ABSTRACT
Introduction: the prison system in the Brazilian state of Acre, located in the Western region of the Amazon, is a branch of the criminal justice system that has been suffering from issues such as overcrowding and growth in internal organized crime. The prevalence of these matters directly affects the resocialization of prisoners and inhibits the successful re-engineering of their social values and beliefs.Objective: to analyze the epidemiological profile of jailed women in the State of Acre, Brazil.Methods: in a cross-sectional descriptive study, 129 participants were recruited from female penitentiaries in the state of Acre. Conducted between August and December of 2017, data was collected through a validated questionnaire, divided into modules, using both open and closed-ended items.Results: we found that most women who participated in the study were single (n = 86, 66.7%), had brown skin (n = 93, 72.1%), had children (n=102, 79.1%), resided in the state of Acre (n=117, 90.5%). The mean age of the sample was 27.69 years. Among those participants who reported having partners (n = 40, 31%), we found that half had partners who were also incarcerated (n = 20, 50%). The study results also indicate that drug trafficking (n = 86, 66.7%) was the major cause for female incarceration, followed by homicide crime (n = 16, 12.4%). Over half of the participants were in prison for the first time (n = 75, 58.1%), with a high recidivism rate observed in the total sample (n = 54, 41.9%). A majority of the participants (n = 97, 75.2%) kept in touch with members of their families and a smaller portion (n = 15, 11.6%) received conjugal visits. With regard to social activities, slightly more than half (n = 75, 58.1%) worked and the majority (n = 114, 88.4%) did not study while jailed.Conclusion: the difficulties associated with accessing inmate data and the lack of peer-reviewed studies on inmate health in Brazil suggests that the public policies recommended by the PNSSP and the National Policy for Comprehensive Health Care for Women should be reevaluated.
Introdução: o sistema prisional no estado brasileiro do Acre, localizado na região ocidental da Amazônia, eÌ um ramo do sistema de justiça criminal que tem sofrido por situações como a superlotaçaÌo e o crescimento do crime organizado interno. A prevalência destas questões afeta diretamente a ressocializaçaÌo dos prisioneiros e inibe a preservaçaÌo bem sucedida dos seus valores e crenças sociais.Objetivo: analisar o perfil epidemioloÌgico das mulheres encarceradas no Estado do Acre, Brasil.Método: Estudo descritivo transversal, sendo que 129 participantes foram recrutadas em penitenciárias femininas no Estado do Acre. Conduzidos entre agosto e dezembro de 2017, os dados foram recolhidos através de um questionário validado, dividido em módulos, utilizando tanto artigos abertos como fechados.Resultados: verificamos que a maioria das mulheres que participaram no estudo eram solteiras (n = 86, 66,7%), tinham pele castanha (n = 93, 72,1%), tinham filhos (n = 102, 79,1%), residiam no estado do Acre (n = 117, 90,5%). A idade média da amostra foi de 27,69 anos. Entre os participantes que declararam ter parceiros (n = 40, 31%), descobrimos que metade tinha parceiros que também estavam encarcerados (n = 20, 50%). Os resultados do estudo indicam tambeÌm que o tráfico de drogas (n = 86, 66,7%) foi a principal causa de encarceramento feminino, seguido do crime de homicídio (n = 16, 12,4%). Mais de metade dos participantes estiveram na prisão pela primeira vez (n = 75, 58,1%), com uma elevada taxa de reincidência observada na amostra total (n = 54, 41,9%). A maioria dos participantes (n = 97, 75,2%) manteve-se em contato com membros das suas famílias e uma parte menor (n = 15, 11,6%) recebeu visitas conjugais. No que respeita aÌs atividades sociais, pouco mais de metade (n = 75, 58,1%) trabalhou e a maioria (n = 114, 88,4%) não estudou enquanto esteve presa.Conclusão: as dificuldades associadas ao acesso aos dados dos presos e a falta de estudos revistos por pares sobre a sauÌde dos presos no Brasil sugerem que as políticas puÌblicas recomendadas pelo Plano Nacional de SauÌde no Sistema Penitenciário - PNSSP e a Política Nacional de AtençaÌo Integral aÌ SauÌde da Mulher - PNAISM devem ser reavaliadas.
ABSTRACT
ABSTRACT Subsistence hunting is the main source of protein for forest reserve dwellers, contributing to the development of spurious infections by Calodium hepaticum, frequently associated with the consumption of the liver from wild mammals. The prevalence of infections by soil-transmitted helminths (STHs) and intestinal protozoa is considered an indicator of the social vulnerability of a country, besides providing information on habits, customs and quality of life of a given population. Intestinal parasites mostly affect poor rural communities with limited access to clean water and adequate sanitation. This study reports the results of a parasitological survey carried out in 2017 and 2019, in two municipalities (Xapuri and Sena Madureira) in Acre State. Stool samples were collected from 276 inhabitants. Upon receipt, each sample was divided into two aliquots. Fresh samples without preservative were processed and examined by the Kato-Katz technique. Samples fixed in 10% formalin were processed by the spontaneous sedimentation and the centrifugal sedimentation techniques. Calodium hepaticum eggs were found in three stool samples. The overall STH prevalence was 44.9%. The hookworm prevalence (19.2%) was higher than that of Ascaris lumbricoides (2.5%) and Trichuris trichiura (0.7%), an unexpected finding for municipalities belonging to the Western Brazilian Amazon. When considering parasites transmitted via the fecal-oral route, Endolimax nana and Entamoeba coli showed the highest positivity rates, of 13% and 10.9%, respectively. This study is the first report of spurious infection by C. hepaticum among forest reserve dwellers that consume undercooked liver of lowland pacas. Additionally, this is the first report of Blastocystis sp. in Acre State.
ABSTRACT
Resumo Introdução A Unidade de Assistência de Alta Complexidade em Oncologia (UNACON) permite o tratamento de leucemias agudas no Acre. Objetivo Determinar o perfil clínico-epidemiológico e a sobrevida hospitalar de leucemias agudas tratadas na UNACON/Acre entre 2007 e 2014. Método É um estudo longitudinal e retrospectivo de pacientes com leucemias agudas entre 15/06/2007 e 31/12/2014, cujos prontuários médicos forneceram dados para a análise descritiva das variáveis e posterior análise de sobrevida acumulada em 1 ano e 2 anos (método Kaplan-Meier) e comparação das curvas de sobrevida (teste de log-rank). Resultados A sobrevida para leucemias mieloides agudas (LMA) foi de 30% e 32% em 1 e 2 anos, respectivamente, com pior sobrevida para pacientes masculinos, brancos, ≥ 20 anos de idade, leucometria < 20.000 células/mm3, desidrogenase lática ≥ 600 U/dl e subtipo diferente do M3. Para leucemias linfoides agudas (LLA), a sobrevida foi de 59% e 45% em 1 e 2 anos, respectivamente, com pior sobrevida para sexo feminino, ≥ 20 anos de idade e leucometria elevada. Em pacientes abaixo de 20 anos de idade com LLA, a melhor sobrevida foi observada na faixa etária de 2 a 9 anos. Conclusão Trata-se do primeiro estudo epidemiológico de sobrevida realizado no Acre para leucemias agudas com resultados coerentes com a literatura. Contudo, novas pesquisas deverão ser realizadas.
Abstract Background The High Complexity Oncology Unit (Unidade de Assistência de Alta Complexidade em Oncologia - UNACON/Acre) allowed the treatment of acute leukemias in Acre. Objective To determine the clinical-epidemiological profile and hospital survival of acute leukemias treated at UNACON/Acre between 2007 and 2014. Method This is a longitudinal, retrospective study of patients with acute leukemias between 06/15/2007 and 12/31/2014 whose medical records provided data for descriptive analysis of the variables, and subsequent analysis of 1-year and 2-year cumulative survival (Kaplan Meier method) and comparison of survival curves (log-rank test). Results The survival for acute myeloid leukemia (AML) was 30 and 32% at 1 and 2 years, respectively, with a worse survival rate for males, white, age ≥20 years, leukometry <20,000 cells/mm3, lactic dehydrogenase ≥600 U/dl and subtype different from M3. For acute lymphoid leukemias (ALL), survival was 59 and 45% at 1 and 2 years, respectively. Female gender, age ≥20 years, and high leukometry had worse survival. For patients <20 years with ALL, better survival was observed in the age group of 2-9 years. Conclusion This is the first epidemiological study of survival in Acre for acute leukemias with results consistent with the literature. However, new studies should be performed.

