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.

Review
BACKGROUND
Use of contraception lowers a woman's risk of experiencing an ectopic pregnancy. In the case of method failure, however, progestin-only contraceptives may be more likely to result in ectopic pregnancies than some other methods such as combined hormonal and barrier contraceptives.
OBJECTIVE
To describe ectopic pregnancy risk associated with use of implants and progestin-only injectable contraceptives through a systematic review of published studies.
DATA SOURCES
We searched electronic databases for articles in any language published through May 2015 describing studies of progestin-only injectables and implants. We also searched bibliographies and review articles for additional studies.
STUDY SELECTION AND EXTRACTION
Studies that reported any pregnancies were included in the review. Independent data extraction was performed by two authors based on predefined data fields, and where possible, we calculated the proportion of pregnancies that were ectopic and the ectopic pregnancy incidence rate per 1000 woman-years.
RESULTS
Fifty-three studies of implants and 28 studies of injectables were identified; 79% reported pregnancy location. The proportion of ectopic pregnancy ranged from 0 to 100% with an incidence of 0-2.9 per 1000 woman-years in studies of marketed levonorgestrel implants. Studies of etonogestrel implants and the injectables, depot-medroxyprogesterone acetate and norethisterone enanthate, reported few ectopic pregnancies.
CONCLUSION
Progestin-only contraceptive implants and injectables protect against ectopic pregnancy by being highly effective in preventing pregnancy overall; however, the absolute risk of ectopic pregnancy varies by type of progestin. Risk of ectopic pregnancy should not be a deterrent for use or provision of these methods.

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.

Comparative Study Meta-Analysis Review
BACKGROUND
Endometriosis is the presence of functional endometrial tissue in the pelvic peritoneum and it affects several age groups. That is why the impact of endometriosis in quality of life is considerable. The objective of this study was to evaluate the effectiveness of dienogest in patients with pelvic pain associated to endometriosis (PPAE).
METHODS
The evaluation of the effectiveness was carried out through a systematic review using the Cochrane methodology. It was used Markov model, which considers two states of health (with and without PPAE), with the possibility of weekly transition. Women between 18 and 45 years with PPAE were included, in a temporary horizon of 26 weeks. A level of statistical significance of 95% was used for a p < 0.05, with a multivariate probabilistic analysis of sensibility, as well as a univariate analysis of sensibility in several scenarios.
RESULTS
The probability that the female patient did not experience PPAE with the initial treatment was 87.91% with dienogest, 80.07% with danazol, 84.93% with medroxyprogesterone (injectable and oral) and 89.17% with gosereline. The probability that the female patient abandoned her initial treatment was 9% with dienogest, 12.07% with danazol, 9.6 and 6.75% with medroxyprogesterone injectable and oral, respectively, and 10.8 and 3.6% 3-monthly and monthly with gosereline.
CONCLUSION
Compared to danazol, medroxiprogesterone and gosereline, dienogest is the most efficient alternative to treat PPAE.

Contraception May 2024To summarize and update information regarding drug-drug interactions (DDIs) between antiretrovirals (ARVs) and hormonal contraceptives (HCs). (Review)
Review
OBJECTIVE
To summarize and update information regarding drug-drug interactions (DDIs) between antiretrovirals (ARVs) and hormonal contraceptives (HCs).
DESIGN
Systematic review METHODS: We searched seven databases for peer-reviewed publications from January 1, 2015, through December 31, 2023, including studies of women using ARVs and HCs concurrently with outcomes including therapeutic effectiveness or toxicity, pharmacokinetics (PK), or pharmacodynamics. We summarized findings and used checklists to assess evidence quality.
RESULTS
We included 49 articles, with clinical, ARV or HC PK outcomes reported by 39, 25, and 30 articles, respectively, with some articles reporting outcomes in two or more categories. Fifteen of 18 articles assessing DDIs between efavirenz and progestin implants, emergency contraception, or combined hormonal intravaginal rings found higher pregnancy rates, luteal progesterone levels suggesting ovulation, or reduced progestin PK values. Five studies documented that CYP2B6 single nucleotide polymorphisms exacerbated this DDI. One cohort detected doubled bone density loss with concomitant depot medroxyprogesterone acetate (DMPA) and tenofovir disoproxil fumarate (TDF)-containing ART use versus TDF alone. No other studies described DDIs impacting clinical outcomes. Few adverse events were attributed to ARV-HC use with none exceeding Grade 2. Evidence quality was generally moderate, with dis-similar treatment and control groups, identifying and controlling for confounding, and minimizing attrition bias in the study design being the most frequent limitations.
CONCLUSION
Most ARVs and HCs may be used safely and effectively together. TDF-DMPA DDIs warrant longer-term study on bone health and consideration of alternate combinations. For efavirenz-based ART, client counselling on relative risks, including both potential increase in pregnancy rate with concomitant efavirenz and implant use and lower pregnancy rates compared to other HCs even with concomitant efavirenz use, should continue to allow users comprehensive method choice.

