1196-P: Offspring Being Overweight and Born Preterm Are More Common in Women Treated with Insulin Pump Compared with Multiple Daily Injections—A Large Prospective Cohort Study

Aims: Investigate glycemic control and risk of perinatal complications in women with type 1 diabetes (T1D) treated with insulin pump vs. multiple daily injections (MDI) during pregnancy. Methods: A secondary analysis of a prospective cohort of 2003 pregnant women. Odds ratios (OR) were estimated by logistic regression in crude and adjusted models for potential confounders. Results: In total, 723 women were treated with pump and 1280 were treated with MDI. At baseline (gestational weeks 8.6 (IQR: 7-10)) pump users had significant lower mean HbA1c (51.0 (10.2) mmol/mol (6.8 (0.9) %) vs. 54.2 (14.5) mmol/mol (7.1 (1.3) %), P < 0.001), longer diabetes duration (mean (SD) 18.3 (7.8) vs. 14.5 (8.3) years, p < 0.001) and higher prevalence of retinopathy (35.5% vs. 24.8%, p < 0.001). HbA1c in late pregnancy was similar (46.2 (9.4) mmol/mol (6.4 (0.9) %) vs. 46.4 (10.8) mmol/mol (6.4 (1.0) %), P=0.7458). Proportion of offspring being large for gestational age (LGA) was 59.0% (pump) vs. 52.2% (MDI) (adjusted OR 1.33 [95%CI 1.07;1.65], P=0.009) and born preterm 39.6% vs. 32.1% (adjusted OR 1.52 [95%CI 1.23;1.87], P=0.0001) (Table). No statistically significant difference was observed for other endpoints. Conclusion: Insulin pump treatment in pregnant women with T1D was associated with higher risk of LGA offspring and preterm delivery compared with MDI.

174-OR: Identification of Gestational Diabetes (GDM) Subtypes via Machine Learning and Associations with Perinatal Complications

There has been increasing recognition of GDM heterogeneity. We aimed to identify GDM subtypes using 45 variables from the electronic health records via Uniform Manifold Approximation and Projection and Density-Based Spatial Clustering of Applications with Noise, and assess associations with risk of perinatal complications via logistic regression. Since risk factors for GDM and complications were used to identify subtypes, association between subtypes and complications were not adjusted. In a cohort study of 37,561 racially and ethnically diverse individuals with GDM in 2011-2021, we split the sample into training/validation (70%/30%) sets. In the training set, 4 clusters (C) were identified. C1 (14.4%) and C2 (7.8%) were more likely to have early GDM diagnosed by Carpenter-Coustan criteria, pre-existing conditions (hypertension, prediabetes, polycystic ovary syndrome, and obesity), and to be older and multiparous, compared to C3 (65.7%) and C4 (12.1%; Table). Compared to C3 as the mildest and most common subtype, C2 and C4 had higher risk of preeclampsia/eclampsia, C2 had higher risk of placental abruption, and C1, C2, and C4 had higher risk of preterm birth, large for gestational age, and neonatal intensive care unit admission. Findings were confirmed in the validation set. Subtyping GDM may inform personalized risk assessment and management to improve perinatal outcomes. Disclosure Y.Zhu: None. R.Harvill: None.

Glycemic Control Trajectories and Risk of Perinatal Complications Among Individuals With Gestational Diabetes

