Zhang M, Zhang W, Liao H. Efficacy and safety of different inhaled corticosteroids for bronchopulmonary dysplasia prevention in preterm infants: A systematic review and meta-analysis. Respir Med Res 2024; 85:101096. [PMID: 38744231 DOI: 10.1016/j.resmer.2024.101096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 07/13/2023] [Accepted: 02/25/2024] [Indexed: 05/16/2024]
Abstract
BACKGROUND This systematic review and meta-analysis aimed to evaluate the efficacy and safety of inhaled corticosteroids (budesonide, beclomethasone, or fluticasone propionate) in preventing bronchopulmonary dysplasia (BPD) for premature infants. METHOD Electronic databases, including PubMed, EMBASE, Web of science, Scopus, and Cochrane library, were searched from databases inception to January 2022 for eligible randomized controlled trials. Clinical outcomes such as BPD, mortality, BPD or death, adverse events, and neurodevelopmental outcomes were assessed. RESULTS Overall, budesonide was significantly associated with a reduction in BPD at 36 weeks' postmenstrual age (RR 0.48; 95 % CI [0.38, 0.62]) and patent ductus arteriosus (PDA) (RR 0.75; 95 % CI [0.63, 0.89]) compared with control treatments. Early longer duration inhalation of budesonide alone was associated with a lower risk of BPD at 36 weeks' postmenstrual age and PDA compared with controls. Early shorter duration intratracheal instillation of budesonide with surfactant as vehicle was associated with a lower risk of BPD at 36 weeks' postmenstrual age and all-cause mortality compared with surfactant. There was no statistically significant difference between budesonide and control groups regarding neurodevelopmental impairment. Beclomethasone and fluticasone propionate did not show any superior or inferior effect on clinical outcomes compared to control treatments. CONCLUSION These findings suggest that budesonide, especially intratracheal instillation of budesonide using surfactant as a vehicle, is a safe and effective option in preventing BPD for preterm infants. More well-design large-scale trials with long-term follow-ups are necessary to verify the present findings.

Abstract
OBJECTIVE Spontaneous intestinal perforation (SIP) occurs commonly in extremely low gestational age newborns (ELGANs; <30 weeks' GA). Early, concurrent neonatal use of indomethacin (Neo_IN) and hydrocortisone (Neo_HC) is a known risk for SIP. Mothers in premature labor often receive indomethacin (Mat_IN) for tocolysis and steroids (Mat_S) for fetal maturation. Coincidentally, ELGANs may receive Neo_IN or Neo_HC within the first week of life. There are limited data on the effect of combined exposures to maternal and neonatal medications. We hypothesized that proximity exposure to these medications may increase the risk of SIP. STUDY DESIGN We reviewed the medical records of ELGANs from June 2014 to December 2019 at a single level III neonatal intensive care unit. We compared antenatal and postnatal indomethacin and steroid use between neonates with and without SIP. For analysis, chi-square, Student's t-test, Fisher's exact test, and Mann-Whitney U tests were used. RESULTS Among 417 ELGANs, SIP was diagnosed in 23, predominantly in neonates < 26 weeks' GA (n = 21/126, 16.7%). Risk factors analysis focused on this GA cohort in which SIP was most prevalent. Mat_IN administration within 2 days of delivery increased SIP risk (odds ratio: 3; 95% confidence interval: 1.25-7.94; p = 0.036). Neo_HC was not independently associated with SIP (p = 0.38). A higher proportion of SIP group had close temporal exposure of Mat_IN and Neo_HC compared with the non-SIP group, though not statistically significant (14 vs. 7%, p = 0.24). CONCLUSION Peripartum Mat_IN was associated with increased risk for SIP in this small study sample. Larger studies are needed to further delineate SIP risk from the interaction of peripartum maternal medication with early postnatal therapies and disease pathophysiology. KEY POINTS · Perinatal indomethacin is associated with SIP in preterm infants born at less than 26 weeks.. · Temporal proximity of prenatal/postnatal medication exposure matters.. · Indomethacin and Hydrocortisone the risks, benefits, and timing related to SIP..

Interaction of hydrocortisone and illness severity on head growth in cohort of ELBW infants. Pediatr Res 2023; 94:1958-1965.

