Differences in growth patterns and catch up growth of small for gestational age preterm infants fed on fortified mother's own milk versus preterm formula.

Small for gestational age (SGA) is typically defined as birthweight < 10th percentile for age. Limited data are available regarding the growth of SGA preterm infants in relation to feeding type. We aimed to study SGA preterm infants fed fortified mother's own milk (MOM) or preterm formula (PF) on growth patterns and catch-up growth at discharge and two-years corrected age (CA). Our retrospective cohort study included data from medical records and follow-up questionnaires about SGA preterm infants born at <37 weeks fed on MOM (n=40) and PF (n=40). Weight, length/height and head circumference (HC) were collected at birth, discharge and at two years CA, and Δ z-scores were calculated.The MOM group had significantly larger negative change in weight and length z-scores between birth and discharge, and smaller positive change in HC z-score (-0.47 (±0.41) v. -0.25 (±0.36), P= 0.01; -0.63 (±0.75) v. -0.27 (±0.75), P= 0.03; 0.13 (±0.67) v. 0.41 (±0.55), P= 0.04, respectively). Almost half the MOM fed infants experienced poor length growth by discharge compared to 22% of PF fed infants (P=0.03). By two years CA, both groups had similar positive change in weight and HC z-scores, but MOM fed infants had a slower increase in height z-score (0.64 (±1.30) v. 1.33 (±1.33), P=0.02), and only 40% had achieved catch-up height compared with 68% of the PF group (P=0.02).Our study indicates that fortified MOM fed SGA preterm infants may need extra nutritional support in the first two years of life to achieve height growth potential.

Third-generation cephalosporin resistant Enterobacteriaceae in neonates and young infants: impact and outcome.

OBJECTIVE: Third-generation cephalosporins resistant Enterobacteriaceae (3GCR-EB) are a major threat in severely ill neonates hospitalized in Neonatal Intensive Care Units. Still, the particular impact of 3GCR-EB on outcomes in the wide neonatal population is not well-appreciated. We aimed to study the impact of 3GCR-EB on the length of hospital stay and mortality of a general population of neonates and young infants. STUDY DESIGN: This was a retrospective cohort study of neonates and young infants born in eight Israeli hospitals between 2009 and 2013, with a culture taken within three months after birth that tested positive for Enterobacteriaceae (EB). Data for this study were taken from centralized electronic health records included inpatient, outpatient, socio-demographic, administrative and laboratory information. The main outcomes were length of stay and mortality. The main explanatory variable was an isolation of 3GCR-EB in any bacterial culture taken from a neonate or young infant. RESULTS: Cultures were taken for 31,921 neonates and young infants; 2647 (8.3%) tested positive for EB and 290 (11%) tested positive for 3GCR-EB. Length of stay for those who tested positive was 2.8 times longer (95%CI: 2.70-2.91, p ˂ .001) than patients who tested positive for 3GC-susceptible EB. 3GCR-EB were also associated with increased mortality (OR: 12.06, 95%CI: 4.92-32.29). CONCLUSIONS: Neonates with third-generation cephalosporins resistant Enterobacteriaceae had extended hospitalization and increased mortality, which was mostly significant in normal gestational weight newborns.

Centers for disease control and prevention guidelines identified more neonates at risk of early-onset sepsis than the Kaiser-Permanente calculator.

