Abstract
Introduction This article reviews the evidence for the use of different strains of probiotics in the prevention of prevalent pathologies in premature neonates. A systematic review was conducted of the use of probiotics in neonates with less than 37 weeks of gestational age, based on a search for systematic reviews and observational and experimental studies performed during the period from January 2014 to February 2021. For this purpose, the PubMed, MEDLINE and Cochrane Library databases were consulted. The aim of this article was to review the existing data on the relationship between the administration of probiotics (with different strains and doses) and the risk of necrotising enterocolitis, mortality, late sepsis and other disease parameters in premature infants. The literature search obtained 240 articles, of which we selected 16, representing a total sample of over 200,000 premature infants. Analysis of the data obtained reveals statistical evidence that the combined administration of probiotics (especially of Lactobacillus and Bifidobacterium strains) reduces the incidence of grade II or higher necrotising enterocolitis, all-cause mortality, late sepsis, length of hospital stay and time until complete enteral nutrition is achieved. However, no benefits were apparent with respect to alleviating bronchopulmonary dysplasia, retinopathy of prematurity or intraventricular haemorrhage. Further research is needed to determine the most appropriate strains, doses and treatment duration for preterm infants to achieve the health benefits identified.

Probiotic supplementation and risk of necrotizing enterocolitis and mortality among extremely preterm infants-the Probiotics in Extreme Prematurity in Scandinavia (PEPS) trial: study protocol for a multicenter, double-blinded, placebo-controlled, and registry-based randomized controlled trial. Trials 2024; 25:259.

Abstract
BACKGROUND Extremely preterm infants, defined as those born before 28 weeks' gestational age, are a very vulnerable patient group at high risk for adverse outcomes, such as necrotizing enterocolitis and death. Necrotizing enterocolitis is an inflammatory gastrointestinal disease with high incidence in this cohort and has severe implications on morbidity and mortality. Previous randomized controlled trials have shown reduced incidence of necrotizing enterocolitis among older preterm infants following probiotic supplementation. However, these trials were underpowered for extremely preterm infants, rendering evidence for probiotic supplementation in this population insufficient to date. METHODS The Probiotics in Extreme Prematurity in Scandinavia (PEPS) trial is a multicenter, double-blinded, placebo-controlled and registry-based randomized controlled trial conducted among extremely preterm infants (n = 1620) born at six tertiary neonatal units in Sweden and four units in Denmark. Enrolled infants will be allocated to receive either probiotic supplementation with ProPrems® (Bifidobacterium infantis, Bifidobacterium lactis, and Streptococcus thermophilus) diluted in 3 mL breastmilk or placebo (0.5 g maltodextrin powder) diluted in 3 mL breastmilk per day until gestational week 34. The primary composite outcome is incidence of necrotizing enterocolitis and/or mortality. Secondary outcomes include incidence of late-onset sepsis, length of hospitalization, use of antibiotics, feeding tolerance, growth, and body composition at age of full-term and 3 months corrected age after hospital discharge. DISCUSSION Current recommendations for probiotic supplementation in Sweden and Denmark do not include extremely preterm infants due to lack of evidence in this population. However, this young subgroup is notably the most at risk for experiencing adverse outcomes. This trial aims to investigate the effects of probiotic supplementation on necrotizing enterocolitis, death, and other relevant outcomes to provide sufficiently powered, high-quality evidence to inform probiotic supplementation guidelines in this population. The results could have implications for clinical practice both in Sweden and Denmark and worldwide. TRIAL REGISTRATION ( Clinicaltrials.gov ): NCT05604846.

Abstract
Although necrotizing enterocolitis is a leading cause of morbidity and mortality among preterm infants, its underlying pathophysiology is not fully understood. Gut dysbiosis, an imbalance between commensal and pathogenic microbes, in the preterm infant is likely a major contributor to the development of necrotizing enterocolitis. In this review, we will discuss the increasing use of probiotics in the NICU, an intervention aimed to mitigate alterations in the gut microbiome. We will review the existing evidence regarding the safety and effectiveness of probiotics, and their potential to reduce rates of necrotizing enterocolitis in preterm infants.

