In the last decade, diagnosis of caesarean scar (CS) pregnancy and abnormal placental invasion has gone up significantly. It appears that the history of previous caesarean section is the predisposing factor common to both conditions. Until now, these are treated as a separate entity and therefore managed differently. Recent available ...

Most policies and guidelines recommend that women abstain from alcohol during pregnancy. This can be difficult to achieve in developed nations where the majority of women consume alcohol and almost half of pregnancies are unplanned, leading to many pregnancies being exposed to alcohol prior to pregnancy awareness. Concerns have been ...

Abstract There is increasing evidence of the adverse impact of prenatal exposure to air pollution. This is of particular interest, as exposure during pregnancy-a crucial time span of important biological development-may have long-term implications. The aims of this review are to show current epidemiological evidence of known effects of prenatal ...

The association between lead and hypertension in adults was first identified in the early 1980's and it has since been proposed that lead may also have a role in gestational hypertension (GH). This systematic review investigates whether lead may be associated with the development of GH or pre-eclampsia. MEDLINE, Embase ...

BACKGROUND: Cancer is the second leading cause of death among women of reproductive age. Although the coincidence of pregnancy and cancer is rare and treatment may sometimes be safely delayed, the use of chemotherapeutic agents in pregnancy is sometimes unavoidable or inadvertent. METHODS: We review the literature for the use ...

Maternal exposure to ambient air pollution has been associated with adverse birth outcomes such as preterm delivery. However, only one study to date has linked air pollution to blood pressure changes during pregnancy, a period of dramatic cardiovascular function changes. Objectives: We examined whether maternal exposures to criteria air pollutants, ...

BACKGROUND: Epidemiologic studies suggest an association between air pollution exposure and foetal growth. The possible underlying biological mechanisms have little been studied in humans, but animal studies suggest an impact of atmospheric pollutants on placental function. OBJECTIVES: Our aim was to investigate the association between exposure to atmospheric pollutants' levels ...

Adverse birth outcomes are associated with exposure to air pollution during pregnancy. Road proximity is a simple, widely available metric for capturing local variation in exposure to traffic-related air pollution. We characterized maternal exposure to traffic-related air pollution during pregnancy using residential proximity to major roadways among 2004-2008 singleton births ...

Drugs that interfere with the renin-angiotensin system, such as angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), are widely used to manage hypertension and heart failure. Adequate functioning of the RAS is essential for normal fetal kidney development. The potential for ACEIs and ARBs to impair fetal and neonatal ...

Anti-tumor necrosis factor (TNF) α medications are used for the treatment of a number of autoimmune diseases. Evaluation of pregnancy safety for these medications is complicated by the contribution of the underlying maternal disease to adverse pregnancy outcomes, such as preterm delivery and reduced birth weight. Placental transport of these ...

Retained placenta membranes and tissue are responsible for 5% to 10% of postpartum hemorrhage. Placenta accreta occurs in approximately 1 in 2500 pregnancies of which placenta percreta constitutes about 5% of placenta accreta. This portends the rarity of placenta percreta especially in a 32 year old woman with minimal risk ...

BACKGROUND The second generation antiepileptic drugs (AEDs), which include lamotrigine, topiramate, and gabapentin, have been introduced during the past 20 years. Because the newer AEDs differ in their pharmacokinetics from the first generation AEDs, it is hoped that the second generation AEDs will be less teratogenic. METHODS The findings in ...

BACKGROUND: Studies emphasize the importance of particulate matter (PM) in the formation of reactive oxygen species and inflammation. We hypothesized that these processes can influence mitochondrial function of the placenta and fetus. OBJECTIVES: We investigated the influence of PM10 exposure during pregnancy on the mitochondrial DNA-content (mtDNA content) of the ...

Studies on environmental exposures during pregnancy often have limited residential history (e.g., at delivery), potentially introducing exposure misclassification. We reviewed studies reporting residential mobility during pregnancy to summarize current evidence and discuss research implications. A meaningful quantitative combination of results (e.g., meta-analysis), was infeasible owing to variation in study designs. ...
