RESUMO

The coinfection between malaria (ML) and arboviral diseases represents a major global public health problem, particularly in tropical and subtropical countries. Despite its relevance, this topic is still insufficiently discussed in the current literature. Here, we aimed to investigate the worldwide distribution, symptoms, and diagnosis during coinfection between ML and arboviral diseases. We conducted a systematic review following the Preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement and assessed the selection and eligibility criteria, created and diagrammed maps, and analysed major symptoms with 95% confidence intervals (CI) using prevalence ratio and effect size, also performing latent class analysis. A total of 85,485 studies were retrieved, of which 56 were included: 57.14% in Asia, 25% in Africa, 14.30% in South America, and 3.56% in Europe. A total of 746 individuals were reported to be coinfected with Plasmodium and arbovirus. Concurrent ML, Dengue (DEN), Chikungunya (CHIK), and Zika (ZIK) patients are more likely to present headache and skin rash. Regarding diagnosis, 58,253 were made, of which 38,176 were positive (ML and at least one arboviral disease). The magnitude of these pathogens' coexistence points out the pressing need for improvements in public health policies towards diagnosis and prevention of both diseases, especially in endemic areas.

RESUMO

This study was carried out to identify the spatial distribution and characterize the clinical-epidemiological profile of Visceral Leishmaniasis (VL) in Maranhão state, Brazil, from 2009 to 2020. This descriptive ecological study collected sociodemographic and clinical data of VL cases from the Brazilian Notifiable Diseases Information System database. A spatial autocorrelation analysis (Moran statistics) was performed. From 2009 to 2020, 5699 cases of VL were reported, with incidence of 6.5 cases/100,000 and prevalence of 7.1 cases/100,000. The temporal analysis showed a significant growth in incidence from 2009 to 2018, followed by a significant decrease between 2019 and 2020. The Moran map shows hotspots of high values in the central-west and central-east regions, and hotspots of low values in the northern region of Maranhão. The profile of patients affected by VL comprises males (OR = 1.8; IC95% = 1.72-1.92), aged under 14 years, brown, and with incomplete elementary schooling. The main symptoms reported were fever, fatigue, and edema. The main diagnostic method was laboratory. The mortality rate was 6.8%, and co-infection with HIV was reported by 8.5% of patients. The results of this study indicated the increase in incidence and lethality, as well as the expansion, of leishmaniasis in the state of Maranhão.

RESUMO

Sporothrix brasiliensis is the most pathogenic species, responsible for the Brazilian cat-transmitted sporotrichosis hyperendemic. In this scenario, an investigation of the pathogen-host interaction can provide relevant information for future treatment strategies. To this end, the invertebrate Galleria mellonella has proven to be a suitable alternative for evaluating the virulence of pathogenic fungi, since the insect immune system is similar to the mammalian innate immune response. The aim of this work was to investigate phenotypic and molecular aspects of the immune response of G. mellonella throughout the S. brasiliensis infection. Hemocyte density and the evolution of the fungal load were evaluated. In parallel, RT-qPCR expression analysis of genes encoding antimicrobial peptides (Gallerimycin and Galiomycin) and stress management genes (C7 Contig 15362 and C8 Contig 19101) was conducted. The fungal load and hemocyte densities increased simultaneously and proportionally to the deleterious morphological events and larvae mortality. Gallerimycin, C7 Contig 15362 and C8 Contig 19101 genes were positively regulated (p < 0.05) at distinct moments of S. brasiliensis infection, characterizing a time-dependent and alternately modulated profile. Galiomycin gene expression remained unchanged. Our results contribute to the future proposal of potential alternative pathways for treating and consequently controlling S. brasiliensis zoonosis, a major public health issue in Latin America.

RESUMO

Potential variables for the reproductive success of beef cows were evaluated. Included in the model were the age of the cow at calving; the interval between the Julian calving date and the end of the breeding season; the body weight and conditions at calving, at 75 days post-partum and at the end of the breeding season; and the mean daily variation in weight between these dates. Logistic regression was used in the analysis, with the parameters evaluated using the odds ratio statistic, estimating the chance of pregnancy. The mean rate of pregnancy was 84% and 55% for early and late-weaned cows, respectively. For early weaned cows, the regression variables were the Julian calving date, age of the cow, weight gain from calving to 75 days post-partum, and from 75 days post-partum to the end of the reproductive period. For late-weaned cows, there were only two regression variables, weight at calving and weight gain from calving to the end of the reproductive period. For every year above the average age of the herd, early weaned cows have an 80.9% greater chance of pregnancy, while a reduction of one year reduces the chance of pregnancy by 44.7%. In early weaned cows, every seven days after the mean Julian calving date reduces the chances of pregnancy by 22.6%, whereas every seven days before the mean calving date increases pregnancy by 29.2%. Greater gains in cow body weight, from calving to the end of the reproductive period, determine a greater probability of pregnancy.

