Abstract: Labor export is an activity that greatly contributes to the economic development of Vietnam. However, when returning to the locality, employees and their families have to bear many socio-economic impacts. A cross-sectional study was carried out on 210 families with 916 members of employees going to work abroad, in order to: (1) describe the living conditions of the family of the migrant worker and (2) evaluate the economic and social impacts on employees returning to their localities after working abroad for a definite time. Research results show that employees contribute a lot to the family (54.7%). And the supports are used to help relatives (89%), daily expenses (77.1%), debt repayment (60.5%), shopping for furniture (51.4%) and sending savings (41.9%). Employees still regularly contact family members (99.5%) by phone (97.1%) to discuss issues: Health care (99.5%), information about work employment/production (73.9%) and education (70.5%). Households have almost no problems while the expatriate is abroad. The households all have good living conditions and all have the necessary items for life. Workers who go to work abroad have contributed a lot to their families. Health care; Information about work/production and education are issues frequently discussed by expatriates with their families.

Objective: This study aims to identify barriers and propose appropriate policies and solutions to support reintegration of international migrant workers as returning to their localities. Methods: We used a mixed-method cross-sectional study with 320 workers (quantitative questionnaire) and stakeholders (in-depth interviews). Results: Most workers did not have difficulty in reintegrating into their families and communities after their labour export. 71.2% had no vocational training before exporting and 32.5% found difficulty to seek a job due to their lack of concrete skills; - 13 - only 37.2% had a job the same as previous job oversea. The local government did not have an appropriate strategy for consulting, orientation and vocational training to promote this human resource of export workers. Conclusion: Our study made recommendations in terms of human management, vocational training according to the capacity and needs of the labor export market and the local market. Keywords: international migrant workers, labour export, reintegration, vocational training
The Bible and Public Theology in African Christianity
Authors: Opuni-Frimpong Kwabena
Published: June 2023

The study examined the place of the Bible in the search for theological insights and perspectives for Public Theology in African Christianity. The paper argued that the acceptance of the application of the Bible to human experiences in African societies offer Africa Public theologians the opportunity to apply biblical and theological perspectives to cultural, social, economic, political, and public-policy issues. The study observed that the Bible has been used to promote social justice, advocate for human rights and confront corruption and other forms of oppression. African theologians have developed perspectives on these issues that draw on the biblical teachings of justice, compassion, and stewardship of the earth. The Bible has been a relevant tool for African Christians to engage with public issues, promote social justice, and advocate for the common good. The study concluded with the recommendation that African Christians must engage the social, political, and economic issues that affect their communities, and work for the liberation of all people from the forces that oppress them with Christian teachings and insights. Public Theology in African Christianity must be grounded in a deep commitment to the presence of God in the world, the transformation of society, the liberation of the oppressed, and the contextualization of the Christian faith to the African context. The gospel message has relevance for all aspects of life, including social, political, and economic issues. Theological insights and perspectives that must inform Public Theology in African Christianity include the incarnation, righteousness, social justice, human dignity, Christianity identity, contextualization, and the common good.

Authors: Gestri Giovanni , Pierini Brunello , D’Antraccoli Marco , Bernardini Andrea , Peruzzi Lorenzo
Published: June 2023

We present an updated list of the vascular flora occurring in the Cerbaie hills (Tuscany), a site of high naturalistic interest. The list is based on a literature survey and on field studies carried out in the years 2010–2022. The Cerbaie hills host a flora of 1,107 specific and subspecific taxa (including 100 naturalized aliens), 32 casual aliens and 10 hybrid taxa. Two taxa are new for Tuscany: Carex oedipostyla and Thalictrum simplex subsp. galioides; 330 taxa are new for the study area. Concerning old records, 344 have been confirmed, while 47 were not confirmed, albeit considered reliable. Moreover, we considered three taxa as locally extinct, 19 as doubtfully occurring, and three as wrongly reported. Despite the low elevation of the study area, life forms and chorotypes show marked Eurosiberian affinities, in agreement with the temperate and continental climate.

