P-240 Is the intelligent Data Analysis Score (iDAScore) a reliable tool to predict pregnancy? Our center’s experience

Abstract Study question Is the intelligent Data Analysis Score (iDAScore) reliable in predicting a positive pregnancy test, clinical pregnancy and miscarriage rate after single vitrified-warmed blastocyst transfer (SVBT)? Summary answer There is a significant increase in positive pregnancy test and clinical pregnancy rates as iDAScore increases. The miscarriage rate is lower with increased iDAScore. What is known already With the improvement of assisted reproductive technology (ART), elective single embryo transfer has become a standard. Optimizing embryo selection is a major challenge to increase reproductive outcomes. The Gardner embryo grading system is widely adopted for the evaluation of blastocyst quality, but this tool is subject to inter- and intra-variability. In recent years, artificial intelligence has found diverse applications in healthcare. Based on time-laps sequences of > 180’000 developing embryos, iDAScore is a new deep-learning model for objective and standardized blastocyst scoring. However, its reliability in predicting pregnancy and miscarriage rates remains unknown. Study design, size, duration This monocentric retrospective pilot study was conducted from May 2023 to December 2023. A total of 206 homologous SVBT cycles from 206 patients were analyzed (one patient, one cycle). Exclusion criteria included: cycles involving preimplantation genetic testing, multiple and/or fresh blastocyst transfer, and blastocysts obtained after testicular sperm extraction. All vitrified-warmed blastocysts were scored using iDAScore version 1.0 model, ranging from 1 – 9.9. Participants/materials, setting, methods Scores were stratified into 3 groups: high-score (9.9 – 7.7), medium-score (7.6 – 5.5) and low-score (5.4 – 3.1). For each group, positive pregnancy test, clinical pregnancy and miscarriage rates were analyzed. SVBT cycles were then stratified into four maternal age groups (< 35, 35-37, 38-40, >41 years) and the same outcomes were analyzed. χ2 was used for statistics analysis. Main results and the role of chance Mean maternal age was 36.8 ± 4.9. Among the 206 vitrified-warmed blastocysts, 122 were scored as high-score, 57 as medium-score and 27 as low-score. Positive pregnancy test rate was significantly higher with increased iDAScore with 58% in the high-score group, 36.8% in the medium-score group and 17% in the low-score group (p < 0.0001). Clinical pregnancy rate, defined as the visualization of a fetal heartbeat at ultrasound scan, was also significantly higher with increased iDAScore, with 51.6% in the high-score group, 31.6% in the medium-score group and 17% in the low-score group (p < 0.0001). The miscarriage rate was lower with increased iDAScore, with 8.1% in the high-score group, 16.6% in the medium-score group and 50% in the low-score group, but this difference was not statistically significative (p 0.032). When adjusted to age group however, the miscarriage rate was found to be significantly lower in the high-score group when compared to the medium-score group (p < 0.0001); statistical analysis was not achieved in the low-score group due to the small sample size. Limitations, reasons for caution The major limitation of our study is its small sample size. Data collection is ongoing, to increase the study power. Additionally, many other factors, such as genetic, hormonal, metabolic and/or immunological, may play a role in achieving pregnancy. Wider implications of the findings Our results indicate that iDAScore may be a strong predictor of pregnancy and could be used as a complementary tool to the Gardner embryo grading system in the decision-making process of which blastocyst to transfer.

P-267 The morula stage. Is it time to repair?

Abstract Study question Are there statistically significant differences in embryo’s fate when exclusion or extrusion of blastomeres is detected along development? Summary answer According to our results, exclusion or extrusion of blastomeres affects the embryo’s subsequent viability, suggesting that different biological processes are involved in its appearance. What is known already The morula stage is a clear example of embryo plasticity, being a critical step towards blastocyst development. One morphokinetic parameter observed at this stage is the exclusion (before compaction) and extrusion (during or after compaction) of blastomeres. Exclusion and extrusion seem to be related to embryo self-correction phenomena and they are considered negative criteria due to potential associations with tight junction failures, gene expression, aneuploidies, or a high degree of mosaicism. However, the moment in which those phenomena are detected, can have different origins and though different consequences in embryo development. Study design, size, duration A total of 668 fertilized embryos and cultured to the blastocyst stage were included in the study. Embryo cohorts correspond to 158 consecutive patients that underwent an IVF treatment with fresh single blastocyst transfer and all their cohorts, between June 2017 and September 2022. Data recovered during culture in time-lapse incubator regarding the extrusion or exclusion of cells and the final fate of the transferred and the cohort embryos were retrospectively analysed. Participants/materials, setting, methods Embryos were cultured in single culture medium (CSCC®, Irvine Scientific) in a time-lapse incubator (MIRI-TL®, ESCO Medical). Embryos were evaluated for the time of exclusion/extrusion, number and volume of excluded/extruded cells and their final fate (transferred and the result, vitrified, discarded). For those transferred, Beta-hCG was performed 14 days after transfer and if positive clinical pregnancies were confirmed 3 weeks later. Data were analysed using IBM SPSS Statistics v25.0, with p < 0.05 indicating statistical significance. Main results and the role of chance Of the 668 analysed embryos, 340 were deemed “useful”: 225 were transferred (158 fresh, 67 cryotransferred after fresh negative pregnancy test), and 115 remain still vitrified. The rest, 328, were considered “non-useful”: 84 discarded and 244 blocked. 37% of the embryos presented total compaction and 63% partial, being 70.1% exclusion, 9.7% extrusion and 20.2% both phenomena. Exclusion/extrusion was significantly higher (p < 0.05) in non-useful embryos compared to the useful ones. In the distribution with regards to the final fate, significant differences were found (p < 0.05) being 78% exclusion, 8.8% extrusion and 13.3% both for useful, and 53.8% exclusion, 5.8% extrusion and 40.4% both for non-useful. There were statistically significant differences (p < 0.05) in the volume and number of cells excluded/extruded and the fate, being higher in those that resulted non-useful. ROC analysis showed that the volume occupied by excluded cells influences the embryo’s fate (AUC=0.738). Regarding transferred embryos, those that presented the phenomenon and resulted in a positive beta-hCGs, 95.8% was exclusion, none of them extruded cells and 4.2% both. For the negatives, 71% of exclusion, 11.4% of extrusion and 17.1% both, resulting in non-significant differences (p = 0.055). No significative differences were found either for the ones that resulted in a clinical pregnancy. Limitations, reasons for caution Although no statistical differences were found according to the moment of exclusion of blastomeres, before or after compaction, and the pregnancies, there is a clear trend in the sooner it happens the more embryo viability. And increase in the sample size might be helpful to confirm it. Wider implications of the findings The establishment of new parameters can improve embryo selection to help embryologists discriminating between embryos that appear to be of similar quality.

