Abstract
OBJECTIVES Sonographic evaluation of the basilar artery is challenging, and a limited number of reports are available about the prenatal period, as manual positioning of probes is technically difficult. The objective of this study was to describe a sonographic transabdominal approach based on slowflow HD for screening of the basilar artery during the second trimester scan. METHODS A total of 49 women who were enrolled in a second trimester screening were included when the fetus was in the occipitoanterior position. Dopper screening of the cerebral artery was performed, which revealed the "Y" sign indicating the basilar trunk arising from two vertebral arteries in the axial oblique view when the probe was located around the junction of the vertebral processes and occipital bone and was superior to the first vertebral body, sloping slightly to the cephalic side. The Doppler ultrasound probe was placed perpendicular to the basilar artery. The flow direction was below the baseline, away from the probe in the basilar artery, consistent with a caudocephalic orientation. Peak systolic and diastolic velocities were measured. RESULTS The basilar artery was identified in all 49 fetuses, with a mean gestational age of 22 weeks (range 20 to 26 weeks). The mean peak systolic velocity of the basilar artery was 15.8 cm/second (range 9.12-26.44 cm/second). There was a slight increase in peak systolic velocity according to the gestational age of the fetus. CONCLUSIONS This study demonstrated that evaluation of the basilar artery can be performed during the second trimester via a new transabdominal approach involving slowflow HD.

Abstract
OBJECTIVE The aim of this study was address the challenges posed by the manual labeling of fetal ultrasound images by introducing an unsupervised approach, the fetal ultrasound semantic clustering (FUSC) method. The primary objective was to automatically cluster a large volume of ultrasound images into various fetal views, reducing or eliminating the need for labor-intensive manual labeling. METHODS The FUSC method was developed by using a substantial data set comprising 88,063 images. The methodology involves an unsupervised clustering approach to categorize ultrasound images into diverse fetal views. The method's effectiveness was further evaluated on an additional, unseen data set consisting of 8187 images. The evaluation included assessment of the clustering purity, and the entire process is detailed to provide insights into the method's performance. RESULTS The FUSC method exhibited notable success, achieving >92% clustering purity on the evaluation data set of 8187 images. The results signify the feasibility of automatically clustering fetal ultrasound images without relying on manual labeling. The study showcases the potential of this approach in handling a large volume of ultrasound scans encountered in clinical practice, with implications for improving efficiency and accuracy in fetal ultrasound imaging. CONCLUSION The findings of this investigation suggest that the FUSC method holds significant promise for the field of fetal ultrasound imaging. By automating the clustering of ultrasound images, this approach has the potential to reduce the manual labeling burden, making the process more efficient. The results pave the way for advanced automated labeling solutions, contributing to the enhancement of clinical practices in fetal ultrasound imaging.

Abstract
OBJECTIVE This study aimed to evaluate the differences in first-trimester and early-second-trimester transvaginal cervical length between patients with spontaneous preterm birth and those with term birth. DATA SOURCES PubMed, MEDLINE, Embase, and the Cochrane Library were systematically searched through August 2023. STUDY ELIGIBILITY CRITERIA Studies had to include (1) transvaginal cervical length measurement before 16+0 weeks of gestation and (2) transvaginal cervical length measurement in a population of patients who delivered preterm and at term. Abstracts, studies with duplicated data, and those with cervical length measured by transabdominal ultrasound scan were excluded. METHODS K.W.C. and J.L. searched for, screened, and reviewed the articles independently. The quality of the studies was assessed using the Newcastle-Ottawa scale. Mean differences were calculated using a random-effects model and pooled through a meta-analysis. RESULTS A total of 5727 published articles were identified. Only 10 studies (which analyzed 22,151 pregnancies) met the inclusion criteria. All studies excluded iatrogenic preterm birth. Transvaginal cervical length was significantly shorter in women with spontaneous preterm birth than in those who delivered at term (mean difference, -0.97; 95% confidence interval, -1.65 to -0.29; P=.005; I2=69%). When a linear technique was used to measure transvaginal cervical length, a significantly shorter transvaginal cervical length was associated with spontaneous preterm birth as opposed to term birth (mean difference, -1.09; 95% confidence interval, -1.96 to -0.21; P=.02; I2=77%). A shorter transvaginal cervical length measured by other techniques was also associated with spontaneous preterm birth before 34 to 35 weeks (mean difference, -1.87; 95% confidence interval, -3.04 to -0.70; P=.002; I2=0%). When studies where interventions were given for a "short" cervix or studies with a mean transvaginal cervical length ≥40 mm were excluded, a significantly shorter transvaginal cervical length was observed among those with spontaneous preterm birth (mean difference, -1.13; 95% confidence interval, -1.89 to -0.37; P=.004; mean difference, -0.86; 95% confidence interval, -1.67 to -0.04; P=.04; respectively). The optimal transvaginal cervical length cutoff was 38 to 39 mm, yielding pooled sensitivity of 0.80, specificity of 0.45, positive likelihood ratio of 1.16, negative likelihood ratio of 0.33, diagnostic odds ratio of 5.12, and an area under the curve of 0.75. CONCLUSION Women with spontaneous preterm birth had significantly shorter transvaginal cervical length before 16 weeks of gestation compared with those who delivered at term. The linear method and the 2-line method are acceptable techniques for measuring transvaginal cervical length.

Abstract
OBJECTIVE Currently, there are no established guidelines for obstetric ultrasound training at the core medical student clerkship level. Our objective was to develop practical, consensus-based learning objectives in second- and third-trimester ultrasound and assess the feasibility of implementing these objectives into a clinical curriculum. STUDY DESIGN Using the modified Delphi approach, a panel of expert stakeholders (n = 23) was assembled to reach consensus on the proposed learning objectives. A model curriculum was created consisting of a video tutorial, in-person training, and an optional tracker and piloted at two academic medical centers. Participant perception of acquired ultrasound skills and the program were assessed using a modified, previously validated survey. Pre- and postprogram survey responses were compared using the Chi-squared test of association. A p-value of <0.05 was considered statistically significant. RESULTS The expert panel reached consensus on five learning objectives to include determination of fetal number and presentation, assessment of fetal heart rate, determination of placental location, assessment of amniotic fluid volume, and a general understanding of the biophysical profile and its indications. A total of 26 students participated in the piloted curriculum. On completion, a majority of participants reported improved confidence in understanding and performing prenatal ultrasound in the second and third trimesters (p < 0.05). The majority of participants valued a hands-on ultrasound curriculum. CONCLUSION We propose practical, consensus-based learning objectives for second- and third-trimester sonography during the core clerkship with demonstrated feasibility in a two-center pilot program. KEY POINTS · Ultrasound is a valuable skill for medical students.. · Specific learning objectives in obstetric ultrasound are currently lacking.. · We propose consensus-based objectives and a model curriculum.. · A two-center pilot study demonstrated efficacy..

Abstract
INTRODUCTION Emergency cervical cerclage is a recognized method for preventing mid-trimester pregnancy loss and premature birth; however, its benefits remain controversial. This study aimed to establish preoperative models predicting preterm birth and gestational latency following emergency cervical cerclage in singleton pregnant patients with a high risk of preterm birth. MATERIAL AND METHODS We retrospectively reviewed data from patients who received emergency cerclage between 2015 and 2023 in three institutions. Patients were grouped into a derivation cohort (n = 141) and an independent validation cohort (n = 61). Univariate and multivariate logistic and Cox regression analyses were used to identify independent predictive variables and establish the models. Harrell's C-index, time-dependent receiver operating characteristic curves and areas under the curves, calibration curve, and decision curve analyses were performed to assess the models. RESULTS The models incorporated gestational weeks at cerclage placement, history of prior second-trimester loss and/or preterm birth, cervical dilation, and preoperative C-reactive protein level. The C-index of the model for predicting preterm birth before 28 weeks was 0.87 (95% CI: 0.82-0.93) in the derivation cohort and 0.82 (95% CI: 0.71-0.92) in the independent validation cohort; The C-index of the model for predicting gestational latency was 0.70 (95% CI: 0.66-0.75) and 0.78 (95% CI: 0.71-0.84), respectively. In the derivation set, the areas under the curves were 0.84, 0.81, and 0.84 for predicting 1-, 3- and 5-week pregnancy prolongation, respectively. The corresponding values for the external validation were 0.78, 0.78, and 0.79, respectively. Calibration curves showed a good homogeneity between the observed and predicted ongoing pregnant probabilities. Decision curve analyses revealed satisfactory clinical usefulness. CONCLUSIONS These novel models provide reliable and valuable prognostic predictions for patients undergoing emergency cerclage. The models can assist clinicians and patients in making personalized clinical decisions before opting for the cervical cerclage.

