Induced Abortion and the Risk of Rh Sensitization.

Importance: While population-level data suggest Rh immunoglobulin is unnecessary before 12 weeks' gestation, clinical evidence is limited. Thus, guidelines vary, creating confusion surrounding risks and benefits of Rh testing and treatment. As abortion care in traditional clinical settings becomes harder to access, many people are choosing to self-manage and need to know if ancillary blood type testing is necessary. Objective: To determine how frequently maternal exposure to fetal red blood cells (fRBCs) exceeds the most conservative published threshold for Rh sensitization in induced first-trimester abortion. Design, Setting, and Participants: Multicenter, observational, prospective cohort study using high-throughput flow cytometry to detect circulating fRBCs in paired maternal blood samples before and after induced first-trimester abortion (medication or procedural). Individuals undergoing induced first-trimester abortion before 12 weeks 0 days' gestation were included. Paired blood samples were available from 506 participants who underwent either medical (n = 319 [63.0%]) or procedural (n = 187 [37.0%]) abortion. Exposure: Induced first-trimester abortion. Main Outcomes and Measures: The primary outcome was the proportion of participants with fRBC counts above the sensitization threshold (125 fRBCs/5 million total RBCs) after induced first-trimester abortion. Results: Among the 506 participants, the mean (SD) age was 27.4 (5.5) years, 313 (61.9%) were Black, and 123 (24.3%) were White. Three of the 506 participants had elevated fRBC counts at baseline; 1 of these patients had an elevated fRBC count following the abortion (0.2% [95% CI, 0%-0.93%]). No other participants had elevated fRBC counts above the sensitization threshold after induced first-trimester abortion. The median change from baseline was 0 fRBCs, with upper 95th and 99th percentiles of 24 and 35.6 fRBCs, respectively. Although there was a strong association between the preabortion and postabortion fRBC counts, no other baseline characteristic was significantly associated with postabortion fRBC count. Conclusions and Relevance: Induced first-trimester abortion is not a risk factor for Rh sensitization, indicating that Rh testing and treatment are unnecessary before 12 weeks' gestation. This evidence may be used to inform international guidelines for Rh immunoglobulin administration following first-trimester induced abortion.

Proteome-defined changes in cellular pathways for decidua and trophoblast tissues associated with location and viability of early-stage pregnancy.

BACKGROUND: In early pregnancy, differentiating between a normal intrauterine pregnancy (IUP) and abnormal gestations including early pregnancy loss (EPL) or ectopic pregnancy (EP) is a major clinical challenge when ultrasound is not yet diagnostic. Clinical treatments for these outcomes are drastically different making early, accurate diagnosis imperative. Hence, a greater understanding of the biological mechanisms involved in these early pregnancy complications could lead to new molecular diagnostics. METHODS: Trophoblast and endometrial tissue was collected from consenting women having an IUP (n = 4), EPL (n = 4), or EP (n = 2). Samples were analyzed by LC-MS/MS followed by a label-free proteomics analysis in an exploratory study. For each tissue type, pairwise comparisons of different pregnancy outcomes (EPL vs. IUP and EP vs. IUP) were performed, and protein changes having a fold change ≥ 3 and a Student's t-test p-value ≤ 0.05 were defined as significant. Pathway and network classification tools were used to group significantly changing proteins based on their functional similarities. RESULTS: A total of 4792 and 4757 proteins were identified in decidua and trophoblast proteomes. For decidua, 125 protein levels (2.6% of the proteome) were significantly different between EP and IUP, whereas EPL and IUP decidua were more similar with only 68 (1.4%) differences. For trophoblasts, there were 66 (1.4%) differences between EPL and IUP. However, the largest group of 344 differences (7.2%) was observed between EP and IUP trophoblasts. In both tissues, proteins associated with ECM remodeling, cell adhesion and metabolic pathways showed decreases in EP specimens compared with IUP and EPL. In trophoblasts, EP showed elevation of inflammatory and immune response pathways. CONCLUSIONS: Overall, differences between an EP and IUP are greater than the changes observed when comparing ongoing IUP and nonviable intrauterine pregnancies (EPL) in both decidua and trophoblast proteomes. Furthermore, differences between EP and IUP were much higher in the trophoblast than in the decidua. This observation is true for the total number of protein changes as well as the extent of changes in upstream regulators and related pathways. This suggests that biomarkers and mechanisms of trophoblast function may be the best predictors of early pregnancy location and viability.

Levonorgestrel 52 mg intrauterine system efficacy and safety through 8 years of use.

