The moderating effect of perceived punishment on the relationship between the Dark Triad and corruption

The present study aimed to investigate the moderating effect of perceived punishment on the relationship between the Dark Triad personality traits and corruption in Brazil (N = 118) and the United Kingdom (N = 130). Participants answered the Dark Triad Dirty Dozen Scale, as well as measures of corruption and perceived punishment. It was found that punishment predicts corruption in both countries. Regarding the Dark Triad traits, a relationship between Machiavellianism and corruption was identified in Brazil and the United Kingdom, although an interaction with punishment was identified only in Brazil. Moreover, psychopathy had no relationship with corruption or punishment in either country. A direct relationship was found only in Brazil on narcissism, although the interaction term was significant in both countries. In general, it was identified that perceived punishment and the dark triad traits contribute to the understanding of corruption, despite some differences in the results between Brazil and the United Kingdom.

O presente estudo tem como objetivo investigar o papel moderador da percepção de punição na relação entre Tríade Sombria da personalidade e corrupção no Brasil (N = 118) e no Reino Unido (N = 130). Participantes responderam à Escala Dark Triad Dirty Dozen, bem como a medidas de corrupção e percepção de punição. Foi encontrado que a punição prediz a corrupção em ambos os países. Em relação à Tríade Sombria, o relacionamento entre maquiavelismo e corrupção foi identificado no Brasil e no Reino Unido, embora a interação com a punição tenha sido identificada apenas no Brasil. Adicionalmente, a psicopatia não teve relação com a corrupção ou com a punição em nenhum dos países. Um efeito direto do narcisismo foi encontrado apenas no Brasil, apesar do termo de interação ter sido significativo em ambos os países. De forma geral, foi identificado que a percepção de punição e a tríade sombria contribuíram com a compreensão da corrupção, apesar de algumas diferenças nos resultados entre Brasil e Reino Unido.

El presente estudio tuvo como objetivo investigar el efecto moderador del castigo percibido sobre la relación entre los rasgos de personalidad de la tríada oscura y la corrupción en Brasil (N = 118) y en el Reino Unido (N = 130). Los participantes respondieron a la Escala de la Docena Sucia de la Triada Oscura, así como a medidas de corrupción y castigo percibido. Se encontró que el castigo predice la corrupción en ambos países. En cuanto a los rasgos de la tríada oscura, se identificó una relación entre el maquiavelismo y la corrupción en Brasil y en el Reino Unido, aunque se identificó una interacción con el castigo solo en Brasil. Además, la psicopatía no tuvo relación con la corrupción o el castigo en ninguno de los dos países. Se encontró una relación directa solo en Brasil con el narcisismo, aunque la interacción fue significativa en ambos países. En general, se identificó que el castigo percibido y los rasgos de la tríada oscura contribuyen a la comprensión de la corrupción, a pesar de algunas diferencias en los resultados entre Brasil y el Reino Unido.

Makeup Usage in Women Is Positively Associated to Narcissism and Extraversion but Negatively to Psychopathy.

Appearance modification practices are ubiquitous, serving to enhance physical attractiveness and accrue social advantages, including increased desirability as a potential mate. Facial cosmetics are frequently used for appearance modification, yet individual differences in makeup usage remain understudied. While makeup usage in women has been linked to traits like narcissism and extraversion, the broader association with Dark Triad traits and how personality influences makeup application across diverse social contexts were less explored. Here we examined these relationships in 1,410 Brazilian women (Mage = 29.9, SD = 10.35), who completed online Big Five and Dark Triad personality measures, reported their usual makeup usage habits, and detailed their makeup usage across different social scenarios. Results revealed makeup usage was positively associated with narcissism and extraversion, and negatively with psychopathy. Additionally, women used less makeup when alone (at home, exercises) and more in social settings, particularly for the first date. However, women with higher narcissism and neuroticism showed larger differences among low and high makeup usage situations, while individuals with higher psychopathy used makeup in similar frequencies among different situations. Further, (1) overall greater users of makeup scored higher on narcissism, conscientiousness, and agreeableness; (2) average users displayed lower psychopathy; and (3) lesser users reported lower narcissism and higher psychopathy. These findings underscore the nuanced relationship between makeup usage and personality, particularly highlighting the influence of narcissism. These findings contribute to the interplay between personality traits and makeup usage, considering interindividual differences and intraindividual variation in understanding cosmetic behaviors among women.

3-Chymotrypsin-like Protease (3CLpro) of SARS-CoV-2: Validation as a Molecular Target, Proposal of a Novel Catalytic Mechanism, and Inhibitors in Preclinical and Clinical Trials.

