Síndrome Respiratória Aguda Grave por Influenza A/B: Análise da Situação Vacinal / Severe Acute Respiratory Syndrome due to Influenza A/B: Analysis of Vaccination Status

Introdução: A Influenza é uma doença respiratória altamente contagiosa, prevenível por vacinação, afetando todos os grupos etários,com morbidade e mortalidade variáveis. O objetivo deste estudo foi analisar a relação da situação vacinal dos pacientes com Influenza A/B atendidos com Síndrome Respiratória Aguda Grave. Métodos: Estudo retrospectivo, a partir das notificações do Sistema de Informação de Agravos de Notificação Compulsório do Brasil, de pacientes com esquema vacinal conhecido para Influenza A/B em um hospital-escola do interior do Rio Grande do Sul (2012 a 2018). Resultados: Foram incluídos 596 casos de SRAG, sendo 179 (30,0%) por vírus respiratórios [92 (51,4%) Influenza A/B e 87 (48,6%) outros vírus respiratórios]. Na faixa etária de maiores de 50 anos, a frequência foi 28,2%, 6 meses a 1 ano foi de 19,6%, seguido de 13% no grupo etário de 2 a 4 anos. O esquema vacinal estava completo em 59,8% dos casos, sendo que em 37,5% dos pacientes apresentavam esquema vacinal incompleto. O tratamento antiviral foi administrado em 90,2% do pacientes com SRAG por Influenza A/B, e a alta hospitalar ocorreu em 91,3% dos casos. Conclusão: A vacinação é uma estratégia para prevenção de complicações relacionadas à Influenza. No entanto, a SRAG é uma apresentação com diagnóstico diferencial amplo, e as causas virais necessitam de confirmação para uma otimização da terapêutica antiviral. A equipe de saúde deve estar atenta a pacientes com riscos de SRAG, a fim de minimizar os desfechos negativos, mesmo nos vacinados.

Introduction: Influenza is a highly contagious respiratory disease, preventable by vaccination, affecting all age groups, with variable morbidity and mortality. The objective of this study was to analyze the relationship between the vaccination status of Influenza A/B patients seen with Severe Acute Respiratory Syndrome. Methods: Retrospective study, from notifications of the Brazilian Compulsory Notification Agencies Information System (Sistema de Informação de Agravos de Notificação Compulsório do Brasil), of patients with known vaccination schemes for Influenza A/B in a teaching hospital in the interior of Rio Grande do Sul (2012 to 2018). Results: Of the 596 cases of SARS included, 179 (30.0%) were due to respiratory viruses [92 (51.4%) Influenza A/B and 87 (48.6%) other respiratory viruses]. In the age group over 50 years, the frequency was 28.2%, from 6 months to 1 year old was 19.6%, followed by 13% in the age group of 2 to 4 years. The vaccination schedule was complete in 59.8% of cases, with 37.5% having an incomplete vaccination scheme. Antiviral treatment was administered in 90.2% of the patients with SARS by Influenza A/B, and hospital discharge occurred in 91.3% of the cases. Conclusion: Vaccination is a strategy to prevent complications related to Influenza. However, SARS is a presentation with wide differential diagnosis, and the viral causes need confirmation for an optimization of the antiviral therapy. The healthcare team must be aware of patients at risk of SARS to minimize negative outcomes, even in vaccinated patients.

Biological and socioeconomic factors as moderator in relationship between leisure-time physical activity and cardiometabolic risk in adolescents from southern Brazil

BACKGROUND@#Given the important repercussions that sociodemographic factors can have on physical activity, especially in the field of leisure, and cardiometabolic risk, it seems relevant to analyze the implications of these variables on the relationship between physical activity in leisure time (LTPA) and cardiometabolic risk. In this sense, the present study aims to verify the moderating role of biologic and socioeconomic factors in the relationship between LTPA and cardiometabolic risk in adolescents in southern Brazil.@*METHODS@#Cross-sectional study that included 1596 adolescents selected at random (58.2% girls), aged between 10 and 17 years. LTPA, biological and socioeconomic factors were assessed using a self-reported questionnaire and the cardiometabolic risk score (total cholesterol/HDL-c ratio, triglycerides, fasting glucose, systolic blood pressure, and waist circumference, considering the participant's age and sex) was included as an outcome. Associations and moderations were tested by multiple linear regression models.@*RESULTS@#It was observed a positive interaction of LTPA and sex (p = 0.048) and LTPA and school system (p = 0.037), and negative interaction of LTPA and skin color (p = 0.040), indicating that these factors were moderators in the relationship between LTPA and clustered cardiometabolic risk score (cMetS) in adolescents. A reduction in cardiometabolic risk was observed according to the increase in weekly minutes of LTPA among boys, non-white adolescents, and students from municipal schools.@*CONCLUSIONS@#The association between LTPA and cardiometabolic risk was moderated by sex, skin color, and school system in adolescents from southern Brazil.

Relationship between sleep duration and TV time with cardiometabolic risk in adolescents

OBJECTIVE@#To verify the association between sleep duration and television time with cardiometabolic risk and the moderating role of age, gender, and skin color/ethnicity in this relationship among adolescents.@*METHODS@#Cross-sectional study with 1411 adolescents (800 girls) aged 10 to 17 years. Television time, sleep duration, age, gender, and skin color/ethnicity were obtained by self-reported questionnaire. Cardiometabolic risk was evaluated using the continuous metabolic risk score, by the sum of the standard z-score values for each risk factor: high-density lipoprotein cholesterol, triglycerides, glycemia, cardiorespiratory fitness, systolic blood pressure, and waist circumference. Generalized linear regression models were used.@*RESULTS@#There was an association between television time and cardiometabolic risk (β, 0.002; 95% CI, 0.001; 0.003). Short sleep duration (β, 0.422; 95% CI, 0.012; 0.833) was positively associated with cardiometabolic risk. Additionally, age moderated the relationship between television time and cardiometabolic risk (β, - 0.009; 95% CI, - 0.002; - 0.001), suggesting that this relationship was stronger at ages 11 and 13 years (β, 0.004; 95% CI, 0.001; 0.006) compared to 13 to 15 years (β, 0.002; 95% CI, 0.001; 0.004). No association was found in older adolescents (β, 0.001; 95% CI, - 0.002; 0.002).@*CONCLUSIONS@#Television time and sleep duration are associated with cardiometabolic risk; adolescents with short sleep have higher cardiometabolic risk. In addition, age plays a moderating role in the relationship between TV time and cardiometabolic risk, indicating that in younger adolescents the relationship is stronger compared to older ones.
