Prenatal delta-9-tetrahydrocannabinol exposure alters fetal neurodevelopment in rhesus macaques.

Prenatal cannabis use is associated with adverse offspring neurodevelopmental outcomes, however the underlying mechanisms are relatively unknown. We sought to determine the impact of chronic delta-9-tetrahydrocannabinol (THC) exposure on fetal neurodevelopment in a rhesus macaque model using advanced imaging combined with molecular and tissue studies. Animals were divided into two groups, control (n = 5) and THC-exposed (n = 5), which received a daily THC edible pre-conception and throughout pregnancy. Fetal T2-weighted MRI was performed at gestational days 85 (G85), G110, G135 and G155 to assess volumetric brain development. At G155, animals underwent cesarean delivery with collection of fetal cerebrospinal fluid (CSF) for microRNA (miRNA) studies and fetal tissue for histologic analysis. THC exposure was associated with significant age by sex interactions in brain growth, and differences in fetal brain histology suggestive of brain dysregulation. Two extracellular vesicle associated-miRNAs were identified in THC-exposed fetal CSF; pathway analysis suggests that these miRNAs are associated with dysregulated axonal guidance and netrin signaling. This data is indicative of subtle molecular changes consistent with the observed histological data, suggesting a potential role for fetal miRNA regulation by THC. Further studies are needed to determine whether these adverse findings correlate with long-term offspring neurodevelopmental health.

Timing of Coronavirus Disease 2019 (COVID-19) Vaccination and Effects on Menstrual Cycle Changes.

OBJECTIVE: To assess whether menstrual cycle timing (follicular or luteal phase) of coronavirus disease 2019 (COVID-19) vaccine administration is associated with cycle length changes. METHODS: We used prospectively collected (2021-2022) menstrual cycle tracking data from 19,497 reproductive-aged users of the application "Natural Cycles." We identified whether vaccine was delivered in the follicular or luteal phase and also included an unvaccinated control group. Our primary outcome was the adjusted within-individual change in cycle length (in days) from the average of the three menstrual cycles before the first vaccination cycle (individuals in the unvaccinated control group were assigned a notional vaccine date). We also assessed cycle length changes in the second vaccination cycle and whether a clinically significant change in cycle length (8 days or more) occurred in either cycle. RESULTS: Most individuals were younger than age 35 years (80.1%) and from North America (28.6%), continental Europe (33.5%), or the United Kingdom (31.7%). In the vaccinated group, the majority received an mRNA vaccine (63.8% of the full sample). Individuals vaccinated in the follicular phase experienced an average 1-day longer adjusted cycle length with a first or second dose of COVID-19 vaccine compared with their prevaccination average (first dose: 1.00 day [98.75% CI, 0.88-1.13], second dose: 1.11 days [98.75% CI, 0.93-1.29]); those vaccinated in the luteal phase and those in the unvaccinated control group experienced no change in cycle length (respectively, first dose: -0.09 days [98.75% CI, -0.26 to 0.07], second dose: 0.06 days [98.75% CI, -0.16 to 0.29], unvaccinated notional first dose: 0.08 days [98.75% CI, -0.10 to 0.27], second dose: 0.17 days [98.75% CI, -0.04 to 0.38]). Those vaccinated during the follicular phase were also more likely to experience a clinically significant change in cycle length (8 days or more; first dose: 6.8%) than those vaccinated in the luteal phase or unvaccinated (3.3% and 5.0%, respectively; P <.001). CONCLUSION: COVID-19 vaccine-related cycle length increases are associated with receipt of vaccination in the first half of the menstrual cycle (follicular phase).

A Social Media Survey of US Adolescent Preferences for Menstrual Bleeding Patterns.

