A percepção do estudante de medicina sobre a simulação realística em pediatria / The perception of the medical student about realistic simulation in pediatrics

Resumo Introdução: O uso de simulação realística em emergências pediátricas é particularmente valioso, pois permite o treinamento de habilidades técnicas, atitudinais e cognitivas, ajudando a garantir a segurança do paciente. Objetivo: Este estudo tem como objetivo descrever a percepção do aluno sobre o uso da Simulação Realista de Alta Fidelidade nos módulos de emergência pediátrica durante o internato de medicina. Métodos: Estudo observacional, descritivo, com abordagem quantitativa e qualitativa. Um questionário semiestruturado foi aplicado aos estudantes do sexto ano de medicina ao final dos módulos de internato pediátrico, com oito semanas de duração, de agosto a dezembro de 2020. Todos participaram de dois tipos de atividades sobre 14 temas: simulação de alta fidelidade (SRAF) e discussão estruturada de casos clínicos (DCC). Resultados: Dos 33 participantes, 29 responderam ao questionário. A média de idade foi de 24 ± 1,8 anos, sendo 58,6% do sexo feminino. Todos concordaram que a experiência com SRAF contribuiu para um desempenho mais seguro em emergências pediátricas, considerado ótimo por 76% e bom para os demais. A maioria achava que a associação de SRAF e DCC era o método ideal (96%). A análise de conteúdo das respostas sobre a SRAF destacou unidades temáticas em cinco categorias: aprendizagem significativa, contribuição para a formação profissional, habilidades, atitude/comportamento e qualidade da atividade. Conclusões: A reação dos estudantes ao uso da SRAF em emergências pediátricas foi muito positiva, e sua associação com a DCC foi considerada o método de ensino ideal. Conhecer as reações dos alunos ajuda os professores a planejarem suas atividades para melhorar o método de ensino-aprendizagem.

Abstract Introduction: The use of realistic simulation in pediatric emergencies is particularly valuable, as it allows the training of technical, attitudinal, and cognitive skills, helping to ensure patient safety. Objective: This study aims to describe the student's perception of using the High-Fidelity Realistic Simulation in the pediatric emergency modules during the internship. Methods: Observational, descriptive study with a quantitative and qualitative approach. A semi-structured questionnaire was applied to sixth-year medical students at the end of the pediatric internship modules, which lasted eight weeks, from August to December 2020. All of them participated in two types of activities on 14 topics: high-fidelity simulation (HFS) and structured discussion of clinical cases (SDCC). Results: Of the 33 participants, 29 answered the questionnaire. The mean age was 24 ± 1.8 years, and 58.6% were female. All agreed that the experience with HFS contributed to safer performance in pediatric emergencies, considered optimal by 76% and good for the remainder. Most thought the association of HFS and SDCC was the ideal method (96%). The content analysis of the responses on HFS highlighted thematic units in five categories: significant learning, contribution to professional training, skills, attitude/behavior, and quality of the activity. Conclusions: Students' reaction to using HFS in pediatric emergencies was very positive, and its association with SDCC was considered the ideal teaching method. Knowing the students' reactions helps teachers plan their activities to improve the teaching-learning method.

Maternal-fetal and neonatal characteristics associated with Kangaroo-Mother Care Method adherence

Abstract Objective To describe the association of maternal and neonatal characteristics with the adherence status to the in-hospital stages of the Kangaroo-Mother Care Method - KMC (full, partial, and no-adherence). Methods Retrospective cohort study including infants < 2500 g admitted to a reference maternity hospital for the KMC in Rio de Janeiro from January to December 2018. Maternal and neonatal characteristics were distributed according to the adherence status to the KMC in-hospital stages. In the first stage, KMC is performed in Neonatal Intensive Care Unit and Conventional Neonatal Intermediate Care Unit. The second stage is completed in Kangaroo Neonatal Intermediate Care Unit. Multinomial multiple regression was performed with KMC adherence as a three-category dependent variable and maternal and neonatal characteristics as independent variables. Results Of 166 dyads, 102 (61.5%) participated in two stages. Those who did not participate in any stage (n = 52; 31.3%) had a lower level of education, a higher frequency of adverse conditions, and were more often single mothers; mothers who participated only in the first stage (n = 12; 7,2%) had more premature and sick infants. Conditions associated with adherence to the two stages compared to no adherence were: high school education (OR = 2.34; 95% CI = 1.08-5.07), presence of a partner (OR = 3.82; 95% CI = 1.7-8.61), no adverse conditions (OR = 3.54; 95% CI = 1.59-7.89) and no neonatal resuscitation (OR = 2.73; 95% CI = 1.22-6.1). Conclusions The study identified maternal and neonatal conditions associated with adherence status to the KMC. The results suggest opportunities to improve adherence.

