ABSTRACT
OBJECTIVE: Determine whether urine biomarkers NGAL (neutrophil gelatinase-associated lipocalin), KIM-1 (kidney injury molecule 1) and IL-18 (interleukin-18) are associated with abnormal MRI findings in neonates with hypoxic-ischemic encephalopathy (HIE) who underwent therapeutic hypothermia (TH). STUDY DESIGN: Secondary analysis of a multicenter, prospective study of neonates with HIE requiring TH. Urine biomarkers were obtained at 12 and 24 h of life (HOL). Brain MRI was scored per NICHD criteria. Association between biomarkers and MRI stage was determined. RESULTS: In 57 neonates with HIE, only IL-18 at 24 HOL was significantly increased in neonates with MRI Stage 2B or greater, compared to Stage 2A or less (mean 398.7 vs. 182.9 pg/mL, p = 0.024.) A multivariate model including IL-18 at 24 HOL and 5-min Apgar performed best, with an AUC of 0.84 (SE = 0.07, p = 0.02). CONCLUSIONS: Elevated urine IL-18 at 24 HOL was associated with more severe brain MRI abnormalities among neonates with HIE.

OBJECTIVES: Variability in opioid-prescribing practices after common pediatric surgical procedures at our institution prompted the development of opioid-prescribing guidelines that provided suggested dose limitations for narcotics. The aims of this study were to improve opioid prescription practices through implementation of the developed guidelines and to assess compliance and identify barriers preventing guideline utilization. METHODS: We conducted a single-center cohort study of all children who underwent the most common outpatient general surgery procedures at our institution from August 1, 2018, to February 1, 2020. We created guidelines designed to limit opioid prescription doses based on data obtained from standardized postoperative telephone interviews. Three 6-month periods were evaluated: before guideline implementation, after guideline initiation, and after addressing barriers to guideline compliance. Targeted interventions to increase compliance included modification of electronic medical record defaults and provider educations. Differences in opioid weight-based doses prescribed, filled, and taken, as well as protocol adherence between the 3 timeframes were evaluated. RESULTS: A total of 1033 children underwent an outpatient procedure during the 1.5-year time frame. Phone call response rate was 72.22%. There was a significant sustained decrease in opioid doses prescribed ( P < 0.0001), prescriptions filled ( P = 0.009), and opioid doses taken ( P = 0.001) after implementation, without subsequent increase in reported pain on postoperative phone call ( P = 0.96). Protocol compliance significantly improved (62.39% versus 83.98%, P < 0.0001) after obstacles were addressed. CONCLUSIONS: Implementation of a protocol limiting opioid prescribing after frequently performed pediatric general surgery procedures reduced opioids prescribed and taken postoperatively. Interventions that addressed barriers to application led to increased protocol compliance and sustained decreases in opioids prescribed and taken without a deleterious effect on pain control.

PURPOSE: This study compared the effectiveness of age-appropriate, high technology, interactive virtual reality (VR) distraction with standard care (SC) provided by the nurse on adolescents' acute procedural pain intensity perception during burn wound care treatment in the ambulatory clinic setting. DESIGN: This randomized controlled trial included 43 adolescents ages 10-21 from the ambulatory burn clinic of a large children's hospital. METHODS: Blinded study participants were randomly assigned to either VR or SC (non-significantly different, current mean burn surface area, 1.3 and 1.7, respectively) during the first burn wound care procedure in the burn clinic. Blinded research staff collected pre-procedure data including Spielberger's State-Trait Anxiety Inventory and postprocedure wound care pain intensity using the Adolescent Pediatric Pain Tool. A total of 41 participants completed all study procedures. RESULTS: No statistically significant difference in burn wound care procedural pain was noted between the VR and SC groups after adjusting for several factors. Pre-procedure state and trait anxiety correlated with reported pre-procedure pain. Wound care pain was found to be significantly associated with pre-wound care pain score, time from original burn to clinic burn care treatment, and length of wound care treatment. These factors accounted for approximately 45% of the variation in pain scores during wound care treatment. PRACTICE IMPLICATIONS: VR distraction can be a useful pain management strategy but may not take the place of the unique nurse-patient relationship that occurs during clinical encounters. Tailoring pain management during burn wound care requires consideration of anxiety, time from the burn injury to the wound care procedure, length of time of the wound care procedure, and pretreatment pain level. Knowing patients' needs, desires, and temperaments along with the specifics about the healthcare procedures are critical to formulating individualized care plans that may or may not include VR. Newer technology, such as easier-to-use, less expensive VR, may assist with translation into practice making its clinical use more routine.

