Immune Responses of Healthy Pregnant Women following an Elective Cesarean Section: Effects of Anesthetic Procedures.

A weakened immune system and more inflammatory cytokines being released are possible effects of the surgical stress that a cesarean section induces. This kind of reaction, in addition to the altered reaction to catecholamines, has the potential to significantly affect the immune system of the mother and the patients' general postoperative course. This prospective study compared the plasma levels of catecholamines and cytokines in healthy pregnant patients having cesarean sections under spinal anesthesia versus general anesthesia. A total of 30 pregnant women undergoing elective cesarean sections were divided into two groups: 15 who received general anesthesia (GA) and 15 who received spinal anesthesia (SA). Blood samples were collected from all subjects before anesthesia induction (pre-OP), 6 h postoperatively (6 h post-OP), and 12 h (12 h post-OP), to measure levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-8, IL-4, IL-10, norepinephrine (NE), and epinephrine (EPI). When we compared the two groups, we discovered that only IL-6 and IL-4 had significantly higher levels pre-OP, whereas all studied cytokines exhibited an increase in the GA versus SA group at 6 and 12 h post-OP. In the case of catecholamines, we discovered that serum levels are positively related with pro-inflammatory or anti-inflammatory cytokines, depending on the time of day and type of anesthetic drugs. Compared to SA, GA has a more consistent effect on the inflammatory response and catecholamine levels. The findings of this study confirm that the type of anesthesia can alter postoperative immunomodulation to various degrees via changes in cytokine and catecholamine production. SA could be a preferable choice for cesarean section because it is an anesthetic method that reduces perioperative stress and allows for less opioid administration, impacting cytokine production with proper immunomodulation.

Longitudinal 8-Epi-Prostaglandin F2-Alpha and Angiogenic Profile Mediator Evaluation during Pregnancy in Women with Suspected or Confirmed Pre-eclampsia.

Background: In this exploratory study, we aimed to evaluate the dynamics of angiogenic [soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), soluble Endoglin (sEng), and sFlt-1/PlGF, PlGF/sFlt-1, and sEng/PlGF ratios] and oxidative stress [8-epi-prostaglandin F2 alpha (8-epi-PGF2α) and 8-epi-PGF2α/PlGF ratio] mediator levels in women with suspected or confirmed pre-eclampsia (PE) at least two times during pregnancy. We also wanted to identify the possible correlations between 8-epi-PGF2α and angiogenic mediator levels at the time of inclusion of pregnant women. Methods: We included 40 pregnant women with suspected or confirmed PE, with a mean age of 29 years (range between 18 and 41 years) and gestational age between 18 and 28 weeks at inclusion in this study. The Enzyme-Linked Immunosorbent Assay (ELISA) method to measure the levels of serum angiogenic and oxidative stress mediators was used. Results: The evaluation of baseline sFlt-1/PlGF ratios using a cut-off of 38 suggested that 25 pregnant women had a sFlt-1/PlGF ratio of >38 (sFlt-1/PlGF ratio of >38 group) and 15 had a sFlt-1/PlGF ratio of ≤38 (sFlt-1/PlGF ratio of ≤38 group). The increases in sFlt-1/PlGF ratio in the sFlt-1/PlGF ratio of >38 group were caused by both an increase in sFlt-1 (2.04-fold) and a decrease in PlGF levels (2.55-fold). The 8-epi-PGF2α median levels were higher in the sFlt-1/PlGF ratio of >38 group (1.62-fold). During follow-up after pregnancy, we observed that the mean values of sFlt-1 and sEng and the median values of 8-epi-PGF2α and sFlt-1/PlGF, sEng/PlGF, and 8-epi-PGF2α/PlGF ratios increased directly proportional to gestational age for each measurement time until delivery in both groups. For five women who had a sFlt-1/PlGF ratio ≤38 at inclusion, sFlt-1/PlGF ratio was observed to increase to >38 later in pregnancy. We observed that, in the sFlt-1/PlGF ratio >38 group, baseline 8-epi-PGF2α levels better correlated with angiogenic mediator levels. Conclusions: Our study shows that 33.33% of pregnant women evaluated for suspected or confirmed PE with a sFlt-1/PlGF ratio of ≤38 displayed a rise in sFlt-1/PlGF ratio in subsequent weeks. In addition, together with angiogenic mediators, 8-epi-PGF2 α can be utilized as an independent predictor factor to help clinicians identify or predict which pregnant women will develop PE.

