Days Of Total Parenteral Nutrition Research Articles

Better clinical outcomes and lower triggering of inflammatory cytokines for allogeneic hematopoietic cell transplant recipients treated in home care versus hospital isolation - the Karolinska experience.

After allogeneic hematopoietic cell transplantation (Allo-HCT) and conditioning, patients are typically placed in isolated hospital rooms to prevent neutropenic infections. Since 1998, we've offered an alternative: home care for patients living within a one to two-hour drive of the hospital. In Sweden this approach includes daily visits by an experienced nurse and daily phone consultations with a unit physician. When necessary, patients receive transfusions, intravenous antibiotics, and total parenteral nutrition at home. Our initial study report compared 36 home care patients with 54 hospital-treated controls. Multivariate analysis found that home care patients were discharged earlier to outpatient clinics, required fewer days of total parenteral nutrition, had less acute graft-versus-host disease (GVHD) grade II-IV, and lower transplantation-related mortality (TRM) and lower costs. Long-term follow-up showed similar chronic GVHD and relapse rates in both groups, with improved survival rates in the home care group. A subsequent comparison of 146 home care patients with hospital-treated controls indicated that home care and longer home stays were associated with lower grades of acute GVHD. Home care was found to be safe and beneficial for children and adolescents. Over two decades, 252 patients received home care post-Allo-HCT without any fatalities at-home. Ten-year outcomes showed a 14% TRM and a 59% survival rate. In 2020, an independent center confirmed the reduced risk of acute GVHD grades II-IV for patients treated in home care. Here, we report for the first time that home care patients also demonstrate a less inflammatory systemic cytokine profile. We found higher levels of IFN-γ, IL-2, IL-5, IL-13, GM-CSF, and G-CSF, but lower VEGF in hospital-treated patients, which may contribute to acute GVHD grades II-IV. In conclusion, home-based treatment following Allo-HCT yields multiple promising clinical outcomes and improved systemic inflammatory markers, which may contribute to less development of life-threatening GVHD.

Opioid and Methadone Use for Infants With Surgically Treated Necrotizing Enterocolitis

Necrotizing enterocolitis (NEC) requiring surgical intervention is the most common reason for surgical procedures in preterm neonates. Opioids are used to manage postoperative pain, with some infants requiring methadone to treat physiologic opioid dependence or wean from nonmethadone opioid treatment during recovery. To describe postoperative opioid use and methadone treatment for infants with surgically treated NEC and evaluate postoperative outcomes. A cohort study of infants with surgically treated NEC admitted from January 1, 2013, to December 31, 2022, to 48 Children's Hospital Association hospitals contributing data to the Pediatric Health Information System (PHIS) was performed. Infants who received methadone preoperatively, were aged 14 days or less at the time of the operation, had a congenital heart disease-related operation, or died within 90 days of the operation were excluded. Mixed-effects multivariable logistic regression was used to evaluate thresholds for duration of opioid use after the operation associated with methadone treatment and clinical outcomes associated with methadone use were enumerated. Postoperative administration of nonmethadone opioids. Methadone use and postoperative length of stay, ventilator days, and total parenteral nutrition (TPN) days. Of the 2037 infants with surgically treated NEC identified, the median birth weight was 920 (IQR, 700.0-1479.5) g; 1204 were male (59.1%), 911 were White (44.7%), and 343 were Hispanic (16.8%). Infants received nonmethadone opioids for a median of 15 (IQR, 6-30) days after the operation and 231 received methadone (11.3%). The median first day of methadone use was postoperative day 18 (IQR, days 9-64) and continued for 28 days (IQR, 14-73). Compared with infants who received nonmethadone opioids for 1 to 5 days, infants receiving 16 to 21 days of opioids were most likely to receive methadone treatment (odds ratio, 11.45; 95% CI, 6.31-20.77). Methadone use was associated with 21.41 (95% CI, 10.81-32.02) more days of postoperative length of stay, 10.80 (95% CI, 3.63-17.98) more ventilator days, and 16.21 (95% CI, 6.34-26.10) more TPN days. In this cohort study of infants with surgically treated NEC, prolonged use of nonmethadone opioids after the operation was associated with an increased likelihood of methadone treatment and increased postoperative length of stay, ventilation, and TPN use. Optimizing postoperative pain management for infants requiring an operation may decrease the need for methadone treatment and improve health care use.