Abstract
Neurological symptoms and signs of Coronavirus disease-19 (COVID-19) can accompany, follow, or precede respiratory symptoms and signs; hence, they are important in the diagnosis and management of COVID-19 patients. In this retrospective study conducted during the second wave of COVID-19, we included all patients diagnosed with COVID-19 using real-time polymerase chain reaction and admitted to the Tribhuvan University Teaching Hospital between June 2021 and October 2021. The patients were categorized into 2 groups: group A (with neurological manifestations or complications) and Group-B (without neurological manifestations or complications). The 2 groups were compared in terms of intensive care unit (ICU) admission, need for ventilatory support, length of hospital stay, and various outcomes. The study included 235 participants ranging in age from 13 to 102 years (mean age = 54 years, standard deviation = 18). Among the participants, 54.50% were male. The proportion of individuals in group A was higher (59.15%, N = 139) than that in Group-B (40.85%, N = 96). Notably, a significantly greater number of patients were admitted to the ICU in Group B than in Group A. However, there were no statistically significant differences in the need for ventilatory support or hospital stay between the 2 groups. Interestingly, group A showed a higher rate of improvement (Z = -3.1145, P = .00188, 95% CI), while Group-B had a higher rate of mortality (Z = 4.5562, P < .00001, 95% CI). Altered mental status and stroke have been specifically linked to poorer outcomes, whereas typical neurological manifestations, such as hyposmia, hypogeusia, dizziness, headache, and myalgia, are associated with better outcomes.

Abstract
Objectives Neonatal necrotizing enterocolitis (NEC) is a severe gastrointestinal disease that primarily affects preterm and very low birth weight infants, with high morbidity and mortality. We aim to build a reliable prediction model to predict the risk of NEC in preterm and very low birth weight infants. Methods We conducted a retrospective analysis of medical data from infants (gestational age <32 weeks, birth weight <1,500 g) admitted to Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region. We collected clinical data, randomly dividing it into an 8:2 ratio for training and testing. Multivariate logistic regression was employed to identify significant predictors for NEC. Principal component analysis was used for dimensionality reduction of numerical variables. The prediction model was constructed through logistic regression, incorporating all relevant variables. Subsequently, we calculated performance evaluation metrics, including Receiver Operating Characteristic (ROC) curves and confusion matrices. Additionally, we conducted model performance comparisons with common machine learning models to establish its superiority. Results A total of 292 infants were included, with 20% (n = 58) randomly selected for external validation. Multivariate logistic regression revealed the significance of four predictors for NEC in preterm and very low birth weight infants: temperature (P = 0.003), Apgar score at 5 min (P = 0.004), formula feeding (P = 0.007), and gestational diabetes mellitus (GDM, P = 0.033). The model achieved an accuracy of 82.46% in the test set with an F1 score of 0.90, outperforming other machine learning models (support vector machine, random forest). Conclusions Our logistic regression model effectively predicts NEC risk in preterm and very low birth weight infants, as confirmed by external validation. Key predictors include temperature, Apgar score at 5 min, formula feeding, and GDM. This study provides a vital tool for NEC risk assessment in this population, potentially improving early interventions and child survival. However, clinical validation and further research are necessary for practical application.

Abstract
OBJECTIVE To evaluate the effects of guideline-driven prophylactic supplementation of a multi-strain neonatal intensive care unit-specific probiotic product on infants born very preterm (VP) or very low birth weight (VLBW). STUDY DESIGN A prospective cohort of 125 infants born in one year after implementation who received probiotics were compared to a retrospective cohort of eligible 126 VP or VLBW infants who did not receive probiotics. The primary outcome of interest was necrotizing enterocolitis (NEC). RESULT The incidence of NEC decreased from 6.3 to 1.6%. After adjusting for multiple variables, there were no significant differences in primary or other outcomes of interest; odds ratio (95% confidence interval) NEC 0.27 (0.05-1.33), death 0.76 (0.26-2.21) and late-onset sepsis 0.54 (0.18-1.63). No adverse effects related to probiotics supplementation were observed. CONCLUSION Although nonsignificant, prophylactic probiotics supplementation in infants born VP or VLBW was associated with reduction of NEC.