ABSTRACT Approximately 8% of pregnancies in the United States are affected by gestational diabetes mellitus (GDM) per year. The condition is associated with higher risk of adverse perinatal outcomes, including hypertensive disorders of pregnancy, cesarean delivery (CD), macrosomia, shoulder dystocia, neonatal hypoglycemia, and adverse long-term outcomes, including diabetes and cardiovascular disease. Randomized clinical trials have suggested that glycemic control of GDM with medical nutritional and insulin therapies may improve perinatal outcomes. The American Diabetes Association recommends using self-monitoring of blood glucose (BG) to manage glycemic control during pregnancy. However, large-scale, population-based studies evaluating self-monitoring of BG are limited. In addition, the conventional model for glycemic control status using optimal versus suboptimal is insufficient to capture progressive changes during pregnancy. The aim of this study was to review whether glycemic control trajectories (GCTs) from GDM diagnosis to delivery are associated with the risk of perinatal complications. This was a population-based, cohort study of individuals with GDM who received prenatal care in an integrated health care delivery system between 2007 and 2017. Included were those diagnosed with GDM at 24 to 28 weeks of gestation. Excluded were those who had diabetes before pregnancy. Individuals were asked to self-monitor BG measurements to assess glycemic control 4 times per day at mealtimes. The measurements were collected by nurses or dietitians during weekly counseling calls. Optimal glycemic control was defined as <95 mg/dL for fasting and <140 mg/dL for 1 hour after lunch or dinner. Perinatal complications were the outcomes measured, including CD, preterm birth, shoulder dystocia, neonatal intensive care unit (NICU) admission, NICU stays ≥7 days, stillbirth, large-for-gestational age (LGA), and small-for-gestational age (SGA). To estimate associations between GCTs with the perinatal complications, multivariate Poisson regression models were used. A total of 26,774 individuals were included in the analysis. Four distinct GCTs were identified: trajectory 1 (T1) for stably optimal GCTs (39.3% of individuals), trajectory 2 (T2) for rapidly improving GCTs (34.9%), trajectory 3 (T3) for slowly improving to near-optimal GCTs (15.4%), and trajectory 4 (T4) for slowly improving to suboptimal GCTs (11%). For the T1 group, there were lower risks of CD (adjusted relative risk [aRR], 0.93; 95% confidence internal [CI], 0.89–0.96), shoulder dystocia (aRR, 0.75; 95% CI, 0.61–0.92), and NICU admission (aRR, 0.90; 95% CI, 0.83–0.97) compared with the T2 or reference group (P for trend <0.001), whereas for the T4 group there were higher risks of CD (aRR, 1.18; 95% CI, 1.12–1.24; P for trend <0.001), shoulder dystocia (aRR, 1.41; 95% CI, 1.12–1.78; P for trend <0.001), and NICU admission (aRR, 1.33; 95% CI, 1.20–1.47; P for trend <0.001). There was an increased risk of LGA across GCTs (from T1 [aRR, 0.74; 95% CI, 0.69–0.80] to T4 [aRR, 1.42; 95% CI, 1.31–1.53]; P for trend <0.001; vs T2), but there was a decreased trend of SGA (from T1 [aRR, 1.10; 95% CI, 1.02–1.20] to T4 [aRR, 0.63; 95% CI, 0.53–0.75]; P for trend <0.001). There was not a significant trend across GCTs for the risk of preterm birth and NICU stays ≥7 days. Overall, there was increasing risk of perinatal complications from T1 to T4 GCT, except for SGA. This study highlights the need for early GDM management to prevent perinatal complications.

Perinatalne komplikacije nakon ekscizionog lečenja cervikalne displazije

Cervical cancer is one of the most common malignant tumors in women. Mass screenings have significantly decreased its incidence, while causing an increase in precancerous cervical lesions that are mainly diagnosed in women of reproductive age who still have not fulfilled their reproductive goals. The aim of surgical treatment of these premalignant lesions is to prevent the development of cervical cancer, with minimal risks to the reproductive function. The most important perinatal complication is preterm delivery, usually coupled with preterm premature rupture of the membranes and chorioamnionitis. This results in prematurity with low birth weights, which can further result in increased neonatal morbidity and mortality. Data on the incidence of spontaneous miscarriages in treated women are non-consistent , however, it is believed that the incidence is higher in the second trimester. Possible predictors of complications are the amount of excised tissue, the type of excision technique, age at the time of surgery, and the length of the period between treatment and conception. Re-excision of the cervix is an additional risk factor for perinatal complications. The risk of perinatal complications is the highest after cold knife conization, followed by laser conization, whereas LEETZ excision means the lowest risk-this is primarily explained by the variations in the cone size. Having in mind that not all precancerous cervical lesions progress to cancer and that all types of excision treatments are associated with an increased incidence of perinatal complications, an adequate approach would entail primarily well-selected patients, i.e., treating only those women who are at real risk of developing cancer. The surgical treatment must be adapted to provide minimal risks for perinatal complications, maximal oncologic safety , and minimal risk of residual and/or recurring disease during a woman's lifespan.