AIM: Our aim was to retrospectively compare how many cases of early-onset sepsis (EOS) would have been predicted by the the Kaiser-Permanente (KP) calculator and the United States Centers for Disease Control and Prevention (CDC) guidelines. METHODS: This observational retrospective cohort study comprised 50 newborn infants with documented EOS who were born at the Kaplan Medical Centre, Israel, between 2001 and 2018. We retrospectively evaluated whether the KP calculator and the CDC recommendations would have recommended antibiotic treatment if they had been implemented within four hours of birth. RESULTS: EOS was diagnosed in 50 of the 109 877 infants born from 34 weeks of gestation. By four hours of birth, 18 were symptomatic, five had an equivocal clinical status, and 27 were asymptomatic. The KP calculator would have recommended antibiotic treatment for 19 (38%) neonates: 18 who were symptomatic and one who was initially asymptomatic. The CDC guidelines would have recommended antibiotic treatment for 27 (54%) nenonates: those 19 plus all 5 with equivocal status and other 3 who were asymptomatic. CONCLUSION: Using the CDC guidelines would have identified more equivocal and asymptomatic EOS cases within four hours of birth than the KP calculator. Enhanced observation is recommended when using the KP calculator.

Antenatal corticosteroid therapy is associated with a lower risk of cystic periventricular leukomalacia.

AIM: To evaluate the association of antenatal corticosteroids (ACS) therapy on the risk for cystic periventricular leukomalacia (c-PVL) in very low birth weight (VLBW), very preterm infants, whilst accounting for the occurrence of major neonatal morbidities; sepsis, necrotising enterocolitis, intraventricular haemorrhage and bronchopulmonary dysplasia. METHODS: Population-based observational cohort study applying data collected by the Israel national VLBW infant database from 1995-2016. RESULTS: Cystic PVL was diagnosed in 692 (6.8%) of the 10,170 study infants. Among 7522 infants exposed to ACS, the rate of c-PVL was 5.4%, compared to 10.7% among those not exposed (p < 0.0001). ACS was associated with significantly lower odds for c-PVL (Odds Ratio [OR] 0.69, 95% confidence interval [CI] 0.57-0.84). In subgroup analyses, excluding infants with one or more morbidities the rates of c-PVL ranged from 2.7% to 5.4% among infants exposed to ACS compared to 5.6% to 10.7% in those not exposed (all p < 0.0001). ACS was associated with significantly lower OR's for c-PVL in all subgroups, ranging from 0.52 (95% CI 0.40-0.66) to 0.62 (95% CI 0.50-0.77). CONCLUSION: Infants exposed to ACS had a significantly lower risk of c-PVL. Subgroup analyses excluding infants with major neonatal comorbidities showed a consistent reduction of 40%-50% in the risk for c-PVL following ACS therapy.

Not all newborns born to mothers with clinical chorioamnionitis need to be treated.

PURPOSE: The 2010 recommendations of the Centers for Disease Control and Prevention (CDC) for prevention of perinatal group B Streptococcal Disease (GBS) is that symptomatic newborns suspect for early onset sepsis (EOS), or newborns born to mothers with clinical chorioamnionitis should receive antibiotic treatment. Our protocol was changed accordingly during 2015. We prospectively assessed the safety of the protocol and evaluated the need to treat all newborns born to mothers with clinical chorioamnionitis and retrospectively evaluated the performance of the EOS risk calculator. METHODS: The study period was from May 2015 to April 2016 at the Kaplan Medical Center (KMC). Inclusion criteria were: gestational age of 35 weeks and above, newborns that were treated with antibiotic, newborn born to mothers with risk factors for EOS or with maternal clinical chorioamnionitis, or to mothers that were given intra-partum antibiotic prophylaxis (IAP). RESULTS: In the study period, 7058 newborns were born, 1341 (19%) neonates were included according to the inclusion criteria. Six newborns had EOS (0.85 per 1000 live born). 123/1341 (9%) of the neonates were symptomatic of whom six (4.9%) had proven EOS with RR 10.9 (CI 3.5-33.39, p < .0001), NNT was 22.6. Of them, 89/1341 (6.6%) were treated for maternal clinical chorioamnionitis, two (2.25%) had proven EOS, but they were also symptomatic. The RR was 5.03 (CI 1.03-24.6 p = .045) and the NNT was 55.5. Symptomatic newborns were at an increased risk of 2.2 to have EOS compared with newborns with maternal clinical chorioamnionitis. During the study period, 201 (15%) newborns received antibiotic treatment, while if we had only used the calculator, 111 (8%) newborns would have been treated (p<.001). Only one (out of three with maternal risk factors) newborn was symptomatic during the first hour of life. Three of the mothers whose newborn developed EOS, had no risk factors so there was no need for the calculator. The calculated EOS risk at birth for the other three ranged from 0.37 to 0.67. CONCLUSIONS: We suggest that asymptomatic newborns born to mothers with clinical chorioamnionitis should not receive antibiotic treatment automatically.

