Abstract
BACKGROUND The US Food and Drug Administration-approved segesterone acetate and ethinyl estradiol ring-shaped contraceptive vaginal system, known as Annovera (Sever Pharma Solutions/QPharma, Malmö, Sweden), was inserted and removed under a woman's control for a 21 day in and 7 day out regimen for up to 13 cycles of use. OBJECTIVE We aimed to describe the patterns of ring expulsion over time, to identify potential predictors of expulsion, and to evaluate the impact of expulsions on method discontinuation and pregnancy risk. STUDY DESIGN Using data from 2064 participants who were enrolled in 2 multinational phase 3 clinical trials on the use of this contraceptive vaginal system, we examined data from participants' daily diaries for documentation of complete ring expulsion. We modeled the odds of reported expulsions over time with adjustment for background and demographic characteristics using mixed-effects logistic regression models with random intercepts. We compared the probability of continuation between those who did and those who did not report expulsions in the first cycle of use using survival analysis and hazards modeling. To determine if expulsions during the first cycle of use affected the risk for pregnancy, we calculated Pearl Indices. RESULTS Most participants (75%) never experienced any expulsions during any cycle of use, and 91% to 97% did not experience an expulsion during any 1 cycle. The incidence of expulsion was highest in cycle 1 (9%). The odds of experiencing expulsions decreased by half in cycles 2 to 8 when compared with cycle 1 (0.48; 95% confidence interval, 0.40-0.58), and in cycles 9 to 13, expulsions were about a third of that in cycle 1 (0.32; 95% confidence interval, 0.26-0.41). Of those who did experience expulsions, most (62%-84%) experienced ≤2 expulsions per cycle. Participants from study sites in Latin America vs those in the United States had higher odds of not experiencing an expulsion (odds ratio, 1.95; 95% confidence interval, 1.45-2.63). Women with a higher education level had higher odds of experiencing an expulsion. Notably, parity, age, and body mass index were not associated with expulsion. Participants who experienced any expulsions in cycle 1 were more likely to discontinue use early (hazard ratio, 1.28; 95% confidence interval, 1.14-1.43) than participants who did not have an expulsion. The Pearl Index for participants who had expulsions during cycle 1 was 3.99 (95% confidence interval, 1.29-9.31), which was higher than that among participants who reported no expulsions (Pearl Index, 2.39; 95% confidence interval, 1.61-3.41), but the overlapping confidence intervals indicate that there is not sufficient evidence to demonstrate an association between expulsions and pregnancy risk. CONCLUSION Expulsions were infrequent overall, decreased with subsequent cycles of use, and were not associated with body mass index or parity. Early discontinuation of product use was higher among participants who experienced an expulsion during cycle 1. Although it is unclear whether pregnancy risk was associated with expulsions, early recognition of expulsions among users may identify those at higher risk for discontinuation and may highlight when enhanced anticipatory counselling and guidance may be advantageous.

Abstract
BACKGROUND Confounding introduced by individuals' sexual risk behavior is potentially a significant source of bias in HIV-1 prevention intervention studies. To more completely account for sexual behaviors when assessing the efficacy of the monthly dapivirine ring, a new longer-acting HIV-1 prevention option for women, we estimated per-sex-act risk reduction associated with product use. METHODS We conducted a secondary analysis of data from MTN-020/ASPIRE, a phase 3, randomized, placebo-controlled efficacy trial of the dapivirine ring that recruited HIV-uninfected, African women aged 18-45 years. With cumulative sex acts as the time scale, we used multivariable Cox regression with inverse probability of censoring weights to estimate HIV-1 risk reduction associated with a rate of dapivirine release indicative of consistent product use. RESULTS Women in the dapivirine ring group (n = 1187) had an estimated incidence rate of 2.3 (95% confidence interval [CI], 1.8-3.1) HIV-1 acquisition events per 10 000 sex acts versus 3.6 (95% CI, 2.9-4.4) per 10 000 acts in the placebo group (n = 1187). Dapivirine release indicative of consistent ring use was associated with a 63% (95% CI, 33%-80%) per-sex-act HIV-1 risk reduction. CONCLUSIONS These results support the efficacy of the dapivirine vaginal ring for HIV-1 prevention and help to inform decision-making for women, providers, and policymakers regarding product use.

Abstract
INTRODUCTION Tenofovir-based oral pre-exposure prophylaxis is currently approved for HIV prevention; however, adherence in women has been low. A vaginal gel containing tenofovir (TFV) demonstrated partial protection to HIV but protection was not confirmed in additional studies. Vaginal rings offer user-controlled long-acting HIV prevention that could overcome adherence and protection challenges. TFV may also help prevent herpes simplex virus type 2 acquisition when delivered intravaginally. We evaluated the pharmacokinetics, safety, adherence and acceptability of a 90-day TFV ring. METHODS Between January and June 2019, Microbicide Trials Network (MTN)-038 enrolled 49 HIV-negative participants into a phase 1, randomized (2:1) trial comparing a 90-day ring containing 1.4 grams (g) TFV to a placebo ring. TFV concentrations were quantified in plasma, cervicovaginal fluid (CVF), rectal fluid and cervical tissue, and TFV-diphosphate (TFV-DP) in cervical tissue. Used rings were analysed for residual TFV. Safety was assessed by adverse events (AEs); acceptability and adherence by self-report. RESULTS Mean age was 29.5; 46 identified as cisgender-female and three gender non-conforming. There were no differences in the proportion of participants with grade ≥2 genitourinary AEs in the TFV versus placebo arms (p = 0.41); no grade ≥3 AEs were reported. Geometric mean TFV concentrations increased through day 34 in CVF/rectal fluid and day 59 in plasma, but declined across compartments by day 91. Geometric mean TFV-DP tissue concentrations exceeded the 1000 fmol/mg target through day 56, but fell to 456 fmol/mg at day 91. Among 32 rings returned at the end of the study, 13 had no or low (<0.1 g) residual TFV. Residual TFV did not differ by socio-demographics, sexual activity, Nugent Score or vaginal microbiota. Most participants reported being fully adherent to ring use: 85% and 81% in the TFV and placebo arms, respectively (p = 1.00). A majority of participants reported liking the ring (median 8 on a 10-point Likert scale) and reported a high likelihood of using the ring in the future, if effective (median 9). CONCLUSIONS The 90-day TFV ring was well-tolerated, acceptable and exceeded target cervical tissue concentrations through day 56, but declined thereafter. Additional studies are needed to characterize the higher release from TFV rings in some participants and the optimal duration of use.

Abstract
BACKGROUND Delivering contraceptive hormones through a transdermal patch or a vaginal ring might have advantages over the traditional oral route. OBJECTIVES To compare the effectiveness, compliance, and side effect profile of oral and parenteral drug administration methods. METHODS We performed a systematic literature search in four medical databases-MEDLINE (via PubMed), Cochrane Library (CENTRAL), Embase, and Scopus-from inception to 20 November 2022. Randomized controlled trials assessing the efficacy, compliance, and adverse event profile of combined parenteral and oral hormonal contraceptives were included. RESULTS Our systematic search provided 3952 records; after duplicate removal, we screened 2707 duplicate-free records. A total of 13 eligible studies were identified after title, abstract, and full-text selection. We observed no significant difference in contraceptive efficacy (Pearl Index) between oral and parenteral drug administration (MD = -0.06, CI: -0.66-0.53; I2 = 0%). We found significant subgroup differences between parenteral methods in terms of compliance (χ2 = 4.32, p =0.038, I2 = 80%) and certain adverse events: breast discomfort (χ2 = 19.04, p =0.001, I2 = 80%), nausea (χ2 = 8.04, p =0.005, I2 = 75%), and vomiting (χ2 = 9.30, p =0.002; I2 = 72%). CONCLUSION Both parenteral and oral contraceptives can be used as an effective contraceptive method, and the route of administration should be tailored to patient needs and adverse event occurrence.

Abstract
We assessed if acceptability of the dapivirine vaginal ring for HIV prevention differed among the subgroup of women who reported engaging in transactional sex prior to enrollment in MTN-020/ASPIRE (phase III trial in Malawi, South Africa, Uganda, and Zimbabwe, 2012-2015; n = 2629). Transactional sex was defined as receipt of money, goods, gifts, drugs, or shelter in exchange for sex in the past year. Dimensions of acceptability included: ease of use and physical sensation in situ, impacts on sex, partner's opinion, and likelihood of future use. We used Poisson regression models with robust standard errors to compare risk of acceptability challenges by baseline history of transactional sex. At product discontinuation, women exchanging sex found the ring comfortable (90%), easy to insert (92%) and nearly all (96%) were likely to use the ring in the future. Women who had exchanged sex were more likely to report feeling the ring during sex (ARR 1.43, 95% CI: 1.09, 1.89; p = 0.01) and slightly more likely to mind wearing the ring during menses (ARR 1.22, 95% CI: 1.01, 1,46; p = 0.04) and during sex (ARR 1.22, 95% CI: 1.02, 1.45; p = 0.03). Messaging and counseling should include enhanced support for use during sex and menses to support optimal use.