STUDY OBJECTIVE: To assess preferences for menstrual pattern and acceptability and knowledge about the safety of induced amenorrhea among adolescents and young adults METHODS: We conducted a cross-sectional online survey of US residents aged 14-24 years at least 1 year post-menarche. Online recruitment was conducted via the social media platform TikTok on a teen reproductive health channel. Survey questions focused on menstrual history, menstrual pattern preferences, and demographic characteristics. The primary outcome was the proportion of postmenstrual individuals who would prefer amenorrhea vs scheduled bleeding. RESULTS: From 5113 potential respondents who accessed the eligibility screening, 3001 completed surveys and met the inclusion criteria. Most were aged 14-18 (63.7%), distributed proportionally among all US Census regions. When asked if they could pick their period-bleeding style without any permanent impacts, almost three-quarters chose no bleeding at all (amenorrhea; 71.5%) compared with scheduled periods (28.5%). However, 63.7% agreed or were uncertain when faced with the statement "It might be unsafe if hormone medications stop your period bleeding." After adjusting for age, gender expression, race, religion, heavy bleeding, and frequent bleeding, factors associated with preference for amenorrhea vs regular bleeding were younger age, masculine gender expression, White race, and non-Christian religious background. Baseline bleeding amount and frequency were not associated with preference for amenorrhea. CONCLUSION: More than two-thirds of US adolescents and young adults indicated a preference for medication-induced amenorrhea if the method was assured to not have any permanent effects on the body, despite highly prevalent misconceptions about health and safety.

Acceptability of human papillomavirus self-collection and the role of telehealth: a prospective, randomized study stratified by menopausal status.

OBJECTIVE: We investigated the utility of telehealth instruction versus mail-based written instruction in facilitating high-risk human papillomavirus (hrHPV) self-collection among post-menopausal patients compared with pre-menopausal patients, as well as the impact on acceptability and feasibility. METHODS: We conducted a prospective, randomized study of people eligible for cervical cancer screening, stratified by menopausal status, to undergo standard written or telehealth-based instructions for hrHPV self-collection. English speaking individuals residing in Oregon, with a cervix, eligible for primary hrHPV testing, and with access to a video-capable device were included. Patients with prior hysterectomy, trachelectomy, diagnosis of cervical cancer, or pelvic radiation for gynecologic cancer were excluded. We compared preference for and opinions about self-collection and hrHPV test results, by randomization group and stratified by menopausal status using descriptive statistics. RESULTS: Among 123 patients enrolled, 61 identified as post-menopausal with a median age of 57 years. While the majority of post-menopausal participants who received telehealth instructions found it helpful, only 6.1% considered telehealth instructions necessary to complete self-testing. There was no difference in opinion of telehealth by menopausal status. Overall, 88.5% of post-menopausal participants preferred self-collection to provider-collection. There were no significant differences between pre- and post-menopausal participants in terms of test preference, discomfort, ease of use, or perceptions of self-collection. CONCLUSION: Telehealth instruction did not add significant value to patients participating in hrHPV self-collection, nor did it alter the acceptability of hrHPV-self collection among an English-speaking cohort. Compared with prior experiences with provider-collected screening, hrHPV self-collection was preferred by both pre- and post-menopausal participants. There were no significant differences in preference for provider- versus self-collection when stratified by menopausal status.

Menstrual Health Literacy among Adolescents and Young Adults Who Menstruate: Impact of Christian Family Background and United States Region.

STUDY OBJECTIVE: To compare menstrual health literacy among adolescents and young adults on the basis of family religious background and United States region METHODS: We conducted a cross-sectional online survey of post-menarcheal US adolescents and young adults aged 14-24 years who identified their family religious background, including Christian or non-religious, with recruitment via the social media platform TikTok. We asked participants several questions to assess their health literacy regarding common myths about the use of gonadal steroid hormones for menstrual suppression. RESULTS: From 3250 online survey respondents, 2997 met the criteria for analysis, with 1989 identifying their family as Christian (66.4%) and 1008 identifying their family as non-religious (33.6%), with equal representation by US region. Health literacy was lower among those with a Christian family background, with concerns that menstrual suppression is unhealthy (16.4% vs 10.5% with non-religious background, P < .01), is unsafe (31.4% vs 24.2%, P < .01), and could lead to infertility (32.6% vs 20.0%, P < .01). Similarly, adolescents and young adults from the US South were worried that menstrual suppression is unhealthy (31.5%; P < .01) and would lead to infertility (33.8%; P < .01). CONCLUSION: Health literacy is lower among adolescents and young adults with a Christian family background and those who live in the South. These results demonstrate a need for an evidence-based national curriculum that addresses the safe and effective use of hormonal medications for menstrual suppression.

