Abstract
Immunization programs worldwide have been facing challenges in keeping vaccination coverage high. Even though universally known for its robust National Immunization Program, Brazil has also faced significant challenges regarding vaccination coverage. One of the reasons for this is vaccine hesitancy, a complex, multi-causal, and context-specific phenomenon. This qualitative study aims to understand the factors associated with decision-making and the drivers of vaccine hesitancy in Florianopolis, Santa Catarina state capital, regarding caregivers' perceptions of routine childhood vaccination. In-depth interviews were conducted in the Capital city of Santa Catarina State. Families with children up to 6 years old were included. Data were analyzed based on thematic content analysis. Twenty-nine caregivers in 18 families were interviewed. These caregivers were mainly mothers and fathers. Three themes emerged: 1. Access to information and the decision-making process, where we discuss the role of social circles, healthcare workers, and the internet; 2. Individual-institutions power relationships: Perceptions about the State's role and the Health institutions: 3. Reasons and motivations: The senses and meanings behind non-vaccination, where we discuss the drivers of vaccine hesitancy related to risk perception, caregivers' opinions on the medical-pharmaceutical industry, vaccines' composition and their side effects, families' lifestyles and worldviews, and the childhood routine vaccination schedule. The results of this study reaffirm the complexity of the decision-making process in childhood vaccination and further enable a better contextual understanding of the complex and challenging phenomenon of vaccine hesitancy.

Abstract
Despite the importance of fish-borne trematodes of the family Opisthorchiidae as causative agents of human liver fluke disease, studies on these parasites outside Asia are relativally scarce. In South America, human focus of amphimerosis is known in Ecuador since the mid-20th century, and Amphimerus spp. have also been reported in wild and domestic mammals. Nevertheless, the knowledge on the snails that act as the first intermediate host of these potentially zoonotic parasites are scarce. Herein, a new cercaria of the pleurolophocercous morphotype found in the freshwater snail Idiopyrgus souleyetianus from Brazil was subjected to morphological and molecular studies. Multigene phylogenetic analyses based on 28S, 5.8S-ITS-2 and Cox-1 sequences enabled the identification of Amphimerus sp., a species distinct from that reported in humans from Ecuador. This cercariae was morphologically compared with other opisthorchiid cercariae known. The possible occurrence of human amphimerosis in Brazil is discussed.

Abstract
This study comprehensively analyzed cases of scorpion envenomation in Brazil, exploring the temporal trends and geographic patterns of such incidents between January 1, 2012, and December 31, 2022. Simultaneously, we assessed the correlation between scorpion envenomation and social determinants of health and social vulnerability. We conducted a population-based ecological study, gathering information on the number of scorpion envenomation cases in Brazil, as well as socioeconomic data and social vulnerability indicators across the 5,570 Brazilian municipalities. The season-trend model, based on the classical additive decomposition method, informed estimations of scorpion envenomation variations over time. The spatial correlation of scorpion envenomation with socioeconomic and vulnerability indicators was assessed using the Bivariate Moran's I. A total of 1,343,224 cases of scorpion envenomation were recorded in Brazil from Jan 2012 to Dec 2022. A single increasing time trend was observed for the entire country for this period (APC 8.94, P < 0.001). The seasonal analysis was significant for Brazil as a whole and all regions (p < 0.001), with peaks evident between October and November. The spatial distribution of cases was heterogeneous, with spatial clusters concentrated in the high-risk Southeast and Northeast regions. There was a high incidence of scorpion envenomation in municipalities facing social vulnerability, and, paradoxically, in those with better sanitation and waste collection. Our study revealed a heterogeneous geographical distribution of scorpion accidents in Brazil. Municipalities with higher social vulnerability exhibited a high incidence of scorpion envenomation.

Abstract
Studies have identified elevated levels of mercury in Amazonian Indigenous individuals, highlighting them as one of the most exposed to risks. In the unique context of the Brazilian Indigenous population, it is crucial to identify genetic variants with clinical significance to better understand vulnerability to mercury and its adverse effects. Currently, there is a lack of research on the broader genomic profile of Indigenous people, particularly those from the Amazon region, concerning mercury contamination. Therefore, the aim of this study was to assess the genomic profile related to the processes of mercury absorption, distribution, metabolism, and excretion in 64 Indigenous individuals from the Brazilian Amazon. We aimed to determine whether these individuals exhibit a higher susceptibility to mercury exposure. Our study identified three high-impact variants (GSTA1 rs1051775, GSTM1 rs1183423000, and rs1241704212), with the latter two showing a higher frequency in the study population compared to global populations. Additionally, we discovered seven new variants with modifier impact and a genomic profile different from the worldwide populations. These genetic variants may predispose the study population to more harmful mercury exposure compared to global populations. As the first study to analyze broader genomics of mercury metabolism pathways in Brazilian Amazonian Amerindians, we emphasize that our research aims to contribute to public policies by utilizing genomic investigation as a method to identify populations with a heightened susceptibility to mercury exposure.

Abstract
Rhodolith beds are known worldwide to host high biodiversity to several taxa. Despite their importance, few ecological data explored the influence of rhodolith features and environmental variables on associated biodiversity, a gap that has been hampering the mapping of diversity hotspots and priority areas for conservation. In this study, we investigated large-scale spatial variations of rhodolith beds and their associated fauna, using annelid polychaetes as a biological model. We aimed to identify proxies, based on rhodolith features and environmental variables, to detect biodiversity hotspots across Southwestern Atlantic beds, laying the groundwork for mapping priority areas for conservation. With this goal, we sampled a total of 136 rhodolith nodules across seven sites with beds under distinct latitudes, depths, distances from the mainland coast of Brazil, and rhodolith densities. For each nodule sampled, we measured the volume, diameter, and mass of sediment trapped, as well as the attributes of the associated polychaetes (abundance, richness, diversity, and composition). Our results revealed a complex network of collinearities and synergisms between the rhodolith features and the majority of the polychaetes attributes (i.e., abundance, diversity, and composition). Polychaete richness, in contrast, can be explained by the combination of two proxies: (1) rhodolith nodule diameter and (2) distance of the rhodolith bed from the mainland coast. Nearshore rhodolith beds and larger nodules were associated with higher values of richness. Additionally, rhodoliths with a hollow morphology were also associated with higher values of polychaete richness. These results suggest that nearshore rhodolith beds with large and hollow nodules could be priority areas for conservation. However, further multi-taxa studies using our framework are still needed to explore other regions and scales, delineating more comprehensive proxies for predicting ecological patterns of the rhodoliths associated fauna and to identify priorities for conservation across Southwestern Atlantic beds.

Abstract
Community Health Worker (CHW) home visits are central to primary care provision in São Paulo, Brazil. Yet CHWs receive little training prior to conducting these visits. In the neighborhood where I conducted ethnographic fieldwork, nearly half of patients were immigrants to Brazil, adding a layer of sociocultural and linguistic difference. I thus investigated how interactions between CHWs and patients unfolded and were shaped by cultural processes. Analyzing fieldnotes and interview data, I found that CHWs cherished relationships with older adult Portuguese-speaking patients, while expressing exasperation and even disgust with more recent immigrants and patients living with stigmatized health conditions. The cultural processes of recognition and stigma shaped CHWs' perceptions of and interactions with patients. I ground these analyses in the history of state-sponsored discourse linking immigrants with poor hygiene, concluding that home visits deserve greater scrutiny as a public health tool that may increase access to care at the expense of health equity.

Abstract
OBJECTIVES The aim of this study was to estimate smoking-attributable mortality (SAM) in the population aged 35 years and over in Brazil's 27 federal units by sex, in 2019. STUDY DESIGN This is an attributable mortality analysis. METHODS We applied a method dependent on the prevalence of smoking, based on the population attributable fractions. Data on mortality due to causes causally related to smoking were derived from Brazil's Death Registry, data on prevalence of smoking from a survey conducted in Brazil in 2019, and data on relative risks from five US cohorts. Crude and age-adjusted SAM rates were calculated by sex. Estimates of SAM were calculated by specific causes of death and major mortality groups for each federal unit by sex. RESULTS In 2019, smoking caused 480 deaths per day in Brazil. Although the SAM varied among the federal units, the pattern is not clear, with the greatest difference being between Rio Grande do Sul (crude rate: 248.8/100,000 inhabitants) and Amazonas (106.0/100,000). When the rates were adjusted by age, the greatest differences were observed between Acre (271.1/100,000) and Distrito Federal (131.1/100,000). SAM was higher in males; however, while the main specific cause of SAM in men was ischemic heart disease, in women it was chronic obstructive pulmonary disease. The major mortality group having the greatest impact on SAM across all federal units was the cardiometabolic diseases. CONCLUSIONS The variability in the burden of SAM in the different regions of Brazil reaffirms the need for SAM data disaggregated at the geographic level.

