ABSTRACT

Uruguay acompaña la tendencia mundial al descenso de la natalidad con un descenso de la mortalidad concomitante, siendo la primera causa de mortalidad infantil la prematurez. Enfocados en la prematurez, es de nuestro interés conocer qué ocurre con estos niños luego del alta de la unidad neonatal. Se realizó el estudio de una cohorte de niños entre 4 y 8 años, nacidos con 32 semanas o menos de edad gestacional y/o con pesos al nacer de 1.500 g o menos, asistidos en su período neonatal en la Asociación Médica de San José, a quienes se les realizó el test de Battelle. Se logró identificar las áreas con mayor dificultad en el desarrollo para cada grupo de edad, concluyendo que se pueden realizar planes específicos de acción para promover el desarrollo de estos niños en la edad preescolar y escolar.


Uruguay follows the global declining trend in birth rates along with decreasing mortality, being prematurity the main cause of infant mortality. We studied premature children who had undergone the Battelle Test and had been discharged from the neonatal unit, a cohort of children between 4 and 8 years of age, born at 32 weeks or less of gestational age and/or having a birth weight of 1500g or less, assisted in their neonatal period at the San José Department Medical Center. We could identify the main areas affecting development for each age group, and concluded that specific action plans can be carried out to promote the development of these children at preschool and school age.


O Uruguai acompanha a tendência mundial de declínio das taxas de natalidade com uma concomitante diminuição da mortalidade, sendo a prematuridade a principal causa de mortalidade infantil. Nos focamos na prematuridade e no estudo do que acontece com essas crianças após a alta da unidade neonatal. Realizamos um estudo de uma coorte de crianças entre 4 e 8 anos que tinham sido submetidas ao Teste de Battelle, nascidas com 32 semanas ou menos de idade gestacional e/ou com peso de nascimento igual ou inferior a 1500g, atendidas no período neonatal na Assistência Médica do Departamento de São José no Uruguai. Foi possível identificar as áreas de maior dificuldade de desenvolvimento para cada faixa etária, e concluir que podem se realizar planos de ação específicos para promover o desenvolvimento dessas crianças em idade pré-escolar e escolar.

ABSTRACT

Introducción: La infección congénita por citomegalovirus es causa de pérdida auditiva y alteraciones cognitivas. La infección perinatal por este virus es más frecuente en neonatos< 1500 g y produce menos secuelas neurológicas. Objetivo: Describir la evaluación neurológica en el primer año de vida en niños muy bajo peso al nacer con infección por citomegalovirus. Métodos: Estudio descriptivo y longitudinal en el que se incuyeron 14 neonatos< 1500 g, con diagnóstico de infección congénita o perinatal por citomegalovirus; a los cuales se les realizó evaluación del neurodesarrollo, ultrasonido craneal, potenciales evocados auditivos de tallo cerebral y potenciales visuales a las 40 semanas, a los seis meses y al año de edad gestacional corregida. En la primera evaluación se realizó además, electroencefalograma. Resultados: El 43 por ciento tuvo infección congénita y 57 por ciento infección perinatal. A las 40 semanas se evaluaron completamente 79 % de los casos, a los seis meses 64 por ciento y al año 36 por ciento. No se observaron anormalidades en el ultrasonido craneal, ni en el electroencefalograma. Al año de edad corregida, se detectaron alteraciones ligeras del neurodesarrolo en 33,3 por ciento del total de casos (2/6) y con igual porcentaje en los niños con infección congénita (1/3) y perinatal (1/3). En ningún paciente evaluado se detectó sordera neurosensorial, ni daño del nervio visual. Conclusiones: Las alteraciones del neurodesarrollo encontradas al año de edad corregida pueden estar relacionadas con la prematuridad o la infección por citomegalovirus. El seguimiento a mediano y largo plazo es necesario para detectar otras secuelas neurológicas de debut tardío(AU)


Introduction: Congenital cytomegalovirus infection is a cause of hearing loss and cognitive impairments. Perinatal infection by this virus is more frequent in neonates< 1500 g and produces fewer neurological sequelae. Objective: To describe neurological evaluation in the first year of life in very low birth weight children with cytomegalovirus infection. Methods: A descriptive and longitudinal study involving 14 neonates< 1500 g, with a diagnosis of congenital or perinatal cytomegalovirus infection; to which neurodevelopmental evaluation, cranial ultrasound, auditory brain stem evoked potentials and visual potentials were performed at 40 weeks, six months and one year of corrected gestational age. In the first evaluation, electroencephalogram was also performed. Results: 43 percent had congenital infection and 57 percent perinatal infection. At 40 weeks, 79 percent of cases were fully evaluated, at six months 64 percent and at one year 36 percent. No abnormalities were observed on the cranial ultrasound or electroencephalogram. At one year of corrected age, slight alterations in neurodevelopment were detected in 33.3 percent of all cases (2/6) and with the same percentage in children with congenital (1/3) and perinatal (1/3) infection. In no patient evaluated, sensorineural deafness or visual nerve damage was detected. Conclusions: The neurodevelopmental alterations found at one year of corrected age may be related to prematurity or cytomegalovirus infection. Medium- and long-term follow-up is necessary to detect other late-onset neurological sequelae(AU)

