Mapping schistosomiasis risk landscapes and implications for disease control: A case study for low endemic areas in the Middle Paranapanema river basin, São Paulo, Brazil.

BACKGROUND: Schistosomiasis, a chronic parasitic disease, remains a public health issue in tropical and subtropical regions, especially in low and moderate-income countries lacking assured access to safe water and proper sanitation. A national prevalence survey carried out by the Brazilian Ministry of Health from 2011 to 2015 found a decrease in human infection rates to 1%, with 19 out of 26 states still classified as endemic areas. There is a risk of schistosomiasis reemerging as a public health concern in low-endemic regions. This study proposes an integrated landscape-based approach to aid surveillance and control strategies for schistosomiasis in low-endemic areas. METHODOLOGY/PRINCIPAL FINDINGS: In the Middle Paranapanema river basin, specific landscapes linked to schistosomiasis were identified using a comprehensive methodology. This approach merged remote sensing, environmental, socioeconomic, epidemiological, and malacological data. A team of experts identified ten distinct landscape categories associated with varying levels of schistosomiasis transmission potential. These categories were used to train a supervised classification machine learning algorithm, resulting in a 92.5% overall accuracy and a 6.5% classification error. Evaluation revealed that 74.6% of collected snails from water collections in five key municipalities within the basin belonged to landscape types with higher potential for S. mansoni infection. Landscape connectivity metrics were also analysed. CONCLUSIONS/SIGNIFICANCE: This study highlights the role of integrated landscape-based analyses in informing strategies for eliminating schistosomiasis. The methodology has produced new schistosomiasis risk maps covering the entire basin. The region's low endemicity can be partly explained by the limited connectivity among grouped landscape-units more prone to triggering schistosomiasis transmission. Nevertheless, changes in social, economic, and environmental landscapes, especially those linked to the rising pace of incomplete urbanization processes in the region, have the potential to increase risk of schistosomiasis transmission. This study will help target interventions to bring the region closer to schistosomiasis elimination.

[Dynamics of regionalization and repercussions of gaps in care on health marketing in remote rural municipalities]. / Dinâmica da regionalização e repercussões dos vazios assistenciais na comercialização da saúde em municípios rurais remotos.

This article analyzed the dynamics of regionalization in municipalities within hinterlands and the possible implications of gaps in care for the marketing of health. This is a multiple case study with a qualitative approach, involving 76 semi-structured interviews with municipal, regional, and state managers. The results show that, particularly in the Northern states, the regional scheme did not reflect the social dynamics of the populations and created inadequate flows and unwanted routes. The municipal political agenda often prioritized interests other than that of regionalization, and rural problems did not mobilize managers to build specific regional planning. Parliamentary amendments were essential for investment in healthcare and the managers pointed to clientelistic relationships to obtain such resources, often conditioned by political-ideological alignment. The scarcity of public services favored dependence on the private sector and the commercialization of health in different situations. The great distances and the lack of public services in municipalities in the hinterland made the local public health system offer eminently dependent on contracts with private providers who negotiated on a retail basis or via service packages. Lastly, in the wake of unmet needs and gaps in care in remote rural municipalities, players in the healthcare market ₋ companies supplying inputs, consultants, healthcare professionals, and transportation services ₋ filled the gaps in public provision, sometimes controlling prices, supply and availability of services.

Analisam-se a dinâmica da regionalização em municípios rurais remotos e as possíveis implicações dos vazios assistenciais na comercialização da saúde. Trata-se de um estudo de casos múltiplos, com abordagem qualitativa, por meio de 76 entrevistas semiestruturadas com gestores municipais, regionais e estaduais. Os resultados revelam que, particularmente nos estados da Região Norte, o desenho regional não repercutia a dinâmica social das populações e criava fluxos inadequados e rotas indesejadas. A agenda política municipal priorizava, muitas vezes, interesses díspares à regionalização e as questões da ruralidade não mobilizavam os gestores para a construção de um planejamento regional específico. Emendas parlamentares ocupavam um lugar imprescindível para o investimento em saúde e os gestores apontaram relações clientelistas para obter tais recursos, condicionada e corriqueiramente, pelo alinhamento político-ideológico. A escassez de serviços públicos favorecia a dependência do setor privado e a comercialização da saúde em diferentes situações. As grandes distâncias e a ausência de serviços públicos nas proximidades dos municípios rurais remotos tornavam a oferta do Sistema Único de Saúde (SUS) local eminentemente dependente do contrato com prestadores privados que negociavam no varejo ou por meio de pacotes de serviços. Por fim, na esteira das necessidades não atendidas e dos vazios assistenciais, nos municípios rurais remotos, agentes do mercado da saúde - empresas de fornecimento de insumos, consultorias, profissionais de saúde e serviços de transporte - ocupavam as brechas da provisão pública, algumas vezes controlando preços, oferta e disponibilidade dos serviços.

Se analizan las dinámicas de la regionalización en municipios rurales remotos y las posibles implicaciones de las brechas de la atención en la comercialización de la salud. Se trata de un estudio de caso múltiple, con enfoque cualitativo, que realizó 76 entrevistas semiestructuradas a los gestores del municipio, de la región y del estado. Los resultados mostraron que, principalmente en los estados de la Región Norte, el diseño regional no reflejó la dinámica social de las poblaciones y creó flujos inadecuados y rutas indeseables. La agenda política municipal frecuentemente priorizó intereses dispares a la regionalización y los temas de ruralidad no movilizaron a los gestores para construir una planificación regional específica. Las enmiendas parlamentarias fueron esenciales para invertir en sanidad, y los gestores señalaron las relaciones clientelares para obtener estos recursos, muchas veces condicionadas por el alineamiento político-ideológico. La escasez de servicios públicos favoreció la dependencia del sector privado y la comercialización de la salud en diferentes situaciones. Las grandes distancias y la falta de servicios públicos en las cercanías de municipios rurales remotos hicieron que la oferta del Sistema Único de Salud local dependiera eminentemente del contrato con proveedores privados que negociaban al por menor o mediante paquetes de servicios. Finalmente, ante las necesidades no cumplidas y las brechas de atención, en los municipios rurales remotos, los agentes del mercado de la salud (empresas proveedoras de insumos, consultorías, profesionales de la salud y servicios de transporte) ocuparon las brechas en la prestación pública mediante muchas veces el control de los precios, de la oferta y de la disponibilidad de los servicios.