Abstract
BACKGROUND Extremely low birth weight (ELBW) infants comprise a fragile population at risk for neurodevelopmental disabilities (NDD). Systemic steroids were previously associated with NDD, but more recent studies suggest hydrocortisone (HCT) may improve survival without increasing NDD. However, the effects of HCT on head growth adjusted for illness severity during NICU hospitalization are unknown. Thus, we hypothesize that HCT will protect head growth, accounting for illness severity using a modified neonatal Sequential Organ Failure Assessment (M-nSOFA) score. METHODS We conducted a retrospective study that included infants born at 23-29 weeks gestational age (GA) and < 1000 g. Our study included 73 infants, 41% of whom received HCT. RESULTS We found negative correlations between growth parameters and age, similar between HCT and control patients. HCT-exposed infants had lower GA but similar normalized birth weights; HCT-exposed infants also had higher illness severity and longer lengths of hospital stay. We found an interaction between HCT exposure and illness severity on head growth, such that infants exposed to HCT had better head growth compared to those not exposed to HCT when adjusted for illness severity. CONCLUSION These findings emphasize the importance of considering patient illness severity and suggest that HCT use may offer additional benefits not previously considered. IMPACT This is the first study to assess the relationship between head growth and illness severity in extremely preterm infants with extremely low birth weights during their initial NICU hospitalization. Infants exposed to hydrocortisone (HCT) were overall more ill than those not exposed, yet HCT exposed infants had better preserved head growth relative to illness severity. Better understanding of the effects of HCT exposure on this vulnerable population will help guide more informed decisions on the relative risks and benefits for HCT use.

Abstract
As the frequency of viable low birth weight preterm babies increases, bronchopulmonary dysplasia (BPD), one of the most important morbidities in these babies, also increases. Using postnatal steroids to reduce the development of BPD has not been fully enlightened. Besides all prevention strategies for reducing the development of BPD, it is known that steroid therapy used in the 1st week of life could induce negative neuromotor development according to current data. It may be recommended to administer low-dose dexamethasone between 8 and 49 days in infants dependent on mechanical ventilators in the postnatal period. It is seen that the use of hydrocortisone in the early period does not cause negative neuromotor development, but it cannot prevent the development of BPD as much as dexamethasone. All intensive care units must have their steroid protocol for BPD and use steroids in cases when the BPD development scale score is >60-65% and should have a goal of trying to keep the cumulative dose at the lowest level.

Abstract
As survival of extremely preterm infants continues to improve, there is also an associated increase in bronchopulmonary dysplasia (BPD), one of the most significant complications of preterm birth. BPD development is multifactorial resulting from exposure to multiple antenatal and postnatal stressors. BPD has both short-term health implications and long-term sequelae including increased respiratory, cardiovascular, and neurological morbidity. Transforming growth factor β (TGF-β) is an important signaling pathway in lung development, organ injury, and fibrosis and is implicated in the development of BPD. This review provides a detailed account on the role of TGF-β in antenatal and postnatal lung development, the effect of known risk factors for BPD on the TGF-β signaling pathway, and how medications currently in use or under development, for the prevention or treatment of BPD, affect TGF-β signaling.

Abstract
Understanding the adsorption mechanism of corticosteroids in the lung surfactant requires the knowledge of corticosteroid molecular interactions with lung surfactant monolayer (LSM). We employed coarse-grained molecular dynamics simulation to explore the action of hydrocortisone on an LSM comprised of a phospholipid, cholesterol and surfactant protein. The structural and dynamical morphology of the lung surfactant monolayer at different surface tensions were investigated to assess the monolayer compressibility. The simulations were also conducted at the two extreme ends of breathing cycles: exhalation (0 mN m-1 surface tension) and inhalation (20 mN m-1 surface tension). The impact of surface tension and hydrocortisone concentration on the monolayer compressibility and stability are significant, resulting the monolayer expansion at higher surface tension. However, at low surface tension, the highly compressed monolayer induces monolayer instability in the presence of the drug due to the accumulation of surfactant protein and drug. The constant area per lipid simulation results demonstrate that the surface pressure-area isotherms show a decrease in area-per-lipid with increased drug concentration. The drug-induced expansion causes considerable instability in the monolayer after a specific drug concentration is attained at inhalation breathing condition, whereas, for exhalation breathing, the monolayer gets more compressed, causing the LSM to collapse. The monolayer collapse occurs for inhalation due to the higher drug concentration, whereas for exhalation due to the accumulation of surfactant proteins and drugs. The findings from this study will aid in enhancing the knowledge of molecular interactions of corticosteroid drugs with lung surfactants to treat respiratory diseases.

