Assessment of soil bacterial communities in integrated crop production systems within the Amazon Biome, Brazil: a comparative study.

Integrated production systems have been proposed as alternative to sustainable land use. However, information regarding bacterial community structure and diversity in soils of integrated Crop-Livestock-Forest systems remains unknown. We hypothesize that these integrated production systems, with their ecological intensification, can modulate the soil bacterial communities. However, Yet, it remains unclear whether the modulation of bacterial biodiversity is solely attributable to the complexity of root exudates or if seasonal climatic events also play a contributory role. The objective of this study is to evaluate the impact of monoculture and integrated production systems on bacterial soil communities in the Amazon Biome, Brazil. Three monoculture systems, each with a single crop over time and space (Eucalyptus (E), Crop Soybean (C), Pasture (P)), and three integrated systems with multiple crops over time and space (ECI, PI, ECPI) were evaluated, along with a Native forest serving as a reference area. Soil samples were collected at a depth of 0-10 cm during both the wet and dry seasons. Bacterial composition was determined using Illumina high-throughput sequencing of the 16 S rRNA gene. The sequencing results revealed the highest abundance classified under the phyla Firmicutes, Actinobacteria, and Proteobacteria. The Firmicutes correlated with the Crop in the rainy period and in the dry only ECPI and Forest. For five classes corresponding to the three phyla, the Crop stood out with the greatest fluctuations in their relative abundance compared to other production systems. In cluster analysis by genus during the rainy season, only Forest and ECPI showed no similarity with the other production systems. However, in the dry season, both were grouped with Forest and EPI. Therefore, the bacterial community in integrated systems proved to be sensitive to management practices, even with only two years of use. ECPI demonstrated the greatest similarity in bacterial structure to the Native forest, despite just two years of experimental deployment. Crop exhibited fluctuations in relative abundance in both seasons, indicating an unsustainable production system with changes in soil microbial composition. These findings support our hypothesis that integrated production systems and their ecological intensification, as exemplified by ECPI, can indeed modulate soil bacterial communities.

Changes in bacterial communities induced by integrated production systems and the phenological stages of soybean.

Plant development and productivity depend on interactions with soil microorganisms for nutrient availability, promotion of growth and protection against phytopathogens. Although the influence of the phenological stages of soybean crops and their environmental conditions on the soil bacterial communities have already been reported, no studies have focused on the influence of integrated agrosilvopastoral systems on bacterial consortia. In this study, we evaluated the influence of the phenological stages of soybean cultivated under conventional full sunlight (CFS) and integrated crop-livestock-forestry (ICLF) systems on bacterial communities in the rhizosphere and in bulk soil using high-throughput sequencing techniques. Proteobacteria, Actinobacteriota and Acidobacteriota were the most abundant phyla in both the rhizosphere and the bulk soil at all growth stages. The results support our hypotheses that the richness and diversity of soil bacterial communities are influenced by different cultivation systems, and that the structure of the bacterial communities in the rhizosphere and the bulk soil are modulated by the phenological stages of the soybean crop.

TRAIL-Sensitizing Effects of Flavonoids in Cancer.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) represents a promising anticancer agent, as it selectively induces apoptosis in transformed cells without altering the cellular machinery of healthy cells. Unfortunately, the presence of TRAIL resistance mechanisms in a variety of cancer types represents a major hurdle, thus limiting the use of TRAIL as a single agent. Accumulating studies have shown that TRAIL-mediated apoptosis can be facilitated in resistant tumors by combined treatment with antitumor agents, ranging from synthetic molecules to natural products. Among the latter, flavonoids, the most prevalent polyphenols in plants, have shown remarkable competence in improving TRAIL-driven apoptosis in resistant cell lines as well as tumor-bearing mice with minimal side effects. Here, we summarize the molecular mechanisms, such as the upregulation of death receptor (DR)4 and DR5 and downregulation of key anti-apoptotic proteins [e.g., cellular FLICE-inhibitory protein (c-FLIP), X-linked inhibitor of apoptosis protein (XIAP), survivin], underlying the TRAIL-sensitizing properties of different classes of flavonoids (e.g., flavones, flavonols, isoflavones, chalcones, prenylflavonoids). Finally, we discuss limitations, mainly related to bioavailability issues, and future perspectives regarding the clinical use of flavonoids as adjuvant agents in TRAIL-based therapies.

