dans ce contexte à faire un retour réflexif sur leurs rapports à cette altérité. Des enjeux profonds issus de cette réflexion interpellent foncièrement la formation.

« Je n’ai pas de papiers donc je ne peux pas faire d’argent. C’est tout. »
Authors: Chappart Pascaline , Lévy-Vroelant Claire
Published: November 2023

Que signifie être « placé en extérieur » lorsque l’on est, comme Ibé, un jeune sans papiers ? À l’enfermement carcéral succède l’enfermement administratif, celui où l’on se heurte aux catégories administratives, à l’impossibilité de travailler légalement, à l’exploitation. Une double peine, en somme. Détresse et lassitude ? Sans conteste, une « envie d’exploser » mais plus encore d’avancer, comme pour tenter de rattraper le temps perdu.
L’internement des personnes d’origine japonaise aux États-Unis
Authors: Morri Johann
Published: November 2023

L’entrée en guerre des États-Unis contre le Japon en 1941 s’est aussi jouée sur le sol américain. Présumées « déloyales », des milliers de personnes d’origine japonaise ont ainsi été déplacées pour être parquées dans des camps d’internement. À partir des années 1960, cette séquence, un temps oubliée, de l’histoire américaine a suscité tout un travail de mémoire, de réparation mais aussi de réhabilitation judiciaires des survivant·es.
Pour une lecture rhétorique du Hasard et la nécessité de Jacques Monod
Authors: Batut-Hourquebie Christine
Published: November 2023

Cette étude présente une lecture rhétorique de l’ouvrage de Jacques Monod, Le Hasard et la nécessité . La nouvelle rhétorique de Chaïm Perelman propose, dans les années 1960, un élargissement du champ d’action de la rhétorique antique à tout discours argumentatif, ce qu’est cet Essai de philosophie naturelle sur la biologie moderne . L’exorde de l’ouvrage laisse d’emblée apparaître que Monod maîtrise les normes rhétoriques mais qu’il en fait usage avec une certaine liberté. La narration, chargée d’exposer les concepts de sa philosophie, présente l’objectivité de la nature comme postulat de toute recherche scientifique et philosophique. Si la démarche argumentative est cohérente, l’exposé des concepts est parfois difficile d’accès, ce qui compromet l’objectif premier de tout discours argumentatif : gagner l’adhésion du plus grand nombre. La réfutation de Monod se focalise sur quelques philosophes, et sur le marxisme en particulier, selon des procédés rhétoriques reposant essentiellement sur les différentes formes de polémiques. Sa confirmation est le cœur de son ouvrage : il y expose les avancées en biologie moléculaire comme autant de preuves de son postulat d’objectivité. Monod en profite, par un habile procédé rhétorique, pour présenter son épistémologie, fondée sur le hasard des mutations et la nécessité de la sélection naturelle. La péroraison donne lieu à une ultime digression où il tente de concilier valeur et vérité dans une éthique de la connaissance. Sortant alors du cadre imposé par les normes de la rhétorique, Monod ne peut convaincre tous ses lecteurs comme le prouve la correspondance qu’il a reçue. Il fait cependant montre de réels talents d’écrivain.
La faiblesse et le pouvoir. Réflexions sur Le Consentement de V. Springora
Authors: Dubreucq Éric
Published: November 2023

Le livre de Vanessa Springora, Le Consentement , donne le récit de la manière dont elle a été séduite, quand elle était adolescente, par un romancier célèbre âgé d’environ cinquante ans. Mais il retrace également les étapes d’une destruction personnelle : séduite, puis dominée et exploitée, la jeune Vanessa tombe sous son emprise et en mourra presque. Son histoire pose de plus un problème intéressant à propos des relations entre adultes et enfants : peut-elle avoir réellement été victime si, comme elle le dit et l’explique, elle a consenti à cette relation ? Celle-ci a bien été une forme de violence extrême qui l’a soumise à une domination totale, mais elle s’est aussi établie en obtenant de la victime son consentement enthousiaste.

