Effect of soy isoflavones on measures of estrogenicity: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Despite recommendations to increase plant food consumption for public and planetary health and the role that soy foods can play in plant-predominant diets, controversies around the effects of soy foods and especially soy isoflavones, are a barrier to their intake. Given their cardioprotective effects and ability to alleviate menopausal symptoms, addressing these concerns is particularly relevant to women. OBJECTIVE: This systematic review and meta-analysis of randomized controlled trials aimed to determine the effect of soy isoflavones on measures of estrogenicity in postmenopausal women. METHODS: MEDLINE, Embase, and Cochrane Library were searched through August 2024 for randomized trials 3-months investigating soy isoflavones versus non-isoflavone controls in postmenopausal women. Outcomes included endometrial thickness (ET), vaginal maturation index (VMI), follicle-stimulating hormone (FSH), and estradiol. Independent authors extracted data and assessed risk of bias. GRADE (grading of recommendations assessment, development, and evaluation) was used to assess certainty of evidence. RESULTS: We included 40 trials (52 trial comparisons, n=3285) assessing the effect of a median reported dose of 75mg/day of soy isoflavones in substitution for non-isoflavone controls over a median of 24 weeks. Soy isoflavones had no statistically significant effect on any measure of estrogenicity; ET (mean difference, -0.22mm [95% confidence interval, -0.45, 0.01mm], PMD=0.059), VMI (2.31 [-2.14, 6.75], PMD=0.310), FSH (-0.02IU/L [-2.39, 2.35IU/L], PMD=0.987), and estradiol (1.61pmol/L [-1.17, 4.38pmol/L], PMD=0.256). The certainty of evidence was high-to-moderate for all outcomes. CONCLUSIONS: Current evidence suggests that soy isoflavones do not exhibit estrogenic effects compared to non-isoflavone controls on 4 measures of estrogenicity in postmenopausal women. This synthesis supports that soy isoflavones likely act as selective estrogen receptor modulators, differing clinically from the hormone estrogen. Addressing public health concerns may promote soy foods as high-quality plant protein sources with low environmental impact and cost, particularly benefiting postmenopausal women, and aligning with sustainable dietary patterns and guidelines.

Are we ready for human papillomavirus testing? Assessment of patient knowledge of and preferences for cervical cancer screening in Ontario.

OBJECTIVE: To determine patient knowledge and preferences about primary human papillomavirus (HPV) testing. DESIGN: Cross-sectional survey. SETTING: Two family practice clinics (urban and suburban) and the social media platforms of 2 hospitals in the greater Toronto area between January and February 2023. PARTICIPANTS: A total of 413 Ontario residents aged 25 to 69 years, with a cervix, who qualified for Papanicolaou (Pap) screening and could communicate in English. METHODS: Electronic survey containing questions about knowledge of, and preferences for, cervical cancer screening, including types of screening and screening intervals, and about education related to HPV and screening intervals. MAIN FINDINGS: Of 441 potential participants, 426 were eligible and consented to participate in the study; ultimately 413 provided completed or partially completed surveys (96.9% response rate). Of those who completed a recent Pap test, 57.8% (208 of 360) knew of HPV testing. Initially, 27.8% thought HPV testing was better than Pap testing for cervical cancer screening. After learning HPV tests exist and have self-sampling options, most participants preferred HPV testing (self-sampling 46.3%, provider sampling 34.1%). Annual cervical cancer screening was preferred by 50.1% of participants despite knowing that, for most people, Pap tests should be conducted every 3 years (74.8%). After learning about HPV testing, participants were more likely to prefer 5-year screening intervals (43.8%); however, those in the family practice group were still more likely to prefer 3-year intervals compared with those in the social media group (P<.01). CONCLUSION: Participants in this study identified a preference for HPV testing and self-sampling options. Concerns were raised about extended screening intervals and the safety of self-collected samples that need to be addressed in public health education initiatives during rollout of new screening programs.

Building Healthy Babies: A Mixed-Methods Needs Assessment for a Pre-Conception Program in Ontario.