Proteases represent common targets in combating infectious diseases, including COVID-19. The 3-chymotrypsin-like protease (3CLpro) is a validated molecular target for COVID-19, and it is key for developing potent and selective inhibitors for inhibiting viral replication of SARS-CoV-2. In this review, we discuss structural relationships and diverse subsites of 3CLpro, shedding light on the pivotal role of dimerization and active site architecture in substrate recognition and catalysis. Our analysis of bioinformatics and other published studies motivated us to investigate a novel catalytic mechanism for the SARS-CoV-2 polyprotein cleavage by 3CLpro, centering on the triad mechanism involving His41-Cys145-Asp187 and its indispensable role in viral replication. Our hypothesis is that Asp187 may participate in modulating the pKa of the His41, in which catalytic histidine may act as an acid and/or a base in the catalytic mechanism. Recognizing Asp187 as a crucial component in the catalytic process underscores its significance as a fundamental pharmacophoric element in drug design. Next, we provide an overview of both covalent and non-covalent inhibitors, elucidating advancements in drug development observed in preclinical and clinical trials. By highlighting various chemical classes and their pharmacokinetic profiles, our review aims to guide future research directions toward the development of highly selective inhibitors, underscore the significance of 3CLpro as a validated therapeutic target, and propel the progression of drug candidates through preclinical and clinical phases.

The impact of Benevolent Childhood Experiences on adult Flourishing: the mediating role of Light Triad traits.

The literature has well documented the relationship between Adverse Childhood Experiences, personality traits, and well-being. However, less is known about how Benevolent Childhood Experiences (BCEs) relate to "light" personality traits and Flourishing. The study analyzed the effects of BCEs on Flourishing, considering the mediator role of Light Triad traits (Kantianism, Humanism, and Faith in Humanity). The study used a quantitative methodology with a non-experimental, cross-sectional design; 410 Honduran adults responded to the survey, including questions regarding Light Triad personality traits, Flourishing, and BCEs. On average, respondents reported 7.34 BCEs. The number of reported BCEs did not vary significantly between men and women. However, specific BCEs were categorically associated with subjects' sex. A higher proportion of men reported having at least one teacher who cared about the respondent, having opportunities to have a good time, and liking/feeling comfortable with oneself. Flourishing was significantly higher for participants who reported the presence of BCEs. The largest effect size was achieved for the difference in Flourishing scores between those who reported liking school as a child and those who disliked it. The number of Benevolent Childhood Experiences had a significant total and direct effect on Flourishing scores. Significant indirect effects were also identified. Faith in Humanity and Humanism, not Kantianism, mediated the relationship between BCEs and Flourishing. BCEs significantly explained all Light Triad traits. In conclusion, BCEs have significant direct and indirect effects on adult Flourishing; Faith in Humanity and Humanism mediate this relationship.

A Network Analysis Approach to Understanding Centrality and Overlap of 21 Dark Triad Items in Adults of 10 Countries.

Background: Previous research has suggested that manipulation and callousness are central to Dark Triad traits, but it has not identified which specific manifestations are expressed across various countries. Objective: This study aimed to identify the core and overlapping manifestations of Dark Triad traits across 10 countries. Methods: We used the Short Dark Triad (SD3) scale and assessed a sample of 8093 participants (59.7% women, M(age) = 32.68 years). For graphical representation, the spinglass algorithm was applied to understand the cluster distribution among Machiavellianism, psychopathy, and subclinical narcissism traits. Centrality indices were used to identify the most influential items, and the clique-percolation algorithm was employed to detect shared attributes among multiple Dark Triad items. Results: Straightforward SD3-21 items demonstrated better interpretability as aversive traits within the broader system. Items with higher centrality values were those related to short-term verbal manipulation from the psychopathy domain, clever manipulation, strategic revenge-seeking from Machiavellianism, and narcissistic motivations for connecting with significant individuals. The most predicted items were linked to planned revenge, using information against others from Machiavellianism, short-term psychopathic verbal manipulation, and narcissistic belief of specialness based on external validation. Items like short-term verbal manipulation had overlaps with both psychopathy and narcissism clusters, while clever manipulation overlapped with Machiavellianism and psychopathy. Conclusion: This cross-cultural study highlights the central role of verbal manipulation within the Dark Triad traits, along with identifying overlapping items among traits measured using straightforward SD3 scale items. In line with our findings, future research that incorporates a wide range of cultural contexts is encouraged to establish the consistency of these findings with the SD3 Scale or alternative measures.

