Abstract
OBJECTIVES Our objective was to investigate the prevalence of small intestinal atresia and Hirschsprung's disease (HD) in infants with Down syndrome (DS) and its impact on outcomes. STUDY DESIGN We analyzed the National Inpatient Sample dataset. We included infants with DS, small intestinal atresia, HD, and the concomitant occurrence of both conditions. Regression analysis was used to control clinical and demographic variables. RESULTS A total of 66,213,034 infants were included, of whom, 99,861 (0.15%) had DS. The concomitant occurrence of small intestinal atresia and HD was more frequent in infants with DS compared with the general population, adjusted odds ratio (aOR): 122, 95% confidence interval (CI): 96-154, (p < 0.001). Infants with DS and concomitant small intestinal atresia and HD had higher mortality compared with those without these conditions, aOR: 8.59, 95% CI: 1.95-37.8. CONCLUSION Infants with DS are at increased risk of concomitant small intestinal atresia and HD, and this condition is associated with increased mortality. KEY POINTS · Infants with Down syndrome are at increased risk of congenital GI anomalies.. · Infants with Down syndrome are at increased risk of necrotizing enterocolitis.. · Increased mortality in Down syndrome infants with concomitant small intestinal atresia and Hirschsprung's disease..

Abstract
OBJECTIVE We characterize the most recent natural history of necrotizing enterocolitis (NEC), as this is an essential first step in guiding the prevention and treatment of this disease in the present day. STUDY DESIGN We performed a retrospective cohort study of neonates who were born at 23 to 29 weeks' gestation and birth weight <1,500 g who received care from the Pediatrix Medical Group between 2004 and 2019. We assessed the incidence of medical and surgical NEC and the patterns of initial antibiotic treatment to develop a contemporary cohort for further analysis. Among patients discharged between 2015 and 2019, we characterized the stage-specific risk factors for patients diagnosed with medical or surgical NEC, as well as patterns of disease onset, progression, biomarkers, and outcomes. We used the same approach to characterize patients diagnosed with suspected NEC. RESULTS Among 34,032 patients in the contemporary cohort, 1,150 (3.4%) were diagnosed with medical NEC and 543 (1.6%) were diagnosed with surgical NEC. The temporal pattern of disease onset was different for medical and surgical NEC, with gestational age- and birth weight-specific risk disparities emerging earlier in surgical NEC. Thirty-day mortality was much greater among surgical NEC patients (medical NEC 16.4% vs. surgical NEC 43.0%), as were rates of various in-hospital and long-term outcomes. Suspected NEC was diagnosed in 1,256 (3.7%) patients, among whom risk factors and disease onset, progression, and outcomes closely resembled those of medical NEC. CONCLUSION Analyzing data from a contemporary cohort enabled us to characterize the current, stage-specific natural history of NEC, including novel insights into suspected NEC. Future studies could leverage this cohort to characterize how specific patient characteristics, care processes, or biomarkers may influence or predict disease outcomes. KEY POINTS · The incidence of NEC has reached a stable baseline in recent years.. · Risk factors for NEC vary in a stage-specific manner.. · The stage-specific onset and progression of NEC differ by gestational age and birth weight..

[PMID: 37898703 DOI: 10.1038/s41390-023-02870-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 09/16/2023] [Accepted: 10/12/2023] [Indexed: 10/30/2023]
Abstract
BACKGROUND We often encounter preterm infants with Down syndrome (DS) who die in the neonatal intensive care unit (NICU). In this study, we examined survival until NICU discharge and assessed the developmental prognosis of preterm infants with DS. METHODS We retrospectively reviewed 416 infants with DS hospitalized during the past 27 years at our NICU. RESULTS Death occurred in 8/20 (40%) infants at <32 weeks' gestation, 11/23 (48%) at 32-33 weeks, 9/99 (9%) at 34-36 weeks, and 9/274 (3%) at >36 weeks. In total, 84% of infants who died and 25% of those who survived had a non-reassuring fetal status (p < 0.001). Sex, small-for-gestational-age status, and postnatal transport were not associated with death. The main causes of death were bronchopulmonary dysplasia in 4/8 (50%) infants at <32 weeks' gestation, transient abnormal myelopoiesis in 11/20 (55%) and lymphatic dysplasia in 6/20 (30%) at 32-36 weeks, and varied causes at >36 weeks. Among survivors born at <34 weeks' gestation, 6/19 (32%) aged >2 years had moderate or severe cerebral palsy. CONCLUSIONS These data on the high mortality and morbidity of preterm infants with DS may be useful for patient treatment and parent counseling in NICUs treating critically ill infants. IMPACT Most infants with Down syndrome born at <34 weeks' gestation are born by cesarean section because of the non-reassuring fetal status. The mortality rate before discharge for infants with Down syndrome born at <34 weeks' gestation was 40%, and 30% of survivors developed moderate or severe cerebral palsy. The risk of death due to bronchopulmonary dysplasia and pulmonary hypertension was high in very preterm infants with Down syndrome despite the absence of chorioamnionitis. Infants with Down syndrome were born 1-2 weeks earlier than unaffected controls.

