轻度认知功能障碍与颈动脉狭窄的相关性研究

为了探讨颈动脉狭窄与轻度认知功能障碍(MCI)的关系,选取轻度认知功能障碍病例89例,健康对照组100例,全部行颈动脉彩超检查及简易智能状态量表(MMSE),蒙特利尔认知量表(MoCA),临床痴呆量表(CDR),日常生活能力量表(ADL),汉密尔顿抑郁量表(HAMD)测评.结果发现轻度认知功能障碍组颈动脉狭窄发生率明显高于对照组,左侧发生率明显高于右侧.其中随着狭窄的严重程度增加,患者在延迟回忆、视空间与执行功能、计算力与注意力、语言能力方面评分显著下降.从这一结果可以看出轻度认知功能障碍与颈动脉狭窄密切相关.     

Meta‐stereotypes,Social Image and Help Seeking: Dependency‐Related Meta‐stereotypes Reduce Help‐Seeking Behaviour

People who need help can be reluctant to seek it. This can be due to social image concerns. Here, we investigate if these concerns may be prompted by a salient negative meta‐stereotype: the belief that one's group is judged negatively by another group. Specifically, we researched group members' help‐seeking behaviour in the context of a dependency‐related meta‐stereotype. In a two‐condition study (N = 45), we manipulated participants' belief that their national group was judged dependent by a significant out‐group. We then examined their subsequent help‐seeking behaviour on a real‐world task. Participants whose social identity as a group member was salient showed greater reluctance to seek help when the meta‐stereotype was made prominent compared with when it was not. This suggests that, in a context where social image and social identity concerns are relevant, group members are willing to sacrifice the possibility of accessing needed help in order to avoid confirming a negative stereotype of their group. The implications of these results for helping transactions and community development are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Presleep Suggestion Related to a Phobic Object: Successful Manipulation of Reported Dream Affect

Twenty-four female subjects with a strong dislike of snakes slept for four nonconsecutive nights in the laboratory. They were divided into four groups of six, each group receiving a different presleep suggestion on Nights 3 and 4. On Nights 2, 3, and 4, before sleep, the subjects saw but did not have to touch a live snake and their dreams were collected for each REM period. The results showed that, when compared with the subjects who received the negative affect suggestions, subjects who received positive affect suggestions had significantly higher levels of positive emotions in their dreams, rated their own dreams as more pleasant, and had significantly lower levels of anxiety, sadness, and aggression. These results support the hypothesis that presleep suggestion can be an effective technique in influencing the affective dimension of the dream.     

Exposure to Repetitive Tasks Induces Motor Changes Related to Skill Acquisition and Inflammation in Rats

The authors elucidate exposure-response relationships between repetitive tasks, inflammation, and motor changes with work-related musculoskeletal disorders. Using a rat model of reaching and handle pulling, they examined effects of performing a high-repetition, low-force (HRLF); low-repetition, high-force (LRHF); or high-repetition, high-force (HRHF) task (2 hr/day, 3 days/week, 12 weeks) on reach rate and force, percentage of successful reaches, duration of participation, and grip strength. Reach rate and reach force improved with HRLF, and percentage success increased in all groups in Week 9, and in HRLF and HRHF in Week 12, indicative of skill acquisition. Duration and grip strength showed force-dependent declines with task performance. A subset of HRHF rats received ibuprofen in Weeks 5–12. Ibuprofen significantly improved reach rate, reach force, and duration in treated rats, indicative of an inflammatory influence on reach performance. Ibuprofen improved percentage of successful reaches in Week 9, although this increase was not sustained. However, declines in grip strength, a nocifensive behavior, were not prevented by ibuprofen. Examination of cervical spinal cords of untreated and ibuprofen treated HRHF rats showed increased IL-1beta, an inflammatory cytokine, in neurons. These findings suggest that only a preventive intervention could have addressed all motor declines.     

False Memories in Individuals at Risk for Developing an Eating Disorder

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.     

Occupational Therapy Intervention in the Treatment of Alcoholics

The first section of this article will provide the rationale for all occupational therapists to learn extensively about the isease of alcoholism regardless of area of practice or type of agency where employed. It will offer su estions on how this learning can take place. The second section will take an historic look at occupational therapy literature documenting the use of occupational therapy in alcoholism rehabilitation from 1941 to the present. It will describe modalities currently being used by occupational therapists in alcoholism rehabilitation and discuss expansion of occupational therapy in this practice area.     

It is never the right time: How to help a mother to separate from her young child

In this paper I have described a short-psychotherapy treatment with a mother, a 3-year-old girl, and occasionally a father, over the difficulty in separating and settling down at nursery. The mother's unresolved mourning for the early miscarriage of her second baby was one important factor. She held on to the company and comfort provided by the little girl, who had become the vessel of maternal projections. Filled with Poppy's projections, the mother had also felt unable to withstand and process them. Mr Green was a conflictual element in the family, rather than a supportive husband and father, and Poppy's care and problems were left with the mother. Nine sessions unblocked the situation and allowed Poppy to settle down at a private nursery.
