Meta-Analysis Review
INTRODUCTION AND HYPOTHESIS
Hormonal contraceptive use is common practice worldwide. Although the effects of hormone treatments in the pelvic region are well established, there is no clear evidence regarding their effects on incontinence, bladder, bowel, vaginal and sexual symptoms in premenopausal women. We hypothesized that hormonal contraceptives affect pelvic floor function. We therefore performed a comprehensive systematic review of published studies to determine the influence of hormonal contraception on pelvic floor functions.
METHODS
Electronic literature databases were searched from database inception to March 2015. Keywords and medical subject headings searched for included terms and word variations for 'contraception', and 'bowel', 'vaginal', 'sexual' and 'urinary' symptoms. Studies were eligible if they looked at these symptoms in women taking hormonal contraception. Two reviewers independently screened studies for inclusion, and extracted data on study characteristics, quality and results. Data were combined where possible.
RESULTS
Of the 429 citations identified, 13 studies were included in the review. Data were meta-analysed where possible and presented as prevalence. The results indicate statistically significant links between interstitial cystitis and oral contraceptive use at any point (ever) (OR 2.31, 95 % CI 1.03 - 5.16; p = 0.04) and vulvar vestibulitis and current oral contraceptive use (OR 2.10, 95 % CI 1.26 - 3.49; p = 0.004). The evidence is unclear in other areas.
CONCLUSIONS
Our results indicate that oral contraceptives may have an effect on pelvic floor function. They could increase the risk of painful bladder and vulvar vestibulitis, but their effect on dyspareunia is inconsistent. However, robustly collected prospective data to establish causal associations are needed.

Meta-Analysis Review
OBJECTIVE
As the HIV/AIDS epidemic continues to spread in Africa and Asia, use of the injectable contraceptive steroid DMPA is widespread and has been increasing. Since studies dating back to 1992 have suggested that DMPA may increase the transmission of HIV to women, we endeavored to determine if the extant epidemiological and biological evidence is sufficient to conclude that DMPA use constitutes a definite hazard to women's health.
METHODS
We searched Medline using the search terms: contraceptives or contraception AND HIV and searched bibliographies of articles thus identified. We included in the meta-analysis all studies examining the association between use of DMPA (or injectable contraceptives comprising mostly DMPA) and the presence (cross-sectional studies, n = 8) or acquisition (longitudinal studies, n = 16) of HIV+ status in women, using a random effects models to estimate odds ratios (ORs; cross-sectional studies) and hazard ratios (HRs; longitudinal studies). Studies were excluded if the comparison group included women using any form of steroidal contraception.
RESULTS
Statistically significant positive associations between DMPA use and HIV positivity were observed both in cross-sectional (OR = 1.41, 95% CI 1.15 - 1.73) and longitudinal studies (HR = 1.49, 95% CI 1.28 - 1.73). The biological plausibility of increased vulnerability to HIV infection due to progestational action (via thinning of the vaginal epithelial barrier and immunosuppression) as well as glucocorticoid agonistic immunosuppression, are discussed.
CONCLUSION
The epidemiological and biological evidence now make a compelling case that DMPA adds significantly to the risk of male-to-female HIV transmission.

