    Purpose We evaluated the protective effect of PRP on ovarian function in female rats with cyclophosphamide (Cy)-induced ovarian damage. Methods Thirty-two adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose ip injection), group 2 (Cy); 75 mg/kg, single-dose ip injection and sodium chloride 0.9% (1 mL/kg, single-dose ip injection), group 3 Cy plus PRP, Cy (75 mg/kg, single-dose and PRP (200 mu l, single-dose) ip injection), group 4 (PRP, 200 mu l, single-dose ip injection). Primordial, antral, and atretic follicle counts; serum anti-Mullerian hormone (AMH) levels; AMH-positive granulosa cells; and gene expression analysis of Ddx4 were assessed. Results Serum AMH levels were significantly lower in group 2 compared to groups 1, 3, and 4 (p < 0.01, p < 0.01, and p = 0.04, respectively). A significant difference was found in the primordial, primary, secondary, antral, and atretic follicle counts between all groups (p < 0.01). There was a statistically significant difference in AMH-positive staining primary, secondary, and antral follicles count between the groups (p < 0.01). There was a statistically significant difference in primary, secondary, and antral AMH positive staining follicle intensity score between the groups (p < 0.01). Ddx4 expression in group 4 was highest compared to other groups. Conclusion Our study may provide evidence that PRP could protect ovarian function against ovarian damage induced by Cy. It could lead to improved primordial, primary, secondary, and antral follicle numbers.

    The predictive value of weight gain and waist circumference for gestational diabetes mellitus
    (2019-09-01T00:00:00Z) TAKMAZ, TAHA; Yalvac, Ethem Serdar; ÖZCAN, Pınar; Coban, Ulas; Karasu, AYŞE FİLİZ; Unsal, Mehmet; TAKMAZ, TAHA; ÖZCAN, PINAR; GÖKMEN KARASU, AYŞE FİLİZ
    Objective: The first objective of this study was to investigate the relationship between gestational diabetes mellitus (GDM) and gestational weight gain (WG), waist circumference (WC), prepregnancy, and gestational body mass index (BMI). The second aim of our study was to assess the ability of WG, WC, prepregnancy, and gestational BMI with special reference to their cut-off points on predicting the risk of GDM in pregnant women in Turkey.

    Are chronotype and subjective sleep quality associated with preeclampsia and preterm birth?

    The physiological and physical changes in pregnancy affect the sleep-wake cycle. Limited data exist to evaluate the effect of sleep quality and chronotype during pregnancy on adverse pregnancy outcomes. It is hypothesized that there could be a tendency for the evening chronotype and sleep disturbances to lead to the development of preeclampsia and preterm birth. A total of 313 pregnant women were included. Women were divided into three groups: Group A (control - problem-free), Group B (preeclampsia) and Group C (preterm birth). There were significant differences in the mean PSQI score between the groups (A vs C and A vs B) (p < 0.01). Women in the preterm and the preeclampsia groups reported significantly worse sleep quality. There was a significant difference in the mean MEQ scores between groups (A vs C and A vs B) (p < 0.01). The ratio of the evening-types was significantly higher for the preterm and preeclampsia groups (p < 0.01). Multivariate logistic regression analysis revealed that there is a negative association between preeclampsia/preterm birth and MEQ score, positive association between preeclampsia/preterm birth and PSQI score. Chronotype and sleep quality measurements could provide a simple and feasible way in the prediction of adverse pregnancy outcomes.

    2-D and 3-D ultrasonographic characteristics of the ovary in women with PCOS and multifollicular ovaries
    (2020-10-01T00:00:00Z) Bozkurt, Murat; Kara Bozkurt, Duygu; Kurban, Didem; TAKMAZ, TAHA; ŞEVKET, Osman; ÖZCAN, Pınar; TAKMAZ, TAHA; ŞEVKET, OSMAN; ÖZCAN, PINAR
    In this prospective study, seventy-six patients (PCOS group; n = 36, multifollicular ovary group; n = 40) were evaluated by 2-D and 3-D ultrasonography. VOCAL programme, echogenicity, number of follicles and blood flow parameters were evaluated. The patients with PCOS had a higher total ovarian volume, mean stromal volume and stromal echogenicity (18.6 +/- 4.75 to 10.2 +/- 3.4p .05). 3 D power Doppler parameters included VI, FI, and VFI values of the patients with PCOS were higher when compared to those of the patients with multifollicular ovary (3.82 +/- 2.65 to 1.78 +/- 1.2,p < .01; 50.76 +/- 4.45 to 40.6 +/- 3.64,p = .03; and 2.34 +/- 1.02 to 1.12 +/- 0.65,p = .02, respectively). Our results revealed that total ovarian volume, stromal volume and echogenicity; VFI, VI, and FI could be useful for differential diagnosis in women with PCOS and multifollicular ovaries.Impact statement What is already known on this subject?Ultrasonography is considered the new diagnostic tool for PCOS. Enlarged ovaries with multiple small follicles peripherally located around increased ovarian stroma with increased stromal echogenicity are the sonographic features of polycystic ovaries. What do the results of this study add?3-D Doppler ultrasonography may be more specific in the determination of multifollicular and polycystic ovaries when compared to RI and PI in 2-D Doppler ultrasonography. Moreover, 3-D power Doppler ultrasonography could be useful for differential diagnosis in women with PCOS and multifollicular ovaries. What are the implications of these findings for clinical practice and/or further research?In clinical practice, the differentiation of multifollicular ovaries and polycystic ovaries (PCO) is difficult with the use of 2-D sonography alone. Therefore, 3-D ultrasound and power Doppler may also be used in addition to 2-D ultrasound for the differentiation of multifollicular ovaries and PCO.
