Resumo Objetivou-se realizar uma análise espacial da taxa de mortalidade hospitalar (TMH) por síndrome respiratória aguda grave (SRAG) atribuída à COVID-19 em crianças e adolescentes no Brasil no período de 2020 a 2021. Utilizou-se o método de cluster para agrupar as unidades federativas (UFs) com base na TMH. Em 2020, clusters com altas TMHs foram formados por UFs Norte/Nordeste. Em 2021, houve redução na TMH. Os clusters com maiores taxas permaneceram na região N/NE. Diferenças regionais foram observadas nas TMHs. Os achados podem refletir as desigualdades sociais e o acesso à atenção hospitalar, principalmente na faixa etária de menores de 1 ano pela gravidade da doença neste grupo.

Abstract The objective was to perform a spatial analysis of the hospital mortality rate (HMR) due to severe acute respiratory syndrome (SARS) attributed to COVID-19 among children and adolescents in Brazil from 2020 to 2021. A cluster method was used to group federal units (FUs) based on HMR. In 2020, clusters with high HMRs were formed by north/northeast FUs. In 2021, there was a reduction in HMR. Clusters with higher rates remained in the N/NE region. Regional differences were observed in the HMR. The findings may reflect social inequalities and access to hospital care, especially in the under 1-year-old age group due to the severity of the disease in this group.

Abstract The present study evaluated the influence of carvacrol, terpinene-4-ol, and chlorhexidine on the physical-chemical properties of titanium surfaces, cell viability, proliferation, adhesion, and spreading of fibroblasts and osteoblasts in vitro. Titanium surfaces (Ti) were treated with Carvacrol (Cvc), Terpinen-4-ol (T4ol), Chlorhexidine (CHX), DMSO, and ultrapure water (Control group). Physical-chemical modifications were evaluated by surface wettability, the surface free energy (SFE) calculated from the contact angle values using the Owens-Wendt-Rabel-Kaeble (OWRK) equation, scanning electron microscopy (SEM) and energy dispersive spectrometry probe (EDS) system. Cells were seeded onto Ti-treated surfaces and incubated for 24 h and 72 h, then evaluated by Alamar blue assay and fluorescence microscopy. Surfaces treated with Cvc and T4ol showed the presence of Na, O, and Cl. All surfaces showed hydrophilic characteristics and SFE values between 5.5 mN/m and 3.4 mN/m. On the other hand, EDS peaks demonstrated the presence of O and Cl after CHX treatment. A reduction of cell viability and adhesion was noted on titanium surfaces treated with CHX after 24 and 72h. In conclusion, the results indicate that the decontamination with Cvc and T4ol on Ti surfaces does not alter the surface proprieties and allows an adequate interaction with cells involved in the re-osseointegration process such as fibroblasts and osteoblasts.

Resumo O presente estudo avaliou a influência do carvacrol, terpineno-4-ol e clorexidina nas propriedades físico-químicas de superfícies de titânio, viabilidade celular, proliferação, adesão e esplhamento de fibroblastos e osteoblastos in vitro. Superfícies de titânio (Ti) foram tratadas com Carvacrol (Cvc), Terpinen-4-ol (T4ol), Clorexidina (CHX), DMSO e água ultrapura (Grupo Controle). As modificações físico-químicas foram avaliadas pela molhabilidade da superfície, a energia livre de superfície (ELS) calculada a partir dos valores do ângulo de contato usando a equação de Owens-Wendt-Rabel-Kaeble (OWRK), microscopia eletrônica de varredura (MEV) e espectroscopia de raios X por energia dispersiva (EDS). As células foram semeadas em superfícies tratadas com Ti e incubadas por 24 h e 72 h, e avaliadas pelo ensaio Alamar blue e microscopia de fluorescência. As superfícies tratadas com Cvc e T4ol mostraram a presença de Na, O e Cl. Todas as superfícies apresentaram características hidrofílicas e valores de ELS entre 5,5 mN/m e 3,4 mN/m. Por outro lado, os picos de EDS demonstraram a presença de O e Cl após o tratamento com CHX. Uma redução da viabilidade celular e adesão foi observada em superfícies de titânio tratadas com CHX após 24 e 72h. Em conclusão, os resultados indicam que a descontaminação com Cvc e T4ol em superfícies de Ti não altera as propriedades da superfície e permite uma interação adequada com células envolvidas no processo de reosseointegração como fibroblastos e osteoblastos.

