Sulfato de magnesio antenatal y eliminación tardía de meconio: Estudio multicéntrico / Antenatal magnesium sulphate and delayed passage of meconium: A multicentre study

Introducción: La relación entre sulfato de magnesio (MgSO4) y el retraso en la evacuación de meconio presenta resultados controvertidos en la literatura. Objetivos: Determinar si existe relación entre la administración de MgSO4 a la madre y la eliminación tardía de meconio (ETM) en el neonato y conocer los niveles de magnesio en sangre en estos, con respecto a la dosis acumulada de MgSO4 administrada a la madre. Población y métodos: Estudio descriptivo-analítico, en pacientes ≤ 32 semanas de edad gestacional, con diseño retrospectivo-prospectivo, llevado a cabo en dos hospitales de tercer nivel asistencial. Se definió la ETM como retraso en la evacuación meconial ≥ 48 horas y/o necesidad de estimulación rectal en ≥ 2 ocasiones para realizar deposición y/o retraso ≥ 48 horas entre la primera y segunda deposición. Resultados: Se reclutaron 283 pacientes (204 retrospectiva y 79 prospectivamente), de los cuales 152 (53,7%) presentó ETM. No se encontró relación entre la administración de MgSO4 a la madre, ni la dosis acumulada de MgSO4 en esta, ni los niveles de magnesio en sangre del neonato con la presencia de ETM. La mayor edad gestacional (OR 0,8, IC 0,69-0,93, p = 0,003) resultó factor protector independiente de la ETM y la necesidad de reanimación avanzada (OR 2,24, IC 1,04-4,86, p = 0,04) factor de riesgo. Conclusiones: Los niveles alcanzados de magnesio en sangre del neonato con las dosis de MgSO4 administradas a las madres, no se relacionan con la ETM. La menor edad gestacional y la necesidad de reanimación avanzada predicen mayor riesgo de ETM. (AU)

Introduction: The published evidence on the association between magnesium sulphate (MgSO4) and delayed passage of meconium (DPM) is contradictory. Objectives: To determine whether there is an association between the administration of MgSO4 to the mother and DPM in the neonate, and to analyse serum magnesium levels in neonates in relation to the cumulative dose of MgSO4 administered to the mother. Population and methods: Retrospective and prospective descriptive and analytical study conducted in patients delivered at or before 32 weeks of gestation in 2 tertiary care hospitals. Delayed passage of meconium was defined as failure to pass meconium within 48 hours of birth and/or need for rectal stimulation on 2 or more occasions to pass stool and/or interval of at least 48 hours between the first and second bowel movements. Results: The study included 283 patients (204 retrospectively and 79 prospectively), of who 152 (53.7%) experienced DPM. Delayed passage of meconium was not associated with antenatal MgSO4 administration, the cumulative maternal MgSO4 dose or neonatal serum magnesium levels. Older gestational age (OR, 0.8; confidence interval [CI], 0.69–0.93; P = .003) was an independent protective factor against DPM, while the need for advanced resuscitation (OR, 2.24; CI 1.04–4.86; P = .04) was a risk factor for DPM. Conclusion: The neonatal serum levels of magnesium reached with the doses of MgSO4 administered to mothers were not associated with DPM. Lower gestational age and the need for advanced resuscitation were predictors associated with an increased risk of DPM. (AU)

Impact of Gestational COVID-19 on Neonatal Outcomes: Is Vertical Infection Possible?

BACKGROUND: The vertical transmission of severe acute respiratory coronavirus-2 (SARS-CoV-2) remains highly debated. Here, we evaluated SARS-CoV-2-transmission in newborns with intrauterine conditions. METHODS: This was a prospective, observational and multicentric study involving 13 Spanish hospitals included in the GEStational and NEOnatal-COVID cohort. Pregnant women with microbiologically confirmed SARS-CoV-2 infection during any trimester of pregnancy or delivery and their newborns were included from March to November 2020. Demographic, clinical and microbiological data were also obtained. Viral loads were analyzed in different maternal and newborn biological samples (placenta, breast milk and maternal blood; urine, meconium and newborn blood). RESULTS: A total of 177 newborns exposed to SARS-CoV-2 were included. Newborns were tested by reverse transcriptase-polymerase chain reaction using nasopharyngeal swabs within the first 24-48 hours of life and at 14 days of life. In total 5.1% were considered to have SARS-CoV-2 infection in the neonatal period, with 1.7% considered intrauterine and 3.4% intrapartum or early postnatal transmission cases. There were no differences in the demographic and clinical characteristics of the pregnant women and their newborns' susceptibility to infections in their perinatal history or background. CONCLUSIONS: Intrauterine transmission of SARS-CoV-2 is possible, although rare, with early postnatal transmission occurring more frequently. Most infected newborns remained asymptomatic or had mild symptoms that evolved well during follow-up. We did not find any maternal characteristics predisposing infants to neonatal infection. All infected newborn mothers had acute infection at delivery.Although there was no presence of SARS-CoV2 in cord blood or breast milk samples, SARS-CoV-2 viral load was detected in urine and meconium samples from infected newborns.