Abstract
OBJECTIVES The objective was to identify the fetal hippocampus and fornix using 2D and to measure the C-shaped length of fornix and hippocampus. METHODS This study was designed in cross-section. Healthy singleton and between 18 and 24 weeks of gestation pregnant women who applied to the perinatology outpatient clinic for second-level ultrasound scanning between December 2022 and February 2023 were included in the study. Patients were screened consecutively. Demographic information of the participants was obtained and an ultrasound scan was performed. The fetal fornix-hippocampus' length and hippocampal height were measured in the sagittal section. Data were presented as mean ± standard deviation, median (min, max), or number (percent). RESULTS A total of 92 patients were included in the study. Fetal fornix and hippocampus measurements were taken in % 97.8 (90/92) patients. The mean of the fetal fornix-hippocampus length and fetal hippocampus height of 90 patients were measured as 35.6 ± 3.0 and 4.7 ± 3.9, respectively. CONCLUSION Fetal fornix and hippocampus can be visualized in easily with two-dimensional ultrasound during anomaly scanning in the second trimester.

Abstract
OBJECTIVE To compare the outcomes of termination of pregnancy with live fetuses in the second trimester (14-28 weeks), using misoprostol 400 mcg intravaginal every 6 h, between women with previous cesarean section (PCS) and no previous cesarean section (no PCS). METHODS A comparative study was conducted on a prospective database of pregnancy termination in the second trimester, Chiang Mai university hospital. Inclusion criteria included: (1) singleton pregnancy; (2) gestational age between 14 and 28 weeks; and (3) pregnancy with a live fetus and medically indicated for termination. The participants were categorized into two groups; PCS and no PCS group. All were terminated using misoprostol 400 mcg intravaginal every 6 h. The main outcomes were induction to fetal delivery interval and success rate, defined as fetal delivery within 48 h. RESULTS A total of 238 women, including 80 PCS and 158 no PCS, were recruited. The success rate of fetal delivery within 48 h between both groups was not significantly different (91.3% vs. 93.0%; p-value 0.622). The induction to fetal delivery interval were not significantly different (1531 vs. 1279 min; p-value > 0.05). Gestational age was an independent factor for the success rate and required dosage of misoprostol. The rates of most adverse effects of misoprostol were similar. One case (1.3%) in the PCS group developed uterine rupture during termination, ending up with safe and successful surgical removal and uterine repair. CONCLUSION Intravaginal misoprostol is highly effective for second trimester termination of pregnancy with PCS and those with no PCS, with similar success rate and induction to fetal delivery interval. Gestational age was an independent factor for the success rate and required dosage of misoprostol. Uterine rupture could occur in 1.3% of PCS, implying that high precaution must be taken for early detection and proper management. SYNOPSIS Intravaginal misoprostol is highly effective for termination of second trimester pregnancy with a live fetus, with a comparable success rate between women with and without previous cesarean section, with a 1.3% risk of uterine rupture among women with previous cesarean section.

Abstract
OBJECTIVE The aim of this study was to quantify the likelihood of assessing all mandated fetal views during the second-trimester anatomy ultrasound prior to the proposed federal 20-week abortion ban. STUDY DESIGN Retrospective cohort study of a random sample of 1,983 patients undergoing anatomy ultrasound in 2017 at a tertiary referral center. The difference in proportion of incomplete anatomic surveys prior compared with after 20-week gestation was analyzed using X 2 and adjusted logistic regression; difference in mean days elapsed from anomaly diagnosis to termination tested using t-tests and survival analysis. RESULTS Incomplete views were more likely with initial ultrasound before 20 weeks (adjusted relative risk: 1.70; 95% confidence interval: 1.50-1.94); 43.5% versus 26.1% were incomplete before and after 20 weeks, respectively. Fetal structural anomalies were identified in 6.4% (n = 127/1,983) scans, with 38.0% (n = 49) identified at follow-up after initial scan was incomplete. 22.8% (n = 29) with an anomaly terminated. CONCLUSION A complete assessment of fetal views during an anatomy ultrasound prior to 20-week gestation is often not technically feasible. Legislation limiting abortion to this gestational age would greatly impact patient's ability to make informed choices about their pregnancies. KEY POINTS · It is often not technically possible to complete anatomy ultrasound prior to 20-week gestation.. · Often, anomalies are missed during early, incomplete anatomy ultrasounds.. · After the diagnosis of a structural anomaly, one in five chose to terminate the pregnancy..

Abstract
Previable and periviable rupture of membranes is associated with significant morbidity for the pregnant patient. For those who have a choice of options and undergo active management, it is not known how the risks of induction of labor compare with those for dilation and evacuation (D&E). We performed a retrospective cohort study of patients with rupture of membranes between 14 0/7 and 23 6/7 weeks of gestation who opted for active management. Adverse events (52.2% vs 16.9%, P <.01) and time to uterine evacuation greater than 24 hours (26.7% vs 9.6%, P =.01) were more common among patients undergoing induction of labor. In a multivariable regression, induction of labor was an independent risk factor for complications (odds ratio 5.70, 95% CI, 2.35-13.82) compared with D&E. Severe complications were rare across both groups (4.4% for patients undergoing induction vs 2.6% for D&E, P =.63). Given the differing risks by termination method, access to D&E is an important treatment option for this patient population.

Abstract
PURPOSE To compare the effectiveness of vaginal misoprostol for second-trimester termination between pregnancies with a dead fetus in utero and those with a live fetus and to identify factors associated with the success rate. METHODS Singleton pregnancies with live fetuses and dead fetuses, between 14 and 28 weeks of gestation, with an unfavorable cervix, were recruited to have pregnancy termination with intravaginal misoprostol 400 mcg every 6 h. RESULTS Misoprostol was highly effective for termination, with a low failure rate of 6.3%. The effectiveness was significantly higher in pregnancies with a dead fetus (log-rank test; p: 0.008), with a median delivery time of 11.2 vs. 16.7 h. Fetal viability, fetal weight or gestational age, and an initial Bishop score were significantly associated with the total amount of misoprostol dosage used for induction. Fetal viability and gestational age/fetal weight were still independent factors after adjustment for other co-factors on multivariate analysis. CONCLUSION Vaginal misoprostol is highly effective for second-trimester termination, with significantly higher effectiveness in pregnancies with a dead fetus. Also, the effectiveness is significantly associated with birth weight/gestational age, and initial Bishop score.

Abstract
Hemolysis, elevated liver enzyme levels, and low platelet count (HELLP) syndrome is one of the most severe complications of hypertensive disorders of pregnancy. HELLP syndrome occurring before 22 gestational weeks (GWs) is extremely rare, and patients prevalently exhibit underlying maternal diseases or fetal abnormalities. Here, we report the case of a pregnant woman who had HELLP syndrome at 20 GWs without any obvious underlying maternal diseases or fetal abnormalities. A 38-year-old pregnant woman was referred to Kobe University Hospital from another hospital at 19 + 5/7 GWs for hypertension, proteinuria, generalized edema, and fetal growth restriction. She was diagnosed with partial HELLP syndrome according to the Mississippi classification at 20 + 2/7 GWs. The patient was managed following the Mississippi protocol, including intravenous dexamethasone, magnesium sulfate, and antihypertensive drugs. She received intensive blood pressure and laboratory data monitoring using an arterial line and additional treatments, including platelet transfusion, intravenous haptoglobin infusion, and human atrial natriuretic peptide. The pregnancy ended in an induced delivery at 20 + 3/7 GWs, and she was discharged without complications 10 days postnatal. We performed laboratory tests for diagnosing underlying diseases but identified no obvious underlying diseases. This report indicates that early and intensive treatment of patients with HELLP syndrome occurring before 22 GWs according to the Mississippi protocol may enable clinicians to complete pregnancy termination without maternal complications and provide useful information to clinical practitioners in perinatal medicine.

