Depresión puerperal: impacto en la madre gestante y en el desarrollo físico, emocional y cognitivo posnatal de sus hijas/os. Una mirada ecológica / Postpartum depression: Impact on pregnant women and the postnatal physical, emotional, and cognitive development of their children. An ecological perspective

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.

Fractura craneal deprimida congénita ("fractura ping-pong") en neonatos como diagnóstico diferencial de maltrato físico / Congenital depressed skull fracture ("ping-pong" fracture) in newborn infants as a differential diagnosis of physical abuse

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.

Prevalencia de osteopenia del prematuro antes y después de la implementación de una estrategia temprana de manejo fosfocálcico / Prevalence of osteopenia of prematurity before and after implementing an early strategy with the use of calcium and phosphate

Introducción. Con el uso de la nutrición parenteral agresiva en recién nacidos de muy bajo peso, se detectaron alteraciones del metabolismo fosfocálcico. En 2016 se implementó una estrategia de prevención a través del monitoreo fosfocálcico y su suplementación temprana. El objetivo fue estudiar si esta estrategia disminuye la prevalencia de osteopenia e identificar factores de riesgo asociados. Población y métodos. Estudio cuasiexperimental que comparó la prevalencia de osteopenia entre dos grupos: uno después de implementar la estrategia de monitoreo y suplementación fosfocálcica (01/01/2017-31/12/2019), y otro previo a dicha intervención (01/01/2013-31/12/2015). Resultados. Se incluyeron 226 pacientes: 133 pertenecen al período preintervención y 93 al posintervención. La prevalencia de osteopenia global fue del 26,1 % (IC95% 20,5-32,3) y disminuyó del 29,3 % (IC95% 21,7-37,8) en el período preintervención al 21,5 % (IC95% 13,6-31,2) en el posintervención, sin significancia estadística (p = 0,19). En el análisis multivariado, el puntaje NEOCOSUR de riesgo de muerte al nacer, recibir corticoides posnatales y el período de intervención se asociaron de manera independiente a osteopenia. Haber nacido luego de la intervención disminuyó un 71 % la probabilidad de presentar fosfatasa alcalina >500 UI/L independientemente de las restantes variables incluidas en el modelo. Conclusión. La monitorización y suplementación fosfocálcica precoz constituye un factor protector para el desarrollo de osteopenia en recién nacidos con muy bajo peso al nacer.

Introduction. With the use of aggressive parenteral nutrition in very low birth weight infants, alterations in calcium and phosphate metabolism were detected. In 2016, a prevention strategy was implemented through calcium phosphate monitoring and early supplementation. Our objective was to study whether this strategy reduces the prevalence of osteopenia and to identify associated risk factors. Population and methods. Quasi-experiment comparing the prevalence of osteopenia between two groups: one after implementing the calcium phosphate monitoring and supplementation strategy (01/01/2017­12/31/2019) and another prior to such intervention (01/01/2013­12/31/2015). Results. A total of 226 patients were included: 133 in the pre-intervention period and 93 in the post-intervention period. The overall prevalence of osteopenia was 26.1% (95% CI: 20.5­32.3) and it was reduced from 29.3% (95% CI: 21.7­37.8) in the pre-intervention period to 21.5% (95% CI: 13.6­31.2) in the post-intervention period, with no statistical significance (p = 0.19). In the multivariate analysis, the NEOCOSUR score for risk of death at birth, use of postnatal corticosteroids, and the intervention period were independently associated with osteopenia. Being born after the intervention reduced the probability of alkaline phosphatase > 500 IU/L by 71%, regardless of the other variables included in the model. Conclusion. Calcium phosphate monitoring and early supplementation is a protective factor against the development of osteopenia in very low birth weight infants.

Comparison between the 2009­2013 and 2014­2018 five-year periods

Introducción. El consumo de sustancias psicoactivas ilegales en el embarazo constituye un problema creciente. En pocas maternidades latinoamericanas se aplica una estrategia de detección y los datos publicados son escasos. Objetivos. Comparar dos quinquenios de resultados de una estrategia de detección de sustancias psicoactivas ilegales implementada en el posparto. Población y métodos. Estudio de corte transversal. Detección por inmunoensayo en orinas de binomios madre-hijo/a, en un hospital público argentino entre 2009 y 2018. Resultados. En 76/191 binomios se detectaron sustancias en 10 años. El criterio de detección más frecuente fue la comunicación o antecedente de uso de drogas: 25/37 y 32/39 en cada quinquenio. Predominaron cannabis (21/37 y 26/39) y cocaína (19/37 y 16/39) en ambos períodos. No hubo diferencias en datos demográficos, ginecológicos, del embarazo ni neonatales en los quinquenios comparados. Conclusiones. No se encontraron diferencias en la frecuencia ni en el tipo de sustancias detectadas a lo largo de 10 años.

