Little is known about the social networks of homeless youth in emerging adulthood despite the importance of this information
for interventions to reduce health risks. This study examined the composition of social networks, and the risks and supports
present within them, in a random sample of 349 homeless youth (33.4% female, 23.9% African American, 17.7% Hispanic) between
the ages of 18 and 24. Social network members who were met on the street were among the most likely to be perceived as engaging
in risky sex, as well as to engage in substance use with the youth. Youth were more likely to count on relatives and sex partners
for support compared to other network members, but they also were more likely to use substances with sex partners and perceived
them as engaging in risky sex. Interventions may need to recognize the importance of intimate relationships during the developmental
stage of emerging adulthood by enhancing supportive bonds and reducing substance use and risky sex in these relationships. 相似文献

Thousands of barium enemas are performed in the United States each year without incident. Occasionally complications arise, only a few of which are fatal. Perforation is the most frequent serious complication of this procedure. Two instances of fatal perforation, one colonic and the other vaginal, are described, and the relevant literature is reviewed. 相似文献

Two college students developed symptoms of poisoning following ingestion of a salt solution during a college physiology laboratory exercise. Symptoms included nausea, vomiting, diarrhea, and altered consciousness. The ingested solution was identified as isotonic buffered saline containing sodium azide in a concentration of 1.0 g/L. The solution was commercially prepared for instrumentation use only and was used inadvertently for the exercise instead of freshly preparing sodium chloride in water. One student drank three sips of the solution and survived. The other student drank 700 to 800 mL and over several days became progressively ill, suffering myocardial damage and cardiac dysrhythmias, and, finally, died. Toxicologic studies confirmed the presence of azide in an antemortem urine sample from the deceased. Sodium azide is an uncommon but potent poison which can cause serious illness and death. 相似文献

Age-related variation in the interstitial tissues of the cardiac conduction system; and autopsy study of 230 Han Chinese 总被引:3,自引:0,他引:3
The amount of fatty and fibrous tissues in 230 Han Chinese who died of noncardio-vascular diseases has been studied by a semi-quantitative method and analysed by chi-square test. The results have shown some consistency. Generally, in the sino-atrial node (SAN), fibrosis and fatty influtratin appear only after 40 years of age and increase one grade with every 20 years. The atrio-ventricular node (AVN) showed fatty change after 30 years of age and fibrosis appeared after 60. In the His bundle (HB), fatty infiltration and fibrosis appear after 40 years. The left bundle branch (LBB) showed similar changes. The appearance of fibrosis in the AVN seems to be later than that reported by Lev. 相似文献

Mountain climbing is a popular recreational activity with a growing number of participants and associated fatalities. To define the characteristics of these fatal incidents and the typical autopsy findings in the victims, we reviewed the autopsy and investigative findings of all fatalities that occurred on Mount Rainier from 1977 through 1997. A total of 50 deaths occurred in 29 separate incidents. Fifty-eight percent of accident victims died as the result of a fall; another 34% died as a result of an avalanche. The incidents leading to death occurred at an average altitude of 3652 m (11,977 feet); range, 2073 to 4389 m (6800-14,400 feet). The average age of the victims was 31.2 years (range, 17-55 years), and 47 of the 50 were men (94%). Bodies were not recovered in 13 cases (26%). Autopsies were performed in 30 of the remaining 37 cases. At autopsy, the cause of death was ascribed to multiple injuries in 12 cases (40%), isolated head and neck injuries in 7 cases (23%), and chest injuries in 1 case (3%). Asphyxia and hypothermia were the cause of death in 8 cases (27%) and 2 cases (7%), respectively. The frequency of specific injuries is presented by anatomic region. The unique autopsy and investigative features of mountaineering deaths are discussed. 相似文献

According to the laws of negligence, jurors' liability decisions are to be influenced by the defendant's conduct, but not by the severity of the plaintiff's injuries. We conducted a jury simulation study to assess whether jurors reason in this manner. We manipulated the conduct of the defendant (reasonable, careless) and the severity of injuries to the plaintiff (mild, severe) in a simulated automobile negligence case. Jurors completed predeliberation questionnaires, deliberated to a verdict, and answered postdeliberation questionnaires. The defendant's conduct had a strong impact on liability judgments, but evidence related to injury severity also had an effect, albeit smaller. We analyze these findings in the context of various cognitive and motivational theories. 相似文献