Abstract
Necrotizing enterocolitis (NEC) is a life-threatening disease that predominantly affects very low birth weight preterm infants. Development of NEC in preterm infants is accompanied by high mortality. Surgical treatment of NEC can be complicated by short bowel syndrome, intestinal failure, parenteral nutrition-associated liver disease, and neurodevelopmental delay. Issues surrounding pathogenesis, prevention, and treatment of NEC remain unclear. This review summarizes data on prenatal risk factors for NEC, the role of pre-eclampsia, and intrauterine growth retardation in the pathogenesis of NEC. The role of hypoxia in NEC is discussed. Recent data on the role of the intestinal microbiome in the development of NEC, and features of the metabolome that can serve as potential biomarkers, are presented. The Pseudomonadota phylum is known to be associated with NEC in preterm neonates, and the role of other bacteria and their metabolites in NEC pathogenesis is also discussed. The most promising approaches for preventing and treating NEC are summarized.

Abstract
PURPOSE To determine what modifiable interventions used in the neonatal intensive care unit (NICU) are associated with severe necrotizing enterocolitis (NEC) requiring surgical intervention. METHODS A retrospective review of patients treated for NEC at a tertiary hospital from 1991 to 2016 was performed. Patient characteristics were used to calculate propensity scores for likelihood of exposure to seven interventions: enteral feeds, use of glucocorticoids, nonsteroidal anti-inflammatory drugs (NSAIDs), antacids, antibiotics, or umbilical arterial (UAC) and venous catheters (UVC). Conditional logistic regression was used to compare the odds of having surgical NEC if exposed to each treatment. RESULTS We included 195 NEC patients: 69 severe NEC managed with surgery and 126 non-severe NEC managed medically. After propensity score matching based on birth characteristics, exposure to glucocorticoids (OR 5.21, 95%CI: 1.62, 16.70), NSAIDs (OR 4.87, 95%CI: 1.67, 14.17), UVC (OR 2.53 (95%CI: 1.19, 5.73), and UAC (OR 4.91, 95%CI: 2.12, 11.37) were associated with surgical NEC in separate conditional logistic regression analyses. Including these treatments in a second round of propensity matching and conditional logistic regression revealed that glucocorticoids (OR 2.99, 95%CI: 1.01, 8.88), NSAIDs (OR 3.97, 95%CI: 1.41, 11.19), UVC (OR 3.07, 95%CI: 1.46, 6.48), and UAC (OR 5.10, 95%CI: 2.10, 12.36) were still associated with surgical NEC. CONCLUSION After controlling for birth confounders and common NICU supportive interventions, use of glucocorticoids, NSAIDs and umbilical catheters independently increased the odds of developing severe NEC requiring surgical intervention. LEVEL-OF-EVIDENCE RATING Case-control, Level III evidence.

Abstract
OBJECTIVE Prompted by an acute increase in necrotizing enterocolitis (NEC) rates, we aimed to decrease the rate of stage 2 or greater NEC in infants born at <1500 grams or <30 weeks gestational age from 19.5% to less than 9.7% (a 50% reduction) within 18 months, without adversely affecting central line-associated bloodstream infection (CLABSI) rates. STUDY DESIGN We utilized Define, Measure, Analyze, Improve, and Control (DMAIC) as our improvement model. Informed by our key driver diagram and root cause analyses, six Plan-Do-Study-Act cycles were completed. RESULTS 147 infants in the QI initiative had a median gestational age of 28.1 weeks and a median birthweight of 1070 grams. NEC rates decreased from the QI baseline of 19.5% to 6% (p = 0.03). Oral care administration increased, and maximal gavage tube dwell time decreased. CONCLUSION NEC rates decreased during this QI initiative through a combination of multidisciplinary interventions aimed at reducing dysbiosis.

Abstract
A systematic review of the PubMed and EMBASE databases was carried out to determine if time from diagnosis to surgery affects outcomes in necrotising enterocolitis. The study was registered on the PROSPERO website. Studies reporting both time to surgery and at least one clinical outcome measure in infants undergoing surgery for NEC were included. The initial search returned 1121 articles. After removing duplicates, title, and abstract screening, 49 remained for full-text review. Of these, only two reported both timing of surgery for NEC and at least one clinical outcome. The total number of neonates included was 202. Outcomes reported were death and/or parenteral nutrition use 28 days post surgery in one study and white matter brain injury in the other. No statistically significant association was found between any of the outcomes reported and timing of surgery. There were, however, significant differences associated with non-modifiable risk factors, such as age and gestation, at presentation. However, very few studies report this as a variable. Given the continuing poor outcomes and heterogeneous nature of NEC and its treatments, further large-scale prospective studies are required to examine the impact of timing of surgery, alongside other, potentially modifiable factors on outcome in NEC.