ABSTRACT

The ideal feeding for premature babies has been the source of extensive debate. The aim of this study was to assess the association between type of feeding at discharge and the nutritional status of very low birth weight infants. This was a retrospective cohort of preterm babies with birth weight ≤1500 g, born between January 2006 and December 2013. The infants were divided into 3 groups according to type of feeding at discharge: exclusive breast milk (group 1), mixed feeding (group 2) and exclusive artificial formula (group 3). Frequencies of each group were calculated, as well as mean Z-score differences in weight, length and head circumference. Six hundred and forty-nine newborns were included. The mean weight of groups 1, 2, and 3 was 1338.7, 1104.0, and 1254.7 g, respectively, and their mean gestational age was 31.9, 30, and 31.2 weeks, respectively. The Z-score differences (means±SD) for groups 1, 2, and 3 were: −0.84±0.68, −1.02±0.75, and −0.86±0.71 for weight, −0.21±1.23, −0.52±1.64 and −0.08±1.34 for head circumference, and −1.10±1.18, −1.54±1.37, and −0.97±1.21 for length. A significant difference was observed between groups 2 and 3 in the adjusted Z-score model for length, with no significant differences in anthropometric measurements for the other comparative analyses. Because of its many advantages, breastfeeding should be stimulated within neonatal units since nutritional status was not influenced by the different types of feeding.

ABSTRACT

ABSTRACT Objective: To compare somatic growth, lung function, and level of physical activity in schoolchildren who had been very-low-birth-weight preterm infants (VLBWPIs) or normal-birth-weight full-term infants. Methods: We recruited two groups of schoolchildren between 8 and 11 years of age residing in the study catchment area: those who had been VLBWPIs (birth weight < 1,500 g); and those who had been normal-birth-weight full-term infants (controls, birth weight ≥ 2,500 g). Anthropometric and spirometric data were collected from the schoolchildren, who also completed a questionnaire regarding their physical activity. In addition, data regarding the perinatal and neonatal period were collected from the medical records of the VLBWPIs. Results: Of the 93 schoolchildren screened, 48 and 45 were in the VLBWPI and control groups, respectively. No significant differences were found between the groups regarding anthropometric characteristics, nutritional status, or pulmonary function. No associations were found between perinatal/neonatal variables and lung function parameters in the VLBWPI group. Although the difference was not significant, the level of physical activity was slightly higher in the VLBWPI group than in the control group. Conclusions: Among the schoolchildren evaluated here, neither growth nor lung function appear to have been affected by prematurity birth weight, or level of physical activity.


RESUMO Objetivo: Comparar o crescimento somático, a função pulmonar e o nível de atividade física entre escolares nascidos prematuros com muito baixo peso e escolares nascidos a termo e com peso adequado. Métodos: Foram recrutados escolares com idade de 8 a 11 anos residentes na mesma área de abrangência do estudo: prematuros e com peso < 1.500 g e controles (nascidos a termo e com peso ≥ 2.500 g). Foram obtidas medidas antropométricas e espirométricas e aplicado um questionário sobre a atividade física. Além disso, foram coletadas informações do período perinatal/neonatal dos recém-nascidos com muito baixo peso (RNMBP) de seus prontuários médicos. Resultados: Dos 93 escolares avaliados, 48 crianças no grupo RNMBP e 45 no grupo controle. Não houve diferenças significativas entre os grupos em relação às características antropométricas e nutricionais ou aos parâmetros de função pulmonar. Não foram encontradas associações entre as variáveis perinatais/neonatais e parâmetros da função pulmonar dos escolares no grupo RNMBP. Embora sem diferença significativa em relação aos níveis de atividade física, o grupo RNMBP apresentou uma tendência de ser mais ativo que o grupo controle. Conclusões: Nos escolares aqui estudados o crescimento e a função pulmonar parecem não ser afetados por prematuridade, peso ao nascimento ou nível de atividade física.

ABSTRACT

Abstract Objective: To determine risk factors during neonatal hospital stay and follow-up associated with failure to thrive in the first year of life of very low birth weight newborns. Methods: Study of preterm very low birth weight newborns followed from 2006 to 2013 in a public institutional hospital program. The study included newborns that attended at least one appointment in each of the three periods: Period I, up to 3 months of corrected age (CA); Period II, 4-6 months of CA; and Period III, 7-12 months of CA. The variables were analyzed by logistic regression with XLSTAT 2014 software (Microsoft®, WA, USA). Failure to thrive (Z-score below -2 SD) was classified as a dichotomous dependent variable (0 - failure/1 - success), while the other variables were classified as explanatory variables for the hospitalization periods and for each of the follow-up periods (I, II, and III). Results: Children born adequate for gestational age increased the chance of Z-score for weight at discharge > -2 SD (OR = 10.217; 95% CI: 1.117-93.436). Metabolic bone disease and retinopathy of prematurity in Period I, as well as hospital readmissions in Periods II and III during follow-up increased the chance of Z-score < -2 SD. Conclusion: Failure to thrive is influenced by intrauterine factors and, subsequently, by several morbidities, both in the birth and hospitalization period, as well as in the post-discharge period and thus, such variables should be prioritized in the follow-up.