Meta-Analysis
OBJECTIVE
To examine the effectiveness of progestin re-treatment for recurrent endometrial intraepithelial neoplasia (EIN), atypical endometrial hyperplasia (AH) and endometrial cancer (EC) following initial fertility-sparing treatment.
METHODS
A comprehensive systematic review and meta-analysis were conducted by an Expert Panel of the Japan Society of Gynecologic Oncology Endometrial Cancer Committee. Multiple search engines, including PubMed/MEDLINE and the Cochrane Database, were searched in December 2021 using the keywords "Endometrial neoplasms," "Endometrial hyperplasia," "Endometrial intraepithelial neoplasia," "Fertility preservation," "Progestins," AND "Recurrence." Cases describing progestin re-treatment for recurrent EIN, AH and EC were compared with cases that underwent conventional hysterectomy. The primary outcomes were survival and disease recurrence, and the secondary outcome was pregnancy.
RESULTS
After screening 238 studies, 32 with results for recurrent treatment were identified. These studies included 365 patients (270 received progestin re-treatment and 95 underwent hysterectomy). Most progestin re-treatment involved medroxyprogesterone acetate or megestrol acetate (94.5%). Complete remission (CR) following progestin re-treatment was achieved in 219 (81.1%) cases, with 3-, 6- and 9-month cumulative CR rates of 22.8%, 51.7% and 82.6%, respectively. Progestin re-treatment was associated with higher risk of disease recurrence than conventional hysterectomy was (odds ratio [OR]=6.78; 95% confidence interval [CI]=1.99-23.10), and one patient (0.4%) died of disease. Fifty-one (14.0%) women became pregnant after recurrence, and progestin re-treatment demonstrated a possibility of pregnancy (OR=2.48; 95% CI=0.94-6.58).
CONCLUSION
This meta-analysis suggests that repeat progestin therapy is an effective option for women with recurrent EIN, AH and EC, who wish to retain their fertility.

Meta-Analysis
BACKGROUND
Atypical polypoid adenomyoma (APA) is a rare uterine tumor typically found in fertile age and associated with infertility. Among young nullipara women, conservative treatment is proposed despite the high recurrence rate and the association with endometrial cancer.Our aim was to assess the risk of recurrence with different conservative treatments in fertile ages and the prevalence of malignant or pre-malignant associated lesions to better address an adequate patient counselling when treatment modalities are discussed.
METHODS
This study is a systematic review and meta-analysis of case reports and case series about APA management and follow-up. A literature search was carried from Medline and Scopus for studies published from January 1, 1980 to December 31, 2018.
RESULTS
We included 46 observational studies and 296 cases in fertile women. The prevalence of APA relapse was 44% (CI.95 33-57%) and was lower in cases treated with operative hysteroscopy (22%; CI.95 11-39%) than in cases treated with blind curettage and polypectomy (38%; CI.95 15-67%). The prevalence of the concomitant or during the follow-up diagnosis of endometrial carcinoma was 16% (CI.95 9-29%). The risk of cancer development during follow-up was significantly less in cases treated with histeroscopy (10.56% new cumulative diagnosis at 5 years follow up; CI.95 0-23.7%) than blind curettage and polypectomy (35.5% new cumulative diagnosis at 5 years; CI.95 11.65-52.92%; P < .05). Medical treatment with medroxyprogesterone acetate after surgery does not reduce APA recurrence. Pregnancy was observed in 79% cases in which the desire was expressed.
CONCLUSION
This review suggests that conservative treatment performed by operative hysteroscopy is the optimal choice because it lowers the risk of recurrence, improves the accuracy of concomitant carcinoma or hyperplasia diagnosis, and leaves the possibility of future pregnancies.

Review
BACKGROUND
Postpartum women need effective contraception. Concerns have been raised that use of progestogen-only contraceptives (POCs) may affect breastfeeding performance and infant health outcomes.
OBJECTIVES
We investigated the clinical outcomes of breastfeeding duration, initiation of supplemental feeding and weaning, as well as infant outcomes including infant growth, health and development among breastfeeding women using POCs compared with breastfeeding women not using POCs.
SEARCH STRATEGY
We searched the PubMed database for all articles published from database inception through December 2014.
SELECTION CRITERIA
We included primary research studies of breastfeeding women of any age or parity who received POCs, including progestogen-only pills, injectables, implants or hormonal intrauterine devices (IUDs). The main outcomes were breastfeeding performance (as measured by initiation, continuation, frequency and exclusivity of breastfeeding) and infant health (as measured by growth, development or adverse health effects).
RESULTS
Forty-nine articles reporting on 47 different studies were identified that investigated the use of POCs in breastfeeding women and reported clinically relevant outcomes of infant growth, health or breastfeeding performance. Studies ranged from poor to fair methodological quality and generally failed to show negative effects of the use of POCs on breastfeeding outcomes or on infant growth or development. One randomized controlled trial (RCT) raises concerns that immediate insertion of the levonorgestrel IUD postpartum may be associated with poorer breastfeeding performance when compared with delayed insertion, although two other RCTs evaluating early etonogestrel implants compared with delayed initiation of implants or depot medroxyprogesterone acetate failed to find such an association.
CONCLUSION
The preponderance of evidence fails to demonstrate adverse breastfeeding outcomes or negative health outcomes in infants such as restricted growth, health problems or impaired development. Evidence newly added to this review was largely consistent with previous evidence.