RESUMO

BACKGROUND: The innate immune response plays an important role during malaria. Toll-like receptors (TLR) are capable of recognizing pathogen molecules. We aimed to evaluate five polymorphisms in TLR-4, TLR-6, and TLR-9 genes and their association with cytokine levels and clinical parameters in malaria from the Brazil-French Guiana border. METHODS: A case-control study was conducted in Amapá, Brazil. P. vivax patients and individuals not infected were evaluated. Genotyping of five SNPs was carried out by qPCR. Circulating cytokines were measured by CBA. The MSP-119 IgG antibodies were performed by ELISA. RESULTS: An association between TLR4 A299G with parasitemia was observed. There was an increase for IFN-ɤ, TNF-ɑ, IL-6, and IL-10 in the TLR-4 A299G and T3911, TLR-6 S249P, and TLR-9 1486C/T, SNPs for the studied malarial groups. There were significant findings for the TLR-4 variants A299G and T3911, TLR-9 1237C/T, and 1486C/T. For the reactivity of MSP-119 antibodies levels, no significant results were found in malaria, and control groups. CONCLUSIONS: The profile of the immune response observed by polymorphisms in TLRs genes does not seem to be standard for all types of malaria infection around the world. This can depend on the human population and the species of Plasmodium.

RESUMO

Evidências científicas sugerem que o SARS-CoV-2 está nos tecidos orais na fase inicial da contaminação como principal reservatório viral. Além da cavidade oral ser o principal meio de propagação, também se torna uma localização comum das manifestações clínicas durante o início e a evolução da doença. O objetivo foi avaliar na literatura as manifestações clínicas orais e maxilofaciais decorrentes da contaminação pela Covid-19. Trata-se de uma revisão integrativa da literatura das bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), Scientific Electronic Library Online (Scielo) e BBO Odontologia, de artigos publicados entre os anos de 2019 e 2022 que retratassem a temática do estudo. Inicialmente, realizou-se a busca pelos descritores individualmente, em seguida, foram realizados os cruzamentos utilizando o operador booleano "AND" e, posteriormente, os três descritores foram cruzados em conjunto. Os critérios de inclusão foram: artigos publicados em português, inglês e espanhol, publicados e indexados nas referidas bases de dados, a partir de 2019 ­ ano do surgimento da Covid-19 e que retratassem a temática em estudo. Os critérios de exclusão foram: artigos publicados antes de 2019, artigos fora das bases de dados escolhidas e que fugissem da temática do estudo. Durante o estudo, 28 artigos foram selecionados a partir de todos os critérios citados. Conclui-se que pacientes contaminados com a Covid-19 tiveram manifestações clínicas orais e maxilofaciais que podem incluir ulcerações, inflamações na orofaringe, edemas retromandibulares, infecções fúngicas, xerostomia, anosmia e ageusia.


cientific evidence suggests that SARS-CoV-2 is present in the oral tissues in the initial phase of contamination as the main viral reservoir. Besides the oral cavity being the main means of spread, it also becomes a common location of clinical manifestations during the onset and evolution of the disease. The objective was to evaluate the literature about the oral and maxillofacial clinical manifestations arising from Covid-19 contamination. This is an integrative literature review of the databases Latin American and Caribbean Literature on Health Sciences (Lilacs), Scientific Electronic Library Online (Scielo) and BBO Dentistry, of articles published between 2019 and 2022 that portrayed the theme of the study. Initially, the search for the descriptors was conducted individually, then, the crossings were performed using the Boolean operator "AND" and, subsequently, the three descriptors were crossed together. The inclusion criteria were articles published in Portuguese, English and Spanish, published and indexed in the databases, starting in 2019 - year of the emergence of Covid-19 and that portrayed the theme of the study. The exclusion criteria were articles published before 2019, articles outside the chosen databases, and articles that ran away from the theme of the study. During the study, 28 articles were selected from all the cited criteria. It was concluded that patients contaminated with Covid-19 had oral and maxillofacial clinical manifestations that may include ulcerations, inflammation in the oropharynx, retromandibular edema, fungal infections, xerostomia, anosmia, and ageusia.