Abstract
OBJECTIVES To investigate the risk factors for necrotizing enterocolitis (NEC) in preterm infants, and to establish a scoring model that can predict the development and guide the prevention of NEC. METHODS A retrospective analysis was performed on the medical data of preterm infants who were admitted to the Department of Neonatology,Bethune First Hospital of Jilin University, from January 2011 to December 2020. These infants were divided into two groups: NEC (298 infants with Bell II stage or above) and non-NEC (300 infants). Univariate and multivariate analyses were performed to identify the factors influencing the development of NEC. A nomogram for predicting the risk of NEC was established based on the factors. The receiver operator characteristic (ROC) curve and the index of concordance (C-index) were used to evaluate the predictive performance of the nomogram. RESULTS The multivariate logistic regression analysis showed that grade ≥2 intracranial hemorrhage, peripherally inserted central catheterization, breast milk fortifier, transfusion of red cell suspension, hematocrit >49.65%, mean corpuscular volume >114.35 fL, and mean platelet volume >10.95 fL were independent risk factors for NEC (P<0.05), while the use of pulmonary surfactant, the use of probiotics, and the platelet distribution width >11.8 fL were protective factors against NEC (P<0.05). The nomogram showed good accuracy in predicting the risk of NEC, with a bootstrap-corrected C-index of 0.844. The nomogram had an optimal cutoff value of 171.02 in predicting the presence or absence of NEC, with a sensitivity of 74.7% and a specificity of 80.5%. CONCLUSIONS The prediction nomogram for the risk of NEC has a certain clinical value in early prediction, targeted prevention, and early intervention of NEC.

A Systematic Review of the Literature. Front Pediatr 2022; 10:874976. [PMID: 35656377 PMCID: PMC9152085 DOI: 10.3389/fped.2022.874976] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Accepted: 04/25/2022] [Indexed: 12/23/2022] Open
Abstract
Necrotizing enterocolitis (NEC) is a serious condition related to prematurity and the initiation of enteral feeding. In this article, we review the evidence published in recent years on necrotizing enterocolitis risk factors (prematurity, feeding with low-weight formula, existence of intestinal dysbiosis) and protective factors (human milk or donated milk supply, supplementation of human milk with oligosaccharides, probiotics administration, and the determination of disease predictive biomarkers). A systematic review was conducted of preventive, risk and predictive factors for necrotizing enterocolitis in neonates prior to 37 weeks' gestational age, based on a literature search for clinical trials, meta-analyses, randomized controlled trials and systematic reviews published between January 2018 and October 2021. For this purpose, the PubMed, MEDLINE, and Cochrane Library databases were consulted. The literature search obtained 113 articles, of which 19 were selected for further analysis after applying the inclusion and exclusion criteria. The conclusions drawn from this analysis were that adequate knowledge of risk factors that can be prevented or modified (such as alteration of the intestinal microbiota, oxidative stress, metabolic dysfunction at birth, or alteration of the immunity modulation) can reduce the incidence of NEC in premature infants. These factors include the supplementation of enteral nutrition with human milk oligosaccharides (with prebiotic and immunomodulatory effects), the combined administration of probiotics (especially the Lactobacillus spp and Bifidobacterium spp combination, which inhibits bacterial adhesion effects, improves the intestinal mucosa barrier function, strengthens the innate and adaptive immune system and increases the secretion of bioactive metabolites), the supplementation of human milk with lactoferrin and the use of donated milk fortified in accordance with the characteristics of the premature newborn. The determination of factors that can predict the existence of NEC, such as fecal calprotectin, increased TLR4 activity, and IL6 receptor, can lead to an early diagnosis of NEC. Although further studies should be conducted to determine the values of predictive biomarkers of NEC, and/or the recommended doses and strains of probiotics, lactoferrin or oligosaccharides, the knowledge acquired in recent years is encouraging.

