RESUMEN
OBJECTIVE: To investigate the impact of the COVID-19 pandemic on caregivers of youth with type 1 diabetes. METHODS: We performed a qualitative research based on an open-ended questionnaire that was conducted through an online platform for primary caregivers of children and adolescents with type 1 diabetes. Participants were asked to describe the impact of the COVID-19 outbreak on their caring for youth with diabetes, as well as the emotional burden that it has brought to their personal lives. Interview responses were coded and stratified by youth age: ≤ 12 years (youth aged ≤ 12 years) and between 13 and 18 years (youth aged > 12 years). The connections between the responses were identified based on either positive or negative content of the reported experience. Data were analyzed in accordance with an inductive reasoning methodology. RESULTS: A total of 318 participants (mean age of 40.3 ± 8.1 years old) were included, representing caregivers of youth aged 11.7 ± 4.3-year-old with diabetes duration of 5.1 ± 3.8 years. The preponderance of negative feelings was noteworthy. Regarding diabetes care, more than 80% of participants reported concern and anxiety about the changes in habits that accompanied the pandemic. Also, more than half of caregivers regretted the isolation of their youth, factors that were associated with greater difficulty in achieving good glycemic control. Regarding the personal burden experienced, the negative impact of uncertainties and concerns about the COVID-19 were present in almost all participants. CONCLUSION: The period of pandemic may lead to exhaustion in caregivers of youths with type 1 diabetes, which reflects the need for mental health support strategies to help those families.

BACKGROUND: Glioblastomas are the most devastating brain tumor characterized by chemoresistance development and poor prognosis. Macrophages are a component of tumor microenvironment related to glioma malignancy. The relation among inflammation, innate immunity and cancer is accepted; however, molecular and cellular mechanisms mediating this relation and chemoresistance remain unresolved. OBJECTIVE: Here we evaluated whether glioma sensitive or resistant to temozolomide (TMZ) modulate macrophage polarization and inflammatory pathways associated. The impact of glioma-macrophage crosstalk on glioma proliferation was also investigated. METHODS: GL261 glioma chemoresistance was developed by exposing cells to increasing TMZ concentrations over a period of 6months. Mouse peritoneal macrophages were exposed to glioma-conditioned medium or co-cultured directly with glioma sensitive (GL) or chemoresistant (GLTMZ). Macrophage polarization, in vitro and in vivo glioma proliferation, redox parameters, ectonucleotidase activity and ATP cytotoxicity were performed. RESULTS: GLTMZ cells were more effective than GL in induce M2-like macrophage polarization and in promote a strong immunosuppressive environment characterized by high IL-10 release and increased antioxidant potential, which may contribute to glioma chemoresistance and proliferation. Interestingly, macrophage-GLTMZ crosstalk enhanced in vitro and in vivo proliferation of chemoresistant cells, decreased ectonucleotidase activities, which was followed by increased macrophage sensitivity to ATP induced death. CONCLUSIONS: Results suggest a differential macrophage modulation by GLTMZ cells, which may favor the maintenance of immunosuppressive tumor microenvironment and glioma proliferation. GENERAL SIGNIFICANCE: The induction of immunosuppressive environment and macrophage education by chemoresistant gliomas may be important for tumor recovery after chemotherapy and could be considered to overcome chemoresistance development.
