Etiology and perinatal outcomes between early and late-onset nonimmune hydrops fetalis.

OBJECTIVE: We aimed to compare the etiology and perinatal outcomes of non-immune hydrops fetalis diagnosed early- and late-onset at our hospital. METHODS: The records of the patients who applied to our department were reviewed, and we reached 42 non-immune hydrops fetalis cases retrospectively and examined the medical records. Hydrops diagnosis week, birth week, accompanying anomalies, and perinatal outcomes were compared as ≤12 weeks (early-onset) and >12 weeks (late-onset). RESULTS: The prevalence of non-immune hydrops fetalis was 0.05%, and the median week of diagnosis for hydrops was 18 weeks. Consanguinity (16.7%) was found in seven pregnancies, and the other seven patients (16.7%) had a history of hydrops in previous pregnancies. Anomalies of the skeletal system, central nervous system, and gastrointestinal tract accounted for 66.7% of ≤12 weeks in non-immune hydrops fetalis cases. Cardiac abnormalities were more common (26.7%) in patients at > 12 weeks (p=0.078). A statistically significant difference was found between the distribution of week of birth and week of diagnosis (p=0.029). Notably, 66.7% of patients diagnosed before week 12 and 23.3% of patients diagnosed after week 12 delivered their babies before week 24. Spontaneous intrauterine death occurred before week 12 in 45.5% (n=5) of non-immune hydrops fetalis and after week 12 in 39.1% (n=9) of non-immune hydrops fetalis. Notably, 69.2% (n=9) of the patients who had prenatal invasive testing resulted in normal karyotype. CONCLUSION: In this study, most of the fetuses diagnosed with early-onset non-immune hydrops fetalis were born in the first 24 weeks. Additionally, live birth rates and cardiac anomalies were observed to be higher in late-onset non-immune hydrops fetalis.

Use of Shock Index, Modified Shock Index, and Age-Adjusted Shock Index for Detection of Postpartum Hemorrhage.

PURPOSE: The aim of this study is to evaluate the role of shock index (SI), modified shock index (MSI), and delta shock index (ΔSI) in predicting postpartum hemorrhage (PPH) and adverse maternal outcomes. MATERIAL AND METHODS: In this cross-sectional cohort study, a study group consisting of 416 pregnant women who delivered at our hospital and had postpartum hemorrhage was compared with 467 control patients with normal follow-up. SI (pulse/systolic blood pressure), MSI (pulse/mean arterial pressure), ΔSI (input SI - 2nd- or 6th-hour SI) values were calculated. RESULTS: A total of 883 postpartum women were included in the study. The study group had higher peripartum, 2nd-hour, and 6th-hour SI values (p=0.011, p=0.001, p<0.001, respectively). Peripartum MSI values (p=0.004), 2nd-hour MSI values (p<0.001), and 6th-hour MSI values (p<0.001) were significantly lower in the control group than in the PPH group. When the groups were evaluated, the cut-off value of the 2nd-hour SI parameter was>0.8909 (sensitivity 30%, specificity 84%), and the 6th-hour SI parameter was>0.8909 (sensitivity 40%, specificity 80%) for predicting postpartum hemorrhage requiring blood transfusion and surgical intervention. The cut-off value of the 2nd-hour MSI parameter was>1.2 (sensitivity 34%, specificity 82%), and the cut-off value of the 6th-hour MSI parameter was>1.2652 (sensitivity 32%, specificity 90%). CONCLUSION: The 2nd- and 6th-hour SI and 2nd- and 6th-hour MSI values were significantly higher in patients with postpartum hemorrhage. Values greater than 0.89 for SI and 1.2 for MSI were considered significant for predicting postpartum hemorrhage with maternal impairment.

Does Second Trimester Maternal Serum Zonulin Level Predict Gestational Diabetes Mellitus?

