Superficial vein thrombosis, a less hazardous and less studied type of thrombosis in pregnant women, is beyond the scope of this review. This study discusses the VTE incidence rate in women from developed countries for both antepartum and postpartum periods and for subpopulations of women affected by additional risk factors, such as thrombophilias, circulatory diseases, preeclampsia of varying degrees of severity, and Caesarean section. To minimize bias due to historical changes in medical and obstetric practices, lifestyle, diet, etc., this review is generally limited to relatively recent studies, i.e., those that cover the last 35 years. The absolute risk or incidence rate was used to ascertain risk of VTE associated with pregnancy. For the studies where the direct incidence rates of VTE were not reported, we calculated an estimate of the observed but not reported absolute incidence rates using the data presented in respective articles.

Barnea,&nbsp;Michael J. Paidas","doi":"10.1002/bdrc.21103","DOIUrl":"10.1002/bdrc.21103","url":null,"abstract":"<p>Maternal thromboembolism and a spectrum of placenta-mediated complications including the pre-eclampsia syndromes, fetal growth restriction, fetal loss, and abruption manifest a shared etiopathogenesis and predisposing risk factors. Furthermore, these maternal and fetal complications are often linked to subsequent maternal health consequences that comprise the metabolic syndrome, namely, thromboembolism, chronic hypertension, and type II diabetes. Traditionally, several lines of evidence have linked vasoconstriction, excessive thrombosis and inflammation, and impaired trophoblast invasion at the uteroplacental interface as hallmark features of the placental complications. “Omic” technologies and biomarker development have been largely based upon advances in vascular biology, improved understanding of the molecular basis and biochemical pathways responsible for the clinically relevant diseases, and increasingly robust large cohort and/or registry based studies. Advances in understanding of innate and adaptive immunity appear to play an important role in several pregnancy complications. Strategies aimed at improving prediction of these pregnancy complications are often incorporating hemodynamic blood flow data using non-invasive imaging technologies of the utero-placental and maternal circulations early in pregnancy. Some evidence suggests that a multiple marker approach will yield the best performing prediction tools, which may then in turn offer the possibility of early intervention to prevent or ameliorate these pregnancy complications. Prediction of maternal cardiovascular and non-cardiovascular consequences following pregnancy represents an important area of future research, which may have significant public health consequences not only for cardiovascular disease, but also for a variety of other disorders, such as autoimmune and neurodegenerative diseases.

Endothelial injury, alterations in blood flow and activation of the coagulation pathway are proposed to contribute to the hypercoagulability. The risk for thrombosis may be accentuated by certain drugs and device implants that directly or indirectly affect the coagulation pathway. To help ensure that these interventions do not result in adverse maternal or fetal outcomes during pregnancy, gravid experimental animals can be exposed to such treatments at various stages of gestation and over a dosage range that would identify hazards and inform risk assessment. Circulating soluble biomarkers can also be evaluated for enhancing the assessment of any increased risk of venous thrombosis during pregnancy. In addition to traditional <i>in vivo</i> animal testing, efforts are under way to incorporate reliable non-animal methods in the assessment of embryofetal toxicity and thrombogenic effects. This review summarizes hemostatic balance during pregnancy in animal species, embryofetal development, biomarkers of venous thrombosis, and alterations caused by drug-induced venous thrombosis.

Pregnancy and the puerperium are associated with a fourfold to fivefold increased risk of thrombosis when compared with the nonpregnant state. The greatest time of risk is in the postpartum period. Diagnosis of venous thromboembolism (VTE) during pregnancy can be challenging as many of the symptoms can be associated with normal pregnancy. Almost all deep venous thrombosis occurs in the left leg or iliac veins. Diagnostic procedures for pulmonary embolism carry some exposure to radiation, although risks are low when compared with risks associated with an undiagnosed maternal PE. The anticoagulant of choice during pregnancy is low-molecular-weight heparin. Certain medical conditions require alternative approaches as management around the time of delivery. In women with VTE during pregnancy, anticoagulation should continue for at least 3 months and until at least 6 weeks postpartum.

