ABSTRACT
El objetivo del presente trabajo es analizar el desempeño deportivo de la delegación chilena en los Juegos Panamericanos celebrados entre los años 1951 y 2023, haciendo uso de datos retrospectivos y proyectivos a través de series temporales de tiempo. Para esto se empleó un diseño cuantitativo, no experimental y longitudinal de tendencias y un método de suavización exponencial simple, que utiliza promedios históricos y que permite realizar una predicción o comportamiento futuro basado en una media ponderada de los valores actuales y de los pasados. A partir de los resultados obtenidos, fue posible concluir que, en las últimas décadas, la ubicación de Chile en el ranking de los Juegos Panamericanos se ha estabilizado en torno a un onceavo lugar, posición pronosticada para Santiago 2023. Manteniéndose condiciones similares, el desempeño deportivo general y específico no tendría un quiebre exponencial de la tendencia y los resultados no resultan favorables, específicamente en lo que respecta a la obtención de medallas de oro y la posición general de la delegación.
The objective of this paper is to analyze the sports performance of the Chilean delegation in the Pan American Games held between 1951 and 2023, using retrospective and projective data through time series. For this purpose, a quantitative, non-experimental and longitudinal design of trends and a simple exponential smoothing method was used, which uses historical averages and allows a prediction or future behavior based on a weighted average of current and past values. From the results obtained, it was possible to conclude that, in recent decades, Chile's position in the Pan American Games ranking has stabilized around eleventh place, a position predicted for Santiago 2023. Maintaining similar conditions, the general and specific sporting performance would not have an exponential break in the trend and the results are not favorable, specifically in terms of obtaining gold medals and the overall position of the delegation.

SUMMARY: In the sports field, sports are usually classified according to the predominance of the energy system used during the competition; sports like Crossfit and ultra-marathon could be totally opposite due to the needs of athletes to achieve good places. Due to the above, the objective was established to compare the dermatoglyphic profiles of CrossFit and Ultra-marathon athletes according to the predisposition of the energy systems, aerobic and anaerobic, used in the competitions. Cross-sectional descriptive study, where the dermatoglyphic profile of 21 athletes of national presence (10 crossfit and 11 ultra-marathon runners) was determined, through the Computerized Dermatoglyphic System, brand Salus Dermatoglifia, according to the Cummins and Midlo protocol, which consists of taking the fingerprints of the 10 fingers of the hands. The fingerprint designs of the human being (arch, loop and whorl) and the elements contained in them (nucleus and delta) were analyzed, differences were established through the Analysis of Variance test in the SPSS V.25 statistical package. The results show significant differences between the average scores of the line count of both disciplines (108 and 165), being higher in ultra-marathon runners, associated with greater aerobic resistance. Another significant and relevant finding was the presence of arch-type fingerprints only in CrossFit athletes associated, along with low line count, with strength and power. It is concluded that Crossfit and Ultra-marathon athletes have dissimilar natural physical characteristics, which is why they participate and excel in different sports where they have enhanced their natural physical abilities through training.
En el ámbito deportivo, los deportes suelen clasificarse según el predominio del sistema energético utilizado durante la competición; Deportes como el Crossfit y la ultramaratón podrían ser totalmente opuestos debido a las necesidades de los deportistas de conseguir buenos lugares. Debido a lo anterior, se estableció como objetivo comparar los perfiles dermatoglíficos de atletas de CrossFit y Ultramaratón según la predisposición de los sistemas energéticos, aeróbico y anaeróbico, utilizados en las competencias. Estudio descriptivo transversal, donde se determinó el perfil dermatoglífico de 21 deportistas de presencia nacional (10 crossfit y 11 ultramaratonistas), a través del Sistema Dermatoglífico Computarizado, marca Salus Dermatoglifia, según el protocolo Cummins y Midlo, el cual consta de tomando las huellas dactilares de los 10 dedos de las manos. Se analizaron los diseños dactilares del ser humano (arco, asa y verticilo) y los elementos contenidos en ellos (núcleo y delta), se establecieron diferencias mediante la prueba de Análisis de Varianza en el paquete estadístico SPSS V.25. Los resultados muestran diferencias significativas entre las puntuaciones medias del recuento de líneas de ambas disciplinas (108 y 165), siendo superiores en los corredores de ultramaratón, asociado a una mayor resistencia aeróbica. Otro hallazgo significativo y relevante fue la presencia de huellas dactilares tipo arco sólo en atletas de CrossFit asociadas, junto con un bajo número de líneas, con fuerza y potencia. Se concluye que los atletas de Crossfit y Ultramaratón tienen características físicas naturales disímiles, por lo que participan y destacan en diferentes deportes donde han potenciado sus capacidades físicas naturales a través del entrenamiento.

