FBXO44 promotes DNA replication-coupled repetitive element silencing in cancer cells.

Repetitive elements (REs) compose ∼50% of the human genome and are normally transcriptionally silenced, although the mechanism has remained elusive. Through an RNAi screen, we identified FBXO44 as an essential repressor of REs in cancer cells. FBXO44 bound H3K9me3-modified nucleosomes at the replication fork and recruited SUV39H1, CRL4, and Mi-2/NuRD to transcriptionally silence REs post-DNA replication. FBXO44/SUV39H1 inhibition reactivated REs, leading to DNA replication stress and stimulation of MAVS/STING antiviral pathways and interferon (IFN) signaling in cancer cells to promote decreased tumorigenicity, increased immunogenicity, and enhanced immunotherapy response. FBXO44 expression inversely correlated with replication stress, antiviral pathways, IFN signaling, and cytotoxic T cell infiltration in human cancers, while a FBXO44-immune gene signature correlated with improved immunotherapy response in cancer patients. FBXO44/SUV39H1 were dispensable in normal cells. Collectively, FBXO44/SUV39H1 are crucial repressors of RE transcription, and their inhibition selectively induces DNA replication stress and viral mimicry in cancer cells.

Nuclear pore complex-mediated modulation of TCR signaling is required for naïve CD4+ T cell homeostasis.

Nuclear pore complexes (NPCs) are channels connecting the nucleus with the cytoplasm. We report that loss of the tissue-specific NPC component Nup210 causes a severe deficit of naïve CD4+ T cells. Nup210-deficient CD4+ T lymphocytes develop normally but fail to survive in the periphery. The decreased survival results from both an impaired ability to transmit tonic T cell receptor (TCR) signals and increased levels of Fas, which sensitize Nup210-/- naïve CD4+ T cells to Fas-mediated cell death. Mechanistically, Nup210 regulates these processes by modulating the expression of Cav2 (encoding Caveolin-2) and Jun at the nuclear periphery. Whereas the TCR-dependent and CD4+ T cell-specific upregulation of Cav2 is critical for proximal TCR signaling, cJun expression is required for STAT3-dependent repression of Fas. Our results uncover an unexpected role for Nup210 as a cell-intrinsic regulator of TCR signaling and T cell homeostasis and expose NPCs as key players in the adaptive immune system.

PSGL-1 Is an Immune Checkpoint Regulator that Promotes T Cell Exhaustion.

Chronic viruses and cancers thwart immune responses in humans by inducing T cell dysfunction. Using a murine chronic virus that models human infections, we investigated the function of the adhesion molecule, P-selectin glycoprotein ligand-1 (PSGL-1), that is upregulated on responding T cells. PSGL-1-deficient mice cleared the virus due to increased intrinsic survival of multifunctional effector T cells that had downregulated PD-1 as well as other inhibitory receptors. Notably, this response resulted in CD4(+)-T-cell-dependent immunopathology. Mechanistically, PSGL-1 ligation on exhausted CD8(+) T cells inhibited T cell receptor (TCR) and interleukin-2 (IL-2) signaling and upregulated PD-1, leading to diminished survival with TCR stimulation. In models of melanoma cancer in which T cell dysfunction occurs, PSGL-1 deficiency led to PD-1 downregulation, improved T cell responses, and tumor control. Thus, PSGL-1 plays a fundamental role in balancing viral control and immunopathology and also functions to regulate T cell responses in the tumor microenvironment.

MicroRNA-139 Expression Is Dispensable for the Generation of Influenza-Specific CD8+ T Cell Responses.

