Oral health of an indigenous population in northeastern Brazil: a cross-sectional Study of the Fulni-ô ethnic group

ABSTRACT BACKGROUND: There is a lack of studies evaluating the oral health of traditional indigenous communities in Brazil. OBJECTIVES: Thus, the objective of this study was to describe the oral health characteristics of the indigenous Fulni-ô ethnic group in Northeast Brazil. DESIGN AND SETTING: A cross-sectional observational investigation was conducted within the Project on Atherosclerosis among Indigenous Populations. METHODS: This study included participants of both sexes from the Fulni-ô ethnic group. The participants included in this investigation underwent a comprehensive oral health evaluation by a registered and experienced dentist to assess oral health and identify potentially malignant oral lesions. Participants with suspicious lesions were referred for biopsy. Shapiro-Wilk, Mann-Whitney, and Student's t-tests were used, and measures of central tendency and dispersion were described. Statistical significance was 5%. RESULTS: A total of 104 individuals were included in this study. The prevalence of the use of tobacco derivatives was 94.0%, with similarities between sexes. The prevalence of oral changes in this study population was 84.4%. Fifty-one individuals who underwent oral reassessment were referred for oral lesion biopsy. CONCLUSIONS: This study demonstrated a high prevalence of oral alterations in the Fulni-ô population. Histopathological analyses indicated the presence of mild oral epithelial dysplasia in five cases.

Awareness of stroke among patients with chronic kidney disease on hemodialysis: a cross-sectional study

ABSTRACT BACKGROUND: Stroke is a major cause of mortality worldwide. Renal dysfunction is an important risk factor for stroke. Brazilian studies on stroke knowledge are generally population based. Studies stratifying stroke knowledge according to comorbidities are rare. Scientific data are essential to guide the awareness of stroke. OBJECTIVE: To assess stroke knowledge in patients with chronic kidney disease (CKD) on hemodialysis. DESIGN AND SETTING: Cross-sectional analytical study of patients with CKD on hemodialysis in north-eastern Brazil. METHODS: A self-administered questionnaire survey on stroke awareness was administered to patients with CKD on hemodialysis between April and November 2022. The chi-square test and other descriptive statistics were used. Univariate and multivariate analyses were performed using logistic regression. RESULTS: A total of 197 patients were included in the analysis. The Brazilian acronym for stroke was used by 53.5% of the participants. Less than 10.0% of the sample showed optimal decision-making ability regarding stroke. Of the participants, 29.9% knew at least one risk factor and one symptom; however, this was considered as having below the minimum capacity because they did not know the emergency service call number. In the analysis adjusted for income and education, females (odds ratio [OR], 0.40%; 95% confidence interval [CI], 0.20-0.82), older patients (OR, 0.24%; 95% CI, 0.09-0.63) and having at most one comorbidity (OR, 0.48%; 95% CI, 0.23-0.98) were factors for lower levels of knowledge or ideal decision-making capacity against stroke. CONCLUSIONS: Patients on hemodialysis, especially women and older people, have little knowledge about stroke.

Urbanization and kidney dysfunction in Brazilian indigenous people: a burden for the youth

SUMMARY OBJECTIVE: The aim of this study was to investigate whether the degree of urbanization influences the prevalence of chronic kidney disease in Brazilian indigenous people. METHODS: This is a cross-sectional study conducted between 2016 and 2017 in northeastern Brazil and includes individuals aged between 30 and 70 years from two specific indigenous groups who volunteered to participate in the study: the Fulni-ô people (lowest degree of urbanization) and the Truká group (greater degree of urbanization). Cultural and geographical parameters were used to characterize and measure the magnitude of urbanization. We excluded individuals with known cardiovascular disease or renal failure who required hemodialysis. Chronic kidney disease was defined as a single measurement of an estimated glomerular filtration rate <60 mL/min/1.73 m2 using the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. RESULTS: A total of 184 indigenous people from the Fulni-ô group and 96 from the Truká group with a median age of 46 years (interquartile range: 15.2) were included. We found a chronic kidney disease rate of 4.3% in the total indigenous population, generally affecting an older population: 41.7% over 60 years old (p<0.001). The Truká people had a chronic kidney disease prevalence of 6.2%, with no differences in kidney dysfunction across age groups. The Fulni-ô participants had a chronic kidney disease prevalence of 3.3%, with a higher proportion of kidney dysfunction in older participants (of the six Fulni-ô indigenous people with chronic kidney disease, five were older). CONCLUSION: Our results suggest that a higher degree of urbanization seems to negatively influence the prevalence of chronic kidney disease in Brazilian indigenous people.

