The predictive role of second trimester uterocervical angle measurement in obstetric outcomes.

Objective: Uterocervical angle has been suggested as a marker to predict preterm birth. However, the literature has limited data about its predictive role in preterm delivery. Moreover, no evidence is present to clarify the role of second-trimester uterocervical angle in induction success and postpartum hemorrhage. Here, it was aimed to compare the role of uterocervical angle with cervical length in predicting preterm labor and assess the utility of the second-trimester uterocervical angle in induction success and postpartum hemorrhage. Materials and Methods: A total of 125 pregnant women, hospitalized with a diagnosis of preterm labor were included in the study. Sonographic measurements of cervical length and uterocervical angle were performed between 16 and 24 weeks of gestation. The demographic, obstetric, laboratory, and sonographic features of the participants were recorded. Patients were divided into subgroups as preterm and term; with and without induction success; with and without postpartum hemorrhage. Additionally, preterm cases were divided into subgroups as early and late preterm. Variables were evaluated between the groups. Results: Cervical length was shorter in the preterm group (30.74±6.37 and 39.19±5.36, p<0.001). The uterocervical angle was 100.85 (85.2-147) in preterm and 88 (70-131) degrees in terms that were statistically significant (p<0.001). Furthermore, the uterocervical angle was wider [126 (100.7-147) and 98 (85.2-114), p<0.001] in the early preterm group. When the groups with and without postpartum bleeding were compared, no significant difference was detected in terms of uterocervical angle [96.5 (71-131) and 88 (70-147), p=0.164]. Additionally, the uterocervical angle was wider in the successful induction group (p<0.001). An a uterocervical angle >85 degrees predicted preterm delivery with 100% sensitivity and 45.54% specificity [area under the curve (AUC)=0.743, p<0.001]. When the cervical length and uterocervical angle were evaluated together to predict preterm delivery, no significant difference was found (p=0.086). An a uterocervical angle >88 degrees predicted induction success with 84.78% sensitivity and 79.75% specificity (AUC=0.887, p<0.001). Conclusion: Our study revealed that the uterocervical angle can be a useful marker in predicting preterm labor and induction success, although it does not predict postpartum hemorrhage.

The role of oligohydramnios and fetal growth restriction in adverse pregnancy outcomes in preeclamptic patients.

OBJECTIVES: We aimed to compare perinatal outcomes of oligohydramnios or fetal growth restriction with normal amniotic fluid index and fetal growth in preeclampsia and to compare the outcomes of only oligohydramnios, only fetal growth restriction and oligohydramnios with fetal growth restriction preeclamptic groups. MATERIAL AND METHODS: A total of 743 preeclamptic patients were evaluated between June 2016 and 2020. Patients were divided into two groups: preeclampsia with oligohydramnios or fetal growth restriction (n = 237) and preeclampsia with normal amniotic fluid index and fetal growth (n = 506). Then, the first group was divided subgroups as only oligohydramnios (n = 55), only fetal growth restriction (n = 125) and oligohydramnios with fetal growth restriction (n = 57). Demographic characteristics and perinatal outcomes were recorded. RESULTS: Gestational age at delivery (p < 0.001), birth weight (p < 0.001), Apgar scores (p < 0.001) and eclampsia (p < 0.001) were lower whereas impaired doppler findings (p < 0.001), cesarean rates (p < 0.001), preterm delivery (p < 0.001), abruptio placenta (p < 0.001), acute fetal distress (p < 0.001), RDS (p < 0.001), NICU requirement (p < 0.001) and neonatal death (p < 0.001) were higher in oligohydramnios or fetal growth restriction preeclamptic group. In subgroup analysis, there were differences between three groups according to the gestational age (p < 0.001), cesarean rates (p = 0.002), preterm delivery (p < 0.001), intensive care unit requirement (p = 0.039), birth weight (p < 0.001), Apgar scores (p < 0.001), RDS (p < 0.001) and NICU requirement (p < 0.001). In pairwise comparison, there was significant difference between only oligohydramnios and only fetal growth restriction group and between only oligohydramnios and oligohydramnios with fetal growth restriction group according to birth weight, Apgar scores, preterm delivery and cesarean rates, presence of RDS, maternal and neonatal intensive care unit requirement. No significant difference was detected between only fetal growth restriction group and oligohydramnios with fetal growth restriction group in terms of all parameters. CONCLUSIONS: We suggest that patients with only oligohydramniosis have more favorable pregnancy outcomes than pregnants with only fetal growth restriction and coexistence of two conditions in preeclamptic patients. We claim that it could be appropriate to recommend close monitorization in preeclamptic patients with only fetal growth restriction and oligohydramniosis and fetal growth restriction.

