RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

PURPOSE: The aim of this study was to analyze serum a disintegrin-like and metalloproteinase with thrombospondin-type motifs-1 (ADAMTS-1) and aggrecan levels in adolescents and younger-aged females with polycystic ovary syndrome (PCOS) compared with ovulatory controls to determine whether these are potential markers for the prediction of PCOS diagnosis. We also aimed to determine whether they could predict the development of clinical implications associated with PCOS. METHOD: PCOS (n = 49) and ovulatory age-matched controls (n = 41) (mean age, 18.6 ± 2.5) were recruited. Anthropometric measurements were recorded and biochemical parameters were analyzed. Serum ADAMTS-1 and aggrecan levels were determined with enzyme-linked immunosorbent assay. The predictive effects of ADAMTS-1 and aggrecan on the diagnosis of PCOS and for the development of cardiovascular disease (CVD) risk and insulin resistance (IR) were evaluated. The correlation between investigated markers and anthropometric, biochemical, and hormonal parameters were also investigated. RESULTS: Mean serum ADAMTS-1 level was increased in adolescents and younger-aged females with PCOS compared to ovulatory controls. An elevated ADAMTS-1 level was positive predictive of the diagnosis of PCOS with the best cut-off value of 2.5 ng/ml (sensitivity 69% and specificity 78%). A positive predictive role of ADAMTS-1 on the development of CVD risk and IR was found among all patients. Serum ADAMTS-1 and aggrecan levels were significantly and positively correlated with each other. CONCLUSION: Increased levels of ADAMTS-1 could be a potential marker for the etiopathogenesis of PCOS in adolescents and younger-aged females and predict the development of CVD risk and IR among all patients with the same age.

RESUMO

Cigarette smoking (CS) has some detrimental effects that occur via oxidative stress (OS). The aim of this work was to demonstrate the pathological and immunohistochemical effects of CS and the protective effects of a strong antioxidant alpha lipoic acid (ALA) on CS-induced genital system changes in a rat model. Twenty-eight female rats were randomly allocated to three groups as control, CS-exposed, and CS-exposed and ALA-treated. Reproductive tract organs were collected for biochemical and pathological examinations. In the CS group, OS markers increased in the tissues of both the ovary and fallopian tubes. Decreased follicle numbers in the ovary, marked cilial loss in the fallopian tubes, and pathologic changes in the uterus were observed in the CS group. Positive calcitonin gene-related peptide (CGRP), caspase 3α, hypoxia-inducible factor 1α (HIF-1α), tumor necrosis factor-α (TNF-α) immunoreactions were observed in uterine tissues and HIF-1α immunoreactions in tubal and uterine epithelial cells of the CS group. ALA reversed all these findings effectively. CS has negative effects on the female reproductive system via HIF-1α in tuba uterina and HIF-1α, HIF-2α, TNF-α, caspase 3, and CGRP in the uterus, and ALA could protect against the negative effects of CS on the female reproductive system.

RESUMO

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.

RESUMO

PURPOSE: Polycystic ovary syndrome (PCOS) is the most common cause of ovulatory dysfunction and female infertility. The etiopathogenetic mechanisms of PCOS have been studied for many years, although exact causes remain unclear. It has been demonstrated that proteoglycan degradation by a disintegrin-like metalloproteinase with thrombospondin type motifs-1 (ADAMTS-1) is essential for ovulation and fertilization. The objective of our study is to analyze the levels of ADAMTS-1 and aggrecan in the follicular fluid (FF) of PCOS patients compared with normal ovulatory women and to determine whether these markers could be a predictor of in vitro fertilization (IVF) success in PCOS patients. METHODS: Women with PCOS (n = 21) and normal ovulatory controls (n = 22) undergoing IVF treatment were recruited. ADAMTS-1 and aggrecan levels were analyzed with enzyme-linked immunosorbent assay (ELISA) and compared between PCOS and normal ovulatory controls. The predictor effect of ADAMTS-1 and aggrecan on fertilization rate and implantation was evaluated. RESULTS: FF ADAMTS-1 and aggrecan levels increased in women with PCOS compared to controls. Elevated ADAMTS-1 levels but not aggrecan were related to increased implantation in PCOS. CONCLUSION: Our study demonstrated that altered levels of ADAMTS-1 and aggrecan may have a partial role in the etiopathogenesis of PCOS, and ADAMTS-1 could be a predictive marker for implantation success in PCOS patients.