SUMMARY: World Taekwondo (WT) as an Olympic sport gained much more attention than before, and there is a growing need for precise and specific profiles of successful taekwondo competitors. Aim of this investigation was to determine body composition, somatotype, and selected anthropometric parameters/indexes of elite taekwondo champions and medal winners on the most demanding taekwondo tournaments in the World. The sample for this research consisted of n=16 (n=4 male; n=12 female) elite taekwondo champions, n=8 juniors and n=8 seniors, who were European (n=13), and World (n=3) champions of European descent. Data was collected longitudinally for seven years since 2015. Obtained results revealed specific (absolute) phenotype of taekwondo champions, following: PI (11.50 female; 11.85 male), HWR (43.96 female; 44.47 male) and BMI (19.96 female; 22.04 male). Further analysis shows that champions have greater values of body height, and have slightly greater ectomorphy and mesomorphy values in regard to other elite competitors. Presented research is the first publication of referent values for the general anthropometric dataset, and such results represent the anthropometric variability of European WT champions.

ABSTRACT This study aimed to review the projects financed between 2014 and 2022 under the ERASMUS+ programme of the European Commission to examine the past and present implementation of the dual career (DC) of elite sportspersons and to highlight potential gaps to guide future project proposals. Findings showed a relevant focus of the financed projects on the micro and multi-dimensional aspects of DC of athletes as the main target group, implementing training courses/programmes in different settings, and partnerships mostly composed by educational institutions and NGOs. In the future, sports bodies should engage more in partnerships, whereas DC of employee-sportspersons as athletes and sports staff should be implemented, with a strong focus on the project's long-term impact and sustainability.
RESUMO Este estudo teve como objetivo rever os projetos financiados entre 2014 e 2022 no âmbito do programa ERASMUS+ da Comissão Europeia de forma a melhor perceber a implementação dos mesmos no âmbito da dupla carreira (DC) de atletas de elite e destacar eventuais lacunas para orientar futuras propostas de projetos. Os resultados encontrados apontam para uma maior predominância dos aspectos micro e multidimensionais da DC, sendo os atletas o principal grupo-alvo, propondo-se a implementação de cursos/programas de formação em diferentes contextos, assim como parcerias maioritariamente compostas por instituições de ensino e ONG's. Surge ainda recorrentemente a nota de, no futuro, os organismos desportivos se envolverem mais em parcerias, e a extensão da DC a outros agentes como os treinadores e árbitros, assim como o alargamento ao enquadramento dado pelo mocal de trabalho (mercado de trabalho), sempre com a tónica colocada no impacto e na sustentabilidade do projeto a longo prazo.
RESUMEN Este estudio tuvo como objetivo revisar los proyectos financiados entre los años 2014 y 2022 dentro el programa ERASMUS+ de la Comisión Europea, para analizar el presente y el pasado de la implementación de la carrera dual (DC) de deportistas de élite, resaltando posibles errores que permitan guiar futuras propuestas de proyectos. Los resultados mostraron un importante foco de los proyectos en aspectos micro y multidimensionales de la CD de los atletas como principal punto a destacar, implementando cursos/programas de entrenamiento en diferentes entornos y colaboraciones compuestas principalmente por instituciones educativas y ONGs. En el futuro, los organismos deportivos deberían participar más con asociaciones, así como que se debería implementar la DC de los empleados-deportistas como atletas y como personal deportivo, con un fuerte enfoque en el impacto y la sostenibilidad del proyecto a largo plazo.

