Abstract
OBJECTIVE No available scale, at the time of initial evaluation for necrotizing enterocolitis (NEC), accurately predicts, that is, with an area under the curve (AUC) ≥0.9, which preterm infants will undergo surgery for NEC stage III or die within a week. STUDY DESIGN This is a retrospective cohort study (n = 261) of preterm infants with <33 weeks' gestation or <1,500 g birth weight with either suspected or with definite NEC born at Parkland Hospital between 2009 and 2021. A prediction model using the new HASOFA score (Hyperglycemia, Hyperkalemia, use of inotropes for Hypotension during the prior week, Acidemia, Neonatal Sequential Organ Failure Assessment [nSOFA] score) was compared with a similar model using the nSOFA score. RESULTS Among 261 infants, 112 infants had NEC stage I, 68 with NEC stage II, and 81 with NEC stage III based on modified Bell's classification. The primary outcome, surgery for NEC stage III or death within a week, occurred in 81 infants (surgery in 66 infants and death in 38 infants). All infants with pneumoperitoneum or abdominal compartment syndrome either died or had surgery. The HASOFA and the nSOFA scores were evaluated in 254 and 253 infants, respectively, at the time of the initial workup for NEC. Both models were internally validated. The HASOFA model was a better predictor of surgery for NEC stage III or death within a week than the nSOFA model, with greater AUC 0.909 versus 0.825, respectively, p < 0.001. Combining HASOFA at initial assessment with concurrent or later presence of abdominal wall erythema or portal gas improved the prediction surgery for NEC stage III or death with AUC 0.942 or 0.956, respectively. CONCLUSION Using this new internally validated prediction model, surgery for NEC stage III or death within a week can be accurately predicted at the time of initial assessment for NEC. KEY POINTS · No available scale, at initial evaluation, accurately predicts which preterm infants will undergo surgery for NEC stage III or die within a week.. · In this retrospective cohort study of 261 preterm infants with either suspected or definite NEC we developed a new prediction model (HASOFA score).. · The HASOFA-model had high discrimination (AUC: 0.909) and excellent calibration and was internally validated..

Abstract
OBJECTIVE The aim of this study was to determine which late-preterm (35-36 weeks' gestational age [GA]) and term neonates with early-onset hypoglycemia in the first 72 hours postnatal required a continuous glucose infusion to achieve and successfully maintain euglycemia. STUDY DESIGN This is a retrospective cohort study of late preterm and term neonates born in 2010-2014 and admitted to the Mother-Baby Unit at Parkland Hospital who had laboratory-proven blood glucose concentration < 40 mg/dL (2.2 mmol/L) during the first 72 hours of life. Among the subgroup needing intravenous (IV) glucose infusion, we analyzed which factors predicted a maximum glucose infusion rate (GIR) ≥ 10 mg/kg/min. The entire cohort was randomly divided into a derivation cohort (n = 1,288) and a validation cohort (n = 1,298). RESULTS In multivariate analysis, the need for IV glucose infusion was associated with small size for GA, low initial glucose concentration, early-onset infection, and other perinatal variables in both cohorts. A GIR ≥ 10 mg/kg/min was required in 14% of neonates with blood glucose value < 20 mg/dL during the first 3 hours of observation. The likelihood of a GIR ≥ 10 mg/kg/min was associated with lower initial blood glucose value and lower umbilical arterial pH. CONCLUSION Need for IV glucose infusion was associated with small size for GA, low initial glucose concentration, early-onset infection, and variables associated with perinatal hypoxia-asphyxia. The likelihood of a maximum GIR ≥ 10 mg/kg/min was greater in neonates with lower blood glucose value during the first 3 hours of observation and lower umbilical arterial pH. KEY POINTS · We studied 51,973 neonates ≥ 35 weeks' GA.. · We established a model predicting the need for IV glucose.. · We also predicted the need for a high rate of IV glucose..

Abstract
OBJECTIVE Necrotizing enterocolitis (NEC) primarily affects preterm, especially small for gestational age (SGA), infants. This study was designed to (1) describe frequency and timing of NEC in SGA versus non-SGA infants and (2) assess whether NEC is independently associated with the severity of intrauterine growth failure. STUDY DESIGN Retrospective cohort study of infants without severe congenital malformations born <33 weeks' gestational age (GA) carried out from 2009 to 2021. The frequency and time of NEC were compared between SGA and non-SGA infants. Multivariate logistic regression was used to assess whether NEC was independently associated with intrauterine growth restriction. Severe growth restriction was defined as birth weight Z-score < -2. RESULTS Among 2,940 infants, the frequency of NEC was higher in SGA than in non-SGA infants (25/268 [9.3%] vs. 110/2,672 [4.1%], respectively, p < 0.001). NEC developed 2 weeks later in SGA than non-SGA infants. In multivariate analysis, the adjusted odds of NEC increased with extreme prematurity (<28 weeks' GA) and with severe but not moderate growth restriction. The adjusted odds of NEC increased with urinary tract infection or sepsis within a week prior to NEC, were lower in infants fed their mother's own milk until discharge, and did not change over five epochs. NEC was independently associated with antenatal steroid (ANS) exposure in infants with birth weight (BW) Z-score < 0. CONCLUSION NEC was more frequent in SGA than in non-SGA infants and developed 2 weeks later in SGA infants. NEC was independently associated with severe intrauterine growth failure and with ANS exposure in infants with BW Z-score < 0. KEY POINTS · We studied 2,940 infants <33 weeks' GA.. · We assessed NEC.. · NEC was more frequent in SGA infants.. · NEC occurred 2 weeks later in SGA infants.. · NEC was associated with severe growth restriction..

Abstract
OBJECTIVE This study aimed to develop a predictive model of feeding mother's own milk (MOM) at discharge using social determinants of health (SDOH), maternal and neonatal factors after deliveries at <33 weeks of gestational age (GA), or birth weight <1,500 g. STUDY DESIGN Secondary analysis of a retrospective cohort in an inner-city hospital before (Epoch-1, 2018-2019) and after (Epoch-2, 2020-2021) implementing a donor human milk (DHM) program. RESULTS Among 986 neonates, 495 were born in Epoch-1 (320 Hispanic White, 142 Non-Hispanic Black, and 33 Other) and 491 in Epoch-2 (327, 137, and 27, respectively). Feeding any MOM was less frequent in infants of non-Hispanic Black mothers than in those of Hispanic mothers (p < 0.05) but did not change with epoch (p = 0.46). Among infants who received any MOM, continued feeding MOM to the time of discharge was less frequent in infants of non-Hispanic Black mothers versus those of Hispanic mothers, 94/237 (40%) versus 339/595 (57%; p < 0.05), respectively. In multivariate analysis including SDOH and maternal variables, the odds of feeding MOM at discharge were lower with SDOH including neighborhoods with higher poverty levels, multiparity, substance use disorder, non-Hispanic Black versus Hispanic and young maternal age and increased with GA but did not change after implementing DHM. The predictive model including SDOH, maternal and early neonatal variables had good discrimination (area under the curve 0.85) and calibration and was internally validated. It showed the odds of feeding MOM at discharge were lower in infants of non-Hispanic Black mothers and with feeding DHM, higher need for respiratory support and later initiation of feeding MOM. CONCLUSION Feeding MOM at discharge was associated with SDOH, and maternal and neonatal factors but did not change after implementing DHM. Disparity in feeding MOM at discharge was explained by less frequent initiation and shorter duration of feeding MOM but not by later initiation of feeding MOM. KEY POINTS · In this cohort study of preterm infants, factors of feeding MOM at discharge included (1) SDOH; (2) postnatal age at initiation of feeding MOM; and (3) maternal and neonatal factors.. · Feeding MOM at the time of discharge was less frequent in infants of non-Hispanic Black mothers versus those of Hispanic mothers.. · Disparity in feeding MOM at discharge was explained by less frequent initiation and shorter duration of MOM feeding but not by later postnatal age at initiation of feeding MOM..