Abstract
BACKGROUND Fetal and neonatal exposure to antibiotics may contribute to the development of necrotizing enterocolitis (NEC) in preterm infants. This systematic review and meta-analysis investigate whether exposure to third trimester maternal antibiotics (MAB) and/or prolongation of empirical antibiotics (PEAB) are associated with NEC development in preterms. METHOD We included observational and randomized controlled studies, including those on preterm or very low birth weight (VLBW) infants, from MEDLINE and EMBASE, published between 1990 and June 2021. Exposure was defined as third trimester MAB and/or PEAB. The two reviewers independently performed study selection, data extraction, and quality assessment. RESULTS Three cohort studies compared third trimester MAB with no antibiotics. MAB was associated with lower NEC incidence, unadjusted pooled odds ratio (OR) is 0.57 (95% CI: 0.35-0.93). Twelve cohort studies showed that PEAB was associated with an increased risk of NEC. Ten observational cohort studies show an unadjusted OR of 2.72 (1.65-4.47), and two case-control studies show an unadjusted mean difference of 2.31 (0.94-3.68). Moderate to substantial heterogeneity was observed but decreased in studies with low risk of bias and large sample size. CONCLUSION Evidence suggests an association between MAB and decreased risk of NEC and an association between PEAB and increased risk of NEC. Further studies should confirm these associations and explore causality. SYSTEMATIC REVIEW REGISTRATION identifier [CRD42022304937].

Abstract
Necrotizing enterocolitis (NEC), which is characterized by severe intestinal inflammation and in advanced stages necrosis, is a gastrointestinal emergency in the neonate with high mortality and morbidity. Despite advancing medical care, effective prevention strategies remain sparse. Factors contributing to the complex pathogenesis of NEC include immaturity of the intestinal immune defense, barrier function, motility and local circulatory regulation and abnormal microbial colonization. Interestingly, enteral feeding is regarded as an important modifiable factor influencing NEC pathogenesis. Moreover, breast milk, which forms the currently most effective prevention strategy, contains many bioactive components that are known to support neonatal immune development and promote healthy gut colonization. This systematic review describes the effect of different enteral feeding interventions on the prevention of NEC incidence and severity and the effect on pathophysiological mechanisms of NEC, in both experimental NEC models and clinical NEC. Besides, pathophysiological mechanisms involved in human NEC development are briefly described to give context for the findings of altered pathophysiological mechanisms of NEC by enteral feeding interventions.

Abstract
Germinal matrix-intraventricular hemorrhage (GM-IVH) is a common intracranial complication in preterm infants, especially those born before 32 weeks of gestation and very-low-birth-weight infants. Hemorrhage originates in the fragile capillary network of the subependymal germinal matrix of the developing brain and may disrupt the ependymal lining and progress into the lateral cerebral ventricle. GM-IVH is associated with increased mortality and abnormal neurodevelopmental outcomes such as posthemorrhagic hydrocephalus, cerebral palsy, epilepsy, severe cognitive impairment, and visual and hearing impairment. Most affected neonates are asymptomatic, and thus, diagnosis is usually made using real-time transfontanellar ultrasound. The present review provides a synopsis of the pathogenesis, grading, incidence, risk factors, and diagnosis of GM-IVH in preterm neonates. We explore brief literature related to outcomes, management interventions, and pharmacological and nonpharmacological prevention strategies for GM-IVH and posthemorrhagic hydrocephalus.

Abstract
Necrotizing enterocolitis (NEC) is an inflammatory bowel disease and a leading cause of morbidity and mortality in preterm infants. In this study, a randomized double-blind parallel-group (1:1) trial was carried out in two neonatal intensive care units of two tertiary hospitals. Two hundred and twenty-five preterm newborns with an expected functional gastrointestinal tract were recruited and received an enteral dose of 75 mg of docosahexaenoic acid (DHA)/kg body weight or high-oleic sunflower oil daily for 14 days from the first enteral feed after birth. Confirmed NEC was evaluated with Bell’s scale from stage ≥ IIa. Two hundred and fourteen randomized infants were analyzed in terms of the intent-to-treat (DHA-group: n = 105; control-group: n = 109); data for two hundred infants were analysed per protocol. Confirmed NEC was lower in infants from the DHA-group compared with the control-group (0/100 vs. 7/100; p = 0.007), with RR = 0.93 (95% CI 0.881 to 0.981), risk difference = −7%, (95% CI −12.00 to −1.99), and number needed-to-treat = 15 (95% CI 8.3 to 50). Intent-to-treat analysis showed a lower level of treatment failure in the DHA-group compared with the control-group (6/105 (6%) vs. 16/109 (15%); p = 0.03, RR = 0.905, (95% CI 0.826 to 0.991)). The results after multivariate-regression analysis remained significant. Adverse events (apart from the incidence of NEC) were not different between groups. A daily dose of DHA for 14 days starting with the first enteral feed may prevent NEC in preterm infants.

