Infant massage as a stress management technique for parents of hospitalized extremely preterm infants.

Mothers of infants born extremely preterm requiring prolonged medical intervention in the Neonatal Intensive Care Unit (NICU) are at high risk of developing stress. Parent-administered infant massage is a well-established, safe intervention for preterm infants with many developmental benefits, but the published literature has mostly examined its impact on infants and parents through self-reported or observational measures of stress. The aim of this study was to measure salivary cortisol, a biomarker for stress, in extremely preterm infants and their mothers immediately pre and post parent-administered infant massage in order to detect potential changes in physiologic stress. Twenty-two mother-infant dyads completed massage education with a physical or occupational therapist. All dyads provided salivary cortisol samples via buccal swab immediately pre- and post-massage at the second session. Of mothers determined to be "cortisol responders" (15/22), salivary cortisol levels were lower after massage (pre-minus post-level: -26.47 ng/dL, [CI = -4.40, -48.53], p = .016, paired t-test). Our primary findings include a clinically significant decrease (as measured by percent change) in maternal cortisol levels immediately post parent-administered massage, indicating decreased physiological stress. Integration of infant massage into NICU clinical practice may support maternal mental health, but further powered studies are necessary to confirm findings.

Las madres de infantes nacidos extremadamente prematuros en la Unidad de Cuidado Intensivo Neonatal (NICU) se encentran bajo alto riesgo de desarrollar estrés. El masaje que una madre le da al infante es una intervención segura, bien establecida, para infantes prematuros, con muchos beneficios de desarrollo, aunque la información publicada disponible ha examinado por la mayor parte el impacto del masaje en los infantes y progenitores por medio de medidas de estrés auto reportadas o de observación. El propósito de este estudio fue medir el cortisol salival, un biomarcador de estrés, en infantes extremadamente prematuros y sus madres inmediatamente antes y después del masaje que la madre le da, para detectar posibles cambios en el estrés fisiológico. Veintidós díadas madre-infante completaron 2 sesiones educativas de masaje con un terapeuta físico u ocupacional. Todas las díadas aportaron muestras de cortisol salival por medio de hisopado bucal inmediatamente antes y después del masaje en la segunda sesión. Los niveles de cortisol en infantes no fueron suficientes para el análisis. De las madres a quienes se les determinó haber dado "respuesta de cortisol" (15/22), los niveles de cortisol salival fueron más bajos después del masaje (nivel antes menos nivel después: −26.47 ng/dL, [CI = −4.40, −48.53]. p = .016, prueba-t pareada). Entre nuestros resultados primarios se incluye una baja clínicamente significativa (tal como fue medida por el cambio porcentual) en los niveles de cortisol materno inmediatamente después del masaje. Estos resultados sugieren que el masaje dado por la madre a infantes prematuros pudiera reducir el cortisol materno, un marcador fisiológico de estrés.

Development and nationwide implementation of a postdischarge responsive parenting intervention program for very preterm born children: The TOP program.

A previous randomized controlled trial has suggested the effectiveness of a Dutch postdischarge responsive parenting program for very preterm (VPT) infants, indicating that nationwide implementation was justified. This paper describes the development and nationwide implementation of the intervention, known as the TOP program, which consisted of three phases. In the preparation phase (2006-2010), a theory of change and the structure of the TOP program were developed, and funding for phase two, based on a positive Business Case, was obtained. In the pilot implementation phase (2010-2014), intervention strategies were developed for a real-world setting, capacity and adoption were increased, systematic evaluations were incorporated, and sustained funding was obtained. In the full-implementation phase (2014-2019), all Dutch Healthcare Insurers reimbursed the TOP program, enabling VPT infants to participate in the program without charge. By 2018, the number of interventionists that provided the TOP program had increased from 37 to 91, and all level III hospitals and 65% of regional hospitals in the Netherlands referred VPT infants. Currently, the program reaches 70% of the Dutch target population and parental satisfaction with the TOP program is high. After a 12-year implementation period, the TOP program forms part of routine care in the Netherlands.

Un previo ensayo controlado al azar ha sugerido la eficacia de un programa holandés sobre la crianza sensible para infantes muy prematuros (VPT) posterior al momento en que se les dio de alta, indicando que la implementación a lo largo de toda la nación era justificada. Este artículo describe el desarrollo y la implementación a nivel de toda la nación de la intervención, conocida como el programa ToP, el cual consistía de tres fases. En la fase de preparación (2006-2010), se desarrollaron una teoría de cambio y la estructura del programa ToP, y se obtuvieron los fondos para la fase dos, con base en un Caso de Negocios (BC) positivo. En la fase piloto de implementación (2010-2014), se desarrollaron estrategias de intervención para un escenario del mundo real, se aumentaron la capacidad y la adopción, se incorporaron evaluaciones sistemáticas y se obtuvieron fondos para mantener el programa. En la fase de implementación completa (2014-2019), todas las Aseguradoras Holandesas del Sector Salud reembolsaron el costo del programa ToP, permitiéndoles a los infantes VPT participar en el programa sin costo alguno. Para 2018, el número de practicantes de la intervención que prestaban el servicio del programa ToP había aumentado de 37 a 91, y todos los hospitales del nivel III y 65% de los hospitales regionales en Holanda refirieron los infantes VPT al programa. Actualmente, el programa llega a 70% de la población holandesa para la cual está destinado y la satisfacción de los padres con el programa ToP es alta. Después de un período de implementación de 12 años, el programa ToP forma parte del cuidado de salud rutinario en Holanda.