Meta-Analysis Review
OBJECTIVE AND DESIGN
Some studies suggest that specific hormonal contraceptive methods [particularly depot medroxyprogesterone acetate (DMPA)] may increase women's HIV acquisition risk. We updated a systematic review to incorporate recent epidemiological data.
METHODS
We searched for articles published between 15 January 2014 and 15 January 2016 and hand-searched reference lists. We identified longitudinal studies comparing users of a specific hormonal contraceptive method against either nonusers of hormonal contraception or users of another specific hormonal contraceptive method. We added newly identified studies to those in the previous review, assessed study quality, created forest plots to display results, and conducted a meta-analysis for data on DMPA versus non-use of hormonal contraception.
RESULTS
We identified 10 new reports of which five were considered 'unlikely to inform the primary question'. We focus on the other five reports, along with nine from the previous review, which were considered 'informative but with important limitations'. The preponderance of data for oral contraceptive pills, injectable norethisterone enanthate, and levonorgestrel implants do not suggest an association with HIV acquisition, though data for implants are limited. The new, higher quality studies on DMPA (or nondisaggregated injectables), which had mixed results in terms of statistical significance, had hazard ratios between 1.2 and 1.7, consistent with our meta-analytic estimate for all higher quality studies of hazard ratio 1.4.
CONCLUSION
Although confounding in these observational data cannot be excluded, new information increases concerns about DMPA and HIV acquisition risk in women. If the association is causal, the magnitude of effect is likely hazard ratio 1.5 or less. Data for other hormonal contraceptive methods, including norethisterone enanthate, are largely reassuring.

Review
STUDY OBJECTIVE
Adolescents are at high risk for unintended pregnancies. Although intrauterine devices (IUDs), long-acting reversible contraceptives (LARCs), are known to be highly effective in preventing pregnancy, little is known about IUD adherence in adolescents. In this systematic review (SR) we examined IUD continuation rates compared with other forms of contraception in young women aged 25 years and younger. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A systematic search of Ovid Medline, Cochrane Library, and Embase was conducted for the years 1946-2015. Included studies examined IUD use in women 25 years of age and younger, compared IUD use with another form of contraception, and measured continuation rates at 12 months. The quality of each study was appraised using the Downs and Black criteria, and 12-month continuation rates among studies were pooled and analyzed according to contraceptive type.
RESULTS
Of 3597 articles retrieved, 9 studies met criteria for SR. Synthesized across studies, 12-month continuation was significantly higher for IUD users (86.5%, 12,761/14,747) compared with oral contraceptives (39.6%, 1931/4873), Depo-Provera (Pfizer Inc, New York, NY) hormonal injection (39.8%, 510/1282), vaginal ring (48.9%, 196/401), and transdermal patch (39.8%, 37/93; all P values < .001). There was no statistically significant difference in 12-month continuation between the IUD and another LARC method, the subdermal etonogestrel implant (85.3%, 4671/5474).
CONCLUSION
Findings of this SR suggest that continuation rates for IUDs are generally higher compared with other contraceptive methods for women aged 25 years and younger. In a population with high rates of unintended pregnancies, generally low adherence, and imperfect use with other non-LARCs, IUD use should be encouraged.

