Catamaran SI Joint Fusion System(R) MAINSAILTM Study: a prospective, single-arm, multi-center, post-market study of six-month clinical outcomes and twelve-month radiographic findings.

BACKGROUND: Minimally invasive surgical techniques for sacroiliac joint (SIJ) fixation have the potential to reduce risk and improve patient outcomes, but evidence remains limited. This interim analysis presents initial findings from an ongoing prospective study evaluating the safety and efficacy of the Catamaran System. METHODS: The primary endpoint of success at 6 months was defined as a ≥20 mm improvement in SIJ pain (Visual Analog Scale, VAS), no neurologic worsening, absence of device-related serious adverse events (SAEs), and no surgical reintervention. Secondary endpoints included 6 month evaluation of the Oswestry Disability Index (ODI), patient satisfaction, and 12 month radiographic CT fusion, performed by an indpendent radiologist. RESULTS: Thirty-three consecutive patients (mean age: 58.9 years; %-females: 76%; Body Mass Index: 30.5) were treated across six U.S. clinical sites. At the primary endpoint of 6 months, 80% of patients met the criteria for success, with no device-related SAEs and no surgical reintervention reported. VASSIJ-Pain significantly decreased from preoperative levels (mean: 80.9 mm) to 6 months postoperatively (31.1 mm; p < 0.001). Mean ODI scores also showed a significant improvement from preoperative values (51.9%) to 6 months postoperatively (29.6%, p < 0.01). Patients reported high satisfaction rates throughout all follow-ups, with 93.3% of patients being satisfied at 6 months. CONCLUSION: In patients diagnosed with chronic SIJ pain, minimally invasive inferior-posterior delivery of the Catamaran implant was safe and effective in relieving pain and reducing disability.

Elevated Serum Levels of YKL-40, YKL-39, and SI-CLP in Patients with Treatment Failure to DMARDs in Patients with Rheumatoid Arthritis.

Around 30-60% of patients with rheumatoid arthritis (RA) present treatment failure to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). Chitinase-like proteins (CLPs) (YKL-40, YKL-39, SI-CLP) might play a role, as they are associated with the inflammatory process. This study aimed to evaluate CLP utility as a biomarker in the treatment failure of csDMARDs. A case-control study included 175 RA patients classified into two groups based on therapeutic response according to DAS28-ESR: responders (DAS28 < 3.2); non-responders (DAS28 ≥ 3.2). CLP serum levels were determined by ELISA. Multivariable logistic regression and receiver operating characteristic (ROC) curves were used to evaluate CLPs' utility as biomarkers of treatment failure. Non-responders presented higher levels of YKL-40, YKL-39, and SI-CLP compared with responders (all: p < 0.001). YKL-40 correlated positively with YKL-39 (rho = 0.39, p < 0.001) and SI-CLP (rho = 0.23, p = 0.011) and YKL-39 with SI-CLP (rho = 0.34, p < 0.001). The addition of CLPs to the regression models improves diagnostic accuracy (AUC 0.918) compared to models including only clinical classical variables (AUC 0.806) p < 0.001. Non-responders were positive for all CLPs in 35.86%. Conclusions: CLPs could be considered as a useful biomarker to assess treatment failure, due to their association with clinical variables and improvement to the performance of regression models.

Microstructural and Electrochemical Study: Pitting Corrosion Mechanism on A390 Al-Si Alloy and Ce-Mo Treatment as a Better Corrosion Protection.

Sulfuric acid anodizing assisted by a hydrothermal sealing with inhibitors [Ce3+-Mo6+] was used to prevent pitting corrosion on spray-deposited hypereutectic Al-Si alloy (A390). An investigation concerning the evaluation of pitting corrosion resistance on the anodic oxide thin film with ions incorporated was carried out in NaCl solution using electrochemical measurements (i.e., potentiodynamic polarization and electrochemical impedance spectroscopy, EIS). The influence of Si phase morphology and size on the growth mechanism of an anodic oxide film was characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results were then compared with those for its equivalent IM390 alloy (Al-17Si-4.5Cu-0.6Mg) produced through a conventional process ingot metallurgy, IM. The electrochemical findings indicate that sulfuric acid anodizing followed by a simple hot water sealing treatment was ineffective. In this manner, an intense attack was localized by pitting corrosion that occurred on the anodic oxide film in less than three days, as denoted by characteristic changes in the EIS spectra at the lowest frequencies. Improved results were achieved for Ce-Mo surface modification, which can provide better corrosion resistance on the aluminum alloys because no signs of pits were observed during the corrosion testing.

