RESUMEN
Pediatric pulmonology fellowship training programs are required by the Accreditation Council for Graduate Medical Education to report Pediatric Subspecialty Milestones biannually to track fellow progress. However, several issues, such as lack of subspecialty-specific context and ambiguous language, have raised concerns about their validity and applicability to use for fellow assessment and curriculum development. In this Perspective, we briefly share the process of the Pediatric Pulmonology Milestones 2.0 Work Group in creating new specialty-specific Milestones and tailoring information on the Harmonized Milestones to pediatric pulmonologists, with the goal of improving the Milestones' utility for stakeholders, including pulmonology fellows, faculty, program directors, and accrediting bodies. In addition, we created a supplemental guide to better link the Milestones to pulmonary-specific scenarios to create a shared mental model between stakeholders and remove a potential detriment to validity. Through the process, a number of guiding principles were clarified, including: 1) every Milestone should be able to be assessed independently, without overlap with other Milestones; 2) there should be clear developmental progression from one Milestone to the next; 3) Milestones should be based on the unique skills expected of pediatric pulmonologists; and 4) health equity should be a core component to highlight as a top priority to all stakeholders. In this Perspective, we describe these principles that guided formulation of the Pediatric Pulmonary Milestones to help familiarize the pediatric pulmonary community with the new Milestones. In addition, we share lessons learned and challenges in our process to inform other specialties that may soon participate in this process.
RESUMEN
Pediatric fellowship programs have conducted virtual interviews since the start of the COVID-19 pandemic in 2020. In this national survey of fellowship program directors and fellows interviewed in-person and virtually, fellowship program directors and fellows formed accurate impressions, regardless of format, but our data did not clearly support one interview format over another.

There is concern as to whether the supply of pediatric pulmonology (PULM) subspecialists will be adequate to meet future demand. As part of an American Board of Pediatrics (ABP) Foundation-sponsored supplement investigating the future of the pediatric subspecialty workforce, this article assesses the current PULM clinical workforce and estimates the clinical workforce supply in the United States through 2040. The current workforce was assessed using ABP certification and Maintenance of Certification data, and a workforce supply model evaluating population growth, clinical effort, and geographic trends was developed after incorporating ABP data. Findings demonstrate that the number of pediatric pulmonologists has gradually increased over the past decade, and the ratio of subspecialists to children is likely to increase another 20% to 40% over the next 2 decades, although absolute numbers remain small. Geographic variation in access will persist in some regions. The proportion of women in the discipline has increased, but the proportion of pediatric pulmonologists from underrepresented in medicine backgrounds still lags behind the general population. Based on current trends, the PULM clinical workforce appears equipped to meet both population growth and the modest increase in demand for clinical services speculated to occur because of changes in the subspecialty's clinical portfolio. However, several factors could inhibit growth, and geographic maldistribution may continue to impact care access. Efforts to address variation in access and demographic diversity in the field are warranted. This article concludes by discussing the training, clinical practice, policy, and future workforce research implications of the data presented.

BACKGROUND: The ACGME recently released its recommendation for updates to the program requirements for pediatrics. These updates proposed changes to allocation of resident clinical time and a greater emphasis on individualization. The potential impact of these changes on the training of physician-scientists is discussed. METHODS: Discussion of the proposed changes was held within the members of the National Pediatrician-Scientist Collaborative Workgroup, a group that represents scientists, trainees, program directors, chairs, and physician-scientist educators at nearly 30 residency programs from across the US with a focus on understanding and developing optimal approaches to physician-scientist training. Consideration was given to the both the personal and institutional impact of the proposal for physician-scientist development. RESULTS: Both threats and opportunities were identified. Key opportunities include the enhanced individualized training time that could be used to explore research. Threats include re-allocation of clinical training time that may strain institutions financially, expand clinical service requirements for other early career stage individuals, and alter exposure to a broad range of pediatric specialists and sub-specialists that impact career development. CONCLUSION: The NPSCW encourages consideration of the impact of changing program requirements on physician-scientist development to include ongoing discussion amongst mentors, programs, and trainees to understand and mitigate impact of new program requirements on the development of pediatrician-scientists.

There is growing concern that current trends in pediatric pulmonology will lead to a workforce shortage resulting in patients having difficulty accessing subspecialty care. As part of the Pediatric Pulmonology Division Directors Association and Pediatric Pulmonary Training Directors Association Workforce Summit, we examined factors affecting the recruitment of learners into pediatric pulmonary fellowship training (PPFT) programs. The goal of our workgroup was to describe these issues and develop a plan to increase the pipeline of learners who ultimately pursue PPFT. Specifically, we summarize factors that impact decisions to undertake PPFT, describe existing initiatives to enhance recruitment, and propose future strategies to increase early career learner interest.

