Despite these advantages, experience with ABE differs significantly, often leading to anxiety over perceived inadequate milk supply and eventual breastfeeding cessation. This study comprehensively evaluates the knowledge, attitudes, and real-world experiences of individuals with gestational or pregestational diabetes concerning ABE, with a focus on total milk volume expressed prior to birth.</p><p><strong>Study design: </strong> Utilizing a convenience sampling method, we surveyed individuals with gestational or pregestational diabetes from three health care facilities who were trained in ABE. Knowledge and perceptions were gauged through presurvey statements, while postsurvey statements were employed to measure experiences, both using a 5-point Likert scale. In parallel, a retrospective study assessed both maternal and infant outcomes among the same participant pool.

Both groups were demographically similar and showed comparable newborn outcomes.

The objective of this study is to evaluate the effectiveness of a type of bassinet in the treatment of infants with neonatal abstinence syndrome.</p><p><strong>Study design: </strong> This is a retrospective observational cohort study. Study setting involved a 24-bed open-bay Level III neonatal intensive care unit located in a metropolitan academic trauma facility. Participant inclusion criteria involved prenatally opioid-exposed infants ≥ 35 weeks with confirmed maternal opioid urine toxicology, required pharmacological treatment for withdrawal symptoms, and were admitted to the neonatal intensive care unit. Three subsets of study participants were analyzed over three different time periods: Group 1 were infants admitted during 2019 without nonpharmacological intervention, Group 2 who were admitted from September 2021 to February 2022 and received nonpharmacological interventions, and Group 3 included those admitted from February 2022 to March 2023 who received the same interventions as Group 2 but were managed in bassinets being used in other local facilities for neonatal abstinence syndrome.</p><p><strong>Results: </strong> Group 3 had significant increases in length of stay compared with Group 1 (<i>p</i> = 0.006) and Group 2 (<i>p</i> = 0.013).
