Association Between Gender and Salary Among Pediatric Hospital Medicine Physicians.

OBJECTIVES: Gender-based disparities in salary exist in multiple fields of medicine. However, there is limited data examining gender inequities in salary in pediatric hospital medicine (PHM). Our primary objective was to assess whether gender-based salary differences exist in PHM. The secondary objective was to assess if, among women, the differences in salary varied on the basis of leadership positions or self-identified race and ethnicity. METHODS: We conducted a survey-based, cross-sectional study of pediatric hospitalists in December 2021. Our primary outcomes were base and total salary, adjusted for the reported number of average weekly work hours. We performed subanalyses by presence of a leadership position, as well as race. We used a weighted t test using inverse probability weighting to compare the outcomes between genders. RESULTS: A total of 559 eligible people responded to our survey (51.0%). After propensity score weighting, women's mean base salary was 87.7% of men's base (95% confidence interval [CI] 79.8%-96.4%, P < .01), and women's total salary was 85.6% of men's total (95% CI 73.2%-100.0%, P = .05) salary. On subgroup analysis of respondents with a leadership position, women's total salary was 80.6% of men's total salary (95% CI 68.7%-94.4%, P < .01). Although women who identified as white had base salaries that were 86.6% of white men's base salary (95% CI 78.5%-95.5%, P < .01), there was no gender-based difference noted between respondents that identified as nonwhite (88.4% [69.9%-111.7%] for base salary, 80.3% [57.2% to 112.7%]). CONCLUSIONS: Gender-based discrepancies in salary exists in PHM, which were increased among those with leadership roles. Continued work and advocacy are required to achieve salary equity within PHM.

Accuracy of Urinalysis for UTI in Spina Bifida.

OBJECTIVES: Urinary tract infections (UTIs) are common, but overdiagnosed, in children with spina bifida. We sought to evaluate the diagnostic test characteristics of urinalysis (UA) findings for symptomatic UTI in children with spina bifida. METHODS: Retrospective cross-sectional study using data from 2 centers from January 1, 2016, to December 31, 2021. Children with myelomeningocele aged <19 years who had paired UA (and microscopy, when available) and urine culture were included. The primary outcome was symptomatic UTI. We used generalized estimating equations to control for multiple encounters per child and calculated area under the receiver operating characteristics curve, sensitivity, and specificity for positive nitrites, pyuria (≥10 white blood cells/high-powered field), and leukocyte esterase (more than trace) for a symptomatic UTI. RESULTS: We included 974 encounters from 319 unique children, of which 120 (12.3%) met our criteria for UTI. Pyuria had the highest sensitivity while nitrites were the most specific. Comparatively, nitrites were the least sensitive and pyuria was the least specific. When the cohort was limited to children with symptoms of a UTI, pyuria remained the most sensitive parameter, whereas nitrites remained the least sensitive. Nitrites continued to be the most specific, whereas pyuria was the least specific. Among all encounters, the overall area under the receiver operating characteristics curve for all components of the UA was lower in children who use clean intermittent catheterizations compared with all others. CONCLUSIONS: Individual UA findings have moderate sensitivity (leukocyte esterase or pyuria) or specificity (nitrites) but overall poor diagnostic accuracy for symptomatic UTIs in children with spina bifida.

Factors associated with tracheostomy-associated infection treatment: A multicenter observational study.

