Abstract
Background The NuvaRing®, a hormonal vaginal contraceptive device, has gained widespread usage due to its favourable efficacy and safety profiles. Exceedingly rare instances of unintended misplacement in the bladder have been reported. This study presents a review of the literature and the first video report illustrating the extraction of an intravesical NuvaRing®, discussing diagnostic and therapeutic approaches. Objective To illustrate an effective method for intravesical NuvaRing® retrieval and raise awareness about this unusual complication. Materials and Methods A 27-year-old patient with low urinary tract symptoms related to NuvaRing® misplacement underwent diagnostic procedures, including ultrasound and diagnostic cystoscopy. A cystoscopic extraction under general anaesthesia was performed. Main outcome measures The effectiveness of pelvic ultrasound for diagnosing an intravesical foreign body, successful cystoscopic removal of NuvaRing® from the bladder, and symptom resolution were assessed. Results The intravesical NuvaRing® was identified through pelvic ultrasound. During cystoscopy, the ring was detected inside the bladder. Multiple attempts with cystoscopic alligator graspers were made; the NuvaRing® was eventually extracted using transurethral Heiss forceps. The patient experienced minimal blood loss and was discharged the following day, reporting relief from symptoms. Conclusions Unintentional NuvaRing® placement in the bladder is an extremely rare event that healthcare providers should consider when patients present with urinary symptoms and pelvic pain. Pelvic ultrasound is an efficient diagnostic tool, possibly averting the need for further imaging techniques. Cystoscopy remains the preferred method for diagnosis and treatment. This video report illustrates an effective technique for NuvaRing ® extraction, especially when appropriate graspers are unavailable. Adequate instruction on NuvaRing® insertion should always be emphasised.

Abstract
Contraception is a significant part of comprehensive sexual and reproductive health (SRH) care for adolescents and young adults (AYA). While providers may assume that AYA with chronic illness are not sexually active, studies have shown that there are no differences in their sexual practices compared to their counterparts without an illness. This assumption may result in less SRH screening, preventative services, and counseling by providers resulting in decreased basic sexual knowledge, increased risk of unplanned pregnancy, and other health disparities. Sexually active AYA with medical complexity are particularly in need of contraception for a variety of reasons. A better understanding of the complexities around contraception counseling can help increase utilization rates, improve shared-decision making around family planning, and reduce the stigma around sexual health counseling in this population. We have included three sections. First, a general overview of contraception methods. Next, an overview of contraceptive methods currently available, their efficacy, and medical eligibility criteria for their use in AYA who have certain characteristics or medical conditions. Finally, cases adapted from real clinical scenarios to highlight specific recommendations for contraception in AYA women living HIV, autoimmune conditions, and those who have received a solid organ transplant. This information will help providers to consider the multiple factors that influence contraception decision-making (including clinical status, thrombosis risk, medication interactions, safety), and optimize care for AYA living with chronic illness.

Abstract
PURPOSE To report a rare case of acute renal vein thrombosis (RVT) that was treated with endovascular thrombectomy and lysis, and discuss potential etiology and indications for catheter-directed management. CASE REPORT A 21-year-old female athlete presented with sudden pain in her left flank and vomiting. A 3-phase computed tomography (CT) angiogram identified total occlusion of the left renal vein with no excretion from the swollen tender left kidney. Catheter-directed thrombolysis and thrombectomy were initiated 24 hours after onset of symptoms. Complete resolution of the RVT with normalized renal function was achieved. Post-operative Doppler ultrasound scan confirmed normal renal resistance and flow in the renal vein. The patient was discharged on Apixaban and remains well at 6 months. Combined hormonal contraception via an intra-vaginal ring and raised Factor VIII activity were the only identified risk factors. CONCLUSION Acute complete RVT with impaired kidney function is rare. Combined hormonal contraception and increased Factor VIII activity were potential risk factors. Endovascular thrombectomy and lysis restored renal perfusion and function, and can be used effectively in the management of fit patients with acutely compromised kidney function from total renal vein obstruction.

Abstract
Contraception is a practice with extensive and complicated social and scientific histories. From cycle tracking, to the very first prescription contraceptive pill, to now having over-the-counter contraceptives on demand, family planning is an aspect of healthcare that has undergone and will continue to undergo several transformations through time. This review provides a comprehensive overview of current reversible hormonal and non-hormonal birth control methods as well as their mechanism of action, safety, and effectiveness specifically for individuals who can become pregnant. Additionally, we discuss the latest Food and Drug Administration (FDA)-approved hormonal method containing estetrol and drospirenone that has not yet been used worldwide as well as the first FDA-approved hormonal over-the-counter progestin-only pills. We also review available data on novel hormonal delivery through microchip, microneedle, and the latest FDA-approved non-hormonal methods such as vaginal pH regulators. Finally, this review will assist in advancing female contraceptive method development by underlining constructive directions for future pursuits. Information was gathered from the NCBI and Google Scholars databases using English and included publications from 1900 to present. Search terms included contraceptive names as well as efficacy, safety, and mechanism of action. In summary, we suggest that investigators consider the side effects and acceptability together with the efficacy of contraceptive candidate towards their development.

