Compared outcomes of very preterm infants born in 2000 and 2005.

AIM: To compare neonatal and 2-year outcomes in very premature infants born 5 years apart. METHODS: Prospective observational study of infants born before 33 weeks' gestation in 2000 or 2005 admitted to a neonatal intensive care unit in France. We collected perinatal data and evaluated motor, cognitive, neurosensory and behavioural outcomes at 2 years of age. RESULTS: We included 170 infants in 2000 and 173 in 2005. The significant differences in neonatal outcomes were decreases in postnatal corticosteroid use and in percentage of infants with head circumference below the 3rd percentile on days 7 (25% vs. 13%) and 30 (30% vs. 17%). At 2 years of age, rates of follow-up were 87% in 2000 and 94% in 2005. The cerebral palsy rate was 6% in both cohorts. The overall rate of motor disabilities diminished from 30% (41/137) to 18% (26/142), and the rate of mild motor disabilities decreased from 24% to 12%. Rates of cognitive, behavioural and neurosensorial impairments were similar. CONCLUSION: Between 2000 and 2005, motor impairments at 2 years of age diminished in very preterm children (but not cerebral palsy rates). We observed a reduced use of postnatal corticosteroids and a decreased percentage of neonates with head circumference below the third percentile.

Overview of meningococcal epidemiology and national immunization programs in children and adolescents in 8 Western European countries.

Background: In Europe, meningococcal (Men) vaccines are available against 5 of the 6 serogroups responsible of nearly all cases of invasive meningococcal disease (IMD). Meningococcal vaccination has been introduced in the national immunization programs (NIPs) for children and adolescents of numerous European countries, but with no consistent strategy across countries. Objectives: To describe IMD epidemiology, NIPs, and vaccination coverage rates (VCRs) in children and adolescents in 8 Western European countries. Methods: Epidemiological data (from 1999 to 2019), NIPs regarding meningococcal vaccination status, and VCRs were collected from the European Centre for Disease Prevention and Control (ECDC) and/or national websites. Results: MenB was the most common serogroup. In Belgium, Spain, France, the Netherlands, the United Kingdom (UK), and Portugal, incidence was greater for MenW than MenC. In 2019, MenB risk was covered in 2 countries (Italy, UK). MenC risk was covered in all countries, via MenC only (countries: N = 3), MenACWY only (N = 2), or MenC (infants/children) and MenACWY (adolescents) (N = 3) vaccination. VCRs were higher in children than adolescents. Conclusion: Our study confirmed the diversity of NIPs, including in neighboring European countries with similar factors like economic resources and epidemiological risk, thus indicating that other factors underlie NIPs. Convergence toward a more common immunization program including MenACWY and MenB vaccination would promote equity and safe travel regarding infectious diseases for young people, and possibly improve the understanding of vaccination by patients and healthcare professionals.

Association of Intraventricular Hemorrhage and Death With Tocolytic Exposure in Preterm Infants.

Importance: No trials to date have demonstrated the benefits of tocolysis on death and/or neonatal morbidity in preterm infants; tocolytics may affect the fetal blood-brain barrier. Objectives: To assess the risks associated with tocolysis in women delivering prematurely as measured by death and/or intraventricular hemorrhage (IVH) in preterm infants and to compare the association of calcium channel blockers (CCBs) nifedipine and nicardipine hydrochloride vs atosiban used for tocolysis with death and/or IVH. Design, Settings, and Participants: The French 2011 EPIPAGE-2 (Enquête Épidémiologique sur les Petits Âges Gestationnels) cohort was limited to mothers admitted for preterm labor without fever, who delivered from 24 to 31 weeks of gestation from April 1 through December 31, 2011. Groups of preterm infants with vs without tocolytic exposure and groups with atosiban vs CCB exposure were compared. Data analysis was performed from June 7, 2014, through September 3, 2017. Exposures: Tocolytics. Main Outcomes and Measures: The primary outcome was a composite of death and/or IVH in preterm infants. Secondary outcomes included death, IVH, and a composite of death and/or grades III to IV IVH. Results: A total of 1127 mothers (mean [SD] age, 25.5 [6.0] years) experienced preterm labor and gave birth to 1343 preterm infants with a male to female ratio of 1.23 and mean (SD) gestational age of 27 (2.5) weeks. Of these, 789 mothers (70.0%) received tocolytics; 314 (39.8%) received only atosiban, and 118 (15.0%) received only a CCB. In the first analysis, the primary outcome (death and/or IVH) was not significantly different in preterm infants with vs without tocolytic exposure (183 of 363 [50.4%] vs 207 of 363 [57.0%]; relative risk [RR], 0.88; 95% CI, 0.77-1.01; P = .07). The secondary outcome (death and/or grades III-IV IVH) was significantly lower in preterm infants with vs without tocolytic exposure (92 of 363 [25.3%] vs 118 of 363 [32.5%]; RR, 0.78; 95% CI, 0.62-0.98; P = .03). Other outcomes did not differ significantly. In the secondary analysis, death and/or IVH was not significantly different in preterm infants with atosiban vs CCB exposure (96 of 214 [44.9%] vs 62 of 121 [51.2%]; RR, 0.88; 95% CI, 0.70-1.10; P = .26), nor was IVH (77 of 197 [39.1%] vs 48 of 106 [45.3%]; RR, 0.86; 95% CI, 0.66-1.13; P = .29). Conclusions and Relevance: In this population-based study, findings suggest that tocolytics were associated with a reduction of death and severe IVH. Other studies are necessary to compare perinatal outcomes after use of atosiban vs CCBs.

