Death resulting from ruptured cerebral artery aneurysm: 219 cases   总被引:1,自引:0,他引:1  
To characterize the demographics of ruptured cerebral artery aneurysm as a cause of death and to examine the effect of improved diagnostic and therapeutic techniques on the incidence of sudden death associated with the condition, the authors reviewed 219 autopsies performed at the Dallas County Medical Examiner's Office between 1977 and 1997 in which the cause of death was ruptured cerebral artery aneurysm. Ruptured cerebral artery aneurysms accounted for 1.5% of 15,033 natural deaths and 0.4% of all deaths (45,492) followed by autopsy during this period. The majority (56%) of cases occurred in females, with Caucasian females composing the largest group (38%). Seventy-seven percent of cases occurred in individuals between the ages of 31 and 70 years, with the highest concentration in the 41- to 50-year decade (29%). The most common location for ruptured aneurysms was the middle cerebral artery distribution (39%). Multiple aneurysms occurred in 22 (9.1%) cases. Other factors, such as medical history, coexisting disease, symptoms, activity at onset of symptoms, survival time, and toxicology results are also presented. Compared with literature reports before 1980, when ruptured cerebral artery aneurysms were reported as the cause of death in approximately 4% to 5% of sudden natural deaths, the results of this study suggest that despite improved diagnostic and therapeutic techniques during the past two decades, morbidity and mortality from ruptured aneurysms remain a significant health problem.  相似文献

To extend research linking pubertal timing and adolescent health outcomes, this study examines boys’ pubertal timing and subsequent interpersonal success and health behaviors in mid adulthood. Past research has shown that boys’ pubertal timing is associated with both positive and negative developmental outcomes in the short term, and so it is unclear how pubertal timing is consequential for adjustment across the long term. Data from 460 boys from the Terman Life-Cycle Study were examined over a 39-year period to relate age of pubertal onset to later marital success, career success, and adult health behaviors. Boys who reached puberty earlier than their peers achieved greater success in their careers and experienced more satisfaction in their marriages. Early-developing boys were not found to be more likely than their peers to smoke cigarettes or drink alcohol as adults. Findings are discussed in terms of the importance of pubertal timing for life-span development.Keiko Taga is a doctoral student at the Department of Psychology at University of California, Riverside.

This article examines the stability of street-level bureaucrats' negative perceptions regarding a newly implemented managed care system on quality of care and service delivery in a publicly funded behavioral health care system. Overall findings indicate that the generally negative perception of managed care did not differ between staff in the two programs, indicating a weak effect on attitudes of frontline workers. More proximal variables to the caregiver, such as service type and job title, show more influence on attitudes. The conclusion discusses the implications of these findings for practicing administrators and academic researchers.  相似文献

There is little professional consensusregarding the effect of economic conditionson House Elections. We argue that recentwork still uses the paradigm of Party toorganize their data and tests. Given thatrecent developments in the theory ofcongress emphasize the paradigm ofIncumbency, we investigate the empiricalrelevance of that competing paradigm. Weshow that (1) Incumbency matters in a purePresidential Party Model of HouseElections, (2) Presidential Party mattersin a pure Incumbency Model, (3) Once bothParty and Incumbency are accounted for,economic conditions exert a highlysignificant and temporally stable influenceon House elections, (4) Return Rates aremore affected by economic fluctuations thanare Vote Shares, and (5) Not allPresidential Party incumbents face the samedegree of electoral accountability foreconomic fluctuations.  相似文献

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs—adolescence and young adulthood—in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.  相似文献
