Recent research on machine learning in the diagnosis and treatment of necrotizing enterocolitis in neonates / 中国当代儿科杂志

Necrotizing enterocolitis (NEC), with the main manifestations of bloody stool, abdominal distension, and vomiting, is one of the leading causes of death in neonates, and early identification and diagnosis are crucial for the prognosis of NEC. The emergence and development of machine learning has provided the potential for early, rapid, and accurate identification of this disease. This article summarizes the algorithms of machine learning recently used in NEC, analyzes the high-risk predictive factors revealed by these algorithms, evaluates the ability and characteristics of machine learning in the etiology, definition, and diagnosis of NEC, and discusses the challenges and prospects for the future application of machine learning in NEC.

The evolution of approach in the resuscitation of neonates born with meconium-stained amniotic fluid: a tale of two countries, China and U.S.A., in the past 60 years / 中国当代儿科杂志

Neonates born through meconium-stained amniotic fluid (MSAF) may develop complications including meconium aspiration syndrome, persistent pulmonary hypertension of newborn and death. The approach to the resuscitation of these neonates has significantly evolved for the past few decades. Initially, under direct visualization technique, neonates with MSAF were commonly suctioned below the vocal cords soon after delivery. Since 2015, Neonatal Resuscitation Program (NRP®) of the American Academy of Pediatrics has recommended against "routine" endotracheal suctioning of non-vigorous neonates with MSAF but favored immediate resuscitation with positive pressure ventilation via face-mask bagging. However, the China neonatal resuscitation 2021 guidelines continue to recommend routine endotracheal suctioning of non-vigorous neonates born with MSAF at birth. This review article discusses the differences and the rationales in the approach in the resuscitation of neonates with MSAF between Chinese and American NRP® guidelines over the past 60 years.

Clinical characteristics and risk factors for early-onset necrotizing enterocolitis in preterm infants with very/extremely low birth weight / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical characteristics and risk factors for early-onset necrotizing enterocolitis (NEC) in preterm infants with very/extremely low birth weight (VLBW/ELBW).@*METHODS@#A retrospective analysis was performed on the medical data of 194 VLBW/ELBW preterm infants with NEC who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2014 to December 2021. These infants were divided into early-onset group (onset in the first two weeks of life; n=62) and late-onset group (onset two weeks after birth; n=132) based on their onset time. The two groups were compared in terms of perinatal conditions, clinical characteristics, laboratory examination results, and clinical outcomes. Sixty-two non-NEC infants with similar gestational age and birth weight who were hospitalized at the same period as these NEC preterm infants were selected as the control group. The risk factors for the development of early-onset NEC were identified using multivariate logistic regression analysis.@*RESULTS@#Compared with the late-onset group, the early-onset group had significantly higher proportions of infants with 1-minute Apgar score ≤3, stage III NEC, surgical intervention, grade ≥3 intraventricular hemorrhage, apnea, and fever or hypothermia (P<0.05). The multivariate logistic regression analysis showed that feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, and hemodynamically significant patent ductus arteriosus were independent risk factors for the development of early-onset NEC in VLBW/ELBW preterm infants (P<0.05).@*CONCLUSIONS@#VLBW/ELBW preterm infants with early-onset NEC have more severe conditions compared with those with late-onset NEC. Neonates with feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, or hemodynamically significant patent ductus arteriosus have a higher risk of early-onset NEC.

To describe the fetal adverse effects AED exposure during gestation, reported in the literature during the period 2016-2022. Systematized review of studies that reported fetal adverse effects induced for the exposure to AED in pregnant women in treatment for neurological diagnoses, mainly epilepsy. The search was carried out in PubMed, Cochrane, Web of Science, SCOPUS, Virtual Health Library, Lilacs and SciELO. 37 articles distributed in thirteen countries in Asia, Europe, North America and Oceania were identified. Adverse perinatal outcomes, both physical and cognitive, were observed in most studies. The most common drugs identified were valproate, topiramate, carbamazepine, lamotrigine and levetiracetam. AED have teratogenic potential in different degrees of risk, causing congenital anomalies or adverse effects in multiple systems of the human body, being the nervous, circulatory and musculoskeletal systems the most affected.

