RESUMEN

INTRODUCTION: Currently, kangaroo mother care (KMC) is an intervention whose implementation in clinical practice varies widely. The aim of this document is to gather the latest evidence-based recommendations in an attempt to reduce interprofessional variation and increase the quality of neonatal care. METHODS: The document was developed following the guidelines provided in the Methodological Manual for the Development of Clinical Practice Guidelines of the National Health System: formulation and prioritization of clinical questions, literature search, critical reading, development of the document and external review. The target population was preterm (PT) and/or low birth weight (LBW) newborn infants admitted to a neonatal unit. RECOMMENDATIONS: Based on the current evidence, recommendations have been issued to address 18 clinical questions regarding the impact of KMC (morbidity and mortality, physiological stability, neurodevelopment, feeding, pain, families), including infants with vascular access or respiratory support devices. It also describes the KMC procedure (transfer, positioning), the facilitators and barriers related to the implementation of KMC and how to implement KMC in extremely preterm newborns (less than 28 weeks of postmenstrual age in the first days of life). CONCLUSIONS: Kangaroo mother care is a beneficial practice for PT infants, LBW infants and their families. The implementation of these recommendations may be useful in everyday clinical practice and may improve KMC outcomes and the quality of care provided to neonatal patients.

RESUMEN

Introducción. El levetiracetam (LEV) es un antiepiléptico aprobado por el Instituto de Salud Pública de Chile como terapia concomitante en crisis epilépticas en niños mayores de cuatro años. Sin embargo, es ampliamente indicado desde el periodo neonatal, lo que hace necesario evaluar su utilización fuera de ficha técnica. Objetivo. Determinar el perfil de prescripción-indicación de LEV en el tratamiento de las crisis epilépticas en menores de cuatro años en un hospital de alta complejidad del sur de Chile. Población y método. Estudio observacional, descriptivo y retrospectivo. Se revisaron las historias clínicas de quienes iniciaron tratamiento con LEV entre 2014 y 2019, y se recopilaron datos sobre variables sociodemográficas, farmacológicas y clínicas. El análisis se basó en la descripción del perfil de los pacientes, prescripción, seguimiento y seguridad. Resultados. Se incluyeron 68 pacientes: 40 (58,8 %) de sexo masculino, 49 (72,1 %) con edad gestacional ≥ 37 semanas. La etiología principal de la epilepsia fue de tipo estructural (35,3 %); el LEV se utilizó principalmente en niños diagnosticados con malformación del sistema nervioso central (17,6 %) y predominó la monoterapia (55,9 %). En el 50 % se usó LEV para crisis focales. Cinco niños (7,3 %) presentaron trastornos de tipo psiquiátrico clasificados como probables reacciones adversas al medicamento. Conclusión. El LEV se utilizó en niños con diferentes diagnósticos con baja frecuencia de eventos adversos. El perfil de utilización varió en los diferentes grupos etarios. Es necesario identificar en futuros estudios la efectividad especialmente en el recién nacido y en epilepsias refractarias.

Introduction. Levetiracetam (LEV) is an antiepileptic drug approved by the Chilean Institute of Public Health as concomitant therapy for epileptic seizures in children older than 4 years of age. However, it is widely prescribed from the neonatal period, which makes it necessary to evaluate its off-label use. Objective. To determine the prescription-indication profile of LEV in the treatment of epileptic seizures in children younger than 4 years in a tertiary care hospital in southern Chile. Population and method. Observational, descriptive, and retrospective study. The medical records of patients who started treatment with LEV between 2014 and 2019 were reviewed, and data on sociodemographic, pharmacological, and clinical variables were collected. The analysis was based on the description of the profile of patients, prescriptions, follow-up, and safety. Results. A total of 68 patients were included: 40 (58.8%) were males, 49 (72.1%) were born at a gestational age ≥ 37 weeks. The main etiology of epilepsy was structural (35.3%); LEV was mostly used in children diagnosed with central nervous system malformation (17.6%), and monotherapy was the prevailing dosage (55.9%). LEV was used for focal seizures in 50% of cases. Five children (7.3%) had psychiatric disorders, classified as probable adverse drug reactions. Conclusion. LEV was used in children with various diagnoses, with a low rate of adverse events. The profile of drug use varied in the different age groups. Future studies are needed to identify effectiveness, especially in newborn infants and patients with refractory epilepsy.

