Resumen El objetivo de este estudio fue comparar la capacidad de obturación en conductos radiculares curvos utilizando una nueva técnica de condensación de onda continua (Termo Pack II, Easy Dental Equipments, Brasil) vs compactación lateral. El porcentaje de brechas en la obturación de los conductos radiculares mesiales de los molares mandibulares se evaluó mediante microtomografía computarizada (micro-CT). Se prepararon conductos radiculares mesiales (n=24) de molares mandibulares con un grado de curvatura entre 20° y 40° utilizando un sistema rotatorio (ProDesign Logic, Easy, Brasil) al #35, conicidad 0,05. Los conductos radiculares se obturaron utilizando un sistema de condensación de onda contínua o compactación lateral y cemento AH Plus (n=12). Se realizó un escaneo de 9 µm después de la preparación y después de la obturación usando el micro-CT SkyScan 1176. Se calculó el porcentaje volumétrico de material de obturación y vacíos (longitud total y en cada tercio del conducto radicular). Los datos se analizaron utilizando las pruebas ANOVA/Tukey y t de Student (α=0,05). Antes de las técnicas de obturación, el volumen de los conductos radiculares después de la preparación fue similar (p>0,05). Los conductos radiculares obturados con la técnica de condensación por onda contínua presentaron el menor porcentaje de vacíos y el mayor porcentaje de material de obturación en longitud total y en tercios (cervical, medio y apical) (p<0,05). Ambas técnicas no fueron capaces de llenar completamente los conductos radiculares. La técnica de condensación de onda contínua Termo Pack II promovió un mejor relleno del conducto radicular en conductos radiculares curvos en comparación con la compactación lateral.

Abstract The aim of this study was to compare the filling capacity in curved root canal using a new continuous wave of condensation technique (Termo Pack II, Easy Dental Equipments, Brazil) or lateral compaction. The percentage of voids in the filling of mesial root canals of mandibular molars was assessed by micro-computed tomography (micro-CT). Mesial root canals (n=24) of mandibular molars with a degree of curvature between 20° and 40° were prepared using rotary system (ProDesign Logic, Easy, Brazil) up to #35, .05 taper. The root canals were filled by using the continuous wave of condensation system or lateral compaction and AH Plus sealer (n=12). Scanning at 9 µm was performed after preparation and after filling by using micro-CT SkyScan 1176. The volumetric percentage of filling material and voids (total length and in each root canal third) were calculated. Data were analyzed using ANOVA/ Tukey and Student’s t tests (α=0.05). Before the filling techniques, the root canals volume after preparation was similar (p>0.05). The root canals filled by the continuous wave of condensation technique presented the lowest percentage of voids, and the greatest percentage of filling material in total length and thirds (cervical, middle and apical) (p<0.05). Both techniques were not able of completely filling the root canals. The continuous wave of condensation technique Termo Pack II promoted better root canal filling in curved root canals, when compared with lateral compaction.

ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização, baseada em evidências científicas, sobre cada tópico relacionado ao tratamento sistêmico e a apresentar os dados e recomendações resumidas durante a reunião. Todos os painelistas se reuniram para discutir os tópicos e elaborar as recomendações atualizadas. O presente documento é a versão final do manuscrito revisado, contendo as recomendações da SBH, e seu objetivo é auxiliar os profissionais de saúde, formuladores de políticas e planejadores no Brasil e na América Latina na tomada de decisões sobre o tratamento sistêmico de pacientes com CHC.

ABSTRACT BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike’s Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.

