ENVIRONMENTAL RESEARCH 2024; 259:119498. [PMID: 38942254 DOI: 10.1016/j.envres.2024.119498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 06/07/2024] [Accepted: 06/24/2024] [Indexed: 06/30/2024]
Abstract
Microplastics (MPs) can enter the reproductive system and can be potentially harmful to human reproductive health. In this study, 13 types of microplastics (MPs) were identified in patient blood, cancer samples, and paracarcinoma samples using Raman spectroscopy, with polyethylene, polypropylene and polyethylene-co-polypropylene being the most abundant polymer types. Futher, cotton was also found in our study. The diversity and abundance of MPs were higher in blood samples than in cancerous tissues, and there was a significant positive correlation between diversity (p < 0.05). Furthermore, the diversity and abundance of MPs in cancerous tissues were higher than in paracancerous tissues. The dimensional sizes of MPs in these samples were also very similar, with the majority of detected MPs being smaller in size. Correlation analysis showed that patient's age correlated with the abundance of MPs in blood samples, body mass index (BMI) correlated with the abundance of MPs in cancerous tissues. Notably, the frequency with which patients consume bottled water and beverages may also increase the abundance of MPs. This study identifies for the first time the presence of MPs and cotton in cancerous and paracancerous tissues of human cervical cancer patients. This provides new ideas and basic data to study the risk relationship between MP exposure and human health.

Abstract
With the increase in the world's population, contraception is crucial in population control strategies. Majority of contraceptives produced today are targeted at women; many of whom experience side effects, leading to the discontinuation of these contraceptives after a year of use. As the use of condoms and vasectomies has been subjected to scrutiny, it is necessary for the development of male birth control (BC). Attempts to achieve this include hormonal and non-hormonal contraception. Hormonal contraception prevents the production of the sperm in the testes; but this mode of BC has been found to be ineffective while also causing behavioural changes in men. In contrast, non-hormonal male contraception focuses on rendering the sperm immotile to prevent fertilization post-copulation. Soluble adenylate cyclase is an area of research that has shown promise in this field. Furthermore, two inhibitors, TDI-10299 and TDI-11861, have been developed and tested, with the latter, showing greater potency and longer activity, in mice models. Overall, by developing non-hormonal male contraceptives, men will have more control over their reproductive health. Nonetheless, before such contraceptives can be made widely available, it is important that further research takes place to ensure the safety and effectiveness of these methods.

Abstract
BACKGROUND This study aimed to elucidate the scope and nature of adverse events (AEs) associated with Yasmin. METHODS Among the 17,035,572 AE reports collected from the Food and Drug Administration Adverse Event Reporting System (FAERS) database between January 2004 and September 2023, 25,949 reports involved Yasmin. The demographic details, clinical outcomes, and sources of reports were extracted, and four algorithms were used to evaluate adverse drug reactions. RESULTS The majority of the AE reports involved females aged 18-45 years. Hospitalization was the most frequently reported serious outcome (46.84 %), with death occurring in 292 patients (1.82 %). The highest number of reports originated from the United States. Adverse reactions spanned across 24 system organ categories (SOCs), and hepatobiliary, vascular, and psychiatric disorders were the most frequently reported AEs. A total of 229 Preferred Terms (PTs) were identified for adverse reactions, with high signal strength observed for conditions such as post-cholecystectomy syndrome. In addition, fear of disease, which has not been previously identified as an AE related to Yasmin, was also identified as a high signal strength side effect. CONCLUSION The findings of the present study underscore the importance of monitoring and identifying potential AEs in patients receiving Yasmin, including those not currently listed in the medication instructions.

