Spatiotemporal Evolution of the Yellow Fever Epidemic in Southeast Brazil from 2016 to 2019.

Background: Yellow fever (YF) is a zoonotic disease transmitted by mosquitoes among humans and nonhuman primates. Although urban YF is eradicated, the sylvatic YF has reemerged in some areas of Brazil in the twenty-first century. From 2016 to 2019, a sylvatic YF epidemic occurred in Southeast Brazil, where it had been eradicated in the 1940s. Methods: This study's objective was to describe the epidemic in the states of the Southeast region, based on descriptive, cluster, and mobility analyses. Results: Both the descriptive and cluster analyses showed that the YF cases spread from the state of Minas Gerais southward, causing peaks in cases during the summer months. None of the state capitals was included in the clusters, but the connectivity between the municipalities in Greater Metropolitan São Paulo highlighted potential paths of spread. Despite differences in sociodemographic profiles between the Southeast and North of Brazil (the latter region considered endemic), the epidemiological profile was similar, except for patients' occupation, which was not related to rural work in the Southeast. Conclusion: The results contributed to our understanding of the paths by which YF spread across Southeast Brazil and the epidemiological profile in an area that had gone decades without autochthonous cases.

Addressing discrimination and violence against Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) persons from Brazil: a mobile health intervention.

BACKGROUND: Sexual and gender minorities (SGM) experience higher rates of discrimination and violence when compared to cis, heterosexual peers. However, violent crimes and other hate incidents against SGM persons are consistently not reported and prosecuted because of chronic distrust between the SGM community and police. Brazil is one of the most dangerous countries for SGM persons globally. Herein, we describe the development of a mobile health intervention to address the rampant violence against this population, the Rainbow Resistance-Dandarah app. METHODS: We conducted community-based participatory research (CBPR) between 2019 and 2020. The study started with in-depth interviews (IDIs) and focus group discussions (FGDs) with representatives of the SGM community from Brazil. Descriptive qualitative data analysis included the plotting of a 'word cloud', to visually represent word frequency, data coding and analysis of more frequent themes related to app acceptability, usability, and feasibility. A sub-sample of SGM tested the app and suggested improvements, and the final version was launched in December 2019. RESULTS: Since the app was launched in December 2019, the app recorded 4,114 active SGM users. Most participants are cisgender men (50.9%), self-identified as gay (43.5%), White (47.3%), and aged 29 or less (60.9%). FGDs and IDIs participants discussed the importance of the app in the context of widespread violence toward SGM persons. Study participants perceived this mHealth strategy as an important, effective, and accessible for SGM surviving violence. The CBPR design was highlighted as a key strategy that allowed SGM persons to collaborate in the design of this intervention actively. Some users reported how the panic button saved their lives during violent attacks. CONCLUSIONS: Rainbow Resistance-Dandarah app was endorsed as a powerful tool for enhancing reporting episodes of violence/discrimination against SGM persons and a key strategy to connect users with a safe network of supportive services. Results indicate that the app is an engaging, acceptable, and potentially effective mHealth intervention. Participants reported many advantages of using it, such as being able to report harassment and violence, connect with a safe network and receive immediate support.

Analysis of age, period, and birth cohort effects on suicide mortality in Brazil and the five major geographic regions.

OBJECTIVE: Estimate the effects of age, period, and birth cohort on suicide mortality in Brazil by major geographic region in the overall population and by sex. METHODS: This was a time trend ecological study. National and regional suicide mortality data from 1981 to 2020 were analyzed for the overall population and by sex. Age, period, and cohort effects were calculated with a Poisson regression model using estimable functions with the Epi package of the R statistical program, version 4.2.1. RESULTS: There were 272,716 suicides in individuals ranging from 20 to 79 years old. In the overall population, the age model-adjusted suicide mortality rates showed an upward pattern for Brazil. The most recent cohort showed the highest associated risk, 1.67 (95%CI 1.63; 1.71), while for the reference period, it was the highest risk among all the periods. CONCLUSIONS: Suicide mortality rates have shown an upward trend with advancing age in both men and women in the Brazilian population. However, the behavior of the period effect and cohort depends on the population analyzed and regional distribution.

