ABSTRACT
OBJECTIVE: To determine the incidence of MIS-C in Brazil, describe the clinical and sociodemographic characteristics of the pediatric population affected by MIS-C and compare mortality and lethality outcomes with isolated Covid-19 and MIS-C cases. METHODS: Observational and retrospective cohort study of cases of MIS-C associated with Covid-19 in the Brazilian population between 04/01/2020 and 04/17/2021. Data from the Ministry of Health's epidemiological bulletin up to the 15th epidemiological week of 2021, were used. The analyzes were descriptive through absolute and relative frequencies. The significance level is 5% in Stata 16.0 package. RESULTS: Between 04/01/2020 and 04/07/2021, 903 cases of MIS-C associated with Covid-19 were notified in Brazil, of which, the largest part (55.26%) were male, between 0 and 4 years old (45.29%), from the Southeast region (38.76%). The deaths (61; 6.7%) were higher in the female gender, between 0 and 4 years old (47.54%) and in the Southeast region (34.43%). It was identified that the risk of death by MIS-C related to Covid-19 is 5.29 (CI = 2.83; 9.87 and P-value = <0.001) times higher in adolescents from 15-19 years old than in other age groups when compared to 0-4 years old children. Also, the residency in North region was as risk factor to death (RR = 3.72, IC = 1.29; 10.74 e P-value = 0.008). CONCLUSION: In this study, despite the numbers showing more deaths from zero to 4 years old, the risk for teenagers is notably higher. In addition, Brazil's Northern region is a risk factor that reaffirms social inequality and poor access to health.
ABSTRACT
. Social isolation is necessary during the COVID-19 pandemic but can be harmful to mental health, especially in people with neurocognitive disorders. Although physical exercise can alleviate neuropsychiatric symptoms and improve quality of life (QoL), sedentary behavior increased during the pandemic. Online interventions can contribute to improving physical activity and mental health. Objective: The objective of this study was to compare the neuropsychiatric symptoms and QoL of older adults with neurocognitive disorders who participated in an online physical exercise program with sedentary patients during the COVID-19 pandemic. Methods: In this cross-sectional study, 25 older patients with neurocognitive disorders (control group=11;online exercise group=14) were evaluated based on Neuropsychiatric Inventory (NPI) and the Quality of Life in Alzheimer's Disease (QoL-AD) scale. Results: There were differences between the two groups in the total NPI (U=36.50, p=0.025) and the nighttime behavior disturbances item (U=38.00, p=0.033), both with large effect sizes (ES=-1.03, 95% confidence interval [CI]:-1.83 to -0.16 and ES=-1.06, 95%CI -1.86 to -0.19, respectively). In terms of QoL-AD, a difference was identified only in the memory subitem (U=20.00, p=0.005), with a large ES (1.59, 95%CI 0.59-2.48). Conclusions: Older adults with neurocognitive disorders who participated in an online physical exercise program, during the COVID-19 pandemic, showed fewer neuropsychiatric total symptoms, fewer nighttime disturbances episodes, and better subjective memory, compared to their physically inactive counterparts. Randomized controlled trials should be performed to better understand the effect of physical exercise in neuropsychiatric symptoms in dementia patients during periods of social isolation.

O isolamento social é necessário na pandemia de COVID-19, mas pode impactar a saúde mental, especialmente em idosos com demência, dada a alta prevalência de sintomas neuropsiquiátricos. Apesar da prática de exercícios físicos contribuir para a redução desses sintomas e a melhora da qualidade de vida, houve um aumento de comportamento sedentário durante a pandemia. Objetivo: Comparar os sintomas neuropsiquiátricos e a qualidade de vida de idosos com distúrbios neurocognitivos que participaram de um programa de exercícios físicos online voltado a pacientes sedentários durante a pandemia de COVID-19. Métodos: Neste estudo de corte transversal, 25 idosos diagnosticados com transtorno neurocognitivo (controle=11; exercícios online=14) foram avaliados por meio do inventário neuropsiquiátrico (INP) e da escala de qualidade de vida na doença de Alzheimer (QV-DA). Resultados: Observou-se diferença entre os grupos no INP total (U=36,50, p=0,025), com tamanho de efeito grande (effect size [ES]=-1,03, intervalo de confiança - IC95% -1,83 a -0,16), e no subdomínio sono (U=38,00, p=0,033), com tamanho de efeito grande (ES=-1,06, IC95% -1,86 a -0,19), favoráveis ao grupo fisicamente ativo. Na QV-DA, houve diferença entre os grupos apenas no subitem memória (U=20,00, p=0,005), com tamanho de efeito grande (ES=1,59, IC95% 0,59 a 2,48), não houve diferença na pontuação total (U=45,5, p=0,277). Conclusões: Idosos submetidos a rotina de exercícios físicos com supervisão online na pandemia de COVID-19 apresentam menos sintomas neuropsiquiátricos, melhor qualidade de sono e memória quando comparados aos fisicamente inativos. Estudos randomizados controlados devem ser feitos para a melhor compreensão dos efeitos do exercício físico nos sintomas neuropsiquiátricos de pacientes com demência durante períodos de isolamento social.
