RESUMEN
BACKGROUND: Maternal worry about infant weight has inconsistently been reported as a breastfeeding barrier. Weight monitoring is a critical tool to assess adequacy of infant feeding. Yet, little is known about the intensity of maternal worry about infant weight or associated breastfeeding outcomes. RESEARCH AIMS: To examine (1) the frequency and intensity of maternal worry about infant weight; (2) the relationship between worry about weight and use of artificial milk; and 3) the relationship between worry about weight and breastfeeding cessation. METHODS: A prospective cross-sectional design was used. A questionnaire was completed by women in the United States (N = 287) from 12 web-based maternal support groups. RESULTS: Sixty-three percent of women (n = 182) had some worry about infant weight. Participants breastfeeding for the first time had more worry (p = .035). Participants still breastfeeding had less worry about weight compared to those who had stopped (67%, n = 147 vs. 41%, n = 28). Exclusive breastfeeding participants had less worry (p < .001) compared to those who supplemented with artificial milk. Increased worry was associated with the use of artificial milk within 1 week of birth (p < .001) and early breastfeeding cessation (p < .001). CONCLUSIONS: Worry about weight is a significant breastfeeding barrier. It is associated with first time breastfeeding, less exclusive breastfeeding, use of artificial milk, and earlier breastfeeding cessation. Lactating mothers need anticipatory guidance about expected neonatal weight changes and interventions to help relieve worry about infant weight.

OBJECTIVE: This study aimed to determine if delayed cord clamping (DCC) affected brain myelin water volume fraction (VFm) and neurodevelopment in term infants. STUDY DESIGN: This was a single-blinded randomized controlled trial of healthy pregnant women with term singleton fetuses randomized at birth to either immediate cord clamping (ICC) (≤ 20 seconds) or DCC (≥ 5 minutes). Follow-up at 12 months of age consisted of blood work for serum iron indices and lead levels, a nonsedated magnetic resonance imaging (MRI), followed within the week by neurodevelopmental testing. RESULTS: At birth, 73 women were randomized into one of two groups: ICC (the usual practice) or DCC (the intervention). At 12 months, among 58 active participants, 41 (80%) had usable MRIs. There were no differences between the two groups on maternal or infant demographic variables. At 12 months, infants who had DCC had increased white matter brain growth in regions localized within the right and left internal capsules, the right parietal, occipital, and prefrontal cortex. Gender exerted no difference on any variables. Developmental testing (Mullen Scales of Early Learning, nonverbal, and verbal composite scores) was not significantly different between the two groups. CONCLUSION: At 12 months of age, infants who received DCC had greater myelin content in important brain regions involved in motor function, visual/spatial, and sensory processing. A placental transfusion at birth appeared to increase myelin content in the early developing brain. KEY POINTS: · DCC resulted in higher hematocrits in newborn period.. · DCC appears to increase myelin at 12 months.. · Gender did not influence study outcomes..

Placental transfusion results in a significant decrease in the risk of death for extremely preterm infants. With immediate cord clamping (ICC), these infants can leave up to one-half of their normal circulating in utero blood volume in the placenta. Extremely preterm infants are at highest risk of harm from ICC yet are currently the most likely to receive ICC. Receiving a placenta transfusion provides infants with life-saving components and enhanced perfusion. We present some lesser-known but important effects of placental transfusion. New research reveals that enhanced vascular perfusion causes an organ's endothelial cells to release angiocrine responses to guide essential functions. High progesterone levels and pulmonary artery pressure in the first few hours of life assist with neonatal adaptation. We propose that lack of essential blood volume may be a major factor contributing to inflammation, morbidities, and mortality that preterm infants frequently encounter.

