Obstetrics and perinatal outcomes between elective single versus double blastocyst transfer in women younger than 35 years: A cross-sectional study.

INTRODUCTION: Clinicians have a positive attitude towards multiple embryo transfer in in vitro fertilization (IVF) cycles, considering increased live birth rates compared to single embryo transfer. We aimed to evaluate obstetric and perinatal outcomes among young women who became clinically pregnant after single & double blastocyst transfer. MATERIAL-METHOD: 545 women under 35 years who became clinically pregnant after fresh blastocyst transfer was evaluated retrospectively. The participants were divided1according to the transferred embryo number - the elective single blastocyst transfer group (eSBT) (n=112) and the double blastocyst transfer group (DBT group) (n=433). Obstetric and perinatal outcomes were recorded. RESULTS: Live birth and abortion rates per pregnancy and per gestational sac, having a fetus with congenital anomaly per pregnancy and per neonate, and gestational complications were comparable between the groups. Multiple pregnancy, Cesarean section, and admission to neonatal intensive care unit (NICU) and hospitalization day in NICU per neonate were higher in the DBT group than in the eSBT group. Mean gestational week, birth weight, birth height decreased with the embryo transfer number. CONCLUSION: DBT transfer appears to be associated with increased multiple pregnancies, Cesarean section, prematurity, decreased fetal anthropometric measurements, and admission to NICU without an increase in live birth and abortion rates. Therefore, it will be easier for clinicians to choose eSBT by providing young couples undergoing IVF treatment with detailed information about multiple pregnancies and prematurity.

Intracytoplasmic sperm injection cycle success in patients under 35 years old with diminished ovarian reserve plus severe male factor.

OBJECTIVE: We aimed to evaluate intracytoplasmic sperm injection (ICSI) outcomes in young patients with diminished ovarian reserve (DOR) plus severe male factor (SMF) compared with age-matched controls with DOR. STUDY DESIGN: A total of 189 infertile women under 35 years with DOR undergoing ICSI procedures were included retrospectively. Participants whose partners' sperm analysis was normal considered as the DOR group (n = 154) and whose partners' had SMF considered as the DOR + SMF group (n = 35). The two groups were compared regarding cycle characteristics and pregnancy outcomes. RESULTS: Demographic features except infertility duration were similar between two groups. The duration of infertility was significantly longer in the DOR + SMF group compared to the DOR group (p = 0.02). Ovarian stimulation characteristics, oocyte retrieval parameters, fertilization rate, quality of embryos, embryo cancellation rate, and development up to blastocyst stage were found similar between two groups. Implantation, clinical pregnancy, abortion, and live birth rate, multiple pregnancy rate per cycle were distributed homogenously between the DOR and DOR + SMF groups. Regarding perinatal and neonatal outcomes of groups, fetal height and weight were significantly lower in DOR + SMF group than in DOR group (p = 0.001 and 0.01, respectively). Gestational week at delivery was lower in the DOR + SMF group compared to the DOR group (p < 0.0001). CONCLUSION: Fetal anthropometric measures were lower regarding to preterm delivery in the DOR + SMF group than the DOR group. Large sample-sized studies should be performed to explain the decreased gestational week at the time of delivery in the DOR + SMF group.

The association between gestational diabetes mellitus and DNA damage in umbilical cord leukocytes and placental samples.

Objective(s): To evaluate the relation between gestational diabetes mellitus (GDM) and maternal and/or fetal DNA integrity. Method: 59 pregnant women were classified into two groups on the basis of 75 g oral glucose tolerance test (OGTT) and glycemic profile (GP): Control group (OGTT and GP normal, n = 29) and GDM group (abnormal 75 g OGTT, n = 30). The umbilical cord blood and placental samples obtained from the maternal side were collected at the time of delivery. Alkaline comet assay was performed for the determination of DNA damage. The trial was approved with the protocol number 72867572.050.01.04-299082. Result(s): Body mass index (BMI), weight gain during pregnancy, glycemic means and fetal weight were increased in GDM group compared control group (p = .01, .0001, .04, and .01, respectively). In the GDM group, the number of large-for-gestational-age (LGA) infants was significantly higher compared to the nondiabetic group (p = .04). Tail DNA percentages in placental samples were higher in the GDM group compared to controls (p = .01); however, DNA integrity in umbilical cord leukocytes was similar between the groups (p = 0.1). In contrast to umbilical cord DNA damage, placental DNA damage showed positive correlation with maternal glycemia in the whole group and within each group. The positive association of placental DNA damage and GDM remained after adjusting for age, BMI, smoking, glycemia, gestational age at delivery, fetal weight at delivery, and delivery type (p = .01). Conclusion(s): Placental DNA damage is associated with GDM and placental cells seem to be more vulnerable to DNA damage compared to fetal blood cells.

