Background: Subfatin, a newly discovered adipokine, plays a pivotal role in the regulation of glucose metabolism. The relationship between gestational diabetes mellitus and maternal dyslipidemia is well-documented., Aims: This study aims to assess serum subfatin levels and the triglyceride/high-density lipoprotein cholesterol ratio in women with one abnormal glucose tolerance test value and those with gestational diabetes mellitus., Methods: In this case-control study, 105 pregnant women were categorized into three groups: women with normal 3-h oral glucose tolerance test results (n=35), women with one abnormal 3-h oral glucose tolerance test result (n=35), and women diagnosed with gestational diabetes mellitus (n=35). Serum subfatin levels were measured using human enzyme-linked immunosorbent assay kits., Results: Serum subfatin levels were significantly lower in the gestational diabetes mellitus group (0.94±0.15 ng/mL) compared to the normal oral glucose tolerance test group (1.48±0.55 ng/mL) and the group with one abnormal oral glucose tolerance test result (1.50±0.59 ng/mL). The triglyceride/high-density lipoprotein cholesterol ratio was also lower in the healthy control group than in the gestational diabetes mellitus and one abnormal oral glucose tolerance test result groups., Conclusion: Serum subfatin levels in women with one abnormal abnormal glucose tolerance test value are compared to those in the control group, while the triglyceride/high-density lipoprotein cholesterol ratio is significantly altered in women with one abnormal abnormal glucose tolerance test value when compared to the control group.

Objective: The pathophysiology of uterine scar dehiscence is not yet clear. The aim of this study was to investigate whether preoperative hemogram parameters can be used as predictive markers of uterine scar dehiscence, thus improving prediction and contributing to management of repeat Cesarean section., Material and Methods: Between 2015 and 2020, 36670 (47.6%) cesarean sections were delivered in our hospital and 16943 of them had a previous Cesarean section. All cases of uterine scar rupture detected during Cesarean section were identified, and a total of 40 patients were included after excluding cases with impairment of the systemic inflammatory response (SIR). Controls consisted of 40 randomly selected, age-and body mass index (BMI)-matched patients, and the groups were compared., Results: Age, BMI, and gravidity were similar (p>0.05). Although the gestational week and Apgar scores were similar between the groups (p>0.05), the birth weight amongst controls was significantly higher than the uterine dehiscence group (p=0.028). Platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, and other hemogram values were similar in both groups (p>0.05). Mean platelet volume (MPV) in the control group was significantly higher than in the uterine rupture group (p=0.049). Regression analysis found no significant result between hemogram parameters, birth weight, and dehiscence., Conclusion: In this study, which set out to identify predictors of the risk of uterine scar dehiscence with SIR parameters, only the MPV value was lower in the dehiscence group., Competing Interests: Conflict of Interest: No conflict of interest is declared by the authors., (Copyright© 2024 The Author.

Objectives: To evaluate the maternal serum ischemia-modified albumin (IMA) concentration as an oxidative stress biomarker in pregnancies complicated by preterm pre-labor rupture of membranes (PPROM) without maternal clinical infection and compare these results with healthy pregnancies., Material and Methods: The present cohort study included 40 pregnancies complicated by PPROM and 49 similar gestational age healthy pregnancies in the third trimester of gestation. Maternal venous blood specimens were obtained at the day of first diagnosis. Maternal serum IMA level was assayed with an Albumin Cobalt Binding test. The subjects were followed up until delivery and perinatal outcomes were recorded., Results: The maternal serum IMA concentrations were significantly higher in the study group (0.56 ± 0.05 absorbance units) as compared to controls (0.54 ± 0.03 absorbance units) (p = 0.020). The maternal serum IMA concentrations were not significantly correlated with the initial maternal white blood cell count (r: 0.118, p = 0.269) and C-reactive protein levels (r: 0.066, p = 0.541). The maternal serum IMA concentrations were negatively correlated with gestational age at delivery (r: -0.248, p = 0.019), birthweight (r: -0.247, p = 0.020) and Apgar scores (r: -0.200, p = 0.049; r: -0.245, p = 0.020). The threshold value of maternal serum IMA concentration above 0.55 absorbance units indicated the pregnancy complicated by PPROM by 57.5% sensitivity and 57.1% specificity (Area under curve 0.613, confidence interval 0.50-0.73)., Conclusions: The current study supported for the first time that there is an association between increased maternal serum IMA levels and the development of PPROM in the third trimester of gestation without maternal clinical infection. Elevated maternal serum IMA levels may alert the obstetrician about poor ongoing perinatal outcomes in the early phase of PPROM before increased maternal C-reactive protein and white blood cell count.

Objective: To determine the characteristics and subsequent pregnancy outcomes in patients with a previous ectopic pregnancy (EP)., Study Design: Descriptive-cross sectional study., Place and Duration of Study: Department of Obstetrics-Gynaecology, Etlik Zubeyde Hanim Maternity and Women's Health Teaching and Research Hospital, Ankara, Turkey, between January 2014 and December December 2018., Methodology: The data of nulliparous patients diagnosed with tubal ectopic pregnancy (EP) was analysed retrospectively. Reproductive outcomes within the first two years after ectopic pregnancy diagnosis were used as "short-term" reproductive outcomes. Their EP treatment and pregnancy outcome were determined., Results: Expectant management was chosen in 5.8% of the patients, while the surgical intervention was 32.3%. Medical therapy involving methotrexate (MTX) was given to the remaining patients (61.9%). The tubal rupture was confirmed in 12% of the cases that received MTX. In the 2-year follow-up period after the ectopic event, the most common outcome of the subsequent pregnancies was a live birth (47.7%). Recurrent EP occurred in 4.6%., Conclusion: The subsequent short-term pregnancy outcomes in this study were not related to the chosen treatment modality., Key Words: Ectopic pregnancy, Nulliparity, Reproductive outcomes, Treatment modalities, Expectant management.

