Objective To assess patent ductus arteriosus treatment variation between Swiss perinatal centers and to determine its effect on outcome in a population-based setting. Study design This was a retrospective cohort study of infants born less than 28 weeks of gestation between 2012 and 2017. Outcomes between surgically ligated and pharmacologically treated infants as well as infants born in centers performing ≤10% ligation (“low” group) and >10% (“high” group) were compared using logistic regression and 1:1 propensity score matching. Matching was based on case-mix and preligation confounders: intraventricular hemorrhages grades 3-4, necrotizing enterocolitis, sepsis, and ≥28 days’ oxygen supply. Results Of 1389 infants, 722 (52%) had pharmacologic treatment and 156 (11.2%) received surgical ligation. Compared with infants who received pharmacologic treatment, ligated infants had greater odds for major morbidities (OR 2.09, 95% CI 1.44-3.04) and 2-year neurodevelopmental impairment (OR 1.81, 95% CI 1.15-2.84). Mortality was comparable after restricting the cohort to infants surviving at least until day 10 to avoid survival bias. In the “low” group, 34 (4.9%) of 696 infants were ligated compared with 122 (17.6%) of 693 infants in the “high” group. Infants in the “high” group had greater odds for major morbidities (OR 1.49, 95% CI 1.11-2.0). Conclusions Our analysis identified a burden on infants receiving surgical ligation vs pharmacologic treatment in a population-based setting where there was no agreed-on common procedure. These results may guide a revision of patent ductus arteriosus treatment practice in Switzerland.

Summary Background Neonatal deaths now account for 47% of all deaths in children younger than 5 years globally. More than a third of newborn deaths are due to preterm birth complications, which is the leading cause of death. Understanding the causes and factors contributing to neonatal deaths is needed to identify interventions that will reduce mortality. We aimed to establish the major causes of preterm mortality in preterm infants in the first 28 days of life in Ethiopia. Methods We did a prospective, cross-sectional, observational study in five hospitals in Ethiopia. Study participants were preterm infants born in the study hospitals at younger than 37 gestational weeks. Infants whose gestational age could not be reliably estimated and those born as a result of induced abortion were excluded from the study. Data were collected on maternal and obstetric history, clinical maternal and neonatal conditions, and laboratory investigations. For neonates who died of those enrolled, consent was requested from parents for post-mortem examinations (both complete diagnostic autopsy and minimally invasive tissue sampling). An independent panel of experts established the primary and contributory causes of preterm mortality with available data. Findings Between July 1, 2016, to May 31, 2018, 4919 preterm infants were enrolled in the study and 3852 were admitted to neonatal intensive care units. By 28 days of post-natal age, 1109 (29%) of those admitted to the neonatal intensive care unit died. Complete diagnostic autopsy was done in 441 (40%) and minimally invasive tissue sampling in 126 (11%) of the neonatal intensive care unit deaths. The main primary causes of death in the 1109 infants were established as respiratory distress syndrome (502 [45%]); sepsis, pneumonia and meningitis (combined as neonatal infections; 331 [30%]), and asphyxia (151 [14%]). Hypothermia was the most common contributory cause of preterm mortality (770 [69%]). The highest mortality occurred in infants younger than 28 weeks of gestation (89 [86%] of 104), followed by infants aged 28–31 weeks (512 [54%] of 952), 32–34 weeks (349 [18%] of 1975), and 35–36 weeks (159 [8%] of 1888). Interpretation Three conditions accounted for 89% of all deaths among preterm infants in Ethiopia. Scale-up interventions are needed to prevent or treat these conditions. Further research is required to develop effective and affordable interventions to prevent and treat the major causes of preterm death. Funding Bill & Melinda Gates Foundation.

AIMS OF THE STUDY To assess whether the COVID-19 pandemic caused by SARS-CoV-2 had an impact on incidence, treatment or major adverse short-term outcome of preterm-born infants in Switzerland. METHODS Retrospective cohort study of preterm infants born in 2020 based on two independent data sources from the Swiss Federal Statistics Office (FSO) and SwissNeoNet. Based on FSO data, we calculated the odds ratios for extremely preterm (22-27 weeks gestation), very preterm (28-31 weeks gestation), and late preterm (32-36 weeks gestation) births during the pandemic. Based on SwissNeoNet data of infants born between 22 and 31 weeks gestation, we compared infants born during the Swiss lockdown period in 2020 with infants born during the same period between 2015 and 2019, all infants of 2020 with all infants between 2015 and 2019 and infants born to mothers tested SARS-CoV-2 positive and negative. Possible associations with the pandemic were tested using logistic regression adjusted for case-mix. As a control, we compared births of 2019 with those of 2015-2018. RESULTS The FSO data revealed equivalent odds for extremely preterm births in 2020 (odds ratio [OR] 1.01, 95% confidence interval [CI] 0.89-1.14), as well as somewhat lower odds ratios for very preterm (OR 0.9, 95% CI 0.82-1.00) and late preterm (OR 0.91, 95% CI 0.88-0.93) births in 2020. A comparison between 2019 and 2015-2018, however, revealed matching odds ratios rendering an association to the pandemic unlikely. In the SwissNeoNet data, 137 infants were born during lockdown in 2020 compared with 134 births per year during 2015-2019. When including all infants, 744 infants were compared to 845 births, respectively. The only difference observed in treatments and short term outcomes between 2020 and the reference years were a higher odds for respiratory distress syndrome (OR 1.6, 95% CI 1.08-2.37) and provision of continuous positive airway pressure (CPAP) (OR 1.39, 95% CI 1.05-1.84). CONCLUSIONS Our Swiss population-based analysis did not identify the elsewhere reported association between the COVID-19 pandemic and a reduced preterm birth rate. However, we can confirm a possible link between the COVID-19 pandemic and higher odds of respiratory distress syndrome, possibly coupled with CPAP requirements. Further observation of potential effects of the pandemic on health and health care provision to newborns may however be indicated based on the literature available so far and that our data only covers the first 9 months of the current pandemic.

International audience; Introduction Variability of arterial blood pressure (ABP) has been associated with intraventricular hemorrhage in very preterm neonates (VPT) and may predict other brain lesions assessed at term-equivalent of age (TEA). Methods This was a prospective single-center study including VPT with early invasive continuous ABP monitoring and assessed at TEA using brain magnetic resonance imaging (TEA-MRI). The association between early mean ABP (MABP) and TEA-MRI findings was modeled by multivariate logistic regression analysis using covariates selected by the LASSO method. Results Among 99 VPT, the LASSO procedure selected consecutive periods of lowest MABP of 30 min on day 1 (d1) and 10 min on day 2 (d2) as the most relevant durations to predict TEA-MRI findings (OR [95% CI], 1.11 [1.02-1.23], p = 0.03 and 1.13 [1.01-1.27], p = 0.03, respectively). ROC curve analysis showed optimal thresholds at 30.25 mmHg on d1 and 33.25 mmHg on d2. This significant association persisted after adjustment with covariates including birthweight, gestational age, sex, and inotrope exposure. Final models selected by LASSO included the decile of the birthweight and lowest MABP for 30 min on d1 and 10 min on d2, for which the areas under the ROC curve were 74% and 75%, respectively. Conclusion Early continuous ABP monitoring may predict brain TEA-MRI findings in VPT. Impact Early arterial blood pressure monitoring may contribute to predicting brain damage upon MRI at term-equivalent of age for infants born very preterm. Careful blood pressure continuous monitoring in very preterm infants may identify infants at risk of long-term brain damage. Umbilical artery catheterization provides the best option for continuously monitoring arterial blood pressure in very preterm infants.