Abstract
The vaginal contraceptive ring is very effective and user dependent. In this article, we will discuss the different types of vaginal contraceptive rings, namely, the etonogestrel/ethinyl estradiol (ENG/EE) ring (NuvaRing, Merck, Rahway, NJ, USA) and the segesterone acetate (SA)/EE (Annovera, Mayne Pharma, Raleigh, NC, USA) ring. The details of dosing and administration, indications, advantages, disadvantages, and cost-effectiveness are presented. This literature review was conducted using PubMed and Google Scholar. The search terms included 'vaginal contraceptive ring', 'etonogestrel/ethinyl estradiol ring', and 'segesterone acetate/ethinyl estradiol ring'. The search was then sorted by year from 2000 until present, and the most recent articles were reviewed. The purpose of this article is to provide a comprehensive reference on the two vaginal contraceptive rings widely used in the United States for clinicians to guide management. Both vaginal contraceptive rings are combination of hormonal contraceptives that suppress ovulation and create physiologic conditions unfavorable for pregnancy. The ENG/EE ring is designed to be replaced monthly, while the SA/EE ring is a single device used over the course of 1 year. Common side effects of both devices include headaches, nausea, vomiting, and vaginitis. Serious adverse reactions can occur with the vaginal contraceptive rings including venous thromboembolism, psychiatric events, and hypersensitivity. Both devices are contraindicated in patients at high risk for arterial or venous thrombotic events, patients with a history of breast cancer or other estrogen/progesterone cancers, and patients with severe liver disease. Overall, the vaginal contraceptive ring is well tolerated and liked by patients. Patients should be well counseled on known severe adverse reactions. The vaginal contraceptive ring is more expensive than other forms of contraception and this should be an important point of discussion with patients.

Abstract
Worldwide, women face compounding reproductive health risks, including human immunodeficiency virus (HIV), sexually-transmitted infections (STIs), and unintended pregnancy. Multipurpose prevention technologies (MPTs) offer combined protection against these overlapping risks in singular prevention products that offer potential for simplified use, lower burden, higher acceptability, and increased public health benefits. Over the past decade, substantial progress has been made in development of extended-release MPTs, which have further potential to grant sexual and reproductive health autonomy to women globally and to offer choice for women to accommodate varying needs during their reproductive lives. Here, we highlight the advances made in injectable, implant, and ring delivery forms, and the importance of incorporating end-user preferences early in the research and development of these products.

Abstract
Intravaginal rings (IVRs) are minimally invasive polymeric devices specifically designed to be used for the sustained and prolonged release of various type of drugs such as hormones. One of the benefits of using topical drug delivery systems (e.g., IVRs) is the fact that systemic drug delivery may cause drug resistance due to elevated drug levels. Topical drug delivery also provides higher concentrations of the drug to the target site and has fewer side effects. In addition, when a drug is administered vaginally, the hepatic first-pass effect is avoided, resulting in higher absorption. Contraception and treatments for specific diseases such as endometriosis and hormone deficiencies can be improved by the administration of hormones via an IVR. This article aims to classify and compare various designs of commercially available and non-commercial hormonal IVRs and to analyze their performance. Current challenges affecting the development of IVRs are investigated, and
proposed solutions are discussed. A comprehensive search of publications in MEDLINE/PubMed and of commercial product data of IVRs was performed, and the materials, designs, performance, and applications (e.g., contraception, endometriosis, estrogen deficiency and urogenital atrophy) of hormonal IVRs were thoroughly evaluated. Most hormonal IVRs administer female sex hormones, i.e., estrogen and progestogens. In terms of material, IVRs are divided into 3 main groups: silicone, polyurethane, and polyethylene-co-vinyl acetate IVRs. As regards their design, there are 4 major designs for IVRs which strongly affect their performance and the timing and rate of hormone release. Important challenges include reducing the burst release and maintaining the bioavailability of hormones at their site of action over a prolonged period of administration as well as lowering production costs. Hormonal IVRs are a promising method which could be used to facilitate combination therapies by
administering multiple drugs in a single IVR while eliminating the side effects of conventional drug administration methods. IVRs could considerably improve womenʼs quality of life all over the world within a short period of time.

Abstract
PROBLEM Changes in sex hormones during the menstrual cycle and contraceptive vaginal ring (CVR) use influence immunity within the female genital tract, but the magnitude of these effects and their anatomical location are unclear. METHOD OF STUDY In a prospective study, 29 women were assessed at three-time points: follicular phase, luteal phase, and one month after initiation of the ethinyl estradiol/etonogestrel CVR (NuvaRing®, Merck). We performed microarrays on endocervical cytobrushes and measured immune mediators in cervicovaginal fluid, adjusting for bacterial vaginosis and the presence of blood. We compared these results to public gene expression data from the fallopian tubes, endometrium, endo- and ectocervix, and vagina. RESULTS Immune-related gene expression in the endocervix and immune mediators in cervicovaginal fluid increased during CVR use versus both menstrual phases, and in the follicular versus luteal phase. The antimicrobial protein granulysin was high during CVR use, intermediate in the follicular phase, and nearly absent from the luteal phase. Re-analysis of public gene expression data confirmed increased immune-related gene expression in the endocervix during the follicular phase. However, in the fallopian tube, endometrium, and vagina, the follicular phase showed immunosuppression. CONCLUSIONS Immune-related genes in the cervicovaginal tract were highest during CVR use, intermediate in the follicular phase, and lowest in the luteal phase. Granulysin is a potential biomarker of menstrual phase: Frequently detected in follicular samples, but rare in luteal. Lastly, immunological differences between the follicular and luteal phases vary throughout the female genital tract.