Purpose: Disease progress may be affected by pregnancy-related changes, and underlying conditions may also affekt pregnancy outcomes in women with Gitelman syndrome (GS). Case presentation A 35-year-old woman with GS (gravida 2 para 1) was referred to our hospital to start routine antenatal care follow-up at 6 weeks of gestation. At the age of 31, she had been diagnosed with GS after her first uneventful pregnancy. Upon early admission, her serum Mg+level was 0.51 mmol/L and her serum K+level 2.7 mmol/L with normal kidney function tests. She was already taking oral combined potassium citrate and potassium bicarbonate supplementation once a day before pregnancy. At the eighth gestational week, the medication was changed to an oral potassium color sachet of 1.5 gram per day until labor because of the insufficient dosage to maintain optimum potassium levels. She was also taking 365 milligrams of oral magnesium oxide twice a day before and during pregnancy. In the third trimester of the pregnancy, her serum Mg+level was 0.48 mmol/L and serum K+level 2.8 mmol/L. Because of the previous uterine surgery history, she underwent an elective cesarean operation at 39 weeks' gestation under spinal anesthesia and delivered a healthy 3090-gram female infant., Conclusion: Increased need for potassium and magnesium supplementation should be the critical considerations when managing pregnant patients with GS., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Objective: To introduce a new handmade device, the double Foley catheter (DFC), and compare it with the Foley catheter (FC) and Cook cervical ripening balloon for its effectiveness in labor induction., Methods: This prospective randomized controlled trial included 222 patients with unfavorable cervices. The patients were randomly allocated to the DFC, FC, and Cook cervical ripening balloon groups (n = 74 patients per group). The outcomes were evaluated using SPSS v. 23., Results: Bishop scores successfully increased with all three methods (P = 0.000 for all groups), and the rates of vaginal delivery within 24 and 48 h were similar (P = 0.101 and P = 0.390, respectively). The pain scores of the DFC and Cook cervical ripening balloon groups were similar, but were lower than those of the FC group (P = 0.011). The overall maternal satisfaction scores of the DFC and Cook cervical ripening balloon groups were not significantly different but were higher than those of the FC group (P = 0.014)., Conclusion: The maternal safety and success rate of labor induction were comparable between groups. However, the FC group had a higher pain score during catheter insertion and a lower maternal satisfaction rate. Moreover, considering the high cost of the Cook cervical ripening balloon, the DFC has an advantage, especially in low-resource countries., (© 2021 International Federation of Gynecology and Obstetrics.)

Background: The aim of this study was to determine the levels of lipid peroxidation (MDA) and antioxidants such as reduced glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) in the blood serum of patients with cirrhosis and liver transplantation., Methods: In this study, serum malondialdehyde acid (MDA) levels, superoxide dismutase (SOD), reduced glutathione (GSH), and catalase (CAT) activities were measured spectrophotometrically and compared to the results of the healthy control group., Results: SOD, CAT and GSH activities were significantly decreased in the patient groups compared to the healthy control group (p<0.05). MDA levels were significantly higher in the patient group compared to the healthy control group (p <0.05)., Conclusions: In conclusion, this study demonstrated that oxidative stress may play an important role in the development of liver cirrhosis and in liver transplantation. This study is the first one to show how MDA, SOD, CAT and GSH levels change in liver cirrhosis and liver transplantation, while further studies are essential to investigate antioxidant enzymes and oxidative stress status in patients with cirrhosis and liver transplantation., Competing Interests: Conflict of Interest: The authors stated that they have no conflicts of interest regarding the publication of this article., (2021 Mesut Aydin, Yaren Dirik, Canan Demir, Harun Egemen Tolunay, Halit Demir, published by CEON/CEES.)

Objective: Endocan is a novel marker of endothelial inflammation. In this study, we aimed to show whether there was a significant difference between the endocan levels of pregnant women with and without preterm premature rupture of membranes (PPROM and non-PPROM). Also, we aimed to find a relation between endocan levels and the latent period., Material and Methods: Pregnant women with PPROM between 28 and 34 weeks of gestation and those without PPROM with similar gestational weeks were included in the study. A total of 88 pregnant women, 44 with PROM and 44 healthy pregnancies, were evaluated. Demographic and obstetric features, leukocyte, and endocan levels of the study and control groups were compared., Results: The demographic features and obstetric history of both groups were similar. The mean leukocyte and endocan levels of the study group were higher than in the control group (p < 0.001 and 0.029, respectively). The leukocyte level was the only independent factor predicting PPROM after multivariate logistic regression analysis., Conclusion: Although the endocan levels were higher in patients with PPROM, multivariate analysis showed that the only independent predictive factor was the leukocyte level., (© 2021 Japan Society of Obstetrics and Gynecology.)

Aim : Zoonotic parasite infections affect many pregnant people around the world. Hydatid cystic disease is also a zoonotic disease caused by Echinococcus sp. This study aims to present the maternal-fetal results and clinical treatment of pregnant women diagnosed with liver hydatid cyst (CH). This zoonotic disease is discussed again in the light of current literature. Materials and Methods : Pregnant women with hydatid cyst monitored in a tertiary health center between 2018 and 2020 were evaluated. Seven cases were included in this study. We retrospectively collected and analyzed clinical data, which did not interfere with medical treatment. Results : Albendazole was started as medical therapy in six patients, and percutaneous drainage was applied to one patient. Three of our six patients who started medical treatment had to undergo surgery due to maternal complications that developed despite medical treatment. Two of our patients were delivered with a cesarean section due to the obstetric indications. Discussion : Hydatid cysts are most commonly caused by Echinococcus granulosus infection and most common in the liver. The diagnosis of liver hydatid cysts is not difficult, but pregnant women's treatment methods have some problems. Although both medical and surgical treatments are available, there is no consensus. We would also like to underscore that echinococcal disease of the liver should be kept in mind in the differential diagnosis of abdominal pain, jaundice, and/or fever, especially in endemic regions. We think that when we increase awareness about this disease, we can improve fetal and maternal outcomes by making an early diagnosis and management., (Copyright ©2021, Yale Journal of Biology and Medicine.)

