Moderating Effect of Changes in Perceived Social Support during Pregnancy on the Emotional Health of Mothers and Fathers and on Baby's Anthropometric Parameters at Birth.

(1) Background: this study is based on a model of how changes in protective factors may affect the emotional health of mothers and fathers and thus influence the development of the baby. Our research goal is to determine whether variations in perceived social support moderate levels of stress and depression during pregnancy and/or the effect of parents' emotional health on the baby's anthropometric parameters. (2) Methods: to achieve these aims, a longitudinal study was made of 132 couples and babies, who were evaluated at weeks 12 and 32 of gestation and at birth. Separate analyses were performed for the mothers and fathers, focused on the role of social support in moderating their levels of depression and stress during pregnancy, and the consequent impact on the baby. (3) Results: the results obtained show the moderating effects of changes in social support on maternal and paternal stress and depression. Reduced social support during pregnancy is associated with higher levels of stress and depression in both parents and with a high cephalisation index in their babies. (4) Conclusions: special attention should be paid to social support, which can have a strong impact on the evolution of emotional health during pregnancy and concomitantly on the development of the baby.

Oropharyngeal Colostrum Positively Modulates the Inflammatory Response in Preterm Neonates.

During the first days of life, premature infants have physiological difficulties swallowing, thereby missing out on the benefits of breastfeeding. The aim of this study is to assess the effects of oropharyngeal mother's milk administration in the inflammatory signaling of extremely premature infants. Neonates (n = 100) (<32 week's gestation and/or <1500 g) were divided into two groups: mother's milk group (n = 48), receiving 0.2 mL of oropharyngeal mother's milk every 4 h for the first 15 days of life, and a control group (n = 52), not receiving oropharyngeal mother's milk. Serum concentrations of interleukin (IL) IL-6, IL-8, IL-10, IL-1ra, tumor necrosis factor alpha (TNF-α), and interferón gamma (IFN-γ) were assessed at 1, 3, 15, and 30 days of postnatal life. Maternal and neonatal outcomes were collected. The rate of common neonatal morbidities in both groups was similar. The mother's milk group achieved full enteral feeding earlier, and showed a decrease in Il-6 on days 15 and 30, in IL-8 on day 30, and in TNF-α and INF-γ on day 15, as well as an increase in IL-1ra on days 3 and 15 and in IL-10 on day 30. Oropharyngeal mother's milk administration for 15 days decreases the pro-inflammatory state of preterm neonates and provides full enteral nutrition earlier, which could have a positive influence on the development of the immune system and inflammatory response, thereby positively influencing other developmental outcomes.

Enhancement of immune response mediated by oropharyngeal colostrum administration in preterm neonates.

BACKGROUND: The immune system of preterm infants is immature, being a significant cause of morbidity and mortality, particularly in the preterm infant. Oropharyngeal colostrum administration could be an immunomodulatory aid. Our aim was to evaluate the effect of oropharyngeal colostrum on the serum levels of immunoglobulins, lactoferrin, and resistin during the first month of life and to track the clinical outcome of the neonates. METHODS: One hundred preterm neonates born at <32 weeks of gestation and/or weighing < 1500 g and assisted in the Neonatal Intensive Care Unit were enrolled and divided into two groups: colostrum (n = 48) and control (n = 52). The subjects assigned to the colostrum group received 0.2 mL of colostrum (oropharyngeal route) every 4 hours for the first 15 days of life, and if mothers have inability to breastfeed, they were included in the control group (no oropharyngeal colostrum). Serum concentrations of IgA, IgM, and IgG1, lactoferrin, and resistin were assessed in both groups at 1, 3, 15, and 30 days of life. Clinical data during hospitalization were collected. RESULTS: IgA and IgM increased in preterm neonates who were administered colostrum for 15 and 30 days. Lactoferrin increased after 30 days, and resistin increased after 15 days of supplying oropharyngeal colostrum. The colostrum group underwent full enteral nutrition before, and no differences were observed in the common neonatal morbidities. CONCLUSION: Oropharyngeal colostrum administration is safe in preterm neonates and improves their immunologic profile, showing a potential role as an immunomodulatory agent.