ATYPICALPRESENTATION OF PREECLAMPSIA. ABOUT A CASE

3 to 5% of pregnancies are complicated by pre-eclampsia, which remains one of the main causes of fetal-maternal mortality and morbidity worldwide. The rate is higher in Morocco where the lack of prenatal consultation explains why pre-eclampsia is diagnosed at advanced stages. It is also responsible for 10 to 15% of maternal deaths in the Western world, and it remains the second leading cause of maternal death in France after the hemorrhage during delivery. Severe early pre-eclampsia (before 32 weeks of pregnancy) is associated with a risk of maternal mortality 20 times higher than after 37 weeks, and a higher risk of perinatal complications: prematurity, intrauterine growth retardation, premature detachment of the normoinsere placenta and perinatal mortality [3].Its pathophysiology is complex and multifactorial. The identification of biochemical and biophysical markers that point to placental and endothelial dysfunction allows us to improve our practices through new screening tests (4), which make it possible to target at-risk pregnancies, and to initiate treatment early. Currently, the coexistence of arterial hypertension, proteinuria and edema is arbitrary and inconstant. Preeclampsia can occurwithout the clinical data mentioned above or appear before the second half of pregnancy. Its symptoms are variable and reflect multisystem dysfunction [3]. Its development is unpredictable and can be overwhelming. The objective of this article is to report a case of atypical preeclampsia (before week 20 of gestation) associated with a HELLP Syndrome then to analyze the clinical features of atypical forms, differential diagnosis and progress in biochemical markers and biophysics that can aid in diagnosis.

Возможности применения молочной кислоты в акушерско-гинекологической практике

nflammatory diseases and dysbiosis provoked by opportunistic microbes currently rank first among lower reproductive tract infections in women. Lactobacilli are predominant in the vaginal microecosystem that is considered the first line of defense against infectious agents. Changes in hormonal profile, the pattern of intimate hygiene and sex life, and other factors impair the vaginal microecosystem. Diseases resulting from the activation of aerobic and anaerobic opportunistic microbes are particularly harmful during pregnancy, since they cause serious reproductive disorders and significantly increase the risks of perinatal complications. Frequent recurrences due to growing antibiotic resistance and the lack of potential antimicrobial treatment in the first trimester of pregnancy force to search for alternative therapeutic tools with good efficacy and safety. Topical agents containing lactic acid decrease vaginal pH and provide unfavorable conditions for the activity of opportunistic microbes, thereby maintaining the protective functions of Lactobacilli. Lactic acid is a natural chemical for this locus. As a result, agents containing this compound are virtually lacking side effects. They can be used along with antibiotics or as monotherapy.

Does interpregnancy BMI change affect the risk of complications in the second pregnancy? Analysis of pooled data from Aberdeen, Finland and Malta

ObjectiveWeight management interventions during pregnancy have had limited success in reducing the risk of pregnancy complications. Focus has now shifted to pre-pregnancy counselling to optimise body weight before subsequent conception. We aimed to assess the effect of interpregnancy body mass index (BMI) change on the risk of perinatal complications in the second pregnancy.MethodsA cohort study was performed using pooled maternity data from Aberdeen, Finland and Malta. Women with a BMI change of ±2 kg/m2 between their first and second pregnancies were compared with those who were BMI stable (remained within ±2 kg/m2). Outcomes assessed included pre-eclampsia (PE), intrauterine growth restriction (IUGR), preterm birth, birth weight, and stillbirth in the second pregnancy. We also assessed the effect of unit change in BMI for PE and IUGR. Logistic regression was used to calculate odds ratios with 95% confidence intervals.ResultsAn increase of ≥2 kg/m2 between the first two pregnancies increased the risk of PE (1.66 (1.49–1.86)) and high birthweight (>4000 g) (1.06 (1.03–1.10)). A reduction of ≥2 kg/m2 increased the chance of IUGR (1.15 (1.01–1.31)) and preterm birth (1.14 (1.01–1.30)), while reducing the risk of instrumental delivery (0.75 (0.68–0.85)) and high birthweight (0.93 (0.87–0.98)). Reducing BMI did not significantly decrease PE risk in women with obesity or those with previous PE. A history of PE or IUGR in the first pregnancy was the strongest predictor of recurrence independent of interpregnancy BMI change (5.75 (5.30–6.24) and (7.44 (6.71–8.25), respectively).ConclusionChanges in interpregnancy BMI have a modest impact on the risk of high birthweight, PE and IUGR in contrasting directions. However, a prior history of PE and IUGR is the dominant predictor of recurrence at second pregnancy.

