Neonatal Outcomes since the Implementation of No Routine Endotracheal Suctioning of Meconium-Stained Nonvigorous Neonates.

Objective: This study aimed to evaluate the effect of the 2015 Neonatal Resuscitation Program recommendations of no routine endotracheal suctioning for nonvigorous neonates on the incidence of meconium aspiration syndrome (MAS) and death. We hypothesized that the revised guidelines have not changed the outcome of MAS/death.

Study Design: This was a single-center retrospective cohort study.

Risk Factors Associated With COVID-19 Symptoms and Potential Vertical Transmission During Pregnancy: A Retrospective Cohort Study.

Objective The COVID-19 pandemic is of special concern for pregnant women. A growing body of evidence suggests the virus can have a deleterious impact upon outcomes related to birth and newborn health. There is a paucity of published research demonstrating the factors that influence disease severity among those who are pregnant, while a growing body of evidence demonstrates that vertical transmission occurs.

Vitamin D status in very low birth weight infants and response to vitamin D intake during their NICU stays: a prospective cohort study.

Objective: To evaluate vitamin D status in very low birth weight (VLBW) infants and response to vitamin D intake.

Study Design: In this prospective cohort study of VLBW infants, 25-hydroxyvitamin D [25(OH)D] was measured regularly starting at birth. Daily vitamin D intake was estimated from parenteral and enteral sources.

Adrenocorticotropic hormone and cortisol levels in term infants born with meconium-stained amniotic fluid.

Objective: To evaluate cord blood concentrations of adrenocorticotropic hormone (ACTH) and cortisol in well term infants born with and without meconium-stained amniotic fluid (MSAF) and term infants born with MSAF who experienced respiratory distress (RD).

Study Design: This was a prospective observational study. Fifty-four term infants were enrolled in the study in three groups: group 1 consisted of 18 well infants who were born with clear amniotic fluid, group 2 had 18 well infants born with MSAF, and group 3 had 18 infants born with MSAF who experienced RD in the first 24 h of age.
