Predicting attachment in Portuguese infants born very or extremely preterm: Understanding the roles of infant regulatory behavior, maternal sensitivity, and risk factors.

A growing body of research shows that early attachment relationships are foundational for children's later developmental and psychosocial outcomes. However, findings are mixed regarding whether preterm birth predicts later attachment, but insecurity is generally more prevalent among infants at higher medical and/or social/familial risk. This longitudinal study aimed to identify specific relational, familial/demographic, and perinatal predictors of attachment in a sample of 63 Portuguese infants born very or extremely preterm (VEPT, <32 gestational weeks) and their mothers from diverse socioeconomic backgrounds. One-third of the mothers had social/family risk factors (e.g., single parent, immigrant, unemployed, low education, and/or low income). At 3 months (corrected age), dyads were observed during social interaction in the Face-to-Face Still-Face paradigm (FFSF) and during free play. At 12 months, mother-infant dyads were observed in Ainsworth's Strange Situation. Over half (58.7%) of the infants were classified as insecurely attached. Social-Positive Oriented regulatory behavior pattern, higher maternal sensitivity, higher infant cooperation during free play, number of siblings and an absence of social/family risk factors were associated with attachment security. Perinatal variables were unrelated to attachment. Findings indicate that both relational and social contextual factors contribute to attachment in this biologically vulnerable sample.

Un creciente cuerpo investigativo muestra que las relaciones afectivas tempranas son fundamentales para posteriores resultados de desarrollo y sicosociales de los niños. Sin embargo, los resultados son variados acerca de si el nacimiento prematuro predice la afectividad posterior, pero la inseguridad es generalmente más prevalente entre infantes bajo más alto riesgo médico y/o social/familiar. Este estudio longitudinal se propuso identificar factores específicos de predicción de la afectividad, relacionales, familiar/demográficos y perinatales en un grupo muestra de 63 infantes portugueses nacidos muy o extremadamente prematuros (VEPT, < 32 semanas gestacionales) y sus madres de diversos niveles socioeconómicos. Un tercio de las madres tenían factores de riesgo social/familiar (v.g. madre soltera, inmigrante, desempleada, de baja educación y/o de bajos recursos económicos). A los tres meses (edad corregida), se les observó a las díadas durante la interacción social en el paradigma de Cara a Cara y Rostro Inmutable (FFSF) y durante el juego libre. A los 12 meses, se les observó a las díadas madre-infante por medio de la Situación Extraña de Ainsworth. Se clasificó más de la mitad (58.7%) de los infantes como afectivamente inseguros. Entre los factores de predicción de la afectividad segura se incluyó un patrón de conducta regulatoria con orientación social positiva durante FFSF, una sensibilidad materna más alta y la cooperación del infante durante el juego libre, así como la ausencia de factores de riesgo sociales/familiares. Las variables perinatales no estuvieron relacionadas con la afectividad. Los resultados indican que los factores contextuales, tanto relacionales como sociales contribuyen a la afectividad en este grupo biológicamente vulnerable.

Preterm infant mental health in the neonatal intensive care unit: A review of research on NICU parent-infant interactions and maternal sensitivity.

Caregiving relationships in the postnatal period are critical to an infant's development. Preterm infants and their parents face unique challenges in this regard, with infants experiencing separation from parents, uncomfortable procedures, and increased biologic vulnerability, and parents facing difficulties assuming caregiver roles and increased risk for psychological distress. To better understand the NICU parent-infant relationship, we conducted a review of the literature and identified 52 studies comparing observed maternal, infant, and dyadic interaction behavior in preterm dyads with full-term dyads. Eighteen of 40 studies on maternal behavior found less favorable behavior, including decreased sensitivity and more intrusiveness in mothers of preterm infants, seven studies found the opposite, four studies found mixed results, and 11 studies found no differences. Seventeen of 25 studies on infant behavior found less responsiveness in preterm infants, two studies found the opposite, and the remainder found no difference. Eighteen out of 14 studies on dyad-specific behavior reported less synchrony in preterm dyads and the remainder found no differences. We identify confounding factors that may explain variations in results, present an approach to interpret existing data by framing differences in maternal behavior as potentially adaptive in the context of prematurity, and suggest future areas for exploration.

Las relaciones de prestación de cuidados en el período postnatal son críticas para el desarrollo del infante. Los infantes nacidos prematuramente y sus progenitores enfrentan retos únicos a este respecto, con los infantes que experimentan la separación de sus progenitores, procedimientos incómodos, así como un aumento en la vulnerabilidad biológica; y los progenitores enfrentando dificultades al asumir el papel de cuidadores y el aumento de riesgo de angustia sicológica. Para comprender mejor la relación progenitor-infante en la Unidad Neonatal de Cuidados Intensivos (NICU), llevamos a cabo una revisión de la literatura e identificamos 52 estudios que comparan la observada conducta de interacción materna, del infante y de la díada en díadas de infantes prematuros con díadas de infantes de gestación completa. Dieciocho de 40 estudios sobre la conducta materna encontraron una menos favorable conducta, incluyendo una baja en la sensibilidad y más intrusión en el caso de madres de infantes prematuros; 7 estudios encontraron que se daba la situación opuesta; 4 estudios presentaron resultados mixtos; y 11 estudios no encontraron diferencias. Diecisiete de 25 estudios sobre el comportamiento del infante encontraron una menor capacidad de respuesta en infantes prematuros; dos estudios encontraron que se daba la situación opuesta; y el resto de los estudios no encontró ninguna diferencia. Ocho de 14 estudios sobre el comportamiento específico de la díada reportaron menos sincronía en las díadas con infantes prematuros y el resto de los estudios no encontró ninguna diferencia. Identificamos factores confusos que pudieran explicar las variaciones en los resultados, presentamos un acercamiento para interpretar la información existente por medio de enmarcar las diferencias en la conducta materna como potencialmente adaptable en el contexto del nacimiento prematuro, y sugerimos futuras áreas para ser exploradas.

Les relations de soin dans la période postnatale sont critiques pour le développement du nourrisson. Les bébés nés avant terme et leurs parents font face à des défis uniques à cet égard, avec les bébés faisant l'expérience de la séparation des parents, des procédures désagréables et difficiles, et une vulnérabilité biologique accrue, et les parents faisant face aux difficultés assumant des rôles de soignants et étant à risque plus élevé de détresse psychologique. Afin de comprendre la relation parent-nourrisson USIN nous avons passé en revue toutes les recherches et identifié 52 études comparant le comportement d'interaction dyadique, maternel et du nourrisson chez des dyades prématurées avec des dyades à plein terme. 18 des 40 études sur le comportement maternel ont trouvé un comportement moins que favorable, y compris une sensibilité décrue et plus d'intrusion chez les mères de nourrissons prématurés, 7 études ont trouvé le contraire, 4 études ont trouvé des résultats mélangés, et 11 études n'ont trouvé aucune différence. 17 études sur 25 sur le comportement du nourrisson ont trouvé une réaction moindre chez les nourrissons prématurés deux études ont trouvé le contraire, et le reste n'a trouvé aucune différence. 8 études sur 14 sur le comportement spécifique à la dyade ont fait état de moins de synchronie chez les dyades avant terme et les autres études n'ont trouvé aucune différence. Nous identifions des facteurs confondants qui pourraient expliquer des variations dans les résultats et nous présentons une approche pour interpréter les données existantes en cadrant des différences dans le comportement maternel comme étant potentiellement adaptatives dans le contexte de la prématurité et nous suggérons des domaines futurs d'exploration.

