Global Health Education in Pediatric Hospital Medicine Fellowships in the United States.

BACKGROUND AND OBJECTIVES: Pediatric fellows across all subspecialties are interested in global health (GH). Little is known about how GH is incorporated into Pediatric Hospital Medicine (PHM) fellowships. Our objective was to examine the current landscape of GH education in PHM fellowships. METHODS: In 2022, we conducted a cross-sectional electronic survey of PHM fellowship directors (FDs), current fellows, and recently graduated fellows (alumni) via e-mail and listservs. Surveys asked about GH education (curriculum, electives, and research) in PHM fellowships, barriers to GH training, and fellow interest in GH. RESULTS: Response rates were 56% (34/61) among PHM FDs, 57% (102/178) among fellows, and 29% (59/206) among alumni. Most fellows (73%) and alumni (59%) were interested in GH electives. Although 53% of FDs reported offering GH electives, a minority of fellows (21%) and alumni (19%) reported being offered GH electives (P <.001). Few FDs reported offering a GH curriculum (9%), although most fellows (63%) and alumni (50%) expressed interest. Of the 16 FDs without GH electives, 81% planned to offer them. Cited barriers included a lack of GH curricula, insufficient funding, competing educational demands, and a lack of international partnerships. More FDs (82%) than fellows (64%) and alumni (45%) agreed that GH education improves overall fellow education (P = .01). Similarly, more FDs (75%) than fellows (56%) and alumni (38%) agreed that offering GH education improves recruitment (P = .002). CONCLUSIONS: There is an unmet demand for GH education in PHM fellowships, and fellows may not be aware of GH opportunities.

Trends in Anthropometric Measurements of Internationally Adopted Children.

OBJECTIVE: The objective of this study was to describe anthropometric measures from internationally adopted children. Internationally adopted children are at risk for poor growth and development and there is no standardized growth chart evaluation for internationally adopted children due to variations in growth, genetics, and environmental exposures. METHODS: This is a retrospective chart review of 882 patients seen in an international adoption clinic between 2010 and 2017. Anthropometric measurements were converted to Z scores for weight, height, head circumference, and body mass index. RESULTS: A total of 41 countries and 16 subregions were represented. Central America, northern Africa, southern Africa, and southern Europe were the only subregions that had positive mean Z scores for weight, and southeast Asia had the lowest mean Z score for weight (n = 40, -1.76). No subregion had a positive mean Z score for height, and western Asia had the lowest overall mean Z score for height (n = 2, -2.44). Mean Z score for body mass index was positive in several subregions. CONCLUSIONS: Growth is an important predictor of health and development, and this study adds to the literature on growth patterns of internationally adopted children.

Gastrointestinal Microbiome Disruption and Antibiotic-Associated Diarrhea in Children Receiving Antibiotic Therapy for Community-Acquired Pneumonia.

Antibiotic-associated diarrhea (AAD) is a common side effect of antibiotics. We examined the gastrointestinal microbiota in children treated with ß-lactams for community-acquired pneumonia. Data were from 66 children (n = 198 samples), aged 6-71 months, enrolled in the SCOUT-CAP trial (NCT02891915). AAD was defined as ≥1 day of diarrhea. Stool samples were collected on study days 1, 6-10, and 19-25. Samples were analyzed using 16S ribosomal RNA gene sequencing to identify associations between patient characteristics, microbiota characteristics, and AAD (yes/no). Nineteen (29%) children developed AAD. Microbiota compositional profiles differed between AAD groups (permutational multivariate analysis of variance, P < .03) and across visits (P < .001). Children with higher baseline relative abundances of 2 Bacteroides species were less likely to experience AAD. Higher baseline abundance of Lachnospiraceae and amino acid biosynthesis pathways were associated with AAD. Children in the AAD group experienced prolonged dysbiosis (P < .05). Specific gastrointestinal microbiota profiles are associated with AAD in children.

Antibiotic Use and Outcomes in Young Children Hospitalized With Uncomplicated Community-Acquired Pneumonia.