Training, experience and need of booster courses in neonatal cardiopulmonary resuscitation. Survey to pediatricians.

INTRODUCTION: The resuscitation of the newborn in the delivery room requires high capacities and occurs frequently in an unexpected way. Many professionals trained in pediatrics as pediatric residents will work posteriorly in pediatric units with delivery rooms and will perform neonatal resuscitation only occasionally. Skills acquired in practice or resuscitation courses deteriorate over time. MATERIAL AND METHODS: Descriptive observational study through a survey to pediatricians trained in neonatology at a tertiary hospital in Madrid, and who completed their residency period between 2009 and 2016. Questions about their training in resuscitation and their usual work in the delivery room. RESULTS: Out of 179 surveys sent, 140 pediatricians (78,2%) answered it. 73.6% took a training course in neonatal resuscitation during the residency. There was a progressive increase in the number of residents who did the course during the study period. 74.3% have worked after residency in assistance at birth. 40.7% have taken a refresher course in neonatal resuscitation. CONCLUSIONS: Training in neonatal resuscitation has increased and been consolidated during the training process for pediatric residents. A high percentage of pediatricians work after residency in pediatric units with delivery rooms, less than half of these professionals having been recycled in neonatal resuscitation. Recycling and periodic training seem interesting options to improve the performance of these professionals in the delivery room.

Prenatal therapy with magnesium sulphate and intestinal obstruction due to meconium in preterm newborns.

INTRODUCTION: Magnesium sulphate (MgSO4) therapy has shown to be useful as a neurological protector in the preterm newborn below 32 weeks of gestation. The most documented adverse effect is cardiorespiratory failure, whereas its relationship with meconium obstruction is controversial. The main objective of this study was to analyse the possible association between prenatal MgSO4 therapy and meconium obstruction. PATIENTS AND METHODS: An analytical retrospective study was conducted on <32 weeks preterm babies admitted to a tertiary-level hospital (January 2016-December 2017). Epidemiological, prenatal and postnatal data on the outcomes were obtained, analysed and compared in both groups (exposed to MgSO4 and not exposed). RESULTS: The study included 201 patients (146 exposed and 55 non-exposed). There were no significant differences in the mean gestational age (28.4 ±â€¯2.2 vs. 28.7 ±â€¯2.8 weeks, respectively), or in the rest of epidemiological and perinatal variables. Prenatal corticosteroid therapy was more frequent in the MgSO4 group (75.9 vs. 53.7%; p = .002), and in the non-exposed group there were more multiple pregnancies (52.7 vs. 36.6%; p = .027), and female gender (56.4 vs. 37%; p = .013). There were no statistically significant differences in the presence of meconium obstruction (75.9% in exposed vs. 67.3% in non-exposed; p = .23), although repeated rectal stimulation was more frequent in the exposed group (43.2 vs. 27.9%; p = .08). Furthermore, there were no significant differences in the main cardiorespiratory variables: 1-min Apgar score (6.2 in MgSO4- exposed vs. 5.6 in non-exposed; p = .75), 5-min Apgar score (7.9 vs. 7.6; p = .31), advanced newborn resuscitation (26 vs. 31.5%; p = .44), maximum FiO2 (45.5 vs. 48; p = .58), and initial inotropic requirements (10.3 vs. 20.8%; p = .55). CONCLUSIONS: This study found no correlations between MgSO4 therapy and meconium obstruction or cardiorespiratory failure.