Assessment of relationship between serum vascular adhesion protein-1 (VAP-1) and gestational diabetes mellitus.

Purpose: VAP-1 plays a crucial role in inflammation, oxidative stress and endothelial dysfunction which are main pathophysiologic mechanisms for gestational diabetes. We aimed to determine serum VAP-1 levels, assess its diagnostic value and correlation with clinical parameters in gestational diabetes.Methods: A total of 60 pregnant women with gestational diabetes and 75 healthy pregnant women between 24-28th gestational weeks between January-June 2017 were included. Pregnant women were screened for gestational diabetes by two-step protocol. Demographic, clinical and laboratory parameters of patients were recorded. VAP-1 was measured using an enzyme-linked immunosorbent assay method.Results: Gestational diabetes group had higher fasting and postprandial glucose, HbA1c, neutrophil-to-lymphocyte-ratio, platelet-to-lymphocyte-ratio, plateletcrit and C-reactive protein. Furthermore, VAP-1 levels were higher in gestational diabetes (3.35 ± 1.52 vs 2.2 ± 0.74; p < 0.001). VAP-1 levels >2.315 could predict gestational diabetes with a sensitivity of 70% and specificity of 65.3%. VAP-1 was correlated with clinical follow-up parameters such as fasting glucose (r = 0.473, p < 0.001), postprandial glucose (r = 0.416, p < 0.001), HbA1c (r = 0.462, p < 0.001) and inflammatory biomarkers such as platelet-to-lymphocyte-ratio (r = 0.254, p = 0.04), neutrophil-to-lymphocyte-ratio (r = 0.375, p = 0.003) and C-reactive protein (r = 0.306, p = 0.017).Conclusions: Elevated VAP-1 levels in gestational diabetes correlated with clinical follow-up and inflammatory markers may suggest the pathogenetic role of VAP-1 in gestational diabetes. Hence, we think that VAP-1 could be a promising marker for the prediction of gestational diabetes.

Laparoscopic versus vaginal cuff closure in laparoscopic hysterectomy: does it affect female sexuality?

OBJECTIVES: To investigate the effect of vaginal cuff closure technique in laparoscopic hysterectomy on vaginal length and female sexual functions. MATERIAL AND METHODS: This study was conducted at a tertiary research hospital. Women who underwent laparoscopic hysterectomy were included and classified according to vaginal cuff closure technique as laparoscopic (n = 75) and vaginal route (n = 25). Vaginal lengths were measured preoperatively and at 6th month postoperatively. Golombok-Rust Inventory of Sexual Satisfaction (GRISS) was used to evaluate female sexual functions. SPSS was used for statistical analysis and the level of significance was p = 0.05. RESULTS: Preoperative GRISS scores and vaginal lengths were similar in two groups. The shortening of vaginal length and the worsening of GRISS scores were more prominent in vaginal cuff closure group (p = 0.002, p < 0.001). The alteration in vaginal length was positively correlated with the alteration in GRISS score in vaginal and laparoscopic route groups (r = 0.800, p < 0.001; r = 0.680, p < 0.001). The risk of female sexual dysfunction increases 69.88 fold for each 1 cm shortening of vaginal length (p = 0.039). Discriminative value of postoperative vaginal length for female sexual dysfunction in patients who underwent laparoscopic hysterectomy was investigated and a cut-off value of 7.4 cm (p < 0.001) was found. CONCLUSIONS: Laparoscopic route instead of vaginal route in laparoscopic hysterectomy is preferable to preserve a better vaginal length, which may be an important factor for female sexual functions.

P-wave and QT dispersion in hypertensive disorders of pregnancy.