Abstract Aim In the present study, the structure of the benthic invertebrates in ponds in the presence and absence of Nile tilapia was evaluated. Methods The benthic macroinvertebrates and physicochemical parameters were analyzed for a period of eight weeks, every 15 days, in two ponds (one with fish and the other without fish). Benthic invertebrates were sampled with artificial substrate samplers, made with cheap and common materials, like expanded clay, loofah leaves and gravel. Results With the exception of turbidity, the other physical and chemical variables of water quality were within the ideal limits for tilapia farming. Despite that, there was a significant difference for all physical-chemical parameters monitored, and the average turbidity was much higher in pond with fish. The use of artificial substrate samplers for biomonitoring was effective in the colonization of several taxa in a short period of time (15 days). For benthic community metrics, organism richness, diversity and evenness were significantly higher in the pond without fish. On the other hand, the dominance of Chironomidae and the abundance of Glossiphonidae were much higher in the pond with fish. For Chironomidae, this family was dominant in both treatments, but reached a higher frequency in the pond with fish (98.49%) than in pond without fish (92.87%). The presence of sensitive families, like Leptoceridae (Order Trichoptera), was higher in the pond with no fish, as well as the metric of Ephemeroptera, Plecoptera and Trichoptera families (% EPT). Conclusions The presence of fish altered the macrobenthic community, since metrics of richness and diversity presented lower values in pond with fish.

Resumo Objetivo No presente estudo, avaliou-se a estrutura de invertebrados bentônicos em viveiros escavados na presença e ausência de tilápia do Nilo. Métodos Os macroinvertebrados bentônicos e os parâmetros físico-químicos foram analisados por um período de oito semanas, a cada 15 dias, em dois viveiros (um com peixes e outro sem peixes). Os invertebrados bentônicos foram coletados com amostradores de substrato artificial, feitos com materiais baratos e comuns, tais como argila expandida, folhas de taboa e brita. Resultados Com exceção da turbidez, as demais variáveis físicas e químicas da qualidade da água estiveram dentro dos limites ideais para o cultivo de tilápia. Apesar disso, houve diferença significativa para todos os parâmetros físico-químicos monitorados, sendo que a turbidez média foi bem maior no tanque com peixes. Para as métricas dos macroinvertebrados bentônicos, riqueza, diversidade e uniformidade de organismos foram significativamente maiores no tanque sem peixes. Por outro lado, a dominância de Chironomidae e a abundância de Glossiphonidae foram muito maiores no tanque com peixes. Para Chironomidae, esta família foi dominante em ambos os tratamentos, mas atingiu maior frequência no viveiro com peixes (98,49%) do que no viveiro sem peixes (92,87%). A presença de famílias sensíveis, como Leptoceridae (Ordem Trichoptera), foi maior no viveiro sem peixes, assim como a métrica das famílias Ephemeroptera, Plecoptera e Trichoptera (% EPT). Conclusões O uso de amostradores de substrato artificial para biomonitoramento mostrou-se eficaz na colonização de diversos táxons em um curto período de tempo (15 dias). Por fim, a presença de peixes alterou a comunidade macrobentônica, já que as métricas de riqueza e diversidade apresentaram valores mais baixos no viveiro escavado com peixes.

Abstract The aim of this study was to evaluate root canal preparation with nickel titanium rotary instruments and complementary preparation with ultrasonic tip in curved canals of mandibular molars with isthmus. Twenty–eight mesial roots of mandibular molars with curvature between 20° and 40° and presence of isthmus throughout the entire extension of the root canals were prepared using ProDesign Logic CM (PDL) up to size 40.05, or HyFlex EDM (HFEDM) up to size 40.04. Complementary preparation was performed in the isthmus region using the ultrasonic insert E18D (Helse, Istmo Diamantada). The root canals were scanned using micro–CT (SkyScan 1176) at 9 µm voxel size before and after each preparation step. Transportation, percentage of increase in volume, debris and uninstrumented surface (UNS) were evaluated. Mann Whitney, Wilcoxon, paired and non–paired t–tests were used for statistical analysis (α = 0.05). The canals prepared with PDL and HFEDM obtained similar results for all the variables assessed before using E18D (p > 0.05). E18D significantly decreased the percentage of debris and UNS values in both Groups (p < 0.05). The complementary preparations with E18D caused a smaller quantity of debris in the isthmus of the canals previously prepared with PDL in comparison with HFEDM (p < 0.05). PDL and HFEDM provided similar root canal preparation. PDL promoted a smaller quantity of Debris in the isthmus than HFEDM after using E18D. E18D significantly improved cleaning, and reduced Debris and UNS.

