Abstract
PURPOSE Children with congenital heart disease (CHD) from low- to middle-income countries (LMIC) are suspected to have a high prevalence of antibiotic-resistant microorganisms (ARMOs) carriage, but data are currently lacking. Carriage of ARMOs could impact the post-operative course in pediatric intensive care unit (PICU). The aim of the study was to assess the prevalence of ARMOs carriage in children with CHD from LMIC and its impact on post-operative outcomes. METHODS This was a retrospective monocentric study from 01/2019 to 12/2022. Included patients were children (0-18 years) from a LMIC admitted after CHD surgery and with AMRO screening performed the week before. Infections and post-operative evolution were compared based on ARMOs carriage status. FINDINGS Among 224 surgeries (median age 38.5 months (IQR 22-85.5)), ARMOs carriage was evidenced in 95 cases (42.4%). Main organisms isolated were Extended Spectrum Beta-Lactamase (ESBL) producing E. coli (75/224) 33.5%)) and ESBL-K. pneumoniae (30/224) 13.4%)). Median mechanical ventilation duration was 1 day (IQR 0-1), PICU stay 3 days (IQR 2-4) and hospital stay 6.5 days (IQR 5-10). A total of 17 infectious episodes occurred in 15 patients, mostly consisting in hospital-acquired pneumonia (HAP) (12/17). Only two infections were caused by a colonizing ARMO. Occurrence of infections and patients' outcome were similar between ARMO carriers and non-carriers. Higher use of carbapenems (6 (6.3%) vs 1 (0.8%), p = 0.04) and a trend to a higher use of vancomycin (14 (13.7%) vs 9 (6.9%), p = 0.04) in case of ARMOs carriage. Applying current guidelines, negative swab screening could have led to sparing most of empirical vancomycin therapy (11/12) for HAP based on current guidelines. CONCLUSION Prevalence of AMROs carriage is high in children from LMIC and has a limited impact on patients' outcome. However, ARMOs carriage leads to higher consumption of antibiotics. Screening may help saving use of broad-spectrum antibiotic in non-carrier patients.

Total face mask with neurally adjusted ventilatory assist as a rescue therapy in infants with severe bronchiolitis. Eur J Pediatr 2024:10.1007/s00431-024-05543-1. [PMID: 38581463 DOI: 10.1007/s00431-024-05543-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 03/23/2024] [Accepted: 03/26/2024] [Indexed: 04/08/2024]
Abstract
Severe bronchiolitis patients are often supported with non-invasive ventilation (NIV). In case of NIV failure, we recently started to use non-invasive neurally adjusted ventilatory assist ventilation (NIV-NAVA) with a total face mask interface (TFM) and report now our experience with this modality of respiratory support. Retrospective study was made from October 2022 to May 2023 at the Geneva University Hospital Paediatric Intensive Care Unit. Inclusion criteria were children, aged from 0 to 6 months, with severe bronchiolitis with initial NIV failure and switch to NIV-NAVA-TFM. From 49 children with respiratory syncytial virus (RSV)-induced bronchiolitis requiring any form of respiratory support, 10 (median age 61 days (IQR 44-73) failing CPAP or NIV underwent rescue treatment with NIV-NAVA using a TFM. Patients were switched to TFM-NIV-NAVA 8 h (IQR 3-22) after admission for 24.5 h (IQR 13-60). After initiation of TFM-NIV-NAVA, oxygenation improved significantly as early as 1 h after initiation, whereas transcutaneous CO2 values remained stable. None of the patients needed to be intubated and there was no episode of TFM discontinuation due to interface discomfort or other unwanted side effects. Sedation was used in all patients with high proportion of intravenous dexmedetomidine. Median ventilatory assistance duration was 2.5 days (IQR 2-4) and median PICU stay was 4.5 (IQR 3-6). Conclusion: In infants with severe RSV-induced bronchiolitis, respiratory support with TFM-NIV-NAVA seems to be feasible as a rescue therapy and might be considered in selected patients. What is Known: • Bronchiolitic patients with NIV support failure may require invasive mechanical ventilation. • Interface related complications, especially facial sores, can be a cause of NIV failure. What is New: • Total face mask with non-invasive neurally adjusted ventilatory assist (TFM-NIV-NAVA) seems feasible as a rescue therapy in deteriorating patients with CPAP or NIV failure. • TFM-NIV-NAVA can improve oxygenation rapidly in patients with aggravating hypoxemia and seems to be well tolerated.

Abstract
There are minimal data describing use of extracorporeal membrane oxygenation (ECMO) in pediatric patient after a liver transplantation (LT). This study aimed at describing ECMO run in this specific situation using the data from Extracorporeal Life Support Organization (ELSO) Registry between January 1, 2010, to December 31, 2022. We described patients' characteristics at ECMO initiation, outcome and mortality risk factors. We identified 27 patients with a median age of 2.7 years (interquartile range (IQR) = 1.5-9.9). Main indication for ECMO support was respiratory (14/27 [52%]) followed by extracorporeal cardiopulmonary resuscitation (ECPR) (7/27 [26%]) and cardiac (6/27 [22%]). Overall in-hospital mortality was 63% (17/27). Mortality rate according to ECMO indications was 50% for both respiratory and cardiac failure and reached 100% for ECPR patients. Overall, nonsurvivors experienced significantly more complications under ECMO support (p = 0.007). Main on-ECMO complications were hemorrhagic (11/27 [41%]) and thrombotic (7/27 [26%]). No clinical or biologic factors was predictive of patients' outcome. Our results suggest that ECMO support is a viable option for cardiac and respiratory indications after pediatric LT. Occurrence of complications while on ECMO are associated with unfavorable outcomes. The extremely high mortality rate in ECPR patients merits further research.

Abstract
OBJECTIVES To determine factors associated with brain death in children treated with extracorporeal cardiopulmonary resuscitation (E-cardiopulmonary resuscitation). DESIGN Retrospective database study. SETTINGS Data reported to the Extracorporeal Life Support Organization (ELSO), 2017-2021. PATIENTS Children supported with venoarterial extracorporeal membrane oxygenation (ECMO) for E-cardiopulmonary resuscitation. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS Data from the ELSO Registry included patient characteristics, blood gas values, support therapies, and complications. The primary outcome was brain death (i.e., death by neurologic criteria [DNC]). There were 2,209 children (≥ 29 d to < 18 yr of age) included. The reason for ECMO discontinuation was DNC in 138 patients (6%), and other criteria for death occurred in 886 patients (40%). Recovery occurred in 1,109 patients (50%), and the remaining 76 patients (4%) underwent transplantation. Fine and Gray proportional subdistribution hazards' regression analyses were used to examine the association between variables of interest and DNC. Age greater than 1 year ( p < 0.001), arterial blood carbon dioxide tension (Pa co2 ) greater than 82 mm Hg ( p = 0.022), baseline lactate greater than 15 mmol/L ( p = 0.034), and lactate 24 hours after cannulation greater than 3.8 mmol/L ( p < 0.001) were independently associated with greater hazard of subsequent DNC. In contrast, the presence of cardiac disease was associated with a lower hazard of subsequent DNC (subdistribution hazard ratio 0.57 [95% CI, 0.39-0.83] p = 0.004). CONCLUSIONS In children undergoing E-cardiopulmonary resuscitation, older age, pre-event hypercarbia, higher before and during ECMO lactate levels are associated with DNC. Given the association of DNC with hypercarbia following cardiac arrest, the role of Pa co2 management in E-cardiopulmonary resuscitation warrants further studies.

