Background : In order to decrease the high rate of multiple gestation pregnancies following in vitro fertilization (IVF), elective transfer of a single embryo (eSET) in good prognosis patients has been proposed. The purpose of this dissertation is to evaluate the present efficacy of eSET policies and to investigate whether modifications to patient guidelines could better identify patients who should be targeted for eSET. Methods : De- identified patient records from a private fertility center were reviewed to identify patients who had undergone IVF from 2006 through 2012. Three analyses were undertaken : (1) Comparing the equivalency of pregnancy and live-birth rates between patients opting for single blastocyst transfer (eSBT) and double blastocyst transfer (eDBT), (2) Assessment of whether clinical factors associated with multiple gestation pregnancies could be identified by comparing multiple and singleton gestation cycles, and (3) Development of a predictive model for the probability of cycle failure among young patients, by examining patients younger than 35 who failed to achieve a live-birth and those who attained a live-birth. Results : No significant differences in pregnancy and live-birth rates were observed between the eSBT and eDBT groups, however, clinical equivalence was only demonstrated for pregnancy rates. Odds of multiple birth decreased as maternal age increased, whereas risk increased in cycles with a fertilization rate >80%, when embryos were transferred at the blastocyst stage, and when the second best embryo transferred was graded as "good". The most relevant early predictors of cycle failure among young patients were a history of previous preterm or full-term live-birth, biochemical pregnancies and spontaneous abortions, day 3 follicle stimulating hormone level, antral follicle count, and number of follicles larger than 14mm on the day of human chorionic gonadotropin administration. Conclusions : While we are moving in the right direction towards clinical efficacy in eSET, addressing potential gaps in clinical guidelines could further increase acceptability of the procedure. In considering both clinical patient factors and embryo cohort characteristics, a more comprehensive profile of patients best suited for eSET could be developed that would increase the successfulness of the procedure, while simultaneously decreasing the high rate of multiple gestation pregnancies seen in IVF

OBJECTIVES: Up to a quarter of pregnant individuals with SLE have small for gestational age (SGA) infants. We aimed to characterize placental pathology associated with SGA infants in SLE. METHODS: We retrospectively analysed SLE deliveries with placental analysis at UCSD from November 2018 to October 2023, comparing SLE pregnancies resulting in SGA to those that did not, and additionally, to matched pregnancies with SGA but without SLE. RESULTS: Placental analysis was available only for 28/70 (40%) SLE deliveries, which had high rates of adverse outcomes (75%). All exhibited at least one histopathologic abnormality. Key findings distinguishing 12 SLE placentas resulting in SGA infants (vs.16 without) included small placental disc for gestational age (100% vs 56%, P = 0.01), placental disc infarct (50% vs 6%, P = 0.02) and increased perivillous fibrin deposition (PVFD, 58% vs 0%, P = 0.001). All seven SLE placentas with increased PVFD resulted in SGA infants. Compared with matched non-SLE pregnancies with SGA (n = 36), the only distinguishing placental lesion was a higher prevalence of increased PVFD in SLE-associated SGA (58% vs 22%, P = 0.03). CONCLUSION: The higher prevalence of increased PVFD in placentas of SLE-associated SGA may indicate a specific mechanism of placental injury leading to SGA in this context. Thus, its presence, particularly in context of SGA, should prompt providers to screen for an underlying autoimmune disease, including SLE. Systematic placental examination in context of SLE and associated autoimmune diseases could help evaluate responses to existing therapies, comparative studies of novel therapies and correlation to adverse outcomes.

Background

Threatened preterm birth is the most common reason for antepartum hospitalization in the United States, accounting for approximately 50% of these admissions. However, fewer than 10% of patients with inpatient evaluation for signs or symptoms of preterm labor ultimately deliver before term.

Objective

This study aimed to generate predictive models to assess the risk of preterm delivery and time to delivery based on clinical signs and symptoms of patients evaluated in our institution for preterm labor concerns.

