RESUMO

OBJECTIVE: To describe the long-term health outcomes of neonates affected by necrotizing enterocolitis (NEC) and its implications for quality of life. DATA SOURCE: This is an integrative review, conducted by searching the literature in the following databases: Virtual Health Library (BVS), Latin American and Caribbean Health Sciences Literature (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), and PubMed, using Health Sciences Descriptors (DeCS): "necrotizing enterocolitis," "quality of life," and "prognosis" combined with the Boolean operators AND and OR: "quality of life" OR "prognosis." Inclusion criteria were: publication period between 2012 and 2022. DATA SYNTHESIS: A total of 1,010 studies were located, of which ten were selected to comprise the bibliographic sample of this review. Children with NEC are prone to exhibit cognitive neurological impairment, especially those who undergo surgical procedures due to more severe conditions. Motor development was considered below average when compared to healthy children, with more noticeable delays in fine and gross motor function development. The search for the relationship between NEC and quality of life revealed that this condition has a negative impact on the well-being of affected individuals. CONCLUSIONS: NEC has proven to be a serious condition contributing to high rates of morbidity and mortality in newborns, potentially leading to a reduction in the quality of life of affected patients.

RESUMO

OBJECTIVE: To assess the evaluation and prevalence of benign hematochezia (BH) vs necrotizing enterocolitis (NEC) in infants with congenital heart disease (CHD) <6 months old admitted to the acute care cardiology unit. STUDY DESIGN: This was a multicenter retrospective review of patient characteristics and evaluation of all hematochezia events in patients with CHD <6 months admitted to acute care cardiology unit at 3 high-volume tertiary care centers from February 2019 to January 2021. NEC was defined by the Bell staging criteria. Patients with gastrointestinal disorders were excluded. RESULTS: In total, 180 hematochezia events occurred in 121 patients; 42 patients had more than 1 event. In total, 61% of affected patients had single-ventricle physiology (38% hypoplastic left heart syndrome). Median age and weight at hematochezia were 38 days (IQR 24, 79) and 3.7 kg (IQR 3.2, 4.4). In total, 77% of hematochezia events were BH, and 23% were NEC. There were no surgical interventions for NEC or deaths from NEC. Those with NEC were significantly younger (34 vs 56 days, P < .01) and smaller (3.7 vs 4 kg, P < .01). Single-ventricle physiology was significantly associated with NEC. Initial bloodwork and diagnostic imaging at each center were assessed. There was no significant difference in white blood cell count or C-reactive protein in those with NEC compared with BH. Blood culture results were all negative. CONCLUSIONS: The majority of infants with CHD with hematochezia have BH over NEC, although single-ventricle and surgical patients remain at greater risk. Infants <45 days are more vulnerable for developing NEC. Bloodwork was noncontributory in the identification of cardiac NEC. Expansion to a prospective study to develop a treatment algorithm is important to avoid overtreatment.

RESUMO

Maternal, placental, and neonatal factors were compared between infants born at ≤29 weeks of gestational age with admission hyperthermia (>37.5○C) and euthermia (36.5-37.5○C). Admission hyperthermia was associated with longer duration of face-mask positive-pressure ventilation and infant's temperature ≥37.5○C in the delivery room. Infants born preterm with admission hyperthermia had greater odds of developing necrotizing enterocolitis and neurodevelopmental impairment.