The association between preterm delivery and postpartum bleeding in otherwise uncomplicated pregnancies

Objective: The primary aim was to investigate whether preterm delivery was an independent risk factor for blood or blood products transfusion in the intrapartum or postpartum period, considered as a proxy for severe obstetric bleeding. Material and Methods: Throughout a 9-month-period, 216 uncomplicated singleton deliveries were included in a cross-sectional study after exclusion of severe maternal and fetal morbidity, such as chorioamnionitis, and use of medications including tocolytics. Maternal and neonatal data were evaluated and compared across preterm (between 24 0/7-36 6/7 weeks' gestation) and term (between 37 0/7-41 6/7 weeks' gestation) deliveries. Primary and secondary outcomes were requirement for blood or blood products transfusion until discharge and change in hemoglobin value and hematocrit from baseline to postpartum hour 6, respectively. Logistic regression models were constructed to evaluate the effect of preterm delivery on the primary outcome. Results: There were 90 (41.7%) preterm deliveries with an overall cesarean section rate of 77.8%. Preterm delivery was not an independent risk factor for the primary outcome, when route of delivery, maternal body-mass index, antenatal steroid administration, and baseline (admission) platelet and leukocyte counts were controlled for [adjusted risk ratio, 2.46; 95% confidence interval (CI), 0.69-8.77; p=0.16]. Subgroup analysis, including cesarean deliveries, revealed a similar result (adjusted risk ratio, 1.65; 95% CI, 0.42-6.48; p=0.47). Secondary outcomes, including decrease in mean or percent values of hemoglobin and hematocrit measurements, were also similar across preterm and term groups, both after vaginal and cesarean delivery (for all comparisons, p>0.05). Conclusion: Preterm delivery is not independently associated with increased requirement for blood transfusions or decreased hemoglobin and hematocrit values following otherwise uncomplicated vaginal or cesarean delivery of singletons.

The association between age-related infertility and deoxyribonucleic acid (DNA) integrity parameters of granulosa cells and lymphocytes.

This study aimed to investigate the association between deoxyribonucleic acid (DNA) integrity parameters and advanced maternal age (AMA)-related infertility. The granulosa cells and the lymphocytes obtained from 119 infertile women were recruited. Patients were divided into two groups: the AMA group (≥35 years, n = 26) and the non-AMA group (<35 years, n = 93). The tail length, tail moment and tail DNA percentage were evaluated as the DNA integrity parameters using comet assay. Infertility duration (p=.001), luteinising hormone (p=.01) and progesterone levels (p<.0001) were higher and smoking was more prevalent in the AMA group (p=.001). AMA group was stimulated with higher gonadotropin doses (p=.04) and had decreased anti-mullerian hormone levels (p<.0001). All of DNA integrity parameters were distributed homogenously between the groups; however, the tail length of lymphocytes was higher (p=.02) in the AMA group. Fertilisation was lower (p=.02), oocyte quality was tended to be poor (p=.03) and blastocyst transfer was lower in the AMA group (p=.03). Embryo quality was distributed homogenously between the groups. Implantation, clinical pregnancy and live birth rates were similar between the groups. Impact StatementWhat is already known on this subject? Advanced maternal age (AMA)-related infertility is associated with diminished ovarian reserve and alteration in follicular environment resulting in poor oocyte quality; however, the exact pathophysiologic mechanism is not clear.What do the results of this study add? Tail length, tail deoxyribonucleic acid (DNA) percentage, tail moment of granulosa cells were nonsignificantly higher in the AMA group compared to younger patients. All of the DNA integrity parameters of lymphocytes were nonsignificantly higher; however, only tail length of lymphocytes was statistically higher in the AMA group than the non-AMA group. A positive correlation was observed between DNA integrity parameters of lymphocytes and body mass index. There were no correlations between DNA integrity parameters of granulosa cells and lymphocyte and infertility duration, gonadotropin dose, duration of ovarian stimulation, oocyte score, embryo score, basal hormone levels and anti-mullerian hormone levels.What are the implications of these findings for clinical practice and/or further research? Our findings offer new insight for further understanding the role of granulosa cells in mediating the poor reproductive outcome of ageing patients. Understanding the mechanisms of ovarian ageing and poor oocyte quality in women with AMA may help to identify specific targets for improving oocyte quality with ageing.

