Brain Behav Immun 2024; 119:693-708. [PMID: 38677626 DOI: 10.1016/j.bbi.2024.04.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 04/03/2024] [Accepted: 04/22/2024] [Indexed: 04/29/2024] Open
Abstract
Newborns exposed to birth asphyxia transiently experience deficient blood flow and a lack of oxygen, potentially inducing hypoxic-ischaemic encephalopathy and subsequent neurological damage. Immunomodulatory components in plasma may dampen these responses. Using caesarean-delivered pigs as a model, we hypothesized that dietary plasma supplementation improves brain outcomes in pigs exposed to birth asphyxia. Mild birth asphyxia was induced by temporary occlusion of the umbilical cord prior to caesarean delivery. Motor development was assessed in asphyxiated (ASP) and control (CON) piglets using neonatal arousal, physical activity and gait test parameters before euthanasia on Day 4. The ASP pigs exhibited increased plasma lactate at birth, deficient motor skills and increased glial fibrillary acidic protein levels in CSF and astrogliosis in the putamen. The expression of genes related to oxidative stress, inflammation and synaptic functions was transiently altered in the motor cortex and caudate nucleus. The number of apoptotic cells among CTIP2-positive neurons in the motor cortex and striatal medium spiny neurons was increased, and maturation of preoligodendrocytes in the internal capsule was delayed. Plasma supplementation improved gait performance in the beam test, attenuated neuronal apoptosis and affected gene expression related to neuroinflammation, neurotransmission and antioxidants (motor cortex, caudate). We present a new clinically relevant animal model of moderate birth asphyxia inducing structural and functional brain damage. The components in plasma that support brain repair remain to be identified but may represent a therapeutic potential for infants and animals after birth asphyxia.

Ital J Pediatr 2022; 48:146. [PMID: 35971138 PMCID: PMC9380332 DOI: 10.1186/s13052-022-01342-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 08/09/2022] [Indexed: 11/10/2022] Open
Abstract
Background The practice of therapeutic hypothermia (TH) is widely used for neonatal hypoxic-ischemic encephalopathy (HIE) despite its corresponding feeding strategies are still controversial. This randomized controlled trial (RCT) demonstrated to evaluate the effect of early vs. delayed enteral nutrition on the incidence of feeding intolerance (FI) and other association during TH. Methods This single center, parallel-group, and no-blinded RCT was processed in a level III, and academic neonatal intensive care unit. Infants who were diagnosed with HIE and undertaken TH from September 2020 to August 2021 were enrolled. Participants were randomized to receive enteral nutrition either during TH/rewarming (early enteral nutrition, EEN) or after TH (delayed enteral nutrition, DEN) according to a recommend enteral feeding protocol. All data were analyzed using SPSS 26.0 software with a p-value< 0.05 was considered statistically significant. Results Ninety-two infants were enrolled after randomization, but 12 (13.04%) cases including 3 (3.26%) deaths were excluded from eventually analyzed, who did not initiate or discontinue the intervention. 80 cases (42 and 38 in the EEN and DEN group, respectively) who completed the interventions were eventually analyzed. Besides initial time of enteral feeds, two groups had processed the same feeding method. Total 23 (25.0%) cases developed FI, and no difference of morbidity was found between two groups (23.4% vs 26.7%, p = 0.595; Log Rank, p = 0.803). There was no case died or developed late-onset bloodstream and no difference of the incidence of hypoglycemia or weight gain was found (p > 0.05). The percentage of infants who had not reaching the goal of full enteral feeding volume between the two groups was similar (21.43% vs 23.68%, p = 0.809). The average time of parenteral nutrition, reaching full enteral feeds and hospital stay were shorter in the EEN group compared with the DEN group with significant differences (8.81 ± 1.67 vs 10.61 ± 2.06 days, p < 0.001; 9.91 ± 1.88 vs 12.24 ± 2.50 days, p < 0.001; 12.55 ± 4.57 vs 16.47 ± 5.27 days, p = 0.001 respectively). Conclusions Compared with delayed enteral nutrition, introduction of early enteral nutrition according to a recommend feeding strategy for neonatal HIE undergoing TH may be feasible and safe.FI is frequent in this high-risk group of infants which should not be ignored during feeding process.

