RESUMO
OBJECTIVE: Bernard-Soulier syndrome (BSS) is one of the rare inherited platelet disorders that is characterized by macrothrombocytopenia and adhesion abnormality due to the absence or malfunctioning of the membrane GPIb-IX-V complex. There is no high-quality evidence on obstetric management of BSS owing to its rarity. Here we report an uncomplicated delivery of an adolescent with BSS and review the literature on the topic of BSS and pregnancy. METHODS: PUBMED, EMBASE, COCHRANE, and Google Scholar databases were searched up to April 2022 without language and year restriction using the terms "Bernard Soulier" and "Pregnancy". The primary objectives were to evaluate maternal and fetal outcomes. The secondary objectives were to analyze pregnancy complications, gestational age at delivery, mode of delivery, administered prophylaxis, treatment approaches, duration of postpartum hospitalization, and the postpartum requirement of blood and blood product. RESULTS: The patient was a 19-year-old and 39-week pregnant woman who was diagnosed with BSS at the age of 10 by flow cytometry and genetic analysis. Single donor platelet transfusions and oral tranexamic acid were administered as prophylaxis at the peripartum period. She was delivered by cesarean section due to failure of labor. The postpartum period was uneventful for both mother and neonate. In the literature review, postpartum hemorrhage (PPH) was found in 52.9% (27/51) of deliveries. Late PPH occurred more frequently than early PPH (35.3 and 31.4%, respectively). 49% (25/51) of pregnancies had severe thrombocytopenia, and antepartum hemorrhage was observed in 11.8% (6/51) of those. The platelet count was in close relation to antenatal complications. 64.7% (33/51) of the patients were delivered via cesarean section. PPH and late PPH were found to be more common in those who delivered vaginally compared to those who delivered by caesarean section. It was observed that PPH was less common in women who were given prophylaxis in the peripartum period. CONCLUSION: BSS is an inherited macro-thrombocytopathy that may cause adverse maternal and neonatal outcomes. The optimal mode and timing of delivery remain unclear. A multidisciplinary approach with prophylaxis at the peripartum period should be applied.

AIM: The aim of this study was to determine whether there was a difference in placental metabolite profiles between patients with fetal growth restriction (FGR) and healthy controls. METHODS: The study included 10 patients with FGR diagnosis with 14 healthy controls with both matched maternal age and body mass index. 1 H HR-MAS NMR spectroscopy data obtained from placental tissue samples of patients with FGR and healthy control group were analyzed with bioinformatics methods. The obtained results of metabolite levels were further validated with the internal standard (IS) quantification method. RESULTS: Principal component analysis (PCA) and the partial least squares discriminant analysis (PLS-DA) score plots obtained with the multivariate statistical analysis of preprocessed spectral data shows a separation between the samples from patients with FGR and healthy controls. Bioinformatics analysis results suggest that the placental levels of lactate, glutamine, glycerophosphocholine, phosphocholine, taurine, and myoinositol are increased in patients with FGR compared to the healthy controls. CONCLUSIONS: Placental metabolic dysfunctions are a common occurrence in FGR.

PURPOSE: To analyze endometrial metabolite profiles between patients with endometrial cancer and controls. METHODS: Seventeen (17) women with endometrium cancer and 18 controls were enrolled in this study. 1H HR-MAS (High Resolution-Magic Angle Spinning) NMR (Nuclear Magnetic Resonance) spectroscopy data obtained from endometrial tissue samples of patients with endometrial cancer and control group were analyzed with bioinformatics methods. RESULTS: Principal component analysis (PCA) and the partial least squares discriminant analysis (PLS-DA) score plots obtained with the multivariate statistical analysis of pre-processed spectral data shows a separation between the samples from patients with endometrial cancer and controls. Analysis results suggest that the levels of lactate, glucose, o-phosphoethanolamine, choline, glycerophosphocholine, phosphocholine, leucine, isoleucine, valine, glutamate, glutamine, n-acetyltyrosine, methionine, taurine, alanine, aspartate and phenylalanine are increased in patients with endometrial cancer compared to the controls. CONCLUSION: The metabolomics signature of patients with endometrial cancer is different from that of benign endometrial tissue.