P–397 Threatened Miscarriage and increase in Perinatal Morbidity

Abstract Study question Are women presenting with bleeding in the first trimester of pregnancy at a higher risk for perinatal complications later in pregnancy? Summary answer Women presenting with bleeding in the first trimester of pregnancy are more likely to experience perinatal and neonatal morbidity in pregnancy. What is known already Observational studies and a previously reported systematic review showed that women who experienced threatened miscarriage are more likely to have still birth, intra uterine growth restriction (IUGR), low birth weight, pre-eclampsia, placental abruption, placenta previa, preterm labour, preterm prelabour rupture of membrane, neonatal asphyxia and congenital anomalies in pregnancy. However, the evidence has been inconclusive and currently the women who experience threatened miscarriage receive low risk care. Study design, size, duration This was a prospective cohort study conducted on 298 women with threatened miscarriage (Cohort A) and 107 asymptomatic women (Cohort B). The women were recruited over a period of 18 months and were followed up for 9 months until delivery. Participants/materials, setting, methods Cohort A were women who presented with bleeding in the early pregnancy assessment unit and had a confirmed heartbeat on ultrasound scan between 6 weeks and 11 + 6 weeks of pregnancy and cohort B were women who were asymptomatic and booked with the community midwives as low risk. Both groups of women were followed up prospectively until delivery and data were collected on any perinatal outcomes and complications for both mother and the neonate. Main results and the role of chance The analysis showed that women who had bleeding in early pregnancy were more likely to have preterm delivery (RR 95% CI; 2.98 (1.07 – 8.27)); IUGR (unable to calculate the RR, as none of the women who continued their pregnancies beyond 24 weeks of gestation, developed IUGR in the asymptomatic control cohort. Nonetheless, IUGR occurred more frequently in the threatened miscarriage cohort than the asymptomatic cohort (P-value 0.02)); LBW (RR 95% CI; 6.14 (1.49 – 25.19), neonatal asphyxia (unable to calculate the RR, as none of the babies who were born to women in the asymptomatic control cohort develop neonatal asphyxia. Nonetheless, neonatal asphyxia occurred more frequently in the threatened miscarriage cohort than the asymptomatic cohort (P-value 0.02)). Preterm prelabour rupture of membrane was not significant with a P-value of 0.07. Limitations, reasons for caution The major limitation of this study was lower sample size and hence due to the rarity of many of the perinatal and neonatal outcomes, we were unable to calculate the relative risk. Wider implications of the findings: Current study agrees with the existing literature and reaffirms the association of perinatal and neonatal morbidities with threatened miscarriage and this group of women need to be managed as high-risk group antenatally.

Maternal Childhood Adversity as a Risk for Perinatal Complications and NICU Hospitalization.

To examine maternal childhood adversity in relation to increased risk for maternal and infant perinatal complications and newborn Neonatal Intensive Care Unit (NICU) admittance. A sample of 164 women recruited at their first prenatal appointment participated in a longitudinal study through 6 weeks postdelivery. Participants self-reported on their adverse childhood experiences (ACEs), negative health risks (overweight/obesity, smoking, and alcohol use), adverse infant outcomes, NICU admittance, and maternal perinatal complications across three pregnancy assessments and one post-birth assessment. Logistic binomial regression analyses were used to examine associations between maternal ACEs and adverse infant outcomes, NICU admittance, and maternal perinatal complications, controlling for pregnancy-related health risks. Findings showed that women with severe ACEs exposure (6+ ACEs) had 4 times the odds of reporting at least one adverse infant outcome (odds ratio [OR] = 4.33, 95% CI: 1.02-18.39), almost 9 times the odds of reporting a NICU admission (OR = 8.70, 95% CI: 1.34-56.65), and 4 times the odds of reporting at least one maternal perinatal outcome (OR = 4.37, 95% CI: 1.43-13.39). The findings demonstrate the extraordinary risk that mothers' ACEs pose for infant and maternal health outcomes over and above the associations with known maternal health risks during pregnancy, including overweight/obesity, smoking, and alcohol use. These results support a biological intergenerational transmission framework, which suggests that risk from maternal adversity is perpetuated in the next generation through biophysical and behavioral mechanisms during pregnancy that negatively affect infant health outcomes.

Intrapartum cesarean delivery and the risk of perinatal complications in women with and without a single prior cesarean delivery.