ABSTRACT
Este estudo tem como objetivo trazer a perspectiva dos estudantes do Ensino Médio do Acre a respeito do Lazer. Foi desenvolvido estudo transversal com 674 estudantes do Ensino Médio de Instituições Federais das cinco regionais do Estado do Acre. Os dados foram coletados por meio de questionário composto por módulos temáticos com questões abertas e fechadas. Destaca-se como resultado: os estudantes consideram o lazer importante e o relacionam com a prática, como o lazer social e de atividades físicas; e destinam um tempo para sua vivência. As barreiras apontadas para a prática do lazer foram: cansaço, falta de tempo e de dinheiro. Os estudantes também indicam a insuficiência de espaços destinados ao lazer e atribuem este fato à falta de interesse do poder público. As atividades mais frequentes são as sociais, as físicas e intelectuais, sendo suas escolhas mais influenciadas pelo meio social.
This study aims to bring the perspective of high school students from the Acre, Brazil about Leisure. A cross-sectional study was developed with 674 students from Federal Institutions in five regions of the State of Acre. The data were collected through a questionnaire composed of thematic modules with open and closed questions. It stands out as a result: students consider leisure to be important and relate it to practice such as social and physical activity leisure; and they set time aside for their experience. The barriers pointed to the practice of leisure were: tiredness, lack of time and money. Students also indicate the insufficiency of leisure spaces and attribute this fact to the lack of interest from public authorities. The most frequent activities are social, physical and intellectual and their choices are more influenced by the social environment.