The aim of this prospective study was to investigate whether there is a relationship between seminal plasma cadmium (Cd) and lead (Pb) levels and semen parameters in male partners of infertile couples. Two hundred fifty one (251) men recruited with no history of occupational exposure to toxic metals. After semen analysis, seminal Cd and Pb levels were measured using atomic absorption spectrometry. Cadmium levels in men with hypospermia was significantly higher than men with normal semen volume (p = .049). In contrast, there was no statistically significant difference in median seminal Pb levels between men with hypospermia and men with normal semen volume (p = .13). There was no statistically significant association between seminal plasma Cd and Pb levels sperm concentration, motility, morphology and total progressively motile sperm count. These findings suggest that environmental Cd exposure may contribute to low semen volume in male partners of infertile couples.IMPACT STATEMENTWhat is already known on this subject? Toxic metals may adversely affect both male and female reproductive system.What the results of this study add? Seminal plasma cadmium levels in men with hypospermia were statistically significantly higher than men with normal semen volume.What the implications are of these findings for clinical practice and/or further research? Patients should be informed about possible adverse effects of toxic metals.

PURPOSE: To determine the associations between pre-treatment self-reported stress level, salivary cortisol levels, and clinical pregnancy outcome in couples undergoing assisted reproductive technology treatment (ART). STUDY DESIGN: Seventy-five couples (150 patients) undergoing ART treatment were enrolled in this study. Psychological variables were assessed using the Perceived Stress Scale, Beck Anxiety Inventory, State-Trait Anxiety Inventory, and Beck Depression Inventory. Salivary cortisol levels were obtained from each couple prior to commencing gonadotropin treatment at several times (upon waking and at 15, 30, and 60 min after waking). RESULTS: There was no statistically significant association between the self-reported stress levels and the ART treatment outcome in couples. Women with a successful outcome after ART treatment had higher median salivary cortisol levels than women who had an unsuccessful result [24.7 (19.9-63.1) vs. 20.7 (10.4-30.4), respectively]. There was no statistically significant difference in the median salivary cortisol levels of men in relation to ART treatment outcome. Salivary cortisol levels of the couples were not correlated. CONCLUSIONS: Women who had higher median salivary cortisol levels in the pre-treatment period had a higher clinical pregnancy rate. This result suggests that moderately increased activity of the hypothalamic-pituitary-adrenal axis during ART treatment might be associated with successful conception.

We wanted to discuss our experiences in the approach to borderline ovarian tumors, which constitute a group different from epithelial ovarian tumors with respect to their biological structure in line with retrospective information gathered from our cases. A total of 25 patients operated on for the indication of adnexal masses diagnosed as borderline ovarian tumors based on frozen section results were included in our study. Patient age, tumor diameter, tumor markers and surgeries performed were discussed in the light of the literature. Statistical analyses were performed using the SPSS software. The patient mean age was 43.84±11.34 years. The mass was localized in the right (n=13), left (n=11) or both (n=1) adnexal regions. The mean tumor diameter was 12.9±5.84 cm. Histopathologic examination established the diagnosis of serous borderline (n=14 patients) and mucinous borderline (n=11) ovarian tumors. Although the results of our study are consistent with current literature data, a greater number of current studies should be performed on borderline ovarian tumors, which are defined as a class of tumors different from epithelial ovarian tumors.

BACKGROUND: The aim of this study was to examine the effect of thyroid-stimulating hormone (TSH) levels on intrauterine insemination (IUI) outcomes among euthyroid women. METHODS: A retrospective cohort study was conducted. A total of 302 women who started their first IUI cycle in our fertility center were included in this study. The patients were categorized into two groups based on their preconception TSH values: 0.38-2.49 mIU/Land 2.50-4.99 mIU/L. The clinical pregnancy rate was the main outcome parameter. As secondary parameters, we evaluated the differences in spontaneous abortion rate, live-birth delivery rate, and perinatal outcomes according to the preconception TSH threshold (< 2.5 and < 5.00 mIU/L). RESULTS: There was no significant difference between the two groups with respect to clinical pregnancy, miscarriage, and live-birth rates with an odds ratio of 1.67 (95% CI: 0.79-3.53), 1.08 (95% CI: 0.09-13.1), and 1.79 (95% CI: 0.77-4.2), respectively. In addition, there were no significant differences in perinatal outcomes (gestation at delivery, birth weight, and neonatal intensive care unit-administration rate) between the two groups. CONCLUSIONS: Our findings indicate that among euthyroid patients, preconception TSH values in the high-normal range (between 2.5 and 4.9 mIU/L) do not have a negative effect on IUI outcomes. TRIAL REGISTRATION: This study is retrospectively registered by Ethical Review Board at Inonu University in 19th December 2017; Ethics approval no is 2017-27-20.

