Objective: Couplet care is an innovative approach to provide postpartum care in the neonatal intensive care unit (NICU) with little known about its impact on infant feeding outcomes and maternal stress. Study design: We compared breastfeeding outcomes and maternal NICU-related stress among mother-infant dyads based on exposure to couplet care in a prospective cohort study. Result: Among 19 couplet-care exposed (CCE) dyads and 19 traditional postpartum care dyads, CCE mothers had lower self-reported stress related to parent-infant relationship as compared to traditional care (P< 0.001). CCE infants received relatively more feeds at the breast (P< 0.001), more breastmilk feeds (P= 0.002), and fewer feeds by staff (P< 0.001). Adjusted for gestational age, marital status, and infant length of stay, couplet care was associated with being in a higher tertile of percent breastmilk feeds (aOR 7.29, 95% CI 1.45–36.65). Conclusion: NICU couplet care was associated with improved parental stress and breastfeeding outcomes during hospitalization.

Egg allergy is common and caused by sensitization to ovomucoid and/or ovalbumin. Many egg-allergic patients are able to tolerate eggs baked into other foods, such as muffins. Although heating egg extensively reduces allergens, the effect of other food ingredients on allergenicity of eggs, or the “matrix effect,” is less well studied.

Although efficacy, safety, and quality of life measures associated with peanut oral immunotherapy (OIT) have been studied, the relationship between peanut OIT and clinical anxiety has not yet been evaluated. The latter is important to help providers and families have an improved shared medical decision discussion around the benefits of initiating OIT.

Introduction:Seventy percent of countries follow the World Health Organization International Code of Marketing Breast Milk Substitutes that prohibits infant formula companies (IFC) from providing free products to health care facilities, providing gifts to health care staff, or sponsoring meetings. The United States rejects this code, which may impact breastfeeding rates in certain areas.Objective:We aimed at gathering exploratory data about interactions between IFC and pediatricians.Methods:We distributed an electronic survey to U.S. pediatricians asking about practice demographics, interactions with IFC, and breastfeeding practices. Using the zip code of the practice, we obtained additional information from the 2018 American Communities Survey, including median income, percent of mothers who had graduated college, percent of mothers working, and racial and ethnic identity. We compared demographic data for those pediatricians who had a formula company representative visit versus not and those who had a sponsored meal versus not.Results:Of 200 participants, the majority reported a formula company representative visit to their clinic (85.5%) and receiving free formula samples (90%). Representatives were more likely to visit areas with higher-income patients (median = $100K versus $60K, p< 0.001). They tended to visit and sponsor meals for pediatricians at private practices and in suburban areas. Most of the reported conferences attended (64%) were formula company-sponsored.Conclusion:Interactions between IFC and pediatricians are prevalent and occur in many forms. Future studies may reveal whether these interactions influence the advice of pediatricians or the behavior of mothers who had planned to exclusively breastfeed.

We examined weight loss patterns and feeding practices of infants hospitalized for neonatal opioid withdrawal syndrome (NOWS) managed by the eat, sleep, console approach, which emphasizes nonpharmacologic treatment. Although feeding practices during hospitalization vary widely, weight loss patterns for infants managed under this approach have not yet been described.Of 744 infants with NOWS born from 2014 to 2019 at our institution, 330 met inclusion criteria (≥35 weeks’ gestation and no NICU transfer). We examined maximum weight loss and created weight loss percentile curves by delivery type using mixed effects quantile modeling with spline effect for hour of life; 95% confidence intervals (CI) were compared to published early weight loss nomograms.In the cohort, the mean gestational age was 39.2 weeks, mean birth weight was 3.1 kg, and mean length of stay was 6.5 days; 94.6% did not require pharmacologic treatment. Median percent weight loss was significantly more compared to early weight loss nomograms for both vaginally-delivered infants at 48 hours (6.9% [95% CI: 5.8–8.5] vs 2.9%) and cesarean-delivered infants at 48 hours (6.5% [95% CI: 4.1–9.1] vs 3.7%) and 72 hours (7.2% [95%CI 4.7–9.9] vs 3.5%), all P < .001. Overall, 27.9% lost >10% birth weight.We demonstrate weight loss patterns of infants with NOWS managed by the eat, sleep, console approach at a single center. Infants with NOWS lose significantly more weight than nonopioid exposed infants and are at increased risk of morbidity and health care use. Studies to address optimal feeding methods in these infants are warranted.

