Compared with men, women are more likely to experience depression, and depression increases risk of morbidity and mortality in individuals with heart disease. Psychosocial interventions have been developed for depressed patients with heart disease; however, women's experience of chronic disease differs from men's and women may benefit from interventions tailored to address their difficulties. Spirituality and social roles have been related to depressive symptoms in other populations. To identify the relationship between depression and spirituality and social role performance (i.e., role concerns, role rewards and confidence in ability to fulfill roles) in women with heart disease, we assessed depressive symptoms, spirituality, social role functioning and medical history in 125 women with heart disease. After controlling for age and severity of medical conditions, spirituality, role confidence and role concerns were significantly associated with depressive symptoms. Consideration of spirituality and aspects of social role performance may be important when developing psychosocial interventions for depressed women with heart disease.  相似文献

Parkinson’s disease (PD) patients and healthy controls were administered a flanker task that consisted of the presentation of colored targets and distractors. Participants were required to attend to the center target and identify its color. The stimulus displays were either congruent (i.e., the target and flankers were the same color) or incongruent. The time between the onset of the flanker and the target color (the target onset delay) was either short or long. Results indicated that PD patients and controls did not differ in the magnitude of the flanker effect within individual trials in that both groups demonstrated a typical flanker effect at the short target onset delay and neither group demonstrated a flanker effect at the longer delay. However, when performance was examined on a trial-by-trial basis, PD patients demonstrated a slowing of reaction time relative to controls when having to make the same response across consecutive trials at longer inter-trial intervals when the flankers were incongruent across consecutive trials and the display on the second of two trials was incongruent. These results indicate that PD patients are impaired in inhibiting the distractors over an extended delay and that this deficit may impact motor responding in these patients, suggesting that the basal ganglia contribute to the interface of attention and action.  相似文献

用科学的证据和科学的管理指引心血管疾病的防治   总被引:4,自引:0,他引:4  
心血管疾病的防治不仅仅是心血管医生的问题,还是一个在循证医学引领下的一个全民生活方式改变的问题,也需要多学科相关专业的联盟,涉及心血管疾病治疗规范的形成与普及,对于疾病发生、发展各个阶段的科学管理更是冠心病的防治效果的重要保障。本文针对心血管病冠心病预防的具体实施,从几方面打开了一个全新的视野。  相似文献

心血管疾病的根本发病基础是动脉粥样硬化血栓形成,在这一认识基础上,近年来在冠心病预防方面提出了一系列颠覆性的概念,如“冠心病等危症“、“心血管疾病是代谢性血管疾病”等。本文以全新的理念、形象地描述、深入地分析,从动脉粥样硬化血栓形成的各个阶段,阐述了冠心病综合预防在控制冠心病过程中的重要作用。  相似文献

在心血管疾病临床试验中,替代指标常用于评价干预措施的疗效。但替代指标在心血管疾病临床试验中非常复杂,因此,心血管医生在解读和评价心血管疾病临床试验的结果时,应正确认识替代指标的内涵、应用背景及其局限性,同时,还应客观地评价相关替代指标的证据强度,以寻找最好的医学证据指导其临床决策和实践。  相似文献

肝豆状核变性(Wilson病)治疗策略的变革及思考   总被引:1,自引:0,他引:1  
评析肝豆状核变性(WD)当前的治疗方法,主要有低铜饮食,铜的螯合剂青霉胺及曲恩汀,锌制剂和四硫钼酸胺,肝移植。介绍WD治疗策略的变革:不再提倡驱铜疗法以去除堆积的铜,而是使血液中的游离铜离子浓度常态化以逆转铜中毒,并结合2007年《柳叶刀》WD治疗专家共识进行思考。最后,展望未来对WD可能的根治疗法,即基因治疗、肝细胞移植及现在可施行的肝移植。  相似文献

人类心身问题的研究一直是科学界关注的热点。近年来,国外学者将神经科学与哲学研究统一起来,集合两门学科的研究方法、综合双方的研究成果,以此来共同推进人类心身问题的研究,因此诞生了一门介于神经科学和哲学之间的独立学科,它有着学科交叉的研究领域和特殊的跨学科研究方法,这门学科就是神经哲学。  相似文献

A growing body of evidence suggests that a preclinical phase of Alzheimer's disease (AD) exists several years or more prior to the overt manifestation of clinical symptoms and is characterized by subtle neuropsychological and brain changes. Identification of individuals prior to the development of significant clinical symptoms is imperative in order to have the greatest treatment impact by maintaining cognitive abilities and preserving quality of life. Functional magnetic resonance imaging (fMRI) offers considerable promise as a non-invasive tool for detecting early functional brain changes in asymptomatic adults. In fact, evidence to date indicates that functional brain decline precedes structural decline in preclinical samples. Therefore, fMRI may offer the unique ability to capture the dynamic state of change in the degenerating brain. This review examines the clinical utility of blood oxygen level dependent (BOLD) fMRI in those at risk for AD as well as in early AD. We provide an overview of fMRI findings in at-risk groups by virtue of genetic susceptibility or mild cognitive decline followed by an appraisal of the methodological issues concerning the diagnostic usefulness of fMRI in early AD. We conclude with a discussion of future directions and propose that BOLD-fMRI in combination with cerebral blood flow or diffusion techniques will provide a more complete accounting of the neurovascular changes that occur in preclinical AD and thus improve our ability to reliably detect early brain changes prior to disease onset.  相似文献