Cette étude explore la mise en place d’une communauté de marchands roumains de Braşov (Kronstadt), une ville située dans l’empire d’Autriche à la frontière avec la province ottomane mais autonome de Valachie. Ce nœud commercial et cosmopolitain joue un rôle de pont entre l’est et l’ouest de l’Europe, facilitant la circulation des personnes et des biens entre deux contextes culturels différents. C’est dans ce cadre que la communauté des marchands roumains de Schei, un quartier of Braşov, a développé des stratégies d’adaptation sociale tout en travaillant à s’accroître comme groupe socio-professionnel et à étendre ses réseaux commerciaux. Les stratégies d’adaptation au cadre légal prenaient en compte non seulement l’appartenance relide richesse et les capacités économiques de gieuses mais aussi les liens familiaux, le niveau chaque individu.
Le jeu thérapeutique au service de l’ object-presenting
Authors: Cherni Sana , Smida Samia
Published: June 2023

Le traumatisme est un concept pluriel qui se conjugue au rythme de ses origines et qui épouse les variations des tableaux cliniques qu’il entraîne. Lorsqu’il est précoce, nous parlons de trauma. Ce dernier affecte le narcissisme infantile, soit sur le plan identitaire, soit sur le plan identificatoire. La conception winnicottienne du traumatisme, selon laquelle ce dernier est le résultat de « l’échec » d’une relation de dépendance, s’articule parfaitement avec notre étude de cas. En effet, il s’agit de la clinique des fonctions maternelles primaires et plus particulièrement de la clinique de l’ object-presenting . L’hypothèse est que l’échec de la relation de dépendance entraîne l’échec de la fonction de l’ object-presenting autour de laquelle va se construire le dispositif thérapeutique. Ce dispositif doit offrir l’illusion de l’omnipotence afin que l’enfant devienne un sujet actif, désirant et créatif.

El `redescubrimiento´ de los tapices de Pastrana en el siglo XX y su contribución a la construcción de la identidad artística y del discurso nacionalista en Portugal
Authors: Moura Soares Clara
Published: June 2023

Debido a su extraordinario valor histórico y artístico, los tapices de Pastrana, concebidos en el reinado de Alfonso V de Portugal, constituyen un tema de gran interés para historiadores e historiadores del arte. En este artículo el análisis se centra en el siglo XX y en la forma como esos tapices fueron “redescubiertos”, estudiados, divulgados y valorados en Portugal dentro de un contexto histórico y político marcado por el deseo de construir una identidad artística y por la exacerbación del discurso nacionalista. Con estas coordenadas, serán evaluados los efectos que resultaron del conocimiento de los tapices originales, así como la sorprendente recepción crítica que merecieron las réplicas realizadas en la Real Fábrica de Tapices de Madrid, adquiridas por el gobierno portugués en 1953 y expuestas desde entonces en el Palacio de los Duques de Guimarães.

Published: June 2023

This debate article aims to promote a historiographical discussion on the place of Africa in Atlantic and imperial history. The debate revolves around a set of questions: how to bring Africa to the centre of historical research? How close or how distant is the historiography that focuses on the African continent and the one that deals with the African diasporas? What has been the contribution of Portuguese scholarship to the study of precolonial African history? What is the meaning and usefulness of “Lusophone Africa” as a concept and as a field of study? What future for research on precolonial Africa in terms of constraints, opportunities, and priorities? The three historians invited to this roundtable do not provide definitive answers to these questions, but they open the way for a deeper reflection.
A polícia em Portugal no século XVIII: ambiguidades e equívocos
Authors: Abreu Laurinda
Published: June 2023

O alvará de 25 de junho de 1760, que criou o cargo de Intendente-Geral da Polícia da Corte e do Reino, e não uma Intendência-Geral da Polícia como comummente é referido, tem sido apresentado como uma importante inovação do governo do conde de Oeiras, um instrumento do estado de polícia que se começava a formar. Sem questionar a dimensão das transformações políticas em curso, defende-se neste texto que o documento em causa, ancorado num quadro legal circunscrito e pouco inovador, não provocou os efeitos disruptivos que lhe têm sido atribuídos, nem colocou Portugal, no que à polícia concerne, ao lado das “cortes mais polidas” que no dito diploma o governo afirmava querer emular. Defende-se, ainda, que mudanças substantivas na atuação da polícia da corte e do reino só terão ocorrido a partir de 1780, num ambiente de contestação, mas, também, de persistência da indefinição das competências do seu intendente.

