Chagas disease and perceived quality of life: a cross-sectional study

ABSTRACT Background: Chagas disease (ChD) is a neglected tropical disease that is caused by the protozoan parasite Trypanosoma cruzi and can negatively impact quality of life (QoL). This study aimed to assess and compare QoL between individuals with and without ChD. Methods: This cross-sectional study was performed within a concurrent cohort study (REDS). The participants were derived from two blood donation centers: São Paulo capital and Montes Claros, Minas Gerais, Brazil. Participants with ChD were identified in blood donations by serological diagnosis between 2008 and 2010, and those without ChD were donors with negative serology identified during the same period. QoL was assessed using the World Health Organization Quality of Life-BREF questionnaire. Logistic regression was used to compare sociodemographic and clinical characteristics between the groups, and mean, standard deviation, and beta regression were used to compare QoL. Results: In total, 611 individuals participated in the study (328 with ChD and 283 without ChD). Participants with ChD had lower QoL in the physical (p=0.02) and psychological (p<0.01) domains than did individuals without CD. Conclusions: Individuals with ChD had worse QoL perceptions. These results provide a comprehensive understanding of the impact of ChD on individuals' QoL, while also highlighting potential opportunities for improving the care and treatment of those affected.

Overview of Chagas disease surveillance in an endemic region in Southeastern Brazil

ABSTRACT Chagas disease (CD) is a neglected disease caused by the protozoan Trypanosoma cruzi. It has high morbidity and mortality rates and mainly affects socially vulnerable populations. This is a cross-sectional study, with retrospective and prospective data collection. Using questionnaires applied to environmental surveillance coordinators, we characterized the status of CD surveillance activities in municipalities endemic for the disease in Northern Minas Gerais State (MG) and Jequitinhonha Valley (Vale do Jequitinhonha). Moreover, we spatialized the vulnerability index for chronic CD in the study area. The population consisted of 22 environmental surveillance coordinators, active in 2020, from Northern MG and Jequitinhonha Valley, 21 municipalities included in the SaMi-Trop research project, and Montes Claros municipality. After applying the questionnaires to the coordinators, a descriptive analysis of the variables was performed. To characterize the active municipalities, the explanatory variables collected in the questionnaire were compared with the dichotomous variable. Bivariate descriptive analysis was performed. Finally, geoprocessing techniques were used to spatialize the data and prepare maps. Regarding the team of endemic combat agents (ECA), 90.9% reported the lack of a specific team for CD vector control actions. Of the 22 municipalities participating in this study, nine were active (41.1%). Only 25% (n=2) of active municipalities (9% of the municipalities studied) met the target of visiting 50% of households per year. Finally, 81.1% of the coordinators stated that in their municipality, they developed actions linked to primary health care (PHC). The implementation of CD surveillance activities weakened in the endemic region. Few municipalities have a surveillance team, with low regularity of active surveillance and noncompliance with the program's goal. The results suggest insufficient recording of activities in the information system, considering that there are municipalities that report performing the activities, but no production record was observed in the system.

Evaluation of the properties of WHODAS-12 measurements in individuals with Chagas disease in Brazil

ABSTRACT Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser-Meyer-Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD.

Vigilância ativa de eventos adversos pós-vacinação na atenção primária à saúde / Observación activa de eventos adversos posvacunación en la Atención Primaria de Salud / Active surveillance of adverse events following immunization in primary health care