Critical exponents of master-node network model.

The dynamics of competing opinions in social network plays an important role in society, with many applications in diverse social contexts such as consensus, election, morality, and so on. Here, we study a model of interacting agents connected in networks in order to analyze their decision stochastic process. We consider a first-neighbor interaction between agents in a one-dimensional network with the shape of ring topology. Moreover, some agents are also connected to a hub, or master node, who has preferential choice or bias. Such connections are quenched. As the main results, we observed a continuous nonequilibrium phase transition to an absorbing state as a function of control parameters. By using the finite-size scaling method we analyzed the static and dynamic critical exponents to show that this model probably cannot match any universality class already known.

Compatibility Assessment of Novel Orodispersible Film Vehicle for Personalized Medicine with Selected Active Pharmaceutical Ingredients.

Orodispersible films (ODFs) are solid pharmaceutical forms for rapid local or systemic release of active ingredients. They are formed by a water-soluble polymer film that hydrates rapidly, adhering and dissolving immediately when placed on the tongue or in the oral cavity. In this paper, we describe the compatibility and disintegration times of compounded ODFs using OrPhylloTM, a new ready-to-use-vehicle, and APIs from different pharmacological classes, such as 5-hydroxytryptophan (5-HTP) 50 mg, bromopride 5 mg, coenzyme Q10 20 mg, melatonin 3 mg, resveratrol 5 mg, tadalafil 10 mg, vitamin B12 1 mg, or vitamin D3 2000 UI. ODFs were compounded and, subsequently, the samples were assayed using HPLC at initial (t = 0), 7 days (t = 7), 14 days (t = 14), 30 days (t = 30), 60 days (t = 60), 90 days (t = 90), 120 days (t = 120), 150 days (t = 150), and 180 days (t = 180) after compounding. Given the percentage of recovery of the APIs within the films, the beyond-use date of the final products (API + vehicle) was at least 90 days for vitamin D3, 150 days for bromopride and 5-HTP, and 180 days for coenzyme Q10, tadalafil, vitamin B12, resveratrol, and melatonin, when stored at room temperature. The average disintegration time was 46.22 s. This suggests that the OrPhylloTM vehicle is suitable for compounding ODFs with APIs from different pharmacological classes, with good compatibility and fast disintegration.

Prevalence of trachoma in the non-indigenous Baixo Jaguaribe micro-region, Ceará State, Northeast Brazil.

BACKGROUND: The aim of the current study was to estimate the population prevalence of trachoma in non-indigenous populations in the Baixo Jaguaribe micro-region, in the state of Ceará, northeast region of Brazil, 2021-2022. METHODS: A population-based prevalence survey focusing on detecting cases of trachomatous inflammation-follicular (TF) in children aged 1-9 y and trachomatous trichiasis (TT) 'unknown to the health system' in people aged ≥15 y, was conducted in rural areas of the Baixo Jaguaribe micro-region in the state of Ceará. Indigenous populations will be further researched. RESULTS: There was no detection of cases of TF and TT. In 900 households, 2234 people were examined. In the Baixo Jaguaribe micro-region, females (54.6%; 1219/2234) and the mixed/Pardo-Brazilian ethnicity (68.1%; 1521/2234) predominated. The most commonly reported educational level was elementary and middle school (41.8%; 702/1679). In 56.2% (506/900) of households, there was a source of water within the household. The monthly income range of 50%-100% of the minimum wage predominated in the families of the Baixo Jaguaribe micro-region (43.1%; 388/900). CONCLUSIONS: Although no cases of TF and TT were detected in the Baixo Jaguaribe micro-region in the state of Ceará during the study period, considering the historical endemicity, we emphasise the need for monitoring and sustainability of surveillance actions in areas at risk for trachoma, common contexts for neglected populations.

