Exploring the Association of Male Sex With Adverse Outcomes in Severe Bronchopulmonary Dysplasia: A Retrospective, Multicenter Cohort Study. Chest 2024; 165:610-620. [PMID: 37879559 DOI: 10.1016/j.chest.2023.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 09/12/2023] [Accepted: 10/05/2023] [Indexed: 10/27/2023] Open
Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) is a significant contributor to morbidity and death in infants who are born premature. Male sex is an independent risk factor for the development of BPD. However, whether male sex is associated with adverse outcomes that occur after formal diagnosis of severe BPD prior to hospital discharge remains unclear. RESEARCH QUESTION Is male sex associated with a higher risk of adverse outcomes in infants with established severe BPD? STUDY DESIGN AND METHODS A retrospective, multicenter cohort study of infants enrolled in the BPD Collaborative Registry from January 1, 2015, to June 29, 2022, was performed. Demographics, clinical characteristics, and outcomes were stratified by sex (ie, male vs female). Regression modeling was used to estimate the association of sex with the primary composite outcome of death or tracheostomy at hospital discharge. RESULTS We identified 1,156 infants with severe BPD, defined at 36 weeks postmenstrual age by the National Institutes of Health 2001 consensus definition. The cohort was predominantly male (59% male infants, 41% female infants). However, rates of mechanical ventilation at 36 weeks postmenstrual age (ie, type 2 severe BPD) did not differ by sex. Overall mortality rates within the cohort were low (male infants, 5.3%; female infants, 3.6%). The OR of death or tracheostomy for male-to-female infants was 1.0 (95% CI, 0.7-1.5). INTERPRETATION Our results lead us to speculate that, although sex is an important variable that contributes to the development and pathogenesis of severe BPD, it does not appear to be associated with adverse outcomes in this cohort of infants with established disease. The surprising results raise important questions surrounding the temporal role of biological sex in the development of severe BPD and its progression during the neonatal ICU stay. As we explore the phenotypes and endotypes of BPD, it is imperative to consider how sex modulates the disease from birth through hospital discharge.

Pediatr Pulmonol 2024. [PMID: 38165155 DOI: 10.1002/ppul.26837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 11/17/2023] [Accepted: 12/14/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Premature infants surviving beyond a postmenstrual age (PMA) of 36 weeks with severe or grade 3 bronchopulmonary dysplasia (sBPD) have significant predischarge mortality. The in-hospital mortality for BPD supported by invasive mechanical ventilation beyond 36 weeks PMA is not well described. The role of lung transplantation in treating severe BPD is uncertain. We studied our experience over 20 years to better define the predischarge mortality of infants with progressive grade 3 BPD and whether lung transplant is a feasible intervention. METHODS Data were obtained from a retrospective review of medical records from Children's Minnesota over a 20-year period (1997-2016). Inclusion criteria included prematurity <32 weeks PMA, BPD, tracheostomy for chronic respiratory failure, and survival beyond 36 weeks PMA. Collected data included perinatal demographics, in-hospital medications and interventions, level of respiratory support, and outcomes. RESULTS In all, 2374 infants were identified who survived beyond 36 weeks PMA with a diagnosis of <32 weeks gestation prematurity and BPD. Of these, 143/2374 (6.0%) survived beyond 36 weeks PMA and required invasive mechanical ventilation with subsequent tracheostomy for management. Among these patients, discharge to home with tracheostomy occurred in 127/143 (88.8%), and predischarge death or lung transplantation occurred in 16/143 (11.2%). Deteriorating cardiopulmonary status was associated with pulmonary hypertension, prolonged hypoxemic episodes and the need for deep sedation or neuromuscular relaxation. Three of four patients referred for lung transplantation had >5-year survival, chronic allograft rejection, and mild to moderate developmental delays. CONCLUSIONS Chronic respiratory failure requiring invasive mechanical ventilation for grade 3 BPD is associated with significant morbidity and mortality. For selected patients and their families, timely referral for lung transplantation is a viable option for end-stage grade 3 BPD. As in other infants receiving solid organ transplants, long-term issues with co-morbidities and special needs persist into childhood.