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
Hormones play a significant role in normal skin physiology and many dermatologic conditions. As contraceptives and hormonal therapies continue to advance and increase in popularity, it is important for dermatologists to understand their mechanisms and dermatologic effects given the intricate interplay between hormones and the skin. This article reviews the dermatologic effects, both adverse and beneficial, of combined oral contraceptives (COCs), hormonal intrauterine devices (IUDs), implants, injections, and vaginal rings. Overall, the literature suggests that progesterone-only methods, such as implants and hormonal IUDs, tend to trigger or worsen many conditions, including acne, hirsutism, alopecia, and even rosacea. Therefore, it is worthwhile to obtain detailed medication and contraceptive histories on patients with these conditions. There is sufficient evidence that hormonal contraceptives, particularly COCs and vaginal rings, may effectively treat acne and hirsutism. While there are less data to support the role of hormonal contraceptives in other dermatologic disorders, they demonstrate potential in improving androgenetic alopecia and hidradenitis suppurativa.

Abstract
While contraceptive drugs have enabled many people to decide when they want to have a baby, more than 100 million unintended pregnancies each year in the world may indicate the contraceptive requirement of many people has not been well addressed yet. The vagina is a well-established and practical route for the delivery of various pharmacological molecules, including contraceptives. This review aims to present an overview of different contraceptive methods focusing on the vaginal route of delivery for contraceptives, including current developments, discussing the potentials and limitations of the modern methods, designs, and how well each method performs for delivering the contraceptives and preventing pregnancy.

Abstract
The present state of reproductive and sexual health around the world reveals disparities in contraceptive use and effectiveness. Unintended pregnancy and sexually transmitted infection transmission rates remain high even with current prevention methods. The 20th century saw a contraceptive revolution with biomedical innovation driving the success of new contraceptive technologies with central design concepts and materials. Current modalities can be broadly categorized according to their mode of function: reversible methods such as physical/chemical barriers or hormonal delivery devices via systemic (transdermal and subcutaneous) or localized (intrauterine and intravaginal) administration, and nonreversible sterilization procedures such as tubal ligation and vasectomy. Contraceptive biomaterials are at present dominated by well-characterized elastomers such as polydimethylsiloxane and ethylene vinyl acetate due to their favorable material properties and versatility. Contraceptives alter the normal function of cellular components in the reproductive systems to impair fertility. The purpose of this review is to highlight the bioengineering design of existing methods, explore novel adaptations, and address notable shortcomings in current contraceptive technologies.

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.

Bleeding profile associated with 1-year use of the segesterone acetate/ethinyl estradiol contraceptive vaginal system: pooled analysis from Phase 3 trials. Contraception 2019; 100:438-444. [PMID: 31398307 PMCID: PMC6893119 DOI: 10.1016/j.contraception.2019.07.145] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 07/26/2019] [Accepted: 07/30/2019] [Indexed: 11/23/2022]
Abstract
OBJECTIVES To describe bleeding patterns among users of the segesterone acetate (SA) and ethinyl estradiol (EE) contraceptive vaginal system (CVS), and identify factors associated with unscheduled bleeding/spotting (B/S). STUDY DESIGN We pooled results from two multicenter, single-arm, open-label, pivotal, phase 3 studies of the SA/EE CVS conducted in 17 US and 7 international sites. Participants (age 18-40 years; BMI ≤29 kg/m2) followed a 21/7-day in/out schedule of CVS use for up to 13 cycles and recorded vaginal bleeding daily in paper diaries. Scheduled and unscheduled B/S were summarized by cycle. We used multiple logistic regression to identify factors associated with unscheduled bleeding/spotting, based on the first 4 cycles only. RESULTS Analysis included data from 2070 participants (16,408 cycles). Ninety-eight percent documented scheduled B/S [mean (SD): 4.9 (1.1) days/cycle)]. Absence of scheduled B/S was 5-8% of women/cycle. Unscheduled B/S ranged from 13.2% to 21.7% of women per cycle. Few women (1.8%) discontinued prematurely due to unacceptable bleeding. Black women were more likely to report unscheduled B/S than White women [Adjusted odds ratio (AOR) = 1.49, 95% confidence interval (CI) = 1.14-1.94]. Women with fewer years of schooling [ CONCLUSIONS Participants using the SA/EE CVS up to 13 cycles reported good cycle control. Discontinuation due to unacceptable bleeding was very low. Further research into demographic/other differences with reported unscheduled bleeding is warranted. IMPLICATIONS Since good cycle control is a key factor influencing contraceptive selection, adherence and continuation of combined hormonal contraceptives, the favorable bleeding profiles experienced by women during the SA/EE CVS clinical trials provide reassuring information for prospective users.

Abstract
CONTEXT Vaginal rings are available for contraception and hormone replacement, and are being developed as HIV/STD or multipurpose prevention technologies. A comprehensive understanding of women's expectations of and experiences with rings is urgently needed to inform product development and to optimize ring use. METHODS Three databases (PubMed, Global Health and CINAHL) were searched for English-language, peer-reviewed articles published between January 1996 and November 2017 that reported qualitative data on barriers to and facilitators of use of female-controlled contraceptive methods. Data on study methods, findings and conclusions pertaining to contraceptive rings were extracted, organized and analyzed. RESULTS Twenty-six articles, all published since 2008, met the inclusion criteria. Seven studies focused largely or entirely on rings (and involved current, former or potential users), while the others focused on other contraceptive methods but included ring-specific data. Familiarity with the ring was low, and women commonly had initial concerns about the method-often related to insertion and removal, cleanliness and discomfort with touching their vagina-that were typically overcome over time. Other major themes were issues related to ring use and discontinuation, the importance of ring-related properties and characteristics, and considerations related to sexual partners and health care providers. CONCLUSIONS Qualitative data have the potential to inform ring design and promotion. Future research should further explore women's expectations and experiences with the ring, the value of involving male partners in ring evaluation, and evaluation of interventions to improve patient-provider communication concerning ring choice and use.

