NT-PROBNP as a screening tool for low-risk patent ductus arteriousus: a follow-up validation study.

The purpose of the study is to test whether NT-proBNP serves as a screening tool for low-risk patent ductus arteriosus and safely avoids routine early echocardiography. This is a prospective observational study in preterm infants ≤32 weeks of gestational age. Infants with ≥5100 pg/ml (positive screening) at 48-72 hours of life received comprehensive echocardiography and were treated according to shunt severity. Infants with NT-proBNP below 5100 pg/ml (negative screening) were managed expectantly. The main outcome was need for ductus treatment within the first 7 days of life. One hundred twenty-five infants were included; 82 had a negative NT-proBNP screening and 43 had a positive NT-proBNP screening. No infant (0%) with a negative screening was treated for ductus while 26 (60.4%) with a positive screening were treated (p < 0.001). NT-proBNP avoided a 65.6% of routine echocardiograms. NT-proBNP had an excellent performance to predict PDA treatment (AUC = 0.967).Conclusion: NT-proBNP at 48-72 hours of life has an excellent performance to detect low risk and avoids unnecessary echocardiograms. This may contribute to optimize PDA management in terms of resource utilization.

Effects of Maternal Stress on Breast Milk Production and the Microbiota of Very Premature Infants.

Perinatal stress experienced by mothers of very premature newborns may influence the mother's milk and the infant's intestinal microbiota. This prospective study of mothers of very preterm infants fed with mother's own milk (MOM) was carried out in a tertiary hospital over a 2-year period. The assessment of maternal stress in 45 mothers of 52 very preterm newborns using the parental stress scale (PSS:NICU) revealed an inverse relationship between stress and MOM production in the first days of life (p = 0.012). The greatest contributor to stress was the one related to the establishment of a mother-child bond. Maternal stress was lower in mothers in whom the kangaroo method was established early (p = 0.011) and in those with a higher educational level (p = 0.032). Levels of fecal calprotectin (FC) decreased with the passage of days and were directly correlated with birthweight (p = 0.044). FC levels 7 days post-delivery were lower in newborns that received postnatal antibiotics (p = 0.027). High levels of maternal stress resulted in progressive decreases and increases in the proportions of Firmicutes and Proteobacteria species, respectively, over 15 days post-delivery, both in MOM and in fecal samples from premature newborns. These findings underscore the importance of recognizing and appropriately managing maternal stress in neonatal units, given its marked influence on both the microbiota of maternal milk and the intestinal microbiota of premature newborns.

Niveles asistenciales en las unidades neonatales en España: Una visión actualizada para una nueva realidad / Care levels in neonatal units in Spain: An updated vision for a new reality

La Sociedad Española de Neonatología estableció en el año 2013 los niveles asistenciales de las unidades neonatales en España. Desde entonces, la natalidad en nuestro país, así como la universalización del conocimiento, de las técnicas y de los dispositivos de tratamiento de los pacientes ha evolucionado significativamente. Esta situación obliga a una redefinición de los actuales niveles asistenciales basándose en criterios de calidad que permitan una mejor comparabilidad entre las unidades y supongan un impulso para la mejora en la atención de nuestros recién nacidos.

Recomendaciones para la transfusión de hemoderivados en neonatología / Recommendations for transfusion of blood products in neonatology

La escasa evidencia sobre el uso de las transfusiones en neonatología explica las limitaciones de las guías clínicas actuales. A pesar de ello, en este documento analizamos la evidencia más reciente para hacer unas recomendaciones para la práctica clínica. La prevención de la anemia de la prematuridad, el uso de protocolos y las indicaciones restrictivas de transfusión, componen la mejor estrategia para nuestros clínicos. En las transfusiones de plaquetas, es preciso valorar el riesgo de sangrado, integrando la situación clínica y analítica. Por último, el plasma fresco congelado está recomendado en neonatos con coagulopatía y sangrado activo, en déficits congénitos de factores sin tratamiento específico y en situaciones de coagulación intravascular diseminada. Todos los hemoderivados presentan efectos adversos que deben hacernos evaluar individual y minuciosamente la necesidad de una transfusión. (AU)

The scant evidence on the use of transfusions in neonatal care explains the limitations of current clinical guidelines. Despite this, in this document we explore the most recent evidence to make recommendations for the clinical practice. The prevention of anaemia of prematurity, the use of protocols and restrictive transfusion strategies constitute the best approach for clinicians in this field. In the case of platelet transfusions, the risk of bleeding must be assessed, combining clinical and laboratory features. Lastly, fresh frozen plasma is recommended in neonates with coagulopathy and active bleeding, with congenital factor deficiencies for which there is no specific treatment or with disseminated intravascular coagulation. All blood products have adverse effects that warrant a personalised and thorough assessment of the need for transfusion. (AU)

Perinatal palliative care.