Aim: We aimed to evaluate placental elasticity for the short-time prediction of delivery in cases of threatened preterm labor (TPL)., Methods: We performed a prospective study with consented pregnant women diagnosed with TPL (24th to 34th gestational week). According to the birth time, the patients were grouped into two groups, whether the delivery happened in the following first week or not. We compared the placental strain ratio (PSR) values between these two groups., Results: A total of 108 pregnant women divided into two groups according to the delivery time were enrolled in our study. The pregnant women who had a delivery in 1 week after hospitalization have increased PSR values when compared to those who have not delivered within 1 week (P < 0.001). Multivariate logistic regression analysis showed that cervical length and PSR were significantly associated with delivery in 1 week after hospitalization. When the cervical length was entered as a covariate (control) variable, PSR was significantly associated with delivery time (B = 0.504, odds ratio: 1.655, 95% confidence interval: 1.339-2.045, P < 0.001). A PSR value of 4.04 had a sensitivity of 77.78% and a specificity of 87.04% in terms of short-time prediction of the delivery time, in the receiver-operator curves analysis to determine the cut-off point PSR value., Conclusion: Elastography may contribute to predict the delivery time in high-risk pregnants with TPL., (© 2020 Japan Society of Obstetrics and Gynecology.)

Objective: To determine whether the ratio of the first-trimester aspartate aminotransferase (AST) to platelet ratio index (APRI) score will be useful as a new determinant of hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome that may develop in the later stages of pregnancy Study Design: Descriptive-analytical study., Place and Duration of Study: Perinatology Clinic of Etlik Zübeyde Hanım Maternity and Women's Health Teaching and Research Hospital, Ankara, Turkey. The data of patients diagnosed as having HELLP syndrome between 2018 and 2020 were analyzed retrospectively., Methodology: Forty-two pregnant women with HELLP syndrome as the study group and 74 pregnant women with no morbidities as the control group were included in the study. First-trimester APRI scores were compared for both the groups. A characteristic curve (ROC) analysis of the study was performed to determine the APRI score levels predicting HELLP syndrome., Results: One hundred and sixteen women with HELLP syndrome had significantly lower fibrinogen levels and platelet (PLT) levels than women without HELLP syndrome (p<0.001). Women with HELLP syndrome had significantly higher ALT, AST, creatinine, and INR levels. These differences were significantly different (p<0.001). Women who developed HELLP syndrome in the third trimester of pregnancy had significantly higher first-trimester APRI scores (0.64±0.10) than the control group (0.40±0.12, p<0.001). In the ROC analysis, 0.55 as a cut-off value for first-trimester APRI scores had a sensitivity of 88.1 % and a specificity of 94.6 % for predicting HELLP syndrome developing in the third trimester of pregnancy., Conclusion: There was an association of first-trimester APRI scores with the prediction of HELLP syndrome, possibly developing in the later weeks of pregnancy. Predicting HELLP syndrome in the early period can assist in proper management and taking necessary precautions. Key Words: HELLP syndrome prediction, First-trimester APRI, APRI scores in pregnancy, APRI score.

Objective: To evaluate the predictive value of the first-trimester aspartate aminotransferase (AST)/platelet count ratio [AST to platelet ratio index (APRI) score] for intrahepatic cholestasis in pregnancy (ICP)., Methods: This study consisted of a patient group diagnosed with ICP (n = 37) and a control group (n = 66) who presented to the hospital perinatology clinic between 2018 and 2020. Laboratory tests of both groups were analysed retrospectively. Age, gravida, parity, body mass index, third-trimester laboratory tests and first-trimester APRI scores were compared between the two groups. A receiver operating characteristic (ROC) analysis of the study was performed to determine the cut-off value for APRI score that is predictive of ICP., Results: Patients with ICP had significantly higher first-trimester APRI scores compared with controls (p < 0.001). In the ROC analysis, the cut-off value for APRI score was 0.57, with 86.5 % sensitivity and 77.3 % specificity. Spearman's correlation indicated that there was a significant positive association between first-trimester APRI score and third-trimester fasting bile acid level (r = 0.641, p < 0.001). The demographic characteristics of patients in the third trimester did not differ, except for AST and alanine transferase values., Conclusions: The APRI score calculated in the first trimester of pregnancy seems to be predictive of the development of ICP in the third trimester., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2020 Elsevier B.V.

Objectives : Limited data are available from recent trials involving pregnant women to guide Helicobacter pylori infection diagnosis. There are no data about the presence of H. pylori in the amniotic fluid as well. Furthermore, the relation between amniotic fluid H. pylori and hyperemesis gravidarum (HG) has not been characterized yet. Materials and Methods : This is a prospective study conducted after obtaining approval from the Ethics Committee. Pregnant women undergoing amniocentesis were enrolled in the study. The stool antigen test assessed the presence of H. pylori in amniotic fluid. A perinatologist independently performed an amniocentesis. The obtained amniotic liquid was sent to the laboratory to evaluate H. pylori infection by stool H. pylori antigen assay. We determined the rate of H. pylori in amniotic fluid and assessed relations between H. pylori infection and pregnancy outcome, including HG. Results : Between May and September 2017, we enrolled 48 pregnant women who underwent amniocentesis to detect possible fetal malformations. Patients were divided into two groups regarding the HG status. There were significant differences between the groups in terms of H. pylori infection presence. Among them, 28 (58.3%) were found to have a positive H. pylori test in their amniotic fluid. The rate of HG was significantly higher (71.4%) in patients who tested positive for H. pylori in amniocentesis than the H. pylori -negative group (20%), (p<0.001). Conclusions : The study's main new finding is that presence of H. pylori in the amniotic fluid is possible. Our data suggest that H. pylori -infected amniotic fluid is associated with the experience of past HG. The current study may have important implications for HG detection and help identify patients who would benefit from future preventive strategies., (Copyright ©2020, Yale Journal of Biology and Medicine.)

