ABSTRACT
BACKGROUND: Our aim was to investigate the changes in neudesin levels in pregnant women with GDM and the relationship between neudesin and metabolic parameters. METHODS: Forty pregnant women diagnosed with GDM and forty age- and gestational week-matched control subjects were included in the study. Demographic data were obtained from records. Maternal lipid profiles, glucose levels, fasting insulin, HbA1C, and HOMA-IR results were compared between the groups. Correlation tests were performed to evaluate the relationship between neudesin and clinical and laboratory diagnostic parameters. p < 0.05 were interpreted as statistically significant. RESULTS: The human serum neudesin levels were significantly lower in the GDM group compared with the controls. The correlation tests showed statistically negative and weak correlations between the neudesin levels and the maternal age, 50 g OGCT, 100 g OGTT 3 hours, and HbA1C. The optimum neudesin cutoff value for a diagnosis of GDM disease is 6.94 ng/dL, with a sensitivity of 65.9% and a specificity of 63.2%. CONCLUSIONS: This study has shown that lower neudesin levels may occur as a reflection of changes in glucose metabolism during intrauterine life.

Objectives: The aim is to use three-dimensional transvaginal ultrasonography (3-D TVUS) to evaluate the success of hysteroscopic metroplasty for the uterine septum and to compare the pregnancy outcomes. Materials and Methods: Thirty-eight patients with uterine septum who had hysteroscopic uterine septum resection were recruited. Preoperative 3-D TVUS measurements of the septal apex to the uterine fundus (s1), septal apex to internal os distance (s2), and intercornual distance (s3) were compared with the postoperative values. The pregnancies of the patients were followed up for a year postoperative period. Results: Out of the 38 patients, thirty-five had partial uterine septum (class U2a), while 3 patients had complete uterine septum (class U2b). Eighteen (47.36%) of the patients who underwent uterine septum resection achieved pregnancy, and thirteen of these pregnancies were (72.2%) term pregnancies, and all term pregnancies resulted in a live birth. Natural conception was achieved in 77.7% (14 of 18) of the patients. Term pregnancy occurred in 68.7% (11 of 16) of the patients with a partial septum and in 66.6% (2 of 3) of the patients with a complete uterine septum. A comparison of the 3-D TVUS measurements of the uterus pre- and postoperatively showed a decrease in s1 and an increase in s2 (P < 0.05). The uterine cavity length of pregnant patients was found to be higher than nonpregnant patients (P < 0.05). Conclusion: Reproductive results of hysteroscopic metroplasty were favorable in achieving live and term birth. three-dimensional TVUS can be preferred as a noninvasive effective method in objective evaluation of the success of the hysteroscopic surgery.
ABSTRACT
Objective: Cesarean section (CS) rates continue to rise globally because of various factors. Medically unnecessary cesarean operations have no benefit to the mother or child's health. Since the World Health Organization (WHO) has determined that the acceptable CS rate should not be more than 10-15%, it also stated the use of a classification system to compare different patient groups and facilities. Turkey has the highest CS rates globally and has been rising over the years. This study aims to assess CS rates between 2018 and 2023 using National Health Data and to analyze them according to the Robson classification system and WHO reference values to discuss possible measures against increasing rates. Materials and Methods: In this study, we assessed the rates of CSs between 2018 and 2023; the CS rate including all 5-years and analysis of CS rates for each Robson group as advocated by WHO. Also, another assessment was done of the facilities where the CSs were applied (Public, private, or university hospitals). Results: The total number of births recorded between 2018 and2023 was 6.161.976. The overall CS rate was 57.55%. The number of total CS operations was 3.546.049. The primary CS rate was 28.83% (N:1.776.503). Significant differences were observed between the public and private centers for each Robson group. Conclusion: The CS rates of Groups 1-4 are obviously higher than expected. The CSs of these groups cumulatively affect the rates of other groups. Nulliparous women have CSs mostly in private hospitals. There is a need for improvements in the health system in this regard for better maternal and child health.
ABSTRACT
BACKGROUND/AIM: To assess the clinical and demographic features of maternal mortality cases among patients with cardiac valvular diseases between 2012 and 2019. METHODS: Maternal mortality due to valvular heart disease between January 2012 and December 2019 in Turkey was retrospectively analyzed. The cases were classified according to New York Heart Association (NYHA) classification based on the severity of the heart disease. NYHA classification groups were divided into two; as class I-II (n = 34) and class III-IV (n = 31). Two groups were compared in terms of demographic and clinical characteristics. RESULTS: Valvular heart disease was diagnosed in 41 (63.1%) of the cases before pregnancy. It was found that 100% (n = 21) of the warfarin users had switched to low molecular weight heparin treatment due to concerns about warfarin embryopathy after the diagnosis of pregnancy, and only 14.2% (n = 3) of them had been monitorized with Antifactor Xa activity to evaluate the effectiveness of the medication. Two NYHA groups had similar clinical characteristics. Intensive care unit admission rate, frequency of prosthetic valve, rate of thromboprophylaxis, type of valvular disease and reasons of maternal death were similar between the NYHA groups (p < 0.05). CONCLUSION: Maternal mortality may be observed in cases with NYHA class I-II in almost similar rates with NYHA class III-IV. Therefore, it is crucial to adequately assess the mortality risk of pregnant women with cardiac valvular pathologies and to achieve early diagnosis and appropriate treatment in order to reduce maternal mortality.

