RESUMEN
OBJECTIVE: To determine the association between indoor air pollution and respiratory morbidities in children with bronchopulmonary dysplasia (BPD) recruited from the multicenter BPD Collaborative. STUDY DESIGN: A cross-sectional study was performed among participants <3 years old in the BPD Collaborative Outpatient Registry. Indoor air pollution was defined as any reported exposure to tobacco or marijuana smoke, electronic cigarette emissions, gas stoves, and/or wood stoves. Clinical data included acute care use and chronic respiratory symptoms in the past 4 weeks. RESULTS: A total of 1011 participants born at a mean gestational age of 26.4 ± 2.2 weeks were included. Most (66.6%) had severe BPD. More than 40% of participants were exposed to ≥1 source of indoor air pollution. The odds of reporting an emergency department visit (OR, 1.7; 95% CI, 1.18-2.45), antibiotic use (OR, 1.9; 95% CI, 1.12-3.21), or a systemic steroid course (OR, 2.18; 95% CI, 1.24-3.84) were significantly higher in participants reporting exposure to secondhand smoke (SHS) compared with those without SHS exposure. Participants reporting exposure to air pollution (not including SHS) also had a significantly greater odds (OR, 1.48; 95% CI, 1.08-2.03) of antibiotic use as well. Indoor air pollution exposure (including SHS) was not associated with chronic respiratory symptoms or rescue medication use. CONCLUSIONS: Exposure to indoor air pollution, especially SHS, was associated with acute respiratory morbidities, including emergency department visits, antibiotics for respiratory illnesses, and systemic steroid use.
RESUMEN
von Willebrand factor (VWF) plays a key role in normal hemostasis, and deficiencies of VWF lead to clinically significant bleeding. We sought to identify novel modifiers of VWF levels in endothelial colony-forming cells (ECFCs) using single-cell RNA sequencing (scRNA-seq). ECFCs were isolated from patients with low VWF levels (plasma VWF antigen levels between 30 and 50 IU/dL) and from healthy controls. Human umbilical vein endothelial cells were used as an additional control cell line. Cells were characterized for their Weibel Palade body (WPB) content and VWF release. scRNA-seq of all cell lines was performed to evaluate for gene expression heterogeneity and for candidate modifiers of VWF regulation. Candidate modifiers identified by scRNA-seq were further characterized with small-interfering RNA (siRNA) experiments to evaluate for effects on VWF. We observed that ECFCs derived from patients with low VWF demonstrated alterations in baseline WPB metrics and exhibit impaired VWF release. scRNA-seq analyses of these endothelial cells revealed overall decreased VWF transcription, mosaicism of VWF expression, and genes that are differentially expressed in low VWF ECFCs and control endothelial cells (control ECs). An siRNA screen of potential VWF modifiers provided further evidence of regulatory candidates, and 1 such candidate, FLI1, alters the transcriptional activity of VWF. In conclusion, ECFCs from individuals with low VWF demonstrate alterations in their baseline VWF packaging and release compared with control ECs. scRNA-seq revealed alterations in VWF transcription, and siRNA screening identified multiple candidate regulators of VWF.