Uma abordagem integradora da construção biológica e psicossocial do self e da identidade / An integrative approach to the biological and psychosocial construction of the self and identity

RESUMO Self (si mesmo) e identidade são constructos psicossociais que têm sido estudados sob diferentes perspectivas teóricas e metodológicas nos campos da neurologia e da psicologia, sem, no entanto, que sejam evidenciadas as continuidades e convergências que possibilitam uma visão integradora de sua construção e funcionamento. Apesar de muitas vezes esses conceitos serem empregados como sinônimos, diversos estudos têm delimitado suas distinções e definido a identidade como uma configuração madura e mais elaborada do self, que emerge no início da adolescência. O presente estudo, de enfoque teórico, tem como objetivo apresentar uma abordagem integradora dos processos biológicos e psicossociais de construção do self e da identidade. Para tanto, inicia conceituando self e traçando um percurso que explora os componentes biológico, cognitivo-afetivo, sociocultural e moral que interatuam na construção do self e da identidade. Diferentes perspectivas tributárias da epistemologia piagetiana e da teoria da identidade de Erik Erikson (status da identidade e identidade narrativa) são postas em diálogo, evidenciando suas convergências e complementariedades, do que se desdobra uma visão integradora dos processos de construção da identidade.

RESUMEN Self (si mismo) e identidad son constructos psicosociales que han sido estudiados bajo diferentes perspectivas teóricas y metodológicas en los campos de la neurología y la psicología cognitiva, sin destacar, sin embargo, las continuidades y convergencias que permiten una visión integradora de su construcción y funcionamiento. Aunque estos conceptos sean usados a menudo como sinónimos, varios estudios han delimitado sus distinciones y definido la identidad como una configuración madura y más elaborada del yo, que surge en el comienzo de la adolescencia. El presente estudio, de enfoque teórico, tiene como objetivo enseñar un abordaje integrativo de los procesos biológicos y psicosociales de construcción del self y de la identidad. Con este fin, comienza por conceptualizar el yo y trazar un camino que explora los componentes biológico-filogenético, cognitivo-afectivo, sociocultural y moral que interactúan en la construcción del self y la identidad. Diferentes perspectivas tributarias de la epistemología de Piaget y de la teoría de la identidad de Erik Erikson (status de identidad e identidad narrativa) se ponen en diálogo, mostrando sus convergencias y complementariedades, a partir de las cuales se desarrolla una visión integradora de los procesos de construcción de la identidad.

ABSTRACT Self and identity are psychosocial constructs studied under different theoretical and methodological perspectives in the neurology and psychology fields without highlighting the continuities and convergences that enable an integrative view of their construction and functioning. Although these concepts are often used interchangeably, several studies have delimited their distinctions and defined identity as a mature and more elaborate configuration of the self, which emerges in early adolescence. With a theoretical focus, the present study aims to present an integrative approach to the biological and psychosocial processes of self and identity construction. To do so, it begins by conceptualizing the self and tracing a path that explores the biological, cognitive-affective, sociocultural and moral components that interact with self and identity construction. Different perspectives based on Piagetian epistemology and Erik Erikson's theory of identity (status and narrative identity) are put into dialogue, highlighting their convergences and complementarities, resulting in an integrative view of identity construction processes.