ABSTRACT
Introduction and objectives: The cardiac sequelae of SARS-CoV-2 infection are still poorly documented. We conducted a cross-sectional study in healthcare workers to report evidence of pericardial and myocardial involvement after SARS-CoV-2 infection. Methods: We studied 139 healthcare workers with confirmed past SARS-CoV-2 infection. Participants underwent clinical assessment, electrocardiography, and laboratory tests, including immune cell profiling and cardiac magnetic resonance (CMR). Clinically suspected pericarditis was diagnosed when classic criteria were present and clinically suspected myocarditis was based on the combination of at least 2 CMR criteria. Results: Median age was 52 (41-57) years, 71.9% were women, and 16.5% were previously hospitalized for COVID-19 pneumonia. On examination (10.4 [9.3-11.0] weeks after infection-like symptoms), participants showed hemodynamic stability. Chest pain, dyspnea or palpitations were present in 41.7% participants, electrocardiographic abnormalities in 49.6%, NT-proBNP elevation in 7.9%, troponin in 0.7%, and CMR abnormalities in 60.4%. A total of 30.9% participants met criteria for either pericarditis and/or myocarditis: isolated pericarditis was diagnosed in 5.8%, myopericarditis in 7.9%, and isolated myocarditis in 17.3%. Most participants (73.2%) showed altered immune cell counts in blood, particularly decreased eosinophil (27.3%; P < .001) and increased cytotoxic T cell numbers (17.3%; P < .001). Clinically suspected pericarditis was associated (P < .005) with particularly elevated cytotoxic T cells and decreased eosinophil counts, while participants diagnosed with clinically suspected myopericarditis or myocarditis had lower (P < .05) neutrophil counts, natural killer-cells, and plasma cells. Conclusions: Pericardial and myocardial involvement with clinical stability are frequent after SARS-CoV-2 infection and are associated with specific immune cell profiles.Full English text available from:www.revespcardiol.org/en.
ABSTRACT
Introducción y objetivos: Las secuelas cardiacas tras la infección por SARS-CoV-2 todavía están poco documentadas. Se realizó un estudio transversal en trabajadores sanitarios para estudiar la prevalencia de afección pericárdica y miocárdica tras la infección por SARS-CoV-2. Métodos: Se estudió a 139 trabajadores sanitarios con infección previa por SARS-CoV-2 confirmada. Los participantes se sometieron a evaluación clínica, electrocardiograma, pruebas de laboratorio que incluyeron el perfil de células inmunitarias y resonancia magnética cardiaca (RMC). El diagnóstico clínico de pericarditis se realizó según los criterios clásicos y el diagnóstico clínico de miocarditis, ante la presencia de al menos 2 criterios en la RMC. Resultados: La mediana de edad fue 52 (intervalo, 41-57) años, el 71,9% eran mujeres y el 16,5% se había hospitalizado previamente por neumonía por COVID-19. En la evaluación (10,4 [9,3-11,0] semanas después de los síntomas de infección), todos los participantes presentaban estabilidad hemodinámica. El 41,7% tenía dolor torácico, disnea o palpitaciones;el 49,6%, alteraciones electrocardiográficas;el 7,9%, elevación de NT-proBNP;el 0,7%, elevación de troponina y el 60,4%, alteraciones en la RMC. El 30,9% de los participantes cumplían los criterios clínicos establecidos de pericarditis o miocarditis: pericarditis aislada en el 5,8%, miopericarditis en el 7,9% y miocarditis aislada en el 17,3%. La mayoría de los participantes (73,2%) mostraron recuentos alterados de células inmunitarias en sangre, en particular diminución de eosinófilos (27,3%;p < 0,001) y aumento del número de células T citotóxicas (17,3%;p < 0,001). La sospecha clínica de pericarditis se asoció (p < 0,005) particularmente con un elevado número de células T citotóxicas y recuento de eosinófilos disminuido, mientras que los participantes con sospecha clínica de miopericarditis o miocarditis tenían recuentos de neutrófilos, células natural killer y células plasmáticas más bajos (p < 0,05). Conclusiones: La afección pericárdica y miocárdica con estabilidad hemodinámica es frecuente después de la infección por SARS-CoV-2 y se asocia con perfiles de células inmunitarias específicas.