BACKGROUND: Extending hormonal intrauterine system duration will allow users to have less need for procedures to provide long-term contraception. OBJECTIVE: This study aimed to evaluate the efficacy and safety of the levonorgestrel 52 mg intrauterine system during years 7 and 8 of use. STUDY DESIGN: A total of 1751 nulliparous and multiparous participants aged 16 to 45 years enrolled in a phase 3, multicenter trial to evaluate the efficacy and safety of the use of the Liletta levonorgestrel 52 mg intrauterine system for up to 10 years. Participants aged 36 to 45 years at enrollment underwent safety evaluation only. After the first year, we evaluated participants every 6 months for intrauterine system location confirmation and urine pregnancy testing at each visit. We assessed the Pearl Indices in years 7 and 8 and the life-table analysis for cumulative pregnancy rates through 8 years of use. For the primary efficacy analyses, all participants aged 16 to 35 years at enrollment were included through year 6; years 7 and 8 included only users aged ≤39 years at the start of each use year. Safety outcomes were assessed in all participants regardless of duration of use. We assessed amenorrhea rates, defined as no bleeding or spotting in the 90 days before the end of the year. RESULTS: After intrauterine system placement, we followed 1568 participants aged 16 to 35 years and 146 participants aged 36 to 45 years. The 16- to 35-year-old participants included 986 (57.5%) nulliparous and 433 (25.3%) obese users. Overall, 569 participants started year 7, 478 completed year 7 (380 aged ≤39 years at beginning of year) and 343 completed year 8 (257 aged ≤39 years at beginning of year); 77 completed 10 years of use. Eleven pregnancies occurred over 8 years, 7 (64%) of which were ectopic. Two pregnancies occurred in year 7 (Pearl Index, 0.49; 95% confidence interval, 0.06-1.78), 1 in a participant with implantation 4 days after a desired removal; no pregnancies occurred in year 8. The cumulative life-table pregnancy rate in the primary efficacy population through year 8 was 1.32 (95% confidence interval, 0.69-2.51); without the postremoval pregnancy, the rate was 1.09 (95% confidence interval, 0.56-2.13). Two perforations (0.1%) occurred, none noted after year 1. Expulsion occurred in 71 (4.1%) participants overall, with 3 in year 7 and 2 in year 8. Pelvic infection was diagnosed in 16 (0.9%) participants during intrauterine system use, 1 each in years 7 and 8. Only 44 (2.6%) participants overall discontinued because of bleeding complaints (4 total in years 7 and 8) with rates per year of 0.1% to 0.5% for years 3 to 8. Amenorrhea rates were 39% at both years 7 and 8. CONCLUSION: The levonorgestrel 52 mg intrauterine system is highly effective over 8 years of use and has an excellent extended safety profile. This report details the longest period of efficacy and safety data for continuous use of a levonorgestrel 52 mg intrauterine system for contraception.

Medical management of early pregnancy loss is cost-effective compared with office uterine aspiration.

BACKGROUND: Early pregnancy loss, also referred to as miscarriage, is common, affecting approximately 1 million people in the United States annually. Early pregnancy loss can be treated with expectant management, medications, or surgical procedures-strategies that differ in patient experience, effectiveness, and cost. One of the medications used for early pregnancy loss treatment, mifepristone, is uniquely regulated by the Food and Drug Administration. OBJECTIVE: This study aimed to compare the cost-effectiveness from the healthcare sector perspective of medical management of early pregnancy loss, using the standard of care medication regimen of mifepristone and misoprostol, with that of office uterine aspiration. STUDY DESIGN: We developed a decision analytical model to compare the cost-effectiveness of early pregnancy loss treatment with medical management with that of office uterine aspiration. Data on medical management came from the Pregnancy Failure Regimens randomized clinical trial, and data on uterine aspiration came from the published literature. The analysis was from the healthcare sector perspective with a 30-day time horizon. Costs were in 2018 US dollars. Effectiveness was measured in quality-adjust life-years gained and the rate of complete gestational sac expulsion with no additional interventions. Our primary outcome was the incremental cost per quality-adjust life-year gained. Sensitivity analysis was performed to identify the key uncertainties. RESULTS: Mean per-person costs were higher for uterine aspiration than for medical management ($828 [95% confidence interval, $789-$868] vs $661 [95% confidence interval, $556-$766]; P=.004). Uterine aspiration more frequently led to complete gestational sac expulsion than medical management (97.3% vs 83.8%; P=.0001); however, estimated quality-adjust life-years were higher for medical management than for uterine aspiration (0.082 [95% confidence interval, 0.8148-0.08248] vs 0.079 [95% confidence interval, 0.0789-0.0791]; P<.0001). Medical management dominated uterine aspiration, with lower costs and higher confidence interval. The probability that medical management is cost-effective relative to uterine aspiration is 97.5% for all willingness-to-pay values of ≥$5600/quality-adjust life-year. Sensitivity analysis did not identify any thresholds that would substantially change outcomes. CONCLUSION: Although office-based uterine aspiration more often results in treatment completion without further intervention, medical management with mifepristone pretreatment costs less and yields similar quality-adjust life-years, making it an attractive alternative. Our findings provided evidence that increasing access to mifepristone and eliminating unnecessary restrictions will improve early pregnancy care.

Pregnant and bleeding: A model to assess factors associated with the need for emergency care in early pregnancy.

