RESUMEN

The field of reproductive endocrinology and infertility (REI) is at a crossroads; there is a mismatch between demand for reproductive endocrinology, infertility and assisted reproductive technology (ART) services, and availability of care. This document's focus is to provide data justifying the critical need for increased provision of fertility services in the United States now and into the future, offer approaches to rectify the developing physician shortage problem, and suggest a framework for the discussion on how to meet that increase in demand. The Society of REI recommend the following: 1. Our field should aggressively explore and implement courses of action to increase the number of qualified, highly trained REI physicians trained annually. We recommend efforts to increase the number of REI fellowships and the size complement of existing fellowships be prioritized where possible. These courses of action include: a. Increase the number of REI fellowship training programs. b. Increase the number of fellows trained at current REI fellowship programs. c. The pros and cons of a 2-year focused clinical fellowship track for fellows interested primarily in ART practice were extensively explored. We do not recommend shortening the REI fellowship to 2 years at this time, because efforts should be focused on increasing the number of fellowship training slots (1a and b). 2. It is recommended that the field aggressively implements courses of action to increase the number of and appropriate usage of non-REI providers to increase clinical efficiency under appropriate board-certified REI physician supervision. 3. Automating processes through technologic improvements can free providers at all levels to practice at the top of their license.

RESUMEN

Purpose: To understand women's perspectives, attitudes, and beliefs surrounding menopause transition and increase understanding of digital technology use for symptom management. Patients and Methods: Information was obtained using three studies of women aged 40-65 years experiencing menopause transition symptoms. The HealthyWomen online cross-sectional survey was designed to reflect an inclusive sociodemographic sample representative of the US population. BECOME was a blinded, ethnographic, qualitative research study of women's menopause transition experiences and comprised facilitator-led online asynchronous discussions, online homework entries, and audio-only teleconferences. The NODE.Health online, two-part, cross-sectional patient survey was designed to capture patient and healthcare provider (HCP) sentiment about the use of digital health technologies to address gaps in perimenopausal symptom knowledge and management. Results: The HealthyWomen survey included 1045 participants, 37 were included in BECOME, and 100 completed the NODE.Health survey. Hot flashes, night sweats, and sleep problems were the most frequently experienced symptoms in the HealthyWomen survey, and over half of participants experiencing symptoms felt the need to seek relief. Whether menopause was considered a medical problem or natural process differed by self-identified race, culture, and ethnicity, as did the likelihood of consulting a HCP over symptoms. Participants preferred to discuss menopause transition with HCPs who did not rush them, were good listeners, and had expertise in the area. Most technology experience was with health websites, but nearly half were unsatisfied with online resources describing menopause-related symptoms. Convenience, ease of use, and accessibility were the most common reasons for pursuing digital health technology. Conclusion: Factors such as cultural beliefs, values and attitudes towards menopause determine personal experiences. More open discussions with friends, family, and HCPs may raise awareness and reduce barriers to seeking help. To provide optimal care throughout the menopause transition, HCPs should consider patients' psychosocial and cultural backgrounds, and personal and subjective perspectives.

RESUMEN

IMPORTANCE AND OBJECTIVE: Little is known and reported about the experiences of African American women as they transition to and experience menopause. Accepted norms are based on the experience of a predominantly White population. The aim of this study is to review available data about the distinct experiences of African American women during the menopause transition and menopause. METHODS: A literature search was developed and executed by the review team in collaboration with a health sciences librarian. The search combined controlled vocabulary and title/abstract terms related to the health status disparities of African Americans in the menopause transition and menopause. The following databases were searched from inception through April 28, 2022: PubMed, Scopus (Elsevier), and Web of Science Core Collection (Clarivate). DISCUSSION AND CONCLUSION: African American women experience distinct differences in physical, psychological, social, and quality of life measures during menopause. Increasing awareness about the unique menopause experiences of African American women is critically important to improve the health of this underserved population.

