Analysis of risk factors for postpartum depression after cesarean section in women with early-onset preeclampsia

BACKGROUND Early-onset preeclampsia significantly increases maternal and fetal morbidity and mortality.Many pregnant women with early onset preeclampsia choose cesarean section as their delivery method.Although extensive research has explored the association between postpartum depression(PPD)and cesarean section,few studies have investigated the risk factors after cesarean section in women with early-onset preeclampsia.AIM To examine these risk factors through a retrospective,observational analysis of 287 women who underwent a cesarean section for early preeclampsia between June 2014 and March 2024.METHODS Participants were assessed in person during the 32nd week of pregnancy,2 days post-cesarean,and 6 weeks postpartum.According to the Edinburgh Postnatal Depression Scale(EPDS),participants who underwent cesarean section were divided into PPD(n=60)and non-PPD groups(n=227).Furthermore,PPD was diagnosed at 6 weeks postpartum according to depressive symptoms(EPDS score≥11).The demographic and clinical features of PPD were screened.Multivariate logistic regression analysis was used to identify PPD risk factors.RESULTS The prevalence of PPD was 20.9%(60/287)among the 287 women who underwent cesarean section for early-onset preeclampsia.Multivariate logistic regression analyses revealed that advanced age(age>40 years)[odds ratio(OR)=1.93,95%CI:1.31-2.82],previous preeclampsia(OR=7.15,95%CI:5.81-8.85),pre-pregnancy obesity(OR=2.42,95%CI:1.62-3.63),gestational diabetes mellitus(OR=3.52,95%CI:2.51-4.92),preexisting hypertension(OR=1.35,95%CI:1.03-1.89),PPD symptoms(EPDS≥11)at 2 days postpartum(OR=6.15,95%CI:1.32-28.35),high prenatal self-rating anxiety scale score(OR=1.13,95%CI:1.06-1.18),and pain at 6 weeks postpartum(OR=2.16,95%CI:1.28-3.66)were independently associated with PPD.CONCLUSION Risk factors for PPD after cesarean section in women with early-onset preeclampsia include advanced age(age>40 years),pre-pregnancy obesity,previous preeclampsia,gestational diabetes mellitus,preexisting hypertension,PPD symptoms(EPDS≥11)at 2 days postpartum,prenatal anxiety,and pain at 6 weeks postpartum.The early identi-fication of these factors and interventions can mitigate the risk of PPD.

Effect of Lipoxin A_4 on IL-1β Production of Monocytes and Its Possible Mechanism in Severe Preeclampsia

This study examined in vitro effect of lipoxin A 4 (LXA 4) on interleukin-1β (IL-1β) production of monocytes and its possible mechanism in severe preeclampsia (PE).Peripheral venous blood was drawn from 15 patients with severe preeclampsia (PE group) and 20 normal pregnant women (control group) to prepare monocytes which were then treated with LXA 4 at different concentrations of 0,10,100 nmol/L respectively.IL-1β level in the supernatant of monocytes was detected by enzyme linked immunoassay.The [Ca 2+ ] i of monocytes was measured by laser scanning confocal microscopy.The results showed that the IL-1β level and the [Ca 2+ ] i of monocytes in the PE group were significantly higher than those in the control group.LXA 4 significantly decreased the generation of IL-1β in a dose-dependent manner in the PE group.After treatment with 100-nmol/L LXA 4,in the PE group,the [Ca 2+ ] i concentration of monocytes was significantly reduced.It was concluded that LXA 4 may inhibit the IL-1β production of monocytes from severe preeclampsia women by inhibiting extracellular calcium influx.

Maternal and Perinatal Complications of Severe Preeclampsia in Three Referral Hospitals in Yaoundé, Cameroon