Abstract
Infants with severe bronchopulmonary dysplasia may require high doses of neurosedative medications to ensure pain control and stability following tracheostomy placement. Subsequent weaning of these medications safely and rapidly is a challenge. We describe a 24-hour propofol infusion to reduce neurosedative medications in 3 high-risk infants following tracheostomy placement.

Abstract
OBJECTIVE Neonates born with fetal inflammatory response (FIR) are at increased risk for adverse neonatal outcomes. Our objective was to determine whether FIR and its severity is associated with severity of necrotizing enterocolitis (NEC) in preterm infants. METHODS A case-control retrospective study of infants <33 weeks gestational age or <1500 g birthweight, including 260 with stage I-III NEC and 520 controls matched for gestational age. Placental pathology was evaluated, and FIR progression and its severity were defined according to Amsterdam classification. RESULTS In this study, mild FIR (i.e., stage 1 FIR) was present in 52 controls (10.0%) and 22 infants with stage I-III NEC (8.5%), while moderate to severe FIR (i.e., ≥stage 2 FIR) was present in 16 controls (3.1%) and 47 infants with stage I-III NEC (18.1%). Both stage and grade of FIR were associated with stage of NEC (P < 0.001). On multinomial logistic regression, stage III NEC was associated with stage of FIR (P < 0.001). CONCLUSION This is the first report demonstrating the association between progression and increasing severity of FIR and stage of NEC. IMPACT Fetal Inflammatory Response (FIR) and its progression and severity are associated with the stages of necrotizing enterocolitis (NEC). This is the first study demonstrating the impact of progression and severity of FIR on stage III NEC. These observations provide additional insight into understanding the impact of intrauterine exposure to inflammation on the severity of NEC in preterm infants.

Abstract
BACKGROUND Donor breast milk (DBM) feeding has been associated with less growth than formula in preterm infants. Zinc content in DBM is insufficient to support growth in preterm infants. OBJECTIVE To compare growth from birth to discharge, macro- and micronutrient intake and the frequency of poor growth before (Epoch-1) and after (Epoch-2) implementing a DBM program. METHODS Retrospective cohort study of 1069 infants born at < 33 weeks' gestational age or birthweight < 1500 g and fed using our adjustable feeding protocol with accurate serial length measurements. Growth was assessed by changes in Z-scores of weight, length and fronto-occipital circumference from birth to discharge. RESULTS Growth did not decrease significantly in Epoch-2. However, energy and protein intake increased by 5% and frequency of zinc and vitamin D supplementation increased by >30%. CONCLUSIONS DBM implementation did not significantly decrease growth from birth to discharge using our adjustable feeding protocol.

Abstract
Background Very low birth weight (VLBW: ≤1500 g) is associated with multiple short and long-term complications. This study aimed to examine outcomes and predictors of functioning, mental health, and health-related quality of life in adults born with VLBW. Methods In this prospective longitudinal cohort study, 67 VLBW and 102 control participants were assessed using the Adult Self-Report of the Achenbach System of Empirically Based Assessment and Global Assessment of Functioning at 26 years, and the Hospital Anxiety and Depression Scale and Short Form-36 at 28 years of age. Associations between perinatal and childhood predictors and adult functioning were assessed using linear regression. Results Compared with controls, the VLBW group had lower mean raw scores on the Function and Symptom subscales of the Global Assessment of Functioning at 26 years, a higher sum score of symptoms of anxiety and depression due to more depressive symptoms, and poorer mental health-related quality of life at 28 years. The mean group differences ranged from 0.42 to 0.99 SD. Within the VLBW group, lower birth weight and gestational age, a higher number of days with respiratory support and poorer motor function at 14 years were associated with a higher sum score of symptoms of anxiety and depression at 28 years. Days with respiratory support and motor function at 14 years were also predictive of Global Assessment of Functioning scores at 26 years, and mental health-related quality of life at 28 years. Poorer motor and cognitive function at five years were associated with poorer physical health-related quality of life at 28 years. Parental socioeconomic status was related to mental and physical health-related quality of life. Conclusion In this study, VLBW adults reported poorer functioning and mental health-related quality of life, and more depressive symptoms than their term born peers. Days with respiratory support and adolescent motor function predicted most of the adult outcomes. This study explicates perinatal and developmental markers during childhood and adolescence which can be target points for interventions.

Abstract
BACKGROUND Randomized trials of antenatal steroid administration (ANS) for extreme or moderate preterm pregnancies excluded women with diabetes mellitus (DM) and included few with preeclampsia. METHODS Cohort study (n = 1,813) including moderate preterm births [290/7-336/7wks' gestational age GA)] before (Epoch-1) and after (Epoch-2) expansion of ANS administration to women with hypertensive disorders (HTN) and/or DM. We compared surfactant administration in Group-1 (neither HTN nor DM), Group-2a (HTN not DM), Group-2b (DM not HTN) and Group-2c (DM and HTN). RESULTS Surfactant administration was less frequent after ANS in Group-1 [adjusted odds ratio (aOR) 0.54, 95% confidence interval (CI) 0.31, 0.93, P = 0.03], Group-2a (aOR 0.36, CI 0.22, 0.58, P < 0.001) and Group-2c (aOR 0.29, CI 0.12, 0.71, P = 0.007) but not Group-2b (P = 0.64). CONCLUSIONS ANS administration was independently associated with less surfactant administration in moderately preterm neonates whose mothers had neither HTN nor DM, and those with HTN, but not those with DM without HTN.

Abstract
BACKGROUND AND OBJECTIVE To assess the racial and ethnic disparity in the prevalence of complex chronic conditions (CCC) and/or in-hospital death among US-born very low birth weight (VLBW, <1500 g) infants. METHODS This retrospective, cross-sectional analysis of discharge data from the Kids' Inpatient Database, included VLBW infants born in US hospitals in 2009 and 2012 (n = 554825, weighted n = 573693) exlcuding those with missing demographics. The main outcome was CCC or death. Multiple logistic regression modeling estimated the association of various characteristics with CCC or death, considering race and ethnicity. RESULTS There was heterogeneity in the association of insurance status and hospital region and experiencing CCC or death when compared across races and ethnicities. Infants of all races and ethnicities had higher odds of CCC or death if they had an operative procedure, were outborn, or had a birth weight of <500 g or 500 g to 999 g compared with 1000 g to 1499 g. Non-Hispanic Black infants <500 g, however, had the highest odds of CCC or death compared with those 1000 g to 1499 g (adjusted odds ratio 67.2, 95% confidence interval, 48.6-93.0), 2.3 times higher than the odds for non-Hispanic White infants (AOR 2.32, 95% confidence interval, 1.57-3.42). CONCLUSIONS Insurance and region were associated with increased prevalence of CCC or death in certain racial and ethnic groups. Additionally, non-Hispanic Black infants <500 g had >2.3 times the odds of CCC or death compared with non-Hispanic White infants, relative to infants 1000 g to 1499 g. Additional investigation is needed to understand the drivers of these disparities.