Abstract
The development of topical inserts for the prevention of sexually transmitted infections (STIs), particularly human immunodeficiency virus (HIV), represents a promising alternative to oral and parenteral pre-exposure prophylaxis (PrEP) dosage forms. They may be used for vaginal and/or rectal administration of a variety of agents with antiviral activity. Topical inserts deliver drugs to the portal of viral entry, i.e., the genital or rectal mucosa, with low systemic exposure, and therefore are safer and have fewer side effects than systemic PrEP agents. They may dissolve fast, releasing the active drugs within minutes of insertion, or slowly for long-acting drug delivery. Furthermore, they are user-friendly being easy to administer, discreet and highly portable. They are also economical and easy to manufacture at scale and to distribute, with excellent stability and shelf-life. Altogether, topical inserts represent a particularly promising form of drug delivery for HIV and STI prevention. Highlighted within this review are end-user acceptability research dedicated to understanding preferred attributes for this form of drug delivery, advantages and disadvantages of the formulation platform options, considerations for their development, clinical assessment of select placebo prototypes, future directions, and the potential impact of this dosage form on the HIV prevention landscape.

Bone turnover markers in women participating in a dose-finding trial of a contraceptive vaginal ring releasing Nestorone and estradiol. Contraception 2019; 99:329-334. [PMID: 30871934 DOI: 10.1016/j.contraception.2019.02.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2018] [Revised: 02/01/2019] [Accepted: 02/18/2019] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To evaluate changes in the bone turnover markers CTx and P1NP during 6 months' use of novel continuous contraceptive vaginal rings delivering Nestorone (NES) 200 mcg/day and three doses of estradiol (E2) (10, 20, and 40 mcg/day). STUDY DESIGN This randomized trial enrolled 189 women who used two consecutive vaginal rings over 180 days. Frequent blood sampling permitted analysis of NES, E2, CTx and P1NP concentrations. The bone-turnover marker analyses included only women with complete sampling and excluded women with characteristics that might interfere with accurate measurement of bone markers such as afternoon sampling, poor ring compliance or recent pregnancy. We evaluated the change from baseline to 6 months in CTx and P1NP, stratified by ring dose and by average circulating E2 concentrations. RESULTS One hundred fifty-one women completed the study, and 82 women had complete data available for the bone marker analyses; the three dosage groups were balanced with regard to baseline characteristics. E2 concentrations remained low throughout treatment, regardless of which dose ring the participant used. Individual CTx changes from baseline averaged 27±56% (p<.01). Similarly, individual P1NP changes averaged 11±33% (p=.04). These increases were within the premenopausal reference ranges, and unrelated to treatment dose or to circulating E2 concentrations. CONCLUSIONS The low E2 dose of these rings was associated with low E2 concentrations and modest increases in serum bone turnover makers. Because we have only 6-month bone turnover markers and no direct evidence of bone loss or bone density change, these results must be interpreted with caution. IMPLICATIONS Nestorone, a 19-norprogesterone derivative, leads to complete ovarian suppression, which should yield excellent contraceptive effectiveness. To prevent potential adverse effects on bone, the NES contraceptive ring should be combined with higher doses of E2 than were assessed in this study.

Abstract
Background Given future potential use of vaginal rings to prevent HIV infection, we examined the association of contraceptive vaginal ring (CVR) non-adherence with user dissatisfaction, tolerability, demographic, and behavioral factors. Methods In an open-label single-group study, sexually active women aged 18-34 years using oral or injectable hormonal contraception, conveniently sampled from general population, were assigned to 6-month use of a commercial CVR currently not licensed for use in Kenya. Non-adherence in any CVR cycle completed was assessed from: (1) self-report (not used for at least 1 day), and (2) pharmacy record (failure to timely receive a new CVR or return a used one). Additionally, non-adherence was assessed in a subset of participants by residual progestin and estrogen levels measured in returned CVRs. Results Of 202 participants who underwent CVR insertion by a study clinician, 142 completed all 6 visits, 172 responded to questions about ring use, and 43 provided used CVRs from months 1, 3, and 6 for residual hormone analysis. Non-adherence was 14.0% (24/172) by self-report and 54.5% (110/202) by pharmacy record. Non-adherence by pharmacy record was significantly reduced among women with a salary-based income (prevalence ratio (PR) 0.71, 95% confidence interval (CI) (0.55-0.91)] compared to women with income not salary-based or no income. Participants dissatisfied with CVR on ≥4 aspects (ambiguity of instructions, inconvenience of use, sensation, sexual discomfort, etc.) were more likely to report non-adherence (PR 2.69, 95% CI=(1.31-5.52)] compared to those dissatisfied with ≤3 aspects. Non-adherence by residual hormone levels was identified in 46.5% (20/43) participants. Over time, this subset of participants showed increasing non-adherence (P=0.004). We found lack of agreement among the various measures of non-adherence. Conclusions Economic empowerment interventions, especially those emphasizing partner-independent income options, and expanded education on CVR features may alleviate non-adherence. Addressing CVR dissatisfaction preemptively may also help mitigate non-adherence.