Abstract
OBJECTIVE This study aimed to evaluate the safety and acceptability of two fixed-dose 28-day vaginal ring formulations of 17β-estradiol (E2) and progesterone (P4) to treat vasomotor symptoms (VMS) and the genitourinary syndrome of menopause. DESIGN DARE HRT1-001 was the first-in-woman study of 28-day exposure to two 28-day intravaginal rings (IVRs) designed to release 80 µg/day E2 + 4 mg/day P4 (IVR1) or 160 µg/day E2 + 8 mg/day P4 (IVR2) compared with oral E2 1 mg/day + oral P4 100 mg/day. To assess safety, participants completed a daily diary to record treatment emergent adverse events (TEAEs). To determine acceptability, at the end of treatment IVR users completed a questionnaire assessing tolerability and usability. RESULTS Enrolled women (n = 34) were randomized to use IVR1 (n = 10), IVR2 (n = 12) or oral (n = 12). Thirty-one participants (IVR1 = 10, IVR2 = 10, oral = 11) completed the study. The TEAE profile of those in the IVR groups were similar to the referent oral regimen. TEAEs related to the study product were more common with IVR2 use. Endometrial biopsies were not performed unless endometrial thickness was >4 mm or for clinically significant postmenopausal bleeding. One IVR1 participant had an endometrial stripe increase from 4 mm at screening to 8 mm at the end of treatment. The biopsy indicated no evidence of plasma cells or endometritis and no evidence of atypia, hyperplasia or malignancy. Two other endometrial biopsies were performed for postmenopausal bleeding with similar findings. There were no clinically meaningful laboratory or vital sign abnormalities or trends identified in observed values or changes from baseline. Pelvic speculum examination identified no clinically significant abnormalities in any participant at any visit. Tolerability and usability data demonstrated that both IVRs were generally highly acceptable. CONCLUSIONS Both IVR1 and IVR2 were safe and well tolerated in healthy postmenopausal women. TEAE profiles were comparable to the referent oral regimen.

Abstract
Three-dimensional printing technologies can be implemented for the fabrication of personalized vaginal rings (VRs) as an alternative approach to traditional manufacturing. Although several studies have demonstrated the potential of additive manufacturing, there is a lack of knowledge concerning the opinions of patients and clinicians. This study aimed to investigate the perception of women and gynecologists regarding VRs with personalized shapes. The devices were printed with different designs (traditional, "Y", "M", and flat circle) by Fused Deposition Modeling for a cross-sectional survey with 155 participants. Their anticipated opinion was assessed through a questionnaire after a visual/tactile analysis of the VRs. The findings revealed that most women would feel comfortable using some of the 3D-printed VR designs and demonstrated good acceptability for the traditional and two innovative designs. However, women presented multiple preferences when the actual geometry was assessed, which directly related to their age, previous use of the vaginal route, and perception of comfort. In turn, gynecologists favored prescribing traditional and flat circle designs. Overall, although there was a difference in the perception between women and gynecologists, they had a positive opinion of the 3D-printed VRs. Finally, the personalized VRs could lead to an increase in therapeutic adherence, by meeting women's preferences.

Abstract
Introduction With high concurrent global rates of HIV incidence and unintended pregnancy, there is a need to provide options beyond condoms to enable users to simultaneously prevent HIV acquisition and pregnancy. Multiple vaginal rings are in development as "MPTs" (multipurpose prevention technologies) as they are shown to provide several co-occurring benefits such as discretion, convenience, reversibility and user control. Methods In this Phase 1 trial of a 3-month MPT ring in the U.S., 25 participants (low-risk for HIV and pregnancy) were randomized to use the study ring for 90 days continuously or in 28-day cycles with 2-day removal periods in between. All participants completed in-depth interviews at the end of their study participation. Results Overall, the ring was well tolerated. Participants resoundingly endorsed the concept of an extended-use, dual-purpose vaginal ring, but reported too many functional challenges and side effects to endorse this particular ring. Participants assigned to the continuous regimen reported more positive experiences with ring use than those in the cyclic group. A minority of participants who experienced minimal side effects and did not experience challenges with vaginal retention of the ring found it appealing. However, the majority of participants experienced challenges (ring slippage, expulsions, side effects, vaginal bleeding changes) with product use that outweighed the potential benefits and led them to report that - in the future - they would not be interested in using this specific version of the ring in its current form. A subset expressed interest in using the current MPT ring under certain conditions (e.g., if fewer expulsions, less bleeding, higher risk for HIV/pregnancy). Discussion User feedback regarding participant experiences and challenges with the study ring was continuously shared with the product developer, underscoring the value of early-stage end-user feedback in product development.

Abstract
There are controversial debates regarding the effects of contraceptive vaginal ring devices on females' sexual function. Therefore, the meta-analysis of before-after was conducted on the intervention studies published in the past years to clarify these contradictions. The existing literature on the subject was reviewed by searching through such databases as PubMed, Scopus, ISI Web of Sciences, Embase, Cochrane Library and Google Scholar up to July 2021. Before-after intervention studies that had examined the effect of vaginal rings on females' sexual function were collected as well. In total, five studies with 369 participants were included in quantitative syntheses. Pooled results from the random-effect model showed that NuvaRing had a positive effect on females' sexual function three months after insertion (WMD: 2.48; 95% CI: 0.30, 4.67; P = 0.026); however, this effect was not significant after 6 months (WMD: 4.38; 95% CI: -4.95, 13.72; P = 0.357). Meta-regression analysis suggested that the effect of this device is associated with users' age and body mass index 3 months after insertion. No publication bias was found by Egger's test or funnel plots. Overall, the results of this meta-analysis support the view that vaginal ring use is associated with a positive effect on the sexual function of women 3 months after insertion, while the effect of this device on the sexual function of women was insignificant after 6 months. However, given the dearth of available data, it is not possible to reach a definite conclusion on the effect of vaginal rings on females' sexual function.

Abstract
Combined Hormonal Contraception - Which Pill for Which Patient? Abstract. Combined hormonal contraceptives (CHC) are a valuable and highly effective option in contraceptive counseling. Methods and preparations available in Switzerland are combined oral contraceptives (COC), vaginal rings and transdermal patches. All preparations contain an estrogen and a progestin component. The estrogen component mainly consists of the synthetically produced ethinylestradiol (EE), although newer COC may contain natural estrogens such as estradiol (E2) and estetrol (E4). For the progestin component, a variety of luteal body hormones are available, which enable the health care professional to prescribe a "tailored" product for the patient due to their different partial effects. The individual thromboembolism (TE) risk should always be considered and taken into account when prescribing CHC.

Abstract
BACKGROUND Persistent use of HIV prevention methods can be a challenge, particularly for some younger women. The long-acting, discreet, woman-centric dapivirine vaginal ring offers promise as a prevention method with less user burden, which could support continued use. We assessed dapivirine vaginal ring use to understand adherence patterns and identify characteristics influencing patterns. SETTING Participants enrolled in South Africa in the MTN-020/ASPIRE randomized placebo-controlled trial. METHODS We used group-based trajectory modeling to identify clusters of participants with similar longitudinal patterns of adherence in the last year of participation and potential predictors of group membership. Women with at least 1 year of follow-up were included (n = 626). RESULTS Five adherence patterns were identified: (1) consistently high, 34%, (2) consistently moderate, 34%, (3) consistently low, 16%, (4) decreasing, 9%, and (5) increasing, 7%. Women younger than 22 years [adjusted odds ratio (AOR) 1.8, 95% confidence interval (CI): 1.0 to 3.0], using an intrauterine device (AOR 3.3, 95% CI: 1.4 to 7.8) or oral contraceptives (AOR 3.9, 95% CI: 1.7 to 8.9), experiencing menses (AOR 1.8, 95% CI: 1.1 to 3.0), and who reported inconsistent condom use (AOR 1.8, 95% CI: 1.0 to 3.3) were more likely to be classified as consistently low compared to consistently high (referent). CONCLUSIONS Most South African women successfully persisted with a moderate or high level of use. Encouraging ring replacement with completion of menses may help to decrease concerns about hygiene and improve persistence. Associations between contraception and persistent low adherence suggest efforts may be needed to ensure contraceptive method choice does not interfere with ring use.

