RESUMEN

AIMS: To compare the stress level in parents of children with new-onset type 1 diabetes receiving a fixed insulin dose for a fixed range of carbohydrates (CHOs) to parents of children receiving a precise insulin dose for a precise number of CHOs using an insulin-to-carbohydrate ratio (ICR). METHODS: Twenty-four participants (8-14 years) were randomized to receive a fixed dose of insulin for a fixed range of CHOs (FD group) or a precise dose of insulin for a precise number of carbohydrates using an ICR (ICR group). The primary endpoint was parental stress measured with the parental stress survey (PSS) 1 to 4 months after diagnosis. Secondary endpoints included glycemic variability, glycated haemoglobin (HbA1C ) and safety. RESULTS: Compared to parents of children in the ICR group, those from the FD group reported less stress during the first 4 months after diagnosis (p = 0.022). Glycemic variability and HbA1C were similar in both groups. None of the patients from either group required an emergency department visit or hospitalization. CONCLUSIONS: In comparison to precise insulin dosing using an ICR, fixed insulin dosing for a fixed range of CHOs may be less stressful for parents to learn and employ when initially taught diabetes management skills for their child with new-onset type 1 diabetes.

RESUMEN

INTRODUCTION: In chronic diseases, disease-related distress can impact disease outcomes. Distress and haemophilia-related distress has been demonstrated in people with haemophilia (PwH). The association of haemophilia-related distress on disease outcomes among PwH is unknown. AIM: To study the association of haemophilia-related distress with haemophilia specific outcomes, including adherence to prophylactic therapy, the presence of a target joint, healthcare utilization and work-impairment. METHODS: In a cross-sectional study, adults with haemophilia A or B were enrolled in a study to validate the haemophilia-related distress questionnaire (HRDq). In this planned analysis, univariate and multivariate associations between the HRDq total score and disease outcomes were explored. RESULTS: The 114 participants in this analysis were male, mostly with haemophilia A (92%) and severe disease (52%) with a median age of 31.9 years. On univariate analysis, HRDq total score (5-point change) was associated with the presence of a target joint (P = .002), high healthcare utilization (P = .011), poor adherence (P = .033) and work-impairment (P ≤ .001). After adjustment for age, race, severity and other potential confounders, adherence (aß 0.33, 95% CI .17, .49) and work-impairment (aß 4.69, 95% CI 3.27-6.1) remained statistically significantly associated with HRDq total score. CONCLUSION: Haemophilia-related distress is associated with poor adherence to factor prophylaxis and work-impairment. The direction of the association (causation) is yet to be determined and requires future study.

RESUMEN

Children with cardiac disease are at significantly higher risk for in-hospital cardiac arrest (CA) compared with those admitted without cardiac disease. CA occurs in 2-6% of patients admitted to a pediatric intensive care unit (ICU) and 4-6% of children admitted to the pediatric cardiac-ICU. Treatment of in-hospital CA with cardiopulmonary resuscitation (CPR) results in return of spontaneous circulation in 43-64% of patients and survival rate that varies from 20 to 51%. We aimed to investigate the change in functional status of survivors who experienced an in-hospital CA using the functional status scale (FSS) in our heart center by conducting a retrospective study of all patients 0-18 years who experienced CA between June 2015 and December 2020 in a free-standing university-affiliated quaternary children's hospital. Of the 165 CA patients, 61% (n = 100) survived to hospital discharge. The non-survivors had longer length from admission to CA, higher serum lactate levels peri-CA, and received higher number of epinephrine doses. Using FSS, of the survivors, 26% developed new morbidity, and 9% developed unfavorable outcomes. There was an association of unfavorable outcomes with longer CICU-LOS and number of epinephrine doses given. Sixty-one-percent of CA patients survived to hospital discharge. Of the survivors, 26% developed new morbidity and 91% had favorable outcomes. Future multicenter studies are needed to help better identify modifiable risk factors for development of poor outcomes and help improve outcomes of this fragile patient population.

