    Objective: This study was performed to explore the possibility that each oocyte and its surrounding cumulus cells might have different genetic expression patterns that could affect human reproduction. Methods: Differential gene expression analysis was performed for 10 clusters of cumulus cells obtained from 10 cumulus-oocyte complexes from 10 patients. Same procedures related to oocyte maturation, microinjection, and microarray analyses were performed for each group of cumulus cells. Two differential gene expression analyses were performed: one for the outcome of clinical pregnancy and one for the outcome of live birth. Results: Significant genes resulting from these analyses were selected and the top 20 affected pathways in each group were analyzed. Circadian entrainment is determined to be the most affected pathway for clinical pregnancy, and proteoglycans in cancer pathway is the most affected pathway for live birth. Circadian entrainment is also amongst the 12 pathways that are found to be in top 20 affected pathways for both outcomes, and has both lowest p-value and highest number of times found count. Conclusion: Although further confirmatory studies are necessary, findings of this study suggest that these pathways, especially circadian entrainment in cumulus cells, may be essential for embryo development and pregnancy.

    Spontaneous rupture of a splenic artery aneurysm during the third trimester of pregnancy
    (WALTER DE GRUYTER GMBH, 2017-01-01) Peker, Nuri; Vicdanli, Nazif Harun; Demir, Ahmet; Bozan, Mehmet Bugra; Gundogan, Savas
    Spontaneous rupture of a splenic artery aneurysm (SAA) during pregnancy is a rare but life-threatening situation typically presenting with sudden and unexpected fetal and maternal death. The etiology is unclear

    Adolescent pregnancies and perinatal outcomes: a study at tertiary hospital at the eastern part of Turkey
    (I R O G CANADA, INC, 2018-01-01) Peker, N.; Demir, A.; Aydin, C.; Biler, A.; Gundogan, S.
    Objective: The authors evaluate the clinical features and obstetric outcomes of the adolescent pregnancies at the eastern part of Turkey. Materials and Methods: This is a retrospective study included 550 adolescent pregnant women aged less than 19 years who were followed up and gave birth at Elazig Research and Training Hospital between 2010 and 2013. Results: The 550 pregnant had a mean age of 18 +/- 1.13 (13-19) years, a mean gravidity of 1.19 +/- 0.57 (1-10), a mean parity of 0.15 +/- 0.39 (0-2), and an average number of abortions of 0.03 +/- 0.17 (0-1). Of the 550, 369 (67.1\%) had a spontaneous vaginal delivery (SVD), 179 (32.5\%) had a cesarean delivery, and two (0.4\%) had an abortion. Of the 550, 539 (98\%) had a tenn delivery and 11(2\%) had a preterm delivery at mean gestational week of 31 +/- 2.4 (range, 27-34). No obstetric or postpartum complication occurred in 90.4\% (n=497) of the patients. The most common obstetric complication was intrauterine growth restriction (IUGR) (n=28