Objective: To compare the placental elasticity in fetuses with or without intrauterine growth restriction (IUGR)., Materials and Methods: One hundred pregnant women (50 IUGR and 50 healthy) with anteriorly located placenta were evaluated during the third trimester of pregnancy. Measurements were carried out by a machine that has a real-time elastographic ultrasonography feature. After obtaining the optimum image, three areas (subcutaneous tissue, center, and the edge of the placenta) were provided to identify the placental strain values. Then, the placental strain ratio (PSR) value was calculated automatically. Two groups compared in terms of their PSR values., Results: There was a significant difference in placental elasticity between the groups (P < 0.001). PSR value was 2.8 ± 1.2 in the IUGR group and 1.3 ± 0.6 in the control group. A PSR value of 1.78 had an 86% sensitivity (OR 4.3) and 80% specificity (OR 0.17) in IUGR cases. The positive predictive value was 81.1% and the negative predictive value was 85.1% for this cut-off value., Conclusions: We have shown that placental strain ratio is increased during the third trimester of pregnancy in fetuses with IUGR. Increased stiffness and elasticity may be responsible for the onset of IUGR in some cases.

Objective: The objective of this study is to compare the first-trimester hemogram parameters [neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR)] of pregnant women complicated by intrauterine growth retardation (IUGR) and normal pregnant women., Materials and Methods: We retrospectively evaluated the medical records of pregnant women (n=50) complicated with IUGR and pregnant women in the control group (n=50)., Results: The first-trimester NLR and PLR values of the pregnant women complicated by IUGR were 6.59±1.12 and 117.2±16.00, respectively. The first-trimester NLR and PLR values of the pregnant women in the control group were 2.84±0.55 and 112.80±13.01, respectively. There was a statistically significant difference between the two groups with respect to NLR (p<0.001)., Conclusion: Pregnancies complicated by IUGR have high neonatal mortality and morbidity rates. Therefore, the early diagnosis of disease and appropriate management are extremely crucial for both fetal and maternal prognoses. High NLR values in the first trimester may contribute to the early diagnosis of IUGR., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (©Copyright 2020 by Turkish Society of Obstetrics and Gynecology | Turkish Journal of Obstetrics and Gynecology published by Galenos Publishing House.)

Background We aimed to evaluate the efficiency of placental elasticity in predicting the amount of intraoperative bleeding via real-time tissue elastography technique. Methods Pregnant women in the third trimester of pregnancy who had planned delivery via cesarean section due to the recurrent cesareans were enrolled in the research (n = 78). Elastographic measurements of placental tissues of all cases were carried out by real-time elastographic ultrasonography. It is a tissue elastography software (Esaote MyLabSeven) that uses a 8-1-MHz multifrequency AC2541 Probe. Results A significant relationship was found between placental elasticity and intraoperative bleeding. There was a significant correlation between alterations in the preoperative and postoperative hemoglobin (Hb) and hematocrit (Hct) levels and placental strain ratio (SR) (P < 0.001, r: 0.831; P < 0.001, r: 0.733, respectively). Conclusion These findings may reflect an alteration at the tissue elasticity level. We hope that the use of real-time elastographic ultrasonography technique may give an idea about the amount of bleeding during the cesarean section.

Aim: The reproductive hormone levels and systemic physiology of women with hepatic cirrhosis are altered. Existing data have indicated the adverse effects of cirrhosis on both the mother and the fetus. Pregnancy is successful in most of the patients with chronic liver disease. But maternal and fetal complication rates are still high for decompensated hepatic cirrhosis. In this study, we aimed to evaluate the clinical features, etiological factors, medications, morbidity, mortality, and obstetric outcomes of pregnant women with hepatic cirrhosis., Methods: Pregnant women, who were diagnosed with maternal hepatic cirrhosis and followed up in our clinic between 2014 and 2017, were retrospectively evaluated. The pregnant women that had been followed up for hepatic cirrhosis were classified as compensated disease and decompensated disease. Eleven cases were included in this period., Results: The mean age of cases was 33.5 ± 5.5 years. The mean gravida number was 3.2 ± 1.1, and the mean parity number was 1.7 ± 1. Six cases were in the compensated cirrhosis stage, and 5 cases were in the decompensated cirrhosis stage. A pregnancy with decompensated cirrhosis was terminated after the fetal heart sound was negative in the 9th week of pregnancy. Spontaneous abortus occurred in one case (<20 weeks). The mean gestational week of the 9 cases was 33.3 ± 6.2. Two of the 9 cases delivered birth vaginally. Seven cases delivered by cesarean section. The mean first- and fifth-minute APGAR scores were 6.6 ± 1.41 and 8.2 ± 1.56, respectively. The mean birth weight was 2303 ± 981 g. Among 9 cases with live birth, 6 had compensated cirrhosis and 3 had decompensated cirrhosis. In the second trimester, upper gastrointestinal endoscopy was performed to all patients in terms of esophageal varices. Endoscopic band ligation was performed in 3 cases with upper gastrointestinal bleeding. The postpartum mortality did not occur. Discussion . Pregnancy is not recommended for patients with hepatic cirrhosis due to high maternal and fetal morbidity and mortality. The pregnancy course of cases with cirrhosis changes according to the stage of liver injury and severity of disease. Although the delivery method is controversial, delivery by cesarean section is recommended for patients with esophageal varices by the reason of bleeding from varices after pushing during labor. The bleeding risk must be kept in mind as coagulopathy is common in hepatic diseases. The maternal-fetal morbidity and mortality rates have been decreased by the current developments in hepatology, prevention of bleeding from varices with drugs and/or band ligation, improvement in liver transplantation, and increasing experience in this issue., Competing Interests: The authors declare that they have no conflict of interest., (Copyright © 2020 Harun Egemen Tolunay et al.)

