Necrotising enterocolitis

Necrotising enterocolitis (NEC) has a complex pathophysiology but the common end-point is ischaemia reperfusion injury (IRI) and intestinal necrosis. We have previously reported that RIC significantly reduces the intestinal injury in a rat model of NEC. Here we describe the changes in intestinal mRNA occurring in the intestine of animals exposed to IRI, both with and without RIC. Related rat-pups were randomly assigned to four groups: SHAM, IRI only, RIC only and RIC + IRI. IRI animals, underwent 40 min of intestinal ischaemia, and 90 min of reperfusion...

BACKGROUND: Preterm infants (born before 37 weeks' gestation) are often unable to co-ordinate sucking, swallowing, and breathing for oral feeding because of their immaturity. In such cases, initial nutrition is provided by orogastric or nasogastric tube feeding. Feeding intolerance is common and can delay attainment of full enteral and sucking feeds, prolonging the need for nutritional support and the hospital stay. Smell and taste play an important role in the activation of physiological pre-absorptive processes that contribute to food digestion and absorption...

OBJECTIVE: This study aimed to evaluate the role of receptor-interacting protein kinase-3 (RIPK3) in the diagnosis, estimation of disease severity, and prognosis of premature infants with necrotising enterocolitis (NEC). METHODS: RIPK3, lactic acid (LA), and C-reactive protein (CRP) levels were measured in the peripheral blood of 108 premature infants between 2019 and 2023, including 24 with stage II NEC, 18 with stage III NEC and 66 controls. Diagnostic values of the indicators for NEC were evaluated via receiver operating characteristic (ROC) curve analysis...

UNLABELLED: While neonatal necrotising enterocolitis (NEC) is associated with high mortality rates in newborns, survivors can face long-term sequelae. However, the relationship between NEC and neurodevelopmental impairment (NDI) in preterm infants remains unclear. To explore the relationship between neonatal NEC and neurodevelopmental outcomes in preterm infants, we searched PubMed, EMBASE, and the Cochrane Library from their inception to February 2024 for relevant studies. Studies included were cohort or case-control studies reporting neurodevelopmental outcomes of NEC in preterm infants...

AIM: There is limited literature available about necrotising enterocolitis (NEC) in low- and middle-income countries. This study sought to determine the proportion, pattern and risk factors for mortality among very low birth weight (VLBW) neonates with NEC in a middle-income setting. METHODS: A retrospective observational cohort study was conducted on all infants with birth weights less than 1501 g admitted from 2018 to 2020 at Groote Schuur Hospital, Cape Town, South Africa...

INTRODUCTION: Various approaches are employed to expedite the passage of meconium in preterm infants within the neonatal intensive care unit (NICU), with glycerine enemas being the most frequently used. Due to the potential risk of high osmolality-induced harm to the intestinal mucosa, diluted glycerine enema solutions are commonly used in clinical practice. The challenge lies in the current lack of knowledge regarding the safest and most effective concentration of glycerine enema. This research aims to ascertain the safety of different concentrations of glycerine enema solution in preterm infants...

PURPOSE: Obtaining large volumes of medical images, required for deep learning development, can be challenging in rare pathologies. Image augmentation and preprocessing offer viable solutions. This work explores the case of necrotising enterocolitis (NEC), a rare but life-threatening condition affecting premature neonates, with challenging radiological diagnosis. We investigate data augmentation and preprocessing techniques and propose two optimised pipelines for developing reliable computer-aided diagnosis models on a limited NEC dataset...

OBJECTIVE: Caffeine is widely used in preterm infants to prevent or treat apnoea of prematurity. Adverse gastrointestinal effects of caffeine have not been thoroughly researched in preterm infants. With this systematic review and meta-analysis, we aim to summarise the results of trials on the gastrointestinal effects of caffeine in preterm infants. DESIGN: We searched MEDLINE, Web of Science, Scopus and ClinicalTrials.gov up to 21 April 2023. We included randomised controlled trials assessing caffeine versus placebo in preterm neonates and reporting gastrointestinal side effects...

Breastfeeding is a crucial public health approach that reduces infant morbidity and mortality by providing essential nutrients and antibodies, and breast milk is easily digested. Breastfeeding and donated milk serve as a preventative measure against necrotising enterocolitis. Additionally, they protect against viruses and nosocomial sepsis. When a birthing parent's own milk is unavailable, alternative enteral nutrition for preterm or low-birth-weight infants is either donor human milk (DHM) or artificial formula...