The health benefits of soy foods are attributed to the high-quality protein and the bioactive compounds such as isoflavones. We previously reported that feeding obese (fa/fa) Zucker rats soy protein concentrates (SPCs) with low isoflavone (LIF) and high isoflavone (HIF) for 9 weeks significantly reduced liver steatosis compared to a casein control (C) diet. The current study extended the dietary treatments to 18 weeks to investigate the long-term effect of LIF and HIF SPC diets. 6-week-old male lean (L, n = 21) and obese (O, n = 21) Zucker rats were fed a casein C diet, LIF and HIF SPC diets for 18 weeks and body weight (BW) was recorded twice weekly. Rats were killed after 18 weeks to measure liver steatosis and serum aspartate aminotransferase and alanine aminotransferase. Obese rats had significantly greater final BW, liver weight, liver weight as the percentage of BW, and steatosis score compared to lean rats in all three dietary groups. The obese high-isoflavones (OHIF) group had significantly higher BW compared to obese control (OC) group (P < .0001) and obese low-isoflavones (OLIF) group (P = .01). OC group had significantly greater liver weight, liver weight as the percentage of BW, and liver steatosis score compared to OLIF (P = .0077, P < .0001 and P < .0001, respectively) and OHIF (P = .0094, P < .0001, and P < .0001, respectively) groups. Taken together, long-term feeding of SPC diets protected against liver steatosis regardless of isoflavone levels.

BACKGROUND: Caregivers of tracheostomized children must learn and demonstrate multiple tracheostomy care skills. At our hospital, caregiver education is provided through a combination of written instructions, classroom sessions, hands-on practice with a manikin, and bedside demonstration. As part of a quality improvement initiative, caregivers were provided a training doll to practice skills. METHODS: A training doll was provided to caregivers of children within the first week of tracheostomy placement to practice skills. Two questionnaires were utilized during the education process to evaluate utility of the training dolls, skills practiced, and confidence in performing skills. The first questionnaire was completed at the time of the classroom session and the second questionnaire after training was completed. A chart review was conducted to compare outcomes for children whose caregivers did and did not receive a training doll. RESULTS: Caregivers of 33 children with a tracheostomy received training dolls, and 28 were not provided dolls. The majority of caregivers felt the training doll was helpful for practicing skills (initial 93%, second questionnaire 85%). Some caregivers reported a lack of confidence in changing the tracheostomy tube (47%) and using a self-inflating bag (21%) in the initial questionnaire. Confidence increased for all skills in the second questionnaire. Few caregivers reported not using the training doll (initial 21%, second 11%). There were no significant differences in hospital length of stay (LOS) (P = .21) or time to complete training (P = .21) for children whose caregivers were and were not provided a doll. CONCLUSIONS: The majority of caregivers utilized the training doll to practice tracheostomy skills and found it helpful for training. The training doll did not significantly impact hospital LOS or time to complete training. Use of a training doll to practice tracheostomy skills is an additional tool to assist caregivers with learning required skills prior to discharge home.