ABSTRACT
ABSTRACT Introduction The focus of attention in high-performance athlete injuries tends to be on physical recovery, neglecting psychological factors and their practical social impacts on the rehabilitation of the injured athlete. In this phase, giving attention to the importance of athletes' thoughts, emotions, and motivation can speed up the biopsychosocial rehabilitation process. Objective To analyze the characteristics involved in the major sports injuries of high-level athletes to provide a reference for athletes and coaches during recovery. Methods This article analyzes through bibliographic research the characteristics of the major sports injuries in high-level athletes, including physiological, psychological, and social factors. Results The physical impact of injuries requires patience and persistence for recovery, including additional muscle strengthening to compensate for the loss of residual joint proprioception, ensuring performance recovery. Mental factors such as insecurity when returning from games, reduced self-confidence, and fear of hurting the team must be worked through in parallel in multi-professional care and during long recovery periods. Conclusion Sports injuries can occur in athletes of all levels. For elite athletes, the impact of injuries, especially severe ones that need to interrupt training or even surgery, will lead to forced suspension of training or competition, preventing the improvement of sports performance, decreasing the quality of the sports career, and may even lead to physical or psychological disability in severe cases. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
RESUMO Introdução O foco da atenção nas lesões dos atletas de alto desempenho tende a ser a recuperação física, negligenciando os fatores psicológicos e seus impactos sociais práticos na reabilitação do atleta lesionado. Atentar-se a importância dos pensamentos, emoções e motivação dos atletas nessa fase pode agilizar o processo de reabilitação biopsicosical. Objetivo Analisar as características envolvidas nas principais lesões esportivas dos atletas de alto nível, a fim de fornecer referência para atletas e treinadores durante a recuperação. Métodos Este artigo analisa através de pesquisa bibliográfica as características das principais lesões esportivas dos atletas de alto nível, incluindo fatores fisiológicos, psicológicos e sociais. Resultados O impacto físico das lesões requer paciência e persistência para recuperação, incluindo o fortalecimento muscular adicional visando compensar a perda da propriocepção articular residual, garantindo a recuperação do desempenho. Fatores mentais como insegurança na volta dos jogos, redução de autoconfiança e medo de prejudicar o time devem ser trabalhados paralelamente num atendimento multiprofissional e deve-se compensar os aspectos de socialização nas recuperações de longo prazo. Conclusão As lesões esportivas podem ocorrer em atletas de todos os níveis. Para os atletas de elite, o impacto das lesões, especialmente as graves que precisam interromper o treinamento ou mesmo a cirurgia, levará à suspensão forçada do treinamento ou da competição, impedindo a melhoria do desempenho esportivo, diminuindo a qualidade da carreira esportiva e podendo até mesmo levar à incapacidade física ou psicológica em casos graves. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.
RESUMEN Introducción El foco de atención en las lesiones de los atletas de alto rendimiento tiende a centrarse en la recuperación física, descuidando los factores psicológicos y sus impactos sociales prácticos en la rehabilitación del atleta lesionado. Prestar atención a la importancia de los pensamientos, las emociones y la motivación de los deportistas en esta fase puede acelerar el proceso de rehabilitación biopsicológica. Objetivo Analizar las características implicadas en las principales lesiones deportivas de los atletas de alto nivel, con el fin de proporcionar una referencia para los atletas y los entrenadores durante la recuperación. Métodos Este artículo analiza a través de la investigación bibliográfica las características de las principales lesiones deportivas de los atletas de alto nivel, incluyendo factores fisiológicos, psicológicos y sociales. Resultados El impacto físico de las lesiones requiere paciencia y persistencia para la recuperación, incluido el fortalecimiento muscular adicional destinado a compensar la pérdida de la propiocepción articular residual, asegurando la recuperación del rendimiento. Los factores mentales, como la inseguridad para volver a los juegos, la disminución de la confianza en sí mismo y el miedo a dañar al equipo, deben trabajarse en paralelo en una atención multiprofesional, y los aspectos de socialización deben compensarse en las recuperaciones a largo plazo. Conclusión Las lesiones deportivas pueden producirse en atletas de todos los niveles. En el caso de los deportistas de élite, el impacto de las lesiones, sobre todo de las más graves que obligan a interrumpir el entrenamiento o incluso a operar, conlleva la suspensión forzosa de los entrenamientos o de la competición, impidiendo la mejora del rendimiento deportivo, disminuyendo la calidad de la carrera deportiva y pudiendo llegar incluso a la incapacidad física o psicológica en los casos graves. Nivel de evidencia II; Estudios terapéuticos - investigación de los resultados del tratamiento.