Resumo Objetivo: Determinar fatores de risco do período de internação neonatal e do seguimento ambulatorial associados à falha de crescimento no primeiro ano de vida de recém-nascidos de muito baixo peso. Métodos: Estudo com crianças nascidas prematuras de muito baixo peso em acompanhamento de 2006 a 2013 em ambulatório de alto risco de um hospital-escola. Incluídas aquelas que fizera pelo menos uma consulta em cada um dos três períodos assim determinados: Período I - até três meses de idade corrigida (IC); Período II - entre quatro e seis meses de IC; e Período III - entre sete e 12 meses de IC. As variáveis foram analisadas por regressão logística com o programa XLStat 2014 (Microsoft®, WA, EUA). A falha de crescimento (escore z abaixo de --2 DP) foi classificada como variável dependente do tipo dicotômica (0 - falha/1 - sucesso) e as demais variáveis foram classificadas como variáveis explicativas para os períodos de internação e para cada um dos períodos de seguimento (I, II e III). Resultados: Nascer adequado para a idade gestacional aumenta a chance de apresentar escore Z do peso na alta hospitalar acima de -2 DP (OR = 10,217; IC95% 1.117-93,436). Doença metabólica óssea e retinopatia da prematuridade durante o Período I e reinternações nos Períodos II e III de seguimento aumentam a chance de escore z abaixo de -2 DP. Conclusão: A falha de crescimento é influenciada por fatores intrauterinos e posteriormente por diversas morbidades, tanto no período da internação como no pós-alta. Tais variáveis estudadas deveriam ter prioridade no seguimento.

ABSTRACT

Abstract Objectives: To assess the effect of maternal breast milk supplementation on the development of exclusively breast-fed very low birth weight preterm infants at 12 months of corrected age. Methods: A randomized clinical trial with 53 infants followed-up after discharge from the neonatal unit until a corrected gestational age of 12 months. Newborns in the intervention group were breastfed exclusively with maternal milk and received 2 g of a multinutrient supplement (Pré-Nan®, Nestlé, Vevey, Switzerland) added to expressed breast milk twice a day until a corrected age of 4–6 months. The control group was exclusively breastfed without supplementation. After monthly follow-up, developmental assessment was performed using the Bayley III Scale. Results: There was no statistically significant difference on the Bayley III Scale between the intervention and control groups in any of the assessed domains: motor, cognitive, and communication. However, scores in the three domains were always higher in the group that received the supplement. There were a similar number of cases of developmental delay in both groups: seven (28%) in the group that received the supplement and nine (33.3%) in the group that was exclusively breastfed. Conclusions: The results failed to show an association between post-discharge multinutrient supplementation and development in the assessed infants.


Resumo Objetivos: Avaliar o efeito da suplementação do aleitamento materno exclusivo com aditivo multicomponente no desenvolvimento de lactentes nascidos pré-termo de muito baixo peso aos 12 meses de idade gestacional corrigida. Método: Ensaio clínico randomizado com 53 lactentes, acompanhados da alta hospitalar na Unidade Neonatal até o 12° mês de idade gestacional corrigida. Aqueles alocados no grupo intervenção permaneciam em aleitamento materno exclusivo e recebiam dois gramas de suplemento multicomponente em pó (Pré-Nan®, Nestlé, Vevey, Suíça), adicionados ao leite ordenhado duas vezes ao dia, por quatro a seis meses de idade gestacional corrigida. O grupo controle permanecia em aleitamento materno exclusivo sem suplementação. Após acompanhamento mensal, foi feita avaliação do desenvolvimento por meio da Escala de Bayley III. Resultados: Na comparação do desenvolvimento pela Escala de Bayley III entre os grupos intervenção e controle, não houve diferença estatística significativa nos domínios estudados: motor, cognitivo e linguagem. Porém, os valores dos escores foram sempre maiores no grupo intervenção do que no grupo controle nos três domínios. O atraso de desenvolvimento se distribuiu de forma similar nos grupos: sete casos (28%) no grupo intervenção e nove (33,3%) no grupo controle. Conclusões: Os resultados não mostraram associação entre suplementação multicomponente pós-alta e desenvolvimento dos lactentes analisados pela Escala de Bayley III.

ABSTRACT

ABSTRACT OBJECTIVE: To analyze the scientific literature on dietary changes in preterm children during the first years of life. DATA SOURCE: The PubMed database was used for article selection. The texts were analyzed according to their objectives, research design, and research group characteristics. The following were selected to comprise the criteria: (1) publications in the period from 1996 to 2014; (2) participation of infants and children from birth to 10 years of age; (3) development of oral motor skills necessary for feeding; (4) development of the feeding process; and (5) feeding difficulties during childhood. SUMMARY OF THE FINDINGS: There were 282 studies identified, of which 17 were used in the review, and five more articles were identified through the reference list of selected articles, totaling 22 references. CONCLUSION: Very low birth weight preterm newborns are more likely to have feeding problems in early postnatal stages and during childhood when compared with full-term infants. Monitoring the feeding of these infants after hospital discharge is strictly recommended in an early intervention program aiming at better development of feeding skills.


