In-school fighting often results in severe punishment and compromised learning outcomes, without adequate consideration of contextual factors or student vulnerabilities. In this study, using a large, nationally representative data sample from the 2019 Youth Risk Behavior Survey ( N = 13677), we assessed associations between a history of bullying victimization (at school and online) and past year fighting at school among U.S. high school students. Multiple regression models were used, adjusting first for demographics, and then for demographics and emotional-behavioral risks (depressive symptoms, alcohol consumption, and sexual violence victimization), for the total sample and then stratified by gender/sex. Both cyberbullying and in-school bullying were significantly associated with past year in-school fighting for the total sample, with associations retained, but marginally attenuated in fully adjusted models (cyberbullying: AOR: 1.30; 95% CI: 1.01–1.66 and in-school bullying: AOR: 1.96, 95% CI: 1.57–2.45). Gender/sex-stratified models demonstrated retained associations for males (cyberbullying: AOR: 1.93; 1.51–2.46 and in-school bullying: AOR: 2.70, 95% CI: 2.18–3.34) and females (cyberbullying: AOR: 1.89; 1.33–2.68 and in-school bullying: AOR: 1.66, 95% CI: 1.19–2.33) after adjusting for demographics, but only for males after adjusting for demographics and emotional-behavior risk factors (cyberbullying: AOR: 1.43; 95% CI: 1.07–1.93 and in-school bullying: AOR: 2.25; 95% CI: 1.73–2.92). These results demonstrate a significant association between bullying victimization and fighting, which was amplified for male students, and partially explained by social and emotional risks. This suggests that punitive approaches to fighting in school may be resulting in compounded harms for already vulnerable adolescents and that support-oriented approaches emphasizing conflict resolution, social-emotional well-being, positive gender identity development, and bullying prevention may be more appropriate.

Many expect upward trends in online college course enrollment to continue. Despite perceived improvements in online pedagogical practice and advantages afforded by virtual platforms, most students and professors still perceive social interaction, engagement, and overall learning to be more challenging online than in person. More than 3 in 10 college students are less willing to participate in discussions online compared to in person. More than 7 in 10 professors report needing help with strategies for keeping students engaged online. As such, we must identify strategies that cater to students’ academic, and social-emotional needs in an online environment. Breakout rooms have often been implemented to promote discussion and collaboration, however, when not well-structured, they often increase social discomfort instead. In this mixed methods study, using surveys, interviews and class observations, we examine student-led talking circles in an undergraduate adolescent development course ( N = 61), in which student discussion leaders prepared questions and facilitated small group conversations using structured turn-taking protocols. Nearly 95% of students felt talking circles increased peer connectedness, 92% felt they improved content learning, and 90% felt they increased engagement. Students largely attributed these benefits to specific elements of the talking circle format. Regression results revealed significant associations between peer connectedness and perceived academic benefit, after accounting for demographics, basic psychological needs, dispositional factors, and norms of communication.

La artritis reumatoide (AR) es una enfermedad de carácter autoinmune, que suele asociarse a la presencia de autoanticuerpos; pese a décadas de estudio, su etiología aún no está clara. En la actualidad, la investigación en torno a la AR está muy influenciada por el campo de la epigenética, con lo cual se han podido establecer asociaciones prometedoras, pudiéndose señalar que las modificaciones epigenéticas juegan un papel importante en la patogenia de la AR. En este sentido, se hace necesario ampliar el conocimiento acerca de las estas modificaciones en la AR, considerando que pueden ofrecer un mayor entendimiento de la fisiopatología de la enfermedad influenciando positivamente en prevención, diagnóstico y nuevas dianas terapéuticas. Con el propósito de profundizar en las modificaciones epigenéticas de la AR se consultaron distintas fuentes bibliográficas de base científica, seleccionando los artículos más relevantes  y con amplia evidencia respecto al tema.
