RESUMO
BACKGROUND: We aimed to assess prevalence and clinical characteristics of newborns receiving kidney replacement therapy (KRT). METHODS: We used the National Inpatient Sample (NIS) dataset for the years 2000-2017. Newborns treated with peritoneal dialysis (PD), hemodialysis (HD), and continuous KRT (CKRT) were included. Trend analysis using the Cochran-Armitage test was used to assess prevalence over the years. RESULTS: A total of 64,532,552 hospitalized newborns were included. Among the 4281 infants treated with KRT, 2501 (58.4%) were treated with PD, 997 (23.3%) had HD, and 783 (18.3%) used CKRT. Associated diagnoses included congenital kidney anomalies (37.4% vs. 15% vs. 9.5%), urinary tract anomalies (35% vs. 12.5% vs. 6.3%), and congenital heart disease (68% vs. 25.7% vs. 72.3%). Median length of stay was longest in PD patients (39 days vs. 18 days vs. 26 days), respectively. However, cost of hospitalization was greatest in CKRT patients (US $490,916 vs. US $218,514 vs. US $621,554), respectively. In the entire cohort, 54,424 newborns had acute kidney injury (AKI); of them 16,999 (31%) died. KRT was used in 2,688 (4.9%) of infants with AKI. Over the study period, trends for utilization of PD (from 0.042 to 0.06%) and CKRT (from 0.03 to 0.21%) increased whereas the hemodialysis trend decreased (from 0.021 to 0.013%). CONCLUSIONS: Congenital heart disease (CHD) and congenital anomalies of the kidneys and urinary tract (CAKUT) are the major diagnoses in newborns receiving KRT. Utilization of PD was greater than HD and CKRT. Trends of PD and CKRT utilization increased over time. Less than 5% of infants diagnosed with AKI received KRT.

Using the US National Inpatient Sample dataset (2010 to 2018), we compared outcomes of neonates with Tetralogy of Fallot who had early primary surgical repair (1726 neonate) and those who had staged palliative intervention with transcatheter (1702 neonate) or surgical palliative shunt (2661 neonate).
RESUMO
BACKGROUND: The rates, outcomes, and long-term trends of stroke complicating the use of extracorporeal membrane oxygenation (ECMO) have been inconsistently reported. We compared the outcomes of pediatric ECMO patients with and without stroke and described the frequency trends between 2000 and 2017. METHODS: Using the National Inpatient Sample (NIS) database, pediatric patients (age ≤18 years) who received ECMO were identified using ICD-9&10 codes. Binary, regression, and trend analyses were performed to compare patients with and without stroke. RESULTS: A total of 114,477,997 records were reviewed. Overall, 28,695 (0.025%) ECMO patients were identified of which 2982 (10.4%) had stroke, which were further classified as hemorrhagic (n = 1464), ischemic (n = 1280), or combined (n = 238). Mortality was higher in the hemorrhagic and combined groups compared to patients with ischemic stroke and patients without stroke. Length of stay (LOS) was significantly longer in stroke vs. no-stroke patients. Hypertension and septicemia were more encountered in the hemorrhagic group, whereas the combined group demonstrated higher frequency of cardiac arrest and seizures. CONCLUSIONS: Over the years, there is an apparent increase in the diagnosis of stroke. All types of stroke in ECMO patients are associated with increased LOS, although mortality is increased in hemorrhagic and combined stroke only. IMPACT: Stroke is a commonly seen complication in pediatric patients supported by ECMO. Understanding the trends will help in identifying modifiable risk factors that predict poor outcomes in this patient population.