Background Differences in perception and potential disagreements between parents and professionals regarding the attitude for resuscitation at the limit of viability are common. This study evaluated in healthcare professionals whether the decision to resuscitate at the limit of viability (intensive care versus comfort care) are influenced by the way information on incurred risks is given or received. Methods This is a prospective randomized controlled study. This study evaluated the attitude of healthcare professionals by testing the effect of information given through graphic fact sheets formulated either optimistically or pessimistically. The written educational fact sheet included three graphical presentations of survival and complication/morbidity by gestational age. The questionnaire was submitted over a period of 4 months to 5 and 6-year medical students from the Geneva University as well as physicians and nurses of the neonatal unit at the University Hospitals of Geneva. Our sample included 102 healthcare professionals. Results Forty-nine responders (48%) were students (response rate of 33.1%), 32 (31%) paediatricians (response rate of 91.4%) and 21 (20%) nurses in NICU (response rate of 50%). The received risk tended to be more severe in both groups compared to the graphically presented facts and current guidelines, although optimistic representation favoured the perception of “survival without disability” at 23 to 25 weeks. Therapeutic attitudes did not differ between groups, but healthcare professionals with children were more restrained and students more aggressive at very low gestational ages. Conclusion Written information on mortality and morbidity given to healthcare professionals in graphic form encourages them to overestimate the risk. However, perception in healthcare staff may not be directly transferable to parental perception during counselling as the later are usually naïve to the data received. This parental information are always communicated in ways that subtly shape the decisions that follow.

AIM Epidemiological data on the incidence and risk factors of extravasation of peripheral intravenous catheters (PIVC) in neonates and children are scarce and that is what this study explored. METHODS This was a one-year retrospective study of all neonates and paediatric intensive care patients with at least one recorded PIVC at the Geneva University Hospitals, Switzerland, in 2013. The extravasation rate was determined for all patients, including neonates below 28 days, and for all PIVCs. Multivariate analysis of the associated risk factors was performed. RESULTS We analysed 1300 PIVC in 695 paediatric patients with a median age of 1.5 years. The overall extravasation incidence was 17.6% for all patients and 11.7% for PIVC. The overall incidence rate of PIVC extravasation was 4.5 per 100 catheters days, and the risk was highest in the 201 neonates, at 28.4%. The incidence rate four days after insertion of the PIVC was around three times higher than on day one. Neonates and the in situ duration of PIVCs were associated risk factors (p < 0.001). CONCLUSION Extravasation was frequent and neonates were particularly at risk. Younger age and longer in situ PIVC duration were independent risk factors for extravasation.

Background The current standard treatment of neonates with intestinal perforation is surgery. However, the mortality rate after surgical treatment for intestinal perforation is very high for very low birth weight (VLBW) and extremely low birth weight (ELBW) neonates. In this review, conservative treatment of pneumoperitoneum among VLBW and ELBW neonates is investigated. Methods Between January 2015 and December 2017, data from all of the VLBW and ELBW neonates with pneumoperitoneum who survived without surgical treatment were collected from Shenzhen Maternity and Child Healthcare Hospital in Guangdong, China. Twenty-two neonates with birth weight less than 1500 g were diagnosed with pneumoperitoneum. Following careful evaluation and discussion, eleven were treated conservatively and this was successful in eight. Details of the eight neonates including birth weight, gestational age, gender, risk factors, time of the perforation, treatment and prognosis were retrospectively recorded. A literature review was performed of previously reported cases that had used conservative treatment. Results The median gestational age and birth weight of the eight neonates were 27+ 1 weeks (range 24w+ 3 to 31w+ 6) and 855 g (range 650 g to 1440 g), respectively. Pneumoperitoneum was confirmed by X-ray in all at a median of 8 days of life. They received full parenteral support for a median of 22 days. All eight neonates received a combination of piperacillin-tazobactam and meropenem as first-choice antibiotics, two of them also received fluconazole as anti-fungal medication. Median duration of hospitalisation was 80 days. Conclusions Conservative treatment with careful surveillance may be a practical choice for the VLBW and ELBW neonates with intestinal perforation. Further studies are needed for confirmation.

Periventricular white matter injury is common in very preterm infants and it is associated with long term neurodevelopmental impairments. While evidence supports the protective effects of erythropoetin (EPO) in preventing injury, we currently lack the complete understanding of how EPO affects the emergence and maturation of anatomical brain connectivity and function. In this case-control study, connectomic analysis based on diffusion MRI tractography was applied to evaluate the effect of early high-dose EPO in preterm infants. A whole brain, network-level analysis revealed a sub-network of anatomical brain connections in which connectivity strengths were significantly stronger in the EPO group. This distributed network comprised connections predominantly in the frontal and temporal lobe bilaterally, and the effect of EPO was focused on peripheral and feeder connections of the core structural connectivity network. EPO resulted in a globally increased clustering coefficient, higher global and average local efficiency, while higher strength and increased clustering was found for regions in the frontal lobe and cingulate gyrus. The connectivity network most affected by the EPO treatment showed a steeper increase graph theoretical measures with age compared to the placebo group. Our results demonstrate a weak but widespread effect of EPO on the structural connectivity network and a possible trophic effect of EPO reflected by increasing network segregation, predominantly in local connections., Highlights • Erythropoietin (EPO) is a potential neuroprotective agent in very preterm infants. • EPO leads to increased structural brain connectivity in fronto-temporal regions. • Clustering coefficient, local and global efficiency increases after EPO treatment.

To assess associations between neonatal intensive care unit (NICU)-level patent ductus arteriosus (PDA) treatment rates (pharmacologic or surgical) and neonatal outcomes.This cohort study included infants born at 24-28 weeks of gestation and birth weight1500 g in 2007-2015 in NICUs caring for ≥100 eligible infants in 6 countries. The ratio of observed/expected (O/E) PDA treatment rates was derived for each NICU by estimating the expected rate using a logistic regression model adjusted for potential confounders and network. The primary composite outcome was death or severe neurologic injury (grades III-IV intraventricular hemorrhage or periventricular leukomalacia). The associations between the NICU-level O/E PDA treatment ratio and neonatal outcomes were assessed using linear regression analyses including a quadratic effect (a square term) of the O/E PDA treatment ratio.From 139 NICUs, 39 096 infants were included. The overall PDA treatment rate was 45% in the cohort (13%-77% by NICU) and the O/E PDA treatment ratio ranged from 0.30 to 2.14. The relationship between the O/E PDA treatment ratio and primary composite outcome was U-shaped, with the nadir at a ratio of 1.13 and a significant quadratic effect (P.001). U-shaped relationships were also identified with death, severe neurologic injury, and necrotizing enterocolitis.Both low and high PDA treatment rates were associated with death or severe neurologic injury, whereas a moderate approach was associated with optimal outcomes.