Abstract
OBJECTIVE The study aimed to evaluate the efficacy of dual medication therapy (DMT) with oral acetaminophen and oral ibuprofen for the closure of a hemodynamically significant patent ductus arteriosus (hsPDA). STUDY DESIGN In a prospective case-control cohort study (July 2017-May 2019), infants <29 weeks' gestational age and birth weight <1,000 g at ≤14 postnatal days with hsPDA and ratio of the smallest ductal diameter to the ostium of the left pulmonary artery diameter >0.5 were eligible. Infants received 10 mg/kg oral ibuprofen followed by two additional doses of 5 mg/kg at 24 and 48 hours after the initial ibuprofen dose and concomitant treatment with 15 mg/kg oral acetaminophen every 6 hours for 3 days (12 doses). Success of PDA treatment was defined as a small or absent PDA as ascertained by echocardiographic measurements. The p-values of comparisons were adjusted for multiple comparisons to preserve an error rate of 5%. RESULTS Overall, 20 infants received oral DMT and 11 infants received intravenous single medication therapy (SMT) with ibuprofen. The rates of successful PDA treatment following the first treatment in DMT and SMT groups were not statistically different (11/20 [55%] vs. 4/11 [36%], p = 0.46). However, DMT significantly decreased PDA size (mean difference = 0.54 mm, 95% confidence interval [CI]: 0.21-0.96, adjusted p-value = 0.0002) and PDA/LPA ratio (mean difference = 0.27, 95% CI: 0.10-0.47, adjusted p-value = 0.0004). We observed no evidence of hematologic, hepatic, or renal impairment. CONCLUSION DMT achieved a greater degree of PDA closure than SMT and did not result in abnormalities in hepatic and renal profile. KEY POINTS · No consensus on optimal medication for PDA treatment is available.. · Dual oral medication therapy (ibuprofen and acetaminophen) could be an effective alternative treatment for PDA.. · Dual oral medication therapy (ibuprofen and acetaminophen) may have a better safety profile than currently approved medications such as intravenous indomethacin and intravenous ibuprofen..

Abstract
Ventilation and respiratory care have substantially changed over the last decades in extremely premature neonates but the impact on respiratory health remains largely unclear. To determine changes in respiratory care and disease frequency in extremely premature infants, a retrospective single-centre cohort study of extremely preterm infants was performed. All infants born alive between 24 + 0 and 27 + 6 weeks of gestation in 2000-2001 (Epoch 1), 2009-2010 (Epoch 2), and 2018-2019 (Epoch 3) were included. The primary outcome of this study was the incidence of bronchopulmonary dysplasia (BPD, diagnosed according to three different criteria) or death. Secondary outcomes included the usage of different ventilation modes, changes in pharmacotherapy, and the incidence of significant extra-pulmonary morbidities. A total of 184 neonates were included of whom 151 survived until 36 weeks of corrected GA (cGA). Oxygen or positive pressure dependence increased over time (26.1%, 41.7%, and 56.1% respectively), with higher adjusted odds in Epoch 3 for the composite outcome "BPD or death" (adjusted odds ratio: 2.55 [95%CI 1.19-5.61]). Severity-based definitions showed increasing trends in survivors only. Time spent on invasive mechanical ventilation was similar throughout the years, but the use of non-invasive ventilation significantly increased in Epoch 3 (32.0 [95%CI 25.0-37.0] vs 27.0 [95%CI 26.0-32.0] vs 53.0 [95%CI 46.0-58.0] days). Moreover, mortality-adjusted rates of severe IVH, NEC, or intestinal perforation and multiple sepsis tended to decrease. Conclusion: In spite of significant clinical advancements and adherence to novel treatment guidelines in our neonatal intensive care unit, the incidence of BPD increased over time. What is Known: • Rates of BPD are stable or increase in population-based studies. • Extremely preterm infants are particularly susceptible to developing BPD. What is New: • Despite increased use of evidence-based corticosteroid administration and early initiation of caffeine, the incidence of BPD has not decreased over the past decade. • Increased usage of non-invasive ventilation is associated with an increase of BPD incidence.