RESUMO OBJETIVO: Analisar a literatura científica sobre alterações alimentares em crianças prematuras durante os primeiros anos de vida. FONTE DOS DADOS: A base de dados do Pubmed foi a precursora para a seleção dos artigos. Os textos foram analisados quanto aos seus objetivos, desenhos da pesquisa e características do grupo pesquisa e foram selecionados os seguintes temas para compor os critérios: (1) publicações de 1996 a 2014; (2) participação de bebês e crianças, do nascimento até os 10 anos; (3) desenvolvimento das habilidades motoras orais necessárias para a alimentação; (4) desenvolvimento do processo de alimentação e (5) dificuldades alimentares durante a infância. SÍNTESE DOS DADOS: Foram identificados 282 estudos, 17 foram usados e cinco artigos foram identificados por meio da lista de referência bibliográfica dos artigos selecionados, totalizando 22 referências bibliográficas. CONCLUSÃO: A revisão permitiu concluir que recém-nascidos pré-termo muito baixo peso (RNPTMBP) são mais propensos a apresentar problemas de alimentação nos estágios iniciais pós-natal e durante a infância quando comparados com crianças a termo. O monitoramento da alimentação após a alta hospitalar é estritamente recomendado em um programa de intervenção precoce com vistas ao melhor desenvolvimento das habilidades alimentares.

ABSTRACT

SUMMARY Objective: to assess the nutritional practices in neonatal intensive care units (NICU) associated with growth retardation in premature (preterm) infants. Methods: retrospective study of preterm infants weighing between 500 and 1,499g admitted to NICU. Evolution of growth and parenteral (PN) and enteral (EN) nutrition practices were analyzed. Results: among 184 preterm infants divided into G1 (500 to 990g; n=63) and G2 (1000 to 1499g; n=121), 169 received PN (G1=63, G2=106). Compared with the recommendations, PN was started late, its progress was slow and the maximum glucose, amino acid, lipid and energy supplies were low in both groups. The initial supply of amino acid and lipid and initial and maximum glucose and energy were lower in G1. The onset of EN was early (1-2 days), the time to reach exclusive EN was appropriate (11-15 days) and the use of human milk was possible in a reasonable amount of time (7-13 days). The multivariate analysis showed that respiratory distress syndrome and obtaining a supply of 120 kcal/kg/day too late increased the chance of weight loss greater than 10%. Sepsis, maximum energy supply for PN <60 kcal/kg/day and obtaining a supply of 120 kcal/kg/day too late increased the chance of regaining birth weight after 14 days, while small for gestational age (SGA) at birth reduced this chance. SGA at birth, sepsis and achieving exclusive enteral nutrition after 14 days increased the chance of being SGA at post-conceptual age of term. Conclusion: improving nutritional practices in the NICU can reduce the growth deficit in premature infants of very low birth weight.


RESUMO Objetivo: avaliar as práticas nutricionais em unidade de cuidados intensivos neonatais (UCIN) associadas a déficit de crescimento em recém-nascidos pré-termo (RNPT). Métodos: estudo retrospectivo de RNPT com peso entre 500 e 1.499 g internados em UCIN. Analisaram-se: evolução do crescimento e práticas de nutrição parenteral (NP) e enteral (NE). Resultados: dentre 184 RNPT divididos em G1 (500 a 990 g; n=63) e G2 (1.000 a 1.499 g; n=121), 169 receberam NP (G1=63; G2=106). Comparando-se com as recomendações, a NP foi iniciada tardiamente, sua progressão foi lenta e as ofertas máximas de glicose, aminoácidos, lipídios e energia foram baixas nos dois grupos. A oferta inicial de aminoácido e lipídio e a inicial e máxima de glicose e energia foram menores no G1. O início da NE foi precoce (1 a 2 dias), o tempo para atingir NE exclusiva foi adequado (11 a 15 dias), e o uso de leite humano foi possível por tempo razoável (7 a 13 dias). A análise multivariada mostrou que a síndrome do desconforto respiratório e o alcance tardio da oferta de 120 kcal/kg/dia aumentaram a chance de perda de peso superior a 10%. Sepse, oferta energética máxima por NP < 60 kcal/kg/dia e alcance tardio da oferta de 120 kcal/kg/dia aumentaram a chance de recuperar o peso de nascimento após 14 dias, enquanto a condição de pequeno para idade gestacional (PIG) ao nascimento reduziu essa chance. PIG ao nascimento, sepse e alcance de NE exclusiva após 14 dias aumentaram a chance de ser PIG na idade pós-conceptual de termo. Conclusão: aprimorar as práticas nutricionais em UCIN pode reduzir o déficit de crescimento em prematuros de muito baixo peso ao nascer.

