Aniridia is an autosomal dominant congenital malformation associated with mutations in the PAX6 gene. It can be associated with deletion in the contiguous WT1 gene, leading to WAGR syndrome, characterized by Wilm tumor, aniridia, genitourinary anomalies, and mental retardation. Persistent fetal vasculature is a developmental malformation caused by incomplete regression of hyaloid vasculature. Most cases of persistent fetal vasculature occur sporadically; however, some inherited forms are described. We report a case of genetically confirmed WAGR associated with congenital cataract and persistent fetal vasculature.

Acute maternal hyperoxygenation to predict hypoxia and need for emergency intervention in fetuses with transposition of the great arteries: a pilot study.

Background: Newborns with transposition of the great arteries (TGA) are at risk of severe hypoxia from inadequate atrial mixing, closure of the arterial duct and/or pulmonary hypertension (PPHN). Acute maternal hyperoxygenation (AMH) might assist in identifying at-risk fetuses. We report pulmonary vasoreactivity to AMH in TGA fetuses and its relationship to early postnatal hypoxia and requirement for emergency balloon atrial septostomy (e-BAS).

Introduction: The urachus is a fetal canal that connects the allantois to the bladder and typically obliterates by the 6th month of gestation. Failure of the urachus to obliterate can result in urachal anomalies, which, in rare cases, may undergo malignant transformation.
Case Presentation: We present a case of a 13-year-old female who experienced hematuria, dysuria, and abdominal pain persisting for over 4 months.
Antiphospholipid syndrome is an autoimmune disease characterised by thrombotic and/or obstetric manifestations with persistent antiphospholipid antibodies. Diagnosis involves confirming the persistence of antiphospholipid antibodies in symptomatic patients, using validated classification criteria as a guide. The likelihood of obtaining false-positive or false-negative test results in certain settings, and the lack of standardisation between laboratory methods, are important considerations.

Background: Following maternal COVID-19 vaccination, the persistence of antibodies in sera and breast milk for mothers and infants is not well characterized. We sought to describe the persistence of antibodies through 2 months after delivery in maternal and infant serum and breast milk following maternal COVID-19 mRNA vaccination and to examine differences by receipt of booster dose during pregnancy or postpartum.
Methods: This is a prospective cohort study with enrollment from July 2021 to January 2022 at 9 US academic sites.

Background: Inflammatory bowel disease (IBD) is a persistent inflammation of the digestive system, and Mesenchymal Stem Cells (MSCs) and their exosomes have demonstrated potential as treatments for this condition. The objective of this research was to examine the possible effectiveness of intraperitoneal injection of umbilical cord-MSCs (UC-MSCs) and their exosomes through a two-time injection regimen in a mouse model.
Method: In this study, an animal model of a specific type of IBD in C57BL/6 mice, induced by dextran sulfate sodium (DSS), was utilized.
