06: LINC00402 IS A NOVEL REGULATOR OF ALLOGENEIC T CELL FUNCTION AND T CELL RECEPTOR SIGNAL TRANSDUCTION

Methods/Results: Using multiple in vitro and in vivo laboratory models as well as T cells from two independent HSCT and one cardiac transplantation cohort, we found that LINC00402 was rapidly down-regulated upon T cell activation and was preserved by inhibiting T cell activation with multiple clinically relevant small molecule inhibitors. Functionally, depletion of LINC00402 using either anti-sense oligonucleotides or electroporation of CRISPR/Cas9 ribonucleoprotein complexes inhibited the proliferation of allo-T cells. Mechanistically, LINC00402 enhanced RAS activation, MEK1/2 activation, ERK1/2 activation, c-FOS nuclear accumulation, and the expression of the ERK/c-FOS-responsive genes IL-2 and EGR-1 following T cell receptor engagement.
Conclusions: These data suggest LINC00402 expression is down-regulated by a negative feedback loop following T cell activation, it promotes allo-T cell proliferation, and it enhances a RAS-MEK-ERK-c-FOS pathway following T cell activation. Because of its T cell-specific expression and impact on allo-T cell responses, targeting LINC00402 may improve outcomes after allo-HSCT and solid organ transplantation.

Methods: We tested the association between the number of extrapulmonary organ system failures (OSFs) and levels of IL-8 and IL-1ra in children enrolled in the Genetic Variation and Biomarkers in Acute Lung Injury (BALI, R01HL095410) study, an ancillary study to the RESTORE clinical trial (U01HL086622). We hypothesized that there would be an association between elevated levels of both biomarkers and increased number of OSFs. Children with IL-8 or IL-1ra values on days 0-5 (day 0 is the day of intubation) were included in the analyses. Plasma IL-8 and IL-1ra were assayed by ELISA. Biomarker data was log transformed. Association of biomarker levels with OSFs was analyzed on days 1-4 with organ failure stratified into 0, 1, 2 and 3 or more OSFs. Univariate analysis significance was determined using the Kruskal-Wallis test. Multivariable logistic regression was adjusted for age, sepsis, race/ethnicity and severity of oxygenation defect (as measured by oxygenation index and/or oxygenation saturation index levels).
Results: 432 patients were included in the analysis. Univariate analysis indicated that increasing levels of IL-8 were associated with increasing number of OSFs on days 0-4 (p<0.05). Increasing levels of plasma IL-1ra were associated with increasing number of OSFs (1, 2 and 3 or more) on days 1-4 (p<0.05). Multivariable analyses also showed that increasing IL-8 was independently associated with increasing numbers of OSFs on days 1-4 (p<0.05) as compared to no OSFs. Multivariable analyses showed that increasing IL-1ra levels were independently associated with increased odds of 1 OSF on days 1 and 2 (p<0.05), 2 OSFs on day 2 (p=0.01), and 2 or more OSFs on days 1-4 (p<0.01) as compared to no OSFs.
Conclusions: Plasma IL-8 and IL-1ra levels are increased in pediatric patients with increasing number of OSFs on days 1-4 after acute respiratory failure. These biomarkers may be useful, if measured early and serially in the course of acute respiratory failure, in evaluating the severity of multiple organ dysfunction syndrome in critically ill children. These data also indicate the potential for targeted anti-inflammatory treatment in these patients.

24: RESPIRATORY FAILURE AND SHOCK IN A 7-MONTH-OLD BOY
Atchison C1,2, Holleran E1, Garcia A1, Chang YK1, Rappaport, L1
DISCUSSION: The differential diagnosis at presentation includes sepsis, meningoencephalitis, toxic ingestion, non-accidental trauma, inborn error of metabolism, idiopathic pulmonary hypertension, heart failure of any etiology, and pulmonary veno-occlusive disease. Additional history is notable for the patient being exclusively breastfed, with mother consuming 0.5 to 3 pounds of corn starch daily and little additional caloric intake. The patient has rapid improvement after initiation of enteral feeds with standard infant formula and with normalization of cardiac function and improved neurologic status during a 26 day admission. Thiamine level on day 12 of admission was below normal range and the diagnosis of infantile beriberi was made.
THE CONDITION: Infantile beriberi is caused by an inadequate dietary intake of thiamine. Thiamine serves important functions in oxidative energy metabolism, as well as in the production of neurotransmitters, myelin, and nucleic acids. Intracellular thiamine is an important component of the enzyme complexes of pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase, which are responsible for production of the citric acid cycle precursor acetyl-CoA and citric acid cycle component succinyl-CoA, respectively. Without these thiamine-dependent enzymes, cellular energy production shifts towards anaerobic metabolism with resulting increase in cellular pyruvate and lactate.
TREATMENT: Current literature suggests a low threshold for attempting a therapeutic thiamine challenge as a diagnostic tool in the setting of acutely ill infants with clinical concerns for deficiency, with some sources suggesting that intramuscular or slow-push intravenous thiamine infusion be part of routine resuscitation.

