    Optimal Cutpoint Estimation with Censored Data

    Get PDF
    We consider the problem of selecting an optimal cutpoint for a continuous marker when the outcome of interest is subject to right censoring. Maximal chi square methods and receiver operating characteristic (ROC) curves-based methods are commonly-used when the outcome is binary. In this article we show that selecting the cutpoint that maximizes the concordance, a metric similar to the area under an ROC curve, is equivalent to maximizing the Youden index, a popular criterion when the ROC curve is used to choose a threshold. We use this as a basis for proposing maximal concordance as a metric to use with censored endpoints. Through simulations we evaluate the performance of two concordance estimates and three chi-square statistics under various assumptions. Maximizing the partial likelihood ratio test statistic has the best performance in our simulations

    The EU is facing crucial external challenges for its present and future stability, security and prosperity. The instability in the Middle East, terrorism, the global warming and environmental change issue, the world’s growing economic globalization and its outsiders, or the political and economical competition with the Chinese and Indian giants leading to increasingly rival partnerships must be properly understood and assessed in the full extend of their implications and consequences, and addressed by appropriate policies. But the future of EU’s role as an international actor is also being decisively shaped today by the challenges the EU faces from its Eastern neighborhood which are likely to have fundamental long term economical and political consequences on the EU. These challenges directly influence EU’s stability, security and prosperity and ability to be an international actor capable of identifying its interests, and successfully pursuing or protecting them.Keywords: foreign, relations, enlargement, world, actor.

    In the current document we are referring to the existing data concerning the impact that benzene - which is one of the most important components of different types of fuels - has on Bucharest and on its inhabitants. We are also trying to present possible solutions to this serious problem which is affecting our lives. We have to take into account that the level of pollution is directly related with cancer mortality. And one of the most common causes for cancer, especially for professional cancers, is benzene – the most important aromatic hydrocarbons.environment protection, pollution, industrial ecology

    The present study wishes to bring to the attention of the reader the alarming impact that the common benzene molecule has on the environment, with unimaginable implications on the human being. Although it has a great economic importance, being used in many industries, specialists are underlining the fact that benzene is extremely toxic, even in small quantities. In this document there are mentioned, under the form of case studies, the risks that those working in the presence of benzene fumes have to face.benzene fumes, air pollution, environmental effects

    Introduction: The aim of this study is to identify the way in which childbirth in general, and the delivery method in particular, influenced the maternal psychosocial status and the perception upon birth during postpartum. Material and method: We conducted a cohort type 2 prospective study. We included patients who had given birth at “Bucur” Maternity of Hospital “St. John” Bucharest from the 1st of January 2017 until the 1st of January 2018. Results: The majority of the patients (21.05%) who chose to give birth vaginally assigned the maximum degree (10) to the difficulty of birth. The patients who gave birth through cesarean section experienced the feeling of sadness in a higher percentage than those who gave birth vaginally (30.52% versus 21.05%). Among the patients who were in favor of having more children, 85.45% preferred the same delivery method. All the patients who gave birth vaginally wished to have other children using the same method, while 81.4% from the patients who gave birth through cesarean section were in favor of more children. Conclusion: The patients’ perception of childbirth was a subjective parameter. Further studies with standardized questionnaires should be applied for more reliable results

    The psychosocial impact of vaginal delivery and cesarean section in primiparous women

    The aim of this study was to identify how the method of delivery and birth experience interfere with maternal psychological status early after puerperium. We conducted a prospective study on 148 women after puerperium from November 2017 to January 2018 in Bucur Maternity Hospital. Women that delivered vaginally mobilized in the first 6 hours in 73.7% of the cases, but for cesarean section after 12- 24 hours in 43.6% of the cases. Women described good support from the obstetrician in 58.1% of the cases. 90.5% of the women reported that the method of delivery did not have an impact on infant care and 73% had no lactation problems. The majority described little trauma, in 32.4% of the cases. 70.3% of the patients reported that they wanted to have more children and 59.5% of them desired the same method of delivery. Negative feelings, lactation, and taking care of the baby were not influenced in this study by the method of delivery, but by prematurity of birth and the complications that women experienced at birth
