Molecular Pathways of Cellular Senescence and Placental Aging in Late Fetal Growth Restriction and Stillbirth.

Abnormally accelerated, premature placental senescence plays a crucial role in the genesis of pregnancy pathologies. Abnormal growth in the third trimester can present as small for gestational age fetuses or fetal growth restriction. One differs from the other by the presence of signs of placental insufficiency and the risk of stillbirth. The majority of stillbirths occur in normally grown fetuses and are classified as "unexplained", which often leads to conclusions that they were unpreventable. The main characteristic of aging is a gradual decline in the function of cells, tissues, and organs. These changes result in the accumulation of senescent cells in mitotic tissues. These cells begin the aging process that disrupts tissues' normal functions by affecting neighboring cells, degrading the extracellular matrix, and reducing tissues' regeneration capacity. Different degrees of abnormal placentation result in the severity of fetal growth restriction and its sequelae, including fetal death. This review aims to present the current knowledge and identify future research directions to understand better placental aging in late fetal growth restriction and unexplained stillbirth. We hypothesized that the final diagnosis of placental insufficiency can be made only using markers of placental senescence.

COVID-19 and pregnancy - where are we now? A review.

The new acute respiratory disease severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is highly contagious. It has caused many deaths, despite a relatively low general case fatality rate (CFR). The most common early manifestations of infection are fever, cough, fatigue and myalgia. The diagnosis is based on the exposure history, clinical manifestation, laboratory test results, chest computed tomography (CT) findings and a positive reverse transcription-polymerase chain reaction (RT-PCR) result for coronavirus disease 2019 (COVID-19). The effect of SARS-CoV-2 on pregnancy is not already clear. There is no evidence that pregnant women are more susceptible than the general population. In the third trimester, COVID-19 can cause premature rupture of membranes, premature labour and fetal distress. There are no data on complications of SARS-CoV-2 infection before the third trimester. COVID-19 infection is an indication for delivery if necessary to improve maternal oxygenation. Decision on delivery mode should be individualised. Vertical transmission of coronavirus from the pregnant woman to the fetus has not been proven. As the virus is absent in breast milk, the experts encourage breastfeeding for neonatal acquisition of protective antibodies.

Cesarean scar pregnancy - case resports and literature review.

The current increase in the percentage of cesarean sections is accompanied by a significant growth in the incidence of cesarean scar pregnancies (CSP) located in the lower uterine segment, while the advancements in diagnostic ultrasound techniques have led to an increased number of CSP diagnoses. A misdiagnosed cesarean scar pregnancy, or one that is diagnosed too late, is a threat to the pregnant patient's life, and predisposes her to such complications as hemorrhage or uterine rupture, which often necessitate hysterectomy and therefore result in irreversible fertility loss. In this paper 4 cases of ectopic pregnancies located within the cesarean scar in women hospitalized at the university clinical center, within a short span of merely three months in 2018, are presented. The purpose of this paper is to indicate to doctors and gynecology and obstetric societies that there is a very urgent need for drawing up guidelines for CSP management. To this effect, information about individual cases should be gathered and analyzed thoroughly, latest reports followed, and knowledge skills and experience shared in order to be able to work out a procedure that is both effective and as safe as possible.

The temporal link between prenatal steroid therapy and labor.

Prematurity has been one of the greatest challenges faced by perinatal medicine for many years. The recommended therapy for women with threatened preterm labor at 24 to 34 weeks' gestation is a single course of glucocorticoids. The greatest benefits have been proven when labor occurs at least 24 hours, but no later than 7 days after steroid administration. Applied treatment is not without influence on neonates' development. AIM: The aim of this study is to analyze the time between the administration of a course of glucocorticoids to patients with threatened preterm labor between 24 and 34 weeks of gestation and labor. MATERIALS AND METHODS: 459 deliveries by patients between 24 and 34 weeks' gestation who had received betamethasone (two 12 mg doses) or dexamethasone (four 6 mg doses) were analyzed. Their indications for glucocorticoid therapy were divided into four categories: the signs of threatened preterm labor, premature rupture of membranes, iatrogenic prematurity and cervical incompetence. The neonates (n=530) were divided into two main groups: group 1 of those born within the first 7 days (n1=127) and group 2 of those born more than 7 days (n2=403) after the glucocorticoids therapy. Statistical analysis was performed using the Statistica 13.3 software with calculations performed using the Mann- Whitney U and χ2 tests, assuming the level of statistical significance of <0.05 (p<0.05). RESULTS: The neonates born within the first 7 days after the glucocorticoid therapy accounted for 23.96% (127 children). The average time of delay between the course of glucocorticoids and labor was 33 days, with the longest interval being 116 days. The most common indications for glucocorticoids were iatrogenic causes in group 1 (35.40%) and the signs of threatened preterm labor (67.63%) in group 2. CONCLUSIONS: The percentage of births at the recommended time after steroidotherapy (not later than 7 days) was lower than expected. The prenatal steroid therapy qualification methods, should be reanalyzed, especially when signs of preterm labor are observed.