Abstract
AIM This study aimed to clarify the characteristics and their mortality-related factors in very low birthweight infants with Down syndrome (DS) in Japan. METHODS This retrospective case-control study enrolled newborns with DS weighing <1500 g admitted to neonatal intensive care unit (NICU) of the perinatal centre registered with the Neonatal Research Network of Japan (NRNJ) database from 2008 to 2019. The clinical characteristics and their mortality-related factors were compared among the Dead group (newborns with DS who died in the NICU), the Survival group (newborns with DS who were alive from the NICU) and the Control group (newborns without congenital or chromosomal condition). RESULTS A total of 53 656 newborns weighing <1500 g were registered in the NRNJ database for 12 years. Of these, 310 (0.6%) were diagnosed with DS: 62 newborns in the Dead group, 248 in the Survival group and 49 786 in the Control group without chromosomal condition. Logistic analysis revealed that there was a significant difference in the mortality-related factors in congenital anomalies, pulmonary haemorrhage and persistent pulmonary hypertension of the newborn; the adjusted odds ratios were 8.6, 121 and 9.5, respectively. Newborns with DS weighing <1000 g showed the earliest death in the NICU on the Kaplan-Meier survival curve (P < 0.01). CONCLUSION The mortality rate for newborns with DS weighing <1500 g was 20% (5% in the Control group). The mortality-related factors were complications of congenital anomalies, pulmonary haemorrhage and persistent pulmonary hypertension of the newborn.

Abstract
Neonates with congenital heart disease (CHD) are at an increased risk of developing necrotizing enterocolitis (NEC), an acute inflammatory intestinal injury most commonly associated with preterm infants. The rarity of this complex disease, termed cardiac NEC, has resulted in a dearth of information on its pathophysiology. However, a higher incidence in term infants, effects on more distal regions of the intestine, and potentially a differential immune response may distinguish cardiac NEC as a distinct condition from the more common preterm, classical NEC. In this review, risk factors, differentiated from those of classical NEC, are discussed according to their potential contribution to the disease process, and a general pathogenesis is postulated for cardiac NEC. Additionally, biomarkers specific to cardiac NEC, clinical outcomes, and strategies for achieving enteral feeds are discussed. Working towards an understanding of the mechanisms underlying cardiac NEC may aid in future diagnosis of the condition and provide potential therapeutic targets.

Mortality and morbidity of infants with trisomy 21, weighing 1500 grams or less, in Japan. J Hum Genet 2022; 67:623-628. [PMID: 35787654 DOI: 10.1038/s10038-022-01061-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 05/26/2022] [Accepted: 06/22/2022] [Indexed: 11/09/2022]
Abstract
Although very low birth weight (VLBW) is well studied in neonatology and the perinatal prognosis of VLBW infants has improved over time, little is known about the prognosis of VLBW infants with trisomy 21 (T21). We aimed to investigate the mortality and morbidity of VLBW infants with T21 during NICU admission in Japan, in comparison to those of infants without birth defects (BD-). Maternal and neonatal data of infants weighing 1500 grams or less admitted to the centers of the Neonatal Research Network of Japan from 2003 to 2016 were collected prospectively. Of 60,136 infants, 328 (0.55%) had T21. Although maternal age in the case of T21 infants was higher, maternal complications tended to be less frequent than in those with BD-. Multivariable analysis revealed that morbidities were higher in infants with T21 than in those with BD- but respiratory distress syndrome and retinopathy of prematurity were less frequent in those with T21 (p < 0.001, and p = 0.014, respectively), and no significant difference was observed between the two groups in the proportion of late-onset circulatory collapse of prematurity as well as cystic periventricular leukomalacia (p = 0.739 and p = 0.733, respectively). The survival rate at discharge from the NICU was 77% and 94% for T21 and BD-, respectively. This was the first nationwide survey of VLBW infants with T21 in Japan. Although there were no data regarding the timing of diagnosis, these data will aid prenatal genetic counseling and perinatal management of T21 infants.

Abstract
OBJECTIVE Newborns with trisomy 21 (T21) often require NICU hospitalization. Oxygen desaturations are frequently observed in these infants, even in the absence of congenital heart defects (CHD). We hypothesized that NICU patients with T21 have more hypoxemia than those without T21. DESIGN All infants with T21 without significant CHD discharged home from the NICU between 2009 and 2018 were included (n = 23). Controls were matched 20:1 for gestational age and length of stay. We compared daily severe hypoxemia events (SpO2 < 80% for ≥10 s) for the whole NICU stay and the pre-discharge week. RESULTS Infants with T21 showed significantly more daily hypoxemia events during their entire NICU stay (median 10 versus 7, p = 0.0064), and more so in their final week (13 versus 7, p = 0.0008). CONCLUSION NICU patients with T21 without CHD experience more severe hypoxemia events than controls, particularly in the week before discharge. Whether this hypoxemia predicts or contributes to adverse outcomes is unknown.