41: Multisystem Organ Dysfunction in the Setting of Uncontrolled Systemic Lupus Erythematosus
Alex Sliwicki, M.D.1; Leah Rappaport, M.D.2
Discussion: Systemic lupus erythematosus (SLE) is a chronic inflammatory disease that can affect multiple organ systems. Macrophage activation syndrome (MAS), which is a secondary form of hemophagocytic lymphohistiocytosis, is a rare but life-threatening complication of uncontrolled rheumatologic conditions. In this case, a patient with known rheumatologic disease presented with concerning laboratory findings consistent with multisystem organ dysfunction. The initial differential was broad and early determination of a ferritin level was vital in making the diagnosis and shifting attention from septic workup to high dose steroids. Findings consistent with MAS include fever, pancytopenia, elevated transaminases, hypertriglyceridemia, and elevated ferritin. Conclusion: While infection would certainly be high on the differential for a patient with fever and organ dysfunction, for patients with underlying rheumatologic disease Macrophage Activation Syndrome should be considered and early screening ferritin can guide diagnosis and management.

Objective. This project aimed to examine contemporary informed consent processes.
Design/Method. Members of the Societies for Pediatric Urology (SPU; n=142) and the Pediatric Endocrine Society (PES; n=115) completed an online survey in 2020 about clinical decision-making in DSD, where a section focused on informed consent. A literature review and discussion with key stakeholders generated four statements for inclusion in informed consent documents. Providers were asked to rate their level of agreement (1=Strongly Disagree; 4=Strongly Agree) for statements to be included and whether these were listed on surgical consent forms currently in use. Statements (paraphrased) included: 1) there is an on-going debate whether surgery is in the best interest of the child; 2) genital anomalies may involve multiple procedures to correct; 3) in the future, your child may disagree with their assigned gender and request surgery to reverse the current surgery; and 4) alternatives to the surgical procedure (including rejecting all surgery) have been fully explained.
Results and Conclusions. Mean (SD) agreement scores and uptake (% reporting their practices’ informed consent document includes each statement) were as follows: Ongoing debate m=3.29 (0.65), 39.5%; Multiple procedures m=3.67 (0.55), 54.6%; Gender conflict and surgical reversal m=3.30 (0.64), 38.2%; Alternatives, including no surgery, explained m=3.57 (0.56), 53.4%. Endocrinologists (m=3.55) showed greater agreement with including these statements than Urologists (m=3.38), t(234)=2.61, p=.01. In an area of healthcare where parent-proxy decision-making is contentiously debated, the discrepancy between what providers identify as desirable versus actual practice with regard to informed consent is notable.

46: VARIATIONS IN OBJECTIVE KNOWLEDGE AMONG DECISION SUPPORT PERSONS OF PATIENTS WITH EARLY STAGE BREAST CANCER
Victoria A. Wytiaz, MD, MA; Christine M. Veenstra, MD, MSHP; Sarah T. Hawley, PhD, MPH
Methods: Patients with stage 0-II breast cancer reported to Georgia and LA SEER registries in 2014-15 and their key decision support person (DSP) were surveyed separately. DSPs were asked 4 objective knowledge questions regarding breast cancer treatment with responses dichotomized into high/low knowledge. Bivariate analyses and multivariable regression models were used to assess associations between DSP knowledge and important DSP characteristics (type of DSP, age, race, education), level of DSP engagement in 3 domains of patients’ decision-making (feeling informed about decisions, extent of and satisfaction with their involvement in decisions, and being aware of patients’ values/preferences), and patient clinical factors (stage, chemotherapy receipt, radiation receipt, type of surgery).
Results: 2502 patients (68% RR) and 1203 eligible DSPs (70% RR) responded. Most DSPs were husbands or daughters. 21% were Latino, 17% were black, 20% had
Conclusions: Objective knowledge about breast cancer treatment was varied among DSPs of patients with breast cancer. Highly engaged DSPs (aware and satisfied) were more likely to have high knowledge, suggesting that involving DSPs may be an untapped mechanism for improving patients’ understanding of treatment options. These finding suggest that DSPs can play a role in improving decision quality in patients, and that interventions focused on decision-making may benefit from modules directed to DSPs as well as patients.

