AbstractStudies in preterm infants have shown an association between late-onset sepsis (LOS) and the development of bronchopulmonary dysplasia (BPD). It is unknown whether clinical or biochemical characteristics during sepsis modulate the risk for BPD. This single-center retrospective cohort study included all patients with a gestational age < 30 weeks, born between 2009 and 2015, in whom empiric antimicrobial treatment was initiated > 72 h after birth and continued for at least 5 days, independent on microbiological results. The association between clinical and biochemical characteristics of LOS and the development of BPD in survivors were assessed with multivariate logistic regression analysis adjusted for early-onset sepsis, small for gestational age, and gestational age. Of the 756 admitted infants, 256 infants (mean GA: 27.0 weeks; birthweight: 924 grams) had at least one LOS episode, of whom 79 (30.9%) developed BPD. Analyses showed that only the need for and duration of mechanical ventilation during LOS were independently associated with an increased risk for BPD (adjusted OR 2.62, 95% CI 1.38, 4.96, p value 0.003, and OR 1.004, 95% CI 1.00, 1.007, p value 0.045, respectively).Conclusion: During a LOS, the need for and duration of mechanical ventilation are independently associated with the risk of developing BPD in preterm infants. What is Known:• Premature infants diagnosed with a late-onset sepsis are at higher risk of developing bronchopulmonary dysplasia• This association is mainly shown in infants with a positive blood culture What is New:• This study investigates the clinical and biochemical characteristics of late-onset sepsis and the development of bronchopulmonary dysplasia• The need for mechanical ventilation and duration of mechanical ventilation during late-onset sepsis are associated with an increased risk of developing bronchopulmonary dysplasia.

ObjectiveTo investigate the association between invasive mechanical ventilation (IMV) duration and long-term neurodevelopmental outcomes in preterm infants in an era of restricted IMV.DesignRetrospective cohort study.SettingSingle neonatal intensive care unit in Amsterdam.PatientsAll ventilated patients with a gestational age between 24 and 30 weeks born between 2010 and 2015.Main outcome measuresNeurodevelopmental impairment (NDI) at 24 months corrected age (CA). Data on patient characteristics, respiratory management, neonatal morbidities, mortality and bronchopulmonary dysplasia were collected. The relationship between IMV duration and NDI was determined by multivariate logistic regression analysis.ResultsDuring the study period, 368 admitted infants received IMV for a median duration of 2 days. Moderate and severe bronchopulmonary dysplasia was diagnosed in 33% of the infant. Multivariate regression analysis with adjustment for gestational age, small for gestational age and socioeconomic status showed a significant association between every day of IMV and NDI at 24 months CA (adjusted OR [aOR] 1.08, 95% CI 1.004 to 1.16, p=0.04). This association only reached borderline significance when also adjusting for severe neonatal morbidity (aOR 1.08, 95% CI 1.00 to 1.17, p=0.05).ConclusionEven in an era of restricted IMV, every additional day of IMV in preterm infants is strongly associated with an increased risk of NDI at 24 months CA. Limiting IMV should be an important focus in the treatment of preterm infants.

Extremely Low Gestational Age

Bronchopulmonary dysplasia (BPD) is one of the most frequent complications in extremely low gestational age neonates, but has remained largely unchanged in rate. We reviewed data on BPD prevention focusing on recent meta-analyses. Interventions with proven effectiveness in reducing BPD include the primary use of non-invasive respiratory support, the application of surfactant without endotracheal ventilation and the use of volume-targeted ventilation in infants requiring endotracheal intubation. Following extubation, synchronised nasal ventilation is more effective than continuous positive airway pressure in reducing BPD. Pharmacologically, commencing caffeine citrate on postnatal day 1 or 2 seems more effective than a later start. Applying intramuscular vitamin A for the first 4 weeks reduces BPD, but is expensive and painful and thus not widely used. Low-dose hydrocortisone for the first 10 days prevents BPD, but was associated with almost twice as many cases of late-onset sepsis in infants born at 24–25 weeks’ gestation. Inhaled corticosteroids, despite reducing BPD, were associated with a higher mortality rate. Administering dexamethasone to infants still requiring mechanical ventilation around postnatal weeks 2–3 may represent the best trade-off between restricting steroids to infants at risk of BPD while still affording high efficacy. Finally, identifying infants colonised with ureaplasma and treating those requiring intubation and mechanical ventilation with azithromycin is another promising approach to BPD prevention. Further interventions yet only backed by cohort studies include exclusive breastmilk feeding and a better prevention of nosocomial infections.

