Abstract
BACKGROUND Adults with developmental disabilities often have less access to reproductive health services than adults without these disabilities. However, little is known about how adolescents with developmental disabilities, including autism, access reproductive healthcare. OBJECTIVE We aimed to characterize the use of reproductive healthcare services among adolescents with autism and those with other developmental disabilities in comparison with adolescents with typical development. STUDY DESIGN We conducted a cohort study of a sample of adolescents who were continuously enrolled members of Kaiser Permanente Northern California, an integrated healthcare system, from ages 14 to 18 years. The final analytical sample included 700 adolescents with autism, 836 adolescents with other developmental disabilities, and 2187 typically developing adolescents who sought care between 2000 and 2017. Using the electronic health record, we obtained information on menstrual conditions, the use of obstetrical-gynecologic care, and prescriptions of hormonal contraception. We compared healthcare use between the groups using chi-square tests and covariate-adjusted risk ratios estimated using modified Poisson regression. RESULTS Adolescents with autism and those with other developmental disabilities were significantly more likely to have diagnoses of menstrual disorders, polycystic ovary syndrome, and premenstrual syndrome than typically developing adolescents. These 2 groups also were less likely than typically developing peers to visit the obstetrician-gynecologist or to use any form of hormonal contraception, including oral contraception, hormonal implants, and intrauterine devices. Adolescents in all 3 groups accessed hormonal contraception most frequently through their primary care provider, followed by an obstetrician-gynecologist. CONCLUSION Adolescents with autism and those with other developmental disabilities are less likely than their typically developing peers to visit the obstetrician-gynecologist and to use hormonal contraception, suggesting possible care disparities that may persist into adulthood. Efforts to improve access to reproductive healthcare in these populations should target care delivered in both the pediatric and obstetrics-gynecology settings.

Contraceptive Recommendations for Women with Immune-Mediated Inflammatory Diseases: A Delphi Consensus. Adv Ther 2024; 41:1372-1384.

Abstract
INTRODUCTION Immune-mediated inflammatory diseases (IMID) are a group of disorders characterized by chronic inflammation caused by an altered immune regulation in targeted organs or systems. IMID itself could have an implied increased risk of venous thromboembolism (VTE) and this risk varies throughout the course of the disease as well as with some contraceptive methods and treatments. The aim of this study was to present some key considerations in relation to contraception in women with IMID. METHODS This was an exploratory study conducted in Spain following the online modified Delphi methodology with two rounds of participation. Four questionnaires were designed for each medical specialty: gastroenterology, rheumatology, dermatology, and gynecology. Each questionnaire was divided in three domains: general recommendations about IMID, specific recommendations, and contraceptive methods for patients with IMID. A 5-point Likert scale measured agreement with each statement, with an 80% agreement threshold. Following the first round, the percentage of each response was calculated for every item. Subsequently, a second round was conducted to reach a consensus on the items for which discrepancies were observed. RESULTS A total of 52 and 50 experts participated in the first and second round, respectively. Participants agreed on the existence of a higher risk of VTE in inflammatory bowel diseases, psoriasis, and rheumatoid arthritis diseases. Regarding recommendations for contraceptive methods in patients with IMID, experts considered the hormonal intrauterine device (IUD) as a first-line contraceptive (80.0%) and low doses of progesterone-only pills if the latter is not recommended (88.0%). Most of the interviewees concurred on the importance of the patients' contraceptive needs during the disease course (98.1%). CONCLUSION Raising awareness and promoting a multidisciplinary relationship among the physicians involved in the therapeutic decisions by considering all the risk factors when prescribing a contraceptive method is important to prevent VTE in women with IMID.

Abstract
Microneedle (MN)-assisted drug delivery technology has gained increasing attention over the past two decades. Its advantages of self-management and being minimally invasive could allow this technology to be an alternative to hypodermic needles. MNs can penetrate the stratum corneum and deliver active ingredients to the body through the dermal tissue in a controlled and sustained release. Long-acting polymeric MNs can reduce administration frequency to improve patient compliance and therapeutic outcomes, especially in the management of chronic diseases. In addition, long-acting MNs could avoid gastrointestinal reactions and reduce side effects, which has potential value for clinical application. In this paper, advances in design strategies and applications of long-acting polymeric MNs are reviewed. We also discuss the challenges in scale manufacture and regulations of polymeric MN systems. These two aspects will accelerate the effective clinical translation of MN products.