Association of antenatal steroids with neonatal mortality and morbidity in preterm infants born to mothers with diabetes mellitus and hypertension. J Perinatol 2021; 41:1660-1668. [PMID: 34035455 DOI: 10.1038/s41372-021-01090-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 04/14/2021] [Accepted: 04/29/2021] [Indexed: 11/09/2022]
Abstract
BACKGROUND Randomized trials of antenatal steroids (ANS) included women at 24-33 weeks gestational age (GA); however, few women had preeclampsia and women with diabetes mellitus (DM) were excluded. METHODS Cohort study including preterm births at 230/7-286/7 weeks GA before (Epoch-1) and after (Epoch-2) expansion of ANS administration to women with DM and hypertensive disorders (HTN). We compared Group-A (neither DM nor HTN) and Group-B (DM and/or HTN). RESULTS Among 747 neonates the adjusted odds ratio (aOR) for surfactant administration, in-hospital mortality, severe intraventricular hemorrhage (IVH) and death or severe IVH were lower in ANS-exposed neonates than unexposed neonates. In Group-B, ANS administration was independently associated with less severe IVH and less death or severe IVH, but not less surfactant use or mortality. CONCLUSIONS Increased ANS administration in women with DM and/or HTN was independently associated with less severe IVH and less death or severe IVH but without decrease in surfactant administration.

Abstract
BACKGROUND AND OBJECTIVES Very low birth weight (VLBW) infants are at high risk for morbidities beyond the neonatal period and ongoing use of health care. Specific morbidities have been studied; however, a comprehensive landscape of medical complexity in VLBW infants has not been fully described. We sought to (1) describe the prevalence of complex chronic conditions (CCCs) and (2) determine the association of demographic, hospital, and clinical factors with CCCs and CCCs or death. METHODS This retrospective cross-sectional analysis of discharge data from the Kids' Inpatient Database (2009-2012) included infants with a birth weight <1500 g and complete demographics. Outcomes included having CCCs or having either CCCs or dying. Analyses were weighted; univariate and multiple logistic regression models were used to estimate unadjusted and adjusted odds ratios. A dominance analysis with Cox-Snell R 2 determined the relative contribution of demographic, hospital, and clinical factors to the outcomes. RESULTS Among our weighted cohort of >78 000 VLBW infants, >50% had CCCs or died. After adjustments, the prevalence of CCCs or CCCs or death differed by sex, race and ethnicity, hospital location, US region, receipt of surgery, transfer status, and birth weight. Clinical factors accounted for the highest proportion of the model's ability to predict CCCs and CCCs or death at 93.3% and 96.3%, respectively, whereas demographic factors were 11.5% and 2.3% and hospital factors were 5.2% and 1.4%, respectively. CONCLUSIONS In this nationally representative analysis, medical complexity is high among VLBW infants. Varying contributions of demographic, hospital, and clinical factors in predicting medical complexity offer opportunities to investigate future interventions to improve care delivery and patient outcomes.

A Model of Germinal Matrix Hemorrhage in Preterm Rat Pups. Front Cell Neurosci 2020; 14:535320. [PMID: 33343300 PMCID: PMC7744792 DOI: 10.3389/fncel.2020.535320] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Accepted: 11/05/2020] [Indexed: 01/26/2023] Open
Abstract
Germinal matrix hemorrhage (GMH) is a serious complication in extremely preterm infants associated with neurological deficits and mortality. The purpose of the present study was to develop and characterize a grade III and IV GMH model in postnatal day 5 (P5) rats, the equivalent of preterm human brain maturation. P5 Wistar rats were exposed to unilateral GMH through intracranial injection into the striatum close to the germinal matrix with 0.1, 0.2, or 0.3 U of collagenase VII. During 10 days following GMH induction, motor functions and body weight were assessed and brain tissue collected at P16. Animals were tested for anxiety, motor coordination and motor asymmetry on P22–26 and P36–40. Using immunohistochemical staining and neuropathological scoring we found that a collagenase dose of 0.3 U induced GMH. Neuropathological assessment revealed that the brain injury in the collagenase group was characterized by dilation of the ipsilateral ventricle combined with mild to severe cellular necrosis as well as mild to moderate atrophy at the levels of striatum and subcortical white matter, and to a lesser extent, hippocampus and cortex. Within 0.5 h post-collagenase injection there was clear bleeding at the site of injury, with progressive increase in iron and infiltration of neutrophils in the first 24 h, together with focal microglia activation. By P16, blood was no longer observed, although significant gray and white matter brain infarction persisted. Astrogliosis was also detected at this time-point. Animals exposed to GMH performed worse than controls in the negative geotaxis test and also opened their eyes with latency compared to control animals. At P40, GMH rats spent more time in the center of open field box and moved at higher speed compared to the controls, and continued to show ipsilateral injury in striatum and subcortical white matter. We have established a P5 rat model of collagenase-induced GMH for the study of preterm brain injury. Our results show that P5 rat pups exposed to GMH develop moderate brain injury affecting both gray and white matter associated with delayed eye opening and abnormal motor functions. These animals develop hyperactivity and show reduced anxiety in the juvenile stage.

Abstract
OBJECTIVES To determine the prevalence of children with complex chronic conditions in PICUs in Argentina. To describe the demographic profile, clinical course and outcomes in PICU of children with complex chronic condition in comparison to previously healthy children. DESIGN Prospective, observational multicenter study. SETTING Nineteen PICUs located in Argentina belonging to public and private institutions. PATIENTS All children admitted to the participating PICUs between March 1, 2015, and February 28, 2016. INTERVENTIONS None. MEASUREMENT AND MAIN RESULTS We analyzed 3,483 PICU admissions. The prevalence of complex chronic condition was 48.06% (95% CI, 46.39-49.72). Cardiovascular complex chronic condition was predominant (22.24% [421/1,893]), followed by neuromuscular complex chronic condition (18.75% [355/1,893]) and malignant disease 17.7% (335/1,893). Technologic dependence was present in 22.22% of the patients (372 of 1,674). Predominant admission diagnosis was postoperative (36.6%) and respiratory disease (28.32%). Children with complex chronic condition had higher mortality than previously healthy patients (odds ratio, 2.74; 95% CI, 2.01-3.73). The risk of prolonged stay (≥ 26 d) was also higher (odds ratio, 1.44; 95% CI, 1.10-1.89). Rate utilization of the following devices was higher in patients with complex chronic condition: mechanical ventilation (odds ratio, 1.35; 95% CI, 1.12-1.63), central venous catheter (odds ratio, 1.24; 95% CI, 1.04-1.48), and arterial monitoring (odds ratio, 1.33; 95% CI, 1.09-1.63). CONCLUSIONS We observed a high prevalence of patients with complex chronic condition in this sample of argentine PICUs. These patients presented higher mortality and resource use than previously healthy children. This information is valuable to understand the impact that patients with complex chronic condition have on PICU performance and enables proper planning of care.