Authors: Barbosa José Luís dos Santos
Published: June 2023

A presente investigação estuda o processo de arrecadação e gestão de um imposto régio, o real de água, em Coimbra. A questão central de investigação incide na análise da estrutura periférica responsável por esta arrecadação e gestão, entre 1772 e 1836, tendo em conta que o município foi afastado desta responsabilidade em 1672. Desta forma, o estudo examina os modelos de coleta do imposto, a estrutura periférica da fazenda real que operou em Coimbra e o destino do dinheiro arrecadado. Pretende-se igualmente apurar, com base no contrato de 1790-93, o saldo líquido dos contratadores da renda depois de deduzidos os custos de cobrança e o montante devido à coroa pelo contrato. O núcleo documental utilizado é diversificado e corresponde a livros de receita e despesa, compilações de legislação e de correspondência e registos de arrematações.
A morte aparente e a verificação dos óbitos na medicina brasileira do século XIX
Authors: Abreu Jean Luiz Neves
Published: June 2023

No decorrer dos séculos XVIII e XIX, desenvolveu-se em vários países uma nova sensibilidade sobre a morte. Além de constatar o perigo que os cadáveres representavam para a saúde, a medicina procurou também definir melhor os limites entre a vida e a morte. As denúncias sobre pessoas enterradas ainda com sinais de vida levantavam o problema da morte aparente e a necessidade de os médicos identificarem com maior exatidão os sinais da morte no corpo. Este artigo examina a questão da morte aparente, através dos jornais médicos e de outros documentos, no contexto do Rio de Janeiro (Brasil) do século XIX. Após apresentar os aspectos mais gerais a propósito do debate sobre a morte aparente na medicina da época e suas implicações, destacando o exemplo de Portugal, buscamos contemplar esse debate no caso brasileiro.
Normalisation internationale de la gouvernance numérique des systèmes de mobilité durable : enjeux et perspectives

Published: June 2023

Les normes étant d’excellents lieux d’observation prospective à moyen et à long terme, cet article rend compte des travaux en cours au sein d’un groupe de travail coordonné par la France, sur la gouvernance numérique des systèmes de mobilité durable. L’enjeu pour ce groupe de travail français est de définir un cadre de référence normatif pour ce domaine en devenir afin d’en faciliter le développement pré-concurrentiel. Il s’agit notamment d’en identifier les besoins de haut niveau, mais aussi et surtout, de penser une gouvernance numérique élargie de ces systèmes de mobilité en appui sur une démarche systémique. En effet, d’autres domaines d’action de politique publique – comme l’éducation, la santé, la production, la consommation durable et leurs disciplines scientifiques afférentes – doivent pouvoir contribuer à répondre de manière intégrée, c’est-à-dire complémentaire et coordonnée, à ces besoins de haut niveau, fondamentalement inscrits dans les finalités du développement durable. La difficulté à atteindre un consensus dans ce groupe de travail achoppe notamment sur la difficulté à mettre en œuvre une approche systémique de la gouvernance numérique des systèmes de mobilité.

Engaging Counseling Students in Sustainable Advocacy
Authors: Muzacz Arien K. , LaGue April
Published: June 2023

In addition to instructing students in social justice counseling and advocacy competencies, counselor educators also serve as mentors for aspiring advocates by exemplifying their commitment to the profession as counselors, advocates, and academics. The main point of this chapter will describe an example of an experiential, field-based, service-learning project that students complete in their second year of a part-time master's in counseling degree with a hybrid learning format. Additionally, an overview of the S-Quad framework for social justice advocacy will be provided. This serves as a template for inclusive advocacy that educators can modify to be applicable when working in any program and within a variety of teaching modalities (i.e., synchronous, asynchronous, or hybrid). The final section of this chapter will include an analysis of current challenges to educator sustainability fostered by sociopolitical factors and manifestations of systemic oppression found in educational systems.

Published: June 2023

Despite the growing importance of educating business and management students about sustainability, little is known about the characteristics of different student segments in terms of their perceptions of the educational techniques used for sustainability training. This chapter proposes to profile university students based on their perceptions of sustainability education techniques and investigates whether they are significantly different in terms of socio-demographic and academic characteristics and their attitudes toward sustainability. With the use of cluster analysis of 432 students at a major Spanish university, three clusters were identified with significant differences in terms of perceptions and attitudes towards sustainability education techniques. Additionally, findings showed differences in the formation of the clusters according to the belonging bachelor's degrees. The study suggests that student segmentation based on these factors is appropriate, and thus academic and practical implications are discussed.