Abstract
OBJECTIVES This study aimed to compare effectiveness and safety of cervical preparation with osmotic dilators plus same-day misoprostol or overnight mifepristone prior to dilation and evacuation (D&E). STUDY DESIGN We conducted a retrospective cohort analysis of 664 patients initiating abortion between 18 and 22 weeks at an ambulatory health center. We abstracted medical record data from two consecutive 12-month periods in 2017 to 2019. All patients received overnight dilators plus: 600 mcg buccal misoprostol 90 minutes before D&E (period 1); 200 mg oral mifepristone at time of dilators (period 2). Our primary outcome was procedure time. We report frequency of patients experiencing any acute complication, defined as unplanned procedure (i.e., reaspiration, cervical laceration repair, uterine balloon tamponade) or hospital transfer and bleeding complications. RESULTS We observed higher mean procedure time in the mifepristone group (9.7 ± 5.3 minutes vs 7.9 ± 4.4, p = 0.004). After adjusting for race, ethnicity, insurance, body mass index, parity, prior cesarean, prior uterine surgery, gestational age, provider, trainee participation, and long-acting reversible contraception initiation, the difference remained statistically significant (relative change 1.09, 95% CI 1.01, 1.17) but failed to reach our threshold for clinical significance. The use of additional misoprostol was more common in the mifepristone group, but the use of an additional set of dilators was not different between groups. Acute complications occurred at a frequency of 4.1% in misoprostol group and 4.3% in mifepristone group (p = 0.90). CONCLUSIONS We found procedure time to be longer with adjunctive mifepristone compared to misoprostol; however, this difference is unlikely to be clinically meaningful. Furthermore, the frequency of acute complications was similar between groups. IMPLICATIONS Overnight mifepristone at the time of cervical dilator placement is a safe and effective alternative to adjuvant same-day misoprostol for cervical preparation prior to D&E and may offer benefits for clinic flow and patient experience.

Abstract
INTRODUCTION The studies about effect of fetal anemia on placental and maternal molecular changes have rarely been published. This study aimed to compare oxidative stress levels and mitochondrial function in the placenta and maternal peripheral blood mononuclear cell (PMBCs) between anemic fetuses (using fetal Hb Bart's disease as a study model) and non-anemic fetuses. METHODS A cross-sectional study was conducted on pregnancies affected by Hb Bart's disease and non-anemic fetuses between 16 and 22 weeks of gestation. Placental tissue and maternal blood for PBMCs were collected after pregnancy termination for determination of oxidative stress and mitochondrial function. RESULTS A total of 18 pregnancies affected by Hb Bart's disease and 12 non-anemic fetuses were enrolled. Placental thickness was significantly greater (p-value <0.001) in the affected pregnancies, whereas all Doppler indices of uteroplacental blood flow were comparable. Mitochondrial dysfunction was significantly increased (p-value <0.001) in the placenta of the affected fetuses. In the mothers of affected fetuses, there was an increase in mitochondrial oxidative stress levels with a significant increase in mitochondrial dysfunction in isolated PBMCs (p-value <0.001). DISCUSSION In the presence of normal uteroplacental Doppler studies, fetal anemia can induce a significant increase in oxidative stress and mitochondrial dysfunction in the placentas and mothers. The findings support that the placenta can be a source of oxidative stress agents which are released into systemic circulation prior to development of maternal adverse outcomes, and may explain pathophysiology of subsequent preeclampsia in late gestation, as commonly seen in pregnancies affected by fetal Hb Bart's disease, if pregnancy is not terminated.

Abstract
OBJECTIVES To compare one-day versus two-day mifepristone-misoprostol interval in late second trimester medication abortion. STUDY DESIGN This retrospective cohort study was conducted at St. Paul's Hospital Millennium Medical College, in Ethiopia. Data were collected retrospectively and analysed with SPSS 23 using simple descriptive analysis, t-test, Chi-squared test, and regression analysis, as appropriate. P-value < 0.05 and adjusted odds ratio (AOR) with 95% CI were used to present results significance. RESULTS A total of 282 women who had medication abortion in the late second trimester (167 with one-day and 115 with two-day mifepristone-misoprostol intervals) at 20-28 weeks of gestation were analysed. Both median and mean induction to expulsion interval (I-E) were much higher in the one-day mifepristone-misoprostol (mife-miso) interval than in the two-day mife-miso interval group. The median (and mean) I-E in the one-day interval group was 24 hours (21.9+/-6.6 hours) compared to 12 hours (14.6+/-8.8 hours) in the two-day mife-miso interval group (p-value < 0.001). Expulsion rate within 12 hours of starting misoprostol was significantly higher in the two-day cohort than in the one-day cohort (73% vs 25.6%, p-value < 0.001, aOR = 19.08 95%, CI = 5.1-70.7). CONCLUSIONS For second trimester medication abortion at later gestation, a two-day mifepristone-to-misoprostol interval significantly reduces induction to expulsion time compared to a one-day interval. IMPLICATIONS Compared to one-day interval, administration of mifepristone two days prior to misoprostol initiation has a shorter interval of induction to expulsion and a higher rate of abortion completion within 12 hours of initiation of misoprostol during late second trimester medication abortion.

Abstract
OBJECTIVE To confirm the identity and assess the prevalence and evolution of the fluid-filled interhemispheric midline structure, thought to be the cavum veli interpositi (CVI), in fetuses at 11-14 weeks' gestation. METHODS This was a retrospective study of first-trimester ultrasound scans performed at a single center over 3 months. Inclusion criteria were singleton pregnancies at 11-14 weeks' gestation with known neonatal outcome. Five experts reviewed the images. Mixed-effects logistic regression and generalized estimating equations (GEE) were conducted to analyze the associations between the presence of the structure and variables including ultrasound approach (transabdominal vs transvaginal), maternal body mass index (BMI), gestational age, fetal crown-rump length (CRL) and biparietal diameter (BPD). Second-trimester ultrasound scans of the fetal central nervous system at 18-24 weeks' gestation were evaluated for the persistence of the CVI in fetuses in which the structure was observed in the first trimester. RESULTS Of the 223 cases reviewed, 104 were included, among which the CVI was observed in 25 (24%) cases. There was no statistically significant difference in CVI visualization between transabdominal and transvaginal ultrasound examinations. GEE showed significant associations between the presence of the fetal structure and CRL (odds ratio (OR) per 10-unit increase, 1.32; P < 0.0001) and BPD (OR per 10-unit increase, 1.88; P = 0.0011). Maternal BMI and gestational age showed no significant effect on the presence of the CVI. At second-trimester follow-up of the 25 fetuses in which the CVI was observed initially, 44% still showed a CVI, 32% exhibited a cavum vergae, 4% had both structures and 20% had neither. CONCLUSIONS Based on its anatomical location and, in some fetuses, its visualization as a distinct entity from the third ventricle, the identity of the interhemispheric midline structure in the suprathalamic region of the fetal brain between 11-14 weeks' gestation was confirmed as the CVI. The CVI and/or cavum vergae persisted into the second trimester in 80% of fetuses identified initially as having a CVI. Its presence is not linked to pathology, offering reassurance to practitioners and parents. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND Childhood depression is a major public health issue worldwide. Previous studies have linked both prenatal metal exposures and the gut microbiome to depression in children. However, few, if any, have studied their interacting effect in specific subgroups of children. OBJECTIVES Using an interpretable machine-learning method, this study investigates whether children with specific combinations of prenatal metals and childhood microbial signatures (cliques or groups of metals and microbes) were more likely to have higher depression scores at 9-11 years of age. METHODS We leveraged data from a well-characterized pediatric longitudinal birth cohort in Mexico City and its microbiome substudy (n = 112). Eleven metal exposures were measured in maternal whole blood samples in the second and third trimesters of pregnancy. The gut microbial abundances were measured at 9-11-year-olds using shotgun metagenomic sequencing. Depression symptoms were assessed using the Child Depression Index (CDI) t-scores at 9-11 years of age. We used Microbial and Chemical Exposure Analysis (MiCxA), which combines interpretable machine-learning into a regression framework to identify and estimate joint associations of metal-microbial cliques in specific subgroups. Analyses were adjusted for relevant covariates. RESULTS We identified a subgroup of children (11.6 % of the sample) characterized by a four-component metal-microbial clique that had a significantly high depression score (15.4 % higher than the rest) in late childhood. This metal-microbial clique consisted of high Zinc in the second trimester, low Cobalt in the third trimester, a high abundance of Bacteroides fragilis, a high abundance of Faecalibacterium prausnitzii. All combinations of cliques (two-, three-, and four-components) were significantly associated with increased log-transformed t-scored CDI (β = 0.14, 95%CI = [0.05,0.23], P < 0.01 for the four-component clique). SIGNIFICANCE This study offers a new approach to chemical-microbial analysis and a novel demonstration that children with specific gut microbiome cliques and metal exposures during pregnancy may have a higher likelihood of elevated depression scores.