Cognitive Functioning and Academic Achievement in Children Aged 6-8 Years, Born at Term After Intrauterine Growth Restriction and Fetal Cerebral Redistribution.

Objective: To determine whether cerebroplacental ratio, an indicator of fetal cerebral redistribution (FCR), predicts adverse results for neurodevelopment in intrauterine growth restriction (IUGR) infants. Methods: In a cohort of 5,702 infants, 64 were IUGR born at term with FCR. Five were excluded. Of the remainder, 32 presented an abnormal cerebroplacental ratio (IUGR-A) and 27 a normal one (IUGR-B). The controls were 61 appropriate-for-gestational-age children. Cognitive and academic outcomes and the odds ratio of lower academic scores were assessed by multivariate analysis of covariance and logistic regression. Results: IUGR-A children presented deficits in cognitive functioning and academic achievement in all domains. IUGR-B children presented slight deficits. Suboptimal cognitive functioning in IUGR-A was more marked in working memory. Abnormal cerebroplacental ratio predicted low academic scores in IUGR-A. Conclusions: FCR is a risk factor for IUGR infants, and cerebroplacental ratio identifies those most severely affected. Intervention programs may produce benefits in early-middle childhood.

Efectos de la administración de calostro orofaríngeo en recién nacidos prematuros sobre los niveles de inmunoglobulina A.

Introducción: el recién nacido prematuro de muy bajo peso (RNMBP) es inmunológicamente inmaduro y además presenta una alteración de las barreras naturales de defensa. Objetivo: evaluar los efectos que pueda tener la administración de calostro orofaríngeo, administrado durante los primeros 15 días posnatales, sobre los niveles de inmunoglobulina A (IgA) sérica en recién nacidos prematuros de muy bajo peso durante el primer mes de vida. Material y métodos: se desarrolló un estudio de intervención no aleatorizado con grupo control, en el que se incluyeron 38 recién nacidos con ≤ 32 + 6 semanas de gestación y/o menores de 1.500 g de peso. Los sujetos recibieron 0,2 ml de calostro de su madre cada 4 h, iniciándose el procedimiento en las primeras 24 h de vida hasta el 15.o día postnatal. Se midieron los niveles de IgA en la sangre al nacimiento, 3. er , 15.o y 30.o días de vida. Se registraron datos perinatales al nacimiento y durante el periodo de seguimiento. Resultados: IgA sérica aumentó de forma estadísticamente significativa en el grupo de intervención (M1 15,84 µg/ml, M2 20,07 µg/ml, M3 23,65 µg/ml, M4 30,34 µg/ml, p 0,001) y en el grupo control (M1 12,48 µg/ml, M2 16,48 µg/ml, p 0,018; M3 19,41 µg/ml, M4 22,48 µg/ml, p 0,001). Al mes de vida, los niveles de IgA sérica fueron significativamente mayores en el grupo de intervención que en el grupo control (p 0,026). Conclusiones: este estudio sugiere que la administración de calostro orofarínge.

Introduction: Very low birth weight (VLBW) newborns have an immature immune system and also disrupted defense natural barriers. Objective: To evaluate the immunologic effects of oropharyngeal colostrum administration to VLBW infants in their first two weeks of life, by assessing IgA serum levels evolution up to one month of life. Material and methods: We conducted an interventional, no randomized, controlled trial recruiting 38 newborns under ≤ 32 + 6 gestational weeks and/or under 1,500 g at birth. Subjects received 0,2 ml of their mother colostrum every 4 hours, starting in the first 24 hours of life, and for a 15 days period. IgA serum levels were measured at birth, 3, 15 and 30 days of life. Perinatal data for the first month of life were registered. Results: Along the first month of life an increase in IgA levels was found in colostrum group (M1 15.84 µg/ml, M2 20.07 µg/ml, M3 23.65 µg ml, M4 30.34 µg/ml, p 0.001) and in control group (M1 12.48 µg/ml, M2 16.48 µg/ml, p 0.018; M3 19.41 µg/ml, M4 22.48 µg/ml, p 0.001). IgA serum levels were statistically increased in colostrum group, in respect to control group at one month of age (p 0.026). Conclusions: Our data suggest that oropharyngeal colostrum administration might facilitate the development of immune system in VLWB infants at one month of age, by increasing IgA serum levels (AU)