Mijatovic V, Vercellini P. Towards comprehensive management of symptomatic endometriosis: beyond the dichotomy of medical versus surgical treatment. Hum Reprod 2024; 39:464-477. [PMID: 38199787 DOI: 10.1093/humrep/dead262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 12/06/2023] [Indexed: 01/12/2024] Open
Abstract
Except when surgery is the only option because of organ damage, the presence of suspicious lesions, or the desire to conceive, women with endometriosis-associated pain often face a choice between medical and surgical treatment. In theory, the description of the potential benefits and potential harms of the two alternatives should be standardized, unbiased, and based on strong evidence, enabling the patient to make an informed decision. However, doctor's opinion, intellectual competing interests, local availability of specific services and (mis)information obtained from social media, and online support groups can influence the type of advice given and affect patients' choices. This is compounded by the paucity of robust data from randomized controlled trials, and the anxiety of distressed women who are eager to do anything to alleviate their disabling symptoms. Vulnerable patients are more likely to accept the suggestions of their healthcare provider, which can lead to unbalanced and physician-centred decisions, whether in favour of either medical or surgical treatment. In general, treatments should be symptom-orientated rather than lesion-orientated. Medical and surgical modalities appear to be similarly effective in reducing pain symptoms, with medications generally more successful for severe dysmenorrhoea and surgery more successful for severe deep dyspareunia caused by fibrotic lesions infiltrating the posterior compartment. Oestrogen-progestogen combinations and progestogen monotherapies are generally safe and well tolerated, provided there are no major contraindications. About three-quarters of patients with superficial peritoneal and ovarian endometriosis and two-thirds of those with infiltrating fibrotic lesions are ultimately satisfied with their medical treatment although the remainder may experience side effects, which may result in non-compliance. Surgery for superficial and ovarian endometriosis is usually safe. When fibrotic infiltrating lesions are present, morbidity varies greatly depending on the skill of the individual surgeon, the need for advanced procedures, such as bowel resection and ureteral reimplantation, and the availability of expert colorectal surgeons and urologists working together in a multidisciplinary approach. The generalizability of published results is adequate for medical treatment but very limited for surgery. Moreover, on the one hand, hormonal drugs induce disease remission but do not cure endometriosis, and symptom relapse is expected when the drugs are discontinued; on the other hand, the same drugs should be used after lesion excision, which also does not cure endometriosis, to prevent an overall cumulative symptom and lesion recurrence rate of 10% per postoperative year. Therefore, the real choice may not be between medical treatment and surgery, but between medical treatment alone and surgery plus postoperative medical treatment. The experience of pain in women with endometriosis is a complex phenomenon that is not exclusively based on nociception, although the role of peripheral and central sensitization is not fully understood. In addition, trauma, and especially sexual trauma, and pelvic floor disorders can cause or contribute to symptoms in many individuals with chronic pelvic pain, and healthcare providers should never take for granted that diagnosed or suspected endometriosis is always the real, or the sole, origin of the referred complaints. Alternative treatment modalities are available that can help address most of the additional causes contributing to symptoms. Pain management in women with endometriosis may be more than a choice between medical and surgical treatment and may require comprehensive care by a multidisciplinary team including psychologists, sexologists, physiotherapists, dieticians, and pain therapists. An often missing factor in successful treatment is empathy on the part of healthcare providers. Being heard and understood, receiving simple and clear explanations and honest communication about uncertainties, being invited to share medical decisions after receiving detailed and impartial information, and being reassured that a team member will be available should a major problem arise, can greatly increase trust in doctors and transform a lonely and frustrating experience into a guided and supported journey, during which coping with this chronic disease is gradually learned and eventually accepted. Within this broader scenario, patient-centred medicine is the priority, and whether or when to resort to surgery or choose the medical option remains the prerogative of each individual woman.

Part II: medical interventions. Hum Reprod 2024; 39:18-34.