The role of oxidant status on the etiopathogenesis of unexplained infertility and intracytoplasmic sperm injection - embryo transfer success: a case-control study.

The present study aims to evaluate the role of follicular fluid (FF) and serum (s) total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) on the etiopathogenesis of unexplained infertility (UI) and intracytoplasmic sperm injection-embryo transfer (ICSI-ET) success. Twenty UI patients and 20 controls with male factor undergoing an ICSI-ET cycle were recruited. FF samples aspirated from mature follicles and blood samples collected just before the oocyte retrieval were stored until analysis. Embriyo quality and implantation, clinical pregnancy and living birth rates were evaluated.FF-TOS and FF-OSI of the UI patients were higher than the control group. s-TOS and s-OSI were significantly increased in the UI group compared to the control group. However, only s-TOS was positively associated with UI diagnosis after age-adjustment. FF-OSI was negatively associated with embryo quality in the UI group (but not in the whole group) after age-adjustment. No significant effect of TAS, TOS, and OSI on implantation, clinical pregnancy and live birth rate was observed. In conclusion, especially s-TOS can have a partial role in the etiopathogenesis of UI. High FF-OSI can decrease the quality of embryo in patients with UI.Impact statementWhat is already known? Total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI), which is the ratio of TOS to TAS, provide a broad overview of redox status.What do the results of this study add? An elevated serum TOS (s-TOS) was associated with UI after age-adjustment. Follicular fluid OSI (FF-OSI) was negatively associated with embryo quality and embryo score in the UI group (but not in the whole group) after age-adjustment. No significant effect of TAS, TOS, and OSI was observed on implantation, clinical pregnancy, and live birth rate.What are the implications of these findings for clinical practice and/or further research? Evaluation of FF-OSI in women with unexplained infertility can be considered to predict embryo quality. Further studies that evaluate antioxidant agents to decrease oxidative stress in UI and its' clinical implications are warranted.

Maternal serum procalcitonin levels in prediction of chorioamnionitis in women with preterm premature rupture of membranes.

INTRODUCTION: Chorioamnionitis is one of the most important maternal complications in the expectant management of patients with preterm premature rupture of membranes (PPROM). Procalcitonin (proCT), the precursor of the hormone calcitonin, is used to differentiate bacterial infections from non-bacterial ones. The objective of the study was to determine the efficacy of maternal serum procalcitonin levels in the early prediction of chorioamnionitis in women with PPROM. MATERIAL AND METHODS: The study was conducted in 76 pregnant women hospitalized due to PPROM at the maternal-fetal medicine unit of a tertiary center in Istanbul. Patients were followed up with white blood cell (WBC), C-reactive protein (CRP) and proCT levels every 2 days. The values of investigated parameters were recorded at the diagnosis of PPROM and at the time of delivery. The maximum values during the follow-up period were also recorded. RESULTS: Out of the 76 patients with PPROM, 15 (19.73%) developed clinical chorioamnionitis. No significant difference could be detected in the gravidity, parity, duration of hospitalization and gestational week at diagnosis between those patients who developed clinical chorioamnionitis and those who did not. The WBC at the time of hospital admittance and before delivery, and CRP levels before delivery were statistically higher in the chorioamnionitis group (p < 0.05). No difference in the proCT levels could be detected either at the time of hospital admittance or before delivery between the two groups. CONCLUSIONS: Maternal proCT was not found to be predictive of chorioamnionitis. However, since there are reports in the literature that contradict these results, further studies are warranted to determine the true efficacy of proCT in the prediction of clinical chorioamnionitis.

