RESUMEN

The third stage of labor is defined as the time period between delivery of the fetus through delivery of the placenta. During a normal third stage, uterine contractions lead to separation and expulsion of the placenta from the uterus. Postpartum hemorrhage is a relatively common complication of the third stage of labor. Strategies have been studied to mitigate the risk of postpartum hemorrhage, leading to the widespread implementation of active management of the third stage of labor. Initially, active management of the third stage of labor consisted of a bundle of interventions including administration of a uterotonic agent, early cord clamping, controlled cord traction, and external uterine massage. However, the effectiveness of these interventions as a bundle has been questioned, leading to abandonment of some components in recent years. Despite this, upon review of selected international guidelines, we found that the term "active management of the third stage of labor" was still used, but recommendations for and against individual interventions were variable and not necessarily supported by current evidence. In this review, we: (1) examine the physiology of the third stage of labor, (2) present evidence related to interventions that prevent postpartum hemorrhage and promote maternal and neonatal health, (3) review current global guidelines and recommendations for practice, and (4) propose future areas of investigation. The interventions in this review include pharmacologic agents to prevent postpartum hemorrhage, cord clamping, cord milking, cord traction, cord drainage, early skin-to-skin contact, and nipple stimulation. Treatment of complications of the third stage of labor is outside of the scope of this review. We conclude that current evidence supports the use of effective pharmacologic postpartum hemorrhage prophylaxis, delayed cord clamping, early skin-to-skin contact, and controlled cord traction at delivery when feasible. The most effective uterotonic regimens for preventing postpartum hemorrhage after vaginal delivery include oxytocin plus ergometrine; oxytocin plus misoprostol; or carbetocin. After cesarean delivery, carbetocin or oxytocin as a bolus are the most effective regimens. There is inconsistent evidence regarding the use of tranexamic acid in addition to a uterotonic compared with a uterotonic alone for postpartum hemorrhage prevention after all deliveries. Because of differences in patient comorbidities, costs, and availability of resources and staff, decisions to use specific prevention strategies are dependent on patient- and system-level factors. We recommend that the term "active management of the third stage of labor" as a combined intervention no longer be used. Instead, we recommend that "third stage care" be adopted, which promotes the implementation of evidence-based interventions that incorporate practices that are safe and beneficial for both the woman and neonate.

RESUMEN

The large-scale initiatives to address the global unmet needs for family planning (FP) have gathered and compelled scientists, providers, program managers, and other stakeholders (including users) to re-examine the various methods of modern contraception, focusing on those that are proven to be more effective (long-acting reversible contraceptives and permanent methods), historically more widely used (oral contraceptives, condoms), and in development (male hormonal contraception). Implementing FP programs requires an understanding of the human rights principles underpinning the delivery of contraceptive services, the various indicators related to demand, need, and use (demand satisfied, unmet need, and contraceptive prevalence), and its effectiveness (perfect or correct use and typical use), which will be presented in this article. Tools and guidance documents developed using the best available evidence have also been listed in this review article. This issue will also look at new initiatives about providing care (self-care), and key population groups (post-pregnancy and adolescence). The clinical use of the methods should go hand in hand with the programmatic initiatives to ensure that women, men, or couple take up the appropriate method of choice and continue using these based on their reproductive health goals.

RESUMEN

BACKGROUND: Adolescents in the Philippines face many legal, social and political barriers to access sexual and reproductive health (SRH) services, putting them at higher risk of unplanned pregnancy, abortion, sexually transmitted infections and HIV, and other health and development problems. OBJECTIVE: This study aims to evaluate whether current normative documents on SRH in the Philippines are in concurrence with adolescents' human rights principles using the World Health Organization (WHO) Guidance and Recommendations on ensuring human rights in the provision of contraceptive information and services. METHODS: The review focused on policies and normative guidance documents which included the national reproductive health law, its implementing rules and regulations, and the Supreme Court decisions on the law, and documents cited in the government's Adolescent and Youth Health Programme. Also included were documents identified through keyword searches in an online database of the health department. We assessed these documents on their agreement or non-agreement with WHO recommendations, and the presence or absence of adolescent-specific content. RESULTS: Of nine WHO summary recommendations, Philippine normative documents are in agreement with four, namely on acceptability, participation, accountability, and quality, and have adolescent-specific provisions in three. Philippine normative documents are partly in agreement with the remaining five WHO summary recommendations-nondiscrimination, availability, accessibility, informed decision-making, and privacy. Of twenty-four WHO sub-recommendations, Philippine normative documents are in agreement with fifteen, not in agreement with five, and partly in agreement with four. Two possible factors may explain the many documents with conflicting contents: devolution of the Philippine health system, and the deep social and policy divide on sexual and reproductive health. CONCLUSION: Many Philippine-governmental norms and standards are in agreement with adolescents' human rights to contraceptive information and services as recommended by the WHO. However, a significant number are restrictive, reflecting the strong influence of conservative religious beliefs. RECOMMENDATIONS: We recommend: 1) further elaboration of the laws and policies that are fully in agreement with WHO recommendations; 2) a more liberal interpretation of the law to ensure the provision, delivery and access to reproductive health care services, and to promote, protect and fulfill women's reproductive health and rights; and 3) popularization of ethical and human rights norms.