BACKGROUND: Early empiric antibiotic exposure appears to negatively influence feeding tolerance in preterm infants. However, the effect of prolonged antibiotic treatment is unknown. The objective of this study was to investigate whether prolonged antibiotics impact the time to full enteral feed in infants less than 29 weeks of gestational age with negative blood cultures. METHODS: Retrospective data for infants less than 29 weeks gestation age were retrieved from the PEARL-Peristat perinatal registry in Qatar. Exclusion criteria were major congenital anomalies, conditions requiring surgery in the first 10 days of life, positive blood cultures in the first 48 hours of life, and death within the first week of life. Antibiotic courses were categorized as prolonged if continued more than 48 hours. The primary outcome was the duration of total parenteral nutrition. RESULTS: Of 199 study infants, 185 (92.9%) underwent antibiotic treatment for >  48 hours despite negative blood cultures. The median duration of parenteral nutrition was not significantly different between the prolonged and short antibiotic groups (25 and 22 days, respectively; p = 0.139). Infants with prolonged antibiotic courses experienced non-significantly higher levels of necrotizing enterocolitis (7.1% and 18.4%, respectively), bronchopulmonary dysplasia (28.6% and 45.4%, respectively), and retinopathy of prematurity (14.3% and 38.4%, respectively). There were no differences in the late-onset sepsis rate (78.6% and 82.1%, respectively) and the in-hospital death rate (7.1% and 7.6%, respectively). CONCLUSIONS: Prolonged antibiotic treatment in infants less than 29 weeks gestation with negative blood cultures has no significant impact on the time to full enteral feed.

PurposeThe aim of this study was to assess morbidity and mortality pattern of small for gestational age (SGA) preterm infants in comparison to appropriate for gestational age (AGA) preterm infants of similar gestational age.MethodWe compared neonatal outcomes of 1336, 1:1 matched, singleton SGA and AGA preterm infants based on their gestational age using data from the study ‘Causes of Illness and Death of Preterm Infants in Ethiopia (SIP)’. Data were analysed using SPSS V.23. ORs and 95% CIs and χ2 tests were done, p value of <0.05 was considered statistically significant.ResultThe majority of the infants (1194, 89%) were moderate to late preterm (32–36 weeks of gestation), 763 (57%) were females. Male preterm infants had higher risk of being SGA than female infants (p<0.001). SGA infants had increased risk of hypoglycaemic (OR and 95% CI 1.6 (1.2 to 2.0), necrotising enterocolitis (NEC) 2.3 (1.2 to 4.1), polycythaemia 3.0 (1.6 to 5.4), late-onset neonatal sepsis (LOS) 3.6 (1.1 to 10.9)) and prolonged hospitalisation 2.9 (2.0 to 4.2). The rates of respiratory distress syndrome (RDS), apnoea and mortality were similar in the SGA and AGA groups.ConclusionNeonatal complications such as hypoglycaemic, NEC, LOS, polycythaemia and prolonged hospitalisation are more common in SGA infants, while rates of RDS and mortality are similar in SGA and AGA groups. Early recognition of SGA status, high index of suspicion and screening for complications associated and timely intervention to prevent complications need due consideration.

Abstract BackgroundOropharyngeal administration of colostrum (OAC) may provide immunoprotective and anti-inflammatory effects that potentially reduce the incidence of necrotizing enterocolitis (NEC) and late-onset sepsis (LOS) and improve short-term outcomes.ObjectiveTo evaluate the role of OAC in the early prevention of NEC and LOS in preterm infants with gestational age (GA) ≤ 32 weeks.MethodsA randomized, placebo-controlled trial was conducted in a 40-bed tertiary neonatal intensive care unit (NICU) in China. Preterm infants with GA ≤ 32 weeks were divided randomly into an OAC group, which received 0.4 ml maternal colostrum smearing via the oropharyngeal route every 3 hours for 10 days beginning within the first 48 hours after birth, and a control group, which received normal saline instead. Data from the two groups were collected and compared.ResultsA total of 127 patients in the OAC group and 125 patients in the control group were finally enrolled. The incidence of NEC (Bell stage 2 or 3) and LOS was lower in the OAC group [2.4% vs. 10.4%, χ2 = 6.845, ༰=0.009; 4.7% vs. 13.6%, χ2 = 5.983, ༰=0.014]. In addition, the incidence of intraventricular hemorrhage (IVH) (stage 3 or 4) was lower [1.6% vs. 7.2%,χ2 = 4.775, ༰=0.029], and the time of achieving full enteral feeding was shorter [ 22.0 days vs. 25.0 days༌Z = 6༌424.500༌P = 0.009)] in the OAC group. No cases of adverse reactions were observed in either group.ConclusionsOAC is a safe and simple NICU procedure that yields a potential advantage in decreasing the incidence of NEC, LOS, and severe IVH and shortening the time to achieve full enteral feeding in preterm infants with GA ≤ 32 weeks.Trial registrationChinese Clinical Trial Registry, ChiCTR1900023697, Registered 8 June 2019, Retrospectively registered, http://www.chictr.org.cn/edit.aspx? pid = 39398