Abstract
OBJECTIVE We evaluated what placental pathologies were associated with adverse preterm births. MATERIALS AND METHODS Placental findings, classified according to the Amsterdam criteria, were correlated with infant outcomes. The fetal vascular lesions, inflammatory responses other than histological chorioamnionitis (HCA), and placentas with combined maternal vascular malperfusion (MVM) and HCA were excluded. RESULTS A total of 772 placentas were evaluated. MVM was present in 394 placentas, HCA in 378. Early neonatal sepsis, retinopathy of prematurity, necrotizing enterocolitis, and neonatal death occurred more often in the MVM-only group than HCA-only group. The frequency of bronchopulmonary dysplasia (BPD) was 38.6% in the HCA-only group, and it was 20.3% in the MVM-only group (p < 0.001). HCA was the most important independent risk factor for BPD (OR 3.877, 95% CI 2.831-5.312). CONCLUSION Inflammation in the placenta influences fetal and neonatal outcomes. HCA is an independent risk factor for BPD.

Risk factors that affect the degree of bronchopulmonary dysplasia in very preterm infants: a 5-year retrospective study. BMC Pediatr 2022; 22:200. [PMID: 35413820 PMCID: PMC9004103 DOI: 10.1186/s12887-022-03273-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Accepted: 04/04/2022] [Indexed: 11/10/2022] Open
Abstract
Background Bronchopulmonary dysplasia (BPD) is one of the most common adverse consequence of premature delivery and the most common chronic lung disease in infants. BPD is associated with long-term lung diseases and neurodevelopmental disorders that can persist into the adulthood. The adverse consequences caused by severe BPD are more serious. However, there were few studies on the risk factors for severe BPD. Methods This is a retrospective study of preterm infants born less than 32-week gestational age (GA) and diagnosed with BPD. Results A total of 250 preterm infants with a diagnosis of BPD and GA < 32 weeks were included (137 boys [54.8%] and 113 girls [45.2%]). The birth weight ranged from 700 g to 2010 g and the mean birth weight was 1318.52 g (255.45 g). The GA ranged from 25 weeks to 31 weeks and 6 days (mean, 30 weeks). The number of cases of mild, moderate and severe BPD were 39 (15.6%), 185 (74.0%) and 26 (10.4%), respectively. There were significant differences in the rate of small for gestational age (SGA), intrauterine asphyxia, pulmonary hemorrhage, neonatal respiratory distress syndrome (NRDS), circulatory failure, pulmonary hypertension, patent ductus arteriosus (PDA), pulmonary surfactant (PS), aminophylline, caffeine, glucocorticoids, tracheal intubation, diuretics, and parenteral nutrition length among the three groups (P < 0.05). The time of parenteral nutrition (aOR = 3.343, 95%CI: 2.198 ~ 5.085) and PDA (aOR =9.441, 95%CI: 1.186 ~ 75.128) were independent risk factors for severe BPD compared with mild BPD. PDA (aOR = 5.202, 95%CI: 1.803 ~ 15.010) and aminophylline (aOR = 6.179, 95%CI: 2.200 ~ 17.353) were independent risk factors for severe BPD, while caffeine (aOR = 0.260, 95%CI: 0.092 ~ 0.736) was the protective factor for severe BPD compared with moderate BPD. The time of parenteral nutrition (aOR = 2.972, 95%CI: 1.989 ~ 4.440) and caffeine (aOR = 4.525, 95%CI: 1.042 ~ 19.649) were independent risk factors for moderate BPD compared with mild BPD. Caffeine (aOR = 3.850, 95%CI: 1.358 ~ 10.916) was the independent risk factor for moderate BPD, while PDA (aOR = 0.192, 95%CI: 0.067 ~ 0.555) and aminophylline (aOR = 0.162, 95%CI: 0.058 ~ 0.455) were protective factors for moderate BPD compared with severe BPD. The time of parenteral nutrition (aOR = 0.337, 95%CI: 0.225 ~ 0.503) and caffeine (aOR = 0.221, 95%CI: 0.051 ~ 0.960) were protective factors for mild BPD compared with moderate BPD. The time of parenteral nutrition (aOR = 0.299, 95%CI: 0.197 ~ 0.455) and PDA (aOR = 0.106, 95%CI: 0.013 ~ 0.843) were protective factors for mild BPD compared with severe BPD. Conclusion The time of parenteral nutrition is the risk factor of moderate and severe BPD. PDA and aminophylline are risk factors for severe BPD. The role of caffeine in the severity of BPD is uncertain, and SGA is not related to the severity of BPD. Severe or moderate BPD can be avoided by shortening duration of parenteral nutrition, early treatment of PDA, reducing use of aminophylline and rational use of caffeine. Trial registration Retrospectively registered.

