A distinctive type of (uterine) natural killer (NK) cell is present in the uterine decidua during the period of placental formation. Uterine NK cells express members of the killer immunoglobulin-like receptor (KIR) family that bind to parental HLA-C molecules on the invading placental trophoblast cells. The maternal KIR genes and their fetal ligands are highly variable, so different KIR/HLA-C genetic combinations occur in each pregnancy. Some women only possess inhibitory KIR genes, whereas other women also express activating KIR genes...

In this exciting era of "next-gen cytogenetics," integrating genomic sequencing into the prenatal diagnostic setting is possible within an actionable time frame and can provide precise delineation of balanced chromosomal rearrangements at the nucleotide level. Given the increased risk of congenital abnormalities in newborns with de novo balanced chromosomal rearrangements, comprehensive interpretation of breakpoints could substantially improve prediction of phenotypic outcomes and support perinatal medical care...

Variation in female reproductive traits, such as fertility, fecundity, and fecundability, is heritable in humans, but identifying and functionally characterizing genetic variants associated with these traits has been challenging. Here, we explore the functional significance and evolutionary history of a T/C polymorphism of SNP rs2071473, which we have previously shown is an eQTL for TAP2 and significantly associated with fecundability (time to pregnancy). We replicated the association between the rs2071473 genotype and TAP2 expression by using GTEx data and demonstrated that TAP2 is expressed by decidual stromal cells at the maternal-fetal interface...

Pregnancy is associated with a hypercoagulable state. Women requiring anticoagulation need careful attention throughout pregnancy and the post-partum period. The choice of anticoagulant therapy, the degree of monitoring, and the therapeutic target should be modulated by balancing the risks and the benefits to the mother and fetus. Many of the available anticoagulant agents may be used safely in pregnancy, but they are disadvantaged by competing efficacy and risks to the mother and fetus. For example, vitamin K antagonists are the most efficacious for preventing mechanical valve thrombosis, but they pose risks to the fetus...

The Zika emergency calls for urgent countermeasures. Recently, Barrows et al. (2016) and Xu et al. (2016) conducted in vitro anti-ZIKV screens to identify potential therapeutics. The off-label use of drugs that may protect against Zika virus-induced brain damage has, however, to be balanced with their risk during pregnancy.

STUDY QUESTION: Does antisense oligonucleotide (ASO)-mediated down-regulation of serum fetuin-B cause an infertility-like fetuin-B gene deficiency in female mice? SUMMARY ANSWER: Pharmacological fetuin-B down-regulation by ASO therapy results in reversible infertility in female mice. WHAT IS KNOWN ALREADY: Female fetuin-B deficient (Fetub(-/-)) mice are infertile owing to premature zona pellucida (ZP) hardening. Enzyme activity studies demonstrated that fetuin-B is a potent and highly specific inhibitor of the zona proteinase ovastacin, which cleaves ZP protein 2 (ZP2) and thus mediates definitive ZP hardening...

OBJECTIVE: Methotrexate is routinely used worldwide for medical treatment of clinically stable women with tubal ectopic pregnancies. This is despite the lack of robust evidence to show its superior effectiveness over expectant management. The aim of our multicentre randomised trial study was to compare the success rates of methotrexate with placebo for the conservative treatment of tubal ectopic pregnancies. METHODS: The study was multicentre; it took place in three UK early pregnancy units between January 2006 and June 2014...

Alterations in normal balance of B cell subsets have been reported in various rheumatic diseases. In this study, we report a woman with a history of recurrent pregnancy losses (RPL) and infertility who had low levels of memory B cells. A 35-year-old woman with a history of RPL and infertility was demonstrated to have increased peripheral blood CD19+ B cells with persistently low levels of memory B cell subsets. Prior to the frozen donor egg transfer cycle, prednisone and intravenous immunoglobulin G (IVIg) treatment was initiated and patient achieved dichorionic diamniotic twin pregnancies...

This experiment was designed to evaluate split-time artificial insemination (AI) in beef heifers following administration of the 14-day controlled internal drug release (CIDR)-prostaglandin F2α (PG) protocol and to compare pregnancy rates among nonestrous heifers based on administration of GnRH at AI. Estrus was synchronized for 1138 heifers across six locations. Heifers received a CIDR insert (1.38 g progesterone) on Day 0 with removal on Day 14. Estrus detection aids (Estrotect) were applied at PG (25 mg), 16 days after CIDR removal on Day 30...