Formación, experiencia y necesidad de reciclaje en reanimación neonatal. Encuesta a pediatras / Training, experience and need of booster courses in neonatal cardiopulmonary resuscitation. Survey to pediatricians

Introducción: La reanimación del recién nacido en sala de partos requiere altas capacidades y se produce con frecuencia de manera inesperada. Muchos profesionales formados en pediatría mediante el método de residencia trabajarán a posteriori en unidades pediátricas con paritorio y realizarán reanimación neonatal solo de forma ocasional. Las competencias adquiridas en la práctica o los cursos de reanimación se deterioran con el tiempo. Material y métodos: Estudio descriptivo observacional a través de una encuesta a pediatras formados en Neonatología de un hospital terciario de Madrid y que finalizaron su residencia entre los años 2009 y 2016. Preguntas acerca de su formación en reanimación y su trabajo habitual en paritorio. Resultados: Ciento cuarenta pediatras contestaron la encuesta de 179 encuestas enviadas (78,2%). El 73,6% realizó un curso de formación en reanimación neonatal durante la residencia, objetivándose un incremento progresivo en el número de residentes que lo realizaron durante el período de estudio. El 74,3% ha trabajado tras la residencia en la asistencia al nacimiento. El 40,7% ha realizado algún curso de reciclaje en reanimación neonatal. Conclusiones: Ha aumentado y se ha consolidado la formación en reanimación neonatal durante el proceso de formación de residentes de Pediatría. Un alto porcentaje de pediatras trabajan tras la residencia en Unidades Pediátricas con paritorio, habiéndose reciclado menos de la mitad de esos profesionales en reanimación neonatal. El reciclaje y el entrenamiento periódico parecen opciones interesantes para mejorar la actuación de estos profesionales en sala de partos.(AU)

Terapia prenatal con sulfato de magnesio y obstrucción intestinal por meconio en recién nacidos pretérmino / Prenatal therapy with magnesium sulphate and intestinal obstruction due to meconium in preterm newborns

Introducción: El sulfato de magnesio (SMg) ha demostrado eficacia como neuroprotector en pretérminos < 32 semanas. Su efecto adverso más documentado es la depresión cardiorrespiratoria, siendo dudosa su relación con la obstrucción meconial. El objetivo principal del estudio es analizar la posible asociación entre el SMg antenatal y la obstrucción meconial. Pacientes y métodos: Estudio retrospectivo analítico, de neonatos < 32 semanas de edad gestacional ingresados en un hospital terciario (enero del 2016 a diciembre del 2017). Se recogieron datos epidemiológicos, perinatales y de evolución posnatal, comparando expuestos y no expuestos a SMg. Resultados: Se incluyeron 201 pacientes (146 recibieron SMg y 55 no). No existieron diferencias en la edad gestacional media (28,4 ± 2,2 vs. 28,7 ± 2,8 semanas, respectivamente), ni en el resto de variables epidemiológicas y perinatales, salvo en expuestos, la administración más frecuente de corticoides antenatales (75,9 vs. 53,7%; p = 0,002), y en no expuestos el parto múltiple (52,7 vs. 36,6%; p = 0,027), y el sexo femenino (56,4 vs. 37%; p = 0,013). No hubo diferencias significativas en la obstrucción meconial (75,9% expuestos vs. 67,3% no expuestos; p = 0,23), aunque la estimulación rectal repetida fue más frecuente en el grupo tratado (43,2 vs. 27,9%; (p = 0,08). Tampoco hubo diferencias en las principales variables de depresión cardiorrespiratoria: Apgar al primer minuto 6,2 vs. 5,6 en expuestos y no expuestos, respectivamente (p = 0,75) y a los cinco minutos 7,9 vs. 7,6 (p = 0,31), reanimación avanzada 26 vs. 31,5% (p = 0,44), FiO2 máxima 45,5 vs. 48 (p = 0,58) y necesidad inicial de inotrópicos 10,3 vs. 20,8% (p = 0,55). Conclusiones: El presente estudio no halló asociación entre la administración de SMg y la obstrucción meconial o la depresión cardiorrespiratoria. (AU)

TBL1XR1 associated intellectual disability, a new missense variant with dysmorphic features plus autism: Expanding the phenotypic spectrum.