ABSTRACT Objective: To evaluate the axial correction capacity of the 3D brace in treating Adolescent Idiopathic Scoliosis (AIS). Methods: A retrospective study was carried out with 61 patients with AIS who obtained the 3D brace, between 2019 and 2022, in a laboratory that manufactures orthotics and orthopedic prostheses. These individuals underwent independent analysis of radiographic parameters by evaluating vertebral rotation using the Nash and Moe classification. The analyzed radiographs were taken in orthostasis before and after treatment with the 3D vest. Patients were divided into groups I and II-IV according to the Nash and Moe radiographic classification. Corrective capacity was estimated by assessing the degree of vertebral rotation before and after treatment. Results: Of the 61 patients evaluated, 36 (59%) had Nash and Moe grade I, and 25 patients grade II-IV before treatment. After treatment, 13 (21%) had grade II-IV, and 48 had grade I. Of the patients categorized as II-IV, 64% had improvement in the rotational profile. None clinical studies or radiographic parameter was associated with a change in rotational profile other than brace use (p=0.012). Conclusion: In the studied sample, treatment with the 3D vest promoted a change in vertebral rotation according to the Nash and Moe classification. The majority showed improvement in this parameter of evaluation of treatment of AIS. Level of Evidence III; Retrospective Study.

RESUMEN Objetivo: Evaluar la capacidad de corrección axial del corsé 3D en el tratamiento de la Escoliosis Idiopática del Adolescente (EIA). Métodos: Se realizó un estudio retrospectivo con 61 pacientes con EIA que obtuvieron el corsé 3D, entre 2019 y 2022, en un laboratorio que fabrica ortesis y prótesis ortopédicas. Estos individuos se sometieron a un análisis independiente de los parámetros radiográficos a través de la evaluación de la rotación vertebral utilizando la clasificación de Nash y Moe. Las radiografías analizadas se tomaron en ortostasis antes y después del tratamiento con el corsé 3D. Los pacientes se dividieron en grupo I y grupo II-IV según la clasificación radiográfica de Nash y Moe. La capacidad correctora se estimó evaluando el grado de rotación vertebral antes y después del tratamiento. Resultados: De los 61 pacientes evaluados, 36 pacientes (59%) tenían grado I de Nash y Moe, y 25 grado II-IV antes del tratamiento. Después del tratamiento, 13 (21%) tenían grado II-IV, y 48 grado I. De los pacientes categorizados como II-IV, el 64% tuvo mejoría en el perfil rotacional. Ningún parámetro clínico o radiográfico estudiado se asoció con el cambio en el perfil de rotación que no sea el uso de aparatos ortopédicos (p = 0,012). Conclusiones: En la muestra estudiada, el tratamiento con el corsé 3D promovió un cambio en la rotación vertebral según la clasificación de Nash y Moe. La mayoría mostró mejoría en este parámetro de evaluación del tratamiento de la EIA. Nivel de Evidencia III; Estudio Retrospectivo.

Esses indivíduos foram submetidos à análise independente dos parâmetros radiográficos através da avaliação da rotação vertebral pela classificação de Nash e Moe. As radiografias analisadas foram realizadas em ortostase antes e após o tratamento com o colete 3D. Os pacientes foram separados em grupo I e grupo II-IV de acordo com a classificação radiográfica de Nash e Moe. A capacidade de correção foi estimada pela avaliação do grau de rotação vertebral antes e depois do tratamento. Resultados: Dentre os 61 pacientes avaliados, 36 (59%) apresentavam grau I, e 25 pacientes grau II-IV de Nash e Moe, antes do tratamento. Após o tratamento, 13 (21%) apresentavam grau II-IV e, 48 pacientes apresentavam grau I. Dos pacientes categorizados como II-IV, 64% tiveram melhora no perfil rotacional. Nenhum parâmetro clínico ou radiográfico estudado esteve associado com a mudança no perfil rotacional além do uso do colete (p=0,012). Conclusões: Na amostra estudada, o tratamento com o colete 3D promoveu mudança na rotação vertebral pela classificação de Nash e Moe. A maioria dos pacientes apresentou melhora neste parâmetro de avaliação de tratamento da EIA. Nível de Evidência III; Estudo Retrospectivo.

