Buscou-se avaliar a frequência de ansiedade e depressão e seus fatores associados ao longo da pandemia de COVID-19. Estudo transversal exploratório envolvendo 1.057 participantes, sendo aplicados os questionários GAD-7 e PHQ-9, através de Plataforma Google Forms, com amostragem bola de neve. A média de idade foi de 38 ± 14 anos, sendo 78% mulheres, provindos de 21 Estados brasileiros. Quarenta e dois por cento dos participantes tiveram escore GAD-7 ≥ 10, cerca de 53% teve escore PHQ-9 ≥ 10. Principais fatores de risco incluíram: gênero feminino, ser jovem, casado ou com companheiro, consumir bebidas alcoólicas, problemas psiquiátricos prévios, utilizar medicação para dormir, dormir menos de 8 horas, percepção negativa sobre COVID-19, estar em isolamento social, pesadelos frequentes e ideação suicida. O Brasil mantém-se com altos níveis de ansiedade e depressão durante a pandemia em associação com ideação suicida.

Anxiety and depression disorders are associated with professional and academic impairment and reduced life quality. Frequency of symptoms of anxiety and depression, and their association with health risk behaviors during the COVID-19 pandemic are evaluated. Cross-sectional study comprised 1,057 participants, 78% females, mean age 38±14 years, from 21 different Brazilian states. GAD-7 and PHQ-9 inventories were applied by Google Forms, with snowball sampling. Forty-two percent of the participants had a GAD-7 score ≥ 10, while 53% had a PHQ-9 score ≥ 10. Main risk factors comprised: being female, young, married or with partner, consuming alcoholic beverages, having previous psychiatric problems, taking sleeping pills, sleeping less than 8 hours, having a negative perception about COVID-19, staying isolated, having frequent nightmares and suicide thoughts. Brazil is a country featuring high levels of symptoms of anxiety and depression, significantly associated with suicide thoughts.

Association between Clinical Risk Score (Heart, Grace and TIMI) and Angiographic Complexity in Acute Coronary Syndrome without ST Segment Elevation. / Associação entre Escores de Risco Clínico (HEART, GRACE e TIMI) e Complexidade Angiográfica na Síndrome Coronária Aguda sem Elevação do Segmento ST.

BACKGROUND: GRACE, TIMI and HEART scores have been previously validated to predict serious untoward events among patients with non-ST elevation acute coronary syndrome (Non-ST ACS). However, the ability of these scores to discriminate the angiographic complexity of coronary artery disease has not been clearly established. OBJECTIVES: We sought to evaluate the correlation between clinical scores (TIMI, GRACE and HEART) and the anatomical complexity assessed by SYNTAX score, among non-ST ACS patients undergoing cinecoronariography. METHODS: Transversal cohort encompassing patients with diagnosis of Non-ST ACS referred to invasive stratification in our single center, between July 2018 and February 2019. Association between the scores was established by the Pearson's linear correlation test while the accuracy of the clinical scores versus SYNTAX score was determined with the ROC curve. RESULTS: A total of 138 patients were enrolled. Median GRACE, TIMI and HEART scores were 97, 3 and 5, respectively, whereas the median SYNTAX was 8. There was a positive correlation between the SYNTAX and the HEART (ρ =0.29; p<0.01) and GRACE (ρ =0.18; p<0.01) scores, but the correlation with TIMI reached no statistical significance (ρ =0.15; p=0.08). The HEART score was also the one with the highest area under the curve to predict a SYNTAX ≥32 [HEART = 0.81 (IC95% 0.7-0.91). HEART> 4 presented 100% sensitivity, with 50% specificity; and GRACE> 139 showed 55% sensitivity and 97% specificity for high SYNTAX. CONCLUSION: The clinical scores presented a positive, although modest, association with the SYNTAX score. The combined use of HEART and GRACE offers good accuracy for detecting angiographic complexity.

FUNDAMENTOS: Os escores GRACE, TIMI e HEART foram validados para avaliar desfechos clínicos desfavoráveis no contexto da suspeita de síndrome coronária aguda sem elevação do segmento ST (SCASSST). No entanto, a associação entre os escores clínicos e a complexidade angiográfica ainda não está bem estabelecida. OBJETIVOS: Descrever as características clínicas de pacientes com SCASSST admitidos em internação hospitalar para estratificação invasiva, a fim de avaliar a associação entre os escores clínicos (TIMI, GRACE e HEART) e a complexidade angiográfica, através do escore SYNTAX. MÉTODOS: Estudo observacional incluindo pacientes com diagnóstico de SCA e admitidos no Instituto Dante Pazzanese de Cardiologia entre os meses de julho de 2018 e fevereiro de 2019. A associação entre os escores foi avaliada por correlações bivariadas e a sua acurácia pela área sob a curva (ASC) ROC. A significância estatística foi estabelecida em 5% (p < 0,05). RESULTADOS: Um total de 138 pacientes foram diagnosticados com SCASSST. As medianas do GRACE, TIMI e HEART foram de 97, 3 e 5, respectivamente. A mediana do SYNTAX foi de 8. Foram observadas correlações positivas do SYNTAX com o HEART (ρ = 0,29; p < 0,01) e o GRACE (ρ = 0,18; p < 0,03). Em contrapartida, a correlação com o TIMI não atingiu significância estatística (ρ = 0,15; p = 0,08). O HEART foi o escore com a maior ASC para predizer SYNTAX > 32 [HEART = 0,81] (IC 95% 0,7-0,91). HEART > 4 apresentou sensibilidade de 100%, com especificidade de 50%, e GRACE > 139 sensibilidade de 55% e especificidade de 97% para SYNTAX alto. CONCLUSÃO: Os escores clínicos de risco apresentam associação modesta ao escore SYNTAX. O uso combinado do HEART e do GRACE, entretanto, oferece acurácia favorável para a detecção de complexidade angiográfica.