Trend of incompleteness of the race/color variable in hospitalizations due to COVID-19 whose outcome was death in Brazil, 2020-2022.

OBJECTIVE: To analyze the incompleteness and trend of incompleteness of the race/color variable in hospitalizations due to COVID-19 whose outcome was death, in Brazil, between April 2020 and April 2022. METHODS: Ecological time series study on the incompleteness of the race/color variable in hospitalizations due to COVID-19 whose outcome was death in Brazil, its macro-regions and Federative Units (FU), by joinpoint regression, calculation of Monthly Percent Change (MPC) and Average Monthly Percent Change (AMPC), based on data from the Hospital Information System of the Unified Health System (SIH/SUS). RESULTS: The incompleteness of the race/color variable in COVID-19 hospitalizations with a death outcome in Brazil was 25.85%, considered poor. All regions of the country had a poor degree of incompleteness, except for the South, which was considered regular. In the period analyzed, the joinpoint analysis revealed a stable trend in the incompleteness of the race/color variable in Brazil (AMPC = 0.54; 95%CI: -0.64 to 1.74; p = 0.37) and in the Southeast (AMPC = -0.61; 95%CI: -3.36 to 2.22; p = 0.67) and North (AMPC = 3.74; 95%CI: -0.14 to 7.78; p = 0.06) regions. The South (AMPC = 5.49; 95%CI: 2.94 to 8.11; p = 0.00002) and Northeast (AMP = 2.50; 95%CI: 0.77 to 4.25; p = 0.005) regions showed an increase in the incompleteness trend, while the Midwest (AMPC = -2.91 ; 95%CI: -5.26 to -0.51; p = 0.02) showed a downward trend. CONCLUSION: The proportion of poor completeness and the stable trend of incompleteness show that there was no improvement in the quality of filling in the race/color variable during the COVID-19 pandemic in Brazil, a fact that may have increased health inequalities for the black population and made it difficult to plan strategic actions for this population, considering the pandemic context. The results found reinforce the need to encourage discussion on the subject, given that the incompleteness of health information systems increases inequalities in access to health services and compromises the quality of health data.

Implementation of public health consortiums and regional polyclinics in Bahia state, Brazil. / Implantação de consórcios públicos de saúde e policlínicas regionais na Bahia, Brasil.

Public Health Consortiums (PHC) in Brazil represent a strategy to enhance regionalization in the Public Health Care System (SUS in Portuguese) and State/interstate/intermunicipal cooperation. The establishment of regional polyclinics aims to improve access to services with greater technological concentration and closer to users' homes. This study specifically aims to analyze the process of creating PHC and regional polyclinics in Bahia State, based on documental analysis, identifying aspects related to entering the political agenda that facilitate and hinder, the role of state administration, specificities of the composition of these PHC and regional polyclinics. A documental analysis was carried out of the minutes of the Comissão Intergestores Bipartite (CIB-BA) [Bipartite Administrative Commission] from 2015 to 2018 and of constitutive documents of the consortiums established in this state. The Ceará State experience inspired the creation of consortiums in Bahia, especially the structuring of polyclinics. Municipal administrators demonstrated a favorable position regarding the potential of consortiums with cooperation among municipalities. The role of the state government proved to be a facilitating condition, whereas the maintenance of the municipal counterpart in finance constituted a hindering element. The consortiums contributed to the regionalization of health in the state as well as expansion of access to specialized care.

Os consórcios públicos de saúde (CPS) representam uma estratégia para potencializar a regionalização no SUS e a cooperação interfederativa. A implantação de policlínicas regionais visa melhorar o acesso a serviços de maior densidade tecnológica, mais próximos ao município de origem dos usuários. Este estudo objetiva analisar o processo de implantação dos consórcios públicos de saúde e das policlínicas regionais na Bahia, com base em análise documental, identificando aspectos facilitadores e dificultadores relativos à entrada na agenda política, ao papel da gestão estadual e às especificidades da composição dos CPS e das policlínicas regionais no estado da Bahia. Realizou-se análise documental das atas da Comissão Intergestores Bipartite dos anos de 2015 a 2018 e de documentos constitutivos dos consórcios implantados na Bahia. A experiência do Ceará inspirou a criação dos consórcios na Bahia, sobretudo na estruturação das policlínicas. Verificou-se posicionamento favorável dos gestores municipais acerca da potencialidade do consórcio na cooperação entre municípios. A atuação do governo do estado revelou-se condição facilitadora, e a manutenção da contrapartida municipal no financiamento, como elemento dificultador. Os consórcios contribuíram para a regionalização da saúde no estado e a ampliação do acesso à atenção especializada.

Surveillance of TB-HIV coinfection in Brazil: a space-time approach.