Association between Serum 8-Iso-Prostaglandin F2α as an Oxidative Stress Marker and Immunological Markers in a Cohort of Preeclampsia Patients.

BACKGROUND: We aimed to analyze the presence and clinical use of serum 8-iso-prostaglandin F2-alpha (8-iso-PGF2α) as an oxidative stress marker and some inflammatory status biomarkers (tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), IL-10, high-sensitivity C-reactive protein (hs-CRP), and pentraxin-3 (PTX3)) for patients with preeclampsia (PE). METHODS: Sixty pregnant women, including thirty diagnosed with PE and thirty who were healthy (NP), were included in this study. For the assessment of serum levels of biomarkers, we used the Enzyme-Linked Immunosorbent Assay (ELISA) technique. RESULTS: Our preliminary study showed that the expression level of serum 8-iso-PGF2α in the PE group was higher than in the PE after delivery (PE-AD) group (742.00 vs. 324.00 pg/mL, p < 0.0001). Groups of preeclamptic patients (PE + PE-AD) expressed significantly elevated levels for all of the assessed inflammatory mediators as compared to NP. Significant strong positive correlations with 8-iso-PGF2α levels were found for systolic blood pressure (SBP), and TNF-α (Spearman's rho = 0.622, p-value = 0.020 and rho = 0.645, p-value = 0.002, respectively). Our study demonstrates that 8-iso-PGF2α and PTX3 have the greatest diagnostic value for pregnant women with PE. CONCLUSIONS: 8-iso-PGF2α and PTX3 can be used as independent predictor factors, along with already-known cytokines, that could represent a prophylactic way to help clinicians identify or predict which pregnant women will develop PE.

The Role of Uterine Artery Doppler in the Second and Third Trimesters for Prediction of Preeclampsia and Fetal Growth Restriction Developed as a Consequence of Placental-Mediated Diseases.

Placenta-mediated pregnancy disorders represent a disease that includes preeclampsia (PE) and the birth of small for gestational age (SGA) children, these conditions increase the risk of mortality and morbidity both maternal and fetal/neonatal, in the short and long-term. METHODS: The prospective study included 106 patients in whom ultrasound Doppler scans of uterine artery (UtA) were performed in the 2nd trimester between 20.0-23.6 weeks of gestation and the 3rd trimester between 28.0-32.6 weeks of gestation. RESULTS: In the second trimester, the average of the UtA-PI percentiles was statistically significant (p<0.05) in correlation with PE and SGA, as in the third trimester. Statistically significant (p<0.05) was also the correlation of UtA-PI >95 percentile with the development of PE and SGA. On the other hand, the present notch, in the two trimesters studied, analyzed as a single index, did not present a statistically significant association (p>0.05). CONCLUSIONS: The results of our study showed that UtA-PI Doppler is the best predictor of preeclampsia considering the association of intrauterine growth restriction, as most studies have found.

Intraplacental Villous Artery Doppler can Improve the Ability to Predict Placenta-Mediated Disease.