Objective: In this study, we aimed to evaluate the elasticities of fetal placentas with a single umbilical artery using the Virtual Touch Tissue Quantification (VTTQ) technique., Materials and Methods: Pregnant women with fetuses with a single umbilical artery (SUA) and pregnant women with fetuses having three vessel cord (3VC) at 18-22 weeks of gestation were enrolled in the research. The placentas were evaluated and divided into three equal parts as the inner 1/3 of the placenta (fetal edge), the outer 1/3 of the placenta (maternal edge) and the central 1/3 of the placenta (central part). Shear-wave velocity (SWV) measurements were used in the elastographic evaluation of placentas by VTTQ., Results: Forty pregnant women were included in the study (n = 20 SUA, n = 20 three vessel cord pregnant women). The placental Acoustic Radiation Force Impulse (VTTQ) of the placenta regarding SWV measurement values of the fetal edge of the placenta in the fetuses with SUA and the control group were 0.876 and 0.957 m/sec, respectively. A significant statistical difference was found between the groups regarding the measurement of the stiffness of fetal placenta (p = 0.021). There was no significant difference between the measured stiffness values of the central or outer region of the placentas., Conclusions: In this study, we found lower SWV scores for the fetal edge of the placenta with SUA. This finding may reflect tissue elasticity level, and we hope that the use of the VTTQ technique may contribute to predicting the pregnancy-related morbidities of fetuses with SUA in the future.

We aimed to evaluate the efficiency of placental elasticity in predicting a placental invasion anomaly with the Virtual Touch Quantification (VTQ) technique. Pregnant women in the third trimester with suspected placental invasion anomaly were enrolled into the research (n = 58). The placenta was evaluated and divided into three equal parts as foetal edge (inner 1/3 of placenta), maternal edge (outer 1/3 of placenta) and the central part (central 1/3 of placenta). Shear wave velocity (SWV) measurements were used in the elastographic evaluation of placentas by VTQ. We performed the measurements at the different regions of placenta for sampling the variety areas of the placenta. Acoustic Radiation Force Impulse (ARFI) Elastography scores were significantly higher in the group in which an invasion was detected during the surgery of patients with preoperative placental invasion suspicion. A significant difference in the measurements of the inner, central and outer third of the placenta between the groups was found (p < .001). In this study, we have shown higher SWV scores of placental measurements of the patients with preoperative suspected anomalies and an invasion detected during their surgery. These findings may reflect an event at the tissue elasticity level and we hope that the use of the VTQ technique may contribute to an early prediction of placental invasions before surgery in the future via new research. Impact statement What is already known on this subject? Placenta invasion anomalies (PIA's) are characterized by haemorrhages which can threat the mother's life. Placental invasion anomalies are among the most important causes of maternal mortality and morbidity. Early diagnosis is very important condition in reducing the mortality and morbidity. Gray scale ultrasonography (US) is mostly used in early diagnosis of PIA's. Acoustic radiation force impulse elastography (ARFI) is a new elastographic ultrasonography technic. We aimed to evaluate a new method in the early diagnosis of PIA's using ARFI technique. There is no study in the diagnosis of PIA's by ARFI in the literature to our knowledge. We think that this original study will contribute to the literature. What do the results of this study add? We showed the accuracy of ARFI in determination of PIA's. ARFI scores were significantly higher in the group in which invasion was detected during surgery of patients with preoperative placental invasion suspicion. What are the implications are of these findings for clinical practice and/or further research? Our findings may reflect an event at the tissue elasticity level and we hope that the use of VTQ technique may contribute to early predict of placental invasions before surgery in the future via new researches. Early diagnosis of placental invasion anomalies may reduce mortality and morbidity.

Objective This study aimed to evaluate the oxidant-antioxidant status of amniotic fluid in pregnant women with foetal congenital malformations of the central nervous system. Methods We studied pregnant women with foetal congenital nervous system anomalies at 16-22 weeks' gestation (n = 36). The control group (n = 30) consisted of pregnant women at the same gestational age who underwent amniocentesis, resulting in a normal karyotype. We analysed glutathione, catalase, and malondialdehyde levels in amniotic fluid. Enzyme activation was measured by spectrophotometry. Results The demographic features of the groups were similar in terms of age, parity, body mass index, and gestational weeks. We detected lower glutathione and catalase levels in the foetal congenital anomaly group than in the control group. We detected higher malondialdehyde levels in the foetal congenital anomaly group than in the control group. Conclusion In the organism, the rate of formation of free radicals and their rate of removal are balanced, and this is called oxidative balance. As long as oxidative stability is achieved, the organism is not affected by free radicals. This fact should be kept in mind to avoid any type of teratogenic agent that could lead to congenital disorders.

Aim: To evaluate the efficacy and safety of levonorgestrel-releasing intrauterine system (LNG-IUS) in the long-term treatment of heavy menstrual blood loss in women unrelated to intrauterine pathology., Methods: One hundred and six parous women aged 33-48 years with recurrent heavy menstrual bleeding (HMB) participated in this study. The women were followed up for 24 months and were assessed for intensity of bleeding both for pre- and post-insertion periods. An LNG-IUS was inserted in each patient within 7 days of the start of menstrual flow. The women were followed up at 1, 3, 6, 12, 18, and 24 months following the insertion of the intrauterine device., Results: One hundred and two women completed the follow-up period and had a significant reduction in the amount of menstrual blood loss. The LNG-IUS was well tolerated by all women. Pre-treatment of the use of the LNG-IUS, endometrial biopsy patterns for irregular proliferative endometrium and for atypical simple hyperplasia were 34/106 (32.08%) and 61/106 (57.55%) respectively and after treatment no abnormal pathologic findings were determined (p < 0.001)., Conclusion: Our findings indicate that the LNG-IUS is effective for significantly reducing the amount of menstrual blood loss in women with HMB., (© 2017 S.