Balanced translocation is a common structural chromosomal rearrangement in humans. Carriers can be phenotypically normal but have an increased risk of pregnancy loss, fetal death, and the transmission of chromosomal abnormalities to their offspring. Existing prenatal screening technologies and diagnostic procedures fail to detect balanced translocation, so genetic counseling for carriers remains a challenge. Here, we report the characteristics of chromosomal reciprocal translocation in 3807 amniocentesis cases...

Epilepsy is one of the few neurologic disorders that requires a constant treatment during pregnancy. Epilepsy affects 0.3-0.8% of pregnant women. Prescription of antiepileptic drugs (AEDs) to pregnant women with epilepsy requires monitoring and maintaining a balance between limiting seizures and decreasing fetal exposure to the potential teratogenic effects. AEDs are also commonly used for psychiatric disorders, pain disorders, and migraines. The types of malformations that can result in fetuses exposed to AEDs include minor anomalies, major congenital malformations, intrauterine growth retardation, cognitive dysfunction, low IQ, microcephaly, and infant mortality...

Whole-body protein deposition (Pd) is a main determinant of AA requirements of gestating gilts; however, data on the dynamics of Pd is limited. The main objective of this study was to measure whole-body Pd (pregnancy-associated and maternal) during gestation in gilts at 2 feeding levels. Changes in BW and backfat (BF) throughout gestation and subsequent lactation performance were also evaluated. We hypothesized that the effect of feed intake on maternal Pd decreases toward the end of gestation due to increased fetal nutrient demands...

Preimplantation genetic screening (PGS) is widely used to select in vitro-fertilized embryos free of chromosomal abnormalities and to improve the clinical outcome of in vitro fertilization (IVF). A disadvantage of PGS is that it requires biopsy of the preimplantation human embryo, which can limit the clinical applicability of PGS due to the invasiveness and complexity of the process. Here, we present and validate a noninvasive chromosome screening (NICS) method based on sequencing the genomic DNA secreted into the culture medium from the human blastocyst...

The safety of combined hormonal contraceptives (CHCs) has been documented by years of follow-up, and the occurrence of venous thromboembolism (VTE) possibly related to their use is rare in the young population exposed to these agents. The balance between the benefits and risks of contraceptive steroids is generally positive, in particular when compared with pregnancy's risks. Epidemiological studies led to different results showing either no difference in VTE risk between CHCs (active surveillance prospective studies) or an increase in risk (observational or database studies)...

OBJECTIVE: Neuraxial hematoma is a rare complication of spinal or epidural anesthesia. However, variable coagulation factor defects are relatively common in patients with Fontan circulation, and may predispose such patients to either increased risk of thrombosis or coagulopathy. These defects may indirectly increase their risk of neuraxial hematoma. CASE REPORT: We report a case of delayed neuraxial hematoma after the start of full-dose anticoagulation for pulmonary embolus on a postpartum patient with Fontan physiology who had continuous spinal anesthesia for cesarean delivery 4 days earlier...

Assisted reproductive technology (ART) is widely used for the women with infertility conditions to achieve pregnancy. However, the adverse effects of ART may lead to poor perinatal and neonatal outcomes, e.g., preterm birth and low body weight. In this study, we investigated the inflammatory molecular factors and microRNA that might be involved in ART related preterm birth. We found the elevation of Toll-like 4 receptor (TLR4), activation of NFκB pathway and down-regulation of microRNA-146a (miR-146a), a negative regulator of NFκB, in the placenta of preterm birth and ART, indicating preterm birth and ART were associated with inflammation signaling activation...

The aim of this study was to establish the serum concentrations, ranges, and trends of Th1 type cytokine (tumor necrosis factor (TNF)-α and interleukin (IL)-2), Th2 type cytokine (IL-10), and nitric oxide (NO) during the estrous cycle, early pregnancy and abortion in goats. Boer goats (n=25) having symptoms of normal estrous cycles were selected, 20 were mated and 15 conceived a pregnancy, and the remaining five were not mated and served as estrous controls. On the Day 60 of pregnancy, all 15 pregnant goats were induced to abort the pregnancy by intramuscular injection of prostaglandin (PG)...

BACKGROUND: Pregnant women with venous thromboembolism are traditionally managed with anticoagulation, but inferior vena cava filters are an alternative. We balanced risks and benefits of an inferior vena cava filter in a decision analysis. METHODS: We constructed a decision model to compare in pregnant women with VTE the outcome of (1) inferior vena cava filter and anticoagulant treatment versus (2) anticoagulant treatment only. RESULTS: Assuming a 63% risk reduction from an inferior vena cava filter (baseline mortality rate of venous thromboembolism of 0...