Abstract
Proterochampsidae is a clade of non-archosaurian archosauriforms restricted to the Middle to the Late Triassic of the Ischigualasto-Villa Unión Basin of Argentina and the Santa Maria Supersequence of Brazil. A reappraisal of proterochampsid specimens from the Brazilian Dinodontosaurus Assemblage Zone (AZ) of the Pinheiros-Chiniquá Sequence (late Ladinian-early Carnian) is presented here. One of the specimens was preliminary assigned to Chanaresuchus sp., whose type species comes from the Massetognathus-Chanaresuchus AZ of the Chañares Formation of Argentina. However, our revision indicates that it differs from Chanaresuchus, being more closely related to the middle-late Carnian Rhadinosuchus gracilis. We therefore propose the new taxon, Pinheirochampsa rodriguesi, to reallocate this specimen. Additionally, we present a revision of other putative Chanaresuchus occurrences in Brazil, including the only known specimen described for the Santacruzodon AZ (Santa Cruz do Sul Sequence; early Carnian), also proposing it as a new taxon: Kuruxuchampsa dornellesi. Both new species are characterized, among other features, by transverse expansion of the anterior end of the rostrum, similar to the condition present in Rhadinosuchus, but absent in Chanaresuchus, Gualosuchus, Pseudochampsa, and non-rhadinosuchine proterochampsids. These two new species expand the growing knowledge of the non-archosaurian archosauriform diversity during the Middle-Late Triassic in South America and enhance faunal and chronological comparisons between approximately coeval geological units between Argentina and Brazil.

Abstract
OBJECTIVE The objective was to evaluate the psychometric properties of the Mindful Eating Questionnaire (MEQ) in Brazilian subjects with type 2 diabetes mellitus (T2DM) and validate a Brazilian version of the MEQ for adults with T2DM (MEQ-DM). METHODOLOGY Baseline data from the multicentre Nutritional Strategy for Glycaemic Control in Patients with Type 2 Diabetes Mellitus (NUGLIC) trial were used. Construct validity was assessed using exploratory factor analysis (EFA). The root mean square error of approximation (RMSEA), comparative fit index (CFI) and Tucker‒Lewis index (TLI) fit indices indicated the adequacy of the model. The reliability of the questionnaire was evaluated considering the different factor loadings. Criterion validity was tested by correlating the MEQ-DM with sociodemographic variables, body mass index (BMI) and physical activity levels. RESULTS A total of 370 participants were included, who were mostly female (60.8 %) and had a median age of 61 (54-67) years. The EFA results supported the two-factor structure of the 25-item MEQ-DM: disinhibition and awareness. The results of the fit indices (RMSEA = 0.04; CFI = 0.95 and TLI = 0.94) and composite reliability (disinhibition = 0.84 and awareness = 0.81) were consistent. The criterion validity analysis indicated a significant association between MEQ-DM scores and age, sex, civil status, education level, BMI and physical activity (p < 0.05). CONCLUSION When explored with Brazilian adults with T2DM, the MEQ-DM presented a factorial model with two dimensions: disinhibition and awareness. This model must be confirmed in future studies with Brazilians with T2DM.

Abstract
Microplastics (MPs) accumulation in rocky shore organisms has limited knowledge. This study investigated MPs accumulation in filter-feeding oysters, herbivorous limpets and carnivorous snails to assess their performance as sentinel species in the MPs trophic transfer. The samples were obtained along a contamination gradient in the Santos Estuarine System, Brazil. All three studied species showed MPs concentrations related to the contamination gradient, being the oysters the species that showed the highest levels, followed by limpets and snails (average of less and most contaminated sites of 1.06-8.90, 2.28-5.69 and 0.44-2.10 MP g-1, respectively), suggesting that MPs ingestion rates are linked to feeding habits. MPs were mainly polystyrene and polyacetal. The polymer types did not vary among sites nor species. Despite minor differences in percentages and diversity of size, shape, and color classes, the analyzed species were equally able to demonstrate dominance of small, fiber, transparent, black and blue MPs. Thus, oysters, limpets, and snails are proposed as sentinels of MPs in monitoring assessments.

Abstract
OBJECTIVES The objective of this study was to analyse the global burden of disease attributable to undernutrition and high body mass index (BMI) in Brazil and its 27 states, as well as its association with the socio-demographic index (SDI) from 1990 to 2019. STUDY DESIGN This is an epidemiological time-series study. METHODS This study analysed the undernutrition and high BMI estimated by the Global Burden of Disease study conducted from 1990 to 2019 for Brazil and its states, using the following metrics: absolute number of deaths, standardised mortality rate, and disability-adjusted life years (DALYs). This study also analysed the correlation between the percentage variation of mortality rates and SDI. RESULTS A decrease in the number of deaths (-75 %), mortality rate (-75.1 %), and DALYS (-72 %) attributable to undernutrition was found in Brazil and in all regions. As regarding the high BMI, an increase in the number of deaths was found (139.6 %); however, the mortality rate (-9.7) and DALYs (-6.4 %) declined in all regions, except in the North and Northeast regions, which showed an increase. A strong correlation was identified between undernutrition and high BMI with SDI. CONCLUSION Our study observed a double burden of malnutrition in Brazil, with a reduction in the burden of diseases due to malnutrition in Brazil and variation in the burden due to high BMI according to the socioeconomic status of the region. Public policies are necessary in order to guarantee the human right to a healthy and sustainable diet, together with food and nutrition security and a diminishing of social inequality.

Abstract
Buriolestes schultzi is a small sauropodomorph dinosaur from Carnian beds (ca., 233 Ma) of southern Brazil. It is one of the earliest members of that lineage and is a key taxon to investigate the initial evolution of Sauropodomorpha. Here, we attribute a new specimen to B. schultzi from Late Triassic of southern Brazil, which represents the first occurrence of the taxon outside the type locality. The new specimen comprises a disarticulated and partial skeleton, including cranial and postcranial elements. It is tentatively regarded as an additional specimen of B. schultzi according to a unique combination of traits (including autapomorphies). Conversely, the new specimen is stouter than the other specimens of B. schultzi, as shown by femoral Robustness Index. Based on femoral circumference, the estimated body mass of the new specimen is approximately 15 kg, which is far higher than the previous estimations for other specimens of B. schultzi (i.e., approximately 7 kg). In fact, the new specimen and some specimens of Eoraptor lunensis and Saturnalia tupiniquim were found to be significantly stouter than coeval sauropodomorphs. Therefore, instead of all being constructed as gracile, the earliest sauropodomorphs experienced an unappreciated intraspecific variation in robustness. This is interesting because more precise data on species body mass are crucial in order to better understand the complex terrestrial ecosystems in which dinosaurs originated.

Abstract
OBJECTIVES This study aimed to compare the uptake, reasons for discontinuation, continuation, and satisfaction of long-acting contraceptive methods (LARC) when offered at no cost in Campinas, Brazil. STUDY DESIGN This was a prospective cohort study conducted at University of Campinas, Campinas, São Paulo, Brazil, including women aged 18 to 48 years, who adopted one of three methods. Participants underwent telephone follow-up every 3 months for up to 24 months after insertion. Satisfaction was assessed at the end of 2 years of use through the Likert scale. RESULTS We invited 1222 women, and among the 971 women who volunteered to participate in follow-up, 414 (42.6%) chose the levonorgestrel 52-mg intrauterine device (IUD), 358 (36.9%) chose the etonogestrel (ENG) implant, and 199 (20.5%) chose the TCu380A IUD. Discontinuation due to bothersome bleeding was higher among users of the ENG implant (10/358; 2.4%) and the TCu380A IUD (32/199; 8.9%), and expulsion was higher for the TCu380A IUD (30/199; 15.1%). Women continued at 24 months were 340/414 (82.1%), 270/358 (75.4%), and 119/199 (59.8%) among users of the levonorgestrel 52-mg IUD, ENG implant, and TCu380A IUD, respectively. The users of the levonorgestrel 52-mg IUD (301/339, 88.8%), the ENG-implant (222/270, 82.2%), and the TCu380A IUD (105/119, 88.2%) were satisfied or very satisfied by 24 months of follow-up. CONCLUSIONS The three LARC methods had great uptake, high continuation, and discontinuation due to bothersome bleeding was higher among users of the ENG implant and the TCu380A IUD, and expulsion was higher for the TCu380A IUD compared to the 52-mg levonorgestrel IUD. Most of the participants reported being very satisfied. IMPLICATIONS When the LARC methods were offered at no cost in a Brazilian public clinic the uptake, satisfaction and continuation were high by 24 months after device placement, and high level of satisfaction was reported by most of the participants.