Introduction. The use of illicit psychoactive substances during pregnancy is a growing problem. Few Latin American maternity centers implement a screening strategy, and published data are scarce. Objectives. To compare the outcomes of 2 five-year periods of a postpartum strategy to screen for illicit psychoactive drugs. Population and methods. This was a cross-sectional study. Immunoassay detection in urine of mothernewborn infant dyads in an Argentine public hospital between 2009 and 2018. Results. Substances were detected in 76/191 dyads over 10 years. The most frequent detection criterion was reporting or history of drug use: 25/37 and 32/39 in each five-year period. Cannabis (21/37 and 26/39) and cocaine (19/37 and 16/39) predominated in both periods. No differences were observed in demographic, gynecological, pregnancy, or neonatal data between both five-year periods. Conclusions. No differences were found in the frequency or type of substances detected over 10 years

Potenciales evocados auditivos de tronco en neonatos nacidos a gran altitud / Brainstem auditory evoked potentials in newborn infants born in a high-altitude area

Introducción. Una forma no invasiva y segura de evaluar los parámetros neurofisiológicos en recién nacidos es la evaluación de los potenciales evocados auditivos del tronco encefálico (PEAT). Objetivo. Evaluar las latencias e intervalos de ondas de los PEAT en neonatos sanos nacidos a gran altitud (Cusco, 3399 msnm). Población y métodos. Estudio transversal y prospectivo. Se incluyeron neonatos menores a 14 días de vida, dados de alta a menos de 7 días de nacidos, evaluados para determinar los valores de los PEAT a intensidades sonoras de 70 dB, 80 dB y 90 dB. Se incluyeron las variables edad gestacional, peso al nacer, tipo de parto. Se calcularon las diferencias de las medianas de las latencias e intervalos de las ondas según edad gestacional y peso al nacer. Resultados. Se evaluaron 96 neonatos (17 pretérminos). Las medianas de las latencias de las ondas I a V a 90 dB fueron las siguientes: onda I 1,56 ms; onda II 2,74 ms; onda III 4,37 ms; onda IV 5,62 ms, onda V 6,63 ms. La latencia de la onda I para 80 dB fue de 1,71 ms y para 70 dB de 1,88 ms. Los intervalos para las ondas (I-III), (III-V) y (I-V) fueron de 2,8 ms, 2,2 ms y 5,0 ms respectivamente, sin diferencias entre intensidades (p >0,05). La prematuridad y el bajo peso estuvieron asociados a latencias de la onda I más prolongadas (p <0,05). Conclusiones. Se presentan valores ajustados de latencias e intervalos de los PEAT en neonatos nacidos a gran altitud. Se identificó que, a distintas intensidades sonoras, se ven diferencias en las latencias de las ondas, pero no en los intervalos entre ondas.

Introduction. A non-invasive and safe way to assess neurophysiological parameters in newborn infants is the evaluation of brainstem auditory evoked potentials (BAEPs). Objective. To assess the latencies and wave intervals of BAEPs in healthy newborn infants born in a high-altitude area (Cusco, 3399 MASL). Population and methods. Cross-sectional and prospective study. Newborn infants younger than 14 days of age, discharged less than 7 days after birth, were assessed to determine BAEP values at intensities of 70 dB, 80 dB, and 90 dB. The study variables were gestational age, birth weight, and type of delivery. The median differences in wave latencies and intervals were estimated according to gestational age and birth weight. Results. A total of 96 newborn infants (17 preterm infants) were assessed. The median latencies of waves I­V at 90 dB were for wave I: 1.56 ms, wave II: 2,74 ms, wave III: 4.37 ms, wave IV: 5.62 ms, and wave V: 6.63 ms. The latency of wave I for 80 dB was 1.71 ms and for 70 dB, 1.88 ms. Wave intervals (I­III, III­V, I­V) were 2.8 ms, 2.2 ms, and 5.0 ms, respectively, without differences among intensities (p > 0.05). Prematurity and low birth weight were associated with a longer wave I latency (p < 0.05). Conclusions. Here we describe adjusted BAEP latency and interval values for newborn infants born at high altitude. At different sound intensities, we identified differences in wave latencies, but not in interwave intervals.