Abstract
The link between melanoma development and the use of oral combined contraceptives is not fully elucidated, and the data concerning this issue are scarce and controversial. In the present study, we show that the components of oral contraceptives, ethinylestradiol (EE), levonorgestrel (LNG), and their combination (EE + LNG) ± UVB (ultraviolet B radiation) induced differential effects on healthy (human keratinocytes, fibroblasts, and primary epidermal melanocytes, and murine epidermis cells) and melanoma cells (human—A375 and murine—B164A5), as follows: (i) at low doses (1 µM), the hormones were devoid of significant toxicity on healthy cells, but in melanoma cells, they triggered cell death via apoptosis; (ii) higher doses (10 µM) were associated with cytotoxicity in all cells, the most affected being the melanoma cells; (iii) UVB irradiation proved to be toxic for all types of cells; (iv) UVB irradiation + hormonal stimulation led to a synergistic cytotoxicity in the case of human melanoma cells—A375 and improved viability rates of healthy and B164A5 cells. A weak irritant potential exerted by EE and EE + LNG (10 µM) was assessed by the means of a chick chorioallantoic membrane assay. Further studies are required to elucidate the hormones’ cell type-dependent antimelanoma effect and the role played by melanin in this context.

Abstract
BACKGROUND Introduction of contraceptive vaginal rings (CVRs) could expand the contraceptive method mix reducing the unmet need for family planning in Rwanda, but data on acceptability of CVRs from low and middle-income countries are lacking. METHODS This study explores acceptability of contraceptive vaginal ring (NuvaRing) use in Kigali, Rwanda using a mixed methods approach. We collected quantitative and qualitative data before, during and after conducting a clinical trial, using Case Report Forms, Interviewer Administered Questionnaires, In Depth Interviews and Focus Group Discussions. We analyzed the data using an existing theoretical framework including product attributes, relationship attributes and sexual encounter attributes as well as the contextual environment. RESULTS Our data showed that initial worries reduced over time with actual ring use and ring insertions and removals were described as easy. Most women did not feel the ring during daily activities, appreciated the lack of perceived negative side effects and the increased lubrication. Relationship attributes and sexual encounter attributes such as sexual comfort played a significant role in ring acceptability of the participants and their partners. The contextual environment including Rwandan cultural norms around sexuality positively influenced the acceptance of the NuvaRing. Overall satisfaction was high. CONCLUSIONS Acceptability of the Nuvaring was high among study participants and represents a promising option that could contribute to lowering the unmet need for family planning in Rwanda.

Abstract
OBJECTIVE To show the clinical development of Ornibel® (ExeltisHealthcare, Spain) a contraceptive vaginal ring manufactured with a new polymer composition and containing etonogestrel/ethinylestradiol, compared to Nuvaring® (MSD, Spain). SUBJECTS AND METHODS Randomised, single dose, 2-period, 2-sequence, 2-stage crossover, comparative bioavailability study conducted in 40 healthy female subjects. All subjects received both treatments for 28 days in each of two periods, separated by a 28 days washout. Ornibel® contains etonogestrel/ethinylestradiol 11.00/3.47 mg and Nuvaring® contains etonogestrel/ethinylestradiol 11.7/2.7 mg, both rings delivering 120/15 µg/day. For the calculation of pharmacokinetic parameters, 37 blood samples were collected up to 840 h after each ring insertion to quantify plasma concentrations of etonogestrel and ethinylestradiol using a validated MS/MS-HPLC. Safety was assessed by adverse events recording, clinical laboratory and vital signs and tolerability by vaginal examination. Acceptability was investigated by a 5-point scale questionnaire. RESULTS Bioequivalence was demonstrated in the first stage as the 94.12% Confidence Intervals of the primary parameters laid within the 80-125% acceptance range for both etonogestrel (Cmax: 96.81-112.20%; AUC0-504h: 98.71-108.61%; AUC0-t: 100.14-109.10%) and ethinylestradiol. (Cmax: 105.91-120.62%; AUC0-504h: 105.47-114.59%; AUC0-t: 108.31-117.61%). During the first day of use a burst effect was observed with Nuvaring®, with significantly higher level of ethinylestradiol (Cmax0-24h ratio: 78.34%, 94.12CI: 73.55-83.45%). Both products were well tolerated and accepted, without significant differences between them. CONCLUSION Ornibel® is bioequivalent to Nuvaring® in terms of efficacy, safety, tolerability and acceptability. The new polymer composition provides Ornibel® with more stability and gradual hormonal release during the first day of use, particularly for ethinylestradiol.

Abstract
Introduction Intramuscular and vaginal progesterone are recommended for prevention of preterm labor (PTL) in women with risk factors. Studies are emerging to indicate that HIV-infected women on combination antiretroviral therapy (cART) are at risk of PTL and low birth weight (LBW), and may benefit from supplemental progesterone. This study aims to determine the perceived acceptability of various modes of progesterone supplementation to prevent PTL and LBW in HIV-infected and HIV-uninfected women. Methods HIV-infected and HIV-uninfected women were recruited in Lusaka, Zambia. The participants completed a questionnaire to assess their willingness to take oral, vaginal, or intramuscular progesterone supplementation for preventing PTL and LBW, preferred modes of supplementation, and concern for PTL and LBW. Results The study questionnaire was completed by 147 participants. Of the participants, 98.6% would consider using a medication to help prevent PTL and LBW, of whom 97.9% would consider using an oral form of progesterone. In addition, 83.3% and 84.0% of women would consider intramuscular and vaginal (gel or tablet) administration of progesterone respectively. Between intramuscular and vaginal modes of progesterone, 60.5% of participants (n=147) preferred intramuscular progesterone, while 39.5% preferred vaginal progesterone. There was no difference in preference between HIV-infected (n=70) and HIV-uninfected (n=77) women. Conclusions/implications Pregnant Zambian women demonstrated a high degree of acceptance for all modes of progesterone supplementation for the prevention of PTL and LBW. Women preferred intramuscular over vaginal supplementation. Progesterone supplementation can be considered a feasible intervention for preventing PTL and LBW in both HIV-infected and HIV-uninfected pregnant Zambian women.