Association of maternal clinical factors with neonatal respiratory morbidity in meconium‑stained labor among term parturients: A retrospective cohort study / Philippine Journal of Obstetrics and Gynecology

Objective@#This study aimed to determine the maternal clinical factors associated with neonatal respiratory morbidity and other adverse neonatal outcomes in meconium-stained labor among term parturients.@*Methodology@#A retrospective cohort study was done on admitted obstetric patients with term gestation and had meconium-stained labor. Maternal clinical factors such as age, parity, gestational age, manner of delivery, duration of labor, presence of term prelabor rupture of membranes (PROM), character of meconium-stained liquor (MSL), and presence of comorbidities were identified and analyzed to determine their association with neonatal respiratory morbidity and other adverse neonatal outcomes. @*Results@#In this study, there were 986 cases identified to have meconium-stained labor, and 168 developed neonatal respiratory morbidity. As to primary outcome, maternal clinical factors, such as age >35 years, multiparity, age of gestation >41 weeks, prolonged labor, presence of PROM, significant MSL upon admission, presence of change from nonsignificant to significant MSL, presence of intrauterine growth restriction, and hypertension, were all shown to be statistically significant. @*Conclusion@#The presence of maternal clinical factors in meconium-stained labor was observed to be a risk factor in developing neonatal respiratory morbidity and other adverse neonatal outcomes. Hence, identification of maternal risk factors and early detection of meconium-stained amniotic fluid are vital in administering timely intervention to labor and delivery to reduce neonatal complications.

Hipoglucemia neonatal en hijos de madres con diabetes mellitus gestacional. Comparación de la incidencia según el tratamiento materno / Neonatal hypoglycemia in infants born to mothers with gestational diabetes mellitus. Comparison of its incidence based on maternal treatment

Introducción. La hipoglucemia neonatal es una complicación de la diabetes mellitus gestacional Son pocos los estudios que avalan la pesquisa sistemática en este grupo poblacional durante las primeras horas de vida. Objetivos. Evaluar la asociación entre tratamiento materno recibido (dieta versus insulina) y el desarrollo de hipoglucemia, e identificar los factores de riesgo asociados. Población y métodos. Estudio observacional, analítico y retrospectivo realizado en en las sedes de Buenos AIres y San Justo de un hospital general de tercer nivel entre el 1 de enero de 2017 y el 31 de diciembre de 2018. Se estimó la incidencia de hipoglucemia (≤47 mg/dl) en recién nacidos según el manejo de la diabetes materna y se realizó un análisis multivariable para evaluar factores asociados. Resultados. Se incluyeron 195 pacientes. No se encontró diferencia estadística en la incidencia de hipoglucemia según el tratamiento materno recibido (45,3 % versus 39,7 %; p = 0,45) ni se identificaron factores de riesgo asociados. Modificando el valor de corte a ≤40 mg/dl, tampoco se encontraron diferencias en la incidencia (23,4 % versus 19 %, p = 0,48); no obstante, los pacientes hipoglucémicos presentaron un hematocrito significativamente mayor y una menor prevalencia de lactancia exclusiva al egreso. El análisis multivariable mostró una asociación independiente entre alto peso al nacer con hipoglucemia que requiere corrección. Conclusiones. La incidencia de hipoglucemia neonatal en la población estudiada no presentó diferencia según el tratamiento materno recibido. El estudio realizado fundamenta el control de la glucemia en estos niños en la práctica diaria.

Introduction. Neonatal hypoglycemia is a complication of gestational diabetes mellitus. Few studies have been conducted to support a systematic screening in the first hours of life of this population group. Objectives. To assess the association between the treatment administered to the mother (diet vs. insulin) and the development of hypoglycemia, and to identify associated risk factors. Population and methods. Observational, analytical, and retrospective study carried out at the Buenos Aires and San Justo maternal centers of a general, tertiary care hospital between 01-01-2017 and 12-31-2018. The incidence of neonatal hypoglycemia (≤ 47 mg/dL) based on the management of maternal diabetes was estimated and a multivariate analysis was done to assess related factors. Results. A total of 195 patients were included. No statistical difference was found in the incidence of hypoglycemia based on the treatment administered to the mother (45.3% vs. 39.7%; p = 0.45) and no associated risk factors were identified. Once the cutoff point was changed to ≤ 40 mg/dL, no differences were found in the incidence either (23.4% versus 19%, p = 0.48); however, patients with hypoglycemia had a significantly higher hematocrit level and a lower prevalence of exclusive breastfeeding upon discharge. Multivariate analysis showed an independent association between a high birth weight and hypoglycemia, requiring correction. Conclusions. The incidence of neonatal hypoglycemia in the studied population did not vary based on the treatment received by the mother. This study supports the control of glycemia in these infants in daily practice.

