Fibromuscular dysplasia is an idiopathic, nonatheromatous, and noninflammatory arterial disease that most commonly affects the renal and carotid arteries. We report a child with subarachnoid and ocular hemorrhage associated with an aneurysm due to fibromuscular dysplasia. Computed tomography following a witnessed collapse revealed diffuse subarachnoid hemorrhage and severe cerebral edema. An autopsy confirmed the radiographic findings and detected bilateral retinal hemorrhages, optic nerve sheath hemorrhages, and a ruptured saccular aneurysm due to focal fibromuscular dysplasia involving the intracranial right vertebral artery. This case documents a fatal subarachnoid hemorrhage in a child with an intracranial saccular aneurysm caused by fibromuscular dysplasia. The associated retinal hemorrhages are easily detected by postmortem monocular indirect ophthalmoscopy. 相似文献

The stability of ethanol in antemortem blood stored under various conditions has been widely studied. Antemortem blood samples stored at refrigerated temperature, at room temperature, and at elevated temperatures tend to decrease in ethanol concentration with storage. It appears that the stability of ethanol in blood exposed to temperatures greater than 38°C has not been evaluated. The case presented here involves comparison of breath test results with subsequent analysis of blood drawn at the time of breath testing. However, the blood tubes were in a refrigerator fire followed by refrigerated storage for 5 months prior to analysis by headspace gas chromatography. The subject’s breath was tested twice using an Intoxilyzer 8000. The subject’s blood was tested in duplicate using an Agilent headspace gas chromatograph. The measured breath ethanol concentration was 0.103 g/210 L and 0.092 g/210 L. The measured blood ethanol concentration was 0.0932 g/dL for both samples analyzed. Although the mean blood test result was slightly lower than the mean breath test result, the mean breath test result was within the estimated uncertainty of the mean blood test result. Even under the extreme conditions of the blood kit being in a refrigerator fire, the measured blood ethanol content agreed well with the paired breath ethanol test. 相似文献

Here we recount the experience of designing and executing an experimental summer course, at two different universities, that used popular films as primary texts to facilitate active learning about foreign policy. One course, designed for non–political science majors, was offered at the introductory level as credit/no credit; the other, intended for students with some background in political science and international affairs, was offered as an upper-level graded course. We held many of the films and readings constant across the two courses so that we could track similarities and differences between the courses. Here we report on why and how we designed the movie courses and what films and readings we used. We also evaluate the courses by drawing on the assessment mechanisms we employed as well as the students' evaluations. In short, although there are some important trade-offs involved in designing a movie course, we found the experience to be a positive one that prioritized student learning in a relaxed and novel way and achieved with some success the procedural and conceptual learning goals that we set forth. 相似文献

AbstractAgricultural interventions are thought to have the potential to improve nutrition, but little rigorous evidence is available about programmes that link the two. In this article, we study impacts of an integrated agricultural and nutritional biofortification project, the REU in Mozambique. We first provide evidence on dietary impacts of the programme and then examine impacts of the programme by participation intensity. Using OLS and IV techniques, we find that more intense participation in both project components led to larger impacts. The results therefore have important implications for refining the design of future projects attempting to link agricultural and nutrition interventions. 相似文献

Sensitive to the differences between centers and peripheries of knowledge production, this article explores how scholars in peripheral fields use knowledge from central fields to structure their academic careers. The article presents the findings of a case study of career choices of political scientists in Argentina. In order to understand the interplay between foreign knowledge and local strategies of enacting networks, this article focuses on the beginning of academic careers. At this early stage, political scientists in Argentina usually have to make a decision whether to stay in the country or go abroad for postgraduate education. Relying on positioning theory and recent developments in Science and Technology Studies, we identified two alternative positioning strategies. Those who stay in Argentina tend to hoard as many scholarly positions as possible, enacting local networks oriented towards teaching. Scholars who go abroad enact networks with international dimensions, in the process enrolling persons and objects, though not always successfully. Scholars with international experience tend to be research oriented, and they mention the working conditions abroad as particularly attractive. We show the extent to which these findings challenge some views of centers and periphery and highlight the active role of scholars in peripheral scientific fields. 相似文献

The contemporary global Aid for Trade (AfT) agenda emerged out of world trade negotiations and it could have profound implications for the future of development aid, depending on how it is interpreted. The European Union (EU) has recontextualised this global agenda to suit its own approach to trade and development; specifically a focus on regional integration, and free market but ‘pro-poor’ development models. AfT is ascribed a variety of purposes in EU texts and its use continues to adapt as the EU's trade and development policy evolves. Institutionally the AfT framework has not strongly affected EU processes, organisational structures or methodology. A study of the use of EU aid for regional integration reveals dissonance between its development relationship and its trade policies while a focus on pro-poor AfT reveals a lack of capacity. Overall, there are tensions not just between discourse and practice but between different discourses of the EU. 相似文献

Mapping the relationship of peer influences and parental/family characteristics on delinquency can help expand the understanding of findings that show an interdependence between peer and family predictors. This study explored the longitudinal relationship between two characteristics of peer relationships (violence and perceived popularity) with subsequent individual delinquency and the moderating role of family characteristics (cohesion and parental monitoring) using data from the Chicago Youth Development Study. Participants were 364 inner-city residing adolescent boys (54 % African American; 40 % Hispanic). After controlling for the effects of age and ethnicity, peer violence is positively related to boys’ delinquency. The effect of popularity depends on parental monitoring, such that the relationship between popularity and delinquency is positive when parental monitoring is low, but there is no relationship when parental monitoring is high. Furthermore, parental monitoring contributes to the relationship between peer violence and delinquency such that there is a stronger relationship when parental monitoring is low. Additionally, there is a stronger relationship between peer violence and delinquency for boys from high cohesive families. Findings point to the value of attention to multiple aspects of peer and family relationships in explaining and intervening in the risk for delinquency. Furthermore, findings indicate the importance of family-focused interventions in preventing delinquency. 相似文献

The relationship between family functioning and adolescents’ physical aggression has been well established, but whether these relationships might differ by ethnicity has received less attention. Ethnic variations may be important for targeting prevention programs to specific youth and families. This study examined the longitudinal relationship between family cohesion, parental monitoring, and physical aggression using data from the Multisite Violence Prevention Project sample of high-risk youth (elevated aggression). Participants were 1,232 high-risk middle school students (65 % male; 70 % African American; 15 % Hispanic). Meaningful demographic variations were identified. After controlling for intervention condition and study site, family cohesion was significantly negatively related to physical aggression, more so for Hispanic youth. Parental monitoring was negatively associated with physical aggression for African American youth only. Our findings point to the importance of developing culturally sensitive family interventions to prevent physical aggression in middle school. 相似文献