ABSTRACT

OBJECTIVE: to compare the motor coordination, cognitive, and functional development of preterm and term children at the age of 4 years. METHODS: this was a cross-sectional study of 124 four-year-old children, distributed in two different groups, according to gestational age and birth weight, paired by gender, age, and socioeconomic level. All children were evaluated by the Movement Assessment Battery for Children - second edition (MABC-2), the Pediatric Evaluation of Disability Inventory (PEDI), and the Columbia Mental Maturity Scale (CMMS). RESULTS: preterm children had worse performance in all tests, and 29.1% of the preterm and 6.5% of term groups had scores on the MABC-2 indicative of motor coordination disorder (p = 0.002). In the CMMS (p = 0.034), the median of the standardized score for the preterm group was 99.0 (± 13.75) and 103.0 (± 12.25) for the term group; on the PEDI, preterm children showed more limited skill repertoire (p = 0.001) and required more assistance from the caregiver (p = 0.010) than term children. CONCLUSION: this study reinforced the evidence that preterm children from different socioeconomic backgrounds are more likely to have motor, cognitive, and functional development impairment, detectable before school age, than their term peers. .


OBJETIVO: comparar o desenvolvimento da coordenação motora, o desenvolvimento cognitivo e o desempenho funcional de crianças nascidas pré-termo e a termo, aos quatro anos de idade. MÉTODOS: estudo transversal com 124 crianças de quatro anos de idade, distribuídas em dois grupos distintos, de acordo com a idade gestacional e peso ao nascimento, pareadas com relação ao sexo, idade e nível socioeconômico. Todas as crianças foram avaliadas pelos testes Movement Assessment Battery for Children - Second Edition (MABC-2), Inventário de Avaliação Pediátrica de Incapacidade (PEDI) e Escala de Maturidade Mental Colúmbia (EMMC). RESULTADOS: as crianças pré-termo tiveram pior desempenho em todos os testes, sendo que 29,1% das crianças do grupo pré-termo e 6,5% do grupo a termo apresentaram pontuação no MABC-2 indicativa de sinais de transtorno da coordenação motora (p = 0,002). No Columbia (p = 0,034), a mediana do resultado padronizado para o grupo pré-termo foi de 99,0 (±13,75), e do grupo a termo foi 103,0 (±12,25); no PEDI, crianças pré-termo tiveram menor repertório de habilidades (p = 0,001) e necessitaram de maior assistência do cuidador (p = 0,010) do que as crianças a termo. CONCLUSÃO: este estudo reforça as evidências de que crianças pré-termo, de diferentes níveis socioeconômicos, são mais propensas a apresentarem alterações no desenvolvimento motor, cognitivo e funcional, detectáveis antes da idade escolar, que seus pares nascidos a termo. .

ABSTRACT

OBJECTIVE: to evaluate neonatal sepsis as a risk factor for abnormal neuromotor and cognitive development in very low birth weight preterm infants at 12 months of corrected age. METHODS: this was a prospective cohort study that followed the neuromotor and cognitive development of 194 very low birth weight preterm infants discharged from a public neonatal intensive care unit. The Bayley Scale of Infant Development (second edition) at 12 months of corrected age was used. The outcomes were the results of the clinical/neurological evaluation and the scores of the psychomotor development index (PDI) and mental development index (MDI) of the Bayley Scale of Infant Development II. The association between neonatal sepsis and neuromotor development and between neonatal sepsis and cognitive development was verified by logistic regression analysis. RESULTS: mean birth weight was 1,119 g (SD: 247) and mean gestational age was 29 weeks and 6 days (SD: 2). Approximately 44.3%(n = 86) of the infants had neonatal sepsis and 40.7% (n = 79) had abnormal neuromotor development and/or abnormal psychomotor development index (PDI < 85) at 12 months of corrected age. On the mental scale, 76 (39.1%) children presented abnormal cognitive development (MDI < 85). Children with neonatal sepsis were 2.5 times more likely to develop changes in neuromotor development (OR: 2.50; CI: 1.23-5.10). There was no association between neonatal sepsis and cognitive development impairment. CONCLUSION: neonatal sepsis was an independent risk factor for neuromotor development impairment at 12 months of corrected age, but not for mental development impairment. .


OBJETIVO: avaliar a sepse neonatal como fator de risco para alterações no desenvolvimento neuromotor e mental de prematuros de muito baixo peso aos 12 meses de idade corrigida. MÉTODOS: estudo de coorte prospectivo que acompanhou o desenvolvimento neuromotor e mental de 194 prematuros de muito baixo peso oriundos de uma UTI neonatal pública no Rio de Janeiro. Utilizou-se a Escala Bayley de Desenvolvimento Infantil (segunda edição) aos 12 meses de idade corrigida. Os desfechos foram o resultado da avaliação clínica/neurológica e os resultados da área motora da Escala Bayley e os resultados da área mental (cognitiva) da mesma escala. A associação entre sepse e o desenvolvimento neuromotor e entre sepse e o desenvolvimento mental foi verificada através de regressão logística . RESULTADOS: a média do peso ao nascer foi 1119 g (DP 247) e da idade gestacional 29 semanas e 6 dias (DP 2). Cerca de 44,3% (n = 86) das crianças apresentaram sepse neonatal e 40,7% (n = 79) apresentaram alteração neuromotora e/ou no índice do desenvolvimento psicomotor (PDI<85) aos 12 meses de idade corrigida. Na escala mental, 76 (39,1%) crianças apresentaram alteração (MDI < 85). As crianças que apresentaram sepse neonatal tiveram 2,5 vezes mais chances de desenvolver alteração do desenvolvimento neuromotor do que as crianças que não apresentaram sepse (OR: 2,50; IC 1,23-5,10). Porém, não houve associação entre sepse neonatal e alteração cognitiva. CONCLUSÃO: a sepse neonatal foi um fator de risco independente para alteração do de-senvolvimento neuromotor, mas não para alteração do desenvolvimento mental. .