OBJECTIVE: To characterize factors that influence the decision to treat suspected pediatric bacterial tracheostomy-associated respiratory infections (bTRAINs; e.g., pneumonia, tracheitis). METHODS: We conducted a multicenter, prospective cohort study of children with pre-existing tracheostomy hospitalized at six children's hospitals for a suspected bTRAIN (receipt of respiratory culture plus ≥1 doses of an antibiotic within 48 h). The primary predictor was respiratory culture growth categorized as Pseudomonas aeruginosa, P. aeruginosa + ≥1 other bacterium, other bacteria alone, or normal flora/no growth. Our primary outcome was bTRAIN treatment with a complete course of antibiotics as documented by the discharge team. We used logistic regression with generalized estimating equations to identify the association between our primary predictor and outcome and to identify demographic, clinical, and diagnostic testing factors associated with treatment. RESULTS: Of the 440 admissions among 289 patients meeting inclusion criteria, 307 (69.8%) had positive respiratory culture growth. Overall, 237 (53.9%) of admissions resulted in bTRAIN treatment. Relative to a negative culture, a culture positive for P. aeruginosa plus ≥1 other organism (adjusted odds ratio [aOR] 2.3; 95% confidence interval [CI] 1.02-5.0)] or ≥1 other organism alone (aOR: 2.8; 95% CI: 1.4-5.6)] was associated with treatment. Several clinical and diagnostic testing (respiratory Gram-stain and chest radiograph) findings were also associated with treatment. Positive respiratory viral testing was associated with reduced odds of treatment (aOR: 0.5; 95% CI: 0.2-0.9). CONCLUSIONS: Positive respiratory cultures as well as clinical indicators of acute illness and nonculture test results were associated with bTRAIN treatment. Clinicians may be more comfortable withholding antibiotics when a virus is identified during testing.

Gender and work-life balance: Results of a national survey of pediatric hospitalists.

In medicine, difficulty integrating work and home can lead to decreased job satisfaction, diminished well-being, and increased turnover. Understanding the experience of pediatric hospitalists can provide insights into building a stable, long-term workforce. We aim to examine gender differences in work-life balance and parental leave for physicians practicing Pediatric Hospital Medicine. METHODS: This was a cross-sectional survey study of 1096 pediatric hospitalists. Responses were collected via an online survey platform and summarized using descriptive statistics, including frequency distributions and measures of central tendency. A multivariable logistic regression was used to examine associated variables and work-life balance satisfaction. We analyzed free responses on parental leave to provide nuance to quantitative survey data. RESULTS: Five hundred and sixty-five respondents (52% response rate) completed the survey with 71% women. 343 (62%) prioritize work-life balance in career decision-making. Women report taking on more household responsibilities than their partners (41.4% vs. 8.4%; p < .001) including a larger percentage of caregiving and domestic tasks. Female gender and performing <50% caregiving were associated with decreased work-life balance satisfaction; performing <50% domestic tasks increased satisfaction. Median parental leaves were 4 weeks, with men taking significantly shorter leaves (3.5 vs. 6 weeks; p < .001) and more "paid back" time off. CONCLUSION: Work-life balance is an important factor in career decisions for men and women. Women perceive carrying a larger load at home. Qualitative results suggest that parental leave may be inadequate in length and salary support for men and women. This study adds insights into work-life integration in PHM.

Frequency of Treatment Failure of UTIs in Children With Congenital Urinary Tract Anomalies.

OBJECTIVES: Children with certain congenital anomalies of the kidney and urinary tract and neurogenic bladder (CAKUT/NGB) are at higher risk of treatment failure for urinary tract infections (UTIs) than children with normal genitourinary anatomy, but the literature describing treatment and outcomes is limited. The objectives of this study were to describe the rate of treatment failure in children with CAKUT/NGB and compare duration of antibiotics between those with and without treatment failure. METHODS: Multicenter retrospective cohort of children 0 to 17 years old with CAKUT/NGB who presented to the emergency department with fever or hypothermia and were diagnosed with UTI between 2017 and 2018. The outcome of interest was treatment failure, defined as subsequent emergency department visit or hospitalization for UTI because of the same pathogen within 30 days of the index encounter. Descriptive statistics and univariates analyses were used to compare covariates between groups. RESULTS: Of the 2014 patient encounters identified, 482 were included. Twenty-nine (6.0%) of the 482 included encounters had treatment failure. There was no difference in the mean duration of intravenous antibiotics (3.4 ± 2.5 days, 3.5 ± 2.8 days, P = .87) or total antibiotics between children with and without treatment failure (10.2 ± 3.8 days, 10.8 ± 4.0 days, P = .39) Of note, there was a higher rate of bacteremia in children with treatment failure (P = .04). CONCLUSIONS: In children with CAKUT/NGB and UTI, 6.0% of encounters had treatment failure. Duration of antibiotics was not associated with treatment failure. Larger studies are needed to assess whether bacteremia modifies the risk of treatment failure.