OBJECTIVE: To assess the prevalence of Critical or Emergent patient classification among pregnant patients presenting to the Emergency Department (ED) and to identify characteristics that discriminate between patients requiring Emergency care from those who can be safely triaged to the ambulatory setting. STUDY DESIGN: In this cross-sectional study conducted in 3 urban EDs, patients under 16 weeks gestation who presented with bleeding and/or cramping completed a 7-item questionnaire. We compared baseline clinical variables and survey responses among patients classified as Critical or Emergent per the American Board of Emergency Medicine's patient acuity definitions with those classified as Lower Acuity to identify independent risk factors for outcomes. RESULTS: Of 484 participants, 21 (4.3%) were classified as Critical or Emergent and required interventions. While no demographic characteristics differentiated Critical patients from Lower Acuity patients, survey questions associated with a higher likelihood of emergency intervention included history of prior ectopic pregnancy (OR 8.7, 95% CI 3.2-23.5) heavy bleeding in the past two hours (OR 11.8, 95% CI 3.8-36.1), as well as having made a prior ED visit in the current pregnancy (OR 1.9, 95% CI 0.7-5.1). Joint consideration of these risk factors in a multivariable model performed well at discriminating between Critical and Lower Acuity patients with an area under the ROC curve of 0.82 (95% CI 0.71-0.93). CONCLUSION: Patients with a history of ectopic pregnancy, heavy bleeding in the past two hours, and/or prior presentation to the ED in the current pregnancy had the highest risk of needing emergency-level care. The vast majority of patients presenting to the ED with early pregnancy complaints were discharged without intervention.

Mifepristone Pretreatment for the Medical Management of Early Pregnancy Loss.

BACKGROUND: Medical management of early pregnancy loss is an alternative to uterine aspiration, but standard medical treatment with misoprostol commonly results in treatment failure. We compared the efficacy and safety of pretreatment with mifepristone followed by treatment with misoprostol with the efficacy and safety of misoprostol use alone for the management of early pregnancy loss. METHODS: We randomly assigned 300 women who had an anembryonic gestation or in whom embryonic or fetal death was confirmed to receive pretreatment with 200 mg of mifepristone, administered orally, followed by 800 µg of misoprostol, administered vaginally (mifepristone-pretreatment group), or 800 µg of misoprostol alone, administered vaginally (misoprostol-alone group). Participants returned 1 to 4 days after misoprostol use for evaluation, including ultrasound examination, by an investigator who was unaware of the treatment-group assignments. Women in whom the gestational sac was not expelled were offered expectant management, a second dose of misoprostol, or uterine aspiration. We followed all participants for 30 days after randomization. Our primary outcome was gestational sac expulsion with one dose of misoprostol by the first follow-up visit and no additional intervention within 30 days after treatment. RESULTS: Complete expulsion after one dose of misoprostol occurred in 124 of 148 women (83.8%; 95% confidence interval [CI], 76.8 to 89.3) in the mifepristone-pretreatment group and in 100 of 149 women (67.1%; 95% CI, 59.0 to 74.6) in the misoprostol-alone group (relative risk, 1.25; 95% CI, 1.09 to 1.43). Uterine aspiration was performed less frequently in the mifepristone-pretreatment group than in the misoprostol-alone group (8.8% vs. 23.5%; relative risk, 0.37; 95% CI, 0.21 to 0.68). Bleeding that resulted in blood transfusion occurred in 2.0% of the women in the mifepristone-pretreatment group and in 0.7% of the women in the misoprostol-alone group (P=0.31); pelvic infection was diagnosed in 1.3% of the women in each group. CONCLUSIONS: Pretreatment with mifepristone followed by treatment with misoprostol resulted in a higher likelihood of successful management of first-trimester pregnancy loss than treatment with misoprostol alone.

Intrauterine device use, sexually transmitted infections, and fertility: a prospective cohort study.

BACKGROUND: In the 1970s, numerous medical reports, media coverage, and litigation around the Dalkon Shield intrauterine device led to a perception that all intrauterine devices cause upper genital tract infection and infertility. OBJECTIVE: This study aimed to assess the association between intrauterine device use and time to conception. STUDY DESIGN: The Fertility After Contraceptive Termination Study is a multicenter, prospective cohort study of women stopping their contraceptive method to attempt conception. We recruited participants between 2011 and 2017. Participants were a convenience sample of women recruited from academic centers in Philadelphia, PA; Los Angeles, CA; St. Louis, MO; Indianapolis, IN; Aurora, CO; and Salt Lake City, UT. Women were eligible if they stopped their contraceptive method within the past 120 days before enrollment, were between 18 and 35 years of age, had no history of infertility or sterilization, and had at least 6 months of follow-up. Baseline data included demographic and reproductive characteristics, past contraceptive use, nucleic acid amplification testing for sexually transmitted infections, and serology for past infection with Chlamydia trachomatis, Trichomonas vaginalis, and Mycoplasma genitalium. The primary exposure was intrauterine device use (ever); the primary outcome was time to conception. All participants were observed longitudinally for up to 24 months. We used piecewise exponential proportional hazards models with multiple imputation to provide hazard ratios and their respective 95% confidence intervals. RESULTS: Of the 461 participants, mean age was 28.2 years, 178 (38.7%) were Black, 157 (34.1%) were considered as low socioeconomic status, and 275 (59.7%) had a history of intrauterine device use. Without adjusting for any covariates, the median time to conception was shorter for participants who had a history of intrauterine device use (5.1 months) than participants who never used an intrauterine device (7.5 months). After controlling for potential confounders, the association of past intrauterine device use with time to conception was not statistically significant (adjusted hazard ratio, 1.25; 95% confidence interval, 0.99-1.58). In our multivariable model, age, nulligravidity, Black race, low socioeconomic status, and past Mycoplasma genitalium infection were associated with longer times to conception (hazard ratio, 0.76; 95% confidence interval, 0.58-0.99). Conception by 12 months was lower in participants with past Mycoplasma genitalium infection (68% vs 80% without past infection; P=.019). CONCLUSION: We found no impairment of fertility with ever use of an intrauterine device. Serologic evidence of past Mycoplasma genitalium infection was associated with longer times to conception and higher rates of infertility. Mycoplasma genitalium infection is a potential modifiable cause of infertility.