Abstract
Inhaled nitric oxide (iNO) is a pulmonary vasodilator that plays an important clinical ICU role. The administration of iNO is usually performed through an endotracheal tube, but spontaneously breathing patients might also benefit from iNO administration. The use of the non-invasive administration of iNO through high-flow nasal cannula (HFNC) allows for NO delivery in spontaneously breathing patients who still need supplemental oxygen and positive airway pressure. A simple method to administer NO through HFNC is described here using standard commercially available NO administration and HFNC.

Abstract
Perfluorocarbons (PFCs) are organic liquids derived from hydrocarbons in which some of the hydrogen atoms have been replaced by fluorine atoms. They are chemically and biologically inert substances with a good safety profile. They are stable at room temperature, easy to store, and immiscible in water. Perfluorocarbons have been studied in biomedical research since 1960 for their unique properties as oxygen carriers. In particular, PFCs have been used for liquid ventilation in unusual environments such as deep-sea diving and simulations of zero gravity, and more recently for drug delivery and diagnostic imaging. Additionally, when delivered as emulsions, PFCs have been used as red blood cell substitutes. This narrative review will discuss the multifaceted utilization of PFCs in therapeutics, diagnostics, and research. We will specifically emphasize the potential role of PFCs as red blood cell substitutes, as airway mechanotransducers during artificial placenta procedures, as a means to improve donor organ perfusion during the ex vivo assessment, and as an adjunct in cancer therapies because of their ability to reduce local tissue hypoxia.

Abstract
Shock is a life-threatening condition, and its timely recognition is essential for adequate management. Pediatric patients with congenital heart disease admitted to a cardiac intensive care unit (CICU) after surgical corrections are particularly at risk of low cardiac output syndrome (LCOS) and shock. Blood lactate levels and venous oxygen saturation (ScVO2) are usually used as shock biomarkers to monitor the efficacy of resuscitation efforts, but they are plagued by some limitations. Carbon dioxide (CO2)-derived parameters, namely veno-arterial CO2 difference (ΔCCO2) and the VCO2/VO2 ratio, may represent a potentially valuable addition as sensitive biomarkers to assess tissue perfusion and cellular oxygenation and may represent a valuable addition in shock monitoring. These variables have been mostly studied in the adult population, with a strong association between ΔCCO2 or VCO2/VO2 ratio and mortality. In children, particularly in CICU, few studies looked at these parameters, while they reported promising results on the use of CO2-derived indices for patients' management after cardiac surgeries. This review focuses on the physiological and pathophysiological determinants of ΔCCO2 and VCO2/VO2 ratio while summarizing the actual state of knowledge on the use of CO2-derived indices as hemodynamical markers in CICU.

Abstract
BACKGROUND The benefits of facilitating breastmilk feeding and close contact between mother and neonate (family-centred care; FCC) in the perinatal period are well-established. The aim of this study was to determine how the delivery of FCC practices were impacted for neonates born to mothers with perinatal SARS-CoV-2 infection during the COVID-19 pandemic. METHODS Neonates born to mothers with confirmed SARS-CoV-2 infection during pregnancy were identified from the 'EsPnIC Covid paEdiatric NeonaTal REgistry' (EPICENTRE) multinational cohort between 10 March 2020 and 20 October 2021. The EPICENTRE cohort collected prospective data on FCC practices. Rooming-in and breastmilk feeding practice were the main outcomes, and factors influencing each were determined. Other outcomes included mother-baby physical contact prior to separation and the pattern of FCC components relative to time and local site guidelines. FINDINGS 692 mother-baby dyads (13 sites, 10 countries) were analysed. 27 (5%) neonates were positive for SARS-CoV-2 (14 (52%) asymptomatic). Most sites had policies that encouraged FCC during perinatal SARS-CoV-2 infection for most of the reporting period. 311 (46%) neonates roomed-in with their mother during the admission. Rooming-in increased over time from 23% in March-June 2020 to 74% in January-March 2021 (boreal season). 330 (93%) of the 369 separated neonates had no FCC physical contact with their mother prior, and 319 (86%) were asymptomatic. Maternal breastmilk was used for feeding in 354 (53%) neonates, increasing from 23% to 70% between March-June 2020 and January-March 2021. FCC was most impacted when mothers had symptomatic COVID-19 at birth. INTERPRETATION This is the largest report of global FCC practice during the COVID-19 pandemic to date. The COVID-19 pandemic may have impacted FCC despite low perinatal transmission rates. Fortunately, clinicians appear to have adapted to allow more FCC delivery as the COVID-19 pandemic progressed.

Abstract
The population of patients with congenital heart disease is constantly growing with an increasing number of individuals reaching adulthood. A significant proportion of these children and young adults will suffer from tachyarrhythmias due to the abnormal anatomy, the hemodynamic burden, or as a sequela of surgical treatment. Depending on the underlying mechanism, arrhythmias may arise in the early postoperative period (hours to days after surgery) or in the late postoperative period (usually years after surgery). A good understanding of the electrophysiological characteristics and pathophysiological mechanisms is therefore crucial to guide the therapeutic approach. Here, we synthesize the current state of knowledge on epidemiological features, risk factors, pathophysiological insights, electrophysiological features, and therapy regarding tachyarrhythmias in children and young adults undergoing reparative surgery for congenital heart disease. The evolution and latest data on treatment options, including pharmacological therapy, ablation procedures, device therapy decision, and thromboprophylaxis, are summarized. Finally, throughout this comprehensive review, knowledge gaps and areas for future research are also identified.

Abstract
Background Left atrial (LA) decompression on extracorporeal membrane oxygenation (ECMO) can reduce left ventricular distension, allowing myocardial rest and recovery, and protect from lung injury secondary to cardiogenic pulmonary edema. However, clinical benefits remain unknown. We sought to evaluate the association between LA decompression and in-hospital adverse outcome (mortality, transplant on ECMO, or conversion to ventricular assist device) in patients who failed to wean from cardiopulmonary bypass using a propensity score to adjust for baseline differences. Methods and Results Children (aged <18 years) with biventricular physiology supported with ECMO for failure to wean from cardiopulmonary bypass after cardiac surgery from 2000 through 2016, reported to the ELSO (Extracorporeal Life Support Organization) Registry, were included. Inverse probability of treatment weighted logistic regression was used to test the association between LA decompression and in-hospital adverse outcomes. Of the 2915 patients supported with venoarterial ECMO for failure to wean from cardiopulmonary bypass, 1508 had biventricular physiology and 279 (18%) underwent LA decompression (LA+). Genetic and congenital abnormalities (P=0.001) and pulmonary hypertension (P=0.010) were less frequent and baseline arrhythmias (P=0.022) were more frequent in LA+ patients. LA+ patients had longer pre-ECMO mechanical ventilation and CBP time (P<0.001), and used aortic cross-clamp (P=0.001) more frequently. Covariates were well balanced between the propensity-weighted cohorts. In-hospital adverse outcomes occurred in 47% of LA+ patients and 51% of the others. Weighted multivariate logistic regression showed LA decompression to be protective for in-hospital adverse outcomes (adjusted odds ratio, 0.775 [95% CI, 0.644-0.932]). Conclusions LA decompression independently decreased the risk of in-hospital adverse outcome in pediatric venoarterial ECMO patients who failed to wean from cardiopulmonary bypass, suggesting that these patients may benefit from LA decompression.