Abstract
Infants with congenital heart disease (CHD) are at an increased risk of developing necrotising enterocolitis (NEC), a serious inflammatory intestinal condition classically associated with prematurity. CHD not only increases the risk of NEC in preterm infants but is one of the most commonly implicated risk factors in term infants. Existing knowledge on the topic is limited largely to retrospective studies. This review acts to consolidate existing knowledge on the topic in terms of disease incidence, pathophysiology, risk factors, outcomes and the complex relationship between NEC and enteral feeds. Potential preventative strategies, novel biomarkers for NEC in this population, and the role of the intestinal microbiome are all explored. Numerous challenges exist in the study of this complex multifactorial disease which arise from the heterogeneity of the affected population and its relative scarcity. Nevertheless, its high related morbidity and mortality warrant renewed interest in identifying those infants most at risk and implementing strategies to reduce the incidence of NEC in infants with CHD.

Abstract
OBJECTIVE To evaluate the mortality and morbidity of very low birth weight (VLBW) preterm infants with birth defects in Japan. STUDY DESIGN Data were collected prospectively for infants weighing <1501 g and born at <37 weeks of gestation admitted to centers of the Neonatal Research Network of Japan during 2003-2016. We compared outcomes of infants with and without birth defects using Pearson χ2 test, Wilcoxon rank-sum test, log-rank test, nominal logistic regression analysis, and stratified analysis by birth defect subgroups. This study was approved by the Ethics Committee of Kyoto University Graduate School and Faculty of Medicine. RESULTS Among 57 730 VLBW preterm infants, 3557 infants (6.2%) were born with birth defects. Chromosomal abnormalities, congenital heart defects, and congenital malformation of the digestive system were the most common categories. Among diseases, Trisomy 18, Down syndrome, and cleft palate were the most prevalent. There were significant differences between perinatal characteristics of infants with and without birth defects. Most categories of morbidity occurred more frequently in infants with birth defects compared with those without birth defects. The aOR for mortality during the neonatal intensive care unit admission was 10.6 (95% CI 9.5-11.7) for infants with birth defects. A stratified analysis identified birth defect categories with good, moderate, and poor prognoses. CONCLUSIONS This detailed information about mortality and morbidity of preterm VLBW infants with birth defects should be useful for genetic counseling as well as prenatal and neonatal care, with the limitation that we lacked information about the timing of diagnosis, abortion, or stillbirth.

Long-term survival of children born with congenital anomalies: A systematic review and meta-analysis of population-based studies. PLoS Med 2020; 17:e1003356. [PMID: 32986711 PMCID: PMC7521740 DOI: 10.1371/journal.pmed.1003356] [Citation(s) in RCA: 56] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 08/26/2020] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Following a reduction in global child mortality due to communicable diseases, the relative contribution of congenital anomalies to child mortality is increasing. Although infant survival of children born with congenital anomalies has improved for many anomaly types in recent decades, there is less evidence on survival beyond infancy. We aimed to systematically review, summarise, and quantify the existing population-based data on long-term survival of individuals born with specific major congenital anomalies and examine the factors associated with survival. METHODS AND FINDINGS Seven electronic databases (Medline, Embase, Scopus, PsycINFO, CINAHL, ProQuest Natural, and Biological Science Collections), reference lists, and citations of the included articles for studies published 1 January 1995 to 30 April 2020 were searched. Screening for eligibility, data extraction, and quality appraisal were performed in duplicate. We included original population-based studies that reported long-term survival (beyond 1 year of life) of children born with a major congenital anomaly with the follow-up starting from birth that were published in the English language as peer-reviewed papers. Studies on congenital heart defects (CHDs) were excluded because of a recent systematic review of population-based studies of CHD survival. Meta-analysis was performed to pool survival estimates, accounting for trends over time. Of 10,888 identified articles, 55 (n = 367,801 live births) met the inclusion criteria and were summarised narratively, 41 studies (n = 54,676) investigating eight congenital anomaly types (spina bifida [n = 7,422], encephalocele [n = 1,562], oesophageal atresia [n = 6,303], biliary atresia [n = 3,877], diaphragmatic hernia [n = 6,176], gastroschisis [n = 4,845], Down syndrome by presence of CHD [n = 22,317], and trisomy 18 [n = 2,174]) were included in the meta-analysis. These studies covered birth years from 1970 to 2015. Survival for children with spina bifida, oesophageal atresia, biliary atresia, diaphragmatic hernia, gastroschisis, and Down syndrome with an associated CHD has significantly improved over time, with the pooled odds ratios (ORs) of surviving per 10-year increase in birth year being OR = 1.34 (95% confidence interval [95% CI] 1.24-1.46), OR = 1.50 (95% CI 1.38-1.62), OR = 1.62 (95% CI 1.28-2.05), OR = 1.57 (95% CI 1.37-1.81), OR = 1.24 (95% CI 1.02-1.5), and OR = 1.99 (95% CI 1.67-2.37), respectively (p < 0.001 for all, except for gastroschisis [p = 0.029]). There was no observed improvement for children with encephalocele (OR = 0.98, 95% CI 0.95-1.01, p = 0.19) and children with biliary atresia surviving with native liver (OR = 0.96, 95% CI 0.88-1.03, p = 0.26). The presence of additional structural anomalies, low birth weight, and earlier year of birth were the most commonly reported predictors of reduced survival for any congenital anomaly type. The main limitation of the meta-analysis was the small number of studies and the small size of the cohorts, which limited the predictive capabilities of the models resulting in wide confidence intervals. CONCLUSIONS This systematic review and meta-analysis summarises estimates of long-term survival associated with major congenital anomalies. We report a significant improvement in survival of children with specific congenital anomalies over the last few decades and predict survival estimates up to 20 years of age for those born in 2020. This information is important for the planning and delivery of specialised medical, social, and education services and for counselling affected families. This trial was registered on the PROSPERO database (CRD42017074675).