RESUMEN

OBJECTIVES: Children in the emergency department (ED) often require sedation for head computed tomography (CT) to ensure adequate image quality. Image acquisition time for a head CT using a conventional single-source CT scanner is approximately 12 seconds; however, after installation in November 2017 of 2 new dual-source dual-energy CT scanners, that time decreased to 1 to 3 seconds. We hypothesized that fewer patients would require sedation using the faster CT scanners. METHODS: We conducted a retrospective chart review of patients aged 0 to 18 years undergoing head CT at 2 pediatric EDs within 1 hospital system, 2 years before and 2 years after installation of the faster CT scanner. Patients undergoing multiple CTs or other procedures were excluded. Demographic information, diagnosis, disposition, sedatives (chloral hydrate, dexmedetomidine, etomidate, fentanyl, ketamine, midazolam, methohexital, pentobarbital, and propofol) administered before imaging, and ED length of stay were analyzed. RESULTS: A total of 15,175 patient encounters met inclusion criteria, 7412 before and 7763 after installation of the new CT. The median age was 7 years and 44% were female. Before the new CT scanner was installed 8% required sedation, compared with 7% after (effect size, 0.0341). Midazolam was the most commonly administered sedative. Fewer patients required deep sedation using the faster CT scanner. CONCLUSIONS: After installation of a dual-source dual-energy CT scanner, fewer patients required sedation to complete head CT in the pediatric ED. Faster image acquisition time decreased the need for deep sedation.

RESUMEN

Altered mitochondrial function occurs in sickle cell disease (SCD), due in part to low nitric oxide (NO) bioavailability. Arginine, the substrate for NO production, becomes acutely deficient in SCD patients with vaso-occlusive pain episodes (VOE). To determine if arginine improves mitochondrial function, 12 children with SCD-VOE (13.6 ± 3 years; 67% male; 75% hemoglobin-SS) were randomized to 1 of 3 arginine doses: (1) 100 mg/kg IV 3 times/day (TID); (2) loading dose (200 mg/kg) then 100 mg/kg TID; or (3) loading dose (200 mg/kg) followed by continuous infusion (300 mg/kg per day) until discharge. Platelet-rich plasma mitochondrial activity, protein expression, and protein-carbonyls were measured from emergency department (ED) presentation vs discharge. All VOE subjects at ED presentation had significantly decreased complex-V activity compared to a steady-state cohort. Notably, complex-V activity was increased at discharge in subjects from all 3 arginine-dosing schemes; greatest increase occurred with a loading dose (P < .001). Although complex-IV and citrate synthase activities were similar in VOE platelets vs steady state, enzyme activities were significantly increased in VOE subjects after arginine-loading dose treatment. Arginine also decreased protein-carbonyl levels across all treatment doses (P < .01), suggesting a decrease in oxidative stress. Arginine therapy increases mitochondrial activity and reduces oxidative stress in children with SCD/VOE. This trial was registered at www.clinicaltrials.gov as #NCT02536170.

RESUMEN

PURPOSE: Institutions are adopting the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) guidelines for pediatric esophageal button battery ingestion (EBBI). Our objective was to evaluate the guidelines' impact on in-hospital resource utilization and short-term clinical outcomes in hemodynamically stable patients after endoscopic battery removal. METHODS: A single-center retrospective review of all EBBI admissions from 2010 to 2020. Patients were divided into two groups based on adoption of national guidelines: pre-guideline (2010-2015) and post-guideline (2016-2020). RESULTS: Sixty-five patients were studied (pre-guideline n = 23; post-guideline n = 42). Compared with pre-guideline, post-guideline use of magnetic resonance imaging (MRI) increased (2/23 [8.7%]; 30/42 [71.4%]; p < 0.001). Post-guideline increases resulted for median days (IQR) receiving antibiotics (0 [0, 4]; 6 [3, 8]; p = 0.01), total pediatric intensive care unit admission (0 [0, 1]; 3 [0, 6]; p < 0.001), and total hospital length of stay (5 [2, 11]; 11.5 [4, 17]; p = 0.02). Two patients in the post-guideline group had delayed presentations despite normal imaging: one with TEF and one with aorto-esophageal fistula. All survived to discharge. CONCLUSION: In EBBI cases managed using the consensus based NASPHAGN guidelines, we report increased resource utilization without improved patient outcomes. Further research should evaluate post-guideline costs and resource utilization.

