Labile Heme and Heme Oxygenase-1 Maintain Tumor-Permissive Niche for Endometriosis-Associated Ovarian Cancer.

Endometriosis, a painful gynecological condition accompanied by inflammation in women of reproductive age, is associated with an increased risk of ovarian cancer. We evaluated the role of peritoneal heme accumulated during menstrual cycling, as well as peritoneal and lesional macrophage phenotype, in promoting an oncogenic microenvironment. We quantified the heme-degrading enzyme, heme oxygenase-1 (HO-1, encoded by 1) in normal peritoneum, endometriotic lesions and endometriosis-associated ovarian cancer (EAOC) of clear cell type (OCCC).

The Sonographic Appearance of Endometrial Intraepithelial Neoplasia.

Objectives: To describe the sonographic findings of endometrial intraepithelial neoplasia (EIN), a precursor of endometrial cancer.

Methods: Cases were found by word search of pathology database 1/2013 to 6/2019. One hundred and seventy-eight patients with ultrasound <1 year prior to biopsy were included.

Use of Fundamentals of Laparoscopic Surgery Testing to Assess Gynecologic Surgeons: A Retrospective Cohort Study of 10-Years Experience.

Study Objective: To compare the Fundamentals of Laparoscopic Surgery (FLS) exam scores between obstetrics and gynecology (OBGYN) and general surgery (GS) providers.

Design: This is a retrospective cohort study at a single institution from July 2007 to May 2018. Categorical and continuous variables were analyzed with χ2 test, t test, and Wilcoxon rank sum test.

Essentials in Minimally Invasive Gynecology Manual Skills Construct Validation Trial.

Objective: To establish validity evidence for the Essentials in Minimally Invasive Gynecology laparoscopic and hysteroscopic simulation systems.

Methods: A prospective cohort study was IRB approved and conducted at 15 sites in the United States and Canada. The four participant cohorts based on training status were: 1) novice (postgraduate year [PGY]-1) residents, 2) mid-level (PGY-3) residents, 3) proficient (American Board of Obstetrics and Gynecology [ABOG]-certified specialists without subspecialty training); and 4) expert (ABOG-certified obstetrician-gynecologists who had completed a 2-year fellowship in minimally invasive gynecologic surgery).

Impact of prior hysterectomy on surgical outcomes for laparoscopic adnexal surgery.

Background: Adnexal surgery is believed to be more complex in patients with prior hysterectomy; however, there is little data regarding surgical outcomes. Understanding of individualized risks improves counseling, informed consent, and preoperative planning.

Methods: We performed a retrospective cohort study with a control group; we evaluated 744 patients undergoing laparoscopic adnexal surgery at an academic tertiary care center from 2011 to 2015.

Hysterectomy Practice Patterns in the Postmorcellation Era.

Objective: To characterize long-term national trends in surgical approach for hysterectomy after the U.S. Food and Drug Administration (FDA) warning against power morcellation for laparoscopic specimen removal.

Incidence of Venous Thromboembolism After Different Modes of Gynecologic Surgery.

Objective: To evaluate the incidence of postoperative venous thromboembolism after gynecologic surgery by mode of incision.

Methods: We conducted a retrospective cohort study of all patients who underwent gynecologic surgery from May 2006 to June 2015 at two tertiary care academic hospitals in Massachusetts. Billing and diagnosis codes were used to identify surgeries and cases of venous thromboembolism.

Venous Thromboembolism in Minimally Invasive Gynecologic Surgery: A Systematic Review.

Venous thromboembolism (VTE) is the leading cause of preventable healthcare-related death after surgery. Although there is a large body of research on VTE in the general population as well as risk-assessment tools, evidence specific to the current practices in gynecologic surgery is more sparse. This review article seeks to discuss current literature on VTE in gynecologic surgery, with a focus on minimally invasive surgery.

Occult Gynecologic Cancer in Women Undergoing Hysterectomy or Myomectomy for Benign Indications.