BACKGROUND: To characterize a cohort of ventilator-dependent infants and children with bronchopulmonary dysplasia-associated pulmonary hypertension (BPD-PH) and to describe their cardiorespiratory outcomes. METHODS: Subjects with BPD on chronic home ventilation were recruited from outpatient clinics. PH was defined by its presence on ≥1 cardiac catheterization or echocardiogram on or after 36 weeks post-menstrual age. Kaplan-Meier analysis was used to compare the timing of key events. RESULTS: Of the 154 subjects, 93 (60.4%) had PH and of those, 52 (55.9%) required PH-specific medications. The ages at tracheostomy, transition to home ventilator, and hospital discharge were older in those with PH. Most subjects were weaned off oxygen and liberated from the ventilator by 5 years of age, which did not occur later in subjects with PH. The mortality rate after initial discharge was 2.6%. CONCLUSIONS: The majority of infants with BPD-PH receiving chronic invasive ventilation at home survived after initial discharge. Subjects with BPD-PH improved over time as evidenced by weaning off oxygen and PH medications, ventilator liberation, and tracheostomy decannulation. While the presence of PH was not associated with later ventilator liberation or decannulation, the use of PH medications may be a marker of a more protracted disease trajectory. IMPACT STATEMENT: There is limited data on long-term outcomes of children with bronchopulmonary dysplasia (BPD) who receive chronic invasive ventilation at home, and no data on those with the comorbidity of pulmonary hypertension (PH). Almost all subjects with BPD-PH who were on chronic invasive ventilation at home survived after their initial hospital discharge. Subjects with BPD-PH improved over time as evidenced by weaning off oxygen, PH medications, liberation from the ventilator, and tracheostomy decannulation. The presence of PH did not result in later ventilator liberation or decannulation; however, the use of outpatient PH medications was associated with later ventilation liberation and decannulation.
RESUMEN
OBJECTIVES: To test the hypothesis that daycare attendance among children with bronchopulmonary dysplasia (BPD) is associated with increased chronic respiratory symptoms and/or greater health care use for respiratory illnesses during the first 3 years of life. STUDY DESIGN: Daycare attendance and clinical outcomes were obtained via standardized instruments for 341 subjects recruited from 9 BPD specialty clinics in the US. All subjects were former infants born preterm (<34 weeks) with BPD (71% severe) requiring outpatient follow-up between 0 and 3 years of age. Mixed logistic regression models were used to test for associations. RESULTS: Children with BPD attending daycare were more likely to have emergency department visits and systemic steroid usage. Children in daycare up to 3 years of age also were more likely to report trouble breathing, having activity limitations, and using rescue medications when compared with children not in daycare. More severe manifestations were found in children attending daycare between 6 and 12 months of chronological age. CONCLUSIONS: In this study, children born preterm with BPD who attend daycare were more likely to visit the emergency department, use systemic steroids, and have chronic respiratory symptoms compared with children not in daycare, indicating that daycare may be a potential modifiable risk factor to minimize respiratory morbidities in children with BPD during the preschool years.

Background: Premature birth affects millions of neonates each year, placing them at risk for respiratory disease due to prematurity. Bronchopulmonary dysplasia is the most common chronic lung disease of infancy, but recent data suggest that even premature infants who do not meet the strict definition of bronchopulmonary dysplasia can develop adverse pulmonary outcomes later in life. This post-prematurity respiratory disease (PPRD) manifests as chronic respiratory symptoms, including cough, recurrent wheezing, exercise limitation, and reduced pulmonary function. This document provides an evidence-based clinical practice guideline on the outpatient management of infants, children, and adolescents with PPRD. Methods: A multidisciplinary panel of experts posed questions regarding the outpatient management of PPRD. We conducted a systematic review of the relevant literature. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to rate the quality of evidence and the strength of the clinical recommendations. Results: The panel members considered the strength of each recommendation and evaluated the benefits and risks of applying the intervention. In formulating the recommendations, the panel considered patient and caregiver values, the cost of care, and feasibility. Recommendations were developed for or against three common medical therapies and four diagnostic evaluations in the context of the outpatient management of PPRD. Conclusions: The panel developed recommendations for the outpatient management of patients with PPRD on the basis of limited evidence and expert opinion. Important areas for future research were identified.

OBJECTIVE: Bronchopulmonary dysplasia (BPD) remains the most common late morbidity for extremely premature infants. Care of infants with BPD requires a longitudinal approach from the neonatal intensive care unit to ambulatory care though interdisciplinary programs. Current approaches for the development of optimal programs vary among centers. STUDY DESIGN: We conducted a survey of 18 academic centers that are members of the BPD Collaborative, a consortium of institutions with an established interdisciplinary BPD program. We aimed to characterize the approach, composition, and current practices of the interdisciplinary teams in inpatient and outpatient domains. RESULTS: Variations exist among centers, including composition of the interdisciplinary team, whether the team is the primary or consult service, timing of the first team assessment of the patient, frequency and nature of rounds during the hospitalization, and the timing of ambulatory visits postdischarge. CONCLUSION: Further studies to assess long-term outcomes are needed to optimize interdisciplinary care of infants with severe BPD. KEY POINTS: · Care of infants with BPD requires a longitudinal approach from the NICU to ambulatory care.. · Benefits of interdisciplinary care for children have been observed in other chronic conditions.. · Current approaches for the development of optimal interdisciplinary BPD programs vary among centers..
RESUMEN
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.