Aim: To compare P-wave and QT dispersion values in hypertensive disorders of pregnancy and controls and also in preeclampsia, chronic hypertension, and gestational hypertension separately.Material and methods: We included 140 hypertensive pregnants and 110 healthy age-matched pregnants in this study. The hypertensive pregnants were divided into three subgroups: preeclampsia (n = 43), chronic hypertension (n = 51), and gestational hypertension (n = 46). P-wave and QT dispersion values were compared between groups.Results: Hypertensive pregnants had higher P-wave (41.74 ± 5.51 vs. 37.73 ± 5.62, p < .001) and QTc dispersion (45.44 ± 7.62 vs. 39.77 ± 8.34, p < .001) values. In subgroup analysis, P-wave dispersion and QTc dispersion were different between preeclamptic, chronic hypertensive, and gestational hypertensive patients. Also, they were significantly higher in chronic hypertension as compared to gestational hypertension and they were higher in preeclampsia than in gestational hypertension. No difference was found according to these parameters between preeclampsia and chronic hypertension. In correlation analysis, both P-wave dispersion and QTc dispersion were positively correlated with systolic (r = 0.409, p < .001 and r = 0.306, p < .001) and diastolic blood pressure (r = 0.390, p < .001 and r = 0.287, p < .001) which are main clinical determinants of hypertensive disorders.Conclusion: In clinical practice, chronic hypertensive pregnants are generally followed up in their future life for cardiovascular disorders. Also, we recommend that we must inform and follow preeclamptic patients for future cardiovascular diseases.

TWEAK and monocyte to HDL ratio as a predictor of metabolic syndrome in patients with polycystic ovary syndrome.

We aimed at analyzing serum TWEAK levels and monocyte/HDL ratio in polycystic ovary syndrome (PCOS) and their predictivity for metabolic syndrome (MS) in PCOS. We included 71 women with PCOS and 40 healthy controls without any cardiovascular risk factors in this cross-sectional study. Patient group was classified as MS positive (n = 34) and negative (n = 37). Study group had higher monocyte/HDL ratio and TWEAK levels (9.59 ± 2.82 vs 8.2 ± 2.46, p = .007 and 1085.54 ± 780.95 vs 694.88 ± 369.67 ng/ml, p = .009). Monocyte/HDL ratio and TWEAK levels were higher in MS positive group (10.47 ± 2.81 vs 8.77 ± 2.61, p = .01 and 1417.59 ± 921.52 vs 780.41 ± 455.67, p = .009). In multivariate regression analysis, monocyte/HDL ratio (>9.9, OR 3.42, 95%CI 1.41-5.78, p = .008) and TWEAK (>846.5 ng/ml, OR 5.49, 95%CI 3.14-7.59, p = .002) were found to be independent predictors of MS in study group. Discriminative value of monocyte/HDL ratio for MS in study group was evaluated by receiver operating curve. Area under curve for monocyte/HDL ratio was 0.669 with a sensitivity of 70.3% and specifity of 67.7%, cutoff value was >9.9. Receiver operating curve for TWEAK at >846.5 pg/ml threshold to diagnose MS in study group was performed and area under the curve was 0.769 with a sensitivity of 73% and specifity of 72%. TWEAK and monocyte/HDL ratio may be promising in predicting MS at early stages in PCOS to prevent future cardiovascular diseases by modifying life-style or giving pharmacotheraphy.

The effect of first trimester hemoglobin levels on pregnancy outcomes.