MicroRNAs (miRNAs/miRs) are small, endogenous noncoding RNAs that are important post-transcriptional regulators with clear roles in the development of the immune system and immune responses. Using miRNA microarray profiling, we characterized the expression profile of naive and in vivo generated murine effector antiviral CD8+ T cells. We observed that out of 362 measurable mature miRNAs, 120 were differentially expressed by at least 2-fold in influenza-specific effector CD8+ CTLs compared with naive CD8+ T cells. One miRNA found to be highly downregulated on both strands in effector CTLs was miR-139. Because previous studies have indicated a role for miR-139-mediated regulation of CTL effector responses, we hypothesized that deletion of miR-139 would enhance antiviral CTL responses during influenza virus infection. We generated miR-139-/- mice or overexpressed miR-139 in T cells to assess the functional contribution of miR-139 expression in CD8+ T cell responses. Our study demonstrates that the development of naive T cells and generation or differentiation of effector or memory CD8+ T cell responses to influenza virus infection are not impacted by miR-139 deficiency or overexpression; yet, miR-139-/- CD8+ T cells are outcompeted by wild-type CD8+ T cells in a competition setting and demonstrate reduced responses to Listeria monocytogenes Using an in vitro model of T cell exhaustion, we confirmed that miR-139 expression similarly does not impact the development of T cell exhaustion. We conclude that despite significant downregulation of miR-139 following in vivo and in vitro activation, miR-139 expression is dispensable for influenza-specific CTL responses.

Linzagolix with and without hormonal add-back therapy for the treatment of symptomatic uterine fibroids: two randomised, placebo-controlled, phase 3 trials.

BACKGROUND: Uterine fibroids are common non-cancerous neoplasm that cause heavy menstrual bleeding and other signs. Linzagolix is an oral gonadotropin-releasing hormone receptor antagonist taken once per day that dose-dependently suppresses gonadal steroids and might reduce uterine-fibroid-associated signs. Two phase 3 trials were conducted to confirm the efficacy and safety of linzagolix at full-suppression (200 mg) and partial-suppression (100 mg) doses with or without hormonal add-back therapy (1 mg oestradiol and 0·5 mg norethisterone acetate) compared with placebo for the treatment of symptomatic uterine fibroids. METHODS: PRIMROSE 1 and PRIMROSE 2 were identical 52-week, randomised, parallel, double-blind, placebo-controlled, phase 3 trials conducted at clinics in the USA (PRIMROSE 1) and Europe and the USA (PRIMROSE 2). Eligible women with uterine fibroid-associated heavy menstrual bleeding (menstrual blood loss >80 mL per cycle) were randomly assigned in a 1:1:1:1:1 ratio to one of five masked treatments: (1) placebo, (2) 100 mg linzagolix per day alone, (3) 100 mg linzagolix per day with once-per-day hormonal add-back therapy (1 mg oestradiol and 0·5 mg norethisterone acetate), (4) 200 mg linzagolix per day alone, or (5) 200 mg linzagolix per day with once-per-day hormonal add-back therapy (1 mg oestradiol and 0·5 mg norethisterone acetate). The primary endpoint was a response (menstrual blood loss ≤80 mL and ≥50% reduction from baseline) at 24 weeks in women who received at least one dose of treatment and did not meet any exclusion criteria based on predosing assessments. These trials are registered with ClinicalTrials.gov (NCT03070899 and NCT03070951). The trials have been completed. FINDINGS: Between May, 2017, and October, 2020, in PRIMROSE 1, 574 women were enrolled, of which 48 discontinued and 15 were excluded; therefore, 511 women were included in the full analysis set; and in PRIMROSE 2, 535 women were enrolled, of which 24 did not receive the study drug and ten women were excluded from the study, resulting in 501 women being included in the full analysis set. In both trials, a significantly higher proportion of women had a reduction in heavy menstrual bleeding in all linzagolix (with or without add-back therapy) treatment groups compared with the placebo group (p≤0·003). In PRIMROSE 1, the response rates were 56·4% (95% CI 45·8-66·6%) in the 100 mg group, 66·4% (56·6-75·2%) in the 100 mg plus add-back therapy group, 71·4% (61·8-79·8%) in the 200 mg group, and 75·5% (66·0-83·5%) in the 200 mg plus add-back therapy group, compared with 35·0% (25·8-45·0%) in the placebo group. In PRIMROSE 2, the response rates were 56·7% (46·3-66·7%) in the 100 mg group, 77·2% (67·8-85·0%) in the 100 mg plus add-back therapy group, 77·7% (68·4-85·3%) in the 200 mg group, and 93·9% (87·1-97·7%) in the 200 mg plus add-back therapy group, compared with 29·4% (20·8-39·3%) with placebo. The most common adverse events up to 24 weeks were hot flushes (35% of participants in PRIMROSE 1 and 32% in PRIMROSE 2 with linzagolix [200 mg] alone and 3-14% in all other groups). INTERPRETATION: Linzagolix (100 mg or 200 mg) with or without add-back therapy significantly reduced heavy menstrual bleeding. Partial suppression with once-per-day linzagolix (100 mg) without add-back therapy potentially provides a unique option for the chronic treatment of symptomatic uterine fibroids in women who cannot or do not want to take concomitant hormonal add-back therapy.