Multimodal assessments of preterm temperament across the first year of life: Continuity, stability, and moderation by country of origin and infant age.

There is limited research regarding the continuity, stability, and role of country of origin in preterm infant temperament across the first year of life. This prospective longitudinal study examined patterns of mean-level continuity and individual-differences stability of select scales of temperament at 6 and 12 months in preterm infants from three countries, Chile (n = 47), United Kingdom (n = 44), and United States (n = 50). Temperament was assessed with the Infant Behavior Questionnaire and observed using the Bayley Behavior Rating Scale. Continuity and stability across infant age, country effects, and interactions of country and age on preterm infant temperament were examined. Chilean mothers rated infants higher in soothability, duration of orienting, and orientation/engagement compared with mothers from the United Kingdom and/or United States. Continuity of temperament from 6 to 12 months varied by country: Chilean mothers reported increasing smiling and laughter and activity level from 6 to 12 months, and mothers from the United Kingdom reported decreasing smiling and laughter and increasing fear from 6 to 12 months. Infant temperament was stable in all three countries. Correlations evidenced low concordance between maternal reports and examiner observations of infant temperament at 12 months. However, among Chilean infants, higher maternal reported activity level was associated with higher examiner observed orientation/engagement score.

Hay una limitada investigación acerca de la continuidad, la estabilidad y el papel del país de origen en el temperamento de infantes nacidos prematuramente a lo largo del primer año de vida. Este potencial estudio longitudinal examinó patrones de continuidad en el promedio de nivel y las diferencias individuales en cuanto a la estabilidad de selectas escalas de temperamento a los 6 y 12 meses en infantes prematuros de tres países, Chile (n = 47), Reino Unido (n = 44) y Estados Unidos (n = 50). El temperamento se evaluó con el Cuestionario de Comportamiento del Infante y el mismo se observó usando la Escala de Puntuación del Comportamiento de Bayley. Se examinaron la continuidad y la estabilidad a lo largo de la edad del infante, los efectos del país, así como las interacciones entre país y edad en el temperamento de los infantes prematuros. Las madres chilenas evaluaron a sus infantes con más altos puntajes en cuanto a posibilidad de tranquilizarlos, duración de orientarlos y la orientación/participación en comparación con madres del Reino Unidos y/o de Estados Unidos. La continuidad de temperamento de los 6 a 12 meses varió según el país: las madres chilenas reportaron aumento en la sonrisa y la risa, y el nivel de actividad de los 6 a 12 meses, y las madres del Reino Unido reportaron una disminución en la sonrisa y la risa, y un aumento en el temor de los 6 a 12 meses. El temperamento del infante fue estable en los tres países. Las correlaciones son evidencia de la concordancia entre los reportes maternos y las observaciones del examinador del temperamento del infante a los 12 meses. Sin embrago, entre los infantes chilenos, el más alto nivel de actividad reportado por las madres se asoció con un más alto puntaje del examinador en cuanto a la observada orientación/participación.

Nous n'avons que des recherches limitées sur la continuité, la stabilité et le rôle du pays d'origine dans le tempérament du bébé prématuré au fil de la première année de la vie. Cette étude longitudinale prospective a examiné les modèles de continuité au niveau moyen et la stabilité des différences individuelles de certaines échelles de tempérament à 6 et à 12 mois chez les enfants prématurés de trois pays, le Chili (n = 47), le Royaume Uni (n = 44) et les Etats-Unis d'Amérique (n = 50). Le tempérament a été évalué au moyen du Questionnaire du Comportement du Nourrisson et observé en utilisant l'Echelle de Bailey d'Evaluation du Comportement du Nourrisson. La continuité et la stabilité au travers de l'âge du nourrisson, les effets du pays et les interactions du pays et de l'âge sur le tempérament du bébé prématuré ont été examinés. Les mères chiliennes ont évalué leurs bébés plus haut pour ce qui concernait la capacité à être calmé, la durée de l'orientation et l'orientation/l'engagement par comparaison aux mères du Royaume Uni et/ou des Etats-Unis. La continuité du tempérament de 6 à 12 mois a varié par pays: les mères chiliennes ont fait état de plus de sourires et de rires et d'un niveau d'activité plus élevé de 6 à 12 mois et les mères du Royaume Uni ont fait état d'une décroissance des sourires et des rires et d'une plus grande peur de 6 à 12 mois. Le tempérament du nourrisson était stable dans les trois pays. Les corrélations ont montré une concordance faible entre les rapports maternels et les observations de l'examinateur du tempérament du nourrisson à 12 mois. Cependant, chez les enfants chiliens, un niveau d'activité plus élevé rapporté par la mère était lié à un score d'orientation/d'engagement observé plus élevé de la part de l'examinateur.

Adaptation of infant mental health services to preterm infants and their families receiving neonatal intensive care unit services during the COVID-19 pandemic.

Multiple changes and stressors at the family, hospital, and societal levels have resulted from the COVID-19 pandemic that impact the early social environment of infants in Neonatal Intensive Care Unit (NICU) settings. This manuscript reviews these pandemic-related adversities, including hospital-wide visitor restrictions, mask requirements that interfere with caregiver facial expressions, parental anxiety about virus transmission, and reduced support services. We will further describe adaptations to mental health service delivery and approaches to care in the NICU to mitigate increased risk associated with pandemic-related adversities. Adaptations include integration of technology, staff education and support, and delivery of activity kits to encourage parent-infant bonding. Data was collected as part of routine program evaluation of infant mental health services from one 50-bed NICU setting and describes family concerns, barriers to visitation, and utilization of mental health services during the pandemic. Concerns related to COVID-19 rarely emerged as the primary presenting issue by the families referred for infant mental health services from April through December of 2020. However, a number of families indicated that infection concerns and visitation restrictions posed significant challenges to their parenting and/or coping. There were significant discrepancies noted between the visitation patterns of families with public and private insurance. Several adaptations were developed in response to the multiple challenges and threats to infant mental health present during the COVID-19 pandemic.