DNA methylation profiles of genes associated with angiogenesis in the samples of placenta in pregnancies complicated by intrauterine growth restriction.

BACKGROUND: Impairment in placental angiogenesis is blamed for the etiopathogenesis of intrauterine growth restriction (IUGR). AIM: To assess the genes related to angiogenesis in placental biopsies of pregnancies complicated by IUGR that could be aberrantly methylated and adversely affect placental angiogenesis. METHODS: The methylation profiles of soluble fms-like tyrosine kinase-1 (sFLT-1), vascular endothelial growth factor (VEGF), and the placental growth factor (PIGF) were evaluated using Illumina MiSeq™ System in placental biopsies from term IUGR pregnancies without preeclampsia (n = 18) and healthy controls (n = 17). DNA was isolated from samples of tissue collected from the fetal side of the placenta. In the targeted regions, we have identified 30, 24, and 29 CpG islands (CpGi) within sFLT-1, VEGF and PIGF genes, respectively. CpGi which are most methylated in the promoter regions of three genes were selected for the study from the database http://www.ensembl.org. RESULT(S): IUGR fetuses had significantly lower placental and fetal birth weight than controls. The promoter of sFLT-1 at three CpGi and VEGF at six CpGi were the regions with significant methylation differences between IUGR and control placentas. sFLT-1 was hypermethylated at 265 and 352 CpGi; however, hypermethylation was lower in IUGR group compared to control group at this position. sFLT-1 was hypomethylated at 456 CpGi in IUGR group and hypermethylated at the same region in control group. VEGF was hypomethylated at 668, 703, and 710 CpGi in control and IUGR groups; however, hypomethylation at these positions was significantly higher in control group compared to IUGR. 776, 845, and 863 CpGi of VEGF promoter were significantly hypermethylated in IUGR group whereas hypomethylated in control group. The methylation profile of PIGF did not differ between the groups. After adjustment for the factors known to affect fetal birth weight, DNA methylation of VEGF 668 CpGi had a significant negative association with fetal birth weight in the control and the IUGR group and a positive association with IUGR pregnancies. CONCLUSION(S): Our results do not support the hypothesis that altered DNA methylation in the placental angiogenic genes is a major mechanism generally involved in IUGR. Only a specific region (at 668 CpGi) corresponding to the promoter of VEGF may serve as an epigenetic marker of IUGR and may be involved in the mechanism of IUGR. Large sample-sized studies are needed to understand the effects of DNA methylation on placental gene function and how they might influence fetal growth.

A novel biochemical marker -OKL38- with its apoptotic and antioxidant properties for the development of PCOS and its related clinical implications.

Aim: To investigate the role of serum OKL38 levels in the development of polycystic ovary syndrome (PCOS) and clinical implications related to PCOS.Method: PCOS (n = 33) and ovulatory controls (n = 48) were recruited for the study. Anthropometric measurements were recorded, and blood samples for hormonal and biochemical parameters including serum OKL38 levels were obtained. The potential role of OKL38 on the development of PCOS, metabolic syndrome and cardiovascular disease (CVD) were investigated. Framingham risk score (FRS) was used for the determination of CVD risk.Results: Mean Ferriman-Gallway (FG) score, insulin, low-density lipoprotein (LDL), total cholesterol (TC) levels, and the homeostasis model assessment of insulin resistance index (HOMA-IR) were significantly increased (p < .05) in women with PCOS compared to controls. PCOS group had lower mean OKL38 level compared to controls (p < .0001) and OKL38 was negatively predictive for the diagnosis of PCOS after adjustment of variables that were significantly different between two groups. A negative association between OKL38 and metabolic syndrome in PCOS women was evident after adjustment for age, obesity, and abdominal obesity. OKL38 level was also negatively correlated with body mass index, waist-to-hip-ratio, fat composition, serum TC, LDL, free testosterone levels, FRS, and FG scores.Conclusion: OKL38 may have a partial role in the etiopathogenesis of PCOS and may protect development of metabolic syndrome and CVD in women with PCOS.