Abstract
STUDY OBJECTIVE To explore adolescent's perceptions of vaginal health, practices, and vaginally-placed products. DESIGN Semistructured interviews were audio-recorded and transcribed until theoretical saturation was achieved. SETTING Adolescent medicine clinics in New York City. PARTICIPANTS Female adolescents (N = 22) who were sexually experienced, predominately Hispanic (73%, n = 16) with a mean age of 17.7 years (range, 15-20 years). INTERVENTIONS None. MAIN OUTCOME MEASURES Interviews were used to assess perspectives on vaginal health, specific vaginal hygiene practices, and attitudes about vaginally-placed products (contraceptive rings, intrauterine devices), and proposed multipurpose technologies administered as ring or gel). The interviews were transcribed and coded for relevant themes. RESULTS Overlapping themes included young women's view of their vagina as a space that needed to be healthy for sexual partners and future fertility. The vagina could not be presumed to be healthy and conversations about vaginal health were limited to include only specific individuals. All reported a variety of practices to maintain their vaginal health, including showering 1-5 times a day and using soaps specifically for the vagina. Attitudes about vaginally-placed products revealed concerns about the sensory experience of having a product in the vagina, safety concerns and interest in the product's objective (prevention of pregnancy or infection). CONCLUSION Adolescents have very specific views and practices about their vaginas. Clinicians should initiate conversations about vaginal health and hygiene with adolescents and focus on the normalcy of the vagina. Development of vaginally-placed products should focus on the sensory experience, safety, and purpose of the product.

Abstract
INTRODUCTION We assessed performance and safety of the NuvaRing® Applicator. METHODS We randomized women (18-45 years) to insert a placebo ring using the applicator or fingers-only and then vice versa. We assessed outcomes post-insertion and then 24-72 h later. RESULTS Insertion was 100% successful using both methods (applicator, n=163; fingers-only, n=162). A total of 8.6% (applicator) and 4.3% (fingers-only) of subjects reported at least 1 treatment-related adverse event (AE); all were mild. Subjects reported 5 applicator-related AEs (vulvovaginal pain, 4; abdominal cramping, 1). There was no vaginal bleeding within 15 h post-applicator use. Ring expulsions were rare (applicator, 1; fingers-only, 2). CONCLUSION NuvaRing Applicator is effective and well-tolerated (NCT02275546).

Abstract
UNLABELLED trans-Epithelial delivery of medication across the vagina has proven successful for administration of small, lipophilic molecules such as sex steroids. However, little information is available regarding the vaginal delivery of larger and more polar molecules that currently require parenteral administration because the vaginal epithelium is perceived as a barrier to absorption of larger molecular weight (MW) molecules. Six healthy women underwent administration of 18 or 36mg of leuprolide, a GnRH agonist and a larger MW peptide, via a novel ethylene vinyl acetate (EVA) ring transvaginal drug delivery system (TVDS). Serum levels rose within 8h following insertion: low dose at 310pg/ml and high dose at 1220pg/ml, i.e. levels typically following parenteral injections of leuprolide. GnRHa biological activity was validated by secretion of gonadotropins and sex steroids. These results demonstrate that the non-keratinized vaginal epithelium permits a rapid absorption of a biologically active peptide and that there is significant potential for a novel TVDS to deliver peptides and possibly other macromolecules therapeutically. SIGNIFICANCE STATEMENT Current routes of administration of medications can include oral, subcutaneous, intravenous, intramuscular, transcutaneous, etc. Many of these approaches have limitations, including pain, poor tolerability, lack of adherence, and inadequate delivery. Peptides, in particular, cannot typically be given orally because they are broken down in the intestinal tract before they are absorbed. While the skin is an attractive way to deliver medications, its superb intrinsic barrier function often makes this route untenable at times. The vaginal epithelium, in contrast, is not keratinized and can allow absorption of other molecules. In this study, we demonstrate that a novel transvaginal drug delivery system (TVDS) is capable of delivering peptide therapeutics to women in a non-parenteral fashion as demonstrated by both blood levels and biologic effects of its delivery.

Abstract
Intravaginal rings (IVRs) are currently under investigation as devices for the delivery of agents to protect against the sexual transmission of HIV and STIs, as well as pregnancy. To assist product developers in creating highly acceptable rings, we sought to identify characteristics that intravaginal ring users consider when making decisions about ring use or non-use. We conducted four semi-structured focus groups with 21 women (aged 18-45) who reported using an IVR in the past 12 months. Participants manipulated four prototype rings in their hands, discussed ring materials, dimensionality, and "behavior," and shared perceptions and appraisals. Five salient ring characteristics were identified: 1) appearance of the rings' surfaces, 2) tactile sensations of the cylinder material, 3) materials properties, 4) diameter of the cylinder, and 5) ring circumference. Pliability (or flexibility) was generally considered the most important mechanical property. Several ring properties (e.g., porousness, dimensionality) were associated with perceptions of efficacy. Women also revealed user behaviors that may impact the effectiveness of certain drugs, such as removing, rinsing and re-inserting the ring while bathing, and removing the ring during sexual encounters. As product developers explore IVRs as prevention delivery systems, it is critical to balance product materials and dimensions with use parameters to optimize drug delivery and the user experience. It is also critical to consider how user behaviors (e.g., removing the ring) might impact drug delivery.