Múltiples factores de estrés a nivel de la familia, el hospital y la sociedad han resultado de la pandemia del COVID-19, los cuales han tenido un impacto en el temprano ambiente social de los infantes en el ambiente de la Unidad de Cuidados Intensivos Neonatales (NICU). Este artículo revisa estas situaciones adversas relacionadas con la pandemia, incluyendo las restricciones generales de visita al hospital, el requisito de llevar máscara que interfiere con las expresiones faciales de quien presta el cuidado, la ansiedad de los padres acerca de la transmisión del virus y los reducidos servicios de apoyo. Describimos además adaptaciones al ofrecimiento de servicios de salud mental en NICU para mitigar el aumento del riesgo asociado con las situaciones adversas relacionadas con la pandemia. Estas adaptaciones incluyen la integración de tecnología, la educación y el apoyo del personal, así como el ofrecimiento de material para actividades que promueven la unión afectiva entre progenitor e infante. Se recogió información como parte de la evaluación rutinaria del programa sobre los servicios sicosociales en el caso de una unidad NICU de 50 camas y se describen las preocupaciones de la familia, los obstáculos a la visita, así como la utilización de los servicios de salud mental infantil durante la pandemia. El COVID-19 raramente surgió como el principal asunto que enfrentaban las familias que fueron referidas para intervención de abril a diciembre de 2020. Sin embargo, algunas familias indicaron que las preocupaciones de adquirir una infección y las restricciones de visita presentaron retos significativos a la crianza y/o a la manera de arreglárselas. Se notaron discrepancias significativas entre los patrones de visita de familias con seguro público o con seguro privado. Como respuestas a estas amenazas a la salud mental infantil presentes durante la pandemia del COVID-19, se desarrollaron varias adaptaciones.

Des facteurs de stress multiples aux niveaux de la famille, de l'hôpital et de la société ont résulté de la pandémie du COVID-19 qui impacte l'environnement social précoce des nourrissons dans les Unités Néonatales de Soins Intensifs (UNSI). Cet article passe en revue ces adversités liées à la pandémie, y compris les restrictions pour les visiteurs dans les hôpitaux, les obligations de porter le masque qui interfèrent avec les expressions faciales de la personne prenant soin du bébé, l'anxiété parentale à propos de la transmission du virus et des services de soutien réduits. Nous décrivons des adaptations à la prestation de service de santé mentale dans l'UNSI afin de mitiger le risque accru associé aux adversités liées à la pandémie. Des adaptations ont inclus l'intégration de la technologie, la formation et le soutien aux employés, la livraison de kits d'activités afin d'encourager le lien parent-bébé. Des données ont été recueillies comme faisant partie de l'évaluation de routine de services psychosociaux dans le contexte d'une INSI de 50 lits et décrivent les inquiétudes familiales, les barrières aux visites, l'utilisation de services de santé mentale du nourrisson durant la pandémie. Le COVID-19 a rarement émergé comme étant le problème principal présenté par les familles ayant reçu une intervention d'avril à décembre 2020. Cependant certaines familles ont indiqué que les inquiétudes touchant à l'infection et les restrictions des visites ont posé des défis importants à leur parentage et/ou à leur adaptation. Des différences importantes ont été notées entre les patterns de visites des familles ayant une assurance publique et une assurance privée. Plusieurs adaptations ont été développées pour faire face aux dangers pour la santé mentale infantile présents durant la pandémie de COVID-19.

The association of infant temperament and maternal sensitivity in preterm and full-term infants.

Infants who experience sensitive caregiving are at lower risk for numerous adverse outcomes. This is especially true for infants born preterm, leading them to be more susceptible to risks associated with poorer quality caregiving. Some research suggests that preterm and full-term infants differ on temperament, which may contribute to these findings. This study aimed to investigate associations between infant temperament (negative emotionality, positive affectivity/surgency, and orienting/regulatory capacity) and maternal sensitivity among infants born preterm (M = 30.2 weeks) and full term. It was hypothesized that mothers of infants born preterm and mothers of infants with more difficult temperaments would display lower sensitivity, indicated by lower responsiveness to nondistress, lower positive regard, and higher intrusiveness. Videotaped play interactions and a measure of temperament (Infant Behavior Questionnaire) were coded for 18 preterm and 44 full-term infants at 9 months (corrected) age. Results suggest that mothers of preterm and full-term infants differed significantly in responding to their infants, but these results cannot be explained by infant temperament. Preterm status and sociodemographic risk emerged as correlates of maternal behavior, such that mothers of infants born preterm and mothers with greater sociodemographic risk displayed lower levels of maternal sensitivity.

Los infantes que experimentan un cuidado sensible se encuentran bajo un riesgo más bajo en cuanto a numerosos resultados adversos. Esto es especialmente cierto para infantes nacidos prematuramente, lo cual conlleva que ellos sean más susceptibles a los riesgos asociados con una más pobre calidad de cuidado. Alguna investigación sugiere que los infantes prematuros y aquellos de completa gestación difieren en el temperamento, lo cual pudiera contribuir a estos resultados. Este estudio se propuso investigar las asociaciones entre el temperamento del infante (sentido negativo de la emoción, afectividad/resurgencia positiva y capacidad de orientación/regulatoria) y la sensibilidad materna entre infantes nacidos prematuramente (M = 30.2 semanas) y los nacidos dentro de la gestación completa. La hipótesis fue que las madres de infantes nacidos prematuramente y las madres de infantes con temperamentos más difíciles mostrarían una más baja sensibilidad, indicado por una más baja reacción sensible a la falta de angustia, más baja consideración positiva y más alta intrusión. Se codificaron las interacciones de juego grabadas en video y una medida de temperamento (Cuestionario de Conducta del Infante) para 18 prematuros y 44 infantes de gestación completa a los nueves meses (corregidos) de edad. Los resultados sugieren que las madres de infantes prematuros y de gestación completa difirieron significativamente al responder a sus infantes, pero estos resultados no pueden ser explicados con base en el temperamento del infante. La condición de prematuro y el riesgo sociodemográfico surgieron como una correlación del comportamiento materno, al punto que las madres de infantes nacidos prematuramente y las madres con mayores riesgos sociodemográficos mostraron niveles más bajos de sensibilidad materna.

Les nourrissons qui font l'expérience de soins sensibles sont à moindre risque pour bien des résultats adverses. Cela est particulièrement vrai des nourrissons nés prématurés, ce qui les amène à être plus susceptibles aux risques liés à une plus mauvaise qualité de soins de la personne qui prend soin d'eux. Certaines recherches suggèrent que les nourrissons prématurés et les nourrissons à terme diffèrent quant au tempérament, ce qui peut contribuer à ces résultats. Cette étude s'est donné pour but de rechercher les liens entre le tempérament du nourrisson (émotionalité négative, affectivité/dynamisme positif, et capacité d'orientation/régulatoire) et la sensibilité maternelle chez les nourrissons nés prématurés (M = 30,2 semaines) et ceux à plein terme. Nous avons pris pour hypothèse que les mères des nourrissons nés prématurés et les mères de nourrissons ayant des tempéraments plus difficiles feraient preuve d'une sensibilité plus basse, indiquée par une réaction moindre à la non-détresse, un égard positif plus bas et une intrusion plus élevée. Des interactions de jeu filmées et une mesure de tempérament (Questionnaire du Comportement du Nourrisson) ont été codées pour 18 prématurés et 44 nourrissons à termes à neuf mois (âge corrigé). Les résultats suggèrent que les mères de prématurés et de nourrissons à terme ont différé de manière importante dans leur réaction à leurs nourrissons, mais ces résultats ne peuvent pas être expliqués par le tempérament du nourrisson. Le statut de prématuré et le risque sociodémographique ont émergé comme corrélat du comportement maternel, de telle manière que les nourrissons nés prématurés et les mères avec un risque sociodémographique plus élevé ont fait état de niveaux plus bas de sensibilité maternelle.

