Abstract
PURPOSE To demonstrate and understand the association of HPV infection and biofilm formation. METHODS The study consisted of cervicovaginal samples of 72 women who were evaluated at the colposcopy unit. Papanicolaou staining was used for cytological examination while "Crystal Violet Binding" assay was performed to detect biofilm formation. RESULTS HPV-DNA was positive in 55.5% (n = 40) of the patients. The biofilm formation rate was statistically significantly higher in the HPV-positive women (45%) compared to HPV-negative women (21.9%) (P < 0.05). There was a statistically significant relationship between the presence of single HPV and "high-risk HPV" types and biofilm formation (P < 0.05). Biofilm formation was found in 80% of women with abnormal smear demonstrating atypical epithelial cells (P < 0.05). CONCLUSION Biofilm formation is more frequent at the cervicovaginal microbiota of patients with HPV infection. This finding is especially important in cases with atypical epithelial cells at their cervicovaginal smears.

Abstract
Down Syndrome is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. Metabolomics is identification and quantification of small-molecule metabolites (molecular weight <1000 Da) in tissues, cells and physiological fluids within a certain period time. Metabolites are intermediate products of various types of biochemical reactions that participate in bonding metabolic pathways. In this study, metabolites such as 2-Hydroxybutyric acid, 3-Hydroxybutyric acid, β-Hydroxyisovaleric acid, Uracil, Glutamic acid, Maltose and Melezitose were chosen as the possible determinants/markers for the prenatal screening of Down Syndrome. Quantitative analysis of the metabolites conducted by GCMS method using 5 % phenyl / 95 % dimethylpolysiloxane (30 m ×0.25 mm, 0.25 μm film thickness) capillary column. The oven temperature was held constant at 60 °C for 1 min and ramped at 10 °C /min to 200 °C then ramped at 30 °C/min to 320 °C and hold for 6 min before cool-down, as helium mobile phase and flow rate of 2.8 mL/min and adding Myristic acid-d27 as an internal standard. Our method was validated by parameters of system suitability, stability, linearity, sensitivity, accuracy, precision, selectivity, robustness and ruggedness. The developed and validated method was applied to plasma samples taken from pregnant women with Down Syndrome (study group) and euploid fetuses (healthy group). The levels of these seven metabolites are statistically different (p < 0.05 for all) between the groups. It can be concluded that these relevant metabolites might be used for the prenatal screening of Down Syndrome.

Abstract
OBJECTIVE To evaluate the association between bacterial vaginosis (BV) and autoimmune antibody positivity. METHOD We evaluated Papanicolaou-stained cervicovaginal smears of 210 patients with poor obstetric history who were admitted to a special preconception counselling programme. Cytological specimens with various types of microorganisms except for BV, epithelial cell abnormalities and other non-neoplastic findings, including inflammation were excluded from the cohort in addition to patients with autoimmune and chronic inflammatory diseases. The remaining study population (n = 121) was divided into two groups of patients with autoimmune antibody positivity (study group, n = 80) and patients without antibody positivity (control group, n = 41). RESULTS The rate of BV was demonstrated to be 13.8% and 2.4% in the study and control groups respectively (P = .042). We also demonstrated that the anti-nuclear antibody was positive in 58.3% of the cases with BV. CONCLUSION BV was found more frequently in patients with autoimmune antibody positivity to a statistically significant degree.