Validity of the computerized version of the pediatric triage system CLARIPED for emergency care

Abstract Objective: To evaluate the validity of the computerized version of the pediatric triage system CLARIPED. Methods: Prospective, observational study in a tertiary emergency department (ED) from Jan-2018 to Jan-2019. A convenience sample of patients aged 0-18 years who had computerized triage and outcome variables registered. Construct validity was assessed through the association between urgency levels and patient outcomes. Sensitivity, specificity, positive and negative predictive values (PPVand NPV), undertriage, and overtriage rates were assessed. Results: 19,122 of 38,321 visits were analyzed. The urgency levels were: RED (emergency) 0.02%, ORANGE (high urgency) 3.21%, YELLOW (urgency) 35.69%, GREEN (low urgency) 58.46%, and BLUE (no urgency) 2.62%. The following outcomes increased according to the increase in the level of urgency: hospital admission (0.4%, 0.6%, 3.1%, 11.9% and 25%), stay in the ED observation room (2.8%, 4.7%, 15.9%, 40.4%, 50%), ≥ 2 diagnostic or therapeutic resources (7.8%, 16.5%, 33.7%, 60.6%, 75%), and ED length of stay in minutes (18, 24, 67,120, 260). The odds of using ≥ 2 resources or being hospitalized were significantly greater in the most urgent patients (Red, Orange, and Yellow) compared to the least urgent (Green and Blue): OR 7.88 (95%CI: 5.35-11.6) and OR 2.85 (95%CI: 2.63-3.09), respectively. The sensitivity to identify urgency was 0.82 (95%CI: 0.77-0.85); specificity, 0.62 (95%CI: 0.61-0.6; NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 4.28% and undertriage, 18.41%. Conclusion: The computerized version of CLARIPED is a valid and safe pediatric triage system, with a significant correlation with clinical outcomes, good sensitivity, and low undertriage rate.

Toxic stress, epigenetics and child development

Abstract Objectives: To describe the concept of toxic stress, present the basics of epigenetics and discuss their relationship with child development. Data source: Narrative literature review through a search in the SciELO, Lilacs, Medline databases using the terms Adverse Childhood Experience OR Early Life Stress, Epigenomic OR Epigenetic, Child Development OR Infant Development. Data synthesis: Continuing stress response, known as toxic stress, can occur when a child experiences intense, frequent, and/or prolonged adversity-such as physical or emotional abuse, chronic neglect, for example-without adequate adult support. This toxic stress can have harmful effects on learning, behavior, and health throughout life. Epigenetics, an emerging scientific research area, shows how environmental influences affect gene expressions and explains how early experiences can impact throughout life. Conclusions: Toxic stress causes changes in the human body response systems that can be explained in part by epigenetic changes, which can be temporary or long-lasting. Pediatricians must be aware of these mechanisms and their consequences, seeking to prevent them and thus promote the health, well-being, and quality of life of children, contributing to their full development.

Correlation between quality of life and the clinical results of patients with leprosy with drop foot after tendon transfer / Avaliação de pacientes com hanseníase pós transposição tendínea para pé caído e sua correlação com a qualidade de vida

ABSTRACT Objective: To evaluate the functional results of surgically correcting drop foot in patients with leprosy and compare their SALSA, Social Participation, and AOFAS score. Methods: Overall, 22 patients were subjected to posterior tibial tendon transfer via the subcutaneous route to the foot dorsum with an average follow-up of 56 months (min 12, max 70). In our sample, 15 of the enrolled patients were men and seven, women, aged between 20 and 73 years old who were operated on from January 2014 to December 2017. The Pearson's correlation test (r) was used to measure the correlation among those scales. A p < 0.05 was considered significant between the pre- and pos-operative AOFAS scale scores. Results: Pre-operative average AOFAS score was 59.6 (min 35, max 74) and 77.2 postoperative (min 36, max 97) (p < 0.0001), postoperative Salsa and Social Participation scale, 30.6 and 22.5, respectively. Statistical analysis suggests a strong positive correlation between AOFAS and Salsa scales (r = −0.83) and AOFAS and social participation (r = −0.78). Average dorsiflexion was 5.4 degrees. Conclusion: The surgical correction of drop foot positively affects the quality of life and social participation of patients with leprosy. Level of Evidence III, Retrospective Study.

RESUMO Objetivo: Avaliar o resultado funcional da cirurgia de correção de pé caído em pacientes hansênicos e comparar as escalas Screening of Activity Limitation and Safety Awareness (SALSA) e de Participação social pós-operatórias com o escore da American Orthopaedic Foot and Ankle Society (AOFAS). Métodos: Avaliamos 22 pacientes submetidos à transposição do tibial posterior para o dorso do pé com mínimo de seguimento de 12 e máximo de 131 meses operados entre janeiro de 2013 e dezembro de 2017. Utilizamos o coeficiente de Pearson (r) para medir o grau de correlação entre as escalas funcionais e consideramos o valor de p < 0,05 na análise dos valores pré e pós-operatórios da AOFAS. Resultados: A média da AOFAS foi de 59,6 no pré-op (mín 35, máx 74) e 77,2 no pós-op (mín 36, máx 97) (p < 0,0001) e das escalas SALSA e participação social de 30,6 e 22,5 no pós-operatório. A análise estatística demonstrou correlação positiva forte (r = −0,83) com as escalas SALSA e de participação social (r = −0,78) quando comparadas ao AOFAS. O grau de dorsiflexão atingido foi de 5,4 graus em média. Linha de pesquisa: Evidência clínica e organizacional, modelos assistenciais, educacionais e avaliação de qualidade em APS - Pós-graduação em Clínica Médica da Faculdade de Medicina da UFRJ. Conclusão: A melhora da função através da correção cirúrgica do pé caído possui correlação direta na melhora da qualidade de vida dos pacientes portadores de hanseníase. Nível de Evidência III, Estudo Retrospectivo.