NICU music therapy effects on maternal mental health and preterm infant's emotional arousal.

In recent decades, music therapy in the Neonatal Intensive Care Unit (NICU) has been shown to regulate preterm infant's physiological responses and improve maternal mental health. This study investigated the effects of the music therapy intervention for the mother-preterm infant dyad (MUSIP) for maternal anxiety, postnatal depression, and stress, and preterm infants' weight gain, length of hospitalization, heart rate (HR), and oxygen saturation (So2 ). A pre-experimental design was used with 33 mother-preterm infant dyads in a Brazilian NICU: 16 dyads in the Music Therapy Group (MTG) and 17 dyads in the Control Group (CG). The MTG took part in the MUSIP, aimed at supporting maternal singing with the preterm baby. Infants' HR and So2 were recorded at each minute from 10 min before to 10 min after sessions 1, 3, and 6. Before infants' discharge, maternal anxiety and depression scores were lower in the MTG compared to the CG. Anxiety, depression, and stress levels decreased significantly after the intervention in the MTG. With regard to infants, HR and So2 ranges were higher during music therapy, compared to before and after sessions. MUSIP improved maternal mental health and affected preterm infants' emotional arousal, with positive trends in decreasing HR, stabilizing So2 , and reducing length of hospitalization.

En décadas recientes, la terapia musical de la Unidad de Cuidados Intensivos Neonatales ha demostrado poder regular las respuestas fisiológicas del infante nacido prematuramente y mejorar la salud mental materna. Este estudio investigó los efectos de la Intervención de Terapia Musical para la Díada Madre-Infante Prematuro (MUSIP) en cuanto a la ansiedad materna, la depresión posnatal y el estrés, así como el aumento del peso de los infantes prematuros, el tiempo de hospitalización, el ritmo cardíaco (HR) y la saturación de oxígeno (SO2). Un diseño preexperimental se usó con 33 díadas de madre-infante prematuro en una Unidad brasileña de Cuidados Intensivos Neonatales: 16 díadas en el Grupo de Terapia Musical (MTG) y 17 díadas en el Grupo de Control (CG). El MTG participó en MUSIP, con la finalidad de apoyar el canto materno con el bebé prematuro. Se anotó el HR y SO2 de los infantes en cada minuto a partir de 10 minutos antes hasta 10 minutos después de la Sesión 1, 3 y 6. Antes de darles de alta a los infantes, se redujeron los puntajes de ansiedad y depresión maternas en el MTG tal como se le comparó con el CG. Los niveles de ansiedad, depresión y estrés se redujeron significativamente después de la intervención en el MTG. Con respecto a los infantes, los intervalos de HR y SO2 fueron más altos durante la terapia musical, tal como se les comparó con los momentos antes y después de las sesiones. MUSIP ayudó a mejorar la salud mental materna y afectó el despertar emocional de los infantes prematuros, con tendencias a reducir el HR, estabilizar el SO2 y reducir el tiempo de hospitalización.

Dans les vingt et trente dernières années, il a été démontré que la thérapie musicale en Réanimation Néonatale régule les réponses physiologiques du bébé prématuré et améliore la santé mentale maternelle. Cette étude a étudié les effets de l'Intervention de Thérapie Musicalepour la dyade Mère-Bébé Prématurés (MUSIP) pour l'anxiété maternelle, la dépression postnatale, et le stress, ainsi que la prise de poids des bébés prématurés, la longueur de l'hospitalisation, le rythme cardiaque (RC ici) et la saturation d'oxygène (sO2). Une structure pré-expérimentale a été utilisée avec 33 dyades mère-nourrisson prématuré dans une Réanimation Néonatale au Brésil: 16 dyades dans le Groupe Thérapie Musicale (GTM en français) et 17 dyades dans le Groupe de Contrôle (GC en français). Le groupe GTM a pris part à la MUSIP, destiné à aider et soutenir les mères à chanter avec leur bébé prématuré. Le RC et la sO2 des nourrissons ont été enregistrés à chaque minute pendant 10 minutes avant jusqu'à 10 minutes après la Session 1, 3, et 6. Les scores d'évacuation des nourrissons, de l'anxiété maternelle et de dépression maternelle étaient moins élevés dans le GTM que dans le GC. L'anxiété, la dépression et les niveaux de stress ont baissé de manière importante durant l'intervention dans le groupe GTM. Pour ce qui concerne les nourrissons, les éventails de RC et de sO2 était plus élevés durant la thérapie musicale, comparés à avant et après les sessions. La MUSIP a amélioré la santé mentale maternelle et affecté la stimulation émotionnelle des nourrissons prématurés, avec des tendances positives dans la baisse du RC, la stabilisation sO2 et la réduction de la longueur de l'hospitalisation.

Longitudinal changes in attachment patterns of preterm infants born in a non-Western country.

Unexpected early birth of an infant may affect the attachment formation of mother-child dyads. This longitudinal study aimed to explore mother-infant attachment patterns of very preterm (VPT) and preterm (PT) infants compared to their term-born peers in a non-Western country. Neurodevelopmental outcomes of infants, maternal anxiety and depressive symptoms, and sociodemographic features were evaluated to explore their effects on attachment. Eighteen VPT, 11 PT, 11 term infants and their mothers participated. Observations of attachment patterns and neurodevelopmental assessments were performed at 18 and 24 months of corrected age. This study identified a change in attachment patterns of VPT infants over time such that VPT infants tended to have less insecure attachment patterns with their mothers at the end of the infancy period. While motor and language development scores were associated with attachment patterns at 18 months, models predicting attachment patterns were no longer significant at 24 months. Therefore, change in VPT infants' developmental outcomes and attachment patterns over time suggests that preterm birth itself is not necessarily a risk factor for developing insecure attachment patterns; yet, developmental delays may account for insecure attachment patterns. It is suggested that efforts to promote developmental outcomes of preterm infants may improve mother-child attachment.

