The Effect of Prophylactic Phenylephrine and Ephedrine Infusions on Umbilical Artery Blood pH in Women With Preeclampsia Undergoing Cesarean Delivery With Spinal Anesthesia: A Randomized, Double-Blind Trial.

Spinal anesthesia for cesarean delivery is associated with a high incidence of hypotension. Phenylephrine results in higher umbilical artery pH than ephedrine when used to prevent or treat hypotension in healthy women. We hypothesized that phenylephrine compared to ephedrine would result in higher umbilical artery pH in women with preeclampsia undergoing cesarean delivery with spinal anesthesia.


Recurrent Coronary Artery Spasm Induced by Vasopressors During Two Operations in the Same Patient Under General Anesthesia.

Variant angina is caused by coronary artery spasm (CAS) with ST-segment elevation. We herein report a case of recurrent CAS during 2 operations in the same patient. An 80-year-old woman was scheduled to undergo tracheostomy, submandibular dissection, left partial maxillectomy, and coronoidectomy. We administered ephedrine and phenylephrine to manage hypotension during general anesthesia. Immediately after the administration of these drugs, the ST segment elevated. We decided to cease the operation and trans...

Interleukin 11 is upregulated in preeclampsia and leads to inflammation and preeclampsia features in mice.

Preeclampsia is a dangerous pregnancy complication, which is often associated with fetal growth restriction and can have serious life-long effects for both mother and baby. While the establishment of the placenta in the first trimester is the sentinel event in the development of preeclampsia little is known of the critical mechanisms of placentation that lead to the syndrome. Locally produced inflammatory cytokines are thought to play a role in the development of preeclampsia. This review summarizes the evi...


Phenylephrine does not improve oxygenation during one-lung ventilation: A randomized, double-blind, cross-over study.

Phenylephrine is an α1 adrenergic receptor agonist that causes pulmonary vasoconstriction, and so may effectively enhance hypoxic pulmonary vasoconstriction (HPV). However, there is little evidence that phenylephrine augments HPV in clinical situations. This study aimed to evaluate the clinical effects of phenylephrine infusion on oxygenation during one-lung ventilation (OLV) in patients undergoing thoracic surgery.

LncRNA CCAT1 promotes the progression of preeclampsia by regulating CDK4.

Preeclampsia is one of the leading causes of maternal and perinatal deaths. This study mainly explored the mechanism of long non-coding RNA (lncRNA) CCAT1 expression in the placenta of preeclampsia patients and its effect on the progression of preeclampsia.

A tag SNP in syncytin-2 3-UTR significantly correlates with the risk of severe preeclampsia.

Preeclampsia is a disease that frequently complicates pregnancy and poses a serious threat to maternal and fetal health. The causes and pathogenic mechanisms of preeclampsia are poorly defined. Genetic predisposition could be an important etiological factor. Previous studies have demonstrated that syncytin-1 and syncytin-2, encoded by the genes ERVWE1 and ERVFRDE-1, are involved in the pathogenesis of preeclampsia.

Aspirin for Evidence-Based Preeclampsia Prevention trial: effect of aspirin on length of stay in the neonatal intensive care unit.

Preeclampsia is a major pregnancy complication with adverse short- and long-term implications for both the mother and baby. Screening for preeclampsia at 11-13 weeks' gestation by a combination of maternal demographic characteristics and medical history with measurements of biomarkers can identify about 75% of women that develop preterm-preeclampsia with delivery at

Maternal allergy as an isolated risk factor for early-onset preeclampsia: An epidemiological study.

Immunological mechanisms underlying the development of preeclampsia are well known, but no association to allergy has yet been demonstrated. The aim of this study was to assess the correlation between maternal pre-gestational allergy, and early-onset and late-onset preeclampsia, respectively. It was a retrospective cohort study including all women giving birth in the Norwegian cities of Stavanger (1996-2014) and Bergen (2009-2014). Pre-gestational asthma, allergy, other known risk factors for preeclampsia, ...

Blood-based cerebral biomarkers in preeclampsia: Plasma concentrations of NfL, tau, S100B and NSE during pregnancy in women who later develop preeclampsia - A nested case control study.

To evaluate if concentrations of the neuronal proteins neurofilament light chain and tau are changed in women developing preeclampsia and to evaluate the ability of a combination of neurofilament light chain, tau, S100B and neuron specific enolase in identifying neurologic impairment before diagnosis of preeclampsia.

Phosphodiesterases and preeclampsia.

Antagonizing vasodilation has been considered one of the potential mechanisms underlying the pathophysiology of preeclampsia. Phosphodiesterases hydrolyze cGMP, interfering with the action of nitric oxide on vascular smooth muscle, thus causing vasoconstriction. We hypothesize that the phosphodiesterases in maternal plasma, phosphodiesterase-5 in particular, may be linked to clinical manifestations in preeclampsia syndrome.

Early pregnancy immune biomarkers in peripheral blood may predict preeclampsia.

We performed a prospective cohort study in 197 pregnant women. Peripheral blood was collected between 5 and 16 weeks of gestation. Intracellular cytokine analysis and immunophenotype were performed by flow-cytometry. Serum levels of cytokines and chemokines were analyzed by multiplex assay. 86 patients were eligible for the analysis and 10.5% (n=9) developed preeclampsia. Patients with preeclampsia had significantly higher percentage of CD3(+)CD4(+)TNFα(+) T helper (Th) 1 cells (45.4±10.3 vs 37.1±8.5, P=...

Omega-3 Long-Chain Polyunsaturated Fatty Acids and Preeclampsia: Trials Say "No," but Is It the Final Word?