Improvement of 1st-hour bundle compliance and sepsis mortality in pediatrics after the implementation of the surviving sepsis campaign guidelines

Abstract Objectives To study the impact of the implementation of the Pediatric Surviving Sepsis Campaign protocol on early recognition of sepsis, 1 -h treatment bundle and mortality. Methods Retrospective, single-center study, before and after the implementation of the sepsis protocol. Outcomes: sepsis recognition, compliance with the 1 -h bundle (fluid resuscitation, blood culture, antibiotics), time interval to fluid resuscitation and antibiotics administration, and mortality. Patients with febrile neutropenia were excluded. The comparisons between the periods were performed using non-parametric tests and odds ratios or relative risk were calculated. Results We studied 84 patients before and 103 after the protocol implementation. There was an increase in sepsis recognition (OR 21.5 [95% CI: 10.1-45.7]), in the compliance with the 1 -h bundle as a whole (62% x 0%), and with its three components: fluid resuscitation (OR 31.1 [95% CI: 3.9−247.2]), blood culture (OR 15.9 [95% CI: 3.9−65.2]), and antibiotics (OR 35.6 [95% CI: 8.9−143.2]). Significant reduction between sepsis recognition to fluid resuscitation (152min × 12min, p < 0.001) and to antibiotics administration (137min × 30min) also occurred. The risk of death before protocol implementation was four times greater (RR 4.1 [95% CI: 1.2-14.4]), and the absolute death risk reduction was 9%. Conclusion Even if we considered the low precision of some estimates, the lower limits of the Confidence Intervals show that the implementation of the Pediatric Surviving Sepsis Campaign guidelines alongside a qualitive assurance initiative has led to improvements in sepsis recognition, compliance with the 1 -h treatment bundle, reduction in the time interval to fluid resuscitation and antibiotics, and reduction in sepsis mortality.

Point-of-care ultrasound by the pediatrician in the diagnosis and follow-up of community-acquired pneumonia

Abstract Objectives: To review, analyze, and present the available evidence on the usefulness of point-of-care pulmonary ultrasound in the diagnosis and monitoring of community-acquired pneumonia (CAP), aiming to facilitate its potential inclusion into pediatric clinical reference guidelines. Source of data: A non-systematic research was carried out in the MEDLINE (PubMed), LILACS, and SciELO databases, from January 1985 to September 2019. The articles that were considered the most relevant were selected. Synthesis of data: CAP is a relevant cause of morbidity and mortality in pediatrics and its clinical management remains a major challenge. The systematic use of chest X-ray for its diagnosis is controversial because it exposes the child to ionizing radiation and there are interobserver differences in its interpretation. Recently, the use of point-of-care pulmonary ultrasound by the pediatrician has been presented as an alternative for the diagnosis and monitoring of CAP. A great deal of evidence has disclosed its high sensitivity and diagnostic specificity, with the advantages of no ionizing radiation, relatively low cost, immediate results, portability, and the possibility of repetition according to the requirements of disease evolution. Moreover, its use can help rule out possible bacterial etiology and thus prevent inappropriate antibiotic treatments that favor bacterial resistance. Conclusions: Point-of-care ultrasonography represents an opportunity to improve the diagnosis and monitoring of CAP. However, as an operator-dependent technique, training is required for adequate image acquisition, correct interpretation, and integration with clinical data for correct decision-making.

Clinical and laboratory characteristics of sars-cov-2 infection in children and adolescents / Características clínicas e laboratoriais da infecção por sars-cov-2 em crianças e adolescentes

ABSTRACT Objective: To present the current evidence on clinical and laboratory characteristics of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during childhood and adolescence. Data source: This is a narrative review conducted in the databases: Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Latin American and Caribbean Health Sciences Literature in the Virtual Health Library (LILACS/VHL), Scopus, Web of Science, Cochrane Library, portal of the Coordination for the Improvement of Higher Education Personnel (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES), Scientific Electronic Library Online (SciELO), ScienceDirect, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The terms used were SARS-CoV-2, COVID-19, novel coronavirus, child, newborn, and adolescent. Data synthesis: Unlike adults, most children infected by SARS-CoV-2 have mild or asymptomatic clinical presentations. Symptomatic children mainly have low fever and cough, with some associated gastrointestinal symptoms. Severe cases are rare and occur especially in infants under one year of age. Detection of viral particles in feces seems to be more persistent in children and can be used as a tool for diagnosis and control of the quarantine period. Different from adults, children can present distinct inflammatory responses, as has happened in new cases of Kawasaki-like syndrome associated with SARS-CoV-2 infection. Conclusions: Most children have asymptomatic or mild presentations, with a prevalence of fever, cough, and gastrointestinal symptoms. New cases with different systemic inflammatory reactions in children have been reported, with clinical manifestations distinct from those typically found in adults.

RESUMO Objetivo: Apresentar as atuais evidências sobre as características clínicas e laboratoriais da infecção pelo coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2) durante a infância e a adolescência. Fonte de dados: Revisão narrativa realizada nas bases de dados Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Literatura Latino-Americana e do Caribe em Ciências da Saúde na Biblioteca Virtual em Saúde (LILACS/BVS), Scopus, Web of Science, Cochrane Library, portal da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Scientific Electronic Library Online (SciELO), ScienceDirect e Cumulative Index to Nursing and Allied Health Literature (CINAHL), com o uso dos termos SARS-CoV-2, COVID-19 e novo coronavírus e criança, recém-nascido e adolescente. Síntese dos dados: Diferentemente dos adultos, as crianças infectadas pelo SARS-CoV-2 apresentam formas clínicas leves ou assintomáticas na maior parte dos casos. As crianças sintomáticas apresentam predominantemente febre baixa e tosse, com alguns sintomas gastrointestinais associados. Casos graves são a minoria e ocorrem especialmente abaixo de um ano de idade. A detecção de partículas virais em fezes parece ser mais persistente em crianças, podendo servir como ferramenta diagnóstica e de controle do tempo de quarentena. Diferentemente dos adultos, as crianças podem apresentar respostas inflamatórias distintas, como tem ocorrido nos novos casos de síndrome de Kawasaki-like associada à infecção pelo SARS-CoV-2. Conclusões: Crianças, na sua maioria, apresentam quadros assintomáticos ou leves, com predomínio de febre, tosse e sintomas gastrointestinais. Novos relatos de diferentes reações sistêmicas inflamatórias em crianças têm sido notados, com manifestações clínicas distintas daquelas tipicamente observadas em adultos.