Abstract
According to consistent epidemiological data, the slope of the incidence curve of endometriosis rises rapidly and sharply around the age of 25 years. The delay in diagnosis is generally reported to be between 5 and 8 years in adult women, but it appears to be over 10 years in adolescents. If this is true, the actual onset of endometriosis in many young women would be chronologically placed in the early postmenarchal years. Ovulation and menstruation are inflammatory events that, when occurring repeatedly for years, may theoretically favour the early development of endometriosis and adenomyosis. Moreover, repeated acute dysmenorrhoea episodes after menarche may not only be an indicator of ensuing endometriosis or adenomyosis, but may also promote the transition from acute to chronic pelvic pain through central sensitization mechanisms, as well as the onset of chronic overlapping pain conditions. Therefore, secondary prevention aimed at reducing suffering, limiting lesion progression, and preserving future reproductive potential should be focused on the age group that could benefit most from the intervention, i.e. severely symptomatic adolescents. Early-onset endometriosis and adenomyosis should be promptly suspected even when physical and ultrasound findings are negative, and long-term ovulatory suppression may be established until conception seeking. As nowadays this could mean using hormonal therapies for several years, drug safety evaluation is crucial. In adolescents without recognized major contraindications to oestrogens, the use of very low-dose combined oral contraceptives is associated with a marginal increase in the individual absolute risk of thromboembolic events. Oral contraceptives containing oestradiol instead of ethinyl oestradiol may further limit such risk. Oral, subcutaneous, and intramuscular progestogens do not increase the thromboembolic risk, but may interfere with attainment of peak bone mass in young women. Levonorgestrel-releasing intra-uterine devices may be a safe alternative for adolescents, as amenorrhoea is frequently induced without suppression of the ovarian activity. With regard to oncological risk, the net effect of long-term oestrogen-progestogen combinations use is a small reduction in overall cancer risk. Whether surgery should be considered the first-line approach in young women with chronic pelvic pain symptoms seems questionable. Especially when large endometriomas or infiltrating lesions are not detected at pelvic imaging, laparoscopy should be reserved to adolescents who refuse hormonal treatments or in whom first-line medications are not effective, not tolerated, or contraindicated. Diagnostic and therapeutic algorithms, including self-reported outcome measures, for young individuals with a clinical suspicion of early-onset endometriosis or adenomyosis are proposed.

Abstract
BACKGROUND Primary dysmenorrhea (PD) is a common gynecological condition causing depression. Acupuncture is an effective option for PD management but its effects on PD-associated depression remain unclear. METHODS A retrospective cohort study involving 35,099 propensity score-matched pairs of acupuncture users and non-users with PD was conducted using data from Taiwan's Longitudinal Generation Tracking Database 2000. Cox proportional hazard models were used to estimate depression risk, and bioinformatics analyses were performed to uncover underlying molecular mechanisms. RESULTS The risk of developing depression was reduced by 64 % in acupuncture users compared with non-acupuncture users during the 19-year follow-up period. The decrease was dose-dependent. Bioinformatics analyses identified 34 co-expressed targets for acupuncture, PD, and depression; and eight hub genes (coding for interleukin 6 and 1B, tumor necrosis factor, albumin, vascular endothelial growth factor A, C-reactive protein, prostaglandin-endoperoxide synthase 2, and brain-derived neurotrophic factor) potentially involved in the therapeutic effects of acupuncture. Several molecular pathways were found to be involved, including cytokine-cytokine receptor interaction, neuroactive ligand-receptor interaction, cyclic adenosine 3',5'-monophosphate signaling pathway, mitogen-activated protein kinase signaling pathway, serotonergic synapse, and estrogen signaling pathway. LIMITATIONS Bias in the selection of participants could have been introduced as a consequence of the retrospective nature of the study. Data were derived from a single national database, and acupuncture treatment details were unavailable. CONCLUSION Acupuncture may protect against the development of depression in patients with PD. This study provides insight into the potential molecular mechanisms underlying the therapeutic effects of acupuncture in PD management and depression prevention.

Abstract
17α-estradiol has recently been shown to extend healthspan and lifespan in male mice through multiple mechanisms. These benefits occur in the absence of significant feminization or deleterious effects on reproductive function, which makes 17α-estradiol a candidate for translation into humans. However, human dosing paradigms for the treatment of aging and chronic disease are yet to be established. Therefore, the goals of the current studies were to assess tolerability of 17α-estradiol treatment, in addition to evaluating metabolic and endocrine responses in male rhesus macaque monkeys during a relatively short treatment period. We found that our dosing regimens (0.30 and 0.20 mg/kg/day) were tolerable as evidenced by a lack of GI distress, changes in blood chemistry or complete blood counts, and unaffected vital signs. We also found that the higher dose did elicit mild benefits on metabolic parameters including body mass, adiposity, and glycosylated hemoglobin. However, both of our 17α-estradiol trial doses elicited significant feminization to include testicular atrophy, increased circulating estrogens, and suppressed circulating androgens and gonadotropins. We suspect that the observed level of feminization results from a saturation of the endogenous conjugation enzymes, thereby promoting a greater concentration of unconjugated 17α-estradiol in serum, which has more biological activity. We also surmise that the elevated level of unconjugated 17α-estradiol was subjected to a greater degree of isomerization to 17β-estradiol, which is aligned with the sevenfold increase in serum 17β-estradiol in 17α-estradiol treated animals in our first trial. Future studies in monkeys, and certainly humans, would likely benefit from the development and implementation of 17α-estradiol transdermal patches, which are commonly prescribed in humans and would circumvent potential issues with bolus dosing effects.