BACKGROUND AND OBJECTIVES: The use of inhaled nitric oxide (iNO) in +late preterm and term infants with pulmonary hypertension is Food and Drug Administration (FDA) approved and has improved outcomes and survival. iNO use is not FDA approved for preterm infants and previous studies show no mortality benefit. The objectives were 1) to determine the usage of iNO among preterm neonates <35 weeks before and after the 2010 National Institutes of Health consensus statement and 2) to evaluate characteristics and outcomes among preterm neonates who received iNO. METHODS: This is a population-based cross-sectional study. Billing and procedure codes were used to determine iNO usage. Data were queried from the National Inpatient Sample from 2004 to 2016. Neonates were included if gestational age was <35 weeks. The epochs were spilt into 2004-2010 (Epoch 1) and 2011-2016 (Epoch 2). Prevalence of iNO use, mortality, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage, length of stay, mechanical ventilation, and cost of hospitalization. RESULTS: There were 4865 preterm neonates <35 weeks who received iNO. There was a significant increase in iNO use during Epoch 2 (p < 0.001). There was significantly higher use in Epoch 2 among neonates small for gestational age (SGA) 2.3% versus 7.2%, congenital heart disease (CHD) 11.1% versus 18.6%, and BPD 35.2% versus 46.8%. Mortality was significantly lower in Epoch 2 19.8% versus 22.7%. CONCLUSION: Usage of iNO was higher after the release of the consensus statement. The increased use of iNO among preterm neonates may be targeted at specific high-risk populations such as SGA and CHD neonates. There was lower mortality in Epoch 2; however, the cost was doubled.

BACKGROUND: Outcomes of patients with implanted left ventricular assist device (LVAD) implantation experiencing a cardiac arrest (CA) are not well reported. We aimed at defining the in-hospital outcomes of patients with implanted LVAD experiencing a CA. METHODS: The national inpatient sample (NIS) was queried using ICD9/ICD10 codes for patients older than 18 years with implanted LVAD and CA between 2010-2018. We excluded patients with orthotropic heart transplantation, biventricular assist device (BiVAD) implantation and do not resuscitate (DNR) status. RESULTS: A total of 93,153 hospitalisations between 2010 and 2018 with implanted LVAD were identified. Only 578 of these hospitalisations had experienced CA and of those, 173 (33%) hospitalisations underwent cardiopulmonary resuscitation (CPR). The mean age of hospitalisations that experienced a CA was 60.61±14.85 for non-survivors and 56.23±17.33 for survivors (p=0.14). The in-hospital mortality was 60.8% in hospitalisations with CA and 74.33% in hospitalisations in whom CPR was performed. In an analysis comparing survivors with non-survivors, non-survivors had more diabetes mellitus (DM) (p=0.01), and ischaemic heart disease (IHD) (p=0.04). Age, female sex, peripheral vascular disease and history of coronary artery bypass graft (CABG) were independently associated with increased mortality in our cohort. Also, ventricular tachycardia (VT) and CPR were independently associated with in-hospital mortality. During the study period, there was a significantly decreasing trend in performing CPR in LVAD hospitalisations with CA. CONCLUSION: In conclusion, age, female sex, peripheral vascular disease, history of CABG, VT and CPR were independently associated with in-hospital mortality in LVAD hospitalisations who experienced CA.

OBJECTIVE: The use of supplemental oxygen in premature infants is essential for survival. However, its use has been associated with unintended complications. The restricted use of oxygen is associated with increased mortality and necrotizing enterocolitis (NEC), whereas its liberal use is associated with increased risk for retinopathy of prematurity (ROP). Although there is no clear consensus on the acceptable oxygen saturation range, clinicians have recently become more liberal with the use of oxygen. We aim to assess (1) the national trends for ROP in very low birth weight preterm infants, and (2) the associated trends in mortality, NEC, intraventricular hemorrhage (IVH), and length of hospital stay (LOS). STUDY DESIGN: We analyzed deidentified patient data from the National Inpatient Sample (NIS) of the Healthcare Cost and Utilization Project (HCUP) from 2002 to 2017. All infants with gestational age ≤32 weeks and birth weight <1,500 g were included. Trends in ROP, severe ROP, mortality, NEC, IVH, severe IVH, and LOS were analyzed using Jonckheere-Terpstra test. RESULTS: A total of 818,945 neonates were included in the study. The overall mortality was 16.2% and the prevalence of ROP was 17.5%. There was a significant trend for increased ROP over the years (p < 0.001). Severe ROP was also significantly increased (p < 0.001). This was associated with a significant trend for increased median LOS in survived infants (p < 0.001). Mortality was significantly decreased (p < 0.001), whereas NEC and severe NEC did not change over time (p = 0.222 and p = 0.412, respectively). CONCLUSION: There is a national trend for increased ROP and severe ROP over the 16 years of the study period. This trend was associated with a significant increase in the LOS in survived infants without change in NEC. KEY POINTS: · Prevalence of ROP and severe ROP has increased in VLBW infants over the 16-year study period.. · The prevalence of NEC did not change over the same time period.. · Increased ROP and severe ROP were consistent in all three GA and BW subgroups..

