    Abstract Given limited data regarding future planning specific to Fragile X Syndrome (FXS) individuals and the growing population of individuals within this community, this study sought to explore the concerns and challenges caregivers of individuals affected by FXS encounter when considering long-term support plans. This involved identifying the reasons individuals with FXS continue to reside with family and the reservations caregivers have regarding future supports and living arrangements. We administered an anonymous online survey consisting of 34 questions assessing eligibility, living arrangements/supports, and future concerns. We found that most individuals with FXS were affected with moderate Intellectual and Developmental Disabilities (IDD) and co-occurring behavioral conditions but had overall good health. The majority of individuals with FXS currently resided with family due to parental desire, their own desire, and the inability to live independently. For one-third of caregivers, the plan for future living arrangements is to continue residing with family members long-term. A large proportion of caregivers had not considered alternative arrangements or were unsure. More than 70% of caregivers of individuals with FXS are concerned about multiple aspects of the individual's future. Caregivers of younger individuals are the most concerned, but also believe they have time before they need to plan or are unable to currently assess the future need for support.

    Abstract Objective: To determine an optimal timing strategy for rescue corticosteroids in gravidas with preterm prelabor rupture of membranes (PPROM) prior to 33 0/7 weeks.
    Methods: This was a retrospective cohort analysis of 109 gravidas with a singleton gestation and PPROM between 23 0/7 and 32 6/7 weeks who delivered at a single inner city tertiary care center. The time of the actual first dose of corticosteroids was chosen as Time 0. The date and time of labor onset, chorioamnionitis, heavy bleeding, cord prolapse, or fetal heart rate decelerations warranting delivery were recorded, as well as the date and time of delivery. We then compared hypothetical timing strategies for administration of the rescue course of corticosteroids at either 1, 2, or 3 weeks after the first course if still undelivered, compared to a strategy of withholding the rescue course until the recognition of spontaneous labor or the need for delivery. For each strategy, we calculated the percentage of gravidas who would have delivered within the optimal window after rescue course corticosteroids, defined as delivery at 24 h to 7 days from the first rescue dose.
    Results: The median time from PPROM to delivery among the 109 gravidas was 8.9 days (interquartile range 4.4-17.9 days). Forty-eight (44%) gravidas delivered within the first week after initial corticosteroid administration, leaving 61 (56%) eligible for a rescue dose. In our hypothetical models, the strategy of giving rescue corticosteroids at either 1, 2, or 3 weeks from the first course would have resulted in 34.4%, 23.0%, and 19.7% of infants being born at 24 h to 7 days after the first rescue dose, respectively. These differences among the three groups or between any two groups were not statistically significant. However, all fixed interval strategies were statistically superior to the strategy of waiting for spontaneous labor or the need for delivery, in which only 4.9% would have delivered within the optimal window.
    Conclusion: In gravidas with PPROM prior to 33 0/7 weeks, giving rescue corticosteroids at a fixed interval of either 1, 2, or 3 weeks after the first course would result in a greater percentage of infants being born within the optimal 24 h to 7 day window compared to administering the rescue course at the onset of labor, infection, bleeding, or abnormal fetal heart rate tracing.