ABSTRACT

OBJECTIVES: To determine the rate of extrauterine growth restriction in very low birth weight infants and to evaluate the influence of perinatal variables, clinical practices, and neonatal morbidities on this outcome. METHODS: A longitudinal study was performed in four neonatal units in the city of Rio de Janeiro. 570 very low birth weight infants were analyzed. The study included perinatal variables, variables related to clinical practices, and incident morbidities in these preterm infants. Extrauterine growth restriction was defined using z-scores for weight or head circumference < -2 for cor-rected age. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) and R software. RESULTS: This study comprised 570 infants, of which 49% were males, and 33% were small for gestational age (SGA). The mean weight and head circumference at birth were 1,113 ± 267 g and 27 ± 2 cm, respectively. The mean z-scores of birth weight and weight at discharge were -0.96± 0.78 and -1.54 ± 0.75, respectively; for head circumference, the mean z-scores at birth and at discharge were -0.63 ± 1.18 and -0.45 ± 0.94, respectively. The rate of extrauterine growth restriction considering the weight was 26% (149/570) and considering the head circumference, 5% (29/570). SGA was the variable with the greatest impact on both growth restriction for weight (PR = 4.33) and for head circumference (PR = 2.11) in adjusted analyses. CONCLUSION: Extrauterine growth restriction was high in the population, especially for SGA newborns and those with neonatal morbidities .


OBJETIVOS: Determinar a frequência da restrição de crescimento extrauterino em recém-nascidos prétermos de muito baixo peso e avaliar o impacto de variáveis perinatais, práticas clínicas e morbidades neonatais nesta morbidade. MATERIAIS E MÉTODOS: Foi realizado um estudo longitudinal em 4 unidades neonatais do Rio de Janeiro. Foram analisados 570 recém-nascidos pré-termos de muito baixo peso. Foram incluídas no estudo variáveis perinatais, variáveis relacionadas às práticas clínicas e morbidades incidentes nestes recém-nascidos. A restrição de crescimento extrauterino foi definida pelos escores z de peso ou perímetro cefálico < -2 para idade corrigida. Na análise estatística foram utilizados o software SPSS e o software R. RESULTADOS: Foram analisados 570 recém-nascidos dos quais 49% eram do sexo masculino e 33% nasceram pequenos para idade gestacional. A média do peso e perímetro cefálico ao nascimento foi respectivamente 1113 ± 267 g e 27 ± 2 cm. As médias de escore z do peso ao nascimento e na alta foram respectivamente, -0,96 ± 0,78 e -1,54 ± 0,75 e as do perímetro cefálico foram -0,63± 1,18 e -0,45 ± 0,94. A frequência de restrição de crescimento extrauterino considerando o peso foi 26% do perímetro cefálico foi de 5%. Nascer pequeno para idade gestacional foi a variável de maior impacto na restrição de crescimento tanto para o peso (RP 4,33) quanto parao perímetro cefálico (RP 2,11) nas analises ajustadas. CONCLUSÃO: A restrição de crescimento extrauterino foi alta na população, especialmente para os recém-nascidos PIG e com morbidades neonatais. .

ABSTRACT

BACKGROUND: Preterm infants require special considerations than term infants to obtain adequate growth. OBJECTIVE: The aim was to evaluate human milk (HM) in low birth weight premature newborn (LBW-PN) and very low birth weight (VLBW-PN) during hospitalization, maternal factors, and the relationship with nutritional parameters. MATERIAL AND METHODS: 87 LBW-PN and 82 VLBW-PN), admitted in a public hospital in Córdoba, Argentina, were included. Anthropometry, food and biochemical parameters, and child and maternal history were registered. HM contribution was calculated. Anthropometric and biochemical values, days of hospitalization and maternal factors by HM intake were analyzed. RESULTS: Only 36,36


of VLBW-PN and 31,02


of their diet with HM. The hemoglobin concentration at discharge was higher in VLBW-PN group with more HM (p=0,01). There was a statistically significant association between HM amount and height at discharge in the PN with less than 20


of their diet with HM. A high prevalence of cesarean delivery was observed, related to lower HM. CONCLUSIONS: HM contributes to hemoglobin stabilization. Cesarean delivery may be associated with lower contribution of HM to newborn infants.