Abstract
BACKGROUND Temperature instability has been observed in infants with trisomy 21 (T21) in the neonatal intensive care unit (NICU) but has not been described in the literature. METHODS All infants with T21 in the NICU 2011-2017 with at least 2 days of temperatures when ≥36 weeks PMA and not receiving external thermoregulation, and 2:1 matched controls were included. Prevalence and number of temperatures < 36 and >38 °C and infection workups were compared. RESULTS Hypothermia and hyperthermia were more common among T21 infants (n = 61) vs. controls: hypothermia 30% vs. 11% (p < 0.01); hyperthermia 16% vs. 8% (p = 0.13). Infants with T21 were more likely to have infection workups at the time of temperature instability (16% vs. 6%) but only one of ten workups was diagnostic of infection. CONCLUSIONS Temperature instability without infection is common among infants with T21 in the NICU.

[PMID: 32378275 DOI: 10.1111/jir.12735] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 04/03/2020] [Accepted: 04/09/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Regional heterogeneities and sociodemographic characteristics affect mortality and population survival in Brazil. However, for individuals with Down syndrome (DS) this information remains unknown. In this study, we analysed survival and mortality rates among DS individuals in the five Brazilian geographic regions. In addition, we investigated whether there is an association between mortality and sociodemographic factors across administrative regions. METHODS Data between 1996 and 2016, comprising 10 028 records of deaths of individuals with DS, were collected from database records of the Department of Informatics of the Unified Health System. Data on race/ethnicity, sex, age and years of schooling were defined for the association analyses. Survival data were analysed according to the Kaplan-Meier method and Cox regression model. RESULTS The number of deaths among people with DS has increased in recent years. Children are more susceptible to death, especially in the first years of life. Individuals living in the northern region, Indigenous women and people with no years of schooling have higher mortality. In the Southeast and South region, for White and Yellow, survival is related to a higher level of education. Ethnic factors and years of schooling influence risk for mortality across the administrative regions. CONCLUSIONS These findings show that sociodemographic characteristics affect survival and are associated with the risk of mortality for people with DS. In addition, this suggests that differences in access to health services among Brazilian regions, especially in the first years of life, may affect the survival of individuals with DS.

First Trimester Screening for Fetal Aneuploidies Using Placental Growth Factor: The Great Obstetrical Syndrome (GOS) Study. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2019; 40:1044-1049. [PMID: 30103877 DOI: 10.1016/j.jogc.2017.11.032] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2017] [Revised: 11/16/2017] [Accepted: 11/16/2017] [Indexed: 11/20/2022]
Abstract
OBJECTIVE This study sought to estimate the ability of first trimester maternal serum placental growth factor (PlGF) to identify fetal aneuploidies. METHODS A prospective cohort study of singleton pregnancy at 11 to 13 weeks was conducted. Maternal serum PlGF concentration was measured using BRAHMS PlGF plus KRYPTOR automated assays (Thermo Scientific BRAHMS, Hennigsdorf, Germany). PlGF and nuchal translucency were log-transformed and reported as multiples of the median (MoM) adjusted for crown-rump length. Detection rates were calculated using receiver-operator characteristic curves. RESULTS The study observed 21 cases of fetal aneuploidies (0.4%) out of 4765 participants. Trisomy 21 (13 cases; 0.85 MoM; interquartile range [IQR] 0.80-0.93), trisomy 18 (two cases; 0.77 MoM; IQR 0.66-0.87) and trisomy 13 (two cases; 0.68 MoM; IQR 0.61-0.75) were associated with low PlGF concentrations. The low PlGF values observed in the cases of monosomy X (two cases; 0.85 MoM; IQR 0.82-0.88, P = 0.05), triploidy (0.78 MoM, P = 0.11), and 47,XX,i(22)(p10) (0.18 MoM, P = 0.08) were not statistically different from the controls. A model including maternal age, nuchal translucency, and PlGF could have identified all (95% CI 83%-100%) cases of trisomy 21 and six of the other fetal aneuploidies (75%) at a false-positive rate of 9%. CONCLUSION Low first trimester PlGF is associated with an increased risk of fetal aneuploidy. PlGF combined with first trimester ultrasound (nuchal translucency, uterine artery Doppler, and early fetal anatomy) could identify not only women at high risk for preeclampsia, but also fetuses at high risk of aneuploidy for optimal further testing (non-invasive testing for common aneuploidy screening or chorionic villus sampling for full screening and diagnosis).