OBJECTIVE: Evaluation of Intraplacental Villous Artery Doppler (IPVA) as a predictive factor compared to umbilical artery (UA) Doppler in placenta-mediated disease (PMD). METHODS: This prospective study included a group of 106 pregnant women, of which 76 patients constituted the PMD group: preeclampsia (PE) and small for gestational age (SGA), and 30 pregnant women constituted the control group. IPVA and UA Doppler evaluation was performed in 2 pregnancy periods: 20.0-23.6 weeks, and 28.0-32.6 weeks of gestation. RESULTS: From the study of maternal characteristics and risk factors for the presented pathology, we found that no studied risk factor was statistically involved in the evolution toward PMD during pregnancy. In the control group, we noticed a decrease in IPVA PI and RI, along with an increase in gestational age, while in the PMD group, these indices increased. Both in the 2nd and the 3rd trimester, we had a significant statistical difference between the two groups (p<0.001). Regarding the degree of prediction of the changes that occurred at this level, we found a good statistical correlation. A higher degree of positive predictability is noted, for IPVA-PI, but also for UA-PI, but with better sensitivity (72.27%) for UA PI in the 2nd trimester. CONCLUSIONS: We can conclude that both Doppler measurements, IPVA and UA can be used to evaluate and detect pregnancy complications that belong to PMD, preeclampsia, and/or fetal growth restriction.

Effect of Filler Types on Cellulose-Acetate-Based Composite Used as Coatings for Biodegradable Magnesium Implants for Trauma.

Magnesium alloys are considered one of the most promising materials for biodegradable trauma implants because they promote bone healing and exhibit adequate mechanical strength during their biodegradation in relation to the bone healing process. Surface modification of biodegradable magnesium alloys is an important research field that is analyzed in many publications as the biodegradation due to the corrosion process and the interface with human tissue is improved. The aim of the current preliminary study is to develop a polymeric-based composite coating on biodegradable magnesium alloys by the solvent evaporation method to reduce the biodegradation rate much more than in the case of simple polymeric coatings by involving some bioactive filler in the form of particles consisting of hydroxyapatite and magnesium. Various techniques such as SEM coupled with EDS, FTIR, and RAMAN spectroscopy, and contact angle were used for the structural and morphological characterization of the coatings. In addition, thermogravimetric analysis (TGA) was used to study the effect of filler particles on polymer thermostability. In vitro cytotoxicity assays were performed on MG-63 cells (human osteosarcomas). The experimental analysis highlights the positive effect of magnesium and hydroxyapatite particles as filler for cellulose acetate when they are used alone from biocompatibility and surface analysis points of view, and it is not recommended to use both types of particles (hydroxyapatite and magnesium) as hybrid filling. In future studies focused on implantation testing, we will use only CA-based composite coatings with one filler on magnesium alloys because these composite coatings have shown better results from the in vitro testing point of view for future potential orthopedic biodegradable implants for trauma.

Prediction of Preterm Birth with Serial Measurements of Ultrasound Markers.

To compare the ability of cervical length (CL), anterior cervical angle (ACA), and cervical consistency index (CCI) to predict premature birth. METHODS: This prospective study involved 85 pregnant women who gave birth prematurely and a control group of 31 pregnant women who gave birth at term. The study was performed in the Obstetrics and Gynecology Clinic of the Municipal Clinical Hospital Filanthropia Craiova between January 1, 2019, and January 1, 2022. Cases were examined using transvaginal ultrasonography (TVU) in the second and third trimesters of pregnancy, and cervical length (CL), Anterior Cervical Angle (ACA), and Cervical Consistency Index (CCI) were measured. RESULTS: The mean value from the three measurements at all three parameters was statistically significant with preterm birth (p<0.05). Cervical length <25mm, was highly significant in the prediction of preterm labor with a sensitivity of 99%, specificity of 61%, positive predictive value (PPV) of 78%, negative predictive value (NPV) of 97 %, and a positive likelihood ratio (LR+) of 2.54 and negative likelihood ratio (LR-) of 0.02. CCI also remains, despite low specificity and PPV values, a potential predictive parameter in the prediction of preterm birth, with a sensitivity of 73%, NPV of 92% and a LR+of 1.32 and LR- of 0.6 also correlated with CL, CCI being more difficult to interpret as an independent predictive parameter. CONCLUSIONS: CL remains the standard parameter for predicting the preterm birth, but in combination with other parameters, the prediction rate can increase significantly.

Analysis of the relationship between placental histopathological aspects of preterm and term birth.

