RESUMOObjetivo: Conhecer o manejo de pacientes com Doença de Chagas (DC) por médicos da Atenção Primária Saúde (APS) de regiões endêmicas. Método: Estudo transversal realizado com 104 médicos da APS, de 39 municípios das regiões norte de Minas Gerais e Vale do Jequitinhonha. Foram abordados perfil sociodemográfico, formação acadêmica e prática clínica através de questionário autoaplicado. Resultados: Os médicos apresentaram idade média de 33(±9,88) anos, 4(±7,26) anos de atuação na APS, 49% relataram que a graduação não ofereceu formação suficiente em DC. Embora quase 90% tinham experiência com atendimento de pacientes com DC crônica e 57% com DC aguda, apenas 9% relataram sentir-se totalmente seguros para esses atendimentos e 33% relataram não conhecer o Benzonidazol, único antitripanossômico disponível. Contribuindo para esse quadro, após a graduação somente 13,3% receberam alguma informação ou treinamento relativo à DC e quase metade recebeu esse treinamento há mais de 4 anos. Há insegurança, desconhecimento e carência de capacitações sobre DC entre profissionais médicos da APS de localidades endêmicas.
Background Chagas disease remains a major cause of cardiovascular death in endemic areas. Focused echocardiography (FoCUS) is a point-of-care means of assessing cardiac function which can be useful for the diagnosis of cardiac involvement. Objective This study aims evaluating the characteristics of validity and reliability of FoCUS applied on Chagas disease patients. Methods Patients with Chagas disease coming from an endemic area were selected from a large cohort (SaMi-Trop). A simplified echocardiogram with only three images was extracted from the conventional echocardiogram performed in this cohort. The images were evaluated by an observer who was blinded to the clinical and echocardiographic data, to determine the accuracy and reliability of FoCUS for cardiac assessment. The analysis constituted of 5 prespecified variables, dichotomized in absence or presence: left ventricular (LV) size and systolic function, right ventricular (RV) size and systolic function, and LV aneurysm. Results We included 725 patients with a mean age of 63.4 ± 12.3 years, 483 (67%) female. Abnormal electrocardiogram was observed in 81.5% of the patients. Left and right ventricular dysfunctions were found in 103 (14%) and 49 (7%) of the patients, respectively. Sensitivity, specificity, positive predictive value and negative predictive value were 84%, 94%, 70% and 97% for LV enlargement and 81%, 93%, 68% and 97% for LV systolic dysfunction, respectively, and 46%, 99%, 60% and 98% for RV dilatation, and 37%, 100%, 100% and 96% for RV dysfunction, respectively. Inter and intraobserver agreement were 61% and 87% for LV enlargement and 63% and 92% for LV dysfunction, respectively, and 50% and 49% for RV size and 46% and 79% for RV dysfunction, respectively. LV apical aneurysm was found in 45 patients (6.2%) with the lowest sensitivity of FoCUS study (11%; 95% CI 2–28%). Conclusions FoCUS showed satisfactory values of validity and reliability for assessment of cardiac chambers in patients with Chagas disease, except for apical aneurysm. This tool can identify heart disease with potential impact on patient management in the limited-resource setting.
The COVID-19 pandemic has increased the incidence of depression and other mental disorders in the general population, influenced by various individual and contextual factors. Physical activity (PA) interventions offer a promising approach to mitigating the negative mental health effects of the pandemic. This study aims to analyze the association between PA and depressive symptoms. A total of 785 individuals aged 37.4 ± 13.2 years (72.5% female) were evaluated at two different time points: the first between 2018 and 2019, and the second during the COVID-19 pandemic in 2020. Depressive symptoms, demographic, and socioeconomic data were assessed using the Beck Depression Inventory to estimate depressive symptoms. Frequency analysis and binary and multinomial regression were employed for data analysis. The prevalence of mild depressive symptoms increased from 23.1% before the pandemic to 35.1% during the pandemic. Our findings reveal that practicing PA before the pandemic was a protective factor (OR: 0.19; 95% CI: 0.13, 0.30; p < 0.001) against mild depressive symptoms. Additionally, individuals who continued to practice PA during the pandemic had a lower chance of presenting mild (OR: 0.21; 95% CI: 0.15, 0.30) and moderate/severe (OR: 0.15; 95% CI: 0.08, 0.27) symptoms. Furthermore, our study shows that PA, which was already a protective factor before the pandemic, remained protective during the pandemic, even for those with the highest levels of depression.
This study aimed to assess the prevalence of non-use of health services in the last year by people with Chagas disease (CD) in an endemic area in Brazil and the contextual and individual factors associated with this non-use. This is a multilevel study that considered contextual and individual data. Contextual data were collected from official publicly accessible databases of the Brazilian government, at the municipal level. The individual data came from the first follow-up of a Brazilian cohort that assessed patients with CD in 21 municipalities in endemic area for the disease. The sample consisted of 1,160 individuals with CD. The dependent variable “use of health services in the last year” was categorized as yes vs. no. The analysis was performed using Poisson regression with robust variance. The prevalence of non-use of health services in the last year was 23.5% (IC95%: 21.1–25.9). The contextual factor “larger population” (PR: 1.6; 95% CI = 1.2–2.0) and individual factors related to the lower severity of the disease as a functional class without limitations (PR: 1.6; 95% CI = 1.2–2.1) and unaltered N-terminal pro b-type natriuretic peptide levels (PR: 2.2; 95% CI = 1.3–3.6) increased the prevalence of non-use of the health service in the last year by people with CD. The results of this study showed that individual determinants are not isolated protagonists of the non-use of health services in the last year by people with CD, which reinforces the need for public policies that consider the contextual determinants of the use of health services by populations affected by the disease.