Abstract
Feline parvovirus (FPV) and canine parvovirus (CPV) are over 98% identical in their DNA sequences, and the new variants of CPV (2a/2b/2c) have gained the ability to infect and replicate in cats. The aim of this study was to determine the genetic diversity in the VP2 gene of parvovirus strains circulating in domestic cats in Brazil during a 10-year period (2008-2017). For parvovirus screening, specific PCR was performed, and 25 (34.7%) of 72 cats tested positive. The PCR-positive samples were further subjected to full-length VP2 sequencing (1755 bp), and eight sequences (36%) were characterized as FPV, seven (28%) as CPV-2a and (32%) nine (36%) as CPV-2b. One sequence (RJ1085/11) showing typical CPV amino acid (aa) at residues 80 R, 93 N, 103 A, 232 I, and 323 N could not be characterized at this time. The sequences in this study displayed aa changes previously described for FPV (A14T, A91S, I101T, N564S, and A568G) from cats and CPV-2a/2b (S297N and Y324L) from dogs. However, the Y324L mutation has not yet been reported in any CPV-2a/2b strains from cats. Phylogenetic analysis supported the division of these sequences into two well-defined clades, clade 1 for FPV and clade 2 for CPV2a/2b. Unusually, the sequence RJ1085/11 was grouped separately. Two recombination breakpoints were detected by Bootscan and 3Seq methods implemented in the RDP4. This study is the first report of CPV-2a/2b in cats in Brazil. The detection of FPV strains with mutations characteristic of CPV indicates that Brazilian FPV strains have undergone genetic changes.

Abstract
The COVID-19 pandemic has brought the epidemiological value of monitoring wastewater into sharp focus. The challenges of implementing and optimising wastewater monitoring vary significantly from one region to another, often due to the array of different wastewater systems around the globe, as well as the availability of resources to undertake the required analyses (e.g. laboratory infrastructure and expertise). Here we reflect on the local and shared challenges of implementing a SARS-CoV-2 monitoring programme in two geographically and socio-economically distinct regions, São Paulo state (Brazil) and Wales (UK), focusing on design, laboratory methods and data analysis, and identifying potential guiding principles for wastewater surveillance fit for the 21st century. Our results highlight the historical nature of region-specific challenges to the implementation of wastewater surveillance, including previous experience of using wastewater surveillance, stakeholders involved, and nature of wastewater infrastructure. Building on those challenges, we then highlight what an ideal programme would look like if restrictions such as resource were not a constraint. Finally, we demonstrate the value of bringing multidisciplinary skills and international networks together for effective wastewater surveillance.

Abstract
The mechanisms underlying racial inequities in uncontrolled hypertension have been limited to individual factors. We investigated racial inequities in uncontrolled hypertension and the explanatory role of economic segregation in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). All 3897 baseline participants with hypertension (2008-2010) were included. Uncontrolled hypertension (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg), self-reported race (White/Brown/Black people), and neighborhood economic segregation (low/medium/high) were analyzed cross-sectionally. We used decomposition analysis, which describes how much a disparity would change (disparity reduction; explained portion) and remain (disparity residual; unexplained portion) upon removing racial differences in economic segregation (i.e., if Black people had the distribution of segregation of White people, how much we would expect uncontrolled hypertension to decrease among Black people). Age- and gender-adjusted prevalence of uncontrolled hypertension (39.0%, 52.6%, and 54.2% for White, Brown, and Black participants, respectively) remained higher for Black and Brown vs White participants, regardless of economic segregation. Uncontrolled hypertension showed a dose-response pattern with increasing segregation levels for White but not for Black and Brown participants. After adjusting for age, gender, education, and study center, unexplained portion (disparity residual) of race on uncontrolled hypertension was 18.2% (95% CI 13.4%; 22.9%) for Black vs White participants and 12.6% (8.2%; 17.1%) for Brown vs White participants. However, explained portion (disparity reduction) through economic segregation was - 2.1% (- 5.1%; 1.3%) for Black vs White and 0.5% (- 1.7%; 2.8%) for Brown vs White participants. Although uncontrolled hypertension was greater for Black and Brown vs White people, racial inequities in uncontrolled hypertension were not explained by economic segregation.

Abstract
Background Identifying modifiable risk factors for child victimisation and polyvictimisation (exposure to multiple types of victimisation) is critical for informing prevention efforts, yet little evidence is available in low- and middle-income countries. The authors aimed to estimate the prevalence of child victimisation and polyvictimisation, and examine unique and shared risk factors in a population-based cohort in Southern Brazil. Methods Lifetime child victimisation was based on maternal report when children were aged 4 years old (N∼3900) and included five types of victimisation (conventional crime, child maltreatment, peer/sibling victimisation, sexual victimisation, and witnessing/indirect victimisation) and polyvictimisation. Based on a socioecological model, possible risk factors were examined in four levels: community, maternal and family, parent, and child. Findings Conventional crime and peer/sibling victimisation were the most common types of victimisation (46.0 and 46.5%, respectively), followed by witnessing/indirect victimisation (27.0%), and child maltreatment (11.3%). Sexual victimisation had the lowest prevalence (1.4%). One in 10 (10.1%) children experienced polyvictimisation. In general, boys had higher victimisation rates than girls. There were few risk factors related only to specific types of victimisation (e.g., child disability was uniquely associated with child maltreatment and peer/sibling victimisation). Instead, most risk factors were shared across nearly all victimisation types and also associated with polyvictimisation. These shared risk factors were: violent neighbourhood and low social cohesion, maternal adverse childhood experiences, younger maternal age, parental antisocial behaviour, intimate partner violence against mothers, and maternal depression. Interpretation These findings reveal a general pattern of accumulative risk effects for different types of victimisation and polyvictimisation, rather than unique risk profiles in children aged four year Prevention efforts should target risk factors at multiple levels (e.g.,: community, maternal and family and parent) during early childhood.

Abstract
Daily adherence to antiretroviral therapy (ART) increases the length and quality of life of people living with HIV (PLHIV). We explored whether socioeconomic status directly impacts ART adherence and whether part of the effect is mediated by pathways through alcohol misuse or food insecurity. A cross-sectional study was conducted in Rio de Janeiro/Brazil (November/2019 to March/2020) with PLHIV aged ≥ 18 years. Validated instruments were used to measure alcohol use, food insecurity, and ART adherence. Using structural equation modeling we assessed the direct and indirect effects of variables on ART adherence. Participants reported significant challenges: hunger: 12%, alcohol use: 64%, and missing ART doses: 24%. Results showed that lower socioeconomic status increased poor adherence and that this effect was mediated through higher food insecurity. Alcohol misuse also increased poor adherence through a strong direct effect. Providing socio-economic support coupled with interventions to mitigate alcohol's harmful impact can aid HIV care.

Abstract
OBJECTIVE Food Insecurity (FI) is the lack of daily access for everyone to quality food in sufficient quantity. In many populations, it presents as a chronic and persistent condition. This study analyzed the association between the length of time living with FI and sociodemographic conditions in households in a semi-arid municipality in the Brazilian Northeast between 2011 and 2019. DESIGN This is a population-based cohort study among families in the municipality in Northeast Brazil (2011, 2014, and 2019). FI was estimated through the Escala Brasileira de Insegurança Alimentar (EBIA, Brazilian Household Food Insecurity Measurement Scale), and the longitudinal category of time of living with FI was adopted to classify them according to the time they remained in FI during the cohort. The association with the sociodemographic profiles of the population was verified through multinomial logistic regression. SETTING Households in Semi-arid, Northeast of Brazil. PARTICIPANTS Household respondents interviewed in 2011, 2014 and 2019 (n=274). RESULTS Sixty-seven percent (67%) of families lived in FI in this period. Rural residence, low monthly per capita income, and low schooling of the household reference person increased the chances of these families living longer in FI. These overlapping conditions increased the odds of FI in the household. CONCLUSIONS Coping with FI requires intersectoral intervention that improves the sociodemographic conditions of the population.