RESUMEN

Los problemas de salud mental materna durante el embarazo, parto y puerperio son un desafío para la salud pública. Su falta de reconocimiento atenta contra el diagnóstico y tratamientos oportunos, e impacta en la madre y el establecimiento del vínculo fundamental del binomio. Debemos reconocer los factores de riesgo (edad, situación socioeconómica, antecedentes psicopatológicos, disfunción familiar, entorno desfavorable), las manifestaciones clínicas y las herramientas de detección. Existen evidencias de que el efecto del estrés, la ansiedad y la depresión durante el embarazo afectan negativamente el neurodesarrollo fetal y condicionan los resultados del desarrollo infantil. Describimos el impacto negativo de la depresión puerperal durante los primeros meses de vida, que afecta el vínculo madre-hija/o, el desarrollo posnatal (emocional, conductual, cognitivo, lenguaje) y el mantenimiento de la lactancia materna. También reconocemos factores protectores que atemperan sus efectos. Es fundamental establecer estrategias preventivas y abordajes diagnósticos y terapéuticos interdisciplinarios para minimizar los riesgos sobre la madre y sus hijas/os.

Maternal mental health problems during pregnancy, childbirth, and the postpartum period are a challenge for public health. Not recognizing them hinders a timely diagnosis and treatment and has an impact on the mother and the establishment of the fundamental bond of the mother-child dyad. We must recognize the risk factors (age, socioeconomic status, mental health history, family dysfunction, unfavorable environment), clinical manifestations, and screening tools. There is evidence that the effect of stress, anxiety, and depression during pregnancy negatively affect fetal neurodevelopment and condition child developmental outcomes. Here we describe the negative impact of postpartum depression during the first months of life, which affects mother-child bonding, postnatal development (emotional, behavioral, cognitive, language), and the maintenance of breastfeeding. We also recognize protective factors that mitigate its effects. It is essential to establish preventive strategies and interdisciplinary diagnostic and therapeutic approaches to minimize the risks to the mother and her children.

RESUMEN

Las fracturas con hundimiento de cráneo sin una explicación clara sobre su origen orientan al traumatismo con un objeto romo y a la sospecha de maltrato infantil. En el caso de los bebés recién nacidos, su corta edad es un factor de vulnerabilidad y obliga a una exhaustiva evaluación. Ante la sospecha de maltrato infantil, resulta importante evaluar los diagnósticos diferenciales para realizar la intervención más adecuada posible. Es necesario evitar tanto intervenciones excesivas como omitir la intervención que sea necesaria. Las fracturas craneales deprimidas congénitas, descritas como "fracturas pingpong", son raras (0,3 a 2/10 000 partos). Pueden aparecer sin antecedentes traumáticos o en partos instrumentalizados. Se describe en este artículo el caso de un recién nacido con una fractura ping-pong como ejemplo de una fractura no intencional.

Depressed skull fractures without a clear explanation as to their origin point to trauma with a blunt object and suspected child abuse. In the case of newborn infants, their young age is a vulnerability factor and requires an exhaustive assessment. When child abuse is suspected, an assessment of the differential diagnoses is required to make the most appropriate intervention possible. Both an excessive intervention and an omission of a necessary intervention should be avoided. Congenital depressed skull fractures, described as "ping-pong fractures", are rare (0.3 to 2/10 000 births). They may appear without any trauma history or in instrumentalized childbirth. Here we describe the case of a newborn infant with a ping-pong fracture as an example of an accidental fracture.

RESUMEN

Abstract Background: The administration of colostrum through its absorption at the oropharyngeal level stimulates the mucosa-associated lymphoid tissue, providing a local immunological protection barrier. The study aimed to investigate the association of oropharyngeal colostrum administration with the reduction of inflammatory indices. Materials and methods: This was an observational, ambispective, analytical study of newborns < 32 weeks of gestation at risk of sepsis. Oropharyngeal colostrum was administered at 0.2 mL every 4 h for 5 days. Inflammatory indices were analyzed. Statistical analysis included frequencies, percentages, mean and Standard deviation, contingency coefficient, and Kolmogorov–Smirnov test for the distribution curve of the numerical data. Results: There were 50 patients, 33 (66%) female and 17 (34%) male, with a median gestational age of 30-31 weeks (95% confidence interval [CI]). Nineteen patients had sepsis. A lower positivity rate in C-reactive protein was found, with a median of 0.5-0.6 (95% CI) at 5 days of colostrum administration versus 0.5-1.1 (95% CI) as the initial C-reactive protein. Analysis with χ2 yielded a p = 0.13, and the contingency coefficient showed a p = 0.196, indicating an association. Conclusion: Oropharyngeal colostrum administration was associated with a lower C-reactive protein positivity rate and clinical improvement in premature newborns at risk of sepsis.