Elagolix for Heavy Menstrual Bleeding in Women with Uterine Fibroids.

BACKGROUND: Uterine fibroids are hormone-responsive neoplasms that are associated with heavy menstrual bleeding. Elagolix, an oral gonadotropin-releasing hormone antagonist resulting in rapid, reversible suppression of ovarian sex hormones, may reduce fibroid-associated bleeding. METHODS: We conducted two identical, double-blind, randomized, placebo-controlled, 6-month phase 3 trials (Elaris Uterine Fibroids 1 and 2 [UF-1 and UF-2]) to evaluate the efficacy and safety of elagolix at a dose of 300 mg twice daily with hormonal "add-back" therapy (to replace reduced levels of endogenous hormones; in this case, estradiol, 1 mg, and norethindrone acetate, 0.5 mg, once daily) in women with fibroid-associated bleeding. An elagolix-alone group was included to assess the impact of add-back therapy on the hypoestrogenic effects of elagolix. The primary end point was menstrual blood loss of less than 80 ml during the final month of treatment and at least a 50% reduction in menstrual blood loss from baseline to the final month; missing data were imputed with the use of multiple imputation. RESULTS: A total of 412 women in UF-1 and 378 women in UF-2 underwent randomization, received elagolix or placebo, and were included in the analyses. Criteria for the primary end point were met in 68.5% of 206 women in UF-1 and in 76.5% of 189 women in UF-2 who received elagolix plus add-back therapy, as compared with 8.7% of 102 women and 10% of 94 women, respectively, who received placebo (P<0.001 for both trials). Among the women who received elagolix alone, the primary end point was met in 84.1% of 104 women in UF-1 and in 77% of 95 women in UF-2. Hot flushes (in both trials) and metrorrhagia (in UF-1) occurred significantly more commonly with elagolix plus add-back therapy than with placebo. Hypoestrogenic effects of elagolix, especially decreases in bone mineral density, were attenuated with add-back therapy. CONCLUSIONS: Elagolix with add-back therapy was effective in reducing heavy menstrual bleeding in women with uterine fibroids.

Induction of the activating transcription factor-4 in the intratumoral CD8+ T cells sustains their viability and anti-tumor activities.

Immune suppressive factors of the tumor microenvironment (TME) undermine viability and exhaust the activities of the intratumoral cytotoxic CD8 + T lymphocytes (CTL) thereby evading anti-tumor immunity and decreasing the benefits of immune therapies. To counteract this suppression and improve the efficacy of therapeutic regimens, it is important to identify and understand the critical regulators within CD8 + T cells that respond to TME stress and tumor-derived factors. Here we investigated the regulation and importance of activating transcription factor-4 (ATF4) in CTL using a novel Atf4ΔCD8 mouse model lacking ATF4 specifically in CD8 + cells. Induction of ATF4 in CD8 + T cells occurred in response to antigenic stimulation and was further increased by exposure to tumor-derived factors and TME conditions. Under these conditions, ATF4 played a critical role in the maintenance of survival and activities of CD8 + T cells. Conversely, selective ablation of ATF4 in CD8 + T cells in mice rendered these Atf4ΔCD8 hosts prone to accelerated growth of implanted tumors. Intratumoral ATF4-deficient CD8 + T cells were under-represented compared to wild-type counterparts and exhibited impaired activation and increased apoptosis. These findings identify ATF4 as an important regulator of viability and activity of CD8 + T cells in the TME and argue for caution in using agents that could undermine these functions of ATF4 for anti-cancer therapies.