Abstract
INTRODUCTION Congenital heart disease (CHD) is the most frequent birth defect. As survival has significantly improved, attention has turned to neurodevelopmental outcomes of children undergoing heart surgery in early infancy. Since multiple risk factors contribute to neurodevelopmental alterations, a nationwide registry collecting data on medical characteristics, interventions, clinical course and neurodevelopment until school-age is needed to improve the quality of management, identify risk- and protective factors affecting neurodevelopment, and facilitate multicentre trials. METHODS AND ANALYSIS The Swiss Outcome Registry for CHIldren with severe congenital heart Disease (ORCHID) is a nationwide, prospective, population-based patient registry developed (1) to collect baseline characteristics and clinical data of CHD patients operated with bypass-surgery or hybrid procedures in the first 6 weeks of life in Switzerland, (2) to monitor long-term neurodevelopment, and (3) to relate clinical characteristics and neurodevelopment to identify risk and protective factors in these children. This registry started data collection relating to pregnancy, birth, preoperative course, catheter-based and surgical treatment, postoperative course and reinterventions in 2019. The primary outcome includes standardised neurodevelopmental assessments at 9 to 12 months, 18 to 24 months and 5.5 to 6 years. We expect to include 80 to 100 children per year. Correlation and regression analyses will be used to investigate risk- and protective factors influencing neurodevelopment. ETHICS AND DISSEMINATION OF RESULTS Swiss ORCHID received support by the Accentus Charitable Foundation, the Anna Mueller Grocholoski Stiftung, the Swiss Society of Paediatric Cardiology, the Verein Kinderherzforschung, and the Corelina - Stiftung für das Kinderherz, and was approved by the cantonal ethics committees. Findings will be presented at national and international scientific meetings, and published in peer-reviewed journals. Results will also be shared with patient organizations, primary health care providers, and public health stakeholders to ensure a widespread dissemination of the results.

Abstract
Purpose: Music therapy intervention (MT) could be used as an adjunctive therapy in PICU for anxiety and pain management. The aim of the study was to examine the perception of MT by children’s parents in a PICU of a tertiary care teaching hospital. Methods: This is a retrospective cohort study summarizing the results of an institutional quality improvement initiative. Questionnaires were distributed to parents whose children were exposed to MT. Results: From April 2019 to July 2021, 263 patients received a total of 603 h of MT. Twenty-five questionnaires were distributed to parents over a 4-month period (February–June 2021). A total of 19 (76%) parents completed the questionnaire. The majority of parents thought that MT helped their child to communicate (89%), feel less isolated (100%) and cope with stress during hospitalization (100%). The majority of parents also thought that MT contributed to physical recovery (90%) and alleviated feelings of anxiety (90%). Parents also believed that MT should be offered as an out-patient service. Conclusions: Our study agrees with other studies on the positive potentials of MT in PICU. Music therapy intervention could be used to promote children’s and parents’ psychological well-being. Further studies are warranted to evaluate the impact of MT on long-term post-ICU outcomes.

In situ simulation training for parental presence during critical situations in PICU: an observational study. Eur J Pediatr 2022; 181:2409-2414. [PMID: 35277736 PMCID: PMC9110492 DOI: 10.1007/s00431-022-04425-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 02/02/2022] [Accepted: 02/18/2022] [Indexed: 02/02/2023]
Abstract
Family presence during invasive procedures or cardiopulmonary resuscitation (CPR) is a part of the family-centered approach in pediatric intensive care units (PICUs). We established a simulation program aiming at providing communication tools to healthcare professionals. The goal of this study was to evaluate the impact of this program on the stress of PICU professionals and its acceptance. An observational study of a simulation program, with questionnaire, was used to measure pre- and post-simulation stress and the degree of satisfaction of the participants. PICU of Geneva Children's Hospital, Switzerland. Forty simulations with four different simulation scenarios and various types of parental behavior, as imitated by professional actors, were completed during a 1-year period. Primary outcomes were the difference in perceived stress level before and after the simulation and the degree of satisfaction of healthcare professionals (nursing assistants, nurses, physicians). The impact of previous experience with family members during critical situations or CPR was evaluated by variation in perceived stress level. Overall, 201 questionnaires were analyzed. Perceived stress associated with parental presence decreased from a pre-simulation value of 6 (IQR, 4-7) to 4 (IQR, 2-5) post-simulation on a scale of 1-10. However, in 25.7% of cases, the individually perceived post-simulation stress level was higher than the pre-simulation one. Satisfaction of the participants was high with a median of 10 (IQR, 9-10) out of 10. CONCLUSIONS A simulation program helps reduce PICU team emotional stress associated with the presence of family members during critical situations or CPR, and is welcomed by PICU team members. WHAT IS KNOWN • Family presence during cardiopulmonary resuscitation (CPR) or critical situations is a part of the family-centered approach in pediatric intensive care. • The benefits for the family have been already demonstrated. However, this policy is still controversy among healthcare professionals. WHAT IS NEW • A simulation program seeking to provide skills focused on family presence management in the PICU is useful to reduce stress and was well accepted by participants. • It might become an indispensable training intervention for the implementation of a PICU policy to allow family presence during CPR or other critical situations.

Abstract
The aim of this study was to evaluate the impact of pre-extracorporeal membrane oxygenation (ECMO) ventilatory parameters with in-hospital mortality in children with pediatric acute respiratory distress syndrome undergoing ECMO for respiratory indication. In this retrospective analysis of the Extracorporeal Life Support Organization (ELSO) Registry, all pediatric patients (≥29 days to ≤18 years) who required ECMO for respiratory indications were screened. The primary outcome was in-hospital mortality. From 2013 to 2017, 2,727 pediatric ECMO runs with a respiratory indication were reported to the ELSO registry. Overall mortality was 37%. Oxygenation Index (OI) and duration of mechanical ventilation (MV) before ECMO deployment were both independently associated with in-hospital mortality. No threshold effect for OI was observed. Pre-ECMO positive end-expiratory pressure and delta pressure levels were respectively lower and higher than recommended. Mortality rates for OI values between 4 and 60 and above oscillated between 32% and 45%. Children within a wider range of pre-ECMO OI (either below or above 40) might be considered as reasonable candidates for ECMO deployment. Larger, prospective multicenter studies to confirm the discriminatory ability of OI are warranted.