Un essai contrôlé randomisé précédent a suggéré l'efficacité d'un programme hollandais de sensibilité de parentage après la sortie de l'hôpital pour les nourrissons grands prématurés (GP ici en français), indiquant qu'une mise en œuvre au niveau national était justifiée. Cet article décrit le développement et la mise en œuvre au niveau national de l'intervention, connue en tant que ToP program, qui a consisté en trois phases. Dans la phase de préparation (2006-2010), une théorie du changement et la structure du programme ToP a été développée, et le financement pour la phase deux, basée sur une Etude de Cas positive, a été sécurisé. Dans la phase pilote d'implémentation (2010-2014) des stratégies d'intervention ont été développées pour un contexte réel, la capacité et l'adoption ont été augmentées, les évaluations systématiques ont été incorporées, et un financement durable a été sécurisé. Dans la pleine phase de mise en œuvre (2014-1029), tous les Assurances Santé Hollandaises ont remboursé le programme ToP, permettant aux nourrissons GP de participer au programme sans coût. En 2018 le nombre de prestataires qui offraient le programme ToP a augmenté de 37 à 91, et tous les hôpitaux de niveau III ainsi que 65% des hôpitaux régionaux aux Pays Bas ont envoyé les nourrissons GP au programme. En ce moment le programme atteint 70% de la population cible hollandaise et la satisfaction parentale avec le programme ToP est élevée. Après une période de mise en œuvre de 12 ans le programme ToP fait partie des soins de routine aux Pays Bas.

PREDICTING ATTENDANCE OF A PREVENTIVE PARENTING INTERVENTION FOR VERY PRETERM INFANTS.

Preventive parenting interventions can experience challenges in maximizing dosage, or the amount of intervention received by parents. This study examined the associations of baseline mother, father, and very preterm infant (VPT; <32 weeks) characteristics with satisfactory intervention attendance of the family within a randomized controlled trial of Baby Triple P for Preterm Infants (Colditz et al., 2015). Mothers (n = 160) and fathers (n = 115) completed questionnaires prior to the randomization of family units (n = 160) to receive the intervention. Satisfactory session attendance (seven or eight sessions of eight in total) was achieved by 114 families (71.25%). In the logistic model for mothers, satisfactory attendance of the family was more likely when infants were extremely low birth weight (ELBW), odds ratio (OR) = 2.81, 95% confidence interval (CI) [1.16, 6.80], when the mother had a university, OR = 11.38, 95% CI [4.03, 32.19], or trade-certificate-level education, OR = 4.97, 95% CI [1.93, 12.84], or when she was not under financial stress, OR = 3.53, 95% CI [1.34, 9.28]. A similar pattern of results was found in the model for fathers. Session attendance of preventive parenting interventions for VPT infants may be improved by increasing the engagement of parents with infants not born ELBW, who have lower education, or are experiencing financial stress.

FATHER-CHILD PLAY DURING THE PRESCHOOL YEARS AND CHILD INTERNALIZING BEHAVIORS: BETWEEN ROBUSTNESS AND VULNERABILITY.

Play observations with a total of 400 toddlers and preschoolers were videotaped and rated for Intensity and Quality of play with their parents. Parents were asked about perceived stress and personality characteristics (Big 5). Child's motor, cognitive skills, temperament, and internalizing behaviors were assessed. Study 1 investigated the robustness of play across child age and gender, and examined differences between fathers and mothers. Study 2 explored the vulnerability of play with fathers of children born preterm (PT-fathers) and fathers who had experienced adverse childhoods (AC-fathers). Study 3 investigated child internalizing behaviors. Intensity of play was maintained almost independently of child age and gender. It was similar for AC- and PT-fathers, and similar to maternal Intensity. In contrast, paternal Quality of play was higher with boys and independent of fathers' personality and perceived parenting stress whereas maternal Quality of play was higher with girls and linked to mothers' perceived parenting competence, acceptability of the child, and neuroticism. AC-fathers scored significantly low on Quality, as did PT-fathers, but the Quality of their play became better with growing child age, birth weight, and cognitive (but not motor and temperament) scores. Finally, child internalizing behaviors were negatively related to paternal Quality of play.

[Need for resuscitation in preterm neonates less than 32 weeks treated with antenatal magnesium sulphate for neuroprotection]. / Necesidad de reanimación en prematuros menores de 32 semanas expuestos a sulfato de magnesio para neuroprotección fetal.