Association of State Funding for Comprehensive Reproductive Health Care With Use of Contraception Among Latina Patients and Non-Latina Patients in Oregon.

Importance: There are well-documented racial and ethnic disparities in effective contraceptive use due to multiple factors. A key contributor may be differential insurance coverage and patient costs. The Oregon Reproductive Health Equity Act (RHEA), enacted in 2017, ensures full coverage of reproductive health care without cost sharing for all Oregonians with low income. Objective: To assess whether removing financial barriers to accessing contraceptive care is associated with an improvement in use of moderately and highly effective contraceptive methods among Latina women compared with non-Latina women. Design, Setting, and Participants: This cohort study included women aged 12 to 51 years who sought contraceptive care in the Oregon Health Authority Reproductive Health Program from April 2016 to March 2020. Patients using permanent contraception, those missing data on ethnicity, and non-Oregon residents were excluded. Data analysis was performed in January 2021. Exposures: Contraceptive care in the Reproductive Health Program after RHEA implementation. Main Outcomes and Measures: The main outcome was prevalence of use of moderately effective methods (contraceptive pills, patch, ring, or injection) or highly effective methods (long-acting reversible contraceptives) at the time of the contraceptive visit. Difference-in-differences analysis was used to compare moderately and highly effective contraception use between Latina and non-Latina patients. Secondary outcomes were proportions of adoption or continuation of moderately and highly effective methods, prevalence of highly effective methods, and adoption or continuation of highly effective methods. The unit of analysis was at the clinic visit level. Results: The study sample consisted of 295 604 evaluable clinic visits, in which 28.4% of individuals identified as Latina and 71.6% of individuals identified as non-Latina. The mean (SD) age was 25.5 (8.1) years. With difference-in-differences analysis, there was a significant adjusted 1.9 percentage point (95% CI, 0.2-3.6 percentage points) increase in prevalence of moderately or highly effective contraceptive methods for Latina patients compared with non-Latina patients. There were no significant differences for other outcomes of interest. Conclusions: This cohort study found that in Oregon, legislation removing financial barriers to accessing contraceptive care was associated with significant mitigation in disparate moderately and highly effective contraceptive method prevalence for Latina patients compared with non-Latina patients. The findings suggest that state funds successfully supplanted federal funds to enable continued robust comprehensive family planning services after withdrawal from Title X.

Development and validation of an expanded panel of progestins using liquid chromatography-tandem triple quadrupole mass spectrometry to monitor protocol compliance in hormonal contraceptive pharmacokinetic/pharmacodynamic studies.

We developed and validated the use of ultra-high-performance liquid chromatography-heated electrospray ionization-tandem triple quadrupole mass spectrometry to simultaneously analyze serum concentrations of ethinylestradiol, dienogest, norelgestromin, norethindrone, gestodene, levonorgestrel, etonogestrel, segesterone acetate, medroxyprogesterone acetate, and drospirenone. The calibration range for all targets was 0.009-10 ng/mL, with lower limit of quantification of 0.009 ng/mL for all analytes except gestodene (0.019 ng/mL). We used our assay to check compliance among participants in a clinical trial, confirmed the use of drospirenone in 11 of 13 study participants, and evidence of noncompliant progestins in 2 (levonorgestrel = 1, norethindrone = 1). We conclude that this approach provides an accurate method to check protocol compliance in contraceptive clinical trials. IMPLICATIONS: The availability of a liquid chromatography-tandem triple quadrupole mass spectrometry multiprogestin analysis panel for simultaneous evaluation of the most common contraceptive steroids approved worldwide could improve monitoring of compliance and protocol adherence in clinical trials.

Impact of coronavirus disease 2019 (COVID-19) vaccination on menstrual bleeding quantity: An observational cohort study.