Normal Hearing Function in Children Prenatally Exposed to Zika Virus

Abstract Introduction The association between prenatal Zika virus infection and hearing alterations in offspring has been the object of some studies, although few have assessed children without microcephaly. However, a current trend to include prenatal Zika virus exposure in the group of risk indicators for hearing loss is noted. Objective To present a series of 27 children prenatally exposed to the Zika virus submitted to multiple hearing assessments over time. Methods A cohort of children born to symptomatic mothers with laboratorial Zika virus infection confirmation during pregnancy was submitted to an otoacoustic emission test, auditory brainstem response test (automated, neurodiagnostic and frequency-specific), audiometry, and imitanciometry over a period of 36 months since birth. The hearing assessment was performed independently of the presence of microcephaly or other apparent signs of congenital Zika syndrome. Results The hearing tests presented predominantly normal results. Some children had signs of middle ear pathology. The only microcephalic child had normal electrophysiological tests, as well as preserved audiometric thresholds, but presented altered motor responses to sound. Conclusion Prenatal exposure to Zika virus does not always determine hearing impairment. This risk seems to be more associated to the severity of the central nervous system damage. Hearing screening and follow-ups of the affected children are important, as well as further research in this area.

Brazilian cohorts with potential for life-course studies: a scoping review / Coortes no Brasil com potencial para estudos do ciclo vital: uma revisão de escopo

ABSTRACT OBJECTIVE To identify the Brazilian cohorts that started either in the prenatal period or at birth, to describe their characteristics and the explored variables, and to map the cohorts with potential for studies on early determinants on health and the risk of falling ill on later stages of the life cycle. METHODS A scoping review was carried out. The articles were searched in the electronic databases PubMed and Virtual Health Library (VHL). The descriptors used were [((("Child" OR "Child, Preschool" OR "Infant" OR "Infant, Newborn") AND (Cohort Studies" OR "Longitudinal Studies")) AND "Brazil")]. The inclusion criteria were Brazilian cohorts that started the baseline in the prenatal period or at birth and with at least two follow-ups with the participants. In order to meet the concept of LCE, we excluded those cohorts whose follow-ups were restricted to the first year of life, as well as those that did not address biological, behavioral and psychosocial aspects, and cohorts with data collection of a single stage of the life cycle. RESULTS The search step identified 5,010 articles. Eighteen cohorts were selected for descriptive synthesis. The median number of baseline participants was 2,000 individuals and the median age at the last follow-up was 9 years. Sample loss at the last follow-up ranged from 9.2 to 87.5%. Most cohorts monitored two phases of the life cycle (the perinatal period and childhood). The Southern region had the highest number of cohorts. The main variables collected were sociodemographic and environmental aspects of the family, morbidity aspects, nutritional practices and lifestyle. CONCLUSIONS We recommend the continuity of these cohorts, the approach to different social contexts and the performance of follow-ups with participants in different phases of the life cycle for the strengthening and expansion of life course epidemiology analyses in Brazil.

RESUMO OBJETIVO Identificar as coortes brasileiras iniciadas no período pré-natal ou no nascimento, descrever suas características e as variáveis exploradas, além de mapear as coortes com potencial para se estudar os determinantes precoces de saúde e doença e o risco de adoecer em etapas posteriores do ciclo vital. MÉTODOS Realizou-se uma revisão de escopo. A busca dos artigos foi realizada nas bases de dados PubMed e Biblioteca Virtual em Saúde em 16 de junho de 2018. Os descritores utilizados foram [((("Child" OR "Child, Preschool" OR "Infant" OR "Infant, Newborn") AND ("Cohort Studies" OR "Longitudinal Studies")) AND "Brazil")]. Os critérios de inclusão foram coortes brasileiras que iniciaram a linha de base no período pré-natal ou no nascimento e com pelo menos dois acompanhamentos com os participantes. Foram excluídas as coortes cujos acompanhamentos foram restritos ao primeiro ano de vida, as que não abordaram aspectos biológicos, comportamentais e psicossociais e também aquelas com coleta de informações em um único estágio do ciclo vital. RESULTADOS A etapa de busca identificou 5.010 artigos. Foram selecionadas 18 coortes para a síntese descritiva. A mediana do número de participantes na linha de base foi 2.000 indivíduos e a mediana de idade no último acompanhamento foi 9 anos. A perda amostral no último acompanhamento variou de 9,2 a 87,5%. A maioria das coortes realizou acompanhamentos em duas fases do ciclo vital (período perinatal e infância). A região Sul contemplou o maior número de coortes. As principais variáveis coletadas foram sociodemográficas e ambientais da família, aspectos de morbidade, práticas alimentares e estilo de vida dos participantes. CONCLUSÕES Recomenda-se a continuidade dessas coortes, a abordagem de diferentes contextos sociais e a realização de acompanhamentos com os participantes em diferentes fases do ciclo vital para o fortalecimento e ampliação das análises de epidemiologia do ciclo vital no Brasil.