Abstract
OBJECTIVE To characterize the safety of sildenafil in premature infants. STUDY DESIGN A phase I, open-label trial of sildenafil in premature infants receiving sildenafil per usual clinical care (cohort 1) or receiving a single IV dose of sildenafil (cohort 2). Safety was evaluated based on adverse events (AEs), transaminase levels, and mean arterial pressure monitoring. RESULTS Twenty-four infants in cohort 1 (n = 25) received enteral sildenafil. In cohort 2, infants received a single IV sildenafil dose of 0.25 mg/kg (n = 7) or 0.125 mg/kg (n = 2). In cohort 2, there was one serious AE related to study drug involving hypotension associated with a faster infusion rate than specified by the protocol. There were no AEs related to elevated transaminases. CONCLUSION Sildenafil was well tolerated by the study population. Drug administration times and flush rates require careful attention to prevent infusion-related hypotension associated with faster infusions of IV sildenafil in premature infants.

Abstract
OBJECTIVE To compare three bronchopulmonary dysplasia (BPD) definitions against hospital outcomes in a referral-based population. STUDY DESIGN Data from the Children's Hospitals Neonatal Consortium were classified by 2018 NICHD, 2019 NRN, and Canadian Neonatal Network (CNN) BPD definitions. Multivariable models evaluated the associations between BPD severity and death, tracheostomy, or length of stay, relative to No BPD references. RESULTS Mortality was highest in 2019 NRN Grade 3 infants (aOR 225), followed by 2018 NICHD Grade 3 (aOR 145). Infants with lower BPD grades rarely died (<1%), but Grade 2 infants had aOR 7-21-fold higher for death and 23-56-fold higher for tracheostomy. CONCLUSIONS Definitions with 3 BPD grades had better discrimination and Grade 3 2019 NRN had the strongest association with outcomes. No/Grade 1 infants rarely had severe outcomes, but Grade 2 infants were at risk. These data may be useful for counseling families and determining therapies for infants with BPD.

Abstract
INTRODUCTION Moderate and severe bronchopulmonary dysplasia (BPD) is a common pulmonary complication in premature infants, which seriously affects their survival rate and quality of life. This study aimed to describe the mechanical ventilation characteristics and evaluate their prediction performance for the risk of moderate and severe BPD in infants with gestational age <30 weeks and birth weight <1,500 g on postnatal Day 14. METHODS In this retrospective cohort study, 412 infants with gestational age <30 weeks and birth weight <1,500 g were included in the analysis, including 104 infants with moderate and severe BPD and 308 infants without moderate and severe BPD (as controls). LASSO regression was used to optimize variable selection, and Logistic regression was applied to build a predictive model. Nomograms were developed visually using the selected variables. To validate the model, receiver operating characteristic (ROC) curve, calibration plot, and clinical impact curve were used. RESULTS From the original 28 variables studied, six predictors, namely birth weight, 5 min apgar score, neonatal respiratory distress syndrome (≥Class II), neonatal pneumonia, duration of invasive mechanical ventilation (IMV) and maximum of FiO2 (fraction of inspiration O2) were identified by LASSO regression analysis. The model constructed using these six predictors and a proven risk factor (gestational age) displayed good prediction performance for moderate and severe BPD, with an area under the ROC of 0.917 (sensitivity = 0.897, specificity = 0.797) in the training set and 0.931 (sensitivity = 0.885, specificity = 0.844) in the validation set, and was well calibrated (P Hosmer-Lemeshow test = 0.727 and 0.809 for the training and validation set, respectively). CONCLUSION The model included gestational age, birth weight, 5 min apgar score, neonatal respiratory distress syndrome (≥Class II), neonatal pneumonia, duration of IMV and maximum of FiO2 had good prediction performance for predicting moderate and severe BPD in infants with gestational age <30 weeks and birth weight <1,500 g on postnatal Day 14.

