Abstract
Establishing enteral nutrition after the birth of preterm infants presents numerous challenges, particularly for those in special situations. Various disease factors and medical interventions impede the establishment of enteral feeding, leading to conflicts and controversies regarding feeding goals, feeding methods, and the challenges and solutions faced by these infants. A critical issue for clinical physicians is how to safely and promptly establish enteral nutrition to achieve full enteral feeding as quickly as possible. The consensus formulation working group, based on both domestic and overseas research, adopted the Grading of Recommendations Assessment, Development and Evaluation, and formed an expert consensus on enteral nutrition management for preterm infants in special situations. This consensus provides 14 recommendations for 9 common special situations, aiming to offer guidance on enteral nutrition management for preterm infants to improve their short and long-term outcomes.

Timing of Red Blood Cell Transfusions and Occurrence of Necrotizing Enterocolitis: A Secondary Analysis of a Randomized Clinical Trial. JAMA Netw Open 2024; 7:e249643. [PMID: 38700862 PMCID: PMC11069076 DOI: 10.1001/jamanetworkopen.2024.9643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 03/05/2024] [Indexed: 05/06/2024] Open
Abstract
Importance Observational studies often report that anemia and red blood cell (RBC) transfusions are associated with a higher risk of necrotizing enterocolitis (NEC) among extremely low-birthweight (ELBW) infants. Objective To evaluate whether there is a temporal association between 72-hour hazard periods of exposure to RBC transfusions and NEC among ELBW infants randomized to either higher or lower hemoglobin transfusion thresholds. Design, Setting, and Participants This post hoc secondary analysis of 1690 ELBW infants who survived to postnatal day 10 enrolled in the Transfusion of Prematures (TOP) randomized multicenter trial between December 1, 2012, and April 12, 2017, was performed between June 2021 and July 2023. Exposures First, the distribution of RBC transfusions and the occurrence of NEC up to postnatal day 60 were examined. Second, 72-hour posttransfusion periods were categorized as hazard periods and the pretransfusion periods of variable duration as control periods. Then, the risk of NEC in posttransfusion hazard periods was compared with that in pretransfusion control periods, stratifying the risk based on randomization group (higher or lower hemoglobin transfusion threshold group). Main Outcomes and Measures The primary outcome was incidence of NEC stage 2 or 3. Secondary outcomes included the incidence rates of NEC within five 10-day intervals, taking into account the number of days at risk. Results Of 1824 ELBW infants randomized during the TOP trial, 1690 were included in the present analysis (mean [SD] gestational age, 26.0 [1.5] weeks; 899 infants [53.2%] were female). After categorizing 4947 hazard periods and 5813 control periods, we identified 133 NEC cases. Fifty-nine of these cases (44.4%) occurred during hazard periods. Baseline and clinical characteristics of infants with NEC during hazard periods did not differ from those of infants with NEC during control periods. The risk of NEC was 11.9 per 1000 posttransfusion hazard periods and 12.7 per 1000 control periods (adjusted risk ratio, 0.95; 95% CI, 0.68-1.32; P = .74). This risk did not differ significantly between randomization groups, but the incidence rate of NEC per 1000 days peaked between postnatal days 20 and 29 in the lower hemoglobin transfusion threshold group. Conclusions and Relevance The findings of this post hoc analysis suggest that, among ELBW infants with the hemoglobin ranges occurring in the TOP trial, exposure to RBC transfusions was not temporally associated with a higher risk of NEC during 72-hour posttransfusion hazard periods. Given that the incidence rate of NEC peaked between postnatal days 20 and 29 among infants with lower hemoglobin values, a more in-depth examination of this at-risk period using larger data sets is warranted. Trial Registration ClinicalTrials.gov Identifier: NCT01702805.

Abstract
Necrotizing enterocolitis (NEC) is a leading cause of morbidity and mortality in preterm infants. Severe anemia and red blood cell (RBC) transfusion are associated with gut inflammation and injury in preclinical models and observational studies. However, there is uncertainty about the causal role of these factors in the pathogenesis of NEC. Observational studies have shown that withholding feeding during RBC transfusion may reduce the risk of NEC, although confirmatory data from randomized trials are lacking. In this review, we summarize data on feeding during RBC transfusion and its role in NEC and highlight ongoing randomized trials.

