Identifying Gender and Racial Bias in Pediatric Fellowship Letters of Recommendation: Do Word Choices Influence Interview Decisions?

OBJECTIVES: To describe linguistic differences in letters of recommendation (LORs) for pediatric fellowship candidates based on applicant and letter writer demographics and to examine if these differences influenced the decision to interview a candidate for a fellowship position. STUDY DESIGN: LORs for applicants to 8 pediatric subspecialty fellowships at a single academic center from the 2020 Match were analyzed in this cross-sectional study. Frequency of validated agentic and communal terms in each letter were determined by a language processing web application. Bias was determined as having a >5% surplus of agentic or communal terms. RESULTS: We analyzed 1521 LORs from 409 applicants: 69% were women, 28% were under-represented minorities in medicine (URM), and 50% were invited to interview. Overall, 66% of LORs were agentic biased, 16% communal biased, and 19% neutral. There was no difference in bias in LORs by an applicant's gender (woman 67% agentic vs man 62% agentic; P = .058), race, or ethnicity (non-URM 65% agentic vs URM 67% agentic; P = .660). Despite a lower frequency of agentic terms in LORs for applicants invited for interviews, when accounting for other components of an application and applicant demographics, no significant association was made between language bias in LORs and fellowship interview status. CONCLUSIONS: The frequency of agentic and communal terms in LORs for pediatric subspecialty fellowship candidates were not found to influence the decision to invite a candidate to interview. However, raising awareness of potential areas of bias within the pediatric fellowship selection process might lead to a more equitable and holistic approach to application review.

T-Cell Receptor Excision Circles in Newborns with Congenital Heart Disease.

OBJECTIVES: To determine if children with congenital heart disease (CHD) have lower newborn T-cell receptor excision circles (TREC) levels than the general population and to evaluate if low TREC levels in newborns with CHD are associated with clinical complications such as hospitalization for infection. STUDY DESIGN: The Connecticut Newborn Screening Program reported TREC levels for newborns with CHD delivered between October 2011 and September 2016 at 2 major Connecticut children's hospitals. TREC levels for children with CHD were compared with the general population. TREC levels and outcome measures, including hospitalization for infection, were compared. RESULTS: We enrolled 575 participants with CHD in the study. The median TREC level for newborns with CHD was lower than the general population (180.1 copies/µL vs 312.5 copies/µL; P < .01). patients with CHD requiring hospitalization for infection had lower median TREC levels than their counterparts (143.0 copies/µL vs 186.7 copies/µL; P < .01). The combination of prematurity and low TREC level had a strong relationship to hospitalization for infection (area under the receiver operative characteristic curve of 0.89). There was no association between TREC level and CHD severity. CONCLUSIONS: Newborns with CHD demonstrated lower TREC levels than the general population. Low TREC levels were associated with hospitalization for infection in preterm children with CHD. Study limitations include that this was a retrospective chart review. These findings may help to identify newborns with CHD at highest risk for infection, allowing for potential opportunities for intervention.

Hypercalcemia in Patients with Williams-Beuren Syndrome.

OBJECTIVE: To evaluate the timing, trajectory, and implications of hypercalcemia in Williams-Beuren syndrome (WBS) through a multicenter retrospective study. STUDY DESIGN: Data on plasma calcium levels from 232 subjects with WBS aged 0-67.1 years were compared with that in controls and also with available normative data. Association testing was used to identify relevant comorbidities. RESULTS: On average, individuals with WBS had higher plasma calcium levels than controls, but 86.7% of values were normal. Nonpediatric laboratories overreport hypercalcemia in small children. When pediatric reference intervals were applied, the occurrence of hypercalcemia dropped by 51% in infants and by 38% in toddlers. Across all ages, 6.1% of the subjects had actionable hypercalcemia. In children, actionable hypercalcemia was seen in those aged 5-25 months. In older individuals, actionable hypercalcemia was often secondary to another disease process. Evidence of dehydration, hypercalciuria, and nephrocalcinosis were common in both groups. Future hypercalcemia could not be reliably predicted by screening calcium levels. A subgroup analysis of 91 subjects found no associations between hypercalcemia and cardiovascular disease, gastrointestinal complaints, or renal anomalies. Analyses of electrogradiography data showed an inverse correlation of calcium concentration with corrected QT interval, but no acute life-threatening events were reported. CONCLUSIONS: Actionable hypercalcemia in patients with WBS occurs infrequently. Although irritability and lethargy were commonly reported, no mortality or acute life-threatening events were associated with hypercalcemia and the only statistically associated morbidities were dehydration, hypercalciuria, and nephrocalcinosis.
