Prior pregnancy complications and maternal cardiovascular disease in young Korean women within 10 years after pregnancy.

BACKGROUND: This study aimed to compare obstetric outcomes in Korean women with and without future cardiovascular disease (CVD) within 10 years after pregnancy, and assessed whether pregnancy complications are independent risk factors, and whether the combination of pregnancy complications has an additive function for risk factors for CVD. METHODS: This was a nationwide population-based study combining the database of the Korea National Health Insurance claims and National Health Screening Programs to assess preeclampsia, low birth weight (LBW), and preterm delivery as risk factors for CVD. Cox proportional hazards models was used to evaluate the risk of total CVD, ischemic heart disease (IHD), and stroke after the pregnancy complications, with adjustment for potential confounding variables. RESULTS: Women with CVD were likely to have a higher prevalence of pregnancy complications than women without CVD. The risk of total CVD was associated with preeclampsia (adjusted hazard ratio (HR), 1.60 [95% confidence interval (CI) 1.50-1.72]), LBW (1.20 [1.12-1.28]), and preterm delivery (1.32 [1.22-1.42]), after adjustment for confounders, including cardiovascular risk factors before pregnancy. The risk estimates of pregnancy complications for IHD were higher than those for stroke. In this study, the risk of total CVD was higher in the combined presence of preeclampsia and preterm delivery (2.23 [1.57-3.17] or all three complications (2.06 [1.76-2.40]), relative to no complications. The highest HR was noted in the risk of all pregnancy complications for IHD (2.39 [1.98-2.89]). CONCLUSION: Preeclampsia, preterm delivery, and LBW were independently associated with CVD in young Korean women. In addition, the combination of pregnancy complications had less-than-additive effects on CVD incidence.

Reliability of strain elastography using in vivo compression in the assessment of the uterine cervix during pregnancy.

Objective To determine the reproducibility of the mean strain value in various cervical areas and new elastographic parameters for measuring cervical stiffness evaluated by strain elastography using in vivo compression generated by internal organ movement. Methods A prospective observational study (140 singleton pregnant women; 15-33 weeks of gestation) was performed at two tertiary centers. Cervical strain was evaluated using E-cervix™ elastography. The mean strain levels of various cervical areas [internal os (IOS), external os (EOS) and endocervical area] and several new parameters [i.e. the ratio of the strain level of IOS and EOS, elasticity contrast index (ECI), and hardness ratio] were assessed twice by two independent examiners. The inter-observer and intra-observer variances were calculated using the intraclass correlation coefficient (ICC) with a 95% confidence interval (CI). Bland-Altman (B-A) analysis was also performed. Results The median gestational age was 24.0 weeks, and the mean cervical length (CL) was 3.8 cm. The intra-observer and inter-observer ICCs of the mean strain levels of the specified cervical area and new elastographic parameters were statistically significant (P < 0.001, all); the intra-observer ICC was 0.639-0.725, and the inter-observer ICC was 0.538-0.718. Conclusion The reproducibility of elastographic parameter measurements using in vivo compression is improvable.

Higher parity and risk of metabolic syndrome in Korean postmenopausal women: Korea National Health and Nutrition Examination Survey 2010-2012.

AIM: We sought to examine whether parity is associated with higher incidence of metabolic syndrome in postmenopausal women. METHODS: We conducted a cross-sectional study on 4098 Korean postmenopausal women by using nationally representative data from the Korea National Health and Nutrition Examination Survey 2010-2012. Multivariate logistic regression was performed to evaluate the relationship between parity and metabolic syndrome, with adjustment for potential confounding variables. RESULTS: The rate of metabolic syndrome was significantly higher with increasing number of parity, with dose-response relationship in univariate analysis (P <0.001). In addition, higher parity (≥3 live births) was associated with more prevalence of all components of metabolic syndrome compared with two live births (parity 2 vs 3 vs ≥4: 5.5 vs 12.1 and 14.4%, respectively; P < 0.001). However, after adjusting for demographic, socioeconomic, lifestyle and reproductive factors, we found that only higher parity was significantly associated with metabolic syndrome compared with two live births, and failed to show a dose-dependent relationship (parity 2 vs 3 vs ≥4: odds ratio 1 vs 1.404 vs 1.379, respectively; P = 0.043). We also proved that among the components of metabolic syndrome, only waist circumference had a significant positive relationship with parity in a multivariable adjusted model (parity 2 vs 3 vs ≥4: odds ratio 1 vs 1.559 vs 1.656, respectively; P < 0.001). CONCLUSION: Higher parity was independently associated with a higher risk of metabolic syndrome in postmenopausal women.