Abstract
BACKGROUND Parenteral nutrition is commonly administered during therapeutic hypothermia. Randomised trials in critically ill children indicate that parenteral nutrition may be harmful. OBJECTIVE To examine the association between parenteral nutrition during therapeutic hypothermia and clinically important outcomes. DESIGN Retrospective, population-based cohort study using the National Neonatal Research Database; propensity scores were used to create matched groups for comparison. SETTING National Health Service neonatal units in England, Scotland and Wales. PARTICIPANTS 6030 term and near-term babies, born 1/1/2010 and 31/12/2017, who received therapeutic hypothermia; 2480 babies in the matched analysis. EXPOSURE We compared babies that received any parenteral nutrition during therapeutic hypothermia with babies that did not. MAIN OUTCOME MEASURES Primary outcome: blood culture confirmed late-onset infection; secondary outcomes: treatment for late onset infection, necrotising enterocolitis, survival, length of stay, measures of breast feeding, hypoglycaemia, central line days, time to full enteral feeds, discharge weight. RESULTS 1475/6030 babies (25%) received parenteral nutrition. In comparative matched analyses, the rate of culture positive late onset infection was higher in babies that received parenteral nutrition (0.3% vs 0.9%; difference 0.6; 95% CI 0.1, 1.2; p=0.03), but treatment for presumed infection was not (difference 0.8%, 95% CI -2.1 to 3.6, p=0.61). Survival was higher in babies that received parenteral nutrition (93.1% vs 90.0%; rate difference 3.1, 95% CI 1.5, 4.7; p<0.001). CONCLUSIONS Receipt of parenteral nutrition during therapeutic hypothermia is associated with higher late-onset infection but lower mortality. This finding may be explained by residual confounding. Research should address the risks and benefits of parenteral nutrition in this population.

Abstract
OBJECTIVES The nutritional management of critically ill term neonates and preterm infants varies widely, and controversies exist in regard to when to initiate nutrition, mode of feeding, energy requirements, and composition of enteral and parenteral feeds. Recommendations for nutritional support in critical illness are needed. METHODS The ESPGHAN Committee on Nutrition (ESPGHAN-CoN) conducted a systematic literature search on nutritional support in critically ill neonates, including studies on basic metabolism. The Medline database and the Cochrane Library were used in the search for relevant publications. The quality of evidence was reviewed and discussed before voting on recommendations, and a consensus of 90% or more was required for the final approval. Important research gaps were also identified. RESULTS This position paper provides clinical recommendations on nutritional support during different phases of critical illness in preterm and term neonates based on available literature and expert opinion. CONCLUSION Basic research along with adequately powered trials are urgently needed to resolve key uncertainties on metabolism and nutrient requirements in this heterogeneous patient population.

Abstract
BACKGROUND Therapeutic hypothermia is standard of care for babies with moderate to severe hypoxic-ischaemic encephalopathy. There is limited evidence to inform provision of nutrition during hypothermia. OBJECTIVES To assess the association during therapeutic hypothermia between (1) enteral feeding and outcomes, such as necrotising enterocolitis and (2) parenteral nutrition and outcomes, such as late-onset bloodstream infection. DESIGN A retrospective cohort study using data held in the National Neonatal Research Database and applying propensity score methodology to form matched groups for analysis. SETTING NHS neonatal units in England, Wales and Scotland. PARTICIPANTS Babies born at ≥ 36 gestational weeks between 1 January 2010 and 31 December 2017 who received therapeutic hypothermia for 72 hours or who died during treatment. INTERVENTIONS Enteral feeding analysis - babies who were enterally fed during therapeutic hypothermia (intervention) compared with babies who received no enteral feeds during therapeutic hypothermia (control). Parenteral nutrition analysis - babies who received parenteral nutrition during therapeutic hypothermia (intervention) compared with babies who received no parenteral nutrition during therapeutic hypothermia (control). OUTCOME MEASURES Primary outcomes were severe and pragmatically defined necrotising enterocolitis (enteral feeding analysis) and late-onset bloodstream infection (parenteral nutrition analysis). Secondary outcomes were survival at neonatal discharge, length of neonatal stay, breastfeeding at discharge, onset of breastfeeding, time to first maternal breast milk, hypoglycaemia, number of days with a central line in situ, duration of parenteral nutrition, time to full enteral feeds and growth. RESULTS A total of 6030 babies received therapeutic hypothermia. Thirty-one per cent of babies received enteral feeds and 25% received parenteral nutrition. Seven babies (0.1%) were diagnosed with severe necrotising enterocolitis, and further comparative analyses were not conducted on this outcome. A total of 3236 babies were included in the matched enteral feeding analysis. Pragmatically defined necrotising enterocolitis was rare in both groups (0.5% vs. 1.1%) and was lower in babies who were fed during hypothermia (rate difference -0.5%, 95% confidence interval -1.0% to -0.1%; p = 0.03). Higher survival to discharge (96.0% vs. 90.8%, rate difference 5.2%, 95% confidence interval 3.9% to 6.6%; p < 0.001) and higher breastfeeding at discharge (54.6% vs. 46.7%, rate difference 8.0%, 95% confidence interval 5.1% to 10.8%; p < 0.001) rates were observed in enterally fed babies who also had a shorter neonatal stay (mean difference -2.2 days, 95% confidence interval -3.0 to -1.2 days). A total of 2480 babies were included in the matched parenteral nutrition analysis. Higher levels of late-onset bloodstream infection were seen in babies who received parenteral nutrition (0.3% vs. 0.9%, rate difference 0.6%, 95% confidence interval 0.1% to 1.2%; p = 0.03). Survival was lower in babies who did not receive parenteral nutrition (90.0% vs. 93.1%, rate difference 3.1%, 95% confidence interval 1.5% to 4.7%; p < 0.001). LIMITATIONS Propensity score methodology can address imbalances in observed confounders only. Residual confounding by unmeasured or poorly recorded variables cannot be ruled out. We did not analyse by type or volume of enteral or parenteral nutrition. CONCLUSIONS Necrotising enterocolitis is rare in babies receiving therapeutic hypothermia, and the introduction of enteral feeding is associated with a lower risk of pragmatically defined necrotising enterocolitis and other beneficial outcomes, including rates of higher survival and breastfeeding at discharge. Receipt of parenteral nutrition during therapeutic hypothermia is associated with a higher rate of late-onset infection but lower mortality. These results support introduction of enteral feeding during therapeutic hypothermia. FUTURE WORK Randomised trials to assess parenteral nutrition during therapeutic hypothermia.