Abstract
OBJECTIVE To describe how trisomy 21 affects neonatal intensive care management and outcomes of full-term infants without congenital anomalies. STUDY DESIGN Retrospective cohort of full-term infants without anomalies with and without trisomy 21 admitted to Pediatrix NICUs from 2005 to 2012. We compared diagnoses, management, length of stay, and discharge outcomes. RESULTS In all, 4623 infants with trisomy 21 and 606 770 infants without trisomy 21 were identified. One-third of infants in the NICU with and without trisomy 21 were full term without major anomalies. Trisomy 21 infants had more respiratory distress, thrombocytopenia, feeding problems, and pulmonary hypertension. They received respiratory support for a longer period of time and had a longer length of stay. CONCLUSION One-third of infants with trisomy 21 admitted to the NICU are full term without major anomalies. Common diagnoses and greater respiratory needs place infants with trisomy 21 at risk for longer length of stay.

Palivizumab use in infants with Down syndrome-report from the German Synagis™ Registry 2009-2016. Eur J Pediatr 2018; 177:903-911.

Abstract
UNLABELLED Infants with Down syndrome (DS) face an increased risk of respiratory tract infections. Recent studies describe DS as independent risk factor for a complicated clinical course in infants with respiratory syncytial virus (RSV) infection. The prospective observational German Synagis™ Registry comprises data from 249 children below 25 months of age with DS and palivizumab prophylaxis 2009-2016 (1191 administrations; mean 4.8 per patient and season). The median gestational age and the birth weight in patients without and with DS were 31 versus 37 weeks (P < 0.001) and 1590 versus 2750 g, respectively (P < 0.001). Patients with DS significantly more often had congenital heart disease (CHD), siblings in kindergarten or school, treatment with oxygen at home, immunodeficiency, and neuromuscular impairment. The RSV-related hospitalization rate in patients with DS was 1.20%; the hospitalization rate in patients without DS was 0.71%. CONCLUSION Data from 249 children with DS receiving palivizumab prophylaxis in seven consecutive RSV seasons (2009-2016) in Germany reveal important differences between patients with and without DS concerning the main indication for palivizumab use and additional risk factors. Bearing in mind the limitations of an uncontrolled postmarketing observational study, the results confirm the field effectiveness of palivizumab prophylaxis in this special population. What is Known: • Recent studies describe the Down syndrome as independent risk factor for a complicated clinical course in infants with RSV infection. What is New: • Compared with other infants receiving palivizumab prophylaxis, patients with Down syndrome significantly more often had congenital heart disease, siblings in kindergarten or school, treatment with oxygen at home, immunodeficiency, and neuromuscular impairment. • In infants with palivizumab prophylaxis breakthrough, RSV-related hospitalization rates were not significantly higher in those with Down syndrome.

Abstract
Patients with Down syndrome (DS) may have multiple medical issues that place them at risk for requiring extracorporeal membrane oxygenation. Use of extracorporeal membrane oxygenation in pediatric patients with Down syndrome has been described, but minimal data exist for extracorporeal membrane oxygenation use in adults with Down syndrome. The goal of this study was to describe the clinical characteristics and to determine if there were differences between adult extracorporeal membrane oxygenation patients with Down syndrome that were alive (aDS) versus those that died (dDS) prior to hospital discharge. Patients with Down syndrome that were 18 years and older registered in the Extracorporeal Life Support Organization registry from 1983 to 2016 were analyzed. Demographics and extracorporeal membrane oxygenation characteristics were recorded. A total of 21 adults with Down syndrome were identified. Incidence of extracorporeal membrane oxygenation in adults with Down syndrome was 0.88 per 1000 extracorporeal membrane oxygenation procedures. Hospital mortality was 57.1% (12/21). There were no significant differences between aDS versus dDS for age (24.9 ± 4.8 vs. 28.1 ± 10.2 years), weight (90.7 ± 13.0 vs. 79.1 ± 27.0 kg), gender (4 males vs. 8 males), initial pH (7.18 ± 0.19 vs. 7.27 ± 0.16), or initial pO2 (51.7 ± 13.9 vs. 45.4 ± 19.9), respectively. There were no significant differences between aDS versus dDS in duration of extracorporeal membrane oxygenation run (239 ± 159 h vs. 455 ± 570 h, respectively), ventilator or extracorporeal membrane oxygenation mode, and nitric oxide use. aDS had fewer incidences of mechanical and neurologic complications (41.7% vs. 0.0%, P < 0.05) versus dDS. There were no other significant differences in complication rates between the two groups. Use of extracorporeal membrane oxygenation in the adult population with Down syndrome is significantly less compared to the pediatric population with Down syndrome. Baseline characteristics are not predictive of overall survival. There were minimal differences noted between aDS versus dDS during their extracorporeal membrane oxygenation course. Mortality rates are similar to non-Down syndrome patients placed on extracorporeal membrane oxygenation. Extracorporeal membrane oxygenation may be a reasonable option for adult patients with Down syndrome requiring intensive care.