Abstract
Oral Pre-Exposure Prophylaxis (PrEP) is an established option, and the dapivirine vaginal ring is emerging as a promising strategy for HIV prevention option for women. Because of this, understanding the contextual and cultural factors that will support the increased uptake of these products is crucial. In sub-Saharan Africa, religious leaders may be important stakeholders to involve in product information, education and roll-out. We conducted a sub-analysis of data from 232 participants taking part in the MTN-041/MAMMA study to explore religious leaders' involvement in pregnant and breastfeeding women's health. Study participants viewed biomedicine and spirituality as interlinked and believed that women could seek health-related care from medical experts and turn to faith-based organisations for religious or spiritual needs. Religious leaders were invested in the health of their congregations, endorsed a variety of sexual health strategies, and were eager to learn more about emerging HIV prevention technologies. These data signal the role of religious leaders in supporting their communities, and the importance of involving religious leaders in efforts to roll out new HIV prevention products to facilitate uptake.

Abstract
Background: Women worldwide face risks from pregnancy, HIV, and other sexually transmitted infections (STIs). To date, highly effective contraceptive methods provide no HIV/STI protection, and HIV prevention products, excluding condoms, provide no pregnancy protection. Intravaginal rings (IVRs) delivering antiretrovirals and contraceptives are a promising multipurpose prevention technology (MPT). Methods: Embedded within a Phase I randomized, placebo-controlled trial, we examined acceptability of continuous versus interrupted use of a 90-day MPT IVR among 47 low-risk women in Norfolk, Virginia and the Dominican Republic. A baseline survey assessed menstruation attitudes, risk perceptions and trial-related motivations. Follow-up surveys (M1/M3) examined user experiences with and preferences for IVR attributes; 18 women also participated in two in-depth interviews. Results: Most women rated the IVR's flexibility and smoothness (86%) and ease of insertion/removal (76%) as very acceptable. Fewer women similarly rated the IVR size (57%) and changes in color from menstruation (52%). Most participants experienced no changes or less bleeding. Those reporting more/heavier bleeding (20% M1, 15% M3) disliked the change. Overall, women preferred a 3-month (75%) to a 1-month IVR (7.5%) or a bimonthly injectable (10%). In qualitative interviews, women were willing to continuously use an IVR for 6–12 months, providing it did not “degrade” inside the body. Reasons for trial participation and prevention preferences, menstrual attitudes, and perceived IVR benefits and doubts varied by site. Conclusions: Findings provide strong evidence of demand for an MPT IVR that protects from pregnancy and HIV/STIs, lasts longer than 1 month, minimally disrupts menstrual bleeding, and is in women's control. numberClinicalTrials.gov: #NCT03279120.

Abstract
BACKGROUND Contraception care is essential to providing comprehensive healthcare; however, little is known nationally about the contraception workforce. Previous research has examined the supply, distribution, and adequacy of the health workforce providing contraception services, but this research has faced a series of data limitations, relying on surveys or focusing on a subset of practitioners and resulting in an incomplete picture of contraception practitioners in the United States. OBJECTIVE This study aimed to construct a comprehensive database of the contraceptive workforce in the United States that provides the following 6 types of highly effective contraception: intrauterine device, implant, shot (depot medroxyprogesterone acetate), oral contraception, hormonal patch, and vaginal ring. In addition, we aimed to examine the difference in supply, distribution, the types of contraception services offered, and Medicaid participation. STUDY DESIGN We constructed a national database of contraceptive service providers using multiple data sets: IQVIA prescription claims, preadjudicated medical claims, and the OneKey healthcare provider data set; the National Plan and Provider Enumeration System data set; and the Census Bureau's American Community Survey data on population demographics. All statistical analyses were descriptive, including chi-squared tests for groupwise differences and pairwise post hoc tests with Bonferroni corrections for multiple comparisons. RESULTS Although 73.1% of obstetrician-gynecologists and 72.6% of nurse-midwives prescribed the pill, patch, or ring, only 51.4% of family medicine physicians, 32.4% of pediatricians, and 19.8% of internal medicine physicians do so. The ratio of all primary care providers prescribing contraception to the female population of reproductive age (ages, 15-44 years) varied substantially across states, with a range of 27.9 providers per 10,000 population in New Jersey to 74.2 providers per 10,000 population in Maine. In addition, there are substantial differences across states for Medicaid acceptance. Of the obstetrician-gynecologists providing contraception, the percentage of providers who prescribe contraception to Medicaid patients ranged from 83.9% (District of Columbia) to 100% (North Dakota); for family medicine physicians, it ranged from 49.7% (Florida) to 91.1% (Massachusetts); and for internal medicine physicians, it ranged from 25.0% (Texas) to 75.9% (Delaware). For in-person contraception, there were large differences in the proportion of providers offering the 3 different contraceptive method types (intrauterine device, implant, and shot) by provider specialty. CONCLUSION This study found a significant difference in the distribution, types of contraception, and Medicaid participation of the contraception workforce. In addition to obstetrician-gynecologists and nurse-midwives, family medicine physicians, internal medicine physicians, pediatricians, advanced practice nurses, and physician assistants are important contraception providers. However, large gaps remain in the provision of highly effective services such as intrauterine devices and implants. Future research should examine provider characteristics, programs, and policies associated with the provision of different contraception services.

Abstract
BACKGROUND A 25 mg dapivirine vaginal ring has been demonstrated to reduce risk of HIV acquisition in nonpregnant adult women. In this secondary analysis of studies conducted in US adolescent, lactating, and postmenopausal females, vaginal microbiota was assessed prior to and after ring use, and between dapivirine and placebo ring users. METHODS Vaginal fluid swabs were collected before and after product use for the evaluation of microbiota using Nugent's criteria, quantitative culture, and qPCR. RESULTS Vaginal ring use did not impact bacterial vaginosis prevalence among the three populations and was associated with minimal shifts in microbiota. Adolescents in both arms demonstrated an increased prevalence of Lactobacillus crispatus and a decrease in quantity of Megasphaera lornae. Postmenopausal active and placebo ring users demonstrated an increased prevalence of lactobacilli and non-albicans yeast while dapivirine ring users demonstrated an increased prevalence of Candida albicans, and increased quantity of Group B Streptococcus (GBS) and non-albicans yeasts. Prevotella species were increased in lactating women while P. timonensis increased in prevalence and concentration among adolescent and postmenopausal women and P. bivia increased in prevalence among adolescent dapivirine ring users. CONCLUSIONS Dapivirine vaginal ring use was associated with minimal changes in the vaginal microbiota that are likely not clinically significant.

Abstract
Vaginal drug delivery systems can provide a long-term and constant liberation of the active pharmaceutical ingredient even for months. For our experiment, FDM 3D printing was used to manufacture the vaginal ring samples from thermoplastic polyurethane filament, which enables fast manufacturing of complex, personalized medications. 3D printing can be an excellent alternative instead of industrial manufacturing, which is complicated and time-consuming. In our work, the 3D printed vaginal rings were filled manually with jellified metronidazole or chloramphenicol for the treatment of bacterial vaginosis. The need for manual filling was certified by the thermogravimetric and heatflow assay results. The manufactured samples were analyzed by an Erweka USP type II Dissolution Apparatus, and the dissolution profile can be distinguished based on the applied jellifying agents and the API's. All samples were considered non-similar based on the pairwise comparison. The biocompatibility properties were determined by prolonged MTT assay on HeLa cells, and the polymer could be considered non-toxic. Based on the microbiological assay on E. coli metronidazole and chitosan containing samples had bactericidal effects while just metronidazole or just chitosan containing samples bacteriostatic effect. None of these samples showed a fungistatic or fungicide effect against C. albicans. Based on our results, we successfully manufactured 3D printed vaginal rings filled with jellified metronidazole.