RESUMEN

Objetivo: Determinar si es posible predecir la valoración del recién nacido según el estado nutricional materno a través de un modelo de árbol de decisión. Métodos: Estudio analítico transversal. Se revisaron 326 historias clínicas de gestantes de un hospital público peruano, 2021. Se valoró el recién nacido mediante el puntaje APGAR, edad gestacional al nacer, peso al nacer, peso y talla para la edad gestacional. El estado nutricional materno incluyó el índice de masa corporal pregestacional y la ganancia de peso gestacional. La predicción se realizó mediante un modelo de aprendizaje automático supervisado denominado "árbol de decisión". Resultados: No fue posible predecir mediante el estado nutricional materno, el puntaje APGAR al minuto y la talla para la edad gestacional. La probabilidad de tener edad gestacional a término al nacer es de 97,2 % cuando la ganancia de peso gestacional es > 5,4 Kg (p = 0,007). Las probabilidades más altas de peso adecuado al nacer fueron con ganancia de peso gestacional entre 4,5 Kg (p < 0,001) y 17 Kg (p < 0,001) y con índice de masa corporal pregestacional ≤ 36,523 Kg/m2 (p = 0,004). Finalmente, la mayor probabilidad de peso adecuado para la edad gestacional es cuando la ganancia de peso gestacional es ≤ 11,8 Kg (p < 0,001) y con un índice de masa corporal pregestacional ≤ 36,523 Kg/m2 (p = 0,005). Conclusiones: Es posible predecir la valoración del recién nacido a partir del estado nutricional materno mediante un aprendizaje automático(AU)

Objective: To determine whether it is possible to predict the assessment of the newborn according to maternal nutritional status through a decision tree model. Methods: Cross-sectional analytical study. A total of 326 medical records of pregnant women from a Peruvian public hospital were reviewed, in 2021. The newborn was assessed using the APGAR score, gestational age at birth, birth weight, weight and height for gestational age. Maternal nutritional status included pregestational body mass index and gestational weight gain. The prediction was made using a supervised machine learning model called a "decision tree." Results: The APGAR score at one minute and height for gestational age were not possible to predict by maternal nutritional status. The probability of having full-term gestational age at birth is 97.2% when gestational weight gain is > 5.4 kg (p = 0.007). The highest probabilities of adequate birth weight were with gestational weight gain between 4.5 kg (p < 0.001) and 17 kg (p < 0.001) and with pregestational body mass index ≤ 36.523 kg/m2 (p = 0.004). Finally, the highest probability of adequate weight for gestational age is when gestational weight gain is < 11.8 Kg (p < 0.001) and with a pregestational body mass index ≤ 36.523 Kg/m2 (p = 0.005). Conclusions: It is possible to predict the assessment of the newborn based on the mother's nutritional status using machine learning(AU)

RESUMEN

Introduction: Child health is conditioned by the circumstances of pregnancy, childbirth, and early life. Objective: To describe the maternal and neonatal characteristics of live births (LBs) in the Information System on Live Births of Santa Catarina (SC), Brazil. Materials and methods: A cross-sectional study describedthe maternal and neonatal characteristics of 940,059 LBs, from 2010 to 2019. Pearson's chi-square test and Fisher's exact test were conducted, with a statistical significance level of p < 0.05. Results: The mean values of maternal age, number of live children, and number of fetal deaths as well as abortions were 27.1 years, 0.9, and 0.2, respectively. The averages of the number of gestation weeks, number of prenatal consultations, the start date of the prenatal care, and birth weight were 38.5 weeks, 8.1 months, 2.5 monthsand 3,217.1 grams, respectively. Low birth weight (LBW) was prevalent among mothers without education (p < 0.001), including those without prenatal visits (p < 0.001). A higher prevalence of being underweight was observed among female neonates (p < 0.001) and with a maternal age of ≥ 40 years (10.8%; p < 0.001) compared to newborns with good vitality. Newborns with good vitality had a low prevalence of underweight (p < 0.001). The frequency of the variables studied increased, comparing the beginning and end of the period and whether the differences are statistically significant. Conclusions: The study draws attention to the need for interventions to improve the indicators that determine LBW(AU)

