To identify changing trends in peripartum hysterectomy (PH), both elective. cesarean hysterectomy and emergency cesarean hysterectomy, at a single training and research hospital over the last 17 years in Istanbul, Turkey. A retrospective cohort study was performed between January 2001 and September 2017. The records of all patients who had PH at Kanuni Sultan Süleyman Training and Research Hospital were analyzed. There were 243 cases of PH during the study period. A total of 266,386 births occurred, of which 60.1% were vaginal deliveries and 39.8% were cesarean sections. The incidence of PH increased from 0.67 per 1000 deliveries to 1.14 per 1000 deliveries during 2001-2008 and 2009-2017, respectively, with an overall incidence of 0.91 per 1000 deliveries during the 17 years. The main indication for PH changed significantly during this time from uterine atony (57.1%) to placenta accreta spectrum (85%). About 37% of women who underwent PH had at least one previous cesarean delivery during 2001-2008, whereas that percentage increased to 95.4% during 2009-2017. Placenta accreta spectrum was the leading cause of PH and was associated with significant maternal morbidity and mortality.

Objective: Gremlin 1 and 2 regulate oocyte primordial follicle transition in animal models. The main objective of this study is to measure the blood levels of Gremlin 1 and 2 in the women with Polycystic Ovary Syndrome (PCOS). We also aimed to evaluate the association of these markers with hormonal and biochemical parameters of PCOS as interrupted folliculogenesis in those women is related to metabolic dysfunction. Material and methods: Fifty women with PCOS were diagnosed according to Rotterdam criteria, and thirty age-matched female controls were included in this prospective study. Gremlin 1 and 2 levels along with hormonal and metabolic parameters were compared between PCOS and control groups. Results: Serum Gremlin 1 levels were significantly higher in the PCOS group than in the control group (p = .001). Gremlin 2 levels were similar between the groups. Besides, there was a significant positive correlation between Gremlin 1 and insulin levels, Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) and waist to hip ratio (WHR) (r = 0.305; r = 0.297; r = 0.303, respectively). Conclusion: Our data suggest that Gremlin 1 may be the key regulator in the pathogenesis of PCOS. In future, Gremlin 1 may be a novel therapeutic target for the treatment of PCOS.

To investigate whether prior testis magnetic resonance spectroscopy (MRS) predicts the success or failure of micro-dissection testicular sperm extraction (micro-TESE) in patients with non-obstructive azoospermia (NOA). Nine men with NOA who were scheduled for micro-TESE for the first time, 9 NOA men with a history of previous micro-TESE and 5 fertile men were enrolled. All NOA patients and fertile controls underwent testis spectroscopy. A multi-voxel spectroscopy sequence was used. Testicular signals of choline (Cho), creatine (Cr), myo-inositol (MI), lactate, and lipids were analyzed quantitatively and compared with the results of the micro-TESEs. The most prominent peaks were Cho and Cr in the fertile controls and NOA subjects with positive sperm retrieval in the micro-TESE. A high Cho peak was detected in 87% of the NOA men with positive sperm retrieval. NOA men without sperm at the previous micro-TESE showed a marked decrease in Cho and Cr signals. For positive sperm retrieval in micro-TESE, the cut-off value of Cho was 1.46 ppm, the cut-off value of Cr was 1.43 ppm, and the cut-off value of MI was 0.79 ppm. Testis spectroscopy can be used as a non-invasive screening method to predict the success or failure of micro-TESE.

Aim: To compare the rates of surgical wound infection in women who have undergone cesarean delivery with subcuticular skin closure with polyglactin 910 or polypropylene. Methods: Between April 2018 and October 2018, patients who had undergone a cesarean delivery for any reason were randomized with polyglactin 910 or polypropylene for subcuticular skin closure. Participants were evaluated for wound complications on day 7 and 30 postoperatively. The primary outcome was surgical site infection within the first 30 days following delivery. In addition, factors affecting surgical site infections were analyzed by binary regression. Results: A total of 220 women who had undergone cesarean delivery were randomized and 213 were included in the final analysis. The groups were similar in terms of demographic characteristics and perioperative features. No statistically significant difference was observed between the groups in terms of wound complications or superficial site infections (8.3% in the polypropylene group versus 10.6% in the polyglactin 910 group, p = .642). Similarly, no difference was observed between the groups in terms of other wound complications. A binary logistic regression analysis indicated that superficial wound site infection was not affected by gravidity, BMI, duration of operation, repeated or unplanned cesarean delivery. Conclusion: It was observed that surgical site infections and other wound complications in skin closures with polyglactin 910 were similar to those with polypropylene.

Objective(s): Chromosomal abnormalities are more commonly seen in embryos with decreased oocyte quality. Therefore aneuploidy due to diminished ovarian reserve may be one of the causative reasons of RPL. We investigated the relationship between ovarian reserve markers especially serum antimullerian hormone (AMH) level and antral follicle count (AFC) and recurrent pregnancy loss (RPL). Materials and methods: This prospective cross-sectional clinical trial including 88 women with RPL and 84 age-matched women without RPL. Results: There were statistically significant differences in body mass index, live birth number, menstrual cycle length, AFC and serum AMH level between groups. There was no statistically significant difference between groups regarding age, menstrual cycle regularity and serum follicle stimulating hormone (FSH) and estradiol (E ₂ ) levels. The percentage of women with levels of AMH<1 was 21.4% in the RPL group and 11.4% in the control group. AFC <7 in both ovaries was lower in the RPL group when compared with the control group (73.8% vs 44.3%, respectively). Conclusion(s): Serum AMH levels and AFC can be assessed in patients with RPL as a part of the work up parameters. Lower Serum AMH levels and AFC especially may predict the quantity of oocytes that may be consequently be related with RPL.