Abstract
INTRODUCTION During pregnancy, many changes in the musculoskeletal system and pregnancy-related disorders affect posture and postural stability. Pregnancy-related pelvic girdle pain (PPGP) is a common disorder in pregnancy; the cause remains unknown. The purpose of the present study was to determine if PPGP affects static postural stability and its relation to the stage of pregnancy. METHODS Sixty-three pregnant women between the ages of 18 and 45 and between the 12th and 38th weeks of gestation were included in the study. They were divided into four groups according on the trimester and the presence of PPGP. Static balance was assessed using a force plate on firm and compliant surfaces with eyes open and closed. RESULTS Pregnant women with PPGP had significantly (p < 0.05) greater centre-of-pressure velocity and sway area compared to pregnant women without PPGP, especially in the third trimester of pregnancy. In the second trimester, only two significant differences in COP parameters were observed between pregnant women with and without PPGP. Pregnant women in the third trimester of pregnancy had significantly (p < 0.05) greater centre-of-pressure velocity and larger postural sway area compared to pregnant women in the second trimester of pregnancy, regardless of PPGP. DISCUSSION AND CONCLUSION Pregnant women with PPGP had poorer static stability when compared to pregnant women without pain, especially in the third trimester of pregnancy. The cause could be found in the poorer ability to stabilise the trunk and pelvis, poorer proprioception, and issues with automatic movement patterns.

Abstract
OBJECTIVES Our institution introduced universal vasa previa (VP) screening utilizing transabdominal ultrasound with color Doppler for all pregnancies at the second trimester anatomy scan. Our study sought to describe the clinical impact of this intervention. METHODS Radiology records from the 12 months pre- and post-intervention were queried for "vasa previa." Records included for analysis were those with a first-time diagnosis or discussion of VP at the anatomy scan. Cases were categorized by outcome: (Group 1) True VP, with subgroups A, unresolved by time of delivery and B, resolved by delivery; (Group 2) False positives; (Group 3) Possible VP without definitive diagnosis; and (Group 4) VP ruled out, for example, "no features of VP." Group size was expressed as a percentage of total anatomy scans during pre- or post-intervention periods respectively. Absolute and relative percent change were calculated for each group. RESULTS In the pre-intervention period, 1 case (0.36% of total scans) was categorized in Group 1A, 1 case (0.36%) in Group 3, and 7 cases (2.53%) in Group 4. In the post-intervention period, 2 cases (0.30%) were in Group 1A, 4 cases (0.61%) in Group 1B, 2 cases (0.30%) in Group 2, 1 case (0.15%) in Group 3, and 7 cases (1.06%) in Group 4. There was a +153% relative change in true positives, from 0.36 to 0.91%. CONCLUSIONS Universal color Doppler screening may have increased detection (sensitivity) while simultaneously increasing false positives (decreased specificity). While decreasing sensitivity is not ideal, this is acceptable given the potential catastrophic outcome of a missed VP.

Abstract
BACKGROUND Research reveals small and inconsistent findings linking prenatal tobacco exposure and early fetal growth, but failure to consider confounding and amount of exposure many explain inconsistencies. GOAL To examine whether fetal growth effects following exposure to tobacco are evident in the second trimester, specific to certain growth parameters, and dose dependent. METHODS Participants were pregnant women (64 smokers, 100 controls) with no other drug use. Available data included background/medical information and ultrasound measurements coded as percentiles. RESULTS Controlling for background differences, 10+ cig/day predicted a 10+ percentile point reduction in estimated fetal weight, femur length, head circumference, and biparietal diameter compared to non-exposed controls. Exposure to <10 cig/day predicted significant reduction in only biparietal diameter. Exposure was unrelated to abdominal circumference. CONCLUSIONS Results demonstrate utility of considering amount of exposure when examining/quantifying fetal growth effects, and suggest even reduction in early pregnancy smoking may positively benefit aspects of fetal development.

Abstract
INTRODUCTION Women with a prior stillbirth or a history of recurrent first trimester miscarriages are at increased risk of adverse pregnancy outcomes. However, little is known about the impact of a second trimester pregnancy loss on subsequent pregnancy outcome. This review investigated if second trimester miscarriage or termination for medical reason or fetal anomaly (TFMR/TOPFA) is associated with future adverse pregnancy outcomes. MATERIAL AND METHODS A systematic review of observational studies was conducted. Eligible studies included women with a history of a second trimester miscarriage or termination for medical reasons and their pregnancy outcomes in the subsequent pregnancy. Where comparative studies were identified, studies which compared subsequent pregnancy outcomes for women with and without a history of second trimester loss or TFMR/TOPFA were included. The primary outcome was livebirth, and secondary outcomes included: miscarriage (first and second trimester), termination of pregnancy, fetal growth restriction, cesarean section, preterm birth, pre-eclampsia, antepartum hemorrhage, stillbirth and neonatal death. Studies were excluded if exposure was nonmedical termination or if related to twins or higher multiple pregnancies. Electronic searches were conducted using the online databases (MEDLINE, Embase, PubMed and The Cochrane Library) and searches were last updated on June 16, 2023. Risk of bias was assessed using the Newcastle-Ottawa scale. Where possible, meta-analysis was undertaken. PROSPERO registration: CRD42023375033. RESULTS Ten studies were included, reporting on 12 004 subsequent pregnancies after a second trimester pregnancy miscarriage. No studies were found on outcomes after second trimester TFMR/TOPFA. Overall, available data were of "very low quality" using GRADE assessment. Meta-analysis of cohort studies generated estimated outcome frequencies for women with a previous second trimester loss as follows: live birth 81% (95% CI: 64-94), miscarriage 15% (95% CI: 4-30, preterm birth 13% [95% CI: 6-23]).The pooled odds ratio for preterm birth in subsequent pregnancy after second trimester loss in case-control studies was OR 4.52 (95% CI: 3.03-6.74). CONCLUSIONS Very low certainty evidence suggests there may be an increased risk of preterm birth in a subsequent pregnancy after a late miscarriage. However, evidence is limited. Larger, higher quality cohort studies are needed to investigate this potential association.

Abstract
It is recommended that pregnant women be physically active to promote maternal and child health. This study aimed to explore the prevalence of physical inactivity and its modifiable predictors in the three trimesters in Chinese pregnant women. Four hundred forty-four pregnant women completed the Pregnant Physical Activity Questionnaire in the first, second, and third trimesters. The prevalence of physical inactivity reached its highest (66.2%) in the first trimester and lowest (19.4%) in the second trimester. Pregnant women with inadequate physical activity knowledge and low self-efficacy were at higher risk for physical inactivity. Monitoring physical inactivity could be incorporated into antenatal care and start from the first trimester. Prenatal care professionals should take action to increase pregnant women's physical activity self-efficacy and knowledge to enhance their physical activity.

Abstract
High HBV DNA levels predispose to mother to child transmission (MTCT) of HBV. Early nucleotide analogue (NA) therapy can reduce HBV DNA and minimize MTCT. We analysed immune-metabolic profile in pregnant mothers who received NA from 2nd trimester compared with untreated mothers. In 2nd trimester, there was no difference in immune profiles between Gr.1 and Gr.2 but high viral load women had downregulated pyruvate, NAD+ metabolism but in 3rd trimester, Gr.1 had significant reduction in HBV-DNA, upregulated pyruvate and NAD with increased IFN-2αA, CD8Tcells, NK cells and decreased Tregs, IL15, IL18, IL29, TGFβ3 compared to Gr.2. In Gr.1, three eAg-ve women showed undetectable DNA and HBsAg. At delivery, Gr.1 showed no MTCT, with undetectable HBV DNA, HBsAg, high CD8 and NK cells in two women. We conclude, that starting NA from second trimester, reduces HBV load and MTCT, modulates NAD, induces immunity and suggest use of NA in early gestation in future trials.

