Background::In vitro fertilization (IVF) has emerged as a transformative solution for infertility. However, achieving favorable live-birth outcomes remains challenging. Current clinical IVF practices in IVF involve the collection of heterogeneous embryo data through diverse methods, including static images and temporal videos. However, traditional embryo selection methods, primarily reliant on visual inspection of morphology, exhibit variability and are contingent on the experience of practitioners. Therefore, an automated system that can evaluate heterogeneous embryo data to predict the final outcomes of live births is highly desirable. Methods::We employed artificial intelligence (AI) for embryo morphological grading, blastocyst embryo selection, aneuploidy prediction, and final live-birth outcome prediction. We developed and validated the AI models using multitask learning for embryo morphological assessment, including pronucleus type on day 1 and the number of blastomeres, asymmetry, and fragmentation of blastomeres on day 3, using 19,201 embryo photographs from 8271 patients. A neural network was trained on embryo and clinical metadata to identify good-quality embryos for implantation on day 3 or day 5, and predict live-birth outcomes. Additionally, a 3D convolutional neural network was trained on 418 time-lapse videos of preimplantation genetic testing (PGT)-based ploidy outcomes for the prediction of aneuploidy and consequent live-birth outcomes.Results::These two approaches enabled us to automatically assess the implantation potential. By combining embryo and maternal metrics in an ensemble AI model, we evaluated live-birth outcomes in a prospective cohort that achieved higher accuracy than experienced embryologists (46.1% vs. 30.7% on day 3, 55.0% vs. 40.7% on day 5). Our results demonstrate the potential for AI-based selection of embryos based on characteristics beyond the observational abilities of human clinicians (area under the curve: 0.769, 95% confidence interval: 0.709–0.820). These findings could potentially provide a noninvasive, high-throughput, and low-cost screening tool to facilitate embryo selection and achieve better outcomes. Conclusions::Our study underscores the AI model’s ability to provide interpretable evidence for clinicians in assisted reproduction, highlighting its potential as a noninvasive, efficient, and cost-effective tool for improved embryo selection and enhanced IVF outcomes. The convergence of cutting-edge technology and reproductive medicine has opened new avenues for addressing infertility challenges and optimizing IVF success rates.

Objective To construct a MRI-based radiomics nomogram for predicting the Cyelin-Dependent Kinase Inhibitor 2A/B(CDKN 2A/B)homozygous deletion status in patients with isocitrate dehydrogenase(IDH)-mutant astrocytoma.Methods A total of 200 patients with IDH-mutant astrocytoma(103 CDKN 2A/B homozygous deletion and 97 CDKN 2A/B non-homozygous dele-tion)were enrolled in a training cohort(n=140)and a test cohort(n=60).A total of 1 946 features were respectively extracted in tumor edema area and tumor parenchyma area,and 3 892 features were extracted in overall tumor area.All features were extracted from T2 fluid attenuated inversion recovery(T2 FLAIR)and T1 WI contrast enhancement sequences.The t test and the least absolute shrinkage and selection operator(LASSO)model were used to select radiomics features,and a radiomics nomogram was constructed by using age,gen-der and the above radiomics features.Results The t test concluded that the overall tumor radiomics signature had the best perform-ance[area under the curve(AUC):training cohort=0.951,test cohort=0.779]and the radiomics nomogram had a good ability to pre-dict the CDKN 2A/B homozygous deletion in IDH-mutant astrocytoma.The clinical usefulness of the nomogram in predicting the CDKN 2A/B homozygous deletion was further confirmed by decision curve analysis(DCA).Conclusion The nomogram combined with age,gender,and the radiomics features provides a clinically useful approach to predict the CDKN 2A/B homozygous deletion and facilitated MRI-based clinical decision-making in patients with IDH-mutant astrocytoma.

Objective:To explore the effect of staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair.Methods:From January 2021 to December 2022, convenience sampling was used to select 73 patients who underwent arthroscopic rotator cuff repair in the Department of Hand Surgery at Affiliated Hospital of Nantong University as participants. According to the random number table method, patients were divided into a control group ( n=36) and an observation group ( n=37). Control group received routine rehabilitation nursing, while observation group received staged rehabilitation nursing. The University of California, Los Angeles (UCLA) Shoulder Rating Scale score, American Shoulder and Elbow Surgeons (ASES) Rating Scale score, Constant-Murley Shoulder Scale score, and complications during rehabilitation were compared between two groups of patients before and six months after intervention. Results:Six months after surgery, both groups showed an increase in UCLA scores and ASES scores compared to before the intervention ( P<0.05), and the scores of observation group were higher than those of control group, with statistical differences ( P<0.05). Six months after surgery, the Constant-Murley Shoulder Scale scores for daily life and shoulder range of motion in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05). During the rehabilitation period, the incidence of complications in observation group was lower than that in control group with a statistical difference ( P<0.05) . Conclusions:Staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair shows significant effects and can effectively promote patient recovery.