The reproductive efficiency of livestock is the basis for the success of livestock, dairy or beef, and having high reproductive performance depends on several factors within the production system and the presence of infectious diseases of the reproductive sphere in the herd is one of the factors that can compromise that efficiency. The aim of this study was to use molecular biology as a diagnostic tool for the detection of Leptospira spp. DNA in cows with reproductive disorders on a rural property in the municipality of Boca do Acre, Amazonas, Brazil. Vaginal mucus was collected from nine Nelore breeding cows with a history of abortion and birth of weak calves submitted to DNA extraction and nested-PCR technique for 16S gene amplification at the bacterial genus level. Of the nine samples analyzed, five (55.55%) amplified a product of 331bp. The municipality of Boca do Acre is bordered by Peru and Bolivia, and knowledge of the prevalence of the disease, serovars, and circulating Leptospira species is essential for the adoption of measures related to animal husbandry, as well as health education for ranchers and their workers to avoid a possible occupational infection since this disease is considered an important zoonosis. New molecular studies using primers that allow the identification of the Leptospira species and mainly pathogenic species should be conducted in this region in order to elucidate the possible species of this etiological agent and the possible reservoirs of the disease to begin the understanding of the epidemiology of this disease in cattle in this region of border.

This study addresses the clinical and epidemiological aspects of envenoming cases resulting from snakebites treated at a hospital in Cruzeiro do Sul, in the upper Juruá River region, western Brazilian Amazonia. The specific identity of snakes that caused the envenomings was inferred (a) from the diagnosis of patient symptoms and signs upon hospital admission, (b) by enzyme immunoassay for detection of Bothrops atrox and Lachesis muta venom from serum samples taken from patients before antivenom therapy, or (c) by direct identification of the snake, when it was brought along to the hospital or photographed. There were 133 snakebites (76.2 cases per 100,000 inhabitants) registered during one year (July 2017 to June 2018). Most snakebites (88.7%) were caused by Bothrops spp., and the rest by non-venomous snakes or dry bites. Snakebites tended to occur more often during the rainy season, coinciding with the period of greater reproductive activity of the snakes and greater availability of their prey. In addition, the increase in the water level of rivers and lakes during the rainy season tends to concentrate snakes in dry places and, thus, to increase encounters with humans. Information campaigns on prevention and first aid, specially among the most vulnerable groups (indigenous people, farmers, and children and teenagers in rural areas), and the importance of using protective equipment (boots, leggings, leather gloves) in certain high risk activities (e.g. agriculture and extractivism in forests) are fundamental for the reduction of snakebite morbidity.

