老年结直肠癌的治疗   总被引:1,自引:0,他引:1  
老年患者占结直肠癌患者的70%,因此老年人是结直肠癌的主要患病人群。为了提高结直肠癌治疗的总体疗效,我们应当特别关注老年性结直肠癌的治疗。以往,手术治疗和化疗的应用随着年龄的增高而明显减少。我们一直以为老年人手术和化疗的效果不令人满意。近期的研究改变了这一认识。证据表明辅助化疗和姑息性化疗对一般情况良好的老年人是有效而安全的。即使存在一些与年龄相关的基础疾病的老年结直肠癌患者仍然能从合理的治疗方案中获益。所以我们尚有许多工作需做,以提高老年性结直肠癌患者的疗效。腹腔镜下结肠癌根治术是对老年人安全有效的手术技术。我们期待随着经腔道的内窥镜手术技术的发展,将来会使老年性结直肠癌患者受益。  相似文献

城市“空巢”家庭特征分析   总被引:10,自引:0,他引:10  
在城市化进程中,家庭空巢化正在成为一个热点问题。空巢老人是老年人中有独特需要的群体,极易产生各种身心问题。影响家庭空巢的因素很多,既有来自人口内部结构的因素.也有来自观念、社会、经济等方面的原因,并且在人口、经济、生理、休闲方式上有着独特的特征。空巢家庭的养老问题有着很大风险,因此养老模式的探讨也是一个值得关注的问题。  相似文献

情节记忆是个体对特定时间,特定地点所经历的特定事件的记忆.主观报告情节记忆下降是主观记忆减退老年人最典型的表现.与健康对照组老年人相比, 主观记忆减退老年人情节记忆下降的速率更快, 罹患老年性痴呆的风险更高, 但其情节记忆加工的脑机制尚不明确.前人研究提示, 主观记忆减退老年人在外在记忆行为尚未出现损伤的情况下, 其大脑情节记忆相关脑区的神经活动已经出现异常.探究主观记忆减退的记忆神经环路关键节点和路径的异常, 揭示神经环路在老年痴呆发生发展中的变化规律, 对深入理解老年痴呆的发病机制有重要的科学意义.同时, 主观记忆减退老年人作为特殊的记忆损伤群体, 对其神经环路的深入探究, 也必将为揭示人类记忆的神经机制做出独特的贡献.  相似文献

抑制不足理论认为老年人抑制能力不足, 易受干扰信息的影响, 阻碍对目标词的检索, 故比年轻人有更多舌尖现象。实验1操纵抑制通达子功能探讨其在老年人舌尖现象中的作用, 采用2(干扰条件:有、无)×2(年龄组:老年、年轻)的混合设计, 相比于无干扰条件, 干扰条件下舌尖现象年龄差异变得更大, 表明老年人舌尖现象和通达功能有关。实验2操纵抑制删除子功能, 采用2(是否激活干扰:是、否)×2(年龄组:老年、年轻)的混合设计, 不激活干扰条件下舌尖现象年龄差异不显著, 而激活干扰条件下舌尖现象年龄差异显著, 舌尖现象随龄增多与删除功能不足有关。通达和删除功能不足是老年人舌尖现象增多的重要原因。  相似文献

Abstract This study was designed to obtain an understanding of the subjective well - being ( SWB ) status amongChina‘s urban elderly, and to find out the major factors that could influence the status in question. Our survey wasconducted of 233 urban elderly individuals, and the data was statistically examined by multiple regression analysiswith the results that: 1 ) The SWB of China‘ s urban elderly was relatively high as only 4.5 96 of all respondentsconsidered themselves unhappy or very unhappy; 2) Major factors that had an influence on SWB included economicresource, mobility, age and social support; and 3 ) Five demographic variables accounted for 18.6 96 of the variancein SWB, which was slightly higher than that of foreign findings. It is concluded that financial security, active par-ticipation in physical and social activities, and social support are necessary for the improvement of the SWB of the el-derly.  相似文献