RESUMEN

INTRODUCTION: Transfontanellar brain ultrasound is an essential tool for monitoring the size of the ventricles in preterm neonates and has many advantages over other alternative diagnostic techniques, including its accessibility and non-use of ionizing radiation. When considering the normal ventricular size, it is essential to have reference measurements based on age-matched populations. The objective of this article is to present our reference measures, based on a sample of preterm infants that we have studied. METHODS: A retrospective observational study was conducted. Measurements of the Levene index, frontal horn thickness, and Evans index were obtained in preterm neonates from 25 to 45 weeks, over a period of 5 years, between January 2016 and December 2020. After applying the exclusion criteria, a sample of 199 patients and 350 ultrasound scans were obtained. The independent samples t-test and the Mann-Whitney test were used for the comparison of samples. RESULTS: The distribution of the right and left Levene indices was normal (Shapiro-Wilk test with p = 0.16 and 0.05, respectively), unlike the thickness distribution of the frontal horns (p < 0.05 on both sides). No significant differences were detected between the sexes (p = 0.08). A linear correlation was found between the biparietal diameter and the Levene index. CONCLUSION: From the results obtained in our study, we present reference tables for ventricular size, with the 3rd, 25th, 50th, 75th, and 97th, being the first ones made in our country.

RESUMEN

Superior mesenteric artery syndrome (SMAS) is a rare cause of duodenal obstruction which is characterized by compression of the duodenum due to narrowing of the space between the superior mesenteric artery and aorta. Incomplete duodenal obstruction due to SMAS in neonates is rarely reported in the literature. In this case, it is a full-term 2-day-old male with the complaint of recurrent vomiting starting soon after birth. The patient was diagnosed with SMAS and duodenoduodenostomy was performed. Accompanying Meckel's diverticulum was excised.

El síndrome de la arteria mesentérica superior (SMAS) es una causa rara de obstrucción duodenal que se caracteriza por la compresión del duodeno debido al estrechamiento del espacio entre la arteria mesentérica superior y la aorta. La obstrucción duodenal incompleta por SMAS en recién nacidos rara vez se informa en la literatura. En este caso se trata de un varón de 2 días nacido a término que presenta vómitos recurrentes desde poco después del nacimiento. El paciente fue diagnosticado de SMAS y se le realizó duodenoduodenostomía. Se extirpó el divertículo de Meckel que lo acompañaba.

Objective: understand the perception of mothers about open visitation in the neonatal intensive care unit. Methods: descriptive, qualitative study, carried out through semi-structured and individualized interviews, in a public maternity hospital located in the interior of São Paulo, Brazil, in 2019. The sample was defined by the data saturation method and consisted of 14 mothers. Data were submitted to Thematic Content Analysis. Results: two categories were listed: showing the benefits of open visitation and challenges to be overcome. The benefits included the satisfaction of staying with the child, participating in care, strengthening the maternal bond, monitoring the baby's evolution, showing the quality of care and affective involvement, reducing negative feelings and visiting the father at night. On the other hand, the challenges included the impossibility of staying with the child, being present only at preestablished times to receive information from doctors, prioritizing it in relation to that provided by nurses, receiving partial information, being afraid to express doubts and experience negative feelings. Conclusion: the findings of this study provide support for the health team and managers to promote the adherence of mothers to open visitation in neonatal intensive care units. (AU)

RESUMEN

INTRODUCTION: . Neonatal screening of glutaric aciduria type 1 (GA-1) has brought radical changes in the course and outcomes of this disease. This study analyses the outcomes of the first 5 years (2015-2019) of the AGA1 neonatal screening programme in our autonomous community. MATERIAL: . We conducted an observational, descriptive and retrospective study. All neonates born between January 1, 2015 and December 31, 2019 that participated in the neonatal screening programme were included in the study. The glutarylcarnitine (C5DC) concentration in dry blood spot samples was measured by means of tandem mass spectrometry applying a cut-off point of 0.25 µmol/L. RESULTS: . A total of 30 120 newborns underwent screening. We found differences in the C5DC concentration based on gestational age, type of feeding and hours of life at sample collection. These differences were not relevant for screening purposes. There were no differences between neonates with weights smaller and greater than 1500 g. Screening identified 2 affected patients and there were 3 false positives. There were no false negatives. The diagnosis was confirmed by genetic testing. Patients have been in treatment since diagnosis and have not developed encephalopathic crises in the first 4 years of life. CONCLUSIONS: . Screening allowed early diagnosis of two cases of GA-1 in the first 5 years since its introduction in our autonomous community. Although there were differences in C5DC levels based on gestational age, type of feeding and hours of life at blood extraction, they were not relevant for screening.