Background Late preterm (LPT) newborns, defined as those born between 34 0/7 and 36 6/7 gestational weeks, have higher short- and long-term morbidity and mortality than term infants (≥37 weeks). A categorization to justify a non-spontaneous LPT delivery has been proposed to distinguish evidence-based from non-evidence-based criteria. This study aims to describe rates and temporal trends of non-spontaneous LPT neonates delivered according to evidence-based or non-evidence-based criteria and to evaluate the number of avoidable LPT deliveries, including severe neonatal morbidity rates and associated risk factors. Methods Retrospective cohort study including all LPT neonates born at a Swiss university maternity unit between January 1, 2002 and December 31, 2012. Trends of LPT neonates and neonatal complications were assessed across time using Poisson regression and risk factors for neonatal complications by logistic regression. Results Among 40,609 singleton live births, 4223 (10.5%) were preterm and 2017 (4.9%) LPT. In the latter group, 26.2% were non-spontaneous (evidence-based: 12.0%; non-evidence-based: 14.2%). The most frequent indications for evidence-based non-spontaneous LPT delivery were severe preeclampsia (51.8%) and abnormal fetal tracing (24.7%). Indications for non-evidence-based non-spontaneous LPT deliveries were hemorrhage (36.2%) and mild preeclampsia (15.7%). LPT birth rates remained stable over time. The rate of neonatal complications after non-evidence-based LPT birth remained high over time (43.8% vs. 43.5% in 2002 and 2012, respectively; P = 0.645), whereas the annual proportion of neonatal complications overall showed a decreasing trend (from 38.0% in 2002 to 33.5% in 2012; P = 0.051). Conclusions LPT birth rates were stable over time, but neonatal complications remained high, particularly after non-evidence-indicated LPT birth. A total of 287 LPT births could have been potentially avoided if an evidence-based protocol for delivery indications had been used. Efforts should be made to avoid non-spontaneous LPT births in order to reduce neonatal complications.

BACKGROUND Therapeutic hypothermia following hypoxic ischaemic encephalopathy in term infants was introduced into Switzerland in 2005. Initial documentation of perinatal and resuscitation details was poor and neuromonitoring insufficient. In 2011, a National Asphyxia and Cooling Register was introduced. AIMS To compare management of cooled infants before and after introduction of the register concerning documentation, neuromonitoring, cooling methods and evaluation of temperature variability between cooling methods. STUDY DESIGN Data of cooled infants before the register was in place (first time period: 2005-2010) and afterwards (second time period: 2011-2012) was collected with a case report form. RESULTS 150 infants were cooled during the first time period and 97 during the second time period. Most infants were cooled passively or passively with gel packs during both time periods (82% in 2005-2010 vs 70% in 2011-2012), however more infants were cooled actively during the second time period (18% versus 30%). Overall there was a significant reduction in temperature variability (p < 0.001) comparing the two time periods. A significantly higher proportion of temperature measurements within target temperature range (72% versus 77%, p < 0.001), fewer temperature measurements above (24% versus 7%, p < 0.001) and more temperatures below target range (4% versus 16%, p < 0.001) were recorded during the second time period. Neuromonitoring improved after introduction of the cooling register. CONCLUSION Management of infants with HIE improved since introducing the register. Temperature variability was reduced, more temperature measurements in the target range and fewer temperature measurements above target range were observed. Neuromonitoring has improved, however imaging should be performed more often.

Aim: Neonatal resuscitation requires minimal equipment, but the immediate availability of expert staff accounts for the largest proportion of the costs. Despite this, staff requirements and timetables are currently planned without comprehensive epidemiologic data. The aim of this study was to evaluate the staffing required for neonatal resuscitations in the delivery room. Methods: We measured attendance for each specific role in a tertiary university-affiliated hospital and for four possible intervention levels: preparation time, basic paediatric care, moderate resuscitation and extended resuscitation. Results: Between 2005 and 2012, resuscitation staff attended 11 561 of the 32 799 births: 27.2% for preparation time, 17.7% for basic paediatric care, 6.4% for moderate resuscitation and 3.5% for extended resuscitation. Moderate and extended resuscitations occurred in roughly 10% of births and evenly during 24-h periods. Basic paediatric care levels were higher during weekday mornings, and extended resuscitations were uniformly distributed. However, there was a drop in all types of interventions around 7 a.m. to 8 a.m., when staff were changing shifts. Conclusion: Moderate and extended resuscitations occurred evenly over 24 h in roughly 10% of births, stressing the importance of having a highly competent neonatal team constantly available. All activities associated with resuscitation were lower during morning shift changes.

Objective:To evaluate the dynamics of bacterial contamination of healthcare workers' (HCWs) hands during neonatal care.Setting:The 20-bed neonatal unit of a large acute care teaching hospital in Geneva, Switzerland.Methods:Structured observation sessions were conducted. A sequence of care began when the HCW performed hand hygiene and ended when the activity changed or hand hygiene was performed again. Alcohol-based handrub was the standard procedure for hand hygiene. An imprint of the five fingertips of the dominant hand was obtained before and after hand hygiene and at the end of a sequence of care. Regression methods were used to model the final bacterial count according to the type and duration of care and the use of gloves.Results:One hundred forty-nine sequences of care were observed. Commensal skin flora comprised 72.4% of all culture-positive specimens (n = 360). Other microorganisms identified were Enterobacteriaceae (n = 55, 13.8%);Staphylococcus aureus(n = 10, 2.5%); and fungi (n = 7,1.8%). Skin contact, respiratory care, and diaper change were independently associated with an increased bacterial count; the use of gloves did not fully protect HCWs' hands from bacterial contamination.Conclusions:These data confirm that hands become progressively contaminated with commensal flora and potential pathogens during neonatal care, and identify activities at higher risk for hand contamination. They also reinforce the need for hand hygiene after a sequence of care, before starting a different task, and after glove removal.

Background Quality improvement in health care requires identification of areas in need of improvement by comparing processes and patient outcomes within and between health care providers. It is critical to adjust for different case-mix and outcome risks of patient populations but it is currently unclear which approach has higher validity and how limitations need to be dealt with. Our aim was to compare 3 approaches towards risk adjustment for 7 different major quality indicators in neonatal intensive care (21 models). Methods We compared an indirect standardization, logistic regression and multilevel approach. Parameters for risk adjustment were chosen according to literature and the condition that they may not depend on processes performed by treating clinics. Predictive validity was tested using the mean Brier Score and by comparing area under curve (AUC) using high quality population based data separated into training and validation sets. Changes in attributional validity were analysed by comparing the effect of the models on the observed-to-expected ratios of the clinics in standardized mortality/morbidity ratio charts. Results Risk adjustment based on indirect standardization revealed inferior c-statistics but superior Brier scores for 3 of 7 outcomes. Logistic regression and multilevel modelling were equivalent to one another. C-statistics revealed that predictive validity was high for 8 and acceptable for 11 of the 21 models. Yet, the effect of all forms of risk adjustment on any clinic’s comparison with the standard was small, even though there was clear risk heterogeneity between clinics. Conclusions All three approaches to risk adjustment revealed comparable results. The limited effect of risk adjustment on clinic comparisons indicates a small case-mix influence on observed outcomes, but also a limited ability to isolate quality improvement potential based on risk-adjustment models. Rather than relying on methodological approaches, we instead recommend that clinics build small collaboratives and compare their indicators both in risk-adjusted and unadjusted form together. This allows qualitatively investigating and discussing the residual risk-differences within networks. The predictive validity should be quantified and reported and stratification into risk groups should be more widely used to correct for confounding.