Abstract
BACKGROUND Breastfeeding is a process for not only nourishing infants but also for building a unique emotional bond between mother and child. Therefore, the ideal contraception during lactation should not affect lactation (milk composition, milk volume) and offspring development. OBJECTIVES This study aims to analyze the literature on the safety of progestogen hormonal contraceptive methods during lactation. METHODS We conducted a thorough search across various databases, including the National Library of Medicine (PubMed), and the Cochrane Database, Drugs and Lactation Database (LactMed). Our search utilized specific phrases such as: "lactation" and "breastfeeding" and "oral contraception" with "drospirenone" or "desogestrel", with "subcutaneous etonogestrel implant" or "etonogestrel implant", with "levonorgestrel-releasing intrauterine system", and "emergency contraception", with "levonorgestrel" or "ulipristal acetate". CONCLUSIONS Based on published scientific reports, progestogen hormonal contraceptives can be considered a relatively safe solution for women desiring to continue feeding their infant with their milk while using hormonal contraception. It is important to seek guidance on selecting the best contraception method based on the latest medical knowledge, tailored to the individual needs and clinical circumstances of each woman and place of residence. A woman should always be informed of the potential risks of such a treatment and then allowed to make her own decision based on the knowledge received from a specialist.

Abstract
INTRODUCTION Utilization of modern contraceptives increases over time but it was still low and varies across ages among married youth woman. This study revealed the prevalence of modern contraceptives and its associated factors among younger and older married youth women. METHODS A cross-sectional study design was applied to the sample of EMDHS 2019. Multilevel logistic regressions were carried out using STATA version 16 to identify the individual and community-level factors of modern contraceptive utilization. Adjusted odds ratios with a 95% confidence interval and variables with a p-value < 0.05 were considered to be significant determinants of modern contraceptive utilization. RESULT In the EMDHS 2019, a total of 3290 married women between ages 15 and 34 were included. Among these 1210 (36.7%) and 2080 (63%) women, they were age groups of 15-24 and 25-34 years, respectively. Modern contraceptive utilization among women aged 15-24 and 25-34 years was 54.23% and 52.6%, respectively. Injection is a commonly used modern contraceptive method. In this study, factors associated with modern contraceptive utilization among women aged 15-24 years include women who had primary education [AOR = 2.22; 95% CI: 1.02-4.83], who had three or more children in the household [AOR = 14.29; 95% CI: 1.61-126.25], Protestants [AOR = 0.29; 95% CI: 0.14-0.61], five to seven households [AOR = 0.34; 95% CI: 0.17-0.69], and region [AOR = 6.98; 95%:2.30-21.16]. On other hand, factors associated with modern contraceptive utilization among women aged 25-34 were women who had one or two under-five children in the household [AOR = 1.66; 95% CI: 1.03-2.68] and region [AOR = 3.54; 95%CI: 1.79-6.97]. CONCLUSIONS More than 50% of participants used modern contraceptives in both age groups and, the associated factor of modern contraceptive utilization varied among this age group. Health managers and policymakers need to consider age group, region, educational status, religion, and fertility level in planning of family planning program.