RESUMEN

BACKGROUND: Evaluating the ABO/RhD blood group and the direct antiglobulin Coombs test (DAT) at birth is recommended good practice, but there is variability in its universal implementation. This study aims to show the comparative results in various variables of clinical impact during the hospital stay of neonates with positive DAT compared with those with negative DAT, based on the systematic detection of the ABO/RhD group and DAT at birth. METHODS: Newborns between 2017 and 2020 in a high-risk pregnancy care hospital were included. The ABO/RhD and DAT group was determined in umbilical cord samples or the first 24 hours of life. Demographic, maternal, and neonatal variables were recorded. The association between the variables was estimated using the odds ratio (OR). RESULTS: 8721 pairs were included. The DAT was positive in 239 newborns (2.7%), with the variables associated with positive PDC being maternal age > 40 years (OR: 1.5; 95% CI: 1.0 to 2.3), birth by cesarean section (1.4; 1.1-2.0), mother group O (6.4; 3.8-11.8), prematurity (3.6; 2.6-5.0), birth weight < 2500 g (2.1; 1.6-2.8), newborn group A (15.7; 10.7-23.1) and group B (17.6; 11.4-27.2), hemoglobin at birth < 13.5 g/dl (4.5; 2.8-7.1) and reticulocytosis > 9% (1.9; 1.2 to 3.1). DISCUSSION: The frequency of neonatal positive PDC was 2.7%, with a significant association with maternal/neonatal incompatibility to the ABO and RhD group, with a substantial impact on various neonatal variables. These results support the policy of universal implementation at the birth of the ABO/RhD and DAT determination.

INTRODUCCIÓN: La determinación del grupo sanguíneo ABO/RhD y la prueba directa de Coombs (PDC) al nacimiento son una práctica recomendada, pero existe variabilidad en su implementación universal. Se presentan los resultados de la determinación al nacimiento del grupo ABO/RhD y la PDC en una cohorte institucional. MÉTODOS: Se incluyeron los recién nacidos entre 2017 y 2020 en un hospital de atención a embarazos de alto riesgo. Se determinó el grupo ABO/RhD y se realizó la PDC en muestras de cordón umbilical o en las primeras 24 horas de vida. Se registraron las variables demográficas, maternas y neonatales. Se estimó la asociación entre las variables mediante la razón de probabilidad (OR). RESULTADOS: Se incluyeron 8721 binomios.

RESUMEN

INTRODUCTION: Hypoxic-ischaemic encephalopathy is a clinical syndrome of neurological dysfunction that occurs immediately after birth following an episode of perinatal asphyxia. We conducted a scoping review to assess the methodological quality of clinical practice guidelines that address this condition. METHODOLOGY: We conducted the evaluation using the AGREE II tool. High methodological quality was defined as a score greater than 70% in every domain. RESULTS: The analysis included three clinical practice guidelines; the highest scores were in the scope and purpose domain (84.26%; SD, 14.25%) and the clarity of presentation domain (84.26%; SD, 17.86%), while the lowest score corresponded to the applicability domain (62.50%; SD, 36.62%). Two guidelines were classified as high quality and one guideline as low-quality. CONCLUSIONS: Two of the assessed guidelines were classified as being of high quality; however, the analysis identified shortcomings in the applicability domain, in addition to methodological variation between guidelines developed in middle- or low-income countries versus high-income countries. Efforts are needed to make high-quality guidelines available to approach the management of hypoxic-ischaemic encephalopathy in newborns.

