Depression and suicide risk during the Covid-19 pandemic at a Brazilian public health psychosocial addiction care center: a preliminary report

Abstract Objective To evaluate the impact of the Covid-19 pandemic on depressive symptoms and suicide risk among patients receiving treatment at a Public Health Psychosocial Addiction Care Center (CAPS AD III) in Porto Alegre, Brazil. Methods Questions from the Coronavirus Health Impact Survey (CRISIS) translated into Brazilian Portuguese were used to evaluate 70 patients' perceptions of and behaviors during the Covid-19 pandemic. Validated Brazilian versions of the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder-7 (GAD-7) were used to evaluate the severity of depressive symptoms, suicide risk, and anxiety symptoms. A multiple logistic regression model was used to evaluate predictors of suicide risk in the sample. Results Around 70% of patients reported moderate depressive symptoms and 30% reported severe depressive symptoms, 17% of patients reported having thoughts of suicide or death on more than half of days and 10% reported having them daily. The logistic regression model identified history of alcohol use as the main predictor of suicide risk in (OR 13.0, p = 0.03). Conclusions Individuals with a history of alcohol consumption had significantly higher suicide risk scores at a psychosocial public health care center in Brazil during the Covid-19 pandemic. This result may be important for devising better strategies and interventions to support this specific population profile.

Especificidad frente a estreptococos grupo A, C y G de la prueba de "CAMP reversa" en identificación de Clostridium perfrigens / Specificity of the reverse CAMP test with Streptococcus groups A, C and G for the identification of Clostridium perfringens

Se estudió la especifidad de la prueba de "CAMP reversa" para la identificación de Clostridium perfringens en relación a la posible existencia de reacciones cruzadas frente a estreptococos grupos A, C y G. Noventa y ocho cepas de Clostridium se enfrentaron a 10 cepas de S. agalactiae, 10 cepas de S. pyogenes, 2 cepas de Streptococcus grupo C y 1 del grupo G. Todas las cepas de S. agalactiae ensayadas permitieron poner de manifiesto una reacción de "CAMP reversa" positiva al enfrentarlas a cepas de C. perfringens. No se observaron reacciones cruzadas de C. perfringens frente a los Streptococcus de los grupos A, C y G probados. La prueba de "CAMP reversa" fue específica para todas las cepas de C. perfringens ensayadas