Abstract
PURPOSE Adolescent pregnancy, while recently in decline, remains a matter in need of addressing. Education and counselling are deemed crucial and this review aims at comparing published contraceptive guidelines, thus resolving any surrounding misconceptions. MATERIALS AND METHODS Recently published contraception guidelines regarding adolescent pregnancy were retrieved. In particular, guidelines and recommendations from ACOG, RCOG, SOCG, AAP, CPS, NICE, CDC, and WHO were compared and reviewed based on each guideline's method of reporting. RESULTS Three categories of contraceptive methods are available for adolescents and recommendations on their initiation should be made based on their efficacy, according to all guidelines. Therefore, long acting reversible contraceptives (LARCs) should be highly recommended as the most effective method (typical use failure rate: 0.05%), followed by short-acting hormonal contraceptives (typical use failure rate: 3-9%). The third contraceptive option includes contraceptives used in the moment of intercourse and displays the lowest effectiveness (typical use failure rate: 12-25%), mostly due to its dependence on personal consistency, however offers protection against STI transmission. CONCLUSION Adolescents should be encouraged to initiate contraception, with LARCs being the primary choice followed by short-acting hormonal contraception. However, regardless of the chosen effective contraceptive method, the use of condom is necessary for STI prevention.

Abstract
There is a tremendous need for simple-to-administer, long-acting contraception, which can increase access to improved family planning. Microneedle (MN) patches enable simple self-administration and have previously been formulated for 1-2 months' controlled release of contraceptive hormone using monolithic polymer/drug MN designs having first-order release kinetics. To achieve zero-order release, we developed a novel core-shell MN patch where the shell acts as a rate-controlling membrane to delay release of a contraceptive hormone, levonorgestrel (LNG), for 6 months. In this approach, LNG was encapsulated in a poly(lactide-co-glycolide) (PLGA) core surrounded by a poly(l-lactide) (PLLA) shell and a poly(D,l-lactide) (PLA) cap that were fabricated by sequential casting into a MN mold. Upon application to skin, the core-shell MNs utilized an effervescent interface to separate from the patch backing within 1 min. The core-shell design limited the initial 24 h burst release of LNG to 5.8 ± 0.5% and achieved roughly zero-order LNG release for 6.2 ± 0.1 months in vitro. A monolithic MN patch formulated with the same LNG and PLGA core, but without the rate-controlling PLLA shell and PLA cap had a larger LNG burst release of 22.6 ± 2.0% and achieved LNG release for just 2.1 ± 0.2 months. This study provides the first core-shell MN patch for controlled months-long drug release and supports the development of long-acting contraception using a simple-to-administer, twice-per-year MN patch.

Palmeira-de-Oliveira R, Oliveira AS, Rolo J, Tomás M, Palmeira-de-Oliveira A, Simões S, Martinez-de-Oliveira J. Women's preferences and acceptance for different drug delivery routes and products. Adv Drug Deliv Rev 2022; 182:114133. [PMID: 35104506 DOI: 10.1016/j.addr.2022.114133] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Revised: 01/22/2022] [Accepted: 01/26/2022] [Indexed: 12/14/2022]
Abstract
To use or not to use, that is the first decision to take regarding a drug product. This mandatory step for adherence dictates product efficacy. The determinants for such decision do not only rely on the priority of the therapeutic or preventive strategy, but are related to a complex network of perceptions, preferences, personal and cultural backgrounds, and results from previous experiences. Women's preferences for dosage forms and even for drug delivery routes have been mainly studied in the fields of contraception and HIV prevention (and their related multipurpose approaches). Much less attention has been devoted to other therapeutic or preventive strategies. In a time when patient-centred approaches and shared decisions are increasingly valued, considering women's preferences and their main determinants is essential for product development and selection. Such products will be more likely to be chosen and used as intended, increasing efficacy, and reducing the overall costs related with these treatments. This knowledge shall be integrated in early stages of product development. This article reviews the state of the art related with women's preferences and acceptance for different dosage forms and drug delivery routes involved in women's health. The methodologies used for collecting these data and their major drawbacks are discussed. Results obtained from acceptability studies and the main determinants for selection of preventive and treatment drug products are discussed as tools for new developments in the field.

