A Lexicon for First-Trimester US: Society of Radiologists in Ultrasound Consensus Conference Recommendations.

The Society of Radiologists in Ultrasound convened a multisociety panel to develop a first-trimester US lexicon based on scientific evidence, societal guidelines, and expert consensus that would be appropriate for imagers, clinicians, and patients. Through a modified Delphi process with consensus of at least 80%, agreement was reached for preferred terms, synonyms, and terms to avoid. An intrauterine pregnancy (IUP) is defined as a pregnancy implanted in a normal location within the uterus.

Ultrasound Evaluation of Uterine Cavity Changes After Stimulation for In Vitro Fertilization.

Objectives: Mock embryo transfer (ET) before in vitro fertilization (IVF) allows for the clinical determination of uterine cavity length (UCL) to optimize embryo placement during clinical ET. Most studies have shown that optimal pregnancy rates occur with clinical ET at a depth of 15 mm from the uterine fundus. In our study, we sought to determine the effect of ovarian stimulation and endometrial preparation on UCL using 2D transabdominal ultrasound.

Inhibition of CSF1R and KIT With Pexidartinib Reduces Inflammatory Signaling and Cell Viability in Endometriosis.

Endometriosis is a common and debilitating disease, affecting ∼170 million women worldwide. Affected patients have limited therapeutic options such as hormonal suppression or surgical excision of the lesions, though therapies are often not completely curative. Targeting receptor tyrosine kinases (RTKs) could provide a nonhormonal treatment option for endometriosis.

Coronavirus Disease 2019 (COVID-19) Vaccination and Assisted Reproduction Outcomes: A Systematic Review and Meta-analysis.

Objective: To assess the association between coronavirus disease 2019 (COVID-19) vaccination and female assisted reproduction outcomes through a systematic review and meta-analysis.

Data Sources: We searched Medline (OVID), EMBASE, Web of Science, Cochrane Library, and ClinicalTrials.gov on January 11, 2023, for original articles on assisted reproduction outcomes after COVID-19 vaccination.

Take your mother's ferry: preimplantation embryo development requires maternal karyopherins for nuclear transport.

The genetic basis of preimplantation embryo arrest is slowly being unraveled. Recent discoveries point to maternally expressed proteins required for cellular functions before the embryonic genome is activated. In this issue of the JCI, Wang, Miyamoto, et al.

Endometrial Abnormalities: Correlation Between Different Diagnostic Modalities.

Objectives: We sought to evaluate the diagnostic accuracy of transvaginal ultrasound (TVUS) saline infusion sonohysterogram (SIS), and hysteroscopy for diagnosing endometrial abnormalities and their correlation with histological findings. In addition, we sought to validate the subsistence of a more subtle abnormality called "redundant endometrium" (RE).

Methods: Retrospective cohort study of patients presenting with infertility and diagnosed with endometrial abnormalities who underwent hysteroscopy and pathology evaluation.

Options for preserving fertility in women undergoing gonadotoxic treatment.

Cancer chemotherapy and radiotherapy can be toxic to the ovaries, but women can improve their chances of preserving their fertility. Three options are available: gonadotropin-releasing hormone (GnRH) analogues, oocyte cryopreservation, and ovarian tissue cryopreservation. A fourth option, ovarian transposition, is valid for patients undergoing pelvic radiation but is not useful in patients undergoing chemotherapy.

Association between redundant endometrium and endometrial polyps: a pilot study.

Background: The aim of this study was to explore the organic features of redundant endometrium (RE), we examined the expression of different endometrial hormone receptors, oncogenes, and cell replication markers, in normal endometrium (NE), endometrial polyps (EP) and RE specimens.

Methods: This was an experimental study examining endometrial tissue expression of estrogen receptors (ER1 and 2), progesterone receptors (PR-A+B), androgen receptor (AR), insulin receptor (Insulin-R), insulin-like growth factor receptor 1 (IGFR-1), thyroid hormone receptor (TH-RB), B-cell lymphoma 2 (Bcl-2), Ki67, HOXA10, in women with NE, EP and RE, of women undergoing hysteroscopy for benign gynecologic pathology. Specimens were separated in 3 groups: NE, EP, RE.

A comparison of four systems for uterine septum diagnosis and indication for surgical correction.

Introduction: Existing guidelines do not settle on a specific length to indicate surgical incision of subseptations because of differences in the four published diagnostic methods: AFS-10 mm classification, 1988/2003, ESHRE-ESGE classification, 2013, ASRM criteria, 2016- and 5.9-mm length cut-off, 2017. With this review and data analysis we sought to identify the classification method with the most accurate association with early pregnancy loss, as to identify a subseptation length cut-off to indicate surgical correction.

Fluid deficit calculation at hysteroscopy: could consideration of intraperitoneal fluid accumulation add insight to safety limits?

Background: The current literature and guidelines are largely silent regarding the contribution of the fallopian tubes to the fluid deficit (FD) during hysteroscopy. We explored whether the FD could be in part due to transtubal passage.