Sepsis is an important cause of morbidity and mortality in neonates and clinicians are typically required to administer empiric antibiotics while waiting for blood culture results. However, prolonged and inappropriate use of antibiotics is associated with various complications and adverse events. Better tools to rapidly rule out bacterial infections are therefore needed.We aimed to assess the negative predictive value of PCR coupled with Electrospray Ionization Mass Spectrometry (PCR/ESI-MS) compared to conventional blood cultures in neonatal sepsis.Prospective observational study.All consecutive neonates (28days old) with clinical suspicion of sepsis. Samples for PCR/ESI-MS analysis were collected at the same time as samples for the blood culture, before the initiation of antibiotics.Our primary objective was to evaluate the negative predictive value of PCR/ESI-MS for the detection of bacteria in the bloodstream of newborns with suspected sepsis. Our secondary objective was the evaluation of the sensitivity, specificity and positive predictive value of the PCR/ESI-MS in such a neonatal population.We analysed 114 samples over 14months. The median age and weight were 32weeks+3days and 1840g, respectively. Two patients had negative PCR/ESI-MS results, but positive blood cultures. Overall, the negative predictive value was 98% (95%CI: 92% to 100%).Based on these results, PCR/ESI-MS analysis of blood samples of neonates with suspected sepsis appears to have a very good negative predictive value when compared to blood cultures as gold standard. This novel test might allow for early reassessment of the need for antibiotics.

Objective To examine the relationships between intensity of delivery room resuscitation and short- and long-term outcomes of very low birth weight infants enrolled in the Caffeine for Apnea of Prematurity (CAP) Trial. Study design The CAP Trial enrolled 2006 infants with birthweights between 500 and 1250 g who were eligible for caffeine therapy. All levels of delivery room resuscitation were recorded in study participants. We divided infants in 4 groups of increasing intensity of resuscitation: minimal, n = 343; bag-mask ventilation, n = 372; endotracheal intubation, n = 1205; and cardiopulmonary resuscitation (chest compressions/epinephrine), n = 86. We used multivariable logistic regression models to compare outcomes across the 4 groups. Results The observed rates of death or disability, death, cerebral palsy, cognitive deficit, and hearing loss at 18 months increased with higher levels of resuscitation. Risk of bronchopulmonary dysplasia, severe retinopathy of prematurity, and brain injury also increased with higher levels of resuscitation. Adjustment for prognostic variables reduced the differences between the groups for most outcomes. Only the adjusted rates of bronchopulmonary dysplasia and severe retinopathy remained significantly higher after more intense resuscitation. Conclusions In CAP Trial participants, the risk of death or neurodevelopmental disability at 18 months did not increase substantially with increasing intensity of delivery room resuscitation.

Objective To determine whether the benefits of caffeine vary in three subgroups of 2006 participants in the Caffeine for Apnea of Prematurity (CAP) trial. Study design Post-hoc subgroup analyses were performed on the basis of: (1) indication for commencement of study drug: treat apnea, prevent apnea, or facilitate extubation; (2) positive pressure ventilation (PPV) at randomization: endotracheal tube (ETT), noninvasive ventilation, or none; and (3) timing of commencement of study drug: early or late (≤3 versus >3 days). Outcomes assessed were those showing treatment effects in the original analyses. We investigated the consistency of caffeine effects by using regression models that incorporated treatment/subgroup factor interactions. Results There was little evidence of a differential treatment effect of caffeine in subgroups defined by the clinical indication for starting study drug. The size and direction of the caffeine effect on death or disability differed depending on PPV at randomization ( P = .03). Odds ratios (95% CI) were: no support, 1.32 (0.81-2.14); noninvasive support, 0.73 (0.52-1.03); and ETT, 0.73 (0.57-0.94). Adjustment for baseline factors strengthened this effect ( P = .02). Starting caffeine early resulted in larger reductions in days of respiratory support. Postmenstrual age at time of discontinuing PPV was shorter with earlier treatment ( P = .01). Mean differences (95% CI) were: early, 1.35 weeks (0.90-1.81); and late 0.55 weeks (–0.11-0.99). Adjustment for baseline factors weakened this effect ( P = .03). Conclusions There is evidence of variable beneficial effects of caffeine. Infants receiving respiratory support appeared to derive more neurodevelopmental benefits from caffeine than infants not receiving support. Earlier initiation of caffeine may be associated with a greater reduction in time on ventilation.

OBJECTIVE. To determine the age-stratified risk of intrapartum and neonatal mortality as well as morbidities of clinical relevance after elective cesarean delivery (ECD).METHODS. This work was a cohort study including 56 549 prospectively recorded late-preterm and term deliveries. We analyzed the effect of cesarean delivery (CD) before the onset of labor on the following multiple neonatal outcomes before hospital discharge, compared with planned vaginal delivery (PVD) and emergency CD: mortality, birth depression, special care admission, and respiratory morbidity. We adjusted for confounders by multivariate analysis and stratified the risk according to gestational age (GA).RESULTS. Mortality and morbidities had a strong GA-related trend with the lowest incidences consistently found between 38 and 40 weeks of gestation independent of delivery mode. Compared with infants delivered via PVD, infants delivered via ECD had significantly higher rates of mortality (adjusted risk ratio [aRR]: 2.1), risk of special care admission (aRR: 1.4), and respiratory morbidity (aRR: 1.8) but not of depression at birth (aRR: 1.1). Compared with emergency CD, newborns delivered via ECD had less depression at birth (aRR: 0.6) and admission to special care (aRR: 0.8), but mortality (aRR: 0.8) and respiratory morbidity (aRR: 1.0) rates were similar.CONCLUSIONS. Gestational age–specific risk estimates are lowest between 38 and 40 weeks and should be included in the informed-consent process. The information should also be used to allow for appropriate preparation with respect to adequate staff and equipment. ECD is consistently associated with increased intrapartum and neonatal mortality, risk of admission, and respiratory morbidity compared with PVD and has no advantage over emergency CD in terms of mortality. Neonatal morbidities are lower after ECD than emergency CD only with term births. Our data provide evidence that ECD should not be performed before term.

Background: Until recently, the preparation of paediatric parenteral nutrition formulations in our institution included re-transcription and manual compounding of the mixture. Although no significant clinical problems have occurred, re-engineering of this high risk activity was undertaken to improve its safety. Several changes have been implemented including new prescription software, direct recording on a server, automatic printing of the labels, and creation of a file used to pilot a BAXA MM 12 automatic compounder. The objectives of this study were to compare the risks associated with the old and new processes, to quantify the improved safety with the new process, and to identify the major residual risks. Methods: A failure modes, effects, and criticality analysis (FMECA) was performed by a multidisciplinary team. A cause-effect diagram was built, the failure modes were defined, and the criticality index (CI) was determined for each of them on the basis of the likelihood of occurrence, the severity of the potential effect, and the detection probability. The CIs for each failure mode were compared for the old and new processes and the risk reduction was quantified. Results: The sum of the CIs of all 18 identified failure modes was 3415 for the old process and 1397 for the new (reduction of 59%). The new process reduced the CIs of the different failure modes by a mean factor of 7. The CI was smaller with the new process for 15 failure modes, unchanged for two, and slightly increased for one. The greatest reduction (by a factor of 36) concerned re-transcription errors, followed by readability problems (by a factor of 30) and chemical cross contamination (by a factor of 10). The most critical steps in the new process were labelling mistakes (CI 315, maximum 810), failure to detect a dosage or product mistake (CI 288), failure to detect a typing error during the prescription (CI 175), and microbial contamination (CI 126). Conclusions: Modification of the process resulted in a significant risk reduction as shown by risk analysis. Residual failure opportunities were also quantified, allowing additional actions to be taken to reduce the risk of labelling mistakes. This study illustrates the usefulness of prospective risk analysis methods in healthcare processes. More systematic use of risk analysis is needed to guide continuous safety improvement of high risk activities.