Seed dispersal is one of the principal ecological processes that determine the richness and distribution of plants in tropical forests. Birds play an important role in the zoochoric dispersal of seeds in these forests.The present study investigated the bird-plant interactions involving the ingestion and dispersal of seeds by the birds found in the edge habitat of an isolated forest fragment on the Catuaba Experimental Farm in eastern Acre, in southwestern Brazilian Amazonia. The birds were captured using mist nets, and the seeds were collected from fecal samples obtained during the handling of the animals. These seeds were sorted and identified. The bird and the plant species identified during the study were used to calculate the connectivity and nestedness of the bird-plant interactions. We captured 82 species of birds, with a total sampling effort of 203,180 h.m². Fecal samples obtained from 19 of the bird species contained a total of 2,086 seeds, representing 23 plant species. The interaction network had an intermediate connectance, and significant nestedness. Ramphocelus carbohad the highest importance index and was the bird with the largest number of plant interactions, while Cecropia latilobawas the plant with the highest importance index, followed by Schefflera morototoni. Most of the seed-dispersing birds identified in the present study are generalists found in both the forest core and its edge. The results of the study indicated that the community of generalist-frugivore birds interacts extensively with the plant community of the fragment, providing seed dispersal services that include the deforested areas adjacent to the fragment.

Abstract INTRODUCTION: We examined the ethnobiological perception of the population of the Alto Juruá region about different snake species, in terms of their dangerousness and manifestations of envenomation. METHODS: We interviewed 100 villagers who were active in the forests. RESULTS: Lachesis muta was considered the most venomous snake, and Bothrops atrox appeared to be the most feared snake species. CONCLUSIONS: The high incidence, severity, and mortality of B. atrox bites and the severity and mortality of L. muta bites were the factors that contributed to these species being perceived as the most feared and venomous snakes.

Abstract In Brazil, species of the genus Ramphocelus with the presence of various endoparasites have already been reported. Coccidia have been the parasites most frequently found. All species of this genus have similar habitats and ecological niches, which makes parasite transmission easy. The aim of this study was to diagnose the presence of endoparasites in fecal samples from specimens of Ramphocelus carbo that were caught in the Cazumbá-Iracema Extractive Reserve (Cazumbá Resex), in the State of Acre. The specimens (n = 30) were caught in mist nets arranged in different ecosystems of the Reserve. After identification, the bird specimens were placed in cloth bags for a maximum of 30 minutes to collect feces. Among the 22 samples collected, 63.63% (n = 14) were positive for endoparasites. The coccidia were the parasites most frequently. Helminths belonging to Ascaridiidae (Nematoda), Strongylida (Nematoda) and Davaneidae (Cestoda) were recorded for the first time in R. carbo in the State of Acre. Parasites belonging to Strongylida and Davaneidae were recorded for the first time in a species of Ramphocelus. These findings add information on the parasitic fauna of wild birds, since in the Amazon region there are few studies on this subject.
Resumo No Brasil, espécies do gênero Ramphocelus ja foram relatadas com a presença de vários endoparasitos, sendo os coccídios os parasitos mais frequentes. Todas as espécies do gênero possuem habitats e nichos ecológicos semelhantes, facilitando a transmissão desses parasitos. O presente estudo teve como objetivo diagnosticar a presença de endoparasitos em amostras fecais de Ramphocelus carbo capturadas na Reserva Extrativista Cazumbá-Iracema (Resex do Cazumbá), localizada no estado do Acre. Os espécimes (n=30) foram capturados em redes de neblina dispostas em diferentes ecossistemas da Reserva. Após a identificação das aves, os espécimes foram colocadas em sacos de pano por no máximo 30 minutos para coleta das fezes. Das 22 amostras coletadas, 63,63% (n = 14) foram positivas para endoparasitas. Os coccídíos foram os parasitos mais frequentes. Os helmintos Ascaridiidae (Nematoda), Strongylida(Nematoda) e Davaneidae (Cestoda) foram registrados pela primeira vez em R. carbo, no estado do Acre. Strongylida e Davaneidae são registrados pela primeira vez em uma espécie pertencente a Ramphocelus. Esses achados acrescentam informações sobre a fauna parasitária de aves silvestres, pois na Amazônia existem poucos estudos nessa área.