Fake news and youngsters’ decision journey: An evaluation of the influence of misinformation on social media
Authors: Kanashina Olga , Huertas Garcia Rubén , Jimenez-Zarco Ana Isabel
Published: November 2023

Purpose: Social media has changed the way users interact with each other, and has become an important part of numerous lives. However, there is an increasing flow of implausible content circulating on social media, which points to the need for some categorization and regulation. This study will examine how the proliferation of fake news on social media impacts students and their choice of university. To answer this question, market research was conducted on the precedents that affect the acceptance of fake news among university students when choosing to study for a master's degree that will help them in their professional careers.Design/methodology/approach: The study used a quantitative method. A parsimonious model of causal relationships was proposed based on scales taken from the literature, assessed by a convenience sample of students, and adjusted by structural equation modelling (SEM).Findings: Results show that the parsimonious model explains 35% of fake news acceptance and that media dependency (ISMD) and parasocial interaction (PSI) are the main direct effects, while perceived media richness (PR) has a significant indirect influence on the attitude towards fake news and, consequently, on its acceptance. Furthermore, fake news literacy plays a correct moderating role with the most relevant source of influence, SNS dependency.Research limitations: A convenience sample was used, and a parsimonious model with three antecedent factors and one mediating factor was proposed. Other social factors could have been considered, including multicultural variables.Practical implications: The results point to students' expressed dependence on social networks as the main factor explaining their attitude towards fake news, negatively moderated by students' level of knowledge about the importance of this phenomenon in social networks. Therefore, it is relevant to promote knowledge about this phenomenon among students to reduce its influence on decision-making processes.Originality/value: This paper provides a novel context for the study of the proliferation of fake news on social networks: the process of choosing a university by students addicted to the news circulating on social media.
Dementia and Postoperative Delirium in Surgical Hip Fracture Patients: Unveiling Contrasting Risk Factors and Implications
Authors: Zhao Yunchuan , Alderden Jenny , Missbrenner Nicolette
Published: November 2023

Postoperative delirium is a serious complication, particularly in older adults with hip fractures. Using the 2019 American College of Surgeons National Surgical Quality Improvement Program data file, we performed multiple regression analyses to compare risk factors for postoperative delirium in hip fracture patients with and without dementia. Preoperative delirium and mobility aid use were common risk factors in both groups. However, differential effects were observed for other factors. Pathological fracture increased delirium risk in patients with dementia but had a protective effect in those without dementia. In patients with dementia, American Society of Anesthesiology score IV/V was identified as a risk factor, whereas advanced age, severe chronic obstructive pulmonary disease, weight loss, sepsis, elevated international normalized ratio, and serum creatinine level were additional risk factors in patients without dementia. These findings enhance our understanding of the complex relationship among dementia, hip fractures, and postoperative delirium. Identifying specific risk factors for each group can inform tailored interventions and preventive strategies. Further research is needed to validate and expand these findings, ultimately improving care and outcomes. [

Nonlinear dynamics of estrogen receptor-positive breast cancer integrating experimental data: A novel spatial modeling approach
Authors: Alnahdi Abeer S. , Idrees Muhammad
Published: November 2023

Oncology research has focused extensively on estrogen hormones and their function in breast cancer proliferation. Mathematical modeling is essential for the analysis and simulation of breast cancers. This research presents a novel approach to examine the therapeutic and inhibitory effects of hormone and estrogen therapies on the onset of breast cancer. Our proposed mathematical model comprises a nonlinear coupled system of partial differential equations, capturing intricate interactions among estrogen, cytotoxic T lymphocytes, dormant cancer cells, and active cancer cells. The model's parameters are meticulously estimated through experimental studies, and we conduct a comprehensive global sensitivity analysis to assess the uncertainty of these parameter values. Remarkably, our findings underscore the pivotal role of hormone therapy in curtailing breast tumor growth by blocking estrogen's influence on cancer cells. Beyond this crucial insight, our proposed model offers an integrated framework to delve into the complexity of tumor progression and immune response under hormone therapy. We employ diverse experimental datasets encompassing gene expression profiles, spatial tumor morphology, and cellular interactions. Integrating multidimensional experimental data with mathematical models enhances our understanding of breast cancer dynamics and paves the way for personalized treatment strategies. Our study advances our comprehension of estrogen receptor-positive breast cancer and exemplifies a transformative approach that merges experimental data with cutting-edge mathematical modeling. This framework promises to illuminate the complexities of cancer progression and therapy, with broad implications for oncology.
Towards Ideal Understanding
Authors: Hubert Mario , Malfatti Federica Isabella
Published: November 2023