Abstract
INTRODUCTION The Indigenous population of the Yanomami ethnic group in Brazil is currently facing a public health emergency due to the high number of deaths, mainly of children. Taking that into consideration, this study aims to analyze this crisis impact on the health of this population in the period between 2018 and 2022. METHODS The data presented were collected from the report called Yanomami Mission ("Missão Yanomami") published by the Brazilian Ministry of Health and, from it, a descriptive analysis of the Indigenous individuals' health was carried out for (i) the geographical distribution; ii) the number of deaths; (iii) the child death rate; (iv) the deaths of Indigenous individuals from preventable causes; (v) the causes of preventable diseases related to hygiene and basic sanitation, and the distribution of diarrheal diseases according to age groups; (vi) evaluation of the nutritional classification; vii) the percentage (%) of the complete vaccination scheme, and (viii) the coverage of prenatal appointments of Indigenous pregnant women. RESULTS The report included 31,017 individuals belonging to the Yanomami ethnic group, most of the participants were up to 39 years old (N = 26,377; 85.0%) and men (N = 15,836; 51.1%). During the period described in the report, the number of deaths reached 1285/31,017 (4.1%). When analyzing the deaths, the most representative age groups were those of children under 1 year old (505/1285; 39.9%), from 1 to 4 years old (178/1285; 13.8%), and the elderly from 60 to 79 years old (150/1285; 11.6%). The Indigenous individuals from this ethnic group presented a child death rate ~ 1.5 to 3.5 higher than that of the total Indigenous population in the country. Regarding the child death rate, the neonatal component represented 57.8% of the deaths and, in 2022, 93.0% of the pregnant women had less than six prenatal appointments. This population shows a high number of deaths due to preventable causes (N = 538) and cases of illnesses associated with hygiene and sanitation, for example (N = 35,103 cases/notifications). As for vaccination, the full vaccination scheme targeting children below 5 years old has not been met since 2018. CONCLUSION In the Indigenous population of the Yanomami ethnic group, a high number of deaths was observed, which affected mainly individuals under 1 year old. Among the factors associated with the deaths, mainly in children under 5 years old, most cases have preventable causes, which could be reduced by proper action promoting their health and preventing diseases.

Abstract
In 1895 and 2001, rust fungi affecting Licania trees (Chrysobalanchaceae) in Brazil were described as Uredo licaniae by Hennings in the state of Goiás and as Phakopsora tomentosae by Ferreira et al. in the state of Amazonas, respectively. Recently, a Licania rust fungus collected close to the Amazonian type location sharing symptoms with the former two species was subjected to morphological examinations and molecular phylogenetic analyses using 28S nuc rDNA (ITS2-28S) and cytochrome c oxidase subunit III (CO3) gene sequences. Since the original type specimen of Ph. tomentosae is considered lost, we carefully reviewed the type description and questioned the identity of the telium, which justified the description of the fungus as a Phakopsora species. Furthermore, the additional revision of the type material described by Hennings revealed that Ph. tomentosae is a synonym of U. licaniae. Based on the morphological examinations, disease symptoms, and shared hosts, we concluded that the newly collected material is conspecific with U. licaniae. However, the phylogenetic analyses rejected allocation in Phakopsora and instead assigned the Licania rust fungus in a sister relationship with Austropuccinia psidii (Sphaerophragmiaceae), the causal agent of the globally invasive myrtle rust pathogen. We therefore favored a recombination of U. licaniae (syn. Ph. tomentosae) into Austropuccinia and proposed the new name Austropuccina licaniae for the second species now identified for this genus. The fungus shares conspicuous symptoms with A. psidii, causing often severe infections of growing leaves and shoots that lead to leaf necrosis, leaf shedding, and eventually to the dieback of entire shoots. In view of the very similar symptoms of its aggressively invasive sister species, we briefly discuss the current state of knowledge about A. licaniae and the potential risks, and the opportunity of its identification.

Abstract
Many barriers to human immunodeficiency virus (HIV) testing among Black people exist. This study analysed the association between race/skin colour and lifetime HIV testing among adolescent men who have sex with men (AMSM) and transgender women (ATGW) in three Brazilian cities. This cross-sectional study was nested within the PrEP1519 cohort, a multicentre study of AMSM and ATGW aged 15-19 years in Belo Horizonte, Salvador, and São Paulo, Brazil. The outcome variable was the lifetime HIV testing (no or yes). The main exposure variable was self-reported race/skin colour as White and a unique Black group (composed of Pardo-mixed colour and Black, according to the Brazilian classification). Descriptive statistics and bivariate and multiple logistic regression analyses were conducted to estimate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) to determine the association between the main exposure and outcome, adjusted for covariates. White adolescents were tested more frequently than the unique Black group (64.0% vs. 53.7%, respectively; Ρ = 0.001). Multiple logistic regression analysis showed that the unique Black group of AMSM and ATGW had 26% (adjusted OR [aOR], 0.74; 95% CI, 0.55-0.98) and 38% (aOR, 0.62; 95% CI, 0.45-0.87) lower odds of being tested for HIV in a lifetime than Whites in model 1 and 2, respectively. Our findings highlight the role of racism in lifetime HIV testing among AMSM and ATGW. Therefore, an urgent need for advances exists in public policies to combat racism in Brazil.

Abstract
Friedreich's Ataxia (FRDA) is the leading cause of ataxia worldwide, but data on epidemiology and diagnostic journey are scarce, particularly in Latin America. Herein we estimated the prevalence of FRDA in the most populous Brazilian state and characterized the diagnostic odyssey of the disease. We received anonymized data of patients with FRDA from advocacy groups and physicians. Prevalence was estimated dividing the number of patients by the population of the state as reported in the last census. Patients were invited to answer an online survey to describe clinical data and diagnostic journey of the disease. FRDA estimated prevalence was 0.367:100,000, with a slight predominance of women (58.2% vs 41.7%). One hundred and four patients answered the survey (mean age of 37.3 ± 13.8 years; 75.9% classical and 24.0% late onset). On average, 6.2 ± 4.1 physicians were visited before reaching the diagnosis. Mean diagnostic delay was 7.8 ± 6.7 years; no difference between classical and LOFA groups was found. Most of the patients reported unsteadiness and gait abnormalities as the first symptom. Neurologists and orthopedical surgeons were the main specialties first sought by patients. We found a prevalence of 0.36:100,000 for FRDA in the state of São Paulo, Brazil. The disease is characterized by remarkable diagnostic delay, with no relevant differences between classical and LOFA patients.

Abstract
BACKGROUND Diabetes mellitus is a chronic disease that is growing worldwide. It is estimated that 15.7 million people aged between 20 and 79 years live with diabetes in Brazil, and the majority of cases are type 2 diabetes (T2D). To successfully manage diabetes, the patient needs to develop self-care activities. However, there is limited understanding of what self-care activities are performed by people with T2D in Brazil. OBJECTIVE This study aims to identify and map studies that evaluate self-care activities in T2D in Brazil. METHODS This is a scoping review protocol structured according to the methodological guidelines of the Joanna Briggs Institute. Six databases and gray literature were used. The process of searching, identifying, and evaluating the papers was carried out by 2 independent reviewers, guided by the assumptions established by the Joanna Briggs Institute. We sought to answer the following guiding question: How are self-care activities for people with T2D evaluated in Brazil? We included papers and publications in any language, from public and private domains, and with different methodological approaches. RESULTS Initial database searches produced a total of 681 results. These papers will be critically analyzed, and relevant information will be extracted. Quantitative and qualitative results of the papers reviewed will be presented to respond to the study's objective. We intend to publish the scoping review in the first half of 2024. CONCLUSIONS The protocol for this scoping review will evaluate the main self-care activities carried out by adults and older people with T2D in Brazil. The results may help identify knowledge gaps and contribute to future research and diabetes education interventions. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID) DERR1-10.2196/49105.