Elective Delivery versus Expectant Management for Gastroschisis: A Systematic Review and Meta-Analysis.

The optimal timing of delivery for pregnancies complicated by prenatally diagnosed gastroschisis remains controversial. Therefore, the aim of this study was to find whether elective or expectant delivery is associated with improved neonatal outcome. MEDLINE and Embase databases were searched for studies up to 2021 that reported timing of delivery for prenatally diagnosed gastroschisis. A systematic review and meta-analysis were then performed in group 1: moderately preterm (gestational age [GA]: 34-35 weeks) elective delivery versus expectant management after GA 34-35 weeks; and group 2: near-term (GA: 36-37 weeks) elective delivery versus expectant management after GA 36-37 weeks. The following clinical outcomes were evaluated: length of stay (LOS), total parenteral nutrition (TPN) days, bowel morbidity (atresia, perforation, and volvulus), sepsis, time of first feeding, short gut syndrome and respirator days, and mortality. Two randomized controlled trials (RCT)s and eight retrospective cohort studies were included, comprising 629 participants. Moderately preterm elective delivery failed to improve clinical outcomes. However, near-term elective delivery significantly reduced bowel morbidity (7.4 vs. 15.4%, relative risk = 0.37; 95% confidence interval [CI]: 0.18, 0.74; p = 0.005; I2 = 0%) and TPN days (mean difference =-13.44 days; 95% CI: -26.68, -0.20; p = 0.05; I2 = 45%) compared to expectant delivery. The mean LOS was 39.2 days after near-term delivery and 48.7 days in the expectant group (p = 0.06). Based on the data analyzed, near-term elective delivery (GA 36-37 weeks) appears to be the optimal timing for delivery of pregnancies complicated by gastroschisis as it is associated with less bowel morbidity and shorter TPN days. However, more RCTs are necessary to better validate these findings.

Effects of Probiotics on Gut Microbiomes of Extremely Preterm Infants in the Neonatal Intensive Care Unit: A Prospective Cohort Study.

Background: Probiotics have been previously reported to reduce the incidence of necrotizing enterocolitis (NEC) in extremely preterm infants, but the mechanisms by which the probiotics work remain unknown. We aimed to investigate the effects of probiotics on the gut microbiota of extremely preterm infants. Methods: A prospective cohort study was conducted on 120 extremely preterm neonates (gestational age ≤ 28 weeks) between August 2019 and December 2021. All neonates were divided into the study (receiving probiotics) and the control (no probiotics) groups. Multivariate logistic regression analysis was performed to investigate the significantly different compositions of gut microbiota between these two groups. The effects of probiotics on the occurrence of NEC and late-onset sepsis were also investigated. Results: An increased abundance of Lactobacillus was noted in neonates who received the probiotics (AOR 4.33; 95% CI, 1.89–9.96, p = 0.009) when compared with the control group. Subjects in the probiotic group had significantly fewer days of total parenteral nutrition (median [interquartile range, IQR]) 29.0 (26.8–35.0) versus 35.5 (27.8–45.0), p = 0.004) than those in the control group. The probiotic group had a significantly lower rate of late-onset sepsis than the control group (47.1% versus 70.0%, p = 0.015), but the rate of NEC, duration of hospitalization and the final in-hospital mortality rates were comparable between these two groups. Conclusions: Probiotic supplementation of extremely preterm infants soon after the initiation of feeding increased the abundance of Lactobacillus. Probiotics may reduce the risk of late-onset sepsis, but further randomized controlled trials are warranted in the future.

Fentanyl Exposure in Preterm Infants: Five-Year Neurodevelopmental and Socioemotional Assessment.