RESUMEN

A cross-sectional survey design was used to assess Arkansas parents'/guardians' intentions to vaccinate their child against COVID-19. Parents/guardians whose oldest child was age 0-11 years (n = 171) or 12-17 years (n = 198) were recruited between 12 July and 30 July 2021 through random digit dialing. Among parents/guardians with an age-eligible child, age 12-17, 19% reported their child had been vaccinated, and 34% reported they would have their child vaccinated right away. Among parents/guardians with a child aged 0-11, 33% of parents/guardians reported they would have their child vaccinated right away. Twenty-eight percent (28%) of parents/guardians whose oldest child was 12-17 and 26% of parents/guardians whose oldest child was 0-11 reported they would only have their child vaccinated if their school required it; otherwise, they would definitely not vaccinate them. For both groups, parents'/guardians' education, COVID-19 vaccination status, and COVID-19 vaccine hesitancy were significantly associated with intentions to vaccinate their child. More than a third of parents/guardians whose child was eligible for vaccination at the time of the survey reported they intended to have them vaccinated right away; however, they had not vaccinated their child more than two months after approval. This finding raises questions about the remaining barriers constraining some parents/guardians from vaccinating their child.

RESUMEN

ABSTRACT: Charting the Path to Health in Midlife and Beyond: The Biology and Practice of Wellness was a Translational Science Symposium held on Tuesday, September 21, 2021. Foundational psychosocial and behavioral approaches to promote healthy aging and strategies to disseminate this information were discussed. The following synopsis documents the conversation, describes the state of the science, and outlines a path forward for clinical practice. Wellness, in its broadest sense, prioritizes an orientation toward health, and an embrace of behaviors that will promote it. It involves a journey to improve and maintain physical and mental health and overall well-being to fully engage and live one's best life. It is more about recognizing and optimizing what one can do than what one cannot do and emphasizes the individual's agency over changing what they are able to change. Wellness is therefore not a passive state but rather an active goal to be sought continually. When viewed in this fashion, wellness is accessible to all. The conference addressed multiple aspects of wellness and embraced this philosophy throughout.

RESUMEN

Background: Minority and low socioeconomic communities may face practical barriers to vaccination, including decreased access to health care and less trust in healthcare organizations; however, few studies have focused on these barriers as the cause of differential vaccine uptake. We worked with community partners to implement and evaluate two community-driven approaches to COVID-19 vaccination distribution-through faith-based organizations (FBOs) and outpatient clinics-with a focus on understanding the differences between the populations who accessed each distribution method. Methodology: Participants who came to the vaccination locations were approached and asked to complete a survey during their 15 min post-vaccination observation period. Differences between distribution locations were examined using Chi-square tests. Results: The survey rendered 1,476 valid responses, with a total of 927 participants recruited at clinical locations and 519 at FBOs during vaccination events. There were significant differences by race/ethnicity, with distribution methods at FBOs reaching a higher proportion of Hispanic/Latino and Marshallese participants. The proportion of uninsured participants who had lower health literacy and had lower educational attainment was higher with the FBO distribution method. FBO participants were more likely to report "completely" trusting the COVID-19 vaccine. There was no significant difference between FBO and clinic participants with regard to the level of vaccine hesitancy. There were no statistically significant differences with regard to access. Conclusion: A higher proportion of Hispanic/Latino and Marshallese participants utilized FBOs for vaccination, suggesting collaborations with FBOs can potentially increase vaccination uptake among minority communities and help mitigate vaccination disparities.