Diet of Moenkhausia bonita (Benine, Castro & Sabino 2004) (Characiformes: Characidae) in streams in the basin of rio Formoso, Brazilian Midwest

To characterize the diet composition of Moenkhausia bonita and its temporal and ontogenetic variations in streams in the Formoso River basin (MS). The collections were carried out in seven sampling points in two periods throughout the year (dry and rainy). The food items were analyzed according to the volumetric and occurrence frequency methods and the diet was characterized through the Food Index (IAi%). To determine ontogeny, the specimens were divided into five size classes in the dry (D1 to D5) and rainy (R1 to R5) periods. To verify the difference between the species' diet between the size classes and the periods of the year, the Permutational Multivariate Analysis of Variance ­ PERMANOVA analysis was performed. Moenkhausia bonita was classified as an invertivore when it consumed basically both aquatic and terrestrial invertebrates (99.5% of the diet), with higher consumption of aquatic invertebrates. There was a significant difference in the diet of between the dry and rainy periods, and although the species basically consumed the same items in the two studied periods, the proportions were different and there was no difference in the diet between size classes. M. bonita diet is based on autochthonous resources regardless of the size class, but that there were different consumption patterns when comparing the different periods of the year. The present study provided the first information on the feeding of M. bonita in a lotic environment and diet spectrum in the developmental phases, (ontogeny) and periods of the year, enabling a better understanding of the species, the importance of invertebrates in its diet, and the need for future studies on the biology, autoecology, and behavior of this species.

Cardiac disturbances and changes in tissue cytokine levels in mice fed with a high-refined carbohydrate diet.

AIMS: The consumption of highly refined carbohydrates increases systemic inflammatory markers, but its potential to exert direct myocardial inflammation is uncertain. Herein, we addressed the impact of a high-refined carbohydrate (HC) diet on mice heart and local inflammation over time. MAIN METHODS: BALB/c mice were fed with a standard chow (control) or an isocaloric HC diet for 2, 4, or 8 weeks (HC groups), in which the morphometry of heart sections and contractile analyses by invasive catheterization and Langendorff-perfused hearts were assessed. Cytokines levels by ELISA, matrix metalloproteinase (MMP) activity by zymography, in situ reactive oxygen species (ROS) staining and lipid peroxidation-induced TBARS levels, were also determined. KEY FINDINGS: HC diet fed mice displayed left ventricular hypertrophy and interstitial fibrosis in all times analyzed, which was confirmed by echocardiographic analyses of 8HC group. Impaired contractility indices of HC groups were observed by left ventricular catheterization, whereas ex vivo and in vitro indices of contraction under isoprenaline-stimulation were higher in HC-fed mice compared with controls. Peak levels of TNF-α, TGF-ß, ROS, TBARS, and MMP-2 occur independently of HC diet time. However, a long-lasting local reduction of the anti-inflammatory cytokine IL-10 was found, which was linearly correlated to the decline of systolic function in vivo. SIGNIFICANCE: Altogether, the results indicate that short-term consumption of HC diet negatively impacts the balance of anti-inflammatory defenses and proinflammatory/profibrotic mediators in the heart, which can contribute to HC diet-induced morphofunctional cardiac alterations.

Anthelmintic Drugs as Emerging Immune Modulators in Cancer.

Despite recent advances in treatment approaches, cancer is still one of the leading causes of death worldwide. Restoration of tumor immune surveillance represents a valid strategy to overcome the acquired resistance and cytotoxicity of conventional therapies in oncology and immunotherapeutic drugs, such as immune checkpoint inhibitors and immunogenic cell death inducers, and has substantially progressed the treatment of several malignancies and improved the clinical management of advanced disease. Unfortunately, because of tumor-intrinsic and/or -extrinsic mechanisms for escaping immune surveillance, only a fraction of patients clinically respond to and benefit from cancer immunotherapy. Accumulating evidence derived from studies of drug repositioning, that is, the strategy to identify new uses for approved or investigational drugs that are outside the scope of the original medical indication, has suggested that some anthelmintic drugs, in addition to their antineoplastic effects, exert important immunomodulatory actions on specific subsets of immune cell and related pathways. In this review, we report and discuss current knowledge on the impact of anthelmintic drugs on host immunity and their potential implication in cancer immunotherapy.

