Clinical practice guidelines for contraception by the French National College of Gynecologists and Obstetricians (CNGOF)

Contraception and diabetes: Which modalities should we consider in 2021?

Diabetes affects many women of reproductive age. Choice of contraceptive method is essential in order to combine efficacy and the patient's wishes, while taking into account the potential side effects. In this review, we will discuss the different methods available for women with diabetes, focusing the discussion on their metabolic and general effects. We will not discuss the side effects and contraindications common to all women, whether they have diabetes or not. The objective is to try to identify an algorithm to help in the decision to choose the most suitable contraceptive method for women with type 1 or type 2 diabetes.

Study on the use practices and knowledges of French practitioners about the use of intra-uterine devices in early post-partum contraception in France

OBJECTIVES

Intra-Uterine Device (IUD) insertion is possible in early postpartum. Although this contraception method is recognized and used in lots of country, it seems infrequent and poorly known in France. Our study aims to assess the barriers to the application of this method in France.

METHODS

A questionnaire was sent to obstetricians-gynaecologist professionals and midwives in France, through the affiliation to CNGOF (French National College of Obstetricians and Gynecologists) and to CNSF (French National College of Midwives). Questions were focused on the practices and knowledge about the insertion of IUD in early postpartum.

RESULTS

four hundred eight practitioners responded. Amongst them, 63% knew about the possibility to use IUDs after a vaginal delivery and 31% knew it could be inserted during cesarean section. Ten percent of them used this method. Most of these practitioners (80% of them) would like to discuss the insertion of an IUD in early postpartum with their patients and 71% would like to perform the insertion themselves after training. Besides, this study shows that contraception is rarely addressed by physicians during the follow-up of pregnancies. Less than 15% of respondents report discussing the topic systematically with the patient during the pregnancy follow during pregnancy follow.

CONCLUSION

insertion of IUDs in early postpartum is uncommon in France. The main limitation seems to be a lack of knowledge, but practitioners seem to be interested in this practice. Training courses could be created in order to rase up the adoption of this practice.

[Contraception in women with obesity]

Obese women are at high risk of unintended pregnancy. In addition, obesity is an important risk factor for venous thromboembolism events and arterial thrombosis. All of these data are to be considered in choosing a contraceptive method for obese women. The metabolic changes and the increased body mass of these women may be the cause of a reduction in the effectiveness of hormonal contraception. The progestin-only contraceptives (progestin only pills and etonogestrel subdermal implant) and the intra-uterine devices are the preferred contraceptive methods in women with obesity. The combined estrogen-progestin contraceptives may be proposed in young obese women without other cardiovascular risk factor. Obesity per se does not seem to increase the risk of failure of most contraceptive methods. Bariatric surgery is a complex situation. Contraception is needed for at least 12 months after surgery. Some bariatric surgery such as bypass can induce gastrointestinal malabsorption. In this situation, all oral contraceptives are not recommended because of a higher risk of failure.

[Contraception for adolescent women]

The request for a contraception in adolescent women makes it possible to address HPV vaccination and prevention of STIs and to search for abuse. Optimizing the use of contraception is the priority. Any contraceptive methods can be offered. Adhesion is improved by prior information and individualized counselling. Apart from the vascular risk associated with the combined hormonal contraception, hormonal contraception provides gynecologic benefits. The efficacy of long-acting methods is higher compared to short-acting methods but their tolerance is a sensitive matter. Emergency contraception can be prescribed in advance. There are measures to facilitate the delivery to minors.

Four cases of heterotopia of an intrauterine device embedded in the bladder muscular layer causing cystolithiasis: case report and review of the literature

Family planning is a basic national policy in China. An intrauterine device (IUD) is an important method of achieving family planning owing to its high safety, low cost, and convenient use. The indwelling birth control ring has no obvious adverse effects on the sexual life of women after the operation, and the process is reversible. This ring can be removed for women who want to have children again. There are approximately 100 million women with IUDs worldwide, with approximately 80 million in China. This finding accounts for approximately 40% of women of childbearing age in China. Although an IUD is safe, the invasive operation inevitably leads to complications, such as pelvic infection, abnormal menstruation, and damage to adjacent organs. Among them, ectopic bladder stone formation is a rare complication, but several related cases have been reported. We report four cases of heterotopia of an IUD and cystolithiasis, with diagnosis based on the medical history, clinical manifestations, imaging, and cystoscopic findings. The four patients with ectopic IUDs were treated with cystoscopy combined with laparoscopy (or hysteroscopy). We describe the process of diagnosis and treatment of our patients, and the related literature on an ectopic IUD is reviewed.

Hormonal contraceptives and the risk of suicide: a systematic review and meta-analysis

OBJECTIVE

To assess the effect of hormonal contraceptive use over the risk of suicide.

METHOD

Systematic review and meta-analysis of observational studies retrieved from five search engines until September 2019, comparing the use of any hormonal contraceptive versus non-hormonal contraceptive use or no use. Primary outcome was consumed suicide, and secondary outcomes were suicidal attempt and ideation. Random effects meta-analyses with the inverse variance method were used to evaluate the effects of exposure over outcomes. Effect was calculated as risk ratio (RR) with their corresponding 95% confidence interval (CI). Risk of bias was assessed with the Newcastle-Otawa Scale.

RESULTS

There were no randomized controlled trials concerning suicide and hormonal contraceptive use. Only three cohort studies (n = 184,721 women), that evaluated the primary outcome (consumed suicide), were included in the meta-analysis. Hormonal contraceptive use was associated to a higher risk of consumed suicide (RR = 1.36, 95% CI 1.06 to 1.75, P =  0.015, I² = 0%). There were no secondary outcomes in at least two cohorts.

CONCLUSION

This meta-analysis found a positive association between hormonal contraceptive use and consumed suicides. Prior to their use, populations at suicidal risk should be properly evaluated.
