UNASSIGNED: To describe temporal and spatial patterns and identify the factors associated with the incidence of HIV/AIDS among young people in Brazil.
UNASSIGNED: Ecological study of young Brazilians aged 15-24 years with reported HIV/AIDS, from 2001 to 2021. The Joinpoint method was used for the temporal analysis. Spatial clusters were detected using Bayesian methods, spatial autocorrelation, Getis-Ord Gi*, and scan techniques. Four non-spatial and spatial regression models were used to identify factors associated with the result. All statistical analyses considered p < 0.05.
UNASSIGNED: In Brazil, the average incidence was 12.29 per 100 000 inhabitants, with an annual increase of 7.3% in the period 2007-2014 and a subsequent 3.4% decrease in 2014-2021. A high-high pattern and hotspots were observed, mainly in municipalities in the South, Southeast, Central-West, and North regions. The primary cluster was located in 572 municipalities in Rio Grande do Sul and Santa Catarina, with the highest relative risks in Manaus (Amazonas) and Rondonópolis (Mato Grosso). The illiteracy rate (β = -0.08), GINI Index (β = -3.74) and Family Health Strategy coverage (β = -0.70) were negatively associated with the result. In contrast, the Firjan Municipal Development Index (β = 2.37), Social Vulnerability Index (β = 6.30), percentage of Bolsa Família recipients (β = 0.04), and per capita income (β = 0.008) showed a positive association.
UNASSIGNED: There was an upward trend in the incidence of HIV/AIDS until 2014, followed by a decline until 2021. High-rate clusters were concentrated in municipalities in the North, South, Southeast and Central-West regions in particular. Indicators of socioeconomic vulnerability had positive or negative effects on the result, depending on the territory investigated.
UNASSIGNED: Describir el patrón temporal y espacial, y determinar los factores asociados a la incidencia de infección por el VIH/sida en jóvenes en Brasil.
UNASSIGNED: Estudio ecológico en jóvenes brasileños de 15 a 24 años con diagnóstico de infección por el VIH/sida en el período 2001-2021. Para el análisis temporal se utilizó el método de regresión de puntos de inflexión (joinpoint). Los conglomerados espaciales se detectaron con métodos Bayesianos y de autocorrelación espacial, Gi* de Getis-Ord y escaneo. Se utilizaron cuatro modelos de regresión espacial y no espacial para detectar los factores asociados al resultado. En todos los análisis estadísticos se estableció un valor de p < 0,05 como umbral de significación.
UNASSIGNED: En Brasil, la incidencia media fue de 12,29 por 100 000 habitantes, con un aumento del 7,3% anual en el período 2007-2014 y una reducción posterior del 3,4% en el período 2014-2021. Se observó un patrón alto/alto y la presencia de puntos calientes, principalmente en municipios del Sur, Sudeste, Centro-Oeste y Norte. El principal conglomerado se localizó en 572 municipios de Rio Grande do Sul y Santa Catarina, y los riesgos relativos más altos se observaron en Manaus (Amazonas) y Rondonópolis (Mato Grosso). La tasa de analfabetismo (β = -0,08), el índice de Gini (β = -3,74) y la cobertura de la estrategia de salud familiar (β = -0,70) mostraron una asociación negativa con el resultado. En cambio, el índice de Firjan de desarrollo municipal (β = 2,37), el índice de vulnerabilidad social (β = 6,30), el porcentaje de personas que reciben ayuda del programa de bienestar social Bolsa Família (β = 0,04) y los ingresos per cápita (β = 0,008) mostraron una asociación positiva.
UNASSIGNED: Hubo una tendencia al aumento de la incidencia de infección por el VIH/sida hasta el 2014, con una reducción posterior hasta el 2021. Los conglomerados de tasas elevadas se concentraron especialmente en los municipios de las regiones Norte, Sur, Sudeste y Centro-Oeste. Los indicadores de vulnerabilidad socioeconómica tienen una influencia positiva o negativa en el resultado, según el territorio investigado.