Abstract
OBJECTIVES To evaluate if obesity is associated with increased angiotensin II (Ang II) and decreased angiotensin-(1-7) or Ang-(1-7) in the circulation and urine among adolescents born prematurely. STUDY DESIGN In a cross-sectional analysis of 175 14-year-olds born preterm with very low birth weight, we quantified plasma and urinary Ang II and Ang-(1-7) and compared their levels between subjects with overweight/obesity (body mass index ≥85th percentile, n = 61) and those with body mass index <85th percentile (n = 114) using generalized linear models, adjusted for race and antenatal corticosteroid exposure. RESULTS Overweight/obesity was associated with higher systolic blood pressure and a greater proportion with high blood pressure. After adjustment for confounders, overweight/obesity was associated with an elevated ratio of plasma Ang II to Ang-(1-7) (β: 0.57, 95% CI 0.23-0.91) and higher Ang II (β: 0.21 pmol/L, 95% CI 0.03-0.39) but lower Ang-(1-7) (β: -0.37 pmol/L, 95% CI -0.7 to -0.04). Overweight/obesity was associated with a higher ratio of urinary Ang II to Ang-(1-7) (β: 0.21, 95% CI -0.02 to 0.44), an effect that approached statistical significance. CONCLUSIONS Among preterm-born adolescents, overweight/obesity was associated with increased Ang II but reduced Ang-(1-7) in the circulation and the kidney as well as higher blood pressure. Obesity may compound the increased risk of hypertension and cardiovascular disease in individuals born prematurely by further augmenting the prematurity-associated imbalance in the renin-angiotensin system.

Abstract
BACKGROUND Preterm birth increases the risk of hypertension and kidney disease. However, it is unclear when changes in blood pressure (BP) and renal function become apparent and what role obesity and sex play. We hypothesized adolescents born preterm have higher BP and worse kidney function compared to term in an obesity- and sex-dependent manner. METHODS Cross-sectional analysis of 14-year-olds born preterm with very low birth weight (n = 96) compared to term (n = 43). We used generalized linear models to estimate the associations among preterm birth and BP, estimated glomerular filtration rate (eGFR), and ln (x) urinary albumin-to-creatinine ratio (ACR), stratified by overweight/obesity (OWO, body mass index (BMI) ≥ 85th percentile) and sex. RESULTS Compared to term, preterm-born adolescents had higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) (adjusted β (aβ) 3.5 mmHg, 95% CI - 0.1 to 7.2 and 3.6 mmHg, 95% CI 0.1 to 7.0), lower eGFR (β - 8.2 mL/min/1.73 m2, 95% CI - 15.9 to - 0.4), and higher ACR (aβ 0.34, 95% CI - 0.04 to 0.72). OWO modified the preterm-term difference in DBP (BMI < 85th percentile aβ 5.0 mmHg, 95% CI 0.7 to 9.2 vs. OWO 0.2 mmHg, 95% CI - 5.3 to 5.6) and ACR (OWO aβ 0.72, 95% CI 0.15 to 1.29 vs. BMI < 85th percentile 0.17, 95% CI - 0.31 to 0.65). Sex modified the preterm-term ACR difference (female aβ 0.52, 95% CI 0.001 to 1.04 vs. male 0.18, 95% CI - 0.36 to 0.72). CONCLUSIONS Prematurity was associated with higher BP and reduced renal function that were detectable in adolescence. OWO and sex may modify the strength of these relationships.

Abstract
BACKGROUND Survival of preterm neonates has steadily improved over the past five decades, due to changes in the neonatal intensive care. However, in Saudi Arabia, there are no written guidelines on the definition of the lower limit of viability, and there has been a call for such a limit. The aims of this study were: (1) to determine lower limits of viability and survival in extremely low birthweight (ELBW) infants, and (2) to determine incidence of neurodevelopmental and cognitive abnormalities within 3-6 years after birth. METHODS Prospective study of all live inborn ELBW infants admitted to the neonatal unit of King Abdulaziz Medical City, Riyadh, Saudi Arabia, within 3 years [between January 1st, 2005 and December 31st, 2007] was conducted (n = 117). Data were collected on demographic and birth data, neonatal complications & interventions and death on discharge. Prospective follow up of all survivors was done, within 6 years after birth, to assess the outcome in terms of neurodevelopmental and cognitive abnormalities. Predictors of survival were determined using logistic regression model. Significance was considered at p-value ≤0.05. RESULTS Of all ELBW infants, 41% died before discharge. Survival rate was directly correlated with gestational age (GA) and birthweight (p < 0.05). The 50% limits of viability were those at 25 weeks' gestation or with > 600 g. After adjusting for possible confounders, significant predictors of survival were birthweight (p = 0.001) and Apgar score (p < 0.001). The following impairments were reported during follow up of survivors: developmental delay (39.2%), cerebral palsy (36.2%), speech problems (33.3%), wasting (12.5%), intellectual disability (10%), visual problems (6.6%) and hyperactivity (5.6%). CONCLUSION More than one-third of ELBW died before discharge from NICU, and two-thirds of survivors had one or more neurodevelopmental and/or cognitive abnormalities during their first 6 years of life. The 50% limits of viability of ELBW infants were those at week 25 of gestation or with a birthweight of more than 600 g. Birthweight could be considered as more valid than gestational age in the prediction of viability of ELBW infants. The process of care of ELBW infants in Saudi Arabia may need to be revisited taking these findings into consideration.

Abstract
BACKGROUND Ventilator-induced lung injury with subsequent bronchopulmonary dysplasia remains an important issue in the care of extremely low-birth-weight infants. Permissive hypercapnia has been proposed to reduce lung injury. Hypercapnia changes cerebral perfusion, but its influence on the peripheral microcirculation is unknown. METHODS Data were collected from 12 infants, who were randomized to a permissive high PCO2 target group (HTG) or a control group (CG). Inclusion criteria were birth weight between 400 and 1,000 g, gestational age from 23 to 28 6/7 weeks, intubation during the first 24 h of life, and no malformations. The PCO2 target range was increased stepwise in both groups for weaning and was always 15 mmHg higher in the HTG than in the CG. Skin microvascular parameters were assessed non-invasively with sidestream dark field imaging on the inner side of the right arm every 24 h during the first week of life and on the 14th day of life. RESULTS Infants in the HTG had significantly higher max. PCO2 exposure, which was associated with a significantly and progressively reduced functional vessel density (FVD, p < 0.01). Moreover, there were significant differences in the diameter distribution over time, with HTG subjects having fewer small vessels but more large vessels. CONCLUSION High PCO2 levels significantly impaired peripheral microcirculation in preterm infants, as shown by a decreased FVD, presumably secondary to peripheral vasoconstriction. ISRCTN 56143743.