Published: June 2023

Parental involvement is widely considered an important aspect of children's educational success, and even more so with children with chronic diseases. However, research indicates that poor parental involvement is the biggest challenge in South African schools, and little attention has been given to identifying barriers to the parent's involvement in the education of children with epilepsy in South African schools. This chapter aims to explore the barriers to parental involvement in the education of children living with epilepsy. It begins the discussion with a background and outlining the benefits of parental involvement focusing on the education of children living with epilepsy; then identifies the causes of non-involvement of parents in the education of children living with epilepsy; and concludes by providing recommendations for enhancing the involvement of parents in the education of epileptic children.

This case study highlights a few prominent cognitive biases influencing investor behavior in India during the COVID-19 pandemic. Financial decisions of an investor are affected by cognitive factors and not just knowledge. Decision-making is not always necessarily rational by nature. Investors are inclined towards irrational decision making quite frequently due to the impact of various cognitive factors. Moreover, the ongoing COVID-19 pandemic has made situations around us extremely precarious. Every business segment has been affected by it, including financial markets. This case study emphasizes significant cognitive biases faced by Stella while investing her and her clients' hard-earned money in the Indian capital markets and expanding her business during COVID-19. She had numerous thoughts and questions in her mind while going through the investment and expansion process ranging from investment amount and options available at her disposal to the level of risk and return involved in each of them. Such apprehensions are also faced by several other investors in India and the world.
Analytical and Experimental Study for Vibration of Laminated Rectangular Plates with Point Masses
Authors: Honda Shinya , Sasakir Katsuhiko , Narita Yoshihiro
Published: June 2023

An analytical method is presented for free vibration of a symmetrically laminated rectangular plate with point masses, and experimental modal analysis is conducted to compare both sets of the frequency data. The problem is solved by an extending Ritz method to include kinetic energy caused by added point masses under any sets of edge conditions, and a frequency equation is derived by minimizing the energy functional. In numerical computation, the accuracy of the solution is studied by convergence test and comparison with the existing result in the specific case. Then, the experimental modal analysis is applied to measure the natural frequencies and mode shapes. The two sets of results are compared, and the validity of both theoretical and experimental approaches is established.
The Critical Load on Quadrilateral and Circular Hollow Pipes under Pure Bending and Pure Torsion

Published: June 2023

Instability is one of the factors causing damage and injury that results in permanent disability. To increase the stable load-carrying capacity, a simplified and efficient computational method for determining the first critical load is necessary for the structure's structural design, application and safety. This study aims to determine the characteristics of the critical bending moment Mbcr and the critical torsion moment MTcr due to geometric size variations in the square, diamond, and circle cross-sectional hollow pipes so that consideration of the selection of hollow pipe size and cross-sectional shape is obtained under pure bending and pure torsion to minimize the occurrence of instability of the structure. The geometric size variation is carried out by changing the value of a/t in the quadrilateral pipe, the value of D/t in the circular pipe, and the length of the pipe L in each cross-sectional shape. This research was conducted using Finite Element Analysis-based software with linear and nonlinear buckling analyses. The moment load is given at the centre point of the model end, and the boundary conditions are set to see the deformation on the mid-span section of the pipe. The results showed that Mbcr and MTcr were inversely proportional to the values of a/t, D/t, and . The largest value of Mbcr belongs to the circular pipe. The value of Mbcr in the diamond pipe is greater than the square pipe but getting closer to the same as the value of L increases the MTcr value of both cross-sections is the same. The MTcr curve in the cross-section of the circle has a higher degree of steepness than the square and diamond cross-section. At the same value, the more the value of a/t and D/t increases thickness change has more compared to the circular pipe. At the same L, the greater the value of a/t and D/t, the difference in the Mbcr between the cross-section of the circle and the quadrilateral is smaller, but the difference in MTcr tends to be the same. At the same value of a/t and D/t, the oval deformation value and angle of twist will get bigger, but the Mbcr and MTcr values are getting smaller and will be constant at a given pipe length.