Aortic valve neocuspidalization in paediatric patients with isolated aortic valve disease: early experience. Interact Cardiovasc Thorac Surg 2021; 32:111-117. [PMID: 33221849 DOI: 10.1093/icvts/ivaa237] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 08/21/2020] [Accepted: 09/16/2020] [Indexed: 12/17/2022] Open
Abstract
OBJECTIVES There is growing interest in the aortic valve (AV) neocuspidalization technique for the treatment of aortic valve disease (AVD). We report our medium-term results with this procedure performed in a paediatric patient population. METHODS Between July 2016 and May 2020, 22 patients with both congenital and acquired isolated AVD were treated with neocuspidalization. The primary outcome was progression of the preoperatively assessed AVD in the immediate postoperative course and at follow-up. Secondary outcome was freedom from reintervention by material used. Potential predictors of failure were analysed in relation to the primary outcome. RESULTS The median age at operation was 13.9 (interquartile range, 9.8-16.2) years, and the prevailing AV defect was stenosis in 10 cases (45%) and incompetence in 12 (55%). Pre-treated autologous pericardium was used in 13 patients whereas bovine pericardium in 9. Effective treatment of AV stenosis or regurgitation was achieved and remained stable over a median follow-up of 11.3 (4.7-21) months. Three patients required AV replacement at 4.9, 3.5 and 33 months. At follow-up, an upward trend of both median indexed vena contracta jet widths and aortic peak and mean gradients were recorded, the latter associated with a failure to grow the aortic annulus. Predictor of such outcome turned out to be the use of bovine pericardium. A significant inverse linear correlation between AV peak gradient at follow-up and preoperative aortic annular size (P = 0.008) was also demonstrated. CONCLUSIONS The Ozaki procedure is safe and effective in paediatric patients with AV disease. The use of heterologous pericardium should probably be minimized. Moreover, preoperative small aortic annuli should probably be promptly treated by means of an associated ring enlargement procedure.

Comparison of inspiratory effort with three variable-flow nasal continuous positive airway pressure devices in preterm infants: a cross-over study. Arch Dis Child Fetal Neonatal Ed 2021; 106:404-407. [PMID: 33452219 PMCID: PMC8237202 DOI: 10.1136/archdischild-2020-320531] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 11/25/2020] [Accepted: 12/08/2020] [Indexed: 11/25/2022]
Abstract
OBJECTIVE Patient's work of breathing may vary between different neonatal nasal continuous positive airway pressure (NCPAP) devices. Therefore, we aimed to compare the inspiratory effort of three variable-flow NCPAP delivery systems used in preterm infants. DESIGN Cross-over study. PATIENTS/SETTING From June 2015 to August 2016, 20 preterm infants weighing ≤2500 g requiring NCPAP for mild respiratory distress syndrome were enrolled. INTERVENTIONS Each patient was successively supported by three randomly assigned variable-flow NCPAP systems (MedinCNO, Infant Flow and Servo-i) for 20 min while maintaining the same continuous positive airway pressure level as the patient was on before the study period. MAIN OUTCOME MEASURES Patients' inspiratory effort was estimated by calculating the sum of the difference between maximal inspiratory and baseline electrical activity of the diaphragm (∆EAdi) for 30 consecutive breaths, and after normalising this obtained value for the timing of the 30 breaths. RESULTS Physiological parameters (oxygen saturation measured by pulse oximetry, respiratory rate, heart beat, transcutaneous partial pressure CO2) and oxygen requirements remained identical between the three NCPAP systems. Although a wide variability in inspiratory effort could be observed, there were no statistically significant differences between the three systems for the sum of ∆EAdi for 30 breaths: CNO, 262 (±119) µV; IF, 352 (±262) µV; and SERVO-i, 286 (±126) µV, and the ∆EAdi reported on the timing of 30 breaths (sum ∆EAdi/s): CNO, 6.1 (±2.3) µV/s; IF, 7.9 (±4.9) µV/s; SERVO-i, 7.6 (±3.6) µV/s. CONCLUSION In a neonatal population of preterm infants, inspiratory effort is comparable between the three tested modern variable-flow NCPAP devices.

Aortic Valve Neocuspidalization May Be a Viable Alternative to Ross Operation in Pediatric Patients. Pediatr Cardiol 2021; 42:668-675. [PMID: 33394106 PMCID: PMC7780600 DOI: 10.1007/s00246-020-02528-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Accepted: 12/18/2020] [Indexed: 10/28/2022]
Abstract
The aim of the study was to evaluate the medium-term results of aortic valve neocuspidalization according to Ozaki compared to Ross procedure for treatment of isolated aortic valve disease in pediatric age. Thirty-eight consecutive patients with congenital or acquired aortic valve disease underwent either Ozaki (n = 22) or Ross (n = 16) operation between 01/2015 and 05/2020. The primary outcome was progression of aortic valve disease and aortic ring and root dimension, whereas secondary outcome was freedom from reintervention or death by type of operation. Median age was 12.4 (8.8-15.8) years and the prevailing lesion was stenosis in 20 cases (52%) and incompetence in 18 (48%). One death occurred in the Ross group in the early postoperative period, while there were no deaths in the Ozaki group. Effective treatment of aortic valve stenosis or regurgitation occurred in both groups and remained stable over a median follow-up of 18.2 (5-32) months. In Ozaki group, 3 patients required aortic valve replacement at 4.9, 3.5, and 33 months, respectively. In Ross group, 1 patient required Melody pulmonary valve replacement, whereas none required aortic valve surgery. Finally, significantly higher aortic transvalvular gradient at follow-up was recorded in Ozaki group compared to Ross group. Overall, there was no significant difference in freedom from reoperation or death between the two groups. The medium-term outcome of Ozaki and Ross in pediatric patients is similar, despite an increased tendency of the former to develop aortic transvalvular gradient in the follow-up. Future larger multicenter studies with longer follow-up are warranted to confirm these results.

Abstract
Pediatric Index of Mortality (PIM) 2 score is used in pediatric intensive care unit (PICU) to predict the patients' risk of death. The performance of this model has never been assessed in Switzerland. The aim of this study was to evaluate the performance of the PIM2 score in the whole cohort and in pre-specified diagnostic subgroups of patients admitted to PICUs in Switzerland. All children younger than 16 years admitted to any PICU in Switzerland between January 1, 2012 and December 31, 2017 were included in the study. A total of 22,382 patients were analyzed. Observed mortality was 2%, whereas mortality predicted by PIM2 was 4.2% (SMR = 0.47, 95% CI, 0.42-0.52). Calibration was also poor across the deciles of mortality risks (p < 0.001). The AUC-ROC for the entire cohort was 0.88 (95% CI, 0.87-0.90). Calibration varied significantly according to primary diagnosis.Conclusion: The performance of the PIM 2 score in a cohort of Swiss patients is poor with adequate discrimination and poor calibration. The PIM 2 score tends to under predict the number of deaths among septic patients and in patients admitted after a cardiorespiratory arrest. What is Known: •PIM2 score is a widely used mortality prediction model in PICU. •PIM2 performance among uncommon but clinically relevant diagnostic subgroups of patients is unknown. •The performance of PIM2 score has never been assessed in Switzerland. What is New: •The performance of the PIM 2 score in a cohort of Swiss patients is poor with adequate discrimination and poor calibration. •Calibration varies significantly according to primary diagnosis. The PIM 2 score under predict the number of deaths among septic patients and in patients admitted after a cardiorespiratory arrest.