RESUMEN

OBJECTIVES: The aims of the study were (1) to compare targeted and routine HIV screening in a pediatric emergency department (PED) and (2) to compare provider documented HIV risk assessment with adolescent perception of HIV risk assessment conducted during the PED visit. METHODS: This prospective study ran concurrent to a PED routine HIV screening pilot. Adolescents could be tested for HIV by the PED provider per usual care (targeted testing); if not tested, they were approached for the routine screening pilot. A subset of adolescents completed a questionnaire on HIV risk. χ 2 analysis compared adolescents with targeted testing and routine screening. HIV-tested patients were asked if HIV risk was assessed; κ analysis compared this with documentation in the provider note. RESULTS: Over 4 months, 107 adolescents received targeted testing and 344 received routine screening. One 14-year-old patient tested positive by routine screening; this adolescent had 2 PED visits without targeted testing within 60 days. Compared with routine screening, adolescents with targeted testing were more likely female (82% vs 57%, P < 0.001), 16 years or older (71% vs 44%, P < 0.001), or had genitourinary/gynecologic concerns (48% vs 6%, P < 0.001). Adolescents with HIV risk factors were missed by targeted testing but received routine screening. Adolescents with documented HIV risk assessment were more likely to receive targeted testing. There was moderate agreement (κ = 0.61) between provider documentation and adolescent perception of HIV risk assessment. CONCLUSIONS: There are gaps in PED HIV risk assessment and testing, which may miss opportunities to diagnose adolescent HIV. Routine HIV screening addresses these gaps and expands adolescent HIV testing in the PED.

RESUMEN

Among symptomatic outpatients, subgenomic RNA of severe acute respiratory syndrome coronavirus 2 in nasal midturbinate swab specimens was concordant with antigen detection but remained detectable in 13 (82.1%) of 16 nasopharyngeal swab specimens from antigen-negative persons. Subgenomic RNA in midturbinate swab specimens might be useful for routine diagnostics to identify active virus replication.

RESUMEN

INTRODUCTION: The Patient-Reported Outcomes Measurement Information System (PROMIS) provides measures of health status that assess physical, mental and social well-being from the patient perspective. PROMIS measures are used in clinical practice and research across various patient populations but are not yet validated among patients with haemophilia. AIM: Evaluate the sensitivity of PROMIS to indicators of haemophilia clinical severity and compare PROMIS measures to those from other PRO instruments. METHODS: Male adults with haemophilia (n = 115) completed the PROMIS-29 short form which includes 4 questions for each of 7 domains: depression, anxiety, ability to participate in social roles and activities, physical function, pain interference, fatigue and sleep disturbance. Participant responses for each domain were scored on a T-score metric with a mean of 50 and a standard deviation of 10 based on the original PROMIS reference sample of US adults. Participants also completed other generic and haemophilia-specific health-related quality of life questionnaires. RESULTS: Participants who experienced higher pain and depression levels reported significantly worse health in every PROMIS domain compared with their peers. Those who had recently needed to use crutches, visit an emergency department or were currently unemployed or disabled also reported poor PROMIS scores on most domains. Construct validity was supported by correlations between PROMIS domain scores and domain scores reported using the EQ-5D-5L and Haem-A-QoL. CONCLUSION: The PROMIS instrument provides a potentially valuable tool to evaluate the impact of haemophilia and suggests usefulness in research and clinical practice.