El inesperado nacimiento prematuro de un infante pudiera afectar la formación de la afectividad de las díadas madre-niño. Este estudio longitudinal se propuso explorar los patrones de afectividad madre-infante de infantes nacidos muy prematuramente (VPT) e infantes prematuros (PT) comparados con sus compañeros nacidos dentro del término regular en un país no occidental. Se evaluaron los resultados de desarrollo neurológico de los infantes, la ansiedad y síntomas depresivos maternos, así como las características socio-demográficas, con el fin de explorar sus efectos sobre la afectividad. Dieciocho VPT 11 PT, 11 infantes nacidos dentro del término regular y sus madres participaron. Las observaciones de patrones de afectividad y evaluaciones de desarrollo neurológico se llevaron a cabo a los 18 y 24 meses de la edad corregida. Este estudio identificó un cambio en los patrones de afectividad de los infantes VPT a lo largo del tiempo, de tal manera que los infantes VPT tendieron a tener menos patrones de afectividad insegura con sus madres al final del período de infancia. Mientras que los puntajes de desarrollo motor y de lenguaje se asociaron con patrones de afectividad a los 18 meses, los modelos que predijeron los patrones de afectividad ya no eran significativos a los 24 meses. Por tanto, el cambio en los resultados de desarrollo de los infantes VPT y los patrones de afectividad a lo largo del tiempo sugieren que el nacimiento prematuro en sí no es necesariamente un factor de riesgo para desarrollar patrones de afectividad insegura, pero los retardos en el desarrollo pudieran ser responsables de patrones de afectividad insegura. Se sugiere que los esfuerzos para promover los resultados de desarrollo de infantes prematuros pudieran mejorar la afectividad madre-niño.

Mind-mindedness and parenting stress in mothers of preterm and full-term infants: The moderating role of perceived social support.

The goal of this study was to examine the effects of preterm birth and maternal childbirth-related posttraumatic stress and parenting stress on maternal mind-mindedness (MM). The study also investigated the effects of perceived social support on parenting stress and MM. Sixty-five preterm (N = 32) and full-term (N = 33) mother-infant dyads were observed at 6 months. Measures of maternal MM were obtained from observations of mother-infant interaction. Mothers also provided ratings of their posttraumatic stress disorder (PTSD) symptoms, parenting stress, and perceived social support via an online survey. Experiencing a preterm birth did not affect mothers' use of mental state descriptors during mother-infant interaction. Neither childbirth-related posttraumatic stress nor parenting stress directly affected maternal ability to comment on the child's mental states appropriately. However, at medium and high levels of perceived social support, a negative association between parenting stress and MM was observed. Maternal perception of being emotionally supported by significant others promoted MM in mothers showing low or mild levels of parenting stress, but not in mothers experiencing high stress in parenting their infants. Results suggest that a proclivity to MM might be affected by the interaction between parenting stress and social support, rather than by childbirth-related variables, such as prematurity.

El propósito de este estudio fue examinar los efectos del nacimiento prematuro y el estrés materno postraumático relacionado con dar a luz, y el estrés de la crianza sobre la disposición de la mente (MM). El estudio también investigó los efectos que la percepción del apoyo social tiene en el estrés de la crianza y la disposición de la mente. Se observaron 65 díadas de madre-infantes prematuros (N = 32) y de gestación completa (N = 33) a los 6 meses. Las medidas de la disposición mental materna se obtuvieron de observaciones de la interacción madre-infante. Las madres también suministraron los puntajes de sus síntomas de PTSD, el estrés de la crianza y la percepción del apoyo social por medio de una encuesta electrónica. El experimentar un nacimiento prematuro no afectó el uso por parte de las madres de los factores de descripción del estado mental durante la interacción madre-infante. Ni el estrés postraumático relacionado con el dar a luz ni el estrés de la crianza directamente afectaron la habilidad materna para comentar de manera apropiada sobre los estados mentales del niño. Sin embargo, al nivel medio y alto de la percepción de apoyo social, se observó una asociación negativa entre el estrés de crianza y la disposición de la mente. La percepción materna de contar con el apoyo emocional de su pareja promovió la disposición mental de las madres que mostraban bajos o leves niveles de estrés de crianza, aunque no así en aquellas madres que experimentaban un nivel alto de estrés en la crianza de sus infantes. Los resultados sugieren que una propensión a la disposición mental pudiera ser afectada por la interacción entre el estrés de crianza y el apoyo social, en vez de las variables relacionadas con el dar a luz, tal como el nacimiento prematuro.

Le but de cette étude était d'examiner les effets du stress posttraumatique lié à la naissance avant terme et à l'accouchement maternel et le stress de parentage sur l'Etat d'esprit/Orientation mentale (abrégé ici EE/OM). L'étude s'est aussi penchée sur les effets du soutien social perçu du stress de parentage et de l'EE/OM maternel. Soixante-cinq dyades mères-bébés nés avant terme (N = 32) et à plein terme (N = 33) ont été observées à 6 mois. Les mesures d'EE/FM maternel ont été obtenues d'observations de l'interaction mère-bébé. Les mères ont aussi offert des évaluations de leurs propres symptômes ESPT, du stress de parentage, et du soutien social perçu au travers d'un questionnaire en ligne. Le fait d'avoir fait l'expérience d'une naissance avant terme n'a pas affecté l'utilisation de descripteurs de santé mentale des mères durant l'interaction mère-bébé. Ni le stress posttraumatique lié à l'accouchement ni le stress de parentage n'ont affecté directement la capacité maternelle à commenter les états mentaux de l'enfant de manière appropriée. Cependant, à des niveaux moyens et élevés de soutien social perçu, une association négative entre le stress de parentage et l'EE/OM a été observée. La perception maternelle d'être soutenue émotionnellement par leurs partenaires a promu l'EE/FM chez les mères faisant preuve de niveaux bas ou peu élevés de stress de parentage, mais pas chez les mères faisant preuve de stress élevé dans le parentage de leurs bébés. Les résultats suggèrent qu'une tendance à l'EE/OM peut être affectée par l'interaction entre le stress de parentage et le soutien social, plutôt que par des variables liées à l'accouchement, comme la prématurité.

Baixo peso ao nascer, prematuridade e restrição de crescimento intra-uterino: resultados dos dados de base da primeira coorte de nascimentos indígenas no Brasil (coorte de nascimentos Guarani).