Abstract
OBJECTIVES To make recommendations on improving understanding of bleeding and thrombosis with pediatric extracorporeal life support including future research directions. DATA SOURCES Evaluation of literature and consensus conferences of pediatric critical care and extracorporeal life support experts. STUDY SELECTION A team of 10 experts with pediatric cardiac and extracorporeal membrane oxygenation experience and expertise met through the Pediatric Cardiac Intensive Care Society to review current knowledge and make recommendations for future research to establish "best practice" for anticoagulation management related to extracorporeal life support. DATA EXTRACTION/DATA SYNTHESIS This white paper focuses on clinical understanding and limitations of current strategies to monitor anticoagulation. For each test of anticoagulation, limitations of current knowledge are addressed and future research directions suggested. CONCLUSIONS No consensus on best practice for anticoagulation monitoring exists. Structured scientific evaluation to answer questions regarding anticoagulation monitoring and bleeding and thrombotic events should occur in multicenter studies using standardized approaches and well-defined endpoints. Outcomes related to need for component change, blood product administration, healthcare outcome, and economic assessment should be incorporated into studies. All centers should report data on patient receiving extracorporeal life support to a registry.

Abstract
Aims To stipulate a new definition for long-stay patients (LSPs) in pediatric intensive care unit (PICU). We defined LSPs as the 10% of patients with the longest PICU length-of-stay (LOS) for each age and diagnostic group. To assess whether the thresholds (days of PICU stay) for the definition of LSPs in PICU significantly differ among diagnostic and age categories. To determine whether independent associations exist between patients’ characteristics at admission and LSPs diagnosis in pre-specified diagnostic and age groups. Methods This was a multicenter retrospective cohort study including all PICUs in Switzerland. Multivariable regression analysis was used to seek for association between patients’ variables at admission and LSPs Results We included 22,284 patients with a median (IQR) age of 12 (1–84) months. Significantly different thresholds across diagnostic and age subgroups are identified. Readmission to PICU, higher PIM2 and NEMS (a score used to quantify nursing workload at intensive care unit level) at admission were associated with higher likelihood of becoming LSPs. Conclusions Our results showed a significantly different definitions of LSPs for specific diagnoses and age categories. Readmission to PICU and higher acuity at admission are associated with longer PICU length-of-stay in the majority of diagnostic groups. A more personalized definition of LSPs in children based on actual patients’ characteristics should probably be used in an effort to optimize care and reduce costs.

Abstract
BACKGROUND The purpose of this study was to identify predictors of postoperative respiratory failure after surgical tracheoplasty for congenital tracheal stenosis. METHODS Between February 2011 and April 2017, 16 infants underwent congenital tracheal stenosis repair. Preoperative computed tomography evaluation of the trachea and mainstem bronchi was performed. The primary outcome was midterm freedom from postoperative respiratory failure defined as persistent need for mechanical ventilation or surgical tracheobronchial reoperation. Bronchial mismatch, defined as [1 - (smaller bronchus diameter / larger bronchus diameter)] × 100, was analyzed in relation to the primary outcome. RESULTS Median age was 106 days (range, 1 to 406) and median weight was 5.3 kg (range, 2.6 to 8 kg). Four patients were neonates (25%) and 6 had genetic abnormalities (37.5%). There were no early nor late deaths. Median ventilation time was 5.5 days (range, 3 to 45). Mean follow-up time was 2.2 years (range, 0.1 to 4.5). Four patients with bronchial mismatch greater than 20% had postoperative respiratory failure (p = 0.002). Two of them underwent tracheostomy and were discharged with ventilation home care support. One underwent successful reoperation consisting of bilateral bronchial plasty with autologous cartilage rib grafts, and the other underwent successful right bronchial and tracheal reconstruction. One patient with bilateral bronchial hypoplasia underwent slide tracheoplasty associated with preemptive bilateral bronchial plasty and made a full recovery. CONCLUSIONS Surgical treatment of congenital tracheal stenosis in neonates and infants portends a good outcome. Bronchial mismatch greater than 20% can identify a subset of patients at increased risk for surgical reintervention and chronic respiratory failure. Slide tracheoplasty with preemptive bronchial reconstruction may prevent postoperative respiratory failure.

Abstract
Objective To report a case of a newborn patient with renal failure due to polycystic kidneys requiring renal replacement therapy, and total anomalous pulmonary venous return requiring major cardiosurgical intervention. Setting Pediatric cardiosurgery operatory room and pediatric cardiologic intensive care. Patient: A 6-day-old newborn child weighing 3.1 kg. Results Renal function (creatinine value and urine output) was monitored during the course of the operation and intraoperative renal replacement therapy was not initiated. Serum creatinine concentration decreased from 4.4 to 3 mg/dL at cardiopulmonary bypass (CPB) start and to 1.5 at the end of surgery: the creatinine decrease was provided by the dilutional effect of CPB priming and the infusion of fresh blood from transfusions together with an adequate filtration rate (800 m/L in about 120 minutes). After the operation, extracorporeal membrane oxygenation (ECMO) for ventricular dysfunction and continuous hemofiltration for anuria refractory to medical therapy were prescribed. The hemofiltration machine was set in parallel with the ECMO machine at a blood flow rate of 60 ml/min and a predilution replacement solution infusion of 600 ml/h (4.5 ml/min of creatinine clearance once adjusted on extracorporeal circuits; 3000 mL/m2 hemofiltration): after a single hemofiltration session lasting 96 hours, serum creatinine reached optimal steady state levels around 0.5 mg/dL on postoperative day 2 and 3. Conclusion Administration of intraoperative continuous hemofiltration is not mandatory in the case of a 3-kg newborn patient with established renal failure needing major cardiosurgery: hemodilution secondary to CPB, transfusion of hemoderivates, and optimal UF rate appear to be effective methods for achieving solute removal. If postoperative continuous hemofiltration is started, however, a “dialytic dose” of 4.5 ml/min allows an adequate creatinine clearance, quick achievement of a steady state of serum creatinine concentration and an eventual acceptable rate of inflammatory mediator removal.

Abstract
AIM The combination of hydrocortisone and fludrocortisone improved outcomes in septic shock. However, the specific role of fludrocortisone remains controversial and its pharmacokinetics (PK) has never been investigated in septic shock. This study aimed at characterizing the PK of fludrocortisone in septic shock. METHODS This was a single-centre ancillary PK study of a large multinational trial of crystalloids versus colloids for acute hypovolemia in intensive care unit (ICU) patients. In 21 adults with septic shock, fludrocortisone plasma concentrations were measured by liquid chromatography-mass spectrometry tandem analysis, before and repeatedly until 18 h after an oral dose of 50 μg. PK parameters were estimated using a nonlinear mixed-effects modelling. RESULTS Undetectable plasma concentrations were observed in 7 out of 21 patients. In the remaining 14 patients, plasma fludrocortisone concentrations were best described by a one-compartmental model with first-order absorption, a lag time (Tlag ) before the absorption phase, and first-order elimination. Severity of illness, as quantified by Simplified Acute Physiology Score II, significantly increased Tlag and apparent clearance. There was a large inter-individual variability in PK parameters. The population estimates of PK parameters (inter-individual variability) were: Tlag 0.65 h (98%), apparent clearance 40 l h-1 (49%) and apparent volume of distribution 78 l (75%). Plasma half-life was estimated at 1.35 h (95% CI, 0.84-2.03) and area under the curve of plasma concentrations was estimated at 1.25 μg h l-1 (95% CI, 1.09-1.46). CONCLUSIONS A single oral dose of fludrocortisone yielded undetectable plasma concentrations in one-third of adults with septic shock. Fludrocortisone PK showed a short plasma elimination half-life and a large inter-individual variability.