RESUMEN

INTRODUCTION: In patients with haemophilia, general psychological distress as measured by the National Comprehensive Cancer Network (NCCN) distress thermometer has been associated with pain, disability and increased healthcare utilization. AIMS: To develop and validate a measure of haemophilia-related distress. METHODS: After qualitative interviews, the Hemophilia-Related Distress Questionnaire (HRDq) was developed. To validate the HRDq, adults (≥18 years) with haemophilia were enrolled, reported demographic and clinical information, and completed the HRDq and other questionnaires that measured similar constructs. Analysis included factor analysis and assessment of internal consistency using Cronbach's α, convergent validity using Pearson's correlation coefficient, and discriminant validity by comparing subgroups of patients. Test-retest reliability was assessed using an intraclass correlation coefficient (ICC). RESULTS: Among 130 enrolled participants, 126 (median age=32.7 years) completed the 24 item HRDq in a median time of 5.4 minutes with overall HRDq scores ranging from 2 to 83 (median score=31.5; higher scores indicating higher distress). Assessment of convergent validity demonstrated a strong correlation (ρ>.60) of the HRDq total score with the NCCN Distress Thermometer, Haem-A-QoL total Score, and PROMIS-29 Profile social role domain and a mild to moderate correlation with all other questionnaire domains (.3-.59, p < .05). Distress was higher among those who had less education, were not employed, and were disabled and was not significantly different among those with severe compared with non-severe disease. Assessment of test-retest reliability demonstrated an ICC value of .84 (95% CI .71-.91) for the total score. CONCLUSIONS: The HRDq demonstrates good internal consistency, construct and discriminant validity, and retest reliability with a low responder burden.

RESUMEN

Low arginine bioavailability is associated with vaso-occlusive painful crisis (VOC) severity in sickle cell anemia (SCA) and predicts need for pediatric hospitalization. Intravenous arginine therapy has opioid-sparing effects and was found to significantly decrease pain scores in children hospitalized with SCA-VOC in a phase-two randomized placebo-controlled trial (RCT). Efficacy of oral arginine is unknown. Our objective was to determine the safety and efficacy of oral arginine therapy in Nigerian children with SCA. A double-blind RCT of oral L-arginine-hydrochloride (100 mg/kg TID) was conducted in children with SCA-VOC, aged 5-17 years, hospitalized at two Nigerian sites. The primary outcome measure was analgesic usage, quantified by difference in the mean Analgesic Medication Quantification Scale (MQS). Secondary outcomes included daily pain scores, time-to-crisis-resolution and length-of-hospital-stay. An intention-to-treat analysis was performed. Sixty-eight children (age 5-17 years, mean 10.6 ± 0.4 years; 56% male), were randomized to receive L-arginine (35 patients) or placebo (33 patients). The mean total MQS for the arginine group was 73.4 (95% CI, 62.4-84.3) vs 120.0 (96.7-143.3) for placebo (P < .001). The mean rate of decline in worst pain scores was faster in the arginine arm vs placebo (1.50 [1.23-1.77] vs 1.09 [0.94-1.24] point/d, P = .009). Children receiving arginine had a shorter time-to-crisis-resolution (P = .02), shorter hospital-stay (P = .002) and experienced no serious adverse event. Pain control was more rapid, total analgesic requirement was significantly reduced, and most notably, time-to-crisis-resolution and length-of-hospital-stay were shorter in children with SCA-VOC receiving arginine vs placebo. Given the established safety and low cost, oral arginine is a promising adjuvant therapy for SCA-VOC management.

RESUMEN

OBJECTIVE: Infants requiring intestinal resection because of necrotizing enterocolitis (NEC) or small bowel atresia (SBA) may benefit from mucous fistula refeeding (MFR) of enterostomy output to improve nutrition and bowel adaptation before reanastomosis. Previous series demonstrated improved outcomes with MFR but did not account for varied patient characteristics as potential sources of bias. We performed a cohort analysis using multivariable adjusted models to compare outcomes of patients with and without MFR. METHODS: Retrospective chart review was performed for patients with NEC or SBA and small bowel resection with enterostomy and MF. Demographic and outcome data was compared between MFR and non-MFR groups using adjusted multivariable analysis for potential confounding variables. RESULTS: MFR was performed in 65 of 101 patients (64%), including 45 of 75 patients with NEC and 20 of 26 patients with SBA. Reasons for not receiving MFR included bowel stricture, technical limitation, or not otherwise specified. NEC patients receiving MFR had 14 fewer days to achieve full enteral feeds after intestinal reconnection, 22 fewer days of parenteral nutrition, lower peak direct bilirubin by 2.4 mg/dL, and 77% less odds of ursodiol use (all P < 0.01). SBA patients had similar trends not reaching statistical significance. Growth parameters were improved in MFR groups. There were no complications or increased infections from MFR. CONCLUSIONS: This study suggests that MFR safely improves nutritional outcomes in infants with intestinal resection, related to decreased total parenteral nutrition (TPN) dependence and earlier enteral autonomy.