Objective: We aimed to examine if myeloid leukocyte profiles (monocytes and neutrophils) are associated with metabolic impairment in children and adolescents with obesity, and if sex, age, or race influence this relationship.
Methods: 282 children ages 8–17 were evaluated. Predictor variables were absolute neutrophil counts (ANC), absolute monocyte count, monocyte subtypes and C reactive protein (CRP). Outcome variables were waist circumference, fasting glucose and insulin, HOMA-IR, HbA1c(%) and lipid profiles. Pearson correlation coefficients were used to determine associations between predictor and outcome variables. Wilcoxon two-sample tests were used to evaluate differences by sex.
Results: CRP (p< 0.0001), ANC (p< 0.0018), and classical monocytes [CD14++CD16−] (p=0.05) were significantly higher in children with obesity. CRP, ANC and classical monocytes showed positive correlations with waist circumference, fasting insulin, HOMA-IR and triglycerides. CRP was positively associated with ANC (p=0.05). ANC demonstrated positive correlation with classical monocytes in patients with obesity (p<0.001). Some of these associations were influenced by sex, race, and age.
Conclusions: CRP and myeloid leukocyte populations, specifically classical (pro-inflammatory) monocytes [CD14++CD16-] and absolute neutrophil counts, are associated with metabolic impairment and cardiovascular risk factors in children with obesity, suggesting that these cells may play a critical role in metabolic disease. Race, gender and age interactions between monocytes and metabolic parameters were significant.

Samiksha Tarun1, Jessica Hoffman1, Maria Pliakas1, Julie Barrett1, and Emily Jacobson1
Methods: In March 2020, we surveyed all house officers in the University of Michigan system to assess perceptions about ED boarding. We obtained 171 responses. Of the responses, there was wide range of participants from different fields and levels of training. We received the most responses from internal medicine house officers (n=50), pediatrics (n=35) and emergency medicine (n=19). Training years from one year to greater than five years was evenly represented amongst respondents.
Results: House officers perceived that the care of boarded patients was less safe when compared to patients who were not boarded (p < 0.05). Additionally, other contributing factors identified in the survey included communication barriers, orders that are incorrectly carried out, missed medications, delays in care, and overall differences in expected management of patients among providers of boarded patients.
Conclusions: There are numerous aspects of boarding in the ED that can be improved upon amongst all providers to increase the safety of boarding.
68: ASSESSING THE ACCURACY OF CORD BLOOD CULTURES IN ASYMPTOMATIC, TERM INFANTS
S VanOmen1; A Rompca1; S Tomajko2; S Poley2; R Schumacher2
Objective: This study aimed to determine the accuracy of obtaining cord blood cultures on healthy, asymptomatic term infants on admission to this institution by assessing the false-positive rate, or contamination rate.
Methods: Cord blood cultures were obtained from 119 asymptomatic, term/near term infants from October 2018 to March 2020. All infants had no risk factors for sepsis and remained clinically stable throughout their admission. Cord blood cultures were obtained by two neonatal nurse practitioners. A standardized guideline for obtaining cultures was developed and used.
Results: Cord blood cultures from placental blood were obtained in 118 infants. There were 3 positive cord blood cultures that grew coagulase-negative Staphylococcus, Staphylococcus epidermidis, and Corynebacterium species. All three of these samples were attributed to contamination, due to the nature of the bacteria species that grew and clinical stability of infants from which they were obtained. These findings demonstrated a false-positive rate of 2.5% with 95% CI [0.005, 0.072], which is comparable to the most recent false-positive rate of peripheral blood cultures at this institution (1.5% in 2020, 1.3% in 2019, 1.39% in 2018).
Conclusion: These findings support the accuracy of obtaining blood cultures from cord blood as opposed to drawing blood from newborns on admission. This also allows for a larger blood sample to be obtained, which decreases the false-negative rate as well. These cord blood cultures obtained on healthy, term infants can be used to establish a control rate, with further studies on obtaining cord blood cultures from premature and unstable infants. Use of cord blood for admission labs in these infants has the potential to reduce the amount of blood loss and minimize blood transfusions, which have been associated with decreased risk of intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis and death2.