OBJECTIVES: The objective of this study was to gather Ontario clinicians' and public members' views on the design of a pre-conception patient education program. METHODS: In this mixed-methods study, online surveys comprised of rank order, multiple choice, and short answer questions were completed by clinicians and public members. Semi-structured focus groups consisting of 2-6 participants each were then held via videoconference. Demographic variables and survey responses were analyzed quantitatively using descriptive and summary statistics. Descriptive thematic qualitative analysis using the constant comparative method of grounded theory was completed on each transcript to generate themes. RESULTS: A total of 168 public members and 43 clinicians in Ontario completed surveys, while 11 clinicians and 11 public members participated in the focus groups. A pre-conception program in Ontario was felt to be important. An individual appointment with a primary care provider was the favoured program format per survey responses, whereas a virtual format with an interactive component was preferred among focus group participants. Important topics to include were pre-conception health (infertility, genetic screening, folic acid), prenatal and postpartum counselling (diet, activity, substance use, prenatal care, postpartum course), and medical optimization in pregnancy (high-risk medical conditions, medications, mental health). Both groups emphasized the need to consider accommodations for marginalized populations and various cultures and languages. CONCLUSION: A standardized pre-conception patient education program is felt to be of high value by Ontario clinicians and public members. A pre-conception program may help improve obstetrical outcomes and decrease rates of major congenital anomalies in Ontario.

A Comparison of Lichen Sclerosus and Vulvodynia Content Across Social Media Platforms: What Is Trending Over Time.

OBJECTIVES: Vulvovaginal diseases are common gynecologic complaints and patients often turn to social media (SM) for medical information. The objective of this study is to examine vulvovaginal content on SM and how it has changed over time. MATERIALS AND METHODS: Four SM platforms were searched (i.e., Facebook, Instagram, Twitter, and YouTube) at 2 time points from March 30 to May 7, 2021, and again from November 24 to December 10, 2022. Newer SM platforms became popular during this time interval and thus TikTok and Reddit were included in the search in 2022. This study focused on 2 common vulvovaginal conditions: lichen sclerosus and vulvodynia. The SM platforms were searched for content on these conditions and the type of content, language, and country of origin were assessed. RESULTS: A total of 1228 SM accounts, posts, and pages were assessed. Lichen sclerosus content on SM was mostly informational (32.6%), whereas vulvodynia content was mostly personal experience (30.5%). Patient support groups were significantly more popular in 2021 compared with 2022 and professional groups were more common in 2022 compared with 2021 ( p < .001). Overall, Facebook and Instagram consisted mostly of patient support groups, YouTube had both informational and professional videos, TikTok had mostly personal experiences and healthcare professional videos, and Reddit was mostly discussions about patient personal experiences. CONCLUSIONS: The current study highlights the content and quantifies user engagement of lichen sclerosus and vulvodynia on SM.

The International Society for the Study of Vulvovaginal Disease (ISSVD) Vulvar Awareness Day Campaign: Knowledge of Vulvovaginal Diseases Among Italian Obstetrics and Gynecology Residents.

OBJECTIVES: The objective of this study is to investigate vulvovaginal disease (VVD) awareness in Italian obstetrics and gynecology (Ob/Gyn) residents. MATERIALS AND METHODS: A 25-question survey on VVD basic knowledge (17 questions) and willingness to improve it (8 questions) was distributed through Ob/Gyn resident online group chats, from different Italian Universities in January 2023. A total number of 250 residents were invited to participate; 124 responses were obtained (response rate: 50%). Data were collected and analyzed using descriptive statistics through REDCap. RESULTS: Overall, 87 of the 124 respondents (70%) fully completed the questionnaire and represented the study group. Residents were distributed among years of residency: 15% first year, 31% second year, 23% third year, 11% fourth year, and 20% fifth year. Most (60%) never attended a VVD clinic during residency, with an increasing percentage of attendance in later residency years (15% at first year vs 65% at fifth).Participants reported low knowledge of vulvar precancerous lesions and vulvoscopy but better knowledge of vaginitis, vulvar self-examination, and lichen sclerosus. Of the respondents, 50% were not satisfied with the education provided during residency, and more than 60% lacked confidence in managing VVD.All participants expressed a strong desire to improve their knowledge and skills, with 100% agreeing that every gynecologist should know the "basics" and 98% wanting to improve their knowledge through webinars (45%), lessons (34%), newsletters, and videos (19%). CONCLUSION: Our findings indicate a significant need to improve VVD knowledge among Italian Ob/Gyn residents. Further efforts are necessary to provide information about VVD and comprehensive training programs in Italian Universities.