Abstract
In Santa Quitéria City, part of the population uses surface water for potation. These waters do not undergo any treatment before consumption. As the region has a deposit of uranium, assessing water quality becomes important. In the present study, the uranium activity concentration (AC) in becquerels per liter was determined in water samples from six points. Univariate statistics showed differences between the soluble and the particulate fraction (soluble AC > particulate AC). The particulate fraction showed no variation in AC among the six points. On the other hand, the soluble fraction and the total fraction presented different ACs between them. The multivariate statistics allowed to separate the soluble from the particulate fraction of the points. The same tools applied to the total fraction made it possible to differentiate the sampling points, grouping them ((#1, #2); (#3, #4), and (#5, #6)). The maximum mean value of AC found was 0.177 Bq∙L-1, corresponding to 25% of the chemical toxicity limit (0.72 Bq∙L-1). The maximum mean dose rate, 2.25 µSv∙year-1, is lower than the considered negligible dose rate (> 10 µSv∙year-1). The excess lifetime cancer risk was 10-6, two orders of magnitude smaller than the threshold considered for taking action. The assessment parameters used in this work indicate that the risk due to the uranium intake by the local population is negligible.

Abstract
BACKGROUND Neurofibromatosis type 1 (NF1) is a rare genetic disorder with a wide range of clinical manifestations, notably neurocutaneous features, that can lead to emotional and physical consequences. OBJECTIVES This study assessed the influence of sociodemographic factors and clinical features of the disease on the quality of life of Brazilian individuals with NF1. METHODS This is a descriptive cross-sectional study. Data were collected from 101 individuals with NF1 using the Brazilian version of the Impact of NF1 on Quality of Life Questionnaire (INF1-QoL), a form with information on sociodemographic characteristics, and an NF1 visibility self-evaluation scale. The relationship between variables was evaluated through statistical testing, and the significance level was defined as 0.05. RESULTS The study included 101 adults with NF1 aged 18 to 59 years, with a mean age of 35.54 years (±9.63) and a female predominance (n = 84, 83.17%). The mean total INF1-QoL score was 10.62 (±5.63), with a median of 10, minimum value of 0, and maximum of 31 points. Two characteristics of the participants were significantly associated with the quality of life: educational level (p = 0.003) and familial history of NF1 (p = 0.019). There was a statistically significant correlation between the INF1-QoL score and the degree of disease visibility (rho = 0.218; p = 0.028). STUDY LIMITATIONS Cross-sectional study, conducted with a convenience sample and using self-reported measures. CONCLUSIONS The findings support the significant impact of NF1 on quality of life. The authors recommend multidisciplinary follow-up for patients, with adherence to anticipatory clinical care measures, adequate pain control, psychological assistance, and genetic counseling.

Abstract
BACKGROUND Rhipicephalus (Boophilus) microplus is the most important tick species affecting cattle in the world. Under field conditions, the non-parasitic phase of R. (B.) microplus is unknown in the Amazon biome, including Brazil. The present study aimed to evaluate the non-parasitic phase of R. (B.) microplus in field (grass plots) and laboratory conditions. METHODS The study was conducted from September 2020 to April 2022 in an Amazonian region (Maranhão State, Brazil). We evaluated the biological parameters of R. (B.) microplus under laboratory and field conditions. Engorged females were exposed to experimental conditions every 14 days, totaling 20 months of study. The following biological parameters were observed: pre-oviposition period, egg mass incubation period, and maximum larval survival period. RESULTS Abiotic data (e.g., temperature and humidity) varied little throughout the year. Precipitation was the factor that varied the most throughout the year (dry ~ 30 mm3 and rain 400 mm3), and the parameters of pre-oviposition and pre-hatching are longer during the rainy season. A possible negative effect of the dry season on the percentage of hatched eggs was observed. Larval longevity in the plots of both control and free females was short (mean ~ 50-60 days), below that recorded for larvae under controlled conditions (mean ~ 95 days). CONCLUSIONS Rhipicephalus (Boophilus) microplus was able to complete its non-parasitic phase by producing host-seeking larvae in the pasture during all months of the study. The results indicate that R. (B.) microplus can complete up to six generations per year in biome Amazon. To our knowledge, this is the highest number of annual generations for R. (B.) microplus in Latin America.

Abstract
BACKGROUND Transgender women are disproportionately affected by both HIV and gender-based violence (GBV), defined as physical, sexual, or emotional violence perpetrated against an individual based on their gender identity/expression. While a growing body of evidence demonstrates that GBV leads to poor HIV care and treatment outcomes among cisgender women, less research has examined this association among transgender women. We assessed the impact of lifetime experiences of GBV on subsequent retention in HIV care and laboratory confirmed viral suppression among a sample of transgender women living with HIV (TWH) in Brazil. METHODS A pilot trial of a peer navigation intervention to improve HIV care and treatment among TWH was conducted in São Paulo, Brazil between 2018 and 2019. TWH were recruited and randomized into the intervention or control arm and participated in a baseline and 9-month follow-up survey and ongoing extraction of clinical visit, prescribing, and laboratory data. Generalized linear model regressions with a Poisson distribution estimated the relative risk (RR) for the association of lifetime physical and sexual violence reported at baseline with treatment outcomes (retention in HIV care and viral suppression) at follow-up, adjusting for baseline sociodemographic characteristics. RESULTS A total of 113 TWH participated in the study. At baseline, median age was 30 years, and the prevalence of lifetime physical and sexual violence was 62% and 45%, respectively. At follow-up, 58% (n = 66/113) were retained in care and 35% (n = 40/113) had evidence of viral suppression. In adjusted models, lifetime physical violence was non-significantly associated with a 10% reduction in retention in care (aRR: 0.90, 95% CI: 0.67, 1.22) and a 31% reduction in viral suppression (aRR: 0.69; 95% CI: 0.43, 1.11). Lifetime sexual violence was non-significantly associated with a 28% reduction in retention in HIV care (aRR: 0.72, 95% CI: 0.52, 1.00) and significantly associated with a 56% reduction in viral suppression (aRR: 0.44; 95% CI: 0.24, 0.79). CONCLUSION Our findings are among the first to demonstrate that lifetime experiences with physical and sexual violence are associated with poor HIV outcomes over time among transgender women. Interventions seeking to improve HIV treatment outcomes should assess and address experiences of GBV among this population. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03525340.

Abstract
Objective To estimate the prevalence of trachoma in indigenous and non-indigenous populations in selected areas of the state of Maranhão, in northeastern Brazil. Methods This was a population-based survey with probabilistic sampling. For the diagnosis of trachoma, external ocular examination was performed using head magnifying loupes, at 2.5X magnification. The prevalence of trachomatous inflammation - follicular (TF) in children aged 1-9 years and the prevalence of trachomatous trichiasis (TT) in the population aged ≥15 years were estimated. Relative frequencies of sociodemographic and environmental characteristics were obtained. Results The study included 7 971 individuals, 3 429 from non-indigenous populations and 4 542 from indigenous populations. The prevalence of TF in non-indigenous and indigenous populations was 0.1% and 2.9%, respectively, and the prevalence of TT among indigenous populations was 0.1%. Conclusions The prevalence of TF and TT in the two evaluation units in the state of Maranhão were within the limits recommended for the elimination of trachoma as a public health problem. However, the prevalence of TF was higher in the indigenous evaluation unit, indicating a greater vulnerability of this population to the disease. The prevalence of TF of below 5.0% implies a reduction in transmission, which may have resulted from improved socioeconomic conditions and/or the implementation of the World Health Organization SAFE strategy.

Abstract
Salt marshes are capable of mitigating metal pollution in coastal environments, yet the efficacy of this remediation is contingent upon various environmental factors and the plant species involved. This study investigates the influence of different anthropogenic activities, including industrial, urban, recreational (in an insular area), and dredging operations, on the bioaccumulation of eight metals (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) within Spartina alterniflora Loisel. in the Patos Lagoon estuary, Brazil. The research aims to assess the pattern of metal bioaccumulation and distribution within the plant's leaves, stems, and roots while also examining metal presence in the sediment. Our main findings reveal that S. alterniflora exhibited elevated metal levels in its plant structure directly related with the metal concentrations in the surrounding sediment, which, in turn, is related to the different anthropogenic activities. The industrial area presented the highest metal levels in sediment and plant sections, followed by dredging, insular, and urban areas. This same pattern was mirrored for the bioconcetration factors (BCF), with the BCFs consistently indicating active metal bioaccumulation across all areas and for most of the metals. This provides evidence of the metal bioaccumulation pattern in S. alterniflora, with elevated BCFs in areas affected by activities with a higher degree of impact. Translocation factors (TF) showed varying metal mobility patterns within the plant's below-ground and above-ground sections across the different areas, with only Hg exhibiting consistent translocation across all study areas. Zn was the primary metal contributor in all plant sections, followed by Pb and Cu. It is worth noting that Pb is a non-essential metal for this plant, highlighting the relationship between elevated Pb contributions in the plant sections and the bioaccumulation of this metal within the plant's structure. Overall, this study emphasizes the bioaccumulation capacity of S. alterniflora and elucidate the intrinsic connection between different anthropogenic activities and their impact on the resultant availability and bioaccumulation of metals by this salt marsh plant.