RESUMO

Trichophyton, Microsporum, Nannizzia and Epidermophyton genera cause dermatophytosis, the most common and highly contagious infectious skin disease. Rio de Janeiro is one of the most visited cities in the Southern Hemisphere, located in the most visited state of Brazil. This retrospective study investigated epidemiological and laboratorial aspects of dermatophytosis in Rio de Janeiro state, Brazil, by using spatiotemporal analysis. More than half of all individuals were infected by one or more dermatophytes. A variation between 18 and 106 years-old of the studied population was verified, and women more frequently affected. Patients were more frequently infected by Trichophyton spp., most of them T. rubrum, followed by T. mentagrophytes. M. canis and N. gypsea were more frequently isolated in the age group between 40 and 60 years old, while T. rubrum predominates among younger patients. All species presented homogeneous distribution while T. tonsurans appears to be restricted to the Rio de Janeiro capital and E. floccosum to the municipality of Macaé (190 Km apart from RJ). Rio de Janeiro state presented spatial clusters of dermatophytosis with high density in Guanabara Bay (E. floccosum, M. canis, N. gypsea, T. tonsurans) and Niterói (T. rubrum, T. mentagrophytes) but low density in Macaé (E. floccosum). Significant spatiotemporal clusters on dermatophytosis cases were detected in distinct municipalities (p-value ≤ 0.05). The Vulnerability Index (r = 0.293) and Demographic Density (r = 0.652) distributed according to neighborhoods in Niterói were direct related with dermatophytosis cases whereas Income (r = -0.306) was inversely correlated (p-value ≤ 0.05). The dermatophytosis spatiotemporal distinct distribution after two major international events in Rio de Janeiro, Brazil, highlight the pressing need for specific measures of its prevention and controlling. This is particularly relevant in touristic tropical localities which must consider both socio-economical and traveler's medicine variables.

RESUMO

Sporothrix brasiliensis with low susceptibility isolates were described from the Brazilian zoonotic sporotrichosis hyperendemics. The aim of this work was to evaluate distinct fractions of Ocotea pulchella, Ocotea notata, Myrciaria floribunda, and Hypericum brasiliense plant extracts against itraconazole-sensitive and low susceptibility S. brasiliensis isolates. Crude extracts were tested against clinical isolates and the ATCC MYA4823 to determine the minimum inhibitory concentrations (MICs) and fungicidal or fungistatic activities (MFC). A high MICs and MFCs amplitude (1 - > 128 µg/mL) were obtained for seven extracts. The highest antimicrobial activities against sensitive S. brasiliensis were displayed by the ethyl acetate extracts of O. notata (MIC = 2-128 µg/mL) and M. floribunda (MIC = 1-8 µg/mL). A fungicidal effect was observed for all fraction extracts. Ocotea spp. and M. floribunda ethyl acetate extracts provide promising profiles against itraconazole-sensitive or low susceptibility S. brasiliensis. Future studies will determine if these extracts can contribute as alternative therapies to this neglected zoonosis.

RESUMO

Determining what and how much each environmental factor affects pregnancy is crucial to the sustainability and management of beef cow herds. The study evaluated through logistic regression the effect of environmental variables on the increase or reduction in the pregnancy rate of beef cows. The average pregnancy rate in the cows was 73 %, with an average age for the herd of 3.7 years. An increase in age of one year represented a 30 % increase in pregnancy, while a reduction of one year reduced the odds of pregnancy in the cows by 23 %. During the lactation period, an extra seven days' lactation reduced the odds of pregnancy by 12 %. For every seven days that weaning was brought forward, the cows' pregnancy odds increased by 14 %. An increase of 0.1 kg in average daily gain represented an increase of 17 % and 15 % in the odds of pregnancy during the first 60 days post-partum and 60 days to the end of the reproductive period. On the other hand, the loss of 0.1 kg in average daily gain resulted in a 14 % and 13 % reduction in the cows' pregnancy odds, respectively. Factors such as age, the precocity of calving in the calving season, the time the calf remains with the cow and better performance in cows between calving and the end of the mating are strategies that increase the chances of pregnancy in beef cows.(AU)