Abstract
OBJECTIVE Neonates with Down's syndrome (nDS) may have multiple medical issues that place them at increased risk for mortality during the newborn period. Goal of this study was to determine if there are differences in baseline characteristics, medical complications or procedures performed during hospitalization between nDS who survived versus those who died during initial hospitalization. STUDY DESIGN Data from 2000 to 2014 were reviewed using the Pediatric Health Information Systems (PHIS) database on all DS patients admitted to the hospital <30 days postnatal life. Baseline demographics, medical complications, procedures performed and mortality were recorded. Patients were divided into nDS patients who were discharged alive (nDS-a) versus nDS patients who died (nDS-d). Multivariate logistic analysis with odds ratios was performed to determine significant predictors of death. A P<0.05 was considered significant. RESULTS A total of 5737 nDS were evaluated. Overall mortality was 7.5% (431/5737). nDS-d were more likely than nDS-a to have a lower birth weight (1.0 (0.9 to 1.0)), presence of a diaphragmatic hernia (6.9 (1.9 to 25.1), or a cardiac diagnosis of a pulmonary venous abnormality (6.8 (1.9 to 24.4)), Ebstein's anomaly (3.2 (1.2 to 8.5)) or left-sided obstructive lesion (2.0 (1.3 to 3.0). nDS-d were more likely to develop hydrops (5.7 (3.5 to 9.5)) and necrotizing enterocolitis (1.7 (1.2 to 2.6)). In addition, nDS-d had significantly higher odds of requiring mechanical ventilation (20.7 (9.9 to 43.1)) or extracorporeal membrane oxygenation (8.7 (4.7 to 16.1)). CONCLUSIONS A number of characteristics, specifically certain cardiac diagnosis, place nDS at increased risk for mortality. Furthermore, development of specific medical complications or need for particular procedures increases the odds for mortality in nDS. Caregivers should be cognizant that they are taking care of a high-risk population nDS with an increased risk for mortality if these variables are present.

Abstract
AIM The prevalence of Down syndrome in infants with fetal ventriculomegaly is 5% to 10%; however, the converse, the prevalence of cerebral ventriculomegaly in live-born infants with Down syndrome, is not well established. Because cranial ultrasounds are performed on most very-low-birthweight (VLBW) infants (birthweight <1500g), our aim was to examine ultrasound abnormalities of VLBW infants to determine prevalence of ventriculomegaly and intraventricular hemorrhage (IVH) in VLBW infants with Down syndrome, and whether VLBW infants with Down syndrome are at higher risk for cranial ultrasound abnormalities, compared with the already elevated risk in other VLBW infants. METHOD This study comprised retrospective analysis of data from Pediatrix BabySteps Clinical Data Warehouse. The study population consisted of 121 736 VLBW infants (61 869 males, 59 867 females), born between 1996 and 2013, of whom 441 had Down syndrome (233 males, 208 females; mean gestational age 30wks, standard deviation [SD] 2.8wks). Logistic regression was used to calculate odds of ventriculomegaly and IVH for Down syndrome. RESULTS Prevalence of ventriculomegaly in Down syndrome was 5.2% compared with 0.8% in other VLBW infants. Multivariate analysis indicated 5.8× odds (95% confidence interval [CI] 3.4-9.7) of ventriculomegaly in Down syndrome and 0.9× odds (95% CI 0.7-1.1) of IVH for Down syndrome. INTERPRETATION Very preterm infants with Down syndrome are at increased risk for ventriculomegaly (but not for IVH) compared with other infants born very preterm.

