High ferritin levels have been found to be associated with non infectious as well as infectious causes including tuberculosis. This is one case report of 41 year old male who presented with cough with expectoration. The patient had Multi drug resistant tuberculosis (MDRTB) and type 2 diabetes mellitus. The laboratory findings showed Iron 280 μg/dl, Total iron binding capacity (TIBC) 61 μg/dl, and ferritin 92,945 ng/ml which indicates that iron is an essential nutrient for the survival of the pathogen Mycobacterium tuberculosis.  相似文献

The aim of the study was to examine whether a cognitive-behavioral self-help program was effective in improving depressed mood and anxiety in people with acquired deafness. Participants were 45 persons with acquired deafness, randomly allocated to the Cognitive-Behavioral Self-help (CBS) group or the Waiting List Control (WLC) group. Depression and anxiety scores were assessed at three measurement moments: at pretest, immediately after completion of the intervention (posttest), and again 2 months later (follow-up). To evaluate the effectiveness of the program, repeated measures analyses of covariance were performed. The results showed that depression and anxiety symptoms in the CBS group significantly improved after completion of the program, compared to the WLC group. There was no relapse from posttest to follow-up. It was concluded that a cognitive-behavioral self-help intervention could be an effective tool to reduce symptoms of depression and anxiety in people with acquired deafness.  相似文献

This study investigates the strategies and assumptions that college students entering an introductory physical geology laboratory use to interpret topographic maps, and follows the progress of the students during the laboratory to analyze changes in those strategies and assumptions. To elicit students’ strategies and assumptions, we created and refined a topographic visualization test that was administered before and after instruction to 26 students during the first semester of the study and to 92 students during the second semester. To more deeply understand how students think about and conceptualize topographic maps, we focused on eight individual students who were interviewed about their pretest and posttest answers as well as videotaped during three laboratory sessions. We found that even students who claim never to have worked with topographic maps often perform impressively on their pretests by making useful assumptions about symbolic topographic information. Some students, however, begin with less productive assumptions that may be unfamiliar to some instructors (e.g., thinking that the spacing of contour lines indicates elevation instead of slope). Initial success should not be misinterpreted, however, as an integrated understanding of topographic maps. Only in posttest interviews do most students express explanations integrating multiple normative assumptions. In addition to highlighting the strategies and assumptions that college students use to interpret topographic maps, we outline the implications of these findings for the design of learning objectives, curricular activities, and assessments for topographic lessons in introductory college geology courses and the training of future geoscientists.  相似文献

This essay reads the NBC drama The West Wing against the cultural anxieties and ambivalences about the contemporary presidency, arguing that the program presents a powerful and meaningful “presidentiality,” a discursive construction of the presidency with ideological and rhetorical relevance. Specifically, The West Wing mimetically captures a view of the presidency, offering, in the process, a romantic vision of the institution that reflects the postmodernity of U.S. politics and the uncertainty that pervades questions of heroism and hierarchy at the turn of the twenty‐first century. In part, the political drama disrupts images of traditional power politics, presenting a more chaotic, inclusive, and communal portrayal of the presidency. Against this narrative backdrop, however, we contend that the program situates its postmodern rendition of presidentiality within a cathartic portrayal of the presidency, relying on conservative demarcations of presidential leadership ordered by commitments to intellectualism, militarism, masculinity, and whiteness.  相似文献
