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

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

Expression of Immunomodulatory Molecules PD-1, PD-L1, and PD-L2, and their Relationship With Clinicopathologic Characteristics in Endometrial Cancer.

Chemotherapeutic agents are not very effective in treating advanced endometrial cancers (ECs). Recent studies have demonstrated the immune evasion mechanism of tumors and possible remedies. Programmed cell death protein 1 (PD-1), programmed death ligand 1 (PD-L1), and programmed death ligand 2 (PD-L2) are immunomodulator molecules that have been the focus of research in lung cancer, melanoma, and renal cell cancer. However, there are few studies concerning EC. This retrospective study aimed to determine PD-1, PD-L1, and PD-L2 expression immunohistochemically in EC, and to study their correlation with clinicopathologic tumor characteristics. This study comprised 127 patients with EC. Anti PD-1, PD-L1, and PD-L2 antibodies were examined immunohistochemically on sections obtained from tissue microarray paraffin blocks. No staining with PD-1 in tumor cells was seen; however, we found positive staining in tumor cells at 36.2% with PD-L1 and 64.4% with PD-L2, and at 61.6% with PD-1, 36.2% with PD-L1, and 93.2% with PD-L2 in immune cells. When comparing staining and clinicopathologic findings, most of the PD-L1 negative tumors (both in tumor and immune cells) were FIGO Stage I, which was significantly higher than stage II-III-IV tumors (P<0.05). There was a statistically significant association between the FIGO grade and the PD-L1 score in immune cells (P=0.009), and between staining of PD-1, PD-L1, and PD-L2 and age (P=0.004, 0.013, and 0.043, respectively). Interaction between PD-1, PD-L1, and PD-L2 may be a potential target for immunotherapy in elderly and advanced stage EC patients.

Soluble urokinase-type plasminogen activator receptor (suPAR) and interleukin-6 levels in hyperemesis gravidarum.

BACKGROUND: The aim was to compare serum soluble urokinase-type plasminogen activator receptor (suPAR) levels as well as interleukin-6 levels (IL-6) in pregnant women with hyperemesis gravidarum (HG) and asymptomatic pregnant women. METHODS: Our study population consists of voluntary first trimester-pregnant women who applied to the outpatient clinic of the department of obstetrics and gynecology of Ankara Ataturk Training and Research Hospital. Between February and May 2016, 60 pregnant women were included in our prospective study. Serum suPAR and IL-6 levels were evaluated with the ELISA method. Twenty-nine pregnant women with HG and 31 asymptomatic pregnant women were included in the study. RESULTS: Serum suPAR level in the HG group was measured as 0.36 ± 0.56 ng/ml, whereas this level in the healthy pregnant control group was measured as 0.15 ± 0.15 ng/ml (p < 0.05). The interleukin-6 level in the HG group was 5.69 ± 2.16 pg/ml, whereas in the control group it was measured as 3.88 ± 0.28 pg/ml (p < 0.05). CONCLUSION: Serum suPAR and IL-6 levels proved to be high in the HG group. It is likely that suPAR could play a role in the etiopathogenesis of hyperemesis gravidarum.

Sonographic measurement of the fetal thymus: Relationship with maternal obesity.

BACKGROUND: The purpose of this study was to evaluate the influence of maternal obesity on the size of the fetal thymus. METHODS: The study population consisted of 138 pregnant women who were divided into two groups based on their body mass index (BMI): Normal-weight group (n = 97; BMI: 18-25 kg/m2 ) and obese group (n = 41; BMI: ≥ 30 kg/m2 ). All participants underwent routine second-trimester prenatal ultrasound (US) screening at 20-25 weeks of gestation. Differences in US measurement of fetal thymus, fetal anthropometric measurements, subcutaneous adipose tissue thickness, fetal weight, gestational age, white blood cell count, and C-reactive protein (CRP) values between groups were compared. RESULTS: The mean thymus size was 18.7 ± 2.9 mm for normal-weight group, and 21.6 ± 3.7 mm for the obese group (p < 0.001). CRP values were also significantly different between groups (6.8 ± 4.4 mg/dl for normal-weight group, 14.8 ± 1.8 mg/dl for obese group, p < 0.001). CONCLUSIONS: Fetal thymus size was increased in obese women, and this increase may indicate immunologic abnormalities in fetuses. However, future large-scale studies are necessary to support this association. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:277-281, 2017.