OBJECTIVES: This study aims to establish a correlation between placental histopathological and immunohistochemical (IHC) changes and preterm birth with fetal growth restriction (FGR, formerly called intrauterine growth restriction - IUGR). PATIENTS, MATERIALS, AND METHODS: This prospective study was performed on a group of 30 parturients, with singleton gestation, of which 15 patients gave birth at term, and the other 15 patients gave birth prematurely. After the statistical correlation of the clinical and demographic data with premature birth (PB) and term birth (TB), we performed histological and IHC research on the respective placentae. To observe normal and pathological microscopic placental structures, we used the Hematoxylin-Eosin (HE) and Periodic Acid Schiff-Hematoxylin (PAS-H) classical stainings, but also special immunostaining with anti-cluster of differentiation 34 (CD34) and anti-vascular endothelial growth factor (VEGF) antibodies. RESULTS: We found a statistically significant difference between the TB∕PB categories and the age of the patients, their antepartum weight, the weight of the newborns, and the placenta according to the sex of the newborn. Histological analysis revealed in the case of TB, small areas of perivillous amyloid deposition, with the significant extension of these areas both intravillous and perivillous in the case of PB. Massive intravillous calcifications, syncytial knots, and intravillous vascular thrombosis were also frequently present in PB. With PAS-H staining were highlighted the intra∕extravillous vascular basement membranes, but especially the massive fibrin deposits rich in glycosaminoglycans. By the IHC technique with the anti-CD34 antibody, we noticed the numerical vascular density, higher in the case of TB, but in the case of PB, there were large areas of placental infarction, with a lack of immunostaining in these areas. Through the anti-VEGF antibody, we observed the presence of signal proteins that determined and stimulated the formation of neoformation vessels in the areas affected by the lack of post-infarction placental vascularization. We observed a highly significant difference between placental vascular density between TB∕PB and newborn weight, sex, or placental weight. CONCLUSIONS: Any direct proportional link between the clinical maternal-fetal and histological elements yet studied must be considered. Thus, establishing an antepartum risk group can prevent a poor pregnancy outcome.

Maternal obesity and placental pathology in correlation with adverse pregnancy outcome.

Maternal obesity is associated with increased maternal and fetal morbidity and mortality, with an increased risk of gestational diabetes mellitus (GDM) and preeclampsia (PE). This prospective study histopathologically analyzes the placentas obtained from 34 pregnant obese women studied between October 2016 and May 2020. The 10 cases of term placentas from obese pregnancies with GDM and the 12 cases with PE were examined by the Hematoxylin-Eosin (HE), Masson's trichrome (MT) and Periodic Acid-Schiff-Hematoxylin (PAS-H) classical stainings, and by the immunohistochemical evaluation and compared to placentae from uncomplicated term obese pregnancies (12 cases). We did not meet placental histopathological (HP) abnormalities that we could classify as characteristic only for the state of obese pregnancy, but we did find placental changes associated with PE and GDM, in the context of obese pregnancy. In the case of association with PE, there were common lesions, manifested by intra- and perivillous fibrinoid deposition, calcification, and placental infarction area, to which were added numerous syncytial knots. In the case of obese pregnancy associated with GDM, we found, in addition to common placental lesions of obesity, intravillositary vascular edema and in the terminal villi appearing chorangiosis. This study revealed a number of HP changes that occur in maternal obesity, even in uncomplicated obese pregnancies. A characteristic of obese pregnancies associated with PE was the presence of numerous syncytial knots, and in obese pregnancies associated with GDM, the most common HP lesion was placental chorangiosis. Certainly, we cannot conclude that these HP lesions are specific to a particular pathology, but they belong primarily to the status of maternal obesity.

Fetal-maternal incompatibility in the Rh system. Rh isoimmunization associated with hereditary spherocytosis: case presentation and review of the literature.