The association of type D personality and depression with infertility in women.

Purpose: Type D personality-defined as the presence of two personality characters, namely negative affectivity (NA) and social inhibition (SI)-is associated with various disorders. The 14-item Type D Scale (DS14), which consists of NA and SI subscales, can be used for the detection of the presence of Type D personality. The aim of our study was to investigate the association of Type D personality and depression with infertility in women.Method: A total of 324 women, 168 primary unexplained infertile women (92 patients undergoing in vitro fertilization (IVF) treatment and 76 undergoing intrauterine insemination (IUI) treatment) and 156 fertile controls were recruited. The 21-item Beck Depression Inventory (BDI-21) and DS14 were completed by all participants. The study was approved by Local Ethics Committee with the protocol number 72867572-050-218.Results: Depression and Type D personality were found to be significantly more prevalent in the infertile group than the fertile group. Type D was positively associated with infertility (OR = 2.34, 95% CI = 1.45-3.78, p < .0001), especially in the younger-aged (<35 years) population (OR = 2.59, 95% CI = 1.48-4.5, p = .001). After adjusting for the duration of marriage, age, obesity, educational level, and the same characteristics of the partner, the association between Type D personality and infertility persisted (OR = 2.56, 95% CI = 1.52-4.29, p < .001). The scores of the BDI-21 and NA subscale were found to be negatively correlated with age and partner's age. The BDI and SI scores, and the NA, SI, and Type D personality rates were similar between the IUI and the IVF groups; however, the NA score was higher, and depression was found to be more prevalent and severe in the IUI group than the IVF group.Conclusions: Type D personality could be positively associated with infertility, especially in younger-aged women.

The effect of anesthetic agents for oocyte pick-up on in vitro fertilization outcome: A retrospective study in a tertiary center.

OBJECTIVE: General anesthesia is used in most in vitro fertilization (IVF) clinics for oocyte pick-up (OPU), however, there is no consensus on type of anesthetic agent use among clinicians performing OPU. Therefore, we aimed to evaluate the effects of propofol, ketamine, or combination of propofol and ketamine (P + K) for OPU on IVF outcome. MATERIAL AND METHODS: Three hundred and thirty three women (n = 333) undergoing IVF treatment were retrospectively included and were evaluated in three groups depending on whether they received propofol (n = 217), or ketamine (n = 60), or P + K (n = 56) for anesthesia during OPU. RESULTS: Baseline characteristics and duration of anesthesia of each group were comparable except lower motile sperm percentage in the ketamine group compared to the propofol group (p = 0.002). Fertilization rate (FR) was decreased with ketamine compared to propofol (p = 0.013) and P + K (p = 0.008). After adjustment for sperm motility, this negative effect of ketamine on FR persisted. Implantation, clinical pregnancy, take-home baby rates, and oocyte retrieval parameters (number of total retrieved oocyte, metaphase II oocytes, embryo and methaphase II rate, and embryo quality) did not differ between the groups. Extended anesthesia duration (>30 min) was associated with low implantation (p = 0.04) and clinical pregnancy rates (p = 0.02). CONCLUSION: Ketamine use during OPU can affect FR compared to propofol and P + K. Long durations of anesthesia also seem to decrease implantation and clinical pregnancy rates.

The role of paternal obesity on the success of intracytoplasmic sperm injection cycle a tertiary IVF center in Turkey.

OBJECTIVE: To investigate the role of paternal obesity on intracytoplasmic sperm injection success. METHODS: The retrospective study was conducted in Suleyman Demirel University, Isparta, Turkey, from January 2015 to September 2017, and comprised data of infertile couples having undergone intracytoplasmic sperm injection cycle. The data was divided into three groups on the basis of paternal body mass index (BMI): normoweight NW (body mass index<23 kg/m2), overweight OW (body mass index= 23-24.9 kg/m2), and obese group (body mass index ≥25 kg/m2). Fertilisation rate, count and quality of embryos, implantation, clinical pregnancy, take-home baby, abortion rates and sperm parameters were evaluated. SPSS 20 was used for data analysis. RESULTS: Of the 374 cases, 45(12%) were in NW group, 78(21%) in OW, and 251(67%) in obese group. The overall mean age of males was 34.60}5.80 years, and mean body mass index was 26.84}3.57 kg/m2. There were no statistically significant differences in terms of fertilization rate, embryo count and quality, implantation, clinical pregnancy, take-home baby and abortion rates among the groups (p>0.05). Paternal obesity was not associated with sperm count and motility (p>0.05) either. Regression analysis showed that paternal obesity had no predictive effect on intracytoplasmic sperm injection success (p>0.05). CONCLUSIONS: Excess weight in male partner had no effect on intracytoplasmic sperm injection success.