OBJECTIVE: To assess whether coronavirus disease 2019 (COVID-19) vaccination impacts menstrual bleeding quantity. DESIGN: Retrospective cohort. SETTING: Five global regions. POPULATION: Vaccinated and unvaccinated individuals with regular menstrual cycles using the digital fertility-awareness application Natural Cycles°. METHODS: We used prospectively collected menstrual cycle data, multivariable longitudinal Poisson generalised estimating equation (GEE) models and multivariable multinomial logistic regression models to calculate the adjusted difference between vaccination groups. All regression models were adjusted for confounding factors. MAIN OUTCOME MEASURES: The mean number of heavy bleeding days (fewer, no change or more) and changes in bleeding quantity (less, no change or more) at three time points (first dose, second dose and post-exposure menses). RESULTS: We included 9555 individuals (7401 vaccinated and 2154 unvaccinated). About two-thirds of individuals reported no change in the number of heavy bleeding days, regardless of vaccination status. After adjusting for confounding factors, there were no significant differences in the number of heavy bleeding days by vaccination status. A larger proportion of vaccinated individuals experienced an increase in total bleeding quantity (34.5% unvaccinated, 38.4% vaccinated; adjusted difference 4.0%, 99.2% CI 0.7%-7.2%). This translates to an estimated 40 additional people per 1000 individuals with normal menstrual cycles who experience a greater total bleeding quantity following the first vaccine dose' suffice. Differences resolved in the cycle post-exposure. CONCLUSIONS: A small increase in the probability of greater total bleeding quantity occurred following the first COVID-19 vaccine dose, which resolved in the cycle after the post-vaccination cycle. The total number of heavy bleeding days did not differ by vaccination status. Our findings can reassure the public that any changes are small and transient.

Reproductive Scientist Development Program: Bridging the Gap to the Physician Scientist Career.

Career development awards are a successful strategy to facilitate the advancement of physician-scientists trained in obstetrics and gynecology (OBGYN) toward a path of investigative independence. While these funding mechanisms can be effective approaches to developing the career of future OBGYN scientists, optimizing the probability of obtaining these awards requires determining the appropriate career development award for the applicant. There are many details and opportunities that need to be considered when deciding on the appropriate award. Some of the most sought-after awards are those that integrate career development and applied research, such as the K-series awards supported by the National Institutes of Health (NIH). A quintessential example of an NIH-funded mentor-based career development award to support the scientific training of an OBGYN physician-scientist is the Reproductive Scientist Development Program (RSDP). In this study, we provide data on the academic achievements of past and present RSDP scholars and discuss the structure, impact, and future of the RSDP, a federally funded K12 program dedicated to women's health for OBGYN scientific investigators. As healthcare is changing and physician-scientists comprise a unique and valuable part of the biomedical workforce, programs such as the RSDP are critical to maintaining a well-trained pipeline of OBGYN scientists to maintain and challenge the leading edge of medicine, science, and biology.

Cessation of chronic delta-9-tetrahydrocannabinol use partially reverses impacts on male fertility and the sperm epigenome in rhesus macaques.

OBJECTIVE: To determine whether discontinuation of delta-9-tetrahydrocannabinol (THC) use mitigates THC-associated changes in male reproductive health using a rhesus macaque model of daily THC edible consumption. DESIGN: Research animal study. SETTING: Research institute environment. PATIENT(S): Adult male rhesus macaques (age, 8-10 years; n = 6). INTERVENTION(S): Chronic daily THC edible administration at medically and recreationally relevant contemporary doses followed by cessation of THC use. MAIN OUTCOME MEASURE(S): Testicular volume, serum male hormones, semen parameters, sperm deoxyribonucleic acid (DNA) fragmentation, seminal fluid proteomics, and whole genome bisulfite sequencing of sperm DNA. RESULT(S): Chronic THC use resulted in significant testicular atrophy, increased gonadotropin levels, decreased serum sex steroid levels, changes in seminal fluid proteome, and increased DNA fragmentation with partial recovery after discontinuation of THC use. For every increase of 1 mg/7 kg/day in THC dosing, there was a significant decrease in the total testicular volume bilaterally by 12.6 cm3 (95% confidence interval [CI], 10.6-14.5), resulting in a 59% decrease in volume. With THC abstinence, the total testicular volume increased to 73% of its original volume. Similarly, with THC exposure, there were significant decreases in the mean total testosterone and estradiol levels and a significant increase in the follicle-stimulating hormone level. With increasing THC dose, there was a significant decrease in the liquid semen ejaculate volume and weight of coagulum; however, no other significant changes in the other semen parameters were noted. After discontinuing THC use, there was a significant increase in the total serum testosterone level by 1.3 ng/mL (95% CI, 0.1-2.4) and estradiol level by 2.9 pg/mL (95% CI, 0.4-5.4), and the follicle-stimulating hormone level significantly decreased by 0.06 ng/mL (95% CI, 0.01-0.11). Seminal fluid proteome analysis revealed differential expression of proteins enriched for processes related to cellular secretion, immune response, and fibrinolysis. Whole genome bisulfite sequencing identified 23,558 CpGs differentially methylated in heavy-THC vs. pre-THC sperm, with partial restoration of methylation after discontinuation of THC use. Genes associated with altered differentially methylated regions were enriched for those involved in the development and function of the nervous system. CONCLUSION(S): This is the first study demonstrating that discontinuation of chronic THC use in rhesus macaques partially restores adverse impacts to male reproductive health, THC-associated sperm differentially methylated regions in genes important for development, and expression of proteins important for male fertility.

