Abstract
Respiratory disease is one of the most common complications of preterm birth. Survivors of prematurity have increased risks of morbidities and mortalities independent of prematurity, and frequently require multiple medications, home respiratory support, and subspecialty care to maintain health. Although advances in neonatal and pulmonary care have improved overall survival, earlier gestational age, lower birth weight, chorioamnionitis and late onset sepsis continue to be major factors in the development of bronchopulmonary dysplasia. These early life events associated with prematurity can have respiratory consequences that persist into adulthood. Furthermore, after initial hospital discharge, air pollution, respiratory tract infections and socioeconomic status may modify lung growth trajectories and influence respiratory outcomes in later life. Given that the incidence of respiratory disease associated with prematurity remains stable or increased, there is a need for pediatric and adult providers to be familiar with the natural history, manifestations, and common complications of disease.

Abstract
BACKGROUND Infants born extremely premature (EP) (<28 weeks gestational age) are at high risk of complications, particularly bronchopulmonary dysplasia (BPD), which can develop into chronic lung disease (CLD). METHODS The burden of respiratory complications in EP infants up to 2 years corrected age (CA) was evaluated using real-world data from the US Medicaid program. Data recorded between 1997 and 2018 on EP infants without major congenital malformations were collected from Medicaid records of six states. EP infants were divided into three cohorts: BPD, CLD, and without BPD or CLD. The incidence of respiratory conditions, respiratory medication use, and healthcare resource utilization were compared between the BPD cohort and CLD cohort versus the cohort without BPD or CLD, using unadjusted and adjusted generalized linear models. RESULTS A total of 4462 EP infants were identified (17.4% of all premature infants in the database). Of these, BPD and CLD were diagnosed in 61.9% and 72.1%, respectively, and 14.5% were diagnosed with neither BPD nor CLD. Compared with infants without BPD or CLD, infants with BPD or CLD had more complications and a longer length of birth hospitalization stay. Respiratory distress syndrome was the most frequently reported complication (94.6%, 92.5%, and 82.3% of EP infants in the BPD, CLD, and without BPD or CLD cohorts, respectively). After the birth hospitalization, respiratory conditions, respiratory medication use, and incidence rates of rehospitalizations, emergency room visits, and outpatient visits were higher for infants with BPD or CLD. Rehospitalization occurred in 50.5%, 51.6%, and 27.3% of EP infants with BPD, CLD, or without BPD or CLD, respectively; most hospitalizations occurred for respiratory-related reasons. CONCLUSION In this analysis of a large population of EP infants up to 2 years CA, respiratory conditions were prevalent after the birth hospitalization and were associated with high rates of medication and healthcare resource utilization.

Abstract
For the newborns needing respiratory support at 36 weeks postmenstrual age, regardless of the type of ventilation used, it is critical to take into account the mechanics properties of both airways and lungs affected by severe bronchopulmonary dysplasia (sBPD). Ventilator strategies, settings, and weaning must change dramatically after sBPD is established, but to date there is almost no high-quality evidence base supporting a specific approach to guide the optimal ventilator management and weaning in patients with sBPD. Weaning from invasive mechanical ventilation, management of the immediately postextubation period, and weaning from noninvasive ventilation in patients with sBPD are the topics covered in this chapter.

Abstract
For infants with the most severe forms of chronic lung disease, regardless of etiology, chronic mechanical ventilation can provide stability, reduce acute respiratory events, and alleviate increased work of breathing. This approach prioritizes the baby's growth and development during early life. Once breathing comfortably, these infants can tolerate developmental therapies with the goal of achieving the best neurocognitive outcomes possible.

Abstract
Although survival has improved dramatically for extremely preterm infants, those with the most severe forms of bronchopulmonary dysplasia (BPD) fail to improve in the neonatal period and go on to develop chronic respiratory failure. When careful weaning of respiratory support is not tolerated, the difficult decision of whether or not to pursue chronic ventilation via tracheostomy must be made. This requires shared decision-making with an interdisciplinary medical team and the child's family. Although they suffer from increased morbidity and mortality, the majority of these children will survive to tolerate ventilator liberation and tracheostomy decannulation. Care coordination for the technology-dependent preterm infant is complex, but there is a growing consensus that chronic ventilation can best support neurodevelopmental progress and improve long-term outcomes.