Abstract
UNLABELLED Nuvaring (Organon, Kenilworth, NJ) is a vaginal contraception ring inserted by the patient. It was approved by the Food and Drug Administration in 2001 for the prevention of pregnancy. The intent of this paper is to increase the awareness of Nuvaring among plastic surgeons, and to explore the risks associated with its use. We report the cases of two cosmetic surgery patients. These patients developed deep venous thrombosis and pulmonary emboli in the postoperative period while using Nuvaring. The very advantages of the Nuvaring-the ease of use, the avoidance of daily administration, and the insertion and removal of the device by the patient-may lead to the failure of patients to recollect being on a vaginal ring for contraception. LEVEL OF EVIDENCE 4 Risk.

Abstract
The aim of this study was to compare combined hormonal vaginal ring with ultralow-dose combined oral contraceptive (COC) pills in management of heavy menstrual bleeding (HMB). Fifty patients were randomised into Group I: vaginal ring (n = 25) and group II: COC pills (n = 25). Menstrual blood loss (MBL) was assessed at baseline, 1, 3 and 6 months (while on treatment) and at 9 months (3 months after stopping therapy). There was significant reduction in baseline pictorial blood loss assessment chart (PBAC) score from 440 ± 188 (Mean ± SD) to 178 ± 95, 139 ± 117, 112 ± 84 and 120 ± 108 in group I and from 452 ± 206 to 204 ± 152, 179 ± 125, 176 ± 164 and 202 ± 167 in group II at 1, 3, 6 and 9 months, respectively (p = 0.001). Reduction in MBL was 72% and 62% at 6 months and up to 71% and 55% at 9 months in group I and group II, respectively (p = 0.001). Reduction in MBL with ring was greater at higher baseline PBAC score but lesser in patients with fibroid > 2 cm. Combined vaginal hormonal treatment for HMB is as effective as oral hormonal therapy, with minor and transient side effects and persistence of response after cessation of therapy.

Abstract
The NuvaRing® is a deformable, ring-shaped hormonal contraceptive device which is typically vaginally self-inserted by the patient. While there are several potential side effects of usage, essentially all of them result from hormone delivery. Complications from incorrect placement are rare. We present the case of a 31 year old female who presented to our emergency department after being unable to retrieve a NuvaRing® for its scheduled removal. CT scan showed a hypodense intravesicular NuvaRing® which the patient had inadvertently placed transurethrally 3 weeks prior. Cystoscopy was performed and retrieval using a 3-pronged grasper was eventually successful after several failed attempts with an alligator grasper. Our purpose in presenting this case is to introduce the reader to a rare complication of incorrect NuvaRing® placement, explain how this complication may occur as a result of NuvaRing® construction/functionality, describe how alternative cystoscopic instruments may aid in cystoscopic retrieval, and review the 3 other case reports of intravesicular NuvaRing® placement to discuss the utility of various imaging modalities when clinical suspicion of the complication is high.

Abstract
OBJECTIVE To evaluate the quality of the sexual life of healthy women who are using a contraceptive vaginal ring (CVR) in extended cycles. METHODS Fifty-two women (18 to 32 years old) seeking hormonal contraception were enrolled in this prospective study. Women were to use a CVR releasing daily 15 μg of ethinylestradiol (EE) and 120 μg of etonogestrel (ENG) for 63 days, followed by a four-day hormone-free interval, for two such extended cycles. At baseline and at the first (day 63-73) and second (day 126-134) follow-ups the Female Sexual Function Index (FSFI) and the Short Form-36 (SF-36) questionnaires were administered to investigate, respectively, sexual behaviour and the quality of life (QoL). The Female Sexual Distress Scale (FSDS) was used to verify whether sexual dysfunction caused significant personal distress to the woman. RESULTS The FSFI and FSDS scores obtained at the first and second follow-up appointments detected an improvement with respect to the baseline score (p < 0.05). QoL measures of body pain, general health and emotional role improved at the first follow-up visit (p < 0.05); at the second one, all variables showed improvement (p < 0.05). CONCLUSION According to these preliminary data the CVR in extended cycles could improve the sexual function and the QoL of women.

Abstract
BACKGROUND Healthcare providers (HCPs) have an important role in helping women select the contraceptive method that best matches their needs and lifestyle. Recent surveys outline the need of women to be informed about all available choices, including the newest methods (particularly those not requiring daily administration), such as vaginal contraception. METHODS The most relevant publications on combined contraceptive vaginal ring are revised in the context of counseling as an opportunity to empower women in term of vaginal health and sexual functioning. RESULTS HCPs should explain the main characteristics of the combined contraceptive vaginal ring including the anatomical and physiological implications that make the vagina an ideal route of hormonal administration and the basic notions about functional modifications of the vagina during reproductive life. Clinical data on the vaginal ring should be summarized with regard to efficacy, tolerability, pharmacokinetics, cycle control and user acceptability, including recent findings on extra-contraceptive benefits (also compared to other hormonal contraceptives) on the vaginal flora and on sexual function. CONCLUSION Vaginal contraception offers various benefits and should always be discussed during contraceptive counseling. An open dialogue about vaginal contraception will also help enhance body knowledge and sexual health.