Next to A and B antigens, agglutinogen D exhibits the highest immunogenicity. Following the transfusion of D-positive red blood cells (RBCs), almost 80% of D-negative recipients develop anti-D antibodies (Abs). Subsequently, anti-D immunization further promotes the synthesis of Abs towards other blood group antigens in or outside the Rh system. The D antigen is also involved in 95% of cases of hemolytic disease of the newborn. Transfusions, hemotherapy, grafts, and obstetric history (abortions, ectopic pregnancy, births) are all risk factors for Rh isoimmunization. In the case of ABO compatibility between mother and fetus, Rh-positive fetal RBCs that have reached the maternal bloodstream are not destroyed by group agglutinins, and Rh antigenic sites are not hidden by the maternal immune system. But a Rh-negative mother with a homozygous Rh-positive husband will certainly have a Rh-positive fetus. As it has an irreversible evolution, the Rh isoimmunization once installed cannot be influenced in the sense of decreasing the Ab titer, therefore, injectable globulin has no effect. A particular case was that of a newborn with Rh system incompatibility associated with hereditary spherocytosis The clinical balance at birth reflects the severe jaundice of the female newborn of 3140 g, gestational age 38∕39 weeks, extracted by lower-segment transverse Caesarean section, with a double loop nuchal cord, Apgar score 8. Because the jaundice was severe and atypical (face and upper chest), we considered the possibility of coexistence of hemolytic disease of the newborn by Rh blood group incompatibility associated with hereditary spherocytosis, as it turned out to be true and mentioned. Changes in genes encoding proteins in the structure of the RBC membrane have amplified hemolysis induced by maternal-fetal isoimmunization in the Rh system. Massive hemolysis accentuated by congenital spherocytosis, confirmed later, imposed blood transfusion and dynamic monitoring.

Ductus Venosus Agenesis and Portal System Anomalies-Association and Outcome.

To evaluate the prenatal diagnosis of agenesis of ductus venosus (ADV) and portal venous system (PVS) anomalies and describe the outcome of these cases, either isolated or associated. We evaluated the intrahepatic vascular system regarding the presence of normal umbilical drainage and PVS characteristics in the second and third trimester of pregnancy. The associated anomalies and umbilical venous drainage were noted. Follow-up was performed at six months follow-up. Ultrasonography was performed in 3517 cases. A total of 19 cases were prenatally diagnosed: 18 ADV cases, seven abnormal PVS cases, and six associations of the two anomalies. We noted an incidence of 5.1‱ and 1.9‱ for ADV and PVS anomalies, respectively. Out of the 18 ADV cases, 27.7% were isolated. Five cases (26.3%) presented genetic anomalies. PVS anomalies were found in 33.3% of the ADV cases. ADV was present in 85.7% of the PVS anomalies. DV and PVS abnormalities were found with a higher than reported frequency. Normal DV is involved in the normal development of the PVS. Additional fetal anomalies are the best predictor for the outcome of ADV cases. Evaluation of PVS represents a powerful predictor for ADV cases and addresses the long-term prognosis.

The Ability of Doppler Uterine Artery Ultrasound to Predict Premature Birth.

OBJECTIVE: Demonstration of the predictive capacity of Doppler Uterine Artery (UtA) on preterm birth (PB) by serial measurement at various ages of pregnancy. METHODS: The prospective study included a group of 116 pregnant women, of whom 85 gave birth prematurely and 31 pregnant women gave birth at term, constituting the control group. UtA Doppler measurement was performed by the abdominal approach. Quantitative wave evaluations were performed by the pulsatility index (PI), the systole/diastole ratio (S/D), as well as the qualitative analysis of the flow rate waveform (notch). UtA Doppler evaluation was performed in 3 pregnancy periods: 18.0-22.6 weeks, 28.0-31.6 weeks, and 32.0-35.6 weeks. RESULTS: Only at the third examination, at 32.0-35.5 weeks of gestation, was there a statistically significant difference between the S/D-UtA ratio and PI-UtA correlated with the risk of premature birth (p<0.05). Although there was an association between UtA Doppler and late preterm birth, the predictive ability was low. Also, UtA Doppler was not statistically significant for preterm birth before 32 weeks of gestation. CONCLUSIONS: Although we did not find a statistical association between second-trimester UtA Doppler and preterm birth, we do suggest a closer look at women with abnormal UtA Doppler in the second trimester. We believe that, according to the results obtained, UtA Doppler can predict especially iatrogenic premature birth depending on the prediction of the most severe complications, severe preeclampsia, and SGA.