Mental Violence: The COVID-19 Nightmare.

The year 2020 has generated profound changes in personal and working relations, and in dreams of millions of people worldwide. The aim of this study was to investigate the frequency and content of nightmares during the COVID-19 pandemic in Brazil, evaluating its associations with sociodemographic, occupational, and clinical factors. Cross-sectional exploratory study, including 1,057 participants who responded to an online survey about mental violence and nightmares during the pandemic, between May 25 and June 1, 2020. A descriptive analysis of the results was done to obtain frequency tables. McNemar's non-parametric test was used to compare the frequency of nightmares before and after the pandemic, and logistic regression models, to identify factors most strongly associated with the pandemic nightmares. Participants were from 21 Brazilian states, with a mean age of 38 ± 14 years, and 78% women. Half of them (n = 529) reported at least one nightmare episode during the pandemic, and 32.9% (n = 348) described a pandemic content. There was nearly a 3-fold increase in the occurrence of nightmares "once a week or more" during the pandemic, 9% before vs. 25% after. Prior psychiatric care, suicidal ideation, sleep medication, increased pandemic alcohol consumption, perceiving high risk of contamination, being woman, and of younger age were factors associated with having nightmares during the pandemic. Prior psychiatric care, sleep medication, and age remained significant after excluding participants without nightmares and comparing between individuals with and without a pandemic content. We conclude the COVID-19 pandemic has affected people's dreams. The increase in the frequency of nightmares, their pandemic content, and association with previous conditions are a concerning public mental health issue and should be taken into consideration by authorities and policy makers.

Sleep Apnea and Nocturnal Cardiac Arrhythmia: A Populational Study / Apneia do Sono e Arritmia Cardíaca Noturna: Estudo Populacional

Background: The mechanisms associated with the cardiovascular consequences of obstructive sleep apnea include abrupt changes in autonomic tone, which can trigger cardiac arrhythmias. The authors hypothesized that nocturnal cardiac arrhythmia occurs more frequently in patients with obstructive sleep apnea. Objective: To analyze the relationship between obstructive sleep apnea and abnormal heart rhythm during sleep in a population sample. Methods: Cross-sectional study with 1,101 volunteers, who form a representative sample of the city of São Paulo. The overnight polysomnography was performed using an EMBLA® S7000 digital system during the regular sleep schedule of the individual. The electrocardiogram channel was extracted, duplicated, and then analyzed using a Holter (Cardio Smart®) system. Results: A total of 767 participants (461 men) with a mean age of 42.00 ± 0.53 years, were included in the analysis. At least one type of nocturnal cardiac rhythm disturbance (atrial/ventricular arrhythmia or beat) was observed in 62.7% of the sample. The occurrence of nocturnal cardiac arrhythmias was more frequent with increased disease severity. Rhythm disturbance was observed in 53.3% of the sample without breathing sleep disorders, whereas 92.3% of patients with severe obstructive sleep apnea showed cardiac arrhythmia. Isolated atrial and ventricular ectopy was more frequent in patients with moderate/severe obstructive sleep apnea when compared to controls (p < 0.001). After controlling for potential confounding factors, age, sex and apnea-hypopnea index were associated with nocturnal cardiac arrhythmia. Conclusion: Nocturnal cardiac arrhythmia occurs more frequently in patients with obstructive sleep apnea and the prevalence increases with disease severity. Age, sex, and the Apnea-hypopnea index were predictors of arrhythmia in this sample. .

Fundamento: Os mecanismos relacionados às consequências cardiovasculares da apneia obstrutiva do sono incluem modificações abruptas no tônus autonômico, que podem desencadear arritmias cardíacas. Os autores tiveram como hipótese a ocorrência de arritmias cardíacas noturnas maiores em pacientes portadores de apneia obstrutiva do sono. Objetivo: Analisar a relação entre a apneia obstrutiva do sono e o registro de anormalidade no ritmo cardíaco, durante o sono, em uma amostra populacional. Métodos: Estudo transversal com uma amostra representativa da cidade de São Paulo de 1.101 voluntários. A polissonografia de noite inteira foi realizada por meio de um sistema digital (EMBLA® S7000), durante o horário regular de sono do indivíduo. O canal de eletrocardiograma foi extraído, duplicado e, em seguida, analisado com um sistema Holter (Cardio Smart®). Resultados: Um total de 767 participantes, sendo 461 do sexo masculino, com idade média de 42,00 ± 0,53 anos, foi incluído nas análises. Pelo menos um tipo de distúrbio do ritmo cardíaco noturno (arritmia atrial/ventricular ou pausa) foi observado em 62,7% da amostra. A ocorrência de arritmias cardíacas noturnas foi mais frequente com o aumento da gravidade da doença. A perturbação do ritmo foi observada em 53,3% da amostra sem distúrbios respiratórios do sono, enquanto que 92,3% dos pacientes com grave apneia obstrutiva do sono apresentaram arritmia cardíaca. Ectopia atrial e ventricular isolada foi mais frequente em pacientes com apneia obstrutiva do sono moderada/severa quando comparada com controles (p < 0,001). Após controle de potenciais fatores de confusão, idade, sexo e Índice de Apneia-Hipopneia foram associados à arritmia cardíaca noturna. Conclusão: Arritmias cardíacas ...