Abstract
OBJECTIVE This study aims to assess the product-related, relationship-related, and sex-related factors that act as facilitators and barriers to the acceptability of a vaginal ring (VR) for HIV prevention among adolescent girls. DESIGN Qualitative study. METHODS Ninety-six girls aged 15-17 years from 6 urban US sites were enrolled in MTN-023/IPM 030, a 24-week randomized controlled trial, for assessing the safety and acceptability of a dapivirine VR for HIV prevention. At week 24, 21 girls were randomly selected to participate in in-depth interviews. Interviews were transcribed verbatim and data analyzed using a thematic analysis approach. Facilitators and barriers to VR acceptability related to participants' relationships, sexual activity, and characteristics of the VR product were identified. RESULTS Factors related to relationships rarely seemed to act as barriers to VR acceptability; most participants disclosed VR use to sexual partners, and positive reactions from sexual partners, which were common, seemed to facilitate VR acceptability. Emotional and/or physical discomfort surrounding VR use during sex was mentioned occasionally as a barrier to VR acceptability. Product characteristics were most frequently mentioned as barriers to VR acceptability. Many participants reported concerns about the large size of the VR on first impression. Although most found the VR comfortable, some reported pain with VR insertion. Several participants were concerned about VR cleanliness, particularly during menstruation. CONCLUSION Product considerations, specifically size and use during menstruation, were the most commonly reported barriers to VR acceptability in this study. Adolescent girls may require additional counseling to assuage product concerns regarding a VR for HIV prevention.

Abstract
The aim was to assess the pharmacokinetics of tolterodine released from vaginal rings and of its active metabolite 5-hydroxymethyl tolterodine (5-HMT) compared to the respective pharmacokinetics resulting from oral administration of extended-release tolterodine in healthy, postmenopausal women. In this single-center, open-label trial, subjects received 4 treatments in a fixed sequence: fasted oral extended-release tolterodine 2.74 mg/d (reference, 5 days), single vaginal rings; tolterodine releasing rates: 0.95 mg/d (test 1, 13 days), 1.40 mg/d (test 2, 28 days), 1.90 mg/d (test 3, 28 days). Systemic exposure of tolterodine, 5-HMT, and the molar sum of unbound tolterodine/5-HMT (active moiety [AM]) in steady state was determined. Sixteen of 18 included women completed the study. For the oral formulation, peak-trough fluctuations of tolterodine, 5-HMT, and AM plasma concentrations (AM: mean maximum/minimum concentration, 2580/574 pmol/L = 4.5) were large. Intravaginal application led to steadier plasma concentrations (AM, test 3: mean maximum/minimum concentration, 1880/814 pmol/L = 2.3; fluctuation due to initial peak), which is the result of constant releasing rates after ring insertion over the 28-day application period. The vaginal rings demonstrated a favorable local tolerability. The most common adverse events with oral and vaginal tolterodine were headache (n = 11) and dry mouth (n = 8). Vaginal rings releasing tolterodine represent a promising new formulation for overactive bladder treatment with little fluctuation of drug plasma levels. This is expected to lead to a more predictable and continuous therapeutic effect and a reduced frequency of side effects compared to oral tolterodine.

Abstract
INTRODUCTION Vaginal rings are a promising approach to provide a woman-centred, long-acting HIV prevention strategy. Prior trials of a 25 mg dapivirine (DPV) ring have shown a favourable safety profile and approximately 30% risk reduction of HIV-1 infection. Extended duration rings replaced every three months may encourage user adherence, improve health service efficiency and reduce cost overall. We evaluated safety, pharmacokinetics, adherence and acceptability of two three-month rings with different DPV dosages, compared with the monthly DPV ring. METHODS From December 2017 to October 2018, MTN-036/IPM-047 enrolled 49 HIV-negative participant in Birmingham, Alabama and San Francisco, California into a phase 1, randomized trial comparing two extended duration (three-month) rings (100 or 200 mg DPV) to a monthly 25 mg DPV ring, each used over 13 weeks, with follow-up completed in January 2019. Safety was assessed by recording adverse events (AEs). DPV concentrations were quantified in plasma, cervicovaginal fluid (CVF) and cervical tissue, at nominal timepoints. Geometric mean ratios (GMRs) relative to the comparator ring were estimated from a regression model. RESULTS There were no differences in the proportion of participants with grade ≥2 genitourinary AEs or grade ≥3 AEs in the extended duration versus monthly ring arms (p = 1.0). Plasma and CVF DPV concentrations were higher in the extended duration rings compared to the monthly ring. Plasma GMRs were 1.31 to 1.85 and 1.41 to 1.86 and CVF GMRs were 1.45 to 2.87 and 1.74 to 2.60 for the 100 and 200 mg ring respectively. Cervical tissue concentrations were consistently higher in the 200 mg ring (GMRs 2.36 to 3.97). The majority of participants (82%) were fully adherent (ring inserted at all times, with no product discontinuations/outages) with no differences between the monthly versus three-month rings. Most participants found the ring acceptable (median = 8 on 10-point Likert scale), with a greater proportion of participants reporting high acceptability (9 or 10) in the 25 mg arm (73%) compared with the 100 mg (25%) and 200 mg (44%) arms (p = 0.01 and p = 0.15 respectively). CONCLUSIONS The extended duration DPV rings were well-tolerated and achieved higher DPV concentrations compared with the monthly DPV ring. These findings support further evaluation of three-month DPV rings for HIV prevention.

Abstract
PURPOSE To evaluate the pharmacokinetics and pharmacodynamics of oestriol (E3) and trimegestone (TMG) in healthy women after application of three different vaginal rings over 21 days. The vaginal rings had a nominal delivery rate of 0.413/0.050 mg/day (Test 1), 0.311/0.090 mg/day (Test 2) and 0.209/0.137 mg/day (Test 3) E3/TMG. METHODS Thirty-five healthy women were randomised to receive a single application of Test 1, 2 or 3 (Clinical Trial NCT03343912). The E3 and TMG plasma concentration was determined by LC-MS/MS. Oestradiol (E2) and progesterone (PG) serum concentrations, and bleeding patern were determined as pharmacodynamic parameters. Safety was assessed by evaluation of adverse events and local tolerability. RESULTS The total and maximum exposure of E3 and TMG increased in a proportional ratio to dose. However, not in a magnitude which was expected from the dose differences for E3. During Test 2 and 3 treatment all E2 and PG values remained on a well suppressed level until end of treatment. E2 and PG serum levels increased distinctly earlier after ring removal with Test 1 compared to Test 2 and 3. Test 3 achieved 95.24% of "no bleeding" days under treatment followed by Test 1 (91.67%), and Test 2 (86.15%). CONCLUSIONS The Test 3 formulation presented the best dose combination of E3/TMG for contraception. Moreover, all vaginal rings were well tolerated.

Abstract
OBJECTIVE The antiretroviral-based dapivirine vaginal ring reduced HIV risk among women in phase III clinical trials. However, limited data exists on the impact of dapivirine on the vaginal microenvironment in adolescents. DESIGN A comprehensive metaproteomics approach was used to assess host proteome and microbiome changes in cervicovaginal mucus with dapivirine ring use in adolescents enrolled in the MTN-023/IPM 030 (MTN-023) trial. METHODS Participants were randomized 3 : 1 to use dapivirine or placebo vaginal rings monthly for 6 months. Cervicovaginal samples from a subset of 35 participants (8 placebo, 27 dapivirine) were analyzed. RESULTS Mass spectrometry analysis identified 405 human and 2467 bacterial proteins belonging to 15 unique genera. The host proteome belonged to many functional pathways primarily related to inflammation. When stratified by study treatment arm, 18 (4.4%) and 28 (6.9%) human proteins were differentially abundant (adjusted P < 0.05) between baseline and follow-up in the placebo and dapivirine arms, respectively. The vaginal microbiome was predominantly composed of Lactobacillus, Gardnerella, and Prevotella. Although bacterial taxa did not differ by arm or change significantly, Lactobacillus crispatus increased (P < 0.001) and Lactobacillus iners decreased (P < 0.001) during the 6-month follow-up. There were no significant differences in bacterial functions by arm or time in the trial. Protected vaginal sex significantly associated with decreased neutrophil inflammatory biomarkers and may be associated with changes in bacterial taxa and metabolism. CONCLUSION Condom use may associate with differences to inflammation and bacterial function but dapivirine ring use does not, thereby supporting the mucosal safety profile of this vaginal ring for adolescents.

Abstract
INTRODUCTION Pharmacotherapy has a key role in the management of endometriosis. However, a significant proportion of patients gains only intermittent or limited benefits. In this regard, alternative and novel drug delivery methods are of paramount importance to improve efficacy and compliance of available treatments and develop alternative medical approaches. AREAS COVERED This review aims to provide the reader with a complete overview of available evidence about alternative and novel drug delivery methods for endometriosis pharmacotherapy and highlight new research lines. EXPERT OPINION Progestins and estroprogestins, which represent the first-line therapy, are already available in different formulations, being employed for contraception. Nevertheless, evidence on their adoption is still limited for some drug delivery methods, such as vaginal rings, patches, and subcutaneous implants. Further research is needed to define better their clinical utility in patients with endometriosis. Nanotechnologies have been investigated as novel drug delivery methods able to target the drug at the disease level. However, data are very limited and preliminary, and further research is needed to consider a possible clinical application in endometriosis.