INTRODUCTION: Magnesium sulphate administration is recommended for foetal neuroprotection in pregnant women at imminent risk of early preterm birth. OBJECTIVE: To evaluate the relationship between intrapartum magnesium sulphate for foetal neuroprotection and delivery room resuscitation of preterm infants less 32 weeks. PATIENTS AND METHOD: A prospective observational study was conducted on preterm infants less 32 weeks exposed to magnesium sulphate for neuroprotection, and a comparison made with another historic group immediately before starting this treatment. Cases in both groups that had not reached lung maturity with corticosteroids were rejected. The rates of resuscitation, morbidity and mortality for each of the groups were analysed and compared. RESULTS: There was a total of 107 preterm, with 56 exposed to magnesium sulphate. Rate of advanced resuscitation were similar between the two groups. There were no other differences in mortality, invasive mechanical ventilation, time to first stool, and other comorbidities. CONCLUSIONS: Intrapartum magnesium sulphate for foetal neuroprotection was not associated with an increased need for intensive delivery room resuscitation and other morbidities in these cohorts of less than 32 weeks preterm infants.

Evidence on the benefits of probiotics for preterm infants.

Introduction: This article reviews the evidence for the use of different strains of probiotics in the prevention of prevalent pathologies in premature neonates. A systematic review was conducted of the use of probiotics in neonates with less than 37 weeks of gestational age, based on a search for systematic reviews and observational and experimental studies performed during the period from January 2014 to February 2021. For this purpose, the PubMed, MEDLINE and Cochrane Library databases were consulted. The aim of this article was to review the existing data on the relationship between the administration of probiotics (with different strains and doses) and the risk of necrotising enterocolitis, mortality, late sepsis and other disease parameters in premature infants. The literature search obtained 240 articles, of which we selected 16, representing a total sample of over 200,000 premature infants. Analysis of the data obtained reveals statistical evidence that the combined administration of probiotics (especially of Lactobacillus and Bifidobacterium strains) reduces the incidence of grade II or higher necrotising enterocolitis, all-cause mortality, late sepsis, length of hospital stay and time until complete enteral nutrition is achieved. However, no benefits were apparent with respect to alleviating bronchopulmonary dysplasia, retinopathy of prematurity or intraventricular haemorrhage. Further research is needed to determine the most appropriate strains, doses and treatment duration for preterm infants to achieve the health benefits identified.

Introducción: En este artículo se revisa la evidencia del uso de las diferentes cepas de probióticos en la prevención de diversas patologías prevalentes en recién nacidos prematuros. Se ha realizado una revisión sistemática sobre el uso de probióticos en recién nacidos de menos de 37 semanas de edad gestacional, realizando una búsqueda de revisiones sistemáticas, estudios observacionales y experimentales desde enero de 2014 hasta febrero de 2021. Para ello se han utlizado motores de búsqueda como PubMed, MEDLINE y la biblioteca Cochrane. El objetivo de este artículo fue revisar los datos existentes sobre la relación entre la administración de probióticos (con diferentes cepas y dosis) y el riesgo de enterocolitis necrotizante, mortalidad, sepsis tardía, y otros parámetros de enfermedad en prematuros. En la búsqueda se obtuvieron 240 artículos, de los que seleccionamos 16, obteniendo más de 200.000 recién nacidos prematuros como muestra. En esta revisión se muestra con evidencia estadística, que la administración combinada de probióticos (espcialmente cepas de Lactobacillus y Bifidobacterium) reducen la incidencia de NEC en grado II o mayor, mortalidad por todas las causas, sepsis tardía, días de estancia hospitalaria y tiempo en lograr nutrición enteral completa. No se han podido evidenciar beneficios en cuanto a la displasia broncopulmonar, retinopatía de la prematuridad y hemorragia intraventricular. Se precisan nuevos estudios para conocer las cepas, dosis y tiempo de tratamiento más adecuados en neonatos prematuros para lograr beneficios en salud.

The influence of parenteral protein intake on electrolyte disturbances in premature infants.

INTRODUCTION: Aggressive parenteral nutrition with delivery of high amino acid and energy doses is used to improve growth and neurodevelopmental outcomes in very low birth weight (VLBW) preterm infants. Recent findings, however, suggest that this approach may cause electrolyte imbalances. The aim of our study was to compare the prevalence of hypercalcaemia, hypophosphataemia, and hypokalaemia in 2 groups of preterm infants that received parenteral nutrition with different amounts of amino acids and to analyse perinatal and nutritional variables associated with the development of electrolyte imbalances. METHODS: We conducted a retrospective observational study comparing 2 groups of preterm infants born before 33 weeks' gestation with birth weights of less than 1500 g managed with parenteral nutrition. One of the groups received less than 3 g/kg/day of amino acids and the other received 3 g/kg//day of amino acids or more. We analysed the prevalence of electrolyte imbalances and possible associations with aggressive parenteral nutrition, adjusting for potential confounders. RESULTS: We studied 114 infants: 60 given less than 3 g/kg/day of amino acids (low-intake group) and 54 given at least 3 g/kg/day (high-intake group). The prevalence of electrolyte imbalances was similar in both groups. The prevalence of hypercalcaemia was 1.67% in the low-intake group and 1.85% in the high-intake group (P > .99), the prevalence of severe hypophosphataemia 11.7% vs 9.3%, and the prevalence of hypokalaemia 15.0% vs 11.1% (P > .99). A calcium to phosphorus ratio greater than 1.05 had a protective effect against hypophosphataemia (P = .007). CONCLUSIONS: We did not find an association between hypercalcaemia, hypophosphataemia, and hypokalaemia and the amino acid dose delivered by PN in the high-intake group of preterm infants.