Abstract
AIM To determine a cut-off value for systemic immune-inflammation index (SII)(neutrophil × platelet /lymphocyte) in the prediction of adverse neonatal outcomes in preterm premature rupture of the membranes (PPROM). METHODS This retrospective cohort study was conducted among singleton pregnancies with PPROM. Cases were divided into two main groups: Group 1) PPROM diagnosed at 24th-28th weeks of gestation and Group 2) PPROM diagnosed at >28th-34th weeks of gestation. Thereafter, main study groups were divided into two subgroups: Subgroup A: pregnancies with favorable neonatal outcomes and Subgroup B: pregnancies with composite adverse neonatal outcomes. Subgroups were compared in terms of demographic features, clinical characteristics, laboratory test results and SII values. Furthermore, cut-off values of SII for the prediction of composite adverse neonatal outcomes were determined for two main groups. A Mann-Whitney U test was conducted to compare the median values and the chi-square test was used to compare categorical variables among the groups. Receiver operating characteristic (ROC) curves were used to assess the performance of SII value in predicting composite adverse neonatal outcomes. RESULTS Significant differences were observed for median platelet and SII values between the subgroups (P < 0.001 for both in group 1 and P = 0.002 and P = 0.005, respectively, in group 2). Cut-off values of 1695.14 109 /L (83.3% sensitivity, 85.7% specificity) and 1430.90 × 109 /L (71.4% sensitivity, 75.7% specificity) for composite adverse neonatal outcomes were determined, respectively in group 1 and 2 according to the ROC curve analysis. CONCLUSION SII may be used as an additional indicator for the prediction of adverse neonatal outcomes in PPROM.

Abstract
OBJECTIVE To share our experience in diagnosis of congenital central nervous system (CNS) abnormalities by fetal magnetic resonance imaging (MRI). STUDY DESIGN This study consisted of 110 pregnancies. Neurosonography (NS) findings were compared with MRI results. Anomalies were categorized into 10 groups: 1) Corpus callosum (CC) and cavum septum pellucidum (CSP) anomalies, 2) Neural tube defects (NTD), 3) Posterior fossa anomalies (PFA), 4) Primary ventriculomegaly (PVM), 5) Microcephaly, 6) Macrocephaly, 7) Periventricular leukomalacia (PVL), 8) Craniosynostosis, 9) Intracranial hemorrhage (ICH) and 10) Lumbosacral teratoma. Demographic features, clinical characteristics and perinatal outcomes of the study subjects were evaluated. RESULTS Gestational weeks for NS and for MRI were 25.5 and 26.5 weeks, respectively. Fourteen (12.7%) pregnancies were terminated. PVM (n = 36, 32.7%), CC and CSP anomalies (n = 29, 26.3%), PFA (n = 11, 10%) and NTD (n = 11, 10%) were the most common fetal MRI indications. There were no statistically significant differences between the accuracy of fetal NS and fetal MRI for CC and CSP anomalies, NTDs, PFA and PVM (p = 0.09, 0.43, 0.45 and 0.23, respectively). However, fetal MRI was more accurate for the detection of normal anatomic findings in cases with suspected microcephaly, macrocephaly and craniosynostosis in NS when pooled together (p = 0.007). Furthermore, MRI also seemed to be advantageous in CC & CSP anomalies though it was not validated by statistical measures. No statistically significant difference was found for diagnostic performance of NS and MRI according to gestational week (p = 0.27). CONCLUSION Fetal MRI in addition to NS may improve diagnostic accuracy in pregnancies with congenital CNS abnormalities.

Abstract
Objective: We investigated the importance of prophylactic administration of low-dose low-molecular-weight heparin (LMWH) in women with risk factors associated with placental inflammation.Materials and methods: This retrospective cohort study included 300 pregnant women with a singleton pregnancy (30 primigravidas and 270 multigravidas) who received prophylactic low-dose LMWH to prevent placental inflammation. Based on maternal risk factors, patients were categorized into 3 groups as follows: Group 1: Patients with metabolic risk factors for placental inflammation (n = 205), Group 2: Patients with immunological risk factors for placental inflammation (n = 42), Group 3: Patients with metabolic and immunological risk factors for placental inflammation (n = 53). Obstetric histories, demographic features, clinical characteristics, and present pregnancy outcomes were compared between groups. Live birth rates, composite adverse obstetric outcomes, and the Beksac obstetric index were compared between present and previous pregnancies in multigravidas.Results: Pregnancy outcomes were significantly better in the present pregnancy than in previous pregnancies. A significant increase was observed in live birth rates (33.4% vs. 69.9%, 27.5% vs. 60.5%, and 30.1% vs. 69.4% in groups 1, 2, and 3, respectively) and in the Beksac obstetric index (0.32 vs. 0.43, 0.33 vs. 0.47, and 0.38 vs. 0.57 in groups 1, 2, and 3 respectively) (p < .001 for all). A significant decrease in composite adverse pregnancy outcome rates was observed during the present pregnancy (23.5% vs. 100%, 28.9% vs. 100%, and 24.5% vs. 100% in groups 1, 2, and 3, respectively) (p < .001 for all). Live birth and composite adverse obstetric outcome rates were 70% and 33.3%, respectively in primigravidas.Conclusion: Low-dose low-molecular-weight heparin prophylaxis is useful to prevent metabolic and immunological disorders causing placental inflammation, which is the most likely pathophysiological mechanism contributing to various obstetrical complications.

