Histomorphometric Analysis of Umbilical Cord Blood Vessel Thickness amongst Normal and Intrauterine Growth-restricted Newborns

Advances in Human Biology
Introduction: The umbilical cord (UC), comprising one vein and two arteries embedded in Wharton’s jelly, is critical for foetal-maternal exchange. Structural alterations in the UC have been associated with adverse foetal outcomes such as intrauterine ...

Computer Model Predicting the Ideal Pitch of the Coiling Umbilical Arteries

, 2016
: A fetus physiologically relies on blood for nutrients given by the mother. Blood supply is provided to a fetus through an umbilical cord having the structure of two pulsatile arteries with smooth muscle surrounding a thin walled vein.

Umbilical Cord Coiling

, 2019
The umbilical cord has a characteristic coiling pattern with both arteries coiling around the umbilical vein. This architecture is intrinsic to the cord and cannot be undone by unwinding in the opposite direction, unlike torsion.

Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

A comparison in maternal and neonatal outcomes between mild fundal pressure and vacuum extraction for shortening the second stage of labor

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Mild fundal pressure (MFP) and vacuum extraction (VE) are interventions used during the second stage of labor when clinical intervention is required. While VE is well established with standardized training and predictable risks, MFP remains controversial with limited comparative data. This study aimed to compare maternal and neonatal

Fetal autonomic responses inferred from heart rate variability during recurrent decelerations without acidosis—An observational study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Recurrent fetal heart rate (FHR) decelerations without acidosis are frequently observed during labor; however, the underlying autonomic mechanisms remain incompletely understood. This study explored fetal autonomic responses to recurrent decelerations using FHR and FHR variability (FHRV) parameters.