Abstract
OBJECTIVE The decision for tracheostomy for bronchopulmonary dysplasia (BPD) is highly variable and often dictated by local practice. We aimed to characterize morbidity, mortality, and respiratory outcomes in preterm infants undergoing tracheostomy for severe BPD. STUDY DESIGN We retrospectively reviewed a single-center 4-year cohort of all infants born <33 weeks gestational age (GA) that required tracheostomy due to severe BPD. Indications for tracheostomy apart from BPD were excluded. Demographic information, comorbidities, respiratory management, age at tracheostomy, post-discharge respiratory outcomes, and survival were examined up to at least 5 years of age. RESULTS At a mean corrected GA of 43.3 weeks, 49 preterm infants with severe BPD required tracheostomy. Forty-six infants (94%) had long-term follow-up. Compared to survivors, the 12 (26.1%) infants that died were significantly more likely to be small for gestational age (SGA) or require treatment for pulmonary hypertension. GA, birth weight, sex, antenatal corticosteroid exposure, need for patent ductus arteriosus ligation, and magnitude of respiratory support at tracheostomy placement were not associated with mortality. At the latest follow-up, 97% were liberated from mechanical ventilation and 79% decannulated. Morbidities of the upper airway were common, and 13/27 (47%) decannulated infants had required airway reconstruction. CONCLUSION Preterm infants undergoing tracheostomy experienced significant mortality, particularly those who were SGA or had pulmonary hypertension. However, by 5 years of age, most infants liberalized from mechanical ventilation and decannulated. Magnitude of respiratory support at time of tracheostomy was not associated with mortality and should not deter intervention. Nearly half of patients required airway reconstruction before decannulation.

Abstract
OBJECTIVE This study was designed to explore the efficacy of budesonide (BUD) in preventing and treating bronchopulmonary dysplasia (BPD) in premature infants and its effect on pulmonary function. METHODS A total of 94 premature infants with BPD who were born in our hospital were selected as the research subjects and divided into the control group (47 cases) for routine treatment and the research group (47 cases) for BUD therapy on the basis of routine treatment according to the random number table method. The incidence of BPD and the time of oxygen inhalation, ventilator ventilation, extubation and hospitalization were recorded in the two groups. In addition, arterial blood gas indexes (arterial oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2)), inflammatory response indicators (interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor (TNF-α)), pulmonary function indexes (the ratio of time taken to reach peak expiratory flow to total expiratory time (TPTEF/TE), the ratio of peak expiratory volume to total expiratory volume (VPEF/VE), tidal expiratory flow at 25%/50%/75% remaining tidal volume (TEF25, TEF50, TEF75), and the incidence of complications were observed and compared. RESULTS After treatment, SaO2 and PaO2 increased in both groups, and their values in the research group were higher than those in the control group; PaCO2 decreased in both groups, and the PaCO2 in the research group was lower than that in the control group (P<0.05). The post-treatment TNF-α, IL-6 and IL-8 levels decreased in both groups, and their levels in the research group were lower than those in the control group (all P<0.001). TPTEE/TE, VPEF/VE, TEF25, TEF50 and TEF75 increased in both groups after treatment, and their values in the research group were higher than those in the control group (all P<0.01). The research group required shorter oxygen inhalation time, ventilator ventilation time, time to extubation and hospitalization time than the control group (all P<0.001). The incidence of BPD and other complications in the research group were lower than that in the control group (8.51%, 6.38% vs. 23.40%, 21.28%; P=0.049, 0.036). CONCLUSION BUD is effective in the prevention and treatment of BPD in premature infants, which can effectively reduce the incidence of BPD and other complications, improve blood gas indexes, reduce inflammatory reactions and promotes good pulmonary function in children.

