Association between long-term erectile dysfunction and biochemical recurrence after permanent seed I125 implant brachytherapy for prostate cancer. A longitudinal study of a single-institution

We aimed to investigate the predictive factor of erectile dysfunction (ED) in prostate cancer (PCa) patients who underwent low-dose permanent I¹²⁵ seed implant brachytherapy and to investigate if ED could represent a patient’s reported outcome measures (PROMs) of efficacy of BT and indirectly associated with biochemical recurrence free survival (BRFS). From 2000 to 2012, 176 consecutive patients with low-risk PCa underwent BT. ED was evaluated with the International Index of Erectile Function (IIEF-5). Cox regression analysis was performed to assess significant predictors of mild-to-severe ED and BRFS after BT, including covariates. The 10-year actuarial rate of ED was 66%. Subjects with severe ED had higher values of D90 (183.0 versus 177.0; p?p?p?p?=?0.20), while D90?≤?180?Gy independently predicted BCR (HR: 4.65; [95%CI: 1.25–17.34]; p?125 implant, but it is not associated with better BRFS.     

Changes in risky gambling prevalence among a New Zealand population cohort

Evidence suggests that problem gambling is an unstable state where gamblers move into and out of risk over time. This article looks at longitudinal changes in risky gambling and the factors associated with an increased risk (measured by the Problem Gambling Severity Index [PGSI]) in the current New Zealand context, which has experienced a doubling of the electronic gaming machine (EGM) market over the last two decades. Respondents from a nationally representative baseline sample (n = 2672) were recontacted two years later to assess changes in gambling behaviours. Among the 901 respondents reached at follow-up, average gambling risk increased over time, and the prevalence of those who had at least some level of gambling risk (i.e. low-risk or greater) more than doubled (from 4.7% to 12.4%). The majority (80.2%) of those who were at risk at follow-up had not been at risk at baseline. Multivariate linear regression analyses show that the predictors of low to moderate increased risk include Pacific ethnicity; high neighbourhood deprivation status; baseline frequent, continuous gambler type; baseline PGSI status; and playing EGMs. These findings highlight the need to develop theories of gambling addiction trajectories and to identify the earliest point along the trajectory where public health interventions should occur.     

多维视角下的老年人社会健康影响因素分析

采用全国老年人口健康状况调查项目2002年~2005年纵向数据作为研究样本,对中国老年人社会健康的影响因素进行多维分析。通过结构方程模型,在方法上解决了社会健康的多维性、抽象概念的定量分析和测量误差的问题。研究发现,经济社会因素是影响老年人社会健康的主要方面,其中老年人自身的经济条件是最重要的因素;心理健康是影响老年人社会健康的关键因素,其它因素通过心理健康对社会健康起间接作用;由于社会生活方式的改变,家庭因素对老年人社会健康的直接影响正在弱化,但是家庭因素对老年人社会健康的间接影响依然存在。     

幼儿撒谎行为的成因分析及对策研究

幼儿的撒谎行为是幼儿成长过程中面临的普遍问题，如果忽视这一问题，将会对幼儿的健康成长造成影响。对幼儿的撒谎行为教育者既不可漠不关心、任其发展，也不可过分斥责、大打出手。文章分析了影响幼儿撒谎行为的内外因素，提出了一系列矫正幼儿撒谎行为的有效策略，以促进幼儿身心健康发展。     

城乡困难家庭的求助网络及其政策启示

文章使用“城乡困难家庭调查”2014年跟踪数据，对我国城乡困难家庭的求助网络结构和家庭因素进行分析，发现：血缘和亲缘关系仍是我国城乡困难家庭最天然的帮扶网络，但官方社会救助系统的作用已超过民间系统，邻里朋友仅在血亲和官方系统失灵时起补充作用；基层治理结构对求助网络的城乡差异产生影响，流动人口家庭求助网络呈现多元均衡的特征，但面临官方救助系统的制度性缺失；人口规模、低保资格两个家庭因素对城乡困难家庭求助网络有显著影响。文章认为，应进一步发挥社会力量的作用，针对我国城乡困难家庭建立官民并举、多元协作的社会救助政策体系。     

外来人口社会融合中文化与制度的影响研究——以浙江省为例

外来人口流入易融入难。论文通过探索性因子分析,将外来人口社会融合的因素划分为经济、社会公共服务制度、文化三个层面。浙江省是工业大省,外来人口在经济因素方面对社会融合的影响不大;而社会公共服务制度方面却对社会融合影响较大,应该为他们提供无差别的公共服务,解决制度方面的障碍;文化方面对社会融合的影响最大。     

对外汉语教学中的文化因素导入

语言是文化的重要载体,也是其重要组成部分,语言交际能力与社会文化因素有着密切的关系,并且受文化因素的制约。分析了对外汉语教学中文化因素的重要性,阐释了在文化导入过程中应该遵循的原则,并就如何在对外汉语教学中进行文化因素导入进行了理论探讨,以期望促进对外汉语教学的改革和深化。     

Identifying radon-prone building typologies by marginal modelling

Radon is a naturally occurring decay product of uranium known to be the main contributor to natural background radiation exposure. It has been established that the health risk related to radon exposure is lung cancer. In fact, radon is considered to be a major leading cause of lung cancer, second only to smoking. In this paper, we identified building typologies that affect the probability of detecting indoor radon concentration above reference values, using the data collected within two monitoring campaigns recently conducted in Northern Italy. This information is fundamental both in prevention, i.e. when the construction of a new building is planned and in mitigation, i.e. when a high concentration detected inside buildings has to be reduced. A spatial regression approach for binary data was adopted for this goal where some relevant covariates on the soil were retrieved by linking external spatial databases.

民族地区乡村经济行为模式、动机体系及其变迁研究

民族地区乡村经济中的主导经济行为模式至少存在四种类型。民族地区人们的经济行为大致有三种基本的动机体系。改革开放以来,有五种主要因素在改变着这些经济动机体系和行为模式,一是乡(镇)政府、具有准政府性质的村集体组织以及其他各种组织的推动、示范和劝导作用,二是体制改革的推动或压力,三是文化移入的诱导或冲击,四是内部创新行为的出现,五是特定文化传承的激活。