Mohammed A, Donkoh IE, Aboagye RG, Ahinkorah BO, Seidu AA. Access to quality contraceptive counselling among adolescent girls and young women in sub-Saharan Africa. Contracept Reprod Med 2024; 9:16. [PMID: 38622719 PMCID: PMC11017582 DOI: 10.1186/s40834-024-00267-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Accepted: 01/27/2024] [Indexed: 04/17/2024] Open
Abstract
BACKGROUND Improving women's access to and use of modern contraceptives is a key global strategy for improving the sexual and reproductive health of women. However, the use of modern contraceptives among adolescent girls and young women in sub-Saharan Africa (SSA) remains relatively low, despite the numerous interventions to increase patronage. This study examined adolescent girls and young women's receipt of quality contraceptive counselling and its associated factors in SSA. METHODS Data for the study were extracted from the recent Demographic and Health Surveys of 20 countries in SSA, spanning from 2015 to 2021. A sample of 19,398 adolescent girls and young women aged 15 to 24 years was included in the study. We presented the proportion of adolescent girls and young women who received quality contraceptive counselling using a spatial map. Multilevel binary logistic regression analysis was carried out to examine the factors associated with the receipt of quality contraceptive counselling. RESULTS Overall, 33.2% of adolescent girls and young women had access to quality contraceptive counselling, ranging from 13.0% in Cameroon to 67.0% in Sierra Leone. The odds of receiving quality contraceptive counselling was higher among adolescent girls and young women aged 20-24 (AOR = 1.48, CI: 1.32-1.67), those with primary (AOR = 1.32, CI: 1.11-1.57) and secondary or higher education (AOR = 1.31, CI: 1.09-1.58), and those married (AOR = 1.32, CI: 1.15-1.52), cohabiting (AOR = 1.47, CI: 1.23-1.76), and previously married (AOR = 1.48, CI: 1.20-1.83) compared to their counterparts in the reference groups. Adolescent girls and young women who were currently working (AOR = 1.22, CI: 1.09-1.37), those who heard of family planning from radio in the last few months (AOR = 1.34, CI:1.21-1.50), those who visited the health facility in the last 12 months (AOR = 1.69, CI: 1.52-1.88), and those residing in the Southern (AOR = 5.01, CI: 3.86-6.51), Eastern (AOR = 2.54, CI: 1.96-3.30), and Western (AOR = 4.09, CI: 3.19-5.25) SSA were more likely to receive quality contraceptive counselling compared to their counterparts in the reference groups. Conversely, adolescent girls and young women who used the internet, those who had problem getting permission to seek medical help, those facing problem in seeking medical help for not wanting to go alone, those from the middle and richest wealth indices, and those from the rural areas were less likely to receive quality contraceptive counselling compared to their counterparts in the reference groups. CONCLUSION Receipt of quality contraceptive counselling among adolescent girls and young women was low. Considering the importance of quality contraceptive counselling on the uptake and continuation of contraception, policymakers need to institute measures that improve adolescent girls and young women's access to quality contraceptive counselling in SSA, especially in countries like Cameroon, Angola, Madagascar, Mauritania, and Guinea, taking into consideration the factors identified in the study. Increasing adolescent girls and young women's access to quality contraceptive counselling could greatly minimize the risk of unintended pregnancies and its associated maternal and child health burden in SSA and subsequently contribute to the attainment of the Sustainable Development Goal 3, target 3.7.

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

Abstract
The pollution of microplastics (MPs) has received widespread attention with the increasing usage of plastics in recent years. MPs could enter the human body and exist in the circulatory system. Endometrium, with rich blood vessels, acts as an essential role in human health and female fertility. However, there is no study reporting the MPs exposure in human endometrium. We collected the endometrium samples to detect the presence of MPs qualitatively and quantitatively via laser direct infrared. We found that there was a total of 13 types of MPs existing in the collected samples, among which 6 special types of MPs were with both high abundance and high detection rate. The abundance of these MPs ranged from 0 to 117 particles/100 mg, with a median abundance of 21 particles/100 mg. Most detected MPs, accounting for 88.35 %, were in small size (20-100 μm). Among small-size MPs, ethylene-acrylic acid copolymer ranked first while polyethylene accounted for the largest proportion among large-size MPs (100-500 μm). Correlation analysis indicated there was no significant relationship between age and MP abundance or BMI and MP abundance. We also designed a questionnaire to investigate lifestyle and daily habits, aiming at revealing the potential relationship between MP exposure and living habits. We discovered that some drinking habits and chewing gum were significantly correlated with a higher level of MP exposure. For the first time, we identified the presence of MPs in human endometrium and clarified the potential connections between MP exposure and lifestyle. Further studies are still necessary to explore more underlying information.