Auditory findings associated with Zika virus infection: an integrative review / Achados auditivos associados à infecção pelo Zika vírus: uma revisão integrativa

Abstract Introduction: Possible associations between Zika virus infection and hearing loss were observed during the epidemic in the Americas. Objective: To describe the auditory alterations, pathogenesis and recommendations for follow-up in individuals with prenatal or acquired Zika virus infection. Methods: Bibliographic research conducted in March/2018-April/2019 at the main available databases. Article selection, data extraction and quality evaluation were carried out by two independent reviewers. Studies containing auditory evaluation of patients with congenital or acquired Zika virus infection; and/or hypotheses or evidences on the pathophysiology of auditory impairment associated with Zika virus; and/or recommendations on screening and follow-up of patients with auditory impairment by Zika virus were included. Results: A total of 27 articles were selected. Sensorineural and transient hearing loss were reported in six adults with acquired Zika virus infection. Of the 962 studied children, 482 had microcephaly and 145 had diagnostic confirmation of Zika virus; 515 of the 624 children with auditory evaluation performed only screening tests with otoacoustic emissions testing and/or automated click-stimuli auditory brainstem response testing. Studies in prenatally exposed children were very heterogeneous and great variations in the frequency of altered otoacoustic emissions and automated click-stimuli auditory brainstem response occurred across the studies. Altered otoacoustic emissions varied from 0% to 75%, while altered automated click-stimuli auditory brainstem response varied from 0% to 29.2%. Sensorineural, retrocochlear or central origin impairment could not be ruled out. One study with infected mice found no microscopic damage to cochlear hair cells. Studies on the pathogenesis of auditory changes in humans are limited to hypotheses and recommendations still include points of controversy. Conclusion: The available data are still insufficient to understand the full spectrum of the involvement of the auditory organs by Zika virus, the pathogenesis of this involvement or even to confirm the causal association between auditory involvement and virus infection. The screening and follow-up recommendations still present points of controversy.

Resumo Introdução: Possíveis associações entre a infecção pelo Zika vírus e perda auditiva foram observadas durante a epidemia nas Américas. Objetivo: Descrever as alterações auditivas, a patogênese e as recomendações de seguimento em indivíduos com infecção por Zika vírus pré-natal ou adquirida. Método: Uma pesquisa bibliográfica foi realizada em março/2018 a abril/2019 nas principais bases de dados disponíveis. A seleção dos artigos, extração de dados e avaliação de qualidade foram realizadas por dois revisores independentes. Estudos com avaliação auditiva de pacientes com infecção por Zika vírus congênita ou adquirida; e/ou hipóteses ou evidências sobre a fisiopatologia do comprometimento auditivo associado ao Zika vírus; e/ou recomendações sobre triagem e seguimento de pacientes com comprometimento auditivo pelo Zika vírus foram incluídos na pesquisa. Resultados: Um total de 27 artigos foram selecionados. Perdas auditivas neurossensorial e transitória foram relatadas em seis adultos com infecção pelo Zika vírus adquirida. Das 962 crianças estudadas, 482 apresentavam microcefalia e 145 tinham confirmação diagnóstica do Zika vírus; 515 das 624 crianças com avaliação auditiva haviam realizado apenas testes de triagem com teste de emissões otoacústicas e/ou teste de potencial evocado auditivo de tronco encefálico automático com estímulo clique. Estudos em crianças expostas no período pré-natal foram muito heterogêneos e grandes variações na frequência de emissões otoacústicas e potencial evocado auditivo de tronco encefálico automático alterados ocorreram ao longo dos estudos; alterações nas emissões otoacústicas variaram de 0% a 75%, enquanto as alterações no potencial evocado auditivo de tronco encefálico automático variaram de 0% a 29,2%. Não foi possível descartar comprometimento neurossensorial, retrococlear ou de origem central. Um estudo com camundongos infectados não encontrou dano microscópico nas células ciliadas da cóclea. Estudos sobre a patogênese das alterações auditivas em humanos estão limitados a hipóteses e recomendações ainda apresentam pontos de controvérsia. Conclusão: Os dados disponíveis ainda são insuficientes para compreender todo o espectro do envolvimento dos órgãos auditivos pelo Zika vírus, a patogênese desse envolvimento ou até mesmo para confirmar a associação causal entre o envolvimento auditivo e a infecção pelo vírus. As recomendações de triagem e seguimento ainda apresentam pontos de controvérsia.

Interaction between vitamin A supplementation and chronic malnutrition on child development / Interação entre suplementação de vitamina A e desnutrição crônica no desenvolvimento infantil

Abstract 200 million pre-school age children are not developing properly. Delays in child development are associated with multiple factors. This study aims to analyze if vitamin A supplementation is associated with improved development and how this effect could be mediated by nutritional status. Population-based study surveyed a representative sample of 8000 households, 1232 children 0-35 months, in the state of Ceará, Brazil. The variables analysed included child developmental status, nutritional determinants and confounding factors. The main effects and interactions were evaluated using Cox regressive models. Vitamin A supplementation showed protective effect to delay in cognitive and motor development modified by interaction with nutritional status. While well-nourished supplemented children presented a 67% lower risk of cognitive delay (adjusted PRR = 0·33 [0·21-0·53]), stunted children had no benefit from supplementation (adjusted PRR = 0·97 [0·39-2·40]). Vitamin A supplementation has a protective effect on child development, but not in stunted children. This suggests that supplementation is effective in promoting child development, especially if associated to a joint effort to improve the nutritional status of children, given the importance of this mediator.

