Ethical Issues in Umbilical Cord Blood Banking

, 1997
OBJECTIVE: Banking umbilical cord blood (UCB) to be used as a source of stem cells for transplantation is associated with a set of ethical issues. An examination of these issues is needed to inform public policy and to raise the awareness of prospective ...

Umbilical cord vessels other than the umbilical arteries and vein: a histological study of midterm human fetuses

, 2022
At birth, the umbilical cord contains various types of thin vessels that are near and outside the umbilicus and separate from the umbilical arteries and vein.

Exploring hemodynamic alterations in gastroschisis: insights into fetal growth restriction using prenatal MRI

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 795-805, June 2026.
Abstract Objective Despite the high incidence of fetal growth restriction (FGR) in gastroschisis (GS) associated with placental fetal vascular malperfusion (FVM), the underlying mechanism remains unclear. We aimed to investigate whether umbilical vein (UV) stenosis at the abdominal wall defect impairs fetoplacental circulation, leading to FGR.

Identification of fifty-seven novel loci for abdominal wall hernia development and their biological and clinical implications: results from the UK Biobank

, 2022
Purpose: Familial aggregation is known for both hernia development and recurrence. To date, only one genome-wide association study (GWAS) limited to inguinal hernia has been reported that identified four risk-associated loci.

Physiological‐Based Cord Clamping and Early Oxygenation in Newborns With Transposition of the Great Arteries: A Quality Improvement Study Protocol

CJC Pediatric &Congenital Heart Disease, Volume 5, Issue 3, Page 136-144, June 2026.
Central Illustration Abstract At birth, major circulatory and pulmonary adaptations are required for a successful foetal‐to‐neonatal transition. In newborns with transposition of the great arteries (TGA), this transition is often impaired, leading to severe hypoxemia.

How Epigenetics Bridges Genes and Environment: A Multiomics Evidence Chain in Congenital Diaphragmatic Hernia

Birth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background/Objectives Congenital diaphragmatic hernia (CDH) is a severe developmental anomaly with high etiological heterogeneity. Although numerous susceptibility genes have been identified, genetic factors alone fail to explain the full disease risk. Epidemiological data highlight the contribution of environmental exposures.

The Expanding Role of Gene Sequencing in Shaping Fetal Therapies: Clinical and Ethical Considerations

Prenatal Diagnosis, Volume 46, Issue 5-6, Page 623-635, May 2026.
ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and
