Rupture of aneurysms is a leading cause of death in the United States. Extensive biomechanical studies have shown that mechanical stress in aneurysm walls plays a critical role in the rupture of aneurysms. Highly elevated local stress and degraded aneurismal walls are believed to make aneurysms vulnerable to rupture [1–3]. Asymmetric aneurysms with irregular shape and wall thickness are vulnerable to rupture. Aneurismal arteries are often tortuous such as in the Loeys-Dietz syndrome [4], but the mechanism is unclear.

Building America: The Life of Benjamin Henry Latrobe is a biography of America’s first professionally trained architect and engineer. Born in 1764, Latrobe was raised in Moravian communities in England and Germany. His parents expected him to follow his father and brother into the ministry, but he rebelled against the church. Moved to London, he studied architecture and engineering. In 1795 he emigrated to the United States and became part of the period’s Transatlantic Exchange. Latrobe soon was famous for his neoclassical architecture, designing important buildings, including the US Capitol and Baltimore Basilica as well as private homes. Carpenters and millwrights who built structures more cheaply and less permanently than Latrobe challenged his efforts to establish architecture as a profession. Rarely during his twenty-five years in the United States was he financially secure, and when he was, he speculated on risky ventures that lost money. He declared bankruptcy in 1817 and moved to New Orleans, the sixth American city that he lived in, hoping to recoup his finances by installing a municipal water system. He died there of yellow fever in 1820. The themes that emerge in this biography are the critical role Latrobe played in the culture of the early republic through his buildings and his genius in neoclassical design. Like the nation’s political founders, Latrobe was committed to creating an exceptional nation, expressed in his case by buildings and internal improvements. Additionally, given the extensive primary sources available for this biography, an examination of his life reveals early American attitudes toward class, family, and religion.

The opioid epidemic has had disproportionate effects across various sectors of the population, differentially impacting various occupations. Commercial fishing has among the highest rates of occupational fatalities in the United States. This study used death certificate data from two Massachusetts fishing ports to calculate proportionate mortality ratios of fatal opioid overdose as a cause of death in commercial fishing. Statistically significant proportionate mortality ratios revealed that commercial fishermen were greater than four times more likely to die from opioid poisoning than nonfishermen living in the same fishing ports. These important quantitative findings suggest opioid overdoses, and deaths to diseases of despair in general, deserve further study in prevention, particularly among those employed in commercial fishing.

Many self-identified realist, liberal, and constructivist scholars contend that ideology played a critical role in generating and shaping the United States' decision to confront the Soviet Union in the early Cold War. A close look at the history reveals that these ideological arguments fail to explain key aspects of U.S. policy. Contrary to ideological explanations, the United States initially sought to cooperate with the Soviet Union, did not initially pressure communist groups outside the Soviet orbit, and later sought to engage communist groups that promised to undermine Soviet power. The U.S. decision to confront the Soviets stemmed instead from the distribution of power. U.S. policy shifted toward a confrontational approach as the balance of power in Eurasia tilted in favor of the Soviet Union. In addition, U.S. leaders tended to think and act in a manner consistent with balance of power logic. The primacy of power over ideology in U.S. policymaking—given the strong liberal tradition in the United States and the large differences between U.S. and Soviet ideology—suggests that relative power concerns are the most important factors in generating and shaping confrontational foreign policies.

Harlington, TX, July 19 (AP)—Federal agricultural officials say that the honey bees that killed an 82-year-old rancher last week were the Africanized variety known as "killer bees." "Our lab has confirmed that the bees are Africanized," said Kim Kaplan, a Spokeswoman for the Federal Department of Agriculture in Greenbelt, MD. Final autopsy results are not yet available, but the pathologist who did the autopsy listed the preliminary cause of death as acute fluid buildup in the lungs caused by insect stings. If the cause of death is confirmed, the rancher, Lino Lopex, would be the first person killed by Africanized bees in the United States since the aggressive variety migrated into Texas in 1990. Harlington, TX, in South Texas, is about 15 miles from the Mexican border. Mr. Lopez apparently tried to drive the bees out of a wall in an abandoned house by poking the hive with a stick wrapped with a burning burlap sack. He was dead on arrival at the hospital, with about 40 stingers still attached to his body, officials said.

IN ALL COUNTRIES for which there are vital statistics, accidents are a major cause of death and disability among children. In countries where the food supply is adequate and infectious diseases have been brought under control, accidents have become the leading cause of death in the age group 1 to 19 years. For example, in such countries as Australia, Canada, Sweden, West Germany, and the United States, more than one-third of all deaths in this age group are caused by accidents. The number of children who are injured by accidents fan exceeds the number who are killed. Although no accurate international figures are available, the Morbidity Survey conducted by the United States Public Health Service indicates that in the United States, for every child under 15 killed by accident, 1,100 children are injured severely enough to require medical attention or to be restricted in their activity for at least a day.

This article examines the emergence of a medical condition increasingly cited as a cause of death in fatality inquiries in Canada: Excited Delirium. Beyond the association between excited delirium and police use of electrical weapons known as Tasers, one common concern about the medical condition is whether or not it is “real.” Bypassing strictly realist or purely constructivist accounts, this article uses the conceptual language of historical ontology and science and technology studies to investigate how excited delirium is enacted within and between disparate medico-legal sites. Contributing to sociologies of death and dying and category formation, it attends to the textually-mediated practices of legal and medical experts in the United States and Canada that labour to produce excited delirium as a coherent medical condition rather than a “diagnosis of exclusion” reached upon autopsy.