"Check Your Vulva"-A Patient Education and Virtual Vulva Care Pilot Project.

OBJECTIVE: The aim of the study is to identify whether vulvar self-examination learned from a web site could lead to a self-identification of vulvar lesions and the feasibility of virtual vulvar care with patient submitted photos. MATERIALS AND METHODS: The study used a prospective cohort design in a tertiary academic hospital over a 1-year period. Eligible participants who self-identified a vulvar lesion/skin changes were invited to send vulvar photos through a secure patient portal and schedule a phone consult to discuss diagnosis/management. Clinical data, photo interpretability, and patient satisfaction measures were collected. Self-referral patients versus vulva clinic waitlist patients were analyzed separately. RESULTS: Few people were interested in submitting vulvar photos online. Twenty-eight participants directly contacted the study, 8 consented, and 6 sent in vulvar photos. Forty four of 476 on the waitlist consented but only 24 of 44 sent in photos (5% of waitlist patients). The median time for a virtual assessment was 7 days for study participants while it was 18 months for the in-person usual care pathway. Most patient submitted photos were assessable. However, 60% participants needed help from another person to take the photos. More than 90% of patients required an in-person visit for their vulvar condition/concerns. While most patients were happy with the virtual process, 58% rated their satisfaction with the ease of taking photos of the genital region as "fair" or "poor." CONCLUSIONS: Virtual care with photos/phone calls might be feasible, although most patients are unlikely to participate. Because of patient discomfort, unease with taking photos, and patient privacy concerns, vulvar care should continue to be in-person for most new consults.

2023 Canadian Colposcopy Guideline: A Risk-Based Approach to Management and Surveillance of Cervical Dysplasia.

This guideline provides evidence-based guidance on the risk-based management of cervical dysplasia in the colposcopy setting in the context of primary HPV-based screening and HPV testing in colposcopy. Colposcopy management of special populations is also discussed. The guideline was developed by a working group in collaboration with the Gynecologic Oncology Society of Canada (GOC), Society of Colposcopists of Canada (SCC) and the Canadian Partnership Against Cancer (CPAC). The literature informing these guidelines was obtained through a systematic review of the relevant literature via a multi-step search process led by information specialists. The literature was reviewed up to June 2021 with manual searches of relevant national guidelines and more recent publications. Quality of the evidence and strength of recommendations was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. The intended users of this guideline include gynecologists, colposcopists, screening programs and healthcare facilities. Implementation of the recommendations is intended to promote equitable and standardized care for all people undergoing colposcopy in Canada. The risk-based approach aims to improve personalized care and reduce over-/under-treatment in colposcopy.

Steroid Phobia in Patients With Vulvar Lichen Sclerosus.

OBJECTIVE: Steroid phobia in people with dermatologic conditions is associated with noncompliance with topical corticosteroids (TCS). Although it has not been studied in those with vulvar lichen sclerosus (vLS), first-line therapy is lifelong maintenance TCS, and noncompliance is associated with impaired quality of life, progression of architecture changes, and vulvar skin cancer. The authors aimed to measure steroid phobia in patients with vLS and determine their most valued sources of information to direct future interventions to address this phenomenon. METHODS: The authors adapted a preexisting, validated scale for steroid phobia (TOPICOP), which is a 12-item questionnaire that produces a score of 0 = no phobia and 100 = maximum phobia. The anonymous survey was distributed across social media platforms with an in-person component at the authors' institution. Eligible participants included those with clinical or biopsy-proven LS. Participants were excluded if they did not consent or did not communicate in English. RESULTS: The authors obtained 865 online responses over a 1-week period. The in-person pilot obtained 31 responses, with a response rate of 79.5%. Mean global steroid phobia score was 43.02 (21.9)% and in-person responses were not significantly different (40.94 [16.03]%, p = .59). Approximately 40% endorsed waiting as long as they can before using TCS and stop as soon as possible. The most influential sources to improve patient comfort with TCS were physician and pharmacist reassurance over online resources. CONCLUSIONS: Steroid phobia is common in patients with vLS. Focused efforts to address steroid phobia among health care providers is the next best step toward improving patient comfort with TCS.