ABSTRACT Objective: Evaluate the inter and intra-observer reliability of Nash and Moe’s grades, used to assess patients diagnosed with Adolescent Idiopathic Scoliosis (AIS). Methodology: Forty-seven representative x-rays of patients with AIS were randomly selected to evaluate the apical vertebral rotation (AVR) using Nash and Moe’s grades. The evaluation of the AVR was made independently in two distinct moments by two observers. The inclusion criteria in the study were a patient diagnosed with AIS and an orthostasis radiography with a good-quality image. An agreement study between the evaluations and the inter and intraobserver’s reliability was determined using Kappa’s statistics with a confidence interval of 95%. Results: The interobservers’ Kappa’s value in the first evaluation was 0,44 (CI 95%; 0,22-0,66) and 0,37 (CI 95%; 0,17-0,56) in the second. In the intraobservers’ evaluations, the Kappa’s value for examiner 1 was 0,61 (CI 95%; 0,40-0,81) and 0,46 (CI 95%; 0,22-0,70) for examiner 2. Conclusion: This study’s results demonstrated that Nash and Moe’s grades are unreliable for evaluating vertebral rotation in patients with AIS. Level of Evidence III; A Cross-Sectional Study.

Resumen Introducción: Datos de varios países del mundo sugieren que los niños con COVID-19 podrían presentar síntomas diferentes y menos graves que los adultos. Sin embargo, los patrones epidemiológicos y clínicos en este grupo poblacional son poco claros. Métodos: El presente es un estudio observacional, con una caracterización inicial transversal-analítica, y con un componente longitudinal o de seguimiento a un grupo de menores con sospecha y/o diagnóstico confirmado de COVID-19, que presentaron desenlaces como mejoría, traslado a un nivel superior de atención o defunción por sintomatología respiratoria. Los niños recibieron atención médica en el Hospital General Regional con Medicina Familiar N.° 1 (HGR C/MF N.° 1), y se les realizó prueba de reacción en cadena de la polimerasa en tiempo real (RT-PCR). Resultados: Se estudiaron 98 niños como casos sospechosos para COVID-19, a quienes se les realizó RT-PCR. Del total, 24 resultaron positivos y 74 fueron negativos. La mediana de edad de los participantes fue 64,4 meses (0 a 203 meses), 55 menores eran de sexo masculino, 59 niños tuvieron manejo ambulatorio, y de estos, 14 presentaron resultado positivo. Entre los que requirieron manejo hospitalario (39), 10 niños dieron positivo para SARS-CoV-2, 84,7% alcanzaron mejoría y fueron dados de alta, 4 fueron trasladados a hospitales de nivel superior de atención. De los 98 niños en estudio, 11 fallecieron, 7 con resultado negativo y 4 con resultado positivo para SARS-CoV-2. Conclusiones: Los principales síntomas de la población pediátrica en este estudio fueron fiebre, tos y malestar general. De los niños que fallecieron, 4 presentaron resultado positivo para SARS-CoV-2, no obstante, estos presentaban otras comorbilidades.

Abstract Introduction: Data from several countries around the world suggest that children with COVID-19 may present different and less severe symptoms than adults. However, the epidemiological and clinical patterns in this population group have been unclear. Methods: This is an observational study, with an initial cross-analytical characterization, and with a longitudinal or follow-up component in a group of minors with suspected and or confirmed case of COVID-19, which have outcomes such as improvement, transfer to a higher level of care or death due to respiratory symptoms. The children received medical attention at the Regional General Hospital with Family Medicine No 1 (HGR C / MF No 1), and underwent a Real Time Polymerase Chain Reaction test (RT-PCR). Results: 98 children were studied as suspected cases for COVID-19, who underwent RT-PCR. Of the total 24 were positive and 74 were negatives. The median age was 64.4 months (0 to 203 months), 55 minors were male, 59 children had outpatient management, and of these, 14 had a positive result. Among those who required hospital management (39), 10 children were positive for SARS-CoV-2, 84.7% achieved improvement and were discharged, and four were transferred to a higher level of care hospital. Of the 98 children in the study, 11 died, seven had a negative result and four a positive result for SARS-CoV-2. Conclusions: The main symptoms of the pediatric population in this study were fever, cough and general discomfort. Four of those who died had a positive result for SARS-CoV-2, however, they had other comorbidities.