OBJECTIVE: Women\'s mortality at a reproductive age has been a global concern, and its decrease has been incorporated as a target of the UN Sustainable Development Goals. The aim of this study was to describe the spatial-temporal evolution of mortality rates among women of reproductive age in Brazilian municipalities by groups of causes and socioeconomic indicators from 2000 to 2018.
METHODS: Ecological analysis.
METHODS: This work was an ecological, descriptive study that analyzed estimates of mortality rates among women of reproductive age (15-49 years) by main groups of causes of death from the Global Burden of Disease (GBD) study in three consecutive trienniums, T1 (2000-2002), T2 (2009-2011), and T3 (2016-2018). To quantify the temporal evolution in mortality rates, the present study calculated the percentage change for each triennium. The spatial analysis of mortality rates was carried out using Moran\'s index. The Pearson coefficient was used to analyze the correlation between the data.
RESULTS: A significant decline in mortality rates was found for all groups of causes in all regions of the country. Despite the downward trend, the percentage change from 2009 to 2011 to 2016 to 2018 showed a decrease in the group of Noncommunicable Diseases (NCDs) and external causes. The decline in mortality rates of women due to external causes showed only a minimal change in the North and Northeast regions from T2 to T3, whereas a cluster of neighboring municipalities with high mortality rates persisted in the municipalities of the South region and in the state of Roraima. The ranking of the main causes of death in Brazilian municipalities showed an increase in neoplasms in detriment to cardiovascular diseases (CVDs).
CONCLUSIONS: The main causes of death in women of reproductive age at a more local level could be used to recognize inequalities and to develop interventions aimed at tackling premature and preventable deaths.

BACKGROUND: To analyse the temporal trends and spatiotemporal distribution of leprosy relapse in Brazil from 2001 to 2021.
METHODS: An ecological study with a temporal trend approach and space-time analysis of leprosy relapse in Brazil was carried out with data from the Notifiable Diseases Information System.
RESULTS: A total of 31 334 patients who experienced leprosy relapse were identified. The number of recurrent cases tended to increase throughout the study period, and this increase was significant among females and in almost all age groups, except for those <15, 50-59 and ≥70 y. Several clusters of high- and low-risk patients were identified across all regions with a heterogeneous distribution.
CONCLUSIONS: The burden of relapse showed an increasing trend in some groups and was distributed in all regions.

The study of consciousness has developed well-controlled, rigorous methods for manipulating and measuring consciousness. Yet, in the process, experimental paradigms grew farther away from everyday conscious and unconscious processes, which raises the concern of ecological validity. In this review, we suggest that the field can benefit from adopting a more ecological approach, akin to other fields of cognitive science. There, this approach challenged some existing hypotheses, yielded stronger effects, and enabled new research questions. We argue that such a move is critical for studying consciousness, where experimental paradigms tend to be artificial and small effect sizes are relatively prevalent. We identify three paths for doing so-changing the stimuli and experimental settings, changing the measures, and changing the research questions themselves-and review works that have already started implementing such approaches. While acknowledging the inherent challenges, we call for increasing ecological validity in consciousness studies.

Ecometabolomics could be implemented as a powerful tool in molecular ecology studies, but it is necessary to know the baseline of certain metabolites and understand how different traits could affect the metabolome of the animals. Therefore, the main objective of this study was to provide values for the nutritional metabolome profile of different diet groups and animal species, as well as to study the differences in the metabolomic profile due to the effect of diet type and species. To achieve this goal, blood samples were taken from healthy animals (n = 43) of different species: lion (Panthera leo), jaguar (Panthera onca), chimpanzee (Pan troglodytes), bison (Bison bison), gazelle (Gazella cuvieri) and fallow deer (Dama dama), and with different types of diet (carnivore, herbivore and omnivore). Each blood sample was analysed to determine nutritional metabolites. The main results this study provides are the nutritional metabolic profile of these animals based on the type of diet and the animal species. A significant effect of the dietary type was found on nutritional metabolite levels, with those metabolites related to protein metabolism (total protein and creatine) being higher in carnivores. There is also an effect of the species on nutritional metabolites, observing a metabolome differentiation between lion and jaguar. In the case of herbivores, bison showed higher levels of uric acid and cholesterol, and lower urea levels than gazelle and fallow deer. More molecular ecology studies are needed to further the knowledge of the metabolism of these animals.