The Impact of Fertility Goals on Long-term Quality of Life in Reproductive-aged Women Who Underwent Myomectomy versus Hysterectomy for Uterine Fibroids.

STUDY OBJECTIVE: The objective of this study is to compare quality of life (QOL) for myomectomy with hysterectomy 1 to 5 years after surgical management for fibroids. This study evaluated the difference in QOL in a population of women of reproductive age, including those who desire fertility. DESIGN: A retrospective cohort study. INTERVENTIONS: Not applicable. SETTING: A large academic hospital. PATIENTS: A total of 142 women who underwent hysterectomy or myomectomy in 2015 to 2020. Included patients were women aged 18 years or older who underwent surgical intervention owing to uterine fibroids. MEASUREMENTS AND MAIN RESULTS: The 36-Item Short Form Health Survey (SF-36) provides a total score as a single measure of health-related QOL. The Uterine Fibroid Symptom Quality of Life Questionnaire for Hysterectomy and Myomectomy (UFS-QOL) is a patient-reported outcome measure of fibroid symptoms and health-related QOL after hysterectomy and myomectomy. There was no significant difference in SF-36 QOL scores in women after myomectomy who desired fertility compared with those who did not desire fertility, except in the social functioning domain (p = .025). UFS-QOL scores in women after myomectomy who desired fertility were not significantly different compared with women after myomectomy who did not desire fertility (p = .37). There were no significant differences between women who underwent myomectomy and hysterectomy in overall QOL scores on the SF-36 (p = .13) and UFS-QOL scores (p = .16). CONCLUSION: Myomectomy is not associated with significant differences in measures of general health and QOL compared with hysterectomy, making it a viable fibroid management option for women who desire fertility. Our study highlights the importance of discussing fertility goals and QOL when counseling patients for surgical fibroid treatment.

Racial and ethnic disparities in surgical care for endometriosis across the United States.

BACKGROUND: Despite an estimated 10% prevalence of endometriosis among reproductive-age women, surgical population-based data are limited. OBJECTIVE: We sought to investigate racial and ethnic disparities in surgical interventions and complications among patients undergoing endometriosis surgery across the United States. STUDY DESIGN: We performed a retrospective cohort study of American College of Surgeons National Surgical Quality Improvement Program data from 2010 to 2018 identifying International Classification of Diseases, Ninth/Tenth Revision codes for endometriosis We compared procedures, surgical routes (laparoscopy vs laparotomy), and 30-day postoperative complications by race and ethnicity. RESULTS: We identified 11,936 patients who underwent surgery for endometriosis (65% White, 8.2% Hispanic, 7.3% Black or African American, 6.2% Asian, 1.0% Native Hawaiian or Pacific Islander, 0.6% American Indian or Alaska Native, and 11.5% of unknown race). Perioperative complications occurred in 9.6% of cases. After adjusting for confounders, being Hispanic (adjusted odds ratio, 1.31; 95% confidence interval, 1.06-1.64), Black or African American (adjusted odds ratio, 1.71; confidence interval, 1.39-2.10), Native Hawaiian or Pacific Islander (adjusted odds ratio, 2.08; confidence interval, 1.28-3.37), or American Indian or Alaska Native (adjusted odds ratio, 2.34; confidence interval, 1.32-4.17) was associated with surgical complications. Hysterectomies among Hispanic (adjusted odds ratio, 1.68; confidence interval, 1.38-2.06), Black or African American (adjusted odds ratio, 1.77; confidence interval, 1.43-2.18), Asian (adjusted odds ratio, 1.87; confidence interval, 1.43-2.46), Native Hawaiian or Pacific Islander (adjusted odds ratio, 4.16; confidence interval, 2.14-8.10), and patients of unknown race or ethnicity (adjusted odds ratio, 2.07; confidence interval, 1.75-2.47) were more likely to be open. Being Hispanic (adjusted odds ratio, 1.64; confidence interval, 1.16-2.30) or Black or African American (adjusted odds ratio, 2.64; confidence interval, 1.95-3.58) was also associated with receipt of laparotomy for nonhysterectomy procedures. The likelihood of undergoing oophorectomy was increased for Hispanic and Black women (adjusted odds ratio, 2.57; confidence interval, 1.96-3.37 and adjusted odds ratio, 2.06; confidence interval, 1.51-2.80, respectively), especially at younger ages. CONCLUSION: Race and ethnicity were independently associated with surgical care for endometriosis, with elevated complication rates experienced by Hispanic, Black or African American, Native Hawaiian or Pacific Islander, and American Indian or Alaska Native patients.