RESUMO

Aspects related to good handling practices have significant impacts on animal behaviour with positive effects on the productivity and profitability of production systems. This study investigated the impact of good handling practices on the modification of stress indicators and the behaviour of beef cattle. Thirty-six male castrated bovines at the growth stage were evaluated for 490 days and submitted to two different production systems in Southern Brazil: good handling practices (GHP) and a traditional handling system of beef-cattle farming (THS). Body weight, reactivity indicators (flight distance and composite behaviour score), and blood indicators of stress (glucose and cortisol) were measured. An analysis of variance was carried out with measurements repeated over time, and Pearson's correlation applied between the variables mentioned above. No differences were found (P>0.05) for body weight in any of the evaluations, with initial weights of 196.2 and 196.3 kg and final weights of 431.0 and 413.8 kg for the GHP and THS steers, respectively. The GHP determined better values for the stress and behavioural indicators compared to THS (P<0.05). The flight distance of the GHP animals decreased from 11.33 to 5.22 metres from the first to the last evaluation, while in the THS animals the values were 10.17 and 11.89 metres, respectively. The behaviour composite score differed in the evaluations at 372 and 490 days, with values of 1.77 and 1.47 for GHP animals and values of 2.92 and 2.83 points for THS animals, respectively. Glucose and cortisol levels decreased with the advancing evaluations in GHP animals, with values from 94.80 to 74.22 mg/dL and from 6.08 to 3.68 µg/dL, respectively. In THS animals, glucose and cortisol levels were similar in the initial and final evaluations, with values of 89.30 and 91.28 mg/dL and 5.34 and 5.80 µg/dL, respectively. Regardless of the handling, the final body weight of the animals correlated negatively with the reactivity indicators and physiological stress indicators. The reactivity of the cattle is influenced by the quality of the human-animal interaction but has no effect on the performance of animals raised on pasture. Good handling practices reduce the reactivity and stress indicators of cattle.


Aspectos relacionados às boas práticas de manejo têm impactos significativos no comportamento animal com efeitos positivos na produtividade e lucratividade dos sistemas de produção. Este estudo investigou o impacto das boas práticas de manejo na modificação de indicadores de estresse e no comportamento de bovinos de corte. Trinta e seis bovinos, em fase de crescimento, foram avaliados por 490 dias e submetidos a dois diferentes sistemas de produção no sul do Brasil: boas práticas de manejo (BPM) e sistema de manejo tradicional da pecuária de corte (SMT). Foram avaliados o peso corporal, indicadores de reatividade (distância de fuga e escore composto de comportamento) e indicadores fisiológicos de estresse (glicose e cortisol no sangue). Foi realizada análise de variância com medidas repetidas ao longo do tempo e aplicada a correlação de Pearson entre as variáveis citadas anteriormente. Não foram encontradas diferenças para peso corporal em nenhuma das avaliações (P>0,05), com pesos iniciais de 196,2 e 196,3 kg e pesos finais de 431.0 e 413.8 kg para os novilhos BPM e SMT, respectivamente. O BPM determinou melhores valores para os indicadores fisiológicos de estresse e indicadores comportamentais em relação ao SMT (P<0,05). A distância de fuga dos animais BPM diminuiu de 11,33 para 5,22 metros da primeira avaliação para última avaliação, enquanto nos animais SMT os valores foram de 10,17 e 11,89 metros, respectivamente. O escore composto de comportamento diferiu nas avaliações aos 372 e 490 dias, com valores de 1,77 e 1,47 para animais BPM e valores de 2,92 e 2,83 pontos para animais SMT, respectivamente. Os níveis de glicose e cortisol diminuíram com o avanço das avaliações nos animais BPM com valores de 94,80 para 74,22 mg/dL e de 6,08 para 3,68 µg/dL, respectivamente. Nos animais SMT os níveis de glicose e cortisol foram semelhantes nas avaliações inicial e final com valores de 89,30 e 91,28 mg/dL e de 5,34 e 5,80 µg/dL, respectivamente. Independentemente do manejo ao qual os animais foram submetidos, o peso corporal final se correlacionou negativamente com os indicadores de reatividade e indicadores fisiológicos de estresse. A reatividade dos bovinos é influenciada pela qualidade da interação homem-animal, mas não tem efeito sobre o desempenho dos animais criados a pasto. Boas práticas de manejo reduzem a reatividade e os indicadores fisiológicos de estresse dos bovinos.