OBJECTIVE: To identify the epidemiological, spatial, and temporal pattern of TB-HIV coinfection in Brazil during the period from 2001 to 2020. METHODS: Ecological study using space-time analysis techniques. It included cases of TB-HIV coinfection registered in Brazil from 2001 to 2020. The temporal trend analysis was performed using segmented regression by Joinpoint regression. For spatial analysis, Moran indices were calculated and choropleth maps were produced using TerraView and QGIS software. RESULTS: A stable temporal trend was observed in the incidence rates of TB-HIV coinfection in Brazil during the analyzed period. In addition, high-risk areas for coinfection located in states in the North, Southeast, South, and Midwest regions were identified. CONCLUSION: There was stability in the incidence of TB-HIV coinfection in Brazil over the last 20 years and heterogeneous geographic distribution of risk areas for the condition.

The Simplified Medication Adherence Questionnaire: validation of a Brazilian-Portuguese version in hypertensive adults.

Background: Self-reported adherence scales are widely used in research and practice because they are low in cost and easy to apply. A free version in Brazilian-Portuguese of the Simplified Medication Adherence Questionnaire (SMAQ) can be a useful alternative for determining the adherent behavior of hypertensive patients. Purpose: To translate and evaluate the psychometric properties of the Brazilian-Portuguese version of the SMAQ therapeutic adherence scale for patients with arterial hypertension. Patients and methods: A multicenter, cross-sectional study was conducted in five outpatient units in Maceió-AL and Aracaju-SE between January and July 2019. A total of 117 patients aged over 18 years using antihypertensive drugs were recruited. The cross-cultural adaptation followed international methodological recommendations. Internal consistency (Cronbach's alpha) was tested as a reliability parameter. Criterion and construct validity were verified by concurrent validation, exploratory factor analysis (EFA), and validation by known groups. Results: The participants had a mean age of 56.6 years (SD = 10.7 years); most were female (72.6%). The mean number of antihypertensives prescribed per patient was 1.87 (SD = 0.87). There were 79.5% (n = 86) of patients considered non-adherent. Internal consistency was satisfactory (Cronbach's alpha = 0.63). A satisfactory correlation coefficient was verified with the Morisky-Green-Levine test as an external criterion (r = 0.56, p < 0.001). The scale's sensitivity measured through known group validity was 75.3%, specificity 29.5%, positive predictive value 63.9%, and negative predictive value 41.9%. We identified two factors of the instrument's construct from EFA: specific medication-taking behaviors and barriers to adherence. The initial KMO measure of sampling adequacy was 0.691, and Bartlett's test of sphericity was significant (χ2 = 118.342, p < 0.001). Conclusion: The Brazilian-Portuguese version of the SMAQ scale proved valid and reliable for determining adherence to the pharmacotherapy in hypertensive patients. It showed more ability to detect non-adherent patients but with low specificity, possibly influenced by high social desirability.

Aerobic exercise attenuates dysautonomia, cardiac diastolic dysfunctions, and hemodynamic overload in female mice with atherosclerosis.

Cardiovascular risk increases during the aging process in women with atherosclerosis and exercise training is a strategy for management of cardiac risks in at-risk populations. Therefore, the aims of this study were to evaluate: (1) the influence of the aging process on cardiac function, hemodynamics, cardiovascular autonomic modulation, and baroreflex sensitivity in females with atherosclerosis at the onset of reproductive senescence; and (2) the impact of exercise training on age-related dysfunctions in this model. Eighteen Apolipoprotein-E knockout female mice were divided equally into young (Y), middle-aged (MA), and trained middle-aged (MAT). Echocardiographic exams were performed to verify cardiac morphology and function. Cannulation for direct recording of blood pressure and heart rate, and analysis of cardiovascular autonomic modulation, baroreflex sensitivity were performed. The MA had lower cardiac diastolic function (E'/A' ratio), and higher aortic thickness, heart rate and mean arterial pressure, lower heart rate variability and baroreflex sensitivity compared with Y. There were no differences between Y and MAT in these parameters. Positive correlation coefficients were found between aortic wall thickness with hemodynamics data. The aging process causes a series of deleterious effects such as hemodynamic overload and dysautonomia in female with atherosclerosis. Exercise training was effective in mitigating aged-related dysfunctions.

Resistance training maintains physical function but does not prevent changes in body composition and biochemical markers after detraining in aging adults.

OBJECTIVE: The objective of the present study was to analyze the effects of 10 weeks of resistance training (RT) and subsequent 4 weeks of detraining on physical function, body composition, and biochemical markers in aging adults. METHODS: The study sample was selected by convenience and consisted of 12 women with a mean age of 58 ± 7 years. Physical function [Latin-American Group of Development for Maturity (GDLAM) general index], body composition, total and fractional cholesterol, triglycerides, and glycemia were assessed before and after RT (10 weeks) and detraining (4 weeks). RESULTS: After 10 weeks of RT, there were improvements in fat-free mass (39.1 ± 4.2 vs. 39.9 ± 4.4 kg; p < 0.05 and d = 0.2), fat mass (39.9 ± 6.3% vs. 38.7 ± 6.4%; p < 0.05 and d = -0.2), conicity index (1.47 ± 0.07 vs. 1.43 ± 0.06; p = 0.001 and d = -0.6), and physical function (GDLAM index [27.2 ± 5.5 vs. 25.0 ± 4.7; p = 0.001 and d = -0.4]). Significant improvements were also found in total cholesterol (271.8 ± 75.7 vs. 217.2 ± 52.2 mg/dL; p < 0.01 and d = -0.8), LDL-cholesterol (196.5 ± 61.6 vs. 159.3 ± 38.5 mg/dL; p < 0.01 and d = -0.7), HDL-cholesterol (53.1 ± 7.3 vs. 64.3 ± 23.7 mg/dL; p < 0.05 and d = 0.7), and triglycerides (165.8 ± 32.6 vs. 139.9 ± 46.6 mg/dL; p = 0.001 and d = -0.6). After the detraining period, all benefits in physical function were successfully maintained. CONCLUSION: RT provided benefits in physical function, body composition, and biochemical markers in aging adults. However, 4-week detraining impaired body composition and biochemical markers in the investigated sample.