Web-Based Yoga-Pilates: A Prospective Cohort Study.

IMPORTANCE: There are limited data to determine the change in severity, efficacy, and mechanism of action of yoga-Pilates in the treatment of stress urinary incontinence (SUI). OBJECTIVES: The primary objective was to evaluate the effect of an 8-week web-based home yoga-Pilates exercise program on SUI severity and to evaluate the potential mechanism of action through ultrasound examination of the urethral rhabdosphincter cross-sectional area. STUDY DESIGN: This was a prospective cohort study of women with SUI. Participants underwent visits pre- and post-intervention, completed quality of life/severity surveys, and underwent pelvic examination and 3-dimensional transperineal ultrasonography to determine the urethral cross-sectional area. Pre- and post-intervention 24-hour voiding diaries were also collected. The intervention was an 8-week online yoga-Pilates video that tracked and prompted participation. RESULTS: Sixty women completed the study; they were predominantly premenopausal (67%) and vaginally parous (65%) and had done yoga (76%) and/or Pilates (44%). Seventy-three percent performed the exercises ≥3 times per week. For the primary outcome, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score improved from 9.5 (95% confidence interval [CI], 8.7-10.4) to 7.1 (95% CI, 6.3-7.9) (P < 0.001). The median (interquartile range) number of incontinence episodes per 24 hours decreased from 1 (1-3) to 1 (0-1) (P < 0.001). The Brink pelvic floor strength score improved from 7.1 (95% CI, 6.6-7.7) to 7.7 (95% CI, 7.2-8.2) (P = 0.01). Eighty-three percent reported that they were "better" on Patient Global impression of Improvement. There were no significant changes in urethral measurements. CONCLUSIONS: Although it did not meet the minimal clinically important difference, this 8-week web-based yoga-Pilates exercise program improved SUI symptoms and decreased the number of incontinence episodes in women with SUI.

Chronic prenatal delta-9-tetrahydrocannabinol exposure adversely impacts placental function and development in a rhesus macaque model.

Cannabis use in pregnancy is associated with adverse perinatal outcomes, which are likely mediated by the placenta. However, the underlying mechanisms and specific vasoactive effects of cannabis on the placenta are unknown. Our objective was to determine the impact of chronic prenatal delta-tetrahydrocannabinol (THC, main psychoactive component of cannabis) exposure on placental function and development in a rhesus macaque model using advanced imaging. Animals were divided into two groups, control (CON, n = 5) and THC-exposed (THC, n = 5). THC-exposed animals received a THC edible daily pre-conception and throughout pregnancy. Animals underwent serial ultrasound and MRI at gestational days 85 (G85), G110, G135 and G155 (full term is ~ G168). Animals underwent cesarean delivery and placental collection at G155 for histologic and RNA-Seq analysis. THC-exposed pregnancies had significantly decreased amniotic fluid volume (p < 0.001), placental perfusion (p < 0.05), and fetal oxygen availability (p < 0.05), all indicators of placental insufficiency. Placental histological analysis demonstrated evidence of ischemic injury with microinfarctions present in THC-exposed animals only. Bulk RNA-seq demonstrated that THC alters the placental transcriptome and pathway analysis suggests dysregulated vasculature development and angiogenesis pathways. The longer-term consequences of these adverse placental findings are unknown, but they suggest that use of THC during pregnancy may deleteriously impact offspring development.