Dynamic Thiol-Disulphide Status in Polycystic Ovary Syndrome and Its Association with the Pathogenesis of the Disease.

BACKGROUND/AIMS: This study aims to examine the differences in plasma thiol-disulphide levels that are related to oxidative stress among obese and nonobese women with polycystic ovary syndrome (PCOS) and their age/body mass index (BMI)-matched healthy controls. METHODS: The participants were divided into 4 groups based on BMI (nonobese and obese). Serum thiol and disulphide levels were compared among groups. RESULTS: Serum thiols were found higher in the obese PCOS group than those in the obese control group in the study (thiol: 407.33 ± 46.25 vs. 365.67 ± 67.03 µmol/l, p = 0.014). Disulphide levels were observed to be decreased in the obese PCOS group relative to its control (21.39 ± 1.33 vs. 23.53 ± 8.47 µmol/l, p = 0.021). Serum thiol levels were found to be higher in the nonobese PCOS group compared to nonobese controls (thiol: 434.7 ± 46.92 vs. 422.94 ± 46.61 µmol/l, p = 0.031). Significant differences of disulphide levels between the nonobese PCOS group and the nonobese control group were observed (18.07 ± 1.93 vs. 20.68 ± 3.79 µmol/l, p = 0.027). CONCLUSION: High antioxidant levels in women with PCOS may be related to either mechanisms involving anovulation, multiple follicular development, and apoptosis or to their compensatory system against oxidative load arising from obesity and overweightness.

A Rare Clinical Presentation of Giant Bilateral Labial Fibroepithelial Stromal Polyps in Patient with Psoriasis Disease.

Fibroepithelial polyps (FEPs) are rarely seen lesions of the lower female genital tract with polypoid proliferations of stroma. These tumors usually present in the vulvovaginal region of the reproductive aged women. In this presentation, we report a case of a psoriatic woman who developed unusual multiple polypoid lesions approximately 15 cm in size arising from both left and right labia minora and unique connection of FEPs with psoriasis disease.

Levels of thrombin-activatable fibrinolysis inhibitor and platelet-activating factor in recurrent pregnancy loss patients.

OBJECTIVE: The aim of this study was to investigate factors associated with thrombosis that may contribute to recurrent pregnancy loss (habitual abortion), specifically differences in serum levels of platelet-activating factor and thrombin-activatable fibrinolysis inhibitor (carboxypeptidase B2) between women with a history of recurrent miscarriage and those with no recurrent miscarriage history. MATERIALS AND METHODS: A case-controlled, prospective study design was adopted to compare women with a history of two or more first-trimester miscarriages (n = 42) with those with no history of recurrent miscarriage (n = 36). Participants were recruited from the Department of Obstetrics and Gynecology of Turgut Ozal University Hospital. Platelet-activating factor and thrombin-activatable fibrinolysis inhibitor levels in serum samples were measured by an enzyme-linked immunosorbent assay. RESULTS: Platelet-activating factor levels were significantly (p = 0.018) higher in the recurrent miscarriage group. There was no difference in levels of thrombin-activatable fibrinolysis inhibitor expression between the groups. CONCLUSION: Platelet-activating factor is significantly higher in serum of patients with a history of recurrent miscarriage than in those without such a history, with potential implications for placental function and fetal growth, which could be relevant to miscarriage recurrence. Larger studies are indicated to further examine these findings.

Evaluation of oxidative stress markers and intra-extracellular antioxidant activities in patients with endometriosis.

OBJECTIVE: The aim of the study is to evaluate alterations in intracellular and extracellular antioxidant enzymes activities and serum oxidative stress markers in patients with endometriosis. STUDY DESIGN: The current prospective study consisted of 31 female patients with endometriosis and 27 healthy controls. Serum total thiol, native thiol, disulphide, catalase, myeloperoxidase, and ceruloplasmin concentrations were measured. Laboratory and clinical data of all participants were recorded to compare the differences between the study and the control groups. RESULTS: Serum native thiol and total thiol levels in the study group were significantly lower than those in the control group [(p=0.009, p=0.03, respectively)]. Serum catalase levels are significantly higher in patients with endometriosis comparing to the control group (p=0.009). CONCLUSIONS: The finding that significant differences in serum total thiol, native thiol, and catalase levels observed in endometriotic patients supports that oxidative stress carries weigh in the pathophysiological aspects of endometriosis. Also significantly low levels of extracellular antioxidants and significantly high levels of intracellular antioxidants in endometriotic patients may arise from differences of free radicals in endometriosis and the activity levels of endometriosis. These non-invasive serum markers might give us an opportunity to monitor the disease's progress during the treatment.

