    ABSTRACT: The rates of delivery by Cesarean section (CS) have been trending upwards in recent decades, perhaps leading to higher rates of dysfunction in respiratory adaptation in newborns. We present epidemiological data for pulmonary adaptation by mode of delivery for healthy late preterm and term infants born at a regional tertiary care center. The overall CS rate was 22% with the largest proportion of these in late preterms (39%). This drops to 30% in infants born after 37 weeks gestation and to 11% for those born after 40 weeks. Infants needing respiratory support decreased significantly as gestational age increased: 88% at 34 weeks, 67% at 35 weeks, 28% at 36 weeks, 17% at 37 weeks and 8% at 40 weeks. The risk of respiratory morbidity following CS as compared to vaginal delivery (VD) was substantially higher. 50% of infants born by CS needed respiratory support compared to only 12% following VD. 82% of all late preterm infants born by CS developed respiratory morbidity compared to 36% following VD. Comparable data for infants born after 37 and 40 weeks gestation were 33% compared to 9% and 26% compared to 6% respectively. Late preterm infants born after 36 weeks gestation showed the most marked difference by mode of birth with 66% needing respiratory support following CS as compared to only 9% following VD. Our data could be useful in counselling parents about risk associated with delivery by Cesarean section. A critical view should be taken of increasing CS rates worldwide because of a clear correlation in increased morbidity in infants, especially late preterm infants. © Georg Thieme Verlag KG Stuttgart · New York.

    ABSTRACT: Tolerating higher partial pressure of carbon dioxide (pCO2) in mechanically ventilated, extremely low birthweight infants might reduce ventilator-induced lung injury and bronchopulmonary dysplasia. We aimed to test the hypothesis that higher target ranges for pCO2 decrease the rate of bronchopulmonary dysplasia or death. In this randomised multicentre trial, we recruited infants from 16 tertiary care perinatal centres in Germany with birthweight between 400 g and 1000 g and gestational age 23-28 weeks plus 6 days, who needed endotracheal intubation and mechanical ventilation within 24 h of birth. Infants were randomly assigned to either a high target or control group. The high target group aimed at pCO2 values of 55-65 mm Hg on postnatal days 1-3, 60-70 mm Hg on days 4-6, and 65-75 mm Hg on days 7-14, and the control target at pCO2 40-50 mmHg on days 1-3, 45-55 mm Hg on days 4-6, and 50-60 mm Hg on days 7-14. The primary outcome was death or moderate to severe bronchopulmonary dysplasia, defined as need for mechanical pressure support or supplemental oxygen at 36 weeks postmenstrual age. Cranial ultrasonograms were assessed centrally by a masked paediatric radiologist. This trial is registered with the ISRCTN registry, number ISRCTN56143743. Between March 1, 2008, and July 31, 2012, we recruited 362 patients of whom three dropped out, leaving 179 patients in the high target and 180 in the control group. The trial was stopped after an interim analysis (n=359). The rate of bronchopulmonary dysplasia or death in the high target group (65/179 [36%]) did not differ significantly from the control group (54/180 [30%]; p=0·18). Mortality was 25 (14%) in the high target group and 19 (11%; p=0·32) in the control group, grade 3-4 intraventricular haemorrhage was 26 (15%) and 21 (12%; p=0·30), and the rate of severe retinopathy recorded was 20 (11%) and 26 (14%; p=0·36). Targeting a higher pCO2 did not decrease the rate of bronchopulmonary dysplasia or death in ventilated preterm infants. The rates of mortality, intraventricular haemorrhage, and retinopathy did not differ between groups. These results suggest that higher pCO2 targets than in the slightly hypercapnic control group do not confer increased benefits such as lung protection. Deutsche Forschungsgemeinschaft.

