s, resulting in EFS and female infertility. Our findings not only reveal the critical roles of ZP genes but also pave the way for the efficient genetic diagnosis of females with GEFS and oocyte degeneration.
To describe an unusual bilateral ureteral reimplantation due to endometriosis and to provide a flowchart of conservative decision making.

Video description of a case, demonstrating a step-by-step explanation of the decision planning and description of the surgical steps in a female patient with bilateral ureteral endometriosis who had previously undergone operation for bowel endometriosis, and who presented with extensive disease in the posterior compartment with no symptoms besides bilateral renal function disruption. The study was reviewed and approved by the Hospital Beneficência Portuguesa de São Paulo Institutional Review Board.

Tertiary referral center.

Deep infiltrating endometriosis involving the ureter has an incidence of 0.1% to 1%, normally affecting the lower one-third of its segment, up to 4 cm above the vesicoureteric junction. Bilateral ureteral involvement occurs in 9% of cases. The absence of specific symptoms makes the diagnosis of this condition challenging. Lumbar pain develops wheunctional disfunctions can be worse than the actual symptoms. In those situations, close surveillance is necessary.
To optimize a method of isolating extracellular vesicles (EVs) from uterine fluid and to characterize small non-coding RNAs (sncRNAs) from the EVs, with the goal of identifying novel receptivity-associated biomarkers.

Longitudinal study comparing sncRNA expression profiles from endometrial EVs.

University-affiliated, hospital-based fertility clinic.

Healthy volunteers with no history of infertility (Group A) and women receiving controlled ovarian stimulation (COS)-invitro fertilization treatment (Group B).

In Group A, EVs were isolated from uterine fluid obtained on luteinizing hormone (LH)+2 and LH+7 in one natural menstrual cycle. see more In Group B, EVs were isolated from uterine fluid obtained on human chorionic gonadotropin (hCG)+2 and hCG+7 in one COS cycle. RNAs extracted from EVs were profiled using next-generation sequencing.

Differential EV-sncRNAs between LH+2 and LH+7 (Group A), between hCG+2 and hCG+7 (Group B), and between pregnant and nonpregnant invitro fertilization cycles (Group B).

Ultracentrifugation was validated as the most efficient method to isolate EVs from uterine fluid. We identified 12 endometrial EV-sncRNAs (11 microRNAs and 1 piwi-interacting RNA) as receptivity-associated transcripts conserved in both natural and COS cycles. These sncRNAs were associated strongly with biological functions related to immune response, extracellular matrix, and cell junction. Within COS cycles, we also identified a group of EV-sncRNAs that exhibited differential expression in patients who conceived versus those who did not, with hsa-miR-362-3p most robustly overexpressed in the nonpregnant patients.

This study is the first to profile comprehensively sncRNAs in endometrial EVs from uterine fluid and identify sncRNA biomarkers of endometrial receptivity and implantation success.

To compare the changing peripheral levels of inflammation-related cytokine profile during a 9-day period after blastocyst transfer between women who did and did not conceive.

Prospective, observational, and longitudinal study.

University-affiliated hospital.

Forty-seven women with infertility who were undergoing single day-5 blastocyst transfer were recruited.

This prospective observational and longitudinal study on 47 women with infertility was performed in an invitro fertilization unit from December 2018 to August 2019. The amounts of a range of cytokines was measured on serial blood samples obtained during a 9-day period after blastocyst transfer.

Serial blood samples were obtained on the day of embryo transfer, and 3, 6, and 9 days afterward for measurement of serum interferon gamma (IFN-γ), tumor necrosis factor alpha, interleukin (IL)-2, IL-4, IL-10, IL-12, IL-13, IL-17, IL-18, and IL-22 using cytometric bead arrays; transforming growth factor beta 1 (TGF-β1) was measured using commercial enatory cytokine profile (increase IL-10 and TGF-β1) by 6 days after blastocyst transfer and the latter increase was sustained 9 days after blastocyst transfer, when pregnancy was confirmed.
Among women who conceived after blastocyst embryo transfer, there was a transient and modest increase in serum pro-inflammatory cytokine profile (IFN-γ and IL-17) 3 days after blastocyst transfer, which was followed by a switch to anti-inflammatory cytokine profile (increase IL-10 and TGF-β1) by 6 days after blastocyst transfer and the latter increase was sustained 9 days after blastocyst transfer, when pregnancy was confirmed.The fields of computer vision (CV) and artificial intelligence (AI) have undergone rapid advancements in the past decade, many of which have been applied to the analysis of intraoperative video. These advances are driven by wide-spread application of deep learning, which leverages multiple layers of neural networks to teach computers complex tasks. Prior to these advances, applications of AI in the operating room were limited by our relative inability to train computers to accurately understand images with traditional machine learning (ML) techniques. The development and refining of deep neural networks that can now accurately identify objects in images and remember past surgical events has sparked a surge in the applications of CV to analyze intraoperative video and has allowed for the accurate identification of surgical phases (steps) and instruments across a variety of procedures. In some cases, CV can even identify operative phases with accuracy similar to surgeons. Future research will likely expand on this foundation of surgical knowledge using larger video datasets and improved algorithms with greater accuracy and interpretability to create clinically useful AI models that gain widespread adoption and augment the surgeon's ability to provide safer care for patients everywhere.
