ABSTRACT Waste pickers constitute a marginalized demographic engaged in the collection of refuse, facing considerable occupational hazards that heighten their susceptibility to contract infectious diseases. Moreover, waste pickers contend with societal stigmatization and encounter barriers to accessing healthcare services. To explore the viral profile of waste pickers potentially linked to their occupational environment, we conducted a metagenomic analysis on 120 plasma specimens sampled from individuals employed at the Cidade Estrutural dumpsite in Brasilia city, Brazil. In total, 60 blood donors served as a comparative control group. Specimens were pooled and subjected to Illumina NextSeq 2000 sequencing. Viral abundance among waste pickers revealed the presence of significant pathogens, including HIV, HCV, and Chikungunya, which were not detected in the control group. Additionally, elevated levels of anelloviruses and Human pegivirus-1 were noted, with a comparable incidence in the control group. These findings underscore the utility of metagenomics in identifying clinically relevant viral agents within underserved populations. The implications of this study extend to informing public health policies aimed at surveilling infectious diseases among individuals facing socioeconomic disparities and limited access to healthcare resources. refuse Moreover services environment 12 city Brazil total 6 group 200 sequencing pathogens HIV HCV Chikungunya Additionally pegivirus1 pegivirus 1 pegivirus- noted populations resources 20 2

This study aimed to analyze the sociodemographic profile, risk factors and health conditions of elderly collectors of recyclable material who worked in an open-air garbage dump, the Structural City Dump in the Federal District, Brazil. The study is cross-sectional and data were collected from a semi-structured instrument, in which sociodemographic, epidemiological and laboratory variables of the research participants were analyzed. The survey demonstrates great vulnerability of this group, highlighting gender differences such as: 64.6% were women, 46.2% were single, 60% reported brown color, 26.2% had more than 4 children, 33.8% had no education level , 52.3 hypertensive and of these 61.9% were women; 83.1% reported exposure to risks with sharp piercing material and 61.5% to contact with decomposing garbage; 56.9% reported accidents with cuts and perforations; 70.8% contact with rodents; 83.1% reported exposure to smoke. This study suggests that the implementation of public and health policies are important to this group, as well as awareness strategies in society, in order to guarantee safe working and living conditions for the health of this population.

RESUMO O abastecimento público de água de maneira segura e eficiente ainda é um desafio no Brasil. Isso pode levar a um aumento na incidência de agravos como Doença Diarreica Aguda (DDA) e hepatite A. O objetivo deste trabalho foi associar a qualidade da água distribuída e a ocorrência de DDA e hepatite A no Distrito Federal (DF) (Brasil) entre 2012 e 2017. Os dados referentes aos índices de reclamação relativos à água e da não conformidade da sua qualidade foram cedidos pela Companhia de Abastecimento do DF. As taxas de ocorrência de DDA e hepatite A foram obtidos pela Secretaria de Saúde. Os índices de reclamação tiveram relação direta com os de não conformidades na concentração de cloro residual livre e de turbidez da água; no entanto, essa relação foi inversa aos agravos. Isso mostra que o monitoramento realizado pelo controle de qualidade da concessionária teve relevância na redução desses agravos, inclusive durante o período de intermitência no abastecimento (2017). O canal de comunicação entre os usuários e o prestador de serviços, portanto, foi fundamental para as ações corretivas da empresa, o que refletiu na redução de casos de DDA e de hepatite A.

ABSTRACT Safe and efficient public water supply is still a challenge in Brazil. This may lead to an increased incidence of diseases such as Acute Diarrheal Disease (ADD) and hepatitis A. The aim of this study was to associate the quality of water distributed and the occurrence of ADD and hepatitis A in the Federal District (FD) (Brazil) between 2012 and 2017. Data regarding the complaint rates related to water and the non-compliance of its quality were provided by the Supply Company of the FD. The occurrence rates of ADD and hepatitis A were obtained by the Department of Health. Complaint rates were directly related to the non-conformities in relation to free residual chlorine concentration and turbidity of water; however, that relation was inverse to the injuries. This shows that the monitoring carried out by the concessionaire's quality control was relevant in reducing these problems, even during the intermittent supply period (2017). Therefore, the communication channel between users and the service provider was fundamental for the company's corrective actions, which reflected in the reduction of ADD and hepatitis A cases.

Resumo O presente artigo analisou a forma de descarte de medicamentos pela população do Distrito Federal (DF), refletindo sobre seus possíveis riscos sanitários e ambientais. Para tanto, se realizou um estudo exploratório de corte transversal baseado em entrevistas com moradores das sete Unidades de Planejamento Territorial (UTP) do DF. Dentre os 393 entrevistados, 73,8% referiram possuir estoque de medicamentos no seu domicílio, 78,9% afirmaram já ter realizado o descarte de medicamentos sendo feitos, pela maioria, juntamente com os resíduos do tipo comum (73,6%). O descarte adequado esteve fortemente associado a maior escolaridade (p=0,027), maior classificação econômica (p=0,005), sexo masculino (p=0,006) e ao fato de ter recebido informação sobre o tema (p<0,001). Foi possível observar que o descarte inadequado de medicamentos é uma prática comum. O que suscita a necessidade da incorporação do tema em políticas específicas e em meios de comunicação.