    ABSTRACT: Background To determine whether the secretor gene fucosyltransferase (FUT)2 polymorphism G428A is predictive for adverse outcomes in a large cohort of very-low-birth weight (VLBW) infants.Methods We prospectively enrolled 2406 VLBW infants from the population-based multi-center cohort of the German Neonatal network cohort (2009-2011). The secretor genotype (rs601338) was assessed from DNA samples extracted from buccal swabs. Primary study outcomes were clinical sepsis, blood-culture confirmed sepsis, intracerebral hemorrhage (ICH), necrotizing enterocolitis (NEC) or focal intestinal perforation (FIP) requiring surgery and death.ResultsBased on the assumption of a recessive genetic model, AA individuals had a a higher incidence of ICH (AA: 19.0% vs. 14.9 %, p=0.04) which was not significant in the additive genetic model (multivariable logistic regression analysis; A allele carriers: 365 cases, 1685 controls; OR 1.2; 95% CI: 0.99-1.4; p=0.06). Other outcomes were not influenced by FUT2 genotype in either genetic model.Conclusions This large-scale multicenter study did not confirm previously reported associations between FUT2 genotype and adverse outcomes in preterm infants.Pediatric Research (2015); doi:10.1038/pr.2015.1.

    ABSTRACT: To assess the influence of an infusion of clonidine 1 μg/kg/hr on fentanyl and midazolam requirement in ventilated newborns and infants. Prospective, double-blind, randomized controlled multicenter trial. Controlled trials.com/ISRCTN77772144. Twenty-eight level 3 German PICUs/neonatal ICUs. Ventilated newborns and infants: stratum I (1-28 d), stratum II, (29-120 d), and stratum III (121 d to 2 yr). Patients received clonidine 1 μg/kg/hr or placebo on day 4 after intubation. Fentanyl and midazolam were adjusted to achieve a defined level of analgesia and sedation according to Hartwig score. Two hundred nineteen infants were randomized; 212 received study medication, 69.7% were ventilated in the postoperative care and 30.3% for other reasons. Primary endpoint: consumption of fentanyl and midazolam in the 72 hours following the onset of study medication (main observation period) in the overall study population. The confirmatory analysis of the overall population showed no difference in the consumption of fentanyl and midazolam. Explorative age-stratified analysis demonstrated that in stratum I (n = 112) the clonidine group had a significantly lower consumption of fentanyl (clonidine: 2.1 ± 1.8 μg/kg/hr, placebo: 3.2 ± 3.1 μg/kg/hr; p = 0.032) and midazolam (clonidine: 113.0 ± 100.1 μg/kg/hr, placebo: 180.2 ± 204.0 μg/kg/hr; p = 0.030). Strata II (n = 43) and III (n = 46) showed no statistical difference. Sedation and withdrawal-scores were significantly lower in the clonidine group of stratum I (p < 0.001). Frequency of severe adverse events did not differ between groups. Clonidine 1 μg/kg/hr in ventilated newborns reduced fentanyl and midazolam demand with deeper levels of analgesia and sedation without substantial side effects. This was not demonstrated in older infants, possibly due to lower clonidine serum levels.

    ABSTRACT: Background: Nicotine and alcohol consumption have been associated with premature delivery and adverse neonatal outcome. We wanted to analyze the influence of self-reported nicotine and alcohol consumption on outcome of VLBW infants. Material and methods: In an ongoing multicenter study 2475 parents of former very low birth weight (VLBW) infants born between January 2009 and December 2011 answered questionnaires about maternal smoking habits and alcohol consumption during pregnancy. 2463 (99.5%) completed questions on alcohol consumption and 2462 (99.5%) on smoking habits. These infants were stratified to reported maternal smoking and alcohol consumption during pregnancy. We compared the reasons for premature delivery, neonatal outcome and parental reports on bronchitis during the first year of life, as well as growth and development at age 2 years to pregnancy exposure. Results: In nicotine exposed infants intrauterine growth restriction (31 vs. 21%, p<0.01), a birth weight below the 10th percentile (26 vs. 17%, p<0.01) and placenta abruption (9.2 vs. 5.8%, p<0.05) was seen more often. Premature rupture of membranes (24 vs. 30%, p<0.05) or HELLP syndrome (6 vs. 11%, p<0.01) was less frequent. A birth weight below the 3rd percentile was seen more frequently in mothers with reported alcohol consumption (13 vs. 6%, p<0.05). We noted an increased rate of BPD and ROP if mothers reported smoking during pregnancy (p<0.05). Growth parameters and scores on Bayley Sscales of infant development at age 2 years did not differ. Conclusion: Smoking during pregnancy results in a high rate of growth restricted VLBW infants. Prenatal exposition to nicotine seems to increase postnatal complications such as BPD und ROP.