Objective: The aim of this study was to determine maternal and perinatal complications of pregnancies complicated by severe preeclampsia in three tertiary care centers in Cameroon. Methods: We carried out a descriptive cross sectional study from the 1st of June 2012 to the 31th of June 2014, among pregnant women with severe preeclampsia followed up in three tertiary level hospitals in Yaoundé, Cameroon: the Yaoundé General Hospital, the Yaoundé Central Hospital, and the Yaoundé University Hospital. Statistical analysis was performed using EPI 3.5.5. Data were described as means ± standard deviation, percentages and numbers. Chi-square and Fisher exact tests were used where appropriate. Results: Of the 2500 deliveries registered during the study period, 111 cases (8.49%) were managed as severe preeclampsia. Four patients refused to participate and were excluded from the study. Most of these patients were non workers (58.0%), pauciparous (61.7%) and young (median age of 27.47 years ± 6.46). Eclampsia (12.14%), abruptio placentae (11.21%) and hypertensive retinopathy (7.47%) were the most frequent maternal complications. Two cases (1.86%) of maternal deaths occurred in patients who had eclampsia. Prematurity (48.6%), intra uterine fetal death (13.1%) and oligoamnios (11.2%) were the most frequent fetal complications. All four neonatal deaths occurred in women in whom the diagnosis of severe preeclampsia was done between 28 and 33 weeks of gestation. Conclusion: Pregnancies complicated by severe preeclampsia had significantly high maternal and perinatal morbidity and mortality in Cameroon. The complications of severe preeclampsia can be prevented by more widespread use of antenatal care, education of primary medical care personnel, prompt diagnosis of high-risk patients and timely referral to tertiary medical centers.

Impact of Adding Midazolam to Bupivacaine 0.5% in Regional Spinal Anesthesia on Maternal Middle Cerebral Artery Velocimetry in Parturients with Severe Preeclampsia

Severe preeclampsia is a challenging issue facing both intensivist and anesthetic team carrying both maternal and fetal morbidity and mortality. Termination of pregnancy after blood pressure control is the golden key in management. Cerebral complications due to diffuse cerebral vasospasm are most common and serious. Intrathecal midazolam with its gamma amino butyric action may antidote glutamate mediated sympathetic surge and decreasing cerebral vasospasm. Temporal view transcranial Doppler imaging maternal middle cerebral artery is used to examine blood flow indices namely pulsatility index and resistive index. One hundred ladies with severe preeclampsia scheduled for urgent caesarian section were recruited in 2 groups, both received 10 mg bupivacaine 0.5%, Midazolam group received 1 mg midazolam and the other group received 0.2 ml sterile saline 0.9% NaCl. All vascular indices were significantly better in midazolam group, less ICU stay.

Erratum to “Anesthetic Dilemma: Spinal Anesthesia in a Severe Pre-Eclamptic Patient with Twin Gestation, Heart Failure and Acute Pulmonary Edema”

Background: Severe preeclampsia with acute pulmonary oedema possesses great challenges to the anaesthetist. If not well managed, it could be associated with high maternal morbidity and mortality rate as well as fetal wastage. Aim: To sensitize the anaesthetist that when confronted with such a dilemma, well managed low spinal block can be a useful and successful anaesthetic technique. Methods: We report the case of a 23-year-old primigravida with twins gestation at 36 weeks, who presented with severe ante-partum pre-eclapsia, acute pulmonary oedema and acute heart failure. Blood investigations done were normal, and clotting time was within normal range. Her clinical conditions were optimized through a well thoughtful medication after which a low dose spinal anesthesia was performed using 1.5 mls (7.5 mg) of 0.5% hyperbaric bupivacaine (Modified saddle). The baby was delivered through a low segment caesarean section. Conclusion: The procedure was well tolerated and successful. Low spinal is associated with low incidence of hypotension and do not require pre-loading.

Rationale of a Cross-Sectional Descriptive Study on Associated Factors and Prognosis Maternal-Fetal Links to Early Onset Preeclampsia at the University Clinics of Kinshasa, DR Congo

Background: Preeclampsia (PE) is one of the forms of hypertensive diseases that occur during pregnancy. Early-onset preeclampsia (EOP), which occurred before 34 weeks, proved to be the deadliest. Indeed, it is characterized by a poor maternal and fetal prognosis. EOP has a disparate incidence in the world varying between 0.9% and 31%. Several risks factors are associated with the occurrence of EOP, which is responsible of several adverse obstetrical outcomes. Complications can affect up to 85% of pregnant women with EOP, especially when EOP appears very early, before 28 or even 25 weeks’ gestation. Objectives: To determine frequency of EOP at the University Clinics of Kinshasa, to describe sociodemographic and clinical characteristics of pregnant women with EOP and to identify its risks factors and its association adverse obstetrical outcomes. Methods: The study will be a cross-sectional analytical study in University Clinics of Kinshasa from January 2016 to December 2022. The minimal size will be 119. Our study population will consist of pregnant women who consult for antenatal best care and are neonates in our Clinic. Result will be presented as percentage proportion. Comparison and proportion means between groups will be made using Student’s test and Pearson’s chi-square test, respectively. Our test will be statistically significant for a p-value ≤ than less 0.05. Data will be collected and analysed anonymously and confidentiality. Conclusion: We believe that our study should enable us to identify profile of gestational carriers at risk of EOP in our environment, as well as prognosis associated with this entity, with a view to arousing particular interest in EOP.

