Strain Differences and Effects of Environmental Manipulation on Astrocytes (Glial Fibrillary Acidic Protein), Glucocorticoid Receptor, and Microglia (Iba1) Immunoreactivity between Wistar-Kyoto and Wistar Females.

BACKGROUND: Depression is often associated with an increase in hypothalamic-pituitary-adrenal (HPA) axis reactivity and immune response. To investigate this relationship, we examined the consequences of environmental manipulation on the neural correlates of the HPA axis and immune response in an animal model of depression, the Wistar-Kyoto (WKY) rat. Additionally, female animals are often overlooked in preclinical research because of the hormone fluctuations inherent in the estrous cycle. METHODS: Female rats were randomly assigned to 1 of 3 environments for 30 days: (1) environmental enrichment (EE), (2) standard housing (SH), and (3) isolated housing (IH). Immunoreactivity of astrocytes (glial fibrillary acidic protein [GFAP]), glucocorticoid receptors (GRs), and microglia (Iba1) in the hippocampus and amygdala were measured using immunohistochemistry. RESULTS: WKY animals had significantly more GR staining area and Iba1 staining intensity and area in the CA1 of the hippocampus. In enriched Wistar rats, GFAP staining intensity and area were greater in the CA1. A trend towards a greater percent of area stained with GR was found in WKY animals as compared to that of the Wistar animals. This was due to WKY females in EE having significantly higher GR staining intensity and area in the amygdala as compared to that of animals in SH. DISCUSSION: These strain differences lend support to the use of WKY animals as an animal model of depression. Furthermore, due to the effects of EE on GFAP and GR staining in WKY females, we suggest that EE can be used as an intervention to potentially alleviate the negative effects of depression.

Cognitive Behavioral Therapy for Children With Headaches: Will an App Do the Trick?

Participants were enrolled into a pilot randomized-controlled 4-week trial comparing the efficacy and feasibility of app-based cognitive behavioral therapy (CBT) to a stretching program. Headache-related disability and quality of life were assessed using the Pediatric Migraine Disability Scale (PedMIDAS), Kidscree27, and Pediatric Quality of Life Inventory. Multivariable regression analysis were performed to assess the group effects in the presence of adherence and other covariates. Twenty participants completed the study. Adherence was significantly higher in the stretching than in the CBT app group (100% vs 54%, P < .034). When controlling for adherence and baseline scores, the stretching group showed greater reduction in PedMIDAS score (average: 29.2, P < .05) as compared to the CBT app group. However, in terms of the Quality-of-Life Indicators, pre- and postintervention raw scores were not significantly different between groups (P > .05). App-based CBT was not superior to a stretching program in reducing headache-related disability in a select population of pediatric headache patients. Future studies should assess if implementing features to the CBT app, like tailoring to pediatric age groups, would improve outcomes.

Being physically active with epilepsy: Insights from young people and their parents.

INTRODUCTION: Researchers have called for innovative tailored interventions to address specific challenges to physical activity (PA) engagement for young people with epilepsy (YPE). Working with YPE and their parents, this study aimed to identify barriers and facilitators to adoption and maintenance of PA among YPE prior to and during the COVID-19 pandemic. METHODS: Ten YPE (all female) and their 13 caregivers, and five additional caregivers to males (N = 18; 72% mothers), completed virtual focus group sessions prior to and during the COVID-19 pandemic. Trained Child Life specialists asked questions about barriers and facilitators of PA engagement experienced by YWE, which included a specific focus on the impact of epilepsy. RESULTS: Thematic analysis of the data identified both epilepsy-specific and generic themes that impact PA participation among YPE. These included: (i) epilepsy experience/impact and accommodation; (ii) safety precautions; (iii) concern about seizures; (iv) social connections and acceptance; (v) parent and family support; (vi) intrapersonal self-regulation and motivation; (vii) health benefits; and (viii) key factors in common with all youth. CONCLUSION: This study provides valuable insight into diverse social-ecological health factors that impact PA participation among YPE from two key stakeholder perspectives (YPE and their caregivers). By understanding these lived experiences, providers can better tailor individual support for YPE and their families to foster and maintain a healthy active lifestyle.