ABSTRATO: FUNDO: O baixo peso ao nascer (BPN) continua sendo um importante problema de saúde global, associado a uma série de resultados adversos de saúde ao longo da vida. As evidências sugerem que o BPN é um determinante relevante de morbidade e mortalidade em grupos indígenas, que geralmente têm acesso limitado às políticas públicas de saúde e nutrição. O conhecimento da prevalência de BPN e de suas causas subjacentes pode contribuir com etapas essenciais para a prevenção de seus efeitos sobre a saúde. O estudo teve como objetivo estimar as prevalências de BPN, prematuridade e restrição de crescimento intra-uterino (RCIU) e investigar seus determinantes na primeira coorte de nascimentos indígenas no Brasil. MéTODOS: Este estudo transversal utilizou dados de linha de base coletados da primeira coorte de nascimentos indígenas no Brasil, a Coorte de Nascimentos Guarani. O Brasil é um dos países com maior diversidade étnica do mundo, com 305 povos indígenas e 274 línguas nativas. Os Guarani são uma das cinco maiores etnias, com aldeias localizadas principalmente na região sul. Todos os nascimentos únicos de 1º de junho de 2014 a 31 de maio de 2016 foram selecionados em 63 aldeias indígenas Guarani nas regiões Sul e Sudeste. Foi realizada regressão logística múltipla hierárquica. RESULTADOS: As taxas de prevalência de BPN, prematuridade e RCIU foram 15,5, 15,6 e 5,7%, respectivamente. As chances de BPN foram menores em recém-nascidos de mães que vivem em casas de tijolo e argamassa (OR: 0,25; IC 95%: 0,07-0,84) e foram maiores em filhos de mães ≤20 anos de idade (OR: 2,4; IC 95%: 1,29-4,44) e com anemia crônica antes da gravidez (OR: 6,41; IC 95%: 1,70-24,16). A prematuridade foi estatisticamente associada ao tipo de fonte de energia para cozinhar (fogão a lenha - OR: 3,87; IC 95%: 1,71-8,78 e fogueiras - OR: 2,57; IC 95%: 1,31-5,01). RCIU foi associado à primiparidade (OR: 4,66; IC 95%: 1,68-12,95) e anemia materna crônica antes da gravidez (OR: 7,21; IC 95%: 1,29-40,38). CONCLUSõES: Idade materna, estado nutricional e paridade, condições de moradia e exposição à poluição interna foram associados com resultados perinatais na população indígena Guarani. Esses resultados indicam a necessidade de investir no acesso e melhoria da assistência pré-natal; também no fortalecimento do Subsistema de Saúde Indígena, e em ações intersetoriais para o desenvolvimento de políticas habitacionais e de saneamento e melhorias ambientais ajustadas às necessidades e conhecimentos dos povos indígenas.

"Weathering the storm:" Mothers' and fathers' experiences of parenting a preterm infant.

Parenting preterm infants is a unique experience distinct from parenting full-term infants, characterized by a delayed transition to parenthood and limited caregiving opportunities. This study explored mothers' and fathers' lived experiences of parenting during infancy in the context of preterm birth. Semistructured qualitative interviews were conducted with 13 parents (6 fathers, 7 mothers) of preterm infants. Data were analyzed using interpretative phenomenological analysis. Four superordinate themes emerged: (a) An unnatural disaster: The traumatic nature of preterm birth, (b) The immediate aftermath: Disconnected and displaced, (c) Breaking the ice: Moving from frozen to melted, and (d) Aftershocks: Transitioning home. Both parents experienced preterm birth as traumatic. Similarities and differences in mothers' and fathers' experiences were identified. Preterm birth posed challenges for nurturant and social caregiving and resulted in anxiety, hypervigilance, and overprotective parenting behavior. The results highlight the need for trauma-informed care and further research developing and testing empirically based interventions.

Criar a infantes nacidos prematuramente es una experiencia única, distinta de criar a infantes nacidos a los nueve meses, caracterizada por una transición retrasada al hecho de ser padres y por oportunidades limitadas de prestación de cuidados. Este estudio exploró las experiencias de crianza vividas por las mamás y los papás durante la infancia dentro del contexto del nacimiento prematuro. Se llevaron a cabo entrevistas cualitativas semiestructuradas con 13 progenitores (6 papás, 7 mamás) de infantes nacidos prematuramente. Se analizó la información usando el Análisis Fenomenológico Interpretativo. Surgieron cuatro temas superiores: (i) Un desastre no natural: La naturaleza traumática del nacimiento prematuro; (ii) Las consecuencias inmediatas: Desconectados y desplazados; (iii) El rompimiento del hielo: Pasar de estar congelado a derretirse; y (iv) La conmoción posterior: En transición a casa. Ambos padres experimentaron el nacimiento prematuro como traumático. Se identificaron las similitudes y las diferencias en las experiencias de las mamás y de los papás. El nacimiento prematuro presentó retos para el cuidado de crianza y social y resultó en ansiedad, excesiva vigilancia y conducta de crianza sobreprotectora. Los resultados subrayan la necesidad de un cuidado fundamentado en la comprensión del trauma y de una investigación futura que desarrolle y examine las intervenciones con base empírica.

Le parentage de nourrissons prématurés est une expérience unique distincte du parentage de nourrissons à terme, caractérisée par une transition retardée au parentage et par des opportunités de prendre soin du bébé limitées. Cette étude a exploré les expériences vécues de parentage des mères et des pères durant la petite enfance dans le contexte d'une naissance prématurée. Des entretiens qualitatifs semi-structurés ont été faits avec 13 parents (6 pères, 7 mères) de nourrissons prématurés. Les données ont été analysées en utilisant l'Analyse Interprétative Phénoménologique. Quatre thèmes sur-ordonnés ont émergé : (i) Un désastre contre nature : la nature traumatique de la naissance prématurée, (ii) Le lendemain immédiat : déconnecté et déplacés, (iii) La glace brisée : de l'état de glace au dégel, et (iv) Les secousses secondaires : la transition au domicile. Les deux parents ont fait l'expérience de la naissance prématurée comme étant traumatique. Les similarités et les différences dans les expériences des mères et des pères ont été identifiées. La naissance prématurée s'est avérée difficile pour les soins nourriciers et sociaux et a résulté en anxiété, hypervigilance et en comportement de parentage surprotecteur. Les résultats de l'étude mettent en valeur le besoin de soin tenant en compte le trauma et de procéder à des recherches plus approfondies sur le développement et le test d'interventions basées sur des faits empiriques.

The mediating role of the therapeutic alliance in understanding early discontinuance.

Objective: The objective of this study was to test whether the therapeutic alliance mediated the relationship between previously identified predictors of premature termination and dropout during the first three sessions of treatment. Method: In this naturalistic study, 994 cases receiving individual, couple and family, or high-conflict coparenting therapy provided demographic information and completed assessments prior to treatment. Following the first session, clients completed a measure of the therapeutic alliance. Two hundred and five (20.6%) discontinued therapy prior to the fourth session. Logistic and ordinary least squares regression was used across m = 20 imputed datasets to examine the effect of pressure to attend therapy, age, gender, education, distress, therapy format, and therapist experience on whether clients continued in therapy and whether the alliance mediated this relationship. Results: After controlling for age, therapist experience, education, and pressure to attend therapy; general distress and participating in high-conflict coparenting were associated with higher rates of early termination. The effect of both distress and therapy format on dropout, however, was mediated by the therapeutic alliance. Conclusions: By focusing on improving the therapeutic alliance with high-conflict coparenting cases as well as clients with higher levels of distress, therapists may be able to increase client retention.

Association between affective disorders presenting before and during pregnancy and pre-term birth, considering socio-demographic factors, obstetric factors, health conditions, and use of medication.

