Follicular fluid oxidative stress biomarkers and ART outcomes in PCOS women undergoing in vitro fertilization: A cross-sectional study
Background: Polycystic ovarian syndrome (PCOS) is the most common cause of anovulatory infertility. Oxidative stress (OS), which plays an important role in determining the developmental competence of an oocyte, may be involved in understanding infertility and poor outcomes cycles in PCOS women undergoing in vitro fertilization (IVF).
Objective: To measure OS biomarkers in the follicular fluid of PCOS women undergoing IVF.
Materials and Methods: In this cross-sectional study, 100 women with PCOS (n = 43) and tubal factor (n = 57) undergoing IVF, who were referred to a tertiary medical center between January 2016 and September 2017 were enrolled. OS markers like reactive oxygen species (ROS), total antioxidant capacity (TAC), and 8-Isoprostane (8-IP) were tested in the follicular fluid and various IVF outcomes in the form of oocytes retrieved, fertilized, cleavage rate, grading of embryos and pregnancy outcomes were compared between the two groups.
Results: The results indicated that the levels of ROS, TAC, and 8-IP were higher in the PCOS group compared to the tubal group (p = 0.21, p = 0.95, and p < 0.05, respectively). Biomarkers based on the number of retrieved oocytes, cleavage rate, and grades of embryos did not differ significantly in the two groups. The median ROS, TAC, and 8-IP were not significantly different in the two groups in relation to the pregnancies, although the 8-IP levels were significantly raised in the PCOS women who had a miscarriage (p = 0.02).
Conclusion: This study concluded the possible role of OS in PCOS women with increased higher level of 8-IP biomarker as a potential biomarker that needs further evaluation.

Role of pelvic and para-aortic lymphadenectomy in epithelial ovarian cancers
Background: Lymphadenectomy in epithelial ovarian cancers has remained a controversial subject. Lack of robust evidence on survival benefits and surgical morbidity associated questions its role in the era of adjuvant chemotherapy. The present study assessed pelvic and para-aortic lymph node removal in epithelial ovarian cancer in Indian women and tried to find clinicopathological correlation of nodal involvement and postoperative implications of lymphadenectomy.Methods: Thirty patients with diagnosis of epithelial ovarian cancer posted for primary debulking surgery were recruited and underwent staging laparotomy along with pelvic and para-aortic lymphadenectomy. Nodal involvement was confirmed on histopathology and various parameters which could predict nodal metastasis were assessed. Patients were followed up for 12 months post-surgery.Results: Nodal yield was ten for pelvic and four for paraaortic nodes. Pelvic node involvement was seen in 26.6% (8/30) of the patients and para-aortic in 15% (3/20) of the patients. Serous histology, higher grade, stage 3 and above, positive peritoneal cytology, omental involvement showed a higher lymph node involvement though not statistically significant. Para-aortic lymphadenectomy was associated with increased operating time, blood loss and longer hospital stay.Conclusions: Lymphadenectomy increases morbidity and decision should be based on predictors of nodal involvement