Reassessing vitamin D supplementation in preterm infants: a prospective study and review of the literature.

Objectives Recommendations for vitamin D (VitD) intake and target serum levels of 25(OH)D in preterm infants are diverse. We hypothesized that preterm infants with low birth weight (BW) have low dietary intake of VitD and therefore should be supplemented with higher amounts of VitD. Methods Infants with BW < 2 kg were supplemented with 600 units of VitD a day during the first 2-6 weeks of life, whereas infants with BW>2 kg continued with the routine supplementation of 400 units of VitD daily. Serum levels of 25(OH)D, calcium, phosphorous, alkaline phosphatase (AP) and parathyroid hormone (PTH) were assessed 24 h after birth and before discharge. The total daily intake of vitD was calculated in each infant. Results Sixty-two infants were enrolled, 49 with BW < 2 kg. After birth, only 24% had sufficient levels of 25(OH)D, whereas before discharge 45 of 54 infants (83%) available for analysis reached sufficient levels of 25(OH)D. All 54 infants demonstrated significant elevation in serum levels of calcium, phosphorous, AP and significant reduction in PTH levels. The total daily intake of VitD was lower than recommended (800-1000 IU/d) in 16 of 45 infants with BW < 2 kg (36%) and in all nine infants with BW>2 kg. Nevertheless, only 2 of 25 infants with insufficient intake of VitD demonstrated insufficient levels of serum 25(OH)D. No case of vitamin D excess was recorded. Conclusions Increased supplementation of VitD (600 IU/d) for premature newborns with BW < 2 kg is effective in increasing both total daily intake of VitD and serum levels of 25(OH)D.

Assessing Patent Ductus Arteriosus (PDA) Significance on Cardiac Output by Whole-Body Bio-impedance.

We evaluated the effectiveness of a whole-body bioimpedance device (NICaS®, NI Medical, Petach Tikva, Israel) to predict the presence of a hemodynamically significant patent ductus arteriosus (PDA) in premature infants. A total of 36 infants less than 35 week's gestation age and birth weights of less than 1750 g were included in the study. Using the NICaS® device, we obtained whole-body bioimpedance measurements of stroke volume index (SI), cardiac output index (CI) and total peripheral resistance index. A total of 61 measurements were taken together with echocardiograph imaging. The study population was divided into three groups according to the echocardiograph results: group 1-small PDA, group 2-moderate PDA, and group 3-large PDA. Both SI and CI significantly increased from a median value of 22.6 ml/m2 and 3.4 l/min/m2 to 23.8 and 3.7, to 39.8 and 5.4 between groups 1, 2 and 3 respectively. The difference was statistically significant between groups 1 and 3 (P = 0.005 for SI and P = 0.002 for CI) and between groups 2 and 3 (P = 0.037 for SI and P = 0.05 for CI). We found statistically significant differences in SI and CI between infants with large PDAs and infants with no or small and medium PDAs. We suggest that these differences can be used in real time, in addition to echocardiography, in assessing the presence of significant PDAs.

Risk factors for third-generation cephalosporin resistant Enterobacteriaceae in gestational urine cultures: A retrospective cohort study based on centralized electronic health records.

