Abstract
Introduction Fetal heart rate variability (fHRV) is a tool used to investigate the functioning of the fetal autonomic nervous system. Despite the significance of preeclampsia, fHRV during the latent phase of labor has not been extensively studied. This study aimed to evaluate fetal cardiac autonomic activity by using linear and nonlinear indices of fHRV analysis in women diagnosed with preeclampsia without hypertensive treatment during gestation, compared to normotensive women during the latent phase of labor. Methods A cross-sectional and exploratory study was conducted among pregnant women in the latent phase of labor, forming three study groups: normotensive or control (C, 38.8 ± 1.3 weeks of pregnancy, n = 22), preeclampsia with moderate features (P, 37.6 ± 1.4 weeks of pregnancy n = 10), and preeclampsia with severe features (SP, 36.9 ± 1.2 weeks of pregnancy, n = 12). None of the participants received anti-hypertensive treatment during their pregnancy. Linear and nonlinear features of beat-to-beat fHRV, including temporal, frequency, symbolic dynamics, and entropy measures, were analyzed to compare normotensive and preeclamptic groups. Results Significantly lower values of multiscale entropy (MSE) and short-term complexity index (Ci) were observed in the preeclamptic groups compared to the C group (p < 0.05). Additionally, higher values of SDNN (standard deviation of R-R intervals) and higher values of low-frequency power (LF) were found in the P group compared to the C group. Conclusion Our findings indicate that changes in the complexity of fetal heart rate fluctuations may indicate possible disruptions in the autonomic nervous system of fetuses in groups affected by undiagnosed preeclampsia during pregnancy. Reduced complexity and shifts in fetal autonomic cardiac activity could be associated with preeclampsia's pathophysiological mechanisms during the latent phase of labor.

J Obstet Gynaecol Res 2021; 47:1322-1329. [PMID: 33496028 DOI: 10.1111/jog.14675] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 12/24/2020] [Accepted: 01/11/2021] [Indexed: 11/29/2022]
Abstract
AIM To evaluate whether there is a statistically significant difference between the cord blood gas parameters of pregnancies complicated with preeclampsia and uncomplicated pregnancies and to show whether the amount of proteinuria affects fetal cord blood gas parameters in pregnancies complicated with preeclampsia. METHODS The study was designed retrospectively. Between 2016 and 2019, the neonatal results and cord blood gas results of 109 pregnant women who were diagnosed with preeclampsia and 75 nonpreeclamptic randomly selected pregnant women were compared. The preeclampsia group was divided into groups according to amount of proteinuria. SPSS 21.0 statistics program was used, and comparative analysis was carried out. RESULTS The data of the 109 preeclampsia cases and 75 control groups included in the study were compared, and there was no statistical difference between the fetal cord blood gas parameters between the groups (p > 0.05). The median first and fifth minute Apgar scores were found significantly lower in the preeclampsia group compared to the control group (6, 8 and 8, 9, respectively; p < 0.001). Also, the amount of proteinuria does not alter cord blood gas parameters (p > 0.05). CONCLUSION Preeclampsia poses a risk for the neonatal period as it reduces the neonatal Apgar scores due to the chronic hypoxic process it creates. However, it was observed that the amount of proteinuria, which is one of the diagnostic criteria, did not affect neonatal results on Apgar scores or fetal cord blood gas parameters.

Abstract
OBJECTIVE Comparing the value of umbilical cord arterial blood gas (UC-ABG) analysis in the prediction of neonatal mortality and morbidity in the preeclamptic versus healthy pregnancies with preterm birth. METHODS Eight hundred sixteen preterm (born at <37 gestational weeks) neonates with no other morbidities who were born by cesarean section were evaluated. Immediately after delivery, UC-ABG analysis was performed and the neonates were followed. RESULTS Preeclamptic women had lower umbilical cord blood (UCB) pH (7.2 4 ± 0.1 versus 7.2 7 ± 0.08, p = 0.008) and higher UCB base deficit (BD) (3.5 ± 3.7 versus 2.2 ± 3.4, p = 0.005) compared with controls. In the preeclamptic group, UCB metabolic acidosis (pH < 7.15 and B.D > 8) was not independently associated with neonatal morbidity or mortality, while in the control group UCB metabolic acidosis was independently associated with low 10-min Apgar (OR, 4.9; 95%CI 1.37-18.03), respiratory distress syndrome (OR, 2.37; 95%CI 1.05-6.17), intraventricular hemorrhage (OR, 3.01; 95%CI 1.13-7.99), and neonatal mortality (OR, 17.33; 95%CI 4.51-66.53). CONCLUSIONS The preterm neonates born to preeclamptic mothers have lower UCB pH and higher BD. In these neonates, UCB acidosis is not independently associated with any adverse neonatal outcomes. In contrast, in the preterm neonates born to healthy mothers, UCB metabolic acidosis is independently associated with neonatal mortality and morbidity.