Background: We aimed to compare children aged 36 months or younger hospitalized with uncomplicated community-acquired pneumonia (CAP) who are not treated with antibiotics to those treated with antibiotics in terms of clinical features and outcome measures. Methods: Administrative data and medical record review were used to identify patients from 3 to 36 months of age hospitalized from 2011 to 2019 with uncomplicated CAP. Patients were considered treated if they received antibiotics for >2 inpatient days and/or at discharge, and not treated if they received ≤2 inpatient days and no antibiotics at discharge. Untreated patients were compared to treated patients based on demographic features, clinical and laboratory results, and outcomes of interest, including illness severity, length of stay, and 30-day hospital readmissions. Results: Three hundred twenty-two CAP cases were included; 266 (83%) received antibiotics for >48 hours and/or at discharge. Fifty-six patients received ≤2 inpatient days of antibiotics and no antibiotics at discharge; the majority received no inpatient antibiotics. There were no differences between the 2 groups in illness severity, length of stay, or hospital readmissions. The proportion of patients treated with antibiotics decreased from 88% (2011-2013) to 66% during the most recent years studied (2017-2019). Conclusions: There was no difference in outcome of uncomplicated CAP in previously healthy children <36 months of age between those treated and not treated with antibiotics. Additional tools are needed to facilitate identification of viral CAP in young children and decrease unnecessary antibiotic use.

Short- vs Standard-Course Outpatient Antibiotic Therapy for Community-Acquired Pneumonia in Children: The SCOUT-CAP Randomized Clinical Trial.

IMPORTANCE: Childhood community-acquired pneumonia (CAP) is usually treated with 10 days of antibiotics. Shorter courses may be effective with fewer adverse effects and decreased potential for antibiotic resistance. OBJECTIVE: To compare a short (5-day) vs standard (10-day) antibiotic treatment strategy for CAP in young children. DESIGN, SETTING, AND PARTICIPANTS: Randomized double-blind placebo-controlled clinical trial in outpatient clinic, urgent care, or emergency settings in 8 US cities. A total of 380 healthy children aged 6 to 71 months with nonsevere CAP demonstrating early clinical improvement were enrolled from December 2, 2016, to December 16, 2019. Data were analyzed from January to September 2020. INTERVENTION: On day 6 of their originally prescribed therapy, participants were randomized 1:1 to receive 5 days of matching placebo or 5 additional days of the same antibiotic. MAIN OUTCOMES AND MEASURES: The primary end point was the end-of-treatment response adjusted for duration of antibiotic risk (RADAR), a composite end point that ranks each child's clinical response, resolution of symptoms, and antibiotic-associated adverse effects in an ordinal desirability of outcome ranking (DOOR). Within each DOOR rank, participants were further ranked by the number of antibiotic days, assuming that shorter antibiotic durations were more desirable. Using RADAR, the probability of a more desirable outcome was estimated for the short- vs standard-course strategy. In a subset of children, throat swabs were collected between study days 19 and 25 to quantify antibiotic resistance genes in oropharyngeal flora. RESULTS: A total of 380 children (189 randomized to short course and 191 randomized to standard course) made up the study population. The mean (SD) age was 35.7 (17.2) months, and 194 participants (51%) were male. Of the included children, 8 were Asian, 99 were Black or African American, 234 were White, 32 were multiracial, and 7 were of unknown or unreported race; 33 were Hispanic or Latino, 344 were not Hispanic or Latino, and 3 were of unknown or unreported ethnicity. There were no differences between strategies in the DOOR or its individual components. Fewer than 10% of children in either strategy had an inadequate clinical response. The short-course strategy had a 69% (95% CI, 63-75) probability of a more desirable RADAR outcome compared with the standard-course strategy. A total of 171 children were included in the resistome analysis. The median (range) number of antibiotic resistance genes per prokaryotic cell (RGPC) was significantly lower in the short-course strategy compared with the standard-course strategy for total RGPC (1.17 [0.35-2.43] vs 1.33 [0.46-11.08]; P = .01) and ß-lactamase RGPC (0.55 [0.18-1.24] vs 0.60 [0.21-2.45]; P = .03). CONCLUSIONS AND RELEVANCE: In this study, among children responding to initial treatment for outpatient CAP, a 5-day antibiotic strategy was superior to a 10-day strategy. The shortened approach resulted in similar clinical response and antibiotic-associated adverse effects, while reducing antibiotic exposure and resistance.