Abstract
Establishing full enteral nutrition in critically ill preterm infants with immature gastrointestinal function is challenging. In this article, we will summarize emerging clinical evidence from randomized clinical trials suggesting the feasibility and efficacy of feeding interventions targeting the early establishment of full enteral nutrition. We will also examine trial outcomes of higher volume feedings after the establishment of full enteral nutrition. Only data from randomized clinical trials will be discussed extensively. Future opportunities for clinical research will also be presented.

Abstract
Patient blood management (PBM) strategies are needed in the neonate and paediatric population, given that haemoglobin thresholds used are often higher than recommended by evidence, with exposure of children to potential complications without meaningful benefit. A literature review was performed on the following topics: evidence-based transfusions of blood components and pharmaceutical agents. Other topics reviewed included perioperative coagulation assessment and perioperative PBM. The Transfusion and Anaemia Expertise Initiative (TAXI) consortium published a consensus statement addressing haemoglobin (Hb) transfusion threshold in multiple subsets of patients. A multicentre trial (PlaNeT-2) reported a higher risk of bleeding and death or serious new bleeding among infants who received platelet transfusion at a higher (50 000/μl) compared to a lower (25 000/μl) threshold. Recent data support the use of a restrictive transfusion threshold of 25 000/μl for prophylactic platelet transfusions in preterm neonates. The TAXI-CAB consortium mentioned that in critically ill paediatric patients undergoing invasive procedures outside of the operating room, platelet transfusion might be considered when the platelet count is less than or equal to 20 000/μl and there is no benefit of platelet transfusion when the platelet count is more than 50 000/μl. There are limited controlled studies in paediatric and neonatal population regarding plasma transfusion. Blood conservation strategies to minimise allogenic blood exposure are essential to positive patient outcomes neonatal and paediatric transfusion practices have changed significantly in recent years since randomised controlled trials were published to guide practice. Additional studies are needed in order to provide practice change recommendations.

Feeding Strategies in Preterm Very Low Birth-Weight Infants: State-of-the-Science Review. Adv Neonatal Care 2021; 21:493-502.

Abstract
BACKGROUND Providing enteral feeds to preterm very low birth-weight (VLBW) infants is critical to optimize nutrition, enhance growth, and reduce complications. Protocols guiding feeding practices can improve outcomes, but significant variation exists between institutions, which may limit their utility. To be most effective, protocols should be based on the best available evidence. PURPOSE To examine the state of the science on several key components of feeding protocols for VLBW infants. SEARCH STRATEGY The authors searched PubMed, CINAHL, and EMBASE databases for terms related to feeding VLBW infants less than 32 weeks' gestational age, including initiation of feedings, rate of feeding advancement, timing of human milk (HM) fortification, and feeding during blood transfusions, when diagnosed with a patent ductus arteriosus (PDA) and during medical treatment of PDA closure. RESULTS Initiation of feeds within the first 3 days of life and advancement by 30 mL/kg/d may decrease time to attain full feeds without increasing complications. Insufficient evidence guides optimal timing of HM fortification, as well as feeding infants undergoing blood transfusions, infants diagnosed with a PDA, and infants receiving medical treatment of PDA closure. IMPLICATIONS FOR PRACTICE Integration of existing research regarding feeding initiation and advancement into feeding protocols may improve outcomes. Infants at highest risk of feeding-related complications may benefit from a personalized feeding approach. IMPLICATIONS FOR RESEARCH Additional research is needed to provide evidence concerning the optimal timing of HM fortification and feeding strategies for infants undergoing blood transfusions and those diagnosed with a PDA or receiving medical treatment of PDA closure to incorporate into evidence-based feeding protocols.

Abstract
BACKGROUND Red blood cell (RBC) transfusions have been implicated in the development of necrotizing enterocolitis (NEC) in premature infants. Some evidence exists to support that withholding feedings during transfusion reduces the risk of subsequent NEC development. PURPOSE To review the most recent literature on this topic to determine best evidence-based practice regarding withholding or not withholding feedings during RBC transfusions. METHODS/SEARCH STRATEGY Four databases were searched using keywords and MeSH terms including "necrotizing enterocolitis," "NEC," "NPO," and "transfusion," with specifications limiting the search to articles published in the last 10 years and limiting the population to neonates. FINDINGS Four studies did not demonstrate a reduction in transfusion-associated necrotizing enterocolitis (TANEC) with the implementation of feeding protocols during packed red blood cell (PRBC) transfusions. One study concluded that it could not confirm the benefit of withholding feeds during transfusion to reduce the risk of TANEC. A 2020 randomized controlled trial (RCT) found no difference in splanchnic oxygenation when enteral feeds are withheld, continued, or restricted during a PRBC transfusion. Holding feedings during PRBC transfusions did not result in adverse nutritional outcomes. IMPLICATIONS FOR PRACTICE To determine best evidence-based practice surrounding feeding protocols during RBC transfusions in very low-birth-weight and premature infants less than 37 weeks' gestation. IMPLICATIONS FOR RESEARCH It is recommended that large, multicentered, adequately powered RCTs be conducted in this area. Individual institutions should standardize their practice to improve quality, safety, and patient outcomes.