Third-generation-cephalosporin resistant Enterobacteriaceae (3GCR-EB) carriage in pregnant women poses challenges for infection control and therapeutic decisions. The factors associated with multidrug resistant Enterobacteriaceae carriage in the gestational period are not well documented. The aim of our study was to identify risk factors associated with 3GCR-EB isolation in gestational urine cultures. The study was designed as retrospective cohort based on centralized electronic health records database. Women delivered in Clalit Health Services hospitals in Israel in 2009-2013 and provided urine culture(s) during pregnancy were included. Multivariable analysis using the Generalized Estimating Equations model was used to assess risk factors for 3GCR-EB isolation in gestational urine cultures. The study included 15,282 pregnant women with urine cultures yielding Enterobacteriaceae (EB). The proportion of 3GCR-EB in EB isolates was 3.9% (n = 603). The following risk factors were associated with 3GCR-EB isolation: multiple hospital admissions during the year before delivery (OR,1.47;95% CI,1.21-1.79), assisted fertilization procedure (OR,1.53; 95% CI,1.12-2.10), Arab ethnicity (OR,1.22; 95% CI,1.03-1.45), multiple antibiotic courses (OR,1.76; 95% CI,1.29-2.40), specifically, cephalosporins (OR,1.56; 95% CI,1.26-1.95), fluoroquinolones (OR,1.34; 95% CI,1.04-1.74), or nitrofurantoin (OR,1.29; 95% CI,1.02-1.64). The risk factors identified by this study for 3GCR-EB in gestation, can be easily generalized for pregnant women in the Israeli population. Moreover, these risk factors, other than ethnicity, are applicable to pregnant women worldwide. The information of previous antibiotic treatments, hospitalization in the last year and assisted fertilization procedure can be easily accessed and used for appropriate infection control practices and antimicrobial therapy.

Reduction of hospital-acquired infections in the neonatal intensive care unit: A long-term commitment.

We instituted quality improvement program. We compare the infection rate before (2011-2012) and after (2013-2015). Central line associated blood stream infection episodes decreased from 15.2 to 2.29 episodes per 1000 catheter days (P = .004). We found two major changes, 1. Hand hygiene increased mainly "before aseptic task", from 69.9% to 89.9% and 2. A significant decrease in the length of the catheter use from 5.4 ±â€¯4.5 before to 4.4 ±â€¯2.5 days after the intervention (P = .001).

Risk Factors for the Development of Delayed TSH Elevation in Neonatal Intensive Care Unit Newborns.

Context: Delayed thyrotropin (TSH) elevation (dTSH) is defined as elevated TSH at the second neonatal screening (after normal TSH levels at the initial screening) in premature, low-birth-weight, and ill newborns, mostly in the neonatal intensive care unit (NICU) setting. The pathogenesis of dTSH is elusive. Objective: To identify the risk factors for dTSH development among newborns in the NICU. Design, Setting, and Patients: A retrospective medical record review of neonates with dTSH was conducted in eight university-affiliated NICUs. Two controls were selected for each patient, matched for sex and birth weight. The risk factors for dTSH were identified by univariate analysis, followed by multivariate analysis. Main Outcome Measures: Maternal variables, types of NICU treatments and procedures, syndromes, and various medical conditions were compared between dTSH patients and their matched controls. Results: We enrolled 100 dTSH patients and 200 matched controls and 46 variables were compared between the two groups. Twelve risk factors for dTSH were identified on univariate analysis: cesarean section, mechanical ventilation, patent ductus arteriosus (PDA), pneumothorax, and administration of cefotaxime, vancomycin, fluconazole, dopamine, ibuprofen, furosemide, insulin, and packed red blood cells. On multivariate analysis, four risk factors were identified: PDA and vancomycin, insulin, and furosemide administration. In 26 twin pairs, in which one twin had dTSH, all variables presented similarly in both twins. Conclusions: Although some variables had direct effects on pituitary-thyroid axis dysfunction, these variables, altogether, reflect the severity of the clinical conditions in the NICU, which is the common basis for dTSH.

Early, rapidly progressive enteral nutrition promotes growth of very low birth weight (VLBW) infants.