Study design

This was a retrospective cohort study of singleton pregnancies evaluated for signs and/or symptoms of preterm labor, including contractions, abdominal pain, vaginal bleeding, and short cervix, between 22 0/7 and 33 6/7 weeks of gestation. Inpatient evaluations were classified by patient presentation: (1) symptomatic with cervical findings (transvaginal cervical length of <2.5 cm or cervical dilation of ≥2.0 cm), (2) asymptomatic with cervical findings, and (3) symptomatic without cervical findings. The primary outcomes included incidence of spontaneous preterm birth and interval from presentation to delivery, compared between groups. The risk of preterm delivery was evaluated using log-binomial regression, and presentation to delivery timing was assessed by survival analysis and Cox proportional hazards modeling.

Results

Of 631 patients with preterm labor concerns, 96 (16%) were symptomatic with cervical findings on evaluation, 51 (8%) were asymptomatic with cervical findings, and 466 (76%) were symptomatic without cervical findings. The occurrence of preterm birth was significantly higher among symptomatic patients with cervical findings (49%) than among those with cervical findings alone (31%) or symptoms alone (11%) (P<.0001). In addition, symptomatic patients with cervical findings were significantly more likely to deliver within 48 hours (20%), 1 week (30%), 2 weeks (33%), and 1 month (43%) of presentation than patients with cervical findings alone (2%, 2%, 6%, and 10%, respectively) or symptoms alone (0.4%, 1%, 1.5%, and 5%, respectively) (P value for trend<.0001). Adjusted for gestational age at presentation and previous preterm birth, the overall risk of preterm delivery was significantly higher among patients with symptoms and cervical findings than among patients with cervical findings alone (relative risk, 2.81; 95% confidence interval, 1.74-4.54) or symptoms alone (relative risk, 4.39; 95% confidence interval, 3.16-6.09). Adjusted for the same variables, symptomatic patients with cervical findings were also at higher risk of delivery over time after assessment than patients with cervical findings alone (hazard ratio, 2.06; 95% confidence interval, 1.47-2.90) or symptoms alone (hazard ratio, 2.16; 95% confidence interval, 1.74-2.70). The negative predictive value of these models suggested that only 1% of patients with isolated symptoms or cervical findings are at risk of preterm delivery within 1 week of initial presentation.

Conclusion

Symptomatic patients with cervical findings suggestive of preterm labor were at the greatest risk of preterm birth and a shorter interval from presentation to delivery. The study findings supported a risk profile that may facilitate the selection of patients most appropriate for admission and targeted management. Nonetheless, as nearly 50% of patients meeting this risk profile subsequently deliver at term, future research is needed to identify which of these patients will require intervention.

Objective

We assessed the proportion of medication versus suction aspiration abortions before and after the onset of the COVID-19 pandemic in a health system that did not limit access to abortion.

Study design

We conducted an interrupted time series analysis among patients having an abortion at 10 weeks gestation or less at Planned Parenthood health centers in San Diego, Imperial, and Riverside Counties in California. Centers required in-person follow up for medication abortion throughout the pandemic. We compared the nine months prior to the pandemic (June 2019 to February 2020) to the first nine months of the pandemic (April 2020 to December 2020), with March 2020 as a washout period.

Results

There was an average monthly increase of 0.78% in the proportion of medication abortions from June 2019 to February 2020 (p = 0.01, pre-pandemic trend). Immediately following the start of the pandemic, there was an estimated increase in the proportion of medication abortions of 2.58% (p = 0.23, post-level change). However, the monthly pre-pandemic trend towards medication abortions reversed by 1.07% after the start of the pandemic (p = 0.02, post-trend change), for an average monthly decrease in the proportion of medication abortions of 0.29% from April to December 2020 (p = 0.37, pandemic trend).

Conclusions

The trend towards medication abortions that was present before the COVID-19 pandemic reversed after an initial increase in medication abortions at the start of the pandemic.

Implications

Both types of abortion should remain available during public health emergencies. Further research is needed to understand how the pandemic affected abortion methods in areas with limited access and in health centers that did not require two in-person appointments for medication abortions.