What does it take to understand a phenomenon ideally, or to the highest conceivable extent? In this paper, we answer this question by arguing for five necessary conditions for ideal understanding: (i) sufficient representational accuracy, (ii) intelligibility, (iii) sufficient truth, (iv) reasonable endorsement, and (v) fit. Even if one disagrees that there is some form of ideal understanding, these five conditions can be regarded as sufficient conditions for a particularly deep level of understanding. We then argue that grasping, novel predictions, and transparency are not reasonable conditions for ideal understanding.

Authors: Birch-Becaas Susan , Kloppmann-Lambert Claire , Carter-Thomas Shirley , Dressen-Hammouda Dacia , Rowley-Jolivet Elizabeth , Zerrouki Nedjah
Published: November 2023

Researchers are currently encouraged to make their results more accessible and transparent for their peers and to engage wider, lay audiences in science through new digital media. The Campus Iberus digital science action group carried out a first study to investigate how Spanish scientists communicate their work through digital media (Perez-Llantada et al. 2022). As international partners of this action group, members of the GERAS working group Literacies in Academia, Science and the Professions have replicated the online survey across several Higher Education Institutions in France. Here, we report on the results of the survey concerning both STEMM and HSS researchers. The aim is to identify the types of online science communication used by researchers in the French context, especially those targeting wider, non-specialist audiences. The survey results point to disciplinary and gender differences and allow us to analyze the needs of these researchers in terms of developing the necessary language, communication and digital skills to communicate effectively in this context.
Behavioral Change Techniques to Increase Adherence to Physical Activity in Severe Mental Disorders
Authors: Asad-Cabrera Ismael , Borrueco-Sánchez Jesús , López-Sánchez Camilo , Lopez-Moral Alvaro , Munguía-izquierdo Diego , Bueno-Antequera Javier
Published: November 2023

People with severe mental disorders (SMD) coexist with other diseases derived from a lack of physical activity and sedentary lifestyles. Although physical exercise programs can be interesting when it comes to solving this problem, adherence to them is low and the dropout rate is notable, so that these people do not manage to benefit from the positive effects of physical activity. In this sense, encouraging autonomous motivation seems to be the key to achieving greater attendance at training sessions and achieving a stage of change of action or maintenance. To this end, directing attention toward the support and satisfaction of three basic psychological needs (autonomy, competence, and relationships) seems essential. In this endeavor, different behavior change techniques (BCTs) have been successfully used to promote more self-determined motivations and increase physical activity.
A Family's Experiences of Raising a Child Diagnosed With ADHD
Authors: Tasiou Kyriaki , Nikolaou Eleni N.
Published: November 2023

Attention Deficit Hyperactivity Disorder (ADHD) affects people diagnosed with it and their families in many ways. Parents of children with ADHD are likely to face challenges in various aspects of parenting their children. This chapter describes a case study of a family οf a child diagnosed with ADHD living permanently in Kos. The purpose of this study was to explore through in-depth structured interviews how parents perceive and manage the functioning and organisation of their family, the impact of the child's ADHD behaviour on their daily life, the sources of support they receive and their quality of life. The dominant themes identified were that parents perceive the disorder to affect family functioning and quality of life and seek support in order to cope with the difficulties of daily life. Understanding parents' own experiences is of paramount importance to clinical practice because the way a family functions and the sources of support available to them can have a significant impact on the child and the whole family system.

