[Adolescents' and young people's experiences of health participation during the COVID-19 pandemic in ChileExperiências de participação de adolescentes e jovens na saúde em tempos de pandemia de COVID-19 no Chile]. / Experiencias de participación en salud de adolescentes y jóvenes en tiempos de la pandemia de COVID-19 en Chile.

Objective: Shed light on the experiences and determinants of young people's and adolescents' participation in formal participation mechanisms during the SARS-CoV-2 pandemic in Chile. Methods: Cross-sectional, descriptive study with a qualitative approach, within the constructivist research paradigm. Three focus groups were conducted with key informants: young people and adolescents who regularly participate in advisory councils of Chile's Ministry of Health (MINSAL). Content analysis was applied for theoretical and emerging categories in the study. The reports were transcribed and studied with data analysis and hermeneutics. This study was conducted during the COVID-19 pandemic, between the months of March and November 2021. Results: During the pandemic, adolescents' and young people's experiences of health participation were affected; however, formal participation mechanisms such as advisory councils allowed for continuity. In this context and based on their experiences, young people and adolescents highlighted some factors that facilitated or limited their participation at three levels: individual, relational, and structural. They highlighted virtual communication, use of social networks, and digital health as excellent tools for the participation of young people and adolescents during the pandemic in Chile. Conclusion: The pandemic affected the participation mechanisms used by young people and adolescents in Chile; however, among the experiences highlighted by young people, aspects that facilitated participation emerged, such as virtual communication, digital health, and other strategies. At the same time, some gaps in health participation widened during this global health crisis, such as access mainly in rural populations.

Objetivo: Divulgar as experiências e determinantes da participação dos jovens e adolescentes em mecanismos formais de participação durante a pandemia de SARS-CoV-2 no Chile. Métodos: Estudo transversal, descritivo, com abordagem qualitativa, ligado ao paradigma construtivista de pesquisa. Foram realizados 3 grupos focais com informantes-chave: jovens e adolescentes que participam regularmente dos conselhos consultivos do Ministério da Saúde do Chile. Foi aplicada a técnica de análise de conteúdo para as categorias teóricas e emergentes do estudo. Os relatos foram transcritos e estudados com técnicas de análise de dados e hermenêutica. Este estudo foi realizado durante a pandemia de COVID-19, entre os meses de março e novembro de 2021. Resultados: Durante a pandemia, as experiências de participação de adolescentes e jovens na saúde foram afetadas, porém os mecanismos formais de participação, como os conselhos consultivos, permitiram sua continuidade. Nesse contexto, os jovens e adolescentes, em suas experiências, destacaram alguns fatores que facilitaram ou limitaram a participação, conforme três níveis de gestão: individual, relacional e estrutural. A comunicação virtual, o uso das redes sociais e a saúde digital destacaram-se como excelentes ferramentas para a participação de jovens e adolescentes em tempos de pandemia no Chile. Conclusão: A pandemia afetou os mecanismos de participação de jovens e adolescentes no Chile. No entanto, dentro das experiências destacadas pelos jovens, surgiram aspectos como comunicação virtual, saúde digital e outras estratégias que facilitaram a participação. Por outro lado, nessa crise de saúde mundial, aumentaram algumas lacunas na participação em saúde, como o acesso, principalmente em populações rurais.

[Impact of COVID-19 pandemic confinement on the behavior of children and adolescents with autism spectrum disorder]. / Impacto del confinamiento en pandemia COVID-19 en la conducta de niños, niñas y adolescentes con trastorno del espectro autista.

Coronavirus disease (COVID-19) and confinement have affected access to the health system and have impacted people's mental health, particularly families of children with autism spectrum di sorder (ASD). OBJECTIVE: To investigate the perceptions of parents of children with ASD regarding benefits, positive changes, and difficulties in behavioral management at home during the first con finement due to COVID-19 in Chile. SUBJECTS AND METHODS: We performed an exploratory cross sectional qualitative study including 118 parents of individuals with ASD aged between 2 and 15 years. An online questionnaire, prepared by a multidisciplinary committee of national experts using Delphi methodology was applied, which contains four open-ended questions related to children's behavior (difficulties, improvements, benefits, and professional support required) during the pan demic. RESULTS: Parents perceived that confinement increased emotional stress for adults and chil dren, which could exacerbate behavioral problems. The interviewees perceived improvements in child social-affective, individual autonomy, and communication skills. The family and resilience aspects, such as time-sharing that emerged during the pandemic to support children's needs, were appreciated. Parents also reported the need for professional support in behavioral and emotional management during confinement. CONCLUSION: Caregivers value the integration of the family into therapies during confinement. It is necessary to complement these results with additional studies exploring different life contexts of families with children with ASD in Chile and the impacts of long term confinement.