ObjectiveTo evaluate the association between cumulative fentanyl dose during neonatal intensive care and 5-year neurodevelopmental and socioemotional outcomes in very preterm infants.Materials and MethodsPatient demographics and clinical factors during the perinatal and neonatal course were collected in 84 patients born between 23- and 30-weeks gestational age (GA). Cumulative fentanyl dose during neonatal intensive care was calculated. Developmental testing at age 5 years included the Wechsler Preschool and Primary Scale of Intelligence Full-Scale Intelligence Quotient, Third Edition, Clinical Evaluation of Language Fundamentals-Preschool, Second Edition, Movement Assessment Battery for Children, Second Edition (MABC-2), and Shape School Assessment. Socioemotional outcomes were assessed via caregiver's responses on the Child Behavior Checklist/1.5-5 (CBCL/1.5-5.5) and Social Responsiveness Scale, Second Edition (SRS-2). Covariates were identified on bivariate analysis (p < 0.1). Linear regression models related outcome measures to the log of cumulative fentanyl dose adjusted for covariates.ResultsHigher cumulative fentanyl dose was associated with lower composite motor scores on bivariate analysis (p < 0.01). Cumulative fentanyl dose did not correlate with composite intelligence quotient, language, or executive function. The Clinical Risk Index for Babies score, log of mechanical ventilation, inotrope, and anesthesia duration, and log of cumulative midazolam and hydrocortisone dose were also associated with MABC-2 scores (p < 0.1). Cumulative fentanyl dose was not associated with composite MABC-2 scores on multiple linear regression. Higher cumulative fentanyl dose was associated with decreased socioemotional problems based on caregiver's response on CBCL/1.5-5.5 t-scores driven by fewer symptoms of depression. The McMaster Family Assessment Device general functioning scale score, maternal age, GA, log of total parenteral nutrition days, patent ductus arteriosus requiring treatment, and log of inotrope hours were also associated with CBCL/1.5-5.5 t-scores (p < 0.1). Cumulative fentanyl dose (p = 0.039) and family dysfunction score (p = 0.002) remained significant after controlling for covariates on multiple linear regression.ConclusionCumulative fentanyl dose during neonatal intensive care did not correlate with 5-year motor, cognitive, or language outcomes after controlling for other variables. Fentanyl dose was associated with caregiver reported total socioemotional problems on the CBCL/1.5-5.5 on multivariate modeling. Additional long-term studies are needed to fully elucidate the safety of fentanyl in very preterm neonates.

*O-29: Medical Predictors of Social-emotional and Adaptive Functioning in School-Age Pediatric Intestinal Failure

Introduction: Long-term survival in pediatric intestinal failure (IF) has improved over recent decades due to medical/surgical advances and the development of multi-disciplinary rehabilitation programs. Focus has shifted towards identifying neurodevelopmental morbidities and promoting optimal quality of life. There has been little exploration into social-emotional and adaptive functioning. Methods: Children (4-18 years) in our IF rehabilitation program underwent neuropsychological assessments (2012-2019) which included caregiver- and teacher-reported social-emotional (BRIEF/BRIEF-2, BASC-2/BASC-3) and adaptive (ABAS-II/ABAS-3, SIB-R, Vineland-II, BASC-2/BASC-3) functioning questionnaires. Results were compared to age-matched norms (mean=100; SD=15) using one-sample z-tests. Medical variables showing ≥3 significant correlations with social-emotional and adaptive functioning outcomes were included in linear regression analyses to explore medical factors independently associated with psychological outcomes. Results: Overall, 74 children (55% males) underwent assessments (median assessment age: 6.5 years, IQR:6.1-8.1). Most children (72%) were premature (median gestational age [GA]: 34 weeks, IQR:29-37; median birth weight [BW]: 2.1kg, IQR:1.1-2.6). The most frequent IF etiology was necrotizing enterocolitis (NEC; 32%). Although caregiver- and teacher-report indicated broadly average-range mean scores, given the standard deviations, the group performed significantly poorer than age-matched norms on executive functioning, internalizing emotional problems (i.e., anxiety, depression, somatization), and adaptive functioning (Figure). GA, NEC diagnosis, duration of first year hospitalization, and total ambulatory clinic appointments correlated with ≥3 social-emotional and adaptive functioning outcomes while BW, small and large bowel length, total septic episodes, and total parenteral nutrition days did not. In the regression, adjusted for GA, NEC diagnosis predicted internalizing emotional problems. Duration of first year hospitalization and total ambulatory clinic appointments were both non-significant. Conclusions: Relative to population norms, the group displayed executive dysfunctions, emotional issues, and poor adaptive functioning. NEC diagnosis and GA, rather than IF related factors, posed heightened risk for emotional issues. Future research should explore demographic risk factors to further inform clinical screening and targeted intervention.Figure.: Social-Emotional and Adaptive Functioning in School-Age Pediatric Intestinal Failure Compared to Age-Matched Population Norms.