BACKGROUND: Tuberculosis is one of the most significant infectious diseases for global public health. The reallocation of healthcare resources and the restrictions imposed by the COVID-19 pandemic have hindered access to TB diagnosis and treatment. Increases in unfavorable outcomes of the disease have been observed in Brazil. The objective of this study was to analyze the spatial distribution of unfavorable TB treatment outcomes in Brazil before and during the pandemic.
METHODS: An ecological study with spatial analysis was conducted with all 5569 municipalities in Brazil. All reported cases of tuberculosis between January 2010 and December 2021, as well as reported cases of COVID-19 from February 2020 to December 2021, were included. The outcomes studied encompass loss to follow-up, drug-resistant tuberculosis, and death. The Getis Ord GI* technique was employed to assess spatial association, and the Kernel density estimator was used to identify areas with concentrated increases or decreases in outcomes. Bivariate Local Moran\'s I was used to examine the spatial association between outcomes and COVID-19 incidence. The study was approved by the Research Ethics Committee of Ribeirão Preto Nursing School, University of São Paulo.
RESULTS: There were 134,394 cases of loss to follow-up, 10,270 cases of drug resistance, and 37,863 deaths. Clusters of high and low values were identified for all three outcomes, indicating significant changes in the spatial distribution patterns. Increases in concentrations were observed for lost to follow-up cases in the Southeast, while reductions occurred in the Northeast, South, and Midwest. Drug-resistant tuberculosis experienced an increase in the Southern and Southeastern regions and a decrease in the Northeast and South. TB-related deaths showed notable concentrations in the Midwest, Northeast, South, and Southeast. There was an increase in high occurrence clusters for deaths after 2020 and 2021 in the Northeast.
CONCLUSIONS: The pandemic has brought additional challenges, emphasizing the importance of enhancing efforts and disease control strategies, prioritizing early identification, treatment adherence, and follow-up. This commitment is vital for achieving the goal of tuberculosis elimination.

