RESUMEN

PURPOSE: Our objective was to determine if a change in serum P4 from day of transfer (defined as day 19) to day 28 could predict live birth outcome in patients undergoing IVF. METHODS: This study was a retrospective analysis of fresh IVF cycles from 2010 to 2013 at a single center. Primary outcomes include raw and percent change in serum P4, live birth rate, missed abortion, and biochemical pregnancies. RESULTS: Our results showed an association between live birth rate and percent change in P4. Patients with a 10% or greater drop in serum P4 from day 19 to day 28 had a lower live birth rate, at 26 versus 63%. Interestingly, both groups had "normal" serum P4 levels on day 19, but patients with a 10% or greater drop had lower P4 levels than their counterparts. There was no association between percent P4 change and spontaneous abortion or biochemical pregnancy. CONCLUSIONS: This is the first study to show that percent drop in serum P4 from day of transfer to day 28 is associated with decreased rates of live birth and ongoing pregnancy in fresh IVF cycles, even despite "high or normal" P4 levels on day of transfer.

RESUMEN

PURPOSE: The purpose of our study was to determine if progesterone (P4) values on day of trigger affect certain cycle outcome parameters, ploidy status of embryos, as well as pregnancy outcomes in the subsequent first frozen embryo transfer cycle. METHODS: Two hundred thirty-eight patients undergoing pre-gestational screening and freeze all protocol at our fertility center from 2013 to 2014 were included. Excluded patients were those whom had cancelled cycles prior to egg retrieval as well as cycles utilizing donor eggs. Once patients were identified as eligible for this study, frozen serum from the day of trigger was identified and analyzed using the Siemens Immulite 2000. Number of eggs retrieved, number of available embryos for biopsy, and number of euploid/aneuploid embryos were analyzed. The first frozen embryo transfer cycle was linked to the initial egg retrieval and outcomes including pregnancy rates, and live birth/ongoing pregnancy rates were calculated and analyzed. A discriminatory P4 value of 1.5 ng/ml was set. Group A had P4 values of less than 1.5 ng/ml and group B had P4 values greater than or equal to 1.5 ng/ml. T tests and chi-squared tests were used for statistical analysis. RESULTS: Group A had an average trigger P4 value of 0.87 +/- 0.3 and group B had an average trigger P4 of 2.1 +/- 0.8. Table 1 shows the baseline characteristics of both group A and group B. The only significant difference between the two groups was total gonadotropin dosage (IU) with a p value of 0.02 and estradiol (pg/ml) at trigger, also with a p value of 0.02 (Table 1). Number of eggs retrieved, number of embryos biopsied, number euploid/aneuploid, and non-diagnosis embryos were all non-significant. Chi-square analysis was used to compare pregnancy rates between the two groups after the first frozen embryo transfer cycle. Group A had a pregnancy rate of 72 % and Group B had a pregnancy rate of 66.7 %, which was not significant. Ongoing pregnancy/live birth rates were 65.6 % in group A and 66.67 % in group B, also not significant (Table 2). CONCLUSIONS: P4 values on day of trigger do not affect number of eggs retrieved and number of chromosomally normal embryos available for transfer in a subsequent embryo transfer cycle. Elevated P4 values (≥1.5 ng/ml) also do not affect pregnancy rates or live birth/ongoing pregnancy rates in the first subsequent frozen embryo transfer cycle.