Abstract
Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of neonates, especially of preterm infants, with high morbidity and mortality. The surviving infants may have digestive tract and neurological sequelae. Therefore, the prevention and treatment of NEC are of great significance in improving survival rate and survival quality of neonates. To provide evidence-based recommendations for management of NEC, the guidelines were developed based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and the current domestic and overseas studies.

Abstract
Necrotizing enterocolitis (NEC), the first cause of short bowel syndrome (SBS) in the neonate, is a serious neonatal gastrointestinal disease with an incidence of up to 11% in preterm newborns less than 1500 g of birth weight. The rate of severe NEC requiring surgery remains high, and it is estimated between 20–50%. Newborns who develop SBS need prolonged parenteral nutrition (PN), experience nutrient deficiency, failure to thrive and are at risk of neurodevelopmental impairment. Prevention of NEC is therefore mandatory to avoid SBS and its associated morbidities. In this regard, nutritional practices seem to play a key role in early life. Individualized medical and surgical therapies, as well as intestinal rehabilitation programs, are fundamental in the achievement of enteral autonomy in infants with acquired SBS. In this descriptive review, we describe the most recent evidence on nutritional practices to prevent NEC, the available tools to early detect it, the surgical management to limit bowel resection and the best nutrition to sustain growth and intestinal function.

Abstract
BACKGROUND Breastfeeding has positive impacts on the health, environment, and economic wealth of families and countries. The World Health Organization (WHO) launched the Baby Friendly Hospital Initiative (BFHI) in 1991 as a global program to incentivize maternity services to implement the Ten Steps to Successful Breastfeeding (Ten Steps). These were developed to ensure that maternity services remove barriers for mothers and families to successfully initiate breastfeeding and to continue breastfeeding through referral to community support after hospital discharge. While more than three in four births in Australia take place in public hospitals, in 2020 only 26% of Australian hospitals were BFHI-accredited. So what is the social return to investing in BFHI accreditation in Australia, and does it incentivize BFHI accreditation? This study aimed to examine the social value of maintaining the BFHI accreditation in one public maternity unit in Australia using the Social Return on Investment (SROI) framework. This novel method was developed in 2000 and measures social, environmental and economic outcomes of change using monetary values. METHOD The study was non-experimental and was conducted in the maternity unit of Calvary Public Hospital, Canberra, an Australian BFHI-accredited public hospital with around 1000 births annually. This facility provided an opportunity to illustrate costs for maintaining BFHI accreditation in a relatively affluent urban population. Stakeholders considered within scope of the study were the mother-baby dyad and the maternity facility. We interviewed the hospital's Director of Maternity Services and the Clinical Midwifery Educator, guided by a structured questionnaire, which examined the cost (financial, time and other resources) and benefits of each of the Ten Steps. Analysis was informed by the Social Return on Investment (SROI) framework, which consists of mapping the stakeholders, identifying and valuing outcomes, establishing impact, calculating the ratio and conducting sensitivity analysis. This information was supplemented with micro costing studies from the literature that measure the benefits of the BFHI. RESULTS The social return from the BFHI in this facility was calculated to be AU$ 1,375,050. The total investment required was AU$ 24,433 per year. Therefore, the SROI ratio was approximately AU$ 55:1 (sensitivity analysis: AU$ 16-112), which meant that every AU$1 invested in maintaining BFHI accreditation by this maternal and newborn care facility generated approximately AU$55 of benefit. CONCLUSIONS Scaled up nationally, the BFHI could provide important benefits to the Australian health system and national economy. In this public hospital, the BFHI produced social value greater than the cost of investment, providing new evidence of its effectiveness and economic gains as a public health intervention. Our findings using a novel tool to calculate the social rate of return, indicate that the BHFI accreditation is an investment in the health and wellbeing of families, communities and the Australian economy, as well as in health equity.