Abstract
Women with systemic lupus erythematosus (SLE) who get pregnant while SLE is active or while on teratogens have higher risk of poor pregnancy outcomes. The American College of Rheumatology (ACR) Reproductive Health Guidelines recommend women conceive when SLE is well controlled and treated with pregnancy-compatible medications. The Healthy Outcomes in Pregnancy with SLE Through Education of Providers (HOP-STEP) Intervention was created to ascertain pregnancy interest and contraceptive use followed by a personalized pregnancy prevention and/or planning discussion (https://www.LupusPregnancy.org). All study participants were adult females enrolled in a prospective registry who met ACR or SLICC criteria. Women were defined as "not medically ready for pregnancy" if they were currently prescribed a teratogen, had proteinuria ≥500 mg, or had elevated SLE activity according to the physician's global assessment. Two time periods were assessed: 2/2018-12/2019 and 10/2020-4/2021 to evaluate pre- and post-pandemic periods, with some post-pandemic visits taking place via telehealth. The interest in pregnancy was similar between the first time period (17%) and the second time period, whether in-person (18%) or virtual (18%). Pregnancy interest was assessed significantly more frequently during in-person visits (90%) compared to virtual encounters (67%) (p = .02). Contraceptive use was not significantly different during either time period with use of a teratogen or increased SLE activity. Of the 52 women in both time periods who were not medically ready for pregnancy and were not on effective contraception, three women (5.8%) conceived. None of the women who were using moderate or highly effective contraception became pregnant. Pregnancy outcomes were similar between unintended or high-risk and well-timed pregnancies. The HOP-STEP Intervention effectively identified pregnancy interest, giving rheumatologists the opportunity to address patient reproductive goals, optimize disease activity, and adjust medication regimens prior to conception.

Abstract
Objective: To investigate unintended pregnancy and changes in mood, acne, and weight in NOMAC-E2 vs levonorgestrel-containing COC (COCLNG) users under 25 years.Methods: In this large, observational study, new users (first-ever users of an eligible COC or restarting with the same or a new eligible COC after a break of at least 2 months) of NOMAC-E2 and COCLNG were recruited in 12 countries in Europe, Australia, and Latin America and followed up via questionnaires for up to 2 years. Unintended pregnancy was expressed by the Pearl Index (PI; contraceptive failures/100 women-years). Crude (HRcrude) and adjusted hazard ratios (HRadj) were calculated. Mood and acne changes were defined as change of score from baseline. Weight change was defined as percent change of body weight.Results: Overall, 12,829 NOMAC-E2 users and 17,095 COCLNG users under 25 were followed-up. The risk of unintended pregnancy was statistically significantly lower in the NOMAC-E2 cohort; confirmed events: 30 NOMAC-E2 (PI 0.24; 95% CI, 0.16-0.35) vs 94 COCLNG (PI 0.51; 95% CI, 0.41-0.62). The HRcrude for unintended pregnancy comparing NOMAC-E2 to COCLNG was 0.47 (95% CI, 0.31-0.71) and the HRadj was 0.52 (95% CI, 0.34-0.78). No differential effect on acne, mood, and weight was observed between cohorts.Conclusions: NOMAC-E2 shows a significantly better contraceptive effectiveness in young women and has no differential effect on acne, mood, and weight compared to COCLNG.

Abstract
HIV/AIDS and maternal mortality are the two leading causes of death among women of reproductive age in sub-Saharan Africa. A growing body of research investigates opportunities for multipurpose prevention technologies (MPTs) that prevent unintended pregnancy, HIV, and/or other sexually transmitted infections (STIs) with a single product. More than two dozen MPTs are currently in development, most of them combining contraception with HIV pre-exposure prophylaxis, with or without protection from other STIs. If successful, such MPTs could offer women benefits at multiple levels: greater motivation for effective use; lower product administration burden; accelerated integration of HIV, STI, and reproductive health services; and opportunities to circumvent stigma by using contraception as a "fig leaf" for HIV and/or STI prevention. However, even if women find respite from product burden, lack of motivation, and/or stigma in contraceptive-containing MPTs, their use of MPTs will be interrupted, often multiple times, over the reproductive lifecourse due to desire for pregnancy, pregnancy and breastfeeding, menopause, and changes in risk. Interruptions to the benefits of MPTs could be avoided by combining HIV/STI prevention with other life-stage-appropriate reproductive health products. New product concepts could include combining prenatal supplements with HIV and STI prevention, emergency contraception with HIV post-exposure prophylaxis, or hormone replacement therapies for menopause with HIV and STI prevention. Research is needed to optimize the MPT pipeline based on the populations underserved by available options and the capacity of resource-constrained health systems to deliver novel preventative healthcare products.