BACKGROUND Elite controllers (EC) are human immunodeficiency virus (HIV)-positive individuals who can maintain low viral loads for extended periods without antiretroviral therapy due to multifactorial and individual characteristics. Most have a small HIV-1 reservoir composed of identical proviral sequences maintained by clonal expansion of infected CD4+ T cells. However, some have a more diverse peripheral blood mononuclear cell (PBMC)-associated HIV-1 reservoir with unique sequences. OBJECTIVES To understand the turnover dynamics of the PBMC-associated viral quasispecies in ECs with relatively diverse circulating proviral reservoirs. METHODS We performed single genome amplification of the env gene at three time points during six years in two EC with high intra-host HIV DNA diversity. FINDINGS Both EC displayed quite diverse PBMCs-associated viral quasispecies (mean env diversity = 1.9-4.1%) across all time-points comprising both identical proviruses that are probably clonally expanded and unique proviruses with evidence of ongoing evolution. HIV-1 env glycosylation pattern suggests that ancestral and evolving proviruses may display different phenotypes of resistance to broadly neutralising antibodies consistent with persistent immune pressure. Evolving viruses may progressively replace the ancestral ones or may remain as minor variants in the circulating proviral population. MAIN CONCLUSIONS These findings support that the high intra-host HIV-1 diversity of some EC resulted from long-term persistence of archival proviruses combined with the continuous reservoir's reseeding and low, but measurable, viral evolution despite undetectable viremia.
ABSTRACT
Abstract Funding is one of the most controversial areas when analyzing the likelihood of performance in elite sports. In order to establish the level of funding available in this area, it was necessary to establish certain conceptual margins with respect to elite sport and to determine the different sectors of sport that fit the proposed conceptual definition. Using a non-experimental descriptive method, based on empirical research in sports sciences and a meta-analysis strategy secondary information available on various websites of public services of Chile, together with yearbooks and information requested from entities linked to elite sport, Secondary information was collected that allowed knowing the different lines of funding from each of the factors and sub-factors of pillar 1 of the SPLISS model, proposed by De Bosscher et al. (2006) for the achievement of elite sport achievement that was part of the study. In conclusion, it can be established that a permanent increase in funding does not guarantee performance in elite sports.
Resumo O financiamento é uma das áreas mais controversas ao analisar a probabilidade de desempenho no esporte de elite. Para estabelecer o nível de financiamento disponível nesta área, foi necessário estabelecer certas margens conceituais a respeito do esporte de elite e determinar os diferentes setores do esporte que se encaixam na definição conceitual proposta. Utilizou-se um método descritivo não experimental, baseado em pesquisa empírica em ciências do esporte e uma estratégia de meta-análise, informações secundárias disponíveis em vários sites de serviços públicos do Estado do Chile, juntamente com anuários e informações solicitadas de entidades ligadas ao esporte de elite. Foram coletadas informações secundárias que permitiram conhecer as diferentes linhas de financiamento de cada um dos fatores e subfatores do pilar 1 do modelo SPLISS, proposto por De Bosscher et al. (2006) para a ocorrência de realizações esportivas de elite que fizeram parte do estudo. Em conclusão, pode-se estabelecer que um aumento permanente no financiamento não garante o desempenho no esporte de elite.

Se utilizó un método descriptivo no experimental basado en la investigación empírica en ciencias del deporte. Se empleó una estrategia de meta-análisis y se obtuvo información secundaria disponible en los sitios web de servicios públicos chilenos, además de anuarios e información solicitada a entidades vinculadas al deporte de élite. Esta información secundaria permitió conocer las diferentes líneas de financiamiento de cada uno de los factores y subfactores del pilar 1 del modelo SPLISS, propuesto por De Bosscher et al. (2006) para la consecución del deporte de élite que formaron parte del estudio. En conclusión, se puede establecer que un aumento permanente en la financiación no garantiza el rendimiento en el deporte de elite.
ABSTRACT
SUMMARY: Anthropometry is essential to understand the predisposition of an athlete to practice a specific sporting activity, to assess their fitness, and in association with functional parameters, to identify any correlations between their anthropometric profile and their sport performance. Here, we present the anthropometric profiles of athletes of the Italian national teams, who represented Italy in the 2019-2020 competitive season in the following sports: artistic (n=4) and rhythmic (n=12) gymnastics; distance swimming (speciality: 100 m freestyle) (n=14); synchronized swimming (n=10); and basketball (n=6). We also consider a group of sedentary women (n=22) for comparisons. The following anthropometric measurements were taken for each woman: stature; anterior trunk height (i.e., suprasternal- symphysion distance); chest circumference passing through the mesosternal point; biacromial diameter (i.e., akromion-akromion distance); wrist circumference; abdominal circumference passing through the omphalion and the lumbale; hip circumference; height of lower limb (i.e., epitrochanter-planta distance). Height was a selective factor in both basketball, which requires tall athletes, and artistic gymnastics, where in contrast, well-muscled athletes of small stature are required. In aquatic sports, the constitutional habitus is characterized by good development of the upper body compared to the lower limbs. The selection of elite athletes takes place primarily through anthropometric analyses, although other functional and psychological factors also influence their sports performance.