Resumo Duzentos milhões de crianças em idade pré-escolar não estão se desenvolvendo adequadamente. Os atrasos no desenvolvimento estão associados a múltiplos fatores. Este estudo pretende analisar se a suplementação de vitamina A está associada a melhor desenvolvimento e a forma como esse efeito pode ser mediado pelo estado nutricional. Estudo de base populacional com amostra de 8.000 famílias, 1.232 crianças 0-35 meses, no estado do Ceará, Brasil. As variáveis analisadas incluíram desenvolvimento, determinantes nutricionais e fatores de confusão. Os efeitos e as interações foram avaliados utilizando modelos regressivos de Cox. A suplementação de vitamina A foi protetora para atraso no desenvolvimento cognitivo e motor modificado pela interação com o estado nutricional. Crianças suplementadas bem nutridas apresentaram um risco 67% menor de atraso cognitivo (PRR ajustado = 0 33 [0 21-0 53]), já as crianças desnutridas não se beneficiaram (PRR ajustado = 0 97 [0 39-2 40]). A suplementação tem um efeito protetor sobre o desenvolvimento, mas não em crianças desnutridas. Isso sugere que a suplementação é eficaz na promoção do desenvolvimento, especialmente se associada a um esforço para melhorar o estado nutricional infantil, dada a importância desse mediador.

Effects of Zika infection on growth / Repercussões da infecção por Zika sobre o crescimento

Abstract Objectives: To present the currently available evidence of the effects of congenital Zika virus infection on infant growth, to discuss possible intervening factors, and to describe preliminary data on this growth in a cohort of exposed children. Source of data: Non-systematic review in PubMed, BVS, CAPES, Scopus, Web of Science, Cochrane and Google Scholar databases in the last 5 years, using the terms infection/disease by Zika virus and growth/nutrition/nutritional status/infant nutrition and nutritional needs. Additionally, the anthropometric data of the first 2.5 years of a cohort of children exposed to the Zika virus during pregnancy were reviewed. Synthesis of data: Both intrauterine growth restriction and low birth weight were reported in series of cases of children with congenital Zika syndrome. The postnatal growth deficit of these children appears to be directly proportional to the degree of neurological impairment. The etiology is multifactorial, and nutritional and non-nutritional factors are probably involved. The data from the present cohort show that the head circumference evolution depends on this measurement at birth and that weight-height growth has a trend toward lower weight and length in children with congenital microcephaly and normocephalic at birth who develop some neurological abnormality. Conclusions: The few existing data suggest that, in children with congenital Zika, the greater the degree of neurological impairment, the greater the impact on growth, whether or not associated with microcephaly at birth.

Resumo Objetivos: Apresentar as evidências atualmente disponíveis das repercussões da infecção congênita pelo vírus Zika no crescimento infantil, discutir possíveis fatores intervenientes e descrever dados preliminares desse crescimento em uma coorte de crianças expostas. Fonte dos dados: Revisão não sistemática nos portais de banco de dados PubMed, BVS, Capes, Scopus, Web of Science, Cochrane e Google Scholar nos últimos cinco anos, com o uso dos termos infecção/doença pelo vírus Zika e crescimento/nutrição/status nutricional/nutrição infantil e necessidades nutricionais. Além disso, foram revistos os dados antropométricos dos primeiros dois anos e meio de uma coorte de crianças expostas ao vírus Zika durante a gestação. Síntese dos dados: Tanto a restrição do crescimento intrauterino como o baixo peso ao nascer têm sido relatados em séries de casos de crianças com síndrome de Zika congênita. O déficit de crescimento pós-natal dessas crianças parece ser diretamente proporcional ao grau de comprometimento neurológico. A etiologia é multifatorial, com fatores nutricionais e não nutricionais provavelmente envolvidos. Os dados de nossa coorte mostram que a evolução do perímetro cefálico é dependente do valor dessa medida ao nascimento e que o crescimento pondero-estatural apresenta uma tendência de menor peso e comprimento em crianças com microcefalia congênita e normocefálicas ao nascimento, mas com alguma anormalidade neurológica evolutiva. Conclusões: Os poucos dados existentes sugerem que em crianças com Zika congênita, o impacto sobre o crescimento será tanto maior quanto maior for o grau de comprometimento neurológico, associado ou não à microcefalia ao nascimento.

Validade e confiabilidade de um novo sistema de classificação de risco para emergências pediátricas: clariped / Validity and reliability of a new triage system for pediatric emergency care: clariped

RESUMO Objetivo: Avaliar a validade e a confiabilidade de um sistema de classificação de risco para emergências pediátricas (CLARIPED) desenvolvido no Brasil. Métodos: Fase de validade: estudo observacional prospectivo em crianças de 0 a 15anos atendidas consecutivamente no serviço de emergência pediátrica (SEP) de um hospital terciário entre 2 e 18de julho de 2013. Avaliou-se a associação dos níveis de urgência com desfechos clínicos (utilização de recursos, taxa de admissão no SEP, taxa de hospitalização e tempo de permanência no SEP); e comparou-se o desempenho do CLARIPED com um padrão de referência. Fase de confiabilidade interobservadores: uma amostra de conveniência de pacientes atendidos entre abril e julho de 2013 foi submetida a duas classificações de risco consecutivas e independentes, e estimou-se o Kappa ponderado quadrático. Resultados: Em 1.416 atendimentos realizados na fase de validade, a distribuição de níveis de urgência foi: 0,0% vermelho/emergência; 5,9% laranja/muito urgente; 40,5% amarelo/urgente; 50,6% verde/pouco urgente; e 3,0% azul/sem urgência. Ospercentuais de pacientes que usaram dois ou mais recursos diminuíram do nível laranja para o amarelo, verde e azul (81, 49, 22 e 2%, respectivamente, p<0,0001), assim como a taxa de admissão no SEP, o tempo de permanência no SEP e a taxa de admissão hospitalar. Asensibilidade para discriminar pacientes muito urgentes foi de 0,89 (intervalo de confiança de 95%- IC95% 0,78-0,95), e a taxa de subtriagem foi de 7,4%. Aconfiabilidade interobservadores em 191 pacientes classificados por duas enfermeiras foi substancial (kw2=0,75; IC95% 0,74-0,79). Conclusões: O sistema CLARIPED mostrou boa validade e substancial confiabilidade para classificação de risco em um serviço de emergência pediátrica.