RESUMEN

OBJECTIVES: Children in the emergency department who require computerized tomography (CT) of the head often are given sedative medications to facilitate completion of the study with adequate imaging. A prior study found the two most common medications used to obtain head CT in children were pentobarbital and chloral hydrate; however, these medications have become less popular. We hypothesized that there was variability in medication choice amongst providers in the emergency department and there has been a change in the preferred sedatives used in the last decade. METHODS: We conducted a retrospective multicenter cross-sectional study of children 0-18 years old who received a medication with sedative properties and underwent head CT while in the emergency department from 2007 to 2018, using the Pediatric Health Information System (PHIS) database. The primary outcome measure was the frequency of administration of drugs within an individual sedative class. RESULTS: We analyzed 24,418 patient encounters, of whom 53% received an opioid and 41% received a benzodiazepine. There were statistically significant decreases in the use of barbiturates, chloral hydrate, anti-emetic sedatives, and opioids, while increases in barbiturate combination drugs, benzodiazepines and dexmedetomidine were observed over the study period. The majority of medications were administered parenterally. CONCLUSION: There is wide variability in sedatives used in children to obtain head CT and the preferred drugs have shifted over the last decade.

RESUMEN

BACKGROUND: In the management of pediatric osteomyelitis or septic arthritis, delay in treatment may affect outcome, while receipt of antibiotics prior to culture may affect culture results. We aimed to determine if pathogen identification decreased in cultures that were pretreated with antibiotics. METHODS: We conducted a retrospective cohort study of 584 hospitalized children between 30 days and 18 years of age admitted to two tertiary children's hospitals. Logistic regression assessed the effect of antibiotic duration on blood, bone, joint aspirate, and "other" culture positivity. RESULTS: Overall, 42% of blood cultures, 70% of bone cultures, 39% of joint cultures, and 70% of "other" cultures were positive. Compared with children who did not receive antibiotics prior to culture, there were no significant differences in odds of a positive culture in children whose cultures were pretreated with antibiotics for any of the culture types [OR (95% CI) 0.90 (0.56-1.44) for blood cultures, 0.77 (0.25-2.34) for bone cultures, 0.71 (0.39-1.28) for joint cultures, 1.18 (0.58-2.41) "for other" cultures; all p > 0.05]. Furthermore, the duration (hours) of antibiotics in the pretreated cultures was also not a significant predictor of culture positivity (OR ranged from 0.99-1.00 for all cultures, p > 0.05). CONCLUSIONS: Culture positivity was not associated with antibiotic pretreatment in any of the samples, even for longer duration of antibiotics prior to culture, though the small sample size of subgroups is an important limitation. In pediatric patients hospitalized with osteomyelitis and/or septic arthritis, early initiation of antibiotics may not affect culture positivity.

RESUMEN

OBJECTIVE: To examine levels of plasma osteopontin (OPN), a recently described neuroinflammatory biomarker, in children with abusive head trauma (AHT) compared with children with other types of traumatic brain injury (TBI). STUDY DESIGN: The study cohort comprised children aged <4 years diagnosed with TBI and seen in the intensive care unit in a tertiary children's hospital. Patients were classified as having confirmed or suspected AHT or TBI by other mechanisms (eg, motor vehicle accidents), as identified by a Child Protection Team clinician. Serial blood samples were collected at admission and at 24, 48, and 72 hours after admission. Levels of OPN were compared across groups. RESULTS: Of 77 patients identified, 24 had confirmed AHT, 12 had suspected AHT, and 41 had TBI. There were no differences in the Glasgow Coma Scale score between the patients with confirmed AHT and those with suspected AHT and those with TBI (median score, 4.5 vs 4 and 7; P = .39). At admission to the emergency department, OPN levels were significantly higher in children with confirmed AHT compared with the other 2 groups (mean confirmed AHT, 471.5 ng/mL; median suspected AHT, 322.3 ng/mL; mean TBI, 278.0 ng/mL; P = .03). Furthermore, the adjusted mean trajectory levels of OPN were significantly higher in the confirmed AHT group compared with the other 2 groups across all subsequent time points (P = <.01). CONCLUSIONS: OPN is significantly elevated in children with confirmed AHT compared with those with suspected AHT and those with other types of TBI. OPN expression may help identify children with suspected AHT to aid resource stratification and triage of appropriate interventions for children who are potential victims of abuse.