OBJECTIVE: The aim of this study was to estimate the incidence and identify the factors associated with neonatal readmission among healthy term infants. STUDY DESIGN: A nested case-control study with matching was conducted at a large level III perinatal hospital with approximately 8,700 deliveries each year. Each case infant (n = 130) was matched to two control infants (n = 260) on the case infant's date of birth (±7 days) and the mother's maternal age (<20 years, 20-29, 30-39, and >39 years). All infants were selected from a cohort of eligible term, healthy, in-state infants admitted to the newborn unit postdelivery from January 1, 2016 to May 8, 2017. Data were analyzed using hierarchical conditional logistic regression. RESULTS: The incidence of neonatal readmission was 2.2%, and all readmissions occurred within 8.6 days of birth. Earlier gestational age (37 weeks; odds ratio [OR]: 4.11, 95% confidence interval [CI]: 1.79-9.45; 38 weeks OR: 1.29, CI 0.60-2.75; [ref] 39 weeks), jaundice on day two of life (OR: 2.45; CI: 1.40-4.30), maternal group B streptococcus chemoprophylaxis (OR: 2.55; CI: 1.23-5.28 [Ref N/A]) were associated with readmission. Delivery by cesarean section (OR: 0.31, CI: 0.12-0.79) and each milliliter of formula [first three days] (OR: 0.96; CI: 0.993-0.999) were protective. CONCLUSION: Neonatal readmission in healthy term infants may potentially be reduced with identification of modifiable determinants of readmission prior to discharge. Policies to capture the true incidence of neonatal readmissions should include admissions to hospitals other than the birth hospital.

OBJECTIVE: To evaluate whether placental transfusion influences brain myelination at 4 months of age. STUDY DESIGN: A partially blinded, randomized controlled trial was conducted at a level III maternity hospital in the US. Seventy-three healthy term pregnant women and their singleton fetuses were randomized to either delayed umbilical cord clamping (DCC, >5 minutes) or immediate clamping (ICC, <20 seconds). At 4 months of age, blood was drawn for ferritin levels. Neurodevelopmental testing (Mullen Scales of Early Learning) was administered, and brain myelin content was measured with magnetic resonance imaging. Correlations between myelin content and ferritin levels and group-wise DCC vs ICC brain myelin content were completed. RESULTS: In the DCC and ICC groups, clamping time was 172 ± 188 seconds vs 28 ± 76 seconds (P < .002), respectively; the 48-hour hematocrit was 57.6% vs 53.1% (P < .01). At 4 months, infants with DCC had significantly greater ferritin levels (96.4 vs 65.3 ng/dL, P = .03). There was a positive relationship between ferritin and myelin content. Infants randomized to the DCC group had greater myelin content in the internal capsule and other early maturing brain regions associated with motor, visual, and sensory processing/function. No differences were seen between groups in the Mullen testing. CONCLUSION: At 4 months, infants born at term receiving DCC had greater ferritin levels and increased brain myelin in areas important for early life functional development. Endowment of iron-rich red blood cells obtained through DCC may offer a longitudinal advantage for early white matter development. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01620008.

OBJECTIVE: To assess the effect of delayed cord clamping (DCC) vs immediate cord clamping (ICC) on intraventricular hemorrhage (IVH), late onset sepsis (LOS), and 18-month motor outcomes in preterm infants. STUDY DESIGN: Women (n = 208) in labor with singleton fetuses (<32 weeks gestation) were randomized to either DCC (30-45 seconds) or ICC (<10 seconds). The primary outcomes were IVH, LOS, and motor outcomes at 18-22 months corrected age. Intention-to-treat was used for primary analyses. RESULTS: Cord clamping time was 32 ± 16 (DCC) vs 6.6 ± 6 (ICC) seconds. Infants in the DCC and ICC groups weighed 1203 ± 352 and 1136 ± 350 g and mean gestational age was 28.3 ± 2 and 28.4 ± 2 weeks, respectively. There were no differences in rates of IVH or LOS between groups. At 18-22 months, DCC was protective against motor scores below 85 on the Bayley Scales of Infant Development, Third Edition (OR 0.32, 95% CI 0.10-0.90, P = .03). There were more women with preeclampsia in the ICC group (37% vs 22%, P = .02) and more women in the DCC group with premature rupture of membranes/preterm labor (54% vs 75%, P = .002). Preeclampsia halved the risk of IVH (OR 0.50, 95% CI 0.2-1.0) and premature rupture of membranes/preterm labor doubled the risk of IVH (OR 2.0, 95% CI 1.2-4.3). CONCLUSIONS: Although DCC did not alter the incidence of IVH or LOS in preterm infants, it improved motor function at 18-22 months corrected age. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov: NCT00818220 and NCT01426698.