Abstract
OBJECTIVE To evaluate perinatal and postnatal outcomes of fetuses with an isolated small head circumference (HC) on expert ultrasound examination in the second trimester for further recommendations in prenatal care. STUDY DESIGN In a retrospective cohort we included singleton-pregnancies with a fetal HC > -3.0 SD and ≤ -1.64 SD determined on expert ultrasound examination between 18 and 24 weeks of gestational age. Three subgroups were determined: "isolated small HC (ISHC)", "small HC plus abdominal circumference (AC) ≤ p10 (SHC+)" and "small HC plus AC ≤ p10 and Doppler abnormalities (SHC + D)". After ultrasound examination, genetic testing was sometimes offered and postnatally genetic tests were performed on indication. RESULTS We included 252 pregnancies: 109 ISHC, 104 SHC+, and 39 SHC + D. In the ISHC and SHC+ subgroup, 96 % of the fetuses were born alive and did not die neonatal. In the SH + D group this was only 38 %. In the SHC+ subgroup, less fetuses were delivered vaginal (non-instrumental) compared to the ISHC subgroup (61 % vs. 73 %, p < 0.01). In the ISHC and SHC+ subgroup s some fetuses were diagnosed with congenital defects (4 % vs. 10 %, p = 0.08) and with a genetic anomaly (6.4 % vs. 7.7 %, p = 0.13) after 24 weeks or postnatally. In SHC + D subgroups 5 % presented with congenital defects and 2.6 % with a genetic anomaly. CONCLUSION We conclude that fetuses with a small HC without structural anomalies on second trimester expert ultrasound require follow-up and special medical attention. We recommend differentiating between ISHC, SHC+, and SHC + D for prenatal counseling. Genetic testing and referral to a clinical geneticist should be considered.

Abstract
OBJECTIVE To describe associations among background determinants of physical activity, modifiable theoretical determinants of physical activity, and measures of physical activity during the second and third trimesters of pregnancy among Black women. DESIGN Longitudinal cohort. SETTING Medical center obstetric clinic. PARTICIPANTS Pregnant Black women (n = 40 in second trimester, n = 38 in third trimester) METHODS: We measured background determinants (demographic and pregnancy characteristics, discrimination, and neighborhood walkability) during the second trimester. We measured modifiable theoretical determinants (self-efficacy and social support) and physical activity using self-report and device measures during the second and third trimesters. We used paired t tests to determine differences in the modifiable theoretical determinants from the second trimester to third trimester and used Pearson correlations among background and modifiable determinants and physical activity measures during the second trimester. RESULTS Participants' physical activity levels were low during the second and third trimesters (32% and 22% met recommendation, respectively). We found no changes in self-efficacy or social support between trimesters and found no associations between these modifiable determinants and actual physical activity. We found a positive correlation between previous pregnancies and physical activity measured by devices, r(36) = .33, p = .048. Pregnancy-specific stress, r(38) = -.40, p = .013, was negatively correlated, and age, r(38) = .38, p = .017, was positively correlated with self-reported physical activity. CONCLUSIONS Low levels of physical activity during pregnancy coupled with the absence of an association with modifiable factors affecting pregnancy physical activity indicate a need to further examine the social, cultural, and environmental determinants of physical activity.

Abstract
AIM This study aimed to clarify the factors influencing preeclampsia (PE) development in nulliparous Japanese women and to develop a PE prediction model using second trimester sonographic and clinical data readily available to obstetricians. METHODS This historical cohort study examined the obstetric records of nulliparous women who delivered at Yamanashi Prefectural Central Hospital from January 2019 to May 2023. A model was constructed to predict the PE development rate, with a focus on 796 nulliparous women. The assessed outcome was PE, excluding superimposed PE. Data on maternal age, assisted reproductive technology, mean arterial pressure, uterine artery notching, and umbilical artery resistance index were extracted. Multivariable logistic regression analysis was conducted on these five factors. RESULTS The incidence of PE was 4.3% (34/796). Multivariable analysis indicated significant odds ratios for the association of PE with mean arterial pressure (adjusted odds ratio: 1.06, 95% confidence interval: 1.03-1.10) and uterine artery notching (adjusted odds ratio: 6.28, 95% confidence interval: 2.82-14.0) in nulliparous women. The PE prediction formula was established as follows: Probability of PE development (%) = (odds/1 + odds) × 100, odds = ex and x = -11.3 + 0.039 × maternal age (years) + 0.91 × assisted reproductive technology + 0.061 × mean arterial pressure (mmHg) + 1.84 × uterine artery notching + 1.84 × umbilical artery resistance index. The sensitivity and specificity of this model were 58.8% and 84.5%, respectively (area under the curve: 0.79). CONCLUSIONS This study is the first to provide a prediction formula targeting the Japanese population. Our specialized model for nulliparous women could guide obstetricians to educate women regarding the precise prospect of PE development.

Abstract
The relationship between gut microbiota products trimethylamine oxide (TMAO) and related metabolites including betaine, choline and L-carnitine and hypertensive disorders of pregnancy (HDP) is unclear. In order to examine whether plasma TMAO and related metabolites predict the risk of HDP, a nested case-control study was conducted in Chinese women based on a prospective cohort including 9447 participants. 387 pairs of pregnant women (n = 774) were matched and their plasma TMAO, betaine, choline, and L-carnitine at 16-20 gestational weeks were measured by liquid chromatography-mass spectrometry. Odds ratio (OR) and the 95% confidence interval (95% CI) were calculated using the conditional logistic regression, to examine the association between TMAO metabolites and HDP. The findings showed that higher plasma betaine (≥24.94 μmol/L) was associated with a decreased risk of HDP and its subtype gestational hypertension (GH), with adjusted ORs of 0.404 (95% CI: 0.226-0.721) and 0.293 (95% CI: 0.134-0.642), respectively. Higher betaine/choline ratio (>2.64) was associated with a lower risk of HDP and its subtype preeclampsia or chronic hypertension with superimposed preeclampsia (PE/CH-PE), with adjusted ORs of 0.554 (95% CI: 0.354-0.866) and 0.226 (95% CI: 0.080-0.634). Moreover, compared with traditional factors (TFs) model, the TMAO metabolites+ TFs model had a higher predictive ability for PE/CH-PE (all indexes P values < 0.0001). Therefore, it suggests that the detection of plasma betaine and choline in the early second trimester of pregnancy can better assess the risk of HDP.

Abstract
OBJECTIVE To determine whether trust in the provider and sociodemographics are associated with individual-level abortion stigma. METHODS We performed a cross sectional and exploratory study design using secondary analysis of a randomized trial that enrolled participants undergoing second trimester abortion. We collected baseline survey data from 70 trial participants to assess stigma (Individual Level of Abortion Stigma scale, ILAS; range 0-4), trust in provider (Trust in Physician scale; range 1-5), anxiety, depression, and sociodemographics. We performed multiple linear regression, for which ILAS score was the outcome of interest. Univariate associations were used to inform the regression model. RESULTS The mean abortion stigma score was at the low end of the ILAS at 1.21 (range 0.2-2.8, SD 0.66). Age, race, income, BMI, parity, gestational age at time of abortion, and reasons for ending the pregnancy were not significantly associated with the ILAS score. Higher trust in provider scores were (m 4.0, SD 0.49) and inversely related to the ILAS score, even after adjustment for confounders (β -0.02, CI -0.03 to -0.004, p = 0.013). Screening positive for anxiety or depression was associated with a higher ILAS score ((β 0.48, CI 0.10, 0.90, p = 0.015); (β = 0.27 CI -0.097, 0.643)), while cohabitation was associated with lower ILAS score (β -0.44, CI -0.82 to -0.57, p = 0.025). CONCLUSIONS Trust in an abortion provider, anxiety, depression, and cohabitation are associated with abortion stigma among people seeking second trimester abortion care. Interventions that improve trust in a provider may be an area of focus for addressing abortion stigma. Future research should confirm these findings in larger populations and across diverse locations and demographics and to conduct qualitative research to understand what patients perceive as trust-promoting behaviors and words during abortion encounters.

