BACKGROUND: Lung ultrasound (LUS) is a bedside technique that can be used on diagnosis and follow-up of neonatal respiratory diseases. However, there are rare reports on the ultrasound features of bronchopulmonary dysplasia (BPD) which is one of the most common chronic lung diseases in preterm infants. OBJECTIVE: To describe the ultrasound features of different BPD levels, and to investigate the value of ultrasound in evaluating moderate-to-severe BPD. METHODS: In this prospective cohort study, newborns of less than 37 weeks’ gestational age in neonatal intensive care unit (NICU) were included. The LUS characteristics including pleural line, alveolar-interstitial syndrome (AIS), retrodiaphragmatic hyperechogenicity and diaphragmatic morphology were observed and recorded. The reliability of LUS in evaluating moderate and severe BPD were compared and calculated. RESULTS: A total of 108 infants were enrolled in our study: 39, 24, 29, 16 infants had non, mild, moderate and severe BPD. The median(IQR) pleura thickness in the moderate-to-severe BPD group was 1.7(1.6–1.85) mm, which was thicker than that in the none-to-mild BPD infants (P <  0.001), meanwhile the proportions of rough pleural lines, diffuse AIS, retrodiaphragmatic hyperechogenicity, small cysts above the diaphragm and rough diaphragm in the moderate-to-severe BPD group were also higher than those in none-to-mild BPD group (86.7% vs 36.5, 57.8% vs 7.9%, 37.8% vs 0, 33.3% vs 0, P <  0.001). In evaluating moderate-to-severe BPD, rough pleura had 91.1% (95% confidence interval [CI]: 0.793–0.965) in sensitivity, 91.3% (95% CI: 0.797–0.966) in negative predictive value (NPV), and 66.7% (95% CI: 0.544–0.771) in specificity. Small cysts had 100% (95% CI: 0.941-1) in specificity, 100% (95% CI: 0.816-1) in PPV, and 37.8% in sensitivity (95% CI: 0.251–0.524). Rough diaphragm had 100% (95% CI: 0.943-1) in sensitivity, 100% (95% CI: 0.796-1) in PPV and 33.3% (95% CI: 0.211–0.478) in specificity. CONCLUSIONS: Depending on its unique advantages such as convenient, no radiation and repeatable, LUS is a valuable imaging method in assessing the severity of BPD, especially in moderate and severe BPD.

<b><i>Introduction:</i></b> Lung ultrasound (LUS) is useful for respiratory management in very preterm infants (VPI), but little is known about the echographic patterns in bronchopulmonary dysplasia (BPD), the relation between the image findings, and the severity of the disease and its long-term outcomes. We aimed to describe LUS patterns in BPD and analyze the accuracy of LUS to predict the need for respiratory support at 36 weeks postmenstrual age (PMA) in VPI. <b><i>Methods:</i></b> Preterm infants ≤30.6 weeks of gestational age were recruited. LUS was performed at admission, at 7th, and 28th day of life (DOL) with a standardized protocol (6 zones: anterior, lateral, and posterior fields). Clinical data, respiratory outcomes, and image findings were recorded. <b><i>Results:</i></b> Eighty-nine patients were studied. Infants with BPD had significantly higher LUS score at admission, at 7th, and 28th DOL. Patients with BPD exhibited more consolidations and pleural line abnormalities at 7th and 28th DOL than those without BPD (<i>p</i> &#x3c; 0.001), regardless of the definition used for BPD. LUS at 7th DOL predicted <i>NICHD 2001-BPD</i> with <i>R</i><sup>2</sup> = 0.522; AUC = 0.87 (0.79–0.94), <i>p</i> &#x3c; 0.001, and <i>Jensen 2019-BPD</i> with <i>R</i><sup>2</sup> = 0.315 (AUC = 0.80 [0.70–0.90], <i>p</i> &#x3c; 0.001). A model including mechanical ventilation &#x3e;5 days, oxygen therapy for 7 days and LUS score at 7th DOL accurately predicted the need for respiratory support at 36 weeks PMA (<i>R</i><sup>2</sup> = 0.655, <i>p</i> &#x3c; 0.001) with an AUC = 0.90 (0.84–0.97), <i>p</i> &#x3c; 0.001. <b><i>Conclusion:</i></b> LUS score, pleural line abnormalities, and consolidations can be useful to diagnose BPD in VPI and to predict its severity after the first week of life.

Objective This study aimed to determine the predictive abilities of the National Institute of Child Health and Human Development (NICHD) 2018 definition of bronchopulmonary dysplasia (BPD) on mortality and pulmonary outcomes of preterm infants at 20 to 24 months' corrected age and compare them with the National Institutes of Health (NIH) 2001 definition. Study Design A retrospective cohort study was conducted in a level III neonatal intensive care unit (NICU) in Bangkok, Thailand. Data from 502 infants less than 32 weeks of gestation born between 2011 and 2017 were reviewed. Follow-up data were available in 460 infants (91.6%). BPD severity was graded according to the NICHD 2018 and the NIH 2001 definitions. Infants' mortality and pulmonary outcomes were compared between these two definitions. Results The prevalence of BPD by the NIH 2001 and NICHD 2018 definition were 52.4 and 23.9%, respectively. Using the NIH 2001 definition, the severity of BPD could not be classified in 4.2% of the infants. Progressive severity of BPD by the NICHD 2018 definition was associated with higher incidence of pulmonary morbidities. By using area under the curve (AUC), the accuracy of NICHD 2018 definition in predicting death due to respiratory diseases and home oxygen therapy were significantly higher than those using NIH 2001 definition (0.884 vs. 0.740 [p <0.001] and 0.893 vs. 0.746 [p <0.001], respectively). Conclusion The NICHD 2018 definition of BPD categorized fewer preterm infants with BPD in our cohort of preterm infants. This current definition has better predictive ability on mortality and pulmonary morbidities than the NIH 2001 definition. Key Points