Abstract
BACKGROUND Little is known about practitioner preference, the availability of technology, and variability in practice with respect to hemodynamic monitoring and vasoactive drug use after congenital heart surgery. The aim of this study was to characterize current hospital practices related to the management of low cardiac output syndrome (LCOS) across Italy. METHODS We issued a 22-item questionnaire to 14 Italian hospitals performing pediatric cardiac surgery. RESULTS Electrocardiogram, invasive blood pressure, central venous pressure, pulse oximetry, diuresis, body temperature, arterial lactate, and blood gas analysis were identified as routine in hemodynamic monitoring. With regard to advanced hemodynamic monitoring, pulmonary arterial catheter and transpulmonary thermodilution were available in 43% of the centers, uncalibrated pulse contour methods in 29% of the centers, and transesophageal/transthoracic echocardiograms in all of the centers. Dopamine added to milrinone was the most frequent drug regimen for LCOS prevention after cardiopulmonary bypass. Overall, 86% of centers used milrinone alone as the initial treatment for LCOS with elevated systemic vascular resistances and levosimendan, the second preferred choice. In cases of LCOS with low vascular resistance, epinephrine was the first choice (10 centers), dopamine was the second choice (4 centers), followed by vasopressin and norepinephrine (3 centers). For treatment of LCOS with elevated pulmonary resistances, milrinone was the first choice (eight centers), followed by inhaled nitric oxide (five centers). CONCLUSIONS The survey shows that advanced hemodynamic monitoring is rarely performed. The most commonly used vasoactive drugs are milrinone, levosimendan, dopamine, epinephrine, vasopressin, and norepinephrine. Guidelines on the topic are warranted.

Abstract
BACKGROUND It is currently uncertain which hemodynamic monitoring device reliably measures stroke volume and tracks cardiac output changes in pediatric cardiac surgery patients. OBJECTIVE To evaluate the difference between stroke volume index (SVI) measured by pressure recording analytical method (PRAM) and bioreactance and their ability to track changes after a therapeutic intervention. METHODS A single-center prospective observational cohort study in children undergoing cardiac surgery with cardiopulmonary bypass (CPB) was conducted. Twenty children below 20 kg with median (interquartile range) weight of 5.3 kg (4.1-7.8) and age of 6 months (3-20) were enrolled. Data were collected after anesthesia induction, at the end of CPB, before fluid administration and after fluid administration. Overall, median-IQR PRAM SVI values (23 ml·m(-2), 19-27) were significantly higher than bioreactance SVI (15 ml·m(-2), 12-25, P = 0.0001). Correlation (r(2) ) between the two methods was 0.15 (P = 0.0003). The mean difference between the measurements (bias) was 5.7 ml·m(-2) with a standard deviation of 9.6 (95% limits of agreement ranged from -13 to 24 ml·m(-2)). Percentage error was 91.7%. Baseline SVI appeared to be similar, but PRAM SVI was systematically greater than bioreactance thereafter, with the highest gap after the fluid loading phase: 13 (12-18) ml·m(-2) vs. 23 (19-25) ml·m(-2), respectively, P = 0.0013. A multivariable regression model showed that a significant independent inverse correlation with patients' body weight predicted the CI difference between the two methods after fluid challenge (β coefficient -0.12, P = 0.013). CONCLUSIONS Pressure recording analytical method and bioreactance provided similar SVI estimation at stable hemodynamic conditions, while bioreactance SVI values appeared significantly lower than PRAM at the end of CPB and after fluid replacement.

BACKGROUND AND AIM OF THE STUDY The study aim was to analyze the safety and longevity of cryopreserved homografts used for primary right ventricular outflow tract reconstruction (RVOTR), and to compare the outcome using either standard or bicuspidalized allografts. METHODS Between February 2000 and September 2014, a total of 53 patients underwent primary RVOTR using either a standard (n = 40) or a bicuspidalized (n = 13) cryopreserved homograft. The median age at surgery was 15.5 months (range: 1-419.06 months), and bodyweight was 8.5 kg (range: 4.1-71 kg). The median standard homograft size was 17.5 mm (range: 10-25 mm), while the median bicuspidalized homograft size was 16 mm (range: 14-22 mm). Follow up was complete in 91.4% of patients, with a median duration of 30.11 months (range: 0.26-161.26 months). Data analysis included primary diagnosis, type of surgery, age at surgery, size of conduit, need for reintervention, and survival. Predetermined primary outcomes were represented by survival and freedom from conduit reintervention. RESULTS Two patients with standard cryopreserved homograft died. during the early postoperative period (3.7%). No deaths were conduit-related. The five-year survival rate and ten-year freedom from reintervention were 91% (range: 74.7-97.2%) and 53.6% (range: 97-33.2%), respectively. RV-PA conduit replacement was performed in 14 patients (26.4%) at a median interval of 44.5 months (range: 14.93-162.46 months). Among these patients, four children (30.7%) received bicuspidalized homografts, and 10 (25%) received standard homografts. Causes of reintervention were conduit stenosis in six cases (43%), severe homograft valve regurgitation in two (14.2%), conduit stenosis and homograft valve regurgitation in two (14.2%), and stenosis of distal anastomosis involving pulmonary bifurcation in four (28.6%). Univariate analyses showed a longer freedom from reintervention for bicuspidalized compared to standard homograft (p = 0.03). CONCLUSION The results obtained suggested that bicuspidalized homograft performance compares well with that of standard allografts in terms of freedom from reintervention. Bicuspidalized homograft use is strongly indicated for primary RVOTR in small children, when a standard homograft of appropriate size is not available.

Abstract
OBJECTIVES The aim of this work was to evaluate the effect of long term supplementation with two moderate dose of Zn on plasma and cellular red-ox status markers in elderly volunteers. DESIGN, SETTING AND SUBJECTS In a double blind study 108 healthy volunteers, aged 70-85 years, were enrolled. They were randomly divided in 3 groups of treatment, receiving placebo, 15 mg/day and 30 mg/day of Zn for 6 months. Red-ox status markers were assessed at baseline and after 6 months evaluating carotenoids, vitamin A and E in plasma; glutathione (GSH), thiol groups (RSH), malondialdehyde (MDA), percentage of haemolysis and methemoglobin in erythrocytes. RESULTS Zn supplementation had no significant effects on red-ox status markers except for vitamin A levels (from 1.94±0.44 to 2.18±0.48 μM in volunteers receiving 15 mg of Zn and from 1.95±0.46 to 2.26±0.56 μM in volunteers receiving 30 mg of Zn), which increased proportionally to zinc dose. CONCLUSIONS It appears that, differently from unhealthy populations, long-term supplementation with two moderate doses of Zn in a healthy elderly population, with an adequate Zn nutritive status and macro and micronutrients intakes in the range of normality, is an inefficient way to increase antioxidant defences.