Abstract
Antenatal corticosteroids undoubtedly save many lives and improve the quality of many others. However, the currently accepted dosage schedule has been in place since 1972, and recent studies have suggested that beneficial effects may be seen with less. Most but not all studies of long-term outcome show no adverse effects. The use of antenatal corticosteroids in women with COVID-19 raises important questions regarding potential risks and benefits. However, currently, most authorities recommend continuing according to published guidelines. With regard to postnatal corticosteroids, alternatives to systemic dexamethasone, the somewhat tainted standard of care, show promise in preventing bronchopulmonary dysplasia without adverse effects. Systemic hydrocortisone and inhaled corticosteroids are of note. The mixture of surfactant and corticosteroids deserves particular attention in the coming years.

Abstract
BACKGROUND Systemic hydrocortisone administration has been widely used in preterm infants who are at risk of bronchopulmonary dysplasia (BPD). However, the effects of hydrocortisone on cytokine profiles have not been examined. We aimed to investigate the effects of postnatal hydrocortisone treatment on serum cytokine levels in extremely preterm infants. METHODS This is a retrospective study of 29 extremely preterm infants born at <28 weeks of gestational age. We obtained serum from blood samples collected during an early phase (5-20 days) and a late phase (28-60 days) after birth. We measured the levels of proinflammatory cytokines (tumor necrosis factors α and β, interleukin (IL)-1β, and IL-6), T-helper (Th) 1 cytokines (interferon-γ, IL-2, and IL-12p70), Th2 cytokines (IL-4, IL-5, and IL-10), Th17 cytokine IL-17A, and chemokine IL-8. The cytokine levels between the early and late phases were compared between infants who received postnatal hydrocortisone and those who did not. RESULTS Thirteen infants (45%) received systemic hydrocortisone treatment at a median age of 15 days (IQR: 10.0-21.5) after birth due to respiratory deterioration. The percentage of BPD was higher in the steroid group than in the non-steroid group (P = 0.008). The ratio of IL-6 for the late-to-early phase was significantly lower in the steroid group than in the non-steroid group (P = 0.04). The concentration of the other cytokines remained unchanged between the phases. CONCLUSIONS Although the postnatal hydrocortisone treatment provided for respiratory deterioration did not prevent the BPD development, hydrocortisone treatment might suppress IL-6 overproduction in extremely preterm infants.

Abstract
BACKGROUND Impaired adrenal function is a well-described entity in critically ill term and preterm neonates with systemic hypotension. The standard treatment for neonatal hypotension includes volume expanders and vasopressors. Recent evidence supports the use of glucocorticoids for the primary or rescue treatment of neonatal hypotension associated with impaired adrenal function. However, inconsistency regarding the prescribed dosing regimen to provide the best balance between efficacy and safety in this vulnerable population remains an area of concern. METHODS We will conduct a systematic review and meta-analysis to evaluate low-dosing compared with high-dosing regimens of hydrocortisone for the treatment of hypotension in critically ill term, preterm and very low birth weight neonates. Ovid MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and Web of Science will be searched from inception to November 2021. Study screening and selection will be completed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Our primary outcomes will be (1) an improvement in end-organ perfusion, defined as an increase in blood pressure along with an increase in urine output or a reduction in serum lactate and (2) mortality prior to discharge. Our secondary outcomes will be the development of (1) major neurosensory abnormality, (2) bronchopulmonary dysplasia and (3) the occurrence of adverse events. DISCUSSION Hydrocortisone may be beneficial in the treatment of hypotension associated with impaired adrenal function among critically ill neonates. However, its optimal dosing to balance desired efficacy with the risk of adverse events is yet to be determined. Our systematic review and meta-analysis aims to address this evidence gap, providing valuable knowledge for a large audience, including guideline developers, policy-makers and clinicians. PROSPERO REGISTRATION NUMBER This protocol is submitted for registration to the international database of prospectively registered systematic reviews (PROSPERO, awaiting registration number).