Outcome of primary peritoneal drainage in perforated necrotizing enterocolitis: an experience with 96 infants

Background: Necrotizing enterocolitis is a life-threatening inflammation of neonatal intestine of multifactorial etiology. In early stages, medical management is considered; while as a transmural disease with pneumatosis or perforation needs surgical attention. Primary peritoneal drainage has evolved as an alternative to classic exploratory laparotomy especially in sick preterm and very low birth weight infants.Methods: In our study, we tried to employ primary peritoneal drainage as an initial intervention in all surgical necrotizing enterocolitis patients and analyzed the results and final outcome in terms of total days in neonatal intensive care unit, total parenteral nutrition days, days to start oral feeds, need for laparotomy, mortality and other complications.Results: Around one-third patients were either very low or extremely low birth weight and 80% patients were preterm. Primary peritoneal drainage was successful without need for laparotomy in around 65% of patients. In the rest 34 patients, 24 were subjected to rescue laparotomy, while 10 could not be stabilized for major surgery. Overall mortality was 29.16%.Conclusions: Early bedside primary peritoneal drainage can be employed in all cases of NEC with perforation with rescue laparotomy to be determined by subsequent monitoring. This strategy seems to be safe and cost-effective in a resource challenged set up and lifesaving in sick and extremely low birth weight infants.

Routine prefeed gastric aspiration in preterm infants: a systematic review and meta-analysis.

Despite lack of evidence, the practice of routine prefeed gastric residue aspiration before the next feed is common. Recent studies suggest that this practice might be even harmful. Therefore, we aimed to evaluate the effect of avoiding routine prefeed gastric residue aspiration as compared to routine aspiration, on various clinical outcomes in preterm infants. We searched five different electronic databases (MEDLINE, EMBASE, Web of Science, CINAHL, and Cochrane Library) until March 8, 2021. Only randomized controlled trials comparing the practice of routine prefeed gastric aspiration with no routine aspiration in preterm infants were considered eligible. The random-effects meta-analysis was done using RevMan 5.3 software. Of the 894 unique records identified by our search, we included 6 studies (451 participants) in the review. There was no significant difference in the incidence of necrotizing enterocolitis (RR 0.80; 95% CI 0.31 to 2.08; 421 participants in 5 trials). Avoiding routine prefeed aspiration was associated with achieving full enteral feeds earlier (MD - 3.19 days, 95% CI - 4.22 to - 2.16), shorter duration of hospitalization (MD - 5.32 days; 95% CI - 10.25 to - 0.38), and lower incidence of late-onset sepsis (RR 0.77; 95% CI 0.60 to 0.99). Time to regain birth weight, days of total parenteral nutrition or central venous line usage, culture-positive sepsis, and all-cause mortality did not differ between the two groups.Conclusion: In the absence of other signs of feed intolerance, routine prefeed gastric residue aspiration should be avoided in preterm infants.Prospero registration number: CRD42020197657 What is Known: • Though, routine prefeed aspiration before next feed is a common practice in preterm gavage-fed infants. • Recent study suggests that the omission of routine gastric residual evaluation led to improved weight gain and earlier hospital discharge. What is New: • Low- to moderate-quality evidence suggest that avoiding routine prefeed gastric residue monitoring helps in the reduction of late-onset sepsis, achieving full enteral feeds earlier, and earlier discharge from the hospital. • Abandoning the practice of routine prefeed aspiration in absence of other signs of feed intolerance in preterm low birthweight neonates is safe.