Abstract Introduction: Metastatic kidney cancer continues to be a therapeutic challenge for urologies and oncologies. With the new systemic therapies, the indication for initial cytoreductive nephrectomy is becoming increasingly controversial. The treatment of the primary tumor at a stage with systemic involvement continues to be a controversial issue. Materials and Methods: By conducting a survey of Latin American hospitals, this publication aims to evaluate the indication for cytoreductive nephrectomy, the preferred surgical technique and the results obtained, estimating regional therapeutic lines. Online survey was made, based on the most important topics of discussion on cytoreductive nephrectomy and metastatic kidney cancer. Results: A total of 20 centers participated on the survey, al of them affirmatively about the realization of cytoreductive nephrectomy. Most of them also offer systemic treatment. Regarding the surgical technique used, most used minimally invasive techniques. Discussion: The international evidence about the role of cytoreductive nephrectomy in this context is varied and subject to permanent change. Individualized treatment, multidisciplinary team are fundamental for the approach of these patients. Conclusions: The subgroup of patients with metastatic kidney cancer is conceptually heterogeneous. Cytoreductive nephrectomy continues to play an important role, sometimes leading role, in the management of selected patients.

Resumen Introducción: El cáncer de riñón metastásico continúa siendo al momento actual un desafío terapéutico para la uro-oncología. Con el advenimiento de las nuevas terapias sistémicas, se vuelve cada vez más discutida la indicación de la nefrectomía citorreductora de inicio, siendo aún controversial el tratamiento quirúrgico sobre el tumor primario en un estadio con compromiso sistémico. Materiales y Métodos: Mediante la realización de una encuesta a centros hospitalarios en Latinoamérica, esta publicación pretende evaluar la indicación de la nefrectomía citorreductora, la técnica quirúrgica empleada y resultados obtenidos, estimando la predicción de líneas terapéuticas regionales. El equipo de investigación diseño una encuesta en formato cuestionario online, basado en los principales puntos de discusión según la bibliografía internacional sobre la nefrectomía citorreductora y el cáncer renal metastásico. Resultados: Un total de 20 centros respondieron de forma completa la pesquisa, afirmativamente con respecto a la realización de nefrectomía citorreductora. La mayoría ofrecen además tratamiento sistémico. En cuanto a la técnica quirúrgica empleada, la mayoría utilizaban técnicas mínimamente invasivas. Discusión: La evidencia internacional con respecto al rol de la nefrectomía citoreductora en este contexto es variada y sujeta a permanente cambio. El tratamiento individualizado y en marco de equipo multidisciplinario fundamental para el abordaje de estos pacientes. Conclusiones: El subgrupo de pacientes con cáncer de riñón metastásicos es conceptualmente heterogéneo. La nefrectomía citoreductora sigue jugando un rol importante, a veces protagónico en el manejo de algunos pacientes seleccionados.

Abstract Objectives: research what is the actual role of the laparoscopic approach in the treatment of benign prostatic hyperplasia, in daily practice of Latin American urologists. Materials and methods: an online survey was conducted during the period June - September 202, send to all members of the Confederación Americana de Urología, through its official networks. Results: laparoscopic adenomectomy is not the preferred approach for the treatment of prostates larger than 100g (4% vs 76% for open adenomectomy), most respondents never performed this technique (76%), however, urologists recognize that the laparoscopic approach has benefits over the open approach (64%). Conclusions: although the laparoscopic approach has shown clear benefits in terms of surgical morbidity compared to the open approach, for most Latin American urologists, the technique has not yet been implemented in routine daily practice, being an unknown technique for most of respondents.