RESUMEN

Introducción: la población indígena es vulnerable y poco se conoce sobre sus indicadores somatométricos y APGAR al nacimiento. Objetivo: explorar la asociación de la condición de recién nacido indígena (RNI) sobre parámetros somatométricos y APGAR al nacimiento. Métodos: estudio transversal exploratorio que empleó el registro de recién nacidos (RN) de una clínica privada. La condición de RNI se determinó por la condición indígena materna. Se consideraron la puntuación APGAR al primer minuto y los indicadores nutricionales derivados del peso, la talla y los perímetros. El análisis estadístico empleó regresiones logísticas. Resultados: el análisis exploratorio involucró a 7413 RN (1,8 % de RNI). El 52 % de los RN eran de sexo masculino y el 8,1 % fueron pretérmino (< 37 semanas). Los RNI, respecto a los RN no indígenas, presentaron mayor riesgo de desnutrición (8 % vs. 6,3 %; p < 0,001), mayor exceso de peso (7,3 % vs. 1,8 %; p < 0,001), menor perímetro cefálico (33,6 cm vs. 34,1 cm; p = 0,017), menor perímetro abdominal (30,9 cm vs. 31,5 cm; p = 0,011) y bajo puntaje APGAR < 7 (8,7 % vs. 1,2 %). La condición de indígena se asoció de manera independiente con el bajo peso (< 2500 g) al nacimiento (OR: 0,4; IC 95 %: 0,2; 0,9), perímetro cefálico en exceso (OR: 2,7; IC 95 %: 1,5; 4,7) y puntaje de APGAR < 7 puntos (OR: 8,3; IC 95 %: 4,2; 16,5). Conclusiones: la condición de indígena se asocia con indicadores que impactan negativamente en la salud de los recién nacidos, como son el perímetro cefálico y el bajo desempeño en la escala APGAR. Estos resultados deben tomarse como un llamado para mejorar la atención prenatal de la población indígena.(AU)

Introduction: the indigenous population is vulnerable and there is limited understanding of their somatometric indicators and APGAR score at birth. Aim: the objective of the study was to explore the association of the condition of indigenous newborn (INB) on somatometric parameters and APGAR score at birth. Methods: this study employed an exploratory cross-sectional design, utilizing the registry of newborns (NB) from a private clinic. The APGAR score at one minute after birth, as well as nutritional indicators derived from measurements of weight, height, and perimeters, were taken into consideration. The statistical analysis involved the use of logistic regressions. Results: the analysis included 7413 NB (1.8 % INB), 52 % were male and 8.1 % were born preterm (gestational age < 37 weeks). In comparison to non-indigenous NB, the INB group showed a higher risk of malnutrition (8 % vs. 6.3 %; p < 0.001), a greater prevalence of excess weight (7.3 % vs. 1.8 %; p < 0.001), smaller head circumference (33.6 cm vs. 34.1 cm; p = 0.017), smaller abdominal circumference (30.9 cm vs. 31.5 cm; p = 0.011), and a higher occurrence of low APGAR scores (< 7) (8.7 % vs. 1.2 %; p < 0.001). Furthermore, the indigenous condition was independently associated with low birth weight (< 2.500 g) (OR, 0.4; 95 % CI, 0.2; 0.9), excess head circumference (OR, 2.7; 95 % CI, 1.5; 4.7), and APGAR score < 7 points (OR, 8.3; 95 % CI, 4.2; 16.5). Conclusions: the indigenous condition was associated with factors that have adverse effects on the health of NB, including reduced head circumference and suboptimal performance on the APGAR scale. These results emphasize the importance of improving access to and quality of prenatal healthcare services for indigenous communities.(AU)