Abstract
The aim of this study was to demonstrate the altered metabolic infrastructure of pregnant women with methylenetetrahydrofolate reductase (MTHFR) polymorphisms at first trimester and during delivery. Eight singleton pregnant women with MTHFR polymorphisms were compared with 10 normal pregnant women. Maternal blood samples were obtained twice during their pregnancy period (between the 11th and 14th gestational weeks and during delivery). Metabolomic analysis was performed using GC-MS. The GC-MS based metabolomic profile helped identify 95 metabolites in the plasma samples. In the MTHFR group, the levels of 1-monohexadecanoylglycerol, pyrophosphate, benzoin, and linoleic acid significantly decreased (P ˂ 0.05 for all), whereas the levels of glyceric acid, l-tryptophan, l-alanine, l-proline, norvaline, l-threonine, and myo-inositol significantly increased (P ˂ 0.01 for the first two metabolites, P ˂ 0.05 for the others) at 11-14 gestational weeks. Conversely, the levels of benzoin, 1-monohexadecanoylglycerol, pyruvic acid, l-proline, phosphoric acid, epsilon-caprolactam, and pipecolic acid significantly decreased in the MTHFR group, whereas metabolites such as hexadecanoic acid and 2-hydroxybutyric acid increased significantly in the study group during delivery. An impaired energy metabolism pathway, vitamin B complex disorders, tendency for metabolic acidosis (oxidative stress), and the need for cell/tissue support seem prevalent in pregnancies with MTHFR polymorphisms.

Abstract
AIM To investigate the relationship of cholelithiasis and urolithiasis with Methylenetetrehydrofolate Reductase (MTHFR) polymorphism(s) in patients with poor obstetric history to search whether they are risk factors for adverse pregnancy outcome. MATERIALS AND METHOD This study is consisted of 94 patients with poor obstetric history. Patients were evaluated in terms of the presence of cholelithiasis and urolithiasis in association with MTHFR polymorphism(s). Additional laboratory tests including homocysteine measurements were also performed. ROC analysis for assessing the performance of blood homocysteine level in predicting the presence of cholelithiasis and urolithiasis were also performed. RESULTS Patients were divided into three groups such as cholelithiasis group (n = 9, 9.6%), urolithiasis group (n = 18, 19.1%) and control group (n = 67, 71.3%). Groups did not differ in term of age and Beksac obstetrics index (BOI) which is "[living child+(π/10)]/gravidity." The rate of the presence of MTHFR polymorphisms were 88.9% (8/9), 88.9% (16/18) and 43.3% (29/67) in cholelithiasis, urolithiasis and control groups respectively. Median homocysteine levels were found to be 13.1, 11.6 and 7.2 micromol/lt for the groups respectively. Statistically significant differences were found for MTHFR polymorphism rates and homocysteine levels (<0.001 for both). According to ROC analysis, 10.9 mcmol/L (88.9% sensitivity, 89.6% specificity) and 9.25 mcmol/L (83.3% sensitivity, 73.1% specificity) were determined to be cutoff values of homocysteine for cholelithiasis and urolithiasis respectively. CONCLUSION More frequent MTHFR polymorphisms are observed in women with a clinical history of gall or renal stones. Thus, screening of these patients may be benefical for the approprate management of their subsequent pregnancies.