P-417 Transmyometrial embryo transfer as a reliable alternative to challenging transcervical embryo transfer

Abstract Study question Can transmyometrial embryo transfer be a reliable alternative to challenging transcervical embryo transfer Summary answer In selected cases, where transcervical embryo transfer is impossible, transmyometrial embryo transfer is a suitable alternative. What is known already Transmyometrial embryo transfer (TMET) can be a last resort option for challenging transcervical embryo transfer (ET). Indications for TMET include; failure to access the uterus transcervically due to previous cervical surgery, stenosed cervix which will not dilate or due to challenging cervical anatomy. This technique is done by passing a long needle through the myometrium to enter the uterine cavity. This can be a less traumatic option than multiple attempts at ET with the added consequences of using a tenaculum. This centre has been performing TMET since 2004. Study design, size, duration This was a retrospective audit looking at TMET cases from 2004 to 2023. 125 cases were recorded and reviewed. Participants/materials, setting, methods The results are from a single centre unit which receives referrals for TMET from outside units. This was an audit and cases were initially found by reviewing all cases of embryo transfer from 2004. Where TMET had been recorded, the notes were then collected to ascertain patient demographics, reasons for transmyometrial embryo transfer, embryo grading and pregnancy outcomes. Main results and the role of chance Since 2004, 125 cases of TMET were recorded. 16 notes were excluded as there was unclear documentation on the type of embryo transfer, leaving 109 cases. There were 23 positive pregnancy tests, 6 documented scans showing a fetal heart at 7 weeks and three documented live births. Indication for TMET was mainly a failure to enter the uterine cavity due to stenosed cervix. In all cases of TMET, patient’s had undergone multiple attempts at accessing the uterine cavity, along with multiple attempts at hysteroscopy and dilatation. Only after trying all other options was TMET used, and mainly as a last resort measure. All cases were planned and used frozen blastocysts. There were no complications to TMET. Due to the last resort nature of TMET and the reasons for undergoing assisted reproductive technology it is unlikely these pregnancies were by chance. Limitations, reasons for caution Due to the length of time this centre has been doing TMET the documentation from the earlier cases was poor and births could have been missed due to poor follow up. Training in TMET is difficult due to the low numbers per year. Wider implications of the findings TMET remains a safe and reliable alternative option when facing a challenging transcervical embryo transfer and should be used as a last resort measure.

Exploring Reasons for Loss to Follow-up in Pregnancy of Unknown Location: A Mixed-Methods Study.

Objective: To quantify proportions of loss to follow-up in patients presenting with a pregnancy of unknown location and explore patients' perspectives on follow-up for pregnancy of unknown location. A pregnancy of unknown location is a scenario in which a patient has a positive pregnancy test but the pregnancy is not visualized on transvaginal ultrasound. Study Design: We conducted a retrospective cohort study of patients with pregnancy of unknown location who presented to an urban academic emergency department or complex family planning outpatient office. We sought to calculate the proportion of patients lost to follow-up, defined as inability to contact the patient within 2 weeks. We then conducted focus groups of patients diagnosed with a pregnancy of unknown location. We used thematic analysis to identify themes related to follow-up. Results: We reviewed 464 charts of patients diagnosed with pregnancy of unknown location. The median age in this cohort was 27 with most patients identifying as Black (80%, n = 370) and using public insurance (67%, n = 315). When looking at loss to follow-up rates, Black patients experienced loss to follow-up (20%, n = 72) more often than White patients (4%, n = 2; p = 0.003). Focus group participants had a mean age of 31.8+/-4.8, and the majority were of Black race (n = 16, 72.7%). Participants identified barriers to follow-up including the long duration of management, general inconvenience, and poor communication with their health care team. Participants felt a burden of responsibility to learn about their condition and to self-advocate for their follow-up and communication of results. Conclusions: These data indicate that Black patients are more likely to experience loss to follow-up compared with White patients during monitoring for pregnancy of unknown location. Patients identified many barriers to follow-up and felt that successful follow-up required substantial self-efficacy.