This study aims to determine whether a novel cervical cancer screening toolkit will increase rates of pap test completion and HPV vaccination among Somali women living in the United States. We conducted a randomized controlled, pilot trial from June 2021 to February 2022. Somali women aged 21 to 70 were randomized to either receive a toolkit (infographic, video and an in-person health seminar) or not. Health passports confirming a completed pap test and/or HPV vaccination by clinician signature were used to measure outcomes. The primary outcome was pap test completion and the secondary outcome was HPV vaccination. We enrolled 57 participants. Patients randomized to the treatment arm were significantly more likely to have had a pap test (53.7% vs. 3.7%, p < 0.0001) and were also more likely to have received the HPV vaccine (10.7% vs. 3.7%, p = 0.6110). This toolkit increased rates of pap test completion and more participants in the intervention arm received HPV vaccination, though numbers were low. The study design may serve as a reproducible model to determine the effectiveness of patient education materials.

Background Impaired brain development in fetuses with congenital heart disease (CHD) may result from inadequate cerebral oxygen supply in utero. Purpose To test whether fetal cerebral oxygenation can be increased by maternal oxygen administration, effects of maternal hyperoxia on blood oxygenation of the placenta and fetal brain were examined by using blood oxygenation level-dependent (BOLD) functional MRI. Materials and Methods In this prospective study, BOLD MRI was performed in 86 fetuses (56 healthy fetuses and 30 fetuses diagnosed with CHD) between 22 and 39 weeks gestational age (GA) from May 2015 to December 2017, with the following study design: phase I, 2-minute resting state at baseline (room air); phase II, 6-minute maternal hyperoxia with 100% oxygen; and phase III, 5.6-minute return to resting state. After motion correction, the signals were averaged over the placenta and fetal brain and converted to the change in R2* (ΔR2*). Fetuses with CHD were categorized into those with a single ventricle (SV) or two ventricles (TVs) and those with aortic obstruction (AO) or non-AO. Data were analyzed by using generalized linear mixed models controlling for GA and sex. Results Placental ΔR2* increased during maternal hyperoxia in healthy fetuses and fetuses with CHD, but it was higher in SV CHD (mean ΔR2*, 1.3 sec^-1 ± 0.1 [standard error; P < .01], 1.9 sec^-1 ± 0.2 [P < .01], and 1.0 sec^-1 ± 0.3 [P < .01], respectively, for control fetuses, fetuses with SV CHD, and fetuses with TV CHD). Placental ΔR2* during maternal hyperoxia changed with GA in healthy control fetuses and fetuses with SV or AO CHD (ΔR2* per week, 0.1 sec^-1 ± 0 [P < .01], 0.2 sec^-1 ± 0 [P = .01], and 0.2 sec^-1 ± 0 [P = .01], respectively), but not in fetuses with CHD and TV or non-AO. Fetal brain ΔR2* was constant across all phases in healthy control fetuses and fetuses with TV CHD but increased during maternal hyperoxia in fetuses with SV or AO CHD (mean ΔR2*, 0.7 sec^-1 ± 0.2 [P = .01] and 0.5 sec^-1 ± 0.2 [P = .02], respectively). Conclusion Six minutes of maternal hyperoxia increased placental oxygenation in healthy fetuses and fetuses with congenital heart disease, and it selectively increased cerebral blood oxygenation in fetuses with single ventricle or aortic obstruction. © RSNA, 2019 Online supplemental material is available for this article.