Abstract
OBJECTIVE To investigate the reasons for decision-making and concerns of patients in the field of prenatal screening, invasive prenatal diagnostic testing (IPDT), and termination of pregnancy (TOP). STUDY DESIGN This questionnaire-based study consisted of 107 pregnant women who were referred for prenatal screening to the Hacettepe University Hospital. The questionnaire given to patients was prepared from scratch since there is no standard set of questions measuring patients' feelings and concerns regarding prenatal screening/diagnosis, IPDT, and TOP. RESULTS Our questionnaire results showed that it is possible to classify decision-making factors into 6 groups: psychological, social, fear, religious/faith, support, and trust. The majority of patients were undecided (48.6%) about IPDT if prenatal screening test results were risky. Only 23.4% of patients were willing to accept IPDT. On the other hand, 55.1% of patients were not willing to undergo TOP if the fetal karyotyping results were abnormal. Religious factors seem to be important in refusing IPDT and TOP. CONCLUSION Physicians should re-evaluate their practice in the field of prenatal screening and diagnosis in light of the high refusal rates of IPDT and TOP. Understanding factors influencing women's decision-making processes provides insight for service providers to help women at high risk of having foetal anomalies to make better-informed choices.

Abstract
Objective: To introduce the effect of a single course of betamethasone for pregnant women at risk of preterm delivery (PTD).Materials and methods: In this study, a single course of 12 mg Bethamethasone was administered twice in 24 h (between 24-34 gestational weeks) for antenatal corticosteroid prophylaxis. Four hundred ninety-three neonates fulfilled the inclusion criteria and they were categorized (259 singletons, 192 twins and 42 triplets who met the inclusion criteria) into two groups according to the utilization of antenatal corticosteroid as control (n = 202) and study (n = 291) groups. We used respiratory distress syndrome (RDS), congenital pneumonia, intraventricular hemorrhage (IVH), neonatal sepsis, and bronchopulmonary dysplasia (BPD) as primary outcomes for the evaluation of neonatal morbidity.Results: Study and control groups were similar in terms of clinical characteristics. RDS, congenital pneumonia, neonatal sepsis, and BPD rates were significantly higher in the study group (betamethasone) (p = .05, p = .007, 0.003, and 0.004, respectively) between 24-34 gestational weeks (when the neonates of multiple pregnancies were excluded from the analysis, we have demonstrated that congenital pneumonia (p = .033) and neonatal sepsis (p = .030) were still significantly higher in the betamethasone group). The neonates of 24-28 gestational weeks were compared separately and we demonstrated that RDS (p = .012), congenital pneumonia (p = .022), IVH (p = .044), neonatal sepsis (p = .023), and BPD (0.001) were also more frequent in the study group. When the 28-32 gestational week data were compared, IVH (p = .020) and neonatal sepsis (p = .017) were more frequent in the single course betamethasone users. However, we could not demonstrate a significant difference between the control and study groups between 32-34 gestational weeks in terms of the primary neonatal outcomes used in this study.Conclusion: Single course antenatal betamethasone administration may be ineffective on the respiratory complications of preterm and very preterm infants while it may be unfavorable for extremely preterm infants.What is new about the paper, what could add to the current knowledge: Pregnant women at risk for preterm labor must be under intensive antenatal care programs, and if possible, necessary precautions must be undertaken to prevent fetal hypoxia together with etiology specific treatments. This approach might contribute to better perinatal outcomes than just administering antenatal corticosteroid therapy.