BACKGROUND: Essential skills for respiratory therapists extend beyond the traditional scope of therapy. Respiratory therapists are expected to communicate effectively, deliver bedside education, and practice within interprofessional teams. Respiratory therapy entry-to-practice program accreditation standards require evaluation of student competence in communication and interprofessional practice. This study aimed to determine if entry into practice programs include curriculum and competency evaluation for oral communication, patient education, telehealth, and interprofessional activities. METHODS: The primary objective was to identify the curriculum and method of competency evaluation. The secondary objective was to compare degree programs. Directors of accredited respiratory therapy programs were invited to complete an anonymous survey with regard to degree program type, oral communication, patient education, learning strategies, telehealth, and interprofessional activities. Degree programs were classified as associate's of science 2 year, associate's of science < 2 year, or bachelor's of science. RESULTS: Of 370 invited programs, respondents in 136 programs (37%) completed the survey. Oral communication competence was evaluated by 82%. Patient education curriculum and competency evaluation were reported by 86% and 73%, respectively. Telehealth was rarely included or evaluated. Interprofessional activities were included by 74%, of whom 67% evaluated competency. Bachelor's of science programs were more likely to include a specific patient education course (P = .004), evaluate oral communication competency with unpaid preceptors (P = .036), and evaluate interprofessional competence through formal interprofessional programs (P = .005). Associate's degree 2-year programs used laboratory proficiency for patient education competency evaluation more often than other programs (P = .01). associate's of science < 2-year programs were more likely to include simulation experiences that involved motivational interviewing (P = .01). CONCLUSIONS: Differences exist among program types for curriculum and competency evaluation. Telehealth was rarely included or evaluated at any degree level. Programs should evaluate the need for enhanced patient education and telehealth instruction.

BACKGROUND: Inhaled corticosteroids (ICSs) are a fundamental pillar of most regimens for long-term control of persistent asthma. Poor adherence to ICS medication is a common problem in the asthma population that can lead to poor asthma control. We hypothesized that conducting a follow-up telephone call after general pediatric clinic visits for asthma would improve refill persistence. METHODS: We conducted a prospective cohort analysis of pediatric and young adult subjects followed in our pediatric primary care clinic for asthma on ICS medication found to have poor ICS refill persistence. This cohort received a follow-up telephone outreach call 5-8 weeks after the clinic visit. The primary outcome measure was refill persistence with regard to ICS therapy. RESULTS: There were 289 subjects who met the inclusion criteria and did not meet any exclusion criteria for the study (n = 131 in the primary cohort, n = 158 in the post-COVID cohort). The mean ICS refill persistence increased significantly for subjects in the primary cohort (39.4 ± 30.8% post intervention vs 32.4 ± 19.7% pre intervention) (P = .02) but not in the post-COVID cohort (36.4 ± 25.6% post intervention vs 38.9 ± 21.0% pre intervention) (P = .26). There was not a statistically significant change in hospitalizations after the intervention in either the primary or the post-COVID cohorts (P = .08 and .07, respectively). Systemic corticosteroid courses and emergency department visits decreased significantly post intervention (P = .01 and P = .004, respectively) in the primary group but not in the post-COVID group (P = .75 and P = .16, respectively). CONCLUSIONS: These results suggest that telephone outreach after out-patient clinic visits for asthma may have short-term benefit in ICS refill persistence; however, the effect size was small.

BACKGROUND: Neonates with hypoxic ischemic encephalopathy (HIE) receiving therapeutic hypothermia are at high risk of acute kidney injury (AKI). METHODS: We performed a two-site prospective observational study from 2018 to 2019 to evaluate the utility of renal near-infrared spectroscopy (NIRS) in detecting AKI in 38 neonates with HIE receiving therapeutic hypothermia. AKI was defined by a delayed rate of serum creatinine decline (< 33% on day 3 of life, < 40% on day 5, and < 46% on day 7). Renal saturation (Rsat) and systemic oxygen saturation (SpO2) were continuously measured for the first 96 h of life (HOL). Renal fractional tissue oxygen extraction (RFTOE) was calculated as (SpO2 - Rsat)/(SpO2). Using renal NIRS, urine biomarkers, and perinatal factors, logistic regression was performed to develop a model that predicted AKI. RESULTS: AKI occurred in 20 of 38 neonates (53%). During the first 96 HOL, Rsat was higher, and RFTOE was lower in the AKI group vs. the no AKI group (P < 0.001). Rsat > 70% had a fair predictive performance for AKI at 48-84 HOL (AUC 0.71-0.79). RFTOE ≤ 25 had a good predictive performance for AKI at 42-66 HOL (AUC 0.8-0.83). The final statistical model with the best fit to predict AKI (AUC = 0.88) included RFTOE at 48 HOL (P = 0.012) and pH of the infants' first postnatal blood gas (P = 0.025). CONCLUSIONS: Lower RFTOE on renal NIRS and pH on infant first blood gas may be early predictors for AKI in neonates with HIE receiving therapeutic hypothermia. A higher resolution version of the Graphical abstract is available as Supplementary information.