Awareness towards stroke among high school students in Brazil: a cross-sectional study

ABSTRACT BACKGROUND: Stroke is one of the main causes of death worldwide. Educational interventions on stroke are potentially effective in reducing the period between the onset of symptoms and the initial emergency medical assistance. OBJECTIVES: To assess high school students' knowledge of stroke. DESIGN AND SETTING: Cross-sectional study conducted in high schools in northeastern Brazil. METHODS: A self-structured questionnaire survey regarding stroke awareness was applied among high school students in northeastern Brazil. Data were collected between 2018 and 2019. The chi-square test and other descriptive statistics were used. Univariate and multivariate analyses were performed using logistic regression. RESULTS: A total of 1,788 students were analyzed. Eighty percent (n = 1430) of them did not have the minimum knowledge on how to act in a stroke situation. Only 10% (n = 179) presented the ideal knowledge on how to act. Males presented lower levels of knowledge on risk factors (odds ratio, OR: 0.62%; 95% confidence interval, CI: 0.49-0.79) and signs and symptoms of stroke (OR: 0.63%; 95% CI: 0.52-0.77). Students with ≥ 10 years of schooling (OR: 1.64%; 95% CI: 1.30-2.07) demonstrated greater knowledge of signs and symptoms of stroke. Students aged 18 years (OR: 1.70%; 95% CI: 1.14-2.52) demonstrated greater knowledge than other ages regarding the telephone number of the emergency medical services. CONCLUSIONS: There was a knowledge deficit with regard to recognizing stroke and activating the emergency medical services. The findings apply to the sample investigated and suggest that there is a need for stroke educational interventions, starting in high school.

Programa Mais Médicos e as comunidades indígenas do Norte da Bahia: relato de experiência / The Mais Médicos Program and the indigenous communities of Northern Bahia: experience report / Programa Más Médicos y las comunidades indígenas del Norte de Bahía: reporte de experiencia

As ações para construção de um modelo de prestação de serviços de saúde para a população indígena só foram intensificadas em 2002, quando foi criada a Política Nacional de Saúde dos Povos Indígenas. Dessa forma, ocorreu a utilização de profissionais oriundos do Projeto Mais Médicos nos Distritos Sanitários Especiais Indígenas. Assim, este trabalho descreve a experiência de profissionais do Projeto Mais Médicos para o Brasil em comunidades indígenas do norte da Bahia, no polo de Paulo Afonso. Essas comunidades se caracterizam por baixas condições socioeconômicas de maneira geral e os povos indígenas do sertão do nordeste brasileiro são amplamente afetados pelo processo de urbanização. Durante o programa, foi possível perceber que as comunidades indígenas já trazem consigo os efeitos psicológicos das lutas territoriais, dos históricos de repressão violenta e da persistente cultura preconceituosa por parte do não indígena. Além disso, são evidentes o empenho e a dedicação do médico bolsista do Projeto Mais Médicos, bem como seu interesse em gerar cuidados para as comunidades tradicionais indígenas de seu polo de atuação, no entanto, vale ressaltar que mesmo após tantos anos da implementação do Projeto Mais Médicos, existe uma grande dificuldade no preenchimento de vagas destinadas ao atendimento nas comunidades indígenas e os últimos editais não conseguiram um médico para preenchimento da vaga em aberto para o polo de Paulo Afonso.

