Racial and Ethnic Disparities in Cervical Insufficiency, Cervical Cerclage, and Preterm Birth.

Background: The frequency of cervical insufficiency differs among the major racial and ethnic groups, with limited data specific to Asian American and Native Hawaiian/Pacific Islander (AANHPI) subpopulations. We assessed cervical insufficiency diagnoses and related outcomes across 10 racial and ethnic groups, including disaggregated AANHPI subgroups, in a large population-based cohort. Study Design: We performed a retrospective cohort study of all singleton births between 20-42 weeks' gestation in California from 2007 to 2018. Logistic regression models were performed to estimate the odds of cervical insufficiency and, among people with cervical insufficiency, the odds of cerclage and preterm birth according to self-reported race and ethnicity. Results: Among 5,114,470 births, 38,605 (0.8%) had a diagnosis code for cervical insufficiency. Compared with non-Hispanic White people, non-Hispanic Black people had the highest odds of cervical insufficiency (adjusted odds ratio [aOR] 3.07; 95% confidence interval [CI], 2.97, 3.18), for cerclage placement and higher odds for preterm birth. Disaggregating AANHPI subgroups showed that Indian people had the highest odds (aOR 1.94; 95% CI, 1.82, 2.07) of cervical insufficiency and had significantly higher odds of cerclage without increased odds of preterm birth; Southeast Asian people had the highest odds of preterm birth. Conclusion: Within a large, diverse population-based cohort, non-Hispanic Black people experienced the highest rates of cervical insufficiency, and among those with cervical insufficiency, had among the highest rates of cerclage and preterm birth. Among AANHPI subgroups specifically, Indian people had the highest rates of cervical insufficiency and cerclage placement, without increased rates of preterm birth; Southeast Asian people had the highest rates of preterm birth, without increased rates of cerclage. Disaggregating AANHPI subgroups identifies important differences in obstetric risk factors and outcomes.

Trends in ovarian, fallopian tube, and primary peritoneal cancer incidence, mortality, and survival: A 15-year population-based analysis.

OBJECTIVE: To characterize trends in ovarian, fallopian tube, and primary peritoneal cancer incidence and incidence-based mortality based on histology and site of origin. METHODS: We obtained age-adjusted incidence and incidence-based mortality for patients with ovarian, fallopian tube, and primary peritoneal cancer from 2000 to 2019 from the US SEER 17 database. Joinpoint 4.9.1.0 was used to characterize log-linear time trends. RESULTS: The incidence and incidence-based mortality of all cancers trended down during the study period. The incidence of epithelial cancers decreased from 2004 to 2019 (AAPC -1.2%, p < 0.001), including that of high-grade (2006-2019: APC -1.2%, p < 0.05) and low-grade (2003-2019: APC -2.4%, p < 0.05) epithelial cancers. There was no change in incidence or incidence-based mortality for ovarian stromal and germ cell cancers. CONCLUSION: There has been a decrease in the incidence and incidence-based mortality of ovarian, fallopian tube, and primary peritoneal cancer, primarily due to reductions in advanced stage epithelial cancers originating in the ovary, fallopian tube, or peritoneum.

Technetium Tc 99m tilmanocept fails to detect sentinel lymph nodes in endometrial cancer.

Background: Technetium Tc 99m tilmanocept is a synthetic radiotracer specifically designed for sentinel lymph node (SLN) mapping that has been FDA-approved in breast cancer, melanoma, and head and neck cancer. No published studies exist for the use of this radiotracer in endometrial cancer. Objective: The primary objective was to determine the detection rate of bilateral SLNs in endometrial cancer with the concurrent use of technetium Tc 99m tilmanocept and ICG. Methods: An open-label, single cohort, prospective feasibility study was conducted with participants receiving preoperative cervical injections of technetium Tc 99m tilmanocept followed by subsequent imaging and SPECT/CT. Intraoperative ICG injections were administered for all patients with near-infrared imaging used to visualize lymphatic vessels and nodes. A laparoscopic gamma counter was used to detect radioactive SLN intraoperatively. Results: All six evaluated patients had FIGO grade 1 or 2 endometrioid histology. Stage IA/IB were in 33% and 66% of patients, respectively. Tilmanocept did not map any SLN in the first six patients but instead showed retention of the tracer in the cervical stroma, leading to study discontinuation for futility. ICG mapped bilateral SLN in all patients with the most common location being the external iliac region, followed by the obturator and common iliac areas. All patients had CD206 positive staining throughout the full wall thickness of ectocervix, transformation zone, endocervix, and lymphatic vessels. No patients experienced adverse events. Conclusion: Technetium Tc 99m tilmanocept did not detect SLN in early stage endometrial cancers and is unlikely to improve bilateral detection rate compared to ICG alone. ICG remains a standard technique for SLN detection in low stage, low grade endometrial cancer.

Gender bias in the medical education of obstetrician-gynaecologists in the United States: A systematic review.

BACKGROUND: The number of men entering obstetrics and gynaecology (Ob/Gyn) residencies and general Ob/Gyn practice is decreasing. Gender biases against their participation may affect career decisions. OBJECTIVE: This systematic review examines: (i) female patients' gender preferences and perceptions of men as Ob/Gyns and/or medical students; and (ii) the influence of gender on students' education and career decisions. SEARCH STRATEGY: We identified relevant research via PubMed using variations of three concepts in combination: Ob/Gyn care, gender bias/preference, and medical education or career. We conducted the initial review in 2018 and repeated the search in March 2021, adding additional references via citation review of included research. SELECTION CRITERIA: We restricted the review to original research from the United States between 2000-2021. DATA COLLECTION: Fifteen studies met inclusion criteria, categorised into three groups: (i) patient's gender preference for Ob/Gyns; (ii) patient's gender preference for medical students during the Ob/Gyn clerkship; and (iii) influence of gender bias on Ob/Gyn career decisions. MAIN RESULTS: Patients prioritised their physician's care attributes (eg technical skill, compassion, experience) over gender when choosing Ob/Gyns; however, provider gender was prioritised for medical students. Male medical students more commonly reported exclusion from clinical opportunities, although objective clinical exposure was like that of female counterparts. Despite perceived gender bias, male medical students reported increased Ob/Gyn interest post-clerkship; interest did not translate into residency applications. These findings are limited by study quality and heterogeneity. CONCLUSIONS: Real and perceived gender bias among female patients and male medical students in Ob/Gyn may underlie declining numbers of men entering the field.

Role of sex steroid hormones in pelvic organ prolapse.

OBJECTIVE: Pelvic organ prolapse (POP) affects a significant percentage of women and contributes to major healthcare costs both in the United States and worldwide. This review examines the current understanding of the role of sex steroid hormones (estrogens, androgens, and progesterone) in POP in premenopausal, perimenopausal, and postmenopausal women. METHODS: We reviewed the relevant studies on POP related to estrogens, androgens, and progesterone in both animal models and humans. RESULTS: Estrogen has a profound influence on the synthesis and metabolism of pelvic connective tissues, and may have the ability to both prevent POP and improve prognosis if used therapeutically. There is limited research regarding the role of androgens and progesterone and their receptors in POP and results so far have been contradictory, warranting further study to determine whether changes in androgen and progesterone receptor expression are a cause or effect of POP. CONCLUSIONS: Because of the role that estrogen plays in maintaining the integrity of pelvic floor connective tissues, we propose that rigorous and well-controlled studies are needed on the role of exogenous estrogen administration as a form of POP prevention. : Video Summary:http://links.lww.com/MENO/A583.