Abstract
Spontaneous uterine rupture before the onset of labour is rare in pregnancy especially before the third trimester. It is life threatening with devastating consequences to the mother and fetus. We report a case of spontaneous second trimester uterine rupture in a multipara with a previous uterine scar with the aim of creating awareness and sharing the challenges in diagnosis and management of this unusual complication of pregnancy. A 34-year-old woman with two previous deliveries presented at 16 weeks gestation with abdominal pain and vaginal bleeding of one day duration. At presentation, she was pale and in shock. There was generalized abdominal tenderness with guarding and rebound tenderness. At laparotomy, there was uterine rupture involving the lower segment with right lateral upward extension which was repaired. She remained stable at the follow up visit. In conclusion, Spontaneous uterine rupture of a previous caesarean section scar in the second trimester is rare. The diagnosis should be considered in a woman with previous caesarean section who experience an acute abdomen in the second trimester of pregnancy.

Abstract
Objective: To investigate the feasibility of expectant management of different degrees of vaginal fluid in pregnant women with premature rupture of membranes in the second trimester. Methods: A retrospective cohort study was conducted to collect 103 pregnant women who were diagnosed with premature rupture of membranes in the second trimester of pregnancy and insisted on continuing the pregnancy in Shanxi Bethune Hospital from July 2012 to July 2022. According to the degree of vaginal fluid, pregnant women were divided into rupture group (with typical vaginal fluid, 48 cases) and leakage group (without typical vaginal fluid, 55 cases). The rupture latency (the time from rupture of membranes to termination of pregnancy), gestational weeks of termination, indications and methods of termination of pregnancy, maternal infection related indicators and perinatal outcomes were compared between the two groups. Univariate regression model was used to analyze the correlation between different degrees of vaginal fluid in pregnant women with premature rupture of membranes and maternal and neonatal outcomes. Results: (1) Obstetric indicators: there was no significant difference in the gestational age of rupture of membranes between the two groups (P>0.05). However, the proportion of rupture latency >28 days in the leakage group was significantly higher than that in the rupture group [42% (23/55) vs 13% (6/48); χ2=33.673, P<0.001], and the incidence of pregnancy termination ≥28 weeks was significantly higher [47% (26/55) vs 19% (9/48); χ2=9.295, P=0.002]. (2) Indications and methods of termination: the incidence of progressive reduction of amniotic fluid as the indication for termination in the leakage group was significantly lower than that in the rupture group [22% (12/55) vs 42% (20/48); χ2=4.715, P=0.030], and the incidence of full-term termination in the leakage group was significantly higher than that in the rupture group [31% (17/55) vs 12% (6/48); χ2=5.008, P=0.025], while there were no significant differences in the indications of termination of pregnancy, including amniotic cavity infection, uterine contraction failure and fetal distress between the two groups (all P>0.05). The incidence of induced labor or spontaneous contraction in the leakage group was significantly lower than that in the rupture group [53% (29/55) vs 81% (39/48); χ2=9.295, P=0.002], while the cesarean section rate and vaginal delivery rate were similar between the two groups (both P>0.05). (3) Infection related indicators: the incidence of amniotic cavity infection in the leakage group was significantly higher than that in the rupture group [31% (17/55) vs 13% (6/48); χ2=4.003, P=0.045]. However, there were no significant differences in the elevation of inflammatory indicators, the positive rate of cervical secretion bacterial culture and the incidence of tissue chorioamnionitis between the two groups (all P>0.05). (4) Perinatal outcomes: the live birth rate in the leakage group was significantly higher than that in the rupture group [51% (28/55) vs 27% (13/48); χ2=5.119, P=0.024]. The proportion of live births with 1-minute Apgar score >7 in the leakage group was significantly higher than that in the rupture group [38% (21/55) vs 17% (8/48); χ2=4.850, P=0.028]. However, there were no significant differences in the birth weight of live births and the incidence of neonatal complications between the two groups (all P>0.05). (5) Univariate regression analysis showed that compared with the rupture group, the leakage group had a higher risk of pregnancy termination at ≥28 gestational weeks (RR=2.521, 95%CI: 1.314-4.838; P=0.002), amniotic infection (RR=2.473, 95%CI: 1.061-5.764; P=0.025), perinatal survival (RR=1.880, 95%CI: 1.104-3.199; P=0.014). Conclusion: Compared with pregnant women with typical vaginal fluid in the second trimester of premature rupture of membranes, expectant treatment for pregnant women with atypical vaginal fluid is more feasible, which could effectively prolong the gestational weeks and improve the perinatal live birth rate.

Abstract
BACKGROUND Previous research has indicated the inverse association between physical activity (PA) and gestational diabetes mellitus (GDM). However, the dose-response relationship currently remains undetermined. This study aims to explore the dose-response relationship between PA during the first and second trimesters of pregnancy and GDM risk. METHODS Studies on the relationship between PA during pregnancy and GDM risk published before April 25, 2023, were searched for in six databases. According to the inclusion and exclusion criteria, all literature was screened for eligibility. The Newcastle-Ottawa Scale (NOS) was used to assess risk of bias. Publication bias was examined using funnel plots, Begg's and Egger's tests, as well as trim-and-fill analysis. We harmonized exposure estimates of PA during pregnancy to the common unit of the metabolic equivalent of task (MET)-h/week. Restricted cubic splines were used to model the dose-response relationship. The criteria from the World Cancer Research Fund were used to assess the certainty of evidence across outcomes. All analyses were performed using Stata 15.1. RESULTS The results indicated that in contrast with the lowest level of PA, promoting the highest PA level lowers the risk of GDM by 36% (RR = 0.64, 95%CI: 0.53 ~ 0.78). We found a curvilinear dose-response association between PA during the first trimester and incident GDM (Pnonlinearity = 0.012). Compared to inactive pregnant women, for those who achieved the guidelines-suggested minimum level (10 MET-h/week) of PA during the first trimester, the GDM risk was decreased by 13% (RR = 0.87, 95%CI: 0.79 ~ 0.96). A linear relationship was found between PA during the second trimester and the GDM risk (Pnonlinearity = 0.276). The results with a restricted cubic spline model suggested that pregnant women who accumulate 10 MET-h/week have a 1% reduced risk of GDM compared to completely inactive individuals. Twice (20 MET-h/week) or a higher amount of PA (50 MET-h/week) contributed to further reductions in GDM risk. CONCLUSION There is a dose-response relationship between higher levels of PA in both the first and second trimesters and reduced risk of GDM; the relationship is stronger in the first trimester. Increasing PA during pregnancy can prevent the development of GDM. PROSPERO REGISTRATION NUMBER CRD42023420564.

Abstract
Maternal exposure to organophosphate esters (OPEs) has been linked to an increased risk of adverse birth outcomes. However, the impact of OPEs on childhood growth remains uncertain. This study assessed the associations between prenatal concentrations of OPE metabolites and the growth trajectory in early childhood. 212 singleton pregnant women were included in this study, and they were recruited between August 2014 and August 2016 in Wuhan, China. We measured the urinary concentrations of OPE metabolites during the 1st, 2nd, and 3rd trimesters. Standard deviation scores for weight and length were calculated for children at birth, 1, 6, 12, and 24 months. Trajectories of weight-for-age z-score (WAZ) and weight-for-length z-score (WLZ) were classified into four groups using group-based trajectory modeling. Trajectories of length-for-age z-score (LAZ) were classified into three groups with the same model. Then, we calculated odds ratios (ORs) and 95 % confidence interval (95%CI) using multinomial logistic regression to estimate increases in odds of different growth trajectories per doubling in OPE concentrations compared with moderate-stable trajectory. For average concentrations of OPE metabolites and growth trajectory, our results indicated that higher bis(2-butoxyethyl) phosphate, total aromatic OPE metabolites, and total OPE metabolites during pregnancy were associated with a higher likelihood of children falling into the low-stable and low-rising WAZ trajectory. Furthermore, compared to the moderate-stable LAZ trajectory, increased concentrations of 1-hydroxy-2-propyl bis(1-chloro-2-propyl) phosphate were linked to an elevated risk of a low-stable LAZ trajectory. Additionally, the 1st and 2nd trimesters may represent critical windows of heightened vulnerability to the effects of OPE metabolites on childhood growth. In conclusion, our study proves that prenatal exposure to OPE metabolites is inversely related to childhood growth. It is essential to conduct further research involving larger populations and to consider other compounds with known developmental toxicity to obtain more reliable and comprehensive results.