Authors: AlShaikh Muath , Alsemaih Waleed , Alamri Sultan , Ramadan Qusai
Published: November 2023

The rapid proliferation of internet of things (IoT) devices has ushered in a new era of technological development. However, this growth has also exposed these devices to various cybersecurity risks, including command and control (C&C) attacks. C&C attacks involve unauthorized entities taking control of IoT devices to carry out malicious activities. Traditional cybersecurity measures often fall short in addressing these evolving threats. To enhance IoT security and counter C&C threats, this study explores the potential of supervised learning, a subfield of machine learning. Supervised learning, a method that utilizes past data to train machine learning models capable of independently identifying patterns indicative of C&C threats in real time, offers additional protection to IoT networks. This article delves into the advantages and drawbacks of this approach, considering factors such as the need for well-defined labeled datasets, resource constraints of IoT devices, and ethical considerations surrounding data security.

Authors: Manikandan G. , Sam Reuel Samuel , Gilbert Steven Frederick , Srikanth Karthik
Published: November 2023

For over a decade, social networking has been ruling over the internet and plays a vital role in day-to-day life. However, for a new network to survive in this market, exclusivity is a necessity. As a result, the goal of this work is to create a network for hosting and managing volunteering and events. Furthermore, the network will feature a recommendation system to provide users with events based on their interests and preferences according to how they interact with the platform. The proposed system is exclusively meant for event post creation and management and also it focuses on event posts with interactions such as replies, likes, interest, and disinterest options. This system has been implemented and deployed with the title ‘Evento' with the recommendation engine boasting an average purity index of 0.8031 for approximately 30 users. The results for recommendations have been chosen considering purity index and fisher optimization criterion metrics. Based on the experimental results, the proposed social network system with the recommendation engine has been found to be sufficient.

Effect of Time and Sex on Post–Anterior Cruciate Ligament Reconstruction Psychological Patient-Reported Outcome Measure Scores
Authors: Barth Tiffany , Bond Colin W. , MacFadden Lisa N. , Skelley Nathan W. , Combs Josefine , Noonan Benjamin C.
Published: November 2023

Context

Low scores on psychological patient-reported outcomes measures, including the Anterior Cruciate Ligament—Return to Sport After Injury (ACL-RSI) and Injury-Psychological Readiness to Return to Sport (I-PRRS), after anterior cruciate ligament reconstruction (ACLR) have been associated with a maladaptive psychological response to injury and poor prognosis.

Objective

To assess the effect of time post-ACLR and sex on ACL-RSI and I-PRRS scores and generate normative reference curves.

Design

Case series.

Setting

Outpatient sports medicine and orthopaedic clinic.

Patients or Other Participants

A total of 507 patients (age at ACLR, 17.9 ± 3.0 years) who had undergone primary ACLR and completed ACL-RSI or I-PRRS assessments ≥1 times (n = 796) between 0 and 1 year post-ACLR.

Main Outcome Measure(s)

An honest broker provided anonymous data from our institution’s knee-injury clinical database. Generalized additive models for location, scale, and shape and generalized least-squares analyses were used to assess the effect of time post-ACLR and sex on ACL-RSI and I-PRRS scores.

Results

The ACL-RSI and I-PRRS scores increased over time post-ACLR. Males had higher scores than females until approximately 5 months post-ACLR, with scores converging thereafter.

Conclusions

Males reported higher ACL-RSI and I-PRRS scores than females in the initial stages of rehabilitation, but scores converged between sexes at times associated with return to play post-ACLR. Normative reference curves can be used to objectively appraise ACL-RSI and I-PRRS scores at any time post-ACLR. This may lead to timely recognition of patients with a maladaptive psychological response to injury and a higher likelihood of a poor prognosis, optimizing ACLR outcomes.
Concussion Symptomatology by Symptom Resolution Time in US High School Athletes: Findings From the National Athletic Treatment, Injury and Outcomes Network High School Surveillance Program (NATION-SP)
Authors: Didner Nina , Boltz Adrian J. , Robison Hannah J. , Chandran Avinash , Quinsey Carolyn
Published: November 2023

Context

Concussions incurred during high school athletics are a significant health concern, and studies examining concussions with a symptom resolution time (SRT) of 15 to 28 days have been limited.

Objective

To compare concussions that had an SRT of 15 to 28 days with concussions that had an SRT of greater than 28 days among US high school athletes.