P-730 A feasibility study of the impact of the level of exposure to ambient air pollutants on outcomes of assisted reproductive technologies

Abstract Study question What is the impact of air pollution exposure on outcomes for couples having IVF treatment? Summary answer Environmental exposure to high levels of air pollutants may negatively influence IVF outcomes with potential implications for fertility treatment. What is known already Air pollutants are harmful substances in the atmosphere that have adverse effects on human health. Increased levels of air pollutants have been associated with respiratory disorders, cardiovascular disease, and increased morbidity in humans across all age groups. Existing evidence suggests that increased exposure to air pollutants may adversely affect fertility. The relationship between air pollutants and IVF outcomes remains poorly understood. Study design, size, duration This was an ethically approved prospective observational feasibility study conducted over a two-year period. Ten couples due to undergo an IVF cycle were recruited from a fertility centre in the UK. Environmental exposure to ambient air pollutant for particulate matter (PM) 2.5 and 10 micron size was measured using portable AirBeam monitors over the course of two weeks from commencement of the ovarian stimulation regime. Participants/materials, setting, methods Eligible participants were those aged 18-35 years old, undergoing fresh IVF, with a good ovarian reserve and ability to provide informed consent. Data of interest included: BMI, age, parity, ethnicity, smoking status. IVF data included: number of oocytes retrieved, embryo quality and cycle outcomes. AirBeam device data was extracted, analysed and correlated with IVF outcomes. Participants feedback was sought for qualitative input for future studies. Main results and the role of chance Total of 28,269 data points of ambient air pollutant data for PM 2.5 and 10 micron size were recorded amongst the ten participants. One participant was exposed to significantly high air pollutant levels during ovarian stimulation on certain days (PM2.5 - 81.06 µg/m³ and PM10 - 154.48 µg/m³) compared to standard annual air pollution level for the UK of 25 µg/m³ for PM2.5 and 40 µg/m³ for PM10. Two women did not have embryo transfer due to embryo arrest. Of those who had transfer, 50% (n = 4) had positive pregnancy tests however three experienced early pregnancy losses. At the time of writing there was one ongoing single viable pregnancy. On correlation of air quality data with clinical outcomes, the one participant who exhibited fluctuant very high exposure levels to the measured air pollutants, had unexpected low fertilization rate (20%) with IVF and no transfer due to embryo arrest. Of the nine participants returning the questionnaire feedback, all but one rated it acceptable to most acceptable to carry the device around. The main barrier was the size of device and battery life. All respondents were willing to recommend others to participate in a future similar study confirming feasibility to recruit. Limitations, reasons for caution As a feasibility study, with a limited sample size, our findings should be interpreted cautiously. The small cohort limits the generalisability of our results. Further research with larger sample sizes is required to validate our findings. Wider implications of the findings Understanding the impact of air pollutants on IVF outcomes is important for developing evidence-based guidance and interventions to optimise fertility treatment efficacy. Our study demonstrates the feasibility of personal air quality monitoring and emphasises the necessity for larger scale research and the practicality of pollutant exposure measurements in fertility treatments.

P-557 The contribution of PGT-A to PGT-M and PGT-SR clinical outcomes – A single centre retrospective analysis

Abstract Study question To determine if the introduction of concurrent testing with PGT-A has improved clinical outcomes for PGT-M/SR patients. Summary answer This study demonstrates that the introduction of concurrent testing may have improved clinical outcomes for this patient demographic irrespective of age. What is known already Preimplantation Genetic Testing (PGT) is utilised to investigate the genetic constitution of embryos. PGT-M (monogenic) and PGT-SR (structural rearrangements) are screening techniques considered in treatment for couples at risk of conceiving offspring with known genetic or structural chromosomal abnormalities respectively. Preimplantation Genetic testing for Aneuploidy (PGT-A) was developed in order to screen embryos for numerical chromosomal abnormalities, a leading cause of failed implantation. Nevertheless, routine use of PGT-A is discouraged due to lack of evidence regarding its efficacy. However, PGT-A is routinely used alongside PGT-M and PGT-SR despite the lack of evidence of its effectiveness in improving patient outcomes. Study design, size, duration The retrospective analysis of 496 PGT-M/SR single embryo transfer patient cycles between December 2013 and December 2021. Participants/materials, setting, methods The retrospective analysis of 496 PGT-M/SR single embryo transfer cycles at CRGH Portland was undertaken (single testing n = 77; concurrent testing n = 419). The clinical outcomes (positive urine pregnancy test, clinical pregnancy, live birth and miscarriage rates) were compared between groups using IBM SPSS Statistics (premium 27). Binary logistic regression was performed for statistical analysis, results with p < 0.05 were determined statistically significant. Main results and the role of chance Overall, concurrent testing was associated with statistically significant improved clinical outcomes compared to the reference group. Statistical significance was seen in positive urine pregnancy test (49% vs 68%, p = 0.012), clinical pregnancy (32.5% vs 63%; p = 0.000013), live birth rate (32.5% vs 59%; p = <0.00016) and miscarriage rates (34.2% vs 13%; p = 0.001). The results imply that the introduction of concurrent testing has improved the probability of obtaining a positive clinical outcome and has reduced the chance of miscarriage in this patient demographic. Further analysis showed concurrent testing improved the chances of obtaining a positive clinical outcome irrespective of the patients age or quality of the embryo. Limitations, reasons for caution This study has produced promising results. However, there are several limitations such as the small sample size, embryo biopsy techniques used, and the different molecular diagnostic techniques and providers utilised. Wider implications of the findings The results imply a justification for the use of PGT-A alongside PGT-M/SR screening techniques to improve embryo selection and clinical outcomes for this cohort of patients. Additionally, they demonstrate the efficacy of PGT-A in a previously underrepresented demographic. However, further research is required to confirm the clinical value of PGT-A.