Estimating Length of Stay for Simple Gastroschisis

BackgroundLength of stay (LOS) is an important measure of quality; however, estimating LOS for rare populations such as gastroschisis is problematic. Our objective was to identify explanatory variables for LOS and build a model to estimate LOS in neonates with simple gastroschisis. MethodsIn 73 neonates with simple gastroschisis (47% female, 67% White), statistical correlations for 31 potential explanatory variables for LOS were evaluated using multivariate linear regression. Poisson regression was used to estimate LOS in predetermined subpopulations, and a life table model was developed to estimate LOS for simple gastroschisis. ResultsFemale sex (−2.4 d), “time to silo placement” (0.9 d), total parenteral nutrition days (0.6 d), need for any nasogastric feedings (11.4 d) and at discharge (−7 d), “feeding tolerance” (0.4 d), days to first postoperative stool (−0.3 d), and human milk exposure (−3.4 d) associated with LOS in simple gastroschisis. Estimated LOS for preterm neonates was longer than term infants (5.4 versus 4.6 wk) but similar for estimates based on sex and race. Based on these associations, we estimate that >50% of neonates with simple gastroschisis will be discharged by hospital day 35. ConclusionsWe identified several associations that explained variations in LOS and developed a novel model to estimate LOS in simple gastroschisis, which may be applied to other rare populations.

Severe hypomagnesaemia and severe hypophosphatemia in adults icu patients receiving total parenteral nutrition

Rationale: Severe mineral disorders are significantly associated with increased need for mechanical ventilation, prolonged ICU stay and increased mortality. The purpose of this study is to evaluate the prevalence of severe hypophosphatemia and hypomagnesaemia prior and within the first 7 days of total parenteral nutrition (TPN) infusion in ICU patients.

1042-P: Insulin Requirement during Total Parenteral Nutrition in Patients with Diabetes Mellitus

Glycemic control in patients with diabetes mellitus receiving total parenteral nutrition (TPN) can be challenging due to multiple factors. These patients often have a high burden of illness and receive medications that raise blood glucose (BG) levels. Moreover, TPN delivers a large amount of glucose directly into the systemic circulation without the benefit of incretin effect. Therefore, relatively large amounts of insulin are expected to be required for glycemic control. However, there are no studies to guide insulin dosing in patients with diabetes being started on TPN. We conducted a retrospective study including all patients with diabetes admitted to our hospital over a 1-year period who received TPN for ≥ 3 days. The goal of this study was to estimate a safe starting dose of insulin for TPN. Patients receiving enteral nutrition along with TPN were excluded. Insulin doses and blood glucose levels on the last day of TPN were used for data analysis. We found 25 patients who fulfilled our inclusion/exclusion criteria. All patients had type 2 diabetes and were receiving antidiabetic drugs before hospitalization. Mean age was 68 ± 7 years, 56% were men, 80% were White, 44% had microvascular and 44% had macrovascular complications. Mean BMI was 26.7 ± 6.7 kg/m2, systolic BP 131 ± 27 mmHg, diastolic BP 65 ± 15 mmHg, HbA1c 7.7 ± 2.3% and serum creatinine 2.7 ± 3.3 mg/dl. The mean daily BG on TPN was 212 ± 47 mg/dl. Out of 171 BG values available on the last day of TPN, 116 (68%) were &amp;gt;180 mg/dl, 4 (2%) were &amp;lt;70 mg/dl and 0 were &amp;lt;40 mg/dl. Only two patients suffered mild hypoglycemic episodes while all others remained hyperglycemic. Average total daily insulin dose was 17 ± 20 units before starting TPN and 53 ± 54 units on the last day of TPN. Patients received an average of 0.7 Units/kg total daily dose of insulin on the last day of TPN. With this dose, they had minimal risk of hypoglycemia but the glucose levels were often high. Our study shows that the majority of patients with diabetes need more than 0.7 units/kg insulin when receiving TPN. Disclosure R. Garg: None. A. Arunachalam: None. L.E. Bermudez: None. M.

Early versus late fortification of breast milk in preterm infants: a systematic review and meta-analysis.