Management of early pregnancy loss with mifepristone and misoprostol: clinical predictors of treatment success from a randomized trial.

BACKGROUND: Early pregnancy loss is a common event in the first trimester, occurring in 15%-20% of confirmed pregnancies. A common evidence-based medical regimen for early pregnancy loss uses misoprostol, a prostaglandin E1 analog, with a dosage of 800 µg, self-administered vaginally. The clinical utility of this regimen is limited by suboptimal effectiveness in patients with a closed cervical os, with 29% of patients experiencing early pregnancy loss requiring a second dose after 3 days and 16% of patients eventually requiring a uterine aspiration procedure. OBJECTIVE: This study aimed to evaluate clinical predictors associated with treatment success in patients receiving medical management with mifepristone-misoprostol or misoprostol alone for early pregnancy loss. STUDY DESIGN: We performed a planned secondary analysis of a randomized trial comparing mifepristone-misoprostol with misoprostol alone for management of early pregnancy loss. The published prediction model for treatment success of single-dose misoprostol administered vaginally included the following variables: active bleeding, type of early pregnancy loss (anembryonic pregnancy or embryonic and/or fetal demise), parity, gestational age, and treatment site; previous significant predictors were vaginal bleeding within the past 24 hours and parity of 0 or 1 vs >1. To determine if these characteristics predicted differential proportions of patients with treatment success or failure, we performed bivariate analyses; given the small proportion of treatment failures in the combined treatment arm, both arms were combined for analysis. Thereafter, we performed a logistic regression analysis to assess the effect of these predictors collectively in each of the 2 treatment groups separately as well as in the full cohort as a proxy for the combined treatment arm. Finally, by using receiver operating characteristic curves, we tested the ability of these predictors in association with misoprostol treatment success to discriminate between treatment success and treatment failure. To quantify the ability of the score to discriminate between treatment success and treatment failure in each treatment arm as well as in the entire cohort, we calculated the area under the curve. Using multivariable logistic regression, we then assessed our study population for other predictors of treatment success in both treatment groups, with and without mifepristone pretreatment. RESULTS: Overall, 297 evaluable participants were included in the primary study, with 148 in the mifepristone-misoprostol combined treatment group and 149 in the misoprostol-alone treatment group. Among patients who had vaginal bleeding at the time of treatment, 15 of 17 (88%) in the mifepristone-misoprostol combined treatment group and 12 of 17 (71%) in the misoprostol-alone treatment group experienced expulsion of pregnancy tissue. Among patients with a parity of 0 or 1, 94 of 108 (87%) in the mifepristone-misoprostol treatment group and 66 of 95 (69%) in the misoprostol-alone treatment group experienced expulsion of pregnancy tissue. These clinical characteristics did not predict treatment success in the combined cohort alone (area under the curve=0.56; 95% confidence interval, 0.48-0.64). No other baseline clinical factors predicted treatment success in the misoprostol-alone treatment arm or mifepristone pretreatment arm. In the full cohort, the significant predictors of treatment success were pretreatment with mifepristone (adjusted odds ratio=2.51; 95% confidence interval, 1.43-4.43) and smoking (adjusted odds ratio=2.15; 95% confidence interval, 1.03-4.49). CONCLUSION: No baseline clinical factors predicted treatment success in women receiving medical management with misoprostol for early pregnancy loss. Adding mifepristone to the medical management regimen of early pregnancy loss improved treatment success; thus, mifepristone treatment should be considered for management of early pregnancy loss regardless of baseline clinical factors.

Bleeding changes after levonorgestrel 52-mg intrauterine system insertion for contraception in women with self-reported heavy menstrual bleeding.