The present study was initiated because of concerns expressed by NHLBI-funded mid-career investigators regarding perceived difficulties in the renewal of their grant awards. This led us to ask: "Are mid-career investigators experiencing disproportionate difficulties in the advancement of their professional careers?" Our portfolio analysis indicates that there has been a significant and evolving shift in the demographics of research project grant (RPG) awardees at NHLBI. In 1998, mid-career (ages 41-55) investigators constituted approximately 60% of all investigators with the remaining 40% being equally divided between early-stage (ages 24-40) investigators and established (ages 56 to 70 and older) investigators. However, since 1998, the proportion of established RPG awardees has been increasing in a slowly progressive and strikingly linear fashion. At the same time the proportion of early-stage awardees fell precipitously until 2006 and then stabilized. During the same period, the proportion of mid-career awardees, which had been relatively stable through 2006, began to fall significantly. In examining potential causes of these demographic shifts we have identified certain inherent properties within the RPG award system that appear to promote an increasingly more established awardee population and a persistent decrease in the proportion of mid-career investigators. A collateral result of these demographic shifts, when combined with level or declining funding, is a significant reduction in the number of RPG awards received by NHLBI mid-career investigators and a corresponding decrease in the number of independent research laboratories., Competing Interests: The authors have declared that no competing interests exist.

Objective: To evaluate the physiologic changes in intraocular pressure associated with pregnancy in healthy Syrian refugee women in Turkey., Materials and Methods: In this cross-sectional study, intraocular pressures were measured using a Goldmann tonometer in 235 patients in the first, second, and third trimester of pregnancy and puerperium among Syrian refugees in Turkey., Results: Mean intraocular pressures values of the right eye were 15.5±2.5 mmHg, 14.4±1.4 mmHg, 13.9±1.6 and 14.7±1.9 mmHg in the three trimesters and puerperium, respectively. Mean intraocular pressures values of the left eye were 15.3±1.6 mmHg, 14.3±1.4 mmHg, 13.9±1.6 and 15.3±2.2 mmHg in the three trimesters and puerperium, respectively. The mean intraocular pressures values measured from both eyes were significantly higher in first trimester and puerperal period than in the third trimester (p<0.001)., Conclusion: Changes in the intraocular pressure in pregnancy are common and temporary. This study shows the baseline changes in the intraocular pressure during pregnancy in healthy women. Therefore, we cannot extrapolate the results to the whole eye. A decrease in intraocular pressures was shown in healthy pregnant women., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Objectives: To assess the effects of heavy metal and trace element concentrations in blood and follicular fluid on assisted reproductive technology cycle outcome., Study Design: A prospective study was conducted between January 2012 and July 2012 in a university hospital infertility clinic. One hundred and one patients with unexplained infertility who underwent intracytoplasmic sperm injection using GnRH-antagonist protocol were recruited. Concentrations of four toxic metals (Cd, Pb, Hg, As) and three trace elements (Cu, Zn, Fe) were measured both in blood and follicular fluid specimens. Patients were evaluated in two groups; the study group consisted of patients with ongoing pregnancy (n=20) and the reference group consisted of patients experienced assisted reproductive technology failure, miscarriage or biochemical pregnancy (n=81)., Results: Demographics and cycle parameters were comparable between the groups except for median number of day 3 Grade A embryos. Statistically significant negative correlations were found between blood Pb levels and number of MII oocytes, implantation, clinical pregnancy and ongoing pregnancy rates. Results of the log binomial regression revealed 2.2% lower risk for ongoing pregnancy for each 1μg/dL higher blood Pb concentration while holding the other variables in the model constant (RR 0.978; 95% CI 0.956-0.998; P=.041). Also, the results revealed 71.9% lower risk for ongoing pregnancy for each 1μg/dL higher follicular fluid Cu concentration while holding the other variables in the model constant (RR 0.288; 95% CI 0.085-0.92; P=.039)., Conclusion: Blood concentrations of Pb and follicular fluid concentrations of Cu seem to have significant impacts on assisted reproductive technology cycle outcome., (Copyright © 2016 Elsevier Ireland Ltd.

Purpose: To compare the effects of combined oral contraceptives (OCs) containing cyproterone acetate and drospirenone in the treatment of polycystic ovary syndrome (PCOS)., Methods: Fifty-two patients with PCOS were randomized in two groups: group A (n = 26) received 0.035 mg ethinyl estradiol + 2 mg cyproterone acetate and group B (n = 26) received 0.03 mg ethinyl estradiol + 3 mg drospirenone-containing OCs for 12 months. Baseline clinical features including body mass index, waist to hip ratio (WHR), and modified Ferriman-Gallwey (mFG) score were noted. Baseline biochemical parameters included androgen profile, carbohydrate metabolism, lipid profile, and oxidative stress. The percentages of changes for all parameters were compared., Results: The groups were comparable regarding the baseline characteristics. WHR decreased significantly from baseline (-4 % [-31 to 35]) in group B when compared to group A (0 % [-11 to 14]) (P = 0.033). The total mFG score decreased significantly from baseline (-35 % [-71 to 10]) in group A when compared to group B (-18 % [-72 to 30]) (P = 0.035). Changes in androgen hormone profile were comparable except DHEA-SO4 (-32 % [-53 to 15] in group B vs. -10 % [-49 to 63] in group A; P = 0.046). The effects of the drugs were similar regarding carbohydrate metabolism, lipid profile, and oxidative stress parameters., Conclusions: Cyproterone acetate containing OCs seem to be more effective to treat clinical hirsutism in patients with PCOS after 12 months of treatment.