Differentiation between benign and malignant ovarian masses in the preoperative period using neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios.

The aim of this study was to evaluate the association between preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) and the pathological diagnosis of adnexal masses. The predictive effect of inflammatory markers on epithelial ovarian cancer was also investigated. The present study included a total of 306 patients with adnexal masses who underwent surgical resection and the diagnosis was based on pathological investigation. The patients were divided into six groups based on their pathological findings and compared with respect to their NLR and PLR values. We used receiver-operating characteristic curves to calculate optimal cut-off values for NLR and PLR to predict ovarian cancer preoperatively. Patients with ovarian cancer exhibited significantly higher NLR and PLR values (P<0.05 and P<0.001, respectively). The multivariate analysis demonstrated that higher NLR and PLR values predicted ovarian cancer at the cut-off value of 3.35, sensitivity of 55% and specificity of 81% for NLR [95% confidence interval (CI): 0.544-0.752, P<0.05] and at the cut-off value of 572.9, sensitivity of 100% and specificity of 0.38% for PLR (95% CI: 0.192-0. 381, P=0.001). Therefore, preoperative NLR and PLR values may help identify ovarian cancer in patients with adnexal masses.

Multiple sclerosis; a disease of reproductive-aged women and the dilemma involving contraceptive methods.

Multiple sclerosis (MS) is an autoimmune disorder characterized by chronic inflammation in the central nerves system. Because the disease predominantly affects women of reproductive ages, having knowledge about contraception options for MS patients can make clinicians provide better counseling. Although most contraceptive methods are generally accepted as safe and effective in MS patients, recent studies have raised questions about their potential adverse effects on the disease. The use of contraceptive methods to avoid unintended pregnancies is crucial in MS patients, particularly during the relapse phase of the disease or the time when the disease is not completely under control. This review investigates the contraception options and their effects on female MS patients. Providing appropriate contraception options to multiple sclerosis patients will be one of the most challenging issues for clinicians to deal with. Recent studies have raised questions that the use of hormonal contraceptives may at least partly contribute to the rise in incidence of MS in women. This review investigates the contraception options and their effects on female MS patients.

Is There Any Relationship between Plasma Pentraxin 3 Levels and Gestational Diabetes Mellitus?

BACKGROUND: Pentraxin 3 (PTX3) is a novel vascular inflammatory marker which increases in vascular events such as diabetes mellitus. The aim of this study was to investigate the relationship between serum PTX3 levels and gestational diabetes mellitus (GDM). METHODS: This prospective observational study was comprised of 88 pregnant women with singleton pregnancies. The subjects were classified into 3 groups according to their response to a 50-gram glucose challenge test (GCT) and a 100-gram oral glucose tolerance test: control group (n = 28), impaired glucose tolerance group (n = 30), and GDM group (n = 30). Serum PTX3 levels were measured to examine the relationship between GDM and GCT values. RESULTS: Significant differences in PTX3 levels were observed among the 3 groups in the sample (F = 7.598; p = 0.001). The mean PTX3 value was found to be significantly higher in the GDM group (3.17 ± 1.16 ng/ml) than in the control group (2.20 ± 0.83 ng/ml; p = 0.001). A significant positive correlation between PTX3 and GCT values was detected (r = 0.289; p = 0.008). CONCLUSION: Maternal serum PTX3 levels were found to be significantly related to high blood glucose levels. This may be an indicator of vascular pathology in GDM around the time of an oral glucose tolerance test.

Can hyaluronan binding assay predict the outcome of intrauterine insemination in couples with unexplained or mild male factor infertility?