Pregnancy and childbirth during the coronavirus pandemic - current stage of knowledge.

SARS-CoV-2 (Severe Respiratory Syndrome Coronavirus-2), is a new strain of ß-coronavirus. At the time of the current pandemic, pregnant women fear of infection by this pathogen and related consequences both for themselves and for their children. Adaptive changes occurring in the body of a pregnant woman can increase her susceptibility to infections, especially when it concerns the cardiopulmonary system. Clinical data relating to infection by this pathogen, referred to as Coronavirus Disease 2019 (COVID-19) in pregnant women are still limited. Most of the cases in which these data are available apply to the third trimester of pregnancy. This article provides an overview of a current knowledge and recommendations regarding the management of SARS-CoV-2 infection during pregnancy and its impact on the pregnancy outcome.

The sFlt-1/PlGF ratio values within the <38, 38-85 and >85 brackets as compared to perinatal outcomes.

Background Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) are used as markers of preeclampsia. The aim of this paper was to assess the correlations between the sFlt-1/PlGF ratio values within the <38, 38-85 and >85 brackets and perinatal outcomes in pregnancies that require determination of these markers. Methods A total of 927 pregnant patients between 18 and 41 weeks' gestation suspected of or confirmed with any form of placental insufficiency (preeclampsia, intrauterine growth restriction [IUGR], gestational hypertension, HELLP syndrome, placental abruption) were included in the study. In each of the patients, the sFlt-1/PlGF ratio was calculated. Patients were divided into three groups according to the sFlt-1/PlGF ratio brackets of <38, 38-85 and >85. Results Significantly worse perinatal outcomes were found in the sFlt-1/PlGF >85 group, primarily with lower cord blood pH, neonatal birth weight and shorter duration of gestation. Statistically significant correlations between the values of these markers and the abovementioned perinatal effects were found. Conclusion An sFlt-1/PlGF ratio value of >85 suggests that either preeclampsia or one of the other placental insufficiency forms may occur, which is associated with lower cord blood pH, newborn weight and earlier delivery. Determining the disordered angiogenesis markers and calculating the sFlt-1/PlGF ratio in pregnancies complicated by placental insufficiency may lead to better diagnosis, therapeutic decisions and better perinatal outcomes.

Maternal endothelial damage as a disorder shared by early preeclampsia, late preeclampsia and intrauterine growth restriction.

INTRODUCTION: Preeclampsia (PE) and intrauterine growth restriction (IUGR) are separate disease entities that have frequently been reported as sharing the same pathogenesis. In both of them, angiogenesis disorders and generalized endothelial damage with an accompanying inflammation are the dominant symptoms. In this study, we attempted to prove that both these processes demonstrate the same profile in early PE, late PE and IUGR patients, while the only difference is in the degree of exacerbation of the lesions. PATIENTS, MATERIALS AND METHODS: In 167 patients divided into four groups, three of those with early PE, late PE and IUGR and one control group, fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), high sensitive c-reactive protein (hsCRP) and fibronectin were determined. The behavior of these parameters in each of the groups was studied, and correlations between them were sought for. RESULTS: Higher concentrations of sFlt-1, hsCRP and fibronectin and a lower concentration of PlGF were found in the study groups compared to the control group. Significant correlations were observed between the factors concerned. CONCLUSIONS: The higher values of disordered angiogenesis markers, endothelial damage markers and inflammatory markers both in the PE and the intrauterine growth restriction (IUGR) groups suggest the existence of shared disorders in the development of these pathologies. The correlations between disordered angiogenesis markers and endothelial damage markers argue in favor of a mutual relationship between these two processes in the development of pathologies evolving as secondary to placental ischemia. The results obtained confirm that the lesion profiles are the same in both PE and IUGR patients, which can be utilized in developing common diagnostic criteria.

[Outline of the history of caesarean section ­ from ancient times to the end of 17th Century].

