RESUMEN
Importance: Bothrops venom acts almost immediately at the bite site and causes tissue damage. Objective: To investigate the feasibility and explore the safety and efficacy of low-level laser therapy (LLLT) in reducing the local manifestations of B atrox envenomations. Design, Setting, and Participants: This was a double-blind randomized clinical trial conducted at Fundação de Medicina Tropical Doutor Heitor Vieira Dourado, in Manaus, Brazil. A total of 60 adult participants were included from November 2020 to March 2022, with 30 in each group. Baseline characteristics on admission were similarly distributed between groups. Data analysis was performed from August to December 2022. Intervention: The intervention group received LLLT combined with regular antivenom treatment. The laser used was a gallium arsenide laser with 4 infrared laser emitters and 4 red laser emitters, 4 J/cm2 for 40 seconds at each application point. Main Outcomes and Measures: Feasibility was assessed by eligibility, recruitment, and retention rates; protocol fidelity; and patients' acceptability. The primary efficacy outcome of this study was myolysis estimated by the value of creatine kinase (U/L) on the third day of follow-up. Secondary efficacy outcomes were (1) pain intensity, (2) circumference measurement ratio, (3) extent of edema, (4) difference between the bite site temperature and that of the contralateral limb, (5) need for the use of analgesics, (6) frequency of secondary infections, and (7) necrosis. These outcomes were measured 48 hours after admission. Disability assessment was carried out from 4 to 6 months after patients' discharge. P values for outcomes were adjusted with Bonferroni correction. Results: A total of 60 patients (mean [SD] age, 43.2 [15.3] years; 8 female individuals [13%] and 52 male individuals [87%]) were included. The study was feasible, and patient retention and acceptability were high. Creatine kinase was significantly lower in the LLLT group (mean [SD], 163.7 [160.0] U/L) 48 hours after admission in relation to the comparator (412.4 [441.3] U/L) (P = .03). Mean (SD) pain intensity (2.9 [2.7] vs 5.0 [2.4]; P = .004), circumference measurement ratio (6.6% [6.6%] vs 17.1% [11.6%]; P < .001), and edema extent (25.8 [15.0] vs 40.1 [22.7] cm; P = .002) were significantly lower in the LLLT group in relation to the comparator. No difference was observed between the groups regarding the mean difference between the bite site temperature and the contralateral limb. Secondary infections, necrosis, disability outcomes, and the frequency of need for analgesics were similar in both groups. No adverse event was observed. Conclusions and Relevance: The data from this randomized clinical trial suggest that the use of LLLT was feasible and safe in a hospital setting and effective in reducing muscle damage and the local inflammatory process caused by B atrox envenomations. Trial Registration: Brazilian Registry of Clinical Trials Identifier: RBR-4qw4vf.

BACKGROUND: Pulmonary mycoses resemble clinically and radiologically chronic pulmonary tuberculosis. Studies describing the prevalence, etiology and clinical features of pulmonary mycosis are of crucial importance in the Brazilian Amazon. AIMS: To estimate the frequency of pulmonary mycoses in smear-negative tuberculosis patients; to describe their demographic, epidemiological, and clinical characteristics; and to evaluate diagnostic methods. METHODS: A cross-sectional study was conducted at two tuberculosis reference institutions in Amazonas, Brazil. We included 213 patients and collected clinical data, blood and induced sputum to perform serological, direct microscopy, microbiologic culture and PCR-based assays to identify infections caused by Aspergillus fumigatus, Paracoccidioides brasiliensis, Histoplasma capsulatum, Cryptococcus, and HIV. Chest computed tomography was also performed. RESULTS: Pulmonary mycoses were diagnosed in 7% (15/213) of the cases, comprising ten aspergillosis cases, three cases of paracoccidioidomycosis and one case each of histoplasmosis and cryptococcosis. Among the patients with pulmonary mycoses, 86.7% were former tuberculosis patients. The most significant clinical characteristics associated with pulmonary mycoses were cavity-shaped lung injuries, prolonged chronic cough and hemoptysis. CONCLUSIONS: Our study confirmed the high prevalence of pulmonary mycoses in smear-negative tuberculosis patients in the Brazilian Amazon.

OBJECTIVES: to compare the metabolic, anthropometric, tobacco and alcohol consumption indicators considered as risk factors for cardiovascular diseases, as well as the demographic and socioeconomic characteristics between indigenous from Rio Negro, Sateré-Mawé, mixed-race/black and white people living in the city of Manaus. METHODS: a cross-sectional observational study guided by the STROBE tool. There was a sample of 191 adults of both sexes. Anthropometric measurements, blood pressure and biochemical analyzes were performed. Statistical test was applied to cross color/race/ethnicity variable with the investigated variables. RESULTS: indigenous had better metabolic and anthropometric indicators related to cardiovascular diseases than mixed-race/black and white, as well as Sateré-Mawé in relation to Rionegrinos (from Rio Negro). CONCLUSIONS: the main differences were obesity, dyslipidemia, pre-systemic arterial hypertension/systemic arterial hypertension, and increased circumferences, with a worse situation for mixed-race/black people. The findings indicate differences in risk factors between race/color and ethnicity groups evaluated.