BACKGROUND: The levonorgestrel 52-mg intrauterine system has proven efficacy for heavy menstrual bleeding treatment in clinical trials, but few data exist to demonstrate how rapidly the effects occur and the effects in women with self-reported heavy bleeding, as seen commonly in clinical practice. OBJECTIVE: Evaluate changes in bleeding patterns in women with self-reported heavy menstrual bleeding before levonorgestrel 52-mg intrauterine system insertion. STUDY DESIGN: A total of 1714 women aged 16-45 years old received a levonorgestrel 52-mg intrauterine system in a multicenter trial evaluating contraceptive efficacy and safety for up to 10 years. At screening, participants described their baseline menstrual bleeding patterns for the previous 3 months. Participants completed daily diaries with subjective evaluation of bleeding information for the first 2 years. For this analysis, we included women with at least 1 complete 28-day cycle of intrauterine system use and excluded women using a hormonal or copper intrauterine contraception in the month prior to study enrollment. We evaluated changes in menstrual bleeding and discontinuation for bleeding complaints per 28-day cycle over 26 cycles (2 years) in women who self-reported their baseline pattern as heavy. We also compared rates of amenorrhea, defined as no bleeding or spotting, within the entire study population in women with subjective heavy menstrual bleeding at baseline compared with those who did not complain of heavy menstrual bleeding. RESULTS: Of the 1513 women in this analysis, 150 (9.9%) reported baseline heavy menstrual bleeding. The majority of women reported no longer experiencing heavy menstrual bleeding by the end of cycle 1 (112/150, 74.7%) with even greater rates by cycle 2 (124/148, 83.8%). At the end of cycles 6, 13, and 26, 129 of 140 (92.1%; 95% confidence interval, 87.7%-96.6%), 114 of 123 (92.7%; 95% confidence interval, 88.1%-97.3%), and 100 of 103 (97.1%; 95% confidence interval, 93.8%-100%) women reported no heavy menstrual bleeding, respectively. After cycles 13 and 26, 63 of 123 (51.2%; 95% confidence interval, 42.4%-60.1%) and 66 of 103 (64.1%; 95% confidence interval, 54.8%-73.3%), respectively, reported their bleeding as amenorrhea or spotting only. A lower proportion of women with baseline self-reported heavy menstrual bleeding reported amenorrhea as compared with women in the overall study cohort without heavy menstrual bleeding at the end of 6 cycles (319 [25.5%] vs 21 [15.0%], P=.005) and 13 cycles (382 [34.4%] vs 26 [21.1%], P=.003); differences were not significant after 19 cycles (367 [37.2%] vs 36 [31.0%], P=.022) and 26 cycles (383 [43.5%] vs 38 [36.9%], P=.21). Only 4 (2.7%) women with baseline heavy menstrual bleeding discontinued for bleeding complaints (2 for heavy menstrual bleeding and 2 for irregular bleeding), all within the first year. CONCLUSION: Most women who self-report heavy menstrual bleeding experience significant improvement quickly after levonorgestrel 52-mg intrauterine system insertion. Discontinuation for bleeding complaints among women with baseline heavy menstrual bleeding is very low.

Postpartum contraceptive counseling for first-time adolescent mothers: a randomized controlled trial.

PURPOSE: Rapid repeat pregnancy is common among adolescent mothers and is associated with increased risks of adverse perinatal and maternal outcomes. Increasing contraceptive uptake among postpartum adolescents may decrease these outcomes through pregnancy prevention. This randomized controlled trial of 100 postpartum adolescent women assessed the effect of a standardized immediate postpartum contraceptive counseling intervention emphasizing healthy birth spacing and the use of long-acting reversible contraceptives (LARC). METHODS: After a baseline survey about reproductive health and pregnancy intentions, all subjects received routine postpartum contraceptive counseling. The intervention group also received the standardized counseling intervention. All participants had access to immediate postpartum contraceptive implant initiation or to intrauterine device (IUD) insertion at postpartum follow-up. Contraceptive use and repeat pregnancy were assessed quarterly for 12 months. Differences in repeat pregnancy, as well as contraceptive initiation, continuation, and satisfaction were analyzed. RESULTS: There was no difference in repeat pregnancy or contraceptive initiation, continuation or satisfaction between the study groups. However, regardless of group assignment, all subjects who desired the contraceptive implant used the method, compared to 15% of subjects who desired the IUD (p < 0.001). Three pregnancies occurred among subjects who desired the IUD versus none amongst subjects who desired the implant (p = 0.10). CONCLUSIONS: This standardized postpartum contraceptive counseling intervention did not affect teens' repeat pregnancies or contraceptive use. However, immediate postpartum availability of the contraceptive implant was associated with increased utilization of this method when compared to the IUD. Future postpartum contraceptive efforts should investigate procedures to improve teens' access to postpartum contraception. CLINICALTRIALS. GOV IDENTIFIER: NCT01814930.

Gestational hormone trajectories and early pregnancy failure: a reassessment.