To determine maternal and neonatal complications associated with an intrapartum cesarean delivery (CD) with and without a history of a previous CD. A retrospective cohort study of all women who underwent an unplanned intrapartum CD following a trial of labor in a university-affiliated tertiary hospital, between 2009 and 2016. Perinatal outcomes of women with and without a history of a previous CD were compared. Composite adverse maternal outcome included one or more of the following: postpartum hemorrhage, need for blood transfusion, or cesarean hysterectomy. Composite adverse neonatal outcome included one or more of the following: 5-min Apgar score <7, neonatal seizure, need for intubation, meconium-aspiration-syndrome, or hypoxic-ischemic encephalopathy. During the study period, 42275 women attempted vaginal delivery. Of them, 2229 (5.3%) women underwent an unplanned intrapartum CD and met inclusion criteria: 337 (15.1%) with (study group) and 1892 (84.9%) without (control group) a previous CD. Women without a previous CD were younger and were characterized by higher rates of nulliparity and induction of labor compared with women with a previous CD. Other demographic and obstetrical characteristics did not differ between the groups. Indications for CD were also comparable between the groups. Uterine rupture complicated 2.3% of trials of labor among women with a previous CD. Adverse maternal (2.7% vs 2.9%, P=1.0) and neonatal (3.9% vs 4.3%, P=0.88) outcomes were comparable between the groups. After adjusting for potential confounders, a previous CD was not associated independently with adverse maternal outcomes (adjusted odds ratio [aOR] 0.86, 95% confidence interval [CI] 0.31-2.38; P=0.78) or neonatal outcomes (aOR 0.79, 95% CI 0.36-1.75; P=0.56). Our study provides evidence that perinatal outcomes of intrapartum CD delivery among women with a previous CD do not differ from those in women without a previous CD. These findings might improve the consultation and informed decision-making process for couples considering a trial of labor after CD.

COMPARATIVE ANALYSIS OF THE NEONATE BIRTH WEIGHT IN DIFFERENT TYPES OF TIN PREGNANCY

The relevance of the study lies in the significant increase in multiple pregnancies connected with the higher risk of perinatal complications, the controversy over the effects of chorionicity and sex of the babies on their birth weight, the need for timely diagnosis of fetal growth restriction, and associated morbidity.&#x0D; The objective of this study was to compare fetal weights at the birth of different variants of twins depending on chorionicity, gestational age, and sex.&#x0D; Materials and methods. During 2016-2020, 440 pairs of twins were examined: 375 dichorionic diamniotic and 65 monochorionic diamniotic (38 – boys, 27 – girls). Among dichorionic couples there were 186 (49.6%) opposite-sex, 98 (26.1%) same-sex males and 91 (24.3%) same-sex females. Fetal weight was measured at birth, and its relationship to chorionicity, fetal sex, a combination of same-sex or opposite-sex co-twins, and gestational age was assessed.&#x0D; Results. The average weight of 750 fetuses from dichorionic pairs (2570.0 ± 506.43 g) significantly exceeded the weight of 130 fetuses from monochorionic pairs (2333.4 ± 567.24 g, p &lt; 0.0001). The same-sex male (2603.8 ± 532.29 g) and opposite-sex dichorionic diamniotic (2595.6 ± 490.17 g). twins’ masses significantly surpassed the mass of all other twins (p &lt;0.05). In the group of dichorionic twins, the weight of boys exceeded the weight of girls (2638.1 ± 525.96 g vs. 2499.4 ± 475.84 g, p = 0.0002). This pattern was observed both inside the opposite-sex pairs (2674.2 ± 518.17 g vs. 2517.1 ± 448.24 g, p = 0.0019), and same-sex couples of boys compared to same-sex couples of girls (2603.8 ± 532.29 g and 2481.4 ± 503.08 g, respectively, p = 0.0224). No significant difference in the weight of girls of opposite-sex twins compared to same-sex couples was seen. In monochorionic pairs, the weight of male and female fetuses did not differ significantly. Birth weight discordance was found in all types of twins, the highest percentage of discordance was registered in monochorionic boys – 23.7%, second place in frequency took male dichorionic twins – 20.4%. Among the 30 discordant dichorionic opposite-sex twins in 19 (63.3%) cases, the male fetus was heavier. There was no significant difference in fetal weight when women were fertilized naturally and using assisted reproductive technologies. The average weight of children born by surrogate mothers exceeded the weight of children born by non-surrogate mothers (p = 0.0466). In the first pregnancy, children were born with a lower body weight compared to children born as a result of repeated pregnancies and in women who had a history of childbirth.&#x0D; Conclusion. The average weight of the fetuses of dichorionic twins was higher than the weight of the neonates f monochorionic pairs. The prevalence of the weight of boys over the weight of girls from dichorionic pairs and the absence of sex difference in fetal weight in monochorionic twins indicates the possibility of different functional activity of the placenta in fetuses of different sexes. Small for gestational age newborns were most often found in the group of female monochorionic twins and opposite-sex dichorionic pairs. Discordance of fetal mass was most common in monochorionic same-sex male twins. In discordant opposite-sex couples, the male fetus more often was heavier. There was no significant difference in newborn weight when women were fertilized naturally and with the use of assisted reproductive technologies. The average weight of surrogate-born children exceeded the weight of children born by non-surrogate mothers. In the first pregnancy, children were born with a lower body weight compared to children of multiparous and multigravida women.