OBJECTIVE: To study the relationship between maternal affective disorders (AD) before and during pregnancy, and pre-term birth. DESIGN: Retrospective observational study. LOCATION: Sexual and reproductive health units at the Institut Català de la Salut (ICS) in Catalonia, Spain. PARTICIPANTS: Pregnant women with a result of live-born child from 1/1/2012 to 30/10/2015. INTERVENTIONS: Data were obtained from the ICS Primary Care electronic medical record. MAIN MEASUREMENTS: Diagnosis of AD before and during pregnancy, months of pregnancy, and possible confusion factors were collected. Descriptive statistical analysis (median, interquartile range, and absolute and relative frequency), bivariate analysis (Wilcoxon test and Chi-square test), and multivariate analysis (logistic regression) were performed. RESULTS: 102,086 women presented valid information for the study. Prevalence of AD during pregnancy was 3.5% (4.29% in pre-term and 3.46% in term births; p<0.004). Pregnant women with pre-term births presented a higher age, smoking habit, lower inter-pregnancy interval, and a lower socio-economic status. Pre-term birth was significantly associated to previous history of stress and dissociative disorder (SDD), anxiety, obsessive-compulsive disorder (OCD) and eating disorders (ED), and use of antidepressants. It was also associated to abuse of alcohol, smoking, and use of psychoactive substances, as well as SDD, ED, use of antipsychotics, and divorce during pregnancy. Multivariate analysis confirmed the relationship between pre-term birth and history of AD, SDD, ED, and smoking, but not with AD during pregnancy. CONCLUSIONS: Examining the previous history of SDD and ED in pregnant women, and SDD, and ED during pregnancy is highly relevant to avoid pre-term birth.

[Frecuencia y gravedad de la retinopatía del prematuro en una unidad de cuidados intensivos neonatales].

INTRODUCTION: Retinopathy of prematurity (ROP) is a disease where retinal blood vessels do not develop normally and may cause visual damage and blindness. OBJECTIVE: To determine the frequency and severity of ROP in preterm newborns. METHOD: A descriptive, comparative study was carried out within the 2009-2013 period. Patients' general characteristics were recorded, including gestational age and postmenstrual age at the moment of ophthalmologic examination, as well as ROP severity and type of treatment. RESULTS: A total of 326 preterm newborns were included: 47.8 % (n = 156) had ROP; in 21.1 % it was severe (stage ≥ 3). Median gestational age was 28 weeks in preterm newborns with ROP, median birth weight was 1000 g, and median postmenstrual age at ophthalmological examination was 36 weeks. Of the infants with ROP, 71.1 % received treatment: 63.4 % of those who had mild ROP and 100 % of those with severe ROP. CONCLUSIONS: ROP frequency was high, higher than that reported in developed countries and similar to that in developing countries. The frequency of severe ROP was also higher. It is necessary for effective programs for the detection and opportune treatment of ROP to be established.

INTRODUCCIÓN: La retinopatía del prematuro (ROP) es una enfermedad en la que los vasos sanguíneos de la retina no se desarrollan normalmente, lo que puede ocasionar daño visual y ceguera. OBJETIVO: Identificar la frecuencia y gravedad de la ROP en recién nacidos prematuros. MÉTODO: Estudio descriptivo comparativo realizado en el periodo 2009-2013. Se registraron características generales de los pacientes, edad posnatal y edad posconcepcional al momento de la exploración oftalmológica, así como gravedad y tratamiento de la ROP. RESULTADOS: Se incluyeron 326 recién nacidos prematuros: 47.8 % (n = 156) tuvo ROP, en 21.1 % fue grave (estadio ≥ 3). La mediana de la edad gestacional fue de 28 semanas en los recién nacidos prematuros con ROP, el peso al nacer fue de 1000 g y la edad posconcepcional a la exploración oftalmológica fue de 36 semanas. De los niños con ROP, 71.1 % recibió tratamiento, 63.4 % de aquellos que tuvieron ROP leve y 100 % de aquellos con ROP grave. CONCLUSIONES: La frecuencia de ROP fue alta, mayor a la reportada en los países desarrollados y similar a la de otros países en desarrollo. La frecuencia de ROP grave también fue mayor. Es necesario establecer programas efectivos de detección y tratamiento oportuno de ROP.

THE FEASIBILITY OF USING "PREMIESTART," A MOTHER-PREMATURE INFANT INTERACTION PROGRAM, ON A NEONATAL UNIT IN ENGLAND.

This article explores the feasibility of running "PremieStart," a nine-individual-session maternal-premature infant interaction program, within a neonatal unit (NNU) in England. Four mothers of premature infants completed seven sessions on the NNU and two at home. Mothers and NNU staff provided feedback on PremieStart. Measures of maternal-infant relationship, maternal well-being, and maternal reflective functioning were completed before and after intervention. Thematic analysis of mothers' feedback highlighted the emotional, but cathartic, experience of engaging with PremieStart. NNU staff feedback indicated the need to include them more in PremieStart. Both mothers and staff were supportive of future implementation of PremieStart and highlighted the ongoing need for psychological support on the NNU. PremieStart was implemented with positive feedback from mothers and staff, with support shown for the continued use of PremieStart in the NNU. However, for future implementation, the self-report outcome measures need reviewing, and more involvement of fathers and NNU staff is needed. In addition, a larger sample with a control group should be utilized.

SUPPORTING PRETERM INFANT ATTACHMENT AND SOCIOEMOTIONAL DEVELOPMENT IN THE NEONATAL INTENSIVE CARE UNIT: STAFF PERCEPTIONS.

The infant-parent relationship has been shown to be of particular significance to preterm infant socioemotional development. Supporting parents and infants in this process of developing their relationships is an integral part of neonatal intensive care; however, there is limited knowledge of NICU staff perceptions about this aspect of care. To explore NICU staff perceptions about attachment and socioemotional development of preterm infants, experience of training in this area and the emotional impact of their work. A cross-sectional questionnaire survey of staff perceptions of the emotional experiences of parents and the developing parent-infant relationship in an NICU was conducted in a Level III NICU, after pilot testing, revision, and ethical approval. Fifty-seven (68%) of NICU staff responded to the survey. Respondents identified parents' emotional experiences such as "anxiety," "shock," "loss of control," and "lack of feelings of competence as parents" as highly prevalent. Infant cues of "responding to parent's voice" and "quieting-alerting" were ranked most highly; "crying" and "physiological changes" were ranked lowest. Preterm infant medical risk, maternal emotional state, and mental health are perceived to impact most highly on the developing relationship, as compared with infant state or behavior and socioeconomic factors. Fifty-three (93%) respondents felt confident, and 50 (87.8%) felt competent discussing their emotional experiences with parents. Fifty-four (95%) responded that attending to these areas was an integral part of their role; however, staff had seldom received education in this area. Respondents also perceived that specific psychological support for parents was lacking both during and after the infant's discharge. While all staff surveyed perceived the nature of their work to be emotionally stressful, there were differences among NICU staff disciplines and with years of experience in the NICU in terms of their perceptions about education in this area, the place of supervision for staff, and in relation to opportunities to discuss the emotional impact of the work on staff. NICU staff perceive their role as integral to supporting the developing parent-infant relationship and preterm infant socioemotional development; however, education in this area and provision of specific psychological support are lacking. Opportunities for staff to discuss and reflect on this aspect of their work should be developed and evaluated given the essential, but emotionally challenging, nature of their work with preterm babies and their parents.