Assessment of thyroid function in the preterm and/or very low birth weight newborn.

The screening program or early detection of congenital hypothyroidism is one of the greatest advances achieved in Pediatrics. Thyroid hormones are essential for brain development and maturation, which continue into the neonatal stage. Alterations in thyroid function in premature and underweight children in the first months of life causes irreversible damage to the central nervous system and is one of the most frequent and avoidable causes of mental retardation. Diagnosis in the neonatal period is difficult, so it requires an analytical study to be able to carry out the appropriate treatment. The relevance of this problem justifies its communication to all areas of pediatrics. The main objective is to avoid brain damage in these patients. Other aspects to optimize the adequate development of these children with all the necessary periodic controls and to achieve the inclusion of the diagnosis of thyroid alterations during the stay in neonatal units and in the first months of life, need to implement the resources of the health centers and continue advancing according to current knowledge. In this document, we will focus on the screening of preterm newborns VLBW (<32 weeks of gestation) and/or very low weight for gestational age (1500-1000 g VLBW or <1000 g) and the function evaluation protocol thyroid in premature babies. We update the diagnostic procedures, the essential and complementary tests required, the etiology and the differential diagnoses in this pathology.

Aerobic Capacity of Preterm Children with Very Low Birth Weight at School Age and its Associated Factors.

INTRODUCTION: Respiratory morbidities of preterm infants can cause significant ventilatory impairment thus compromising the aerobic capacity in childhood and adolescence. Therefore, the present study was conducted to evaluate the aerobic capacity in school age preterm children with VLBW and its associated factors. METHODS: A cross-sectional study was conducted among preterm born with VLBW and term children, both aged 6-9 years. An individualized symptom-limited treadmill testing protocol performed aerobic capacity. Measured variables: oxygen pulse (PuO2), percentage of maximum heart rate for age (%HR max), tidal volume/inspiratory capacity ratio (TV/IC), oxygen consumption (VO2) peak, and the ratio of the anaerobic threshold of gas exchange to the predicted percentage of maximum VO2 (VO2@LA/%VO2 max.pred.) were compared between groups. Univariate and multiple linear regression analyses were used to determine the factors associated with aerobic capacity. RESULTS: Thirty-four preterm and 32 term children were included. Similar VO2 peak and the other variables were observed. The development of bronchopulmonary dysplasia (BPD) and being obese/overweight was positively associated with %HR max. The Z-score for height/age and birth weight <1000g was positively associated with PuO2 and peak VO2, and negatively associated with overweight/obesity and female sex. CONCLUSIONS: Aerobic capacity was similar in both groups. Sex, development of BPD, birth weight <1000g and factors related to body growth, such as Z-score for height/age and overweight/obesity, were associated with aerobic capacity in preterm children with VLBW.

Retinopathy of prematurity, frequency and risk factors in very low birth weight infants.

Background: Retinopathy of prematurity (ROP) is the principal cause of blindness during childhood. The objective of this study was to analyze the frequency of ROP and risk factors associated with ROP in a cohort of very low birth weight infants. Methods: A cases (ROP) and controls (no ROP) study of infants less than 1500 g was conducted. Perinatal and neonatal variables were analyzed. For the statistical analysis, χ2 test, Student's t-test and Mann-Whitney's U-test were used. Results: For the study, 282 neonates were included: 152 (53.9%) with ROP and 130 (46.1%) without ROP. The most frequent stages observed were stage 1 and 2, with 139 (91.4%) patients, and stages 3 to 5, with only 13 patients (8.5%). In those neonates with ROP compared with neonates without ROP, the birth weight was less (902.7 vs. 1037.9 g) and the difference was significant (p < 0.0001). Also, the difference with gestational age (28.2 vs. 29.6; p < 0.0001), total ventilation days (32.8 vs. 16.1; p < 0.00001) and total oxygen days (87.7 vs. 62.6; p < 0.0001) was significant in neonates with ROP and neonates without the disease. Bronchopulmonary dysplasia, intraventricular hemorrhage and late onset sepsis were significant with patients with ROP. Conclusions: The frequency of ROP reported here is higher than the reported in Mexican population, with less cases of severe ROP. The neonatal surveillance in babies with less birth weight and gestational age is important to decrease the incidence of ROP.

Introducción: La retinopatía del prematuro (ROP) es una de las principales causas de ceguera infantil. La inmadurez y la exposición a oxígeno son algunos factores de riesgo. El objetivo de este artículo fue analizar la frecuencia y los factores de riesgo de ROP en una cohorte de recién nacidos menores de 1,500 g. Métodos: Se llevó a cabo un estudio de casos (con ROP) y controles (sin ROP) de recién nacidos menores de 1,500 g. Se analizaron variables prenatales y neonatales, y para su comparación se utilizaron las pruebas estadísticas t de Student, χ2 y U de Mann-Whitney. Resultados: Se analizaron 282 recién nacidos: 152 (53.9%) con ROP y 130 (46.1%) sin ROP. La mayor frecuencia se encontró en los estadios 1 y 2, con 139 pacientes (91.4%), seguidos de los estadios 3 a 5, con 13 pacientes (8.5%). En los pacientes con ROP, el peso al nacer fue menor (902.7 vs. 1037.9 g; p < 0.0001), así como la edad gestacional (28.2 vs. 29.6 semanas de gestación; p < 0.0001). Los días de ventilación (32.8 vs. 16.1; p < 0.00001) y los días de oxígeno requerido durante la estancia hospitalaria (87.7 vs. 62.6; p < 0.0001) fueron mayores en los pacientes con ROP. La displasia broncopulmonar, la hemorragia intraventricular y la sepsis tardía fueron comorbilidades significativas para el desarrollo de ROP. Conclusiones: En este estudio, la frecuencia de ROP fue mayor que la reportada en la población mexicana, con una baja proporción de formas graves. La vigilancia estrecha del manejo de los neonatos con menor peso y menos edad gestacional es fundamental para lograr disminuir esta enfermedad.