P-467 Fertility preparedness and influencing factors in women undergoing fertility treatment: Turkish sample

Abstract Study question What is the level of fertility preparedness among women undergoing fertility treatment and what factors influence this preparedness? Summary answer The readiness of the participants to undergo fertility treatment was found to be high. Factors that increase and decrease women’s prepareadiness were also identified. What is known already It is a common problem in practice to stop and not continue infertility treatment, which has a long physical, emotional and financial burden. Although there are many reasons for this, it has been found that couples move from one treatment process to another without feeling ready. In addition to the stress of infertility and treatment, couples drop out of treatment due to low readiness. Therefore, measuring the readiness of couples prior to fertility treatment and determining the factors that influence readiness may be effective in the continuation and success of treatment. Study design, size, duration It was a descriptive and cross-sectional study conducted on 375 Turkish-speaking women in a virtual environment using the Google survey technique. Infertile women who received treatment in fertility clinics of any hospital or private IVF centers worldwide and spoke Turkish constituted the population of the research. The data were collected between February 2021 and January 2022. Participants/materials, setting, methods A total of 375 women with primary infertility who agreed to be part of the study were included. Data were collected by ‘Descriptive Information Form’, ‘Fertility History Form’ and ‘Fertility Preparedness Scale for Women Receiving Fertility Support’ measurement tools. The cut-off value of the Fertility Preparedness Scale (FPS) is 56 points (min 23 - max 115) and a score of less than 56 points indicates that the participant was not sufficiently prepared for fertility treatment. Main results and the role of chance In the present study, the mean score was X¯ = 83.01 (min 39-max115). Most of the participants (94.67%) were above the cut-off value. This showed us that 94.67% of the women had a high level of prepareadiness. Factors such as advancing age, prolongation of infertility, increase in number of treatments, female factor of infertility were negative factors related to fertility preparedness. Besides increased education level, increased income, secondary infertility, feel less pressure from their families and being able to share with the social circle about the treatment were positive factors that increased the woman’s prepareadiness for treatment.According to the results fertility prepareadiness it has a very important place in starting and continuing fertility treatment. There are many factors that influence fertility prepareadiness. If a woman/couple starts well prepared in this expensive and stressful treatment process, financial loss can be prevented, treatment success can be improved and treatment discontinuation can be reduced. Limitations, reasons for caution The fact that the study was conducted online and the possibility of participation of people at different stages of treatment (beginning, while waiting for a pregnancy test, etc.) may have affected the fertility prepareadiness results. Wider implications of the findings There is a need for an experimental randomized controlled trial with objective assessment of fertility prepareadiness. It would also be useful for health professionals to measure the prepareadiness of women/couples through pre-treatment assessment in clinics. Assessment of prepareadiness and identification of influencing factors is important to provide appropriate support. Trial registration number non-clinical trials

Predictive Value of Teratospermia During Initial Sperm Analysis on the Success of Intrauterine Insemination Cycles

ObjectiveTo evaluate the predictive value of sperm morphology, specifically teratospermia, seen during initial semen analysis on the success of intrauterine insemination (IUI) cycles and pregnancy outcomes. MethodsA retrospective cohort analysis on patients undergoing IUI at a large US fertility network. Baseline demographic characteristics, primary infertility diagnoses, and pregnancy outcomes were recorded. A total of 27,925 IUI cycles in 16,169 unique patients were analyzed. IUI cycles were grouped by a sperm morphology of 1% (n=3,799), 2% (n=5,506), 3% (n=4,857), or 4% or greater (n=13,763). The outcome measures were pregnancy rate (positive pregnancy test), clinical pregnancy rate (ultrasound confirmation of a gestational sac with a yolk sac around 5-6 weeks), live birth rate, and miscarriage rate. ResultsSperm morphology is a significant predictor of pregnancy rate (p= <0.001), clinical pregnancy rate (p=0.011), and live birth rate (p=0.026) following IUI. In each of these outcome measures, patients with 1% normal forms had the lowest percentage of success, and patients with 4% or greater normal forms had the most success. Relative outcome percentages, however, were similar in each group. Live birth rates in the 1%, 2%, 3% and > 4% group were 12.3%, 13.1%, 12.7% and 13.9%, respectively. Sperm morphology is not a significant predictor of miscarriage rate per clinical pregnancy post IUI (p=0.054). ConclusionsSperm morphology was a statistically significant predictor of pregnancy, clinical pregnancy, and live birth but not miscarriage rate after an IUI cycle. Higher morphology percentages were associated with increasingly favorable outcomes. However, the small observed differences did not demonstrate clinical significance.