Abstract
The jugular foramen (JF) is located between the temporal and occipital bones. The JF is a primary pathway for venous outflow from the skull and passage of nerves. Variations are common in this region and may have clinical and surgical implications. To analyze the sexual dimorphism and JF morphology in skulls from Northeastern Brazil. 128 human skulls from the Anatomy Laboratory of the Federal University of Paraíba, 64 male and 64 female, were selected and the JFs analyzed for bone septation and the presence of a dome. Data analysis considered P<0.05 as significant. On at least one side, complete septation was observed in 26 skulls (20.3%), incomplete septation in 93 skulls (72.6%) and 61 skulls (47.6%) did not present septation. In 114 skulls (89%), 47.6% female and 41.4% male, have a unilateral presence of the dome and 71 (55.4%) have it bilaterally. Posterolateral compartment diameters and JF area had higher values on the right side in the total sample and separated by sex (P<0.05). Most morphometric variables of the anteromedial compartment were higher in male than in female (P<0.05), fact that was not observed in the posterolateral compartment (P>0.05). This study showed a higher prevalence of complete septation in males compared to females. Morphometric analysis presented a peculiar morphology of the JF in this study. These results suggests that the surgical approach to diseases that affect the JF may be peculiar to the studied population, confirming the importance of morphological analysis of the skull base.

Abstract
INTRODUCTION AND OBJECTIVES Autoimmune hepatitis (AIH) is a rare disease with a complex and not fully understood pathogenesis. Prognostic factors that might influence treatment response, relapse rates, and transplant-free survival are not well established. This study investigates clinical and biochemical markers associated with response to immunosuppression in patients with AIH. MATERIALS AND METHODS This retrospective cohort study included 101 patients with AIH treated with immunosuppressants and followed at the Federal University of Minas Gerais, Brazil, from 1990 to 2018. Pretreatment data such as clinical profiles, laboratory, and histological exams were analyzed regarding biochemical response at one year, histological remission, relapse, and death/transplantation rates. RESULTS Cirrhosis was present in 59 % of cases at diagnosis. One-year biochemical remission was observed in 55.7 % of the patients and was found to be a protective factor for liver transplant. Overall survival was 89 %. Patients with ascites at disease onset showed a higher aspartate aminotransferase (AST)/ alanine aminotransferase (ALT) ratio and elevated Model of end-stage liver disease (MELD) score. The presence of ascites was significantly associated with a 20-fold increase in mortality rate. CONCLUSIONS AIH has a severe clinical phenotype in Brazilians, with high rates of cirrhosis and low remission rates. Early diagnosis and treatment are essential for achieving remission and reducing complications. The presence of ascites is significantly associated with mortality, emphasizing the importance of monitoring and prompt intervention. This study also stresses the need for further research on AIH in Latin America.

Abstract
Rotavirus A (RVA) is a major cause of acute gastroenteritis globally that is classically genotyped by its two immunodominant outer capsid proteins, VP7 (G-) and VP4 (P-). Recent evidence suggests that the reassortant equine-like G3P[8] strain played a substantial role in RVA transmission in Brazil since 2015. To understand its global emergence and dissemination in Brazilian territory, stool samples collected from 11 Brazilian states (n = 919) were genotyped by RT-qPCR and proceeded to sequence the VP7 gene (n = 102, 79 being newly generated) of the G3P[8] samples with pronounced viral loads. Our phylogenetic genotyping showed that G3P[8] became the dominant strain in Brazil between 2017 and 2020, with equine-like variants representing 75%-100% of VP7 samples in this period. A Bayesian discrete phylogeographic analysis strongly suggests that the equine-like G3P[8] strain originated in Asia during the early 2010s and subsequently spread to Europe, the Caribbean, and South America. Multiple introductions were detected in Brazil between 2014 and 2017, resulting in five national clusters. The reconstruction of the effective population size of the largest Brazilian cluster showed an expansion until 2017, followed by a plateau phase until 2019 and subsequent contraction. Our study also supports that most mutations fixed during equine-like G3P[8] evolution were synonymous, suggesting that adaptive evolution was not an important driving force during viral dissemination in humans, potentially increasing its susceptibility to acquired immunity. This research emphasizes the need for comprehensive rotavirus genomic surveillance that allows close monitoring of its ever-shifting composition and informs more effective public health policies.IMPORTANCEOur original article demonstrated the origin and spread in a short time of equine-like G3P[8] in Brazil and the world. Due to its segmented genome, it allows numerous mechanisms including genetic drift and reassortment contribute substantially to the genetic diversity of rotavirus. Although the effectiveness and increasing implementation of vaccination have not been questioned, a matter of concern is its impact on the emergence of escape mutants or even the spread of unusual strains of zoonotic transmission that could drive epidemic patterns worldwide. This research emphasizes the need for comprehensive rotavirus genomic surveillance, which could facilitate the formulation of public policies aimed at preventing and mitigating its transmission.

Abstract
From the theoretical perspective of the cartography of the micropolitics of living labor in action, the objective was to analyze the work process of the "street clinic" team based in a primary care unit in the city of Rio de Janeiro, Brazil, in the management of tuberculosis cases in the context of the Covid-19 pandemic. This is an exploratory qualitative research. Between May and December 2021, seven professionals from the street clinic team were interviewed, and participant observation was conducted with field diary records. Three thematic axes emerged from the interviews related to people experiencing homelessness in the context of the Covid -19 pandemic: 1) Challenges, potentialities, and weaknesses of tuberculosis care; 2) Building intersectoral care networks for monitoring individuals with tuberculosis; and 3) The street as a space for care production: the work process of the street clinic in tuberculosis management. It is concluded that caring for people experiencing homelessness with tuberculosis in the context of the Covid -19 pandemic requires not only managing clinical protocols but also building shared work with the intra and intersectoral network. In addition to the task of being in the territory, the outpatient service in the territory must also be a street outpatient service, especially regarding tuberculosis treatment.

OBJECTIVE This work compares the marketing authorization, labels and dosage forms of medicines in the WHO Model List of Essential Medicines for Children (EMLc) in China, the Russian Federation and Brazil to urge policymakers to pay more attention to paediatric medication. METHODS Medicines were selected from the 8th EMLc. By searching relevant databases, which include different types of medical information in China, the Russian Federation and Brazil, the marketing authorization, labels and dosage forms of paediatric medicines in the three countries were evaluated. RESULTS A total of 485 drug products containing 312 active pharmaceutical ingredients listed in the WHO EMLc were evaluated. Among them, 344 products were approved for use in China, 286 in the Russian Federation and 264 in Brazil. Out of the 344 approved medicines, 317 (92.15%) were authorized for paediatric use in China, 224 (78.32%) in the Russian Federation and 218 (82.58%) in Brazil. In terms of guidance information labelling on drug labels, 75.08%, 83.04% and 88.07% of paediatric drugs approved in China, the Russian Federation and Brazil, respectively, clearly indicated the usage and dosage for paediatric use. Additionally, injections and tablets were the most prevalent dosage forms in these three countries. CONCLUSION There is still scope for enhancing the marketing authorization and development of dosage forms for paediatric medicines in the three countries. Furthermore, additional measures are being implemented to enhance the information provided on drug labels for children, particularly in China.