AIM: This study describes the effects of a quality improvement program to promote improved postnatal nutrition on the growth of very low birth weight (VLBW) infants. METHODS: Daily data regarding nutrition and growth were collected from the medical record of VLBW infants born during 1995-2010. The infants were grouped by year of birth in order to compare infants from before, during and after the policy change. Evaluation of growth included age in days at a return to birth weight and the proportion of infants with weight below the 10th percentile at discharge. RESULTS: The caloric and protein intake improved significantly. The age at a return to birth weight fell (p < 0.01) from 14.6 ± 5 d to 11 ± 8 d after the change. The proportion of infants with a discharge weight below the 10th percentile for corrected age fell (p < 0.01) from 72.1% to 42.1%. Data on enteral feeding showed that increased rate of enteral feeds (EF) was associated with better growth (p < 0.001). CONCLUSION: Increasing awareness led to increase in caloric and protein intake in VLBW infants. Aggressive EF was associated with more rapid weight gain. However, the provision of protein and calories during the first 2 weeks of life still falls short of the latest European Society of Pediatric Gastroenterology, Hepatology and Nutrition recommendations.

Is there a difference in breast milk fatty acid composition of mothers of preterm and term infants?

OBJECTIVE: Arachidonic acid (ARA) (c20:4 w6) and docosahexanoic acid (DHA) (c22:6 w3) are of major importance for neural maturation and retinal function in infancy. Requirements in preterm infants are increased due to accelerated growth and limited body stores. Data regarding human milk fatty acid composition after preterm and full-term delivery is inconsistent. This study compared fatty acid composition in breast milk from full-term and preterm infants. Findings were correlated with maternal dietary intake. METHODS: Human milk was obtained 4-5 days after full-term delivery (20 infants) and 4-5, 10-11 and 14-15 days after preterm delivery (21 infants, of whom 6 were born before 30 weeks). For fatty acid analysis, lipids were extracted, transesterified and separated by gas liquid chromatography. RESULTS: Total fat content was similar in the two groups. FA composition including LCPUFA and specifically ARA & DHA were similar in full-term and preterm infants and in the sub-set born before 30 weeks. In preterm infants, postnatal age did not influence LCPUFA content. CONCLUSIONS: This study did not detect any effect of gestational age or postnatal age on milk LCPUFA content. Accordingly, the increased demand for LCPUFA and specifically DHA in preterm infants need to be met by other supplementation.

Correlation of transcutaneous bilirubinometry (TcB) and total serum bilirubin (TsB) levels after phototherapy.

AIM: To investigate the correlation between transcutaneous bilirubinometry (TcB) and total serum bilirubin (TsB) in jaundiced infants before and after, but not during phototherapy. METHODS: This study prospectively investigated the correlation between TcB and TsB in term and near term infants before and after phototherapy. RESULTS: Overall 673 pairs of measurements (TcB and TsB) were performed on 371 infants of ≥35 weeks gestation and with birth weight above 2000 g. Of these 337 sets were from 200 infants who had not been treated with phototherapy (Group 1) and 336 measurements from 171 infants taken between 1 h and 5 d after phototherapy (Group 2). The correlation coefficient between TcB and TsB in the whole cohort was r = 0.72. The correlation was low during the first 8 h after phototherapy (r = 0.56), but thereafter the correlation returned to the range of 0.65-0.8. Using the Sobel test, no significant difference was found between the correlation coefficients at the different time periods, with the possible exception of the difference between 1 and 8 h and 9 and 16 h which was of borderline significance with a p value of 0.06. CONCLUSION: This study demonstrates good correlation between TcB and TsB by 8 h after phototherapy. This adds validity to community-based screening programs employing TcB measurements plotted on TsB nomograms. Such programs may contribute to prevention of tragic cases of bilirubin-induced neurologic damage.

Comparison of hematologic indices and markers of infection in umbilical cord and neonatal blood.