Abstract
BACKGROUND Neonates with Down syndrome (DS) weigh less, are smaller and have increased first-year mortality, especially if born small for gestational age (GA). DS-specific GA-related neonatal anthropometrics for Germany are lacking. OBJECTIVES To construct reference tables and centile curves for birth weight (g), crown-heel length (cm) and head circumference (cm) by sex and GA for German DS neonates. METHODS Retrospective anthropometric data from live-born singleton DS neonates born in Germany from January 1966 to June 2010 were collected using standardized questionnaires and patient records. Reference tables were created based on means and standard deviations. The 3rd, 10th, 25th, 50th, 75th, 90th and 97th centile curves were constructed and smoothed using running medians and Cole's LMS method. RESULTS Anthropometric measurements were obtained for 1,304 DS neonates [males/females: 713/591 (54.7%/45.3%)]. Reference tables and centile charts were constructed from 3,542 (males/females: 1,932/1,610) observations for GA 32-41 weeks. Compared with general-population newborns, prematurity was increased (21.1 vs. 6.3%) at GA 32-36 weeks. Term-born (GA 40 weeks) male and female DS neonates were 352.5 and 223.5 g lighter and 1.5 and 1.4 cm smaller than general-population neonates, and head circumference was also 1.4 and 1.5 cm smaller, respectively. CONCLUSION This is the first study to report GA-related, sex-specific reference tables and centile charts of birth weight, length and head circumference for DS neonates born in Germany. Compared with the general German population, DS newborns are more frequently born prematurely, weigh less, are smaller and have a smaller head circumference at birth.

Abstract
BACKGROUND AND OBJECTIVES Trisomy 21 is known to decrease the risk of several (nonocular) angiogenic-mediated diseases. The objective of this study was to determine whether trisomy 21 can also be shown to be significantly protective against ocular angiogenic-mediated disorders such as retinopathy of prematurity (ROP). METHODS A retrospective analysis of deidentified data from the Pediatrix BabySteps Clinical Warehouse. This large repository of neonatal data is approved for use in research studies by the Western Institutional Review Board. The study population consisted of 99,080 infants with very low birth weights (BWs; BW <1500 g), born between 1996 and 2013, cared for at >300 US NICUs, and who had been discharged alive from hospital. Statistical significance for unadjusted comparisons between groups was determined with Pearson's χ(2) test or Student's t test. Logistic regression models were used to calculate the odds of ROP (of any stage) and advanced ROP (stage 3 or greater) for infants with trisomy 21 compared with all other infants. RESULTS The prevalence of trisomy 21 was 0.3% in the study population (321 of 99,080). After adjustment for BW, gestational age, oxygen exposure, and other potential confounders, there was an odds ratio of 0.6 (95% confidence interval: 0.5-0.8) for ROP in infants with trisomy 21compared with other infants and an odds ratio of 0.4 (95% confidence interval: 0.1-0.9) for advanced-stage ROP. CONCLUSIONS Trisomy 21 significantly decreases the odds for ROP in very low BW infant survivors. This study unmasks a potentially identifiable genetic component to ROP risk, paving the way for the development of a laboratory-based ROP screening tool.

Abstract
There is concern at the National Heart, Lung, and Blood Institute (NHLBI) and among transfusion medicine specialists regarding the small number of investigators and studies in the field of pediatric transfusion medicine (PTM). Accordingly, the objective of this article is to provide a snapshot of the clinical and translational PTM research considered to be of high priority by pediatricians, neonatologists, and transfusion medicine specialists. Included is a targeted review of three research areas of importance: (i) transfusion strategies, (ii) short- and long-term clinical consequences, and (iii) transfusion-transmitted infectious diseases. The recommendations by PTM and transfusion medicine specialists represent opportunities and innovative strategies to execute translational research, observational studies, and clinical trials of high relevance to PTM. With the explosion of new biomedical knowledge and increasingly sophisticated methodologies over the past decade, this is an exciting time to consider transfusion medicine as a paradigm for addressing questions related to fields such as cell biology, immunology, neurodevelopment, outcomes research, and many others. Increased awareness of PTM as an important, fertile field and the promotion of accompanying opportunities will help establish PTM as a viable career option and advance basic and clinical investigation to improve the health and wellbeing of children.

Abstract
OBJECTIVE This study tested the hypothesis that feeding an exclusively human milk (EHM) diet to premature infants reduces the incidence of necrotizing enterocolitis (NEC) associated with enteral feeding. STUDY DESIGN An observational study for infants born at less than 33 weeks of gestational age was performed in a single neonatal intensive care unit. An EHM diet prospectively eliminated bovine-based artificial milk, including bovine-based fortifier, through 33 weeks postmenstrual age (PMA). The clinical data from a 2.5-year interval of the EHM diet were compared with data from the previous 6.5 years for similar infants who received bovine-based milk products before 33 weeks PMA. RESULTS In the EHM diet cohort, 148 of 162 infants (91%) received EHM through 33 weeks PMA. In order to achieve an EHM diet, 140 of 162 infants (86%) received their own mother's milk, and 98 of 162 infants (60%) received donor human milk. The EHM cohort was also fed a human milk-based fortifier to truly eliminate bovine products. The distribution of NEC onset in the EHM cohort was significantly different from that in the control cohort for the day of onset (p=0.042) and the PMA at onset (p=0.011). In the control cohort, NEC onset after Day 7 of life occurred in 15 of 443 infants (3.4%), significantly more than in the EHM cohort where NEC occurred in two of 199 infants (1%) (p=0.009). CONCLUSIONS Changing to an EHM milk diet through 33 weeks PMA reduced the incidence of NEC associated with enteral feeding.