Abstract
Aim
To evaluate thrombocytopenic pregnancies including gestational thrombocytopenia (GT), idiopathic thrombocytopenic purpura (ITP), and hypertensive disorders of pregnancy (HDP).
Materials and Methods
We evaluated the pregnancy outcomes and laboratory findings of 385 patients diagnosed with GT, ITP, or HDP whose thrombocyte levels were < 150 000/µL.
Results
GT, ITP, and HDP were the final diagnoses in 315 (81.8%), 35 (9.1%), and 35 (9.1%) cases, respectively. Patients diagnosed during the 1st trimester and diagnosed with ITP had significantly lower minimal platelet counts during the antenatal period and prior to delivery (p < 0.001; p < 0.001; p < 0.001; p < 0.001). Transfusion of any kind of blood product was given in 9.9% (n = 38) of all cases. Twelve patients had methylprednisolone and/or intravenous immunoglobulin treatments during the antenatal period. All patients who had undergone medical treatment were also found to have ITP. Four out of 385 patients underwent hysterectomy post partum due to refractory hemorrhage. Analysis of newborn platelet levels showed no statistical differences between any of the groups. Despite the lack of statistical significance, the rate of thrombocytopenia in newborns was 50% in patients with severe thrombocytopenia, while rates were 25.6 and 18.1% in patients with moderate and mild thrombocytopenia, respectively.
Conclusion
Thrombocytopenic pregnancies must be carefully evaluated with regard to the severity of thrombocytopenia, gestational period at initial diagnosis, and etiology. In particular, patients with ITP must be evaluated carefully as these patients are more likely to require transfusions and have platelet counts < 50 × 10

Abstract
The aim of this study is to evaluate the significance of renal pelvis aspiration (RPA) in the management of antenatal hydronephrosis (AHN). This study enrolled 15 AHN cases (one twin pregnancy) that necessitated RPA for AHN. Chromosomal abnormalities, gene disorders, and additional life-threatening congenital abnormalities were eliminated prior to intrauterine interventions. Urine analysis were performed for the evaluation of renal function. Normal renal function was observed in six neonates/infants (40%) (group 1), whereas impaired renal function and various type of urinary system anomalies were observed in 9 neonates/infants (60%) (group 2) during the short-term and longitudinal follow-up periods. There were statistically significant differences in the oligohydroamniosis rate, mean fetal urine sodium value, mean fetal urine β2-microglobulin, mean gestational week at birth, and mean birthweight values between the groups (P = 0.007, P < 0.001, P = 0.035, P < 0.001, and P = 0.001, respectively). Renal pelvis aspiration and urine analysis were substantial for the management of AHN in necessary cases. β2-microglobulin and sodium are clinically useful markers to detect the presence of severe renal damage due to obstructive uropathy and thus, important adjuvants in the proper selection of fetuses for further antenatal interventions.

Abstract
OBJECTIVE To demonstrate the effect of preconceptional complement levels on perinatal outcomes of pregnancies with autoimmune disorders. METHODS Pregnant women with autoimmune disorders (autoimmune disease and/or autoimmune antibody positivity) who were screened for complement levels (C3 and C4) prior to their pregnancies were enrolled in a special antenatal care program. These patients were administered low-dose low-molecular-weight heparin (enoxaparine, 1 × 2000 Anti-XA IU/0.2 mL/day), low-dose salysilic acid (100 mg/day) and low-dose corticosteroid (methylprednisolone, 1 × 4 mg/day orally) as soon as their pregnancies were confirmed according to the institutional protocol. We have compared hypo- and normocomplement pregnancies with autoimmune disorders in terms of their obstetric and perinatal outcomes. We have also used Beksac Obstetric Index (BOI) which is "[living child + (π/10)]/gravidity" for the comparison of their previous obstetric histories. RESULTS Obstetric and neonatal outcomes showed no significant difference between hypocomplement patients (n= 38) and control group (n= 157) (p> 0.05). "Composite obstetric and perinatal adverse outcome" rates were 26.2% and 27.3% in study and control groups, respectively (p> 0.05). BOI was significantly lower in hypocomplement patients (p: 0.002). Then, we have classified hypocomplement patients into 3 subgroups according to the type of complement (C3, C4 or both). Comparison inbetween these groups revealed no statistical significance in any of the analyzed parameters (p> 0.05). CONCLUSION Low complement levels in pregnant women with autoimmune disorders may be associated with gestational problems and poor obstetric history. Immunomodulatory treatment modalities such as ours may be beneficial for improving the obstetric and neonatal outcomes.