Abstract The aim of the present study was to identify how the transition of care from the hospital to the community occurs from the perspective of puerperal women at risk. An integrative literature review was performed, with the question: “How does the transition of care for at-risk puerperal women from the hospital to the community occur?” The search period ranged from 2013 to 2020, in the following databases: PubMed, LILACS, SciELO, and Scopus. MESH, DeCS and Boolean operators “OR” and “AND” are used in the following crossover analysis:patient transfer ORtransition care ORcontinuity of patient care ORpatient discharge ANDpostpartum period, resulting in 6 articles. The findings denote discontinuity of care, given the frequency of non-adherence to the puerperal consultation. Transition studies of care in the puerperium were not found, which requires proposing new studies.

Resumo O objetivo do presente estudo foi identificar como ocorre a transição do cuidado do hospital para a comunidade na perspectiva de puérperas de risco. Foi realizada uma revisão integrativa da literatura, com a questão: “Como ocorre a transição do cuidado das puérperas de risco do hospital para a comunidade?” A pesquisa foi realizada com recorte temporal de 2013 a 2020, nas bases de dados: PubMed, LILACS, SciELO e Scopus. Utilizou-se MESH, DECS e operadores booleanos “OR” e “AND” resultando nos seguintes cruzamentos:patient transfer ORtransition care ORcontinuity of patient care ORpatient discharge ANDpostpartum period, com análise final de 6 artigos. Os achados denotam descontinuidade do cuidado, visto a frequência de não adesão à consulta puerperal. Estudos de transição do cuidado no puerpério não foram encontrados, o que requer que novos estudos sejam propostos.

Abstract Instruments to evaluate psychosocial determinants of fruit and vegetable (F&V) consumption among adolescents are scarce, and there appears to be only one instrument - unnamed and unvalidated - that investigates determinants derived from theories of social psychology targeting the frequency of F&V consumption among adolescents. The scope of this paper was to present the process of cultural adaptation and factor validation of this instrument al-lowing its use in studies with Brazilian adolescents. The cross-cultural adaptation process was accomplished and the final version - named Psychosocial Influence Scale for Fruit and Vegetable Consumption among Adolescents (PSI-FAVES) - was tested with 429 students (58% female) using McDonald’s omega (ω) reliability and Confirmatory Factor Analysis (CFA) as analytical methods. The final version required refinement and the instrument showed adequate overall reliability (ω=0.86) and good fit of the data to the previously elaborated model (CFI=0.955; TLI=0.951 and RMSEA (90%CI) =0.043 (0.038-0.049)), being the first systematically validated instrument to investigate psychosocial determinants of F&V consumption among adolescents.

Resumo Instrumentos para avaliar determinantes psicossociais da ingestão de frutas, verduras e legumes (FLV) de adolescentes são escassos, e há um instrumento - sem nome e validação - que investiga estes determinantes oriundos de teorias da psicologia social e direcionado à frequência de ingestão semanal de FLV de adolescentes. O objetivo foi apresentar o processo de adaptação e validação fatorial deste instrumento para ser aplicado em estudos na população brasileira. Realizou-se equivalência conceitual e de itens; equivalência semântica por tradutores e especialistas e semântica e operacional por entrevistas dirigidas com público-alvo. A versão final - denominada Escala de Influências Psicossociais da ingestão de Frutas, Verduras e Legumes de Adolescentes (PSI-FAVES) - foi testada com 429 estudantes (58% mulheres) utilizando confiabilidade por ômega de McDonald (ω) e Análise Fatorial Confirmatória (AFC) como métodos analíticos. A versão final demandou refinamento e o instrumento apresentou confiabilidade total adequada (ω=0,86) e bom ajuste dos dados ao modelo previamente conjecturado (CFI=0,955; TLI=0,951 e RMSEA (90%IC)=0,043 (0,038-0,049), sendo o primeiro instrumento sistematicamente validado para investigar determinantes psicossociais da ingestão de FLV de adolescentes.

RESUMO Objetivo: Descrever as características clínicas dos casos de Síndrome Respiratória Aguda Grave (SRAG) por COVID-19 em recém-nascidos (RNs) em 2020 e 2021, no Brasil, registrados no Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe). Métodos: As variáveis analisadas foram: sexo, raça/cor, hospitalização, internação em unidade de terapia intensiva (UTI), uso de suporte ventilatório, sinais e sintomas (febre, tosse, saturação de O2<95%, dispneia, desconforto respiratório, diarreia e vômitos), evolução (óbito ou cura), fatores de risco/comorbidades. As variáveis categóricas foram apresentadas em frequências absolutas e relativas. Resultados: Houve 1.649 registros de SRAG por COVID-19 em RNs, com predomínio de pardos nos dois anos. Os sintomas mais frequentes foram, respectivamente, em 2020 e 2021: desconforto respiratório (67,0 e 69,7%), febre (46,3 e 46,2%) e tosse (37,0 e 46,3%). Em 2020, 30,5% dos pacientes receberam suporte ventilatório invasivo, e 41,6% em 2021. Além disso, mais de 55% dos casos precisaram de internação em UTI, e acima de 16% morreram. Conclusão: Destaca-se a elevada proporção de casos que precisou de cuidados intensivos e que evoluíram para óbito.

