Translation and measurement properties of the Portuguese-Brazil version of the Hammersmith Infant Neurological Examination (HINE-Br).

OBJECTIVE: The current study aimed to translate the Hammersmith Infant Neurological Examination (HINE) into Brazilian Portuguese and analyze the reliability of the translated version for a population of Brazilian infants. METHODS: This was a methodological study, approved by the Ethics Committee, carried out between June 2020 and May 2021. HINE is a standardized clinical neurological examination used for the early detection of cerebral palsy. The quantitative section, "neurological examination", contains 26 items scored from 0 to 3 points, divided into five categories: cranial nerve function, posture, movements, muscle tone and reflexes, and reactions. The HINE translation followed four steps: translation, synthesis, back-translation, and evaluation by an expert committee. To verify the reliability of the HINE-Br (Portuguese-Brazil version) two independent examiners evaluated 43 infants, between 3 and 22 months of age. Internal consistency was verified by Cronbach's Alpha coefficient and interrater reliability by the intraclass correlation coefficient (ICC). RESULTS: The translated version was similar to the original version and a few semantic and idiomatic adjustments were necessary. Appropriate internal consistency (Alpha=0.91) was found for the 26 items of the HINE-Br, as well as strong interrater reliability for the total score (ICC2.1=0.95), and also for the five categories (ICC2.1=0.83-0.95). CONCLUSIONS: The HINE-Br presents adequate rates of internal consistency and interrater reliability, and can be used for the evaluation of children at risk for cerebral palsy, between 3 and 24 months of age, by pediatricians and pediatric physical therapists.

RESUMO Objetivo: Traduzir o Hammersmith Infant Neurological Examination (HINE) para o português brasileiro e analisar a confiabilidade da versão traduzida em lactentes brasileiros. Métodos: Estudo metodológico, aprovado por Comitê de Ética, realizado entre junho de 2020 e maio de 2021. O HINE é um exame clínico neurológico padronizado, utilizado para detecção precoce de paralisia cerebral. A seção quantitativa, "exame neurológico", contém 26 itens pontuados de 0 a 3, divididos em 5 categorias: função dos nervos cranianos; postura; movimentos; tônus muscular e reflexos; e reações. A tradução do HINE seguiu quatro etapas: tradução; síntese; retrotradução; e avaliação por um comitê de especialistas. Dois examinadores independentes avaliaram 43 lactentes, entre 3 e 22 meses, utilizando a versão HINE-Br (versão em português brasileiro), para verificar sua confiabilidade. A consistência interna foi verificada pelo coeficiente Alpha de Cronbach e a confiabilidade interexaminadores pelo coeficiente de correlação intraclasse (CCI). Resultados: A versão traduzida foi semelhante à versão original e poucos ajustes semânticos e idiomáticos foram necessários. Encontrou-se consistência interna adequada (Apha=0,91) para os 26 itens do HINE-Br, bem como forte confiabilidade interexaminadores para o escore total (CCI2,1=0,95) e também para as cinco categorias (CCI2,1=0,83-0,95). Conclusões: O HINE-Br apresenta índices adequados de consistência interna e confiabilidade interexaminadores, podendo ser utilizada para avaliação de crianças com risco de apresentar paralisia cerebral, entre 3 e 24 meses de idade, por pediatras e fisioterapeutas infantis.

Placental morphometry in hypertensive disorders of pregnancy and its relationship with birth weight in a Latin American population.

OBJECTIVE: To assess the placental morphometry in pregnancies with hypertensive disorders of pregnancy (HDP) and its relationship with birth weight (BW). STUDY DESIGN: Cohort study of placental morphometry and fetal outcomes of 954 pregnancies at a university hospital in Ribeirão Preto, São Paulo, Brazil, in 2010. HDP categories were: chronic (CH), gestational (GH), preeclampsia (PRE) and pre-eclampsia superimposed on chronic hypertension (CH + PRE). Associations between BW and placental measures (PM) in pregnancies were evaluated by multiple linear regression analyses. MAIN OUTCOME MEASURES (PM): Placental weight (PW, g), largest and smallest diameters (cm), thickness (cm), eccentricity, area (cm2), volume (cm3), BW/PW ratio and PW/BW ratio (efficiency). RESULTS: The frequencies of each HDP categories were 6.5% CH; 7.6% GH; 6.1% PRE, and 2.0% CH + PRE. PW, largest and smallest diameters, area and BW/PW ratio were statistically different between HDP and the normotensive group, with the lowest values for CH + PRE; the remaining measures showed no difference. BW was lower in HDP than in the normotensive group (p = 0.016). BW and PW were highly correlated in the presence of HDP (r = 0.79, p < 0.001). Sixty-seven percent of BW variability was accounted for PM (p < 0.001), and increased to 81% when maternal variables, gestational age and sex were added (p < 0.001). CONCLUSIONS: Hypertensive disorders of pregnancy significantly influence the growth of both the placenta and the fetus. PM explain 67% of BW variability, and CH + PRE was the category with the strongest association to the results.