This systematic review and meta-analysis assessed the effects of early fortification (EF) versus late fortification (LF) of breast milk (BM) on growth of preterm infants. Randomized and quasi-randomized controlled trials (RCTs) dealing with the effects of EF versus LF on growth parameters, incidence of adverse events, and duration of hospital stay in preterm infants were included. Data were pooled using the RevMan 5.3 software. Quality of evidence for predefined outcomes was analyzed by GRADE. Available evidence (3 RCTs, 309 preterm infants) showed no statistically significant difference between EF and LF of BM for any of the growth parameters-weight (standardized mean difference (SMD) 0.13; 95% confidence interval (CI) - 0.09, 0.36); length (SMD 0.02; 95% CI - 0.20, 0.25); and head circumference (SMD - 0.10; 95% CI - 0.33, 0.12). Total parenteral nutrition days were similar. Duration of hospital stay was significantly higher with EF (MD 4.29; 95% CI 0.84, 7.75) with a trend of non-significant increase in feed intolerance and necrotizing enterocolitis (NEC).Conclusion: Very low quality evidence did not find any significant difference in growth parameters of preterm infants in association with EF or LF of BM. A significant increase in hospital stay and non-significant increase in feed intolerance and NEC were associated with EF.PROSPERO registration number: CRD42019139235What is Known:• Fortification of breast milk with essential macro- and micronutrients is necessary for optimization of nutrition in preterm infants.• There is no consensus regarding the breast milk feeding volume at which fortification should be initiated.What is New:• Very low quality evidence showed no significant difference between early and late fortification of breast milk on growth parameters of preterm infants.• Early fortification was associated with non-significant increase in feed intolerance and necrotizing enterocolitis and a significant increase in hospital stay.

Neonatal Intensive Care Unit-Specific Lactation Support and Mother's Own Breast Milk Availability for Very Low Birth-Weight Infants.

Mother's own milk (MOM) is the preferred nutrition for premature infants, particularly for the very low birth-weight (VLBW) cohort. Benefits are well documented; yet, numerous barriers exist for provision of MOM in the neonatal intensive care unit (NICU). Lactation consultants (LCs) can optimize breastfeeding support for NICU mothers; however, understanding of the impact of NICU-dedicated LCs is limited. Evaluate the effectiveness of NICU-dedicated LCs in improving breastfeeding outcomes and MOM provision in VLBW infants. A retrospective chart review of 167 VLBW infants comparing breastfeeding outcomes between 2 NICUs, one with NICU-dedicated LCs (hospital A; n = 48) and one without (hospital B; n = 119). Primary outcome measures included feeding percentages of MOM received by infants at 3 intervals, throughout hospitalization, and number of direct breastfeeding events. Secondary outcome measures included number of days to first enteral feed, days to reach full feeds, days of nil per os, days on total parenteral nutrition, and length of stay. Neonatal intensive care unit-specific lactation support increased the number of direct breastfeeding events on day of discharge (P = .048). No statistical significance was found at each of the 3 time intervals, or throughout hospitalization (week 1: P = .18; midpoint: P = .40; discharge: P = .16; total hospitalization: P = .19). No statistical significance was demonstrated in secondary outcome measures (days to first enteral feed: P = .22; days to full feeds: P = .25; nil per os days: P = .27; total parenteral nutrition days: P = .34; length of stay: P = .01). Length of stay not found to be significant after correcting for confounding variables. Increased direct breastfeeding events on day of discharge with exposure to NICU-dedicated LCs in the VLBW population. Prospective studies regarding NICU-specific lactation support with larger samples are warranted.

Routine monitoring of gastric residual for prevention of necrotising enterocolitis in preterm infants

P1.55: Does BMI Correlate with Enteral Autonomy Post Intestinal transplant?