Increased pancreatic-derived factor (PANDER) levels in gestational diabetes mellitus.

The aim of the study was to investigate the pancreatic-derived factor (PANDER) levels in healthy pregnant women and in pregnant women with gestational diabetes mellitus (GDM). A total of 50 women consecutively diagnosed with GDM and 30 randomly selected age-matched and gestational-age-matched healthy pregnant women were included in this cross-sectional study. Serum PANDER levels and other variables were analyzed. The age, the gestational age at the time, the blood sample was obtained and the hemoglobin A1c (HbA1c) levels of the GDM and control groups were similar. The body mass index (BMI), fasting blood glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), and serum PANDER levels were significantly higher in the GDM group than the control group. The optimal PANDER cutoff value was 227.2 ng/ml, and the ratios above this value were 100 and 86.6% for sensitivity and specificity, respectively (p=.0001). Serum PANDER levels were higher in women with GDM compared to the control group and were positively correlated with insulin, HOMA-IR, and HbA1c levels. These results suggest that PANDER might be considered a new biomarker for GDM.

Gremlin-1 and gremlin-2 levels in polycystic ovary syndrome and their clinical correlations.

Objective: Gremlin 1 and 2 regulate oocyte primordial follicle transition in animal models. The main objective of this study is to measure the blood levels of Gremlin 1 and 2 in the women with Polycystic Ovary Syndrome (PCOS). We also aimed to evaluate the association of these markers with hormonal and biochemical parameters of PCOS as interrupted folliculogenesis in those women is related to metabolic dysfunction. Material and methods: Fifty women with PCOS were diagnosed according to Rotterdam criteria, and thirty age-matched female controls were included in this prospective study. Gremlin 1 and 2 levels along with hormonal and metabolic parameters were compared between PCOS and control groups. Results: Serum Gremlin 1 levels were significantly higher in the PCOS group than in the control group (p = .001). Gremlin 2 levels were similar between the groups. Besides, there was a significant positive correlation between Gremlin 1 and insulin levels, Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) and waist to hip ratio (WHR) (r = 0.305; r = 0.297; r = 0.303, respectively). Conclusion: Our data suggest that Gremlin 1 may be the key regulator in the pathogenesis of PCOS. In future, Gremlin 1 may be a novel therapeutic target for the treatment of PCOS.

Increased levels of the novel hepatokine fetuin B in patients with intrahepatic cholestasis of pregnancy.

OBJECTIVES: To investigate liver-derived plasma protein fetuin B levels in healthy pregnant women and pregnant women with intrahepatic cholestasis of pregnancy (ICP). MATERIALS AND METHODS: Forty women with ICP and 40 healthy pregnant women were included in this cross-sectional study. The serum fetuin B levels of these patients were analyzed. The patients were followed up to delivery. RESULTS: Maternal age, gravida, parity, BMI at assessment, and gestational age at blood sampling were similar between the ICP and control groups (p > .05). However, the gestational age at delivery and the birth weight were significantly lower in the ICP group (p < .05). Total bile acid (TBA) levels and liver function tests were significantly higher in the ICP group than in the control group (p < .0001 and < .0001, respectively). In addition, serum fetuin B concentrations were significantly higher in the ICP group than in the control group (p < .0001). The best cutoff for fetuin B serum concentration was 5540.2 pg/mL. Serum values greater than this threshold had 80% sensitivity and 65% specificity for the diagnosis of ICP. CONCLUSIONS: Serum fetuin B was higher in patients with ICP compared to healthy pregnant women and might be a new biomarker.

