Urinary Phthalate Metabolite Concentrations and Reproductive Outcomes among Women Undergoing in Vitro Fertilization: Results from the EARTH Study.

Background: Evidence from both animal and human studies suggests that exposure to phthalates may be associated with adverse female reproductive outcomes. Objective: We evaluated the associations between urinary concentrations of phthalate metabolites and outcomes of assisted reproductive technologies (ART). Methods: This analysis included 256 women enrolled in the Environment and Reproductive Health (EARTH) prospective cohort study (2004–2012) who provided one to two urine samples per cycle before oocyte retrieval. We measured 11 urinary phthalate metabolites [mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), mono(2-ethyl-5-oxohexyl) phthalate (MEOHP), mono(2-ethyl-5-carboxypentyl) phthalate (MECPP), mono-isobutyl phthalate (MiBP), mono-n-butyl phthalate (MBP), monobenzyl phthalate (MBzP), monoethyl phthalate (MEP), monocarboxyisooctyl phthalate (MCOP), monocarboxyisononyl phthalate (MCNP), and mono(3-carboxypropyl) phthalate (MCPP)]. We used generalized linear mixed models to evaluate the association of urinary phthalate metabolites with in vitro fertilization (IVF) outcomes, accounting for multiple IVF cycles per woman. Results: In multivariate models, women in the highest as compared with lowest quartile of MEHP, MEHHP, MEOHP, MECPP, ΣDEHP (MEHP + MEHHP + MEOHP + MECPP), and MCNP had lower oocyte yield. Similarly, the number of mature (MII) oocytes retrieved was lower in the highest versus lowest quartile for these same phthalate metabolites. The adjusted differences (95% CI) in proportion of cycles resulting in clinical pregnancy and live birth between women in the fourth versus first quartile of ΣDEHP were –0.19 (–0.29, –0.08) and –0.19 (–0.28, –0.08), respectively, and there was also a lower proportion of cycles resulting in clinical pregnancy and live birth for individual DEHP metabolites. Conclusions: Urinary concentrations of DEHP metabolites were inversely associated with oocyte yield, clinical pregnancy, and live birth following ART.

Contraceptive Counseling for Women Who Undergo Bariatric Surgery

BACKGROUND Women are counseled to avoid becoming pregnant for 12-24 months after bariatric surgery. The aim of this study was to assess contraceptive counseling and use in women who undergo bariatric surgery. METHODS A self-administered survey was completed by women aged 18-45 years at a postoperative clinic visit >2 months after bariatric surgery at an urban teaching hospital. RESULTS Of the 69 respondents, 94.2% knew to avoid pregnancy for at least 12 months after surgery. However, 16.3% did not use any contraception 2-12 months after surgery. The most common contraceptive methods used were condoms (30.6%) and oral contraceptives (16.3%). Longer-acting reversible contraceptives were used less frequently; for example, only 4% of women used intrauterine devices. Only 21.2% of respondents were referred to an obstetrician/gynecologist for contraceptive counseling. CONCLUSIONS Many women who undergo bariatric surgery are not using very effective contraceptive methods or any contraception. There is a clear opportunity to improve counseling and increase use of more effective contraception in this population.

Assessment of long-term knowledge retention following single-day simulation training for uncommon but critical obstetrical events

Objective: The objectives were to determine (i) whether simulation training results in short-term and long-term improvement in the management of uncommon but critical obstetrical events and (ii) to determine whether there was additional benefit from annual exposure to the workshop. Methods: Physicians completed a pretest to measure knowledge and confidence in the management of eclampsia, shoulder dystocia, postpartum hemorrhage and vacuum-assisted vaginal delivery. They then attended a simulation workshop and immediately completed a posttest. Residents completed the same posttests 4 and 12 months later, and attending physicians completed the posttest at 12 months. Physicians participated in the same simulation workshop 1 year later and then completed a final posttest. Scores were compared using paired t-tests. Results: Physicians demonstrated improved knowledge and comfort immediately after simulation. Residents maintained this improvement at 1 year. Attending physicians remained more comfortable managing these scenarios up to 1 year later; however, knowledge retention diminished with time. Repeating the simulation after 1 year brought additional improvement to physicians. Conclusion: Simulation training can result in short-term and contribute to long-term improvement in objective measures of knowledge and comfort level in managing uncommon but critical obstetrical events. Repeat exposure to simulation training after 1 year can yield additional benefits.