Visceral leishmaniasis (VL) may be influenced by climate and environmental factors. Tocantins is the state with the highest incidence in Brazil, contributing to the increase in the number of cases in the North macro-region. This study seeks to identify the correlation between VL incidence rates and climate and environmental factors in the municipalities of the State of Tocantins between 2007 and 2014. Correlations between crude VL incidence rates and the variables elevation, precipitation, Enhanced Vegetation Index (EVI) and temperature were tested using the Global and Local Moran Indexes, while also identifying clusters of VL incidence. We tested a variance analysis for linear trend between variable means in each rate category. Results show an increase in incidence rates with an increase in values of annual precipitation, humidity, EVI and nighttime temperature; and an inverse relationship with elevation and daytime temperature. The clusters we identified show that climate and environmental variables are related to VL incidence. Other studies are needed that adjust for individual-related factors in order to gauge how much the environment, or human influence over it, impact the disease.

INTRODUCTION: Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector's saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis. METHODS: We used ELISA to quantify the antibody levels in the sera and exposed chicken eggs. RESULTS: High IgY levels were observed following immunization; furthermore, higher reactivity was observed in the eggs and species-specific immune response was observed post final immunization. CONCLUSIONS: Chicken eggs can be used as sentinels to surveil vector saliva antibodies.

Abstract Objectives: to characterize the nutritional status of indigenous children underfive years of age living in rural communities in the Upper Solimões River region, inhabited by seven ethnic groups, based on data of december 2013. Methods: weight and height data extracted from SISVAN-I (Indigenous Food and Nutritional Surveillance System) forms filled in 2013 for 7,520 children (86.0% of the estimated children in this age group). The indices height-for-age (H/A), weight-for-age (W/A), weight-for-height(W/H), and body mass index-for-age (BMI/A) were calculated. Growth reference curves proposed by the World Health Organization were used to calculate z-scores. Results: the height-for-age (H/A) index presented the lowest mean z-score values, reaching -1.95 among children between 36 and 60 months. Mean z-score values for the weight-for-age (W/A) index also remained below zero. Mean z-score values for the indices weight-for-height (W/H) and body mass index-for-age (BMI/A) remained slightly above zero, reaching a maximum value of 0.5. Of all children, 45.7% presented low H/A, 9.6% presented low W/A, 4.5% presented low W/H, and 10.7% presented overweight based on BMI/A. Conclusion: our analysis show that in 2013 poor nutritional status persisted as an important health issue among these rural indigenous children.
Resumo Objetivos: caracterizar o estado nutricional de crianças indígenas menores de cinco anos, de comunidades rurais na região do Alto Solimões, habitada por sete etnias, com base em dados de dezembro de 2013. Métodos: foram extraídos dos formulários do SISVAN Indígena dados de peso e estatura, coletados em 2013, de 7.520 crianças (86,0% das crianças estimadas nesta faixa etária). Foram calculados os índices estatura-para-idade (E/I), peso-para-idade (P/I), peso-para-estatura (P/E) e índice de massa corporal para idade (IMC/I). Curvas de referência para crescimento propostas pela Organização Mundial da Saúde foram utilizadas para calcular escores z. Resultados: o índice estatura-para-idade (E/I) apresentou os menores valores médios de escore z, chegando a -1,95 nas crianças entre 36 e 60 meses. Os valores médios do escore z do índice peso-para-idade (P/I) também permaneceram abaixo de zero. Os valores médios do escore z para os índices P/E e índice de massa corporal para idade (IMC/I) mantiveram-se ligeiramente acima de zero, atingindo valor máximo de 0,5. Do total de crianças, 45,7% apresentaram baixa E/I, 9,6%, baixo P/I, 4,5% baixo P/E e 10,7% de excesso de peso de acordo com o IMC/I. Conclusão: em 2013 a desnutrição persistia como um importante agravo à saúde nessas crianças.