OBJECTIVE: Gestational diabetes mellitus (GDM) is defined as glucose intolerance detected during pregnancy. GDM is increasing worldwide and is associated with adverse maternal and fetal outcomes. Neuregulin 4 (NGR4) is epidermal growth factor like signaling molecule. It plays an important role in cell to cell communication furthermore recent studies indicate that NRG4 may work as a novel adipokine with a possible role in maintaining energy and metabolic homeostasis. The aim of the present study was to assess serum NRG4 levels along with several metabolic parameters in patients diagnosed with gestational diabetic mellitus. MATERIALS AND METHODS: In this prospective cross-sectional study, the study group was composed of 63 women with GDM and 64 healthy pregnant women matched for age, body mass index (BMI) and gestational age. Blood samples were collected at the 24-28th gestational weeks. Serum NRG4, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides, glucose levels during 75-gr OGTT, fasting insulin, glycosylated hemoglobin A1c (HbA1c), alanine aminotransferase (ALT) and creatinine levels were measured. Homeostasis model assessment of insulin resistance (HOMA-IR) values were calculated. RESULTS: Serum NRG4 values were significantly elevated in the GDM group compared to the control group (p < .001). Multivariate linear regression analyzes revealed that BMI (ß = 0.910, p < .001), glucose 2-h OGTT (ß = 0.866, p < .001) and HOMA-IR (ß = 0.222, p < .001) independently and positively predicted NRG4 levels. CONCLUSIONS: Serum NRG4 levels were associated with metabolic parameters of GDM. The present study can be considered to be a guide for future studies to clarify the pathophysiology of NGR4 in GDM patients.