Abstract
BACKGROUND Uterine prolapse is a rare complication of pregnancy, and there is still no consensus on the choice of delivery method. METHODS The patient's reproductive history included an abortion and eutocic delivery of a girl weighing 3200 g; the current pregnancy was the third pregnancy. Her cervical region was outside the vaginal opening and was red in color, with evident enlargement (6 × 4 cm) and a broken surface. The cervical area also showed white discharge. According to her Transvaginal ultrasonography revealed a fetus in the uterine cavity at approximately 19 weeks of gestation. Gynecological examination revealed prolapse of both the anterior and posterior vaginal walls. Evaluation of the pelvic organ prolapse-Q scores showed that the patient had uterine prolapse at stage IV. RESULTS Vaginal delivery was performed smoothly after oral administration mifepristone and misoprostol tablets for a few days, obtaining a dead female fetus in cephalic, 25 cm in length. The cervix of the pregnant woman did not prolapse during the delivery. CONCLUSION For pregnancy with uterine prolapse and cervical incarceration, transvaginal delivery is a potential treatment option. Maintenance of cervical retraction and oral mifepristone administration with misoprostol tablets is crucial during this delivery. This treatment can minimize the risk of cervical lacerations and uterine rupture, helping surgeons to complete the operation successfully.

Abstract
OBJECTIVE Whether or not the effects of anemia in the early phase, while the fetuses attempts to increase cardiac output to meet oxygen requirement in peripheral organs, is detrimental to the fetal developing vital organs is little-known. The objective of this is to compare prenatal cardiovascular changes and post-abortal cellular damages in the myocardium as a pumping organ and the brain as a perfused organ between anemic fetuses (using fetal Hb Bart's disease as a study model) in pre-hydropic phase and non-anemic fetuses. METHODS Fetuses affected by Hb Bart's disease and non-anemic fetuses at 16-22 weeks were recruited to undergo comprehensive fetal echocardiography. Cord blood analysis was used to confirm the definite diagnosis of fetal Hb Bart's disease and normal fetuses. Fetal cardiac and brain tissues were collected shortly after pregnancy termination for the determination of oxidative stress and mitochondrial function, including mitochondrial ROS production and mitochondrial membrane changes. RESULTS A total of 18 fetuses affected by Hb Bart's disease and 13 non-anemic fetuses were recruited. The clinical characteristics of both groups were comparable. The affected fetuses showed a significant increase in cardiac dimensions, cardiac function, cardiac output and brain circulation without deteriorating cardiac contractility and preload. However, in the affected fetuses, mitochondrial dysfunction was clearly demonstrated in brain tissues and in the myocardium, as indicated by a significant increase in the membrane potential change (p-value < 0.001), and a significant increase in ROS production in brain tissues, with a trend to increase in myocardium. The findings indicated cellular damage in spite of good clinical compensation. CONCLUSION The new insight is that, in response to fetal anemia, fetal heart increases in size (dilatation) and function to increase cardiac output and blood flow velocity to provide adequate tissue perfusion, especially brain circulation. However, the myocardium and brain showed a significant increase in mitochondrial dysfunction, suggesting cellular damage secondary to anemic hypoxia. The compensatory increase in circulation could not completely prevent subtle brain and heart damage.

Abstract
OBJECTIVE To examine the association of serum connecting peptide (C-peptide) concentrations with gestational diabetes mellitus (GDM) risk among Chinese women. METHODS A nested case-control study was conducted on 436 reproductive-aged women, involving 218 GDM cases and 218 controls matched at 1:1 by maternal age, in Beijing, China between January 2016 and December 2017. Fasting serum C-peptide were successively determined at 10-14 and 15-20 weeks of gestation. Restricted cubic spline and logistic regression analyses were utilized, and receiver operating characteristic (ROC) curves were generated to evaluate the predictive capacity of C-peptide for GDM. RESULTS Fasting serum C-peptide concentrations exhibited a significant decrease from the initial to the subsequent trimester in females with normal glucose tolerance (NGT). For each 1 log ng/mL increase of fasting serum C-peptide during the first and second trimesters, GDM risk increased by 2.38-fold [odds ratio (OR): 2.38, 95% confidence intervals (95%CI): 1.33-4.40] and 3.07-fold (OR: 3.07, 95%CI: 1.49-6.62), respectively. The areas under the ROC curves for the first- and second-trimester C-peptide were 80.4% and 82.4%. CONCLUSION Our findings revealed a positive correlation between fasting serum C-peptide during the first and second trimesters and the risk of GDM or its subtypes, underscoring the potential of C-peptide as a predictor for GDM development.

Abstract
OBJECTIVES To investigate whether the induction-to-expulsion interval during second-trimester medication abortion in pregnancies complicated by anencephaly or other fetal anomalies is prolonged compared to pregnancies without fetal anomalies STUDY DESIGN: This was a retrospective cohort study of women who had second-trimester medication abortion at St. Paul's Hospital Millennium Medical College (Addis Ababa, Ethiopia). We assigned subjects to one of three groups based on fetal diagnosis: 1) anencephaly group, 2) other congenital anomaly group, and 3) no anomaly group. Data were collected by reviewing patients' charts. We used SPSS version 23 to analyze the data. Simple descriptive analysis and χ2 test were performed as appropriate. RESULTS A total of 303 women had second-trimester medication at 14-28 weeks, of which 58 had anencephaly, 19 had congenital anomalies other than anencephaly, and the remaining 226 had no fetal anomalies. The mean induction-to-expulsion interval was 18.4 hours in the anencephaly group versus 19.4 hours in the other congenital anomaly group versus 19.2 hours in those without anomaly (p-value = 0.924). The 24-hour nonexpulsion rate was also comparable among the groups, with 5.25% rate of nonexpulsion in the anencephaly group versus 15.8% in the other congenital anomaly group versus 11.15% in the no anomaly group (p-value = 0.594). In multivariable regression analysis after controlling for parity, the 24-hour nonexpulsion rate was not significantly different. CONCLUSIONS In this study, pregnancies undergoing second-trimester medication abortion for fetal anomalies had comparable induction-to-expulsion interval and 24-hour expulsion rates compared to those who had the same procedure for other or no anomalies. IMPLICATIONS Second-trimester medication abortion procedure length in pregnancies complicated by anencephaly is similar to those pregnancies without anomalies.

Abstract
BACKGROUND Idiopathic bleeding in the second trimester of pregnancy complicates <1% of all pregnancies. This pregnancy complication can be caused by alterations in local hemostasis in the decidua due to infection/inflammation in the choriodecidual niche. This condition is associated with intraamniotic inflammatory complications. Antibiotic therapy effectively reduces the intensity of intraamniotic inflammation in certain pregnancy pathologies. However, whether antibiotic administration can reduce the intensity of the intraamniotic inflammatory response or eradicate microorganisms in patients with idiopathic bleeding during the second trimester of pregnancy remains unclear. OBJECTIVE This study primarily aimed to determine whether antimicrobial agents can reduce the magnitude of intraamniotic inflammation in patients with idiopathic bleeding in the second trimester of pregnancy by assessing the concentration of interleukin-6 in the amniotic fluid before and after 7 days of antibiotic treatment. The secondary aim was to determine whether treatment with a combination of antibiotics altered the microbial load of Ureaplasma species DNA in amniotic fluid. STUDY DESIGN This retrospective cohort study included singleton-gestation patients with idiopathic bleeding between 15+0 and 27+6 weeks who underwent transabdominal amniocentesis at the time of admission. Follow-up amniocentesis was performed in a subset of patients unless abortion or delivery occurred earlier. Concentrations of interleukin-6 were measured in the amniotic fluid samples, and the presence of microbial invasion of the amniotic cavity was assessed using culture and molecular microbiological methods. Intraamniotic inflammation was defined as an interleukin-6 concentration ≥3000 pg/mL in the amniotic fluid samples. RESULTS A total of 36 patients with idiopathic bleeding in the second trimester of pregnancy were included. All the patients underwent initial amniocentesis. Patients with intraamniotic inflammation (n=25) were treated using a combination of antibiotics consisting of intravenous ceftriaxone, intravenous metronidazole, and peroral clarithromycin. The patients without intraamniotic inflammation (n=11) were treated expectantly. In total, 25 patients delivered 7 days after admission. All patients with intraamniotic inflammation at the initial amniocentesis who delivered after 7 days underwent follow-up amniocentesis. Treatment with antibiotics decreased the interleukin-6 concentration in the amniotic fluid at follow-up amniocentesis compared with that at the initial amniocentesis in patients with intraamniotic inflammation (median [interquartile range]: 3457 pg/mL [2493-13,203] vs 19,812 pg/mL [11,973-34,518]; P=.0001). Amniotic fluid samples with Ureaplasma species DNA had a lower microbial load at the time of follow-up amniocentesis compared with the initial amniocentesis (median [interquartile range]: 1.5×105 copies DNA/mL [1.3×105-1.7×105] vs 8.0×107 copies DNA/mL [6.7×106-1.6×108]; P=.02). CONCLUSION Antibiotic therapy was associated with reduced intraamniotic inflammation in patients with idiopathic bleeding in the second trimester complicated by intraamniotic inflammation. Moreover, antibiotic treatment has been associated with a reduction in the microbial load of Ureaplasma species DNA in the amniotic fluid.