BACKGROUND: Prophylactic platelet transfusion has been adopted as a ubiquitous practice in management of thrombocytopenia in preterm infants to reduce the risk of bleeding. OBJECTIVES: The objectives of this study were to report the prevalence of platelet transfusion among preterm infants with thrombocytopenia and to assess the association of platelet transfusion with mortality and morbidity in this population. METHODS: A cross-sectional study that utilized National Inpatient Sample for the years 2000-2017 was conducted. All preterm infants delivered nationally with birth weight (BW) <1,500 g or gestational age <32 weeks were included. Analyses were repeated after stratifying the population into 2 BW subcategories <1,000 g and 1,000-1,499 g. Logistic regression analysis was performed to adjust for confounding variables. RESULTS: The study included 1,780,299 infants; of them, 22,609 (1.27%) were diagnosed with thrombocytopenia and 5,134 (22.7%) received platelet transfusion. Platelet transfusion was associated with significant increase in mortality (24.8 vs. 13.8%), retinopathy of prematurity (22.3 vs. 19.2%), severe intraventricular hemorrhage (18.3 vs. 10.1%), median length of hospital stays (51 vs. 47 days), and cost of hospitalization (USD 298,204 vs. USD 219,760). Increased mortality was noted in <1,000-g infants (aOR = 1.96, CI: 1.76-2.18, p < 0.001) and 1,000-1,499-g infants (aOR = 2.02, CI: 1.62-2.53, p < 0.001). Platelet transfusion increased over the years in infants with BW <1,000 g (p = 0.001) and in infants with BW 1,000-1,499 g (p < 0.001). CONCLUSIONS: Platelet transfusion is associated with increased mortality and comorbidities in premature infants. There is a trend for increased utilization of platelet transfusions over the study period.

We report on in-hospital cardiac arrest outcomes in the USA. The data were obtained from the National (Nationwide) Inpatient Sample datasets for the years 2000-2017, which includes data from participating hospitals in 47 US states and the District of Columbia. We included pediatric patients (< 18 years of age) with cardiac arrest, and we excluded patients with no cardiopulmonary resuscitation during the hospitalization. Primary outcome of the study was in-hospital mortality after cardiac arrest. A multivariable logistic regression was performed to identify factors associated with survival. A total of 20,654 patients were identified, and 8226 (39.82%) patients survived to discharge. The median length of stay and cost of hospitalization were significantly higher in the survivors vs. non-survivors (LOS 18 days vs. 1 day, and cost $187,434 vs. $45,811, respectively, p < 0.001). In a multivariable model, patients admitted to teaching hospitals, elective admissions, and those admitted on weekdays had higher survival (aOR=1.19, CI: 1.06-1.33; aOR=2.65, CI: 2.37-2.97; and aOR=1.17, CI: 1.07-1.27, respectively). There was no difference in mortality between patients with extracorporeal cardiopulmonary resuscitation (E-CPR) and those with conventional cardiopulmonary resuscitation. E-CPR patients were likely to have congenital heart surgery (51.0% vs. 20.8%).Conclusion: We highlighted the survival predictors in these events, which can guide future studies aimed at improving outcomes in pediatric cardiac arrest. What is Known: ⢠In-hospital cardiac arrest occurs in 2-6% of pediatric intensive care admissions. ⢠Cardiac arrests had a significant impact on hospital resources and a significantly high mortality rate. What is New: ⢠Factors associated with higher survival rates in patients with cardiac arrest: admission to teaching hospitals, elective admissions, and week-day admissions. ⢠The use of rescue extracorporeal cardiopulmonary resuscitation in refractory cardiac arrest has increased by threefold over the last two decades.