A newborn who receives a placental transfusion at birth, either from cord milking or delayed cord clamping, obtains about 30% more blood volume than the newborn whose cord is cut immediately. Receiving an adequate blood volume from placental transfusion at birth may be protective for the distressed neonate as it prevents hypovolemia and can support optimal perfusion to all organs. New research shows that ventilating before clamping the umbilical cord can reduce large swings in cardiovascular function and help to stabilize the newborn. Hypovolemia, often associated with nuchal cord or shoulder dystocia, may lead to an inflammatory cascade and subsequent ischemic injury. A sudden unexpected neonatal asystole at birth may occur from severe hypovolemia. The restoration of blood volume is an important action to protect the hearts and brains of these neonates. Current protocols for resuscitation imply immediate cord clamping and the care of the newborn away from the mother's bedside. We suggest that an intrapartum care provider can achieve placental transfusion for the distressed neonate by milking the cord several times or resuscitating the neonate at the perineum with an intact cord. Milking the cord can be done quickly within the current Neonatal Resuscitation Program guidelines. Cord blood gases can be collected with delayed cord clamping. Bringing the resuscitation to the mother's bedside is a novel concept and supports an intact cord. Adopting a policy for resuscitation with an intact cord in a hospital setting will take concentrated effort and team work by obstetrics, pediatrics, midwifery, and nursing.

A brief delay in clamping the umbilical cord results in a placental transfusion that supplies the infant with a major source of iron during the first few months of life. Cord circulation continues for several minutes after birth and placental transfusion results in approximately 30% more blood volume. Gravity influences the amount of placental transfusion that an infant receives. Placing the infant skin-to-skin requires a longer delay of cord clamping (DCC) than current recommendations. Uterotonics are not contraindicated with DCC. Cord milking is a safe alternative to DCC when one must cut the cord prematurely. Recent randomized controlled trials demonstrate benefits for term and preterm infants from DCC. The belief that DCC causes hyperbilirubinemia or symptomatic polycythemia is unsupported by the available research. Delay of cord clamping substantively increases iron stores in early infancy. Inadequate iron stores in infancy may have an irreversible impact on the developing brain despite oral iron supplementation. Iron deficiency in infancy can lead to neurologic issues in older children including poor school performance, decreased cognitive abilities, and behavioral problems. The management of the umbilical cord in complex situations is inconsistent between birth settings. A change in practice requires collaboration between all types of providers who attend births.

It is estimated that 6-10% of women are pregnant when they enter the prison system. The majority have had little, if any, prenatal care and/or childbirth education. Given economic constraints, the educational and support needs of this population are often not met. In response to these needs, an educational/support group was developed and led by a social worker, a mental health clinical nurse specialist, and a nurse midwife in a women's correctional facility in the Northeast. Women in various stages of pregnancy and early postpartum voluntarily attended. The need for education and psychosocial support was overwhelming. This group fostered a safe space for women to discuss real-life issues in a supportive environment. Meeting the educational and support needs of incarcerated women is paramount.

Many common care practices during labor, birth, and the immediate postpartum period impact the fetal to neonatal transition, including medication used during labor, suctioning protocols, strategies to prevent heat loss, umbilical cord clamping, and use of 100% oxygen for resuscitation. Many of the care practices used to assess and manage a newborn immediately after birth have not proven efficacious. No definitive outcomes have been obtained from studies on maternal analgesia effects on the newborn. Although immediate cord clamping is common practice, recent evidence from large randomized, controlled trials suggests that delayed cord clamping may protect the infant against anemia. Skin-to-skin care of the newborn after birth is recommended as the mainstay of newborn thermoregulation and care. Routine suctioning of infants at birth was not been found to be beneficial. Neither amnioinfusion, suctioning of meconium-stained babies after the birth of the head, nor intubation and suctioning of vigorous infants prevents meconium aspiration syndrome. The use of 100% oxygen at birth to resuscitate a newborn causes increased oxidative stress and does not appear to offer benefits over room air. This review of evidence on newborn care practices reveals that more often than not, less intervention is better. The recommendations support a gentle, physiologic birth and family-centered care of the newborn.
