A Combination of Artificial Intelligence with Genetic Algorithms on Static Time-Lapse Images Improves Consistency in Blastocyst Assessment, An Interpretable Tool to Automate Human Embryo Evaluation: A Retrospective Cohort Study.

Background: In recent times, various algorithms have been developed to assist in the selection of embryos for transfer based on artificial intelligence (AI). Nevertheless, the majority of AI models employed in this context were characterized by a lack of transparency. To address these concerns, we aim to design an interpretable tool to automate human embryo evaluation by combining artificial neural networks (ANNs) and genetic algorithms (GA).

External validation of a fully automated evaluation tool: a retrospective analysis of 68,471 scored embryos.

Objective: To externally validate a fully automated embryo classification system for in vitro fertilization (IVF) treatments.

Design: Retrospective cohort study.

Setting: Clinic.

The effect of male factors on embryo morphokinetics: a retrospective analysis of 2726 blastocysts.

Purpose: Male infertility may influence fertilization rates, embryo morphology, and implantation rates in in vitro fertilization (IVF) cycles. Oocyte competence plays a major role in embryo development, but there is a limited understanding of the connection between sperm quality, embryo development, and morphokinetic parameters using donor oocytes. The study evaluated if sperm quality may influence the morphokinetic parameters in IVF cycles.

The international transportation of frozen embryos does not affect IVF outcomes.

Purpose: The regulated transportation of cryopreserved human embryos resulting from assisted reproduction treatments offers opportunities for patients undergoing embryo transfer in other regions/countries. However, the principal concern for fertility clinics is maintaining unaltered embryo quality to ensure satisfactory clinical outcomes. The aim of the study was to evaluate the efficacy of the transportation process comparing the survival rate and competence of transported embryos to embryos produced and transferred on-site, in frozen embryo transfer cycles.

Deep learning enables robust assessment and selection of human blastocysts after in vitro fertilization.

Visual morphology assessment is routinely used for evaluating of embryo quality and selecting human blastocysts for transfer after in vitro fertilization (IVF). However, the assessment produces different results between embryologists and as a result, the success rate of IVF remains low. To overcome uncertainties in embryo quality, multiple embryos are often implanted resulting in undesired multiple pregnancies and complications.

Foreign body aspiration in adults and in children: advantages and consequences of a dedicated protocol in our 30-year experience.

Background: Foreign body (FB) inhalation is a potentially life-threatening emergency also in clinically stable patients as the situation could worsen at any moment. There is varying opinion regarding the urgency for removal of inhaled FBs, and there are no guidelines in the literature. The aim of our study was to present our experience with FB aspiration in children and adults from 1993, when we introduced our Thoracic Endoscopy Service with the availability "on call" of a bronchologist 24 hours a day, 7 days a week, defining a dedicated protocol together with our anaesthesiologists for prompt intervention in this situation.

The outcome of intracytoplasmic sperm injection using occasional spermatozoa in the ejaculate of men with spermatogenic failure.

Purpose: Men with spermatogenic failure so profound that they are considered as having nonobstructive azoospermia occasionally have spermatozoa in the ejaculate. We compared intracytoplasmic sperm injection outcomes following the injection of ejaculated or surgically retrieved spermatozoa from these men.

Materials And Methods: A study was performed of intracytoplasmic sperm injection cycles with no spermatozoa on initial semen analysis and 100 or fewer following centrifugation (cryptozoospermia).

The combination of polar body and embryo biopsy does not affect embryo viability.

Background: The biopsy of both polar bodies and a blastomere from the same embryo was investigated as an approach aimed at increasing the quantity of DNA available for genetic analysis in preimplantation embryos.

Methods: In 113 cycles, preimplantation genetic diagnosis (PGD) was performed for aneuploidy: 19 cycles underwent polar body biopsy, 32 cycles had both polar body and blastomere biopsy done, and the remaining 62 cycles underwent blastomere biopsy. The chromosomal analysis was performed in a two-round fluorescence in situ hybridization (FISH) protocol with probes specific for the chromosomes X, Y, 13, 15, 16, 18, 21 and 22.