Descripción clínica y hallazgos polisomnográficos en tres pacientes con Síndrome de Treacher Collins / Clinical description and polysomnographic findings in three patients with Treacher Collins

El Síndrome de Treacher Collins (STC) es una enfermedad congénita del desarrollo craneofacial, siendo una complicación frecuente la obstrucción de la vía aérea. Objetivo: Describir clínicamente tres casos de STC y sus hallazgos polisomnográficos. Diseño: Estudio observacional, descriptivo y retrospectivo. Revisión de fichas clínicas y polisomnografías (PSG). Resultados: Se incluyeron tres pacientes con STC, de 1, 17 y 20 años, dos hombres. Todos presentaron malformaciones faciales compatibles con el STC. El paciente menor tuvo apneas desde el nacimiento. En las PSG, todos presentaron eficiencia del sueño disminuida e índice de microdespertares aumentado. Solo un paciente tuvo diagnóstico de Síndrome de Apnea/Hipoapnea Obstructiva del Sueño (SAHOS) severo. Conclusiones: Aún cuando las anomalías craneofaciales no difirieron entre los pacientes, hubo sólo un caso de SAHOS severo. Las otras alteraciones descritas en la PSG afectan la calidad de vida, siendo relevante la búsqueda activa de trastornos respiratorios del sueño en estos pacientes.

Treacher Collins Syndrome (STC) is a congenital craniofacial disorder, being the airway obstruction a frequent complication. Objective: To describe clinical and polysomnographic findings of three cases with STC. Methods: An observational, descriptive and retrospective study. Review of clinical records and nocturnal polysomnography was carried out. Results: Three patients with STC were included of 1, 17 and 20 years old, two were males. All of them with facial malformations compatible with STC. Only the youngest presented apneas since birth. All patients had decreased sleep efficiency and increased arousal index. Only one patient presented with severe Obstructive Sleep Apnea Syndrome (OSAS). Conclusions: Despite the fact that all the patients had similar craniofacial anomalies, only one presented with severe OSAS. The other abnormalities described in the polysomnography affect the quality of life, being relevant performing an active screening of breathing-related sleep disorders in these patients.

Regulatory T cell-like responses in deer mice persistently infected with Sin Nombre virus.

Hantavirus cardiopulmonary syndrome is a zoonotic illness associated with a systemic inflammatory immune response, capillary leak, noncardiogenic pulmonary edema, and shock in humans. Cytokines, including TNF, IFN-gamma, and lymphotoxin, are thought to contribute to its pathogenesis. In contrast, infected rodent reservoirs of hantaviruses experience few or no pathologic changes and the host rodent can remain persistently infected for life. Generally, it is unknown why such dichotomous immune responses occur between humans and reservoir hosts. Thus, we examined CD4(+) T cell responses from one such reservoir, the deer mouse (Peromyscus maniculatus), infected with Sin Nombre virus. Proliferation responses to viral nucleocapsid antigen were relatively weak in T cells isolated from deer mice, regardless of acute or persistent infection. The T cells from acutely infected deer mice synthesized a broad spectrum of cytokines, including IFN-gamma, IL-4, IL-5, and TGF-beta(1), but not TNF, lymphotoxin, or IL-17. However, in T cells from persistently infected deer mice, only TGF-beta(1) was expressed by all lines, whereas some expressed reduced levels of IFN-gamma or IL-5. The Forkhead box P3 transcription factor, a marker of some regulatory T cells, was expressed by most of these cells. Collectively, these data suggest that TGF-beta(1)-expressing regulatory T cells may play an important role in limiting immunopathology in the natural reservoir host, but this response may interfere with viral clearance. Such a response may have arisen as a mutually beneficial coadaptive evolutionary event between hantaviruses and their rodent reservoirs, so as to limit disease while also allowing the virus to persist.