Frequency, Characteristics, and Outcomes of Patients Requiring Early PICU Readmission.

OBJECTIVES: Readmission to the PICU is associated with worse outcomes, but factors associated with PICU readmission within the same hospitalization remain unclear. We sought to describe the prevalence of, and identify factors associated with, early PICU readmission. METHODS: We performed a retrospective analysis of PICU admissions for patients aged 0 to 26 years in 48 tertiary care children's hospitals between January 1, 2016 and December 31, 2019 in the Pediatric Health Information System. We defined early readmission as return to the PICU within 2 calendar days of floor transfer during the same hospitalization. Generalized linear mixed models were used to analyze associations between patient and clinical variables, including complex chronic conditions (CCC) and early PICU readmission. RESULTS: The results included 389 219 PICU admissions; early PICU readmission rate was 2.5%. Factors with highest odds of early PICU readmission were CCC, with ≥4 CCCs (reference: no CCC[s]) as highest odds of readmission (adjusted odds ratio [95% confidence interval]: 4.2 [3.8-4.5]), parenteral nutrition (2.3 [2.1-2.4]), and ventriculoperitoneal shunt (1.9 [1.7-2.2]). Factors with decreased odds of PICU readmission included extracorporeal membrane oxygenation (0.4 [0.3-0.6]) and cardiopulmonary resuscitation (0.8 [0.7-0.9]). Patients with early PICU readmissions had longer overall length of stay (geometric mean [geometric SD]: 18.2 [0.9] vs 5.0 [1.1] days, P < .001) and increased odds of mortality (1.7 [1.5-1.9]). CONCLUSIONS: Although early PICU readmissions within the same hospitalization are uncommon, they are associated with significantly worse clinical outcomes. Patients with medical complexity and technology dependence are especially vulnerable.

Introduction to Dinosaurs: New Ideas from Old Bones papers honoring Peter Dodson.

This special volume of The Anatomical Record honors the life-long commitment to anatomy and paleontology by Professor Peter Dodson (Emeritus, University of Pennsylvania). Peter's legacy is not only rooted in his own research interests, but also in the wealth of former students he mentored over his career, many of whom have made their own new contributions to the fields of anatomy and paleontology through original scientific investigation. Within these 18 scientific papers, which cover multiple taxa, multiple continents, and multiple methodologies, each of the contributors brought to this volume their own unique work that can be traced back to some form of inspiration by the honoree.

Urogenital urobiome of healthy children does not differ from that of children with bladder and bowel dysfunction.

INTRODUCTION: The pediatric urinary microbiome (urobiome) has been studied in the context of healthy children and children with genitourinary pathologies including neuropathic bladder, urinary tract infection (UTI) and nephrolithiasis. Little is known about the urobiome of children with bladder and bowel dysfunction (BBD), a condition that is an established risk factor of UTI. We hypothesized that the symptoms of a child with BBD may be related to urobiome composition. OBJECTIVE: To evaluate the urogenital urobiome's role in BBD, we compared the urogenital urobiomes of children with and without BBD. STUDY DESIGN: We performed a prospective case-control pilot study at a single large, academic children's hospital. Cases included toilet trained prepubertal females over 2 years of age with BBD established through a validated scoring system and controls included asymptomatic, presumably healthy, children. Children were excluded if they had symptoms or lab work consistent with a concurrent UTI or antibiotic course for any reason within the prior 14 days. We performed 16 S ribosomal RNA gene sequencing and expanded quantitative urine culture on clean catch urine samples. To compare within sample (alpha) diversity, we used the Kruskal-Wallis test. To compare between sample (beta) diversity, we calculated the Bray-Curtis distance and performed the PERMANOVA test. RESULTS: Data from 25 children with BBD and 8 asymptomatic controls were analyzed. The demographic and clinical characteristics of the two comparison groups were similar, though a higher proportion of Black children were included in the asymptomatic control group. Neither alpha diversity nor beta diversity was significantly different between the two groups. The core microbiome of the BBD group included all the genera in the core urogenital urobiome of the controls, plus additional genera associated with opportunistic infection and/or UTI, including Escherichia, Campylobacter and Streptococcus. DISCUSSION: The results of both the 16 S sequencing and expanded quantitative urine culture in this small study suggest that the urogenital urobiomes of children with BBD do not differ significantly from those of asymptomatic children. However, the core urogenital urobiome of children with BBD included genera associated with opportunistic infection and/or UTI. This study was limited by the sample collection method ("clean catch" midstream voided urine samples, which introduce the possibility of vulvovaginal contamination), small sample size, and unequal balance of patient characteristics between the two study groups. CONCLUSION: The urogenital urobiomes of children with and without BBD do not appear to significantly differ. Larger studies are needed to confirm these findings.