Outcome at Two Years of Very Preterm Infants Born after Rupture of Membranes before Viability.

PURPOSE: To compare the respiratory and neurological outcomes at two years of age of preterm children born before 33 weeks of gestation (WG) after early preterm premature rupture of membranes (EPPROM) between 14 and 24 WG with preterm children without EPPROM. DESIGN AND PATIENTS: This single-center case-control retrospective study was conducted at Rouen University Hospital between 1st January 2000 and 31st December 2010. All the cases with EPPROM born from 26WG to 32WG were included. Each newborn was matched by sex, gestational age (GA) and year of birth to two very preterm children, born without EPPROM. At two years of corrected age, motor and cognitive abilities were assessed by routine score based on the Amiel-Tison and Denver developmental scales. RESULTS: Ninety-four cases with EPPROM before 24WG have been included. The 31 children born from 26WG to 32WG were matched with 62 controls. The EPPROM group had poorer clinical evaluation at one year for motor (p = 0.003) and cognitive developmental scores (p = 0.016). Neuromotor rehabilitation was performed more often (p = 0.013). However, there was no difference at 2 years of age. Children born after EPPROM were hospitalized more often for bronchiolitis (p<0.001) during their first 2 years, which correlates with increased incidence of pneumothorax (p = 0.017), pulmonary hypoplasia (p = 0.004) and bronchopulmonary dysplasia (p = 0.005) during neonatal period. CONCLUSION: At two years, despite an increase in severe bronchiolitis and the need for more neuromotor rehabilitation during the first month of the life after discharge, there was no difference in neurological outcomes in the very preterm children of the EPPROM group compared to those born at a similar GA without EPPROM.

Comparison in outcomes at two-years of age of very preterm infants born in 2000, 2005 and 2010.

OBJECTIVE: To investigate alteration in 2-year neurological/behavioral outcomes of very preterm infants born in a French level three neonatal intensive care unit. METHODS: We conducted a prospective, comparative study of very preterm infants born before 33 weeks' gestation at 5-year intervals in 2000, 2005 and 2010 at Rouen University Hospital. Neonatal mortality/morbidities, ante- and neonatal treatments, and at age 2 years motor, cognitive and behavioral data were collected by standardized questionnaires. RESULTS: We included 536 very preterm infants. Follow-up rates at two years old were 78% in 2000, 93% in 2005 and 92% in 2010 respectively. No difference in gestational age, birthweight, neonatal mortality/morbidities was observed except a decrease in low grade subependymal/intraventricular hemorrhages. Care modifications concerned use of antenatal magnesium sulfate, breast-feeding and post-natal corticosteroid therapy. Significant improvement in motor outcome and dramatic decrease in cerebral palsy rates (12% in 2000, 6% in 2005, 1% in 2010, p<0.001) were observed, as were improvements in feeding behavior. Although a non significant difference to better psychosocial behavior was reported, there was no difference in cognitive outcome. CONCLUSIONS: Improvement in neuromotor outcome and behavior was reported. This could be due to multiple modifications in care: including administration of magnesium sulfate to women at risk of preterm birth, increase in breast-feeding, decrease in low grade subependymal/intraventricular hemorrhages, and decrease in post-natal corticosteroid therapy, all of which require further investigation in other studies. Extended follow-up until school age is mandatory for better detection of cognitive, learning and behavioral disorders.