Abstract This article has analyzed the drug disposal form by the population of Distrito Federal (DF), reflecting about its possible health and environmental risks. For that, an exploratory cross-sectional study was conducted based on interviews with residents of all Territorial Planning Units in DF. Among the 393 interviewees, 73.8% had a stock of medicines at home, 78.9% had already discarded drugs, which were mostly done in the common waste (73,6%). Adequate discharge was strongly associated with greater schooling (p = 0,027), higher economic classification (p = 0,005), male sex (p = 0,006) and with receiving information about the subject (p <0,001). It is noted that the inappropriate disposal of drugs is common. It presents the need to incorporate the theme into specific policies and media.

Resumen Este artículo muestra cómo la población del Distrito Federal (DF) se deshace de los medicamentos, teniendo en cuenta sus posibles riesgos medioambientales y de salud. Por lo tanto, llevamos a cabo un estudio exploratorio transversal basado en entrevistas con residentes de todas las Unidades de Planificación Territorial del Distrito Federal. Entre los 393 encuestados el 73,8% tenían un stock de medicamentos en sus hogares, el 78,9% realizó la eliminación de los medicamentos y el 73,6% lo hizo por medio de la basura. La eliminación adecuada está fuertemente asociada a la educación superior (p = 0,027), mayor estatus económico (p = 0,005), el sexo masculino (p = 0,006) y el hecho de haber recibido información sobre el tema (p <0,001). Se observa que la eliminación inadecuada de medicamentos es común. Suscita la necesidad de incorporar el tema de las políticas específicas y los medios de comunicación.

OBJECTIVES: The aim of this study was to evaluate the prevalence of enamel defects and their risk factors on primary and permanent dentitions of prematurely born children and full-term born children born at Regional Hospital of Asa Sul, Brasília, DF, Brazil. MATERIAL AND METHODS: Eighty 5-10-year-old children of both genders were examined, being 40 born prematurely (G1) and 40 born full term (G2). The demographic variables, medical history and oral health behaviors were retrieved using a questionnaire and data obtained from clinical examination were recorded. The teeth were examined and the presence of enamel defects was diagnosed according to the DDE Index and registered in odontograms. Subsequently, the defects were categorized in four groups according to one of the criteria proposed in 1992 by the FDI Commission on Oral Health, Research and Epidemiology. Kruskal-Wallis, Chi-square, Kappa, Mann-Whitney tests and logistic regression were used for statistical analysis. RESULTS: 75% of total sample had enamel defects. There was a major prevalence of hypoplasia of the enamel in G1 (p<0.001). There was a significant relationship between low weight and presence of the imperfections on the enamel in G1 on the primary dentition. The logistic regression model showed that the other risk factors such as monthly per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases were not associated with enamel defects and caries. CONCLUSIONS: Pre-term labor can be a predisposing factor for the presence of the enamel hypoplasia in the primary dentition.

This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1) and 40 born term (G2), in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth). The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95) was found in the group of premature children in comparison to the term children (2.07) p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926). One concludes that prematurity can't be a predisposing factor for the presence of dental caries.

O objetivo deste estudo foi avaliar a prevalência da cárie dentária em 192 crianças, 96 nascidas prematuramente e 96 a termo, em um hospital regional no Brasil. A média de idade ao exame clínico foi de 40,72 meses e 30,44 meses para os grupos a termo (G1) e prematuro (G2), respectivamente. As crianças foram divididas em faixas etárias de 0 a 3 e 4 a 6 anos. Os resultados estatísticos (testes t de Student e Kruskal-Wallis) mostraram que, entre 0 a 3 anos, o ceo-d foi 0,43 para o G1 e 0,01 para o G2. Entre 4 e 6 anos, o ceo-d foi 1,7 e 1,1 para G1 e G2, respectivamente. Os resultados foram significativos entre G1 e G2 apenas na faixa etária entre 0 e 3 anos (p = 0,047). A experiência de cárie mostrou que, das 96 crianças do G1, 75 estavam livres de cárie, enquanto que no G2, 84 não haviam tido a doença. Essas diferenças não foram significativas (p = 0,088). Conclui-se que o ceo-d médio menor encontrado no G2 entre 0 e 3 anos pode ser atribuído às freqüentes visitas de rotina e orientações sobre hábitos de higiene oral e dieta, oferecidos pela equipe de neonatologia. Após esta idade, com a dentição decídua completa, os valores aumentaram e se equipararam entre os grupos. Parece que o fenômeno de polarização esteve presente, visto que a experiência de cárie concentrou-se em um reduzido número de crianças.

The objective of this study was to evaluate the prevalence of dental caries in 192 children, 96 born prematurely and 96 at full term, in a regional hospital in Brazil. Mean age at clinical examination was 40.72 months in the full-term group (G1) and 30.44 months in the premature group (G2). The children were divided in two age subgroups: 0 to 3 and 4 to 6 years. Statistical results (Student's t and Kruskal-Wallis tests) showed that dmft was 0.43 for G1 and 0.01 for G2 in the 0-3 age subgroup, and 1.7 for G1 and 1.1 for G2 in the 4-6 age subgroup. Differences were significant between G1 and G2 only in the 0-3 age subgroup (p = 0.047). Caries evaluation showed that, of the 96 children in G1, 75 were caries free, while in G2, 84 did not have the disease. These differences were not significant (p = 0.088). The lower mean dmft found in the 0-3 age subgroup in G2 may be attributed to routines established by the hospital's neonatology staff, such as frequent dental visits and preventive instructions about oral habits, oral hygiene and diet. After this age, with the completion of the primary dentition, values increased and became similar between the G1 and G2 groups. Results also suggested a highly skewed distribution since most caries were found in only a small number of children.