Zonulin, a protein that regulates intestinal permeability, has attracted attention as a potential biomarker for GDM. Therefore, this study aims to investigate whether there are differences in zonulin levels between the GDM group and control groups, especially between those receiving different treatments (diet and insulin). Based on this idea, we included 90 patients with a gestational age between 24 and 28 weeks in our study. While GDM was not detected in 33 of these patients, as a result of OGTT, 57 patients were diagnosed with GDM and these patients were followed throughout their pregnancy. Gestational diabetes was diagnosed by an OGTT performed between 24 and 28 weeks of gestation according to American Diabetes Association (ADA) standards. During follow-up, GDM patients were divided into two groups according to whether they required insulin treatment. Plasma zonulin levels were determined using enzyme-linked immunosorbent assay (ELISA) techniques. The GDM group had significantly higher plasma zonulin levels than the control group (p < 0.005). According to our research, zonulin may be a non-invasive biomarker involved in the etiology of GDM. Large-scale research on this topic is still needed.

Liver damage parameters and peripheral blood parameters for prediction and diagnosis of intrahepatic cholestasis in pregnancy.

OBJECTIVE: Intrahepatic cholestasis of pregnancy (ICP) manifests in late pregnancy. Elevated serum bile acid is a diagnostic criterion: however, its measurement is troublesome. Prediction of ICP by blood markers is not established. Serum bile acid level is associated with liver damage and inflammation. We hypothesized that the following markers could predict the occurrence of ICP and have diagnostic value for it: Liver damage-indicating scores (albumin-bilirubin [ALBI], Model for End-Stage Liver Disease [MELD], aspartate aminotransferase-to-platelet ratio [APRI]) and inflammatory markers (platelet-to-lymphocyte ratio [PLR] and neutrophil-to-lymphocyte ratio [NLR]). METHODS: Eighty ICP patients and 200 controls were studied. The values of MELD, APRI, ALBI, PLR, and NLR were measured in the 1st trimester and at the time of diagnosis. RESULTS: Patients with ICP had significantly higher ALBI, MELD, and APRI scores both in the first trimester and at diagnosis. Multivariate logistic regression (MLR) showed that age, ALBI, MELD, and APRI scores were statistically significant (p < 0.05). By receiver operating characteristic (ROC) analysis, the sensitivity of MELD, ALBI, APRI, and NLR in the first trimester was 62%, 73%, 58%, and 29%, respectively, and MELD, ALBI, APRI, and PLR at diagnosis was 28%, 38%, 57%, and 8%, respectively, with a fixed false-positive rate of 10%. CONCLUSION: This study has demonstrated the usability of the MELD, ALBI, and APRI scores in predicting and diagnosing ICP. They are easy to obtain and might be used in routine practice.

Relationship between kisspeptin levels in the third trimester and late-onset fetal growth restriction: A case-control study.

INTRODUCTION: We aimed to investigate whether maternal serum kisspeptin levels are associated with late-onset FGR and contribute to adverse perinatal outcomes. METHOD: In this case-control study, a total of 90 pregnant women admitted to the perinatology clinic were enrolled. Forty-five of them were diagnosed with FGR and 45 women with healthy pregnancies formed the control group. Maternal serum levels of kisspeptin 1 were compared. RESULTS: Median kisspeptin1 serum levels were higher in the group of patients with FGR according to gestational age than in the control group [79.4(3.9-230.2) pg/mL vs. 39.8(0.4-188.3) pg/mL; p = 0.001]. The optimal cut-off value for kisspeptin1 was 30.32 pg/mL, with a positive predictive value of 64.6% (95% CI; 0.54-0.86), negative predictive value of 87.5% (95% CI; 0.44-0.72), positive likelihood ratio 1.75 (95% CI; 1.31-2.32), negative likelihood ratio 0.14 (95% CI; 0.04-0.44). DISCUSSION: Kisspeptin1 differed significantly in late-onset FGR compared with the control group. This difference from the control group can be used to estimate late-onset FGR.

The evaluation of serum brain-derived neurotrophic factor levels in pregnant women with hyperemesis gravidarum.