Soy's anti-inflammatory properties contribute to the health benefits of soy foods. This study was designed to investigate the bioavailability of soy isoflavones and whether the isoflavone content of soy protein concentrate diet would affect serum inflammatory proteins in an obese (fa/fa) Zucker rat model. Six-week-old male lean (L) and obese (O) Zucker rats were fed a casein control diet (C), soy protein concentrate with low isoflavones (SPC-LIF), or soy protein concentrate with high isoflavones (SPC-HIF) (7 rats/dietary group) before being killed at 9 and 18 weeks. Serum samples were analyzed for isoflavones and inflammatory proteins. At both time points, serum total (aglycone + conjugates) genistein, daidzein, and equol concentrations were significantly higher in L-SPC-HIF and O-SPC-HIF groups compared with L-SPC-LIF and O-SPC-LIF groups, respectively, and were not detectable in either L-C or O-C groups. At week 9, serum C-reactive protein (CRP) concentration was significantly lower in O-SPC-HIF group compared with O-C and O-SPC-LIF group, whereas proteins tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels did not differ between any groups. At week 18, serum CRP levels in both O-SPC-HIF and O-SPC-LIF groups were significantly lower compared with the O-C group. TNF-α level was higher in the O-SPC-LIF group compared with both O-C and O-SPC-HIF groups, whereas IL-6 levels were not different between any groups. Taken together, feeding Zucker rats SPC-LIF and SPC-HIF diets led to different serum isoflavone concentrations in both L and O Zucker rats and altered CRP and TNF-α levels in obese Zucker rats compared with controls.

INTRODUCTION: Sepsis prevention pathways, which often include blood and urine cultures, are common in children's hospitals. Fever and tachycardia, signs often seen in patients with appendicitis, frequently trigger these pathways. We hypothesized that cultures were frequently obtained in children with appendicitis. MATERIALS AND METHODS: We conducted a single-center retrospective cohort study evaluating children with image-confirmed appendicitis from 4/1/2019 to 10/1/2020, coinciding with the initiation of sepsis prevention pathways. Factors associated with culture acquisition, as well as culture results, treatment, and outcomes were evaluated. RESULTS: Six hundred and fifty eight children presented with acute appendicitis during the 1.5-year period, with a median age of 10.67 years (interquartile range (IQR) 8.17-14.08). Cultures were obtained in 22.9%, including blood culture (BCx) in 8.1% and urine culture (UCx) in 17.9%. Culture acquisition decreased by 17.6% after sepsis protocol initiation. Blood culture acquisition correlated with fever (P = .003) and younger age (P = .03), whereas the attainment of BCx and UCx was associated with female sex (P = .04, P < .0001), complicated appendicitis (P = .0001, P = .03), and unknown diagnosis (P < .0001, P < .0001). There were five positive UCx (4.24%); however, all remained asymptomatic despite a short antibiotic duration dictated by institutional appendicitis protocol. The one positive BCx (1.89%) was suspected contamination and not treated. DISCUSSION: The findings of this cohort suggest a low incidence of positive culture as well as lack of impact on clinical management in image-proven appendicitis and the initiation of a sepsis bundle without automatic culture acquisition may result in decreased culture attainment.

