In order to cooperate with voluntary screening programs aimed at the surveillance of the HIV epidemic in Finland, we have studied medicolegal autopsies for HIV antibodies since 1986 using an enzyme immunoassay on postmortem sera. The investigation covered 47.4% and 39.2%, respectively, of all deaths under the age of 65 years in the metropolitan areas of Helsinki and Turku--two cities on the densely populated southern coast of Finland from which most HIV infections have thus far been detected. Nine HIV-positive cases (0.12%) were detected among the 7305 medicolegal autopsies tested in 1986 to 1990. This figure is higher than the prevalence of 0.01 to 0.03% in voluntary screening programs for the general population would suggest. Seven of our cases had previously tested positive, and two were previously unknown cases, indicating that people at high risk are clustered in the medicolegal autopsy series. Of the six cases in an early stage of infection, three committed suicide suggesting the importance of HIV-screening in suicide cases in tracing symptomless HIV carriers. Five of the cases were detected in 1990, a year when the number of new HIV infections had more than doubled compared to the previous two years. This suggests that testing of medicolegal autopsies as surrogate tests for the population gives useful information even in low-prevalence areas like Finland. Such testing has none of the ethical problems of many other back-up surveys, and may be particularly sensitive to early changes in epidemiology.  相似文献

Current research suggests that a husband's substance abuse is correlated with severity of physical abuse and the woman's decision to leave a violent situation. Often, only the battered woman's report of abuse is available. This study compares women's reports of their partners' substance use/abuse with their partners' report using a brief measure of polydrug and alcohol abuse, the Substance Abuse Subtle Screening Inventory (SASSI) and the Conflict Tactics Scale (CTS). Data were analyzed for 25 recovery couples and 25 nonrecovery couples. The correlations for all 50 couples between the male's reported use and the female's report of her partner's use on the SASSI and the CTS were significant on all but one of the CTS scales. They ranged on SASSI from .73 to .33 and from .31 to .06 on the CTS. This suggests that the SASSI and possibly the CTS could be used as valuable tools for assessing women's reports of their partner's substance use/abuse.  相似文献

The psychological assessment battery is an integral part of the selection process used to select patrol officer applicants. Unlike all other procedures used in the selection process, the psychological assessment has not been adequately validated. The purpose of this study was an attempt to provide validation data for a psychological assessment battery. The battery consisted of the Nelson-Denny, Shipley-Hartford, MMPI, and the Motivational Analysis Test (MAT). Performance measures included various measures of training academy performance and field training performance. A stepwise regression and MANOVA/Discriminant Analysis indicated that the psychological tests did predict performance, although an exact predictive equation could not be developed due to the high intercorrelations between predictor variables. This research was sponsored in part by a grant from the School of Applied Arts and Technology, Southwest Texas State University.  相似文献
