ABSTRACT This study aimed to analyze the spatial pattern of natural infection index (NII) for triatomines and the risk of Chagas disease transmission in an endemic area of Northeastern Brazil. An ecological study was conducted, based on 184 municipalities in five mesoregions. The NII for triatomines was evaluated in the Pernambuco State, Brazil, from 2016 to 2018. Spatial autocorrelations were evaluated using Global Moran Index (I) and Local Moran Index (II) and were considered positive when I > 0 and p < 0.05, respectively. In total, 7,302 triatomines belonging to seven different species were detected. Triatoma brasiliensis had the highest frequency (53%; n = 3,844), followed by Triatoma pseudomaculata (25%; n = 1,828) and Panstrongylus lutzi (18.5%; n=1,366). The overall NII was 12%, and the higher NII values were P. lutzi (21%) and Panstrongylus megistus (18%). In the mesoregions of Zona da Mata, Agreste, Sertao, and Sertao do Sao Francisco, 93% of triatomines were detected indoors. The global spatial autocorrelation of I to NII was positive (0.2; p = 0.01), and II values calculated using BoxMap, MoranMap, Lisa Cluster Map were statistically significant for natural infections. With regard to the risk areas for the presence of triatomines, Zone 2 (the Agreste and Sertao regions) presented a relative risk of 3.65 compared to other areas in the state. Our study shows the potential areas of vector transmission of Chagas disease. In this study, the application of different methods of spatial analysis made it possible to locate these areas, which would not have been identified by only applying epidemiological indicators.

It is well documented that Chagas disease (CD) can pose a public health problem to countries. As one of the World Health Organization Neglected Tropical Diseases undoubtedly calls for comprehensive healthcare, transcending a restricted biomedical approach. After more than a century since their discovery, in 1909, people affected by CD are still frequently marginalised and/or neglected. The aim of this article is to tell the story of their activism, highlighting key historical experiences and successful initiatives, from 1909 to 2019. The first association was created in 1987, in the city of Recife, Brazil. So far, thirty associations have been reported on five continents. They were created as independent non-profit civil society organisations and run democratically by affected people. Among the common associations' objectives, we notably find: increase the visibility of the affected; make their voice heard; build bridges between patients, health system professionals, public health officials, policy makers and the academic and scientific communities. The International Federation of Associations of People Affected by CD - FINDECHAGAS, created in 2010 with the input of the Americas, Europe and the Western Pacific, counts as one of the main responses to the globalisation of CD. Despite all the obstacles and difficulties encountered, the Federation has thrived, grown, and matured. As a result of this mobilisation along with the support of many national and international partners, in May 2019 the 72nd World Health Assembly decided to establish World Chagas Disease Day, on 14 April. The associative movement has increased the understanding of the challenges related to the disease and breaks the silence around Chagas disease, improving surveillance, and sustaining engagement towards the United Nations 2030 agenda.

In this chapter, the main prognostic markers of Chagas heart disease are addressed, with an emphasis on the most recent findings and questions, establishing the basis for a broad discussion of recommendations and new approaches to managing Chagas cardiopathy. The main biological and genetic markers and the contribution of the electrocardiogram, echocardiogram and cardiac magnetic resonance are presented. We also discuss the most recent therapeutic proposals for heart failure, thromboembolism and arrhythmias, as well as current experience in heart transplantation in patients suffering from severe Chagas cardiomyopathy. The clinical and epidemiological challenges introduced by acute Chagas disease due to oral contamination are discussed. In addition, we highlight the importance of ageing and comorbidities in influencing the outcome of chronic Chagas heart disease. Finally, we discuss the importance of public policies, the vital role of funding agencies, universities, the scientific community and health professionals, and the application of new technologies in finding solutions for better management of Chagas heart disease.

