In vitro activities of posaconazole (Sch 56592) compared with those of itraconazole and fluconazole against 3,685 clinical isolates of Candida spp. and Cryptococcus neoformans

Posaconazole is a new investigational triazole with broad-spectrum antifungal activity. The in vitro activities of posaconazole were compared with those of itraconazole and fluconazole against 3,685 isolates of Candida spp. (3,312 isolates) and C. neoformans (373 isolates) obtained from over 70 different medical centers worldwide. The MICs of the antifungal drugs were determined by broth microdilution tests performed according to the National Committee for Clinical Laboratory Standards method using RPMI 1640 as the test medium. Posaconazole was very active against all Candida spp. (MIC at which 90% of the isolates were inhibited [MIC(90)], 0.5 microg/ml; 97% of MICs were < or =1 microg/ml) and C. neoformans (MIC(90), 0.5 microg/ml; 100% of MICs were < or =1 microg/ml). Candida albicans was the most susceptible species of Candida (MIC(90), 0.06 microg/ml), and Candida glabrata was the least susceptible (MIC(90), 4 microg/ml). Posaconazole was more active than itraconazole and fluconazole against all Candida spp. and C. neoformans. These results provide further evidence for the spectrum and potency of posaconazole against a large and geographically diverse collection of clinically important fungal pathogens.     

Caspofungin activity against clinical isolates of fluconazole-resistant Candida

A total of 7,837 clinical isolates of Candida were tested against fluconazole, and 351 resistant (fluconazole MIC >/=64 micro g/ml) isolates were identified (4% of the total tested). All fluconazole-resistant isolates were inhibited by caspofungin at concentrations that can be exceeded by standard doses (MIC at which 90% of the isolates were inhibited, 1 micro g/ml; 99% of the MICs were 相似文献   

师范院校贫困新生与非贫困新生心理健康状况的比较

目的:比较师范院校贫困新生与非贫困新生的心理健康状况。方法:于2005-10在衡阳师范学院完成调查。采用整群抽样横断面调查方法,以衡阳师范学院2005级3089名新生为调查对象,运用症状自评量表对其进行集体测查。在统一指导语下,学生根据最近1周内的自我感觉答题,独立完成,当场收卷。结果数据运用光电阅读机(OMR2000)输入计算机心理测评工具箱标准版V3.0系统进行总分和因子分的统计。量表中没有回答的项目记为"没有",5个以上项目未答者视为问卷无效以及总分低于95分的问卷因缺乏可靠性均不进行分析。所有数据输入电脑后用SPSS11.0软件进行统计分析;群体差异比较用t和Z检验。结果:共发放3089份问卷,收回有效答卷2994份,有效率为96.92%,其中贫困新生有效答卷510份,占17.03%。问卷结果显示,师范院校贫困新生在人际关系、偏执和精神病性3项因子上的得分分别为1.86±0.54,1.70±0.48和1.58±0.43,明显高于非贫困新生(1.78±0.51,1.65±0.46,1.53±0.39,t=3.34,2.02,2.92,P<0.05)。从阳性因子的人数比率来看,师范院校贫困新生在总分阳性的人数比率为0.28,明显低于非贫困新生(0.33,Z=-2.27,P<0.05);而在人际关系、偏执和精神病性3项因子阳性的人数比率分别为0.35,0.30,0.16,明显高于非贫困新生(0.31,0.24,0.13,Z=1.73,2.72,1.71,P<0.05)。结论:师范院校贫困新生的整体心理健康状况并不比非贫困新生差,但是在人际关系敏感、偏执和精神病性3个问题上明显比非贫困新生要严重。     

The mind-set of teens towards food communications revealed by conjoint measurement and multi-food databases

We introduce a new type of study that combines self-profile of behaviors and attitudes regarding food together with responses to structured, systematically varied concepts about the food. We deal here with the responses of teens, for 28 different foods and beverages. The study creates a database that reveals how a person responds to different types of messaging about the food. We show how to develop the database for many different foods, from which one can compare foods to each other, or compare the performance of messages within a specific food.     

Stressful life events,Type A behavior,and the prediction of cardiovascular and total mortality over six years

The relationships between stressful life events and subsequent mortality and morbidity were determined prospectively over 6 years for 12,866 men participating in the Multiple Risk Factor Intervention Trial (MRFIT). Also evaluated was the impact of life events on cardiovascular outcomes for persons exhibiting and not exhibiting coronary prone (Type A) behavior. Subjects completed life events checklists at baseline and each of five annual visits. Participants were also administered the Jenkins Activity Survey measure of Type A behavior at baseline and a subsample of 3110 participants was categorized as to behavior type based on the structured interview assessment method. Cox proportional hazard analyses indicated that number of life events experienced during each of 6 years of follow-up was unrelated to risk in the subsequent year of CHD death or fatal plus nonfatal MI and was inversely related to total mortality. The impact of life events on cardiovascular risk did not differ by behavior type category.     

Neuropsychiatric correlates of traumatic brain injury (TBI) among Australian prison entrants

Primary objective: To investigate the association between reported past traumatic brain injury (TBI) and demographic, neuropsychiatric and criminographic parameters among individuals recently received into custody.

Research design: A random sample of men recently received into the New South Wales (Australia) criminal justice system were screened for a history of TBI and the details of up to five separate TBI episodes were obtained. We also screened for depression, psychosis, personality disorder, drug and alcohol use, and 'social connectedness'.

Main outcome and results: Among the 200 study participants, 82% reported past TBI. TBI was associated with a history of engagement in contact sports, school expulsion, daily illicit drug use, depression and psychosis.

Conclusions: Past TBI is common among prisoners entering the criminal justice system and, amongst other correlates, appears to be highly associated with increased rates of major mental illness.