[PMID: 34817668 DOI: 10.1007/s00408-021-00489-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 10/24/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects newborns who need oxygen therapy, and high-concentration oxygen therapy may cause neonatal morbidity and mortality in newborns. E26 oncogene homologue 1 (ETS1) and transglutaminase 2 (TGM2) have been reported to be associated with lung cell injury. However, the mechanism of ETS1 in regulating BPD is still unclear. METHODS Hyperoxia-induced A549 cells to simulate hyperoxia-induced alveolar epithelial cell injury. MTT assays and colony formation assays were performed to investigate the proliferation of A549 cells. Flow cytometry was carried out to quantify the apoptosis of A549 cells. The expression levels of ETS1 and TGM2 were quantified by qRT-PCR. The protein expression levels of ETS1, TGM2, β-catenin, c-Jun and MET were measured by western blot. Overexpression of ETS1, overexpression of TGM2, overexpression of ETS1 with downregulation of TGM2 and overexpression of TGM2 with inhibition of Wnt/β-catenin pathway were performed to investigate the role of ETS1, TGM2 and Wnt/β-catenin pathways in hyperoxia-induced alveolar epithelial cell injury. RESULTS Hyperoxia decreased the proliferation and promoted the apoptosis of cells in a time-dependent manner. Moreover, overexpression of ETS1 rescued the effect of hyperoxia on proliferation and apoptosis. In addition, overexpression of TGM2 participated in the regulation of hyperoxia-induced proliferation and apoptosis. ETS1 regulated hyperoxia-induced alveolar epithelial cell injury through the Wnt/β-catenin pathway via TGM2. CONCLUSION ETS1 ameliorates hyperoxia-induced alveolar epithelial cell injury through the TGM2-mediated Wnt/β-catenin pathway.

Lung Ultrasound for Prediction of Bronchopulmonary Dysplasia in Extreme Preterm Neonates: A Prospective Diagnostic Cohort Study. J Pediatr 2021; 238:187-192.e2. [PMID: 34237347 DOI: 10.1016/j.jpeds.2021.06.079] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/24/2021] [Accepted: 06/29/2021] [Indexed: 12/12/2022]
Abstract
OBJECTIVES To evaluate the diagnostic and predictive ability of lung ultrasound at 3 time points in the first 2 weeks after birth for predicting bronchopulmonary dysplasia (BPD) among infants <29 weeks of gestational age. STUDY DESIGN This was a prospective, diagnostic cohort study. Lung ultrasound was performed on days 3, 7, and 14 after birth and lung ultrasound scores (LUS) were calculated in blinded fashion. Diagnostic test characteristics and area under receiver operating characteristic (AUROC) curves were calculated. RESULTS A total of 152 infants were enrolled with mean (SD) gestational age of 25.8 (1.5) weeks gestation. Of them, 87 (57%) infants were diagnosed with BPD. The LUS were significantly higher in infants diagnosed with BPD compared with those without BPD at all scan time points (P < .01). The score of >10 at all 3 time points had higher sensitivity (0.89, 0.89, and 0.77), specificity (0.87, 0.90, and 0.92), and corresponding clinically important positive and negative likelihood ratios. The AUROC for LUS at the 3 time points were 0.96, 0.97, and 0.95 on day 3, 7, and 14, respectively. Compared with the model using clinical characteristics, LUS alone had higher AUROC (P < .05 for all 3 time points). CONCLUSIONS In this cohort, LUS in the first 2 weeks after birth had a very high predictive value for the diagnosis of BPD among infants of <29 weeks of gestation.

