Increases in exposure calls related to selected cleaners and disinfectants at the onset of the COVID-19 pandemic: data from Canadian poison centres. / Augmentation du nombre d'appels relatifs à une exposition à certains nettoyants et désinfectants au début de la pandémie de COVID-19 : données des centres antipoison canadiens.

Little is known about the use or misuse of cleaning products during the COVID-19 pandemic. We compiled data from January to June in 2019 and 2020 from Canadian poison centres, and report on calls regarding selected cleaning products and present year-overyear percentage change. There were 3408 (42%) calls related to bleaches; 2015 (25%) to hand sanitizers; 1667 (21%) to disinfectants; 949 (12%) to chlorine gas; and 148 (2%) to chloramine gas. An increase in calls occurred in conjunction with the onset of COVID-19, with the largest increase occurring in March. Timely access to Canadian poison centre data facilitated early communication of safety messaging for dissemination to the public.

The Canadian Surveillance System for Poison Information (CSSPI) led by Health Canada is a developing network of poison centres, health authorities and regulatory agencies that facilitates early detection of poisoning incidents and alerting at the national level to inform harm reduction interventions. In response to the COVID-19 pandemic, concerns were raised over the potential for misuse of cleaning products and disinfectants; the CSSPI network monitored and assessed these concerns. An overall increase in calls about select cleaning products and disinfectants occurred concurrently with the pandemic, with percentage increases for selected products as high as 400% compared to the same period in the previous year.

Le Système canadien de surveillance des données sur les intoxications (SCSDI), dirigé par Santé Canada, est un réseau en développement composé de centres antipoison, d'autorités sanitaires et d'organismes de réglementation, qui facilite la détection précoce des incidents d'empoisonnement et une alerte rapide au niveau national afin d'éclairer les interventions en matière de réduction des risques. En réponse à la pandémie de COVID-19, des préoccupations ayant émergé quant au risque de mauvaise utilisation de produits de nettoyage et de désinfectants, le SCSDI a surveillé et évalué ces préoccupations. Une augmentation globale du nombre d'appels concernant plusieurs produits de nettoyage et désinfectants a eu lieu en concomitance avec la pandémie, certaines augmentations pouvant atteindre jusqu'à 400 % pour certains produits par rapport à la même période de l'année précédente.

The influence of caregiver mastery on depressive symptoms.

PURPOSE: The purpose of this study was to explore how the relationship between care recipients' problem behaviors and caregivers' depressive symptoms varies as a function of caregiver mastery, controlling for the effects of caregiver age, gender, and relationship to the care recipient in caregivers of people with primary malignant brain tumor (PMBT). DESIGN: A cross-sectional design was used to gather data via telephone interviews from 95 caregivers of people with primary malignant brain tumor, recruited from 2003 to 2004 from a brain tumor treatment center, two national support groups, and a statewide cancer registry. METHODS: Measures for the study included the Neuropsychiatric Inventory-Questionnaire, Caregiver Mastery, and the Center for Epidemiologic Studies-Depression. A stepwise regression procedure was used to evaluate potential moderating and mediating relationships. FINDINGS: Data did not indicate that caregiver mastery was a moderating variable. The analysis showed caregiver mastery as a partial mediator, with both a direct effect of care recipients' problem behaviors on caregivers' depressive symptoms and an indirect effect through caregiver mastery. Concerning the indirect effect, care recipients' problem behaviors were related to lower levels of caregiver mastery, which in turn were related to more depressive symptoms in caregivers. CONCLUSIONS: Findings showed a link between care recipients' problem behaviors and caregivers' depressive symptoms, a relationship that has not been well established in oncology. This association indicates one mechanism through which problem behaviors in the care recipient might lead to caregiver depressive symptoms.

Predictors of distress in caregivers of persons with a primary malignant brain tumor.

The purpose of this cross-sectional, descriptive study was to identify predictors of distress for family caregivers of persons with a primary malignant brain tumor (PMBT). The effect of the care recipient's functional, cognitive, and neuropsychiatric status on caregiver burden and depressive symptoms was examined through telephone interviews with 95 caregivers. Care recipients' neuropsychiatric status consistently affected caregivers' depressive symptoms and burden, and assisting with activities of daily living affected burden related to caregivers' schedules and health. The care recipient's cognitive status and need for assistance with instrumental activities of daily living did not affect any outcome variable. Results may help identify caregivers at risk for negative outcomes, and suggest interventions to improve caregivers' emotional health.