BACKGROUND: Studies have commonly assessed the endocrinolgical status of women once miscarriage is threatened or suspected; few studies have explored the antecedent hormonal environment or used a longitudinal strategy. Using refined statistical techniques, we sought to re-evaluate whether gestational hormone trajectories in early pregnancy can identify future miscarriage in asymptomatic pregnancies. METHODS: This prospective cohort study followed 105 women over-conception; 72 had normal term pregnancy outcomes while 33 experienced early pregnancy failure between 35 and 115 days of gestation. Participants attended a pre-conception and antenatal clinic at Newcastle University, United Kingdom (UK). Evaluation methods included ultrasound, clinical assessments of pregnancy progress and serial measurements of gestational hormones by radioimmunoassays. Linear mixed-effects regression analysis examined hormone relationships with pregnancy outcomes. RESULTS: Detailed longitudinal illustration of gestational hormones, antecedent to miscarriage indications, revealed early pathophysiological trends. In particular, oestradiol showed as marked a deviation from normal as progesterone before miscarriage was evident, reflecting a deficiency in the ovarian response to rising human chorionic gonadotrophin (hCG) levels. Regression analysis provided equations for gestational hormone slopes that significantly differentiated asymptomatic women with subsequent early pregnancy failure, compared to women with normal term pregnancies. Both progesterone and oestradiol displayed negative mean slopes in pregnancies destined for failure; in this group, both human placental lactogen (hPL) and hCG revealed mean positive trajectories that imitated normal pregnancies but at slower rates of increase. CONCLUSIONS: Oestradiol, progesterone and hCG trajectories, from 50 days of gestation, have good potential for revealing pathophysiology and for identifying which asymptomatic pregnancies are destined for subsequent failure. In asymptomatic patients where there is concern about viability and ultrasound diagnosis is ambiguous, a combined hormonal profile could contribute to guiding patient care decisions.

Six-month expulsion of postplacental copper intrauterine devices placed after vaginal delivery.

BACKGROUND: Immediate placement of an intrauterine device after vaginal delivery is safe and convenient, but longitudinal data describing clinical outcomes have been limited. OBJECTIVE: We sought to determine the proportion of TCu380A (copper) intrauterine devices expelled, partially expelled, malpositioned, and retained, as well as contraceptive use by 6 months postpartum, and determine risk factors for expulsion and partial expulsion. STUDY DESIGN: In this prospective, observational study, women who received a postplacental TCu380A intrauterine device at vaginal delivery were enrolled postpartum. Participants returned for clinical follow-up at 6 weeks, and for a research visit with a pelvic exam and ultrasound at 6 months. We recorded intrauterine device outcomes and 6-month contraceptive use. Partial expulsion was defined as an intrauterine device protruding from the external cervical os, or a transvaginal ultrasound showing the distal end of the intrauterine device below the internal os of the cervix. Multinomial logistic regression models identified risk factors associated with expulsion and partial expulsion by 6 months. The area under the receiver operating characteristics curve was used to assess the ability of a string check to predict the correct placement of a postplacental intrauterine device. The primary outcome was the proportion of intrauterine devices expelled at 6 months. RESULTS: We enrolled 200 women. Of 162 participants with follow-up data at 6 months, 13 (8.0%; 95% confidence interval, 4.7-13.4%) experienced complete expulsion and 26 (16.0%; 95% confidence interval, 11.1-22.6%) partial expulsion. Of 25 malpositioned intrauterine devices (15.4%; 95% confidence interval, 10.2-21.9%), 14 were not at the fundus (8.6%; 95% confidence interval, 5.2-14.1%) and 11 were rotated within the uterus (6.8%; 95% confidence interval, 3.8-11.9%). Multinomial logistic regression modeling indicated that higher parity (odds ratio, 2.05; 95% confidence interval, 1.21-3.50; P = .008) was associated with expulsion. Provider specialty (obstetrics vs family medicine; odds ratio, 5.31; 95% confidence interval, 1.20-23.59; P = .03) and gestational weight gain (normal vs excess; odds ratio, 9.12; 95% confidence interval, 1.90-43.82; P = .004) were associated with partial expulsion. Long-acting reversible contraceptive method use at 6 months was 80.9% (95% confidence interval, 74.0-86.6%). At 6 weeks postpartum, 35 of 149 (23.5%; 95% confidence interval, 16.9-31.1%) participants had no intrauterine device strings visible. Sensitivity of a string check to detect an incorrectly positioned intrauterine device was 36.2%, and specificity of the string check to predict a correctly positioned intrauterine device was 84.5%. This corresponds to an area under the receiver operating characteristics curve of 0.5. CONCLUSION: This prospective assessment of postplacental TCu380A intrauterine device placement, with ultrasound to confirm device position, finds a complete intrauterine device expulsion proportion of 8.0% at 6 months. The association of increasing parity with expulsion is consistent with prior research. The clinical significance of covariates associated with partial expulsion (provider specialty and gestational weight gain) is unclear. Due to the observational study design, any associations cannot imply causality. The proportion of partially expelled and malpositioned intrauterine devices was high, and the area under the receiver operating characteristics curve of 0.5 indicates that a string check is a poor test for assessing device position. Women considering a postplacental intrauterine device should be counseled about the risk of position abnormalities, as well as the possibility of nonvisible strings, which may complicate clinical follow-up. The clinical significance of intrauterine device position abnormalities is unknown; future research should evaluate the influence of malposition and partial expulsion on contraceptive effectiveness and side effects.