Abstract INTRODUCTION: The popular names "surucucu" and "jararaca" have been used in literature for Lachesis muta and Bothrops atrox snakes, respectively. We present the popular names reported by patients who suffered snakebites in the Alto Juruá region. METHODS: Fifty-seven (76%) patients saw the snakes that caused the envenomations and were asked about their popular names and sizes. RESULTS: The snakes Bothrops atrox, referred to as "jararaca," were recognized as being mainly juveniles (80.7%) and "surucucu" as mainly adults (81.8%). CONCLUSIONS: The name "surucucu" is used in the Alto Juruá region for the snake B. atrox, mainly for adult specimens.

Abstract INTRODUCTION This study proposes to identify the Leishmania species found in the skin lesions of cutaneous leishmaniasis (CL) patients from Brasiléia municipality (Acre). METHODS Skin biopsy imprints or biopsy fragments were assayed via kDNA-PCR/RFLP and FRET-real-time PCR. RESULTS Of individuals with suspected CL, 18 were positive for Leishmania kDNA. Leishmania (Viannia) braziliensis (61.1%) and Leishmania (Viannia) guyanensis (5.5%) were identified in the positive samples. CONCLUSIONS These results are congruent with the previous reports in Acre and Bolivia, revealing L. braziliensis as the most prevalent species. L. guyanensis identification also corroborates with the epidemiology of the disease in the Amazon Basin.

Resumo O artigo analisa a construção do Relatório sobre as condições médico-sanitárias do vale do Amazonas, a partir das implicações macro e micropolíticas da passagem da expedição do Instituto Oswaldo Cruz pelos departamentos do território federal do Acre. Trata principalmente de seguir as relações de Carlos Chagas, Pacheco Leão e João Pedroso com juízes, médicos e seringalistas dos rios Iaco e Caeté na cidade de Sena Madureira, capital do Alto Purus, em janeiro de 1913. Aponta que esse relatório científico foi também produto do encontro dos cientistas-médicos com as elites seringalistas e da consequente imersão deles nos conflitos que animavam a política local e regional.
Abstract The writing of the Relatório sobre as condições médico-sanitárias do vale do Amazonas (Report on the medical and sanitary conditions in the Amazon Valley) is analyzed from the perspective of the macro- and micropolitical implications of the Instituto Oswaldo Cruz's expedition to the departments in the federal territory of Acre. The analysis focuses on the interactions between Carlos Chagas, Pacheco Leão, and João Pedroso and judges, doctors, and rubber barons from the Yaco and Caeté rivers at the town of Sena Madureira, capital of Alto Purus, in January 1913. The scientific report was also influenced by the contact the commission members had with the major players in the rubber industry and their resulting immersion in local and regional political conflicts.

This study reports a successful reproductive event in Megascops choliba in eastern Acre, northern Brazil. An active M. choliba nest was monitored from the hatching of the eggs to the departure of the nestlings. Once hatched, the nestlings were weighed every two days to verify their weight gain over time. The nestlings remained in the nest for 30 days. The pattern of weight gain was similar to that found in other birds, presenting a rapid increase over the first 15 days, followed by a drastic reduction in the mean growth rate during the second half of the development period. Our observations indicate that the breeding season of M. choliba in southwestern Amazonia is similar as that reported for the species in the northern hemisphere. These are the first data on this species from this region, and contribute to the understanding of its reproductive biology within its geographic range.
Este estudo refere-se a um caso bem sucedido de reprodução de Megascops choliba no leste do estado do Acre. Um ninho ativo de M. choliba foi acompanhado desde a eclosão até o abandono dos filhotes. A partir da eclosão, os filhotes foram pesados a cada dois dias. O tempo de permanência dos filhotes no ninho foi de 30 dias. O ganho de peso dos filhotes seguiu o padrão encontrado em outros estudos com aves, ou seja, um rápido aumento de peso nos primeiros 15 dias e uma redução drástica da taxa média de crescimento na segunda metade do período de desenvolvimento. Nossas observações indicam que o período reprodutivo de M. choliba no sudoeste amazônico deve ser o mesmo relatado para a espécie no hemisfério norte. Os dados apresentados aqui são inéditos para a região e contribuem para o entendimento da biologia reprodutiva desta espécie ao longo de sua distribuição geográfica.

