The impact of intrauterine growth restriction on respiratory outcomes.

BACKGROUND: Intrauterine growth restriction (IUGR) is caused by fetal growth below what is normal for its genetic potential. Recent studies have shown a distinct association between changes in umbilical artery flow in IUGR subjects and an increased risk of respiratory morbidity and consequently, higher mortality. The aim of this study was to find the impact of IUGR on the respiratory outcomes of premature neonates born with less than 32 weeks gestational age. METHODS: This retrospective cohort study targeted infants born with less than 32 weeks of gestation, admitted at NCIU, between January 2010 and December 2016. Each selected IUGR case was matched according to gestational age and sex with an appropriate birthweight newborn at a 1:2 ratio, within a 12-month period. RESULTS: The study involved 126 neonates, 42 with IUGR, and 84 control subjects. IUGR was not identified as a predictor of Bronchopulmonary Dysplasia (BDP) (OR 4.80, 95% CI: 1.14-20.21, P=0.033). Abnormal umbilical artery flow (OR 4.80, 95% CI: 1.14-20.21, P=0.033) and late onset sepsis (OR 3.31, 95% CI: 1.04-10.56, P=0.044) were significantly associated with BDP. CONCLUSIONS: It is essential to recognize changes in the umbilical artery flow, especially in high-risk pregnancies such as IUGR, since these represent an a priori risk marker for the development of BDP. The individual and combined effect of IUGR, alterations on umbilical artery flow and extreme prematurity has not yet been completely clarified on the impact on lung morbidity, requiring a larger number of studies.

The influence of preeclampsia, advanced maternal age and maternal obesity in neonatal outcomes among women with gestational diabetes / A influência da pré-eclâmpsia, idade materna avançada e obesidade materna em desfechos neonatais entre mulheres com diabetes gestacional

Abstract Objective The present study aims to analyze adverse fetal or neonatal outcomes in women with gestational diabetes, including fetal death, preterm deliveries, birthweight, neonatal morbidity and mortality, as well as the synergic effect of concomitant pregnancy risk factors and poor obstetric outcomes, as advanced maternal age, maternal obesity and pre-eclampsia in their worsening. Methods The present cohort retrospective study included all pregnant women with gestational diabetes, with surveillance and childbirth at the Hospital da Senhora da Oliveira during the years of 2017 and 2018. The data were collected from the medical electronic records registered in health informatic programs Sclinico and Obscare, and statistical simple and multivariate analysis was done using IBM SPSS Statistics. Results The study participants included 301 pregnant women that contributed to 7.36% of the total institution childbirths of the same years, in a total of 300 live births. It was analyzed the influence of pre-eclampsia coexistence in neonatal morbidity (p = 0.004), in the occurrence of newborns of low and very low birthweight (p < 0.01) and in preterm deliveries (p < 0.01). The influence of maternal obesity (p = 0.270; p = 0.992; p = 0.684) and of advanced maternal age in these 3 outcomes was also analyzed (p = 0,806; p = 0.879; p = 0.985).Using a multivariate analysis, the only models with statistic significance to predict the three neonatal outcomes included only pre-eclampsia (p = 0.04; p < 0.01; p < 0.01). Conclusion Only coexistence of pre-eclampsia showed an association with adverse neonatal outcomes (neonatal morbidity, newborns of low and very low birthweight and preterm deliveries) and can be used as a predictor of them in women with gestational diabetes.

Acute kidney injury in preterm neonates with ≤30 weeks of gestational age and its risk factors.

BACKGROUND: Acute kidney injury (AKI), an abrupt decline in kidney function, is a challenging diagnosis among preterm infants due to some specific features of this population. The aim of this study was to determine the risk factors of developing AKI and the predictive factors for its severity in preterm neonates with less than 31 weeks of gestational age. METHODS: All neonates with less than 31 weeks of gestational age, admitted in our NICU between January 2012 and December 2015, were included. Maternal and neonatal records about demographics, placental abnormalities, perinatal and neonatal period and evolution in NICU, as well as electrolytic analysis and serum creatinine and urea values during their hospitalization were retrospectively collected and analyzed. RESULTS: A total of 106 neonates were included. Of those, 24 were diagnosed with AKI, resulting in a prevalence of 22.6%, and 82 were used as controls. Gestational age (OR=0.39; 95% CI=0.2-0.76; P=0.006), congenital malformations (OR=36.93; 95%CI=2.48-550.59; P=0.009), vasoactive drugs (OR=27.06; 95%CI=3.58-204.45; P=0.001), nonsteroidal anti-inflammatory drugs (OR=9.61; 95%CI=1.78-51.73; P=0.008) and sepsis (OR=7.78; 95%CI=1.32-46.04; P=0.024) were found to be independent risk factors. Cardiac surgery was a predictive factor for AKI severity (OR=25; 95%CI=2.09-298.29; P=0.011). The mortality rate in the AKI group was 41.7%. CONCLUSIONS: AKI in preterm neonates is an important feature that contributes to increase the mortality in NICUs. Thus, it is crucial to know its risk factors to establish prompt diagnosis and prevention and, in this way, be able to improve the prognosis.