Genital and extragenital oncological risk in women with vulvar lichen sclerosus: A multi-center Italian study.

Vulvar lichen sclerosus is a chronic inflammatory disease involving vulvar skin. The risk of developing invasive vulvar cancer for women with LS is reported in the literature, but the risk of extra-vulvar tumors has been under-investigated. This multicentric study aims to estimate the risk of developing cancers in a cohort of women with a diagnosis of vulvar lichen sclerosus. METHODS: A cohort of women diagnosed with and treated for vulvar lichen sclerosus in three Italian gynecological and dermatological clinics (Turin, Florence, and Ferrara) was retrospectively reviewed. Patient data were linked to cancer registries of the respective regions. The risk of subsequent cancer was estimated by dividing the number of observed and expected cases by the standardized incidence ratio. RESULTS: Among 3414 women with a diagnosis of vulvar lichen sclerosus corresponding to 38,210 person-years of follow-up (mean 11.2 years) we identified 229 cancers (excluding skin cancers and tumors present at the time of diagnosis). We found an increased risk of vulvar cancer (standardized incidence ratio = 17.4; 95 % CL 13.4-22.7), vaginal cancer (standardized incidence ratio = 2.7; 95 % CL 0.32-9.771), and oropharyngeal cancer (standardized incidence ratio = 2.5; 95 % CL 1.1-5.0), and a reduced risk of other gynecological tumors (cervical, endometrial, ovarian) and breast cancer. CONCLUSIONS: Patients with vulvar lichen sclerosus should undergo annual gynecological check-up with careful evaluation of the vulva and vagina. The increased risk of oropharyngeal cancer also suggests the need to investigate oropharyngeal cavity symptoms and lesions in patients with vulvar lichen sclerosus.

Core outcome domains for lichen sclerosus: a CORALS initiative consensus statement.

BACKGROUND: Lichen sclerosus (LS) is a chronic inflammatory condition mainly affecting genital skin. It causes distressing symptoms that impact daily quality of life (QoL). It causes progressive anatomical changes and a potential risk of cancer. Published randomized controlled trials are of varying methodological quality and difficult to combine in meta-analyses. This is partly due to lack of agreed outcome measures to assess treatment response. Identification of core outcome sets (COSs), which standardize key outcomes to be measured in all future trials, is a solution to this problem. OBJECTIVES: To obtain international agreement on which outcome domains should be measured in interventional trials of genital LS. METHODS: Recommended best practice for COS domain development was followed: (i) identification of potential outcome domains: a long list was generated through an up-to-date LS literature search, including information collected during the LS priority-setting partnership; (ii) provisional agreement of outcome domains: a three-stage multi-stakeholder international electronic-Delphi (e-Delphi) consensus study; (iii) final agreement of outcome domains: online consensus meeting with international stakeholders including anonymized voting. RESULTS: In total, 123 participants (77 patients, 44 health professionals, 2 researchers) from 20 countries completed three rounds of the e-Delphi study. Eleven outcome domains were rated as 'critical' and were discussed at the online consensus meetings. The first set of consensus meetings involved 42 participants from 12 countries. Consensus was met for 'symptoms' (100% agreed) and 'QoL - LS-specific' (92% agreed). After the second set of meetings, involving 29 participants from 12 countries, 'clinical (visible) signs' also met consensus (97% agreed). CONCLUSIONS: The international community has agreed on three key outcome domains to measure in all future LS clinical trials. We recommend that trialists and systematic reviewers incorporate these domains into study protocols with immediate effect. CORALS will now work with stakeholders to select an outcome measurement instrument per prioritized core domain.

The Quality and Quantity of Lower Genital Tract Research Across Multiple Journals.