ABSTRACT Objective: To assess the validity and reliability of a triage system for pediatric emergency care (CLARIPED) developed in Brazil. Methods: Validity phase: prospective observational study with children aged 0 to 15 years who consecutively visited the pediatric emergency department (ED) of a tertiary hospital from July 2 to 18, 2013. We evaluated the association of urgency levels with clinical outcomes (resource utilization, ED admission rate, hospitalization rate, and ED length of stay); and compared the CLARIPED performance to a reference standard. Inter-rater reliability phase: a convenience sample of patients who visited the pediatric ED between April and July 2013 was consecutively and independently double triaged by two nurses, and the quadratic weighted kappa was estimated. Results: In the validity phase, the distribution of urgency levels in 1,416 visits was the following: 0.0% red (emergency); 5.9% orange (high urgency); 40.5% yellow (urgency); 50.6% green (low urgency); and 3.0% blue (no urgency). The percentage of patients who used two or more resources decreased from the orange level to the yellow, green, and blue levels (81%, 49%, 22%, and 2%, respectively, p<0.0001), as did the ED admission rate, ED length of stay, and hospitalization rate. The sensitivity to identify patients with high urgency level was 0.89 (confidence interval of 95% [95%CI] 0.78-0.95), and the undertriage rate was 7.4%. The inter-rater reliability in 191patients classified by two nurses was substantial (kw2=0.75; 95%CI 0.74-0.79). Conclusions: The CLARIPED system showed good validity and substantial reliability for triage in a pediatric emergency department.

Viral detection profile in children with severe acute respiratory infection

ABSTRACT Objectives: The role of viral co-detection in children with severe acute respiratory infection is not clear. We described the viral detection profile and its association with clinical characteristics in children admitted to the Pediatric Intensive Care Unit (PICU) during the 2009 influenza A(H1N1) pandemic. Method: Longitudinal observational retrospective study, with patients aged 0-18 years, admitted to 11 PICUs in Rio de Janeiro, with suspected H1N1 infection, from June to November, 2009. The results of respiratory samples which were sent to the Laboratory of Fiocruz/RJ and clinical data extracted from specific forms were analyzed. Results: Of 71 samples, 38% tested positive for H1N1 virus. Of the 63 samples tested for other viruses, 58 were positive: influenza H1N1 (43.1% of positive samples), rhinovirus/enterovirus (41.4%), respiratory syncytial vírus (12.1%), human metapneumovirus (12.1%), adenovirus (6.9%), and bocavirus (3.5%). Viral codetection occured in 22.4% of the cases. H1N1-positive patients were of a higher median age, had higher frequency of fever, cough and tachypnea, and decreased leukometry when compared to H1N1-negative patients. There was no difference in relation to severity outcomes (number of organic dysfunctions, use of mechanical ventilation or amines, hospital/PICU length of stay or death). Comparing the groups with mono-detection and co-dection of any virus, no difference was found regarding the association with any clinical variable. Conclusions: Other viruses can be implicated in SARI in children. The role of viral codetection has not yet been completely elucidated.

The Experience of Family Medicine Interns Conducting McGill ILLNESS Narrative Interview with Non-Compliant Chronic Patients / A Experiência de Alunos do Internato em Medicina de Família e Comunidade na Condução de Entrevistas McGill MINI Narrativa de Adoecimento com Pacientes Crônicos com Dificuldades de Adesão ao Tratamento

ABSTRACT Despite several governmental policies with the purpose of changing medical training in Brazil, it is still predominantly hospital-centered, and the learning process is focused on diseases. We conducted a study in a traditional medical school, in which the students carried out an interview focused on the illness experience assessing chronic patients with compliance difficulties in the treatment of hypertension and/or diabetes in primary care. Fourteen medical students during the Family Medicine Internship at the Federal University of Rio de Janeiro were trained to carry out the McGill Illness Narrative Interview (MINI) and identify the modes of understanding and attribution of meaning to the illness and treatment experience. Before and after the completion of the set of 35 interviews, the students were listened to individually regarding their understanding of the compliance phenomenon and the experience with the MINI. The 35 interviews conducted by the students were analyzed with respect to the objectives of each section, in addition to interviewer's general objective of offering a position of expertise to the patient in their report of the case. We sought to investigate the consistency of the student's experience with this script to obtain the narrative of illness using conceptual topics - prototypes and explanatory models - and the emerging topics identified according to the technique described by Bardin for content analysis. In the analysis of the interviews conducted by the researcher with the interns at the beginning and the end of their internship, the content analysis consisted of two main themes: clinical understanding and experience with the non-compliance phenomenon, and the appreciation of performing the MINI in the context of medical training. The students considered the MINI a useful tool for understanding and exploring the individuals' illness and their treatment experiences in their socioeconomic and cultural context. By recognizing the importance of the MINI, the interns usually reported few learning opportunities while providing care for patients. Although the students had previously recognized the importance of listening and the development of bonds, they did not know how these issues could be built, and the experience increased their confidence in the healthcare provided to patients in their medical daily life. The students noticed that non-compliance involved multiple factors, which did not usually emerge during regular medical appointments. In fact, there was more understanding about the compliance phenomenon.