Forty Escherichia coli strains isolated primarily from neonatal meningitis, urinary tract infections and feces were screened for the presence of virulence genes with a newly developed microarray on the array tube format. A total of 32 gene probes specific for extraintestinal as well as intestinal E. coli pathotypes were included. Eighty-eight percent of the analyzed strains were positive for the K1-specific probe on the microarray and could be confirmed with a specific antiserum against the K1 capsular polysaccharide. The gene for the hemin receptor ChuA was predominantly found in 95% of strains. Other virulence genes associated with K1 and related strains were P, S, and F1C fimbriae specific for extraintestinal E. coli , the genes for aerobactin, the α-hemolysin and the cytotoxic necrotizing factor. In two strains, the O157-specific catalase gene and the gene for the low-molecular-weight heat-stable toxin AstA were detected, respectively. A total of 19 different virulence gene patterns were observed. No correlation was observed between specific virulence gene patterns and a clinical outcome. The data indicate that virulence genes typical of extraintestinal E. coli are predominantly present in K1 strains. Nevertheless, some of them can carry virulence genes known to be characteristic of intestinal E. coli . The distribution and combination of virulence genes show that K1 isolates constitute a heterogeneous group of E. coli.

Cutaneous congenital candidiasis (CCC) is a very rare disease of the term or premature infant consisting of a generalized rash at or shortly after birth usually without other signs or symptoms. The presence of white microabscesses on the placenta and umbilical cord of an infant with such a rash must suggest the diagnosis of CCC, which is always secondary to Candida chorioamnionitis but may pass unrecognized. Despite the high prevalence of vulvo-vaginitis in pregnant women, Candida chorioamnionitis is rare and CCC remains apparently extremely rare with just some hundred cases described. However, as the condition is essentially benign and self-limited, underdiagnosis is likely. As occasional systemic spread of Candida infection is described and maternal complications may arise, diagnosis and a close follow-up or treatment is of importance. We present two cases of CCC, stressing the importance of sharing clinical findings between obstetrician and neonatologist for the diagnosis and subsequent management.

Introduction Point of care devices (POCT) are used for coagulation evaluation in adults. Reduced blood volumes and the direct use of whole blood allow studies when venous puncture is difficult, such as in newborns. Elimination of sample transport is attractive for use in emergencies and intensive care. Objective To prospectively compare neonatal coagulation parameters measured by the GEM®PCL POCT versus a central laboratory. Materials and Methods Prothrombin Time (PT) and activated Partial Thromboplastin Time (aPTT) were performed on whole cord blood (POCT) and plasma (central laboratory) collected from consecutive newborns at Geneva University Hospitals. Agreement was assessed with a Bland & Altman plot and intra-class correlation coefficient (ICC) in 213 newborns cord blood; intra-assay variability (repeatability) was assessed using ICC and coefficient of variation (CV). Results 189 samples were available for the agreement analysis, 24 were excluded for technical problems. The 95% limits of agreements in the Bland & Altman plot ranged from -5.6 to 11.6 and from -39.6 to 11.6 seconds for the PT and aPTT, respectively. The ICC between the two methods was 0.28 (CI 95% 0.06 to 0.47) for PT and 0.20 (CI 95% -0.06 to 0.42) for aPTT. Repeatability (ICC) on the 43 eligible samples was 0.46 (CI 95% 0.19 to 0.67) for PT and 0.52 (CI 95% 0.26 to 0.71) for aPTT. The CV was 10.6% and 12% for PT and aPTT, respectively. Conclusions In newborn cord blood, PT and aPTT measurements with the GEM®PCL POCT had poor agreement with the central laboratory and poor repeatability.

Our institution's gentamicin dosing and therapeutic drug monitoring (TDM) practices for newborns were suspected to be very heterogeneous. Once-daily dosing (ODD) or extended-interval dosing (EID) and trough concentration measurement were recommended. Clinical decision support guidelines were developed and implemented as clinical decision support in the computerized prescriber order entry system. Impact on dosing, TDM practices, and blood sampling were evaluated.A 1-year retrospective historically controlled study before (April 2008-March 2009) and after the implementation of guidelines (January 2010-December 2010) for newborns (30 days of life) receiving gentamicin. Blood concentrations (% of peak concentrations sampled, % of patients with zero or one concentration sampled, % of trough concentrations ≤1 mg/L) and dose regimen (ODD/EID) were compared between groups. Factors potentially associated with gentamicin concentration were analyzed (multivariate analysis).One hundred thirty-two (postguidelines) versus 102 (preguidelines) patients were included (median gestational age: 34.3 versus 35.8 weeks, P0.05). After implementation of the guidelines, an ODD/EID regimen was almost exclusively used (97.7% versus 61.6%, P0.001), the percentage of peak concentrations (0.9% versus 17.2%, P0.001) and the number of blood samples per patient (87.1% having 0 or 1 concentration measured versus 48.0, P0.001) sharply reduced. A significantly higher percentage of trough concentrations were ≤1 mg/L (68.5% versus 33.0%, P0.001). The probability of a trough concentration ≤1 mg/L increased with an ODD/EID regimen (odds ratio, 7.23; 95% confidence interval: 3.48-15.0, P0.001) and in the postguidelines group (odds ratio, 2.02; 95% confidence interval: 1.01-4.02, P = 0.045).Guideline implementation generated a sharp reduction in blood sampling. Clinical benefits of better gentamicin dosing and TDM practices were evident. Cost-effectiveness and clinical benefit of reduced blood sampling should be evaluated.

BACKGROUND: Maternal-infant transmission of hepatitis B virus (HBV) during birth carries a high risk for chronic HBV infection in infants with frequent subsequent development of chronic disease. This can be efficiently prevented by early immunization of exposed newborns. The purpose of this study was to determine the compliance with official recommendations for prevention of perinatal HBV transmission in hepatitis B surface antigen (HBsAg) exposed infants. METHODS:: Records of pregnant women at 4 sites in Switzerland, admitted for delivery in 2005 and 2006, were screened for maternal HBsAg testing. In HBsAg-exposed infants, recommended procedures (postnatal active and passive immunization, completion of immunization series, and serological success control) were checked. RESULTS: Of 27,131 women tested for HBsAg, 194 (0.73%) were positive with 196 exposed neonates. Of these neonates, 143 (73%) were enrolled and 141 (99%) received simultaneous active and passive HBV immunization within 24 hours of birth. After discharge, the HBV immunization series was completed in 83%. Only 38% of children were tested for anti-HBs afterwards and protective antibody values (

We evaluated the tolerance to immunization of 64 very low birth weight preterm infants. Thirty-three of the infants experienced a cardiorespiratory event after the first vaccination, and 6 of these 33 (18%) had a recurrence after the second vaccination, including 2 infants previously discharged to home. A cardiorespiratory event associated with the first vaccination was the sole risk factor for recurrence identified.