Accuracy of NGAL as a Biomarker for Urinary Tract Infection in Young Febrile Children: An Individual Patient Data Meta-Analysis.

OBJECTIVE: To compare the accuracy of urine neutrophil gelatinase-associated lipocalin (NGAL) and leukocyte esterase (LE) for the diagnosis of urinary tract infection (UTI) in children. STUDY DESIGN: We performed a systematic review and individual patient data meta-analysis of studies that examined urine NGAL as a marker of UTI in children <18 years of age. We created a standardized definition of UTI and applied it to all included children. We compared sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC) of NGAL with LE. RESULTS: We included individual patient data from 3 studies for a total of 845 children. Included children had a mean age of 0.9 years (SD, 0.6 years). Using a cutoff of 32.7 ng/mL, NGAL had a sensitivity of 90.3% (95% CI: 83.2%-95.0%) and specificity of 93.7% (95% CI: 91.7%-95.4%) for the diagnosis of UTI. LE, using a cutoff of ≧ trace had a sensitivity of 81.1% (95% CI: 72.5%-87.9%) and specificity of 97.0% (95% CI: 95.4%-98.1%). The AUC for NGAL was 0.95 (95% CI: 0.92-0.98). The AUC for LE was 0.90 (95% CI: 0.86-0.93). CONCLUSION: In young, febrile children, urinary NGAL is more sensitive for the diagnosis of UTI than LE but is slightly less specific.

Equity in Receipt of a Lumbar Puncture for Febrile Infants at an Academic Center.

BACKGROUND: The evaluation of febrile infants ≤60 days of age is often guided by established protocols. However, structural racism and physicians' implicit bias may affect how such clinical guidelines are applied. OBJECTIVE: To determine the association between self-identified race, insurance type, ZIP code-based median household income (MHI) and receiving a guideline-concordant lumbar puncture (GCLP) in febrile infants. METHODS: This was a 3-year retrospective cross-sectional study of all febrile infants ≤60 days old presenting to a children's hospital from 2015 to 2017. GCLP was defined as obtaining or appropriately not obtaining a lumbar puncture as defined by the hospital's clinical practice guideline, which recommended performing a lumbar puncture for all febrile infants ≤60 days of age unless an infant was >28 days of age and had respiratory syncytial virus-positive bronchiolitis. Univariate analyses were used to identify variables associated with receiving a GCLP. Variables with a P < .1 were included in a multivariate logistic regression with race, MHI, and insurance type. RESULTS: We included 965 infants. Age (adjusted odds ratio, 0.95; 95% confidence interval, 0.94-0.97) and temperature on arrival (adjusted odds ratio, 1.36; 95% confidence interval, 1.04-1.78) were significantly associated with receipt of a GCLP. Self-identified race, insurance type, and MHI were not associated with receiving a GCLP. CONCLUSION: Receipt of a GCLP was not associated with race, MHI, or insurance type. As recent national guidelines change to increase shared decision-making, physician awareness and ongoing assessment of the role of factors such as race and socioeconomic status in the clinical evaluation and outcomes of febrile infants will be critical.