Mirror Syndrome Associated with 18p Deletion Syndrome.

BACKGROUND: Mirror syndrome is defined as the development of maternal edema in association with fetal hydrops. This rare disease is called mirror syndrome due to the presence of maternal edema that "mirrors" the fetal and placental condition. CASE: We report the first case of mirror syndrome associated with 18p deletion. CONCLUSION: Cytogenetic analysis should be considered in mirror syndrome to identify the underlying cause.

Contribution of Magnetic Resonance Imaging to Ultrasound for the Evaluation of Fetal Central Nervous System Anomalies.

OBJECTIVE: To evaluate whether magnetic resonance imaging (MRI) contributes to ultrasound for the evaluation of fetal central nervous system (CNS) anomalies. The secondary objective was to investigate whether MRI adds more information regarding the evaluation of specific pathologies or conditions. STUDY DESIGN: We retrospectively compared fetal MRI findings with ultrasound findings in CNS anomalies with respect to certain pathologic groups. Additionally, we evaluated diagnostic accuracy by comparing fetal MRI and ultrasound findings with postnatal findings. RESULTS: A total of 34 patients had 40 provisional diagnoses by fetal ultrasound, and of those patients 14 had a provisional diagnosis of ventriculomegaly and 14 had a provisional diagnosis of cerebellar or posterior fossa anomalies. MRI added to or changed the diagnosis in 52.5% of the patients with CNS abnormalities. The contribution rate in ventriculomegaly was 71.4%, and MRI changed the diagnosis in all indefinite diagnoses by ultrasound. Additionally, of the 15 patients with postnatal findings, there were no cases in which only the ultrasound findings were correct, but the MRI findings were incorrect. CONCLUSION: MRI contributes to ultrasound in the diagnosis of CNS anomalies. Cases of indefinite diagnosis and ventriculomegaly by ultrasound had greater benefit from MRI.

Progesterone Inhibits Leptin-Induced Invasiveness of BeWo Cells.

BACKGROUND: This study investigated the roles of progesterone and leptin in placenta invasion, which is closely related to pregnancy prognosis. We examined the effects of leptin and progesterone on the invasion of BeWo cells, a human trophoblastic cell line, and the effect of concurrent treatment. METHODS: Cells were treated with leptin (0, 5, 50, or 500 ng/mL) or progesterone (0, 2, 20, or 200 µM) and cultured in an invasion assay. Cells treated with 500 ng/mL leptin were also treated with progesterone (0, 2, 20, or 200 µM) in the invasion assay for 48 h. The number of cells that invaded the lower surface was counted in five randomly chosen fields using a light microscope with a 200× objective. The mRNA expression levels of MMP-9, TIMP1, TIMP2, and E-cadherin were detected by semi-quantitative PCR. RESULTS: Invasion of BeWo cells was promoted by leptin and influenced by both leptin concentration and treatment duration. Invasion was most effective at 500 ng/mL leptin and 48 h culture. Leptin-induced invasiveness was suppressed by progesterone in a dose-dependent manner. Leptin significantly decreased the expression levels of TIMP1 and E-cadherin, whereas progesterone significantly decreased expression of MMP-9 and significantly increased levels of TIMP1, TIMP2, and E-cadherin. CONCLUSIONS: Leptin promotes invasion of BeWo cells, and progesterone suppresses leptin-induced invasion by regulating the expressions of MMP-9, TIMP1, TIMP2, and E-cadherin. The balance between leptin and progesterone may play an important role in human placenta formation during early pregnancy.

Sonographic Parameters for Prediction of Miscarriage: Role of 3-Dimensional Volume Measurement.