Abstract Background Patent ductus arteriosus poses diagnostic and therapeutic dilemma for clinicians, diagnosis of persistent PDA, and determination of its clinical and hemodynamic significance are challenging. The aim of this study is to determine the prevalence of PDA in preterm infants admitted to our NICU, to report cardiac and respiratory complications of PDA, and to study the management strategies and their subsequent outcomes. Result Echocardiography was done for 152 preterm babies admitted to neonatal intensive care unit (NICU) on day 3 of life. Eighty-seven (57.2%) preterms had PDA; 54 (62.1%) non-hemodynamically significant PDA (non-hsPDA), and 33 (37.9%) hemodynamically significant PDA. Hemodynamically significant PDA received medical treatment (paracetamol 15 mg/kg/6 h IV for 3 days). Follow-up echocadiography was done on day 7 of life. Four babies died before echo was done on day 7. Twenty babies (68.9%) achieved closure after 1st paracetamol course. Nine babies received 2nd course paracetamol. Follow-up echo done on day 11 of life showed 4 (13.7%) babies achieved successful medical closure after 2nd paracetamol course; 5 babies failed closure and were assigned for surgical ligation. The group of non-hsPDA showed spontaneous closure after conservative treatment. Pulmonary hemorrhage was significantly higher in hsPDA group. Mortality was higher in hsPDA group than non-hsPDA group. Conclusion Echocardiographic evaluation should be done for all preterms suspected clinically of having PDA. We should not expose vulnerable population of preterm infants to medication with known side effects unnecessarily; we should limit medical closure of PDA to hsPDA. Paracetamol offers several important therapeutic advantages options being well tolerated and having more favorable side effects profile.

SUMMARYThe aim of this study was to describe the incidence and risk factors for respiratory morbidity during the 12-month period following the first respiratory syncytial virus (RSV) season in 242 preterm infants [<33 weeks gestational age (GA)] without bronchopulmonary dysplasia and 201 full-term infants (39–41 weeks GA) from the French CASTOR study cohort. Preterm infants had increased respiratory morbidity during the follow-up period compared to full-terms; they were more likely to have wheezing (21% vs. 11%, P = 0·007) and recurrent wheezing episodes (4% vs. 1%, P = 0·049). The 17 infants (14 preterms, three full-terms) who had been hospitalized for RSV-confirmed bronchiolitis during their first RSV season had significantly more wheezing episodes during the follow-up period than subjects who had not been hospitalized for RSV-confirmed bronchiolitis (odds ratio 4·72, 95% confidence interval 1·71–13·08, P = 0·003). Male gender, birth weight <3330 g and hospitalization for RSV bronchiolitis during the infant's first RSV season were independent risk factors for the development of wheezing episodes during the subsequent 12-month follow-up period.

A qualitative study which has Symbolic Interactionism as theoretical framework and Interpretative Interactionism as its methodological one, aiming to unveil motherly experiences against prematurity peculiarities that hinder breastfeeding during infant's hospitalization at the Neonatal Intensive Care Unit. Were interviewed 13 mothers of preterm infants assisted at an Outpatient Follow-up Clinic of Montes Claros MG, Brazil. Results show that as trying to breastfeed a premature infant, the mother interacts with situations signified by her as obstacles to breastfeeding: the "torment" of their child's hospitalization and clinical instability, the fear of baby's death, its difficulty to suck, the late start of breastfeeding interpreted a something difficult, as a risk to weight. We consider that although breastfeeding a preterm infant is a challenge, appropriate professional conducts and hospital procedures might facilitate it and therefore should be implemented, aiming at promoting, protecting and supporting breastfeeding.

Introduction: Up to 29% of late preterm babies suffer from respiratory distress due to which they need to be admitted to neonatal intensive care unit (NICU). Point-of-care ultrasound is a useful tool in critical neonate care, providing valuable information without any risk of ionizing radiation to the newborn. Materials and Method: This mono-centric, descriptive, and prospective study was conducted in NICU. Preterm newborns of less than 36 weeks with respiratory distress at birth on non-invasive ventilation were recruited. A lung ultrasound was performed at first 12 h of life and followed till their discharge. Main outcomes need for surfactant treatment. Results: Sixty preterm infants (median gestational age: 29 weeks) were recruited. Newborn in the surfactant group requiring ultrasound and intervention was significantly higher than in no surfactant group (p<0.0001). In 15 newborns who received surfactant, the first dose was administered at a median age of 4.5 h. In 13 of these 15 newborns, the lung ultrasound scan was subsequently repeated an average of 2 h (Standard deviation or SD: 2) On average, the second dose of surfactant was administered at 24 h of life (SD: 9). Conclusion: Early lung ultrasound in preterm infants with respiratory distress appears to be a useful tool with no adverse effects for the patient. It allows a better assessment of respiratory distress by detecting patients with a greater risk of requiring surfactant or mechanical ventilation, even before oxygenation criteria.