Uma travessia no contexto da prematuridade: da uti-neonatal até a casa / Un camino en el contexto de la prematuridad: de la uci neonatal al hogar / A path in the context of prematurity: from neonatal icu to home

RESUMO. Este estudo retrata, através de relatos e observações clínicas, o caminho percorrido por uma mãe para tornar-se suporte, porto ou casa, para seus bebês gêmeos, durante a internação em UTI neonatal e logo após a alta hospitalar. A investigação, que teve como base a abordagem psicanalítica de Donald Winnicott, emergiu de um recorte da pesquisa de mestrado da autora principal. A pesquisa ocorreu em dois momentos: I) acompanhamento da mãe e bebês durante a internação do recém-nascido na UTI-neonatal de um hospital geral de Porto Alegre durante um mês e nove dias com frequência semanal e II) acompanhamento após a alta através de visitas domiciliares. A segunda etapa teve início após uma semana da alta hospitalar e ocorreu durante um mês e 19 dias com frequência quinzenal. Para a coleta dos dados foram utilizados diários clínicos como um dispositivo na escuta das singularidades observadas em cada atendimento. Observou-se que a experiência de internação representou vivências de (des) continuidade para os bebês e mãe. O processo da travessia para casa representou uma inflexão importante em relação à sustentação corporal (e psíquica) dos bebês pela mãe. Destacamos ainda que o acompanhamento psicológico demonstrou ter sido importante para sustentar essa mãe ao longo da travessia e ajudá-la a se tornar 'casa' para seus recém-nascidos.

RESUMEN. Este estudio retrata, a través de informes y observaciones clínicas, el camino recorrido por una madre para convertirse en apoyo, puerto u hogar para sus bebés gemelos durante el ingreso a la UCI Neonatal y poco después del alta hospitalaria. La investigación se basó en el enfoque psicoanalítico de Donald Winnicott y se desarrolló en dos momentos: I) Seguimiento de la madre y los bebés durante la hospitalización en la UCI Neonatal de un hospital general de Porto Alegre durante un mes y nueve días con frecuencia semanal y II) Seguimiento tras el alta a domicilio. La segunda etapa se inició luego de una semana del alta hospitalaria y se desarrolló durante un mes y diecinueve días con una frecuencia quincenal. Para la recogida de datos se utilizaron diarios clínicos como dispositivo para escuchar las singularidades observadas en cada servicio. Se observó que la experiencia de hospitalización representó experiencias de (dis) continuidad para los bebés y la madre. El proceso de ir a casa representó una inflexión importante en relación al apoyo corporal (y psíquico) de los bebés por parte de la madre. También destacamos que la asistencia psicológica resultó ser importante para apoyar a esta madre durante todo el camino y ayudarla a convertirse en un 'hogar' para sus recién nacidos.

ABSTRACT. This study portrayed, through reports and clinical observations, the path taken by a mother to become support, harbor, or home, for her twin babies during admission to the Neonatal ICU and shortly after hospital discharge. Such investigation, based on Donald Winnicott's psychoanalytical approach, arose as a part of the first author's master's research. The research took place in two moments: I) Weekly follow-up of the mother and babies during the newborn's admission to the Neonatal ICU of a general hospital in Porto Alegre, state of Rio Grande do Sul, for one month and nine days, and II) Follow-up after discharge through home visits. The second stage started one week after hospital discharge and occurred for one month and nineteen days, with a fortnightly frequency. For data collection, clinical diaries were used as a device to listen to the singularities observed in each service. The hospitalization represented experiences of (dis) continuity for the babies and the mother. The journey process to home was an important inflection about the bodily (and psychic) support of babies by the mother. Psychological care proved essential to support this mother throughout the journey and help her become a 'home' for her newborns.