OBJECTIVE: This study aimed to determine the quantity and quality of lower genital tract disease (LGTD) research by topic published across a variety of gynecology and dermatology journals. METHODS: Authors accessed all articles that were rejected (1,111, 59.5%) and accepted (755, 40.5%) by the Journal of Lower Genital Tract Disease ( JLGTD ) from 2008 to 2020. Studies were categorized by key topic: Cervix, Human Papillomavirus, Vulva, Vagina, Anal, and Other. Studies were further subcategorized based on methodology. These data were compared with all LGTD publications from 2018 to 2020 in 4 other widely recognized journals ( Obstetrics and Gynecology , The British Journal of Obstetrics and Gynaecology , JAMA Dermatology , and the British Journal of Dermatology ). RESULTS: Most JLGTD -accepted submissions were related to the cervix (298/755, 39.5%) and vulva (189/755, 25.0%). Rates of acceptance were similar across all key topic areas. Only 3.2% of publications in the other 4 journals (92/2,932) were related to LGTD topics. Across all 5 journals, vulva studies were most commonly case reports/case series (82/218, 37.6%), with a low prevalence of systematic reviews/meta-analyses (4/218 1.8%). In comparison, cervix studies had the highest number of systematic reviews/meta-analyses (14/317, 4.4%) and the lowest number of case reports (14/317, 4.4%). CONCLUSIONS: Vulvar research is of lower quality compared with cervix research published across 5 journals. Comparing accepted versus rejected articles in JLGTD , there is no publication bias against vulva topics noted; rather, the overall research quality in vulva is lower than that of cervical disease. This is a call to action for higher quality vulvar research.

Adapting obstetric and neonatal services during the COVID-19 pandemic: a scoping review.

BACKGROUND: The provision of care to pregnant persons and neonates must continue through pandemics. To maintain quality of care, while minimizing physical contact during the Severe Acute Respiratory Syndrome-related Coronavirus-2 (SARS-CoV2) pandemic, hospitals and international organizations issued recommendations on maternity and neonatal care delivery and restructuring of clinical and academic services. Early in the pandemic, recommendations relied on expert opinion, and offered a one-size-fits-all set of guidelines. Our aim was to examine these recommendations and provide the rationale and context to guide clinicians, administrators, educators, and researchers, on how to adapt maternity and neonatal services during the pandemic, regardless of jurisdiction. METHOD: Our initial database search used Medical subject headings and free-text search terms related to coronavirus infections, pregnancy and neonatology, and summarized relevant recommendations from international society guidelines. Subsequent targeted searches to December 30, 2020, included relevant publications in general medical and obstetric journals, and updated society recommendations. RESULTS: We identified 846 titles and abstracts, of which 105 English-language publications fulfilled eligibility criteria and were included in our study. A multidisciplinary team representing clinicians from various disciplines, academics, administrators and training program directors critically appraised the literature to collate recommendations by multiple jurisdictions, including a quaternary care Canadian hospital, to provide context and rationale for viable options. INTERPRETATION: There are different schools of thought regarding effective practices in obstetric and neonatal services. Our critical review presents the rationale to effectively modify services, based on the phase of the pandemic, the prevalence of infection in the population, and resource availability.

Learning on the Go: Assessing Knowledge Gained From Medical Podcasts Created for Vulvovaginal Disease Education.

OBJECTIVE: The aim of the study was to evaluate the effectiveness of "The Vulva Diaries" podcast as a novel learning tool for vulvovaginal disease education. MATERIALS AND METHODS: Medical students and residents were invited to participate in the study using social media advertisements. Online pretests and posttests, one based on a podcast episode regarding genital herpes and the other on lichen sclerosus, were used to assess changes in knowledge level pre- and post-podcast listening in medical students and residents respectively. A second posttest was sent out 2 weeks after the first to assess knowledge retention. Results were analyzed using paired t tests comparing mean scores before and after podcast. RESULTS: In medical students, the average test score increased by 20% (n = 56, p < .001). Similarly, in residents the average test score increased by 23.1% (n = 22, p < .001). Medical students and residents rated their average preference for using podcasts as compared with other resources at 3.6 and 3.7/5, respectively. Furthermore, in both groups, there was no significant difference between average scores for posttest 1 versus posttest 2 written 2 weeks later suggested excellent knowledge retention. CONCLUSIONS: "The Vulva Diaries" podcast increases knowledge on vulvovaginal disease and is an effective learning tool for health care trainees in women's health. This study emphasizes the role of podcasts as a valuable educational resource within gynecology. The success of such initiatives will hopefully bolster the effort to correct the lack of provider knowledge in treating vulvovaginal diseases.