RESUMEN

The demographics of the United States are rapidly changing, and our health care workforce is not keeping pace with the population trends. The American Society for Reproductive Medicine (formerly The American Fertility Society) recognizes the need to increase diversity and is committed to promoting diversity across our membership and leadership as well as promoting equitable quality reproductive care to all patients. In the fall of 2020, the American Society for Reproductive Medicine convened a Diversity, Equity, and Inclusion Task Force to evaluate and make recommendations on the basis of findings to increase diversity to achieve equity and inclusion of reproductive and infertility services for all women. This article focuses on specific barriers that Black or African American patients face in accessing quality care and that provider's face in training and inclusion in reproductive medicine. Multiple publications have confirmed an improvement in health outcome when there is congruence between the patient and the provider. There is a stark contrast between the racial and ethnic diversity of our providers and other support personnel compared with that of our patients. Despite our best intent to minimize the effects of implicit and explicit bias, mistrust and misunderstandings when there is discordance between patients and providers negatively impacts care. To increase provider diversity, it is crucial that we prioritize pipeline programs that recruit and support underrepresented minority in medicine physicians. Specific recommendations are made to increase diversity in the pipeline to improve patient access to culturally competent quality reproductive medicine care with optimal outcomes.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the effect of epigallocatechin gallate (EGCG) on rat leiomyoma (ELT3) cells in vitro and in a nude mice model. STUDY DESIGN: ELT3 cells were treated with various concentrations of EGCG. Cell proliferation, proliferation cell nuclear antigen (PCNA), and cyclin-dependent kinase 4 (Cdk4) protein levels were evaluated. ELT3 cells were inoculated subcutaneously in female athymic nude mice. Animals were fed 1.25 mg EGCG (in drinking water)/mouse/day. Tumors were collected and evaluated at 4 and 8 weeks after the treatment. RESULTS: Inhibitory effect of EGCG (200 micromol/L) on ELT3 cells was observed after 24 hours of treatment (P < .05). At > or = 50 micromol/L, EGCG significantly decreased PCNA and Cdk4 protein levels (P < .05). In vivo, EGCG treatment dramatically reduced the volume and weight of tumors at 4 and 8 weeks after the treatment (P < .05). The PCNA and Cdk4 protein levels were significantly reduced in the EGCG-treated group (P < .05). CONCLUSION: EGCG effectively inhibits proliferation and induces apoptosis in rat ELT3 uterine leiomyoma cells in vitro and in vivo.

RESUMEN

BACKGROUND: Hormone replacement therapy (HT) for post-menopausal women is associated with increased incidence of ischemic stroke risk. Effects of HT on stroke related deficits and functional outcomes in acute ischemic stroke (AIS) are uncertain. We retrospectively examined female consult data for HT use and National Institutes of Health Stroke Score (NIHSS) at baseline and recovery for 2015 and 2016 in a large stroke telemedicine program. HYPOTHESIS: The age of women who acknowledged HT use will negatively impact stroke severity and outcomes. METHODS: We analyzed consult data from two consecutive years for all women and included HT use, current age, and baseline and 24 h NIHSS's. We included all women consults regardless of IV Alteplase treatment. 24 h NIHSS and three month modified Rankin scale (mRS) were included from women given IV Alteplase. RESULTS: Strokes were identified in 523 women and 244 women received Alteplase therapy. Women without HT use numbered 459 and 64 women listed HT use. Mean NIHSS scores regardless of HT use significantly improved 24 h NIHSS vs. baseline NIHSS (p<0.0001). Baseline NIHSS scores were significantly improved in women on HT vs. non-HT users (p=0.01) in women age 50 to 79 years. Although mean NIHSS scores at 24h was not different from HT to no HT use (4.9 ± 1.6 vs. 7.8 ± 0.6, p=0.08) a trend was present for lower NIHSS scores for women 50-79 years. The mRS scores at three months indicated significant improvements among HT users vs. non-HT use (1.46 ± 0.4 vs. 2.51 ± 0.2, p=0.05). CONCLUSION: While cautions persist on the use, route and dosage of HT for risks of ischemic stroke, the HT moderation of AIS deficits and outcomes in women <80 years of age warrants further investigation.

RESUMEN

OBJECTIVE: Increased mammographic breast density is a well-established risk factor for breast cancer development, regardless of age or ethnic background. The current gold standard for categorizing breast density consists of a radiologist estimation of percent density according to the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) criteria. This study compares paired qualitative interpretations of breast density on digital mammograms with quantitative measurement of density using Hologic's Food and Drug Administration-approved R2 Quantra volumetric breast density assessment tool. Our goal was to find the best cutoff value of Quantra-calculated breast density for stratifying patients accurately into high-risk and low-risk breast density categories. METHODS: Screening digital mammograms from 385 subjects, aged 18 to 64 years, were evaluated. These mammograms were interpreted by a radiologist using the ACR's BI-RADS density method, and had quantitative density measured using the R2 Quantra breast density assessment tool. The appropriate cutoff for breast density-based risk stratification using Quantra software was calculated using manually determined BI-RADS scores as a gold standard, in which scores of D3/D4 denoted high-risk densities and D1/D2 denoted low-risk densities. RESULTS: The best cutoff value for risk stratification using Quantra-calculated breast density was found to be 14.0%, yielding a sensitivity of 65%, specificity of 77%, and positive and negative predictive values of 75% and 69%, respectively. Under bootstrap analysis, the best cutoff value had a mean ± SD of 13.70% ± 0.89%. CONCLUSIONS: Our study is the first to publish on a North American population that assesses the accuracy of the R2 Quantra system at breast density stratification. Quantitative breast density measures will improve accuracy and reliability of density determination, assisting future researchers to accurately calculate breast cancer risks associated with density increase.