RESUMEN

INTRODUCTION: Right ventricular pacing is associated with pacemaker induced cardiomyopathy and lesser degrees of pacing-induced LV dysfunction (PIVD) manifested by a reduction in left ventricular ejection fraction (LVEF). Our objective was to determine whether apical 4 chamber strain (A4C) by echocardiography can identify patients at risk of PIVD before LVEF declines. METHODS AND RESULTS: A retrospective chart review of patients (0-21 years) who had a pacemaker with a ventricular lead placed between 2011 and 2017 was performed. Patients were divided into group A (LVEF <55% and/or >10% decline in LVEF within 12 months of pacemaker placement) and group B. Data have collected before and 1 and 12 months postpacemaker implantation. There were 30 patients in the group A and 60 in group B. At 1 and 12 months postpacemaker implantation, the LVEF was significantly lower while the A4C and QRS duration on electrocardiogram were significantly higher in the group A. While the LVEF and A4C became markedly abnormal in group A as early as 1 month, the A4C did not seem to demonstrate such marked abnormalities in group B. However, a sub-analysis of patients in the group A with preserved LVEF at 1 month demonstrated significant worsening in their A4C at that time. CONCLUSION: Myocardial deformation imaging may be a clinically useful tool for the prediction of a decline in LV systolic function following pacemaker implantation. Abnormalities in A4C seem to appear before LVEF decline and as soon as 1-month postpacemaker implantation.

RESUMEN

INTRODUCTION: Rest-activity disruption is an important feature of Duchenne muscular dystrophy (DMD). We sought to describe sleep impairment and its relationship to quality of life (QOL) and to evaluate associations between rest-activity, sleep quality, and 6-minute walk test (6MWT) in DMD. METHODS: Sleep impairment and its relationship to QOL was assessed by questionnaire in 54 children (33 ambulatory, 21 nonambulatory) with DMD. Rest-activity characteristics were calculated for 23 of these children (14 ambulatory, nine nonambulatory) by actigraphy. RESULTS: Pathologic sleep was reported in 11 (20%) participants and correlated with lower QOL but not with ambulatory status. In ambulatory participants who completed actigraphy, rest-activity rhythm fragmentation was associated with subjective sleep impairment. Habitual daytime activity level was associated with 6MWT performance. DISCUSSION: Children with DMD experience substantial sleep impairment that is related to QOL. Wrist actigraphy may be a parsimonious tool for monitoring both sleep and motor impairment in ambulatory children with DMD.

RESUMEN

BACKGROUND: The primary aim of our study was to determine provider variation in diagnostic yield in a pediatric endoscopy center. Secondary aims were to examine ileal intubation rates as well as procedural complications at the provider level. METHODS: A retrospective review of sequential pediatric patients who underwent a colonoscopy, completed by June 2018, determined the rates of endoscopically abnormal (EA) and isolated histologically abnormal (IHA) colonoscopies; the overall diagnostic yield was the combination of EA and IHA. RESULTS: In total, 374 charts were reviewed. This study found high variability in diagnostic yield among the 16 clinicians ranging from as low as 22% to as high as 86% (p = 0.11) with an overall diagnostic yield of 48% for colonoscopy; excluding follow-up colonoscopies, the diagnostic yield was 42%. Abnormal calprotectin and abnormal blood tests were associated with higher diagnostic yields of 83 and 65%, respectively, compared with symptoms such as abdominal pain, diarrhea, and rectal bleeding which had yields of 39, 43, and 61%. Ileal intubation rates averaged 90% (range -63-100%, p = 0.06). In patients with a normal colon, there were 21 (6%) patients with an EA ileum and an additional 16 (4%) with an IHA ileum. Prep quality was rated excellent, good, or average in 97%. In addition, there was a low rate of serious complications (1 of 374). CONCLUSIONS: This study highlights the individual variability in diagnostic yield and ileal intubation rates in a pediatric gastroenterology practice. Goals for pediatric endoscopy could include ileal intubation rates of >90% and provider diagnostic yields of >40%.