Resumo: A fim de responder à distinta questão que Foucault endereça à psicanálise em seu curso de 1982 - seria ela correspondente às exigências do cuidado de si ( epiméleia heautoû )? -, procedemos por uma aproximação teórica entre as estruturas de concepção do sujeito expostas em seu discurso, A hermenêutica do sujeito , e no discurso de Lacan, A instância da letra no inconsciente ou a razão desde Freud . O propósito do manuscrito visa tanto continuar com uma problematização inacabada por parte do filósofo francês quanto fazer ressoar na psicanálise uma obra que ainda não conta com grande recepção no meio.

Abstract: To answer the distinct question that Foucault addresses to psychoanalysis in his 1982 course - would it correspond to the demands of the care of the self ( epiméleia heautoû )? -, we proceed by a logical approximation between the structures of the subject's conception exposed in his speech, in The Hermeneutics of the Subject , and in the discourse of Lacan, in The Instance of the Letter in the Unconscious or Reason Since Freud . The purpose of the manuscript aims to continue with an unfinished problematization on the part of the French philosopher and to resonate in psychoanalysis a work that still does not have a great reception in the medium.

Résumé : Pour répondre à la question distincte que Foucault adresse à la psychanalyse dans son cours de 1982 - correspondrait-elle aux exigences du souci de soi ( epiméleia heautoû )? -, nous procédons par une approximation logique entre les structures de la conception du sujet exposées dans son discours, dans L'herméneutique du sujet , et dans le discours de Lacan, dans L'instance de la lettre dans l'inconscient ou la raison depuis Freud . Le but du manuscrit vise à la fois à poursuivre une problématisation inachevée de la part du philosophe Français et à faire résonner en psychanalyse une œuvre qui n'a toujours pas un grand accueil dans le médium.

Resumen: Para responder a la pregunta que Foucault dirige al psicoanálisis en su curso de 1982 -¿correspondería a las exigencias del cuidado de sí mismo ( epiméleia heautoû )?-, procedemos con una aproximación teórica entre las estructuras de la concepción del sujeto que se exponen en su discurso La hermenéutica del sujeto y en el de Lacan, en La instancia de la letra en el inconsciente o la razón desde Freud . El propósito de este trabajo es seguir con la problematización inconclusa por parte del filósofo francés y resonar en el psicoanálisis una obra que todavía no tiene una gran acogida en este medio.

Enhancing c-Si Solar Cell Efficiency in the UV Region: Photophysical Insights into the Use of Eu3+ Complexes for Down-Shifting Layer Applications.

[Eu(3DPIQC)3] (where DPIQC = 3-(diphenyl phosphoryl)-1-isoquinolinecarboxylate), a luminescent europium complex with antenna ligands, has been carefully embedded within a polyvinyl butyral (PVB) matrix and the resulting material was used to prepare films used as luminescent down-shifting layers (LDSLs) for crystalline Si-based solar cells. The films were characterized using photoluminescence spectroscopy, atomic force spectroscopy (AFM), UV-Vis spectroscopy, and fluorescence microscopy. The AFM analysis shows films with low surface roughness, while fluorescence microscopy revealed that the Eu complex embedded in PVB assumed a spheroidal configuration, a morphology especially beneficial for optical applications. The so-obtained LDSLs were utilized as energy converters in c-Si solar cells to enhance the utilization of high-energy photons, thereby improving their overall efficiency. The determination of photovoltaic parameters carried out before and after the deposition of the LDSLs on the c-Si cells confirms a positive effect on the efficiency of the cell. The Jsc increases from 121.6 mA/cm2 to 124.9 mA/cm2, and the open circuit voltage (Voc) is found to be unrelated to the complex concentration in the films. The fill factor (FF) remains constant with the Eu concentration. The EQE curves indicate an enhancement in the performance of the photovoltaic cells within the UV region of the spectrum for all coated devices. Electrochemical impedance spectroscopy (EIS) was also carried out in order to analyze the effect of the Eu complex in the charge transfer process of the devices.

c-Si PV module recycling: Analysis of the use of a mechanical pre-treatment to reduce the environmental impact of thermal treatment and enhance materials recovery.