OBJECTIVE: Evaluation of a neonate for suspected early neonatal sepsis routinely includes blood tests such as complete blood count, C-reactive protein (CRP) and culture. In order to obviate the need for venepuncture, we prospectively compared these tests in paired samples from umbilical cord and peripheral venous blood drawn during the first hours after birth in both preterm and term infants. METHODS: Paired blood samples were studied from asymptomatic neonates with risk factors for early sepsis. Data were collected on maternal and neonatal factors that may have influenced the correlation between the tests. RESULTS: Three hundred fifty pairs of samples were studied. Significant correlation between umbilical cord and peripheral venous samples was found for white blood cell (WBC; r = 0.683) and platelets (PLT) (r = 0.54). Correlation for hemoglobin was lower (r = 0.36). No cases of early neonatal sepsis were detected. However, contamination rates were 12% in umbilical cord blood and 2.5% in peripheral venous blood cultures. WBC rose after birth and the 90th percentile rose from 22 500 in umbilical cord blood to 29 700 in peripheral blood. CONCLUSIONS: Screening for sepsis with umbilical cord CBC may be useful provided normal ranges are adjusted accordingly.

Limitations of the risk factor based approach in early neonatal sepsis evaluations.

AIM: Guidelines for detection of early neonatal sepsis employ a risk factor approach combined with laboratory parameters. In an era of increasing intrapartum antibiotic prophylaxis (IAP), we re-assessed the approach as a whole and each of the risk factors individually. METHOD: This retrospective study included infants with risk factors for sepsis or those treated with antibiotics or who had documented early sepsis. Safety of the protocol was assessed by the number of cases of either missed or partially treated late sepsis or meningitis and the sepsis-related mortality rate. Predictive value of each clinical and laboratory factor was calculated. RESULTS: Of the 22,215 neonates, 2096 were assessed. IAP among infants with risk factors rose from 68% in 2005 to 78% in 2008 (p = 0.001). A total of 1662 asymptomatic infants had risk factors, 635 received antibiotics and one (0.06%) had sepsis. A total of 434 symptomatic infants were treated with antibiotics and of these 234 had risk factors and 20 (4.6%) had sepsis. No cases of partially treated or missed sepsis were detected. Poor predictive value was found for all risk factors except prematurity and leukopenia. CONCLUSION: The risk factor based approach in asymptomatic infants cannot be justified. In-hospital observation of asymptomatic infants for 2-3 days with antibiotic treatment being reserved only for symptomatic infants may be a reasonable alternative.

The red reflex examination in neonates: an efficient tool for early diagnosis of congenital ocular diseases.

BACKGROUND: The American Academy of Pediatrics recently published recommendations for the red reflex assessment in the newborn period to detect and treat ocular disorders as early as possible, and to prevent lifelong visual impairment and even save lives. The test is technically simple to perform, non-invasive, requires minimal equipment and can detect a variety of ocular pathologies including cataracts and retinal abnormalities. No specific national guidelines exist on this issue. OBJECTIVES: To document the implementation of red reflex examination in routine neonatal care and present the findings. METHODS: Our clinical experience following inclusion of the red reflex test into the newborn physical examination in a single center was reviewed. In addition, an electronic mail questionnaire was sent to all neonatology departments in Israel regarding performance of the red reflex test. RESULTS: During 2007-2008, five infants were identified with congenital cataracts at days 2-6 of life prior to discharge from hospital. Surgery was performed in one infant at age 2 months and all infants underwent a thorough follow-up. The incidence of congenital cataract in our center was 1:2300. Less than half the neonatology departments have endorsed the AAP recommendation and perform the red reflex test routinely. CONCLUSIONS: Abnormal red reflex test after delivery enables a rapid ophthalmologic diagnosis, intervention and close followup. We recommend that red reflex screening be performed as part of the newborn physical examination; if abnormal, an urgent ophthalmologic referral should be made.

Oral insulin supplementation in paediatric short bowel disease: a pilot observational study.