Antimüllerian hormone levels are associated with time to pregnancy in a cohort study of 3,150 women

ObjectiveTo study the association between AMH and time to pregnancy. While it has been hypothesized that serum anti-Müllerian hormone (AMH) levels may indicate the chance of conception, findings have been mixed. Given that any association is expected to be modest, and it is possible that previous studies have been underpowered, we investigated this relationship in the largest prospective cohort to date. DesignProspective time-to-pregnancy cohort study. Subjects3,150 US women who had been trying to conceive for less than 3 months and had purchased a Modern Fertility Hormone Test. ExposureWe developed a discrete time-to-event model utilizing a binomial complementary log-log error structure within a generalized additive modeling framework, adjusting for confounding factors such as age, BMI, parity, smoking status, PCOS, and others. Sensitivity analyses were performed in women with regular menstrual cycles (21-35 days), who did not report using fertility treatments, using alternate AMH categories (<0.7, 0.7-8.5, >8.5 ng/mL), and AMH as a continuous measure. Main Outcome MeasuresPrimary outcomes included cumulative conception probability within 12 cycles and relative fecundability per menstrual cycle. Conception was defined by a self-reported positive pregnancy test. ResultsParticipants contributed 7.21 ± 5.32 cycles, with 1,325 (42.1%) achieving a pregnancy. Women with low AMH (<1ng/mL, n=427) had a lower chance of natural conception (Adjusted Hazard Ratio (adjHR 0.77, 95%CI 0.64, 0.94, p=0.009) compared to women with a normal AMH (1 - 5.5ng/mL). There was no difference between high (5.5+ ng/ml) and normal AMH categories (adjHR 1.11, 95% CI 0.94, 1.31, p=0.2). The inclusion of AMH improved the model (net reclassification index 0.10 [ 0.06 - 0.14); P<0.001). The instantaneous probability of conception was highest in cycle 4 across all AMH categories: the probability of natural conception was 11.2% (95% CI 9.0, 14.0) for low AMH, 14.3% (95% CI 12.3, 16.5) for normal AMH, and 15.7% (95%CI 12.9, 19.0) for high AMH. In the regular cycles sensitivity analysis (n=1,791), the low AMH group had a lower chance of conception (adjHR 0.77 95% CI 0.61, 0.97, p = 0.028) in the low AMH group compared to normal AMH, and similarly in the continuous model (adjHR 0.90; 95% CI 0.85-0.95, p<0.0001). ConclusionLow AMH levels (<1 ng/ml) are independently associated with a modest but significant reduction in the chance of conception.

Surgical management of an ectopic pregnancy in the setting of an unexpected Müllerian anomaly: intraoperative and postoperative implications

ObjectiveTo describe the intraoperative and postoperative implications arising from the unexpected diagnosis of a Müllerian anomaly during the surgical management of an ectopic pregnancy. DesignVideo article. SettingAcademic Center. Subject(s)A 39-year-old nulligravid woman with anovulation and irregular menstrual cycles presented to the office. Her urine pregnancy test was incidentally positive; serum β-human chorionic gonadotropin (β-hCG) level was 5,644 mIU/mL. Outpatient transvaginal ultrasonography (TVUS) demonstrated a 2.1 x 1.7 x 2.2-cm thick-walled structure in the left adnexa without an intrauterine pregnancy. These findings were highly suspicious for a left tubal ectopic pregnancy. The patient was consented for laparoscopy with planned left salpingectomy. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. InterventionDiagnostic laparoscopy did not show an obvious left tubal ectopic pregnancy. Instead, a right unicornuate uterus with a dilated rudimentary left uterine horn was seen. Both fallopian tubes and ovaries appeared normal. These laparoscopic findings were consistent with an ectopic pregnancy in the rudimentary horn. However, in the absence of informed consent for a hemi-hysterectomy and no evidence of ectopic rupture or bleeding within the pelvis, we decided to proceed with excision of the ectopic pregnancy from the uterine horn. An incision was made over the anterior surface of the uterine horn, and the pregnancy sac was dissected from the underlying myometrium and excised in its entirety. Left salpingectomy was also performed. The patient was discharged home the same day, and her β-hCG levels decreased to <5 mIU/mL within 28 days of surgery. Main Outcome MeasuresComplete resolution of a left rudimentary uterine horn ectopic pregnancy through surgical excision of the pregnancy sac without hemi-hysterectomy. ResultsPostoperative hysterosalpingography (HSG) demonstrated a right unicornuate uterus with normal fill and spill of the right fallopian tube. Magnetic resonance imaging (MRI) of the pelvis confirmed the findings of a right unicornuate uterus with a non-communicating left rudimentary uterine horn that did not contain any endometrial tissue. Thus, the patient did not require an interval hemihysterectomy. She underwent letrozole and intrauterine insemination treatment 5 months after the initial surgery, which resulted in a clinical intrauterine pregnancy. However, this pregnancy was terminated in the early second trimester due to findings of trisomy 18. She conceived naturally one year later, and this pregnancy resulted in a full-term vaginal birth at 39 weeks gestation. ConclusionUndiagnosed or unexpected Müllerian anomalies can impact the standard intraoperative and postoperative management of ectopic pregnancies.

Fortified Pregnancy: A Case Report of Heterotopic Gestation with A Successful Obstetrical Outcome

Heterotopic pregnancy is a rare condition when at least two pregnancies are present simultaneously at different implantation sites. Such cases may lead to devastating outcomes if nor properly handled. The index patient is a 38 year old Gravida 6 Para 4 (4014), who presented with severe hypogastric pain, pallor, amenorrhea with positive pregnancy test and a transvaginal ultrasound showing a strong consideration of heterotopic gestation. Emergency exploratory laparotomy for ruptured tubal pregnancy, Left salpingectomy, and evacuation of hemoperitoneum was done, with a bulbously enlarged left fallopian tube with a 2-cm point of rupture seen intraoperatively

Exploring acceptability, opportunities, and challenges of community-based home pregnancy testing for early antenatal care initiation in rural Kenya