RESUMEN

Introducción: La enterocolitis necrotizante (ECN) es una enfermedad potencialmente mortal que afecta a los neonatos, y frente a laque la leche materna ha demostrado tener un papel protector. Administrando lipopolisacáridos (LPS) por vía oral en ratas recién nacidas(RRN), hemos desarrollado un modelo experimental para inducir undaño intestinal similar al que provoca la ECN con objeto de evaluarel aspecto macroscópico y microscópico del intestino, y de ese modo,analizar la presencia de ECN y estudiar el papel que desempeña laleche materna (LM). Material y métodos: Las RRN se dividieron en tres grupos: el grupoA (control, n= 10) permaneció con su madre; el grupo B (LPS, n=25)fue aislado tras el nacimiento, alimentado por sonda con una fórmulaespecial para ratas y LPS oral, y sometido a estrés (hipoxia tras sonda);y el grupo C (LM, n= 12) fue alimentado con leche materna tras elnacimiento y posteriormente aislado y sometido a estrés al igual que elgrupo B. El día 4 se sacrificó a las RRN y se recuperaron sus intestinospara su posterior evaluación. Resultados: En el grupo de control, no se observó ECN ni macroscópica ni histológicamente, mientras que los dos grupos sometidos aestrés (B y C) presentaron una incidencia global de la ECN del 73%.La mayoría de los sujetos del grupo B desarrollaron signos histológi-cos de ECN (85%), y los del grupo C registraron una incidencia de laECN estadísticamente menor (50%, p= 0,04), lo que significa que laLM desempeña una función protectora frente a la ECN (OR= 0,19; IC95%: 0,40-0,904). Conclusión: Nuestro modelo reveló una incidencia significativa dela ECN en RRN (73%), desempeñando la LM la misma función protectora que en el caso de los humanos recién nacidos, lo que significa que estemodelo experimental de ECN es fiable y reproducible. Gracias a dichologro, podremos investigar nuevos y potenciales objetivos terapéuticospara una peligrosa enfermedad que, a día de hoy, carece de tratamiento.(AU)

Introduction: Necrotizing enterocolitis (NEC) is a life-threateningcondition that afflicts neonates. Breastfeeding has demonstrated to playa protective role against it. By administering lipopolysaccharides (LPS)orally in newborn rats (NBR), we have developed an experimental modelto induce NEC-like gut damage. Our aim was to assess the macroscopicand microscopic appearance of the gut, to evaluate the presence of NECand study the role of breast milk (BM). Material and methods: NBR were divided into 3 groups: GroupA (control, n= 10) remained with the mother, group B (LPS, n= 25)was isolated after birth, gavage-fed with special rat formula and oralLPS, then submitted to stress (hypoxia after gavage) and group c (BM,n= 12) was breastfed once after birth, then isolated, and submitted tostress like group B. On day 4, NBR were sacrificed, and intestine washarvested and assessed. Results: In the control group NEC was not present either macroscopically or histologically. Both groups submitted to stress (B and C)presented a global incidence of NEC of 73%. Most of group B developedhistologic signs of NEC (85%) and group C showed a statistically lowerincidence of NEC (50%, p= 0.04), playing the BM a protective roleagainst NEC (OR= 0.19; 95% CI: 0.40- 0.904)Conclusion: Our model showed a significant incidence of NEC inNBR (73%) with the same protective role of BM as in newborn humans,achieving a reliable and reproducible experimental NEC model. This willallow us to investigate new potential therapeutic targets for a devastatingdisease that currently lacks treatment.(AU)

RESUMEN

INTRODUCTION: Our aim was to determine which foetal or neonatal growth curves discriminate the probability of dying of newborns with low birth weight for their gestational age (small for gestational age, SGA) and sex (weight < 10th percentile) and to establish the curves that are presumably most useful for monitoring growth through age 10 years. MATERIAL AND METHODS: The analysis included every neonate (15 122) managed in our hospital (2013-2022) and all neonates born preterm before 32 weeks (6913) registered in the SEN1500 database (2019-2022). We considered most useful those curves with the highest likelihood ratio (LR) for dying with or without a history of SGA in each subgroup of gestational ages. Theoretically, the optimal curves for monitoring growth would be those with a higher R2 in the quantile regression formulas for the 50th percentile. RESULTS: The growth curves exhibiting the strongest association between SGA and hospital mortality are the Intergrowth fetal curves and the Fenton neonatal curves in infants born preterm before 32 weeks. However, the optimal curves for premature babies and neonates overall were those of Olsen and Intergrowth. The most useful curves to monitor anthropometric values alone until age 10 years of age are the longitudinal Intergrowth curves followed by the WHO standards, but if a single reference is desired from birth through age 10 years, the best option is the Fenton curves followed by the WHO standards. CONCLUSIONS: The Intergrowth reference provides the most discriminating foetal growth curves. In neonatal clinical practice, the optimal references are the Fenton followed by the WHO charts.

