RESUMO

Preterm birth remains the leading cause of mortality among under-5's and is a major contributor to the reduction in quality-of-life adjusted years and reduction in human capital. Globally, there are many interventions and care bundles that aim to reduce the impact of preterm birth once preterm labor has ensued and into the neonatal period; not all of these are applicable in all settings. Here, we introduce the FIGO PremPrep-5 initiative, which aims to disseminate key information on the most simple and effective interventions with the aim of increasing implementation globally. Before delivery, we recommend a course of antenatal corticosteroids, and intrapartum magnesium sulfate. At delivery, we recommend delayed cord clamping. Postnatally, we recommend early feeding with breast milk and immediate kangaroo care. While there are many other interventions that may improve outcomes at the time of labor and after preterm birth, these are clinically effective and relatively inexpensive options that can be practiced in most settings and supplemented with more advanced care. We include examples of a training video and infographics that will be used for dissemination.

RESUMO

OBJECTIVE: We sought to determine if soluble levels of C5b-9, the terminal complement complex, correlate with end-organ injury in preeclampsia. STUDY DESIGN: Project COPA (Complement and Preeclampsia in the Americas), a multi-center observational study in Colombia from 2015 to 2016, enrolled hypertensive pregnant women into four groups: chronic hypertension, gestational hypertension, preeclampsia, and preeclampsia with severe features. Trained coordinators collected clinical data, blood and urine. End-organ injury was defined by serum creatinine ≥ 1.0 mg/dl, aspartate transaminase ≥ 70U/L, platelet count < 150,000/µl, or lactate dehydrogenase ≥ 500 U/L. Data were analyzed by χ2 or Fisher's exact test with significance at P < 0.05. MAIN OUTCOME MEASURE: C5b-9 concentrations in plasma and urine, using enzyme linked immunosorbent assays. RESULTS: In total, 298 hypertensive participants were enrolled. Plasma and urine C5b-9 levels were measured in all participants and stratified by quartile (Q1-4), from lowest to highest C5b-9 concentration. Participants with low plasma C5b-9 levels (Q1) were more likely to have end-organ injury compared to those with higher levels (Q2-Q4) [platelet count < 150,000/µl (20.8% vs. 8.4%, P = 0.01); elevated serum creatinine ≥ 1.0 mg/dl (14.9% vs. 4.5%, P = 0.009)]. In contrast, participants with high urinary C5b-9 levels (Q4) were more likely to have end-organ injury compared to those with lower levels (Q1-Q3) [platelet count < 150,000/µl (19.7% vs. 7.4%, P = 0.003); elevated serum creatinine ≥ 1.0 mg/dl (12.3% vs. 4.4%, P = 0.025)]. CONCLUSION: We identified a pattern of increased urine and low plasma C5b-9 levels in patients with preeclampsia and end-organ injury. Soluble C5b-9 levels may be used to identify complement-mediated end-organ injury in preeclampsia.

RESUMO

Iatrogenic preterm birth is a planned delivery that occurs before 37 weeks of gestation due to maternal and/or fetal causes. However, in some cases, such deliveries also occur with no apparent medical indication. The increasing numbers of iatrogenic preterm deliveries worldwide have led researchers to identify modifiable causes that allow the formulation of preventive strategies that could impact the overall preterm birth rate. The present document contains the FIGO (International Federation of Gynecology and Obstetrics) Working Group for Preterm Birth recommendations, aiming to reduce the rates of iatrogenic preterm birth based on four of the most common clinical scenarios and issues related to iatrogenic preterm delivery. The working group supports efforts to identify the contribution of iatrogenic preterm delivery to the overall preterm birth rate and encourages health authorities to establish preventive measures accordingly. We encourage care providers to maintain single embryo transfer policies to prevent multiple pregnancies as a substantial contributor of iatrogenic preterm birth. The working group also recommends that efforts to reduce unnecessary cesarean sections must be warranted, and mechanisms to ensure the appropriate time of delivery and strengthening of education and communication processes must be pursued.

RESUMO

This chapter aims to provide an evidence-based approach to cervical-ripening methods and induction of labor in high-, middle-, and low-income countries. We will review the epidemiology of induction and will also review pharmacological and mechanical methods of cervical-ripening as well as oxytocin for induction. Lastly, we will review current guidelines of when to determine an induction to be failed.

RESUMO

OBJECTIVE: To evaluate whether C5b-9 concentrations in blood and urine are increased in preeclampsia with severe features. METHODS: The Complement and Preeclampsia in the Americas study is a prospective, multicenter case-control study performed at six centers in Colombia from November 2015 to July 2016. The case group included women with preeclampsia with severe features, and the control group included women who were healthy or had chronic hypertension, gestational hypertension, or preeclampsia without severe features. We enrolled two women in the control group for every woman in the case group. Soluble C5b-9 concentrations were measured by enzyme-linked immunosorbent assays in blood and urine. The primary outcome was C5b-9 concentrations in women in the case group compared with all women in the control group, and the secondary outcome was C5b-9 levels in women in the case group compared with individual control subgroups. Differences were assessed by test of medians, and associations were further evaluated by receiver operating characteristic curve analysis and logistic regression with α=0.05. RESULTS: Three hundred fifty-two patients were enrolled. Plasma C5b-9 concentrations did not differ significantly between women in the case group and those in the control group, but urine C5b-9 concentrations were higher in women in the case group (median [interquartile range] 9.9 [1.6-43.7] vs 1.8 [0.54-4.1] ng/mL, P<.001). In subgroup analysis, plasma C5b-9 concentrations were increased in women in the case group compared with healthy women in the control group (median [interquartile range] 2,778 [1,633-4,230] vs 1,374 [1,064-2,332] ng/mL, P<.001), and urine C5b-9 concentrations were increased in women in the case group compared with all control subgroups (P<.001). Using receiver operating characteristic analysis, urine C5b-9 concentrations differentiated preeclampsia with severe features from hypertensive women in the control group (area under the receiver operating characteristic curve 0.74, 95% CI 0.68-0.80). Urine C5b-9 22 ng/mL or greater (range 0-158.4 ng/mL) was the optimal cut point for diagnosis of preeclampsia with severe features with adjusted odds ratio of 10.0 (95% CI 3.5-28.8, P<.001). CONCLUSION: Urinary excretion of terminal complement effector C5b-9 is higher in women with preeclampsia with severe features compared with women with other hypertensive disorders of pregnancy and women without hypertension.