RESUMO

The aim was to identify the predominant variables in the differentiation of meat quality of cattle submitted to surgical castration, immunocastration, or non-castration and finished in a tropical pasture. Thirty-nine crossbred cattle were used and distributed in three treatments: i) surgical castration; ii) immunocastration; and iii) non-castration, with an initial mean age of 14.06±0.72 months and a mean weight of 284.10±31.40 kg. We used the principal component analysis to differentiate the qualitative meat characteristics between the treatments. Based on that analysis, we found that the first three principal components explained 71.44% of the total variation in the meat quality data, which ensures that the variation found is associated with the effect of the treatments. The characteristics correlated with the first three principal components and responsible for the discrimination between sexual conditions were subcutaneous fat thickness, instrumental meat color, cooking loss and shear force. These characteristics were similar among castrated animals, regardless of the methods. Therefore, immunological castration preserves the attributes of the meat and prevents possible damage to the physical and mental integrity of the animals. Finally, principal component analysis is an important methodology in the objective investigation of beef meat attributes.

RESUMO

Toll-like receptors (TLRs) play a key role in the induced immune response in malaria. Although the potential roles of TLRs have been described, it is necessary to elucidate which of these receptors may actually have an impact on the immunopathogenesis of the disease. This article performed a meta-analysis adhered to the PRISMA statement on TLRs studied in malaria by Plasmodium falciparum and Plasmodium vivax and its impact on susceptibility and pathogenesis during malaria. A search of the literature was undertaken in PubMed, LILACS and SciELO published until June 30th, 2020. The risk of bias was calculated using the Joanna Briggs Institute's Critical Review Checklist. Later, based on the inclusion and/or exclusion criteria, 17 out of 296 articles were harvested for this systematic review, the meta-analysis included studies incorporating 6,747 cases and 8,983 controls. The results showed that only TLR1, TLR9 and TLR4 receptors were associated with parasitemia, TLR2 and TLR6 were related with severity and none TLR was correlated with susceptibility. The data described here should be taken with caution, since the current evidence is limited and inconsistent. More studies are needed given that the results may change depending on the region and genetic background of the populations.

RESUMO

Recently, the well-known geographically wide distribution of sporotrichosis in Brazil, combined with the difficulties of effective domestic feline treatment, has emphasized the pressing need for new therapeutic alternatives. This work considers a range of synthetic derivatives as potential antifungals against Sporothrix brasiliensis isolated from cats from the hyperendemic Brazilian region. Six S. brasiliensis isolates from the sporotrichotic lesions of itraconazole responsive or non-responsive domestic cats were studied. The minimum inhibitory concentrations (MICs) of three novel hydrazone derivatives and eleven novel quinone derivatives were determined using the broth microdilution method (M38-A2). In silico tests were also used to predict the pharmacological profile and toxicity parameters of these synthetic derivatives. MICs and MFCs ranged from 1 to >128 µg/mL. The ADMET computational analysis failed to detect toxicity while a good pharmacological predictive profile, with parameters similar to itraconazole, was obtained. Three hydrazone derivatives were particularly promising candidates as antifungal agents against itraconazole-resistant S. brasiliensis from the Brazilian hyperendemic region. Since sporotrichosis is a neglected zoonosis currently spreading in Latin America, particularly in Brazil, the present data can contribute to its future control by alternative antifungal drug design against S. brasiliensis, the most virulent and prevalent species of the hyperendemic context.

RESUMO

Apesar de ser uma doença multifatorial, estudos indicam que a depressão pode estar associada a exposição a agrotóxicos. Objetivou-se descrever o perfil, aspectos de vida, trabalho e adoecimento de mulheres depressivas expostas a agrotóxicos em um município localizado no oeste do Paraná. Trata-se de pesquisa descritiva, qualitativa com 10 mulheres selecionadas a partir de inquérito populacional, por meio de entrevista com uma questão norteadora, no período de março a abril de 2017. As informações foram submetidas à análise temática. As mulheres tinham entre 18 e 65 anos de idade, baixa escolaridade e estavam inseridas no mercado de trabalho. A partir da análise das informações identificaram-se as seguintes temáticas: Início da vida laboral na infância, exposição a agrotóxicos durante longo período da vida sem proteção, aspectos da vida e do trabalho, história de exposição e intoxicação por agrotóxicos e; adoecimento por depressão. Sugerem-se estudos epidemiológicos e clínicos complementares sobre a relação desse fenômeno com o desenvolvimento de transtornos de humor. (AU)