ABSTRACT

O aumento da sobrevida dos recém-nascidos de muito baixo peso elevou a taxa de sepse tardia nas Unidades de Terapia Intensiva Neonatal. Esses recém-nascidos necessitam de longos períodos de internação e são submetidos a diversos tratamentos que os colocam em risco de adquirir infecção. Na sepse tardia, os sintomas ocorrem a partir do quarto dia de vida ─ ou com mais de 72 horas de vida ─ e está relacionada com fatores neonatais, acometendo mais frequentemente recém-nascidos prematuros de baixo peso, que se encontram internados nas Unidades de Terapia Intensiva Neonatal, sendo os agentes responsáveis de origem hospitalar. Este estudo teve o objetivo de caracterizar os recém-nascidos pré-termo com peso inferior a 1.500g identificando a incidência de sepse neonatal tardia. Trata-se de um estudo observacional, descritivo e prospectivo, cuja amostra foi composta por 30 recém-nascidos pré-termo com peso inferior a 1.500g, internados em Unidade de Terapia Intensiva Neonatal de um Hospital de Universitário de Porto Alegre. A coleta de dados foi realizada por meio de um instrumento, registrando-se prospectivamente os dados dos pré-termos do período de 01 de janeiro de 2013 a 31 de dezembro de 2013. O estudo foi aprovado pela Comissão de Ética e Pesquisa da Instituição em que se desenvolveu a pesquisa. Os resultados demonstraram que dentre os 30 neonatos incluídos no estudo, 14 desenvolveram sepse neonatal tardia, representando 47% do total de RNMBP, prevalecendo o S. coagulase negativo em 12 recém nascidos, o que representou 86% de hemocultura positiva com S. coagulase negativo na amostra com sepse neonatal tardia. A maioria dos neonatos nasceu de cesariana (78%), com média de 28 ± 2 semanas de idade gestacional, sendo que 50% dos pré-termos foi classificado como pequeno para idade gestacional...


The increased survival of preterm low birth weight infants, results in ongoing risk of infection on Neonatal intensive care units. Very low birth weight (VLBW) neonates are in need of extra care for longer time in Neonatal intensive care units due to higher risk of infection. Late-onset sepsis’s symptoms can be detected 72 hours after the birth. This type of sepsis is healthcare-associated and is especially more easily acquired by low birth weight preterm infants. Its objective was to evaluate risk factors of late-onset sepsis in 30 preterm newborns who weigh less than 1.500g. This is an observational, prospective and descriptive study which was held in a University hospital’s Neonatal intensive care units. It was used a research tool to prospectively collect preterm neonates’ data from January, 01 2013 to December, 01 2013. The study was approved by the Institution’s Ethics and Research Committee. Results demonstrate that 14 of 30 newborns developed late-onset sepsis, which represents 47% of the Very low birth weight infants. Presence of Coagulasenegative staphylococci prevailed in 12 Very low birth weightneonates, which depicts 86% of positive blood culture for Coagulase-negative staphylococci. The majority of the infants (78%) were born by cesarean section at 28 ± 2 weeks average of gestational age. Half of the newborns (50%) were classified as small for gestational age. Neonates were hospitalized for 62 ± 27 days average. Future studies should continue investigating Very low birth weight newborns in order to develop the research on risk factor associated to late-onset sepsis, which also aims at preventing nosocomial infections in that population.


El aumento de la supervivencia de los recién nacidos con muy bajo peso elevó la taja de sepsis tardía en las Unidades de cuidados intensivos neonatales. Estos recién nacidos necesitan de períodos de internación prolongados y suelen ser sometidos a varios tratamientos que los ponen en riesgo de contraer infecciones. En la sepsis tardía,los síntomas se producen a partir del cuarto día de vida con más de 72 horas de vida y están relacionados con factores neonatales,que acometen más a menudo os niños prematuros de bajo peso al nacer, que son hospitalizados en las Unidades de cuidados intensivos neonatales, siendo los agentes responsables de origen hospitalario.Este estudio tuve el objetivo de caracterizar los recién nacidos prematuros con peso inferior a 1.500g cuanto a los factores de riesgo para la sepsis neonatal tardía. Se trata de un estudio observacional, descriptivo y prospectivo, cuya amuestra fue compuesta por 30 recién nacidos prematuros con peso inferior a 1.500g, hospitalizados en la Unidades de cuidados intensivos neonatales de un Hospital Universitario de la ciudad de Porto Alegre. La captura de dados fue realizada por medio de un instrumento que registraba prospectivamente los dados de los prematuros, el periodo comprendido entre el 01 Enero 2013 hasta 31 de diciembre 2013...

ABSTRACT

Objetivo: describir y evaluar algunos aspectos relacionados con el peso al nacer en una población de niños con fisuras de labio y paladar. Métodos: estudio descriptivo con fase analítica realizado en el Hospital Pediátrico Provincial Hermanos Cordové, de Manzanillo, Cuba. Se incluyeron, luego de ser seleccionados por conveniencia, 92 niños nacidos con fisuras bucales que fueron atendidos en el centro entre los años 1986 y 2010. Se consideraron las variables siguientes: sexo, peso al nacer y tipo de fisura. Mediante medidas descriptivas se establecen asociaciones intervariables. Los aspectos analíticos incluyen el análisis de varianza y la estimación de riesgo (odds ratio) y su intervalo de confianza del 95 por ciento. Resultados: la prevalencia de bajo peso al nacer en estos pacientes (14,1 por ciento) resultó elevada, en comparación con la población general. Hubo una asociación significativa entre el tipo de fisura y el peso al nacer (X²= 12,65). El riesgo de bajo peso al nacer en los pacientes con fisuras labiales asociadas a fisuras palatinas fue significativo (RP= 6,24; IC 95 por ciento: 1,3-30). Conclusiones: los resultados del estudio se corresponden de manera general con los obtenidos por otros autores. Aparentemente hay una asociación entre el nivel de gravedad de las fisuras y el riesgo de bajo peso al nacer