INTRODUCTION: Erectile dysfunction (ED) worsens in men with diabetes. Human umbilical cord blood (HUCB), because of its widespread availability and low immunogenicity, is a valuable source for stem cell-based therapies. AIM: To determine the effect of intracavernous injection of HUCB mononuclear cells (MNCs) on ED in rats with diabetes induced by streptozotocin. METHODS: Thirty adult male Sprague-Dawley rats were equally divided into three groups: (i) control, (ii) diabetes induced by streptozotocin (35 mg/kg intravenously for 8 weeks), and (iii) diabetic rats treated with MNCs (1 × 106 cells by intracavernosal injection). The HUCB-MNCs isolated by the Ficoll-Hypaque technique were obtained from eight healthy donors and administered to diabetic rats after 4 weeks. MAIN OUTCOME MEASURES: The ratio of intracavernosal pressure to mean arterial pressure ratio; the protein expression of endothelial and neuronal markers, such as von Willebrand factor, neuronal nitric oxide synthase, hypoxia-inducible factor-1α, and vascular endothelium growth factor; and the relative area of smooth muscle to collagen using western blotting and Masson trichrome staining were determined. RESULTS: Diabetic rats demonstrated a significantly decreased ratio of intracavernosal pressure to mean arterial pressure (0.26 ± 0.04; P < .01) and treatment with MNCs restored erectile function in diabetic rats (0.67 ± 0.05) compared with control rats (0.56 ± 0.02). In bath studies, neurogenic relaxant and contractile responses were significantly decreased in diabetic cavernosal tissues, which were restored by treatment. The ratio of smooth muscle to collagen was partly recovered by treatment, whereas von Willebrand factor levels were not altered in any group. Neuronal nitric oxide synthase and vascular endothelium growth factor levels were decreased, which were not restored by treatment. Increased hypoxia-inducible factor-1α protein expression in the diabetic group was completely normalized in MNC-treated diabetic samples. CONCLUSION: These results suggest that HUCB-MNC treatment can enhance the recovery of erectile function and promote numerous activities such the contribution of the hypoxia-inducible factor-1α and von Willebrand factor pathway to the neurogenic erectile response of diabetic rats. HUCB-MNCs in the healing process could involve an adaptive regenerative response and appear to be a potential candidate for cell-based therapy in ED of men with diabetes. It is evident that HUCB could provide a realistic therapeutic modality for the treatment of diabetic ED.

OBJECTIVE: To investigate Wnt1-inducible signaling pathway protein-1 (WISP1) levels and their correlation with metabolic parameters in pregnant women with gestational diabetes mellitus (GDM) and non-GDM healthy pregnant women. MATERIALS AND METHODS: In this prospective cross-sectional study, the study group was composed of 62 women with GDM and 73 healthy pregnant women matched for age, body mass index (BMI) and gestational age. Blood samples were collected at 25-29th gestational week. Serum WISP1, betatrophin, glucose, fasting insulin, glycosylated hemoglobin A1c, total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol, C reactive protein, alanine aminotransferase and creatinine levels were measured. Homeostasis model assessment of insulin resistance (HOMA-IR) values was calculated. The level of significance was accepted as p < 0.05. RESULTS: Circulating WISP1 in the GDM group was significantly higher than the control group (p <0.001). Further, WISP1 was positively correlated with BMI, HOMA-IR values and fasting glucose, fasting insulin, triglyceride, betatrophin levels. BMI, HOMA-IR and betatrophin independently and positively predicted WISP1 levels. CONCLUSION: These results demonstrate a relationship between WISP1 and the metabolic parameters of GDM. And, WISP1 might be involved in the pathophysiology of GDM. As a part of this pathophysiological mechanism, the activation of WISP1 and betatrophin might take place through several ways; WISP1 and betatrophin might either use same signaling pathways and potentiate each other or they might also constitute the sequential steps of a common pathway.

OBJECTIVE: To determine the levels of WISP1 and betatrophin in normal weight and obese women with polycystic ovary syndrome (PCOS) and to assess their relationship with anti-Müllerian hormone (AMH) levels, atherogenic profile and metabolic parameters Methods: In this prospective cross-sectional study, the study group was composed of 49 normal weighed and 34 obese women with PCOS diagnosed based on the Rotterdam criteria; 36 normal weight and 26 obese age matched non-hyperandrogenemic women with regular menstrual cycle. Serum WISP1, betatrophin, homeostasis model assessment of insulin resistance (HOMA-IR) and AMH levels were evaluated. Univariate and multivariate analyses were performed between betatrophin, WISP1 levels and AMH levels, metabolic and atherogenic parameters. RESULTS: Serum WISP1 and betatrophin values were elevated in the PCOS group than in the control group. Moreover, serum WISP1 and betatrophin levels were higher in the obese PCOS subgroup than in normal weight and obese control subgroups. Multivariate analyses revealed that Body mass index, HOMA-IR, AMH independently and positively predicted WISP1 levels. Serum betatrophin level variability was explained by homocysteine, HOMA-IR and androstenedione levels. CONCLUSION: WISP1 and betatrophin may play a key role on the pathogenesis of PCOS.

