Burden of caregivers of adult patients with schizophrenia in a predominantly African ancestry population.

PURPOSE: There is relative inattention to caregiving burden in black populations in developing economies. This study seeks to assess the level of perceived burden and social determinants of burden of care in caregivers of adult patients with schizophrenia. METHODS: In this cross-sectional study, 115 dyads of patients with schizophrenia caregivers attending public mental health clinics were consecutively recruited. Burden of care was evaluated using the 22-item Zarit Burden Scale (maximum score, 88). Multiple linear regression model explored factors associated with caregiver burden. RESULTS: Caregivers were predominantly females (75.7 %) and were on average 50.8 ± 15.0 years. Most patients with schizophrenia were males (65.2 %) and were on average 43.6 ± 17.2 years old. Caregivers showed on average, mild-to-moderate burden (score, 30.0 ± 14.7; median, 28.0). There was tendency for caregivers of patients who were parents or spouses to have higher levels of burden. In multivariable analyses, higher burden of caregiving was associated with patient's inability to perform self-care (B ± SE, 5.12 ± 1.40; p = 0.0001), closer kinship and higher numbers of psychotic episodes in previous year. The length of caregiving relationship was inversely related. CONCLUSIONS: Poorer functioning and demographic factors were important determinants of caregiver burden. Community mental health services should include self-care interventions in rehabilitation programs in Jamaica.

CPC-containing oral rinses inactivate SARS-CoV-2 variants and are active in the presence of human saliva.

Introduction. The importance of human saliva in aerosol-based transmission of SARS-CoV-2 is now widely recognized. However, little is known about the efficacy of virucidal mouthwash formulations against emergent SARS-CoV-2 variants of concern and in the presence of saliva.Hypothesis. Mouthwashes containing virucidal actives will have similar inactivation effects against multiple SARS-CoV-2 variants of concern and will retain efficacy in the presence of human saliva.Aim. To examine in vitro efficacy of mouthwash formulations to inactivate SARS-CoV-2 variants.Methodology. Inactivation of SARS-CoV-2 variants by mouthwash formulations in the presence or absence of human saliva was assayed using ASTM International Standard E1052-20 methodology.Results. Appropriately formulated mouthwashes containing 0.07 % cetylpyridinium chloride but not 0.2 % chlorhexidine completely inactivated SARS-CoV-2 (USA-WA1/2020, Alpha, Beta, Gamma, Delta) up to the limit of detection in suspension assays. Tests using USA-WA1/2020 indicates that efficacy is maintained in the presence of human saliva.Conclusions. Together these data suggest cetylpyridinium chloride-based mouthwashes are effective at inactivating SARS-CoV-2 variants. This indicates potential to reduce viral load in the oral cavity and mitigate transmission via salivary aerosols.
