A national virtual job search series for neonatal-perinatal medicine fellows.

BACKGROUND: A standardized approach to prepare trainees for the job search has not been described. The objective of this study was to describe and evaluate an educational series on the job search for Neonatal-Perinatal Medicine (NPM) fellows and identify participants' job search knowledge gaps. METHODS: During the 2020-2021 academic year, we created a virtual, seven-part job search series for NPM fellows that required no funding. The series has been repeated annually. We use REDCap surveys to register participants, collect baseline/demographic information, and evaluate the series' impact at the beginning and end of the job search timeline. RESULTS: In the 2021-2022 academic year, 290 individuals registered for the series, and 89% completed the baseline/demographic survey. The majority were NPM fellows (89%). Early career neonatologists, NPM hospitalists, and pediatric residents also utilized the series (11%). Less than 25% reported being "knowledgeable" or "very knowledgeable" of core job search components, including the timeline of the job search, contract negotiation, and the general roles and responsibilities of junior faculty. Of those who completed the final job search survey and underwent a job search (60%, 97 of 162), the majority (86%) felt that career planning during training was stressful and believed that job search preparation should be structured into the NPM fellowship curriculum (81%). Many felt that the Job Search Series was helpful in elucidating components of the job search. CONCLUSIONS: We identified several knowledge gaps in NPM fellows' understanding of how to find, prepare for, and negotiate their first post-training job. We strongly believe these knowledge gaps are not unique to NPM fellows and that all graduate medical education trainees would benefit from a similar, easy-to-implement, no-cost series.

Acute kidney injury decreases pulmonary vascular growth and alveolarization in neonatal rat pups.

BACKGROUND: Acute kidney injury (AKI) is common in sick neonates and associated with poor pulmonary outcomes, however, the mechanisms responsible remain unknown. We present two novel neonatal rodent models of AKI to investigate the pulmonary effects of AKI. METHODS: In rat pups, AKI was induced surgically via bilateral ischemia-reperfusion injury (bIRI) or pharmacologically using aristolochic acid (AA). AKI was confirmed with plasma blood urea nitrogen and creatinine measurements and kidney injury molecule-1 staining on renal immunohistochemistry. Lung morphometrics were quantified with radial alveolar count and mean linear intercept, and angiogenesis investigated by pulmonary vessel density (PVD) and vascular endothelial growth factor (VEGF) protein expression. For the surgical model, bIRI, sham, and non-surgical pups were compared. For the pharmacologic model, AA pups were compared to vehicle controls. RESULTS: AKI occurred in bIRI and AA pups, and they demonstrated decreased alveolarization, PVD, and VEGF protein expression compared controls. Sham pups did not experience AKI, however, demonstrated decreased alveolarization, PVD, and VEGF protein expression compared to controls. CONCLUSION: Pharmacologic AKI and surgery in neonatal rat pups, with or without AKI, decreased alveolarization and angiogenesis, producing a bronchopulmonary dysplasia phenotype. These models provide a framework for elucidating the relationship between AKI and adverse pulmonary outcomes. IMPACT: There are no published neonatal rodent models investigating the pulmonary effects after neonatal acute kidney injury, despite known clinical associations. We present two novel neonatal rodent models of acute kidney injury to study the impact of acute kidney injury on the developing lung. We demonstrate the pulmonary effects of both ischemia-reperfusion injury and nephrotoxin-induced AKI on the developing lung, with decreased alveolarization and angiogenesis, mimicking the lung phenotype of bronchopulmonary dysplasia. Neonatal rodent models of acute kidney injury provide opportunities to study mechanisms of kidney-lung crosstalk and novel therapeutics in the context of acute kidney injury in a premature infant.

Risk factors for acute kidney injury in neonates with congenital diaphragmatic hernia.

OBJECTIVE: To examine incidence of acute kidney injury (AKI), antenatal and postnatal predictors, and impact of AKI on outcomes in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: Single center retrospective study of 90 CDH infants from 2009-2017. Baseline characteristics, CDH severity, possible AKI predictors, and clinical outcomes were compared between infants with and without AKI. RESULT: In total, 38% of infants developed AKI, 44% stage 1, 29% stage 2, 27% stage 3. Lower antenatal lung volumes and liver herniation were associated with AKI. Extracorporeal life support (ECLS), diuretics, abdominal closure surgery, hypotension, and elevated plasma free hemoglobin were associated with AKI. Overall survival was 79%, 47% with AKI, and 35% with AKI on ECLS. AKI is associated with increased mechanical ventilation duration and length of stay. CONCLUSION: AKI is common among CDH infants and associated with adverse outcomes. Standardized care bundles addressing AKI risk factors may reduce AKI incidence and severity.

Improving the Transition of Intravenous to Enteral Antibiotics in Pediatric Patients with Pneumonia or Skin and Soft Tissue Infections.