BackgroundMany women in low- and middle-income countries, including Kenya, access antenatal care (ANC) late in pregnancy. Home pregnancy testing can enable women to detect pregnancy early, but it is not widely available. Our study explored the acceptability and potential of home pregnancy testing delivered by community health volunteers (CHV) on antenatal care initiation in rural Kenya.MethodsThis study was part of a public health intervention to improve uptake and quality of ANC. Between November and December 2020, we conducted 37 in-depth interviews involving women who tested positive or negative for a urine pregnancy test provided by CHVs; CHVs and their supervisors involved in the delivery of the pregnancy tests; facility healthcare workers; and key informants. Using Sekhon et al.‘s framework of acceptability, the interviews explored participants’ perceptions and experiences of home pregnancy testing, including acceptability, challenges, and perceived effects on early ANC uptake. Data were analysed thematically in NVivo12 software.ResultsHome pregnancy testing was well-received by women who trusted test results and appreciated the convenience and autonomy it offered. Adolescents cherished the privacy, preferring home testing to facility testing which could be a stigmatising experience. Testing enabled earlier pregnancy recognition and linkage to ANC as well as reproductive decision-making for those with undesired pregnancies. Community delivery of the test enhanced the reputation and visibility of the CHVs as credible primary care providers. CHVs in turn were motivated and confident to deliver home pregnancy testing and did not find it as an unnecessary burden; instead, they perceived it as a complement to their work in providing ANC in the community. Challenges identified included test shortages, confidentiality and safeguarding risks, and difficulties accessing facility-based care post-referral. Newly identified pregnant adolescents hesitated to seek ANC due to stigma, fear of reprimand, unwanted parental notification, and perceived pressure from healthcare workers to keep the pregnancy.ConclusionHome pregnancy testing by CHVs can improve early ANC initiation in resource-poor settings. Mitigating privacy, confidentiality, and safeguarding concerns is imperative. Additional support for women transitioning from pregnancy identification to ANC is essential to ensure appropriate care. Future research should focus on integrating home pregnancy testing into routine community health services.

Adnexal Torsion of a 28 cm Paratubal Cyst: A Case Report

Objective: To report a rare case of a 28 cm left adnexal torsion requiring surgical intervention including detorsion and salpingectomy Methods: Case report. Results: An 18-year-old nulliparous female with morbid obesity presented to the emergency department complaining of one week of sharp right lower quadrant pain with nausea and vomiting that had acutely worsened. Vital signs were notable for tachycardia, but otherwise within normal ranges. She had a significant leukocytosis. Her pregnancy test was negative. A CT abdomen/pelvis was obtained that demonstrated a large multiloculated complex cystic mass measuring 28.5 x 19.8 x 13.3 cm with possible origin from the ovaries that could represent a serous cystadenoma. Additionally, the scan was remarkable for a heterogeneous and enlarged left ovary measuring 7.6 x 5.9 x 7.2 cm, surrounded by free fluid and mesenteric edema. On examination, she did not demonstrate any surgical abdomen findings. Her pain improved with pain medication. She was admitted, tumor markers obtained, and an ultrasound ordered. The ultrasound demonstrated normal appearing right ovary with present doppler flow and a simple cyst measuring 6.6 x 5.1 x 6.1 cm. The left adnexa was noted to have a complex versus solid mass with unclear boundaries of the ovary. Also noted on the ultrasound were two large simple midline cysts measuring 10.5 x 9.1 x 11.8 cm inferiorly and 18.2 x 15.5 x 17.2 cm superiorly. No free fluid was seen within the right upper quadrant on ultrasound. The view of the left upper quadrant was suboptimal. Due to these findings, Gynecologic Oncology service was also consulted and after discussion, decision made to proceed urgently to diagnostic laparoscopy with robotic assisted cystectomy versus oophorectomy. Upon laparoscopic entry into the abdomen, a large necrotic-appearing left adnexal mass was visualized coming from the left fallopian tube. Both the left fallopian tube and left ovary were necrotic, with the left ovary being torsed numerous times. After resection of the large left fallopian tube and cyst, the left ovary was detorsed, and the decision was made to leave the ovary in situ. It still appeared necrotic, but its blood supply was intact. There was a large simple paratubal cyst on the right fallopian tube that was also drained and excised. Postoperatively, her right lower quadrant pain resolved, and she was discharged on post-operative day 1. She prescribed a two-week course of doxycycline and metronidazole as pelvic inflammatory disease could not be ruled out. At outpatient follow-up, she was asymptomatic and ready to begin working again. Her pathology report confirmed a large left paratubal cyst with associated findings of ischemia due to torsion and a large right paratubal cyst. Conclusions: Adnexal torsion is a rare gynecologic disorder caused by the partial or complete rotation of the ovary and/or the fallopian tube on its vascular support, which can negatively impact fertility. Prompt diagnosis is key, but definitive diagnosis is only by direct visualization. The differential diagnosis for acute onset of severe pelvic pain with nausea and vomiting is broad and includes ectopic pregnancy, pelvic inflammatory disease, endometriosis, ruptured ovarian cyst, urologic issues and gastrointestinal issues. Commonly, ultrasound is used to help evaluate a possible torsion with several classic findings that were not noted in this case, other than a mass. The two best known risk factors for adnexal torsion are a mobile ovarian mass and a history of prior torsion. Although large ovarian masses greater than 5 cm are more likely to cause torsion, some experts hypothesize that very large masses are less likely to torse given the constraints of the pelvis. However, such was not the case here. Additionally, it has been observed that adnexal torsion typically affects the right adnexa due to theoretical protection from the descending colon on the left. Given that the case presented did not have any of the typical imaging findings for adnexal torsion and that her pain was on the right but the torsion on the left, it is important to maintain a high level of suspicion when evaluating patients with acute onset pelvic pain of any location with nausea and vomiting.