    ABSTRACT: Background and aims Recommendations concerning the assessment of cardiorespiratory events during the first immunization with diphtheria-tetanus-pertussis-inactivated polio-Haemophilus influenzae type B (DTP-IPV-Hib) and Pneumococcal conjugate vaccine (PCV) of extremely preterm infants are discussed controversely. We examined the relationship between the immunization and cardiorespiratory events in preterm infants by using a mobile event monitor. Methods We enrolled 84 extremely preterm infants [39 girls, 45 boys; gestational age (GA) < 28.0 weeks (range 23.5–27.6)]. Immunization took place in the last week before discharge (mean GA: 38 weeks). Recording monitors were used continuously 12 hours before and during 48 hours after immunization to document prolonged apnea and bradycardia. Results The incidence of adverse cardiorespiratory events post-immunization (PI) was higher in the whole group with 40% of the infants having apneas >3 seconds longer than before immunization (BI), and more prolonged events of bradycardia. The longest apnea observed PI was 20 seconds. Mean PI desaturations were more pronounced (76% PI vs. 67% BI; p<0.05). Furthermore, during the first 24 hours PI the mean oxygen saturation was lower, and the mean heart rate was significantly higher. In 40% of the children the second immunization was performed under continuous cardiorespiratory monitoring. Conclusions Preterm infants who received diphtheria-tetanus-pertussis-inactivated polio-Haemophilus influenzae type B and pneumococcal vaccine before discharge were more likely to temporarily experience prolonged apnea and bradycardia after immunization. Continuous mobile event monitoring of these infants was a helpful tool to detect clinically significant cardiorespiratory events.

    ABSTRACT: Objective: The study investigated the ability of near-infrared spectroscopy (NIRS) to detect subgroups of preterm infants who benefit most from red blood cell (RBC) transfusion in regard to cerebral/renal tissue oxygenation (i) and the number of general oxygen desaturation below 80% (SaO(2) <80%) (ii). Study design: Cerebral regional (crSO(2)) and peripheral regional (prSO(2)) NIRS parameters were recorded before, during, immediately after and 24 h after transfusion in 76 infants. Simultaneously, SaO(2) <80% were recorded by pulse oximetry. To answer the basic question of the study, all preterm infants were divided into two subgroups according to their pretransfusion crSO(2) values (<55% and ≥55%). This cutoff was determined by a k-means clustering analysis. Result: crSO(2) and prSO(2) increased significantly in the whole study population. A stronger increase (P<0.0005) of both was found in the subgroup with pretransfusion crSO(2) values <55%. Regarding the whole population, a significant decrease (P<0.05) of episodes with SaO(2) <80% was observed. The subgroup with crSO(2) baselines <55% had significant (P<0.05) more episodes with SaO(2) <80% before transfusion. During and after transfusion, the frequency of episodes with SaO(2) <80% decreased more in this group compared with the group with crSO(2) baselines ≥55%. Conclusion: NIRS measurement is a simple, non-invasive method to monitor regional tissue oxygenation and the efficacy of RBC transfusion. Infants with low initial NIRS values benefited most from blood transfusions regarding SaO(2) <80%, which may be important for their general outcome.

    ABSTRACT: The accurately timed extubation of ventilated ELBW preterm infants is still a problem. With different data systems the attempt has been made to more accurately predict the successful extubation of these infants. However, there do not yet exist any satisfying solutions. We retrospectively analysed 66 ELBW preterm infants who were endotracheal intubated and ventilated within 24 h postnatal. Basic data, clinical and ventilation data immediately before planned extubation and in several intervals during the following 24 h, as well as outcome variables at discharge were interpreted. 51 patients were successfully extubated (EE-group), 15 (22.7%) failed extubation (reintubation within 48 h after extubation, EV-group). Immediately before extubation in the EE-group there was found a significantly higher inspiratory oxygen concentration (FiO2) in comparison to the EV-group (0.25 vs. 0.3; p=0.01). After the extubation attempt the inspiratory oxygen concentration stayed lower in the EE-group, whereas in the EV-group it rose remarkably (2 h after ext.: 0.26 vs. 0.4; p<0.001). Neither of the basic data showed any significant difference. The outcome analysis indicated a longer intensive care in the EV-group and a trend towards increased BPD and ROP. The study shows that for ELBW preterm infants the inspiratory oxygen concentration is especially important to predict a successful extubation. According to our data, the inspiratory oxygen demand before and immediately after extubation establishes the essential difference between successfully extubated and reintubated infants.