    Abstract Objective: To study the relationship between high antimüllerian hormone (AMH) levels in oocyte donors and embryo development and pregnancy outcomes among donor oocyte recipients.
    Design: Retrospective cohort study.
    Setting: Donor Egg Bank Database.
    Patients: Patients undergoing in vitro fertilization using vitrified donor oocytes from 35 in vitro fertilization centers in the United States between 2013 and 2021. For each recipient, the first oocyte lot that was received with a planned insemination and embryo transfer (ET) was included.
    Intervention: Oocyte donor-recipient cycles.
    Main outcome measures: Ongoing pregnancy rate (OPR) per ET.
    Results: A total of 3,871 donor oocyte-recipient thaw cycles were analyzed. On the basis of donor AMH serum concentration, cycles were stratified into the high AMH group (AMH ≥5 ng/mL; n = 1,821) and the referent group (AMH <5 ng/mL; n = 2,050). Generalized estimating equation models were used to account for donors that contributed more than one lot of oocytes. The number of usable embryos per lot (median [interquartile range]) was significantly increased in the high AMH group (2 [2-4]) compared with the referent group (2 [1-3]) (relative risk [RR] 1.06; confidence interval [CI] 1.01-1.12). Among recipients with a planned ET, there was no difference in OPR between the high AMH group (45.4%) and the referent group (43.5%) (RR 1.04; 95% CI 0.94-1.15). Among preimplantation genetic testing for aneuploidy cycles, the embryo euploidy rate per biopsy was similar at 66.7% (50%-100%) in both groups (RR 1.04; CI 0.92-1.17). The OPR per euploid ET among patients who used preimplantation genetic testing for aneuploidy was also comparable, at 52% in the high AMH group and 54.1% in the referent group (RR 0.95; CI 0.74-1.23).
    Conclusion: This large national database study observed that there was no association between a high level of AMH (≥5 ng/mL) in oocyte donors and an OPR in the recipient after the first ET. On the basis of these findings, recipients and physicians can be reassured that oocyte donors with a high AMH level can be expected to produce outcomes that are at least as good as donors with an AMH level (<5 ng/mL).

    Abstract Purpose: There is an unclear relationship between estradiol levels and fresh embryo transfer (ET) outcomes. We determined the relationship between estradiol on the day of trigger, in fresh ET cycles without premature progesterone elevation, and good birth outcomes (GBO).
    Methods: We identified autologous fresh ET cycles from 2015 to 2021 at multiple clinics in the USA. Patients with recurrent pregnancy loss, uterine factor, and elevated progesterone on the day of trigger (progesterone > 2 ng/mL or 3-day area under the curve > 4.5 ng/mL) were excluded. The primary outcome was GBO (singleton, term, live birth with appropriate weight). Log-binomial generalized estimating equations determined the likelihood of outcomes.
    Results: Of 17,608 fresh ET cycles, 5025 (29%) yielded GBO. Cycles with estradiol
    Conclusion: In fresh ET cycles, higher estradiol levels were associated with an increased prevalence of GBO until estradiol 2000-2999 pg/mL, thereafter plateauing. In fresh ET candidates, elevated estradiol levels should not preclude eligibility though premature progesterone rise, and risk of ovarian hyperstimulation syndrome must still be considered.

    Abstract Objective: To evaluate differences in reproductive and neonatal outcomes based on the time interval from cesarean delivery to subsequent frozen embryo transfer (FET) DESIGN: Retrospective cohort SUBJECTS: Women undergoing autologous elective single embryo transfer (eSET) FET following prior cesarean delivery EXPOSURE: Time from prior cesarean delivery to subsequent FET MAIN OUTCOME MEASURES: Live birth RESULTS: A total of 6,556 autologous eSET FET cycles were included. FET cycles were divided into eight groups based on the time interval from prior cesarean delivery to subsequent FET in months. Time was also evaluated as a continuous variable. The proportion of live births did not differ significantly across all time interval groups and over continuous time (range: 40.0% - 45.6%, adjusted (adj) p = 0.572, continuous adj p = 0.599). Mean gestational age at the time of delivery did not significantly differ as the time between prior cesarean delivery and subsequent FET increased (range: 37.3 - 38.4 weeks, adj p = 0.87, continuous adj p = 0.06). When time was evaluated continuously, the proportion of preterm births was higher with a shorter time between cesarean delivery and subsequent FET (p = 0.02). Mean birth weight ranged from 3181 grams to 3470 grams, with a statistically significant increase over time (continuous adj p = 0.01). However, the proportions of extremely low birth weight, very low birth weight, and low birth weight did not significantly differ.
    Conclusion: There were no significant differences in reproductive outcomes based on the time interval from cesarean delivery to FET, including live birth. The proportion of preterm deliveries decreased with a longer time between cesarean delivery and FET. Differences in mean neonatal birth weight were not clinically significant, as the proportion of low-birth-weight neonates was not significantly different over time. While large, this sample cannot address all outcomes associated with short interpregnancy intervals, particularly rarer outcomes such as uterine rupture. When counseling patients, the timing of FET following cesarean delivery must be balanced against the risks of increasing maternal age on reproductive and neonatal outcomes.