International Consensus Statement for Recommended Terminology Describing Hysteroscopic Procedures.

OBJECTIVE: To develop a consensus statement of recommended terminology to use for describing different aspects of hysteroscopic procedures that can be uniformly used in clinical practice and research. DESIGN: Open forum discussion followed by online video meetings. SETTING: International community of hysteroscopy experts PATIENTS: Not applicable. INTERVENTIONS: Series of online video meetings to complete a previously established agenda until a final agreement for standardized nomenclature was obtained. MEASUREMENT AND MAIN RESULTS: The adoption and implementation of a common terminology to standardize reporting of hysteroscopic procedures was proposed to cover five domains: pain management, healthcare setting, model of care, type of hysteroscopic procedure and the hysteroscopic approach to the uterine cavity. A final agreement was obtained after 3 online video meetings. CONCLUSION: Hysteroscopy is the gold standard technique for the evaluation and management of uterine disorders. A clear definition and understanding of the terminology used to describe hysteroscopic procedures is lacking. The production of this international consensus statement for terminology to describe hysteroscopic procedures, covering pain management, setting, model of care, type of procedure and hysteroscopic approach, has the potential to enable more effective communication for both clinical and research purposes with the ultimate aim of improving patient care and clinical outcomes.

Faith Community Nurses Making a Difference for Older African Americans in a Pandemic.

ABSTRACT: During and after COVID-19, African Americans experienced a disparate amount of social isolation and loneliness and subsequent increases in morbidity and mortality. Faith community nurses are equipped to assist community providers, health practitioners, and local officials in addressing gaps in older African Americans' financial, social, physical, and spiritual needs during social distancing.

Predictors of response for elagolix with add-back therapy in women with heavy menstrual bleeding associated with uterine fibroids.

BACKGROUND: Uterine fibroids are one of the most common neoplasms found among women globally, with a prevalence of approximately 11 million women in the United States alone. The morbidity of this common disease is significant because it is the leading cause of hysterectomy and causes significant functional impairment for women of reproductive age. Factors including age, body mass index, race, ethnicity, menstrual blood loss, fibroid location, and uterine and fibroid volume influence the incidence of fibroids and severity of symptoms. Elagolix is an oral gonadotropin-releasing hormone receptor antagonist that competitively inhibits pituitary gonadotropin-releasing hormone receptor activity and suppresses the release of gonadotropins from the pituitary gland, resulting in dose-dependent suppression of ovarian sex hormones, follicular growth, and ovulation. In Elaris Uterine Fibroids 1 and Uterine Fibroids 2, 2 replicate multicenter, double-blind, randomized, placebo-controlled, phase 3 studies, treatment of premenopausal women with elagolix with hormonal add-back therapy demonstrated reduction in heavy menstrual bleeding associated with uterine fibroids. OBJECTIVE: This analysis aimed to evaluate the safety and efficacy of elagolix (300 mg twice a day) with add-back therapy (1 mg estradiol/0.5 mg norethindrone acetate once a day) in reducing heavy menstrual bleeding associated with uterine fibroids in various subgroups of women over 6 months of treatment. STUDY DESIGN: Data were pooled from Elaris Uterine Fibroid-1 and Uterine Fibroid-2 studies, which evaluated premenopausal women (18-51 years) with heavy menstrual bleeding (>80 mL menstrual blood loss per cycle, alkaline hematin methodology) and ultrasound-confirmed uterine fibroid diagnosis. Subgroups analyzed included age, body mass index, race, ethnicity, baseline menstrual blood loss, fibroid location, and uterine and primary fibroid volume (largest fibroid identified by ultrasound). The primary endpoint was the proportion of women with <80 mL menstrual blood loss during the final month and ≥50% menstrual blood loss reduction from baseline to final month. Secondary and other efficacy endpoints included mean change in menstrual blood loss from baseline to final month, amenorrhea, symptom severity, and health-related quality of life. Adverse events and other safety endpoints were monitored. RESULTS: The overall pooled Elaris Uterine Fibroid-1 and Uterine Fibroid-2 population was typical of women with fibroids, with a mean age of 42.4 (standard deviation, 5.4) years and a mean body mass index of 33.6 (standard deviation, 7.3) kg/m2 and 67.6% of participants being black or African American women. A wide range of baseline uterine and fibroid volumes and menstrual blood loss were also represented in the overall pooled study population. In all subgroups, the proportion of responders to the primary endpoint, mean change in menstrual blood loss, amenorrhea, reduction in symptom severity, and improvement in health-related quality of life were clinically meaningfully greater for women who received elagolix with add-back therapy than those who received placebo and consistent with the overall pooled study population for the primary endpoint (72.2% vs 9.3%), mean change in menstrual blood loss (-172.5 mL vs -0.8 mL), amenorrhea (50.4% vs 4.5%), symptom severity (-37.1 vs -9.2), and health-related quality of life score (39.9 vs 8.9). Adverse events by subgroup were consistent with the overall pooled study population. CONCLUSION: Elagolix with hormonal add-back therapy was effective in reducing heavy menstrual bleeding associated with uterine fibroids independent of age, body mass index, race, ethnicity, baseline menstrual blood loss, fibroid location, and uterine and primary fibroid volume.