Enterocolitis necrosante posterior a evento aislado de taquicardia supraventricular: reporte de un caso de presentación neonatal atípica / Necrotizing enterocolitis after an isolated event of supraventricular tachycardia. Case report of atypical neonatal presentation

La taquicardia supraventricular (TSV) es la principal taquiarritmia en el recién nacido (RN) que requiere una resolución urgente. Por su parte, la enterocolitis necrosante (ECN) es la emergencia gastrointestinal más común que afecta principalmente a RN prematuros. Aunque estas se reconocen como patologías distintas, la bibliografía sugiere que los episodios de TSV pueden predisponer a los pacientes a la ECN a través de alteraciones en el flujo sanguíneo mesentérico y una disminución de la perfusión tisular. Se presenta aquí el caso clínico de un neonato prematuro que desarrolló un cuadro de ECN luego de un evento aislado de TSV con bajo gasto cardíaco

Supraventricular tachycardia (SVT) is the main tachyarrhythmia in the newborn (NB) that requires urgent resolution. Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency that mainly affects premature infants. Although these conditions are recognized as distinct pathologies, literature reports suggest that episodes of SVT may predispose patients to NEC secondary to disturbances in mesenteric blood flow and a decrease in tissue perfusion. We present here the clinical case of a premature neonate who developed NEC after an isolated SVT event with low cardiac output

Objetivo: identificar na literatura as implicações relacionadas à transfusão de hemácias, por meio do Cateter Central de Inserção Periférica, em neonatos. Métodos: revisão integrativa realizada nas bases de dados Web of Science, Scopus, Biblioteca Virtual em Saúde e PUBMED. Incluíram-se publicações em inglês, espanhol e português, disponíveis na íntegra, sem data limite. Resultados: selecionaram-se quatro (100,0%) pesquisas que abordaram hemólise das hemácias e dois deles (50,0%), também, versaram sobre obstrução do cateter durante a transfusão. Os estudos evidenciaram ocorrência de hemólise relacionada à velocidade de infusão e ao tempo de armazenamento das hemácias, porém sem relevância clínica. Referente à obstrução, observou-se ocorrência em apenas um cateter de 38 acompanhados em um estudo; no outro, não houve obstrução, sendo as transfusões consideradas tecnicamente viáveis. Conclusão: urgem estudos clínicos primários que avaliem as consequências clínicas das transfusões de hemácias por esse tipo de cateter, em neonatos.

Objective: this study aimed to identify in literature the implications related to red blood cell (RBC) transfusions, through Peripherally Inserted Central Catheter, in neonates. Methods: this is an integrative review conducted in the Web of Science, Scopus, Virtual Health Library, and PubMed databases. Publications in English, Spanish and Portuguese, available in full, without date limit, were included. Results: four (100.0%) studies that addressed hemolysis of RBCs were selected, of which two (50.0%) also addressed catheter obstruction during transfusion. Studies revealed the occurrence of hemolysis related to infusion rate and storage time of RBCs, however without clinical relevance. Regarding obstruction, it was verified in only one catheter out of 38 followed-up in a study; in the other, there was no obstruction and transfusions were considered technically feasible. Conclusion:there is urgent need for primary clinical studies to assess clinical consequences of red blood cell transfusions through this type of catheter in neonates.

Estado nutricional de la mujer embarazada y su relación con las complicaciones de la gestación y el recién nacido / Nutrition status of pregnant women and its relationship with complications of pregnancy and the newborn

RESUMEN: El estado nutricional materno determina las condiciones de salud y nutricionales del recién nacido, así como las complicaciones durante el embarazo y el parto. Se realizó el estudio en 894 mujeres que tuvieron su parto en los Hospitales de la ciudad de Loja Ecuador durante el periodo enero - junio del 2019. Se determinó la antropometría de la madre y de su hijo, así como se tomó datos de complicaciones durante el embarazo y el parto, de su historia clínica. Además, se efectuó la correlación entre el estado nutricional pre-gestacional de la madre con el recién nacido, de igual forma con el estado de salud de la madre. El objetivo de este trabajo fue determinar el estado nutricional pre-gestacional y su relación con la condición de salud y nutricional del niño. El IMC pre-gestacional reportó 47,3 % de sobrepeso y obesidad y 2,6 % de bajo peso. En un porcentaje mayor al 10 % las madres con sobrepeso y obesidad tuvieron hijos grandes para la edad gestacional, de igual forma las madres con bajo peso tuvieron el 26,1 % recién nacidos pequeños. Las principales complicaciones de las madres relacionadas con sobrepeso y obesidad fueron: diabetes gestacional, hemorragia postparto y pre-eclampsia durante el embrazo. Importante señalar la alta frecuencia de infecciones de las vías urinarias 53,9 % (478); y vaginitis 22,3 % (199); aunque estas no están directamente relacionadas con procesos metabólicos como etiología, más si están favorecidos por ellos. Durante el parto la complicación más frecuente fue el parto distócico con un 8,9 % (77), además del total de partos el 41,8 % (374) terminaron en cesárea, de estos el 51, 6 % (193) corresponden a sobrepeso y obesidad. Las complicaciones del recién nacido fueron: Síndrome de dificultad respiratoria aguda, asfixia neonatal e hipoglicemia. En conclusión, el estado nutricional pre-gestacional de la madre está relacionado directamente con el estado de salud y nutricional del recién nacido.