Design

Descriptive epidemiology study.

Setting

Secondary school athletic training clinics.

Patients or Other Participants

Secondary school athletes.

Main Outcome Measure(s)

Concussion frequency, symptom number, and symptom prevalence.

Results

Among all 917 reported concussions (of which 50.8% had missing SRT), 88 had an SRT recorded as 15 to 28 days, and 29 had an SRT recorded as greater than 28 days. Greater frequencies of concussions with an SRT of 15 days or more were reported in boys’ sports (n = 78) than girls’ sports (n = 39). Boys’ football (51.7%) and girls’ basketball (11.5%) accounted for the largest proportions of all reported concussions with an SRT of 15 to 28 days; boys’ football (58.6%) accounted for the greatest proportion of concussions reported with an SRT greater than 28 days. The average number of symptoms was 6.3 ± 3.4 for concussions with an SRT of 15 to 28 days and 7.2 ± 3.8 for those with an SRT greater than 28 days. The most frequently reported symptoms in concussions with both SRT of 15 to 28 days and greater than 28 days were headache, dizziness, sensitivity to light, and difficulty concentrating. The prevalence of irritability was higher in concussions with an SRT of 15 to 28 days as compared with concussions with an SRT greater than 28 days (26.1% versus 13.8%); visual problems (48.3% versus 35.2%) and hyperexcitability (24.1% versus 15.9%) were more prevalent in concussions with an SRT greater than 28 days, although differences were not statistically significant.

Conclusions

Symptom prevalence and total count were comparable between concussions with an SRT of 15 to 28 days and those with an SRT of greater than 28 days with no statistically significant difference, suggesting that symptom burdens within these groups are more similar than they are different.
Social Support, Stress, and Mental Health: Examining the Stress-Buffering Hypothesis in Adolescent Football Athletes
Authors: Delfin Danae , Wallace Jessica , Baez Shelby , Karr Justin E. , Terry Douglas P. , Hibbler Tamaria , Yengo-Kahn Aaron , Newman Sharlene
Published: November 2023

Context

Football sport participation has been linked to both positive and negative effects on overall health. Social support, a network that provides individuals with resources to cope effectively, may positively influence one’s stress and mental health. However, little research has been conducted on adolescent football players.

Objective

To examine the relationships among social support, psychological stress, and mental health in adolescent football athletes.

Design

Cross-sectional study.

Setting

High school athletes during the precompetitive and postcompetitive football season in rural Alabama.

Patients or Other Participants

Black and African American adolescent athletes (N = 93) competing for a school-sponsored football team.

Main Outcome Measure(s)

After a competitive season, participants completed a battery of social support, psychological stress, and mental health symptom measures using the National Institutes of Health Toolbox Application and Patient-Reported Outcomes Measurement Information System. The T-score means, Pearson correlations, and multiple regression analyses were calculated.

Results

Social support was negatively correlated with psychological stress (emotional support, r = −0.386; family relationships, r = −0.412; peer relationships, r = −0.265) and mental health (depression, r = −0.367 and r = −0.323 for emotional support and family relationships, respectively), whereas psychological stress and mental health (depression, r = 0.751; anxiety, r = 0.732) were positively correlated. In regression analyses, social support measures (ie, emotional support, family relationships, and peer relationships) were used to predict psychological stress (F = 7.094, P < .001, R2 = 0.191), depression symptoms (F = 5.323, P < .001, R2 = 0.151), and anxiety symptoms (F = 1.644, P = .190, R2 = 0.052).

Conclusions

In line with the stress-buffering hypothesis, social support in the form of family relationships and overall emotional support garnered through sport participation may reduce psychological stress and help to preserve the mental health of football athletes. These findings indicate that perceived social support may act as a positive resource for the coping of Black and African American adolescent athletes. Further research is warranted to understand the effects of stress and social support on the mental health of adolescents, particularly racial and ethnic minorities who are underrepresented in the athletic training literature.
Lower Extremity Muscle Volume in Unilateral and Bilateral Patellofemoral Pain: A Cross-Sectional Exploratory Study Including Superficial and Deep Muscles
Authors: Kim Sungwan , Park Jihong , Boling Michelle C. , Glaviano Neal R.
Published: November 2023

Context

Existing patellofemoral pain (PFP) literature has primarily been focused on quadriceps muscle volume, with limited attention given to the deep and superficial muscle volume of the lower limbs in individuals with unilateral and bilateral PFP. In this paper, we aim to fill this gap.