Gender-based differences in the impact of Dark Triad traits on academic dishonesty: The mediating role of moral disengagement in college students.

This study explores whether gender differences influence the components of the Dark Triad of personality and moral disengagement on the manifestations of dishonest academic behavior in Peruvian university students. Moreover, it evaluates how moral disengagement mediates the effect that the Dark Triad components have on academic dishonesty. The participants were 591 university students, aged between 18 and 40 years (women = 71.7 %; Mage = 21.5; SDage = 3.60), to whom the Dirty Dozen Dark Triad, the Propensity to Morally Disengage Scale, and the Scale of Academic Dishonesty, which has 3 dimensions (cheating on exams, plagiarism, and falsification) were applied. The results reveal that only Machiavellianism has a significant and consistent influence on all dimensions of academic dishonesty, in both men and women, while psychopathy influences the dimension of plagiarism in both men and women and falsification only in men. In addition, moral disengagement affects falsification in both groups, cheating on exams only in the men's group, and plagiarism in the women's group. Finally, the mediating role of moral disengagement between the effect of the Dark Triad and the manifestations of academic dishonesty was not demonstrated.

Centralidad y asociaciones entre la tríada oscura, inteligencia emocional rasgo y distancia social durante la pandemia de COVID-19 en Perú: un análisis de redes

Pocos estudios en Sudamérica han examinado rasgos de personalidad que tuvieron impacto a nivel individual y social durante la pandemia. El objetivo del estudio fue identificar las variables centrales y asociaciones parciales en una red entre la tríada oscura, inteligencia emocional rasgo y distancia social durante la pandemia, y variables demográficas. Se hipotetizó a la edad como posible variable central en la red, y la relación negativa entre la tríada oscura con la distancia social y la inteligencia emocional rasgo, excepto el narcisismo. Se utilizó un muestreo no probabilístico donde participaron 311 adultos (M = 33.95 años, 65 % mujeres). Mediante encuestas en línea, se aplicaron las escalas Dirty Dozen Dark Triad, Trait Meta-Mood Scale y datos demográficos. La atención emocional fue clave al conectar la tríada oscura y la inteligencia emocional. Además, favoreció la adherencia a la distancia social, mientras lo inverso sucedió con el maquiavelismo. Los dominios de la tríada oscura e inteligencia emocional tuvieron asociación negativa, excepto por el narcisismo, que mostró una conexión positiva con la atención emocional. En síntesis, durante la pandemia, la evaluación de la atención a las emociones fue crucial para entender las motivaciones aversivas sociales y promover la adhesión al distanciamiento social. En contraste, debe investigarse más el maquiavelismo, que se asoció a los jóvenes, y no contribuyó a la normativa social de salud pública.

Poucos estudos na América do Sul examinaram os traços de personalidade que foram impactados a nível individual e social durante a pandemia. O objetivo do estudo foi identificar as variáveis centrais e associações parciais em uma rede entre a tríade sombria, o traço de inteligência emocional, o distanciamento social durante a pandemia e variáveis demográficas. As hipóteses foram de que a idade era uma possível variável central na rede, e de que havia uma relação negativa entre a tríade sombria e o distanciamento social e o traço de inteligência emocional, exceto para o narcisismo. Foi utilizado um método de amostragem não probabilístico, com a participação de 311 adultos (M = 33,95 anos, 65 % mulheres). Por meio de pesquisas online, foram aplicadas as escalas Dirty Dozen Dark Triad, Trait Meta-Mood Scale e dados demográficos. A atenção emocional foi fundamental ao conectar a tríade sombria e a inteligência emocional. Além disso, favoreceu a adesão ao distanciamento social, enquanto o inverso foi observado com o maquiavelismo. Os domínios da tríade sombria e da inteligência emocional tiveram associação negativa, exceto pelo narcisismo, que apresentou uma conexão positiva com a atenção emocional. Em resumo, durante a pandemia, a avaliação da atenção às emoções foi crucial para compreender as motivações sociais aversivas e promover a adesão ao distanciamento social. Em contraste, é necessário investigar mais o maquiavelismo, que se associou aos jovens, e não contribuiu para as normativas sociais de saúde pública.