Problems with the childbirth accompanied the human civilization since its beginning. From the ancient times, physicians and other people specializing in healing, tried to help women in this special moment of life. At the base of this exceptional meaning of childbirth for humans lies the fact, that if something is going wrong there are two victims - mother and the child. As a result, many times there had been very dramatic attempts of help in this the most difficult journey which in his life every man is undergoing. In this paper a comprehensive review of literature about the history of caesarean section from ancient times to the end of 17th century was done.

Soluble receptors for advanced glycation end products and receptor activator of NF-κB ligand serum levels as markers of premature labor.

BACKGROUND: This study aimed to determine the relationships between secretory and endogenous secretory receptors for advanced glycation end products (sRAGE, esRAGE), sRANKL, osteoprotegerin and the interval from diagnosis of threatened premature labor or premature rupture of the fetal membranes to delivery, and to evaluate the prognostic values of the assessed parameters for preterm birth. METHODS: Ninety women between 22 and 36 weeks' gestation were included and divided into two groups: group A comprised 41 women at 22 to 36 weeks' gestation who were suffering from threatened premature labor; and group B comprised 49 women at 22 to 36 weeks' gestation with preterm premature rupture of the membranes. Levels of sRAGE, esRAGE, sRANKL, and osteoprotegerin were measured. The Mann-Whitney test was used to assess differences in parameters between the groups. For statistical analysis of relationships, correlation coefficients were estimated using Spearman's test. Receiver operating characteristics were used to determine the cut-off point and predictive values. RESULTS: In group A, sRAGE and sRANKL levels were correlated with the latent time from symptoms until delivery (r = 0.422; r = -0.341, respectively). The sensitivities of sRANKL and sRAGE levels for predicting preterm delivery were 0.895 and 0.929 with a negative predictive value (NPV) of 0.857 and 0.929, respectively. In group B, sRAGE and sRANKL levels were correlated with the latent time from pPROM until delivery (r = 0.381; r = -0.439). The sensitivity of sRANKL and sRAGE for predicting delivery within 24 h after pPROM was 0.682 and 0.318, with NPVs of 0.741 and 0.625, respectively. Levels of esRAGE and sRANKL were lower in group A than in group B (median = 490.2 vs 541.1 pg/mL; median = 6425.0 vs 11362.5 pg/mL, respectively). CONCLUSIONS: Correlations between sRAGE, sRANKL, and pregnancy duration after the onset of symptoms suggest their role in preterm delivery. The high prognostic values of these biomarkers indicate their usefulness in diagnosis of pregnancies with threatened premature labor.

Pregnancy delivery and puerperium in a patient with lysinuric protein intolerance--a case report.

The paper presents the course of pregnancy delivery and early postpartum period in a 23-year-old woman with lysinuric protein intolerance (LPI). The pregnancy was uneventful and resulted in a caesarean birth to a healthy baby at 37 weeks gestation. Nevertheless, the course of pregnancy in women with LPI is associated with a significantly increased risk of serious complications, including acute hyperammonemia, preeclampsia and postpartum bleeding, as well as fetus intrauterine growth retardation. In many cases, intensive metabolic monitoring and a proper diet with protein limitation and appropriate amino acids supplementation may significantly reduce the risk for both the mother and the newborn.

Low-Dose Aspirin after ASPRE-More Questions Than Answers? Current International Approach after PE Screening in the First Trimester.

Preeclampsia (PE) is a multi-factorial disorder of pregnancy, and it continues to be one of the leading causes of fetal and maternal morbidity and mortality worldwide. Aspirin is universally recommended for high-risk women to reduce preeclampsia risk. The purpose of this review is to summarize the recommendations of various scientific societies on predicting preeclampsia and their indications for the inclusion of acetylsalicylic acid (ASA) prophylaxis. Fourteen guidelines were compared. The recommended dose, screening method, and gestational age at the start of the test vary depending on the recommendation. The societies are inclined to recommend using increasingly higher doses (>75 mg) of ASA, with many encouraging doses from 100 mg upward. Most societies indicate that the optimal time for implementing aspirin is prior to 16 weeks' gestation. Following the publication of the Aspirin for Evidence-Based Preeclampsia Prevention (ASPRE) trial results and other papers evaluating the Fetal Medicine Foundation (FMF) screening model, a large number of societies have changed their recommendations from those based on risk factors alone to the ones based on the risk assessment proposed by the FMF. This allows for the detection of a high-risk pregnancy population in whom aspirin will be remarkably effective in preventing preterm PE, thereby decreasing maternal and fetal morbidity.