Abstract
BACKGROUND Therapeutic hypothermia is standard of care in high-income countries for babies born with signs of hypoxic ischaemic encephalopathy, but optimal feeding during treatment is uncertain and practice is variable. This study aimed to assess the association between feeding during therapeutic hypothermia and clinically important outcomes. METHODS We did a population-level retrospective cohort study using the UK National Neonatal Research Database. We included all babies admitted to National Health Service neonatal units in England, Scotland, and Wales between Jan 1, 2010, and Dec 31, 2017, who received therapeutic hypothermia for 72 h or died during this period. For analysis, we created matched groups using propensity scores and compared outcomes in babies who were fed versus unfed enterally during therapeutic hypothermia. The primary outcome was severe necrotising enterocolitis, either confirmed at surgery or causing death. Secondary outcomes include pragmatically defined necrotising enterocolitis (a recorded diagnosis of necrotising enterocolitis in babies who received at least 5 consecutive days of antibiotics while also nil by mouth during their neonatal unit stay), late-onset infection (pragmatically defined as 5 consecutive days of antibiotic treatment commencing after day 3), survival to discharge, measures of breastmilk feeding, and length of stay in neonatal unit. FINDINGS 6030 babies received therapeutic hypothermia, of whom 1873 (31·1%) were fed during treatment. Seven (0·1%) babies were diagnosed with severe necrotising enterocolitis and the number was too small for further analyses. We selected 3236 (53·7%) babies for the matched feeding analysis (1618 pairs), achieving a good balance for all recorded background variables. Pragmatically defined necrotising enterocolitis was rare in both groups (incidence 0·5%, 95% CI 0·2-0·9] in the fed group vs 1·1% [0·7-1·4] in the unfed group). The enterally fed group had fewer pragmatically defined late-onset infections (difference -11·6% [95% CI -14·0 to -9·3]; p<0·0001), higher survival to discharge (5·2% [3·9-6·6]; p<0·0001), higher proportion of breastfeeding at discharge (8·0% [5·1-10·8]; p<0·0001), and shorter neonatal unit stays (-2·2 [-3·0 to -1·2] days; p<0·0001) compared with the unfed group. INTERPRETATION Necrotising enterocolitis is rare in babies receiving therapeutic hypothermia. Enteral feeding during hypothermia is safe and associated with beneficial outcomes compared with not feeding, although residual confounding could not be completely ruled out. Our findings support starting milk feeds during therapeutic hypothermia. FUNDING UK National Institute for Health Research Health Technology Assessment programme 16/79/13.