OBJECTIVES: The aim of this study was to investigate the relationship between levels of brain-derived neurotrophic factor (BDNF), which is considered a cause of conditions such as depression and eating disorders, and hyperemesis gravidarum (HG). MATERIAL AND METHODS: This study was conducted as a prospective study at Ankara Ataturk Training and Research Hospital in the Department of Obstetrics and Gynecology. The study included 73 pregnant women with singleton pregnancies (32 pregnant women with HG and 41 pregnant women without hyperemesis). Serum BDNF levels were compared between the two groups. RESULTS: The mean age of the study group was 27.3 ± 3.5 years and the body mass index (BMI) was 22.4 ± 2.7 kg/m². There is no statistically significant difference between the study group and the control group in terms of demographic data (p > 0.05). The pregnant women with HG were found to have significantly higher serum BDNF levels compared to the control group (349.1 ± 94.6 pg/mL vs 292. 3± 86.01, p = 0.009) CONCLUSIONS: Serum BDNF levels that are low in psychiatric disorders such as depression or anxiety were found as high in pregnant women with HG.

Evaluation of pregnancy and neonatal outcomes according to the phenotypic types of polycystic ovary syndrome: A prospective study.

OBJECTIVE: We aimed to compare pregnancy and neonatal outcomes in the phenotypic subtypes of patients with polycystic ovary syndrome (PCOS). METHODS: This prospective cohort included the patients with PCOS (n = 121) diagnosed according to the presence of androgen excess, ovulatory dysfunction, and/or polycystic ovary morphology and healthy controls (n = 125). We stratified PCOS as phenotype A (n = 45), phenotype B (n = 8), phenotype C (n = 32) and phenotype D (n = 35) and followed throughout pregnancy, comparing their outcomes. RESULTS: The study population had a mean age of 28.7 ± 4.9 years and a mean BMI of 31.6 kg/m2 with no difference between the groups. Primary cesarean deliveries were significantly more common in PCOS patients (23.3%) than in the control group (17.6%, P = 0.021). The phenotype A group had significantly higher rates of gestational diabetes mellitus (GDM) (42.2%, P < 0.001) and fetal macrosomia (14.6%, P = 0.002) compared with the control group (4.8% and 0.8%m respectively). We detected a significantly lower rate of normal risk score on the double screening test in the PCOS group (59.0%) than in the control group (75.4%) and in the other groups (P = 0.001). CONCLUSION: The rates of GDM, fetal macrosomia, and cesarean section were higher in the PCOS group, depending on the phenotype. We observed changes in risk calculation according to phenotypic types at aneuploidy screening.

Cysteinyl Leukotriene and Systemic Inflammatory Levels in Preeclampsia.

Background In this study, we aimed to demonstrate the efficacy of cysteinyl leukotriene levels, which play a role in inflammation, in predicting the severity of preeclampsia (PE) and to determine whether this marker can be used as a screening tool. Methods In this cross-sectional analytic study, we classified pregnant women who were normotensive (control) or PE or severe PE (SPE) between March 2019 and July 2019. Singleton pregnant 60 women who met the following criteria for the diagnosis of PE were included in the study group. We identified 30 patients with PE and 30 patients with SPE. Normotensive pregnant women (n=30) who met this criterion were included as a control group by randomly selecting them on odd days of the week. Results All pregnant women who participated in the study had a singleton pregnancy, and maternal age ranged from 18 to 40 years, with a mean age of 28.77±6.37 years. The mean gestational week of the group was 35.54±3.247 weeks. Gestational age was higher in women in the control group (p=0.018), shock index was higher in women in the control group (p < 0.001), and body mass index (BMI) value was lower in this group than in the other groups (p=0.002). The values of mean arterial pressure (MAP) were found to have a strong correlation with shock index value and a weak and negative correlation with gestational week and platelet/lymphocyte ratio (p < 0.05). The mean cysteinyl leukotriene levels of 206.15 pg/mL for the control group, 273.2 pg/mL for PE, and 211.85 pg/mL for SPE were calculated. However, no statistically significant difference was found between the groups (p=0.707). Conclusion We found that cysteinyl leukotrienes were not clinically important in assessing the risk for developing PE and predicting SPE. Alanine aminotransferase, white blood cell, lymphocyte, C-reactive protein, platelet/lymphocyte ratio, and shock index were positively correlated with the value of MAP.