BACKGROUND: Preparing families of children requiring long-term mechanical ventilation (LTMV) to manage medical emergencies at home is challenging. Opportunities for family caregivers to rehearse crisis management in a controlled setting before discharge are limited. OBJECTIVE: We aimed to create a multimodal discharge preparedness curriculum, incorporating high-fidelity simulation training, to prepare family caregivers of children with complex medical conditions requiring long-term mechanical ventilation. We sought to determine which curricular elements were most helpful and whether this curriculum impacted the rate of readmissions within 7 days of hospital discharge. METHODS: The curriculum included instructional videos, printed handouts, cardiopulmonary resuscitation training, and two mandatory high fidelity simulation scenarios depicting tracheostomy- and ventilator-related emergencies. Teams of one to three family caregivers per patient managed each scenario. A video-based debriefing focused on identifying and closing performance gaps. Participants rated their perceptions regarding each curricular element and its relative impact on their preparedness for discharge. RESULTS: 87 family caregivers completed the curriculum. Simulation-enhanced curriculum was well-received by participants. Participants reported that post-simulation debriefing was the most beneficial component. We observed a trend toward reduced readmissions within 7 days of discharge since implementation of our revised curriculum. CONCLUSION: Simulation training can be incorporated into discharge training for families of children requiring LTMV. Rehearsal of emergency management in a simulated clinical setting increases caregiver confidence to assume care for their ventilator-dependent child.

BACKGROUND: In mediation analysis if unmeasured confounding is present, the estimates for the direct and mediated effects may be over or under estimated. Most methods for the sensitivity analysis of unmeasured confounding in mediation have focused on the mediator-outcome relationship. RESULTS: The Umediation R package enables the user to simulate unmeasured confounding of the exposure-mediator, exposure-outcome, and mediator-outcome relationships in order to see how the results of the mediation analysis would change in the presence of unmeasured confounding. We apply the Umediation package to the Genetic Epidemiology of Chronic Obstructive Pulmonary Disease (COPDGene) study to examine the role of unmeasured confounding due to population stratification on the effect of a single nucleotide polymorphism (SNP) in the CHRNA5/3/B4 locus on pulmonary function decline as mediated by cigarette smoking. CONCLUSIONS: Umediation is a flexible R package that examines the role of unmeasured confounding in mediation analysis allowing for normally distributed or Bernoulli distributed exposures, outcomes, mediators, measured confounders, and unmeasured confounders. Umediation also accommodates multiple measured confounders, multiple unmeasured confounders, and allows for a mediator-exposure interaction on the outcome. Umediation is available as an R package at https://github.com/SharonLutz/Umediation A tutorial on how to install and use the Umediation package is available in the Additional file 1.

BACKGROUND: Children with chronic invasive ventilator dependence living at home are a diverse group of children with special health care needs. Medical oversight, equipment management, and community resources vary widely. There are no clinical practice guidelines available to health care professionals for the safe hospital discharge and home management of these complex children. PURPOSE: To develop evidence-based clinical practice guidelines for the hospital discharge and home/community management of children requiring chronic invasive ventilation. METHODS: The Pediatric Assembly of the American Thoracic Society assembled an interdisciplinary workgroup with expertise in the care of children requiring chronic invasive ventilation. The experts developed four questions of clinical importance and used an evidence-based strategy to identify relevant medical evidence. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was used to formulate and grade recommendations. RESULTS: Clinical practice recommendations for the management of children with chronic ventilator dependence at home are provided, and the evidence supporting each recommendation is discussed. CONCLUSIONS: Collaborative generalist and subspecialist comanagement is the Medical Home model most likely to be successful for the care of children requiring chronic invasive ventilation. Standardized hospital discharge criteria are suggested. An awake, trained caregiver should be present at all times, and at least two family caregivers should be trained specifically for the child's care. Standardized equipment for monitoring, emergency preparedness, and airway clearance are outlined. The recommendations presented are based on the current evidence and expert opinion and will require an update as new evidence and/or technologies become available.

Background The clinical needs of infants with severe bronchopulmonary dysplasia (BPD) that remain ventilator-dependent are complex, and management strategies that optimize survival and long-term outcomes controversial. We hypothesized that an interdisciplinary ventilator care program (VCP), committed to the care of this population will improve survival through standardized approaches to cardiopulmonary care and related comorbidities, enhanced communication, and continuity of care. Methods Retrospective chart reviews were performed on patients at Children's Hospital Colorado's neonatal intensive care unit, who underwent tracheostomy placement between 2000 and 2013. Data were collected for two time periods: 2000 to 2005 and 2006 to 2013, before and after initiation of the VCP. Collected data on infants with ventilator-dependent BPD included: gestational age (GA), age at tracheostomy, respiratory severity score (RSS; mean airway pressure [MAP] × fraction of inspired oxygen [FiO2]), comorbidities, medication use, and the age of death. Tracheostomy patients without severe BPD were excluded. Results Despite no difference in GA, birth weight, or cardiorespiratory comorbidities, survival to discharge increased from 50 to 85% after implementation of the VCP (p < 0.05). Between period 1 and 2, there were differences in systemic and inhaled steroid use and mucolytic use. Conclusion These findings suggest an interdisciplinary approach to the care of infants with ventilator-dependent BPD can improve survival.