RESUMEN: La evaluación antropométrica de un atleta es fundamental para conocer su predisposición en la práctica de un determinado deporte, evaluar su estado de forma y, junto a los parámetros funcionales, identificar posibles relaciones entre el perfil antropométrico y el rendimiento. A continuación, presentamos el perfil antropométrico de las atletas de los Equipos Nacionales que representaron a Italia en la temporada 2019-2020 en las siguientes disciplinas deportivas: gimnasia rítmica (n=12), gimnasia artística (n=4), nado sincronizado (n=10), natación (especialidad: 100 m estilo libre) (n=14), baloncesto (n=6). A cada atleta le fueron efectuadas las siguientes mediciones: altura, altura anterior del torso (distancia supraesternal-symphysion), circunferencia torácica en el punto mesosternal, diámetro biacromial (distancia acromion-acromion), circunferencia de la muñeca, circunferencia abdominal a nivel umbilical, circunferencia pélvica, altura del miembro inferior (distancia epitrocantérea-planta). La altura es el factor selectivo en el baloncesto, que exige atletas altas, así como en la gimnasia artística que, al contrario, requiere atletas no muy altas y con una buena musculatura. En los deportes acuáticos, el rasgo característico es un buen desarrollo de la parte superior del cuerpo respecto a la parte inferior. La selección de los atletas de elite se realiza en primer lugar a través de estudios antropométricos, aunque el rendimiento depende también de otros factores funcionales y psicológicos.

ABSTRACT
Introduction: L'hygiène orale représente l'ensemble des mesures prises pour garder la cavitéÌ orale propre et saine en maintenant les surfaces dentaires dépourvues de plaque et de tartre. L'objectif de cette étude était d'évaluer l'hygiène buccodentaire des Unités d'Élites des forces de défense et de sécurité du Mali. Méthodologie : Il s'agissait d'une étude transversale descriptive qui s'est déroulée du 01 Septembre 2020 au 30 Aout 2021 dans le service d'Odontologie de l'Infirmerie Hôpital de Bamako (IHB). La population d'étude était constituée de militaires en service dans les différentes Unités d'Élites des corps d'Armée du Mali venus en consultation dans le service d'Odontologie et par d'autres Unités dans leur Quartier Général (QG) compte tenu de leur confidentialité. Résultats : Dans cette étude, la tranche d'âge 30 39 ans était la plus représentée avec 49,2%. Les sous-officiers étaient les plus représentés avec 55,0%. Parmi les Unités d'Élites, la CIR représentait 34,8%. Pour le brossage des dents, 85,9% se brossaient les dents. Par rapport au nombre de brossage par jour, 54,7% se brossaient les dents 1 fois par jour. Tandis que 48,1% se brossaient les dents avec une brosse de type Medium. Pour le saignement après le brossage, 42,6% avaient un saignement après le brossage. Conclusion: Cette étude a montré que les militaires avaient une connaissance sur l'hygiène buccodentaire car ils se brossaient majoritairement 1 à 2 fois par jour. Toutefois, beaucoup de militaires présentaient un saignement après brossage. Devant cette situation, une nouvelle orientation de la politique de santeÌ bucco-dentaire basée sur l'odontologie préventive s'impose afin d'améliorer la santeÌ et la qualitéÌ de vie de ces militaires
Introduction: Oral hygiene represents all the measures taken to keep the oral cavity clean and healthy by keeping the dental surfaces free of plaque and tartar. The objective of this study was to evaluate the oral hygiene of elite units of the defense and security forces of Mali. Methodology: This was a descriptive cross-sectional study that took place from September 01, 2020, to August 30, 2021, in the odontology department of Bamako Military Hospital. The study population involved soldiers of various Elite Units of the Armed Forces of Mali who came for consultation in the odontology service. Results: In this study, the 30-39 age group was the most represented with 49.2%. NCOs were the most represented with 55.0%. Among Elite Units, the CIR accounted for 34.8%. For tooth brushing, 85.9% brushed their teeth. Regarding the number of brushings per day, 54.7% brushed their teeth once a day. While 48.1% brushed their teeth with a medium brush. For bleeding after brushing, 42.6% had bleeding after brushing. Conclusion: This study showed that the military had knowledge of oral hygiene because they brushed mostly 1 to 2 times a day. However, many soldiers had bleeding after brushing. Faced with this situation, a new orientation of the oral health policy based on preventive odontology is necessary in order to improve the health and quality of life of these soldiers