RESUMO

BACKGROUND: Matrix metalloproteinase-2 and -9, known as gelatinases, are considered to be essential for tissue remodelling during the reproductive process. However, their role in reproduction is unclear. AIMS: In the present study, we aimed to investigate the relationship between follicular fluid gelatinase levels and oocyte quality and fertilization, and to compare the activities of gelatinase levels with different drug stimulation protocols. METHODS: We evaluated 60 women with unexplained infertility who underwent in vitro fertilization (IVF) treatment. Thirty patients underwent a gonadotropin-releasing hormone (GnRH) agonist protocol and 30 underwent a GnRH antagonist protocol. Follicular fluid was obtained during oocyte retrieval. Oocyte quality was determined using light microscopy, and oocytes were considered to be fertilized when two pronuclei were present. Gelatinase activities were measured using commercial enzyme-linked immunosorbent assay kits. The study was partially supported by the Scientific Research Unit of Suleyman Demirel University (Protocol Number: 3620-TU1-13), and all procedures were conducted with the approval of the Suleyman Demirel University Local Ethics Board. Statistical analyses of the data were performed using the independent t test, Fisher exact test, Mann-Whitney U test, one-way ANOVA, and posthoc least significant difference. RESULTS: Follicular fluid gelatinase levels were significantly higher for agonist drug administration (p = 0.001), and a positive correlation was observed between matrix metalloproteinase-9 levels and oocyte grade (p = 0.01). Moreover, a positive relationship between matrix metalloproteinase-9 levels and fertilization was observed (p = 0.02). CONCLUSION: Follicular fluid gelatinase activities, particularly MMP-9 activity, might be a predictor of oocyte quality and IVF success.

RESUMO

Oxidative stress is important for promoting oocyte maturation and ovulation within the follicle through calcium ion (Ca(2+)) influx. The relationship between antioxidant and cytosolic Ca(2+) levels and oocyte quality and fertilisation rate in the granulosa cells of patients undergoing in vitro fertilisation was investigated. Granulosa cells were collected from 33 patients. Cytosolic free Ca(2+) ([Ca(2+)]i) concentration, lipid peroxidation, reduced glutathione, glutathione peroxidase and oocyte quality were measured in the granulosa cells. The relationship between two drug protocols was also examined (gonadotrophin-releasing hormone antagonist and agonist protocols) and the same parameters investigated. The [Ca(2+)]i concentration (P<0.001), glutathione (P<0.05) and oocyte quality (P<0.001) values were significantly higher in the fertilised group than in the non-fertilised group, although glutathione peroxidase activity was significantly (P<0.05) higher in the non-fertilised group than in the fertilised group. The [Ca(2+)]i concentrations were also higher (P<0.001) in the good-quality oocyte groups than in the poor-quality oocyte group. There was no correlation between the two drug protocols and investigated parameters. In conclusion, it was observed that high glutathione and cytosolic Ca(2+) concentrations in granulosa cells of patients undergoing in vitro fertilisation tended to increase the fertilisation potential of oocytes.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE(S): The purpose of our study was to evaluate whether the inflammatory parameters of complete blood count (CBC), including white blood cell (WBC), neutrophil-to-lymphocyte-ratio (NLR), platelet-to-lymphocyte-ratio (PLR), and mean platelet volume (MPV), had potential roles in the etiopathogenesis of unexplained infertility (UI) among nonobese women. We also aimed to investigate whether there could be an association between these markers and in vitro fertilization (IVF) success among nonobese women with UI. MATERIALS AND METHODS: This was a retrospective clinical trial, including a total of 246 nonobese patients undergoing IVF procedures, 121 diagnosed as UI and 125 were age and body mass index (BMI) matched infertile controls who received IVF for tubal factor and male factor. Only normoweight (BMI<25 kg/m2) participants were recruited to our study to rule out the effect of obesity on inflammation. CBC parameters were evaluated before ovarian stimulation protocol. RESULTS: All of the inflammatory parameters of CBC were distributed homogenously between groups. Platelet and lymphocyte count were positively correlated with fertilization rate (FR) among UI patients. Embryo count was positively correlated with platelet and negatively correlated with MPV. PLR was also positively correlated with luteinizing hormone on day 3 of cycle. After adjustment for age and BMI, there was a positive association between lymphocyte count and FR and a negative association between PLR and implantation among UI patients. None of the inflammatory markers of CBC were predictive for clinical pregnancy, take home baby, and clinical and biochemical abortion rates among nonobese UI patients. CONCLUSION: Increased levels of CBC inflammation markers may have a negative impact on IVF outcomes among nonobese women with UI.

RESUMO

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.