The Dandarah App: An mHealth Platform to Tackle Violence and Discrimination of Sexual and Gender Minority Persons Living in Brazil.

Discrimination and violence are widely experienced by sexual and gender minority (SGM) persons worldwide. More than one SGM person is murdered every day in Brazil because of their sexuality or gender identity, which is the highest reported homicide rate in the world. Alt-hough discrimination and violence against SGM persons in Brazil are considered to be hate crimes, reporting is still suboptimal due to fear of police SGM phobia and victim blaming. Accessible and easily disseminated interventions are urgently needed. Herein, we describe the develop-ment of an mHealth solution to help address violence against SGM persons, namely the Rainbow Resistance: Dandarah App, with a synthesis of key results and feedback from the SGM community after 24 months of using the app. Twenty-two focus group discussions (FGDs) were conducted with SGM persons living in six Brazilian states: Bahia, Federal District, São Paulo, Rio de Janeiro, Minas Gerais, Sergipe, and Pará. A total of 300 SGM persons participated in the FGDs. A thematic analysis was performed to interpret the qualitative data. Content themes related to aesthetics, us-ability, barriers to resources, and likes/dislikes about the intervention arose from the FGDs. Participants found the intervention to be user-friendly, endorsed more likes than dislikes, and suggested a few changes to the app. The findings suggest that the intervention is usable and fit for future ef-fectiveness testing, and that it could fill an important gap in the well-being of SGM persons living in a country with high levels of discrimination and violence towards this community, i.e., Brazil.

[Behavioral changes in smokers after implementation of anti-smoking legislation in ArgentinaMudança de comportamento nos fumantes após a implementação da legislação antifumo na Argentina]. / Cambio de comportamiento en personas fumadoras posimplementación de legislación antitabaco en Argentina.

OBJECTIVE: Identify factors related to behavioral changes in smokers over 18 years of age following implementation of provincial policies for 100% smoke-free spaces in Argentina. METHODS: A cross-sectional analytical study was conducted. The multilevel technique was used with data from different hierarchies. Secondary data sources were used: National Risk Factor Surveys 2005, 2009, and 2013. RESULTS: The individual analysis of explanatory variables revealed that residents of provinces that do not have smoke-free legislation were 40% less likely to consider quitting smoking than people who live in provinces with such legislation. In provinces without smoke-free spaces, males over 65 years old are even less likely to think about quitting smoking. CONCLUSIONS: The results suggest that legislation based on Article 8 of the Framework Convention would be effective in promoting tobacco cessation in Argentina.

OBJETIVO: Identificar os fatores associados à mudança de comportamento nos fumantes maiores de 18 anos após a implementação de políticas provinciais de proibição do fumo na Argentina. MÉTODOS: Foi realizado um estudo analítico de corte transversal. Foi usada uma técnica de modelos multiníveis com dados de diferentes hierarquias. As fontes de dados secundários consultadas foram as iterações de 2005, 2009 e 2013 da Pesquisa Nacional de Fatores de Risco. RESULTADOS: Na análise individual das variáveis explicativas, verificou-se que os habitantes das províncias sem legislação antifumo tinham uma probabilidade 40% maior de não considerar parar de fumar quando comparados aos moradores das províncias com legislação antifumo. Em comparação às províncias com legislação antifumo, nas províncias sem esta legislação, ser do sexo masculino e ter idade acima de 65 anos foram as características associadas a uma maior chance de não considerar parar de fumar. CONCLUSÕES: Os resultados do estudo indicam que uma legislação em conformidade com o Artigo 8 da Convenção-Quadro para o Controle do Tabaco da OMS seria efetiva para incentivar as pessoas a pararem de fumar na Argentina.

