Tabanidae (Diptera) captured on horses in Amazon Forest fragments of the state of Rondônia, Brazil.

Tabanidae is one of the most diverse families of hematophagous dipterans. Tabanids, in general, are mechanical vectors of some pathogens. Given the vector importance and the lack of knowledge of the tabanid fauna in horses in Amazon Forest fragments of the state of Rondônia, this work aimed to determine the season that the different species of horse flies prefer to carryout hematophagy on horses and verify whether the horse fly community remains the same throughout the year. The sampling areas for tabanid captures were in the municipality of Monte Negro, Western Amazon, Brazil. Four new occurrences were recorded for the state of Rondônia: Stenotabanus albilinearis, Tabanus fuscofasciatus, T. macquarti and T. restrepoensis, which increases the number of species for the state to 109. The horse flies were most frequently collected on the hind leg (43.15%) and front leg (31.11%), followed by the belly (7.41%) and the ear (5.18%). In the other anatomical regions, the collection frequency was 13.15% of the remaining individuals.

Description of Tabanusrondoniensis (Diptera: Tabanidae), a new species of horsefly from the State of Rondônia, Brazil.

Background: The genus Tabanus Linnaeus has a worldwide distribution and is the richest in species; however, it is probably not monophyletic. In the Neotropical Region, its richness is certainly underestimated, mainly due to the large number of species and the absence of recent taxonomic revisions. New information: We describe Tabanusrondoniensis sp. n. from the State of Rondônia, Brazil, based on a conspicuous tabanid species possibly related to the T.nebulosus species group. Diagnosis, discussion and illustrations are also provided.

Prevalence of obesity, high blood pressure, dyslipidemia and their associated factors in children and adolescents in a municipality in the Brazilian Amazon region / Prevalência de obesidade, pressão arterial elevada e dislipidemia e seus fatores associados em crianças e adolescentes de um município amazônico, Brasil

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.

Survey of Trypanosoma (Kinetoplastida: Trypanosomatidae) Infection in Monte Negro Municipality, State of Rondônia, Western Amazon, with First Record of T. evansi in the state.

INTRODUCTION: Trypanosomes can infect humans and animals. This is the first record of the occurrence of Trypanosoma evansi in Rondônia. METHODS: Blood samples were collected from 7 dogs and 22 humans. Furthermore, triatomines and tabanids were collected. RESULTS: It was observed that 42.8% of the dogs tested positive for T. evansi and 14.3% presented mixed infection; 15% of the triatomines tested positive for flagellates identified as T. cruzi TCI (3 specimens), T. cruzi TCI, and T. rangeli (1 specimen), and one with T. cruzi TCV. Two tabanids were infected with T. theileri. CONCLUSIONS: These findings may benefit vector control strategies.