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 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
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
CONTEXT
Depot medroxyprogesterone acetate (DMPA), a progestogen-only contraceptive injectable, has traditionally been formulated as a crystalline suspension delivered intramuscularly (IM) at a dose of 150mg/1.0mL. A new, lower dose formulation of DMPA (104mg/0.65mL) has been developed for subcutaneous administration (SC). Given its increasing global availability and public health relevance, DMPA-SC was prioritized for inclusion as a new method referenced in the World Health Organization (WHO) Medical Eligibility Criteria for Contraceptive Use (MEC), 5th Edition.
OBJECTIVE
This systematic review evaluated the published peer-reviewed literature regarding the safety of DMPA-SC among women with various characteristics or medical conditions. Results of this review informed the decision-making of a WHO Guideline Development Group in order to include recommendations on contraceptive eligibility within the revised MEC.
METHODS
We searched PubMed and Cochrane Library databases to identify all relevant evidence published in peer-reviewed journals regarding the safety of DMPA-SC when used by women of reproductive age, particularly those with select characteristics or conditions specified in the MEC, from inception through June 2015. The quality of each individual study was assessed using the system for grading evidence developed by the United States Preventive Services Task Force.
RESULTS
Fourteen studies met criteria for inclusion. Ten reported results relevant to DMPA users of varying age or with obesity, endometriosis or HIV; four compared the safety of DMPA-SC and DMPA-IM when used by general populations of healthy women. A randomized trial evaluating changes in bone mineral density among adult DMPA-SC and DMPA-IM users demonstrated no differences at 2years of follow-up. Limited evidence reported no consistent differences in weight change or bleeding patterns according to age; however, adolescents (<18years) were not included in any studies. Similar contraceptive efficacy, weight change, bleeding patterns and occurrence of other adverse effects among obese and nonobese DMPA-SC users were observed. Women with endometriosis using DMPA-SC over 6months had minimal decreases in bone mineral density, weight gain, few serious adverse events and experienced improved pain symptoms. Women living with HIV tolerated injection of DMPA-SC with rare complications. DMPA-SC and DMPA-IM also show therapeutic equivalence and similar effects on weight gain, changes in bleeding patterns and reports of other adverse effects when these different delivery systems were used by general populations of women.
CONCLUSION
Evidence for use of DMPA-SC by women with select conditions and characteristics including age, obesity, endometriosis or HIV demonstrates that this method can generally be used safely in these contexts. Further, DMPA-SC and DMPA-IM appear to be therapeutically equivalent with similar safety profiles when used by healthy women.

Meta-Analysis
IMPORTANCE
Long-term sleep disturbances in menopausal women are closely related to cardiovascular disorders, metabolic disorders, and cognitive impairment. At present, hormone therapy (HT) is a standard treatment for menopausal symptoms. However, it remains unclear whether HT can improve sleep quality.
OBJECTIVE
We did a systematic review and meta-analysis to assess the effects of different HT regimens on menopausal sleep quality.
EVIDENCE REVIEW
We systematically searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, PsycINFO, CINAHL, and Web of Science for randomized controlled trials of menopausal HT on sleep disturbances up to June 14,2021. Information about ongoing and unpublished trials was collected by searching WHOICTRP and ClinicalTrials.gov. Our primary outcome was sleep quality with objective measurements. We estimated the standardized mean difference (SMD) using random-effects models.
FINDINGS
We identified a total of 3,059 studies and finally included 15 studies in the meta-analysis. Compared with placebo, HT improved self-reported sleep outcomes (SMD = -0.13; 95% CI, -0.18 to -0.08, P < 0.00001 and I2 = 41%), but not sleep parameters measured by polysomnography. Subgroup analyses according to the regimen of HT showed that 17β-estradiol (17β-E2) (SMD = -0.34; 95% CI, -0.51 to -0.17, P < 0.0001, and I2 = 0%) and conjugated equine estrogens (SMD = -0.10; 95% CI, -0.12 to -0.07, P < 0.00001, and I2 = 0%) improved sleep quality. Moreover, transdermal administration (SMD = -0.35; 95% CI, -0.64 to -0.06, and P = 0.02) was more beneficial than oral (SMD = -0.10; 95% CI, -0.14 to -0.07, and P < 0.00001). In addition, the combination of estrogen and progesterone had a positive effect on sleep disturbance (SMD = -0.10; 95% CI, -0.13 to -0.07, P < 0.00001, and I2 = 0%), while estrogen monotherapy did not. The results showed that estrogen/micronized progesterone (SMD = -0.22; 95% CI, -0.37 to -0.06, P = 0.007, and I2 = 0%) and estrogen/medroxyprogesterone acetate (SMD = -0.10; 95% CI, -0.13 to -0.07, P < 0.00001, and I2 = 0%) could alleviate sleep disturbance.
CONCLUSIONS AND RELEVANCE
HT has a beneficial effect on sleep disturbance to some extent, and the formulations and routes of administration of hormonal agents influence the effect size.