Do We Know Where They Go? Obtaining Travel History in Pediatric Patients.

OBJECTIVE: To determine how often travel histories are obtained in pediatric patients. METHODS: A retrospective medical record review was performed at a single tertiary care children's hospital for patients aged 2 months to 18 years who were admitted October 2015-December 2017 with International Classification of Diseases, 10th Revision codes for potential travel-related illnesses. Demographic information and travel history documentation were obtained, along with travel-related testing. From May to June 2018, prospective, single-blinded, direct observation of a convenience sample of pediatric residents was performed during the initial patient encounter to determine the frequency and quality of travel histories obtained regardless of documentation. RESULTS: Of 249 charts reviewed, 27 (10.8%) patients had a travel history query documented. Patients with complex chronic conditions were significantly less likely to have a travel history documented (37% vs 67%; P = 0.005). Age, sex, length of stay, race, payer status, and critical care admission did not significantly differ between groups. Those with a travel history documented were more likely to have a documented exposure history (100% vs 52%; P < 0.001) and additional testing performed (56% vs 13%, P < 0.001). During this time, a simulation course with residents featuring travel-related diagnoses led to a significant increase in documented travel histories (5% prior versus 21% after, P = 0.03). A total of 37 patient encounters were observed; travel history was asked for 4 times (4/37, 10.8%). CONCLUSIONS: Travel histories are rarely asked for in pediatric patients. Missed diagnoses may not only affect the patient but also have broader public health implications. Simulation is an effective tool to improve history-taking skills, yet more work is still needed.

Acute Appendicitis Associated With Multisystem Inflammatory Syndrome in Children.

Multisystem inflammatory syndrome in children (MIS-C) has been reported to cause significant gastrointestinal symptoms. In this case series, we present four patients with MIS-C with documented acute appendicitis, which strengthens the association between SARS-CoV-2, MIS-C, and acute appendicitis.

Drip System for Admissions to Resident Teams: Impact on Workload and Education.

OBJECTIVES: Assigning patients to a call team every fourth day (bolus system) caused the maldistribution of patients among resident teams and required additional faculty effort for overflow patient care. We changed to a continuous daily rotation (drip system) and examined the effect on clinical workload among resident teams, resident education, and faculty utilization. METHODS: This is a retrospective study based on the daily records of 7 am team census, the attending physician schedules for a pediatric hospital medicine service with 5 teams, and the measures of resident education, including noon conference attendance, scores on in-service examinations, and duty hour violations. Data from the bolus system (May 2014-June 2015) were compared with the drip system (May 2016-June 2017). RESULTS: Data from 348 bolus days and 338 drip days were analyzed. There was a decrease in interteam variation from 6.2 to 3.9 patients (P < 0.001). There were fewer days with the following: large interteam variation (143 to 25, P < 0.001), days with resident teams at or above capacity (26 to 11, P = 0.01), resident teams below a minimum 7 am census (133 to 18, P < 0.001), and days when additional faculty were pulled for clinical care (61 to 9, P < 0.001). Resident noon conference attendance was unchanged and there was no adverse effect on examination scores or duty hour violations. CONCLUSIONS: Changing from a bolus to a drip model for admissions to inpatient teams resulted in a more even distribution of the workload and a more efficient use of physician resources without negatively affecting resident education.

Travel Histories in Children: How Well Do Interns and Medical Students Do?