Resumo Objetivo Descrever a vigilância ativa dos eventos adversos pós-vacinação, sua incidência e fatores associados, em um município de Minas Gerais, Brasil. Métodos Coorte prospectiva realizada na Atenção Primária à Saúde, entre 2017 e 2018. Foram acompanhados 384 indivíduos que receberam vacinas, excluindo-se aqueles que tiveram eventos adversos prévios. Na linha de base, foram coletadas informações sociodemográficas, de saúde e histórico de vacinação e, no seguimento, as características do evento adverso e das ações de vigilância epidemiológica. Estimou-se taxa de incidência de eventos adversos, e realizaram-se o teste do qui-quadrado, a regressão de Poisson e o teste de Hosmer-Lemeshow. Resultados A incidência de eventos adversos foi de 13,36 casos/100 mil doses de vacinas (intervalo de confiança de 95%: 13,34-13,38), com maior incidência em crianças menores de 5 anos. Os eventos adversos mais frequentes foram dor local, vermelhidão, endurecimento, seguidos de febre e choro persistente. Dentre os fatores associados à ocorrência dos eventos adversos, recebimento da vacina contra tétano e difteria (risco relativo: 7,9; intervalo de confiança de 95%: 2,77-12,46) e administração por meio da via intramuscular foram considerados de risco (risco relativo: 6,1; intervalo de confiança de 95%: 2,55-14,63). A conduta do profissional de enfermagem, diante das orientações sobre as vacinas recebidas, aumentou a notificação de eventos adversos (risco relativo: 3,4; intervalo de confiança de 95%: 1,53-7,68). Conclusão O estudo permitiu conhecer fatores que favorecem a ocorrência de eventos adversos. Há evidências de que condutas adotadas pelos profissionais de enfermagem nas salas de vacinação podem evitar subnotificações de eventos adversos pós-vacinação.

Resumen Observación Describir la observación activa de los eventos adversos posvacunación, su incidencia y factores asociados en un municipio del estado de Minas Gerais, Brasil. Métodos Cohorte prospectiva realizada en la Atención Primaria de Salud, entre 2017 y 2018. Se realizó el seguimiento de 384 individuos que recibieron vacunas, excluyendo a aquellos que tuvieron eventos adversos previos. En la línea basal, se recopiló información sociodemográfica, de salud e historial de vacunación y, en el seguimiento, las características del evento adverso y las acciones de observación epidemiológica. Se estimó un índice de incidencia de eventos adversos y se realizó la prueba χ2 de Pearson, la regresión de Poisson y la prueba de Hosmer-Lemeshow. Resultados La incidencia de eventos adversos fue de 13,36 casos/100.000 dosis de vacuna (intervalo de confianza de 95 %: 13,34-13,38), con mayor incidencia en niños menores de 5 años. Los eventos adversos más frecuentes fueron dolor local, enrojecimiento, endurecimiento, seguidos de fiebre y llanto persistente. Entre los factores asociados a la ocurrencia de los eventos adversos, la aplicación de la vacuna contra el tétanos y la difteria (riesgo relativo: 7,9; intervalo de confianza de 95 %: 2,77-12,46) y la administración por medio de la vía intramuscular fueron considerados de riesgo (riesgo relativo: 6,1; intervalo de confianza de 95 %: 2,55-14,63). La conducta del profesional de enfermería ante las instrucciones sobre las vacunas recibidas aumentó la notificación de eventos adversos (riesgo relativo: 3,4; intervalo de confianza de 95 %: 1,53-7,68). Conclusión El estudio permitió conocer factores que favorecen a la ocurrencia de eventos adversos. Hay evidencias de que las conductas adoptadas por los profesionales de enfermería en las salas de vacunación pueden evitar subnotificaciones de eventos adversos posvacunación.

Abstract Objective To describe the active surveillance of adverse events following immunization, their incidence and associated factors in a municipality of Minas Gerais, Brazil. Methods This is a prospective cohort conducted in Primary Health Care between 2017 and 2018. A total of 384 individuals who received vaccines were followed up, excluding those who had previous adverse events. At baseline, sociodemographic, health and vaccination history information and, in follow-up, the characteristics of adverse events and epidemiological surveillance actions were collected. The incidence rate of adverse events was estimated, and the chi-square test, poisson regression and Hosmer-Lemeshow test were performed. Results The incidence of adverse events was 13.36 cases/100,000 doses of vaccines (95% confidence interval: 13.34-13.38), with a higher incidence in children under 5 years of age. The most frequent adverse events were local pain, redness, hardening, followed by fever and persistent crying. Among the factors associated with the occurrence of adverse events, receiving tetanus and diffrhyphria vaccine (relative risk: 7.9; 95% confidence interval: 2.77-12.46) and intramuscular administration were considered at risk (relative risk: 6.1; 95% confidence interval: 2.55-14.63). Nursing professionals' conduct, considering the guidelines on the vaccines received, increased adverse event reporting (relative risk: 3.4; 95% confidence interval: 1.53-7.68). Conclusion The study allowed to know factors that favor the occurrence of adverse events. There is evidence that conducts adopted by nursing professionals in immunization rooms may avoid underreporting of adverse events following immunization.