Abstract
BACKGROUND To evaluate obstetrical and perinatal outcomes of pregnancies with ankylosing spondylitis (AS). METHODS This was a retrospective study evaluating obstetric outcomes of 52 patients with AS who were followed up at our institution between 2006 and 2019. Patients were classified as having disease greater than or less than 5 years, and according to disease-related medical treatment during pregnancy, as drug free, single medication or multiple medication. RESULTS Overall rates of preterm delivery, intrauterine growth retardation and preeclampsia were 17.3%, 13.4% and 7.7%, respectively. Thirty-three of the patients were followed up without any medication, while 19 patients used drugs during pregnancy. Seven patients used a single drug and 12 patients had multiple drugs. There was no significant difference in terms of obstetrical and neonatal outcomes. However, a higher rate of neonatal intensive care unit (NICU) admission was observed in the group using medication for AS, despite a lack of statistical significance (31.5% vs 15%, P = .162). On the other hand, patients having disease more than 5 years had higher rates of Apgar scores less than <7 and admission to the NICU despite a lack of statistical significance (4% vs 7.4% and 16% vs 26%; P = .267 and P = .297, respectively). CONCLUSION In conclusion, pregnancies of patients with AS must be considered as high risk due to increased rates of adverse outcomes such as preterm delivery, intrauterine growth retardation or preeclampsia.

Abstract
Objective: This study aimed to describe the impact on achieving spontaneous pregnancy of
treating patients with at least one failed in-vitro fertilization (IVF)
cycle for autoimmune disorders, hereditary thrombophilia, and methylation
disorders. Methods: Fifty-three patients who met the enrollment criteria seen between January
2007 and October 2017 were included in this retrospective cohort study. The
patients were retrospectively assessed for the presence of hereditary
thrombophilia, methylenetetrahydrofolate reductase (MTHFR) polymorphisms,
serum vitamin B12/folate/homocysteine levels, and autoimmune antibody
positivity. The required data were extracted from the institutional patient
database. Statistical analyses were performed on Statistical Package for the
Social Sciences (SPSS.22®). The Kolmogorov-Smirnov test
was used to evaluate the distribution of the data, and since the data did
not following a normal distribution, proportions and median
(minimum-maximum) values were used. Results: The 53 patients included in the study had singleton pregnancies. The
distribution of autoantibodies was as follows: thyroid peroxidase (n=17);
antithyroglobulin (n=11); double-stranded DNA (n=4); antinuclear (n=8);
anti-smooth muscle (n=1); and anticardiolipin IgG and IgM (n=1). Autoimmune
diseases included Hashimoto's thyroiditis (n=23); SLE (n=7); Behcet's
disease (n=1); Sjogren's syndrome (n=1); ulcerative colitis (n=1); and
anti-phospholipid antibody syndrome (n=1). Ten patients had heterozygous
Factor V Leiden thrombophilia; two had homozygous Factor 5 Leiden
thrombophilia; and three had the prothrombin 20210A heterozygous mutation.
Twenty-eight patients were positive for autoantibodies and hereditary
thrombophilia and/or MTHFR polymorphisms. Conclusions: Evaluation and management of hereditary thrombophilia, MTHFR gene
polymorphisms, and/or autoimmune conditions may be beneficial for patients
with unexplained infertility.