OBJECTIVE: To evaluate the knowledge of obtaining travel histories in medical students and interns. METHODS: Medical students and interns participated in a high-fidelity pediatric simulation with two cases (malaria or typhoid fever) that hinged on travel history. After the simulation, appropriate methods of obtaining travel histories were discussed. Participants completed surveys regarding their previous education and comfort with obtaining travel histories. If and how a travel history was obtained was derived from simulation observation. RESULTS: From June 2016 to July 2017, 145 medical trainees participated in 24 simulation sessions; 45% reported no prior training in obtaining travel histories. Participants asked for a travel history in all but 2 simulations; however, in 9 of 24 simulations (38%), they required prompting by either a simulation confederate or laboratory results. Participants were more comfortable diagnosing/treating conditions acquired from US domestic travel than from international travel (32.9% vs 22.4%, P < 0.001). Previous education in obtaining travel histories and past international travel did not significantly influence the level of comfort that participants felt with travel histories. CONCLUSIONS: This study highlights the lack of knowledge regarding the importance of travel histories as part of basic history taking. Medical students and interns had low levels of comfort in obtaining adequate travel histories and diagnosing conditions acquired from international travel.

Splenic infarction from vascular torsion in a child with normal splenic anatomy.

This is a case of an 8-year-old, Caucasian boy with a complex prior medical history who presented with worsening, acute, left-sided abdominal pain and fever after empiric treatment for a urinary tract infection. Repeat urinalysis was negative for infection. A renal ultrasound assessing for occult perinephric abscess or nephronia revealed normal kidneys but found a tubular structure adjacent to the left kidney. A CT scan further revealed a splenic infarction secondary to torsion. He had a surgical evaluation but was treated empirically with piperacillin/tazobactam for 10 days due to concern for infectious complications following splenic infarction. He had complete resolution of his pain and symptoms. He received routine vaccines for asplenia prior to being discharged home without any further sequelae.

Quality Improvement Project to Improve Screening for Tobacco Use in Adolescent Inpatients at a Children's Hospital.

Tobacco use begins in adolescence for the majority of smokers. The purpose of this study was to increase screening and reporting of tobacco use in hospitalized adolescents at a tertiary care children's hospital. We completed a nursing focus group to understand challenges and completed four iterative Plan-Do-Study-Act cycles, which included: (1) in-person nursing education regarding tobacco use screening, (2) addition of an e-cigarette-specific screening question, (3) the creation and dissemination of an educational video for nursing, and (4) adding the video as a mandatory component of nursing orientation. Run charts of the percentage of patients screened who reported tobacco use were created. Absolute counts of tobacco products used were also captured. From January 2016 to September 2018, 12,999 patients ≥13 years of age were admitted to the hospital. At baseline, 90.1% of patients were screened and 4.8% reported tobacco use. While the absolute number of adolescents reporting e-cigarette use increased from zero patients per month at baseline to five, the percentage of patients screened and reporting tobacco use was unchanged; the majority of e-cigarette users reported use of other tobacco products. This study demonstrates that adding e-cigarettes to screening increases reporting and suggests systems level changes are needed to improve tobacco use reporting.

Interaction energies between tetrahydrobiopterin analogues and aromatic residues in tyrosine hydroxylase and phenylalanine hydroxylase.

The phenylalanine residues 300 and 309 in the enzyme tyrosine hydroxylase are known to aid in the positioning and binding of tetrahydrobiopterin (BH4) to the enzyme active site. The residues phenylalanine 254 and tyrosine 325 similarly aid in binding BH4 in phenylalanine hydroxylase. BH4 is a cofactor necessary for enzyme function, and mutations in these residues have been shown to cause a decrease in enzyme function. We examine the pairwise interactions between each aromatic residue and BH4 using second-order Moller Plesset theory and density functional theory to determine the amount of binding due to these aromatic residues. Further, we perform in silico point mutations of these residues to determine if several likely mutations can cause a decrease in protein function. Our results show that dispersion dominates these interactions, and electrostatics alone is not enough to bind the BH4.