BACKGROUND: Pulmonary physiology is a challenging, necessary component of pediatric pulmonary fellowship education. Our pediatric pulmonology fellowship program provided this education utilizing a flipped classroom approach but satisfaction with the method was declining. Evidence suggests that adult learners benefit from an engaging lecture method, but no evidence exists to compare the flipped classroom approach to the engaging lecture approach for pulmonary physiology education. OBJECTIVE: To develop the most effective physiology curriculum for pediatric pulmonary fellows by comparing the flipped classroom approach to an engaging lecture method. METHODS: Five physiology teaching sessions were assigned to the flipped classroom method and 5 to the engaging lecture style. Anonymous surveys assessing satisfaction, utilizing a five-point Likert scale, were completed by fellows at the end of each session. An unpaired t-test was used to compare responses. RESULTS: Seven pediatric pulmonary fellows enrolled in the study. The average attendance per session was 5 fellows. There was no significant difference in fellows' perceived understanding of the assigned physiology topic prior to the flipped classroom versus engaging lecture sessions. Fellows' perceived understanding of the topics improved after both session types, with significantly more improvement after the engaging lecture sessions. Fellows also reported that engaging lecture sessions were more useful and improved their test-taking confidence. They were more likely to recommend engaging lecture sessions to future pulmonary fellows. CONCLUSIONS: Pediatric pulmonary fellows benefited from the use of the engaging lecture style for physiology education.
RESUMEN
Kaposiform lymphangiomatosis is an uncommon generalized lymphatic anomaly with distinctive clinical, radiologic, histopathologic, and molecular findings. Herein, we document the pathology in 43 patients evaluated by the Boston Children's Hospital Vascular Anomalies Center from 1999 to 2020. The most frequent presentations were respiratory difficulty, hemostatic abnormalities, and a soft tissue mass. Imaging commonly revealed involvement of some combination of mediastinal, pulmonary, pleural, and pericardial compartments and most often included spleen and skeleton. Histopathology was characterized by dilated, redundant, and abnormally configured lymphatic channels typically accompanied by dispersed clusters of variably canalized, and often hemosiderotic, spindled lymphatic endothelial cells that were immunopositive for D2-40, PROX1, and CD31. An activating lesional NRAS variant was documented in 9 of 10 patients. The clinical course was typically aggressive, marked by hemorrhage, thrombocytopenia, diminished fibrinogen levels, and a mortality rate of 21%.

BACKGROUND: Lung transplantation is a therapeutic option for end-stage pediatric pulmonary hypertension (PH). Right ventricular (RV) recovery post-lung transplant in children with PH has not been well-described, and questions persist about the peri-operative course and post-transplant cardiac function after lung transplantation in medically refractory PH patients with baseline RV dysfunction. METHODS: A single-center chart review identified patients with childhood PH who subsequently underwent bilateral orthotopic lung transplantation between 2000 and 2020. Twenty-six patients met criteria; three were excluded due to echocardiograms not available for digital review. RV fractional area change (FAC) and left ventricular eccentricity index (LVEI) were determined prior to transplantation, and at 1, 3, 6, and 12-month post-transplantation. RESULTS: Fourteen of 23 patients had baseline RV dysfunction. The median age at transplantation was 16.5 years and 13.9 years for those with and without baseline RV dysfunction, respectively. Of the 14 with baseline RV dysfunction, 12 (86%) were alive 1-year post-transplantation. All patients with baseline RV dysfunction had increased RV-FAC post-transplantation with normalization of RV-FAC in 70% at 3 months and 100% of patients by 12-month post-transplantation. Duration of ventilation (p = .4), intensive care unit (p = .5), or hospital stay (p = .9) was not associated with pre-transplant RV function. CONCLUSIONS: Among pediatric patients with PH and RV dysfunction, pre-transplantation RV function was not associated with short-term outcomes. All patients with baseline RV dysfunction had improvement in RV function, justifying consideration of lung transplantation among pediatric patients with end-stage PH and RV dysfunction.

Rationale: Extracorporeal membrane oxygenation (ECMO) is increasingly used to bridge children who are wait-listed and failing conventional respiratory support for lung transplantation. Objectives: To compare in-hospital mortality and a composite outcome of 1-year mortality or retransplantation in children bridged with ECMO, supported with mechanical ventilation (MV), and given neither support. Methods: The United Network for Organ Sharing was used to analyze lung transplant recipients aged ⩽20 years from January 2004 to August 2019. Recipients were categorized according to their degree of respiratory support at the time of transplant, including ECMO, MV, or neither. Multivariable analysis was used to evaluate support type and in-hospital mortality. Results: Of 1,014 children undergoing a lung transplant, 68 (6.7%) required ECMO as a bridge to transplant, 144 (14.2%) required MV, and 802 (79.1%) required neither. Primary diagnosis in the ECMO cohort included cystic fibrosis (43%), pneumonia and/or acute respiratory distress syndrome (10.3%), interstitial pulmonary fibrosis (7.4%), and pulmonary hypertension (5.9%). The number of patients bridged with ECMO increased throughout the study period from 0% in 2004 to 16.7% in 2018. Multivariable analysis showed bridging with both ECMO (adjusted odds ratio, 3.57; 95% confidence interval, 1.42-8.97) and MV (adjusted odds ratio, 2.67; 95% confidence interval, 1.26-5.57) increased in-hospital mortality after lung transplantation. However, there was no difference in composite outcome of mortality and retransplantation at 1 year between the three groups. Conclusions: ECMO to bridge children receiving lung transplantation has increased. Despite this, ECMO is a high-risk bridge strategy for children awaiting lung transplantation. Future research should target interventions that can be focused on improving survival in these patients.