Objective: To estimate the prevalence of corpus uteri, cervix uteri, and ovarian malignancy in women undergoing hysterectomy or myomectomy for presumed benign indications.

Methods: We conducted a secondary analysis of data from the 2014-2015 American College of Surgeons National Surgical Quality Improvement Program. Adult women undergoing hysterectomies and myomectomies without evidence for known or suspected cancer at the beginning of surgery were identified from the database.

Vulvar Lesions in an 8-Year-Old Girl: Cutaneous Manifestations of Multisystem Langerhans Cell Histiocytosis.

Background: Langerhans cell histiocytosis (LCH) is a rare localized or systemic disease characterized by proliferation of myeloid-derived dendritic cells. Vulvar lesions might be the herald symptom of LCH and might mimic other cutaneous lesions. Prognosis varies widely on the basis of the extent and spread of disease.

Review of Sterilization Techniques and Clinical Updates.

Sterilization is the most common form of contraception used worldwide and is highly effective in preventing unintended pregnancy. Each of the available sterilization methods has unique advantages and disadvantages that influence the choice of approach for each individual patient. Salpingectomy for sterilization has become more popular in recent years, with mounting evidence suggesting a protective effect against ovarian cancers originating in the fallopian tube.

Preferential epigenetic programming of estrogen response after in utero xenoestrogen (bisphenol-A) exposure.

Bisphenol-A (BPA) is an environmentally ubiquitous estrogen-like endocrine-disrupting compound. Exposure to BPA in utero has been linked to female reproductive disorders, including endometrial hyperplasia and breast cancer. Estrogens are an etiological factor in many of these conditions.

A novel role for the AAA ATPase spastin as a HOXA10 transcriptional corepressor in Ishikawa endometrial cells.

Homeobox A10 (HOXA10), a transcription factor required for uterine development and embryo receptivity, functions downstream of estrogen and progesterone in uterine endometrium. HOXA10 represses endometrial expression of empty spiracles homeobox 2 (EMX2), the human ortholog of Drosophila empty spiracles. The ATPases associated with various cellular activities (AAA) ATPase spastin has a well-characterized role in neurotransmitter trafficking.

Cigarette smoke increases progesterone receptor and homeobox A10 expression in human endometrium and endometrial cells: a potential role in the decreased prevalence of endometrial pathology in smokers.

Cigarette smoking has long been tied to a multitude of poor health outcomes; however, in reproductive biology, smoking has shown several unintuitive findings. Smoking is associated with significantly decreased rates of endometriosis and endometrial cancer. Here, we show that treatment with cigarette smoke extract leads to increased mRNA and protein expression of homeobox A10 (HOXA10) and progesterone receptor (PGR) as well as more rapid decidualization of endometrial stromal cells in vitro.

A novel mutation of HOXA13 in a family with hand-foot-genital syndrome and the role of polyalanine expansions in the spectrum of Müllerian fusion anomalies.

Objective: To report a novel mutation found in a family with hand-foot-genital syndrome (HFGS). To characterize the genetic basis of true HFGS versus presence of non-HFGS-related uterovaginal septa.

Design: Case-control study.

Oct-1 and nuclear factor Y bind to the SURG-1 element to direct basal and gonadotropin-releasing hormone (GnRH)-stimulated mouse GnRH receptor gene transcription.

The cis-regulatory element localized to position -292/-285 of the mouse GnRH receptor (mGnRHR) gene promoter, designated Sequence Underlying Responsiveness to GnRH 1 (SURG-1), has been shown previously to contribute to stimulation of mGnRHR gene expression by GnRH. We have identified three specific protein-DNA complexes on the SURG-1 element by EMSA using nuclear extracts from the gonadotrope-derived alphaT3-1 and LbetaT2 cell lines. Serial mutagenesis and supershift assays identified nuclear factor Y (NF-Y) binding to -288/-284 and Oct-1 binding to a TAAT sequence at -290/-287.