Impact of COVID-19 on fertility and assisted reproductive technology (ART): a systematic review.

The appearance of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a major obstacle for the performing of current medical activities throughout the world. COVID-19 has affected humanity in many ways, thus causing a great medical, social, economic, and political instability. The aim of this study was to make an analysis of the scientific data obtained by so far to highlight the impact that COVID-19 has had on fertility and assisted reproductive technology (ART). Infection with SARS-CoV-2 alters the normal immune response by local and systemic damage to tissues and organs. After the virus enters the body, the first lesions are produced in the respiratory tract. Extrapulmonary lesions specific to COVID-19 include acute renal lesions/acute kidney damage, hepatocellular lesions, neurological diseases, myocardial dysfunction and arrhythmia, gastrointestinal diseases but also genital impairment. The possible impairment of the male reproductive system is because angiotensin-converting enzyme 2 (ACE2) receptors are in an increased number in the testes, seminiferous duct cells, spermatogonia, Leydig cells and Sertoli cells. Many published studies to date have pointed out that COVID-19 could also affect female fertility and disrupt the functions of the female reproductive system. The theory that this virus can also be transmitted sexually and can cause infertility or testicular damage is supported by the fact that the virus can be isolated in the semen of COVID-19 patients but only during the disease. Choosing the best method of treating infertility during the COVID-19 pandemic is multifactorial, but the risk of infection and compliance with specific ART hygiene protocols must always be considered. Currently, there is no scientific basis regarding the fact that the COVID-19 vaccination would influence fertility.

Clinical and morphopathological assay in vulvovaginal candidiasis.

Candida vulvovaginitis is characterized by the appearance of inflammatory changes in the vaginal and vulvar epithelium secondary to infection with Candida species. The purpose of this study was to analyze and compare the clinical, microbiological, and histopathological aspects of pregnant and non-pregnant patients, symptomatic or asymptomatic in the case of candida vaginitis and to correlate the microscopic aspects with the symptoms before applying the local treatment with Nystatin. The study presents a retrospective analysis of the management of vaginitis in 166 pregnant or non-pregnant patients during 2021-2022. We observed the structure of the Malpighian squamous epithelium without keratinization present on the vaginal mucosa and the structure of the subepithelial connective tissue, which shows increased numerical values of inflammatory and vascular cellularity in the case of candida vaginitis symptomatic compared to asymptomatic ones. We noticed also in the microscopic study that in cases of asymptomatic patients before treatment, the number of inflammatory cells and blood vessels situated immediately under the epithelium was significantly lower compared to their number in symptomatic patients before treatment. Analyzing the results obtained after the administration of the treatment proposed by us, we can say that local Nystatin treatment is beneficial and safe for pregnant and non-pregnant patients and is a good alternative for patients with recurrent vulvovaginal candidiasis.

Maternal Lipid Profile as a Risk Factor for Gestational Diabetes Mellitus in Obese Women.

As dyslipidemia is frequently associated with gestational diabetes mellitus, the aim of this study was to establish a correlation between the evolution of the maternal lipid profile evaluated in the first and third pregnancy trimester for a series of parameters: triglycerides, cholesterol, high-density lipoprotein cholesterol (HDL-C), blood sugar fasting (BSF), triglyceride-glucose index (TyG index), TG/HDL-C ratio, leptin and the risk of gestational diabetes mellitus occurrence. The results were statistically interpreted, establishing the mean value of the obtained results and the standard deviation. From the studied parameters, only HDL-C and Tyg were statistically significant different in the  first trimester for the two study groups, while in the third trimester statistically significant differences were observed also for triglycerides, blood sugar fasting and the TG/HDL-C ratio.