Duration of mechanical ventilation is more critical for brain growth than postnatal hydrocortisone in extremely preterm infants. Eur J Pediatr 2021; 180:3307-3315. [PMID: 33993400 DOI: 10.1007/s00431-021-04113-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/30/2021] [Accepted: 05/10/2021] [Indexed: 10/21/2022]
Abstract
Hydrocortisone is used in preterm infants. However, early disruption of growth velocities was observed in infants exposed to hydrocortisone. This retrospective study aimed to explore the postnatal brain growth of extremely preterm infants requiring hydrocortisone treatment as well as its association with perinatal factors. Extremely preterm infants exposed to hydrocortisone from 2011 to 2016 who survived up to 12 months were included. Each of them was matched with two infants not treated with hydrocortisone exhibiting similar gestational ages and nearly similar birth head circumferences. The outcome variables were brain tissue areas on MRIs performed at term-equivalent age and postnatal head circumference growth up to a corrected age of 12 months. Univariate and multiple regression analyses were performed. Infants treated with hydrocortisone (n=20) were matched with 40 infants not exposed to hydrocortisone. The infants exposed to hydrocortisone exhibited a lower birth weight (p=0.04) and a longer duration of mechanical ventilation (p<0.0001). Infants treated with hydrocortisone exhibited a smaller basal ganglia/thalamus area (p=0.04) at term-equivalent age and a smaller head circumference at a corrected age of 12 months (p=0.003). However, the basal ganglia/thalamus area and the postnatal brain growth were independently associated with the duration of mechanical ventilation and not with hydrocortisone. Interestingly, a significant interaction between hydrocortisone and sex was observed (p=0.04).Conclusion: This study supports previous data that indicated no obvious impact of hydrocortisone on brain growth and highlights the relationship between the severity of the neonatal course and postnatal brain growth in extremely preterm infants. What is Known: • Postnatal hydrocortisone disrupts transiently growth velocities including the head circumference growth. • Postnatal hydrocortisone has less impact on neurodevelopment than dexamethasone. What is New: • Hydrocortisone prescribed for infants in the most severe conditions did not show independent effect on brain growth up to the corrected age of 12 months. However, a different effect of hydrocortisone according to sex can't be excluded and needs further explorations. • Perinatal factors as birth weight and duration of mechanical ventilation were determinant for the subsequent brain growth.

Abstract
AIM In animal studies, aminoglycosides induced ductus arteriosus relaxation in a dose-dependent fashion. We tested the hypothesis that antibiotic treatment of preterm infants with aminoglycosides is associated with higher rates of surgical patent ductus arteriosus (PDA) closure. METHODS Preterm infants (birthweight <1000 grams or gestational age <29 weeks) enrolled in 62 German neonatal intensive care units (NICUs) were analysed. NICUs were stratified according to the use of aminoglycosides as first-line antibiotics. RESULTS Baseline data were not different when NICUs using aminoglycosides (n = 9965 infants) were compared to NICUs using other antibiotics (n = 1948 infants). Rates of surgical PDA closure were 5.9% for NICUs using aminoglycosides; 6.2% for units using gentamicin; and 5.0% for NICUs using tobramycin compared to 4.1% in NICUs using other antibiotics (P < .001, P < .001 and P = .140, respectively, Fisher's exact test). Indomethacin and ibuprofen use was more common in NICUs using aminoglycosides (41% vs 33%, P < .001, Fisher's exact test). Gentamicin trough levels were higher in NICUs with surgical closure rates above the mean (median 2.0 µg/mL, inter-quartile range 0.8-4.0 µg/mL vs 1.2 µg/mL, IQR 0.8-1.7, P < .001, Mann-Whitney U test). CONCLUSION First-line antibiotic treatment of preterm infants with aminoglycosides was associated with higher rates of surgical PDA closure.

Abstract
Background Data on the effectiveness of oral ibuprofen treatment for patent ductus arteriosus are limited, and the factors affecting its effectiveness remain unclear. Objective The aim was to identify the potential factors affecting the clinical effectiveness of oral ibuprofen in preterm infants. Setting Neonatal intensive care unit in a prefecture-level maternal and child healthcare hospital in China. Method Over a 5-years period, the medical records of 327 preterm infants with patent ductus arteriosus who were admitted to the neonatal intensive care unit of our hospital to receive a single course of oral ibuprofen were retrospectively reviewed. Main outcome measures The prevalence of risk factors affecting the effectiveness of oral ibuprofen. Results In total, 201 (61.47%) preterm infants were considered to have undergone "effective therapy" and classified accordingly, whereas 11 (3.36%) showed certain adverse events. Factors affecting therapeutic effectiveness were postnatal age at the initiation of treatment and Day 1/Day 0 ratio of urine output/fluid intake during the treatment course, with odds ratios of 0.892 (95% CI: 0.835-0.953; P = 0.001) and 0.473 (95% CI 0.265-0.845; P = 0.011), respectively. Conclusion A single course of oral ibuprofen for patent ductus arteriosus closure among preterm infants is effective and safe. Preterm infants with postnatal age of ≤ 9 days at the initiation of treatment and Day 1/Day 0 ratio of ≤ 0.708 of the urine output/fluid intake during the treatment course can be considered predictors of effectiveness of patent ductus arteriosus.