Background and Aim of the Study: The long-term outcomes of aortic valve-sparing (AVS) root replacement in Marfan syndrome (MFS) patients remain uncertain. The study aim was to determine the utilization and outcomes of AVS root replacement in MFS patients enrolled in the Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC)., Methods: At the time of this analysis, 788 patients with MFS were enrolled in the GenTAC Registry, of whom 288 had undergone aortic root replacement. Patients who had undergone AVS procedures were compared to those who had undergone aortic valve replacement (AVR)., Results: AVS root replacement was performed in 43.5% of MFS patients, and the frequency of AVS was increased over the past five years. AVS patients were younger at the time of surgery (31.0 versus 36.3 years, p = 0.006) and more likely to have had elective rather than emergency surgery compared to AVR patients, in whom aortic valve dysfunction and aortic dissection was the more likely primary indication for surgery. After a mean follow up of 6.2 +/- 3.6 years, none of the 87 AVS patients had required reoperation; in contrast, after a mean follow up of 10.5 +/- 7.6 years, 11.5% of AVR patients required aortic root reoperation. Aortic valve function has been durable, with 95.8% of AVS patients having aortic insufficiency that was graded as mild or less., Conclusion: AVS root replacement is performed commonly among the MFS population, and the durability of the aortic repair and aortic valve function have been excellent to date. These results justify a continued use of the procedure in an elective setting. The GenTAC Registry will be a useful resource to assess the long-term durability of AVS root replacement in the future.

Previous data suggest women are at increased risk of death from aortic dissection. Therefore, we analyzed data from the GenTAC registry, the NIH-sponsored program that collects information about individuals with genetically triggered thoracic aortic aneurysms and cardiovascular conditions. We performed cross-sectional analyses in adults with Marfan syndrome (MFS), familial thoracic aortic aneurysm or dissection (FTAAD), bicuspid aortic valve (BAV) with thoracic aortic aneurysm or dissection, and subjects under 50 years of age with thoracic aortic aneurysm or dissection (TAAD <50 years). Women comprised 32% of 1,449 subjects and were 21% of subjects with BAV, 34% with FTAAD, 22% with TAAD <50 years, and 47% with MFS. Thoracic aortic dissections occurred with equal gender frequency yet women with BAV had more extensive dissections. Aortic size was smaller in women but was similar after controlling for BSA. Age at operation for aortic valve dysfunction, aneurysm or dissection did not differ by gender. Multivariate analysis (adjusting for age, BSA, hypertension, study site, diabetes, and subgroup diagnoses) showed that women had fewer total aortic surgeries (OR = 0.65, P < 0.01) and were less likely to receive angiotensin converting enzyme inhibitors (ACEi; OR = 0.68, P < 0.05). As in BAV, other genetically triggered aortic diseases such as FTAAD and TAAD <50 are more common in males. In women, decreased prevalence of aortic operations and less treatment with ACEi may be due to their smaller absolute aortic diameters. Longitudinal studies are needed to determine if women are at higher risk for adverse events., (Copyright © 2013 Wiley Periodicals, Inc.)

Objective: To demonstrate a unique case report about late and isolated vulvar metastasis of sigmoid adeno-carcinoma with review of the literature., Material-Method: 57 year old postmenopausal patient with prior sigmoid colon cancer history was admitted with isolated vulvar mass. Immunohistochemistry (IHC) and KRAS gen mutation analysis following surgery were performed to discriminate the metastasis from a vulvar primary malignancy. Further imaging techniques were also performed to exclude additional tumours., Results: Immunohistochemistry (IHC) and KRAS gene mutation analysis revealed isolated metastasis of the colonic adeno-carcinoma in the vulva., Conclusion: Isolated and late occurring vulvar metastasis of colonic origin is very unusual. Careful evaluation and IHC is useful for such cases.

Background: Genetically triggered thoracic aortic conditions (GenTACs) represent an important problem for patients and their families. Accordingly, the National Heart, Lung, and Blood Institute established the first phase of its national GenTAC Registry in 2006., Enrollment and Diagnoses: Between 2007 and 2010, 6 enrolling centers established the GenTAC I Registry consisting of 2,046 patients (Marfan syndrome 576 [28.2%], bicuspid aortic valve disease 504 [24.6%], aneurysm or dissection age <50 years 369 [18%], and others). Biologic samples for DNA analyses (white blood cells or saliva) are available in 97%, and stored plasma is available in 60% of enrollees., Results: Initial scientific inquiry using the GenTAC Registry has included validation studies of genetic causes for aortic syndromes, potential usefulness of transforming growth factor beta (TGFB) blood levels in Marfan subjects, and current surgical approaches to ascending aortic conditions., Future Opportunity: The second phase of GenTAC will allow biannual follow-up of GenTAC I enrollees for up to 9 years, enrollment of an additional 1,500 subjects, further integration of imaging findings with clinical and genetic data through utilization of an imaging core laboratory, important validation of phenotype-genotype correlations through a phenotyping core laboratory, and integration of a scientific advisory committee to help define the full range and depth of the Registry's scientific capabilities. The registry resources are available to the external scientific community through an application process accessible at https://gentac.rti.org., (Copyright © 2011 Mosby, Inc. All rights reserved.)