Perinatal Palliative Care is a model of care designed to prevent and treat the physical, spiritual, emotional, and social needs of fetuses and newborn infants with life-threatening or life-limiting conditions. The care extends to the infant's family. It is delivered by an interdisciplinary team to improve the quality of life from the time of diagnosis (possibly in utero) into death and bereavement (days, months or years later). To guarantee the access of this vulnerable population to high quality palliative care, structured programs and protocols need to be further developed in tertiary hospitals that treat highly complex obstetric and neonatal pathologies. Basic training is required for all the professionals involved.

Cuidados paliativos perinatales / Perinatal palliative care

Los cuidados paliativos perinatales son una forma de atención clínica diseñada para anticipar, prevenir y tratar el sufrimiento físico, psicológico, social y espiritual de los fetos y recién nacidos con enfermedades limitantes o amenazantes de la vida, que se extiende a sus familias. Se trata de una atención interdisciplinaria y coordinada que busca ofrecer la mejor calidad de vida posible, desde el diagnóstico (muchas veces intraútero) hasta el fallecimiento y el duelo (días, meses o años después). Los cuidados paliativos perinatales constituyen una prestación de salud básica dirigida a una población particularmente vulnerable. Para garantizar el acceso a una atención de calidad es esencial desarrollar programas estructurados y protocolos clínicos en todos los hospitales terciarios que atienden patología obstétrica y neonatal de alta complejidad. Se requiere también una formación básica de todos los profesionales implicados.(AU)

Sedoanalgesia in neonatal units.

Pain recognition and management continues to be a challenge for health professionals in Neonatal Intensive Care Units. Many of the patients are routinely exposed to repeated painful experiences with demonstrated short- and long-term consequences. Preterm babies are a vulnerable high-risk population. Despite international recommendations, pain remains poorly assessed and managed in many Neonatal Intensive Care Units. Due to there being no general protocol, there is significant variability as regards the guidelines for the approach and treatment of pain between the different Neonatal Intensive Care Units. The objective of this article is to review and assess the general principles of pain in the initial stages of development, its recognition through the use of standardised scales. It also includes its prevention and management with the combination of pharmacological and non-pharmacological measures, as well as to establish recommendations that help alleviate pain in daily clinical practice by optimising pain and stress control in the Neonatal Intensive Care Units.

Sedoanalgesia en las unidades neonatales / Sedoanalgesia in neonatal units

El reconocimiento del dolor y su tratamiento en las unidades de cuidados intensivos neonatales continúa siendo un desafío para los profesionales sanitarios responsables de la atención de estos niños. Las exposiciones dolorosas repetidas a las que se someten muchos de estos pacientes de manera rutinaria han demostrado presentar efectos deletéreos a corto y largo plazo. Los recién nacidos prematuros, especialmente vulnerables, suponen una población de alto riesgo. Pese a las recomendaciones internacionales, el dolor sigue siendo evaluado actualmente en muchas ocasiones de manera inconsistente, sin protocolización, siendo patente, además, entre las diferentes unidades de cuidados intensivos neonatales una variabilidad importante en cuanto a las pautas para el abordaje y tratamiento del mismo.El objetivo de este artículo es revisar y valorar los principios generales del dolor en las etapas iniciales del desarrollo, su reconocimiento mediante el uso de escalas protocolizadas, y su prevención y manejo, con la combinación de medidas farmacológicas y no farmacológicas; con el fin de establecer recomendaciones que ayuden a aliviar el dolor en la práctica clínica diaria optimizando el control del dolor y el estrés en las unidades de cuidados intensivos neonatales.

Validation of an IGF1 Screening Method for Retinopathy of Pre-maturity.

