This retrospective study enrolled 845 singleton pregnant patients with placenta previa from two hospitals. They were allocated into a training cohort (n = 403), a testing cohort (n = 174), and the external validation cohort (n = 268). Univariate and multivariate regression analyses were employed to select clinical variables (p < 0.05), which were subsequently utilized to develop 11 machine learning prediction models. The area under the receiver operating characteristic curve (AUC), decision curve analysis (DCA), accuracy (ACC), sensitivity (SEN), and specificity (SPE) were used to evaluate the performance of the models. Besides, SHapley Additive exPlanations (SHAP) was used to interpret the role and effectiveness of variables in the predictive model. Three machine learning models with the best predictive performance were combined into a Prediction Ensemble Classifier through voting. The Gradient Boosting Machine demonstrated the best predictive performance. In the validation cohort, AUC of the Gradient Boosting Machine model is 0.810(95% CI 0.754-0.865), ACC was 0.765(95% CI 0.716-0.813), SEN was 0.613(95% CI 0.513-0.723), while these values of the Prediction Ensemble Classifier were 0.813(0.756-0.871), 0.806(0.757-0.854), and 0.480(0.375-0.597), respectively. The importance of SHAP variables in the model, ranked from high to low, is as follows: d-dimer, ultrasound diagnosis of placenta accreta spectrum, neutrophils, prothrombin time, and platelets.

A total of fifty-six patients with PCOS were randomly assigned to receive 800 mg/day of resveratrol or placebo for 60 days.

Additionally, secondary outcomes included measuring the expression of genes associated with OS responses (Manganese superoxide dismutase (Mn-SOD), catalase (CAT), and uncoupling protein 2 (UCP2)), as well as the expression of UCP2 protein in granulosa cells. Compared with the placebo group, resveratrol reduced MDA and conversely significantly increased total thiol (P = 0.6694 and P = 0.0318, respectively) in FF.

The present study aimed to investigate the risk factors associated with resistance to first-line single-agent chemotherapy. This retrospective cohort includes patients diagnosed with low-risk GTN who were treated with single-agent chemotherapy using methotrexate and actinomycin.

Patients aged 40 or older had about 7 times higher odds of treatment resistance than younger patients. Choriocarcinoma increased the odds by 5.5 times, and each 1 cm increase in tumor size raised the odds by 53%. In patients with WHO scores of 0-4, each additional year of age increased resistance odds by 6%, and choriocarcinoma raised it by 7.5 times. In both groups, lung metastasis increased the chance of resistance threefold. Increased age, larger tumor size, increase βhCG level and start of treatment with MTX, increase the likelihood of resistance to first-line chemotherapy in the 0-6 score and in the subgroup with a 0-4 score. Future prospective studies are necessary to validate new models Until then, clinicians should be aware of the limitations of the current system and consider individualized clinical judgment.</p>","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144966581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