Abstract INTRODUCTION: Chagas disease (CD) is a neglected disease caused by the parasite Trypanosoma cruzi. One-third of infected patients will develop the cardiac form, which may progress to heart failure (HF). However, the factors that determine disease progression remain unclear. Increased angiotensin II activity is a key player in the pathophysiology of HF. A functional polymorphism of the angiotensin-converting enzyme (ACE) gene is associated with plasma enzyme activity. In CD, ACE inhibitors have beneficial effects supporting the use of this treatment in chagasic cardiomyopathy. METHODS: We evaluated the association of ACE I/D polymorphism with HF, performing a case-control study encompassing 343 patients with positive serology for CD staged as non-cardiomyopathy (stage A; 100), mild (stage B1; 144), and severe (stage C; 99) forms of Chagas heart disease. For ACE I/D genotyping by PCR, groups were compared using unconditional logistic regression analysis and adjusted for nongenetic covariates: age, sex, and trypanocidal treatment. RESULTS: A marginal, but not significant (p=0.06) higher prevalence of ACE I/D polymorphism was observed in patients in stage C compared with patients in stage A. Patients in stage C (CD with HF), were compared with patients in stages A and B1 combined into one group (CD without HF); DD genotype/D carriers were prevalent in the HF patients (OR = 2; CI = 1.013.96; p = 0.04). CONCLUSIONS: Our results of this cohort study, comprising a population from the Northeast region of Brazil, suggest that ACE I/D polymorphism is more prevalent in the cardiac form of Chagas disease with HF.

Abstract Objective: To translate and culturally adapt the modified Bristol Stool Form Scale for children into Brazilian Portuguese, and to evaluate the reproducibility of the translated version. Methods: The stage of translation and cross-cultural adaptation was performed according to an internationally accepted methodology, including the translation, back-translation, and pretest application of the translated version to a sample of 74 children to evaluate the degree of understanding. The reproducibility of the translated scale was assessed by applying the final version of Brazilian Portuguese modified Bristol Stool Form Scale for children to a sample of 64 children and 25 healthcare professionals, who were asked to correlate a randomly selected description from the translated scale with the corresponding representative illustration of the stool type. Results: The final version of Brazilian Portuguese modified Bristol Stool Form Scale for children were evidently reproducible, since almost complete agreement (k > 0,8) was obtained among the translated descriptions and illustrations of the stool types, both among the children and the group of specialists. The Brazilian Portuguese modified Bristol Stool Form Scale for children was shown to be reliable in providing very similar results for the same respondents at different times and for different examiners. Conclusion: The Brazilian Portuguese modified Bristol Stool Form Scale for children is reproducible; it can be applied in clinical practice and in scientific research in Brazil.

ABSTRACT Objective: To assess the quality of life related to health for heart failure patients and to relate sociodemographic and clinical data. Method: It is an observational and transversal study, with quantitative approach, carried out in a heart failure ambulatory in the state of Pernambuco. Results: In the sample (n=101), there was prevalence of men older than 60 years old, married and professionally inactive. The quality of life related to health, based on the Minnesota Living With Heart Failure Questionnaire, was considered moderate (34.3±21.6), being significantly related to age (p=0.004), functional class (p<0.001), and patients with chagasic cardiopathy (p=0.02). Conclusion: The quality of life in the HF group of chagasic etiology was more compromised, specially in the emotional dimension. It is suggested that studies on the hypothesis that longer ambulatory follow-up improves quality of life and that having Chagas disease interferes negatively with the quality of life of heart failure patients.
RESUMEN Objetivo: Evaluar la calidad de vida relacionada con la salud de los pacientes con insuficiencia cardíaca (IC) y relacionar los datos sociodemográficos y clínicos. Método: Se trata de estudio observacional, de corte transversal, con abordaje cuantitativo realizado en Ambulatorio de insuficiencia cardíaca en el estado de Pernambuco. Resultados: En la muestra (n=101) hubo un predominio de hombres, mayores de 60 años de edad, casados y profesionalmente inactivos. La calidad de vida relacionada con la salud, desde el cuestionario Minnesota Living With Heart Failure Questionnaire, fue moderada (34,3±21,6), presentando una relación significativa con la edad (p=0,004), la clase funcional (p<0,001) y en pacientes con cardiopatía chagásica (p=0,02). Conclusión: La calidad de vida en el grupo IC de etiología chagásica estuvo más comprometida, principalmente la dimensión emocional. Se recomienda realizar estudios que aborden las hipótesis de que el mayor tiempo de seguimiento ambulatorio mejora la calidad de vida y de que tener la enfermedad de Chagas interfiere negativamente en la calidad de vida de pacientes con insuficiencia cardíaca.