Association of vitamin D receptor gene polymorphisms with gestational diabetes mellitus-a case control study in Wuhan, China

BackgroundGestational diabetes mellitus (GDM) increased risk of perinatal complications for both the women and the fetuses. The association between the vitamin D receptor (VDR) gene polymorphism and GDM has not been thoroughly investigated in Chinese pregnant women. Therefore, we aimed to determine whether VDR gene single nucleotide polymorphisms (SNPs) rs154410, rs7975232, rs731236, rs2228570 and rs739837 contribute to GDM risk in Wuhan, China. Moreover, we aimed to explore their combined effects on the risk of GDM.MethodsPregnant women who had prenatal examinations at 24 to 28 weeks’ gestation in our hospital from January 15, 2018 to March 31, 2019 were included in this case-control study. After exclusion, a total of 1684 pregnant women (826 GDM patients and 858 non-diabetic controls) were recruited. The clinical information and blood samples were collected by trained interviewers and nurses. Genotyping of candidate SNPs was conducted on the Sequenom MassARRAY platform. Statistical analyses including t-test, ANOVA, chi-square test and logistic regression were performed to the data with SPSS Software to evaluate differences in genotype distribution and associations with GDM risk. Multifactor dimensionality reduction method was used to explore the gene-gene interactions on the risk of GDM.ResultsDifferences in age, pre-pregnancy BMI, family history of diabetes and previous history of GDM between the case and control groups were statistically significant (P < 0.05), whereas no significant differences were found in height, gravidity, parity, and age of menarche (P > 0.05). There were no significant differences at genotype distributions of the examined VDR gene SNPs (P > 0.05). After adjusting by age, pre-pregnancy BMI, family history of diabetes, the results of logistic regression analysis showed no associations of the five SNPs with GDM in all the four genotype models(P > 0.05). Furthermore, there were no gene-gene interactions on the GDM risk among the five examined VDR gene SNPs.ConclusionsThe VDR gene SNPs rs154410, rs7975232, rs731236, rs2228570 and rs739837 showed neither significant associations nor gene-gene interactions with GDM in Wuhan, China.

1387-P: Risk of Perinatal Complications across Gestational Blood Pressure Levels in Women with and without Gestational Diabetes (GDM)

Hypertensive disorders in pregnancy and GDM are among the leading causes of maternal and perinatal morbidity. In 2017, the American College of Cardiology/American Heart Association released a new guideline for hypertension: systolic/diastolic blood pressure (SBP/DBP) ≥130/80 vs. previous 140/90 mmHg. However, these new cut-points have not been applied to pregnant women due to the lack of evidence on its impact on perinatal outcomes. We examined in women with and without GDM whether the risk of perinatal complications increased across SBP/DBP levels: normal (&amp;lt;120/80 mmHg, untreated), elevated (120-129/&amp;lt;80, untreated), stage 1 gestational hypertension (GH, 130-139/80-89, untreated), and stage 2 GH (≥140/90, treated or untreated). The study was conducted in 2017-2018 among 6458 women with GDM and 50885 without GDM, who were Kaiser Permanente Northern California members without pre-existing hypertension. Logistic regression examined associations of BP categories with perinatal outcomes, adjusting for sociodemographic, medical, and lifestyle covariates. The prevalences were higher in women with vs. without GDM: elevated BP 21.3% vs. 20.0%, stage 1 GH 18.6 % vs. 16.1%, and stage 2 GH 3.6% vs. 2.6% (all P &amp;lt;0.05). Associations with risk of large-for-gestational age were more pronounced among women with vs. without GDM, with adjusted odds ratios (OR) for elevated BP of 1.54 (95% CI 1.28-1.84) vs. 1.22 (1.13-1.31) and for stage 1 GH of 1.35 (1.11-1.64) vs. 1.21 (1.11-1.31) (P for interaction &amp;lt;0.01). Associations with preterm birth and small-for-gestational age were present only for stage 2 GH among women without GDM: OR 1.56 (1.26-1.91) and 1.59 (1.34-1.88), respectively (P for interaction=0.02 and 0.08, respectively). Although GH was more common in women with GDM, its associations with perinatal complications varied by GDM status. Also, our findings suggest the new guideline may identify women with subclinical high BP in pregnancy at risk of perinatal complications. Disclosure Y. Zhu: None. J. Feng: None. A. Ngo: None. C.