Congenital lingual cysts are rare congenital tumors of the oropharynx, which should be suspected when the tongue appears enlarged by a mass. Prenatal diagnosis by ultrasound allows for an optimal management at the time of delivery because the mass can obstruct the airways. Unless the cyst enlarges and hinders feeding or breathing, surgical treatment is indicated only a few months after birth because spontaneous regression can sometimes be observed.

Chest CT is very sensitive in assessing pulmonary damage in bronchopulmonary dysplasia (BPD) and radiological findings in BPD are well described. Validated CT scores are available to assess BPD, as available in other pulmonary diseases such as cystic fibrosis.To investigate whether there is a correlation between radiological pulmonary lesions and relevant BPD clinical data (gestational age, type and duration of mechanical ventilation, and severity of BPD) and assess the usefulness of a CT score in evaluating clinical severity.Retrospective study of 19 premature infants with BPD born between 1998 and 2007 who underwent at least one chest CT during their first year of life. A total of 29 CT were blindly evaluated by two radiologists for the presence or absence of pulmonary parenchymal abnormalities described in BPD (areas of decreased attenuation, presence of bullae/emphysema, bronchial wall thickening, bronchiectasis, linear, and subpleural opacities). This score was then compared with the most relevant clinical data.All CT scans showed abnormalities. The most frequent lesion was bronchial wall thickening observed in all patients, followed by linear (89.5%) and subpleural (89.5%) opacities. Areas of decreased attenuation were found in 68.4%. Bullae/emphysema and bronchiectasis were the less frequent item described (26.3% and 21.1%, respectively). The presence of areas of decreased attenuation significantly correlated with BPD severity (P = 0.03). However, there was no significant correlation between the CT score and clinical data.This study demonstrates the potential usefulness of chest CT score to assess the severity of BPD. Areas of decreased attenuation seem the most sensitive item to predict BPD severity. More patients are needed to validate this approach and to evaluate the long-term usefulness of CT scan.

Resume Introduction L’amelioration de la qualite des soins perinatals a permis d’augmenter la survie des nouveau-nes. Toutefois, les soins intensifs sont source de stimulations nociceptives qui pourraient avoir a long terme un impact negatif sur le developpement neurocomportemental. Aussi, offrir des soins de soutien au developpement durant la periode de plasticite cerebrale maximale, aurait des effets benefiques. Le but de cette etude etait le developpement et la validation d’un outil d’observation du comportement du nouveau-ne, a l’intention du personnel soignant. Methode Une grille d’observation comportementale integrant 45 variables dans 6 domaines du comportement sensorimoteur a ete validee en deux temps a l’aide de sequences video de nouveau-nes entre 25–37 semaines. Le coefficient de correlation intra-classe sur 65 evaluations a permis de simplifier l’outil a 23 variables avant l’analyse de validite et de fiabilite. Resultats Pour les 23 variables, la fiabilite entre observateurs etait faible pour 7 (coefficient de correlation intra-classe [CCI] 0,5). L’accord entre observateurs novices et experts variait entre 46,7 % et 98,7 %. Vingt variables avaient un niveau d’accord superieur a 60 %. Conclusion Cette etude de validation d’un outil d’evaluation du comportement sensorimoteur du nouveau-ne a permis d’identifier les variables pertinentes permettant une observation structuree et realisable par les soignants.

Non-invasive methods, including stable isotope techniques, indirect calorimetry, nutritional balance and skinfold thickness, have given a new insight into early postnatal growth in neonates. Neonates and premature infants in particular, create an unusual opportunity to study the fluid and metabolic adaptation to extrauterine life because their physical environment can be controlled, fluid and energy balance can be measured and the link between metabolism and the energetics of their postnatal growth can be assessed accurately. Thus the postnatal time course of total body water, heat production, energy cost of growth and composition of weight gain have been quantified in a series of "healthy" low-birth-weight premature infants. These results show that total body water is remarkably stable between postnatal days 3-21. Energy expenditure and heat production rates increase postnatally from mean values of 40 kcal/kg/day during the first week to 60 kcal/kg/day in the third week. An apparent energy balance deficit of 180 kcal/kg can be ascribed to premature delivery. The cost of protein metabolism is the highest energy demanding process related to growth. The fact that nitrogen balance becomes positive within 72 h after birth places the newborn in a transitional situation of dissociated balance between energy and protein metabolism during early postnatal growth: skinfold thickness, dry body mass and fat decrease, while there is a gain in protein and increase in supine length. This particular situation ends during the second postnatal week and soon thereafter the rate of weight gain matches statural growth. The goals of the following review are to summarize data on total body water and energy metabolism in premature infants and to discuss how they correlate with physiological aspects of early postnatal growth.

Summary OBJECTIVE: To provide population-based, gestational age (GA) stratified incidence of mortality and morbidities. METHODS: Population-based prospective observational study of infants born between 23 0/7 and 31 6/7 weeks GA in the years 2000–2004 in all Swiss neonatal intensive care units. Outcomes measured were: mortality, severe intraventricular haemorrhage (IVH), periventricular leukomalacia (PVL), necrotizing enterocolitis (NEC), moderate/ severe bronchopulmonary dysplasia (BPD) and free of major complications. RESULTS: Mortality was 19% of 3083 infants. Mortality (95% CI) decreased from 95% (88%, 99%) at 23 weeks to 3% (2%, 5%) at 31 weeks. Short-term survival free of major complications was 66% (65%, 68%) overall and increased from 2%(0%, 9%) to 89% (87%, 92%). Rate of IVH was 8% (7%, 9%), PVL 2% (2%, 3%), NEC 3% (3%, 4%) and BPD 11% (10%, 12%). Males had more IVH than females (9% vs. 6%). Antenatal steroids were associated with lower mortality (11% vs. 18%) and IVH (5% vs. 12%). Odds of free of major complications (OR, 95%CI) were positive for female gender 1.2 (1.0, 1.5), steroids 1.3 (1.1, 1.5), multiple gestation 1.3 (1.0, 1.6), not small for gestational age 2.7 (2.0, 3.5), and each additional week of GA 1.6 (1.5, 1.7). CONCLUSION: Mortality and incidence of morbidities known to influence outcome show a weekly decline with increasing gestational age, except for PVL. Gestational age stratified data are a key component for prenatal counselling.