OBJECTIVE: The relationship between hemoglobin levels and pregnancy outcomes is still a challenging issue. There is a supported opinion about the increased adverse pregnancy outcomes both with low and high hemoglobin levels. In this study, we aimed to evaluate this association for first trimester hemoglobin levels in a Turkish population. MATERIALS AND METHODS: In this retrospective study, 1306 women who were followed up during their pregnancy and gave birth in our clinic were enrolled. The patients were divided into three groups: hemoglobin <11 g/dL (n=490), 11≤ hemoglobin <13 g/dL (n=673), and hemoglobin ≥13 g/dL (n=143). The hemoglobin <11 g/dL group was classified into two subgroups as hemoglobin ≤9 g/dL (n=64) and hemoglobin >9 g/dL (n=426). Demographic characteristics, first trimester hemoglobin levels, gestational age at delivery and mode, birth weight, Apgar scores, and pregnancy outcomes were recorded and compared between the groups. RESULTS: Pregnancy-induced hypertension, preterm birth, neonatal intensive care unit admission, birth weight, gestational age at delivery, Apgar scores, and postpartum hemorrhage were significantly different between the three groups. In the pairwise comparison, gestational age at delivery, birth weight, and first minute Apgar scores were higher in the 11≤ hemoglobin <13 g/dL group, and pregnancy-induced hypertension was more common in the hemoglobin ≥13 g/dL group as compared with the others. Moreover, the preterm delivery rate was highest in the hemoglobin ≥13 g/dL (26.6%) group and lowest (7.3%) in the 11≤ hemoglobin <13 g/dL group. The neonatal intensive care unit admission rate was higher both the hemoglobin <11 g/dL and hemoglobin ≥13 g/dL groups. Postpartum hemorrhage was more common in the hemoglobin <11 g/dL group as compared with the other groups. Furthermore, pregnancy-induced hypertension was more common in the hemoglobin ≤9 g/dL subgroup (p=0.012). CONCLUSION: In conclusion, both low and high hemoglobin levels are related with adverse pregnancy outcomes. We suggest that hemoglobin levels must be screened during pregnancy to provide maternal and fetal well-being.

Is pregnancy associated plasma protein-A (PAPP-A) a marker for adverse perinatal outcomes in preterm isolated oligohydramnios cases?

OBJECTIVE: Isolated oligohydramnios is defined as an amniotic fluid index below five centimeter with no other coexisting condition. There are still controversies about the management and pregnancy outcomes. A marker predicting these is crucial. Low pregnancy associated plasma protein-A levels were reported to be related with adverse pregnancy outcomes. We aimed to determine the role of first trimester pregnancy associated plasma protein-A for poor outcomes in preterm isolated oligohydramnios cases. MATERIAL AND METHODS: Fifty-one patients with singleton pregnancies diagnosed as isolated oligohydramnios at 28/0-36/6 weeks of gestation and 110 gestational age matched healthy controls between January and December 2015 were included. Maternal age, gestational age at delivery, mode of delivery, indication for cesarean section, Apgar scores at first and fifth minutes, birth weight, neonatal intensive care unit admission and mortality were recorded. Pregnancy associated plasma protein-A levels were compared between groups and its role in adverse perinatal outcomes was evaluated. RESULTS: Pregnancy associated plasma protein-A levels and pregnancy outcomes were similar in two groups (p > 0.050) except birth weight, gestational age at delivery and presence of fetal distress. Pregnancy associated plasma protein-A levels did not differ in terms of delivery mode, presence of fetal distress, first and fifth minutes Apgar scores and neonatal intensive care unit admission (p = 0.323,0.650,0.990,0.112,0.853). Also, it was not determined as a risk factor for cesarean section, presence of fetal distress, low Apgar scores and neonatal intensive care unit admission. CONCLUSION: Pregnancy associated plasma protein-A, a well-known prognostic factor for some of high risk pregnancy conditions, may not be used as a marker in preterm isolated oligohydramnios cases.

Platelet indices in preterm premature rupture of membranes and their relation with adverse neonatal outcomes.

AIM: Preterm premature rupture of membranes (PPROM) is not only the most common distinguishable cause of preterm delivery, but is also associated with adverse neonatal outcomes. We determined the platelet indices in PPROM cases and evaluated their relationship to adverse neonatal outcomes. METHODS: Fifty patients with PPROM and 50 patients who experienced spontaneous preterm labor at < 37 gestational weeks were evaluated. Complete blood counts, birth weights, Apgar scores, presence of sepsis and respiratory distress syndrome (RDS) and neonatal intensive care unit admission were recorded. RESULTS: Patients with PPROM had increased mean platelet volumes (9.40 vs 10; P = 0.01), plateletcrit (0.19 vs 0.21; P = 0.03) and a higher frequency of neonatal sepsis (18% vs 38%; P = 0.02). Platelet indices in the patient group were compared according to the development of RDS. Plateletcrit values were higher in the RDS positive group (0.23 ± 0.05 vs. 0.21 ± 0.04; P = 0.04). The cut-off value for plateletcrit was determined as > 0.22, and the probability of RDS increased 5.86 times when plateletcrit values exceeded 0.22 (odds ratio 5.86, 95% confidence interval 1.01-32.01; P = 0.04). A one-unit increase in platelet distribution width resulted in a 1.33-fold increase in the risk of RDS (odds ratio 1.33, 95% confidence interval 1.01-1.77; P = 0.04). CONCLUSION: Mean platelet volumes and plateletcrit significantly increased and plateletcrit had a predictive value for RDS in PPROM cases. Monitoring plateletcrit may be promising for predicting the development of RDS, one of the most common and serious complications of PPROM rupture.