Abstract
BACKGROUND Some infants with severe bronchopulmonary dysplasia (sBPD) are referred to higher-level centers for multidisciplinary care, including the pediatric intensive care unit (PICU). However, information regarding these infants is limited in PICUs. METHODS We investigated the characteristics and outcomes of preterm infants with sBPD referred to the PICU of a tertiary hospital. This retrospective cohort study included 14 preterm infants with sBPD who were transferred to the PICU beyond 40 weeks' postmenstrual age (PMA) because of weaning failure, from January 1, 2014, to September 30, 2018. RESULTS The median age at referral was 47.1 weeks (range, 43.6-55.9 weeks), and the median length of stay in the previous neonatal intensive care unit was 154 days (range, 105.8-202.3 days) after birth. After referral the following major comorbidities were found in the patients: large airway malacia, n = 7 (50.0%); significant upper airway obstruction, n = 3 (21.4%); and pulmonary arterial hypertension, n = 8 patients (57.1%). Finally, eight patients (57.1%) were successfully extubated without tracheostomy. Final respiratory support of the patients was determined at a median PMA of 56 weeks (range, 48-63 weeks). Age at referral (P = 0.023) and large airway obstruction (P = 0.028) were significantly related to a decrease in successful extubation. CONCLUSION Based on a timely and individualized multidisciplinary approach, some of the prolonged ventilator-dependent infants, even those beyond term age, could be successfully extubated.

Abstract
Background Pulmonary hypertension is a deadly complication of bronchopulmonary dysplasia, the most common pulmonary morbidity of prematurity. Despite these catastrophic consequences, no evidence-based therapies are available for the prevention of pulmonary hypertension in this population. Sildenafil is a potent pulmonary vasodilator approved by the US Food and Drug Administration for the treatment of pulmonary hypertension in adults. Preclinical models suggest a beneficial effect of sildenafil on premature lungs through improved alveolarization and preserved vascular development. Sildenafil may therefore prevent the development of pulmonary hypertension associated with lung disease of prematurity by reducing pulmonary vascular remodeling and lowering pulmonary vascular resistance; however, clinical trial evidence is needed. The present study, supported by the National Institutes of Health’s National Heart Lung and Blood Institute, will generate safety, pharmacokinetics, and preliminary effectiveness data on sildenafil in a population of premature infants with severe bronchopulmonary dysplasia at risk for pulmonary hypertension. Methods We have designed a multicenter, randomized, placebo-controlled, sequential dose-escalating, double-masked, safety trial of sildenafil in premature infants with severe bronchopulmonary dysplasia. We will randomize 120 premature infants < 29 weeks gestational age with severe bronchopulmonary dysplasia at 32–40 weeks postmenstrual age in a dose-escalating approach 3:1 (sildenafil: placebo) sequentially into each of 3 cohorts at ~ 30 clinical sites. Participants will receive up to 34 days of study drug, followed by 28 days of safety monitoring. The primary outcome will be safety as determined by incidence of hypotension. Secondary outcomes will include pharmacokinetics and preliminary effectiveness of sildenafil based on presence or absence of pulmonary hypertension diagnosed by echocardiography at the end of treatment period. Discussion Sildenafil is a promising intervention to prevent the development of pulmonary hypertension in premature infants with bronchopulmonary dysplasia. Clinical trials of sildenafil specifically designed for premature infants are urgently needed. The current study will make substantial contributions to scientific knowledge of the safety of sildenafil in premature infants at risk for pulmonary hypertension. Results from the study will be used by investigators to inform the design of a pivotal efficacy trial. Trial registration ClinicalTrials.govNCT04447989. Registered 25 June 2020.