Возможности прогнозирования плацента-ассоциированной патологии во втором триместре беременности с помощью шкалы балльной оценки риска и кардиотокографии плода

Objective. Рreclinical prognosis of placental pathology (PP) during the second trimester of pregnancy using a new risk assessment scale and fetal cardiotocography (CTG). Patients and methods. This retrospective study included 264 patients who had undergone risk assessment during the first trimester of pregnancy using the conventional scale followed by reassessment on weeks 12–15 using the new scale. There were 102 women with PP and 162 women with normal pregnancy and delivery. We also performed prospective analysis of CTG results obtained during the second trimester. Results. The calculation of the risk for perinatal complications during the first trimester using the conventional scale demonstrated that 31% of women had PP. After recalculating the risks in the beginning of the second trimester, we found that 90% of women had PP; there was a threefold increase in the accuracy of prognosis. Women with pathological variants of CTG and risk of PP were 1.34 times more likely to have delayed fetal growth, 1.8 times more likely to develop preeclampsia, 2.6 times more likely to have preterm birth, 1.2 times more likely to have gestational hypertension, and 1.75 times more likely to have neonatal morbidity compared to women at risk of PP, but with normal CTG variants during the second trimester. Conclusion. Combination of the new risk assessment scale and CTG during the second trimester helps to identify women at risk of gestational pathology and to find and optimal tactics of their management.

Abstract 215: Risk Factors, Management, and Outcomes Among Pregnant Women with Atrial Fibrillation

Background: Atrial fibrillation and atrial flutter (AF) during pregnancy may confer increased risk of perinatal complications, particularly since pregnancy is a known hypercoagulable and arrhythmogenic state. However, few studies of outcomes among this population exist, and the optimal management strategy is unclear. We sought to determine the risk of adverse outcomes among pregnant women with AF. Methods: In this single-center study, patients with documented AF in pregnancy (1/1998-9/2018) were retrospectively analyzed. Charts were manually reviewed for demographics, comorbidities, underlying cardiac disease, and medications. Outcomes included arrhythmias, need for cardioversion, and thromboembolic events. Results: Of 66 pregnant women with documented AF, 20 (30.3%) had a diagnosis of AF prior to pregnancy and 46 (69.6%) had new onset AF during pregnancy or immediately postpartum (within six weeks of delivery). Nine women (13.6%) had persistent AF. Thirty women (45.4%) had valve disease and/or congenital heart disease and/or preexisting cardiomyopathy, and eight (12.1%) had AF precipitated by active infection or severe nausea/vomiting. Comorbidities included diabetes mellitus (3%), hypertension (9%), thyroid disease (13.6%), and obesity (32.6%). Electrical cardioversion was performed in 10 women before or after pregnancy, and five women underwent electrical cardioversion during their first or second trimesters of pregnancy. Rate-controlling medications were prescribed in 75.7%, with the most common medication being metoprolol (39.3%). Anticoagulation strategies varied from no intervention (53%), low-dose aspirin monotherapy (18.2%), enoxaparin (13.6%), warfarin (13.6%), or warfarin plus aspirin (3%). AF with rapid rate occurred during labor/delivery in 6/44 (13.6%) women with available telemetry data. One woman had a stroke during pregnancy related to vertebral artery dissection; she was in sinus rhythm at presentation. No other thromboembolic complications occurred. Conclusion: Pregnant women with AF may require rate-controlling medication and/or cardioversion during pregnancy, but appear to be at low risk for thromboembolic complications when appropriately anticoagulated. Larger studies of pregnant women both with and without underlying structural heart disease are needed to further assess complications and thromboembolic risk to optimize management of AF in pregnancy.

Splenic cyst as a rare cause of fetal abdominal cystic mass: A multicenter series of nine cases and review of the literature.