Scorpion envenomation in Brazil and its relationship with the social determinants of health: A population-based ecological study.

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.

Machine learning algorithms to predict outcomes in children and adolescents with COVID-19: A systematic review.

BACKGROUND AND OBJECTIVES: We aimed to analyze the study designs, modeling approaches, and performance evaluation metrics in studies using machine learning techniques to develop clinical prediction models for children and adolescents with COVID-19. METHODS: We searched four databases for articles published between 01/01/2020 and 10/25/2023, describing the development of multivariable prediction models using any machine learning technique for predicting several outcomes in children and adolescents who had COVID-19. RESULTS: We included ten articles, six (60 % [95 % confidence interval (CI) 0.31 - 0.83]) were predictive diagnostic models and four (40% [95 % CI 0.170.69]) were prognostic models. All models were developed to predict a binary outcome (n= 10/10, 100 % [95 % CI 0.72-1]). The most frequently predicted outcome was disease detection (n=3/10, 30% [95 % CI 0.11-0.60]). The most commonly used machine learning models in the studies were tree-based (n=12/33, 36.3% [95 % CI 0.17-0.47]) and neural networks (n=9/27, 33.2% [95% CI 0.15-0.44]). CONCLUSION: Our review revealed that attention is required to address problems including small sample sizes, inconsistent reporting practices on data preparation, biases in data sources, lack of reporting metrics such as calibration and discrimination, hyperparameters and other aspects that allow reproducibility by other researchers and might improve the methodology.

The Microbiota-Gut-Brain Axis in Metabolic Syndrome and Sleep Disorders: A Systematic Review.

BACKGROUND: Over recent decades, a growing body of evidence has emerged linking the composition of the gut microbiota to sleep regulation. Interestingly, the prevalence of sleep disorders is commonly related to cardiometabolic comorbidities such as diabetes, impaired lipid metabolism, and metabolic syndrome (MetS). In this complex scenario, the role of the gut-brain axis as the main communicating pathway between gut microbiota and sleep regulation pathways in the brain reveals some common host-microbial biomarkers in both sleep disturbances and MetS. As the biological mechanisms behind this complex interacting network of neuroendocrine, immune, and metabolic pathways are not fully understood yet, the present systematic review aims to describe common microbial features between these two unrelated chronic conditions. RESULTS: This systematic review highlights a total of 36 articles associating the gut microbial signature with MetS or sleep disorders. Specific emphasis is given to studies evaluating the effect of dietary patterns, dietary supplementation, and probiotics on MetS or sleep disturbances. CONCLUSIONS: Dietary choices promote microbial composition and metabolites, causing both the amelioration and impairment of MetS and sleep homeostasis.

Social movements and the genesis of LGBT health policy in Bahia, Brazil (1979-2014): initial disputes and possible alternatives. / Os movimentos sociais e a gênese de propostas para a saúde da população LGBT na Bahia, Brasil (1979-2014): disputas iniciais e alternativas possíveis.

We conducted a socio-historical study covering the period 1979-2014 to explore the genesis of LGBT health policy in Bahia, Brazil, drawing on Pinell's theoretical framework for the sociological analysis of public policy. To analyze the social space, we investigated the trajectories of the agents involved in policy formulation and the relations between these agents and the national social space and field of State power. The agents were predominantly from the scientific, human rights, sexual rights, feminism and AIDS fields, and had a high level of bureaucratic and militant capital, meaning they were well-versed in LGBT health issues. The historical conditions of possibility underlying the formulation of LGBT health policy included the formalization of the State Technical Committee on LGBT Health in 2014, in an effort to improve access to comprehensive health care for vulnerable groups; and the Bahia without Homophobia plan, which helped expand dialogue around with civil society and social movements and address the main criticisms of policy making.

Com o objetivo de descrever a gênese de propostas para a saúde da população de LGBT na Bahia, foi realizado um estudo sócio histórico entre 1979 e 2014. Adotou-se as proposições de Patrice Pinell para a análise sociológica de políticas públicas. A análise do espaço social compreendeu a identificação das trajetórias dos agentes envolvidos com as propostas no estado da Bahia e as relações entre esses agentes e o espaço social nacional, assim como, o campo do poder do Estado. Na Bahia, destacaram-se agentes com trajetórias vinculadas ao campo científico, dos direitos humanos, dos direitos sexuais, do feminismo e do espaço AIDS, com alto capital burocrático e militante, que propiciou aproximação às questões relacionadas a saúde LGBT local. As condições de possibilidade que permitiram a formulação de propostas políticas baseadas na integralidade e na universalidade da atenção à saúde foram a formalização do Comitê Técnico Estadual de Saúde Integral LGBT da Bahia, em 2014, onde buscou-se ampliar a Atenção Integral à Saúde voltada às populações de maior vulnerabilidade; e o Plano Bahia sem homofobia, que permitiu ampliar o diálogo com a sociedade civil e os movimentos sociais e abarcar as principais críticas para a formulação de propostas políticas.

Evidences of differential methylation in the genome during development in the cactophilic Drosophila species.