Objective: to describe and to evaluate some aspects of birthweight in a child population with cleft lip and palate. Methods: descriptive study with an analytical phase conducted in Hermanos Cordove in Manzanillo, Cuba. After a convenience selection, 92 children born with oral clefting were included; they had been seen at the center in the period of 1986 through 2010. The following variables were considered: sex, birthweight and type of cleft. Summary measures allowed setting associations among the variables. The analytical aspects covered the variance analysis and the odds ratio together with the confidence interval of 95 percent. Results: the prevalence of low brithweight in these patients (14.1 percent) was high if compared with that of the general population. There was significant association between the type of oral clefting and the birthweight (X²= 12.65). The low birthweight risk in patients with cleft lips associated to cleft palate was significant (RP= 6.24; IC 95 percent: 1.3-30). Conclusions: the results of the study generally are similar to those of other authors. There is apparently association between the level of severity of oral clefting and low birthweight risk

ABSTRACT

Introducción: la leche materna (LM) en el recién nacido prematuro (RNP) se relaciona con mejora en índices inmunológicos, metabólicos y vinculares. Objetivo: evaluar el aporte de LM en RNP de bajo peso (RNP LBW) y muy bajo peso (RNP-VLBW) y su relación con parámetros nutricionales. Metodología: participaron 87 RNP LBW y 82 RNP VLBW admitidos en el Hospital Materno Neonatal Dr. Ramón Carrillo, durante los años 2007-2012. Se registró la antropometría evolutiva, alimentación y parámetros bioquímicos desde el nacimiento al alta, antecedentes del niño y maternos. Se calculó el aporte de LM por registrosel lactario de LM. Se aplicó el Test de Wilcoxon para analizar valores antropométricos y bioquímicos, días de internación y factores maternos según aporte de LM. Se desarrolló un modelo de Regresión Lineal Múltiple para valorar la asociación entre valores antropométricos y bioquímicos y LM. Resultados: el 36,36% de los RNP VLBW y el 31,02% de los RNP LBW cubrió más del 20% de su alimentación con LM. La hemoglobina sérica al alta fue superior en RNP VLBW que recibieron más LM (p<0.05). En ambos grupos, los RNP con menos del 20% de su ilimentación con LM presentaron una asociación estadísticamente significativa entre la cantidad de LM y la talla al alta hospitalaria. En los RNP VLBW la menor edad materna se asoció a parto por cesárea (p=0.0027), mientras que en RNP LBW hubo una asociación positiva entre mayor edad materna y cesárea (p=0.0015). Conclusiones: la cobertura de LM en los RNP VLBW y LBW hospitalizados en estudio es baja en comparación con el aporte de fórmula láctea (FL). Existiría una asociación entre aporte de LM y crecimiento ponderal en RNP VLBW que recibieron más FL. Además, los valores de hemoglobina en RNP VLBW se asocian a un mayor aporte de LM. Por otro lado, la presencia de cesárea podría asociarse a un menor aporte de LM a los RNP.


ABSTRACT: Introduction: breast milk (BM) in premature newborn (PN) is related to improved immunological, metabolic and emotional indexes. Objective: to evaluate BM in the contribution in low birth weight (PN LBW) and very low birth weight (PN VLBW) and the relationship with nutritional parameters. Methods: 87 PN LBW and 82 PN VLBW, admitted in Neonatal Hospital Dr. Ramón Carrillo, between 2007-2012 were included. Anthropometry, food and biochemical parameters, and child and maternal history during hospitalization were registered. BM contribution was calculated from lactary records. Wilcoxon test was applied to analyze anthropometric and biochemical values, days of hospitalization and maternal factors by BM intake. A multiple linear regression was development to assess the association between anthropometric and biochemical values and BM. Results: only 36.36% of PN VLBW and 31.02% of PN LBW had more than 20% of their diet with BM. The hemoglobin concentration at discharge was higher in N VLBW group with more BM (p<0.05). In both groups, there las a statistically significant association between BM amount and height at discharge in the PN with less than 20% of their diet with BM. In PN VLBW, a low maternal age was associated with cesarean delivery (p=0.0027), while in PN LBW a positive association between increased maternal age and cesarean was observed (p=0.0015). Conclusions: coverage of BM in VLBW and LBW hospitalized under study is low compared with the contribution of formula milk (FM). There would be an association between intake of BM and growth in PNI VLBW receiving more FM. In addition, the hemoglobin in PNI VLBW is associated with a greater contribution of LM. Furthermore, the presence of cesarean may be associated with lower BM contribution to PNI.