Throughout the COVID-19 pandemic, there has been an increase in hospital admissions for adolescents with eating disorders (EDs). However, there is a paucity of information on how this increase has affected hospitalization courses and disposition planning. We sought to describe the changes in hospitalizations for EDs at our institution during the pandemic.We reviewed charts of patients admitted to our academic medical center for nutritional restoration from January 1, 2017, to June 30, 2021. We report differences in patient characteristics and hospitalization courses using descriptive statistics and Poisson regression.We reviewed charts for 85 patients for 108 hospital admissions. Admissions increased from 1.4 per month prepandemic to 3.6 per month during the pandemic (P < .001). Most patients were female (91%), White (79%), had private insurance, (80%) and had restrictive eating behaviors (97%). During the pandemic, we found (1) an increase in the average length of stay (12.6 days vs. 18.0 days) with younger age associated with longer length of stay (P < .001); (2) more patients requiring psychotropic medication management (11% vs 31%, P = .01); and (3) fewer patients discharged from the hospital with outpatient therapy (43% vs 24%, P = .03).In addition to an increase in hospital admissions for ED management during the pandemic, our study highlights the evolving needs of ED patients during their hospitalizations. The implications of longer admissions with higher acuity at discharge represent areas where appropriate adaptations in inpatient management and disposition planning may improve the quality of care for ED patients.

Despite a practice management guideline and risk prediction model for venous thromboembolism (VTE), pediatric-specific evidence on pharmacologic prophylaxis is lacking. In a retrospective study, we characterized receipt of prophylaxis and explored its effectiveness in hospitalized injured patients below 18 years old using data from the Trauma Quality Improvement Program. Concordance of receipt of prophylaxis with guideline and predicted risk of VTE was estimated using κ statistic. Effectiveness was explored using cohorts matched based on the risk prediction model. A total of 11,165 (6.2%) of 180,932 patients received prophylaxis. Those who received prophylaxis were more commonly post-pubertal and more severely injured. Receipt of prophylaxis was fairly concordant with the guideline (κ=0.32) and predicted risk of VTE (κ=0.29). Receipt of prophylaxis was associated with higher rates of VTE likely due to confounding by indication. Low molecular weight heparin seemed more effective against VTE than unfractionated heparin (incidence rate ratio: 0.52; 95% confidence interval: 0.36, 0.75), but less effective when received ≥72 hours after admission to the hospital. We showed that hospitalized injured children did not commonly receive prophylaxis. We also showed that prophylaxis may be effective in hospitalized injured children, but it needs to be proven definitively in a randomized clinical trial.

Mistreatment of health care providers (HCPs) is associated with burnout and lower-quality patient care, but mistreatment by patients and family members is underreported. We hypothesized that an organizational strategy that includes training, safety incident reporting, and a response protocol would increase HCP knowledge, self-efficacy, and reporting of mistreatment.In this single-center, serial, cross-sectional study, we sent an anonymous survey to HCPs before and after the intervention at a 213-bed tertiary care university children’s hospital between 2018 and 2019. We used multivariable logistic regression to examine the effect of training on the outcomes of interest and whether this association was moderated by staff role.We received 309 baseline surveys from 72 faculty, 191 nurses, and 46 residents, representing 39.1%, 27.1%, and 59.7%, respectively, of eligible HCPs. Verbal threats from patients or family members were reported by 214 (69.5%) HCPs. Offensive behavior was most commonly based on provider age (85, 28.5%), gender (85, 28.5%), ethnicity or race (55, 18.5%), and appearance (43, 14.6%) but varied by role. HCPs who received training had a higher odds of reporting knowledge, self-efficacy, and experiencing offensive behavior. Incident reporting of mistreatment increased threefold after the intervention.We report an effective organizational approach to address mistreatment of HCPs by patients and family members. Our approach capitalizes on existing patient safety culture and systems that can be adopted by other institutions to address all forms of mistreatment, including those committed by other HCPs.