Epidemiology of dermatophytoses in 31 municipalities of the province of Buenos Aires, Argentina: A 6-year study / Epidemiología de las dermatofitosis en 31 municipios de la provincia de Buenos Aires, Argentina: estudio de 6 años

Background: No reliable data are available in the province of Buenos Aires regarding the frequency of dermatophytoses and other fungal diseases. The distribution of the clinical forms and the species involved are also unknown. Aims: To present the data collected by the laboratories participating in the Mycology Network of the province of Buenos Aires (MNPBA) from a retrospective epidemiological survey on dermatophytoses. Methods: A descriptive and exploratory analysis was performed on the cases of dermatophytoses gathered between 2002 and 2007 by the Mycology Network of the province of Buenos Aires. Results: Of the 3966 dermatophytosis cases reported by 41 laboratories in 31 municipalities, more than a half occurred in three highly populated urban municipalities. The male:female ratio was 1:1.5. The most frequent clinical form was tinea unguium, diagnosed in 904 cases (51.83%), followed by tinea capitis (19.32%), tinea corporis (15.19%), tinea pedis (6.77%), tinea cruris (3.73%), and tinea manuum (2.18%). The species involved was identified in 1368 (33.49%) cases. Trichophyton rubrum was the most common species, with a frequency of 42.03%. An association was found between urban municipalities and T. rubrum or the Trichophyton mentagrophytes complex. Conclusions: Results from the MNPBA survey provide valuable information that should enable further interventions to be designed in order to prevent and control the disease

Determinants of homicides in the state of Bahia, Brazil, in 2009.

PURPOSE: To carry out a study of association between socioeconomic and demographic factors and homicides in general population, in the state of Bahia, in 2009. METHODS: This is an ecological study. The data were collected from the database of the Information System about Mortality of the Ministry of Health, from the Brazilian Institute of Geography and Statistics and the Institute of Applied Economic Research. The Global Moran index was calculated for the detection of spatial autocorrelation, and the Local Moran index was calculated for the detection of spatial Clusters. The transformation in the variable answer (homicides rates) was performed and it was shaped using the Conditional Autoregressive Model. RESULTS: The data showed spatial autocorrelation. Two clusters of municipalities with high rates of homicides were identified, one located predominantly in the Greater Metropolitan Region of Salvador and the other in the South Region of Bahia, especially Eunápolis and Lauro de Freitas, which had the highest rates. The Average Residents Variables, local GDP and the Percentage of Illiteracy presented an inverse association with homicide rates, and the variables Firjan's municipal development index of work and income. Enrolment in high school and the Average of Bolsa Família were directly associated. CONCLUSIONS: The urbanization process, in most cases, not controlled by the State, in most cases, made the cities bigger and with better socioeconomic conditions, attraction centers for people with different socioeconomic levels, increasing the social inequality among the residents of these regions, with parallel increase in homicide rates.

Are resilience and maternal sense of coherence associated with gingival status in adolescents from low-income families?

BACKGROUND: The capacity to overcome social disadvantages and maintain oral health through psychosocial processes remains poorly understood in children. AIM: This study assessed the relationship of children's resilience and maternal sense of coherence (SOC) with gingival status in children from low-income families. METHODS: A cross-sectional study was conducted on 190 schoolchildren aged 11-12 years and their mothers. Family socioeconomic characteristics and housing conditions, maternal and children's oral cleanliness behaviours (tooth brushing and dental floss use), maternal SOC, children's resilience, and demographic data were collected through interviews with children and their mothers. Validated versions of Antonovsky's scale and the resilience scale were used to assess mother's SOC and children's resilience. Gingival status and dental plaque of children were evaluated through clinical examinations using bleeding on probing index and plaque index. Statistical analysis included Pearson's correlation and hierarchical multinomial ordinal logistic regression analyses. RESULTS: The mean frequency of gingival bleeding in the sample was 8.4% (SD: 8.5). Children with higher levels of resilience showed 31% lower odds of gingival bleeding (OR: 0.7; 95% CI: 0.4-0.9) after adjustment for socioeconomic characteristics, children's and mothers' use of dental floss. CONCLUSIONS: Children's resilience was a psychosocial factor associated with gingival conditions.