ABSTRACT Objective: To describe the clinical characteristics of cases of COVID-19 severe acute respiratory syndrome (SARS) in Brazilian newborns (NBs) in 2020 and 2021, recorded in the Influenza Epidemiological Surveillance Information System (Sistema de Informação da Vigilância Epidemiológica da Gripe — SIVEP-Gripe). Methods: The variables analyzed were gender, race/skin color, hospitalization, intensive care unit (ICU) admission, use of ventilatory support, signs and symptoms (fever, cough, O2 saturation<95%, dyspnea, respiratory distress, diarrhea, and vomiting), progress (death or cure), risk factors/comorbidities. Categorical variables were expressed as absolute and relative frequencies. Results: We found 1,649 records of COVID-19 SARS in NBs, with a predominance of multiracial babies in both years. The most frequent symptoms in 2020 and 2021 were, respectively: respiratory distress (67.0 and 69.7%), fever (46.3 and 46.2%), and cough (37.0 and 46.3%). In 2020, 30.5% of patients received invasive ventilatory support; in 2021, this number was 41.6%. In addition, more than 55% of cases required ICU admission, and over 16% died. Conclusion: We emphasize the high proportion of cases that required intensive care and progressed to death.

Abstract The Food Truck segment has become a food option with quality and reduced cost. The objective of the present work was to analyze the hygienic-sanitary quality of street foods sold in food trucks and to propose essential operational requirements for the control of hazards associated with this food sector. The cross-sectional descriptive study model was used with the application of a questionnaire to verify the hygienic-sanitary conditions of the food handlers of the trucks in the state of Rio de Janeiro, Brazil, and a checklist to evaluate the structural conditions and compliance with the standards provided for in legislation. Among the handlers, 60% did not wash their hands properly, 62.9% did not have a training course and 18% of the trucks did not have a sink with potable water. Non-conformities were also observed at the points of sale, mainly due to the absence of an exhaust system and protection gutter for lamps. Thus, a proposal of essential operational requirements for food trucks was elaborated. There is a clear need to recognize this segment as an integral part of the commercialization of street food, proposing a specific control, increasing inspection, and use of a training program.

RESUMO Objetivo: Inquérito nacional de cobertura vacinal aos 12 e 24 meses de idade foi realizado para investigar as quedas nas coberturas a partir de 2016. Métodos: Amostra de 37.836 nascidos vivos das coortes de 2017 e 2018 residentes nas capitais, Distrito Federal (DF) e 12 cidades com mais de 100 mil habitantes, acompanhados nos primeiros 24 meses por registros nas cadernetas de vacinação. Setores censitários foram estratificados segundo condições socioeconômicas, e o mesmo número de crianças foi incluído para cada estrato. Calcularem-se coberturas vacinais de cada vacina e coberturas completas aos 12 e 24 meses, doses aplicadas, válidas e oportunas. Fatores familiares, maternos e da criança associados à cobertura foram pesquisados. Os motivos para não vacinar analisados foram: contraindicações médicas, dificuldades de acesso, problemas no funcionamento do programa e hesitação vacinal. Resultados: Os resultados preliminares mostram que menos de 1% das crianças não foram vacinadas, as coberturas pelo esquema completo são menores que 75% em todas as capitais e no DF, as vacinas com mais de uma dose perdem cobertura progressivamente, há diferenças entre os estratos socioeconômicos, favoráveis aos estratos mais altos em algumas cidades e aos estratos mais baixos em outras. Conclusão: Houve realmente redução da cobertura vacinal em todas as capitais e no DF para as crianças nascidas em 2017 e 2018, denotando piora na execução do Programa Nacional de Imunizações durante os anos de 2017 a 2019. O inquérito realizado não mensurou os impactos da pandemia de COVID-19 que podem ter reduzido ainda mais as coberturas vacinais.

ABSTRACT Objective: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. Methods: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. Results: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. Conclusion: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

ABSTRACT Introduction: Surface treatment is an important technique to increase adhesion between implants and bones, improving its mechanical characteristics and consequently the patient’s comfort. Objectives: Ni-Cr alloys were the object of study in this work, with the purpose of analyzing and evaluating the effect of thin films deposition of titanium nitride via plasma, on its surface and comparing with cathodic cage (CC) and hollow cathode (HC) methods, for dental applications. Methods: Eighteen samples were prepared and the experiment was conducted in two steps: the pre-sputtering (1h, 350 °C, gases: Ar and H) and sputtering (4h, 450 °C, gases: Ar, Ni, and H). To characterize and compare the samples with those of reference, the Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Vickers Microhardness and wettability tests were used. Results: The results presented by SEM showed that during the surface treatment using CC, voids were formed, and using HC, the samples showed a more homogenous behavior. In microhardness tests, using a 25gf load, it was possible to observe that the HC method allowed an increase of 87% when compared to the reference and treated samples. Significance: Lastly, it can be concluded that both methods are suitable for Ni-Cr alloy surface treatment, and the HC technique, a method already used by dental professionals, presents better results due to the formation of a thicker film layer.

