Early GnRH-agonist therapy does not negatively impact the endometrial repair process or live birth rate.

Study objective: To investigate whether different timings of GnRH-a downregulation affected assisted reproductive outcomes in infertile women with moderate-to-severe intrauterine adhesions (IUAs) accompanied by adenomyosis. Design: A retrospective case series. Setting: An assisted reproductive technology center. Patients: The study reviewed 123 infertile women with moderate-to-severe IUAs accompanied by adenomyosis undergoing their first frozen-thawed embryo transfer (FET) cycles between January 2019 and December 2021. Measurements and main results: The majority of patients had moderate IUA (n=116, 94.31%). The average Basal uterine volume was 73.58 ± 36.50 cm3. The mean interval from operation to the first downregulation was 21.07 ± 18.02 days (range, 1-79 days). The mean duration of hormone replacement therapy (HRT) was 16.93 ± 6.29 days. The average endometrial thickness on the day before transfer was 10.83 ± 1.75 mm. A total of 70 women achieved clinical pregnancy (56.91%). Perinatal outcomes included live birth (n=47, 67.14%), early miscarriage (n=18, 25.71%), and late miscarriage (n=5, 7.14%). The time interval between uterine operation and the first downregulation was not a significant variable affecting live birth. Maternal age was the only risk factor associated with live birth (OR:0.89; 95% CI: 0.79-0.99, P=0.041). Conclusions: The earlier initiation of GnRH-a to suppress adenomyosis prior to endometrial preparation for frozen embryo transfer did not negatively impact repair of the endometrium after resection.

Low expression of KIF7 indicates poor prognosis in epithelial ovarian cancer.

The aim of the present study was to investigate kinesin family member 7 (KIF7) expression in epithelial ovarian cancer tissues (paraffin-embedded tissues and fresh) and to explore its expression, association with clinicopathological parameters and prognostic value in patients with epithelial ovarian cancer. A total of 113 paraffin-embedded tumor tissues of epithelial ovarian cancer patients diagnosed and operated at the memorial hospital of Sun Yat-sen University Between December 2009 and March 2017 and 41 paratumor tissues were collected for the present study and were assessed for KIF7 expression using immunohistochemistry. Furthermore, 22 fresh epithelial ovarian cancer tissues and their matched paratumor tissues were collected from the Integrated Hospital of Traditional Chinese Medicine, Southern Medical University, between August 2013 and March 2019 and subjected to reverse-transcription quantitative PCR analysis to detect the mRNA expression of KIF7. The expression of KIF7 was lower in cancer tissues than in paratumor tissues, and KIF7 expression was associated with recurrence-free survival and overall survival in epithelial ovarian cancer patients. Furthermore, multivariate logistic regression analysis indicated that low KIF7 expression was an independent predictor of poor survival in patients with epithelial ovarian cancer. In conclusion, KIF7 has a tumor suppressor role in epithelial ovarian cancer and is a useful independent prognostic predictor. It may hold important value for the clinical diagnosis and treatment of epithelial ovarian cancer.
