Reporting interhospital neonatal intensive care transport: international five-step Delphi-based template.

OBJECTIVE: To develop a general and internationally applicable template of data variables for reporting interhospital neonatal intensive care transports. DESIGN: A five-step Delphi method. SETTING: A group of experts was guided through a formal consensus process using email. SUBJECTS: 12 experts in neonatal intensive care transports from Canada, Denmark, Norway, the UK and the USA. Four women and eight men. The experts were neonatologists, anaesthesiologists, intensive care nurse, anaesthetic nurse, medical leaders, researchers and a parent representative. MAIN OUTCOME MEASURES: 37 data variables were included in the final template. RESULTS: Consensus was achieved on a template of 37 data variables with definitions. 30 variables to be registered for each transport and 7 for annual registration of the system of the transport service. 11 data variables under the category structure, 20 under process and 6 under outcome. CONCLUSIONS: We developed a template with a set of data variables to be registered for neonatal intensive care transports. To register the same data will enable larger datasets and comparing services.

Variation in antibiotic consumption in very preterm infants-a 10 year population-based study.

OBJECTIVES: Wide variations in antibiotic use in very preterm infants have been reported across centres despite similar rates of infection. We describe 10 year trends in use of antibiotics and regional variations among very preterm infants in Norway. PATIENTS AND METHODS: All live-born very preterm infants (<32 weeks gestation) admitted to any neonatal unit in Norway during 2009-18 were included. Main outcomes were antibiotic consumption expressed as days of antibiotic therapy (DOT) per 1000 patient days (PD), regional variations in use across four health regions, rates of sepsis and sepsis-attributable mortality and trends of antibiotic use during the study period. RESULTS: We included 5296 infants: 3646 (69%) were born at 28-31 weeks and 1650 (31%) were born before 28 weeks gestation with similar background characteristics across the four health regions. Overall, 80% of the very preterm infants received antibiotic therapy. The most commonly prescribed antibiotics were the combination of narrow-spectrum ß-lactams and aminoglycosides, but between 2009 and 2018 we observed a marked reduction in their use from 100 to 40 DOT per 1000 PD (P < 0.001). In contrast, consumption of broad-spectrum ß-lactams remained unchanged (P = 0.308). There were large variations in consumption of vancomycin, broad-spectrum ß-lactams and first-generation cephalosporins, but no differences in sepsis-attributable mortality across regions. CONCLUSIONS: The overall antibiotic consumption was reduced during the study period. Marked regional variations remained in consumption of broad-spectrum ß-lactams and vancomycin, without association to sepsis-attributable mortality. Our results highlight the need for antibiotic stewardship strategies to reduce consumption of antibiotics that may enhance antibiotic resistance development.

Late-onset sepsis in very preterm infants in Norway in 2009-2018: a population-based study.

OBJECTIVE: To evaluate epidemiology and outcomes among very preterm infants (<32 weeks' gestation) with culture-positive and culture-negative late-onset sepsis (LOS). DESIGN: Cohort study using a nationwide, population-based registry. SETTING: 21 neonatal units in Norway. PARTICIPANTS: All very preterm infants born 1 January 2009-31 December 2018 and admitted to a neonatal unit. MAIN OUTCOME MEASURES: Incidences, pathogen distribution, LOS-attributable mortality and associated morbidity at discharge. RESULTS: Among 5296 very preterm infants, we identified 582 culture-positive LOS episodes in 493 infants (incidence 9.3%) and 282 culture-negative LOS episodes in 282 infants (incidence 5.3%). Extremely preterm infants (<28 weeks' gestation) had highest incidences of culture-positive (21.6%) and culture-negative (11.1%) LOS. The major causative pathogens were coagulase-negative staphylococci (49%), Staphylococcus aureus (15%), group B streptococci (10%) and Escherichia coli (8%). We observed increased odds of severe bronchopulmonary dysplasia (BPD) associated with both culture-positive (adjusted OR (aOR) 1.7; 95% CI 1.3 to 2.2) and culture-negative (aOR 1.6; 95% CI 1.3 to 2.6) LOS. Only culture-positive LOS was associated with increased odds of cystic periventricular leukomalacia (cPVL) (aOR 2.2; 95% CI 1.4 to 3.4) and severe retinopathy of prematurity (ROP) (aOR 1.8; 95% CI 1.2 to 2.8). Culture-positive LOS-attributable mortality was 6.3%, higher in Gram-negative (15.8%) compared with Gram-positive (4.1%) LOS, p=0.009. Among extremely preterm infants, survival rates increased from 75.2% in 2009-2013 to 81.0% in 2014-2018, p=0.005. In the same period culture-positive LOS rates increased from 17.1% to 25.6%, p<0.001. CONCLUSIONS: LOS contributes to a significant burden of disease in very preterm infants and is associated with increased odds of severe BPD, cPVL and severe ROP.

Delivery room handling of the newborn.