Maternal and Neonatal Outcomes with One Abnormal Value on 100g Three Hour Glucose Tolerance Test in Pregnancy

Purpose: The primary objective of this study was to compare pregnancy outcomes for patients with no elevated glucose values, one elevated glucose value, and 2 or more elevated glucose values on the 3-hour glucose tolerance test (GTT). Methods: This was a retrospective chart review of obstetric patients seen by residents and attending physicians at a single institution from 2015 to 2020 who were required to complete a 3-hour glucose tolerance test (GTT). Data extracted from the maternal chart included demographic information, BMI, route of delivery, presence of preeclampsia, chorioamnionitis, shoulder dystocia and preterm labor. Data extracted from the neonatal chart included blood glucose level after birth, birth weight, Apgar scores, and if NICU admission was required. Continuous data were analyzed using one-way ANOVA to compare the 3 groups, followed by post-hoc Tukey HSD to compare the 1 abnormal value group to the control group. Dichotomous data were analyzed using Chi square tests. Logistic regression was performed using shoulder dystocia as the outcome. Results: Patients with two or more elevated GTT values had higher age and BMI and were more likely to be prescribed diabetic medications compared to those with normal or one elevated value. They were also more likely to deliver at an earlier gestational age. Patients with one elevated GTT value experienced a statistically significant higher chance of shoulder dystocia compared to patients with all normal GTT results (OR 2.34; 95% CI 1.05, 5.20). Patients with two or more elevated values were more likely to have preeclampsia and a neonate requiring NICU admission. There were no differences in cesarean delivery rate, hemorrhage or chorioamnionitis between the groups. Conclusions: Patients with one elevated GTT value are a special subset of patients who do not meet criteria for gestational diabetes, yet do not have normal glucose testing results. We hypothesize that this group is at higher risk of shoulder dystocia because these patients may have hyperglycemia but often do not receive the same type of monitoring, dietary education, medication initiation and induction timing as patients who meet criteria for gestational diabetes.

Coincidental discovery of HIV and pregnancy positive status in primary healthcare facilities.

HIV-positive and pregnancy diagnosis is a traumatic, shocking, and distressing experience for women. Adoption of routine HIV counselling and testing in the antenatal programme aimed to increase the uptake and the early diagnosis of HIV among pregnant women to prevent maternal HIV transmission to unborn babies and neonates. The study aimed to explore the psychological reaction of women coincidentally discovering their HIV-positive status and pregnancy while seeking medical care in primary healthcare facilities in the Tshwane district. Descriptive phenomenology involving a semi-structured in-depth interview was used to collect data. The sample was purposively selected. Twenty-eight women participated in the research project. Face-to-face in-depth audio recorded interviews were used to gain a full understanding of the experiences and feelings of the participants. Reason for the uptake of pregnancy and HIV testing, reactions upon discovering HIV and pregnancy-positive status, emotions arising from the pregnancy and HIV-positive diagnosis, understanding HIV infection in pregnancy, and transitions to acceptance and coping with the HIV-positive diagnosis were themes that emerged from this study. It is crucial that responsible healthcare workers consider this psychological imbalance during their offering of antenatal and postnatal care services so that the pregnant women living with HIV can accept and cope with the situation.Contribution:This study accounts to support other studies that offer intense counselling for women coincidentally discovering their positive HIV status and pregnancy. It is important to remedy the acceptance of the situation and to promote HIV prevention and family planning for women of childbearing age.

Cell-free DNA test for fetal chromosomal abnormalities in multiple pregnancies.

This study aimed to report the screening performance of cell-free DNA (cfDNA) testing for chromosomal abnormalities in twins, triplets, and vanishing twin pregnancies. Data were obtained from pregnant women with a multiple pregnancy or a vanishing twin pregnancy at ≥10 weeks' gestation who requested self-financed cfDNA testing between May 2015 and December 2021. Those that had positive screening results had diagnostic confirmatory procedures after counseling and consent. The performance of screening of the cfDNA test was determined by calculating confirmation rate and combined false-positive rate (cFPR). Data from 292 women were included after exclusion of those lost to follow-up, with no-result on cfDNA testing, or had reductions. Of the 292 pregnancies, 10 (3.4%) were triplets, including no cases of trisomy 21 and trisomy 18; 249 (85.3%) were twins, including 3 cases of trisomy 21 and no cases of trisomy 18 and 13; and 33 (11.3%) were vanishing twins, including 3 cases of trisomy 21 and 1 case of trisomy 18. The median (IQR) maternal age was 34 years (31-37). For triplet pregnancies, the initial no-result rate was 10.3% (95% confidence interval [CI] 3.6-26.4), all with results after redraw. For twin pregnancies, the initial no-result rate was 12.9% (95% CI 9.6-17.0), and the no-result rate after redraw was 1.6% (95% CI 0.7-3.6). For vanishing twins, there were no cases with no-result. All triplets had low-risk cfDNA results. The confirmation rate for trisomy 21 was 100% with a FPR at 0% due to the small number of positive cases for twins. For vanishing twins, one high-risk case for trisomy 21 and the only high-risk case for trisomy 18 were confirmed with a cFPR of 8.3% (n = 2/24; 95% CI 2.3-25.9). cfDNA testing in twin pregnancies has sufficient screening performance for trisomy 21 but the number of affected cases for other conditions is limited to draw any meaningful conclusion. The use of cfDNA testing in triplet pregnancies and vanishing twins remains an area for further research.

