This study tested the extent to which coached participants can simulate the neural responses of participants with posttraumatic stress disorder (PTSD) when they are presented with signals of fear. Functional magnetic resonance imaging (fMRI) was used to study blood oxygenation level-dependent signal during the presentations of fearful and neutral faces under both conscious and nonconscious (masked) conditions. Participants comprised 12 patients with PTSD and 12 trauma-exposed controls who were instructed to simulate PTSD. During conscious fear processing, simulators showed greater activation in the left amygdala and medial prefrontal cortex (MPFC) than PTSD participants. By contrast, during nonconscious processing, PTSD participants had greater MPFC activation than simulators. These findings suggest that coached simulators produce a profile of ‘over-responding’ to fear when controlled conscious processing is possible, but are not able to simulate the exaggerated medial prefrontal responses observed in PTSD participants under conditions of nonconscious processing. 相似文献

Identification of 3,4-methylenedioxy-N-methylamphetamine (MDMA, ecstasy) in five cases of intoxication using nuclear magnetic resonance (NMR) spectroscopy of human urine is reported. A new water suppression technique PURGE (Presaturation Utilizing Relaxation Gradients and Echoes) was used. A calibration curve was obtained using spiked samples. The method gave a linear response (correlation coefficient of 0.992) over the range 0.01–1 mg/mL. Subsequently, quantitation of the amount of MDMA present in the samples was performed. The benefit and reliability of NMR investigations of human urine for cases of intoxication with MDMA are discussed. 相似文献

Adolescent nutritional and psychological patterns and risk for the development of an eating disorder
Gloria R. Leon Ph.D. Professor Director of Clinical Psychology Cheryl L. Perry Ph.D. Associate Professor Director of Community Health Education Carolyn Mangelsdorf M. A.

A group of 256 female and 248 male adolescent students were assessed regarding nutritional practices and psychological attitudes associated with the development of eating disorders. While the majority showed adequate nutritional practices, there was a high prevalence of dieting and the consumption of low-calorie foods among the girls. For boys, there was no relationship between a strong desire for thinness and restriction of foods high in calories; boys tended to report that hunger and positive affective states were related to overeating. A risk factor conception of nutritional and psychological precursors to the later development of an eating disorder was discussed.This research was supported in part by a Biomedical Research Support Grant to Dr. Cheryl Perry. 相似文献

Childhood disruptive behaviors can be precursors to later deviance. To verify the efficacy of karate, a complex psychomotor activity that enhances self-regulation and executive skills, as an intervention for externalizing behaviors, 16 children, ranging in age from 8 to 10 years, and meeting diagnostic criteria for oppositional defiant disorder were studied. Eight were randomly assigned to a 10-month Wa Do Ryu karate program, whereas 8 children received no intervention. The children were assigned to a larger karate class, composed of typically developing youngsters. Three domains of temperament--intensity, adaptability, and mood regulation--were measured at the beginning and the end of the training period in all 16 participants. A significant improvement in temperament scale scores was measured in the karate group for all tested items compared to controls. Karate, when properly taught, can be a useful adjunct in multimodal programs aimed at externalizing behavior reduction. 相似文献

Private-public partnerships are increasingly seen as an important mechanism for improving community health. Despite their popularity, traditional evaluations of these efforts have produced negative or mixed results. This is often attributed to weak interventions or an insufficient period of time to observe an impact. This study examines two additional possibilities--the need for a well-articulated shared vision and the governance and management capabilities of the partnership itself. We conducted a midstream process evaluation of twenty-five community partnerships associated with the Community Care Network (CCN) Demonstration Program. We examined how the roles of a common shared vision, strong governance, and effective management influence a partnership's ability to achieve its objectives. The findings, based on both qualitative and quantitative analyses, underscore the importance of membership organizations' perceived benefits and costs of participation and management capabilities to the partnership's progress toward a vision. Based on the qualitative data, six key governance and management characteristics are identified that separate the top performing partnerships from the lowest performing ones. We explore the implications of this research for future evaluations of public-private community health partnerships. 相似文献