Resumen Objetivos: Conocer cuál es el rol del abordaje laparoscópico en el tratamiento de la hiperplasia prostática benigna (HPB) en la actualidad, en la práctica diaria de los urólogos latinoamericanos. Materiales y métodos: Se diseñó un método de encuesta online que se difundió durante el periodo de junio-setiembre del 2021 a todos los miembros de la Confederación Americana de Urología, mediante las redes sociales de la misma. Resultados: La adenomectomía laparoscópica no es el tratamiento de preferencia para el abordaje de adenomas mayores a 100 gr, la gran mayoría de los encuestados nunca realizó esta técnica (76%), no obstante, la gran mayoría de los urólogos reconoce que el abordaje laparoscópico tiene beneficios sobre el abordaje abierto (64%). Conclusiones: Pese a que el abordaje laparoscópico ha demostrado claros beneficios en cuanto a morbilidad quirúrgica frente al abordaje abierto, reconocido por la gran mayoría de los urólogos latinoamericanos, aún no se ha logrado implementar la técnica en la práctica diaria habitual, siendo una técnica desconocida para la gran mayoría de los encuestados.

Resumo O objetivo deste artigo é avaliar o consumo de alimentos ultraprocessados (AUP) e fatores associados no primeiro ano de vida. Trata-se da análise de dados do seguimento de um ano da coorte de nascimentos MINA-Brasil. Foram coletados dados socioeconômicos, demográficos e obstétricos na maternidade e no seguimento de um ano (n = 774), investigando consumo alimentar do dia anterior à entrevista, a fim de avaliar o consumo de AUP. A razão de prevalência (RP) e o intervalo de confianças (IC 95%) para consumo ≥ 3 AUP foram estimados em modelo de regressão múltiplo de Poisson com variância robusta. A prevalência de consumo ≥ 1 AUP foi 87,5%; e ≥ 3 AUP de 40,5%, estando associado a: menor escolaridade materna (≤ 9 anos [RP: 1,97 IC 95% 1,38; 2,80] e entre 10-12 anos [RP: 1,58, IC 95% 1,13; 2,20) comparados com > 12 anos de escolaridade, índice de riqueza abaixo da média (RP: 1,26, IC 95% 1,04; 1,53) e ter mãe adolescente (RP: 1,28, IC 95% 1,06; 1,55). A ausência de diversidade da dieta foi inversamente associada ao desfecho (RP: 0,65, IC 95% 0,51; 0,81). O consumo ≥ 3 AUP se associou às características maternas de menores escolaridade, índice de riqueza e idade materna, e a diversidade da dieta ao maior consumo de AUP.

Abstract This article aims to assess the consumption of ultra-processed foods (UPFs) during the first year of life and associated factors. We analyzed data from the one-year follow-up of the MINA-Brazil birth cohort. Socioeconomic, demographic and obstetric data were collected in the baseline study and at one-year follow-up (n = 774). Dietary intake during the previous day was assessed using a food frequency questionnaire to determine UPF consumption. Multiple Poisson regression with robust variance was performed to estimate prevalence ratios (PR) and confidence intervals (95%CI) for factors associated with the consumption of ≥ 3 UPFs. Prevalence of UPF consumption and consumption of ≥ 3 UPFs was 87.5% and 40.5%, respectively. Consumption of ≥ 3 UPFs was associated with lower maternal education (≤ 9 years of schooling [PR: 2.02 95%CI 1.42; 2.87] and between 10-12 years of schooling [PR: 1.55, 95%CI 1, 11; 2.14]), below-average wealth index (PR: 1.26, 95%CI 1.04; 1.53), and having a teenage mother (PR:1.19, 95%CI 1.00; 1.49). Lack of dietary diversity was inversely associated with the outcome (RP: 0,65, IC95% 0,51; 0,81). The consumption of ≥ 3 UPFs was associated with lower wealth index, education and maternal age. Dietary diversity was associated with higher levels of UPF consumption.