Bleeding patterns for the Liletta® levonorgestrel 52 mg intrauterine system.

PURPOSE: Evaluate bleeding patterns for the Liletta® levonorgestrel 52 mg intrauterine system (IUS) using the World Health Organization Belsey definitions. MATERIAL AND METHODS: This prospective multicenter trial evaluates the efficacy and safety of Liletta® (Clinicaltrials.gov NCT00995150). We evaluated bleeding patterns for 1700 nulliparous and multiparous women using a daily diary completed by participants for the first 2 years and by questionnaire every 3 months thereafter. We assessed amenorrhea rates over 3 years and the proportion of subjects with infrequent, frequent, prolonged and irregular bleeding per 90-day reference period over 2 years for the entire study population as well as comparing nulliparous and parous women and obese and non-obese women. RESULTS: Amenorrhea rates at 1 and 3 years in levonorgestrel 52 mg IUS users were 19 and 37%, respectively. The infrequent bleeding rate increased from 14% in the first 90 days to 30% at the end of Year 1, and was maintained at the same rate through Year 2. Frequent, prolonged and irregular bleeding declined to low levels by the end of the first year. Discontinuation for bleeding-related complaints occurred in 35 (2.1%, 95% CI 1.3-2.7%) women during the first 36 months; only one subject discontinued for amenorrhea (in Year 2). Outcomes did not vary for nulliparous versus parous or obese versus non-obese women. CONCLUSIONS: Among Liletta users, amenorrhea and infrequent bleeding become more prevalent over time and amenorrhea rates continue to increase after the first year of use. Bleeding patterns do not differ significantly by parity or by obesity-status. Discontinuation for bleeding concerns is uncommon with this product.

Doulas for surgical management of miscarriage and abortion: a randomized controlled trial.

BACKGROUND: Women undergoing office-based surgical management of a failed or undesired pregnancy often report fear of pain and anxiety pertaining to the procedure. Doulas are trained to specifically address women's physical and emotional needs in obstetric care, and recently have extended their practice to support women through all pregnancy outcomes. OBJECTIVE: We sought to evaluate the impact of doulas on patients' physical and emotional responses to surgical management of a first-trimester failed or undesired pregnancy under local anesthesia. STUDY DESIGN: In this nonblinded, randomized trial, women received doula support or routine care during office uterine aspiration for failed or unwanted pregnancies in the first trimester. The primary outcome was pain measured on a 100-mm visual analog scale. Secondary outcomes included satisfaction, emotional state, sense of personal empowerment, and ability to cope immediately and 1 month after the procedure, as well as medical assistants' assessment of the doula's utility. A sample size of 35 per group (N = 70) was planned to detect a 20% difference in pain score. RESULTS: From April 2014 through January 2015, 129 women were screened and 70 were randomized. The 2 study groups were similar on all baseline characteristics. The primary outcome was not different between the doula and control groups (pain score 70.7 ± 24.5 mm vs 59.7 ± 32.5 mm, P = .11, respectively), even after controlling for procedure indication (P = .20). While 97% of women who received doula support reported this helped with their experience, there was no statistically significant difference in satisfaction, emotional response, sense of empowerment, or perceived ability to cope between the 2 groups of women immediately following or 1 month after the procedure. Of all study participants, 72% reported that it was important to have someone with them during the procedure, but that the support person did not have to be a doula. CONCLUSION: Doula support during office uterine aspiration for failed or undesired pregnancies is well received and desired by women undergoing this procedure despite no significant effect on physical comfort or emotional responses related to the procedure. This may suggest an unmet psychosocial need for procedure-related support among such women.

Validity of self-reported history of Chlamydia trachomatis infection.

BACKGROUND: Chlamydia trachomatis infection is common and largely asymptomatic in women. If untreated, it can lead to sequelae such as pelvic inflammatory disease and infertility. It is unknown whether a patient's self-reported history of Chlamydia trachomatis infection is a valid marker of past infection. OBJECTIVE: Our objective was to evaluate the validity of women's self-reported history of Chlamydia trachomatis infection compared with Chlamydia trachomatis serology, a marker for previous infection. STUDY DESIGN: We analyzed data from the Fertility After Contraception Termination study. We compared participants' survey responses with the question, "Have you ever been told by a health care provider that you had Chlamydia?" to serological test results indicating the presence or absence of antibodies to Chlamydia trachomatis as assessed by a microimmunofluorescence assay. Prevalence of past infection, sensitivity, specificity, predictive values, and likelihood ratios were calculated. The Cohen's kappa statistic was computed to assess agreement between self-report and serology. RESULTS: Among 409 participants, 108 (26%) reported having a history of Chlamydia trachomatis infection, whereas 146 (36%) had positive serological test results. Relative to positive microimmunofluorescence assay, the sensitivity and specificity of self-reported history of Chlamydia trachomatis infection were 52.1% (95% confidence interval, 43.6-60.4%) and 87.8% (95% confidence interval, 83.3-91.5%), respectively. The positive predictive value of the self-report was 70.4% (95% confidence interval, 60.8-78.8%), and the negative predictive value was 76.7% (95% confidence interval, 71.6-81.4%). The likelihood ratio was found to be 4.28. Agreement between self-report and serology was found to be moderate (kappa = 0.42, P < .001). CONCLUSION: Self-reported history of Chlamydia trachomatis infection commonly yields false-negative and false-positive results. When definitive status of past Chlamydia trachomatis infection is needed, serology should be obtained.