UNASSIGNED: To perform a systematic review of scientific publications addressing the use of stratification methods to define risk areas for measles transmission.
UNASSIGNED: Articles published in English, Portuguese, and Spanish in journals indexed in the SciELO, PubMed, and LILACS databases were selected. The search terms risk assessment AND measles were used without date limits. Editorials, opinion articles, individual-level observational studies, and publications that did not focus on the application of methods to stratify measles transmission risk areas were excluded. Year of publication, authorship, country where the study was performed, objective, geographic level of analysis, method used, indicators, and limitations were recorded in a data form.
UNASSIGNED: Thirteen articles published between 2011 and 2022 in nine countries from the six World Health Organization (WHO) regions were selected. Of these, 10 referred to the Measles Risk Assessment Tool developed by the WHO/Centers for Disease Control and Prevention. Only one study adapted the tool to the local context. The risk stratification indicators used in the selected studies focused on a combination of the following dimensions: population immunity, quality of surveillance systems, and epidemiologic status. The systematic output of data with adequate quality and coverage was a noteworthy aspect hindering risk stratification.
UNASSIGNED: There seems to be limited dissemination of measles risk stratification strategies, especially at local levels. The need to train human resources to process and interpret risk analyses as part of the routine of surveillance services is emphasized.
UNASSIGNED: Realizar una revisión sistemática de las publicaciones científicas en las que se han abordado experiencias de aplicación de métodos de estratificación para definir las zonas de riesgo de transmisión del sarampión.
UNASSIGNED: Se seleccionaron artículos publicados en español, inglés o portugués en revistas indizadas en las bases de datos SciELO, PubMed y LILACS. En la búsqueda se utilizaron los descriptores \"risk assessment\" y \"measles\", sin limitaciones en la fecha de publicación. Se excluyeron editoriales, artículos de opinión, estudios de observación de pacientes individuales y publicaciones que no tratasen de la aplicación de métodos de estratificación de zonas de riesgo de transmisión del sarampión. Se empleó un formulario para extraer la información sobre año de publicación, autoría, país de realización del estudio, objetivo, escala geográfica, método utilizado, indicadores y limitaciones.
UNASSIGNED: Se seleccionaron 13 artículos publicados entre el 2011 y el 2022 en nueve países de las seis regiones de la Organización Mundial de la Salud (OMS). En 10 de ellos se utilizó como referencia la herramienta de evaluación del riesgo de sarampión creada por la OMS y los Centros para el Control y la Prevención de Enfermedades de Estados Unidos. Solamente en un estudio se adaptó la herramienta al contexto local. Los indicadores utilizados para la estratificación del riesgo se basaron en una combinación de las dimensiones de inmunidad poblacional, calidad de los sistemas de vigilancia y situación epidemiológica. Entre las dificultades de la estratificación del riesgo se destaca la de generación sistemática de datos con una cobertura y calidad adecuadas.
UNASSIGNED: Las estrategias de estratificación del riesgo de transmisión del sarampión siguen sin estar, al parecer, muy extendidas, en especial a nivel local. Cabe reiterar la necesidad de fomentar la capacitación de recursos humanos para procesar e interpretar los análisis de riesgo en las operaciones habituales de los servicios de vigilancia.

OBJECTIVE: To analyse spatial-temporal changes and spatial association of homicide rates with violence, sociodemographic, public security and human rights indicators in Brazilian municipalities.
METHODS: An ecological study using homicide estimates from the Global Burden of Disease and population from the Brazilian Ministry of Health, 2000 to 2018. The explanatory variables come from the systems of mortality, notifications of violence and security, and the Brazilian Institute of Geography and Statistics.
METHODS: Moran indices and maps identified clusters of high and low risk for homicides in three trienniums (p < 0.05). Multivariate linear and spatial regressions estimated explanatory factors\' contributions for the last triennium.
RESULTS: Municipalities with high rates of homicides (>34/100,000) doubled, reaching 21.5 %. Those rates were concentrated in big cities, and increased in smaller municipalities. Increases in critical areas were found in the Northeast and North regions: more than 40 % in the states of Sergipe, Bahia, Ceará, Rio Grande do Norte and Roraima. Decreases occurred in the Southeast and Midwest regions: more than 35 % in São Paulo and Rio de Janeiro states. The spatial model, with an 18.9 % higher R2 (0.706), showed a positive association for records of violence, Blacks, low-level education, municipalities >50,000 inhabitants and municipalities with homicide and municipal police.
CONCLUSIONS: An increase in and the interiorisation of homicide risk areas in Brazil was observed, with displacement among regions (from the Southeast to the North/Northeast). The level of violence was the main explanatory factor for homicides. Territorial space proved to be important to understand and prevent lethal crime.

In research assessing the effect of an intervention or exposure, a key secondary objective often involves assessing differential effects of this intervention or exposure in subgroups of interest; this is often referred to as assessing effect modification or heterogeneity of treatment effects (HTE). Observed HTE can have important implications for policy, including intervention strategies (e.g., will some patients benefit more from intervention than others?) and prioritizing resources (e.g., to reduce observed health disparities). Analysis of HTE is well understood in studies where the independent unit is an individual. In contrast, in studies where the independent unit is a cluster (e.g., a hospital or school) and a cluster-level outcome is used in the analysis, it is less well understood how to proceed if the HTE analysis of interest involves an individual-level characteristic (e.g., self-reported race) that must be aggregated at the cluster level. Through simulations, we show that only individual-level models have power to detect HTE by individual-level variables; if outcomes must be defined at the cluster level, then there is often low power to detect HTE by the corresponding aggregated variables. We illustrate the challenges inherent to this type of analysis in a study assessing the effect of an intervention on increasing COVID-19 booster vaccination rates at long-term care centers.