Volatile Organic

Fecal volatile organic compounds (VOC) reflect human and gut microbiota metabolic pathways and their interaction. VOC behold potential as non-invasive preclinical diagnostic biomarkers in various diseases, e.g., necrotizing enterocolitis and late onset sepsis. There is a need for standardization and assessment of the influence of clinical and environmental factors on the VOC outcome before this technique can be applied in clinical practice. The aim of this study was to investigate the influence of gestational age (GA) and mode of delivery on the fecal VOC pattern in preterm infants born below 30 weeks of gestation. Longitudinal fecal samples, collected on days 7, 14, and 21 postnatally, were analyzed by an electronic nose device (Cyranose 320®). In total, 58 preterm infants were included (29 infants born at GA 24–26 weeks vs. 29 at 27–29 completed weeks, 24 vaginally born vs. 34 via C-section). No differences were identified at any predefined time point in terms of GA and delivery mode (p > 0.05). We, therefore, concluded that correction for these factors in this population is not warranted when performing fecal VOC analysis in the first three weeks of life.

Abstract Objective Survivors of extremely preterm birth are at risk of re-hospitalization but risk factors in the Canadian population are unknown. Our objective is to identify neonatal, sociodemographic, and geographic characteristics that predict re-hospitalization in Canadian extremely preterm neonates. Methods This is a retrospective analysis of a prospective observational cohort study that included preterm infants born 22 to 28 weeks’ gestational age from April 1, 2009 to September 30, 2011 and seen at 18 to 24 months corrected gestational age in a Canadian Neonatal Follow-Up Network clinic. Characteristics of infants re-hospitalized versus not re-hospitalized are compared. The potential neonatal, sociodemographic, and geographic factors with significant association in the univariate analysis are included in a multivariate model. Results From a total of 2,275 preterm infants born at 22 to 28 weeks gestation included, 838 (36.8%) were re-hospitalized at least once. There were significant disparities between Canadian provincial regions, ranging from 25.9% to 49.4%. In the multivariate logistic regression analysis, factors associated with an increased risk for re-hospitalization were region of residence, male sex, bronchopulmonary dysplasia, necrotizing enterocolitis, prolonged neonatal intensive care unit (NICU) stay, ethnicity, Indigenous ethnicity, and sibling(s) in the home. Conclusion Various neonatal, sociodemographic, and geographic factors predict re-hospitalization of extremely preterm infants born in Canada. The risk factors of re-hospitalization provide insights to help health care leaders explore potential preventative approaches to improve child health and reduce health care system costs.

Background and Objectives. Antacids are often prescribed to preterm infants due to misdiagnosis of gastro-oesophageal reflux. This suppresses gastric acidity, a major defence mechanism against infection. This study aims to determine if ranitidine and omeprazole use in very low birth weight (VLBW) neonates, <1500 grams, is associated with increased risk of late onset sepsis, necrotising enterocolitis (NEC), and mortality.Methods. Retrospective analysis was conducted on neonates, <1500 grams, born and admitted into theNeonatal Intensive Care UnitatThe Canberra Hospitalduring the period from January 2008 to December 2012. Information regarding late onset sepsis, NEC, mortality, ranitidine/omeprazole use, and other neonatal/hospital factors was collected for each neonate.Results. 360 neonates were evaluated, 64 received ranitidine and/or omeprazole, and 296 had not. There were no statistically significant differences in incidence of late onset sepsis (OR = 0.52, CI = 0.24–1.1, andp= 0.117), NEC Stage 2 and above (OR = 0.4, CI = 0.05–3.2, andp= 0.7), or mortality (OR = 0.35, CI = 0.08–1.5, andp= 0.19) between the two groups. After adjusting significant differences in neonatal and hospital factors, risk of late onset sepsis was significantly lower in those that received ranitidine/omeprazole (OR = 0.28, CI = 0.13–0.65, andp= 0.003).Conclusions. Ranitidine and omeprazole use in VLBW preterm infants may not be associated with an increased risk of infection, NEC, and mortality.