Abstract
BACKGROUND Assessing the quality of clinical research is a key evidence-based practice skill. Clinicians, guideline producers, policy makers, service commissioners, and families need to have a sense of the validity, applicability, and certainty of research evidence when determining how it should inform their decision-making and practice. METHODS We consider the various methodological and study design factors that contribute to the validity and applicability of clinical research findings. We describe the "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) methodology and discuss how this approach is used to assess and report certainty of evidence and strength of recommendations. RESULTS The randomized controlled trial (RCT) is the gold standard method for assessing interventions because randomization balances prognostic characteristics between comparison groups. The GRADE approach considers evidence from RCTs as high quality, but acknowledges that the quality and level of certainty of trial evidence may be "downgraded" based on consideration of threats across 5 domains: risk of bias in included trials, inconsistency between trials in outcome estimates, indirectness of the evidence, imprecision of estimates, and likelihood of publication bias. CONCLUSIONS Structured critical appraisal using GRADE methods to assess risk of bias and other threats to the internal and external validity of RCTs and systematic reviews and meta-analyses of their data facilitates transparency and consistency in using evidence to inform policy and practice.

Abstract
In spite of a large number of randomized placebo-controlled clinical trials and observational cohort studies including >50,000 preterm infants from 29 countries that have demonstrated a decrease in the risk of necrotizing enterocolitis, death, and sepsis, routine prophylactic probiotic administration to preterm infants remains uncommon in much of the world. This manuscript reflects talks given at NEC Society Symposium in 2019 and is not intended to be a state-of-the-art review or systematic review, but a summary of the probiotic-specific aspects of the symposium with limited additions including a recent strain-specific network analysis and position statement from the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN). We address ten common questions related to the intestinal microbiome and probiotic administration to the preterm infant.

Abstract
In this commentary, we summarize the current evidence from randomized controlled trials on enteral lactoferrin supplementation in preterm neonates. Our recently completed systematic review includes 12 randomized controlled trials performed all over the world. Our meta-analysis suggests clinical benefit in decreasing late-onset sepsis, late-onset fungal sepsis, length of stay in the hospital and urinary tract infections. There were no adverse effects. There was no statistically significant decrease in necrotizing enterocolitis, mortality or neurodevelopmental impairment in lactoferrin supplemented preterm infants. There was significant statistical heterogeneity in the effects of lactoferrin on late-onset sepsis between larger and smaller studies, which may reflect either small study biases, differences in the effectiveness, dose or duration of supplemental lactoferrin products, or differences in underlying population risk, or any or all of these.

Abstract
Advances in our understanding of the contribution of the gut microbiota to human health and the correlation of dysbiosis with diseases, including chronic intestinal conditions such as inflammatory bowel disease (IBD), have driven mechanistic investigations of probiotics in intestinal homeostasis and potential clinical applications. Probiotics have been shown to promote intestinal health by maintaining and restoring epithelial function, ensuring mucosal immune homeostasis, and inhibiting pathogenic bacteria. Recent findings reveal an approach for defining previously unrecognized probiotic-derived soluble factors as potential mechanisms of probiotic action. This review focuses on the impact of probiotics and probiotic-derived functional factors, including probiotic products and metabolites by probiotics, on the cellular responses and signaling pathways involved in maintaining intestinal homeostasis. Although there is limited information regarding the translation of probiotic treatment outcomes from in vitro and animal studies to clinical applications, potential approaches for increasing the clinical efficacy of probiotics for IBD, such as those based on probiotic-derived factors, are highlighted in this review. In this era of precision medicine and targeted therapies, more basic, preclinical, and clinical evidence is needed to clarify the efficacy of probiotics in maintaining intestinal health and preventing and treating disease.

Abstract
Feeding from own mother's milk is not always an option for preterm infants, and choosing between alternative means of feeding should be made in light of their effect on infants' health. In this work, we aimed to present evidence regarding feeding pre-term infants with human milk, either own mother's or donor milk (DM), and the potential effects on growth and other health related outcomes. Exclusive breastfeeding (BF) remains the optimal option, whereas feeding with DM as a sole diet or supplemental to maternal milk confers immunological advantages and fewer rates of necrotising enterocolitis against preterm formula feeding, yet the latter results in greater growth velocity. Literature gaps in the use of DM, practical suggestions for choosing suitable feeding means (i.e. continuous support of BF, adequate education regarding feeding preterm infants, including DM), and future perspectives on the potential effects of dietary manipulations of the maternal diet, are also discussed.
