Introduction: Mirvetuximab soravtansine (MIRV) recently emerged as a promising therapeutic option for patients with platinum resistant ovarian cancer (PROC). In trials leading up to its approval, several ocular and other toxicities were identified. We report our experience with MIRV in a less-selected "real-world" population.

Introduction: Vaginal cancer is a rare yet aggressive cancer, with unmet need for novel therapeutics.

Case Presentation: In this case report, we present a patient with advanced stage, HPV-positive vaginal cancer who demonstrated clinical, radiological, and molecular response to combination treatment of antibody-drug conjugate enfortumab vedotin (EV) with pembrolizumab.

Conclusion: This is the first reported response to this combination therapy in vaginal cancer in the literature.

Introduction: Atypical polypoid adenomyoma (APA) has classically been described as a benign lesion of the endometrium; however, recent studies have identified risk of progression to malignant pathology. Standard treatment includes hysterectomy but since many patients with APA are young and desire fertility, uterine-sparing options have been explored. In this study, we examine long-term outcomes of fertility-sparing treatment, including hysteroscopic resection and progesterone therapy, on progression to hyperplasia or endometrial carcinoma.

Background: Many patients first learn of a pregnancy in the emergency department (ED). However, limited ED physician knowledge in pregnancy disclosure and options counseling may contribute to challenges in patient care and potential missed opportunities for timely access to reproductive care. No standardized instruments exist to teach or assess this important communication skill for the ED physicians.

Objective: Male permanent contraception (PC), that is, vasectomy, is an effective way of preventing pregnancy. In the United States, male PC use has historically been concentrated among higher-educated/higher-income males of White race. In the last decade, use of long-acting reversible contraception (LARC) has increased dramatically.

In January 2023, the Food & Drug Administration modified the Risk Evaluation and Mitigation Strategy program regulating mifepristone to allow direct dispensation from retail pharmacies. In June 2023, we conducted a random, distributive survey of pharmacies in California using secret shopper methodology to investigate the feasibility of accessing mifepristone. One pharmacy had mifepristone immediately available (<24 hours), and misoprostol availability was limited.

Objective: Aberrant β-catenin distribution has been theorized as a predictive biomarker for recurrence in early stage, low grade endometrioid endometrial cancer.

Methods: This retrospective single-institution cohort study reviewed 410 patients with endometrial cancer from May 2018 to May 2022. Only endometrioid histology was included.

Purpose: To assess the impact of elevated BMI on the success of modified natural cycle frozen embryo transfers (mNC-FET) of euploid embryos.

Methods: This retrospective cohort study at a single academic institution reviewed mNC-FET involving single euploid blastocysts from 2016 to 2020. Comparison groups were divided by pre-pregnancy BMI (kg/m) category: normal weight (18.

Purpose: To investigate the pregnancy and neonatal outcomes of letrozole-stimulated frozen embryo transfer (LTZ-FET) cycles compared with natural FET cycles (NC-FET).

Methods: Our retrospective cohort included all LTZ-FET (n = 161) and NC-FET (n = 575) cycles that transferred a single euploid autologous blastocyst from 2016 to 2020 at Stanford Fertility Center. The LTZ-FET protocol entailed 5 mg of daily letrozole for 5 days starting on cycle day 2 or 3.

This case report describes the evaluation and management of a 32-year-old woman who presented shortly after a fetal demise at 23 weeks of gestation with multiple symptoms, including bloody vaginal discharge. Although the initial diagnostic concern was for metastatic malignancy, the patient was ultimately determined to have disseminated tuberculosis. Genital tuberculosis is common worldwide, yet guidelines for evaluation are limited.

Objective: The aim of this study was to quantify the likelihood of assessing all mandated fetal views during the second-trimester anatomy ultrasound prior to the proposed federal 20-week abortion ban.

Study Design: Retrospective cohort study of a random sample of 1,983 patients undergoing anatomy ultrasound in 2017 at a tertiary referral center. The difference in proportion of incomplete anatomic surveys prior compared with after 20-week gestation was analyzed using and adjusted logistic regression; difference in mean days elapsed from anomaly diagnosis to termination tested using -tests and survival analysis.

In the midst of the SARS-CoV-2 pandemic, the US Association of American Medical Colleges (AAMC) required residency programme transition from in-person to virtual interviews for all applicants. The new virtual format upended a system that has relied on programmes and applicants balancing the likelihood of acceptance with the financial and time demands of cross-country travel.In this commentary, we address the history of residency interviewing in the USA and the emerging changes that are taking place in light of virtual interviews.

Purpose Of Review: To describe barriers to provision of postpartum permanent contraception at patient, hospital, and insurance levels.

Recent Findings: Permanent contraception remains the most commonly used form of contraception in the United States with the majority of procedures performed during birth-hospitalization. Many people live in regions with a high Catholic hospital market share where individual contraceptive plans may be refused based on religious doctrine.

Objective: Permanent contraception has historically been more prevalent among non-White women with lower education and income. Given increasing popularity of long-acting reversible contraception (LARC), we examine changing sociodemographic patterns of permanent contraception and LARC.

Study Design: We performed a descriptive analysis of the National Survey of Family Growth (NSFG) from 2006 to 2017, with multivariable analyses of the 2006 to 2010 and 2015 to 2017 cohorts.

Recent outbreaks of Ebola virus disease (2013-2016) and Zika virus (2015-2016) bring renewed recognition of the need to understand social pathways of disease transmission and barriers to care. Social scientists, anthropologists in particular, have been recognised as important players in disease outbreak response because of their ability to assess social, economic and political factors in local contexts. However, in emergency public health response, as with any interdisciplinary setting, different professions may disagree over methods, ethics and the nature of evidence itself.

Type 1 diabetes (T1D) results from immune-mediated destruction of insulin-producing β-cells. The killing of β-cells is not currently measurable; β-cell functional studies routinely used are affected by environmental factors such as glucose and cannot distinguish death from dysfunction. Moreover, it is not known whether immune therapies affect killing.