目的:探究孕妇外周血微小RNA-152(miR-152)、miR-210与子痫前期(PE)病情程度及妊娠结局的相关性。方法:选取2018年7月至2022年5月我院200例PE患者,根据病情严重程度分为轻度组(轻度PE患者,n=114)和重度组(重度PE患者,n=86),另选同期、同年龄段健康孕妇作为对照组(n=100)。比较三组血压[收缩压(SBP)、舒张压(DBP)]、24h尿蛋白定量(24h Upro)、钙离子(Ca^(+))、外周血miR-152、miR-210水平,分析外周血miR-152、miR-210水平与PE病情程度、血压、24h Upro及Ca^(+)相关性。PE患者随访至妊娠结束,比较不同妊娠结局PE患者临床资料、外周血miR-152、miR-210水平,通过Lasso回归和Logistic回归分析预测因素与不良妊娠结局的关联性,通过受试者工作特征曲线(ROC)、临床决策曲线(DCA)评价外周血miR-152、miR-210对预测PE患者发生不良妊娠结局的价值及临床效用。结果:重度组、轻度组、对照组SBP、DBP、24h Upro、外周血miR-152、miR-210水平比较,差异有统计学意义(P<0.05);外周血miR-152、miR-210水平与PE病情程度、血压、24h Upro呈正相关(P<0.05),与Ca^(+)水平呈负相关(P<0.05);发生不良妊娠结局年龄、流产史、病情程度、SBP、DBP、24h Upro、Ca^(+)、外周血miR-152、miR-210水平与未发生不良妊娠结局患者比较,差异有统计学意义(P<0.05);Lasso回归选出5个预测变量为病情程度、SBP、24h Upro、外周血miR-152、miR-210水平;Logistic回归显示,外周血miR-152、miR-210水平是PE患者发生不良妊娠结局的独立危险因素(P<0.05);ROC、DCA结果显示,外周血miR-152、miR-210联合预测PE患者发生不良妊娠结局具有良好的预测价值和临床效用。结论:外周血miR-152、miR-210在PE患者中表达上调,且与病情程度、妊娠结局显著相关,其联合预测患者发生不良妊娠结局具有一定参考价值和临床效用。

重度子痫前期并发心功能不全的危险因素分析

目的探究重度子痫前期(severe preeclampsia,sPE)出现心功能不全相关的危险因素。方法选取2020年1月至2023年9月于温州市中心医院住院的sPE并发心功能不全的患者32例作为实验组,并随机选取同时期心功能正常的sPE患者75例作为对照组。比较两组患者的一般资料和实验室指标的差异,采用二元Logistic回归分析探讨sPE出现心功能不全的危险因素。结果实验组患者出现呼吸衰竭、血管内溶血-肝酶升高-低血小板、感染的例数高于对照组,差异有统计学意义(P<0.05)。对照组发生新生儿窒息、新生儿转重症监护的例数高于实验组,差异有统计学意义(P<0.05)。两组患者的孕前体质量指数、孕期体质量增幅、血钙、白蛋白、血红蛋白、双胎、感染差异有统计学意义(P<0.05),二元Logistic回顾分析结果显示,孕前体质量指数增加、孕期体质量增幅≥20kg、低血钙、低白蛋白、中度贫血、孕期血压增加是sPE出现心功能不全的危险因素。结论孕期应积极控制血压、补钙、补铁、补充白蛋白、控制体质量;对sPE患者增加血钙、白蛋白、血红蛋白、血压相关指标监测的频率,积极控制血压、解痉、预防感染可减少sPE患者心功能不全的发生。