Abstract
The SARS-CoV-2 XBB is a group of highly immune-evasive lineages of the Omicron variant of concern that emerged by recombining BA.2-descendent lineages and spread worldwide during 2023. In this study, we combine SARS-CoV-2 genomic data (n = 11,065 sequences) with epidemiological data of severe acute respiratory infection (SARI) cases collected in Brazil between October 2022 and July 2023 to reconstruct the space-time dynamics and epidemiologic impact of XBB dissemination in the country. Our analyses revealed that the introduction and local emergence of lineages carrying convergent mutations within the Spike protein, especially F486P, F456L, and L455F, propelled the spread of XBB* lineages in Brazil. The average relative instantaneous reproduction numbers of XBB* + F486P, XBB* + F486P + F456L, and XBB* + F486P + F456L + L455F lineages in Brazil were estimated to be 1.24, 1.33, and 1.48 higher than that of other co-circulating lineages (mainly BQ.1*/BE*), respectively. Despite such a growth advantage, the dissemination of these XBB* lineages had a reduced impact on Brazil's epidemiological scenario concerning previous Omicron subvariants. The peak number of SARI cases from SARS-CoV-2 during the XBB wave was approximately 90%, 80%, and 70% lower than that observed during the previous BA.1*, BA.5*, and BQ.1* waves, respectively. These findings revealed the emergence of multiple XBB lineages with progressively increasing growth advantage, yet with relatively limited epidemiological impact in Brazil throughout 2023. The XBB* + F486P + F456L + L455F lineages stand out for their heightened transmissibility, warranting close monitoring in the months ahead. IMPORTANCE Brazil was one the most affected countries by the SARS-CoV-2 pandemic, with more than 700,000 deaths by mid-2023. This study reconstructs the dissemination of the virus in the country in the first half of 2023, a period characterized by the dissemination of descendants of XBB.1, a recombinant of Omicron BA.2 lineages evolved in late 2022. The analysis supports that XBB dissemination was marked by the continuous emergence of indigenous lineages bearing similar mutations in key sites of their Spike protein, a process followed by continuous increments in transmissibility, and without repercussions in the incidence of severe cases. Thus, the results suggest that the epidemiological impact of the spread of a SARS-CoV-2 variant is influenced by an intricate interplay of factors that extend beyond the virus's transmissibility alone. The study also underlines the need for SARS-CoV-2 genomic surveillance that allows the monitoring of its ever-shifting composition.

Abstract
Bats have a long evolutionary history with trypanosomatids, but the role of these flying mammals on parasite transmission cycles in urban areas, especially for Trypanosoma and Leishmania species, remains poorly known. The objective of this study was to evaluate the species richness of trypanosomatids parasitizing a bat community in Campo Grande (CG), a state capital within the Cerrado of the Brazilian Midwest. We evaluated 237 bats of 13 species by means of hemoculture and molecular detection in spleen samples. The bat community of CG appears to participate in the transmission cycles of various species of trypanosomatids. We report an overall trypanosomatid detection rate of 34.2% (n = 81), involving 11 out of 13 sampled bat species. We identified six species of trypanosomatids from 61 bats by analyzing SSU rRNA and/or kDNA: Trypanosoma cruzi DTU TcI, T. c. marinkellei, T. dionisii, Leishmania infantum, L. amazonensis, and T. janseni, with this latter being detected by hemoculture for the first time in a bat species. We also detected a Molecular Operational Taxonomic Unit, Trypanosoma sp. DID, in the phyllostomids Glossophaga soricina and Platyrrhinus lineatus. The highest trypanosomatid richness was observed for Sturnira lilium, which hosted three species: L. infantum, T. dionisii and T. janseni. Given that visceral leishmaniasis is endemic in CG, special focus should be placed on L. infantum. Moreover, L. amazonensis and T. cruzi warrant attention, since these are zoonotic parasites responsible for human cases of tegumentary leishmaniasis and Chagas disease, respectively. In this respect, we discuss how bat communities may influence the Leishmania spp. transmission in endemic areas.

Abstract
Disseminated leishmaniasis (DL) is an emergent severe disease manifesting with multiple lesions. To determine the relationship between immune response and clinical and therapeutic outcomes, we studied 101 DL and 101 cutaneous leishmaniasis (CL) cases and determined cytokines and chemokines in supernatants of mononuclear cells stimulated with leishmania antigen. Patients were treated with meglumine antimoniate (20 mg/kg) for 20 days (CL) or 30 days (DL); 19 DL patients were instead treated with amphotericin B, miltefosine, or miltefosine and meglumine antimoniate. High levels of chemokine ligand 9 were associated with more severe DL. The cure rate for meglumine antimoniate was low for both DL (44%) and CL (60%), but healing time was longer in DL (p = 0.003). The lowest cure rate (22%) was found in DL patients with >100 lesions. However, meglumine antimoniate/miltefosine treatment cured all DL patients who received it; therefore, that combination should be considered as first choice therapy.

Abstract
Colonialism's enduring impact on Brazil has had significant implications for health and oncology outcomes. This historical essay delves into the profound changes brought about by the transatlantic slave trade from Africa to the Americas, particularly in terms of its influence on the economy, sociocultural habits, and health outcomes. This essay explores the enduring connections between the colonial period's operational dynamics in Brazil and the current epidemiological panorama of head and neck cancer (HNC). The examination provides original insights on the role of tobacco and alcohol production and consumption, alongside the investigation of structural racism, which contributes to disparities in access to diagnosis, treatment, and prognosis for patients with HNC. This article presents novel visions and an analysis of evidence-based strategies to disrupt the adverse impact of colonialism's legacy on the epidemiology of HNC in Brazil.

Abstract
OBJECTIVE To assess menstrual hygiene management (MHM) and period poverty in a group of low- and medium-income menstruating people. METHODS A cross-sectional study was conducted at the University of Campinas, Brazil, from January to June 2022 with 535 participants aged 18-49. For data collection, we used the abbreviated version of the WHO Quality-of-Life questionnaire (WHOQOL-BREF) and a pre-tested questionnaire with items regarding MHM and period poverty. RESULTS We found an inverse relationship between the risk of no access to supplies to perform menstrual hygiene, which increased by 2.5% and each point less in the environmental domain of quality of life (QoL), and this risk increased by up to 3.1 times among participants who reported difficulty making ends meet. The risk of not having adequate conditions to perform menstrual hygiene at home increased by up to 2.6% for every one-point drop in the environmental domain of QoL. The risk of not having adequate conditions to perform menstrual hygiene outside the home increased by up to 1.3% for less points in the psychological domain of QoL, and 44.4% of those who indicated inadequate conditions for menstrual hygiene reported two or more childbirths. CONCLUSIONS Menstruating people who have an increased risk of lacking menstrual supplies and have an increased risk of inadequate conditions for MHM at home and outside the home, as well as those who have two or more deliveries and those having difficulties making ends meet, scored low on the QoL, especially in the environmental and psychological dimensions.

Abstract
OBJECTIVES Eating competence is an intraindividual approach to eating, behaviors, and attitudes related to eating, with repercussions on the individual and family. In pediatric celiac disease, the family is involved in the gluten-free diet management, the only treatment available. A gluten-free diet might affect eating competence because gluten-free diet compliance requires knowledge about food, meal planning, and attention to food choices. The objective is to access eating competence in caregivers of children with celiac disease and the association between caregivers' eating competence, children's adherence to a gluten-free diet, and sociodemographic data of participants. METHODS This cross-sectional study used a snowball spread method by applying a questionnaire, including sociodemographic data, data related to health, eating habits, and the Satter Eating Competence Inventory version validated for the Brazilian population. The sample consisted of 220 Brazilian parents or caregivers of celiac disease children. The scores of the Satter Eating Competence Inventory version validated for the Brazilian population were described in terms of means, SDs, medians, and interquartile range. Student's t test and analysis of variance followed by Tukey's post hoc tests were applied, and the association with the variables of interest was analyzed using Pearson χ2 tests. The tests were conducted considering bilateral hypotheses and a 5% significance level. RESULTS Participants' sex, schooling level, and income did not affect their eating competence. Competent eaters were mostly those with normal weight, following a gluten-free diet, with children complying with a gluten-free diet, and who have meals with family and prepare them at home. Different from vegetable consumption, participants' eating competence did not differ considering the frequency of children's fruit consumption. CONCLUSIONS The caregivers of children with celiac disease have greater eating competence scores than general Brazilian adults, and caregivers of children with celiac disease who comply with the gluten-free diet have higher eating competence scores.

Abstract
OBJECTIVE This study aimed to compare the prevalence and socio-economic determinants of frailty in older adults in Brazil and Chile using nationally representative survey data. STUDY DESIGN Analytical research using data from the Brazilian Longitudinal Study of Aging (ELSI) and the Chilean National Health Survey (ENS) conducted in Brazil and Chile between 2015 and 2017. METHODS The study included 5484 older adults aged 60 years or older in Brazil and 2031 in Chile. Frailty was measured using the FRAIL index, and logistic regression models were used to identify the determinants of frailty. RESULTS The prevalence of frailty is 15.6% and 12.6% in Brazil and Chile, respectively. Frailty is associated with several factors, including age, sex, living alone, residing in urban areas, and decreased life satisfaction. However, the analysis revealed notable differences between countries. A greater number of significant variables were associated with frailty in Brazil, whereas Chile displayed fewer categories with significant odds. Health insurance had no significant effect in either of the two countries. CONCLUSIONS The limitations in data sources and methodologies make it challenging to compare frailty determinants in Latin America. This study overcomes these barriers and shows that, even within the same region, significant differences exist. Levels and characteristics that are important in one country may not be so in another. The results emphasize the need to consider contextual factors in the implementation of emerging social and healthcare policies, such as home-based long-term care.