RESUMO A formação médica no Brasil, apesar das várias políticas indutoras governamentais objetivando sua mudança é, ainda, predominantemente hospitalocêntrica, sendo o processo de aprendizagem centrado na doença. Em uma escola médica tradicional, realizamos uma pesquisa na qual o aluno do Internato conduziu uma entrevista voltada para experiência de adoecimento com pacientes crônicos com dificuldades de adesão ao tratamento de hipertensão e/ou diabetes na Atenção Primária. Quatorze Internos em Medicina de Família e Comunidade da Universidade Federal do Rio de Janeiro foram treinados a aplicar a Entrevista McGill MINI Narrativa de Adoecimento para identificar os modos de compreensão e atribuição de sentidos da experiência de adoecimento e tratamento. Antes e depois da realização do conjunto de 35 entrevistas McGill MINI, os alunos foram individualmente ouvidos quanto a sua compreensão do fenômeno adesão e à experiência com a entrevista McGill MINI. As 35 entrevistas realizadas pelos alunos foram analisadas quanto ao alcance dos objetivos de cada seção da entrevista McGill MINI, além do objetivo geral do entrevistador ser capaz de ofertar um lugar de expertise ao paciente no relato de sua experiência de adoecimento. Buscamos investigar a consistência da experiência do aluno com este roteiro para a obtenção da narrativa de adoecimento, utilizando para tal os temas conceituais desta entrevista - protótipos e modelos explicativos - e os temas emergentes identificados através da análise de conteúdo realizada conforme a técnica descrita por Bardin. Na análise das entrevistas realizadas pela pesquisadora com os Internos ao início e final do Internato, a análise temática foi feita a partir de dois grandes temas: compreensão e experiência clínica com o fenômeno da adesão, e apreciação da experiência de realização da entrevista McGill MINI no contexto da formação médica. Os alunos reconheceram a entrevista McGill MINI como útil para compreender e explorar a experiência de adoecimento e tratamento de um indivíduo no seu contexto socioeconômico e cultural. Ao reconhecerem esta importância da entrevista McGill MINI, os Internos frequentemente referiam as poucas oportunidades de aprendizagem na abordagem de pacientes em geral. Apesar de previamente reconhecerem a importância da escuta e do desenvolvimento do vínculo, desconheciam como isto poderia ser construído, e a experiência aumentou a autoconfiança no cuidado às pessoas no cotidiano médico. Os alunos perceberam que a não-adesão envolve múltiplos fatores, que normalmente não aparecem durante uma consulta médica habitual, e houve de fato uma ampliação na compreensão do fenômeno da adesão.

Spontaneous and induced abortion trends and determinants in the Northeast semiarid region of Brazil: a transversal series / Tendência de abortos espontâneos e induzidos na região semiárida do Nordeste do Brasil: uma série transversal

Abstract Objectives: this study intends to estimate the rates, associated factors and trends of selfreported abortion rates in the northeast of Brazil. Methods: series of population-based surveys realized in Ceará, northeast of Brazil, one of the poorest states in the country. A sample of about 27,000 women of reproductive age was used. Abortion was assessed according to women´s information and rates were calculated using official population estimates. The trends and the association among socioeconomic and reproductive factors were studied using regressive models. Results: a trend for reduction in rates was identified. For induced abortion, the determinants were: not having a partner, condom in the last sexual intercourse, first child up to 25years old (AOR= 5.21; ACI: 2.9 - 9.34) and having less than 13years old at first sexual intercourse (AOR= 5.88; ACI: 3.29 - 10.51). For spontaneous abortion were: having studied less than 8 years, knowledge and use of morning-after pill (AOR= 26.44; ACI: 17.9 - 39.05) and not having any children (AOR= 3.43). Conclusions: rates may have been low due to self-reporting. Young age and knowledge about contraceptive methods were associated to both kinds of abortion, while education level along with spontaneous and marital status with induced. Programs to reduce abortion rates should focus on single younger women with low education.

Resumo Objetivos: este estudo objetiva estimar as taxas, fatores associados e tendência das taxas de aborto no Nordeste do Brasil. Métodos: série de estudos transversais realizada no Ceará, um dos estados mais pobres do país. Uma amostra de cerca de 27000 mulheres em idade reprodutiva foi utilizada. A ocorrência de aborto foi aferida através de informação dada pela participante e taxas foram calculadas usando estimativas populacionais oficiais. As tendências e associações entre fatores socioeconômicos e reprodutivos foram estudadas através de modelos regressivos. Resultados: foi identificada tendência de redução nas taxas de abortamento. Para aborto induzido, os determinantes foram não ter um parceiro fixo, ter utilizado camisinha na última relação sexual, ter tido o primeiro filho com menos de 25 anos (AOR= 5,21; ACI: 2,9 - 9,34), e ter tido a primeira relação com menos de 13 anos (AOR= 5,88; ACI: 3,29 - 10,51). Para o espontâneo, ter estudado menos de oito anos, conhecimento sobre a pílula do dia seguinte (AOR= 26,44; ACI: 17,9 - 39,05), e não ter filhos (AOR= 3,43). Conclusões: as taxas podem ser subestimadas por serem auto relatadas. Estar na adolescência e ter conhecimento sobre métodos contraceptivos foram associados aos dois tipos de aborto, enquanto nível educacional com o espontâneo e estado conjugal com induzido. Programas para reduzir taxas de abortamento deveriam focar em mulheres solteiras e com baixa educação.