Preeclampsia is a dangerous disorder of pregnancy, defined as hypertension with proteinuria. Its nature remains elusive, and measures of prevention and treatment are limited. Observational studies have suggested that preeclampsia is associated with low intake of omega-3 long-chain polyunsaturated fatty acids (LCPUFA). In recent decades, researchers studied LCPUFA supplementation as a measure to prevent preeclampsia. Most of these trials and later systematic reviews yielded negative results. However, these t...

Novel SNPs of WNK1 and AKR1C3 are associated with preeclampsia.

Preeclampsia is a hypertensive disorder of pregnancy and is one of the most common causes of poor perinatal outcomes. Preeclampsia increases the risk of hypertension in the future. Variants of WNK1 (lysine deficient protein kinase 1), ADRB2 (β2 adrenergic receptor), NEDD4L (ubiquitin-protein ligase NEDD4-like), KLK1 (kallikrein 1) contribute to hypertension, and AKR1C3 (aldo-keto reductase family1 member C3), is associated with preeclampsia. The association of single nucleotide polymorphisms (SNPs) in thes...

Similar pro-NT and pro-RLX2 levels after preeclampsia and after uncomplicated pregnancy.

Women are at increased risk of developing cardiovascular disease (CVD) after preeclampsia. Proneurotensin 1-117 (pro-NT) and prorelaxin 2 connecting peptide (pro-RLX2) have recently emerged as potential biomarkers for CVD risk in women. We assessed pro-NT and pro-RLX2 levels in women with and without a history of preeclampsia.

The trophoblast survival capacity in preeclampsia.

Preeclampsia has become the world's major maternal health problem putting a huge burden on mothers, newborns and also on the health systems. The pathogenesis of preeclampsia seems to include events in very early pregnancy affecting differentiation of placental villous trophoblast. The arising changes of the cell death spectrum from apoptosis via increased autophagy and aponecrosis to necrosis in turn induce systemic inflammation of the mother.

Proteomics Analysis Reveals Abnormal Electron Transport and Excessive Oxidative Stress Cause Mitochondrial Dysfunction in Placental Tissues of Early-Onset Preeclampsia.

Early-onset preeclampsia (EOS-PE) refers to preeclampsia that occurred before 34 gestation weeks. This study was conducted to explore the relationship between mitochondrial dysfunction and the pathogenesis of EOS-PE using proteomic strategy.

Comparison of double intravenous vasopressor automated system using nexfin versus manual vasopressor bolus administration for maintenance of haemodynamic stability during spinal anaesthesia for caesarean delivery: A randomised double-blind controlled trial.

Hypotension is a common side effect of spinal anaesthesia during caesarean delivery and is associated with maternal and foetal adverse effects. We developed an updated double intravenous vasopressor automated (DIVA) system that administers phenylephrine or ephedrine based on continuous noninvasive haemodynamic monitoring using the Nexfin device.

DAI-1 Receptor Expression in Placenta in Earlyand Late-Onset Preeclampsia.

DAI-1 receptor (DNA-dependent activator of IFN-regulatory factors; DLM-1/ZBP-1) is an innate immunity cytoplasmic receptor of the DNA-recognition receptor class of antiviral immunity. DAI-1 expression reflects the severity of the inflammatory response that plays the key role in the pathogenesis of pregnancy complications. We studied DAI-1 receptor expression in the placental villi in early- and late-onset preeclampsia. In case of early-onset preeclampsia DAI-1 staining intensity was lower (p=0.01), and in c...

Celastrol attenuates symptoms of preeclampsia in rats by inhibiting matrix metalloproteinase-9.

Preeclampsia is reported in pregnant women around the world and often causes maternal/fetal mortality and morbidity. In the current study, we assessed the efficacy of celastrol on a rat preeclampsia model induced by N-nitro-L-arginine methyl ester hydrochloride (L-NAME). Pregnant rats were administered L-NAME to establish preeclampsia. A total of 48 animals were randomly assigned into 4 groups (n=12 each): control, control plus celastrol treatment (control+celastrol), preeclampsia, and preeclampsia plus cel...

Residential agricultural pesticide exposures and risks of preeclampsia.

We investigated risks of preeclampsia phenotypes from potential residential pesticide exposures, including 543 individual chemicals and 69 physicochemical groupings that were applied in the San Joaquin Valley of California during the study period, 1998-2011. The study population was derived from birth certificate data linked with Office of Statewide Health Planning and Development maternal and infant hospital discharge data. The following numbers of women with preeclampsia phenotypes were identified: 1045 w...

Angiogenic factors sFlt-1 and PlGF in preeclampsia: prediction of risk and prognosis in a high-risk obstetric population.

Despite its simple definition, preeclampsia can have variable and atypical clinical presentations, an unpredictable course, and potential adverse maternal and fetal outcomes. No single test currently predicts risk or prognosis adequately. Scientific advances suggest that an angiogenic imbalance is involved in its pathophysiology. The objective of this study was to investigate the use of sFlt-1, PlGF, and their ratio in predicting preeclampsia. Materials and methods In a single-center prospective observation...

Inflammatory Markers and Preeclampsia: A Systematic Review.

Preeclampsia (PE), a serious and variable pregnancy complication affecting 5%-10% of the obstetric population, has an undetermined etiology, yet inflammation is concomitant with its development, particularly in relation to endothelial dysfunction.

Lipid profile and cytokines in hypertension of pregnancy: A comparison of preeclampsia therapies.

Hypertensive disorders complicating pregnancy can be classified as gestational hypertension, mild preeclampsia, and severe preeclampsia. It is necessary to evaluate and predict the grade in advance. The first study comprised 40 healthy pregnancies, 40 gestational hypertension, 40 mild preeclampsia, and 40 severe preeclampsia cases. The participants' lipid profile and cytokine levels were statistically compared. The efficacy and safety of oral nifedipine (n = 71) and intravenous labetalol (n = 72) for th...