The COVID-19 pandemic will leave an indelible mark on the careers of current medical trainees. Given the disruptions to medical education, economic impact on institutions, and the uncertainties around future job prospects, trainees are facing unprecedented challenges. This situation is especially concerning for futures of pediatric physician-scientist trainees, where concerns regarding maintaining the pipeline were well documented prior to the emergence of COVID-19. In this Perspectives article, we leverage the unique expertise of our workgroup to address concerns of physician-scientist trainees and to provide suggestions on how to navigate career trajectories in the post-COVID-19 era. We identified and addressed four major areas of concern: lack of in-person conferences and the associated decrease access to mentors and networking activities, decreased academic productivity, diminished job prospects, and mental health challenges. We also suggest actions for trainees, mentors and educational leaders, and institutions to help support trainees during the pandemic, with a goal of maintaining the pediatric physician-scientist pipeline.

INTRODUCTION: Bile reflux may cause for lung allograft rejection, yet there are no studies that determine (i) the relationship between gastric and lung bile concentrations, (ii) whether bile is present in lungs of nontransplant patients, (iii) the relationship between gastric dysmotility and lung bile, (iv) the impact of reflux therapies on lung bile, and (v) whether lung bile worsens outcomes in nontransplant patients. This study will address these gaps in the literature. METHODS: We prospectively recruited lung transplant (LTX) patients and nontransplant patients with respiratory symptoms (RP) and collected paired gastric and lung samples. Bile concentration and composition of samples was assessed using liquid chromatography-mass spectrometry. Bile results were compared with clinical parameters, including the presence of esophagitis, gastric dysmotility, and/or pathologic gastroesophageal reflux. RESULTS: Seventy patients (48 RP and 22 LTX) were recruited. Overall, 100% of gastric and 98% of bronchoalveolar lavage samples contained bile. The mean gastric bile concentrations in RP and LTX patients were 280 ± 703 nmol/L and 1,004 ± 1721 nmol/L, respectively (P = 0.02). There was no difference in lung bile concentrations between RP (9 ± 30 nmol/L) and LTX (11 ± 15 nmol/L, P = 0.7). Patients with delayed gastric emptying had higher lung bile concentrations (15.5 ± 18.8 nmol/L) than patients with normal gastric emptying (4.8 ± 5.7 nmol/L, P = 0.05) independently of reflux burden. Proton pump inhibitor use increased the proportion of unconjugated gastric bile acids. High lung bile concentrations were associated with an increased risk of hospitalization and longer hospital stays in RP patients (P < 0.05). DISCUSSION: Lung bile is almost universally present in symptomatic patients, and higher concentrations are associated with poorer respiratory outcomes.

BACKGROUND: Delayed gastric emptying has been associated with increased graft rejection, although the mechanism of this association is not known. This study aims to investigate the interrelationship between delays in gastrointestinal motility and the diversity and composition of gastric, oropharyngeal, and lung microbiomes in pediatric lung transplant recipients. METHODS: We prospectively recruited 23 pediatric lung transplant recipients and 98 pediatric patients with respiratory symptoms undergoing combined endoscopy and bronchoscopy. Gastric, oropharyngeal, and bronchoalveolar lavage samples were collected for 16S sequencing. Gastric samples were also analyzed for bile composition using liquid chromatography. RESULTS: Patients who underwent lung transplantation had significantly reduced alpha diversity in gastric and oropharyngeal sites compared with patients with respiratory symptoms. This reduction in alpha diversity was especially evident in gastric samples in patients with delayed gastric emptying defined as abnormal gastric emptying on nuclear scintigraphy or as an elevation in gastric bile concentration (p ≤ 0.05). Whereas monocolonies were seen in the lungs of patients who underwent transplantation, these were not the same microbes seen in the stomach; the microbial overlap between lung and gastric samples within patients was low, and data indicated high individual variation between lung transplant recipients. Other contributors to reduced alpha diversity included antibiotics in combination with proton pump inhibitors, especially in gastric and oropharyngeal samples. CONCLUSIONS: Lung transplant recipients have reduced microbial diversity in gastric fluid (GF) and oropharynx compared with patients who did not undergo lung transplantation. The decreased alpha diversity in GF may be associated with dysmotility.
