ObjectiveTo study the association between pre-pregnancy body mass index (BMI) and adverse maternal and neonatal outcomes of singleton pregnancies after assisted reproductive technology (ART).MethodsThis hospital-based retrospective cohort study of women with live singleton births through ART in China from January 2015 to August 2020 included 3043 Chinese women. According to the latest BMI classification standard of Asian women, the women included in this study were classified as underweight (BMI <18.5 kg/m2), normal (BMI 18.5 to <23 kg/m2), overweight (BMI 23 to <27.5 kg/m2), and obese (BMI ≥27.5 kg/m2). We compared the risk of adverse outcomes of different pre-pregnancy BMI values of women with singleton pregnancies conceived through ART. We used Logistic regression analysis to estimate the associations between pre-pregnancy BMI and adverse perinatal and neonatal outcomes.ResultsOur findings showed that women who were overweight or obese before pregnancy through ART are more likely to have a cesarean section, gestational diabetes mellitus, gestational hypertension, and preeclampsia, regardless of whether confounding factors are adjusted. Moreover, pre-pregnancy obesity was more associated with a higher risk of these adverse outcomes than pre-pregnancy overweight. In addition, neonates from women who had obesity before pregnancy through ART were more likely to have macrosomia; adjusted odds ratios and 95% confidence intervals were 3.004 (1.693-5.330).ConclusionsOur research showed that women who had pre-pregnancy overweight or obesity with singleton pregnancies through ART were more likely to have a cesarean section, gestational diabetes mellitus, gestational hypertension, and preeclampsia. Moreover, neonates from women who had obesity before pregnancy were more likely to have macrosomia.

Abstract OBJECTIVE: The purpose of this study is to explore the factors affecting the pregnancy outcome of patients with pulmonary hypertension, and to design a digital model predicting the pregnancy outcome of patients and judge whether patients have the conditions to continue pregnancy. METHODS: The clinical data of patients with pregnancy complicated with pulmonary hypertension hospitalized in Guangdong Provincial People's Hospital from January 1, 2014 to December 31, 2020 were retrospectively analyzed. The severity of pulmonary hypertension, the structural and functional indexes measured by echocardiography were compared, and the effects on maternal and neonatal outcomes were analyzed. RESULTS: A total of 158 patients met the inclusion and exclusion criteria. The results showed that tricuspid regurgitation velocity (P<0.001), right ventricular diameter (P<0.05), right atrial diameter (P<0.05), pulmonary artery diameter (P<0.001) and cardiac function classification (P<0.001) were risk factors for maternal outcomes; Tricuspid regurgitation velocity (P<0.001) and structural changes of right heart were risk factors for neonatal outcomes. By multivariate logistic regression analysis, tricuspid regurgitation velocity (P<0.001), cardiac function (P<0.05) and superior inferior diameter of right atrium (P<0.05) were significant risk factors for maternal outcomes, while tricuspid regurgitation velocity (P<0.001) and superior inferior diameter of right atrium (P<0.05) were significant risk factors for neonatal outcomes. Using significant risk factors, a risk score system was established to predict the pregnancy outcome. CONCLUSION: in this study, we analyzed the clinical data of patients with pregnancy complicated with pulmonary hypertension in our hospital in recent years, and found that the changes of right heart structure (the acceleration of tricuspid regurgitation velocity, and the increase of right atrium, right ventricular diameter, right ventricular outflow tract anteroposterior diameter and main pulmonary artery diameter), are influencing factors of pregnancy outcomes in patients with pulmonary hypertension. In addition, we preliminarily designed a risk score through multi factor analysis, which is helpful to predict the possible outcome of puerperium and neonatal outcomes of patients, and to provide some reference for clinicians and patients to make decisions on whether to continue pregnancy in clinical practice.

