Diffuse correlation spectroscopy blood flow monitoring for intraventricular hemorrhage vulnerability in extremely low gestational age newborns.

In premature infants with an extremely low gestational age (ELGA, < 29 weeks GA), dysregulated changes in cerebral blood flow (CBF) are among the major pathogenic factors leading to germinal matrix/intraventricular hemorrhage (GM/IVH). Continuous monitoring of CBF can guide interventions to minimize the risk of brain injury, but there are no clinically standard techniques or tools for its measurement. We report the feasibility of the continuous monitoring of CBF, including measures of autoregulation, via diffuse correlation spectroscopy (DCS) in ELGA infants using CBF variability and correlation with scalp blood flow (SBF, served as a surrogate measure of systemic perturbations).

Association of early cerebral oxygen saturation and brain injury in extremely preterm infants.

Objective: To assess the association between cerebral saturation (crSO) using Near-Infrared Spectroscopy (NIRS) and brain injury in extremely preterm infants.

Study Design: This retrospective study includes 62 infants (<28 weeks gestation) who underwent continuous NIRS monitoring in the first 5 days after birth. Median crSO were compared in 12 h increments between infants with and without germinal matrix/intraventricular hemorrhage (GM/IVH).

The Effects of COVID-19 Hospital Practices on Breastfeeding Initiation and Duration Postdischarge.

Early in the COVID-19 pandemic, many birth hospitals separated SARS-CoV-2-positive mothers from their newborn infants and advised against breastfeeding to decrease postnatal SARS-CoV-2 transmission. Information on how these practices impacted breastfeeding postdischarge is limited. In a statewide sample of SARS-CoV-2-positive mothers, we aimed to determine the extent to which (1) mother-infant separation and (2) a lack of breastfeeding initiation in-hospital were associated with breast milk feeding postdischarge.

Targeting human milk fortification to improve very preterm infant growth and brain development: study protocol for Nourish, a single-center randomized, controlled clinical trial.

Background: Human milk is recommended for very preterm infants, but its variable macronutrient content may contribute to undernutrition during a critical period in development. We hypothesize that individually targeted human milk fortification is more effective in meeting macronutrient requirements than the current standard of care.

Methods: We designed a single-center randomized, controlled trial enrolling 130 infants born < 31 completed weeks' gestation.

Macronutrient Intake from Human Milk, Infant Growth, and Body Composition at Term Equivalent Age: A Longitudinal Study of Hospitalized Very Preterm Infants.

The variable macronutrient content of human milk may contribute to growth deficits among preterm infants in the neonatal intensive care unit (NICU). In a longitudinal study of 37 infants < 32 weeks gestation, we aimed to (1) determine the between-infant variation in macronutrient intake from human milk and (2) examine associations of macronutrient intake with growth outcomes. We analyzed 1626 human milk samples (median, 43 samples/infant) with mid infrared spectroscopy.

Nutritional and immunological considerations relevant to infant nutrition.

Optimal nutrition during infancy is critical not only to support the dramatic growth and development that takes place during the first 12 months following birth but also for establishing a healthy immune response throughout childhood and across the life span. The normative standards for infant feeding and nutrition are breast-feeding and human breast milk. However, in cases in which human breast milk is not available, infant formula is substituted.