Association between menstrual cycle length and covid-19 vaccination: global, retrospective cohort study of prospectively collected data.

OBJECTIVES: To identify whether covid-19 vaccines are associated with menstrual changes in order to address concerns about menstrual cycle disruptions after covid-19 vaccination. DESIGN: Global, retrospective cohort study of prospectively collected data. SETTING: International users of the menstrual cycle tracking application, Natural Cycles. PARTICIPANTS: 19 622 individuals aged 18-45 years with cycle lengths of 24-38 days and consecutive data for at least three cycles before and one cycle after covid (vaccinated group; n=14 936), and those with at least four consecutive cycles over a similar time period (unvaccinated group; n=4686). MAIN OUTCOME MEASURES: The mean change within individuals was assessed by vaccination group for cycle and menses length (mean of three cycles before vaccination to the cycles after first and second dose of vaccine and the subsequent cycle). Mixed effects models were used to estimate the adjusted difference in change in cycle and menses length between the vaccinated and unvaccinated. RESULTS: Most people (n=15 713; 80.08%) were younger than 35 years, from the UK (n=6222; 31.71%), US and Canada (28.59%), or Europe (33.55%). Two thirds (9929 (66.48%) of 14 936) of the vaccinated cohort received the Pfizer-BioNTech (BNT162b2) covid-19 vaccine, 17.46% (n=2608) received Moderna (mRNA-1273), 9.06% (n=1353) received Oxford-AstraZeneca (ChAdOx1 nCoV-19), and 1.89% (n=283) received Johnson & Johnson (Ad26.COV2.S). Individuals who were vaccinated had a less than one day adjusted increase in the length of their first and second vaccine cycles, compared with individuals who were not vaccinated (0.71 day increase (99.3% confidence interval 0.47 to 0.96) for first dose; 0.56 day increase (0.28 to 0.84) for second dose). The adjusted difference was larger in people who received two doses in a cycle (3.70 days increase (2.98 to 4.42)). One cycle after vaccination, cycle length was similar to before the vaccine in individuals who received one dose per cycle (0.02 day change (99.3% confidence interval -0.10 to 0.14), but not yet for individuals who received two doses per cycle (0.85 day change (99.3% confidence interval 0.24 to 1.46)) compared with unvaccinated individuals. Changes in cycle length did not differ by the vaccine's mechanism of action (mRNA, adenovirus vector, or inactivated virus). Menses length was unaffected by vaccination. CONCLUSIONS: Covid-19 vaccination is associated with a small and likely to be temporary change in menstrual cycle length but no change in menses length.

Patterns in Contraceptive Use Among Women of Mexican Origin in the United States and in Mexico.

OBJECTIVE: To examine current contraceptive use by parity among four ethnicity and nativity groups: non-Latina White women in the United States, Mexican-American women in the United States, foreign-born women of Mexican origin in the United States, and Mexican women in Mexico. METHODS: We combined nationally representative data from sexually active women, aged 15-44 years, and not seeking pregnancy from the U.S. National Survey of Family Growth and the Mexican National Survey of Demographic Dynamics. This is a secondary binational analysis. Using multivariable logistic regression, we estimated the prevalence of moderately or most effective contraceptive method use (compared with least effective or no contraceptive method) by ethnicity and nativity and tested the interaction between ethnicity and nativity and parity. RESULTS: Compared with non-Latina White women, women of Mexican origin had lower odds of using a moderately or most effective contraceptive method (adjusted odds ratio [aOR] [95% CI] Mexican-American women: 0.69 [0.54-0.87]; foreign-born women: 0.67 [0.48-0.95]; Mexican women in Mexico: 0.59 [0.40-0.87]). Among parous women, the adjusted probability of using a moderately or most effective contraceptive method was approximately 65% among all four groups. Contraceptive method use did not differ by parity among non-Latina White women. However, parous Mexican-American women were 1.5 times more likely to use moderately or most effective contraceptive methods than nulliparous Mexican-American women (adjusted probability 66.1% vs 42.7%). Parous foreign-born women were 1.8 times more likely to use most or moderately effective contraceptive methods than their nulliparous counterparts (64.5% vs 36.0%), and parous Mexican women in Mexico were three times more likely to use moderately or most effective contraceptive methods (65.2% vs 21.5%). CONCLUSION: Findings suggest that access to effective contraception is limited outside the context of childbearing for women of Mexican origin in the United States and, to an even larger extent, in Mexico.

