With a birth prevalence of 1 in 1000, neural tube defects (NTD)s contribute considerably to morbidity and healthcare costs. Known genetic and environmental (non-inherited) risk factors for NTDs account for a small portion of risk, suggesting unidentified risk factors. In animal studies, maternal alcohol and pesticide exposures, independently, led to excess neural cell death, resulting in too few cells for neural tube closure. Human studies report no association between alcohol exposure and NTDs, but small to moderate positive associations for pesticide exposure. Such human etiologic studies of NTDs require a large base population, but frequently include only live births. Exclusion of cases by pregnancy outcomes may create ascertainment and response bias, complicating interpretation of findings. Using data from the National Birth Defects Prevention Study (NBDPS) and the Iowa Registry for Congenital and Inherited Disorders (IRCID), the independent effects of maternal periconceptional (1 month prior through 2 months postconception) alcohol and occupational pesticide exposure on the development of NTDs were examined, and differences in Iowa NTD cases were characterized by pregnancy outcome. Maternal reports of alcohol exposure were obtained for 1223 NTD case infants and 6807 control infants. Adjusted odds ratios, estimated using multivariate logistic regression, were near unity for NTDs by any maternal alcohol exposure, binge episode(s), and type(s) of alcohol consumed. Occupational pesticide exposure was assigned by industrial hygienists for mothers of 502 case and 2950 control infants. Adjusted odds ratios for any exposure and cumulative exposure to any pesticide, insecticides only, and insecticides + herbicides + fungicides were near unity for NTDs. Insecticide + herbicide exposure was positively associated with spina bifida. Among the 279 Iowa NTD case infants ascertained by the IRCID, 167 live births and 112 were other pregnancy outcomes (fetal deaths and elective terminations), which increased in proportion over time. Selected infant and maternal characteristics of live births and other pregnancy outcomes were similar. NBDPS eligibility varied significantly by pregnancy outcome, but participation rates did not. NTD case mothers were similar to Iowa NBDPS control mothers. Efforts were made to improve upon prior etiologic studies of these exposures and NTDs, including increased sample size and improved exposure specificity. Some exposure strata (e.g., herbicides only) and outcome strata (e.g., other rare subtypes) were limited by small numbers. All results may have been affected by response and ascertainment bias. Future studies should aim to use similarly detailed exposure classification methods, increase sample size in less prevalent NTD subtypes, and improve ascertainment of fetal deaths.

Este estudo foi realizado na Clínica Obstétrica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, com cento e oitenta e sete gestantes sem comorbidades, para conhecer o perfil nutricional de gestantes que receberam orientação dietética e avaliar o ganho ponderal materno total, o tipo de parto e os resultados perinatais. Foi realizada pesquisa retrospectiva e descritiva, por meio de consulta dos formulários de anamnese alimentar, dos bancos de dados clínicos e prontuários das pacientes. As gestantes foram classificadas de acordo com o IMC prégestacional: 23 (12,2%) eram de baixo peso (IMC < 19,8 kg/m2); 84 (45%), eutróficas (IMC de 19,8 a 26,0 kg/m2); 37 (19,8%), sobrepeso (IMC de 26,1 a 29,0 kg/m2) e 43 (23%), obesas (IMC > 29,0 kg/m2). No consumo energético, não se constatou diferença entre os grupos. A média de porcentagem de carboidratos, proteínas e lipídeos ingerida foi semelhante entre os grupos. Sobre o perfil da ingestão de micronutrientes, a de cálcio, vitamina A e vitamina C foi semelhante entre os grupos; a de ferro foi maior nas gestantes eutróficas quando comparadas às com sobrepeso e com obesidade (p<0,001); a de folatos foi maior nas gestantes eutróficas quando comparadas às obesas (p=0,002); a de fibras foi menor nas gestantes de baixo peso quando comparadas às eutróficas (p=0,042). O ganho de peso excessivo (acima do recomendado) foi significativamente maior (p=0,009) nas gestantes com sobrepeso e obesidade, porém o ganho ponderal materno médio foi significativamente menor nas obesas (p<0,001). Não foi observada diferença entre os grupos quanto à idade gestacional no parto e o tipo de parto. O peso dos recém-nascidos das gestantes de baixo peso apresentou média significativamente menor (p=0,005) que dos demais grupos. As gestantes com sobrepeso apresentaram maior porcentagem de recém-nascidos com mais de 4000g (p=0,037) que os demais grupos. A proporção de recém-nascidos grandes para a idade gestacional foi significativamente maior (p=0,006) nas gestantes com sobrepeso e com obesidade quando comparadas aos demais grupos. Os índices de Apgar não apresentaram diferença significativa entre os grupos. A indicação de cesárea por vício pélvico foi significativamente mais frequente em gestantes com baixo peso (p = 0,006) quando comparadas aos outros grupos / This study was carried out at Clínica Obstétrica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, with one hundred eighty-seven pregnant women without comorbidities. This study aimed to know the nutrition profile of pregnant women who received dietary counseling and to evaluate the maternal total weight gain, type of delivery and perinatal outcome. A retrospective and descriptive research was carried out through consultation of forms of dietary anamnesis, the clinical databases and medical records. The women were classified according to pre-gestational body mass index (BMI): 23 (12.2%) were underweight (BMI < 19.8 kg/m2), 84 (45%) normal weight (BMI 19.8 to 26.0 kg/m2), 37 (19.8%) overweight (BMI 26.1 to 29.0 kg/m2) and 43 (% 23) obese (BMI > 29.0 kg/m2). No difference was observed in energy consumption between the groups. The averages percentage of carbohydrates, protein and lipid intake were similar between groups. Regarding the profile of micronutrient intake, calcium intake, vitamin A and vitamin C was similar between groups; iron intake was higher in normal weight pregnant women compared to overweight and obese (p<0.001); folate intake was higher in normal weight pregnant women compared to obese (p=0.002); fiber intake was lower in underweight pregnant women compared to normal weight (p=0.042). Excessive weight gain (above the recommended) was significantly higher (p=0.009) in pregnant women with overweight and obesity, however the mean of total maternal weight gain was significantly lower in obese women (p<0.001). No difference was observed between the groups regarding gestational age at delivery and mode of delivery. The weight of newborns of underweight pregnant women had a mean significantly lower (p=0.005) compared to other groups. The overweight pregnant women had a higher percentage of newborns with more than 4000g (p=0.037) compared to other groups. The proportion of newborns large for gestational age was significantly higher (p=0.006) in pregnant women with overweight and obesity compared to other groups. The Apgar scores did not differ significantly between groups.