Factors associated with cholestasis in newborns with gastroschisis / Fatores associados à colestase em recém-nascidos com gastrosquise

ABSTRACT Objective: To describe the incidence and to analyze risk factors associated with cholestasis in neonates with gastroschisis. Methods: This is a retrospective cohort study in a tertiary single center analyzing 181 newborns with gastroschisis between 2009 and 2020. The following risk factors associated with cholestasis were analyzed: gestational age, birth weight, type of gastroschisis, silo closure or immediate closure, days of parenteral nutrition, type of lipid emulsion, days of fasting, days to reach a full diet, days with central venous catheter, presence of infections, and outcomes. Results: Among the 176 patients evaluated, 41 (23.3%) evolved with cholestasis. In the univariate analysis, low birth weight (p=0.023), prematurity (p<0.001), lipid emulsion with medium-chain triglycerides and long-chain triglycerides (p=0.001) and death (p<0.001) were associated with cholestasis. In the multivariate analysis, patients who received lipid emulsion with fish oil instead of medium chain triglycerides/long chain triglycerides (MCT/LCT) emulsion had a lower risk of cholestasis. Conclusions: Our study shows that lipid emulsion with fish oil is associated with a lower risk of cholestasis in neonates with gastroschisis. However, this is a retrospective study and a prospective study should be performed to confirm the results.

RESUMO Objetivo: Analisar a incidência e os fatores de risco associados à colestase em recém-nascidos com gastrosquise. Métodos: Estudo de coorte retrospectivo em um único centro terciário, que analisou 181 recém-nascidos com gastrosquise entre 2009 e 2020. Foram examinados os seguintes fatores de risco associados à colestase: idade gestacional, peso ao nascer, tipo de gastrosquise, fechamento com silo ou fechamento imediato, dias de uso nutrição parenteral, tipo de emulsão lipídica, dias de jejum, dias para atingir a dieta completa, dias com cateter venoso central, presença de infecções e desfechos. Resultados: Dos 176 pacientes avaliados, 41 (23,3%) evoluíram com colestase. Baixo peso ao nascer (p=0,023), prematuridade (p<0,001), emulsão lipídica com triglicerídeos de cadeia média e triglicerídeos de cadeia longa (p=0,001) e óbito (p<0,001) foram associados à colestase. Na análise multivariada, os pacientes que receberam emulsão lipídica com óleo de peixe em vez da emulsão diária de triglicérides de cadeia média/triglicérides de cadeia longa (MCT/LCT) apresentaram menor risco de colestase. Conclusões: Nosso estudo mostra que a emulsão lipídica com óleo de peixe está associada a menor risco de colestase em neonatos com gastrosquise, porém este é um estudo retrospectivo, e um estudo prospectivo deve ser realizado para confirmar os resultados.

Based on the evidence over the past 18 years, the guidelines are updated from the aspects of the prevention, risk assessment, intervention, and follow-up of hyperbilirubinemia in the newborn infants with a gestational age of ≥35 weeks. This article gives an interpretation of the key points in the guidelines, so as to safely reduce the risk of bilirubin encephalopathy and unnecessary intervention.

Factors Predicting Early Major Adverse Events in the Intensive Care Unit After Successful Cardiac Surgery for Congenital Heart Disease in Full-Term Neonates

ABSTRACT Objective: In this study, we aimed to evaluate the factors affecting major adverse event (MAE) development after full-term neonatal cardiac surgery. Methods: This study was conducted retrospectively on newborns who underwent congenital heart surgery between June 1, 2020, and June 1, 2022. MAE was defined as the presence of at least one of the following: cardiac arrest, unplanned reoperation, emergency chest opening, admission to the advanced life support system, and death. The role of blood lactate level, vasoactive inotropic score (VIS), and cerebral near-infrared spectroscopy (NIRS) changes in predicting MAE was investigated. Results: A total of 240 patients (50% male) were operated during the study period. The median age of patients was seven days (interquartile range 3-10 days). MAE was detected in 19.5% of the cases. Peak blood lactate levels >7 mmol/liter (area under the curve [AUC] 0.72, 95% confidence interval [CI] [0.62-0.82], P<0.001, sensitivity 76%, specificity 82%, positive predictive value [PPV] 88%) was an independent risk factor for MAE (odds ratio [OR] 2.7 [95% CI 1.3-6]). More than 30% change in NIRS value during the operative period (AUC 0.84, 95% CI [0.80-0.88], P<0.001, sensitivity 65%, specificity 85%, PPV 90%) was a strong predictor of MAE. VIS > 10 was an independent risk factor (AUC 0.75, 95% CI [0.70-0.84], P<0.001, sensitivity 86%, specificity 80%, PPV 84%) and strongly predicted MAE (OR 1.4 [95% CI 0.9-5]). Conclusion: Cerebral NIRS changes > 30%, high blood lactate levels, and VIS score within the 48 hours may help to predict the development of MAE in the postoperative period.