UNASSIGNED: To investigate the relationship between the prevalence of schistosomiasis and soil-transmitted helminthiasis with variables related to access to water, sanitation and solid waste in Latin American and Caribbean (LAC) countries.
UNASSIGNED: A systematic review was performed in the LILACS, PubMed, Web of Science, and SciELO databases. Studies published between 1950 and August 2021, with an ecological design and a focus on population groups (states, municipalities and/or districts), having the prevalence of infection by Schistosoma mansoni, Ancylostoma sp., Necator americanus, Ascaris lumbricoides or Trichuris trichiura as primary variable and access to water, sewage and/or solid waste as explanatory variables were included. Open access articles with full text available in English, Spanish, or Portuguese were considered. The risk of bias and the quality of the studies were assessed according to the Joanna Briggs Institute manual.
UNASSIGNED: Of 2 714 articles, nine were eligible, published between 1994 and 2021 and covering 22 LAC countries and 14 350 municipalities. All articles had moderate methodological quality. Environmental variables indicated an association between water supply and solid waste collection with schistosomiasis; water supply with ascariasis, trichuriasis and hookworm; and sewage with ascariasis and hookworm. Except for one article, which had regional coverage for LAC, all the others were developed in Brazil.
UNASSIGNED: There is a clear need to expand research on the association between household and collective health conditions and parasitic diseases for all endemic countries in LAC to support environmental strategies to control these diseases.
UNASSIGNED: Investigar la relación entre la prevalencia de esquistosomiasis y geohelmintiasis y las variables de acceso al agua, el saneamiento y el manejo de residuos sólidos en los países de América Latina y el Caribe.
UNASSIGNED: Se realizó una revisión sistemática en las bases de datos LILACS, PubMed, Web of Science y SciELO. Todos los artículos fueron de calidad metodológica moderada. Se incluyeron estudios publicados entre 1950 y agosto del 2021, con diseño ecológico y atención en agregados demográficos (estados, municipios o distritos), que tuvieran como resultado principal la prevalencia de infección por Schistosoma mansoni, Ancylostoma spp., Necator americanus, Ascaris lumbricoides o Trichuris trichiura y como variable explicativa el acceso al agua, el saneamiento y el manejo de residuos sólidos. Se analizaron artículos de texto completo y acceso libre en español, inglés o portugués. El riesgo de sesgo y la calidad de los estudios se evaluaron según las normas del manual del Instituto Joanna Briggs.
UNASSIGNED: De los 2 714 artículos, hubo 9 que cumplieron con los requisitos establecidos; estos se publicaron entre 1994 y el 2021 y abarcaron 22 países y 14 350 municipios de América Latina y el Caribe. Las variables ambientales indicaron una relación del abastecimiento de agua y la recolección de residuos sólidos con la esquistosomiasis; del abastecimiento de agua con la ascariasis, la tricuriasis y la anquilostomiasis; y del saneamiento con la ascariasis y la anquilostomiasis. Con excepción de un artículo que abarcó la Región de América Latina y el Caribe, todos los demás se realizaron en Brasil.
UNASSIGNED: Es evidente la necesidad de ampliar las investigaciones sobre la relación entre las condiciones sanitarias domésticas y colectivas y las enfermedades parasitarias en todos los países de América Latina y el Caribe donde son endémicas, con el fin de formular estrategias centradas en el medio ambiente para controlar esas enfermedades.