: Caracterizar a composição alimentar de Moenkhausia bonita e as variações temporais e ontogenéticas na dieta desta espécie em riachos da bacia do rio Formoso (MS). As coletas foram realizadas em sete pontos amostrais em dois períodos do ano (seco e chuvoso). Os itens alimentares foram analisados de acordo com os métodos volumétrico e de frequência de ocorrência e a dieta foi caracterizada através do Índice Alimentar (IAi%). Para determinar a ontogenia, os espécimes foram divididos em cinco classes de tamanho nos períodos seco (D1 a D5) e chuvoso (R1 a R5). Para verificar a diferença entre a dieta da espécie entre as classes de tamanho e os períodos do ano foi realizado a Análise de Variância Multivariada Permutacional ­ PERMANOVA. M. bonita foi classificada como invertívora ao consumir basicamente invertebrados tanto aquáticos quanto terrestres (99,5% da dieta), com consumo maior de invertebrados aquáticos. Houve diferença significativa na dieta entre os períodos seco e chuvoso, apesar da espécie consumir basicamente os mesmos itens nos dois períodos estudados, as proporções foram distintas e não houve diferença na dieta entre as classes de tamanho. A dieta de M. bonita é baseada em recursos autóctones independente da classe de tamanho, mas que houve consumo diferente entre os períodos do ano. O presente estudo forneceu as primeiras informações sobre a alimentação de M. bonita em ambiente lótico e seu espectro alimentar nas fases de desenvolvimento(ontogenia)e períodos do ano, possibilitando melhor conhecimento da espécie, a importância dos invertebrados em sua dieta e a necessidade de estudos futuros sobre a biologia, autoecologia e comportamento desta espécie.

Judicialization of the right to health with a focus on neglected tropical diseases: dimensions and challenges in Piauí State, Northeastern Brazil, 2000-2020. / Judicialização do direito à saúde com foco em doenças tropicais negligenciadas: dimensões e desafios no Estado do Piauí, Nordeste do Brasil, 2000-2020.

This article aims to analyse the magnitude and profile of legal demands for public health goods and services, also verifying the presence of legal demands for neglected tropical diseases (NTDs) in the State of Piauí between 2000-2020. Cross-sectional descriptive study based on the databases of the Court of Justice of Piauí on lawsuits demanding from the Direct Public Administration, goods and health services. A total of 6,658 lawsuits were initially identified. After eligibility analysis, 1,384 cases (20.8%) were analysed, with an increase in demand from 2017. We highlight the characteristics: origin in the capital Teresina (614; 44.4%), 40 to 59 years of age (372; 26.9%), female (761; 55.0%), farmers (123; 8.9%), public legal assistance (1,063; 76.8%), upheld (594; 42.9%). Five (5; 0.4%) lawsuits for NTDs, one visceral leishmaniasis requesting transportation, with granting, four for leprosy (two medicines, one granted, other extinguished without resolution of the merit, one consultation and one exam granted). The judicialization of the right to health is expressive and growing in the State of Piauí. The low demand related to NTDs may translate into limited access not only to health care, but also to the judiciary.

A judicialização do direito à saúde é expressiva e crescente no estado do Piauí. A baixa demanda relacionada a DTNs pode traduzir limitação de acesso não apenas à saúde, mas ao Poder Judiciário.

Epidemiology and control of trachoma in the state of Ceará, Northeast Brazil, 2007-2021.