RESUMEN

BACKGROUND: Progesterone (P4) is essential for support of the endometrium and implantation of an embryo in the normal menstrual cycle. In programed frozen embryo transfer cycles using exogenous P4 is necessary, as the endogenous production of P4 requires a functioning corpus luteum that is not present in programed cycles. To date, there is continuing debate about ideal serum estradiol and P4 values in frozen embryo transfer cycles. METHODS: Patients underwent single euploid embryo frozen transfer cycles from 2010 to 2013 at a single large academic center. Patients using donor oocytes and patients with changes in progesterone dose during the cycles in question were excluded. All cycles were programed and intramuscular P4 was used exclusively. Only patients administering the same daily dose of P4 throughout the cycle were included (N = 213 patients). Main outcomes were ongoing pregnancy/live birth rates (OPR/LBR), clinical pregnancy rates (CPR), and spontaneous abortions/biochemical pregnancies. CPR was defined by the presence of a sac on 1st trimester ultrasound. Missed abortions were calculated per pregnancy with a sac. Receiver operator characteristic curves (ROC curves) and chi-squared tests were performed for statistical analysis. RESULTS: Two groups based on day 19 P4 levels were compared (group A, P4 < 20 ng/ml; group B, P4 > 20 ng/ml). OPR/LBRs were 65 vs. 49 %, group A vs. B, p value = 0.02, RR = 1.33 (1.1-1.7). Missed abortion and biochemical rates were higher in group B as opposed to group A, 27 vs. 12 %, p = 0.01, RR = 0.45(0.24-0.86). When P4 was stratified into five groups based on nanogram per milliliter of progesterone on day 19 (10-15, 15-20, 20-30, 30-40, and >40), there was a trend downward in OPR/LBR (70, 62, 52, 50, and 33 %, respectively). There was also an increase in missed abortion/biochemical rates (7, 15, 27, 32, and 20 %, respectively). Multiple logistic regression showed an increase in OPR/LBR when accounting for age, day 2 FSH, weight, number of embryos biopsied, and number of euploid embryos. CONCLUSION: P4 levels >20 ng/ml on the day of transfer (during frozen single euploid embryo transfer cycles) were associated with decreased OPR/LBR.

RESUMEN

BACKGROUND: Thyroid storm is a potentially life-threatening complication of gestational trophoblastic disease (GTD), with varying clinical severity. It should be considered in patients with GTD, abnormal vital signs, and clinical signs of hyperthyroidism. CASE REPORT: A 45-year-old non-English-speaking patient presented to a New York City hospital in November 2011 with an aborting molar pregnancy and severe hemorrhage. Initial presentation was concerning for GTD. Laboratory values were obtained that confirmed the diagnosis of GTD, which was also by thyroid storm and congestive heart failure. This was evidenced by laboratory values of free thyroxine of 4.9 and beta human chorionic gonadotropin of 1,488,021 IU/mL. Dilation and curettage with 16-mm suction catheter was performed until all products of conception were removed and bleeding was controlled. The patient was admitted to the surgical intensive care unit and proceeded to have multi-organ failure, and remained intubated and unresponsive to verbal/visual and tactile stimuli. On postoperative day 13 the patient suddenly became alert and self-extubated, began to communicate verbally, and resolution of her multi-organ failure became evident. The patient was discharged with Gynecologic Oncology follow-up. Why should an emergency care physician be aware of this? This case represents the dangers associated with poor prenatal care and late diagnosis of molar pregnancy. It also represents the need for immediate recognition of the condition and initiation of appropriate medical care. Although this patient's clinical outcome was good, the event could have been prevented had she received reliable medical care.

RESUMEN

PURPOSE: To determine if Aneuploidy Risk Classification Models are predictive of euploidy/aneuploidy amongst IVF facilities. METHODS: We retrospectively applied key time lapse imaging events of embryos (Campbell et al.[5, 6]) to stratify embryos into 3 groups: low, medium and high risk of aneuploidy. The actual ploidy results (from array comparative genomic hybridization) were compared with expectations [5, 6]. Sources of variability in morphokinetic parameters were determined using Analysis of Variance (ANOVA). RESULTS: The model failed to segregate euploid embryos from aneuploid embryos cultured at our facility. Further analysis indicated that the variability of embryos among patients was too great to allow selection of euploid embryos based on simple morphokinetic thresholds. Clinical selection of embryos based on morphokinetics alone is unlikely to identify euploid embryos accurately for transfer or yield higher rates of live delivery. CONCLUSIONS: The use of non-invasive morphokinetics is unlikely to discriminate aneuploid from euploid embryos. Further, it does not approach the accuracy of preimplantation genetic screening with array comparative genomic hybridization.

