Association of BNT162b2 SARS-CoV-2 vaccination during pregnancy with postnatal outcomes in premature infants.

Aim: The effect of COVID-19 vaccine given during pregnancy on premature infants is unknown. This study aims to determine the association between maternal COVID-19 vaccine with postnatal outcome in premature infants.

Methods: This is a single-centre retrospective case-control study of infants born before 35 weeks gestation to mothers who received SARS-CoV-2 vaccine during pregnancy compared with infant born to non-vaccinated mothers.

"I'll Be There": Informal and Formal Support Systems and Mothers' Psychological Distress during NICU Hospitalization.

Mothers of infants hospitalized in the Neonatal Intensive Care Unit (NICU) are at a high risk for psychological distress, which is of concern to health and social professionals due to the negative implications for mothers and infants. A model for explaining maternal psychological distress, consisting of intolerance to uncertainty and support from informal (spouse, family, and friends) and formal (medical staff) systems was examined. Data was collected from one of the largest NICUs in Israel; 129 mothers of 215 preterm infants completed self-report questionnaires regarding their background variables, intolerance to uncertainty, perceived informal support and perceived medical staff support.

The Clinical Significance of Extreme Leukocytosis among Newborns: A Retrospective Cohort Study.

Objective: The aim of the study is to examine the clinical significance of extreme leukocytosis (>40,000 cells/µL) at birth among neonates.

Study Design: Data were retrospectively collected on 208 infants with leukocytosis >40,000 cells/µL and on matched normal controls as determined in complete blood counts obtained on the first day of life.

Results: There were no significant group differences in birth weight, Apgar's score, timing of respiratory support, hospitalization in special care units or rehospitalization during the first month of life.

Exposure to War Prior to Conception: Maternal Emotional Distress Forecasts Sex-Specific Child Behavior Problems.

Objectives: Exposure to maternal stress during the prenatal period adversely affects child outcomes. Recent investigations have shifted to an even earlier period, the preconception period, to better understand the role of this formative period in human health and disease. We investigated the links between maternal emotional distress following preconception exposure to war, and child outcomes at age 10.

Determinants of Staphylococcus aureus carriage in the developing infant nasal microbiome.

Background: Staphylococcus aureus is a leading cause of healthcare- and community-associated infections and can be difficult to treat due to antimicrobial resistance. About 30% of individuals carry S. aureus asymptomatically in their nares, a risk factor for later infection, and interactions with other species in the nasal microbiome likely modulate its carriage.