Mortalidad en recién nacidos de muy bajo peso al nacer en la Red Neonatal NEOCOSUR: causalidad y temporalidad / Mortality in very low birth weight (VLBW) infants in South American NEOCOSUR Neonatal Network: timing and causes

Introducción. La mortalidad de los recién nacidos de muy bajo peso de nacimiento (RNMBPN) se ha mantenido en ~26 % en los últimos 16 años en la Red Neonatal NEOCOSUR. Objetivo. Determinar la causa de muerte de los RNMBPN y su temporalidad en el período 20072016 en la Red Neonatal NEOCOSUR. Población y métodos. Estudio observacional de cohorte multicéntrica; análisis retrospectivo de datos obtenidos prospectivamente. Se incluyeron recién nacidos entre 24 y 31+6 semanas de edad gestacional y peso de nacimiento de 500-1500 g, en 26 centros de la Red Neonatal NEOCOSUR. Las causas de muerte se analizaron según ocurriera en sala de partos (SP) o durante la estadía en la unidad de cuidados intensivos neonatales (UCIN). La edad posnatal de muerte se determinó a través de análisis de Kaplan-Meier. Resultados. Se incluyeron un total de 11.753 RNMBPN con una mortalidad global del 25,6 %. Las causas de muerte predominantes en SP fueron malformaciones congénitas (43,3 %), enfermedades respiratorias (14,3 %) y prematuridad (11,4 %). Las causas de muerte predominantes en UCIN fueron las respiratorias (24,2 %) e infecciosas (24,1 %). La edad promedio de muerte fue de 10,2 días y mediana de 4 días. El 10,2 % de las muertes ocurrieron en SP; el 21,5 %, durante el primer día; el 52 % ocurrió en los primeros 4 días y el 63,8 %, durante la primera semana de vida. Conclusiones. Se encuentran importantes diferencias en las causas de muerte de RNMBPN según ocurra en SP o en UCIN. Las infecciosas y respiratorias son las más relevantes luego del ingreso a la unidad de cuidados intensivos.

Introduction. Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network. Objective. To determine the cause of death of VLBWIs and its temporality in the 2007-2016 period in the NEOCOSUR Neonatal Network. Population and methods. Observational, multicenter cohort study; retrospective analysis of data collected prospectively. Newborn infants born between 24 and 31+6 weeks of gestation age with a birth weight between 500 and 1500 g in the 26 sites of the NEOCOSUR Neonatal Network were included. The causes of death were analyzed depending on whether they occurred in the delivery room (DR) or in the neonatal intensive care unit (NICU). The postnatal age at time of death was determined using the KaplanMeier test. Results. A total of 11 753 VLBWIs were included; overall mortality was 25.6%. The prevailing causes of death in the DR were congenital malformations (43.3%), respiratory diseases (14.3%), and prematurity (11.4%). The prevailing causes of death in the NICU were respiratory diseases (24.2%) and infections (24.1%). The average and median age at death were 10.2 and 4 days, respectively. Also, 10.2% of deaths occurred in the DR; 21.5% on day 1, 52% in the first 4 days, and 63.8% in the first week of life. Conclusions. Important differences were observed in the causes of death of VLBWIs depending on their occurrence in the DR or the NICU. Infectious and respiratory conditions were the most relevant factors following admission to the NICU.

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.