Vivências no processo de aleitamento materno de mães de recém-nascidos prematuros internados em um hospital público do municipio de Guarapuava-PR / Experiences in the breastfeeding process of mothers of preterm newborns admitted to a public hospital in the city of Guarapuava-PR

Objetivo: Descrever os relatos de vivências no processo de amamentação de mães de recém-nascidos prematuros. Método: Estudo qualitativo realizado com mães de recém-nascidos prematuros, internados em uma Unidade de Terapia Intensiva Neonatal, de um hospitalpúblico de Guarapuava-PR, no período de junho a julho de 2018, mediante aplicação de um instrumento com questões fechadas e outro com questões relacionadas à amamentação de prematuros. Foram incluídas no estudo mães que já haviam amamentado seus filhos ao seio ou por meio da ordenha mamária, e excluídas mães com idade inferior a 18 anos ou que apresentavam condições clínicas que as impediam de amamentar, cujos filhos estavam internados em período menor que três dias. Resultados: Participaram do estudo 10 mães de recém-nascidos prematuros, das quais 70% tinham idade gestacional de 32 a 36 semanas, 10% de 28 semanas e 20% de 29 semanas gestacionais. As mães relataram dificuldades em manter a pega e a sucção do leite materno e sentimentos de nervosismo, receberam apoio dos profissionais e familiares no incentivo à amamentação e no cuidado humanizado pela equipe de saúde. Conclusões: Diante do conhecimento das dificuldades encontradas pelas mães na amamentação de prematuros, é possível estabelecer medidas para evitar o desmame precoce, respeitando a autonomia da mãe no cuidado ao bebê.

Objective: To describe the breastfeeding experiences of mothers of preterm newborns. Methods: Qualitative study carried out with mothers of preterm newborns admitted to a Neonatal Intensive Care Unit at a public hospital in Guarapuava-PR, from June to July 2018, using a questionnaire instrument with closed questions and another with questions related to breastfeeding premature babies. The study included mothers who had already breastfed their children, and excluded mothers under the age of 18 or who had medical conditions that prevented them from breastfeeding, and whose children had been hospitalized for less than three days. Results: Ten mothers of preterm newborns took part in the study, 70% of whom had a gestational age of 32 to 36 weeks, 10% 28 weeks and 20% 29 weeks. The mothers reported difficulties in maintaining the latch and sucking breast milk, as well as feelings of nervousness. They received support from professionals and family members in encouraging breastfeeding and humanized care from the health team. Conclusion: With knowledge of the difficulties encountered by mothers in breastfeeding preterm babies, it is possible to establish measures to prevent early weaning, while respecting the mother's autonomy in caring for the baby.

[Impact of screening and treatment of low systemic blood flow in the prevention of severe intraventricular haemorrhage and/or death in pre-term infants]. / Impacto del cribado y tratamiento del bajo flujo sistémico en la prevención de hemorragia intraventricular grave y/o muerte en el prematuro.

OBJECTIVE: To assess the effect of a protocolised intervention for low systemic blood flow (SBF) in the occurrence of severe intraventricular haemorrhage (IVH) or death in pre-term infants. METHODS: A study with a quasi-experimental design with retrospective controls was conducted on pre-term infants of less than 30weeks of gestational age, born between January 2016 and July 2017, who were consecutively included in the intervention period. The control cohort included pre-term infants (born between January 2013 and December 2015) matched by gestational age, birth weight, and gender (two controls for each case). The cases of low SBF diagnosed according to functional echocardiography during the study period received dobutamine (5-10µg/kg/min) for 48hours. RESULTS: The study included 29 cases (intervention period) and 54 controls (pre-intervention period). Ten out of 29 (34.5%) infants received dobutamine for low SBF during the intervention period, with 3/29 (10.3%) cases of severe IVH and/or death compared to 17/54 (31.5%) in the control cohort (p=.032). There was an independent association between the intervention and a decreased occurrence of severe IVH/death after adjusting for confounding factors both in the logistic regression model [OR 0.11 (95%CI: 0.01-0.65), p=.015], as well as in the sensitivity analysis using inverse probability of treatment weighting [OR 0.23 (95%CI: 0.09-0.56); p=.001]. CONCLUSIONS: In this study with retrospective controls, a protocolised screening, and treatment for low SBF was associated with a decreased occurrence of severe IVH or death in preterm infants. Large, adequately powered trials, are needed in order to determine whether postnatal interventions directed at low SBF can improve neurological outcomes.

Limite de viabilidade de prematuros extremos atendidos em um hospital universitário / Limit of viability of extremely preterm infants treated at a university hospital / Límite de viabilidad de prematuros extremos atendidos en un hospital universitario

Objetivo: descrever o perfil de recém-nascidos com prematuridade extrema e identificar fatores associados a mortalidade segundo idade gestacional e o limite de viabilidade destes. Método: estudo observacional retrospectivo, com abordagem quantitativa, realizado em um hospital universitário do estado de Minas Gerais, desenvolvido de agosto de 2021 a janeiro de 2022. A amostra foi composta por 39 prontuários de prematuros extremos nascidos vivos. Foi realizada a análise descritiva das variáveis quantitativas usando medidas como média, desvio-padrão e valores mínimo e máximo. As variáveis categóricas foram descritas a partir de suas distribuições de frequência absoluta e percentual. Resultados: a maioria das gestantes são mulheres adultos-jovens, realizaram pré-natal e parto cesárea. Dos prematuros prevalece sexo masculino, idade gestacional de 25 semanas, evoluíram para óbito a maioria destes com idade gestacional de 23 e 24 semanas. Conclusão: o limite de viabilidade nesse serviço situa-se em uma idade gestacional igual ou maior que 25 semanas.