Background: Genetic disorders are an important cause of thoracic aortic aneurysms (TAAs) in young patients. Despite advances in the treatment of genetically triggered TAAs, the optimal syndrome-specific treatment approach remains undefined. We used data from the National Institutes of Health-funded, multicenter National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) to characterize the contemporary surgical treatment of patients with genetically triggered TAAs., Methods: GenTAC's aim is to collect longitudinal clinical data and banked biospecimens from 2800 patients with genetically triggered TAAs. We analyzed data from the 606 patients (mean age, 37.5 years) enrolled in GenTAC to date whose clinical data were available., Results: The patients' primary diagnoses included Marfan syndrome (35.8%), bicuspid aortic valve with aneurysm (29.2%), and familial TAAs and dissections (10.7%). Of these, 56.4% had undergone at least one operation; the most common indications were aneurysm (85.7%), valve dysfunction (65.8%), and dissection (25.4%). Surgical procedures included replacement of the aortic root (50.6%), ascending aorta (64.8%), aortic arch (27.9%), and descending or thoracoabdominal aorta (12.4%). Syndrome-specific differences in age, indications for operation, and procedure type were identified., Conclusions: Patients with genetically transmitted TAAs evaluated in tertiary care centers frequently undergo surgical repair. Aneurysm repairs most commonly involve the aortic root and ascending aorta; distal repairs are less common. Like TAAs themselves, complications of TAAs, including dissection and aortic valve dysfunction, are important indications for intervention. Future studies will focus on syndrome- and gene-specific phenotypes, biomarkers, treatments, and outcomes to improve the treatment of patients with TAAs.

Mouse erythroleukemia (MEL) cells provide a useful model system to examine the regulation of globin gene expression. MEL cells ordinarily do not express globin genes, but in the presence of inducers, such as dimethyl sulfoxide or hexamethylene bisacetamide, they mimic erythroid differentiation. We have developed a cell-free transcription system from uninduced MEL cells to determine the requirements for mRNA synthesis. The MEL system directs accurate transcription of adenovirus type 2 major late DNA and mouse betamaj-globin with an efficiency comparable to those of HeLa and KB cell extracts. Using the procedure of Matsui et al. (T. Matsui, J. Segall, P.A. Weil, and R.G. Roeder, J. Biol. Chem. 255:11992-11996, 1980), we have isolated three active fractions from both MEL and HeLa cell extracts which are required for accurate transcription and have shown that equivalent fractions from MEL and HeLa cell extracts are interchangeable. Our findings suggest that the components required for initiation of transcription are similar in different cell types, at least to the extent that they can be assayed in these in vitro systems.

Distinct RNA polymerase II transcription preinitiation, initiation, and elongation complexes can be formed in vitro on cloned adenovirus 2 DNA sequences containing the major late promoter. These transcription complexes are stable and can be rapidly isolated by gel filtration of HeLa whole cell extracts. In the absence of exogenous nucleotides and under appropriate salt conditions, a stable but transcriptionally incomplete preinitiation complex is formed. When this complex is incubated in the presence of adenosine or deoxyadenosine triphosphates, the beta-gamma phosphodiester bond is hydrolyzed, and RNA polymerase II joins the complex, thereby converting it into a stable initiation complex capable of forming (but prior to the formation of) the first phosphodiester bond. When this complex is isolated and incubated in the presence of all four nucleoside triphosphates, it is converted into an elongation complex that then permits the synthesis of phosphodiester bonds and the correct run-off transcript. A limiting transcription component is sequestered in the preinitiation complex. This factor is released upon elongation and can reassociate with new DNA templates during subsequent rounds of initiation. Therefore, class II genes do not appear to form activated transcription units stable for multiple rounds of transcription; rather, their transcriptional activity may be controlled in part by regulating the association of transcription factors at each initiation event.

Left ventricular hypertrophy or treatment with dexamethasone caused a 2.5-fold to threefold increase in both immunoreactive atriopeptin (AP) and AP messenger RNA (mRNA), primarily in left ventricular tissue. The combined treatments increased immunoreactive AP and AP mRNA more than either treatment alone. In the animals in which cardiac hypertrophy had been produced by abdominal aortic constriction, there was a decrease in atrial levels of AP and an increase in plasma levels of immunoreactive AP. The increase in left ventricular immunoreactive AP was confirmed by immunohistochemical staining of tissue from hypertrophied and/or dexamethasone-treated rats. The mRNA accumulated in the left ventricle was identical to atrial AP mRNA, as judged by transcriptional start site and by size on Northern blots. Because the mass of ventricular tissue is substantially greater than that of atrial tissue, the induced mRNA levels may represent a total abundance approaching one third of the total AP mRNA in the atria. High performance liquid chromatographic purification of ventricular extracts primarily demonstrated the presence of the high molecular precursor and small amounts of C-terminal peptide AP. Induction of ventricular AP (mRNA and peptide) may represent regression of the tissue to an earlier developmental form. These data provide a unique example of regulation of AP biosynthesis in nonatrial tissue.

A two-step procedure has been developed for the formation of RNA polymerase II transcription initiation and elongation complexes. Initiation complexes are rapidly formed in HeLa cell-free extract supplemented with a DNA template containing the adenovirus 2 major late promoter and ATP. Assembly of transcription components required for correct initiation is absolutely dependent on specific eukaryotic promoter sequences. Sarkosyl-sensitive transcription initiation complexes are rapidly converted to Sarkosyl-resistant elongation complexes when supplemented with the remaining nucleoside triphosphates. The 60S initiation complex can be extensively purified by glycerol gradient centrifugation and is easily separated from free RNA polymerase II and free DNA template. Recovery of this stable complex is greater than 90%. Specific transcription cannot be detected if the DNA template is subsequently added to gradient fractions containing HeLa cell-free extract components alone. This suggests that the DNA templates promote the specific assembly of RNA polymerase II and transcription factors required for accurate initiation. Since conversion of purified initiation complexes to elongation complexes can occur without additional HeLa cell components, the presence of transcription components required for initiation and elongation in a single complex is indicated.