DNA methylation with 5-methylcytosine (5mC) has been reported in the genome of several eukaryotes, with marked differences between vertebrates and invertebrates. DNA methylation is poorly understood as its role in evolution in insects. Drosophila gouveai (cluster Drosophila buzzatii) presents larvae that develop obligatorily in necrotic tissues of cacti in nature, with the distribution of populations in South America, and plasticity of phenotypes in insect-plant interaction. We characterize organisms at developmental stages and analyze variations at multiple methylation-sensitive loci in pupae, and adult flies using methylation sensitive amplification polymorphism. We obtained 326 loci with CCGG targets in the genome of D. gouveai. Genomic regions with molecular lengths from 100 to 700 pb were most informative about methylation states. Multiple loci show differences in methylation-sensitive sites (MSL) concerning developmental stages, such as in pupae (MSL = 40), female reproductive tissue (MSL = 76), and male reproductive tissues (MSL = 58). Our results are the first evidence of genome-wide methylation in D. gouveai organisms.

Quality of Nursing Care Perceived by People With HIV in Brazil: A Cross-Sectional Study.

ABSTRACT: We evaluated the quality of care provided by the nursing team within specialized care services (SCS) from the perspective of persons with HIV (PWH). A cross-sectional study was conducted in 25 SCS selected by a single-stage cluster sampling in 21 municipalities in Brazil. Systematic sampling was performed between October 2019 and March 2020 in the reception areas of SCS locations to choose the study population ( N = 377). The adapted and validated Quality of Care Through the Patient's Eyes-HIV (QUOTE-HIV) questionnaire was used to measure the quality of perceived care, and the Mann-Whitney test to compare the scores between men and women. Of the 377 PWH, most were women (57.71%), Black or Brown (85.9%), heterosexual (67.1%), and cisgendered (96.0%); the mean age was ≥30 years (76.1%). Users' evaluation of the care provided by SCS according to scores of importance and performance of the QUOTE-HIV instrument ranged from 5.60 to 8.95 and 0.03 to 0.76, respectively. The perception of PWH about the quality of care provided by the nursing team in SCS suggests that there are opportunities to improve.

Características clínicas e fatores de risco que afetam a mortalidade de crianças e adolescentes com COVID-19: um estudo de coorte retrospectivo de âmbito nacional utilizando aprendizado de máquina / Clinical characteristics and risk factors affecting mortality of children and adolescents with COVID-19: a nationwide retrospective cohort study using machine learning

A pandemia de COVID-19 impulsionou a aplicação de tecnologias digitais avançadas, como a inteligência artificial (IA), para prever a mortalidade em pacientes adultos. No entanto, o desenvolvimento de modelos de aprendizado de máquina (ML) para prever desfechos em crianças e adolescentes com COVID-19 ainda é limitado. Este estudo teve como objetivo avaliar o desempenho de múltiplos modelos de aprendizado de máquina na previsão de mortalidade entre pacientes pediátricos hospitalizados com COVID-19 e analisar sua viabilidade quando aplicados a grandes bases de dados. Neste estudo de coorte, utilizamos o banco de dados SIVEP-Gripe, um recurso público mantido pelo Ministério da Saúde, para monitorar a síndrome respiratória aguda grave (SRAG) no Brasil. Para criar subconjuntos destinados ao treinamento e teste dos modelos de aprendizado de máquina (ML), dividimos o banco de dados primário em três partes. Com esses subconjuntos, desenvolvemos e treinamos 12 algoritmos de ML para prever os desfechos. Avaliamos o desempenho desses modelos utilizando diversas métricas, como acurácia, precisão, sensibilidade, revocação e a área sob a curva característica de operação do receptor (AUC). Entre as 37 variáveis examinadas, 24 foram identificadas como potenciais indicadoras de mortalidade, conforme determinado pelo teste de independência do qui-quadrado. O algoritmo de regressão logística (LR) obteve o maior desempenho, com uma acurácia de 92,5% e uma AUC de 80,1% no conjunto de dados otimizado. Os algoritmos de Gradient Boosting Classifier (GBC) e Adaptive Boosting (ADA) apresentaram resultados semelhantes aos do algoritmo LR. Nosso estudo também revelou que a saturação de oxigênio reduzida na linha de base, a presença de comorbidades e a idade avançada foram os fatores mais relevantes na previsão de mortalidade em crianças e adolescentes hospitalizados. O uso de modelos de ML pode ser uma ferramenta valiosa na tomada de decisões clínicas e na implementação de estratégias de gestão de pacientes baseadas em evidências, o que pode melhorar os desfechos dos pacientes e a qualidade geral dos cuidados médicos. Os modelos LR, GBC e ADA demonstraram eficiência na previsão precisa de mortalidade em pacientes pediátricos com COVID-19.

The COVID-19 pandemic has catalyzed the application of advanced digital technologies such as artificial intelligence (AI) to predict mortality in adult patients. However, the development of machine learning (ML) models for predicting outcomes in children and adolescents with COVID-19 remains limited. This study aimed to evaluate the performance of multiple machine learning models in forecasting mortality among hospitalized pediatric COVID-19 patients and assess their feasibility when applied to large-scale datasets. In this cohort study, we used the SIVEP-Gripe dataset, a public resource maintained by the Ministry of Health, to track severe acute respiratory syndrome (SARS) in Brazil. To create subsets for training and testing the machine learning (ML) models, we divided the primary dataset into three parts. Using these subsets, we developed and trained 12 ML algorithms to predict the outcomes. We assessed the performance of these models using various metrics such as accuracy, precision, sensitivity, recall, and area under the receiver operating characteristic curve (AUC). Among the 37 variables examined, 24 were found to be potential indicators of mortality, as determined by the chi-square test of independence. The LR algorithm achieved the highest performance, with an accuracy of 92.5% and an AUC of 80.1%, on the optimized dataset. GBC and ADA closely followed the LR algorithm, producing similar results. Our study also revealed that baseline reduced oxygen saturation, presence of comorbidities, and older age were the most relevant factors in predicting mortality in hospitalized children and adolescents. The use of ML models can be an asset in making clinical decisions and implementing evidence-based patient management strategies, which can enhance patient outcomes and overall quality of medical care. LR, GBC, and ADA models have demonstrated efficiency in accurately predicting mortality in COVID-19 pediatric patients.

