RESUMEN
PURPOSE: To find out if GnRH agonist (GnRHa) and GnRH antagonist (GnRHant) offer ovarian protection from cyclophosphamide (Cyc) and if AMH expression is affected. METHODS: This experimental study was conducted in Baskent University Animal research laboratory and 66 virgin Wistar albino rats were assigned to six groups. The control group received intraperitoneal saline injection. The GnRHa group had a single dose of leuprolide acetate (1 mg/kg) 28 days prior to saline injection. The GnRHant group had a single dose of cetrorelix acetate (0.1 mg/kg) 1 h prior to saline injection. The Cyc group had a single intraperitoneal dose of Cyc (75 mg/kg). The GnRHa+Cyc group had a single dose of leuprolide acetate (1 mg/kg) 28 days prior to Cyc (75 mg/kg). The GnRHant+Cyc group had single dose of cetrorelix acetate (0.1 mg/kg) 1 h prior to Cyc (75 mg/kg). At day 35, the animals were euthanized, and their ovaries were removed. Primordial follicles were counted and AMH expression was determined. The Kruskal-Wallis, χ(2), or Fisher's exact test was used where appropriate. p < 0.05 was considered statistically significant. RESULTS: PMF count was reduced in GnRHant (p < 0.01) and Cyc (p < 0.01) groups. Cyc, GnRHa+Cyc and GnRHant+Cyc groups had similar numbers of PMF. AMH expression was reduced in Cyc, GnRHa+Cyc and GnRHant+Cyc groups (p < 0.01). CONCLUSION: Neither GnRHa nor GnRHant can offer protection against Cyc-induced damage. GnRHant itself reduces the number of primordial follicles.

OBJECTIVES: The aim of the study was to investigate to what extent sweeping of the membranes contributes to cervical shortening and if cervical shortening is related to the time to onset of labor and duration of the active phase of labor METHODS: This prospective randomized clinical trial was performed at Baskent University between February and March 2011. Women were randomly assigned to receive membrane sweeping (Sweeping Group) (n = 69) or no membrane sweeping (Control Group) (n = 71). Cervical length was measured (cervix1) in both groups by examiner 1 and the Bishop Score was determined in the control group and sweeping was performed in the sweeping group by examiner 2. Two days later the patients had another cervical length measurement (cervix 2) by examiner 1, blinded to the group and results of the examiner 2. t test, Mann-Whitney U test and Chi-square test were used for statistical analyses. RESULTS: Cervix 1 was 27.4 +/- 8.4 mm and 29.6 +/- 8.9 mm (p = 0.14), cervix 2 was 23.3 +/- 8.8 mm and 23.8 +/- 8.5 mm (p = 0.28) and cervical shortening was 5 +/- 4 mm and 5 +/-4 mm (p = 0.446), time to onset of labor was 6.3 +/- 4.6 and 5.7 +/- 4.7 (p = 0.38) and duration of labor was 5.8 +/- 2.89 and 5.7 +/- 2.4 (p = 0.82) for the sweeping and the control groups, respectively CONCLUSIONS: Sweeping of the membranes does not reduce cervical length and does not shorten time to onset of labor and duration of the active phase of labor NCT 1309308: Sweeping the Membranes, Cervical Length and Duration of Labor

PURPOSE: To investigate if normotensive and hypertensive patients with intrauterine growth restricted (IUGR) fetuses were different with respect to maternal and fetal characteristics and Doppler flow. METHODS: The records of patients with IUGR fetuses who had to be delivered before 34th gestational week because of fetal distress were examined. Early Doppler abnormalities were defined as increased umbilical artery resistance and redistribution of blood flow in the middle cerebral artery while late Doppler abnormalities were defined as the absence or reversal of umbilical artery blood flow and Doppler flow changes in venous Doppler. t Test, Chi-square test and Mann-Whitney U test were used for the comparison of data as appropriate. p < 0.05 was considered statistically significant. RESULTS: Thirty-six patients were hypertensive while 42 were normotensive. Gestational week at admission for hypertensive and normotensive groups (30.8 ± 3.6 vs. 32.3 ± 3.1) (p = 0.057), time to delivery (7.1 ± 12.6 vs. 4.3 ± 9.1 days) (p = 0.267) and gestational week at delivery (31.8 ± 3.1 vs. 32.9 ± 2.9) (p = 0.117) were similar. Birth weight was significantly lower (1242 ± 534 vs. 1516 ± 504 g) (p = 0.02) in the normotensive group. The frequency of having oligohydramnios (64.2 % for normotensive and 44.4 % for hypertensive patients) (p = 0.079) was similar in both groups. Early Doppler abnormalities were more common in hypertensive group (75 vs. 40.5 %) (p = 0.001) while late Doppler abnormalities were more common in normotensive group (25 vs. 59.5 %) (p = 0.001). CONCLUSION: Birth weight was lower and late Doppler abnormalities were more common in the normotensive group while early Doppler abnormalities were more common in hypertensive group.

AIM: To investigate whether serum biochemical markers were altered during first trimester screenings in patients who have diminished ovarian reserve. METHODS: One hundred and fifty-one women who conceived after intracytoplasmic sperm injection were enrolled during the 11- to 14-week scan between June 2006 and July 2008. The normoresponders (Group 1: 125 patients) had >6 oocytes and the poor responders (Group 2: 26 patients) had ≤6 oocytes in oocyte retrieval. The means of the multiples of the median (MoM) of pregnancy-associated plasma protein A (PAPP-A), free ß-human chorionic gonadotropin (ß-hCG) and nuchal translucency of the poor responder and normoresponder groups were compared and a potential relationship between serum markers and poor ovarian reserve was investigated. Data were analyzed with the Student's t-test, χ2-test and Mann-Whitney two sample test (unpaired, nonparametric). P < 0.05 was considered significant. RESULTS: The means of the MoMs of the poor responders and normoresponders were 1.16 ± 0.45 and 1.04 ± 0.32 (P = 0.111) for nuchal translucency, 0.92 ± 0.48 and 0.89 ± 0.61 (P = 0.399) for PAPP-A, and 1.08 ± 0.40 and 1.21 ± 0.95 (P = 0.831) for ß-hCG, respectively. CONCLUSION: There was no statistically significant difference between the groups in serum biochemical markers, nuchal translucency means and screen positive rates during the first trimester screening.

With recent advances in prenatal care, the incidence of direct causes of maternal death has declined and indirect causes have gained significant importance. Thromboembolism, hypertension and cardiovascular diseases are the most common indirect causes of maternal death. Acute myocardial infarction, stroke, venous thromboembolism, peripartum cardiomyopathy aortic dissection and amniotic fluid emboli are responsible for the majority of the maternal deaths from cardiovascular causes. The issue of pregnancy of heart transplant--and Turner syndrome--patients requires extensive research. Obstetricians should possess good knowledge of cardiovascular complications of pregnancy because a high index of suspicion and early diagnosis, together with timely and appropriate interventions may save the life of the fetus and the mother.