Postoperative care in the caesarean intensive care unit: experience from a tertiary maternity hospital

Objective: The aim was to determine whether follow-up in the intensive care unit (ICU) for the postoperative first eight hours was beneficial for early intervention in postpartum hemorrhage. Material and Methods: In our hospital, all patients are admitted to the ICU for the first eight hours after cesarean section. Patients with postpartum hemorrhage after cesarean delivery who received medical and/or surgical treatment between 2016 and 2020 were reviewed in the presented study retrospectively. Results: All cases (n=36,396) who underwent cesarean delivery were reviewed. Three hundred and fifty-nine patients with postpartum hemorrhage were identified and included. In the study group the time between cesarean section and diagnosis of postpartum hemorrhage was 10.1±19.1 hours, and the time between cesarean section and re-laparotomy was 9.26±23.1 hours. A total of three maternal deaths occurred after cesarean section in our hospital. In the last five years, the mortality rate in patients delivering by cesarean section was 3.9 per 100,000. The incidence of postpartum hemorrhage in cesarean deliveries at our hospital was calculated to be 1.0%, and the rate of obstetric near-miss events was calculated to be 0.6 per 1000 live births. Conclusion: Follow-up of patients in the ICU in the first eight postoperative hours after cesarean section may result in a lower number of re-laparotomies due to postpartum hemorrhage, a shortened interval between cesarean section and re-laparotomy, and a lower maternal mortality rate.

Efficacy of blood parameters in predicting the severity of gestational hypertension and preeclampsia.

The aim of this retrospective study was to demonstrate the effectiveness of APRI, DNI, NLR, PLR, and PDW in predicting the severity of gestational hypertension (GHT) and PE and to determine whether these factors can be used as screening tools. Normotensive pregnant women (n = 792) served as the control group. 1,213 single pregnant women who met the following criteria for a GHT diagnosis were included in the study group. We found a significantly higher mean PLR and NLR value. The mean PDW value was significantly lower in the control group than in the other groups. The SPE group had a significantly higher mean APRI score. The groups did not differ by their DNI. We determined PDW and APRI as independent parameters that predicted SPE by multiple logistic regression analysis. In retrospective analysis of blood samples taken from these participants below week 20, we found that the APRI value differed significantly between the control and SPE groups. NLR, PLR, DNI, and PDW had no clinical significance. We further suggested that APRI may provide a clinical indication of progression from hypertensive pregnancy disorders to SPE, which seems to be a promising implication that should be verified by further studies.IMPACT STATEMENTWhat is already known on this subject? Hypertensive disorders in pregnancy are a major cause of maternal and perinatal morbidity and mortality. Screening pregnant women for risk factors for developing hypertensive disorders and identifying women at high risk in early pregnancy and initiating prophylactic treatment are important for pregnancy monitoring and planning in experienced centres. Because only 30% of women who will develop preeclampsia can be predicted by risk factors, the combined use of laboratory tests and imaging with risk factors to calculate a woman's risk of developing preeclampsia is currently being investigated. However, no proven marker has yet been found.What do the results of this study add? In our study, we found that NLR, PLR, DNI, and PDW have no clinical significance in assessing the risk of developing gestational hypertension and preeclampsia and in predicting the severity of preeclampsia. However, in our study, we found that APRI can provide a clinical indication of the progression of hypertensive pregnancy to SPE.What are the implications of these findings for clinical practice and/or further research? This study represents an important contribution to the literature because it is the first study to examine the association between APRI and HT in pregnancy.

A prospective study of myeloperoxidase levels in water immersion.

INTRODUCTION: We aimed to compare myeloperoxidase levels in cord blood samples of mothers undergoing water immersion or conventional labor. METHOD: We enrolled 52 pregnant women to this case control study meeting the following criteria: uneventful gestational follow-ups, no history of known chronic or pregnancy-associated diseases, cesarean section or uterine operation, BMI <29.9 kg/m2, single vertex presentation, normal fetal heart rate pattern, 37-41 weeks of gestation, estimated fetal weight of 2500-4000 g. The subjects were either undergoing immersion in water (n = 26) or conventional labor (n = 26) and their myeloperoxidase levels were measured from cord blood samples. RESULTS: The mean age of the study population was 24.55 ± 4.9 years. The mean BMI and weight gain during pregnancy were 26.8 ± 2.7 kg/m2 and 11.6 ± 5.3 kg, respectively. The mean age of gestation at birth was 39.6 ± 1.1 weeks, with a mean birth weight of 3205.5 ± 433.2 g. The subjects in water immersion and conventional labor groups showed no difference in terms of age, gestational age, BMI, and birth weight. The mean myeloperoxidase level was significantly lower in the water immersion group (759.8 ± 391.5 U/L) compared to that in the conventional labor group (1832.2 ± 1011.9 U/L, p = 0.004). DISCUSSION: Immersion in water during the first stage of labor seems to be associated with low myeloperoxidase levels, suggesting reduced oxidative stress in this delivery method.