Abstract
Introduction The coronavirus disease (COVID)-19 has had a great impact on several aspects related to the population's health, including the vaccination adherence rate. This study describes how childhood vaccination coverage (CVC) in Brazil was affected by the pandemic in the period from 2020 to 2022 and explores the relationship between this data and the Human Development Index (HDI), and the number of votes received in the government with a right-wing political ideology. Methods An ecological analysis of CVC was carried out including 12 vaccines. The HDI was evaluated considering the HDI-General, HDI-Income, HDI-Longevity, and HDI-Education. The percentage of valid votes received by the former president (right-wing political ideology) was also obtained. Spearman correlation tests were applied to compare markers. Results During the period analyzed, it was observed a linear growth trend in CVC between 2015 and 2018 regarding all vaccines. However, from 2018 onwards, after the presidential elections in Brazil, the CVC reduced significantly, showing an even more pronounced decrease with the start of the COVID-19 pandemic. This reduction in CVC observed for some vaccines was related to the higher percentage of votes for the government with a right-wing political ideology, especially in relation to the BCG (bacillus Calmette and Guerin) and pentavalent (protecting against diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type b bacteria) vaccines. In addition, when analyzing the HDI, it was observed that the lowest values of this indicator were associated with a more expressive reduction in CVC, mainly related to yellow fever, pentavalent, 10-valent pneumococcal conjugate, Human rotavirus, and triple viral (protecting against measles, mumps, and rubella - MMR) vaccines. Conclusion Although Brazil has a successful and exemplary record in combating several diseases, mainly due to the high rate of CVC, the continuous reduction in this coverage must be thoroughly evaluated by health managers.

Abstract
Understanding estuarine diversity patterns is crucial to highlight the ecological value of coastal ecosystems for fish assemblages. To increase our knowledge, we investigated the functional diversity of fish assemblages in five estuarine habitats (sandy beaches, mudflats, seagrass meadows, mangrove fringes, and estuarine riparian vegetation) in a tropical estuary of Brazil. Functional diversity metrics were assessed considering seven fish functional traits and calculated using functional indices, PCoA (functional spaces), and community-weighted mean (CWM). Then, a unified RLQ and fourth-corner analysis were used to evaluate environment-trait relationships. A total of 27,036 individuals of 119 species were recorded in all habitats. Functional diversity showed similar trends to estuarine habitats, which were more driven by the spatial configuration rather than by their structure, emphasizing the importance of environmental heterogeneity. There was a greater occupation of functional space to habitats located in the lower estuary compared to the upper estuary. Furthermore, body shapes and trophic guilds were the most common traits related to changes in functional diversity between habitats. The RLQ analysis revealed differences in trait composition between habitats influenced by salinity and transparency, although the fourth corner method did not show a significant relationship between fish functional traits and environmental variables. Our results suggest that the mosaic of habitats support the high functional diversity of fishes in tropical estuaries.

Abstract
Ticks are obligate hematophagous parasites that can transmit to vertebrate hosts several pathogens, including viruses, bacteria, protozoa and helminths. Among these agents, some Borrelia species some Borrelia species cause disease in humans and other vertebrate hosts; therefore, they have medical and veterinary health importance. To gather additional information on Borrelia species in Brazil, the current study aimed to detect the presence of these species in Ornithodoros cavernicolous ticks collected in September 2019 from cement pipes that are used by bats as shelter in a farm located in the midwestern region of Brazil. DNA samples obtained from 18 specimens of O. cavernicolous were subjected of two polymerase chain reactions, targeting a segment of the Borrelia fla B gene. Of the samples tested, only one (6 %, 1/18) showed amplification. The nucleotide sequence of the amplified DNA showed more than 97 % (293/300) identity with a sequence of a Borrelia sp. detected in blood collected from a bat from Macaregua Cave, Colombia, and more than 97 % (292/300) detected in lungs from vampire bats from northeastern Brazil. The deduced amino acid sequences were identical to each other. Phylogenetic analysis indicated that these sequences formed a group of Borrelia species (putatively associated with bats) that is closely related to sequences of Borrelia species of the Lyme borreliosis group. Further investigations should be carried out in order to determine whether the sequence of the Borrelia sp. we found belongs to a new taxon. It will also be of great importance to determine which vertebrate hosts, besides bats, O. cavernicolous ticks can parasitize in order to investigate whether the Borrelia sp. we found may be transmitted and cause disease to the other vertebrate hosts.

Abstract
BACKGROUND In 2012, the Brazilian government launched a radiotherapy (RT) expansion plan (PER-SUS) to install 100 linear accelerators. This study assesses the development of this program after eight years. METHODS Official reports from the Ministry of Health (MoH) were reviewed. RT centres projects status, timeframes, and cost data (all converted to US dollars) were extracted. The time analysis was divided into seven phases, and for cost evaluation, there were five stages. The initial predicted project time (IPPT) and costs (estimated by the MoH) for each phase were compared between the 18 operational RT centres (able to treat patients) and 30 non-operational RT centres using t-tests, ANOVA, and the Mann-Whitney U. A p-value < 0.05 indicates statistical significance. RESULTS A significant delay was observed when comparing the IPPT with the overall time to conclude each 48 RT centres project (p < 0.001), with considerable delays in the first five phases (p < 0.001 for all). Moreover, the median time to conclude the first 18 operational RT centres (77.4 months) was shorter compared with the 30 non-operational RT centres (94.0 months), p < 0.001. The total cost of 48 RT services was USD 82,84 millions (mi) with a significant difference in the per project median total cost between 18 operational RT centres, USD1,34 mi and 30 non-operational RT centres USD2,11 mi, p < 0.001. All phases had a higher cost when comparing 30 non-operational RT centres to 18 operational RT centres, p < 0.001. The median total cost for expanding existing RT centres was USD1,30 mi versus USD2,18 mi for new RT services, p < 0.0001. CONCLUSION After eight years, the PER-SUS programs showed a substantial delay in most projects and their phases, with increased costs over time. POLICY SUMMARY Our findings indicate a need to act to increase the success of this plan. This study may provide a benchmark for other developing countries trying to expand RT capacity.

Abstract
Background Self-harm is considered an important public health issue and is comprised by a wide range of definitions and behaviours. It is estimated that suicide affects more than 700,000 individuals every year, although, globally, there is a lack of evidence on other self-harm behaviour, such as attempted suicide. The objective of this study is to report and examine temporal trends of notifications, hospitalisations related to self-harm and suicide rates in Brazil between 2011 and 2022, as well as investigating differences in sociodemographic characteristics, methods, and region. Methods This ecological study used secondary, Brazilian Health Information System data between 2011 and 2022. Self-harm notifications were collected from the Notifiable Diseases Information System (SINAN); self-harm hospitalisations from the Hospital Information System (SIH), and suicide data from the Mortality Information System (SIM). We calculated self-harm notifications, hospitalisations, and suicide rates by sex, age, race, region, and overall. We assessed time-related trends using Joinpoint regression analyses. Findings From 2011 to 2022, 720,480 self-harm notifications, 104,458 self-harm hospitalisations, and 147,698 suicides were recorded in Brazil. In this period, self-harm notifications (AAPC: 21.13 (CI: 17.50, 25.33)) and suicide (AAPC: 3.70 (CI: 3.05, 4.38)) have increased in the country. Male adults (25-59 years old) and the elderly (>60 years old) continue to be the groups most affected by suicide, with respective rates of 9.59 and 8.60/100,000 in 2022. However, the largest percentage increases have been seen in young people (AAPC: 6.14 (CI: 4.57, 7.88)). The Indigenous population had the highest self-harm notification (103.72, 10,000) and suicide (16.58/100,000) rates, but the lowest hospitalisation rates (1.14/100,000) in 2022), compared to the overall population (70.06, 7.27, and 4.69/100,000, respectively, in 2022). Interpretation The observed trend of increased self-harm notifications and suicide rates suggests the need for a greater allocation of resources to strategies to prevent self-harm and suicide. The Indigenous population seems to be the group with less access to healthcare.