AIM: Our aim was to evaluate the obstetric outcomes of isolated oligohydramnios during the early-term, full-term, and late-term periods, and to determine the optimal timing of delivery. METHODS: A retrospective study was performed at a tertiary center. Isolated oligohydramnios cases were divided into early-term, full-term, and late-term groups. Evaluated outcomes were fetal birthweight, 5-min Apgar score < 7, meconium-stained amniotic fluid, neonatal intensive care unit admission, transient tachypnea of newborn (TTN), requirement of ventilator, newborn jaundice, mode of delivery, induction of labor, and undiagnosed small-for-gestational-age fetus before delivery. Composite outcome was defined as perinatal outcomes taken together (neonatal intensive care unit admission, TTN, requirement of ventilator, and newborn jaundice). RESULTS: The study period included 1213 cases of term isolated oligohydramnios. Within this cohort there were 347 early-term, 781 full-term and 85 late-term patients. The cesarean rate and the rate of newborn jaundice were higher in early-term cases (37.8% and 3.5%, respectively) than in full-term cases (30.1% and 0.9%, respectively). Meconium-stained amniotic fluid was higher in late-term than full-term cases. Timing of delivery did not affect occurrence of TTN, 5-min Apgar score < 7, ventilator requirement, or composite outcome. In total, 15-17% of isolated oligohydramnios cases involved undetected small-for-gestational-age fetuses. CONCLUSION: As this study was not a randomized controlled trial, a decisive conclusion may not be possible. However, until well-designed controlled studies are conducted, expectant management may be appropriate up to the full-term period and induction of labor may be appropriate management when the full-term period is reached.

OBJECTIVE: Endometriosis is a chronic inflammatory disease pathologically defined as the presence of endometrial-like tissue outside the uterine cavity. It is one of the most important diseases affecting women of reproductive age. The process of endometriotic implant growth is mediated by many complex interactions of immunologic, hormonal, genetic, and environmental mediators. Vitamin C (ascorbic acid), besides playing a role in preventing invasion and metastasis, is an antioxidant having anti-inflammatory and -angiogenic effects. In this study, we aimed to investigate the effect of vitamin C on the prevention and regression of endometriotic implants in a rat model of endometriosis. MATERIALS AND METHODS: This was a prospective, comparative, experimental animal study. After endometriotic implants were induced simultaneously, rats were divided into three groups. Group A was given 500 mg/kg of intravenous vitamin C every 2 days, starting immediately after implantation (n = 11). All rats had a second operation 21 days after the initial one and had the lesion volumes measured. Group B was given 500 mg/kg of intravenous vitamin C every 2 days, starting 21 days after this operation (n = 11). All rats were sacrificed 21 days after the third operation. Implant volume, weight measurements, and histopathological evaluation of the lesions were carried out. Group A received vitamin C throughout the study, while Group C (n = 11) was not given any medication. The findings in the three groups were compared. RESULTS: At the second laparotomy after the induction, Group A had the smallest implant volume with a statistically significant difference compared to Group B (p = 0.012). The end-of-study volumes of endometriotic implants of group B were significantly smaller than the first volumes (p < 0.05). CONCLUSION: Intravenous vitamin C treatment might have a suppressive effect on the prevention of endometriotic implant induction and regression of endometriotic implant volumes.