PSGL-1: A New Player in the Immune Checkpoint Landscape.

P-selectin glycoprotein ligand-1 (PSGL-1) has long been studied as an adhesion molecule involved in immune cell trafficking and is recognized as a regulator of many facets of immune responses by myeloid cells. PSGL-1 also regulates T cell migration during homeostasis and inflammatory settings. However, recent findings indicate that PSGL-1 can also negatively regulate T cell function. Because T cell differentiation is finely tuned by multiple positive and negative regulatory signals that appropriately scale the magnitude of the immune response, PSGL-1 has emerged as an important checkpoint during this process. We summarize what is known regarding PSGL-1 structure and function and highlight how it may act as an immune checkpoint inhibitor in T cells.

Fucosyltransferase Induction during Influenza Virus Infection Is Required for the Generation of Functional Memory CD4+ T Cells.

T cells mediating influenza viral control are instructed in lymphoid and nonlymphoid tissues to differentiate into memory T cells that confer protective immunity. The mechanisms by which influenza virus-specific memory CD4+ T cells arise have been attributed to changes in transcription factors, cytokines and cytokine receptors, and metabolic programming. The molecules involved in these biosynthetic pathways, including proteins and lipids, are modified to varying degrees of glycosylation, fucosylation, sialation, and sulfation, which can alter their function. It is currently unknown how the glycome enzymatic machinery regulates CD4+ T cell effector and memory differentiation. In a murine model of influenza virus infection, we found that fucosyltransferase enzymatic activity was induced in effector and memory CD4+ T cells. Using CD4+ T cells deficient in the Fut4/7 enzymes that are expressed only in hematopoietic cells, we found decreased frequencies of effector cells with reduced expression of T-bet and NKG2A/C/E in the lungs during primary infection. Furthermore, Fut4/7-/- effector CD4+ T cells had reduced survival with no difference in proliferation or capacity for effector function. Although Fut4/7-/- CD4+ T cells seeded the memory pool after primary infection, they failed to form tissue-resident cells, were dysfunctional, and were unable to re-expand after secondary infection. Our findings highlight an important regulatory axis mediated by cell-intrinsic fucosyltransferase activity in CD4+ T cell effectors that ensure the development of functional memory CD4+ T cells.

CD44 regulates survival and memory development in Th1 cells.