OBJECTIVES: To evaluate the value of volume measurement using 3-dimensional sonography for prediction of miscarriage. METHODS: We prospectively enrolled 188 singleton pregnant women at 5 to 9 weeks' gestation. The 3-dimensional sonographic gestational sac volume and yolk sac volume were measured together with the fetal heart rate, gestational sac diameter, and yolk sac diameter. For each sonographic parameter, nomograms were created; z scores were calculated for each measurement, and the values were compared between miscarriage and ongoing pregnancy groups. Sonographic parameters for prediction of miscarriage were evaluated by multivariate analysis, and the screening performance was assessed by a receiver operating characteristic curve. RESULTS: Among the 188 pregnancies, 30 (16.0%) had miscarriage. Multivariate analysis showed that fetal heart rate below the 5th percentile (odds ratio, 6.43), gestational sac diameter below the 5th percentile (odds ratio, 4.87), gestational sac volume below the 5th percentile (odds ratio, 5.25), and yolk sac diameter below the 2.5th or above the 97.5th percentile (odds ratio, 15.86) were significant predictors of miscarriage (P = .018; P = .018; P = .033; and P < .001, respectively). At a false-positive rate of 30%, the detection rate for miscarriage in screening by a combination of fetal heart rate, gestational sac diameter, gestational sac volume, and yolk sac diameter was 77.8%. CONCLUSIONS: A small-for-gestational-age gestational sac volume is a significant sonographic predictor of miscarriage, as are fetal bradycardia, a small gestational sac diameter, and a small or large yolk sac diameter.

A misdiagnosed cause of chronic pelvic pain: abscess with foreign body.

OBJECTIVE: Chronic pelvic pain may present a diagnostic challenge. SETTING: Academic tertiary care center. DESIGN: Case report. CASE REPORT: A 46-year-old woman presented with pain on micturition and a 15-month history of right-sided pelvic pain aggravated by an abdominal massage. Her course and outcome, aided by use of computed tomography (CT) scan, is described, identifying a 6-cm, mass-like lesion in the right lower quadrant enclosing an ambiguous linear calcified lesion, which on laparotomy revealed a fish bone embedded in a section of the terminal ileum and the perivesical area. CONCLUSION: Chronic pelvic pain refractory to treatment merits consideration of CT to examine for foreign body.

Obstructive sleep apnea screening and perinatal outcomes in Korean pregnant women.

PURPOSE: This study was intended to evaluate the attributable risk of obstructive sleep apnea (OSA) by a sleep questionnaire to adverse pregnancy outcomes. METHODS: This was a prospective, cohort study in Korean pregnant women. Berlin questionnaire was employed for symptom-based OSA screening during the third trimester and obstetric outcome data were obtained in 276 deliveries. The relationship between symptom-based OSA and outcomes were explored using SPSS version 18.0 and stratified by obesity (BMI strata <30 and ≥30). Our primary outcome was the compound occurrence of SGA (fetal) or preeclampsia (maternal). Multivariate models were applied in controlling for potential confounders. RESULTS: The overall prevalence of OSA was 32.2 % and it was significantly related with the higher maternal BMI, more body weight at delivery, and weight gain during pregnancy (p = 0.007, p = 0.003, p = 0.005, respectively). There were no significant differences in the primary outcomes according to the positivity of OSA by screening, regardless of the stratification by obesity. The cesarean delivery rate was significantly higher in the OSA positive group (36.0 vs 22.5 %, p = 0.018), but it was not significant in the each strata of obesity. In multivariate analysis, the outcomes of birth weight, preeclampsia, cesarean delivery, and small for gestational age were also not different according to the positivity of OSA. CONCLUSIONS: It seems that the prevalence of OSA by a sleep questionnaire is overestimating OSA in Korean pregnant women. Polysomnography might be needed to diagnose OSA and to evaluate the relationship between OSA and the occurrence of SGA or preeclampsia.

Association of maternal thyroid disease with obesity in child.

OBJECTIVES: During pregnancy, many women develop thyroid disorders, which can result in fetal and neonatal development defects. We investigated whether maternal thyroid dysfunction would affect their children's growth and obesity. STUDY DESIGN: We conducted a nationwide population-based cohort study using a combination of data from several Korean nationwide registries to investigate the association between maternal thyroid dysfunction, offspring growth, and obesity. Childhood growth was repeatedly measured at three periods of age from 42 to 80 months, using body mass index (BMI). RESULTS: A total of 1,123,499 women were enrolled in this study; 78,902 (7.0 %) had pre-pregnancy thyroid disease. Significant association was found between maternal hyperthyroidism and obesity in all children aged 42-66 months (42-54 months, adjusted odds ratio (aOR) 0.93, 95 % confidence interval (CI) 0.89-0.98; 54-66 months, aOR 0.93, 95 % CI 0.87-0.99), but not at later ages. In the analysis by sex, maternal hyperthyroidism was associated with childhood obesity in boys, whereas it was not associated with those in girls of any age. No association was observed between maternal hypothyroidism and child BMI or obesity. CONCLUSIONS: The association between maternal thyroid function and obesity in offspring is attenuated from early to late childhood, suggesting that many other factors may be involved in developing childhood obesity.