Actions for building a health service delivery model geared towards the indigenous population became more prominent only in 2002, upon creation of the National Health Policy for Indigenous Peoples. As a result, professionals from the Mais Médicos Project were included in the Special Indigenous Health Districts. Hence, this study describes the experience of professionals from the More Doctor for Brazil project within indigenous communities in northern Bahia, at the Paulo Afonso center. Overall, these communities face low socioeconomic conditions and the indigenous peoples of the Sertão are largely affected by urbanization processes. During the program, the professionals noted that indigenous communities bear the psychological effects of land struggles, the history of violent repression and the persistent prejudiced culture espoused by non-indigenous. Moreover, the commitment and dedication of Mais Médicos physicians, as well as their interest in providing care for the traditional indigenous communities in their area of activity, is evident. Importantly, however, even many years after the implementation of the Mais Médicos Project, vacancies geared towards indigenous health are difficult to fill out and the last public notices were unable to find a doctor to fill the open vacancy for the Paulo Afonso center.

Las acciones para construir un modelo de prestación de servicios de salud a la población indígena recién se intensificaron en el año 2002 cuando se creó la Política Nacional de Salud para los Pueblos Indígenas. De esta forma, se incluyó a profesionales en el Proyecto Más Médicos en los Distritos Sanitarios Especiales de Salud Indígena. Así, este trabajo describe la experiencia de profesionales del Proyecto Más Médicos para Brasil en comunidades indígenas del Norte de Bahía, en el polo Paulo Afonso. Estas comunidades se caracterizan por tener condiciones socioeconómicas bajas en general, y los pueblos indígenas del sertão del Nordeste Brasileño son en gran medida afectados por el proceso de urbanización. Durante el programa se pudo percibir que las comunidades indígenas traen consigo los efectos psicológicos de las luchas territoriales, la historia de represión violenta y la cultura prejuiciosa persistente por parte de los no indígenas. Además, es notorio el compromiso y dedicación del médico becario del Proyecto Más Médicos, así como su interés por brindar atención a las comunidades indígenas tradicionales de su zona de actuación; sin embargo, vale mencionar que aún después de tantos años de implementación del Proyecto Más Médicos, existe una gran dificultad para cubrir las vacantes destinadas a la atención de las comunidades indígenas y los últimos avisos públicos no encontraron a médicos para llenar la vacante abierta para el polo Paulo Afonso.

Modeling of covariates predicting renal allograft failure within six months after transplantation / Modelagem das covariáveis preditivas para falência do enxerto renal até seis meses do transplante

INTRODUCTION: Kidney transplantation (KT) is the renal replacement therapy (RRT) of choice for patients with chronic kidney disease (CKD). However, not every KT is successful and some patients persist on RRT. OBJECTIVE: To model a logistic regression with pre- and post-KT risk covariates capable of predicting secondary allograft dysfunction in need of RRT or reaching stage V of CKD until the first six months post-KT. METHODS: Cohort with KT recipients from Northeastern Brazil. Medical records of KT performed between 2011-2018 were analyzed. KT-recipients with insufficient data or who abandoned follow-up were excluded. The covariables analyzed were: demographic; infectious; pre- and post-KT comorbidities; panel reactive-antibodies; number of HLA mismatches; acute rejection episodes mediated by T-cell (ACR) or antibodies (AAR) six months after KT; and laboratory tests six months after KT. RESULTS: Covariates with higher risk for the analyzed outcomes six months after KT were: elderly KT recipients (OR:1.41; CI95%:1.01-1.99), time between onset of RRT and KT (ΔT-RRT&KT)>10years (OR:3.54; CI95%:1.27-9.87), diabetes mellitus (DM) pre-KT (OR:3.35; CI95%:1.51-7.46), pyelonephritis (OR:2.45; CI95%:1.24-4.84), polyomavirus nephropathy (OR:4.99; CI95%:1.87-13.3), AAS (OR:4.82; CI95%:1.35-17.2), 24h-proteinuria ≥300mg/24h (OR:5.05; CI95%:2.00-12.7) and serum calcium (Ca) <8.5mg/dL (OR:4.72; CI95%:2.00-11.1). The multivariate model presented an accuracy of 88.1% and the mean variance inflation factor is 1.81. CONCLUSION: Elderly-recipients, ΔT-RRT&KT>10 years, pre-KT DM, and post-KT aggressions until six months (pyelonephritis, polyomavirus nephropathy, ABMR, 24h-proteinuria≥300mg/24h, and Ca<8.5mg/dL) are associated with high predictive power for secondary allograft dysfunction in need of RRT or reaching CKD stage V until the first six months post-KT.