Unintended Pregnancy, Induced Abortion, and Mental Health.

PURPOSE OF REVIEW: The early medical literature on mental health outcomes following abortion is fraught with methodological flaws that can improperly influence clinical practice. Our goal is to review the current medical literature on depression and other mental health outcomes for women obtaining abortions. RECENT FINDINGS: The Turnaway Study prospectively enrolled 956 women seeking abortion in the USA and followed their mental health outcomes for 5 years. The control group was comprised of women denied abortions based on gestational age limits, thereby circumventing the major methodological flaw that had plagued earlier studies on the topic. Rates of depression are not significantly different between women obtaining abortion and those denied abortion. Rates of anxiety are initially higher in women denied abortion care. Counseling on decision-making for women with unintended pregnancies should reflect these findings.

Postpartum adolescents' contraceptive counselling preferences.

OBJECTIVES: The optimal approach for provision and timing of postpartum contraceptive counselling for adolescents has not been established. To reduce repeat pregnancies from current USA levels of nearly 20%, a better understanding is needed of postpartum adolescent females' preferences regarding contraceptive counselling and delivery. METHODS: Semi-structured interviews with 30 USA postpartum teens (97% Black) explored pregnancy prevention and contraceptive counselling. Transcripts were independently coded by two researchers and inter-rater reliability calculated using Kappa coefficients. With a standard content analysis approach, common themes were identified, coded and summarized. RESULTS: Findings indicated pregnancy prevention was important - two thirds of subjects reported becoming pregnant 'too soon', almost all did not desire another child for at least 6 years and most indicated that pregnancy prevention was either 'very' or 'extremely' important right now. The subjects described doctors and their prenatal clinic as their most accurate sources of contraception information, but stated that doctors and parents were the most helpful sources. All were comfortable discussing contraception with providers and had a desire for shared decision making. While many had received written materials, most preferred in-person contraceptive counselling. Optimally, participants suggested that contraceptive counselling would be provided by a physician, begin antepartum and almost all preferred to leave the hospital with their chosen method of contraception. CONCLUSIONS: Pregnancy prevention is important for postpartum adolescents as most desired to delay future childbearing. In-person contraceptive counselling should begin in the antepartum period and include provision of contraception prior to discharge.

A self-assessment efficacy tool for spermicide contraceptive users.

BACKGROUND: Easily accessible contraceptive methods, such as chemical and barrier methods, are used currently by approximately 1 in 6 women who use contraception in the United States. Even in the face of suboptimal effectiveness, coitally dependent methods likely will always have a role in fertility management. Because most contraceptive efficacy stratifications use population-based data, for women to make informed decisions about the individual fit of a contraceptive method, better evidence-based, user-friendly tools are needed. OBJECTIVES: Spermicides are a readily available, over-the counter, woman-controlled contraceptive method, but their effectiveness is user-dependent. Patient-decision aids for spermicides and other barrier methods are not well-developed, and overall failure rates could be improved by aids that account for individual characteristics. We sought to derive a prediction rule for successful use of spermicides for pregnancy prevention and to convert those data to a point-of-care instrument that women can use when they are considering spermicide use during contraceptive decision-making. STUDY DESIGN: We pooled local data from 3 randomized clinical trials that were published in 2004, 2007, and 2010 that tested spermicide efficacy. We constructed a prediction rule for unintended pregnancy using bootstrap validation and developed a scoring system. RESULTS: Data from 621 women showed a mean age of 29 years; 49% of the women were African American, and 43% were white. The overall pregnancy rate was 10.3% (95% confidence interval, 7.9-12.7) over 6 months. In adjusted logistic regression, age >35 years was protective against pregnancy (odds ratio, 0.19; 95% confidence interval, 0.06-0.58; P = .003), and multigravidity was associated with high failure rates (odds ratio, 7.24; 95% confidence interval, 3.04-17.3; P < .001). These risk factors (together with frequency of unprotected sex) were used in a model that maximized sensitivity for pregnancy prediction to compute the predicted probability of unintended pregnancy for each woman. This model was 97% accurate in predicting women who had a <5% pregnancy risk while using spermicides. CONCLUSION: Using prospectively collected data, we built a simple risk calculator for contraceptive failure that women can consult when considering spermicide use. This instrument could support patient-centered contraceptive decision-making.