Evidence of Placental Aging in Late SGA, Fetal Growth Restriction and Stillbirth-A Systematic Review.

During pregnancy, the placenta undergoes a natural aging process, which is considered normal. However, it has been hypothesized that an abnormally accelerated and premature aging of the placenta may contribute to placenta-related health issues. Placental senescence has been linked to several obstetric complications, including abnormal fetal growth, preeclampsia, preterm birth, and stillbirth, with stillbirth being the most challenging. A systematic search was conducted on Pubmed, Embase, and Scopus databases. Twenty-two full-text articles were identified for the final synthesis. Of these, 15 presented original research and 7 presented narrative reviews. There is a paucity of evidence in the literature on the role of placental aging in late small for gestational age (SGA), fetal growth restriction (FGR), and stillbirth. For future research, guidelines for both planning and reporting research must be implemented. The inclusion criteria should include clear differentiation between early and late SGA and FGR. As for stillbirths, only those with no other known cause of stillbirth should be included in the studies. This means excluding stillbirths due to congenital defects, infections, placental abruption, and maternal conditions affecting feto-maternal hemodynamics.

Preoperative Oral Carbohydrate (CHO) Supplementation Is Beneficial for Clinical and Biochemical Outcomes in Patients Undergoing Elective Cesarean Delivery under Spinal Anaesthesia-A Randomized Controlled Trial.

BACKGROUND: Preoperative fasting and surgery cause metabolic stress, insulin resistance with ketosis, and postoperative nausea and vomiting (PONV). Oral carbohydrate loading strategy (CHO) improves outcomes in labor and general surgery. We aimed to compare the effectiveness of CHO with standard fasting in patients undergoing elective cesarean delivery (CD) under spinal anesthesia. METHODS: A single-center, parallel, prospective randomized controlled trial (RCT) was conducted in a tertiary university obstetrics department at Pomeranian Medical University in Szczecin, Poland. Patients were randomly assigned (1:1 ratio) to the CHO group (oral carbohydrate 2 h before elective CD, n = 75) or the SF group (control-standard fasting, n = 73). The main outcome measures were incidence and severity of PONV at 6 and 24 h after CD, time to the first peristalsis, time to first bowel movement, and biochemical parameters indicating ketosis in mothers and their children. RESULTS: A total of 148 adult females with singleton pregnancies undergoing elective CD under spinal anesthesia (ASA I and II) were included in the final analysis. At 24 h after CD, 8.0% from the CHO group vs. 20.55% reported three or more episodes of vomiting or dry retching as compared to patients in the SF group (p = 0.041). Preoperative CHO supplementation decreased preoperative feelings of hunger (p < 0.001) and thirst (p < 0.001). Laboratory results in the CHO group showed higher plasma pH (p = 0.001) and glucose (p < 0.001), lower F2-isoprostane in plasma (p = 0.049) and urine (p = 0.018), lower urine F2-isoprostane/creatinine ratio (p = 0.045) than in the SF group. HOMA-IR (p < 0.001) and lactate (p < 0.001) were higher in the CHO group than in the control group. CONCLUSIONS: There was no significant difference in the incidence or severity of early PONV at 6 h. The incidence of vomiting or dry retching at 24 h after cesarean delivery was lower in the CHO group as compared to standard starvation, but the combined results of PONV frequency and severity on the Wengritzky scale did not differ between the two study groups. Preoperative CHO supplementation decreased preoperative feelings of hunger and thirst, enhancing the comfort of pregnant women. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04069806.

Screening for Preeclampsia and Fetal Growth Restriction in the First Trimester in Women without Chronic Hypertension.