Abstract
AIM Since therapeutic hypothermia (TH) is known for its inhibitory effects on leucocyte migration and cytokine synthesis, our aim was to underline the necessity of early monitoring for potential immunomodulatory risks. METHODS Using a 13-year retrospective case-control study at the paediatric intensive care unit (PICU) of the Medical University in Vienna, all newborn infants and children receiving TH were screened and compared with a diagnosis-matched control group undergoing conventional normothermic treatment (NT). TH was accomplished by using a non-invasive cooling device. Target temperature was 32-34°C. Children with evident infections, a medical history of an immunodeficiency or undergoing immunosuppressive therapy, were excluded. RESULTS During the observational period, 108 patients were screened, 27 of which underwent TH. Culture-proven infections occurred in 22% of the TH group compared with 4% of the normothermic controls (P = .1). From the second day following PICU admission, median C-reactive protein (CRP) values were higher in the TH group (day two P = .002, day three P = .0002, day six P = .008). CONCLUSION Children undergoing TH showed earlier and higher increases in CRP levels when compared to normothermic controls. These data underline the necessity of early and continuous monitoring for possible infectious complications.

Abstract
Context Term neonates treated with therapeutic hypothermia (TH) may experience delays in acquiring skills for oral feeding, thus prolonging hospital admission. Objective To determine whether osteopathic manipulative treatment (OMT) can decrease the overall length of stay (LOS) for term neonates by accelerating the transition to full oral feeds. Methods A pilot study was conducted to compare LOS in term neonates treated with OMT to matched historical controls. Eligibility criteria were gestational age greater than or equal to 37 weeks, mild to moderate encephalopathy, absent seizure activity, and no brain injury on magnetic resonance imaging. Treated neonates had OMT twice between day of life four and seven, then twice per week on nonconsecutive days until hospital discharge. Secondary outcomes were to compare the number of days with nasogastric tube in both OMT and historically matched control groups and to characterize somatic dysfunction patterns in the primary affected areas of the craniosacral mechanism. Results Twelve of 28 neonates treated with TH between October 2017 and August 2018 met eligibility criteria for the study and were matched 3:1 to 36 historical controls. On average, mothers of neonates who received OMT were older than the historical control mothers (31.3 years [SD, ±6.0] vs. 27.4 [SD, ±4.5]; p=0.02) Nineteen of the 36 historical control neonates, but no neonates in the OMT group, were intubated for a median of two days (interquartile range 1, 4). The mean LOS in the OMT group was 9.1 vs. 11.6 days for historical controls (p=0.048); however, in a sensitivity analysis excluding intubated neonates from the historical controls, the difference was 9.1 vs. 10.1 days (p=0.21). All neonates were orally feeding at discharge. Neonates given OMT had between two and four treatments lasting 8-20 minutes. By the final treatment, the craniosacral mechanism's intraosseous and cranial base compressions and physiologic motion were improved. There were no adverse effects noted during OMT sessions. Conclusion Our findings suggest that OMT performed on term neonates treated with TH may decrease the amount of time needed to acquire the necessary skills for oral feeding. Although this result was not statistically significant, it may be clinically significant. A larger prospective clinical trial may have the power needed to detect a statistically significant reduction in LOS and number of days to full oral feeds in this patient population.

Abstract
INTRODUCTION Preterm babies are among the highest users of parenteral nutrition (PN) of any patient group, but there is wide variation in commencement, duration, and composition of PN and uncertainty around which groups will benefit from early introduction. Recent studies in critically unwell adults and children suggest that harms, specifically increased rates of nosocomial infection, outweigh the benefits of early administration of PN. In this study, we will describe early PN use in neonatal units in England, Wales and Scotland. We will also evaluate if this is associated with differences in important neonatal outcomes in neonates born between 30+0 and 32+6 weeks+days gestation. METHODS AND ANALYSIS We will use routinely collected data from all neonatal units in England, Wales and Scotland, available in the National Neonatal Research Database (NNRD). We will describe clinical practice in relation to any use of PN during the first 7 postnatal days among neonates admitted to neonatal care between 1 January 2012 and 31 December 2017. We will compare outcomes in neonates born between 30+0 and 32+6 weeks+days gestation who did or did not receive PN in the first week after birth using a propensity score-matched approach. The primary outcome will be survival to discharge home. Secondary outcomes will include components of the neonatal core outcome set: outcomes identified as important by former patients, parents, clinicians and researchers. ETHICS AND DISSEMINATION We have obtained UK National Research Ethics Committee approval for this study (Ref: 18/NI/0214). The results of this study will be presented at academic conferences; the UK charity Bliss will aid dissemination to former patients and parents. TRIAL REGISTRATION NUMBER NCT03767634.