The current increase in the use of photovoltaic (PV) energy demands the search for solutions to recycle end-of-life modules. This study evaluated the use of a mechanical pre-treatment in the thermal recycling of c-Si crystalline PV modules, which were submitted to recycling routes to separate and concentrate the materials of interest. The first route was constituted by only thermal treatment, and the second route was constituted by a mechanical pre-treatment to remove the polymers from the backsheet, and subsequent thermal treatment. The exclusively thermal route was performed at 500°C, varying dwell times between 30 and 120 minutes in the furnace. In this route, the best results were obtained in 90 minutes, with a maximum degradation of 68% of the polymeric mass. In route 2, a micro-grinder rotary tool was used to remove the polymers from the backsheet and, subsequently, thermal treatment performed at 500°C, with dwell times in the furnace ranging between 5 and 30 minutes. The mechanical pre-treatment removed about 10.32 ± 0.92% of the mass of the laminate PV module. By this route, only 20 minutes of thermal treatment were needed for the total decomposition of the polymers, that is, a reduction of 78% in the oven time. With route 2, it was possible to obtain a concentrate with 30 times more silver than the PV laminate and 40 times more than a high-concentration ore. Furthermore, with route 2 it was possible to reduce the environmental impact of heat treatment and energy consumption.

Using compartmental models and Particle Swarm Optimization to assess Dengue basic reproduction number R 0 for the Republic of Panama in the 1999-2022 period.

Nowadays, the ability to make data-driven decisions in public health is of utmost importance. To achieve this, it is necessary for modelers to comprehend the impact of models on the future state of healthcare systems. Compartmental models are a valuable tool for making informed epidemiological decisions, and the proper parameterization of these models is crucial for analyzing epidemiological events. This work evaluated the use of compartmental models in conjunction with Particle Swarm Optimization (PSO) to determine optimal solutions and understand the dynamics of Dengue epidemics. The focus was on calculating and evaluating the rate of case reproduction, R 0 , for the Republic of Panama. Three compartmental models were compared: Susceptible-Infected-Recovered (SIR), Susceptible-Exposed-Infected-Recovered (SEIR), and Susceptible-Infected-Recovered Human-Susceptible-Infected Vector (SIR Human-SI Vector, SIR-SI). The models were informed by demographic data and Dengue incidence in the Republic of Panama between 1999 and 2022, and the susceptible population was analyzed. The SIR, SEIR, and SIR-SI models successfully provided R 0 estimates ranging from 1.09 to 1.74. This study provides, to the best of our understanding, the first calculation of R 0 for Dengue outbreaks in the Republic of Panama.

New approaches to the effects of Si on sugarcane ratoon under irrigation in Quartzipsamments, Eutrophic Red Oxisol, and Dystrophic Red Oxisol.

BACKGROUND: C:N:P homeostasis in plants guarantees optimal levels of these nutrients in plant metabolism. H However, one of the causes to the effects of deficit irrigation is the loss of C:N:P homeostasis in leaves and stems that causes reduction in the growth of sugarcane. Being able to measure the impact of water deficit on C:N:P homeostasis in plants from the stoichiometric ratios of the concentrations of these nutrients in leaves and stems. This loss causes a decrease in nutritional efficiency, but can be mitigated with the use of silicon. Silicon favors the homeostasis of these nutrients and crop productivity. The magnitude of this benefit depends on the absorption of Si by the plant and Si availability in the soil, which varies with the type of soil used. Thus, this study aims to evaluate whether the application of Si via fertigation is efficient in increasing the absorption of Si and whether it is capable of modifying the homeostatic balance of C:N:P of the plant, causing an increase in nutritional efficiency and consequently in the production of biomass in leaves and stems of sugarcane ratoon cultivated with deficient and adequate irrigations in different tropical soils. RESULTS: Water deficit caused biological losses in concentrations and accumulation of C, N, and P, and reduced the nutrient use efficiency and biomass production of sugarcane plants cultivated in three tropical soils due to disturbances in the stoichiometric homeostasis of C:N:P. The application of Si increased the concentration and accumulation of Si, C, N, and P and their use efficiency and reduced the biological damage caused by water deficit due to the modification of homeostatic balance of C:N:P by ensuring sustainability of the production of sugarcane biomass in tropical soils. However, the intensity of attenuation of such deleterious effects stood out in plants cultivated in Eutrophic Red Oxisols. Si contributed biologically by improving the performance of sugarcane ratoon with an adequate irrigation due to the optimization of stoichiometric ratios of C:N:P; increased the accumulation and the use efficiency of C, N, and P, and promoted production gains in biomass of sugarcane in three tropical soils. CONCLUSION: Our study shows that fertigation with Si can mitigate the deleterious effects of deficient irrigation or potentiate the beneficial effects using an adequate irrigation system due to the induction of a new stoichiometric homeostasis of C:N:P, which in turn improves the nutritional efficiency of sugarcane cultivated in tropical soils.