Las infecciones de las vías respiratorios altas (IVRA), son debilitantes para el potencial deportivo de los atletas de élite. El ejercicio físico activa múltiples vías moleculares y bioquímicas relacionadas con el sistema inmune, sensibles a influencias nutricionales. Sobre este contexto, la inmunonutrición está adquiriendo una nueva dirección orientada a conseguir el equilibrio inmunológico, contraponiéndose con algunas de las teorías que han sentado las bases de la inmunología del ejercicio durante las últimas décadas. Objetivo. Investigar los aspectos nutricionales que puedan mejorar la respuesta inmunológica en deportistas de elite. Estudiar los posibles beneficios del equilibrio inmunológico para mejorar el rendimiento, analizar los factores nutricionales que contribuyan al equilibrio de la respuesta inmunológica y extrapolar la evidencia actual en recomendaciones prácticas de alimentación/suplementación para mejorar la homeostasis de la respuesta inmunológica en atletas de élite, teniendo en cuenta las limitaciones existentes.Resultados. La evidencia científica apunta que se puede potenciar el equilibrio inmunológico y la respuesta inmune a través de la modificación de factores nutricionales. Dentro de los cuales, la vitamina D, los probióticos, la vitamina C y el cinc son los que cuentan con mayor evidencia. Conclusión. Los avances científicos resultan prometedores y de interés para los atletas de élite, debido a que pueden disminuir la incidencia de IVRA, mejorando el éxito deportivo de los mismos. Se requieren más estudios para su validación y aplicación(AU)
Upper respiratory tract infections (URTI) are debilitating for the athletic potential of elite athletes. Physical exercise in elite athletes activates multiple molecular and biochemical pathways related to the immune system, which, at the same time, are sensitive to nutritional influences. Based on this context, immunonutrition is taking a new direction aimed at achieving the immunological balance. Objective. To investigate the nutritional aspects that can improve the immune response in elite athletes. To study the potential benefits of immune balance to improve performance, to analyse nutritional factors that contribute to the balance of the immune response and to extrapolate current evidence into practical dietary/supplementation recommendations to improve the homeostasis of the immune response in elite athletes, considering existing limitations. Results. Scientific evidence suggests that immune balance and immune response can be enhanced through the modification of nutritional factors. Among which, vitamin D, probiotics, vitamin C and zinc are the micronutrients with most evidence. Conclusion. Scientific advances in this field are promising and of great interest to elite athletes since it could decrease the incidence of URTI and, as a consequence, it could improve their sporting success. However, more studies are still required for its validation and application(AU)

The interaction of HIV-1, human leukocyte antigen (HLA), and elite controllers (EC) compose a still intricate triad. Elite controllers maintain a very low viral load and a normal CD4 count, even without antiretrovirals. There is a lot of diversity in HIV subtypes and HLA alleles. The most common subtype in each country varies depending on its localization and epidemiological history. As we know EC appears to maintain an effective CD8 response against HIV. In this phenomenon, some alleles of HLAs are associated with a slow progression of HIV infection, others with a rapid progression. This relationship also depends on the virus subtype. Epitopes of Gag protein-restricted by HLA-B*57 generated a considerable immune response in EC. However, some mutations allow HIV to escape the CD8 response, while others do not. HLA protective alleles, like HLA-B*27, HLA-B*57 and HLA-B*58:01, that are common in Caucasians infected with HIV-1 Clade B, do not show the same protection in sub-Saharan Africans infected by HIV-1 Clade C. Endogenous pathway of antigen processing and presentation is used to present intracellular synthesized cellular peptides as well as viral protein fragments via the MHC class I molecule to the cytotoxic T-lymphocytes (CTLs). Some epitopes are immunodominant, which means that they drive the immune reaction to some virus. Mutation on an anchor residue of epitope necessary for binding on MHC class I is used by HIV to escape the immune system. Mutations inside or flanking an epitope may lead to T cell lack of recognition and CTL escape. Studying how immunodominance at epitopes drives the EC in a geographically dependent way with genetics and immunological elements orchestrating it may help future research on vaccines or immunotherapy for HIV. 2021 Sociedade Brasileira de Infectologia.