Confiabilidade de instrumentos de avaliação de retração de cintura escapular em uma unidade de cuidados intermediários neonatal / Reliability of the evaluation of shoulder girdle retraction instrument in a neonatal intermediate unit care

OBJETIVO: Avaliar a confiabilidade inter e intraexaminador, na utilização de instrumentos de avaliação da retração de cintura escapular em crianças internadas em uma unidade de cuidados intermediários neonatal. MATERIAL E MÉTODOS: Estudo quantitativo, transversal e observacional, realizado com recém-nascidos e lactentes que necessitaram de internamento em uma unidade de cuidados intermediários neonatal. A coleta de dados ocorreu de outubro de 2019 a fevereiro de 2020. Para avaliação da retração da cintura escapular foi utilizado um protocolo de inspeção biomecânica elaborado pelas pesquisadoras, que possibilitou a realização de medidas (em centímetros) das bordas mediais superiores e inferiores, direita e esquerda, até a coluna vertebral, com a cabeça em rotação para a direita e para a esquerda, e o sinal do cachecol. As avaliações foram realizadas sempre pelos mesmos avaliadores. Para estimar a confiabilidade inter e intraexaminador do protocolo de inspeção biomecânica e sinal do cachecol, foi utilizado o Índice de Kappa e para as medidas do posicionamento das escápulas, o Coeficiente de Correlação Intraclasse. RESULTADOS: O protocolo de inspeção biomecânica dos sinais sugestivos de retração de cintura escapular demostrou concordância leve a moderada interexaminadores, e substancial a quase perfeita intraexaminador. A concordância interexaminadores obtida no sinal do cachecol foi leve a moderada, e quase perfeita intraexaminador. O posicionamento das escápulas apresentou concordância interexaminadores considerada como boa, e concordância excelente intraexaminador. CONCLUSÃO: A avaliação de sinais sugestivos de retração de cintura escapular, em recém-nascidos e lactentes, apresenta baixos índices confiabilidade interexaminadores e altíssima confiabilidade intraexaminador

OBJECTIVE: To evaluate inter and intra-examiner reliability in the use of instruments to assess shoulder girdle retraction in children hospitalized in a neonatal intermediate care unit. METHODS: Quantitative, cross-sectional and observational study carried out with newborns and infants who required hospitalization in a neonatal intermediate care unit. Data collection took place from October 2019 to February 2020. To evaluate shoulder girdle retraction, a biomechanical inspection protocol developed by the researchers was used, which made it possible to measure (in centimeters) from the upper and lower medial edges, right and left, to the spine, with the head in rotation to the right and left, and the scarf sign. The evaluations were always carried out by the same evaluators. To estimate inter and intra-examiner reliability of the biomechanical inspection protocol and scarf signal, the Kappa Index was used and, for measurements of scapular positioning, the Intraclass Correlation Coefficient. RESULTS: The biomechanical inspection protocol for suggestive signs of scapular girdle retraction showed mild to moderate inter-examiner agreement and substantial to almost perfect intra-examiner agreement. The intra-examiner agreement obtained in the scarf sign was mild to moderate and almost perfect intra-examiner. The positioning of the scapulae showed good inter-examiner agreement and excellent intra-examiner agreement. CONCLUSION: The evaluation of suggestive signs of scapular girdle retraction in newborns and infants has low inter-examiner reliability and very high intra-examiner reliability.

Analysis of influencing factors for the occurrence of neonatal scalp hematoma / 中国实用护理杂志

Objective:To discuss the influencing factors of neonatal scalp hematoma, and provide a basis for reducing the occurrence of neonatal scalp hematoma.Methods:Retrospectively analyzed the data of 13 151 parturients and their newborn infants who delivered in the Hangzhou Women′s Hospital from January to December 2020, counted the incidence of neonatal scalp hematoma, and Logistic regression analysis was used to analyze its influencing factors.Results:Among 13 151 newborn baby, 68 cases of neonatal head hematoma occurred, the incidence was 0.52%. Vaginal delivery, forceps, intraspinal analgesia were statistically significant in the occurrence of neonatal scalp hematoma ( χ2=19.26, 19.59, 6.11, all P<0.05). Conclusions:Vaginal delivery, forceps, and intraspinal analgesia are the risk factors for neonatal scalp hematoma. Lateral perineal incision during delivery did not reduce the incidence of neonatal scalp hematoma. In this study, many cases of neonatal scalp hematoma occurred before the crown of the fetal head. Labor management, improve the rate of non-drug analgesia, promote natural delivery, early detection, early prevention, and reduce the incidence of neonatal hematoma.