BACKGROUND: To analyze the epidemiology, surveillance, and control strategies for trachoma in the state of Ceará, northeast Brazil, from 2007 to 2021. METHODS: This ecological study was based on secondary data from the Information System on Notifiable Diseases of the Secretary of Health of the state of Ceará. Data from school and home surveys for trachoma detection obtained during the study period were analyzed, the percentage of positivity was estimated, and sociodemographic and clinico-epidemiological factors were investigated. RESULTS: The coverage of trachoma surveillance and control actions in Ceará municipalities increased from 12.5% in 2007 to 55.9% in 2019, but with an average restriction of 8.0% during the COVID-19 pandemic. The estimated trachoma positivity (mean overall positivity) was less than 5.0% (2.76%, 95% CI 1.2-5.2), with a higher proportion of cases in the 5-9-year age group (45.0%, 95% CI 44.6-45.4), in females (53.2%, 95% CI 52.8-53.6), and rural areas (52.6%, 95% CI 52.2-53.0). Positivity above 10.0% was observed in the Litoral Leste/Jaguaribe and Sertão Central regions, with a higher occurrence of the follicular inflammatory clinical form (98.1%, 95% CI 98.0-98.2). CONCLUSIONS: Trachoma remains in the state of Ceará and is likely underreported. Despite recent advances, the fragility of health surveillance activities compromises the recognition of the actual magnitude and distribution of trachoma in the state. Accurate information is fundamental for planning, monitoring, and evaluating surveillance and disease control.

Scientometric review of research on Neglected Tropical Diseases: a 31-year perspective from the Journal of the Brazilian Society of Tropical Medicine.

BACKGROUND: To analyze the temporal evolution of research on Neglected Tropical Diseases (NTDs) published by the Journal of the Brazilian Society of Tropical Medicine (JBSTM). METHODS: We performed an analysis of the scientific production in JBSTM on NTDs using an advanced search, which included authors' descriptors, title, and abstract, and by combining specific terms for each NTDs from 1991 to 2021. Data related to authors, countries of origin, institutions, and descriptors, were evaluated and analyzed over time. Bibliographic networks were constructed using VOSviewer 1.6.16. RESULTS: The JBSTM published 4,268 scientific papers during this period. Of these 1,849 (43.3%) were related to NTDs. The number of publications on NTDs increased by approximately 2.4-fold, from 352 (total 724) during 1991-2000 to 841 (total 2,128) during 2011-2021, despite the proportional reduction (48.6% versus 39.5%). The most common singular NTDs subject of publications included Chagas disease (31.4%; 581/1,849), leishmaniasis (25.5%, 411/1,849), dengue (9.4%, 174/1,849), schistosomiasis (9.0%; 166/1,849), and leprosy (6.5%, 120/1,849), with authorship mostly from Brazil's South and Southeast regions. CONCLUSIONS: Despite the proportional reduction in publications, JBSTM remains an important vehicle for disseminating research on NTDs during this period. There is a need to strengthen the research and subsequent publications on specific NTDs. Institutions working and publishing on NTDs in the country were concentrated in the South and Southeast regions, requiring additional investments in institutions in other regions of the country.

Abstract This article aims to analyse the magnitude and profile of legal demands for public health goods and services, also verifying the presence of legal demands for neglected tropical diseases (NTDs) in the State of Piauí between 2000-2020. Cross-sectional descriptive study based on the databases of the Court of Justice of Piauí on lawsuits demanding from the Direct Public Administration, goods and health services. A total of 6,658 lawsuits were initially identified. After eligibility analysis, 1,384 cases (20.8%) were analysed, with an increase in demand from 2017. We highlight the characteristics: origin in the capital Teresina (614; 44.4%), 40 to 59 years of age (372; 26.9%), female (761; 55.0%), farmers (123; 8.9%), public legal assistance (1,063; 76.8%), upheld (594; 42.9%). Five (5; 0.4%) lawsuits for NTDs, one visceral leishmaniasis requesting transportation, with granting, four for leprosy (two medicines, one granted, other extinguished without resolution of the merit, one consultation and one exam granted). The judicialization of the right to health is expressive and growing in the State of Piauí. The low demand related to NTDs may translate into limited access not only to health care, but also to the judiciary.

NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics.