Dinâmica da regionalização e repercussões dos vazios assistenciais na comercialização da saúde em municípios rurais remotos / Dynamics of regionalization and repercussions of gaps in care on health marketing in remote rural municipalities / Dinámicas de la regionalización y repercusiones de las brechas de atención en la comercialización de la salud en municipios rurales remotos

Analisam-se a dinâmica da regionalização em municípios rurais remotos e as possíveis implicações dos vazios assistenciais na comercialização da saúde. Trata-se de um estudo de casos múltiplos, com abordagem qualitativa, por meio de 76 entrevistas semiestruturadas com gestores municipais, regionais e estaduais. Os resultados revelam que, particularmente nos estados da Região Norte, o desenho regional não repercutia a dinâmica social das populações e criava fluxos inadequados e rotas indesejadas. A agenda política municipal priorizava, muitas vezes, interesses díspares à regionalização e as questões da ruralidade não mobilizavam os gestores para a construção de um planejamento regional específico. Emendas parlamentares ocupavam um lugar imprescindível para o investimento em saúde e os gestores apontaram relações clientelistas para obter tais recursos, condicionada e corriqueiramente, pelo alinhamento político-ideológico. A escassez de serviços públicos favorecia a dependência do setor privado e a comercialização da saúde em diferentes situações. As grandes distâncias e a ausência de serviços públicos nas proximidades dos municípios rurais remotos tornavam a oferta do Sistema Único de Saúde (SUS) local eminentemente dependente do contrato com prestadores privados que negociavam no varejo ou por meio de pacotes de serviços. Por fim, na esteira das necessidades não atendidas e dos vazios assistenciais, nos municípios rurais remotos, agentes do mercado da saúde - empresas de fornecimento de insumos, consultorias, profissionais de saúde e serviços de transporte - ocupavam as brechas da provisão pública, algumas vezes controlando preços, oferta e disponibilidade dos serviços.

This article analyzed the dynamics of regionalization in municipalities within hinterlands and the possible implications of gaps in care for the marketing of health. This is a multiple case study with a qualitative approach, involving 76 semi-structured interviews with municipal, regional, and state managers. The results show that, particularly in the Northern states, the regional scheme did not reflect the social dynamics of the populations and created inadequate flows and unwanted routes. The municipal political agenda often prioritized interests other than that of regionalization, and rural problems did not mobilize managers to build specific regional planning. Parliamentary amendments were essential for investment in healthcare and the managers pointed to clientelistic relationships to obtain such resources, often conditioned by political-ideological alignment. The scarcity of public services favored dependence on the private sector and the commercialization of health in different situations. The great distances and the lack of public services in municipalities in the hinterland made the local public health system offer eminently dependent on contracts with private providers who negotiated on a retail basis or via service packages. Lastly, in the wake of unmet needs and gaps in care in remote rural municipalities, players in the healthcare market ₋ companies supplying inputs, consultants, healthcare professionals, and transportation services ₋ filled the gaps in public provision, sometimes controlling prices, supply and availability of services.

Se analizan las dinámicas de la regionalización en municipios rurales remotos y las posibles implicaciones de las brechas de la atención en la comercialización de la salud. Se trata de un estudio de caso múltiple, con enfoque cualitativo, que realizó 76 entrevistas semiestructuradas a los gestores del municipio, de la región y del estado. Los resultados mostraron que, principalmente en los estados de la Región Norte, el diseño regional no reflejó la dinámica social de las poblaciones y creó flujos inadecuados y rutas indeseables. La agenda política municipal frecuentemente priorizó intereses dispares a la regionalización y los temas de ruralidad no movilizaron a los gestores para construir una planificación regional específica. Las enmiendas parlamentarias fueron esenciales para invertir en sanidad, y los gestores señalaron las relaciones clientelares para obtener estos recursos, muchas veces condicionadas por el alineamiento político-ideológico. La escasez de servicios públicos favoreció la dependencia del sector privado y la comercialización de la salud en diferentes situaciones. Las grandes distancias y la falta de servicios públicos en las cercanías de municipios rurales remotos hicieron que la oferta del Sistema Único de Salud local dependiera eminentemente del contrato con proveedores privados que negociaban al por menor o mediante paquetes de servicios. Finalmente, ante las necesidades no cumplidas y las brechas de atención, en los municipios rurales remotos, los agentes del mercado de la salud (empresas proveedoras de insumos, consultorías, profesionales de la salud y servicios de transporte) ocuparon las brechas en la prestación pública mediante muchas veces el control de los precios, de la oferta y de la disponibilidad de los servicios.