Objective: to describe the profile of newborns with extreme prematurity and to identify factors associated with mortality according to gestational age and their limit of viability. Method: a retrospective observational study, with a quantitative approach, carried out in a university hospital in the state of Minas Gerais, developed from August 2021 to January 2022. The sample consisted of 39 records of live-born extreme preterm infants. Descriptive analysis of quantitative variables was performed using measures such as mean, standard deviation and minimum and maximum values. Categorical variables were described from their absolute and percentage frequency distributions. Results: most pregnant women are young-adult women, who underwent prenatal care and cesarean delivery. Of the preterm infants, the male sex prevails, with a gestational age of 25 weeks, most of whom died at a gestational age of 23 and 24 weeks. Conclusion: the limit of viability in this service is at a gestational age equal to or greater than 25 weeks.

Determinación de valores de corte de 17 hidroxiprogesterona ajustados por edad gestacional para la pesquisa neonatal de la hiperplasia suprarrenal congénita / Assessment of gestational age-adjusted 17-hydroxyprogesterone cut-off values for neonatal screening of congenital adrenal hyperplasia

La pesquisa neonatal de hiperplasia suprarrenal congénita se realiza mediante la determinación de 17 hidroxiprogesterona (17OHP) en gotas de sangre seca en papel de filtro. Los bebés prematuros presentan valores más elevados que los bebés de término, siendo de utilidad contar con límites de corte apropiados. Nuestro objetivo fue actualizar los valores de corte de 17OHP ajustados por edad gestacional para la metodología en uso a nivel nacional por las jurisdicciones asistidas por el "Programa Nacional de Fortalecimiento de la Detección Precoz de Enfermedades Congénitas". La 17OHP se determinó utilizando el kit comercial de enzimo-inmunoanálisis (ELISA competitivo), Elizen Neonatal 17OHP Screening (Zentech, Bélgica). Se obtuvieron límites de corte utilizando percentiles de la distribución de los valores de 17OHP para cada edad gestacional. La sensibilidad obtenida fue 100%, especificidad 98,76 %, tasa de falsos positivos 1,24 % y el valor predictivo positivo 1,12 %. Destacamos la importancia de disponer de límites de corte adecuados a la población. La armonización de los mismos permitirá resultados comparables entre los programas regionales de pesquisa neonatal (AU)

Newborn screening for congenital adrenal hyperplasia is performed by the measurement of 17-hydroxyprogesterone (17OHP) in dried blood spots on filter paper. Premature infants have higher values than full-term infants, and appropriate cutoff values are useful. Our aim was to update the cut-off values of 17OHP adjusted for gestational age for the methodology used at a national level in regions assisted by the "National Program for Strengthening the Early Detection of Congenital Diseases". 17OHP was determined using the commercial enzyme-linked immunosorbent assay (competitive ELISA) kit, Elizen Newborn 17OHP Screening (Zentech, Belgium). Cut-off values were obtained using percentiles of the distribution of 17OHP values for each gestational age. Sensitivity was 100%, specificity 98.76%, false positive rate 1.24%, and positive predictive value 1.12%. It is important to have cut-off values that are adjusted to the population. Harmonization will allow for the comparison of results among regional newborn screening programs (AU)

Tamaño del léxico en niños(as) muy prematuros y prematuros extremos de 24 meses: un estudio transversal / Vocabulary size in very preterm and extremely preterm infants: a cross-sectional study

Las investigaciones muestran que un número importante de niños nacidos prematuros (antes de las 37 semanas de gestación) presentan dificultades en su desarrollo, entre ellas el desarrollo lingüístico. Las investigaciones previas indican que algunas complicaciones biomédicas, como la hemorragia intraventricular (los grados III y IV), la leucomalacia periventricular y la displasia broncopulmonar, incrementan la probabilidad de presentar alteraciones en el desarrollo de la cognición y/o del lenguaje, por lo que se hace necesario realizar investigaciones que proporcionen más información y con ello poder anticiparse a posibles consecuencias en los aprendizajes futuros de estos niños nacidos bajo la condición de prematuridad. Es así, que los objetivos de este estudio fueron medir el tamaño del léxico temprano en niños muy prematuros y prematuros extremos (con y sin complicaciones biomédicas) a los 24 meses de edad corregida, así como también determinar la asociación entre número de complicaciones biomédicas presentes y el tamaño del léxico. Para ello, se trabajó con 108 niños divididos en tres grupos: 39 niños prematuros de alto riesgo (con complicaciones biomédicas), 36 niños prematuros de bajo riesgo (sin complicaciones biomédicas asociadas a alteraciones del lenguaje y /o cognición) y 33 niños nacidos de término. Todos fueron evaluados con el Inventario II de Desarrollo de Habilidades Comunicativas MacArthur-Bates. Los resultados muestran que los niños nacidos de término tienen significativamente mayor tamaño del léxico que los prematuros, no existiendo diferencias en los resultados entre prematuros de bajo riesgo y los prematuros de alto riesgo. Por otra parte, el tamaño del léxico no presenta correlación con las complicaciones biomédicas.