Maternal serum AMP-activated protein kinase levels in mild and severe preeclampsia.

OBJECTIVE: To investigate Phosphorylated adenosine monophosphate activated protein kinase (AMPK) levels in healthy pregnant women and pregnant women with preeclampsia (PE). METHODS: Twenty-eight women with mild-PE, 22 with severe-PE, and 30 normotensive controls were included in this cross-sectional study. The serum AMPK levels of these patients were analyzed. The patients were followed up to delivery. RESULTS: No statistically significant difference was found between the groups for age, gravida, parity, and gestational age at the time the blood samples were obtained (p > .05). No significant difference between the group with mild-PE and the control group was found, while in the severe-PE group, serum AMPK levels were significantly higher relative to both the mild-PE and control groups (p < .001 and p < .001, respectively). No correlation was detected between serum AMPK levels and age, body mass index (BMI), and gestational age at the time the blood samples were collected. A negative correlation was found between AMPK levels and gestational week and birthweight at delivery, while a positive correlation was detected between systolic and diastolic blood pressures and AMPK levels. CONCLUSIONS: Serum AMPK was higher in patients with severe-PE compared with healthy pregnant women and patients with PE without severe features so it might be a new biomarker for the prediction of disease and its severity.

Effect of DNA damage of cumulus oophorus cells and lymphocytes analyzed by alkaline comet assay on oocyte quality and intracytoplasmic sperm injection success among patients with polycystic ovary syndrome.

AIM: Cumulus oophorus cells (COC) exhibit a close relationship with the oocytes. We aimed to determine the role of the DNA integrity of COC and lymphocytes on the oocyte and embryo quality and intracytoplasmic sperm injection (ICSI) success. METHODS: The COC obtained with the mechanical denudation of each oocyte and the lymphocytes obtained on oocyte retrieval day from 69 infertile polycystic ovary syndrome (PCOS) patients were used. The tail length, tail moment and tail DNA percentage were evaluated using an alkaline comet assay. The oocytes and embryos were graded. Clinical pregnancy was defined as the presence of a gestational sac with a beating heart. RESULTS: All of the DNA integrity parameters of the COC and lymphocytes were similar between the good and poor quality oocytes and between the good and poor quality embryos. There was no relationship between the DNA damage parameters and the fertilization and clinical pregnancy. The day 2 hormone levels, body mass index and age were negatively correlated with the DNA integrity parameters. No links were found between the embryo and oocyte scores and the DNA damage parameters. CONCLUSION: The DNA integrity of the COC and lymphocytes did not seem to be related to the oocyte and embryo quality and ICSI success.

The role of complete blood inflammation markers in the prediction of spontaneous abortion.

OBJECTIVE: To investigate relationships between spontaneous abortion and complete blood count inflammation markers and their role in predicting spontaneous abortion. METHODS: This study was conducted at Department of Obstetrics and Gynecology between January 2012 and January 2017. A total of 570 participants, 325 diagnosed with spontaneous abortion and 245 control patients who underwent timely births were included into our study. The complete blood count inflammation markers included white blood cell (WBC), neutrophil (N), lymphocyte (L), neutrophil-lymphocyte ratio (NLR), mean platelet volume (MPV) and platelet-lymphocyte ratio level (PLR) were recorded. RESULTS: There was difference between the abortion groups and control groups in terms of complete blood count (CBC) inflammation markers, including WBC, PLT, neutrophil, lymphocyte, NLR, PLR, and MPV. We found decreased MPV, PLR levels and increased N, L and NLR in the first. and second. Abortion groups compared with the control group. WBC, N, L and NLR were positive predictive markers, and albeit with low sensitivity and specificity, MPV, PLR were found to be a negative predictive marker for the evaluation of spontaneous abortion. CONCLUSIONS: Unlike several difficult and invasive tests, a CBC is a simple, inexpensive and easily available test. CBC inflammation markers, including WBC, N, L, NLR, PLR, and MPV, which were evaluated at the sixth gestational week, can be used for the risk assessment of spontaneous abortion in pregnancy.