Efecto de la velocidad de crecimiento intrahospitalaria en la somatometría a los 2 años en niños con peso de nacimiento menor de 1500 gramos / Effect of intrahospital growth rate on somatometric measurements at 2 years old in children with a birth weight of less than 1500 grams

Objetivo. Determinar la asociación de la velocidad de crecimiento (VC) intrahospitalaria y la fortificación de leche humana con la somatometría y el riesgo de muerte tras el alta o discapacidad grave a los 2 años de edad corregida (EC). Población y método. Análisis retrospectivo de la VC y evolución posterior. Se incluyeron los recién nacidos del período 1990-2015, con peso al nacer < 1500 g. Se excluyeron neonatos con patología que afectaba al crecimiento. Se estudió una cohorte global y dos subcohortes: los nacidos en 1990-2001 (sin fortificación) y los nacidos en 2002-2015 (fortificada). La VC se calculó según la fórmula de Fenton y se consideró adecuada si resultó > 12 g/kg/día. Resultados. Se reclutaron 1194 pacientes. La VC adecuada se asoció a mayor mediana de peso a los 2 años de EC en la cohorte global (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0,02. La cohorte 2002-2015 alcanzó mayor talla media (86,42 ± 4,03 cm versus 85,56 ± 4,01, p = 0,02) y mayor porcentaje de prematuros que alcanzaron un crecimiento compensatorio (catch-up) a los 2 años de EC en la cohorte global con VC adecuada (62,50 % versus 34,69 %, p < 0,02). No se encontraron diferencias en el riesgo de muerte tras el alta o discapacidad grave a los 2 años de EC con VC adecuada (OR: 0,79; IC95 %: 0,47-1,12) ni al considerarse el análisis por subcohortes. Conclusiones. Una VC adecuada se asoció con mejor crecimiento, pero no con menor riesgo de muerte tras el alta o discapacidad grave. La cohorte fortificada alcanzó mayor talla media a los 2 años de EC.

Objective. To determine the association between intrahospital growth rate (GR) and breast milk fortification and somatometry, and risk for death after discharge or severe disability at 2 years of corrected age (CA). Population and method. Retrospective analysis of GR and subsequent course. Infants born in the 1990-2015 period with a birth weight < 1500 g were included. Infants with diseases affecting growth were excluded. An overall cohort and 2 sub-cohorts were studied: infants born in the 1990-2001 period (without fortification) and 2002-2015 period (with fortification). The GR was estimated and deemed adequate if > 12 g/kg/day. Results. A total of 1194 patients were recruited. An adequate GR was associated with a higher median weight at 2 years of CA in the overall cohort (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0.02). The 2002-2015 cohort reached a higher mean height (86.42 ± 4.03 cm versus 85.56 ± 4.01, p = 0.02). More preterm infants caught-up growth at 2 years of CA in the overall cohort with an adequate GR (62.50 % versus 34.69 %, p < 0.02). No differences were observed in the risk for death after discharge or severe disability at 2 years of CA with an adequate GR (OR: 0.79; 95 % confidence interval: 0.47-1.12). Conclusions. An adequate GR was associated with improved growth, but not with a lower risk for death after discharge or severe disability. The cohort with fortified breast milk reached a higher mean height at 2 years of CA

Congenital Heart Disesase: A Retrospective Analysis from a Tertiary Referral Centre in Portugal

Abstract Background: Congenital heart disease is the leading cause of mortality among all congenital malformations. Objectives: To evaluate the incidence of congenital heart diseases in a central maternity hospital in Portugal from January 2003 to December 2018 and to determine survival in the first year of life. Methods: Retrospective analysis of newborns diagnosed with congenital heart diseases within 72 hours after birth. Malformations were divided according to pathophysiology. Cumulative survival analysis was performed by the Kaplan-Meier test. Stastical significance was set at p <0.05. Results: A total of 297 newborns with cardiac malformation was recorded among 47,198 live births (incidence of 6:1000), 16% associated with extra-cardiac disease. The most frequent congenital heart diseases were left-to-right shunt lesions (n = 216), followed by cyanotic (n = 41), acyanotic obstructive (n = 31) and miscellaneous (n = 9). Seventy (24%) patients had prenatal diagnosis, 88% of them cyanotic defects, and a positive association was found between prenatal diagnosis and mortality (p <0.001). Coarctation of the aorta was associated with gestational diabetes (p = 0.014). Atrial septal defect was more common in females (p = 0.02). Mortality rate due to heart disease was 3.4%. Patients with cyanotic disease, 99%, 97%, 97%, respectively, for patients with left-to-right shunt lesions, and 97%, 97%,97% for those with obstructive lesion cases. Conclusion: The incidence of congenital heart disease was 6:1000, mostly left-to-right shunt lesions. Heart disease accounted for only half of deaths, and cyanotic diseases have a high nonspecific mortality rate.

