2 nd Brazilian Consensus on Chagas Disease, 2015

Abstract Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research

The prognostic role of CD8+ T lymphocytes in childhood adrenocortical carcinomas compared to Ki-67, PD-1, PD-L1, and the Weiss score

Adrenocortical carcinoma (ACC) is a rare disease among children. Our goal was to identify prognostic biomarkers in 48 primary ACCs from children (2.83 ± 2.3 y; mean age ± SD) by evaluating the tumor stage and outcome for an age of diagnosis before or after 3 years, and association with ACC cluster of differentiation 8 positive (CD8+) cytotoxic T lymphocytes (CD8+-CTL) and Ki-67 immunohistochemical expression (IHC). Programmed death 1(PD-1)/Programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) in ACC was analyzed in a second, partially overlapping cohort (N = 19) with a similar mean age. All patients and control children were carriers of the germline TP53 R337H mutation. Survival without recurrence for less than 3 years and death unrelated to disease were excluded. Higher counts of CD8+-CTL were associated with patients diagnosed with ACC at a younger age and stage I, whereas a higher percentage of the Ki-67 labeling index (LI) and Weiss scores did not differentiate disease free survival (DFS) in children younger than 3 years old. No PD-1 staining was observed, whereas weakly PD-L1-positive immune cells were found in 4/19 (21%) of the ACC samples studied. A high CD8+-CTL count in ACC of surviving children is compelling evidence of an immune response against the disease. A better understanding of the options for enhancement of targets for CD8+ T cell recognition may provide insights for future pre-clinical studies

Avaliação de serviços de saúde auditiva sob a perspectiva do usuário: proposta de instrumento Hearing health service evaluation under the perspective of the users: proposal of an instrument

OBJETIVO: Verificar a aplicabilidade de um questionário de avaliação do serviço, sob a perspectiva do usuário. MÉTODOS: O questionário foi inspirado no estudo conduzido pelo Hearing and Communication Group, e apresenta 18 questões nas dimensões: acesso ao serviço, avaliação da audição, atendimento personalizado, benefício para família, comunicação e informação, e competência profissional. Cada questão foi apresentada em escala graduada de cinco pontos. A casuística foi composta por 53 pacientes (ou responsável/acompanhante), que foram convidados, pelos profissionais da recepção, a responder ao questionário. Os dados foram calculados em porcentagem e a pontuação de cada domínio e a pontuação total foi estabelecida. A estatística inferencial foi aplicada, adotando nível de significância de 5%, a fim de verificar a influência das características demográficas no escore total. RESULTADOS: O escore para o domínio acesso foi 62,25%, para avaliação da audição foi 85,96%, para atendimento personalizado foi 82,05%, para benefício para família foi 68,57%, para comunicação e informação foi 79,13%, para competência profissional foi 97,39% e para o escore total 70,65%. Verificou-se que pacientes com menor nível de escolaridade, menor tempo de atendimento no serviço e os que já receberam o AASI apresentam resultados mais elevados no escore total do questionário. CONCLUSÃO: O questionário do presente estudo mostrou-se de fácil aplicabilidade no serviço de saúde auditiva, porém, é necessária sua aplicação em serviços de saúde auditiva em nível nacional para que a padronização e os critérios de confiabilidade e validade possam ser estabelecidos.<br>PURPOSE: To verify the applicability of a questionnaire for the assessment of hearing health services, under the perspective of the users. METHODS: The questionnaire was inspired on the study conducted by the Hearing and Communication Group, and presents 18 questions focused on the following dimensions: access to the service, hearing evaluation, personal attendance, family benefits, communication and information, and professional competence. Each question of this instrument was presented in a graduation scale of five points. The casuistic comprised 53 patients (or caregiver), that were invited, by the reception professionals, to answer to the questionnaire. Data were calculated in percentage, and the score for each domain and the total score were established. Inferential statistic tests were applied, adopting a significant level of 5%, in order to verify the influences of demographic characteristics on the total score. RESULTS: The score for the access domain was 62.25%, for hearing evaluation was 85.96%, for personal attendance was 82.05%, for family benefits was 68.57%, for the domain communication and information was 79.13%, for professional competence was 97.39%, and the total score was 70.65%. It was verified that patients with lower schooling levels, lesser time attending the service, and those that had already received the hearing aid obtained higher total scores on the questionnaire. CONCLUSION: The questionnaire used in the present study proved to be easily applicable in hearing health services; however, its application on national level is necessary, so that standardization and reliability and validity can be established

Epidemiological factors related to the transmission risk of Trypanosoma cruzi in a Quilombola community, State of Mato Grosso do Sul, Brazil

INTRODUCTION: This work was an epidemiological investigation of the risk of Trypanosoma cruzi transmission in the rural Quilombola community of Furnas do Dionízio, State of Mato Grosso do Sul, Brazil. METHODS: Of the 71 animals examined, seven were captured (two opossums, Didelphis albiventris; four rats, Rattus rattus; and one nine-banded armadillo, Dasypus novemcinctus) and 64 were domestic (one canine, Canis familiaris; five pigs, Sus scrofa; two bovines, Bos taurus; five caprines, Capra sp.; and 51 ovines, Ovis aries). Parasitological tests were performed to detect parasites in the blood and to identify the morphology of flagellates. These methods included fresh examinations, buffy coat tests and blood cultures. Molecular analysis of DNA for identification of trypanosomatids was performed by polymerase chain reaction (PCR) with primers S35 and S36. RESULTS: The parasitological tests showed flagellates in an opossum and two cattle. The molecular tests showed DNA from T. cruzi in an opossum and a pig. Triatoma sordida was the only triatomine species found in the community, and it colonized households (four specimens) and the surrounding areas (124 specimens). Twenty-three specimens tested positive for flagellates, which were subsequently identified as T. cruzi by PCR. CONCLUSIONS: Data analysis demonstrated that T. cruzi has a peridomestic life cycle that involves both domestic and wild mammals

Clinical and epidemiological factors associated with spontaneous preterm birth: a multicentre cohort of low risk nulliparous women

The objective of this study was to determine incidence and risk factors associated with spontaneous preterm birth (sPTB). It was a prospective multicentre cohort study performed in five Brazilian referral maternity hospitals and enrolling nulliparous women at 19–21 weeks. Comprehensive maternal data collected during three study visits were addressed as potentially associated factors for sPTB. Bivariate and multivariate analysis estimated risk ratios. The main outcomes measures were birth before 37 weeks due to spontaneous preterm labour or premature rupture of membranes (sPTB). The comparison group was comprised of women with term births (≥37weeks). Outcome data was available for 1,165 women, 6.7% of whom had sPTB, 16% had consumed alcohol and 5% had used other illicit drugs during the first half of pregnancy. Current drinking at 19–21 weeks (RR 3.96 95% CI [1.04–15.05]) and a short cervix from 18–24 weeks (RR 4.52 95% CI [1.08–19.01]) correlated with sPTB on bivariate analysis. Increased incidence of sPTB occurred in underweight women gaining weight below quartile 1 (14.8%), obese women gaining weight above quartile 3 (14.3%), women with a short cervix (<25 mm) at 18–24 weeks (31.2%) and those with a short cervix and vaginal bleeding in the first half of pregnancy (40%). Cervical length (RRadj 4.52 95% CI [1.08–19.01]) was independently associated with sPTB. In conclusion, the incidence of sPTB increased in some maternal phenotypes, representing potential groups of interest, the focus of preventive strategies. Similarly, nulliparous women with a short cervix in the second trimester require further exploration