A large amniocele with protruded umbilical cord diagnosed by 3D ultrasound.

An amniocele is a herniation of the amniotic sac through a uterine defect. Uterine rupture during pregnancy may develop as a result of a pre-existing injury, uterine anomaly, or unscarred uterus. A 30-year-old patient, with a history of 2 vaginal deliveries, presented an amniocele complicated by left fundal perforation and was evaluated with 3-dimensional ultrasound at 23 weeks. Because of worsening lower abdominal pain and vaginal bleeding, she underwent exploratory laparotomy. Herein, we report a uterine rupture with amniocele.

Clinical efficacy of cervical length and volume for prediction of labor onset in VBAC candidates.

BACKGROUND: The purpose of this research is to discover whether measurement of cervical length and cervical volume at term is helpful in predicting the onset of labor in VBAC candidates. METHODS: Transvaginal sonographic evaluations of the cervixes of pregnant women who desired to undergo VBAC were performed between 36 - 40 weeks gestation. Clinical information such as labor onset time, gestational age at delivery and delivery mode was gathered from medical records. RESULTS: A total of 514 pregnant women participated in this study. Cervical length was significantly longer in the group that delivered 7 days or more after measurement than in the group that delivered within 7 days of measurement (43±0.77 cm vs. 2.99±0.72 cm, p< 0.001). Cervical volume was significantly larger in the group that delivered at and after 7 days than in the group that delivered within 7 days (29.21±11.62 cm(3) vs. 34.07±13.41 cm(3), p=0.014). The cervical length ROC curve was significantly more predictive than the cervical volume ROC curve (AUC: 0.711 vs 0.594, p= 0.001). There were no significant differences between the combined cervical length/volume ROC curve and the cervical length ROC curve alone (p= 0.565). The AUC of the cervical length ROC curve to predict postterm pregnancy was 0.729. CONCLUSION: Measuring cervical length is helpful in predicting the onset of spontaneous labor within 7 days and posterm delivery in VBAC candidates.

Adverse Pregnancy Outcomes and Maternal Chronic Diseases in the Future: A Cross-Sectional Study Using KoGES-HEXA Data.

Adverse pregnancy outcomes (APOs) are associated with an increased risk of chronic diseases, including cardiovascular disease (CVD) and metabolic syndrome (MS), in the future. We designed a large-scale cohort study to evaluate the influence of APOs (preeclampsia, gestational diabetes mellitus (GDM), stillbirth, macrosomia, and low birth weight) on the incidence of chronic diseases, body measurements, and serum biochemistry in the future and investigate whether combinations of APOs had additive effects on chronic diseases. We used health examinee data from the Korean Genome and Epidemiology Study (KoGES-HEXA) and extracted data of parous women (n = 30,174; mean age, 53.02 years) for the analysis. Women with APOs were more frequently diagnosed with chronic diseases and had a family history of chronic diseases compared with women without APOs. Composite APOs were associated with an increased risk of hypertension, diabetes mellitus, hyperlipidemia, angina pectoris, stroke, and MS (adjusted odds ratio: 1.093, 1.379, 1.269, 1.351, 1.414, and 1.104, respectively) after adjustment for family history and social behaviors. Preeclampsia and GDM were associated with an increased risk of some chronic diseases; however, the combination of preeclampsia and GDM did not have an additive effect on the risk. APOs moderately influenced the future development of maternal CVD and metabolic derangements, independent of family history and social behaviors.

Maternal Gestational Diabetes Influences DNA Methylation in the Serotonin System in the Human Placenta.

The offspring of mothers with gestational diabetes mellitus (GDM) are at a higher risk for metabolic dysregulation and neurodevelopmental impairment. Evidence suggests that serotonin, which is present in both the placenta and the brain, programs the development and growth of the fetal brain. In the current study, we tested the hypothesis that GDM affects the methylation of the serotonin transporter gene (SLC6A4) and serotonin receptor gene (HTR2A) in the placenta. Ninety pregnant women were included in this study. Thirty mothers were diagnosed with GDM, and sixty mothers served as controls in a 1:2 ratio. Ten CpG sites within the promoter regions of SLC6A4 and HTR2A were analyzed using pyrosequencing. The relative expression of genes involved in DNA methylation was evaluated using real-time PCR. The average DNA methylation of placental SLC6A4 was higher in the GDM group than in the control group (2.29 vs. 1.16%, p < 0.001). However, the average DNA methylation level of HTR2A did not differ between the two groups. SLC6A4 methylation showed a positive correlation with maternal plasma glucose level and neonatal birth weight percentile and a negative correlation with the neonatal head circumference percentile. This finding suggests that epigenetic modification of the placental serotonin system may affect placental adaptation to a harmful maternal environment, thereby influencing the long-term outcome in the offspring.