BACKGROUND: The prevalence, morbidity, and mortality associated with Ebstein anomaly (EA) remains poorly characterized in neonates. EA is a rare form of congenital heart disease (CHD) with significant heterogeneity. OBJECTIVE: To determine the recent, 2000-2018, prevalence, mortality, outcomes, and healthcare utilization of infants admitted at ≤28 days of life with EA in comparison to other critical congenital heart defects (CCHD) in the United States using a national data set. METHODS: The National Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project (HCUP) was queried for infants admitted for any reason at ≤28 days of life with a diagnosis of EA between 2000 and 2018 using ICD-9 and 10 codes in the United States. Patient characteristics, morbidity, mortality, and healthcare utilization were evaluated for EA and compared with other CCHD. RESULTS: From 2000 to 2018 a total of 68,312,952 neonatal admissions were identified, of them 4,398 neonates with isolated EA were identified, representing 7 per 100,000 neonatal admissions and 2.2% of CCHD admissions (4,398/197,881). The number of new EA cases ranged from 138 to 375 per year. In-hospital mortality was 12.3% and surgical repair occurred in 4.2% for infants with EA. There were 470 deaths without surgical repair which is 86.6% of the mortality. Arrhythmias were diagnosed in 10.6% and ECMO was used for 2.6% of neonates with EA. CONCLUSION: EA is a rare form of CHD. The prevalence has remained stable over the 19 years whereas other congenital heart defects have had an increase. The mortality in neonates with EA was significantly higher than in pooled CCHD; the burden of mortality occurred in the neonates without surgical intervention.

OBJECTIVES: To assess the prevalence and outcomes of spontaneous intestinal perforation (SIP) in very low birth weight infants. STUDY DESIGN: This cross-sectional study utilized the National Inpatient Sample dataset for the years 2002-2017. All premature infants with birth weight (BW) <1500 g and with gestational age (GA) ≤32 weeks were included. Analyses were repeated after stratifying the population into two BW sub-categories <1000 g and 1000-1499 g. Trend analysis was done using Cochran-Armitage test. Regression analysis was conducted to control for gestational age, race, and sex. RESULT: A total of 658,001 infants were included. SIP (n = 10,443, 1.6%) was mostly (81.9%) in the category <1000 g with 89.9% ≤28 weeks of gestation. There was a significant trend for increased SIP over the years (p < 0.001). SIP was associated with increased mortality (aOR = 2.24, CI: 2.04-2.46, p < 0.001). CONCLUSION: After controlling for gestational age and other confounders, SIP is associated with increased mortality in premature infants.

BACKGROUND: To assess prevalence and outcomes of acute kidney injury (AKI) in very-low-birth-weight infants. METHODS: This cross-sectional study utilized the National Inpatient Sample (NIS) dataset for years 2000-2017. All premature infants with birth weight (BW) <1500g and/or gestational age (GA) ≤32 weeks were included. Analyses were conducted for overall population and two BW categories: <1000g and 1000-1499g. Adjusted odds ratios were calculated after controlling for confounding variables in logistic regression analysis. Cochrane-Armitage test was used to assess for statistically significant trends in AKI frequency over the years. RESULTS: In total, 1,311,681 hospitalized premature infants were included; 19,603 (1.5%) were diagnosed with AKI. The majority (74.3%) were BW <1000g and 63.9% ≤28 weeks gestation. Prevalence of AKI differed by ethnicity; White had significantly less AKI than Black (OR=0.79, p<0.001) and Hispanic (OR=0.83, p<0.001). AKI was significantly associated with higher mortality compared to controls (35.1 vs. 3.0%, p<0.001). AKI was associated with comorbidities such as necrotizing enterocolitis, patent ductus arteriosus, bronchopulmonary dysplasia, intraventricular hemorrhage, and septicemia. In a regression model, AKI was associated with higher mortality after controlling confounding factors (aOR=7.79, p<0.001). AKI was associated with significant increase in length of stay (p<0.001) and cost of hospitalization in survivors (p<0.001). There is a significant trend for increased AKI frequency over the years (Z score=4.33, p<0.001). CONCLUSION: AKI is associated with increased mortality and comorbidities in preterm infants, especially in infants with BW <1000g. Further studies are needed to understand precipitating factors and assess preventative measures for this serious complication.