Association between family environment and attention deficit hyperactivity disorder in children--mothers' and teachers' views.

BACKGROUND: To ascertain whether factors of the family environment and gestational period are associated with the appearance of ADHD in children, as reported by various different informants (mothers and teachers). METHODS: This paper presents results from the dataset of a longitudinal study to evaluate behavioral problems among schoolchildren in São Gonçalo, Rio de Janeiro State, in 2005 and 2006. The cross-section considered for this paper comprises records of exposure factors and ADHD. In all, 370 schoolchildren of the public school system were assessed by 3-stage cluster sampling. The Child Behavior Checklist (CBCL) and the Teacher Report Form (TRF) were used to measure outcomes. The exposure factors examined were: profile of child and mother, variables relating to the family environment, and perinatal considerations. The questions were answered by mothers and teachers. A hierarchical logistic regression model was used. RESULTS: Precariously functioning families, lack of social support for mothers, adverse life events and discord during pregnancy were the factors associated with mother-reported ADHD. When ADHD was reported by teachers, the variables selected were: Intelligence quotient (IQ) and sex, with children with low IQ scores and boys more likely to display the disorder. CONCLUSIONS: Assessment of ADHD by teachers or mothers reveals specific characteristics that reflect how each of these informants understands the children. This highlights the importance of using informants from different environments in diagnosing the disorder.

Violence and injuries in Brazil: the effect, progress made, and challenges ahead.

Although there are signs of decline, homicides and traffic-related injuries and deaths in Brazil account for almost two-thirds of all deaths from external causes. In 2007, the homicide rate was 26·8 per 100,000 people and traffic-related mortality was 23·5 per 100,000. Domestic violence might not lead to as many deaths, but its share of violence-related morbidity is large. These are important public health problems that lead to enormous individual and collective costs. Young, black, and poor men are the main victims and perpetrators of community violence, whereas poor black women and children are the main victims of domestic violence. Regional differentials are also substantial. Besides the sociocultural determinants, much of the violence in Brazil has been associated with the misuse of alcohol and illicit drugs, and the wide availability of firearms. The high traffic-related morbidity and mortality in Brazil have been linked to the chosen model for the transport system that has given priority to roads and private-car use without offering adequate infrastructure. The system is often poorly equipped to deal with violations of traffic rules. In response to the major problems of violence and injuries, Brazil has greatly advanced in terms of legislation and action plans. The main challenge is to assess these advances to identify, extend, integrate, and continue the successful ones.

Ecological analysis of the relationship between infant mortality and cardiovascular disease mortality at ages 45-69 in the Brazilian 1935 birth cohort.

BACKGROUND: International ecological studies have shown a positive association between infant mortality as a proxy for low birth weight and cardiovascular disease mortality in adult life. METHODS: Mortality rates due to Cardiovascular Diseases (CVDMR) standardised by age in adults between 45 and 69 years of age and by place of birth (pob) and residence (res) were related to Infant Mortality Rates (IMR) in the Brazilian 1935 birth cohort. RESULTS: Two relationship patterns were noted between IMR and CVDMR: for the Southeast, South and Centre-West group of regions (r(pob)=0.46; r(res)=0.29) and for the North and Northeast group of regions (r(pob)=0.21; r(res)=0.33). For the latter pattern, two states were identified (Rio Grande do Norte and Paraíba) as atypical areas, whose exclusion strengthened the association (r(pob)=0.73; r(res)=0.91). CONCLUSIONS: The direction of the associations changed after the analysis by group of Brazilian regions (indirect control of socio-economic levels, coverage and quality of the information). There is a positive, although weak association between IMR and CVDMR. Attempts to control or minimise the interference of migratory movements, cohort effects and socio-economic levels represented methodological progress in ecological analyses of foetal programming in Brazil.