Few studies in South America have examined personality traits that had an impact at an individual and social level during the pandemic. The aim of the study was to identify the most central variables and partial associations in a network among the dark triad, trait emotional intelligence, social distancing during the pandemic, and demographic variables. Age was hypothesized as a possible central variable in the network, and a negative relationship was found between the dark triad and social distancing and trait emotional intelligence, except for narcissism. A non-probabilistic sampling method was used, with 311 adults (M = 33.95 years, 65 % women). Online surveys as the Dirty Dozen Dark Triad, Trait Meta-Mood Scale, and demographic data were used. Emotional attention played a key role in linking the dark triad and emotional intelligence. Moreover, it favored adherence to social distancing, while the reverse was observed with Machiavellianism. Finally, dark triad and emotional intelligence domains showed a negative association, except for narcissism, which had a positive connection with emotional attention. In summary, during the pandemic, assessing emotional attention was crucial to comprehend social aversive motivations and promote adherence to social distancing. In contrast, Machiavellianism, associated with the youth, needs further investigation and did not contribute to public health social norms.

Postoperative Functional Evaluation in Patients Undergoing Surgical Treatment of the Terrible Triad Injury of the Elbow.

Objective To evaluate the functional results of patients submitted to a surgical approach for the treatment of the terrible triad of the elbow, analyzing the treatment methods used and associated epidemiological variables. Methods Patients who underwent surgical treatment for the terrible triad of the elbow from February 2018 to June 2020 at our service were evaluated. The identified sample consisted of 17 patients, but of these, only 13 completed all stages of the study and, therefore, were considered as the universe to be considered. Epidemiological information of interest was collected: age, sex, hand of dominance, affected side, characteristics and classification of injuries, trauma mechanism, time to surgery, type of procedure performed and range of motion. The Mason classification was used for radial head fractures and the Regan and Morrey classification for the coronoid process. In order to perform a functional analysis, the DASH and BRUCE questionnaires were applied. Results About 77% of the patients were male, 92% of the fracture mechanisms were due to high-energy trauma. Contrary to this, the predominance of the non-dominant side was observed as the most affected. Evaluating the results according to the time to start the treatment, the patients operated within 14 days had statistically better functional results. Conclusion Surgical treatment of TTIE generates acceptable functional results in most cases. The success of the treatment is related to the time interval between the trauma and the first surgery, in addition to the severity of the injuries.

O núcleo da tríade sombria prediz o ambientalismo por meio da orientação à dominância social

O presente estudo objetivou verificar o papel mediador da orientação à dominância social na relação entre o núcleo da tríade sombria da personalidade e o ambientalismo. Participaram 305 pessoas com idades entre 18 e 77 anos (Midade = 26,4; DPidade = 11,25; 59,7 % mulheres). Os resultados indicaram que entre os 8 traços de personalidade analisados, considerando os modelos dos Cinco Grandes Fatores e da Tríade Sombria, apenas a psicopatia se correlacionou com ambientalismo, sendo que este se correlacionou moderadamente com a orientação à dominância social. Considerando que os três traços sombrios são talhados por déficits empáticos, baixa amabilidade e honestidade/humildade, testou-se o efeito do núcleo da tríade sombria da personalidade para a predição do ambientalismo, observando-se efeitos diretos. Contudo, tais efeitos diretos não se mantiveram estatisticamente significativos com a inclusão da orientação à dominância social, configurando uma mediação completa, posto que o núcleo da tríade sombria predisse indiretamente o ambientalismo. Logo, observa-se que a orientação à dominância social funciona como um mecanismo que possibilita pessoas com traços sombrios não se preocuparem com o meio ambiente, explorando-o em benefício próprio.

El presente estudio tuvo como objetivo verificar el papel mediador de la orientación a la dominancia social en la relación entre el núcleo de la tríada oscura y el ambientalismo. Participaron 305 personas con edades comprendidas entre 18 y 77 años (Medad = 26,4; DEedad = 11,25; 59,7 % mujeres). Los resultados indicaron que, entre los 8 rasgos de personalidad analizados considerando los modelos Big Five y Dark Triad, solo la psicopatía se correlacionó con el ambientalismo, que se correlacionó moderadamente con la orientación a la dominancia social. Considerando que los tres rasgos oscuros comparten déficits empáticos, baja amabilidad y honestidad/humildad, se probó el efecto del núcleo de la tríada oscura para la predicción del ambientalismo y se observaron efectos directos. Sin embargo, tales efectos directos no fueron estadísticamente significativos con la inclusión de la orientación a la dominancia social, configurando una mediación completa, ya que el núcleo oscuro predice indirectamente el ambientalismo. Por lo tanto, se observa que la dominancia social funciona como un mecanismo que permite a las personas con rasgos oscuros no preocuparse por el medio ambiente y explotarlo en beneficio propio.