Methods: This was a prospective cohort study.

Anti-Müllerian Hormone (AMH) regulates BRCA1 and BRCA2 gene expression after ovarian cortex transplantation.

Objective: To test whether recombinant anti-Müllerian hormone (rAMH) could exert an inhibitory function on BRCA1/2 expression in human ovarian cortex.

Methods: Pilot study on ovariectomized nude mice xenotransplanted with human vitrified/warmed ovarian cortex and treated with rAMH infusion pump. Twelve nude mice were ovariectomized and Alzet pumps delivering 1.

Recombinant Anti-Müllerian Hormone (rAMH) for Stalling In Vitro Granulosa Cell Replication.

To investigate whether recombinant AMH (rAMH) is able to decrease cellular proliferation/apoptosis in luteinized granulosa cells (GCs) through hormonal regulation, a primary culture of GCs was established from GCs obtained at time of oocyte retrieval from follicular fluid of 3 patients. Cells were seeded in well cell culture plates at a density of 100,000 cells/well in medium and treated with rAMH 20 ng/ml (rAMH group), or phosphate-buffered saline (PBS-control group), for 24 h. Total RNA was extracted from all cells, followed by cDNA synthesis and real-time RT-PCR to quantify the expression levels of AMH, AMH-R2, FSH-R, inhibin B, cell proliferation (Ki67), and apoptosis (Caspase 3).

Restoration of Uterine Cavity Measurements after Surgical Correction.

: We sought to define the uterine and uterine cavity dimensions of subseptate uteri before and after hysteroscopic surgical incision, and compare them to those obtained in normal uteri with 3-D ultrasound. : Two cohorts of consecutive women with normal-appearing uterine cavity and women diagnosed with uterine subseptations, before and after undergoing hysteroscopic incision. 3-D ultrasound was used to measure the uterine cavity width, length, and area on a frozen coronal view of the uterus.

Early detection of velamentous cord insertion at the eighth week of gestation.

Velamentous cord insertion can be diagnosed at 8 weeks of gestation, earlier than previously reported. Fetal surveillance may be informed and prognosis may be impacted by early diagnosis once viability is reached.

Early pregnancy ultrasound measurements and prediction of first trimester pregnancy loss: A logistic model.

Our objective was to prospectively validate the use of gestational sac (GS), yolk sac (YS) diameter, crown-rump length (CRL), and embryonal heart rate (HR) dimensions to identify early pregnancy loss. This was a prospective cohort study of first trimester pregnancies. GS and YS diameter, CRL, and HR measurements were serially obtained in singleton and twin pregnancies from 6 through 10 weeks' gestation.

Lack of Fetal Insulin Resistance in Maternal Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) affects 8-10% of women. NIH criteria for diagnosis include chronic anovulation and evidence of clinical or biochemical hyperandrogenism. PCOS is associated with adverse neonatal outcomes.

Pilot study establishing a nomogram of yolk sac growth during the first trimester of pregnancy.

Aim: The yolk sac (YS) has been reported as a reliable predictor of adverse pregnancy outcomes, however, it has always been evaluated cross-sectionally with a single ultrasound per patient. We sought to validate the use of YS dimensions in serial ultrasounds throughout the first 10 weeks of singleton and multiple gestations.

Methods: This was a prospective cohort study where YS diameters were serially obtained with 2D ultrasound in singleton and multiple gestations from 5 to 11 weeks.

Diagnosis of Placental Position by Early First-Trimester Ultrasound: A Pilot Study.

Objective: Conventional wisdom is that placental location cannot be identified before 8 weeks' gestation when the placenta first becomes hyperechogenic on ultrasound. We sought to evaluate whether placental location could be reliably diagnosed between 5 and 6 weeks' gestation.

Materials And Methods: This was a retrospective analysis of prospectively acquired data.

Serum Anti-Müllerian hormone (AMH) in mothers with polycystic ovary syndrome (PCOS) and their term fetuses.

We sought to determine serum AMH levels in the maternal circulation, and the umbilical artery and vein, in normal women and women with PCOS, and their neonates at time of delivery. This represents a cross-sectional study of 57 pregnant patients who presented to the labor and delivery suite and subsequently delivered. We obtained maternal, as well as fetal blood from both, umbilical artery and vein.

Xenotransplantation of pre-pubertal ovarian cortex and prevention of follicle depletion with anti-Müllerian hormone (AMH).

Objective: To determine whether recombinant AMH (rAMH) could prevent post-transplant follicular depletion by acting on the stemness markers Oct-4, Sox2, and NANOG.

Materials And Methods: This was an experimental study where 12 ovariectomized nude mice were xenotransplanted with vitrified/warmed ovarian cortex obtained from a pre-pubertal girl and Alzet pumps delivering rAMH, or placebo (control), were inserted intra-abdominally. Previously vitrified/warmed ovarian cortex fragments were transplanted after 7 days and then harvested after 14 days from pump placement.