Published: June 2023

Activation of the complement system represents an important effector mechanism of endogenous and therapeutic Abs. However, efficient complement activation is restricted to a subset of Abs due to the requirement of multivalent interactions between the Ab Fc regions and the C1 complex. In the present study, we demonstrate that Fc-independent recruitment of C1 by modular bispecific single-domain Abs that simultaneously bind C1q and a surface Ag can potently activate the complement system. Using Ags from hematological and solid tumors, we show that these bispecific Abs are cytotoxic to human tumor cell lines that express the Ag and that the modular design allows a functional exchange of the targeting moiety. Direct comparison with clinically approved Abs demonstrates a superior ability of the bispecific Abs to induce complement-dependent cytotoxicity. The efficacy of the bispecific Abs to activate complement strongly depends on the epitope of the C1q binding Ab, demonstrating that the spatial orientation of the C1 complex upon Ag engagement is a critical factor for efficient complement activation. Collectively, our data provide insight into the mechanism of complement activation and provide a new platform for the development of immunotherapies.
Airbus Helicopters Takes Technical Support to New Heights using AI-Powered Search Platform
Authors:   Airbus Helicopters, Antoine Frederic
Published: June 2023

To maintain and operate their helicopters, customers may need Airbus Helicopters technical support. The increase of technical requests addressed by the customers is in relation with the increase of the global fleet. But the sizing of Airbus Helicopters technical support teams cannot be increased the same way. The project was to analyze how the current Artificial Intelligence features could help Airbus Helicopters to be more efficient to manage its customers' technical requests. A search application was developed using Natural Language Processing technology to search more rapidly and more efficiently by finding results in the technical documentation available to customers and technical support teams or by finding similar cases already treated. The result is an important gain in search time, as well as an increase of customers and technical support autonomy. Based on these technical requests, Airbus Helicopters technical support is also gathering the return of experience of the in-service behavior of the global fleet. Thanks to the Machine Learning technology, an automatic classification of technical requests is set up to determine if a request is relevant for return of experience or not. These AI technologies permit to reduce the low-added valued tasks - search for information, to allow Airbus Helicopters teams to have more time to focus on high-added valued tasks - technical analysis.

Published: June 2023

In this paper we introduce integrated VABS (iVABS) a tool to aid in the design of composite slender structures. iVABS can be used as an inverse tool to determine cross-section design given structural properties, such as torsional and bending stiffnesses, and inertial constraints (i.e., mass per unit length). In this work we explore using iVABS for designing the structural elements of a composite blade. We use a modified UH-60A blade; the updated outer mold line used in this study is a blade design presented by Allen et al. (ref. 1). In this effort we endeavor to develop a composite blade design that matches the torsional, chordwise and flap stiffnesses, blade mass per unit length, and shear center and center of gravity offsets properties of the UH-60A blade, while meeting strength constraints for the blade. In this initial effort we found that meeting the strength constraints and matching the target blade properties was challenging to do simultaneously with iVABS. Further work is needed to refine the optimization problem, chosen design variables, and cross-section templates to improve the final blade design. Regardless, this work demonstrates the power and flexibility of iVABS to quickly explore the design space. In the hands of an experienced design engineer iVABS could be a powerful tool to reduce design cycle times and develop innovative blade structural designs.
High-Fidelity Structured Mesh Models for As-Manufactured Composite
Authors:   Numerical Technology Company, Nikishkov Yuri ,   University of Texas at Arlington, Seon Guillaume , Makeev Andrew
Published: June 2023

High-resolution X-Ray computed tomography have demonstrated a unique ability to accurately detect and quantify critical subsurface irregularities, such as voids, waviness, and service damage in composites. While significant progress has been made in the respective areas of characterization and failure predictions, integrating 3D material characterization and non-destructive inspection of composites at the coupon scale into a comprehensive methodology applicable to failure prognosis of composite structures has yet to be developed. Such integration is especially important for the additively manufactured continuous fiber-reinforced thermoplastics that are often built with specific microstructural irregularities, such as voids, ply and fiber waviness, geometric errors, and variability of individual layers. The objective of this work is to provide a comprehensive description of novel modeling techniques used for the automated generation of structured mesh FE models for composite laminates that include as-designed and as-manufactured conditions while maintaining high-fidelity definition of model properties needed for the accurate predictions of structural performance.
Reliability Prediction with No Observed Field Failure but with Known Design Lives
Authors:   Sikorsky a Lockheed Martin Company, Pham Loan , Hewitt John
Published: June 2023

