Öğe Are insulin resistance and serum resistin levels increased in women with idiopathic hirsutism?(Verduci Publisher, 2014) Erkan, Müşerref; Albayrak, Mustafa; Karataş, Ahmet; Keskin, Fatih; Aydın, YusufOBJECTIVE: To investigate the insulin resistance and serum resistin levels in women with idiopathic hirsutism compared to controls and women with polycystic ovary syndrome (PCOS). PATIENTS AND METHODS: Three groups of women including 23 women with idiopathic hirsutism, 28 women with PCOS and 28 non-hirsute women serving as controls were included into the study. The Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), serum fasting insulin and resistin levels were compared between the groups. RESULTS: There were no statistically significant differences regarding the age, BMI and waist circumferences between the groups. Mean and median fasting blood glucose, fasting insulin, HOMA-IR, serum resistin levels were statistically similar between the groups (p = 0.966, p = 0.378, p = 0.409 and p = 0.784, respectively). There were no correlations between the resistin, HOMA-IR, fasting insulin levels and BMI in any of the three groups. CONCLUSIONS: Insulin resistance and serum resistin levels do not appear to be increased in women with idiopathic hirsutism compared to controls at similar BMI's and waist circumferences.Öğe EARLY NEONATAL OUTCOMES IN PATIENTS WITH LATE PRETERM BIRTH(Galenos Publ House, 2013) Karatas, Ahmet; Albayrak, Mustafa; Keskin, Fatih; Biyik, Ismail; Okur, Mesut; Gunes, Cemalettin; Kose, Seyit AliObjective: Preterm deliveries increased in many countries in recent years. However, despite fetal lung maturity, substantial neonatal morbidity may occur even after 34 weeks of gestation. The aim of this study was to evaluate neonatal morbidity and mortality in women with late preterm births. Design: Retrospective. Setting: Duzce University School of Medicine, Departments of Obstetrics and Gynecology and Pediatri Clinics. Patients: Medical records of 291 pregnant women and newborns born between the 340/7-366/7 weeks of gestation were reviewed. Interventions: The whole population is first divided into two groups as depending on the presence of PPROM or not; and then also divided into-three groups based on the gestational age at delivery as 34(0/7)-34(6/7) week (Group 1), 35(0/7)-35(6/7) week (Group 2), and 36(0/7)-36(6/7) week (Group 3). Main outcome measures: Groups were compared with respect to neonatal complications related to prematurity, and early membrane rupture. Results: Of the 291 neonates included in the study, 85 were delivered preterm due to PPROM, 206 were non-PPROM group, and 76 were in Group 1, 108 were in Group 2, and 107 were in Group 3. Sepsis rate was higher in Group 1 and 2 compared to Group 3 (p=0.016, p=0.029). NICU stay period was longer in Group 1 and Group 2 than group 3 (p=0.028, p=0.015 respectively). Newborns in Group 1 had significantly longer hospital stay than Group 3 (p=0.010), and total hospital stay period were significantly higher in newborns with sepsis. Conclusions: The late-preterm infants especially in earlier weeks represent a significantly higher risk category for neonatal complications, and they have a significantly longer NICU and hospital stay period.Öğe Early neonatal outcomes in patients with late preterm birth(2013) Karataş, Ahmet; Albayrak, Mustafa; Keskin, Fatih; Biyik, Ismail; Okur, Mesut; Güneş, Cemalettin; Köse, Seyit AliObjective: Preterm deliveries increased in many countries in recent years.