OBJECTIVE: To demonstrate the outcome of intralesional management and show the safety of local treatment of cornual pregnancy. METHODS: Eight patients were treated with local methotrexate or potassium chloride injection. All patients underwent transvaginal ultrasound examination and were diagnosed by the criteria defined by Timor-Tritsch. In the case of fetal heart beat observation, potassium chloride was injected; and in the case of no heart beat detection, methotrexate was used. A follicle aspiration needle was inserted directly into the gestational sac under transvaginal guidance. RESULTS: Although it has been considered to be a risk factor, none of the patients in our study had previous ectopic pregnancy, history of infertility / in vitro fertilization, or cornual pregnancy. One of the patients had a medical history of abortion. In four cases, methotrexate was injected, and three patients received potassium chloride as a local treatment. None of the patients had any complication in the peri- or postoperative period. CONCLUSION: Using a local approach, the treatment agent can reach the area of the cornual pregnancy in high concentrations. Based on this case series, a local approach seems to be an effective and fertility-sparing method for treating unruptured cornual pregnancies.
RESUMO
In the current study, we aimed to investigate whether serum salusin α and ß levels are different in PCOS subjects. Fifty women with PCOS and 50 healthy, age- and body mass index matched controls were included to the prospective cross-sectional study. All subjects underwent venous blood drawing on the early follicular phase after an overnight fasting. Serum salusin α and ß levels were measured with EIA, and ELISA respectively. The relationships between serum salusin levels and anthropometric and metabolic parameters were also assessed. Plasma salusin α and ß levels were higher in women with PCOS compared to control group. Serum salusin α level correlated positively with salusin ß and fasting serum insulin levels. The serum salusin ß levels were correlated positively with HOMA-IR, TG, LDL-C, LH, FSH, and total testosterone levels. Our results indicate that salusins, newly identified regulators of hemodynamics and mitogenesis, are increased within the serum of women with PCOS.

AIM: To evaluate maternal and cord blood serum adropin concentrations in pregnant women with gestational diabetes mellitus (GDM). STUDY DESIGN: Twenty pregnant women with GDM and 20 gestational age-matched healthy pregnant women participated in the study. Maternal serum and cord blood adropin levels were assessed using an enzyme immunosorbent assay, at the time of birth. The relation of maternal serum and cord blood adropin levels with metabolic parameters were also assessed. RESULTS: The mean maternal and cord serum adropin in the GDM group were significantly lower than those of the control women (P=0.01 and P<0.001, respectively). Maternal serum adropin levels did not correlate with either fetal serum adropin levels or maternal metabolic values. CONCLUSION: The data suggest that low adropin levels may contribute to the underlying pathogenesis of GDM.

AIM: The aim of this study was to analyze whether urocortin-1 concentration in midtrimester amniotic fluid could serve as an indicative marker of preterm labor. MATERIAL AND METHODS: A retrospective cohort study was conducted. Urocortin-1 concentrations in midtrimester amniotic fluid were measured in 22 pregnant women with preterm deliveries and 45 women who delivered at term using enzyme-linked immunosorbent assay. RESULTS: The median amniotic fluid urocortin-1 concentration was significantly lower in the women with preterm birth (40.06 pg/mL; range, 13.77-67.58 pg/mL) than in the women who gave birth at term (49.56 pg/mL; range, 26.25-175.9 pg/mL; P = 0.022). The result of receiver-operator curve analysis indicates that an amniotic fluid urocortin-1 concentration ≤ 57.88 pg/mL had an area under the curve of 0.673 (95% confidence interval, 0.55-0.78; P = 0.01) with a sensitivity of 81.8%, specificity of 40.0%, positive predictive value of 40%, and a negative predictive value of 82% in identifying which of the patients subsequently delivered prematurely. CONCLUSIONS: These results suggest that low urocortin-1 concentration in midtrimester amniotic fluid could be used as an indicative marker of preterm birth.