Aim: Aplasia cutis congenita (ACC) has been observed after fetal exposure to the antithyroid drug methimazole (MMI), but not reported after propylthiouracil (PTU), the current antithyroid drug of choice during pregnancy. This occurrence has implications for patient information and causal research. Case report: We describe a surviving term co-twin to a mother with hyperthyroidism exposed to PTU from conception to 34 weeks of gestation presenting with ACC at birth. Discussion: The association between PTU exposure and ACC is clinically relevant and allows speculation on the etiology. A similar mechanism to the classical MMI-induced ACC is postulated, unless a vascular etiology suggested by a vanishing twin or maternal hyperthyroidism itself is causal. Coincidence of PTU exposure and ACC seems unlikely. Conclusion: ACC in a newborn after PTU exposure during pregnancy hitherto observed only after MMI strongly encourages further reports of similar cases that may remain clinically underdiagnosed or unreported. Such confirmation could have significant implications for maternal treatment of hyperthyroidism, common in women of childbearing age

Objective.To monitor trends in central line-associated bloodstream infections and clinical sepsis (CLABICS) among neonates and to determine risk factors for infection, especially dwell time.Design.Prospective, single-center cohort study conducted from 2001 through 2008.Setting.University-affiliated tertiary care center.Methods.Individualized surveillance of catheter use and CLABICS episodes was conducted. Data were obtained via regular on-site visits made 3 times a week. Trends over time were estimated by Poisson regression, and risk factor analysis was conducted using a Cox proportional hazards model and logistic regression.Results.In all, 1,124 neonates were exposed to 2,210 central lines for a total of 12,746 catheter-days and 11,467 catheter-days at risk. The median duration of catheter use was 8 (interquartile range, 5–11) days for peripherally inserted central catheters (PICCs) and 4 (interquartile range, 2-6) days for umbilical catheters; 102 CLABICS episodes were detected. The median time to infection was 7 days. Incidence densities were 8.5 CLABICS episodes per 1,000 catheter-days at risk and 8.0 CLABICS episodes per 1,000 catheter-days. The highest rates were identified among neonates weighing 750 g or lower (14.9 CLABICS episodes per 1,000 catheter days at risk) and for PICCs (13.2 CLABICS episodes per 1,000 catheter days at risk). Catheter dwell time was associated with CLABICS for all umbilical catheters (odds ratio [OR], 1.2 per day of use [95% confidence interval {CI}, 1.1–1.3] P< .001) and for PICCs for up to 7 days (OR, 1.2 [95% CI, 1.1–1.4]; P = .041), but not thereafter (OR, 1.0 [95% CI, 0.9–1.1]; P = .90).Conclusion.Catheter dwell time is a risk factor for CLABICS during the first 7 days, irrespective of catheter type. After 7 days, PICCs are less likely to become infected.

Neonatal resuscitation is one of the most cost-effective medical interventions, most often an emergency procedure involving a multidisciplinary team in the delivery room: doctors, nurses, midwives, obstetricians, anesthetists and other theatre staff. The success of resuscitation depends not only on individual competence but also on efficient teamwork between healthcare professionals in the delivery room; failure often results from the weakest link. Initiation of basic resuscitation procedures must be rapid and effective. Simple procedures must therefore be known by a large number of healthcare professionals, in fact all those potentially present at a delivery. Many complex neonatal diseases on the other hand are too infrequent for all to acquire sufficient personal experience. In addition, synchronization between the interventions of the different members in a perinatal team is complex. It is therefore necessary to train both individuals and teams to better manage perinatal crisis situations. The educational approach should remain multimodal, combining teaching of technical and non-techniques skills. Simulation of resuscitation scenarios can mimic emergency situations without any risk to the patient. It can be used for teaching and/or evaluation of the effectiveness of procedures and collaboration between actors. For maximum performance in complex pathologies, multidisciplinary teaching sessions are necessary. Simulation techniques adapted to neonatal resuscitation in the delivery room appear of great educational interest and proof of their efficiency gradually appears in literature.

Few data exist on time trends of antibiotic consumption among neonates.To assess secular trends in antibiotic consumption in the context of an antibiotic policy and the effect of antibiotic use on the development of antimicrobial resistance and outcome among neonates in a single center.We performed a prospective cohort study between 2001 and 2008 to monitor antibiotic consumption among neonates. In parallel, we initiated a policy to shorten antibiotic therapy for clinical sepsis and for infections caused by coagulase-negative staphylococci and to discontinue preemptive treatment when blood cultures were negative. Time trend analyses for antibiotic use and mortality were performed.In total, 1096 of 4075 neonates (26.7%) received 1281 courses of antibiotic treatment. Overall, days of therapy were 360 per 1000 patient-days. Days of therapy per 1000 patient-days decreased yearly by 2.8% (P0.001). Antibiotic-days to treat infections decreased yearly by 6.5% (P = 0.01) while antibiotic-days for preemptive treatment increased by 3.4% per year (P = 0.03). Mean treatment duration for confirmed infections decreased by 2.9% per year (P0.001). No significant upward trend was observed for infection-associated mortality. Of 271 detected healthcare-associated infections, 156 (57.6%) were microbiologically documented. The most frequent pathogens were coagulase-negative staphylococci (48.5%) followed by Escherichia coli (13.5%) and enterococci (9.4%). Rates for extended-spectrum beta-lactamase-producing microorganisms and methicillin-resistant Staphylococcus aureus remained low.Shortening antibiotic therapy and reducing preemptive treatment resulted in a moderate reduction of antibiotic use in the neonatal intensive care unit and did not increase mortality.

The ex utero intrapartum treatment (EXIT) procedure is designed to guarantee sufficient oxygenation for a foetus at risk of airway obstruction. This is achieved by improving lung ventilation, usually by establishing an airway during caesarean delivery whilst preserving the foetal-placental circulation temporarily. Indications for the EXIT procedure have extended from its original use in reversing iatrogenic tracheal obstruction in congenital diaphragmatic hernia to naturally occurring upper airway obstructions. We report our experience with a new and rarely mentioned indication for the EXIT procedure, intra-thoracic volume expansions. The elaboration of lowest risk scenarios through balancing risks with alternative options, foetal or neonatal intervention and coordination between professionals from various disciplines are the most important conditions for a successful EXIT procedure. The EXIT procedure requires a caesarean section that specifically differs from the traditional caesarean section during which uterine tone is maintained to minimize maternal bleeding. To guarantee foetal oxygenation during the EXIT procedure, profound uterine relaxation is desired. To gain time with optimal placental oxygenation in order to safely perform an airway intervention in a baby at risk of hypoxia may require deep inhalation anaesthesia and/or tocolytic agents. We review the EXIT procedure and present a case series from the University Hospital of Geneva that contrasts with the common indication for the EXIT procedure usually based on upper airway obstruction by its exclusive indication for intra-thoracic malformations/diseases.

OBJECTIVES. Hand hygiene promotion interventions rarely result in sustained improvement, and an assessment of their impact on individual infection risk has been lacking. We sought to measure the impact of hand hygiene promotion on health care worker compliance and health care–associated infection risk among neonates.METHODS. We conducted an intervention study with a 9-month follow-up among all of the health care workers at the neonatal unit of the Children's Hospital, University of Geneva Hospitals, between March 2001 and February 2004. A multifaceted hand hygiene education program was introduced with compliance assessed during successive observational surveys. Health care–associated infections were prospectively monitored, and genotypic relatedness of bloodstream pathogens was assessed by pulsed-field gel electrophoresis. A comparison of observed hand hygiene compliance and infection rates before, during, and after the intervention was conducted.RESULTS. A total of 5325 opportunities for hand hygiene were observed. Overall compliance improved gradually from 42% to 55% across study phases. This trend remained significant after adjustment for possible confounders and paralleled the measured increase in hand-rub consumption (from 66.6 to 89.2 L per 1000 patient-days). A 9-month follow-up survey showed sustained improvement in compliance (54%), notably with direct patient contact (49% at baseline vs 64% at follow-up). Improved compliance was independently associated with infection risk reduction among very low birth weight neonates. Bacteremia caused by clonally related pathogens markedly decreased after the intervention.CONCLUSIONS. Hand hygiene promotion, guided by health care workers' perceptions, identification of the dynamics of bacterial contamination of health care workers' hands, and performance feedback, is effective in sustaining compliance improvement and is independently associated with infection risk reduction among high-risk neonates.