RESUMEN

OBJECTIVE: To estimate the effect of increased body weight and body mass index (BMI) on pregnancy rates with levonorgestrel (LNG) 1.5mg used as emergency contraception (EC). METHODS: The study reviewed data from 6873 women in four WHO-HRP randomized trials on EC conducted between 1993 and 2010. Participants took either 1.5mg of LNG as a single dose or in two doses 12h apart, up to 120h of unprotected intercourse. Contraceptive efficacy (pregnancy rates) at different weight and BMI categories was evaluated. RESULTS: Overall pregnancy rate was low at 1.2%. Pregnancy rates were also low in women weighing over 80kg (0.7%) and who were obese (BMI over 30kg/m2) (2.0%). The pooled analyses for pregnancy demonstrated that BMI over 30kg/m2 decreased efficacy significantly (odds ratio 8.27, 95% confidence interval = 2.70-25.37) when compared to women in lower BMI categories, mainly influenced by pregnancies in obese women from one study site. Sensitivity analyses excluding that site showed that obesity was no longer a risk factor; however, the other studies included too few obese women in the sample to exclude a substantial decrease in efficacy. CONCLUSIONS: Pregnancy rates with use of LNG 1.5mg for EC were low at less than 3% across different weight and BMI categories. Pooled analyses showed an increase in pregnancy rates among obese women (BMI more than 30kg/m2) compared to women with normal BMI levels, influenced by pregnancies all coming from one study site. IMPLICATIONS: Access to LNG as EC should still be promoted to women who need them, and not be restricted in any weight or BMI category, with additional attention for counselling and advice for obese women.

RESUMEN

CONTEXT: The development of a safe and effective reversible method of male contraception is still an unmet need. OBJECTIVE: Evaluation of suppression of spermatogenesis and contraceptive protection by coadministered im injections of progestogen and testosterone. DESIGN: Prospective multicentre study. SETTING: Ten study centers. PARTICIPANTS: Healthy men, aged 18-45 years, and their 18- to 38-year-old female partners, both without known fertility problems. INTERVENTION: Intramuscular injections of 200-mg norethisterone enanthate combined with 1000-mg testosterone undecanoate, administered every 8 weeks. MAIN OUTCOMES MEASURES: Suppression of spermatogenesis by ejaculate analysis, contraceptive protection by pregnancy rate. RESULTS: Of the 320 participants, 95.9 of 100 continuing users (95% confidence interval [CI], 92.8-97.9) suppressed to a sperm concentration less than or equal to 1 million/mL within 24 weeks (Kaplan-Meier method). During the efficacy phase of up to 56 weeks, 4 pregnancies occurred among the partners of the 266 male participants, with the rate of 1.57 per 100 continuing users (95% CI, 0.59-4.14). The cumulative reversibility of suppression of spermatogenesis after 52 weeks of recovery was 94.8 per 100 continuing users (95% CI, 91.5-97.1). The most common adverse events were acne, injection site pain, increased libido, and mood disorders. Following the recommendation of an external safety review committee the recruitment and hormone injections were terminated early. CONCLUSIONS: The study regimen led to near-complete and reversible suppression of spermatogenesis. The contraceptive efficacy was relatively good compared with other reversible methods available for men. The frequencies of mild to moderate mood disorders were relatively high.

RESUMEN

With the renewed focus on family planning, a clear and transparent understanding is needed for the consistent classification of contraceptives, especially in the commonly used modern/traditional system. The World Health Organization Department of Reproductive Health and Research and the United States Agency for International Development (USAID) therefore convened a technical consultation in January 2015 to address issues related to classifying contraceptives. The consultation defined modern contraceptive methods as having a sound basis in reproductive biology, a precise protocol for correct use and evidence of efficacy under various conditions based on appropriately designed studies. Methods in country programs like Fertility Awareness Based Methods [such as Standard Days Method (SDM) and TwoDay Method], Lactational Amenorrhea Method (LAM) and emergency contraception should be reported as modern. Herbs, charms and vaginal douching are not counted as contraceptive methods as they have no scientific basis in preventing pregnancy nor are in country programs. More research is needed on defining and measuring use of emergency contraceptive methods, to reflect their contribution to reducing unmet need. The ideal contraceptive classification system should be simple, easy to use, clear and consistent, with greater parsimony. Measurement challenges remain but should not be the driving force to determine what methods are counted or reported as modern or not. Family planning programs should consider multiple attributes of contraceptive methods (e.g., level of effectiveness, need for program support, duration of labeled use, hormonal or nonhormonal) to ensure they provide a variety of methods to meet the needs of women and men.