BACKGROUND: Mortality and severe morbidity remain high in extremely preterm infants. Human milk-based nutrient fortifiers may prevent serious complications and death. We aimed to investigate whether supplementation with human milk-based fortifier (HMBF), as compared to bovine milk-based fortifier (BMBF), reduced the incidence of the composite outcome of necrotising enterocolitis (NEC), sepsis, and mortality in extremely preterm infants exclusively fed human milk. METHODS: In this multicentre, randomised controlled trial at 24 neonatal units in Sweden, extremely preterm infants born between gestational week 22 + 0 and 27 + 6 fed exclusively human breast milk (mother's own and/or donor milk), were randomly assigned (1:1) to receive targeted fortification with either HMBF or BMBF...

Inflammation, oxidative injury, and gut dysbiosis play an important role in the pathogenesis of necrotising enterocolitis (NEC). Plant-derived substances have historically been used as therapeutic agents due to their anti-inflammatory, antioxidant, and antimicrobial properties. We aimed to review pre-clinical evidence for plant-derived substances in the prevention and treatment of NEC. A systematic review was conducted using the following databases: PubMed, EMBASE, EMCARE, MEDLINE and Cochrane Library (PROSPERO CRD42022365477)...

OBJECTIVE: The aim of our study was to describe postnatal blood pressure (BP) trends and evaluate relevant dynamics and outcomes for a subgroup of extremely preterm (EPT) infants. DESIGN: Retrospective observational cohort study. SETTING: Patients admitted to Karolinska University Hospital Stockholm. PATIENTS: EPT infants born between 22+0 and 24+6 weeks' gestational age (GA) undergoing invasive, continuous BP monitoring through an umbilical arterial catheter...

BACKGROUND: Preterm (born < 37 weeks' gestation) and very low birthweight (VLBW; <1.5kg) infants are at the greatest risk of morbidity and mortality within the first 28 days of life. Establishing full enteral feeds is a vital aspect of their clinical care. Evidence predominantly from high income countries shows that early and rapid advancement of feeds is safe and reduces length of hospital stay and adverse health outcomes. However, there are limited data on feeding practices and factors that influence the attainment of full enteral feeds among these vulnerable infants in sub-Saharan Africa...

Surgically treated necrotising enterocolitis (sNEC) is associated with significantly worse neurodevelopmental outcomes than that seen in premature infants without NEC. We aim to review the association between factors involved in the surgical treatment of NEC and subsequent neurodevelopmental outcomes to identify potential areas for improvement. The PubMed and Embase databases were interrogated for articles reporting neurodevelopmental outcomes in babies treated surgically for NEC using key terms including: "Infant", "Necrotising enterocolitis", "Surgical", "Neurodevelopmental" and "Outcomes"...

BACKGROUND: The nutritional practice for newborns with hypoxic-ischaemic encephalopathy during therapeutic hypothermia differs among Polish neonatal care units, as no guidelines are provided. We assessed the prevailing procedures. MATERIAL AND METHODS: Data was collected through an anonymous, web-based questionnaire. We surveyed aspects of the current nutritional practices and the reasoning behind the choice of the feeding strategy. RESULTS: Thirty-one responses were obtained (31/33, 94%)...

PURPOSE: Gastric residual measurement is routinely performed in premature infants prior to feeding despite a lack of evidence of benefit. We aimed to evaluate if the exclusion of routine gastric residual measurement and evaluation has an impact on the time taken to achieve full enteral feeding in preterm neonates. METHODS: International multi-centre randomised controlled trial. Clinically stable, appropriate for gestational age infants between 26+0 and 30+6  weeks of gestation and less than 1...

BACKGROUND: While ursodeoxycholic acid is used in treating parenteral nutrition-associated cholestasis (PNAC) in neonates, its role in prevention is unclear. OBJECTIVES: In this systematic review and meta-analysis, we attempted to determine the role of ursodeoxycholic acid in preventing PNAC in neonates. METHODS: PubMed, Embase, Cochrane Library, Scopus, and CINAHL databases were searched on September 16, 2023, for interventional studies comparing ursodeoxycholic acid with placebo...

Necrotising enterocolitis (NEC) is a devastating condition that poses a significant risk of morbidity and mortality, particularly among preterm babies. Extensive research efforts have been directed at identifying optimal treatment and diagnostic strategies but results from such studies remain unclear and controversial. Among the most promising candidates are prebiotics, probiotics and their metabolites, including short chain fatty acids (SCFAs). Such metabolites have been widely explored as possible biomarkers of gut health for different clinical conditions, with overall positive effects on the host observed...