RESUMEN

BACKGROUND: Women with symptomatic uterine leiomyomas (fibroids) may have iron-deficiency anemia (IDA); therefore, surgery places them at risk of blood-borne morbidity from perioperative transfusions. Such women might benefit from a preoperative treatment that restores hematologic normality and alleviates fibroid symptoms. OBJECTIVE: The purpose of this study was to examine the effects of a single preoperative depot injection of goserelin acetate plus iron treatment compared with iron monotherapy, in premenopausal women with IDA due to uterine leiomyomas. METHODS: This Phase III, randomized, multicenter, double-blind, controlled trial (12 weeks of treatment plus a 24-week follow-up period) was conducted from October 1997 to August 1999. Patients received an injection of goserelin acetate 10.8 mg (3-month formulation) or a sham, with both groups receiving PO iron (ferrous sulfate) 325-mg tablets TID during the 12-week treatment period. Surgery (hysterectomy or myomectomy) was planned for week 12. Hemoglobin (Hb) level, symptoms of uterine leiomyomas, requirement for blood transfusion throughout, ability to donate blood for autologous transfusion, and leiomyoma and uterine volume were assessed for efficacy. The tolerability assessment included bone mineral density measurements and subjective symptomatology (ie, menstrual bleeding [uterine hemorrhage], fatigue, pelvic pain, and pelvic pressure). RESULTS: A total of 110 women received treatment (n = 54, goserelin acetate 10.8 mg; n = 56, sham). The majority of patients (69.1%) were black and the mean age at study entry was 39.9 years, with a mean weight of 80.1 kg. At approximately 12 weeks, Hb levels were significantly higher in the goserelin group compared with the sham group (difference of least squares mean, 1.17 g/dL; 95% CI, 0.68-1.66; P < 0.001), and significantly more patients in the goserelin group had an increase in Hb concentration of >or=2 g/dL (odds ratio 6.36; 95% CI, 2.00-20.18; P < 0.001). A nonsignificant decrease in both uterine and leiomyoma volume was experienced by patients who administered goserelin compared with increases in the sham group. Uterine hemorrhage was also experienced numerically less often by goserelin-treated patients compared with those given the sham injection (9.3% vs 28.6%, respectively). One or more adverse events (AEs) were reported by 89% of patients in each treatment group. Goserelin acetate 10.8 mg was generally well tolerated by patients, with no serious drug-related AEs reported during this 36-week trial. CONCLUSION: A single, preoperative injection of goserelin acetate 10.8 mg in addition to PO iron 325 mg TID was associated with improved Hb levels in these premenopausal women with IDA due to uterine leiomyomas.

RESUMEN

Guidelines for screening of cervical cancer and pelvic exams for older women have recently changed. These changes may have unexpected sequelae in women over 65 years of age. This manuscript provides a review of gynecologic screening recommendations for older women in the U.S. and potential ramifications of these recent changes. Peer reviewed guidelines from the American College of Obstetrics and Gynecology, U.S. Preventative Task Force Services, the American Cancer Society, The Centers for Disease Control, and multiple original research articles and reviews were reviewed for this manuscript. Women over 65 are at greatest risk to develop late stage diagnoses of cancers, pelvic organ disease, incontinence, and infections. Clinicians will need to acutely consider this fact when communicating and screening this population. We conclude that practitioners should be aware of the new guidelines and should consider including gynecologic health history and symptom analysis as part of annual exams in women of all ages.