RESUMEN

Background: Cervical pregnancy is a diagnosis associated with significant morbidity, specifically life-threatening hemorrhage that potentially requires hysterectomy to prevent maternal death. Conservative and fertility-sparing management strategies are poorly described in the literature, and there is no clear standard of care. Case: The patient was a 34-year-old gravida 1, para 0 who had conceived spontaneously after laparoscopic treatment of endometriosis, and was found to have cervical pregnancy. She received both intramuscular and intra-sac methotrexate, with no resolution of the ectopic pregnancy. The pregnancy was removed hysteroscopically. Results: Subsequently, the patient was able to achieve a normal clinical pregnancy with ovulation induction/intrauterine insemination. This pregnancy was carried to term. Conclusions: Although cervical pregnancy is particularly hazardous and potentially fatal, conservative/fertility-sparing management of these pregnancies can be successful. (J GYNECOL SURG 28:369).

RESUMEN

OBJECTIVE: Our objective was to characterize the most frequently cited articles published in obstetrics and gynecology journals during the last 50 years. STUDY DESIGN: We utilized the 2008 edition of Journal Citation Reports and Social Sciences Citation Index database to determine the most frequently cited articles published after 1956. Articles were evaluated for several characteristics, and an unadjusted categorical analysis was performed to compare pre- and post-1980 articles. RESULTS: The 100 most frequently cited articles were published in 11 journals between 1957 and 2004. Most articles were published by US-based authors. Forty-four articles were related to obstetrics and 56 were related to gynecology. The most common study design was observational. There were only 7 randomized controlled trials, and randomized controlled trials were not more common after 1980 (6.3% vs 8.1%; P = .71). CONCLUSION: Most "citation classics" in obstetrics and gynecology are observational studies published in high-impact journals by US-based authors after 1980.

RESUMEN

AIM: To determine whether a follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratio over 3 in the setting of a normal FSH (<12 IU/l) is associated with a higher rate of failed controlled ovarian stimulation cycles. DESIGN: Retrospective cohort. MATERIALS & METHODS: A total of 676 patients were identified; 198 patients had a FSH/LH ratio >3 and 477 patients had a FSH/LH ratio <3. Exclusion criteria included: age >40 years; estradiol (E2) prime protocols; E2 at start >70 pg/ml; and FSH at start >12 IU/l. The main outcome measure was cycle cancellation. RESULTS: An elevated FSH/LH ratio >3 was more likely to result in the individual's cycle cancelled (15 vs 5.24%; p = 0.0001). The total gonadotropin dosage was greater in the higher ratio versus lower ratio group (2636 vs 2242 IU; significant). Peak E2 was significantly lower in the FSH/LH >3 group (peak E2: 1635 vs 1942 pg/ml). CONCLUSION: The value of the FSH/LH ratio in patients with normal FSH levels, may have a role in determining the appropriate stimulation protocol and predict cycle cancellations.

RESUMEN

OBJECTIVE: To determine whether social media, specifically Facebook, is an effective tool for improving contraceptive knowledge. METHODS: English-speaking women aged 18-45 years receiving care at an urban academic center obstetrics and gynecology clinic were included and randomized to a trial of standard contraceptive education and pamphlet (n=74) compared with standard contraceptive education and Facebook (n=69) information for contraception counseling. Contraceptive knowledge was evaluated preintervention and postintervention by the Contraceptive Knowledge Inventory. We evaluated the effect of the intervention by raw score and percent increase in Contraceptive Knowledge Inventory score, participant satisfaction with counseling method, and contraceptive preference postintervention. All analyses were stratified by age group. RESULTS: The median raw postintervention Contraceptive Knowledge Inventory score was significantly higher in the Facebook compared with the pamphlet group (15 compared with 12, P<.001) as was percentage increase in the Contraceptive Knowledge Inventory score (36% compared with 12%, P<.001). Participant satisfaction with counseling method was significantly higher in the Facebook group (median 10 compared with 6, P<.001). Participant contraceptive preference for long-acting reversible contraceptives (LARCs; intrauterine device or implant) postintervention was significantly greater in the Facebook compared with the pamphlet group (57% compared with 35%, P=.01). Among women currently using none or barrier contraception, contraceptive preference for implants was significantly greater in the Facebook compared with the pamphlet group (26% compared with 5%, P=.02), although, when analysis was extended to include implant or intrauterine device, LARCs were not significantly higher in the Facebook compared with the pamphlet group (48% compared with 33%, P=.19). CONCLUSION: Social media as an adjunct to traditional in-office counseling improves patient contraceptive knowledge and increases patient preference for LARCs.