Maternal Lipid Profile as Predictor for Mother and Fetus Outcome-an Artificial Neural Network Approach.

PURPOSE: The study aims to predict mother and fetus outcome based on the mother's lipid profile in the second and third trimester of pregnancy. MATERIAL AND METHOD: Blood and urinary samples were taken from 135 mothers that were prospectively monitored during the hole pregnancy. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), together with other parameters, were used as predictors in a multilayer perceptron (MLP) artificial neural network (ANN). Small for gestational age (SGA) was used to assess the fetal outcome, while Gestational diabetes mellitus (GDM) and, Hypertensive disorders in pregnancy (HDP) to assess the mother's outcome. RESULTS: SGA prediction rate was 0.637±0.022 for the second trimester and 0.632±0.017 for the third trimester. GDM prediction rate was 0.897±0.006 for the second trimester and 0.632±0.017 for the third trimester. HDP prediction rate was 0.620±0.046 for the second trimester and 0.775±0.030 for the third trimester. When used with other parameters (hemoglobin, thrombocytes, uric acid, GOT, GPT, the presence of proteinuria, urea, and creatinine) the prediction rates raised, going over 90% for the GDM. CONCLUSIONS: Though individual lipid parameters do not statistically correlate with the output variables the use of ANN generated prediction rates raging from 60% to 90%. The lipid profile from the third trimesters seems to be a better prediction for both fetus and mother outcome.

Doppler Uterine Artery Ultrasound in the Second Trimester of Pregnancy to Predict Adverse Pregnancy Outcomes.

PURPOSE: To determine in uterine artery (UtA) the mean pulsatility index (PI), systolic/diastolic (S/D) ratio and the presence/absence of notch in the second trimester of pregnancy, with normal or abnormal pregnancy outcome. MATERIAL AND METHODS: We performed an analysis of 135 cases with high risk pregnancy in Obstetrics and Gynecology Department of The Municipal Hospital Filantropia, Craiova, between October 2016 and May 2020. The ultrasound evaluation in the second trimester was performed during the second trimester morphology scan, or after this, but up to 24 weeks of pregnancy. RESULTS: The study showed only in the case of early preeclampsia (PE) a statistical significance for mean PI-UtA percentiles in the second trimester. In the other studied categories of pregnancy outcome, even we did not have a statistical significance, we found a specificity of 75% and positive predictive value of 88.89% in late PE. The presence of notch in the second trimester was statistically significant (p value <0.05) in the case of premature birth (PB) and early PE. A positive predictive value of 77.50% we found only in case of late PE. CONCLUSIONS: Our results show that routine Doppler screening of the uterine arteries during the second trimester did not make an accurate prediction of fetal growth restriction, preeclampsia or preterm birth. However, we believe that the present study results prove that this screening may select a population with increased risk of adverse outcome, which would give them the opportunity to benefit from an early intervention.

The perioperative effect of anesthetic drugs on the immune response in total intravenous anesthesia in patients undergoing minimally invasive gynecological surgery.

BACKGROUND: The specific mechanism of action of each anesthetic drug on the immune system is still incompletely known. It is important to know how the various anesthetics used in minimally invasive surgery (MIS) act on the inflammatory response because the choice of the anesthetic agent can influence the patient's immune system. AIM: Evaluation of the effect of anesthetic drugs used for total intravenous anesthesia (Propofol and Midazolam) on the inflammatory response after minimally invasive gynecological surgery. PATIENTS, MATERIALS AND METHODS: The inflammatory response in 20 female patients who underwent minimally invasive gynecological surgery under which intravenous anesthesia was performed. Depending on the combination of anesthetics used, we subdivided the study group into two groups, Group 1 consisting of the patients (n=10) who were given for total intravenous anesthesia, the combination with Midazolam+Fentanyl, and Group 2 (n=10) the patients who received the combination of Propofol+Fentanyl, respectively. Surgical interventional procedures included day surgery: diagnostic and operative hysteroscopy, endometrial ablation, surgical treatment of vulvar disorders. Serological profiling of patients was performed by dosing the serum concentration of nucleotide-binding domain (NOD) and leucine-rich repeat protein 3 (NLRP3) inflammasomes, interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), IL-10 before and two hours after the surgical procedure. RESULTS: In our study, we found that in both groups of patients (Midazolam+Fentanyl - Group 1, Propofol+Fentanyl - Group 2), NLRP3 and cytokines concentrations in the serum were higher after MIS than those before MIS. CONCLUSIONS: It appears that both Midazolam and Fentanyl and Propofol and Fentanyl have an immunomodulatory action due to the anti-inflammatory effect of both anesthetics. Therefore, anesthesiologists must choose an anesthetic method that uses individualized anesthetic agents, depending on the patient's immune status and disease.