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
In the 2022 PAPPS update we present those specific preventive activities for women's health, except those related to cancer prevention (which are included in another document) and those aspects related to differential gender morbidity, a cross-cutting aspect for all working groups. Contraception is an essential preventive activity, considering basic the right to decide both the number of children and the time to have them. We must inform about the possible contraceptive methods, guaranteeing the monitoring of their safety, efficacy and effectiveness (tables are included on changing from one method to another to preserve contraceptive protection). We must inform about emergency contraception and propose it in the event of unprotected intercourse. All this will be done through opportunistic screening without requiring screening for thrombophilia or dyslipidemia, but for arterial hypertension. Pregnancy is an important life experience and the family doctor should not remain oblivious. We must be competent both in the preconception consultation (recommending the intake of folic acid, avoiding exposure to occupational and environmental risks, screening for certain pathologies and assessing the intake of drugs not indicated during pregnancy) and in the monitoring of pregnancy. Whether or not we monitor the pregnancy, we must not disregard its control, taking advantage of this period to promote healthy lifestyles and participating in the intercurrent processes that may occur. Menopause in general and osteoporosis in particular exemplify the strategy of medicalization of vital processes that has been followed from different instances and organizations. In our update we address the prevention and treatment of symptoms secondary to estrogen deprivation. We also propose the prevention of osteoporosis, including carrying out densitometry based on the risk of fracture in the next 10 years, and therefore densitometric screening is not recommended in women under 60 years of age. In risk assessment we recommend the use of the frax tool or better, the calibration of the risk of hip fracture with prevalence data from our setting. We linked the indication for treatment with the Z-Score (bone mineral density compared with women of the same age), as it is a condition associated with aging.

Association between exposure to family planning messages on different mass media channels and the utilization of modern contraceptives among young women in Sierra Leone: insights from the 2019 Sierra Leone Demographic Health Survey. BMC Womens Health 2022; 22:376. [PMID: 36114503 PMCID: PMC9479264 DOI: 10.1186/s12905-022-01974-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 09/13/2022] [Indexed: 11/16/2022] Open
Abstract
Background Access to sexual and reproductive health information enables young women to make appropriate decisions. We examined the association between exposure to family panning messages on different mass media and the use of modern contraceptives among young women in Sierra Leone. Methods This was a secondary analysis of the 2019 Sierra Leone Demographic and Health Survey data of young women aged 15–24 years. Multistage stratified sampling was used to select study participants in the survey. We used multivariable logistic regression to determine the association between exposure to family panning messages on different types mass media channels and utilization of modern contraceptives. All our analyses were done using SPSS version 25. Results Out of 6055 young women, 1506 (24.9%, 95% CI 24.0–26.2) were utilizing a modern contraceptive method with the prevalence higher among urban women (26.5%) compared to rural women (23.1%). Less than half (45.6%) had been exposed to family planning messages on mass media (radio 28.6%, television 10.6%, mobile phones 4.2% and newspapers or magazines 2.2%). Young women who had exposure to family planning messages on radio (AOR: 1.26, 95% CI 1.06–1.50) and mobile phones (AOR: 1.84, 95% CI 1.25–2.69) had higher odds of using modern contraceptives compared to their counterparts without the same exposure. Furthermore, having access to internet (AOR: 1.45, 95% CI 1.19–1.78), working (AOR: 1.49, 95% CI 1.27–1.74), being older (20–24 years) (AOR: 1.75, 95% CI 1.46–2.10), being married (AOR: 0.33, 95% CI 0.26–0.42), having visited a health facility within the last 12 months (AOR: 1.34, 95% CI 1.10–1.63), having secondary (AOR: 2.83, 95% CI 2.20–3.64) and tertiary levels of education (AOR: 3.35, 95% CI 1.83–6.13), higher parity (having above one child) AOR: 1.57, 95% CI 1.19–2.08) and residing in the southern (AOR: 2.11, 95% CI 1.61–2.79), northwestern (AOR: 1.87, 95% CI 1.39–2.52), northern (AOR: 2.11, 95% CI 1.59–2.82) and eastern (AOR: 1.68, 95% CI 1.27–2.22) regions of residence were associated with higher odds of modern contraceptives utilization. Conclusion In Sierra Leon, only one in four young women were using modern contraception and more than half of them had not had any exposure to family planning messages on the different types of mass media channels. Behavior change communicators can prioritize family planning messages using radio, mobile phones and the internet. In order to publicize and encourage young women to adopt healthy behaviours and increase uptake of modern contraceptive.