To minimize direct maintenance cost while also ensuring optimum system safety and availability, rotorcraft fleet management decision making must be based on accurate forecasts of component reliability and proper maintenance policy. However, component reliability predictions such as Mean Time to Failure (MTTF), hazard function, and reliability curve are typically performed based on MIL-HDBK-217 that is adjusted for field data once failures have been observed. MIL-HDBK-217 includes a series of empirically based hazard rate models with a fundamental assumption of exponential statistical distribution i.e., constant hazard rate. This assumption is not accurate for mechanical components that might have a non-constant hazard function. Furthermore, fleet management decision making is required during the development process before there is any field experience. This paradigm could change if component reliability predictions can be performed early when no field failures have occurred. Through this approach of performing a component reliability prediction with no field failures but with known design lives, rotorcraft reliability metrics can be more predictive thus better reliability prediction and maintenance policies can be determined early.

Published: June 2023

Spinal cord injury without radiographic abnormality (SCIWORA) is a rare post-traumatic myelopathy, more frequently seen in paediatric population and elderly. Clinical manifestation can range from transient isolated paraesthesia to quadriplegia. Due to its rarity in adults and the broad spectrum of neurological manifestations, SCIWORA actually represents a challenge for emergency physicians. Early diagnosis and timely intervention are crucial for the patient’s prognosis avoiding permanent neurological deficits. Magnetic resonance imaging (MRI) plays a pivotal role in the diagnosis, management and prognosis of SCIWORA, being the golden standard technique to identify spinal cord injuries. To highlight the importance of in-depth neurological examination and early diagnosis of SCIWORA, we describe the case of a 53-year-old woman who presented to our emergency department following a forward fall down the stairs with a minor head injury.
Emergency care accessibility for road accidents victims: a review
Authors: Rahvy Aisyah Putri , Gani Ascobat
Published: June 2023

Road traffic accident has become a public health concern. More than 80% injury-related deaths occurred in low-middle income countries (LMICs). Despite its importance, emergency care accessibility for road crash victims is still questionable. This study aims to review emergency care accessibility from approachability, acceptability, availability, affordability, and appropriateness dimensions for crash victims. This is a scoping review with literatures extracted from ScienceDirect, ProQuest, and Scopus. Articles analyzed using PCC (Problem/Population, Concept, Context) of scoping review. 1544 articles identified from databases of which 81 are relevant for full-text screening. The final 12 articles were eligible to be reviewed. Although emergency care is available in most areas, its existence was not well-known. Victims and helpers are treated unfairly in emergency care. Emergency care system also lacks clear coordination and it does not give appropriate treatment in timely manner. There was little evidence of how accessible emergency care to crash victims. Most studies only examined the availability of emergency care without comparing its actual utilization and other determinants impacting its accessibility. Future study should aim to assess approachability, acceptability, affordability, and appropriateness of emergency care. Strengthening emergency care from all dimensions is important to ensure its accessibility.
A narrative review on palliative care in the emergency department: dealing with the uncertainty of death
Authors: Porta Lorenzo , Mauri Eugenia
Published: June 2023

In the last decades emergency physicians have observed a steep increase in the emergency department (ED) admissions of palliative care patients who rely on the hospital for symptoms’ relief and management of acute exacerbations of their chronic disease. Previous studies have suggested that palliative care interventions in the ED could prevent unnecessary admissions and reduce both the length of hospitalization and costs. However, emergency medicine physicians might have limited specialistic education and resources to provide a correct management of palliative care patients and avoid futile interventions. Thus, we aim in this narrative review to provide the reader with an introduction on the principles that should guide the emergency physician in a correct approach to palliative care patients in the ED. We will explain how to deal with the intrinsic prognostic uncertainty of palliative care patients by implementing a correct ethical approach which encompasses the understanding of both appropriateness and futility of intervention; furthermore, we will present practical tools such as scores and trials.