Congenital splenic cysts are a rare cause of abdominal cystic masses in the fetus. We describe nine cases of this condition, the largest reported experience to date. A review of the literature for similar cases was also performed. Cases of congenital splenic cyst were collected from three prenatal diagnostic centers and from a dedicated website of prenatal diagnosis. Information regarding clinical and sonographic findings was obtained by reviewing ultrasound reports and medical records. An electronic search of the Pubmed/MEDLINE database for similar cases, with subsequent manual cross-referencing, was performed and the relevant information from the articles was retrieved. A total of nine cases were added to the currently existing literature of 32 cases. In all but one of our cases, the prenatal detection of the splenic cyst was made in the third trimester, with a median gestational age at diagnosis of 30 weeks (range 22-37). The splenic cyst was confirmed after delivery in all but one case, which was lost to follow up. Postnatal sonographic examinations performed in the remaining eight cases showed that the cyst increased in size in two (25%), was stable in size in one (12%), decreased in size in one (12%), and completely regressed in the other four cases (50%). No complications associated with the cysts were reported in the infants. Congenital splenic cyst appears to be a benign condition with no known risk of perinatal complications. Nevertheless, differential diagnosis with other fetal cystic masses of the left upper abdominal quadrant and postnatal sonographic follow up to monitor the size of the cyst are important issues to be considered in the perinatal management of these cases.

Features of pregnancy with gestational diabetes mellitus and prediction of diabetic fetopathy

Gestational diabetes mellitus (GDM) and its consequences for the mother and child represent a serious not only medical, but also an economic problem. The urgency of studying this problem also lies in the fact that the number of pregnant women suffering from this disease is progressively increasing. The aim of the study was to study the risk factors and features of the course of pregnancy and childbirth in women with gestational diabetes mellitus, as well as to improve methods for diagnosing and predicting the development of diabetic fetopathy (DF). The work was carried out in 3 stages: 1 — prospective study of the course of pregnancy and childbirth in 104 women with GDM and in 50 pregnant women without GDM (control group); 2 — determination in the peripheral blood of the pregnant women of both groups of the level of glycemia, C-peptide, insulin, calculation of the insulin resistance index (HOMA-IR) with an assessment of the prognostic significance of these markers in the development of diabetic fetopathy; 3 — prediction of the development of diabetic fetopathy using a mathematical model that includes risk factors, the results of laboratory and instrumental research methods for this pathology. It was found that the violation of carbohydrate metabolism during pregnancy promotes the development of a large number of obstetric complications and in 36.5% of cases leads to the birth of children with diabetic fetopathy, which is manifested to a greater degree by macrosomia (30%), which increases the risk of perinatal complications and worsens the course of the period newborn in the future. An increase in the level of C-peptide was diagnosed in 87% of pregnant women with gestational diabetes, and an increase in the insulin resistance index in 93%, in contrast to the control group, where these indicators were 4 and 6%, respectively (p &lt; 0.05). Using discriminant analysis, it was determined that the threshold for predicting the development of DF should be considered an increase in HOMA-IR above 7 with a confidence of 73%, but the level of C- peptide does not have a predictive value. The mathematical model, including risk factors, data of laboratory and instrumental methods for studying carbohydrate metabolism in the mother and fetus, created using regression analysis, reflects the probability of development of diabetic fetopathy in pregnant women with gestational diabetes with an accuracy of 91.4%, which will help to prevent this complication in at an earlier stage through insulin therapy.

Intrapartum fever and the risk for perinatal complications – the effect of fever duration and positive cultures

Objective: To estimate the association between intrapartum fever and adverse perinatal outcome.Methods: A retrospective cohort study of women attempting vaginal delivery at term in a tertiary hospital (2012–2015). Perinatal outcome of deliveries complicated by intrapartum fever (≥38.0 °C) were compared to women with no intrapartum fever matched by parity and gestational age at delivery in a 1:2 ratio. Maternal outcome included cesarean section (CS), operative vaginal delivery (OVD), retained placenta or post-partum hemorrhage. Neonatal outcome included 5-minute Apgar score <7, umbilical artery pH <7.1, meconium aspiration syndrome, need for mechanical ventilation or hypoxic ischemic encephalopathy.Results: Overall, 309 women had intrapartum fever and 618 served as controls. Women with intrapartum fever had higher rates of OVD (34.3 versus 19.6%, p < .001) and CS (20.7 versus 8.7%, p < .001). In multivariate analysis, intrapartum fever was independently associated with adverse maternal (3.75, 95%CI 2.65–5.30, p < .001) and neonatal outcome (3.39, 95%CI 1.78–6.45, p < .001). In febrile women, fever duration was related to maternal complications, specifically to CS. In addition, maternal bacteremia and positive placental cultures were risk factors for neonatal complications compared to those with negative cultures (23.3 versus 9.8%, p = .01).Conclusions: Intrapartum fever was associated with adverse perinatal complications. The duration of intrapartum fever, maternal bacteremia, and positive cultures further increase this risk.