INTRODUCTION: This study aimed to document the prevalence of syphilis among pregnant women in Turkey. METHODOLOGY: In this retrospective cohort study, a total of 63,276 sera obtained between January 2007 and June 2014 from women who were routinely screened for syphilis as a part of antenatal care at a tertiary referral hospital in Turkey were analyzed. Serological screening was done with the rapid plasma reagin (RPR) test on venous blood samples. Treponema pallidum hemagglutination assay (TPHA) was the confirmation test for the diagnosis of syphilis in patients who had positive results in the screening test. RESULTS: Between 2007 and the first six months of 2014, 41 RPR+ and only five confirmed syphilis-positive patients were determined. The syphilis seroprevalence rate was 0.0648%. Within these years, there was no case of congenital syphilis detected in the hospital. CONCLUSION: As there is evidence of effective screening of syphilis contributing to the effective treatment and prevention of adverse outcomes, routine antenatal screening of syphilis is recommended. The rationale depends on the consideration of the serious results of not treating the disease and the cost effectiveness of screening.

BACKGROUND AND OBJECTIVES: Even though the 50 g oral glucose challenge test (GCT) is the most commonly used screening modality for gestational diabetes mellitus (GDM), no consensus for the diagnostic approach is available to patients with a markedly elevated GCT result. We aimed to evaluate the diagnostic utility of markedly elevated GCT results and the impact of age using the oral glucose tolerance test (OGTT) as gold standard. DESIGN AND SETTING: Retrospective study conducted in a women's hospital in Ankara, among patients who underwent GCT from January 2005 to December 2008. PATIENTS AND METHODS: In this retrospective study, we included 626 pregnant women who underwent a 3-hour 100 g OGTT after a GCT result ≥180 mg/dL among 29842 women. We calculated positive predictive values (PPV) of each GCT category to diagnose GDM and both GDM and gestational impaired glucose tolerance (GIGT). RESULTS: A GCT result of ≥240 mg/dL provided 100% PPV for the diagnosis of GDM and a result of ≥230 mg/ dL provided 100% PPV for the diagnosis of GDM + gestational impaired glucose tolerance (GIGT), according to both, National Diabetes Data Group (NDDG) and Carpenter and Coustan (CC) criteria. A result of ≥200 mg/ dL provided 100% PPV for diagnosing GDM+GIGT in patients older than 35 years, according to the CC criteria. CONCLUSIONS: The GCT result of 200 mg/dL is an ideal cutoff value for the diagnosis of GDM + GIGT in patients ≥35 years, and OGTT can be omitted in these patients. In younger patients, the cutoff value should be chosen as 230 mg/dL.

Cytokines modulate turnover of the endometrium during the menstrual cycle and contribute to the pathogenesis of endometriosis. Gene expression for cytokines is often regulated by proteins that bind to adenosine- and uridine-rich elements (AREs) in their transcripts to stabilize or destabilize bound messenger RNAs (mRNAs). HuR/ELAVL1 is an RNA-binding protein that stabilizes ARE-containing mRNAs. We hypothesized that HuR might play a role in regulating cytokine expression during the menstrual cycle and in endometriosis and characterized the expression and regulation of HuR in eutopic and ectopic human endometrium. Tissue sections obtained from normal (n = 23) and ectopic (n = 16) endometrium were immunostained for HuR, and staining intensity was evaluated by HSCORE. Cultured stromal cells isolated from normal endometrium were treated with vehicle, estradiol (E2), progesterone (P), E2 + P, tumor necrosis factor-α (TNF-α), and interleukin 1ß (IL-1ß) for 24 hours, and HuR expression was determined by Western blot. HuR immunoreactivity was significantly lower in the early proliferative and late secretory phases (157.5 ± 11.08 and 190.0 ± 15.2, respectively), compared to the mid-late proliferative (270.0 ± 8.0) and early-mid secretory phases (256.6 ± 20.2; P < .01, analysis of variance [ANOVA]). Furthermore, HuR expression was significantly lower in ectopic endometrial cells compared to normal endometrium in mid-late proliferative and early-mid-secretory phases (P < .01). Estrogen, P, or cytokines did not alter HuR expression in cultured endometrial stromal cells. Increased HuR levels in the mid-menstrual phases are likely to contribute to reduced mid-cycle cytokine expression and enhanced cellular survival in eutopic endometrium. In ectopic endometrium, elevated cytokine levels associated with endometriosis likely reduce HuR expression.
