The association between endocrine therapy and common pelvic floor disorders including urinary incontinence has rarely been evaluated. We examined urogenital and sexual side effects among women with a breast cancer diagnosis, comparing endocrine therapy users to nonusers.Methods: Urogenital and sexual symptoms were self-reported during the enrollment interview within the University of North Carolina Cancer Survivorship Cohort. Tumor characteristics and endocrine therapy use were collected from medical and prescription records. We calculated multivariable prevalence ratios (PR) and 95 % confidence intervals (CI) for the association of endocrine therapy (versus no endocrine therapy) and urinary incontinence, overall and by therapy type (tamoxifen or aromatase inhibitors). PROMIS Sexual Function and Satisfaction domain scores were compared across endocrine therapy groups.Results: Among the 548 women with a breast cancer diagnosis, 49 % received endocrine therapy. Overall, 18 % of women reported urinary incontinence symptoms. We observed no association between urinary incontinence and endocrine therapy use overall (PR = 0.97; 95 % CI 0.67, 1.43), tamoxifen (PR = 1.20; 95 % CI 0.74, 1.96), or aromatase inhibitors (PR = 0.89; 95 % CI 0.55, 1.42), compared to no use. Approximately 55 % of women were sexually active. Sexual function scores did not vary according to endocrine therapy use, although urinary incontinence was associated with lower satisfaction scores (p = 0.05).Conclusions: Our findings demonstrate a high prevalence of urinary incontinence after breast cancer diagnosis similar to the overall prevalence in older U.S. women, and this did not vary strongly according to use of endocrine therapy.","PeriodicalId":35798,"journal":{"name":"自动化学报","volume":"38 1","pages":"1325-1332"},"PeriodicalIF":2.3,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5835969/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78926151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The costate and constraint multiplier estimates for the proposed method are rigorously derived by comparing the discretized optimality conditions of an optimal control problem with the Karush-Kuhn-Tucker conditions of the resulting nonlinear programming problem from collocation. The distinctive advantages of the proposed method over other pseudopsectral methods are the good numerical stability and computational efficiency. In order to achieve this goal, the barycentric Lagrange interpolation is substituted for the classic Lagrange interpolation in the state approximation. Furthermore, a simple yet efficient method is presented to alleviate the numerical errors of state differential matrix using the trigonometric identity especially when the number of Chebyshev-Gauss points is large. The method presented in this paper has been taken to two optimal control problems from the open literature, and the results have indicated its ability to obtain accurate solutions to complex constrained optimal control problems.</div>","PeriodicalId":35798,"journal":{"name":"自动化学报","volume":"41 10","pages":"Pages 1778-1787"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1874-1029(15)30004-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"56928798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the existing semi-supervised clustering algorithm, this method uses the must-link and cannot-link constraints. Instead of using the idea that the instances with must-link constraints are pre-clustered before agglomerating with the others, this method employs a more general and reasonable process. Firstly, must-link and cannot-link constraints are expanded to compose a constraints closure. Then, a standard agglomeration instructed by cannot-link constraints is processed. During this procedure, the must-link and cannot-link are dynamically updated according to the intermediate clustering results. This updating process guarantees the validity of the final results. The fundamental advantage of this method is omitting the pre-clustering process of the instances with must-link constraints. This modification ensures that data points gain a more reasonable agglomeration order, which may result in a significant improvement on the clustering results. This research also introduces an implementation of this model based on Ward0s method, leading to the C-Ward algorithm. The experimental analyses on both Artificial simulated datasets and real world datasets show that this method is much better than the others.","PeriodicalId":35798,"journal":{"name":"自动化学报","volume":"41 1","pages":"1253-1263"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67550484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