Missense and frameshift pathogenic variants and microdeletions involving TBL1XR1 gene have been described in patients with intellectual disability, autism, Rett-like features and schizophrenia, some of them with the clinical diagnosis of Pierpont syndrome, a rare pattern of multiple congenital anomalies, but others without dysmorphic findings or with non-specific ones, and also patients with only some of the features associated with Pierpont syndrome. We here present a case with a de novo novel missense variant in TBL1XR1 gene with overlapping features with Pierpont syndrome and autism, a neurobehavioral manifestation not previously reported in Pierpont syndrome. This patient expands the phenotypic spectrum of TBL1XR1 gene pathogenic variants.

Long-term outcomes of preterm infants treated with less invasive surfactant technique (LISA).

OBJECTIVE: The aim of this study is to compare the clinical outcomes at 24 months postmenstrual age of two populations receiving beractant replacement therapy using less invasive surfactant administration (LISA) versus intubation, administration of surfactant, and early extubation (INSURE). Hospital admission requirements, psychomotor development, and respiratory and neurological outcomes were studied. STUDY DESIGN: This was a single-center, retrospective, and descriptive study with a sample of 60 patients (30 for each group) on nasal continuous positive airway pressure during the first 3 days of life, requiring surfactant administration. RESULTS: We found no significant differences between both groups on psychomotor development and respiratory and neurological outcomes. CONCLUSION: Compared to INSURE technique, the administration of surfactant by LISA is feasible and safe and reduces invasive mechanical ventilation exposure with no differences in the follow-up neurodevelopmental and respiratory outcomes at 24 postmenstrual age.

Detección de factores de riesgo de reingreso prevenible en la hospitalización pediátrica / Detection of risk factors for preventable paediatric hospital readmissions

Introducción y objetivos: La tasa de reingresos hospitalarios es un indicador de calidad de la asistencia hospitalaria. El objetivo de este trabajo es describir factores de riesgo de reingreso prevenible en la hospitalización pediátrica. Material y métodos: Estudio analítico, retrospectivo, unicéntrico realizado en las plantas de Pediatría de un hospital terciario (junio de 2012 a noviembre de 2015). Se definió reingreso al que acontecía en los primeros 30 días del ingreso previo: muy precoz (en menos de 48 h), precoz (2-7 días) y tardío (a partir de 7 días). Se definió reingreso prevenible al que ocurrió en los primeros 15 días y por la misma causa del primer ingreso. Se analizaron variables epidemiológicas y clínicas. Se realizó un estudio univariante y posteriormente multivariante. Resultados: En el período de estudio ingresaron en las plantas de Pediatría General Hospitalaria 5.459 pacientes y reingresaron 226 (tasa de reingreso del 4,1%). Cuando la tasa de ocupación hospitalaria es mayor del 70%, el porcentaje global de reingresos es significativamente mayor (8,5 vs. 2,5%), p < 0,001. En el análisis de regresión de Cox se objetivó que la presencia de enfermedad de base y el número de visitas a urgencias desde el alta son factores de predicción de reingreso prevenible. Conclusiones: La tasa de reingresos es mayor en los períodos de mayor presión asistencial. El reingreso de los pacientes con patología crónica de base es prevenible, y por lo tanto hay que diseñar estrategias para intentar evitarlo

Introduction and objectives: Readmission rate is an indicator of the quality of hospital care. The aim of the study is to identify potential preventable factors for paediatric readmission. Material and methods: A descriptive, analytical, longitudinal, and single centre study was carried out in the Paediatric Hospitalisation ward of a tertiary hospital during the period from June 2012 to November 2015. Readmission was defined as the one that occurs in the first 30 days of previous admission, as very early readmission if it occurs in the first 48 hours, early readmission in the 2-7 days, and late readmission if occurs after 7 days. Preventable readmission is defined as one that takes place in the first 15 days and for the same reason as the first admission. Epidemiological and clinical variables were analysed. A univariate and multivariate study was carried out. Results: In the study period, 5,459 patients were admitted to the paediatric hospital, of which 226 of them were readmissions (rate of readmission: 4.1%). When the hospital occupation rate was greater than 70%, the overall percentage of readmissions was significantly higher (8.5% vs 2.5%; P < .001). In the multivariate analysis, it was found that having a chronic disease and the number of visits to emergency care units before admission, are predictive factors of preventable readmission. Conclusions: The rate of readmissions is greater in the periods of higher care pressure. The readmission of patients with chronic condition is preventable, and therefore strategies must be designed to try to avoid them