BACKGROUND AND AIM: Insulin is present in human milk, and oral insulin supplementation causes a dramatic adaptive gut growth in a rat model of short bowel syndrome (SBS). We conducted an open-label pilot observational study to examine whether oral insulin supplementation to paediatric patients with SBS decreases the need for parenteral nutrition (PN). METHODS: Between April 2004 and March 2006, 10 premature infants and children were recruited from 8 paediatric gastroenterology centres in Israel, Croatia, and Germany. Enrolled subjects received 1 unit of insulin (Actrapid, Novonordisk, Denmark)/kg body weight per dose x 4/day (every 6 hours) for 28 days. We monitored glucose blood levels, weight, enteral and parenteral intake of calories, carbohydrates, and lipids. In addition, blood levels of albumin, ALT, AST, GGT, ALP, total cholesterol, triglycerides, and anti-insulin antibodies were recorded. RESULTS: On average, enteral intake increased from 45.6% +/- 30.6% to 58.9% +/- 28.2% (not statistically significant), and ALT blood levels decreased from 194 +/- 128 U to 136 +/- 79 U (not statistically significant). Two (2/10) infants were weaned off PN. None of the children developed insulin antibodies. CONCLUSIONS: Oral insulin supplementation in paediatric SBS is not associated with short-term side effects. Although clinical improvement was observed in a subset of children, whether these effects are due to insulin administration is uncertain. The efficacy of oral insulin remains to be determined in a double-blind manner using a preparation that is resistant to degradation in the stomach.

Neonatal aspects of the relationship between intrapartum events and cerebral palsy.

Recent years have witnessed an international, multisource effort to define and progressively improve evidence-based criteria for defining the relationship between perinatal events and the subsequent development of cerebral palsy. The neonatal components of these criteria include neonatal encephalopathy, Apgar score, multisystem organ dysfunction, and currently available neuroimaging methods. This review focuses on current knowledge and unresolved issues regarding these criteria.

Look-back study of Hepatitis C in teenagers after blood transfusions as neonates.

AIM: To conduct a single-centre "look-back" study of the prevalence of hepatitis C in teenagers who had received blood products as newborns, prior to hepatitis C virus (HCV) blood donor screening. METHODS: Using blood bank records, we identified 732 surviving teenagers aged 14-18 years who had received blood products as neonates during 1986-1990. Letters recommending HCV antibody testing were sent to 732 surviving teenagers; 581 recipients were contacted and invited to undergo testing, and, of these, 429 consented (59% of the survivors). HCV antibody testing was performed on all and HCV-RNA was tested on those who were antibody positive. RESULTS: Three teenagers (0.7%, 95% CI 0.54-0.86) tested positive for HCV antibodies and all three were HCV-RNA positive. There were no cases in which antibodies were detected and polymerase chain reaction (PCR) was negative. Two of the three had mildly elevated liver enzymes and all three had mild inflammatory activity and low fibrosis scores on liver biopsy. CONCLUSIONS: The look-back process, even in a single centre with a stable urban population, is relatively inefficient in screening at-risk populations. Although the prevalence of hepatitis C in this sample was relatively low, paediatricians should offer screening to teenagers and young adults who received blood products in the neonatal period.

The fear of necrotizing enterocolitis versus achieving optimal growth in preterm infants--an opinion.

UNLABELLED: Very-low-birthweight (VLBW) infants suffer marked growth delay despite well-intentioned efforts at combining enteral and parenteral nutrition. Fear of necrotizing enterocolitis (NEC) has traditionally influenced neonatologists toward delaying and progressing slowly with enteral feeding, while supporting the infant with parenteral nutrition. Current evidence suggests significant benefits of enteral feeding that is started early and advanced at rates of 20-35 ml/kg/d. CONCLUSION: We conclude that fear of inadequate growth should replace the fear of NEC in guiding nutritional strategies for these infants.