For newly born babies, especially those in need of intervention at birth, actions taken during the first minute after birth, the so-called "Golden Minute", can have important implications for long-term outcomes. Both delivery room handling, including identification of maternal and infant risk factors and provision of effective resuscitation interventions, and antenatal care decisions regarding antenatal steroid administration and mode of delivery, are important and can affect outcomes. Anticipating risk factors for neonates at high risk of requiring resuscitation can decrease time to resuscitation and improve the prognosis. Following a review of maternal and fetal risk factors affecting newborn resuscitation, we summarize the current recommendations for delivery room handling of the newborn. This includes recommendations and rationale for the use of delayed cord clamping and cord milking, heart rate assessment [including the use of electrocardiogram (ECG) electrodes in the delivery room], role of suctioning in newborn resuscitation, and the impact of various ventilatory modes. Oxygenation should be monitored by pulse oximetry. Effects of oxygen and surfactant on subsequent pulmonary outcomes, and recommendations for provisions of appropriate thermoregulatory support are discussed. Regular teaching of delivery room handling should be mandatory.

Live born recipient of twin-twin transfusion syndrome with anomalous mitral arcade.

We present a case report of anomalous mitral arcade in a live born former recipient of twin-twin transfusion syndrome. At 33+0 week of gestation fetal ultrasound demonstrated that she had a large mitral insufficiency, decreased movement of the lateral cusp of the mitral valve and dilated left atrium. The twins were delivered by caesarean section at week 33+1 due to fetal distress. The former recipient twin developed decompensated heart failure during her first day of life and was transferred to a surgical paediatric heart centre. Her clinical condition rapidly deteriorated, and she died of congestive heart failure 3 days old. Prenatal signs of anomalous mitral arcade in a recipient of twin-twin transfusion syndrome should warrant preparation of a critically ill neonate, including parental counselling and in utero transfer to surgical paediatric heart centre. There is a surgical treatment option available for neonates, but the experience with this technique is still very limited with a high risk of morbidity and mortality.

Inotropic Therapy in Newborns, A Population-Based National Registry Study.

OBJECTIVE: To describe the use of inotropic drugs and the characteristics of neonates receiving such treatment in a national cohort of patients admitted to neonatal ICUs in Norway. DESIGN: A national registry study of patients included in the Norwegian Neonatal Network database 2009-2014. Demographic and treatment data, including the use of inotropic drugs (dopamine, dobutamine, epinephrine, norepinephrine, milrinone, and levosimendan) and outcomes, were retrieved and analyzed. SETTING: Neonatal ICUs in Norway. PATIENTS: All patients admitted to Norwegian neonatal ICUs 2009-2014 with a postmenstrual age of less than 310 days at admission, corresponding to a postnatal age of less than 28 days for a child born at term (n = 36 397). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Inotropic drugs were administered to 974 of 361,803 live born infants (0.27%) in the study period, representing 2.7% of the neonatal ICU patient population. The relative proportion of neonatal ICU patients receiving inotropes decreased with increasing gestational age, yet 41% of the patients receiving inotropes were born at term. Of note, 89.8% of treated patients received dopamine. Use of inotropes was particularly prevalent in patients with necrotizing enterocolitis (72.4%) and pulmonary hypertension (42.1%) and in patients with gestational age less than 28 weeks (28.2%). Inotropic treatment initiated in the first week of life (84.2%) was associated with birth asphyxia and pulmonary hypertension, whereas treatment initiated after the first week of life was associated with extremely preterm birth, neonatal surgery, neonatal sepsis, cardiac disease, and necrotizing enterocolitis. CONCLUSIONS: This comprehensive epidemiologic study indicates that less than 0.3% of newborns receive inotropic support in the neonatal period. Dopamine was the most commonly used drug. Relating inotrope use to clinical condition, gestational age, and postnatal age may be useful for clinicians and helpful in delineating relevant patient populations for future clinical trials.

Eoxins: a new inflammatory pathway in childhood asthma.

BACKGROUND: Increased levels of leukotrienes (LTs) in exhaled breath condensate (EBC) are associated with asthma and bronchial hyperresponsiveness (BHR), whereas eicosanoids generated through the 15-lipoxygenase (LO) pathway (15-hydroxyeicosatetraenoic acid [HETE] and eoxins) have been less studied. OBJECTIVE: We investigated whether metabolites of the 5- and 15-LO pathways in EBC are associated with childhood asthma, asthma severity, and clinical parameters. METHODS: The present study included 131 school-aged children (27 children with problematic severe asthma, 80 children with mild-to-moderate asthma, and 24 healthy children) from the Severe Asthma Recognized in Childhood study and 19 children with other nonasthmatic chronic lung diseases. Clinical work-up included spirometry, fractional exhaled nitric oxide measurements, skin prick testing, and methacholine challenge. Eicosanoids were analyzed in EBC by using mass spectrometry and are reported as concentrations (in picograms per milliliter) and eicosanoid/palmitic acid (PA) ratios. RESULTS: Eoxin C4/PA, eoxin D4/PA, eoxin E4/PA, 15-HETE/PA, and LTC4/PA ratios were significantly increased in asthmatic versus healthy children. Eoxin D4/PA and LTE4/PA ratios were also significantly higher in children with BHR. A nonsignificant trend was observed toward higher eoxin/PA ratios with increasing asthma severity. In contrast to asthma, children with chronic lung disease had the highest 15-HETE/PA, LTC4/PA, LTE4/PA, and LTB4/PA ratios. CONCLUSION: The results point to increased activity of the 15-LO inflammatory pathway in childhood asthma. Mass spectrometric analyses of EBC demonstrate that increased eoxin levels not only accompany the increased 5-LO product LTC4 but are also associated with BHR. These markers might represent a new therapeutic target for asthma treatment.