Abstract
BACKGROUND Several methods have been applied to detect death cells in tissue, cell culture, and fluid samples. We aimed to compare the cytological and immunocytochemical methods for detecting apoptotic cells in cervicovaginal smears. METHODS Cervicovaginal smears were taken from 102 women for various gynecological complaints. The slides were stained using the Papanicolaou (Pap)-staining method for cytological evaluation. Cleaved caspase 3 (CC3) antibody was used to detect apoptosis by immunocytochemically, and H-Score was used for the evaluation. In Pap-stained smears, apoptosis was detected and evaluated using our new scoring system by the examination of morphological changes of epithelial cells such as apoptotic bodies, blebbing, karyopyknosis, karyorrhexis, and karyolysis. We used Kappa analysis to understand whether there is an agreement between cytological and immunocytochemical methods for detecting apoptotic cells. RESULTS Cytological and immunocytochemical methods showed similarities at a moderate level (κ = 0.482, P < .001). The cytological and immunocytochemical scores were also similar to each other at a fair level (κ = 0.373, P < .001). Pap smears had a sensitivity of 64.40% (95% CI: 50.12-76.01), specificity of 86.04% (95% CI: 72.65-94.83), positive likelihood ratio of 4.62, negative likelihood ratio of 0.41, positive predictive value of 86.36%, negative predictive value of 63.79%, and overall probability of 73.53% compared to immunocytochemical staining. CONCLUSIONS Our results demonstrate that Pap smear and cytological scores alone were not good enough to identify apoptosis compared to the immunocytochemical studies. However, because of its high specificity, it may still be an adequate method to detect apoptotic cells.

Abstract
BACKGROUND AND OBJECTIVES Our aim is to identify uropathogens that cause urinary tract infections (UTIs) that necessitate hospitalization, and analyze outcomes of gestational UTIs. METHODS This study consisted of 30 pregnant women who necessitate hospitalization because of UTI (7.8% of gestational UTIs during the same period of time). UTI that necessitates hospitalization is defined as clinical complaints, urination problems, urine analysis and culture positivity, fever and uterine discomfort. Patients with at least two positive cultures (≥ 100,000 cfu/ml) were included to this study. Antimicrobial susceptibility tests were obtained in all cases in order to determine antimicrobial resistance and to choose the ideal antibiotics for treatment. RESULTS In our study, we have found that Escherichia coli is the most common microorganism (56.7%). Enterococcus faecalis (13.3%) and Klebsiella pneumonia (10%) were other frequently observed microorganisms. In this series, mean gestational week at birth was 35 weeks 5 days (range 23-40 weeks). Mean birthweight was 2,656 g (range 500-3,700 g). Twenty-three cases (76.7%) were hospitalized before 37th gestational week and preterm delivery rate was 56.3%. Maternal risk factors and coexisting diseases were detected in 11 (36.7%) patients as follows: diabetes mellitus in 4, thrombophilia in 3, thyroid disorders in 3 and hydroureteronephrosis in 1 case. Cesarean section rate was 65.2%. CONCLUSIONS Knowing uropathogens of patient population is beneficial in the management of patients and better planning of future medical treatments. Preterm labor seems to be an important complication in pregnancies with UTIs going together with fever and urination problems.

Abstract
Objective: To evaluate the impact of type-1 diabetes mellitus (DM) and methylenetetrahydrofolate reductase (MTHFR) polymorphisms on impaired placentation leading to early pregnancy loss. Methods: Miscarriage materials were obtained from eight pregnant women with type-1 DM without MTHFR polymorphism, eight with MTHFR polymorphisms without type-1 DM, and eight controls with neither DM nor MTHFR polymorphisms. Insulin-like growth factor-1 (IGF-1), leukemia inhibitory factor (LIF), and Beclin-1 expression were assessed to evaluate placentation. Results: Cytoplasmic LIF, IGF-1, and Beclin-1 expression were decreased in the superficial and glandular epithelial cells of the decidua in both study groups. LIF expression was increased in interstitial trophoblasts in the MTHFR group. IGF-1 expression was decreased in the decidual cells and interstitial trophoblasts in both study groups, while the decrease in stromal cells was noted only in type-1 DM group. Beclin-1 expression was increased in interstitial and villous trophoblasts in both study groups. Conclusion: The expression of IGF-1, LIF, and Beclin-1 are altered in both the decidua and the trophoblasts in pregnancies of women with type-1 DM and MTHFR polymorphisms, compared to normal pregnancies undergoing (elective) terminations.