Iyuku raathi, a new iguanodontian dinosaur from the Early Cretaceous Kirkwood Formation, South Africa.

We name and describe a new iguanodontian dinosaur from the Early Creteceous Kirkwood Formation, Eastern Cape Province, South Africa. This dinosaur is one of only two ornithopod dinosaurs known from the Cretaceous of southern Africa, and is unique in being represented primarily by hatchling to young juvenile individuals as demonstrated by bone histological analysis. All of the juvenile material of this new taxon comes from a single, laterally-restricted bonebed and specimens were primarily recovered as partial to complete single elements, although rare articulated materials and one partial skeleton were found. Sedimentology of the bonebed suggests that this horizon heralds a change in environment upsection to a drier and more seasonal climate. This accumulation of bones is interpreted as seasonal mortality from a nesting site or nesting grounds and may be linked to this environmental shift.

Uromycobiome in infants and toddlers with and without urinary tract infections.

BACKGROUND: The bacterial components of the urobiome have been described in children, both with and without urinary tract infections (UTI). However, less is known about the pediatric uromycobiome: the community of fungi in the urine. The objectives of this study were to describe the uromycobiome in children and determine whether the uromycobiome differs between children with and without UTI. METHODS: This was a cross-sectional study of febrile children less than 3 years of age who presented to the Emergency Department and had a catheterized urine sample sent as part of clinical care. We obtained residual urine for use in this study and identified components of the uromyobiome through amplification and sequencing of the fungal ITS2 region. We then compared the uromycobiome between those with and without UTI. RESULTS: We included 374 children in this study (UTI = 50, no UTI = 324). Fungi were isolated from urine samples of 310 (83%) children. Fungi were identified in a higher proportion of children with UTI, compared to those without UTI (96% vs. 81%, p = 0.01). Shannon diversity index was higher in children with UTI, compared to those without (p = 0.04). Although there were differences in the most abundant taxa between children with and without UTI, there was no significant difference in beta diversity between groups. CONCLUSIONS: Fungi were detected in the majority of catheterized urine samples from children. While a higher proportion of children with UTI had fungi in their urine, compared to children without UTI, there was no difference in the composition of these groups. A higher resolution version of the Graphical abstract is available as Supplementary information.

Predictors of Empiric Antibiotic Use in the Emergency Department in Children Without Urinary Tract Infections.

OBJECTIVES: Urinary tract infections (UTIs) are a common diagnosis within the pediatric emergency department (ED). Because of the necessary delay in obtaining urine culture results, clinicians must decide whether to prescribe antibiotics for a suspected UTI before urine culture results. The primary objective of this study was to identify the proportion of children given empiric antibiotics who subsequently did not meet consensus definition of an UTI. The secondary objective was to identify factors associated with return visits to the ED after an index visit for UTI. We also attempted to identify predictors of prescription of empiric antibiotics for children who did not have a UTI. METHODS: This was a retrospective chart review of all patients between the ages of 2 months and 18 years diagnosed with a UTI between July 2016 and June 2017 in the ED of a single urban quaternary care center. Patients were excluded for the following reasons: use of bag for urine collection, subsequent admission to the hospital, receipt of antibiotics within the previous 3 days, use of antibiotics for an indication other than a UTI, and urine culture obtained at an outside facility. RESULTS: Of 404 included patients, 389 (96.2%) were discharged on antibiotics and 243 (62.4%) did not have a UTI. On the multivariate analysis, age ≧ 36 months was associated with increased odds of receiving antibiotics and not having a UTI while both ≥1+ leukocyte esterase and ≥1+ nitrites on urinalysis were associated with decreased odds of receiving antibiotics and not meeting UTI criteria. Sixty-two patients revisited the ED within 30 days of the initial visit, 24 (38.7%) of which met criteria for UTI during the index visit. Prescription of antibiotics at the time of the index visit was associated with decreased odds of reutilization, whereas an extended-spectrum ß-lactamase producing organism cultured from urine at the index visit was associated with increased odds of reutilization. CONCLUSIONS: A high number of patients discharged on empiric antibiotics did not meet criteria for a UTI. We did not identify clinically useful factors that predicted prescription of empiric antibiotics for children who do not have a UTI. We believe that unnecessary antibiotic prescriptions could be substantially decreased by decreasing empiric use of antibiotics coupled with reliable follow-up for positive urine cultures.