OBJECTIVES: To investigate the association between selected sexually transmitted infections (STIs) and the later occurrence of ectopic pregnancy. METHODS: A total of 125 women with ectopic pregnancy and 125 pregnant controls were recruited between January 2003 and February 2005 at Dr. Zekai Tahir Burak Women's Health Education and Research Hospital, in Ankara, Turkey. Enzyme-linked immunosorbent assay was used to determine the prevalence of serum antibodies to Chlamydia (C.) trachomatis and to Herpes simplex virus (HSV)-2 IgG and, indirect immunofluorescence test was used to determine the prevalence of serum antibodies to Mycoplasma (M.) hominis and Ureaplasma (U.) urealyticum. RESULTS: The prevalence of C. trachomatis Ig G antibody in women with ectopic pregnancy (31/125; 25%) was significantly higher than in controls (12/125; 9.6%) (crude Odds Ratio [OR]: 3.1, 95% confidence interval [CI]: 1.51-6.38; p = 0.001). However, there was no significant association between C. trachomatis IgM; M. hominis IgG, IgM; U. urealyticum IgG, IGM; and HSV-2 IgG, and ectopic pregnancy. CONCLUSIONS: Previous chlamydial infection plays an important role in the aetiology of ectopic pregnancy. There was no association between M. hominis, U. urealyticum and HSV-2 infections, and ectopic pregnancy.

We present an 18-year-old pregnant woman who was referred to our emergency clinic as a case of acute hepatic failure and hepatic encephalopathy. Laboratory tests showed abnormal liver function tests and serological workup was consistent with acute hepatitis A infection. Ultrasonography revealed a single live fetus with fetal biometry compatible with 18 gestational weeks. The patient underwent a highly urgent liver transplantation using a right lobe graft from her husband. Histological examination of the explanted liver showed acute, lymphocyte-rich, diffuse necrotizing hepatitis, consistent with acute necrotizing hepatitis A. After the operation her allograft function gradually recovered. Her follow-up obstetrics ultrasound revealed a male fetus with severely decreased amniotic fluid. The patient was informed about the poor prognosis of her pregnancy and the pregnancy was terminated by vaginal misoprostol induction. She has maintained a good general condition and liver function for 4 months postoperatively, up to the present time.

AIM: The aim of the present study was to evaluate the role of oxidative stress and DNA damage in preeclampsia and intrauterine growth restriction (IUGR). MATERIAL AND METHODS: Twenty-four patients with preeclampsia, 20 patients with IUGR fetus and 37 healthy pregnant women were enrolled in the study. The total oxidant status (TOS) and antioxidant status (TAS) of plasma were measured using a novel automated colorimetric measurement method. Sister chromatid exchange (SCE) and micronuclei analysis were performed on peripheral blood lymphocytes of cases and controls. RESULTS: Women whose pregnancies were complicated with preeclampsia and IUGR had elevated levels of TOS and TAS when compared with healthy pregnant women (median TOS values: 9.73, 10.6 and 8.06, P = 0.001; median TAS values: 1. 77, 1.54 and 1.44, P < 0.001, respectively). The frequencies of SCE were only found to be increased in women with IUGR fetus compared with healthy pregnant women (8.81 vs 7.5, respectively, P = 0.02). Multivariable linear regression analysis for both TOS and TAS showed a significant relation between these variables and uric acid. CONCLUSION: Increased oxidative stress and antioxidative defense mechanisms may contribute to disease processes both in preeclampsia and IUGR.

OBJECTIVE: To determine whether concentrations of oxidative stress markers of follicular fluid and serum are different in GnRH agonist protocol from GnRH antagonist protocol. MATERIAL AND METHOD: This was a cross-sectional study. Eighty-four women undergoing controlled ovarian stimulation with either GnRH agonist (n = 39) or GnRH antagonist protocols (n = 45) for IVF/ICSI treatment were assigned by a physician. Blood was obtained at the time of oocyte retrieval, and follicular fluid (FF) from the mature follicles of each ovary was centrifuged and frozen until analysis. Malondialdehyde (MDA), nitric oxide (NO), protein carbonyl (PC), hydroxyl proline (OH-P), sodium oxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (GSH-Px), adenosine deaminase (ADA) and xanthine oxidase (XO) were assessed in the serum and follicular fluid of each participants. RESULTS: The mean serum concentrations of GSH-Px, GSH and MDA were lower in the GnRH antagonist group compared to GnRH agonist group, but mean serum SOD was higher in the GnRH antagonist group. The mean follicular SOD, ADA and NO were higher in GnRH antagonist group than GnRH agonist group. The IVF/ICSI outcomes were similar in both groups. CONCLUSION(S): GnRH antagonist protocol is associated with increased oxidative stress. The relation of GnRH analogues with oxidative stress and its implication in follicular growth needs to be addressed in further studies.