The present study aimed to verify the mediating role of social dominance orientation in the relationship between the core of the dark triad and environmentalism. Participants were 305 people aged between 18 and 77 years old (Mage = 26.4; SDage = 11.25; 59.7 % women). The results indicated that among the 8 personality traits analyzed, considering the Big Five and Dark Triad models, only psychopathy was correlated with environmentalism, which was moderately correlated with social dominance orientation. Considering that the three dark traits shared empathic deficits, low agreeableness and honesty/humility, the effect of the dark triad core was tested for the prediction of environmentalism, observing direct effects. However, such direct effects did not remain statistically significant with the inclusion of social dominance orientation, configuring a complete mediation, since the dark core indirectly predicted environmentalism. Therefore, it is observed that social dominance orientation works as a mechanism that allows people with dark traits not to worry about the environment, exploiting it for their own benefit.

La relación de los factores de personalidad y la conducción agresiva: los Cinco Grandes y la Tríada Oscura / The Relationship between Personality Traits and Aggressive Driving: The Big Five and the Dark Triad

Resumen El objetivo de esta investigación fue analizar el papel que los factores de personalidad pertenecientes a los Cinco Grandes y la Tríada Oscura -maquiavelismo, narcisismo y psicopatía- tienen en la conducción agresiva. La muestra se compuso de 318 estudiantes universitarios con permiso de conducir, quienes contestaron a una batería de pruebas que evaluaba los factores de personalidad de los Cinco Grandes (TIPI), la Tríada Oscura (DD) y la conducción agresiva (DAS y DAX). Los análisis de regresión jerárquica controlando las variables de edad y sexo, respaldan la utilidad predictiva de los factores de personalidad de los Cinco Grandes y la Tríada Oscura. Los resultados mostraron cómo la afabilidad, la estabilidad emocional y la apertura a la experiencia predicen de manera significativa diversos aspectos de la conducción agresiva. El maquiavelismo y el narcisismo son predictores significativos de diversas formas de expresión de la ira en la conducción, una vez controlados los efectos de los Cinco Grandes.

Abstract The aim of this paper was to analyze the role that personality traits belonging to the Big Five and the Dark Triad (Machiavellianism, narcissism, and psychopathy) have on aggressive driving. 318 undergraduate students with a driver's license completed a battery of tests assessing Big Five personality traits (TIPI), Dark Triad (DD) and aggressive driving (DAS and DAX). Hierarchical regressions analyses controlling for respondents' age and gender variables supported the predictive utility of the Big Five personality traits and the Dark Triad. Results showed that agreeableness, emotional stability and openness to experience predict various aspects of aggressive driving. Machiavellianism and narcissism are significant predictors of various forms of anger expression in driving after controlling for the effects of the Big Five personality traits.

Postoperative Functional Evaluation in Patients Undergoing Surgical Treatment of the Terrible Triad Injury of the Elbow / Avaliação funcional pós-operatória em pacientes submetidos a tratamento cirúrgico da tríade terrível do cotovelo

Resumo Objetivo Avaliar os resultados funcionais dos pacientes submetidos a abordagem cirúrgica para o tratamento da tríade terrível do cotovelo, analisando os métodos de tratamento utilizados e variáveis epidemiológicas associadas. Métodos Foram avaliados pacientes submetidos aotratamento cirúrgico de tríade terrível do cotovelo de fevereiro de 2018 a junho de 2020 em nosso serviço. A amostra identificada foi de 17 pacientes, mas destes apenas 13 concluíram todas as etapas das pesquisas e por isso foram considerados como o universo a ser levado em consideração. Coletou-se informações epidemiológicas de interesse: idade, sexo, dominância, lado acometido, características e classificações das lesões, mecanismo do trauma, tempo para cirurgia, tipo de procedimento realizado e o arco de movimento. Foi utilizada a classificação de Mason para a fratura de cabeça do rádio e a de Regan e Morrey, para o processo coronoide. A fim de realizar uma análise funcional, aplicou-se os questionários de DASH e BRUCE. Resultados Cerca de 77% dos pacientes foram do sexo masculino, 92% dos mecanismos de fratura foram por trauma de alta energia. Contrariamente a esta, observou-se a predominância do lado não dominante como o mais afetado. Avaliando os resultados de acordo com o tempo para início do tratamento, os pacientes operados em até 14 dias obtiveram resultados funcionais estatisticamente melhores. Conclusão O tratamento cirúrgico da TTC gera resultados funcionais aceitáveis na maioria dos casos. O sucesso do tratamento está relacionado ao intervalo de tempo entre o trauma e a primeira cirurgia, além de se relacionar com a gravidade das lesões.