RESUMEN

More than 4 million menopausal women are from ethnic minority groups. Over the past 25 years, recognition of the importance of social, emotional, and physical changes of midlife to women's long-term health and well-being has emerged. Multiple factors influence how a woman perceives menopausal changes and what she addresses as associated symptoms. Factors such as educational level to socioeconomic status, health-related factors, stress, and marital status influence these choices. Increasingly, researchers are reporting on the impact of race and ethnicity on menopausal symptoms. Understanding similarities and differences among women's perceptions, attitudes, and expectations surrounding menopause improves delivery of culturally appropriate care and promotes lifestyles that may decrease symptoms and increase quality of life. Historically, the majority of the research in this area has been conducted in Western countries with clinical samples of women predominantly from European backgrounds. Thus, this population has shaped the emerging clinical picture of the midlife menopausal transition. Recently, studies of non-European women, both in the United States and internationally, indicate significant variations in their experiences during this transition, but these cultural differences have not broadened the understanding of the meaning of this universal experience. To date, there are still large knowledge gaps in race, ethnic, and cultural differences in menopausal health. The content of this review summarizes the current body of knowledge on racial differences in the menopause experience.

RESUMEN

Both basic science and clinical studies support the concept that vitamin D deficiency is involved in the pathogenesis of cardiovascular and renal diseases through its association with diabetes, obesity, and hypertension. Understanding the underlying mechanisms may provide a rationale for advocating adequate intake of vitamin D and calcium in all populations, thereby preventing many chronic diseases. This review explores the effect of vitamin D deficiency in the development of cardiovascular and renal diseases, and the role of vitamin D supplementation on cardiovascular outcomes. In addition, it highlights the importance of vitamin D intake for the prevention of adverse long-term health consequences, and in ways to facilitate the management of cardiovascular disease. This is particularly true for African American and postmenopausal women, who are at added risk for cardiovascular disease. We suggest that the negative cardiovascular effects of low vitamin D in postmenopausal women could be improved by a combined treatment of vitamin D and sex steroids acting through endothelium-dependent and/or -independent mechanisms, resulting in the generation of nitric oxide and calcitonin gene-related peptide (CGRP).

RESUMEN

OBJECTIVE: To systematically review the reporting of race/ethnicity in Society for Assisted Reproductive Technology (SART) Clinic Outcome Reporting System (CORS) publications. DESIGN: Systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology of literature published in PubMed on race/ethnicity that includes data from SART CORS. SETTING: Not applicable. PATIENT(S): Not applicable. INTERVENTION(S): In vitro fertilization cycles reported to SART. MAIN OUTCOME MEASURE(S): Any outcomes reported in SART CORS. RESULT(S): Seven publications were identified that assessed racial/ethnic disparities in IVF outcomes using SART data. All reported a racial/ethnic disparity. However, more than 35% of cycles were excluded from analysis because of missing race/ethnicity data. CONCLUSION(S): Review of current publications of SART data suggests significant racial/ethnic disparities in IVF outcomes. However, the potential for selection bias limits confidence in these findings, given that fewer than 65% of SART reported cycles include race/ethnicity. Our understanding of how race/ethnicity influences ART outcome could be greatly improved if information on race/ethnicity was available for all reported cycles.

RESUMEN

OBJECTIVE: To investigate the effects of epigallocatechin gallate (EGCG), an extract of green tea on cultured human leiomyoma cells (HuLM). DESIGN: Laboratory study. SETTING: University hospitals. PATIENT(S): Not applicable. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): The HuLM cells were treated with various EGCG concentrations. Cell proliferation was assayed using Hoechst 33258 dye, and apoptosis by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Total RNA was isolated, and gene expression profiling was performed on 84 key genes related to 18 different signal transduction pathways. The protein levels of PCNA, CDK4, BCL2, and BAX were examined by Western blot analysis. RESULT(S): The HuLM cells treated with EGCG showed a dose-dependent and time-dependent inhibition of cell proliferation. The TUNEL staining indicated a significant increase in apoptosis in HuLM cells treated with 100 µM of EGCG compared with untreated control. Gene expression profiling indicated that EGCG treatment up-regulated representative genes from the transforming growth factor ß (TGF-ß) and stress pathways, while inhibiting the survival pathway and NFκB-dependent inflammatory pathway. Western blot analysis confirmed that EGCG at ≥50 µM significantly decreased the expression of PCNA, CDK4, and BCL2 as well as increased the expression of the proapoptotic BAX in a dose-dependent manner. CONCLUSION(S): Epigallocatechin gallate inhibits the proliferation of HuLM cells and induces apoptosis. These results suggest that EGCG may be a potential anti-uterine fibroid agent acting through multiple signal transduction pathways.