BACKGROUND: Regular care and cleaning of positive airway pressure (PAP) devices are important for maintaining equipment in the home. Illness and hospitalization have occurred from inadequate cleaning and use of tap water in the humidifier. In recent years, ozone and ultraviolent-light disinfection devices have been advertised for cleaning home PAP equipment. Our clinic provides instructions; however, cleaning practices performed in the home are unknown. METHODS: A survey of home cleaning practices for PAP equipment was conducted in a pediatric sleep clinic during 2019-2020. Survey domains were method, cleaning and replacement frequency for each component, type of water used, instruction preferences, and demographics. The primary aim was to identify home PAP cleaning practices and compare with provided instructions. The secondary aim was to determine if respiratory-related symptoms (eg, congestion, runny nose, sneezing, coughing) occurred or increased with PAP use or inadequate cleaning. RESULTS: The survey was completed by 96 respondents. Most reported weekly cleaning of mask (36, 38%), tubing (41, 43%), and humidifier (31, 33%) with soap and water as the primary method for each. The majority used distilled water in the humidifier (74, 77%) and reported respiratory symptoms did not occur with PAP use (64, 67%). Very few indicated a device was used to clean equipment. No associations were found between length of time for PAP use and cleaning practices. There was a moderately low correlation between age and cleaning. Increased age was associated with decreased cleaning frequency (r = 0.20, P = .048). CONCLUSIONS: Care and cleaning practices of home PAP equipment varied from instructions provided in clinic. Most reported at least weekly cleaning of items for which daily cleaning is recommended. Few reported using a device for cleaning or having respiratory symptoms from PAP treatment.

Pupil size and reactivity have been studied to objectively measure pain utilizing pupillometry measurements. Given the challenges associated with treating vaso-occlusive pain in pediatric patients with sickle cell disease, better assessment tools are needed. The objective of this study is to establish normative values for pupil size and reactivity in pediatric patients with sickle cell disease with the hope that pupillometry can be used as a tool to objectively measure pain and response to treatment with analgesic medications. Readings were performed using a NeurOptics PLR-2000 pupillometer. Forty-four males and 38 females, all black, were studied. Their median age was 11 years (range: 2 to 21). When comparing our participants with white participants in a previously published pediatric study, there was a significant difference in maximum constriction velocity ( t =3.45, P =0.009), maximum pupil size ( t =-5.57 mm, P <0.0001), and minimum pupil size ( t =-3.24, P =0.002). There was no significant difference in pupil size and reactivity between patients with sickle cell disease and black patients without the disease when compared with the previously published study. Therefore, further investigation of pupillometry within the black population during vaso-occlusive crisis and in the "well state" is warranted in pediatric patients with sickle cell disease.