BACKGROUND: Nowadays, it is possible to identify a group at increased risk of preeclampsia (PE) and fetal growth restriction (FGR) using the principles of the Fetal Medicine Foundation (FMF). It has been established for several years that acetylsalicylic acid (ASA) reduces the incidence of PE and FGR in high-risk populations. This study aimed to evaluate the implementation of ASA use after the first-trimester screening in a Polish population without chronic hypertension, as well as its impact on perinatal complications. MATERIAL AND METHODS: A total of 874 patients were enrolled in the study during the first-trimester ultrasound examination. The risk of PE and FGR was assessed according to the FMF guidelines, which include the maternal history, mean arterial pressure (MAP), uterine artery pulsatility index (UtPI), pregnancy-associated plasma protein A (PAPP-A) and placental growth factor (PLGF). Among patients with a risk higher than >1:100, ASA was administered at a dose of 150 mg. Perinatal outcomes were assessed among the different groups. RESULTS: When comparing women in the high-risk group with those in the low-risk group, a statistically significantly higher risk of pregnancy complications was observed in the high-risk group. These complications included pregnancy-induced hypertension (PIH) (OR 3.6 (1.9-7)), any PE (OR 7.8 (3-20)), late-onset PE (OR 8.5 (3.3-22.4)), FGR or small for gestational age (SGA) (OR 4.8 (2.5-9.2)), and gestational diabetes mellitus type 1 (GDM1) (OR 2.4 (1.4-4.2)). The pregnancies in the high-risk group were more likely to end with a cesarean section (OR 1.9 (1.2-3.1)), while the newborns had significantly lower weights (<10 pc (OR 2.9 (1.2-6.9)), <3 pc (OR 10.2 (2.5-41.7))). CONCLUSIONS: The first-trimester screening test for PE and FGR is a necessary and effective tool in identifying high-risk pregnancies. ASA prophylaxis among high-risk patients may have the most beneficial effect. Furthermore, this screening tool may significantly reduce the incidence of early-onset PE (eo-PE).

Emergency cerclage using double-level versus single-level suture in the management of cervical insufficiency (Cervical Occlusion double-level Stitch Application, COSA): study protocol for a multicentre, non-blinded, randomised controlled trial.

INTRODUCTION: Cervical insufficiency accounts for 15% of recurrent pregnancy losses between 16 and 28 weeks of gestation. The aim of the study is to verify the effectiveness of emergency double-level cerclage with vaginal progesterone in cervical insufficiency treatment in terms of the prevention of preterm delivery before 34 weeks of gestation. METHODS AND ANALYSIS: This trial is a multicentre, non-blinded, randomised study with 1:1 allocation ratio. The study is conducted at tertiary perinatal care departments in Poland. It will include patients with cervical insufficiency with the fetal membranes visible in the open cervical canal or protruding into the vagina between 16+0 and 23+6 weeks of pregnancy. They will be randomised into two arms: emergency single-level cerclage with vaginal progesterone or double-level cerclage with vaginal progesterone. All will be administered antibiotics and indomethacin. The primary outcome is the rate of deliveries below 34+0 weeks of gestation, while secondary outcomes include gestational age at delivery, neonatal outcomes, maternal outcomes according to the Core Outcome Set for Evaluation of Interventions to Prevent Preterm Birth and cerclage procedure complications. The planned number of participants according to the power analysis is 78. ETHICS AND DISSEMINATION: The study protocol was written in accordance with the Standard Protocol Items: Recommendations for Interventional Trials statement. It was created according to the requirements of the Declaration of Helsinki for Medical Research involving Human Subject. Ethical approval was obtained from the Ethics Committee of the Centre of Postgraduate Medical Education (no. 1/2022). The study protocol was approved and published by ClinicalTrials.gov (posted on 24 February 2022). All participants gave a written informed consent. After completion of the study its results will be published in a peer-reviewed English language journal. TRIAL REGISTRATION: NCT05268640.

Uterine rupture in the second trimester of pregnancy as an iatrogenic complication of laparoscopic myomectomy.

Uterine rupture is one of the most dangerous obstetric emergencies carrying a high risk for the mother and the fetus. Reports about uterine rupture in pregnancy following previous laparoscopic surgery have not been frequent; however, an increasing rate of the occurrence of this complication has been observed and reviewed in contemporary literature. We report a case of a spontaneous uterine rupture at 22 weeks of gestation in a 25-year old primigravida, who had had a laparoscopic removal of a small, peduncular, asymptomatic myoma located in the right uterine horn 20 months earlier. Ultrasound examination and subsequent urgent laparotomy confirmed a spontaneous uterine rupture with a nonviable fetus in the peritoneal cavity. Women planning to become pregnant should be qualified for laparoscopic myomectomy with special carefulness. Special attention must be paid to the potential solutions that limit the risk of postoperative uterine rupture, if the absolute necessity for the enucleation of myomas during the reproductive age occurs and a decision about laparoscopic intervention is made.

[The influence of patient-controlled epidural analgesia on labor progress and neonatal outcome]. / Wplyw analgezji zewnatrzoponowej sterowanej przez pacjentke na przebieg porodu oraz stan urodzeniowy noworodków.