A prospective study examining the effect of dienogest treatment on endometrioma size and symptoms.

OBJECTIVE: We aimed to determine the effect of dienogest on cyst volume, symptoms, and quality of life in patients with endometrioma. METHOD: This prospective cohort study included 37 patients diagnosed with endometrioma and planned for medical treatment. Subjects were treated with a 3-month oral dose of dienogest 2 mg/day. Pre-treatment and post-treatment endometriosis measurements were assessed via 3D ultrasonography, pain symptoms via 100-mm visual analog scale (VAS), and quality of life via Short Form-36. RESULTS: The mean age of the patients was 36.0 ± 6.6 years. The mean endometrioma volume was significantly reduced by 31% after treatment (26.7 ± 19.7 mm3) compared to the pre-treatment volume (17.4 ± 11.2 mm3, p < .001). Post-treatment VAS scores of dysmenorrhea, dyspareunia, and chronic pelvic pain VAS values were significantly decreased by 35.5% (p < .001), 37.5% (p < .001), and 38.5% (p < .001), respectively. The mean physical function score and mental health score significantly increased by 15% (p = .009) and 28% (p < .001), respectively. CONCLUSION: Our findings showed dienogest treatment at oral doses of 2 mg/day for 3 months significantly reducing the size of endometrioma, reducing pain level, and increasing quality of life in women with endometriosis.

Comparison of the Kisspeptin levels in early onset preeclampsia and late-onset preeclampsia.

OBJECTIVE: Maternal Kisspeptin plays role in cell migration which is responsible for trophoblast invasion. We aimed to investigate the role of Kisspeptin as an invasion marker in the early-onset and late-onset preeclampsia cases. STUDY DESIGN: In this case-control study, 125 patients were included: 20 patients with early-onset preeclampsia and 20 gestational-age-matched healthy controls; 45 patients with late-onset preeclampsia and 40 gestational-age-matched controls). Maternal plasma Kisspeptin concentration was measured and compared in groups regarding the presence of early-onset and late-onset preeclampsia. RESULTS: In the late-onset PE group, significantly higher maternal plasma Kisspeptin values were observed compared with the control group at > 34 weeks of gestation (68.7 ± 93.4 pg/ml vs 68.5 ± 57.9 pg/ml; p = 0.004). Before the 34th week of gestation, plasma Kisspeptin levels did not show a significant difference when patients with early-onset PE and gestational-age matched controls were compared (66.8 ± 87.9 pg/ml vs 48.5 ± 91.3 pg/ml; p = 0.56). CONCLUSION: Plasma Kisspeptin levels were significantly higher in women with late-onset preeclampsia, while no significant difference was observed in early-onset preeclampsia when compared with healthy gestational age-matched controls. The role of Kisspeptin proteins is still not clearly defined in the pathogenesis of preeclampsia.

Technique to reduce blood loss during open abdominal myomectomy: transverse or vertical incision?

OBJECTIVE: To determine if there is a difference between uterine incision techniques (vertical vs. transversal) in terms of clinical results. METHODS: All women with leiomyomas who underwent open abdominal myomectomy (n=61) between March and August 2016 at the Gynecology and Obstetrics Clinic at the Women's Health Research and Training Hospital Zekai Tahir Burak were included, and the clinical results were included and prospectively reviewed. RESULTS: The estimated blood loss during myomectomy increased in the transversal group compared with the vertical group (809.33±483.34 versus 405.32±180.95 mL, p<0.001). The average operation duration was 60 min, and the patients got discharged on the second day after surgery. No intergroup statistical differences were observed in the surgical procedure. CONCLUSIONS: Surgeons should give preference to the most viable incision depending on the size and location of the leiomyoma.

High Rate of Obstetric Complications in Patients With Essential Thrombocythemia.