Multiple sclerosis (MS) is the most prevalent immune-mediated inflammatory demyelinating central nervous system disorder, with a diverse set of clinical signs and symptoms. This study aimed to investigate the diagnostic values of the monocyte/lymphocyte ratio (MLR), red cell distribution width/lymphocyte ratio (RLR), and systemic immune-inflammation index (SII) in detecting multiple sclerosis attacks in patients with Relapsing-remitting MS (RRMS) presenting to the emergency department (ED). This retrospective observational study was conducted among patients with RRMS presenting to the ED of a third-level hospital. The laboratory parameters of 165 patients were compared during the attack and non-attack periods. The paired t-test statistic was used to compare means of inflammatory biomarker measurements between attack and non-attack groups. The neutrophil/lymphocyte ratio (NLR), MLR, RLR, and SII mean of the patients in the MS attack periods were higher than those in the non-attack period. The mean difference of NLR, MLR, RLR, and SII between both groups was 5.40±7.25, 0.37±0.43, 7.77±11.61, 1469.19±1978.88, respectively (p<0.001). In ROC analysis, NLR, RLR, MLR, and SII had excellent diagnostic power in detecting MS relapse (AUC: 0.87, 0.81, 0.86, and 0.87, respectively). According to our findings, SII, MLR, NLR, and RLR may be beneficial in confirming the diagnosis of attack in patients with RRMS.
The importance of concord between nations for scientific progress in cardiopulmonary resuscitation. A literature review

Published: June 2023

Conflict between nations harms, not only its direct victims, but often the next generations. History teaches us that concord and international cooperation favors the progress of science, especially medicine, while wars and violence provoked by different religious, ideological, political, and sociocultural contexts hinder scientific research, to the detriment of humanity. The objective of this article is to recall some notable figures in the history of cardiopulmonary resuscitation (CPR), focusing on the negative consequences of ideological persecution for the science of CPR.

Both specialists and trainees in emergency medicine are often unaware of the principles of good suturing. Hands-on training course was proposed to both members of the staff (group A) and trainees (group B) of the emergency department of our hospital. Familiarity with all aspects of the operation, pre-course 0%, postcourse 79% (group A) and 85.71% (group B) - p<0.000); clear economy of movement and maximum efficiency, pre-course 0%, post-course 73.8% (group A) and 89.80% (group B) - p<0.000; fluid moves with instruments and no awkwardness, pre-course 0%, post-course 73.8% (group A) and 89.80% (group B) - p<0.000; obviously planned course of operation with effortless flow from one move to the next, pre-course 0%, post-course 79% (group A) and 89,80% (group B) - p<0.000; strategically used assistants to the best advantage of all time, pre-course 0%, post-course 73,8% (group A) and 89,80% (group B) - p<0.000; improvement in dexterity, 79.5% of students post-course). The course was judged very useful by 94.8% of students. Attending suturing skill courses could be very useful for both trainees and specialists in emergency medicine.
Descriptive Epidemiology of Game-Related Youth Flag Football Injuries
Authors: Foss Kim Daneen Barber , Khoury Jane C. , Eisenmann Joey C. , Cappaert Thomas A.
Published: June 2023

Context

Flag football is promoted as a safer alternative to tackle football. This may be 1 reason why participation rates have risen by 39% over the past 3 years. Despite rising participation, epidemiologic research on sport-specific injuries and associated relative risk is lacking.

Objective

To prospectively document the epidemiology of injuries in youth flag football.

Design

Descriptive epidemiology study.

Setting

Regional and national youth flag football tournaments.

Patients or Other Participants

Athletes (N = 1939; 1744 boys and 195 girls), ages 6 to 12 years. An athletic trainer prospectively monitored the athletes for sport-related injury and exposures.

Main Outcome Measure(s)

Athlete risks of injury and injury rates were calculated overall and by sex. Injury characteristics were reported for the total population and by sex.

Results

Forty-seven injuries to unique individuals were recorded in 1939 athletes with a total of 9228 athlete-exposures (AEs). The overall risk of injury was 2.4% (95% CI = 1.79%, 3.21%), with an overall injury rate of 5.1 per 1000 AEs (95% CI = 3.75, 6.77). Of the 47 injuries, 36 occurred in boys (8365 AEs), and 11 occurred in girls (863 AEs). A higher risk in girls was evidenced by both the injury risk ratio (2.73; 95% CI = 1.41, 5.30) and injury rate ratio of 2.96 (95% CI = 1.51, 5.82). The most common injury sites were the head/face/neck (n = 15, 31.9%), followed by the ankle/foot (n = 9, 19.1%). The most frequent types of injury were contusion (55.3%), sprain/subluxation (14.9%), and general trauma (10.6%); 74.5% of all injuries resulted from direct impact.

Conclusions

Although the competition injury rate for youth flag football was lower than the values from studies reporting comparable tackle football data, the frequencies by body part, type, and mechanism were similar. Given that most injuries were related to some form of impact and predominantly contusions, adopting minimal protective equipment or padding may reduce the numbers of these injuries.