The sandfly Trichophoromyia auraensis has recently evolved as a proven vector of Leishmania (Viannia) endemic to state of Acre in the north of Brazil. This note is intended to propose a correction in the report of the first occurrence of natural infection of Leishmania (Viannia) in this species. We and the other scientific groups reinforced that Tr. auraensis is a possible vector involved in the transmission of American cutaneous leishmaniasis in Acre, Brazil.

Este estudo avaliou as mudanças ambientais da paisagem urbana de um município com alta incidência de malária na Amazônia brasileira (Mâncio Lima, Acre) e sua relação com a doença, com o objetivo de prover evidências de que a transmissão do Plasmódio é causada pelo modo como os seres humanos interagem com o meio-ambiente. Foram efetuados três estudos populacionais consecutivos, entre 2012 e 2013, com 1260 indivíduos, com identificação do plasmódio por microscopia e técnicas moleculares. Casos de malária foram analisados mediante um questionário clinico. O estudo entomológico envolveu 8 inquéritos transversais com coleta de formas imaturas em 90 corpos dágua, bem como avaliação espacial desses dados. Os resultados mostraram que a transmissão de malária na área deveu-se em grande parte a criação de tanques de piscicultura, que elevaram em cerca de 10 vezes a produtividade de imaturos de Anopheles darlingi, e à grande mobilidade da população, que se desloca para áreas de maior transmissão (como área ribeirinha e rural) e retorna infectada para a área urbana. Foram identificados casos de portadores assintomáticos do Plasmódio, embora em pequena quantidade. Os fatores associados a ausência de sintomas (infecção assintomática) foram o sexo e o tempo da última malária. Em pacientes sintomáticos, a frequência dos sintomas se relacionou com idade, número de malárias previas e parasitemia. A concentração geográfica dos casos deveu-se em parte a características socioeconômicas agregadas no espaço, em conjunto com fatores ambientais como presença do vetor, visto que o uso infrequente de mosquiteiro associouse com a incidência maior de malária.
This study evaluated the environmental changes of the urban landscape of a municipality with a high incidence of malaria in the Brazilian Amazon (Mâncio Lima, Acre) and its relation with the disease, in order to provide evidence that the transmission of Plasmodium is caused by the way humans interact with the environment. Three consecutive population studies were carried out between 2012 and 2013, with 1260 individuals, with plasmodium identification by microscopy and molecular techniques. Malaria cases were analyzed using a clinical questionnaire. The entomological study involved 8 cross-sectional surveys with collection of immature forms in 90 bodies of water, as well as spatial evaluation of these data. The results showed that the transmission of malaria in the area was largely due to the creation of fish tanks, which increased the immature productivity of Anopheles darlingi by around 10 times, and the great mobility of the population, which moves to areas of greater transmission (as riverside and rural area) and returns infected to the urban area. Cases of asymptomatic Plasmodium carriers have been identified, albeit in small numbers. Factors associated with absence of symptoms (asymptomatic infection) were the sex and time of the last malaria. In symptomatic patients, the frequency of symptoms was related to age, number of previous malaria and parasitemia. The geographic concentration of the cases was due in part to aggregate socioeconomic characteristics in space, together with environmental factors such as vector presence, since the infrequent use of mosquito nets was associated with a higher incidence of malaria.

Studies on the sandfly fauna to evaluate natural infection indexes are still limited in the Brazilian Amazon, a region with an increasing incidence of cutaneous leishmaniasis. Here, by using a multiplex polymerase chain reaction directed to Leishmania kDNA and hybridisation, we were able to identify L. (Viannia) subgenus in 12 out of 173 sandflies captured in the municipality of Rio Branco, Acre state, revealing a positivity of 6.94%. By sequencing the Leishmania 234 bp-hsp70 amplified products from positive samples, infection by L. (V.) braziliensis was confirmed in five sandflies: one Evandromyia saulensis, three Trichophoromyia auraensis and one Pressatia sp. The finding of L. (Viannia) DNA in two Ev. saulensis corresponds to the first record of possible infection associated with this sandfly. Moreover, our study reveals for the first time in Brazil, Th. auraensis and Pressatia sp. infected by L. (Viannia) parasites.