INTRODUCTION: Visceral leishmaniasis (VL) is a neglected disease, with territorial expansion and regional differences in Brazil that require explanation. This study aimed to describe changes in the epidemiology of VL in Brazil from 2001 to 2014. METHODS: The incidence rates, sociodemographic and clinical data, and case evolution were subgrouped from 2001 to 2006 and from 2007 to 2014 and presented descriptively. Spatial distribution of disease incidence rates and changes in the spatial and temporal pattern were examined. RESULTS: In total, 47,859 VL cases were reported in Brazil between 2001 and 2014, with predominance in the Northeast macroregion (55%), though the incidence rate in this region declined between the two study periods. The State of Tocantins had the highest crude rate (26.2/100,000 inhabitants), which was responsible for VL increasing in the North macroregion. VL predominated in the urban zone (70%), in children under 4 years (34%); however, an increase in the incidence of VL in adults older than 40 years was identified, with 12.3% and 31% in the first and second period, respectively. The mapping of crude rates and autochthonous canine cases showed territorial expansion. The temporal distribution of VL was consistent in Brazil in general, with no pattern observed, but regional differences were found. CONCLUSIONS: The incidence of VL is increasing in Brazil. In addition to the State of Tocantins, which had the highest rate, new outbreaks of VL have occurred in the South macroregion of Brazil with small decreases identified in the incidence rate in the Northeast.

INTRODUCTION: The incidence of chronic noncommunicable disease (CND) are rocketting over the world, including in young adults. The WHO estimates that more than half of the deaths in the world, even in underdeveloped countries, are caused by CND. OBJECTIVES: The study aimed to estimate the prevalence of obesity, high blood pressure (HBP) and dyslipidemia and its associated factors. METHODS: The authors carried out a cross-sectional study of 1,431 schools in the public-school system of Monte, Brazilian Western Amazon, with children and adolescents aged 6 to 15 years. A random sampling of 496 individuals was carried out. The OpenEpi platform was used to calculate the sample size, considering p<0.05 and a presumed prevalence of CND of 50%. The authors applied a clinical-epidemiological questionnaire, made anthropometric measurements and laboratory tests. Diagnostic parameters recommended by the recent guidelines of the Ministry of Health in Brazil were used. RESULTS: Prevalence of CND was: Obesity 11.8%, HBP of 6.7% and dyslipidemia of 25.4%. After multivariate log-binomial analysis of the dependent variables, the statistically significant risk factors were overweight 18.4%, sedentary lifestyle 32.2%, family history of cardiovascular disease 23.4%, family history of HBP 84.2%, family dyslipidemia 55.8%, family obesity 38.7% and family chronic renal disease 40.6%. CONCLUSION: The findings pointed out to a context with a relatively high prevalence of CND, as well as their associated factors. Intervention measures such as health education, food education, stimulation of physical exercise, better school feeding and an improvement of the public health system are needed to mitigate the occurrence of CND.
INTRODUÇÃO: A incidência de Doenças Crônicas Não Transmissíveis (DCNT) está aumentando em todo o mundo, inclusive em adultos jovens. A OMS estima que mais da metade das mortes no mundo, mesmo em países subdesenvolvidos, são causadas por DCNT. OBJETIVO: O estudo teve como objetivo estimar a prevalência de obesidade, pressão arterial elevada (PAE) e dislipidemia e seus fatores associados. MÉTODO: Os autores realizaram um estudo transversal com uma amostra randomizada de 496 de 1.431 alunos das escolas da rede pública de ensino de Monte Negro, Amazônia Ocidental, com crianças e adolescentes de 6 a 15 anos. Foi realizada uma amostragem aleatória de 496 indivíduos. Para o cálculo do tamanho da amostra foi utilizada a plataforma OpenEpi, considerando p <0,05 e prevalência presumida de DCNT de 50%. Os autores aplicaram um questionário clínico-epidemiológico, realizaram medidas antropométricas e exames laboratoriais. Foram utilizados parâmetros diagnósticos recomendados pelas diretrizes recentes do Ministério da Saúde do Brasil. Os dados foram analisados por por tetes estatísticos univariados e depois, multivariados, para se detectar associação entre causas e desfechos. RESULTADOS: A prevalência de DCNT foi: Obesidade 11,8%, Pressão Arterial Elevada de 6,7% e dislipidemia de 25,4%. Após análise log-binomial multivariada das variáveis dependentes, os fatores associados estatisticamente significativos foram sobrepeso 18,4%, sedentarismo 32,2%, história familiar de doença cardiovascular 23,4%, história familiar de hipertensão arterial sistêmica 84,2%, dislipidemia familiar 55,8%, obesidade familiar 38,7% e doença renal crônica familiar 40,6%. CONCLUSÃO: Os achados apontam para um contexto com prevalência relativamente elevada de DCNT, bem como seus fatores associados em crianças/adolescentes. Medidas de intervenção como educação em saúde, educação alimentar, estímulo à prática de exercícios físicos, melhor alimentação escolar e melhoria do sistema público de saúde são necessárias para mitigar a ocorrência de DCNT.