Non-alcoholic fatty liver disease (NAFLD), is one of the main liver diseases in the US and the world which often is related to obesity. Previously, we reported short- and long-term consumption of soy protein isolate diet with high isoflavones can reduce liver steatosis in the male and female obese Zucker rat model. However, the effects of high vs. low soy isoflavones on NAFLD is less known. The objectives of the present study were to examine the role of isoflavones levels in soy protein concentrate diets on protection against NAFLD in an obese rat model. Forty-two 6-week old lean (L, n = 21) and obese (O, n = 21) Zucker rats were randomly assigned to 1 of 3 dietary groups: casein diet (C = control), soy protein concentrate with low isoflavones (LIF), or soy protein concentrate with high isoflavones (HIF) for 9 weeks. Rats were weighed twice weekly. After 9 weeks, rats were sacrificed and samples of livers were taken for histopathological analysis. Serums were collected to measure ALT and AST levels. Results indicate that obese rats gained significantly more weight than lean rats for all three diet groups (P < 0.001). No significant difference in body weight between LC, LLIF and LHIF was noted. However, the OLIF and OHIF rats gained significantly more weight than OC rats (P < 0.001). Liver steatosis scores were significantly greater in obese rats compared to lean rats (P < 0.001). The OLIF and OHIF-fed rats had significantly reduced steatosis scores than OC rats (P = 0.013 and P < 0.001, respectively). The serum ALT levels were significantly greater in OC, OLIF and OHIF compared to LC, LLIF and LHIF, respectively (P < 0.001, P < 0.001, and P = 0.011). AST serum levels were greater in OC and OLIF compared to LC and LLIF, respectively (P = 0.001 and P = 0.022). In summary, we found that soy protein concentrate with isoflavones protects against liver steatosis and the protection is greater with a higher concentration of isoflavones.
ABSTRACT
Objective: The goal of this study was to determine the prevalence of SARS-CoV-2 infections in pediatric front-line health care workers (HCWs) using SARS-CoV-2 serum antibodies as an indicator of infection. Methods: In this cross-sectional study, we collected blood samples and survey responses from HCWs in a 38-bed pediatric emergency department. Serum antibodies to SARS-CoV-2 (IgM and/or IgG) were measured using a 2-step enzyme-linked immunosorbent assay (ELISA) to detect antibodies against the Spike protein receptor binding domain (RBD), the ectodomain of Spike (S), and the nucleoprotein (N). Results: We collected survey responses and serum samples from 54 pediatric front-line HCWs from October 2020 through April 2021. Among the 29 unvaccinated HCWs, 4 (13.7%) had antibodies to SARS-CoV-2. For the 25 vaccinated HCWs, 10 (40%) were seropositive; 3 were <10 days from the first vaccine dose and 7 were ≥10 days after the first dose. Two of the 10 seropositive vaccines had a prior positive reverse transcription polymerase chain reaction test. Individuals ≥10 days from receiving the first vaccine dose were 37.5 (95% CI: 3.5-399.3) times more likely to have SARS-CoV-2 antibodies than unvaccinated individuals or those <10 days from first vaccine dose. Conclusions: Evidence of widespread SARS-CoV-2 infections was not found in unvaccinated front-line HCWs from a pediatric ED as of April 2021. Future work will be required to determine the reasons underlying the lower SARS-CoV-2 antibody prevalence compared to adult HCWs.
ABSTRACT
OBJECTIVE: To assess the association between hypertrophic cardiomyopathy (HCM) and mortality among infants of diabetic mothers (IDMs). METHODS: We performed a retrospective cohort study of hospitalized IDMs admitted at ≤14-days-old in the Pediatric Health Information System (years 2004 - 2019). Multivariable logistic regression was used to evaluate the association between HCM and mortality; covariates in the model were prematurity, sex, and congenital malformations of the cardiovascular, nervous, urinary and musculoskeletal systems. RESULTS: Among 32,993 IDMs, there were 203 (0.6%) with HCM. Black and Hispanic children were disproportionately represented among children with HCM compared to those without HCM (23.2 vs. 14.9%, p = .001 for Black, and 30.0 vs. 22.1%, p = .007 for Hispanic). IDMs with HCM were also larger at birth (median birth weight 4120 g [interquartile range 3600-4703] vs. 3270 g [interquartile range 2535-3910]; p < .001). In-hospital mortality in patients with HCM was greater than in those without HCM (4.9 vs. 1.3%, p < 0.001), and odds of mortality were greater among those with HCM (adjusted odds ratio 2.10, 95% confidence interval: 1.04-4.25; p = .038). CONCLUSION: We identify HCM as a contributor to in-hospital mortality. These data reinforce the need for more specific diagnostic criteria, better prevention of maternal diabetes, and effective therapies for HCM in IDMs.

