Fetuses with exomphalos have an increased risk for chromosomal abnormalities. [7]Both exomphalos and gastroschisis have been linked to conditions affecting placental insufficiency, including maternal illness and infection, drug dependency and smoking. One study also found that ibuprofen during early pregnancy was a moderate risk factor for gastroschisis. Alcohol was a moderate risk factor for g...

background: the pregnancy was a risk factor for excessive weight gain for women. however, there is no information about the prevalence of obesity and its relationship with a history of pregnancy in girls. therefore, the purpose of this study was to investigate differences in the prevalence of obesity in adolescent females with a history of pregnancy and fac­tors associated with it, in korea. me...

Background: Disturbances in glucose metabolism during pregnancy are associated with negative sequalae for both mother and infant. The association between smoking and abnormal glucose tolerance (AGT) remains controversial. Therefore, the aim of this study was to examine the relationship between smoking prior to and during pregnancy and risk of AGT. Methods: We utilized data from a prospective co...

BACKGROUND Elevated serum concentrations of insulin-like growth factor (IGF)-I have been associated with increased risk of developing breast cancer. Previously, we reported a similar association in samples obtained during pregnancy. This study was conducted to further characterize the association of IGF-I during pregnancy with maternal breast cancer risk. METHODS A case-control study was nest...

background: preterm birth (ptb) is responsible for 70% of neonatal mortalities. various factors influence the risk of neonatal mortality in different populations. objective: our objective was to evaluate neonatal survival rate of preterm infants, and to define its predictors in iranian population. materials and methods: this retrospective cohort study included all preterm (26-37 weeks) infants ...

INTRODUCTION The association between hypertensive pregnancy disorders and cardiovascular disease later in life is well described. In this study we aim to develop a prognostic model from patients characteristics known before, early in, during and after pregnancy to identify women at increased risk of cardiovascular disease e.g. chronic hypertension years after pregnancy complicated by hypertensi...

The potential benefits and risks of physical activity before and during pregnancy are not well studied. We studied the relation between recreational physical activity and the risk of preeclampsia in a case-control study of 201 preeclamptic and 383 normotensive pregnant women. Participants provided information about the type, intensity, frequency, and duration of physical activity performed duri...

background: gonadotropin-releasing hormone (gnrh) plays essential roles in embryo implantation, invasion of trophoblastic tissue, and steroid synthesis in the placenta. objective: the aim of this study was to evaluate the effect of gnrh antagonist administration on pregnancy outcomes in early implantation period. materials and methods: in this retrospective study, 94 infertile women undergoing ...