RESUMEN

Resumen Introducción: La determinación del grupo sanguíneo ABO/RhD y la prueba directa de Coombs (PDC) al nacimiento son una práctica recomendada, pero existe variabilidad en su implementación universal. Se presentan los resultados de la determinación al nacimiento del grupo ABO/RhD y la PDC en una cohorte institucional. Métodos: Se incluyeron los recién nacidos entre 2017 y 2020 en un hospital de atención a embarazos de alto riesgo. Se determinó el grupo ABO/RhD y se realizó la PDC en muestras de cordón umbilical o en las primeras 24 horas de vida. Se registraron las variables demográficas, maternas y neonatales. Se estimó la asociación entre las variables mediante la razón de probabilidad (OR). Resultados: Se incluyeron 8721 binomios. La PDC fue positiva en 239 recién nacidos (2.7%), siendo las variables asociadas a la PDC positiva la edad materna > 40 años (OR: 1.5;IC95%: 1.0-2.3), el nacimiento por vía cesárea (1.4; 1.1-2.0), la madre del grupo O (6.4; 3.8-11.8), la prematuridad (3.6; 2.6-5.0); el peso al nacer < 2500 g (2.1; 1.6-2.8); el neonato del grupo A (15.7; 10.7-23.1) o del grupo B (17.6; 11.4-27.2), la hemoglobina al nacer < 13.5 g/dl (4.5; 2.8-7.1) y la reticulocitosis > 9% (1.9; 1.2 a 3.1). Discusión: La frecuencia de PDC positiva neonatal es del 2.7%, con asociación significativa la incompatibilidad materna/neonatal al grupo ABO y RhD, con impacto significativo en diversas variables neonatales. Estos resultados apoyan la política de implementación universal al nacimiento de la determinación de ABO/RhD y PDC.

Abstract Background: Evaluating the ABO/RhD blood group and the direct antiglobulin Coombs test (DAT) at birth is recommended good practice, but there is variability in its universal implementation. This study aims to show the comparative results in various variables of clinical impact during the hospital stay of neonates with positive DAT compared with those with negative DAT, based on the systematic detection of the ABO/RhD group and DAT at birth. Methods: Newborns between 2017 and 2020 in a high-risk pregnancy care hospital were included. The ABO/RhD and DAT group was determined in umbilical cord samples or the first 24 hours of life. Demographic, maternal, and neonatal variables were recorded. The association between the variables was estimated using the odds ratio (OR). Results: 8721 pairs were included. The DAT was positive in 239 newborns (2.7%), with the variables associated with positive PDC being maternal age > 40 years (OR: 1.5; 95% CI: 1.0 to 2.3), birth by cesarean section (1.4; 1.1-2.0), mother group O (6.4; 3.8-11.8), prematurity (3.6; 2.6-5.0), birth weight < 2500 g (2.1; 1.6-2.8), newborn group A (15.7; 10.7-23.1) and group B (17.6; 11.4-27.2), hemoglobin at birth < 13.5 g/dl (4.5; 2.8-7.1) and reticulocytosis > 9% (1.9; 1.2 to 3.1). Discussion: The frequency of neonatal positive PDC was 2.7%, with a significant association with maternal/neonatal incompatibility to the ABO and RhD group, with a substantial impact on various neonatal variables. These results support the policy of universal implementation at the birth of the ABO/RhD and DAT determination.

RESUMEN

Objective. To determine the prevalence, types, and associated risk factors of congenital anomalies in newborns admitted to Isidro Ayora Gynecological-Obstetric Hospital in Quito, Ecuador, between 2009-2022. Methods. Cross-sectional study, using retrospective data from the Perinatal Information System database. Chi-square tests and simple and multiple binary logistic regression models were employed. R programming language was utilized. Results. A total of 26,236 newborns were studied, of which 11.7% (3,075) were diagnosed with congenital anomalies. The most common were those related to the nervous system (25.6%), cardiorespiratory system (21.1%), and musculoskeletal system (16.1%). Maternal age over 35 years, pregnancy planning, and multiple pregnancies were associated with the presence of congenital anomalies. When analyzing risk factors by affected system, maternal age, maternal history of abortions and diabetes, folic acid consumption, and newborn's sex had both favorable and unfavorable effects on the development of congenital anomalies in a specific system. Conclusions. This study investigated the prevalence and most common types of congenital anomalies, along with their associated risk factors, in a reference hospital. These findings were compared with reports from other regions. The results provide significant data on the epidemiology of congenital anomalies in the studied population, which can guide the development of preventive strategies. The need for further comprehensive research on this topic in the region is emphasized.