OBJECTIVE: The objective of this study was to identify patient and hospitalization characteristics associated with in-hospital mortality in infants with truncus arteriosus. METHODS: We conducted a retrospective analysis of a large administrative database, the National Inpatient Sample data set of the Healthcare Cost and Utilization Project for the years 2002 to 2017. We also sought to evaluate the resource utilization in the subgroup of subjects with truncus arteriosus and 22q11.2 deletion syndrome. Neonates with truncus arteriosus were identified by ICD-9 and ICD-10 codes. Hospital and patient factors associated with inpatient mortality were analyzed. RESULTS: Overall, 3009 neonates met inclusion criteria; a total of 326 patients died during the hospitalization (10.8%). Extracorporeal membrane oxygenation utilization was 7.1%. Univariate and multivariate logistic regression analyses were used to identify risk factors for in-hospital mortality. Significant risk factors for mortality were prematurity (adjusted odds ratio [aOR] = 2.43; 95% confidence interval [CI]: 1.40-4.22; P = .002), diagnosis of stroke (aOR = 26.2; 95% CI: 10.1-68.1; P < .001), necrotizing enterocolitis (aOR = 3.10; 95% CI: 1.24-7.74; P = .015) and presence of venous thrombosis (aOR = 13.5; 95% CI: 6.7-27.2; P < .001). Patients who received extracorporeal membrane oxygenation support or had cardiac catheterization procedure during the hospitalization had increased odds of mortality (aOR = 82.0; 95% CI: 44.5-151.4; P < .001, and aOR = 1.65; 95% CI: 0.98-2.77; P = .060, respectively). CONCLUSION: 22q11.2 deletion syndrome was associated with an inverse risk of death despite having more noncardiac comorbidities; this patient subpopulation also had a higher length of stay and increased cost of hospitalization.

Children affected with acute myocarditis may progress rapidly into profound ventricular dysfunction and ventricular arrhythmias. The objective of this study is to assess the impact of ventricular arrhythmias on in-hospital mortality and the use of mechanical circulatory support in patients with myocarditis. Pediatric patients (age 0-18 years) admitted with myocarditis were identified from the National Inpatient Sample dataset for the years 2002-2015. A total of 12,489 patients with myocarditis were identified. Of them, 1627 patients were with ventricular arrhythmias and 10,862 patients without ventricular arrhythmias. Mortality was higher in those with ventricular arrhythmias (19.5% vs. 2.8%, OR = 8.47; 95% CI 7.16-10.04; p < 0.001). The median length of stay and the median cost of hospitalization were higher in the ventricular arrhythmias group (9 days vs. 4 days, p < 0.001 and $121,826 vs. $37,658, p < 0.001, respectively). There was a substantial increase in the utilization of extracorporeal membrane oxygenation (ECMO) in patients with ventricular arrhythmias (25.4% vs. 2.7%, OR = 12.40; 95% CI 10.55-14.57; p < 0.001). The use of ventricular assist devices (VADs) was higher in patients with ventricular arrhythmias (4.5% vs. 1.3%, OR = 3.76; 95% CI 2.82-5.01; p < 0.001). An improvement in discharge survival was observed over the years of study in both VA and non-VA groups; associated with this decline in mortality, there was a rising trend of ECMO utilization.Conclusion: Development of ventricular arrhythmia in children with myocarditis is a strong predictor for mortality and ECMO utilization. What is Known: ⢠The clinical presentation of pediatric myocarditis varies from no symptoms of myocardial dysfunction to a rapidly progressing severe congestive heart failure. ⢠Little is known about the predictors of mortality in children with suspected myocarditis. What is New: ⢠Development of ventricular arrhythmia in children with myocarditis is a strong predictor for mortality and ECMO utilization. ⢠Improvement in discharge survival was observed over the years of study; associated with this decline in mortality, there was a rising trend of ECMO utilization.

BACKGROUND: Patent ductus arteriosus (PDA) is frequently encountered in premature infants. Optimal management of PDA remains undefined. We aim to assess the national trend for PDA ligation over 18 years and evaluate mortality and associated morbidities. METHODS: We used data from the National Inpatient Sample (NIS) and KID of the Healthcare Cost and Utilization Project (HCUP) from 1998 to 2015. All infants with gestational age 24-32 weeks and birth weight <1500 g were included. Patients with PDA were classified into two groups: those who did and did not receive surgical ligation. Associated mortality and morbidities were compared. RESULTS: A total of 429,900 neonatal admissions were identified. Of them, 149,473 (34.8%) infants had PDA. PDA-ligated infants were 27,364 (6.4%). PDA ligation was more likely in those with smaller gestational age and with birth weight <1000 g. A steady decline in PDA ligation was noticed since 2004. The mortality rate in PDA-ligated infants was less than in PDA-non-ligated infants (7.5% vs. 8.9%; OR = 0.82; 95% CI: 0.78-0.86; p < 0.001). However, the prevalence rates of pulmonary hemorrhage and necrotizing enterocolitis (NEC) were greater in PDA-ligated infants (OR = 1.58; 95% CI: 1.49-1.67; p < 0.001, and OR = 1.32; 95% CI: 1.26-1.38; p < 0.001, respectively). CONCLUSIONS: Ligation of PDA has been steadily declining since 2004. Despite higher morbidities, PDA-ligated infants had less mortality.