INTRODUÇÃO: Transplante renal (TR) é a terapia renal substitutiva (TRS) de escolha para pacientes com doença renal crônica (DRC). Entretanto, nem todo TR é bem-sucedido e alguns pacientes persistem em TRS. OBJETIVO: Modelar uma regressão logística com covariáveis de risco pré e pós-TR preditora da disfunção secundária do aloenxerto com necessidade de TRS ou alcance ao estágio V da DRC até os primeiros seis meses pós-TR. MÉTODOS: Coorte com receptores transplantados realizado em hospital no Nordeste brasileiro. Analisou-se registros médicos dos TR realizados entre 2011-2018. Receptores com dados insuficientes ou que abandonaram seguimento foram excluídos. Foram analisadas covariáveis: demográficas; infecciosas; comorbidades pré e pós-TR; painel de reatividade; incompatibilidades de HLA; episódios de rejeições agudas mediadas por células-T ou por anticorpos; exames laboratoriais seis meses pós-TR. RESULTADOS: Receptores idosos (OR:1,41; IC95%:1,01-1,99), tempo entre início da TRS e TR (∆T-TRS&TR)>10 anos (OR:3,54; IC95%:1,27-9,87), diabetes mellitus (DM) pré-TR (OR:3,35; IC95%:1,51-7,46), pielonefrite (OR:2,45; IC95%:1,24-4,84), nefropatia por poliomavírus (OR:4,99; IC95%:1,87-13,3), RAMA (OR:4,82; IC95%:1,35-17,2), proteinúria de 24h (Pt24h) ≥300mg/24h (OR:5,05; IC95%:2,00-12,7) e cálcio sérico (Ca)<8,5mg/dL (OR:4,72; IC95%:2,00-11,1) foram identificadas como covariáveis de maior risco para os desfechos analisados até seis meses pós-TR. O modelo multivariado apresentou acurácia de 88,1% e fator de inflação da variância médio de 1,81. CONCLUSÃO: Receptores idosos, ∆T-TRS&TR>10anos, DM pré-TR e agressões até seis meses pós-TR (pielonefrite, nefropatia por poliomavírus, RAMA, Pt24h≥300mg/24h e Ca<8,5mg/dL), apresentam alto poder preditivo para disfunção secundária do aloenxerto com necessidade de TRS ou alcance ao estágio V da DRC até os primeiros seis meses pós-TR.

Dados alarmantes sobre a notificação de sífilis congênita em uma capital do Norte brasileiro: um estudo transversal / Alarming data on the notification of congenital syphilis in a capital of the North of Brazil: a cross-sectional study

RESUMO: Modelo do estudo: Estudo de prevalência. Objetivo do estudo: Descrever o perfil clínico e epidemiológico dos portadores de Sífilis Congênita entre Janeiro de 2010 a Junho de 2016 em uma capital do Norte brasileiro. Metodologia: Foi realizado um levantamento das fichas de notificação para infecção por sífilis congênita da Vigilância Epidemiológica em Rio Branco-Acre no período de Janeiro 2010 a Junho de 2016. Os dados foram analisados por meio do Statistical Package for Social Sciences (SPSS). Resultados: Foram notificados 189 casos de sífilis congênita precoce. Apenas 36,51% (n=69) receberam diagnóstico de sífilis gestacional antes do parto. Os casos evoluíram com 74,6% de nascidos vivos, 15,3% de natimortos, 6,3% de abortos e 2,1% de óbitos por sífilis congênita. A relação entre o Venereal Disease Research Laboratory (VDRL) materno e o desfecho dos casos sugere que filhos provenientes de mães com títulos ≥1:16 representam 82,2% das evoluções deletérias associadas (p=0,045). Conclusão: A sífilis na gestação é uma patologia ainda subdiagnosticada durante a gravidez e, nesse estudo, foi mais frequente em filhos de mães no auge da menacme, de baixa escolaridade e moradoras da zona urbana. Apesar das medidas preventivas já implantadas, a sífilis congênita continua sendo um problema de saúde pública nesta capital do Norte brasileiro e deve continuar como alvo de estudos que gerem novas estratégias de prevenção.