BACKGROUND: The purpose of this study was to evaluate the prognostic effect of Hyaluronan Binding Assay (HBA) which has been used as a method of sperm selection for intracytoplasmic sperm injection procedure, on the outcome of intrauterine insemination (IUI) in couples with unexplained or mild male factor infertility. METHODS: 77 infertile couples were enrolled in our study. On the day of IUI procedure, HBA test was performed by using fresh semen samples, and the rates of sperm binding to HBA were calculated. HBA values and semen parameters were compared. Fisher exact test was used to evaluate the relationship between HBA ratio and pregnancy status. Mann-Whitney U test was used to compare quantitative variables between pregnant and non-pregnant groups. The p < 0.05 was considered statistically significant. RESULTS: In this study, HBA ratio was 69(29.25%) and pregnancy rate was 14.29%. A significant positive correlation between HBA and total motile sperm count, inseminating sperm count, progressive motility, morphology, and sperm concentration (p < 0.001, p < 0.001, p:0.007, p < 0.003, p:0.003 respectively) was observed. Although HBA values in pregnant group were higher than those in non-pregnant group, this result did not reach the statistically significant level (HBA: 67(20%) for non-pregnant group, 80.5(21.3%) for pregnant group). Also, no relationship between HBA values and pregnancy status was found. Moreover, there was no significant correlation between pregnancy status and HBA ratios based on the suggested cut-off value of 60 in literature (p = 0.425). CONCLUSION: HBA does not predict the IUI outcome in couples with unexplained infertility or mild male factor infertility, but it can be used together with semen parameters to verify sperm quality.

Preoperative Neutrophil-to-Lymphocyte Ratio Has a Better Predictive Capacity in Diagnosing Tubo-Ovarian Abscess.

BACKGROUND: The aim of this study is to identify the inflammatory markers which predict a tubo-ovarian abscess (TOA) in the most accurate way. METHODS: This study involves 312 women. Preoperative inflammatory markers in the study group were compared with those in the healthy control group to identify the most efficient predictor of TOA with a high sensitivity and specificity. The recommended cutoff values of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), white blood cell count, and red cell distribution width were determined using receiver operating characteristic curve (ROC) analyses. RESULTS: The area under the curve (AUC = 0.99) in the ROC analysis was found to be statistically significant for NLR (p < 0.001) with a cutoff value of ≥4.15 (95% CI 0.97-1.00, sensitivity 95.2%, specificity 99.4%). The positive predictive value of NLR was 99.2%, and the negative predictive value was 96.7% (p < 0.001). The recommended threshold for PLR was found to be 164.37 (AUC = 0.95, 95% CI 0.93-0.98, sensitivity 86.7%, specificity 92%), and the cutoff point of the white blood cell count in the ROC analysis was 9.55 × 103/µl (AUC = 0.90, 95% CI 0.87-0.95, sensitivity 78.68%, specificity 96.68%). CONCLUSION: Preoperative NLR and PLR improve the predictive value of serum markers for the presence of TOA.

Unexpected fetal demise despite the reactive nonstress test during the conservative management of acute pancreatitis in pregnancy.

INTRODUCTION: Dealing with acute pancreatitis in pregnancy is a challenging problem due to unexpected nature of the disease. PRESENTATION OF CASE: We report a complicated case of a 29-year-old pregnant woman with a mild acute pancreatitis whose pregnancy ended up with an unexpected fetal demise at her 34th gestational week. This unfortunate outcome led us reconsider our obstetrical approach to acute pancreatitis during pregnancy. CONCLUSION: Based on this unfortunate event, we now think that obstetricians should keep in mind that even in the presence of reassuring NST and biophysical profile assessment, an unpredictable fetal loss can occur during the medical management of the pregnancies complicated with mild acute pancreatitis. DISCUSSION: The subject patient of this case report was diagnosed with mild AP and underwent conservative medical management. Since the patient was stable and fetal well-being was confirmed with BPP and NST, the termination of pregnancy was out of question at that time. The occurrence of unexpected fetal death despite assuring parameters led us reconsider the approach to the pregnant women with mild AP.

Effect of music on labor pain relief, anxiety level and postpartum analgesic requirement: a randomized controlled clinical trial.

BACKGROUND/AIMS: The control of labor pain and the prevention of suffering are major concerns of clinicians and their patients. The aim of this study was to evaluate the effect of music on labor pain and anxiety, maternal hemodynamics, fetal-neonatal parameters and postpartum analgesic requirement in primiparous women. METHODS: Overall, 156 primiparous women who expected vaginal delivery were recruited and randomly assigned to a music group (n = 77) or a control group (n = 79). Women in the music group listened to music during labor. Pain intensity and anxiety level were measured using a visual analogue scale (0-10 cm). The two groups were compared in terms of pain severity, anxiety level, maternal hemodynamics, fetal-neonatal parameters and postpartum analgesic requirement. RESULTS: Mothers in the music therapy group had a lower level of pain and anxiety compared with those in the control group at all stages of labor (p < 0.001). A significant difference was observed between the two groups in terms of maternal hemodynamics and fetal heart rate after intervention (p < 0.01). Postpartum analgesic requirement significantly decreased in the music therapy group (p < 0.01). CONCLUSION: Listening to music during labor has a positive impact on labor pain and anxiety, maternal-fetal parameters and analgesic requirement.