Sexismo y tríada oscura de la personalidad en adolescentes: el rol mediador de la desconexión moral / Sexism and dark triad of personality on adolescents: the mediator role of moral disengagement

Resumen Introducción: La Organización Mundial de la Salud indica que es necesario eliminar los valores, las actitudes y los estereotipos basados en el género que afectan la salud y el bienestar de las niñas y mujeres en el mundo. Desde la psicología de la personalidad, algunos trabajos científicos han demostrado que rasgos como la triada oscura de la personalidad (maquiavelismo, psicopatía y narcisismo) y la desconexión moral aumentan la susceptibilidad al sesgo de género, la amenaza y la agresión interpersonal. Como contribución al diseño de un perfil personológico propenso a aceptar y justificar las actitudes sexistas, el objetivo principal de este trabajo fue estudiar el rol mediador de la desconexión moral entre la triada oscura de la personalidad y el sexismo ambivalente en adolescentes. Método: La muestra estuvo compuesta por 803 adolescentes (M = 15.33, DT = 0.99; 50.3% chicos) tras utilizar un muestreo por conveniencia para realizar un análisis de la varianza y la comparación de varios modelos mediacionales a partir de la técnica de bootstrapping. Resultados: Los rasgos de la triada oscura de la personalidad se relacionan directa y significativamente con el sexismo hostil y benevolente de los/as adolescentes, y la desconexión moral tiene un efecto mediador importante en esta relación. Conclusiones: Finalmente, se discute cómo trabajar la desconexión moral para la transformación de estas creencias y actitudes de género que perpetúan la discriminación hacia las adolescentes en programas de prevención.

Abstract Introduction: The World Health Organization indicates that gender-based values, attitudes and stereotypes that affect the health and well-being of girls and women around the world need to be eliminated. From personality psychology, scientific studies have shown that traits such as the dark personality triad (Machiavellianism, psychopathy, and narcissism) and moral disengagement increase susceptibility to gender bias, threat, and interpersonal aggression. As a contribution to the design of a personological profile prone to accept and justify sexist attitudes, the main aim of this paper was to study the mediating role of moral disengagement between the dark personality triad and ambivalent sexism in a sample of adolescents. Methods: The sample consisted of 803 adolescents (M = 15.33, SD = 0.99; 50.3% boys) using convenience sampling to assess ambivalent sexism, dark personality triad and moral disengagement. An analysis of variance and comparison of various mediational models was carried out using the bootstrapping technique. Results: The dark personality triad traits are directly and significantly related to adolescents' hostile and benevolent sexism, and that moral disengagement has a relevant mediating effect on this relationship. Conclusions: Finally, the implications of these findings for the transformation of these gendered beliefs and attitudes that perpetuate discrimination against girls and women are discussed in relation with prevention programs.

Stress fractures.

Stress fractures (SF) represent 10%-20% of all injuries in sport medicine. An SF occurs when abnormal and repetitive loading is applied on normal bone: The body cannot adapt quickly enough, leading to microdamage and fracture. The etiology is multifactorial with numerous risk factors involved. Diagnosis of SF can be achieved by identifying intrinsic and extrinsic factors, obtaining a good history, performing a physical exam, and ordering laboratory and imaging studies (magnetic resonance imaging is the current gold standard). Relative energy deficiency in sport (RED-S) is a known risk factor. In addition, for women, it is very important know the menstrual status to identify long periods of amenorrhea in the past and the present. Early detection is important to improve the chance of symptom resolution with conservative treatment. Common presentation involves complaints of localized pain, with or without swelling, and tenderness on palpation of bony structures that begins earlier in training and progressively worsens with activity over a 2- to 3-week period. Appropriate classification of SF based on type, location, grading, and low or high risk is critical in guiding treatment strategies and influencing the time to return to sport. Stress injuries at low-risk sites are typically managed conservatively. Studies have suggested that calcium and vitamin D supplementation might be helpful. Moreover, other treatment regimens are not well established. Understanding better the pathophysiology of SFs and the potential utility of current and future bone-active therapeutics may well yield approaches that could treat SFs more effectively.

The dark side of sexism in Argentina: Psychometric properties of the Short Dark Triad Personality measure and its relation with ambivalent sexism.

