Challenges of parents with children with intellectual and neurodevelopmental disorders during COVID-19: Experiences and their impact on mental health

Parents of children with intellectual and neurodevelopmental disorders are a highly burdened group that faces additional challenges during the COVID-19 pandemic. In this study, parents of children with intellectual and neurodevelopmental disorders (N = 600) living in Canada participated in a cross-sectional online survey. More than 96% of the parents reported facing additional challenges due to the pandemic. COVID-19-related stressors correlated with poorer mental and physical health. Parents who reported a higher amount of COVID-19-related stressors also reported more post-traumatic stress disorder (PTSD) symptoms. Resuming and implementing new services for children with intellectual and neurodevelopmental disorders and their parents will be key in alleviating the challenges for those parents.

Construction and Transcriptomic Study of Chicken IFNAR1-Knockout Cell Line Reveals the Essential Roles of Cell Growth- and Apoptosis-Related Pathways in Duck Tembusu Virus Infection.

For industrial vaccine production, overwhelming the existing antiviral innate immune response dominated by type I interferons (IFN-I) in cells would be a key factor improving the effectiveness and production cost of vaccines. In this study, we report the construction of an IFN-I receptor 1 (IFNAR1)-knockout DF-1 cell line (KO-IFNAR1), which supports much more efficient replication of the duck Tembusu virus (DTMUV), Newcastle disease virus (NDV) and gammacoronavirus infectious bronchitis virus (IBV). Transcriptomic analysis of DTMUV-infected KO-IFNAR1 cells demonstrated that DTMUV mainly activated genes and signaling pathways related to cell growth and apoptosis. Among them, JUN, MYC and NFKBIA were significantly up-regulated. Furthermore, knockdown of zinc-fingered helicase 2 (HELZ2) and interferon-α-inducible protein 6 (IFI6), the two genes up-regulated in both wild type and KO-IFNAR1 cells, significantly increased the replication of DTMUV RNA. This study paves the way for further studying the mechanism underlying the DTMUV-mediated IFN-I-independent regulation of virus replication, and meanwhile provides a potential cell resource for efficient production of cell-based avian virus vaccines.

Risk and protective factors for posttraumatic stress and posttraumatic growth in parents of children with intellectual and developmental disorders.

Background: Parents of children with intellectual and developmental disorders often experience potentially traumatic events while caring for their children. Heightened posttraumatic stress (PTS) and posttraumatic growth (PTG) have been found in this population. Objective: We aimed to explore risk and protective factors for their PTS and PTG. Method: A cross-sectional study was conducted with 385 parents (average age M = 43.14 years, SD = 7.40; 95.3% mothers). Results: Parenting trauma showed an adverse effect on developing PTS (beta = 0.25, p < .01) and a positive role in promoting PTG (beta = 0.16, p < .01). Social support was protective in its correlation with lower levels of PTS (beta = -0.12, p < .01) and higher levels of PTG (beta = 0.22, p < .01). Barriers to care were associated with increased PTS (beta = 0.23, p < .01), but unrelated to PTG (beta = .01, p = .855). Negative parenting showed a significant, but small, correlation with more severe PTS (beta = 0.11, p < .05), and was unrelated to PTG (beta = -0.09, p = .065). Conclusions: Our study increases the understanding of posttraumatic reactions in parents, predominantly mothers, of children with IDD and identified parenting-related trauma, social support, and barriers to mental health care as predictive factors of the reactions. More research is needed to confirm and validate the effects of the discussed factors. Although causation can not be inferred, prompt and adequate screening and therapeutic resources should be provided to those mothers who were exposed to multiple stressful caregiving events and had limited healthcare access and less support from their spouses, peers, and caregiving partners. HIGHLIGHTS: Parents of a child with Intellectual and Developmental Disorders with parenting trauma had higher posttraumatic stress (PTS) and posttraumatic growth (PTG).Social support was related to lower PTS and higher PTG.Barriers to care were related to higher PTS but unrelated to PTG.

Antecedentes: Los padres de niños con trastornos intelectuales y del desarrollo a menudo experimentan eventos potencialmente traumáticos mientras cuidan a sus hijos. En esta población se han encontrado un elevado estrés postraumático (PTS por sus siglas en ingles) y crecimiento postraumático (PTG por sus siglas en ingles).Objetivo: Nuestro objetivo fue explorar los factores protectores y de riesgo para PTS y PTG.Método: Se realizó un estudio transversal con 385 padres (con edad promedio M = 43,14 años, DS = 7,40; 95,3% madres).Resultados: El trauma parental mostró ser un efecto adverso en el desarrollo de PTS (beta = 0.25, p < 0.01) y un papel positivo en la promover el PTG (beta = 0.16, p < 0,01). El apoyo social fue protector en su correlación con niveles más bajos de PTS (beta = −0.12, p < .01) y niveles más altos de PTG (beta = 0.22, p < .01). Las barreras a la atención se asociaron con un aumento de PTS (beta = 0.23, p < 0.01), pero no se relacionaron con PTG (beta = 0.01, p = 0,855). La crianza negativa mostró una correlación significativa, pero pequeña, con PTS más severos (beta = 0.11, p < 0,05) y no estuvo relacionado con el PTG (beta = −0.09, p = 0.065).Conclusiones: Nuestro estudio aumenta la comprensión de las reacciones postraumáticas en los padres, predominantemente madres, de niños con IDD e identificó el trauma relacionado con la crianza, el apoyo social y las barreras para la atención de la salud mental como factores predictivos de estas reacciones. Se necesita más investigación para confirmar y validar los efectos de los factores discutidos. Si bien no se puede inferir causalidad, se deben proporcionar recursos terapéuticos y de detección, rápidos y adecuados, a aquellas madres que estuvieron expuestas a múltiples eventos estresantes del cuidado y tuvieron acceso limitado a la atención médica y menos apoyo de sus cónyuges, compañeros y cuidadores.