Does computer-assisted navigation improve baseplate screw configuration in reverse shoulder arthroplasty? A systematic review and meta-analysis of comparative studies.

Introduction: Navigation technologies have improved accuracy and precision in positioning glenoid components during shoulder arthroplasty. The influence of navigation on baseplate screw placement has not been independently investigated. This study aimed to evaluate and synthesize the best scientific evidence on the influence of intraoperative navigation on the length and number of screws for primary baseplate fixation in reverse total shoulder arthroplasty procedures. Methods: In August 2022, PubMed, Scopus, and Embase databases were accessed. We analyzed the screw purchase length, the number of screws required for the fixation of the baseplate, and the proportion of cases fixed with two screws in all clinical trials, comparing navigation to standard instrumentation for reverse shoulder arthroplasty. Following an evaluation of the heterogeneity of the studies, DerSimonian-Laird random-effects models were utilized to merge data from separate studies. Results: The systematic search revealed a total of 2034 articles. After excluding duplicates and irrelevant studies, 633 shoulder arthroplasties from 6 trials were included in the analysis. The pooled mean difference in screw purchase length was 5.839 mm (95 %CI 4.496 to 7. 182) in favor of navigation (P < .001). In addition, significant differences were also found in the number of screws per case (- 0.547, 95 %CI -0.890 to -0.203, P = .002) and in the proportion of cases fixed with two screws (Odds Ratio 3.182 95 %CI 1.057 to 9.579, P = .040) in favor of the navigation group. Conclusions: Intraoperative navigation improves the baseplate screw placement, allowing for a greater screw purchase length and fewer screws to achieve primary fixation of the glenoid component during reverse shoulder arthroplasty. It is unclear whether these improvements will increase the longevity of the prosthesis or the clinical outcomes of the patients.

Care for the Self as Government Strategy in Ecovillages / Cuidado de Si como Estratégia de Governo em Ecovilas

ABSTRACT Based on participant observations in two ecovillages the objective of this paper is to uncover the processes of subjectivation embedded in the care for the self in ecovillages that contribute to individual and community development. Our analysis led to the following conclusions: 1) even in different countries, care for the self and others is a government strategy of the ecovillages and had many similarities; 2) work individual issues are a crucial aspect to live in a community, and 3) the infrastructure and demography are important to understanding the processes of subjectivation in the communities. Our analysis also indicates that some level of government is crucial for helping people to take care of themselves.

El amor como sujeto perenne. Una interpretación sobre las concepciones del amor de pareja en el último quinquenio / Love as a perennial subject. An interpretation of conceptions of couple love in the last five years

El amor es un tema que transversaliza al ser humano en todas sus experiencias vitales; es por ello por lo que constantemente está expuesto a contextos colmados de significados, los cuales, de una u otra manera, forjan una idea sobre término, misma que influye directamente en las relaciones de pareja. El presente artículo surge de una investigación reflexiva acerca de las concepciones del amor de pareja en el último quinquenio del siglo XXI y su relación con las formas de amar, lo cual permitió esclarecer, desde lo documental inicialmente, los modos y maneras de relacionamiento en la actualidad. La reflexión transita desde la idea del amor como problema que interesa, pasando por el camino que conduce al sí mismo del amor, entendiendo que este es el problema perenne; finaliza el artículo con la idea de que absolutizar el amor es negarlo