SUMMARY: The maternal nutritional status determines the health and nutritional conditions of the newborn, as well as complications during pregnancy and childbirth. The study was carried out in 894 women who had their delivery in the Hospitals of the city of Loja Ecuador during the period January - June 2019. The anthropometry of the mother and her child was determined, as well as data on complications during pregnancy and delivery, from their clinical history. In addition, the correlation was made between the pre-gestational nutritional status of the mother with the newborn, in the same way with the health status of the mother. The objective of this work was to determine the pre-gestational nutritional status and its relationship with the health and nutritional condition of the child. The pre-gestational BMI reported 47.3 % overweight and obesity and 2.6 % underweight. In a percentage higher than 10 %, mothers with overweight and obesity had large children for gestational age, in the same way, mothers with low weight had 26.1 % small newborns. The main complications of the mothers related to overweight and obesity were: gestational diabe- tes, postpartum hemorrhage and pre-eclampsia during pregnancy. It is important to note the high frequency of urinary tract infections 53.9% (478); and vaginitis 22.3% (199; although these are not directly related to metabolic processes such as etiology, more if they are favored by them. During delivery, the most frequent complication was dystocic delivery with 8.9 % (77), in addition to the total deliveries 42.5 % (374) that ended in cesarean section, of which 51.6 % (193) correspond to overweight and obesity. The complications of the newborn were: Acute respiratory distress syndrome, neonatal asphyxia and hypoglycemia. In conclusion, the pre-gestational nutritional status of the mother is directly related to the health and nutritional status of the newborn.

Particularités de l'infection néonatale bactérienne précoce en milieu hospitalier du CHU Gabriel Touré de Bamako / Particularities of early neonatal bacterial infection in the hospital environment of the CHU Gabriel Touré in Bamako

Introduction : L'infection néonatale bactérienne précoce (INBP) est une préoccupation majeure en néonatologie. Au Mali, aucune étude n'avait abordé cet aspect d'où l'initiation du présent travail afin d'étudier le profil épidémio-clinique, biologique et bactériologique de l'INBP. Matériel et méthodes :Il s'est agi d'une étude longitudinale descriptive qui s'est déroulée du 27 juin au 03 septembre 2016 ayant concerné les nouveau-nés d'âge ≤ à 72 heures hospitalisés pour INBP confirmée à l'hémoculture dans le service de néonatologie du département de pédiatrie du Centre Hospitalier et Universitaire (CHU) Gabriel Touré de Bamako. Les paramètres étudiés étaient les caractéristiques sociodémographiques et obstétricales des mères, les caractéristiques cliniques, biologiques et bactériologiques des nouveau-nés infectés précocement. Résultats : Sur les 324 hémocultures réalisées, 52 étaient positives soit une fréquence d'INBP de 11,04 %. Le sex-ratio était de 1,3 avec 73,1% de petit poids de naissance. A l'admission, 90,4 % des nouveau-nés avait moins de 24 H de vie et 86, 5%étaient des naissances hors du CHU Gabriel Touré. Les principaux signes cliniques étaient l'hyperthermie ou l'hypothermie et la détresse respiratoire. Les principales bactéries isolées à l'hémoculture étaient Staphylococcus aureus (55,8%), Klebsiella pneumoniae (13,5 %) et Escherichia coli (07,7 %). La sensibilité à la biantibiothérapie de première intention (ceftriaxone + gentamicine)était faible (63,6%) et celle de l'amikacine était meilleure (100 %). La moitié des nouveau-nés infectés précocement est décédée et 19,2% d'exéat sans accord médical a été enregistrée. Conclusion: L'infection néonatale bactérienne précoce est une cause majeure de morbi-mortalité néonatale. Dans notre contexte, l'amikacine pourrait être une meilleure alternative thérapeutique

