Transfer of embryos with positive PGT-M results: Genetic Counselors' perspectives and ethical considerations.

Increasing numbers of fertility patients use preimplantation genetic testing for monogenic conditions (PGT-M) during in vitro fertilization (IVF). While PGT-M is primarily used to avoid implanting embryos with a monogenic condition, patients can request to transfer an embryo with the monogenic condition (positive embryo transfer), especially in cases where an IVF cycle results in no unaffected embryos. Transferring embryos with known disease-causing variants raises ethical concerns.

SF3B1-dependent alternative splicing is critical for maintaining endometrial homeostasis and the establishment of pregnancy.

The remarkable potential of human endometrium to undergo spontaneous remodeling is shaped by controlled spatiotemporal gene expression patterns. Although hormone-driven transcription shown to govern these patterns, the post-transcriptional processing of these mRNA transcripts, including the mRNA splicing in the endometrium is not studied yet. Here, we report that the splicing factor, SF3B1 is central in driving alternative splicing (AS) events that are vital for physiological responses of the endometrium.

Organ Donation Organization Architecture: Recommendations From an International Consensus Forum.

Unlabelled: This report contains recommendations from 1 of 7 domains of the International Donation and Transplantation Legislative and Policy Forum (the Forum). The purpose is to provide expert guidance on the structure and function of Organ and Tissue Donation and Transplantation (OTDT) systems. The intended audience is OTDT stakeholders working to establish or improve existing systems.

Embryo Cryopreservation in a Patient with Sickle Cell Disease Utilizing Letrozole and Enoxaparin: A Case Report.

Purpose: To describe a patient with sickle cell disease, a prothrombotic disorder, who underwent successful embryo cryopreservation for the purposes of fertility preservation prior to hematopoietic stem cell transplant.

Methods: To report a successful case of gonadotropin stimulation and embryo cryopreservation using the aromatase inhibitor letrozole to maintain low serum estradiol to minimize thrombotic risk in a patient with sickle cell disease (SCD) and history of retinal artery thrombosis planning hematopoietic stem cell transplant (HSCT). The patient was given letrozole (5 mg daily) as well as prophylactic enoxaparin while undergoing gonadotropin stimulation with an antagonist protocol to preserve fertility prior to HSCT.

Association of the human semen DNA virome with successful in vitro fertilization.

Objective: To comprehensively characterize the DNA virome in semen samples collected for in vitro fertilization (IVF).

Design: A descriptive clinical study.

Setting: Single academic fertility center.

Public reporting of IVF outcomes influences medical decision-making and physician training.

Background: Since 1992 ART clinics have been required to report outcome data. Our objective was to assess practitioners' opinions of the impact of public reporting of assisted reproductive technology (ART) outcomes on treatment strategies, medical decision-making, and fellow training.

Methods: Survey study performed in an academic medical center.

Membrane Potential Determined by Flow Cytometry Predicts Fertilizing Ability of Human Sperm.

Infertility affects 10 to 15% of couples worldwide, with a male factor contributing up to 50% of these cases. The primary tool for diagnosing male infertility is traditional semen analysis, which reveals sperm concentration, morphology, and motility. However, 25% of infertile men are diagnosed as normozoospermic, meaning that, in many cases, normal-appearing sperm fail to fertilize an egg.

Role of Transmembrane Proteins for Phase Separation and Domain Registration in Asymmetric Lipid Bilayers.

It is well known that the formation and spatial correlation of lipid domains in the two apposed leaflets of a bilayer are influenced by weak lipid-lipid interactions across the bilayer's midplane. Transmembrane proteins span through both leaflets and thus offer an alternative domain coupling mechanism. Using a mean-field approximation of a simple bilayer-type lattice model, with two two-dimensional lattices stacked one on top of the other, we explore the role of this "structural" inter-leaflet coupling for the ability of a lipid membrane to phase separate and form spatially correlated domains.

Complications of Assisted Reproductive Technology.

Although only accounting for a small percentage of infants born in the United States each year, assisted reproductive technology (ART) has become a more common means of conception since the first in vitro fertilization baby was born in 1978. An understanding of the ART process, medications, and complications is becoming essential for emergency medicine practice. Much of the surveillance data focuses on ART complications that are likely to be less relevant in the acute care setting, but ovarian hyperstimulation syndrome, ectopic pregnancy, and ovarian torsion are 3 diagnoses with high potential morbidity and mortality that emergency physicians should not miss.

Delivering information about medication assisted treatment to individuals who misuse opioids through a mobile app: a pilot study.

Background: Digital therapeutic tools (e.g. mobile applications) can be accessible, low-cost interventions that counter misconceptions about medication assisted treatment (MAT) and/or improve deficits in MAT knowledge that are common barriers to treatment entry among individuals with opioid dependence.

Predicting the Effect of Single and Multiple Mutations on Protein Structural Stability.

Predicting how a point mutation alters a protein's stability can guide pharmaceutical drug design initiatives which aim to counter the effects of serious diseases. Conducting mutagenesis studies in physical proteins can give insights about the effects of amino acid substitutions, but such wet-lab work is prohibitive due to the time as well as financial resources needed to assess the effect of even a single amino acid substitution. Computational methods for predicting the effects of a mutation on a protein structure can complement wet-lab work, and varying approaches are available with promising accuracy rates.

Deceased Donor Organ Transplantation Performed in the United States for Noncitizens and Nonresidents.

Since 2012, the Organ Procurement and Transplantation Network (OPTN)/United Network for Organ Sharing (UNOS) has required transplant centers to record the citizenship residency status of patients undergoing transplantation in the United States. This policy replaced the 5% threshold of the non-US citizen/nonresidents (NC/NR) undergoing organ transplantation that could result in an audit of transplant center activity. Since April 1, 2015, the country of residence for the NC/NR on the waitlist has also been recorded.

Genetic Variation in MAP3K1 Associates with Ventilator-Free Days in Acute Respiratory Distress Syndrome.

Mitogen-activated protein kinase kinase kinase 1 (MAP3K1) regulates numerous intracellular signaling pathways involved in inflammation and apoptosis. We hypothesized that genetic variation in MAP3K1 might be associated with outcomes in patients with acute respiratory distress syndrome (ARDS), and that these variants would alter MAP3K1-mediated changes in inflammation and transcriptional regulation. To test this hypothesis, we genotyped single-nucleotide polymorphisms covering linkage disequilibrium bins in MAP3K1 in 306 subjects with ARDS from the ARDSNet FACTT (Fluid and Catheter Treatment Trial) study, and tested for associations between MAP3K1 single-nucleotide polymorphisms and ventilator-free days (VFDs) and mortality.

U1 Adaptors Suppress the Oncogenic Axis in Human Pancreatic Cancer Xenografts.

Targeting KRAS and MYC has been a tremendous challenge in cancer drug development. Genetic studies in mouse models have validated the efficacy of silencing expression of both KRAS and MYC in mutant KRAS-driven tumors. We investigated the therapeutic potential of a new oligonucleotide-mediated gene silencing technology (U1 Adaptor) targeting KRAS and MYC in pancreatic cancer.

Endometrial carcinoma: The perioperative and long-term outcomes of robotic surgery in the morbidly obese.

Background And Methods: To evaluate surgical and pathologic outcomes of robotic assisted versus open hysterectomy for women with at least class II (BMI >35) and class III (BMI >40) obesity with endometrial cancer. Women with endometrial cancer and class II obesity, treated with open or robotic hysterectomy between 3/2005 and 3/2013 were eligible for inclusion in this retrospective cohort. Patients with class III obesity were reviewed both within the cohort of class II and as a separate subset.