The potential value of diagnostic and predictive serum biomarkers for preeclampsia.

BACKGROUND: Preeclampsia (PE), one of the classes of hypertensive pregnancy disorders, is one of the three causes of maternal morbidity and mortality worldwide. The angiogenic and anti-angiogenic factors are useful markers in predicting and diagnosing PE. AIM: This study aims to detect and measure the serum level of some biomarkers [hypoxia-inducible factor-1 subunit alpha (HIF-1A), vascular endothelial growth factor (VEGF), interferon-gamma-inducible protein of 10 kDa (IP-10), matrix metalloproteinase-13 (MMP-13)] in patients with PE and their correlation with the severity of the disease, to find a good predictor for PE. PATIENTS, MATERIALS AND METHODS: This prospective study aims to monitor 48 pregnant women who address obstetric consultation and who present risk factors for PE, and a control group with characteristics similar to the study group. Patients were divided into three groups: Group I (n=15) including normal pregnant (NP) women with blood pressure <140∕90 mmHg, without proteinuria, Group II (n=18) including patients with mild PE (MildPE), Group III (n=15) including patients with severe PE (SeverePE). The analysis of serum biomarkers was based on a quantitative sandwich enzyme-linked immunosorbent assay (ELISA), according to the manufacturer's instructions. RESULTS: In our study, we found that all biomarkers investigated have higher concentrations in the serum of patients with SeverePE and MildPE than those in the control subjects (Group I, NP), the concentrations were increasing along with the disease activity. The means concentrations of HIF-1A, VEGF, IP-10, MMP-13, better correlated with indices in SeverePE group than in MildPE group. We found that VEGF was the biomarker that best correlates with indices that assess the severity of PE. The best separation of patients with SeverePE from those with MildPE can be done with the help of MMP-13 (82% accuracy), followed by VEGF (80.40% accuracy) and the least good detection being done by dosing IP-10. CONCLUSIONS: We can say that, due to high specificity diagnostic accuracy, determination of serum concentrations of MMP-13 and VEGF, could be useful in the diagnosis and distinguishing of patients with SeverePE and may prove useful in the monitoring of the disease course.

Relationship between Serum Leptin Values and Abdominal Circumference Assessed in the First Trimester of Pregnancy in Obese Women.

Higher serum leptin values have been correlated with several complications of pregnancy, while the abdominal circumference (AC) is an anthropometric measurement usually used to diagnose abdominal obesity. For this study we compared serum leptin levels between two groups of pregnant women: those with abdominal obesity (AC>88cm) and those without abdominal obesity (AC<88cm), diagnosed at the beginning of pregnancy. Serum leptin levels were obtained through measurements performed between 11-14 and 28-32 weeks of gestation. Higher serum leptin levels were found in the group of pregnant women with abdominal obesity comparing to the group without abdominal obesity, but a positive correlation between abdominal circumference and the leptin values was found only at 11-14 weeks of pregnancy. Our study showed that a simple measurement of AC performed at the beginning of pregnancy may predict the average serum levels of leptin throughout the gestation period. A better understanding of the role of leptin during development is needed to make us able to know how maternal-placental-fetal leptin exchange influence the fetal development.