The Medical Home at 50: Are Children With Medical Complexity the Key to Proving Its Value? Acad Pediatr 2017; 17:581-588. [PMID: 28457939 DOI: 10.1016/j.acap.2017.04.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2016] [Revised: 04/09/2017] [Accepted: 04/09/2017] [Indexed: 11/21/2022]
Abstract
The medical home has been widely promoted as a model of primary care with the potential to transform the health care delivery system. Although this model was initially focused on children with chronic conditions, the American Academy of Pediatrics has endorsed a generalization of the model, promoting the statement, "Every child deserves a medical home." Recently, other major professional and governmental organizations have embraced this more inclusive vision, and the medical home concept has been promoted in provisions of the Affordable Care Act. Yet, rigorous evaluations of the value of the medical home, within pediatrics and beyond, have been limited, and the results have been mixed. Early results from large demonstration projects in adults have generally noted modest improvements in quality without accompanying reductions in cost. At this critical period in health care, with widespread interest in health care delivery and payment reform, these results present a potential threat to the medical home. Understanding possible reasons for these early findings is crucial to sustaining the spread of the medical home beyond its first 50 years. With this aim, we review the history of the medical home and trends in child health, and we explore the concepts of value and complexity as they pertain to pediatric health care delivery. We propose that, because of the demographic characteristics and economics of child health and current policy imperatives with regard to health care, a strong value proposition for the medical home in pediatrics involves children with medical complexity.

Abstract
BACKGROUND Patent ductus arteriosus (PDA) is a common problem in the preterm infants. The frequency of PDA varies with the time of study, and the characteristics of the population included in the trial. AIMS AND OBJECTIVE To determine the prevalence and prenatal risk factor associated with PDA. METHODS AND MATERIAL This prospective cross-sectional observational study was carried out on neonates who had gestational age below 37 weeks during the period of February 2014 to September 2014. Echocardiography was done at 4-7 days of postnatal age. The association between prenatal risk factors of the infants and the PDA was studied. RESULTS From a total population of 200 enrolled infants 22.5% had PDA. The mean gestational age and birth weight were 32.1 ± 2.65 (weeks) and 1741 ± 622.85 (g), respectively. Maternal antepartum hemorrhage, respiratory distress syndrome (RDS), need for surfactant, birth weights, female gender, gestational age, Apgar scores at 1 and 5 min of the infants were found to be associated with the prevalence of PDA. CONCLUSION Several prenatal factors make preterm newborns susceptible to PDA. These risk factors should be identified as soon as possible for early commencement of PDA management.

Medical foster care: what happens when children with medical complexity cannot be cared for by their families? Pediatr Res 2016; 79:191-6.

Abstract
Medical interventions for life-threatening pediatric conditions often oblige ongoing and complex medical care for survivors. For some children with medical complexity, their caretaking needs outstrip their parents' resources and abilities. When this occurs, the medical foster care system can provide the necessary health care and supervision to permit these children to live outside of hospitals. However, foster children with medical complexity experience extremes of social and medical risk, confounding their prognosis and quality of life beyond that of similar children living with biologic parents. Medical foster parents report inadequate training and preparation, perpetuating these health risks. Further, critical decisions that weigh the benefits and burdens of medical interventions for these children must accommodate complicated relationships involving foster families, caseworkers, biologic families, legal consultants, and clinicians. These variables can delay and undermine coordinated and comprehensive care. To rectify these issues, medical homes and written care plans can promote collaboration between providers, families, and agencies. Pediatricians should receive specialized training to meet the unique needs of this population. National policy and research agendas could target medical and social interventions to reduce the need for medical foster care for children with medical complexity, and to improve its quality for those children who do.

Abstract
BACKGROUND Many previous studies that have investigated hospital admissions in children and young people with cerebral palsy lack information on cerebral palsy severity and complexity. Consequently, little is known about factors associated with the frequency and type of hospital admissions in this population. This study used hospital admission data available for all children and young people known to a population-based cerebral palsy register to describe the patterns of use of tertiary paediatric hospital services over a 5-year period. METHODS This was a retrospective cohort analysis of routinely collected admission data from the two tertiary paediatric hospitals in the Australian state of Victoria. Data on admissions of individuals born between 1993 and 2008 registered on the Victorian Cerebral Palsy Register were analysed (n = 2183). RESULTS Between 2008 and 2012, 53% of the cohort (n = 1160) had at least one same-day admission, and 46% (n = 996) had one or more multi-day admissions. Those with a moderate to severe motor impairment and those with a co-diagnosis of epilepsy had more admissions, and for multi-day admissions, longer lengths of stay, P < 0.05. Across all severity levels, respiratory and musculoskeletal diseases were the most frequently reported reasons for medical and surgical admissions, respectively. All-cause readmission rates for urgent multi-day stays within 7, 30 and 365 days of an index admission were 10%, 23% and 63%, respectively. CONCLUSIONS The reasons for hospital admissions reported here reflect the range of comorbidities experienced by children and young people with cerebral palsy. This study highlights priority areas for prevention, early diagnosis and medical management in this group. Improved primary and secondary prevention measures may decrease non-elective hospital admissions and readmissions in this group and reduce paediatric inpatient resource use and healthcare expenditure attributable to cerebral palsy.

Abstract
OBJECTIVES Children with complex chronic conditions (CCC) are responsible for a disproportionate number of hospital readmissions. This study sought to determine 30-day hospital readmission rates in children with CCC discharged from a rehabilitation and transitional care hospital and to identify factors associated with increased risk of readmission. METHODS We conducted a retrospective cohort study identifying children with CCC discharged over an 18-month period from a subacute care facility staffed by hospitalists from a freestanding children's hospital. The primary outcome measure was readmission to the referring acute care hospital within 30 days of the subacute discharge. RESULTS Of the 272 discharged patients meeting inclusion criteria as children with at least 1 CCC, 19% had at least 1 readmission within 30 days of discharge. On univariate analysis, readmission was associated with the number of home medications (P = .001), underlying chronic respiratory illness (P < .001), home apnea or pulse oximetry monitor use (P = .02), tracheostomy and/or ventilator dependence (P = .003), length of stay (P = .04), and number of follow-up appointments (P = .02). On multivariate analysis, the number of discharge medications was associated with increased odds of readmission (odds ratio: 1.11 [95% confidence interval: 1.03-1.20]; P = .01). Receiver operating curve analysis identified a cutoff of 8 medications as most associated with readmission; in patients discharged with ≥8 medications, the hospital readmission rate was 29%. CONCLUSIONS This is the first known study that investigated hospital readmission rates in children with CCC discharged from a subacute facility and specifically identified the number of discharge medications as a significant risk factor for readmission.

Abstract
The term "viability" is not simply a synonymous with being "born alive," but is closely related to the capability of having a "meaningful life" and having a reasonable period of survival. The definition of "viability" is generally based on two major criteria: the biological, which takes into consideration the maturity of the foetus, and the epidemiological, which is based on the survival rates reported in literature. The neuromaturation of the cerebral cortex is a dynamic process promoted by the subplate, a transient population of neurons that guides the development of cortical and thalamocortical connections. These connections are for example fundamental for cortical processing of sensory information and mental processes. The first thalamocortical and cortico-cortical connections grows at 23-24 postconceptional weeks, which coincides with the age limit for premature baby survival.