Abstract
Fortification refers to the practice of enriching human milk feeds for very preterm babies with macronutrients, minerals and vitamins. Though standard of care in some parts of the world, adoption of fortification is not universal. Fortification entered into use on the assumption that human milk macronutrient content, principally protein, is insufficient to support the growth and development of very preterm babies. However, because of the substantial variability in human milk composition, routine fortification risks exposing some babies to very high protein intakes, which may be dangerous. Some clinicians fear fortification with cow-milk derived products will increase the risk of necrotising enterocolitis, leading them to favour commercial fortifiers made from pooled human milk over cow milk based products, a practice that has additional ethical implications. Randomised controlled trials of multi-nutrient fortification to-date are inadequate. No trial has had power to detect important functional effects; the majority are methodologically weak and focus primarily upon short-term growth. Evidence to guide practice is inadequate. There is an urgent need for collaboration to conduct high-quality research to end these long-standing uncertainties.

Abstract
BACKGROUND More effective recruitment strategies like alternative approaches to consent are needed to facilitate adequately powered trials. Witholding Enteral feeds Around Transfusion was a multicentre, randomised, pilot trial that compared withholding and continuing feeds around transfusion. The primary clinical outcome was necrotising enterocolitis. The trial used simplified opt-out consent with concise parent information and no consent form. OBJECTIVE To explore the views and experiences of parents and health professionals on the acceptability and feasibility of opt-out consent in randomised comparative effectiveness trials. METHODS A qualitative, descriptive interview-based study nested within a randomised trial. Semistructured interview transcripts were analysed using inductive thematic analysis. SETTING Eleven neonatal units in England. PARTICIPANTS Eleven parents and ten health professionals with experience of simplified consent. RESULTS Five themes emerged: 'opt-out consent operationalised as verbal opt-in consent', 'opt-out consent normalises participation while preserving parental choice', 'opt-out consent as an ongoing process of informed choice', 'consent without a consent form' and 'choosing to opt out of a comparative effectiveness trial', with two subthemes: 'wanting "normal care"' and 'a belief that feeding is better'. CONCLUSION Introducing a novel form of consent proved challenging in practice. The principle of a simplified, opt-out approach to consent was generally considered feasible and acceptable by health professionals for a neonatal comparative effectiveness trial. The priority for parents was having the right to decide about trial participation, and they did not see opt-out consent as undermining this. Describing a study as 'opt-out' can help to normalise participation and emphasise that parents can withdraw consent.

Abstract
OBJECTIVE To compare the characteristics and short-term outcomes in extremely preterm infants, who developed necrotizing enterocolitis (NEC) following a packed red blood cell transfusion (pRBC) within 48 h (TANEC), with those who developed NEC beyond 48 h (non-TANEC). SETTING A single-center retrospective cohort study in a Tertiary neonatal intensive care unit in the UK over a 5-year period. PATIENTS AND METHODS Extremely premature infants (23-27 weeks gestation) were selected. TANEC and non-TANEC incidence were calculated from the confirmed NEC group (defined as modified Bell's stage II and beyond). The characteristics and short-term outcomes of infants with TANEC in the first 8 weeks of life were compared to infants with non-TANEC. RESULTS AND INTERPRETATION Incidence of confirmed NEC was 14% (28/207). On further subgroup analysis of the confirmed NEC cases, 46% (13/28) of infants were identified with TANEC and 54% (15/28) with non-TANEC. The incidence of TANEC did not correlate with the number of antecedent pRBC transfusions or the pre-transfusion median hemoglobin (Hb) levels. There were no significant differences in characteristics between the TANEC and non-TANEC groups. Infants within the TANEC group required more intensive neonatal care support, greater surgical intervention (p-value 0.043) with loss of gut integrity and an increase in number of TPN dependency days (p-value 0.014). CONCLUSIONS A significantly worse clinical course and short-term outcome was observed in the TANEC group when compared with the non-TANEC group.