    ABSTRACT: Background: The criteria for erythrocyte transfusion in stable premature infants are currently controversial. Haemodynamic measurements are not common in transfusion practice. The purpose of this study was to determine whether haemodynamic measurements could be helpful as objective criterion for transfusion decisions. We, therefore, evaluated clinical and haemodynamic changes in stable, anaemic, premature infants before and after transfusion using our current blood transfusion protocol based on a haematocrit threshold (<24%) and the neonatologist's discretion. Material and methods: Stable premature infants with a haematocrit level ≤30% were prospectively enrolled into the study. Cerebral, intestinal and renal blood flow velocities, cardiac function parameters and vital signs were measured up to three times following every routine haematocrit analysis. Moreover, transfused infants were evaluated three more times: directly before transfusion, and 24 hours and 72 hours after transfusion. Results: Thirty-six infants were enrolled and 23 of them were transfused. Subgroup analysis of transfused infants showed a significant decrease in cerebral blood flow velocities, cardiac output and heart rate. These changes persisted after transfusion. In the entire cohort, the degree of anaemia correlated with the increase of cerebral blood flow velocities, heart rate and cardiac output. Discussion: Cerebral blood velocities in the anterior cerebral artery might represent an objective Doppler sonographic criterion indicating the need for transfusion. The measurement of these velocities is non-invasive and quick and easy to perform. However, a randomised, controlled trial is necessary before a formal recommendation can be made.

    ABSTRACT: We evaluated blood culture-proven sepsis episodes occurring in microclusters in very-low-birth-weight infants born in the German Neonatal Network (GNN) during 2009-2010. Thirty-seven centers participated in GNN; 23 centers enrolled ≥50 VLBW infants in the study period. Data quality was approved by on-site monitoring. Microclusters of sepsis were defined as occurrence of at least two blood-culture proven sepsis events in different patients of one center within 3 months with the same bacterial species. For microcluster analysis, we selected sepsis episodes with typically cross-transmitted bacteria of high clinical significance including gram-negative rods and Enterococcus spp. In our cohort, 12/2110 (0.6%) infants were documented with an early-onset sepsis and 235 late-onset sepsis episodes (≥72 h of age) occurred in 203/2110 (9.6%) VLBW infants. In 182/235 (77.4%) late-onset sepsis episodes gram-positive bacteria were documented, while coagulase negative staphylococci were found to be the most predominant pathogens (48.5%, 95%CI: 42.01-55.01). Candida spp. and gram-negative bacilli caused 10/235 (4.3%, 95%CI: 1.68% -6.83%) and 43/235 (18.5%) late-onset sepsis episodes, respectively. Eleven microclusters of blood-culture proven sepsis were detected in 7 hospitals involving a total 26 infants. 16/26 cluster patients suffered from Klebsiella spp. sepsis. The median time interval between the first patient's Klebsiella spp. sepsis and cluster cases was 14.1 days (interquartile range: 1-27 days). First patients in the cluster, their linked cases and sporadic sepsis events did not show significant differences in short term outcome parameters. Microclusters of infection are an important phenomenon for late-onset sepsis. Most gram-negative cluster infections occur within 30 days after the first patient was diagnosed and Klebsiella spp. play a major role. It is essential to monitor epidemic microclusters of sepsis in surveillance networks to adapt clinical practice, inform policy and further improve quality of care.

    ABSTRACT: Abstract Background: Infants with extremely low birth weight uniformly develop anemia of prematurity and frequently require red blood cell transfusions (RBCTs). Although RBCT is widely practiced, the indications remain controversial in the absence of conclusive data on the long-term effects of RBCT. Objectives: To summarize the current equipoise and to outline the study protocol of the ‘Effects of Transfusion Thresholds on Neurocognitive Outcome of extremely low birth-weight infants (ETTNO)’ study. Methods: Review of the literature and design of a large pragmatic randomized controlled trial of restrictive versus liberal RBCT guidelines enrolling 920 infants with birth weights of 400–999 g with long-term neurodevelopmental follow-up. Results and Conclusions: The results of ETTNO will provide definite data about the efficacy and safety of restrictive versus liberal RBCT guidelines in very preterm infants.