Abstract
OBJECTIVE To determine the trends in tracheostomy placement and resource use in preterm infants less than or equal to 30 weeks gestational age (GA) with bronchopulmonary dysplasia (BPD) in the United States from 2008 to 2017. STUDY DESIGN This was a retrospective, serial cross-sectional study using data from the NIS. Inclusion criteria were: GA less than or equal to 30 weeks, hospitalization at less than or equal to 28 days of age, assignment of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD9-CM) or ICD10-CM codes for BPD and tracheostomy. Trends in tracheostomy and resource utilization were assessed using Jonckheere-Terpstra test. p-value < .05 was considered significant. RESULTS Overall, 987 out of 68,953 (1.4%) hospitalizations with BPD had tracheostomy. Characteristics of the study population: 60.8% were male, 68.4% less than or equal to 26 weeks GA, 43.8% White, 60.5% with Medicaid or self-pay, 65.2% in the Midwest and South census regions of the United States, and 45.7% had gastrostomy tube placement. Tracheostomy placement (expressed as per 100,000 live births) decreased from 2.7 in 2008 to 1.9 in 2011. Thereafter, it increased from 1.9 in 2011 to 3.5 in 2017 (p < .001). GA less than or equal to 24 weeks was significantly associated with increased odds of tracheostomy placement. Median length of stay increased significantly from 170 to 231 days while median inflation adjusted hospital cost increased significantly from $323,091 in 2008-2009 to $687,141 between 2008-2009 and 2016-2017. CONCLUSION Although tracheostomy placement among preterm hospitalizations with BPD was rare, the frequency of its placement and its associated resource utilization significantly increased during the study period. Future studies should probe the reasons and factors behind these trends.

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
OBJECTIVES To study a case series of preterm and extremely preterm infants, comparing their decannulation and survival rates after tracheostomy. METHODS We performed a single-institution longitudinal study of preterm infants with a tracheostomy. Infants were categorized as premature (born > 28 weeks and < 37 weeks) and extremely premature (born ≤ 28 weeks). Decannulation and survival rates were determined using the Kaplan-Meier method. Neurocognitive quality of life (QOL) was reported as normal, mild/moderately, and severely impaired. Statistical significance was set at P < .05. RESULTS This study included 240 patients. Of those, 111 were premature and 129 were extremely preterm. The median age (interquartile range) at tracheostomy was 4.8 months (0.4). Premature infants were more likely than extremely preterm to have airway obstruction (54% vs. 32%, P < .001); whereas extremely preterm infants were more likely to have bronchopulmonary dysplasia (68% vs. 15%, P < .001) and to be ventilation-dependent (68% vs. 54%, P < .001). The 5-year decannulation rate for premature infants was 46% and for extremely preterm was 64%. The 5-year survival rate post-tracheostomy for preterm was 79% and for extremely preterm was 73%. The log-rank test of equality showed that decannulation and survival were similar (P > .05) for both groups, even after controlling for potentially confounding factors like race, age, gender, birth weight, and age at tracheostomy. For neurocognitive QOL, 47% of patients survived with severely impaired QOL after tracheostomy. Preterm had 56% with severely impaired QOL and extremely preterm had 40% with severely impaired QOL (P = .03). CONCLUSION This study demonstrated that the time to decannulation and the likelihood of survival did not vary among premature and extremely premature infants even when controlling for other confounding variables.

Abstract
Ongoing advancements in neonatal care since the late 1980s have led to increased numbers of premature infants surviving well beyond the neonatal period. As a result of increased survival, many individuals born preterm manifest chronic respiratory symptoms throughout infancy, childhood, and adult life. The archetypical respiratory disease of prematurity, bronchopulmonary dysplasia, is the second most common chronic pediatric respiratory disease after asthma. However, there are several commonly held misconceptions. These misconceptions include that bronchopulmonary dysplasia is rare, that bronchopulmonary dysplasia resolves within the first few years of life, and that bronchopulmonary dysplasia does not impact respiratory health in adult life. This focused review describes a spectrum of respiratory conditions that individuals born prematurely may experience throughout their lifespan. Specifically, this review provides quantitative estimates of the number of individuals with alveolar, airway, and vascular phenotypes associated with bronchopulmonary dysplasia, as well as non-bronchopulmonary dysplasia respiratory phenotypes such as airway malacia, obstructive sleep apnea, and control of breathing issues. Furthermore, this review illustrates what is known about the potential for progression and/or lack of resolution of these respiratory phenotypes in childhood and adult life. Recognizing the spectrum of respiratory phenotypes associated with individuals born preterm and providing comprehensive and personalized care to these individuals may help to modulate adverse respiratory outcomes in later life.

Abstract
PURPOSE OF REVIEW Modern medical advances have resulted in an increased survival after extremely preterm birth. However, some infants will develop severe bronchopulmonary dysplasia (BPD) and fail to wean from invasive or noninvasive positive pressure support. It remains unclear which infants will benefit from tracheostomy placement for chronic ventilation. Once the decision to pursue chronic ventilation has been made, questions remain with respect to the timing of tracheotomy surgery, optimal strategies for mechanical ventilation, and multidisciplinary care in both the inpatient and outpatient settings. The appropriate time for weaning mechanical ventilation and tracheostomy decannulation has similarly not been determined. RECENT FINDINGS Although there remains a paucity of randomized controlled trials involving infants with severe BPD, a growing body of evidence suggests that chronic ventilation via tracheostomy is beneficial to support the growth and development of severely affected preterm children. However, delivering such care is not without risk. Chronic ventilation via tracheostomy requires complex care coordination and significant resource utilization. SUMMARY When chronic respiratory insufficiency limits a preterm infant's ability to grow and develop, chronic invasive ventilation may facilitate neurodevelopmental progress and may lead to an improved long-term outcome.