Introduction: Early neonatal bacterial infection (ENBI) is a major concern in neonatology. In Mali, no study had addressed this aspect, hence the initiation of this work to study the epidemiological-clinical, biological and bacteriological profile of ENBI. Materials and methods: This were a descriptive longitudinal study that took place from june 27 to september 3, 2016 involving newborns aged ≤ 72 hours hospitalized for ENBI confirmed by blood culture in the neonatology service of the pediatrics department of the Center Hospitalier et Universitaire (CHU) Gabriel Toure in Bamako. The parameters studied were the socio-demographic and obstetrical characteristics of the mothers, the clinical, biological and bacteriological characteristics of newborns infected early. Results: Of the 324 blood cultures performed, 52 were positive, i.e. an ENBI frequency of 11.04%. The sex ratio was 1.3 with 73.1% low birth weight. On admission, 90.4% of newborns had less than 24 hours of life and 86.5% were births outside the CHU Gabriel Toure. The main clinical signs were hyperthermia or hypothermia and respiratory distress. The main bacteria isolated in blood culture were Staphylococcus aureus (55.8%), Klebsiella pneumoniae (13.5%) and Escherichia coli (07.7%). Sensitivity to first-line biantibiotic therapy (ceftriaxone + gentamicin) was low (63.6%) and that of amikacin was better (100%). Half of the newborns infected early died and 19.2% of exeat without medical agreement was recorded. Conclusion: Early neonatal bacterial infection is a major cause of neonatal morbidity and mortality. In our context, amikacin could be a better therapeutic alternative

Recent research on gene polymorphisms related to caffeine therapy in preterm infants with apnea of prematurity / 中国当代儿科杂志

Apnea of prematurity (AOP) is one of the common diseases in preterm infants. The main cause of AOP is immature development of the respiratory control center. If AOP is not treated timely and effectively, it will lead to respiratory failure, hypoxic brain injury, and even death in severe cases. Caffeine is the first choice for the treatment of AOP, but its effectiveness varies in preterm infants. With the deepening of AOP research, more and more genetic factors have been confirmed to play important roles in the pathogenesis and treatment of AOP; in particular, the influence of single nucleotide polymorphism on the efficacy of caffeine has become a research hotspot in recent years. This article reviews the gene polymorphisms that affect the efficacy of caffeine, in order to provide a reference for individualized caffeine therapy. Citation.

Establishment of a nomogram model for predicting necrotizing enterocolitis in very preterm infants / 中国当代儿科杂志

OBJECTIVES@#To investigate the risk factors for necrotizing enterocolitis (NEC) in very preterm infants and establish a nomogram model for predicting the risk of NEC.@*METHODS@#A total of 752 very preterm infants who were hospitalized from January 2015 to December 2021 were enrolled as subjects, among whom 654 were born in 2015-2020 (development set) and 98 were born in 2021 (validation set). According to the presence or absence of NEC, the development set was divided into two groups: NEC (n=77) and non-NEC (n=577). A multivariate logistic regression analysis was used to investigate the independent risk factors for NEC in very preterm infants. R software was used to plot the nomogram model. The nomogram model was then validated by the data of the validation set. The receiver operating characteristic (ROC) curve, the Hosmer-Lemeshow goodness-of-fit test, and the calibration curve were used to evaluate the performance of the nomogram model, and the clinical decision curve was used to assess the clinical practicability of the model.@*RESULTS@#The multivariate logistic regression analysis showed that neonatal asphyxia, sepsis, shock, hypoalbuminemia, severe anemia, and formula feeding were independent risk factors for NEC in very preterm infants (P<0.05). The ROC curve of the development set had an area under the curve (AUC) of 0.833 (95%CI: 0.715-0.952), and the ROC curve of the validation set had an AUC of 0.826 (95%CI: 0.797-0.862), suggesting that the nomogram model had a good discriminatory ability. The calibration curve analysis and the Hosmer-Lemeshow goodness-of-fit test showed good accuracy and consistency between the predicted value of the model and the actual value.@*CONCLUSIONS@#Neonatal asphyxia, sepsis, shock, hypoalbuminemia, severe anemia, and formula feeding are independent risk factors for NEC in very preterm infant. The nomogram model based on the multivariate logistic regression analysis provides a quantitative, simple, and intuitive tool for early assessment of the development of NEC in very preterm infants in clinical practice.