Abstract
BACKGROUND Extractable nuclear antigen (ENA) and anti-double stranded DNA (anti-dsDNA) positivity and related diseases like systemic lupus erythematosus, Sjögren syndrome, and other autoimmune diseases are known to be associated with obstetrical complications and poor perinatal outcomes. OBJECTIVE To demonstrate the importance of ENA, anti-dsDNA, antiphospholipid (APL), and anticardiolipin (ACL) antibody positivity on pregnancy outcomes. METHODS Ninety one pregnant women with known ENA, anti-dsDNA, APL IgG and IgM, and ACL IgG and IgM antibody positivity were retrospectively compared with 91 randomly selected pregnant woman in terms of obstetrical complications and pregnancy outcomes. Beksac Obstetrics Index-pregnancy (BOIp), calculated as (number of children + (π/10))/gravidity in the current pregnancy, was used to compare the risk level between groups. RESULTS Significant differences were found in the median maternal age, gravidity, number of previous miscarriages, and BOIp between the groups (p= 0.04, p< 0.001, p< 0.001, and p< 0.001, respectively). Significant differences were also found between the study and control groups in the median gestational age at birth, birth weight, and APGAR1 score (p< 0.001 for all). Similarly, significant differences were found between groups in the rates of intra-uterine growth restriction, oligohydramnios, and gestational hypertension (p< 0.001, p= 0.05, and p= 0.05, respectively). There were 3 (3.3%) stillbirths in the study group and none in the control group (p= 0.123). CONCLUSION We evaluated the impact of anti-dsDNA, ENA, APL, and ACL antibody positivity, which may cause immunologic inflammation at placenta and thereby affect pregnancy outcomes.

Abstract
Objective: To evaluate and compare the outcomes of pregnancies with prenatally detected gastroschisis and omphalocele. Materials and Methods: We retrospectively evaluated prenatally detected gastroschisis and omphalocele cases. Cases were compared in terms of maternal demographic and clinical characteristics as well as pregnancy and neonatal outcomes. Results: This study consisted of 17 gastroschisis and 30 omphalocele cases. Only one case with gastroschisis was terminated due to additional severe limb deformities. Seventeen out of 30 cases of omphalocele were terminated for various reasons (56.7%). All patients with gastroschisis had surgical repair, while 8 out of 13 omphalocele cases had surgery. One patient with an omphalocele died after surgery due to sepsis. Six cases of gastroschisis also died in the neonatal period due to various reasons (6/16, 37.5%). Conclusion: Additional genetic disorders are more frequent in those with omphalocele cases, and they are more frequently terminated during gestation that the gastroschisis fetuses.

Abstract
Objective To demonstrate clinical importance of the 75-g glucose tolerance test (GTT) in the prediction of large for gestational age (LGA) fetuses in non-diabetic pregnancies. Methods We retrospectively evaluated 75-g GTT screening results of 356 pregnancies without prompt diagnosis of gestational diabetes mellitus (GDM) between January 2013 and December 2017. Newborns with a birthweight greater than the 90th percentile were evaluated as LGA. Pregnancies with LGA and non-LGA fetuses were compared by demographic and historical factors - maternal age, gravidity, parity, birthweight, birthweek, GTT results and birthweight percentiles - via Student's t-test. Multiple linear regression using the backward elimination method was performed to define the correlation between parameters and LGA (P-value of <0.20 was identified as the threshold). Receiver operator characteristics (ROC) curve analysis was performed for further analysis. Results The cohort was consisted of 45 (12.6%) and 311 (87.4%) pregnancies with LGA and non-LGA fetuses, respectively. Maternal age and 2nd-h GTT results were found to be significantly higher in patients with LGA newborns (P<0.001 and P=0.016, respectively). Fasting glucose levels and GTT 1st-h results were also higher (P=0.112, P=0.065). The coefficient of multiple determination (R2) was 0.055 by multiple linear regression analysis. Accordingly, GTT 2nd-h result and maternal age were statistically significant and contributed to the explanation of LGA, although the R2 value was not that much higher (P=0.016; P=0.001). Maternal age and GTT 2nd-h results were found to be associated with LGA fetuses with area under the curve (AUC) values of 0.662 and 0.608 according to ROC curve analysis. Conclusion Maternal age and 75-g GTT 2nd-h results were significantly higher in gestations with LGA newborns without GDM.