Implantação de consórcios públicos de saúde e policlínicas regionais na Bahia, Brasil / Implementation of public health consortiums and regional polyclinics in Bahia state, Brazil

Resumo Os consórcios públicos de saúde (CPS) representam uma estratégia para potencializar a regionalização no SUS e a cooperação interfederativa. A implantação de policlínicas regionais visa melhorar o acesso a serviços de maior densidade tecnológica, mais próximos ao município de origem dos usuários. Este estudo objetiva analisar o processo de implantação dos consórcios públicos de saúde e das policlínicas regionais na Bahia, com base em análise documental, identificando aspectos facilitadores e dificultadores relativos à entrada na agenda política, ao papel da gestão estadual e às especificidades da composição dos CPS e das policlínicas regionais no estado da Bahia. Realizou-se análise documental das atas da Comissão Intergestores Bipartite dos anos de 2015 a 2018 e de documentos constitutivos dos consórcios implantados na Bahia. A experiência do Ceará inspirou a criação dos consórcios na Bahia, sobretudo na estruturação das policlínicas. Verificou-se posicionamento favorável dos gestores municipais acerca da potencialidade do consórcio na cooperação entre municípios. A atuação do governo do estado revelou-se condição facilitadora, e a manutenção da contrapartida municipal no financiamento, como elemento dificultador. Os consórcios contribuíram para a regionalização da saúde no estado e a ampliação do acesso à atenção especializada.

Abstract Public Health Consortiums (PHC) in Brazil represent a strategy to enhance regionalization in the Public Health Care System (SUS in Portuguese) and State/interstate/intermunicipal cooperation. The establishment of regional polyclinics aims to improve access to services with greater technological concentration and closer to users' homes. This study specifically aims to analyze the process of creating PHC and regional polyclinics in Bahia State, based on documental analysis, identifying aspects related to entering the political agenda that facilitate and hinder, the role of state administration, specificities of the composition of these PHC and regional polyclinics. A documental analysis was carried out of the minutes of the Comissão Intergestores Bipartite (CIB-BA) [Bipartite Administrative Commission] from 2015 to 2018 and of constitutive documents of the consortiums established in this state. The Ceará State experience inspired the creation of consortiums in Bahia, especially the structuring of polyclinics. Municipal administrators demonstrated a favorable position regarding the potential of consortiums with cooperation among municipalities. The role of the state government proved to be a facilitating condition, whereas the maintenance of the municipal counterpart in finance constituted a hindering element. The consortiums contributed to the regionalization of health in the state as well as expansion of access to specialized care.

Gestão e planejamento integrado em saúde no SUS: análise da capacidade governamental em região de saúde da Bahia / Integrated regional health management and planning in the SUS: analysis of government capacity in a health region in the state of Bahia

Resumo Este artigo objetivou analisar o grau de implantação do planejamento regional, considerando como condição traçadora os fluxos assistenciais para o câncer de colo de útero, em uma região de saúde do SUS baiano. Trata-se de um estudo avaliativo, do tipo avaliação da implantação do planejamento regionalizado em saúde, a partir de um estudo de caso da Região de Saúde de Vitória da Conquista (RSVC), Bahia. Realizaram-se 29 entrevistas com gestores e representantes da Comissão Intergestores Regional (CIR) e foram analisados 103 documentos. A matriz avaliativa subsidiou a mensuração do grau de implantação do planejamento pelos municípios, considerada incipiente, com três municípios apresentando grau intermediário (M1, M2 e M3); apenas M4 atingiu o grau avançado. Observou-se o caráter político nas tomadas de decisão persistente, preterindo-se a análise técnica e, consequentemente, não favorecendo as ações de monitoramento do acesso, que foram pontuais, e reduzindo a capacidade de controle e negociação junto aos prestadores de serviços privados. Os desafios da gestão, organização sistêmica e contexto político regional foram determinantes para a incipiente implantação do planejamento ante a incoerência entre instituições e características desfavoráveis à integração intermunicipal, sendo necessárias ações estratégicas para fortalecer a capacidade de planejamento integrado entre municípios.

Abstract This article aimed to analyze the degree of implementation of regional planning, considering care flows for cervical cancer as a defining condition, in a health region of the SUS in Bahia. This is an evaluative study, evaluating the implementation of regionalized health planning, based on a case study of the Vitória da Conquista Health Region (RSVC), state of Bahia. Twenty-nine interviews were carried out with managers and representatives of the Regional Intermanagers Commission (CIR) and 103 documents were analyzed. The evaluation matrix supported the measurement of the level of planning implementation by the municipalities, considered incipient, with three municipalities showing an intermediate level (M1, M2, and M3); only M4 reached an advanced grade. The political nature of persistent decision-making was observed, neglecting technical analysis and, consequently, not favoring access monitoring actions, which were punctual, and reducing the capacity for control and negotiation with private service providers. The challenges of management, systemic organization, and regional political context were decisive for the incipient implementation of planning given the incoherence between institutions and characteristics unfavorable to inter-municipal integration, making strategic actions necessary to strengthen the capacity for integrated planning between municipalities.

Trend of incompleteness of the race/color variable in hospitalizations due to COVID-19 whose outcome was death in Brazil, 2020-2022 / Tendência da incompletude da variável raça/cor nas internações por covid-19 cujo desfecho foi óbito no Brasil, 2020-2022