ABSTRACT: Study model: A Prevalence study. Objective: Describing the clinical and epidemiological profile of patients with Congenital Syphilis between January 2010 and June 2016 in a capital city in the North of Brazil. Methodology: A survey was carried based on the reports of infection for congenital syphilis of the Epidemiological Surveillance in Rio Branco-Acre from January 2010 to June 2016. The data were analyzed through the SPSS Program. Results: 189 cases of early congenital syphilis were reported. Only 36.51% (n = 69) were diagnosed with gestational syphilis before delivery. The cases evolved with 74.6% of live births, 15.3% of stillborn infants, 6.3% of abortions, and 2.1% of congenital syphilis deaths. The relationship between the maternal VDRL and the outcome of the cases suggests that children from mothers with titles ≥1:16 represent 82.2% of the associated deleterious evolutions (p = 0.045). Conclusion: Congenital syphilis is a pathology still underdiagnosed during pregnancy and, in this study, was more frequent in children of mothers at the height of menacme, low schooling, and urban dwellers. Despite preventive measures already in place, congenital syphilis continues to be a public health problem in this capital of the Brazilian North and should continue to be the target of studies that generate new prevention strategies.

Pneumonia risk factors in stroke patients / Fatores de risco para pneumonia em pacientes com acidente vascular encefálico

ABSTRACT Purpose: to assess the demographic and clinical characteristics associated with the development of pneumonia in post-stroke patients hospitalized in a tertiary hospital, located in the Vale do São Francisco, that covers the states of Pernambuco and Bahia, Brazil. Methods: a unicentric, observational, analytical, cross-sectional study, based on the medical records of patients diagnosed with stroke and included in the Stroke Registry (RAVESS study). The statistical analysis was made with the chi-square test, Fisher's exact test, and the analysis of variance, with the Bonferroni's post-test, and P≤0.05. Results: data from 69 patients presented with acute stroke were collected, aged 63.2±16.8 years; 37 (53.6%) were females; the prevalence of pneumonia during hospital stay was estimated at 31.9% (95% confidence interval: 21.2-44.2%). In the univariate analysis of predictors for post-stroke pneumonia, the following were identified: older age (72.6±17.9 vs. 58.8±14.5; P = 0.001), lower response signal to the Glasgow Coma Scale at admission (11.3±1.8 vs. 13.3±2.1; P = 0.001), and higher frequency of dysarthria at admission (61.9% vs. 27.9%; P = 0.009). Conclusion: pneumonia was a prevalent complication in post-stroke patients at a Brazilian tertiary hospital. It was related to the patient's older age and the severity of the cerebral event.

RESUMO Objetivo: avaliar as características demográficas e clínicas associadas ao desenvolvimento de pneumonia em pacientes após acidente vascular encefálico internados em um hospital terciário do Vale do São Francisco que atende os estados de Pernambuco e Bahia, Brasil. Métodos: trata-se de estudo unicêntrico, observacional, analítico e transversal realizado a partir dos prontuários de pacientes com diagnóstico de acidente vascular encefálico incluídos no Registro de Acidente Vascular Encefálico (Estudo RAVESS). A análise estatística foi composta pelos testes qui-quadrado, exato de Fisher e a análise de variância com pós-teste de Bonferroni com nível de P≤0,05. Resultados: foram coletados dados de 69 pacientes com AVE agudo com média±desvio padrão de idade de 63,2±16,8 anos, sendo 37 (53,6%) do sexo feminino, com prevalência de pneumonia durante o internamento estimada em 31,9% (Intervalo de Confiança de 95%: 21,2-44,2%). Na análise univariada para preditores de pneumonia após acidente vascular encefálico foram identificados: idade mais avançada (72,6±17,9 vs. 58,8±14,5; P=0,001), menor sinal de resposta a escala de coma de Glasgow durante a admissão (11,3±1,8 vs. 13,3±2,1; P=0,001) e maior frequência de disartria na admissão (61,9% vs. 27,9%; P=0,009). Conclusão: a pneumonia foi uma complicação prevalente em pacientes após acidente vascular encefálico de um hospital terciário brasileiro, tendo sido relacionada com idade avançada do paciente e a severidade do evento encefálico.