Abstract Background: Chagas Disease (CD) is an important cause of morbimortality due to heart failure and malignant arrhythmias worldwide, especially in Latin America. Objective: To investigate the association of obstructive sleep apnea (OSA) with heart remodeling and cardiac arrhythmias in patients CD. Methods: Consecutive patients with CD, aged between 30 to 65 years old were enrolled. Participants underwent clinical evaluation, sleep study, 24-hour Holter monitoring, echocardiogram and ambulatory blood pressure monitoring. Results: We evaluated 135 patients [age: 56 (45-62) years; 30% men; BMI: 26 ± 4 kg/m2, Chagas cardiomyopathy: 70%]. Moderate to severe OSA (apnea-hypopnea index, AHI, ≥ 15 events/h) was present in 21% of the patients. OSA was not associated with arrhythmias in this population. As compared to patients with mild or no OSA, patients with moderate to severe OSA had higher frequency of hypertension (79% vs. 72% vs. 44%, p < 0.01) higher nocturnal systolic blood pressure: 119 ± 17 vs. 113 ± 13 vs. 110 ± 11 mmHg, p = 0.01; larger left atrial diameter [37 (33-42) vs. 35 (33-39) vs. 33 (30-36) mm, p < 0.01]; and a greater proportion of left ventricular dysfunction [LVEF < 50% (39% vs. 28% vs. 11%), p < 0.01], respectively. Predictor of left atrial dimension was Log10 (AHI) (b = 3.86, 95% CI: 1.91 to 5.81; p < 0.01). Predictors of ventricular dysfunction were AHI > 15 events/h (OR = 3.61, 95% CI: 1.31 - 9.98; p = 0.01), systolic blood pressure (OR = 1.06, 95% CI: 1.02 - 1.10; p < 0.01) and male gender (OR = 3.24, 95% CI: 1.31 - 8.01; p = 0.01). Conclusions: OSA is independently associated with atrial and ventricular remodeling in patients with CD.
Resumo Fundamento: A doença de Chagas (DC) é uma causa importante de morbimortalidade por insuficiência cardíaca e arritmias malignas em todo o mundo, especialmente na América Latina. Objetivo: Investigar a associação entre apneia obstrutiva do sono (AOS) com remodelação cardíaca e arritmias cardíacas em pacientes com DC. Métodos: Foram incluídos pacientes consecutivos com DC, com idade entre 30 e 65 anos. Os participantes foram submetidos à avaliação clínica, estudo do sono, Holter de 24 horas, ecocardiograma e monitorização ambulatorial da pressão arterial. Resultados: Foram avaliados 135 pacientes [idade: 56 (45-62) anos; 30% homens; IMC: 26 ± 4 kg/m2, cardiomiopatia chagásica: 70%]. AOS moderada a grave (índice de apneia-hipopneia, IAH, ≥ 15 eventos/h) estava presente em 21% dos pacientes. AOS não estava associada a arritmias nessa população. Em comparação com pacientes com AOS leve ou ausente, pacientes com AOS moderada a grave apresentaram maior frequência de hipertensão (79% vs. 72% vs. 44%, p < 0,01) e pressão arterial sistólica noturna mais alta: 119 ± 17 vs. 113 ± 13 vs. 110 ± 11 mmHg, p = 0,01; diâmetro do átrio esquerdo maior [37 (33‑42) vs. 35 (33-39) vs. 33 (30-36) mm, p < 0,01]; e maior proporção de disfunção ventricular esquerda [FEVE < 50% (39% vs. 28% vs. 11%), p < 0,01], respectivamente. O preditor de dimensão do átrio esquerdo foi Log10 (IAH) (β = 3,86, IC 95%: 1,91 a 5,81; p < 0,01). Os preditores de disfunção ventricular foram IAH >15 eventos/h (OR = 3,61, IC 95%: 1,31 - 9,98; p = 0,01), pressão arterial sistólica (OR = 1,06, IC95%: 1,02 - 1,10; p < 0,01) e sexo masculino (OR = 3,24, IC 95%: 1,31 - 8,01; p = 0,01). Conclusões: A AOS está independentemente associada à remodelação atrial e ventricular em pacientes com DC.