    ABSTRACT: To characterize glucose tolerance and adipokine serum levels in a cohort of women shortly after delivery. A study population of healthy pregnant women (n = 65) was invited to undergo a standardized oral glucose tolerance test within 24 h after delivery at the University Hospital of Leipzig. As controls, 30 nonpregnant healthy, lean women were studied. Glucose, insulin, proinsulin, c-peptide, leptin, adiponectin, and soluble leptin receptor levels were compared in cases and controls by using the Mann-Whitney U two-sample statistics and correlation according to Spearman. As compared to normal glucose tolerant (NGT) women postpartum, fasting c-peptide levels were significantly higher (NGT mothers = 0.23 nmol/L, controls: 0.49 nmol/L, p < 0.001), whereas proinsulin serum levels were significantly lower in nonpregnant controls (NGT mothers = 1.37 pmol/L, controls = 1.00 pmol/L, p = 0.05). Considering fasting adiponectin values, postpartum adiponectin was significantly decreased compared with controls (NGT mothers = 6.9 μg/L, controls = 8.9 μg/L, p = 0.05). Fasting serum levels of leptin (NGT mothers = 17 ng/mL, controls = 10.6 ng/mL, p < 0.009) and soluble leptin receptor (NGT mothers = 34.4 ng/mL, controls = 17.7 ng/mL, p < 0.001) were increased postpartum. We found significantly lower adiponectin and higher leptin sera levels in women postpartum as compared to nonpregnant women. In addition, adipokine serum levels shortly after delivery were related to parameters of adiposity and glucose tolerance. We hypothesize that women in the post-delivery period exhibit biochemical features resembling metabolic syndrome, impaired glucose tolerance, and derangement of the adipokine system.

    ABSTRACT: ATP-binding cassette member A 3 (ABCA3) plays a critical role for the transport of surfactant phospholipids into the lamellar bodies of type II alveolar epithelial cells. Term infants carrying the E292V missense mutation of the gene encoding ABCA3 are likely to develop respiratory distress syndrome, and the mutation has also been linked to interstitial lung disease in paediatric patients. The aim of this study was to investigate the association of the E292V genotype with pulmonary morbidity in a large cohort of very-low-birth-weight (VLBW) infants. We performed a genetic association study with a prospective, population-based multi-centre cohort of 3177 VLBW infants born in 16 German study centres between 2003 and 2009 (German Neonatal Network). The ABCA3 genotype was determined by restriction fragment length polymorphism-PCR in genomic DNA samples derived from buccal swabs. In a large cohort of 3177 VLBW infants, 11 individuals were found to be heterozygote for the E292V mutation (0.34%). After stratification according to ABCA3 genotype, no differences were noted for clinical characteristics, necessary treatments and neonatal pulmonary outcomes. Within the size limits of our study cohort, the ABCA3 missense mutation E292V had no remarkable effect on pulmonary outcome in VLBW infants. Present results do not rule out the possibility that E292V phenotype is associated with minor difference in the morbidity.

    ABSTRACT: The adipokine leptin has been detected in human breast milk, but its effect on postnatal growth and development remains largely unclear. We hypothesized that leptin could affect infant's body weight gain during early lactation in the first 6 mo of life. Therefore, we evaluated leptin levels in maternal serum and breast milk of 23 healthy, lactating mothers and their neonates in a prospective, longitudinal study. Leptin concentration was quantified by a commercially available human leptin RIA. Our results showed that leptin levels in breast milk were 22-fold lower than in maternal serum, but both parameters were positively correlated to each other (r = 0.431, p = 0.001) and to maternal BMI (serum: r = 0.512, p < 0.001; milk: r = 0.298, p < 0.001) over 6 mo of lactation. A negative association was found between breast milk leptin levels during the first week after delivery and the infant weight gain from the end of the first to the sixth month (r = -0.681, p = 0.007). This suggests that milk-borne leptin provides a link between maternal body composition and infant growth and development and plays a critical role in regulating appetite and food intake during early infancy.