RATIONALE: Pulmonary hypertension (PH) is associated with poor outcomes among preterm infants with bronchopulmonary dysplasia (BPD), but whether early signs of pulmonary vascular disease are associated with the subsequent development of BPD or PH at 36 weeks post-menstrual age (PMA) is unknown. OBJECTIVES: To prospectively evaluate the relationship of early echocardiogram signs of pulmonary vascular disease in preterm infants to the subsequent development of BPD and late PH (at 36 wk PMA). METHODS: Prospectively enrolled preterm infants with birthweights 500-1,250 g underwent echocardiogram evaluations at 7 days of age (early) and 36 weeks PMA (late). Clinical and echocardiographic data were analyzed to identify early risk factors for BPD and late PH. MEASUREMENTS AND MAIN RESULTS: A total of 277 preterm infants completed echocardiogram and BPD assessments at 36 weeks PMA. The median gestational age at birth and birthweight of the infants were 27 weeks and 909 g, respectively. Early PH was identified in 42% of infants, and 14% were diagnosed with late PH. Early PH was a risk factor for increased BPD severity (relative risk, 1.12; 95% confidence interval, 1.03-1.23) and late PH (relative risk, 2.85; 95% confidence interval, 1.28-6.33). Infants with late PH had greater duration of oxygen therapy and increased mortality in the first year of life (P < 0.05). CONCLUSIONS: Early pulmonary vascular disease is associated with the development of BPD and with late PH in preterm infants. Echocardiograms at 7 days of age may be a useful tool to identify infants at high risk for BPD and PH.

OBJECTIVES: Despite improvements in survival of preterm infants, bronchopulmonary dysplasia (BPD) remains a persistent morbidity. The incidence, clinical course, and current management of severe BPD (sBPD) remain to be defined. To address these knowledge gaps, a multicenter collaborative was formed to improve outcomes in this population. STUDY DESIGN: We performed a "snapshot" in eight neonatal intensive care units (NICUs) on December 17, 2013. A standardized clinical data form for each inpatient born at < 32 weeks was completed and collated centrally for analysis. sBPD was defined as receiving ≥ 30% supplemental oxygen and/or receiving positive pressure ventilation at 36 weeks postmenstrual age (PMA). RESULTS: Of a total census of 710 inpatients, 351 infants were born at < 32 weeks and 128 of those (36.5%) met criteria for sBPD. The point prevalence of sBPD varied between centers (11-58%; p < 0.001). Among infants with sBPD there was a variation among centers in the use of mechanical ventilation at 28 days of life (p < 0.001) and at 36 weeks PMA (p = 0.001). We observed differences in the use of diuretics (p = 0.018), inhaled corticosteroids (p < 0.001), and inhaled ß-agonists (p < 0.001). CONCLUSION: The high point prevalence of sBPD and variable management among NICUs emphasizes the lack of evidence in guiding optimal care to improve long-term outcomes of this high-risk, understudied population.

PURPOSE OF REVIEW: Advances in medical therapy have increased survival of extremely premature infants and changed the pathology of bronchopulmonary dysplasia (BPD) from one of acute lung injury to a disease of disrupted lung development. With this evolution, new questions emerge regarding the molecular mechanisms that control postnatal lung development, the effect of early disruptions of postnatal lung development on long-term lung function, and the existence of endogenous mechanisms that permit lung regeneration after injury. RECENT FINDINGS: Recent data demonstrate that a significant component of alveolarization, the final stage of lung development, occurs postnatally. Further, clinical and experimental studies demonstrate that premature birth disrupts alveolarization, decreasing the gas exchange surface area of the lung and causing BPD. BPD is associated with significant short-term morbidity, and new longitudinal, clinical data demonstrate that survivors of BPD have long-standing deficits in lung function and may be at risk for the development of additional lung disease as adults. Unfortunately, current care is mainly supportive with few effective therapies that prevent or treat established BPD. These studies underscore the need to further elucidate the mechanisms that direct postnatal lung growth and develop innovative strategies to stimulate lung regeneration. SUMMARY: Despite significant improvements in the care and survival of extremely premature infants, BPD remains a major clinical problem. Although efforts should remain focused on the prevention of preterm labor and BPD, novel research aimed at promoting postnatal alveolarization offers a unique opportunity to develop effective strategies to treat established BPD.