RESUMO

BACKGROUND: Caffeine is commonly used as therapy for apnea of prematurity and has shown potential in preventing other conditions in preterm neonates. However, the optimal timing for caffeine therapy remains uncertain. OBJECTIVE: This study aimed to compare the outcomes of early versus late administration of caffeine in preterm neonates. METHODS: PubMed, Embase, and Cochrane Library were searched for studies comparing 0-2 days to ≥3 days caffeine introduction in preterm neonates. Outcomes included were mortality, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), patent ductus arteriosus (PDA), late-onset sepsis, length of hospital stay, and the composite of BPD or death. RevMan 5.4.1 was used for statistical analysis. RESULTS: A total of 122,579 patients from 11 studies were included, 2 were randomized controlled trials (RCTs), and 63.9% of the neonates received early caffeine administration. The rates of BPD (OR: 0.70; 95% CI: [0.60-0.81]; p < 0.0001), IVH (OR: 0.86; 95% CI: [0.82-0.90]; p < 0.0001), ROP (OR: 0.80; 95% CI: [0.74-0.86]; p < 0.0001), late-onset sepsis (OR: 0.84; 95% CI: [0.79-0.89]; p < 0.00001), and PDA (OR: 0.60; 95% CI: [0.47-0.78]; p < 0.0001) were significantly reduced in the early caffeine group. The composite outcome of BPD or death was also lower in the early caffeine group (OR: 0.76; 95% CI: [0.66-0.88]; p < 0.0003). Mortality rate was higher in the early caffeine group (OR: 1.20; 95% CI: 1.12-1.29; p < 0.001). CONCLUSION: As compared with late caffeine administration, early caffeine is associated with a reduction in BPD, IVH, ROP, late-onset sepsis, and PDA in preterm neonates, albeit increased mortality. Additional RCTs are warranted to confirm these findings and evaluate whether the effect on mortality may be related to survival bias in observational studies favoring the late treatment group.

RESUMO

OBJECTIVE: To develop an artificial intelligence-based software system for predicting late-onset sepsis (LOS) and necrotizing enterocolitis (NEC) in infants admitted to the neonatal intensive care unit (NICU). STUDY DESIGN: Single-center, retrospective cohort study, conducted in the NICU of the Antwerp University Hospital. Continuous monitoring data of 865 preterm infants born at <32 weeks gestational age, admitted to the NICU in the first week of life, were used to train an XGBoost machine learning (ML) algorithm for LOS and NEC prediction in a cross-validated setup. Afterward, the model's performance was assessed on an independent test set of 148 patients (internal validation). RESULTS: The ML model delivered hourly risk predictions with an overall sensitivity of 69% (142/206) for all LOS/NEC episodes and 81% (67/83) for severe LOS/NEC episodes. The model showed a median time gain of ≤10 hours (IQR, 3.1-21.0 hours), compared with historical clinical diagnosis. On the complete retrospective dataset, the ML model made 721 069 predictions, of which 9805 (1.3%) depicted a LOS/NEC probability of ≥0.15, resulting in a total alarm rate of <1 patient alarm-day per week. The model reached a similar performance on the internal validation set. CONCLUSIONS: Artificial intelligence technology can assist clinicians in the early detection of LOS and NEC in the NICU, which potentially can result in clinical and socioeconomic benefits. Additional studies are required to quantify further the effect of combining artificial and human intelligence on patient outcomes in the NICU.

RESUMO

BACKGROUND: Necrotizing enterocolitis (NEC) is the most common surgical disease in the neonatal period with a high mortality rate. To date, there is no consensus on the indications for surgery in the absence of pneumoperitoneum. This study aimed to determine the indications for surgery in pre-term infants with NEC and their mortality. METHODS: We conducted a descriptive, observational, cross-sectional, and retrospective study including pre-term infants with NEC from two perinatal hospitals in Toluca, Mexico, between 2017 and 2022. Descriptive and inferential statistics and group comparisons were performed using Fisher and Kruskal-Wallis tests. RESULTS: Of 236 patients with NEC, 52 (22%) required surgery; we analyzed 42 cases with complete clinical records. The indications for surgery were divided into (a) clinical deterioration (33.3%); (b) radiographic findings (31%); (c) laboratory alterations (19%); and (d) positive paracentesis (16.7%). The group of radiographic findings underwent surgery later, up to 2 days after the other groups. The mortality rate of surgical NEC was 42.9%. CONCLUSIONS: The most common indication for surgery in pre-term infants with NEC was clinical worsening despite optimal medical management; radiographic findings were the indication associated with the highest mortality. Laboratory abnormalities and positive paracentesis were the indications with the best outcomes but the least used.

