RESUMO

In this retrospective cohort study, we aimed to investigate the variables associated with progression to preeclampsia with severe features in parturients already diagnosed with mild hypertensive disorders of pregnancy. The study was conducted in a single university-affiliated medical center between 2018 and 2020. All women admitted due to hypertensive disorders were included. Data collected was compared between parturients who progressed and did not progress to preeclampsia with severe features. Among 359 women presenting without severe features, 18 (5%) developed severe features, delivered smaller babies at lower gestational age, and with higher rates of cesarean delivery (p < 0.001 for all). Chronic hypertension, maternal diabetes, any previous gestational hypertensive disorder, gestational diabetes, number of hospitalizations, earlier gestational age at initial presentation, and superimposed preeclampsia as the preliminary diagnosis were all associated with preeclampsia progression to severe features. Previous delivery within 2-5 years was a protective variable from preeclampsia progression. Following regression analysis and adjustment to confounders, only gestational age at initial presentation and superimposed preeclampsia remained significant variables associated with progression to severe features (aOR 0.74 (0.55-0.96) and 34.44 (1.07-1111.85), aOR (95% CI), respectively, p < 0.05 for both) with combined ROC-AUC prediction performance of 0.89, 95% CI 0.83-0.95, p < 0.001. In conclusion, according to our study results, early gestational age at presentation and superimposed preeclampsia as the preliminary diagnosis are the only independent factors that are associated with progression to severe features in women already diagnosed with mild hypertensive disorders during pregnancy.

RESUMO

OBJECTIVE: To identify risk factors, maternal and neonatal adverse outcomes related to unintended lower segment uterine extension during cesarean delivery (CD). METHODS: A retrospective cohort analysis in a single, university-affiliated medical center between 1 January 2018 and 31 December 2019. All singleton pregnancies delivered by CD were included. Univariate and multivariate analyses were performed to identify maternal and obstetrical predictors for uterine extension during CD. For secondary outcomes, we assessed the correlation between uterine extension and any adverse maternal or neonatal outcome. Risk factors were analyzed using ROC statistics to measure their prediction performance for a uterine extension. RESULTS: Overall, 1746 (19.3%) CDs were performed during the study period. Of them, 121 (6.9%) CDs were complicated by unintended uterine extension. There was no difference in maternal demographics and clinical data stratified by uterine extension at CD. Uterine extensions were significantly more common following induction of labor, intrapartum fever, premature rupture of membranes, a trial of labor after cesarean, advanced gestational age, emergent CD, and in particular CD during the second stage of labor (37.2% vs. 6.5%) and after failed vacuum extraction (6.6% vs. 1.1%), p < .05 for all. The incidence of postpartum hemorrhage and re-laparotomy did not differ between the groups. Most of the extensions were caudal-directed (40.4%), and were closed by a two-layer closure (92%). Mean extension size was 4.5 ± 1.7 cm. Using multivariable analysis, the only factor that remained significant was CD at the second stage of labor (adjusted odds ratio (aOR) 54.2, 95% CI 4.5-648.9, p = .002), with an area under the ROC curve 0.653 (95% CI 0.595-0.712, p < .001). Emergent CD, body mass index, birth weight, failed vacuum attempt, and trial of labor after cesarean were not significant. For secondary outcomes, an unintended uterine extension was associated with longer operation time, higher estimated blood loss, greater pre- to post-CD hemoglobin difference, increased blood products transfusion, puerperal fever, and longer hospital stay. No clinically significant neonatal adverse outcomes were observed. CONCLUSIONS: In our cohort, second-stage CD was the strongest predictor for an unintended uterine extension. Following uterine extension, women had increased infectious and blood-loss morbidity.

RESUMO

OBJECTIVE: To evaluate the association between congenital uterine anomalies (CUA) and adverse perinatal outcomes stratified by type of anomaly. METHODS: A retrospective cohort study of all women delivered in one university-affiliated medical center between 2010 and 2017 with CUA. Multiple pregnancies and pregnancies complicated by fetal anomalies were excluded. Maternal and short-term neonatal outcomes were evaluated and compared between women with unification defects (unicornuate, bicornuate, or uterus didelphys), and canalization defects represented by septate uterus. Univariate analysis was utilized followed by multivariate analysis to adjust for confounders. p < .05 was considered significant. RESULTS: Among 167 pregnancies with CUA, 92 (55.1%) had bicornuate uterus, 32 (19.1%) septate uterus, 26 (15.6%) didelphys uterus, and 17 (10.1%) unicornuate uterus. Maternal demographics and obstetric characteristics were similar between women with unification and canalization defects. The entire cohort had high rates of preterm delivery (PTD), malpresentation, and cesarean delivery (CD) (25.7%, 42.5%, and 63.5%, respectively). In comparison to unification defects, pregnancies in women with canalization defects (septate uterus), had increased risk for PTD <32 weeks (12.5% vs. 2.9%, p = .02), and placental abruption (12.5% vs. 3%, p = .02), however, a lower overall rate of CD (46.9% vs. 67.4%, p = .03). Following adjustment to confounders (age, BMI, nulliparity, chronic hypertension, and smoking) none of the results remained statistically significant. There were no differences in neonatal outcomes between the groups. CONCLUSIONS: Overall, women with CUA have a high prevalence of adverse pregnancy outcomes. However, outcome does not differ by type of anomaly.