Maternal serum glycodelin levels in preeclampsia and its relationship with the severity of the disease.

PURPOSE: Preeclampsia, in which insufficient trophoblastic invasion is thought to be one of the underlying mechanisms, is a common pregnancy disorder. Glycodelin is a regulator of immunosuppression, fertilization, implantation, and placentation. Because of its inhibitory effects on trophoblastic activity, trophoblast invasion is disturbed when its levels alter. We aimed to analyze serum glycodelin levels in preeclampsia and evaluate whether it correlates with the severity of disease. METHODS: This is a prospective case-control study conducted in a research and training hospital between March and September 2016. In this study, a total of 55 preeclamptic and 65 healthy pregnants were included. Preeclamptic patients were divided into two subgroups: 25 severe and 30 mild. Maternal serum glycodelin levels were measured using enzyme-linked immunosorbent assay. RESULTS: Glycodelin levels were higher in preeclamptic group as compared with controls (71.38 ± 22.78 versus 42.32 ± 12.28 ng/ml, p < .001). Also, it was higher in severe preeclampsia than the mild group (84.19 ± 24.58 versus 60.71 ± 14.4 ng/ml, p < .001). Glycodelin was positively correlated with systolic and diastolic blood pressures (r = 0.637 and r = 0.714, respectively, p < .001), aspartate and alanine aminotransferases (r = 0.369, p = .006 and r = 0.377, p = .005) and proteinuria (r = 0.342, p = .011). Moreover, it was correlated with birth weights and gestational age at delivery (r = -0.386, p = .004 and r = -0.394, p = .003, respectively). The role of glycodelin to diagnose preeclampsia was evaluated by receiver operating curve (ROC) curve. Area under the curve for glycodelin is 0.897 with p < .001. The sensitivity of glycodelin was 83.6% and the specificity was 80% at a threshold >53.64 ng/ml. Moreover, area under the curve for glycodelin to diagnose severe preeclampsia is 0.788 with p < .001. The sensitivity of glycodelin was 59% and the specificity was 93.3% at a threshold >83.97 ng/ml. CONCLUSION: Glycodelin may be a promising marker in predicting the presence and severity of preeclampsia.

Increased serum neuregulin 4 levels in women with polycystic ovary syndrome: A case-control study.

Neuregulin 4 (NRG4) is an adipokine that is synthesized in many tissues and has been shown to be associated with the development of obesity and metabolic disorders in animals and humans. The aim of this study is to investigate the relationship between serum NRG4 levels and various metabolic parameters in women with PCOS. This cross-sectional study included 40 women with PCOS and 40 age- and BMI-matched controls without PCOS. NRG4, fasting blood glucose (FBG), insulin, hs-CRP, LDL-C, HDL-C, SHBG, DHEA-SO4 and total-testosterone levels were measured in all the participants. HOMA-IR was used to calculate the insulin resistance. Serum NRG4 levels were higher in women with PCOS than in healthy women (24.89 ± 9.32 [ng/mL] vs. 18.98 ± 6.40 [ng/mL], p = 0.002). FBG, LDL-C, HDL-C, LH, SHBG, FAI, DHEA-SO4, insulin, hs-CRP, HOMA-IR and total-testosterone levels were significantly higher in women with PCOS than controls. Circulating NRG4 levels were positively correlated with HOMA-IR, insulin and hs-CRP for both groups. There was a positive correlation between NRG4 and FBG in the PCOS group. HOMA-IR and hs-CRP were associated with NRG4. The high concentration of circulating NRG4 in PCOS may be associated with insulin resistance and low-grade chronic inflammation.

Platelet-to-lymphocyte ratio: A new inflammatory marker for the diagnosis of preterm premature rupture of membranes.

