Background : Pre-eclampsia (PE) is a major pregnancy disorder complicating up to 8% of pregnancies. Increasing evidence indicates a sex-specific interplay between the mother, placenta and fetus. This may lead to different adaptive mechanisms during pregnancy. Methods We performed an individual participant data meta-analysis to determine associations of fetal sex and PE, with specific focus on...
Postdate pregnancy is estimated to occur in 3% to 12% of all gestations. Morbidity and mortality rates associated with this common obstetric problem are higher than those with term gestation. The incidence of fetal distress, birth injury, meconium aspiration, congenital malformations, macrosomia, and oligohydramnios is also greater in postdate pregnancies. We prospectively evaluated breast ...
Maternal immune tolerance of the semiallogeneic fetus is a complex phenomenon. Macrophages are an abundant cell population in the human decidua, and changes in distribution or phenotype may be involved in the development of preeclampsia. The aim of this study was to assess the distribution and phenotype of macrophages in preterm preeclamptic, preterm control, and term control placentas. Placent...
Qualitative data gathered from women in Nairobi, Kenya, were used to explore decision making in relation to unwanted pregnancy. Gender, livelihoods, morality, marital status, and male partners exerted extensively complex and multidimensional influence on women’s management of their unintentional pregnancies. For instance, although gender norms were frequently invoked to justify terminating unwa...
Pregnancy increases metabolic demand for insulin and may lead to the exhaustion of intraportally transplanted islets post-gestational hyperglycemia. To prevent these complications, we implemented preemptive supplementation during two subsequent pregnancies in an insulin-independent islet transplant recipient. This strategy resulted optimal blood glucose control pregnancies, preservation graft f...
The aim of the study was to demonstrate that preterm birth (PTB) is associated with altered C19MC microRNA expression profile in placental tissues. Gene expression of 15 placental specific microRNAs (miR‑512‑5p, miR‑515‑5p, miR‑516‑5p, miR‑517‑5p, miR‑518b, miR‑518f‑5p, miR‑519a, miR‑519d, miR‑519e‑5p, miR‑520a‑5p, miR‑520h, miR‑524‑5p, miR‑525‑5p, miR‑526a and miR‑526b‑5p) was compared between...
background: the increase in the prevalence of cesarean section (c-section) in recent decades has become a public health problem worldwide. studies of cesarean section in order to identify the causes and form policies and interventions to reduce the incidence of this health problem are necessary. this study was conducted with the aim to investigate the causes of c-sections performed at niknafs a...
Considering the increasing trend for ectopic pregnancies in the world and different reports on its complications and the fate of the following pregnancies, this study was performed to determine the relationship between these factors in referrals of the hospitals of Shaheed Beheshti University of Medical Sciences from 1991 to 1996. The cohort strategy of this research study was carried out on 2...