Optimal immunity to microorganisms depends upon the regulated death of clonally expanded effector cells and the survival of a cohort of cells that become memory cells. After activation of naive T cells, CD44, a widely expressed receptor for extracellular matrix components, is upregulated. High expression of CD44 remains on memory cells and despite its wide usage as a "memory marker," its function is unknown. Here we report that CD44 was essential for the generation of memory T helper 1 (Th1) cells by promoting effector cell survival. This dependency was not found in Th2, Th17, or CD8(+) T cells despite similar expression of CD44 and the absence of splice variants in all subsets. CD44 limited Fas-mediated death in Th1 cells and its ligation engaged the phosphoinositide 3-kinase-Akt kinase signaling pathway that regulates cell survival. The difference in CD44-regulated apoptosis resistance in T cell subpopulations has important implications in a broad spectrum of diseases.

Workplace Harassment and Discrimination in Gynecology: Results of the AAGL Member Survey.

STUDY OBJECTIVE: To characterize workplace and sexual harassment and discrimination among physicians in gynecology. DESIGN: A beta-tested Internet survey was distributed by e-mail using the REDCap platform. All responses were anonymous. SETTING: The survey was distributed to the 7026 physician members of an international gynecologic society (AAGL), including faculty and trainees. PATIENTS: Not applicable. INTERVENTIONS: The survey was distributed on 3 occasions between July and September 2018. The survey contained questions on demographics, attitudes, experiences, and sequelae regarding harassment and discrimination in the workplace. Frequency distributions and nonparametric tests were performed to determine the percentages and types of harassment and discrimination among respondents. MEASUREMENTS AND MAIN RESULTS: A total of 907 physicians responded, including 603 US physicians and 304 non-US physicians; 59% identified as female and 40% as male, and 20% were trainees. Females were more likely than males to think the #MeToo movement was "justified and overdue" (p < .05), independent of age or trainee status. More females than males reported experiencing workplace discrimination (67% vs 39%; p < .001); gender-based discrimination was the most common basis for both. Females indicated decreased self-confidence and lower salary; males indicated fewer employment opportunities and lower patient volume. Harassment was reported by more females than males (53% vs 17%; p < .001), including sexual harassment (39% vs 11%, p <.05). Most experienced loss of self-confidence, felt the offender was in a position of power, and did not report the incident, often due to fear of reprisal. Multiple respondents experienced workplace-related sexual assault. CONCLUSION: Workplace harassment and discrimination are commonly experienced by female and male gynecologists and are usually related to a power differential. Improvements must be made in the workplace environment to achieve equity and a safe workplace free of harassment and discrimination.

Treatment of mucopolysaccharidosis type II (Hunter syndrome): results from a systematic evidence review.

PurposeA pilot systematic evidence review to establish methodology utility in rare genetic diseases, support clinical recommendations, and identify important knowledge gaps.MethodsBroad-based published/gray-literature searches through December 2015 for studies of males with confirmed mucopolysaccharidosis type II (any age, phenotype, genotype, family history) treated with enzyme replacement therapy or hematopoietic stem cell transplantation. Preset inclusion criteria employed for abstract and full document selection, and standardized methods for data extraction and assessment of quality and strength of evidence.ResultsTwelve outcomes reported included benefits of urinary glycosaminoglycan and liver/spleen volume reductions and harms of immunoglobulin G/neutralizing antibody development (moderate strength of evidence). Less clear were benefits of improved 6-minute walk tests, height, early treatment, and harms of other adverse reactions (low strength of evidence). Benefits and harms of other outcomes were unclear (insufficient strength of evidence). Current benefits and harms of hematopoietic stem cell transplantation are unclear, based on dated, low-quality studies. A critical knowledge gap is long-term outcomes. Consensus on selection of critical outcomes and measures is needed to definitively evaluate treatment safety and effectiveness.ConclusionMinor methodology modifications and a focus on critical evidence can reduce review time and resources. Summarized evidence was sufficient to support guidance development and highlight important knowledge gaps.

Hysteroscopy for Abnormal Uterine Bleeding and Fibroids.

Operative hysteroscopy is a safe and effective minimally invasive treatment option for submucosal and intramural leiomyomas. We discuss preoperative evaluation, fluid management, postoperative complications, preventative measures, and hysteroscopic outcomes. Technical instructions and tips for successful hysteroscopy, as well as the various equipment options most commonly utilized in the United States, are also reviewed.