PREMATURITY, NEONATAL HEALTH STATUS, AND LATER CHILD BEHAVIORAL/EMOTIONAL PROBLEMS: A SYSTEMATIC REVIEW.

Preterm birth can impact on child development. As seen previously, children born preterm present more behavioral and/or emotional problems than do full-term counterparts. In addition to gestational age, neonatal clinical status should be examined to better understand the differential impact of premature birth on later developmental outcomes. The aim of the present study was to systematically review empirical studies on the relationship between prematurity, neonatal health status, and behavioral and/or emotional problems in children. A systematic search of the PubMed, PsycINFO, Web of Science, and LILACS databases for articles published from 2009 to 2014 was performed. The inclusion criteria were empirical studies that evaluated behavioral and/or emotional problems that are related to clinical neonatal variables in children born preterm. Twenty-seven studies were reviewed. Results showed that the degree of prematurity and birth weight were associated with emotional and/or behavioral problems in children at different ages. Prematurity that was associated with neonatal clinical conditions (e.g., sepsis, bronchopulmonary dysplasia, and hemorrhage) and such treatments as corticoids and steroids increased the risk for these problems. The volume and abnormalities of specific brain structures also were associated with these outcomes. In conclusion, the neonatal health problems associated with prematurity present a negative impact on later child emotional and adapted behavior.

[Nursing interventions on the physical environment of Neonatal Intensive Care Units]. / Intervenciones enfermeras sobre el ambiente físico de las Unidades de Cuidados Intensivos Neonatales.

The objectives of this study are to analyse nursing interventions regarding noise and lighting that influence neurodevelopment of the preterm infant in the Neonatal Intensive Care Unit. A review of the literature was performed using the databases: Cuiden Plus, PubMed, IBECS and Cochrane Library Plus. The inclusion and exclusion criteria were established in accordance with the objectives and limits used in each database. Of the 35 articles used, most were descriptive quantitative studies based on the measurement of sound pressure levels and lighting in the Neonatal Intensive Care Units. The countries included in this study are Brazil and the United States, and the variables analysed were the recording the times of light and noise. Based on the high levels of light and noise recorded in the Neonatal Intensive Care Units, nursing interventions that should be carried out to reduce them are described. The evidence indicates that after the implementation of these interventions, the high levels of both environmental stimuli are reduced significantly. Despite the extensive literature published on this problem, the levels of light and noise continue to exceed the recommended limits. Therefore, nurses need to increase and enhance their efforts in this environment, in order to positively influence neurodevelopment of premature newborn.

[Nutritional status of adolescents from a cohort of preterm children]. / Estado nutricional de adolescentes pertenecientes a una cohorte de niños nacidos prematuros.

INTRODUCTION: Catch-up growth in preterm-born children occurs in the first months of life, but in some cases, growth recovery takes place in adolescence. The objective of this study was to study the growth and development of preterm-born adolescents from a cohort of preterm infants born between 1995 and 1996, who resided in the cities of Chillán and San Carlos in the Biobío Region, Chile. The results were then compared with term-born adolescents. SUBJECTS AND METHOD: A sample of 91 children from the cohort was studied and compared with 91 term-born adolescents matched for gender, age, and attendance at the same educational institution. The nutritional status was assessed by BMI-for-age, height-for-age, body composition by skinfold, cardiovascular risk due to blood pressure, and waist circumference. RESULTS: There was 23.0% and 24.1% overweight and obesity in preterm-born and term-born adolescents, respectively, with 25.5% of preterm-born and small for gestational age adolescents vs. 14.5% of those born adequate for gestational age were overweight. Lower height was observed in 16.5% and 5.5% of the preterm-born and term-born adolescents, respectively, and with a higher proportion of girls (P<.04). Preterm-born adolescents had a more fat mass than the controls, particularly in the suprailiac skinfold. No significant differences were found in blood pressure and waist circumference. CONCLUSIONS: The results indicate that there is a group of preterm-born children who do not recover height during adolescence, especially girls.

[Intrauterine growth and biochemical levels in cord blood samples in infants less than 31 weeks gestation]. / Perfil bioquímico en sangre de cordón en prematuros extremos y crecimiento fetal.

INTRODUCTION: The use of greater amounts of protein and energy during the first week of life is associated with hypophosphataemia in extreme preterm babies. The lowest phosphorus levels are described in intrauterine growth restricted (IUGR) babies. OBJECTIVES: To describe biochemistry levels in cord blood plasma in extreme premature, adequate and small for gestational age babies (AGA/SGA) and their relationship with plasma calcium and phosphorus levels during the first week of life. PATIENTS AND METHOD: A descriptive clinical study was performed in the Neonatology Service at Hospital Dr. Sótero del Río during 2013 and 2014. A biochemical analysis of cord blood was performed on 43 premature babies, as well as plasma calcium and phosphorus levels during the first week. The adequacy for gestational age was obtained using Alarcón- Pittaluga growth curves. Statistical significance was P<.05. RESULTS: Cholesterol, transaminases, albumin and creatinine levels were similar for both AGA and SGA babies. Levels of pH, phosphorus, calcium and alkaline phosphatase were significantly lower in SGA babies. Urea nitrogen, uric acid and triglycerides levels were higher in SGA. The analysis during the first week showed a strong reduction in phosphorus levels, as well as an increase in calcium levels in proportion to the decrease in phosphorus in the SGA sub- group. CONCLUSIONS: Intrauterine malnutrition in preterm babies is expressed in the modulation of plasma levels of calcium, phosphorus, alkaline phosphatase, urea nitrogen, uric acid and triglycerides. During post-natal life, when nutritional intake begins, a decrease in phosphorus and an increase in calcium levels appear, consistent with insufficient phosphorus intake during this period.

The ABCs of transfontanellar ultrasound and more. / El ABC de la ecografía transfontanelar y más.

Transfontanellar ultrasound is widely used to study neonatal neuroanatomy and disease. This technique has many advantages, such as the absence of ionizing radiation and its wide availability, portability, and low cost. The development of more powerful ultrasound scanners and improved microcurved and linear probes of different frequencies have resulted in improved image quality. To take full advantage of this technique, it is important to know the normal and pathologic anatomy in neonates. Transfontanellar ultrasound is the first-line technique for studying short-term and mid-term complications in premature newborns. In full-term newborns, it is very useful in many clinical situations, making it possible to select which patients will benefit from other techniques that are more invasive or more expensive, or that require sedation, such as MRI. The disadvantages of the technique are that it is operator dependent and that an appropriate acoustic window is necessary. It also has limitations in the study of obstetric trauma, in the evaluation of complex malformations, and in the assessment of damage to white matter. With a basic understanding of neonatal neurology, the appropriate equipment, and a careful technique taking advantage of the different fontanels, transfontanellar ultrasound is a reliable method that makes it possible to diagnose and follow up both congenital and acquired conditions in neonates.
