background and aim: horseshoe placenta is a variant of ring-shaped placenta. ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. this report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

Infection is considered a possible trigger for preterm labour, supported by evidence showing the presence of bacteria in the placenta and placental membranes from preterm births. In this study, 16S rDNA pyrosequencing was used to identify bacteria in placental membranes. Caesarean sections and vaginal deliveries at term were found to harbour common genera. Mycoplasma hominis, Aerococcus christe...

Background & Objective: It was declared that COVID-19 might be more severe in symptomatic pregnant patients. This study conducted to examine the pathological indices of placenta women who were diagnosed with COVID-19.Methods: A total 20 COVID-19–positive mothers enrolled this study. Detailed placental pathology findings compared between subjects based on history abortion or occurrence preterm d...

To investigate labour-associated changes in production of activin and related hormones by gestational tissues we prepared extracts from amnion, choriodecidual and placental tissues delivered at term before labour (TNL; n=15), at term after spontaneous labour (TSL; n=15) or preterm (PTD; n=31) and measured concentrations of inhibin A, activin A and follistatin by ELISA. Activin concentrations in...

Prostaglandins, pro-inflammatory cytokines, extracellular matrix remodelling enzymes and nuclear factor-kappa B (NF-κB) are involved in the mechanisms of term and preterm parturition. Recent studies have reported an increase in angiogenesis-related genes during term and preterm labour, including placental growth factor (PLGF). In non-gestational tissues, PLGF induces inflammation via NF-κB. The...

Preterm birth is a major public health problem in terms of loss of life, long-term and short term disabilities worldwide. The process of parturition (both term and preterm) involves intensive remodelling of the extracellular matrix (ECM) in the placenta and fetal membranes by matrix metalloproteinases (MMPs). Our previous studies show reduced docosahexaenoic acid (DHA) in women delivering prete...

BACKGROUND The electrical activity of the uterine muscle is representative of uterine contractility. Its characterization may be used to detect a potential risk of preterm delivery in women, even at an early gestational stage. METHODS We have investigated the effect of the recording electrode position on the spectral content of the signal by using a mathematical model of the women's abdomen. ...

We report a case of uterine dehiscence during pregnancy. Uterine dehiscence and rupture are serious complications of pregnancy. This situation takes place especially in women that prior uterine operation(s). We represent a 30-year-old woman diagnosed uterine dehiscence at 22 gestation week. Uterine dehiscence treated surgically and then medical treatment was given to prevent preterm labour. At ...

The retained placenta is a significant cause of maternal mortality and morbidity throughout the developing world. It complicates 2% of all deliveries and has a case mortality rate of nearly 10% in rural areas. Ultrasound studies have provided fresh insights into the mechanism of the third stage of labour and the aetiology of the retained placenta. Following delivery of the baby, the retro-place...