Objective

To explore superficial and deep lower extremity muscle volume in women with unilateral or bilateral PFP compared with a normative database of pain-free women.

Design

Cross-sectional study.

Setting

University imaging research center.

Patients or Other Participants

Twenty women with PFP (10 unilateral and 10 bilateral) and 8 pain-free women from a normative database.

Main Outcome Measure(s)

We quantified lower extremity muscle volume via 3.0-T magnetic resonance imaging. Two separate 1-way analyses of variance were performed: (1) unilateral PFP (painful versus nonpainful limb) versus pain-free control groups and (2) bilateral PFP (more painful versus less painful limb) versus pain-free control groups.

Results

We observed no differences in age and body mass index across groups (P > .05). Compared with the pain-free group, the unilateral and bilateral PFP groups had bilaterally smaller volumes of the anterior (iliacus: P ≤ .0004; d range, 2.12–2.65), medial (adductor brevis, adductor longus, gracilis, and pectineus: P ≤ .02; d range, 1.25–2.48), posterior (obturator externus, obturator internus, and quadratus femoris: P < .05; d range, 1.17–4.82), and lateral (gluteus minimus: P ≤ .03; d range, 1.16–2.09) hip muscles and knee extensors (rectus femoris: P ≤ .003; d range, 1.67–2.16) and flexors (long and short head of the biceps femoris: P ≤ .01, d range, 1.56–1.93).

Conclusions

Women with unilateral and those with bilateral PFP displayed less volume of multiple superficial and deep muscles of the bilateral hips and knees than pain-free women. Interventions should bilaterally target lower limb muscles when treating PFP, and hypertrophy exercises for specific muscles should be explored to increase choices for intervention.
Muslim Collegiate Student-Athletes’ Experience With Fasting During Ramadan While Participating in Sport
Authors: Amjad Mishaal , Cavallario Julie M. , Harris Nicolette A. , Welch Bacon Cailee E.
Published: November 2023

Context

As colleges and universities continue to focus on creating diverse, equitable, and inclusive environments, it is important to gain more knowledge on the experiences that Muslim student-athletes have while fasting during the month of Ramadan. Although previous researchers have investigated the physical effects of fasting on the body, little is known about the challenges or support Muslim student-athletes experience while fasting and participating in sport during Ramadan.

Objective

To explore the experiences of Muslim collegiate student-athletes regarding fasting during Ramadan while participating in sports.

Design

Qualitative research study.

Setting

Individual video interviews.

Patients or Other Participants

Twelve Muslim collegiate student-athletes (4 women, 8 men; age = 19.9 ± 1.4 years) from 7 universities across 7 states were interviewed.

Data Collection and Analysis

A semistructured interview guide consisting of questions pertaining to the Muslim student-athletes’ beliefs, challenges, experiences, and feelings was developed to gather perceptions of fasting during Ramadan while participating in sport. Data were analyzed by a multianalyst research team and coded into common themes and categories via a multiphase consensus process.

Results

Four major themes emerged from the interview process: the significance of fasting and Ramadan (familial influence, religious belief, and introspection and spiritual growth), intrinsic challenges (physical challenges, mental and emotional challenges, and time constraints), extrinsic challenges (lack of available resources, knowledge and curiosity of others, and lack of understanding by others), and various types of support (sport-specific support, community support, and desired support) that affected athletes’ experiences with fasting during Ramadan while participating in sport.

