Hysteroscopic Endometrial Resection in Women Treated With Tamoxifen for Breast Cancer Provides Definitive Diagnosis and Effective Long-Term Therapy.

We evaluated resectoscopic surgery for definitive diagnosis and long-term therapy in 16 symptomatic tamoxifen-treated women with breast cancer who presented with abnormal uterine bleeding and/or intrauterine anomalies. Seven pre-menopausal women had benign pre- and post-operative endometrial biopsy, and 4 had benign polyps. At a median of 7 years of follow-up (range 2-8 y), all remained amenorrheic. Of 9 post-menopausal women, pre-operative biopsy was inadequate in 4, benign endometrium was found in 4, and non-atypical endometrial hyperplasia was found in 1. Post-operatively, all had benign pathology, 8 having polyp and 1 leiomyoma. At a median follow-up of 7 years (range 2-13 y), all were amenorrheic, with no recurrence of breast cancer or uterine pathology.

Poor ovarian response as a predictor for live birth in older women undergoing IVF.

Women of advanced age present a major challenge for fertility treatments. This study was designed to assess whether poor ovarian response (POR) according to the Bologna criteria is a significant predictor for live birth in women over 40. The outcomes of subsequent IVF cycles were also studied. The results of 1870 fresh IVF cycles in 1212 women were retrospectively analysed. The live birth per cycle was 3.3 times higher (11.61% versus 3.54%, P < 0.001) in good responders with more than three oocytes collected compared with women with less. Ovarian response defined by oocytes collected, but not by the number of follicles, was independently associated with live birth (odds ratio, 2.0; 95% confidence interval, 1.18 to 3.54; P = 0.009). The occurrence of POR in subsequent IVF cycles was only 55%. No differences in live births were found in persistent POR compared with women with at least one good response. A single episode of POR in a first IVF cycle in older women has a limited predictive value for the outcomes of subsequent cycles. POR in women aged 40-43 years, defined by the number of oocytes retrieved, is a predictor for live birth in IVF.

Effect of vasopressin injection technique on ovarian reserve during laparoscopic cystectomy of ovarian endometriomas: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: To evaluate the effect of injecting vasopressin during laparoscopic excision of ovarian endometriomas on ovarian reserve. EVIDENCE ACQUISITION: Four different databases (PubMed, Cochrane Library, Scopus, and ISI Web of Science) were searched to identify relevant studies in March 2023. We selected randomized controlled trials (RCTs) that compared vasopressin injection in the intervention group versus no injection of vasopressin in the control group among women undergoing laparoscopic cystectomy of ovarian endometriomas. The main outcomes were the amount of bleeding, number of coagulation events, and levels of serum anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH). The available data were extracted and analyzed in a meta-analysis model using RevMan software. EVIDENCE SYNTHESIS: Seven RCTs, involving a total number of 478 patients, were included in our study. The vasopressin group had significantly reduced blood loss amount and number of coagulation events compared to the control group (P=0.004 and P=0.005). There was a significant improvement in the AMH levels within 6 months after surgery in the vasopressin group (MD=0.52, 95% CI: 0.11, 0.93, P=0.01). In addition, the FSH levels within 6 months after laparoscopic cystectomy were significantly reduced with vasopressin injection. CONCLUSIONS: Vasopressin injection during laparoscopic cystectomy of ovarian endometriomas is effective in reducing blood loss amount and frequency of coagulation, as well as protecting the ovarian reserve. More trials are encouraged to confirm our findings.

CO2 laser therapy for management of stress urinary incontinence in women: a systematic review and meta-analysis.

Background: Carbon dioxide (CO2) laser therapy is an emerging treatment for women with stress urinary incontinence (SUI). Objectives: To examine the efficacy of CO2 laser therapy for management of SUI-related symptoms in women. Design: A systematic review and meta-analysis of randomized controlled trials and cohort studies. Data sources and methods: Four databases were screened until January 2023. All efficacy continuous endpoints were assessed via subtraction of the posttreatment from pretreatment values. The data were summarized as mean difference (MD) with 95% confidence interval (CI) using the random-effects model. Results: A total of 15 studies with 700 patients were analyzed. CO2 laser therapy significantly decreased the 1-h pad weights at 3 months [n = 5 studies, MD = -3.656 g, 95% CI (-5.198, -2.113), p < 0.001], 6 months [n = 6 studies, MD = -6.583 g, 95% CI (-11.158, -2.008), p = 0.005], and 12 months [n = 6 studies, MD = -3.726 g, 95% CI (-6.347, -1.106), p = 0.005]. Moreover, CO2 laser therapy significantly decreased the International Consultation of Incontinence Questionnaire-Urinary Incontinence Short Form Scores at 3 months [n = 10 studies, MD = -4.805, 95% CI (-5.985, -3.626), p < 0.001] and 12-months [n = 6 studies, MD = -3.726, 95% CI (-6.347, -1.106), p = 0.005]. Additionally, CO2 laser therapy significantly decreased the Pelvic Floor Impact Questionnaire scores at 6 months [n = 2 studies, MD = -11.268, 95% CI (-18.671, -3.865), p = 0.002] and 12 months [n = 2 studies, MD = -10.624, 95% CI (-18.145, -3.103), p = 0.006]. Besides, CO2 laser therapy significantly decreased the Urogenital Distress Inventory-6 scores at 3 months [n = 2 studies, MD = -21.997, 95% CI (-32.294, -11.699), p < 0.001], but not at 6 months [n = 3 studies, MD = -3.034, 95% CI (-7.357, 1.259), p = 0.169]. Lastly, CO2 laser therapy significantly increased the Vaginal Health Index Score at 6 months [n = 2 studies, MD = 2.826, 95% CI (0.013, 5.638), p = 0.047] and 12 months [MD = 1.553, 95% CI (0.173, 2.934), p = 0.027]. Conclusion: CO2 laser therapy improved the SUI-related symptoms in women. To obtain solid conclusions, future studies should be well-designed with standardized settings, consistent therapeutic protocols, and long-term follow-up periods.

Blastocyst morphology has no relationship with serum ß-hCG levels and live birth rates once pregnant.

OBJECTIVE: What is the role of blastocyst morphology on day16 ß-hCG serum levels and pregnancy outcomes among patients who conceived through IVF cycles with single fresh Gardner's scored blastocyst transfers. STUDY DESIGN: A retrospective cohort study conducted at a single academic fertility center between January 2013 and December 2017. A total of 643 pregnancies were included in the study. RESULTS: The patients were divided into 5 groups according to Gardner's blastocysts grade of the ICM and the TE (grade), and into 4 groups according to blastocyst Gardner's degree of blastocoel expansion (stage). No significant differences were found between the different morphologic groups and day16 ß-hCG serum levels, clinical pregnancy rates and live births. A weak significant correlation was observed between Gardner's blastocysts grade and day 16 ß-hCG (Correlation Coefficient r= -0.098, p = .014) this correlation remained significant after controlling for confounders. (r= -0.099 p = . 013). A weak significant correlation was observed between Gardner's stage and day 16 ß-hCG (Correlation Coefficient r = 0.086, p = 0.029) this correlation lost significance after controlling for confounders. (r = 0.055, p = 0.340). When evaluating predictors of live birth using multivariate logistic regression, blastocyst grade (p = 0.33) and stage (p = 0.65), at transfer, were not associated with live births, when controlling for confounding effects. CONCLUSION: Once the patient conceives after IVF with single blastocyst, none of the morphological parameters have a strong impact on the day16 serum level of ß-hCG. Among women who conceived, blastocyst grade and stage were not associated with live births.