Abstract
OBJECTIVE Birth defects (BDs) are an important cause of infant mortality and disproportionately occur among low birth weight infants. We determined the prevalence of BDs in a cohort of very low birth weight (VLBW) infants cared for at the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network (NRN) centers over a 10-year period and examined the relationship between anomalies, neonatal outcomes, and surgical care. METHODS Infant and maternal data were collected prospectively for infants weighing 401 to 1500 g at NRN sites between January 1, 1998, and December 31, 2007. Poisson regression models were used to compare risk of outcomes for infants with versus without BDs while adjusting for gestational age and other characteristics. RESULTS A BD was present in 1776 (4.8%) of the 37 262 infants in our VLBW cohort. Yearly prevalence of BDs increased from 4.0% of infants born in 1998 to 5.6% in 2007, P < .001. Mean gestational age overall was 28 weeks, and mean birth weight was 1007 g. Infants with BDs were more mature but more likely to be small for gestational age compared with infants without BDs. Chromosomal and cardiovascular anomalies were most frequent with each occurring in 20% of affected infants. Mortality was higher among infants with BDs (49% vs 18%; adjusted relative risk: 3.66 [95% confidence interval: 3.41-3.92]; P < .001) and varied by diagnosis. Among those surviving >3 days, more infants with BDs underwent major surgery (48% vs 13%, P < .001). CONCLUSIONS Prevalence of BDs increased during the 10 years studied. BDs remain an important cause of neonatal morbidity and mortality among VLBW infants.

Abstract
OBJECTIVE This study examined changes in survival among children with Down syndrome (DS) by race/ethnicity in 10 regions of the United States. A retrospective cohort study was conducted on 16,506 infants with DS delivered during 1983-2003 and identified by 10 US birth defects monitoring programs. Kaplan-Meier survival probabilities were estimated by select demographic and clinical characteristics. Adjusted hazard ratios (aHR) were estimated for maternal and infant characteristics by using Cox proportional hazard models. RESULTS The overall 1-month and 1-, 5-, and 20-year survival probabilities were 98%, 93%, 91%, and 88%, respectively. Over the study period, neonatal survival did not improve appreciably, but survival at all other ages improved modestly. Infants of very low birth weight had 24 times the risk of dying in the neonatal period compared with infants of normal birth weight (aHR 23.8; 95% confidence interval [CI] 18.4-30.7). Presence of a heart defect increased the risk of death in the postneonatal period nearly fivefold (aHR 4.6; 95% CI 3.9-5.4) and continued to be one of the most significant predictors of mortality through to age 20. The postneonatal aHR among non-Hispanic blacks was 1.4 (95% CI 1.2-1.8) compared with non-Hispanic whites and remained elevated by age 10 (2.0; 95% CI 1.0-4.0). CONCLUSIONS The survival of children born with DS has improved and racial disparities in infant survival have narrowed. However, compared with non-Hispanic white children, non-Hispanic black children have lower survival beyond infancy. Congenital heart defects are a significant risk factor for mortality through age twenty.

Abstract
OBJECTIVE To examine the influence of fetal and maternal characteristics on the survival of children born with Down syndrome. METHODS We used prospectively collected population-based data on Down syndrome extracted from the UK Northern Congenital Abnormality Survey (NorCAS), January 1, 1985-December 31, 2003, matched to hospital and national mortality records to January 29, 2008, to determine survival status of liveborn children. Survival to 20 years was estimated by using Kaplan-Meier methods. Cox proportional hazards regression was used to examine factors that predict survival. RESULTS A total of 1115 Down syndrome pregnancies were notified to NorCAS during the 19 years, a total prevalence of 16.8 (95% CI, 15.8-17.8) per 10,000 live births and stillbirths. Of these, 5.4% resulted in a spontaneous fetal loss (late miscarriage ≥ 20 weeks and stillbirth), 31.7% in a termination of pregnancy, and 63.0% in a live birth. Survival status was known for 95.3% of live births; 16.6% resulted in a death. Year of birth (P < .001), gestational age at delivery (P < .001), standardized birth weight (P < .001), karyotype (P < .01), and presence of additional structural anomalies (P < .001) were significant predictors of survival. Infant gender, plurality, maternal age, and maternal deprivation were not significant predictors of survival. CONCLUSIONS These robust estimates of predictors of survival are important for the prenatal counseling of parents whose pregnancy is affected by Down syndrome and for health care planning for the future care needs of these children.