Introduction: Intestinal transplant recipients often require total parenteral nutrition (TPN) support in the post-operative period until they achieve enteral autonomy. The time to enteral autonomy is a meaningful clinical outcome and indicator of successful graft function. Further, minimizing TPN exposure in the heavily immunosuppressed patient may mitigate infectious risk. TPN dependence after intestinal transplantation is variable and nutritional status at the time of transplant may be a determinant of the duration of TPN dependence. Body Mass Index (BMI) is one surrogate of nutritional status in the adult population. The aim of this study was to assess how BMI at the time of transplant impacts the duration of TPN after transplant. Methods: Adult patients who received an intestinal transplant at Georgetown University Hospital from 2006 to 2018, and survived beyond one year after transplant were retrospectively identified. BMI at the time of transplant was categorized based on current definitions (<18.5 indicates malnutrition, 18.5–24.9 healthy weight, 25–29.9 overweight, and >29.9 obesity), and compared to duration of TPN dependence in days. Results: 105 adult patients transplanted between 2006 and 2018 were included in the analysis. 51 of the patients were male and 54 were female. Median age was 43 years (range 18–66). Across all BMI categories the average days of TPN was 19.9 ± 12.6 days. Patients with a higher BMI at the time of transplant had the shortest duration of TPN post-transplant. Patients with a BMI of >30 (n= 11) had a mean of 16.1 ± 7.2 days; patients between 25–29.9 (n = 21) had an average of 18.9 ± 9.2 days; patients between 18.6–24.9 (n = 63) had an average of 20.6 ± 14.8 days; lastly, patients <18.5 (n = 10) had an average of 23.9 ± 8.7 days. There was a significant difference in duration of TPN in days between the <18.5 BMI and >30 BMI category (p=0.05) Conclusion: Achievement of enteral autonomy post-intestinal transplant is multifactorial. It is well established that post-transplant surgical and immunological complications are important factors that play a role in determining when TPN can be successfully weaned. Pre-transplant factors, however, may also contribute to enteral autonomy, such as recipient BMI at the time of transplant. Transplant practitioners should assist patients in avoiding a <18.5 BMI pre-transplant in order to potentially decrease the duration of TPN dependence post-transplant.

Effect of colostrum given within the 12 hours after birth on feeding outcome, morbidity and mortality in very low birth weight infants: a prospective cohort study.

The current study aims to compare the feeding outcome, morbidity and mortality in very low birth weight (VLBW) infants who received early colostrum (<12 hours of life) and those who did not. All VLBW infants admitted to neonatal intensive care unit (NICU) were eligible for the study. Eligible infants were enrolled after obtaining written informed consent from either of the parents. Newborns who received colostrum within the first 12 hours after birth formed the study cohort and all others the control cohort. Both cohorts were followed till discharge from NICU. During the study period, 205 VLBW infants were admitted in NICU of whom 171 (83%) infants were enrolled in the study. Both study groups were comparable for mean birth weight, mean gestation and male sex. The proportion of infants with abnormal Doppler was significantly higher in the control group. All outcomes were adjusted for antenatal Doppler abnormalities. The primary outcome of time to reach full feeds in the study population was 6.90 ± 4.4 days as compared to 9.80 ± 4.86 days in the control group with a significant weighted mean difference of -2.4 (-0.8 to -3.9) days. Duration of total parenteral nutrition (TPN) days and mortality were all lower in the study cohort. Risk of sepsis and necrotising enterocolitis was similar in the both groups. Enteral colostrum within first 12 hours of birth in VLBW infants reduces the time to reach full feeds, TPN days and mortality.

Motor Proficiency and Generalized Self-Efficacy Toward Physical Activity in Children With Intestinal Failure.

Survival rates of children with intestinal failure have increased; however, associated co-morbidities may affect long-term motor developmental outcomes. This study evaluates motor proficiency and generalized self-efficacy toward physical activity (PA) in children ages 6 to 12 years with intestinal failure. This is an observational, cross-sectional study of children followed in a multidisciplinary intestinal rehabilitation program. Motor proficiency was assessed using the Bruininks-Oseretsky Test of Motor Proficiency-2 Short Form (BOT-2 SF) and the Scales of Independent Behavior (parent-proxy report). Children completed the Children's Self-Perceptions of Adequacy in and Predilection for Physical Activity (CSAPPA) and a PA questionnaire. Relevant demographic and medical variables were correlated with assessment results. Participants include 30 children (18 males), median age 7 years (interquartile range [IQR] 6-9) with gestational age 35 weeks (IQR 32-39) and birth weight 2.13 kg (IQR 1.68-2.77). Thirteen (43%) were dependent on parenteral nutrition. Fifteen (50%) scored below average on the BOT-2 SF. Lower BOT-2 SF scores were significantly associated with lower CSAPPA scores (r = 0.480, P = 0.01), with a common barrier to PA being the presence of a central line or enterostomy tube. Gestational age, height z scores, length of hospital admissions, and number of septic events were all significantly correlated with lower scores in motor proficiency. Number of septic events and total parenteral nutrition days were significant predictors of lower BOT-2 SF scores, when adjusting for birth weight. Multiple medical variables related to intestinal failure may affect motor proficiency and PA self-efficacy. Developmental follow-up is important to optimize motor skill development and promote PA participation.