We aimed to investigate the association of three different polymorphisms of eNOS (promoter -786T/C, exon 894 G/T and intron G10T) with unexplained female infertility. Materials and Methods: Two groups of patients were included in the study: (1) women with unexplained infertility and (2) healthy, fertile women with normal menstrual cycles. eNOS polymorphisms were studied in genomic DNA of each patient by polynnerase chain reaction-restriction fragment length polymorphism method. Results: Forty-one women with unexplained infertility and 40 fertile women were included. Baseline physical characteristics and hormonal parameters of the two groups were similar. For eNOS exon 894 G/T polymorphism, the GG honnozygotes were significantly lower and the heterozygotes GT were significantly higher in the infertile group than in the control group (p < 0.05). eNOS gene polymorphism both for promoter and intron were similar in the two groups (p > 0.05). Conclusion: Altered eNOS protein caused by eNOS exon 894 G/T polymorphism might cause implantation failure, which may be a possible cause of unexplained female infertility. (C) 2014 S. Karger AG, BaselÖğe Geç preterm doğum olgularında erken neonatal sonuçlar(2013) Karataş, Ahmet; Albayrak, Mustafa; Keskin, Fatih; Bıyık, İsmail; Okur, MesutAmaç: Preterm doğumlar son zamanlarda birçok ülkede artış göstermiştir. Fetal akciğerin gelişmiş olmasına rağmen, 34. gebelik haftasından sonra bile ciddi yenidoğan morbiditesi meydana gelebilir. Bu çalışmanın amacı, geç preterm doğum olgularında neonatal morbidite ve mortaliteyi araştırmaktır. Planlama: Retrospektif Ortam: Düzce Üniversitesi Tıp Fakültesi, Kadın Hastalıkları-Doğum ve Pediatri Kliniği Hastalar: 340/7-366/7 gebelik haftasında doğum yapan 291 gebe kadın ve yenidoğanlar incelendi. Girişim: Çalışmaya dahil edilen olgular PPROM varlığı ya da yokluğuna göre öncelikle iki gruba ayrıldı. Daha sonra gruplar, tekrar gebelik haftasına göre kendi içlerinde, 340/7-346/7 hafta olanlar(grup 1),350/7-356/7 hafta olanlar (grup 2), 360/7-366/7 hafta olanlar(grup 3) şeklinde üçe ayrıldı. Değerlendirme parametreleri: Gruplar prematürite ve erken membran rüptürü ile ilişkili yenidoğan komplikasyonları açısından karşılaştırıldı. Sonuç: Çalışmaya dahil edilen ikiyüz doksanbir olgunun 85'i PPROM nedeniyle erken doğum yapmıştı. 206'sı PPROM olmayan gruptaydı ve 76'sı 1. grup, 108'i 2. grup, 107'si de 3. grupta yer aldı. Sepsis oranı, birinci ve ikinci grupta üçüncü gruba göre daha yüksekti (p:0.016, p:0.029). Yenidoğan yoğunbakım ünitesinde (YDYB) kalış süresi 3. gruba oranla, 1. ve 2. grupta daha yüksekti (sırasıyla p:0.028, p:0.015). Birinci gruptaki yenidoğanlar, üçüncü gruptakilere göre anlamlı olarak daha uzun hastanede kalış süresine sahipti (p=0.010), ve toplam hastanede kalış süresi sepsisli yenidoğanlarda anlamlı olarak daha yüksekti. Yorum: Özellikle daha erken gebelik haftalarında olan geç preterm yenidoğanlar, yenidoğan komplikasyonları için anlamlı olarak daha fazla risklidirler, aynı zamanda anlamlı olarak yenidoğan yoğun bakım ve hastanede daha uzun kalış süresine sahiptir.Öğe Maternal serum soluble HLA-G levels in missed abortions(Mdpi, 2013) Keskin, Fatih; Karataş, Ahmet; Albayrak, Mustafa; Bıyık, İsmail; Erkan, MüşerrefBackground and Objective. It is unclear how immune tolerance develops to a semiallograft fetus in pregnancy. Human leukocyte antigen G (HLA-G) expressed by extravascular trophoblasts plays an important role in the recognition of the gestational tissues as self and the development of immune tolerance against the gestational tissues by the maternal immune system. The soluble form of the HLA-G (sHLA-G) molecule in the maternal serum is also reported to contribute to the prevention of rejection during pregnancy. The aim of the study was to compare the maternal serum sHLA-G levels of the women with missed abortions and control subjects with uncomplicated pregnancies. Material and Methods. The prospective cross-sectional study involving 40 with missed abortions and 40 control women, matched by age, gestational age, and body mass index, was carried out. The study group consisted of the women with singleton pregnancies, who were diagnosed with a missed abortion. Only the patients who were confirmed to have an uncomplicated term delivery during follow-up were included in the control group. The serum sHLA-G level was compared between the groups. Results. There was no significant difference in the mean serum sHLA-G levels in terms of gravidity (P=0.761) and a history of abortion (P=0.379) in the control group. The median serum sHLA-G level in the missed abortion group was significantly lower compared with the control group (16.8 [8.5-35.8] vs. 26 [11-135] U/mL, P<0.001). All the women in the control group had uncomplicated term deliveries. Conclusion. Our results showed that the women with missed abortions had significantly lower serum sHLA-G levels compared with the healthy pregnant controls, which may have potentially played a role in the impairment of physiological immunological tolerance during pregnancy. However, the determination of the exact role and the potential clinical utility of maternal serum sHLA-G for the detection/ prediction of a missed abortion risk requires further detailed studies.