Randomized, double-blind, two-way crossover bioequivalence and adhesion study, in healthy women, of a transdermal contraceptive patch with a newly sourced adhesive component at the end of shelf life vs. the EVRA patch at the beginning of shelf life. Int J Clin Pharmacol Ther 2022; 60:67-78.

Abstract
OBJECTIVE Evaluate bioequivalence, based on norelgestromin (NGMN) and ethinyl estradiol (EE) plasma concentrations, and adhesion of a transdermal contraceptive patch containing a newly sourced adhesive component (test) at end of shelf life (EOSL) vs. the marketed EVRA patch (reference) at beginning of shelf life (BOSL). MATERIALS AND METHODS In this randomized, double-blind, two-way crossover study, healthy women received a single, 7-day application of test and reference patches in 4 sequences: two 11-day treatment periods separated by a 21-day washout. Assessments included NGMN and EE pharmacokinetics (PK), adhesion (per European Medicines Agency (EMA) 5-point scale), irritation potential and application-site reactions, and tolerability. Patches were bioequivalent if 90% CIs of geometric mean ratios (GMRs) of test/reference for Cmax, AUC168h, AUC0-tlast, and AUC∞ were 80 - 125%. Patch adhesion was comparable if ratios of geometric mean cumulative adhesion percentages were ≥ 90%. RESULTS 68 women were randomized, and 62 completed both treatments. 55 and 59 participants in the reference and test group, respectively, had patch adhesion ≥ 80% (EMA score 0 - 1) at end of treatment. Bioequivalence was demonstrated: GMRs for pharmacokinetic (PK) parameters ranged from 102.76 - 105.57% for NGMN and 93.78 - 94.80% for EE, and associated 90% CIs were fully within the bioequivalence acceptance range (80 - 125%) for both. The patches had comparable adhesion properties (GMR, 101.4% (90% CI: 99.2 - 103.6)) and incidences of treatment-emergent adverse events. CONCLUSION NGMN-EE transdermal test patch at EOSL was bioequivalent to the marketed patch at BOSL, supporting widening the product's shelf-life specification. Adhesive properties and safety profiles were comparable between patches.

Abstract
Suppression of menstruation and/or ovarian function in adolescent girls may be desired for a variety of reasons. Numerous medical options exist. The choice of the appropriate modality for an individual patient depends on several factors based on differences in the efficacy of achieving menstrual suppression as well as in their side effect profiles. Adolescence is also a period of bone mass accrual in girls, and several of these modalities may negatively influence peak bone mass. This review focuses on the efficacy of achieving menstrual suppression and the effect on bone health of the various options through an overview of the current literature and also highlights areas in need of further research.

Abstract
Heavy, and often irregular, menstrual bleeding (HMB) is a common gynecologic complaint among adolescents. During the first few post-menarcheal years, anovulatory cycles related to immaturity of the hypothalamic-pituitary-ovarian axis are the most common etiology for abnormal uterine bleeding and should be considered as a part of normal pubertal development rather than a disease. If an already regular menstrual cycle becomes irregular, secondary causes of anovulation should be ruled out. Inherited and acquired bleeding disorders, such as von Willebrand disease, and quantitative and qualitative abnormalities of platelets are relatively common findings in adolescents with HMB from menarche. History of excessive bleeding or a diagnosed bleeding disorder in the family supports this etiology, warranting specialized laboratory testing. First-line treatment of HMB among adolescents is medical management with hormonal therapy or nonhormonal options. Levonorgestrel-releasing intrauterine device is an effective tool also for all adolescents with menstrual needs.

Abstract
Adolescents are at risk for unwanted pregnancy when they become sexually active, and contraception is an important part of mitigating this risk. Use of contraceptive methods, and long-acting reversible contraceptive methods such as implants and intrauterine devices in particular, has increased among adolescents. Although sexual activity has declined and contraceptive use has increased among adolescents in the United States in recent years, the unintended pregnancy rate remains high. All of the currently available contraceptive methods are safe and effective for adolescents to use; however, adolescents may have specific concerns about side effect profiles and unscheduled bleeding that should be addressed during contraceptive counseling. Healthcare providers should prioritize adolescents' needs and preferences when approaching contraceptive counseling, and also consider the unique access and confidentiality issues that adolescents face when accessing contraception.