Love is a theme that transverses and crosses human beings in all their life experiences; that is why it is constantly exposed to contexts full of meanings, which, in one way or another, forge an idea about it, which directly influences couple relationships. This article reflects on the conceptions of couple love in the last five years of the 21st century and its relationship with the ways of loving, which allowed us to clarify, initially at a documentary level, the modes, and ways of relating at present. The reflection moves from the idea of love as a problem of interest, passing through the path that leads to love itself, understanding that this is the perennial problem; the article ends with the idea that to absolutize love is to deny it.

Terapia de infidelidad: puente para transitar de la devastación a la re-creación de sí y de la relación / Infidelity therapy: a bridge to transition from the devastation to the renovation of oneself and of the relationship

Objetivo: reconocer las vivencias que tuvieron los consultantes en el proceso terapéutico y que favorecieron mantener la relación de pareja luego de una infidelidad. Metodología: estudio cualitativo, fenomenológico-hermenéutico. Se realizaron dos entrevistas semiestructuradas, a tres parejas y una participante; triangulación de la información con un grupo de discusión con terapeutas. Resultados: las reflexiones suscitadas en el espacio terapéutico llevan a una mirada de sí y de la pareja en términos más compasivos, lo que permite que emerjan transformaciones individuales y relacionales que se denominaron: la renovación de la langosta y la transformación del cristal en oro, respectivamente. Los cambios en el pensamiento, acciones y maneras de relacionarse se constituyeron como prácticas de cuidado de sí y de la pareja. Conclusión: la terapia actúa como un "puente" para la recuperación de las parejas, facilita dejar atrás los efectos devastadores de la infidelidad y florecer en un panorama más estético y esperanzador.

Objective: to recognize the experiences that the consultants had in the therapeutic process that favored maintaining the couple's relationship after an infidelity. Methodology: qualitative study, hermeneutical phenomenological. Two semi-structured interviews were conducted with three couples and one participant; triangulation of information with a discussion group with therapists. Results: the reflections raised in the therapeutic space, lead to a look at oneself and the couple in more compassionate terms, which allows individual and relational transformations to emerge that were called: the renewal of the lobster and the transformation from crystal to gold, respectively. The changes in thinking, actions and ways of relating to each other were constituted as self-care and partner-care practices. Conclusion: therapy acts as a "bridge" for the recovery of couples, it makes it easier to leave behind the devastating effects of infidelity and flourish in a more aesthetic and hopeful outlook.

Masculinidades e aconselhamento nas mídias digitais: subjetivação e empreendedorismo de si em páginas do Instagram / Masculinidades y asesoramiento en medios digitales: subjetivación y emprendedorismo de sí en las páginas de Instagram / Masculinities and counselling in digital media: subjectivation and self-entrepreneurship on Instagram pages

Resumo Este artigo analisa duas páginas do Instagram administradas por influenciadores digitais que apresentam conteúdo reflexivo voltado a homens em torno da construção da masculinidade, buscando compreender as formas de subjetivação imanentes à publicação de conteúdo. A análise se centrou nas descrições biográficas, no conteúdo imagético e audiovisual e no acompanhamento das publicações no perfil e nos stories por um ano. Identificamos que seus temas centrais são o controle das emoções e os relacionamentos conjugais, associados à construção de uma masculinidade denominada "saudável". Seu desenvolvimento passa pelo consumo de práticas terapêuticas oferecidas em cursos e produtos vendidos através da plataforma. O consumo midiático das masculinidades exige, aos seus seguidores, investimentos financeiros e articula-se à lógica do empreendedorismo de si. Busca-se, nesses investimentos, um ideal de sujeito autônomo e autorrealizado consubstanciado na construção individual de uma "masculinidade saudável".