Abstract Background Dental anesthetic management in implantable cardioverter defibrillator (ICD) recipients with cardiac channelopathies (CCh) can be challenging due to the potential risk of life-threatening arrhythmias and appropriate ICD therapies during procedural time. Objectives The present study assessed the hypothesis that the use of local dental anesthesia with 2% lidocaine with 1:100,000 epinephrine or without a vasoconstrictor can be safe in selected ICD and CCh patients, not resulting in life-threatening events (LTE). Methods Restorative dental treatment under local dental anesthesia was made in two sessions, with a wash-out period of 7 days (cross-over trial), conducting with a 28h - Holter monitoring, and 12-lead electrocardiography, digital sphygmomanometry, and anxiety scale assessments in 3 time periods. Statistical analysis carried out the paired Student’s t test and the Wilcoxon signed-rank test. In all cases, a significance level of 5% was adopted. All patients were in stable condition with no recent events before dental care. Results Twenty-four consecutive procedures were performed in 12 patients (9 women, 3 men) with CCh and ICD: 7 (58.3%) had long QT syndrome (LQTS), 4 (33.3%) Brugada syndrome (BrS), and 1 (8.3%) Catecholaminergic polymorphic ventricular tachycardia (CPVT). Holter analysis showed no increased heart rate (HR) or sustained arrhythmias. Blood pressure (BP), electrocardiographic changes and anxiety measurement showed no statistically significant differences. No LTE occurred during dental treatment, regardless of the type of anesthesia. Conclusion Lidocaine administration, with or without epinephrine, can be safely used in selected CCh-ICD patients without LTE. These preliminary findings need to be confirmed in a larger population with ICD and CCh.

ABSTRACT Vulnerable populations, such as migrants and refugees, have an increased risk of tuberculosis disease, especially in the first years after arrival in the host country. The presence of migrants and refugees in Brazil exponentially grew over the period between 2011 and 2020, and approximately 1.3 million migrants from the Global South were estimated to be residing in Brazil, most of whom from Venezuela and Haiti. Tuberculosis control programs for migrants can be divided into pre- and post-migration screening strategies. Pre-migration screening aims to identify cases of tuberculosis infection (TBI) and can be carried out in the country of origin (pre-entry) or in the destination country (at entry). Pre-migration screening can also detect migrants at an increased risk of developing tuberculosis in the future. High-risk migrants are then followed up in post-migration screening. In Brazil, migrants are considered a priority group for the active search for tuberculosis cases. However, there is no recommendation or plan regarding screening for TBI in migrants and refugees. Ensuring prevention, diagnosis, and treatment for TBI and tuberculosis disease in migrant populations is an important aspect of tuberculosis control and elimination. In this review article, we address epidemiological aspects and access to health care for migrants in Brazil. In addition, the migration medical screening for tuberculosis was reviewed.

RESUMO Populações vulneráveis, como imigrantes e refugiados, apresentam maior risco de tuberculose doença, especialmente nos primeiros anos após a chegada ao país de acolhimento. A presença de imigrantes e refugiados no Brasil cresceu exponencialmente no período entre 2011 e 2020, sendo estimado que aproximadamente 1,3 milhão de imigrantes do Sul Global residiam no Brasil, a maioria proveniente da Venezuela e do Haiti. Os programas de controle da tuberculose para imigrantes podem ser divididos em estratégias de triagem pré- e pós-migração. A triagem pré-migração visa identificar casos de tuberculose infecção (TBI) e pode ser realizada no país de origem (pré-entrada) ou no país de destino (no momento da entrada). A triagem pré-migração também pode detectar imigrantes com maior risco de desenvolver tuberculose no futuro. Os imigrantes de alto risco são então acompanhados na triagem pós-migração. No Brasil, os imigrantes são considerados um grupo prioritário para a busca ativa de casos de tuberculose. No entanto, não há recomendação ou plano sobre triagem para TBI em imigrantes e refugiados. Garantir a prevenção, o diagnóstico e o tratamento da TBI e da tuberculose doença em populações imigrantes é um aspecto importante do controle e eliminação da tuberculose. Neste artigo de revisão, abordamos aspectos epidemiológicos e acesso à saúde para imigrantes no Brasil. Além disso, revisou-se a triagem médica de imigrantes para tuberculose.