AIM: The aim of the study was to check the influence of patient control epidural analgesia on labor progress and neonatal outcome. MATERIAL AND METHODS: 144 parturients were included into the clinical trial. In 73 cases patient control epidural analgesia was used and in 71 cases pethidine (meperidine) solution was given intravenously. Apgar score, umbilical artery pH, pain intensity the time of the first, second and third stage of labor the rate of episiotomy and uterine postpartum abrasions and the rate of caesarean sections and vaginal operative delivery were compared. RESULTS: The time of the second stage of labor was significantly longer in the study group (40.99 vs 26.49 min, p- < 0.005), the neonatal outcome was comparable in both groups. There were no differences in the time of the first and the second stage of labor in primiparas and multiparas analyzed separately. Visual Analogue Score was lower in the study group (Ch(2)-12,48, p-0.25), especially in the subgroups of primiparas and multiparas. CONCLUSIONS: Patient control epidural analgesia does not affect the time of the first and second stage of labor, oxytocin augmentation of labor may be the reason of that. This method is a more effective way of relieving labor pain. An increase of operative delivery is not observed after patient control epidural analgesia on condition that low doses and concentrations of analgesic drugs are used.

Effectiveness of Different Algorithms and Cut-off Value in Preeclampsia First Trimester Screening.

Results: For the cut-off point >1 : 150, 86 women at an increased risk of eo-PE using algorithm 1 were identified. Of these 86 patients, 83 (96%) were identified using algorithm 2, 62 (72%) using algorithm 3, and 60 (69%) using algorithm 4. In addition, it was demonstrated that between 21% and 29% of women at a low risk of eo-PE could be given acetylsalicylic acid if a screening test was used that did not account for PlGF. Conclusions: In order to provide the highest level of health care to pregnant women, it is extremely important that full screening for eo-PE should be ensured. The cheapest algorithm based only on MAP and UtPI resulted in our patients being unnecessarily exposed to complications.

Birth Weight < 3rd Percentile Prediction Using Additional Biochemical Markers-The Uric Acid Level and Angiogenesis Markers (sFlt-1, PlGF)-An Exploratory Study.

(1) Aim: Ultrasound is the gold standard for assessing fetal growth disorders. The relationship between high sFlt-1/PlGF scores and LBW (low birth weight) was described. In this study, we attempted to assess whether uric acid could be used as a secondary marker in estimating the pregnancy risk associated with LBW. (2) Material and methods: 665 pregnant women with a suspected or confirmed form of placental insufficiency were enrolled. In each of the patients, sFlt-1 and PlGF and uric acid levels were determined. Patients were divided into two groups according to birth weight below and above the third percentile for the given gestational age with the criteria of the neonatal definition of FGR (fetal growth restriction). (3) Results: A significant negative correlation between neonatal birth weight and the uric acid level across the entire study group was observed. We found a significant negative correlation between neonatal birth weight and the uric acid level with birth weights < 3rd percentile. (4) Conclusions: There is a significant link between the uric acid concentration and LBW in the group with placental insufficiency. Uric acid can improve the prediction of LBW. An algorithm for LBW prognosis that makes use of biophysical (ultrasound) and biochemical (uric acid level, angiogenesis markers) parameters yields better results than using these parameters separately from each other.

Adverse Neonatal Outcome of Pregnancies Complicated by Preeclampsia.

Despite many available treatments, infants born to preeclamptic mothers continue to pose a serious clinical problem. The present study focuses on the evaluation of infants born to preeclamptic mothers for the occurrence of early-onset complications and attempts to link the clinical status of such infants to the angiogenesis markers in maternal blood (sFlt-1, PlGF). The study included 77 newborns and their mothers diagnosed with preeclampsia. The infants were assessed for their perinatal outcomes, with an emphasis on adverse neonatal outcomes such us infections, RDS, PDA, NEC, IVH, ROP, or BPD during the hospitalization period. The cutoff point was established using the ROC curve for the occurrence of any adverse neonatal outcome and it was 204 for the sFlt-1/PlGF and 32 birth week with AOC 0.644 and 0.91, respectively. The newborns born to mothers with high ratios had longer hospitalization times and, generally, were more frequently diagnosed with any of the aforementioned adverse neonatal outcomes. Also, the neonates born prior to or at 32 wkGA with higher sFlt-1/PlGF ratios were statistically significantly more common to be diagnosed with any of the adverse neonatal outcomes compared to those with lower ratio born prior to or at 32 wkGA. The sFlt-1/PlGF ratio can be a useful tool in predicting short-term adverse neonatal outcomes. Infants born after a full 33 weeks gestation developed almost no severe neonatal complications. Appropriate screening and preventive healthcare for preeclampsia can contribute significantly to reducing the incidence of neonatal complications.