Abstract
The vaginal rings research is almost exclusively focused on rings for human medicine, although the dosage form offers improvement of therapeutic effect in other mammals as well. This contribution studied an effect of varying dimension parameters (diameter 20, 30 or 40 mm; height 3, 4 or 5 mm; width of annulus 5, 7.5 or 10 mm) on mechanical properties and dissolution behaviour of silicone vaginal rings with constant drug amount, intended for use in dogs. Results showed that altering dimensions influenced mechanical properties (compressive force, tensile strength and resistance of removal thread), in vitro drug release and water uptake. The removal thread resistance was increasing with increasing height and width. Compression force was higher for the rings with smaller diameter. The total drug release was increasing with decreasing height and rising diameter, surface area and water uptake during dissolution test. The initial dissolution rate was slower for the rings with higher width. As the best candidate for use in model dog subjects, the ring with 30 mm diameter, 3 mm height and 7.5 mm width was found. These drug-free vaginal rings were further tested in in vivo safety study. The results did not show any major deviation from the physiological conditions. Graphical abstract.

Abstract
OBJECTIVE To evaluate the evidence on the effectiveness of vaginal microbicides in preventing HIV transmission in women. METHODS Systematic review through a comprehensive search of relevant electronic databases for eligible randomised controlled trials (RCTs) published through June 2019. Two authors independently screened titles and abstracts according to eligibility criteria, then extracted data and assessed risk of bias of included studies. We conducted a random-effects meta-analysis of risk ratios (RR) of HIV infection and assessed heterogeneity using chi-squared and I2 tests. Sources of heterogeneity were investigated through subgroup analysis, publication bias was assessed using funnel plots, and certainty of evidence was graded using GRADEPro software. RESULTS We included 18 RCTs which enrolled 40,048 sexually active, HIV-negative, non-pregnant women, aged 16 years and older, mainly from sub-Saharan Africa. The intravaginal ring containing dapivirine significantly reduced HIV risk by 29% (RR 0.71, 95% CI: 0.57-0.89; 2 RCTs, 4,564 women, moderate certainty of evidence). Estimates of effect of tenofovir 1% (RR 0.83, 95% CI: 0.65-1.06), nonoxynol-9 (RR 1.15, 95% CI: 0.93-1.42), cellulose sulphate (RR 1.16, 95% CI: 0.61-2.21), SAVVY (RR 1.34, 95% CI: 0.69-2.59), Carraguard (RR 0.89, 95% CI: 0.71-1.10), BufferGel (RR 1.02, 95% CI: 0.71-1.46), 0.5% PRO2000 (RR 0.88, 95% CI: 0.60-1.28) and 2% PRO2000 (RR 0.81, 95% CI: 0.58-1.12) failed to reach statistical significance; each had low certainty of evidence. CONCLUSION The long-acting intravaginal ring containing dapivirine significantly reduced risk of HIV transmission in women by 29%. The remaining microbicides had no evident effect.

Abstract
OBJECTIVE We aimed to determine if the dapivirine vaginal ring and the ring device alone (flexible silicone matrix polymer) was associated with the development of cervical cytology abnormalities. DESIGN Secondary analysis comparing cervical cytology results between two randomized controlled microbicide trials (MTN-020/ASPIRE and MTN-003/VOICE). METHODS Data from ASPIRE, a phase III, placebo-controlled trial of the dapivirine vaginal ring, were used in this analysis. Cervical cytology smears were evaluated at baseline and at the final visit with product use. We compared cytology results between women randomized to dapivirine versus placebo vaginal ring. We further assessed for the effect of the vaginal ring device on cervical cytology by comparing results with data from the oral placebo arm of VOICE, a prior HIV-1 prevention trial conducted in a similar population. RESULTS Cervical cytology results for 2394 women from ASPIRE (1197 per study arm) were used in this analysis; median time between baseline and final visit with product use was 22.1 months. Cytology smear findings were comparable between dapivirine and placebo vaginal ring arms: at final visit, normal: 90.6 versus 91.5%, ASC-US//LSIL: 7.8 versus 7.4%, ASC-H/HSIL/AGC/AGC-favor neoplastic: 1.7 versus 1.1%, P = 0.44. Cytology data from VOICE had findings (normal: 87.8%, ASC-US/LSIL: 9.8%, ASC-H/HSIL/AGC/AGC-favor neoplastic: 2.4%) comparable with that of both dapivirine (P = 0.93) and placebo vaginal ring arms (P = 0.24). CONCLUSION These findings indicate that neither use of the dapivirine vaginal ring nor the vaginal ring device alone, over a period of 2 years, is associated with development of cervical cytology abnormalities that could lead to precancerous or cancerous lesions.

Abstract
Up to 85% of the US adult population carries herpes simplex virus type-1 (HSV-1), with a smaller percentage (22%) infected with HSV-2. Herpesviruses can survive in lytic phase, when the viruses are actively replicating, or in latency, when the virus is functionally dormant in ganglia. Among drugs to treat these infections is acyclovir (ACV). ACV exhibits poor oral bioavailability and a short in vivo half-life; only about 10-15% of ingested drug enters the bloodstream and its half-life is about 3 hours. With those disadvantages and the possibility of poor patient compliance, viral replication may not always be suppressed. To abrogate these shortcomings we propose local distribution via sustained drug release. We present a matrix-based antiherpetic ring, composed of poly(ethylene co-vinyl acetate), that releases ACV directly to the vaginal epithelium. A 30-day in vitro drug release trial showed that approximately 135 +/- 20 μg/day of ACV was consistently released. Rings were nontoxic in cell culture and suppressed primary HSV-1 and HSV-2 replication. We expect these data form the basis for novel interventions in human health, where new prophylactics and therapeutics against genital herpes are truly needed.

Abstract
Objective: The aim of the study was to evaluate whether the compositions of the ethylene vinyl acetate (EVA) membrane of two different contraceptive vaginal rings could influence the surface roughness, which is associated with the possible accumulation of vaginal biomass on the rings during use.Methods: We measured and compared the surface roughness of unused vaginal rings, NuvaRing and Ornibel, using a scanning electron microscope (SEM) and dedicated software that can convert SEM images into 3D models. Average roughness (Ra), average quadratic roughness (Rq) and mean height of the irregularities at 10 points (Rz) were calculated.Results: Different thicknesses of the EVA membranes between the two rings were noted. No significant differences were found between the two rings in the three evaluated values of surface roughness (NuvaRing vs Ornibel, respectively: Ra, 1.53 ± 0.14 vs 1.61 ± 0.14 µm, p = 0.141; Rq, 2.03 ± 0.25 vs 2.07 ± 0.16 µm, p = 0.688; Rz, 11.4 ± 3.1 vs 11.4 ± 2.4 µm, p = 0.987).Conclusion: The different composition of the vaginal rings' EVA membrane is not associated with different surface roughness. Ornibel is equivalent to NuvaRing in terms of surface roughness, despite the different composition of the membrane polymers.

Abstract
Rumours may influence health-related behaviours, including the uptake of and adherence to HIV prevention products. This study assessed the safety and effectiveness of a vaginal ring delivering the antiretroviral dapivirine for HIV prevention in Africa. We explored negative rumours about study participation and the vaginal ring amongst study participants and their communities in Malawi, Uganda, South Africa and Zimbabwe. In total 214 women participated in either single or serial in-depth interviews, or a focus group discussion. Three key findings emerged in the data. Firstly, rumours reflected fears concerning the ring and trial participation. Given the historical-political context of the countries in which the trial was conducted, the ring's investigational nature and its foreign origin, ring use was rumoured to cause negative health outcomes such as cancer and infertility and to be associated with practices such as witchcraft or Satanism. The salience of these rumours varied by country. Secondly, rumours reportedly affected participants' adherence to the ring, and other women's willingness to participate in the study. Finally, participants reported that participant engagement activities helped address rumours, resulting in enhanced trust and rapport between staff and participants.