RESUMEN

STUDY OBJECTIVE: Acute chest syndrome is a leading cause of mortality in patients with sickle cell disease (SCD). Because early detection of acute chest syndrome is directly tied to prognosis, young patients with SCD undergo countless chest radiography screenings throughout their lifetime for commonly occurring acute chest syndrome risk factors such as fever, chest pain, or cough. Chest radiography is not an ideal screening method because it is associated with radiation exposure, which accumulates with repeated imaging. Point-of-care lung ultrasonography is a nonradiating imaging modality that has been used to identify other lung pathology and may have a role in SCD. The goal of this study was to determine the accuracy of point-of-care lung ultrasound to identify an infiltrate suggestive of acute chest syndrome in patients with SCD compared to chest radiography as the gold standard. METHODS: This was a prospective observational study in 2 urban pediatric emergency departments to evaluate the accuracy of point-of-care lung ultrasonography in identifying patients with SCD who were aged 0 to 21 years and had an infiltrate suggestive of acute chest syndrome compared with chest radiography. Clinicians and trainees with point-of-care lung ultrasonographic training obtained informed consent and performed investigational point-of-care lung ultrasonography to evaluate for lung consolidation. A blinded point-of-care lung ultrasonographic expert reviewed results for quality assurance and agreement. Accuracy, sensitivity, specificity, likelihood ratios, and positive and negative predictive value were calculated for point-of-care lung ultrasonography test performance characteristics, with chest radiography as a reference standard. RESULTS: Point-of-care lung ultrasonography was performed on 191 SCD patients with a mean age of 8 years; 41% were female patients, and there was a 17% prevalence of acute chest syndrome. Accuracy of point-of-care lung ultrasonography to detected acute chest syndrome was 92%, sensitivity was 88%, and specificity was 93% compared with that for chest radiography. CONCLUSION: Point-of-care lung ultrasonography is a feasible alternative to chest radiography for screening for acute chest syndrome in young patients with SCD. Further studies are needed to determine how this test performs within clinical practice.

RESUMEN

OBJECTIVE: To evaluate how inotropic requirements in neonates with respiratory failure are affected by extracorporeal membrane oxygenation (ECMO) mode and whether high requirements predict mortality. STUDY DESIGN: This retrospective chart review included all neonates undergoing ECMO for primary respiratory failure from 2010 to 2016 at a single institution. The vasoactive inotropy score (VIS) was calculated as described in the literature. Data were analyzed with descriptive statistics and univariate analyses. RESULTS: Of the 110 identified neonates, 96 underwent venovenous (VV) (87%), 11 (10%) venoarterial, and 3 (3%) converted from VV to venoarterial. The median precannulation VIS score was 33.02 for patients who underwent VV compared with 28.93 for venoarterial (P = .25) and 15 for infants converted. VIS decreased dramatically by 4 hours of ECMO in both groups. The VIS before cannulation was similar in survivors and nonsurvivors, but was significantly higher in nonsurvivors after 24 hours of ECMO (median VIS, 12 [IQR, 8-25] vs 8 [IQR, 3.0-14.5]; P = .035) and at decannulation (10 [IQR, 7-19] vs 3 [IQR, 0-7]; P < .001). CONCLUSIONS: Neonates with respiratory failure can be successfully managed on VV ECMO even with considerable vasoactive requirements. Vasoactive requirement after 24 hours of ECMO was predictive of mortality.