We updated our findings on the epidemiology of clinically relevant bleeding (CRB) in critically ill children. We also determined the concordance of CRB as defined by the International Society of Thrombosis and Haemostasis, i.e., ISTH definition, and characteristics identified by pediatric intensivists in a recent survey, i.e., survey definition.

Objective: To develop a novel, rapid, and more accurate model for estimating umbilical arterial (UAC) and venous catheter (UVC) insertion length. Study design: We evaluated UACs and UVCs from a retrospective cohort to determine the rate of correct initial positioning based on conventional birth weight-based equations utilized in our neonatal intensive care unit. We then derived new equations, developed the mobile application, UmbiCalc, to simplify implementation of the new equations, and validated their accuracy with prospective utilization. Results: The conventional equations successfully predicted insertion length in 69% (364 of 524) of UACs and only 36% (194 of 544) of UVCs. Our new model was prospectively applied to 68 UAC and 80 UVC placements with successful initial positioning achieved in 90% [95% CI, 80.2–94.9] and 76% [95% CI, 65.9–84.2], respectively. Conclusions: Our novel approach more accurately estimates UAC and UVC insertion length.

Infant formula in the United States is highly regulated. The American Academy of Pediatrics (AAP) has reported concerns over the use of non-Food and Drug Administration (FDA)-registered imported infant formulas. The purpose of this study is to identify Internet purchased and recommended imported European infant formulas and compare them with FDA labeling and nutrient requirements. We searched “European infant formulas” in Google and DuckDuckGo to identify vendors of European formulas and blogs discussing these formulas to determine the most frequently purchased and recommended brands. We then compared the identified European formula's label and listed nutrients to FDA labeling and nutrient requirements. Thirteen of 18 vendors responded to our inquiry of their top selling formula and 17 blogs were reviewed. Sixteen formulas were identified. None met all FDA label requirements. Listed nutrients fell within FDA requirements in 15 of 16 formulas. Non-FDA-registered imported European formulas do not meet all FDA-labeling requirements. Although linoleic acid, which was not listed on all of the European formulas, could not be evaluated, all formulas except one met the remaining FDA nutrient requirements. These European infant formulas are being imported into the United States via third party vendors and are not FDA-regulated, limiting the notable consumer protections set by the FDA that ensure infant formula safety. Pediatric gastroenterologists and healthcare providers need to understand the composition, labelling and lack of FDA regulation and safety concerns of these formulas in order to better counsel parents.

Type 2 diabetes is preceded by a prediabetic stage of impaired glucose tolerance that affects 10–23% of youth and is expected to double over the next decade. The natural history of impaired glucose tolerance and the determinants of β-cell dynamic response have never been investigated longitudinally in young people. We aimed to investigate the clinical and metabolic determinants of longitudinal glucose tolerance changes and β-cell function in a multiethnic cohort of obese youth.

Trans‐catheter (TC) pulmonary valve replacement (PVR) has become common practice for patients with right ventricular outflow tract obstruction (RVOTO) and/or pulmonic insufficiency (PI). Our aim was to compare PVR and right ventricular (RV) function of patients who received TC vs surgical PVR. Retrospective review of echocardiograms obtained at three time points: before, immediately after PVR, and most recent. Sixty‐two patients (median age 19 years, median follow‐up 25 months) following TC (N = 32) or surgical (N = 30) PVR at Yale‐New Haven Hospital were included. Pulmonary valve and right ventricular function before, immediately after, and most recently after PVR. At baseline, the TC group had predominant RVOTO (74% vs 10%, P< .001), and moderate‐severe PI was less common (61% vs 100%, P< .001). Immediate post‐procedural PVR function was good throughout. At last follow‐up, the TC group had preserved valve function, but the surgical group did not (moderate RVOTO: 6% vs 41%, P< .001; >mild PI: 0% vs 24%, P= .003). Patients younger than 17 years at surgical PVR had the highest risk of developing PVR dysfunction, while PVR function in follow‐up was similar in adults. Looking at RV size and function, both groups had a decline in RV size following PVR. However, while RV function remained stable in the TC group, there was a transient postoperative decline in the surgical group. TC PVR in patients age <17 years is associated with better PVR function in follow‐up compared to surgical valves. There was a transient decline in RV function following surgical but not TC PVR. TC PVR should therefore be the first choice in children who are considered for PVR, whenever possible.