A gestação em mulheres com insuficiência renal crônica em terapia dialítica é evento incomum. Após a década de 90, houve um aumento no número de casos descritos relatando sucesso na gravidez. Durante o período de 1999- 2007 estudamos os resultados obstétricos e perinatais de 30 gestações que ocorreram em 27 pacientes em terapia dialítica, com idade média de 30,4 ± 5,13 anos (variação: 18-42 anos). Todas as pacientes estavam em hemodiálise. Quinze pacientes realizavam terapia dialítica antes da gestação com tempo médio de 2,93 ± 2,05 anos (variação: 1-8 anos) e treze iniciaram a diálise durante a gravidez. A concentração média de uréia foi 105,07±40,72 mg/dL (variação: 21-172 mg/dL); creatinina sérica foi 5,73±2,23 mg/dL (variação: 2,49-10,4 mg/dL). Hipertensão arterial materna ocorreu em 24 pacientes (85,7%), polidrâmnio em 11 casos (39,3%), hipotireoidismo em 6 casos (21,4%), diabetes gestacional em 5 casos (17,8%). Foi necessário o uso de medicações antihipertensivas em 21 pacientes para controle da hipertensão arterial materna e foi prescrito eritropoetina em 25 pacientes para controle da anemia. Ocorreram 18 partos cesarianas, 10 partos normais e dois partos fórcipe. A idade gestacional média ao nascimento foi de 33,8±3,09 semanas (variação: 27-37 semanas) e o peso médio ao nascimento foi 1839,3±647,94 gramas (variação: 530- 3100 gramas). As complicações neonatais observadas no estudo foram: desconforto respiratório 19 casos (63,3%); necessidade de CPAP 12 casos (40%); necessidade de intubação orotraqueal 9 casos (30%); membrana hialina 7 casos (23,3%); displasia broncopulmonar 5 casos (16,7%); sepse 5 casos (16,7%); uso de surfactante pulmonar 4 casos (13,3%); retinopatia da prematuridade 3 casos (10%); enterocolite necrosante 1 caso (3,3%); hemorragia intracraniana 1 caso (3,3%). Ocorreu no estudo um óbito fetal, um óbito neonatal precoce e um óbito neonatal tardio. A taxa de sobrevida hospitalar dos recém-natos foi de 90%, porém morbidade neonatal permanece elevada, principalmente, em decorrência da prematuridade. / Pregnancy in women with end-stage renal disease (ESRD) requiring chronic dialysis is a rare event. After the 90 decade, there was an increased number of cases reporting success in these pregnancies. During the period of 1999 to 2007 we studied the obstetrical and perinatal outcomes of 30 pregnancies in 27 patients on dialysis, with an average age of 30.4 ± 5.13 years (range: 18-42 years). All patients were on hemodialysis. Fifteen patients were on dialysis before pregnancy with mean time of 2.93 ± 2.05 years (range: 1-8 years) and thirteen began dialysis during pregnancy. The mean serum urea was 105.07±40.72 mg/dL (range: 21-172 mg/dL); serum creatinine was 5.73±2.23 mg/dL (range: 2.49-10.4 mg/dL). Maternal hypertension was present in 24 patients (85.7%); polyhydramnios in 11 patients (39.3%); hypotireoidism in 6 patients (21,4%); gestational diabetes in 5 patients (17.8%). The use of antihypertensive drugs was necessary in 21 patients for maternal hypertension control and erythropoietin was prescribed for 25 patients to control anemia. There were 18 cesarean sections, 10 vaginal deliveries and 2 forcipes deliveries. The mean gestational age at delivery was 33.8±3.09 weeks (range: de 27-37 weeks) and the prematurity rate was 70.6% (23 cases). The birthweight at delivery was 1839.3±647.94g (range: 530-3100 g). Neonatal complications observed in the study were: respiratory distress in 19 cases (63,3%); use of CPAP in 12 cases (40%); need of orotracheal intubation in 9 cases (30%); hyaline membrane disease in 7 cases (23.3%); bronchopulmonary dysplasia in 5 cases (16.7%); sepsis in 5 cases (16.7%); use of surfactant in 4 cases (13.3%); retinopathy of prematurity in 3 cases (10%); necrotizing enterocolitis in 1 case (3.3%); intracranial hemorrhage in 1 case (3.3%).15 newborns were small for gestational age and this was correlated with maternal serum urea >100mg/dL (p=0.035). There was one fetal demise and two neonatal deaths. The newborn survival rate was 90%, but the neonatal morbity remains high among this group of patients, mainly, due to prematurity.