Effect of music therapy during vaginal delivery on postpartum pain relief and mental health.

BACKGROUND: Childbirth is an important experience in a woman's life, and unfavorable birth experiences have been shown to negatively impact postpartum maternal health. Aim of this study was to evaluate the effects of music therapy on postpartum pain, anxiety level, satisfaction and early pospartum depression rate. METHODS: Totally 161 primiparous women were recruited and randomized either music group (n=80) or a control group (n=81). Women in the music group listened to self-selected music during labor. Postpartum pain intensity, anxiety level and satisfaction rate were measured using the visual analog scale (VAS), postpartum depression rate was assessed with Edinburg Postpartum Depression Scale (EPDS) at postpartum day one and day eight. RESULTS: Mothers in the music therapy group had a lower level of postpartum pain and anxiety than the control group and it was statistically significant at all time intervals (1, 4, 8, 16 and 24h, p<0.001). A significant difference was observed between the two groups in terms of satisfaction rate (p<0.001) and postpartum depression rate at postpartum day one and day eight (p<0.05). LIMITATIONS: We only measured the effect of music therapy on early postpartum depression rate. Effect of music on late postpartum depression rate should be investigated in future. CONCLUSIONS: Using music therapy during labor decreased postpartum anxiety and pain, increased the satisfaction with childbirth and reduced early postpartum depression rate. Music therapy can be clinically recommended as an alternative, safe, easy and enjoyable nonpharmacological method for postpartum well-being.

Evaluation of risk factors and effect of physical activity in caesarean section in nulliparous women.

OBJECTIVE: The aim of this study was to evaluate risk factors for caesarean section (CS) in nulliparous women and to determine the effect of physical activity on ease of labour. METHODS: A prospective observational study, including 282 nulliparous women at 37-41 gestational weeks was conducted. Maternal demographic characteristics, obstetric history and Modified Grimby scale for evaluation of physical activity were noted. Patients were classified into spontaneous labour and induction group. Multiple logistic regression model was used to assess independent risk factors for type of delivery. RESULTS: Caesarean rate was increasing with higher educational status (p < 0.001). Maternal height, maternal and paternal age were higher, whereas dilatation on admission was lower in CS group (p < 0.05). Maternal age, weight gain and CS rate were higher in induction group (p < 0.05). Fetal distress as a cause of CS was detected higher in induction group (p < 0.05). Physical activity has no significant effect on mode of delivery (p > 0.05). Maternal height (p = 0.011), and cervical dilatation on admission (p = 0.004) were identified as predictor factors for CS. CONCLUSION: Cervical dilatation is the most important negative predictive factor for CS, whereas, moderate physical activity has no effect on mode of delivery. Fetal distress was the most frequent cause of CS in induction group.

Evaluation of risk factors in cesarean delivery among multiparous women with a history of vaginal delivery.

OBJECTIVE: To predict the risk of cesarean delivery (CS) for multiparous women who have undergone previous vaginal delivery. MATERIAL AND METHODS: A prospective observational study was performed, among multiparous pregnancies that were between 38 and 41 gestational weeks and had a singleton, vertex presentation fetus. Women's physical activity score, obstetric history, intrapartum and postpartum events were assessed. Multivariable logistic regression was used to explore risk factors associated with CS. RESULTS: Of the 245 total 83.7% had spontaneous labor and 16.3% were induced. Seventy-five percent of the induced women required CS, whereas only 19.5% of those with spontaneous labor required CS (p<0.001). The logistic regression analysis model included maternal weight gain, physical activity score, cervical dilatation, and fetal weight as the predictors of CS. We detected 7 (10%) maternal complications in women who underwent intrapartum CS. CONCLUSION: Labor induction is significantly associated with increased risk of cesarean delivery among previously vaginally delivered women and maternal weight gain, physical activity score, cervical dilatation, and fetal weight are most accurate parameters in the prediction of the risk of CS delivery. Intrapartum CS has an increased risk of maternal morbidity.
