Oxycodone is a potent semi-synthetic narcotic prescribed for the management of pain. Previous investigators have reported that the abuse of oxycodone is most frequently seen in conjunction with the abuse of other drugs, although fatalities have been reported with oxycodone alone. We undertook a retrospective review of cases investigated by the Palm Beach County Medical Examiner's Office in which postmortem toxicologic studies indicated the presence of oxycodone. A total of 172 consecutive cases were studied, including 18 in which death was attributed to oxycodone toxicity, 117 to combined drug toxicity, 23 to trauma, 9 to natural causes and 5 to another drug or drugs. The postmortem blood concentrations of oxycodone overlapped among the groups. The mean blood oxycodone concentration among the cases of oxycodone toxicity was 0.69 mg/L, combined drug toxicity 0.72 mg/L and trauma 0.62 mg/L. Concentrations were lower in cases of deaths attributed to natural causes and to another drug or drugs (mean each 0.087 mg/L). Benzodiazepines, detected in 96 cases, were the most common co-intoxicants in the cases of combined drug toxicity, followed by cocaine, which was found in 41. The most frequently encountered benzodiazepine was alprazolam. This study confirms that deaths in which oxycodone is a factor are most commonly cases of combined drug toxicity. The high incidence of alprazolam as a co-intoxicant has not been previously recognized.  相似文献

In the "post-genomic" age of biomedical research, researchers often wish to utilise collections of human tissue. This type of research raises many ethical and legal issues and anyone wishing to use such collections is faced with an enormously complex set of regulatory requirements, many of which are still ambiguous, reflecting ongoing ethical and legal debate. Whilst there is no way of entirely avoiding such regulatory complexity and ambiguity, conceptual frameworks can assist those who wish to use, administer, authorise and generate policy on tissue banking research. Two conceptual frameworks are described here: a taxonomy of tissue banking practices, aimed at assisting those who need to ensure that tissue banks meet ethical and legal requirements; and a "syncretic" approach to policy-making, for those who wish to generate new policy, or streamline existing policy relating to tissue banking research.  相似文献

Derived from comparative approaches in both qualitative and quantitative research, the current study describes a simple exploratory technique for the multivariate analysis of categorical data. This technique is referred to as the conjunctive analysis of case configurations. After describing the logic and underlying assumptions of this conjunctive method, it is applied and illustrated in the study of the federal sentencing of drug offenders. The relative value of this conjunctive approach for purposes of exploratory data analysis and its overall utility as a method for confirmatory research are also discussed.

A structural equation model based on social cognitive theory was used to predict relationship violence from young adolescents' knowledge, self-efficacy, attitudes, and alternative conflict strategies (n = 143 male and 147 female grade 7-9 students). A direct causal effect was supported for violence-tolerant attitudes and psychologically aggressive (escalation/blame) strategies on physical violence against dating partners and friends. Knowledge and self-efficacy contributed to using reasoning-based strategies, but this reduced violence only in boys' friendships. Knowledge reduced violence-tolerant attitudes, thus reducing escalation/ blame and physical violence. Attitudes toward male and female dating violence (ATMDV and ATFDV) were indicators of general attitudes toward violence among non-dating students but ATFDV affected physical violence and ATMDV affected psychological aggression for both dating boys and girls.  相似文献

This article examines Nepalese forestry governance from gender perspectives. We argue that gendered institutional norms and values are associated with forest-governing institutions, such as forest bureaucracies, shaping the nature, and extent of women’s involvement in decision-making processes in the Nepalese forest bureaucracy. Studies on Nepalese forestry reveal that substantial progress has been made in forming policies and initiating activities for including women in forestry governance of Nepal; however despite this, gendered dynamics create difficulties for women to enter and progress in the forestry profession, thereby creating gendered employment territories through institutional, legislative, normative, and infrastructural measures.  相似文献