Abstract
Medical devices and medicinal products have many similarities in their nature, scope or specific medical purposes, and despite the differences in their principal means of action, they are often used in combination. Indeed, many medicinal products depend on medical devices for their administration, and it is increasingly common for medical devices to contain medicinal substances to support their action. Therefore, the combination of medicinal products and medical devices provides additional benefits for patients. However, their higher technical complexity requires a strengthening of their authorisation and certification requirements. In this regard, more comprehensive requirements and classification rules are introduced by a new European regulation on medical devices that fully applies from May 26th 2021. On account of their therapeutic significance, this review aims at gaining insight into the borderline between medical devices and medicinal products in this new 2021 regulatory framework. For the first time, any item containing a medical device and a medicinal product will have both parts evaluated. Through exemplification of both marketed and investigational devices incorporating medicinal substances and drug-device combinations, the new European requirements and their implications are thoroughly illustrated herein.

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
INTRODUCTION In this paper, we report general pharmacological profile and major biological activities of natural progesterone (P) and progestins. The aim of this article consists of synthesizing the principal aspects of pharmacology and metabolism of P and progestins related to the clinical consequences of their use. METHODS We review scientific literature on the topic "Progestins", evaluating the most relevant data from original articles, reviews and meta-analyses. EVIDENCE SYNTHESIS Progestins represent a specific class of synthetic analogues of P clinically employed (alone or associated with estrogens) to manage several gynaecological conditions, for instance multiple abortions, luteal phase defect, premenstrual syndrome, abnormal uterine bleeding, endometriosis and menopause (for hormone replacement therapy). Besides their use in the field of contraception, many non-contraceptive benefits of estroprogestins are mostly due to the activities of progestins. Pharmacological characteristics, dosage and individual metabolism could be listed among the principal aspects influencing their clinical effects. CONCLUSIONS The choice of each progestin according to its pharmacological profile is crucial for the appropriate management of any gynaecological condition. An aware knowledge of these compounds is fundamental to hone medical practice.

Abstract
Despite the existence of a variety of contraceptive products for women, as well as decades of research into the prevention and treatment of human immunodeficiency virus (HIV), there is still a globally unmet need for easily accessible, acceptable, and affordable products to protect women's sexual and reproductive health. Microarray patches (MAPs) are a novel platform being developed for the delivery of hormonal contraception and antiretroviral drugs. MAPs provide enhanced drug delivery to the systemic circulation via the transdermal route when compared to transdermal patches, oral and injectable formulations. These minimally invasive patches can be self-administered by the user, reducing the burden on health care personnel. Since MAPs represent needle-free drug delivery, no sharps waste is generated after application, thereby eliminating possible MAP reuse and risk of needle-stick injuries. This review discusses the administration of contraceptive and antiretroviral drugs using MAPs, their acceptability by end-users, and the future perspective of the field.

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
Contraception is widely used in the United States, and nurses in all settings may encounter patients who are using or want to use contraceptives. Nurses may be called on to anticipate how family planning intersects with other health care services and provide patients with information based on the most current evidence. This article describes key characteristics of nonpermanent contraceptive methods, including mechanism of action, correct use, failure rates with perfect and typical use, contraindications, benefits, side effects, discontinuation procedures, and innovations in the field. We also discuss how contraceptive care is related to nursing ethics and health inequities.

Abstract
Over two-thirds of women will experience breast pain in their lifetime. As one of the leading breast symptoms for which women seek medical attention, breast pain is suspected to be underreported and under-studied. Cyclical breast pain is related to hormonal changes. Noncyclical breast pain is independent of the menstrual cycle and can be idiopathic and related to chronic pain syndromes, infections, ill-fitting bras, musculoskeletal abnormalities, pregnancy, perimenopause, and postsurgical causes. Breast pain can also present in transgender patients and may require additional considerations as to the underlying cause. Imaging of mastalgia depends upon the suspected etiology. Inappropriate imaging for breast pain is associated with significant utilization of health care resources. Cyclical breast pain does not require an imaging work-up. The work-up of focal, noncyclical breast pain includes ultrasound for women aged younger than 40 years, and mammography and ultrasound for women aged 40 years and older. Management of breast pain is often supportive, as most breast pain resolves spontaneously. If pain persists, imaging and management should follow a step-wise approach. If conservative measures fail, second-line therapy is topical nonsteroidal anti-inflammatory drugs. If breast pain is severe and resistant to conservative methods, additional third-line therapies can be added by breast care specialists with specific knowledge of the potential deleterious side effects of these medications. While the causes of mastalgia are overwhelmingly benign, breast pain can significantly impact quality of life, and the breast radiologist should be familiar with causes, management, and treatment recommendations from a multidisciplinary approach.

