Age and total and free prostate-specific antigen levels for predicting prostate volume in patients with benign prostatic hyperplasia

Objectives: To investigate the predictive values of free prostate-specific antigen (fPSA), total PSA (tPSA) and age on the prostate volume.

Methods: The data of 2148 patients with lower urinary tract symptoms were analyzed retrospectively. The patients who had transrectal ultrasonography guided 10 core biopsies owing to the findings obtained on digital rectal examination and presence of high PSA levels (PSA?=?2.5–10?ng/dl), and proven to have BPH histopathologically were included in the study. Age, tPSA, fPSA and the prostate volumes (PV) of the patients were noted.

Results: One thousand patients that fulfilled the inclusion criteria were included in the study. The PV of the patients were significantly correlated with age, tPSA and fPSA (p?r?=?0.307, p?r?=?0.382, p?r?=?0.296, respectively). On linear regression model, fPSA was found as a stronger predictive for PV (AUC?=?0.75, p?p?p?=?0.013).

Conclusions: Although tPSA is an important prognostic factor for predicting PV, the predictive value of fPSA is higher. PV can easily be predicted by using age, and serum tPSA and fPSA levels.

Class, gender and time poverty: a time-use analysis of British workers' free time resources

Free time, that is, the time that remains at one's own discretion after conducting daily work and personal care activities, has been previously recognized as a 'primary good' and an important welfare resource that provides opportunities for participation in social life and leisure. However, recent years have witnessed an increasing preoccupation with the phenomenon of time poverty, drawing attention to the distribution of free time and its relationship to structural and family circumstances. In this article we propose a novel approach to the measurement of time poverty and document its occurrence amongst British workers. In line with previous literature, a conceptualization of time poverty as a relative lack of free time resources vis-à-vis other members of the community is adopted. However, unlike previous empirical studies, we investigate the differential configuration of time poverty on weekdays and weekend days, alongside indicators of the quality of free time, taking into account insights from theoretical and empirical work within the field of the sociology of time. Our analysis of the 2000 UK Time Use Survey highlights class and gender inequalities that have been missed by previous measurement approaches and demonstrates that, overall, working women experience multiple and more severe free time constraints, which may constitute an additional barrier for their leisure and social participation.     

孙中山的人学思想及其现实意义

孙中山的人学思想产生于19世纪末20世纪初的近代中国,是在其"致力国民革命四十年,求中国之自由平等"的斗争实践中逐渐形成的。它内涵丰富、意蕴深远,涉及互助人性论、民生观、自由平等观、"生元"说以及人生观等方面的内容。探讨发掘孙中山的人学思想中蕴含的积极合理成分,在当代无疑具有重要的现实意义。     

哲学､哲学研究及其与政治的关联——兼论《第179号“科伦日报”社论》的当代意义

《第179号“科伦日报”社论》中,马克思关于哲学的本质是理论与实践的高度统一、哲学研究是求真、哲学必然要介入社会政治等问题的看法,既是马克思在整个《莱茵报》时期的思想基础,是破解马克思当时碰到的“三件难事”的发生及其往后的思想转变的钥匙;也是马克思哲学的本质特点,有助于理解和把握马克思主义的真精神及作为“实证科学”的历史唯物主义的本性.它对于我们当前的马克思主义研究在研究立场和方式上亦有重要启示意义.因此,该社论不能被简单当成马克思思想过渡时期的作品,而应引起学界的应有重视.     

基于福建自贸区视角的涉外旅游人才培养研究

福建自贸区的建成给福建旅游业带来了新的挑战和机遇。随着福建对外开放程度的逐步提高,福建省对涉外旅游人才的要求将进一步严格,涉外旅游从业人员的素质也随之成为关注的焦点。从福建省高校涉外旅游人才培养的现状来看,存在结构不合理、专业化程度低、无法满足市场需求等问题,应从人才集聚战略、人才培养目标、师资队伍建设等方面采取措施。

浅说希腊哲学中的意志与自由

在西方哲学史中,自由意志理论是一个非常重要的思想资源,它起源于古希腊时期。那时对意志自由思想的探索尚处在朦胧阶段,哲学家们并未对该问题进行专门的研究,只有一些简单粗糙的规定散见于不同哲学派别的学说中,但正是这些粗陋的规定,为整个西方意志自由思想的发展奠定了基础。     

责任的哲学基础

责任分为“事后责任”与“事前责任”,“事后责任”是作为对某一过去行为“负责”的责任,而“事前责任”则是作为将来关心某人某事的道德性或法律性义务的责任。说一个人在事前或事后负有责任,这要涉及到哲学中的一些老话题,这些话题包括自由意志、积极和消极的责任、团结是否原则上受个人或群体契约之限制等问题。一个社会中责任的分配,是一个利己主义和利他主义相互矛盾运动的复杂变化过程。