Research shows that a significant number of children born preterm (before 37 weeks of gestation) have developmental difficulties, among them disturbances in language development. Studies indicate that some biomedical complications such as intraventricular hemorrhage (grades III and IV), periventricular leukomalacia, and bronchopulmonary dysplasia increase the probability of cognitive and/or language development disorders. Therefore, there is a need to conduct more studies that provide information that allows anticipating possible consequences in the learning process of children born prematurely. The aims of this study were to measure the early vocabulary size in very preterm and extremely preterm children (with and without biomedical complications) at 24 months of corrected age and to determine the association between the number of biomedical complications and vocabulary size. To that effect, we worked with 108 children divided into three groups: 39 high-risk preterm children (with biomedical complications), 36 low-risk preterm children (without biomedical complications associated with language and/or cognitive disturbances), and 33 full-term children. All children were evaluated using the MacArthur-Bates Communicative Development Inventory II. The results show that the vocabulary size of full-term children is significantly larger than that of preterm children and that no differences exist between the group of high-risk versus low-risk preterm children. On the other hand, vocabulary size does not correlate withbiomedical complications.

[Follow-up protocol for newborns of birthweight less than 1500 g or less than 32 weeks gestation]. / Protocolo de seguimiento para el recién nacido menor de 1.500 g o menor de 32 semanas de edad gestación.

The mortality of children with a birthweight of less than 1500g or with a gestational age of less than 32 weeks (<1500<32) has decreased significantly in the last 20 years or so. Given the higher risk of disability in these children, follow-up after hospital discharge is considered essential. In this document, the Follow-Up Group of the Spanish Society of Neonatology, in collaboration with the Spanish Society of Paediatric Primary Care, propose a follow-up protocol specific for the<1500<32, which has as its aim to standardise the activities and evaluations according to good practice criteria.

Contribuições e especificidades da clínica winnicottiana para a prematuridade: Evidências a partir de dois casos / Contributions and specificities of the Winnicottian clinic for prematurity: Evidence from two cases / Aportaciones y especificidades de la clínica de Winnicott para la prematuridad: Evidencia de dos casos

O presente estudo investigou as contribuições dos princípios e da técnica da clínica winnicottiana no atendimento a duas mães e seus bebês no contexto da prematuridade. No primeiro caso, a mãe tinha 20 anos e a filha nasceu com 27 semanas gestacionais, pesando 1.020 gramas, e permaneceu 81 dias no hospital; no segundo, a mãe tinha 21 anos e as filhas gêmeas nasceram com 27 semanas gestacionais, pesando 1.600 gramas, e permaneceram 49 dias no hospital. O atendimento foi realizado durante a internação dos bebês. O foco da análise dos resultados foi no processo do atendimento, considerando cinco eixos temáticos derivados dos atendimentos: tolerância e confiabilidade; setting constante e confiável; acompanhamento das mães nas primeiras aproximações das filhas; espaço para elaboração dos conflitos conjugais e familiares; e desafios e impasses da clínica winnicottiana para a prematuridade. Os resultados revelaram que os atendimentos auxiliaram as mães em suas dificuldades frente à maternidade, bem como para verbalizar e elaborar as culpas, as perdas, o luto e os medos que a experiência do nascimento prematuro agrega à maternidade.

The present study investigated the contributions of the principles and techniques of Winnicott's clinic in the care of two mothers and their babies in the context of prematurity. In the first case, the mother was 20 years old and the daughter was born at 27 weeks gestational age, weighing 1,020 grams, and stayed 81 days in the hospital. In the second, the mother was 21 years old and the twin daughters were born at 27 weeks gestational age, weighing 1,600 grams, and stayed 49 days in the hospital. Care was provided during the babies' hospitalization. The focus of the analysis of the results was on the process of care, considering five thematic axes derived from the sessions: tolerance and reliability; constant and reliable setting; support for the mothers in the first approaches to their daughters; room for the elaboration of conjugal and family conflicts; and challenges and impasses of the Winnicottian clinic for prematurity. The results revealed that the consultations helped the mothers in their difficulties facing maternity, as well as to verbalize and elaborate the guilt, losses, mourning and fears that the experience of premature birth adds to maternity.

Evolution of care indicators after an early discharge intervention in preterm infants. / Evolución de indicadores de cuidados tras una intervención de alta precoz en recién nacidos prematuros.

OBJECTIVE: To evaluate the evolution of health outcomes in preterm infants included in an early discharge programme. METHOD: Controlled, non-randomised trial with an intervention group and a control group children admitted to the Neonatal Intensive Care Unit of the University Hospital Virgen de las Nieves of Granada were included in the study. The intervention group comprised preterm infants admitted to the neonatal unit clinically stable, whose family home was located within 20km. from the hospital. They were discharged two weeks before the established time and a skilled nurse in neonatal care monitored them at home. The control group comprised infants who could not be included in home monitoring due to the distance to the hospital criterion or because their families did not give their consent and who received the usual care until their discharge. The study variables were the outcome indicators of the Nursing Outcomes Classification. RESULTS: Differences were found in the Nursing Outcomes Classification scores in the intervention group compared to the control group. CONCLUSIONS: The early discharge of preterm infants followed up at home by an expert nurse in neonatal care is a health service that achieves results in preparating parents for the care of their child, enabling them to learn about the health services, adapt to their new life, and establishbreastfeeding times. It constitutes safe intervention for children and is beneficial to parents.