Risk factors for healthcare-associated Clostridium difficile infection in pediatric hematopoietic stem cell transplant recipients

BackgroundLimited published literature exists to identify unique risk factors for Clostridium difficile infection (CDI) in pediatric hematopoietic stem cell transplantation (HSCT) recipients. Our objective was to describe the epidemiology of CDI in pediatric patients undergoing HSCT and to identify potential risk factors for CDI.MethodsThis IRB-waived, single-center retrospective review included Duke University Hospital (DUH) patients 12 months of age or older admitted to pediatrics between March 1, 2012 and August 23, 2016 undergoing initial HSCT during the index hospitalization. The primary endpoint (PCR-confirmed CDI within 100 days post-transplantation) was characterized using descriptive statistics. Transplant type, prior CDI history, days of total parenteral nutrition (TPN), and antibiotic use intensity scores were compared between occurrence groups using Pearson’s chi-square, Wilcoxon rank-sum or Student’s t tests as appropriate.Results207 subjects (most Caucasian [55%] and male [61%]) were included, and 15 (7.2%) died. CDI occurred in 24 (12%) within a median (interquartile range) of 35 (9, 47) days since HSCT, and most (92%) were hospital-onset. All cases were healthcare-associated and mild-moderate in severity. None of the patients experienced CDI-related complications. CDI-positive and CDI-negative patients were similar with regards to demographics. Higher median (adjusted) days of TPN (80.6 vs. 29, P < 0.0001) and antibiotic use intensity scores (382.8 vs. 191.0, P < 0.0001), respectively, were associated with CDI. No significant differences between these groups were observed with regard to transplant type (P = 0.28) and prior CDI history (P = 0.10).ConclusionCDI occurred in 12% of pediatric patients within 100 days of undergoing initial HSCT. Onset of this mild-moderate, uncomplicated disease occurred within a median of 35 days and commonly during hospitalization. Patients with CDI were more likely to have increased use of TPN and a higher antibiotic use intensity score.Disclosures All authors: No reported disclosures.

Bone Mineral Density According to Dual Energy X-ray Absorptiometry is Associated with Serial Serum Alkaline Phosphatase Level in Extremely Low Birth Weight Infants at Discharge

To examine bone mineral density in extremely low birth weight infants at discharge and investigate whether serial measurements of serum alkaline phosphatase (ALP) and phosphate can predict bone mineralization. The individuals were 70 preterm infants. Serum calcium, phosphate, and ALP were measured at weekly intervals during admission in extremely low birth weight infants (mean gestational age, 25.3±2.1 weeks; birth weight, 812.8±141.1g). Bone mineral apparent density (BMAD) of the lumbar spine was prospectively evaluated by dual energy X-ray absorptiometry at discharge (n=70). BMAD was classified as poor (<25th percentile) at <0.014g/cm3, fair (25th-75th percentile) at <0.014-0.021g/cm3, and good (>75th percentile) at >0.021g/cm3, based on the distribution of BMAD values in infants with noncomplicated courses of prematurity (n=43). In a further multivariate analysis, the number of total parenteral nutrition days, phosphate at 2 postnatal weeks and 3 postnatal weeks, and ALP at 4 postnatal weeks and 5 postnatal weeks had an impact on bone mineral density at the lumbar spine, independent of gestational age and body weight. Peak ALP activities exceeding 650IU/L revealed low bone mineral density with 80% sensitivity and 64% specificity (AUC, 0.70; p=0.005). Serial measurements of serum ALP and phosphate are associated with decreased bone mineralization by dual energy X-ray absorptiometry at discharge in extremely low birth weight infants.