Abstract
One of the most notable trends in child health has been the increase in the number of children with special health care needs, including those with complex chronic conditions. Care of these children accounts for a growing fraction of health care resources. We examine recent developments in health care, especially with regard to medical transport and prehospital care, that have emerged to adapt to this remarkable demographic trend. One such development is the focus on care coordination, including the dissemination of the patient-centered medical home concept. In the prehospital setting, the need for greater coordination has catalyzed the development of the emergency information form. Training programs for prehospital providers now incorporate specific modules for children with complex conditions. Another notable trend is the shift to a family-centered model of care. We explore efforts toward regionalization of care, including the development of specialized pediatric transport teams, and conclude with recommendations for a research agenda.

Abstract
OBJECTIVE In this study we used national data to determine changes in the prevalence of hospital admissions for medically complex children over a 15-year period. PATIENTS AND METHODS Data from the Nationwide Inpatient Sample, a component of the Healthcare Cost and Utilization Project, was analyzed in 3-year increments from 1991 to 2005 to determine national trends in rates of hospitalization of children aged 8 days to 4 years with chronic conditions. Discharge diagnoses from the Nationwide Inpatient Sample were grouped into 9 categories of complex chronic conditions (CCCs). Hospitalization rates for each of the 9 CCC categories were studied both individually and in combination. Trends of children hospitalized with 2 specific disorders, cerebral palsy (CP) and bronchopulmonary dysplasia, with additional diagnoses in more than 1 CCC category were also examined. RESULTS Hospitalization rates of children with diagnoses in more than 1 CCC category increased from 83.7 per 100,000 (1991-1993) to 166 per 100 000 (2003-2005) (P[r]<.001). The hospitalization rate of children with CP plus more than 1 CCC diagnosis increased from 7.1 to 10.4 per 100 000 (P=.002), whereas the hospitalization rates of children with bronchopulmonary dysplasia plus more than 1 CCC diagnosis increased from 9.8 to 23.9 per 100,000 (P<.001). CONCLUSIONS Consistent increases in hospitalization rates were noted among children with diagnoses in multiple CCC categories, whereas hospitalization rates of children with CP alone have remained stable. The relative medical complexity of hospitalized pediatric patients has increased over the past 15 years.

Abstract
BACKGROUND Audit of disease and mortality patterns provides essential information for health budgeting and planning, as well as a benchmark for comparison. Neonatal mortality accounts for about 1/3 of deaths < 5 years of age and very low birth weight (VLBW) mortality for approximately 1/3 of neonatal mortality. Intervention programs must be based on reliable statistics applicable to the local setting; First World data cannot be used in a Third World setting. Many neonatal units participate in the Vermont Oxford Network (VON); limited resources prevent a significant number of large neonatal units from developing countries taking part, hence data from such units is lacking. The purpose of this study was to provide reliable, recent statistics relevant to a developing African country, useful for guiding neonatal interventions in that setting. METHODS This was a retrospective chart review of 474 VLBW infants admitted within 24 hours of birth, between 1 July 2006 and 30 June 2007, to the neonatal unit of Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) in Johannesburg, South Africa. Binary outcome logistic regression on individual variables and multiple logistic regression was done to identify those factors determining survival. RESULTS Overall survival was 70.5%. Survival of infants below 1001 grams birth weight was 34.9% compared to 85.8% for those between 1001 and 1500 grams at birth. The main determinant of survival was birth weight with an adjusted survival odds ratio of 23.44 (95% CI: 11.22 - 49.00) for babies weighing between 1001 and 1500 grams compared to those weighing below 1001 grams. Other predictors of survival were gender (OR 3. 21; 95% CI 1.6 - 6.3), birth before arrival at the hospital (BBA) (OR 0.23; 95% CI: 0.08 - 0.69), necrotising enterocolitis (NEC) (OR 0.06; 95% CI: 0.02 - 0.20), hypotension (OR 0.05; 95% CI 0.01 - 0.21) and nasal continuous positive airways pressure (NCPAP) (OR 4.58; 95% CI 1.58 - 13.31). CONCLUSIONS Survival rates compare favourably with other developing countries, but can be improved; especially in infants < 1001 grams birth weight. Resources need to be allocated to preventing the birth of VLBW babies outside hospital, early neonatal resuscitation, provision of NCPAP and prevention of NEC.

Abstract
OBJECTIVE Permissive hypercapnia is a respiratory-care strategy that is used to reduce the risk for lung injury. The goal of this study was to evaluate whether permissive hypercapnia is associated with higher risk for intraventricular hemorrhage and early childhood behavioral and functional problems than normocapnia among very low birth weight infants. METHODS Very low birth weight infants from a statewide cohort were eligible for this study when they were born at <32 weeks' gestational age and survived at least 24 hours. Infants were classified as receiving a permissive hypercapnia, normocapnia, or unclassifiable respiratory strategy during the first 24 hours after birth according to an algorithm based on Pco(2) values and respiratory-treatment decisions that were abstracted from medical charts. Intraventricular hemorrhage diagnosis was also abstracted from the medical chart. Behavioral and functional outcomes were assessed by parent interview at 2 to 3 years. Logistic regression was used to evaluate the relationship between intraventricular hemorrhage and respiratory strategy; ordinary linear regression was used to evaluate differences in behavior and function scores between children by respiratory strategy. RESULTS Infants who received a permissive hypercapnia strategy were not more likely to have intraventricular hemorrhage than those with normocapnia. There were no differences in any of the behavioral or functional scores among children according to respiratory strategy. There was a significant interaction between care strategy and 1-minute Apgar score, indicating that infants with lower Apgar scores may be at higher risk for intraventricular hemorrhage with permissive hypercapnia. CONCLUSIONS This study suggests that permissive hypercapnia does not increase risk for brain injury and impairment among very low birth weight children. The interaction between respiratory strategy and Apgar score is a potential worrisome exception to this conclusion. Future research should further evaluate the effect of elevated Pco(2) levels among those who are sickest at birth.

Abstract
INTRODUCTION As survival and long-term morbidity of very preterm infants have improved over the past decade, the limits of infant viability, the level of maturity below which survival and/or acceptable neurodevelopmental outcome are extremely unlikely, have also decreased. STUDY DESIGN In an effort to define the current limits of infant viability, the data in the literature on survival and long-term neurodevelopmental outcome in very preterm neonates have been reviewed. RESULT The gestational age and birth weight below which infants are too immature to survive, and thus provision of intensive care is unreasonable, appears to be at <23 weeks and <500 g, respectively. Infants born at > or =25 weeks' gestation and with a birth weight of > or =600 g are mature enough to warrant initiation of intensive care, as the majority of these patients survive, and at least 50% do so without severe long-term disabilities. Finally, for infants born between 23(0/7) and 24(6/7) weeks' gestation and with a birth weight of 500 to 599 g, survival and outcome are extremely uncertain. For these infants born in the so-called 'gray zone' of infant viability, the line between patient autonomy and medical futility is blurred, and medical decision-making becomes even more complex and needs to embrace careful consideration of several factors. These factors include appraisal of prenatal data and the information obtained during consultations with the parents before delivery; evaluation of the patient's gestational age, birth weight and clinical condition upon delivery; ongoing reassessment of the patient's response to resuscitation and intensive care and continued involvement of the parents in the decision-making process after delivery. CONCLUSION Based on these findings an algorithm is offered for consideration for neonatologists managing infants born in the 'gray zone' of infant viability. However, caution must be exercised when one considers incorporating this guideline into clinical practice because the algorithm is based on the analysis of the findings in the literature and the authors' experience rather than direct evidence.