BACKGROUND: Obstructive sleep apnea (OSA) is diagnosed through polysomnography (PSG) testing and commonly treated with positive airway pressure (PAP). The initial recommended treatment for pediatric OSA is adenotonsillectomy, but when this is contraindicated or ineffective, PAP is the next option. Children followed in our pediatric sleep disorders center who are diagnosed with OSA and meet criteria for therapy are empirically prescribed a PAP device, usually auto-titrating PAP (APAP), to avoid delays in therapy. Titration PSG is performed later to assess adequacy of settings. The aims of this study were to determine how often PSG titration results in changes to empirically prescribed PAP and to assess adherence to therapy before and after PSG titration. METHODS: A retrospective medical records review was completed for children diagnosed with OSA, prescribed PAP, and had a titration PSG within a 5-y consecutive period of 2008-2012. Demographic data, type of device, pressure settings, and adherence downloads were reviewed. Adherence was assessed before and after titration overall and compared for those who did and did not have therapy changes following titration. RESULTS: The study included 121 participants. Median age at the time of the diagnostic PSG was 11 (interquartile range [IQR] 8-14) y. Most (106, 88%) were initially prescribed APAP. Median length of time between initial and follow-up PSG was 6.4 (IQR 4.4-10.1) months. The majority (94, 78%) had therapy changes following titration. Overall, adherence percentage > 4 h per night was not significantly increased post titration (P = .47). There were no statistically significant differences in adherence between those who had therapy changes and those who did not (P = .26). CONCLUSIONS: Titration studies resulted in therapy modifications for most children. Adherence was not increased following the titration PSG. Changes in therapy did not result in increased adherence. Titration PSGs may optimize empirically prescribed settings.

The purpose of this study was to determine the effect of exercise during pregnancy in sedentary women with obesity on longitudinal changes in long-chain acylcarnitine (LC-AC) concentrations. We hypothesized that exercise training would significantly decrease circulating LC-ACs throughout gestation compared with a nonexercise control group. Pregnant women with obesity considered otherwise healthy [n = 80, means ± SD; body mass index (BMI): 36.9 ± 5.7 kg/m2] were randomized into an exercise (n = 40, aerobic/resistance 3 times/wk, â¼13th gestation week until birth) or a nonexercise control (n = 40) group. At gestation week 12.2 ± 0.5 and 36.0 ± 0.4, a submaximal exercise test was conducted, and indirect calorimetry was used to measure relative resting energy expenditure (REE), as well as respiratory exchange ratio (RER) at rest. Fasting blood samples were collected and analyzed for LC-AC concentrations. Fitness improved with prenatal exercise training; however, exercise training did not affect circulating LC-AC. When groups were collapsed, LC-ACs decreased during gestation (combined groups, P < 0.001), whereas REE (kcal/kg/day, P = 0.008) increased. However, average REE relative to fat-free mass (FFM) (kcal/kg FFM/day) and RER did not change. There was an inverse relationship between the change in RER and all LC-ACs (except C18:2) throughout gestation (C14: r = -0.26, P = 0.04; C16: r = -0.27, P = 0.03; C18:1: r = -0.28, P = 0.02). In summary, a moderate-intensity exercise intervention during pregnancy in women with obesity did not alter LC-ACs concentrations versus control, indicating that the balance between long-chain fatty acid availability and oxidation neither improved nor worsened with an exercise intervention.NEW & NOTEWORTHY This research showed that a moderate-intensity prenatal exercise program, consisting of aerobic and resistance training, did not negatively impact normal alterations in substrate supply and demand for the mother and the offspring throughout gestation. Findings provide support for metabolic safety of exercise during pregnancy.

OBJECTIVE: To evaluate the predictive performance of urine biomarkers for acute kidney injury (AKI) in neonates with hypoxic ischemic encephalopathy (HIE) receiving therapeutic hypothermia. STUDY DESIGN: We performed a multicenter prospective observational study of 64 neonates. Urine specimens were obtained at 12, 24, 48, and 72 hours of life and evaluated for neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), cystatin C, interleukin-18 (IL-18), tissue inhibitor of metalloproteinases 2 (TIMP2), and insulin-like growth factor-binding protein 7 (IGFBP7). Logistic regression models with receiver operating characteristics for area under the curve (AUC) were used to assess associations with neonatal modified KDIGO (Kidney Disease: Improving Global Outcomes) AKI criteria. RESULTS: AKI occurred in 16 of 64 infants (25%). Neonates with AKI had more days of vasopressor drug use compared with those without AKI (median [IQR], 2 [0-5] days vs 0 [0-2] days; P = .026). Mortality was greater in neonates with AKI (25% vs 2%; P = .012). Although NGAL, KIM-1, and IL-18 were significantly associated with AKI, the AUCs yielded only a fair prediction. KIM-1 had the best predictive performance across time points, with an AUC (SE) of 0.79 (0.11) at 48 hours of life. NGAL and IL-18 had AUCs (SE) of 0.78 (0.09) and 0.73 (0.10), respectively, at 48 hours of life. CONCLUSIONS: Urine NGAL, KIM-1, and IL-18 levels were elevated in neonates with HIE receiving therapeutic hypothermia who developed AKI. However, wide variability and unclear cutoff levels make their clinical utility unclear.