Background Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm characterized by persistently elevated platelet count without a clear secondary cause. Although most patients with ET are between 55 and 60 years of age, it has been estimated that 20% of women with ET are diagnosed during reproductive ages. Miscarriage is the most frequent complication of ET that has been hypothesized to be caused by microcirculatory disturbances and placental microinfarction. Furthermore, pregnant patients with ET are at increased risk of other pregnancy complications such as preterm delivery and intrauterine growth restriction. Methods This study was planned to evaluate pregnancy outcomes and predictors of obstetric complications in pregnant women with essential thrombocythemia (ET). The data of 21 patients with ET were analyzed retrospectively between 2016 and 2020. Age, parity, history of miscarriage, presence of Janus kinase 2 (JAK2) mutation, history of thrombotic events, treatment of thrombocytosis during pregnancy, and obstetrical outcomes including miscarriage were compared. Results Patients with ET had a significantly higher rate of history of two or more previous miscarriages. Miscarriage and obstetric complications in pregnant women with ET were found to be significantly higher than in the control group. Patients with ET with obstetric complications or miscarriage more frequently had a platelet count of >1000 × 103/µL. Acetylsalicylic acid (ASA) prevented miscarriages, but not obstetric complications, in patients with ET. Conclusion ET increases miscarriage and obstetric complications in pregnancy. Treatment with ASA may reduce pregnancy losses, but not obstetric complications.

Association of Higher Maternal Serum Levels of Plac1 Protein with Intrauterine Growth Restriction.

The aim of this study was to determine the maternal PLAC1 protein levels in infants with IUGR. A total of 40 pregnant women with IUGR and 40 controls were recruited in this case control study between June 2014 and November 2014. Maternal serum PLAC1 levels were established as significantly higher in IUGR cases compared to the control groups (8.42±3.59 ng/ml vs. 6.27±4.04 ng/ml, p<0.001). Area under ROC curve (AUC) analysis of PLAC1 in IUGR was 0.708, (95% confidence interval (CI): 0.593-0.823, p=0.001) (Figure 1). Maternal PLAC1 levels above 7.41 ng/ml had a sensitivity of 62.5% (95% C1: 45.81-76.83), a specificity of 77.5% (95% CI: 61.15-88.6); positive and negative predictive values (PPV and NPV) were 73.53% (95% CI: 55.35-86.49) and 67.39% (95% CI: 51.86-80.03), respectively, with a diagnostic accuracy of 70%. In conclusion, we were able to demonstrate a significantly important link between IUGR and higher maternal serum levels of the PLAC1 protein.

Maternal placi protein levels in early- and late-onset preeclampsia.

OBJECTIVES: The objective of this study was to determine the maternal PLAC1 protein levels in early and late onset preec-lampsia. MATERIAL AND METHODS: A total of 135 pregnant women were included in the study, of which 55 were at < 34 weeks of gesta-tion and 80 were at ≥ 34 weeks of gestation, between June and November 2014 were recruited in this case control study. RESULTS: Analysis of maternal serum PLAC1 levels did not reveal any significant differences between early onset PE and controls (p = 0.422). However, late onset PE patients exhibited significantly elevated levels of PLAC1, in comparison with healthy controls (p = 0.026). The difference in PLAC1 levels between early onset PE and late onset PE was also significant (p = 0.001). Area under ROC curve of PLAC1 for early and late onset PE was 0.563 and 0.646 with p values of 0.422 and 0.026 respectively. Area under ROC curve of PLAC1 in PE was 0.613 with p value = 0.024. The cutoff value for PLAC1 was 6.19 ng/mL with sensitivity: 56% (95% CI 44.1-67.3) and specificity: 63 %; (95% CI 49.9-75.1) and diagnostic odds ratio: 2.2 (95% CI 1.1-4.4) (p value = 0.037). The cutoff value for PLAC1 was 7.2 ng/mL with sensitivity: 43% (95% CI 31.5-54.6) and specificity: 78% (95% CI 65.5-87.5) and diagnostic odds ratio: 2.69 (95% CI 1.25-5.79) (p value = 0.016) CONCLUSION: In conclusion, the results of the current study showed that PLAC1 protein levels were significantly elevated in pregnant women with late onset PE in comparison with healthy control group.