Association of Title X clinic status with receipt of person-centered contraceptive counseling: A population-based study.

OBJECTIVE: To describe receipt of person-centered contraceptive counseling among reproductive-aged women in the United States who sought contraceptive care at Title X clinics, non-Title X public clinics, and private clinics. STUDY DESIGN: We conducted a secondary analysis of the 2017-2019 wave of the National Survey of Family Growth (NSFG). The sample included female respondents ages 15-49 who received contraceptive services in the past year and completed the Person-Centered Contraceptive Counseling (PCCC) measure, a quality metric evaluating interpersonal quality of the care received. We used multivariable logistic regression to estimate the predicted probability of receiving person-centered contraceptive counseling by source of care, adjusted for individual-level characteristics. RESULTS: Of 2225 (weighted n = 26,599,620) eligible respondents, 6.9% received care at a Title X clinic, 8.2% at a non-Title X public clinic, and 84.9% at a private clinic. The adjusted predicted probability of receiving person-centered contraceptive counseling among respondents attending private clinics was 50.6% (95% CI 46.3%-54.8%) compared with 51.3% (95% CI 40.4%-62.3%) at Title X clinics and 52.4% (95% CI 44.0%-60.7%) at other public clinics. Respondents with incomes ≥300% above the federal poverty level (FPL) had higher odds of reporting receipt of person-centered counseling compared to those with incomes below 100% of the FPL (aOR = 2.12; 95% CI 1.47-3.06). Non-Latina Black respondents had lower odds of receiving person-centered contraceptive counseling (aOR = 0.69; 95% CI 0.51-0.94), compared to non-Latina white respondents. CONCLUSION: Title X clinics perform as well as the private sector in delivering person-centered contraceptive counseling. IMPLICATIONS: Title X clinics provide quality person-centered contraceptive counseling on par with the private sector, despite serving populations that are often less likely to report high quality care. Broad implementation of the PCCC measure will permit tracking person-centered contraceptive care across diverse practice settings and populations.

The Impact of Local Estrogen on the Urogenital Microbiome in Genitourinary Syndrome of Menopause: A Randomized-Controlled Trial.

IMPORTANCE: The postmenopausal urinary bladder microbiome is not well defined. OBJECTIVES: The aims of this study were to characterize the effect of vaginal estrogen on the vaginal and urinary bladder microbiome in postmenopausal women and describe any clinical associations with the symptoms of genitourinary syndrome of menopause. STUDY DESIGN: This was a participant-masked, randomized controlled trial comparing the effect of a 12-week course of an estrogen-containing vaginal ring to a placebo vaginal ring. Standardized evaluations were performed at baseline and 12 weeks. Vaginal samples were obtained for pH, vaginal maturation index, and microbiome analysis. Concomitant catheterized urine samples were obtained for microbiome analysis. 16S ribosomal RNA gene sequencing was performed to characterize the resident microbial communities, with Lactobacillus relative abundance as the primary outcome variable. Genitourinary syndrome of menopause symptoms was measured using validated questionnaires (Pelvic Floor Distress Inventory-Short Form, Female Sexual Function Index, Vulvovaginal Symptoms Questionnaire). RESULTS: Of the 39 postmenopausal women randomized, baseline characteristics were similar between arms, with a mean age of 62 years and mean vaginal pH of 5.0. Using intention-to-treat analysis, there were no significant changes in vaginal or urinary Lactobacillus relative abundance. Two participants in each arm removed their ring prior to the end of the study. Eighty percent of participants experienced at least 1 bothersome genitourinary syndrome of menopause symptom. Vulvovaginal dryness and urinary frequency were most common at baseline, whereas painful intercourse and urinary urgency were most common at the final visit, none of which were statistically significant. CONCLUSIONS: Our study did not show a significant change in the bacterial composition of the vaginal or urinary bladder microbiome after either vaginal ring in this relatively asymptomatic postmenopausal population.

