- Estudo da morbilidade no neurodesenvolvimento, em recém-nascidos de muito baixo pesoPublication . Cunha, M; Ferreira, L; Fonseca, F; Novais, R; Cadete, A; Barroso, R; Nunes, S; Carreiro, H; Botelho, T; Machado, MCObjectivo: Avaliar a prevalência das sequelas no neurodesenvolvimento em Recém-nascidos de muito baixo peso. Metodologia: Estudo transversal para determinação da prevalência das sequelas do neurodesenvolvimento, das crianças nascidas de muito baixo peso num hospital de apoio perinatal diferenciado da Grande Lisboa, de 01/06/96 a 01/06/2000. Realizou-se a avaliação do desenvolvimento através das Escalas Schedule of Growing Skills II e de Desenvolvimento Mental de Ruth Griffiths, o seguimento Oftalmológico e ORL e a avaliação social. Considerou-se sequela do neurodesenvolvimento quando o Quoficiente Geral da Griffiths foi ≤ 70, a SGSII dois intervalos de idade abaixo da idade corrigida, existência de défice sensorial ou défice motor. Resultados: de um total de 21605 nados vivos, houve 268 RNMBP, Destes, 107 foram avaliados (44% dos sobreviventes). Dos 161 não avaliados eram 25 falecidos, 16 transferidos e 120 por falta de seguimento. Dos 107 incluídos na amostra, a idade gestacional média foi de 29,1s (+2.6) e o peso de nascimento médio de 1100g (+235), sexo F/M 55/52. Detectou-se défice auditivo em 11 (15.6%) das 70 crianças que realizaram potenciais evocados auditivos e défice visual de duas (2.3%) das 86 avaliadas. A avaliação do desenvolvimento até aos 4 anos, revelou um atraso global do desenvolvimento em 21 (19,6%) das crianças e deficiência motora em 6 (5,6%). Necessitaram de Apoios Educativos 31 crianças, 24 de Fisioterapia no Hospital e 14 foram orientadas para Centros de Reabilitação. Não se encontraram diferenças estatisticamente significativas entre o grupo de crianças com desenvolvimento normal ou alterado, no que se refere à idade gestacional, peso de nascimento, CRIB, NTISS, corticóides pré-natais, tempo de ventilação, presença de HIV ou leucomalácia. Nas crianças com alterações do desenvolvimento, observou-se uma diferença estatisticamente significativa, no que se refere ao sexo, sendo o masculino predominante.
- Factores preditivos da aderência dos pais a um programa de seguimento de crianças nascidas de muito baixo pesoPublication . Marecos, C; Oliveira, A; Figueiredo, H; Cadete, A; Cunha, MIntroduction: Newborn infants of very low birth weight (VLBW) are at high risk of neurodevelopment disorder, justifying the implementation of early intervention programs for these children. Objectives: Evaluate the effects of long-term "Care Programme for Development” (CPD) applied to VLBW infants, analyze parents' compliance to follow-up and identify perinatal variables with influence on neurodevelopment. Methods: Cross sectional and retrospective study on the implementation and adherence to CPD in a level III hospital between 2001 and 2005. Morbidity defined as neurological or sensorial sequels. Out of 323 VLBW newborns, 265 were enrolled for the study (49 died; 9 transferred). Results: CPD was made on 89%. Comparing groups with follow-up (156/59%) and without follow-up (109/41%), there were significant differences in maternal age (28.7 / 26.1, p=0.001) and pregnancy surveillance (89% / 78%, p=0.008). There was significant association of adherence with maternal age (odds ratio 1.059, 95% CI 1.009-1.112, p=0.019); pregnancy surveillance (odds ratio 0.336, 95% CI 0.141-0.802, p=0.014) and early consultation (Odds ratio 6.390, 95% CI 2.685 -15.208, p<0.001). Group with follow-up evaluated at an average age of 3.6 years. Seventy-nine per cent had normal neurodevelopment, 10% development delay or cognitive impairment, 6.4% cerebral palsy and 4% had attention deficit hyperactivity. Visual deficit in 7.8% and hearing impairment in 10% of 156 evaluated children. Regression analysis showed a positive association between the existence of sequels and male gender (odds ratio 0.384, 95% CI 0.169 to 0.869, p=0.022) and peri-intraventricular hemorrhage (odds ratio 2.965, 95% CI 1.104 to 7.963, p=0.031). After discharge, 31% required specific intervention. Discussion and conclusion: Adherence to CPD was higher in older mothers, surveillance of pregnancy, intervention started in NICU and early consultation after discharge. Low birth weight, male gender, IPVH, ventilation time and BPD seem to be variables associated with poor prognosis of neurodevelopment.
- Patent Ductus Arteriosus: Perinatal Risk FactorsPublication . Nizarali, Z; Marques, T; Costa, C; Barroso, R; Cunha, MBackground: Patent Ductus Arteriosus (PDA) is the most common heart disease among the newborn population. Besides prematurity, other factors are believed to play a significant role in this condition. Aims: Identification of perinatal risk factors associated with PDA in premature or Very Low Birth Weight Infants (VLBW). Material and methods: Transversal study including all infants admitted to a Level III Neonatal Intensive Care Unit, from January 2005 to December 2009 and included in the Very Low Birth Weight Portuguese National Database . Clinical and demographic data were analysed using a logistic regression analysis to identify risk factors for PDA. Results: A total of 318 VLBW or less than 32 weeks Gestational Age (GA) infants were enrolled, 53.6% males. Infants presenting PDA (100; 31.4%) had a lower mean BW ( 914,19 versus 1257,44 grams; p<0.001) and a lower mean GA (27.06 versus 29.77 weeks; p<0.0001). Using univariate logistic regression, both lower BW [OR: 0.99; CI (95%): 0.995-0.997] and lower GA [OR: 0.68; CI (95%): 0.61-0.75] were important risk factors for PDA. Other factors increasing the risk of PDA were: lower Apgar scores at one [OR: 0.77; CI (95%): 0.68-0.86] and five minutes [OR:0.73;CI (95%): 0.62-0.86]; need for resuscitation in the delivery room [OR: 13.1;CI(95%):3.11-55.1]; surfactant administration [OR:8.12;CI(95%):4.13-15.95]; higher CRIB score [OR:1.17;CI(95%): 1.11-1.24], and higher SNAPPEII score [OR: 1.03; CI (95%): 1.02-1.04]. The logistic multivariate regression model using all these variables identified BW [OR: 0.997; CI (95%): 0.996- 0.998] and surfactant treatment [OR: 3.99; CI (95%): 1.903-8.386] as the only risk factors contributing with statistical significance. The analysis of the ROC curve showed a predictive positive value of 82%. Discussion: The most important risk factors were the use of surfactant and BW, the latter increasing by 23%, the risk of PDA for fewer 100 grams. Although surfactant treatment leads to improved respiratory outcomes and survival in VLBW infants, it increased the risk of PDA by an almost fourfold.
