Article Abstract
Purpose: To estimate the prevalence of recurrent miscarriage (RM) and investigate the association between RM and adverse maternal outcomes in subsequent pregnancies.
Participants And Methods: This is an interim analysis of a prospective study of 1737 pregnant women with gravidity of two or more prior to the current pregnancy. These women joined the Mutaba'ah Study between May 2017 and April 2019 and were followed up until they delivered. Hospital medical records were used to extract data on past pregnancy history and the progress and outcomes of the current pregnancy, such as gestational diabetes, preeclampsia, mode of delivery, preterm delivery, and complications at birth.
Results: Amongst pregnant women with at least two previous pregnancies (n=1737), there were 234 (13.5%) women with a history of two or more consecutive miscarriages. Women with RM were slightly older, more parous, and more likely to have had previous infertility treatment (all p-values <0.05). Women with a history of RM had independently significant increased odds of cesarean section (adjusted odds ratio (aOR) 1.81, 95% CI 1.24-2.65) and preterm (<37 weeks, aOR: 2.52, 95% CI 1.56-4.08) or very preterm delivery (<32 weeks, aOR: 7.02 95% CI 2.41-20.46) in subsequent pregnancies than women who did not have a history of RM.
Conclusion: Women with a history of RM were twice as likely to undergo cesarean section and seven times more likely to deliver prior to 32 weeks of gestation than women without a history of RM. The study findings support the need for early pregnancy monitoring or assessment units to ensure better follow-up and customized care for at-risk pregnant women with a history of RM.

Background: Recurrent spontaneous abortion (RSA), whose underlying cause has yet to be fully elucidated, is often classified as unexplained recurrent spontaneous abortion (URSA). Promoting the differentiation of CD4 T cells into Tregs may be the key to prevent URSA. The differentiation of CD4 T cells was controlled by mTOR, but the regulatory mechanism is still unclear.
Background: Maternal infections caused by the ToRCH complex, comprising Toxoplasma gondii (T.gondii), Rubella Virus (RV), Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV), are significant contributors to Bad Obstetric History (BOH). These infections can vertically transmit through the placental barrier, leading to complications in fetal development.
Haemolytic disease of the foetus and newborn (HDFN) due to Rhesus D (RhD) antigen mismatch between the mother and foetus has been a significant cause of neonatal jaundice, recurrent miscarriage and stillbirth throughout history. Anti-RhD prophylaxis using polyclonal immunoglobulin G (RhD-pIgG) derived from the plasma of RhD-negative donors immunised with RhD-positive red blood cells (RBCs), has reduced the incidence of HDFN, but this approach is currently restricted to developed countries. Monoclonal antibodies (mAbs) offer a promising alternative to address this pressing need, but prior attempts to develop effective anti-RhD mAbs have failed, in some cases due to differences in fucosylation patterns between mAbs produced in cell lines and RhD-pIgG.
SOX2 overlapping transcript (SOX2-OT) is a long non-coding RNA located at chromosome 3q26.33 in humans. Convincing data confirm that SOX2-OT is evolutionarily conserved and plays a significant role in various malignant and non-malignant diseases.
Background: The treatment for recurrent pregnancy loss (RPL) has been addressed in international guidelines. However, limited studies have investigated the risk factors associated with pregnancy and live birth outcomes in patients with RPL after treatment. The objective of this study was to offer a comprehensive assessment of the risk factors for pregnancy loss in patients with a history of RPL following therapeutic interventions.