Abstract Background: Although first-trimester subchorionic hematoma (SCH) always concerns expectant parents, its clinical significance remains controversial. This study aimed to examine the relationship between first-trimester SCH and its association with subsequent miscarriage and other perinatal outcomes.Methods: We conducted a retrospective cohort study including 43,660 women who underwent routine prenatal care since the first trimester and then were followed up for maternal and neonatal outcomes. SCH was detected in the first-trimester ultrasound examinations. Robust Poisson regression was used to estimate adjusted risk associations between SCH maternal and neonatal outcomes.Results: A total of 815 (1.87%) SCH were detected in the first-trimester ultrasound examination. The rate of miscarriage was statistically significantly higher in women with SCH than in those without [35.2% vs. 23.9%, P<0.01; adjusted relative risk (RR):1.44, 95% confidence interval (CI): 1.31-1.58]. Subgroup analysis of women with SCH showed a clear trend that the earlier SCH occurred, the higher the risk of miscarriage was [adjusted RR and 95% CI for onset at the gestational weeks of 8-9, 6- 7, and <6 vs. ≥10: 1.30 (0.69-2.46), 2.33 (1.28-4.23), and 4.18 (2.30-7.58), respectively; Ptrend<0.01]. In addition, women with SCH volume ≥1ml showed higher risk than those <1 ml [adjusted RR and 95% CI for 1-4.9 ml, and ≥5 ml vs. <1 ml: 1.36 (1.10-1.68) and 1.56 (1.18-2.07), respectively]. There was no statistically significant difference in the rates of other pregnancy outcomes between women with and without SCH.Conclusions: First-trimester SCH might significantly increase the risk of miscarriage, particularly the one that occurs early and the one with large size. Data from this study do not suggest adverse effects of SCH on other maternal and neonatal outcomes.

Abstract Background Compared with singleton pregnancy, twin gestation is featured by a greater increase in cardiac output. Therefore, norepinephrine might be more suitable than phenylephrine for maintaining blood pressure during cesarean section for twins, as phenylephrine causes reflex bradycardia and a resultant decrease in cardiac output. This study was to determine whether norepinephrine was superior to phenylephrine in maintaining maternal hemodynamics during cesarean section for twins. Methods Informed consent was obtained from all the patients before enrollment. In this double-blinded, randomized clinical trial, 100 parturients with twin gestation undergoing cesarean section with spinal anesthesia were randomized to receive prophylactic norepinephrine (3.2 μg/min) or phenylephrine infusion (40 μg/min). The primary outcome was the change of heart rate and blood pressure during the study period. The secondary outcomes were to compare maternal complications, neonatal outcomes, Apgar scores and umbilical blood acid-base status between the two vasopressors. Results There was no significant difference observed for the change of heart rate between two vasopressors. The mean standardized area under the curve of heart rate was 78 ± 12 with norepinephrine vs. 74 ± 11 beats/min with phenylephrine (mean difference 4.4, 95%CI − 0.1 to 9.0; P = .0567). The mean standardized area under the curve of systolic blood pressure (SBP) was significantly lower in parturients with norepinephrine, as the mean of differences in standardized AUC of SBP was 6 mmHg, with a 95% CI from 2 to 9 mmHg (P = .0013). However, requirements of physician interventions for correcting maternal hemodynamical abnormalities (temporary cessation of vasopressor infusion for reactive hypertension, rescuing vasopressor bolus for hypotension and atropine for heart rate less < 50 beats/min) and neonatal outcomes were also not significantly different between two vasopressors. Conclusion Infusion of norepinephrine was not associated with less overall decrease in heart rate during cesarean section for twins, compared with phenylephrine.

Objectives: Women with Down syndrome (DS) suffer from several health issues, however, their fecundity is not affected. Despite that, there are no studies in the literature to address pregnancy, delivery, or neonatal outcomes among women with DS. Design: We conducted a retrospective study using the Health Care Cost and Utilization Project-Nationwide Inpatient Sample Database over 11 years from 2004 to 2014. Methods: A delivery cohort was created using ICD-9 codes. ICD-9 code 758.0 was used to extract the cases of maternal DS. Pregnant women with DS (study group) were matched based on age and health insurance type to women without DS (control) at a ratio of 1:4. A multivariant logistic regression model was used to adjust for statistically significant variables (P-value < 0.5). Results: There were a total of 9,096,788 deliveries during the study period. Of those, 185 pregnant women were found to have DS. The matched control group was 740. Maternal pregnancy risks mostly did not differ between those with and without DS including pregnancy-induced PIH, gestational diabetes, preeclampsia, PPROM, chorioamnionitis, cesarean section, operative vaginal delivery, or blood transfusion (P >0.05, all). However, they were at extremely increased risk of delivering prematurely (aOR 3.86, 95% CI 1.25-11.93), and to have adverse neonatal outcomes such as small for gestational age (aOR 13.13, 95% CI 2.20-78.41), intrauterine fetal demise (aOR 20.97, 95% CI 1.86-237.02), and congenital anomalies (aOR 9.59, 95% CI 1.47-62.72). Conclusion: Women with DS should be counseled about their increased risk of premature delivery and adverse neonatal outcomes.