This study analyzes the number of medical appointments and referrals performed in primary health care in Brazil focusing on the Mais Médicos Program (More Doctors Program). It is a cross-sectional study on the work of physicians included, or not, to the Mais Médicos Program in 2014. Based on validation protocols, a unified database was created from two health information system databases - SIAB and ESUS. Absolute indicators were defined: the total of medical appointments per month; medical referrals and community health education activities. In addition, other indicators were considered, such as weekly rates and productivity of appointments, in line with the profile of Brazilian municipalities. The mean of all appointments was 285 per month corresponding to an average of 14.4 appointments/day. In the poorest municipalities, the figures for the Mais Médicos Program physicians were higher than national rates. The educational activities provided by primary care teams that included a Mais Médicos Program professional were higher in Brazilian capital cities. The Mais Médicos Program achieved one of its main goals, which was to increase health access for vulnerable populations and to contribute towards the consolidation of primary health care in Brazil.

Resumo: A leishmaniose visceral (LV) pode ser influenciada por fatores climáticos e ambientais. Tocantins é o estado com mais incidência no Brasil, contribuindo para o aumento dos casos na macrorregião Norte. Este estudo tem objetivo de identificar a correlação entre a taxa de incidência de LV e fatores climáticos e ambientais, nos municípios do Estado do Tocantins de 2007 a 2014. As correlações entre a taxa de incidência bruta de LV e as variáveis elevação, precipitação, Índice de Vegetação Melhorado (EVI - Enhanced Vegetation Index) e temperatura foram testadas por meio dos índices de Moran Global e Local, identificando também clusters de incidência de LV. A análise de variância para tendência linear foi testada entre as médias das variáveis em cada categoria da taxa. Os resultados apontam aumento nas taxas de incidência, na medida em que aumentam os valores de precipitação anual, umidade, EVI e temperatura noturna; e uma relação inversa para a elevação e temperatura diurna. Os clusters identificados evidenciam que variáveis climáticas e ambientais se relacionam à incidência de LV, devendo haver outros estudos que ajustem os fatores associados aos sujeitos, a fim de dimensionar o quanto o ambiente ou a influência do homem nele impacta na doença.

Resumen: La leishmaniasis visceral (LV) puede estar influenciada por factores climáticos y ambientales. Tocantins es el estado con más incidencia en Brasil, contribuyendo al aumento de casos en la macrorregión Norte. Este estudio tiene como objetivo identificar la correlación entre la tasa de incidencia de LV y los factores climáticos y ambientales, en municipios del Estado de Tocantins de 2007 a 2014. Las correlaciones entre la tasa de incidencia bruta de LV y las variables elevación, precipitación, Índice Mejorado de Vegetación (EVI - Enhanced Vegetation Index) y temperatura se comprobaron mediante los Índices de Moran Global y Local, identificando también clústeres de incidencia de LV. El análisis de varianza para la tendencia lineal se probó entre las medias de las variables en cada categoría de la tasa. Los resultados apuntan un aumento en las tasas de incidencia, a medida que aumentan los valores de precipitación anual, humedad, EVI y temperatura nocturna; y una relación inversa respecto a la elevación y temperatura diurna. Los clústeres identificados evidencian qué variables climáticas y ambientales se relacionan con la incidencia de LV, para lo que deben existir otros estudios que ajusten los factores asociados a los sujetos, con el fin de dimensionar lo mucho que el ambiente o la influencia del hombre impacta en la enfermedad.

Resumo O presente estudo analisa a produção de consultas e encaminhamentos médicos e das equipes da estratégia saúde da família realizados na atenção básica no Brasil, com o enfoque no Programa Mais Médicos (PMM). Estudo seccional sobre a produção de trabalho do médico e das equipes que pertencem ou não ao PMM em 2014 a partir de dados secundários do SIAB e ESUS. Foram construídos indicadores absolutos, como total de consultas médicas mensais, encaminhamentos médicos e atendimentos a grupos de educação em saúde, e indicadores relativos, como taxas e produtividade semanal de consultas médicas, segundo o perfil de municípios brasileiros. A mediana do total de consultas médicas no Brasil produzidas no Brasil foi de 285 por mês, o que corresponde a uma média de 14,4 consultas/dia. Nos municípios mais pobres, a produção e a produtividade de consultas pelos médicos do PMM foi mais elevada. O volume de atividades educativas e procedimentos da equipe com Mais Médicos foi maior nas capitais brasileiras. O PMM expandiu o acesso aos serviços de saúde nas regiões com maior vulnerabilidade social, contribuindo para a consolidação da atenção básica em todo o território brasileiro.