PURPOSE: To explore and compare the perceptions of nurses and parent/family advisors regarding pediatric nurses' moral obligations to children and families during an active shooter event in a children's hospital. DESIGN AND METHODS: This was a descriptive, exploratory study using survey methodology. A convenience sample of all licensed nurses and parent/family advisors from four children's hospitals across the United States were recruited. Surveys consisted of five primary domains including Appropriateness of National Guidelines, Personal Preparedness, Moral Accountability, Professional/Legal Concerns, and Personal Risk Expectations. Frequency counts and percentages were calculated for each survey item. RESULTS: Data from 874 pediatric nurses and 81 parent/family advisors were analyzed. Most respondents believed the Run-Hide-Fight campaign should be changed to Secure-Preserve-Fight. Only 30% of nurses felt mentally prepared to respond to an active shooter event. Most respondents agreed that nurses have a professional duty to protect their patients, but agreed that it was a personal choice, not a moral obligation, to accept potentially fatal risks. Hospital setting and patient vulnerability often influenced nurses' perceived obligations to patients. Most respondents reported they would not leave their patient/child during an active shooter event. CONCLUSIONS: Nurses feel morally obligated to patients, but must balance their own personal risk tolerance level against the need to protect patients and families. PRACTICE IMPLICATIONS: Hospitals need in-depth active shooter training for both nurses and parents as well as safety plans that address both evacuation protocols and measures to secure in place to protect the lives of patients, families, and staff.

OBJECTIVES: To identify medium-term results following cutting balloon angioplasty (CBA) for branch pulmonary artery stenosis (PAS) and predictors of successful intervention. BACKGROUND: CBA has emerged as a successful alternative therapy for PAS resistant to conventional balloon angioplasty techniques but there is little information on medium and long-term outcomes. METHODS: This is a descriptive, single center, retrospective chart review of pediatric patients who underwent CBA for PAS at Arkansas Children's Hospital between May 2005 and December 2020. We reviewed demographics, procedural specifics, and 30-day complications. RESULTS: Forty-four patients underwent pulmonary artery CBA on 114 pulmonary artery segments through 126 catheterization cases, totaling 148 CBA events. Thirty-three individual pulmonary arteries underwent repeat intervention. Average minimal luminal diameter increase from pre-CBA to end of follow-up was 57% (CI, 38%-75%). Absence of Tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries (TOF/PA/MAPCAs) and the absence of Alagille Syndrome, Williams Syndrome, or Arterial Tortuosity Syndrome (ATS) were associated with increased odds of sustained success by 70% (CI, 0.11-0.79) and 91% (CI, 0.02-0.56), respectively. Increasing the cutting balloon diameter-to-minimal luminal diameter ratio by 0.5 increased odds of successful intervention by 2.37-fold (CI, 1.7-3.3). Seven patients had 30-day complications including one death. CONCLUSIONS: In the longest follow-up to date of children and adolescents who underwent CBA for branch PAS, we found that there was moderate medium-term success. Additionally, absence of TOF/PA/MAPCAs, absence of Alagille Syndrome, Williams Syndrome, or ATS, and high cutting balloon diameter-to-minimal luminal diameter ratio are predictors of sustained results.