Abstract
BACKGROUND Drug-drug interactions between orally administered antiretroviral therapy (ART) and hormones released from an intravaginal ring are not known. We hypothesised that ART containing either efavirenz or ritonavir-boosted atazanavir would alter plasma concentrations of vaginally administered etonogestrel and ethinylestradiol but that ART concentrations would be unchanged during use of an intravaginal ring. METHODS We did a parallel, three-group, pharmacokinetic evaluation at HIV clinics in Asia (two sites), South America (five), sub-Saharan Africa (three), and the USA (11) between Dec 30, 2014, and Sept 12, 2016. We enrolled women with HIV who were either ART-naive (control group; n=25), receiving efavirenz-based ART (n=25), or receiving atazanavir-ritonavir-based ART (n=24). Women receiving ART were required to be on the same regimen for at least 30 days, with 400 copies or less per mL of plasma HIV-1 RNA; women not receiving ART had CD4 counts of 350 cells per μL or less. We excluded participants who had a bilateral oophorectomy or conditions that were contraindicated in the intravaginal ring product labelling. An intravaginal ring releasing etonogestrel and ethinylestradiol was inserted at entry (day 0). Single plasma samples for hormone concentrations were collected on days 7, 14, and 21 after intravaginal ring insertion. The primary outcome was the plasma concentration of etonogestrel and ethinylestradiol on day 21. Etonogestrel and ethinylestradiol concentrations were compared between each ART group and the control group by geometric mean ratio (GMR) with 90% CIs and Wilcoxon rank-sum test. As secondary outcomes, efavirenz or ritonavir-boosted atazanavir concentrations were assessed by 8-h intensive pharmacokinetic sampling at entry before intravaginal ring insertion and before intravaginal ring removal on day 21. Antiretroviral areas under the concentration-time curve (AUC0-8 h) were compared before and after intravaginal ring insertion by GMR (90% CI) and Wilcoxon signed-rank test. This study is registered with ClinicalTrials.gov, number NCT01903031. FINDINGS Between Dec 30, 2014, and Sept 12, 2016, we enrolled 84 participants in the study; ten participants were excluded from the primary hormone analysis. 74 participants met the primary endpoint: 25 in the control group, 25 in the efavirenz group, and 24 in the atazanavir group. On day 21 of intravaginal ring use, participants receiving efavirenz had 79% lower etonogestrel (GMR 0·21, 90% CI 0·16-0·28; p<0·0001) and 59% lower ethinylestradiol (0·41, 0·32-0·52; p<0·0001) concentrations compared with the control group. By contrast, participants receiving ritonavir-boosted atazanavir had 71% higher etonogestrel (1·71, 1·37-2·14; p<0·0001), yet 38% lower ethinylestradiol (0·62, 0·49-0·79; p=0·0037) compared with the control group. The AUC0-8 h of efavirenz or atazanavir did not differ between the groups. INTERPRETATION Hormone exposure was significantly lower when an intravaginal ring contraceptive was combined with efavirenz-based ART. Further studies designed to examine pharmacodynamic endpoints, such as ovulation, when intravaginal ring hormones are combined with efavirenz are warranted.

Abstract
In recent decades, hormonal contraceptives (HC) has made a difference in the control of female fertility, taking an unequivocal role in improving contraceptive efficacy. Some side effects of hormonal treatments have been carefully studied. However, the influence of these drugs on female sexual functioning is not so clear, although variations in the plasma levels of sexual hormones could be associated with sexual dysfunction. Permanent hormonal modifications, during menopause or caused by some endocrine pathologies, could be directly related to sexual dysfunction in some cases but not in all of them. HC use seems to be responsible for a decrease of circulating androgen, estradiol, and progesterone levels, as well as for the inhibition of oxytocin functioning. Hormonal contraceptive use could alter women's pair-bonding behavior, reduce neural response to the expectation of erotic stimuli, and increase sexual jealousy. There are contradictory results from different studies regarding the association between sexual dysfunction and hormonal contraceptives, so it could be firmly said that additional research is needed. When contraceptive-related female sexual dysfunction is suspected, the recommended therapy is the discontinuation of contraceptives with consideration of an alternative method, such as levonorgestrel-releasing intrauterine systems, copper intrauterine contraceptives, etonogestrel implants, the permanent sterilization of either partner (when future fertility is not desired), or a contraceptive ring.

Abstract
In veterinary medicine, vaginal rings (VRs) are rarely used. However, there are diseases of female dogs' reproductive system which represent a suitable possibility for their usage. An example of such a disease is canine pyometra which can be treated by lipophilic prostaglandin drugs, unfortunately with harmful side effects after systemic administration. The aim of the study was to prove that the matrix VR based on silicone and channel-forming substance can be successfully used as a carrier for a three-day delivery of prostaglandin E2 (PGE2). Based on an in-vitro release study, an optimum channel-forming substance and its concentration were selected. The results were implemented during the construction of VR from the medical grade silicone DDU-4840 with PGE2 (5 mg). Glucose anhydrous in the 30% concentration was chosen as the most functional channel-forming substance due to synergism of osmotic activity and solubility. The DDU-VR containing PGE2 and 30% of glucose anhydrous exhibited excellent mechanical characteristics and ensured 29% drug release through water-filled channels in first-order kinetic manner. This is eight times higher than a sample without glucose where molecular diffusion through the silicone matrix was dominating the release mechanism. Moreover, drug-free VRs were tested for mechanical resistance and the design of removal thread.

Abstract
INTRODUCTION A vaginal ring containing dapivirine is effective for HIV prevention as pre-exposure prophylaxis (PrEP). We evaluated the potential epidemiological impact and cost-effectiveness of dapivirine vaginal ring PrEP among 22- to 45-year-old women in KwaZulu-Natal, South Africa. METHODS Using mathematical modelling, we studied dapivirine vaginal ring PrEP implementation, either unprioritized, or prioritized based on HIV incidence (≥3% per year), age (22 to 29 years) or female sex worker status, alongside the implementation of voluntary medical male circumcision and antiretroviral therapy scaled-up to UNAIDS Fast-Track targets. Outcomes over the intervention (2019 to 2030) and lifetime horizons included cumulative HIV infections, life-years lived, costs and cost-effectiveness. We assessed the incremental cost-effectiveness ratios against the revealed willingness to pay ($500) and the standard (2017 per capita gross domestic product; $6161) cost-effectiveness thresholds for South Africa. RESULTS Compared to a reference scenario without PrEP, implementation of dapivirine vaginal ring PrEP, assuming 56% effectiveness and covering 50% of 22 to 29-year-old or high-incidence women, prevented 10% or 11% of infections by 2030 respectively. Equivalent, unprioritized coverage (30%) prevented fewer infections (7%), whereas 50% coverage of female sex workers had the least impact (4%). Drug resistance attributable to PrEP was modest (2% to 4% of people living with drug-resistant HIV). Over the lifetime horizon, dapivirine PrEP implementation among female sex workers was cost-saving, whereas incidence-based PrEP cost $1898 per life-year gained, relative to PrEP among female sex workers and $989 versus the reference scenario. In a scenario of 37% PrEP effectiveness, PrEP had less impact, but prioritization to female sex workers remained cost-saving. In uncertainty analysis, female sex worker PrEP was consistently cost-saving; and over the lifetime horizon, PrEP cost less than $6161 per life-year gained in over 99% of simulations, whereas incidence- and age-based PrEP cost below $500 per life-year gained in 61% and 49% of simulations respectively. PrEP adherence and efficacy, and the effectiveness of antiretroviral therapy for HIV prevention, were the principal drivers of uncertainty in the cost-effectiveness of PrEP. CONCLUSIONS Dapivirine vaginal ring PrEP would be cost-saving in KwaZulu-Natal if prioritized to female sex workers. PrEP's impact on HIV prevention would be increased, with potential affordability, if prioritized to women by age or incidence.

Abstract
The U.S. Food and Drug Administration approved a new combination hormonal contraceptive in August 2018. Sold under the brand name Annovera, it is a combination of segesterone acetate and ethinyl estradiol, and it is the first multiuse vaginal contraceptive system that prevents ovulation for up to 13 menstrual cycles in a year. Although there are several combination hormonal contraceptives on the market, this is the first single system that can be repeatedly used for an entire year and does not require placement by a health care provider. This innovation gives women control over when to stop using the contraceptive, should they so desire. Annovera is stored at room temperature when not in use, allowing women living in uncontrolled-temperature climates to use one contraceptive method for an entire year.