Abstract
This is a case of a spontaneous haemoperitoneum occurring in the second trimester of pregnancy which was managed with interventional radiology to avoid laparotomy and its potential consequences. We aim to raise awareness of this condition in pregnancy because the perinatal mortality rate is as high as 36%. Spontaneous haemoperitoneum in pregnancy (SHiP) has frequently been associated with vascular rupture from pre-existing endometriosis. Most cases of SHiP have been managed with laparotomy. However, transcatheter embolisation can impart lifesaving alternatives to more invasive interventions when caring for pregnant patients. More judicious use of imaging procedures may also help improve diagnostic and therapeutic pathways with SHiP. We recommend that high-risk pregnancies are managed in level IV regional perinatal healthcare centres, when possible, where subspecialists and alternative measures of management exist.

Abstract
OBJECTIVES To compare transvaginal (TV) and trans-abdominal (TA) ultrasound assessment of cervical length (CL) at the time of the second-trimester scan for fetal anomalies. METHODS This was a prospective study including consecutive pregnant women attending the low-risk ultrasound clinic of two fetal medicine centres in Italy. The inclusion criteria were women between 19 + 0 and 22 + 0 weeks of gestation, attending the prenatal ultrasound clinic for the routine second trimester screening for fetal anomalies. The primary outcome was to compare the CL measurement obtained at TV compared to TA ultrasound; the secondary outcome was to report the inter and intra-observer variability of CL measured with the two different approaches. All women underwent TV and TA assessment of the cervix performed by two experienced certified operators, blinded to each other. Intra-class correlation coefficients (ICC) and Bland-Altman analyses were used to analyse the data. RESULTS Two hundred and fifty women were included in the analysis. All women had anteverted uterus. The mean gestational age at ultrasound was 20.7 ± 0.7 weeks; 1.2 % (3/250) scans were performed at 19 weeks, 49.2 % (123/250) at 20 weeks, 44.8 % (112/250) at 21 weeks and 4.8 % (12/250) at 22 weeks of gestations. Identification of the major landmarks of CL at TA ultrasound was achieved in all the included cases. There was good reliability between CL measured at TA (ICC 0.95, 95 % CI 0.93-0.97 for observer 1 and 0.92 %, 95 % CI 0.89-0.94 for observer 2) and TV ultrasound 0.97, 95 % CI 0.96-0.98 for observer 1 and 0.96, 95 % CI 0.95-0.97 for observer 2). There was also good reliability between the two observers for both the TA and TV assessment of the CL. Mean TA CL was 41.4 ± 5.5 for observer 1 and 40.5 ± 4.8 for observer 2 with no significant differences between the two measurements (mean difference 0.92 mm, 95 % CI -9.7 to 11.2). Likewise, there was no difference between the CL measured at TV ultrasound between the two observers (mean difference -0.83 mm, 95 % CI -5.97 to 4.30). Finally, there was no difference in the mean CL measured at TA compared to TV, either considering the overall population of women (mean difference: -0.43, 955 CI -8.65 to 7.79), or when stratifying the analysis according to the parity status and the operator. CONCLUSIONS Among experienced operators, there was no difference between TV and TA ultrasound assessment of the CL at the time of the routine anomaly scan for fetal anomaly.

Abstract
BACKGROUND Copper (Cu) is a physiologically important trace element during pregnancy. The study aim is to assess the altered level of serum Cu and its association with some metabolic indexes in Gestational Diabetes Mellitus (GDM). METHODS A total of 108 pregnant women (aged 18 - 40, second trimester) are included in the study and divided into two groups (GDM n = 54; pregnant with normal glucose tolerance (NGT), n = 54) after performing a 2-hour 75-g oral glucose tolerance test (OGTT). Maternal blood samples are collected at 26 - 28 gestational week. All biochemical parameters are measured in serum from fasting venous blood. Serum Cu levels are analyzed by flame atomic absorption spectrophotometry (Perkin Elmer AAnalyst 300, USA). Body Mass Index (BMI), insulin sensitivity/resistance, triglyceride-glucose (TyG), TyG-BMI (triglyceride glucose-body mass) indexes are calculated by formulas. RESULTS The following data were observed: significantly higher levels of serum Cu (p = 0.009), pre-pregnancy BMI (pre-pBMI), BMI at the GDM diagnosis (pBMI), TyG, pregnancy TyG-BMI (pTyG-BMI) p < 0.001, and triglycerides (Tgl) (p = 0.02) in GDM compared to NGT pregnancy. The study presents a positive correlation between serum Cu and pre-pBMI (p < 0.02), pBMI and pTyG-BMI (p < 0.001). Besides, pre-pBMI (mean ≥ 25 kg/m2), pBMI (mean ≥ 30 kg/m2), and pTyG-BMI are associated with 14.5% (OR 1.145, 95% CI: 1.064 - 1.232; p < 0.001), 15.3% (OR 1.153, 95% CI: 1.070 - 1.243; p < 0.001), and 5.9% (OR 1.059, 95% CI: 1.022 - 1.086; p < 0.001) increased risk for GDM development. No association is found between Cu and Tgl levels, fasting plasma glucose e(FPG) and TyG. ROC analysis suggests the serum Cu as a possible risk factor for GDM development. The analysis shows that at a cutoff point of ≥ 31.9 µmol/L, serum Cu presents a sensitivity and specificity of 64.8% and 66.7% in the prediction of GDM development (AUC = 0.659, p < 0.012). After adjustment for maternal age, gestational age, and family predisposition, the odds ratios (ORs) (95% CIs) still show association of Cu levels with increased GDM risk (OR 1.099, 95% CI 1.018 - 1.184, p = 0.013). CONCLUSIONS pTyG-BMI index exhibits a better interaction than TyG index, Tgl, and glucose separately with serum Cu levels where BMI has a mediator's role.

Abstract
BACKGROUND Asymptomatic isthmic contractions are a frequent physiological phenomenon in pregnancy, sometimes triggered by bladder voiding. They can interfere with proper cervical length assessment and may lead to false images of placenta previa. However, there is limited research on the prevalence and characteristics of these contractions. OBJECTIVE This study aimed to determine the prevalence and characteristics of isthmic contractions after bladder voiding in the second trimester of pregnancy, to evaluate their effect on cervical length assessment, and to propose a new method for the objective assessment of the presence and intensity of isthmic contractions. STUDY DESIGN In this prospective observational study, long videos of the uterine cervix were recorded in 30 singleton pregnancies during the second trimester of pregnancy after bladder voiding. Isthmic length and cervicoisthmic length changes were assessed over time. The isthmic length was measured using a new approach, which involved calculating the distance from the base of the cervix to the internal os, including the isthmus. RESULTS Isthmic contractions were observed in 43% of pregnant women (95% confidence interval, 26%-62%) after bladder voiding. The median time for complete isthmus relaxation was 19.7 minutes (95% confidence interval, 15.0 to not available). No substantial differences in maternal characteristics were found between individuals with and without contractions. The proposed method for measuring isthmic length provided an objective assessment of the presence and intensity of isthmic contractions. A cutoff of 18 mm in isthmic length allowed for the distinction of pregnant women presenting a contraction. In addition, the study identified a characteristic undulatory pattern in the relaxation of the isthmus in half of the cases with contractions. CONCLUSION Isthmic contractions are a common occurrence after bladder voiding in the second trimester of pregnancy and may interfere with proper cervical length assessment. We recommend performing cervical assessment at least 20 minutes after bladder voiding to reduce the risk of bias in cervical length measurement and to avoid false images of placenta previa. The new method for measuring isthmic length provides an objective way to assess the presence and intensity of isthmic contractions. Further research is needed to understand the role of isthmic contractions in the physiology of pregnancy and birth.