BACKGROUND: Despite national recommendations for early transition to enteral antimicrobials, practice variability has existed at our hospital. OBJECTIVE: The aim of this study was to increase the proportion of enterally administered antibiotic doses for Pediatric Hospital Medicine patients aged >60 days admitted for uncomplicated community-acquired pneumonia or skin and soft tissue infections from 44% to 75% in eight months. METHODS: This quality improvement study was conducted at a large, urban, academic children's hospital. The study population included Hospital Medicine patients aged >60 days with diagnoses of pneumonia or skin and soft tissue infections. Interventions included education on intravenous and enteral antibiotic charge differentials, documentation of transition plan, structured discussions of transition criteria, and real-time identification of failures with feedback. Our process measure was the total number of enteral antibiotic doses divided by all antibiotic doses in patients receiving enteral medications on the same day. An annotated statistical process control chart tracked the impact of interventions on the administration route of antibiotic doses over time. Additional outcome measures included antimicrobial costs per patient encounter using average wholesale prices and length of stay. RESULTS: The percentage of enterally administered antibiotic doses increased from 44% to 80% within eight months. Antimicrobial costs per patient encounter and the associated standard deviation of costs for our target diagnoses decreased by 70% and 84%, respectively. Average length of stay did not change. CONCLUSIONS: Standardized communication about criteria for transition from intravenous to enteral antibiotics can lead to earlier transitions for patients with pneumonia or skin and soft tissue infections, subsequently reducing costs and prescribing variability.

Improving the Readability of Pediatric Hospital Medicine Discharge Instructions.

BACKGROUND: Readable discharge instructions may help caregivers understand and implement care plans following hospitalization. Many caregivers of hospitalized children, however, have limited literacy. We aimed to increase the percentage of discharge instructions written at 7th grade level or lower for hospital medicine patients from 13% to 80% in 6 months. METHODS: Quality improvement efforts targeted a 42-bed unit at the community satellite of our large, urban academic hospital. A multidisciplinary team of physicians, nurses, and parents focused on key drivers: family engagement in discharge process, standardization of discharge instructions, staff engagement in discharge preparedness, and audit and feedback of data. Improvement cycles included 1) education and implementation of a general discharge instruction template in the electronic health record (EHR); 2) visible reminders and tips for writing readable discharge instructions; 3) implementation of disease-specific discharge instruction templates in the EHR; and 4) individualized feedback to staff on readability and content of their written discharge instructions. Instructions were individually scored for readability using an online platform. An annotated control chart assessed the impact of interventions over time. RESULTS: Through sequential interventions over 6 months, the percentage of discharge instructions written at 7th grade or lower readability level increased from 13% to 98% and has been sustained for 4 months. The reliable use of the EHR templates was associated with our largest improvements. CONCLUSION: Use of standardized discharge instruction templates and rapid feedback to staff improved the readability of instructions. Next steps include adaptation and spread to other patient populations.

Validation of Patient-Reported Outcomes Measurement Information System Short Forms for Use in Childhood-Onset Systemic Lupus Erythematosus.

OBJECTIVE: To validate the pediatric Patient-Reported Outcomes Measurement Information System short forms (PROMIS-SFs) in childhood-onset systemic lupus erythematosus (SLE) in a clinical setting. METHODS: At 3 study visits, childhood-onset SLE patients completed the PROMIS-SFs (anger, anxiety, depressive symptoms, fatigue, physical function-mobility, physical function-upper extremity, pain interference, and peer relationships) using the PROMIS assessment center, and health-related quality of life (HRQoL) legacy measures (Pediatric Quality of Life Inventory, Childhood Health Assessment Questionnaire, Simple Measure of Impact of Lupus Erythematosus in Youngsters [SMILEY], and visual analog scales [VAS] of pain and well-being). Physicians rated childhood-onset SLE activity on a VAS and completed the Systemic Lupus Erythematosus Disease Activity Index 2000. Using a global rating scale of change (GRC) between study visits, physicians rated change of childhood-onset SLE activity (GRC-MD1: better/same/worse) and change of patient overall health (GRC-MD2: better/same/worse). Questionnaire scores were compared in support of validity and responsiveness to change (external standards: GRC-MD1, GRC-MD2). RESULTS: In this population-based cohort (n = 100) with a mean age of 15.8 years (range 10-20 years), the PROMIS-SFs were completed in less than 5 minutes in a clinical setting. The PROMIS-SF scores correlated at least moderately (Pearson's r ≥ 0.5) with those of legacy HRQoL measures, except for the SMILEY. Measures of childhood-onset SLE activity did not correlate with the PROMIS-SFs. Responsiveness to change of the PROMIS-SFs was supported by path, mixed-model, and correlation analyses. CONCLUSION: To assess HRQoL in childhood-onset SLE, the PROMIS-SFs demonstrated feasibility, internal consistency, construct validity, and responsiveness to change in a clinical setting.

Neomycin and carbodiimide crosslinking as an alternative to glutaraldehyde for enhanced durability of bioprosthetic heart valves.

Glutaraldehyde cross-linked porcine aortic valves, referred to as bioprosthetic heart valves (BHVs), are often used in heart valve replacements. Glutaraldehyde does not stabilize glycosaminoglycans (GAGs) and they are lost during preparation, in vivo implantation, cyclic fatigue, and storage. We report that binding of neomycin, a hyaluronidase inhibitor, to the tissues with carbodiimide cross-linking improves GAG retention without reducing collagen and elastin stability. It also led to improved biomechanical properties. Neomycin carbodiimide cross-linking did not significantly reduce calcification in a rat subdermal implantation model when they were stored in formaldehyde after cross-linking. Removal of formaldehyde storage significantly reduced calcification.