ABSTRACT Objective: to investigate spontaneous resolution rate of a series of patients with physiologic phimosis in relation to observation time and presence of symptoms. Methods: retrospective and longitudinal follow-up study of patients with physiologic phimosis, that did not apply topic treatment. These patients were invited for a new visit for reevaluation, or recent data were obtained by chart analysis. Spontaneous resolution rate was determined and statistically compared to age, presence of symptoms at first medical visit and time until reevaluation. Results: seventy one patients were included. Medium time of observation from first visit to reevaluation was 37.4 months. There was spontaneous resolution of phimosis in 32 (45%) patients. Children with spontaneous resolution were younger at initial diagnosis and were observed during a longer period of time. Most asymptomatic patients at first visit presented spontaneous resolution. However, it was not possible to stablish a significant relationship between presence of symptoms and evolution of physiologic phimosis. Conclusions: time of observation was the main determinant of spontaneous resolution of patients with physiologic phimosis, reinforcing the current more conservative approach regarding circumcision of those patients.
RESUMO Objetivo: investigar a taxa de resolução espontânea de uma série de pacientes com diagnóstico de fimose fisiológica e sua relação com o tempo de observação e com a presença de sintomas. Métodos: estudo retrospectivo e de seguimento longitudinal e observacional de pacientes em acompanhamento por fimose fisiológica, que não haviam realizado tratamento tópico. Estes pacientes foram convocados para uma consulta médica de reavaliação ou tiveram dados recentes obtidos a partir da análise dos prontuários. A taxa de resolução espontânea foi determinada e comparada estatisticamente de acordo com a idade, com a presença de sintomas no momento da primeira consulta e com o tempo transcorrido entre a primeira consulta e a reavaliação. Resultados: setenta e um pacientes foram incluídos no estudo. O tempo médio de observação, entre a primeira consulta e a reavaliação foi de 37,4 meses. Houve resolução espontânea da fimose em 32 (45%) pacientes. As crianças que apresentaram resolução espontânea eram mais jovens no momento do diagnóstico inicial e foram observadas por um maior intervalo de tempo. A maior parte dos pacientes assintomáticos na primeira consulta apresentou resolução espontânea. No entanto, não foi possível estabelecer uma relação significativa entre a presença de sintomas e a evolução da fimose fisiológica. Conclusões: o tempo de observação foi o maior determinante para a resolução espontânea de pacientes com fimose fisiológica, o que reforça a tendência atual mais conservadora em relação às indicações de circuncisão para estes pacientes.

Abstract INTRODUCTION: Elucidating the molecules involved in the inflammatory process of chronic Chagas disease may allow identification of treatment targets. METHODS: The ex vivo phenotypic expression of chemokine receptors CCR1, CCR3, CCR4, CCR5, CXCR2, CXCR3, CXCR4, and CXCR5 on the CD4+ and CD8+ T-cells of patients with chronic Chagas cardiomyopathy of varying severity was evaluated using flow cytometry. RESULTS: Differential expression of CD4+CCR3+ and CD8+CCR4+ T-cells was observed in patients with mild cardiac involvement compared, respectively, with patients with severe cardiac and asymptomatic forms of Chagas disease. CONCLUSIONS: These receptors are possibly involved in the pathogenesis of chronic Chagas cardiomyopathy.