Clinical significance of soft markers in second trimester ultrasonography for pregnant Korean women: a multicenter study and literature review.

OBJECTIVE: To evaluate the clinical significance of soft markers for aneuploidy screening in Korean women. METHODS: We retrospectively reviewed the medical records of 5,428 singleton pregnant women who underwent sonography during the second trimester at seven institutions in South Korea. We evaluated the prevalence of the following soft markers: intracardiac echogenic focus, choroid plexus cysts, pyelectasis, echogenic bowel, and mild ventriculomegaly. We developed best-fitted regression equations for the fetal femur and humerus length using our data and defined a short femur and humerus as both long bones below the fifth centile. The results of genetic testing and postnatal outcomes were investigated in patients who had been diagnosed with aforementioned soft markers. RESULTS: The median maternal age of our study population was 33 years, and the median gestational age at the time of ultrasonographic examination was 21 weeks. We detected soft markers in 10.0% (n=540) of fetuses: 9.3% (n=504) were isolated cases and 0.7% (n=36) of cases had two or more markers. We identified only two aneuploides (trisomy 18, 46,XX,t[8;10][q22.1;p13]), of which one was clinically significant. We presented the neonatal outcomes of the fetuses with the respective soft markers. Preterm delivery, low birth weight, and small-for-gestational-age (SGA) were significantly more common in women with a shortened fetal femur (P<0.001, all). However, the presence of a shortened fetal humerus was not associated with those outcomes excluding SGA. CONCLUSION: Soft markers in second-trimester ultrasonography have limited use in screening for fetal aneuploidy in Korean women. However, these markers can be used as a screening tool for adverse outcomes other than chromosomal abnormality.

Comparison of cervical parameters by three-dimensional ultrasound according to parity and previous delivery mode.

BACKGROUND: We would like to find out that whether the patient's parity, previous delivery mode and previous labor could influence cervical parameters. Cervical length, volume and width were measured using two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasound on normal pregnant women. METHOD: This study was conducted between January 2009 and December 2010 in singleton pregnant women who were admitted for routine antenatal care at hospitals in affiliation with the Catholic University, Seoul, Korea. The study group was classified by parity (nullipara and multipara) and previous delivery mode (cesarean section group and vaginal delivery group). The previous cesarean section group was divided by elective group who did not undergo labor and labor group who underwent labor. Cervical parameters such as cervical length, volume and width were measured using 2D and 3D ultrasound examinations in the first and second trimesters and the results were analyzed between those groups mentioned above. RESULTS: One hundred and twenty-one pregnant women in their 1st trimester and 233 pregnant women in their 2nd trimester (a total of 354) were enrolled in this study. Cervical parameters were not statistically significant from parity, nor previous delivery mode and previous labor in 1st trimester. Cervical volumes were not statistically significant from nullipara and elective cesarean section groups (35.96±9.81 vs. 34.73±9.75 cm3), but the nullipara groups were significantly lowered in the vaginal group (35.96±9.81 vs. 43.10±11.87 cm3) in 2nd trimester. For the nullipara group, cervical widths were not statistically significant in the elective cesarean section group but these were significantly lower than labor and previous vaginal group in the 2nd trimester. CONCLUSION: The cervical volume and width have an influence on parity, previous delivery mode and labor in the 2nd trimester.

Umbilical arterial blood gas and perinatal outcome in the second twin according to the planned mode of delivery.

PURPOSE: To compare umbilical arterial gas parameters in the second twin of twin pregnancies according to the mode of delivery. METHODS: We retrospectively analyzed the medical records of twin deliveries after 34 weeks of gestation for 3 years. Excluding the cases which underwent emergency cesarean delivery during trial of labor, a total of 79 twin gestations had umbilical arterial blood gas values available and were and divided into cesarean delivery group (N=40) and vaginal delivery group (N=39). The mean differences of umbilical arterial blood parameters and the Apgar score between the first and second twin in each pregnancy were compared according the mode of delivery. RESULTS: The differences of umbilical arterial gas parameters between twin siblings showed no significant difference according to the mode of delivery. With regard to the 1 minute and 5 minute Apgar scores, the differences between twin siblings are significantly increased in vaginal delivery group compared to cesarean delivery group (p=0.048, and p=0.038, respectively). In comparing the 28 cases delivered vaginally with an inter-twin delivery interval < 10 minutes and 40 cases delivered by cesarean section, no significant differences were observed in the umbilical arterial gas parameters and Apgar scores. CONCLUSION: The inter-twin umbilical arterial blood gas parameters according to the mode of delivery showed no difference. For twin deliveries, it is relatively safe to plan for a vaginal delivery, but an effort should be made to reduce the inter-twin delivery interval time.