Traditionally, the uncertainty in decision making was handled using expertise collected by individual providers and, more recently, systematic appraisal of research in the form of evidence-based medicine. The traditional approach has been used successfully in medicine for a very long time. However, it has substantial limitations because of the complexity of the system of the human body and healthcare. The complex systems are a network of highly coupled components intensely interacting with each other. These interactions give those systems redundancy and thus robustness to failure and, at the same time, equifinality, that is, many different causative pathways leading to the same outcome. The equifinality of the complex systems of the human body and healthcare system demand the individualization of medical care, medicine, and medical decision making. Computational models excel in modeling complex systems and, consequently, enabling individualization of medical decision making and medicine. Computational models are theory- or knowledge-based models, data-driven models, or models that combine both approaches. Data are essential, although to a different degree, for computational models to successfully represent complex systems. The individualized decision making, made possible by the computational modeling of complex systems, has the potential to revolutionize the entire spectrum of medicine from individual patient care to policymaking. This approach allows applying tests and treatments to individuals who receive a net benefit from them, for whom benefits outweigh the risk, rather than treating all individuals in a population because, on average, the population benefits. Thus, the computational modeling-enabled individualization of medical decision making has the potential to both improve health outcomes and decrease the costs of healthcare.

Abstract
Every clinician is aware of the many uncertainties that exist in everyday clinical care. These contribute to variation and inequity in outcomes and pose dangers to patient wellbeing and safety. Evidence generation is still too slow, too expensive, too much left to chance, too ad hoc, and wholly inadequate. Modern technologies can drive faster, more efficient evidence generation and implementation of findings. However, professional and public buy-in are also needed for success; in short, a new conceptual framework aimed at reducing uncertainties effectively, efficiently, and incrementally in clinical practice is required. Currently, much-needed research to reduce practice uncertainties is often never done, or conducted in ways that are inefficient or lack impact. The consequence is poor patient care and abrogation of the cardinal duty of doctors to "first, do no harm." Research is efficient if high quality, conducted rapidly, at reasonable cost, with minimal burden on investigators and participants. Research has impact if outcomes are incorporated into evidence syntheses, and robust conclusions are implemented into practice without delay. Here, I will discuss ways that build upon modern thinking and new technologies to improve the efficiency and impact of clinical research.

Jawad S, Modi N, Prevost AT, Gale C. A systematic review identifying common data items in neonatal trials and assessing their completeness in routinely recorded United Kingdom national neonatal data. Trials 2019; 20:731. [PMID: 31842960 PMCID: PMC6915866 DOI: 10.1186/s13063-019-3849-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Accepted: 10/25/2019] [Indexed: 01/04/2023] Open
Abstract
Background We aimed to test whether a common set of key data items reported across high-impact neonatal clinical trials could be identified, and to quantify their completeness in routinely recorded United Kingdom neonatal data held in the National Neonatal Research Database (NNRD). Methods We systematically reviewed neonatal clinical trials published in four high-impact medical journals over 10 years (2006–2015) and extracted baseline characteristics, stratification items and potential confounders used to adjust primary outcomes. Completeness was examined using data held in the NNRD for identified data items, for infants admitted to neonatal units in 2015. The NNRD is a repository of routinely recorded data extracted from neonatal Electronic Patient Records (EPR) of all admissions to National Health Service (NHS) Neonatal Units in England, Wales and Scotland. We defined missing data as an empty field or an implausible value. We reported common data items as frequencies and percentages alongside percentages of completeness. Results We identified 44 studies involving 32,095 infants and 126 data items. Fourteen data items were reported by more than 20% of studies. Gestational age (95%), sex (93%) and birth weight (91%) were the most common baseline data items. The completeness of data in the NNRD was high for these data with greater than 90% completeness found for 9 of the 14 most common items. Conclusion High-impact neonatal clinical trials share common data items. In the United Kingdom, these items can be obtained at a high level of completeness from routinely recorded data held in the NNRD. The feasibility and efficiency using routinely recorded EPR data, such as that held in the NNRD, for clinical trials, rather than collecting these items anew, should be examined. Trial registration PROSPERO registration number CRD42016046138. Registered prospectively on 17 August 2016.