Abstract
Pre-eclampsia and eclampsia have been known to us for centuries. Significant improvements have been made in our knowledge of the disease, however, delivery remains the only effective form of treatment. There is widespread variation of practice in the management of hypertensive disease in pregnancy, which may lead to substandard care. The use of aspirin in preventing pre-eclampsia, the lack of correlation between urinary protein and adverse outcome, and the ineffectiveness of corticosteroids in the management of hemolysis and elevated liver enzymes and low platelets syndrome are a few of the developments that will alter the way this condition is managed. This article aims to provide a general overview of pre-eclampsia, eclampsia and hemolysis, hemolysis and elevated liver enzymes and low platelets syndrome supported by the latest evidence, which will help the care provider adopt a focused approach and use the latest knowledge to understand and manage this old condition.

Abstract
Objective. To compare protein/creatinine ratio (PCR) in random urine sample levels and adverse outcomes in hypertensive pregnant women. Methods. A total of 370 medical charts from hypertensive pregnant women were reviewed and stratified into three groups according to different PCR in random urine sample levels (group 1: PCR < 0.3 mg/mg; group 2: PCR 0.3-1.99 mg/mg; group 3: PCR ≥ 2.0 mg/mg) and compared with composite maternal and perinatal outcomes. Those outcomes were severe hypertension, thrombocytopenia, high lactate dehydrogenase count, disseminated intravascular coagulation, abruptio placentae, HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome, eclampsia, perinatal death, newborn cerebral hemorrhage, respiratory distress syndrome of newborn, neonatal sepsis, and newborn small for gestational age. Results. To obtain a composite maternal adverse outcome the odds ratio [ORs] between PCR groups were 1.8 (95% confidence interval [CI]: 1.1-3.2) between groups 1 and 2, and 3.1 (95% CI: 1.5-6.3) between groups 1 and 3; for composite perinatal adverse outcomes, the ORs were 3.0 (95% CI: 1.5-5.9) between groups 1 and 2, and 3.4 (95% CI: 1.6-7.5) between groups 1 and 3. Conclusions. Hypertensive pregnant women with a PCR ≥ 0.3 mg/mg, had worse maternal and perinatal outcomes than those with PCR < 0.3 mg/mg. Above the cut-off of 0.3 mg/mg, higher PCRs are not associated with a significant increase in maternal and perinatal morbidity.

Abstract
Objective. The purpose of this study was to elucidate the impact of the clinical presentation on perinatal outcome in placental abruption.
Study Design. A retrospective study was performed in 97 placental abruptions. Placental abruptions were classified according to clinical presentation: pregnancy-induced hypertension (HT, n = 22), threatened premature labor and/or premature rupture of membranes (TPL/ROM, n = 35), clinically low risk (LR, n = 27), and others (n = 13). Perinatal outcomes were compared among the HT, TPL/ROM, and LR groups.
Results. The HT had significantly higher incidence of IUGR, IFUD, and low fibrinogen. The TPL/ROM had less severe disease. However, the LR had significantly higher incidence of IUFD, low UA pH < 7.1, low Apgar score of <7 at 5 min, and low fibrinogen. Conclusion. Disease severity in placental abruption is likely to depend on the clinical presentation.

Abstract
BACKGROUND Proteinuria is one of the essential criteria for the clinical diagnosis of pre-eclampsia. Increasing levels of proteinuria is considered to be associated with adverse maternal and fetal outcomes. We aim to determine the accuracy with which the amount of proteinuria predicts maternal and fetal complications in women with pre-eclampsia by systematic quantitative review of test accuracy studies. METHODS We conducted electronic searches in MEDLINE (1951 to 2007), EMBASE (1980 to 2007), the Cochrane Library (2007) and the MEDION database to identify relevant articles and hand-search of selected specialist journals and reference lists of articles. There were no language restrictions for any of these searches. Two reviewers independently selected those articles in which the accuracy of proteinuria estimate was evaluated to predict maternal and fetal complications of pre-eclampsia. Data were extracted on study characteristics, quality and accuracy to construct 2 x 2 tables with maternal and fetal complications as reference standards. RESULTS Sixteen primary articles with a total of 6749 women met the selection criteria with levels of proteinuria estimated by urine dipstick, 24-hour urine proteinuria or urine protein:creatinine ratio as a predictor of complications of pre-eclampsia. All 10 studies predicting maternal outcomes showed that proteinuria is a poor predictor of maternal complications in women with pre-eclampsia. Seventeen studies used laboratory analysis and eight studies bedside analysis to assess the accuracy of proteinuria in predicting fetal and neonatal complications. Summary likelihood ratios of positive and negative tests for the threshold level of 5 g/24 h were 2.0 (95% CI 1.5, 2.7) and 0.53 (95% CI 0.27, 1) for stillbirths, 1.5 (95% CI 0.94, 2.4) and 0.73 (95% CI 0.39, 1.4) for neonatal deaths and 1.5 (95% 1, 2) and 0.78 (95% 0.64, 0.95) for Neonatal Intensive Care Unit admission. CONCLUSION Measure of proteinuria is a poor predictor of either maternal or fetal complications in women with pre-eclampsia.
