The use of human placenta as a matrix for the prediction of the baby's sex has been recently documented, but evaluation methods for placental sex-determining genes allowing reliable sex prediction are still lacking. We compared the accuracy of the retrospective prediction of the baby's sex using placental mRNA expression of RPS4Y1, DDX3Y, and XIST analyzed by an already reported method and a newly developed evaluation approach. Full concordance between the predicted and the actual baby sex was only obtained when analyzing placental RPS4Y1 expression with the newly proposed method, which was found to be robust and reliable.

Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.

Objectives: To assess whether exposure to an infant safe sleep initiative was associated with maternal report of infant safe sleep practice at home and to identify other predictive factors.
Methods: After linking Pennsylvania data on infant safe sleep initiative implementation at 27 hospitals to birth certificate and Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2017 to 2021, we generated descriptive statistics to compare infant safe sleep practice and other characteristics between respondents exposed to the initiative and all other PRAMS respondents with a hospital birth. Using multivariable logistic regression, we modeled the association between exposure to the initiative and maternal self-report of placing their infant to sleep on their back, on a separate surface, without soft objects, or room sharing without bed sharing.

Breast milk is essential for infant health, but the transfer of xenobiotic chemicals poses significant risks. Ethical challenges in clinical trials necessitate the use of in vitro predictive models to assess chemical exposure risks in breastfeeding infants. This study introduces an explainable machine learning model to predict the risk of chemical transfer through human milk.

Purpose: To enhance the detection rate of Neonatal Intrahepatic Cholestasis caused by Citrin Deficiency (NICCD) through newborn screening (NBS), we analyzed the metabolic profiles of missed patients and proposed a more reliable method for early diagnosis.
Methods: In this retrospective study, NICCD patients were classified into "Newborn Screening" (64 individuals) and "Missed Screening" (52 individuals) groups. Metabolic profiles were analyzed using the non-derivatized MS/MS Kit, and genetic mutations were identified via next-generation sequencing and confirmed by Sanger sequencing.

Background: Consequences of lung injury and inflammation in preterm infants with bronchopulmonary dysplasia (BPD) contribute to prolonged oxygen requirements. Home oxygen therapy (HOT) is an alternative way of respiratory support in infant with BPD. However, there is no consensus on weaning guidelines.
