No association between cumulative traumatic experiences and sex in risk for posttraumatic stress disorder among human immunodeficiency virus-positive adults

This study examined the association between the type and number of traumatic experiences and the conditional risk for posttraumatic stress disorder (PTSD), stratified by sex, in human immunodeficiency virus (HIV). We evaluated 465 (114 male and 350 female) HIV-positive adults attending HIV clinics in Cape Town, South Africa. Demographic and clinical data were collected, and the participants were screened for current PTSD and traumatic event exposure using the Mini-International Neuropsychiatric Interview and the Life Events Checklist, respectively. The highest attributable risk for PTSD was derived from sexual assault (17.4%) and transport accidents (16.9%). Only sexual assault was significantly (p = 0.002) associated with current PTSD. Although sex had no effect on the prediction of current PTSD, HIVinfected men tended to experience more lifetime traumas than HIV-infected women, with the men having significantly higher rates of exposure than women to physical assault (p = 0.018) and assault with a weapon (p = 0.001). These data highlight the importance of considering trauma type in contributing to the burden of PTSD in HIV-infected adults.Web of Scienc

Reduced NAA-Levels in the NAWM of Patients with MS Is a Feature of Progression. A Study with Quantitative Magnetic Resonance Spectroscopy at 3 Tesla

Reduced N-acetyl-aspartate (NAA) levels in magnetic resonance spectroscopy (MRS) may visualize axonal damage even in the normal appearing white matter (NAWM). Demyelination and axonal degeneration are a hallmark in multiple sclerosis (MS).To define the extent of axonal degeneration in the NAWM in the remote from focal lesions in patients with relapsing-remitting (RRMS) and secondary progressive MS (SPMS).H-MR-chemical shift imaging (TR = 1500ms, TE = 135ms, nominal resolution 1ccm) operating at 3Tesla to assess the metabolic pattern in the fronto–parietal NAWM. Ratios of NAA to creatine (Cr) and choline (Cho) and absolute concentrations of the metabolites in the NAWM were measured in each voxel matching exclusively white matter on the anatomical T2 weighted MR images.No significant difference of absolute concentrations for NAA, Cr and Cho or metabolite ratios were found between RRMS and controls. In SPMS, the NAA/Cr ratio and absolute concentrations for NAA and Cr were significantly reduced compared to RRMS and to controls.In our study SPMS patients, but not RRMS patients were characterized by low NAA levels. Reduced NAA-levels in the NAWM of patients with MS is a feature of progression

Portraying the nature of corruption: Using an explorative case-study design

What is the nature of corruption in Western democracies? To answer this research question, the authors study 10 Dutch corruption cases in depth, looking at confidential criminal files. The cases allow them to sketch a general profile of a corruption case. The authors offer nine propositions to portray the nature of corruption. They conclude that corruption usually takes place within enduring relationships, that the process of becoming corrupt can be characterized as a slippery slope, and that important motives for corruption, aside from material gain, include friendship or love, status, and the desire to impress others. The explorative multiple case study methodology helps to expand our understanding of the way in which officials become corrupt. © 2008 The American Society for Public Administration