Abstract
OBJECTIVE To assess patient experience and convenience of using progesterone vaginal ring (VR) versus vaginal gel for women requiring luteal phase support during in vitro fertilization (IVF). DESIGN Post hoc analysis of a prospective, randomized, single-blind, multicenter, phase 3 clinical trial. SETTING Twenty-two U.S. IVF centers. PATIENT(S) Women undergoing IVF (N = 1,297). INTERVENTION(S) Randomization to weekly VR or daily gel the day after egg retrieval for up to 10 weeks, with fresh embryo transfer IVF per site-specific procedures. MAIN OUTCOME MEASURE(S) Patient satisfaction questionnaire completed at final study visit. RESULT(S) In the women who were taking ≥1 dose of either VR (n = 647) or gel (n = 650), >97% reported that learning to use the formulation, remembering to take it at the correct time, and using it as prescribed was "easy" or "somewhat easy." More VR than gel users reported noninterference with daily activity (93.3% vs. 74.7%, P<.001), sexual comfort (80.3% vs. 67.8%, P<.001), and sexual desire (73.8% vs. 61.8%, P<.001), as well as not being bothered during sexual intercourse (66.9% vs. 39.2%, P<.001). More gel than VR users reported no difficulty with application (97.4% vs. 80.9%, P<.001). Among women who had previously used progesterone during IVF, more VR users than gel users preferred their currently assigned treatment to their previous treatment (91.4% vs. 83.0%, P=.03). CONCLUSION(S) Weekly progesterone VR and daily progesterone gel were easy to use, with limited impact on quality of life. Overall, the VR appeared to interfere less with daily life, social activities, and sexual activity although the gel was less difficult or stressful to apply. CLINICAL TRIAL REGISTRATION NUMBER NCT00615251.

Abstract
OBJECTIVE A systematic review was carried out of studies of women with endometriosis, to examine the evidence for efficacy of the use of hormonal contraception to improve disease-related pain and decrease postoperative risk of disease recurrence. METHODS A search of the Medline/PubMed and Embase databases was performed to identify all published English language studies on hormonal contraceptive therapies (combined hormonal contraceptives [CHCs], combined oral contraceptives [COCs], progestin-only pills [POPs] and progestin-only contraceptives [POCs]) in women with a validated endometriosis diagnosis, in comparison with placebo, comparator therapies or other hormonal therapies. Main outcome measures were endometriosis-related pain (dysmenorrhoea, pelvic pain and dyspareunia), quality of life (QoL) and postoperative rate of disease recurrence during treatment. RESULTS CHC and POC treatments were associated with clinically significant reductions in dysmenorrhoea, often accompanied by reductions in non-cyclical pelvic pain and dyspareunia and an improvement in QoL. Only two COC preparations (ethinylestradiol [EE]/norethisterone acetate [NETA] and a flexible EE/drospirenone regimen) demonstrated significantly increased efficacy compared with placebo. Only three studies found that the postoperative use of COCs (EE/NETA, EE/desogestrel and EE/gestodene) reduced the risk of disease recurrence. There was no evidence that POCs reduced the risk of disease recurrence. CONCLUSIONS CHCs and POCs are effective for the relief of endometriosis-related dysmenorrhoea, pelvic pain and dyspareunia, and improve QoL. Some COCs decreased the risk of disease recurrence after conservative surgery, but POCs did not. There is insufficient evidence, however, to reach definitive conclusions about the overall superiority of any particular hormonal contraceptive.

Abstract
INTRODUCTION Oral contraceptives could induce mood changes. As far as our knowledge, there are no studies in literature that have examined the role of vaginal contraception in self-perceived body image. AIM To evaluate the effects of intravaginal contraception on weight gain and perceived body image in relation with the Beck's Depression Inventory questionnaire (BDI) and the McCoy Female Sexuality Questionnaire (MFSQ). METHODS Twenty-one adult (18-35 years old) eumenorrheic (menstrual cycle of 25-35 days), lean (body mass index - BMI - of 19-25 kg/m2) women who were referred for hormonal contraception were administered the Stunkard Figure Rating Scale (FRS), BDI and MFSQ. Subjects were studied in basal condition and after 6 months of therapy with vaginal contraception (NuvaRing®; Organon-Schering-Plough Italia, Milan, Italy). MAIN OUTCOME MEASURES BMI, FRS, MFSQ and BDI. RESULTS After 6 months of therapy with NuvaRing®, both body weight (60.0 ± 8.3; p = 0.050) and BMI (22.1 ± 3.1; p = 0.028) slightly, but statistically, increased. FRS and BDI showed no differences after the vaginal contraception. Hormonal contraception was associated with a significant decrease in the two-factor Italian MFSQ score. CONCLUSIONS Vaginal ring seems a good alternative to other hormonal contraceptive not significantly altering the female sexuality and not influencing the FRS and BDI.

Abstract
The 2016 Conference on Retroviruses and Opportunistic Infections (CROI) highlighted hot spots in HIV infection. Men who have sex with men (MSM), transgender populations, people who inject drugs, fisherfolk, migrants, adolescents, and older adults are heavily impacted in a number of regions. Stigma contributes to risk behaviors and HIV acquisition across populations. HIV testing is a crucial first step in the HIV care continuum, and several large community-based surveys are underway in Africa to increase HIV testing, linkage to care, and uptake of antiretroviral treatment. Advances in preexposure prophylaxis (PrEP) featured prominently at CROI 2016. Two large efficacy trials of a vaginal ring containing the investigational drug dapivirine demonstrated efficacy and safety in preventing HIV infections in women in Africa. Data on the safety of long-acting injectable PrEP and several investigational PrEP drugs and formulations were also presented. Knowledge and use of PrEP among MSM in the United States appears to be increasing, and high uptake was seen among black MSM when provided as part of a culturally tailored support program. The use of broadly neutralizing antibodies for HIV prevention is a novel and promising approach to be evaluated in efficacy trials.

Abstract
INTRODUCTION Product adherence and its measurement have emerged as a critical challenge in the evaluation of new HIV prevention technologies. Long-acting ARV-based vaginal rings may simplify use instructions and require less user behaviour, thereby facilitating adherence. One ARV-based ring is in efficacy trials and others, including multipurpose rings, are in the pipeline. Participant motivations, counselling support and measurement challenges during ring trials must still be addressed. In previous HIV prevention trials, this has been done largely using descriptive and post-hoc methods that are highly variable and minimally evaluated. We outline an interdisciplinary framework for systematically investigating promising strategies to support product uptake and adherence, and to measure adherence in the context of randomized, blinded clinical trials. DISCUSSION The interdisciplinary framework highlights the dual use of adherence measurement (i.e. to provide feedback during trial implementation and to inform interpretation of trial findings) and underscores the complex pathways that connect measurement, adherence support and enacted adherence behaviour. Three inter-related approaches are highlighted: 1) adherence support - sequential efforts to define motivators of study product adherence and to develop, test, refine and evaluate adherence support messages; 2) self-reported psychometric measures - creation of valid and generalizable measures based in easily administered scales that capture vaginal ring use with improved predictive ability at screening, baseline and follow-up that better engage participants in reporting adherence; and 3) more objective measurement of adherence - real-time adherence monitoring and cumulative measurement to correlate adherence with overall product effectiveness through innovative designs, models and prototypes using electronic and biometric technologies to detect ring insertion and/or removal or expulsion. Coordinating research along these three pathways will result in a comprehensive approach to product adherence within clinical trials. CONCLUSIONS Better measurement of adherence will not, by itself, ensure that future effectiveness trials will be able to address the most basic question: if the product is used per instructions, will it prevent HIV transmission? The challenges to adherence measurement must be addressed as one component of a more integrated system that has as its central focus adherence as a behaviour emerging from the social context of the user.

Abstract
Background The first hormonal contraceptive was introduced onto the market in several countries 50 years ago; however, the portfolio of contraceptive methods remains restricted with regards to their steroid composition, their cost, and their ability to satisfy the requirements of millions of women/couples in accordance with their different reproductive intentions, behaviors, cultures, and settings. Methods A literature review was conducted using Medline, Embase, and Current Contents databases, up to September 1, 2013 to identify publications reporting new contraceptives in development using combinations of the search terms: contraception, contraceptives, oral contraceptives, patch, vaginal ring, implants, intrauterine contraceptives, and emergency contraception (EC). Also, several experts in the field were also consulted to document ongoing projects on contraception development. Additionally, the Clinicaltrial.gov website was searched for ongoing studies on existing contraceptive methods and new and emerging female contraceptives developed over the past 5 years. Information was also obtained from the pharmaceutical industry. Results Early sexual debut and late menopause means that women may require contraception for up to 30 years. Although oral, injectable, vaginal, transdermal, subdermal, and intrauterine contraceptives are already available, new contraceptives have been developed in an attempt to reduce side effects and avoid early discontinuation, and to fulfill women’s different requirements. Research efforts are focused on replacing ethinyl-estradiol with natural estradiol to reduce thrombotic events. In addition, new, less androgenic progestins are being introduced and selective progesterone receptor modulators and new delivery systems are being used. In addition, research is being conducted into methods that offer dual protection (contraception and protection against human immunodeficiency virus transmission), and contraceptives for use “on demand.” Studies are also investigating non-hormonal contraceptive methods that have additional, non-contraceptive benefits. Conclusion The most pressing need worldwide is, first, that the highly effective contraceptive methods already available should be affordable to most of the population and also that these methods should fulfill the needs of women of different ages and with different reproductive requirements. The development of new contraceptive methods should also take advantage of the knowledge obtained over the past 30 years on gamete physiology and gamete interaction to avoid the use of steroid compounds.