Abstract
The objective of this study was to assess the predictive value of a lung ultrasound (LUS) score in the development of moderate-severe bronchopulmonary dysplasia (sBPD). This was a prospective observational diagnostic accuracy study in a third-level neonatal intensive care unit. Preterm infants with a gestational age below 32 weeks were included. A LUS score (range 0-24 points) was calculated by assessing aeration semiquantitatively (0-3 points) in eight lung zones on the 7th day of life (DOL) and repeated on the 28th DOL. ROC curves and logistic regression were used for analysis. Forty-two preterm infants were included. The LUS on the 7th DOL had an area under the receiver operating characteristic curve (AUROC) of 0.94 (95% CI: 0.87-1) for the prediction of sBPD (optimal cutoff of ≥8 points: sensitivity 93%, specificity 91%). The LUS score was independently associated with sBPD [OR 2.1 (95% CI: 1.1-3.9), p = 0.022, for each additional point in the score]. Conclusions: Lung aeration as assessed by LUS on the 7th DOL may predict the development of sBPD.

Abstract
Bronchopulmonary dysplasia (BPD) is the most common chronic morbidity in preterm infants. In the absence of effective interventions, BPD is currently a major therapeutic challenge. Several risk factors are known for this multifactorial disease that results in disrupted lung development. Inflammation plays an important role and leads to persistent airway and pulmonary vascular disease. Since corticosteroids are potent anti-inflammatory agents, postnatal corticosteroids have been used widely for BPD prevention and treatment. However, the clinical responses vary to a great degree across individuals, and steroid-related complications remain major concerns. Emerging studies on the molecular mechanism of lung alveolarization during inflammatory stress will elucidate the complicated pathway and help discover novel therapeutic targets. Moreover, with the advances in metabolomics, there are new opportunities to identify biomarkers for early diagnosis and prognosis prediction of BPD. Pharmacometabolomics is another novel field aiming to identify the metabolomic changes before and after a specific drug treatment. Through this "metabolic signature," a more precise treatment may be developed, thereby avoiding unnecessary drug exposure in non-responders. In the future, more clinical, genetic, and translational studies would be required to improve the classification of BPD phenotypes and achieve individualized care to enhance the respiratory outcomes in preterm infants.

Abstract
OBJECTIVE Iatrogenic injury is a common cause of subglottic stenosis (SGS). We investigated the role of pre-injury dexamethasone as a preventive treatment for iatrogenic subglottic stenosis. METHODS 16 New Zealand White rabbits were used in an IACUC approved study. Subjects were divided into two groups: intramuscular dexamethasone (DEX) at a dose of 2 mg/kg 15 minutes prior to an endoscopic injury to create SGS, and the same injury creation with a preoperative intramuscular saline (SAL) injection. Three independent, blinded raters evaluated endoscopic images to obtain cross sectional area (CSA) airway measurements. Rabbit airways were measured just prior to injury and at one week post-injury. All subjects were provided as-needed postoperative steroids and buprenorphine for symptoms of respiratory distress. Data analysis was performed using Student t-test. Intraclass correlation coefficients were used to assess inter-rater agreement. RESULTS All subjects survived to the one-week post-injury airway evaluation. There was no difference in airway size between groups prior to injury (P = .28). Subjects in the DEX group demonstrated an average stenosis of 20.3% (95% CI 10.2-30.5) at one week compared to 60.6% (95% CI 40.3-80.9) in the SAL group (P = .01). Subjects in the control group required significantly more doses of postoperative dexamethasone (P = .02). Inter-rater agreement for between raters was excellent (ICC = .88). CONCLUSION This is the first study to examine the role of pre-injury glucocorticoids in preventing iatrogenic subglottic stenosis. In our model, a single dose of intramuscular dexamethasone given prior to a subglottic injury resulted in a statistically significant reduction in airway stenosis. This research suggests that administering systemic dexamethasone should be considered prior to any procedure that may injure the subglottis, including traumatic intubation, to prevent iatrogenic subglottic stenosis.