Abstract
OBJECTIVE To develop an evidence-based guideline on contraception, assisted reproductive technologies (ART), fertility preservation with gonadotoxic therapy, use of menopausal hormone replacement therapy (HRT), pregnancy assessment and management, and medication use in patients with rheumatic and musculoskeletal disease (RMD). METHODS We conducted a systematic review of evidence relating to contraception, ART, fertility preservation, HRT, pregnancy and lactation, and medication use in RMD populations, using Grading of Recommendations Assessment, Development and Evaluation methodology to rate the quality of evidence and a group consensus process to determine final recommendations and grade their strength (conditional or strong). Good practice statements were agreed upon when indirect evidence was sufficiently compelling that a formal vote was unnecessary. RESULTS This American College of Rheumatology guideline provides 12 ungraded good practice statements and 131 graded recommendations for reproductive health care in RMD patients. These recommendations are intended to guide care for all patients with RMD, except where indicated as being specific for patients with systemic lupus erythematosus, those positive for antiphospholipid antibody, and/or those positive for anti-Ro/SSA and/or anti-La/SSB antibodies. Recommendations and good practice statements support several guiding principles: use of safe and effective contraception to prevent unplanned pregnancy, pre-pregnancy counseling to encourage conception during periods of disease quiescence and while receiving pregnancy-compatible medications, and ongoing physician-patient discussion with obstetrics/gynecology collaboration for all reproductive health issues, given the overall low level of available evidence that relates specifically to RMD. CONCLUSION This guideline provides evidence-based recommendations developed and reviewed by panels of experts and RMD patients. Many recommendations are conditional, reflecting a lack of data or low-level data. We intend that this guideline be used to inform a shared decision-making process between patients and their physicians on issues related to reproductive health that incorporates patients' values, preferences, and comorbidities.

Comparison of a transdermal contraceptive patch with a newly sourced adhesive component versus EVRA patch: A double-blind, randomized, bioequivalence and adhesion study in healthy women. Contraception 2020; 101:276-282. [PMID: 31935382 DOI: 10.1016/j.contraception.2019.12.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Revised: 12/09/2019] [Accepted: 12/11/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To evaluate the bioequivalence of norelgestromin and ethinyl estradiol (NGMN-EE) and adhesion of a transdermal contraceptive patch containing a newly sourced adhesive component (test) compared with the marketed (reference) patch. STUDY DESIGN In this randomized, double-blind, 2-way crossover study, healthy women received single 7-day application of both test and reference patches. Treatment phase included two treatment periods of 11 days each separated by a 21-day washout period starting from day of patch removal (day 8) of treatment period 1. Assessments included NGMN and EE pharmacokinetics (PK), adhesion using European Medicines Agency (EMA) 5-point scale, irritation potential and application-site reactions, and safety. Patches were bioequivalent if 90% CIs of ratios of means of test/reference for AUC168h, AUCinf, and Css fell within 80-125%. Patch adhesion was comparable if ratios of mean cumulative adhesion percentage values of test/reference were ≥90.0%. RESULTS Seventy women were randomized; 57 completed both treatments with ≥80% adhesion (score 0-1). Bioequivalence of test and reference patches was demonstrated as 90% CI of ratio of geometric means for AUC168h, AUCinf, and Css for NGMN and EE fell within 80-125%. Both patches had similar adhesion properties (geometric mean ratio was 100.3% [90% CI, 93.2-107.9]). Similar rates of mild-to-moderate itching (11% vs 10%) and erythema events (79% vs 74%) were reported for test and reference patches, respectively, on day 8. CONCLUSIONS The test patch with the newly sourced adhesive component is bioequivalent to the currently marketed NGMN-EE transdermal patch and has similar adhesion and irritation potential. IMPLICATIONS STATEMENT The norelgestromin and ethinyl estradiol transdermal patch containing a newly sourced adhesive component is bioequivalent to the currently marketed patch for both active moieties. Both patches had similar adhesion, irritation potential, and safety profiles.

