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.

Os osteomas miliares da face são caracterizados por múltiplas pápulas normocrômicas na face, afetando, geralmente, mulheres de meia idade, com história pregressa de acne. Uma paciente de 39 anos, portadora do HIV, apresentou pápulas endurecidas, com 3 anos de evolução, localizadas na região malar, glabela e mento. A microscopia óptica demonstrou formações ósseas esféricas na derme. A tomografia computadorizada da face observou pequenas calcificações na superfície, compatíveis com formação óssea. Os osteomas múltiplos da face são raros assim como sua associação com a infecção pelo HIV

Facial miliary osteoma is characterized by the presence of multiple normochromic papules, affecting mainly middle-aged women, with a previous history of acne. A 39-year-old HIV positive female patient presented hardened papules which had appeared 3 years before, located on the malar region, glabella and mentum. Optical microscopy showed spherical bone formations in the dermis. Computerized tomography of the face revealed small calcifications on the surface consistent with bone formation. Multiple facial osteomas are rare as well as its association with HIV virus infection

OBJETIVO: Os antibióticos macrolídeos podem apresentar um efeito antiinflamatório em doenças pulmonares. O objetivo deste estudo é investigar o efeito da claritromicina na resposta inflamatória celular pulmonar em camundongos Swiss. MÉTODO: Foram utilizados 8 camundongos Swiss adultos (6-8 semanas). Todos os animais receberam um desafio intranasal (80 µL) com Pseudomonas aeruginosa mortas (1 x 10(12) UFC/mL). Dois dias após o desafio, foi realizado lavado broncoalveolar (LBA) com contagem total de células (CTC) e exame citológico diferencial. O grupo em estudo (n=4) recebeu tratamento com claritromicina (50mg/kg/dia, intraperitoneal) por 5 dias, sendo iniciado o tratamento 2 dias antes do desafio intranasal. O grupo controle (n=4) não recebeu tratamento com claritromicina. RESULTADOS: Não houve diferença significativa na CTC entre os grupos (média de 2x10(6) e 1,3x10(6), respectivamente). Em ambos os grupos, houve predomínio absoluto de neutrófilos. Contudo, o grupo tratado com claritromicina, apresentou um número percentual significativamente maior de linfócitos no LBA (mediana de 2,5% vs 19%, p=0,029). CONCLUSÃO: O uso de claritromicina altera o exame citológico diferencial do lavado bronco-alveolar de camundongos Swiss com inflamação pulmonar neutrofílica, aumentando significativamente o número percentual de linfócitos.

OBJECTIVE: Macrolide antibiotics have anti-inflammatory properties in lung diseases. The aim of this study was to investigate the effect of clarithromycin in pulmonary cellular inflammatory response in mice. METHOD: Eight adult Swiss mice were studied. All animals received an intranasal challenge (80 µL) with dead Pseudomonas aeruginosa (1.0 x 10(12) CFU/mL). Bronchoalveolar lavage was performed 2 days later, with total cell count and differential cell analysis. The study group (n = 4) received clarithromycin treatment (50 mg/kg/day, intraperitoneal) for 5 days. Treatment was initiated 2 days before intranasal challenge. RESULTS: There was no significant difference in total cell count between the groups (mean: 2.0 x 10(6) and 1.3 x 10(6), respectively). In both groups, there was a predominance of neutrophils. However, the study group had a higher percentage of lymphocytes in the bronchoalveolar lavage than the control group (median of 19% vs 2.5%, P = .029). CONCLUSION: Clarithromycin alters the cytological pattern of bronchoalveolar lavage of Swiss mice with neutrophil pulmonary inflammation, significantly increasing the percentage of lymphocytes.

BACKGROUND: Several lung diseases are characterized by a predominantly neutrophilic inflammation. A better understanding of the mechanisms of action of some drugs on the airway inflammation of such diseases may bring advances to the treatment. OBJECTIVE: To develop a method to induce pulmonary neutrophilic response in mice, without active infection. METHODS: Eight adult Swiss mice were used. The study group (n = 4) received an intranasal challenge with 1 x 10(12) CFU/ml of Pseudomonas aeruginosa (Psa), frozen to death. The control group (n = 4) received an intranasal challenge with saline solution. Two days after the intranasal challenge, a bronchoalveolar lavage (BAL) was performed with total cell and differential cellularity counts. RESULTS: The total cell count was significantly higher in the group with Psa, as compared to the control group (median of 1.17 x 10(6) and 0.08 x 10(6), respectively, p = 0.029). In addition to this, an absolute predominance of neutrophils was found in the differential cellularity of the mice that had received the Psa challenge. CONCLUSIONS: The model of inducing a neutrophilic pulmonary disease using frost-dead bacteria was successfully developed. This neutrophilic inflammatory response induction model in Swiss mice lungs may be an important tool for testing the anti-inflammatory effect of some antimicrobial drugs on the inflammation of the lower airways.