UNLABELLED : media-1vid110.1542/5849572914001PEDS-VA_2018-1951Video Abstract BACKGROUND: An increasing proportion of pediatric hospital days are attributed to technology-dependent children. The impact that a pediatric home care nursing (HCN) shortage has on increasing length of hospital stay and readmissions in this population is not well documented. METHODS We conducted a 12-month multisite prospective study of children with medical complexity discharging with home health. We studied the following 2 cohorts: new patients discharging for the first time to home nursing and existing patients discharging from the hospital to previously established home nursing. A modified delay tool was used to categorize causes, delayed discharge (DD) days, and unplanned 90-day readmissions. RESULTS DD occurred in 68.5% of 54 new patients and 9.2% of 131 existing patients. Lack of HCN was the most frequent cause of DD, increasing costs and directly accounting for an average length of stay increase of 53.9 days (range: 4-204) and 35.7 days (3-63) for new and existing patients, respectively. Of 1582 DDs, 1454 (91.9%) were directly attributed to lack of HCN availability. DD was associated with younger age and tracheostomy. Unplanned 90-day readmissions were due to medical setbacks (96.7% of cases) and occurred in 53.7% and 45.0% of new and existing patients, respectively. CONCLUSIONS DD and related costs are primarily associated with shortage of HCN and predominantly affect patients new to HCN. Medical setbacks are the most common causes of unplanned 90-day readmissions. Increasing the availability of home care nurses or postacute care facilities could reduce costly hospital length of stay.

Abstract
OBJECTIVE Longer initial hospitalizations for preterm infants with bronchopulmonary dysplasia (BPD) can delay family bonding and attainment of developmental milestones, increase the risk for hospital acquired complications, and increase healthcare costs. The goal of the study was to identify the characteristics associated with longer lengths of hospitalization in this high-risk population. STUDY DESIGN A retrospective analysis was performed on 660 children (born ≤32 weeks gestation) discharged from 13 Maryland NICUs recruited into an outpatient BPD registry. RESULT The mean age of discharge was 4.3 ± 2.9 months (median: 3.7 months). Subjects born with lower birthweights and covered by public insurance had longer lengths of hospitalization. Clinical characteristics at discharge associated with longer initial hospitalizations included gastrostomy tube, mechanical ventilation, tracheostomy, pulmonary hypertension, and supplemental oxygen. CONCLUSION Identifying the risk factors associated with longer lengths of stay could prompt the implementation of personalized in-hospital interventions to improve outcomes and minimize length of stay in infants with BPD.

Abstract
BACKGROUND Although highly beneficial, human milk feeding is challenging in preterm infants due to adverse NICU factors for the infant and mother. AIM To investigate the effects of an early intervention in promoting infant's human milk feeding and acquisition of full oral feeding. METHODS This study is part of a RCT. We included preterm infants born between 25+0 and 29+6 weeks of gestational age (GA) without severe morbidities, and their parents. Infants were randomized to either receive early intervention (EI) or standard care (SC). EI included PremieStart and parental training to promote infant massage and visual attention according to a detailed protocol. SC, in line with NICU protocols, included Kangaroo Mother Care. The time of acquisition of full oral feeding and human milk consumption at discharge were recorded. RESULTS Seventy preterm (EI n = 34, SC n = 36) infants were enrolled. Thirteen were excluded according to the protocol. Fifty-seven (EI n = 29, SC n = 28) infants were evaluated at discharge. The two groups were comparable for parent and infant characteristics. A significantly higher rate of infants fed with any human milk was observed in the EI group (75.9%) compared with the SC group (32.1%) (p = 0.001), and EI infants were four times more likely to be fed exclusively with human milk. Full oral feeding was achieved almost one week earlier in EI infants (mean postmenstrual age 36.8 ± 1.6 vs 37.9 ± 2.4 weeks in EI vs SC, p = 0.04). CONCLUSIONS Early interventions promoting mother self-efficacy and involvement in multisensory stimulation have beneficial effects on human milk feeding in preterm infants.