Abstract
Family planning represents a key component of reproductive health care. Accordingly, the provision of contraception must span the reproductive age spectrum, including perimenopause. The risk of pregnancy is decreased, but not trivial, among women over 40 years of age. Evidence-based guidelines for contraceptive use can assist clinicians in counseling their patients in this population. Intrauterine contraception is one of the most effective methods and is safe to use in midlife women with few exceptions. Progestin-only contraception is another safe option for most midlife women because it is not associated with an increased risk of cardiovascular complications. Combined (estrogen-containing) contraception can be safely used by midlife women who do not have cardiovascular risk factors. Unique noncontraceptive benefits for this population include: improvement in abnormal uterine bleeding, decreased hot flashes, and decreased cancer risk. Finally, guidelines state that contraception can be used by midlife women without medical contraindications until the age of menopause, at which time they may consider transition to systemic hormone therapy.

Abstract
Menstrual suppression (the use of hormonal contraceptive methods to eliminate or significantly decrease the frequency of menstrual cycles) is frequently used in the adolescent population for the management of menstrual symptoms such as heavy or painful periods, premenstrual syndrome, menstrual migraines, or even for patient preference. However, in cases of menstrual suppression in special populations additional risks and benefits need to be considered. The purpose of this article is to review the options and medical considerations for menstrual suppression in patients undergoing chemotherapy who might be at risk of abnormal uterine bleeding, those with intellectual or physical disability, and transgender and gender nonbinary individuals.

Abstract
OBJECTIVES To evaluate safety outcomes from clinical studies of a 12-month contraceptive vaginal system (CVS) releasing an average of segesterone acetate (SA) 150 mcg and ethinyl estradiol (EE) 13 mcg daily. STUDY DESIGN We integrated clinical safety data from nine studies in which women used the CVS for 21 consecutive days and removed it for 7 days of each 28-day cycle. Four studies used the final manufactured CVS, including a 1-year pharmacokinetic study, two 1-year phase 3 trials and a second-year treatment extension study. We assessed safety by evaluating adverse events women reported in a daily diary. We also included data from focused safety studies evaluating endometrial biopsies, vaginal microbiology and liver proteins from one of the phase 3 studies. RESULTS The combined studies included 3052 women; 2308 women [mean age 26.7±5.1 years; mean body mass index (BMI) 24.1±3.7 kg/m2] received the final manufactured CVS, of whom 999 (43.3%) completed 13 cycles of use. Women using the final CVS most commonly reported adverse events of headache (n=601, 26%), nausea (n=420, 18%), vaginal discharge/vulvovaginal mycotic infection (n=242, 10%) and abdominal pain (n=225, 10%). Few (<1.5%) women discontinued for these complaints. Four (0.2%) women experienced venous thromboembolism (VTE), three of whom had risk factors for thrombosis [Factor V Leiden mutation (n=1); BMI>29 kg/m2 (n=2)]. During 21,482 treatment cycles in the phase 3 studies evaluable for expulsion, women reported partial expulsions in 4259 (19.5%) cycles and complete expulsions in 1509 (7%) cycles, most frequently in the initial cycle [499/2050 (24.3%) and 190/2050 (9.3%), respectively]. Safety-focused studies revealed no safety concerns. CONCLUSION The 1-year SA/EE CVS has an acceptable safety profile. Additional studies are warranted in obese women at higher risk of VTE. IMPLICATIONS This 1-year contraceptive vaginal system represents a new long-term, user-controlled and procedure-free option with a safety profile similar to other combination hormonal contraceptives. The same precautions currently used for combination hormonal contraceptive prescriptions apply to this new contraceptive vaginal system.

Abstract
Long acting reversible contraception (LARC) is the recommend form of birth control for adolescents by both the American Academy of Pediatrics and the American Congress of Obstetrics and Gynecology, but the majority of adolescents continue to use short acting reversible contraception (SARC) such as the oral contraceptive pill, vaginal ring, and transdermal patch. For this reason, it is important for medical providers to be familiar with how to prescribe and manage SARC in adolescents, paying particular attention to which patients are eligible to use them, which benefits the methods have outside of contraception, what side effects to be aware of, and special considerations for adolescents. Many adolescents will choose not to use any form of hormonal contraception-thus having a knowledge about and comfort with use of emergency contraception is of equal importance.
