Neuroimaging and neurodevelopmental outcome after early fetal growth restriction: NEUROPROJECT-FGR.

BACKGROUND: Adverse neurodevelopmental outcomes and MRI alterations are reported in infants born after fetal growth restriction (FGR). This study evaluates the additional role of FGR over prematurity in determining brain impairment. METHODS: Retrospective observational study comparing 48 FGR and 36 appropriate for gestational age infants born between 26 and 32 weeks' gestation who underwent a cerebral MRI at term equivalent age. Exclusion criteria were twins, congenital anomalies, and findings of overt brain lesions. Main outcomes were total maturation score (TMS) and cerebral areas independently measured by two neuro-radiologists and Griffiths or Bayley scale III scores at median age of 2 years. RESULTS: TMS was not significantly different between the groups. Inner calvarium and parenchyma's areas were significantly smaller in FGR cases. There were no significant differences in the average quotient scores. A positive correlation between parenchyma area and cognitive score was found (r = 0.372, p = 0.0078) and confirmed after adjusting for sex, gestational age, and birth weight (p = 0.0014). Among FGR, the subgroup with umbilical arterial Doppler velocimetry alterations had significantly worse gross motor scores (p = 0.005). CONCLUSIONS: FGR plays additional role over prematurity in determining brain impairment. An early structural dimensional MRI evaluation may identify infants who are at higher risk. IMPACT: Fetal growth-restricted infants showed smaller cerebral parenchymal areas than preterm controls. There is a positive correlation between the parenchyma area and the cognitive score. These results highlight the already known link between structure and function and add importance to the role of a structural dimensional MRI evaluation even in the absence of overt brain lesions.

Maternal age and body mass index at term: Risk factors for requiring an induced labour for a late-term pregnancy.

INTRODUCTION: We investigated the role of body mass index (BMI) and maternal age on the risk of late-term induction, prolonged induction time and caesarean section (CS) after induction. MATERIAL AND METHODS: This is a retrospective, observational study. All women without any fetal or maternal pathological condition, uterine scars or any other indication for an elective caesarean birth and had a singleton foetus in the cephalic position at term were included. RESULTS: A total of 4006 women had a spontaneous onset of labour and 612 were induced for a late-term pregnancy. Labour induction was significantly more common in overweight (Adj Odds Ratio (OR) 1.48 95%CI 1.22-1.78) and obese (Adj OR 1.63 95%CI 1.24-2.14) women. Among induced women, a BMI ≥ 30 was a risk factor for a prolonged induction time in both nulliparous (AdjOR 2.4, 95%CI 1.02-5.67) and multiparous women (AdjOR 4.24, 95%CI 1.02-17.6). A BMI > 25-29.9 was significantly associated with a prolonged induction time only in nulliparous women (AdjOR 1.86 95%CI 1.05-3.30). A CS was more frequent in overweight (AdjOR 1.74, 95% CI 1.052.89) and obese women (AdjOR 2.72, 95%CI 1.42-5.25). Nulliparous women ageed 30-34 years had an induction time longer than women <30 years (OR 2.04 95%CI 1.07-3.91). CONCLUSIONS: The results of this study suggest that a BMI > 25 kg/m2 at term of pregnancy is a risk factor for the induction of labour during a late-term pregnancy, a prolonged induction time and higher caesarean section rate.

Efficacy of sublingual misoprostol for induction of labor at term and post term according to parity and membrane integrity: a prospective observational study.

OBJECTIVE: To evaluate the effectiveness and safety of 25 mcg sublingual misoprostol for induction of Labor at term according to parity and membrane integrity. METHODS: We conducted a prospective observational study on singleton pregnancies undergoing induction of Labor at term. Twenty-five mcg of misoprostol were administered sublingually every 4 h. Main outcomes were vaginal deliveries within 24 h, time-to-vaginal-delivery, hyper-stimulation syndrome, cesarean section rate, arterial pH< 7.0 and NICU admission rate. RESULTS: We studied 508 patients, 375 nulliparous and 133 multiparous women. Sixty-five percent and 78%, respectively, delivered vaginally within 24 h from first administration. Median time-to-vaginal-delivery was significantly shorter in PROM than in women with intact membranes (p < 0.001). Epidural analgesia prolonged time-to-vaginal-delivery among nulliparous women (p < 0.0005). A positive correlation between BMI and time to delivery was observed in both nulliparous and multiparous women (p < 0.05). Cesarean section rate was 22% in nulliparous and 6% in multiparous group. Induction failure was 1.4% and uterine hyper-stimulation 1%. No pH≤ 7.00 was recorded; overall 7 (1.4%) newborns were admitted to NICU. CONCLUSIONS: Sublingually administered misoprostol is an effective and safe method for induction of Labor at term. Parity, status of membranes and BMI significantly affect time to delivery.