Objective To investigate the safety and short term outcome of high dose recombinant human erythropoietin (rhEpo) given shortly after birth and subsequently over the first 2 days for neuroprotection to very preterm infants. Study design Randomized, double masked phase II trial. Preterm infants (gestational age 26 0/7-31 6/7 weeks) were given rhEpo (n t = 229; 3000 U/kg body weight) or NaCl 0.9% (n c = 214) intravenously at 3, 12-18, and 36-42 hours after birth. Results There were no relevant differences between the groups for short-term outcomes such as mortality, retinopathy of prematurity, intraventricular hemorrhage, sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia. At day 7-10, we found significantly higher hematocrit values, reticulocyte, and white blood cell counts, and a lower platelet count in the rhEpo group. Conclusions Early high-dose rhEpo administration to very premature infants is safe and causes no excess in mortality or major adverse events. Trial registration ClinicalTrials.gov: NCT00413946.

How do actual aspects of forgoing life supporting therapy (LST) in newborn infants compare with national ethical directives in a Swiss intensive care unit?A prospective set of data on deaths after forgoing LST over a three year period in a single intensive care unit is analysed in view of the directives issued by the Swiss Academy for Medical Sciences (SAMS).Thirty-four newborn infants died after a decision to forgo LST, 21 after withdrawing and 13 after withholding. The decision making process was confined to the caregivers' team. Parents rarely initiated the discussion but participated in all decisions and were considered as willing in 32% and consenting in 68%. Futility was invoked in 79% of cases and poor developmental outcome in 21%. Respiratory support was forgone in 59%, circulatory support in 6% and both in 35%. The mother assisted the child at the time of death in 91%. At that time, 82% of infants were receiving opiates and 18% benzodiazepines, some in a higher than usual dose. Death occurred at a median of 13 (25-75% = 6-25) minutes after withdrawing LST and 70 (27.5-147.5) after withholding (p0.001) without correlation with the dose of analgesic or sedative administered. None of these observations obviously departed from the Swiss ethical directives.Practices surrounding forgoing LST in newborn infants in a Swiss intensive care unit match ethical directives. Factors leading to occasional use of unusually high dose of analgesic and sedative drugs remain to be identified.

Objective To evaluate the safety of diphtheria–tetanus–acellular pertussis–inactivated polio– Haemophilus influenzae type B (DTaP-IPV-HIB) immunization in premature infants. Study design Observational study of 78 very low birth weight premature infants (mean gestational age, 28±2 weeks; mean birth weight, 1045±357 g) given DTaP-IPV-HIB vaccine before hospital discharge. Apnea, bradycardia, oxygen requirements and saturation, feeding practice, and medical interventions were assessed before and after immunization. The results were analyzed by the severity of the clinical condition and the persistence of prematurity-associated symptoms. Results Administration of DTaP-IPV-HIB elicited resurgence or increase in cardiorespiratory events in 47% of infants (15% had apnea, 21% had bradycardia, 42% of desaturations). Most vaccine-triggered events resolved spontaneously or after brief stimulation. The relative risk was 5- to 8-fold higher in infants with a severe clinical course or persistence of cardiorespiratory symptoms at the time of immunization. Bag-mask respiratory support was given to 5 of 78 infants, and O 2 requirements increased transiently in 4 of 21 infants with chronic lung disease, none requiring reventilation. Reintroduction of O 2 supplementation, interruption of active oral feeding, or postponing of hospital discharge was not required. Conclusions Cardiorespiratory events were frequently increased after DTaP-IPV-HIB immunization, requiring monitoring and appropriate intervention. However, these episodes did not have detrimental impact on the infants' clinical course. Timely immunization is warranted even in the most vulnerable preterm infants.

Ex utero intrapartum treatment (EXIT) of a fetus with severe bilateral hydrothorax is described. EXIT allows therapeutic interventions on the neonate while maintaining fetoplacental circulation. Thus it may be useful for fetuses presenting with severe pleural effusion towards the end of gestation and in whom in utero drainage is technically not possible or available and drainage post partum would result in profound and prolonged hypoxia until sufficient drainage of pleural fluid allowed lung expansion.

Background: Bacterial sepsis is a major threat in neonates born prematurely, and is associated with elevated morbidity and mortality. Little is known on the innate immune response to bacteria among extremely premature infants. Methodology/Principal Findings: We compared innate immune functions to bacteria commonly causing sepsis in 21 infants of less than 28 wks of gestational age, 24 infants born between 28 and 32 wks of gestational age, 25 term newborns and 20 healthy adults. Levels of surface expression of innate immune receptors (CD14, TLR2, TLR4, and MD-2) for Grampositive and Gram-negative bacteria were measured in cord blood leukocytes at the time of birth. The cytokine response to bacteria of those leukocytes as well as plasma-dependent opsonophagocytosis of bacteria by target leukocytes was also measured in the presence or absence of interferon-c. Leukocytes from extremely premature infants expressed very low levels of receptors important for bacterial recognition. Leukocyte inflammatory responses to bacteria and opsonophagocytic activity of plasma from premature infants were also severely impaired compared to term newborns or adults. These innate immune defects could be corrected when blood from premature infants was incubated ex vivo 12 hrs with interferon-c. Conclusion/Significance: Premature infants display markedly impaired innate immune functions, which likely account for their propensity to develop bacterial sepsis during the neonatal period. The fetal innate immune response progressively matures in the last three months in utero. Ex vivo treatment of leukocytes from premature neonates with interferon-c reversed their innate immune responses deficiency to bacteria. These data represent a promising proof-of-concept to treat premature newborns at the time of delivery with pharmacological agents aimed at maturing innate immune responses in order to prevent neonatal sepsis.

OBJECTIVE: Nasal continuous positive airway pressure (nCPAP) has been shown to improve the outcome of infants with respiratory distress syndrome. However, noise generation could be of concern. Therefore, our study was designed to measure the noise levels of various CPAP drivers. DESIGN: For infants admitted to our neonatal intensive care unit and paediatric critical care unit, we measured the noise level in the oral cavity, using a microphonic probe with a flexible capillary tube. Various CPAP drivers and interfaces have been tested. RESULTS: 27 measurements were made in eight infants. Mean noise level was 88.6 (SD 18.8) dB and was correlated with flow (p

We discuss the case of a newborn boy presenting well into term with severe bradycardic events and sinus pauses up to 5.4 sec. Sinus bradycardia below 80 bpm and sinus pauses or asystole of more than 2 sec are considered pathologic at term. After exclusion of specific causes, the diagnosis of vagal hyper-reflectivity (VHR) was retained, a state caused by unbalance between sympathetic and parasympathetic activity, the latter overriding the former. It is thought to be a functional and transitional anomaly of the sympathetic and vagal tone during the first months of life and may lead to prolonged monitoring and delayed hospital discharge. This form of rare bradycardia can be treated with atropine and allowed in our case immediate resolution of events and safe discharge from hospital. CONCLUSION: When VHR is diagnosed, atropine is the treatment permitting resolution of symptomatic episodes of bradycardia and early and safe discharge from hospital.