CONTEXT
The objective of this systematic review was to update a prior review and summarize the evidence on the impact of family planning reminder systems (e.g., daily text messages reminding oral contraception users to take a pill).
EVIDENCE ACQUISITION
Multiple databases, including PubMed, were searched during 2016-2017 for articles published from March 1, 2011, to November 30, 2016, describing studies of reminder systems.
EVIDENCE SYNTHESIS
The search strategy identified 24,953 articles, of which two studies met the inclusion criteria. In total with the initial review, four studies (including two RCTs) examined reminder systems among oral contraception users, with two of three that examined correct use finding a statistically significant positive impact, and one RCT finding a positive impact on knowledge and continuation. Of three studies (including two RCTs) that examined reminder systems among depot medroxyprogesterone acetate users, one of three that examined correct use found a statistically significant positive impact on timely injections at 3 months, and one study found no effect on continued use at 12 months.
CONCLUSIONS
Although this review found mixed support for the effectiveness of reminder systems on family planning behaviors, the highest quality evidence yielded null findings related to correct use of oral contraception and timely depot medroxyprogesterone acetate injections beyond 3 months, and found positive findings related to oral contraception continuation and knowledge. Future studies would be strengthened by objectively measuring outcomes and examining additional contraceptive methods and outcomes at least 12 months post-intervention.

Review
OBJECTIVE
This systematic review was conducted to provide up-to-date evidence on the safety and effectiveness of task sharing in the delivery of modern contraceptives. . The review followed the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines. We searched Medline, Embase, Cochrane CENTRAL, and Google Scholar for peer-reviewed studies that reported on effectiveness and/or safety outcomes of task sharing of any modern contraceptive method. Only Cochrane Effective Practice of Organizations of Care (EPOC) study designs were eligible, and quality assessment of the evidence was performed using the Cochrane risk of bias (RoB) tools. Meta-analyses, where possible, were carried out using Stata, and certainty of the evidence for outcomes was assessed using the Grading of Recommendations Assessment, Development, and Evaluation tool (GRADE).
RESULTS
Six studies met the inclusion criteria: five reported on self-injection of subcutaneous depot medroxyprogesterone acetate (DMPA-SC) compared to administered by trained health providers; and one assessed tubal ligation performed by associate clinicians compared to advanced-level associate clinicians. Self-injection improved contraceptive continuation, with no increase in unintended pregnancy and no difference in side effects compared to provider administered. In tubal ligation, the rate of adverse events, time to complete procedure, and participant satisfaction were similar among associate clinicians and advanced clinicians.
CONCLUSION
The evidence suggests that self-injection of DMPA-SC and tubal ligation performed by associate clinicians are safe and effective. These findings should be complemented with the evidence on the feasibility and acceptability of task sharing of these methods. The review protocol was registered with PROSPERO CRD42021283336.

Review
OBJECTIVE
To perform a systematic review of the literature to examine original research on contraception in women with cystic fibrosis (CF) with a specific focus on safety, efficacy, non-contraceptive benefits, and utilization patterns in this population.
STUDY DESIGN
We searched PubMed and Embase databases for any peer-reviewed original research in English on the use of contraception in women with CF.
RESULTS
We identified 241 unique citations. After title review and exclusion of articles not reporting original data, 18 publications were included in the final review, with at least two articles for each area of focus. Limited evidence indicates that oral contraceptive pills are likely safe and efficacious in women with CF. Hormonal contraception may reduce pulmonary exacerbation rates and decrease need for antibiotics, suggesting non-contraceptive benefits. Women with CF utilize birth control at similar rates as the general population, and oral contraceptive pills and condoms are the most commonly used methods.
CONCLUSIONS
Data on the safety, efficacy, and non-contraceptive benefits of hormonal contraception in women with CF are scant. Based on the limited data, hormonal contraception seems to be safe and efficacious and may provide noncontraceptive benefits. Further high-quality data from disease-specific research are required to better inform contraceptive decision-making among women with CF.