Iodide based electrochemical gold quantification method for lateral flow assays

The lateral flow assay (LFA) is an ideal technology for at-home medical diagnostic tests due to its ease of use, cost-effectiveness, and rapid results. Despite these advantages, only few LFAs, such as the pregnancy and COVID-19 tests, have been translated from the laboratory to the homes of patients. To date, the medical applicability of LFAs is limited by the fact that they only provide yes/no answers unless combined with optical readers that are too expensive for at-home applications. Furthermore, LFAs are unable to compete with the state-of-the-art technologies in centralized laboratories in terms of detection limits. To address those shortcomings, we have developed an electrochemical readout procedure to enable quantitative and sensitive LFAs. This technique is based on a voltage-triggered in-situ dissolution of gold nanoparticles, the conventional label used to visualize target-specific signals on the test line in LFAs. Following the dissolution, the amount of gold is measured by electroplating onto an electrode and subsequent electrochemical quantification of the deposited gold. The measured current has a low noise, which achieves superior detection limits compared to optical techniques where background light scattering is limiting the readout performance. In addition, the hardware for the readout was developed to demonstrate translatability towards low-cost electronics.

Levothyroxine may not adequately prepare hypothyroid women for controlled ovarian hyperstimulation

BackgroundThyroid axis dysregulation during controlled ovarian hyperstimulation (COH) is more pronounced in hypothyroid‐treated women. Whether or not this leads to compromised thyroid hormone levels within the ovarian follicular fluid is not known.AimsTo determine whether ovarian follicular thyroid hormone levels are compromised in adequately replaced hypothyroid women undergoing controlled ovarian hyperstimulation (COH), and/or influence cycle/pregnancy outcomes.Materials and MethodsProspective cohort study involving 46 euthyroid (anti‐thyroid peroxidase antibody negative) and 16 levothyroxine‐replaced women with baseline thyroid‐stimulating hormone (TSH) &lt;2.5 mIU/L attending their first COH cycle. Follicular fluid TSH, free triiodothyronine (T3) and free thyroxine (T4) were recorded at oocyte pick‐up. Serum levels were measured at: (i) baseline; (ii) human chorionic gonadotropin trigger day; and (iii) cycle conclusion. The number of mature oocytes retrieved, fertilisation, early pregnancy loss and live birth rates were compared.ResultsMedian serum TSH levels were similar at baseline (1.76 vs 1.24 mIU/L, P = 0.053), but free T3 levels were lower (4.5 vs 4.8 pmol/L, P = 0.029) in levothyroxine‐replaced compared to euthyroid women, with serum TSH levels increasing across ovarian stimulation (P = 0.006) into pregnancy testing (P = 0.030). Follicular fluid free T3 levels were lower in levothyroxine‐replaced women (median 4.3 vs 4.6 pmol/L, P = 0.032). Fertilisation rates were lower (52% vs 71%, P = 0.043) in women requiring levothyroxine replacement, but numbers of mature oocytes retrieved, early pregnancy loss and live births did not differ.ConclusionAdequately replaced hypothyroid women achieve lower ovarian follicular fluid free T3 levels and poorer fertilisation rates compared to euthyroid women undergoing COH. Optimising T3 levels may be pivotal in improving COH outcomes in hypothyroid women.

Antithrombin testing and treatment in pregnancy: Their real-world relationship to clinical outcomes

BackgroundAntithrombin (AT) deficiency is a severe thrombophilia associated with increased rates of maternal morbidity, mortality, and greater healthcare resource utilization during pregnancy and postpartum. MethodsTwo large U.S. healthcare databases were queried for women aged 15–44 with delivery-related encounters: Cerner Real-World Data (CRWD, 01/01/2000–12/31/2021) and Premier Healthcare Database (PHD, 01/01/2016–01/01/2019). Individuals receiving cardiopulmonary bypass were excluded. Three cohorts were created: 1) Individuals who had AT levels tested any time between 9-months pre- through 3-months post-delivery (CRWD Test Cohort); 2) individuals prescribed AT concentrate (ATc) within 1-year pre- or 1-year post-delivery in CRWD (CRWD Medication Cohort); and 3) the same criteria as 2) applied to PHD (PHD Medication Cohort). ResultsThere were 5411 individuals in the CRWD Test Cohort, 13 in the CRWD Medication Cohort and 38 in the PHD Medication Cohort. Demographic and baseline clinical characteristics were similar across cohorts. AT level testing occurred pre-delivery in 47.9 % of the CRWD Test Cohort and 23.1 % of the CRWD Medication Cohort. ATc was administered during the delivery hospitalization to 0.1 %, 23.1 % and 50.0 % of the CRWD Test, CRWD Medication, and PHD Medication Cohorts, respectively. Across cohorts, 5.4–7.9 % of individuals experienced thrombosis during the delivery-related encounter. Mean (SD) total costs for delivery through 1-year post-delivery were $190,894 ($276,893) with $123,763 ($177,122) of total costs related to abnormal coagulation. ConclusionOpportunities exist to enhance the care of pregnant individuals with low AT levels throughout pregnancy, aiming for optimal maternal outcomes.