Retinopathy of pre-maturity (ROP) is a retinal disease that causes arrest of vascularization of the retina and can result in retinal detachment and blindness. Current screening protocols may not be sufficiently accurate to identify all at-risk patients. The aim of this study is to validate a method for improved identification of newborns at risk of ROP. We conducted a prospective clinical trial of pre-term newborns <32 weeks of gestation and/or <1,500 g birth weight during a 6-year period in a tertiary care hospital. We applied our new method based on measurement of insulin-like growth factor 1 (IGF1) levels at 3 weeks of age and the presence of sepsis during the first 3 weeks of life. Our screening protocol allowed exclusion of 121 (79.1%) patients for whom American Academy of Pediatrics (AAP) guidelines recommended screening, had a negative predictive value of 100%, and correctly identified all patients with ROP. Following retrospective assessment of our data based on these findings, we propose further restriction of the current AAP indications for screening to <1,100 g and <28 weeks of gestation in order to improve diagnostic efficacy while ensuring optimal use of restriction of human and material resources.

Parto domiciliario: un fenómeno creciente con potenciales riesgos / Home births: A growing phenomenon with potential risks

El parto extrahospitalario es un tema controvertido que genera dudas a obstetras y pediatras sobre su seguridad. El nacimiento hospitalario fue la pieza clave en la reducción de la mortalidad materna y neonatal. Esta reducción en la mortalidad ha derivado en considerar el embarazo y el parto como fenómenos seguros, lo que, unido a una mayor conciencia social de la necesidad de humanización de estos procesos, ha conducido a un aumento en la demanda del parto domiciliario. Estudios en países como Australia, Holanda y Reino Unido muestran que el parto en casa puede aportar ventajas para la madre y el recién nacido, pero es necesario que se dote de los suficientes medios materiales, que sea atendido por profesionales formados y acreditados, y que se encuentre perfectamente coordinado con las unidades de obstetricia y neonatología hospitalarias, para poder garantizar su seguridad. En nuestro medio, no hay suficientes datos de seguridad ni evidencia científica que avalen el parto domiciliario en la actualidad

Home birth is a controversial issue that raises safety concerns for paediatricians and obstetricians. Hospital birth was the cornerstone to reduce maternal and neonatal mortality. This reduction in mortality has resulted in considering pregnancy and childbirth as a safe procedure, which, together with a greater social awareness of the need for the humanisation of these processes, have led to an increase in the demand for home birth. Studies from countries such as Australia, the Netherlands, and United Kingdom show that home birth can provide advantages to the mother and the newborn. It needs to be provided with sufficient material means, and should be attended by trained and accredited professionals, and needs to be perfectly coordinated with the hospital obstetrics and neonatology units, in order to guarantee its safety. Therefore, in our environment, there are no safety data or sufficient scientific evidence to support home births at present

Rapid Phenotype-Driven Gene Sequencing with the NeoSeq Panel: A Diagnostic Tool for Critically Ill Newborns with Suspected Genetic Disease.

New genomic sequencing techniques have shown considerable promise in the field of neonatology, increasing the diagnostic rate and reducing time to diagnosis. However, several obstacles have hindered the incorporation of this technology into routine clinical practice. We prospectively evaluated the diagnostic rate and diagnostic turnaround time achieved in newborns with suspected genetic diseases using a rapid phenotype-driven gene panel (NeoSeq) containing 1870 genes implicated in congenital malformations and neurological and metabolic disorders of early onset (<2 months of age). Of the 33 newborns recruited, a genomic diagnosis was established for 13 (39.4%) patients (median diagnostic turnaround time, 7.5 days), resulting in clinical management changes in 10 (76.9%) patients. An analysis of 12 previous prospective massive sequencing studies (whole genome (WGS), whole exome (WES), and clinical exome (CES) sequencing) in newborns admitted to neonatal intensive care units (NICUs) with suspected genetic disorders revealed a comparable median diagnostic rate (37.2%), but a higher median diagnostic turnaround time (22.3 days) than that obtained with NeoSeq. Our phenotype-driven gene panel, which is specific for genetic diseases in critically ill newborns is an affordable alternative to WGS and WES that offers comparable diagnostic efficacy, supporting its implementation as a first-tier genetic test in NICUs.