Fundamentals of laparoscopic surgery: a surgical skills assessment tool in gynecology.

This analysis suggests that the fundamentals of laparoscopic surgery skills test may be a valuable assessment tool for gynecology residents; however, the cognitive test may need further adaptation for application to gynecologists.

Evaluation of a rapid, real-time intrapartum group B streptococcus assay.

OBJECTIVE We sought to evaluate an intrapartum nucleic acid amplification test (NAAT) for group B streptococcus (GBS). STUDY DESIGN This was a prospective cohort study of 559 women comparing intrapartum GBS culture with antepartum culture and intrapartum NAAT. RESULTS GBS prevalence was 19.5% by antepartum culture and 23.8% by intrapartum culture. Compared with intrapartum culture, antepartum culture had 69.2% sensitivity (60.6-76.9%) and 96.0% specificity (93.7-97.7%). The NAAT demonstrated sensitivity of 90.8% (84.6-95.2%), specificity of 97.6% (95.6-98.8%), and predictive values >92%. The incidence of discordant cultures was 10.4%. Of the women with negative antepartum and positive intrapartum cultures, only 1 (2.4%) received intrapartum antibiotics. Compared with white women, black (P = .02) and Hispanic (P = .02) women were more likely to have discordant cultures. CONCLUSION This intrapartum NAAT has excellent characteristics. It may be superior to antepartum culture for detecting intrapartum GBS-allowing more accurate management of laboring mothers and reducing neonatal GBS sepsis.

The cumulative probability of liveborn multiples after in vitro fertilization: a cohort study of more than 10,000 women

OBJECTIVE To estimate the cumulative probability of liveborn multiples after IVF to improve patient counseling regarding this significant morbidity. DESIGN Retrospective cohort study. SETTING Large academic-affiliated infertility practice. PATIENT(S) A total of 10,169 women were followed from their first fresh, nondonor IVF cycle through up to six fresh and frozen IVF cycles from 2000-2010. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Delivery of a liveborn infant(s). RESULT(S) After three IVF cycles the cumulative live birth rate (CLBR) was 53.2%. The singleton, twin, and triplet CLBRs were 38.0%, 14.5%, and 0.7%. After six IVF cycles the CLBR was 73.8%, with 52.8%, 19.8%, 1.3% for singletons, twins, and triplets. Of the 5,433 live births, 71.4% were singletons, 27.1% were twins, and 1.5% were triplets. Women more than 39 years had the lowest incidence of liveborn multiples with CLBRs of 5.2% after three cycles and 9.5% after six cycles. The twin CLBR doubled from cycles 1 through 3 with the rate of increase slowing from cycles 3 through 6. Although very low in absolute terms, the triplet CLBR also doubled from cycles 1 through 3 and doubled again from cycles 3 through 6. Of the 1,970 pregnancies that began as multifetal on ultrasound, 77.4% resulted in liveborn multiples. CONCLUSION(S) Providers should be aware of the cumulative probability of liveborn multiples to effectively counsel patients on this important issue. With nearly three-quarters of all women having live birth after up to six IVF cycles, it is encouraging to report a low incidence of liveborn multiples.

In Vitro Fertilization Is Successful in Women With Ulcerative Colitis and Ileal Pouch Anal Anastomosis.

Background:Women with ulcerative colitis (UC), who require ileal pouch anal anastomosis (IPAA), have up to a threefold increased incidence of infertility. To better counsel patients who require colectomy, we examined the success rates of in vitro fertilization (IVF) among women who have undergone IPAA.Methods:This was a retrospective cohort study conducted at the Brigham and Women’s Hospital and Beth Israel Deaconess Medical Center. Female patients with UC were identified via ICD-9 codes and cross-referenced with those presenting for IVF from 1998 through 2011. UC patients with IPAA were compared with the following two unexposed groups that underwent IVF: (1) patients with UC, who had not undergone IPAA, and (2) patients without inflammatory bowel disease (IBD). The primary outcome was the cumulative live birth rate. Secondary outcomes included number of oocytes retrieved, proportion of patients who underwent embryo transfer, pregnancy rate, and live birth rate at first cycle.Results:There were 22 patients with UC and IPAA, 49 patients with UC and without IPAA, and 470 patients without IBD. The cumulative live birth rate after six cycles in the UC and IPAA groups was 64% (95% confidence interval (CI): 44–83%). This rate did not differ from the cumulative live birth rate in the UC without IPAA group (71%, 95% CI: 59–83%; P=0.63) or the group without IBD (53%, 95% CI: 48–57%; P=0.57).Conclusions:This study demonstrates that in our cohort, women who undergo IPAA achieve live births following IVF at comparable rates to women with UC without IPAA and to women without IBD.