Abstract
This study aims at investigating the effect of an experimental period of intake of whole grain foods rich in lignans as part of an habitual diet on the plasma and urinary excretion of enterolignans, the biomarkers of lipid metabolism and the immunological and antioxidant status in a group of postmenopausal women with moderate serum cholesterol. A randomized double-blind crossover study was completed on 13 subjects in 12-weeks after protocol approval of an ethical committee. The subjects consumed whole grain foods high in lignans (30 g/d of breakfast cereals or biscuits, etc., 80 g/d of whole grain pasta) or refined grain foods for 4 weeks, separated by a 2-weeks wash-out period. A modest hypocholesterolemic effect (p < 0.05) of the whole grain diet was observed and the intake of whole grain products rich in lignans was also associated with an increase in urinary enterodiol excretion (p < 0.05).

Abstract
Bleeding during and after cardiac surgery is a major issue in pediatric patients. A prospective cohort study was conducted to evaluate the effect of a commercially available prothrombin complex (Confidex) administered in cardiac surgery after weaning from cardiopulmonary bypass of infants with nonsurgical bleeding. In this study, 14 patients younger than 1 year received a Confidex bolus and were matched with 11 patients of a similar age who did not receive the drug. The preoperative coagulation profile was similar in the two groups. No side effects, including anaphylaxis or thrombotic events, were observed. The numbers of units of packed red blood cells and fresh frozen plasma administered both intra- and postoperatively were similar. The postoperative coagulation examination results and thromboelastographic parameters did not differ significantly between the two groups. However, the Confidex patients bled significantly less than the control subjects during the first 24 postoperative hours. The median volume of drained blood was 0.0 ml/kg h (range 0-1.9 ml/kg h) compared with 1.9 ml/kg h (range 1-3 ml/kg h) (p = 0.009). At least one unit of packed red blood cells in the postoperative phase was required by 2 patients (14 %) in the Confidex group and six patients (54 %) in the control group (odds ratio [OR], 0.13; 95 % confidence interval [CI], 0.02-0.9; p = 0.03). The median duration of mechanical ventilation was 3 days (range 2-4 days) in the Confidex group and 4 days (range 0-8 days) in the control group (p = 0.66). The median stay in the intensive care unit was 6 days (range 5-9 days) in the Confidex group and 7 days (range 4-12 days) in the control group (p = 0.88). The use of Confidex for infants undergoing cardiac surgery was safe and effective. It reduced postoperative bleeding and allowed fewer units of packed red blood cells to be infused in the postoperative phase without major side effects.

Abstract
BACKGROUND AND AIMS Although sedentary behaviours are linked with mortality for cardiovascular reasons, it is not clear whether they are negatively related with cardio-metabolic risk factors. The aim was to examine the association between time engaged in television (TV) viewing or playing with videogames and a clustered cardio-metabolic risk in adolescents. METHODS AND RESULTS Sedentary behaviours and physical activity were assessed in 769 adolescents (376 boys, aged 12.5-17.5 years) from the HELENA-CSS study. We measured systolic blood pressure, HOMA index, triglycerides, TC/HDL-c, VO₂max and the sum of four skinfolds, and a clustered metabolic risk index was computed. A multilevel regression model (by Poisson) was performed to calculate the prevalence ratio of having a clustered metabolic risk. In boys, playing >4 h/day with videogames (weekend) and moderate to vigorous PA (MVPA) was associated with cardio-metabolic risk after adjustment for age, maternal education and MVPA. In contrast, TV viewing was not associated with the presence of cardio-metabolic risk. CONCLUSION In boys, playing with videogames may impair cardio-metabolic health during the adolescence. Adolescents should be encouraged to increase their participation in physical activity of at least moderate intensity to obtain a more favourable risk factor profile.

Abstract
Background Sepsis-associated brain dysfunction has been linked to white matter lesions (leukoencephalopathy) and ischemic stroke. Our objective was to assess the prevalence of brain lesions in septic shock patients requiring magnetic resonance imaging (MRI) for an acute neurologic change. Method Seventy-one septic shock patients were included in a prospective observational study. Patients underwent daily neurological examination. Brain MRI was obtained in patients who developed focal neurological deficit, seizure, coma, or delirium. Electroencephalogy was performed in case of coma, delirium, or seizure. Leukoencephalopathy was graded and considered present when white matter lesions were either confluent or diffuse. Patient outcome was evaluated at 6 months with the Glasgow Outcome Scale (GOS). Results We included 71 patients with median age of 65 years (56 to 76) and SAPS II at admission of 49 (38 to 60). MRI was indicated on focal neurological sign in 13 (18%), seizure in 7 (10%), coma in 33 (46%), and delirium in 35 (49%). MRI was normal in 37 patients (52%) and showed cerebral infarcts in 21 (29%), leukoencephalopathy in 15 (21%), and mixed lesions in 6 (8%). EEG malignant pattern was more frequent in patients with ischemic stroke or leukoencephalopathy. Ischemic stroke was independently associated with disseminated intravascular coagulation (DIC), focal neurologic signs, increased mortality, and worse GOS at 6 months. Conclusions Brain MRI in septic shock patients who developed acute brain dysfunction can reveal leukoencephalopathy and ischemic stroke, which is associated with DIC and increased mortality.

Abstract
The aim of this study is to describe the incidence of brain injury (BI) in children with end-stage cardiac failure who were supported with the Berlin Heart EXCOR ventricular assist device (VAD) as a bridge to heart transplantation. Between January 2002 and January 2012, all patients <18 years of age who underwent the implantation of the Berlin Heart EXCOR at Bambino Gesú Children's Hospital were included. A total of 25 patients were included in this study. Median age and weight at implantation were 22.4 months (range 3.6-154.2) and 10 kg (range 4.5-36), respectively. Diagnosis included cardiomyopathy (n = 20) and congenital heart disease (n = 5). Eleven patients received atrial cannulation. Nine patients underwent biventricular assist device support. Seven patients underwent extracorporeal membrane oxygenation before the implantation of the EXCOR VAD. Median duration of VAD support was 51 days (range 2-167). Nine patients had evidence of acute BI including intracranial hemorrhage (n = 5) and cerebral ischemia (n = 4). Freedom from BI at 30, 60, and 90 days from VAD implantation was 80.7, 69.9, and 43.3%, respectively. Weight <10 kg at implantation was significantly associated with BI. BI is a frequent complication among children supported with EXCOR VAD and is associated with lower weight at implantation. However, our data do not support the association between size and BI. Future prospective multicenter studies are warranted to further help understand the etiology and the impact of BI and to improve functional outcomes for children undergoing EXCOR VAD mechanical support.