Bronchopulmonary dysplasia (BPD) is a chronic lung disease, associated with premature birth, that arises during the infantile period. It is an evolving disease process with an unchanged incidence due to advancements in neonatal care which allow for the survival of premature infants of lower gestational ages and birth weights. Currently, there are few effective interventions to prevent BPD. However, careful attention to BPD phenotypes and comprehensive care provided by an interdisciplinary team have improved care. Interventions early in the disease course hold promise for improving long-term survival and outcomes in adulthood for this high-risk population.

INTRODUCTION: Children with tracheostomies are high risk for morbidity and mortality. Pediatric resident physicians are not routinely taught skills to care for this vulnerable patient population. Few reports link educational interventions to improved patient outcomes. This study evaluates the impact of an intensive educational training program on pediatric residents' observed skills and tracheostomy-dependent patient outcomes. METHODS: Pediatric post-graduate year 2 (PGY2) resident physicians rotating through the inpatient pediatric pulmonology month at Children's Hospital Colorado July 2018-2019 participated in the Pediatric Resident Education in Pulmonary (PREP) Boot Camp, an intensive educational program with an interactive lecture and simulation experience on patients with tracheostomy-dependence. PGY2s who partook in PREP and PGY3s who rotated before PREP initiation were invited to be studied. Primary outcomes included: (1) resident skills assessed by direct observation during simulation encounters and (2) rates of intensive care unit (ICU) transfers in tracheostomy-dependent patients following acute events before and after introduction of PREP. We hypothesized that increased education would enhance resident skills and improve patient outcomes by decreasing the rate of ICU transfers. RESULTS: PGY2 residents retained skills learned during PREP up to 11 months following initial participation, and significantly outperformed their PGY3 counterparts. There was a significant decrease in ICU transfer rate in patients with tracheostomies admitted to the pulmonary team during the 19 months following initiation of PREP. CONCLUSIONS: Enhanced early education may improve resident physicians' ability to care for complex patients with tracheostomies and could improve outcomes in this high-risk population.

Children using home invasive mechanical ventilation (HIMV), a valuable therapeutic option for chronic respiratory failure, constitute a growing population. Transitioning children using HIMV from hospital to home care is a complex process that requires a multidisciplinary approach involving healthcare professionals, caregivers, and community resources. Medical stability, caregiver competence, and home environment suitability are essential factors in determining discharge readiness. Caregiver education and training play a pivotal role in ensuring safe and effective home care. Simulation training and staged education progression are effective strategies for equipping caregivers with necessary skills. Resource limitations, inadequate home nursing support, and disparities in available community resources are common obstacles to successful HIMV discharge. International perspectives shed light on diverse healthcare systems and challenges faced by caregivers worldwide. While standardizing guidelines for HIMV discharge may be complex, collaboration among healthcare providers and the development of evidence-based regional guidelines can improve outcomes for children using HIMV and their caregivers. This review seeks to synthesize literature, provide expert guidance based on experience, and highlight components to safely discharge children using HIMV. It further assesses disparities and divergences within regional and international healthcare systems while addressing relevant ethical considerations.

This review summarizes the benefits of interdisciplinary BPD management, as well as strategies for initial programmatic development, program growth, and maintenance at centers across the United States factoring in institutional, provider, and parent reported goals that were derived from a consensus conference on BPD management.
RESUMEN
OBJECTIVE: To identify factors associated with the timing of ventilator liberation and tracheostomy decannulation among infants with severe bronchopulmonary dysplasia (sBPD) who required chronic outpatient invasive ventilation. STUDY DESIGN: Multicenter retrospective study of 154 infants with sBPD on outpatient ventilators. Factors associated with ventilator liberation and decannulation were identified using Cox regression models and multilevel survival models. RESULTS: Ventilation liberation and decannulation occurred at median ages of 27 and 49 months, respectively. Older age at transition to a portable ventilator and at discharge, higher positive end expiratory pressure, and multiple respiratory readmissions were associated with delayed ventilator liberation. Surgical management of gastroesophageal reflux was associated with later decannulation. CONCLUSIONS: Ventilator liberation timing was impacted by longer initial admissions and higher ventilator pressure support needs, whereas decannulation timing was associated with more aggressive reflux management. Variation in the timing of events was primarily due to individual-level factors, rather than center-level factors.