Risk of ectopic pregnancy following day-5 embryo transfer compared with day-3 transfer

The incidence of ectopic pregnancy after IVF is increased approximately 2.5-5-fold compared with natural conceptions; however, the aetiology for this increased risk remains unclear. One proposed practice change to decrease the incidence of ectopic pregnancy is blastocyst embryo transfer on day 5 rather than cleavage-stage embryo transfer on day 3. A retrospective cohort study was conducted to compare the risk of ectopic pregnancy following fresh day-5 embryo transfer with day-3 embryo transfer among women who underwent IVF and achieved pregnancy from 1998 to 2011. There were 13,654 eligible pregnancies; 277 were ectopic. The incidence of ectopic pregnancy was 2.1% among day-3 pregnancies and 1.6% among day-5 pregnancies. The adjusted risk ratio for ectopic pregnancy from day-5 compared with day-3 transfer was 0.71 (95% confidence interval 0.46-1.10). Although this analysis included 13,654 cycles, with a two-sided significance level of 0.05, it had only 21.9% power to detect a difference between the low incidence of ectopic pregnancy among both day-3 and day-5 transfers. In conclusion, this study was not able to demonstrate a difference in the risk of ectopic pregnancy among day-3 compared with day-5 transfers.

Subspecialty and Gender of Obstetrics and Gynecology Faculty in Department-Based Leadership Roles

OBJECTIVE: To characterize the cohort who may become senior leaders in obstetrics and gynecology by examining the gender and subspecialty of faculty in academic department administrative and educational leadership roles. METHODS: This is an observational study conducted through web sites of U.S. obstetrics and gynecology residency programs accredited in 2012–2013. RESULTS: In obstetrics and gynecology departmental administrative leadership roles, women comprised 20.4% of chairs, 36.1% of vice chairs, and 29.6% of division directors. Among educational leaders, women comprised 31.9% of fellowship directors, 47.3% of residency directors, and 66.1% of medical student clerkship directors. Chairs were most likely to be maternal–fetal medicine faculty (38.2%) followed by specialists in general obstetrics and gynecology (21.8%), reproductive endocrinologists (15.6%), and gynecologic oncologists (14.7%). Among chairs, 32.9% are male maternal–fetal medicine specialists. Family planning had the highest representation of women (80.0%) among division directors, whereas reproductive endocrinology and infertility had the lowest (15.8%). The largest proportion of women chairs, vice chairs, residency program directors, and medical student clerkship directors were specialists in general obstetrics and gynecology. CONCLUSION: Women remained underrepresented in the departmental leadership roles of chair, vice chair, division director, and fellowship director. Representation of women was closer to parity among residency program directors, in which women held just under half of positions. Nearly one in three department chairs was a male maternal–fetal medicine specialist. Compared with subspecialist leaders, specialist leaders in general obstetrics and gynecology were more likely to be women. LEVEL OF EVIDENCE: II

Association of body mass index with hip and thigh pain following transobturator midurethral sling placement

OBJECTIVE We sought to investigate the incidence of hip and proximal lower extremity pain following transobturator midurethral sling and evaluate the association between pain and body mass index (BMI). STUDY DESIGN This was a retrospective cohort study of all transobturator midurethral sling procedures from July 2008 through June 2009. The primary outcome was postoperative hip or proximal lower extremity pain. RESULTS Four urogynecologists performed 226 procedures. The incidence of postoperative hip or proximal lower extremity pain was 15.5%. Women of normal BMI had a higher risk of developing pain than obese women (risk ratio, 2.51; 95% confidence interval, 1.01-6.22). While not statistically significant, overweight women were twice as likely as obese women to develop the primary outcome (risk ratio, 1.99; 95% confidence interval, 0.79-4.99). CONCLUSION Women of normal BMI have an increased risk of hip and proximal lower extremity pain following transobturator midurethral sling compared with obese women.