The objective of this study was to identify patient and hospitalization characteristics associated with in-hospital mortality in infants with hypoplastic left heart syndrome (HLHS). We conducted a retrospective analysis of a large administrative database, the National Inpatient Sample dataset of the Healthcare Cost and Utilization Project for the years 2002-2016. Neonates with HLHS were identified by ICD-9 and ICD-10 codes. Hospital and patient factors associated with inpatient mortality were analyzed. Overall, 18,867 neonates met the criteria of inclusion; a total of 3813 patients died during the hospitalization (20.2%). In-hospital mortality decreased over the years of the study (27.0% in 2002 vs. 18.3% in 2016). Extracorporeal membrane oxygenation utilization was 8.1%. Univariate and multivariate logistic regression analyses were used to identify risk factors for in-hospital mortality in infants with hypoplastic left heart syndrome. Independent non-modifiable risk factors for mortality were birth weight < 2500 g (Adjusted odds ratio (aOR) 2.16 [1.74-2.69]), gestational age < 37 weeks (aOR 1.73 [1.42-2.10]), chromosomal abnormalities (aOR 3.07 [2.60-3.64]) and renal anomalies (aOR 1.34 [1.10-1.61]). Independent modifiable risk factors for mortality were being transferred-in from another hospital (aOR 1.15 [1.03-1.29]), use of extracorporeal membrane oxygenation (aOR 12.74 [10.91-14.88]). Receiving care in a teaching hospital is a modifiable variable, and it decreased the odds of mortality (aOR 0. 78 [0.64-0.95]). In conclusion, chromosomal anomalies, Extra Corporeal Membrane Oxygenation, gestational age < 37 weeks or birth weight < 2500 g were associated with increased odds of mortality. Modifiable variables as receiving care at birth center and in a hospital designated as a teaching hospital decreased the odds of mortality.

OBJECTIVE: The objective of this study was to use current national data to evaluate the characteristics and survival trends of preterm infants born with CDH from 2004 to 2014. STUDY DESIGN: Data was queried from the National Inpatient Sample (NIS) and KID database from 2004 to 2014. Infants were included if diagnosed with CDH by ICD-9 coding and gestational age <37 weeks. Descriptive statistics, chi-square, and trend analysis were completed. RESULTS: We identified 2356 infants born prematurely with CDH. The overall survival rate was 49%. The survival range is 21.2-62.3% for gestational age <26 weeks to 35-36 weeks, respectively. Total mortality was 1183; of them, 1052 (89%) were not repaired and 363 (30.7%) did not receive mechanical ventilation. Surgical repair occurred in 55.1% of infants. CONCLUSIONS: Preterm infants have lower survival compared with term infants. Survival rates decrease with lower gestational age and have improved over time.

Neonates with hypoplastic left heart syndrome (HLHS) were identified from the National Inpatient Sample dataset for the years 1998-2014. These patients were stratified into two chronological groups, past group (1998-2005) and recent group (2006-2014). A total of 20,649 neonates with HLHS were identified. Of them, 9179 (44.5%) were born in the past group and 11,470 (55.5%) in the recent group. Median birth weight was significantly less in the recent group (2967 g vs. 3110 g, p = 0.005). The patients in the recent group had more patients with low birth weight ( < 2.5 kg) and prematurity (8.7% vs 7.6% and 12.7% vs. 4.3%., respectively). In addition, recent group had more comorbidities including chromosomal anomalies, total anomalous pulmonary venous return, and kidney anomalies (5.6% vs. 3.6%, 2.3% vs. 1.7%, and 5.6% vs. 3.6%, respectively, p < 0.001); these were associated with a higher rate of extracorporeal membrane oxygenation utilization (9.2% vs. 4.5%, p < 0.001). Consequently, median length of stay was longer in the recent group (8 vs. 6 days, p < 0.001).Conclusion: Despite the higher frequency of comorbidities in recent group, the mortality rates decreased by 20% (from 25.3% to 20.6%, p < 0.001). Balloon atrial septostomy was performed less frequently in the recent group (23.3% vs. 16.1%, p < 0.001).What is known:⢠Hypoplastic left heart syndrome has the highest mortality among congenital cardiac defects during the first year of life.⢠Limited studies on patients' comorbidities and mortality rates trends over last two decades.What is new:⢠The study utilized a national database to compare in-hospital mortality and length of stay between the two time periods 1998-2005 and 2006-2014.⢠The recent group had more comorbidities (prematurity, chromosomal anomalies, total anomalous pulmonary venous return, and kidney anomalies), and there was higher rate of ECMO and longer length of stay, while mortality rates decreased by 20%.