AbstractBackgroundIt is unclear which pediatric disaster triage (PDT) strategy yields the best accuracy or best patient outcomes.MethodsWe conducted a cross-sectional analysis on a sample of emergency medical services providers from a prospective cohort study comparing the accuracy and triage outcomes for 2 PDT strategies (Smart and JumpSTART) and clinical decision-making (CDM) with no algorithm. Participants were divided into cohorts by triage strategy. We presented 10-victim, multi-modal disaster simulations. A Delphi method determined patients’ expected triage levels. We compared triage accuracy overall and for each triage level (RED/Immediate, YELLOW/Delayed, GREEN/Ambulatory, BLACK/Deceased).ResultsThere were 273 participants (71 JumpSTART, 122 Smart, and 81 CDM). There was no significant difference between Smart triage and CDM. When JumpSTART triage was used, there was greater accuracy than with either Smart (P<0.001; OR [odds ratio]: 2.03; interquartile range [IQR]: 1.30, 3.17) or CDM (P=0.02; OR: 1.76; IQR: 1.10, 2.82). JumpSTART outperformed Smart for RED patients (P=0.05; OR: 1.48; IQR: 1.01,2.17), and outperformed both Smart (P<0.001; OR: 3.22; IQR: 1.78,5.88) and CDM (P<0.001; OR: 2.86; IQR: 1.53,5.26) for YELLOW patients. Furthermore, JumpSTART outperformed CDM for BLACK patients (P=0.01; OR: 5.55; IQR: 1.47, 20.0).ConclusionOur simulation-based comparison suggested that JumpSTART triage outperforms both Smart and CDM. JumpSTART outperformed Smart for RED patients and CDM for BLACK patients. For YELLOW patients, JumpSTART yielded more accurate triage results than did Smart triage or CDM.

ImmunoglobulinA (IgA) is the predominant antibody isotype in the gut, where it regulates commensal flora and neutralizes toxins and pathogens. The function of food-specific IgA in the gut is unknown but is presumed to protect from food allergy. Specifically, it has been hypothesized that food-specific IgA binds ingested allergens and promotes tolerance by immune exclusion; however, the evidence to support this hypothesis is indirect and mixed. Although it is known that healthy adults have peanut-specific IgA in the gut, it is unclear whether children also have gut peanut-specific IgA. We found in a cohort of non–food-allergic infants (n= 112) that there is detectable stool peanut-specific IgA that is similar to adult quantities of gut peanut-specific IgA. To investigate whether this peanut-specific IgA is associated with peanut tolerance, we examined a separate cohort of atopic children (n= 441) and found that gut peanut-specific IgA does not predict protection from development of future peanut allergy in infants nor does it correlate with concurrent oral tolerance of peanut in older children. We observed higher plasma peanut-specific IgA in those with peanut allergy. Similarly, egg white–specific IgA was detectable in infant stools and did not predict egg tolerance or outgrowth of egg allergy. Bead-based epitope assay analysis of gut peanut-specific IgA revealed similar epitope specificity between children with peanut allergy and those without; however, gut peanut-specific IgA and plasma peanut-specific IgE had different epitope specificities. These findings call into question the presumed protective role of food-specific IgA in food allergy.

Potential vitamin D–related influences on inflammatory diseases such as asthma are controversial, including the suggestion that vitamin D insufficiency is associated with increased asthma morbidity. Vitamin D–binding protein transports vitamin D metabolites in the circulation. Single nucleotide polymorphisms in the GCgene encoding vitamin D–binding protein are associated with circulating vitamin D metabolite levels in healthy infants and toddlers.

Late-onset sepsis (LOS) in very low birth weight (VLBW) infants is associated with significant morbidity and mortality. The ability to predict mortality in infants with LOS based on clinical and laboratory factors at presentation of illness remains limited.

Capillary integrity continues to challenge critical care physicians worldwide when treating children with sepsis. Vascular growth factors, specifically angiopoietin-1 and angiopoietin-2, play opposing roles in capillary stabilization in patients with sepsis. We aim to determine whether pediatric patients with severe sepsisshock have persistently high angiopoietin-21 ratios when compared with nonseptic PICU patients over a 7-day period.
