ABSTRACT
OBJECTIVES: This study aimed to evaluate the association between the sociodemographic characteristics of caregivers and patients with stroke, clinical data on stroke, and disability with caregiver burden, hopelessness, and anxiety. MATERIALS AND METHODS: This cross-sectional study included patients with stroke of either sex, aged >18 years. Data were collected between January 2020 and July 2021. Patient demographic included age, sex, stroke type, severity, etiology, topography, treatment, and stroke recurrence. Stroke disability was assessed using the modified Rankin Scale and Barthel Index at 90 days post-discharge. Additionally, caregiver burden, hopelessness, and anxiety were evaluated during patient consultations using the Zarit Burden Interview (ZBI), Beck Hopelessness Scale (BHS), and Beck Anxiety Inventory (BAI). RESULTS: We included 104 patients with stroke and their caregivers. Overall caregiver burden was moderate (ZBI: 24 [25]), with mild hopelessness (BHS: 4 [4]) and minimal to mild anxiety (BAI: 8 [13]). The linear regression model presented in Table 3 showed that female caregivers scored up to 11 points higher on the Zarit Burden Interview (p = 0.011). Additionally, increased patient age was associated with a higher caregiver burden (p = 0.002) on the Zarit Burden Interview. Posterior circulation stroke and total anterior circulation stroke were also associated with higher Zarit Burden Interview scores compared to lacunar stroke (p = 0.017). Age was not associated with caregiver burden in the entire sample. However, an association between age and caregiver burden was found only in the female group. Furthermore, women aged 65 years and older experienced a more severe burden than women aged 18 to 64 years (p<0.001). Stroke disability was not associated with caregiver burden. CONCLUSIONS: Older female caregivers were significantly affected when caring for stroke patients. Total anterior circulation stroke and Posterior circulation stroke increased Zarit Burden Interview scores. However, no association was observed between stroke disability and the caregiver burden.
ABSTRACT
Neurocysticercosis is a heterogeneous disease, and the patient's sex seems to play a role in this heterogeneity. Hosts' sexual dimorphism in cysticercosis has been largely explored in the murine model of intraperitoneal Taenia crassiceps cysticercosis. In this study, we investigated the sexual dimorphism of inflammatory responses in a rat model of extraparenchymal neurocysticercosis caused by T. crassiceps. T. crassiceps cysticerci were inoculated in the subarachnoid space of Wistar rats (25 females, 22 males). Ninety days later, the rats were euthanized for histologic, immunohistochemistry, and cytokines studies. Ten animals also underwent a 7-T magnetic resonance imaging (MRI). Female rats presented a higher concentration of immune cells in the arachnoid-brain interface, reactive astrogliosis in the periventricular region, in situ pro-inflammatory cytokine (interleukin [IL]-6) and anti-inflammatory cytokine (IL-10), and more intense hydrocephalus on MRI than males. Intracranial hypertension signals were not observed during the observational period. Overall, these results suggest sexual dimorphism in the intracranial inflammatory response that accompanied T. crassiceps extraparenchymal neurocysticercosis.