Intervención con probióticos para la prevención de enterocolitis necrotizante en prematuros extremos menores de 1500 gramos o de 32 semanas / Probiotic intervention to prevent necrotizing enterocolitis in extremely preterm infants born before 32 weeks of gestation or with a birth weight of less than 1500 g

Introducción. Existe evidencia del beneficio de los probióticos en prevenir enterocolitis necrotizante en prematuros extremos. Desde 2015, se usa probiótico preventivo en el Servicio de Neonatología, Hospital Hernán Henríquez Aravena, Temuco, Chile.Objetivo. Evaluar el impacto de este probiótico en la incidencia, gravedad, necesidad de terapia quirúrgica y letalidad por enterocolitis necrotizante en prematuros extremos. Pacientes y método. Estudio retrospectivo de cohortes. Datos analizados con Stata. Se aplicó la prueba exacta de Fisher para comparar porcentajes y, para los promedios, la prueba t para varianzas distintas. Los egresados entre 2015 y 2017 recibieron Lactobacillus reuteri Protectis (LRP), dosis única (1 x 108 unidades formadora de colonias) desde los primeros días de vida hasta cumplir las 36 semanas de edad gestacional corregida. Los controles egresados entre 2012 y 2014 no recibieron LRP.Resultados. El 3,45 % de los casos tuvo algún grado de enterocolitis: grado i (el 64 %), ii (el 18 %), iii (el 18 %); requirió cirugía el 18 % y no hubo letalidad. El 3,75 % de los controles históricos presentaron enterocolitis: grado i (el 12 %), ii (el 35 %), iii (el 53 %); el 64,7 % requirió cirugía, y el 47 % falleció. El grupo intervenido presentó grado ii o iii en un 36 %; en el grupo control, la sumatoria de estos estadios fue del 88 %.Conclusión.LRP administrado en dosis única diaria al prematuro extremo no modificó la incidencia de enterocolitis, pero disminuyó su gravedad, la letalidad y necesidad de tratamiento quirúrgico.

Introduction. There is evidence of the beneficial effects of probiotics to prevent necrotizing enterocolitis in extremely preterm infants. Probiotic prevention has been used since 2015 in the Division of Neonatology of Hospital Hernán Henríquez Aravena, Temuco, Chile.Objective. To assess the impact of this probiotic on the incidence, severity, surgical treatment requirement, and fatality rate of necrotizing enterocolitis in extremely preterm infants.Patients and methods. Retrospective, cohort study. Data were analyzed using Stata. Fisher's exact test was used to compare percentages, and the unequal variances t-test, for averages. Infants discharged between 2015 and 2017 received Lactobacillus reuteri Protectis (LRP), in a single dose (1 x 108 colony forming units), since the first days of life until 36 weeks of corrected gestational age. Controls discharged between 2012 and 2014 did not receive LRP.Results. Some degree of enterocolitis was observed in 3.45 % of cases: stage I (64 %), stage II (18 %), stage III (18 %); 18 % required surgery, and there were no deaths. Among historical controls, 3.75 % had enterocolitis: stage I (12 %), stage II (35 %), stage III (53 %); 64.7 % required surgery, and 47 % died. In the intervention group, stage II or III accounted for 36 % of cases, whereas in the control group, for 88 %.Conclusion. Administering a single daily dose of LRP to extremely preterm infants did not affect the incidence of enterocolitis, but reduced its severity, fatality rate, and surgical treatment requiremen

Producción de leche materna y estado emocional en madres de recién nacidos de muy bajo peso / Breast milk production and emotional state in mothers of very low birth weight infants

Introducción. Existe poca evidencia de la influencia de variables emocionales en la lactancia de madres de recién nacidos de muy bajo peso al nacer (RNMBPN). El objetivo de este estudio fue medir la producción de leche materna (PLM) en dos momentos de la internación neonatal y su asociación con los niveles de ansiedad, depresión y autoeficacia en lactancia en madres de RNMBPN.Población y métodos. Estudio prospectivo, observacional, multicéntrico en madres de RNMBPN (500-1500 g), en 9 centros de la Red NEOCOSUR. La PLM se obtuvo midiendo lo extraído por cada madre. Se utilizaron las escalas STAI para ansiedad, BDI para depresión, y, la escala piloto ALMA para autoeficacia. Estas fueron aplicadas a los 14 días de vida y a las 36 semanas posmenstruales. Se registraron, además, las características biosociales de madres y neonatos. Resultados. Participaron 118 madres. La PLM media a los 14 días fue de 169 ml (desvío estándar ­DE­ ± 132,4) y de 285 ml (DE ± 266,9) a las 36 semanas, y se asoció significativamente con percepción de autoeficacia en lactancia (p < 0,001), que se mantuvo durante la hospitalización. Existió una tendencia a menor producción en madres con mayores índices de depresión a los 14 días de vida de su hijo, pero no a las 36 semanas. No se encontró asociación entre PLM y ansiedad. No se encontraron asociaciones consistentemente significativas con variables biosociales. Conclusión. La PLM se asoció positivamente con autoeficacia en lactancia; no se encontró asociación con ansiedad y depresión en madres de RNMBPN