Computed tomographic analysis of the dental system of three Jurassic ceratopsians and implications for the evolution of tooth replacement pattern and diet in early-diverging ceratopsians.

The dental system of ceratopsids is among the most specialized structure in Dinosauria by the presence of tooth batteries and high-angled wear surfaces. However, the origin of this unique dental system is poorly understood due to a lack of relevant knowledge in early-diverging ceratopsians. Here, we study the dental system of three earliest-diverging Chinese ceratopsians: Yinlong and Hualianceratops from the early Late Jurassic of Xinjiang and Chaoyangsaurus from the Late Jurassic of Liaoning Province. By micro-computed tomographic analyses, our study has revealed significant new information regarding the dental system, including no more than five replacement teeth in each jaw quadrant; at most one replacement tooth in each alveolus; nearly full resorption of the functional tooth root; and occlusion with low-angled, concave wear facets. Yinlong displays an increase in the number of maxillary alveoli and a decrease in the number of replacement teeth during ontogeny as well as the retention of functional tooth remnants in the largest individual. Chaoyangsaurus and Hualianceratops have slightly more replacement teeth than Yinlong. In general, early-diverging ceratopsians display a relatively slow tooth replacement rate and likely use gastroliths to triturate foodstuffs. The difference in dietary strategy might have influenced the tooth replacement pattern in later-diverging ceratopsians.

Gender Distribution of Scholarship and Measures of National Recognition in Hospital Medicine.

OBJECTIVE: Our specific aim was to assess the gender distribution of aspects of scholarly productivity and professional standing for pediatric hospital medicine over a 5-year period. We also evaluated for correlation between the makeup of editorial boards, conference planning committees, and chosen content. METHODS: We reviewed scholarly publications, presentations, editorial boards, planning committees, awardees, and society leadership in pediatric hospital medicine from 2015 to 2019 and determined gender using published methods to assess for differences between observed proportions of women authors and presenters and the proportion of women in the field. RESULTS: The field of pediatric hospital medicine at large is 69% women (95% confidence internal [CI] 68%-71%), and an estimated 57% of senior members are women (95% CI 54%-60%). We evaluated 570 original science manuscripts and found 67% (95% CI 63%-71%) women first authors and 49% (95% CI 44%-53%) women senior authors. We evaluated 1093 presentations at national conferences and found 69% (95% CI 65%-72%) women presenters of submitted content and 44% (95% CI 37%-51%) women presenters of invited content. Senior authorship and invited speaking engagements demonstrated disproportionately low representation of women when compared with senior members of the field (senior authorship, P = .002; invited presenters, P < .001). Strong positive correlation between gender composition of conference planning committees and selected content was also noted (r = 0.94). CONCLUSION: Our study demonstrated representative gender distribution for some aspects of scholarly productivity in pediatric hospital medicine; however, a lack of gender parity exists in senior roles.

The pediatric urobiome in genitourinary conditions: a narrative review.

The microbial ecosystem within the bladder that can be measured within the urine, or urobiome, is an emerging field of study with little published data regarding children. However, investigations into urobiome research have the potential to significantly impact the understanding of the pathophysiology of genitourinary conditions, as well as potentially identify novel therapeutics. Therefore, both researchers and clinicians should be aware of pediatric urobiome research. The purpose of this review is to highlight the literature around urobiome research in urinary tract infections, nephrolithiasis, and neurogenic bladder; comment on pediatric-specific considerations when reading and interpreting the urobiome literature; and to identify new potential areas of research.
