background: lead toxicity is a prevalent health problem in both developed and developing countries. one of the proposed mechanisms for lead-induced organ damage is oxidative stress. oxidative stress is well-associated with the pregnancy disorder, pre-eclampsia. exposure to lead may be one of the sources of the oxidative stress that leads to development of pre-eclampsia in pregnant women. object...

background: more and more infertile patients have accepted the assisted reproductive technique (art) therapy. concerns have been raised over an increased risk of adverse maternal outcomes in art populations as compared with natural conception (nc). objective: the aim was to improve the art in clinicial work and to reduce the incidence of pregnancy complications in art group according to analyzi...

There have been a number of studies evaluating the association of aneuploidy serum markers with adverse pregnancy outcome. More recently, the development of potential treatments for these adverse outcomes as well as the introduction of cell-free fetal DNA (cffDNA) screening for aneuploidy necessitates a re-evaluation of the benefit of serum markers in the identification of adverse outcomes. Ana...

Background & aim: Nausea and vomiting are among the most common complaints during pregnancy observed in patients with severe pregnancy outcomes. The purpose of this study was to investigate the relationship of nausea and vomiting during pregnancy (NVP) with some pregnancy complications. Methods: This cross-secti...

context maternal serum human chorionic gonadotropin (hcg) and alpha fetal protein (afp) were originally introduced to detect trisomy 21 and neural tube defects. however, in the absence of aneuploidy or neural tube defects, mid-trimester maternal serum hcg and/or maternal serum afp associated with adverse pregnancy outcomes. pregnancies with unexplained mid-trimester elevation in maternal serum ...

abstract background: hypertensive disorders in pregnancy are the main cause of maternal and fetal mortality; however, they have no definite effective treatment. the researchers aimed to study the effects of progressive muscular relaxation and breathing control technique on blood pressure (bp) during pregnancy. materials and methods: this three‑group clinical trial was conducted in mashhad healt...

The purpose of the paper is to examine the factors affecting pregnancy complications during antenatal period of mothers. The study uses data which have been repeated over time i.e., the nature of the data is longitudinal in type. Thus the generalized estimating equation (GEE) method has been employed to identify the factors associated with the pregnancy complications which constitute binary res...