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

Epidemiology and control of trachoma in the state of Ceará, Northeast Brazil, 2007-2021

ABSTRACT Background: To analyze the epidemiology, surveillance, and control strategies for trachoma in the state of Ceará, northeast Brazil, from 2007 to 2021. Methods: This ecological study was based on secondary data from the Information System on Notifiable Diseases of the Secretary of Health of the state of Ceará. Data from school and home surveys for trachoma detection obtained during the study period were analyzed, the percentage of positivity was estimated, and sociodemographic and clinico-epidemiological factors were investigated. Results: The coverage of trachoma surveillance and control actions in Ceará municipalities increased from 12.5% in 2007 to 55.9% in 2019, but with an average restriction of 8.0% during the COVID-19 pandemic. The estimated trachoma positivity (mean overall positivity) was less than 5.0% (2.76%, 95% CI 1.2-5.2), with a higher proportion of cases in the 5-9-year age group (45.0%, 95% CI 44.6-45.4), in females (53.2%, 95% CI 52.8-53.6), and rural areas (52.6%, 95% CI 52.2-53.0). Positivity above 10.0% was observed in the Litoral Leste/Jaguaribe and Sertão Central regions, with a higher occurrence of the follicular inflammatory clinical form (98.1%, 95% CI 98.0-98.2). Conclusions: Trachoma remains in the state of Ceará and is likely underreported. Despite recent advances, the fragility of health surveillance activities compromises the recognition of the actual magnitude and distribution of trachoma in the state. Accurate information is fundamental for planning, monitoring, and evaluating surveillance and disease control.

Scientometric review of research on Neglected Tropical Diseases: a 31-year perspective from the Journal of the Brazilian Society of Tropical Medicine

ABSTRACT Background: To analyze the temporal evolution of research on Neglected Tropical Diseases (NTDs) published by the Journal of the Brazilian Society of Tropical Medicine (JBSTM). Methods: We performed an analysis of the scientific production in JBSTM on NTDs using an advanced search, which included authors' descriptors, title, and abstract, and by combining specific terms for each NTDs from 1991 to 2021. Data related to authors, countries of origin, institutions, and descriptors, were evaluated and analyzed over time. Bibliographic networks were constructed using VOSviewer 1.6.16. Results: The JBSTM published 4,268 scientific papers during this period. Of these 1,849 (43.3%) were related to NTDs. The number of publications on NTDs increased by approximately 2.4-fold, from 352 (total 724) during 1991-2000 to 841 (total 2,128) during 2011-2021, despite the proportional reduction (48.6% versus 39.5%). The most common singular NTDs subject of publications included Chagas disease (31.4%; 581/1,849), leishmaniasis (25.5%, 411/1,849), dengue (9.4%, 174/1,849), schistosomiasis (9.0%; 166/1,849), and leprosy (6.5%, 120/1,849), with authorship mostly from Brazil's South and Southeast regions. Conclusions: Despite the proportional reduction in publications, JBSTM remains an important vehicle for disseminating research on NTDs during this period. There is a need to strengthen the research and subsequent publications on specific NTDs. Institutions working and publishing on NTDs in the country were concentrated in the South and Southeast regions, requiring additional investments in institutions in other regions of the country.

Scientometric analysis of research on trachoma in Brazil, 2000-2020.

OBJECTIVE: To analyze the scientometric profile of research on trachoma in Brazil. METHODS: Bibliographic research of publications on trachoma in Brazil indexed by the Scopus database from 2000 to 2020, based on specific criteria. Data on authorship, country of origin, institutions, and keywords were collected and analyzed with analysis of time trends. Bibliographic networks were constructed via a scientometric visualization software-VOSviewer® 1.6.16. RESULTS: We analyzed 42 publications on trachoma in Brazil. The annual average was two articles, with an increase of about 50% during the period. The average number of authors was three per document and school surveys were the most common subject category. Most published articles came from Brazilian institutions (95.2%), mainly those based in Southeast and North Brazil. Of the most productive authors, 10 were mentioned as first author in 26.2% of publications (11/42) and the predominant institutions are based in the state of São Paulo. The term "trachoma" (n = 18) was the most recurrent keyword. CONCLUSION: This first scientometric analysis of research on trachoma in Brazil showed a limited number of studies on this disease. The scientific production slightly increased, although the origin of many studies is geographical areas with lower endemicity of this disease. Greater investments are needed for a better understanding and control of this neglected tropical disease. The analysis of bibliographic production on this topic is important to strengthen the development of research and strategic planning of programs for the control of trachoma and neglected tropical diseases in general.