Despite being a multifactorial disease, studies indicate that depression may be associated with exposure to pesticides. The objective was to describe the profile, aspects of life, work and illness of depressed women exposed to pesticides in a municipality located in the west of Paraná. This is a descriptive, qualitative research with 10 women selected from a population survey, through an interview with a guiding question, from March to April 2017. The information was submitted to thematic analysis. The women were between 18 and 65 years of age, with low education and were included in the labor market. From the information analysis, the following themes were identified: Beginning of working life in childhood, exposure to pesticides for a long life period without protection, life and work aspects, history of exposure and poisoning by pesticides and; illness due to depression. Complementary epidemiological and clinical studies are suggested on the relationship of this phenomenon with the development of mood disorders. (AU)

RESUMO

Sporotrichosis is a dermatozoonosis, caused by dimorphic pathogenic fungi of the genus Sporothrix. Although Sporothrix brasiliensis is the most frequent and pathogenic species identified from the Brazilian sporotrichosis hyperendemic, to the best of our knowledge this is the first report of its molecular diagnosis from a cat with ocular lesions. A 3-month-old female, domestic feline presented an ocular manifestation with granuloma in the lower-left palpebral conjunctiva, in addition to mucocutaneous lesions in varied locations throughout the body. Samples were collected for subsequent cytopathology, fungal culture, serology, and molecular genotyping. Itraconazole was prescribed for the treatment of sporotrichosis and the animal was considered clinically cured at the end of 5 months of treatment and discharged. S. brasiliensis-cat interactions can manifest with a multitude of clinical forms that resemble either infectious or noninfectious diseases. Both the need for meticulous cat physical evaluation by a veterinarian followed by accurate laboratory diagnosis are key Public Health measures in the Brazilian sporotrichosis hyperendemic area.(AU)


A esporotricose é uma dermatozoonose causada por fungos patogênicos dimórficos do gênero Sporothrix. Embora o Sporothrix brasiliensis seja a espécie mais patogênica e prevalente na hiperendemia brasileira de esporotricose, segundo nosso conhecimento este é o primeiro relato de um gato com lesões oculares causadas por esta espécie, via diagnóstico molecular. Um felino doméstico com três meses de idade apresentou manifestação ocular com granuloma em conjuntiva palpebral inferior esquerda, além de lesões mucocutâneas em diferentes áreas do corpo. Amostras foram coletadas para posterior citopatologia, cultura de fungos, sorologia e genotipagem molecular. O itraconazol foi prescrito para o tratamento da esporotricose e o animal foi considerado clinicamente curado ao final de cinco meses de tratamento, recebendo alta. As interações do S. brasiliensis com o gato podem se manifestar com uma infinidade de formas clínicas que se assemelham a doenças infecciosas ou não. A necessidade de avaliação física meticulosa desses animais por um médico veterinário, seguida do diagnóstico laboratorial preciso, são medidas essenciais em saúde pública na área hiperendêmica para a esporotricose no Brasil.(AU)

RESUMO

Background: Cervical cancer represents an important preventable cause of morbidity and mortality in developing countries such as Brazil. Investigating temporal evolution of a disease burden in the different realities of the country is essential for improving public policies. Objective: To describe the national and subnational burden of cervical cancer, based on the estimates of the 2017 Global Burden of Disease study. Methods: Descriptive study of premature mortality (years of life lost [YLL]) and burden of disease (disability-adjusted life years [DALYs]) associated with cervical cancer among Brazilian women aged 25-64 years, between 2000 and 2017. Findings: During the study period, age-standardized incidence decreased from 23.53 (22.79-24.26) to 18.39 (17.63-19.17) per 100,000 women, while mortality rates decreased from 11.3 (11.05-11.56) to 7.74 (7.49-8.02) per 100,000 women. These rates were about two to three times greater than equivalent rates in a developed country, such as England: 11.98 (11.45-12.55) to 10.37 (9.85-10.9), and 3.75 (3.68-3.84) to 2.82 (2.75-2.9) per 100,000 women, respectively. Poorer regions of Brazil had greater rates of the disease; for instance, Amapá State in the Northern Region had rates twice as high as the national rates during the same period. Cervical cancer was the leading cause of premature cancer-related mortality (YLL = 100.69, 91.48-110.61 per 100,000 women) among young women (25-29 years) in Brazil and eight federation units of all country regions except the Southeast in 2017. There was a decrease in the burden of cervical cancer in Brazil from 339.59 (330.82-348.83) DALYs per 100,000 women in 2000 to 238.99 (230.45-247.99) DALYs per 100,000 women in 2017. Conclusion: Although there has been a reduction in the burden of cervical cancer in Brazil, the rates remain high, mainly among young women. The persistence of inequalities between regions of Brazil suggests the importance of socioeconomic determinants in the burden for this cancer.
