BACKGROUND: Clozapine is the gold standard in treatment of treatment-resistant psychotic patients. We know little about the effects of compulsory treatment in patients unwilling to accept the necessary treatment. AIMS: To assess the effectiveness, tolerability and safety of compulsory treatment with clozapine (CTC). METHOD: A cohort of 17 consecutive patients given compulsory treatment with clozapine were rated retrospectively by their treating psychiatrists on the basis of their case notes. RESULTS: CGI-S decreased significantly over time until last observation after a mean of more than 15 months. No patient deteriorated as measured by CGI-I. At last observation as many as ten of the 11 patients still on clozapine were classified as much to very much improved. The degree of custodial restriction at last observation showed improvement in 11 patients and no change in six. No serious adverse events were observed. CONCLUSION: A trial of compulsory treatment with clozapine showed this treatment to be feasible, effective, safe and well tolerated.  相似文献

Haplotype data were obtained from a sample of 173 unrelated male individuals from Cartagena (Colombia), for 16 Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10). No shared haplotypes were observed, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in Cartagena. Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of Iberian origin.  相似文献

强制汽车责任保险中的保险人承担的是何种责任,学术界一直争论不休。实际上,保险人的责任应为合同义务,保险人责任一词本身并不科学。而产生这一用语并导致诸多争端的正是我国刚实施不久的《机动车交通事故责任强制保险条例》中的相关规定。解决这一问题的办法是借鉴他国先进立法,将侵权制度与责任保险制度明确分离。  相似文献

Interstate relations are highly interdependent: a change in relations between a pair of states can impact the relationship each of those states has with third parties, as well as relations among those third party states. This is particularly salient in cases where emerging security threats have the potential to destabilize existing patterns of interstate behavior. While the interdependent nature of states’ strategic responses to varied security challenges is often discussed and theorized in the international relations (IR) literature, it is less frequently modeled empirically. We present an approach for analyzing state relations that takes into account higher-order dependencies in the position of states within a network. We apply the approach to a unique context: diplomatic relations between Middle East and North African (MENA) states during a period in which the Islamic State of Iraq and the Levant (ISIL) becomes a significant destabilizing force in the region. We find that the emergence of ISIL dramatically reshaped the region’s politics, improving relations among the region’s major powers while worsening relations for the states facing territorial threats from the group.  相似文献

This work deals with the study of the evolution and the historical experience of Spanish journalism in the context of decades of transition between the nineteenth and twentieth centuries. From the selection of the most relevant cases and the examination of tracking, or not, of models and European patterns of the reference press, singularities and analogies of the historical evolution of the Spanish journalism model may be seen – an evolutionary model fully registered within the framework of Western Europe and in one of its most fruitful phases: the origins and first development of the mass media. Therefore, the following trilogy of reference media is selected covering specified time periods: El Imparcial, Madrid, 1867–1933; La Vanguardia, Barcelona, 1881; and ABC, Madrid, 1903.  相似文献

塞浦路斯金融危机的发生,对俄罗斯经济是一次深刻的教训,使其一方面启动经济去离岸化进程,另一方面筹划构建自己的离岸金融中心。俄罗斯因经济发展长期受到金融支持不足的困扰,希望利用离岸金融中心,获得经济发展所需的资金支持。这也是梅德韦杰夫总理提出的"造血行动"的一部分。本文运用SWOT分析方法,梳理俄罗斯离岸金融发展的优劣态势,得出内外渗透型模式是俄罗斯建立离岸金融中心初期的最佳选择的结论,并简要提出俄罗斯经验对中国的若干启示。  相似文献

In this paper, we focus on the relationship between parents’ education and activities aimed at increasing the human capital of children (for example, educational childcare). Using time use surveys from Mexico, Peru, Ecuador, and Colombia we find that in Mexico, Peru, and Colombia the level of education of both father and mother has a positive association with the time devoted to educational childcare, while in Ecuador only fathers’ level of education has a positive association with father’s time devoted to educational childcare. Furthermore, we find that the time devoted to educational childcare by parents is positively related in all four countries.  相似文献