PURPOSE: The purpose of this study was to evaluate the cardiac and cerebral oxidative stress in the offspings of pregnant rats treated with oxytocin antagonist atosiban. METHODS: Experimentally naive, adult female Wistar-albino rats (200-250 g) were mated with adult male rats for copulation. After confirming pregnancy, eight gravid rats were then randomly assigned into two equal groups. The animals were treated from days 15 to 20 of gestation. One group acted as a control group, and received intraperitoneal (i.p.) injections of saline in a daily dose volume of 6 mg/kg/day. The second group received 6 mg/kg/day i.p. atosiban. On day 21 of gestation, pups were delivered by cesarean. The heart and brain tissues of the newborn rats were dissected and sent for the measurement of total oxidant status, total antioxitant status and oxidative stress index. RESULTS: There was no significant difference in birthweight or in the number of pups between two groups. Newborns from atosiban-treated mothers showed significantly increased oxidative stress in the plasma and heart tissue than that of controls which was confirmed by histological examination (P < 0.05). Oxidative stress parameters and histopathological results of the brain tissues of newborns were similar between two groups (P > 0.05). CONCLUSION: Oxytocin receptor blockage for the treatment of premature delivery may be associated with increased fetal morbidity and mortality secondary to the elevated oxidative stress in the heart of the newborns.

PURPOSE: The current study investigated the potential therapeutic efficiency of atosiban, an oxytocin receptor antagonist, in an experimental endometriosis model. METHODS: Endometriosis was surgically induced in 35 female rats during estrus. Four weeks after this procedure, relaparotomy was performed. The viability and dimensions of the endometriosis foci were recorded. Rats were then randomly divided into three groups. In the first group (n = 8), a daily dose of 0.2 ml 0.9 % NaCl was injected intraperitoneally (i.p.) (control cases). In the second and third groups (n = 8 and n = 8), 0.5 mg/kg/day i.p. atosiban and 1 mg/day i.p. diltiazem were given, respectively. At the end of the treatment, laparotomy was performed, and the dimensions of the endometriosis foci were recorded. The endometrial implants were processed for histological and immunohistochemical studies. The volumes of endometriotic implants were measured, and immunohistochemical analyses were performed, and compared between the groups. RESULTS: After the treatment with atosiban, volumes of endometriotic implants decreased significantly. Proliferating cell nuclear antigen expression levels were significantly reduced in the atosiban and diltiazem groups compared with the control group. CONCLUSIONS: In a rat endometriosis model, atosiban, an agent used for the first time for the medical treatment of endometriosis, has shown significant therapeutic efficiency.

Introduction This study aims to reveal the maternal and neonatal adverse outcomes, associated with adolescent pregnancies in our country, to investigate whether the 20 to 21-year-age group, which is very close to the adolescent age, is similar to the adolescent age group in terms of adverse outcomes, and so to contribute to the definition of the upper limit in adolescent age for pregnancy. Methods Four hundred and twenty-four pregnant women under the 20-year-age, 450 pregnant women at 20 to 21-year-age, and 450 pregnant women between 22 and 25-year-age were included in this retrospective study. Maternal demographic features, clinical characteristics, obstetric complications, maternal outcomes, neonatal complications, and neonatal outcomes were collected from the medical records of the participants. Results There were statistically significant differences between under 20-year-age and 22 to 25-year-age, regarding gestational age at birth, maternal duration of hospitalization after delivery, mode of delivery, preterm delivery rate, very low birth weight, and low birth weight, first minute Apgar score, the presence of transient tachypnea of the newborn. Conclusion The upper age limit for the adolescent age, which is considered risky in terms of maternal and neonatal adverse outcomes, was found to be compatible with the upper age limit, which is 19 years, defined by World Health Organization.
RESUMO
The aim of the present study was to investigate the expression patterns of prokineticins (PROK) and prokineticin receptors (PROKR) in the endometrium of women with recurrent implantation failure (RIF). Fifteen (15) women with RIF and 15 fertile controls were enrolled in this study. Endometrial samples were taken from study participants with an endometrial biopsy cannula during the implantation window. Real time polymerase chain reaction and immunohistochemistry were used to determine PROK/PROKR mRNA expression and protein localization, respectively. PROK1 mRNA levels were 6.09 times higher compared to endometrial samples obtained from women with RIF than in samples obtained from fertile controls, whereas PROKR1 mRNA levels were 2.46 times lower in endometrial samples obtained from women with RIF than in samples from fertile controls. In addition, decreased PROKR1 was supported by immunohistochemistry analysis at protein level. There was no statistically significant difference between women with RIF and fertile controls regarding PROK2 and PROKR2 levels. Altered expression of the PROK1/PROKR1 system could be one of the numerous abnormalities in the endometrium of women with RIF.