New Horizons Bands are wind and percussion bands designed for both novice and former musicians over the age of 50. This article describes the Iowa City, Iowa, program from the director's observations and from excerpted comments by participants. Not only does the band program fulfill musical aspirations, but it also provides meaningful interpersonal relationships for the adult learners and their families, the college-aged instructors, and the director.  相似文献

Emotional disturbances following brain damage have been frequently reported in the literature. However, systematic investigation of these disorders and their specific causes were not common until the last 30 years. However, the number of research studies into this area remains slight compared to the voluminous literature on the cognitive effects of brain injury. The completed research has fallen into 3 major areas: (1) The study of clients with localized brain injuries to evaluate whether the site of the injury predicts the emotional reactions; (2) the effect of time poststroke on personality changes; and (3) the relation of neuropsychological deficits to emotional changes. This paper provides a comprehensive review of the research that has been completed in this area with elderly subjects along with an analysis of the current state of the knowledge in this area. Future directions for research to further our understanding are discussed.  相似文献

The concept of guardianship, its associated principles, distinctions, and articulation of the legal needs of the elderly are introduced via a review of well-canvassed criticisms of Canadian guardianship legislation. Claims that the reformed legislation of Alberta, Quebec, and British Columbia represent models of adequate adult guardianship compared with traditional (archaic lunacy) law are examined. This paper argues that these renovated models exhibit a dubious normative advance over traditional legislation. Specifically, the normative presuppositions of the reformed legislation, such as, restriction to an autonomy-paternalism framework, and the norms of the liberal individual and state, obscure important issues in at least two key areas which challenge the models' assumptions; namely, assessment and legal competence and assessment and need. The development of guardianship laws and of social arrangements that are more responsive to the life experiences of the elderly requires critical re-articulation of the nature of individuals and their communities.  相似文献

The Multiple Affect Adjective Check List (MAACL) has been found to have five first-order factors representing Anxiety, Depression, Hostility, Positive Affect, and Sensation Seeking and two second-order factors representing Positive Affect and Sensation Seeking (PASS) and Dysphoria. The present study examines whether these first- and second-order conceptions of affect (based on R-technique factor analysis) can also account for patterns of intraindividual variability in affect (based on P-technique factor analysis) in eight elderly women. Although the hypothesized five-factor model of affect was not testable in all of the present P-technique datasets, the results were consistent with this interindividual model of affect. Moreover, evidence of second-order (PASS and Dysphoria) and third-order (generalized distress) factors was found in one data set. Sufficient convergence in findings between the present P-technique research and prior R-technique research suggests that the MAACL is robust in describing both inter- and intraindividual components of affect in elderly women.This paper is based on the doctoral research of the first author and was partially supported by the National Institute of Aging Grant T32 AC 00048-12 to The Pennsylvania State University and a Grant-in-Aid of Research from Sigma Xi, The Scientific Research Society. The authors wish to thank John R. Nesselroade for his helpful comments on an early draft of this paper.  相似文献

Speaking disorders frequently result in serious consequences for mentally impaired elderly people. Two examples are presented illustrating the modification of both excess and deficit rates of talking via differential reinforcement procedures. Two men exhibiting verbal disorders severe enough to impair social interactions and lead to possible nursing home placement were treated by teaching their spouses to reinforce positive and ignore undesired verbal responses. Problem behaviors were reduced sufficiently to permit continued home care, and alternative positive behaviors were increased. These findings suggest that verbal behavior of the mentally impaired elderly can be affected by applying systematic consequences and can be modified by relatively simple procedures. These procedures provide an alternative to the negative effects of labels associated with either aversive or deficient verbal behaviors, promote more positive activities, and enable continued residence at home. Further, this research provides support for the generality of the utility of training spouses to serve as behavior therapists for the impaired elderly.  相似文献