Abstract
Background In 2014, the Thai government launched a free-of-charge long-acting reversible contraception (LARC) program for Thai female adolescents. However, its acceptance had not been reported. Therefore, this study aimed to describe contraceptive use among women of reproductive age before and after the program was implemented. Methods This retrospective cross-sectional study was carried out from the medical records of 9000 women of reproductive age, who attended the Family Planning Clinic at Maharaj Nakorn Chiang Mai Hospital between 2009 and 2018. The Chi-square test was used to compare the contraceptive methods administered before and after the program was implemented, and binary logistic regression was used to find the factors associated with implant use after completion of the program. Results Depot medroxy progesterone acetate (DMPA) injection was the most popular contraceptive method used among 40.9% of the women. The rates of subdermal implant use were increased significantly after the program was implemented (2.3–9.3%, p < 0.001). Implant use for adolescents aged less than 20 years increased from 2.6% to 56.4%, while DMPA was the most popular method used among adult women at 36.4%. Factors associated significantly with implant use after implement of the program included age of less than 20 years (aOR = 4.17 (CI: 1.84–9.44); p = 0.001) and nulliparity (aOR = 8.55 (CI: 3.77–19.39); p < 0.001). Conclusion This study showed a significant increase in contraceptive implant use after the free-LARC program for adolescents had been applied. Statement of implications Contraceptive implant is the most effective hormonal reversible contraception. Its use rate is low among all age groups, but increased clearly after the free-of-charge program was applied for adolescents.

Abstract
Despite their high efficacy and safety, long-acting contraceptive methods are underutilized among women in some settings because they usually require injection or implantation by healthcare personnel. Here, we report a self-administrable microneedle (MN) patch for the rapid administration of a sustained-release contraceptive hormone delivery system into the skin that increases the simplicity and reliability of the MN delivery. We developed an immediate microneedle detachment system using a porous patch backing that has sufficient strength during MN insertion into skin under compression, but enables immediate detachment (< 1 s) of the MNs due to fracture at the MN - backing interface upon patch removal under tension from the skin surface. After patch application, the removed patch produced no biohazardous sharps waste, and was designed to achieve long-acting contraception by formulating poly(lactic-co-glycolic acid) MNs to slowly release the contraceptive hormone levonorgestrel for up to 1 month. Our combined strategy using immediate MN detachment in the skin and sustained drug delivery from the MNs could facilitate greater access to long-acting contraception by providing a simple and convenient option for self-administered, long-acting contraception.

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
INTRODUCTION Acne is a chronic, inflammatory, and immune mediated disease of pilosebaceous unit, highly prevalent in adolescents. It involves face, trunk, and back; may leave scars and affect quality of life. Early, effective, and safe treatment is the key for disease resolution. Oral isotretinoin is the unique treatment for cure or prolonged remission for moderate and severe acne, preventing psychosocial impact and scars. It inhibits sebaceous glands activity and has anti-inflammatory and immunoregulatory properties. AREAS COVERED We performed a comprehensive literature search on PubMed database, up to March 2020, regarding oral isotretinoin for acne treatment. We synthetized data about acne pathogenesis and mechanism of action, efficacy, and safety of isotretinoin. EXPERT OPINION This drug is effective, despite common, controllable, and reversible mucocutaneous side effects. Serious adverse events are rare and represent individual reactions. Teratogenicity is the most severe, requiring rigorous control. We believe that no other therapeutic option, even topicals combined to oral antibiotics accomplish same results. Recurrence after treatments other than isotretinoin is the rule, prolonging risk of scars, compromising skin appearance, and causing emotional distress in teenagers. If there is no absolute contraindication, isotretinoin should be the first line treatment for moderate to severe inflammatory acne.