SUMMARY: Success in artistic gymnastics certainly depends on the morphological characteristics of the athletes, some of which are basic body height and weight. The aim of this study is to determine whether there is a statistically significant difference in body height and weight between the male and female participants on the Olympic Games from 1996 to 2016. The following variables were chosen: body weight (kg), body height (cm). The results did show significant differences between women's artistic gymnastics in body weight and height over a 20-year period. In men's artistic gymnastics we didn't find the difference. This research is important in setting comparative parameters in the selection process and sport specialization regarding morphological characteristics according to different events of gymnasts at the elite level.
RESUMEN: El éxito en la gimnasia artística depende de las características morfológicas de los atletas, algunas de las cuales son la altura y el peso del cuerpo. El objetivo de este estudio fue determinar si existe una diferencia estadísticamente significativa entre la altura y el peso corporal en los participantes masculinos y femeninos en los Juegos Olímpicos de 1996 a 2016. Se eligieron las siguientes variables: peso corporal (kg), altura corporal (cm). Los resultados mostraron diferencias significativas entre la gimnasia artística femenina en el peso corporal y la altura durante un período de 20 años. En la gimnasia artística masculina no se observó diferencia. Esta investigación es importante para establecer parámetros comparativos en el proceso de selección y la especialización deportiva con respecto a las características morfológicas, de acuerdo a los eventos en que participan gimnastas de nivel de élite.

ABSTRACT
O objetivo deste estudo foi analisar as práticas dos jovens atletas de elite nos Jogos Olímpicos da Juventude diante das atividades culturais e educacionais a partir da observação direta e dos registros iconográficos atinentes à edição de Buenos Aires, cuja análise apoiou-se na teoria do cotidiano. Constata-se que a Vila Olímpica da Juventude é um ambiente deveras intercultural, cujo cotidiano é capaz de ensejar uma pluralidade de práticas tanto no plano estratégico, a partir da sua organização estrutural e da sua programação de atividades culturais e educacionais, quanto no plano tático, a partir dos usos e apropriações diferenciados dos jovens atletas, mobilizando táticas de desvio ou resistência e táticas de bricolagem. Conclui-se que os jovens atletas produziram sentidos que transcendiam as questões culturais e educacionais, associando-se, sobretudo, ao seu crescimento profissional enquanto atleta de elite.
The objective of this study was to analyze the practices of young high performance athletes in the Youth Olympic Games in the face of cultural and educational activities based on direct observation and iconographic records related to the Buenos Aires edition, whose analysis was based on the theory of daily life. It seems that the Youth Olympic Village is a truly intercultural environment, whose daily life is capable of giving rise to a plurality of practices both at a strategic level, from its structural organization and from its program of cultural and educational activities, and at a tactical level, based on the different uses and appropriations of young athletes, using diversion or resistance tactics and diy tactics. It is concluded that young athletes produced meanings that transcended cultural and educational issues, and were associated, mainly, with their professional growth as high performance athletes.
El objetivo de este estudio fue analizar las prácticas de los jóvenes atletas de alto rendimiento en los Juegos Olímpicos de la Juventud frente a actividades culturales y educativas basadas en la observación directa y los registros iconográficos relacionados con la edición de Buenos Aires, cuyo análisis se basó en la teoría de la vida cotidiana. Parece que la Villa Olímpica de la Juventud es un entorno verdaderamente intercultural, cuya vida diaria es capaz de dar lugar a una pluralidad de prácticas tanto a nivel estratégico, desde su organización estructural y su programa de actividades culturales y educativas, como a nivel táctico, basado en los diferentes usos y apropiaciones de los atletas jóvenes, utilizando tácticas de desviación o resistencia y tácticas de bricolaje. Se concluye que los atletas jóvenes produjeron significados que trascendieron cuestiones culturales y educativas, y se asociaron, mayormente, con su crecimiento profesional como atletas de alto rendimiento.