Introduction. There is little evidence regarding the influence of emotional variables on breastfeeding among mothers of very low birth weight infants (VLBWIs). The objective of this study was to measure breast milk production (BMP) at two points in time during neonatal hospitalization and its association with anxiety, depression, and breastfeeding self-efficacy levels among mothers of VLBWIs.Population and methods. Prospective, observational, and multicenter study in mothers of VLBWIs (500-1500 g) from 9 NEOCOSUR Network centers. BMP was obtained by measuring the amount extracted by each mother. The STAI scale was used for anxiety, the BDI scale for depression, and the ALMA pilot scale for self-efficacy. They were administered at 14 days of life and at 36 weeks of postmenstrual age. The biosocial characteristics of mothers and neonates were also recorded.Results. A total of 118 mothers participated. Mean BMP was 169 mL (standard deviation [SD]: ± 132.4) at 14 days and 285 mL (SD: ± 266.9) at 36 weeks, and it was significantly associated with the perception of breastfeeding self-efficacy (p < 0.001), which was maintained during hospitalization. There was a lower production trend among mothers with higher depression indices at 14 days of life, but not at 36 weeks. No association was observed between BMP and anxiety. No consistently significant associations were observed with biosocial variables.Conclusion. BMP was positively associated with breastfeeding self-efficacy; no association was observed with anxiety and depression among mothers of VLBWIs

Displasia del desarrollo de la cadera: tamizaje y manejo en el lactante / Developmental dysplasia of the hip: screening and management in the infant

La displasia del desarrollo de la cadera comprende un conjunto de anormalidades que afectan la articulación coxofemoral: la displasia, subluxación y luxación de la cadera. El concepto de "displasia" describe anormalidades en la estructura femoral, acetabular o ambas. Corresponde a la patología ortopédica más frecuente del recién nacido y lactante, lo que genera mucha preocupación e intranquilidad entre los padres, en los primeros controles sanos de sus hijos. Es una patología en la que un diagnóstico oportuno y precoz son la clave para poder realizar un tratamiento efectivo, obteniendo como resultado una cadera clínica y radiológicamente normal al finalizar el desarrollo esquelético. Para esto es fundamental conocer la patología e ir activamente en su búsqueda. Actualmente existe mucha discusión sobre la manera de pesquisar esta patología. En Chile, se realiza tamizaje universal con imagen -radiografía de pelvis- a todos los niños a los 3 meses de edad. El objetivo de la siguiente revisión, es traer a la práctica clínica actual de todos aquellos profesionales que se enfrentan en distintos escenarios a esta patología: médicos de atención primaria, enfermeras, médicos en etapas de destinación y formación en distintas regiones del país, pediatras y ortopedistas, aquellas características y signos de sospecha propios de esta enfermedad y detallar las herramientas para un correcto diagnóstico y oportuno tratamiento.

Developmental dysplasia of the hip (DDH) comprises a set of abnormalities that affect the hip joint: hip dysplasia, subluxation, and dislocation. It is the most frequent orthopedic pathology of the newborn and infant, and it generates great concern among parents during the first health check-ups of their children. It is a condition in which a timely and early diagnosis is key to be able to carry out an effective treatment, obtaining as a result of a clinically and radiologically normal hip at the end of skeletal development. For this, it is essential to know this orthopedic condition and actively search for it. Currently, there is much discussion about how to screen DDH. In Chile, universal screening with imaging - pelvic radiography - is performed on all children at 3 months of age. The objective of the following review is to bring to the current clinical practice of all those professionals who face this pathology in different scenarios: primary care physicians, nurses, physicians in training stages in different regions of the country, pediatricians and orthopedic surgeons, signs of suspicion typical of the disease and detail the assessment tools for a correct diagnosis and timely treatment.