INTRODUCCIÓN: La enterocolitis necrosante (ECN) es la enfermedad quirúrgica más frecuente en la etapa neonatal con una alta mortalidad. A la fecha, no existe consenso en las indicaciones quirúrgicas en ausencia de neumoperitoneo. El objetivo del estudio fue conocer las indicaciones de cirugía en neonatos pretérmino con ECN y la mortalidad. MÉTODOS: Se llevó a cabo un estudio descriptivo, observacional, transversal y retrospectivo, incluyendo a neonatos pretérmino con ECN de dos hospitales perinatales de Toluca, México, entre 2017 a 2022. Se realizó estadística descriptiva e inferencial y comparación de grupos con prueba de Fisher y Kruskal - Wallis. RESULTADOS: De 236 pacientes con ECN, 52 (22%) requirieron cirugía; se presenta el análisis de 42 casos con su expediente clínico completo. Las indicaciones para intervención se dividieron en los siguientes grupos: a) deterioro clínico (33.3%); b) hallazgos radiográficos (31%); c) alteraciones de laboratorio (19%) y d) paracentesis positiva (16.7%). El grupo de hallazgos radiográficos se operó más tardíamente, hasta dos días después de los demás grupos. La mortalidad en ECN quirúrgica fue del 42.9%. CONCLUSIONES: La indicación más utilizada para determinar cirugía en neonatos pretérmino con ECN fue el deterioro clínico a pesar de terapéutica médica máxima; los hallazgos radiográficos fueron la indicación que se relacionó con mayor mortalidad. Las alteraciones de laboratorio y paracentesis positiva fueron las de mejores resultados, pero las menos empleadas.

Introduction: Necrotizing Enterocolitis is a disease that can affect the gastrointestinal tract of newborns, whose clinical manifestations can be characterized by bilious vomiting, blood in stool, abdominal distension, in addition to changes in hemodynamic parameters and thermal instability. The populations most vulnerable to this disease are low birth weight newborns exposed to the neonatal intensive care environment. Objectives: This study aimed to identify the profile of newborns and maternal and neonatal factors associated with the occurrence of deaths from necrotizing enterocolitis in a reference maternity hospital in Ceará, Brazil. Methodology: This is a retrospective cohort study seeking to describe the incidence ofa particular event over time, as well as establish causal relationships between the factors associated with the event. The study population comprised newborns who died from necrotizing enterocolitis between 2019 and 2021, who had neonatal death investigation forms filled out correctly, with no newborns being excluded, totaling a sample of 29 deaths. Results: It was identified that the profile of newborns was mostly premature, of low birth weight and with risk factors for other associated diseases such as sepsis, leading to invasive procedures and hospitalization in a neonatal intensive care environment. Conclusions: Prematurity and low birth weight were relevant variables in the study and may be associated with worsening of the newborn's clinical conditionsand development of necrotizing enterocolitis (AU).

RESUMO

Introduction: The gastrointestinal and immune systems of premature infants are not fully developed, rendering them more vulnerable to severe complications like necrotizing enterocolitis. Human milk offers a rich array of bioactive factors that collectively contribute to reducing the incidence of gut infections and inflammatory conditions. When a mother's milk is unavailable, preterm infants are often provided with donor human milk processed in Human Milk Banks. However, it remains uncertain whether pasteurized milk confers the same level of risk reduction as unprocessed milk. This uncertainty may stem from the well-documented adverse effects of heat treatment on milk composition. Yet, our understanding of the comprehensive impact on protective mechanisms is limited. Methods: In this study, we conducted a comparative analysis of the effects of raw versus pasteurized milk and colostrum versus mature milk on cellular functions associated with the gut epithelial barrier and responses to inflammatory stimuli. We utilized THP-1 and HT-29 cell lines, representing monocyte/macrophages and gut epithelial cells, respectively. Results: Our observations revealed that all milk types stimulated epithelial cell proliferation. However, only raw colostrum increased cell migration and interfered with the interaction between E. coli and epithelial cells. Furthermore, the response of epithelial and macrophage cells to lipopolysaccharide (LPS) was enhanced solely by raw colostrum, with a milder effect observed with mature milk. In contrast, both raw and pasteurized milk diminished the LPS induced response in monocytes. Lastly, we examined how milk affected the differentiation of monocytes into macrophages, finding that milk reduced the subsequent inflammatory response of macrophages to LPS. Discussion: Our study sheds light on the impact of human milk on certain mechanisms that potentially account for its protective effects against necrotizing enterocolitis, highlighting the detrimental influence of pasteurization on some of these mechanisms. Our findings emphasize the urgency of developing alternative pasteurization methods to better preserve milk properties. Moreover, identifying the key components critically affected by these protective mechanisms could enable their inclusion in donor milk or formula, thereby enhancing immunological benefits for vulnerable newborns.