One of the main evaluation instruments of the dark side of personality has been the Short Dark Triad of Personality (SD3), that includes Machiavellianism, Narcissism and Psychopathy traits. Although other adaptations of this scale have been made in several countries, its psychometric properties have never been tested in Argentina. Different studies addressed that dark triad scores are related to different expressions of sexist prejudice. One of the issues that have been traditionally considered to understand intimate, yet unequal relationships between men and women, is prejudice toward women. Ambivalent sexism combines two types of sexist attitudes: hostile, and benevolent sexism. While hostile sexism involves attitudes of outright intolerance towards women, benevolent sexism is defined as a set of attitudes that comprises the perception of women in a positive emotional tone. The aim of the study was to analyze the Dark Triad of Personality scale in the Argentinian context and its relationships whit ambivalent sexism. A total of 1,198 individuals residing in different regions of Argentina participated, from different genders (woman = 59.5%), from 18 to 75 years old (M = 45.17 SD = 15.08). Main results indicated adequate psychometric properties for the Short Dark Triad of Personality scale in the Argentinian context. In addition, the three traits of the dark triad were significantly related to hostile and benevolent sexism, which indicate that one of the variables to keep addressing in order to comprise and eventually reduce prejudice towards women would be the dark triad of personality. Main results are discussed, in order to strengthen the understanding of the relationships between the dark triad and ambivalent sexism.

A Catastrophic Complication of Thoracic Endovascular Aortic Repair: Aortoesophageal Fistula.

A 62-year-old man was admitted to the hospital due to sepsis secondary to a hemodialysis catheter-related infection that, upon diagnostic evaluation, demonstrated to be caused by P. aeruginosa and was treated with meropenem. Eradication of the infectious episode was confirmed by blood workup, including cultures. One month after the initial episode, the patient was readmitted due to a symptomatic penetrating aortic ulcer, which was classified as a cardiovascular emergency. The patient underwent an aortic stent-graft placement. Four weeks later, he presented to the emergency department with a 2-hour onset of thoracic pain and massive hematemesis. The esophagus and aortic segment with aortic stent graft were resected en bloc after an aortoesophageal fistula was diagnosed.

Problemas emocionales, personalidad oscura, sexting y grooming en adolescentes: el rol del género y la edad / Emotional Problems, Dark Personality, Sexting and Grooming in Adolescents: the role of Gender and Age

Resumen El presente estudio tuvo como objetivo estudiar si los problemas emocionales (depresión y ansiedad) y la Personalidad Oscura eran predictores del sexting y el grooming, y si este comportamiento varía según el género y la edad. Se constituyó una muestra de 728 adolescentes entre 11 y 18 años (38% hombres) de tres escuelas secundarias privadas ubicadas en Buenos Aires y Paraná, Argentina. Completaron un Cuestionario de sexting, el Cuestionario de Solicitación e Interacción Sexual a menores online por parte de adultos para evaluar el comportamiento de grooming, la Escala de síntomas psicosomáticos de Rosenberg, el Inventario de depresión de Kovacs para niños y el Dirty Dozen para los rasgos de Personalidad Oscura. Los resultados mostraron que 12% de los adolescentes admitió haber padecido una conducta de grooming. Las formas más frecuentes fueron el envío de mensajes escritos de carácter sexual (11%) y fotos (10%) y luego, en orden de frecuencia, el envío de videos (4%), pero no se detectaron diferencias por género. Los predictores significativos de sexting y el tamaño de su varianza explicada variaban según el género (R² = 47% para mujeres y R² = 12% para hombres, respectivamente). En el caso de las mujeres, mayor edad y puntajes de psicopatía fueron predictores significativos, y en el de los hombres, menor ansiedad fue el predictor significativo. Un modelo estructural explicó una varianza del 6% para el sexting y 21% para el grooming, indicando que no hubo invarianza, según el género. Las regresiones lineales para predecir el grooming a partir del sexting también sugirieron que el género moderaba esta relación.

Abstract The present study aimed to study if emotional problems (depression and anxiety) and Dark Personality were predictors of sexting and grooming, and if this behavior differs by gender and age. A sample of 728 adolescents between 11 and 18 years of age (38% male) from three private high schools located in Buenos Aires and Paraná, Argentina, was drawn. They completed a Sexting questionnaire, the Questionnaire for Online Sexual Solicitation and Interaction of Minors with Adults for grooming behavior, Rosenberg Scale of Psychosomatic Symptoms, the Kovacs Depression Inventory for Children and the Dirty Dozen for dark personality traits. Results showed that 12% of adolescents admitted having carried out a sexting behavior. Sending written messages of a sexual nature (11%) and photos (10%) were the most prevalent ways, followed by videos (4%), but no differences were detected according to gender. Significant predictors of sexting and the size of its explained variance ranged by gender (R² = 47% for females and R² = 12% for men, respectively). In the case of females, older age and psychopathy were the significant predictors. In the case of males, less anxiety was the significant predictors. A structural model explained a variance of 6% for sexting and 21% for grooming, indicating that there was no inavariance, according to gender. Linear regressions to predict grooming from sexting also suggested this relationship was moderated by gender.