PURPOSE: To evaluate the impact of an interleukin-1 (IL-1) antagonist anakinra (Kineret®) on endometriosis-related quality of life (QoL), pain, and inflammatory biomarkers. METHODS: This was a single-site, randomized, double-blinded, placebo-controlled, cross-over pilot clinical study of patients recruited at an academic specialty clinic. Eligible participants were females aged 18-45 years with menstrual cycles every 24-32 days. Subjects had moderate to severe dysmenorrhea and either a surgical diagnosis of endometriosis or an endometrioma on imaging. Subjects were randomly assigned in a double-blind fashion to receive either the study drug or placebo administered as daily injections during the first 3 periods and then the alternate intervention for the next 3 periods. RESULTS: Fifteen subjects completed the 6 menstrual cycle study. After each period, they completed the Endometriosis Health Profile-30 (EHP-30) QoL questionnaire and an assessment of dysmenorrhea using a 0-100 Visual Analogue Scale (VAS). All domains of the EHP-30 showed a trend towards improvement, with significant improvements in powerlessness (54.5 vs 63.3, p = 0.04) and self-image (58.1 vs 66.7, p = 0.03) on the study drug compared to placebo. The mean dysmenorrhea VAS also trended toward improvement with a score of 37.5 during active treatment and 42.6 with placebo (p = 0.26). No difference in menstrual cycle length was detected (29.3 days vs 27.7 days, p = 0.56). There were significant differences in multiple inflammatory biomarkers between the study drug and placebo, including BDNF, IL-1, and IL-6 among certain groups. CONCLUSION: With all EHP-30 domains and the dysmenorrhea VAS showing either a statistical improvement or trend towards improvement, there is justification for a larger study. As no impact on menstrual cycles was detected, anakinra may be a particularly impactful option for women desiring fertility. Additional evaluation is needed on the role of anakinra on inflammatory markers given significant reductions were identified in multiple biomarkers.

INTRODUCTION: Reducing cardiopulmonary bypass (CPB) induced inflammatory injury is a potentially important strategy for children undergoing multiple operations for single ventricle palliation. We sought to characterize the soluble receptor for advanced glycation end products (sRAGE), a protein involved in acute lung injury and inflammation, in pediatric patients with congenital heart disease and hypothesized that patients undergoing single ventricle palliation would have higher levels of sRAGE following bypass than those with biventricular physiologies. METHODS: This was a prospective, observational study of children undergoing CPB. Plasma samples were obtained before and after bypass. sRAGE levels were measured and compared between those with biventricular and single ventricle heart disease using descriptive statistics and multivariate analysis for risk factors for lung injury. RESULTS: sRAGE levels were measured in 40 patients: 19 with biventricular and 21 with single ventricle heart disease. Children undergoing single ventricle palliation had a higher factor and percent increase in sRAGE levels when compared to patients with biventricular circulations (4.6 vs. 2.4, p = 0.002) and (364% vs. 181%, p = 0.014). The factor increase in sRAGE inversely correlated with the patients preoperative oxygen saturation (Pearson correlation (r) = -0.43, p = 0.005) and was positively associated with red blood cell transfusion (coefficient = 0.011; 95% CI: 0.004, 0.017; p = 0.001). CONCLUSIONS: Children with single ventricle physiology have greater increase in sRAGE following CPB as compared to children undergoing biventricular repair. Larger studies delineating the role of sRAGE in children undergoing single ventricle palliation may be beneficial in understanding how to prevent complications in this high-risk population.

Age-related pelvic floor muscle (PFM) dysfunction is a critical defect in the progression to pelvic floor disorders (PFDs). Despite dramatic prevalence of PFDs in older women, the underlying pathophysiology of age-related PFM dysfunction remains poorly understood. Using cadaveric specimens, we quantified aging effects on functionally relevant PFM properties and compared PFMs with the appendicular muscles from the same donors. PFMs, obturator internus, and vastus lateralis were procured from younger (N = 4) and older (N = 11) donors with known obstetrical and medical history. Our findings demonstrate that PFMs undergo degenerative, rather than atrophic, alterations. Importantly, age-related fibrotic degeneration disproportionally impacts PFMs compared to the appendicular muscles. We identified intramuscular lipid accumulation as another contributing factor to the pathological alterations of PFMs with aging. We observed a fourfold decrease in muscle stem cell (MuSC) pool of aged relative to younger PFMs, but the MuSC pool of appendicular muscles from the same older donors was only twofold lower than in younger group, although these differences were not statistically significant. Age-related degeneration appears to disproportionally impact PFMs relative to the appendicular muscles from the same donors. Knowledge of tissue- and cell-level changes in aged PFMs is essential to promote our understanding of the mechanisms governing PFM dysfunction in older women.