OBJECTIVE: Preterm premature rupture of membranes (PPROM) is closely related with maternal and fetal complications. Therefore, early diagnosis is extremely important to provide maternal and fetal well-being. Many inflammatory markers have been evaluated for their ability to diagnose membrane rupture at early stages. We aimed to investigate the relationship between the platelet-to-lymphocyte ratio (PLR) and preterm premature membrane rupture. MATERIAL AND METHODS: In this study, 121 pregnant women with PPROM and 96 age-matched pregnant women with spontaneous preterm labor who were admitted to our hospital between January 2014 and December 2015 were enrolled. Demographic data, complete blood cell count results, and neonatal outcomes were recorded. RESULTS: The neutrophil and platelet counts were higher in the PPROM group (9948.4±3393.2 vs. 7466.1±1698.5/mm3 and 244.5±60 vs. 210.6±64.8/mm3, respectively, p<0.001). The PLR and neutrophil-to-lymphocyte ratios (NLR) were both significantly higher in the PPROM group (p<0.001). Correlation analysis revealed that the PLR was positively correlated with the NLR (r=0.10, p=0.031). The ability of the PLR to diagnose preterm premature rupture of membranes was evaluated using an ROC curve. The sensitivity and specificity of the PLR was 57.8% and 73.7%, respectively, at a threshold >117.14 (p<0.001). CONCLUSION: The PLR might be a cost effective, easy to use, and practical marker for the early diagnosis of PPROM, which can help to determine the appropriate waiting time for delivery and provide maternal and fetal well-being.

Assessment of relationships between novel inflammatory markers and presence and severity of preeclampsia: Epicardial fat thickness, pentraxin-3, and neutrophil-to-lymphocyte ratio.

OBJECTIVE: The aim of this study was to evaluate the relation of three new inflammatory markers with presence and severity of preeclampsia and to compare the predictive values of all markers for presence of this setting. METHODS: In this study, a total of 100 consecutive pregnants with a diagnosis of preeclampsia and 40 healthy pregnants between October 2014 and April 2015 were included. Epicardial fat tissue was calculated by two-dimensional transthoracic echocardiography, and pentraxin-3 and neutrophil-to-lymphocyte ratio were measured by using an enzyme-linked immunosorbent assay method and routine blood count analysis, respectively. RESULTS: Epicardial fat thickness (p < 0.001), pentraxin-3 (p < 0.001), and neutrophil-to-lymphocyte ratio (p < 0.001) were found to be significantly increased in the preeclampsia as compared to the healthy pregnants. Furthermore, epicardial fat thickness (p = 0.002), pentraxin-3 (p < 0.001), and neutrophil-to-lymphocyte ratio (p < 0.001) were significantly elevated in the severe preeclampsia compared to mild preeclampsia. In the multivariate analysis, epicardial fat thickness (p = 0.013), pentraxin-3 (p = 0.04), and neutrophil-to-lymphocyte ratio (p < 0.001) were found as significant independent predictors of presence of preeclampsia after adjusting for other risk factors. CONCLUSION: Epicardial fat thickness, neutrophil-to-lymphocyte ratio, and pentraxin-3 are important markers that provide an additional information beyond that provided by conventional methods in predicting presence and severity of preeclampsia.

Scimitar syndrome and pregnancy, complicated with severe preeclampsia.

Scimitar syndrome (pulmonary venolobar syndrome) is a rare anomaly of venous return to the heart, most commonly consisting of partial or total anomalous pulmonary venous return from the right lung. This is the report of a case of a 29-year-old woman at 31 weeks of gestation of pregnancy who was previously diagnosed with scimitar syndrome. MR angiography and PET-CT results which were obtained before pregnancy demonstrated vascular malformation in the inferior part of the right lung. No specific treatment was planned throughout the pregnancy due to the absence of any symptoms. The patient's first physical examination was unremarkable except mild hypertension. In her follow-up, severe preeclampsia was developed and the patient had undergone a cesarean section of a live birth at 34 weeks and 2 days of gestation. This is the first case of scimitar syndrome with pregnancy in which the cardiac status of the patient deteriorated coincidentally due to the development of another manifestation such as severe preeclampsia besides the syndrome itself.