Rectal endometriosis with invasion into lymph nodes.

Although endometriosis is a common disease in women of reproductive age, rectal endometriosis is rare and lymph node involvement by endometriosis is considered uncommon. We report a 37-year-old woman who had irregular lower abdominal pain and changes in bowel habits. She was operated on with suspected rectal cancer, but the histological diagnosis was rectal endometriosis with lymph node involvement. In women who suffer from digestive complaints, endometriosis should be considered in differential diagnosis. Rectal endometriosis has the ability to invade adjacent tissue as true malignant tumors. Therefore, lymph node involvement should be considered in rectal endometriosis.

Cytokine-related genes and oxidation-related genes detected in preeclamptic placentas.

PURPOSE: To investigate cytokine- and oxidation-related genes for preeclampsia using DNA microarray analysis. METHODS: Placentas were collected from 13 normal pregnancies and 13 patients with preeclampsia. Gene expression was studied using DNA microarray. Among significantly expressed genes, we focused on genes associated with cytokines and oxidation, and the results were confirmed using quantitative real time-polymerase chain reaction (QRT-PCR). RESULTS: 415 genes out of 30,940 genes were altered by > or =2-fold in the microarray analysis. 121 up-regulated genes and 294 down-regulated genes were found to be in preeclamptic placenta. Six cytokine-related genes and 5 oxidation-related genes were found from among the 121 up-regulated genes. The cytokine-related genes studied included oncostatin M (OSM), fms-related tyrosine kinase (FLT1) and vascular endothelial growth factor A (VEGFA), and the oxidation-related genes studied included spermine oxidase (SMOX), l cytochrome P450, family 26, subfamily A, polypeptide 1 (CYP26A1), acetate dehydrogenase A (LDHA). These six genes were also significantly higher in placentas from patients with preeclampsia than in those from women with normal pregnancies. The placental tissue of patients with preeclampsia showed significantly higher mRNA expression of these six genes than the normal group, using QRT-PCR. CONCLUSION: DNA microarray analysis is one of the great methods for simultaneously detecting the functionally associated genes of preeclampsia. The cytokine-related genes such as OSM, FLT1 and VEGFA, and the oxidation-related genes such as LDHA, CYP26A1 and SMOX might prove to be the starting point in the elucidation of the pathogenesis of preeclampsia.

Association between fetoplacental Doppler results, placental pathology, and angiogenic factors among pregnant women with anxiety.

OBJECTIVE: This study aimed to evaluate whether state and trait anxiety among pregnant women were associated with fetoplacental Doppler findings, abnormal placental pathology, and placental angiogenic factors. MATERIALS AND METHODS: A total of 102 pregnant women at 32-35 gestational weeks were recruited and examined prospectively. State and trait anxiety were measured using the State-Trait Anxiety Inventory. Using Doppler ultrasound, pulsatility index (PI) of the umbilical artery (UA), middle cerebral artery (MCA), and uterine artery (UtA) and cerebroplacental ratio (CPR) were determined. Doppler parameters were converted into multiples of the median (MoM). Abnormal placental pathology was classified into 2 groups: vascular underperfusion (VU) and histological chorioamnionitis (HCA). Immunohistochemical analysis was performed to examine placental cells staining positive for placental growth factor (PLGF) and hypoxia-inducible factor-1-α (HIF-1α), which are markers for angiogenesis and hypoxic status, respectively. RESULTS: Women with high state anxiety scores had low MCA-PI MoM and CPR MoM, while those with high trait anxiety scores had low MCA-PI MoM. VU was associated with a higher incidence of high trait anxiety scores, and HCA was associated with a higher incidence of high state and trait anxiety scores. Regression analysis showed a relationship between maternal state anxiety on MCA-PI MoM and HCA after controlling for covariates. Maternal trait anxiety exhibited relationships with VU and HCA after adjustment. CONCLUSION: Our results demonstrated that maternal anxiety is associated with altered fetal cerebral blood flow and abnormal placental pathology but is not associated with uteroplacental insufficiency and placental angiogenic factors.