The role of ADAMTS-2, collagen type-1, TIMP-3 and papilin levels of uterosacral and cardinal ligaments in the etiopathogenesis of pelvic organ prolapse among women without stress urinary incontinence.

OBJECTIVE(S): To investigate the potential role of 'a disintegrin-like and metalloproteinase with thrombospondin type motifs-2 (ADAMTS-2), collagen type-1, tissue inhibitor of metalloproteinases-3 (TIMP-3) and papilin' levels in the uterosacral ligament (USL) and cardinal ligament (CL) of the uterus on the etiopathogenesis of pelvic organ prolapse (POP) among postmenopausal women without stress urinary incontinence (SUI). STUDY DESIGN: A total of 45 postmenopausal women, 22 diagnosed as POP stage III-IV and 23 age- and body mass index (BMI)-matched controls referred for hysterectomy due to POP or benign gynecological disease, respectively, were recruited prospectively for our study. The biopsies of the USL and CL were obtained during hysterectomy. ADAMTS-2, collagen type-1, TIMP-3 and papilin levels were determined by enzyme-linked immunosorbent assay (ELISA) method after tissue homogenization. We excluded patients who smoked or presented with SUI. RESULTS: There were no differences in terms of demographic features including age, BMI, obesity, duration of menopause, gravidity, parity, delivery modes and family history for POP between the POP and non-POP groups. Significant differences in the levels of ADAMTS-2, collagen type-1, TIMP-3 and papilin of USL were noted among the groups. Females with POP had lower levels of ADAMTS-2, collagen type-1, TIMP-3 and papilin in the USL compared to non-POP females. All investigated markers in the CL were also decreased in the POP group, but this relationship was not statistically significant. When age, duration of menopause, gravidity, parity and obesity were taken as covariates, only the USL papilin levels were negatively predictive for the development of POP. CONCLUSION(S): ADAMTS-2, collagen type-1, TIMP-3 and papilin levels of the USL play essential roles in the etiopathogenesis of POP among postmenopausal women without SUI. Moreover, significantly decreased USL papilin levels in females with POP suggest the importance of the USL and the impact of papilin on the development of POP.

The Role of Follicular Fluid Thiol/Disulphide Homeostasis in Polycystic Ovary Syndrome

BACKGROUND: Oxidative stress has been proposed as a potential trigger in the etiopathogenesis of polycystic ovary syndrome-related infertility. Thiol/disulphide homeostasis, a recently identified oxidative stress marker, is one of the antioxidant mechanism in humans with critical roles in folliculogenesis and ovulation. AIMS: To investigate follicular fluid thiol/disulphide homeostasis in the etiopathogenesis of polycystic ovary syndrome and to determine its association with in vitro fertilization outcome. The study procedures were approved by the local ethics committee. STUDY DESIGN: Cross-sectional study. Methods: Follicular fluid from 22 women with polycystic ovary syndrome and 20 ovulatory controls undergoing in vitro fertilization treatment was sampled. Thiol/disulphide homeostasis was analyzed via a novel spectrophotometric method. Results: Follicular native thiol levels, as well as the native thiol/total thiol ratio, were lower in the polycystic ovary syndrome group than in the non-polycystic ovary syndrome group (p=0.041 and p<0.0001, respectively). Disulphide levels, disulphide/native thiol, and disulphide/total thiol ratios were increased in the polycystic ovary syndrome group (p<0.0001). A positive correlation between the fertilization rate and native thiol (p=0.01, r=0.53) and total thiol (p=0.01, r=0.052) among polycystic ovary syndrome patients was found. A positive predictive effect of native thiol level on the fertilization rate in the polycystic ovary syndrome group was also found (p=0.03, ß=0.45, 95% CI= 0.031-0.643). Conclusion: Deterioration of thiol/disulphide homeostasis, especially elevated disulphide levels, could be one of the etiopathogenetic mechanisms in polycystic ovary syndrome. Increased native thiol levels are related to the fertilization rate among polycystic ovary syndrome patients and are positive predictors of the fertilization rate among polycystic ovary syndrome patients. Improvement of thiol/disulphide homeostasis could be important in the treatment of polycystic ovary syndrome to increase in vitro fertilization success.