Abstract
Children born with very low birth weight (VLBW) are at risk of impaired growth. We aimed to study VLBW survivors (90.8%) born in 1998/1999 in the state of Baden-Württemberg (n = 2103) for whom growth data were available up to age six. Classification as appropriate for gestational age (AGA) or small for gestational age (SGA) depended on size at birth. Models to predict height SDS at 5 y were developed using data for 1 yr (Model 1) and 2 yrs (Model 2). The data of 1320 (63%) children were available: SGA: n = 730, AGA: n = 590. At 6 yrs, 8.3% AGA and 13.4% SGA children were short (<-2.0 SDS). The following factors explained Ht SDS at 5 (and 6) yrs (order of importance): (a) Model 1 (n = 1033; R2 = 0.52; error: 0.84 SDS): 1st yr Ht SDS, mid-parental height (MPH) SDS, 1 yr weight SDS, birth weight SDS; (b) Model 2 (n = 991; R2 = 0.72; error: 0.65 SDS): 1st yr Ht SDS; change (2nd yr) in Ht and weight SDS; MPH SDS; 1st yr weight SDS; birth weight SDS. Thus, some AGA and SGA children born VLBW remain short and preventive strategies need to be developed for those at risk.

Abstract
Vascular smooth muscle (VSM) maturation is developmentally regulated and differs between vascular beds. The maturation and contribution of VSM function to tissue blood flow and blood pressure regulation during early gestation are unknown. The carotid artery (CA) contributes to fetal cerebral blood flow regulation and well being. We studied CA VSM contractility, protein contents, and phenotype beginning in the midthird of ovine development. CAs were collected from early (88-101 day of gestation) and late (138-150 day; term = day 150) fetal (n = 14), newborn (6-8 day old; n = 7), and adult (n = 5) sheep to measure forces in endothelium-denuded rings with KCl, phenylephrine, and ANG II; changes in cellular proteins, including total and soluble protein, actin and myosin, myosin heavy chain isoforms (MHC), filamin, and proliferating cell nuclear antigen; and vascular remodeling. KCl and phenylephrine elicited age- and dose-dependent contraction responses (P < 0.001) at all ages except early fetal, which were unresponsive. In contrast, ANG II elicited dose responses only in adults, with contractility increasing greater than fivefold vs. that shown in fetal or neonatal animals (P < 0.001). Increased contractility paralleled age-dependent increases (P < 0.01) in soluble protein, actin and myosin, filamin, adult smooth muscle MHC-2 (SM2) and medial wall thickness and reciprocal decreases (P < 0.001) in nonmuscle MHC-B, proliferating cell nuclear antigen and medial cellular density. VSM nonreceptor- and receptor-mediated contractions are absent or markedly attenuated in midgestation and increase age dependently, paralleling the transition from synthetic to contractile VSM phenotype and, in the case of ANG II, paralleling the switch to the AT(1) receptor. The mechanisms regulating VSM maturation and thus blood pressure and tissue perfusion in early development remain to be determined.

Abstract
BACKGROUND/PURPOSE The management of intestinal perforation in very low birth weight (VLBW) infants (less than 1500 g) is controversial. Current practice favors peritoneal drainage (PD) with or without a delayed laparotomy over primary laparotomy (PL). We compared the outcomes of PD +/- delayed laparotomy vs PL in VLBW infants using the Score for Neonatal Acute Physiology with Perinatal Extension (SNAPPE-II) as a validated predictor of mortality. METHODS A retrospective analysis (1998-2003) of VLBW infants with intestinal perforation at 2 pediatric centers was undertaken. Data retrieval included neonatal demographics and parameters for SNAPPE-II calculation. The primary end point was 30-day mortality. Other outcome measures included in-hospital mortality, days fasting, days to extubation, and length of stay. Statistical analysis was performed with either Student's t test or chi2 analysis. Subgroup and multivariate analyses were also performed. P values < .05 were considered significant. RESULTS Fifty-two neonates (25 PD, 27 PL) were reviewed. Overall, 10 (19.2%) infants died. Observed 30-day mortality rates in PD and PL groups were 32% and 7.4% (P = .028), respectively. Average SNAPPE-II scores for PD (42.5 +/- 20.8) and PL (25.1 +/- 14.6) groups yielded predicted mortality rates of 15.7% and 4.9% (P = .001), respectively. PD group 30-day mortality far exceeded the rate predicted by the SNAPPE-II score. Days fasting (13.7 vs 20.4; P = .0001), days to extubation (26.7 vs 51.5; P = .014), and length of stay (56.1 vs 83.6; P = .031) all favored the PL group despite incorporating SNAPPE-II score as a covariate into the multivariate analysis. Of the 25 patients receiving drainage, 9 underwent PD alone (SNAPPE-II = 46.6 +/- 27.9), whereas 16 patients underwent delayed laparotomy (SNAPPE-II = 37.8 +/- 17.6). The PD-only group had a greatly elevated mortality rate (77.8% vs 15.7% predicted), whereas the delayed laparotomy group had a reduced mortality rate (6.3% vs 9.3% predicted). CONCLUSION Our data suggest that laparotomy, either alone or after PD, provides an improved outcome in VLBW infants with intestinal perforation. PD should be used as a temporizing measure until laparotomy can be performed.

Abstract
OBJECTIVE To evaluate the antenatal profile of the mother and the immediate neonatal morbidity and mortality till discharge. METHODS The study was a retrospective analysis of 92 patients of preterm labour who delivered babies weighing RESULTS A total of 92 mothers in preterm labour at 26 to 34 weeks were admitted and subsequently delivered 70 VLBW babies (< 1500 gms) and 36 ELBW babies (< 1000 gms) including 8 pairs of twins and 3 triplets pregnancies. Majority of the patients (93.4%) were booked. Amongst the various high risk factors for preterm labour, anaemia during pregnancy (32.6%), bacterial vaginosis (26%), gestational hypertension (18.4%) and pervious history of preterm labour (18.4%) were common associations. Calcium channel blocker (Depin) tocolysis was effective in postponing labour from 48 hours to more than 2 weeks. The cesarean section rate was very high (67.3%) in our study. The commoner neonatal complications in both VLBW and ELBW babies were RDS, neonatal jaundice and sepsis. Features of IUGR were seen in both the groups (22.8% in VLBW and 22.2% in ELBW babies). The neonatal mortality rate till discharge was 15.7% in VLBW group and 33.3% in ELBW group. The morality rate was highest in 26 to 30 weeks gestation babies and in babies weighing < 800 gms. CONCLUSION Antenatal profile of preterm labour in our series showed a number of high risk factors. The identification of common high risk factors is important for appropriate prenatal care. A better neonatal survival rate was possible due to timely intervention, appropriate management and NICU care facility available in our tertiary care centre.