In the obstetric population, recurrent early pregnancy loss, fetal loss, and thrombosis are hallmarks of the disease. Patients with APLS have developed one or more pathogenic auto-antibodies directed against plasma and cell surface proteins. These antibodies are characterized by their affinity for anionic phospholipids. Interactions between APLS antibodies and their protein targets influence a wide variety of biological systems and signaling pathways, including monocytes, platelets, the complement system, and endothelial cells. While much research is currently directed at understanding the mechanisms involved in this autoimmune disease, the key clinical presentation is the hypercoagulable state resulting in thrombosis occurring in essentially any arterial or venous location, as well as numerous obstetrical complications. Treatment of APLS is generally directed at preventing thrombosis and poor pregnancy outcomes by ameliorating the hypercoagulable state.

Seventy-five to eighty percent of pregnancy-related thrombotic events are venous and twenty to –twenty-five percent are arterial. The main reason for the increased risk is hypercoagulability. Women are hypercoagulable because they have evolved so that they are protected against the bleeding challenges of pregnancy, miscarriage, or childbirth. Both genetic and acquired risk factors can further increase the risk of thrombosis. The maternal consequences of thrombosis of pregnancy include permanent vascular damage, disability, and death. While the maternal outcomes of thrombosis can be modified by anticoagulation therapy, management of thrombosis during pregnancy is the subject of another paper in this issue (see paper by B. Konkle).

These sensory neurons are unique in that they have dendrites contacting the outside world, yet their first synapse lies in the central nervous system. The information entering the central nervous system is used to create odor memories that play a profound role in recognition of individuals, places, and appropriate foods. Here, the structure of the olfactory epithelium is given as an overview to discuss the origin of the olfactory placode, the plasticity of the olfactory sensory neurons, and finally the origins of the gonadotropin-releasing hormone neuroendocrine cells. For the purposes of this review, the development of the peripheral sensory system will be analyzed, incorporating recently published studies highlighting the potential novelties in development mechanisms. Specifically, an emerging model where the olfactory epithelium and olfactory bulb develop simultaneously from a continuous neurectoderm patterned at the end of gastrulation, and the multiple origins of the gonadotropin-releasing hormone neuroendocrine cells associated with the olfactory sensory system development will be presented. Advances in the understanding of the basic mechanisms underlying olfactory sensory system development allows for a more thorough understanding of the potential causes of human disease.

Each hair cell detects the mechanical stimuli associated with sound or head movement with a hair bundle at the apical surface of the cell, consisting of a precise array of actin-based stereocilia. Each stereocilium inserts as a rootlet into a dense filamentous actin mesh known as the cuticular plate. Disruption of the parallel actin bundles forming the stereocilia results in hearing impairments and balance defects. The cuticular plate is thought to be involved in holding the stereocilia in place. However, the precise role of the cuticular plate in hair bundle development, maintenance, and hearing remains unknown. Ultrastructural studies have revealed a complex cytoskeletal architecture, but a lack of knowledge of proteins that inhabit the cuticular plate and a dearth of mutations that perturb relevant proteins have hindered our understanding of the functions of the cuticular plate. Here, we discuss what is known about the structure and development of this unique and poorly-understood actin-rich organelle.

Despite this, the drug is now used successfully to treat a range of adult conditions, including multiple myeloma and complications of leprosy. Tragically, a new generation of thalidomide damaged children has been identified in Brazil. Yet, how thalidomide caused its devastating effects in the forming embryo remains unclear. However, studies in the past few years have greatly enhanced our understanding of the molecular mechanisms the drug. This review will look at the history of the drug, and the range and type of damage the drug caused, and outline the mechanisms of action the drug uses including recent molecular advances and new findings.