Abstract
BACKGROUND To provide an overview of the available data from clinical studies of vaginal conditions in women who use a vaginal ring as a contraceptive. METHODS A systematic review of the literature. RESULTS Millions of women have already used the ethylene vinyl acetate vaginal ring that releases ethinylestradiol and etonogestrel for contraception. Because of its small size, more than four out of five women using the ring report that they do not feel it, even during sexual intercourse. No colposcopic or cytological changes have been observed in users, although approximately 10% have increased vaginal discharge. While in vitro studies have shown adhesion of Candida yeasts to the vaginal ring surface, clinical studies have not demonstrated a greater incidence of Candida infections compared to users of equivalent oral contraceptives. Some clinical studies suggest a lower incidence of bacterial vaginosis. No interaction exists between concomitant use of the vaginal ring and other drugs or products for vaginal use. CONCLUSION The use of a contraceptive vaginal ring does not alter the vaginal ecosystem and therefore does not substantially affect vaginal health.

Abstract
A vaginal gel containing the antiretroviral tenofovir (TFV) recently demonstrated 39% protection against HIV infection in women. We designed and evaluated a novel reservoir TFV intravaginal ring (IVR) to potentially improve product effectiveness by providing a more controlled and sustained vaginal dose to maintain cervicovaginal concentrations. Polyurethane tubing of various hydrophilicities was filled with a high-density TFV/glycerol/water semisolid paste and then end-sealed to create IVRs. In vitro, TFV release increased with polyurethane hydrophilicity, with 35 weight percent water-swelling polyurethane IVRs achieving an approximately 10-mg/day release for 90 days with mechanical stiffness similar to that of the commercially available NuvaRing. This design was evaluated in two 90-day in vivo sheep studies for TFV pharmacokinetics and safety. Overall, TFV vaginal tissue, vaginal fluid, and plasma levels were relatively time independent over the 90-day duration at approximately 10(4) ng/g, 10(6) ng/g, and 10(1) ng/ml, respectively, near or exceeding the highest observed concentrations in a TFV 1% gel control group. TFV vaginal fluid concentrations were approximately 1,000-fold greater than levels shown to provide significant protection in women using the TFV 1% gel. There were no toxicological findings following placebo and TFV IVR treatment for 28 or 90 days, although slight to moderate increases in inflammatory infiltrates in the vaginal epithelia were observed in these animals compared to naïve animals. In summary, the controlled release of TFV from this reservoir IVR provided elevated sheep vaginal concentrations for 90 days to merit its further evaluation as an HIV prophylactic.

Abstract
BACKGROUND The sector of the market that deals with contraception offers a long list of different contraceptive methods. Within the estroprogestinic choice, the routes of administration are oral, transdermic and vaginal one. Even though efficacy is comparable with these methods, secondary and adverse effects are directly involved in the acceptability of the method. STUDY DESIGN This was a prospective comparative study. During 1 year, we enrolled 60 asymptomatic women who voluntarily requested combined oral contraception (COC) or combined contraceptive vaginal ring (CCVR group). After a baseline study of vaginal milieu prior to starting hormonal contraception, we performed a follow-up. For each woman, we examined vaginal pH; quantification of leukocytes, lactobacilli, Candida and cocci on saline microscopy fluid; Gram stain with Nugent score and the presence of vaginal infection [culture for Trichomonas vaginalis, albicans and nonalbicans Candida, Group B Streptococcus (GBS)]. RESULTS At the end of follow-up, there was a little change of vaginal milieu in both groups. We noted an increase of lactobacilli in the CCVR users and an increase of GBS in COC users. CONCLUSION CCVR compared to COC users showed an increase of the number of lactobacilli in vaginal flora. It means that an increase of leukorrhea in that group could be protective in terms of prevention of vaginal imbalance/infection.

Abstract
INTRODUCTION The development of multiple indication (multipurpose) prevention technologies (MIPTs) is driven by overlapping relationships in the area of female reproductive health. AREAS COVERED In this review, the basis for MIPTs is detailed. The current state of the field for the use of drug delivery in novel MIPTs is covered. Of particular interest is the application of intravaginal rings (IVRs) for the delivery of two drugs simultaneously, to prevent one STI and pregnancy, or two STIs. IVRs are currently available commercially for contraception and have been developed for release of microbicides to prevent sexual transmission of HIV-1. Novel IVRs capable of releasing relatively large amounts of drugs such as tenofovir are discussed, along with those that contain independent delivery elements, such as pods, that can be used to release drugs at independent rates. The vaginal administration of macromolecules (antibodies and vaccines) is also reviewed in the context of MIPTs. EXPERT OPINION The field of MIPTs remains one of potential. There is yet to be a proven microbicide effective at preventing sexual transmission of HIV-1. Development of MIPTs in the near term will proceed under the assumption that one or more antiretroviral (ARV) drugs will eventually be proven successful. IVRs have already demonstrated success in the area of contraception. Prevention of sexual transmission of HIV-1 and herpes simplex virus-2 (HSV-2) (or suppression of recurrence) remains an attractive MIPT target. In the long term, development of MIPTs will require validation of surrogate end points, particularly for prevention of HIV-1 transmission.