Abstract This article analyses two Instagram pages managed by digital influencers who present reflexive content for men about the construction of masculinity. It addresses the forms of subjectivation immanent in the content publicised. The analysis was focused on biographical descriptions, imagery and audiovisual content, and monitoring of posts in their user profile and stories during one year. The themes identified as central were the control of emotions and romantic relationships, associated with the construction of the so-called "healthy masculinity". That construction requires the consumption of therapeutic practices offered in courses and products through the platform. The media consumption of masculinities requires, from their followers, financial investments and it is articulated to the logic of entrepreneurship of the self. Those investments work towards an ideal of autonomous and self-realised subject embodied in the individual construction of a "healthy masculinity".

Reflexões sobre a formação acadêmica na educação física à luz das tecnologias de si em Foucault / Reflexiones sobre la formación académica en educación física a la luz de las tecnologías del yo en Foucault / Reflections about academic formation in physical education on the light of technologies of self in Foucault

Este artigo busca respaldo nas concepções foucaultianas de ética e estética da existência para compor reflexões sobre a formação acadêmica na Educação Física. Como guisa à mobilização desse intento, se contextualiza a noção de "tecnologias de si", encontrada na última etapa da obra de Michel Foucault. Na sequência, traçam-se aproximações, heterogêneas e diferenciais, entre a problemática ética colocada à constituição do sujeito e a formação acadêmica. Ainda que essas aproximações devam ser vistas com cautela - para não tomar as práticas de constituição dos sujeitos antigos como origem longínqua para forjar e explicar um modelo formativo para os sujeitos modernos - tais aproximações apontam para outras racionalidades não-hegemônicas que se contrapõem às lógicas capacitativas comumente atribuídas à formação acadêmica, que tendem a ser reduzidas apenas a seus aspectos instrumentais. Deste modo, as reflexões que aqui se avizinham não afirmam teorias gerais, tampouco verdades boas ou ruins sobre a formação, mas dão visibilidade para a composição de práticas discursivas e não-discursivas alternativas de elaboração e lapidação de si, estabelecidas nos jogos de força que as sustentam ao longo do percurso formativo.

Este artículo busca apoyo en las concepciones de Foucault sobre ética y estética de la existencia para reflexionar sobre la formación académica en Educación Física. Como guía para esta reflexión, se contextualiza la noción de 'tecnologías del yo', que se encuentra en la última etapa de la obra de Michel Foucault. Posteriormente, se establecen aproximaciones heterogéneas y diferenciales entre la cuestión ética planteada en la constitución del sujeto y la formación académica. Aunque estas aproximaciones deben ser vistas con cautela - para no considerar las prácticas de constitución de sujetos antiguos como un origen lejano para forjar y explicar un modelo formativo para los sujetos modernos - tales aproximaciones apuntan a otras racionalidades no hegemónicas que se oponen a las lógicas capacitativas comúnmente atribuidas a la formación académica, que tienden a reducirse a sus aspectos instrumentales. De esta forma, las reflexiones que aquí se adelantan no afirman teorías generales ni verdades absolutas sobre la formación, pero dan visibilidad a la composición de prácticas alternativas, discursivas y no discursivas, de elaboración y transformación del yo, establecidas en los juegos de fuerza que las sustentan a lo largo del camino de la formación.

This article seeks support in Foucault's conceptions of ethics and aesthetics of existence to compose reflections on academic training in Physical Education. As a way to mobilize this intent, the notion of "technologies of the self", found in the last stage of Michel Foucault's work, is contextualized. Next, heterogeneous and differential approximations are outlined between the ethical problem posed to the constitution of the subject and academic training. Although these approximations must be seen with caution - in order not to take the constitution practices of ancient subjects as a distant origin to forge and explain a formative model for modern subjects - such approximations point to other non-hegemonic rationalities that oppose the enabling logics commonly attributed to academic training, which tend to be reduced to its instrumental aspects only. In this way, the reflections ahead here do not affirm general theories, nor good or bad truths about training, but give visibility to the composition of alternative discursive and non-discursive practices of elaboration and shaping of the self, established in the power dynamics that support them throughout the formative journey.