A Randomized Trial of Social Media Versus Search Engine Advertising to Increase Awareness of Treatments for Female Stress Urinary Incontinence.

IMPORTANCE: Outreach based on user characteristics through social media advertising is significantly more effective than outreach based on user interests with search engine advertising for female stress urinary incontinence. OBJECTIVE: The aim of the study was to compare the effectiveness of 2 online outreach platforms to engage women at risk of stress urinary incontinence with a high-quality patient education website. STUDY DESIGN: A geographic randomized trial was performed comparing online advertising on Facebook, a social media site, versus Google Ads, a search engine, to direct viewers to VoicesForPFD.org. Advertisements were developed using health communication theory and pretested before the randomized trial. Counties in the Pacific Northwest were grouped into approximately equal populations, called "supercounties," and randomized to advertisement platforms. Educational website views resulting from each campaign, called sessions, were measured using Google Analytics; the primary outcome was the number of sessions per supercounty. County characteristics were obtained from national survey data. Effectiveness of the advertising platforms was compared between randomization arms using Welch's unequal variances t test, and crude and adjusted linear regression models. RESULTS: Mean user sessions were significantly higher in areas randomized to Facebook advertising (470 sessions) compared with areas randomized to Google Ads advertising [44 sessions; mean, 426 session difference (95% confidence interval, 199-653 sessions); P = 0.001]. After accounting for adult female population and rurality, randomization to Facebook instead of Google Ads still resulted in 409 additional sessions (95% confidence interval, 317-501 sessions; P < 0.001). CONCLUSIONS: Social media was 10 times more effective (470 versus 44 mean sessions per supercounty) than search engine outreach advertising and should be prioritized in outreach efforts. Future work is needed on engagement and behavior change with online outreach.

Chronic exposure to delta-9-tetrahydrocannabinol impacts testicular volume and male reproductive health in rhesus macaques.

OBJECTIVE: To determine the dose-dependent effect of delta-9-tetrahydrocannabinol (THC) exposure on male testes and reproductive health in a nonhuman primate model. DESIGN: Research animal study. SETTING: Research institute. ANIMAL(S): Adult male rhesus macaques 8-10 years of age (n = 6). INTERVENTION(S): Daily edible THC at medically and recreationally relevant doses. MAIN OUTCOME MEASURE(S): Testicular volume and epididymal head width, serum levels of inhibin B, albumin, total testosterone, prolactin, follicle-stimulating hormone, estradiol, and luteinizing hormone; semen volume; and sperm motility, morphology, and concentration. RESULT(S): For each 1 mg/7 kg/day increase in THC dosing, there was a marked loss in total bilateral testicular volume of 11.8 cm3 (95% confidence interval [CI]: 8.3-15.4). In total, average bilateral testicular volume decreased by 58%. Significant dose-response decreases in mean total testosterone level by 1.49 ng/mL (95% CI: 0.83-2.15) and in estradiol level by 3.8 pg/mL (95% CI: 2.2-5.4) were observed, but significant increases in the levels of follicle-stimulating hormone by 0.06 ng/mL (95% CI: 0.02-0.10), luteinizing hormone by 0.16 ng/mL (95% CI: 0.08-0.25), and prolactin by 7.4 ng/mL (95% CI: 3.4-11.3) were observed. There were no statistically significant changes in semen parameters. CONCLUSION(S): In rhesus macaques, chronic exposure to THC resulted in significant dose-response testicular atrophy, increased serum gonadotropin levels, and decreased serum sex steroids, suggestive of primary testicular failure. Further studies are needed to determine if reversal of these observed adverse effects would occur if THC was discontinued and for validation of thefindings in a human cohort.
