Women who are receiving an oral anticoagulant appear to be at higher risk of developing bleeding-related adverse events than men. Physiological bleeding related to the ovulatory cycle poses an ongoing risk for bleeding complications during anticoagulant therapy. Abnormal uterine bleeding and hemorrhagic ovarian cysts are risks specific to women of reproductive age who are treated with anticoagulants. The use of combined oral contraceptives can help minimize such adverse events and would also mitigate the risks of obstetrical complications related to thrombosis and anticoagulation, in addition to avoiding fetal exposure to potentially teratogenic anticoagulants...

Compared to standard component therapy, fresh whole blood (FWB) offers potential benefits to neonates undergoing cardiopulmonary bypass (CPB) in the context of open cardiac surgery: decreased blood loss and subsequent risk of volume overload, improved coagulation status, higher platelet counts during and following CPB, circumvention of limited vascular access, and significantly reduced donor exposures. Obtaining FWB, however, entails 2-5 days of preparation, which often precludes its availability for neonates requiring CPB in the immediate newborn period...

Generating an unlimited source of human insulin-producing cells is a prerequisite to advance β cell replacement therapy for diabetes. Here, we describe a 3D culture system that supports the expansion of adult human pancreatic tissue and the generation of a cell subpopulation with progenitor characteristics. These cells display high aldehyde dehydrogenase activity (ALDHhi ), express pancreatic progenitors markers (PDX1, PTF1A, CPA1, and MYC), and can form new organoids in contrast to ALDHlo cells. Interestingly, gene expression profiling revealed that ALDHhi cells are closer to human fetal pancreatic tissue compared with adult pancreatic tissue...

The rising prevalence of chronic liver disease, coupled with a permanent shortage of organs for liver transplantation, has sparked enormous interest in alternative treatment strategies. Previous protocols to generate hepatocyte-like cells (HLCs) via pancreas-to-liver transdifferentiation have utilised fetal bovine serum, introducing unknown variables and severely limiting study reproducibility. Therefore, the main goal of this study was to develop a protocol for transdifferentiation of pancreatic progenitor cells to HLCs in a chemically defined, serum-free culture medium...

With fewer than 200 reported cases, Cushing's syndrome (CS) in pregnancy remains a diagnostic and therapeutic challenge. In normal pregnancies, misleading signs may be observed such as striae or hypokalemia, while plasma cortisol and urinary free cortisol may rise up to 2-3-fold. While the dexamethasone suppression test is difficult to use, reference values for salivary cortisol appear valid. The predominant cause is adrenal adenoma (sometimes without decreased ACTH), rather than Cushing's disease. There are considerable imaging pitfalls in Cushing's disease...

Naturally occurring, large deletions in the β-globin locus result in hereditary persistence of fetal hemoglobin, a condition that mitigates the clinical severity of sickle-cell disease (SCD) and β-thalassemia. We designed a CRISPR/Cas9 strategy to disrupt a 13.6-kb genomic region encompassing the δ- and β-globin genes and a putative γ-δ intergenic fetal hemoglobin (HbF) silencer. Disruption of just the putative HbF silencer results in a mild increase in γ-globin expression, whereas deletion or inversion of a 13...

Background: Recently discovered drugs that target epigenetic modifying complexes are providing new treatment options for a range of cancers that affect patients of reproductive age. Although these drugs provide new therapies, it is likely that they will also affect epigenetic programming in sperm and oocytes. A promising target is Enhancer of Zeste 2 (EZH2), which establishes the essential epigenetic modification, H3K27me3, during development. Results: In this study, we demonstrate that inhibition of EZH1/2 with the clinically relevant drug, tazemetostat, severely depletes H3K27me3 in growing oocytes of adult female mice...

Breast cancer is a common malignant tumor in women. It has been suggested that a type of microcirculation pattern that does not rely on host microvascular endothelial cells known as vasculogenic mimicry (VM) may contribute to the poor effect of anti‑angiogenesis treatment on some patients with breast cancer. However, the formation and regulatory mechanism of VM in breast cancer are unclear and still require further investigation. The present study examined whether decreasing the expression of zinc finger E‑box binding homeobox (ZEB1) using siRNA can inhibit the formation of VM in Triple Negative Breast Cancer (TNBC), and its specific function and molecular mechanism...

Isotretinoin has revolutionized the treatment of severe acne vulgaris, a condition which if left untreated may result in significant socio-psychological implications for those affected. Timely access to isotretinoin therapy is important to avoid the risks of potential physical and emotional scarring. However, due to its high risks of teratogenicity, isotretinoin must be used with care in females of childbearing potential. Since isotretinoin's introduction, numerous risk management programs have been implemented across the world in an attempt to prevent isotretinoin use in pregnancy...

Treatment during pregnancy is problematic. The Food and Drug Administration established drug categories to help in the treatment process. First-generation antihistamines are considered safe but they have sedative properties. Second-generation antihistamines cause less adverse reactions but besides cetirizine and loratadine they belong to category C. All retinoids should be avoided during pregnancy due to the risk of fetal malformations. Antimalarial drugs should be considered based on the clinical data. Sulfones can be considered as safe for use during pregnancy only with proper monitoring...

BACKGROUND: Preeclampsia (PE) is the most common complication of pregnancy that remains to be a major cause of maternal and fetal mortality. Prediction and early diagnosis of PE would allow for timely initiation of preventive therapy. According to recent studies of ACVR2A gene polymorphism is associated with PE, but it is still unclear whether these findings reflect specific pathogenetic mechanisms of this disease. METHODS: We performed targeted next-generation sequencing (NGS) sequencing of ACVR2A gene by means of Ion Torrent Personal Genome machine (PGM) Sequencer...