Abstract
Up to half of all postmenopausal women will experience changes in the genitourinary tract induced by the hypoestrogenic state, collectively known as vaginal atrophy. Vaginally administered local estrogen therapy (LET) is the standard of care for symptoms of vaginal atrophy that do not respond to nonhormonal interventions. Several LET formulations are available, and choice of therapy is based largely on patient needs and preferences. This online survey of postmenopausal LET users was conducted to investigate reasons for switching to vaginal estradiol tablets from other formulations and to evaluate factors associated with patient preference for and compliance with use of LET. Data was analyzed from 73 respondents currently using estradiol vaginal tablets who have previously used the estradiol vaginal ring, estradiol vaginal cream, and/or conjugated estrogen vaginal cream. Patients in this survey rated vaginal symptoms of vaginal atrophy as being more bothersome than urinary symptoms. Respondents preferred their current treatment with the vaginal tablet to their previous treatment with a cream or ring. The preference for tablets over creams was mainly related to formulation and application rather than to any perceived safety issues. Tablets were perceived as efficacious, convenient, and neat to apply. The study participants also reported a longer duration of tablet use compared with creams or rings, and greater compliance with vaginal tablets than with vaginal cream. This study provides new insights into reasons for patient noncompliance with estrogen cream or ring therapy that can be used to maximize patient adherence with LET.

Abstract
PURPOSE To describe women's condom use patterns over time and assess predictors of dual method use 12 months after initiating hormonal contraceptives. METHODS We conducted a prospective cohort study among women aged 15-24 years initiating oral contraceptive pills, patch, ring, or depot medroxyprogesterone and attending public family planning clinics. Participants completed questionnaires at baseline and 3, 6, and 12 months after enrollment. We used multivariable logistic regression to assess baseline factors associated with dual method use at 12 months among 1,194 women who were sexually active in the past 30 days. RESULTS At baseline, 36% were condom users, and only 5% were dual method users. After initiation of a hormonal method, condom use decreased to 27% and remained relatively unchanged thereafter. Dual method use increased to a peak of 20% at 3 months but decreased over time. Women who were condom users at baseline had nearly twice the odds of being a dual method user at 12 months compared with nonusers (adjusted odds ratio [AOR] = 2.01, 95% CI: 1.28-3.14). Women who believed their main partner thought condoms were "very important," regardless of perceived sexually transmitted infection risk or participant's own views of condoms, had higher odds of dual method use (AOR = 2.89, 95% CI: 1.47-5.71). CONCLUSIONS These results highlight a potential missed opportunity for family planning providers. Providers focus on helping women initiate hormonal methods, however, they may improve outcomes by giving greater attention to method continuation and contingency planning in the event of method discontinuation and to the role of the partner in family planning.

Abstract
The purpose of this review was to test contraceptive efficacy, cycle control, tolerability, and acceptability as found in the non-comparative studies with NuvaRing® by those found in the randomized trials comparing NuvaRing and combined oral contraceptives (COCs). All large non-comparative studies and all relevant randomized controlled trials (RCTs) between NuvaRing and a COC up to and including December 2006 were analyzed. Two large multi-center registration studies, 1 large daily clinical practice study, and 6 RCTs comparing NuvaRing and a COC were identified. The findings in the non-comparative studies were confirmed in the RCTs. Contraceptive efficacy was high showing no significant differences in comparison with the COC; cycle control was good and consistently better than that of the COC; compliance was high and comparable with that of the pill; the incidence of adverse events such as breast tenderness, headache, and nausea was low, but not lower than with the COC despite a halving of the systemic exposure to ethinyl estradiol (EE) with NuvaRing compared with a 30-μg EE-containing COC; the incidence of local and ring-related events was low but higher than with the COC, leading to higher discontinuation rates among NuvaRing users; acceptability was high and comparable between both contraceptives, resulting in a global improvement of sexual function with both methods. After study completion, women using NuvaRing were more likely to continue with their method than women using a COC. The good results with respect to contraceptive efficacy, cycle control, tolerability, and acceptability as achieved with NuvaRing in the large non-comparative registration studies were confirmed in the RCTs comparing NuvaRing with different COCs.

Abstract
Women and girls are especially vulnerable to HIV infection in sub-Saharan Africa, and in some of those countries, prevalence among young women can be up to 3 times higher than among men of the same age. Effective HIV prevention options for women are clearly needed in this setting. Several ARV-based vaginal microbicides are currently in development for prevention of HIV transmission to women and are discussed here. The concept of pre-exposure prophylaxis for the prevention of HIV transmission to women is introduced.

Abstract
The contraceptive vaginal ring is a novel contraceptive method that offers unique advantages. Intravaginal delivery of both estrogen and progesterone allows continuous release of medication, resulting in lower systemic levels. The use of long-term combined hormonal contraception enables improved cycle control compared with progesterone-only methods. The indications and usage of the NuvaRing® are described along with the efficacy, tolerability, and safety. Overall, the contraceptive vaginal ring appears to be very effective, with a favorable side-effect profile, and is highly acceptable to most patients.

Abstract
PURPOSE The vaginal ring and the transdermal patch offer important contraceptive options for women at high risk for unintended pregnancy. Little is known about what adolescents and young women think about these methods and why use of the ring has been relatively low compared with the patch. We sought to examine young women's attitudes and perceptions about the ring and the patch to better understand the relationship between perceptions of these methods and decisions to use them. METHODS Sixteen focus groups of young women aged 15-26 years (n=113) from family planning clinics in the San Francisco Bay Area were convened. Data from the focus groups were analyzed using standard content analysis. RESULTS Although young women expressed apprehension and doubt about both methods, for the most part women expressed more positive attitudes about the patch. Two related themes for the ring and the patch were identified: "lack of trust in effectiveness," and "method use concerns". Two themes unique to the ring ("concerns regarding vaginal insertion" and "sexual partner perceptions") and three themes unique to the patch ("ease of remembering," "visibility issues," and "perceived health risk") were identified. CONCLUSIONS Increased provider education about apprehensions related to the ring and the patch may lead to increased use of the ring and may counter recent declines in use of the patch. It would be unfortunate if these safe and effective options for young women were to be underused because negative attitudes and perceptions about these methods acted as barriers to adoption.

Abstract
PURPOSE To understand racial/ethnic minority adolescent females' experiences with the vaginal ring. METHODS We conducted in-depth interviews with a clinic-based sample of 32 young women aged 15-24 years who had used the vaginal ring. RESULTS Qualitative analysis using grounded theory revealed that adolescents undergo a multi-stage process when trying the ring and adopting ring use. These stages include hearing about the ring, initial reactions, first experiences with insertion and removal, and first sexual experiences. Adolescents subsequently enter an assessment and adjustment stage in which they decide whether to adopt or discontinue ring use. Ultimately they share their experiences with friends. CONCLUSIONS The model developed provides a context within which providers may advise adolescents as they begin use of the ring. Some specific recommendations are offered.

Abstract
STUDY OBJECTIVE To compare acceptability of the vaginal contraceptive ring to that of oral contraceptive pills. DESIGN Randomized, cross-over, 6-month study. SETTING Urban family planning clinic for young low-income patients. PARTICIPANTS Sexually active females aged 15-21 years (n = 130). INTERVENTIONS Participants were randomly assigned to use the vaginal ring or oral contraceptive pills for an initial study interval of three 28-day cycles, followed by three cycles of the alternate method. MAIN OUTCOME MEASURES Participants completed surveys about method use, acceptability, and side effects at baseline, after three cycles, and after six cycles. We analyzed study data using ANOVA models for cross-over designs. RESULTS We did not detect higher compliance with the ring as compared to oral contraceptive pills (P = 0.176), although overall approval of the ring was significantly higher on several items measured, including liked using method (P = 0.015), would recommend it to friends (P = 0.012), and not as hard to remember to use method correctly (P < or = 0.000). Participants were less worried about health risks while using the ring (P = 0.006), but reported that the ring was more likely to interfere with sex than the pill (P < or = 0.001) and that sex partners liked the pill (P = 0.034). Most women did not report bothersome side effects with either method. CONCLUSIONS Adolescent and young women showed favorable acceptability of the vaginal contraceptive ring compared to oral contraceptive pills.