Abstract
OBJECTIVES To analyse the factors associated with in-hospital mortality and mid-term significant neoaortic valve regurgitation (AR) after truncal valve (TV) repair. METHODS Eleven children underwent TV repair at our institution from July 1999 to March 2012. All children presented significant preoperative TV regurgitation. Valve anatomy was quadricuspid in 7 (64%) patients and tricuspid in 4 (36%). The median age and weight at surgery were 29.6 (range 0.3-173.2) months and 12 (range 2.2-49) kg, respectively. Repair included bicuspidalization through the approximation of two leaflets associated with triangular resection of the opposite one (n = 2, 18%), or either bicuspidalization or tricuspidalization of the TV through excision of one leaflet and related sinus of Valsalva (n = 9, 82%). In 3 patients, repair was associated with coronary detachment before cusp removal, followed by coronary reimplantation. RESULTS In-hospital death occurred in 2 (18%) patients. Factors associated with hospital mortality were age <1 year (P = 0.05), weight <3 kg (P = 0.02) and longer cross-clamping time (P = 0.008). Follow-up was complete for all patients [median follow-up time: 52.2 (range 132.2-2.5) months]. Mid-term significant AR occurred in 4 patients (45%, moderate in 2 and severe in 2). One with severe AR underwent successful valve replacement 4 months postoperatively, leading to freedom from reintervention of 91%. Freedom from significant AR was 76.2 (33.2-93.5) and 60.9 (20.2-85.6) at 1 and 2 years, respectively. There was a trend towards longer freedom from mid-term significant AR for patients who underwent cusp removal compared with those who did not (P = 0.07). CONCLUSIONS TV repair in children can be performed safely with fairly good and durable results. Cusp removal might decrease the rate of severe AR on mid-term follow-up.

Abstract
OBJECTIVE Neonates with critical congenital heart disease remain at risk of adverse outcomes after cardiac surgery. Residual or undiagnosed anatomic lesions might be contributory. The present study aimed to describe the incidence and type of cardiac lesions that lead to early, unplanned cardiac reintervention, identify the risk factors for unplanned reintervention, and explore the associations between unplanned reinterventions and hospital mortality. METHODS The present single-center retrospective cohort study included 943 consecutive neonates with critical congenital heart disease who underwent cardiac surgery from 2002 to 2008. An unplanned cardiac reintervention was defined as a cardiac reoperation or interventional cardiac catheterization performed during the same hospitalization as the initial operation. Multivariate logistic regression analyses were used to identify the risk factors for unplanned cardiac reintervention and hospital mortality. RESULTS Of the 943 neonates, 104 (11%) underwent an unplanned cardiac reintervention. The independent predictors of unplanned reintervention included prenatal diagnosis, lower birth weight, need for mechanical ventilation before the initial cardiac operation, lower attending surgeon experience, and greater Risk Adjustment in Congenital Heart Surgery, version 1, category. Those who underwent reintervention had increased hospital mortality (n = 33/104, 32%) relative to those who did not (n = 31/839, 4%; adjusted odds ratio, 8.6; 95% confidence interval, 4.7 to 15.6; P < .001). The mortality rates among patients undergoing surgical reintervention (23/66, 35%) or transcatheter reintervention (4/16, 25%), or both (6/22, 27%) were similar (P = .66). CONCLUSIONS The need for unplanned cardiac reintervention in neonates with critical congenital heart disease is strongly associated with increased mortality. Early unplanned reinterventions might be an important covariate in outcomes studies and useful as a quality improvement measure.

Abstract
Inhaled corticosteroids (ICS) are established as first-line therapy for persistent asthma in children. Fluticasone propionate (FP) has been used because it has equivalent efficacy when used at half-dose of older-generation ICS and has a comparable safety profile. However, concerns persist about the potential risk of adverse effects of long-term FP therapy on childhood growth, bone, adrenal function and immune system. To evaluate the potential adverse effects of FP, we analyzed growth, glucidic metabolism, hypothalamic-pituitary-adrenal axis, bone metabolism, bone mass density and immune system in a cohort of 19 children (average 102±18 months), with asthma who were in treatment with FP (average duration: 14 months, range: 11–17 months). Of these, 11 children homogenous for control of asthma symptoms, and compliance to therapy, were selected for a prospective study during which they were treated with FP250 mg/day for further 6 months (total period of treatment average duration: 22 months, range: 18–23 months). In all children, no alterations of growth, glucidic metabolism, hypothalamic-pituitary-adrenal axis, bone metabolism, bone mass density, immune system nor severe exacerbation of the disease were observed. Our study, showing that FP was able to control the symptoms of asthma and confirming the lack of systemic side effects at the recommended doses, supports its long-term use in children with asthma.

Abstract
We sought to describe contemporary outcomes and identify risk factors for hospital mortality in premature neonates with critical congenital heart disease who were referred for early intervention. Neonates who were born before 37 weeks' gestation with critical congenital heart disease and admitted to our institution from 2002 to 2008 were included in this retrospective cohort study. Critical congenital heart disease was defined as a defect requiring surgical or transcatheter cardiac intervention or a defect resulting in death within the first 28 days of life. Logistic regression analyses were performed to identify risk factors for mortality before hospital discharge. The study included 180 premature neonates, of whom 37 (21%) died during their initial hospitalization, including 6 (4%) before cardiac intervention and 31 (17%) after cardiac intervention. For the 174 patients undergoing cardiac intervention, independent risk factors for mortality were a 5 min Apgar score ≤ 7, need for preintervention mechanical ventilation, and Risk Adjustment in Congenital Heart Surgery category ≥ 4 or not assignable. Mortality for premature infants with critical congenital heart disease who are referred for early intervention remains high. Patients with lower Apgar scores who receive preintervention mechanical ventilation and undergo more complex procedures are at greatest risk.

Abstract
BACKGROUND Red blood cell transfusion is associated with morbidity and mortality among adults undergoing cardiac surgery. We aimed to evaluate the association of transfusion with morbidity among pediatric cardiac surgical patients. METHODS Patients discharged after cardiac surgery in 2003 were retrospectively reviewed. The red blood cell volume administered during the first 48 postoperative hours was used to classify patients into nonexposure, low exposure (≤15 mL/kg), or high exposure (>15 mL/kg) groups. Cox proportional hazards modeling was used to evaluate the association of red blood cell exposure to length of hospital stay (LOS). RESULTS Of 802 discharges, 371 patients (46.2%) required blood transfusion. Demographic differences between the transfusion exposure groups included age, weight, prematurity, and noncardiac structural abnormalities (all p<0.001). Distribution of Risk Adjusted Classification for Congenital Heart Surgery, version 1 (RACHS-1) categories, intraoperative support times, and postoperative Pediatric Risk of Mortality Score, Version III (PRISM-III) scores varied among the exposure groups (p<0.001). Median duration of mechanical ventilation (34 hours [0 to 493] versus 27 hours [0 to 621] versus 16 hours [0 to 375]), incidence of infection (21 [14%] versus 29 [13%] versus 17 [4%]), and acute kidney injury (25 [17%] versus 29 [13%] versus 34 [8%]) were highest in the high transfusion exposure group when compared with the low or nontransfusion groups (all p<0.001). In a multivariable Cox proportional hazards model, both the low transfusion group (adjusted hazard ratio [HR] 0.80, 95% confidence interval [CI]: 0.66 to 0.97, p=0.02) and high transfusion group (adjusted HR 0.66, 95% CI: 0.53 to 0.82, p<0.001) were associated with increased LOS. In subgroup analyses, both low transfusion (adjusted HR 0.81, 95% CI: 0.65 to 1.00, p=0.05) and high transfusion (adjusted HR 0.65, 95% CI: 0.49 to 0.87, p=0.004) in the biventricular group but not in the single ventricle group was associated with increased LOS. CONCLUSIONS Blood transfusion is associated with prolonged hospitalization of children after cardiac surgery, with biventricular patients at highest risk for increased LOS. Future studies are necessary to explore this association and refine transfusion practices.