OBJECTIVE: The present study aimed to determine from a sample of Amazonian youngsters, with normal occlusion, the mean values for soft profile characteristics using cephalometric radiographs obtained in lateral norm. METHODS: The cephalometric radiographs of the 30 youngsters, being 15 males and 15 females, with mean age of 21.6 years old, were assessed. For statistical analysis, central tendencies and dispersion measurements (mean and standard deviation) were used and, for both the comparison of the mean values of males and females and the correlations between the measurements of the soft profile and bony profile, the unpaired Student's t-test was applied. RESULTS AND CONCLUSION: After obtaining statistical data, parameters were set based on the cephalometric norms regarding the specialized literature, revealing that all variables presented a normal distribution pattern. There was sexual dimorphism for the following measurements: ANB, NAP, ANS-Me, N-ANS, Sn'-Me', and N'-SN'. Norms were determined for all the assessed measurements. Statistical differences were observed between the norm found in the present study and those found in the specialized literature.

OBJETIVO: o presente estudo teve como objetivo avaliar a idade óssea pelo método de Greulich & Pyle (1959) e o período do crescimento puberal, de acordo com o trabalho de Martins (1979). MÉTODOS: utilizaram-se radiografias de mão e punho de 201 crianças amazonenses, sendo 103 do sexo masculino e 98 do feminino, com idades cronológicas de 9 a 12 anos. Para análise estatística, utilizou-se o teste de qui-quadrado com nível de significância em 5 por cento (p<0,05). RESULTADOS E CONCLUSÕES: as crianças do sexo feminino, em relação às do sexo masculino, encontravam-se mais adiantadas em todas as fases do crescimento esquelético, para as idades estudadas, estando 50 por cento das meninas no pico do crescimento puberal, enquanto apenas 11,6 por cento dos meninos estavam na mesma fase. As idades do início e pico do surto de crescimento puberal foram mais precoces nas meninas (10,1±0,7 e 11,1±0,8 anos, respectivamente) do que nos meninos (11,4±0,7 e 12,3±0,4 anos, respectivamente). As meninas apresentaram uma maior porcentagem de maturação precoce do que os meninos (41,8 por cento e 5,8 por cento, respectivamente); enquanto a maturação tardia foi mais prevalente nos meninos (38,8 por cento) do que nas meninas (11,2 por cento). A idade óssea média dos meninos foi de 10,4±1,7 anos e das meninas, 11,7±1,8 anos, para o grupo estudado.
OBJECTIVE: This study evaluated the bone age using the Greulich & Pyle method (1959) and pubertal growth according to the study conducted by Martins (1979). METHODS: Hand and wrist radiographs of 201 children (103 boys) aged 9 to 12 years living in Amazonas were analyzed. A chi-square test was used for statistical analysis at a level of significance of 5 percent (p<0.05). RESULTS AND CONCLUSIONS: Girls were at more advanced stages in all phases of skeletal growth than boys for the ages under study; 50 percent of the girls had reached pubertal growth peak, whereas only 11.6 percent of the boys were in the same stage. The beginning and the peak of the pubertal growth spurt occurred earlier among girls (10.1 ± 0.7 and 11.1 ± 0.8 years) than among boys (11.4 ± 0.7 and 12.3 ± 0.4 years). Early maturation was more frequent among girls than among boys (41.8 percent vs. 5.8 percent), and late maturation was more prevalent among boys (38.8 percent vs. 11.2 percent). Mean bone age in the group of boys was 10.4 ± 1.7 years, and in the group of girls, 11.7 ± 1.8 years.

In 1987, the University of Pernambuco's Oswaldo Cruz Hospital in Recife, Brazil opened its Chagas Disease and Heart Failure Outpatient Clinic with the aim of providing its patients all-around care through adoption of a biopsychosocial model of care. All-around care involves caring for the patient as a whole human being in the context of the biological, psychological and social factors present, which are an inherent part of the human condition. One prerequisite for the proposed model of care is the participation of a multidisciplinary team of trained technical staff committed to this framework. Although the main focus of the service is on care, teaching and research are also an important part of its work. The Pernambuco Association of Chagas Disease Patients is guided by the same model of care and has been carrying out educational activities relating to the disease, its treatment and support for patients and family members for several years. This Association plays an important role in advocating to public authorities on behalf of patients. The accumulated experience of the past 22 years has shown us that a broad vision of health care can help clinicians and policy makers to make decisions that are more in tune with the everyday reality of the patient, which in turn has a positive impact on adherence to treatment and quality of life.