    ABSTRACT: To determine whether the tumor necrosis factor-α -308 G/A polymorphism is associated with blood culture-proven sepsis in two large cohorts of very-low-birth-weight infants. Genetic association studies. Prospective, population-based, multicentered cohort of 1944 very-low-birth-weight infants born in 14 German study centers between 2003 and 2008 and 976 mothers, and a second prospective cohort of 926 very-low-birth-weight infants born in 2009 (German Neonatal Network). In cohort I, 344 of 1944 (18.2%) very-low-birth-weight infants had at least one episode of blood culture-proven sepsis develop. The sepsis incidence stratified to genotype was 19.3% for G/G, 15.8% for G/A, 10.0% for A/A genotype (Cochrane-Armitage trend test: G/G vs. G/A: odds ratio, 1.32; 95% confidence interval, 1.03-1.71; G/G vs. A/A: odds ratio, 1.74; 95% confidence interval, 1.06-2.91; p = .03). There was a trend for association of tumor necrosis factor-α -308 A/G genotype with late-onset sepsis episodes (incidence: 17.2% for G/G, 12.5% for G/A, 10.0% for A/A genotype; Cochrane-Armitage trend test: G/G vs. G/A: odds ratio, 1.43; 95% confidence interval, 1.09-1.9; G/G vs. A/A: odds ratio, 2.05; 95% confidence interval, 1.19-3.56; p = .009). However, after adjustment for multiple testing, no significant associations were found. Furthermore, the genotype of the investigated 976 mothers had no impact on sepsis risk for their very-low-birth-weight infants. We additionally studied a second prospective cohort of 926 very-low-birth-weight infants and found no associations with sepsis risk. No association was found between the tumor necrosis factor-α -308 G/A polymorphism blood culture-proven sepsis in two large cohorts of very-low-birth-weight infants. A recent meta-analysis demonstrated that the tumor necrosis factor-α -308 A allele is associated with higher sepsis risk in adult cohorts. Thus, potential differences between adults and infants need to be incorporated in future study designs evaluating risk profiles for sepsis.

    ABSTRACT: Rapid enteral feeding volume advancement in preterm infants can reduce the use of intravenous fluids. This practice may decrease the hazards of intravenous infusion solutions and potentially the morbidity rate. Several cohort trials demand the standardised nutritional regimen to reduce the complications and the time to reach full enteral feeds. to determine whether using a standardized nutritional regimen the rapid enteral feeding advancement in preterm infants is practicable without increasing the incidence of feeding complications. A prospective, randomized, controlled trial was performed in 99 preterm infants, birth weight ≤1,750 g. Group ST (standardized nutritional regimen) received breast human milk according to a standardized nutritional regimen. Group IN (individual nutritional regimen) received breast human milk or semi-elemental nutrition (Pregomin(®) Milupa) depending on enteral problems of the infant. The feeding volume advancement in the IN-Group was decided individually. The main outcome measure was time to reach full enteral feedings. Infants in the ST-Group achieved full enteral feedings after 14.93±9.95 (median 12) d, infants in the IN-Group after 16.23±10.86 (median 14) d. The difference between the groups was significant only in small for gestational age (SGA) infants: ST-Group 10.20±4.78 (median 8.5) vs. IN-Group 16.73±8.57 (Median 15) days (p=0.045). The weight gain was similar in both groups. Infants in ST-Group achieved full enteral feedings having 116% of birth weight, infants in IN-Group 122% of birth weight. This difference was not significant (p=0.195). The incidence of NEC (necrotizing enterocolitis, 4%) and other complications were low in both groups. The diagnosis "feeding complications" was described in IN-Group in 14 vs. 7 infants in ST-Group. SGA-infants profit from the enteral feeding advancement by using a standardized nutritional regimen. These infants achieved full enteral feedings sooner then the SGA-infants, who did not feed by using a standardized nutritional regimen. A standardized nutritional regimen can be realized in clinical routine and is by strict clinical observation practicable without increasing the incidence of feeding complications.