Abstract
OBJECTIVE Ductus arteriosus (DA) closure occurs within 96 hours in >95% of neonates >1500 g in birth weight (BW). The prevalence and postnatal age of spontaneous ductal closure in neonates < or =1000 g in BW (extremely low birth weight [ELBW] neonates) remain unclear, as does the incidence of failure to close with indomethacin. Therefore, we prospectively examined the prevalence, postnatal age, and clinical variables associated with spontaneous DA closure, occurrence of persistent patent DA, and indomethacin failure in ELBW neonates. METHODS Neonates delivered at Parkland Memorial Hospital from February 2001 through December 2003 were studied. Those with congenital heart defects or death <10 days postnatally were excluded. Echocardiograms were performed 48 to 72 hours postnatal and every 48 hours until 10 days postnatally. RESULTS We studied 122 neonates with BW of 794 +/- 118 (SD) g and estimated gestational age (EGA) of 26 +/- 2 weeks. Spontaneous permanent DA closure occurred in 42 (34%) neonates at 4.3 +/- 2 days postnatally, with 100% closure by 8 days. These neonates were more mature, less likely to have received antenatal steroids or have hyaline membrane disease (HMD; 52% vs 79%), and more likely to be growth restricted (31% vs 5%) and delivered of hypertensive women. Using regression analysis, EGA and absence of antenatal steroids and HMD predicted ductal closure. Ten (8%) neonates with early DA closure reopened and required medical/surgical closure. Eighty neonates had persistent patent DA; 7 were surgically ligated, and 5 remained asymptomatic, with 4 of 5 closing after 10 days postnatally. Sixty-eight (85%) received indomethacin at 6.2 +/- 4 days postnatally; 41% failed therapy and had no distinguishing characteristics. CONCLUSIONS Spontaneous permanent DA closure occurs in >34% of ELBW neonates and is predicted by variables related to maturation, for example, EGA and an absence of HMD, whereas indomethacin failure could not be predicated.

Abstract
Background Recent reports have documented a leveling-off of survival rates in preterm infants through the 1990's. The objective of this study was to determine temporal changes in illness severity in very low birth weight (VLBW) infants in relationship to the outcomes of death and/or severe IVH. Methods Cohort study of 1414 VLBW infants cared for in a single level III neonatal intensive care unit in Delaware from 1993–2002. Infants were divided into consecutive 3-year cohorts. Illness severity was measured by two objective methods: the Score for Neonatal Acute Physiology (SNAP), based on data from the 1st day of life, and total thyroxine (T4), measured on the 5th day of life. Death before hospital discharge and severe intraventricular hemorrhage (IVH) were investigated in the study sample in relation to illness severity. The fetal death rate was also investigated. Statistical analyses included both univariate and multivariate analysis. Results Illness severity, as measured by SNAP and T4, increased steadily over the 9-year study period with an associated increase in severe IVH and the combined outcome of death and/or severe IVH. During the final 3 years of the study, the observed increase in illness severity accounted for 86% (95% CI 57–116%) of the variability in the increase in death and/or severe IVH. The fetal death rate dropped from 7.8/1000 (1993–1996) to 5.3/1000 (1999–2002, p = .01) over the course of the study. Conclusion These data demonstrate a progressive increase in illness in VLBW infants over time, associated with an increase in death and/or severe IVH. We speculate that the observed decrease in fetal death, and the increase in neonatal illness, mortality and/or severe IVH over time represent a shift of severely compromised patients that now survive the fetal time period and are presented for care in the neonatal unit.

Abstract
OBJECTIVE This study examines the incidence, utilization of procedures, and outcomes for critically ill children hospitalized with traumatic brain injury over the period 1988-1999 to describe the benefits of improved treatment. DESIGN Retrospective analysis of hospital discharges was conducted using data from the Health Care Cost and Utilization Project Nationwide Inpatient Sample that approximates a 20% sample of U.S. acute care hospitals. SETTING Hospital inpatient stays from all types of U.S. community hospitals. PARTICIPANTS The study sample included all children aged 0-21 with a primary or secondary ICD-9-CM diagnosis code for traumatic brain injury and a procedure code for either endotracheal intubation or mechanical ventilation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Deaths occurring during hospitalization were used to calculate mortality rates. Use of intracranial pressure monitoring and surgical openings of the skull were investigated as markers for the aggressiveness of treatment. Patients were further classified by insurance status, household income, and hospital characteristics. Over the 12-yr study period, mortality rates decreased 8 percentage points whereas utilization of intracranial pressure monitoring increased by 11 percentage points. The trend toward more aggressive management of traumatic brain injury corresponded with improved hospital outcomes over time. Lack of insurance was associated with vastly worse outcomes. An estimated 6,437 children survived their traumatic brain injury hospitalization because of improved treatment, and 1,418 children died because of increased mortality risk associated with being uninsured. Improved treatment was valued at approximately dollar 17 billion, whereas acute care hospitalization costs increased by dollar 1.5 billion (in constant 2000 dollars). Increased mortality in uninsured children was associated with a dollar 3.76 billion loss in economic benefits. CONCLUSIONS More aggressive management of pediatric traumatic brain injury appears to have contributed to reduced mortality rates over time and saved thousands of lives. Additional lives could be saved if mortality rates could be equalized between insured and uninsured children.

Abstract
PROBLEM Clinical care of infants with a very low birth weight (less than 1500 g) in developing countries can be labour intensive and is often associated with a prolonged stay in hospital. The Aga Khan University Medical Center in Karachi, Pakistan, established a neonatal intensive care unit in 1987. By 1993-4, very low birthweight infants remained in hospital for 18-21 days. STRATEGIES FOR CHANGE A stepdown unit was established in September 1994, with mothers providing all basic nursing care for their infants before being discharged under supervision. KEY MEASURES FOR IMPROVEMENT We analysed neonatal outcomes for the time periods before and after the stepdown unit was created (1987-94 and 1995-2001). We compared these two time periods for survival after birth until discharge, morbidity patterns during hospitalisation, length of stay in hospital, and readmission rates to hospital in the four weeks after discharge. EFFECTS OF CHANGE Of 509 consecutive, very low birthweight infants, 494 (97%) preterm and 140 (28%) weighing < 1000 g at birth), 391 (76%) survived to discharge from the hospital. The length of hospitalisation fell significantly from 1987-90, when it was 34 (SD 18) days, to 16 (SD 14) days in 1999-2001 (P < 0.001). Readmission rates to hospital did not rise, nor did adverse outcomes at 12 months of age. LESSONS LEARNT Our results indicate that it is possible to involve mothers in the active care of their very low birthweight infants before discharge. This may translate into earlier discharge from hospital to home settings without any increase in short term complications and readmissions.