ABSTRACT OBJECTIVE To analyze the incompleteness and trend of incompleteness of the race/color variable in hospitalizations due to COVID-19 whose outcome was death, in Brazil, between April 2020 and April 2022. METHODS Ecological time series study on the incompleteness of the race/color variable in hospitalizations due to COVID-19 whose outcome was death in Brazil, its macro-regions and Federative Units (FU), by joinpoint regression, calculation of Monthly Percent Change (MPC) and Average Monthly Percent Change (AMPC), based on data from the Hospital Information System of the Unified Health System (SIH/SUS). RESULTS The incompleteness of the race/color variable in COVID-19 hospitalizations with a death outcome in Brazil was 25.85%, considered poor. All regions of the country had a poor degree of incompleteness, except for the South, which was considered regular. In the period analyzed, the joinpoint analysis revealed a stable trend in the incompleteness of the race/color variable in Brazil (AMPC = 0.54; 95%CI: -0.64 to 1.74; p = 0.37) and in the Southeast (AMPC = -0.61; 95%CI: -3.36 to 2.22; p = 0.67) and North (AMPC = 3.74; 95%CI: -0.14 to 7.78; p = 0.06) regions. The South (AMPC = 5.49; 95%CI: 2.94 to 8.11; p = 0.00002) and Northeast (AMP = 2.50; 95%CI: 0.77 to 4.25; p = 0.005) regions showed an increase in the incompleteness trend, while the Midwest (AMPC = -2.91 ; 95%CI: -5.26 to -0.51; p = 0.02) showed a downward trend. CONCLUSION The proportion of poor completeness and the stable trend of incompleteness show that there was no improvement in the quality of filling in the race/color variable during the COVID-19 pandemic in Brazil, a fact that may have increased health inequalities for the black population and made it difficult to plan strategic actions for this population, considering the pandemic context. The results found reinforce the need to encourage discussion on the subject, given that the incompleteness of health information systems increases inequalities in access to health services and compromises the quality of health data.

RESUMO OBJETIVO Analisar a incompletude e a tendência da incompletude da variável raça/cor nas internações por covid-19 cujo desfecho foi óbito, no Brasil, no período entre abril de 2020 e abril de 2022. MÉTODOS Estudo ecológico de série temporal sobre a incompletude da variável raça/cor nas internações por covid-19 cujo desfecho foi óbito no Brasil, suas macrorregiões e Unidades Federativas (UF), pela regressão por joinpoint, cálculo da Monthly Percent Change (MPC) e Average Monthly Percent Change (AMPC), a partir de dados do Sistema de Informação Hospitalar do Sistema Único de Saúde (SIH/SUS). RESULTADOS A incompletude da variável raça/cor nas internações por covid-19 cujo desfecho foi óbito no Brasil foi 25,85%, considerada ruim. Todas as regiões do país tiveram grau de incompletude ruim, exceto a Região Sul, considerada regular. No período analisado, a análise jointpoint revelou tendência de estabilidade na incompletude da variável raça/cor no Brasil (AMPC = 0,54; IC95% -0,64 a 1,74; p = 0,37) e nas regiões Sudeste (AMPC = -0,61; IC95% -3,36 a 2,22; p = 0,67) e Norte (AMPC = 3,74; IC95% -0,14 a 7,78; p = 0,06). As regiões Sul (AMPC = 5,49; IC95% 2,94 a 8,11; p = 0,00002) e Nordeste (AMPC = 2,50; IC95% 0,77 a 4,25;p = 0,005) apresentaram crescimento na tendência da incompletude, enquanto a Região Centro-Oeste (AMPC = -2,91; IC95% -5,26 a -0,51; p = 0,02) teve tendência de redução. CONCLUSÃO A proporção de preenchimento ruim e a tendência de estabilidade da incompletude revelam que não houve melhoria na qualidade de preenchimento da variável raça/cor durante o período da pandemia da covid-19 no Brasil, fato que pode ter ampliado as iniquidades em saúde para população negra e dificultado o planejamento de ações estratégias para essa população, considerando o contexto pandêmico. Os resultados encontrados reforçam a necessidade de fomentar a discussão sobre o tema, tendo em vista que a incompletude dos sistemas de informação em saúde amplia desigualdades no acesso aos serviços de saúde e compromete a qualidade dos dados em saúde.

Os movimentos sociais e a gênese de propostas para a saúde da população LGBT na Bahia, Brasil (1979-2014): disputas iniciais e alternativas possíveis / Social movements and the genesis of LGBT health policy in Bahia, Brazil (1979-2014): initial disputes and possible alternatives

Resumo Com o objetivo de descrever a gênese de propostas para a saúde da população de LGBT na Bahia, foi realizado um estudo sócio histórico entre 1979 e 2014. Adotou-se as proposições de Patrice Pinell para a análise sociológica de políticas públicas. A análise do espaço social compreendeu a identificação das trajetórias dos agentes envolvidos com as propostas no estado da Bahia e as relações entre esses agentes e o espaço social nacional, assim como, o campo do poder do Estado. Na Bahia, destacaram-se agentes com trajetórias vinculadas ao campo científico, dos direitos humanos, dos direitos sexuais, do feminismo e do espaço AIDS, com alto capital burocrático e militante, que propiciou aproximação às questões relacionadas a saúde LGBT local. As condições de possibilidade que permitiram a formulação de propostas políticas baseadas na integralidade e na universalidade da atenção à saúde foram a formalização do Comitê Técnico Estadual de Saúde Integral LGBT da Bahia, em 2014, onde buscou-se ampliar a Atenção Integral à Saúde voltada às populações de maior vulnerabilidade; e o Plano Bahia sem homofobia, que permitiu ampliar o diálogo com a sociedade civil e os movimentos sociais e abarcar as principais críticas para a formulação de propostas políticas.

Abstract We conducted a socio-historical study covering the period 1979-2014 to explore the genesis of LGBT health policy in Bahia, Brazil, drawing on Pinell's theoretical framework for the sociological analysis of public policy. To analyze the social space, we investigated the trajectories of the agents involved in policy formulation and the relations between these agents and the national social space and field of State power. The agents were predominantly from the scientific, human rights, sexual rights, feminism and AIDS fields, and had a high level of bureaucratic and militant capital, meaning they were well-versed in LGBT health issues. The historical conditions of possibility underlying the formulation of LGBT health policy included the formalization of the State Technical Committee on LGBT Health in 2014, in an effort to improve access to comprehensive health care for vulnerable groups; and the Bahia without Homophobia plan, which helped expand dialogue around with civil society and social movements and address the main criticisms of policy making.