Conclusions

The athletic community should seek to better support Muslim student-athletes and respect the importance of fasting during Ramadan. Parties interested in the success of these athletes in sport should improve their understanding regarding Ramadan and the desired support of Muslim student-athletes during fasting.
Modulation of semaphorin 3C & 4D expression in cancerous tissues from individuals with laryngeal squamous cell carcinoma
Authors: Sajadian Marzieh , Khademi Bijan , Moinzadeh Leila , Ghaderi Abbas , Jafarzadeh Abdollah , Razmkhah Mahboobeh
Published: November 2023

Background & objectives:

Semaphorins were initially characterized as axon guidance factors but were subsequently implicated in the regulation of immune responses, angiogenesis, organ formation and a variety of other physiological and developmental functions. Various semaphorins enhance or inhibit tumour progression through different mechanisms. The objective of this study was to assess the expression of various semaphorins and vascular endothelial growth factor (VEGF) gene transcripts as well as the serum level of Sema3A in individuals with laryngeal squamous cell carcinoma (LSCC).

Methods:

Tissue expression of Sema3A, Sema3C, Sema4D, Sema6D and VEGF was determined in both tumour tissues and tissues around the tumour from 30 individuals with pathologically confirmed LSCC using quantitative real-time PCR. Furthermore, the serum level of Sema3A in these individuals was assessed using enzyme-linked immunosorbent assay.

Results:

Sema3C gene transcript showed a significant increase (P=0.001), while Sema4D was observed with a significant decrease in tumour samples compared to non-tumoural tissues (P≤0.01). The expression of the Sema3C gene was found to be associated with the stage of LSCC tumour as it was statistically significant for tumours with stage IV (P<0.01). The serum level of Sema3A was not found to be significant between cases and controls.

Interpretation & conclusions:

Increased expression of Sema3C but decreased expression of Sema4D in tumour tissue of LSCC may introduce these two growth factors as crucial mediators orchestrating tumour growth in individuals with LSCC. This result could open a new vision for the treatment of this malignancy.

Background & objectives:

Despite several adversities imposed by the COVID-19 pandemic, it was crucial to sustain research having public health relevance such as investigations around sickle cell disease (SCD). Against this background, an ongoing ICMR-multicentric study for newborn screening of SCD in the tribal population at Model Rural Health Research Unit (MRHRU-Dahanu) in Palghar District, Maharashtra constituted the current study setting. This was a descriptive study wherein, certain measures were undertaken and strategies were developed in view of the challenges in newborn screening for SCD due to the COVID-19 pandemic during December 2019-September 2021 at Sub District Hospital, MRHRU-Dahanu.

Methods:

During the onset of the pandemic, (December 2019-March 2020), the follow up was possible in 26.7 per cent (20/75) of the newborns. Subsequently, challenges such as travel restrictions, fear of COVID-19, shortage of staff were experienced with respect to enrolment and follow up visits.

Results:

After implementing certain pragmatic strategies (ASHA involvement, usage of virtual platform and flexible visits), follow up rate increased to 47.5 per cent (66/139) between July 2020-April 2021 (post first lockdown) and to 66 per cent (65/98) during the second wave (May 2021-August 2021).

Interpretation & conclusions:

The study emphasizes the importance of network building, use of virtual platform and engaging health workers in tribal settings. Such pragmatic approaches have the potential to pave a path for further implementation research involving specific interventions to improve health outcomes in tribal settings.

Published: November 2023

Electrical vertical takeoff and landing (eVTOL) vehicles for urban air mobility
(UAM) are garnering increased attention from both the automotive and aerospace
industries, with use cases ranging from individual transportation, public
service, cargo delivery, and more. Distributed electric propulsion systems are
their main technical feature; they determine vehicle size and propulsion
efficiency and provide distributed thrust to achieve attitude control.
Considering the intended role of eVTOL vehicles, ducted-fan systems are ideal
choice for the propulsor, as the duct provides a physical barrier between the
rotating blades and the human, especially during the take-off and landing
phases.

Key Technology Challenges of Electric Ducted Fan Propulsion Systems for
eVTOL introduces the main bottlenecks and key enablers of ducted-fan
propulsion systems for eVTOL applications. Based on the introduction and
discussion of these important issues, this report will help eVTOL engineers
understand the key technical issues and inspire them to develop the ideal
solutions that will enable eVTOL vehicle deployment for UAM operations.