Environmental analysis of the eutrophication and spread of aquatic macrophytes in a tropical reservoir: a case study in Brazil.

Land use changes threaten the maintenance of water quality and challenge the management of tropical reservoirs. In particular, eutrophication alters several ecosystem functions and services, compromising multiple uses of water. For example, in the Lajeado Reservoir (Araraquara, São Paulo, Brazil), aquatic macrophytes rapidly spread and occupied more than 90% of the system's surface area (from 2016 to 2019). In such a scenario, this research aimed to evaluate the eutrophication causes and impacts to provide technical and scientific support to public agencies and propose remediation alternatives. First, a diagnosis of the study area was performed, using available data on land use, water quality, and climate (between 2010 and 2018). Second, water and sediment samples were collected for physical, chemical, and ecotoxicological analyses. The Ecological Risk Assessment consisted of a triad of Lines of Evidence, including physical-chemical, chemical, and ecotoxicological results. The expansion of agricultural activities (e.g., sugarcane cultivation) and diffuse pollution were highlighted among possible causes, and water quality was affected by increases in the concentration of nutrients (e.g., nitrogen and phosphorus), metals (e.g., iron), and emerging contaminants (e.g., pesticides and caffeine). As a result, the Lajeado Reservoir presented a high ecological risk, and alternatives for macrophyte removal are needed. This research involved several stakeholders (i.e., community, government agencies, and universities) who participated more effectively in environmental monitoring and recovery.

Condroma pulmonar y paraganglioma carotídeo como manifestaciones de la tríada de Carney: reporte de un caso / Pulmonary chondroma and carotid paraganglioma as expressions of Carney's triad: report of a case

Resumen Objetivos: Presentar caso clínico y revisión de la literatura sobre asociación de tumores poco frecuentes compatibles con diagnóstico de tríada de Carney. Paciente y Métodos: Revisión de ficha clínica de paciente de sexo femenino de 39 años de edad con antecedentes de asma, quien acude a servicio de urgencias por síntomas respiratorios. En estudio con imágenes se evidencia masa pulmonar en lóbulo superior derecho probablemente hamartoma y masa en la bifurcación carotídea izquierda compatible con posible paraganglioma. Se completó el estudio con endoscopia digestiva alta sin evidencia de tumor gástrico y PET-CT (tomografía de emisión de positrones-tomografía computarizada) que descartó otras lesiones. Resultados: La paciente fue sometida a resección quirúrgica de ambos tumores (pulmonar y carotídeo). En estudio histopatológico diferido, se plantean los diagnósticos de paraganglioma carotideo y hamartoma pulmonar, el cual, luego de una segunda revisión histopatológica, es corregido a condroma pulmonar. Discusión: La tríada de Carney se compone por la asociación de al menos 2 de 3 tumores: tumor estromal gastrointestinal (GIST), paraganglioma extra-adrenal y condroma pulmonar. Su expresión es variable, coexistiendo en forma completa en solo el 22% de los casos. Conclusión: Los pacientes con sospecha de tríada de Carney deben recibir evaluación multidisciplinaria, estudio completo en búsqueda de tumores asociados y seguimiento a largo plazo por posibles recurrencias o metástasis.

Objective: To present a clinical case and review of the literature on the infrequent association of pulmonary and extra thoracic tumors compatible with Carney's triad. Patient and Methods: Review of clinical records of a 39 years-old female patient with history of asthma who presented in the emergency department with respiratory symptoms. An imaging study showed a pulmonary mass in the right upper lobe with the aspect of hamartoma and a mass in the left carotid artery bifurcation compatible with a possible paraganglioma. Upper gastrointestinal endoscopy showed no evidence of gastric tumor and a PET-CT (Positron Emission Tomography - Computed Tomography) excluded other lesions. Results: Patient underwent surgical resection of both tumors (pulmonary and carotid). Diagnosis of carotid paraganglioma and pulmonary hamartoma were stated by histopathology. However, lung tumor after a second pathological analysis was confirmed to be a pulmonary chondroma. Discussion: Carney's triad is defined by the association of at least 2 of 3 tumors: Gastrointestinal Stromal Tumor (GIST), extraadrenal paraganglioma and pulmonary chondroma. Its expression is variable, coexisting completely in only 22% of cases. Conclusion: Patients with suspected Carney's triad should receive a multidisciplinary assessment, a complete study searching associated tumors and long-term follow-up for recurrences or metastases.