OBJECTIVES: Transposition of the great arteries is the most common cyanotic congenital heart defect. Surgical correction usually occurs in the first week of life; presence of restrictive interatrial communication and severe hypoxemia warrants urgent intervention with balloon atrial septostomy and medical stabilization prior to surgery. The main objective of this study is to compare the characteristics, outcomes, and mortality risks in patients with transposition of the great arteries who underwent balloon atrial septostomy during their hospitalization versus transposition of the great arteries patients who have not undergone this procedure. DESIGN: Retrospective analysis of administrative data. SETTING: Data from Kids' Inpatient Database complemented with the National Inpatient Sample dataset for the years 1998-2014, this includes data from participating hospitals in 47 U.S. States and the District of Columbia. PATIENTS: Neonates admitted with transposition of the great arteries. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 17,392 neonates with diagnosis of transposition of the great arteries were captured in the databases we used. Male-to-female ratio was 2:1. The rate of balloon atrial septostomy in patients with transposition of the great arteries was 27.7% without significant change over the years. There was no significant difference in mortality between balloon atrial septostomy and no balloon atrial septostomy (6.3% vs 6.7%; p = 0.29). Neonates with balloon atrial septostomy had a two-fold increase in their length of stay compared with no balloon atrial septostomy (16 d vs 7 d; p < 0.0001). Stroke was present in 1.1% of balloon atrial septostomy group versus 0.6% in those who did not have balloon atrial septostomy (odds ratio, 1.85; 95% CI, 1.29-2.65; p < 0.0001). Extracorporeal membrane oxygenation was used more in balloon atrial septostomy group (5.1% vs 3.1%; p < 0.0001). CONCLUSIONS: There was no difference in mortality rate between balloon atrial septostomy and no balloon atrial septostomy patients. The prevalence of the diagnosis of stroke in this study was higher in patients who underwent balloon atrial septostomy. Furthermore, comparison of in-hospital mortality in balloon atrial septostomy and no balloon atrial septostomy revealed increased mortality risk in no balloon atrial septostomy patients transferred from other institution, no balloon atrial septostomy patients supported with extracorporeal membrane oxygenation, and balloon atrial septostomy patients diagnosed with stroke. Finally, length of stay and charges were higher in balloon atrial septostomy patients.

An antimicrobial agent, benzalkonium chloride (BAC), was added to a chemically cured composite resin, and the antimicrobial benefits and physical properties of the modified composite were evaluated. BAC was added to Reliance Phase II composite to create modified composites with BAC concentrations ranging from 0.25 to 2.50 wt%. Specimen disks of the modified composite were incubated with Streptococcus mutans for 48 hours, and an agar disk diffusion assay was used to measure zones of bacterial inhibition. Larger disks were suspended in brain-heart infusion medium containing 2 x 10(4) colony-forming units/mL Streptococcus sobrinus (10 mL, 2 wt% sucrose, 24 hours) to measure bacterial adherence to the adhesive; adherent cells were removed from the surface with 1 N NaOH, and the optical density of the cells was measured at 550 nanometers. Traction hooks were bonded to bovine teeth with the modified composite, and tensile bond strength was evaluated with a universal testing machine. Diametral tensile stress was also measured. The modified composite samples showed that antimicrobial activity increased with higher BAC content; no antimicrobial activity was measured for the original compound in either the disk diffusion or the bacterial adherence test. There were no significant differences (P <.05) in either tensile bond strength or diametral tensile stress among the modified composite groups and the original product. The incorporation of BAC in composite material added antimicrobial properties to the original compound without altering its mechanical properties.
